- Abstract
OBJECTIVE: The outbreak of Severe Acute Respiratory Syndrome-CoronaVirus 2 (SARS-CoV-2) has rapidly spread throughout the world straining health care systems. Several biomarkers indicate the presence of hyper-inflammation and evaluate the severity of the disease. Our aim was to investigate the prognostic value of pancreatic stone protein plasma concentration in patients with SARS-CoV-2 pneumonia. PATIENTS AND METHODS: We prospectively studied 55 patients with acute SARS-CoV-2 pneumonia admitted to our tertiary hospital. Sepsis biomarkers, including pancreatic stone protein (PSP), were measured on admission. The role of these biomarkers in the prediction of in-hospital mortality (28 day) and length of hospital stay was investigated. RESULTS: Although Pancreatic stone protein did not have significant prognostic value for in-hospital mortality, there was a moderate accuracy for prolonged length of stay. The optimal cut-off value for prolonged hospital stay was 51 ng/dL (Sensitivity: 0.65, Specificity: 0.913). CONCLUSIONS: Pancreatic Stone Protein on admission could accurately identify patients requiring prolonged hospitalization. The results of this study can serve as a strong early basis for future validation studies of such an innovative approach. [ABSTRACT FROM AUTHOR]

- Abstract
Background: COVID-19 related syndromes are not yet well described and understood. Multisystem inflammatory syndrome of the adults (MIS-A) is a recently characterized syndrome affecting multiple organs of young adults, causing serious complications, even shock and death., Objectives: To determine the clinical characteristics, course, and complications of MIS-A in a systematic way and summarize currently used treatments., Methods: Literature search in March 2023 in PubMed and Scopus databases. Case reports and case-series that fulfilled the CDC criteria for MIS-A were eligible for inclusion., Results: A total of 71 patients from 60 reports were included. 66% of the patients were male and the mean age of the synthetic cohort was 32.9 years old. The majority (70.4%) of the enrolled cases had no significant medical history. MIS-A was diagnosed after a median of 4 weeks period. All but two patients presented with cardiac symptoms, while the most common secondary diagnostic criterion was abdominal pain, vomiting or diarrhea followed by shock or hypotension. Heart failure therapy and immunomodulation were used as therapeutic options. Although more than half of the cohort was admitted to the Intensive Care Unit (ICU) (n=39) only 4 deaths were reported., Conclusion: MIS-A can affect patients independently of age, sex, and co-morbidity status, resulting in serious complications, often including severe cardiac disease, shock, acute kidney injury and sometimes death. It can occur immediately after SARS-CoV-2 acute infection until two months later, usually manifesting four weeks after acute disease., Competing Interests: Conflicts of interest: The authors declare that there are not any conflicts of interest.

- Abstract
Background and Objectives : Multiple sclerosis is a chronic demyelinating disease of the central nervous system. Individuals with multiple sclerosis may require daily care and support from caregivers due to the disease's progressive and unpredictable nature. However, the role of caregiving is not without its challenges, and caregivers themselves often face significant repercussions in terms of their quality of life, mental health, and stress levels. Our study aims to investigate the level of stress caregivers experience in their everyday life and the way stress affects their quality of life. Materials and Methods : We conducted a multicenter, cross-sectional study from 11 November 2023 to 20 March 2024 in healthcare units in Western Greece. All 96 participants were adult caregivers of patients diagnosed with multiple sclerosis (MS). We assessed caregivers' quality of life and stress levels using the 36-item Short Form Health Survey and Kingston Caregiver Stress Scale, respectively. Non-parametric tests (Spearman's rho test, Kruskal-Wallis and Mann-Whitney tests) were used to identify possible correlations between the aforementioned scales and between stress levels and caregiver characteristics. Results : Caregivers reported high stress, with an average KCSS score of 36.82 ± 0.851. The mean SF-36 physical component summary score (PCS) was 59.59 ± 2.77, whereas the mental component summary score (MCS) was 45.69 ± 2.32. Stress levels in the KCSS were negatively correlated with both PCS and MCS of SF-36 and female gender, education level, monthly income, limits of mobility, and patient's level of dependence were associated with higher levels of stress. Conclusions : Stress was found to be negatively connected with caregivers' quality of life, affecting both physical and mental health. Female caregivers, caregivers with a primary education level and a low monthly income, and caregivers of patients with serious illnesses who rely primarily on daily help were the most affected.

- Abstract
Pancreatic stone protein (PSP) is an acute-phase reactant mainly produced in response to stress. Its diagnostic and prognostic accuracy for several types of infection has been studied in several clinical settings. The aim of the current review was to assess all studies examining a possible connection of pancreatic stone protein levels with the severity and possible complications of patients diagnosed with infection. We performed a systematic search in PubMed, Scopus, the Cochrane Library and Clinicaltrials.gov to identify original clinical studies assessing the role of pancreatic stone protein in the diagnosis and prognosis of infectious diseases. We identified 22 eligible studies. Ten of them provided diagnostic aspects, ten studies provided prognostic aspects, and another two studies provided both diagnostic and prognostic information. The majority of the studies were performed in an intensive care unit (ICU) setting, five studies were on patients who visited the emergency department (ED), and three studies were on burn-injury patients. According to the literature, pancreatic stone protein has been utilized in patients with different sites of infection, including pneumonia, soft tissue infections, intra-abdominal infections, urinary tract infections, and sepsis. In conclusion, PSP appears to be a useful point-of-care biomarker for the ED and ICU due to its ability to recognize bacterial infections and sepsis early. Further studies are required to examine PSP's kinetics and utility in specific populations and conditions.

- Abstract
Introduction: Patients being on immunosuppressive treatment of any reason, along with other risk factors such as smoking and obesity, are vulnerable to be infected from SARS-CoV2. Aim of this report is to describe a case of a female patient under Rituximab therapy who experienced episodes of lung infection due to Severe Acute Coronavirus 2 (SARS-CoV-2 ) invasion although fully vaccinated., Case Report: A 50-year-old woman, with a past medical history of lupus nephritis on rituximab was diagnosed with lung infection due to SARS-CoV-2. Eight months later, following her last infusion of Rituximab (RTX), she developed moderate Coronavirus Disease 2019 (COVID-19). After a partial recovery, she exhibited exacerbation of respiratory symptoms leading to readmission and invasive oxygenation. She was eventually discharged home after 31 days. Her monthly neurological evaluation did not reveal evidence of disease activity. She later received intravenous immunoglobulin and a decision was made to restart rituximab., Conclusions: This case raises the possibility of persistent virus shedding and reactivation of severe acute respiratory syndrome coronavirus in a patient with SLE and Rituximab therapy. We emphasize a precise consideration of management of patients with autoimmune disorders during the COVID-19 pandemic.

