Emergency visits of otorhinolaryngology department during COVID-19 pandemic, Saudi Arabia, 2020

Aim: In this study, we aimed to assess the frequency of patient emergency visits to the Otorhinolaryngology (ORL) Department during coronavirus COVID-19 pandemic and compare it with that before coronavirus COVID-19. Material(s) and Method(s): A retrospective comparative study was performed at Al-Al-Hada Armed Forces Hospital, Taif (Saudi Arabia), and data regarding various diagnoses of ORL cases were collected from medical records of patients who visited/admitted to ORL-ED during the lockdown (Group 1) and those who visited/ admitted to ORL-ED before the pandemic (Group 2). Result(s): Group 2 had a significantly higher percentage of cases who had no ENT-related disorders, hypertrophy inferior turbinate (HIT), stridor, obstructive sleep apnea (OSA), epistaxis and who had no complications, had general ENT, foreign body ingestion-aspiration, trauma, otology and who had more than one disorder and Group 1 had a significantly higher percentage of those having nasal obstruction, tonsil hypertrophy grade 3, had emergency head and neck cancer, had deep neck space infections and who had complicated. Discussion(s): During coronavirus COVID-19 pandemic period, cold ENT visits were much less and foreign body ingestion remains the highest reason for ENT visits. Additionally, telemedicine has been shown to be effective in reducing ED visits during the pandemic period. Furthermore, older cases with chronic ENT problems who had regular follow-up ENT visits were less likely to visit ED during the pandemic.Copyright © 2022, Derman Medical Publishing.

Associations between obstructive sleep apnea and COVID-19 infection and hospitalization among US adults.

STUDY OBJECTIVES: Medical comorbidities increase the risk of severe COVID-19 infection. In some studies, obstructive sleep apnea (OSA) has been identified as a comorbid condition that is associated with an increased prevalence of COVID-19 infection and hospitalization, but few have investigated this association in a general population. This study aimed to answer the following research question: In a general population, is OSA associated with increased odds of COVID-19 infection and hospitalization and are these altered with COVID-19 vaccination? METHODS: This was a cross-sectional survey of a diverse sample of 15,057 US adults. RESULTS: COVID-19 infection and hospitalization rates in the cohort were 38.9% and 2.9%, respectively. OSA or OSA symptoms were reported in 19.4%. In logistic regression models adjusted for demographic, socioeconomic, and comorbid medical conditions, OSA was positively associated with COVID-19 infection (adjusted odds ratio: 1.58, 95% CI: 1.39-1.79) and COVID-19 hospitalization (adjusted odds ratio: 1.55, 95% CI: 1.17-2.05). In fully adjusted models, boosted vaccination status was protective against both infection and hospitalization. Boosted vaccination status attenuated the association between OSA and COVID-19 related hospitalization but not infection. Participants with untreated or symptomatic OSA were at greater risk for COVID-19 infection; those with untreated but not symptomatic OSA were more likely to be hospitalized. CONCLUSIONS: In a general population sample, OSA is associated with a greater likelihood of having had a COVID-19 infection and a COVID-19 hospitalization with the greatest impact observed among persons experiencing OSA symptoms or who were untreated for their OSA. Boosted vaccination status attenuated the association between OSA and COVID-19-related hospitalization. CITATION: Quan SF, Weaver MD, Czeisler MÉ, et al.

Recurrent/Subsequent Stroke and Associated Outcomes in Geriatric Patients with OSA and Prior Stroke Events: A Retrospective Study Using the 2019 National Inpatient Sample.

