Objective: Auxiliary nephrolithometric scoring systems (NSSs) have been developed to predict complications and treatment success of conventional percutaneous nephrolithotomy (PCNL). However, to our knowledge, there is no study comparing these NSSs in patients undergoing miniPCNL. This study aimed to compare the NSSs in terms of their ability to predict miniPCNL-related complications and treatment success. Methods: The data of patients undergoing PCNL between September 2016 and May 2018 were retrospectively reviewed through the electronic medical record system, and 140 patients were included in our study. Stone-free status was evaluated using non-contrast computed tomography between 1 and 3 months after the procedure. PCNL was considered successful if the patient was completely stone free. The postsurgical complications were classified according to the modified Clavien–Dindo classification system. Results: The Clinical Research Office of the Endourological Society (CROES) and STONE NSSs significantly predicted miniPCNL treatment success (p = 0.043, p = 0.018). However, the Guy's NSS did not significantly predict the treatment success (p = 0.415). Guy's, CROES and STONE NSSs were not found to significantly predict postsurgical complications (p = 0.584, p = 0.823, p = 0.189). Conclusion: To the best of our knowledge, our study is the first of its kind to investigate the ability of NSSs to predict treatment success and postsurgical complications in patients undergoing miniPCNL. The study found that STONE and CROES NSSs are independent parameters for predicting stone-free status after miniPCNL. In addition, our study found that none of the NSSs were useful in predicting postsurgical complications in patients undergoing miniPCNL. [ABSTRACT FROM AUTHOR]

PADUA, RENAL, ABC and MAP nephrometry scores were determined from preoperative axial images. Unadjusted and adjusted associations between overall scores, individual components, surgical approach, complications and oncological outcomes were determined using univariate and multivariate logistic regressions.Results: A total of 189 partial nephrectomies were performed in 181 patients, via an open or a laparoscopic approach. Among scoring systems, only the MAP classification, which assesses adherent perinephric fat, was associated with severe surgical complications as well as with operative time (p< 0.05). Among all components of the PADUA and RENAL scores, only proximity of the tumor to the collecting system was associated with overall surgical complication rates, while the diameter of the tumor influenced the operative time (p< 0.05). The ABC score was not relevant. Male gender, antiplatelet therapy, and a laparoscopic approach were associated with higher overall surgical complication rates (p< 0.05). The number of oncologic recurrences during follow-up was too low to run statistical analyses.Conclusion: Nephrometry scores could be simplified to predict surgical complications after partial nephrectomy. In this framework, adherent perinephric fat seemed to be strongly associated with an increased risk of surgical complications.Keywords: partial nephrectomy, scoring systems, perinephric fat, laparoscopy, complications

BACKGROUND: Acute appendicitis is one of the most common causes of emergency department (ED) admission among pediatric patients, and the most common cause of abdominal pain requiring surgical intervention. The present study aimed to measure the success of three different appendicitis scoring systems in patients who were operated due to acute appendicitis (AA) upon presenting at the pediatric ED with acute abdominal pain. METHODS: The study included a total of 226 patients who were admitted to Pediatric Emergency Department and who underwent an appendectomy between December 2018 and May 2019. Through a retrospective review of patient files; age, gender, clinical findings, laboratory results, Pediatric Appendicitis Score (PAS), Lintula score, Acute Inflammatory Response (AIR) score, ultrasonography (USG) findings and pathology results of the patients operated due to AA were recorded. RESULTS: A total of 226 patients were included in the study, with a mean age of 11.6±3.66 (1-17) years, and 57.1% (n=129) of the patients were female and 42.9% (n=97) were male. The pathology results were evaluated under three categories: suppurative (phlegmonous) appendicitis, 74.3%; perforated appendix, 9.7%; and reactive lymphoid hyperplasia, 15.9%. The cut-off values gt;3 for AIR, gt;7 for PAS and gt;15 for Lintula were found statistically significant. Among the three scoring systems, Lintula had the highest sensitivity (91.5%) and PAS had the highest specificity (69.4%). DISCUSSION:Although scoring systems are used to diagnose AA, the selected cut-off values for the scoring systems have an effect on the results.. Patients with a PAS score of ≥7 were found to have more significant AA results. We believe that PAS is likely to be a preferred scoring system in pediatric patients, especially under busy ED conditions; however, further studies with larger populations are needed to develop scoring systems that will guide physicians to establish a final diagnosis.

Introduction Numerous scoring systems have been created to predict the risk of morbidity and mortality in patients undergoing emergency general surgery (EGS). In this article, we compared the different scoring systems utilized at Humanitas Research Hospital and analyzed which one performed the best when assessing geriatric patients (>65 years of age). The scoring systems that were utilized were the APACHE II (Acute Physiology and Chronic Health Evaluation II), ASA (American Society of Anesthesiologists), ACS-NSQIP (American College of Surgeons-National Surgical Quality Improvement Program), Clinical Frailty Score, and the Clavien–Dindo classification as control. Materials and Methods We compiled a database consisting of all patients over the age of 65 who underwent EGS in a consecutive 24-month period between January 1, 2017 and December 31, 2018. We used the biostatistical program “Stata Version 15” to analyze our results. Results We found 213 patients who matched our inclusion criteria. Regarding death, we found that the ACS-NSQIP death calculator performed the best with an area under the curve of 0.9017 (odds ratio: 1.09; 95% confidence interval: 1.06–1.12). The APACHE II score had the lowest discriminator when predicting death. Considering short-term complications, the Clavien–Dindo classification scored highly, while both the APACHE II score and Clinical Frailty Score produced the lowest results. Conclusion The results obtained from our research showed that scoring systems and classifications produced different results depending on whether they were used to predict deaths or short-term complications among geriatric patients undergoing EGS.

Forty-eight patients (96%) were Black or African American. Glasgow Coma Scale was available for all 50 patients at T0. Vital signs, except for temperature, were readily available (> 90%) at T0. The majority of laboratory values relevant for sepsis scoring criteria were available (> 90%) at T1, with exception to bilirubin (66%) and creatinine (80%). NEWS, PRESEP and qSOFA had greater than 90% criteria availability at triage. SOFA and SIRS consistently had the least percent of available criteria at all time points in the ED.Conclusion: The availability of patient data at different time points in a patient’s ED visit suggests that different scoring methods could be utilized to assess for sepsis as more patient information becomes available.Keywords: sepsis, scoring systems, available criteria, emergency department, patient safety, quality improvement

Background and Objectives: The aim of this study is to compare the performance of six clinical physiological-based scores, including the pre-endoscopy Rockall score, shock index (SI), age shock index (age SI), Rapid Acute Physiology Score (RAPS), Rapid Emergency Medicine Score (REMS), and Modified Early Warning Score (MEWS), in predicting in-hospital mortality in elderly and very elderly patients in the emergency department (ED) with acute upper gastrointestinal bleeding (AUGIB). Materials and Methods: Patients older than 65 years who visited the ED with a clinical diagnosis of AUGIB were enrolled prospectively from July 2016 to July 2021. The six scores were calculated and compared with in-hospital mortality. Results: A total of 336 patients were recruited, of whom 40 died. There is a significant difference between the patients in the mortality group and survival group in terms of the six scoring systems. MEWS had the highest area under the curve (AUC) value (0.82). A subgroup analysis was performed for a total of 180 very elderly patients (i.e., older than 75 years), of whom 27 died. MEWS also had the best predictive performance in this subgroup (AUC, 0.82). Conclusions: This simple, rapid, and obtainable-by-the-bed parameter could assist emergency physicians in risk stratification and decision making for this vulnerable group.