- Abstract
Objectives: Biomarker-based clinical practice is currently gaining ground and increasingly affects decision making. A variety of biomarkers have been studied through the years and some of them have already an established role in modern medicine, such as procalcitonin (PCT) which has been proposed to reduce antibiotic exposure. We purposed to systematically review all biomarkers examined for guiding the clinical practice in patients with pneumonia., Methods: A systematic review on PubMed was performed on April 2023 by two independent researchers using the PRISMA guidelines. Randomized trials which enrolled patients with pneumonia and compared biomarker-guided strategies to standard of care were included., Results: 1242 studies were recorded, from whom 16 were eligible for this study. 14 studies investigated PCT as a biomarker. From these, 8 studies reported on community acquired pneumonia (CAP), 2 on ventilator associated pneumonia (VAP), 1 on aspiration pneumonia, 1 on hospital acquired pneumonia (HAP) and 2 on exacerbation of chronic obstructive pulmonary disease (ECOPD). There was 1 study, referred to VAP, that investigated interleukin-1β (IL-1β) and interleukin-8 (IL-8) and 1 study that reported the role of C-reactive protein (CRP) in ECOPD. In a total of 4751 patients in 15 studies, the biomarker-based approach did not lead to increased mortality [OR: 0.998 (95%CI: 0.74-1.34, p value: 0.991). I2:19%]. Among different types of pneumonia and time-points of assessment, biomarker-guided practice appeared to improve antibiotic-related outcomes, such as rate of antibiotic prescription, duration of antibiotic therapy and rate of antibiotic exposure, while 5 studies reported a possible decrease in antibiotic-related adverse effects. Biomarker-guided practice did not seem to lead in an increase in other adverse outcomes such as need for hospitalization and duration of hospitalization. However, the included studies have high risk of bias mainly due to improper blinding of participants/personnel and outcome assessors., Conclusion: Biomarker-guided clinical practice improves provided healthcare, in terms of reduced antibiotic consumption with no inferiority to mortality, relapses and exacerbations in patients with different types of pneumonia. Thus, such approaches should be further evaluated to achieve personalized medicine., (© 2023 Dimitrios Dimitropoulos et al., published by Sciendo.)

- Abstract
Aims and Objectives: the present study aimed to assess the knowledge and attitudes of medical and nursing students at the University of Patras, western Greece, regarding sexually transmitted infections (STIs), sexual behavior and STI prevention measures, as well as the level of future healthcare professionals' education., Method: A descriptive, cross-sectional study was conducted. A total of 231 medical and nursing students ( n = 106 medical, and n = 125 nursing) completed and returned the pre-tested study questionnaire., Results: Most participants (77.5%) were females and46.1% were in the age group of 18-21 years. Syphilis, HIV/AIDS, and Hepatitis B were regarded as STIs by 65.8% of them. Medical students could predominantly list the widely known STIs compared to nursing students ( p = 0.004). Regarding HIV/AIDS, 72.7% of the respondents reported that it is transmitted sexually and through blood transfusion. However, medical students were better informed than nursing students ( p = 0.001). Medical students as well as students in the final year of their studies were found to be better informed about the vaccines available to prevent STIs. Regarding the question about what constitutes a risky sexual behavior, 71.4% answered sexual intercourse without the use of condom and 18.6% indicated having sex with an unknown partner. Most participants (69.7%) were satisfied with the education provided by their institution and no statistically significant difference was observed between medical and nursing students. Almost all students (97.8%) agreed that the course/subject of sex education must be included in school programs., Conclusions: A comprehensive analysis of knowledge and attitudes of Greek medical and nursing students regarding STIs, prevention measures and education level was conducted. The results of the present study could assist in the development of targeted training courses that can improve healthcare professionals' knowledge and ability to manage STIs.

- Abstract
Antibiotic resistance (ABR) and antimicrobial stewardship arethe two sides of the same coin that constitute a public health hydra. This study aimed to assessthe knowledge and attitude of healthcare workers (HCWs), on antibiotic use and antimicrobial resistance in Western Greece. A total of 200 healthcare workers (doctors, nurses, and others) from the two largest tertiary hospitals in Western Greece were included in our survey. HCWs seem not to decide based on patient opinion in order to prescribe antibiotics. Approximately 97% of them are aware of their main adverse effects. Remarkably, 25% of respondents prescribe antibiotics due to diagnostic uncertainty, and 32.5% of them prescribe antibiotics based on their experience. HCWs statedthat they do not report adverse effects often. Inappropriate antibiotic prescriptions were mentioned as the main reason for bacterial resistance to antimicrobials. Monitoring the patient's treatment progress, using electronic prescriptions, and adhering to international guidelines were suggested as solutions to the problem. Post Hoc analysis showed that nursing staff apply to the national guidelines (p: 0.011) and use electronic prescriptions (p: 0.003) less often compared to consultants, doctor directors, and trainees. The findings of our survey may be useful for the development of future national education programs and interventions thatmay improve healthcare workers' knowledge and ability to manage antibiotics.

- Abstract
Background: The Pancreatic Stone Protein (PSP) is an acute-phase protein that is mainly secreted by pancreatic cells in response to stress. The current literature supports its use as a predictor of sepsis. Its prognostic role has recently been evaluated in a point-of-care setting, mostly in high-risk patients. We conducted a prospective observational cohort study to evaluate its utility in the prognosis of patients admitted to the hospital with a diagnosis of intra-abdominal infection., Methods: Adult patients consecutively admitted to the Internal Medicine Department of the University Hospital of Patras, Greece, with a diagnosis of intra-abdominal infection were enrolled. PSP levels were measured within 24 h of admission in whole blood., Results: a total of 40 patients were included after being diagnosed with IAI. PSP was used as an independent predictive factor for sepsis after adjusting for age with OR = 7.888 (95% CI: 1.247-49.890). PSP also predicted readmission and the need for treatment escalation ( p : <0.01) and was an excellent prognostic factor regarding these outcomes (AUC = 0.899, 95% CI: 0.794-1.0, and AUC = 0.862, 95% CI: 0.748-0.976, respectively). PSP also proved superior to CRP, ferritin, and fibrinogen in sepsis diagnosis, treatment escalation, and readmission prediction with an AUC of 0.862, 0.698, and 0.899, respectively., Conclusions: PSP can predict unfavorable outcomes, such as sepsis development, readmission, and the need for treatment escalation among patients with intra-abdominal infections.

