What are anxiety disorders? 'Anxiety disorder' is an umbrella term which refers to mental health conditions including (but not limited to): • generalised anxiety disorder: when someone experiences...

How accurate are Truenat assays for detecting pulmonary tuberculosis and rifampicin resistance in adults and adolescents? Key messages – Truenat MTB Plus was more accurate than Truenat MTB for detecting pulmonary tuberculosis. Truenat MTB misidentified many people as having tuberculosis when they did not, which raises concern. – Xpert Ultra was more accurate than Truenat MTB. – Evidence on the accuracy of Truenat assay for detecting rifampicin was limited. What is pulmonary tuberculosis? Pulmonary tuberculosis is a lung disease caused by a bacterium (a germ) that spreads through the air via...

Does selecting targeted therapies based on genetic testing of an individual's cancer prolong their life or delay disease progression in people with advanced cancer? Key messages People with advanced cancers who received matched targeted therapies, either alone or in combination with standard treatments, experienced longer periods of disease control compared to those receiving standard treatments alone. However, the evidence on whether these therapies extend overall survival remains inconsistent. Further information is needed on the potential harms of matched targeted therapy and whether...

What are the effects of combined psychosocial interventions and medications for helping people who consume an excessive amount of alcohol? Key messages • Compared to psychosocial interventions alone, adding medications is probably safe and helpful for people with alcohol use disorder (AUD) in reducing alcohol use. • Due to the limited number of available studies, we do not know if combined psychosocial interventions and medications, when compared to medications alone or no treatment or usual care, is helpful for people with AUD. • More studies are needed looking at the effects of combined...

What influences people to fund, provide, and attend general health checks? Key messages • People decide to get general health checks based on several things, such as being aware of general health checks and getting reminders from family, friends, or healthcare providers. In places where general health checks and treatment are not free, resources like time and money also play a role. Some people avoid general health checks because they are afraid of bad results. • We found less information about healthcare funders and providers, so we do not fully understand what drives their decisions about...

Does the risk of death differ between female and male adult patients with pulmonary embolism (a blood clot in the lungs)? Key messages - We concluded that it is uncertain if sex (whether a patient is male or female) is an independent predictor of the risk of death in people with pulmonary embolism (a blood clot in the lungs), as our review found contradictory results. - We found a small but important reduction in death from any cause by 30 days after pulmonary embolism in female compared to male patients. However, in female patients, there may be a small but important increase in death...

Prognosis of surgically resected clinical stage 1A non-small cell lung cancers manifesting as a subsolid nodule on computed tomography including pure ground glass nodules This is a protocol for a Cochrane Review (prognosis). The objectives are as follows: To quantify the risk of tumour relapse/recurrence after a surgical resection of stage 1A non-small cell lung cancer (NSCLC) as manifested on computed tomography (CT) imaging as a subsolid nodule. This is a protocol....

Statins for preventing preeclampsia This is a protocol for a Cochrane Review (intervention). The objectives are as follows: To evaluate the relative benefits and harms of statins for preeclampsia prevention in pregnant women. This is a protocol....

Do different methods of nutritional support affect recovery and complications in adults after pancreaticoduodenectomy? Key messages - Enteral nutrition may not increase the risk of complications but is probably linked to a shorter hospital stay compared to parenteral nutrition. - When comparing jejunostomy feeding to oral nutrition, there may be no clear difference in complications or length of hospital stay, but the evidence is uncertain. - More evidence is needed to say with higher levels of confidence how these different types of feeding affect patients after a pancreaticoduodenectomy....

Safety and usefulness of proton pump inhibitors for preterm infants with reflux disease Key Messages - Reflux is common in preterm infants - The current evidence neither supports nor refutes the safety and efficacy (usefulness) of proton pump inhibitors (PPIs) for the treatment of reflux in preterm infants. What is gastroesophageal reflux, and how does it differ from gastroesophageal reflux disease? Gastroesophageal reflux happens when the stomach contents flow back into the esophagus (canal joining throat to stomach). It is common in a newborn. Premature infants are more likely to...

Can a class of antidiabetic medicine help protect the brain after a severe ischemic (caused by a blocked blood vessel) stroke? Key messages 1. There is limited evidence that glyburide (a sulfonylurea, or type of medicine used for type 2 diabetes) may have little to no effect on a person's function 90 days after a stroke, or the number of deaths after 90 days. It may have little to no effect on neurological deterioration within three days, such as consciousness, speech, or weakness, and probably has little to no effect on unwanted side effects, such as heart-related problems, or pneumonia. 2....

What are the benefits and risks of alternative models of delivering care for people with low back pain? Key messages - Compared to usual care, alternative care models probably do not appreciably improve the quality of care for people with low back pain in terms of referrals to or use of any lumbar spine imaging and prescription or use of opioids. - Alternative care models do not make an important difference to the level of pain or back-related function. - We are less certain of the effects on lumbar spine surgery, hospitalisation, and total adverse (unwanted or harmful) events. What is...

Renin inhibitors or angiotensin receptor blockers: which work better to treat hypertension? Key messages - The available evidence from short-term studies suggests there is probably little to no difference between renin inhibitors and angiotensin receptor blockers in terms of death rates, withdrawal due to unwanted effects, serious unwanted events, unwanted events, and blood pressure control for people with mild primary hypertension. - Due to a lack of strong evidence from long-term studies, any potential differences between these two drugs for measures of heart and blood vessel health are...

What are the best strategies to implement World Health Organization (WHO) recommendations to prevent, detect, and treat postpartum hemorrhage? Key messages Multicomponent implementation strategies may improve adherence to World Health Organization (WHO) postpartum hemorrhage (PPH) prevention recommendations and probably do not make a difference to intensive care unit (ICU) admissions, need for additional surgeries, or death of the mother. We do not know if multicomponent implementation strategies affect blood loss or blood transfusion. We do not know if single-component implementation...
