PURPOSE OF REVIEW: Cachexia is a negative prognostic factor in cancer patients. The pathogenesis is related to a variable combination of reduced food intake and metabolic changes. However, whether nutritional support may contribute to effectively prevent and treat cachexia remains a debated issue. RECENT FINDINGS: Consistent evidence demonstrates that anabolic windows of opportunity occur during the clinical trajectory of cancer patients. Also, the use of specific nutrients, namely omega-3 fatty acids, may enhance the efficacy of nutritional support when tumor-driven inflammatory response is high...

PURPOSE OF REVIEW: Physical and cognitive frailty are interrelated and synergistic syndromes more frequently seen in old age, which represent intermediate stages between aging successfully and disability. Poor nutrition is a fundamental determinant for both conditions, while various dietary components are proposed to prevent and/or improve them. This updated review discusses the possible influence of nutritional factors on cognitive frailty and its potential mediators. RECENT FINDINGS: Oxidative stress, low-grade systemic inflammation, neuroinflammation, and altered autophagy, all associated with obesity, metabolic syndrome and insulin resistance, are proposed mechanisms to explain the influence of nutrition on cognitive health...

For individuals at risk for type 2 diabetes mellitus or the metabolic syndrome, adherence to an idealized dietary pattern can drastically alter the risk and course of these chronic conditions. Target levels of carbohydrate intake should approximate 30% of consumed calories. Healthy food choices should include copious fruits, vegetables, and nuts while minimizing foods with high glycemic indices, especially processed foods.

Cardiovascular disease (CVD) due to atherosclerosis is the main cause of death in both the elderly and patients with metabolic diseases, including diabetes. Aging processes contribute to the pathogenesis of atherosclerosis. Calorie restriction (CR) is recognized as a dietary intervention for promoting longevity and delaying age-related diseases, including atherosclerosis. Sirt1, an NAD(+)-dependent deacetylase, is considered an anti-aging molecule and is induced during CR. Sirt1 deacetylates target proteins and is linked to cellular metabolism, the redox state and survival pathways...

Creating a negative energy balance by decreasing caloric consumption and increasing physical activity is a common strategy used to treat obesity. A large number of review and original research papers have considered the role of physical activity in weight loss and maintenance. However, their conclusions are at times conflicting. In this review, we have critically evaluated the findings of systematic reviews and meta-analyses and supplemented their conclusions with recently published, high-quality clinical trials...

Obesity increases the risk of a number of chronic diseases in humans including several cancers. Biological mechanisms responsible for such increased risks are not well understood at present. Increases in systemic inflammation and oxidative stress, endogenous production of mutagenic metabolites, altered signaling in proliferative pathways, and increased sensitivity to exogenous mutagens and carcinogens are some of the potential contributing factors. We hypothesize that obesity creates an endogenously mutagenic environment in addition to increasing the sensitivity to environmental mutagens...

BACKGROUND: It is unclear whether specific gut microbiota is associated with remission of type 2 diabetes (T2D) after distinct types of bariatric surgery. AIMS: The aim of this study is to examine gut microbiota changes after laparoscopic Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG) surgery in obese patients with T2D. METHODS: Whole-metagenome shotgun sequencing of DNA fragments using Illumina HiSeq2000 was obtained from stool samples collected from 14 obese T2D patients pre-operatively (while on very low calorie diet) and 1 year after randomisation to laparoscopic SG (n = 7) or RYGB (n = 7)...

A fracture occurs when the applied load is greater than the bone can withstand. Clinical practice guidelines for the management of osteoporosis include recommendations for exercise; one of the few therapies where the proposed anti-fracture mechanisms that include effects on both bone strength and applied loads, where applied loads can come in the form of a fall, externally applied loads, body weight, or muscle forces. The aim of this review is to provide an overview of the clinical evidence pertaining to the potential efficacy of exercise for preventing fractures in older adults, including its direct effects on outcomes along the causal pathway to fractures (e...

