Poststenotic dilatation in renal artery stenosis, evaluated at abdominal CT, might be related to stenotic kidney damage and inflammation, particularly to monocyte chemoattractant protein-1 release.

Abstract Pain treatments have modest effects. Health outcomes might be improved if treatments are matched to mechanisms underlying the persistence and biopsychosocial impact of an individual's pain. The International Association for the Study of Pain (IASP) defines 3 mechanistic pain descriptors presumed to involve different mechanisms—nociceptive, neuropathic, and nociplastic. Although treatments to address each descriptor have been proposed, there is no consensus on how to assign descriptors to clinical presentations. A recent consensus identified candidate clinical features to discriminate between descriptors in clinical practice and research. These need refinement to progress towards a tool. This study aimed to determine the rank and relative weight of identified clinical features to aid discrimination between mechanistic pain descriptors. Candidate clinical features (n = 196) were refined by the IASP Terminology Task Force to converge similar and remove redundant features. The Task Force (n = 24) and an expert panel (n = 39) ranked features using 1000minds conjoint analysis software and assigned weights based on discrete pairwise choices. Participants nominated from pairs of scenarios, which most likely indicated that pain aligned predominantly to a descriptor. Highest ranked features for neuropathic and nociplastic pain were aligned with IASP Clinical Criteria. Criteria for nociceptive pain have not been established. A ranked list of features shared by 2 mechanisms (indicating mixed mechanisms) was also identified. This study identified expert consensus on the highest ranked clinical features with potential to discriminate between pain descriptors, reflective of different underlying mechanisms. This study extends current frameworks by identifying and refining key discriminators for future operationalisation and validation.

Measles virus (MeV) infection is mediated by two cellular receptors: signaling lymphocytic activation molecule family member 1 (SLAMF1, also known as CD150), expressed by immune cells, and nectin-4, expressed by epithelial cells. Infection of immune cells causes systemic disease and immune suppression, while infection of airway epithelial cells results in efficient transmission. In rare cases, MeV reaches the brain and slowly spreads in cells that do not express bona fide receptors, causing subacute sclerosing panencephalitis (SSPE). In the brains of persons with SSPE, multiple mutations of the MeV membrane fusion apparatus are selected that enable its triggering by host proteins acting as surrogate receptors. These mutations favor cell-to-cell spread, which promotes population-based MeV genome evolution and the formation of collective infectious units (CIUs). CIUs, which can rebalance their components and rapidly adapt to new environments, may support neuropathogenesis of other nonintegrating RNA viruses, in particular those with nonsegmented negative-strand genomes.

Abstract Purpose: Familial adenomatous polyposis (FAP) confers a significant risk of colorectal/duodenal cancer. Encapsulated rapamycin (eRapa) has demonstrated promise as FAP chemoprevention in early clinical studies. Patients and Methods: Thirty patients with FAP enrolled to three dosing regimens of eRapa (0.5 mg): cohort 1—every other day, cohort 2—daily every other week, or cohort 3—daily. The primary endpoints were safety/tolerability, pharmacokinetics, and percentage change from baseline (PCFB) in colorectal polyp burden (CPB) at 6 months. Secondary endpoints included PCFB total (TPB) and duodenal (DPB) polyp burden and change in International Society for Gastrointestinal Hereditary Tumors stage and Spigelman score at 6 and 12 months. Results: Twenty nine of thirty patients (97%) completed the 12-month study with predictable bioavailability. Low-grade adverse events were frequent but most pronounced in daily dosing. Two patients discontinued treatment related to toxicity. Cohort 1 had the largest decrease median PCFB CPB, DPB, and TPB at 6 months: −39.4 % (IQR, 108.9; P = 0.28), −33.33 % (IQR, 90; P = 0.04), and −38.6 % (IQR, 88.5; P = 0.26), respectively. At 12 months, cohort 2 had the largest decrease median PCFB CPB and TPB: −29.3 % (IQR, 67.6; P = 0.37) and −26.3 % (IQR, 49.5; P = 0.29), respectively. Intermittent dosing cohorts (1 and 2) reduced DPB at 6 months (P = 0.04) and improved TPB at 12 months (P = 0.05) compared with daily dosing. Conclusions: eRapa was safe, tolerable, and showed preliminary efficacy for FAP chemoprevention. The 0.5 mg daily every-other-week schedule will be evaluated in an upcoming phase III trial.