Background: Obstructive sleep apnea (OSA) increases the risk of stroke and cardiovascular diseases. However, its impact on geriatric patients with a prior history of stroke/transient ischemic attack (TIA) has not been adequately studied. Methods: We utilized the 2019 National Inpatient Sample in the US to identify geriatric patients with OSA (G-OSA) who had a prior history of stroke/TIA. We then compared subsequent stroke (SS) rates among sex and race subgroups. We also compared the demographics and comorbidities of SS+ and SS- groups and utilized logistic regression models to assess outcomes. Results: Out of 133,545 G-OSA patients admitted with a prior history of stroke/TIA, 4.9% (6520) had SS. Males had a higher prevalence of SS, while Asian-Pacific Islanders and Native Americans had the highest prevalence of SS, followed by Whites, Blacks, and Hispanics. The SS+ group had higher all-cause in-hospital mortality rates, with Hispanics showing the highest rate compared to Whites and Blacks (10.6% vs. 4.9% vs. 4.4%, p < 0.001), respectively. Adjusted analysis for covariates showed that complicated and uncomplicated hypertension (aOR 2.17 [95% CI 1.78-2.64]; 3.18 [95% CI 2.58-3.92]), diabetes with chronic complications (aOR 1.28 [95% CI 1.08-1.51]), hyperlipidemia (aOR 1.24 [95% CI 1.08-1.43]), and thyroid disorders (aOR 1.69 [95% CI 1.14-2.49]) were independent predictors of SS. The SS+ group had fewer routine discharges and higher healthcare costs. Conclusions: Our study shows that about 5% of G-OSA patients with a prior history of stroke/TIA are at risk of hospitalization due to SS, which is associated with higher mortality and healthcare utilization. Complicated and uncomplicated hypertension, diabetes with chronic complications, hyperlipidemia, thyroid disorders, and admission to rural hospitals predict subsequent stroke.

Factors Associated with the Underestimation of Manual CPAP Titration Pressure.

During the SARS-CoV-2 pandemic, the use of in-laboratory positive airway pressure (PAP) titration studies was not routinely suggested. PAP pressure prediction calculations are emerging as alternative methods for the treatment of these patients. The underestimation of PAP titration pressure usually leads to unsatisfactory results for PAP therapy. This study aimed to evaluate the factors associated with the underestimation of PAP titration pressure when using PAP pressure prediction equations. Estimated PAP pressure formulas based on body mass index (BMI) and apnea-hypopnea index (AHI) were chosen to validate the accuracy of equations in the successful prediction of titration pressure. Among 341 adult patients diagnosed with obstructive sleep apnea (OSA) by overnight polysomnography (PSG) and who received overnight PAP titration in order to select a successful pressure, the mean age of the total subjects was 55.4 years old and 78.9% of patients were male. The average BMI and AHI scores were 27.1 ± 4.8 and 37 ± 21.7, respectively. After multivariate stepwise regression analysis, the odds ratio of participants with a pretitration AHI was 1.017 (95% CI: 1.005-1.030). Only the severity of OSA was significantly different between the underestimated group and the adequately assessed group. In conclusion, a high AHI, but not BMI, is associated with an underestimated CPAP titration pressure in adult patients with OSA.

Impact of the COVID-19 pandemic on positive airway pressure adherence and patients' perspectives in Greece: the role of telemedicine.

STUDY OBJECTIVES: To analyze the impact of national lockdowns in Greece on positive airway pressure (PAP) adherence, patients' perspectives regarding COVID-19 pandemic and the role of telemedicine. METHODS: 872 obstructive sleep apnea (OSA) patients from Southern and 673 from Northern Greece, under PAP treatment, were evaluated with adherence data available 12 months prior to and 3 months after the first and second lockdown. Telemedicine, locally available as part of a research protocol, was used for patient's follow-up in Southern Greece and standard follow up procedures were implemented in Northern Greece. We analyzed the impact of COVID-19 lockdown on PAP adherence, and patients concerns regarding COVID-19 infection. RESULTS: Significant difference was noted in PAP adherence as measured by the hours of use at 12 months prior to and at the 3 months after the first lockdown in Southern (5.6 vs 6.6, p=0.003) and Northern Greece (5.3 vs 6.0, p=0.03). The proportion of patients with optimal adherence (≥6 hours) increased by 18% (p=0.004) in Southern and by 9% (p=0.20) in Northern Greece after the first lockdown and remained steady after the second lockdown in both groups. In Southern Greece, 23% of patients reported that they were concerned about getting COVID-19 due to OSA diagnosis, while only 3% reported decreased sleep duration. Moreover, 9% were concerned that the presence of OSA would make them more susceptible for worse outcome in case of COVID-19 infection. CONCLUSIONS: Our results suggest that maintaining follow-up using telemedicine had a positive influence pointing out the potential role of digital health.

