Budding adult hypertensives with modifiable risk factors: "Catch them young"

Cardiovascular risk factors of hypertension, smoking and obesity: Emerging concerns among Pathan and Persian young adults?

Background: Hypertension was considered as a disease of the elderly but due to unhealthy dietary and lifestyle changes its incidence has increased in younger population. Smoking and obesity are emerging concerns the world is facing globally in younger age groups. This study is therefore aimed to identify these cardiovascular risk factors among Pathan and Persian young adults.

Methods: It was a cross-sectional study carried out at multiple undergraduate, postgraduate educational institutes and hospitals using non-probability convenient sampling among young adults aged between 15 to 40 years for a period of six months from Apr 1st, 2017 to Sep 30th, 2017. Mean±SD was calculated for continuous variables and categorical variables were expressed as frequencies. Chi-square test and Fisher exact test were used for statistical analysis.

Results: A total of 708 subjects were included. Mean±SD age was 26.12±3.7 years. Out of 708, 300(42.37%) were smokers with 209 (29.52%) active and 91 (12.85%) passive smokers. Among smokers, 216 (30.5%) were males while 84 (11.87%) were females. A total of 432 (61.02%) subjects were not doing any exercise, and 636 (89.83%) were consuming junk food. A total of 165 (23.3%) subjects were overweight, and 15 (2.1%) were obese. Stage-1 hypertension was present in 72 (10.2%), while 16 (2.25%) subjects had stage-2 hypertension.

Conclusion: There is an increased prevalence of cardiovascular risk factors which includes hypertension, smoking, and obesity among Pathan and Persian young adults.

Immunohistochemical Staining for Uroguanylin, a Satiety Hormone, is Decreased in Intestinal Tissue Specimens From Female Adolescents With Obesity

Gastrointestinal tract-secreted satiety hormones play a significant role in one of the largest health-care challenges for children and adults, obesity. Recent studies in mice identified a novel role for uroguanylin, the endogenous intestinal hormone that binds guanylyl cyclase C (GUCY2C), in regulating satiety via a gut-brain signaling pathway. Mice bred without GUCY2C receptors over-ate and developed obesity. We hypothesized that intestinal uroguanylin expression in pediatric patients with obesity would be lower than patients without obesity, and we attempted to examine the difference with immunohistochemistry. Retrospective chart review of gastrointestinal endoscopic procedures at an academic children's hospital identified patients with normal pathology findings on biopsy. Children aged 8-17 were included in the review; we analyzed biopsy samples from 20 matched pairs that differed only by body mass index (BMI)-for-age (average: 25%-75% vs. high: >95%). Biopsies of the duodenum, terminal ileum, ascending colon, and descending colon were subjected to immunohistochemistry for GUCY2C, uroguanylin, and the endogenous colonic hormone, guanylin. Intensity staining of all specimens was scored by a blinded pathologist. The overall staining intensity for females with high BMI-for-age was less for uroguanylin and guanylin as compared to average BMI-for-age females while GUCY2C staining was equal. Males did not exhibit different staining intensities for uroguanylin or guanylin. More matched female pairs had greater uroguanylin and guanylin staining in the average BMI-for-age cohort. The intestinal expression of uroguanylin, a key satiety hormone, appears to be diminished in female pediatric patients in the setting of obesity.