- Abstract
Atrial fibrillation (AF) is the most common arrhythmia with a high burden of morbidity including impaired quality of life and increased risk of thromboembolism. Early detection and management of AF could prevent thromboembolic events. Artificial intelligence (AI)--based methods in healthcare are developing quickly and can be proved as valuable for the detection of atrial fibrillation. In this metanalysis, we aim to review the diagnostic accuracy of AI-based methods for the diagnosis of atrial fibrillation. A predetermined search strategy was applied on four databases, the PubMed on 31 August 2022, the Google Scholar and Cochrane Library on 3 September 2022, and the Embase on 15 October 2022. The identified studies were screened by two independent investigators. Studies assessing the diagnostic accuracy of AI-based devices for the detection of AF in adults against a gold standard were selected. Qualitative and quantitative synthesis to calculate the pooled sensitivity and specificity was performed, and the QUADAS-2 tool was used for the risk of bias and applicability assessment. We screened 14,770 studies, from which 31 were eligible and included. All were diagnostic accuracy studies with case-control or cohort design. The main technologies used were: (a) photoplethysmography (PPG) with pooled sensitivity 95.1% and specificity 96.2%, and (b) single-lead ECG with pooled sensitivity 92.3% and specificity 96.2%. In the PPG group, 0% to 43.2% of the tracings could not be classified using the AI algorithm as AF or not, and in the single-lead ECG group, this figure fluctuated between 0% and 38%. Our analysis showed that AI-based methods for the diagnosis of atrial fibrillation have high sensitivity and specificity for the detection of AF. Further studies should examine whether utilization of these methods could improve clinical outcomes.

- Abstract
Background: Free oxygen radicals have been implicated in the pathogenesis of bronchopulmonary dysplasia (BPD) in preterm infants. Superoxide dismutase (SOD) is a naturally occurring enzyme which provides a defense against such oxidant injury. Providing supplementary SOD has been tested in clinical trials to prevent BPD in preterm infants., Objectives: To determine the efficacy and safety of SOD in the prevention and treatment of BPD on mortality and other complications of prematurity in infants at risk for, or having BPD., Search Methods: We searched CENTRAL, PubMed, Embase, and three trials registers on 22 September 2022 together with reference checking, citation searching and contact with study authors to identify additional studies., Selection Criteria: Randomized, quasi-randomized and cluster-randomized controlled trials (RCTs) where the participants were preterm infants who had developed, or were at risk of developing BPD, and who were randomly allocated to receive either SOD (in any form, by any route, any dose, anytime) or placebo, or no treatment., Data Collection and Analysis: We used standard Cochrane methods. Our primary outcomes were BPD defined as an oxygen requirement at 28 days, BPD defined as oxygen at 36 weeks' postmenstrual age, neonatal mortality, mortality prior to discharge, and BPD or death at 36 weeks' postmenstrual age. We reported risk ratio (RR) and risk difference (RD) with 95% confidence intervals (CIs) for the dichotomous outcomes. We used GRADE to assess certainty of evidence for each outcome., Main Results: We included three RCTs (380 infants) on SOD administration in preterm infants at risk for BPD, and no studies in preterm infants with evolving BPD / early respiratory insufficiency. The evidence is very uncertain about the effect of SOD on BPD defined as an oxygen requirement at 28 days (RR 1.09, 95% CI 0.94 to 1.26; RD 0.06, 95% CI -0.05 to 0.16, 1 study, 302 infants; I
2 for RR and RD not applicable), BPD defined as oxygen at 36 weeks' postmenstrual age (RR 0.96, 95% CI 0.72 to 1.29; RD -0.01, 95% CI -0.11 to 0.09, 2 studies, 335 infants; I2 for RR and RD = 0%), neonatal mortality (RR 0.98, 95% CI 0.57 to 1.68; RD -0.00, 95% CI -0.08 to 0.07, 2 studies, 335 infants; I2 for RR and RD = 0%), and mortality prior to discharge (RR 1.20, 95% CI 0.53 to 2.71; RD 0.04, 95% CI -0.14 to 0.23, 2 studies, 78 infants; I2 for RR and RD = 0%). No studies reported BPD or death at 36 weeks' postmenstrual age. The evidence is very uncertain about the effect of SOD on retinopathy of prematurity any stage (RR 0.95, 95% CI 0.78 to 1.15; RD -0.03, 95% CI -0.15 to 0.08, 2 studies, 335 infants; I2 for RR = 0%, I2 for RD = 8%), and severe retinopathy of prematurity (ROP) (RR 0.97, 95% CI 0.57 to 1.65; RD -0.01, 95% CI -0.10 to 0.09, 1 study, 244 infants; I2 for RR and RD not applicable). No studies reported moderate to severe neurodevelopmental outcome at 18 to 24 months. Certainty of evidence was very low for all outcomes. We identified no ongoing trials., Authors' Conclusions: The evidence is very uncertain about the effect of SOD on BPD defined as an oxygen requirement at 28 days, BPD defined as oxygen at 36 weeks' postmenstrual age, neonatal mortality and mortality prior to discharge compared to placebo. No studies reported BPD or death at 36 weeks' postmenstrual age and need for supplemental oxygen. The evidence is very uncertain about the effect of SOD on retinopathy of prematurity any stage and severe retinopathy of prematurity. No studies reported moderate to severe neurodevelopmental outcome at 18 to 24 months. The effects of SOD in preterm infants has not been reported in any trial in the last few decades, considering that the most recent trial on SOD in preterm infants was conducted in 1997/1998, and no new studies are ongoing. In the light of the limited available evidence, new data from preclinical and observational studies are needed to justify the conduction of new RCTs. Observational studies might report how SOD is administered, including indication, dose and association with relevant outcomes such as mortality, BPD and long-term neurodevelopment., (Copyright © 2023 The Cochrane Collaboration.

- Abstract
Objectives: Sepsis is a life-threatening condition characterized by organ dysfunction. It occurs due to the host's dysregulated response to an infection. Clinicians use inflammatory biomarkers to evaluate patients at risk of sepsis in various settings., Methods: We included studies focusing on the diagnostic accuracy of presepsin in patients under suspicion of sepsis. The bivariate model of Reitsma was used for the quantitative synthesis, and summary estimates were calculated. The Zhou-Dendukuri approach was followed to assess heterogeneity. Subgroup analyses were performed based on settings and diagnostic criteria., Results: The summary sensitivity for diagnosing sepsis was 0.805 (95 % CI: 0.759-0.844), while the false positive rate (FPR) was 0.174 (95 % CI: 0.124-0.239). The area under the curve (AUC) for the summary receiver operating characteristic (SROC) curve was 0.875, with a slightly lower partial AUC of 0.833. The analysis using the Zhou-Dendukuri approach revealed low heterogeneity (I2 = 15.9 %). Subgroup analyses showed no significant differences in SROC curves and summary estimates between the ED and ICU settings, although the ED subgroup exhibited higher heterogeneity (I2 = 52.7 % vs. 20.2 %). The comparison between the diagnostic criteria, Sepsis 1 and Sepsis 3, demonstrated similar summary estimates and SROC curves. The examination of the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool revealed a high risk of bias regarding the participants and their applicability. Also, there was an increased risk of bias in all the studies concerning the index test., Conclusion: Based on our research, presepsin is a promising biomarker for triage and early diagnosis of sepsis., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier B.V.

