Introduction: Indicators, such as mortality and complications, are commonly used to measure the quality of care. However, a more comprehensive assessment of surgical quality is captured using composite outcome measures such as Textbook Outcome (TO), Optimal Pancreatic Surgery, and a newer 'Ideal Outcome' (IO) measure. We reviewed our institutional experience to assess the impact of demographics, comorbidities, and operative variables on IO after pancreatoduodenectomy (PD). Methods: A retrospective study was conducted on PD patients at Northwell Health between 2009 and 2023. IO was determined by the absence of six adverse outcomes, including in-hospital mortality, Clavien-Dindo ≥ III complications, clinically-relevant postoperative pancreatic fistula, reoperation, hospital stay > 75th percentile, and readmission within 30 days. Logistic regression analyzed the effects of various factors on achieving IO. Results: Of the 578 patients who underwent PD, 248 (42.91%) achieved the IO. On multivariable analysis, factors associated with increased odds of achieving IO included neoadjuvant chemotherapy (OR 1.30, 95% CI 1.05–1.62) and the presence of neuroendocrine tumors (OR 3.37, 95% CI 1.35–8.41). Percutaneous transhepatic biliary drainage (PTBD) (OR 0.34, 95% CI 0.14–0.80) and older age (≥ 70 years) (OR 0.48, 95% CI 0.32–0.74) were associated with decreased odds of achieving IO. Patients with IO had significantly improved survival on Kaplan-Meier log-rank test (p = 0.001) as well as adjusted Cox analysis (HR 0.62 95% CI: 0.39–0.97). Conclusion: IO may offer a comprehensive metric for assessing PD outcomes, highlighting the impact of age, chemotherapy, biliary drainage, and tumor types. These findings suggest targeted interventions and quality improvements could enhance PD outcomes by addressing modifiable factors and refining clinical strategies. [ABSTRACT FROM AUTHOR]

Breast and gynecological cancers are common cancers with high mortality and have profound effects on the various physical functions of women. This study assessed trends in the number of hospitalizations, in-hospital mortality, length of stay (LOS), and hospital charges for female breast and gynecological cancer from 2004 to 2020. The data for this study come from the China Health Statistics Yearbook. Time trends of categorical variables were assessed with the Cochran-Armitage Test. The linear model was used to test for the trend of continuous variables. The hospitalizations for breast cancer increased from 15,204 to 276,387 (P for trend < 0.001) and gynecological cancer increased from 12,418 to 214,956 (P for trend < 0.001). The in-hospital mortality rate due to breast cancer decreased from 1.70 to 1.07% (P for trend < 0.001). Hospitalizations for both breast and gynecological cancer increased clearly, whether in urban or rural. The gap between urban and rural has narrowed. The average cost per hospitalization for breast cancer significantly increased. However, the average LOS for breast cancer gradually decreased (from 17.0 to 10.7 days, P for trend < 0.001). The average cost per hospitalization for gynecological cancer increased significantly. However, this steady downward trend was observed in the average LOS for gynecological cancer (from 10.34 to 6.69 days, P for trend = 0.003). The increase in hospitalizations and medical expenses for breast and gynecological cancer should encourage healthcare policymakers and healthcare system stakeholders to develop more cost-effective approaches to women's cancer management.

This study investigated sex differences in clinical characteristics and in-hospital outcomes of heart failure (HF) hospitalizations using the National Inpatient Sample data, 2016–2019. HF hospitalizations ≥ 41 years of age were included and stratified by sex. Study outcomes were in-hospital mortality, prolonged length of stay, mechanical ventilation, mechanical circulatory support, vasopressor use, and disposition other than home. Propensity score matched regression analysis was done to compare outcomes between sex. A total of 4,704,684 primary HF hospitalizations were included in the analysis. Of these, 2,447,784 (52.0%) were males and 2,256,899 (48.0%) were females. Regression analysis showed that females had significantly lower odds for mortality (aOR, 0.92, 95% CI: 0.89–0.94), mechanical ventilation (aOR, 0.89, 95% CI: 0.86–0.92), mechanical circulatory support (aOR, 0.54, 95% CI: 0.51–0.58), and vasopressor use (aOR, 0.71, 95% CI: 0.66–0.74), compared to males. However, the odds for prolonged length of stay (aOR, 1.05, 95% CI: 1.04–1.06) and disposition other than home (aOR, 1.32, 95% CI: 1.31–1.34) were significantly higher among females, compared to males. There were significant differences in outcomes between males and females hospitalized for HF. Further research is required to delineate how sex affects several aspects of HF, including epidemiology, risk factors, pathogenesis, and response to medications. [ABSTRACT FROM AUTHOR]

Sepsis is a clinical syndrome caused by infection, leading to organ dysfunction due to a dysregulated host response. In recent years, its high mortality rate has made it a significant cause of death and disability worldwide. The pathophysiological process of sepsis is related to the body's dysregulated response to infection, with microcirculatory changes serving as early warning signals that guide clinical treatment. The Peripheral Perfusion Index (PI), as an indicator of peripheral microcirculation, can effectively evaluate patient prognosis. This study aims to develop two new prediction models using PI and other common clinical indicators to assess the mortality risk of sepsis patients during hospitalization and within 28 days post-ICU admission. This retrospective study analyzed data from sepsis patients treated in the Intensive Care Unit of Peking Union Medical College Hospital between December 2019 and June 2023, ultimately including 645 patients. LASSO regression and logistic regression analyses were used to select predictive factors from 35 clinical indicators, and two clinical prediction models were constructed to predict in-hospital mortality and 28-day mortality. The models' performance was then evaluated using ROC curve, calibration curve, and decision curve analyses. The two prediction models performed excellently in distinguishing patient mortality risk. The AUC for the in-hospital mortality prediction model was 0.82 in the training set and 0.73 in the validation set; for the 28-day mortality prediction model, the AUC was 0.79 in the training set and 0.73 in the validation set. The calibration curves closely aligned with the ideal line, indicating consistency between predicted and actual outcomes. Decision curve analysis also demonstrated high net benefits for the clinical utility of both models. The study shows that these two prediction models not only perform excellently statistically but also hold high practical value in clinical applications. The models can help physicians accurately assess the mortality risk of sepsis patients, providing a scientific basis for personalized treatment. [ABSTRACT FROM AUTHOR]

Background: The introduction of Emergency Medicine in Rwanda in 2015 has been associated with a mortality reduction in patients presenting to Kigali University Teaching Hospital (KUTH). In the context of increasing numbers of critically ill patients presenting to Emergency Departments (ED) globally, the aim of this study was to describe the characteristics of critically ill patients, the critical care interventions performed, and the outcomes of critically ill patients presenting to the KUTH ED with the goal of informing future research into the root causes of mortality of critically ill ED patients and of identifying high yield topics for didactic and procedural training. Methods: A descriptive observational prospective cohort pilot study analyzed all patients ≥15 years who presented to KUTH between April and June 2022 with modified South African Triage Scores of Red with alarm, Red without alarm, and Orange. Results: Of 320 patients, 66.9% were male and median age was 40 years. Patients were triaged as Orange (65.3%), Red without alarm (22.8%), and Red with alarm (11.9%). Presentations were categorized as: medical emergencies (48.0%), traumatic injury (44.5%), and surgical emergencies (7.6%). Median length of stay was 31 h (IQR 28, 56) and boarding was 23 h (IQR 8, 48). Overall mortality was 12.2% and highest among medical emergencies (16.5%, p = 0.048) and increased significantly with triage color: Red with alarm (47.4%), Red without alarm (16.4%), and Orange (4.3%, p < 0.0001). Cardiopulmonary resuscitation (CPR) (10.3%), endotracheal intubation (8.8%), and vasopressor administration (3.1%) were the most frequent critical interventions performed. Survival after cardiac arrest was 9.1% and 32.1% after intubation. Mortality was associated with the following interventions: CPR, intubation, and use of vasopressors (p < 0.05). Conclusions: This pilot study identified the most common critical care interventions performed and a high mortality among patients who required these interventions in the ED of a tertiary teaching hospital in Rwanda. These findings will inform didactics and procedural training for emergency care providers. Future research should focus on the root causes of mortality in these specific patient populations and identify areas of system strengthening to reduce mortality. [ABSTRACT FROM AUTHOR]

Purpose: Acute hypoxaemic respiratory failure (AHRF) is a common reason for intensive care unit (ICU) admission. However, patient characteristics, outcomes, and trends over time are unclear. We describe the epidemiology and outcomes of patients with AHRF over time. Methods: In this binational, registry-based study from 2005 to 2022, we included all adults admitted to an Australian or New Zealand ICU with an arterial blood gas within the first 24 h of ICU stay. AHRF was defined as a partial pressure of oxygen/inspired oxygen ratio (PaO2/FiO2) ≤ 300. The primary outcome was adjusted in-hospital mortality, categorised based on PaO2/FiO2 (mild: 200–300, moderate: 100–200, and severe < 100, and non-linearly). We investigated how adjusted mortality evolved based on temporal trends (by year of admission), sex, age, admission diagnosis and the receipt of mechanical ventilation. Results: Of 1,560,221 patients, 826,106 (52.9%) were admitted with or developed AHRF within the first 24 h of ICU stay. Of these 826,106 patients, 51.4% had mild, 39.3% had moderate, and 9.3% had severe AHRF. Compared to patients without AHRF (5.3%), patients with mild (8%), moderate (14.2%) and severe (29.9%) AHRF had higher in-hospital mortality rates. As PaO2/FiO2 ratio decreased, adjusted in-hospital mortality progressively increased, particularly below an inflection point at a PaO2/FiO2 ratio of 200. The adjusted in-hospital mortality for all patients decreased over time (13.3% in 2005 to 8.2% in 2022), and this trend was similar in patients with and without AHRF. Conclusion: The healthcare burden due to AHRF may be larger than expected, and mortality rates remain high in severe AHRF. Although mortality has decreased over time, this may reflect improvements in ICU care in general, rather than specifically in AHRF. More research is required to earlier identify AHRF and stratify these patients at risk of deterioration early, and to validate our findings. [ABSTRACT FROM AUTHOR]

