Temperature control is a fundamental intervention for neuroprotection following resuscitation from cardiac arrest. However, evidence regarding the efficacy of hypothermia in post-cardiac arrest syndrome (PCAS) remains unclear. Retrospective studies suggest that the clinical effectiveness of hypothermia may depend on the severity of PCAS. The R-CAST OHCA trial aims to compare the efficacy of hypothermia versus normothermia in improving 30-day neurological outcomes in patients with moderately severe PCAS following out-of-hospital cardiac arrest.
The multicentre, single-blind, parallel-group, superiority, randomised controlled trial (RCT) is conducted with the participation of 35 emergency and critical care centres and/or intensive care units at academic and non-academic hospitals. The study enrols moderately severe PCAS patients, defined as those with a revised post-Cardiac Arrest Syndrome for induced Therapeutic Hypothermia score of 5.5–15.5. A target number of 380 participants will be enrolled. Participants are randomised to undergo either hypothermia or normothermia within 3 hours after return of spontaneous circulation. Patients in the hypothermia group are cooled and maintained at 34°C until 28 hours post-randomisation, followed by rewarming to 37°C at a rate of 0.25°C/hour. Patients in the normothermia group are maintained at normothermia (36.5°C–37.7°C). Total periods of intervention, including the cooling, maintenance and rewarming phases, will occur 40 hours after randomisation. Other treatments for PCAS can be determined by the treating physicians. The primary outcome is a favourable neurological outcome, defined as Cerebral Performance Category 1 or 2 at 30 days after randomisation and compared using an intention-to-treat analysis.

BackgroundColorectal cancer (CCR) is one of the leading causes of death worldwide. Early detection remains a highly effective strategy for curing this disease. In France, despite a free organised screening programme for people aged between 50 and 74, participation rates remain suboptimal. Socioeconomic position and health literacy levels exacerbate the situation, with the lowest screening rates observed in the most socially disadvantaged areas. This study assessed patients’ and General Practitioners’ (GP) views on the acceptability of an intervention to increase screening uptake using a simple brochure and video on the importance and process of CCR screening.
MethodWe conducted a cross-sectional qualitative study using semi-structured interviews with patients (n = 24) and GPs (n = 22) who used or participated in the DECODE project intervention. The interviews were conducted by telephone or videoconference and analysed thematically using Nvivo software and dual independent coding.
Results95% of GPs expressed a clear preference for the video over the brochure. Patients had varied results with 50% preferring the video, as it demonstrated how to do the test, versus the brochure. The humorous and de-dramatising aspects of the video were the two key factors highlighted by interviewees. However, support from healthcare staff (GPs, nurses, etc.) is still essential, in supporting patients in prevention. This presents a challenge for GPs, who are frequently constrained by time limitations during consultations.
ConclusionOur findings emphasize the need to tailor promotional materials for both patients and healthcare professionals to improve CCR screening uptake, balancing digital efficiency with maintaining core human relationships in healthcare. Such intervention can be integrated into different workflows. The addition of video into national CRC screening programs might also help. Targeting CRC screening interventions at provider-patient interactions, ensuring they are tailored, accessible, and engaging, is key to reducing disparities.

To evaluate the incidence and risk factors for psychiatric disorders, including depression and anxiety, and assess the risk of suicide in patients with polymyositis (PM) and dermatomyositis (DM).
Retrospective cohort study.
Data were obtained from Taiwan’s National Health Insurance Research Database (NHIRD) between 2000 and 2018.
A total of 3477 patients with PM/DM and 13 908 age- and sex-matched non-PM/DM controls were included in the study.
The primary outcome was the incidence and risk of psychiatric disorders in patients with PM/DM compared with controls. Secondary outcomes included the identification of risk factors for psychiatric disorders, mortality and suicide risk in the PM/DM cohort.
The incidence rate ratio (IRR) of psychiatric disorders was significantly higher in the PM/DM cohort than in controls (IRR 1.62, 95% CI 1.39 to 1.89), with depression being the most prevalent disorder (IRR 2.25, 95% CI 1.83 to 2.75). Key risk factors included female sex, intravenous steroid therapy, and high-dose oral steroid use. Additionally, the PM/DM cohort exhibited a higher mortality rate (IRR 3.4, 95% CI 3.15 to 3.67) and elevated suicide risk (IRR 1.99, 95% CI 0.96 to 3.86) compared with controls.
Patients with PM/DM face a significantly higher risk of psychiatric disorders, mortality and suicide. Integrating mental healthcare into the routine management of PM/DM is crucial to improving patient outcomes and reducing mortality. Future research should focus on the impact of early psychiatric interventions on survival outcomes in this population.

A general-purpose method of emphasizing abnormal lesions in chest radiographs, named EGGPALE (Extrapolative, Generative and General-Purpose Abnormal Lesion Emphasizer), is presented. The proposed EGGPALE method is composed of a flow-based generative model and L-infinity-distance-based extrapolation in a latent space. The flow-based model is trained using only normal chest radiographs, and an invertible mapping function from the image space to the latent space is determined. In the latent space, a given unseen image is extrapolated so that the image point moves away from the normal chest X-ray hyperplane. Finally, the moved point is mapped back to the image space and the corresponding emphasized image is created. The proposed method was evaluated by an image interpretation experiment with nine radiologists and 1,000 chest radiographs, of which positive suspected lung cancer cases and negative cases were validated by computed tomography examinations. The sensitivity of EGGPALE-processed images showed +0.0559 average improvement compared with that of the original images, with -0.0192 deterioration of average specificity. The area under the receiver operating characteristic curve of the ensemble of nine radiologists showed a statistically significant improvement. From these results, the feasibility of EGGPALE for enhancing abnormal lesions was validated. Our code is available at https://github.com/utrad-ical/Eggpale.
An essential intervention for patients with end-stage renal disease is kidney transplantation. Nonetheless, patient outcomes are substantially affected by complications associated with postoperative wounds. The purpose of this research was to determine the prevalence, risk factors and repercussions of wound-related complications among kidney transplant recipients. A cross-sectional observational study was undertaken at Qilu Hospital of Shandong University Department of Organ Transplantation, China. Included in the study were 118 patients who had undergone kidney transplantation during the specified time period. Medical record evaluations, questionnaires and patient interviews were utilized to collect data, with an emphasis on demographics, transplant information, postoperative care and wound complications. Infection, dehiscence, lymphocoele, delayed wound healing, seroma formation and haematoma were classified as complications. The presence of comorbidities, age over 50 and living donor transplants were identified as significant risk factors for postoperative complications. The most prevalent complications observed were delayed wound healing (21.2%) and infections (16.9%) (p < 0.05). Antibiotics were found to be effective in managing infections, while prolonged conservative management was necessary for delayed wound healing. Prominent complications that recurred were infections and wound healing delays. No statistically significant correlation was observed between gender, BMI and prior transplants with the occurrence of complications (p > 0.05). The research highlighted the significance of taking into account patient-specific variables, including age and concurrent medical conditions, when conducting post-kidney transplantation treatment. The results supported the use of individualized strategies in postoperative care, particularly for populations at high risk, in order to reduce the incidence and severity of complications associated with wounds in pursuit to enhancing clinical practices and formulating focused intervention strategies to improve patient outcomes following transplantation.
