Using Appreciative Inquiry to explore the effect of COVID-19 on student trust: medical students' perspective.

This article was migrated. The article was marked as recommended. Background Students' anxiety due to the COVID-19 pandemic was expressed by some medical students in the form of anger and mistrust. This study aims to explore the reasons for mistrust between students and faculty among medical schools in Egypt that have flared during the pandemic. Methodology This is a three-phase exploratory qualitative study depending on thematic emergence from appreciative interviews (AI) sessions. Phase 1 online Appreciative Inquiry (AI) session followed by thematic content analysis. Phase 2 The themes were approached by a smaller cohort of students using a design that relied mostly on the psychometric free association test. Phase 3 The themes were tested on a larger number of students through an online survey. Results Students are revealed to be very well educated regarding contemporary medical education concepts. The most important factors from the student perspective were the presence of a well-designed assessment system aligned with the learning outcomes and teaching methodologies and the presence of extracurricular activities and soft skills, respectively. A balanced student life respecting their mental health was found important to increase trust. Conclusion A roadmap to enhance the student trust must be planned on several pivots: curriculum structure, extracurricular life, communication strategies, and identifying student roles in their learning and decision-making.

Vitamin D deficiency is associated with urinary tract infection in children.

INTRODUCTION: In humans, vitamin D has been shown to play a role in infectious diseases, but its association with acquisition and a complicated course of febrile urinary tract infections (UTIs) has not been investigated. We aimed to investigate the association between 25-hydroxyvitamin D (25(OH)D3) levels and the risk of first time febrile UTI in children. MATERIAL AND METHODS: This prospective case-control study included 50 children with first febrile UTI, with no risk factors for UTI, and 50 age- and sex-matched healthy siblings as controls. White blood cell count, serum C-reactive protein, calcium, phosphorus, alkaline phosphatase and parathormone were measured in all studied children. Vitamin D status was determined by measuring plasma 25(OH)D3 level. Deficiency was defined as a plasma 25(OH)D3 level ≤ 25 nmol/l. RESULTS: Children with UTI had significantly lower mean serum levels of 25(OH)D3 (10.5 ±2.7 nmol/l) than those of controls (25.9 ±5.6 nmol/l) (p < 0.05). Patients with lower UTI had significantly higher serum levels of 25(OH)D3 compared to those with acute pyelonephritis (12.4 ±2.59 vs. 8.2 ±3.2 nmol/l; p < 0.001). Mean serum levels of 25(OH)D3 were significantly lower (p = 0.001) in the female patients compared with males, and this difference was not found within the control group. Multivariate analysis showed that a serum 25(OH)D3 level of ≤ 25 nmol/l is associated with UTI (OR = 1.94, 95% CI: 1.61-2.82; p = 0.04). CONCLUSIONS: Vitamin D deficiency (≤ 25 nmol/l) was an independent risk factor for UTI in children.

Serum cystatin C as an earlier predictor of acute kidney injury than serum creatinine in preterm neonates with respiratory distress syndrome.

In this study, we aimed to evaluate serum cystatin C (sCysC) as an early predictor of acute kidney injury (AKI) in preterm neonates with respiratory distress syndrome (RDS). Sixty preterm neonates diagnosed with RDS and 40 healthy controls (28-36 weeks) admitted to the neonatal Intensive Care Unit were investigated. AKI was defined on the 3rd day of life (DOL-3) as an increase in serum creatinine (sCr) of >0.3 mg/dL from baseline (the lowest previous sCr). sCysC levels were measured on DOL-1, -3 and -7. Of the 60 neonates with RDS, 24 (40%) developed AKI. Five patients (79.17%) were classified as AKI Network (AKIN-1) and 19 patients (20.83%), as AKIN-2. At DOL-3, the mean sCysC values were significantly higher among neonates with RDS and AKI (1.68 ± 0.37) compared with controls (0.79 ± 0.83) and those with RDS and no AKI (0.85 ± 0.20) (P <0.001). sCysC levels significantly increased among neonates with AKI from DOL-3 to DOL-7 (P = 0.002). The sCr values showed no significant difference between those with RDS with AKI, RDS, and no AKI or control groups at DOL-1 and -3. Only as late as DOL-7, the mean values of sCr were higher among neonates with AKI compared with no AKI and controls (P <0.001). The receiver operating characteristic curves area under the curve was 0.97 for predicting the development of AKI within 72 h (P = 0.001). With the best cutoff value of ≥1.28 mg/L, the sensitivity and specificity of sCysC for detecting AKI within 72 h were 100 and 83.3%, respectively. In conclusion, sCysC is an early marker for AKI in neonates with RDS.

Assessment of left atrial mechanical functions and atrial electromechanical delay in Juvenile idiopathic arthritis by tissue Doppler echocardiography.

