Periodontitis (PDS) is a chronic inflammatory disease initiated by a dysbiosis of oral pathogenic bacterial species, such as Porphyromonas gingivalis (Pg). These bacteria can penetrate the bloodstream, releasing various endo and exotoxins that fuel the infection, and stimulate toxic inflammation in different compartments, including the brain. However, the specific mechanisms by which PDS/Pg contribute to brain disorders, such as Alzheimer's disease (AD), remain unclear.

To determine the optimal frequency and site of stimulation for transcutaneous vagus nerve stimulation (tVNS) to induce acute changes in the autonomic profile (heart rate (HR), heart rate variability (HRV)) in healthy subjects (HS) and patients with heart failure (HF).We designed three single-blind, randomized, cross-over studies: (1) to compare the acute effect of left tVNS at 25 Hz and 10 Hz (= 29, age 60 ± 7 years), (2) to compare the acute effect of left and right tVNS at the best frequency identified in study 1 (= 28 age 61 ± 7 years), and (3) to compare the acute effect of the identified optimal stimulation protocol with sham stimulation in HS and HF patients (= 30, age 59 ± 5 years, and= 32, age 63 ± 7 years, respectively).In study 1, left tragus stimulation at 25 Hz was more effective than stimulation at 10 Hz in decreasing HR (-1.

Parkinson's disease (PD) is a chronic neurodegenerative disease associated with a progressive loss of dopaminergic neurons, clinically characterized by motor and non-motor signs. Frailty is a clinical condition of increased vulnerability and negative health outcomes due to the loss of multiple physiological reserves. Chronic hyperglycemia and insulin resistance, which characterize diabetes mellitus (DM), have been reported to alter dopaminergic activity, increase the risk of PD, and influence the development of frailty.

Article Synopsis
  • - Subclinical hypothyroidism (SH) is a condition marked by elevated serum TSH levels with normal free T4, affecting 0.6% to 1.8% of adults, and has been linked to worse outcomes in heart failure patients.
  • - A study analyzed 277 heart failure patients, with 23 having SH, and found no significant demographic or health differences between those with SH and those who were euthyroid (normal thyroid function).
  • - Results indicated that SH is an independent predictor of cardiovascular mortality, emphasizing the need for thyroid testing in heart failure patients to potentially enhance their treatment and outcomes.

Introduction: The adipokines leptin and adiponectin have been associated with atherosclerosis and the risk of cerebral infarcts. Pre-clinical studies, however, suggest a protective role against ischemic brain damage. In this study we analyzed the relationship between serum leptin and adiponectin levels and the onset or progression of brain infarcts in subjects with mild cognitive impairment (MCI) and Alzheimer's disease (AD).

This study aimed to assess the main clinical and anamnestic characteristics of adult Cystic Fibrosis (CF) patients and to evaluate the association of frailty with the CF genotyping classification. In an observational cross-sectional study, all ambulatory CF patients over 18 years old who received a diagnosis at the Regional Cystic Fibrosis Center for adults were enrolled and assessed by spirometry for respiratory function, by ADL and IADL for functional status, and by the Study of Osteoporotic Fractures (SOF) Index for frailty. The study population consisted of 139 CF patients (mean age 32.

Numerous evidence reports direct correlation between cognitive impairment, Alzheimer's disease and sleep disorders, in particular obstructive sleep apnea. Both obstructive sleep apnea and Alzheimer's disease are highly prevalent conditions whose incidence increases with age. Several studies demonstrate how sleep-disordered breathing may lead to poor cognition, even though the underlying mechanisms of this association remain partially unclear.

Background: Pharmacogenomic factors affect the susceptibility to drug-drug interactions (DDI). We identified drug interaction perpetrators among the drugs prescribed to a cohort of 290 older adults and analysed the prevalence of gene polymorphisms that can increase their interacting potential. We also pinpointed clinical decision support systems (CDSSs) that incorporate pharmacogenomic factors in DDI risk evaluation.

Limitation in exercise capacity has not been described in athletes affected by SARS-CoV-2 infection. However, patients who have recovered from COVID-19 without cardiopulmonary impairment show exaggerated ventilatory response during exercise. Therefore, we aimed to evaluate the ventilatory efficiency (VEf) in competitive athletes recovered from COVID-19 and to characterize the ventilation versus carbon dioxide relationship (VE/VCO ) slope in this population.

Background: Loss of brain-derived neurotrophic factor (BDNF)/TrkB (tropomyosin kinase receptor B) signaling accounts for brain and cardiac disorders. In neurons, β-adrenergic receptor stimulation enhances local BDNF expression. It is unclear if this occurs in a pathophysiological relevant manner in the heart, especially in the β-adrenergic receptor-desensitized postischemic myocardium.

Article Synopsis
  • This study investigated the relationship between neuropsychiatric symptoms (like depression and irritability) and cognitive function in individuals with Mild Cognitive Impairment (MCI), who are at risk for developing Alzheimer's Disease (AD).
  • Out of 233 MCI subjects, over 61% exhibited neuropsychiatric symptoms, negatively impacting their cognitive abilities related to executive functions and leading to smaller brain volumes in specific areas like the orbitofrontal and posterior cingulate cortices.
  • Understanding how these symptoms connect to cognitive and brain changes may help in creating better treatments for MCI and potentially slow the progression to AD.

Introduction: In the risk stratification and selection of patients with heart failure (HF) eligible for implantable cardioverter-defibrillator (ICD) therapy, I-meta-IodineBenzylGuanidine ( I-mIBG) scintigraphy has emerged as an effective non-invasive method to assess cardiac adrenergic innervation. Similarly, clinical risk scores have been proposed to identify patients with HF at risk of all-cause mortality, for whom the net clinical benefit of device implantation would presumably be lower. Nevertheless, the association between the two classes of tools, one suggestive of arrhythmic risk, the other of all-cause mortality, needs further investigation.

Article Synopsis
  • - Heart failure (HF) is a significant health issue, with a rise in cases of HF with preserved ejection fraction (HFpEF), currently making up about 50% of all HF patients, which is increasing in prevalence.
  • - A study analyzed levels of various angiogenic and lymphangiogenic factors, finding reduced ANGPT1 in HFrEF patients and increased ANGPT2 in both HFrEF and HFpEF compared to healthy individuals, suggesting different inflammatory profiles between these types of HF.
  • - The findings indicate that specific proinflammatory regulators are altered differently in HFpEF and HFrEF, which may have clinical implications; however, more research with larger patient groups is needed to confirm these results.
