Review Meta AnalysisHigher blood pressure targets for hypertension in older adults.
This is an update of the original Cochrane review, published in 2017. Eight out of 10 major antihypertensive trials in adults, 65 years of age or older, attempted to achieve a target systolic blood pressure (BP) of < 160 mmHg. Collectively, these trials demonstrated cardiovascular benefit for treatment, compared to no treatment, for older adults with BP > 160 mmHg. However, an even lower BP target of < 140 mmHg is commonly applied to all age groups. Yet the risk and benefit of antihypertensive therapy can be expected to vary across populations, and some observational evidence suggests that older adults who are frail might have better health outcomes with less aggressive BP lowering. Current clinical practice guidelines are inconsistent in target BP recommendations for older adults, with systolic BP targets ranging from < 130 mmHg to < 150 mmHg. The 2017 review did not find compelling evidence of a reduction in any of the primary outcomes, including all-cause mortality, stroke, or total serious cardiovascular adverse events, comparing a lower BP target to a higher BP target in older adults with hypertension. It is important to update this review to explore if new evidence exists to determine whether older adults might do just as well, better, or worse with less aggressive pharmacotherapy for hypertension. ⋯ When comparing a higher BP target, in the range of < 150 to 160/95 to 105 mmHg, to a lower BP target of 140/90 or lower, over two to four years of follow-up, there is high-certainty evidence that the lower BP target reduces stroke, and moderate-certainty evidence that the lower BP target likely reduces serious cardiovascular events. The effect on all-cause mortality is unclear (low-certainty evidence), and the lower BP target likely does not increase withdrawals due to adverse effects (moderate-certainty evidence). Although additional research is warranted in those who are 80 years of age and older, and those who are frail (in whom risks and benefits may differ), conventional BP targets may be appropriate for the majority of older adults.

GALAD, or des-gamma-carboxy prothrombin compared with alpha-foetoprotein for the diagnosis of hepatocellular carcinoma in people with chronic liver disease.
This is a protocol for a Cochrane Review (diagnostic). The objectives are as follows: To estimate the diagnostic accuracy of des-gamma-carboxy prothrombin, GALAD (Gender, Age, Lens culinaris agglutinin-reactive AFP, AFP and DCP), and alpha-foetoprotein for the diagnosis of hepatocellular carcinoma of any size, and at any stage, in adults with chronic liver disease, in either a surveillance programme or a clinical setting. We acknowledge the possibility that theoretically, the accuracy of the tests in a surveillance programme may differ from that in a clinical setting due to variation in inclusion criteria and the prevalence of the target condition. ⋯ To compare the diagnostic accuracy of des-gamma-carboxy prothrombin (DCP) alone or GALAD alone versus alpha-foetoprotein (AFP), for the diagnosis of hepatocellular carcinoma (HCC) of any size, at any stage; in adults with chronic liver disease, either in a surveillance programme or a clinical setting. Secondary objectives To estimate the diagnostic accuracy of DCP or GALAD versus AFP, for resectable HCC in people with chronic liver disease, in a surveillance programme and a clinical setting. To investigate the following predefined sources of heterogeneity for each of the index tests: study design (case-control studies compared to cross-sectional studies); inclusion of participants without cirrhosis (studies including more than 10% of participants without cirrhosis compared to studies including less than 10% of participants without cirrhosis); study location (population differences): studies conducted in North and South America and Europe compared to Asia and Africa; prevalence of the target condition (studies with hepatocellular carcinoma prevalence more than 10% compared to studies with hepatocellular carcinoma prevalence less than 10%); participant selection (participants recruited from planned surveillance programmes compared to clinical cohorts); different reference standards (histology of the explanted liver compared to liver biopsy compared to another reference standard); different aetiology: studies including at least 90% of participants with chronic viral hepatitis compared to studies including less than 90% of participants with chronic viral hepatitis.

Review Meta AnalysisThe effect of sample site and collection procedure on identification of SARS-CoV-2 infection.
Sample collection is a key driver of accuracy in the diagnosis of SARS-CoV-2 infection. Viral load may vary at different anatomical sampling sites and accuracy may be compromised by difficulties obtaining specimens and the expertise of the person taking the sample. It is important to optimise sampling accuracy within cost, safety and accessibility constraints. ⋯ When used with RT-PCR, there is no evidence for a difference in sensitivity of self-collected gargle or deep-throat saliva samples compared to nasopharyngeal samples collected by healthcare workers when used with RT-PCR. Use of these alternative, self-collected sample types has the potential to reduce cost and discomfort and improve the safety of sampling by reducing risk of transmission from aerosol spread which occurs as a result of coughing and gagging during the nasopharyngeal or oropharyngeal sample collection procedure. This may, in turn, improve access to and uptake of testing. Other types of saliva, nasal, oral and oropharyngeal samples are, on average, less sensitive compared to healthcare worker-collected nasopharyngeal samples, and it is unlikely that sensitivities of this magnitude would be acceptable for confirmation of SARS-CoV-2 infection with RT-PCR. When used with Ag-RDTs, there is no evidence of a difference in sensitivity between nasal samples and healthcare worker-collected nasopharyngeal samples for detecting SARS-CoV-2. The implications of this for self-testing are unclear as evaluations did not report whether nasal samples were self-collected or collected by healthcare workers. Further research is needed in asymptomatic individuals, children and in Ag-RDTs, and to investigate the effect of operator expertise on accuracy. Quality assessment of the evidence base underpinning these conclusions was restricted by poor reporting. There is a need for further high-quality studies, adhering to reporting standards for test accuracy studies.

Dose reduction and discontinuation of biologic and targeted synthetic disease-modifying anti-rheumatic drugs (DMARDs) for people with psoriatic arthritis in remission or low disease activity.
This is a protocol for a Cochrane Review (intervention). The objectives are as follows: To determine the benefits and harms of dose reduction or discontinuation of biologic disease-modifying anti-rheumatic drugs or targeted synthetic disease-modifying anti-rheumatic drugs in adults with psoriatic arthritis who are in remission or a low disease activity state.
