Sex differences are consistently identified in determining the prevalence, manifestation, and response to therapies in several systemic disorders, including those affecting the cardiovascular (CV), skeletal muscle, and nervous system. Interestingly, such differences are often more noticeable as we age. For example, premenopausal women experience a lower risk of CV disease than men of the same age. While at an advanced age, with menopause, the risk of cardiovascular diseases and adverse outcomes increases exponentially in women, exceeding that of men. However, this effect appears to be reversed in diseases such as pulmonary hypertension, where women are up to seven times more likely than men to develop an idiopathic form of the disease with symptoms developing ten years earlier than their male counterparts. Explaining this is a complex question. However, several factors and mechanisms have been identified in recent decades, including a role for sex hormones, particularly estrogens and their related receptors. Furthermore, an emerging role in these sex differences has also been suggested for β-adrenergic receptors (βARs), which are essential regulators of mammalian physiology. It has in fact been shown that βARs interact with estrogen receptors (ER), providing further demonstration of their involvement in determining sexual differences. Based on these premises, this review article focused on the β3AR subtype, which shows important activities in adipose tissue but with new and interesting roles in regulating the function of cardiomyocytes and vascular cells. In detail, we examined how β3AR and ER signaling are intertwined and whether there would be sex- and age-dependent specific effects of these receptor systems. • In women, estrogen declines with aging and menopause, and most of their cardiovascular benefits are lost. • Estrogens influence β-3 adrenergic receptor (β3AR) activity in cells of the cardiovascular and non-cardiovascular systems. • β3AR may account for estrogen-mediated effects within the cardiovascular system.

We evaluated the short-term effects of a flavanol-rich cocoa (FRC) on lipid profile and selected oxidative stress biomarkers such as oxidized low-density lipoprotein (oxLDL), glutathione (GSH), and F2-isoprostane. We also assessed whether FRC modulates plasma levels of polyunsaturated fatty acids (PUFA) in healthy individuals. The subjects (n=48) were randomly assigned to a low-cocoa group (1 g/d; ~55 mg flavanols) (n=16), middle-cocoa group (2 g/d; ~110 mg flavanols) (n=16), or a high-cocoa group (4 g/d; ~220 mg flavanols) (n=16). The samples were collected at baseline, at 1, 2, and 4 h post initial consumption of FRC, and after 4 weeks of FRC supplementation. The peak plasma concentration of (-)-epicatechin metabolites reached a maximum level (578±61 nM; P<.05) at 2 h after ingestion of FRC. After 4 weeks, total cholesterol (-12.37±6.63; P<.0001), triglycerides (-3.81±2.45; P<.0001), plasma LDL (-14.98±6.77; P<.0001), and oxLDL (-95.61±41.69; P<.0001) decreased in the high-cocoa group, compared with baseline. We also found that plasma high-density lipoprotein (HDL) (+3.37±2.06; P<.0001) concentrations increased significantly in the same group. Total GSH significantly increased in all FRC-treated groups (+209.73±146.8; P<.0001), while urinary F2-isoprostane levels decreased in the middle- (-0.73±0.16; P<.0001) and high-cocoa (-1.62±0.61; P<.0001) groups. At the end of the four-week study, a significant reduction of arachidonic acid (AA)/eicosapentaenoic acid (EPA) ratio was observed in the low-(-2.62±2.93; P=.003), middle- (-5.24±2.75; P<.0001) and high-cocoa (-7.76±4.96; P<.0001) groups, compared with baseline. Despite the small sample size used in this study, these data extend previous clinical and experimental studies, providing new insights into the health benefits of cocoa flavanols.

Because no controlled clinical studies are available about the possible role of angiotensin II receptor blockers in preventing effort myocardial ischemia, we evaluated the effect of angiotensin II receptor blocker/losartan in preventing exercise-induced myocardial ischemia in patients with coronary artery disease. Twenty-four sedentary patients with chronic stable ischemia were prospectively randomized to 28 days (double blind) of losartan 100 mg or losartan placebo in 2 divided doses. In each patient the treatment was crossed over to the alternative regimen (28 days, double blind) after a 1-week placebo period (single blind). At the end of each phase a new exercise stress test was performed. At baseline, systolic blood pressure was significantly decreased after losartan 100 mg compared with losartan placebo. At submaximal exercise, systolic blood pressure and rate–pressure product were lower after losartan 100 mg administration compared with losartan placebo, and these findings remained significant at 1-mm ST depression and at peak exercise. Losartan 100 mg administration versus losartan placebo significantly delayed the time to 1-mm ST-depression onset and decreased ST-segment depression at peak exercise and time to recovery of ST-segment depression. Losartan 100 mg administration compared with losartan placebo was able to significantly increase exercise duration and maximal workload during exercise stress testing. In conclusion, in our study, losartan decreased electrocardiographic parameters of myocardial ischemia in patients with coronary artery disease, suggesting a possible role of this drug in treatment of patients with effort myocardial ischemia.