Surgery is the first-line therapy for most benign and malignant skull base tumors. Extent of resection (EOR) is a metric commonly used for preoperative surgical planning and to predict risk of postoperative tumor recurrence. Therefore, understanding the evidence on EOR in skull base neurosurgery is essential to providing optimal care for each patient. Several studies from the skull base neurosurgery literature have presented investigations of various topics related to EOR, including 1) preoperative EOR scoring systems, 2) intraoperative EOR scoring systems, 3) EOR and tumor recurrence, and 4) EOR and functional outcomes. We propose that future investigations should focus on the following elements to improve EOR research in skull base neurosurgery: 1) multi-institutional collaboratives with treatment propensity matching; 2) expert consensus and mixed-methods study design; and 3) predictive analytics/machine learning. We believe that these methods offer several advantages that have been described in the literature and that they address limitations of previous studies. The aim of this review was to inform future study design and improve the overall quality of subsequent investigations on EOR in skull base neurosurgery. [ABSTRACT FROM AUTHOR]

This article conducts a contemporary comparative review of the medical literature to update and establish evidence as to which framework among Rotterdam and Marshall computed tomography (CT)-based scoring systems predicts traumatic brain injury (TBI) outcomes better. The scheme followed was following the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines for literature search. The search started on August 15, 2020 and ended on December 31, 2020. The combination terms used were Medical Subject Headings terms, combination keywords, and specific words used for describing various pathologies of TBI to identify the most relevant article in each database. PICO question to guide the search strategy was: “what is the use of Marshall (I) versus Rotterdam score (C) in TBI patients (P) for mortality risk stratification (O).” The review is based on 46 references which included a full review of 14 articles for adult TBI patients and 6 articles for pediatric TBI articles comparing Rotterdam and Marshall CT scores. The review includes 8,243 patients, of which 2,365 were pediatric and 5,878 were adult TBI patients. Marshall CT classification is not ordinal, is more descriptive, has better inter-rater reliability, and poor performance in a specific group of TBI patients requiring decompressive craniectomy. Rotterdam CT classification is ordinal, has better discriminatory power, and a better description of the dynamics of intracranial changes. The two scoring systems are complimentary. A combination of clinical parameters, severity, ischemic and hemodynamic parameters, and CT scoring system could predict the prognosis of TBI patients with significant accuracy. None of the classifications has good evidence for use in pediatric patients. [ABSTRACT FROM AUTHOR]

Objective The aim was to evaluate the performance of thorax trauma severity score (TTSS) in predicting hospital mortality in thoracic trauma and comparing its performance with the trauma and injury severity score (TRISS). Background Because the great risk of thoracic trauma that may be life-threatening especially if uncontrolled, early management of it reduces mortality of polytraumatized patients. TTSS and TRISS were developed for the purpose of prediction of hospital mortality in thoracic trauma. Patients and methods This is a prospective comparative study done on 100 patients with chest trauma, either isolated chest trauma or as a part of polytrauma, who presented to the Emergency Department of Menoufia University Hospital during the period from April 2019 to April 2020. TTSS score was applied to assess its performance and comparing it with TRISS score. Results TTSS and TRISS scores were applied on 100 patients with trauma meeting inclusion criteria to predict the hospital mortality in thoracic trauma. The area under the receiver operating characteristics curve was 0.88 for TTSS score and 0.892 for TRISS score. Conclusion This study demonstrates that the TRISS, and the TTSS, can be used to predict hospital mortality in patients with thoracic trauma; hence, additional prospective studies are required. We believe that the study provides important information regarding validation of the TTSS, as it had a direct correlation with need for oxygenation, ventilator, duration of hospital stay, mortality, or outcome in patients with chest trauma.

Predicting severity of acute pancreatitis enables optimization of care, reducing morbidity and length of stay. Modified adult scoring systems have not been able to adequately predict severity in children. This was a retrospective study of children presenting with a first episode of acute pancreatitis from 2002 to 2020 in a single tertiary paediatric surgical centre. Serum markers including CRP at 48 h of admission were analysed. Promising biomarkers underwent ROC (Receiver Operating Curve) analysis, and these were compared to the modified Glasgow Pancreas Score. An AUC (Area Under Curve) > 0.90 was taken as an excellent predictor of severity. Data of 59 children were analysed, median age 13 years. 22 patients (37%) had a severe episode. ROC analysis demonstrated CRP as the best predictor of severity giving an AUC of 0.92. Optimum cut off value for CRP was 107.5 mg/L (p < 0.0001) producing sensitivity of 91%, specificity of 84%. This was superior to the modified Glasgow Pancreas score, which produced a sensitivity of 36% and specificity of 100%. We have shown that a CRP value of > 108 mg/L within 48 h of admission can be used to predict severity of acute pancreatitis in children with greater accuracy than current scoring systems.

