Varicella presents a public health challenge in Guatemala, with limited evidence regarding its impact; vaccine is currently absent from the national immunization program. Generating local data on the economic and health burden can support immunization policies. This study describes the use of hospital resources, costs of care, clinical and demographic characteristics, and complications in children with varicella.

Article Synopsis
  • The study examined 33 severe COVID-19 patients who underwent a novel hemoperfusion therapy using the Seraph100 filter, aiming to reduce viral RNA levels and markers of inflammation.
  • Results showed that while the initial levels of SARS-CoV-2 RNA were generally low and did not significantly change post-treatment, five inflammatory protein analytes exhibited notable decreases, indicating some therapeutic effect on inflammation and endothelial damage.
  • The conclusion highlighted that Seraph 100 did not effectively lower viral RNA levels, but it did successfully reduce several inflammatory markers in the blood of these patients.

Hormone-dependent cancers (HDCs) share several risk factors, suggesting a common aetiology. Using data from genome-wide association studies, we showed spatial clustering of risk variants across four HDCs (breast, endometrial, ovarian and prostate cancers), contrasting with genetically uncorrelated traits. We identified 44 multi-HDC risk regions across the genome, defined as overlapping risk regions for at least two HDCs: two regions contained risk variants for all four HDCs, 13 for three HDCs and 28 for two HDCs.

Puerto Ricans are underrepresented in genetic research. This underrepresentation denies Puerto Ricans the benefit from therapeutic developments that could mitigate health disparities arising from conditions for which genetically-derived treatments exist. The Puerto Rican diaspora, especially post-2017 due to economic and environmental crises, has expanded within the USA.
