About The Study: This single-center cohort study identified substantial overall survival disparity and differing frequencies of driver gene variations by race and ethnicity. Socioeconomic status had the largest contribution but accounted for less than one-third of the disparity, with substantial contribution from tumor molecular features. Further study of the associations of genetic ancestry and the molecular pathogenesis of colorectal cancer with chemotherapy response is needed.

About The Study: This study found that certain social determinants of health affected monitoring for diabetic retinopathy similarly for Black and white patients with diabetes while others affected them differently. Patients living in rural communities, Black patients with preexisting diabetic retinopathy, and Hispanic white patients were not receiving eye care in accordance with clinical practice guidelines, which may contribute to worse outcomes.

About The Study: In this cross-sectional study of neighborhood opportunity and preterm birth, elevated risk associated with exposure to a very low opportunity neighborhood, coupled with the disproportionate exposure by race and ethnicity, points to a modifiable factor that may contribute to racial and ethnic inequities in preterm birth. Future research should investigate interventions that seek to address neighborhood opportunity.

About The Study: In 2023, all 3 payer markets (commercial insurance, Medicare Part D, and Medicaid managed care) for pharmacy benefit manager (PBM) services were highly concentrated, but concentration varied and was highest in Medicare Part D. While CVS Caremark held the dominant share in all 3 payer markets, each of the PBMs appeared focused on a different payer: Express Script’s largest share was in the commercial market, while Optum Rx’s and CVS Caremark’s were in Medicare Part D and Medicaid managed care, respectively. These findings underscore the importance of considering payer-specific concentration when evaluating PBMs’ anticompetitive practices, as the 3 top PBMs may be pursuing different market strategies.

About The Study: In this study, parents who demonstrated and practiced proper firearm handling with their children and taught them how to shoot their firearms were more likely to store at least 1 firearm unlocked and loaded. Consistent with qualitative research results, these findings suggest that some parents may believe that modeling responsible firearm use negates the need for secure storage. However, it is unknown whether parents’ modeling responsible behavior is associated with a decreased risk of firearm injury.

About The Study: The findings of this cohort study showed a significant recent downward trend in both melanoma incidence and melanoma mortality in the age group 30 to 49 years in Sweden. The reasons for these declines are unclear but may include UV protection, public health campaigns, changing population demographics, and the introduction of effective melanoma treatment. None of these possibilities were evaluated; further study is needed.

About The Study: This is the first report of whole eye transplant combined with facial transplant, demonstrating allograft survival including rejection-free graft survival and electroretinographic measurements indicating retinal response to light stimuli. These data highlight the potential for clinical allotransplantation for globe loss. The successful revascularization of the transplanted eye achieved in this study may serve as a step towards the goal of globe transplant for restoration of vision.

 

Quote from corresponding author Eduardo D. Rodriguez, MD, DDS:

“The study reveals clinical outcomes from the past year following the world’s first whole-eye and partial-face transplant, highlighting promising initial results, and establishing a foundation for future advancements.

“While the recipient has not regained vision, the transplanted eye has maintained normal pressure, good blood flow, and some remaining structure and functions in the retina. Many experts did not think we would even be here, but we’ve successfully transplanted and maintained an eye without immune rejection.

“Now, the next challenge is understanding how to restore sight. I look forward to continuing this research in collaboration across academia to accelerate these discoveries with unique tools and the best therapies.”

About The Study: In patients with symptomatic intracranial atherosclerotic stenosis, balloon angioplasty plus aggressive medical management, compared with aggressive medical management alone, statistically significantly lowered the risk of a composite outcome of any stroke or death within 30 days or an ischemic stroke or revascularization of the qualifying artery after 30 days through 12 months. The findings suggest that balloon angioplasty plus aggressive medical management may be an effective treatment for symptomatic intracranial atherosclerotic stenosis, although the risk of stroke or death within 30 days of balloon angioplasty should be considered in clinical practice.

About The Study: At the lesion level, very intensive lipid-lowering therapy induced substantially greater percent atheroma volume regression than described in previous vessel-level analyses. Compared with statin therapy alone, alirocumab treatment was associated with greater enlargement of the lesion minimum lumen area and more frequent transition of presumably high-risk plaque phenotypes into more stable, less lipid-rich plaque phenotypes.

