Introduction: Obesity-hypoventilation syndrome occurs with alveolar hypoventilation during sleeping and daytime. Obesity may be a risk factor for venous thromboembolism. However, the venous thromboembolism in the obesity-hypoventilation syndrome is not well characterized.
Objective: This case series aimed to investigate the presence and clinical features of venous thromboembolism in patients with the obesity-hypoventilation syndrome.
Methods: Data of eight case reports were collected. Ages ranged from 36 to 73 years.
Results: All patients had mosaic perfusion and enlarged main pulmonary artery, two had signs of infarction and mostly segmental and subsegmental filling defects. On the basis of this information some conclusions can be drawn carefully.
Conclusion: Present cases indicate that pulmonary embolism are also very common in patients with obesity-hypoventilation syndrome, anticoagulant therapy is at least as important as the treatment of the current disease. Clinicians will frequently be faced with patients with obesity-hypoventilation syndrome suspected of PE.

Central and Obstructive Sleep Apnea (CSA and OSA), Chronic Obstructive Pulmonary Disease (COPD), and Obesity Hypoventilation Syndrome (OHS) disrupt breathing patterns, posing significant health risks and reducing the quality of life. Bilevel Positive Airway Pressure (BiPAP) therapy offers adjustable inhalation and exhalation pressures, potentially enhancing treatment adaptability for the above diseases. This is the first-ever study that employs Computational Fluid Dynamics (CFD) to examine the biomechanical impacts of BiPAP under four settings: Inspiratory Positive Airway Pressure (IPAP)/Expiratory Positive Airway Pressure (EPAP) of 12/8, 16/6, and 18/8 cmHO, compared to a without-BiPAP scenario of zero-gauge pressure.

Introduction: Osteogenesis Imperfecta (OI) is characterised by brittle bones, severe skeletal deformities, low sleep quality, and restricted breathing. We aimed to distinguish how disease and obesity affect these results.
Methods: According to BMI, we considered four groups of peer adults (median age: 35.

Background: Studies on the survival of patients with home mechanical ventilation (HMV) are sparse. We aimed to analyse the impact of controlled hypercapnia on survival over 27 years among patients with HMV in Sweden.
Study Design And Methods: Population-based cohort study of adult patients starting HMV in the Swedish Registry for Respiratory Failure (Swedevox) during 1996-2022 cross-linked with the National Cause of Death registry.
Chronic Hypercapnic Respiratory Failure in a Patient With Smith-Magenis Syndrome: A Case Report.

Smith-Magenis syndrome (SMS) is a genetic disorder characterized by intellectual disability, behavioral challenges, and distinctive physical abnormalities. This case report describes a patient with SMS who presented with pneumonia and was found to have chronic hypercapnic respiratory failure, attributed to kyphoscoliosis and obesity-related conditions such as obesity hypoventilation syndrome and obstructive sleep apnea. Following treatment with non-invasive ventilation (NIV), the patient's baseline oxygen levels improved, and she was discharged with domiciliary NIV and respiratory follow-up.
