The Ancestry of Eastern Paraguay: A Typical South American Profile with a Unique Pattern of Admixture. Genes (Basel) 2021; 12:1788.

Abstract
Immigrants from diverse origins have arrived in Paraguay and produced important demographic changes in a territory initially inhabited by indigenous Guarani. Few studies have been performed to estimate the proportion of Native ancestry that is still preserved in Paraguay and the role of females and males in admixture processes. Therefore, 548 individuals from eastern Paraguay were genotyped for three marker sets: mtDNA, Y-SNPs and autosomal AIM-InDels. A genetic homogeneity was found between departments for each set of markers, supported by the demographic data collected, which showed that only 43% of the individuals have the same birthplace as their parents. The results show a sex-biased intermarriage, with higher maternal than paternal Native American ancestry. Within the native mtDNA lineages in Paraguay (87.2% of the total), most haplogroups have a broad distribution across the subcontinent, and only few are concentrated around the Paraná River basin. The frequency distribution of the European paternal lineages in Paraguay (92.2% of the total) showed a major contribution from the Iberian region. In addition to the remaining legacy of the colonial period, the joint analysis of the different types of markers included in this study revealed the impact of post-war migrations on the current genetic background of Paraguay.

Ribeiro HG, Dantas-Komatsu RCS, Medeiros JFP, Carvalho MCDC, Soares VDL, Reis BZ, Luchessi AD, Silbiger VN. Previous vitamin D status and total cholesterol are associated with SARS-CoV-2 infection. Clin Chim Acta 2021; 522:8-13. [PMID: 34364853 PMCID: PMC8340549 DOI: 10.1016/j.cca.2021.08.003] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2021] [Revised: 07/20/2021] [Accepted: 08/03/2021] [Indexed: 12/18/2022]
Abstract
BACKGROUND The relationship of vitamin D status and other biochemical parameters with the risk of SARS-CoV-2 infection remains inconclusive, especially in regions with high solar incidence. Therefore, we aimed to associate the 25-hydroxyvitamin D (25(OH)D) concentrations and lipid profile prior to the SARS-CoV-2 tests in a population from a sunny region in Brazil (5 degrees S, 35 degrees W). METHODS This retrospective cohort study enrolled 1634 patients tested for SARS-CoV-2 of a private medical laboratory with 25(OH)D concentration and lipid profile measured ≥ 7 days before the date of the first SARS-CoV-2 RT-PCR test and were categorized according to 25(OH)D sufficiency (≥30 ng/mL) or insufficiency (<30 ng/mL). Multiple logistic regression analyses were performed to assess risk factors associated with positive tests for SARS-CoV-2. RESULTS Average serum 25(OH)D was 33.6 ng/mL. Vitamin D deficiency (<20 ng/mL) was only found in 2.6% of the participants. Multivariate analysis demonstrated that patients > 49 y with insufficient 25(OH)D (<30 ng/mL) presented increased odds to test positive for SARS-CoV-2 (OR: 2.02, 95 %CI: 1.15 to 3.55, P = 0.015). The same is observed among those with total cholesterol > 190 mg/dL (OR: 1.90, 95 %CI: 1.10 to 3.28, P = 0.020). CONCLUSIONS Previous insufficient 25(OH)D (<30 ng/mL) concentration and high total cholesterol were associated with SARS-CoV-2 infection among adults > 48 y in the study population. Further studies should be conducted to confirm whether measurement of 25(OH)D and lipid profile could be useful to identify patients who are more susceptible to COVID-19.

Phylogeographic review of Y chromosome haplogroups in Europe. Int J Legal Med 2021; 135:1675-1684.

Abstract
The Y chromosome has been widely explored for the study of human migrations. Due to its paternal inheritance, the Y chromosome polymorphisms are helpful tools for understanding the geographical distribution of populations all over the world and for inferring their origin, which is really useful in forensics. The remarkable historical context of Europe, with numerous migrations and invasions, has turned this continent into a melting pot. For this reason, it is interesting to study the Y chromosome variability and how it has contributed to improving our knowledge of the distribution and development of European male genetic pool as it is today. The analysis of Y lineages in Europe shows the predominance of four haplogroups, R1b-M269, I1-M253, I2-M438 and R1a-M420. However, other haplogroups have been identified which, although less frequent, provide significant evidence about the paternal origin of the populations. In addition, the study of the Y chromosome in Europe is a valuable tool for revealing the genetic trace of the different European colonizations, mainly in several American countries, where the European ancestry is mostly detected by the presence of the R1b-M269 haplogroup. Therefore, the objective of this review is to compile the studies of the Y chromosome haplogroups in current European populations, in order to provide an outline of these haplogroups which facilitate their use in forensic studies.
