Abstract
Objective To explore the changes of serum-related indexes at different time points, so as to identify the critical time of converting from simple premature thelarche (PT) to idiopathic central precocious puberty (ICPP). Methods This is a retrospective study. The subjects of the study were 50 girls with PT who were admitted to the Children's Hospital of Hebei Province from January 2019 to September 2020. The enrolled 50 children were divided into the conversion group(n=12) and the non-conversion group(n=38) according to whether PT was converted into ICPP during follow-up. Furthermore, the levels of serum-related indexes and uterine and ovarian volumes were compared after the diagnosis of PT. Results The IGF-1 and IGFBP-3 levels of children in the conversion group began to change significantly from six months after the diagnosis, with statistically significant differences when compared with the levels of children at the initial diagnosis, three months and those of the non-conversion group at the same time points (p<0.05). The levels of vitamin-D, DHEA and leptin began to change significantly at nine months after the diagnosis (p<0.05). Besides, uterine and ovarian volumes in the conversion group began to increase significantly six months after the diagnosis, with statistically significant differences when compared with those in the non-conversion group (p<0.05). Conclusion Findings in our study suggest that regular monitoring of vitamin-D, IGF-1, IGFBP-3, DHEA and leptin levels, and uterine and ovarian volumes can predict the conversion from PT to ICPP at an early stage.

Abstract
Objective Genetic polymorphisms in genes involved in growth process and Vitamin-D metabolism form a significant etiology behind growth hormone deficiency and short stature. The aim of this study was to explore for known and unknown genes and variants related to growth hormone and short stature in a family based study using whole exome sequencing (WES). Method This family-based study included a family with members diagnosed with growth hormone deficiency, short stature and Vitamin-D deficiency (four boys affected and four boys non-affected). The participants were recruited from King Abdulaziz University Hospital (Jeddah, Saudi Arabia) and referred to King Fahad Centre for Medical Research (Jeddah, Saudi Arabia from April 2022 to June 2022. The consanguineous parents and one of the affected boys (aged 16 years old) underwent WES. Results Several variants in RNPC3, ACAN, GC, VDR and LRP2 were identified in index cases but not in controls. Novel frameshift and splice region variants in RNPC3 (c.358dupA, p.Arg120fs) were detected. Other missense variants were also observed including variants in ACAN (c.2591C>T, c.2789G>T, c.2815T>A, c.4207A>G, c.4523A>C and c.7119C>G), GC (rs4588 and rs7041) and LRP2 (rs2075252 and rs1991517). A start loss variant in VDR (rs2228570) with high impact was also observed. Conclusions Our findings suggest a potential association of these variants with growth hormone deficiency and short stature. In this study, novel pathogenic variants in RNPC3 were revealed as well as other variants in ACAN and in genes related to Vitamin-D metabolism (GC, VDR and LRP2) that some or all might be associated with growth hormone deficiency. Further large-scale studies are required to address the association of these variants with growth hormone deficiency and its subsequent short stature.

Abstract
Acute lung injury is a life-threatening medical problem induced by sepsis or endotoxins and may be associated with enhanced Endoplasmic reticulum stress (ER stress). Vitamin-D (Vit-D) possesses an anti-inflammatory effect; however, this specific mechanism on acute lung injury is still unknown. Here we scrutinize the mechanism of Vit-D on Acute lung injury (ALI) models and explored the Vit-D augmented miRNA's role in regulating the ER stress pathway in ALI. Sepsis was induced by CLP, and Endotoxemia was caused by lipopolysaccharide (LPS). We found that Vit-D alleviates pulmonary edema, improves lung histoarchitecture, infiltration of neutrophils, endothelial barrier in mice, and improves ER stress markers Activating Transcription Factor 6 (ATF6) and CHOP (C/EBP Homologous Protein) expression elevated by CLP/LPS induce ALI. Vit-D decreases the nitric oxide production and ATF6 in macrophages induced by LPS. Vit-D augments miR (miR-149-5p) in LPS-induce macrophages, CLP, and LPS-induced ALI models. Vit-D enhanced miRNA-149-5p when overexpressed, inhibited ER-specific ATF6 inflammatory pathway in LPS-stimulated macrophages, and improved histoarchitecture of the lung in LPS/CLP-induced mice models. This vitro and vivo studies demonstrate that Vit-D could improve ALI induced by CLP/LPS. In this regard, miR-149-5p may play a crucial role in vitamin-D inhibiting LPS/CLP induce ALI. The mechanism might be an association of increased miR-149-5p and its regulated gene target ATF6, and downstream CHOP proteins were suppressed. Thus, these findings demonstrate that the anti-inflammatory effect of Vit-D is achieved by augmentation of miRNA-149-5p expression, which may be a key physiologic mediator in the prevention and treatment of ALI.

