RESUMO
AIM: To investigate the prevalence of tooth agenesis and associated dental anomalies in Latvian adolescent dental patients and compare it to other European countries. DESIGN: Cross-sectional study of 2692 11-to-14-year-old patients (39.9% males and 60.1% females) attending Riga Stradins University Institute of Stomatology with panoramic radiographs taken between August 2020 and September 2021. Patients with any genetic syndromes were excluded. Data on tooth agenesis (excluding third molars) and other dental anomalies were recorded. RESULTS: The prevalence of tooth agenesis in Latvian adolescent dental patients was 9.3% with no statistically significant difference between genders (χ2 test, p = 0.472). The most commonly missing teeth were mandibular second premolars, followed by upper lateral incisors and upper second premolars. There was a statistically significant association with the presence of other dental anomalies in tooth agenesis patients (p < 0.001). CONCLUSIONS: This study found that the prevalence of non-syndromic tooth agenesis in Latvian adolescent dental patients was 9.3% with no statistically significant differences between the genders. Patients with tooth agenesis have a statistically significant possibility of the presence of other dental anomalies (p < 0.001).

BACKGROUND: High-risk human papillomavirus (HR-HPV) is a known cause of cervical cancer (CC). Latvia has a high incidence of CC compared with the average incidence in the European Union. This study aims to fill the data gap on the HR-HPV burden in Latvia, providing information on its prevalence and associated factors. METHODS: The cross-sectional study was conducted from February 2021 to April 2022. Participants 25-70 years old visiting a general practitioner (general population) or those referred to a colposcopy clinic with changes in their cervical cytology (colposcopy population) collected vaginal self-sample and completed a paper-based questionnaire. Samples were analyzed with Cobas 6800 System (Roche) for HPV16, HPV18 and other HR-HPV (HPV31/33/35/39/45/51/52/56/58/59/66/68). Descriptive statistics for categorical variables were performed. The Chi-square test was used to determine for the statistical significance of differences in the proportions of the dependent variable between subgroups of the independent variable. Univariate and multivariate binary logistic regression were used to identify factors associated with positive HR-HPV status. Results were considered statistically significant at P < 0.05. RESULTS: A total of 1274 participants provided a valid sample. The prevalence of any HR-HPV infection was 66.8% in the colposcopy group and 11.0% in the general population. Factors associated with positive HR-HPV status were marital status single/divorced/widowed (vs. married/cohabiting) [adjusted OR (aOR) 2.6; P = 0.003], higher number of lifetime sex partners [aOR 5.1 (P < 0.001) and 4.0 (P = 0.001)] for six or more and three to five partners in the general population; in the colposcopy group, the statistical significance remained only for Latvian ethnicity (vs. other) (aOR 1.8; P = 0.008) and current smoking (vs. never) (aOR 1.9; P = 0.01). CONCLUSION: We documented a comparison to European Union HR-HPV infection burden in Latvia. Any HR-HPV positivity was significantly associated with sexual and other health behavior.

INTRODUCTION: This study explores the immunogenetic associations of human leukocyte antigens (HLA) and the calcium release-activated calcium modulator 1 (ORAI1) and stromal interaction molecule 1 (STIM1) genes in HIV-1âpositive patients with HIV-related skin disorders. METHODS: This study assessed the distribution of variants of HLA class II alleles and expression levels of ORAI1 and STIM1 genes in the blood between HIV-1âpositive patients with HIV-related skin disorders and the control group with no HIV within the Latvian population. RESULTS: The research group comprised 115 HIV-1âpositive patients with HIV-related skin disorders, and the control group included 80 healthy individuals. Risk alleles (HLA- DQB1*02:01-0301 and HLA-DQA1*01:01-0501) and protective alleles (HLA-DRB1*07-13, DRB1*01-13, DRB1*04-11, and HLA-DQA1*05:01-0501) showed statistical significance in the groups. In 38 out of 115 patients, higher expression levels of ORAI1 and STIM1 genes were detected in the blood at the beginning of treatment. A significantly higher level of the microribonucleic acid (mRNA) ORAI1 gene was also found in the control group. CONCLUSIONS: The results demonstrate that HLA class II alleles are associated with a trend toward risk/protection concerning HIV-related skin disorders in HIV-1âpositive patients. It was also shown that a low level of ORAI1 mRNA and the risk allele HLA-DQB1*0201-0301 were simultaneously present in the research group.

