The Role of Genetic, Dietary and Lifestyle Factors in Pediatric Metabolic Syndrome: A Review of the Literature from Prenatal to Adolescence

The metabolic syndrome (MetS) is described as a cluster of health conditions that are associated with an increased risk of cardiovascular disease. The clinical diagnosis of MetS in pediatrics is challenging due to differing criteria, although the estimated prevalence continues to rise. The increased prevalence of childhood obesity and insulin resistance, in both developed and developing countries, is believed to be a major contributor to MetS diagnosis in children. We review the current literature surrounding genetic predisposition, maternal influence, epigenetics, environmental and lifestyle factors pertaining to pediatric MetS with a specific emphasis on obesity and insulin resistance. We highlight and discuss recent, key studies in prenatal through to adolescent populations and review evidence suggesting that children may be pre-disposed to obesity and insulin resistance, prenatally. We also discuss several key lifestyle drivers of these conditions including poor nutrition and dietary habits, insufficient physical activity, use of electronic devices, over-consumption of caffeinated and/or sugar-sweetened beverages, as well as the importance of sleep during childhood and adolescence in relation to metabolic health. We conclude with recommendations for preventable methods to tackle this growing pediatric public health issue, which, if current trends continue, will undoubtedly compromise the health and longevity of the next adult generation.

Mushroom Poisoning in the Northeast of Iran; a Retrospective 6-Year Epidemiologic Study

Introduction: Toxic mushrooms are distributed across the globe with over 5000 species. Among them, 100 species are responsible for most of the cases of mushroom poisoning. This study aimed to evaluate the epidemiologic pattern of mushroom poisoning among patients referred to the main toxicology center of Mashhad province located in North-east of Iran.Method: This cross-sectional study was conducted on patients with final diagnosis of mushroom poisoning referred to the toxicology center of Mashhad, Iran, from February 2005 to 2011. Patients’ demographic characteristics, clinical presentations, laboratory findings, outcomes, and therapeutic measures were collected using a predesigned checklist and searching patient’s profile. Results: 32 cases with the mean age of 24.6 ± 16.7 years were presented to the toxicology center following mushroom poisoning (59% female). Mushroom poisoning accounted for 0.1% of all admitted cases. The mean time elapsed from consumption to referral to poisoning department was 61.9 ± 49.4 hours. 19 (59%) cases were discharged with complete recovery, 7 (22%) expired, and 6 (19%) cases left hospital against medical advice. Mushroom poisoning mortality accounted for 1.5% of deceased cases in the studied center. There was significant relationship between mortality rate and higher values of INR (p = 0.035), PT (p = 0.011) and PTT (p = 0.003). Likewise, there was significant relationship between the need for mechanical ventilation and higher values of INR (p = 0.035), PT (p = 0.006) and PTT (p = 0.014). The relationships between the need for ICU admission, mechanical ventilation, and mortality rate with the rise of hepatic transaminases and serum bilirubin were not significant.Conclusion: Based on the findings, the prevalence of mushroom poisoning among patients referred to Mashhad toxicology center was very low (0.1%), but with a high mortality rate of 22%. Nausea and vomiting were the most common early symptoms of intoxication and higher values of coagulation profile were correlated with poor outcome

Acute Myocardial Infarction following Naltrexone Consumption; a Case Report

Cardiovascular effects of opioid withdrawal have long been studied. It was reported that patients with underlying ischemic heart disease and atherosclerotic vessels may be complicated by a sudden physical and emotional stress due to withdrawal syndrome. But some other believes sudden increase in catecholamine level as a sympathetic overflow might effect on heart with and without underlying ischemia. In the current study, a patient on methadone maintenance therapy (MMT) who experienced myocardial infarction (MI) after taking naltrexone was described

What are the design principles of Healing Gardens

According to European Agency for Health at Work (2011), Stress is one of the biggest health and safety challenges in Europe and “[it] is the second most reported work-related health problem, affecting 22% of workers from EU 27 (in 2005).” Nature by having special futures has positive effects on human’s health and can be a place for restoration from stress. Healing gardens for people who are suffering from stress-related disease is a concept which tries to take advantage of being passive and active in natural space. The aim of this thesis is to look at the design principles of this kind of healing garden with the case study of Torup Healing. The result which is mainly extracted from interviews of designers, shows that there are two main parts, first before starting the design process “what is important to know” and “important factors” while planning it. The study got two significant elements; “society” and “establishment” as new findings through the research which might not be called principles but they are as important as principles and should be taken into account during the process of design

Growth inhibition of androgen-responsive prostate cancer cells with brefeldin A targeting cell cycle and androgen receptor

<p>Abstract</p> <p>Background</p> <p>Androgen ablation is one of the viable therapeutic options for patients with primary hormone (androgen)-dependent prostate cancer. However, an antibiotic brefeldin A (BFA) has been shown to exhibit the growth inhibitory effect on human cancer cells. We thus investigated if BFA might inhibit proliferation of androgen-responsive prostate cancer LNCaP cells and also explored how it would be carried out, focusing on cell cycle and androgen receptor (AR).</p> <p>Methods</p> <p>Androgen-mediated cellular events in LNCaP cells were induced using 5α-dihydrotestosterone (DHT) as an androgenic mediator. Effects of BFA on non-DHT-stimulated or DHT-stimulated cell growth were assessed. Its growth inhibitory mechanism(s) was further explored; performing cell cycle analysis on a flow cytometer, assessing AR activity by AR binding assay, and analyzing AR protein expression using Western blot analysis.</p> <p>Results</p> <p>DHT (1 nM) was capable of stimulating LNCaP cell growth by ~40% greater than non-stimulated controls, whereas BFA (30 ng/ml) completely inhibited such DHT-stimulated proliferation. Cell cycle analysis showed that this BFA-induced growth inhibition was associated with a ~75% reduction in the cell number in the S phase and a concomitant increase in the G₁cell number, indicating a G₁cell cycle arrest. This was further confirmed by the modulations of specific cell cycle regulators (CDK2, CDK4, cyclin D₁, and p21^WAF1), revealed by Western blots. In addition, the growth inhibition induced by BFA was accompanied by a profound (~90%) loss in AR activity, which would be presumably attributed to the significantly reduced cellular AR protein level.</p> <p>Conclusions</p> <p>This study demonstrates that BFA has a potent growth inhibitory activity, capable of completely inhibiting DHT (androgen)-stimulated LNCaP proliferation. Such inhibitory action of BFA appears to target cell cycle and AR: BFA led to a G₁cell cycle arrest and the down-regulation of AR activity/expression, possibly accounting for its primary growth inhibitory mechanism. Thus, it is conceivable that BFA may provide a more effective therapeutic modality for patients with hormone-dependent prostate cancer.</p

Editorial: Exercise prescription in metabolic diseases: An efficient medicine towards prevention and cure

Metabolic disease encompasses excess adiposity, dysglycaemia, type 2 diabetes mellitus, dyslipidaemia, non-alcoholic fatty liver disease (NAFLD), and hypertension that translate to excess cardiovascular disease and increased mortality. The prevalence of metabolic disease is increasing in prevalence, driven by excessive intake of energy dense food and physical inactivity, and is a major challenge for healthcare services. Physical inactivity is a major contributor to the development of metabolic disease and regular exercise can prevent, delay, and control metabolic disease