Abstract: The aim of this study was to test the effects of age and chronic exercise training on antioxidant and heat shock protein (Hsp) expression by comparing the hearts of young (Y), sedentary old (SO) and trained old (TO) rats. In SO rats, there were: (a) changes in myocardial structure and function; (b) increased malondialdehyde levels; (c) no changes in superoxide-dismutase (SOD) enzymes; (d) reduced Hsp70 expression; and (e) increased Hsp27 expression. In TO rats, SOD enzymes and Hsp70 expression were increased and Hsp27 was further increased. Malondialdehyde level did not differ between TO and SO rats, which shows that chronic exercise did not affect the peroxidation index. In summary, by increasing Hsp27 and Hs70 levels, prolonged exercise partially counterbalanced the heart age-related effects in the antioxidant system without altering peroxidation levels. These findings suggest that the beneficial effects on aged-related cardiovascular changes could be connected to the “anti-oxidant” effects of prolonged exercise training. [Copyright &y& Elsevier]

Abstract: The phenomenon of elderly sexual offenders is poorly catalogued, and is especially complex. In institutions, elderly people are often unrecognized victims of sexual abuse but are also at great risk for doing abuse toward vulnerable victims like children. The lack of attention to an elder’s basic needs can endanger or impair not only his or her health or safety but also that of other people living close together. In this article, for the first time we describe an episode of sexual abuse realized by an institutionalized patient toward a young visitor. This specific risk factor in a residential care home for elderly may lead to a variety of negative behavioral outcomes, including the perpetration of child sexual offending. As the elderly population will increase tremendously in the next years, it is necessary to better understand the motivations and psychological factors relating to elderly sex offenders, to prevent these offenses, and to define standards for surveillance of residents who are potential perpetrators.

MEDITERRANEAN diet , *TELOMERES , *BIOMARKERS , *AGING , *MORTALITY - Abstract
Highlights • Adherence to a Mediterranean diet (MD) has been associated with a lower risk of all-cause mortality. • Telomere length (TL) is considered a biomarker of ageing. • Accelerated telomere shortening is associated with the onset of several age-associated health problems. • Age-dependent telomere attrition has been shown to be accelerated by oxidative stress and inflammation. • The protective effects of the MD and its food groups on oxidative stress and inflammation may explain the positive influence of the MD on TL. Abstract The Mediterranean diet (MD) is a gold standard for nutrition and the most evidence-based diet to delay the onset of age-associated pathologies. Telomeres are the heterochromatic repeat regions found at the ends of eukaryotic chromosomes, whose length is considered a reliable hallmark of biological ageing. Telomere shortening is, at least in part, a modifiable factor and there is evidence that adherence to the MD is associated with longer telomeres. Data from several studies indicate an association between "inflammatory/oxidative status" and telomere length (TL). The MD, as a complex exposome with thousands of nutrients and phytochemicals, may positively influence telomere attrition by reducing inflammation and oxidative stress. However, it is unclear whether the protective effects on TL provided by the MD result from its individual constituents or some combination of these. Furthermore, these properties of the MD and its components are not yet fully validated by clinical endpoints in randomized trials or observational studies. Here, we summarize the data from experimental and population-based studies on the effects of the MD on TL maintenance. We will both highlight the possible role of the MD in the prevention of age-associated diseases, and attempt to identify certain aspects of the diet that are particularly important for telomere maintenance.

