Navigating the Gap: An Examination of Funder Rhetoric and Reality Regarding Community‐Research Partnerships

Drug and Alcohol Review, Volume 45, Issue 1, January 2026.
ABSTRACT Partnerships between researchers and consumers—specifically, people who use drugs in the context of our research co‐production—can significantly enhance the relevance and impact of research. Funders increasingly emphasise the value of community‐researcher collaborations, yet translating this commitment into effective practice remains ...

Mass of Cepheid V350 Sgr Incorporating Interferometry and the Companion Mass

The Astrophysical Journal
The system V350 Sgr has a classical Cepheid for the primary. Interferometry is presented for the system, and the full orbit is determined. The mass of the companion has been determined from an International Ultraviolet Explorer spectrum and comparison ...

TYC 1031 01262 1: The First Known Galactic Eclipsing Binary with a Type II Cepheid Component

, 2007
We present the discovery and CCD observations of the first eclipsing binary with a Type II Cepheid component in our Galaxy. The pulsation and orbital periods are found to be 4.1523 and 51.38 days, respectively, i.e.

Impact of Real‐Time, On‐Demand Influenza and Respiratory Syncytial Virus Testing at Point‐of‐Care on Antibiotic Prescribing and Clinical Outcome in Pediatric Outpatients With Acute Respiratory Illness: A Prospective, Quasi‐Randomized, Controlled Study

Influenza and Other Respiratory Viruses, Volume 20, Issue 1, January 2026.
ABSTRACT Background Rapid and accurate detection and identification of viral pathogens have an impact on physician decision‐making for patients with acute respiratory illness (ARI). We aimed to evaluate the Xpert Xpress Flu/RSV test for the management of antibiotic prescribing in pediatric outpatients with ARI. Methods We performed a prospective, quasi‐

Decentralised Hepatitis C Management: A Simplified, Integrated Model of Care in a Primary Health Centre in Pakistan, August 2022–June 2023

Journal of Viral Hepatitis, Volume 33, Issue 1, January 2026.
ABSTRACT Pakistan has the world's highest hepatitis C virus (HCV) prevalence, yet access to HCV care remains limited. In collaboration with the Ministry of Health Sindh, Médecins Sans Frontières implemented a simplified, decentralised model for HCV screening and treatment at a government‐run primary health centre (PHC) in Baldia Town, Karachi, Pakistan.

The anomalous Cepheid XZ Ceti

, 2006
XZ Ceti is the only known anomalous Cepheid in the Galactic field. Being the nearest and brightest such variable star, a detailed study of XZ Ceti may shed light on the behaviour of anomalous Cepheids whose representatives have been mostly detected in ...

Newly Diagnosed Crohn’s Disease After SARS‐CoV‐2 Infection

Case Reports in Gastrointestinal Medicine, Volume 2026, Issue 1, 2026.
Coronavirus disease 2019 (COVID‐19) is known to induce gastrointestinal symptoms as well as respiratory symptoms. There have been instances where diarrhea persists after the acute phase of COVID‐19, suggesting an extension of the disease’s symptoms. It is not typical to recall the onset of inflammatory bowel disease (IBD) with such symptoms, much less ...