Patients with inflammatory bowel disease (IBD) frequently modify their diet and use complementary medicine, but inconsistent evidence and persistent myths complicate clinical guidance. Our aim was to critically evaluate the evidence for dietary and complementary strategies in IBD and to clarify common misconceptions, supporting evidence-based, patient-centred management. A narrative synthesis of randomised trials, systematic reviews and international guidelines was conducted. Interventions that were evaluated included dietary strategies encompassing the Mediterranean diet, low-FODMAP (Fermentable Oligosaccharides, Disaccharides, Monosaccharides and Polyols) diet, exclusive enteral nutrition, Crohn’s disease exclusion diet and the specific carbohydrate diet. Other interventions included complementary modalities such as probiotics, curcumin, herbal medicine, mind-body interventions and physical activity. The Mediterranean diet shows moderate evidence for improving quality of life and inflammatory biomarkers. A low-FODMAP diet can relieve functional symptoms but does not reduce inflammation. Exclusive enteral nutrition remains first-line induction therapy in paediatric Crohn’s disease. The Crohn’s disease exclusion diet/partial enteral nutrition shows promise in adults. Among complementary therapies, specific probiotics and curcumin demonstrate benefits in certain cases of ulcerative colitis, but evidence for their use in Crohn’s disease remains limited. Personalised, multidisciplinary supervised dietary and complementary approaches may support symptom control and quality of life in IBD patients. However, they should complement rather than replace evidence-based pharmacologic therapy, and high-quality trial and clinical studies are needed to define optimal, evidence-based nutritional strategies.

Multi-listing (ML) increases the odds of transplantation compared with single-center listing. However, not all patients have equivalent access to ML. The recent allocation policy change prioritized distance from the donor hospital in an attempt to decrease geographic disparities. This study assessed access to liver transplant (LT) given ML practices before and after the acuity circles policy change. United Network for Organ Sharing data were queried for LTs between January 1, 2016, and November 1, 2024. Patients were grouped by listing at one versus multiple centers and by acuity circle era (ACE). Cohort characteristics and comparisons were described using chi-square and Wilcoxon rank tests. Multivariable logistic regressions and propensity score match (PSM) were performed to assess associations between ML and LT. The final cohort consisted of 105,030 patients; 4084 (3.9%) were multi-listed. Racial/ethnic minority groups, less educated, and publicly insured candidates were less often multi-listed. ML was positively associated with LT in all analyses (overall: OR=1.180, p <0.001; PSM: OR=1.164, p =0.001; pre-ACE: OR=1.127, p =0.015; post-ACE: OR=1.218, p <0.001). Education, race/ethnicity, and insurance type were also associated with LT across all analyses. ML patients were more often transplanted at their primary center with a significant increase in primary center LT post-ACE (53.4% vs. 63.4%, p <0.001). ML and LT had a positive correlation. There was a negative association between minority groups and ML as well as LT. Although acuity circles decreased geographic disparities, they did not change ML accessibility across candidates.

Abstract The International League Against Epilepsy (ILAE) is a global organization dedicated to improving the lives of people with epilepsy through education, research, and advocacy. Recognizing the need for broader engagement and multidisciplinary collaboration, the ILAE has established five sections: Young Epilepsy Section (YES), Nursing, Social Work and Social Services (SWSSS), Neurotechnology, and Pharmacy. These sections aim to strengthen professional networks, enhance education, and promote innovation in epilepsy care. YES fosters leadership and participation among early‐career professionals, whereas the Nursing Section addresses gaps in epilepsy‐specific training and competency development. SWSSS emphasizes psychosocial care, advocacy, and health equity, supporting Intersectoral Global Action Plan (IGAP) objectives through culturally sensitive interventions. The Neurotechnology section advances the integration and development of innovative tools for diagnosis and treatment, and the Pharmacy section focuses on optimizing medication management and access to antiseizure medications globally. Collectively, these sections contribute to the WHO IGAP by improving policy, care delivery, research, and public health responses. Looking ahead, ILAE seeks to expand multidisciplinary participation, encourage cross‐sectional collaboration, and maintain its role as a leading force in global epilepsy care. Through these initiatives, ILAE continues to build capacity, foster inclusivity, and drive progress toward equitable, comprehensive epilepsy services worldwide. Plain Language Summary The International League Against Epilepsy (ILAE) is the global organization responsible for all healthcare professionals involved in the care of those with epilepsy. Recognizing the increasing number of different disciplines now contributing to epilepsy care, and the need to develop professionals of the future, the ILAE has recognized “sections” of like‐minded individuals to encourage networking and communication. Together, these sections contribute to the WHO Intersectoral Global Action Plan (IGAP) by improving policy, care delivery, research, and public health responses. Moving forward, the ILAE seeks to expand multidisciplinary participation, encourage collaboration, and maintain its role as a leading force in global epilepsy care.