Purpose: Predicting infection risk in carbapenem-resistant Acinetobacter baumannii (CRAB) colonized patients may help in improving timely appropriate antibiotic therapy. This study aims to explore risk factors for developing infections in hospitalized patients with previous CRAB colonization. Methods: We performed an observational retrospective cohort study at ASST Sette Laghi-Varese Hospital between January 2020 and December 2022. All consecutive adult (> 18 years old) hospitalized patients with documented colonization by CRAB at any anatomical site or with CRAB infections preceded by CRAB colonization were included. Univariate and multivariate analyses were performed to investigate infection risk factors. Results: Overall, 144 patients were included in the study: 104 colonized only and 40 infected patients. Colonization and infection rates significantly changed over the years (2020–2022, p < 0.001). The incidence of infections in CRAB carriers was 27.8% (40/144). Median time from colonization to infection was 4 days (IQR 1-8.5). Overall, inhospital mortality was 32.7% and 55.0% in colonized only and infected patients, respectively. At the multivariable logistic regression cardiovascular disease (OR 5.83, 95% CI 1.12–30.43, p = 0.037), COVID-19 (OR 3.72, 95% CI 1.16–11.91, p = 0.027) and intensive care unit (ICU) admission (OR 8.83, 95% CI 2.94–26.51, p < 0.001) were risk factors independently associated with cardiovascular disease CRAB infection after colonization. Conclusions: We observed an increased infection risk in patients colonized with CRAB with cardiovascular disease, COVID-19 and admitted in ICU setting. Additional evidence is needed to identify predictors of infection in colonized patients. [ABSTRACT FROM AUTHOR]

Purpose: Prognostic scores require fluctuating values, such as respiratory rate, which are unsuitable for retrospective auditing. Therefore, this study aimed to develop and validate a predictive model for in-hospital mortality associated with gastrointestinal surgery for retrospective auditing. Methods: Data from patients with bacteremia related to gastrointestinal surgery performed at Shizuoka General Hospital between July 2006 and December 2021 were extracted from a prospectively maintained database. Patients suspected of having a positive blood culture with contaminating bacteria or missing laboratory data were excluded. The remaining patients were randomly assigned in a 2:1 ratio to the deviation and validation cohorts. A logistic regression model estimated the odds ratios (ORs) and created a predictive model for in-hospital mortality. The model was evaluated using receiver operating characteristic (ROC) curves and calibration plots. Results: Of 20,637 gastrointestinal surgeries, 398 resulted in bacteremia. The median age of patients with bacteremia was 72 years, and 66.1% were male. The most common pathogens were Staphylococcus (13.9%), followed by Bacteroides (12.4%) and Escherichia (11.4%). Multivariable logistic regression showed that creatinine abnormality (P < 0.001, OR = 3.39), decreased prognostic nutritional index (P < 0.001, OR = 0.90/unit), and age ≥ 75 years (P = 0.026, OR = 2.89) were independent prognostic factors for in-hospital mortality. The area under the ROC curve of the predictive model was 0.711 in the validation cohort. The calibration plot revealed that the model slightly overestimated mortality in the validation cohort. Conclusions: Using age, creatinine level, albumin level, and lymphocyte count, the model accurately predicted in-hospital mortality after bacteremia infection related to gastrointestinal surgery, demonstrating its suitability for retrospective audits.

Background: The objective of this study was to assess the trend from open to modern minimally invasive (laparoscopic and robot-assisted) surgical techniques for colorectal cancer (CRC) in Germany, with a particular focus on hospital mortality, postoperative complications, and length of hospital stay. Methods: A multicenter cross-sectional study was conducted using data from 36 German hospitals, encompassing 1,250,029 cases from January 2019 to December 2023. The study included all hospitalized patients aged ≥ 18 with CRC who underwent surgery. Surgical cases were categorized as open or minimally invasive. Outcomes assessed included in-hospital mortality, morbidity, and hospital length of stay. Statistical analyses involved multivariable logistic and linear regression models adjusted for main diagnosis, metastasis presence, age, sex, and comorbidities. Results: The study included 4525 CRC cases: 2767 underwent open surgery and 1758 underwent minimally invasive surgery (173 robotic). In-hospital mortality was significantly higher in open surgery (6.1% vs. 1.7%). Open surgery was also significantly associated with higher rates of acute post-hemorrhagic anemia (OR: 2.38; 95% CI: 1.87–3.02), respiratory failure (OR: 1.71; 95% CI: 1.34–2.18), and intraoperative and postprocedural complications (OR: 3.64; 95% CI: 2.83–4.70). Average hospital stay was longer for open surgery (19.5 days vs. 11.0 days). Conclusion: Despite the advantages of minimally invasive surgery, including reduced mortality, morbidity, and shorter hospital stays, open surgery remains the predominant approach for CRC in Germany. These findings underscore the need for increased adoption of minimally invasive techniques and highlight the potential benefits of shifting toward minimally invasive methods to enhance the overall quality of CRC care.

Data describing the use of extracorporeal membrane oxygenation (ECMO) in pediatric acute liver failure (PALF) are scarce. Thus, we aimed to describe the use of ECMO in patients with PALF using the data from the Extracorporeal Life Support Organization (ELSO) Registry between January 1, 2010, to December 31, 2022. We described patients' characteristics at ECMO initiation, outcome, and factors associated with mortality. A total of 335 children underwent ECMO support in the context of PALF. Veno-arterial (VA) ECMO was the most prevalent mode (66.6%), followed by veno-venous (VV) ECMO (33.4%). Extracorporeal cardiopulmonary resuscitation (ECPR) was used in 21.5% of the cardiac arrest. In-hospital mortality was 66.6%. Both higher lactate (OR 1.128, CI 1.06–1.209, p < 0.001) and PaCO2 (OR 1.022, CI 1.001–1.047, p 0.05) levels before ECMO reported greater odds of mortality. Low body weight, persistence of hyperlactatemia (OR 0.985, CI 0.973–0.997, p 0.013), and hyperbilirubinemia (OR 2.477, CI 1.042–6.100, p 0.045) after 24 h from ECMO deployment were associated to greater odds of mortality. Conclusions: Our results suggest that the use of ECMO for the management of respiratory and cardiac failure in patients with PALF should be considered with caution and that further research is needed to understand its role in this specific high-risk population. What is known: • Pediatric acute liver failure (PALF) is a clinical syndrome associated with significant morbidity and mortality. • Data on the use of extracorporeal membrane oxygenation (ECMO) in the context of PALF are scarce and controversial. What is new: • ECMO to manage acute respiratory and/or cardiac failure in the context of PALF should be considered with caution. • Bleeding and thrombotic complications in children with acute liver failure receiving ECMO are similar to the ones reported in the general pediatric population.

Purpose: This study investigated whether the oral vasopressin V2 receptor antagonist tolvaptan has beneficial effects on mortality in real-world congestive heart failure (CHF) patients with hypoperfusion (i.e. the wet–cold pattern), from the viewpoint of cardiorenal syndrome. Methods: Data on 5511 consecutive CHF patients were extracted from the Tokyo CCU Network data registry. Congestion and hypoperfusion were defined by Nohria–Stevenson clinical profiles at the time of hospitalization. Propensity scores for tolvaptan use were calculated for each patient and used to assemble two matched cohorts of patients receiving tolvaptan or not in the CHF with and without hypoperfusion groups. Results: Of the entire study cohort, 1073 patients (19%) had CHF with hypoperfusion (i.e. the wet–cold pattern). In-hospital mortality was significantly higher for CHF patients with than without hypoperfusion (log-rank, P < 0.001). The rate of tolvaptan use did not differ significantly between CHF patients with and without hypoperfusion (15% vs. 14%, respectively; P = 0.7848). In the propensity-matched CHF with hypoperfusion cohort, there was a significant association between the use of tolvaptan and a reduction in in-hospital mortality (log-rank, P = 0.0052). Conversely, in the matched CHF without hypoperfusion cohort, tolvaptan use was not associated with in-hospital mortality (log-rank, P = 0.4417). Conclusion: There was a significant association between the use of tolvaptan and a reduction in in-hospital mortality in CHF patients with, but not without, hypoperfusion. These findings hint at possible individualized therapies for patients with CHF. [ABSTRACT FROM AUTHOR]

Objective: To evaluate the effectiveness and safety of Chinese medicine (CM) in the treatment of coronavirus disease 2019 (COVID-19) in China. Methods: A multi-center retrospective cohort study was carried out, with cumulative CM treatment period of ⩾3 days during hospitalization as exposure. Data came from consecutive inpatients from December 19, 2019 to May 16, 2020 in 4 medical centers in Wuhan, China. After data extraction, verification and cleaning, confounding factors were adjusted by inverse probability of treatment weighting (IPTW), and the Cox proportional hazards regression model was used for statistical analysis. Results: A total of 2,272 COVID-19 patients were included. There were 1,684 patients in the CM group and 588 patients in the control group. Compared with the control group, the hazard ratio (HR) for the deterioration rate in the CM group was 0.52 [95% confidence interval (CI): 0.41 to 0.64, P<0.001]. The results were consistent across patients of varying severity at admission, and the robustness of the results were confirmed by 3 sensitivity analyses. In addition, the HR for all-cause mortality in the CM group was 0.29 (95% CI: 0.19 to 0.44, P<0.001). Regarding of safety, the proportion of patients with abnormal liver function or renal function in the CM group was smaller. Conclusion: This real-world study indicates that the combination of a full-course CM therapy on the basic conventional treatment, may safely reduce the deterioration rate and all-cause mortality of COVID-19 patients. This result can provide the new evidence to support the current treatment of COVID-19. Additional prospective clinical trial is needed to evaluate the efficacy and safety of specific CM interventions. (Registration No. ChiCTR2200062917) [ABSTRACT FROM AUTHOR]

