Factors Associated with the Efficiency of Home Non-Invasive Ventilation in Patients with Obesity-Hypoventilation Syndrome in Martinique

Obesity-hypoventilation syndrome (OHS) is a respiratory complication of obesity characterized by chronic hypercapnic respiratory failure. It is often associated with several comorbidities and is treated by positive airway pressure (PAP) therapy. This study aimed to identify factors associated with persistent hypercapnia in patients receiving home non-invasive ventilation (NIV). We performed a retrospective study including patients with documented OHS. In total, 143 patients were included (79.7% women, age 67 ± 15.5 years, body mass index 41.6 ± 8.3 kg/m²). After 4.6 ± 4.0 years of follow-up, 72 patients (50.3%) remained hypercapnic. In bivariable analysis, clinical data showed no difference in follow-up duration, number of comorbidities, comorbidities, or circumstance of discovery. Patients with persistent hypercapnia on NIV were generally older, with lower BMI and more comorbidities. (5.5 ± 1.8 versus 4.4 ± 2.1, p = 0.001), female sex (87.5% versus 71.8%), was treated by NIV (100% versus 90.1%, p < 0.01), had lower FVC (56.7 ± 17.2 versus 63.6 ± 18% of theoretical value, p = 0.04), lower TLC (69.1 ± 15.3 versus 74.5 ± 14.6% of theoretical value, p = 0.07), lower RV (88.4 ± 27.1 versus 102.5 ± 29.4% of theoretical value, p = 0.02), higher pCO2 at diagnosis (59.7 ± 11.7 versus 54.6 ± 10.1 mmHg, p = 0.01) and lower pH (7.38 ± 0.03 versus 7.40 ± 0.04, p = 0.007), higher pressure support (12.6 ± 2.6 versus 11.5 ± 2.4 cmH₂O, p = 0.04) and lower EPAP (8.2 ± 1.9 versus 9 ± 2.0 cmH₂O, p = 0.06). There was no difference in non-intentional leaks and daily use between patients between both groups. By multivariable analysis, sex, BMI, pCO2 at diagnosis, and TLC were independent risk factors for persistent hypercapnia on home NIV. In individuals with OHS, persistent hypercapnia on home NIV therapy is frequent. Sex, BMI, pCO2 at diagnosis, and TLC were all associated with an increased risk of persistent hypercapnia in persons treated with home NIV.

Prevalence, treatment and determinants of obstructive sleep apnoea and its symptoms in a population-based French cohort

Background

Obstructive sleep apnoea (OSA) is associated with increased morbidity and mortality. Although the disorder has been well studied in selected high-risk populations, few data exist on its prevalence in the general population. We aimed to assess the prevalence and determinants of OSA in France.

Methods

Data from participants of the French population-based CONSTANCES cohort aged 18-69 years at inclusion and being treated for sleep apnoea or screened for OSA in 2017 using the Berlin Questionnaire were analysed. Weighted analyses were performed to provide recent and representative results in the general population.

Results

Among 20 151 participants, the prevalence of treated sleep apnoea was 3.5% (95% CI 3.0-3.9%). The prevalence of untreated subjects with a positive Berlin Questionnaire was 18.1% (95% CI 17.3-19.2%) for a total weighted prevalence of treated sleep apnoea or high risk of OSA of 20.9% (95% CI 20.0-21.9%). Regarding prevalence of OSA symptoms, it was 37.2% (95% CI 36.1-38.3%) for severe snoring and 14.6% (95% CI 13.8-15.5%) for hypersomnolence. In multivariable logistic regression analysis, male sex, age, previous cardiovascular events, smoking, low educational level, low physical activity and depressive symptoms were associated with having either treated sleep apnoea or a positive Berlin Questionnaire.

Conclusion

In this large French population-based cohort, one in five participants had a high likelihood of OSA, whereas only 3.5% were treated for the disorder, suggesting major underdiagnosis in the general population. OSA diagnosis should be considered more often in people with risk factors such as depressive symptoms as well as unhealthy behaviours and socioeconomic conditions.

[Sleep disorders and psycho-affective problems in paramedical personnel working an atypical schedule]

INTRODUCTION

Shift work can cause health problems and sleep disorders and therefore affect mental health. These psycho-affective disorders can, in return, worsen sleep disorders and thus establish a vicious circle. The aims of our study were to assess the frequency of sleep and psycho-affective disorders among paramedical personnel doing shift work and to screen them for obstructive sleep apnoea-hypopnoea syndrome (OSA).

METHODS

It was a cross-sectional study carried out among paramedical staff at the University Hospital Center Mongi Slim La Marsa in Tunis. Three questionnaires translated into Arabic (the Berlin questionnaire, the Spiegel questionnaire and the Hospital Anxiety and Depression Scale [HAD]) were presented by the same investigator during the survey.

RESULTS

One hundred and fifty-eight paramedics were interviewed (46.2% were nurses, 23.4% were blue-collar workers, 19% were senior technicians and 11.4% were health care aides, midwives and physiotherapists). The average duration of shift work was 10.27 years, the average age was 36.48 years and there was a female prevalence of 70.9%. Sleep disorders were detected in 40.5% of the cases, OSA in 24%, anxiety in 53.2% and depression in 17.1%.

CONCLUSION

Sleep and psycho-affective disorders are frequent among paramedical personnel undertaking shift work in hospitals. Screening consultations in occupational medicine are necessary in order to detect these disorders at an early stage.

Prevalence and risk factors of people at-risk of obstructive sleep apnea in a rural community of Odisha, India: a community based cross-sectional study

BACKGROUND

Obstructive sleep apnea (OSA) is a progressive sleep disordered breathing condition characterized by repeated episodes of upper airway collapse during sleep. Despite being the most common sleep apnea, it often remains undiagnosed and untreated, especially in rural communities. There is a paucity of literature estimating the prevalence of the disease and associated risk factors from the rural population of Odisha.

METHODS

It is a cross-sectional study that was conducted in a rural community of Odisha, India to find out the prevalence of people living with the risk of OSA. Multi-staged sampling was done. Participants were evaluated using the Berlin questionnaire (BQ) after obtaining informed consent. Data were analyzed using SPSS with the significance level set at 95%. Univariate and multivariate analysis was done to evaluate the risk factors associated with the condition.

RESULTS

Out of 200 community dwellers surveyed using the BQ, 25% had a high likelihood of OSA. Among these high risk subjects, snoring was reported by 70%, excessive daytime sleepiness by 50%. Out of those who were at risk of OSA, 28% were smokers and 48% reported alcohol use. The associated risk factors were age >35 years (OR = 4.5, 95% CI = 1.4-13.8, p < 0.05), BMI ≥ 25 kg/m² (aOR = 3.5, 95% CI = 1.2- 10.5, p < 0.05), alcoholism (aOR = 4.5, 95% CI = 1.8-11.1, p = 0.001), and hypertension (aOR = 11.5, 95% CI = 4.7-28, p < 0.001). The prevalence was not affected by the type of diet (vegetarian vs non-vegetarian), use of tobacco or tea consumption.

CONCLUSION

OSA is highly prevalent in the rural community of Odisha. Independent risk factors associated with such subjects were obesity, regular alcohol consumption, and hypertension. Further prevalence studies are recommended.
