ABO and Rh blood groups, demographics, and comorbidities in COVID-19 related deaths: A retrospective study in Split-Dalmatia County, Croatia.

Background: Blood group phenotypes have been associated with COVID-19 susceptibility and severity. This study aimed to examine ABO/Rh blood group distribution in COVID-19-related deaths considering demographics and pathological conditions.

Methods: We conducted a retrospective study at the University Hospital Center Split, Croatia, that included 245 COVID-19 positive individuals that died from April 8, 2020, to January 25, 2021.

Sex estimation standards for medieval and contemporary Croats.

Aim: To develop discriminant functions for sex estimation on medieval Croatian population and test their application on contemporary Croatian population.

Methods: From a total of 519 skeletons, we chose 84 adult excellently preserved skeletons free of antemortem or postmortem changes and took all standard measurements. Sex was estimated/determined using standard anthropological procedures and ancient DNA (amelogenin analysis) where pelvis was insufficiently preserved or where sex morphological indicators were not consistent.

Functional Changes of P300 Values among Young Football Players as a Measure of a Cognitive Function.

Numerous studies have shown that evaluation of evoked potentials (EP) is an excellent estimation tool for a cognitive function. During daily practices footballers are exposed to headers that can leave mild head traumas. In this study, young footballers were examined, while the control group included their coevals who don't practice contact sports.

Carcinoembryonic antigen immunoreactivity patterns in colorectal cancer: Correlation with morphologic parameters.

The expression of carcinoembryonic antigen (CEA) was analyzed immunohistochemically in 100 colorectal cancer specimens. The tumors were divided into three groups, according to the predominant staining pattern which was either apical, cytoplasmic or stromal. CEA localization was apical in 26 cases, cytoplasmic in 48 and stromal in 26 cases.