Innumerable scoring systems have been introduced to measure the disease severity of various dermatological conditions. The development of such scores has proved to be beneficial to assess disease progression and treatment effectiveness in the context of dermatological research. However, these scoring systems tend to be time consuming, monotonous, and hence often difficult to use during overburdened routine clinical consultations, especially when it is in the form of a paper-based system. Many of the scoring systems are now available in the digital form, such as smart phone apps. This aids to calculate effortlessly and reduces human errors associated with paper-based formats. Various calculators like Psoriasis Area Severity Index calculators, Severity Scoring Of Atopic Dermatitis, and Melasma Area Severity Index have been introduced in the digital format for a quicker, efficient quality of work and uncomplicated data storage. This review highlights and discusses some of the digital tools available at present for severity scoring in dermatology. [ABSTRACT FROM AUTHOR]

ABSTRACTBackground: Identification of tissue hypoxia and hypoperfusion plays an important role in the management of critically ill patients. Although the venous-arterial PCO2 difference (ΔPCO2) cannot serve as a marker of tissue hypoxia, it is considered a marker of the adequacy of venous blood flow (Cardiac output). The present study aimed to evaluate the role of venous-arterial PCO2 gradient in prediction of outcome in septic patients admitted to ICU.Patients and methods: 100 adult patients fulfilled the criteria of severe sepsis or septic shock admitted to Emergency Intensive Care Unit, were divided in two groups according to ΔPCO2. The high ΔpCO2 group (ΔpCO2 > 6 mmHg) included 58 patients and the normal ΔpCO2 (ΔpCO2 ≤ 6 mmHg) included 42 patients. Clinical scoring systems were recorded. Clinical outcome including organ dysfunction and mortality was recorded.Results: The high ΔPCO2 group showed significant lower blood glucose level (p = 0.038) than the normal ΔPCO2 group. Serum lactate, heart rate, and APACHE score were significantly higher in high ΔPCO2 group than normal ΔPCO2 group (p, 0.012, 0.013, and 0.020, respectively). As regard to the clinical outcome, patient mortality was significantly higher (p = 0.042) in high ΔPCO2 group than normal ΔPCO2 group and the number of organ dysfunction was higher in high ΔPCO2 group than normal ΔPCO2 group but not reached a significant level (p = 0.625).Conclusions: ΔPCO2 is a reliable index for early prediction of clinical outcome including organ dysfunction and mortality in patients with sepsis and septic shock.

Objective: To evaluate the performance of the Quick COVID-19 Severity Index (qCSI) and the Brescia-COVID Respiratory Severity Scale (BCRSS) in predicting intensive care unit (ICU) admissions and in-hospital mortality in patients with coronavirus disease 2019 (COVID-19) pneumonia. Methods: This was a retrospective cohort study of 313 consecutive hospitalized adult patients (18 years or older) with confirmed COVID-19. The area under the receiver operating characteristic curve (AUC) was used to assess the discriminatory power of the qCSI score and BCRSS prediction rule compared to the CURB-65 score for predicting mortality and intensive care unit admission. Results: The overall in-hospital fatality rate was 32.3%, and the ICU admission rate was 31.3%. The CURB-65 score had the highest numerical AUC to predict in-hospital mortality (AUC 0.781) compared to the qCSI score (AUC 0.711) and the BCRSS prediction rule (AUC 0.663). For ICU admission, the qCSI score had the highest numerical AUC (AUC 0.761) compared to the BCRSS prediction rule (AUC 0.735) and the CURB-65 score (AUC 0.629). Conclusions: The CURB-65 and qCSI scoring systems showed a good performance for predicting in-hospital mortality. The qCSI score and the BCRSS prediction rule showed a good performance for predicting ICU admission.

Introduction. The infection with Mycobacterium tuberculosis represents a common cause of pleural effusions, and its diagnosis poses difficulties for clinicians. In the attempt to facilitate a quick, accurate and inexpensive diagnosis, the research is focused on evaluating useful biomarkers in the pleural fluid. Adenosine deaminase (ADA) level in the pleural fluid is a biomarker with high specificity and sensitivity for the diagnosis. The objective of the study was to assess the association between ADA levels in the pleural fluid, other pleural fluid characteristics, and clinical aspects in tuberculous pleurisy. Material and methods. We performed a retrospective study on 77 patients diagnosed with tuberculous pleurisy (positive Mycobacterium tuberculosis cultures in the pleural fluid or biopsy specimens and/or specific histological aspect: epithelioid granuloma with caseous necrosis in pleural biopsy), between 2011-2018, in The National Institute of Pneumology “Marius Nasta” Bucharest, Romania. Results. The ADA values were positively and statistically significant correlated with lactate dehydrogenase (LDH) and protein levels in the pleural fluid. Also, the mean ADA value was increased in febrile patients as compared with the afebrile ones, statistically significant (p

BACKGROUND: In our study, it was aimed to find out whether it would be possible to determine the disease severity by comparing the values of red cell distribution width (RDW), c-reactive protein (CRP), CRP/albumin, neutrophil/lymphocyte ratio (NLR), and platelet/lymphocyte ratio (PLR) in patients with acute pancreatitis according to Bedside Index of Severity in Acute Pancreatitis (BISAP) scores at the time of admission. METHODS: Five hundred patients diagnosed with acute pancreatitis were included in the study. RESULTS: According to BISAP scores, 388 (77.6 %) patients were evaluated as having mild acute pancreatitis and 112 (22.4 %) patients as having severe acute pancreatitis. In ROC analysis, values of 70.54 % sensitivity and 70.10 % specificity for CRP, 71.43 % sensitivity and 70.88 % specificity for CRP/albumin, 80.36 % sensitivity and 30.30 % specificity for RDW, 75.00 % sensitivity and 43.98 % specificity for NLR, and 55.36 % sensitivity and 38.51 % specificity for PLR were determined. Values of 85.71 % sensitivity and 66.49 % specificity were determined for the NLR-CRP/Albumin-RDW 2** score as a newly created scoring system. CONCLUSION: CRP/albumin, NLR, PLR, and RDW values were found to be statistically significantly higher in patients with severe acute pancreatitis compared to those with mild acute pancreatitis according to the BISAP score (p<0.001). In comparison to previous studies in the literature, similar sensitivity and specificity values were obtained in determining the severity of the disease with the new NLR-CRP/Albumin-RDW 2** score, and it is thought that this scoring system could be a practical and reliable guide in the treatment and follow-up of patients with acute pancreatitis (Tab. 6, Fig. 3, Ref. 22). ms [ABSTRACT FROM AUTHOR]

