Age Differences and Prevalence of Comorbidities for Death and Survival in Patients with COVID-19: A Single-Center Observational Study in a Region of Southern Italy.

The SARS-CoV-2 outbreak has resulted in a considerable number of deaths worldwide. The virus damages the pulmonary artery endothelium, leading to a condition known as microvascular pulmonary inflammatory thrombotic syndrome (MPITS), which can be fatal and cause multiple organ failure. The presence of preexisting comorbidities has been shown to significantly impact the severity and prognosis of patients with SARS-CoV-2 infection.

Potential Impact of Physical Activity on Measures of Well-Being and Quality of Life in People with Rare Diseases: A Nationwide Cross-Sectional Study in Italy.

Background: Rare diseases constitute a heterogeneous group of approximately 7000-8000 conditions, distinguished by their low prevalence. Collectively, they present a significant global health challenge, affecting millions of people worldwide. It is estimated that rare diseases affect approximately 10% of the global population, which places a significant burden on individuals, families, and society.

The interplay between sodium/glucose cotransporter type 2 and mitochondrial ionic environment.

Mitochondrial volume is maintained through the permeability of the inner mitochondrial membrane by a specific aquaporin and the osmotic balance between the mitochondrial matrix and cellular cytoplasm. Various electrolytes, such as calcium and hydrogen ions, potassium, and sodium, as well as other osmotic substances, affect the swelling of mitochondria. Intracellular glucose levels may also affect mitochondrial swelling, although the relationship between mitochondrial ion homeostasis and intracellular glucose is poorly understood.

A Narrative Review Exploring the Similarities between Cilento and the Already Defined "Blue Zones" in Terms of Environment, Nutrition, and Lifestyle: Can Cilento Be Considered an Undefined "Blue Zone"?

Longevity is rightly considered one of the greatest achievements of modern society, not only as a function of lifespan, but, more importantly, as a function of healthspan. There are Longevity Blue Zones (LBZs), regions around the world, such as in Okinawa, Japan; the Nicoya Peninsula, Costa Rica; Loma Linda, California; Icaria, Greece; and Ogliastra, Sardinia, that are characterized by a significant percentage of residents who live exceptionally long lives, often avoiding age-related disability to a significantly higher degree than in the Western way of life. Longevity is not a universal phenomenon, so if there are places in the world with characteristics similar to the LBZs, it is important to identify them in order to better understand what other factors, in addition to the known ones, might contribute to a long and healthy life.

The effectiveness of ibandronate in reducing the risk of nonvertebral fractures in women with osteoporosis: systematic review and meta-analysis of observational studies.

Background: Ibandronate is effective in reducing the risk of vertebral fractures, but experimental evidence offers conflicting results regarding nonvertebral fractures. Real-world evidence has been published evaluating the anti-nonvertebral fracture effect of ibandronate.

Aim: This meta-analysis of observational studies assessed the effectiveness of ibandronate in reducing the risk of nonvertebral fractures in women with osteoporosis.

Functional and Clinical Importance of SGLT2-inhibitors in Frailty: From the Kidney to the Heart.

SGLT2 (sodium-glucose cotransporter 2) enables glucose and sodium reabsorption in the kidney. SGLT2-inhibitors (also known as gliflozins, which include canagliflozin, dapagliflozin, empagliflozin, and ertugliflozin) act by increasing glycosuria, thereby reducing glycemia. These drugs are critical to reach and keep glycemic control, a crucial feature, especially in patients with comorbidities, like frail individuals.

Ibandronate in the Prevention of Vertebral and Nonvertebral Osteoporotic Fractures: A Systematic Review of Experimental and Observational Studies.

Background/objective: This study aims to evaluate ibandronate clinical effectiveness in the prevention of osteoporosis-related vertebral fractures (VFs) and nonvertebral fractures (NVFs) in the treatment of postmenopausal osteoporosis.

Methods: This systematic review was conducted in accordance with the Centre for Reviews and Dissemination's guidance and reporting in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement 2020. A literature search was performed in PubMed and EMBASE since their inception until February 7, 2022.

Functional role of miR-34a in diabetes and frailty.

