Neurocognitive, mood changes, and sleepiness in patients with REM-predominant obstructive sleep apnea.

Purpose: This article focuses on recent evidence linking rapid eye movement (REM) obstructive sleep apnea (OSA) (REM-OSA) to neurocognitive dysfunction and mood changes; the proposed mechanisms for increased risk of neurocognitive dysfunction in REM-OSA, and future research prospects.

Methods: PubMed and Google Scholar records were examined for articles utilizing pre-defined keywords. In this work, we mainly included studies published after 2017; nevertheless, critical studies published prior to 2017 were considered.

Rapid eye movement predominant obstructive sleep apnoea: prognostic relevance and clinical approach.

Purpose Of Review: Rapid eye movement (REM) obstructive sleep apnoea (OSA) is a stage-specific OSA, in which obstructive events occur primarily during REM sleep. This review discusses REM-OSA definitions, its cardiometabolic correlates, associated comorbidities and treatment, and addresses diagnostic ambiguities and therapeutic pitfalls.

Recent Findings: Current evidence indicates that REM-OSA is prevalent among younger age groups and women and is independently associated with cardiometabolic complications, particularly hypertension, metabolic complications such as insulin resistance and metabolic syndrome.

Exploding Head Syndrome: A Case Series of Underdiagnosed Hypnic Parasomnia.

Exploding head syndrome (EHS) is an under-recognized parasomnia characterized by a complaint of sudden loud noise or a sense of explosion in the head that usually occurs at sleep onset. This paper is a report of 6 patients diagnosed with EHS through a structured clinical interview and video-polysomnography (vPSG) recordings. We also reviewed the available literature that addressed the presentation and clinical and PSG characteristics of EHS.

Reopening Sleep Medicine Services in the Conundrum of an Ongoing COVID-19 Pandemic: A Global View.

The emergence of COVID-19 brought all healthcare services around the globe to immense strain; hospitals abandoned elective care for acute care. Like all other elective services, sleep medicine services suffered a partial deadlock due to the closing down of the sleep disorders diagnostic and therapeutic services, although clinical consultations and follow-ups, carried on remotely, allowed some mitigation. Since there is dire need to resume the services, we tried to formulate the principles and guidelines to work in this exigent healthcare setting.

Management of Aerosol during Noninvasive Ventilation for Patients with Sleep-Disordered Breathing: Important Messages during the COVID-19 Pandemic.

With the advent of COVID-19 infection and its rapid spread, preventive strategies are being developed worldwide, besides following the universal infection control guidelines. Prevention of spread through aerosol generation is one of the essential strategies in this regard, particularly for patients with sleep-disordered breathing at home and during hospital admission. Aerosols are produced, at home and in health care facilities, by natural processes and aerosol-generating procedures.
