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).

Review Meta AnalysisInterventions for BK virus infection in kidney transplant recipients.
BK virus-associated nephropathy (BKVAN), caused by infection with or reactivation of BK virus, remains a challenge in kidney transplantation. Screening is recommended for all kidney transplant recipients. For those with clinically significant infection, reduction of immunosuppression is the cornerstone of management. There is no specific antiviral or immunomodulatory therapy sufficiently effective for routine use. ⋯ Intense monitoring early after transplantation for BK viruria and BK viraemia is effective in improving BK virus infection outcomes as it helps with early detection of the infection and allows for a timely reduction in immunosuppression reduction. There is insufficient evidence to support any other intervention for BK virus infection in kidney transplant recipients.

Review Meta AnalysisPatient navigator programmes for children and adolescents with chronic diseases.
Despite a substantial global improvement in infant and child mortality from communicable diseases since the early 1990s there is now a growing burden of chronic disease in children and adolescents worldwide, mimicking the trend seen in the adult population. Chronic diseases in children and adolescents can affect all aspects of their well-being and function with these burdens and their health-related consequences often carried into adulthood. Up to one third of disability-adjusted life years for children and adolescents globally are a result of chronic disease. This has profound implications for the broader family unit, communities, and health systems in which these children and young people reside. Models of chronic care delivery for children and adolescents with chronic disease have traditionally been adapted from adult models. There is a growing recognition that children and adolescents with chronic diseases have a unique set of healthcare needs. Their needs extend beyond disease education and management appropriate to the developmental stage of the child, to encompass psychological well-being for the entire family and a holistic care approach focusing on the social determinants of health. It is for this reason that patient navigators have been proposed as a potential intervention to help fulfil this critical healthcare gap. Patient navigators are trained medical or non-medical personnel (e.g. lay health workers, community health workers, nurses, or people with lived experience) who provide guidance for the patients (and their primary caregivers) as they move through complex (and often bewildering) medical and social systems. The navigator may deliver education, help to co-ordinate patient care, be an advocate for the patient (and their primary caregivers), or combinations of these. Patient navigators can assist people with a chronic illness (especially those who are vulnerable or from a marginalised population, or both) to better understand their diagnoses, treatment options, and available resources. As there is considerable variation in the purpose, design, and target population of patient navigator programmes, there is a need to systematically review and summarise the existing literature on the effectiveness of navigator programmes in children and young adults with chronic disease. ⋯ There is insufficient evidence at present to support the use of patient navigator programmes for children and adolescents with chronic diseases. The current evidence is based on limited data with very low-certainty evidence. Further studies are likely to significantly change these results.
