Safety and efficacy of monthly high-dose vitamin D3 supplementation in children and adolescents with sickle cell disease.

Little is known about the impact of vitamin D supplementation on hand grip strength (HGS) and health-related quality of life (HRQoL) in children and adolescents with sickle cell disease (SCD). We aimed to evaluate the safety and efficacy of monthly high-dose vitamin D3 supplementation and its implications on bone mineral density (BMD), HGS, and HRQoL in patients with SCD and healthy controls. The study included 42 children with SCD and 42 healthy matched controls. The study participants were supplemented with high-dose monthly oral vitamin D3. Changes in the serum level of 25(OH) vitamin D3, maximum HGS, and BMD from baseline to 6 months were assessed, and the HRQoL questionnaire and Childhood Health Assessment Questionnaire (CHAQ) were used to evaluate the functional capacity. At baseline, SCD subjects had poorer growth status indicated by negative Z scores. Suboptimal BMD was detected by significantly lower Z score, and lower HGS and worse HRQL parameters were found compared to the controls (P < 0.001). Median 25(OH) vitamin D3 was significantly lower in SCD patients compared to controls (16.5 vs. 28 ng/mL, respectively (P < 0.001)). After 6 months of vitamin D supplementation, there was significant improvement in the DEXA Z-score (P < 0.001), limitation of physical health (P = 0.02), pain scores (P < 0.001), and CHAQ grades (P = 0.01) in SCD patients. A significant improvement in HGS (P < 0.001 and P = 0.005) as well as the CHAQ score (P < 0.001 and P = 0.003) was detected in the SCD group and controls, respectively. There were no reported clinical adverse events (AEs) or new concomitant medications (CMs) during the study duration, and safe levels of Ca and 25 (OH) D3 were observed at 3 and 6 months for both groups. There was a significant positive correlation between HGS and total physical score (r = 0.831, P < 0.001) and a negative correlation with CHAQ score (r = - 0.685, P < 0.001). We also detected a significant positive correlation between vitamin D levels at 6 months and HGS (r = 0.584, P < 0.001), pain score (r = 0.446, P < 0.001), and a negative correlation with CHAQ score (r = - 0.399, P < 0.001).   Conclusion: Monthly oral high-dose vitamin D supplementation was safe and effective in improving vitamin D levels, HGS, and HRQoL in SCD children and healthy subjects, and BMD scores in SCD patients. Further randomized controlled trials are warranted to assess an optimal dosing strategy and to investigate the impact on clinically significant outcomes in children and adolescents with SCD and their healthy counterparts.   Trial registration: ClinicalTrials.gov , identifier NCT06274203, date of registration: 23/02/2024, retrospectively registered. What is known: • Several studies have reported a high prevalence of vitamin D deficiency and suboptimal bone mineral density (BMD) in sickle cell disease (SCD) patients. • Musculoskeletal dysfunction is reported in SCD patients with a negative impact on physical activity and health-related quality of life (HRQL). • Little is known regarding the impact of vitamin D3 supplementation in children and adolescents with SCD. What is new: • We found that monthly oral high-dose vitamin D3 supplementation was safe, tolerated, and effective in improving serum vitamin D levels, HGS, BMD scores, and HRQL in SCD patients.

Attention-deficit hyperactivity disorder in Egyptian medical students and how it relates to their academic performance.