Background: Acute exacerbations of COPD (AECOPD) are common and significantly contribute to mortality in patients with COPD. Prognostic scores can assist clinicians in making tailored decisions to manage AECOPD. In the current study, we therefore aimed to evaluate the performance of the Noninvasive Ventilation Outcomes (NIVO) score, originally designed to assess in-ICU mortality, in predicting 1 year mortality and NIV failure in AECOPD. Methods: This retrospective study analyzed data from patients hospitalized for AECOPD requiring mechanical ventilation between January 1st, 2018, and December 31st, 2022. Mortality was assessed at the end of ICU stay and 1 year after admission, while NIV failure was defined as intubation or death without intubation. Results: Among 302 ICU admissions of COPD patients, 190 patients with AECOPD requiring mechanical ventilation were included. Of these, 44 (23%) died in the ICU, 62 out of 184 (34%) failed NIV, and 78 (41%) died within 1 year of admission. Patients who died in ICU or experienced NIV failure had more severe COPD and more impaired blood gas parameters at admission. The NIVO score demonstrated an AUC of 0.68 in predicting 1-year mortality and an AUC of 0.85 in predicting NIV failure. A NIVO score over 7 was associated with higher 1-year mortality and NIV failure (HR of 4.4 [1.8–10.9] and 41.6 [5.6–307.9], respectively). Conclusion: Beyond predicting in-ICU mortality, the NIVO-score is a reliable tool in predicting 1-year mortality and NIV failure in AECOPD. [ABSTRACT FROM AUTHOR]

To examine temporal changes in patient characteristics, the incidence rate of surgical intervention, and the three-year mortality rate for patients undergoing surgical intervention for mitral valve stenosis (MS) from 2001 to 2021 in Denmark. Utilizing Danish nationwide registries, we identified all adult patients undergoing first-time surgical intervention for MS (2001–2021). Temporal changes in the incidence rate of surgical intervention across calendar periods were investigated (2001–2005, 2006–2010, 2011–2015, and 2016–2021). Using Kaplan-Meier estimates, we computed temporal changes in three-year all-cause mortality across calendar periods. With multivariable Cox regression analysis, we assessed the adjusted rates of mortality. We included 256 patients (median age 60.3 years, 31.3% males). A stepwise decrease in the burden of chronic heart failure was identified (2001–2005: 54%, and 2016–2021: 20%, p-value < 0.001 for trend), while the burden of atrial fibrillation seemed stable (2001–2005: 51%, and 2016–2021: 46%, p-value = 0.27 for trend). The proportion of patients with rheumatic MS was 64% in 2001–2005 and 33% in 2016–2021, p-value < 0.001 for trend. 28 patients (10.9%) had mitral valve surgery prior to the first-time surgical intervention for MS. A stepwise decrease in the incidence rate of surgical intervention was observed: 3.3 cases per million person-years in 2001–2005 and 2.2 in 2016–2021. The incidence of patients diagnosed with first-time MS remained stable over calendar periods (2001–2005: 54.5 incidences per million person-years, and 2016–2021: 41.9, p-value = 0.46 for trend). The in-hospital mortality was 8.6% and the three-year mortality after surgical discharge was 9.0%, and we found no difference over calendar periods in either crude estimates or adjusted analysis. From nationwide data across three decades, we identified that the incidence of surgical interventiondecreased significantly within the past 20 years, while all-cause mortality remained stable. The burden of heart failure decreased, while the burden of atrial fibrillation remained stable over the study period. [ABSTRACT FROM AUTHOR]

Background: Chest pain is a frequent cause of health care contacts. We examined the prehospital management, in-hospital discharge diagnoses, and mortality of patients calling a non-emergency and emergency medical service with chest pain. Methods: The Copenhagen Emergency Medical Services (EMS) consists of a non-emergency medical helpline (calls to 1813) and emergency medical service (1-1-2 calls). We included all calls to the Copenhagen EMS with a primary complaint of chest pain from 2014 to 2018 in Copenhagen, Denmark. The outcomes were: emergency response (ambulance dispatch, other transports/self-transport/home visits, self-care, and unknown/cancelled response), in-hospital diagnosis within 7 days after the call (cardiovascular, pulmonary, or other non-cardiovascular/pulmonary) and 30-day mortality. Results: Among 4,834,071 calls, 91,671 were registered with chest pain at the Copenhagen EMS. The first call for each patient was kept for analysis (n = 66,762). In total, 91.4% were referred to the hospital, 75.8% (n = 50,627) received an ambulance and 15.6% (n = 10,383) received other transport/self-transport/home visits. Overall, 26.9% (n = 17,937) were diagnosed with a cardiovascular disease, 5.2% (n = 3,490) a pulmonary disease, 52.8% (n = 35.242) other non-cardiovascular/pulmonary disease, and 15.1% (n = 10,093) received no diagnosis. Among ambulance-transported patients, the prevalence of cardiovascular discharge diagnoses was higher (32.1%) and fewer received no diagnosis (11.0%). Cardiovascular disease was less prevalent among patients not transported by ambulance and patients not referred to hospital at all (2-13.4%) and in patients ≤ 40 years of age (< 10%). The 30-day mortality was below 5% regardless of diagnosis (0.6-4%), and 65,704 (98.4%) were still alive 30 days later. Conclusion: Nearly all patients calling with chest pain were referred for treatment. Among ambulance-transported patients, around half of the patients did not have a cardiovascular/pulmonary disease. While current practices appear reasonable, improved differentiation of chest pain patients in telephone consultations could potentially both improve the treatment and management of these patients and reduce the in-hospital burden of non-acute chest pain consultations.

Fluid management remains a critical challenge in the treatment of septic shock, with individualized approaches lacking. This study aims to develop a statistical model based on transcriptomics to identify subgroups of septic shock patients with varied responses to fluid strategy. The study encompasses 494 septic shock patients. A benefit score is derived from the transcriptome space, with higher values indicating greater benefits from restrictive fluid strategy. Adherence to the recommended strategy is associated with a hazard ratio of 0.82 (95% confidence interval: 0.64–0.92). When applied to the baseline hospital mortality rate of 16%, adherence to the recommended fluid strategy could potentially lower this rate to 13%. A proteomic signature comprising six proteins is developed to predict the benefit score, yielding an area under the curve of 0.802 (95% confidence interval: 0.752–0.846) in classifying patients who may benefit from a restrictive strategy. In this work, we develop a proteomic signature with potential utility in guiding fluid strategy for septic shock patients. Fluid management in septic shock lacks personalized approaches, which are critical for improving patient outcomes. Here, the authors show that a proteomic signature can help identify patients who may benefit from a restrictive fluid strategy, potentially reducing hospital mortality rates. [ABSTRACT FROM AUTHOR]

Corticosteroids have always been recommended for severe cases of COVID-19. However, the efficacy of treatment with corticosteroids for COVID-19 during the SARS-CoV-2 omicron outbreak in China has not been reported. Clinical data from 406 patients hospitalized for severe/critical COVID-19 from December 2022 to January 2023 at six hospitals in Chongqing were retrospectively analyzed. The primary outcome was all-cause mortality at 28 days in the groups with and without corticosteroids treatment after propensity score matching (PSM). Secondary outcomes were to compare in-hospital mortality and length of survival time with corticosteroids and those without corticosteroids. This study included 406 patients with severe or critical COVID-19, divided into the corticosteroids group (231, 56.9%) and non-corticosteroids group (175, 43.1%). After PSM, the use of corticosteroids did not reduce all-cause mortality at 28 days (42.5% vs. 39.1%). Univariate analysis showed that corticosteroids were not associated with improved all-cause mortality at 28 days [hazard ratio (HR), 1.019; 95% confidence interval (CI), 0.639–1.623; p = 0.938]. Multivariate analysis showed similar results (HR, 1.047; 95% CI, 0.633–1.732; p = 0.858). Among non-survivors, the survival time was significantly larger in those who received corticosteroids compared with the non-corticosteroid users [median 13 (IQR 6.5–15.5) vs. 6 (4-11.25), p = 0.007]. The use of systemic corticosteroids in severe/critical COVID-19 may provide certain potential survival benefits but does not improve prognosis. [ABSTRACT FROM AUTHOR]

Triglyceride-glucose (TyG) index has emerged as a novel biomarker for detecting insulin resistance (IR) and has been proven to be associated with various diseases. However, its correlation with the prognosis of severe sepsis remains unraveled. This retrospective cohort study utilized patient records from the Medical Information Mart for Intensive Care (MIMIC-IV, version 2.2) to examine the outcomes of patients with sepsis. The primary outcomes were hospital mortality and intensive care unit (ICU) mortality. The correlation between the TyG index and outcomes was evaluated through the Kaplan-Meier method, the Log-rank test, and univariate and multivariate Cox regression analyses. Additionally, restricted cubic spline (RCS) regression analysis was employed to delve into the nonlinear relationship between baseline TyG index and outcomes, with trend significance assessed through quartile levels. Subgroup analyses were conducted to evaluate the consistency of the TyG index's prognostic value across various influencing factors. The study included 1,742 patients with sepsis requiring intensive care. The in-hospital mortality rate was 19.75% (344/1,742), and the ICU mortality rate was 14.75% (257/1,742). Cox regression analysis revealed that, in comparison to the first quartile (Q1), patients in the fourth quartile (Q4) had a 63% higher risk of in-hospital mortality (HR 1.63 [95% CI 1.22 to 2.18], P < 0.01) and a 79% higher risk of ICU mortality (HR 1.79 [95% CI 1.28 to 2.51], P < 0.001). Model 3 showed that ICU mortality risks for Q4, Q3, and Q2 were 240%, 75%, and 33% higher, respectively (HR 3.40 [95% CI 2.24 to 5.16], P < 0.001; HR 1.75 [95% CI 1.16 to 2.63], P = 0.007; HR 1.33 [95% CI 1.20 to 1.53], P < 0.001). RCS regression analysis identified a nonlinear association between the TyG index and mortality (overall P < 0.001; P for nonlinearity < 0.001, with an inflection point at 8.9). Subgroup analysis showed that the effect size and direction were consistent across different subgroups, suggesting the stability of the results. This study demonstrates that a higher TyG index is significantly associated with increased in-hospital and ICU mortality risk in critically ill sepsis patients, with evidence of non-linear correlation. Therefore, the TyG index helps identify the mortality prognosis of sepsis patients in the ICU. [ABSTRACT FROM AUTHOR]