Introduction: Blunt chest trauma contributes to a significant number of trauma admissions globally and is the leading cause of morbidity and mortality. Although numerous scoring systems and risk factors for prognosticating blunt chest trauma have already been developed, we are still lacking a gold standard in this field. Aim: This study was conducted to reassess the significance of available scoring systems and other indicators of severity in prognosticating blunt chest trauma. Materials and methods: This prospective observational study analyzed 50 patients over 12 years of age who suffered a blunt chest trauma and required hospitalization in the period between November 2016 and March 2018. the following nine risk factors were assessed: age of the patient, time of presentation after injury, number of ribs fractured, presence of bilateral thoracic trauma, evidence of pulmonary contusion, associated extra-thoracic injuries, the need for mechanical ventilation, as well as the results of Revised Trauma Score (RTS) and Modified Early Warning Sign Score (MEWS). the severity of blunt thoracic trauma was divided into three categories - SIRS, ARDS and death. Data was analyzed with the use of statistical software package SPSS v22.0. Results: The age of 50 patients included in our study ranged from 15 to 76 years old, while the median value was 35.5 years old. Statistically significant correlation was observed between the SIRS occurrence rate and multiple rib fractures (p-value - 0.049), associated extra-thoracic injuries (p-value - 0.016) and higher MEWS score (p-value - 0.025). Statistically significant correlation was also observed between the rate of ARDS occurrence and all risk factors excluding age. Mortality was higher among patients with delayed presentation to hospital (p-value < 0.001), multiple rib fractures (p-value - 0.001), presence of bilateral thoracic injury (p-value < 0.001), associated extra-thoracic injuries (p-value - 0.004), as well as in patients who required ventilatory support (p-value < 0.001) or demonstrated low RTS (p-value - 0.006) and high MEWS (p-value - 0.005) on admission. This correlation was found to be statistically significant. Conclusion: High MEWS, associated extra-thoracic injuries and multiple rib fractures are good predictors of poor clinical outcome in terms of SIRS, ARDS and death. Aggressive treatment protocols should be established in order to achieve better outcomes in these patients. [ABSTRACT FROM AUTHOR]

Introduction: Emphysematous pyelonephritis (EPN), an acute necrotizing infection of the kidney and surrounding tissues, is associated with considerable mortality. We evaluated how existing critical care scoring systems could predict the need for intensive care unit (ICU) management for these patients. We also analyzed if CT-imaging further enhances these predictive systems. Patients and Methods: A retrospective analysis of 90 consecutive patients diagnosed clinico-radiologically with EPN from January 2011 to September 2020. Five scoring systems were evaluated for their predictive ability for the need for ICU management and mortality risk: National Early Warning Score (NEWS), Modified Early Warning Score (MEWS), 'quick' Sequential Organ Failure Assessment score (qSOFA), Systemic Inflammatory Response Syndrome score (SIRS), and Sequential Organ Failure Assessment score (SOFA). CT images were classified as per Huang & Tseng and evaluated as stand-alone or added to the different predictive models. Receiver operating characteristic (ROC) curves were plotted for each critical care score and CT-Class using logistic regression, to obtain the area under curve (AUC) value for comparison of ICU admission predictability. Patients were analyzed up till discharge. Results: Ninety patients were diagnosed with EPN. Twenty-six patients required ICU management and nine patients died. The best scoring system to predict the need of early ICU management is NEWS (AUC 0.884). CT Class had no independent predictive power, nor did it add significantly to improvement in most of the early warning scoring systems, but rather guided us to the need for radiological, endourological or surgical intervention. Conclusion: In patients with EPN, the NEWS scoring system predicts best the requirement of ICU care. It aids in triage of patients with EPN to appropriate early management and reduce mortality risk.

Introduction and objectives: Little is known about primary biliary cholangitis (PBC) in non-whites. The purpose of this study was to evaluate clinical features and outcomes of PBC in a highly admixed population. Material and methods: The Brazilian Cholestasis Study Group multicentre database was reviewed to assess demographics, clinical features and treatment outcomes of Brazilian patients with PBC. Results: 562 patients (95% females, mean age 51 § 11 years) with PBC were included. Concurrent autoimmune diseases and overlap with autoimmune hepatitis (AIH) occurred, respectively, in 18.9% and 14%. After a mean follow-up was 6.2 § 5.3 years, 32% had cirrhosis, 7% underwent liver transplantation and 3% died of liver-related causes. 96% were treated with ursodeoxycholic acid (UDCA) and 12% required add-on therapy with fibrates, either bezafibrate, fenofibrate or ciprofibrate. Response to UDCA and to UDCA/fibrates therapy varied from 39%-67% and 42-61%, respectively, according to different validated criteria. Advanced histological stages and non-adherence to treatment were associated with primary non-response to UDCA, while lower baseline alkaline phosphatase (ALP) and aspartate aminotransferase (AST) levels correlated with better responses to both UDCA and UDCA/fibrates. Conclusions: Clinical features of PBC in highly admixed Brazilians were similar to those reported in Caucasians and Asians, but with inferior rates of overlap syndrome with AIH. Response to UDCA was lower than expected and inversely associated with histological stage and baseline AST and ALP levels. Most of patients benefited from add-on fibrates, including ciprofibrate. A huge heterogeneity in response to UDCA therapy according to available international criteria was observed and reinforces the need of global standardization. [ABSTRACT FROM AUTHOR]

Conclusions: ΔPCO2 is a reliable index for early prediction of clinical outcome including organ dysfunction and mortality in patients with sepsis and septic shock. [ABSTRACT FROM AUTHOR]

The last 2 years yielded a proliferation of high-quality asthma research. These include new understandings of the incidence and natural history of asthma, findings on the effects of exposure to air pollution, allergens, and intake of acetaminophen, soy isoflavones, and polyunsaturated fatty acids, and exposure to microbial products. The past 2 years have benefited from great strides in determining potential mechanisms of asthma development and asthma exacerbations. These novel understandings led to identification and development of exciting new avenues for potential therapeutic intervention. Finally, there has been significant progress made in the development of tools to facilitate the diagnosis of asthma and measurement of airway physiology and in precision diagnostic approaches. Asthma guidelines were updated and new insights into the pharmacologic management of patients, including biologics, were reported. We review the most notable advances in the natural history of asthma, risk factors for the development of asthma, underlying mechanisms, diagnostic approaches, and treatments. Although greater knowledge of the mechanisms underlying responses and nonresponses to novel therapeutics and across asthma phenotypes would be beneficial, the progress over just the past 2 years has been immense and impactful.

Abstract Background Mechanical prosthetic heart valves are known for their durability; however, a malfunctioning prosthesis can deteriorate rapidly to become a life-threatening complication. Our aim was to calculate a numerical index to express the rate of clinical deterioration of patients presenting with a mechanical prosthetic heart valve thrombosis (PVT), called the index of deterioration (ID), and to evaluate its usefulness in predicting hospital outcomes. Results The median ID and range were (0.43, 0.03-3) NYHA class/day. A higher ID was significantly related to early development of PVT after native valve replacement, younger age, female gender, pregnancy, non-compliance to oral anticoagulation (OAC), low LVEF%, high mean pressure gradient across a mitral prosthesis, raised serum creatinine, and SGOT on admission (P < 0.05). Independent predictors were early presentation after native valve replacement, female gender, and non-compliance to OAC (P < 0.05). ID correlated positively with the need for urgent/emergency surgery, and the durations of cardiopulmonary bypass, postoperative mechanical ventilation, and positive inotropes. ID correlated negatively with the postoperative LVEF% (P < 0.05). Median ID of the 21 mortalities (0.75, 0.1-3) was > 2.1 times that of survivors (0.35: 0.03−2; P = 0.002), and the median ID of the 29 cases with postoperative complications (0.5, 0.1-1.5) was 2.5 times that of the 39 uneventful cases (0.2, 0.03-2; P = 0.011). The ID significantly predicted both mortality (odds ratio 3.87; 1.33-1.29; P = 0.013) and mortality and hospital complications (odds ratio 4.77; 1.49-15.2; P = 0.008). The respective discriminating abilities were AUC 0.734 (0.616-0.852; P = 0.002) and 0.724 (0.61-0.835; P < 0.001). EuroScore II correlated positively with ID (r = 0.571; P < 0.001) but showed better discriminative abilities. Conclusion The simple index of deterioration was useful in monitoring deterioration and predicting hospital progression and outcomes in patients presenting with PVT.