Obstructive sleep apnea and subsequent risk of hospitalization with pneumonia, respiratory infection, and total infection: The Atherosclerosis Risk in Communities Study.

BACKGROUND: Obstructive sleep apnea (OSA) has been linked to microaspiration, systemic inflammation and suboptimal immune function. RESEARCH QUESTION: Is OSA prospectively associated with risk of hospitalization with pneumonia, respiratory and total infections? STUDY DESIGN: Prospective cohort. METHODS: Participants of the Atherosclerosis Risk in Communities (ARIC) study (N=1,586) underwent polysomnography in 1996-1998 and were followed through 2018 for infection-related hospitalizations. The apnea-hypopnea index (AHI; events/hour) was used to categorize participants as having severe OSA (≥30), moderate OSA (15-29), mild OSA (5-14), or a normal breathing pattern (<5). Cox regression was used to calculate hazard ratios (HRs) and 95% confidence intervals (CI). RESULTS: ARIC participants were on average 62.7 (SD=5.5) years old, and 52.8% were female. Severe OSA was present in 6.0%, moderate OSA in 12.7%, mild OSA in 30.0% and normal breathing in 51.3%. A total of 253 hospitalizations with pneumonia occurred over a median 20.4 (max 22.9) years follow-up. Participants with severe OSA were at 1.87 times (95% CI: 1.19-2.95) higher risk of hospitalization with pneumonia compared to those with a normal breathing pattern after adjustment for demographics and lifestyle behaviors. Results were attenuated modestly after adjustment for body mass index [1.62 (0.99-2.63)], and prevalent asthma and COPD [1.62 (0.99-2.63)]. A similar pattern existed for hospitalization with respiratory infection and composite infection [demographic and behavior-adjusted HRs: 1.47 (0.96-2.25) and 1.48 (1.07-2.04), respectively]. INTERPRETATION: Severe OSA was associated with increased risk of hospitalizations with pneumonia in this community-based cohort. OSA patients may benefit from more aggressive efforts to prevent pneumonia and other infectious conditions.

Validation of the Modified Berlin Questionnaire for the Diagnosis of Obstructive Sleep Apnea in Patients with a History of COVID-19 Infection.

(1) Background: The Berlin questionnaire (BQ) is a widely used survey to predict obstructive sleep apnea (OSA). Considering the confounding effect of obesity and hypertension on the clinical course of COVID-19, we have recently developed a modified BQ (mBQ) based on the subscales snoring intensity/frequency, witnessed apneas and morning/daytime tiredness, and demonstrated that patients with high-risk OSA had worse outcomes during the COVID-19 pandemic. In the current study, we aimed to validate the mBQ in adults with a history of COVID-19 infection. (2) Method: All cases who suffered from COVID-19 infection between 10 March and 22 June 2020, and who completed the mBQ in our first study, were invited to participate. Participants refilled the questionnaires, and an attended polysomnography (PSG) was conducted. An apnea-hypopnea index (AHI) of 15 events/h or more was considered as OSA. (3) Results: Out of the 70 participants, 27 (39%) were categorized as having a high risk of OSA based on the mBQ. According to the PSG results, 24 patients with high-risk OSA (89%) and 3 patients with low-risk OSA on the mBQ (7%) had AHI ≥ 15 events/h. The mBQ had a sensitivity of 89%, a specificity of 93%, a positive predictive value of 89%, a negative predictive value of 93%, and an accuracy of 91%. The area under the curve was 0.91 confirming a very good performance of the mBQ in screening for OSA. (4) Conclusions: The mBQ has a good level of diagnostic sensitivity, specificity, and accuracy among adults with a history of COVID-19 infection. Since the confounding effects of obesity and hypertension are eliminated, the mBQ may be used not only as a screening tool for high-risk OSA but also as a prognostic survey in clinical cohorts.