Background: Modified furosemide responsiveness index (mFRI) is a novel biomarker for assessing diuretic response and AKI progression in patients with early AKI. However, the comparative predictive performance of mFRI and novel renal biomarkers for adverse renal outcomes remains unclear. In a single-center prospective study, we aimed to evaluate the discriminatory abilities of mFRI and other novel renal biomarkers in predicting AKI progression and prognosis in patients with initial mild and moderate AKI (KDIGO stage 1 to 2). Results: Patients with initial mild and moderate AKI within 48 h following cardiac surgery were included in this study. The mFRI, renal biomarkers (including serum or urinary neutrophil gelatinase-associated lipocalin [sNGAL or uNGAL], serum cystatin C, urinary N-acetyl-beta-D-glycosaminidase [uNAG], urinary albumin-to-creatinine ratio) and cytokines (TNF, IL-1β, IL-2R, IL-6, IL-8, and IL-10) were measured at AKI diagnosis. The mFRI was calculated for each patient, which was defined as 2-hour urine output divided by furosemide dose and body weight. Of 1013 included patients, 154 (15.2%) experienced AKI progression, with 59 (5.8%) progressing to stage 3 and 33 (3.3%) meeting the composite outcome of hospital mortality or receipt of renal replacement therapy (RRT). The mFRI showed non-inferiority or potential superiority to renal biomarkers and cytokines in predicting AKI progression (area under the curve [AUC] 0.80, 95% confidence interval [CI] 0.77–0.82), progression to stage 3 (AUC 0.87, 95% CI 0.85–0.89), and composite outcome of death and receipt of RRT (AUC 0.85, 95% CI 0.82–0.87). Furthermore, the combination of a functional biomarker (mFRI) and a urinary injury biomarker (uNAG or uNGAL) resulted in a significant improvement in the prediction of adverse renal outcomes than either individual biomarker (all P < 0.05). Moreover, incorporating these panels into clinical model significantly enhanced its predictive capacity for adverse renal outcomes, as demonstrated by the C index, integrated discrimination improvement, and net reclassification improvement (all P < 0.05). Conclusions: As a rapid, cost-effective and easily accessible biomarker, mFRI, exhibited superior or comparable predictive capabilities for AKI progression and prognosis compared to renal biomarkers in cardiac surgical patients with mild to moderate AKI. Trial registration: Clinicaltrials.gov, NCT04962412. Registered July 15, 2021, https://clinicaltrials.gov/ct2/show/NCT04962412?cond=NCT04962412&draw=2&rank=1. Highlights: The mFRI is a rapid, cost-effective and easily accessible biomarker. The mFRI exhibited superior or comparable predictive capabilities for AKI progression and prognosis compared to renal biomarkers and cytokines in cardiac surgical patients with mild to moderate AKI. Combining the functional biomarker mFRI with a urinary injury biomarker (uNAG or uNGAL) enhanced predictive accuracy for adverse renal outcomes. [ABSTRACT FROM AUTHOR]

Background: Bleeding events are common complications in critically ill patients with haematological malignancies. The objective of this study was to assess the incidence and identify determinants of ICU-acquired severe bleeding events in critically ill patients with haematological malignancies. We conducted a single-center retrospective study including all adult patients with a history of haematological malignancy requiring unplanned ICU admission over a 12-year period (2007–2018). The primary endpoint was the occurrence of ICU-acquired (i.e. after the first 24 h in the ICU) severe bleeding events, as defined as grades 3 or 4 of the World Health Organization classification. Results: A total of 1012 patients were analysed, mainly with a diagnosis of lymphoma (n = 434, 42.9%) and leukaemia or myelodysplastic syndrome (n = 266, 26.3%). Most patients were recently diagnosed (n = 340, 33.6%) and under active cancer treatment within the last 3 months (n = 604, 59.7%). The main cause for admission was infection (n = 479, 47.3%), but a significant proportion of patients were admitted for a primary haemorrhage (n = 99, 10%). ICU-acquired severe bleeding events occurred in 109 (10.8%) patients after 3.0 days [1.0–7.0] in the ICU. The main source of bleeding was the gastrointestinal tract (n = 44, 40.3%). Patients experiencing an ICU-acquired severe bleeding event displayed prolonged in-ICU length of stay (9.0 days [1.0–6.0] vs. 3.0 [3.5–15.0] in non-bleeding patients, p < 0.001) and worsened outcomes with increased in-ICU and in-hospital mortality rates (55% vs. 18.3% and 65.7% vs. 33.1%, respectively, p < 0.001). In multivariate analysis, independent predictors of ICU-acquired severe bleeding events were chronic kidney disease (cause-specific hazard 2.00 [1.19–3.31], p = 0.008), a primary bleeding event present at the time of ICU admission (CSH 4.17 [2.71–6.43], p < 0.001), non-platelet SOFA score (CSH per point increase 1.06 [1.01–1.11], p = 0.02) and prolonged prothrombin time (CSH per 5-percent increase 0.90 [0.85–0.96], p = 0.001) on the day prior to the event of interest. Conclusions: Major bleeding events are common complications in critically ill patients with haematological malignancies and are associated with a worsened prognosis. We identified relevant risk factors of bleeding which may prompt closer monitoring or preventive measures. [ABSTRACT FROM AUTHOR]

Background: Peripheral veno-arterial extracorporeal membrane oxygenation (pECMO) has become the first-line device in refractory cardiogenic shock (rCS). Some pECMO complications can preclude any bridging strategies and a peripheral-to-central ECMO (cECMO) switch can be considered as a bridge-to-decision. We conducted this study to appraise the in-hospital survival and the bridging strategies in patients undergoing peripheral-to-central ECMO switch. Methods: This retrospective monocenter study included patients admitted to a ECMO-dedicated intensive care unit from February 2006 to January 2023. Patients with rCS requiring pECMO switched to cECMO were included. Patients were not included when the cECMO was the first mechanical circulatory support. Results: Eighty patients, with a median [IQR25-75] age of 44 [29–53] years at admission and a female-to-male sex ratio of 0.6 were included in the study. Refractory pulmonary edema was the main switching reason. Thirty patients (38%) were successfully bridged to: heart transplantation (n = 16/80, 20%), recovery (n = 10/80, 12%) and ventricle assist device (VAD, n = 4/30, 5%) while the others died on cECMO (n = 50/80, 62%). The most frequent complications were the need for renal replacement therapy (76%), hemothorax or tamponade (48%), need for surgical revision (34%), mediastinitis (28%), and stroke (28%). The in-hospital and one-year survival rates were 31% and 27% respectively. Myocardial infarction as the cause of the rCS was the only variable independently associated with in-hospital mortality (HR 2.5 [1.3–4.9], p = 0.009). Conclusions: The switch from a failing pECMO support to a cECMO as a bridge-to-decision is a possible strategy for a very selected population of young patients with a realistic chance of heart function recovery or heart transplantation. In this setting, cECMO allows patients triage preventing from wasting expensive and limited resources. [ABSTRACT FROM AUTHOR]

Purpose: Underweight patients experience poor outcomes after elective orthopaedic procedures. The effect of underweight body mass index (BMI) on complications after acetabular fracture is not well-described. We evaluate if underweight status is associated with inpatient complications after acetabular fractures. Methods: Adult patients (≥ 18 years) presenting with acetabular fracture between 2015 and 2019 were identified from Trauma Quality Program data. Adjusted odds (aOR) of any inpatient complication or mortality were compared between patients with underweight BMI (< 18.5 kg/m2) and normal BMI (18.5–25 kg/m2) using multivariable logistic regression and stratifying by age ≥ 65 years. Results: The 1299 underweight patients aged ≥ 65 years compared to 11,629 normal weight patients experienced a 1.2-times and 2.7-times greater aOR of any complication (38.6% vs. 36.6%, p = 0.010) and inpatient mortality (7.9% vs. 4.2%, p < 0.001), respectively. The 1688 underweight patients aged 18–64 years compared to 24,762 normal weight patients experienced a 1.2-times and 1.5-times greater aOR of any inpatient complication (38.9% vs. 34.8%, aOR p = 0.006) and inpatient mortality (4.1% vs. 2.5%, p < 0.001), respectively. Conclusion: Underweight adult patients with acetabular fracture are at increased risk for inpatient complications and mortality, particularly those ≥ 65 years old. Level of Evidence: Prognostic Level III. [ABSTRACT FROM AUTHOR]

Purpose: The aim of this study was to compare the effect of a pressure-controlled strategy allowing non-synchronised unassisted spontaneous ventilation (PC-SV) to a conventional volume assist-control strategy (ACV) on the outcome of patients with acute respiratory distress syndrome (ARDS). Methods: Open-label randomised clinical trial in 22 intensive care units (ICU) in France. Seven hundred adults with moderate or severe ARDS (PaO2/FiO2 < 200 mmHg) were enrolled from February 2013 to October 2018. Patients were randomly assigned to PC-SV (n = 348) or ACV (n = 352) with similar objectives of tidal volume (6 mL/kg predicted body weight) and positive end-expiratory pressure (PEEP). Paralysis was stopped after 24 h and sedation adapted to favour patients' spontaneous ventilation. The primary endpoint was in-hospital death from any cause at day 60. Results: Hospital mortality [34.6% vs 33.5%, p = 0.77, risk ratio (RR) = 1.03 (95% confidence interval [CI] 0.84–1.27)], 28-day mortality, as well as the number of ventilator-free days and organ failure-free days at day 28 did not differ between PC-SV and ACV groups. Patients in the PC-SV group received significantly less sedation and neuro-muscular blocking agents than in the ACV group. A lower proportion of patients required adjunctive therapy of hypoxemia (including prone positioning) in the PC-SV group than in the ACV group [33.1% vs 41.3%, p = 0.03, RR = 0.80 (95% CI 0.66–0.98)]. The incidences of pneumothorax and refractory hypoxemia did not differ between the groups. Conclusions: A strategy based on PC-SV mode that favours spontaneous ventilation reduced the need for sedation and adjunctive therapies of hypoxemia but did not significantly reduce mortality compared to ACV with similar tidal volume and PEEP levels.

