TV Viewing versus Play - Trends and Impact on Obesity

A cross sectional descriptive study was conducted involving 10000 students from randomly selected government and private schools of Amritsar district to identify the trends of TV viewing and playing in school children aged 5 years and above, to compare TV viewing in both sexes, different age groups and urban versus rural children and to study the impact of TV viewing and playing on obesity in children. The results showed that TV viewing has replaced outdoor playing in most children, irrespective of age, sex and residence. A positive relation between TV viewing and obesity was also documented

Factors Contributing to Psycho-Social Ill-Health in Male Adolescents

Objective: To study the prevalence of psychosocial problems in male adolescents and find out various factors contributing to psycho-social ill health. Methods: 500 adolescents were interviewed using a pre-tested structured questionnaire to elicit the information about the psychosocial problems including depression, suicidal thoughts and suicidal attempts. Association of academic performance, family problems, psychological problems and substance abuse was also included. Results: More than one third (39.6%) adolescents were having psychological problems. These problems were significantly higher in middle adolescence (14-16 years), large extended families (> 8 members) and lower socioeconomic status. Residence had no significant relation to psychological problems in the adolescents. On correlation, these adolescents with psychological problems were having significantly more academic problems, family disputes, domestic violence, lesser number of close friends and greater substance abuse. Conclusion: Considering that male adolescents from large families with lesser education and lower income had higher prevalence of psychosocial problems, it is essential for health care planners to design comprehensive family and health education programs for the adolescents. The family support, teacher student rapport and peer group communication should be strengthened to counteract unsafe behaviours in the adolescents

Potentially fatal tricuspid valve aspergilloma detected after laparoscopic abdominal surgery

Fungal endocarditis accounts for 1.3-6% of all cases of infective endocarditis. The most common causative organism is Candida, followed by Aspergillus and other mould fungi. Aspergillus endocarditis is usually associated with high morbidity and mortality. Establishing a definitive and timely diagnosis remains difficult and there are many reports of undetected aspergillomas leading to fatalities in the perioperative period. We present a case report of preoperatively undiagnosed large mobile tricuspid valve aspergilloma obstructing the right ventricular inlet, diagnosed incidentally on the second postoperative day after laparoscopic pancreatic abscess drainage. The patient was successfully managed with emergency open-heart surgery and systemic antifungal agents in the postoperative period.Keywords: Infective endocarditis, aspergilloma, tricuspid valu

Novel role for the innate immune receptor toll-like receptor 4 (TLR4) in the regulation of the wnt signaling pathway and photoreceptor apoptosis

Recent evidence has implicated innate immunity in regulating neuronal survival in the brain during stroke and other neurodegenerations. Photoreceptors are specialized light-detecting neurons in the retina that are essential for vision. In this study, we investigated the role of the innate immunity receptor TLR4 in photoreceptors. TLR4 activation by lipopolysaccharide (LPS) significantly reduced the survival of cultured mouse photoreceptors exposed to oxidative stress. With respect to mechanism, TLR4 suppressed Wnt signaling, decreased phosphorylation and activation of the Wnt receptor LRP6, and blocked the protective effect of the Wnt3a ligand. Paradoxically, TLR4 activation prior to oxidative injury protected photoreceptors, in a phenomenon known as preconditioning. Expression of TNFα and its receptors TNFR1 and TNFR2 decreased during preconditioning, and preconditioning was mimicked by TNFα antagonists, but was independent of Wnt signaling. Therefore, TLR4 is a novel regulator of photoreceptor survival that acts through the Wnt and TNFα pathways. © 2012 Yi et al

Functional abilities, respiratory and cardiac function in a large cohort of adults with Duchenne muscular dystrophy treated with glucocorticoids

\ua9 2024 The Authors. European Journal of Neurology published by John Wiley & Sons Ltd on behalf of European Academy of Neurology.Background and purpose: The transition to adult services, and subsequent glucocorticoid management, is critical in adults with Duchenne muscular dystrophy. This study aims (1) to describe treatment, functional abilities, respiratory and cardiac status during transition to adulthood and adult stages; and (2) to explore the association between glucocorticoid treatment after loss of ambulation (LOA) and late-stage clinical outcomes. Methods: This was a retrospective single-centre study on individuals with Duchenne muscular dystrophy (≥16 years old) between 1986 and 2022. Logistic regression, Cox proportional hazards models and survival analyses were conducted utilizing data from clinical records. Results: In all, 112 individuals were included. Mean age was 23.4 \ub1 5.2 years and mean follow-up was 18.5 \ub1 5.5 years. At last assessment, 47.2% were on glucocorticoids; the mean dose of prednisone was 0.38 \ub1 0.13 mg/kg/day and of deflazacort 0.43 \ub1 0.16 mg/kg/day. At age 16 years, motor function limitations included using a manual wheelchair (89.7%), standing (87.9%), transferring from a wheelchair (86.2%) and turning in bed (53.4%); 77.5% had a peak cough flow <270 L/min, 53.3% a forced vital capacity percentage of predicted <50% and 40.3% a left ventricular ejection fraction <50%. Glucocorticoids after LOA reduced the risk and delayed the time to difficulties balancing in the wheelchair, loss of hand to mouth function, forced vital capacity percentage of predicted <30% and forced vital capacity <1 L and were associated with lower frequency of left ventricular ejection fraction <50%, without differences between prednisone and deflazacort. Glucocorticoid dose did not differ by functional, respiratory or cardiac status. Conclusion: Glucocorticoids after LOA preserve late-stage functional abilities, respiratory and cardiac function. It is suggested using functional abilities, respiratory and cardiac status at transition stages for adult services planning

Unreported yet massive deforestation driving loss of endemic biodiversity in Indian Himalaya

The original publication is available at www.springerlink.comDeforestation is a primary driver of biotic extinctions in the tropics. The impacts of deforestation in tropical biodiversity hotspots are of particular concern because these regions contain high concentrations of globally endemic species. However, the effects of large-scale deforestation on native biotas within the biodiversity hotspot of Himalaya remain poorly documented. Here we report on an alarming trend of deforestation in the Indian Himalaya and project the likely consequential extinctions of endemic taxa (species and subspecies) by 2100 across a broad range of taxonomic groups, including gymnosperms, angiosperms, fishes, amphibians, reptiles, birds, and mammals. With the current level of deforestation, by 2100 only about 10% of the land area of the Indian Himalaya will be covered by dense forest (>40% canopy cover)—a scenario in which almost a quarter of the endemic species could be wiped out, including 366 endemic vascular plant taxa and 35 endemic vertebrate taxa. We also show that inaccurate reporting of forest cover data by governmental institutions can result in underestimations of the biological impacts of deforestation, as well as potential miscalculations in land-use decisions (e.g., the construction of hydroelectric dams). Large-scale conservation efforts, including forest protection and reforestation, are urgently needed to avoid the impending deforestation-driven biodiversity losses in the Himalaya.M. K.
