Frailty is a geriatric syndrome that is an important public health problem for the older adults living in the USA. Although several methods have been developed to measure frailty in humans, we have very little understanding of its etiology. Because the molecular basis of frailty is poorly understood, mouse models would be of great value in determining which pathways contribute to the development of frailty. More importantly, mouse models would be critical in testing potential therapies to treat and possibly prevent frailty...

BACKGROUND: Family interventions appear to be effective at treating young people's substance misuse. However, implementation of family approaches in UK services is low. This study aimed to demonstrate the feasibility of recruiting young people to an intervention based on an adaptation of adult social behaviour and network therapy. It also sought to involve young people with experience of using substance misuse services in the research process. OBJECTIVES: To demonstrate the feasibility of recruiting young people to family and social network therapy and to explore ways in which young people with experience of using substance misuse services could be involved in a study of this nature...

A 49-year-old woman with a past history of several infundibular cysts in the head and neck region presented with a 6-month history of a nonhealing perianal abscess on a background of 13 years of chronic sacral-buttock abscesses and discharging sinuses as part of hidradenitis suppurativa. After 2 surgical procedures and inadequate healing, a wide local excision was performed. The surgical specimen revealed an extensive, infiltrating, cystic and deeply penetrating, dermal and subcutaneous neoplasm with multiple fistulous tracts extending to the skin surface...

PURPOSE: Waste products of metabolism accumulate in patients with chronic kidney disease, and require clearance by haemodialysis (HD). We wished to determine whether there was an association between resting energy expenditure (REE) and total energy expenditure (TEE) in HD patients and body composition. SUBJECTS/METHODS: We determined REE by recently validated equations (CKD equation) and compared REE with that estimated by standard equations for REE, and TEE calculated from patient reported physical activity, in HD patients with corresponding body composition measured by dual energy X-ray absorptiometry (DEXA) scanning...

Patients frequently leave hospital uninformed about the details of their hospital stay with studies showing that only 59.9% of patients are able to accurately state their diagnosis and ongoing management after discharge. 1 2 This places patients at a higher risk of complications. Educating patients by providing them with accurate and understandable information enables them to take greater control, potentially reducing readmission rates, and unplanned visits to secondary services whilst providing safer care and improving patient satisfaction...

Guido Alessandri, Antonio Zuffianò, Enrico Perinelli
A common situation in the evaluation of intervention programs is the researcher's possibility to rely on two waves of data only (i.e., pretest and posttest), which profoundly impacts on his/her choice about the possible statistical analyses to be conducted. Indeed, the evaluation of intervention programs based on a pretest-posttest design has been usually carried out by using classic statistical tests, such as family-wise ANOVA analyses, which are strongly limited by exclusively analyzing the intervention effects at the group level...

Rationale: Non-classical mouse monocyte (CX3CR1(high), Ly-6C(low)) patrolling along the vessels of the microcirculation is critical for endothelial homeostasis and inflammation. Due to technical challenges it is currently not established how patrolling occurs in large arteries. Objective: This study was undertaken to elucidate the molecular, migratory and functional phenotype of patrolling monocytes in the high shear and pulsatile environment of large arteries in healthy, hyperlipidemic and atherosclerotic conditions...

BACKGROUND: Carbohydrate is accepted as the principal nutrient affecting blood glucose in diabetes; however, current guidelines are unable to specify the optimal quantity of carbohydrate for glycaemic control. No studies exist that describe current practice amongst healthcare professionals giving carbohydrate advice in type 2 diabetes. The present study aims to improve understanding of the degree of variation in the current practice of UK registered dietitians (RDs) by describing how RDs advise patients...

BACKGROUND & AIMS: Waste products of metabolism accumulate in patients with kidney failure and it has been proposed that the amount of dialysis treatment patients require be adjusted for energy expenditure. This requires validation of methods to estimate energy expenditure in dialysis patients. METHODS: We compared values of resting energy expenditure (REE) estimated in peritoneal dialysis (PD) patients using a selection of available equations with estimates derived using a novel equation recently validated in chronic kidney disease patients (CKD equation)...

Long-term prospective studies of the outcomes associated with HCV infection are rare and critical for assessing the potential impact of HCV treatment. Using liver biopsy as a start point, we looked at development of end stage liver disease (ESLD), hepatocellular carcinoma (HCC) and liver-related death (LRD) according to fibrosis stage, among a cohort of American Indian/Alaska Native persons in Alaska. Persons were classified as having no/mild (Ishak=0,1), moderate (Ishak=2), or severe (Ishak=3,4) fibrosis or cirrhosis (Ishak=5,6)...

Iron (Fe) metabolism is modified by many nutritional factors. Amino acids (AA) play a central role in various biological processes, such as protein synthesis and energy supply. However, the influence of AA status on iron metabolism has not been investigated. Here, we test whether AA alters iron metabolism in an intestinal cell model. Both Fe uptake and transfer across the cell monolayer were significantly increased by non-essential AA deficiency (both p<0.001) while only Fe transfer was increased by essential AA deficiency (p<0...

CONTEXT: Sulfate is critical in the biotransformation of multiple compounds via sulfation. These compounds include neurotransmitters, proteoglycans, xenobiotics, and hormones such as dehydroepiandrosterone (DHEA). Sulfation reactions are thought to be rate-limited by endogenous sulfate concentrations. The gene, SLC13A1, encodes the sodium-sulfate cotransporter NaS1, responsible for sulfate (re)absorption in the intestines and kidneys. We previously reported two rare, non-linked, nonsense variants in SLC13A1 (R12X and W48X) associated with hyposulfatemia (P = 9 × 10(- 20))...

Burns caused by exhaust systems in children may be associated with considerable morbidity. Current epidemiological data varies, but no data are available for the UK population. We aim to identify the pattern of exhaust-related burns affecting children who presented to a regional centre for paediatric burn care in the UK. Patients who sustained burns related to exhaust mechanisms between May 2005 and August 2012 were identified via the departmental database. Data collected included patient demographics, burn injury information, management and outcomes...

An increasing number of genome-wide association (GWA) studies are now using the higher resolution 1000 Genomes Project reference panel (1000G) for imputation, with the expectation that 1000G imputation will lead to the discovery of additional associated loci when compared to HapMap imputation. In order to assess the improvement of 1000G over HapMap imputation in identifying associated loci, we compared the results of GWA studies of circulating fibrinogen based on the two reference panels. Using both HapMap and 1000G imputation we performed a meta-analysis of 22 studies comprising the same 91,953 individuals...
