Legalizing youth-friendly cannabis edibles and extracts and adolescent cannabis use

JAMA Network Open

2025-04-18

(Press-News.org) About The Study: In this serial cross-sectional study of adolescents in grades 7 to 11, legalization of cannabis edibles and extracts was associated with an increase not only in edible cannabis use and cannabis smoking, but also in the overall prevalence of cannabis use and co-use of alcohol and cannabis, highlighting the need for stricter policy measures to curb adolescents’ access to cannabis edibles and extracts and greater awareness among adolescents about harms of cannabis use.

Medical debt and forgone mental health care due to cost among adults

2025-04-18

About The Study: In this survey study, more than 1 in 7 adults reported carrying medical debt in 2023, of whom 1 in 3 forwent mental health care in the subsequent year. Medical debt may exacerbate the treatment gap by potentially (1) raising the threshold for seeking care, (2) eroding patient trust in the health system, or (3) being denied care due to outstanding debts.

Colder temperatures increase gastroenteritis risk in Rohingya refugee camps

2025-04-18

Colder temperatures are linked with increased risk of diarrhea among Rohingya refugees in Bangladesh, emphasizing the need for climate-sensitive health strategies in refugee settings. A new study by scientists at Hokkaido University has found that lower temperatures significantly increase the risk of gastroenteritis among Rohingya refugees living in Bangladesh’s Kutupalong and Nayapara camps. Gastroenteritis is a viral or bacterial infection that causes inflammation of the stomach and intestines, resulting in ...

Acyclovir-induced nephrotoxicity: Protective potential of N-acetylcysteine

2025-04-18

Background and objectives Oxidative stress could be a key process in acyclovir (ACV)-induced nephrotoxicity. N-acetylcysteine (NAC) is a water-soluble antioxidant with anti-inflammatory activity. This study aimed to evaluate the protective effect of NAC on ACV-induced nephrotoxicity in adult Wistar rats. Methods Forty adult male Wistar rats (200–220 g) were used. The rats were randomly divided into eight groups (n = 5/group) and were treated intraperitoneally daily for seven days as follows: Group 1 (Control) was administered water (0.2mL), while groups 2–4 were administered NAC (25, 50, and 100 mg/kg). Group 5 was administered ACV (150 mg/kg), while ...

Inhibition of cyclooxygenase-2 upregulates the nuclear factor erythroid 2-related factor 2 signaling pathway to mitigate hepatocyte ferroptosis in chronic liver injury

2025-04-18

Background and Aims Ferroptosis plays an essential role in chronic liver diseases, and cyclooxygenase-2 (COX-2) affects liver fibrosis through multiple mechanisms. However, research on COX-2 regulation of ferroptosis in chronic liver injury remains limited. This study aimed to investigate whether and how COX-2 regulates ferroptosis in chronic liver injury. Methods In vivo, a thioacetamide (TAA)-induced chronic liver injury model, characterized by significant liver lipid peroxidation and oxidative stress, was used. COX-2+/+ and COX-2–/– mice ...

Mapping minds: The neural fingerprint of team flow dynamics

2025-04-18

Summary: A collaborative study by researchers from Toyohashi University of Technology and California Institute of Technology (Caltech) introduces a groundbreaking algorithm that maps individual brain activity in a multi-dimensional space. This “neural fingerprint” reveals stable, long-term neural traits that interplay with transient brain states during social interactions. The study demonstrates that individuals whose neural fingerprints are more aligned tend to more readily enter a shared state of deep focus—commonly known as team flow—which has profound implications for enhancing teamwork ...

Patients support AI as radiologist backup in screening mammography

2025-04-18

OAK BROOK, Ill. – The results of a large survey from a diverse patient population revealed cautious support for artificial intelligence (AI) implementation in screening mammography, according to a study published today in Radiology: Imaging Cancer, a journal of the Radiological Society of North America (RSNA). Personal medical history and sociodemographic factors influenced respondent’s level of trust in AI. While the diagnostic accuracy of AI systems has drastically improved in recent ...

Existing drug has potential for immune paralysis

2025-04-18

When the immune system does not function properly, individuals become more susceptible to infections caused by viruses, bacteria, or fungi. Researchers from Radboud university medical center have demonstrated that an existing drug can revive immune cells that are not functioning correctly. These findings provide leads for further research in patients admitted to the intensive care unit (ICU) with sepsis. Twenty percent of global deaths are associated with sepsis, and it is the leading cause of death in ICUs. Sepsis is characterized by organ failure, for instance of the kidneys or lungs, caused by a dysregulated immune response to an infection. Patients with ...

Soft brainstem implant delivers high-resolution hearing

2025-04-18

Over the last couple of decades, many people have regained hearing functionality with the most successful neurotech device to date: the cochlear implant. But for those whose cochlear nerve is too damaged for a standard cochlear implant, a promising alternative is an auditory brainstem implant (ABI). Unfortunately, current ABIs are rigid implants that do not allow for good tissue contact. As a result, doctors commonly switch off a majority of the electrodes due to unwanted side effects such as dizziness or facial twitching—leading most ...
