(Press-News.org) Background and Goal: Chest pain is a common but challenging symptom for general practitioners to evaluate, as it can be caused by both serious conditions and more benign issues. This study assessed the effectiveness of various risk stratification tools, including clinical decision rules and troponin tests, in helping general practitioners rule out acute coronary syndrome in patients with chest pain.
Study Approach: Researchers conducted a systematic review of studies involving adult patients presenting with chest pain in primary care settings. The review included studies that examined the diagnostic accuracy of different clinical decision rules and troponin point-of-care tests, both conventional and high-sensitivity, in identifying acute coronary syndrome, which includes heart attacks. The study compared these tools to the unaided clinical judgment of general practitioners.
Main Findings: 14 studies were included in the final review.
• Some of the clinical decision rules without troponin improved safety. However, none consistently outperformed unaided general practitioner judgment in ruling out acute coronary syndrome.
• Conventional troponin as a standalone test did not meet the desired diagnostic accuracy, making the tests less reliable in primary care settings.
• High-sensitivity troponin tests demonstrated the highest diagnostic accuracy. However, this finding requires further prospective validation in primary care before it can be recommended for widespread use.
Why It Matters: Although high-sensitivity troponin tests hold promise, they are not yet ready to replace clinical judgment or be used independently in primary care settings without further validation.

Family Physicians in Rural Hospitals Associated With Lower Cesarean Rates and Safer Maternal Care Culture
Background and Goal: The U.S. is experiencing a maternal health crisis, particularly in rural areas. This issue is compounded by rising rates of severe maternal morbidity and mortality. Family physicians often fill critical gaps in care in rural areas where obstetricians are scarce. This study examined how the presence of family physicians in rural hospitals impacts cesarean delivery rates and the overall quality of care during childbirth.
Study Approach: The study analyzed data from rural ...
Risk model identifies advanced cancer trial patients at highest risk for acute care use
2024-09-23
Investigators from the SWOG Cancer Research Network have developed and validated a risk prediction model for identifying which patients with advanced cancer who are enrolled to clinical trials are at highest risk for unplanned emergency room (ER) visits and hospital stays.
Determining which patients are at significantly higher risk could inform interventions to reduce the need for such visits, improving care quality and reducing costs.
The work will be delivered as an oral presentation by Dawn L. Hershman, MD, MS, at the 2024 ASCO Quality Care Symposium, which will ...
Robust family medicine residency programs help residents meet scholarly output requirements
2024-09-23
Background and Goal: Family medicine residency programs are essential for training future primary care physicians. The Accreditation Council for Graduate Medical Education (ACGME) program requires family medicine residents to perform two scholarly projects. One must be a quality improvement project, and the second project type is at the program's discretion. This study assessed the scholarly activity output of family medicine residency programs in the U.S., identified institutional factors associated with increased scholarly ...
Using transparent capsules in dry powder inhalers could significantly improve medication delivery
2024-09-23
Background and Goal: This study examined whether patients with non-reversible chronic airway disease using a transparent capsule in single-dose dry powder inhalers affects the amount of medication delivered. The goal was to determine if patients who use transparent capsules that allow them to see if the medication has been fully inhaled have better inhalation results compared to those using opaque capsules.
Study Approach: Researchers conducted an observational cross-sectional study between October 2020 and October ...
Family physicians in rural hospitals associated with lower cesarean rates and safer maternal care culture
2024-09-23
Background and Goal: The U.S. is experiencing a maternal health crisis, particularly in rural areas. This issue is compounded by rising rates of severe maternal morbidity and mortality. Family physicians often fill critical gaps in care in rural areas where obstetricians are scarce. This study examined how the presence of family physicians in rural hospitals impacts cesarean delivery rates and the overall quality of care during childbirth.
Study Approach: The study analyzed data from rural hospitals in Iowa and collected survey responses from clinicians about their attitudes and practices related to ...
Long COVID patients seek better collaboration with health care professionals
2024-09-23
Background and Goal: “Long COVID” is the continuation or development of new symptoms three months after initial SARS-CoV-2 infection. For many patients with long COVID, primary care is the first point of interaction with the health care system. This study aimed to examine the expectations and experiences of primary care patients seeking treatment for long COVID.
Study Approach: Researchers conducted 20 semistructured interviews between 2022 and 2023 with primary care patients from a ...
EHR messaging before first visit fosters a stronger patient-physician connection
2024-09-23
Inspired by the VA’s My Life, My Story project, this initiative used the Electronic Health Record (EHR) to strengthen the patient-physician relationship. The initiative invited patients to share personal narratives before their first visit with a new primary care physician. Conducted at a regional clinic affiliated with the University of Wisconsin-Madison, the project involved sending secure messages to patients, asking them to describe what they wanted their health care team to know about them as a person. The majority of patients responded ...
SETI AIR announces Cosmic Consciousness residency recipients

September 23, 2024, Mountain View, CA – The SETI Institute's AIR program announced the recipients of its Cosmic Consciousness residency for mid-career and emerging artists:
Open (Mid-Career) category: The recipients are the artist team of Bart Kuipers, Julie Michele Morin, and daniela brill estrada, with their project Exoplanet Poetry. The artists plan to create a book of poems using an AI trained on chemical data from imagined extraterrestrial sources. The book will be presented as a multi-sensory chemical experience, making ...
Australian crater could offer fresh insight into Earth’s geological history
2024-09-23
A probable crater stretching more than 370 miles, or 600 kilometers, across the heart of Australia could reshape our understanding of Earth’s geological history.
Researcher Daniel Connelly and Virginia Commonwealth University’s Arif Sikder, Ph.D., believe they have found evidence to support the existence of MAPCIS – the Massive Australian Precambrian-Cambrian Impact Structure -– which is a nonconcentric complex crater that could provide new insights into the geological and biological evolution of our planet.
“Working on the MAPCIS project has been an incredible journey,” said Sikder, an associate professor in the Center for ...
New study raises questions about validity of standard model of solar flares
2024-09-23
Solar flares are extremely intense events that occur in the Sun’s atmosphere, lasting anywhere from a few minutes to several hours. According to the standard flare model, the energy that triggers these explosions is transported by accelerated electrons that hurtle from the magnetic reconnection region in the corona to the chromosphere. As the electrons collide with the chromospheric plasma, they deposit their energy in the plasma, which is heated and ionized as a result. They also cause intense radiation in several ...