BACKGROUND: The neurobehavioral disorder, known as attention-deficit hyperactivity disorder (ADHD), is characterized by impulsivity, hyperactivity, and a lack of focus. In addition, it is connected to poor academic performance. The purpose of this study was to determine the prevalence of ADHD and its effect on their academic performance among medical students. MATERIALS AND METHODS: This web-based cross-sectional study was conducted among medical students of four medical colleges during December 2021 and April 2022. Data was collected using a self-administered questionnaire comprising Wender Utah Rating Scale and adult ADHD Self-Report Scale [ASRS]. The link to Google Form survey was distributed to students through academic emails and WhatsApp. Data analyzed using SPSS; Chisquare test or Fisher's exact test as appropriate, were used to determine statistical significance. RESULTS: A total of 990 students filled online questionnaire; 54.7% were females.. The estimated prevalence of ADHD in Egyptian medical students was 11%. Students who had childhood ADHD were significantly linked with the present ADHD (r = 0.54, P < 0.001). There was a negative correlation between the ASRS score for ADHD and students' GPA (r = 0.2, P < 0.001). No statistically significant association was observed between ADHD and sex, type of university, and academic level. of the students. CONCLUSION: ADHD is prevalent among medical students. Since most of our students with adult ADHD also had preexisting childhood ADHD, it is crucial that the primary care services, especially school health services, have appropriate standards for the early identification and management of ADHD. Health authorities should conduct a comprehensive health education campaign to raise public awareness of ADHD and its risk factors, the clinical picture, and the burden.

Immunization as an entry point for primary health care and beyond healthcare interventions-process and insights from an integrated approach in Lebanon.

Integrated healthcare systems are continually pitched as major contributors towards better distribution of health outcomes and enhanced well-being. Under emergency conditions, integrated healthcare services can guarantee better access to the target population. In recent years, several crises, i.e., economic collapse, the fuel crisis, the Beirut blast, a large refugee population, and the COVID-19 pandemic, in Lebanon have led to a major shift in the health-seeking behavior of the communities, with preventive services being downprioritized despite being available and curative healthcare services being sought out as late as possible. An extensive drop in immunization coverage and an overstretched public health system presents the risk of Vaccine-Preventable Disease outbreaks and urgent intervention is needed to bridge the immunity gap. The Ministry of Public Health, Lebanon, and UNICEF Lebanon successfully demonstrated the use of an immunization platform as an entry point to reach communities for service delivery, identification and referral, screening, awareness generation, and a host of other services that can be copied for other programs including but not limited to those for Maternal and Child health, nutrition, early childhood development, COVID-19, children with disabilities, social protection, education, health emergencies like cholera, etc., and these can provide bi-directional support to each other. UNICEF along with the MoPH (Ministry of Public Health) has been working towards reaching the most vulnerable population with a bouquet of services through existing immunization touchpoints for favorable healthcare outcomes.

Damage accrual in Behçet disease: Behçet's Syndrome Overall Damage Index (BODI) versus Behçet's Disease Damage Index (BDI).

OBJECTIVES: To assess the validity of Behçet's Syndrome Overall Damage Index (BODI) and Behçet's Disease Damage Index (BDI) as tools for the detection of damage accrual in Behçet's patients compared to Vasculitis Damage Index (VDI). Also, to evaluate the correlation and the interclass correlation among the 3 indices to find out their consistency. METHOD: A prospective cohort study was carried out on 102 adult Behçet's disease (BD) patients who were diagnosed according to the International Study Group criteria for BD. Disease severity and organ damage were assessed for each patient by VDI, BDI and BODI at baseline and 1-year follow-up visits. Damage accrual for each index was defined when there was an increase of at least 1 point (∆ ≥ 1) among the baseline and the follow-up visits. RESULTS: Correlations among the 3 indices were significant, with (r = 0.835, P < 0.001) between VDI and BODI, (r = 0.835, P < 0.001) between VDI and BDI, and (r = 0.844, P < 0.001) between BODI and BDI scores. A highly significant positive correlation existed between the 3 indices and age and disease duration. In contrast, the correlation with the BD Current Activity Form was non-significant, which indicates good discriminative validity of the 3 indices. Neuropsychiatric and ocular systems showed a strong interclass correlation among the 3 indices. Regarding detecting damage accrual, BDI was more sensitive than BODI and showed more agreement with VDI. CONCLUSION: BD damage indices, VDI, BODI and BDI, had good convergent and discriminative validity for the assessment of BD damage. BDI had more sensitivity than BODI to the detection of damage accrual.