- Abstract
Background: Germinal matrix hemorrhage and intraventricular hemorrhage (GMH-IVH) may contribute to neonatal morbidity and mortality and result in long-term neurodevelopmental sequelae. Appropriate pain and sedation management in ventilated preterm infants may decrease the risk of GMH-IVH; however, it might be associated with harms., Objectives: To summarize the evidence from systematic reviews regarding the effects and safety of pharmacological interventions related to pain and sedation management in order to prevent GMH-IVH in ventilated preterm infants., Methods: We searched the Cochrane Library August 2022 for reviews on pharmacological interventions for pain and sedation management to prevent GMH-IVH in ventilated preterm infants (< 37 weeks' gestation). We included Cochrane Reviews assessing the following interventions administered within the first week of life: benzodiazepines, paracetamol, opioids, ibuprofen, anesthetics, barbiturates, and antiadrenergics. Primary outcomes were any GMH-IVH (aGMH-IVH), severe IVH (sIVH), all-cause neonatal death (ACND), and major neurodevelopmental disability (MND). We assessed the methodological quality of included reviews using the AMSTAR-2 tool. We used GRADE to assess the certainty of evidence., Main Results: We included seven Cochrane Reviews and one Cochrane Review protocol. The reviews on clonidine and paracetamol did not include randomized controlled trials (RCTs) matching our inclusion criteria. We included 40 RCTs (3791 infants) from reviews on paracetamol for patent ductus arteriosus (3), midazolam (3), phenobarbital (9), opioids (20), and ibuprofen (5). The quality of the included reviews was high. The certainty of the evidence was moderate to very low, because of serious imprecision and study limitations. Germinal matrix hemorrhage-intraventricular hemorrhage (any grade) Compared to placebo or no intervention, the evidence is very uncertain about the effects of paracetamol on aGMH-IVH (risk ratio (RR) 0.89, 95% confidence interval (CI) 0.38 to 2.07; 2 RCTs, 82 infants; very low-certainty evidence); midazolam may result in little to no difference in the incidence of aGMH-IVH (RR 1.68, 95% CI 0.87 to 3.24; 3 RCTs, 122 infants; low-certainty evidence); the evidence is very uncertain about the effect of phenobarbital on aGMH-IVH (RR 0.99, 95% CI 0.83 to 1.19; 9 RCTs, 732 infants; very low-certainty evidence); opioids may result in little to no difference in aGMH-IVH (RR 0.85, 95% CI 0.65 to 1.12; 7 RCTs, 469 infants; low-certainty evidence); ibuprofen likely results in little to no difference in aGMH-IVH (RR 0.99, 95% CI 0.81 to 1.21; 4 RCTs, 759 infants; moderate-certainty evidence). Compared to ibuprofen, the evidence is very uncertain about the effects of paracetamol on aGMH-IVH (RR 1.17, 95% CI 0.31 to 4.34; 1 RCT, 30 infants; very low-certainty evidence). Compared to midazolam, morphine may result in a reduction in aGMH-IVH (RR 0.28, 95% CI 0.09 to 0.87; 1 RCT, 46 infants; low-certainty evidence). Compared to diamorphine, the evidence is very uncertain about the effect of morphine on aGMH-IVH (RR 0.65, 95% CI 0.40 to 1.07; 1 RCT, 88 infants; very low-certainty evidence). Severe intraventricular hemorrhage (grade 3 to 4) Compared to placebo or no intervention, the evidence is very uncertain about the effect of paracetamol on sIVH (RR 1.80, 95% CI 0.43 to 7.49; 2 RCTs, 82 infants; very low-certainty evidence) and of phenobarbital (grade 3 to 4) (RR 0.91, 95% CI 0.66 to 1.25; 9 RCTs, 732 infants; very low-certainty evidence); opioids may result in little to no difference in sIVH (grade 3 to 4) (RR 0.98, 95% CI 0.71 to 1.34; 6 RCTs, 1299 infants; low-certainty evidence); ibuprofen may result in little to no difference in sIVH (grade 3 to 4) (RR 0.82, 95% CI 0.54 to 1.26; 4 RCTs, 747 infants; low-certainty evidence). No studies on midazolam reported this outcome. Compared to ibuprofen, the evidence is very uncertain about the effects of paracetamol on sIVH (RR 2.65, 95% CI 0.12 to 60.21; 1 RCT, 30 infants; very low-certainty evidence). Compared to midazolam, the evidence is very uncertain about the effect of morphine on sIVH (grade 3 to 4) (RR 0.08, 95% CI 0.00 to 1.43; 1 RCT, 46 infants; very low-certainty evidence). Compared to fentanyl, the evidence is very uncertain about the effect of morphine on sIVH (grade 3 to 4) (RR 0.59, 95% CI 0.18 to 1.95; 1 RCT, 163 infants; very low-certainty evidence). All-cause neonatal death Compared to placebo or no intervention, the evidence is very uncertain about the effect of phenobarbital on ACND (RR 0.94, 95% CI 0.51 to 1.72; 3 RCTs, 203 infants; very low-certainty evidence); opioids likely result in little to no difference in ACND (RR 1.12, 95% CI 0.80 to 1.55; 5 RCTs, 1189 infants; moderate-certainty evidence); the evidence is very uncertain about the effect of ibuprofen on ACND (RR 1.00, 95% CI 0.38 to 2.64; 2 RCTs, 112 infants; very low-certainty evidence). Compared to midazolam, the evidence is very uncertain about the effect of morphine on ACND (RR 0.31, 95% CI 0.01 to 7.16; 1 RCT, 46 infants; very low-certainty evidence). Compared to diamorphine, the evidence is very uncertain about the effect of morphine on ACND (RR 1.17, 95% CI 0.43 to 3.19; 1 RCT, 88 infants; very low-certainty evidence). Major neurodevelopmental disability Compared to placebo, the evidence is very uncertain about the effect of opioids on MND at 18 to 24 months (RR 2.00, 95% CI 0.39 to 10.29; 1 RCT, 78 infants; very low-certainty evidence) and at five to six years (RR 1.6, 95% CI 0.56 to 4.56; 1 RCT, 95 infants; very low-certainty evidence). No studies on other drugs reported this outcome., Authors' Conclusions: None of the reported studies had an impact on aGMH-IVH, sIVH, ACND, or MND. The certainty of the evidence ranged from moderate to very low. Large RCTs of rigorous methodology are needed to achieve an optimal information size to assess the effects of pharmacological interventions for pain and sedation management for the prevention of GMH-IVH and mortality in preterm infants. Studies might compare interventions against either placebo or other drugs. Reporting of the outcome data should include the assessment of GMH-IVH and long-term neurodevelopment., (Copyright © 2023 The Cochrane Collaboration. Published by John Wiley & Sons, Ltd.)