Background: Surgical treatment for esophageal cancer is a high-risk procedure. Prediction of postoperative adverse events could aid in the stratification of patients, thus improving outcomes as well as achieving optimal use of resources. The Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity (POSSUM) is a prediction model that utilizes both physiological and surgical parameters to assess risk. This study evaluates the effectiveness of POSSUM, Portsmouth-POSSUM (P-POSSUM), and esophagogastric-POSSUM (O-POSSUM) scoring systems in predicting postoperative morbidity and mortality in Indian patients operated for esophageal cancers. Patients and Methods: It is a retrospective study conducted in a tertiary care teaching hospital with data collected from esophagectomies performed from January 2015 to January 2019. The calibration and discriminative abilities of the scores to predict 30-day morbidity and mortality were analyzed using the Hosmer–Lemeshow test, observed to predicted ratios (observed/expected [O/E]), and the receiver operating characteristic curve tests. Results: A total of sixty patients were included. The 30-day mortality and morbidity were 6.67% (4/60) and 46.66% (28/60), respectively. POSSUM morbidity showed proper calibration and discrimination (O/E: 0.86) with a modest predictive ability (area under the curve [AUC]: 0.701). While analyzing mortality, though all scores displayed good calibration, O-POSSUM displayed superior predictive ability (O/E: 1.02). The POSSUM score overpredicted mortality by nearly twice (O/E: 0.52), whereas P-POSSUM underpredicted it (O/E: 1.71). All scores showed moderate discrimination with P-POSSUM outperforming other tests (AUC: 0.825). Conclusions: The POSSUM scoring system was useful in predicting morbidity risk following esophageal resection for cancer, with O-POSSUM more accurate for mortality prediction in this group of patients.

Introduction and objectives: Little is known about primary biliary cholangitis (PBC) in non-whites. The purpose of this study was to evaluate clinical features and outcomes of PBC in a highly admixed population. Material and methods: The Brazilian Cholestasis Study Group multicentre database was reviewed to assess demographics, clinical features and treatment outcomes of Brazilian patients with PBC. Results: 562 patients (95% females, mean age 51 ± 11 years) with PBC were included. Concurrent autoimmune diseases and overlap with autoimmune hepatitis (AIH) occurred, respectively, in 18.9% and 14%. After a mean follow-up was 6.2 ± 5.3 years, 32% had cirrhosis, 7% underwent liver transplantation and 3% died of liver-related causes. 96% were treated with ursodeoxycholic acid (UDCA) and 12% required add-on therapy with fibrates, either bezafibrate, fenofibrate or ciprofibrate. Response to UDCA and to UDCA/fibrates therapy varied from 39%-67% and 42-61%, respectively, according to different validated criteria. Advanced histological stages and non-adherence to treatment were associated with primary non-response to UDCA, while lower baseline alkaline phosphatase (ALP) and aspartate aminotransferase (AST) levels correlated with better responses to both UDCA and UDCA/fibrates.Conclusions: Clinical features of PBC in highly admixed Brazilians were similar to those reported in Caucasians and Asians, but with inferior rates of overlap syndrome with AIH. Response to UDCA was lower than expected and inversely associated with histological stage and baseline AST and ALP levels. Most of patients benefited from add-on fibrates, including ciprofibrate. A huge heterogeneity in response to UDCA therapy according to available international criteria was observed and reinforces the need of global standardization.

Introduction. Management of upper gastrointestinal bleeding (UGIB) is of great importance. In this way, we aimed to evaluate the performance of three well known scoring systems of AIMS65, Glasgow-Blatchford Score (GBS) and Full Rockall Score (FRS) in predicting adverse outcomes in patients with UGIB as well as their ability in identifying low risk patients for outpatient management. We also aimed to assess whether changing albumin cutoff in AIMS65 and addition of albumin to GBS add predictive value to these scores.

Background: Scoring systems play a crucial role in dermatology by providing objective measurements of disease severity, treatment efficacy, and outcome comparisons. In autoimmune blistering diseases (AIBDs), standardized scoring systems are essential for accurate evaluations; however, there is currently a lack of consensus on scoring methods., Objective: This literature review explores scoring systems in AIBDs by tracing their development, addressing challenges, and highlighting their role in defining endpoints, regulatory considerations, and clinical trials., Materials and Methods: Existing scoring systems for AIBDs, such as the Pemphigus Disease Area Index, Autoimmune Bullous Skin Disorder Intensity Score, Pemphigus Oral Lesions Intensity Score, Oral Disease Severity Score, and Pemphigus Vulgaris Activity Score, are examined for their validity, reliability, and responsiveness. The Bullous Pemphigoid Disease Area Index for bullous pemphigoid is also discussed. The concept of minimal clinically important differences is explored to determine clinically significant improvements in disease severity., Conclusion: This review provides a comprehensive understanding of the central role of scoring systems in dermatology and their implications for research and clinical practice in AIBDs., Competing Interests: There are no conflicts of interest., (Copyright: © 2024 Indian Dermatology Online Journal.)

Disseminated intravascular coagulation (DIC) is a critical, life-threatening disorder characterized by widespread activation of the coagulation cascade, leading to microthrombi formation, consumption of clotting factors and platelets, and a paradoxically increased risk of bleeding. Accurate and timely diagnosis is crucial for effective management and improved patient outcomes. This narrative review aims to evaluate the diagnostic accuracy and clinical utility of various scoring systems used to assess DIC. We examine prominent systems, including the International Society on Thrombosis and Haemostasis (ISTH) scoring system, the Japanese Association for Acute Medicine (JAAM) DIC criteria, and other regional or institutional criteria such as the Chinese DIC scoring system (CDSS). The review compares these systems based on their criteria, sensitivity, specificity, and accuracy across different patient populations and discusses their strengths and limitations. Additionally, we explore the impact of these scoring systems on patient management and therapeutic decisions, identify challenges and limitations, and highlight emerging trends and future directions in DIC diagnosis. By providing a comprehensive analysis, this review aims to enhance understanding of DIC scoring methods and inform clinical practice to improve patient care., Competing Interests: Conflicts of interest: In compliance with the ICMJE uniform disclosure form, all authors declare the following: Payment/services info: All authors have declared that no financial support was received from any organization for the submitted work.