Utility of neutrophil/albumin ratio and C-reactive protein/albumin ratio as novel inflammatory markers in Behcet's disease.

INTRODUCTION AND OBJECTIVES: Behcet's disease (BD) is an autoimmune systemic inflammatory disease, and its exact pathogenesis is unknown. There are currently no specific tests to evaluate the disease activity of BD, making its management more difficult. This study aims to determine the neutrophil/albumin ratio (NAR) and C-reactive protein (CRP) to albumin ratio (CAR) and investigate their associations with clinical findings in patients with BD and to determine optimum cutoff levels of CAR and NAR. METHODS: The study included 75 consecutively recruited patients with BD with a mean age of 33.29±6.23 years and disease duration of 7.21±4.64 years, as well as 75 healthy participants. Clinical characteristics and laboratory data were obtained. Disease activity was assessed using the BD current activity form score (BDCAF). RESULTS: NAR and CAR were elevated in patients with BD compared with those of healthy controls (NAR: 1.08±0.34 vs. 0.607±0.06, CAR: 2.49±1.73 vs. 0.39±0.142; p<0.0001), as well as in active BD versus inactive BD. Both NAR and CAR were significantly correlated with CRP, active uveitis, and BDCAF score (p≤0.05). In patients with active BD, the cutoff value of NAR was >0.9744 (sensitivity: 89.74%, specificity: 80.56%), while that of CAR was >2.04 (sensitivity: 74.36%, specificity: 83.33%). CONCLUSIONS: NAR and CAR are both elevated in patients with BD and may contribute to its active state. NAR and CAR can be feasible and inexpensive markers for predicting BD activity.

Introducción y objetivos: La enfermedad de Behçet (EB) es una enfermedad inflamatoria sistémica autoinmune y se desconoce su patogenia exacta. Actualmente no existen pruebas específicas para evaluar la actividad de la EB, lo que dificulta su manejo. El objetivo de este estudio es determinar la proporción neutrófilos/albúmina (NAR) y de proteína C reactiva (CRP)/albúmina (CAR) e investigar sus asociaciones con los hallazgos clínicos en pacientes con EB y determinar los niveles de corte óptimos de CAR y NAR. Métodos: El estudio incluyó a 75 pacientes con EB reclutados consecutivamente con una edad media de 33,29±6,23 años y una duración de la enfermedad de 7,21±4,64 años, así como a 75 participantes sanos. Se obtuvieron características clínicas y datos de laboratorio. La actividad de la enfermedad se evaluó utilizando la puntuación del formulario de actividad actual de la EB (BD Current Activity Form [BDCAF]). Resultados: NAR y CAR estaban elevados en pacientes con EB en comparación con controles sanos (NAR: 1,08±0,34 vs. 0,607±0,06, CAR: 2,49±1,73 vs. 0,39±0,142; p<0,0001), así como en pacientes EB activos versus EB inactivos. Tanto la NAR como la CAR se correlacionaron significativamente con la PCR, la uveítis activa y la puntuación BDCAF (p≤0,05). En pacientes con EB activa, el valor de corte de NAR fue>0,9744 (sensibilidad: 89,74%, especificidad: 80,56%), mientras que el de CAR fue>2,04 (sensibilidad: 74,36%, especificidad: 83,33%). Conclusiones: NAR y CAR están elevados en pacientes con EB y pueden contribuir a su estado activo. NAR y CAR pueden ser marcadores factibles y económicos para predecir la actividad de EB.(AU)

Antibodies against a mutated citrullinated vimentin in patients with rheumatoid arthritis.

