RESUMEN

ObjectiveTo summarize the frequency of neurological manifestations reported in COVID-19 patients and investigate the association of these manifestations with disease severity and mortality. DesignSystematic review and meta-analysis Eligibility criteriaStudies enrolling consecutive COVID-19 patients (probable or confirmed) presenting with neurological manifestations. Data sourcesPubMed, Medline, Cochrane library, clinicaltrials.gov and EMBASE from 31st December 2019 to 15th December 2020. Data extraction and analysisTwo authors independently screened titles and abstracts retrieved by literature search. Risk of bias was examined using Joanna Briggs Institute (JBI) scale. A random-effects meta-analysis was performed, and pooled prevalence and 95% Confidence Intervals (CI) were calculated for neurological manifestations. Odds ratio (OR) and 95%CI were calculated to determine the association of neurological manifestations with disease severity and mortality. Presence of heterogeneity was assessed using I-square, meta-regression, and subgroup analyses. Statistical analyses were conducted in R version 3.6.2. ResultsOf 2,455 citations, 350 studies were included in this review, providing data on 145,634 COVID-19 patients, 89% of whom were hospitalized. Forty-one neurological manifestations (24 symptoms and 17 diagnoses) were identified. Pooled prevalence of the most common neurological symptoms included: fatigue (32%), myalgia (20%), taste impairment (21%), smell impairment (19%) and headache (13%). A low risk of bias was observed in 85% of studies; studies with higher risk of bias yielded higher prevalence estimates. Stroke was the most common neurological diagnosis (pooled prevalence-2%). In COVID-19 patients aged >60, the pooled prevalence of acute confusion/delirium was 34% and the presence of any neurological manifestations in this age group was associated with mortality (OR 1.80; 95%CI 1.11 to 2.91). ConclusionsUp to one-third of COVID-19 patients analysed in this review experienced at least one neurological manifestation. One in 50 patients experienced stroke. In those over 60, more than one-third had acute confusion/delirium; the presence of neurological manifestations in this group was associated with near doubling of mortality. Results must be interpreted keeping in view the limitations of observational studies and associated bias. Systematic review registrationPROSPERO CRD42020181867. What is already known on this topicThe frequency of neurological manifestations including fatigue, myalgia, taste and smell impairments, headache and dizziness in COVID-19 patients has been reported in a few systematic reviews and meta-analyses. However, considerable heterogeneity has been observed in terms of methodological quality of the studies, severity of the disease, mean age and hospitalization status of the patients. The evidence regarding the frequency of neurological diagnoses including stroke, encephalitis, Guillain Barre syndrome (GBS) is also limited to case reports and case series and no data exists thus far on the pooled prevalence estimates for neurological diagnoses in COVID-19 patients. What this study addsTo the best of the authors knowledge, this is the largest systematic review and meta-analysis to date (including 350 studies with data on 145,634 cases) summarizing the evidence on the frequency of the full spectrum of neurological manifestations in COVID-19 patients in the overall, young and elderly populations. For the first time, our review reports the pooled prevalence of stroke in COVID-19 patients. Risk of bias, old age and disease severity were potential determinants of the frequency and nature of neurological manifestations as well as its association with mortality. Our review also highlights the need to develop reporting standards for studies describing the frequency of clinical features. Moreover, we note that this will be the first systematic review and meta-analysis on this subject to include studies reported in all languages.

RESUMEN

IntroductionDuring the COVID-19 pandemic, there have been drastic changes in family life and programs and services that promote and protect early childhood development. Global stakeholders have raised concerns that the pandemic is putting enormous strain on parents and other caregivers, compromising capabilities and enabling environments for nurturing care of young children and therefore likely impacting childrens development. MethodologyThis rapid review takes stock of emerging research on nurturing care for young children during the COVID-19 crisis. Two databases were searched in addition to an extensive search for grey literature, drawing on 112 scholarly and scientific studies from more than 30 countries that have examined components of nurturing care during the pandemic, namely: responsive caregiving, early learning and play, and childrens safety and security. ResultsThere are some reports of unexpected positive benefits of the pandemic on families, including increased father involvement in caregiving. But more commonly, the studies findings reveal numerous issues of concern, including parental and caregiver mental health difficulties and less responsive parent-child relationships, increased screen time among children, limited opportunities for outdoor play, and fractured systems for responding to potential child neglect and maltreatment. Evidence suggests limited access and challenges in the provision of remote learning for the youngest learners, such as those in early childhood education. ConclusionThe findings can inform global stakeholders, who have advocated for increased support and funding to ensure young children and other caregivers are supported and protected during the COVID-19 pandemic. There is an urgent need for action-oriented implementation studies - those that go beyond identifying trends and begin to pinpoint "what works" to effectively promote and protect nurturing care during emergencies such as the COVID-19 pandemic. Key questionsO_ST_ABSWhat is already known?C_ST_ABSThe most fundamental promotive experiences in the early years of life to reach optimal development come from nurturing care and protection received from parents, family, and community, which have lifelong benefits including improved health and wellbeing. Health and other emergencies are detrimental to the provision of nurturing care. What are the new findings?Findings from this rapid review reveal numerous areas of concern, including families reporting mental health difficulties and less responsive parent-child relationships, increased screen time among children, limited opportunities for outdoor play, and fractured systems for responding to potential child neglect and maltreatment. As with other features of this pandemic, not all families are affected equally: financially vulnerable families are much more likely to experience negative ramifications. The pandemic is also disproportionately affecting parents and other caregivers with young children, particularly mothers, those with pre-existing mental health difficulties, and those caring for children with disabilities. What do the new findings imply?Findings highlight the need for action by governments, civil society, international and community-based organizations to improve support for families so that the pandemic does not break the provision of nurturing care and wipe out decades of progress, especially for vulnerable families and children.