Abstract
Introduction Heart Failure is a leading cause of mortality worldwide including India. Most cross sectional studies have demonstrated heart failure is associated with deficiency of essential micronutrients including Vitamin D which may play a important role in pathogenesis of ventricular remodelling in heart failure. Aim Our study performed aimed to determine the effect of supplementation in patients of Heart Failure presenting with Vitamin D deficiency to our institute on severity of Heart Failure. Design and Method 97 patients of Heart failure coming to our institute were given conventional therapies for Heart Failure along with Vitamin supplementation based on serum Vitamin D levels and followed up for 3 months. Results Patient of Heart failure having Vitamin D deficiency had significant reduction in cardiac biomarkers (NT-pro BNP levels), improvement in Left ventricular ejection fraction (LVEF) and more favourable reverse remodelling determined by Left ventricular end diastolic and systolic diameter (LVEDD & LVESD) though quality of life determined by WHODAS 2.0 score did not changed following 12 weeks supplementation of High Dose Vitamin D. Conclusion Recognising and treatment of Vitamin D deficiency may determine long term prognosis in patients of Heart Failure.

Abstract
Novel coronavirus 2019 (COVID-19) is a zoonosis that revised the global economic and societal progress since early 2020. The SARS-CoV-2 has been recognized as the responsible pathogen for COVID-19 with high infection and mortality rate potential. It has spread in 192 countries and infected about 1.5% of the world population, and still, a proper therapeutic approach is not unveiled. COVID-19 indication starts with fever to shortness of breathing, leading to ICU admission with the ventilation support in severe conditions. Besides the symptomatic mainstay clinical therapeutic approach, only Remdesivir has been approved by the FDA. Several pharmaceutical companies claimed different vaccines with exceptionally high efficacy (90–95%) against COVID-19; how long these vaccines can protect and long-term safety with the new variants are unpredictable. After the worldwide spread of the COVID-19 pandemic, numerous clinical trials with different phases are being performed to find the most appropriate solution to this condition. Some of these trials with old FDA-approved drugs showed promising results. In this review, we have precisely compiled the efforts to curb the disease and discussed the clinical findings of Ivermectin, Doxycycline, Vitamin-D, Vitamin-C, Zinc, and cannabidiol and their combinations. Additionally, the correlation of these molecules on the prophylactic and diseased ministration against COVID-19 has been explored.

Abstract
BACKGROUND Vitamin-D is an immune-modulator which might be linked to disease severity by SARS-CoV-2. METHODS Meta-analysis of RCTs and quasi-experimental studies, evaluating the role of vitamin-D supplementation in COVID patients was done. RESULTS Total 5 studies (3 RCTs and 2 Quasi-experimental) including n = 467 patients were included. Vitamin D didn't reduce mortality (RR 0.55, 95%CI 0.22 to 1.39, p = 0.21), ICU admission rates (RR 0.20, 95% CI 0.01-4.26, p = 0.3) and need for invasive ventilation (RR 0.24, 95% CI 0.01-7.89, p = 0.42). CONCLUSION No significant difference with vitamin-D supplementation on major health related outcomes in COVID-19. Well-designed RCTs are required addressing this topic.

