(Press-News.org) About The Study: In this study using data from three large prospective cohort studies among 123,000 individuals, low-carbohydrate diets that emphasized high-quality proteins, fats and carbohydrates from whole grains and other healthy plant-based foods were significantly associated with slower weight gain in the long term. In contrast, low-carbohydrate diets emphasizing animal-sourced proteins and fats or refined carbohydrates were associated with faster weight gain.

Benzodiazepine use during pregnancy and risk of miscarriage
2023-12-27
About The Study: This nationwide case-time-control study revealed an increased risk of miscarriage associated with benzodiazepine use during pregnancy after accounting for measurable confounders, and results were unlikely to be due to unmeasured confounding. These findings underscore the necessity for health care professionals to meticulously balance the risk-benefit ratio when considering the use of benzodiazepines to treat psychiatric and sleep disorders during pregnancy.

Comparison of capture rates of the National Cancer Database across race and ethnicity
2023-12-27
About The Study: In this study of individuals diagnosed with cancer in the National Cancer Database (NCDB), Hispanic and American Indian or Alaska Native individuals diagnosed with breast, colorectal, lung, and prostate cancer were undercaptured in the NCDB, but their representation improved over time. Increased study is needed to determine where these populations predominantly seek cancer care.

A study of the genetics of pericarditis increases understanding of newly approved drug treatment

A study of the genetics of pericarditis increases understanding of newly approved drug treatment
Sequence variants that protect against pericarditis have been discovered at a genomic locus encoding interleukin-1 immune cytokines. A newly approved drug treatment for pericarditis inhibits these cytokines and new a study from deCODE genetics and collaborators can contribute to the further development of this treatment.
A new study called “Variants at the interleukin-1 gene locus and pericarditis” was published today in the journal JAMA Cardiology, by scientists at deCODE genetics, a subsidiary of Amgen, and their collaborators from Denmark, USA, and Iceland.

New reptile on the block: A new iguana species discovered in China
2023-12-27
A new iguana joins Asia’s rich reptile fauna, officially described as new to science in the open-access journal ZooKeys.
“From 2009 to 2022, we conducted a series of field surveys in South China and collected a number of specimens of the Calotes versicolor species complex, and found that the population of what we thought was Calotes versicolor in South China and Northern Vietnam was a new undescribed species and two subspecies,” says Yong Huang, whose team described the new species.

Quality of care declines after private equity takes over hospitals
2023-12-26
At a glance:
National study of quality of care in hospitals acquired by private equity shows worsening of fall and infection risk, other measures of quality and safety.
Some post-procedure adverse events increased even though private equity hospitals performed fewer procedures among younger and less disadvantaged patients.
The new findings amplify existing economic concerns about the growth of this for-profit ownership model.
Patients are more likely to fall, get new infections, or experience other forms of harm during their stay in a hospital after it is acquired by a private equity firm, according to a new ...
Changes in hospital adverse events and patient outcomes associated with private equity acquisition
2023-12-26
About The Study: Private equity acquisition of hospitals, on average, was associated with increased hospital-acquired adverse events despite a likely lower-risk pool of admitted Medicare beneficiaries, suggesting poorer quality of inpatient care. These findings heighten concerns about the implications of private equity on health care delivery.

Variation by institution in sexual harassment experiences among medical interns
2023-12-26
About The Study: Among a national cohort of medical interns, over half experienced sexual harassment. Although harassment was prevalent across programs, institutional and specialty training variations in interns’ sexual harassment experiences exist, thereby providing additional evidence that residency programs and institutions play an important role in combating this widespread problem.

Negative wealth shock and cognitive decline and dementia in middle-aged and older adults
2023-12-26
About The Study: In this study of 8,000 participants, negative wealth shock (a loss of 75% or more in total wealth over a 2-year period) was associated with accelerated cognitive decline and elevated risks of dementia among middle-aged and older U.S. adults, with modifications by age and ethnicity. These findings should be confirmed by further prospective and interventional studies.

Prediction of 2-year cognitive outcomes in very preterm infants using machine learning methods
2023-12-26
About The Study: The findings of this prognostic study of cognitive outcomes at 2-year follow-up among 1,000 infants born very preterm suggest that predictive modeling in neonatal care could enable early and targeted intervention for very preterm infants most at risk for developing cognitive impairment.

Pet ownership, living alone, and cognitive decline among adults age 50 and older
2023-12-26
About The Study: Pet ownership was associated with slower rates of decline in verbal memory and verbal fluency among older adults living alone, but not among those living with others in this study of 7,900 participants age 50 and older. Pet ownership offset the associations between living alone and declining rates in verbal memory and verbal fluency. Further studies are needed to assess whether pet ownership slows the rate of cognitive decline in older adults living alone.
