A systematic review found that while genomic classifier (GC) tests may influence risk classifications or treatment decisions for patients with localized prostate cancer (PCa), there is a need for better data on their cost-effectiveness, clinical utility, and their impact on racial and ethnic groups, particularly Black men. The study is published in Annals of Internal Medicine.
Prostate cancer is the most common cancer among men, with cases ranging from barely noticeable to highly aggressive ones requiring serious treatment. Determining who needs which type of treatment remains a significant challenge. Traditionally, clinicians rely on tools like the NCCN guidelines, which assess tumor stage, PSA levels, and Gleason grades. However, these tools are not perfect and can sometimes lead to overtreatment or undertreatment. Tests like Decipher by Veracyte, Prolaris by Myriad Genetics, and Oncotype DX Genomic Prostate Score (GPS) by MDx offer a genetic snapshot of tumor aggressiveness, potentially catching things that clinical tools might miss. Despite the potential of these tests, their use in clinical practice is inconsistent due to conflicting guidelines.
Researchers from the Department of Veterans Affairs reviewed 19 studies to assess the impact of these tissue-based genomic tests on risk stratification and treatment decisions for localized prostate cancer. The researchers analyzed test type, quality, population characteristics, risk reclassification and recommended and/or received treatment intensity and found that in low risk of bias observational studies, most patients with low or very low baseline risk did not see an increase in risk classification after GC testing. This pattern differed across GC test types, however, with GPS-based studies finding 0% - 11.9% of patients were reclassified to a higher risk category versus Decipher-based studies finding 12.8% to 17.1% reclassified to a higher risk category. In a randomized trial, reclassification to higher risk was more prevalent than in the observational studies examined. Observational studies indicated that GC testing often led to more patients opting for conservative management options like active surveillance.
The researchers note that the differences in results from observational and randomized trials emphasize the need for well-designed trials evaluating the impact of GC tests in management of PCa to inform patient-clinician decision-making.

The U.S. Department of Veterans Affairs (VA) and U.S Department of Defense (DoD) updated their 2019 clinical practice guideline (CPG) for the management of stroke rehabilitation to provide primary care providers with recommendations for the management of adult stroke patients. A summary of these guidelines relevant to internal medicine physicians and rehabilitation professionals is published in Annals of Internal Medicine.
Researchers developed 12 questions using the PICOTS (population, intervention, comparator, outcomes, timing of outcomes measurement, and setting) framework focusing on rehabilitation methods in the following areas: motor; cognitive, speech, or language; dysphagia; spasticity; mental or behavioral health; sensory rehabilitation; neglect; technology-assisted tools; settings and models of care; and caregiver support. To glean insights for these questions, they conducted a systematic review of studies published between July 2018 and May 2023. The key areas examined in the 2024 guideline are: transitions to community, motor therapy, dysphagia, aphasia, cognition, mental health, telehealth, and noninvasive brain stimulation.
To ease transitions to community for stroke patients, physicians can consider case management and psychosocial interventions. For motor therapy, evidence supports the implementation of task-specific practice, mirror therapy, rhythmic auditory stimulation, electrical stimulation and botulinum toxin for spasticity management. Chin tuck against resistance and respiratory muscle strength training can help manage issues relating to dysphagia, aphasia and cognition. To treat mental health conditions after a stroke, clinicians can consider selective serotonin reuptake inhibitors (SSRIs), psychotherapy and/or mindfulness-based therapies. Clinicians should also consider an interdisciplinary team-based approach to stroke rehabilitation and use these guidelines as a supplement to the Guidelines for Adult Stroke Rehabilitation and Recovery from the American Heart Association and American Stroke Association.

KERI, overcomes the biggest challenge of the lithium–sulfur battery, the core of UAM
2025-01-20
Dr. Park Jun-woo's team at KERI's Next Generation Battery Research Center has overcome a major obstacle to the commercialization of next-generation lithium–sulfur batteries and successfully developed large-area, high-capacity prototypes.
The lithium–sulfur battery, composed of sulfur as the cathode (+) and lithium metal as the anode (-), has a theoretical energy density more than eight times that of lithium-ion batteries, demonstrating significant potential. Additionally, it uses abundant sulfur (S) instead of expensive rare earth elements, making it cost-effective and environmentally ...
In chimpanzees, peeing is contagious
2025-01-20
A new study reported in the Cell Press journal Current Biology on January 20 is the first to describe a phenomenon researchers refer to as “contagious urinations.” The study in 20 captive chimpanzees living at the Kumamoto Sanctuary in Japan shows that, when one chimp pees, others are more likely to follow.
“In humans, urinating together can be seen as a social phenomenon,” says Ena Onishi of Kyoto University.
“An Italian proverb states, ‘Whoever doesn’t pee in company is either a thief or a spy’ (Chi non piscia in compagnia o è ...
Scientists uncover structure of critical component in deadly Nipah virus
2025-01-20
Scientists at Harvard Medical School and Boston University Chobanian & Avedisian School of Medicine have mapped a critical component of the Nipah virus, a highly lethal bat-borne pathogen that has caused outbreaks in humans almost every year since it was identified in 1999.
The advance, described Jan. 20 in Cell, brings scientists a step closer to developing much-needed medicines. Currently, there are no vaccines to prevent or mitigate infection with the Nipah virus and no effective treatments for the disease ...
Study identifies benefits, risks linked to popular weight-loss drugs
2025-01-20
Demand for weight-loss medications sold under brand names such as Ozempic and Wegovy continues to surge, with a recent study reporting one in eight Americans has taken or is currently using the drugs to treat diabetes, heart disease or obesity.
Formally, these drugs are known as glucagon-like peptide-1 receptor agonists (GLP-1RA) and include Mounjaro and Zepbound. Informally, media, patients and even some physicians have dubbed GLP-1 medications as “miracle drugs” because of the profound weight loss among users. While these health benefits are well established, information is sparse on the drugs’ effects across ...
Ancient viral DNA shapes early embryo development
