Do different ways of giving blood or blood products to treat bleeding affect the risk of death or the risk of developing a blood clot in people who are bleeding heavily after a traumatic injury? Key messages - No particular transfusion strategy (method of giving blood products) seems to change the overall chance of a patient dying or getting a blood clot. - We found 18 studies that tested different ways of giving blood transfusions. This variety made it difficult to combine the results and means we do not have clear answers to our questions. What is traumatic injury? A traumatic injury is a...

For those receiving a procedure to open up vessels after an ischaemic stroke, is clot-busting medicine better than no clot-busting medicine? Key messages For people who received a procedure to open up blood vessels after a stroke, adding a clot-busting medicine: did not make a difference, on average, in their ability to perform daily activities on their own with slight or moderate disability, in the number of deaths, or in bleeding inside the brain with or without symptoms. resulted in a higher flow of blood that could be seen going through the previously blocked blood vessels. What is acute...

Is entecavir better than no treatment or placebo for treating people with chronic hepatitis B? Key messages We could not estimate the effects of entecavir (a medicine used to treat infections caused by viruses) on death due to any cause in people with chronic hepatitis B (a common liver disease) as there were no deaths. No studies looked at health-related quality of life (a measure of a person's satisfaction with their life and health). We do not know whether entecavir is better than no treatment or placebo (a pretend treatment) regarding the proportion of people with serious harmful...

What factors influence caregivers’ and adolescents’ views and practices around human papillomavirus (HPV) vaccination for adolescents? Key messages • Many complex factors may influence caregivers’ and adolescents’ views and actions about human papillomavirus (HPV) vaccination for adolescents. We divided them into 8 themes relating to individual knowledge and perceptions, family and social relationships, and the wider contexts in which caregivers and adolescents live. • Healthcare planners and policy-makers could use the themes to help them understand specific contexts in which people are...

Antibiotics to prevent infection after surgery to manage miscarriage Key messages We are uncertain whether routine antibiotics have any effect on the risk of getting a uterine infection (infection in the womb) after surgery to manage a miscarriage, based on the combined results from all six trials. However, based on the results from only the well-done trials (85% of the total number of women in the studies), we are confident that routine antibiotics reduce the risk of getting a uterine infection after surgery to manage a miscarriage. We are uncertain whether routine antibiotics have any...

What are the benefits and risks of different types of surgery for people with presbyopia? Key Messages Based on current evidence, the relative benefits and risks of different types of surgery for treating people with presbyopia (difficulties in reading or seeing close up) are unclear at three to six months after treatment. There was no information about the effects beyond six months after treatment. No study looked at the balance of costs and how well the different treatments worked. Future well-designed studies should measure the longer-term benefits and risks of different types of surgery...

Scales to assess pain in newborn infants Key messages Clinical staff should be aware that the available rating scales for assessing pain in newborn infants are of very low quality. There is a need to develop these scales further. What are clinical rating scales? Since newborn infants cannot express their pain with words, staff need to assess their pain by looking at their behaviours and vital signs instead. Many different rating scales can be used for this, assessing infant pain through, for example, heart frequency, facial expression, and body movement. What did we want to find out? We...

Is switching to a different antipsychotic medicine better than continuing with the same one for people with non-responsive schizophrenia? Key messages • We do not know if people with non-responsive schizophrenia have better outcomes if they switch to a different antipsychotic medicine or continue with the same one because the evidence is very uncertain. • The few studies which looked at this question differed markedly from each other in terms of the antipsychotics used, study duration and definitions of initial non-response. • We need further large, well-conducted studies to shed light on...
