BACKGROUND/OBJECTIVES: Spendthrift vs. thrifty individuals expend more energy and experience greater weight loss during caloric restriction (CR). Adaptive mechanisms in skeletal muscle, adipose tissue, and on hormone level modulate energy expenditure (EE) during weight loss. Metabolic mechanisms underlying the variability in EE during CR are unclear. The present study explored whether during long-term CR (i) gene expression changes in skeletal muscle and adipose tissue relate with the individual EE response and weight loss, and (ii) altered catecholamine and FGF21-concentrations are associated with measures of metabolic adaptation...

Introduction: Labyrinthine infarction is a cause of acute audiovestibulopathy, but can be diagnosed only in association with other infarctions involving the brainstem or cerebellar areas supplied by the anterior inferior cerebellar artery (AICA) since current imaging techniques cannot visualize an infarction confined to the labyrinth. This case series aimed to establish embolic labyrinthine infarction as a mechanism of isolated acute audiovestibulopathy. Methods: We analyzed clinical features, imaging findings, and mechanisms of embolism in 10 patients (8 men, age range: 38-76) who had developed acute audiovestibulopathy in association with an obvious source of embolism and concurrent acute embolic infarctions in the non-anterior inferior cerebellar artery territories...

This article reports caloric value changes, stability and rheological properties of mayonnaises affected by fat mimetic based on Microparticulated whey protein (MWP) and high-methoxy pectin. Lipid was partially substituted at different levels of 20%, 40%, 60%, 80% and 100%, and the samples were referred to as FM20, FM40, FM60, FM80 and FFM, respectively. The full fat (FF) mayonnaise was used as a control experiment. For rheological properties, the addition of fat mimetic resulted in the gradual decrease of pseudoplastic behavior, relative thixotropic area and viscosity index, while elasticity index exhibited the opposite trend...

Cellulose nanofibril (CNF)-based materials are increasingly used in industrial and commercial applications. However, the impacts of CNF on aquatic life are poorly understood, and there are concerns regarding their potential toxicity. Using a combination of standard ecotoxicological tests and feeding experiments, we assessed the effects of CNF exposure (0.206-20.6 mg/L) on the feeding (food uptake and gut residence time) and life-history traits (growth and reproduction) in the cladoceran Daphnia magna. No mortality was observed in a 48 h acute exposure at 2060 mg/L...

Protein restriction during the suckling phase can malprogram rat offspring to a lean phenotype associated with metabolic dysfunctions later in life. We tested whether protein-caloric restriction during lactation can exacerbate the effect of a high-fat (HF) diet at adulthood. To test this hypothesis, we fed lactating Wistar dams with a low-protein (LP; 4% protein) diet during the first 2 weeks of lactation or a normal-protein (NP; 23% protein) diet throughout lactation. Rat offspring from NP and LP mothers received a normal-protein diet until 60 days old...

Host features, such as cell proliferation rates, caloric intake, metabolism and energetic conditions, significantly influence tumor growth; at the same time, tumor growth may have a dramatic impact on the host conditions. For example, in clinics, at certain stages of the tumor growth, cachexia (body weight reduction) may become so relevant to be considered as responsible for around 20% of cancer deaths. Unfortunately, anticancer therapies may also contribute to the development of cachexia due to reduced food intake (anorexia), commonly observed during the treatment periods...

It is widely accepted that middle ear pathology can cause dizziness and imbalance, however this has been a challenging area to investigate, as the bi-thermal caloric test is difficult to interpret in this cohort. Recently vestibular tests that bypass the middle ear have been developed. These are the Video Head Impulse Test (vHIT) and the Bone Conduction Vestibular Evoked Myogenic Potentials (BC-VEMPs). We have successfully carried out pre-operative vHIT and BC-VEMPs on 20 patients awaiting surgery for middle ear pathologies and have shown that complete testing can be done in less than 30 minutes...

Multivisceral transplantation is the treatment for multiple abdominal organ failure. The patient experiences reduced food intake and absorption of nutrients, contributing to weight loss and decreased muscle mass, reducing functional capacity. A physical and nutritional rehabilitation program based on adequate caloric intake associated with supervised physical exercise seems to support a gain of muscle mass, re-establishing its capacity and functional independence. A rehabilitation program was carried out, consisting of low-intensity aerobic exercise on treadmill, exercises of global strengthening (50% of 1 maximum repetition [1RM], with progressive increase), and nutritional monitoring (oral hypercaloric diet, hyperproteic supplementation daily and after exercise)...

A 21 year old female had recurrent presentations to the Emergency Department (ED) with myalgia, vomiting, abdominal pain and subsequently developed generalized seizures. She was volume depleted with a plasma sodium of 125 mmol/L (reference interval 135-145) and she had fluctuating hypertension. Acute porphyria was suspected and confirmed with raised urine porphobilinogen (PBG)/creatinine ratio of 12·4 umol/mmol (reference interval < 1·5) and she was treated with intravenous haem arginate. Urinary porphyrin/creatinine ratio was 673 nmol/mmol, (reference interval <35) and faecal porphyrins 2430 umol/kg dry weight (reference interval <200) were markedly elevated, with raised faecal CIII:CI ratio, consistent with acute coproporphyria...