Rheumatoid arthritis (RA) is an autoimmune disease characterized by autoantibodies against citrullinated antigens. The anti-cyclic citrullinated peptide (Anti-CCP) test is commonly used to diagnose rheumatoid arthritis, whereas the anti-mutated citrullinated vimentin (Anti-MCV) is another anti-citrullinated antibody that reacts with mutated citrullinated vimentin. Therefore, we aimed to assess the diagnostic value of anti-MCV antibodies in RA patients and their relation to disease activity. This study included 60 RA patients and 25 normal controls. The disease activity of RA patients was assessed by disease activity score (DAS-28). ELISA was used to test patients and controls for anti-MCV and anti-CCP. The level of anti-MCV was significantly higher among patients with RA compared to the control group (1.56 ± 0.56 vs. 1.20 ± 0.19 mol/l; P< 0.001). Anti-MCV at cut-off point of > 1.2 mol/l had 76% sensitivity and 100% specificity, with an overall diagnostic accuracy of 83.2% for diagnosing RA. Regarding early RA diagnosis, anti-MCV at the cut-off point was > 1.2 mol/l with 70% sensitivity and 100% specificity. For diagnosis of late RA, the cut-off point was > 1.2 mol/l, with 93.3% sensitivity and 100% specificity, whereas the overall diagnostic accuracy was 96.3%. In this study, patients with positive anti-CCP had a marginally higher level of anti-MCV compared to those with negative anti-CCP (1.64 ± 0.28 vs. 1.48 ± 0.73 mol/l; P= 0.29). We concluded that serum levels of Anti-MCV can be used as a diagnostic test in RA. The increased serum levels of Anti-MCV, demonstrated the importance of Anti-MCV as an independent serum marker in predicting the outcome of RA.

Validity and reliability of the Arabic version of the Self-Efficacy for Managing Chronic Disease scale in rheumatoid arthritis patients.

BACKGROUND AND OBJECTIVES: Rheumatoid arthritis (RA) is an autoimmune inflammatory condition that causing disability and affection of patient's quality of life (QoL). Self-efficacy investigation helps us to detect the requirements of chronically affected patients and evaluation of self-care management programs. The aim of our study was to test validity and reliability of Self-Efficacy for Managing Chronic Disease (SEMCD-Arabic) in RA patients. METHOD: This study included 248 RA patients, carried out at Rheumatology and Rehabilitation Department. The SEMCD-Arabic Validity was assessed by correlating the SEMCD-Arabic scale with the validated Arabic version of the modified Health Assessment Questionnaire HAQ (MHAQ), the Arabic version of the Multidimensional Assessment of Fatigue (MAF) scale, and the Arabic version of Short Form 36 version 2 for quality of life (SF QoL). Internal consistency, test-retest reliability was assessed. RESULTS: Convergent validity was confirmed by a positive correlation between (physical, mental) component of SF QoL and SEMCD-Arabic (r = 0.918, r = 0.925) respectively, and negative correlation between MAF and SEMCD-Arabic (r = - 0.657) and MHAQ with SEMCD-Arabic (r = - 0.595). Discriminant validity confirmed by a significant negative correlation between visual analogue scale (VAS) for pain, disease activity scale (DAS28), Morning stiffness, patient health, physician health, age, duration, and SEMCD-Arabic (r = - 0.1-0.7) (P < 0.001). Test-retest reliability was estimated which revealed a high interclass correlation coefficient (ICC = 0.87-0.997) indicating excellent agreement and internal consistency is acceptable as the Cronbach's alpha value (0.660 to 0.78). CONCLUSION: The SEMCD-Arabic questionnaire can be used as a valid and reliable measure for assessment of patient's self-efficacy in RA. Key Points • The SEMCD-Arabic questionnaire has a statistically significant validity in correlation with different clinical manifestations MHAQ, SF QoL, and MAF. • The Arabic SEMCD is highly reliable with a Cronbach's alpha of 0.660 to 0.78.

Effects of tDCS on Language Recovery in Post-Stroke Aphasia: A Pilot Study Investigating Clinical Parameters and White Matter Change with Diffusion Imaging.

