Introduction: Obstructive sleep apnea (OSA) is associated with an increased risk of hypertension, coronary artery disease, heart failure (HF), and atrial fibrillation (AF).

Materials And Methods: A total of 179 patients aged 34-81 years were included in the study. The median age was 63 years (interquartile range: 56-69 years). Of these patients, 105 (58.7%) were men, and 74 (41.3%) were women; there were cases of paroxysmal ( = 99), persistent (n = 64), and permanent AF ( = 16). All patients underwent investigations including respiratory sleep monitoring, echocardiography, and 24 h Holter electrocardiography monitoring. Statistical analyses were performed using IBM SPSS Statistics 26.0.

Results: OSA was detected in 131 (73.2%) patients. In patients with OSA, paroxysmal AF was commonest ( = 65), followed by persistent AF ( = 51) and permanent AF ( = 15). The patients with sleep apnea had increased body mass index (33.6 kg/m2; = 0.02), waist circumference (114 cm; < 0.001), and neck circumference (42 cm; < 0.001) values. HF (OR 2.9; 95% CI: 1.4-5.9; = 0.004) and type 2 diabetes (OR 3.6; 95% CI: 1.5-8.3; = 0.001) were more common in patients with AF and OSA. The STOP-BANG scale (AUC = 0.706 ± 0.044; 95% CI: 0.619-0.792; < 0.001) and the Berlin questionnaire (AUC = 0.699 ± 0.044; 95% CI: 0.614-0.785) had a higher predictive ability for identifying sleep apnea.

Conclusions: Patients with AF demonstrate a high prevalence of OSA and an increased association with cardiovascular comorbidities. The STOP-BANG scale and the Berlin questionnaire can be used to screen for OSA in patients with AF.

Sleep apnea (SA) is a sleep disorder characterized by frequent interruptions in breathing during sleep and is widely recognized as a significant global public health concern. Although genome-wide association studies (GWAS) have identified several loci associated with SA susceptibility, the underlying genes and biological mechanisms remain largely unknown. A cross-tissue transcriptome-wide association study (TWAS) was performed to integrate SA GWAS summary statistics from 410,385 individuals (43,901 cases and 366,484 controls) and gene expression data from 49 distinct tissues and obtained from 838 post-mortem donors.

Achondroplasia is the most common disproportionate short-stature skeletal dysplasia. Features associated with achondroplasia are rhizomelia, macrocephaly, midface hypoplasia, and typical cognition. Potential medical complications include foramen magnum stenosis, hydrocephalus, middle ear dysfunction, obstructive and central sleep apnea, spinal stenosis and genu varum.

Purpose: In heart failure (HF) and chronic obstructive pulmonary disease (COPD) populations, sleep-disordered breathing (SDB) is associated with impaired health outcomes. We evaluated whether in patients with HF, concomitant HF and COPD or COPD, the number of hospitalizations would be reduced in the year after testing for SDB with and without treatment initiation compared to the year before.

Methods: We performed a multicentre retrospective study of 390 consecutive sleep-clinic patients who had a primary diagnosis of chronic HF, HF and COPD or COPD and a secondary diagnosis of SDB.

In 2024, several important innovations have enriched the management of respiratory diseases, including pulmonary hypertension, tuberculosis, COPD, and obstructive sleep apnea syndrome (OSAS). Notable advancements include the introduction of sotatercept in Switzerland for pulmonary arterial hypertension and mediastinal cryobiopsies, reflecting a shift toward more personalized medicine. Meanwhile, biologic therapies for COPD offer promising perspectives, and a potential path is emerging for shortening the treatment of certain forms of tuberculosis.
