Introduction: Adolescence is a critical period for the accrual of bone mass. However, few studies have assessed the bone geometry in slum-dwelling girls/young women. We thus conducted this study: (1) to assess bone health in Indian adolescent girls and young women residing in slum vs nonslum (NS) areas and (2) to identify factors associated with poor bone health. Methods: This cross-sectional case–control study was performed on 110 apparently healthy unmarried, nonpregnant, nonlactating, postmenarchal adolescent girls and young women aged 11 to 24 years residing in urban slums with the same number of age-matched controls from NS areas. Anthropometric, dietary, physical-activity and bone-health parameters (using dual-energy X-ray absorptiometry and peripheral quantitative computed tomography—DXA and pQCT—respectively) were evaluated using standard protocols. A P value of < 0.05 was considered statistically significant. Results: Slum girls were significantly shorter and lighter and had lower dietary intakes of calcium and protein after adjusting for total daily calorie intake than NS girls (P < 0.05). Areal bone-mineral density (BMD) at lumber spine (0.940 ± 0.13 vs1.042 ± 0.15 g/cm2), femur and total body (less-head), bone-mineral apparent density adjusted for volume at the lumbar spine (0.295 ± 0.04 vs 0.319 ± 0.04 g/cm3) and height-adjusted bone density at femur (0.862 ± 0.011 vs 0.905 ± 0.011 g/cm2) were significantly lower in slum dwelling participants as compared to their NS counterparts (P < 0.05). After adjusting for confounders like sunlight exposure, anthropometric parameters and dietary calcium intake, area of dwelling was still a significant factor for the difference in BMD. Conclusions: The potential determinants of poor bone density and geometry in girls and young women residing in slums include residential location, dietary habits, and physical activity levels. Despite adjustments for confounding factors, differences in bone health between those in slum and nonslum areas suggest adaptations developed over generations of deprivation in these individuals, necessitating urgent intervention.

Objective: To assess the weight velocity and the age at peak weight velocity and to construct weight velocity percentiles in 4–17-year-old apparently healthy Indian children. Method: This longitudinal study enrolled 1045 children (588 boys) aged 4–17 years from Pune belonging to middle and upper socioeconomic class. The study parameters included annual height and weight measurements recorded longitudinally from 2007 to 2013. A total of 5225 weight velocity measurements (2940 on boys) were computed. Age- and gender-specific smoothened weight velocity percentiles (3rd, 10th, 25th, 50th, 75th, 90th and 97th) were constructed using LMS chart maker. Results: The median weight velocity was low in boys and girls at 4 years, thereafter it increased to a peak of 4.6 kg/year at 13 years in boys, then declined to 1.1 kg/year at 17.5 years. In girls, median weight velocity peaked to 4.0 kg/year at 11 years, then declined to 0.8 kg/year at 17.5 years. Peak velocity-centred analysis revealed higher peak weight velocities of 7.5 kg/year at 13.1 years and 6.6 kg/year at 12 years in boys and girls respectively. Conclusion: Weight velocity percentiles are presented for 4–17-year-old apparently healthy Indian children. [ABSTRACT FROM AUTHOR]

Wolfram syndrome is characterised by insulin-dependent diabetes (IDDM), diabetes insipidus (DI), optic atrophy, sensorineural deafness and neurocognitive disorders. The DIDMOAD acronym has been recently modified to DIDMOAUD suggesting the rising awareness of the prevalence of urinary tract dysfunction (UD). End stage renal disease is the commonest cause of mortality in Wolfram syndrome. We present a case series with main objective of long term follow up in four children having Wolfram syndrome with evaluation of their urodynamic profile. A prospective follow up of four genetically proven children with Wolfram syndrome presenting to a tertiary care pediatric diabetes clinic in Pune, India was conducted. Their clinical, and urodynamic parameters were reviewed. IDDM, in the first decade, was the initial presentation in all the four children (three male and one female). Three children had persistent polyuria and polydipsia despite having optimum glycemic control; hence were diagnosed to have DI and treated with desmopressin. All four patients entered spontaneous puberty. All patients had homozygous mutation in WFS1 gene; three with exon 8 and one with exon 6 novel mutations. These children with symptoms of lower urinary tract malfunction were further evaluated with urodynamic studies; two of them had hypocontractile detrusor and another had sphincter-detrusor dyssynergia. Patients with hypocontractile bladder were taught clean intermittent catheterization and the use of overnight drain. We report a novel homozygous deletion in exon 6 of WFS-1 gene. The importance of evaluation of lower urinary tract malfunction is highlighted by our case series. The final bladder outcome in our cases was a poorly contractile bladder in three patients.

