Abstract Background There have been approximately 158 million coronavirus disease 2019 (COVID-19) pandemic survivors worldwide by June 9, 2021. As a result, concerns about hair loss in COVID-19 patients have emerged among dermatologists. However, most of extant literature have limited implications by relying on cross-sectional studies with restricted study subjects without control group. Therefore, our study aims to investigate the risk of developing alopecia areata (AA) among COVID-19 patients in South Korea using adequate control based on national representative data. Methods We used the National Health Insurance Service (NHIS) COVID-19 cohort database, comprising COVID-19 patient and control group, all of whom were diagnosed from January 1, 2020 to June 4, 2020. Patients were defined as individuals who were confirmed as COVID-19 positive, regardless of disease severity. Controls were defined as whom confirmed as COVID-19 negative. People with a history of AA during the period 2015–2019 were excluded. The primary endpoint was a new diagnosis of AA (ICD-10-CM-Code: L63). Adjusted incidence rate ratio (IRR) of developing AA was estimated using log-link Poisson regression model based on incidence density of case and control group. The model adjusted for (1) age and sex (2) demographic variables (age, sex, place of residence, and income level). Statistical significance was set at p< 0.05. Results A total of 226,737 individuals (7,958 [3.5%] cases and 218,779 [96.5%] controls) were included in the final analysis. There were more females than males, both in test positives and negatives at 59.9% and 52.3%, respectively. The largest test positive population was those in age group 20 to 29 years (25.5%),. The test negatives had the largest population in age group 30 to 39 years (17.1%). The ratio of newly diagnosed AA was 18/7,958 (0.2%) in cases and 195/218,779 (0.1%) in controls. IRRs of COVID-19 patients having newly diagnosed AA compared to controls were 0.78 (0.48‒1.27) when age and sex were adjusted for, and 0.60 (0.35‒1.03) when all demographic variables were adjusted for. Flowchart of study subject selection Conclusion Diagnosis of COVID-19 was not significantly associated with development of AA even after appropriately adjusting for covariates.

The study was conducted to know whether bulk inflow of Non Emergency Calls (NECs) acts as an independent predictor for depression in call handlers of Rescue 1122, Punjab, Pakistan. Forty five (45) call handlers were recruited from evening shift of 9 districts. Similarly, same-sized control group was made out of field rescuers. The groups were compared for rate and severity level of depression using Beck’s Depression Inventory-II (BDI-II; Beck, Steer, & Brown, 1996). Probable predictors (except workplace stress) for depression in call handlers were evaluated through risk estimates. For workplace stress, a purposefully developed close- ended Workplace Stress Questionnaire including two subscales i.e. Non Emergency call and Control Room Environment of 30 items each was administrated. Twenty nine (64.4%) subjects of study group reported depression on BDI. Consequently, the same group had significantly higher mean depression score than control (18.2 vs. 12.6; p = .00). The scores also showed insignificant association with any of the probable predictors (demographic variables) of the call attendees. The respondents perceived more occupational stress against NECs. The findings attract the attention of authorities towards the severity of the concern.

Introduction: Asthma in children often leads to behavioural problems due to the chronic nature of the disease. Parents also tend to be overprotective and many may not even consult a doctor for the same. The objectives were to study the various behavioural problems seen in children having asthma as compared to those with minor ailments, parental awareness about the same and their parenting styles.Material and Methods: 75 parents of children of bronchial asthma and 75 parents of children having short term minor ailments formed the asthma and control groups respectively. The Behaviour Problem Index was used to assess the behavioural problems in children as documented by parents and parental overprotectivenesswas assessed using the Vulnerable Child/ Overprotecting Parent Scale.Results:The demographic variables were comparable in both the groups. Behavioural problems on all domains and parental over protectiveness in the asthma group were found to be statistically significant as compared to control group. However there was no significant correlation between the parental over-protectivenessand the behavioural problems in both the groups.Conclusions: Early referral to the psychiatrist with parental counselling will result in better outcomes for the child.J Nepal Paediatr Soc 2016;36(3):232-237

Onychophagia and onychotillomania are rarely seen in clinical practice and are considered undervalued. The study aims were to determine the prevalence of onychophagia and onychotillomania habit in the patient group with hand nail damage and control group, to determine which would be the target population to educate. Patients were interviewed about self-destructive habits. Excel and SPSS were used for data analysis. In the nail damage group, 28.6% of the respondents showed self-destructive habits and past habits – 31.4%. In the control group, the result was 22.9% and 31.4%. For 74.3% of patients the cause of nail damage was skin disease (including 61.54% of respondents with nail damage who have psoriasis), for 5.7% it was age-related nail changes, for 20% traumatic damage and for 57.14% of them it was a result of self-destructive habit. In the nail damage group both – present and past self-destructive habits are higher than in the control group, but it has no statistical significance (p=0.785). 1)The prevalence of onychophagia and onychotillomania does not differ between patients and control group. 2)General education of the population is necessary to actualize this problem, which can worsen nail changes.

