Experts: Impact of Covid-19 in Africa “vastly underestimated”

The impact of Covid-19 in Africa has been vastly underestimated, warn researchers in a new study. Outside of South Africa, this is the first study to provide systematic surveillance data capturing the impact of Covid-19 in Africa. Their findings are based on polymerase chain reaction (PCR) test results for 364 deceased people of all ages at the University Teaching Hospital morgue in Lusaka,…

Clinical trials during the pandemic: lessons for future cancer research

The continuing corona virus epidemic has impacted strongly on cancer care and research, including the delay of treatments and diagnoses as well as on trials of new therapies, and the shift in research to develop a Covid-19 vaccine. However, the session ‘Cancer research and Covid-19’, during the National Cancer Research Institute (NCRI) Virtual Showcase (online 2-3 November) looked at how UK…

Landmark study examines 'Covid effect' on cardiac surgery

The most deadly global health crisis in a century has resulted in a substantial decline in overall heart surgery volume and an unexplained increase in deaths after coronary artery bypass grafting, according to late-breaking research presented at the 57th Annual Meeting of The Society of Thoracic Surgeons.

Rapid blood test identifies Covid-19 patients at high risk of severe disease

One of the most vexing aspects of the Covid-19 pandemic is doctors’ inability to predict which newly hospitalized patients will go on to develop severe disease, including complications that require the insertion of a breathing tube, kidney dialysis or other intensive care. Knowledge of a patient’s age and underlying medical conditions can help predict such outcomes, but there are still…

'Prehabilitation' to aid recovery after surgery for older patients

Older adults about to undergo elective surgery should undertake a sustained programme of targeted exercise beforehand to counteract the muscle-wasting effects of bedrest, new research suggests. A study published by researchers in the University of Birmingham’s School of Sport, Exercise and Rehabilitation Sciences showed that short term ‘prehabilitation’ strength exercises, undertaken…

Gut microbiota plays a role in the development of Alzheimer

Alzheimer's disease is the most common cause of dementia. Still incurable, it directly affects nearly one million people in Europe, and indirectly millions of family members as well as society as a whole. In recent years, the scientific community has suspected that the gut microbiota plays a role in the development of the disease.

Will COVID-19 vaccines save lives? Right now, we cannot tell

Vaccines are being hailed as the solution to the COVID-19 pandemic, but the vaccine trials currently underway are not designed to tell us if they will save lives, reports Peter Doshi, Associate Editor at The BMJ. Several COVID-19 vaccine trials are now in their most advanced (phase 3) stage, but what will it mean exactly when a vaccine is declared “effective”? Many may assume that successful…

Creating 'COVID-19 free' hospital areas to save lives after surgery

Setting up ‘COVID-19 free’ hospital areas for surgical patients could save lives during the second wave of the pandemic – reducing the risk of death from lung infections associated with coronavirus, a new global study reveals. Researchers working together in Brazil and beyond found that that patients who had their operation and hospital care in ‘COVID-19 free’ areas had better outcomes.…

News • 'Rush to publish'

Have research standards suffered during COVID-19?

The COVID-19 pandemic has created a flood of potentially substandard research amid the rush to publish, with a string of papers retracted or under a cloud and a surge in submissions to pre-print servers where fewer quality checks are made, a leading ethicist has warned in the Journal of Medical Ethics. This has implications for patients, clinicians, and potentially government policy, says…

News • Study establishes link

Growth factor IGF-1 increases risk for several cancers

A study of almost 400,000 British participants has identified a new link between raised levels of the growth factor IGF-1 and increased thyroid cancer risk and has confirmed associations with breast, prostate and colorectal cancer. This could lead to new preventative strategies, including diet and lifestyle interventions.

Cholesterol drug combination could benefit heart patients

A new study has suggested that more patients could benefit from combinations of cholesterol-lowering drugs to reduce their risk of stroke and heart attacks. While risk is reduced for many patients through taking statins, those at the highest risk of cardiovascular events may benefit from combinations of lipid-lowering therapies, according to the results of a European study of patients across 18…

Why heart failure research needs more female authors

While about a quarter of physicians and researchers working in advanced heart failure (HF) and transplant cardiology are women, representation of women leading HF research remains limited, according to new research led by Penn Medicine. The authors say the findings point to a need to support great gender diversity among researchers to drive diversity among clinical trial participants and even…

Sterilisation study puts cleansing methods to the test

A new study from the USA highlights how low temperature sterilisation can jeopardise effective cleansing of medical tools and lead to transmission of dangerous bacteria to patients. Steam sterilisation was shown to be the most effective and robust sterilisation technology. However, the researchers, working at the University of North Carolina, also showed that vaporised hydrogen peroxide (VHP)…

Blood plasma from recovered COVID-19 patients: a promising approach

In a small clinical trial just granted approval, about 30 COVID-19 patients at Karolinska University Hospital may soon begin to receive blood plasma from people who have recovered from the disease. Sweden's Ethical Review Authority has approved the trial treatment, and its effectiveness will be evaluated in a study by researchers at Karolinska Institutet and the Karolinska University Hospital.…

Lung cancer screening: ESR welcomes release of NELSON trial results

The publication of the results of the Dutch-Belgian lung cancer screening trial (NELSON) supports recent calls to introduce lung cancer screening programmes throughout Europe. In light of the scientific evidence, lung cancer screening should be firmly embedded in any initiative launched by the European Commission and the Member States in the fight against cancer. As the leading cause of death…

Study reveals many unnecessary appendix surgeries in children

Surgery for appendicitis is the most common emergency operation in children. A new study has found that the UK has the highest reported national rate of ‘normal appendicectomy,’ where children undergo surgery for suspected appendicitis but laboratory examination of the removed appendix finds it to be normal. Although most children who are misdiagnosed as having appendicitis improve without…

New microsurgery robot shows promise

Supermicrosurgery – operations on vessels ranging from 0.3 to 0.8 millimeters – is limited by the dexterity of the surgeon’s hands. To bypass this limitation, robots can assist in the surgical process. One such robot is MUSA – the world’s first robotic platform for supermicrosurgery, which was co-developed by researchers from Eindhoven University of Technology (TU/e) and the TU/e…

Colon cancer surgery: why experience pays off

Patients with colorectal cancer have a greater chance of survival if they are operated in hospitals with a high case load. This is because complications that can occur after surgery can be better managed there. Tumours of the colon, so-called colorectal carcinomas, are the second to third most frequent tumours in women and men in Germany. The surgical removal of the tumours is a central component…
