Review Meta AnalysisNoise or sound management in the neonatal intensive care unit for preterm or very low birth weight infants.
Infants in the neonatal intensive care unit (NICU) are subjected to different types of stress, including sounds of high intensity. The sound levels in NICUs often exceed the maximum acceptable level recommended by the American Academy of Pediatrics, which is 45 decibels (dB). Hearing impairment is diagnosed in 2% to 10% of preterm infants compared to only 0.1% of the general paediatric population. Bringing sound levels under 45 dB can be achieved by lowering the sound levels in an entire unit; by treating the infant in a section of a NICU, in a 'private' room, or in incubators in which the sound levels are controlled; or by reducing sound levels at the individual level using earmuffs or earplugs. By lowering sound levels, the resulting stress can be diminished, thereby promoting growth and reducing adverse neonatal outcomes. This review is an update of one originally published in 2015 and first updated in 2020. ⋯ No studies evaluated interventions to reduce sound levels below 45 dB across the whole neonatal unit or in a room within it. We found only one study that evaluated the benefits of sound reduction in the neonatal intensive care unit for hearing protection in preterm infants. The study compared the use of silicone earplugs versus no earplugs in newborns of very low birth weight (less than 1500 g). Considering the very small sample size, imprecise results, and high risk of attrition bias, the evidence based on this research is very uncertain and no conclusions can be drawn. As there is a lack of evidence to inform healthcare or policy decisions, large, well designed, well conducted, and fully reported RCTs that analyse different aspects of noise reduction in NICUs are needed. They should report both short- and long-term outcomes.

ReviewComprehensive care programmes for children with medical complexity.
Children with medical complexity (CMC) represent a small, but growing, proportion of all children. Regardless of their underlying diagnosis, by definition, all CMC have similar functional limitations and high healthcare needs. It has been suggested that improving aspects of healthcare delivery for CMC improves health- and quality of life-related outcomes for children and their families and reduces healthcare-related expenditure. As a result, dedicated comprehensive care programmes have been established at many hospitals to meet the needs of CMC; however, it is unclear if such programmes are effective. ⋯ The findings of this review should be treated with caution due to the limited amount and quality of the published research that was available to be included. Overall, the certainty of the evidence for the effectiveness of comprehensive care for CMC ranged from low to moderate across outcomes and there is currently insufficient evidence on which to draw strong conclusions. There is a need for more high-quality randomised trials with consistency of the target population and intervention components, methods of reporting outcomes, and follow-up periods, as well as full cost analyses, taking into account both costs to the family and costs to the healthcare system.

ReviewApproaches for delivery of refractive and optical care services in community and primary care settings.
Uncorrected refractive error is a leading cause of vision impairment which, in most cases, can be managed with the appropriate spectacle correction. In 2021, the World Health Assembly endorsed a global target of a 40-percentage-point increase in effective coverage of refractive error by 2030. To achieve this global target, equitable access to refractive and optical services within community and primary care settings needs to be strengthened. This review will inform the development of technical guidance to support improvements in the testing and correction of refractive error among World Health Organization (WHO) member states. ⋯ The protocol of this scoping review was published in the Open Source Framework.

ReviewNon-pharmacological interventions for improving language and communication in people with primary progressive aphasia.
Primary progressive aphasia (PPA) accounts for approximately 43% of frontotemporal dementias and is mainly characterised by a progressive impairment of speech and communication abilities. Three clinical variants have been identified: (a) non-fluent/agrammatic, (b) semantic, and (c) logopenic/phonological PPA variants. There is currently no curative treatment for PPA, and the disease progresses inexorably over time, with devastating effects on speech and communication ability, functional status, and quality of life. Several non-pharmacological interventions that may improve symptoms (e.g. different forms of language training and non-invasive brain stimulation) have been investigated in people with PPA. ⋯ There is currently no high-certainty evidence to inform clinical decision-making regarding non-pharmacological treatment selection for people with PPA. Preliminary evidence suggests that the combination of active tDCS with specific language therapy may improve impaired word retrieval for specifically trained items beyond the effects of behavioural treatment alone. However, more research is needed, including high-quality RCTs with detailed descriptions of participants and methods, and consideration of outcomes such as quality of life, depressive symptoms, and overall cognitive functioning. Moreover, studies assessing optimal treatments (i.e. behavioural interventions, brain stimulation interventions, and their combinations) for individual patients and PPA subtypes are needed. We were not able to conduct the planned (network) meta-analyses due to missing data that could not be obtained from most of the authors, a general lack of RCTs in the field, and heterogeneous interventions in eligible trials. Journals should implement a mandatory data-sharing requirement to assure transparency and accessibility of data from clinical trials.

Review Meta AnalysisManual therapy and exercise for lateral elbow pain.
Manual therapy and prescribed exercises are often provided together or separately in contemporary clinical practice to treat people with lateral elbow pain. ⋯ Low-certainty evidence from a single trial in people with lateral elbow pain indicates that, compared with placebo, manual therapy may provide a clinically worthwhile benefit in terms of pain and disability at the end of treatment, although the 95% confidence interval also includes both an important improvement and no improvement, and the longer-term outcomes are unknown. Low-certainty evidence from 12 trials indicates that manual therapy and exercise may slightly reduce pain and disability at the end of treatment, but this may not be clinically worthwhile and these benefits are not sustained. While pain after treatment was an adverse event from manual therapy, the number of events was too small to be certain.
