Capsaicin, derived from hot chili pepper plants, has been used to treat various types of pain, and a high concentration capsaicin patch (HCCP) is approved for the treatment of nerve (or neuropathic) pain. In a real-world study published in Pain Practice that included 97 outpatients in Germany diagnosed primarily with neuropathic back pain, postoperative/posttraumatic neuropathic pain, or postherpetic neuralgia (shingles pain), patients appeared to benefit from multiple HCCP applications. Among the ...

An analysis of relevant published studies indicates that across all ages, food allergy negatively affects individuals’ quality of life to a greater extent in females than in males. The analysis, which is published in Clinical and Experimental Allergy, included 34 studies. In the studies, women and the parents of girls tended to report a greater impact of food allergy on health-related quality of life than men or parents of boys. Evidence also showed that improvements in quality of life over the course of treatment for food allergy can be different for males and females, with weak evidence suggesting that male children may experience more improvements ...

A recent analysis of data from nearly all World Health Organization member states clearly demonstrates a link between air pollution and mortality from cardiovascular diseases, with more of such deaths associated with air pollution in low-income countries compared with high-income countries. In all 183 countries included in the Chronic Diseases and Translational Medicine study, ischemic heart disease-related deaths attributed to air pollution were higher than stroke-related deaths caused by air pollution. In 2019, outdoor air pollution caused 16 ischemic heart disease-related deaths per 100,000 people in high-income countries compared with 70 per 100,000 in low-income countries. Also, in ...

Researchers are actively working on non-flammable solid electrolytes as a safer alternative to liquid electrolytes commonly found in lithium-ion batteries, which are vulnerable to fires and explosions. While sulfide-based solid electrolytes exhibit excellent ionic conductivity, their chemical instability with high-voltage cathode materials necessary for high-energy-density batteries has impeded their commercial viability. Consequently, there has been a growing interest in chloride-based solid electrolytes, which are stability in high-voltage conditions due to their strong bonding ...

COLUMBUS, Ohio – Keeping track of blood pressure, cholesterol and blood sugar levels can help identify risk factors for heart disease. However, a national survey by The Ohio State University Wexner Medical Center found that while many adults know their childhood address or best friend’s birthday, less than half know their blood pressure or ideal weight, and fewer than 1 in 5 know their cholesterol or blood sugar levels.    “Recognizing heart disease risk factors early and adequately treating ...

In patients with major depression disorder it is, thanks to use of artificial intelligence, now possible to predict within a week whether an antidepressant will work. With the help of an AI algorithm, a brain scan and an individual's clinical information, researchers from Amsterdam UMC and Radboudumc could see up to 8 weeks faster whether or not the medication would work. The results of this study are published today in the American Journal of Psychiatry. "This is important news for patients. Normally, ...

As a predator of soil microorganisms, nematodes respond rapidly to changes in soil environment, which can reflect climate conditions, ecosystem succession status, nutrient cycling and soil ecosystem health. In agroecosystems, nitrogen and phosphate fertilizers are often applied in large quantities. Therefore, studying the effect of nitrogen and phosphorus addition on soil nematode communities is helpful to understand how nitrogen and phosphorus addition affects the growth and development of crops in farmland ecosystems. This study demonstrates that the addition of nitrogen and phosphorus significantly ...

Hepatocellular carcinoma (HCC) is a common disease in human history and one of the main causes of cancer-related death. Sorafenib (SORA) is the best representative of angiogenesis inhibitors and is currently being commonly used in the treatment of advanced HCC as a first-line drug. Although SORA improves the overall survival rate of patients with liver cancer, acquired resistance to SORA has been found in patients with liver cancer and this has led to poor treatment outcomes. Hypoxia is one of the inducements of SORA resistance. Since ...

Women have a four times higher risk of dying from cardiovascular disease if they have an infection with a high-risk strain of the human papillomavirus (HPV), according to research published in the European Heart Journal [1] today (Wednesday).   HPV is a very common infection and high-risk strains are known to cause cervical cancer. Previous research has suggested that HPV may also contribute to the build-up of dangerous plaque in the arteries. However, this is the first study to show a link between high-risk HPV infection and deaths from cardiovascular disease.   The research was led by Professors ...