Background: Status epilepticus (SE) imposes a significant burden in terms of in-hospital mortality and costs, but the relationship between SE causes, patient comorbidities, mortality, and cost remains insufficiently understood. We determined the in-hospital mortality and cost-driving factors of SE using a large and comprehensive database. Methods: We conducted a retrospective cohort study involving patients experiencing their first hospitalization with an ICD-10 code diagnosis of SE, spanning from January 1, 2015, to December 31, 2019, using the French health insurance database which covers 99% of population. Patient characteristics, SE causes, Intensive Care Unit (ICU) admissions, mechanical ventilation, discharge status, and health insurance costs were extracted for each hospitalization. Results: We identified 52,487 patients hospitalized for a first SE. In-hospital mortality occurred in 11,464 patients (21.8%), with associated factors including age (Odds Ratio [OR], 10.3, 95% Confidence Interval [CI] 7.87–13.8 for ages over 80 compared to 10–19), acute causes (OR, 15.3, 95% CI 13.9–16.8 for hypoxic cause), tumors (OR, 1.75, 95% CI 1.63–1.8), comorbidities (OR, 3.00, 95% CI 2.79–3.24 for 3 or more comorbidities compared to 0), and prolonged mechanical ventilation (OR, 2.61, 95% CI 2.42–2.82). The median reimbursed cost for each SE hospitalization was 6517€ (3364–13,354), with cost factors mirroring those of in-hospital mortality. Conclusion: Causes and co-morbidities are major determinants of mortality and hospital costs in status epilepticus, and factors associated with higher mortality are also often associated with higher costs. Further studies are needed to identify their long-term effects. [ABSTRACT FROM AUTHOR]

Background: The neutrophil-to-lymphocyte ratio (NLR) proves to be a convenient and cost-effective marker with studies showing that a high NLR can serve as a mortality indicator in burn cases. We conducted a meta-analysis aiming to explore whether on-admission NLR values could serve as predictors of mortality in burn patients. Methods: PubMed, Web of Science, Scopus and Embase were searched from inception until January 2024. We included all studies investigating burn patients that contain information on the NLR value at the time of hospital admission and mortality outcomes. The studies were critically appraised using the NIH Quality Assessment Tool. Results: Nine studies fulfilled our criteria with a total population of 1837 participants, including 1526 survivor Burn patients and 311 non-survivor Burn patients. The overall mean difference measured by random model showed a significant increase in NLR by 5.06 (95% CI 3.42, 6.68) p ≤ 0.001 for the non-survivor group over the survivors group with heterogeneity I2 = 67.33%, p ≤ 0.001. A meta-regression was done to investigate the potential source of heterogeneity among studies. The results showed that age (p = 0.394), gender (p = 0.164), and sample size (p = 0.099) did not contribute to the source of heterogeneity, however, the burn surface area contributed significantly (p = 0.002). A leave-one-out meta-analysis was done, showing that omitting Le Qui et al., leads to significantly decrease the heterogeneity to be I2 = 2.73%. Meta-regression repeated to assess the burn surface area again to be found noncontributing (p = 0.404). Conclusions: Our findings support that elevated NLR values can serve as a mortality indicator in burn cases. This will have a great clinical impact by aiding in stratifying the burn patients on admission. [ABSTRACT FROM AUTHOR]

Purpose: We aimed to investigate the impact of post-thrombectomy isolated subarachnoid hemorrhage (i-SAH) and other types of intracranial hemorrhage (o-ICH) on patient's neurological outcomes. Methods: Stroke data from 2018 to 2022 in a tertiary care center were retrospectively analyzed. Patients with large vessel occlusion from ICA to M2 branch were included. Post-thrombectomy intracranial hemorrhages at 24 h were categorized with Heidelberg Bleeding Classification. Neurological impairment of patients was continuously assessed at admission, at 24 h, 48 h and 72 h, and at discharge. Predictors of i-SAH and o-ICH were assessed. Results: 297 patients were included. i-SAH and o-ICH were found in 12.1% (36/297) and 11.4% (34/297) of patients. Overall, NIHSS of i-SAH patients at discharge were comparable to o-ICH patients (median 22 vs. 21, p = 0.889) and were significantly higher than in non-ICH patients (22 vs. 7, p < 0.001). i-SAH often resulted in abrupt deterioration of patient's neurological symptoms at 24 h after thrombectomy. Compared to non-ICH patients, the occurrence of i-SAH was frequently associated with worse neurological outcome at discharge (median NIHSS increase of 4 vs. decrease of 4, p < 0.001) and higher in-hospital mortality (41.7% vs. 23.8%, p = 0.022). Regardless of successful reperfusion (TICI 2b/3), the beneficial impact of thrombectomy appeared to be outweighed by the adverse effect of i-SAH. Incomplete reperfusion and shorter time from symptom onset to admission were associated with higher probability of i-SAH, whereas longer procedure time and lower baseline ASPECTS were predictive for o-ICH occurrence. Conclusion: Post-thrombectomy isolated subarachnoid hemorrhage is a common complication with significant negative impact on neurological outcome. [ABSTRACT FROM AUTHOR]

Purposes: Enterococcal BSI is associated with significant morbidity and mortality, with fatality rates of approximately 20–30%. There are microbiological and clinical differences between E. faecalis and E. faecium infections. The aim of this study was to investigate differences in predisposing factors for E. faecalis and E. faecium BSI and to explore prognostic factors. Methods: This study was a post-hoc analysis of PROBAC, a Spanish prospective, multicenter, cohort in 2016–2017. Patients with E. faecalis or E. faecium BSI were eligible. Independent predictors for BSI development in polymicrobial and monomicrobial BSI and in-hospital mortality in the monomicrobial group were identified by logistic regression. Results: A total of 431 patients were included. Independent factors associated with E. faecium BSI were previous use of penicillins (aOR 1.99 (95% CI 1.20–3.32)) or carbapenems (2.35 (1.12–4.93)), hospital-acquired BSI (2.58 (1.61–4.12)), and biliary tract source (3.36 (1.84–6.13)), while congestive heart failure (0.51 (0.27–0.97)), cerebrovascular disease (0.45 (0.21–0.98)), and urinary tract source (0.49 (0.26–0.92)) were associated with E. faecalis BSI. Independent prognostic factors for in-hospital mortality in E. faecalis BSI were Charlson Comorbidity Index (1.27 (1.08–1.51)), SOFA score (1.47 (1.24–1.73)), age (1.06 (1.02–1.10)), and urinary/biliary source (0.29 (0.09–0.90)). For E. faecium BSI, only SOFA score (1.34 (1.14–1.58) was associated with in-hospital mortality. Conclusions: The factors associated with E. faecium and E. faecalis BSI are different. These variables may be helpful in the suspicion of one or other species for empiric therapeutic decisions and provide valuable information on prognosis. [ABSTRACT FROM AUTHOR]

Purpose: Staphylococcus aureus prosthetic valve endocarditis (SAPVE) is a serious infection with high mortality. The main objective of this study was to identify factors associated with in-hospital mortality. Methods: From January 2008 to December 2021, consecutive patients from a Spanish cohort of infective endocarditis with a definitive diagnosis of SAPVE were analyzed. Results: During the study period, 219 cases of definitive SAPVE were diagnosed, which accounted for 16.7% of a total of 1309 cases of definitive prosthetic valve endocarditis (PVE). Patients presented advanced age and marked comorbidity. There was a higher incidence of persistent bacteremia, septic shock, stroke, and acute kidney injury than in cases of PVE caused by other microorganisms. Methicillin resistance was not associated with differences in clinical presentation, echocardiographic findings, or mortality. Only 50.6% of the patients with surgical indications (88 patients) underwent surgery. Overall, in-hospital mortality was 47.9%. The variables associated with in-hospital mortality were age (OR:1.03, 95% CI: 1.00-1.05; p = 0.016), heart failure (OR:2.86, 95% CI: 1.53–5.32; p = 0.001), acute kidney injury (OR:2.42, 95%CI:1.28–4.58; p = 0.006), stroke (OR:3.53, 95%CI:1.79–6.96; p < 0.001) and surgery indicated but not performed (OR:2.01, 95%CI:1.06–3.8; p = 0.030). On the other hand, the performance of surgery per se in patients with SAPVE, regardless of whether there was a surgical indication according to the guidelines, was not associated with a reduction in in-hospital mortality. Conclusions: SAPVE is characterized by high mortality, which is more marked in patients who present a surgical indication but do not undergo surgery. [ABSTRACT FROM AUTHOR]

Background: The objective of this study was to assess long-term outcome in patients with spontaneous intracerebral hemorrhage admitted to the intensive care unit. Methods: Mortality and Glasgow Outcome Scale, Barthel Index, and 5-level EQ-5D version (EQ-5D-5L) scores were analyzed in a multicenter cohort study of three Spanish hospitals (336 patients). Mortality was also analyzed in the Medical Information Mart for Intensive Care III (MIMIC-III) database. Results: The median (25th percentile-75th percentile) age was 62 (50–70) years, the median Glasgow Coma Score was 7 (4–11) points, and the median Acute Physiology and Chronic Health disease Classification System II (APACHE-II) score was 21 (15–26) points. Hospital mortality was 54.17%, mortality at 90 days was 56%, mortality at 1 year was 59.2%, and mortality at 5 years was 66.4%. In the Glasgow Outcome Scale, a normal or disabled self-sufficient situation was recorded in 21.5% of patients at 6 months, in 25.5% of patients after 1 year, and in 22.1% of patients after 5 years of follow-up (4.5% missing). The Barthel Index score of survivors improved over time: 50 (25–80) points at 6 months, 70 (35–95) points at 1 year, and 90 (40–100) points at 5 years (p < 0.001). Quality of life evaluated with the EQ-5D-5L at 1 year and 5 years indicated that greater than 50% of patients had no problems or slight problems in all items (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression). In the MIMIC-III study (N = 1354), hospital mortality was 31.83% and was 40.5% at 90 days and 56.2% after 5 years. Conclusions: In patients admitted to the intensive care unit with a diagnosis of nontraumatic intracerebral hemorrhage, hospital mortality up to 90 days after admission is very high. Between 90 days and 5 years after admission, mortality is not high. A large percentage of survivors presented a significant deficit in quality of life and functional status, although with progressive improvement over time. Five years after the hemorrhagic stroke, a survival of 30% was observed, with a good functional status seen in 20% of patients who had been admitted to the hospital. [ABSTRACT FROM AUTHOR]

