STUDY OBJECTIVES: Venous blood gases (VBGs) are not consistently considered suitable surrogates for arterial blood gases (ABGs) in assessing acute respiratory failure due to variable measurement error. The physiological stability of patients with chronic ventilatory failure may lead to improved agreement in this setting. METHODS: Adults requiring ABGs for sleep or ventilation titration studies had VBGs drawn before or after each ABG, in a randomized order. Veno-arterial correlation and agreement were examined for carbon dioxide tension (PCO2 ), pH, oxygen tension (PO2 ) and oxygen saturation (SO2 )...

BACKGROUND: Oral care is one of the fundamental nursing care procedures used to decrease oral colonization, dental plaque, respiratory infections, patient stay, and cost. The importance of good oral hygiene for patients in intensive care units (ICUs) is well recognized, however, the most effective way to achieve good oral care in the ICU is unclear. Therefore, the aim of this study was to assess the knowledge, attitude, and practice of nursing professionals regarding oral healthcare in ICUs among various medical institutes across India...

Background: Emergence delirium in children following strabismus surgery is a distressing and potentially dangerous condition and is likely attributable to visual disturbances, pain, and anesthetic gases. We explored whether a single intraoperative dose of methadone could reduce emergence delirium. Methods: Our study was an institutional review board-approved prospective, controlled, before-and-after investigation. Inclusion criteria were age <18 years and American Society of Anesthesiologists (ASA) classification 1 or 2...

Maxillomandibular advancement has been shown to be an effective treatment for obstructive sleep apnea; however, the literature focuses mainly on sleep-related parameters such as apnea-hypopnea index, respiratory disturbance index and Epworth sleepiness scale. Other factors that may be important to patients, such as esthetics, patient satisfaction, nasality, swallowing problems and so forth have been reported in the literature but have not been systematically studied. Together with an information specialist, an extensive search in Medline, Embase and Scopus yielded 1592 unique articles...

BACKGROUND: Coronary microvascular disease (CMD) is common in patients with and without obstructive coronary artery disease, and is associated with adverse clinical outcomes. Respiratory-related variables are associated with pulmonary and systemic microvascular dysfunction, while evidence regarding their relationship with CMD is limited. We aim to evaluate respiratory-related variables as risk factors of CMD. METHODS: This is an observational, single-center study enrolling consecutive patients undergoing invasive evaluation of coronary microvascular function in the catheterization laboratory...

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 caused an unprecedented pandemic for more than 2 years, affecting the lifestyle health, and education systems at the global level. During this long pandemic period, online learning was considered the only secure learning alternative. Multiple studies have demonstrated positive or negative perceptions related to online teaching. AIM: Through this study, we identified the perceptions and different challenges that online learning brought to the education of the students of Alexander Xhuvani University, Elbasan, focusing on their achievements...

RATIONALE: Regular, low-dose, sustained-release morphine is frequently prescribed for persistent breathlessness in chronic obstructive pulmonary disease (COPD). However, effects on daytime sleepiness, perceived sleep quality and daytime function have not been rigorously investigated. OBJECTIVES: Determine the effects of regular, low-dose, sustained-release morphine on sleep parameters in COPD. METHODS: Pre-specified secondary analyses of validated sleep questionnaire data from a randomized trial of daily, low-dose, sustained -release morphine versus placebo over four weeks commencing at 8mg or 16mg/day with blinded up-titration over two weeks to a maximum of 32mg/day...

INTRODUCTION: Overlap syndrome is the association of obstructive sleep apnea (OSA) with chronic obstructive pulmonary disorder and with other chronic respiratory diseases. Patients with overlap syndrome have a worse prognosis compared with chronic obstructive pulmonary disorder or OSA alone. Additionally, patients with combined chronic obstructive pulmonary disorder and OSA are more likely to develop pulmonary hypertension and right heart failure much earlier than those without overlap...

RATIONALE: The incidence of clinically undiagnosed obstructive sleep apnea (OSA) is high among the general population due to limited access to polysomnography. Computed tomography (CT) of craniofacial regions obtained for other purposes can be beneficial in predicting OSA and its severity. OBJECTIVES: To predict OSA and its severity based on paranasal CT using a 3-dimensional deep learning algorithm. METHODS: One internal dataset (n=798) and two external datasets (n=135 and 85) were used in this study...