Abstract
Since the birth of Christ, in these 2019 years, the man on earth has never experienced a survival challenge from any acellular protist compared to SARS-CoV-2. No specific drugs yet been approved. The host immunity is the only alternative to prevent and or reduce the infection and mortality rate as well. Here, a novel mechanism of melanin mediated host immunity is proposed having potent biotechnological prospects in health care management of COVID-19. Vitamin D is known to enhance the rate of melanin synthesis; and this may concurrently regulate the expression of furin expression. In silico analyses have revealed that the intermediates of melanin are capable of binding strongly with the active site of furin protease. On the other hand, furin expression is negatively regulated via 1-α-hydroxylase (CYP27B1), that belongs to vitamin-D pathway and controls cellular calcium levels. Here, we have envisaged the availability of biological melanin and elucidated the bio-medical potential. Thus, we propose a possible synergistic application of melanin and the enzyme CYP27B1 (regulates vitamin D biosynthesis) as a novel strategy to prevent viral entry through the inactivation of furin protease and aid in boosting our immunity at the cellular and humoral levels.

Abstract
The purpose of the current systematic review was to identify the prevalence of hypovitaminosis-D in LE-TJA patients; and outline the association between pre-operative hypovitaminosis and post-operative outcomes. A search of PubMed-Medline and the Cochrane-Library databases was performed for literature published before November 27th, 2019. The eighteen studies analyzed had a pooled prevalence for vitamin D insufficiency (20 - <30 ng/mL) and deficiency (<20 ng/mL) of 53.4% and 39.4%, respectively. Hypovitaminosis-D was associated with higher complication rates (p = 0.043), and a greater prevalence among septic versus aseptic revisions (p = 0.016). Therefore, pre-operative screening for hypovitaminosis-D can be beneficial in patients undergoing LE-TJA. LEVEL OF EVIDENCE Systematic Review (Level III).

Abstract
OBJECTIVE Hashimoto's thyroiditis (HT) is a variant of autoimmune thyroid disorders (AITD) which has been associated with vitamin D (vit-D) deficiency. However, whether vit-D supplementation is linked to reduction of thyroid autoantibodies and improvement of thyroid function is not well characterized. The present study was planned to evaluate the effect of vit-D supplementation on possible improvement of thyroid autoantibody titer and thyroid hormone profile in patients with AITD subjects. METHODS Twenty-three patients of HT were given weekly supplementation of 60,000 IU vit-D for 8 weeks followed by once a month for another 4 months. After 6 months of vit-D supplementation, thyroid autoantibody titer (TPO antibody) and thyroid hormone profile was rechecked. RESULTS Mean serum vit-D was increased significantly from 15.33 ± 5.71 to 41.22 ± 12.24 ng/mL (normal levels) after supplementation. There was significant increase in thyroid autoantibody titre (from 746.8 ± 332.2 to 954.1 ±4 59.8 IU/ml; P = 0.006) and TSH level (7.23 ± 3.16 to 3.04 ± 2.62 (mIU/L); P = 0.01) following 6 months of vit-D supplementation. CONCLUSION Vitamin-D levels were low in AITD patients in eastern India and, its supplementation in HT patients increased thyroid antibody titer and there was significant reduction in serum TSH and increased in free T4.

Abstract
OBJECTIVES The main purpose of the current study was to investigate nasal mucociliary clearance time (NMC) in patients with Vitamin-D deficiency. METHODS A total of 55 patients with Vitamin-D deficiency and 32 controls were evaluated. NMC time was measured with subjective saccharine test and compared between study and control groups. In addition, NMC time was re-evaluated after Vitamin-D replacement protocol in patients with Vitamin-D deficiency. RESULTS The mean 25(HO)Vitamin-D levels were 14.32 ± 4.23 ng/mL (7-24.6) and 29.38 ± 7.05 ng/mL (25-53.8) in study and control groups, respectively (p < 0.001). The mean NMC time was 11.15 ± 3.05 (6.3-17.6) and 8.40 ± 2.33 (6-13.2) in study and control groups, respectively (p < 0.001). The mean 25(HO)Vitamin-D level after the replacement protocol was 33.38 ± 10.03 and the mean NMC time was 9.56 ± 2.54 (p < 0.001). CONCLUSION The mean NMC time was significantly increased in patients with Vitamin-D deficiency which can be corrected after Vitamin-D replacement protocols. The prolonged mucociliary clearance might be one of the pathophysiologic pathways at increased upper respiratory tract infections, and sinonasal and ear infections in patients with Vitamin-D deficiency.

