Objective. To evaluate vitamin D deficiency and body composition of women submitted to bariatric surgery and relate their body mass index variation after surgery to 25(OH)D concentrations. Method. A cross-sectional and controlled study was performed including 49 obese adult volunteer women, submitted to Roux-en-Y gastric bypass (RYGB group). Collected Data. Body mass index (BMI), self-declared ethnicity, economic condition, physical activity level, serum concentrations of 25-hydroxycholecalciferol (25(OH)D; radioimmunoassay), parathormone, and body composition by dual-energy X-ray absorptiometry (Hologic DXA-QDR-1000) were collected. Results. 25(OH)D deficiency was found in 27 (55.1%) and 8 (21.1%) in the RYGB and control groups (p=0.002). Secondary hyperparathyroidism was more frequent in the RYGB group compared to the control group (15 (30.6%) versus 1 (2.6%); p=0.001). There was no relation of the studied variables and body composition with 25(OH)D deficiency. 25(OH)D concentrations were correlated (r=−0.531; p<0.001) with BMI reduction, regardless of vitamin D supplementation. Conclusion. Women submitted to bariatric surgery (RYGB) around three years ago had higher BMI and vitamin D deficiency, along with hyperparathyroidism, compared to the control group. There was no association between variables related to body composition and 25(OH)D concentrations. On the other hand, vitamin concentrations correlated negatively to BMI variation after undergoing surgery.

Significant Difference

Introduction: Body weight gain in children and teenagers is one of the major challenges that cause undesirable health outcomes. Simultaneously with the prevalence of overweight and obesity, children and adolescents are diagnosed with 25-hydroxyvitamin D (25(OH)D) deficiency in different sides of the world. The present study aimed to assess 25(OH)D status among Iranian volunteers aged 1-16 years and find the correlation between 25(OH)D status and body mass index (BMI) subjects.    Material and Methods: The total volunteers included 807 Iranian children aged 1 to 16 referred to the general and endocrinology clinics in Babol city, Mazandaran Province. A trained physician determined anthropometric characteristics. Serum levels of calcium (Ca), phosphate (P), creatinine (Cr), urea, thyroxine (T4), thyroid-stimulating hormone (TSH), and 25(OH)D were assessed in all children.      Results: 25.27% of the children were 25(OH)D deficient, and 59.1% were insufficient. There was no significant difference in serum 25(OH)D level between girls and boys (P=0.13). A significant negative correlation was found in serum 25(OH)D level with weight (P=0.000, r=-0.12), BMI (P=0.000, r=-0.13), and age (P=0.000, r=-0.13). Conclusion: These data displayed that 25(OH)D insufficiency is highly prevalent among children in the north of Iran. Serum 25(OH)D levels are affected by age and BMI value. Improving vitamin D deficiency helps to maintain the health of children and adolescents during this critical period.

Introducción: La etapa universitaria es un proceso determinante para consolidar los hábitos de vida, donde los estudiantes se ven obligados a cambiar la mayoría de sus hábitos, que propician una mala alimentación, pobre organización del tiempo y menor actividad física, teniendo repercusiones en la condición y estructura física, lo que puede afectar considerablemente el estado de salud de esta población. Objetivo: El objetivo de este trabajo fue determinar las diferencias en la composición corporal y actividad física en estudiantes universitarios según su año de ingreso. Materiales y métodos: Participaron en el estudio 287 estudiantes de ambos sexos (171 mujeres y 116 hombres), pertenecientes a las facultades de “Filosofía y Educación”, “Ingenierías” y “Ciencias”, a los cuales se les realizó una evaluación antropométrica para estimar la composición corporal con las ecuaciones de De Rose y Guimaraes y un cuestionario de frecuencia de actividad física. Resultados: Los resultados indican que existen diferencias en el Índice de Masa Corporal y masa grasa entre estudiantes mujeres de 1º y 2º año y entre 1º y 5º año en los hombres. La masa muscular no presenta grandes diferencias entre los grupos, pero si se aprecia cambios negativos entre el Índice de Masa Corporal y masa grasa de estudiantes que recién ingresan versus los estudiantes de último año. Conclusiones: Durante la universidad se vive un periodo crítico que afecta el nivel actividad física y el estado nutricional de los estudiantes y que podría empeorar en estudiantes con más años en la universidad.AbstractIntroduction: The university stage is a determining process when consolidating people’s habits of life, where students are forced to change most of their habits favoring a poor diet, poor organization of time and less physical activity, which at the same time, has an impact on the condition and physical structure and can significantly affect the health status of this population. Objective: To determine the differences in body composition and physical activity in university students according to their year of admission. Materials and methods: The study involved 287 male and female students (171 women and 116 men) who belonged to the faculties of Philosophy and Education, Engineering and Science, who underwent an anthropometric assessment to estimate body composition with De Rose and Guimaraes equations and a frequency of physical activity questionnaire. Results: The results show that there are differences in Body Mass Index and fat mass among female students of first and second year and between the first and fifth year in men. Muscle mass had no significant differences between groups, but there is negative changes between Body Mass Index and fat mass from students newly admitted versus students in their last year. Conclusions: During the university stage, students face a critical period that affects their physical activity level and nutritional status, which could get worse for students with more years at the university.

