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 AnalysisSingle-incision versus conventional multi-incision laparoscopic appendicectomy for suspected uncomplicated appendicitis.
Appendicectomy is a well-established surgical procedure to manage acute appendicitis. The operation was historically performed as an open procedure and is currently performed using minimally invasive surgical techniques. A recent development in appendicectomy technique is the introduction of single-incision laparoscopic surgery. This incorporates all working ports (either one multi-luminal port or multiple mono-luminal ports) through a single skin incision; the procedure is known as single-incision laparoscopic appendicectomy or SILA. Unanswered questions remain regarding the efficacy of this novel technique, including its effects on patient benefit and satisfaction, complications, and long-term outcomes, when compared to multi-incision conventional laparoscopy (CLA). This is an update of a review published in 2011. ⋯ There is low-to-moderate certainty evidence that single-incision laparoscopic appendicectomy is comparable to conventional laparoscopic appendicectomy in terms of complications, length of hospital stay, return to normal activities, and postoperative pain in the first 24 hours. The disadvantage of SILA may be a higher conversion rate, but SILA is probably associated with better patient cosmetic satisfaction.

Larger versus smaller red blood cell volume per transfusion in hospitalized adults, children, and preterm neonates.
This is a protocol for a Cochrane Review (intervention). The objectives are as follows: The objective of this review is to compare the effectiveness and safety of larger versus smaller RBC volume per transfusion for anemia in hospitalized adults, children, and preterm neonates.