Impact of the coronavirus disease-2019 pandemic on Veterans Health Administration Sleep Services.

Objectives: To understand the impact of the coronavirus disease-2019 pandemic on sleep services within the United States Department of Veterans Affairs using separate surveys from "pre-COVID" and pandemic periods. Methods: Data from a pre-pandemic survey (September to November 2019) were combined with data from a pandemic-period survey (August to November 2020) to Veterans Affairs sleep medicine providers about their local sleep services within 140 Veterans Affairs facilities). Results: A total of 67 (47.9%) facilities responded to the pandemic online survey. In-lab diagnostic and titration sleep studies were stopped at 91.1% of facilities during the pandemic; 76.5% of facilities resumed diagnostic studies and 60.8% resumed titration studies by the time of the second survey. Half of the facilities suspended home sleep testing; all facilities resumed these services. In-person positive airway pressure clinics were stopped at 76.3% of facilities; 46.7% resumed these clinics. Video telehealth was either available or in development at 86.6% of facilities and was considered a lasting addition to sleep services. Coronavirus disease-2019 transmission precautions occurred at high rates. Sleep personnel experienced high levels of stress, anxiety, fear, and burnout because of the pandemic and in response to unexpected changes in sleep medicine care delivery. Conclusions: Sleep medicine services within the Veterans Affairs evolved during the pandemic with many key services being interrupted, including in-lab studies and in-person positive airway pressure clinics. Expansion and initiation of telehealth sleep services occurred commonly. The pandemic adversely affected sleep medicine personnel as they sought to maintain access to care.

Diagnosis of Nasal Breathing Using a Rhinomanometer in Patients with Osa Prescribed Conservative Treatment with Intraoral Devices

In recent years, diagnostics in the field of medicine has developed at an extremely rapid pace, thanks to the use and improvement of new medical devices and devices. The problem of timely and adequate diagnosis and treatment of the syndrome of obstructive sleep apnea (OSA) and snoring is particularly relevant world-wide. The disease has been proven to worsen the patients' quality of life, and may even threaten it. Obstructive sleep apnea and snoring syndrome (OSAS) is a widespread disease of social importance in which there is a reduction or cessation of airf low through the nose/mouth during sleep due to upper airway collapse. Obstructive sleep apnea affects the cardiovascular, endocrine, neurocognitive and other systems of the body. There are symptoms of loud snoring, choking, hypoxemia, and micro-awakenings, leading to sleep frag-mentation, daytime fatigue, and sleepiness. The latter greatly worsens the quality of life of patients. There are real risks to the life and health of the patient and others, given the possibility of falling asleep at the wheel in drivers with sleep apnea and participation in traffic accidents. To diagnose the syndrome, a poly-somnographic study is performed, which is still the gold standard. For a better diagnosis, it is recommend-ed to combine it with rhinomanometry. Treatment of OSA includes control of risk factors and removal of obstructive factors that make breathing difficult. Severe OSA syndrome is treated with continuous positive pressure ventilation (CPAP) during sleep, possibly in combination with intraoral devices. Rhinomanome-try can also be used to monitor the effectiveness of CPAP therapy in severe forms of the syndrome by deter-mining tissue resistance. The impact on patients with a milder form of OSA treated with intraoral devices is also monitored. The method can also be used in patients with allergic rhinitis, sinusitis of rhinogenic and other origin, and patients with orthodontic deformities. The correct choice of intraoral appliances for conservative treatment of OSA and timely diagnosis are key to successful treatment.Copyright © 2022, Bulgarian-American Center. All rights reserved.

