RESEARCH SUMMARY
Study highlights the importance of infection prevention after CAR-T cell therapy
Study Title: A systematic review and meta-analysis of nonrelapse mortality after CAR T cell therapy
Publication: Nature Medicine
Dana-Farber Cancer Institute authors: David M. Cordas dos Santos, MD, Irene M. Ghobrial, MD, Jean-Baptiste Alberge, PhD
Summary: Researchers at Dana-Farber Cancer Institute, in collaboration with colleagues from Memorial Sloan Kettering Cancer Center in New York (Dr. Kai Rejeski) and the LMU Hospital in Munich, Germany (Dr. Tobias Tix), have found that infections were the main driver of non-relapse mortality in patients receiving chimeric antigen receptor (CAR) T cell therapy. The team analyzed reports from 7604 patients across 18 clinical trials and 28 real world studies. Infections accounted for half of all reported non-relapse related deaths. Other cancers were the second most common driver at 7.8%. Cardiovascular or respiratory events were third, at 7.3%. Side effects specific to CAR-T cell therapy, such as cytokine release syndrome and neurotoxicity, played a minor role. Importantly, the researchers found non-relapse mortality to be associated with the underlying disease entity and certain CAR T-cell products, even when accounting for key study features.
Significance: Much attention has been paid to the risks associated with CAR-T cell therapy and managing CAR-T cell therapy specific side effects, such as cytokine release syndrome and neurotoxicity. This study reveals that infections play a critical role in non-relapse related death and suggests a pressing need for comprehensive, evidence-based guidelines that inform infection prevention and management after CAR-T cell therapy.

A revised version of the Sexual Experiences Survey – Victimization (SES-V), the gold standard measurement of sexual exploitation designed for adults over age 18, has been released in a special issue of the Journal of Sex Research.
As the first revision since 2007, the new SES-V is an interdisciplinary collaboration among experts across more than 10 U.S. universities and the Kinsey Institute, led and coordinated by Dr. Mary Koss from the University of Arizona. It adopts more inclusive language and ...

An exoplanet infamous for its deadly weather has been hiding another bizarre feature—it reeks of rotten eggs, according to a new Johns Hopkins University study of data from the James Webb Space Telescope.
The atmosphere of HD 189733 b, a Jupiter-sized gas giant, has trace amounts of hydrogen sulfide, a molecule that not only gives off a stench but also offers scientists new clues about how sulfur, a building block of planets, might influence the insides and atmospheres of gas worlds beyond the solar system.
The findings are published today ...

Vaccinating mothers against respiratory syncytial virus (RSV) during late pregnancy to protect their newborns is not associated with an increased risk of preterm birth or other poor outcomes, according to a study by Weill Cornell Medicine and NewYork-Presbyterian investigators. Infants are particularly vulnerable to the virus which can cause a serious lower respiratory illness.
The study published in JAMA Network Open on July 8 adds real-world evidence to the existing data from clinical trials about the safety of Pfizer’s Abrysvo vaccine. The researchers found that there ...

KEY TAKEAWAYS
After implementing a new hospice transition program, 210 out of 388 patients (54.1 percent) at Brigham and Women’s Hospital transitioned to hospice from the emergency department (ED) within 96 hours, compared to 61 of 270 patients (22.1 percent) in the control period.
Across all groups, the presence of a Medical Order for Life-Sustaining Treatment plan (MOLST), was independently associated with hospice transition.
These findings suggest that hospice transition programs can help improve use of hospice for patients presenting at the ED near the end ...

About The Study: Although total dietary quality scores among U.S. children improved overall during 2005-2020, the increase remained suboptimal: lower than 5 points, a significant threshold for children in this analysis of changes in diet quality.

About The Study: Survey respondents reported substantial acceptability of hospital-at-home care, which did not vary across sociodemographics, health insurance coverage, health status, prior hospitalizations, or telehealth use. Approximately half of respondents agreed that hospital-at-home care was effective, safe, and convenient. Most indicated capacity to perform many caregiver tasks.

In 2020, suicide ranked as the third leading cause of death for adults aged 18 to 20 years in the United States. Firearms were implicated in approximately half of these cases, and by 2017, they had surpassed motor vehicles as the leading cause of death in this age group. While ongoing debates on gun violence and mental health have increased public support for restricted firearm access, not much is known about the impact of gun control policies on young adults.
To fill this knowledge gap, a recent study published in the August issue of the American Journal of Public Health on July 03, ...

Fukuoka, Japan —The climate crisis is hitting home with more frequent extreme weather events. Companies, particularly those in high-emission industries, are major contributors to global carbon emissions, therefore making them key players in the fight against climate change. Recognizing this responsibility, many businesses are now taking proactive measures to reduce their carbon footprint, by reducing carbon emissions and transparently sharing their environmental strategies and data.

CLEVELAND—There’s only one U.S. Food and Drug Administration-approved therapy for an inherited retinal disease, and dozens of retinitis pigmentosa (RP) genes for which no therapy is available.
With a new three-year, $1.5 million grant from the Foundation Fighting Blindness, Shigemi Matsuyama, an associate professor of ophthalmology and visual sciences at the Case Western Reserve University School of Medicine, will test a possible breakthrough drug that can be taken by mouth—one that may address many RP disease manifestations, regardless of the underlying genetic mutation.
“We believe it can serve as the basis of an oral medicine to prevent blindness in RP ...
