General anesthesia increases the risk for cognitive impairment post operation, especially in the elderly and vulnerable individuals. Recent animal studies on the impact of anesthesia on postoperative cognitive impairment have provided some valuable insights, but much remains to be understood. Here, by using mice of various ages and conditions, we found that anesthesia with propofol and sevoflurane caused significant deficits in spatial learning and memory, as tested using Morris Water Maze (MWM) 2-6 days after anesthesia exposure, in aged (17-18 months old) wild-type (WT) mice and in adult (7-8 months old) 3xTg-AD mice (a triple transgenic mouse model of Alzheimer's disease (AD)), but not in adult WT mice...

Alzheimer's disease (AD) is a neurodegenerative disorder of the elderly. As the prevalence of AD rises in the 21st century, there is an urgent need for the development of effective pharmacotherapies. Currently, drug treatments target the symptoms of the disease and do not modify or halt the disease progress. Thus, natural compounds have been investigated for their ability to treat AD. This review examines the efficacy of curcumin, a polyphenol derived from turmeric herb, to treat AD. We summarize the in vivo and in vitro research describing the mechanisms of action in which curcumin modifies AD pathology: curcumin inhibits the formation and promotes the disaggregation of amyloid-β plaques, attenuates the hyperphosphorylation of tau and enhances its clearance, binds copper, lowers cholesterol, modifies microglial activity, inhibits acetylcholinesterase, mediates the insulin signaling pathway, and is an antioxidant...

BACKGROUND: Loss of muscle mass was reported to be associated with metabolic syndrome (MetS), but little is known about the gender difference. Thus, the aim of this study was to evaluate the relationship between lower muscle mass and MetS and determine whether there was any gender difference or not. METHODS: A total of 394 middle-aged and elderly Taiwanese adults (138 males and 256 females) were enrolled and completed our health survey. They were stratified into three groups according to appendicular skeletal muscle mass divided by weight...

AIM: Accelerated thrombin action is associated with insulin resistance. It is known that upon activation by binding to dermatan sulfate proteoglycans, heparin cofactor Ⅱ(HCⅡ) inactivates thrombin in tissues. Because HCⅡ may be involved in glucose metabolism, we investigated the relationship between plasma HCⅡ activity and insulin resistance. METHODS AND RESULTS: In a clinical study, statistical analysis was performed to examine the relationships between plasma HCⅡ activity, glycosylated hemoglobin (HbA1c), fasting plasma glucose (FPG), and homeostasis model assessment-insulin resistance (HOMA-IR) in elderly Japanese individuals with lifestyle-related diseases...

AIMS/INTRODUCTION: The incidence of type 2 diabetes is higher in elderly patients, in whom this disease is associated with dementia, falling, stroke and death. We utilized a continuous glucose monitoring device to analyze the relationship between hypoglycemia and diabetes treatments to identify risk factors for hypoglycemia (defined as a blood glucose level <70 mg/dL). MATERIALS AND METHODS: We classified 170 patients aged ≥65 years with type 2 diabetes who were receiving steady-state medication (29 of whom were inpatients) into hypoglycemic and non-hypoglycemic groups, and compared their glycosylated hemoglobin levels, treatment types, continuous glucose monitoring data and other parameters...

BACKGROUND: Fatty infiltration in skeletal muscle is directly linked to loss of muscle strength and is associated with various adverse physical outcomes such as muscle atrophy, inflammation, insulin resistance, mobility impairments, and even mortality in the elderly. Aging, mechanical unloading, muscle injury, and hormonal imbalance are main causes of muscle fat accumulation, and the fat cells are derived from muscle stem cells via adipogenic differentiation. However, the pathogenesis and molecular mechanisms of fatty infiltration in muscles are still not fully defined...

