New Horizons in Menopause, Menopausal Hormone Therapy, and Alzheimer's Disease: Current Insights and Future Directions.

Accumulating evidence suggests that the effects of menopausal hormone therapy (MHT) on risk of Alzheimer's disease (AD) and all-cause dementia are influenced by timing of initiation relative to age and time-since-menopause and the type of formulation. Randomized clinical trials (RCTs) of MHT conducted in older postmenopausal women indicate an increased risk of dementia. While RCTs conducted in midlife are lacking, observational research has provided evidence for associations between midlife estrogen-only therapy (ET) use and a reduced risk of AD dementia, whereas estrogen-progestogen therapy (EPT) is associated with more variable outcomes.

Sex-specific associations of serum testosterone with gray matter volume and cerebral blood flow in midlife individuals at risk for Alzheimer's disease.

Testosterone, an essential sex steroid hormone, influences brain health by impacting neurophysiology and neuropathology throughout the lifespan in both genders. However, human research in this area is limited, particularly in women. This study examines the associations between testosterone levels, gray matter volume (GMV) and cerebral blood flow (CBF) in midlife individuals at risk for Alzheimer's disease (AD), according to sex and menopausal status.

"Is every revision the same?" definition of complexity in knee revision surgery.

Purpose: The purpose of this paper is to define a subset of complex rTKA in terms of preoperative, intraoperative, and postoperative outcomes and complications. The secondary outcome of the authors is to propose a simple and easy-to-use guide for clinical network in rTKA management.

Methods: Complex rTKAs were defined according to the presence of at least two of the following features: periprosthetic joint infection, re- revision, femoral and/or tibial massive bone defects, soft tissue impairment, stiffness, fracture requiring fixed component revision.

In vivo brain estrogen receptor density by neuroendocrine aging and relationships with cognition and symptomatology.

17β-estradiol, the most biologically active estrogen, exerts wide-ranging effects in brain through its action on estrogen receptors (ERs), influencing higher-order cognitive function and neurobiological aging. However, our knowledge of ER expression and regulation by neuroendocrine aging in the living human brain is limited. This in vivo brain F-fluoroestradiol (F-FES) Positron Emission Tomography (PET) study of healthy midlife women reveals progressively higher ER density over the menopause transition in estrogen-regulated networks.

Systematic review of P-magnetic resonance spectroscopy studies of brain high energy phosphates and membrane phospholipids in aging and Alzheimer's disease.

Many lines of evidence suggest that mitochondria have a central role in aging-related neurodegenerative diseases, such as Alzheimer's disease (AD). Mitochondrial dysfunction, cerebral energy dysmetabolism and oxidative damage increase with age, and are early event in AD pathophysiology and may precede amyloid beta (Aβ) plaques. probes of mitochondrial function and energy metabolism are therefore crucial to characterize the bioenergetic abnormalities underlying AD risk, and their relationship to pathophysiology and cognition.

Communication and shared decision-making after stillbirth: Results of the ShaDeS study.

Background: Shared decision-making (SDM) is included in guidelines for bereavement care after a stillbirth, as it can improve women's long-term health and wellbeing. SDM within the stillbirth context is still not common, and Italy does not yet have standardised guidelines.

Aim: The ShaDeS (Shared Decision-Making in Stillbirth) study aims to investigate how Italian women with a stillbirth perceive their own centrality in decision-making processes around bereavement care and how this might impact satisfaction of care.

In vivo Brain Estrogen Receptor Expression By Neuroendocrine Aging And Relationships With Gray Matter Volume, Bio-Energetics, and Clinical Symptomatology.

17β-estradiol,the most biologically active estrogen, exerts wide-ranging effects in brain through its action on estrogen receptors (ERs), influencing higher-order cognitive function and neurobiological aging. However, our knowledge of ER expression and regulation by neuroendocrine aging in the living human brain is limited. This multi-modality neuroimaging study of healthy midlife women reveals progressively higher ER density over the menopause transition in estrogen-regulated networks.

Post-traumatic stress symptoms and burnout in healthcare professionals working in neonatal intensive care units: Results from the STRONG study.

Background: Newborns' deaths and life-threatening conditions represent extremely stressful events for parents and professionals working in NICUs, facilitating the onset of secondary traumatic stress symptoms. The STRONG study aims to better understand the psychological impact on Italian NICUs staff of bereavement care.