Emerging evidence has shown that microRNAs (miRNAs) play critical role in the pathogenesis of several disorders. In the present minireview, we focus our attention on the functional role of a specific miRNA, namely miR-34a, in the pathophysiology of frailty and diabetes mellitus. Based on the current literature, we speculate that this miRNA may serve as a potential biomarker of frailty in diabetic older adults.

Classification of Pharmaceutical Policy Measures During the Portuguese Financial Crisis.

Background: A rise in pharmaceutical expenses in Portugal led to the introduction of policy measures aimed at controlling outpatient public costs. This research examines and categorizes the most common pharmaceutical measures implemented during the Troika intervention, as well as comparing this period of time to prior ones.

Methods: A hierarchical structure of descriptors was built to classify and group measures over a 20-year period, including whether they might be deemed austerity measures.

The Dopamine System: Insights between Kidney and Brain.

Background: Chronic kidney disease (CKD) is one of the most common diseases in adult age, and it is typical of older adults. Recent data suggest that almost half of the elders have CKD. It is now clear that CKD is accompanied, in the early stages, by cognitive impairment, together with depression and subtle abnormalities in motor control (such as gait and balance alterations).

Omega-3 fatty acids coordinate glucose and lipid metabolism in diabetic patients.

Omega 3 polyunsaturated fatty acids (n-3 PUFA) are known to have beneficial effects on cardiovascular and metabolic health. However, whether different sources of n-3 PUFA, for instance fatty fish vs vegetable oils, could elicit different effects on glucose and lipid metabolism, remains to be determined. Herein we examine recent findings showing that while a plant-based n-3 PUFA supplementation for six months can reduce fasting blood glucose, marine-based n-3 PUFA can instead reduce serum levels of triglycerides.

Physical decline and cognitive impairment in frail hypertensive elders during COVID-19.

Background: Hypertension is common in older adults and its incidence increases with age. We investigated the correlation between physical and cognitive impairment in older adults with frailty and hypertension.

Methods: We recruited frail hypertensive older adults during the COVID-19 pandemic, between March 2021 and December 2021.

Brain dysfunction in tubular and tubulointerstitial kidney diseases.

Kidney function has two important elements: glomerular filtration and tubular function (secretion and reabsorption). A persistent decrease in glomerular filtration rate (GFR), with or without proteinuria, is diagnostic of chronic kidney disease (CKD). While glomerular injury or disease is a major cause of CKD and usually associated with proteinuria, predominant tubular injury, with or without tubulointerstitial disease, is typically non-proteinuric.

Cognitive Impairment in Frail Hypertensive Elderly Patients: Role of Hyperglycemia.

Endothelial dysfunction is a key hallmark of hypertension, which is a leading risk factor for cognitive decline in older adults with or without frailty. Similarly, hyperglycemia is known to impair endothelial function and is a predictor of severe cardiovascular outcomes, independent of the presence of diabetes. On these grounds, we designed a study to assess the effects of high-glucose and metformin on brain microvascular endothelial cells (ECs) and on cognitive impairment in frail hypertensive patients.

Development of medicines consumption in Portugal before and during the financial crisis.

Background: In May 2011, the Portuguese Government signed a Memorandum of Understanding with the European Commission, the European Central Bank and the International Monetary Fund, including detailed measures to control health costs, allowing Portugal to receive a financial rescue package. This study aims to investigate medicines utilization in the outpatient sector during Troika's financial rescue.

Methods: Using Defined Daily Dose per million inhabitants per year as a measurement unit, we compared medicines utilization with other relevant indicators over 5-year intervals for a total period of 20 years, based on a built-in inventory of national outpatient drug use using the Intercontinental Medical Statistics Health and Anatomical Therapeutic Chemical index of the World Health Organization databases.

Dopamine: The Neuromodulator of Long-Term Synaptic Plasticity, Reward and Movement Control.

Dopamine (DA) is a key neurotransmitter involved in multiple physiological functions including motor control, modulation of affective and emotional states, reward mechanisms, reinforcement of behavior, and selected higher cognitive functions. Dysfunction in dopaminergic transmission is recognized as a core alteration in several devastating neurological and psychiatric disorders, including Parkinson's disease (PD), schizophrenia, bipolar disorder, attention deficit hyperactivity disorder (ADHD) and addiction. Here we will discuss the current insights on the role of DA in motor control and reward learning mechanisms and its involvement in the modulation of synaptic dynamics through different pathways.
