Obstructive sleep apnea syndrome (OSAS) and swallowing function-a systematic review.

OBJECTIVES: The purpose of this systematic review was to summarize and qualitatively analyze published evidence elucidating the prevalence of dysphagia and detail alterations in swallowing function in patients with OSAS. METHODS: Computerized literature searches were performed from four search engines. The studies were selected based on the inclusion and exclusion criteria. The studies were screened using Covidence (Cochrane tool) and followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement standards (PRISMA-2009). A total 2645 studies were initially retrieved, of which a total of 17 studies met inclusion criteria. Two reviewers, blinded to each other, evaluated level and strength of evidence using the Oxford Centre for Evidence-based Medicine Levels of Evidence and QualSyst, respectively. RESULTS: Dysphagia prevalence ranged from 16 to 78% among the eligible studies. Studies varied in operational definitions defining swallowing dysfunction (dysphagia) and method used to assess swallowing function. Approximately 70% of eligible studies demonstrated strong methodological quality. The majority of studies (n = 11; 65%) reported pharyngeal swallowing impairments in patients with OSAS, including delayed initiation of pharyngeal swallow and penetration/aspiration. CONCLUSION: This systematic review describes swallowing function in patients with OSAS. However, due to the variability in defining OSAS and dysphagia, in the assessment method used to determine dysphagia, and heterogeneity of study designs, true prevalence is difficult to determine. Clinicians involved in the management of OSAS patients should employ validated assessment measures to determine if swallow dysfunction is present.

An organ systems-based review of outcomes associated with sleep apnea in hospitalized patients.

ABSTRACT: The current global health crisis due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has prompted the medical community to investigate the effects of underlying medical conditions, including sleep-disordered breathing, on inpatient care. Obstructive sleep apnea (OSA) is a common form of sleep-disordered breathing that may complicate numerous acquired conditions, particularly in inpatient and critical care settings. Viral pneumonia is a major contributor to intensive care unit (ICU) admissions and often presents more severely in patients with underlying pulmonary disease, especially those with obesity and OSA. This review summarizes the most recent data regarding complications of both OSA and obesity and highlights their impact on clinical outcomes in hospitalized patients. Additionally, it will highlight pertinent evidence for the complications of OSA in an organ-systems approach. Finally, this review will also discuss impatient treatment approaches for OSA, particularly in relation to the SARS-CoV-2 pandemic.

Alteration of Auto-CPAP requirements in obstructive sleep apnea patients with COVID-19 history.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is an infectious disease that leads to critical respiratory problems. Obstructive sleep apnea (OSA) is the most common sleep-associated breathing disease and is represented by repetitive experiences of constraint of the respiratory tract prompting to reduced or deficient breathing during sleep. Auto-Continuous positive airway pressure (Auto-CPAP) is a modality of respiratory ventilation used as gold standart in the treatment of OSA. OBJECTIVE: This study was performed to conclude the alteration of Auto-CPAP levels in OSA patients who had COVID-19 history. METHODS: Nineteen OSA patients who had cured COVID-19 and used Auto-CPAP were included in this study. Nightly Auto-CPAP 95th percentile pressure (95thpp), median CPAP pressure and AHI before COVID-19 disease and one month after COVID therapy were recorded from electronic cards of Auto-CPAP devices. RESULTS: Before COVID infection, average Auto-CPAP 95thpp was 8.56 ± 0.17 cm H2O. One month after COVID-19, average Auto-CPAP 95thpp was 9.78 ± 0.21 cm H2O (P < 0.01). While Median CPAP pressure was 7.49 ± 0.16 cm H2O before COVID, it was found to be 8.15 ± 0.19 cm H2O after the disease (P < 0.01). CONCLUSIONS: The increase in need of average Auto-CPAP 95thpp and median CPAP pressure in OSA patients who have had COVID-19 disease and use Auto-CPAP shows that this disease causes problems in both the lower and upper airways.

Symptomless multi-variable apnea prediction index assesses adverse outcomes in patients with Corona Virus Disease 2019.

PURPOSE: To explore the relationship between symptomless multi-Variable apnea prediction (sMVAP) index and adverse outcomes of patients with Corona Virus Disease 2019 (COVID-19). METHODS: According to the sMVAP quartiles, we divided all patients into four groups. The clinical electronic medical records, nursing records, laboratory findings, and radiological examinations for all patients with laboratory confirmed Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection were reviewed. Cox proportional hazard ratio (HR) models were used to determine the risk factors associated with in hospital death. RESULTS: A total of 97 patients were included in this study. The "Quartile 4" group 's ICU transfer rate was significantly higher than the "Quartile 1" group. Coronary heart disease, high d-dimer and sMVAP at admission were associated with increased odds of death. CONCLUSIONS: Using the sMVAP index for obstructive sleep apnea hypopnea syndrome (OSAHS) risk assessment, and then predicting the adverse outcomes of COVID-19 patients, is an effective method. Therefore, the use of sMVAP index for OSAHS screening for inpatients with COVID-19 should be vigorously promoted, and high-risk patients should be effectively managed.