Background Antioxidants show nephroprotective effect against vancomycin associated nephrotoxicity (VAN) in animals. This study aimed to assess the ascorbic acid nephro-protective role against VAN clinically. Methods Forty-one critically ill patients were randomly assigned to one of two groups: intervention group (vancomycin IV plus ascorbic acid, n=21) or control group (vancomycin IV only, n=20). Primary outcomes were the incidence of VAN and the absolute change in creatinine parameters, while mortality rate was the secondary outcome. Nephrotoxicity was defined as an increase in serum creatinine (S.cr) by at least 0.5 mg/dL or 50% of baseline for at least two successive measurements. This study is registered at Clinicaltrials.gov (NCT03921099), April 2019. Results Mean absolute S.cr increase was significant when compared between both groups, P-value = 0.036, where S.cr increased by 0.05(0.12) and 0.34(0.55) mg/dL in the intervention and control groups, respectively. Mean absolute Cr.cl decline was significant when compared between both groups, P-value = 0.04, where Cr.cl was decreased by 5.9(17.8) and 22.3(30.4) ml/min in the intervention and control groups, respectively. Incidence of VAN was 1/21(4.7%) versus 5/20(25%) in the intervention and control groups, respectively (RR: 0.19; CI: 0.024–1.49; P-value = 0.093). Mortality was higher in the control group; however, it was not statistically significant, P-value = 0.141. Conclusion Co-administration of ascorbic acid with vancomycin preserved renal function and reduced the absolute risk of VAN by 20.3%, however, the reduction in VAN incidence didn’t reach statistical significance level. Further large multicenter prospective trials are recommended.

Background: Undiagnosed atrial fibrillation (AF) may cause preventable strokes. Guidelines differ regarding AF screening recommendations. We tested whether point-of-care screening with a handheld single lead electrocardiogram (ECG) at primary care practice visits increases diagnoses of AF. Methods: We randomized 16 primary care clinics 1:1 to AF screening using a handheld single-lead ECG (AliveCor KardiaMobile) during vital sign assessments, or usual care. Patients included were aged ≥ 65 years. Screening results were provided to primary care clinicians at the encounter. All confirmatory diagnostic testing and treatment decisions were made by the primary care clinician. New AF diagnoses over one-year follow-up were ascertained electronically and manually adjudicated. Proportions and incidence rates were calculated. Effect heterogeneity was assessed. Results: Of 30,715 patients without prevalent AF (n=15,393 screening [91% screened], n=15,322 control), 1.72% of individuals in the screening group had new AF diagnosed at one year versus 1.59% in the control group (risk difference [RD] 0.13%, 95% confidence interval [CI] -0.16,0.42, P=0.38). New AF diagnoses in the screening and control groups differed by age with the greatest effect observed for those aged ≥ 85 years (5.56% versus 3.76%, respectively, RD 1.80%, 95% CI 0.18,3.30). The difference in newly diagnosed AF between the screening period and the prior year was marginally greater in the screening versus control group (0.32% versus -0.12%, RD 0.43%, 95% CI -0.01,0.84). The proportion of individuals with newly diagnosed AF who were initiated on oral anticoagulants was similar in the screening (n=194, 73.5%) and control (n=172, 70.8%) arms (RD 2.7%, 95% CI -5.5,10.4). Conclusions: Screening for AF using a single-lead ECG at primary care visits was not associated with a significant increase in new AF diagnoses among individuals aged 65 years or older compared to usual care. However, screening may be associated with an increased likelihood of diagnosing AF among individuals aged 85 years or older and warrants further evaluation.

This research attempted to explore the effects of divergent and convergent tasks on the successful reading of EFL students at the preparatory stage. To verify the analysis, the null hypothesis was established that states "There are no differences of statistical significance at the level of (0,05) among the mean of scores of the experimental group who study according to divergent and convergent task technique and the mean of the scores of the control group who study according to the regular method".  The experimental approach is used by designing two equivalent experimental groups of 32 students studying the technique proposed, and an 8-week (2019-2020) control group of 32 students, three classes each week using the Google Classroom Platform and Telegram. The present study utilized the platform Google Classroom (GC) and Telegram as an educational platform to assist students during their course learning process. The writing skills test was administered after checking with the experts. The results show that there are statistical differences at level (0,05) between the average of the experimental and control groups' reading skills and those of the experimental group. This difference is because the experimental group uses divergent and convergent tasks.

