Prevalence of overweight and obesity in adolescent Tehrani students, 2000-2001: an epidemic health problem.

Abstract: Department of Community Nutrition,Faculty of Nutrition Sciences and Food Technology, Shaheed Beheshti University of Medical Sciences and HealthServices, Tehran, IranSubmitted 28 April 2003: Accepted 1 December 2003AbstractObjective: Overweight has become a public health problem in most developingcountries. Evidence suggests that adolescence is a critical period in determiningadulthood obesity and its complications. The present study was carried out to assessthe prevalence of overweight and obesity among secondary school students.Design and setting: This descriptive study was conducted in Tehran city, 2000–2001.Body weight and height were measured and body mass index (BMI) valueswere calculated. Underweight, overweight and obesity were defined as ,5th, $85thand $95th percentile, respectively, of age- and sex-specific BMI values fromthe National Center for Health Statistics/Centers for Disease Control andPrevention (2000).Subjects: Using a multistage sampling method, 2321 students (1068 males and 1253females) aged 11–16 years were assessed in Tehran, the capital city of Iran.Results: The overall prevalences of overweight and obesity were 21.1 and 7.8%,respectively. The prevalence of overweight among girl students (i.e. 23.1%;95% confidence interval (CI) 20.8–25.4) was significantly higher than that amongboys (i.e. 18.8%; 95% CI 16.5–21.1, P ¼ 0.01) even after adjustment for age(odds ratio 1.26, 95% CI 1.03–1.55, P ¼ 0.02). No significant risk of obesityassociated with age was found in girls or boys. In both sexes, median values ofage-specific BMI in this study were statistically higher than corresponding valuescollected in Tehrani adolescents 10 years ago (P ¼ 0.03). Similarly, a significantdifference was seen between girl students in this study and the referencepopulation (P ¼ 0.03).Conclusion: According to this study, overweight, especially in girls, should beconsidered an epidemic health problem among adolescent students in Tehran.KeywordsAdolescenceOverweightObesityTehranOverweight, as a main feature of epidemiologicaltransition, has increased in most developing countriesover the last two decades

Current and Upcoming Therapies for Ocular Surface Chemical Injuries.

Abstract: Chemical injuries frequently result in vision loss, disfigurement, and challenging ocular surface complications. Acute interventions are directed at decreasing the extent of the injury, suppressing inflammation, and promoting ocular surface re-epithelialization. Chronically, management involves controlling inflammation along with rehabilitation and reconstruction of the ocular surface. Future therapies aimed at inhibiting neovascularization and promoting ocular surface regeneration should provide more effective treatment options for the management of ocular chemical injuries.

Why the immune system fails to mount an adaptive immune response to a COVID-19 infection.

Abstract: The Covid-19 pandemic has already affected many thousands of people and has become the greatest health challenge worldwide [1]. The range of clinical presentations varies from asymptomatic and mild clinical symptoms to acute respiratory-distress syndrome (ARDS) and death. Due to the unknown number of asymptomatic viral-shedding and pauci-symptomatic people in the community, the total number of infections is uncertain. As yet, effective treatment is unavailable. However, the results of preliminary studies and clinical trials are improving our understanding of the pathogenesis and treatment of Covid-19. Herein, we share our personal opinions on the immunopathogenesis of this infection.
