Maternal and Neonatal Characteristics for Late Foetal Death in Latvia between 2001 and 2014: Population-Based Study

2018

Introduction. Stillbirth is one of the most common adverse pregnancy outcomes worldwide. Late foetal death (LFD) rates are mostly used for international comparisons because of the large variations in stillbirth rates between countries. Objective. To examine trends in LFD (including antepartum and intrapartum) by multiple births, birth weight, and maternal age in two time periods. Methods. A retrospective cohort study was used to analyse data from the Medical Birth Register (2001–2014), divided into 2 periods of 7 years each. In total, data on 1,340 singletons were analysed. This study calculated LFD rates and rate ratios (RR). Results. The overall LFD rate showed a slight statistically sign…

Multicentric randomised study ofHelicobacter pylorieradication and pepsinogen testing for prevention of gastric cancer mortality: the GISTAR study

2017

IntroductionPopulation-based eradication ofHelicobacter pylorihas been suggested to be cost-effective and is recommended by international guidelines. However, the potential adverse effects of widespread antibiotic use that this would entail have not been sufficiently studied. An alternative way to decrease gastric cancer mortality is by non-invasive search for precancerous lesions, in particular gastric atrophy; pepsinogen tests are the best currently available alternative. The primary objective of GISTAR is to determine whetherH pylorieradication combined with pepsinogen testing reduces mortality from gastric cancer among 40–64-year-old individuals. The secondary objectives include evaluat…

“New Kids on the Block” — The Game Changers. The Role of Immune Check Point Blockade in Personalised Treatment of Prostate, Urinary Bladder and Kidne…

2021

Abstract Early detection and diagnosis of cancer followed by a personalised approach to treatment is a key and can save lives. It has been an important issue in both the medical and social fields. The search for instruments and/or diagnostics tools able to detect cancers at an early stage has led to consideration of the usage of various approaches, such as exhaled air, biomarkers in blood, urine testing as well as imaging techniques. This actual time and everything that is happening around us could be characterised as a strange and very unpredictable time. This comparison could be made not only due to the actual coronavirus situation, but also the same can be noticed in the personalised med…

Association between malocclusion and orofacial myofunctional disorders of pre‐school children in Latvia

2019

Objects Abnormal use of muscles of tongue and lips is called orofacial myofunctional disorders (OMD). In this study, we aimed to investigate the interrelation between occlusal findings and OMD in primary and mixed dentition and to find out the reasons for malocclusions, and the effect modification of these associations by the number of sources that parents used to receive the information on child oral health issues (NSI). Setting and sample population Cross-sectional study was performed in one kindergarten in Latvia (cluster sampling). The study sample comprised 141 children-mothers' pairs of pre-school children aged 4-7 years. Materials and methods Children' myofunctional situation, occlus…

Alcohol Use Disorder and Depression in Patients with Alcohol-Related Seizures

2018

Abstract Both alcohol use disorder and depression are important aspects of health in the general population and among patients with epilepsy. Depression is the most prevalent psychiatric comorbidity in epilepsy, thereby increasing morbidity as well as mortality rate. From our experience, we can see that one third of epilepsy inpatients experience seizures that are alcohol-related. There have been no studies conducted in Latvia about alcohol use disorder and depression in patients with alcohol-related seizures (ARS) and epilepsy. We recruited 108 patients with ARS, 44 of whom had comorbid epilepsy. 75% of patients in our study had depression according to the Hamilton depression scale. Higher…

Preferences of Patients for Discussing Sudden Unexpected Death in Epilepsy

2017

Abstract People with epilepsy have increased mortality rates, which is partially attributed to sudden unexpected death in epilepsy syndrome (SUDEP). Poor seizure control appears to be the strongest SUDEP risk factor. Management of epilepsy and adherence to therapy is critical to seizure control. The belief by caregivers of negative influence caused by being informed about the syndrome is the main reason SUDEP is not disclosed. There are no clear recommendations when to disclose the risk of SUDEP and how much information should be provided. We addressed the preferences of Latvian epilepsy patients for discussing SUDEP as well as awareness of the syndrome. Our study involved 55 epilepsy patie…

Mortality of Children Under Five and Prevalence of Newborn Congenital Anomalies in Relation to Macroeconomic and Socioeconomic Factors in Latvia

2012

Background. Mortality of infants and children younger than 5 years is a globally recognized and broad national welfare indicator. Scientific literature has data on the correlation of mortality indicators with macroeconomic indicators. It is important to study the associations between prevalence and mortality indicators and socioeconomic factors, since deaths from congenital anomalies account for approximately 25%–30% of all deaths in infancy. The aim of the study was to analyze the overall trend in mortality of infants and young children aged 0 to 4 years in relation to macroeconomic factors in Latvia and prevalence of congenital anomalies in newborns in relation to socioeconomic factors. M…

Alcohol-related seizures may be associated with more severe depression, alcohol dependence syndrome, and more pronounced alcohol-related problems.