Abstract
This study aims to determine Vitamin-D level in patients with primary dysmenorrhea and investigate the effect of Vitamin-D replacement on symptoms. About 100 patients in the 18-30 age group followed-up with primary dysmenorrhea diagnosis were included in this observational study. The pain severity was assessed using the visual analog scale (VAS). 25-hydroxy vitamin D(25(OH)D) levels of the patients were measured and the replacement therapy was applied according to measurement results. The patients were followed for three months in total. At the end of the three-month period, the 25(OH)D level was measured and the VAS score was assessed once more after the therapy. 25(OH)D level was insufficient in 23.0%, deficient in 45.0%, and severely deficient in 32.0% of the patients. It was found that the VAS score increased as the 25(OH)D level decreased (r = -0.320; p = .002). A significant reduction was observed in VAS scores after Vitamin-D treatment in all three groups; the amount of reduction in VAS score was determined to be higher in the patients with severely deficient levels of 25(OH)D, compared to the patients with deficient or insufficient levels (p < .001). A significant and negative correlation was found between Vitamin-D and symptoms associated with dysmenorrhea in our study. The Vitamin-D replacement therapy led to a significant decrease in symptoms.

Abstract
Depression, a common mood disorder, involves anhedonia and defects in reward circuits and mesolimbic dopamine transmission in the striatum and nucleus accumbens (NAc). Active vitamin-D, (1,25-(OH)2 vitamin-D3), exerts protective and regulatory effects on the brain dopamine system. In this study, key depression-like symptoms were induced in rats by chronic mild-stress (CMS) and the comparative effect of treatment with 1,25-(OH)2 vitamin-D3 (5, 10 μg/kg, or vehicle; i.p., twice weekly) or fluoxetine (5 mg/kg or vehicle, i.p., daily) on anhedonic behavior, locomotor activity and anxiety-like behavior was examined using sucrose preference test (SPT), open field test (OFT) and novel object exploration test (NOT), respectively. We also measured serum corticosterone levels and dopamine transporter-immunoreactivity (DAT-ir) levels in NAc shell and core. CMS exposure for 3 weeks was followed by a SPT and thereafter CMS was continued for 5 weeks, along with vitamin-D or fluoxetine treatment and further testing, which was concluded with another SPT. Vitamin-D treatment enhanced sucrose preference (P < 0.01; an hedonic effect) and increased object exploration (P < 0.01) in CMS rats. CMS significantly reduced the level of DAT-ir in NAc (P < 0.0001). Vitamin-D treatment restored/increased DAT-ir levels (P < 0.0001) in CMS rat NAc (core/ shell), compared to levels in fluoxetine treated and non-treated CMS rats. Vitamin-D did not alter locomotor activity or produce an anxiolytic effect in the OFT. These data suggest that similar to the antidepressant, fluoxetine, regular vitamin-D treatment can improve 'anhedonia-like symptoms' in rats subjected to CMS, probably by regulating the effect of dopamine-related actions in the NAc.

Abstract
UV-radiations are the invisible part of light spectra having a wavelength between visible rays and X-rays. Based on wavelength, UV rays are subdivided into UV-A (320-400 nm), UV-B (280-320 nm) and UV-C (200-280 nm). Ultraviolet rays can have both harmful and beneficial effects. UV-C has the property of ionization thus acting as a strong mutagen, which can cause immune-mediated disease and cancer in adverse cases. Numbers of genetic factors have been identified in human involved in inducing skin cancer from UV-radiations. Certain heredity diseases have been found susceptible to UV-induced skin cancer. UV radiations activate the cutaneous immune system, which led to an inflammatory response by different mechanisms. The first line of defense mechanism against UV radiation is melanin (an epidermal pigment), and UV absorbing pigment of skin, which dissipate UV radiation as heat. Cell surface death receptor (e.g. Fas) of keratinocytes responds to UV-induced injury and elicits apoptosis to avoid malignant transformation. In addition to the formation of photo-dimers in the genome, UV also can induce mutation by generating ROS and nucleotides are highly susceptible to these free radical injuries. Melanocortin 1 receptor (MC1R) has been known to be implicated in different UV-induced damages such as pigmentation, adaptive tanning, and skin cancer. UV-B induces the formation of pre-vitamin D3 in the epidermal layer of skin. UV-induced tans act as a photoprotection by providing a sun protection factor (SPF) of 3-4 and epidermal hyperplasia. There is a need to prevent the harmful effects and harness the useful effects of UV radiations.

