It is unclear whether metabolic and inflammatory factors mediate the association between severe sleep apnea and coronary heart disease (CHD) in observational studies based on the large-scale population. This study aims to assess the association between severe sleep apnea and CHD and to explore the extent to which this association is mediated by metabolic factors and C-reactive protein (CRP). ⋯ Severe sleep apnea was associated with an increased risk of CHD. Lipid factors might play an essential role in the severe sleep apnea-CHD relationship. CRP increased the magnitude of mediation effects of overall metabolic factors. What is already known on this topic It is unknown whether the association between severe sleep apnea and CHD among the large population-based cohort study. Evidence on the mediating effect of metabolic and inflammatory factors in the severe sleep apnea-CHD association remains unclear. What this study adds Lipid factors were the biggest mediation driver in the severe sleep apnea-CHD path. C-reactive protein increased the magnitude of mediation effects of overall metabolic factors. How this study might affect research, practice or policy Investigating mediation analyses not only enhances comprehension of the pathophysiological connection between severe sleep apnea and CHD but also offers valuable insights into preventing CHD.

We aimed to examine the cost-related prescribing performance of primary care physicians who had a higher versus lower tendency of arbitrary prescribing. ⋯ Our study showed that physicians who had a higher tendency of prescribing for no clear indication are also more likely to produce costly prescriptions.

Changes in spectrum of biopsy-proven kidney diseases within decade: an analysis based on 10 199 cases from South China.
To assess the regional epidemiological trends of kidney diseases over time in the South China using renal biopsy-proven cases. ⋯ Our study may provide insights for kidney disease prevention and public health strategies. What is already known on this topic The pathological spectrum of kidney diseases has undergone significant transformations in the past decade, driven by the escalating incidence of chronic diseases. Although there are studies exploring the renal biopsy findings from various regions in China which present both similarities and differences in epidemiology, few large-scale reports from the South China in recent decades were published. What this study adds Our findings reveal the following key observations: (i) increased proportion of middle-aged patients leading to the increasing average age at the time of biopsy；(ii) the frequencies of IgA nephropathy and membranous nephropathy (MN) increased significantly, whereas the frequencies of minimal change disease and focal segmental glomerulosclerosis decreased (P < .001) between 2017 and 2021 than in the years 2012 and 2016; (iii) earlier onset of MN in the age group of 45-59 years old was found in our study; and (iv) a higher frequency of hypertension nephropathy and DN presented over time, and frequency of amyloidosis increased in elderly patients diagnosed with NS. How this study might affect research, practice, or policy This single-center yet a large-scale study of the kidney disease spectrum in South China may provide a reference point for the diagnosis, treatment, and prevention of chronic kidney disease.

Myosteatosis indicates pathological fat infiltration in muscles and is regarded as a distinct disease from sarcopenia. This muscular condition exhibits a link to muscle fiber disarrangement coinciding with disrupted muscle contractility and weakened mechanical action, mirrored as decreased muscle quality. However, the relationship between handgrip strength (HGS) and computed tomography-defined myosteatosis among cirrhosis is unclear. We aimed to investigate the association between HGS and myosteatosis and determine gender-specific cutoffs regarding HGS to identify myosteatotic subjects. ⋯ HGS was in close relation to myosteatosis among inpatients with cirrhosis.

During a global pandemic where anaesthetists play a pertinent role in treating coronavirus 2019 (COVID-19), it is crucial to inspire medical students to consider a career in anaesthetics and perioperative care. Where anaesthetic skills are vital for all surgical foundation doctors, regardless of whether they have a rotation in anaesthetics, this study seeks to establish the current level of exposure to anaesthetics in the UK medical schools' curriculum and evaluate if the current anaesthetic undergraduate curriculum is sufficient to prepare students to pass their exams and perform the duties expected of them as future junior doctors. ⋯ Our results demonstrate that there is a lack of standardization in undergraduate anaesthetics teaching nationally and an additional undergraduate anaesthetic teaching programme is required to increase understanding and provide further insight into anaesthetics. Key messages: The emergence of the coronavirus 2019 (COVID-19) pandemic has halted undergraduate medical education, in particular perioperative medicine and surgery.Exposure to anaesthesia is already limited in the medical undergraduate curriculum, with a limited number of anaesthesia-themed foundation rotations available for junior doctors.Recent UK graduates feel that undergraduate anaesthetics education is inadequate at medical school, reporting a lack of confidence in applying undergraduate anaesthesia learning outcomes.Additional anaesthetic teaching and online teaching methods are suggested ways of improving the delivery of undergraduate anaesthetic education.Can a national, standardized anaesthetics teaching curriculum improve the undergraduate knowledge base of anaesthesia?
