Patients with hypercholesterolemia often have coronary microvascular dysfunction (CMD). Viral infections, such as the SARS-CoV-2 infection, may also result in CMD. Three non-randomized studies have shown significant beneficial effects of statins on CMD in non-infected patients. ⋯ Apart from statins, lipoprotein apheresis and PCSK9 inhibitors can also improve or even reverse CMD. The potential reversal of CMD by using effective cholesterol-lowering medications during and after COVID-19 infection, especially in hypercholesterolemic COVID-19 patients, is important. KEY MESSAGESCoronary microvascular dysfunction (CMD) is common in patients hospitalized with SARS-CoV-2 infectionThree nonrandomized studies in non-infected patients are showing the beneficial effects of statin treatment on CMDEffective cholesterol-lowering medication during and after SARS-CoV-2 infection, especially in hypercholesterolemic COVID-19 patients, is of great significance.

Hypokalaemia is a side-effect of diuretics. We aimed to use machine learning to identify features predicting hypokalaemia risk in hypertensive patients. ⋯ Our predictive model based on the random forest algorithm performed best among the tested and evaluated five algorithms. Hypokalaemia-associated key features have been identified in hypertensive patients and the subgroup with CVD. These findings from machine learning facilitate the development of artificial intelligence to highlight hypokalaemia risk in hypertension patients.

The future composition of a country's physician workforce depends on medical students' choices of specialties. Students' familiarity with the job market (the healthcare system) they are about to enter and the influence job market conditions have on their choices has not been well explored. This study focuses on whether and how the healthcare system's employment landscape is taken into consideration by medical students and whether this facet adds information about the specialty selection process. ⋯ This study demonstrated the utility of querying medical students about their market awareness when investigating the specialty selection process. Students' poor rating of selection criteria, such as specialties with ease in finding jobs because they are suffering workforce shortages and have empty positions, provide insights and concerns for healthcare leaders. It should aid them in approaching the challenge of attracting students to specialties with workforce shortfalls.KEY MESSAGESThis study demonstrated the feasibility and potential value of adding queries about market awareness when investigating the medical student specialty selection process.Medical students were more interested in a specialty that provides job security than one where it is easy to find work.It could be useful for the healthcare leadership and medical educators in all countries to learn what medical students know about their national healthcare system and whether they need to add more healthcare delivery and system subjects to their curricula.

Low-grade glioma (LGG), which is the second most frequent adult brain malignancy, severely threatens patients' health and has a high recurrence rate. Histone H3/H4 chaperone anti-silencing function 1 B (ASF1B) has a tight association with the initiation and development of tumours. The expression and regulation mechanism of ASF1B in LGG were discussed. ⋯ The interaction between ASF1B and TLK1 promoted the malignant progression of LGG.Key messagesTLK1 interacts with ASF1B.Interference with ASF1B inhibits the proliferative, invasive and migratory capabilities and induces the cycle arrest, along with the apoptosis of LGG cells.The interaction between ASF1B and TLK1 promotes the malignant progression of LGG.

Osteoporotic individuals suffer from various complications such as spontaneous bone fractures due to decreased bone strength and failure in bone healing as a result of decreased bone mineral density and deterioration of bone microstructure. In this study, the effects of Extracorporeal Shock Wave Therapy (ESWT) in a distraction osteogenesis model in osteoporotic rabbits were investigated to prevent these failures and improve bone microstructure. ⋯ The application of ESWT in these parameters after osteotomy was beneficial for bone regeneration in mandibular distraction in osteoporotics. However, ESWT has been shown to be ineffective in improving bone mineral density.KEY MESSAGESThe osteoporotic model can be successfully established in rabbits and the subjects can tolerate the distraction procedures.Stereology is a useful analysis method that can determine the volume of the new bone formation and neoangiogenesis.Extracorporeal shock wave therapy has biostimulatory effects on bone tissue.
