2024 Standardization of Polysomnography Reports - A Consensus of the Brazilian Sleep Association.

 The absence of standardized reporting for sleep medicine exams across different laboratories can lead to misinterpretation, diagnostic inconsistencies, and suboptimal treatment strategies. This document seeks to establish guidelines for the development of sleep study reports, covering recordings from studies of types 1 to 4, and represents the official position of Associação Brasileira do Sono (ABS; Brazilian Sleep Association) on the standardization of polysomnography (PSG) and cardiorespiratory polygraphies.  The recommendations for the items to be reported in PSG records were developed by means of a Delphi study, comprised of two voting rounds.

Brazilian Consensus on Sleep-Focused Speech-Language-Hearing Sciences - 2023 Brazilian Sleep Association.

 This consensus aimed to develop a structured document presenting the role of sleep-focused Speech-Language-Hearing (SPH) Sciences (SPHS). The recommendations were based on the expertise of specialists and on evidence in the literature, aiming to guide the coverage of this area and the consequent improvement in the quality of the professionals' approach.  A Delphi method was conducted with 49 SLH pathologists (SLHP), four sleep physicians, one dentist, one physical therapist, and one methodologist.

Prevalence of awake bruxism in the adult population: a systematic review and meta-analysis.

Objectives: To evaluate the prevalence of awake bruxism (AB) in the adult population.

Materials And Methods: Six main electronic databases and three sources of grey literature were searched to identify cross-sectional studies in which AB was assessed. The studies were independently selected by two reviewers in two phases, based on their eligibility criteria.

Viscosupplementation in the upper and lower compartments of the temporomandibular joint checked by ultrasonography in an ex vivo and in vivo study.

Viscosupplementation (VS) of the temporomandibular joint (TMJ) aims to treat temporomandibular dysfunction (TMD) by stimulating synovial cells to improve intracapsular lubrication. The purpose of the present study was to assess a VS protocol planned with the aid of cone-beam computed tomography (CBCT) and checked by ultrasonography (US). The study was carried out in 3 stages.

COVID-19 - The clinical consequences of social isolation and the relation with sleep bruxism and comorbidities.

SARS-COV-2 is a highly pathogenic coronavirus that causes the disease known as COVID-19, which has infected more than 100 million people worldwide. The main form of containment of the pandemic is social isolation. However the isolation, the severity of the COVID-19 disease, the uncertainty of the future and the economic impact are the possible causes of anxiety as an adverse effect of the pandemic.

Analgesic potential of different available commercial brands of botulinum neurotoxin-A in formalin-induced orofacial pain in mice.

The use of botulinum neurotoxin-A (BoNT-A) is an alternative for the management of orofacial pain disorders. Although only Botox has labeled, there are other commercial brands available for use, among them: Dysport, Botulift, Prosigne, and Xeomin. The objective of the present study was to evaluate the possible differences in the antinociceptive effect evoked by different commercially available formulations of BoNT-A in an animal model of inflammatory orofacial pain induced by formalin injection.

COVID-19 and dental sleep medicine: risks, precautions and patient guidance.

COVID-19 is the offcial name for the disease caused by SARS-CoV-2, which has become a pandemic, infecting more than 5 million people worldwide. Transmission occurs by inhaling droplets generated when an infected person coughs, sneezes or exhales, or by touching contaminated surfaces and then rubbing their hands over their eyes, nose or mouth. Some infected people become seriously ill, while others have no symptoms, but even though they are asymptomatic, they can still transmit the virus.

An Operational Clinical Approach in the Diagnosis and Management of Sleep Bruxism: A First Step Towards Validation.

Exacerbation of nighttime sleep-related oromotor activity is often recognized as a relevant clinical entity commonly known as sleep bruxism (SB). Many pragmatic issues about SB diagnosis and management remain controversial. Therefore, within a critical review of the literature, this article proposes an operational clinical approach for SB diagnosis and management, with a focus on three comorbidities frequently occurring in relation to sleep: obstructive sleep apnea (OSA), gastroesophageal reflux disease (GERD), and insomnia.

Is there an association between sleep bruxism and obstructive sleep apnea syndrome? A systematic review.

Purpose: To elucidate current knowledge on the potential association and causality between sleep bruxism (SB) and obstructive sleep apnea (OSA) using full-night polysomnography.

Methods: Search strategies were developed for PubMed, Web of Science, Cochrane, LILACS, MEDLINE, and BBO-ODO and conducted until May 2019. The methodological quality was evaluated using the Qu-ATEBS tool.

Using craniofacial characteristics to predict optimum airway pressure in obstructive sleep apnea treatment.

Introduction: Manual titration is the gold standard to determinate optimal continuous positive airway pressure, and the prediction of the optimal pressure is important to avoid delays in prescribing a continuous positive airway pressure treatment.

Objective: To verify whether anthropometric, polysomnographic, cephalometric, and upper airway clinical assessments can predict the optimal continuous positive airway pressure setting for obstructive sleep apnea patients.

Methods: Fifty men between 25 and 65 years, with body mass indexes of less than or equal to 35kg/m were selected.

Predictors of success for mandibular repositioning appliance in obstructive sleep apnea syndrome.

The characteristics of non-obese patients with mild to moderate Obstructive Sleep Apnea Syndrome (OSAS) who will present with a good response to Mandibular Repositioning Appliance (MRA) treatment have not yet been well established in the literature. The aim of this study is to assess whether polysomnographic (PSG), demographic, anthropometric, cephalometric, and otorhinolaryngological parameters predict MRA success in the treatment of OSAS. Forty (40) males with mild and moderate OSAS were assessed pretreatment and 2-months post-treatment after wearing an MRA.

Does physical exercise reduce excessive daytime sleepiness by improving inflammatory profiles in obstructive sleep apnea patients?

Introduction: Obstructive sleep apnea syndrome (OSAS) is associated with a variety of long-term consequences such as high rates of morbidity and mortality, due to excessive diurnal somnolence as well as cardiovascular and metabolic diseases. Obesity, recurrent episodes of upper airway obstruction, progressive hypoxemia, and sleep fragmentation during sleep cause neural, cardiovascular, and metabolic changes. These changes include activation of peripheral sympathetic nervous system and the hypothalamic-pituitary-adrenal axis, insulin sensitivity, and inflammatory cytokines alterations, which predispose an individual to vascular damage.

Class II correction improves nocturnal breathing in adolescents.

Objective: To examine modifications in sleep pattern and in craniofacial morphology of adolescents with mandibular retrognathism.

Materials And Methods: Sixteen subjects at maximum pubertal growth (12.6 years [±11.