INTRODUCTION:In the present study, we investigated the relationship between potency of oxidative stress and BPH and this may assist to contribute to the realistic explanation of the ethiopathogenesis of BPH.METHODS:Seventy four newly diagnosed men with BPH (mean age: 54+/-11.2), who had not undergone any previous treatment for BPH, and 62 healthy volunteers (mean age: 55+/-14) were enrolled in the present study. To determine the antioxidative status of plasma, total antioxidant capacity (TAC) was calculated, and to determine the oxidative status of plasma (TOS) total peroxide levels were measured. The ratio of TAC to total peroxide was accepted as an indicator of oxidative stress (OSI). Data are presented as mean SD +/- unless specified. Student t-test and correlation analyses were used to evaluate the statistical significance differences in the median values recorded for all parameters between BPH and control group.RESULTS:Plasma TAC TOS were found in patients and controls (1.70 +/- 0.32, 1.68 +/- 0.19 micromol Trolox Equiv./L), (12.48 +/- 1.98, 12.40 +/- 1.14 micromol / L) respectively. OSI was calculated as 7.57 +/- 1.91, 7.48 +/- 1.33, respectively. Plasma TAC, TOS and OSI levels were not found to be significantly difference between patients and control subjects (p>0.05, p>0.05, p>0.05).CONCLUSIONS:The present study has shown that there were not relationship between potency of oxidative stress and BPH. Further well designed studies should be planned to find out whether the oxidative stress-related parameters play role in BPH as an interesting pathology in regard of the etiopathogenesis.Keywords: benign prostatic hyperplasia, oxidative stress, prostate

The aim of this study was to investigate the influence of 24-h sleep deprivation on the muscle strength of young, healthy and physically fit people. The research material consisted of physical education students. In total, 67 people participated in the study, including 38 women and 29 men. Respondents were divided into an experimental group “E” of 44 persons subjected to 24-h sleep deprivation and a control group “C” of 23 persons. Students completed the Epworth Sleepiness Scale (ESS) measuring daytime sleepiness. Students performed measurements of the maximum strength of knee joint extensor and flexor muscles. Measurements of muscle strength of flexors and extensors of the knee were taken on a UPR-02 A/S chair with Moment II by Sumer software. ANOVA (analysis of variance) was used to determine the significance of differences between experimental “E” and control “C” group. Statistical significance was defined at the level of p ≤ 0.05. Statistically significant differences were observed in the change of strength levels between groups at the strength moments of right (p < 0.05, η2p = 0.16) and left (p < 0.05, η2p = 0.08) knee muscles extensor. Changes in extensor muscle strength are significant for students with left dominant legs.

Background: Chronic myeloid leukemia (CML) is a myeloproliferative neoplasm. The pathogenesis of CML is based on the oncoprotein termed BCR‐ABL1. TET2 initiates DNA demethylation and is frequently mutated in hematological malignancies including CML.(1) The relation between TET2 acquisition and CML transformation and/or imitinab resistance is needed to be investigated. (2) Aim: To evaluate Ten Eleven Translocation 2 gene (TET2) single nucleotide polymorphism (SNP) (rs2454206, rs34402524, rs61744960) in chronic myeloid leukemia (CML) in relation to the disease prognostic criteria. Materials & Method: The study included 84 subjects; 54 CML in chronic phase and 30 healthy subjects as control group matched for age and sex. Routine investigations including CBC, bone marrow aspiration, biochemical investigations and molecular study were performed in CML patients to identify the disease stage. DNA extraction and SNP assay for TET2 gene polymorphism was done using (Thermo-Fisher predesigned SNP, USA) PCR prism 7500. Results: The mean age was 45.98±15.7 yrs in CML patients and   39.3±6.587 yrs in control group (p>0.05). TET2 SNP rs 34402524 was either heterozygous and homozygous in CML (48%,and 46.2%) but was mainly homozygous among control (80%) group (p=0.012). TET2 SNP rs 2454206 cases within CML (65.4%) and control (63.3%) group had wild patterns (p=0.046). TET2 SNP rs 61744960 showed a homozygous pattern among all groups (CML and control) showing no statistical significance (p=0.528). TET2 SNP in CML cases did not alter the prognostic criteria as no statistical significance was noted (p>0.05) yet, it was significantly related to spleen size in rs 34402524 where homozygous group had huger sizes and higher BCR-ABL1 levels 6 months after starting TKIs (p<0.05). Conclusions/Recommendation: TET2 SNP is a common in Egyptian chronic myeloid leukemia. TET2 SNP rs 3442524 was associated with huger spleen size and higher BCR-ABL1 levels after 6 months of starting TKIs suggesting disease progression.
