AI Article Synopsis
- The study aimed to understand how common nocturia is in patients with obstructive sleep apnea syndrome (OSAS) and identify factors that might predict it.* -
- Researchers analyzed data from 1,264 untreated OSAS patients, finding that 35.2% of males and 59.8% of females reported experiencing nocturia, along with higher rates of depression, sleep issues, and associated health problems.* -
- The analysis revealed that for male patients, worse oxygen desaturation during sleep was a significant predictor of nocturia, suggesting that better evaluation of nocturia could be important in managing OSAS.*
Article Abstract
Objectives: Many patients with obstructive sleep apnea syndrome (OSAS) have nocturia. However, the predictive index of nocturia in patients with OSAS is currently not well known. We aimed to investigate the prevalence of nocturia in patients with OSAS and determine the factors that could predict nocturia in these patients.
Methods: In this retrospective cross-sectional study, we enrolled 1,264 untreated patients with OSAS (Apnea-Hypopnea Index, AHI ≥5/h on polysomnography [PSG]) from January 2017 to January 2020. Participants completed the Beck Depression Inventory-II (BDI-II), Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI), and Epworth Sleepiness Scale. Participants were divided by sex and then subdivided into nocturia and non-nocturia groups according to the following question, "Do you go to the bathroom two times or more during your sleep?" Participants' characteristics and underlying disease were investigated, and all information, including PSG data, was compared between the two groups using the t-test or chi-square test.
Results: Overall, 35.2% (337/958) of male participants with OSAS and 59.8% (183/306) of female participants with OSAS had nocturia. The nocturia group was older; scored higher on the BDI-II, PSQI, and ISI; and had more underlying disease in both sexes. There was no difference in the AHI between the two groups among both sexes, but the hypoxia-related PSG parameters and sleep quality parameters, such as higher 90% oxygen desaturation index (90% ODI), lesser N3 sleep, and higher wakefulness after sleep onset, were worse among male participants with OSAS in the nocturia group than in the non-nocturia group. In multivariate logistic analysis, 90% ODI was an independent risk factor associated with nocturia in male participants with OSAS.
Conclusions: Considerable number of patients with OSAS had nocturia and poor sleep quality. Nocturia should be evaluated in male OSAS patients with severe hypoxia observed during sleep.

Article Synopsis
- Obstructive sleep apnea syndrome (OSAS) is linked to cardiovascular risk factors from metabolic syndrome, including obesity, hypertension, and insulin resistance.
- A study aimed to determine how common metabolic syndrome is among adults with OSAS using various questionnaires and health assessments.
- Results showed that 55.4% of OSAS patients had metabolic syndrome, with factors like obesity and high blood pressure significantly correlating with the severity of OSAS.

Background: The aim of the current study is to measure the prevalence and the potential role of International Prostate Symptom Score (IPSS) score as a predictor of obstructive sleep apnea syndrome (OSAS) in male experienced lower urinary tract symptoms (LUTS).
Methods: A cross-sectional web-based Italian survey was administered via Google Forms between July 17 and October 31, 2022. The urinary functioning was measured through the IPSS questionnaire.

Postoperative urinary incontinence after robot-assisted radical prostatectomy (RARP) represents a bothersome side effect, which may permanently affect patient's quality of life. Several studies have demonstrated that obstructive sleep apnea syndrome (OSAS) is associated with urinary symptoms such as urge incontinence, overactive bladder, and nocturia. In this study, we sought to further explore the effect of OSAS on urinary continence after RARP.

Lower urinary tract symptoms represent a significant public health problem worldwide, impairing patients' quality of life, especially in elderly people. Among LUTS, nocturia is assessed as the most experienced entity related to several disorders such as sleep disorders and/or obstructive sleep apnea syndrome (OSAS). Among OSAS patients, nocturia stands as a bothersome symptom that increases alongside with the OSAS severity.

Purpose: To evaluate adherence to continuous positive airway pressure (CPAP) treatment in elderly patients newly diagnosed with obstructive sleep apnea syndrome (OSAS).
Methods: Consecutive patients ≥ 70 years attending one of the participating centers, requiring CPAP treatment and agreeing to participate, were included. Mean hours of CPAP during the first 5 months of treatment defined adherence as CPAP ≥ 4 h/day on 70% of nights over a 30-day period.
