The present study investigated the neuromodulatory substrates of salience processing and its impact on memory encoding and behaviour, with a specific focus on two distinct types of salience: reward and contextual unexpectedness. 46 Participants performed a novel task paradigm modulating these two aspects independently and allowing for investigating their distinct and interactive effects on memory encoding while undergoing high-resolution fMRI. By using advanced image processing techniques tailored to examine midbrain and brainstem nuclei with high precision, our study additionally aimed to elucidate differential activation patterns in subcortical nuclei in response to reward-associated and contextually unexpected stimuli, including distinct pathways involving in particular dopaminergic modulation.

Background: The inclusion of clinical frailty in the assessment of patients planned for major surgery has proven to be an independent predictor of outcome. Since approximately half of all patients in the UK diagnosed with oesophagogastric (OG) cancer are over 75 years of age, assessment of frailty may be important in selection for surgery.
Materials And Methods: This retrospective cohort study applied the Hospital Frailty Risk Score to data obtained from the NHS Secondary Uses Service electronic database for patients aged 75 years or older undergoing oesophagectomy and gastrectomy between April 2017 and March 2020.

Background: Psilocybin therapy (PT) produces rapid and persistent antidepressant effects in major depressive disorder (MDD). However, the long-term effects of PT have never been compared with gold-standard treatments for MDD such as pharmacotherapy or psychotherapy alone or in combination.
Methods: This is a 6-month follow-up study of a phase 2, double-blind, randomised, controlled trial involving patients with moderate-to-severe MDD.

Emerging research has highlighted the significant role of microbiota-gut-brain communication in child psychiatric disorders, including autism spectrum disorder (ASD) and anxiety disorders. Despite this, mainstream psychiatric interventions for children continue to focus predominantly on neurological and psychological therapies, neglecting the critical influence of gut microbiota on brain development and behavior. This commentary underscores the need for greater integration of microbiota-targeted therapies, such as dietary interventions, prebiotics, and probiotics, into early psychiatric intervention strategies.

Ataxia-telangiectasia (A-T) is an ultrarare autosomal recessive disorder and occurs in all racial and ethnic backgrounds. Clinically, children and young people with A-T are affected by sinopulmonary infections, neurological deterioration with concomitant bulbar dysfunction, increased sensitivity to ionizing radiation, immunodeficiency, a decline in lung function, chronic liver disease, endocrine abnormalities, cutaneous and deep-organ granulomatosis, and early death. Pulmonary complications become more frequent in the second decade of life and are a leading cause of death in individuals with A-T.

Background: There has been limited success of cancer immunotherapies in the treatment of ovarian cancer (OvCa) to date, largely due to the immunosuppressive tumour microenvironment (TME). Tumour-associated macrophages (TAMs) are a major component of both the primary tumour and malignant ascites, promoting tumour growth, angiogenesis, metastasis, chemotherapy resistance and immunosuppression. Differential microRNA (miRNA) profiles have been implicated in the plasticity of TAMs.

Background: Protecting the health of migrants and refugees during the pandemic was a significant challenge in the Latin American region. We aimed to describe and contrast the response of the health systems of Mexico, Colombia and Perú to migrants' and refugees' health needs during the COVID-19 pandemic, and to situate the response in the context of the migration and health policies of each country.
Methods: We conducted case studies of the three countries.

Background: Negative perceptions of mental health professionals can deter individuals from seeking mental healthcare. Given the high burden of mental health globally, it is essential to understand attitudes towards mental health professionals. Social media platforms like Twitter/X provide valuable insights into the views of the general population.

In 2023, Bangladesh experienced its largest and deadliest outbreak of the Dengue virus (DENV), reporting the highest-ever recorded annual cases and deaths. Historically, most of the cases were recorded in the capital city, Dhaka. We aimed to characterize the geographical transmission of DENV in Bangladesh.

Background: Subclinical depressive symptoms increase the risk of developing Alzheimer's disease (AD). The neurobiological mechanisms underlying this link may involve stress system dysfunction, notably related to the hippocampus which is particularly sensitive to AD. We aimed to investigate the links between blood stress markers and changes in brain regions involved in the stress response in older adults with or without subclinical depressive symptoms.

Background: "Active" heat acclimation (exercise-in-the-heat) can improve exercise performance but the efficacy of "passive" heat acclimation using post-exercise heat exposure is unclear. Therefore, we synthesised a systematic review and meta-analysis to answer whether post-exercise heat exposure improves exercise performance.
Methods: Five databases were searched to identify studies including: (i) healthy adults; (ii) an exercise training intervention with post-exercise heat exposure via sauna or hot water immersion (treatment group); (iii) a non-heat exposure control group completing the same training; and (iv) outcomes measuring exercise performance in the heat (primary outcome), or performance in thermoneutral conditions, V̇Omax, lactate threshold, economy, heart rate, RPE, core temperature, sweat rate, and thermal sensations.

As plant-based diets gain traction, interest in their impacts on the gut microbiome is growing. However, little is known about diet-pattern-specific metagenomic profiles across populations. Here we considered 21,561 individuals spanning 5 independent, multinational, human cohorts to map how differences in diet pattern (omnivore, vegetarian and vegan) are reflected in gut microbiomes.

Effective targeting of somatic cancer mutations to enhance the efficacy of cancer immunotherapy requires an individualized approach. Autogene cevumeran is a uridine messenger RNA lipoplex-based individualized neoantigen-specific immunotherapy designed from tumor-specific somatic mutation data obtained from tumor tissue of each individual patient to stimulate T cell responses against up to 20 neoantigens. This ongoing phase 1 study evaluated autogene cevumeran as monotherapy (n = 30) and in combination with atezolizumab (n = 183) in pretreated patients with advanced solid tumors.

The impacts of climate change on human health are often underestimated or perceived to be in a distant future. Here, we present the projected impacts of climate change in the context of COVID-19, a recent human health catastrophe. We compared projected heat mortality with COVID-19 deaths in 38 cities worldwide and found that in half of these cities, heat-related deaths could exceed annual COVID-19 deaths in less than ten years (at + 3.

AG-270/S095033 is an oral, potent, reversible inhibitor of methionine adenosyltransferase 2 A (MAT2A), the enzyme primarily responsible for the synthesis of SAM. We report results from the first-in-human, phase 1 trial of AG-270/S095033 as monotherapy in patients with advanced malignancies (ClinicalTrials.

Objectives: To establish reference intervals (RIs) for work ability, at-work productivity loss and overall productivity loss in the general working population and to compare work ability and at-work productivity loss of patients with inflammatory rheumatic and musculoskeletal disease (iRMD) with this population.
Methods: Cross-sectional analysis among patients with iRMDs and population controls without iRMDs having paid work and participating in a Dutch cohort study. They reported on three work outcomes: work ability (0-10), at-work productivity loss and overall productivity loss (0%-100%).

Introduction: Primary sclerosing cholangitis (PSC) is the classical hepatobiliary manifestation of inflammatory bowel disease (IBD). The strong association between gut and liver inflammation has driven several pathogenic hypotheses to which the intestinal microbiome is proposed to contribute. Pilot studies of faecal microbiota transplantation (FMT) in PSC and IBD are demonstrated to be safe and associated with increased gut bacterial diversity.
