Tongue Ultrasonography in the Screening of Severe Obstructive Sleep Apnea Syndrome-Promising Potential for Overloaded Sleep Centers.

Obstructive sleep apnea syndrome (OSAS) is a frequently underdiagnosed sleep disorder marked by recurrent episodes of apnea and/or hypopnea during sleep, primarily resulting from the partial or complete collapse of the upper airway. OSAS significantly affects patients' health and quality of life. Additionally, it is a recognized risk factor for inducing microsleep episodes during daily activities, particularly in occupations such as professional driving, where sustained attention is critical.

Effect of sacubitril/valsartan on the hypertensive heart in continuous light-induced and lactacystin-induced pre-hypertension: Interactions with the renin-angiotensin-aldosterone system.

This study investigated whether sacubitril/valsartan or valsartan are able to prevent left ventricular (LV) fibrotic remodelling and dysfunction in two experimental models of pre-hypertension induced by continuous light (24 hours/day) exposure or by chronic lactacystin treatment, and how this potential protection interferes with the renin-angiotensin-aldosterone system (RAAS). Nine groups of three-month-old male Wistar rats were treated for six weeks as follows: untreated controls (C), sacubitril/valsartan (ARNI), valsartan (Val), continuous light (24), continuous light plus sacubitril/valsartan (24+ARNI) or valsartan (24+Val), lactacystin (Lact), lactacystin plus sacubitil/valsartan (Lact+ARNI) or plus valsartan (Lact+Val). Both the 24 and Lact groups developed a mild but significant systolic blood pressure (SBP) increase, LV hypertrophy and fibrosis, as well as LV systolic and diastolic dysfunction.

Ivabradine curbs isoproterenol-induced kidney fibrosis.

This study investigated whether chronic isoproterenol administration could induce kidney alterations and whether ivabradine, a heart rate (HR)-reducing substance exerting cardiovascular protection, is able to attenuate potential kidney damage. Twenty-eight Wistar rats were divided into non-diseased controls, rats treated with ivabradine, rats treated with isoproterenol, and rats treated with isoproterenol plus ivabradine. Six weeks of isoproterenol administration was associated with decreased systolic blood pressure (SBP) (by 25%) and glomerular, tubulointerstitial and vascular/perivascular fibrosis due to enhanced type I collagen volume (7-, 8-, and 4-fold, respectively).

Evaluation of Mobile and Community Dental Service Use among People Experiencing Homelessness.

The aim of the study was to evaluate the patterns of mobile and community dental service use among people experiencing homelessness in Bratislava, Slovakia. Data from medical records of homeless people who visited the mobile and community dental clinic from November 2012 to July 2018 have been retrospectively reviewed. The experience of providing dental services has been reported from the perspective of the dental care provider.
