Diagnostic and predictive value of Respiratory Index of Severity in Children (RISC) scoring system in community-acquired pneumonia: a prospective cross sectional study

Abstract Background Community-acquired pneumonia (CAP) exhibits high mortality rates among children, accounting for up to 50% in severe cases. Respiratory Index of Severity in Children (RISC) score is a six-predictor standardized means for assessment of the severity of respiratory illness among children. The aim of this study was to validate the RISC score in evaluation of mortality outcome in hospitalized infants diagnosed with CAP. Methods This prospective cross-sectional study was conducted on 150 Egyptian children who were diagnosed to have CAP, admitted to the general wards and pediatric intensive care units (PICUs) of Cairo University Children Hospital, Faculty of Medicine, Cairo University from September 2019 to June 2020. Results Median RISC score was significantly higher in non-survivors compared with survivors (p  3). The RISC score was a significant predictor for mortality in infants with CAP (Odds ratio = 5.17, p < 0.001). Conclusion The RISC score helps in prediction of mortality among children with CAP. Future studies are needed to validate RISC score as a guide for effective management protocol

Clinico-laboratory outcomes of plasma transfusion in the Egyptian’s pediatric intensive care units—a prospective observational study

Abstract Background Despite the paucity of data supporting their indications, plasma transfusions (PT) are regularly administered for critically ill patients (CIP) in pediatric intensive care units (PICU). The aim of this study was to identify the actual indications for PT in the Egyptian’s PICUs and determine to what extent it affects the clinic-laboratory outcomes for CIP. Methods A prospective observational study was conducted for 6 months on 180 CIP in PICUs of Cairo University Hospital who received plasma for at least one time during their length of stay (LOS). Full history, examination, and investigations were obtained from the medical records. Results Plasma was transfused in 64.4% of the studied population to support moderate and severe critical illness identified by multiple organ dysfunction score (MODS). Meanwhile, subjective-based physician conceptions accounted for 12.8% of all indications for plasma transfusion. PT in CIP was associated with a significant reduction in platelet count, prothrombin time, partial thromboplastin time, and international normalized ratio with p-value < 0.001, while there was a significant increase in hemoglobin level with p-value < 0.001. A statistically positive correlation exists between the time interval between admission and 1st PT and LOS with a p-value < 0.001 being shorter with earlier transfusion. Of the 180 patients enrolled in this study, seventy patients (38.9%) died, while 110 patients (61.1%) survived. A statistically significant increase in mechanical ventilation (MV) (p = 0.004), total number of PT (p < 0.001), and MODS score (p < 0.001) were recorded in dead CIP compared with survivors. Conclusion Moderate and severe critical illness identified by MODS was the most frequent cause for PT in the Egyptian’s PICUs. Early, precise, and objectively based PT has a strong role in improving the outcomes in CIP

Dental pulp stem cells ameliorate D-galactose-induced cardiac ageing in rats

Background Ageing is a key risk factor for cardiovascular disease and is linked to several alterations in cardiac structure and function, including left ventricular hypertrophy and increased cardiomyocyte volume, as well as a decline in the number of cardiomyocytes and ventricular dysfunction, emphasizing the pathological impacts of cardiomyocyte ageing. Dental pulp stem cells (DPSCs) are promising as a cellular therapeutic source due to their minimally invasive surgical approach and remarkable proliferative ability. Aim This study is the first to investigate the outcomes of the systemic transplantation of DPSCs in a D-galactose (D-gal)-induced rat model of cardiac ageing. Methods. Thirty 9-week-old Sprague-Dawley male rats were randomly assigned into three groups: control, ageing (D-gal), and transplanted groups (D-gal + DPSCs). D-gal (300 mg/kg/day) was administered intraperitoneally daily for 8 weeks. The rats in the transplantation group were intravenously injected with DPSCs at a dose of 1 × 106 once every 2 weeks. Results The transplanted cells migrated to the heart, differentiated into cardiomyocytes, improved cardiac function, upregulated Sirt1 expression, exerted antioxidative effects, modulated connexin-43 expression, attenuated cardiac histopathological alterations, and had anti-senescent and anti-apoptotic effects. Conclusion Our results reveal the beneficial effects of DPSC transplantation in a cardiac ageing rat model, suggesting their potential as a viable cell therapy for ageing hearts