Background: In the population of patients in the intensive care unit (ICU), most studies compared the use of atypical antipsychotics, such as quetiapine, with the use of traditional haloperidol in patients with delirium of various forms and etiologies. The role of such agents in patients with hyperactive delirium is not fully understood. This study compares the effectiveness of quetiapine with haloperidol in treating the hyperactive form of delirium in terms of their effects on the Delirium Rating Scale-Revised-98 (DRS-R-98), length of stay in the ICU, and mortality in critically ill patients. Methods: One hundred adult patients diagnosed with hyperactive delirium were randomly assigned to receive either oral quetiapine (25–50 mg/day) or haloperidol (1–2 mg/day). The response, defined as "a DRS-R-98 severity score reduction from baseline of 50% or more" and a DRS-R-98 severity score of 12 or less without relapse, was the primary outcome. Results: The mean age of all patients was 68 ± 6 years. The study population's overall response rate was 92%. Response rates for the two groups were remarkably equal (p = 0.609). Secondary outcomes were comparable in both groups, such as ICU mortality (p = 0.496), in-hospital mortality (p = 0.321), in-hospital stay (p = 0.310), and the need for mechanical ventilation (p > 0.99). But the quetiapine group showed a statistically reduced mean ICU stay (10.1 ± 2.0 vs. 11.7 ± 2.6 days, p = 0.018) and increased sleeping hours per night (p = 0.001). Conclusions: Quetiapine may be equally as effective as haloperidol in treating the symptoms of hyperactive delirium in critically ill patients, with no mortality benefit. [ABSTRACT FROM AUTHOR]

Background: Clinical pharmacists perform activities to optimise medicines use and prevent patient harm. Historically, clinical pharmacy quality indicators have measured individual activities not linked to patient outcomes. Aim: To determine the proportion of patients who receive a pharmaceutical care bundle (PCB) (consisting of a medication history, medication review, discharge medication list and medicines information on the discharge summary) as well as investigate the relationship between delivery of this PCB and patient outcomes. Method: Pharmaceutical care bundle activities were defined within state-wide (Queensland, Australia) clinical information systems and datasets were linked. An observational study using routinely recorded data was performed at ten participating sites for adult patients who had a non-same day hospital stay. The association between extent of PCB delivery and three patient outcomes were investigated: length of stay (LOS), unplanned readmission, and mortality. Results: In total 283,813 patient hospital stays were evaluated. The delivery of the PCB occurred in 26.9% of patients at the ten participating hospital sites, ranging from 0.6 to 61.2% across sites. Patients with a longer LOS were more likely to receive delivery of the complete PCB (P < 0.001). There was no correlation between PCB and hospital standardised mortality ratio (r = 0.03, p = 0.93). Higher rates of delivery of the PCB were associated with lower rates of unplanned readmission within 30 days (r = − 0.993, p < 0.001). Conclusion: A complete PCB was delivered to 26.9% of patients and was associated with a significantly lower rate of unplanned readmission within 30 days. [ABSTRACT FROM AUTHOR]

This study on the Lombardia Cardiac Arrest Registry (Lombardia CARe,) the most complete nationwide out-of-hospital cardiac arrest (OHCA) registry in Italy, aims at evaluating post-OHCA intra-hospital mortality risk according to patient's characteristics and emergency health service management (EMS), including level of care of first-admission hospital. Out of 12,581 patients included from 2015 to 2022, we considered 1382 OHCA patients admitted alive to hospital and survived more than 24 h. We estimated risk ratios (RRs) of intra-hospital mortality through log-binomial regression models adjusted by patients' and EMS characteristics. The study population consisted mainly of males (66.6%) most aged 60–69 years (24.7%) and 70–79 years (23.7%). Presenting rhythm was non-shockable in 49.9% of patients, EMS intervention time was less than 10 min for 30.3% of patients, and cardiopulmonary resuscitation (CPR) was performed for less than 15 min in 29.9%. Moreover, 61.6% of subjects (n = 852) died during hospital admission. Intra-hospital mortality is associated with non-shockable presenting rhythm (RR 1.27, 95% CI 1.19–1.35) and longer CPR time (RR 1.39, 95% CI 1.28–1.52 for 45 min or more). Patients who accessed to a secondary vs tertiary care hospital were more frequently older, with a non-shockable presenting rhythm and longer EMS intervention time. Non-shockable presenting rhythm accounts for 27% increased risk of intra-hospital death in OHCA patients, independently of first-access hospital level, thus demonstrating that patients' outcomes depend only by intrinsic OHCA characteristics and Health System's resources are utilised as efficiently as possible.

Background: This meta-analysis was conducted to compare the efficacy of ceftazidime-avibactam combination therapy with that of monotherapy in the treatment of carbapenem-resistant Gram-negative bacterial (CR-GNB). Methods: A literature search of PubMed, Embase, the Cochrane Library, and ClinicalTrials.gov was conducted until September 1, 2023. Only studies that compared CZA combination therapy with monotherapy for CR-GNB infections were included. Results: A total of 25 studies (23 retrospective observational studies and 2 prospective studies) involving 2676 patients were included. There was no significant difference in 30-day mortality between the study group receiving combination therapy and the control group receiving monotherapy (risk ratio [RR] 0.91; 95% confidence interval [CI] 0.71–1.18). In addition, no significant differences were observed between the study and the control group in terms of in-hospital mortality (RR 1.00; 95% CI 0.79–1.27), 14-day mortality (RR 1.54; 95% CI 0.24–9.91), 90-day mortality (RR 1.18; 95% CI 0.62–2.22), and clinical cure rate (RR 0.95; 95% CI 0.84–1.08). However, the combination group had a borderline higher microbiological eradication rate than the control group (RR 1.15; 95% CI 1.00–1.32). Conclusions: Compared to monotherapy, CZA combination therapy did not yield additional clinical benefits. However, combination therapy may be associated with favorable microbiological outcomes.

Background: Herpes simplex encephalitis (HSE) is a disease with unfavorable vital and functional prognoses. There are no recent epidemiological data on HSE at a national level using real-life databases, especially in France. This study aimed to report the incidence, the clinical characteristics and outcomes of the patients with HSE. Methods: We conducted a comprehensive retrospective cohort study on all patients hospitalized for HSE in France between 2015 and 2022 using national hospital discharge databases. Incidence, socio-demographic and clinical characteristics (including comorbidities, seizure, stays' features, intensive care supports) were described. The short- (first stay) and long-term (6-month) outcomes were reported, in terms of mortality and rehospitalizations. Results: 1425 HSE patients were included (median age 67 [54–77] years old, M/F sex ratio 1.07), giving a mean yearly hospital incidence of 2.3 [2.1–2.5] per 1,000,000 inhabitants. 51.2% of the patients were admitted in ICU (n = 730), of whom 59.0% were mechanically ventilated. The overall mortality during the first stay was 14.3% (n = 204), up to 17.9% for ICU patients. Within 6 months, among the survivors, 10.1% had at least one rehospitalization related to HSE. At 6 months, 16.5% of all patients had died (n = 235), 20.8% for ICU patients. Conclusion: In France, the incidence of hospitalizations for HSE was 2.3 per 1,000,000 inhabitants with more than half of the patients admitted in ICU and a 6-month in-hospital mortality about 16.5%. This real-life update on the characteristics and severe outcomes of the disease raises awareness among care practitioners, of the serious nature of the disease, and thus can lead to higher vigilance.

Background: The stress hyperglycemia ratio (SHR), adjusted for average glycemic status, is suggested for assessing actual blood glucose levels. Its link with adverse outcomes is known in certain populations, yet its impact on sepsis patients' prognosis is unclear. This study explores the association between SHR and mortality in sepsis. Methods: We included 13,199 sepsis patients in this study and categorized SHR into distinct groups. Additionally, we utilized restricted cubic spline analysis to evaluate the correlation between SHR as a continuous variable and mortality. The primary outcome was 1-year all-cause mortality. Logistic regression and Cox proportional hazards models were employed to assess the associations between the SHR and both in-hospital mortality and 1-year mortality, respectively. Results: Among the study participants, 4,690 (35.5%) patients died during the 1-year follow-up. After adjusting for confounding variables, we identified a U-shaped correlation between SHR and 1-year mortality. Using an SHR of 0.99 as the reference point, the hazard ratio for predicted 1-year mortality increased by 1.17 (95% CI 1.08 to 1.27) per standard deviation above 0.99, whereas each standard deviation increase predicted the hazard ratio of 0.52 (95% CI 0.39 to 0.69) below 0.99. Furthermore, we found that SHR could enhance the predictive performance of conventional severity scores. Conclusion: There exists a U shaped association between SHR and mortality in sepsis patients, where both low and high SHR values are associated with an increased risk of poor outcomes.

Purpose: Surgery is required in 20–50% of patients with infective endocarditis (IE). Frailty increases surgical risk; however, the prognostic implications of frailty in patients undergoing IE-related surgery remain poorly understood. We aimed to assess the association between frailty and all-cause mortality or rehospitalization after discharge (≥ 14 days). Methods: We identified all IE patients who underwent surgery during admission (2010–2020) in Denmark. The Hospital Frailty Risk Score was used to categorize patients into two frailty risk groups, patients with low frailty scores (< 5 points) and frail patients (≥ 5 points). We analyzed time hospitalized after discharge and all-cause mortality from the date of surgery with a one-year follow-up. Statistical analyses utilized the Kaplan–Meier estimator, Aalen–Johansen estimator, and the Cox regression model. Results: We identified 1282 patients who underwent surgery during admission, of whom 967 (75.4%) had low frailty scores, and 315 (24.6%) were frail. Frail patients were characterized by advanced age, a lower proportion of males, and a higher burden of comorbidities. Frail patients were more hospitalized (> 14 days) in the first post-discharge year (19.1% vs.12.3%) compared to patients with low frailty scores. Additionally, frail patients had higher rates of all-cause mortality including in-hospital deaths (27% vs. 15%) and rehospitalizations (43.5% vs 26.1%) compared to patients with low frailty scores. This was also evident in the adjusted analysis (hazard ratio 1.36 [CI 95% 1.09–1.71]). Conclusion: Frailty was associated with an ≈40% increased rate of rehospitalization (≥ 14 days) or death. Further studies are needed to assess the effectiveness of surgery with a focus on frailty to improve prognostic outcomes in these patients. [ABSTRACT FROM AUTHOR]

