News at a glance: A win for obesity drugs, NIH unionization roadblocks, and Mexican fireflies under threat
CONSERVATION Researchers raise alarm over threat to Mexican fireflies Scientists from the International Union for Conservation of Nature (IUCN) last week delivered a letter to the Mexican government requesting it regulate tourism centered on the threatened firefly species Photinus palaciosi . Endemic to Mexico’s Tlaxcala forests, P. palaciosi is one of the few species that glow in synchrony, offering an annual spectacle that attracts thousands of visitors during summer mating season. The letter describes how littering, artificial light, and noise interfere with the insects’ courtship and eg...

Where You Live Can Shape How Alzheimer ’ s Affects You
The FDA in mid-July for the first time ever approved an Alzheimer’s drug, Leqembi. The annual price-tag will run patients $26,500. The same week, the Alzheimer’s Association for the first time ever released county-level data to identify which communities are most struggling with the disease. 6.7 million Americans live with Alzheimer’s disease and 134,000 of them will die because of it each year. We’ve known these aggregate numbers for a while now, but with new data and new drugs, healthcare specialists can now better target attention and resources. [time-brightcove not-tgx=”true”] ...

When does life end? New organ donation strategy fuels debate
On a chilly holiday Monday in January 2020, a medical milestone passed largely unnoticed. In a New York City operating room, surgeons gently removed the heart from a 43-year-old man who had died and shuttled it steps away to a patient in desperate need of a new one. More than 3500 people in the United States receive a new heart each year. But this case was different—the first of its kind in the country. “It took us 6 months to prepare,” says Nader Moazami, surgical head of heart transplantation at New York University (NYU) Langone Health, where the operation took place. The run-up included oversight from an ethi...

White matter microstructure and verbal fluency
We examined white matter correlates of semantic (Category Fluency Animals) and phonemic or lexical fluency (COWAT FAS) after stroke, accounting for stroke severity measured with the National Institutes of health Stroke Scale (NIHSS), age, sex, and level of education. White matter fibre density and cross-section measures were automatically extracted from 72 tracts, using MRtrix and TractSeg software in 72 ischaemic stroke survivors assessed 3 months after their event. We conducted regression analyses separately for phonemic and semantic fluency for each tract. Worse semantic fluency was associated with lower fibre density i...

Association of cognitive reserve with stroke outcome: a protocol for a systematic review
Introduction The concept of cognitive reserve (CR) was introduced to account for individual differences in the clinical manifestation of neurodegenerative diseases. Though several mechanisms and risk factors are shared between neurodegeneration and stroke, the effect of CR on poststroke functional outcome has been poorly addressed. This systematic review aims to synthesise the available research evidence on the association of CR with stroke outcome, in order to implement the understanding of interindividual variability in stroke outcome and to improve its prediction. Methods and analysis Cochrane Library, Embase, PubMed, ...

What the Science Says About the Health Benefits of Vitamins and Supplements
From multivitamins and melatonin to fiber and fish oil, Americans who are trying to boost their health and immunity have a plethora of supplements to choose from. An estimated 58% of U.S. adults ages 20 and over take dietary supplements, according to the U.S. Centers for Disease Control and Prevention, and the supplement industry is valued at more than $30 billion a year. Supplement use has been growing rapidly over the past few decades along with the wellness industry. “The popular belief is that a supplement is going to be helpful for promoting health,” says Fang Fang Zhang, a professor at Tufts University&rs...

A Prospective Stroke Register in Sierra Leone: Demographics, Stroke Type, Stroke Care and Hospital Outcomes
This study reports the demographics, stroke types, stroke care and hospital outcomes for stroke in Freetown, Sierra Leone.Methods: A prospective observational register recorded all patients 18 years and over with stroke between May 2019 and April 2020. Stroke was defined according to the WHO criteria. Pearson's chi-squared test was used to examine associations between categorical variables and unpaired t-tests for continuous variables. Multivariable logistic regression, to explain in-hospital death, was reported as odds ratios (ORs) and 95% confidence intervals.Results: Three hundred eighty-five strokes were registered, an...

The Impact of Vascular Risk Factors on Post-stroke Cognitive Impairment: The Nor-COAST Study
Discussion: Our findings indicate that a focal stroke lesion might be related to pathophysiological processes leading to global cognitive impairment. The poorer prognosis of PSCI in patients with vascular risk factors emphasizes the need for further research on complex vascular risk factor interventions to prevent PSCI.

Neuropsychological and neuroimaging assessments of early cognitive impairment in patients after mild ischemic stroke and transient ischemic attack.
This study aimed to identify markers of early cognitive impairment after acute mild ischemic cerebrovascular disease. To further explore the relationship between neuroimaging markers of vascular and neurodegenerative injuries and post-stroke cognitive impairment, 86 patients with transient ischemic attack/acute mild ischemic stroke were recruited. Demographic information, clinical data, stroke scale scores (Modified Rankin Scale, National Institutes of Health Stroke Scale), and neuroimaging parameters (medial temporal lobe atrophy, global cortical atrophy, white matter hyperintensities, location and number of acute infarct...
