In this international study, we examined the incidence of hip fractures, postfracture treatment, and all-cause mortality following hip fractures, based on demographics, geography, and calendar year. We used patient-level healthcare data from 19 countries and regions to identify patients aged 50 years and older hospitalized with a hip fracture from 2005 to 2018. The age- and sex-standardized incidence rates of hip fractures, post-hip fracture treatment (defined as the proportion of patients receiving anti-osteoporosis medication with various mechanisms of action [bisphosphonates, denosumab, raloxifene, strontium ranelate, or teriparatide] following a hip fracture), and the all-cause mortality rates after hip fractures were estimated using a standardized protocol and common data model.

Purpose: The aim was to compare the anthropometric and metabolic profiles and lifestyle behaviours of yogurt consumers and non-consumers and to determine if the observed differences persisted after adjustment for diet quality and related variables.

Methods: Using cross-sectional and follow-up data from the Québec Family Study, men and women were classified into yogurt consumers (n = 269; 96 men and 173 women) and non-consumers (n = 570; 279 men and 291 women), and their anthropometric measurements, metabolic profiles, and lifestyle factors were compared.

Results: Men yogurt consumers had a lower body weight, BMI, % body fat, waist circumference and lower plasma insulin, and C-peptide concentrations in response to oral glucose, while women yogurt consumers had lower waist circumference, BMI, % body fat, plasma glucose, insulin, and C-peptide compared with non-consumers (P < 0.

Recent data support the idea that regular yogurt consumption promotes body weight stability. The simplest explanation is that regular consumption of healthful foods such as yogurt results in decreased intake of less healthful foods containing high amounts of fat and/or sugar. There is also evidence to suggest that the high calcium and protein contents of yogurt and other dairy foods influence appetite and energy intake.

Article Synopsis
  • - The study investigates the relationship between abdominal fat measured by DXA and subcutaneous fat (ScF) and visceral fat (VF) in overweight/obese postmenopausal women before and after weight loss, noting that these measurements often involve expensive CT scans and radiation exposure.
  • - Two groups of 137 women underwent either caloric restriction alone or caloric restriction combined with resistance training, with AF assessed through DXA and CT scans.
  • - Results show strong correlations between AF-DXA and ScF both before and after weight loss, while associations with VF were weaker, suggesting that AF-DXA may still be relevant for ScF but less reliable for VF after weight loss.

This cross-sectional study proposes two relative strength indexes in order to evaluate the risks of lower mobility in healthy older adults: 1) handgrip strength on body mass index and 2) quadriceps strength on body weight. Nine hundred and four men and women aged between 67-84 years old were tested for body composition, muscle strength and mobility function. Individuals in the lowest and middle tertiles of relative handgrip strength were respectively 2.

The corticotropin-releasing factor (CRF) system is involved in numerous physiological and behavioral actions, including the regulation of energy balance. We examined the effects of the CRF(1) receptor antagonist, SSR125543, on energy balance and food deprivation-induced neuronal activation in obese rats. Lean (Fa/?) and obese (fa/fa) Zucker rats were treated orally with SSR125543 at a daily dose of 30 mg/kg for 21 days.

The effects of the cannabinoid-1 receptor (CB(1)) antagonist rimonabant on energy metabolism and fasting-induced hypothalamic-pituitary-adrenal (HPA) axis and neuronal activation were investigated. Lean and obese Zucker rats were treated orally with a daily dose of 10 mg/kg rimonabant for 14 days. A comprehensive energy balance profile based on whole-carcass analyses further demonstrated the potential of CB(1) antagonists for decreasing energy gain through reducing food intake and potentially increasing brown adipose tissue thermogenesis.

The primary stress response involves neuronal activation that ultimately leads to the release of glucocorticoids. Circulating glucocorticoids are thought to influence their own synthesis and release through a negative feedback mechanism that inhibits the activity of the hypothalamic and pituitary components of the stress axis. This study was designed to address the hypothesis that glucocorticoids modify corticotropin-releasing factor (CRF) and neuropeptide Y (NPY) mRNA levels in the rainbow trout (Oncorhynchus mykiss) brain.

The objectives of this study were to characterize rainbow trout (Oncorhynchus mykiss) corticotropin-releasing factor (CRF)-binding protein (CRF-BP) cDNA and to examine the variations in CRF-BP and CRF mRNA levels in response to different intensities of stress. Trout were physically disturbed by a single or three consecutive periods of chasing until exhaustion followed by 2 h of recovery. The pituitary CRF-BP and preoptic area CRF1 mRNA contents were significantly increased only after repeated chasing events.

Corticotropin-releasing factor (CRF)-related peptides are involved in numerous physiological and behavioral actions, including activation of the pituitary-adrenal axis, stimulation of anxiety-related behaviors and modulation of cardiovascular and gastrointestinal functions. They are also capable of strong anorectic and thermogenic effects. In fact, the CRF system, which promotes a negative energy profile upon activation, could represent a potential target for the pharmacological treatment of obesity.