Abstract
Few studies have investigated the association between serum 25-hydroxyvitamin D (25[OH]D), vitamin D supplement and asthma control among adults. We aimed to examine whether low levels of serum 25(OH)D or not taking vitamin D supplement were associated with an increased risk of poorly controlled asthma among Norwegian adults with asthma. We used a definition of asthma control adapted from the Global Initiative for Asthma. We first examined cross-sectional associations between serum 25(OH)D (n = 806) or vitamin D supplement (n = 1179) and poorly controlled asthma. Next, among those with well controlled asthma at baseline, we examined prospective associations between serum 25(OH)D (n = 147) or vitamin D supplement (n = 208) and poorly controlled asthma at follow-up, approximately 11 years later. We estimated risk ratios (RR) and 95% confidence intervals (CI) with Poisson regression. The adjusted RR for poorly controlled asthma was 1.00 (95% CI, 0.89-1.13) for adults with serum 25(OH)D < 50 nmol/L in cross-sectional and 1.50 (95% CI, 0.46-4.95) in prospective analyses. The adjusted RR for poorly controlled asthma was 1.17 (95% CI 1.00-1.37) for non-users of vitamin D supplement in cross-sectional and 1.66 (95% CI 0.49-5.67) in prospective analyses. Our study did not show strong evidence that among adults with asthma, having a low serum 25(OH)D or being a non-user of vitamin D supplement was associated with an increased risk of poorly controlled asthma. Some point estimates indicated an increased risk, however our estimates were generally imprecise and further evidence is needed.

Abstract
Diabetes is a major risk factor for cardiovascular disease (CVD) including stroke, coronary heart disease, and peripheral artery disease. It remains a leading cause of mortality throughout the world, affecting both women and men. This investigation was aimed to study gender based differences in cardiovascular risk factors of adult population with type-2 diabetes mellitus (T2DM) and to check the correlation between serum HbA1C, lipid profile and serum vitamin D levels, in T2DM patients of Riyadh, Saudi Arabia. This hospital-based cross-sectional study involving subjects was divided into two gender based groups; normal male (800), diabetic male (800) and normal female (800) and T2DM females (800). Blood samples were analyzed for fasting glucose (FBG), HbA1c, total cholesterol (TC), triglycerides (Tg), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) and serum levels of 25(OH)-vitamin D in all groups. All the glycemic control parameters and lipid profile parameters were found to be significantly different in diabetic vs non-diabetic group (p < 0.001) in both genders. The results also show that vitamin D concentration decreased significantly (p < 0.001) in diabetic patients than the healthy individuals in both the genders. Vitamin-D and HbA1C were negatively correlated in both males and females in T2DM patients and significant at P < 0.05. Our study reveals that dyslipidemia remains one of the major risk factors of CVD in T2DM. In addition to dyslipidemia, decreased levels of vitamin-D associated with increased HbA1C alarms the early diagnosis of Type 2 Diabetes.

Abstract
Background Vitamin-D deficiency has been linked with impaired development in animal studies; however, the evidence from human studies is scanty. Evidence as to whether vitamin-D deficiency during early childhood affects growth is also limited and conflicting. We examined the extent to which vitamin-D deficiency (<10 ng/ml) is associated with neurodevelopment and physical growth in young children. Methods We used data from a randomized controlled trial (RCT) of daily folic acid and/ or vitamin B12 supplementation for six months in children aged 6 to 30 months conducted in Delhi, India. We measured vitamin-D status and neurodevelopment by the Ages and Stages Questionnaire-3 (ASQ-3) at 12 to 36 months of age. Multiple logistic and linear regressions were used to examine the association between vitamin-D deficiency at baseline and neurodevelopment and growth 6 months follow-up. Results 25-hydroxy-vitamin-D (25OHD) concentration was measured at baseline for 960 (96%) children. Of these, 331 (34.5%) children were vitamin-D deficient. The total and subscale (except for the Personal social scale) ASQ-3 scores, were not different between the vitamin-D deficient and non-deficient children. Vitamin-D deficiency was also not associated with physical growth at baseline and at follow -up. Conclusion Our data do not support the hypothesis that vitamin-D deficiency is associated with poor growth and neurodevelopment. Trial registration NCT00717730 and CTRI/2010/091/001090.