Background: Sepsis is a recognized global health challenge that places a considerable disease burden on countries. Although there has been some progress in the study of sepsis, the mortality rate of sepsis remains high. The relationship between serum osmolality and the prognosis of patients with sepsis is unclear. Method: Patients with sepsis who met the criteria in the Medical Information Mart for Intensive Care IV database were included in the study. Hazard ratios (HRs) and 95% confidence intervals (CIs) were determined using multivariable Cox regression. The relationship between serum osmolality and the 28-day mortality risk in patients with sepsis was investigated using curve fitting, and inflection points were calculated. Results: A total of 13,219 patients with sepsis were enrolled in the study; the mean age was 65.1 years, 56.9 % were male, and the 28-day mortality rate was 18.8 %. After adjusting for covariates, the risk of 28-day mortality was elevated by 99% (HR 1.99, 95%CI 1.74-2.28) in the highest quintile of serum osmolality (Q5 >303.21) and by 59% (HR 1.59, 95%CI 1.39-1.83) in the lowest quintile (Q1 ≤285.80), as compared to the reference quintile (Q3 291.38-296.29). The results of the curve fitting showed a U-shaped relationship between serum osmolality and the risk of 28-day mortality, with an inflection point of 286.9 mmol/L. Conclusion: There is a U-shaped relationship between serum osmolality and the 28-day mortality risk in patients with sepsis. Higher or lower serum osmolality is associated with an increased risk of mortality in patients with sepsis. Patients with sepsis have a lower risk of mortality when their osmolality is 285.80-296.29 mmol/L. [ABSTRACT FROM AUTHOR]

Purpose: Sepsis has a high incidence and a poor prognosis. Early recognition is important to facilitate timely initiation of adequate care. Sepsis screening tools, such as the (quick) Sequential Organ Failure Assessment ((q)SOFA) and National Early Warning Score (NEWS), could help recognize sepsis. These tools have been validated in a general immunocompetent population, while their performance in immunocompromised patients, who are particularly at risk of sepsis development, remains unknown. Methods: This study is a post hoc analysis of a prospective observational study performed at the emergency department. Inclusion criteria were age ≥ 18 years with a suspected infection, while ≥ two qSOFA and/or SOFA criteria were used to classify patients as having suspected sepsis. The primary outcome was in-hospital mortality. Results: 1516 patients, of which 40.5% used one or more immunosuppressives, were included. NEWS had a higher prognostic accuracy as compared to qSOFA for predicting poor outcome among immunocompromised sepsis patients. Of all tested immunosuppressives, high-dose glucocorticoid therapy was associated with a threefold increased risk of both in-hospital and 28-day mortality. Conclusion: In contrast to NEWS, qSOFA underestimates the risk of adverse outcome in patients using high-dose glucocorticoids. As a clinical consequence, to adequately assess the severity of illness among immunocompromised patients, health care professionals should best use the NEWS. [ABSTRACT FROM AUTHOR]

Iron deficiency (ID) is common in patients with acute myocardial infarction (AMI). It is unknown whether patients with AMI combined with ID will benefit from iron supplementation therapy. This study aimed to assess the relationship between iron therapy and mortality in AMI patients. Retrospective analysis was performed in subjects screened from the Medical Information Mart in Intensive Care-IV database. The data were obtained from ICU patients admitted to Beth Israel Deaconess Medical Center between 2008 and 2019. The patients were divided into two groups according to iron treatment exposure. Propensity score matching (PSM) was performed in the original cohort at a 1:1 ratio. Univariate and multivariate analyses were performed to adjust for confounding factors. The primary outcome was 28-day mortality. A total of 426 patients were included in this study. After 1:1 PSM, 208 patients were analyzed. Iron treatment was associated with a lower risk of 28-day mortality (9 deaths (8.65%) in the iron treatment group vs. 21 deaths (20.19%) in the non-iron treatment group; HR = 0.39; 95% CI = 0.17–0.89; p = 0.025) and in-hospital mortality (4 deaths (3.85%) in the iron treatment group vs. 12 deaths (11.54%) in the non-iron treatment group; OR, 0.15; 95% CI, 0.03–0.74; p = 0.029). Iron treatment was associated with reduced 28-day mortality in patients with AMI combined with ID. Iron treatment had no significant effect on the length of hospitalization or the length of ICU stay. Prospective studies are needed to verify this conclusion. [ABSTRACT FROM AUTHOR]

It is known that people who are immunocompromised or have a comorbidity are at an increased risk for acquiring COVID-19, having a longer duration of COVID-19 symptoms, and a greater likelihood of severe outcomes, including people living with HIV (PLHIV) (Centers for Disease Control and Prevention. (n.d.). Basics of covid-19. Centers for Disease Control and Prevention. Retrieved October 31. 2022, from https://www.cdc.gov/coronavirus/2019-ncov/your-health/about-covid-19/basics-covid-19.html). However, treatment for PLHIV can greatly reduce the amount of HIV in a person's blood, known as viral suppression. This study compared the outcome of COVID-associated hospitalization among virally suppressed and unsuppressed PLHIV in Colorado. A retrospective cohort analysis was conducted including all known PLHIV in Colorado that were diagnosed with COVID-19 between March 2020 and September 2022. Relevant covariates were identified including race/ethnicity, age at time of diagnosis, region of diagnosis, and vaccination status. An initial univariate logistic regression was then built to test the statistical significance of the association between viral suppression and hospitalization. The final model included all associated covariates and crude and adjusted odds ratios were analyzed. When controlling for covariates, PLHIV who were not virally suppressed at the time of their COVID-19 diagnosis were 2.5 (OR 2.5, 95% CI 1.6-4.0) times as likely to be hospitalized at the time of their first COVID-19 diagnosis compared to those that were suppressed. These findings suggest that viral suppression among PLHIV is protective against poor COVID-19 outcomes. This study is an important first step in highlighting the importance of PLHIV being retained in care and achieving viral suppression in reducing hospitalizations due to COVID-19 in Colorado.

Background: A wide variation of emergency medical system configurations across countries has limited the value of comparison of quality and performance measures in the past. Furthermore, lack of quantitative data on EDs prevents definition of the problems and possibilities for data driven improvement of quality of care. Therefore, the objective is to describe and compare Emergency Department (ED) populations and characteristics, and their outcomes in the Netherlands, Denmark and Australia, using a recently developed template for uniform reporting of standardized measuring and describing of care provided in the ED (structure, staffing and governance, population, process times and outcomes). Methods: This international multicenter cohort included all consecutive ED visits from National Quality Registries or Databases from participating sites from three countries. Patient and ED characteristics (using the template for uniform reporting) and relevant clinical outcomes were described and compared per country. Results: We included 212,515 ED visits in the Netherlands, 408,673 in Denmark and 556,652 in Australia. Patient characteristics differed markedly, with Australian ED patients being younger, less often triaged as "immediate", and less often triaged with the high-risk chief complaints "feeling unwell" compared to Danish and Dutch patients. ED characteristics mainly differed with respect to the mean annual census per ED (Netherlands 26,738 (SD 2630), Denmark 36,675 (SD 12974), Australia 50,712 (4884)), median (IQR) lengths of stay of patients discharged home (Netherlands 2.1 (1.4–3.1); Denmark 2.8 (1.7–5.0); Australia 3.3 (2.0–5.0) hrs) and proportion of hospitalizations (ranging from 30.6 to 39.8%). In-hospital mortality was 4.0% in Australia, higher compared to the Netherlands and Denmark (both 1.6%). Not all indicators of the framework were available in all registries. Conclusions: Patient and ED characteristics and outcomes varied largely across countries. Meaningful interpretation of outcome differences across countries could be improved if quality registries would more consistently register the measures of the recently developed template for uniform reporting.

This study addresses the relationship between platelet count and 30-day in-hospital mortality in End-Stage Kidney Disease (ESRD) patients in the intensive care unit (ICU), a topic with limited existing evidence. Utilizing data from the US eICU-CRD v2.0 database (2014–2015), a retrospective cohort study was conducted involving 3700 ICU ESRD patients. We employed binary logistic regression, smooth curve fitting, and subgroup analyses to explore the association between platelet count and 30-day in-hospital mortality. The 30-day in-hospital mortality rate was 13.27% (491/3700), with a median platelet count of 188 × 109/L. After adjusting for covariates, we observed a relationship between platelet count and 30-day in-hospital mortality (OR = 0.98, 95% CI 0.97, 0.99). Subgroup analyses supported these findings. More importantly, a nonlinear association was detected, with an inflection point at 222 × 109/L. The effect sizes (OR) on the left and right sides of the inflection point were 0.94 (0.92, 0.96) and 1.03 (1.00, 1.05), respectively. The most significant finding of this study is the revelation of a nonlinear relationship between baseline platelet count and 30-day in-hospital mortality in ICU patients with ESRD. This discovery explicitly suggests that when ESRD patients are admitted to the ICU, a platelet level closer to 222 × 10⁹/L may predict a lower 30-day in-hospital mortality risk.

Background: The micro-axial flow pump Impella, a new mechanical circulatory device for cardiogenic shock, is still only available in a limited number of hospitals, due to the facility certification requirements and insufficient evidence of the benefit of introducing Impella in hospitals. This study aimed to evaluate the impact of introducing Impella in hospitals on in-hospital mortality of patients treated with extracorporeal membrane oxygenation (ECMO). Methods: Using a nationwide Japanese inpatient database, we identified patients who received ECMO during hospitalization between 1 April 2014 and 31 March 2021. A hospital-level propensity score–matched cohort was created matching hospitals that introduced Impella (exposure group) to those that did not introduce Impella (control group). The inclusion period in each hospital was divided into two time periods according to the time of Impella introduction in the exposure group and the corresponding hospital in the control group (before and after exposure). The primary outcome was in-hospital mortality. Uncontrolled and controlled interrupted time-series analyses involved before–after exposure comparison and exposure–control comparison. Results: Out of 34,379 eligible patients, we created a matched cohort of 8351 patients from 86 hospitals with Impella introduction (exposure group) and 7230 patients from 86 hospitals without Impella introduction (control group). In-hospital mortality before and after exposure was 62.5% and 59.3, respectively, in the exposure group; and 66.8% and 63.7%, respectively, in the control group. Uncontrolled interrupted time-series analysis showed no significant level change or trend change in the before–after exposure comparison in both the exposure and the control groups. Controlled interrupted time-series analysis also showed no significant level change (−0.01%; 95% confidence intervals −5.36% to + 5.33%) or trend change (+ 0.10%, −0.30% to + 0.40%) after exposure in the exposure–control comparison. Conclusions: This nationwide inpatient database study showed no association between Impella introduction in hospitals and in-hospital mortality of patients who underwent ECMO. Because this study confined itself to analze of the impact of the introduction of Impella solely at the hospital level, further detailed studies are warranted to assess its efficacy at the patient level.

