What is cancer-related fatigue? Cancer-related fatigue is a feeling of extreme tiredness that lasts for a long time. It can come from cancer or cancer therapy, or both. Cancer-related fatigue affects both the body...

Do biosimilar monoclonal antibodies perform as well as the original medicine for cancer treatment? Key messages – For people with lung, colorectal (a cancer that develops in the colon or rectum), non-Hodgkin's lymphoma (type of blood cancer), or breast cancers, bevacizumab, rituximab, and trastuzumab biosimilars (products similar to a medicine made from living organisms) or original (called originator) medicines have similar effects on outcomes considered important by consumers. – The length of time people are alive and cancer-free after the start of treatment was similar between biosimilar...

Why is improving the diagnosis of BK polyomavirus-associated nephropathy (BKPyVAN) important? Key messages • The studies in this review suggest that testing for BK polyomavirus in blood samples is a reliable screening tool for detecting BKPyVAN. • Using a blood BK virus level of 10,000 or more copies/mL, the chances of missing a diagnosis of BKPyVAN was 6 patients per 1000 and wrongly diagnosing BKPyVAN when a patient did not have it was 48 per 1000. • Using a blood BK virus level of 2000 or more copies/mL, the chances of missing a diagnosis of BKPyVAN was 5 patients per 1000, and wrongly...

What are the benefits and risks of fenoldopam for preventing or treating acute kidney injury? Key messages • Fenoldopam (a medicine that rapidly widens and relaxes blood vessels) probably reduces the risk of developing acute kidney injury (AKI) (a condition where the kidneys suddenly lose their ability to filter waste from the blood) in people who are at risk of developing AKI compared to placebo (dummy medicine) or saline (salt solution). • Fenoldopam may reduce the time spent in intensive care compared to placebo or saline. • Fenoldopam, compared to other active medicines (dopamine and...

Psychotherapeutic treatments for depression in older adults This is a protocol for a Cochrane Review (intervention).

This is a protocol....

Do heart surgery patients benefit from preventive treatment with inotropic drugs? Key messages • Treatment of heart surgery patients with the drug ‘levosimendan’ before surgery may be beneficial. • However, the current evidence is limited, and more studies are needed before definitive recommendations can be made. Rationale Reduced heart function is a potentially fatal complication after heart surgery. A possible approach to prevent this complication is treatment with drugs that stimulate the contraction of the heart (so-called inotropic agents). What did we want to find out? We assessed...

Do drugs that enhance the beating force of the heart prevent low cardiac output syndrome and death in children undergoing surgery for congenital heart disease? Key messages - Using levosimendan as a prevention makes it less likely that children undergoing heart surgery will die. The risk for reduced heart function is largely decreased with levosimendan and likely also with milrinone, compared to placebo. Side effects are likely more common with levosimendan or dobutamine and may be more common with milrinone but less common with low-dose milrinone, compared to placebo. - Our confidence in...

Glucocorticoid facet joint injection for chronic back or neck pain This is a protocol for a Cochrane Review (intervention). The objectives are as follows: The primary objective is to assess the benefits and harms of glucocorticoid facet joint injections in adults with chronic back or neck pain that is presumed to be facet joint-mediated. The secondary objective is to assess whether the effects differ by diagnostic method for facet joint-mediated pain. This is a protocol....

Is omega-3 polyunsaturated fatty acid supplementation better than a placebo for treating depression among children and adolescents? Key messages – Due to a lack of robust evidence, the benefits and unwanted effects of omega-3 polyunsaturated fatty acids (which are important fats that you must obtain from your diet) supplementation for treating depression among children and adolescents are unclear. – Larger, well-designed studies are needed to give better estimates of the potential benefits and harms of omega-3 polyunsaturated fatty acid supplementation for child and adolescent depression....

Methylxanthines for the prevention or treatment of intermittent hypoxemia or respiratory insufficiency in late preterm infants This is a protocol for a Cochrane Review (intervention). The objectives are as follows: To assess the benefits and harms of methylxanthines in preventing or treating intermittent hypoxemia or respiratory insufficiency in late preterm infants. This is a protocol....

Vaccines for preventing Ebola virus disease This is a protocol for a Cochrane Review (intervention). The objectives are as follows: To assess the effects of vaccines to prevent Ebola virus disease in people who have been, or have potentially been, exposed to Ebola virus. This is a protocol....

Virtual reality technology for pain management in advanced cancer This is a protocol for a Cochrane Review (intervention). The objectives are as follows: Primarily, to determine the effectiveness of a virtual reality (VR) intervention compared to an alternative or no intervention for people living with advanced cancer: on pain intensity, adverse events (AEs) and serious adverse events (SAEs); and secondarily, on additional pain properties (e.g. type, frequency), psychological well-being, other physical symptoms (e.g. anxiety) and quality of life. We will also report on the context in which...

Minimizing blood sampling in preterm infants This is a protocol for a Cochrane Review (intervention). The objectives are as follows: To assess the benefits and harms of different strategies to minimize blood sampling in preterm infants. This is a protocol....

What are the benefits and risks of tranexamic acid for preventing heavy bleeding after caesarean births? Key messages The clotting medicine tranexamic acid (TXA) given during caesarean birth does not prevent heavy bleeding when blood loss is measured by collecting blood and weighing surgical sponges, or when health providers estimate the amount of blood loss. When blood loss is calculated using the proportion of red blood cells in blood before and after the caesarean birth, there is likely a slight reduction in heavy bleeding. TXA probably does not make a difference in the number of women...

Support for parents and families after stillbirth and neonatal death This is a protocol for a Cochrane Review (intervention). The objectives are as follows: To identify and assess the effect of support interventions focused on psychological, social, and emotional outcomes for bereaved parents (including birth and non-birthing mothers, fathers, partners) and family members of parents (e.g. grandparents; siblings) who have experienced stillbirth or neonatal death. This is a protocol....

Is silver diamine fluoride varnish an effective treatment for preventing and managing tooth decay in children and adults? Key messages - We can't tell if silver diamine fluoride (SDF) is better than no treatment at preventing or treating tooth decay. - We can't tell if SDF is better or worse than other treatments at preventing or treating tooth decay. - New studies could help to find out about the unwanted effects of SDF, whether people are bothered by the staining on the teeth caused by SDF, and the best treatment approach. What is tooth decay? Tooth decay happens when bacteria in your...

Does taking statins prevent blood clots from forming in the veins of people who have not previously had a blood clot? Key messages - Statin use for the primary prevention of venous thromboembolism (VTE; a condition in which a blood clot, or embolism, forms in the vein) may slightly decrease the incidence of VTE and death from any cause, but the reduction may be too small to be important. - Statins may make no difference to the likelihood of experiencing deep vein thrombosis (DVT; a blood clot in the lower legs), pulmonary embolism (PE; a blood clot in the lungs), or myopathy (a condition...