Vitamin D Levels

INTRODUCTION: Obesity is associated with alteration in the vitamin D levels and has been related to vitamin D status. Lower vitamin D levels in higher BMI individuals may be secondary to an alteration in tissue distribution resulting from an increase in adipose mass. Therefore women with higher BMI need higher vitamin D supplementation as compared to women with BMI within normal range.  MATERIAL AND METHOD: This was a case control study carried out in Department of Obstetrics and Gynaecology, ESIC-PGIMSR, New Delhi from August 2012-April 2014. A total of 100 patients were divided into two equal groups (control and study groups of 50 each). Control group had women with singleton uncomplicated term normotensive pregnant women in labour while the study group comprised of term preeclamptic women in labour.In all the patients their BMI was analysed .Blood samples for vitamin D, serum calcium, serum phosphorus, serum parathormone, serum alkaline phosphatase levels were drawn and subsequently their levels were evaluated in cord blood; correlation studied between vitamin D & BMI. RESULTS: The mean BMI was relatively higher in the study group (26.34 ± 4.12)kg/m2 than in the control group ( 24.24 ± 3.13)kg/m2. Thus in our study a prevalence of higher BMI was seen in patients of preeclampsia. When all the 100 women are being considered, median vitamin D levels were found to be higher (6.6ng/ml) in normal BMI patients (n=55) as compared to levels (5.6ng/ml) in patients with higher BMI(n=45).  CONCLUSION: Vitamin D levels are related to maternal body mass index. Individuals with higher percentage body fat may require higher vitamin D intake to attain optimal 25(OH) D levels, compared with lean individuals and thereby may prevent pregnancy complications like Pre eclampsia.

Study Design: Prospective/Observational Place and Duration: Departments of Medicine & Pulmonology, Allama Iqbal Memorial Teaching Hospital, Sialkot and Department of Medicine, Sughra Shafi Medical Complex Narowal from 1st November 2020 to 30th April 2020. Methodology: One hundred and sixty patients of both genders diagnosed to have COVID-19, were enrolled. Patient’s ages were ranging from 17 to 70 years. The detailed demographics such as age, sex, and body mass index were recorded. 5 ml blood samples were taken from all the patients to check their vitamin D levels. Severe Vitamin D deficiency was defined as 25(OH)D <25 nmol/L (10 ng/dl). Association between mortality and morbidity was examined. Results: Ninety (56.25%) were males while 70 (43.75%) were females with mean age 40.15±17.37 years. Mean body mass index of patients was 24.16±7.26 kg/m2. Severe vitamin D deficiency was observed in 80 (50%) patients. Mortality found in 30 (18.75%) patients. Frequency of morbidity was among 66 (41.25%) patients. Patients with severe vitamin D deficiency had high rate of mortality 20 (25%) and morbidity 50 (62.5%) as compared to patients with no vitamin D deficiency had 10 (8%) mortality and 16 (20%) morbidity. A significant association was observed between severe vitamin D deficiency regarding morbidity and mortality among patients with covid-19 disease with p-value <0.05. Conclusion: The vitamin-D has strongest relationship among patients with covid-19 disease to reduce mortality and morbidity. Keywords: Morbidity, COVID-19, Vitamin D, Mortality

Vitamin D (VitD) has a critical role in phosphorous–calcium metabolism as well as an important role in the immune system. In the human body, VitD is synthesized as cholecalciferol in the skin, but this process requires sunlight (UVB) radiation. Numerous reports showed high prevalence of VitD deficiency, particularly during the winter season, indicating the importance of VitD supplementation. Various factors can affect the absorption of VitD, including dosage and formulation. The primary study objective was to examine the efficiency of supplementation with three different formulations containing cholecalciferol in comparison with the control group. The secondary objective was to identify other factors affecting increase in serum 25-OH-VitD. A randomized controlled intervention study was conducted in Slovenia during wintertime (January– March) on 105 apparently healthy subjects (aged 18–65 years) with suboptimal VitD status (25-OH-VitD 30–50 nmol/L). Subjects were randomized into four groups: three treatment groups receiving (A) capsules with starch-adsorbed VitD, (B) oil-based Valens VitD oral spray, or (C) water-based Valens VitD oral spray and a control group (D) which did not receive supplemental VitD. Two months of supplementation with cholecalciferol (1000 IU; 25 µg daily) resulted in significant increase in serum 25-OH-VitD levels in comparison with control group (pooled Δc 32.8 nmol/L; 95% CI: 23.0, 42.5, p < 0.0001). While we did not observe any significant differences between the tested formulations, the efficiency of supplementation was associated with body mass index and baseline serum 25-OH-VitD level. Higher supplementation efficiency was observed in participants with normal body weight (BMI < 25) and in those with more pronounced VitD insufficiency. We also determined that tested dosage was not sufficient to achieve recommended 25-OH-VitD levels in all subjects.