Abstract
Systematic administration of interferon-alpha (INF-alpha) is considered as the backbone of HCV therapy since 1991. Interferon (IFN)
therapy can cause vasculitis, glomerulonephritis, cryoglobulinemia and certain other autoimmune diseases such as sialoadentitis, lichen
planus and thyroiditis. Related to the factors of interferons, extensively studied gland is thyroid gland. A strong association was observed
between thyroid disease and HCV patient when they were exposed to IFN therapy. Vitamin D, malondialdehyde (MDA), thyroid
hormones and auto antibodies were biochemically assessed from the venous blood of seventy five HCV patients and fifty healthy controls.
The results of all parameters were analyzed by independent sample t-test. The results of the study demonstrated a clear picture that the
levels of vitamin D decreased as compared to control but increases in case of MDA. The levels of antibody titer represent that
thyroglobulin-antibody (TGAb) thyroid peroxidase-antibody (TPOAb) as well as thyroid stimulating hormone receptor-antibody
(TSHRAb) were raised in the patients suffering from HCV with thyroid dysfunction as compared to control. Similarly, the levels of thyroid
hormones were also elevated in the HCV patients. Antibodies generated against thyroidal enzymes leads to impaired function of these
enzymes thus causing decreased synthesis of thyroid hormones. As exogenous INF triggers the release of cytokines that mediate the
recruitment of immune cells with increased production of inflammatory markers lead to production of lytic granules which have direct
toxic action on thyroid cells and ultimately increased lipid peroxidation of thyrocytes. The results of the present study clearly
demonstrated that the decreased levels of vitamin D in HCV patients receiving IFN therapy were responsible to induce autoimmunity
against thyroid gland and adjutant therapy may be helpful to alleviate the possible thyroid disorders.

Abstract
Introduction Recent studies have shown that vitamin-D intake can improve skeletal muscle function and strength in frail vitamin-D insufficient individuals. We investigated whether vitamin-D intake can improve the muscular response to resistance training in healthy young and elderly individuals, respectively. Methods Healthy untrained young (n = 20, age 20–30) and elderly (n = 20, age 60–75) men were randomized to 16 weeks of daily supplementary intake of either 48 μg of vitamin-D + 800 mg calcium (Vitamin-D-group) or 800 mg calcium (Placebo-group) during a period and at a latitude of low sunlight (December-April, 56°N). During the last 12 weeks of the supplementation the subjects underwent progressive resistance training of the quadriceps muscle. Muscle hypertrophy, measured as changes in cross sectional area (CSA), and isometric strength of the quadriceps were determined. Muscle biopsies were analyzed for fiber type morphology changes and mRNA expression of vitamin-D receptor (VDR), cytochrome p450 27B1 (CYP27B1) and Myostatin. Results In the vitamin-D groups, serum 25(OH)D concentration increased significantly and at week 12 was significantly different from placebo in both young men (71.6 vs. 50.4 nmol/L, respectively) and elderly men (111.2 vs. 66.7 nmol/L, respectively). After 12 weeks of resistance training, quadriceps CSA and isometric strength increased compared to baseline in young (CSA p < 0.0001, strength p = 0.005) and elderly (CSA p = 0.001, strength p < 0.0001) with no difference between vitamin-D and placebo groups. Vitamin-D intake and resistance training increased strength/CSA in elderly compared to young (p = 0.008). In the young vitamin-D group, the change in fiber type IIa percentage was greater after 12 weeks training (p = 0.030) and Myostatin mRNA expression lower compared to the placebo group (p = 0.006). Neither resistance training nor vitamin-D intake changed VDR mRNA expression. Conclusion No additive effect of vitamin-D intake during 12 weeks of resistance training could be detected on either whole muscle hypertrophy or muscle strength, but improved muscle quality in elderly and fiber type morphology in young were observed, indicating an effect of vitamin-D on skeletal muscle remodeling.

