Geisinger researchers find sex is not an independent risk factor for stroke mortality
Stroke survival rates for men and women equal among Geisinger patients
2021-01-19
(Press-News.org) DANVILLE, Pa. - An analysis of data collected from patients treated for ischemic stroke at Geisinger shows no disparity in outcomes based solely on sex.
Various studies have suggested that women are disproportionately affected by stroke and may have poorer stroke outcomes. Women have a longer life expectancy than men and, therefore, likely have an increased lifetime risk of stroke. Women tend to be older than men at the time of stroke and have a higher pre-stroke degree of disability or dependence in their daily activities, which may contribute to worse outcomes. Rural populations may also have a higher risk of stroke based on a greater incidence of conditions like hypertension and poorly controlled diabetes.
Researchers at Geisinger analyzed electronic health record data for 8,900 patients who had an ischemic stroke between 2004 and 2019. Overall, female patients had a higher rate of all-cause mortality following stroke. However, after controlling for comorbidities, such as atrial fibrillation, diabetes, heart failure, and chronic lung or kidney diseases, survival rates for men and women were equal.
"Our study results indicate that women may have higher crude mortality after stroke; however, sex is not an independent risk factor for all-cause mortality in the rural communities that Geisinger serves," said Vida Abedi, Ph.D., a scientist in the department of molecular and functional genomics at Geisinger and a co-author of the study. "Ischemic stroke recurrence and the composite outcome of stroke recurrence or death also did not demonstrate evidence of a sex disparity."
The results were published in Therapeutic Advances in Neurological Disorders.
INFORMATION:
The study is part of a larger effort by the Neuroscience Institute at Geisinger, led by Ramin Zand, M.D., a vascular neurologist and president of the American Heart Association (AHA) Northeast Pennsylvania, with a focus on addressing stroke care disparity and women's health, one of the current missions of AHA. The data analysis was led by Clare Lambert, a student at Geisinger Commonwealth School of Medicine.

People with anxiety and depression are more likely to report an increase in drinking during the COVID-19 pandemic than those without mental health issues, according to a new study by researchers at NYU School of Global Public Health published in the journal Preventive Medicine. While drinking grew the most among younger people, older adults with anxiety and depression saw a sharper increase in their risk for harmful alcohol use.
"This increase in drinking, particularly among people with anxiety and depression, is consistent with concerns that the pandemic may be triggering an epidemic of problematic ...

Genetic rewiring could have driven an evolutionary explosion in the shapes, sizes and adaptations of cichlid fish, in East Africa's answer to Darwin's Galapagos finches.
Published in BMC Genome Biology, an Earlham Institute (EI) study, with collaborators at the University of East Anglia (UEA) and Wisconsin Institute for Discovery, shows that 'genetic rewiring' at non-coding regions - rather than mutations to protein-coding regions of genes - may play an important role in how cichlid fish are able to rapidly adapt to fill a staggeringly wide range of environmental niches in the East African Rift lakes.
The results ...

ATLANTA - JANUARY 19, 2021 - A new study finds that alcohol consumption accounts for a considerable portion of cancer incidence and mortality in all 50 states and the District of Columbia. The article, which appears in Cancer Epidemiology, states that the proportion of cancer cases attributable to alcohol consumption ranged from a high of 6.7% in Delaware to a low of 2.9% in Utah. Similarly, Delaware had the highest proportion of alcohol-related cancer deaths (4.5%) and Utah had the lowest (1.9%).
This study conducted by Farhad Islami, MD, PhD, and colleagues at the American Cancer Society is the first to estimate contemporary proportions and counts of alcohol-attributable ...

Psoriasis is a chronic inflammatory skin disease characterized by erythematous (red) patches and plaques. In some patients, psoriasis may be associated with comorbidities such as arthritis, obesity, diabetes, cardiovascular diseases, hyperlipidemia, or depression. Psoriasis lesions can occur on the scalp and face, in addition to all other areas of the body, causing considerable physical discomfort and psychosocial trauma from the stigma surrounding appearance defects.
More than 90% of patients with psoriasis have what is called psoriasis vulgaris, which is characterized ...

Researchers in the UK and the United States have succeeded in 'fine tuning' a new thermoplastic biomaterial to enable both the rate at which it degrades in the body and its mechanical properties to be controlled independently.
The material, a type of polyester, has been designed for use in soft tissue repair or flexible bioelectronics by a team at the University of Birmingham in the UK and Duke University in the US.
Materials that successfully replicate the necessary elasticity and strength of biological tissues but which also biodegrade over an appropriate timescale are extremely ...

DANVILLE, Pa. - A team of Geisinger researchers has identified a common genetic variant as a risk factor for stroke, especially in patients older than 65.
Cerebral small vessel disease (SVD) causes about a quarter of ischemic strokes worldwide and is the most common cause of vascular dementia. SVD can manifest as lesions on the brain, which typically appear on brain scan images. SVD is commonly associated with aging and hypertension, but a minority of cases are caused by cysteine altering variants in the NOTCH3 gene. Approximately 1 in 300 people have this type of gene variant. A rare hereditary condition known as cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy, or CADASIL, which is caused by this gene variant, has been associated with ...

Consumers of purchased foods have no way of ascertaining the quality and safety of the food that existing distribution systems deliver to their plates. Unfortunately, inappropriate refrigeration can sometimes lead to food spoilage, which is often difficult to detect. Such is the case for mackerel fish, which readily develop harmful levels of a substance called histamine when left at room temperature for too long. Histamine is neurotoxic and can trigger severe allergic reactions, including rashes, vomiting, and diarrhea. Because spoiled fish can sometimes look and smell completely normal, it is important to accurately quantify ...

Scientists are searching for lithium technology alternatives in the face of the surging demand for lithium-ion batteries and limited lithium reserves. Russian researchers from Skoltech, D. Mendeleev University, and the Institute of Problems of Chemical Physics of RAS have synthesized and tested new polymer-based cathode materials for lithium dual-ion batteries. The tests showed that the new cathodes withstand up to 25,000 operating cycles and charge in a matter of seconds, thus outperforming lithium-ion batteries. The cathodes can also be used to produce less expensive potassium ...

Having a choice of foods may accelerate aging and shorten the lifespan of fruit flies, according to a study published today in the open-access eLife journal.
While early experiments have shown that calorie restriction can extend lifespan, the current study adds to the growing body of evidence that suggests other diet characteristics besides calories may also influence aging and lead to earlier death.
"It has been recognised for nearly a century that diet modulates aging," says first author Yang Lyu, Postdoctoral Fellow at the Department of Molecular & Integrative Physiology, University of Michigan Medical School, Ann Arbor, US. "For our study, we wanted to see if having a choice of foods affects metabolism and lifespan in the fruit fly Drosophila melanogaster."
