“…That observation that BMI was the most significant predictor of DSD was not surprising as almost all studies supported this finding (Davies and Stradling, 1990;Shinohara et al, 1997;Young et al, 2005;Shneerson, 2012). This study confirms the finding that BMI was the most significant predictor of DSD and also demonstrated a dose-response relationship confirming most previous studies (Arias et al, 2005;Leinum CJ, 2009).…”

Background and purpose:We determined the prevalence of physician-diagnosed sleep disorder and its association with tobacco smoke exposure and vitamin D deficiency.MethodsThe National Health and Nutrition Examination Survey (NHANES) of 2011–2012 data base was used for the study. Subjects were asked two questions: “Ever told your doctor you had trouble sleeping?” and “Ever told by doctor have sleep disorder?” The answer “yes” to the second question indicated presence of a doctor-diagnosed sleep disorder (DSD) and “no” indicated its absence. Tobacco smoke exposure was defined by serum cotinine levels while vitamin D levels were measured by serum 25(OH) D. Eight selected variables included in the analyses were BMI, age, gender, smoking exposure, vitamin D levels, income, insurance, and race. Univariate and multivariate analyses were conducted to determine if tobacco smoke exposure and Vitamin D were each predictive of DSD.ResultsOf 5,470 subjected aged 16 to 80+ years about 9% had doctor-diagnosed sleep disorder (DSD). In a multiple regression analysis, active tobacco smoking was predictive of DSD (OR 1.92; 95% CI = 1.38–2.69), while passive smoke exposure was not, even after controlling for all the other significant variables (OR 0.93; 95% CI = 0.57–1.52). The other variables significantly associated with DSD were by order of importance BMI (P < 0.001), Age (P < 0.001) and race (P ≤ 0.001). Vitamin D deficiency was not predictive of DSD.ConclusionThe prevalence of physician-diagnosed DSD was about 9%. Active smoking but not passive smoking as defined by cotinine levels was significantly associated with DSD. Vitamin D was not predictive of DSD. Future studies are therefore needed to demonstrate whether smoking cessation could help reduce DSD.

“…This apparently put the entire cohort in overweight/obese category [ 43 ] but individually there was a mix of normal, overweight and obese categories. This value was supported by studies [ 44 , 45 ] where the mean neck circumference was 39.2 ± 4.7 cms, 42 cms (median) with range 35–50 cms for OSA patients. This showed a modest variation of 2–4 cms between studies.…”

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.

“…In our study, the absence of pleural contact was the most significant risk factor associated with the occurrence of post-TTLB pneumothorax. These data were corroborated by another retrospective study of Khan et al 3 in which lesions in the lung parenchyma had a higher pneumothorax rate than lesions located in the pleura or thoracic wall. Another significant risk factor identified was lesion size.…”
