Background: The prognostic importance of preclinical markers of atherosclerosis and their interrelationship are inconclusive. In this study interrelationship between different methods investigating endothelial function and intima media thickness (IMT) was investigated in patients with polycystic ovary syndrome (PCOS).
Methods: Endothelial function was assessed by endothelium-dependent flow-mediated dilation (FMD), nitrate-mediated dilation (NMD), low-flow-mediated constriction (L-FMC) and peripheral arterial tonometry (PAT). Arterial stiffness was determined by pulse wave velocity (PWV) and the Augmentation Index (AI). The IMT of carotid arteries was measured.
Results: Twenty-eight obese women were recruited with the diagnosis of PCOS, mean age 27±7.2 years and Body Mass Index 38.8±6.3 kg/m2. A relationship between FMD and NMD (r=0.44, P=0.02) was shown. FMD as well as NMD of the brachial artery were not correlated with L-FMC or PAT. The AI and PWV, indicators of arterial stiffness were not interrelated with FMD, and there was no significant interrelationship between IMT and FMD or NMD. The AI was related only to IMT (r=0.45, P=0.30).
Conclusions: The relationship between available methods for evaluation of endothelial function/dysfunction is weak in PCOS. This indicates that different methods investigate different mechanisms and various sections of the circulatory system.

Background: In this phase 3 trial of an investigational maternal respiratory syncytial virus prefusion F protein-based vaccine (RSVPreF3-Mat), a higher rate of preterm birth was observed in the vaccine (6.8%) versus the placebo group (4.9%).

Background And Objectives: Lipid metabolism in older adults is affected by various factors including biological aging, functional decline, reduced physiologic reserve, and nutrient intake. The dysregulation of lipid metabolism could adversely affect brain health. This study investigated the association between year-to-year intraindividual lipid variability and subsequent risk of cognitive decline and dementia in community-dwelling older adults.

Background And Objectives: Invasive procedures may delay the diagnostic process in multiple sclerosis (MS). We investigated the added value of serum neurofilament light chain (sNfL), glial fibrillary acidic protein (sGFAP), chitinase-3-like 1 (sCHI3L1), and the immune responses to the Epstein-Barr virus-encoded nuclear antigen 1 to current MS diagnostic criteria.
Methods: In this multicentric study, we selected patients from 2 prospective cohorts presenting a clinically isolated syndrome (CIS).

Background: There is an increasing body of literature associating edentulism with cognitive impairment. The aim of this systematic review was to summarize the available data, emphasizing the role of removable dental prostheses in preventing cognitive deterioration and promoting brain health in elderly individuals.
Aim: This systematic review investigates the relationship between the use of removable dental prostheses and physiological or adaptive changes at the cerebral level in partially and completely edentulous patients.

Rationale: Previous studies evaluating the effect of continuous positive airway pressure (CPAP) in patients with obstructive sleep apnea (OSA) on blood pressure (BP) showed variable results. Moreover, several studies recruited patients with normal or controlled BP, and compliance to antihypertensive drugs was not monitored. In addition, very few studies investigated central BP in this scenario.
