Assessment of mental health and quality of life among children with congenital heart disease.

PURPOSE: The current study aimed to determine the prevalence of specific psychiatric disorders, identify predictors associated with these disorders, and assess the quality of life (QoL) among children with congenital heart disease. METHODS: This comparative cross-sectional study was conducted in the National Heart Institute outpatient clinics. It included 204 children with structural congenital heart defects (CHD). In addition to assessing QoL with the Pediatric Quality of Life Inventory scale, the Mini-International Neuropsychiatric Interview for Children and Adolescents was utilized to identify psychiatric disorders in the children studied. RESULTS: Children with CHD were at increased risk for mood and anxiety disorders. They were also more susceptible to obsessive-compulsive disorder than the comprative healthy group. In children with CHD, the cyanotic group demonstrated a greater decrease in QoL than the acyanotic group. CONCLUSION: Children with CHD have an increased risk of psychiatric disorders and a lower overall QoL score.

Prognostic utility of MicroRNA-221 and interleukin-6 in cerebral ischemic stroke.

Cerebral ischemic stroke has a significant mortality rate and persistent impairment. The initial diagnosis of stroke occurs by magnetic resonance imaging and computed tomography. There is a strong need for more accessible, less expensive, and non-invasive methods besides the neuroimaging methods. MicroRNAs (miRNAs) are critical regulators for ischemic stroke as they are involved in stroke pathophysiology. The goal of the current study was to determine whether microRNA-221 (miR-221) could be used as a diagnostic biomarker for patients with ischemic stroke, and whether it can serve as a promising indicator of the disease severity especially if combined with interleukin-6 (IL-6). The study included 90 subjects, 45 cerebral ischemic stroke patients and 45 controls. MiR-221 was evaluated by quantitative real-time polymerase chain reaction (q-PCR) and IL-6 by enzyme-linked immunosorbent assay (ELISA). Our study results revealed that the serum miR-221 level was significantly reduced in cerebral ischemic stroke patients when compared to the control group (p<0.0001). In addition, serum miR-221 showed a significant negative correlation with cerebral stroke severity (p<0.0001), whereas serum IL-6 showed a significant positive correlation with cerebral stroke severity (p < 0.0001). We also analyzed the receiver operator characteristic (ROC) curve and found that area under the ROC curve (AUC) for severity of ischemic stroke by miR-221 was 0.97 (95% confidence intervall0.93-1, p<0.001). Notably, the combination of serum miR-221 with IL-6 for prediction of ischemic stroke severity showed both increased sensitivity/specificity (AUC=0.99, 95% confidence interval 0.96-1, p<0.001) than miR-221 alone. We concluded that miR-221 constituted a non-invasive, sensitive, and specific biomarker that could be used for diagnosis of ischemic stroke and for prediction of its severity.

Oxidative stress and early mortality in acute ischemic stroke: A prospective cohort study.

BACKGROUND: Malondialdehyde (MDA) is an oxidative stress biomarker, which represents a unifying mechanism of brain injury that occurs throughout the ischemic stroke cascade. The current study aimed to examine whether or not acute ischemic stroke (AIS) patients who had elevated serum MDA levels at admission had an increased risk of mortality and a worse functional outcome three months later. METHODS: An observational, prospective cohort study that enrolled 90 patients with AIS. The patients were examined in the first 24 hours and then followed up for three months to assess mortality, short-term neurological functional outcome, and neurological disability by the Modified Rankin Scale (MRS). RESULTS: The mean of serum MDA level among AIS patients was 6.3 ± 3.7 nmol/ml. Non-survivor cases were associated with statistically significantly higher serum MDA levels compared to survivors (9.7 ± 4.3 vs. 5.3 ± 2.8, p < 0.001), respectively. Patients with severe stroke, according to NIHSS score, were associated with significantly (p < 0.05) higher MDA levels compared to moderate and mild cases (7.4 ± 4.3 vs. 5.4 ± 2.6 vs. 3.3 ± .6). At a cutoff point of ≥ 6.7 nmol/ml, the area under the curve (AUC) for serum MDA levels as a predictor of mortality was 0.8 (0.69-0.91; p < 0.05). The sensitivity, specificity, positive predictive value, and negative predictive value were 77%, 80%, 89.5%, and 48.5%, respectively. Multivariate regression demonstrated that MDA level was a significant independent predictor of mortality among patients with AIS (OR = 1.29, 95% CI: 1.01 to 1.65; p = 0.041). CONCLUSION: MDA serum level was significantly higher in non-survivors than in survivors patients, so MDA could be used as a predictor for early mortality and short-term outcome of cases with AIS.

Skin-to-skin contact and its effect on mothers' postpartum psychological distress and their full-term neonate in Egypt.

