Review Meta AnalysisVegan dietary pattern for the primary and secondary prevention of cardiovascular diseases.
Diet plays a major role in the aetiology of cardiovascular disease (CVD) and as a modifiable risk factor is the focus of many prevention strategies. Recently vegan diets have gained popularity and there is a need to synthesise existing clinical trial evidence for their potential in CVD prevention. ⋯ Studies were generally small with few participants contributing to each comparison group. None of the included studies report on CVD clinical events. There is currently insufficient information to draw conclusions about the effects of vegan dietary interventions on CVD risk factors. The eight ongoing studies identified will add to the evidence base, with all eight reporting on primary prevention. There is a paucity of evidence for secondary prevention.

Belimumab, the first biologic approved for the treatment of systemic lupus erythematosus (SLE), has been shown to reduce autoantibody levels in people with SLE and help control disease activity. ⋯ The six studies that provided evidence for benefits and harms of belimumab were well-designed, high-quality RCTs. At the FDA-approved dose of 10 mg/kg, based on moderate to high-certainty data, belimumab was probably associated with a clinically meaningful efficacy benefit compared to placebo in participants with SLE at 52 weeks. Evidence related to harms is inconclusive and mostly of moderate to low-certainty evidence. More data are needed for the longer-term efficacy of belimumab.

Review Meta AnalysisInterventions for treating fractures of the patella in adults.
Fractures of the patella (kneecap) account for around 1% of all human fractures. The treatment of these fractures can be surgical or conservative (such as immobilisation with a cast or brace). There are many different surgical and conservative interventions for treating fractures of the patella in adults. This is an update of a Cochrane Review first published in 2015. ⋯ There is very limited evidence from nine RCTs and two quasi-RCTs on the relative effects of different surgical interventions for treating fractures of the patella in adults. There is no evidence from trials evaluating the relative effects of surgical versus conservative treatment or different types of conservative interventions. Given the very low-quality evidence, we are uncertain whether methods of percutaneous osteosynthesis give better results than conventional open surgery; whether cable pin system (open or percutaneous surgery) gives better results than the tension band technique; and whether biodegradable implants are better than metallic implants for displaced patellar fractures. Further randomised trials are needed, but, to optimise research effort, these should be preceded by research that aims to identify priority questions.

Review Meta AnalysisEndometrial resection and ablation versus hysterectomy for heavy menstrual bleeding.
Heavy menstrual bleeding (HMB) is common in otherwise healthy women of reproductive age, and can affect physical health and quality of life. Surgery is usually a second-line treatment of HMB. Endometrial resection/ablation (EA/ER) to remove or ablate the endometrium is less invasive than hysterectomy. Hysterectomy is the definitive treatment and can be via open (laparotomy) approach, or via minimally invasive approaches (vaginally or laparoscopically). Each approach has its own advantages and risk profile. ⋯ Endometrial resection/ablation (EA/ER) offers an alternative to hysterectomy as a surgical treatment for HMB. Effectiveness varies with EA/ER compared to different hysterectomy approaches. The perception of improvement in HMB with EA/ER is probably lower compared to open and unspecified route of hysterectomy, but may be similar compared to minimally invasive. Quality of life with EA/ER is probably similar to open and unspecified route of hysterectomy, but lower compared to minimally invasive hysterectomy. Further surgery for treatment failure is probably more likely with EA/ER compared to all routes of hysterectomy. Satisfaction rates also vary. EA/ER probably has a similar rate of satisfaction compared to open and unspecified route of hysterectomy, but a lower rate of satisfaction compared to minimally invasive hysterectomy. The proportion having any serious adverse event appears similar in all groups, but specific adverse events did reported difference between EA/ER and different routes. We were unable to draw conclusions about the time to return to normal activity, but the direction of effect suggests it is likely to be shorter with EA/ER.

Review Meta AnalysisSigns and symptoms to determine if a patient presenting in primary care or hospital outpatient settings has COVID-19.
The clinical implications of SARS-CoV-2 infection are highly variable. Some people with SARS-CoV-2 infection remain asymptomatic, whilst the infection can cause mild to moderate COVID-19 and COVID-19 pneumonia in others. This can lead to some people requiring intensive care support and, in some cases, to death, especially in older adults. Symptoms such as fever, cough, or loss of smell or taste, and signs such as oxygen saturation are the first and most readily available diagnostic information. Such information could be used to either rule out COVID-19, or select patients for further testing. This is an update of this review, the first version of which published in July 2020. ⋯ The majority of individual signs and symptoms included in this review appear to have very poor diagnostic accuracy, although this should be interpreted in the context of selection bias and heterogeneity between studies. Based on currently available data, neither absence nor presence of signs or symptoms are accurate enough to rule in or rule out COVID-19. The presence of anosmia or ageusia may be useful as a red flag for COVID-19. The presence of fever or cough, given their high sensitivities, may also be useful to identify people for further testing. Prospective studies in an unselected population presenting to primary care or hospital outpatient settings, examining combinations of signs and symptoms to evaluate the syndromic presentation of COVID-19, are still urgently needed. Results from such studies could inform subsequent management decisions.
