Declines in Limb Muscle Mass Correlate with Higher Mortality in Late Life

Given that resistance training is shown to reduce mortality in older individuals, it makes sense that we would see the opposite effect when looking at low muscle mass in limbs. Skeletal muscle isn't an inert tissue, being quite involved in insulin metabolism, for example, and exercise has all sorts of interesting effects on the operation of metabolism, such as upregulation of beneficial cellular stress response mechanisms. Aging is associated with a progressive loss of muscle mass and strength, with the loss of stem cell activity being a leading cause. This ultimately results in frailty and the condition of weakness known as sarcopenia. In our modern societies of sedentary convenience, this loss is much faster that it would otherwise be if people were more active, and hence the point that resistance training improves matters from the present baseline. That is only the case because most older people do not undertake any sort of effort to maintain muscle mass and strength. Evaluating body composition, especially appendicular muscle mass, can be an effective strategy for predicting longevity in people over 65 years of age, according to a new study. The appendicular muscles are the muscles that move the appendages or extremities - the arms and legs. They also play a key role in stabilizing the shoulders and hips. The researchers studied a group of 839 men and women over the age of 65 for approximately four years. They observed that all-cause mortality risk increased near...

AbstractPurpose of reviewIn this review article, we evaluate sex differences in the natural history of NAFLD and highlight distinct risk profiles of women with NAFLD, as well as unique treatment considerations and research gaps.Summary of FindingsReproductive factors, such as menopausal status, should be considered when evaluating NAFLD risk in women, as well as additional reproductive risk factors such as age at menarche, presence of polycystic ovary syndrome, and gestational diabetes. Women do appear to have lower risk for hepatocellular carcinoma from NASH, as well as lower mortality from NASH cirrhosis than men, althou...

Authors: Lega IC, Lipscombe LL Abstract Obesity and diabetes have both been associated with an increased risk of cancer. In the face of increasing obesity and diabetes rates worldwide, this is a worrying trend for cancer rates. Factors such as hyperinsulinemia, chronic inflammation, anti-hyperglycemic medications and shared risk factors have all been identified as potential mechanisms underlying the relationship. The most common obesity- and diabetes-related cancers are endometrial, colorectal and post menopausal breast cancers. In this review, we summarize the existing evidence that describes the complex relations...

Abstract Cardiovascular diseases are become the primary cause of death in women. The cardiovascular risk of the woman has unknown specificities and remains underestimated. At equal age, women have more cardio vascular risk factors than men. All these specificities must be taken into account for an optimized evaluation of cardiovascular risk and for improvement of CV management in women. Some traditional risk factors are more deleterious in women such as hypertension, tobacco, diabetes or psycho-social stress and they are less well controlled compared to men. Women are also exposed to hormonal risk factors (contrac...

ConclusionsA history of MST is common among older women veterans and associated with a range of medical and mental health diagnoses. These findings call attention to the need for additional research in this understudied population, and the importance of trauma-informed care approaches for women across the lifespan.

Purpose of review To delineate the current state of evidence on the impact of night shift work on age at natural menopause. Recent findings The only direct evidence is from a single observational study, which indicates that women who work night shifts are at moderately higher risk for earlier menopause and that this risk is more pronounced among younger women. Underlying biological mechanisms have yet to be sufficiently substantiated. A long-held line of inquiry, most strongly propagated by the observed link between night shift work and female breast cancer, is the ‘Light at Night’ hypothesis, which sugges...

Conclusions: Early menarche increases the risk of T2DM, whereas later menarche decreases the risk. The association seems to be partially mediated by BMI.

Objective: A first-degree family history of diabetes (FHD) contributes to increased risks of metabolic and cardiovascular diseases. Bone is an insulin-resistant site and an organ susceptible to microvascular complications. The goal of the present study was to investigate the association of FHD with bone mineral density (BMD) in postmenopausal women. Methods: In all, 892 normoglycemic postmenopausal women were divided into subgroups of participants with or without a first-degree FHD. BMD was measured using dual-energy x-ray absorptiometry. Fasting plasma insulin and glucose levels were measured, and insulin resistance ...

Conclusions: T2DM status moderated the relationship between blood adiponectin and ALMBMI, where blood adiponectin was positively associated with ALMBMI in postmenopausal women without T2DM, but not those with T2DM. Dysregulated metabolism in T2DM may contribute to lower muscle mass in women with T2DM, but future research is required to elucidate this mechanistic link. The negative association between blood leptin and ALMBMI was a novel finding. Future studies will need to more clearly define the relationship between these variables.

ConclusionHigher staging and histology grades in patients with endometrial cancers are associated with reduced GFR. Patients with mild-to-moderate CKD had significantly higher number of cancers with higher histology grades and higher stages than patients with mild or normal GFR category. Decline in GFR was independently associated with more aggressive cancers without other well-known risk factors for endometrial cancer development like age, menopause, diabetes, and obesity.
