Review Meta AnalysisBlood pressure targets for hypertension in people with chronic renal disease.
Chronic kidney disease (CKD) is an independent risk factor for cardiovascular disease, development of end-stage renal disease, and all-cause mortality. It affects around 10% of the population worldwide. The prevalence of hypertension in people with CKD ranges from 22% in stage 1 to 80% in stage 4. Elevated arterial blood pressure is one of the major independent risk factors for adverse cardiovascular events. Thereby, reducing blood pressure to below standard targets may be beneficial but could also increase the risk of adverse events. The optimal blood pressure target in people with hypertension and CKD remains unknown. ⋯ Compared to a standard blood pressure target, lower blood pressure targets probably result in little to no difference in total mortality, total serious adverse events, and total cardiovascular events, and may result in little to no difference in total cardiovascular mortality or in the progression to end-stage renal disease in people with hypertension and CKD. However, the evidence underpinning these conclusions has several limitations. All studies were open design, blood pressure measurement was performed at a medical office, and there was scant information about adverse events. Future research should include high-quality adverse event data, report results for people with different levels of proteinuria, and consider out-of-office blood pressure monitoring. Several studies are ongoing, and may provide new evidence for this topic in the near future.

Review Meta AnalysisLaboratory-based molecular test alternatives to RT-PCR for the diagnosis of SARS-CoV-2 infection.
Diagnosing people with a SARS-CoV-2 infection played a critical role in managing the COVID-19 pandemic and remains a priority for the transition to long-term management of COVID-19. Initial shortages of extraction and reverse transcription polymerase chain reaction (RT-PCR) reagents impaired the desired upscaling of testing in many countries, which led to the search for alternatives to RNA extraction/purification and RT-PCR testing. Reference standard methods for diagnosing the presence of SARS-CoV-2 infection rely primarily on real-time reverse transcription-polymerase chain reaction (RT-PCR). Alternatives to RT-PCR could, if sufficiently accurate, have a positive impact by expanding the range of diagnostic tools available for the timely identification of people infected by SARS-CoV-2, access to testing and the use of resources. ⋯ Alternative laboratory-based molecular tests aim to enhance testing capacity in different ways, such as reducing the time, steps and resources needed to obtain valid results. Several index test technologies with these potential advantages have not been evaluated or have been assessed by only a few studies of limited methodological quality, so the performance of these kits was undetermined. Only two index test categories with enough evaluations for meta-analysis fulfil the WHO set of acceptable accuracy standards for SARS-CoV-2 nucleic acid tests: RT-PCR assays designed to omit/adapt RNA extraction/purification and TMA assays. These assays might prove to be suitable alternatives to RT-PCR for identifying people infected by SARS-CoV-2, especially when the alternative would be not having access to testing. However, these findings need to be interpreted and used with caution because of several limitations in the evidence, including reliance on retrospective samples without information about the symptom status of participants and the timing of assessment. No extrapolation of found accuracy data for these two alternatives to any test brands using the same techniques can be made as, for both groups, one test brand with high accuracy was overrepresented with 21/26 and 12/14 included studies, respectively. Although we used a comprehensive search and had broad eligibility criteria to include a wide range of tests that could be alternatives to RT-PCR methods, further research is needed to assess the performance of alternative COVID-19 tests and their role in pandemic management.

Review Meta AnalysisNasal continuous positive airway pressure immediately after extubation for preventing morbidity in preterm infants.
Preterm infants who are extubated following a period of invasive ventilation via an endotracheal tube are at risk of developing respiratory failure, leading to reintubation. This may be due to apnoea, respiratory acidosis, or hypoxia. Historically, preterm infants were extubated to head box oxygen or low-flow nasal cannulae. Support with non-invasive pressure might help improve rates of successful extubation in preterm infants by stabilising the upper airway, improving lung function, and reducing apnoea. This is an update of a review first published in 1997 and last updated in 2003. ⋯ NCPAP may be more effective than no CPAP in preventing extubation failure in preterm infants if applied immediately after extubation from invasive mechanical ventilation. We are uncertain whether it can reduce the risk of reintubation or bronchopulmonary dysplasia. We have no information on long-term neurodevelopmental outcomes. Although there is only low-certainty evidence for the effectiveness of NCPAP immediately after extubation in preterm infants, we consider there is no need for further research on this intervention, which has become standard practice.

The experiences and perspectives of abortion seekers who travel for care: a qualitative evidence synthesis.
This is a protocol for a Cochrane Review (qualitative). The objectives are as follows: This QES aims to address the following question: What are the lived experiences and perceptions of abortion seekers (i.e. pregnant women, transgender men, and non-binary people of any gender) traveling to obtain care? The review objectives are to: synthesize the qualitative evidence to address the review question; identify factors that influence abortion travel experiences and perspectives, which may include the specific abortion regulatory and care delivery context (e.g. legal restrictions, unavailability) and abortion seekers' personal circumstances (e.g. age, race/ethnicity, gender, partnership status, gestational duration, social/family support, income/wealth).
