Adjuvant therapies to help infertile women conceive by IVF - especially those whose treatments have been unsuccessful in the past - are now a common feature both before and during the treatment cycle. Now, a new analysis of the evidence for many nutritional supplements and diets thought to improve outcome in IVF has concluded that adopting a Mediterranean diet during treatment would offer a single ‘straightforward approach’ with good evidence of benefit in contrast to that of a Western diet. Evidence from studies of nine commonly used nutritional supplements was found to be inconsistent and not always of good quality. The analysis, by Professor Roger ...

A review in the Journal of Internal Medicine explores the potential of non-invasive interventions such as light, sound, and magnets to stimulate gamma brain waves for the treatment of Alzheimer’s disease. Such strategies may be beneficial because Alzheimer’s disease is characterized by reduced fast brain oscillations in the gamma range (30–100 Hz). The authors note that recent studies reveal that it is feasible and safe to induce 40 Hz brain activity in patients with Alzheimer’s disease through a range of methods. Also, preliminary evidence suggests that such treatment can yield beneficial ...

The inability to burp—called retrograde cricopharyngeus dysfunction (R-CPD)—is caused by failure of the throat’s cricopharyngeal muscle to relax to allow the outward passage of gas. An interview-based study in Neurogastroenterology & Motility that included 199 adults affected by the condition reveals the impact of R-CPD on quality of life. Most participants reported abdominal bloating, socially awkward gurgling noises, excessive flatulence, and difficulty vomiting. Only half discussed their symptoms with their primary care clinician, and 90% felt they did not receive ...

Women who lost a parent early in life may be more likely to experience separation anxiety with romantic partners during adulthood, according to a study published in Stress and Health. In addition to feeling distressed when separated from their partners, these women may also experience anxious attachment, or worry that significant others will not be available at times of need. The study included 60 women who lost one or both parents in their youth and 60 who had living parents. Based on participants’ answers to questionnaires, women who lost a parent reported higher levels of anxious attachment and adult separation anxiety ...

New research indicates that higher doses of topical corticosteroids, which are commonly used to treat inflammatory skin conditions, are linked with elevated risks of osteoporosis and bone fractures associated with osteoporosis. The findings are published in the Journal of the European Academy of Dermatology and Venereology and are based on information from the Taiwan National Health Insurance Research Database. Investigators selected 129,682 osteoporosis cases and 34,999 major osteoporotic fracture (MOF) cases and matched them with 518,728 and 139,996 controls (without osteoporosis or MOF) ...

Researchers have developed an augmented reality head-up display that could improve road safety by displaying potential hazards as high-resolution three-dimensional holograms directly in a driver’s field of vision in real time. Current head-up display systems are limited to two-dimensional projections onto the windscreen of a vehicle, but researchers from the Universities of Cambridge, Oxford and University College London (UCL) developed a system using 3D laser scanner and LiDAR data to create a fully 3D representation of London streets. The system ...

If we don’t take out the trash regularly, our homes become unpleasant and even a danger to our health. The same applies to our cells: If excess proteins and strands of genetic material aren’t removed, the cell and ultimately the entire organism can fall ill. For instance, scientists suspect there is a connection between Alzheimer’s and mutations that cause defects in cellular garbage removal. What’s more, tests with mice have shown that suppressing the breakdown of DNA and RNA can trigger serious autoimmune diseases. But concrete evidence is missing: “There’s a lot of research showing how genetic information in the ...

High-frequency terahertz waves have great potential for a number of applications including next-generation medical imaging and communication. Researchers at Linköping University, Sweden, have shown, in a study published in the journal Advanced Science, that the transmission of terahertz light through an aerogel made of cellulose and a conducting polymer can be tuned. This is an important step to unlock more applications for terahertz waves. The terahertz range covers wavelengths that lie between microwaves and infrared light on the electromagnetic spectrum. It has a very high frequency. Thanks to this, many researchers ...

Worldwide, more than one billion people are obese. Obesity is a risk factor for cardiovascular disease, diabetes, and some cancers. But permanently losing weight isn’t easy: complex interactions between body systems such as gut physiology, hormones, and the brain are known to work against it. One method for weight loss is intermittent energy restriction (IER), where days of relative fasting alternate with days of eating normally. “Here we show that an IER diet changes the human brain-gut-microbiome axis. The ...

Recent controversy has surrounded the concept of loot boxes – the purchasable video game features that offer randomised rewards but are not governed by gambling laws.   Now research led by the University of Plymouth has shown that at-risk individuals, such as those with known gaming and gambling problems, are more likely to engage with loot boxes than those without. The study is one of the largest, most complex and robustly designed surveys yet conducted on loot boxes, and has prompted experts to reiterate the call for stricter enforcement around them. ...

New research into large language models shows that they repeat conspiracy theories, harmful stereotypes, and other forms of misinformation.  In a recent study, researchers at the University of Waterloo systematically tested an early version of ChatGPT’s understanding of statements in six categories: facts, conspiracies, controversies, misconceptions, stereotypes, and fiction. This was part of Waterloo researchers’ efforts to investigate human-technology interactions and explore how to mitigate risks. They discovered that GPT-3 frequently made mistakes, contradicted ...

