ReviewPeriodontal therapy for primary or secondary prevention of cardiovascular disease in people with periodontitis.
There may be an association between periodontitis and cardiovascular disease (CVD); however, the evidence so far has been uncertain about whether periodontal therapy can help prevent CVD in people diagnosed with chronic periodontitis. This is the third update of a review originally published in 2014, and most recently updated in 2019. Although there is a new multidimensional staging and grading system for periodontitis, we have retained the label 'chronic periodontitis' in this version of the review since available studies are based on the previous classification system. ⋯ For primary prevention of cardiovascular disease (CVD) in people diagnosed with periodontitis and metabolic syndrome, very low-certainty evidence was inconclusive about the effects of scaling and root planning plus antibiotics compared to supragingival scaling. There is no reliable evidence available regarding secondary prevention of CVD in people diagnosed with chronic periodontitis and CVD. Further trials are needed to reach conclusions about whether treatment for periodontal disease can help prevent occurrence or recurrence of CVD.

ReviewUpper limb exercise for arteriovenous fistula maturation in people requiring permanent haemodialysis access.
The failure of arteriovenous fistulas (AVF) to mature is a major problem in patients with kidney failure who require haemodialysis (HD). Preoperative planning is an important factor in increasing functional AVF. Upper limb exercise has been recommended to gain AVF maturation. Studies of pre- and post-operative upper limb exercises in patients with kidney failure patients have been reported; however, the optimal program for this population is unknown due to inconsistent results among these programs. ⋯ Our findings suggest that the current research evidence examining upper limb exercise programs is of low quality, attributable to variability in the type of interventions used and the overall low number of studies and participants.

Review Meta AnalysisElectromagnetic-guided versus endoscopic-guided postpyloric placement of nasoenteral feeding tubes.
For people who are malnourished and unable to consume food by mouth, nasoenteral feeding tubes are commonly used for the administration of liquid food and drugs. Postpyloric placement is when the tip of the feeding tube is placed beyond the pylorus, in the small intestine. Endoscopic-guided placement of postpyloric feeding tubes is the most common approach. Usually, an endoscopist and two or more medical professionals perform this procedure using a guidewire technique. The position of the tube is then confirmed with fluoroscopy or radiography, which requires moving people undergoing the procedure to the radiology department. Alternatively, electromagnetic-guided placement of postpyloric nasoenteral feeding tubes can be performed by a single trained nurse, at the bedside and with less equipment than endoscopic-guided placement. Hence, electromagnetic-guided placement may represent a promising alternative to endoscopic-guided placement, especially in settings where endoscopy and radiographic facilities are unavailable or difficult to access. ⋯ We found low-certainty evidence that electromagnetic-guided placement at the bedside results in little to no difference in technical success in insertion and aspiration pneumonitis, compared to endoscopic-guided placement. The heterogeneity of the healthcare professionals who performed the procedures and the small sample sizes limited our confidence in the evidence. Future research should be based on large studies with well-defined endpoints to potentially elucidate the differences between these two procedures.

Review Meta AnalysisPharmacological interventions for prevention of weight gain in people with schizophrenia.
Antipsychotic-induced weight gain is an extremely common problem in people with schizophrenia and is associated with increased morbidity and mortality. Adjunctive pharmacological interventions may be necessary to help manage antipsychotic-induced weight gain. This review splits and updates a previous Cochrane Review that focused on both pharmacological and behavioural approaches to this problem. ⋯ There is low-certainty evidence to suggest that metformin may be effective in preventing weight gain. Interpretation of this result and those for other agents, is limited by the small number of studies, small sample size, and short study duration. In future, we need studies that are adequately powered and with longer treatment durations to further evaluate the efficacy and safety of interventions for managing weight gain.