Introduction: Type 1 diabetes mellitus (T1DM) occurs in genetically susceptible individuals due to certain environmental triggers causing destruction of insulin secreting beta cells. One of the environmental triggers studied recently in the pathogenesis and progression of T1DM is the role of gut microbiome. Objectives: (1) To compare the gut microbiome profile of T1DM children with healthy age, gender, and body mass index (BMI) matched controls. (2) To assess the relationship of abundance of genera with glycemic control in children with T1DM. Methods: Cross‐sectional, case–control study. Sixty‐eight children with T1DM and 61 age‐, gender‐, and BMI‐matched healthy controls were enrolled. QIAamp Fast DNA Stool Mini kit protocol and reagents were used for DNA isolation and Miseq sequencing platform for targeted gene sequencing. Results: Alpha and beta diversity analysis showed no significant differences in the abundance of microbes between the groups. At phylum level, Firmicutes was the dominant phylum followed by Actinobacteria and Bacteroidota in both groups. Analysis of microbiome at the genera level showed that percentage abundance for Parasutterella was higher in children with T1DM as compared to the healthy group (p <.05). A linear regression analysis showed that increase in abundance of Haemophilus (adjusted R2 = −1.481 p <.007) was associated with a significant decrease in glycated hemoglobin (HbA1c) concentrations (p <.05). Conclusion: Our comparative study of gut microbiome profile showed significant differences in the taxonomial composition between Indian children with T1DM and healthy controls. Short chain fatty acid producers may play an important role in glycemic control. [ABSTRACT FROM AUTHOR]

To assess auxological parameters, adult height outcome and its determinants in Indian girls with idiopathic central precocious puberty (iCPP) treated with gonadotropin-releasing hormone analogues (GnRHa). Retrospective study. Inclusion: data on girls with iCPP from initiation to stopping GnRHa (n=179). Exclusion: boys, peripheral, organic central precocity. Mean age of starting GnRHa: 8.2± 1.1 years, duration: 2.8± 1.2 years. 11.7 % had attained menarche at first presentation. The difference between bone (BA) and chronological (CA) ages reduced significantly from 2.6± 0.9 years (onset) to 1.6± 0.8 years (cessation). Weight, BMI Z-scores increased (p<0.01), height Z-scores decreased (0.8 vs. 0.6; p<0.01), predicted adult height (PAH) and Z-scores improved by 3.5 cm, 0.5 SDS following treatment (p<0.01). Overweight/obese girls (vs. normal BMI) were taller, with more advanced BA at starting (height Z-score: 0.7 vs. 1.0, BA-CA: 2.2 vs. 2.9 years), stopping (height Z-score: 0.5 vs. 0.9, BA–CA: 1.4 vs. 1.9 years) treatment, but showed no difference in PAH at starting, stopping treatment. Adult height data (n=58) revealed 1.9 cm gain above target height. Adult height Z-scores significantly exceeded target height Z-scores (p<0.01). Mean adult height (157.1± 5.8 cm) crossed PAH at starting treatment (155.9± 6.4 cm) but remained 1.6 cm lesser than PAH at cessation. Adult weight, BMI Z-scores (−0.2± 1.3, −0.1± 1.2) were significantly lower (p<0.01) than those at stopping GnRHa. Height gain adjusted for age at starting GnRHa correlated negatively with height, weight, BMI, Tanner-staging, BA, FSH, Estradiol at treatment onset, BA at cessation, and correlated positively with treatment duration. GnRHa treatment in Indian girls with iCPP resulted in improved PAH, decelerated bone age advancement and growth velocity. Most girls achieved adult height within target range, surpassing PAH at treatment initiation. Lesser anthropometric, sexual, skeletal maturity, lower baseline FSH, estradiol, longer treatment duration, less advanced BA at stopping GnRHa may translate into better adult height outcomes.
