Officer-involved killings of unarmed black people and racial disparities in sleep health

2024-02-05

About The Study: Sleep duration among Black survey respondents worsened after exposure to officer-involved killings of unarmed Black individuals in their area of residence. The findings were specific to officer involved killings of unarmed Black people, and no adverse outcomes on sleep health were found for white respondents. These findings underscore the role of structural racism in shaping racial disparities in sleep health. Authors: Atheendar S. Venkataramani, M.D., Ph.D., of the University ...

Injuries from legal interventions involving conducted energy devices

2024-02-05

About The Study: This study of emergency department visits for physical injuries from use of conducted energy devices, such as TASERs, by police departments found that most visits involved young Black and white males from low-income areas. Black individuals were overrepresented in the sample versus the U.S. population, consistent with research demonstrating increased risk of police violence in Black populations. Authors: Kevin N. Griffith, Ph.D., of the Vanderbilt University Medical Center ...

Losing sleep over killings of unarmed Black individuals by police

2024-02-05

PHILADELPHIA – Black adults across the United States suffer from sleep problems following exposure to news about unarmed Black individuals killed by police during police encounters, according to new findings published today in JAMA Internal Medicine from researchers at the University of Pennsylvania Perelman School of Medicine. The issue, researchers said, may compound the risk factors that poor sleep already poses for many chronic and mental health conditions, from depression to post traumatic stress disorder. Researchers conducted two separate analyses examining changes in sleep duration in the U.S. non-Hispanic Black population before and after exposure to such deaths ...

New technology unscrambles the chatter of microbes

2024-02-05

Researchers from University of California San Diego, as part of a large collaboration with scientists around the world, have developed a new search tool to help researchers better understand the metabolism of microorganisms. Microbes are key players in virtually all biological and environmental systems, yet limitations in current techniques used to study microbial metabolism make it difficult to decode their interactions and activities. The new research, published February 5, 2023 in Nature Microbiology, directly addresses these limitations, which could ultimately transform our understanding of both human health and the environment. “Humans are walking ecosystems in which microbes vastly ...

Pulmonary rehabilitation is difficult for millions of Americans to access

2024-02-05

New Haven, Conn. — Pulmonary rehabilitation, an essential component of care for patients with chronic respiratory conditions, is difficult for millions of Americans to access, a new Yale-led study reveals. The findings, researchers say, reveal geographic regions where this type of care is most lacking and illustrate the potential for telemedicine in helping to bridge this gap. The study was published Feb. 5 in JAMA Network Open. Pulmonary rehabilitation is a multidisciplinary program that incorporates exercise and strategic techniques to improve quality of life and overall health for patients with respiratory conditions like chronic ...

Bacterial test for raw, organic milk may require more precision

2024-02-05

ITHACA, N.Y. -- Cornell food scientists show that a standard quality test used for raw, organic milk is insufficient for distinguishing between specific groups of bacteria, suggesting that the criteria for determining milk quality at processing plants needs to be updated. Their work was published Jan. 20 in the Journal of Dairy Science. “Testing milk should not be one size fits all,” as tests should be used appropriately to give the best feedback to dairy producers, said lead author Renee Lee ’21, ...

Brazilian researcher helps describe a novel species of jellyfish discovered in a remote location in Japan

2024-02-05

A gelatinous animal with a diameter of about 10 cm and a red stomach resembling the Cross of St George when seen from above. This is Santjordia pagesi, a newly described species of medusa. Medusae are a type of free-swimming, umbrella-shaped jellyfish with a reduced stalk. The new species is described in an article published in the journal Zootaxa. The study was conducted by an international group of researchers that included a Brazilian scientist supported by FAPESP. The scientist in question is André Morandini, last author ...

Small but mighty – study highlights the abundance and importance of the ocean’s tiniest inhabitants

2024-02-05

Tiny plankton – measuring less than 20µm (or 0.02mm) in diameter – make up the majority of plankton in the ocean and play a critical role in the planet’s health, according to new research. However, scientists say challenges in identifying them have led to them becoming a silent majority that is currently being overlooked when it comes to global ocean policy. The study is one of the first to explore the abundance and importance of these tiny ocean inhabitants around the UK coastline, with the technology capable of monitoring them only having been introduced in around 2010. However, ...

Bullied teens’ brains show chemical change associated with psychosis

2024-02-05

Researchers have found that adolescents being bullied by their peers are at greater risk of the early stages of psychotic episodes and in turn experience lower levels of a key neurotransmitter in a part of the brain involved in regulating emotions. The finding suggests that this neurotransmitter — a chemical messenger that transmits nerve impulses for communication by a nerve cell — may be a potential target for pharmaceutical interventions aimed at reducing the risk of psychotic disorders. Psychosis is a mental state characterized by loss of contact with reality, incoherent speech and behavior, and typically hallucinations and delusions seen in psychiatric disorders ...

Unlocking precision medicine for inflammatory bowel disease

2024-02-05

The prevalence of inflammatory bowel disease (IBD), encompassing ulcerative colitis (UC) and Crohn's disease (CD), is rapidly increasing worldwide, affecting an estimated 6.8 million people. This surge brings significant economic burdens, with annual healthcare costs exceeding $12,000 and $7,000 for CD and UC patients, respectively. Tailored drug selection based on individual factors can potentially reduce these costs and improve patient outcomes. Factors associated with a Western lifestyle such as urbanization, high animal protein intake, ultra-processed foods, and reduced fiber ...
