Study Objectives: (1) To determine the prevalence of snoring, breathing pauses during sleep and obstructive sleep apnoea syndrome in the United Kingdom (UK) and determine the relation between these events and obesity and other sociodemographic variables. (2) To compare and integrate this data with published UK population data.
Methods: A total of 664 women and 575 men aged 18-100 years who formed a representative sample of the non-institutionalised UK population participated in an online interview survey directed by a previously validated computerised system.
Results: Overall, 38% of men and 30.4% of women report that they snore at night. Furthermore, 8.7% of men and 5.6% of women state that they stop breathing at night. Comparing our data to published data from the 1990s, this study observes a highly significant increase in the rates of reported breathing pauses during sleep (sleep apnoea) in the UK over the last 20 years (p < 0.0001). In addition, we observe a highly significant increase in the prevalence of obesity (BMI>30) in the UK population between 1994 and 2015 (p < 0.0001). Integration of our data with NHS and public health England data on obesity confirms this increase.
Conclusions: Our data demonstrate a significant increase in the rates of reported breathing pauses during sleep (sleep apnoea) and obesity in the UK over the last 20 years. Sociodemographic and behavioural changes have likely contributed to this. Moreover, our data also suggests that sleep disordered breathing (SDB) is widely underdiagnosed in the UK.

Severe bradycardia in patients with obstructive sleep apnoea and good early response to CPAP.
Sleep Breath
January 2025
Department of Cardiac and Vascular Diseases, Jagiellonian University Medical College, John Paul II Hospital, Prądnicka 80, Kraków, 31-202, Poland.
Background: Obstructive sleep apnoea (OSA) may lead to heart rhythm abnormalities including bradycardia. Our aim was to ascertain clinical and echocardiographic parameters in patients with OSA in whom severe bradycardia was detected in an outpatient setting, as well as to evaluate the efficacy of CPAP therapy on heart rate normalization at the early stages of treatment.
Methods: Fifteen patients mild, moderate or severe OSA and concomitant bradycardia were enrolled.
Assessing the Clinical and Functional Status of COPD Patients Using Speech Analysis During and After Exacerbation.
Int J Chron Obstruct Pulmon Dis

Department of Cardiology, Respiratory Medicine and Intensive Care, University Hospital Augsburg, Augsburg, Germany.
Background: Chronic obstructive pulmonary disease (COPD) affects breathing, speech production, and coughing. We evaluated a machine learning analysis of speech for classifying the disease severity of COPD.
Methods: In this single centre study, non-consecutive COPD patients were prospectively recruited for comparing their speech characteristics during and after an acute COPD exacerbation.
Nitrosyl factors play a vital role in the ventilatory depressant effects of fentanyl in freely moving guinea pigs.
Biomed Pharmacother

Department of Pediatrics, Case Western Reserve University, Cleveland, OH, USA; Department of Pharmacology, Case Western Reserve University, Cleveland, OH 44106, USA.
An understanding of intracellular mechanisms by which fentanyl and other synthetic opioids exert adverse effects on breathing is needed. Using freely moving adult male guinea pigs, we administered the nitric oxide synthase (NOS) inhibitor, L-NAME (N-nitro-L-arginine methyl ester), to determine whether nitrosyl factors, such as nitric oxide and S-nitrosothiols, play a role in fentanyl-induced respiratory depression. Ventilatory parameters were recorded by whole body plethysmography to determine the effects of fentanyl (75 μg/kg, IV) in guinea pigs that had received a prior injection of vehicle (saline), L-NAME or the inactive D-isomer, D-NAME (both at 50 μmol/kg, IV), 15 min beforehand.

The concentrations of nasal nitric oxide (nNO) vary in patients with chronic rhinosinusitis (CRS) supposedly depending upon whether the paranasal ostia are open or obstructed. Our aim was to assess whether nNO levels and their response to topical xylometazoline (a local vasoconstrictor used to alleviate nasal congestion) in patients with CRS differ between those with open or obstructed ostia and if the results were altered by the use of nasal corticosteroids. Sixty-six patients with CRS (43% with nasal polyps) or recurrent acute rhinosinusitis and 23 healthy controls were included.

JAMA Pediatr
January 2025
Department of Pediatrics, Duke University School of Medicine, Durham, North Carolina.
Importance: Preterm infants are recommended to receive most vaccinations at the same postnatal age as term infants. Studies have inconsistently observed an increased risk for postvaccination apnea in preterm infants.
Objective: To compare the proportions of hospitalized preterm infants with apnea and other adverse events in the 48 hours after 2-month vaccinations vs after no vaccinations.