- Abstract
Introduction: Chest X-rays are commonly used to assess the severity in patients that present in the emergency department with suspected COVID-19 pneumonia, but in clinical practice quantitative scales are rarely employed., Aims: To evaluate the reliability and validity of two semi-quantitative radiological scales in patients hospitalized for COVID-19 pneumonia (BRIXIA score and RALE score)., Methods: Patients hospitalized between October 2021 and March 2022 with confirmed COVID-19 pneumonia diagnosis were eligible for inclusion. All included patients had a chest X-ray taken in the ED before admission. Three raters that participated in the treatment and management of patients with COVID-19 during the pandemic independently assessed chest X-rays., Results: Intraclass coefficients for BRIXΙA and RALES was 0.781 (0.729-0.826) and 0.825 (0.781-0.862) respectively, showing good to excellent reliability overall. Pairwise analysis was performed using quadratic weighted kappa showing significant variability in the inter-rater agreement. The prognostic accuracy of the two scores for in-hospital mortality for all raters was between 0.753 and 0.763 for BRIXIA and 0.737 and 0.790 for RALES, demonstrating good to excellent prognostic value. Both radiological scores were significantly associated with inhospital mortality after adjustment for 4C Mortality score. We found a consistent upwards trend with significant differences between severity groups in both radiological scores., Conclusion: Our findings suggest that BRIXIA and RALES are reliable and can be used to assess the prognosis of patients with COVID-19 requiring hospitalization. However, the inherent subjectivity of radiological scores might make it difficult to set a cut-off value suitable for all assessors., (© 2023 Themistoklis Paraskevas et al., published by Sciendo.)

- Abstract
Introduction: The sepsis syndrome is potentially affecting several organs and systems irrespectively of the primary source of the infection. Alterations of the brain function in sepsis patients may result either from a primary central nervous system (CNS) infection or could be part of the sepsis-associated encephalopathy (SAE), a common complication of sepsis, characterized by a diffuse dysfunction of the brain due to an infection elsewhere in the body without overt CNS infection. Aim of the study was to evaluate the usefulness of electroencephalography and the biomarker neutrophil gelatinase-associated lipocalin (NGAL) when measured in the cerebrospinal fluid (CSF) in the management of these patients., Methods: Patients presenting at the emergency department with altered mental status and signs of infection were included in this study. Among initial assessment and treatment of the patients based on the international guidelines for treating sepsis, NGAL was measured in the cerebrospinal fluid (CSF) using ELISA technique. Electroencephalography was performed when possible within 24 hours after admission and EEG abnormalities were recorded., Results: 32 of 64 patients included in this study were diagnosed with central nervous system (CNS) infection. CSF NGAL was significantly higher in patients with CNS infection compared to patients without CNS infection (18.1 [5.1-71.1] vs 3.6 [1.2-11.6]; p<0.001). There was a trend for higher CSF NGAL in patients with EEG abnormalities, which did not reach statistical significance (p=0.106). CSF NGAL levels were similar between survivors and non-survivors (medians: 7.04 vs 11.79)., Conclusion: In patients presenting at the emergency department with altered mental status and signs of infection, CSF NGAL was significantly higher in patients with CSF infection. Its role in this acute setting should be evaluated further. CSF NGAL could be suggestive of EEG abnormalities., (© 2023 Christina Platanaki et al., published by Sciendo.)

- Abstract
Since severe acute respiratory syndrome coronavirus 2 led to a world pandemic, extensive research has been conducted to identify its characteristics and form an appropriate management plan. One recognized complication of COVID-19 is coagulation defects that can lead to thromboembolic events. We have reviewed the literature to summarize and present the latest research about the pathophysiology, clinical manifestations, anticoagulation use and appropriate dose in COVID-19 patients, as well as the effect of anticoagulation in outpatient and post-hospital settings. The pathophysiology of coagulation abnormalities in COVID-19 is not fully understood yet, but multiple mechanisms appear to be involved, such as a direct viral attack, hyperinflammation, increased immune response, blood stasis, and endothelial injury. Clinical manifestations are mainly venous thromboembolism (deep vein thrombosis and pulmonary embolism), arterial thromboembolism, ischemic stroke, central venous sinus thrombosis, and central retinal vein occlusion. Anticoagulation is widely used in hospitalized patients with COVID-19, unless it is contraindicated. Heparinoid is the main anticoagulant used. However, the appropriate dosage is still debated as research is trying to find a balance between benefits and risks. In outpatients, it appears that anticoagulation has no benefit in contrast to post-hospitalization use, where benefit could be observed in severely affected patients. We concluded that thromboprophylaxis should be used in treating hospitalized COVID-19 patients, but the dosage is still a matter of debate. More research needs to be done on outpatient and post-hospitalized patients to derive accurate conclusions.

- Abstract
Background: N-acetylcysteine (NAC) is a mucolytic agents with anti-inflammatory properties that has been suggested as an adjunctive therapy in patients with COVID-19 pneumonia., Objectives: We conducted a systematic review and meta-analysis to evaluate available evidence on the possible beneficial effects of NAC on SARS-CoV-2 infection., Methods: In September 2022, we conducted a comprehensive search on Pubmed/Medline and Embase on randomized controlled trials (RCTs) and observational studies on NAC in patients with COVID-19 pneumonia. Study selection, data extraction and risk of bias assessment was performed by two independent authors. RCTs and observational studies were analyzed separately., Results: We included 3 RCTs and 5 non-randomized studies on the efficacy of NAC in patients with COVID-19, enrolling 315 and 20826 patients respectively. Regarding in-hospital mortality, the summary effect of all RCTs was OR: 0.85 (95% CI: 0.43 to 1.67, I
2 =0%) and for non-randomized studies OR: 1.02 (95% CI: 0.47 to 2.23, I2 =91%). Need for ICU admission was only reported by 1 RCT (OR: 0.86, 95% CI:0.44-1.69, p=0.66), while all included RCTs reported need for invasive ventilation (OR:0.91, 95% CI:0.54 to 1.53, I2 =0). Risk of bias was low for all included RCTs, but certainty of evidence was very low for all outcomes due to serious imprecision and indirectness., Conclusion: The certainty of evidence in the included studies was very low, thus recommendations for clinical practice cannot be yet made. For all hard clinical outcomes point estimates in RCTs are close to the line of no effect, while observational studies have a high degree of heterogeneity with some of them suggesting favorable results in patients receiving NAC. More research is warranted to insure that NAC is both effective and safe in patients with COVID-19 pneumonia., (© 2023 Themistoklis Paraskevas et al., published by Sciendo.)- Published