Objectives: In this pilot study we investigated the effects of transcranial direct current stimulation (tDCS) on language recovery in the subacute stage of post-stroke aphasia using clinical parameters and diffusion imaging with constrained spherical deconvolution-based tractography. Methods: The study included 21 patients with subacute post-stroke aphasia. Patients were randomly classified into two groups with a ratio of 2:1 to receive real tDCS or sham tDCS as placebo control. Patients received 10 sessions (5/week) bi-hemispheric tDCS treatments over the left affected Broca's area (anodal electrode) and over the right unaffected Broca's area (cathodal stimulation). Aphasia score was assessed clinically using the language section of the Hemispheric Stroke Scale (HSS) before and after treatment sessions. Diffusion imaging and tractography were performed for seven patients of the real group, both before and after the 10th session. Dissection of language-related white matter tracts was achieved, and diffusion measures were extracted. A paired Student's t-test was used to compare the clinical recovery and diffusion measures of the dissected tracts both pre- and post- treatment. The partial correlation between changes in diffusion measures and the language improvements was calculated. Results: At baseline assessment, there were no significant differences between groups in demographic and clinical HSS language score. No significant clinical recovery in HSS was evident in the sham group. However, significant improvements in the different components of HSS were only observed in patients receiving real tDCS. Associated significant increase in the fractional anisotropy of the right uncinate fasciculus and a significant reduction in the mean diffusivity of the right frontal aslant tract were reported. A significant positive correlation was found between the changes in the right uncinate fasciculus and fluency improvement. Conclusions: Aphasia recovery after bi-hemispheric transcranial direct current stimulation was associated with contralesional right-sided white matter changes at the subacute stage. These changes probably reflect neuroplasticity that could contribute to the recovery. Both the right uncinate fasciculus and right frontal aslant tract seem to be involved in aphasia recovery.

Wet Specimens, Plastinated Specimens, or Plastic Models in Learning Anatomy: Perception of Undergraduate Medical Students.

BACKGROUND: Methods of teaching anatomy have shown major change as the medical undergraduate curriculum became more challenging. Traditional teaching methods like dissection and wet specimens are nowadays widely replaced by anatomical models, plastination, and technology-enhanced applications. AIM: To explore the perception of undergraduate students of three methods of learning anatomy, which are wet specimens, plastinated specimens, and plastic models. METHODS: This is a descriptive, cross-sectional, questionnaire-based study that included a sample of 268 male and female undergraduate medical students of the third and fourth study years at Ibn Sina National College for Medical Studies in Saudi Arabia. RESULTS: Students in this study preferred wet specimens in regard to motivation to gaining anatomical knowledge in clinical context and usefulness for surgical career. On the other hand, they preferred plastinated specimens when it comes to feasibility of use, ability to differentiate between structures, and understanding complex structures. CONCLUSION: Although the findings in general refer to preferring the use of wet specimens, no one modality seems to be enough for effectively learning anatomy. A combination of various modalities can provide the best benefit for medical students in this regard.

Influence of Personality Traits and Learning Styles on Undergraduate Medical Students' Academic Achievement.

PURPOSE: Learning focus has shifted from conventional teacher-centered to student-centered; therefore, methods used to support and encourage learners must be considered. Meanwhile, the individual differences between learners should be taken into consideration by medical educators. Aiming to achieve a better learning experience, the current study investigates the relationship between personality traits and learning styles and their effect on students' academic achievement. SUBJECTS AND METHODS: An analytical, cross-sectional study, encompassing a sample of 333 undergraduate first-year medical students, at the Faculty of Medicine, Suez Canal University in Egypt was conducted. The Big Five personality traits test and VARK learning styles questionnaires were used to assess students' personality traits and learning styles, respectively, in the medical education module which is a part of the Foundation II module. The former is five weeks' duration and is followed by a summative exam at the end. Students' academic achievement was determined from their grades in Foundation II module by the end of the semester. RESULTS: Study findings generally indicate that the highest domain of learning styles among students is the kinesthetic domain. A statistically significant difference between males and females regarding their learning style preferences was detected. Also, there was a statistically significant relationship between auditory and kinesthetic learning styles and academic achievement. Though there was a significant relationship between kinesthetic learning style with both openness traits and academic achievement, no significant statistical relationship was found between any of the personality traits and academic achievement. CONCLUSION: This study concludes that learning style could affect students' academic achievement. It reveals that the kinesthetic learning style is the most preferred learning style among our medical students, also the agreeableness and openness traits were the most common personality traits among them. No significant relationship was detected between personality traits and academic achievement.

