Low fat mass is associated with an increased risk of fracture because of low bone mineral density (BMD) and altered bone micro-architecture. Conversely, overweight and obese patients also have an increased risk of fracture, particularly of the humerus and ankle, despite greater BMD. Visceral abdominal fat, which is the most metabolically active, may be associated with poorer quality of bone tissue properties, as suggested in diabetes. Other factors may contribute to higher fracture risk in overweight patients, notably higher frequency of falls and lower bioavailability of vitamin D stoked in fat...

BACKGROUND: Cardiovascular diseases (CVDs) are the first leading cause of death worldwide. In Saudi Arabia, CVDs are the major killers with a mortality rate of 46%. CVD risk factors are not exclusive to old populations. Thus, the purpose of this study was to approximately find the prevalence of these risk factors, particularly high blood pressure (HBP), high blood glucose (HBG), obesity, and smoking. METHODS: This cross-sectional was conducted in May 2016 and took place in the Ambulatory Care Center of King Abdulaziz Medical City, Jeddah...

The discovery of the obese gene and the demonstration that its encoded protein leptin can reverse obesity due to genetic deficiency of the hormone were landmark discoveries in endocrinology and metabolism. Regarding leptin's role in physiology, it is now established that falling leptin levels are a key signal of the starved state in mice and humans. Repleting leptin reverses the starvation signal both in physiologic starvation and in obesity resulting from genetic leptin deficiency. Since its discovery, it has also been hypothesized that rising leptin levels caused by overfeeding provide a physiologic signal that orchestrates resistance to obesity...

Onychomycosis accounts for 50% of all nail disease cases and is commonly caused by dermatophytes. Diabetes, human immunodeficiency virus, immunosuppression, obesity, smoking, and advancing age are predisposing factors of this fungal infection. Potassium hydroxide and culture are considered the current standard for diagnosing onychomycosis, revealing both fungal viability and species identification. Other diagnostic tests currently available include periodic acid-Schiff staining, polymerase chain reaction techniques, and fluorescent staining...

Previous studies have described the mechanism of ankle fractures, their seasonal variation, and fracture patterns but never in conjunction. In addition, the cohorts previously studied were either not from trauma centers or were often dominated by low-energy mechanisms. The present study aimed to describe the epidemiology of ankle fractures presenting to an urban level 1 trauma center. The records from an urban level 1 trauma center located in the Midwestern United States were retrospectively reviewed, and the injury mechanism and energy, time of injury, day of week, month, and patient characteristics (age, gender, comorbidities, smoking status) were collected...

OBJECTIVE: Modification of sleep behaviors in teenagers has been observed over the past 30years with a reduction in overall sleep time and an increasing number of teenagers suffering from sleep deprivation. Sleep deprivation is linked to physical problems such as obesity but also to change in performance at school and mood disorders. Changes have been associated with the use of screens, cell phones, Internet and social media. Use of screens has been shown to delay sleep onset and melatonin secretion and stimulation of wake systems by interaction with social media may exacerbate these effects...

BACKGROUND: Gait Initiation (GI) is a functional task representing one of the first voluntary destabilizing behaviours observed in the development of a locomotor pattern as the whole body centre of mass transitions from a large to a small base of support. Conversely, Gait Termination (GT) consists in the transition from walking to standing which, in everyday life, is a very common movement. Compared to normal walking, it requires higher control of postural stability. For a safe GT, the forward movement of the body has to be slowed down to achieve a stable upright position...

What is the central question of this study? Non-invasive muscle function tests have not been validated for use in the study of muscle performance in high-fat-fed mice. What is the main finding and its importance? This study shows that grip strength, hang wire and four-limb hanging tests are able to discriminate the muscle performance between chow-fed and high-fat-fed mice at different time points, with grip strength being reliable after 5, 10 and 20 weeks of dietary intervention. Non-invasive tests are commonly used for assessing muscle function in animal models...

Sleep affects physical growth, behavior and emotional development besides determining cognitive functioning, learning and attention especially of a growing child. Adolescence represents one of the critical transitions in the life span and is characterized by a tremendous pace in growth and change that is second only to that of infancy. Adolescent sleep patterns deserve particular attention because of the potential impact on school performance. Average sleep period in adolescents is reduced during school days to around seven hours...

People who are overweight or have obesity are estimated to comprise 30% of the global population and up to 59% of companion dogs and cats are estimated to be above their optimal body weight. The prevalence of human and companion obesity is increasing. The direct and indirect costs of obesity and associated comorbidities are significant for human and veterinary healthcare. There are numerous similarities between obesity in people and companion animals, likely related to the shared environmental and lifestyle elements of this multifactorial disease...

This study examined the effects of controlled whole-body vibration training on reducing risk of slip-related falls in people with obesity. Twenty-three young adults with obesity were randomly assigned into either the vibration or placebo group. The vibration and placebo groups respectively received 6-week vibration and placebo training on a side-alternating vibration platform. Before and after the training, the isometric knee extensors strength capacity was measured for the two groups. Both groups were also exposed to a standardized slip induced by a treadmill during gait prior to and following the training...