Chronic rhinosinusitis (CRS) is a complex syndrome with various inflammatory mechanisms resulting in different patterns of inflammation that correlate with the clinical phenotypes of CRS. Our aim was to use detected IL-1, IL-4, IL-6, IL-7, IL-8, IL-10, IL-12, Ki 67, HBD-2, HBD-3, and LL-37 to classify specific inflammatory endotypes in chronic rhinosinusitis with the tissue of nasal polyps (CRSwNP). Samples from 35 individuals with primary and recurrent CRSwNP were taken during surgery. The tissues were stained for the previously mentioned biomarkers immunohistochemically. A hierarchical cluster analysis was performed. The clinical parameters were compared between clusters. Five clusters had significantly different biomarkers between groups. There were no significant differences in the clinical parameters, except for the Lund-Mackay score, which was significantly higher in cluster 4 compared to that of cluster 1 (p = 0.024). Five endotypes of (CRSwNP) are characterized by different combinations of type 1, type 2, and type 3 tissue inflammation patterns. In the Latvian population, endotypes associated with neutrophilic inflammation or a combination of neutrophilic inflammation and type 2 inflammation are predominant. Increased proliferation marker Ki 67 values are not associated with more severe inflammation in the tissue samples of chronic rhinosinusitis with nasal polyps.

Background and Objectives: Breastmilk is the safest and most suitable food for an infant, playing the role of their first vaccine and containing all the essential nutrients for the first months of life. The World Health Organisation recommends exclusive breastfeeding for the first 6 months of life and continued breastfeeding while introducing a child to complementary foods until 2 years and beyond. According to Latvian statistics from 2022, only 27.4% of babies were breastfed for 12 months. The aim of this study was to determine the socio-economic factors and factors related to pregnancy, childbirth and postpartum that influence breastfeeding for more than 6 months in Latvia. Materials and Methods: Data were used from the cross-sectional survey "Research on factors and behaviours affecting the sexual and reproductive health of the population of Latvia", which was conducted in 2023. A study sample was randomised and stratified by gender and five age groups. The analyses in this study are based on a sample of women who had given birth at least once (n = 1407), and the dependent variable was the duration of breastfeeding their last child. Binary logistic regression was conducted to identify the associated factors. Results: The point prevalence of longer duration of breastfeeding for the last child was 47.9% (n = 674). The odds of longer breastfeeding duration were higher among mothers who did not smoke during pregnancy (vs. smokers, aOR 2.1, p < 0.001), of Latvian nationality (vs. Russian, aOR 1.3, p = 0.03), who had two childbirth (vs. one, aOR 1.5, p = 0.003), who had the highest level of education (vs. primary education, aOR 2.0, p = 0.03), started breastfeeding immediately after the birth (vs. later than the first day, aOR 1.7, p = 0.01) or on the first day (vs. later, aOR 1.6, p = 0.01). Conclusions: We documented socio-demographic pregnancy and childbirth factors associated with longer breastfeeding durations. Efforts to promote breastfeeding practices should target mothers from the most vulnerable groups.

BACKGROUND: Latvia has the second highest suicide rate in the European Union - with a total population age-standardized suicide rate of 16.1 per 100,000 inhabitants. AIMS: We aimed to assess the prevalence of different types of self-reported suicidal behaviours in Latvia and determine the associated sociodemographic and health-related factors. METHODS: This study was based on secondary data obtained from the Health Behaviour Among Latvian Adult Population survey. A representative sample of the general population was used, aged 15 to 64 years in 2010, 2012, 2014; and 15 to 74 years in 2016 and 2018 (n = 16,084). Respondents were asked to report the occurrence of life weariness, death wishes, suicidal ideation, suicidal plans and suicide attempts during the previous year. We assessed socio-demographics and health-related factors associated with suicidality. We performed univariate analysis and constructed stepwise multivariate logistic regression models. RESULTS: In 2010 to 2018, 15.6% of responders reported some type of suicidal behaviour (95% CI [15.1, 16.2]). Sociodemographic factors - including non-cohabitation status and Latvian nationality - were associated with mild (life-weariness and death wishes) and serious (suicidal ideation, plans to commit suicide, suicide attempts) types of behaviour. Older age was associated with mild suicidal behaviours, whereas lower educational levels were associated with serious suicidal behaviours. Diagnosed depression, self-reported depression, self-reported anxiety, stress, low mood, alcohol intake habits with heavy drinking episodes (less than monthly, monthly and weekly), perceived health as average or below average, disuse of primary health services were associated with mild and serious types of suicidal behaviour. Current smoking status and absenteeism were associated with mild suicidal behaviour types. Self-reported insomnia, having at least two somatic diagnoses, occasional smoking status, absenteeism with 11 or more days in the last year, receiving disability pension were associated with serious suicidal behaviour types. Musculoskeletal diseases exhibited preventive effects. CONCLUSIONS: Our findings indicate that certain groups of individuals might exhibit greater vulnerability to suicidality.

