Background And Objectives: Social media platforms such as X (formerly Twitter) are increasingly used in medical education. Characteristics of tweetorials (threaded teaching posts) associated with higher degrees of engagement are unknown. We sought to understand features of neurology-themed tweetorials associated with high sharing and engagement.

Introduction: Congenital colour vision deficiency (CVD), known as colour blindness, is a common visual problem affecting around 1 in 12 men and 1 in 200 women. It is known that people who have red-green CVD, the most common phenotype, can have difficulty differentiating colours and this can impact the ability to perform clinical tasks related to patient care. The objective of this scoping review is to understand the extent and type of evidence and the impact on clinical practice and patient safety arising from congenital CVD in healthcare professionals.

Increasing evidence supports the presence of oxytocin deficiency (OXT-D) in patients with hypopituitarism and hypothalamic damage (HHD), that might be associated with neuropsychological deficits and sexual dysfunction, leading to worse quality of life (QoL). Therefore, identifying a provocative test to diagnose an OXT-D will be important. Corticotropin-releasing hormone (CRH) is a candidate for such a test as it increases oxytocin secretion in animal models.

Background: Individuals with avoidant/restrictive food intake disorder (ARFID) self-report heightened sensitivity to taste and smell, but neither phenomenon has been systematically explored in the laboratory. We hypothesized that, compared to healthy controls (HC, n = 34), children, adolescents, and adults with full/subthreshold ARFID (n = 100; ages 9 to 23 years) would self-report heightened response to taste/smell stimuli and exhibit stronger bitter taste perception and heightened smell perception in performance-based tasks, and these differences would be especially prominent in those with the ARFID-sensory sensitivity presentation.

Method: We measured self-reported sensitivity to taste/smell with the adolescent/adult sensory profile (AASP).

We present a case of a woman in her 40s with disseminated enterovirus infection in the setting of maintenance therapy with ocrelizumab for relapsing-remitting multiple sclerosis. The patient originally presented with fever, bilateral lower limb swelling and hypoalbuminaemia. She subsequently developed a productive cough and diarrhoea, and a viral respiratory multiplex panel detected rhino/enterovirus.

Background: Appetite-regulating hormones are implicated in anorexia nervosa (AN) pathophysiology, however, data are limited for appetite-regulating hormones across the AN weight spectrum. We aimed to investigate fasting and post-prandial concentrations of appetite-regulating hormones - peptide YY (PYY), cholecystokinin (CCK), and ghrelin - among adolescent and young adult females across the AN weight spectrum, specifically those with AN and Atypical AN, and healthy controls (HC).

Methods: Participants (N = 95; ages 11-22 years) included 33 with AN, 25 with Atypical AN, and 37 HC.

Objective: Mechanisms underlying metabolic improvement following metabolic and bariatric surgery (MBS) may provide insight into novel therapies. Vasopressin improves body composition and protects against hypoglycemia. Associations of copeptin, a stable cleavage product of vasopressin, with BMI and insulin resistance suggest an adaptive increase in vasopressin to counteract metabolic disruption.

Liberia, in the face of two consecutive health emergencies - the Ebola epidemic in 2014 and COVID in 2019 - offers a unique, comparative perspective on health crisis management within a fractured healthcare system. In dialogue with a feminist-informed political economy of health in the African context, this paper has two central objectives. First, it examines the strategies employed by community-based women's organisations - many of whom remain invested in peacebuilding after a 14-year civil war (1989-2003)) - to contain the Ebola and COVID-19 disease outbreaks.

Objective: Cognitive-behavioral therapy for avoidant/restrictive food intake disorder (ARFID; CBT-AR) shows promise in improving clinical outcomes in children/adolescents and adults. We aimed to identify predictors of outcomes in CBT-AR. We hypothesized that younger age, non-underweight status, and presence of the fear of aversive consequences profile of ARFID would predict greater likelihood of remission post-treatment, and that presence of the lack of interest in eating/food and sensory sensitivity profiles would predict greater likelihood of persistence post-treatment.

Introduction: Patients with rectal cancer face a potentially life-limiting disease with multi-modal treatment options conferring substantial symptom burdens. Treatment decisions frequently require trade-offs and input from a multidisciplinary team: ideal cases for shared decision-making. Using qualitative analysis, we characterized the content of communication between surgeons and patients who have rectal cancer.

Background: Patients in rural areas have reduced colonoscopy access, which is critical for colorectal cancer prevention. General surgeons perform most colonoscopies in rural areas. The Surgical Collaborative of Wisconsin's Rural Task Force identified colonoscopy as a high priority initiative due to high volume and lack of quality measure access, both necessary for assessing and improving performance.

Article Synopsis
  • Policymakers employed non-pharmaceutical interventions (NPIs) to curb COVID-19 transmission before vaccines were available, but research on their effectiveness remains limited and inconsistent across various studies.
  • This study analyzed 61 articles from China, Italy, the UK, and the US to evaluate the impact of NPIs on reducing disease transmission, finding substantial variation in their effectiveness estimates.
  • NPIs can reduce transmission by 40 to 90%, with stricter interventions like lockdowns showing greater effectiveness, but a lack of standard definitions and categories hinders comparability among studies.

The lipidomic secretions of embryos provide a unique opportunity to examine the cellular processes of the early conceptus. In this study we profiled lipids released by the early equine conceptus, using high-resolution mass spectrometry to detect individual lipid species. This study examined the lipidomic profile in embryo-conditioned media from -produced, 8-9 day-old equine embryos ( = 3) cultured for 36 h, analyzed over 3 timepoints.

Objective: Uptake of evidence-informed health care transition processes among pediatric rheumatologists is low despite poor outcomes of transition from pediatric to adult care. We piloted a learning collaborative model to implement transition guides. We dually assessed implementation outcomes and changes in reported patient-care team discussions about transition.

Introduction: Successful organ transplantation in patients with end-stage organ failure improves long-term survival, improves quality of life and reduces costs to the NHS. Despite an increase in the number of deceased organ donors over the last decade, there remains a considerable shortfall of suitable organs available for transplantation. Over half of UK donors are certified dead by neurological criteria following brain stem compression, which leads to severe physiological stress in the donor, combined with a hyperinflammatory state.

Carcinomas are associated with metastasis to specific organs while sparing others. Breast cancer presents with lung metastasis but rarely kidney metastasis. Using this difference as an example, we queried the mechanism(s) behind the proclivity for organ-specific metastasis.

Article Synopsis
  • Squamous cell carcinoma of the anus (SCCA) is becoming more common in the U.S., and while standard treatments have high toxicity, carboplatin and paclitaxel (C/P) combined with radiation may offer a safer alternative for patients who can't tolerate standard chemoradiation.
  • In a study with ten patients (average age 75.5), 89% achieved a complete clinical response, and 67% remained alive without recurrence after a median follow-up of about 26 months.
  • Common toxicities included leukopenia, anemia, and diarrhea, with severe side effects affecting a notable percentage, but overall, the C/P regimen showed good tolerability and effectiveness.

Background: Major depressive disorder (MDD) is common worldwide and can be highly disabling. People with MDD face many barriers to treatment and may not experience full symptom relief even when treated. Therefore, new treatment modalities are needed for MDD.