- Abstract
Background: Along with important factors that worsen the clinical outcome of COVID-19, it has been described that bacterial infections among patients positive for a SARS-CoV-2 infection can play a dramatic role in the disease process. Co-infections or community-acquired infections are recognized within the first 48 h after the admission of patients. Superinfections occur at least 48 h after admission and are considered to contribute to a worse prognosis. Microbiologic parameters differentiate infections that happen after the fifth day of hospitalization from those appearing earlier. Specifically, after the fifth day, the detection of resistant bacteria increases and difficult microorganisms emerge., Objectives: The aim of the study was to evaluate the impact of bacterial infections in patients with COVID-19 on the length of the hospital stay and mortality., Methods: A total of 177 patients hospitalized due to COVID-19 pneumonia were consecutively sampled during the third and fourth wave of the pandemic at a University Hospital in Greece. A confirmed bacterial infection was defined as positive blood, urinary, bronchoalveolar lavage (BAL) or any other infected body fluid. Patients with confirmed infections were further divided into subgroups according to the time from admission to the positive culture result., Results: When comparing the groups of patients, those with a confirmed infection had increased odds of death (odds ratio: 3.634; CI 95%: 1.795-7.358; p < 0.001) and a longer length of hospital stay (median 13 vs. 7 days). A late onset of infection was the most common finding in our cohort and was an independent risk factor for in-hospital death. Mortality and the length of hospital stay significantly differed between the subgroups., Conclusion: In this case series, microbial infections were an independent risk factor for a worse outcome among patients with COVID-19. Further, a correlation between the onset of infection and a negative outcome in terms of non-infected, community-acquired, early hospital-acquired and late hospital-acquired infections was identified. Late hospital-acquired infections increased the mortality of COVID-19 patients whilst superinfections were responsible for an extended length of hospital stay.

- Abstract
Background: Burnout is increasingly being recognized as a major concern, affecting the physical and mental well-being of Healthcare workers (HCWs)., Objective: The aim of the study was to investigate the incidence of occupational exhaustion in healthcare workers (doctors, nurses, paramedics, assistants, administrative staff) and possible contributing factors during the COVID-19 pandemic., Methods: This study was conducted from March to September 2022 in seven (7) hospitals in Western Greece. It was carried out using an anonymous questionnaire. The questionnaire was designed based on results of previously published studies and consisted of 22 multiple-choice questions., Results: There were 259 (60.2%) female and 178 (39.8%) male participants enrolled in the study. The majority of the respondents were nurses (n=207, 48.1%), followed by doctors (n+ 178, 41.4%). There was a marked increase in emotional exhaustion, depersonalization, personal fulfillment and pandemic-related total burnout in participants older than 61 years old (40,05±2,2, 27,16±1,0, 21,11±4,1, 88,32±4,3, respectively). Widow/ers healthcare workers were mostly affected from pandemic related burnout compared to married, unmarried, and divorced healthcare workers. Respondents without postgraduate education demonstrated significantly greater prevalence of emotional exhaustion, depersonalization and pandemic-related total burnout in comparison to those with doctoral/master degree. The prevalence of personal and work-related burnout among paramedics and administrative staff was higher than that seen in doctors and nurses(32,82±3,8 vs32,08±5,0/29,11±4,7 22,33±4,0 vs21,57±3,1/18,89±5,4 19,60±3,9 vs17,26±2,8/15,24±3,7 74,76±10,4 vs70,92±9,5/63,23±12,1).The prevalence of emotional exhaustion and work-related total burnout was significantly higher among doctors, nurses, paramedics, and administrative staff working with direct contact with COVID-19 patients than those among healthcare workers working without direct contact with COVID-19 patients., Conclusion: The present study highlights the impact of the COVID-19 pandemic on healthcare workers., Competing Interests: The authors declare no conflicts of interest., (© 2023 Anastasia-Kiriaki Koutsouri, Despoina Gkentzi.

- Abstract
Background: Prognostic scores can be used to facilitate better management of patients suffering from life-threatening diseases, provided that they have been tested in the population of interest. Aim: To perform external validation of the 4C Mortality Score and PRIEST COVID-19 Clinical Severity Score. Study Design: Prospective observational Study. Methods : Patients hospitalized with COVID-19 pneumonia in a tertiary hospital in Greece were enrolled in the study. The prognostic scores were calculated based on hospital admission data and ROC curve analysis was performed. We assessed a composite outcome of either in-hospital death or need for invasive ventilation. Results : Both 4C and PRIEST scores showed good discriminative ability with an AUC value of 0.826 (CI 95%: 0.765-0.887) and 0.852 (CI 95%: 0.793-0.910) respectively. Based on the Youden Index the optimal cut-off for the 4C score was 11 (Sensitivity 75%, Specificity 75.5%) and 10 for the PRIEST score (Sensitivity 83% and Specificity 69.4%). Calibration was adequate for both scores, except for the low and very high risk groups in the PRIEST score. Conclusion: The 4C Mortality Score and PRIEST COVID-19 Clinical Severity Score can be used for early identification of patients with poor prognosis in a Greek population cohort hospitalized with COVID-19., (© 2022 Themistoklis Paraskevas et al., published by Sciendo.)

- Abstract
Background: Coronavirus disease 2019 (COVID-19) has spread rapidly worldwide with global financial and health care systems consequences. It is already well recognized that immunization against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a precondition for blocking mutations and prevent the emergence of variants. The aim of the study was to investigate the possible relationship between COVID-19 vaccines and the commonly used disease-related blood biomarkers., Methods: Adult patients with confirmed SARS-CoV-2 infection who were hospitalized from November 8, 2021, to December 31, 2021, were included. The retrospective study was conducted in Patras University Hospital, Greece. Two groups of patients were assessed, the ones who were previously vaccinated against SARS-CoV-2 (group A, n = 21), and those who were not (group B, n = 55). After analysis of peripheral blood, we calculated on admission day for each patient the total white blood cell (WBC), absolute lymphocytes count (ALC), absolute monocyte count, D-dimers, C-reactive protein (CRP) plasma levels, lactate dehydrogenase (LDH), ferritin, high-sensitive troponin, as well as the arterial oxygen partial pressure/fractional inspired oxygen (PO
2 /FiO2 ) ratio., Results: The median age of all patients was 65.3 ± 15.2 years old; 68.4% were men and 31.6% were women. Comorbidities were present in 51 patients (67.1%). Hypertension and diabetes were observed as the most common comorbidities (33.3%). About 72.4% of the patients were unvaccinated or have received the first dose of vaccine, and 27.6% were completely vaccinated. No statistical difference was found in the total WBC count and ALC between the two groups (group A vs. group B: 8,168.95 ± 7,584.4 vs. 8,521.9 ± 6,571.3, P = 0.848 and 3,052.1 ± 7,230.7 vs. 1,279.6 ± 1,218.6, P = 0.087). Monocytes count in both groups did not show statistical difference: group A vs. group B: 672.6 ± 384.7 vs. 637.9 ± 477.8 (P = 0.754). Similarly, no difference for D-dimers (1,348.5 ± 1,397.6 vs. 1,850.9 ± 3,877.5, P = 0.575), ferritin (1,082.8 ± 1,399.5 vs. 1,327.4 ± 1,307.8, P = 0.508), high-sensitive troponin (113.6 ± 318.1 vs. 157.5 ± 48.8, P = 0.252), and CRP (6.92 ± 4.9 vs. 7.4 ± 5.9, P = 0.732). For LDH plasma levels, the statistical difference was significant (274.2 ± 85.6 vs. 387.5 ± 223.4, P = 0.003), as well as for the PO2 /FiO2 ratio (355.6 ± 129.7 vs. 260.5 ± 123.3, P = 0,006)., Conclusions: In a mixed population hospitalized for COVID-19, only LDH plasma levels and the PaO2 /FiO2 on admission day showed statistically significant difference between vaccinated and unvaccinated patients. Although unvaccinated patients are more likely to develop severe illness, they did not express significantly higher values of commonly used plasma biomarkers such as ferritin, CRP, and D-dimers which are related to disease severity., Competing Interests: The authors declare that there are no conflicts of interest., (Copyright 2022, Lagadinou et al.)- Published

