ReviewTourniquet use for people with peripheral arterial disease undergoing major lower limb amputations.
At least 7000 major lower limb amputations (MLLAs) are performed in the UK each year, 80% of which are due to peripheral arterial disease (PAD). Intraoperative blood loss can have a deleterious effect on patient outcomes, and its replacement with transfused blood is not without risk. Tourniquets can be used in lower limb surgical procedures to provide a bloodless surgical field, minimise intraoperative blood loss, and reduce perioperative blood transfusion requirements. Although their safety has been demonstrated in certain orthopaedic operations, their use among people with PAD undergoing MLLA remains controversial. Many clinicians are concerned about tourniquets potentially compromising perfusion of the stump and thereby impacting wound healing through direct tissue injury, damage to the arterial supply of the wound, or both. ⋯ This review identified only one small historical RCT evaluating tourniquet use in MLLA. Tourniquets appeared to reduce intraoperative blood loss, drop in haemoglobin, and blood transfusion requirements following transtibial amputations for people with PAD. However, it is unclear whether tourniquets affect wound healing, stump revision rates, postoperative complications, or mortality. High-certainty evidence is required to inform clinical decision-making for the use of tourniquets in these patients.

Peyronie's disease is a condition that results in the development of penile plaques that can lead to penile curvature, pain, and erectile dysfunction, making sexual activity difficult. A number of non-surgical interventions exist to improve this condition, which include topical and injection agents as well as mechanical methods; however, their effectiveness remains uncertain. We performed this review to determine the effects of these non-surgical treatments. ⋯ There is little evidence supporting the effectiveness of most non-surgical treatments for Peyronie's disease. Existing trials are mostly of poor methodological quality and/or fail to address patient-centered outcomes. Injectional collagenase appears to have some effectiveness; however, many individuals may not experience the improvement as clinically relevant, and this comes with the risk of increased adverse events. There is a critical need for better non-surgical treatment options for men with Peyronie's disease.

Review Meta AnalysisVedolizumab for induction and maintenance of remission in Crohn's disease.
Vedolizumab blocks inflammatory activity within the gastrointestinal tract. Systematic reviews have demonstrated the efficacy of vedolizumab in ulcerative colitis and inflammatory bowel disease in general. This systematic review and meta-analysis summarises the current evidence of vedolizumab in the induction and maintenance of remission in Crohn's disease. ⋯ High-certainty data across four induction and three maintenance trials demonstrate that vedolizumab is superior to placebo in the induction and maintenance of remission in Crohn's disease. Overall adverse events are probably similar and serious adverse events may be similar between vedolizumab and placebo during both induction and maintenance phases of treatment. Head-to-head research comparing the efficacy and safety of vedolizumab to other biological therapies is required.

ReviewMobile phone-based interventions for improving contraception use.
Contraception provides significant benefits for women's and children's health, yet many women have an unmet need for contraception. Rapid expansion in the use of mobile phones in recent years has had a dramatic impact on interpersonal communication. Within the health domain text messages and smartphone applications offer means of communication between clients and healthcare providers. This review focuses on interventions delivered by mobile phone and their effect on use of contraception. ⋯ This review demonstrates there is evidence to support the use of mobile phone-based interventions in improving the use of contraception, with moderate-certainty evidence. Interactive mobile phone interventions appear more effective than unidirectional methods. The cost-effectiveness, cost benefits, safety and long-term effects of these interventions remain unknown, as does the evidence of this approach to support contraception use among specific populations. Future research should investigate the effectiveness and safety of mobile phone-based interventions with better quality trials to help establish the effects of interventions delivered by mobile phone on contraception use. This review is limited by the quality of the studies due to flaws in methodology, bias or imprecision of results.

ReviewEarly versus late removal of urinary catheter after kidney transplantation.
The optimal treatment for end-stage kidney disease is kidney transplantation. During the operation, a catheter is introduced into the bladder and remains in place postoperatively to allow the bladder to drain. This decreases tension from the cysto-ureteric anastomosis and promotes healing. Unfortunately, urinary catheters can pose an infection risk to patients as they allow bacteria into the bladder, potentially resulting in a urinary tract infection (UTI). The longer the catheter remains in place, the greater the risk of developing a UTI. There is no consensus approach to the time a catheter should remain in place post-transplant. Furthermore, the different timings of catheter removal are thought to be associated with different incidences of UTI and postoperative complications, such as anastomotic breakdown. ⋯ A high-quality, well-designed RCT is required to compare the effectiveness of early catheter removal versus late catheter removal in patients following a kidney transplant. At the present time, there is insufficient evidence to suggest any difference between early and late catheter removal post-transplant, and the studies investigating this were generally of poor quality.
