#1
Scott A Booth, Fadi J Charchar
Telomeres are repetitive nucleoprotein structures at chromosome ends and a decrease in the number of these repeats, known as a reduction in telomere length (TL), triggers cellular senescence and apoptosis. Heart disease, the worldwide leading cause of death, often results from the loss of cardiac cells which could be explained by decreases in TL. Due to the cell-specific regulation of TL, this review focuses on studies that have measured telomeres in heart cells and critically assesses the relationship between cardiac TL and heart function...

The purpose of the present study was to better understand the role of sweet taste perception in dietary behavior and body weight in outbred Sprague-Dawley phenotypic obesity prone and obesity resistant rats by measuring sucrose taste sensitivity using a conditioned taste aversion paradigm. Rats were given a high fat diet for 2 weeks and were assigned as obesity-prone (P, upper tertile) or obesity-resistant (R, lower tertile) based on weight gain. Each group were then given either chow (C, 10% fat) or the high fat diet (F, 46% fat) for the remainder of the experiment (∼18 weeks) such that there were four groups - obesity prone on chow (C-P), obesity prone on high fat (H-P), obesity resistant on chow (C-R), obesity resistant on high fat (H-R)...

The circadian system plays a role in regulating metabolism. Night-shift work, a form of circadian misalignment, is associated with increased type 2 diabetes risk. This study aimed to determine if night-shift workers with type 2 diabetes experience poorer glycaemic control than non-shift workers. Patients with type 2 diabetes (104 unemployed, 85 day workers and 60 night-shift workers) participated. Sleep duration, sleep quality, morningness-eveningness preference, depressive symptoms and dietary intake were assessed using standardized questionnaires...

Lifestyle intervention can be useful across all the spectrum of NAFLD patients. Losing weight decreases cardiovascular / diabetes risk and also regresses liver disease. Weight reductions of ≥ 10% are required for inducing near universal NASH resolution or fibrosis improvement by at least one stage. However, modest weight losses (>5%) also produce important benefits on NAS and its components. In addition, to improve the success of this intervention we need to explore, beyond total calories and type of weight loss diet, the role of micro and macronutrients, evidence-based benefits of physical activity and exercise and finally supporting these modifications through established behaviour change models and techniques...

BACKGROUND: People may have different responses to the same environmental changes. It has been reported that genome variations may be responsible for these differences. Also, HDL subfractions may be influenced by different genetic variations. The aim of the present study was to determine gene-diet interactions and to evaluate the influence of weight loss on HDL subfractions between two genotypes of -265 T>C APOA-II polymorphism. METHODS: In the present study, 56 overweight and obese patients with type 2 diabetes mellitus were selected from 697 genotype-specified subjects...

OBJECTIVE: As obesity rates continue to climb in America, much of the blame has fallen on the high-calorie meals at popular chain restaurants. Many restaurants have responded by offering "healthy" menu options. Yet menus' descriptions of healthy options may be less attractive than their descriptions of less healthy, standard options. This study examined the hypothesis that the words describing items in healthy menu sections are less appealing than the words describing items in standard menu sections...

Calorie restriction (CR) extends lifespan and has been shown to reduce age-related diseases including cancer, diabetes, and cardiovascular and neurodegenerative diseases in experimental models. Recent translational studies have tested the potential of CR or CR mimetics as adjuvant therapies to enhance the efficacy of chemotherapy, radiation therapy, and novel immunotherapies. Chronic CR is challenging to employ in cancer patients, and therefore intermittent fasting, CR mimetic drugs, or alternative diets (such as a ketogenic diet), may be more suitable...

Although uncommon, kwashiorkor continues to occur in developed, but mainly in developing nations. It is a type of protein-calorie malnutrition that occurs in the setting of insufficient protein intake in the presence of sufficient caloric intake. Skin and hair changes should prompt a thorough dietary history and appropriate dietary intervention. We report a case of a 12-month old girl in Belo Horizonte, Minas Gerais, Brazil, who presented with diffuse edema, desquamation, and irritability misdiagnosed as atopic dermatitis...

The hedonic component of the feeding behavior involves the mesolimbic reward system and resembles addictions. Nowadays, the excessive consumption of sucrose is considered addictive. The Wistar-Kyoto (WKY) rat strain is prone to develop anxiety and addiction-like behavior; nevertheless, a lack of information regarding their vulnerability to develop sugar binging-like behavior (SBLB) and how it affects the reward system persist. Therefore, the first aim of the present study was to compare the different predisposition of two rat strains, Wistar (W) and WKY to develop the SBLB in female and male rats...

Raj Shah, Danielle Witt, Talal Asif, Fahad F Mir
Ipilimumab is a human monoclonal antibody that functions as a cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) inhibitor that is used to treat malignant melanoma. Due to ipilimumab's removal of immune regulation, specifically through the inactivation of CTLA-4, it is commonly associated with inflammatory and autoimmune events. Gastrointestinal (GI) related immune-related adverse events such as diarrhea occur in 29% of patients with 7.6% of patients specifically suffering from colitis. We describe a case of colonic perforation with ipilimumab use...