A guide for evaluation of online learning in medical education: a qualitative reflective analysis.

BACKGROUND: With the strike of Covid-19, an unprecedented rapid shift to remote learning happened worldwide with a paradigm shift to online learning from an institutional adjuvant luxury package and learner choice into a forced solo choice. This raises the question of quality assurance. While some groups have already established standards for online courses, teaching and programs yet very little information is included on methodology of their development and very little emphasis is placed on the online learning experience. Nevertheless, no work has been done specifically for medical education institutions. AIM: To develop a set of descriptors for best practice in online learning in medical education utilizing existing expertise and needs. METHODS: This work utilizes a qualitative multistage approach to identify the descriptors of best practice in online learning starting with a question guided focus group, thematic analysis, Delphi technique and an expert consensus session done simultaneously for triangulation. This was done involving 32 institution in 19 countries. RESULTS: This materialized into the development of a set of standards, indicators, and development of a checklist for each standard area. The standard areas identified were organizational capacity, educational effectiveness, and human resources each of which listed a number of standards. Expert consensus sessions identified the need for qualification of data and thus the development of indicators for best practice. CONCLUSION: Standards are needed for online learning experience and their development and redesign is situational and needs to be enhanced methodologically in axes that are pertaining to the needs of the education community. Taking such axes into consideration by educators and institutions will lead to planning and implementing successful online learning activities, while taking them into consideration by the evaluators will help them conduct comprehensive audits and provide stakeholders with highly informative evaluation reports.

Is There a Feasible Link between Vitamin D Receptor Genotypic and Allelic Frequencies with Analytical Biomarkers of Rheumatoid Arthritis Disease?

Rheumatoid arthritis (RA) is one of the most widespread autoimmune disorders and it has a genetic background with a variety of genes affecting the degradation of the immune system. Along these lines, we assessed the relationship between the BsmI, and FokI VDR polymorphisms and inflammable records identified with infections activity. Such as interleukins (IL-6, IL-8), hypoxia inducible factor-alpha (HIF-α), soluble receptor of advanced glycation end product (sRAGE), oxidized low-density lipoprotein cholesterol (oxLDL), neutrophil gelatinase-associated lipocalin (NGAL) and procollagen N-propeptide of type III collagen (P3NP) and the allelic frequencies of BsmI VDR rs1544410 and FokI VDR rs2228570 polymorphism on the RA. Total of 131 subjects [70 RA patients and 61 age and sex matched apparently healthy controls (HC)] were monitored for inflammatory biomarkers using ELISA. All patients were screened for the BsmI and FokI using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The all biomarkers were significantly higher in RA patients in comparison with HC. There were positive correlations between NGAL, oxLDL and s-RAGE, oxLDL. On BsmI, 'GG' and 'AG' genotypes were significantly associated with high RA activity as well as the frequency of genotypes 'AG & GG" were higher in high activity RA as compared to low RA activity. However on FokI, was observed that in high activity patients the frequency of 'CC' & 'CT' was more prevalent as compared to low activity ones. These outcomes support the immunoregulatory role of vitamin D which is associated with several inflammatory diseases, signifying a credible anti-inflammatory role in perturbation of the RA.