Covid-19 and Obstructive Sleep Apnea: The Theatricals and Quality-of-Life Impact.

COVID-19 caused by SARS-CoV2 has reached pandemic proportions. The fear of Covid-19 has deterred many to abandon efforts for seeking timely medical help. In this setting, Obstructive sleep apnea (OSA)-like covid/non-covid cohorts have presented. Atypical pathologies can present like OSA and take the clinician unawares. With this series of misfits suffering silently, it would be unwise to underestimate its impact on quality-of-life (QOL). To determine the effect on quality-of-life by pathologies mimicking OSA and assess Covid-19 as a cause for delayed presentation. This was a prospective cross-sectional study. 127(N). Recent onset of symptoms of OSA. Study duration March 2020 to September 2021. Pittsburgh Sleep Quality Index (PSQI) screening done. Study criteria defined. Sleep parameters calculated. Primary surgical intervention given. Non-responders were put on CPAP therapy. QOL assessment done with sf-36 and SAQLI. Fear of Covid-19 scale (FCV-19S) quantified to study cause for temporal delay. Correlations computed. Level of Evidence-Level 3. 97 candidates completed study. Demographic and anthropometric details noted. Mean range was 43.85 ± 11.39 years. Male predominance. Overall AHI-19.73 ± 8.72. Moderate impact on QOL by sf-36/SAQLI. 78n Primary surgical candidates fared well. Polysomnography (PSG) and Continuous positive airway pressure (CPAP) titration/trial characteristics for 19n available. Statistically significant improvement in QOL after treatment completion. Correlations were meaningful. Body Mass Index (BMI) as a single factor was not influential on OSA-mimickers. Fear of Covid-19 significantly impacted emergency medical aid acquisition. OSA mimicking atypical airway pathologies may need emergent treatment not only from a surgical point-of-view but also from the QOL of the patient. On the contrary, these also unmask sub-clinical OSA, especially in patients with low/normal BMI. This category of recent onset OSA, if fortunately picked up at the earliest possible presentation, may hopefully not go through the significant QOL impact suffered by chronic OSA candidates.

Sleep disorders and COVID-19.

This chapter summarizes the known associations between COVID-19 and sleep dysfunction, including insomnia, excessive daytime sleepiness, restless legs syndrome and nightmares, and touches upon pandemic-related considerations for obstructive sleep apnea and continuous positive airway pressure treatment. Treatment strategies and management approaches are also briefly discussed.

MoCA-T as a remote assessment tool to determine cognitive impairment in patients with moderate to severe OSA

The COVID-19 pandemic has led to the emergence of technological tools that allow remote assessment on patients. The Montreal Cognitive Assessment Test Telephone Version (MoCA-T) is one of them. Considered as a telemedicine resource that allows remote cognitive screening in pandemic era and in the population with difficulties in accessing health centers. Mild cognitive impairment (MCI) is a common finding in patients with Obstructive Sleep Apnea Hypopnea Syndrome (OSAHS). However, the application of telephone tests for cognitive screening has not been studied. To determine the frequency of cognitive deterioration through the application of MoCA-T as a remote screening test in patients with moderate and severe OSAHS is the main objective of this work. To do this, the MoCA-T test was applied to 104 patients with polysomnographic diagnostic capabilities for moderate and severe OSAHS between ages 18 and 65, excluding patients with comorbidities that affect cognitive ones. Abnormal MoCA-T results were obtained in 43% of patients, with the cognitive domains of memory and attention being the most affected. Finally, abnormal MoCA-T results correlated with self-perception of memory difficulties, being more frequently altered in those who manifest cognitive complaints. The MoCA-T test could be a brief, validated and feasible technological tool for cognitive screening of patients with OSAHS in times of pandemic and in patients with care barriers.Copyright © 2023 Sociedad Neurologica Argentina

Feasibility of Same-Day Discharge After Laparoscopic Roux-en-Y Gastric Bypass in Patients with Well-Regulated Obstructive Sleep Apnea.

