Menopause and Hot Flashes. Menopause is a natural change that occurs in a woman’s life when her ovaries stop producing estrogen and progesterone. Typically, this happens between the ages of… Continue reading Novel Drug for Hot Flashes
The impact of RSV infection. The respiratory syncytial virus (RSV) is a highly contagious virus that can cause serious illness in infants and young children, as well as adults 65… Continue reading The first RSV vaccine for adults ≥60
American College of Physician (ACP) committee conducted a systematic review of 38 randomized controlled clinical trials focusing on testosterone supplementation in individuals with age-related hypogonadism. The study participants had an… Continue reading Testosterone Supplementation
A group of 2,000 women with osteopenia receiving either zoledronate infusion or placebo were followed for 6 years. Zoledronate 5 mg or placebo was provided every 1.5 years. At the end of the study, the intravenous bisphosphonate reduced vertebral and nonvertebral fractions significantly by about 55% and 35% respectively.
Findings are of major significance as bisphosphonates in general and zoledronate specifically have been approved only for osteoporosis and not osteopenia. Would this expand indications for zoledronate? Should patients with osteopenia be treated?
The Endocrine Society has just released its guidelines on how to manage the elderly with diabetes. Guidelines are overall similar to those of ADA and AACE but with greater emphasis in avoidance of adverse events such; as hypoglycemia, malnutrition, excessive weight loss, frailty, falls, and drug side effects. See below for more details.
About 9,000 adults were randomized to receive tight or less-tight systolic blood pressure control. They were followed for about 5 years for cognition and dementia outcomes.
Although the primary outcome was almost significant, the secondary outcomes were truly significant for improvement of mild cognitive impairment or probable dementia with intensive systolic blood pressure <120 mmHg over those who achieved sBP <140 mmHg.
While further trials are needed to clarify the above findings, there appears to be no harm of lowering the sBP down to <120 mmHg in this study.
Personalized therapy is crucial in good clinical practice, and in the management of older patients with subclinical hypothyroidism, multiple factors must be considered, including age-dependent TSH cutoffs, thyroid autoimmunity, the burden of comorbidities, and the possible presence of frailty.
Levothyroxine is the drug of choice for the treatment of hypothyroid older people, but the risk of overtreatment, potential adverse drug reactions, and patient compliance should always be considered and thyroid status periodically reassessed.
This is an important study evaluating the associative factors and natural history of atrial fibrillation. Until age 90, men are at higher risk of developing A.Fib compared to women. Tall women, and overweight and dyslipidemic men are more likely to experience it than their counterparts. Lifetime risk for Atrial fibrillation high, more than 30%. It increases the mortality rate by 3.5 fold in both genders. Subjects were followed for about 13 years.
The Recommended Daily Allowance (RDA) for protein intake in the adult population is widely promoted as 0.8 grams/kg/day. Aging may increase protein requirements, particularly to maintain muscle mass.
Authors investigated whether controlled protein consumption at the current RDA or twice the RDA (2 x RDA) affects skeletal muscle mass and physical function in elderly men.
Study found that consumption of a diet providing 2 x RDA for protein compared with the current guidelines was found to have beneficial effects on lean body mass and leg power in elderly men.
A structured exercise program was not associated with a decreased risk for frailty among older adults. However, the beneficial effect of the exercise program on reducing major mobility disability was not affected by whether the participants were frail at baseline.
The anorexia of aging, which affects 20% of older adults, has been well documented within the current body of evidence as a primary cause of reduced daily intake in this population. This condition is characterized by reductions in appetite in combination with early satiation and sustained increases in satiety.
Circulating concentrations of the hunger-stimulating hormone ghrelin are lower, whereas the satiety hormones cholecystokinin, peptide YY, and GLP-1 are elevated in older adults compared with their younger counterparts. Gastric emptying also tends to be slower in older adults than in younger adults, which leads to early satiation. These responses occur concomitantly with an increase in perceived fullness and decreased hunger, desire to eat, and prospective food consumption.

Higher fasting insulin levels and increased insulin resistance predict future memory decline as measured by verbal fluency. About 4,000 individuals, average age 50, were followed for 11 years. These findings imply the need of addressing insulin resistance early rather then later, when prediabetes or diabetes emerge.