Introduction Ileal perforation due to typhoid is common in tropical countries, and the ensuing secondary peritonitis is treated by resuscitation and surgery. The Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity (POSSUM) was developed to predict postoperative outcomes to overcome systemic obstacles in any healthcare setup and is considered fairly accurate. The Portsmouth-POSSUM (P-POSSUM) score was developed as a corrective scoring system for overestimations made by the POSSUM score vis-à-vis mortality. Our study aimed to examine the validity of these two scores in the postoperative prediction of surgical outcomes in patients with ileal perforation. Materials and methods An observational study involving 40 patients diagnosed with ileal perforations was undertaken over 18 months. The postoperative outcome for each patient was calculated as per the POSSUM and P-POSSUM parameters. Statistical analysis was done using SPSS (IBM Corp., Armonk, NY) and the results were tabulated. Results We found that age, gender, respiratory dysfunction, propensity for multiple surgeries, duration of surgery, co-morbidities, underlying malignancy, and systolic blood pressure played a significant role in determining postoperative outcomes. Haemoglobin, potassium, and urea levels were also found to be significantly associated with outcome. Cardiac signs, pulse, white blood cell count, Glasgow Coma Scale score, sodium, and electrocardiography, part of the physiological score parameters, were found to be insignificant in the prediction of postoperative outcomes. Among the intraoperative parameters, peritoneal soiling was found to be insignificant. Conclusion Some parameters inherent to POSSUM and P-POSSUM calculations appear to bear no statistical significance to the final score, highlighting that these need to be revisited and perhaps modified to further simplify the calculation. The POSSUM score is an excellent predictor of postoperative morbidity and mortality in ileal perforation patients but is of questionable reliability due to its tendency to overestimate them. P-POSSUM has a better predictive power of postoperative mortality by correcting POSSUM mortality overestimation., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Background: The global spread of Coronavirus Disease 2019 (COVID-19) underscores the urgent need for reliable methods to forecast the disease's severity and outcome, thereby facilitating timely interventions and reducing mortality rates. This study focuses on evaluating the clinical and laboratory profiles of patients with Omicron variant-induced COVID-19 pneumonia and assessing the efficacy of various scoring systems in prognosticating disease severity and mortality., Methods: In this retrospective analysis, we examined the clinical records of 409 individuals diagnosed with Omicron variant COVID-19 pneumonia. We documented the Pneumonia Severity Index, CURB-65, and MuLBSTA scores within the first 24 h and analyzed the sensitivity, specificity, positive predictive value, negative predictive value, and the area under the receiver operating characteristic curve for each scoring system to ascertain their predictive accuracy for disease severity and fatality risk., Results: The cohort's median age was 78 years, predominantly presenting with fever, cough, expectoration, fatigue, and gastrointestinal symptoms. Factors such as expectoration, fatigue, Glasgow Coma Scale score, lactate dehydrogenase levels, procalcitonin, creatinine levels, and co-occurrence of acute respiratory distress syndrome were identified as independent predictors of disease severity. Furthermore, age, oxygenation index, glucose levels, lactate dehydrogenase, and septic shock were independently associated with mortality. For severe disease prediction, the CURB-65, PSI, and MuLBSTA scores demonstrated sensitivities of 65.9%, 63.8%, and 79.7%, respectively, with specificities of 63.8%, 76.8%, and 60.9%, and AUROCs of 0.707, 0.750, and 0.728. To predict mortality risk, these scores at cutoffs of 1.5, 102.5, and 12.5 exhibited sensitivities of 83.3%, 96.3%, and 70.4%, specificities of 59.4%, 60.8%, and 65.4%, and AUROCs of 0.787, 0.850, and 0.736, respectively., Conclusion: The study cohort predominantly comprised elderly individuals with pre-existing health conditions. Elevated lactate dehydrogenase emerged as a significant marker for both disease severity and prognosis, sputum production, gastrointestinal symptoms, GCS score, creatinine, PCT, and ARDS as independent predictors of disease severity, and age, oxygenation index, glucose levels, and septic shock as independent mortality predictors in COVID-19 pneumonia patients. Among the scoring systems evaluated, Pneumonia Severity Index demonstrated superior predictive capability for both disease severity and mortality, suggesting its utility in forecasting the clinical outcomes of Omicron variant COVID-19 pneumonia., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Ni, Zhong, Xie and Ding.)

OBJECTIVE: Acute Cholecystitis (AC) accounts for a significant proportion of patients presenting to the Emergency Department with abdominal pain. We suggest grading the severity of AC with a simple system: TNM, an acronym borrowed by cancer staging where T indicated Temperature, N neutrophils and M Multiple organ failure. This retrospective-prospective observational study evaluates the predictive value of TNM score on mortality of patients with AC. PATIENTS AND METHODS: TNM was developed in a training cohort of 178 patients with AC who underwent cholecystectomy from February 2005 to December 2012 (retrospectives data). To verify the prognostic value of TNM score, we prospectively recruited 172 patients who were consecutively included and treated from January 2013 to July 2020 as the validation cohort. After defining the categories T, N and M, patients were grouped in stages. The variables analyzed were age, sex, American Society of Anesthesiologists (ASA) score, blood transfusion, temperature, neutrophils count, preoperative organ failure, immune-compromised status, stage. RESULTS: In the training cohort TNM staging was: none patient at stage 0; 6 patients at stage I; 71 patients at stage II; 71 patients at stage III; 30 patients at stage IV. Death occurred in 51 patients. ASA score, neutrophils count, preoperative organ failure, stage III-IV emerged as statistically significant different prognostic factors. ASA score (III-IV) and stage (III-IV) were significant independent predictors of post-operative mortality in multivariate analysis. Comparable results were observed in the validation cohort. CONCLUSIONS: TNM classification is very easy to use; it helps to define the mortality risk and it is useful to objectively compare patients with AC. [ABSTRACT FROM AUTHOR]

