ABSTRACT
BACKGROUND: Several studies evaluated the effect of bariatric surgery on obstructive sleep apnea (OSA) but findings have been inconsistent. The aim of this study was to conduct an updated systematic review and meta-analysis to investigate the effect of bariatric surgery on OSA. METHODS: The databases for PubMed, CENTRAL, and Scopus were searched up to the 1st of December, 2021. Studies were included if they were cohort or case-control in design, included patients with diagnosis of OSA, the patients underwent any bariatric surgery, and the study performed postoperative polysomnography. RESULTS: The total number of the included patients was 2310 patients with OSA from 32 studies. Our analysis showed that bariatric surgery was associated with significant reduction in BMI (WMD = - 11.9, 95%CI: - 13.4, - 10.4), apnea-hypopnea index (AHI) (WMD = - 19.3, 95%CI: - 23.9, - 14.6), and respiratory disturbance index (RDI) (WMD = - 33.9, 95%CI: - 42.1, - 25.7). The rate of OSA remission after the surgery was 65% (95%CI: 0.54, 0.76). CONCLUSION: Our results suggest that bariatric surgeries are effective in reducing obesity among patients with OSA in addition to OSA severity measures. However, the low rate of OSA remission suggests that the main etiology of OSA is not only obesity but also includes other important variables such as the anatomy of the jaw.

OBJECTIVE: The COVID-19 pandemic led to a deviation from classical face-to-face learning to distance learning. Few studies examined burnout among university students during the distance learning period due to the COVID-19 pandemic. This study that aims to investigate the prevalence of burnout among university students during distance learning and the factors associated with it. METHOD: A cross-sectional study was conducted among undergraduate students at the University of Jordan. The modified version of the Maslach Burnout Inventory for students (MBI-SS) was used to assess burnout. RESULTS: The total number of participants was 587 and the mean total of MBI-SS score was 63.34 ± 8.85. Based on the MBI-SS definition, 6.6% of the study participants were found to have symptoms of burnout. Practicing hobbies, level of satisfaction with distance learning, and thoughts about quitting courses were significant predictors of burnout. CONCLUSION: This study showed a relatively low prevalence of burnout among students during the distance learning period with several factors associated with it. As a result, identifying these factors will help both students and educational institutions to implement strategies that are needed for the primary and secondary prevention of burnout.

INTRODUCTION: This review aimed to assess the risk factors of Obstructive Sleep Apnea (OSA) in pediatric children, a common condition with serious long-term sequela. METHODS: PubMed, CENTRAL, Scopus, and Google Scholar were searched using the keywords "Apnea", "Obstructive Sleep" OR "Obstructive Sleep Apnea Syndrome" AND "Child" OR "Children" OR "Pediatrics". Data from 35 studies involving 497,688 pediatric patients diagnosed with OSA using polysomnography were reviewed. Risk factors examined included sex, obesity, neck circumference, tonsillar/adenoid hypertrophy, respiratory infections, nasal stenosis, parental OSA/smoking, ethnicity, preterm birth, and breastfeeding history. Relative Risk (RR) with 95% Confidence Intervals (95% CI) were calculated, using Cochrane Q and I² statistics to estimate heterogeneity. RESULTS: Tonsillar hypertrophy (RR = 3.55), adenoid hypertrophy (RR = 1.63), respiratory tract infection (RR = 2.59), obesity (RR = 1.74), and family history of OSA (RR = 3.03) were significantly associated with pediatric OSA. White ethnicity was protective (RR = 0.77). DISCUSSION: Recognizing these risk factors aids in early diagnosis and treatment of pediatric OSA.
ABSTRACT
Several definitions were proposed to diagnose Positional Obstructive Sleep Apnea (pOSA). However, the comparison between these definitions according to their diagnostic value is scarce in the literature. Thus, we decided to conduct this study to compare between the four criteria according to their diagnostic value. Between 2016 and 2022, 1092 sleep studies were performed at the sleep lab at the Jordan University Hospital. Patients who had an AHI <5 were excluded. pOSA was described according to the four definitions; Amsterdam Positional OSA Classification (APOC), supine AHI twice the non-supine AHI (Cartwright), Cartwright plus the non-supine AHI <5 (Mador), and overall AHI severity at least 1.4 times the non-supine severity (Overall/NS-AHI). Furthermore, 1033 polysomnographic sleep studies were retrospectively analyzed. The prevalence of pOSA according to the reference rule was 49.9% among our sample. The Overall/Non-Supine definition had the highest sensitivity, specificity, positive predictive value, and negative predictive value, which were 83.5%, 99.81%, 99.77%, and 85.88% respectively. The Overall/Non-Supine definition also had the highest accuracy among the four definitions (91.68%). Our study showed that all the criteria had a diagnostic accuracy above 50%, indicating that they were accurate in forming the diagnosis of pOSA. The Overall/Non-Supine criteria had the highest sensitivity, specificity, diagnostic odds ratio, and positive likelihood ratio as well as the lowest negative likelihood ratio, indicating the superiority of this criterion over the other definitions. Choosing the right criteria for diagnosing pOSA would result in fewer patients being assigned to CPAP and more being assigned to positional therapy methods.

