Antibiotic resistance is an increasing threat to public health globally. Indicators on antibiotic prescribing are required to guide antibiotic stewardship interventions in nursing homes. However, such indicators are not available in the literature. Our main objective was to provide a set of quantity metrics and proxy indicators to estimate the volume and appropriateness of antibiotic use in nursing homes.

Recently published articles were first used to select quantity metrics and proxy indicators, that were adapted to the French nursing home context. A cross-sectional observational study was then conducted based on reimbursement databases. We included all community-based nursing homes of the Lorraine region in north-eastern France. We presented descriptive statistics for quantity metrics and proxy indicators. For proxy indicators, we also assessed performance scores, clinimetric properties (measurability, applicability, and room for improvement), and conducted case-mix and cluster analyses.

209 nursing homes were included. We selected fifteen quantity metrics and eleven proxy indicators of antibiotic use. The volume of antibiotic use varied hugely between nursing homes. Proxy indicators' performance scores were low, and variability between nursing homes was high for all indicators, highlighting an important room for improvement. buy SF2312 Six out of the eleven proxy indicators had good clinimetric properties. Three distinct clusters were identified according to the number of proxy indicators for which the acceptable target was reached.

This set of fifteen quantity metrics and eleven proxy indicators may be adapted to other contexts and could be used to guide antibiotic stewardship programmes in nursing homes.

Cell biology and physiology modified this view in the 20st century by defining the constant interplay between bone-forming and bone resorbing cells that take place during bone growth and remodeling, therefore demonstrating that bone is as alive as any other tissues in the body. During the past 40 years human and, most important, mouse genetics, have allowed not only the refinement of this notion by identifying the many genes and regulatory networks responsible for the crosstalk existing between bone cells, but have redefined the role of bone by showing that its influence goes way beyond its own physiology. Among its newly identified functions is the regulation of energy metabolism by 2 bone-derived hormones, osteocalcin and lipocalin-2. Their biology and respective roles in this process are the topic of this review.Xenobiotic metabolizing enzymes and other proteins, including odorant-binding proteins located in the nasal epithelium and mucus, participate in a series of processes modulating the concentration of odorants in the environment of olfactory receptors (ORs) and finely impact odor perception. These enzymes and transporters are thought to participate in odorant degradation or transport. Odorant biotransformation results in 1) changes in the odorant quantity up to their clearance and the termination of signaling and 2) the formation of new odorant stimuli (metabolites). Enzymes, such as cytochrome P450 and glutathione transferases (GSTs), have been proposed to participate in odorant clearance in insects and mammals as odorant metabolizing enzymes. This study aims to explore the function of GSTs in human olfaction. Using immunohistochemical methods, GSTs were found to be localized in human tissues surrounding the olfactory epithelium. Then, the activity of 2 members of the GST family toward odorants was measured using heterologously expressed enzymes. The interactions/reactions with odorants were further characterized using a combination of enzymatic techniques. Furthermore, the structure of the complex between human GSTA1 and the glutathione conjugate of an odorant was determined by X-ray crystallography. Our results strongly suggest the role of human GSTs in the modulation of odorant availability to ORs in the peripheral olfactory process.The purpose of this study was to determine if muscular dimensional changes with increases in torque production are influenced by age- and obesity-related increases in intramuscular fat, and its relationship to percent body fat (%BF), echo intensity (EI), strength, and maximum walking speed. Sixty-six healthy men were categorized into 3 groups based on age and body mass index status (young normal weight [YNW], older normal weight [ONW], and older obese [OB]). Participants underwent %BF assessments, resting ultrasonography to determine muscle size (cross-sectional area [CSA]) and EI of the superficial quadriceps, and a 10-m maximum walking speed assessment. Maximal and submaximal (rest-100% MVC in 10% increments) isometric leg extension strength was assessed while changes in rectus femoris (RF) CSA, width, and depth were obtained with ultrasonography. Echo intensity and %BF were different among all groups (p ≤ .007), with the YNW and OB groups exhibiting the lowest and highest %BF and EI values, respectively. The RF increased in depth and decreased in width with increases in torque intensity for all groups. The ONW group demonstrated no change (-0.08%) in RF CSA across torque intensities, whereas the YNW group (-11.5%) showed the greatest decrease in CSA, and the OB group showed a more subtle decrease (-4.6%). Among older men, a greater change in RF CSA was related to poorer EI (r = -0.355) and higher %BF (r = -0.346), while a greater decrease in RF width was associated with faster walking speeds (r = -0.431). Examining muscular dimensional changes during contraction is a unique model to investigate the influence of muscle composition on functional performance.
Unbiased estimates of the health and economic impact of healthcare-associated infections (HAIs) are scarce and focus largely on patients with bloodstream infection (BSI). We sought to estimate the hospital length of stay (LOS), mortality and costs of HAIs and the differential effect on patients with an antimicrobial resistance (AMR) infection.

A multi-site, retrospective case-cohort of all acute-care hospital admissions with a positive culture of one of the five organisms of interest (Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Staphylococcus aureus or Enterococcus faecium) from January 1, 2012 through December 30, 2016. Data linkage was used to generate a dataset of statewide hospital admissions and pathology data. Patients with bloodstream, urinary or respiratory tract infections were included in the analysis and matched to a sample of uninfected patients. We use multistate survival models to generate LOS and logistic regression to derive mortality estimates.

20,390 cases were matched to 75,635 uninfected control patients.