About The Study: Among adults age 60 years and older in 19 U.S. states, respiratory syncytial virus (RSV) vaccination was associated with a reduced likelihood of hospitalization with RSV compared with no vaccination. These findings expand upon prelicensure trial results in 2 ways. First, they provide evidence of vaccine protection against RSV-associated hospitalization, of which an estimated 60,000 to 160,000 occur annually among U.S. adults age 65 years and older. Second, they demonstrate protection in a population that more closely represents those at high risk of severe RSV disease, including adults age 75 years and older and those with immunocompromising conditions.

About The Study: In this study, women with hepatocellular carcinoma were less likely to receive a deceased-donor liver transplant and more likely to die while wait-listed than men with hepatocellular carcinoma; these differences were largely (but not entirely) explained by sex-based differences in candidate size. For candidates listed with exception scores, additional changes to allocation policy are needed to resolve the sex disparity, including solutions to improve access to size-matched donor livers for smaller candidates.

About The Study: The results of this post hoc analysis suggest that treatment with semaglutide, 2.4 mg, did not increase the risk of developing symptoms of depression or suicidal ideation/behavior vs placebo and was associated with a small but statistically significant reduction in depressive symptoms (not considered clinically meaningful). People with obesity should be monitored for mental health concerns so they can receive appropriate support and care.

About The Study: In this post hoc pooled analysis of 13,194 patients with chronic heart failure (HF) in the PARADIGM-HF and PARAGON-HF randomized clinical trials, sacubitril/valsartan significantly reduced hospitalization for any reason, with benefits most apparent in patients with a left ventricular ejection fraction below normal. This reduction appeared to be principally driven by lower rates of cardiac and pulmonary hospitalizations.

About The Study: In patients with ST-segment elevation myocardial infarction, treatment with prehospital pulse-dose glucocorticoid did not reduce final infarct size after 3 months. However, the trial was likely underpowered as the final infarct size was smaller than anticipated. The glucocorticoid group had improved acute parameters compared with placebo.

About The Study: For atrial fibrillation after cardiac surgery prophylaxis, supplementation only when serum potassium concentration fell below 3.6 mEq/L was noninferior to the current widespread practice of supplementing potassium to maintain a serum potassium concentration greater than or equal to 4.5 mEq/L. The lower threshold of supplementation was not associated with any increase in dysrhythmias or adverse clinical outcomes.

About The Study: Inhaler prescriptions filled by Centers for Medicare & Medicaid Services beneficiaries in 2022 resulted in an estimated 1.15 million metric tons of carbon dioxide equivalent emissions, equivalent to 226,960 homes’ yearly electricity use. Metered-dose inhalers were responsible for nearly all inhaler-related emissions, with the largest contribution arising from short-acting β-agonist medications. Although dry-powder and soft-mist inhalers had substantially lower emissions, they accounted for a disproportionate amount of spending, representing nearly two-thirds of inhaler costs but only one-third of claims.

About The Study: Postmenopausal women with historical hormone therapy (HT) use were biologically younger than those not receiving HT, with a more evident association observed in those with low socioeconomic status. The biological aging discrepancy mediated the association between HT and decreased mortality. Promoting HT in postmenopausal women could be important for healthy aging.

About The Study: In this cross-sectional cohort study of 170 former football players and 54 unexposed controls, larger perivascular space (PVS) volume was associated with greater exposure to repetitive head impacts (RHI). Additionally, PVS volume was associated with worse performance on cognitive tests. These findings suggest that PVS volume may contribute to the association between exposure to RHI, cognitive impairment, and the development of RHI-associated neurodegeneration.

About The Study: Researchers found corresponding increases in hypertension prevalence as neighborhood disadvantage and the percentage of Black patients residing in a neighborhood increased in this cross-sectional study. A higher burden of midlife hypertension was identified in Black adults compared with other racial and ethnic groups that persisted across levels of socioeconomic disadvantage. This study also found that living in socioeconomically disadvantaged neighborhoods was associated with higher hypertension rates among people of all racial and ethnic backgrounds. Using spatial analysis techniques to identify neighborhoods in need, future research might investigate structural interventions to address place-based hypertension disparities.

Trends of Heat-Related Deaths in the US, 1999-2023

About The Study: This study found that heat-related mortality rates in the U.S. increased between 1999 and 2023, especially during the last 7 years. Although a study using data through 2018 found a downward trend in heat-related mortality in the U.S., this study is the first to our knowledge to demonstrate a reversal of this trend from 2016 to 2023. These results align with site-specific data analyzed in a global study that suggest increases in heat-related mortality. As temperatures continue to rise because of climate change, the recent increasing trend is likely to continue. Local authorities in high-risk areas should consider investing in the expansion of access to hydration centers and public cooling centers or other buildings with air conditioning.
