Neural activation patterns in open-skilled and closed-skilled athletes during motor response tasks: insights from ERP analysis.

The present study explored behavioral outcomes and neural correlates of cognitive control abilities in open-skill sports athletes compared with closed-skill sports athletes. The participants of the study were 16 right-handed male athletes. Nine basketball players formed a group of athletes from open-skill sports, and seven outdoor track and field runners formed a comparison group for closed-skill sports.

Association of human leukocyte antigen class II alleles with epithelial cell apoptosis and extracellular matrix production in acute COVID-19.

Introduction: Pathogenic mechanisms and long-term consequences of COVID-19 require attention in studies on SARS-CoV-2. The association of the severity of COVID-19 with genetic factors, such as human leukocyte antigen (HLA) genes, remains underexplored. Our study assessed the relationships between HLA class II alleles and COVID-19 severity and blood-based indicators of systemic inflammation and organ damage, serum markers of epithelial cell apoptosis such as caspase-cleaved CK18 fragment M30 (CK18-M30) and the extracellular matrix product hyaluronic acid (HA).

Sense of country: General and specific factors covary with social identification and predict emigration plans.

Theoretical analyses of person-environment interaction describe complex models, addressing different levels of social systems, while models of the sense of community provide a base for transferring views of this interaction to the national level. This paper presents two studies that explored the structure of the sense of country and its relation to emigration plans and social identification. Study 1 involved 1,005 adults from Latvia.

Seroprevalence of diphtheria and measles antibodies and their association with demographics, self-reported immunity, and immunogenetic factors in healthcare workers in Latvia.

Latvia is among European countries with outbreaks of diphtheria and measles. Healthcare workers (HCW) are exposed to infections and can transmit them to unvaccinated patients. We assessed the seroprevalence of antibodies against diphtheria and measles and their association with demographics, self-reported immunity, the presence of the allele, and level of interferon regulatory factor 5 (IRF5) in Latvian HCW.

Expression of and genes in blood of patients with pulmonary tuberculosis.

This study aimed to detect the expression level of ORAI1 and STIM1 genes in blood of patients with bilateral pulmonary tuberculosis (TB) in comparison with the control group. Both genes encode proteins providing store-operated Ca entry (SOCE) into the cells, including immune cells, to activate transcriptional factors for producing cytokines and inflammation-restricting proteins. The study included 45 patients with confirmed TB, aged 20 to 86, and 35 volunteers, aged from 21 to 73, without active TB infection.

Intriguing findings of liver fibrosis following COVID-19.

Background: Studies on a new coronavirus disease (COVID-19) show the elevation of liver enzymes and liver fibrosis index (FIB-4) independently on pre-existing liver diseases. It points to increased liver fibrogenesis during acute COVID-19 with possible long-term consequences. This study aimed to assess liver fibrosis in COVID-19 patients by serum hyaluronic acid (HA) and FIB-4.

The Sense of Belonging to the Country: Integrative Relationships and Spatiotemporal Commitment.

The satisfaction of the need to belong reflects in the sense of being an integrative part of the group or social system. There is some lack of empirical evidence for the structure of this sense at the macro level. This study assessed a two-dimensional model of the sense of belonging to the country, which included relational and spatiotemporal components.

Epidemics among perceived impacts on Latvia before and during COVID-19: emerging threats versus stability.

Background: In the time of global challenges, perception of the ongoing change at different levels of social systems modulates individual expectations, decisions, and emotional health. A previous study in Latvia revealed that perceived threats, globalization, political power, and personal control form the latent structure of perceived impacts on the country. The present study assessed the stability of this structure, comparing a relatively favorable situation and the situation of the COVID-19 emergency in Latvia.

Burnout Clinical Subtypes Questionnaire (BCSQ-36): reliability and validity study in Latvia.

The study aimed to test the validity of the burnout subtypes hierarchic model operationalized by the 'Burnout Clinical Subtypes Questionnaire' (BCSQ-36) and its applicability in other cultures. To that aim psychometric properties, factorial and convergent validity regarding the Maslach Burnout Inventory - General Survey (MBI-GS), and correlation with demographic factors were reviewed. A voluntary internet-based approach was used on a multi-occupational sample of adult Latvians (n = 394).

Age-related trends of lesser pelvic architecture in females and males: a computed tomography pelvimetry study.

The pelvis and the spine form a system balancing human skeleton. Within this system, the pelvis adapts to age-related changes in the spine. Previous studies were predominantly focused on changes of pelvic parameters in the sagittal plane.