2018

Severe alcohol abuse and related medical and social functioning risks, as well as clinically significant depression, are common in patients who are admitted to hospital with alcohol-related seizures (ARS) and significantly affect the quality of life of the patient. Compared with studies involving patients with alcohol dependence, no large-scale studies with the aim of finding the prevalence and severity of depression and its most commonly affected aspects for patients with ARS have been carried out in Latvia yet. The habits and frequency of alcohol use in correlation to depression and its severity are also not known. One hundred ten patients were included in the study - 60 patients with ARS…

Associations of epstein-barr virus-positive gastric adenocarcinoma with circulating mediators of inflammation and immune response

2018

Epstein-Barr virus (EBV)-positive gastric adenocarcinoma exhibits locally intense inflammation but systemic manifestations are uncertain. Our study examined whether circulating mediators of inflammation and immune response differ by tumor EBV status. From a Latvian series of 302 gastric cancer cases, we measured plasma levels of 92 immune-related proteins in the 28 patients with EBV-positive tumors and 34 patients with EBV-negative tumors. Eight markers were statistically significantly higher with tumor EBV positivity: chemokine C-C motif ligand (CCL) 20 (Odds Ratio (OR) = 3.6; p-trend = 0.001), chemokine C-X-C motif ligand 9 (OR = 3.6; p-trend = 0.003), programmed death-ligand 1 (PD-L1; OR…

Prostate Specific Antigen Dynamics and Features in Prostate Cancer

2021

Abstract Despite the common use of the prostate-specific antigen (PSA) serum level as a tumour marker in diagnosis of prostate cancer, it seems that the PSA doubling time (PSADT) and PSA velocity (PSAV) could be more useful indicators of tumour behaviour and prognosis for patients. The aim of the study was to evaluate the value of PSAV and PSADT in the diagnosis of prostate cancer and their relationship with prostate cancer histopathological characteristics. Eighty-six patients undergoing radical prostatectomy were enrolled in the study. Based on the PSA measurements the PSA dynamic values were calculated: PSADT and PSAV. In addition, clinical and histo-pathological characteristics, includi…

Efficiency of Multisensoric Therapy in Autism Spectrum Disorder Patients

2018

Abstract The aim of this study was to investigate the role of various treatment methods for children with autistic spectrum disorders (ASD). The prospective study was conducted in 2013–2015 at the Children’s University Hospital and Social Pediatric Centre of the University of Latvia. The data analysis included 72 children (2 to 5 year old) with ASD, of whom 38 had infantile autism, 16 had atypical autism, and 18 had other diffuse developmental disorder). 86.1% patients received therapy. The most common treatment was by Montessori method and special pedagogue. Other treatments were dance-movement therapy, animal, sand and one patient received spa treatments. Univariate OR analysis showed tha…

Detection of gastric atrophy by circulating pepsinogens: A comparison of three assays.

2017

Background Circulating levels of pepsinogens have been used in high gastric cancer-risk Asian and European populations to triage endoscopic evaluation for more severe pathology. There are different analytic methods with uncertain correlations. We therefore compared diagnostic performance of three commonly used pepsinogen assays to detect histologically confirmed gastric atrophy. Methods We tested plasma samples from adult patients with (n=50) and without (n=755) moderate or severe gastric corpus atrophy, as determined histologically by consensus of three expert pathologists. A single laboratory measured pepsinogens I (PgI) and II (PgII) using commercially available assays: two ELISA assays …

Risk Factors Affect Long-Term Compliance to Coumadin Treatment (Self-Reporting)

2017

Abstract Low compliance to a prescribed Coumadin treatment can result in negative health outcomes. In this study we aimed to evaluate risk factors affecting patient compliance to Coumadin. For this purpose, two study phases were performed: Phase 1: a retrospective eight-year follow-up of databases from health care services; and Phase 2: a cross-sectional study with telephone interviews. A Total Compliance Index was constructed using the number of Coumadin purchases (40%), international standardised ratio (INR) tests (40%), and average INR values (20%). Multiple models for the Total Compliance Index were constructed using socio-demographic, treatment-related, and health care utilisation vari…

Electrocardiographic Abnormalities and Mortality in Epilepsy Patients

2021

Background and Objectives: People with epilepsy (PWE) have a 2–3 times higher mortality rate than the general population. Sudden unexpected death in epilepsy (SUDEP) comprises a significant proportion of premature deaths, whereas sudden cardiac death (SCD) is among the leading causes of sudden death in the general population. Cardiac pathologies are significantly more prevalent in PWE. Whether electrocardiographic (ECG) parameters are associated with remote death in PWE has yet to be elucidated. The study objective was to assess whether interictal ECG parameters are associated with mortality in the long-term. Materials and Methods: The study involved 471 epilepsy patients who were hospitali…

Current Trends in Prostate Cancer Etiology, Pathogenesis and Diagnostics

2021

Abstract Prostate cancer (PCa) remains the second most commonly diagnosed cancer in men, with an estimated 1.1 million diagnoses worldwide in 2012, accounting for 15% of all cancers diagnosed. In many cases, successful treatment of prostate cancer is difficult due to late detection and rate of metastasis. Importantly, the tumours of many patients with prostate cancer become refractory to androgen therapy and progress to metastatic castration-resistant disease. An effective treatment course of prostate cancer patients requires predictive biomarkers in metastatic castration-resistant prostate cancer that support individual treatment. Different risk classification tools have been developed to …

Association between Anxiety, Quality of Life and Academic Performance of the Final-Year-Students in Latvia

2021

The main objective of this study was to investigate the association between final-year students’ anxiety level and quality of life (QOL) with their academic achievements. A longitudinal study was performed in regular schools and in high-rated gymnasiums at the beginning and at the end of the school year. Multiple linear regression models were built for the association between level of anxiety/QOL with academic achievements. Type of school and gender—but not the level of anxiety—were the main predictors of academic achievements of 287 adolescents (e.g., for mathematics, the effect estimates were: β = −1.71 [95% confidence interval −2.21
