Omalodes Dejean, 1833 is the largest genus of Omalodini, with approximately 63 species described in three subgenera with an exclusively Neotropical distribution. Currently there are only two described species for the Caribbean, both of the subgenus Omalodes, and among other species they are the only ones with complete apical stria on the elytra. Two new species of this subgenus: Omalodes angelo sp. nov. (Holotype male deposited in FSCA: Dominican Republic, Monte Cristi Prov.) and Omalodes kovariki sp. nov. (Holotype male deposited in USNM: Dominican Republic, Monte Cristi Prov.) are described. Both species present a complete apical stria on the elytra and a superficial sulcus or impression on the frons. The lateral pronotal punctures are more evident in O. angelo sp. nov. while in O. kovariki sp. nov. they are weaker, only slightly more evident than the ground punctures. Both species have the punctures of the propygidium somewhat sparse. However, in O. angelo sp. nov. the punctures are limited to the sides and slightly in the middle anteriorly. Omalodes kovariki sp. nov. have a wide glandular opening posterad to metacoxae, a character not registered before for the genus.

Impacts of the acid mine drainage (AMD) remediation are investigated on the largest gold mine in Latin America, located in the Dominican Republic. Geochemical analysis of suspended matter in water performed in 2022 on water bodies located downstream to the mine, namely, the Margajita River and Lake Hatillo, are compared with analyses made in 2007, before the AMD remediation. The results for the Margajita River show a strong decrease in heavy metal and metalloid concentrations in the dissolved phase for Al, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Cd, Sb, and Pb (between 89.

Electrical bioimpedance is based on the opposition exerted by body tissues to the passage of an electrical current. This characteristic allows the assessment of the individual's body composition, nutritional status, and hydration status. Electrical bioimpedance can be used to estimate body composition, health-related markers, general health status, diagnosis and prognostic of diseases, evaluation of treatment progress, and others.

Little is known about the epidemiology of leptospirosis in the Dominican Republic, the second most populous country in the Caribbean. We report on findings from a multi-stage household survey across two regions in the country that reveals a previously under-estimated burden of human Leptospira infection. Our findings, based on the reference-standard microscopic agglutination test, indicate a complex picture of serogroup diversity, spatial heterogeneity in infection and risk, and a marked discrepancy between reported cases and serologically estimated infections.

Background: Tuberculosis vaccine trials using disease as the primary endpoint are large, time consuming, and expensive. An earlier immunological measure of the protection against disease would accelerate tuberculosis vaccine development. We aimed to assess whether the effectiveness of the Bacillus Calmette-Guérin (BCG) vaccine for prevention of Mycobacterium tuberculosis infection was consistent with that for prevention of tuberculosis disease.

The correct analysis of medical images requires the medical knowledge and expertise of radiologists to understand, clarify, and explain complex patterns and diagnose diseases. After analyzing, radiologists write detailed and well-structured reports that contribute to the precise and timely diagnosis of patients. However, manually writing reports is often expensive and time-consuming, and it is difficult for radiologists to analyze medical images, particularly images with multiple views and perceptions.