- Abstract
Diabetes mellitus (DM) and heart failure (HF) are two chronic disorders that affect millions worldwide. Hyperglycemia can induce excessive generation of highly reactive free radicals that promote oxidative stress and further exacerbate diabetes progression and its complications. Vascular dysfunction and damage to cellular proteins, membrane lipids and nucleic acids can stem from overproduction and/or insufficient removal of free radicals. The aim of this article is to review the literature regarding the use of antidiabetic drugs and their role in glycemic control in patients with heart failure and oxidative stress. Metformin exerts a minor benefit to these patients. Thiazolidinediones are not recommended in diabetic patients, as they increase the risk of HF. There is a lack of robust evidence on the use of meglinitides and acarbose. Insulin and dipeptidyl peptidase-4 (DPP-4) inhibitors may have a neutral cardiovascular effect on diabetic patients. The majority of current research focuses on sodium glucose cotransporter 2 (SGLT2) inhibitors and glucagon-like peptide 1 (GLP-1) receptor agonists. SGLT2 inhibitors induce positive cardiovascular effects in diabetic patients, leading to a reduction in cardiovascular mortality and HF hospitalization. GLP-1 receptor agonists may also be used in HF patients, but in the case of chronic kidney disease, SLGT2 inhibitors should be preferred.

- Abstract
Aim: To assess the performance of four novel prognostic scores on admission in predicting in-hospital mortality in patients with confirmed SARS-CoV-2 infection and compare it to NEWS2 and respiratory SOFA score., Methods: A total of 85 adult patients admitted to a tertiary hospital in Western Greece with positive SARS-CoV-2 PCR test, were enrolled and divided into the non-survivor (n = 10) and survivor (n = 75) groups. Receiver Operating Characteristic (ROC) analysis was conducted to determine the predictive effect of the COVID-19 Mortality Score, COVID-19 Severity Index, 4 C Mortality Score and COVID-IRS NLR. Subsequently, they were compared to the respiratory component of the SOFA score and NEWS2., Results: ROC curve analysis showed that the COVID-19 Mortality Score (score ≥4) had the highest combination of sensitivity and specificity values for predicting in-hospital mortality (Sensitivity = 0.8, Specificity = 0.853). The Area Under Curve (AUC) for predicting in hospital mortality for the COVID-19 Mortality Score, COVID-19 Severity Index, 4 C Mortality Score and COVID-IRS NLR were 0.846, 0.815, 0.789 and 0.787, respectively. Comparison between the AUC of the four novel COVID-19 scores, respiratory SOFA and NEWS2 showed no significant differences., Conclusion: All four novel prognostic scores had acceptable to excellent AUC values for predicting in hospital mortality. Out of the four novel prognostic scores for patients with COVID-19, the COVID-19 mortality score showed the best results in our cohort. Its prognostic ability was superior to that of the NEWS2 and respiratory SOFA score.

- Abstract
Aim Several biomarkers are currently used as diagnostic and prognostic tools in patients with cancer. Soluble urokinase plasminogen activator receptor (suPAR) is elevated in acute and chronic inflammatory procedures and several observational studies during the last 20 years have investigated its role in oncology. The purpose of this article was to review the current literature regarding suPAR's role in clinical practice. Methods A systematic literature search of PubMed, Scopus, OpenGrey and Cochrane Library databases through September 2021 was conducted using the following search terms: "supar"or "soluble urokinase plasminogen receptor" and "cancer" or "malignancy". Original articles reporting on suPAR's role in the diagnosis, prognosis and prediction of therapeutic outcomes in patients with confirmed or suspected cancer were included. Results Among 45 found articles, the most were observational cohort studies. The included studies were further categorized by cancer site. SuPAR level was higher in patients with cancer compared to healthy controls, but its diagnostic and prognostic accuracy differs depending on the site of cancer. Conclusion SuPAR has promising aspects in the field of oncology and public health and future research should further investigate its use in clinical practice. As it is elevated in different types of cancer, it could potentially serve as an adjunctive tool for the mass screening of patients with non-specific signs of cancer, but larger cohort studies that support these findings must be conducted., (Copyright© by the Medical Assotiation of Zenica-Doboj Canton.)

- Abstract
Introduction: Oxygen therapy remains the cornerstone for managing patients with severe SARS-CoV-2 infection and several modalities of non-invasive ventilation are used worldwide. High-flow oxygen via nasal canula is one therapeutic option which may in certain cases prevent the need of mechanical ventilation. The aim of this review is to summarize the current evidence on the use of high-flow nasal oxygen in patients with severe SARS-CoV-2 infection., Material and Methods: We conducted a systematic literature search of the databases PubMed and Cochrane Library until April 2021 using the following search terms: "high flow oxygen and COVID-19" and "high flow nasal and COVID-19"., Results: Twenty-three articles were included in this review, in four of which prone positioning was used as an adjunctive measure. Most of the articles were cohort studies or case series. High-flow nasal oxygen therapy was associated with a reduced need for invasive ventilation compared to conventional oxygen therapy and led to an improvement in secondary clinical outcomes such as length of stay. The efficacy of high-flow nasal oxygen therapy was comparable to that of other non-invasive ventilation options, but its tolerability is likely higher. Failure of this modality was associated with increased mortality., Conclusion: High flow nasal oxygen is an established option for respiratory support in COVID-19 patients. Further investigation is required to quantify its efficacy and utility in preventing the requirement of invasive ventilation.

