COVID-19 vaccine reactogenicity among young children

JAMA Network Open

2024-11-25

(Press-News.org) About The Study: No unexpected reactions were identified in this analysis of reactions to COVID-19 vaccines among children. Similar to this study, data from clinical trials and V-safe found that irritability was the most common systemic reaction among children ages 6 months to younger than 2 years, followed by fever and fatigue or sleepiness. In contrast to other studies observing a higher prevalence of reactions after the second COVID-19 vaccine dose, this study observed a higher prevalence after the first dose. This difference may reflect maternal vaccination; the first COVID-19 vaccination in this cohort may be some children’s second immunological encounter with a COVID-19 vaccine.

Generalizability of clinical trials of novel weight loss medications to the US adult population

2024-11-25

About The Study: This study estimates that approximately one-third of U.S. adults without diabetes who were eligible for weight loss treatment with glucagon-like peptide 1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GLP-1/GIP) were excluded from clinical trials supporting these medications’ safety and effectiveness. Until there is evidence from high-quality postmarketing studies, the FDA should consider updating labeling to advise caution on generalizing the safety and effectiveness of GLP-1 and GLP-1/GIP to populations excluded from pivotal trials.

Wildfire smoke exposure and incident dementia

2024-11-25

About The Study: In this cohort study, after adjusting for measured confounders, long-term exposure to wildfire and non-wildfire fine particulate matter (PM2.5) over a 3-year period was associated with dementia diagnoses. As the climate changes, interventions focused on reducing wildfire PM2.5 exposure may reduce dementia diagnoses and related inequities.

Health co-benefits of China's carbon neutrality policies highlighted in new review

2024-11-25

Researchers from the National Institute of Health Data Science at Peking University have conducted a comprehensive review of the health impacts of China's carbon mitigation strategies. Published in Health Data Science, this review emphasizes the significant health co-benefits of environmental policies aimed at reducing greenhouse gas emissions in China, the world's largest carbon emitter. These benefits include reducing deaths and diseases related to air pollution, particularly from PM2.5 and ozone (O3), as well as mitigating climate-related ...

Key brain circuit for female sexual rejection uncovered

2024-11-25

A team from the Champalimaud Foundation (CF) has pinpointed a critical neural circuit for sexual rejection, identifying a set of brain cells that play a crucial role in determining whether a female accepts or rejects mating attempts based on her reproductive cycle. Their findings, published today in Neuron, deepen our understanding of how the brain regulates social and reproductive behaviours. Female mammals, such as rodents, accept mating attempts only during their fertile phase, and actively reject males outside this period. While the brain areas controlling sexual receptivity are well-studied, the mechanisms behind active rejection ...

Electrical nerve stimulation eases long COVID pain and fatigue

2024-11-25

A wearable electrical nerve stimulation device can provide relief to people experiencing the persistent pain and fatigue linked to long COVID, a study co-led by UCLA and Baylor College of Medicine researchers suggests. Long-COVID, a complex and lingering condition following COVID-19 recovery, affects approximately 1 in 13 adults in the U.S. Symptoms such as widespread pain, fatigue, and muscle weakness often continue to disrupt daily activities, including walking and basic tasks. The study, published in the peer-reviewed Nature Scientific Reports, focused on a wearable Transcutaneous Electrical Nerve Stimulation ...

ASTRO issues update to clinical guideline on radiation therapy for rectal cancer

2024-11-25

ARLINGTON, Va., November 25, 2024 — The American Society for Radiation Oncology (ASTRO) issued today an updated clinical guideline for physicians who use radiation therapy to treat patients with locally advanced rectal cancer. This update incorporates new data on patient selection and best practices from several practice-changing clinical trials published since the prior guideline was issued in 2020. The updated ASTRO guideline is published in Practical Radiation Oncology. Colorectal cancer is the leading cause of cancer deaths for Americans aged 20 to 49 and the second most common cause of cancer-related death overall. In the U.S., the incidence of early ...

Researchers develop tools to examine neighborhood economic effects on spinal cord injury outcomes

2024-11-25

East Hanover, NJ – November 25, 2024 – Kessler Foundation researchers have developed robust measures of neighborhood economic factors to study how social determinants influence health outcomes after spinal cord injury (SCI). The study reveals that individuals in disadvantaged neighborhoods face higher risks of poor health, emphasizing the need for public policy to address environmental inequities. Research scientists developed and validated two composite measures – neighborhood socioeconomic ...

Case Western Reserve University awarded $1.5 million to study vaginal bacterial linked to serious health risks

2024-11-25

CLEVELAND—Bacterial vaginosis (BV), the most prevalent condition affecting the female reproductive system in women aged 15 to 44, is linked to such serious health risks as preterm birth, gynecological malignancies and sexually transmitted diseases. But effective long-term treatments for BV are limited: More than half experience a recurrence within six months, according to several studies. With a $1.5 million grant from the National Institutes of Health (NIH), researchers at the Case Western Reserve School of Medicine will study the dynamics of BV in hopes of identifying a more effective approach. “We hope to gain insights into promoting ...

The next evolution of AI begins with ours

2024-11-25

In a sense, each of us begins life ready for action. Many animals perform amazing feats soon after they’re born. Spiders spin webs. Whales swim. But where do these innate abilities come from? Obviously, the brain plays a key role as it contains the trillions of neural connections needed to control complex behaviors. However, the genome has space for only a small fraction of that information. This paradox has stumped scientists for decades. Now, Cold Spring Harbor Laboratory (CSHL) Professors Anthony Zador and Alexei Koulakov have devised a potential solution using artificial intelligence. When Zador first encounters this problem, he puts a ...