INTRODUCTION: Same-day discharge after bariatric surgery is increasingly being performed. In current practice, patients with only minor comorbidities are considered eligible for same-day discharge after laparoscopic Roux-en-Y gastric bypass (RYGB). Obstructive sleep apnea (OSA) is a common comorbidity in patients with morbid obesity, with a prevalence of around 70-80% among patients undergoing bariatric surgery. Continuous positive airway pressure (CPAP) is the current gold standard treatment for OSA. We aimed to investigate whether same-day discharge after RYGB is feasible for patients with compliant use of CPAP. METHODS: In this single-center prospective feasibility study, patients were selected who were scheduled for RYGB and were adequately treated for OSA. Compliance on the use of CPAP had to be proved (> 4 h per night for 14 consecutive nights). There were strict criteria on approval upon same-day discharge. The primary outcome was the rate of successful same-day discharge. Secondary outcomes included short-term complications, emergency department presentations, readmissions, and mortality. RESULTS: Forty-nine patients underwent RYGB with intended same-day discharge, of whom 45 (92%) were successfully discharged. Three patients had an overnight stay because of divergent vital signs and one patient due to a delayed start of the surgery. Two patients (4%) were readmitted in the first 48 h postoperatively, both due to intraluminal bleeding which was managed conservatively (Clavien-Dindo 2). There were no severe complications in the first 48 h after surgery. CONCLUSION: Same-day discharge after RYGB can be considered feasible for selected patients with well-regulated OSA.

The Management of Obstructive Sleep Apnea Patients during the COVID-19 Pandemic as a Public Health Problem-Interactions with Sleep Efficacy and Mental Health.

With the onset of the COVID-19 outbreak, it was stipulated that patients with obstructive sleep apnea (OSA) may have a greater risk of morbidity and mortality and may even experience changes in their mental health. The aim of the current study is to evaluate how patients managed their disease (sleep apnea) during the COVID-19 pandemic, to determine if continuous positive airway pressure (CPAP) usage changed after the beginning of the pandemic, to compare the stress level with the baseline, and to observe if any modifications are related to their individual characteristics. The present studies highlight the level of anxiety, which was high among patients with OSA during the COVID-19 pandemic (p < 0.05), with its influence on weight control (62.5% of patients with high levels of stress gained weight) and sleep schedule (82.6% reported a change in sleep schedule). Patients with severe OSA and high levels of stress increased their CPAP usage (354.5 min/night vs. 399.5 min/night during the pandemic, p < 0.05). To conclude, in OSA patients, the presence of the pandemic led to a greater level of anxiety, changes in sleep schedule and weight gain because of job loss, isolation, and emotional changes, influencing mental health. A possible solution, telemedicine, could become a cornerstone in the management of these patients.

Impact of mail-based continuous positive airway pressure initiation on treatment usage and effectiveness.

PURPOSE: In-person visits with a trained therapist have been standard care for patients initiating continuous positive airway pressure (CPAP). These visits provide an opportunity for hands-on training and an in-person assessment of mask fit. However, to improve access, many health systems are shifting to remote CPAP initiation with equipment mailed to patients. While there are potential benefits of a mailed approach, relative patient outcomes are unclear. Specifically, many have concerns that a lack of in-person training may contribute to reduced CPAP adherence. To inform this knowledge gap, we aimed to compare treatment usage after in-person or mailed CPAP initiation. METHODS: Our medical center shifted from in-person to mailed CPAP dispensation in March 2020 during the COVID-19 pandemic. We assembled a cohort of patients with newly diagnosed obstructive sleep apnea (OSA) who initiated CPAP in the months before (n = 433) and after (n = 186) this shift. We compared 90-day adherence between groups. RESULTS: Mean nightly PAP usage was modest in both groups (in-person 145.2, mailed 140.6 min/night). We did not detect between-group differences in either unadjusted or adjusted analyses (adjusted difference - 0.2 min/night, 95% - 27.0 to + 26.5). CONCLUSIONS: Mail-based systems of CPAP initiation may be able to improve access without reducing CPAP usage. Future work should consider the impact of mailed CPAP on patient-reported outcomes and the impact of different remote setup strategies.