Background: In Taekwondo competitions, the rule is that points are scored when the impact of the kick reaches a predetermined threshold of strength. This study aimed to explore the adequacy of the protector and scoring system (PSS) designed to determine taekwondo body scoring based on a reference group model (RGM). Specifically, the kicking impact of the PSS was calculated using data from 188 matches fought during of 2018 Jakarta Asian Games. The RGM was designed based on empirical data by classifying the victory and defeat groups by gender and weight class, and the scoring method was set according to these criteria. Result: The result of this study are as follows. First, there was no difference in the average impact of kicks of taekwondo players by weight class. Second, result of setting up the kick scoring impact standards of taekwondo PSS by classifying the winning and non-winning groups, the kick scoring impact set by the WT was found to be high in all weight classes except 58 kg. Lastly, result of comparing the settings of impact to score according to weight classes, the kick scoring impact standard set by the WT was higher in heavyweight (men's: under 80 kg, + 80 kg, women's: under 67 kg, over 67 kg) than in the lightweight (men's: under 58 kg, under 63 kg, under 68 kg, women's: under 49 kg, under 53 kg, under 57 kg). Conclusion: The kick scoring impact set by the WT was found to be high in all weight classes except for the under 58 kg class defining kick scoring impact based on the standards of WT-certified PSS by classifying the matches into winning and non-winning groups. Finally, as a result of comparing the scoring impact settings according to weight class, the kick scoring impact standard set by the WT was higher for the heavier weight classes than for the lighter weight classes.

Introduction: Amongst critically ill trauma patients admitted to ICU and still alive and in ICU after 24 hours, it is unclear which trauma scoring system offers the best performance in predicting in-hospital mortality.Methods: The Australia and New Zealand Intensive Care Society Adult Patient Database and Victorian State Trauma Registry were linked using a unique patient identification number. Six scoring systems were evaluated: the Australian and New Zealand Risk of Death (ANZROD), Acute Physiology and Chronic Health Evaluation III (APACHE III) score and associated APACHE III Risk of Death (ROD), Trauma and Injury Severity Score (TRISS), Injury Severity Score (ISS), New Injury Severity Score (NISS) and the Revised Trauma Score (RTS). Patients who were admitted to ICU for longer than 24 hours were analysed. Performance of each scoring system was assessed primarily by examining the area under the receiver operating characteristic curve (AUROC) and in addition using standardised mortality ratios, Brier score and Hosmer-Lemeshow C statistics where appropriate. Subgroup assessments were made for patients aged 65 years and older, patients between 18 and 40 years of age, major trauma centre and head injury.Results: Overall, 5,237 major trauma patients who were still alive and in ICU after 24 hours were studied from 25 ICUs in Victoria, Australia between July 2008 and January 2018. Hospital mortality was 10.7%. ANZROD (AUROC 0.91; 95% CI 0.90-0.92), APACHE III ROD (AUROC 0.88; 95% CI 0.87-0.90), and APACHE III (AUROC 0.88; 95% CI 0.87-0.89) were the best performing tools for predicting hospital mortality. TRISS had acceptable overall performance (AUROC 0.78; 95% CI 0.76-0.80) while ISS (AUROC 0.61; 95% CI 0.59-0.64), NISS (AUROC 0.68; 95% CI 0.65-0.70) and RTS (AUROC 0.69; 95% CI 0.67-0.72) performed poorly. The performance of each scoring system was highest in younger adults and poorest in older adults.Conclusion: In ICU patients admitted with a trauma diagnosis and still alive and in ICU after 24 hours, ANZROD and APACHE III had a superior performance when compared with traditional trauma-specific scoring systems in predicting hospital mortality. This was observed both overall and in each of the subgroup analyses. The anatomical scoring systems all performed poorly in the ICU population of Victoria, Australia. [ABSTRACT FROM AUTHOR]

Objectives: In critical care it is crucial to appropriately assess the risk of mortality for each patient. This is especially relevant in pediatrics, with its need for accurate and repeatable scoring. Aim of this study was to evaluate an age-adapted version of the expanded Simplified Acute Physiology Score II; (p-SAPS II), a repeatable, newly-designed scoring system compared to established scores (Pediatric Sequential Organ Failure Assessment Score/pSOFA, Pediatric Logistic Organ Dysfunction Score-2/PELOD-2 and Pediatric Index of Mortality 3/PIM3).Design: This retrospective cohort pilot study included data collected from patients admitted to the Pediatric Intensive Care Unit (PICU) at the Medical University of Vienna between July 2017 through December 2018.Patients: 231 admissions were included, comprising neonates (gestational age of ≥ 37 weeks) and patients up to 18 years of age with a PICU stay longer than 48 h.Main Outcomes: Mortality risk prediction and discrimination between survivors and non-survivors were the main outcomes of this study. The primary statistical methods for evaluating the performance of each score were the area under the receiver operating characteristic curve (AUROC) and goodness-of-fit test.Results: Highest AUROC curve was calculated for p-SAPS II (AUC = 0.86; 95% CI: 0.77–0.96; p < 0.001). This was significantly higher than the AUROCs of PELOD-2/pSOFA but not of PIM3. However, in a logistic regression model including p-SAPS II and PIM3 as covariates, p-SAPS II had a significant effect on the accuracy of prediction (p = 0.003). Nevertheless, according to the goodness-of-fit test for p-SAPS II and PIM3, p-SAPS II overestimated the number of deaths, whereas PIM3 showed acceptable estimations. Repeatability testing showed increasing AUROC values for p-SAPS II throughout the clinical stay (0.96 at day 28) but still no significant difference to PIM 3. The prediction accuracy, although improved over the days and even exceeded PIM 3.Conclusions: The newly-created p-SAPS II performed better than the established PIM3 in terms of discriminating between survivors and non-survivors. Furthermore, p-SAPS II can be assessed repeatably throughout a patient's PICU stay what improves mortality prediction. However, there is still a need to optimize calibration of the score to accurately predict mortality sooner throughout the clinical stay.

Purpose: To evaluate the available tibial fracture non-union prediction scores and to analyse their strengths, weaknesses, and limitations. Methods: The first part consisted of a systematic method of locating the currently available clinico-radiological non-union prediction scores. The second part of the investigation consisted of comparing the validity of the non-union prediction scores in 15 patients with tibial shaft fractures randomly selected from a Level I trauma centre prospectively collected database who were treated with intramedullary nailing. Results: Four scoring systems identified: The Leeds-Genoa Non-Union Index (LEG-NUI), the Non-Union Determination Score (NURD), the FRACTING score, and the Tibial Fracture Healing Score (TFHS). Patients demographics: Non-union group: five male patients, mean age 36.4 years (18–50); Union group: ten patients (8 males) with mean age 39.8 years (20–66). The following score thresholds were used to calculate positive and negative predictive values for non-union: FRACTING score ≥ 7 at the immediate post-operative period, LEG-NUI score ≥ 5 within 12 weeks, NURD score ≥ 9 at the immediate post-operative period, and TFHS < 3 at 12 weeks. For the FRACTING, LEG-NUI and NURD scores, the positive predictive values for the development of non-union were 80, 100, 40% respectively, whereas the negative predictive values were 60, 90 and 90%. The TFHS could not be retrospectively calculated for robust accuracy. Conclusion: The LEG-NUI had the best combination of positive and negative predictive values for early identification of non-union. Based on this study, all currently available scores have inherent strengths and limitations. Several recommendations to improve future score designs are outlined herein to better tackle this devastating, and yet, unsolved problem. [ABSTRACT FROM AUTHOR]