BACKGROUND: Juvenile idiopathic arthritis (JIA) is a systemic chronic inflammatory disease. Studies using tissue Doppler imaging (TDI) for the evaluation of cardiac functions of children with JIA are limited. Thus, this study was conducted to evaluate Left ventricular function, left atrial mechanical functions and atrial electromechanical delay in JIA. METHODS: This study was carried out as a across sectional study. A total of 34 patients with active JIA and 34 controls were included. Atrial electromechanical delay and left atrial (LA) mechanical functions in addition to systolic and diastolic left ventricular (LV) functions were measured by using conventional echocardiography and TDI. Assessment of disease activity was done using Juvenile arthritis disease activity score (JADAS-27). RESULTS: JIA patients had abnormal atrial electromechanical coupling as established from prolonged lateral mitral annulus (PA lateral), septal mitral annulus (PA septum), inter-atrial and intra-atrial electromechanical delays compared with healthy controls. Left ventricular filling abnormalities were found characterized by a reduced E/A ratio (1.07 ± 0.56 vs. 1.48 ± 0.16, p = 0.01). E/Em was significantly higher in patients with JIA (7.58 ± 1.79 vs. 4.74 ± 1.45, p = 0.003) denoting impaired diastolic function. Left atrial mechanical functions assessment showed significantly decreased LA passive emptying fraction, increased LA active emptying fraction and LA total emptying volume in JIA patients (p = 0.01, p = 0.01, p = 0.03 respectively). CONCLUSION: Atrial electromechanical coupling intervals, and LA mechanical functions were impaired which can be considered as an early form of subclinical cardiac involvement in JIA patients. Significant diastolic functional abnormalities exist in JIA.

Type 1/type 2 cytokine serum levels and role of interleukin-18 in children with steroid-sensitive nephrotic syndrome.

INTRODUCTION: In view of the conflicting evidence of helper T cell type 1 (Th1) or type 2 (Th2) pattern of cytokine synthesis in steroid sensitive nephrotic syndrome (SSNS), this study aimed to assess type-1/type-2 cytokines level in different stages of SSNS and to evaluate the role of IL-18. METHODS: We prospectively studied thirty children with SSNS, aged 2-12 years. The children were evaluated in the active stage before treatment initiation and re-evaluated again during remission while still on steroid treatment. A subgroup of children (21/30) was also evaluated during remission after steroid withdrawal. The control group included 30 healthy age- and sex-matched siblings. Serum levels of IL-2, IFN-γ, ΙL-4, IL-13 and IL-18 were measured by ELISA. RESULTS: IL-2 levels were not significantly different between children in different stages of SSNS and controls (p>0.05). Levels of IL-4, IL-13 and IL-18 were significantly higher during the active stage of SSNS compared to remission and controls (p<0.05). Serum IFN-γ was significantly lower in children with active disease compared to remission stages and controls (p<0.05). In children with SSNS, serum levels of IL-18 correlated significantly with both IL-4 and IL-13 during all stages (r=0.72 and p<0.0001, r=0.82 and p<0.0001, respectively). CONCLUSION: Children with active SSNS seem to have a shift to type-2 cytokine production, and IL-18 expression is significantly correlated with this type-2 immune response.

Glucocorticoid receptors and the pattern of steroid response in idiopathic nephrotic syndrome.

INTRODUCTION: Little is known about the relationships between the T lymphocytes (CD3+) expression of glucocorticoid receptors (GCR) and the response to glucocorticoid treatment in children with idiopathic nephrotic syndrome (NS). The aim of the current study is to determine whether steroid responsiveness is dependent on the amount of T lymphocytes GCR expression. METHODS: We studied 60 children with idiopathic NS in the age group from 2-10 years. According to the response to steroids we classified our patients into early responders (ER; n = 46) and late responders (LR; n = 14). Sixty age and gender matched healthy children represented the control group. The clinical and laboratory findings at baseline and GCR expression by T lymphocytes (CD3+) as determined by flow cytometry were compared between the three groups. RESULTS: The T lymphocytes (CD3+) expression of GCR was significantly lower in the LR than that in the control group (P < 0.01), whereas it was similar in the ER and control groups. GCR expression was also decreased in the LR group compared to the ER group (P < 0.01). Furthermore, the T lymphocytes (CD3+) expression of GCR correlated inversely with the time to complete remission (CR) (r = -0.54, P < 0.05), but not with urinary protein excretion at baseline. CONCLUSION: The levels of T lymphocytes (CD3+) expression of GCR may be a useful predictor of steroid responsiveness in children presenting with idiopathic NS.

Vitamin A status in wheezing Saudi children.

OBJECTIVE: To examine the serum retinol levels of wheezing children, and to investigate the relation as an biochemical indicator of vitamin A status in wheezing children between serum levels of retinol and severity of wheezing. METHODS: A prospective cohort study including 400 wheezing Saudi children aged 3-36 months, who were treated in the pediatrics ward of Ohoud Public Hospital in Al-Madinah, Kingdom of Saudi Arabia between January 2009 and August 2010. Patients were subdivided according to the course of wheeze into 93 patients with persistent wheeze, and 307 patients with acute wheeze. Severity of wheeze was graded mild, moderate, and severe. RESULTS: Among the persistent wheezing patients 9.7% had deficient, and 20.4% had marginal serum vitamin A concentration, while in the acute wheezing patients, 1.6% had deficient, and 8.1% had marginal serum vitamin A concentrations. Results revealed that the prevalence of deficient and marginal vitamin A concentration is higher in the persistent than in the acute wheezing group (p<0.05). Serum vitamin A was related to wheezing severity. Deficient serum vitamin A was found only in severe wheezing groups. CONCLUSION: Wheezing Saudi infants had prevalent deficiency and marginal deficiency of vitamin A. Serum vitamin A concentrations were related to the wheezing severity and course.
