Point of care molecular diagnostics benefits from a portable battery-operated device capable of performing a fast turnaround using reliable inexpensive cartridges. We describe a prototype device for performing a molecular diagnostics test for clinical and biodefense samples in 16 minutes using a prototype capable of an 8 minute PCR reaction, followed by hybridization and detection on an electrochemical microarray based on the i-STAT® system. We used human buccal swabs for hemochromatosis testing including in-device DNA extraction. Additional clinical and biodefense samples included influenza A and bacterial select agents Bacillus anthracis, Yersinia pestis and Francisella tularensis.

Pericardial effusion refers to the accumulation of fluid within the pericardial sac, the double-layered membrane surrounding the heart. It can be caused by various medical conditions and may lead to serious complications if not diagnosed and managed promptly. Point-of-care ultrasound (POCUS) has emerged as a valuable tool in the clinical evaluation of pericardial effusions, offering real-time visualization and aiding in the assessment of its size, characteristics, and potential hemodynamic impact.

Clinical endpoints, such as overall survival, directly measure relevant outcomes. Surrogate endpoints, in contrast, are intermediate, stand-in measures of various tumour-related metrics and include tumour growth, tumour shrinkage, blood results, etc. Surrogates may be a time point measurement, that is, tumour shrinkage at some point (eg, response rate) or biomarker-assessed disease status, measured at given time points (eg, circulating tumour DNA, ctDNA).

Objective: Anxiety is common among patients attending an initial oncology consultation. The objective of this trial was to test if an enhanced compassion video emailed to patients prior to their initial oncology consultation reduces anxiety compared with being sent an information-only introduction video.

Methods And Analysis: We conducted a randomised control trial at a single university-based cancer centre between May 2021 and October 2023.

Transgender and gender-diverse (TGD) individuals face an elevated risk of cancer in comparison with the general population. This increased risk is primarily attributed to an imbalanced exposure to modifiable risk factors and a limited adherence to cancer screening programmes, stemming from historical social and economic marginalisation. Consequently, these factors contribute to poorer clinical outcomes in terms of cancer diagnosis and mortality.

Background: Recruiting and retaining International Medical Graduates (IMGs) has been identified as a key component in addressing the ongoing workforce crisis in general practice. However, research shows IMG General Practitioners (GPs) face unique challenges compared to their UK-trained counterparts, impacting their welfare, retention in the workforce, and ability to provide patient care.

Aim: This study examined the challenges facing early-career IMG GPs, the help and support they access and want to access, and their perceptions and utilisation of the help and support available.
