Review Meta AnalysisTopical silver diamine fluoride (SDF) for preventing and managing dental caries in children and adults.
Dental caries is the world's most prevalent disease. Untreated caries can cause pain and negatively impact psychosocial health, functioning, and nutrition. It is important to identify cost-effective, easy-to-use agents, which can prevent or arrest caries. This review evaluates silver diamine fluoride (SDF). ⋯ In the primary dentition, evidence remains uncertain whether SDF prevents new caries or progression of existing caries compared to placebo or no treatment, but it may offer benefit over placebo or no treatment in caries arrest. Compared to placebo or no treatment, SDF probably also helps prevent new root caries. However, the evidence is uncertain for other caries outcome measures in this dentition and in all caries outcomes for coronal surfaces of permanent dentition. Compared to flouride varnish, SDF may offer little or no benefit in preventing new caries in the primary dentition, but the evidence is very uncertain for other caries outcome measures in the primary dentition and for preventing new caries in the permanent dentition. We were unable to establish whether one SDF treatment approach was better than another, or how SDF compared to other treatments, because of very low-certainty evidence. The impact of SDF staining of teeth was poorly reported and the evidence for adverse effects is very uncertain. Additional well-conducted studies are needed. These should measure the impact of staining and be analysed to take account of clustering issues within participants.

Review Meta AnalysisBone marrow versus peripheral blood allogeneic haematopoietic stem cell transplantation for haematological malignancies in adults.
Allogeneic haematopoietic stem cell transplantation (allo-HSCT) is an established treatment option for many malignant and non-malignant haematological disorders. Peripheral blood stem cells represent the main stem cell source in malignant diseases due to faster engraftment and practicability issues compared with bone marrow stem cells. Since the early 2000s, there have been many developments in the clinical field. Allo-HSCT using haploidentical family donors (haplo-HSCT) has emerged as an alternative for people who do not have human leukocyte antigen (HLA)-matched siblings or unrelated donors. In addition, the introduction of new methods and strategies in allo-HSCT, such as the use of post-transplant cyclophosphamide (PT-Cy), better donor selection, the more frequent administration of anti-thymocyte globulins (ATGs), but also improved management of side effects such as graft-versus-host disease (GvHD) and infection, have impacted outcomes after allo-HSCT. In addition, as transplant indications and strategies continue to adapt in line with novel research findings, the effect of the stem cell source on post-transplant outcomes is unclear. For our analysis, we considered peripheral blood stem cells as the standard graft source for adults with haematological malignancies. This is an update of a review first published in 2014. ⋯ Moderate-certainty evidence suggests little to no difference in overall survival following allo-HSCT using bone marrow versus peripheral blood stem cells (the current clinical standard stem cell source). Low-certainty evidence suggests little to no difference between the stem cell sources in terms of disease-free survival and non-relapse or transplant-related survival. BMT likely reduces the risk of extensive chronic GvHD and overall chronic GvHD compared with PBSCT. Evidence from two RCTs suggests that BMT compared with PBSCT may result in higher long-term quality of life, possibly due to the lower chronic GvHD incidence. With this update, we aimed to supply the most recent data on the choice of stem cell source for allo-HSCT in adults by including new evidence published up to November 2022. We identified no new ongoing studies and no new RCTs with published results. Further research in this field is warranted.

This is a protocol for a Cochrane Review (intervention). The objectives are as follows: To assess the effects of antipsychotic drugs (both first- and second-generation antipsychotics) compared to placebo on body weight gain, psychological symptoms, acceptability, and adverse events for people with anorexia nervosa.

Review Meta AnalysisLow dialysate sodium levels for chronic haemodialysis.
Cardiovascular (CV) disease is the leading cause of death in dialysis patients and is strongly associated with fluid overload and hypertension. It is plausible that low dialysate sodium ion concentration [Na+] may decrease total body sodium content, thereby reducing fluid overload and hypertension and ultimately reducing CV morbidity and death. This is an update of a review first published in 2019. ⋯ Low dialysate [Na+] reduces intradialytic weight gain and probably blood pressure, which are effects directionally associated with improved outcomes. However, the intervention probably increases intradialytic hypotension and probably reduces serum [Na+], effects that are associated with an increased risk of death. The effect of the intervention on overall patient health and well-being is unknown. Further evidence is needed in the form of longer-term studies in contemporary settings, evaluating end-organ effects in small-scale mechanistic studies using optimal methods, and clinical outcomes in large-scale multicentre RCTs.

Review Meta AnalysisStatins for the primary prevention of venous thromboembolism.
Venous thromboembolism (VTE) involves the formation of a blood clot in a vein, and includes deep venous thrombosis (DVT) or pulmonary embolism (PE). The annual incidence for VTE varies from 0.75 to 2.69 per 1000 individuals, with about 40 million people worldwide impacted by VTE. Statins, 3-hydroxy-3-methylglutaryl (HMG)-coenzyme A (CoA) reductase inhibitors, inhibit cholesterol biosynthesis and display several vascular-protective effects, including antithrombotic properties. However, the potential role of statins in the primary prevention of VTE is still not clear. ⋯ Using statins for the primary prevention of VTE may slightly reduce the incidence of VTE and all-cause mortality. However, this effect is likely too weak to be considered significant. Statin use may not decrease the occurrence of DVT and PE. The current evidence is insufficient to draw strong conclusions because of the risk of bias in the studies, imprecision in the effect estimates, and potential publication bias. More evidence from well conducted and fully reported RCTs is needed to assess the preventive effects of different types of statins, as well as the effects of different dosages and treatment durations in various populations.