Abstract
BACKGROUND & AIMS We implemented a prospective study among human immunodeficiency virus (HIV)-positive adults to examine the association between vitamin-D deficiency (VDD) and insufficiency (VDI) vs sufficiency (VDS) and CD4+T-cell improvement over 18 months of highly active antiretroviral therapy (HAART). METHODS We used data from a randomized placebo-controlled micronutrient trial with 25-hydroxy vitamin-D (25(OH)D) measured at enrollment in 398 adults. CD4+T-cell count was measured repeatedly at months 0, 3, 6, 12 and 18. Linear mixed models quantified the vitamin-D-related differences in CD4+T-cell count and associated 99% confidence intervals at baseline and respective follow-up intervals. RESULTS At baseline 23%, 60% and 17% of participants were VDS, VDI and VDD, respectively. Absolute CD4+T- cell counts recovered during follow-up were persistently lower for baseline VDD and VDI relative to VDS participants. The greatest deficit in absolute CD4+T-cells recovered occurred in VDD vs VDS participants with estimates ranging from a minimum deficit of 26 cells/μl (99% CI: -77, 26) to a maximum deficit of 65 cells/μl (99% CI: -125, -5.5) during follow-up. This VDD-associated lower absolute CD4+T-cell gain was strongest among patients 35 years old or younger and among participants with a baseline body mass index of less than 25 kg/m(2). CONCLUSIONS VDD is associated with lower absolute CD4+T-cell count recovery in HIV-positive patients on HAART. Vitamin-D supplementation may improve CD4+T-cell recovery during HAART. However, future intervention studies are needed to definitively evaluate the effectiveness of this vitamin as an adjunct therapy during HAART.

Abstract
INTRODUCTION Bronchial Asthma is a common chronic inflammatory disorder of the airways in childhood. Vitamin-D, required for bone mineralization, is also a potent immune system regulator having a potential role in various allergic diseases. This study was undertaken to determine the difference in serum levels of Vitamin-D in asthmatic children and to determine the association between vitamin-D and asthma in children. MATERIALS AND METHODS This cross-sectional study included 88 (44 asthmatic children and 44 healthy controls) children aged between 5 and 13 y. Serum 25-hydroxy vitamin-D levels were determined and compared between the two groups. The association between vitamin-D levels and lung function was studied in the asthmatic children. RESULTS Serum vitamin-D level was significantly lower in asthmatic children than in control group and in the asthmatic group, vitamin-D levels had a significant positive correlation with FEV1% and FEV1/FVC%. CONCLUSION Vitamin-D deficiency is highly prevalent in asthmatic children and is associated with airway limitation.

Abstract
BACKGROUND Obesity is increasing in children and it can cause many complications in adulthood, such as Diabetes mellitus (DM) and metabolic syndrome. In observational studies, vitamin-D was one of the factors which were found to be associated with obesity. AIMS To determine the association between body mass index (BMI) and serum level of vitamin-D in children who were outpatients at Taleghani Paediatric Hospital, Iran. SETTINGS AND DESIGN This was a cross-sectional observational study done on 215 children who were 2 to 7 y old, who were referred to Taleghani Hospital in winter (1391 solar calendar) 2013. MATERIALS AND METHODS In this cross-sectional study, anthropometric indices: weight, height and waist circumference were measured by using identical instruments. BMI was also determined as per CDC 2000 criteria. Vitamin-D levels were estimated by ELISA. STATISTICAL ANALYSIS Vitamin-D levels which were less than 20 nmol/L were considered as a deficiency, levels which were 20-30 nmol\L were considered as inadequate and those which were equal to or greater than 30 nmol\L were considered as sufficient. t-test, ANOVA and Pearson's correlation coefficient at a significant level of 0.05 were applied and data were analysed by using SPSS (version 16). RESULTS One hundred and twenty five children (47.4%) were males and the rest were females. One hundred eighty four children (85.6%) had vitamin-D deficiency and only 31 had adequate levels of vitamin-D. The prevalence of obesity and overweight were 27%, but considering the vitamin-D status, it was found to be insignificant. However, there was a linear relationship between waist circumference and serum vitamin-D (p<0.01). The means and standard deviations of serum vitamin-D levels in girls and boys were 22.76 ±11.62 and 23.46 ± 9.30 nmol/L and this difference was not significant. Vitamin-D levels found in the three ethnic groups of Fars, Turkmen and Sistani showed significant differences (p<0.002). CONCLUSIONS There was a high prevalence of vitamin-D deficiency in 2 to 7 year olds. There was no significant relationship between BMI and vitamin-D, but it was recorded in ethnic groups, and there was a correlation between waist circumference and vitamin-D levels. More exposure to sunlight and prescription of vitamin supplements were recommended.

