The blood flow rate on the first day after arteriovenous fistula creation is a predictor of successful fistula maturation.

BACKGROUND: The determination of blood flow rate (BFR) is a useful tool for assessing the function of arteriovenous fistula (AVF). METHODS: Eighty patients with a newly created radio cephalic AVF were analyzed. Hemodynamics and morphological characteristics of the blood vessels were assessed by Doppler ultrasound. RESULTS: The mean age of patients was 59.9 ± 13.5 years. A successful rate of AVF maturation was 62.5% at 8 weeks. Six adjusted models of multivariate analysis showed that BFR at Day 1 was a predictor for AVF maturation both at 4 weeks (p < 0.001) and 8 weeks (p < 0.001). Receiver operating characteristic analysis showed an optimal cut-off point for BFR at Day 1 of 395 ml/min for successful maturation at 4 weeks (sensitivity 0.714, specificity 0.889) and 344 ml/min for successful maturation at 8 weeks (sensitivity 0.860, specificity 0.867). CONCLUSION: BFR at Day 1 is a powerful predictor for successful AVF maturation at 4 and 8 weeks.

Comorbid Conditions in a Cohort of Inpatients with SARS-CoV-2 and their Association with In-Hospital Mortality During the Early Phases of the Pandemic.

Introduction: Studies determined that age and associated comorbidities are associated with worse outcomes for COVID-19 patients. The aim of the present study is to examine previous electronic health records of SARS-CoV-2 patients to identify which chronic conditions are associated with in-hospital mortality in a nationally representative sample. Materials and Methods: The actual study is a cross-sectional analysis of SARS-CoV-2 infected patients who were treated in repurposed hospitals. The study includes a cohort of patients treated from 06-11-2020 to 15-03-2021 for COVID-19 associated pneumonia. To examine the presence of comorbidities, electronic health records were examined and analyzed. Results: A total of 1486 in-patients were treated in the specified period, out of which 1237 met the criteria for case. The median age of the sample was 65 years. The overall in-hospital mortality in the sample was 25.5%, while the median length of stay was 11 days. From whole sample, 16.0% of the patients did not have established diagnoses in their electronic records, while the most prevalent coexisting condition was arterial hypertension (62.7%), followed by diabetes mellitus (27.3%). The factors of age, male gender, and the number of diagnoses showed a statistically significant increase in odds ratio (OR) for in-hospital mortality. The presence of chronic kidney injury was associated with the highest increase of OR (by 3.37) for in-hospital mortality in our sample. Conclusion: The study reaffirms the findings that age, male gender, and the presence of comorbidities are associated with in-hospital mortality in COVID-19 treated and unvaccinated patients. Our study suggests that chronic kidney injury showed strongest association with the outcome, when adjusted for age, gender, and coexisting comorbidities.

Social distance and stigma towards persons with serious mental illness among medical students in five European Central Asia countries.

The study investigated behavioral measures of social distance (i.e., desired proximity between self and others in social contexts) as an index of stigma against those with mental illness among medical students in the Republic of North Macedonia, Turkey, Azerbaijan, Kazakhstan, and Poland, using the Reported and Intended Behavior Scale (RIBS), a standardized, self-administered behavioral measure based on the Star Social Distance Scale. The students' responses to standardized clinical vignettes on schizophrenia, and depression with suicidal ideation, were also assessed. A total of 257 North Macedonian (females, 31.5%; 1-4 grades, 189; 5-6 grades, 68); 268 Turkish (females, 43.3%; 1-4 grades, 90; 5-6 grades, 178); 450 Kazakh (females, 28.4%, 71.6%; 1-4 grades, 312; 5-6 grades, 138); 512 Azerbaijani (females, 24%; 1-4 grades, 468; 5-6 grades, 44; females, 24%), and 317 Polish (females, 59.0%; 1-4 grades, 208; 5-6 grades, 109) students were surveyed. The responses on the RIBS social distance behavior measures did not improve with advancing medical school grade, but students across all sites viewed schizophrenia and depression as real medical illnesses. The results support the development of enhanced range of integrated training opportunities for medical student to socially interact with persons with mental illness sharing their experiences with them.
