BackgroundPublished data regarding the impact of obesity on COVID-19 outcomes are inconsistent. However, in most studies, body composition was assessed using body mass index (BMI) alone, thus neglecting the presence and distribution of adipose tissue. Therefore, we aimed to investigate the impact of body and visceral fat on COVID-19 outcomes.MethodsObservational, prospective cohort study included 216 consecutive COVID-19 patients hospitalized at University Clinical Center Kragujevac (Serbia) from October to December 2021. Body composition was assessed using the BMI, body fat percentage (%BF), and visceral fat (VF) via bioelectrical impedance analysis (BIA). In addition to anthropometric measurements, variables in the research were socio-demographic and medical history data, as well as admission inflammatory biomarkers. Primary end-points were fatal outcomes and intensive care unit (ICU) admission.ResultsThe overall prevalence of obesity was 39.3% according to BMI and 50.9% according to % BF, while 38.4% of patients had very high VF levels. After adjusting odds ratio values for cofounding variables and obesity-related conditions, all three anthropometric parameters were significant predictors of primary end-points. However, we note that % BF and VF, compared to BMI, were stronger predictors of both mortality (aOR 3.353, aOR 3.05, and aOR 2.387, respectively) and ICU admission [adjusted odds ratio (aOR) 7.141, aOR 3.424, and aOR 3.133, respectively].ConclusionObesity is linked with COVID-19 mortality and ICU admission, with BIA measurements being stronger predictors of outcome compared to BMI use alone.
Background and Objectives: Oral disorders, frequently observed in patients with primary Sjögren’s syndrome, can profoundly affect patients’ daily lives and well-being, as oral health represents a fundamental part of general health. Saliva plays an essential part in maintaining and protecting oral health, so the decrease in its quantity and quality leads to chronic oral discomfort alongside a broad spectrum of problems. The objective of the present study was to evaluate the oral health of patients with primary Sjögren’s syndrome and establish its effect on the different domains of their oral health-related quality of life (OHRQoL). Materials and Methods: The research was designed as an observational case–control study with prospective data collection. Eighty patients, divided into two groups based on their oral status, participated in the study. All subjects underwent a complete oral examination. The OHRQoL was assessed using the Oral Health Impact Profile-14 (OHIP-14). Results: The most prevalent oral manifestation was exfoliative cheilitis, while 30% of subjects complained of chewing and swallowing difficulties. The OHIP-14 summary score was significantly higher in the patients with oral lesions (26.0 (5.0) vs. 17.0 (4.0), respectively; p < 0.001). Oral manifestations, systemic involvement, medication, and periodontal indexes were significantly associated with OHIP-14 scores. Conclusions: Patients with oral alterations had a substantially decreased OHRQoL. These findings emphasize the importance of oral diseases for patients’ well-being. Therefore, it is essential for dentists to be included in the multidisciplinary teams managing primary Sjögren’s syndrome, as improving patients’ oral status would lead to better oral health and enhanced OHRQoL.
This study aimed to provide additional information on the influence of perinatal factors on fecal (f)-calprotectin values in preterm infants. Calprotectin was determined from the first spontaneous stool (analyzed on the Alegria device by using the enzyme-linked immunosorbent assay [ELISA] method) obtained from neonates at a mean age of 3.41 ± 2.44 days of life. We analyzed 114 subjects who had a body weight of 1847.67 ± 418.6 g and were born at a gestational age of 32.6 ± 2.43 weeks, without intestinal and other congenital anomalies or any diseases other than those related to premature birth. The values of f-calprotectin are in a positive correlation with female subjects, intrauterine growth restriction, significant ductus arteriosus, enteral feeding intolerance, postnatal prolonged use of broad-spectrum antibiotics, and values of bicarbonates (analyzed in a sample of capillary arterial blood). Measurement of f-calprotectin in the first 7 days after birth can help to early detect the intestinal distress or early staging of necrotizing enterocolitis in premature infants.
(1) Background: the purpose of this study was a preliminary analysis of current methods of online teaching at the Faculty of Medical Sciences, University of Kragujevac, Republic of Serbia, in order to define the attitudes of biomedical students about education during the COVID-19 pandemic and to validate of the education medical questionnaire (eMedQ), a new tool for the assessment of the students’ perceptions about digital education. (2) Methods: this was a qualitative cross-sectional observational study that used the originally developed 45-item questionnaire (eMedQ) as an assessment instrument conducted on biomedical students (n = 209) of all study years at the Faculty of Medical Sciences, University of Kragujevac (Republic of Serbia), during winter semester or between September 2021 and January 2022. (3) Results: In this study, a Cronbach’s alpha value of 0.904 was obtained, which indicated good internal consistency; the correlation matrix revealed many coefficients greater than 0.3, denoting high correlations between the items. The Kaiser–Meyer–Olkin measure of sampling adequacy was 0.866 and Bartlett’s test of sphericity was significant (p < 0.001). The PCA revealed the presence of seven components with characteristic values over one, while three factors explained the highest percentage of variance. (4) Conclusions: this research developed and validated a new tool for evaluation of biomedical student perceptions about digital education.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
