Review Meta AnalysisTamoxifen for adults with hepatocellular carcinoma.
Hepatocellular carcinoma is the most common type of liver cancer, accounting for 70% to 85% of individuals with primary liver cancer. Tamoxifen has been evaluated in randomised clinical trials in people with hepatocellular cancer. The reported results have been inconsistent. ⋯ Protocol available via DOI: 10.1002/14651858.CD014869.

Review Meta AnalysisTransarterial (chemo)embolisation versus systemic chemotherapy for colorectal cancer liver metastases.
The liver is affected by two groups of malignant tumours: primary liver cancers and liver metastases. Liver metastases are significantly more common than primary liver cancer, and five-year survival after radical surgical treatment of liver metastases ranges from 28% to 50%, depending on primary cancer site. However, R0 resection (resection for cure) is not feasible in most people; therefore, other treatments have to be considered in the case of non-resectability. One possible option is based on the concept that the blood supply to hepatic tumours originates predominantly from the hepatic artery. Transarterial chemoembolisation (TACE) of the peripheral branches of the hepatic artery can be achieved by administering a chemotherapeutic drug followed by vascular occlusive agents and can lead to selective necrosis of the cancer tissue while leaving normal liver parenchyma virtually unaffected. The entire procedure can be performed without infusion of chemotherapy and is then called bland transarterial embolisation (TAE). These procedures are usually applied over a few sessions. Another possible treatment option is systemic chemotherapy which, in the case of colorectal cancer metastases, is most commonly performed using FOLFOX (folinic acid, 5-fluorouracil, and oxaliplatin) and FOLFIRI (folinic acid, 5-fluorouracil, and irinotecan) regimens applied in multiple sessions over a long period of time. These therapies disrupt the cell cycle, leading to death of rapidly dividing malignant cells. Current guidelines determine the role of TAE and TACE as non-curative treatment options applicable in people with liver-only or liver-dominant metastatic disease that is unresectable or non-ablatable, and in people who have failed systemic chemotherapy. Regarding the treatment modalities in people with colorectal cancer liver metastases, we found no systematic reviews comparing the efficacy of TAE or TACE versus systemic chemotherapy. ⋯ The evidence regarding effectiveness of TACE versus systemic chemotherapy in people with colorectal cancer liver metastases is of very low certainty and is based on three trials. Our confidence in the results is limited due to the risk of bias, inconsistency, indirectness, and imprecision. It is very uncertain whether TACE confers benefits with regard to reduction in mortality, overall survival (time to mortality), reduction in adverse events or complications, improvement in health-related quality of life, improvement in progression-free survival, and tumour response measures (presented as the overall response rate). Data on cancer mortality, proportion of participants dying or surviving with progression of the disease, and recurrence of liver metastases are lacking. We found no trials assessing TAE versus systemic chemotherapy. More randomised clinical trials are needed to strengthen the body of evidence and provide insight into the benefits and harms of TACE or TAE in comparison with systemic chemotherapy in people with liver metastases from colorectal cancer.

Meta AnalysisAlcohol consumption and heart failure: a dose-response meta-analysis.
This is a protocol for a Cochrane Review (prototype). The objectives are as follows: Main objective To assess the effects of alcohol consumption on the progression to symptomatic (stage C) heart failure in people at risk for heart failure (stage A) or in people with pre-heart failure (stage B). ⋯ We will assess the effect of alcohol consumption on the development of heart failure with reduced ejection fraction, mildly reduced ejection fraction, and preserved ejection fraction. We also aim to evaluate the effects of alcohol consumption on the development of symptomatic (stage C) heart failure over the short, medium and long term.

Review Meta AnalysisTopical anti-inflammatory treatments for eczema: network meta-analysis.
Eczema (atopic dermatitis) is the most burdensome skin condition worldwide and cannot currently be prevented or cured. Topical anti-inflammatory treatments are used to control eczema symptoms, but there is uncertainty about the relative effectiveness and safety of different topical anti-inflammatory treatments. ⋯ Potent TCS, JAK inhibitors and tacrolimus 0.1% were consistently ranked as amongst the most effective topical anti-inflammatory treatments for eczema and PDE-4 inhibitors as amongst the least effective. Mild TCS and tapinarof 1% were ranked amongst the least effective treatments in three of five efficacy networks. TCI and crisaborole 2% were ranked most likely to cause local application-site reactions and TCS least likely. We found no evidence for increased skin thinning with short-term TCS but an increase with longer-term TCS.

Review Meta AnalysisAccuracy of routine laboratory tests to predict mortality and deterioration to severe or critical COVID-19 in people with SARS-CoV-2.
Identifying patients with COVID-19 disease who will deteriorate can be useful to assess whether they should receive intensive care, or whether they can be treated in a less intensive way or through outpatient care. In clinical care, routine laboratory markers, such as C-reactive protein, are used to assess a person's health status. ⋯ Laboratory tests, associated with hypercoagulability and hyperinflammatory response, were better at predicting severe disease and mortality in patients with SARS-CoV-2 compared to other laboratory tests. However, to safely rule out severe disease, tests should have high sensitivity (> 90%), and none of the identified laboratory tests met this criterion. In clinical practice, a more comprehensive assessment of a patient's health status is usually required by, for example, incorporating these laboratory tests into clinical prediction rules together with clinical symptoms, radiological findings, and patient's characteristics.
