Noninvasive Mechanical Ventilation Is a Promising Way to Improve Lung Cancer Radiation Therapy.

Purpose: Accurate radiation therapy (RT) for lung cancer is challenging because of the respiratory motion of the tumor and surrounding organs at risk. Recently, non-invasive mechanical ventilation (NIMV) has been investigated as a novel respiratory motion management strategy. Using NIMV, respiratory motion can be minimized, while a larger lung volume yields less overall lung dose.

Diverse phenotypes, consistent treatment: a study of 30,997 South Asian and White IBD patients using the UK IBD BioResource.

Objective: To evaluate South Asian (SA) and White (WH) inflammatory bowel disease (IBD) phenotypes, and to explore treatment approach variations between these cohorts in the UK using the IBD BioResource database.

Design: Differences between WH and SA IBD patients were analysed using demographic, phenotypic and outcome data. Drug utilisation patterns and surgical outcomes were assessed in propensity score-matched (PSM) cohorts with multivariable logistic regression, Cox regression and Kaplan-Meier analysis.

Anisotropy parameters from shapes of ion-ion correlation features of fragmenting molecules.

When a molecule loses two electrons, Coulomb repulsion makes the resulting doubly charged system likely to fragment into two singly charged ions. These monocations can be detected in a correlated fashion using multiplex time-of-flight spectroscopy. The island shapes in the ion-ion coincidence maps derived from such two-body dissociations contain detailed information on the physical processes underlying the fragmentation.

Ultrafast photochemical processes in 1,2-dichloroethene measured with a universal XUV probe.

The presence of two chlorine atoms in 1,2-dichloroethene allows for isomerization around the double bond. This isomerization can lead to rich photochemistry. We present a time-resolved pump-probe photoelectron spectroscopy measurement on both the - and - isomers of 1,2-dichloroethene.

Patients and clinicians have different priorities when discussing pain in the IBD clinic.

Objective: Pain in inflammatory bowel disease (IBD) is frequently neglected/overlooked, particularly in ulcerative colitis, and communication about pain can be suboptimal. The current study juxtaposes clinicians' conceptualisations of patients' pain with patient narratives. The aim was to inform the development of a pain reporting tool and provide guidance for better communication about IBD pain.

Dynamic prediction of pregnancy outcome after previous stillbirth or perinatal death: pilot study to establish proof-of-concept and explore method feasibility.

Objective: To establish proof-of-concept for the dynamic prediction of adverse pregnancy outcome in women with a history of stillbirth or perinatal death, repeatedly throughout the pregnancy.

Methods: A retrospective cohort study of women in a subsequent pregnancy following previous perinatal loss, who received antenatal care at a tertiary hospital between January 2014 and December 2017, was used as the basis for exploratory prognostic model development. Models were developed to repeatedly predict a composite adverse outcome (stillbirth or neonatal death, 5-min Apgar score < 7, umbilical artery pH ≤ 7.

Remote monitoring of rheumatoid arthritis (REMORA): study protocol for a stepped wedge cluster randomized trial and process evaluation of an integrated symptom tracking intervention.

Background: Management of rheumatoid arthritis (RA) relies on symptoms reported by patients during infrequent outpatient clinic visits. These reports are often incomplete and inaccurate due to poor recall, leading to suboptimal treatment decisions and outcomes. Asking people to track symptoms in-between visits and integrating the data into clinical pathways may improve this.

Differences in the Adverse Event Burden of Corticosteroid Use in Inflammatory Bowel Disease as Reported Between Adverse Event Reporting Systems and a Patient Questionnaire.

Background And Aims: Corticosteroids are widely used in managing inflammatory bowel disease [IBD]. While adverse events [AEs] of corticosteroids are well recognised, current understanding of corticosteroid-related AE burden in IBD remains incomplete.

Methods: AE reports for prednisone/prednisolone and budesonide were extracted from the Food and Drug Administration Adverse Event Reporting System [FAERS] and VigiBase databases.

Factors associated with chronic abdominal pain in patients with inflammatory bowel disease in remission: A pilot cross-sectional study.

Background: Patients (20%-50%) with inflammatory bowel disease (IBD) experience chronic abdominal pain during remission. The clinical features of IBD patients with abdominal pain during remission remain poorly characterized. This cross-sectional pilot study aimed to assess patient recruitment, adherence, and feedback to optimize questionnaires for future use and to determine the clinical features that distinguish IBD patients in remission with and without abdominal pain.

Predicting Adverse Events to Thiopurines in IBD: Are We a Step Closer?

Thiopurines remain an important option in the treatment of IBD. However, the unpredictable and sometimes serious side effects and intolerance remain a major challenge. Pretreatment of extended genetic panel analysis, identification of novel variants, and monitoring of intermediate metabolites will help improve the overall outcome and reduce the toxicity.

Preparation of Tautomer-Pure Molecular Beams by Electrostatic Deflection.

Tautomers are ubiquitous throughout chemistry and typically considered inseparable in solution. Yet (bio)chemical activity is highly tautomer-specific, with common examples being the amino and nucleic acids. While tautomers exist in an equilibrium in solution, in the cold environment of a molecular beam the barrier to tautomerization is typically much too high for interconversion, and tautomers can be considered separate species.

Coming together as a whole: lessons from connecting across sectors, cultures, and contexts to elevate efforts for planetary health.

Background: Addressing complex and interconnected ecological, social, and health issues necessitates upstream, solutions-oriented, and whole-systems thinking. Specifically, exploring what it means to live in reciprocity with the planet and all living systems, now and for generations to come, can have a crucial role in advancing planetary health.

Methods: In this presentation, we show findings from four gatherings that we co-designed and co-hosted to connect communities, lands, waters, climate, and health.

Defining predictors of responsiveness to advanced therapies in Crohn's disease and ulcerative colitis: protocol for the IBD-RESPONSE and nested CD-metaRESPONSE prospective, multicentre, observational cohort study in precision medicine.

Introduction: Characterised by chronic inflammation of the gastrointestinal tract, inflammatory bowel disease (IBD) symptoms including diarrhoea, abdominal pain and fatigue can significantly impact patient's quality of life. Therapeutic developments in the last 20 years have revolutionised treatment. However, clinical trials and real-world data show primary non-response rates up to 40%.

Assessing 'response' to the low-FODMAP diet in irritable bowel syndrome: Should we be reporting harder primary endpoints?

Background & Aims: The low-FODMAP diet (LFD) has become almost synonymous with IBS care, yet the challenges associated with this rigorous therapeutic approach are often underacknowledged. Despite positive outcomes in RCTs, comparator groups frequently exhibit substantial response rates, raising questions about the definition of 'response'. Whilst the assessment of response in drug trials has evolved to utilize the more stringent FDA/EMA primary clinical endpoints, trials of the LFD have not yet followed.