UNSATURATED fatty acids , *OXIDATIVE stress , *INFLAMMATION , *SERUM , *MALONDIALDEHYDE - Abstract
Polyunsaturated fatty acids (PUFA) are known to have a regulatory effect on oxidative and inflammatory processes. This study aimed to identify the relationship between blood PUFA status and circulatory markers of oxidative stress and inflammation in a cohort of 172 subjects. The population was divided by sex and into three age groups: adults (18–64 years old, n = 69), older adults (65–89 years old, n = 54), and long-lived individuals (LLIs, 90–111 years old, n = 49). Whole blood PUFA content was quantified using gas chromatography. Additionally, serum levels of C-reactive protein (CRP), paraoxonase (PON), Trolox equivalent antioxidant capacity (TEAC), and malondialdehyde (MDA) were measured. Our results showed that a higher omega-3 (n-3) index in adult females was a predictor of lower MDA concentrations (p = 0.038). Conversely, total n-3 PUFA and total n-6 PUFA were positively related to MDA values among older adult females and LLI men (p < 0.05), while total n-6 PUFA was inversely correlated with MDA levels in LLI females (p < 0.05). Interestingly, increased concentrations of total n-3 PUFA and n-3 index were positively correlated with higher TEAC values in LLI men (p = 0.007), while the arachidonic acid (AA)/eicosapentaenoic acid (EPA) ratio was inversely correlated with TEAC values among LLI females (p = 0.006). These findings suggest that cellular antioxidant capacity is inversely correlated with changes in the AA/EPA ratio in long-lived females, whereas n-3 PUFA may enhance blood antioxidant capacity in long-lived men. Overall, our study highlights the complex, sex-specific interactions between PUFA profiles and oxidative stress and inflammatory markers across different age groups. • Polyunsaturated fatty acids (PUFA) may influence oxidative stress and inflammation across the lifespan. • Higher omega-3 (n-3) PUFA levels are linked to better antioxidant capacity in long-lived men. • Arachidonic acid (AA)/eicosapentaenoic acid (EPA) ratio is inversely related to antioxidant capacity in long-lived females. • Adult females with higher n-3 index showed lower malondialdehyde (MDA).

Objective: This study was designed to evaluate the effects of equol and resveratrol supplementation on health-related quality of life (HRQoL) in otherwise healthy menopausal women with hot flashes, anxiety and depressive symptoms.Methods: Sixty recently menopausal women aged 50-55 years were randomized in a 12-week, placebo-controlled trial to receive 200mg of fermented soy containing 10mg of equol and 25mg of resveratrol (1 tablet/day). The primary outcome was the change in score on the Menopause Rating Scale (MRS), used to evaluate the severity of age-/menopause-related complaints. Additional outcome measures included the subject-reported score on the Hamilton Rating Scale for Depression (HAM-D) and Nottingham Health Profile (NHP), which was used specifically to assess sleep quality.Results: The symptoms assessed by the MRS improved during treatment in the active group. Comparison between placebo and treatment groups revealed statistically significant improvement in particular for dryness of vagina (-85.7%) (p<0.001), heart discomfort (-78.8%; p<0.001) and sexual problems (-73.3%; p<0.001). On the HAM-D significant improvements at week 12 were seen in work and activities (-94.1%) (p<0.001). Subjects treated with equol and resveratrol also had significant differences in the sleep domain of the NHP (p<0.001).Conclusion: These findings provide evidence that 12 weeks of dietary supplementation with equol and resveratrol may improve menopause-related quality of life in healthy women.

ATRIAL fibrillation , *COGNITION disorders , *OLDER people , *AFFECTIVE disorders , *HEART failure , *PULMONARY embolism - Abstract
• Atrial Fibrillation (AF) is the most common arrhythmia worldwide, its prevalence raises with age and it is expected to increase in the next decades. • It is related to augmented risk of ischemic stroke or systemic embolism, as well-documented in the literature, and other less investigated conditions. • Many theories have emerged on mechanisms linking AF to heart failure, pulmonary embolism, risk of fall, disability, mood disorders and cognitive impairment. • Intrinsic features of the elderly make the management of AF and its complications particularly complex in this population. • Further studies are needed to better define the pathophysiology underlying the link between AF and its non-stroke complications. Atrial fibrillation (AF) represents the most common arrhythmia worldwide and its prevalence exponentially increases with age. It is related to increased risk of ischemic stroke or systemic embolism, which determines a significant burden of morbidity and mortality, as widely documented in the literature. AF also constitutes a risk factor for other less investigated conditions, such as heart failure, pulmonary embolism, impairment in physical performance, reduced quality of life, development of disability, mood disorders and cognitive impairment up to dementia. In the elderly population, the management of AF and its complications is particularly complex due to the heterogeneity of the ageing process, the lack of specific evidence-based recommendations, as well as the high grade of comorbidity and disability characterizing the over 65 years aged people. In the present review, we aim to summarize the pieces of the most updated evidence on AF complications beyond stoke, mainly focusing on the elderly population. [ABSTRACT FROM AUTHOR]
