Symptoms of Anxiety and Depression in Adolescents During the COVID-19 Pandemic
2022
Pētījuma mērķis bija izpētīt jūtas un darbības, kuras liecina par trauksmes pastāvēšanu un depresijas simptomus pusaudžiem mācoties attālināti un mācoties klātienē. Datu ievākšanai tika izmantota Reinolda un Ričmonda uzlabotā bērnu trauksmes skala (Vasiļenko, 2005). Depresijas simptomu noteikšanai tika piedāvāta Bērnu depresijas aptauja “Manas domas un izjūtas pēdējās divās nedēļās” (Kovacs, 1981, Miezītis un Kalnins, 1995). Šī maģistra darba ietvaros iekļauti papildjautājumi, kas saistīti ar Covid-19 pandēmiju. Pētījumā tika izmantots longitudinālais dizains. Pētījumā piedalījās 2020. /2021. m.g. 2. semestrī 288 respondenti, 7. un 8. klašu skolēni vecumā no 13 līdz 15 gadiem, un 2021. /202…

The impact of lactic acid bacteria with antimicrobial properties on biodegradation of polycyclic aromatic hydrocarbons and biogenic amines in cold sm…
2017
The influence of surface treatment with lactic acid bacteria (LAB), previously cultivated in an alternative substrate, on the formation of polycyclic aromatic hydrocarbons (PAHs) and biogenic amines (BAs) in cold smoked pork meat sausages was investigated. Moreover, sausages treatment with LAB after the smoking on PAHs content changes was evaluated. Additionally, the inhibitory effects of LAB metabolites on food spoilage bacteria was determined using the agar well diffusion assay method. The metabolites of Pediococcus acidilactici KTU05-7, Pediococcus pentosaceus KTU05-9 and Lactobacillus sakei KTU05-6 strains showed good inhibitory properties against tested pathogenic and food spoilage bac…
Randomized, Double-Blind, Clinically Controlled Trial of Intranasal Calcitonin Treatment in Patients with Hip Fracture
2002
The objective of this study was to evaluate the short-term outcome of intranasal calcitonin treatment of elderly hip fracture patients on pain, bone loss, functional recovery, and length of hospital stay. In addition, we wanted to compare the effect of calcitonin with placebo on fusion of hip fractures treated with internal fixation using a screw or a nail. In a randomized, double-blind, clinically controlled trial, 260 independently living patients (aged 65 years or older) with acute hip fracture were randomly assigned to intranasal calcitonin 200 IU daily for 3 months or matching placebo nasal spray. Analyses were completed on an intention-to-treat basis. Three months after the operation,…

L’amiante est classé en tant que substance cancérogène avérée pour l’humain (groupe 1 du Centre International de Recherche sur la Cancer (CIRC)) depuis les années 70 pour le poumon et la plèvre. La monographie sur l’amiante actualisée en 2012 indique que des preuves suffisantes sont maintenant disponibles pour démontrer le lien entre l’exposition à l’amiante et les cancers du larynx et de l'ovaire. Dans cette monographie, les cancers du pharynx, de l’estomac et les cancers colorectaux sont considérés comme possiblement liés à une exposition à l’amiante, mais avec un niveau de preuve limité.A ce jour, seuls les cancers broncho-pulmonaires provoqués par l'inhalation de poussières d'amiante [t…
Fuzzy subgroup mining for gene associations
2004
When studying the therapeutic efficacy of potential new drugs, it would be much more efficient to use predictors in order to assess their toxicity before going into clinical trials. One promising line of research has focused on the discovery of sets of candidate gene profiles to be used as toxicity indicators in future drug development. In particular genomic microarrays may be used to analyze the causality relationship between the administration of the drugs and the so-called gene expression, a parameter typically used by biologists to measure its influence at gene level. This kind of experiments involves a high throughput analysis of noisy and particularly unreliable data, which makes the …

HERS study disturbs hormonal replacement therapy
2000
Cardiovascular protection of hormonal replacement therapy was considered a fact. The effects of estrogens on lipid levels and vascular health gave biological support to estrogen cardioprotection. The recently published HERS study showing no protective effects of estrogen and progesterone replacement therapy on the risk of myocardial infarction or coronary deaths is provoking perplexity. These surprising results may have several causes such as the use of progesterone, the associated use of cardioprotective agents or the short observation period. However, the study results scope is rectricted to secondary prevention. These cannot be extrapolated to frequent conditions of postmenopausal women …
The cholesterol paradox in atrial fibrillation: results from the LIPIDOGRAM 2015 study
2020
Abstract Background High blood lipid levels are known risk factors for atherosclerotic cardiovascular events, but associations between lipid levels and atrial fibrillation (AF) are unclear. Some previous studies have suggested an inverse association between lipid levels and AF referred to as the “cholesterol paradox”. Purpose To examine the prevalence of AF by differing lipid levels in a large population-based study of almost 14,000 adults in Poland. Methods The LIPIDOGRAM 2015 study is a cross-sectional study of adults aged 18 years and older recruited in Poland in 2015/2016 by 438 family physicians. Poisson regression models with robust variance were used to estimate prevalence ratios (PR…