Diabetic ketoacidosis (DKA) and hyperglycemic hyperosmolar state (HHS) are the most serious and life-threatening hyperglycemic emergencies in diabetes. DKA is more common in young people with type 1 diabetes and HHS in adult and elderly patients with type 2 diabetes. Features of the 2 disorders with ketoacidosis and hyperosmolality may coexist. Both are characterized by insulinopenia and severe hyperglycemia. Early diagnosis and management are paramount. Treatment is aggressive rehydration, insulin therapy, electrolyte replacement, and treatment of underlying precipitating events...

Age is one of the main risk factor for the presence of obstructive sleep apnea (OSA). This syndrome is associated with hypertension, cardiovascular disease, cognitive impairment and metabolic abnormalities, such as type 2 diabetes. Continuous positive airway pressure (CPAP) represents the gold standard therapy, but its benefit is still to be determined in very elderly. We report the blood pressure and metabolic changes in a very elderly obese with severe OSA after 3-month CPAP therapy. We have evaluated a very elderly obese male affected by severe symptomatic OSA, poor controlled nocturnal hypertension and insulin resistance...

Metabolic syndrome (MS), a cluster of metabolic abnormalities linked to insulin-resistance and abdominal obesity, is associated with an increased risk of Type II diabetes mellitus (DM) and cardiovascular (CV) disease. Its prevalence is high, affecting 20%-30% of the general population, and increases with age in a sex-specific manner: in fact, while below 50 years it is slightly higher in men, it reverses after 50 years. The pronounced age-related increase in the prevalence of MS in women occurs as the result of several factors, which may be classified into sex- and gender-related factors...

Clinical and experimental studies show that aging exacerbates hypertension-induced cerebral microhemorrhages (CMHs), which progressively impair neuronal function. There is growing evidence that aging promotes insulin-like growth factor 1 (IGF-1) deficiency, which compromises multiple aspects of cerebromicrovascular and brain health. To determine the role of IGF-1 deficiency in the pathogenesis of CMHs, we induced hypertension in mice with liver-specific knockdown of IGF-1 (Igf1(f/f)  + TBG-Cre-AAV8) and control mice by angiotensin II plus l-NAME treatment...

OBJECTIVE: Benign prostatic hyperplasia (BPH) is the most common proliferative abnormality of the prostate affecting elderly men throughout the world. Epidemiologic studies have shown that diabetes significantly increases the risk of developing BPH, although whether anti-diabetic medications preventing the development of BPH remains to be defined. We have previously found that stromally expressed insulin-like growth factor 1 (IGF-1) promotes benign prostatic epithelial cell proliferation through paracrine mechanisms...

Skeletal muscle abnormalities are responsible for significant disability in the elderly. Sarcopenia is the main alteration occurring during senescence and a key public health issue as it predicts frailty, poor quality of life, and mortality. Several factors such as reduced physical activity, hormonal changes, insulin resistance, genetic susceptibility, appetite loss, and nutritional deficiencies are involved in the physiopathology of muscle changes. Sarcopenia is characterized by structural, biochemical, molecular and functional muscle changes...

Alzheimer's disease (AD) is a severe, chronic and progressive neurodegenerative disease associated with memory and cognition impairment ultimately leading to death. It is the commonest reason of dementia in elderly populations mostly affecting beyond the age of 65. The pathogenesis is indicated by accumulation of the amyloid-beta (Aβ) plaques and neurofibrillary tangles (NFT) in brain tissues and hyperphosphorylation of tau protein in neurons. The main cause is considered to be the formation of reactive oxygen species (ROS) due to oxidative stress...

Alzheimer's disease (AD) is the most common cause of dementia in the elderly. Pharmacological treatment of AD includes Anticholinesterase Inhibitors (AChEIs) for mild-moderate AD, and memantine for severe AD. These drugs provide mainly symptomatic short-term benefits without clearly influencing the progression of the disease. Pioglitazone (AD4833) is an insulin sensitizer of the thiazolidinedione class of nuclear Peroxisome-Proliferator Activated Receptor γ (PPARγ) agonists. It binds to PPARγ, affecting gene transcription and reducing inflammation...