COVID-19 is a public health crisis that has caused numerous deaths, necessitated an increased number of hospital admissions, and led to extended inpatient stays. This study aimed to identify the factors associated with COVID-19 mortality, intensive care unit admission, intubation, and length of hospital stay among Jordanian patients. This was a one-year retrospective study of 745 COVID-19 patients admitted to Jordan University Hospital. Data regarding the patients' demographics, clinical and co-morbid conditions, imaging, laboratory parameters, mortality, intensive care unit admission (ICU), and intubation were collected from their medical records using a coding manual. The data revealed that the overall rates of COVID-19-related mortality, ICU admission, and invasive intubation were 23.0%, 28.3%, and 10.8%, respectively. Chronic kidney disease (CKD), troponin, lactate dehydrogenase (LDH), and O2 saturation <90% were significantly associated with the mortality rate. The variables that were significantly associated with ICU admission were heart failure and the use of remdesivir. However, O2 saturation <90% and gastrointestinal (GI) symptoms were the only variables associated with invasive intubation. The findings of this study suggest that study-related health outcomes can be used to predict the severity of COVID-19, and they can inform future research aiming to identify specific populations who are at a higher risk of COVID-19 complications.
ABSTRACT
The aim of this study was to assess postacute coronavirus disease 2019 (COVID-19) syndrome (PACS) symptoms according to the onset of the infection while evaluating the effect of COVID-19 vaccination on the symptoms of PACS. We conducted a retrospective single-center cohort study in which nonhospitalized COVID-19 survivors and healthy controls were compared for the occurrence of PACS. The total number of patients in this study was 472. At 6-12 and > 12 months after the infection, COVID-19 survivors had a significantly higher incidence of posttraumatic stress disorder (PTSD) and anxiety than the non-COVID-19 cohort. Furthermore, depression, cognitive deficit, tics, impaired quality of life and general health impairment were significantly more prevalent among COVID-19 survivors at < 6 months, 6-12 months and > 12 months than in the non-COVID-19 cohort. However, respiratory symptoms were significantly more prevalent among COVID-19 survivors only in the first 6 months after infection. In addition, cognitive deficit (OR = 0.15; 95% CI 0.03-0.87) and impaired quality of life (B = - 2.11; 95% CI - 4.21 to - 0.20) were significantly less prevalent among vaccinated COVID-19 survivors than among nonvaccinated survivors. Longitudinal studies are needed to establish the time that should elapse after COVID-19 infection for the symptoms of PACS to appear. Randomized clinical trials are needed to assess the possibility that COVID-19 vaccines might relieve PACS symptoms.

BACKGROUND: Obstructive sleep apnea (OSA) is a common cause of sleep-disordered breathing with a large proportion of the patients exhibiting positional OSA (POSA). In this study, we aimed to evaluate the differences in the demographics, comorbidities, and polysomnographic features between POSA and non-POSA (NPOSA) in a Jordanian sample to further discern the propulsive elements for each group. METHODS: In this study, we evaluated 1037 adult patients with OSA. POSA was defined as an overall apnea and hypopnea index (AHI) >5, an overall AHI severity at least 1.4 times the nonsupine severity (overall/NS-AHI), and a minimum amount of time (i.e., 20 min) in the supine and nonsupine positions. To compare the clinical characteristics between POSA and NPOSA patients, statistical analyses were performed. RESULTS: The prevalence of POSA was 41.7%. In comparison to NPOSA patients, POSA patients had higher female sex prevalence, milder OSA, lower body mass index, lower hypertension prevalence, and lower hemoglobin A1C levels compared to NPOSA patients. Moreover, sleep efficiency, total sleep time, and supine sleep time were significantly higher in POSA patients. Nonsupine sleep time, total AHI, rapid eye movement (REM) AHI, non-REM (NREM) AHI, supine AHI, nonsupine AHI, left and right AHI, mean oxyhemoglobin saturation (SpO2) awake, mean REM and NREM SpO2, SpO2 nadir, and time SpO2 below 90% were significantly lower among POSA patients. The multivariate regression analysis showed that only female gender and hypertension were significantly associated with POSA. CONCLUSION: POSA is common among OSA patients and demonstrates different clinical characteristics in comparison to NPOSA. Future prospective studies are needed to better characterize the POSA patients and investigate the benefit of positional therapy.
