RESUMEN
This systematic review evaluates the evidence for accuracy of automated analyzers that estimate cerebrospinal fluid (CSF) white blood cell counts (WBC) compared to manual microscopy. Inclusion criteria of original research articles included human subjects, English language, and manual microscopy comparator. PUBMED, EMBASE and Cochrane Review databases were searched through 2019 and QUADAS-2 Tool was used for assessment of bias. Data were pooled and analyzed by comparison method, using random effects estimation. Among 652 titles, 554 abstracts screened, 104 full-text review, 111 comparisons from 41 studies were included. Pooled estimates of sensitivity and specificity (n = 7) were 95% (95%-CI 93%-97%) and 84% (95%-CI: 64%-96%), respectively. Pooled R2 estimates (n = 29) were 0.95 (95%-CI: 0.95-0.96); Pooled spearman rho correlation (n = 27) estimates were 0.95 (95% CI 0.95-0.96). Among those comparisons using Bland-Altman analysis (n = 11) pooled mean difference was estimated at 0.98 (95% CI-0.54-2.5). Among comparisons using Passing-Bablok regressions (n = 14) the pooled slope was estimated to be 1.05 (95% CI 1.03-1.07). Q tests of homogeneity were all significant with the exception of the Bland-Altman comparisons (I2 10%, p value 0.35). There is good overall accuracy for CSF WBC by automated hematologic analyzers. These findings are limited by the small sample sizes and inconsistent validation methodology in the reviewed studies.
RESUMEN
Description The COVID-19 pandemic has intensified the existing health and social disparities that affect minority groups in the United States (US), including the Latinx community. This situation has been reflected in many aspects of health, including increased morbi-mortality and reduced adherence to medical and scientific recommendations. Limited access to health care, financial challenges, migrant status, and health literacy, or lack thereof, have all hampered the Latinx community's ability to seek aid quickly and to be tested or treated effectively for this disease. This pandemic has shown that the Latinx community's socioeconomic status correlates with greater mortality rates when compared to other ethnic groups, which runs counter to historical norms. Furthermore, morbi-mortality in Latinx people has been disproportionately greater. Beyond the systematic barriers that the Latinx community has had to face to access care during the pandemic, there were also perception barriers that increased the gap and further complicated the situation. Latinxs were more likely to be exposed due to a decreased compliance with physical distancing. When it was suggested to avoid crowds, many people started using delivery services; however, many Latinxs found the cost and requirements of reliable internet to be a barrier to using these services. Currently, COVID-19 vaccines are broadly available in the US but there has been skepticism from marginalized communities, including the Latinx population, about getting vaccinated. Integrating this population into a welcoming healthcare system, safeguarding their immigration and work status, providing more accessible vaccination locations, and promoting health equality and education would all assist to lessen the impact of this illness on the Latinx community.