Sleep Disorders in Patients after COVID-19.

Healthy sleep is required to ensure the body's homeostatic stability, the consistency of immunological reactions, and optimum functioning of the internal organs, the nervous system, and cognitive functions. Patterns of changes to the circadian rhythms have been studied in many diseases, though infection with SARS-CoV-2 is a new reality and the basic mechanisms of functioning of the body in this pathology require deeper investigation. Despite the difficulty of analytical investigations in pandemic conditions, experience of the diagnosis of COVID-19 has now been acquired and treatment algorithms have been developed for different clinical situations; vaccines have been developed. Least studied are questions of the long-term sequelae of COVID-19. At the same time, there are good grounds for suggesting that patients need long-term rehabilitation in the post-covid period of SARS-CoV-2, for reasons including damage to the nervous system. Analysis of publications - from descriptions of clinical cases to literature reviews - allows empirical experience to be accumulated, providing the opportunity for future identification of prognostic markers for the disease for effective prevention of long-term sequelae. The results of current prospective studies draw attention to the occurrence of dyssomnia and obstructive sleep apnea not only as a common consequence of coronavirus infection, but also as a factor significantly worsening the prognosis in the acute period of illness. It has repeatedly been shown that sleep deprivation has adverse influences on the body's resistance, including to SARS-CoV-2, and requires correction to improve prognoses in the acute and long-term periods of illness in COVID-19 patients.

Post COVID-19 pulmonary complications in outpatient setting: Insights from a cross-sectional study in a rural academic hospital.

OBJECTIVE: Post COVID-19 disease pulmonary complications are generally expected among the hospitalized or elderly patients with multiple comorbidities given the gravity of the disease among such patients. However, non-hospitalized patients with less severe symptoms from COVID-19 disease have also been experiencing significant morbidity and difficulty functioning their activities of daily living. Therefore, we aim to characterize post COVID-19 pulmonary complications (symptomatology, clinical and radiological findings) in patients who did not require hospitalization but had significant outpatient visits secondary to COVID-19 sequelae. METHODS: This is a two part cross-sectional study based on a retrospective chart review. Patients with COVID-19 disease not requiring hospitalization but followed up at pulmonology clinic with respiratory symptoms were analyzed twice in an interval of 12 months. 23 patients in first cross-section group (followed up from December 2019 to June 2021) and 53 patients in second group (followed up from June 2021 to July 2022) were included in the analyses. Differences in mean and percentage of baseline characteristics and clinical outcomes between the two groups are analyzed using unpaired t-tests and Chi-squared tests respectively. Post COVID-19 disease symptoms are classified in to 3 different groups (mild, moderate and severe) based on duration of symptoms and presence or absence of hypoxia. RESULTS: Dyspnea on exertion (DOE) was the common compliant in majority of patients in both cross-section groups (43.5% vs 56.6%). Mean age in years were 33 and 50 in first and second cross-section groups respectively. Majority of the patients had mild and moderate symptoms in both groups (43.5% vs 9.4%, P = 0.0007; 43.5% vs 83%, P = 0.005). Mean duration of symptoms in first cross-section group was 3.8 whereas 10.5 months (P = 0.0001) in second cross-section group. CONCLUSION: Our study outlines the burden of post COVID-19 disease pulmonary complications in patient group where these complications are less expected. Strategies for the implementation of multidisciplinary post COVID-19 care clinic along with mass vaccination awareness campaigns in rural US should be prioritized to mitigate this existing burden.