DESIGN: A randomized controlled study was conducted on 400 mothers, who were divided into two groups: 200 mothers who applied skin-to-skin infant care (SSC) for at least 1 h daily for 12 weeks and 200 mothers who performed the usual mother-infant care. The mothers were recruited from the Obstetric Department of Al-Zahraa University Hospital in Cairo, Egypt. The enrolled mothers' infants were assessed for body weight. Sleep hours and frequency of breast milk feeding were evaluated by the mother during the day. All of the mothers who took part in the study were assessed for postoperative pain, wound healing, postpartum depression, anxiety, sleep quality and newborn maternal bonding. RESULTS: There was a significant increase in frequencies of breastfeeding and the body weight at 12 weeks' postnatal age and also an increase in sleep hours in the infants who had SSC. The mothers who performed SSC had good sleep quality in comparison with those who performed the usual infant care; in addition, they had less postoperative pain intensity and proper wound healing apart from better maternal-infant bond, decreased anxiety and decreased depression frequency. CONCLUSION: SSC was associated with better infant breastfeeding, increased sleep hours in infants and less postpartum psychological burden in mothers.

COVID-19 Vaccination Perception and Acceptance Among Female Medical and Nursing Students at Al-Azhar University, Egypt.

Background: There are still many concerns related to various types of COVID-19 vaccines, which may result in individuals' hesitancy presenting a problem for public health authorities to achieve coverage for population immunity. As trustworthy health-care workers, medical and nursing students' perception towards COVID-19 vaccines may greatly influence the future population's uptake of vaccines; however, studies related to the vaccine acceptance rates among them are limited. Objective: To identify the perception of medical and nursing students toward COVID-19 vaccines and the factors acting either as motivators or barriers to be vaccinated. Methods: A cross-sectional comparative study was conducted on 500 undergraduate students aged ≥18 years from medical and nursing faculties. Data were collected via a semi-structured self-administered questionnaire that consisted of questions on general characteristics of the participants and source of information about the vaccine. Also, it includes items assessing the perception and acceptance of COVID-19 vaccines. Descriptive statistics, chi-squared, t-test and multiple logistic regressions were performed using SPSS version 22. Results: Positive perception was detected among more than half of overall students. Although medical students had significant higher positive perception toward COVID-19 vaccines than nursing students (54.9% vs. 41.1%, p <0.05), they were more hesitant to get vaccinated than nursing students (25.7% vs. 19.6%, p >0.05). While, medical students had a higher intention to encourage family members or friends to get vaccinated than did nursing students (47.7% vs .43.8%, respectively) (p >0:05). Furthermore, participants were more likely to accept vaccination if they reported higher levels of positive perception especially for vaccine safety and increasing recovery rate. Conclusion: Academic medical and nursing leaders should consider female students' vaccine concerns, and future efforts are needed to reduce their hesitancy and raise awareness about vaccinations that may eventually improve perception and acceptance of COVID-19 vaccines.

Impact of Toll-Like Receptor 2 and 9 Gene Polymorphisms on COVID-19: Susceptibility, Severity, and Thrombosis.

Background: Toll-like receptors (TLRs) play an important role in activation of innate and adaptive immune responses. Aim: We aimed to detect the association between TLR2 rs5743708 G>A and TLR9 rs5743836 C>T variants and COVID-19 disease susceptibility, severity, and thrombosis by using neutrophil extracellular traps (NETs). Subjects and Methods: We included 100 adult COVID-19 patients as well as 100 age- and gender-matched normal controls. Participants were genotyped for TLR2 rs5743708 and TLR9 rs5743836. Citrullinated Histone (H3) was detected as an indicator of NETs. Results: The mutant (G/A and C/C) genotypes and (A and C) alleles of TLR2 rs5743708 and TLR9 rs5743836, respectively, have been significantly related to a higher risk of COVID-19 infection, representing a significant risk factor for the severity of COVID-19. There was no significant association between the two variants and citrullinated histone (H3). Conclusion: TLR2 rs5743708 and TLR9 rs5743836 variants have been significantly related to a higher risk and severity of COVID-19 infection but had no effect on thrombus formation.

The Influence of Smoking on Renal Functions Among Apparently Healthy Smokers.

Background: Cigarette smoking is an important modifiable risk factor in kidney disease progression. Although long-term smoking has been associated with chronic kidney disease (CKD), its effect on kidney function in early stages has not been clarified. Objective: To detect the early effects of smoking either active or passive on kidney functions. Methodology: The current study was comparative cross sectional study conducted on 280 participants, 140 were non­smokers and 140 were smokers (70 passive smokers and 70 active smokers). The two groups were comparable in terms of all parameters. We investigated the possible effects of smoking on kidney functions using both serum kidney function tests especially; serum urea, serum creatinine, serum cotinine levels and detection of albumin in urine. Smoking history, full Laboratory investigations, Ventilatory function test including (FEV1/FVC, FEV1, FEF 25-75%, VC and FVC) were done. Results: Serum urea, serum creatinine, serum cotinine levels and urinary albumin were statistically significant higher in smokers group in comparison to nonsmokers, also the serum cotinine levels and urinary albumin were statistically significant in active smokers in comparison to passive smokers. There were positive correlations between the level of urinary albumin and pack/year (r = 0.9, p<0.05), smoking index (r = 0.9, p<0.05), smoking duration (r = 0.4, p<0.05), and serum cotinine (r = 0.6, p<0.050) with good statistical significance. The most significant predictive risk factors of microalbuminuria among smokers group in descending orders were active smoking, passive smoking, age and serum cotinine level. Conclusion: Both active and passive smoking, especially among heavy smokers, is a significant risk factor for microalbuminuria. This finding increase the importance of early cessation of smoking in order to minimize early renal affection among healthy smokers that may not be discovered by routine renal function tests.