The extent of peritoneal metastases (PM) largely determines the possibility of complete or optimal cytoreductive surgery in advanced ovarian cancer. An objective scoring system to quantify the extent of PM can help clinicians to decide whether or not to embark on CRS. Therefore several scoring systems have been developed by different research teams and this review summarizes their performance in predicting a complete or optimal cytoreduction in patients with advanced ovarian cancer. A systematic search in the MEDLINE database revealed 19 articles that described a total of five main scoring systems to predict the completeness of CRS in patients with FIGO stage III-IV ovarian cancer based on the surgical exploration of the abdominal cavity; PCI, PIV, Eisenkop, Espada, and Kasper. The Peritoneal Cancer Index (PCI) and the Predictive Index Value (PIV) were mentioned most frequently and showed AUCs of 0.69–0.92 and 0.66–0.98, respectively. Due to the use of different cut-offs sensitivities and specificities greatly varied. Therefore with the current data, no scoring system could be identified as best. An objective measure of the extent of disease can be of great clinical use for identifying ovarian cancer patients for which a complete (or optimal) CRS is achievable, however due to local differences in treatment strategies and surgical policy a widely adopted objective scoring system with a standard cut-off value is not feasible. Nevertheless, objective scoring systems can play an important role to guide treatment decisions. [ABSTRACT FROM AUTHOR]

Objective: This study compared the prognostic performances of the Brescia-COVID Respiratory Severity Scale (BCRSS) and the Quick COVID-19 Severity Index (qCSI) scores in hospitalized patients diagnosed with COVID-19. Methods: The data of all adult patients (over 18 y of age) who were admitted into a state hospital with confirmed COVID-19 between May 1, 2020, and October 31, 2020, were retrospectively examined. The area under the receiver operating characteristic (ROC) curve, known as the area under the curve (AUC), was used to assess the BCRSS prediction rule and the qCSI score to assess the discriminatory power in predicting in-hospital mortality and intensive care unit (ICU) admission. Results: There were 341 patients included in this study. The mean age of the patients was 58.2 ± 17.2, of which 165 were men and 176 were women, and 61.3% of patients had at least 1 comorbidity. The most common comorbidity was hypertension. The predictive power scores of BCRSS and qCSI were found as very good in terms of in-hospital mortality (AUC 0.804 and 0.847, respectively) and likewise in terms of ICU admission (AUC 0.842 and 0.851, respectively). Conclusions: Both BCRSS and qCSI scoring systems were found to be successful in predicting in-hospital mortality and ICU admission in our patient population. [ABSTRACT FROM AUTHOR]

Aim: Questionnaires designed to score the severity of faecal incontinence (FI) are widely used to provide an evaluation of symptoms across settings, studies and time. The Pelvic Floor Disorders Consortium have recommended the use of multiple questionnaires despite some overlap of questions. This study aimed to evaluate whether patient responses to these questionnaires are consistent. Method: A retrospective analysis was undertaken of patients with FI who attended a dedicated pelvic floor unit between January 2018 and December 2019 and completed the Fecal Incontinence Severity Index, Cleveland Clinic Florida Incontinence Score and St Mark's Incontinence Score simultaneously. For each questionnaire the frequency of incontinence episodes to solid stool, liquid stool and gas was divided into five categories to allow direct comparison. Answers were deemed equivalent if the allocated response was identical, slightly different if the response was in an adjacent category or very different if the response differed to a greater extent. Results: There were 193 patients who simultaneously completed all three FI questionnaires. There were statistically significant differences between the responses regarding frequency of solid stool, liquid stool and gas incontinence on all three questionnaires (p < 0.005). Across all domains, between 58.0% and 69.9% of responses were equivalent, 14.1%–34.0% of answers were slightly different and 8.0%–18.8% were very different. Conclusion: Even when completed at the same time, and by the same person, similar questions are answered differently a significant proportion of the time. The utility of using multiple questionnaires simultaneously in the clinical setting to assess FI symptoms should be questioned. [ABSTRACT FROM AUTHOR]

INTRODUCTION: Mortality rate is high in patients who are hospitalized in the Intensive Care Unit (ICU). Knowing the risk factors affecting mortality is important in determining the prognosis of the patient. This work; It was planned to compare the first and third day laboratory values with the scoring systems in determining the prognosis of the patients admitted to the YBU. METHODS: From November 2013 to April 2014, 86 patients from respiratory intensive care unit were included in the retrospective study. Sequential Organ Failure Assesment (SOFA), Acute Pysiology And Chronic Health Assessment (APACHE II), GCS (Glaskow Coma Score) and SAPS II (Simplified Acute Physilogy Score) scores were calculated during hospitalization. Laboratory parameters were studied at the first hours and at the end of 72 hours for all patients. The results were compared between the dead and the living. RESULTS: In the patients who died, SOFA, APACHE II and SAPS II scores were statistically significantly higher than patients who did not die. GCS was statistically lower (p

SAPS 3 included patients from 307 adult ICUs in 35 countries, but data collection took place over a mere 2 months, which resulted in a cohort of just 19,577 admissions for analysis: a mean of 539 patients per country, or 64 per ICU.

New outcomes included were ICU mortality, a patient's anticipated ICU length of stay, duration of mechanical ventilation, identifying low-risk monitor patients, along with daily predictions of mortality for individual patients ([14], [15]). Indeed, the transfer of extremely high-risk patients from ICUs in rural hospitals to ICUs in academic centers was accepted practice ([2]). [Extracted from the article]

Adnexal masses are rare in the young female population. The differential diagnosis includes ovarian masses, tubal/paratubal masses, masses related to the gastrointestinal tract (colon), infectious lesions, or pregnancy. Acute abdominal pain, and less commonly, precocious puberty or vaginal bleeding, are typical symptoms in these cases. The majority of adnexal masses in the paediatric and adolescent population are benign; however, a thorough preoperative assessment is essential to guide surgical intervention and optimise patient outcomes. The proper diagnosis of an adnexal mass, correct management (surgical or nonsurgical), and necessary referrals are of paramount importance. In the light of these cornerstones, this review describes the aetiologies, presenting symptoms, and appropriate diagnostic work-up for paediatric and adolescent patients affected by adnexal masses.