Researchers at Nagoya University in Japan have used artificial intelligence to discover a new method for understanding small defects called dislocations in polycrystalline materials, materials widely used in information equipment, solar cells, and electronic devices, that can reduce the efficiency of such devices. The findings were published in the journal Advanced Materials.    Almost every device that we use in our modern lives has a polycrystal component. From your smartphone to your computer to the metals and ceramics in your car. Despite this, polycrystalline materials are tough to utilize because of their complex structures. Along with their composition, the performance ...

A 12-week course of daily beetroot juice supplement for people with chronic obstructive pulmonary disease (COPD) lowered blood pressure and improved how far patients could walk in six minutes in research published today (Wednesday) in the European Respiratory Journal [1]. COPD is a serious lung condition affecting around 400 million people worldwide [2]. COPD which includes chronic bronchitis and emphysema, causes breathing difficulties and severely limits people’s capacity for physical activity. It also increases the risk ...

Blood fat-lowering statins could slow the progression of Alzheimer's disease, at least for some patients. This is the result of a new study led by Karolinska Institutet published in Alzheimer Research and Therapy. But the researchers are cautious in their interpretations and see the results as a first step in a research journey that may eventually provide the answer. A new study shows that people with Alzheimer's dementia deteriorated more slowly in their cognitive functions if they were also treated with a lipid-lowering ...

The use of potentially harmful ‘trip-killers’ to cut short ‘bad drug trips’ after taking psychedelics, such as LSD or magic mushrooms, is an emerging concern, warn doctors in a research letter, published online in Emergency Medicine Journal. Their analysis of relevant threads on the social media platform Reddit, shows that drugs such as benzodiazepines (sedatives) and antipsychotics are the options most frequently recommended, but warnings about their potential side effects are rarely included, they highlight. The intensity of a psychedelic drug trip can cause distress, agitation, ...

There are three potentially unique acoustic features of healing music that transcend musical genres, suggests research published in the open access journal General Psychiatry. The findings might help to personalise playlists for patients, using artificial intelligence to analyse individual physiological and psychological responses, and help to evaluate the effectiveness of existing music therapies, suggest the researchers. Despite evidence of the therapeutic effects of music for mental health issues, such as anxiety, depression, and post traumatic stress disorder, there’s no consensus on what defines healing ...

The diabetes drug dulaglutide (Trulicity) may significantly lower a woman’s risk of substantial weight gain after she has given up smoking, finds a secondary analysis of clinical trial data, published in the open access journal BMJ Nutrition Prevention & Health. Women seem to be 5 times as likely as men to put on a lot of weight after they’ve stubbed out what they intend to be their last cigarette, the analysis suggests. Women seem to have higher smoking relapse rates than men. And it’s been suggested that one of the possible explanations for this is that they may be more concerned about ...

SEATTLE, Wash., Dec. 19, 2023 ‑‑­­ Over 1.05 million deaths were associated with antimicrobial resistance (AMR) and 250,000 deaths were attributable to AMR in the WHO African region, posing an unprecedented health threat. That’s according to a new study published in The Lancet Global Health today.  The number of deaths linked to AMR in the WHO African region is higher than those caused by both HIV/AIDS (639,554) and malaria (594,348), marking a pivotal shift in the health challenges facing the region. Despite the relatively low prevalence of resistance, the WHO African region had the highest burden of AMR mortality, which ...

Groundbreaking new research from the Museums Victoria Research Institute has turned upside down our previous understanding of the evolution of the largest animals ever––baleen whales.  Palaeontologists Dr James Rule (Monash University and Natural History Museum, London) and Dr Erich Fitzgerald (Museums Victoria Research Institute) have co-authored the open access paper ‘Giant baleen whales emerged from a cold southern cradle’, published today in the prestigious journal Proceedings of the Royal Society B.   Until now, it was believed that the beginning of the Ice Age in the ...

A major report for the United Nations has put forward solutions to halve nitrogen pollution from agriculture and the food system in Europe, including reducing meat and dairy consumption, fertiliser use and food waste. Nitrogen, which is vital for plant growth, is present in animal excreta and synthetic fertilisers that are applied to land to boost crop production. But excessive and inefficient use of this nutrient means up to 80% of it leaks into the environment, mostly in various polluting forms of nitrogen: ammonia and nitrogen oxides, which are harmful air pollutants; ...

The numbers are stark and deeply troubling. Endometrial cancer — which develops in the lining of the uterus (womb) and is sometimes called uterine cancer — is on the rise in the U.S. In 1987, there were 35,000 cases annually. That number has nearly doubled in 2023 to more than 66,000 cases. Deaths from the disease have also grown alarmingly in the same period, from less than 3,000 to more than 13,000 in the U.S. every year. And the trend line is not getting better. “Endometrial cancer has been increasing at unprecedented levels over the past five years,” ...
