Review Meta AnalysisPreoperative coronary interventions for preventing acute myocardial infarction in the perioperative period of major open vascular or endovascular surgery.
Postoperative myocardial infarction (POMI) is associated with major surgeries and remains the leading cause of mortality and morbidity in people undergoing vascular surgery, with an incidence rate ranging from 5% to 20%. Preoperative coronary interventions, such as coronary artery bypass grafting (CABG) or percutaneous coronary interventions (PCI), may help prevent acute myocardial infarction in the perioperative period of major vascular surgery when used in addition to routine perioperative drugs (e.g. statins, angiotensin-converting enzyme inhibitors, and antiplatelet agents), CABG by creating new blood circulation routes that bypass the blockages in the coronary vessels, and PCI by opening up blocked blood vessels. There is currently uncertainty around the benefits and harms of preoperative coronary interventions. ⋯ Preoperative coronary interventions plus usual care may have little or no effect on preventing perioperative acute myocardial infarction and reducing perioperative all-cause mortality compared to usual care, but the evidence is very uncertain. Similarly, limited, very low-certainty evidence shows that preoperative coronary interventions may have little or no effect on reducing long-term all-cause mortality. There is very low-certainty evidence that preoperative coronary interventions plus usual care may prevent long-term myocardial infarction, and low-certainty evidence that they may reduce length of hospital stay slightly, but not cardiovascular mortality in the short term, when compared to usual care alone. Adverse effects of preoperative coronary interventions were poorly reported in trials. Quality of life and vessel or graft patency were not reported. We downgraded the certainty of the evidence most frequently for high risk of bias, inconsistency, or imprecision. None of the analysed trials provided significant data on subgroups of patients who could potentially experience more substantial benefits from preoperative coronary intervention (e.g. altered ventricular ejection fraction). There is a need for evidence from larger and homogeneous RCTs to provide adequate statistical power to assess the role of preoperative coronary interventions for preventing acute myocardial infarction in the perioperative period of major open vascular or endovascular surgery.

Immunotherapy for non-small cell lung cancer in the elderly population: a generic protocol.
This is a protocol for a Cochrane Review (intervention). The objectives are as follows: To evaluate the effectiveness and safety of immune checkpoint inhibitors (ICI) as monotherapy or in combination compared to standard of care for elderly people (≥ 65 years) with non-small cell lung cancer (NSCLC).

Review Meta AnalysisPeripherally inserted central catheter design and material for reducing catheter failure and complications.
Peripherally inserted central catheters (PICCs) facilitate diagnostic and therapeutic interventions in health care. PICCs can fail due to infective and non-infective complications, which PICC materials and design may contribute to, leading to negative sequelae for patients and healthcare systems. ⋯ There is limited high-quality RCT evidence available to inform clinician decision-making for PICC materials and design. Limitations of the current evidence include small sample sizes, infrequent events, and risk of bias. There may be little to no difference in the risk of VTE, PICC-associated BSI, occlusion, or mortality across PICC materials and designs. Further rigorous RCTs are needed to reduce uncertainty.

Review Meta AnalysisTopical fluoride as a cause of dental fluorosis in children.
This is an update of a review first published in 2010. Use of topical fluoride has become more common over time. Excessive fluoride consumption from topical fluorides in young children could potentially lead to dental fluorosis in permanent teeth. ⋯ Most evidence identified mild fluorosis as a potential adverse outcome of using topical fluoride at an early age. There is low- to very low-certainty and inconclusive evidence on the risk of having fluorosis in permanent teeth for: when a child starts receiving topical fluoride varnish application; toothbrushing with fluoride toothpaste; the amount of toothpaste used by the child; and the frequency of toothbrushing. Moderate-certainty evidence from RCTs showed that children who brushed with 1000 ppm or more fluoride toothpaste from one to two years of age until five to six years of age probably had an increased chance of developing dental fluorosis in permanent teeth. It is unethical to propose new RCTs to assess the development of dental fluorosis. However, future RCTs focusing on dental caries prevention could record children's exposure to topical fluoride sources in early life and evaluate the dental fluorosis in their permanent teeth as a long-term outcome. In the absence of these studies and methods, further research in this area will come from observational studies. Attention needs to be given to the choice of study design, bearing in mind that prospective controlled studies will be less susceptible to bias than retrospective and uncontrolled studies.