Abstract
The etiopathogenesis of schizophrenia is poorly understood. Within the proposed "neurodegeneration paradigm", observations have been put forth for "accelerated aging" in this disorder. This proposition is largely based on the neuroscience research that demonstrates progressive changes in brain as well as other systemic abnormalities supportive of faster aging process in patients with this disorder. In this review, we have summarized the literature related to the concept of early aging in schizophrenia. These studies include P300 abnormalities & visual motion discrimination, neuroimaging findings, telomere dynamics as well as neuropathology of related brain regions. We also propose a role of vitamin D, neuroimmunological changes and elevated oxidative stress as well as mitochondrial dysfunction in addition to the above factors with 'vitamin-D deficiency' as the central paradox. Put together, the evidence supporting early aging in schizophrenia is compelling and this requires further systematic studies.

Abstract
An adequate phosphate balance is essential for the maintenance of skeletal growth, development and function. It is also crucial in basic cellular functions, ranging from cell signaling to energy metabolism. Bone-derived fibroblast growth factor 23 (FGF23), through activating FGF receptor system, plays an important role in the systemic regulation of phosphate metabolism. Under physiological conditions, FGF23 exerts serum phosphate-lowering effects by inducing urinary phosphate excretion. Increased FGF23 activities are associated with hypophosphatemic diseases (i.e., rickets/osteomalacia), while reduced FGF23 activity are linked to hyperphosphatemic diseases (i.e., tumoral calcinosis). Unlike most of the FGF family members, FGF23 needs klotho, as a co-factor to activate its receptor system. In vivo studies have convincingly demonstrated that, in absence of klotho, FGF23 is unable to influence systemic phosphate metabolism. Available information suggests that interactions of FGF23, klotho, and FGFRs regulate renal phosphate metabolism by suppressing sodium-phosphate transporters in the proximal tubular epithelial cells. This article briefly summarizes how bone-kidney communication contributes to physiologic phosphate balance.

Abstract
Vitamin-D supplementation in vitamin-D insufficient/deficient prediabetes individuals is associated with significantly lower progression to diabetes (6/55 vs. 13/49; p=0.04) and higher reversal to normoglycemia (23/55 vs. 10/49; p=0.02), associated with decreased insulin resistance and systemic inflammation (TNFα and IL6). Baseline vitamin-D and 2h blood glucose independently predicted progression to diabetes.

Abstract
BACKGROUND Prevalence of polycystic ovary syndrome (PCOs) is increasing particularly among the female adolescents and young women. It has been hypothesized that disturbance in calcium and vitamin-D metabolism may affect the symptoms of this syndrome. This study was designed to investigate the relationship between vitamin-D and calcium with metabolic parameters and other characteristics of the PCOs. METHODS The study included 192 Iranian girls (16-20 years old), of whom 104 had PCOs and 88 were non-PCOs controls. Serum 25(OH) D and calcium level was measured. Anthropometric components, endocrine, metabolic components and insulin resistance were determined in PCOs subjects. RESULTS Mean 25 (OH) D was significantly lower in cases (9.7±4.8) than controls (12.3±11.9) but calcium level did not differ between the two groups (9.3±0.3 vs 9.4±0.4). No significant correlations were found between 25(OH) D levels and lipid profile, FBS, fasting insulin endocrine parameters such as testosterone, free testosterone, FSH, LH, and prolactin. CONCLUSION Although hypovitamionos D was common is PCOs but did not correlate with clinical features or complications of obesity and insulin resistance PCO like severity of syndrome between vitamin-D deficiency and its severity with some features and complications of PCOs including obesity, insulin resistance.
