Article Synopsis
  • The study examines how changing the criteria for hypopneas from 4% to 3% affects the scoring of respiratory events like RERAs (respiratory effort-related arousals) during sleep studies.
  • Results show that the new 3% RERA index is significantly lower than the previous 4% index, and the 3% Apnea-Hypopnea Index (AHI) is higher than the 4% Respiratory Disturbance Index (RDI), indicating more cases of obstructive sleep apnea (OSA) are identified under the new criteria.
  • The findings suggest that the updated hypopnea definitions lead to an increase in reported hypopneas, which

Duane syndrome is a form of congenital strabismus with horizontal eye movement limitation. This may present a diagnostic challenge when assessing for rapid eye movements during stage REM utilizing PSG or MSLT. We present a case of a child with Duane syndrome who presented with excessive daytime sleepiness and underwent evaluation for hypersomnia.

Unlabelled: Radiation therapy is the mainstay of treatment for head and neck cancers with both acute and delayed complications. While obstructive sleep apnea is common in the few series of patients undergoing radiation therapy to the neck, the development of sleep-related stridor is exceedingly rare and has typically been reported in the acute treatment setting. We describe a 65-year-old female with 1 year of nocturnal groaning beginning 2 years after radiation therapy for thyroid carcinoma.

Objectives: To examine if the presence of a certified child life specialist (CCLS) had a positive impact on patient emotion at the time of polysomnography setup and to determine the optimal timing of CCLS intervention prior to polysomnography (PSG) in our sleep center.

Methods: We implemented a study which measured the impact of a CCLS on the emotional manifestation score (EMS) of pediatric patients (4 months-17 years, median 7 years) during PSG setup. CCLS intervention was either at the time of sleep medicine consultation (daytime) or during PSG setup (evening).

Article Synopsis
  • As reliance on medical devices increases, recalls can cause anxiety and disruptions for patients, especially with common devices like positive airway pressure treatment machines.
  • An established recall plan helps healthcare providers respond quickly, minimizing stress and maintaining access for new patients while managing medical supplies.
  • Clear and empathetic communication with patients during recalls not only reduces their anxiety but also improves the overall effectiveness of the recall response plan.

Male breast cancer is a rather uncommon and understudied disease. It accounts for less than 1% of all breast cancers, but in recent decades its frequency has been on the rise. Clinical trials of breast cancer have traditionally excluded men.

Vaccination programs are considered a central pillar of the efforts to stop COVID-19. However, vaccine doses are scarce and several organizational and logistical obstacles, such as the timing of and reserves for second shots and delivery failures, apparently slow down vaccination roll-outs in several countries. Moreover, it is an open question as to where vaccines are administered as efficiently as possible (vaccination centers, hospitals, doctor's offices, pharmacists, etc.

Appendiceal mucinous neoplasms are a rare and heterogeneous group of diseases with challenging clinical management decisions. They account for less than 1% of all cancers but their incidence is on the rise. Treatment is based on their stage and histology.

Study Objectives: Pediatric polysomnography can result in suboptimal patient and provider (physician and advanced practice provider) experiences. We embarked on a project aimed at increasing the proportion of maximal satisfaction survey scores by a minimum of 10% in 1 year without adding personnel or major expenses.

Methods: We used a Six Sigma framework, define, measure, analyze, improve, and control (DMAIC), to conduct our analysis.

Study Objectives: At the sleep laboratory, noninvasive positive pressure ventilation titration protocols in patients with neuromuscular disease (NMD) are based on standard pressure cycle devices in a spontaneous/timed mode (BPAP-ST). Experience integrating protocols on average volume-assured pressure support (AVAPS) mode is limited, prompting us to develop a practical single-night titration protocol that provides information to assist clinicians and patients as they decide between BPAP-ST and AVAPS modes.

Methods: We implemented a sequential titration protocol of BPAP-ST followed by AVAPS during a single-night polysomnography study in patients with NMD and reported polysomnographic and clinical metrics.

Study Objectives: Health care complexity includes dimensions of patient comorbidity and the level of services needed to meet patient demands. Home sleep apnea tests (HSAT) are increasingly used to test medically uncomplicated patients suspected of having moderate to severe obstructive sleep apnea (OSA). Patients with significant comorbidities or other sleep disorders are not candidates for HSAT and require attended in-center polysomnography.

Background: Obstructive sleep apnea (OSA) is linked to both coronary artery disease (CAD) and sudden death, but any causal role remains unclear. A family history of premature CAD and related mortality is an independent risk factor for the development of CAD. We hypothesized that OSA is associated with a family history of premature mortality from ischemic heart disease.

Study Objectives: To obtain efficacy, objective compliance, and self-assessment data from obstructive sleep apnea syndrome (OSAS) patients treated with continuous positive airway pressure (CPAP) or a novel bilevel (NBL) therapy.

Design: Randomized, controlled, double-blind trial.

Setting: Home treatment after diagnosis and titration by split-night polysomnography (PSG) in a sleep laboratory.
