Geriatric Assessment Reveals Actionable Impairments in Hematopoietic Stem Cell Transplant Candidates Ages 18-80 Years.

Transplant Cell Ther 2022 May 17. Epub 2022 May 17.

Division of Hematologic Malignancies and Cellular Therapy, Duke University Medical Center, Durham, NC.

Current state of unhealthy living characteristics in White, African American and Latinx populations.

Prog Cardiovasc Dis 2022 May 16. Epub 2022 May 16.

Healthy Living for Pandemic Event Protection (HL - PIVOT) Network, Chicago, IL, USA; Fisher Institute of Health and Well-Being, College of Health, Ball State University, Muncie, IN, USA.

The United States (US) is similar to most industrialized countries in that it falls short on many of the basic metrics related to cardiovascular and overall health. These metrics include nutritional patterns, levels of physical activity (PA), cardiorespiratory fitness (CRF), and prevalence of overweight and obesity. These issues are even more apparent in underserved communities, among whom unhealthy living characteristics cluster and contribute to a disproportionate chronic disease burden. Read More

Eviction, intimate partner violence and HIV: Expanding concepts and assessing the pathways through which sexual partnership dynamics impact health.

Soc Sci Med 2022 May 11;305:115030. Epub 2022 May 11.

American University, Department of Sociology, 4400 Massachusetts Avenue, Washington DC, 20016, USA. Electronic address:

Over 2 million renters in the United States are legally evicted annually, and even more renters experience other landlord-related forced moves each year. While past research has documented an association between legal eviction and HIV risk, no studies have examined the relationship between forced moves and sexual partnership dynamics longitudinally, or the pathways through which forced moves impact such risk. Addressing this gap is imperative, particularly given inequities that place Black renters and women at disproportionate risk of eviction. Read More

Screening of highly discriminative microhaplotype markers for individual identification and mixture deconvolution in East Asian populations.

Forensic Sci Int Genet 2022 May 15;59:102720. Epub 2022 May 15.

National Engineering Laboratory for Forensic Science, Key Laboratory of Forensic Genetics of Ministry of Public Security, Institute of Forensic Science, Ministry of Public Security, Beijing 100038, China. Electronic address:

Microhaplotypes are forensic genetic markers that combine single nucleotide polymorphisms in close proximity to one another. Highly discriminative microhaplotype markers could be superior to short tandem repeats (STRs) in DNA mixture deconvolution investigations because they are not interfered by stutters. In this study, the effective number of alleles (A) and discrimination power values of microhaplotypes and STRs were compared. Read More

Comparison of virus detection, productivity, and economic performance between lots of growing pigs vaccinated with two doses or one dose of PRRS MLV vaccine, under field conditions.

Prev Vet Med 2022 May 13;204:105669. Epub 2022 May 13.

Veterinary Diagnostic and Production Animal Medicine Department, College of Veterinary Medicine, Iowa State University, Ames, IA, USA. Electronic address:

Porcine reproductive and respiratory syndrome virus (PRRSV) causes a significant economic impact on swine production. It has been demonstrated that PRRS modified-live virus (MLV) vaccination of pigs, with one full dose, significantly reduces clinical consequences of wild-type PRRSV infection compared to non-vaccinates. However, there is limited information about the effect that two doses of PRRSV MLV vaccine have on the performance of growing pigs, compared to vaccination with a single dose. Read More

Environ Entomol 2022 May 20. Epub 2022 May 20.

Agriculture and Agri-Food Canada, Summerland Research and Development Centre, Summerland, BC, Canada.

Two species of larval parasitoids of the globally invasive fruit pest, Drosophila suzukii (Diptera: Drosophilidae), Leptopilina japonica, and Ganaspis brasiliensis (both Hymenoptera: Figitidae), were detected in British Columbia, Canada in 2016 and 2019, respectively. Both are presumed to have been unintentionally introduced from Asia; however, the extent of their establishment across different habitats with diverse host plants used by D. suzukii was unclear.

Educators' Views on the Use of Dissection and Dissection Alternatives in American Biology Classrooms.

Altern Lab Anim 2022 May 20:2611929221096578. Epub 2022 May 20.

The National Anti-Vivisection Society, Chicago, IL, USA.

Animal dissection remains a common practice in American biology classrooms, despite the availability of dissection alternatives to study anatomy and physiology. Indeed, there is a growing body of evidence in the literature suggesting that the use of alternatives leads to the greater achievement of learning objectives, as compared to dissection. To better understand the current use of and attitudes toward dissection and alternatives, a nationwide survey of (mainly high-school) biology teachers ( = 2687) was conducted. Read More

Impact of breakthrough COVID-19 cases during the Omicron wave on vascular health and cardiac autonomic function in young adults.

Am J Physiol Heart Circ Physiol 2022 May 20. Epub 2022 May 20.

Department of Kinesiology, The University of Texas at Arlington, Arlington, Texas, United States.

We and others have previously shown that COVID-19 results in vascular and autonomic impairments in young adults. However, the newest variant of COVID-19 (Omicron) appears to have less severe complications.

Assessment of Bias in Patient Safety Reporting Systems Categorized by Physician Gender, Race and Ethnicity, and Faculty Rank: A Qualitative Study.

JAMA Netw Open 2022 May 2;5(5):e2213234. Epub 2022 May 2.

Office of Faculty Development and Diversity, Stanford University School of Medicine, Palo Alto, California.

Importance: Patient safety reporting systems (PSRSs) are designed to decrease the risk of harm to patients due to medical errors. Owing to the voluntary nature of PSRSs, implicit bias of the reporter may affect the management of safety events reported. Stanford Alert For Events (SAFE) is the PSRS used at Stanford Health Care.

JAMA Netw Open 2022 May 2;5(5):e2213242. Epub 2022 May 2.

Friedman School of Nutrition Science and Policy, Tufts University, Boston, Massachusetts.

Importance: Little is known about the association of trimethylamine N-oxide (TMAO), a novel plasma metabolite derived from L-carnitine and phosphatidylcholine, and related metabolites (ie, choline, betaine, carnitine, and butyrobetaine) with risk of death among older adults in the general population.

Objective: To investigate the associations of serial measures of plasma TMAO and related metabolites with risk of total and cause-specific death (ie, deaths from cardiovascular diseases [CVDs] and non-CVDs) among older adults in the US.

Design, Setting, And Participants: This prospective cohort study involved 5333 participants from the Cardiovascular Health Study-a community-based longitudinal cohort of adults aged 65 years or older-who were followed up from June 1, 1989, to December 31, 2015. Read More

Jordi Merino

Diabetologia 2022 May 20. Epub 2022 May 20.

Diabetes Unit and Center for Genomic Medicine, Massachusetts General Hospital, Boston, MA, USA.

Diet plays a fundamental role in maintaining long-term health, with healthful diets being endorsed by current dietary guidelines for the prevention and management of type 2 diabetes. However, the response to dietary interventions varies widely, highlighting the need for refinement and personalisation beyond population-based 'one size fits all'. This article reviews the clinical evidence supporting precision nutrition as a fundamental approach for dietary advice in diabetes. Read More