MoCA-T como herramienta de evaluación remota para precisar deterioro cognitivo en pacientes con SAHOS moderado a severo

Resumen La pandemia de COVID-19 ha dado lugar al surgimiento de herramientas tecnológicas que permiten la valoración de pacientes de forma remota. La prueba de evaluación cognitiva de Montreal, versión telefónica (MoCA-T), es una de ellas. Se considera como un recurso de la telemedicina que permite la tamización cognitiva a distancia en épocas de pandemia y en la población con dificultades en el acceso a los centros de salud. El deterioro cognitivo leve (DCL) es un hallazgo usual en pacientes con síndrome de apnea-hipopnea obstructiva del sueño (SAHOS);sin embargo, no se ha estudiado la aplicación de pruebas telefónicas para su tamización cognitiva. El objetivo principal de este trabajo es determinar la frecuencia de deterioro cognoscitivo mediante la aplicación de MoCA-T como prueba de tamización remota en pacientes con SAHOS moderado y severo. Para ello, se aplicó la prueba de MoCA-T en 104 pacientes entre 18 y 65 años con diagnóstico polisomnográfico de SAHOS moderado y severo, excluyéndose a pacientes con comorbilidades que afectasen las capacidades cognoscitivas. Se obtuvieron resultados anormales de MoCA-T en el 43% de los pacientes, siendo los dominios cognitivos de la memoria y la atención los más comúnmente afectados. Finalmente, los resultados anormales de MoCA-T se correlacionaron con la autopercepción de las dificultades en la memoria, estando más frecuentemente alterada en quienes manifestaron quejas cognitivas. La prueba MoCA-T podría ser una herramienta tecnológica breve, validada y factible para realizar el tamizaje cognitivo de pacientes con SAHOS en épocas de pandemia y en pacientes con barreras asistenciales.

[Management of Obstructive Sleep Apnea Syndrome during the Coronavirus Disease 2019 Pandemic].

The coronavirus disease 2019(COVID-19) pandemic poses a severe threat to global health.As an emerging infectious disease mainly attacking the respiratory tract,it has severely challenged the management of chronic non-infectious respiratory diseases including obstructive sleep apnea(OSA) and asthma.This article reviews the impact of OSA on the incidence of COVID-19 and the underlying pathophysiological mechanism,as well as the effects of OSA on the hospitalization risk and the prognosis and outcome of COVID-19 patients,which will provide novel ideas for the management of OSA during the COVID-19 pandemic.

Causal associations between obstructive sleep apnea and COVID-19: A bidirectional Mendelian randomization study.

BACKGROUNDS: The COVID-19 pandemic has caused significant impact on human health. Whether obstructive sleep apnea (OSA) increases the risk of COVID-19 remains unclear. We sought to clarify this issue using two-sample Mendelian randomization (TSMR) analysis in large cohorts. METHODS: Bidirectional two-sample Mendelian randomization (MR) was used to evaluate the potential causality between OSA and COVID-19 by selecting single-nucleotide polymorphisms (SNPs) as instrumental variables (IVs) from genome-wide association studies (GWAS). The inverse-variance weighted (IVW) method was selected as the main approach for data analysis to estimate the possible causal effects. Alternative methods such as MR-Egger, the MR pleiotropy residual sum and outlier (MR-PRESSO), and leave-one-out analysis methods were implemented as sensitivity analysis approaches to ensure the robustness of the results. RESULTS: All forward MR analyses consistently indicated the absence of a causal relationship between OSA and any COVID-19 phenotype. In the reverse MR analysis, the IVW mode demonstrated that severe respiratory confirmed COVID-19 was correlated with a 4.9% higher risk of OSA (OR, 1.049; 95%CI, 1.018-1.081; P = 0.002), consistent in MR-PRESSO (OR = 1.049, 95%CI 1.018-1.081, P = 0.004), weighted median (OR = 1.048, 95%CI 1.003-1.095, P = 0.035), and MR-Egger (OR = 1.083, 95%CI 1.012-1.190, P = 0.041) methods. CONCLUSIONS: There is no significant evidence supporting a causal association between OSA and any COVID phenotype, while we identified potential evidence for a causal effect of severe COVID-19 on an increased risk of OSA.