The American Society of Anesthesiologist's Physical Status (ASA-PS) classification system assesses comorbidities before sedation and analgesia, but inconsistencies among raters have hindered its objective use. This study aimed to develop natural language processing (NLP) models to classify ASA-PS using pre-anesthesia evaluation summaries, comparing their performance to human physicians. Data from 717,389 surgical cases in a tertiary hospital (October 2004–May 2023) was split into training, tuning, and test datasets. Board-certified anesthesiologists created reference labels for tuning and test datasets. The NLP models, including ClinicalBigBird, BioClinicalBERT, and Generative Pretrained Transformer 4, were validated against anesthesiologists. The ClinicalBigBird model achieved an area under the receiver operating characteristic curve of 0.915. It outperformed board-certified anesthesiologists with a specificity of 0.901 vs. 0.897, precision of 0.732 vs. 0.715, and F1-score of 0.716 vs. 0.713 (all p <0.01). This approach will facilitate automatic and objective ASA-PS classification, thereby streamlining the clinical workflow. [ABSTRACT FROM AUTHOR]

Integrating modern machine learning and clinical decision-making has great promise for mitigating healthcare's increasing cost and complexity. We introduce the Enhanced Transformer for Health Outcome Simulation (ETHOS), a novel application of the transformer deep-learning architecture for analyzing high-dimensional, heterogeneous, and episodic health data. ETHOS is trained using Patient Health Timelines (PHTs)—detailed, tokenized records of health events—to predict future health trajectories, leveraging a zero-shot learning approach. ETHOS represents a significant advancement in foundation model development for healthcare analytics, eliminating the need for labeled data and model fine-tuning. Its ability to simulate various treatment pathways and consider patient-specific factors positions ETHOS as a tool for care optimization and addressing biases in healthcare delivery. Future developments will expand ETHOS' capabilities to incorporate a wider range of data types and data sources. Our work demonstrates a pathway toward accelerated AI development and deployment in healthcare. [ABSTRACT FROM AUTHOR]

This study delves into the correlation between the triglyceride glucose-body mass index (TyG-BMI) index upon hospital admission and clinical outcomes among this patient population. We investigated the association between TyG-BMI at hospital admission and clinical outcomes in this patient group, and analyzed data from the Medical Information Mart for Intensive Care IV database, identifying acute pancreatitis (AP) patients admitted to ICUs and stratifying them by TyG-BMI quartiles. We assessed the relationship between TyG-BMI and mortality (both in-hospital and ICU) using Cox proportional hazards regression and restricted cubic splines. The cohort included 419 patients, average age 56.34 ± 16.62 years, with a majority being male (61.58%). Hospital and ICU mortality rates were 11.93% and 7.16%, respectively. Higher TyG-BMI was positively correlated with increased all-cause mortality. Patients in the highest TyG-BMI quartile had significantly greater risks of in-hospital and ICU mortality. An S-shaped curve in the spline analysis indicated a threshold effect at a TyG-BMI of 243 for increased in-hospital mortality risk. TyG-BMI is a reliable predictor of both in-hospital and ICU mortality in severely ill AP patients, suggesting its utility in enhancing risk assessment and guiding clinical interventions for this vulnerable population.

To investigate if retinal thickness has predictive utility in COVID-19 outcomes by evaluating the statistical association between retinal thickness using OCT and of COVID-19-related mortality. Secondary outcomes included associations between retinal thickness and length of stay (LoS) in hospital. In this retrospective cohort study, OCT scans from 230 COVID-19 patients admitted to the Intensive Care Unit (ITU) were compared with age and gender-matched patients with pneumonia from before March 2020. Total retinal, GCL + IPL, and RNFL thicknesses were recorded, and analysed with systemic measures collected at the time of admission and mortality outcomes, using linear regression models, Pearson's R correlation, and Principal Component Analysis. Retinal thickness was significantly associated with all-time mortality on follow up in the COVID-19 group (p = 0.015), but not 28-day mortality (p = 0.151). Retinal and GCL + IPL layer thicknesses were both significantly associated with LoS in hospital for COVID-19 patients (p = 0.006 for both), but not for patients with pneumonia (p = 0.706 and 0.989 respectively). RNFL thickness was not associated with LoS in either group (COVID-19 p = 0.097, pneumonia p = 0.692). Retinal thickness associated with LoS in hospital and long-term mortality in COVID-19 patients, suggesting that retinal structure could be a surrogate marker for frailty and predictor of disease severity in this group of patients, but not in patients with pneumonia from other causes.

Purpose: The necessity of routine drain placement in pancreatic resections is controversial. Some randomized controlled trials have shown that the omission of drainage is safe for some patients, whereas reintervention rates and mortality rates are substantial for others. The present study aimed to assess fistula-associated outcomes in the setting of routine drain placement and drain irrigation on demand. Methods: Between 01/2017 and 12/2022, perioperative and outcome data from patients who underwent consecutive pancreatoduodenectomies (PD, n = 253) or distal pancreatectomies (DP, n = 72) were prospectively collected in the electronic StuDoQ database and analysed. All patients underwent intraoperative drain placement. Drains were removed starting at postoperative day 2 in PD or at day 5 in DP after testing for amylase concentration. In case of high amylase levels or macroscopically suspicious pancreatic fistulas, drain irrigation was started. Nondrained fluid collections underwent percutaneous radiologic or transluminal endoscopic evacuation. Results: Clinically relevant pancreatic fistulas were detected in 53 of 325 patients (POPF grade B 16.3%, grade C 1.2%). 43.3% of those had drain irrigation. Additional interventional or endoscopic drainage was necessary in 14 and 5 patients, respectively (overall 5.8%), and were observed in 4.0% of patients with PD and in 12.5% with DP (p = 0.009). Delayed fistula-associated postpancreatectomy haemorrhage (PPH) was present in 1.2% (4/325) of patients. The fistula- and delayed PPH-associated reoperation rate was 1.5% (5/325). The 30-day and in-hospital mortality rates were both 1.5% (5/325), and the rate of fistula-associated mortality was 0.6% (2/325). The overall 90-day mortality rate was 4.5%. Conclusions: In pancreatectomies, a standardized drainage protocol including on-demand drain irrigation results in very low fistula-associated morbidity and mortality and an infrequent need for interventional or surgical reintervention as compared to previously published drainage studies.

Background: Status epilepticus (SE) is a heterogeneous neurological emergency with significant variability in prognosis, influenced by underlying disease and pathophysiological context. Acid–base disturbances are common in critically ill patients, yet their distribution and impact in SE patients remain poorly understood. Methods: This was an observational cohort study including non-hypoxic SE patients with available blood gas analysis within the first 24 h of SE, treated at the University Hospital of Geneva, Switzerland between 2015 and 2023. Acid–base disturbances were classified using the Henderson–Hasselbalch equation, with prevalent metabolic alkalosis confirmed through the Stewart approach. Primary outcomes were in-hospital mortality, Glasgow Outcome Scale (GOS) at discharge, and return to premorbid neurologic function. Findings: Among 540 SE patients, 365 were included. Half of patients exhibited acid–base disturbances within the initial 24 h of SE, with metabolic and respiratory acidosis being the most prevalent, though not prognostically significant. After correction for possible confounders, metabolic alkalosis (6%) was associated with increased in-hospital mortality (P = 0.011; OR = 4.87, 95% CI = 1.29–7.84), worse GOS (P = 0.012; OR = 3.18, 95% CI = 1.29–7.84), and reduced likelihood of returning to premorbid function (P = 0.017; OR = 3.30, CI95% = 1.24–8.80). Following the Stewart approach, 9% of patients had predominant metabolic alkalosis, associated with worse GOS (P = 0.005; OR:3.37, 95%CI = 1.45–7.82), and reduced chance of returning to baseline (P = 0.012; OR = 3.29, CI95% = 1.30–8.32). Metabolic alkalosis was related to hypoalbuminemia and lower serum potassium. Conclusion: Metabolic alkalosis strongly predicts mortality and adverse functional outcome in SE patients. Prospective studies should assess whether early detection and correction of metabolic alkalosis and related electrolyte imbalances can improve SE prognosis. [ABSTRACT FROM AUTHOR]

Objectives: Severe thrombotic antiphospholipid syndrome (APS) frequently affects the kidney, heart, and central nervous system. The precise frequency, clinical picture, differential diagnoses, and outcome of APS-related hematological involvement are lacking, especially in patients requiring ICU admission. This study aimed to describe the hematological manifestations associated with critically ill thrombotic APS patients and catastrophic antiphospholipid syndrome. Methods: This French, national, multicenter, retrospective study, conducted, from January 2000 to September 2018, included all APS patients admitted to 24 participating centers' ICUs with any new thrombotic manifestation. The prevalence of hematological manifestations and their associated outcomes were studied. Results: One hundred and thirty-four patients, female 72%, median [IQR] age 45 [34–56] years, with 152 episodes were included. Anemia was present in 95% of episodes and thrombocytopenia in 93%. The lowest values for hemoglobin and platelets were 7.1 [6.3–8.8] g/dL and 38 [21–60] g/L, respectively. The lowest platelet count below 20 g/L was significantly associated with a higher in-ICU mortality rate (50%, p < 0.0001). A thrombotic microangiopathy syndrome (TMA) syndrome was seen in 16 patients (12%) and was associated with higher in-hospital mortality (p = 0.05). Median ADAMTS-13 levels were 44% [27–74]. Anti-ADAMTS13 antibodies were tested in 11 patients and found negative in all. A suspicion of heparin-induced thrombocytopenia (HIT) was raised in 66 patients but only four patients were classified as definite HIT. Disseminated intravascular coagulation (DIC) was seen in 51% of patients. Conclusion: Thrombocytopenia is very frequent in severe APS patients and may be related to TMA, HIT, or DIC. Deciphering the mechanisms of thrombocytopenia is decisive in CAPS patients. Key Points • Thrombocytopenia is the hallmark laboratory finding in CAPS. • A complete thrombotic microangiopathy pattern is infrequent in CAPS patients. • Alternate diagnoses of CAPS, especially heparin-induced thrombocytopenia, need to be adequately investigated.
