Comparative Study
Off-pump versus on-pump coronary artery bypass grafting in elderly patients at 30 days: a propensity score matching study.
Elderly patients are at increased risk of perioperative morbidity and mortality after conventional on-pump coronary artery bypass grafting (ONCABG). This study was to determine whether such high-risk population would benefit from off-pump coronary artery bypass grafting (OPCABG). ⋯ OPCABG is an alternative revascularization method for elderly patients. It reduces the risk of early postoperative renal insufficiency and reoperation for bleeding.

The UK's National Health Service (NHS) faces escalating competition ratios for specialty training positions, with application rates dramatically outpacing the growth in available posts. This trend contributes to systemic bottlenecks and challenges traditional career progression pathways within medicine. In this evolving landscape, the once-certain career progression within medicine is now increasingly uncertain. ⋯ It critically evaluates the implications of current funding policies, which seem to prioritise an expansion of nondoctor healthcare roles over the development of specialist training, raising concerns about the long-term patient care quality and safety. Key recommendations include a reassessment of medical education expansion, a review of funding allocation, increased support for specialty training, and government accountability for healthcare workforce planning. The urgent need for strategic policy reform is underscored to ensure that NHS can sustain a high-quality, specialist-led healthcare provision in the face of rising competition and workforce pressures.

In recent years, immunotherapy strategies based on immune checkpoint inhibitors have yielded good efficacy in colorectal cancer (CRC)especially in colorectal cancer with microsatellite instability-high. However, microsatellite-stable (MSS) CRCs account for about 85% of CRCs and are resistant to immunotherapy. ⋯ Therefore, improving the sensitivity of immunotherapy to MSS CRC is a hot topic which is crucial for the treatment of MSS CRC. This review aims to discuss the factors contributing to MSS CRC insensitivity to immunotherapy and explored potential solutions to overcome immunotherapy resistance.

Randomized Controlled Trial
Multiple intra-articular injections of autologous stromal vascular fractions for the treatment of multicompartmental osteoarthritis in both the tibiofemoral and patellofemoral joint: a single-blind randomized controlled study.
Multicompartmental osteoarthritis (MOA) in both tibiofemoral and patellofemoral joints is a more commonly occurring, but neglected, clinical condition, and we examined the short-term safety and efficacy of autologous stromal vascular fractions (SVFs) for MOA using a single-blind, prospective, randomized, placebo-controlled trial. ⋯ Multiple intra-articular injection of autologous SVF reduces pain and improves function in the short term in patients with early or midstage MOA. However, there was heterogeneity in the improvement of overall knee and isolated patellofemoral joint after treatment.

'Low-value' clinical care and medical services are 'questionable' activities, being more likely to cause harm than good or with disproportionately low benefit relative to cost. This study examined the predictive ability of the QUestionable In Training Clinical Activities Index (QUIT-CAI) for general practice (GP) registrars' (trainees') performance in Australian GP Fellowship examinations (licensure/certification examinations for independent GP). ⋯ Performing questionable clinical activities predicted poorer performance in the summative Fellowship examinations, thereby validating these examinations as measures of actual clinical performance (by our measure of clinical performance, which is relevant for a licensure/certification examination).
