The risk of bone fracture is high in patients with chronic kidney disease (CKD), and aggressive treatment to reduce fragility fracture risk is the major strategy. However, the outcomes of osteoporosis medications in patients with CKD remain unclear. ⋯ 67 650 patients were included. After propensity score matching, 1654 patients were included in the study and control group, respectively. The mean age was 70.2±12.4 years, and 32.0% of patients were men. After a mean follow-up of 3.9 years, the incidence rates of bone fracture, CV events and all-cause mortality were 2.0, 1.7 and 6.5 per 1000 person-months, respectively. Multivariate analysis results showed that osteoporosis medications reduced the risk of CV events (HR, 0.35; 95% CI, 0.18 to 0.71; p = 0.004), but did not alleviate the risks of bone fracture (HR, 1.48; 95% CI, 0.73 to 2.98; p = 0.28) and all-cause mortality (HR, 0.93; 95% CI, 0.67 to 1.28; p = 0.65). Stratified analysis showed that bisphosphonates users have most benefits in the reduction of CV events (HR, 0.26; 95% CI, 0.11 to 0.64; p = 0.003). In conclusion, osteoporosis medications did not reduce the risk of bone fractures, or mortality, but improved CV outcomes in patients with CKD.

As functional changes precede structural changes in dementia, we aimed to elucidate changes on cerebral perfusion CT (PCT) for early diagnosis of dementia; and to differentiate Alzheimer's disease (AD) from vascular dementia (VaD). We also aimed to study correlation between Montreal Cognitive Assessment (MOCA) score and PCT parameters. ⋯ PCT is a reliable imaging modality for early diagnosis of dementia and in differentiating VaD from AD. As perfusion parameters show positive correlation with MOCA score, they could be used as a surrogate marker of cognitive status in the follow-up of patients with dementia.

To evaluate the prevalence and incidence of significant structural heart disease in targeted patients with cardiac symptoms referred by general practitioners (GPs) using open access echocardiography, without prior clinical evaluation by a cardiologist. ⋯ Major structural and functional cardiac abnormalities are common in late middle-aged patients who present to GPs with cardiac symptoms and signs. Reported, unrestricted open access echocardiography enables early detection of significant cardiac pathology and timely intervention may improve cardiovascular outcomes.

Involvement in research plays an integral role in the delivery of high-quality patient care, benefitting doctors, patients and employers. It is important that access to clinical academic training opportunities are inclusive and equitable. To better understand the academic trainee population, distribution of academic posts and their reported experience of clinical training, we analysed 53 477 anonymous responses from General Medical Council databases and the 2019 National Training Survey. ⋯ At more senior levels, academic trainees are significantly more likely to be of white ethnicity, although among UK graduates, no ethnicity differences were seen. Foundation academic trainees report a poorer experience of some aspects of their clinical training placements, with high workloads reported by all academic trainees. Our work highlights important disparities in the demographics of the UK clinical academic trainee population and raises concerns that certain groups of doctors face barriers accessing and progressing in UK academic training pathways.

The WHO classification of lung cancer (2015) is based on immunohistochemistry and molecular evaluation. This also includes microscopic analysis of morphological patterns that aids in the pathological diagnosis and classification of lung cancers. Lung cancers are the leading cause of cancer deaths worldwide. ⋯ This article reviews the genetic profile of adenocarcinoma, squamous cell carcinoma, small cell carcinoma, large cell neuroendocrine carcinoma and pulmonary carcinoids. This includes the prolific genetic alterations and novel molecular changes seen in these tumours. In addition, target- specific drugs that have shown promising effects in clinical use and trials are also briefly discussed.