- Abstract
Reliable biomarkers are necessary for the risk stratification of patients infected with SARS-CoV-2. This novel coronavirus is now established to affect several organs in addition to the lungs, most prominently the heart. This is achieved through direct damage to the myocardium and indirect immune-associated effects during the cytokine storm. We performed a literature review aiming to identify the prognostic value of alterations of cardiac biomarkers in SARS-CoV-2 infection. Cardiac biomarkers are significantly elevated in patients with severe COVID-19 and are independent predictors of mortality. High-sensitivity troponin I and T are correlated with multiple inflammatory indexes and poor outcomes. Although cut-off values have been established for most of cardiac biomarkers, lower limits for troponins may have better prognostic values and longitudinal monitoring of cardiac biomarkers can help the clinician assess the patient's course. Additional measurements of NT-proBNP, can detect the subgroup of patients with poor prognosis., (© 2022 Eleousa Oikonomou et al., published by Sciendo.)

- Abstract
Background: Sepsis remains a major public health problem with increased incidence of mortality. As early recognition and prompt treatment in the first 'golden hour' remain the cornerstone of the septic patient approach, there is a real need for rapid and cost-effective reliable markers., Objective: The aim of the study was to evaluate the neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte percentage ratio (PL%R) in patients with sepsis who were initially treated in the Emergency Department and investigate their predictive ability regarding in-hospital mortality and performance comparing them to SOFA, APACHE II, and SAPS II score., Methods: A retrospective observational study in the Emergency Department and Internal Medicine Department in a Mediterranean University Hospital. A total of forty-three patients suffering from sepsis were enrolled in the study. Demographic information, past medical history with pre-existing co-morbidities, physical examination findings, and radiological data were reviewed. Neutrophil to lymphocyte ratio and platelets to lymphocyte percentage ratio was calculated from the complete blood count (CBC). Disease severity was evaluated by calculating SOFA, SAPS II and APACHE II score on admission. The outcome of patients was noted as a primary endpoint., Results: Values of NLR and PL%R were statistically significantly higher in the group of non-survivors and correlate with sepsis prognostic scores., Conclusion: Calculation of NLR and PL%R is easy, fast, and inexpensive in the assessment of patients with sepsis. Their role as prognostic indexes and their validity in the Emergency Department setting should be evaluated with large prospective studies., Competing Interests: There are no conflicts of interest., (© 2022 Vasileios Karamouzos, Themistoklis Paraskevas, Francesk Mulita, Sofia Karteri, Eleousa Oikonomou, Nikolaos Ntoulias, Nikolaos Dimitrios Pantzaris, Vayanna Bourganou, Dimitrios Velissaris.)

- Abstract
Aim COVID-19 pandemic caused by SARS-CoV-2 is spreading throughout the world affecting both healthy individuals and people with underlying immune-deficiencies. People living with human immunodeficiency virus (HIV) consist a group multiply affected by this universal crisis. Methods Literature search aiming to identify relevant publications referring to the consequences of the COVID-19 pandemic in HIV infected population. Results A body of literature is rapidly growing in regard to epidemiological data, the interaction between HIV and SARS-CoV-2, and clinical outcome in people living with HIV. Intensive research is warranted to identify any interactions of the co-existence of the two viruses in the immune system of HIV infected patients as common pathophysiology and molecular aspects are recognized. Human relations are diminished as a result of the social measures, and detailed recording of the consequences in this population is needed. Conclusion Further research could shed light on the common underlying molecular mechanisms of both conditions in an attempt to discover treatment regimens for SARS-CoV-2 infection., (Copyright© by the Medical Assotiation of Zenica-Doboj Canton.)

- Abstract
Aims: To evaluate the prevalence of X-ray findings in hospitalized patients requiring hospitalization with suspected Coronavirus disease 2019 (COVID-19) infection and potential differences in the laboratory values and clinical outcomes related to the presence of abnormal chest X-ray (CXR) findings., Methods: A total of 117 patients suspected of COVID-19 pneumonia and hospitalized with symptoms of lower respiratory tract disease were included in this study. Patients were divided into subgroups according to COVID-19 diagnosis and statistical comparisons were made according to CXR findings., Results: In our cohort, CXR abnormalities were more common in patients with confirmed COVID-19 diagnosis and were associated with increased mortality. Patients with abnormal chest X-rays had a significantly lower PaO
2 /FiO2 ratio both in the COVID-19 and non-COVID-19 groups., Conclusion: CXR is a routine examination in all patients with symptoms of lower respiratory tract disease and its findings relate to in-hospital mortality and PaO2 /FiO2 ratio. Thus, it can be a significant measure of disease severity, especially in resource restrained settings and emergency situations such as the COVID-19 pandemic., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2021, Velissaris et al.)- Published

- Abstract
Background: The respiratory system is the main system affected by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and a great number of infected people need hospitalization. Soluble urokinase plasminogen activator receptor (suPAR) is a biomarker indicative of acute and chronic inflammation. Current literature supports that suPAR has great predictive ability for mortality in patients with coronavirus disease 2019 (COVID-19). The aim of this study was to compare the value of suPAR and other laboratory biomarkers in patients with chest infection and suspected COVID-19., Methods: A total of 41 consecutive patients with chest infection were enrolled in the study and were assigned into two groups according to the real-time polymerase chain reaction (PCR) result for SARS-CoV-2. The two groups had no significant difference in baseline data (age, sex), arterial oxygen partial pressure (PO
2 )/fraction of inspired oxygen (FiO2 ) ratio and mortality., Results: Among patients with chest infection who required hospitalization, suPAR was significantly higher on admission in those with COVID-19 when compared to patients with non-COVID-19. suPAR had a great prognostic ability for in-hospital mortality in the COVID-19 subgroup., Conclusions: A single measurement of suPAR on admission can provide prognostic information for patients with suspected COVID-19 pneumonia. In the subgroup of patients with positive real-time PCR result for SARS-CoV2, suPAR was significantly higher and had an excellent prognostic value for the in-hospital mortality., Competing Interests: The authors have no conflict of interest to declare., (Copyright 2021, Velissaris et al.)- Published

- Abstract
Sepsis and septic shock are considered major factors in the development of myopathy in critically ill patients, which is correlated with increased morbidity rates and ICU length of stay. The underlying pathophysiology is complex, involving mitochondrial dysfunction, increased protein breakdown and muscle inexcitability. Sepsis induced myopathy is characterized by several electrophysiological and histopathological abnormalities of the muscle, also has clinical consequences such as flaccid weakness and failure to wean from ventilator. In order to reach definite diagnosis, clinical assessment, electrophysiological studies and muscle biopsy must be performed, which can be challenging in daily practice. Ultrasonography as a screening tool can be a promising alternative, especially in the ICU setting. Sepsis and mechanical ventilation have additive effects leading to diaphragm dysfunction thus complicating the patient's clinical course and recovery. Here, we summarize the effects of the septic syndrome on the muscle tissue based on the existing literature., (© 2021 Eleousa Oikonomou et al., published by Sciendo.)