Daily exposure to chemicals used in the manufacture of plastic food containers and many cosmetics may be tied to nearly 56,600 preterm births in the U.S. in 2018, a new study shows. The resulting medical costs, the authors of the report say, were estimated to reach a minimum of $1.6 billion and as much as $8.1 billion over the lifetime of the children. For decades, the chemicals, called phthalates, have been shown to interfere with the function of certain hormones, or signaling compounds that circulate in the blood and guide much of the body’s processes. Exposure to these toxins, which is believed to occur as consumer products break down and are ingested, has been linked ...

Action is urgently needed to address the dearth of older women in sport and exercise science, not only for the sake of the growing numbers of female athletes, but women’s health in general, urge a group of international researchers in an editorial, published online in the British Journal of Sports Medicine. There are already far too few sports and exercise science studies that include women, point out the authors, citing their own 2021 report on the sex data gap.  This showed that out of 5261 studies, from across six popular sport and exercise science journals, women and girls made up just over a third of the total number of participants, a figure that is likely ...

Women may find it harder to emotionally adjust to divorce or a relationship break-up in later life than men do, if patterns of antidepressant use are indicative, suggests a large long term study published online in the Journal of Epidemiology & Community Health. While both sexes increased their antidepressant use in the run up to, and immediate aftermath of, a divorce, break-up, or bereavement, women’s use of these drugs was greater than men’s. And while re-partnering was associated with a slight reduction in antidepressant use in both sexes, it was particularly short-lived in women, the study findings indicate. Due to population ...

Clocking up high weekly levels of moderate to vigorous intensity physical activity is linked to a lower risk of developing chronic kidney disease in overweight/obese people with type 2 diabetes, finds research published online in the British Journal of Sports Medicine. But boosting the weekly tally by just over an hour is linked to a 33% reduction in risk, with the effects apparent for bouts lasting above or below 10 minutes at a time, the findings indicate. Diabetes is the leading cause of chronic kidney disease, accounting for 30–50% of all such cases. Diabetes plus chronic kidney disease is associated with a 10-fold or greater increase in the risk of death from any cause ...

New research led by Monterey Bay Aquarium and the University of California, Santa Cruz, reveals that denser, and more sheltered, kelp forests can withstand serious stressors amid warming ocean temperatures. Published in Proceedings of the Royal Society B, the study also offers the first comprehensive assessment of how declines in kelp abundance affected marine algae, invertebrates, and fishes living in Monterey Bay. The study comes after a multi-year marine heatwave – the product of a 2014 ‘blob’ ...

Fine motor skills in young children are linked to better GCSE scores and fewer behavioural problems in childhood and adolescence, according to a new study from the University of Surrey and Birkbeck, University of London. The authors suggest that preschool fine motor skills, including drawing, folding paper and block building, may play an important role in the pathway between infancy and later educational and behavioural outcomes in primary and secondary school.   The study showed that fine motor skills ...

In May 1953, Filipino ornithologist D. S. Rabor collected a single female fruit dove on the forested slopes of an active volcano on the Philippine island of Negros. The small apple green bird, which had yellow edgings on its wings and prominent circles of bare skin around its eyes,      was unlike any other known pigeon species. In 1954, Rabor and Yale professor Dillon Ripley described the unique specimen as Ptilinopus arcanus, a name inspired by the Latin word for “secret.” The Negros Fruit Dove, as it is commonly known, has never been ...

As interest in wearable technology has surged, research into creating energy-storage devices that can be woven into textiles has also increased. Researchers at North Carolina State University have now identified a “sweet spot” at which the length of a threadlike energy storage technology called a “yarn-shaped supercapacitor” (YSC) yields the highest and most efficient flow of energy per unit length. “When it comes to the length of the YSC, it’s a tradeoff between power and energy,” said Wei ...
