Mucolytics (drugs that break down mucus) for children with chronic suppurative lung disease Key messages - Due to a lack of robust evidence, it is unclear if mucolytics are helpful for children with chronic suppurative lung disease (CSLD). We found only one small study with design limitations. - Larger, well-designed studies are needed to assess the benefits and potential harms of mucolytic medications in children with CSLD. What is chronic suppurative lung disease (CSLD)? Chronic suppurative lung diseases are conditions associated with chronic infection and inflammation of the airways with...

What are the effects of ultrasound versus anatomic landmark guidance for percutaneous common femoral artery access? Key messages • Ultrasound guidance may lead to a higher first-attempt success rate and improved time to successful common femoral artery (CFA) access, while reducing the venipuncture rate (unintentionally accessing the vein instead of the targeted artery) and number of access attempts, compared to anatomic landmark guidance. • Further research is needed to increase our confidence in the evidence. What is the condition, and how is it treated? Percutaneous (through the skin)...

Do amphetamines increase blood pressure? Key messages • Amphetamines are substances that increase activity in the brain and central nervous system. Taking them every day by mouth for at least 8 weeks increases blood pressure and heart rate. • In studies that gave participants amphetamines or placebo medicine (an inactive substance), more people given amphetamines quit the studies due to unwanted or harmful effects than people given placebo. What are amphetamines, and what are they prescribed for? Amphetamines are medicines that have a stimulant effect on the brain. They can make you more...

What are the effects of oral decongestants on blood pressure? Key messages – We found no evidence that taking oral decongestants (medicine taken by mouth to relieve a stuffy nose) daily for a week or more changes blood pressure or heart rate or causes people to stop taking them due to unwanted effects. – There were only a few studies, and they were not well designed. More well-conducted studies are needed. – Given that oral decongestants are sometimes taken daily for weeks or months, and have the potential to increase blood pressure, people should consider this potential risk alongside the...

What are the likely benefits and harms of non-medicine and non-surgical treatments for non-specific low back pain? Key messages For acute low back pain (pain lasting less than 6 weeks) • Advice to stay active probably reduces pain and improves function compared to advice to rest in bed. For subacute low back pain (pain lasting from 6 to 12 weeks) • Multidisciplinary therapies probably reduce pain compared to usual care. • Spinal manipulation probably does not improve function compared to placebo (a 'sham' or 'dummy' treatment designed to resemble the actual treatment but lacking active...

Can antibiotics clear or suppress infection with non-tuberculous mycobacteria in the lungs of people with cystic fibrosis? Key messages There is a lack of evidence to inform guidelines about antibiotic treatment for non-tuberculous mycobacteria in people with cystic fibrosis. Larger and more standardised studies looking at both laboratory results and symptoms are needed before we can make meaningful comparisons between different antibiotic treatments. What is cystic fibrosis? Cystic fibrosis is a genetic condition (when both parents pass the cystic fibrosis gene to their children) and people...

What are the benefits and risks of using a combination of treatments to manage cachexia (disease-related wasting)? Key messages: • We do not know if combinations of two or more treatments (of medication, diet, and exercise) benefit people who have or are at risk of developing cachexia (disease-related wasting). This is because there are currently not enough robust studies in this area. • We need future research to increase our confidence in the evidence by conducting better designed and larger studies. What is cachexia? Cachexia is a complex metabolic syndrome that occurs in people with...

Perceptions and experiences of the prevention, identification and management of pre-eclampsia and eclampsia: a qualitative evidence synthesis This is a protocol for a Cochrane Review (qualitative). The objectives are as follows: The overall objective of this qualitative evidence synthesis is to describe and explore the perceptions and experiences of key stakeholders who have experience with pre-eclampsia/eclampsia or its prevention, identification, or management. The key stakeholders are women who have experienced pre-eclampsia/eclampsia, people in the community, lay health workers, and...

How accurate are GAD-7 and GAD-2 questionnaires for detecting anxiety disorders? Key messages • The GAD-7 and GAD-2 questionnaires alone cannot be used to diagnose or rule out an anxiety disorder. • However, they provide an indication of whether an anxiety disorder may be present. • The interpretation of a "negative" or "positive" questionnaire finding of an individual depends on the context. 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...

Mitral repair with annuloplasty for moderate ischemic mitral regurgitation in people undergoing coronary artery bypass surgery This is a protocol for a Cochrane Review (intervention). The objectives are as follows: To assess the effects of mitral repair with annuloplasty for moderate ischemic mitral regurgitation in people undergoing coronary artery bypass grafting. This is a protocol....

Perioperative glucocorticoid supplementation in pituitary surgery This is a protocol for a Cochrane Review (intervention). The objectives are as follows: To assess the effects, including benefits and harms, of perioperative glucocorticoid supplementation in people undergoing surgery for pituitary neuroendocrine tumours (PitNETs) with a preoperatively intact hypothalamic-pituitary-adrenal axis. This is a protocol....

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....

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...