Enteral nutrition (EN) support has proven to be a nutrition intervention that can provide full or partial calories to promote growth and development in infants and children. To supply these nutrients, an enteral access device is required, and the use of these devices is growing. Placement of the proper device for the patient need, along with appropriate care and monitoring, is required for individualized patient management. When complications arise, early identification and management can prevent more serious morbidity...

BACKGROUND: Intermittent fasting (IF) is an increasingly popular dietary approach used for weight loss and overall health. While there is an increasing body of evidence demonstrating beneficial effects of IF on blood lipids and other health outcomes in the overweight and obese, limited data are available about the effect of IF in athletes. Thus, the present study sought to investigate the effects of a modified IF protocol (i.e. time-restricted feeding) during resistance training in healthy resistance-trained males...

Secular changes in stature, weight, or other components of the body that can be obtained from historical records have been extensively studied. Cranial change has been central to anthropology for more than a century, but the focus has normally been on change measured in centuries or millennia. Cranial change measured in decades, normally considered to result from plastic response to the environment, has been less studied. This article reports on change in cranial vault dimensions in white Americans. Variables were glabello-occipital length (GOL), basion-bregma height (BBH), basion-nasion length (BNL), maximum cranial breadth (XCB), and biauricular breadth (AUB)...

A comprehensive description of starch biosynthesis and granule assembly remains undefined despite the central nature of starch as an energy storage molecule in plants and as a fundamental calorie source for many animals. Multiple theories regarding the starch synthase (SS)-catalyzed assembly of (α1-4)-linked D-glucose molecules into maltodextrins generally agree that elongation occurs at the non-reducing terminus based on the degradation of radiolabeled maltodextrins though recent reports challenge this hypothesis...

INTRODUCTION: Weight loss interventions such as Roux-en-Y gastric bypass (RYGB) and very low calorie diets (VLCD) lead to improvement of glucose metabolism in obese individuals with type-2 diabetes. Weight loss can also positively influence the unfavorable inflammatory profile associated with obesity. However, a direct comparison of the effect of VLCD and RYGB on systemic inflammation is lacking. METHODS: Systemic inflammation was investigated in age- and BMI-matched morbidly obese T2DM women by determining the number and activation- or memory status of peripheral blood leukocytes by flow cytometry, in addition to measuring circulating levels of cytokines and CRP...

This review discusses two distinct, yet related, mechanisms of sodium-glucose cotransporter 2 (SGLT2) inhibition: Calorie restriction mimicry (CRM) and pro-ketogenic effect, which may explain their cardiovascular benefits. We term these adaptive CRM and pro-ketogenic effects of SGLT2 inhibition, the Robin Hood hypothesis. In English history, Robin Hood was a "good person," who stole from the rich and helped the poor. He supported redistribution of resources as he deemed fit for the common good. In a similar fashion, SGLT2 inhibition provides respite to the overloaded glucose metabolism while utilizing lipid stores for energy production...

 The present study was conducted to establish pharmaceutical intervention guidelines to enable hospital pharmacists to provide optimal pharmacotherapy to cancer patients. Many patients who use oral anticancer agents showed favorable drug compliance but insufficient drug adherence. It was demonstrated that in order to improve drug adherence, it is important to conduct interventions tailored to the patients' conditions so as to encourage interest in their medications, as well as to gain their understanding on the necessity and the side effects of their medications...

It was evaluated the properties of the xanthene dyes Erythrosin B, Eosin Y and theirs Methyl, Butyl and Decyl ester derivatives as possible photosensitizers (PS) for photodynamic treatments. The more hydrophobic dyes self-aggregate in water/ethanol solutions above 70% water (v/v) in the mixture. In buffered water these PS were encapsulated in Pluronic polymeric surfactants of P-123 and F-127 by two methodologies: direct addition and the thin-film solid dispersion methods. The thin solid method provided formulations with higher stabilities besides effective encapsulation of the PS as monomers...