Methods: The STRONG (STress afteR lOss in NeonatoloGy) study is a cross-sectional study based on a web survey consisted of four sections: sociodemographic, CommuniCARE-Newborn questionnaire, the Maslach Burnout Inventory and the Impact of Event Scale-Revised.

Effects of sex and APOE ε4 genotype on brain mitochondrial high-energy phosphates in midlife individuals at risk for Alzheimer's disease: A 31Phosphorus MR spectroscopy study.

Age, female sex, and APOE epsilon 4 (APOE4) genotype are the three greatest risk factors for late-onset Alzheimer's disease (AD). The convergence of these risks creates a hypometabolic AD-risk profile unique to women, which may help explain their higher lifetime risk of AD. Less is known about APOE4 effects in men, although APOE4 positive men also experience an increased AD risk.

Elevated gonadotropin levels are associated with increased biomarker risk of Alzheimer's disease in midlife women.

Introduction: In preclinical studies, menopausal elevations in pituitary gonadotropins, follicle-stimulating hormone (FSH) and luteinizing hormone (LH), trigger Alzheimer's disease (AD) pathology and synaptic loss in female animals. Herein, we took a translational approach to test whether gonadotropin elevations are linked to AD pathophysiology in women.

Methods: We examined 191 women ages 40-65 years, carrying risk factors for late-onset AD, including 45 premenopausal, 67 perimenopausal, and 79 postmenopausal participants with clinical, laboratory, cognitive exams, and volumetric MRI scans.

Sex and menopause impact P-Magnetic Resonance Spectroscopy brain mitochondrial function in association with C-PiB PET amyloid-beta load.

Increasing evidence implicates sex and endocrine aging effects on brain bioenergetic aging in the greater lifetime risk of Alzheimer's disease (AD) in women. We conducted Phosphorus Magnetic Resonance Spectroscopy (P-MRS) to assess the impact of sex and menopause on brain high-energy phosphates [adenosine triphosphate (ATP), phosphocreatine (PCr), inorganic phosphate (Pi)] and membrane phospholipids [phosphomonoesters/phosphodiesters (PME/PDE)] in 216 midlife cognitively normal individuals at risk for AD, 80% female. Ninety-seven participants completed amyloid-beta (Aβ) C-PiB PET.

Phosphorus metabolism in the brain of cognitively normal midlife individuals at risk for Alzheimer's disease.

Background: Neurometabolic abnormalities and amyloid-beta plaque deposition are important early pathophysiologic changes in Alzheimer's disease (AD). This study investigated the relationship between high-energy phosphorus-containing metabolites, glucose uptake, and amyloid plaque using phosphorus magnetic resonance spectroscopy (P-MRS) and positron emission tomography (PET).

Methods: We measured P-MRS, fluorodeoxyglucose (FDG)-PET, and Pittsburgh Compound B (PiB)-PET in a cohort of 20 cognitively normal middle-aged adults at risk for AD.

Sex-Driven Differences in the Effectiveness of Individualized Clinical Management of Alzheimer's Disease Risk.

Background: The Comparative Effectiveness Dementia and Alzheimer's Registry (CEDAR) trial demonstrated that individualized, multi-domain interventions improved cognition and reduced the risk of Alzheimer's disease (AD). As biological sex is a significant risk factor for AD, it is essential to explore the differential effectiveness of targeted clinical interventions in women vs. men.

Exclusive breastfeeding and women's psychological well-being during the first wave of COVID-19 pandemic in Italy.

Background: At the onset of the COVID-19 pandemic, support for breastfeeding was disrupted in many countries. Italy was severely impacted by the pandemic and is known to have the lowest exclusive breastfeeding rate of all European countries. Considering the inverse association between anxiety and breastfeeding, maternal concerns about the COVID-19 emergency could reduce breastfeeding rates.

Ovarian steroid hormones: A long overlooked but critical contributor to brain aging and Alzheimer's disease.

Ovarian hormones, particularly 17β-estradiol, are involved in numerous neurophysiological and neurochemical processes, including those subserving cognitive function. Estradiol plays a key role in the neurobiology of aging, in part due to extensive interconnectivity of the neural and endocrine system. This aspect of aging is fundamental for women's brains as all women experience a drop in circulating estradiol levels in midlife, after menopause.