Background and Objectives: Acute appendicitis is the most common abdominal emergency requiring surgery and it has an estimated lifetime risk of 6.7 to 8.6%. The COVID-19 pandemic has transformed medical care worldwide, influencing diagnostic tactics, treatment modalities and outcomes. Our study aims to compare and analyze management of acute appendicitis before and during the first and second waves of the pandemic. Materials and Methods: Patients suffering acute appendicitis were enrolled retrospectively in a single-center study for a 10-month period before the pandemic (pre-COVID-19 period: 1 March to 31 December 2019) and during the pandemic (COVID-19 period: 1 March to 31 December 2020). The total number of patients, disease severity, diagnostic methods, complications, length of hospitalization and outcomes were analyzed. Results: A total number of 863 patients were included, 454 patients in the pre-COVID-19 period and 409 patients in the COVID-19 period. Compared to the pre-COVID-19 period, the number of complicated appendicitis increased in the COVID-19 period (24.4% to 37.2%; p < 0.001). The proportion of laparoscopic appendectomies increased during the COVID-19 period but did not show statistically significant differences between periods. In both time periods, we found that open technique was the chosen surgical approach more frequently in elderly patients (p < 0.001). Generalized peritonitis was significantly more common during the COVID-19 period (3.5% vs. 6.1%, p < 0.001). The postoperative course of patients was similar in the pre-COVID-19 period and during the COVID-19 period, with no significant differences in ICU admissions, overall hospital stay or morbidity. Conclusions: The COVID-19 pandemic has led to a significant increase in complicated forms of acute appendicitis; however, no significant impact was observed in terms of diagnostic or treatment approach.

Natural sciences provide several modern methodologies that could be successfully applied in archaeological studies. In this pilot study, archaeological human remains from two Iron Age cemeteries (7th-twelfth centuries AD), Lejasbiteni and Cunkani-Drengeri, which are located in different regions of Latvia, were studied. We applied ancient DNA (aDNA) and tooth enamel peptide analysis to determine the biological sex of the individuals. In addition, aDNA analysis was used to perform mtDNA haplogroup analysis. In most cases, the results of aDNA analysis regarding the biological sex of individuals coincided with the gender assigned based on grave orientation and grave goods. The results of sex determination using peptide analysis in all four individuals for whom data were available matched the possible gender. Of the 17 samples that had sufficient DNA for sequencing, seven samples had enough reads to perform mtDNA haplogroup analysis. The H2a2a, I4a1, H2a2a1, and H16c mtDNA haplogroups were identified in the individuals from the Lejasbiteni cemetery, while the T2b and K1a + 150 mtDNA haplogroups were identified in the individuals from the Cunkani-Drengeri cemetery. Overall, the obtained results demonstrated the feasibility of applying aDNA and tooth enamel peptide analysis for biological sex determination within archaeological studies. The availability of human aDNA data will be highly useful for investigating the demographic history and social structures in Iron Age Latvia.

INTRODUCTION: Hypopituitarism is a chronic disease characterized by partial or complete absence of secretion of one or more pituitary hormones. Delayed diagnosis can have serious consequences during the neonatal period and adulthood. MATERIAL AND METHODS: A retrospective study was conducted on patients who had started treatment in the Children's Clinical University Hospital from 1 January 1995 to 31 December 2020. In total 243 patients were included; they were divided into 3 subgroups: isolated growth hormone deficiency, multiple pituitary hormone deficiency, and panhypopituitarism. RESULTS: The prevalence of hypopituitarism in Latvia is about 45 cases per 100,000 live births. The average detection age of abnormal growth in Latvia is 8 years and 3 months. Most cases had isolated growth hormone deficiency, at 67.1% (n = 163), followed by cases of multiple pituitary hormone deficiency, at 26.3% (n = 64), and cases of panhypopituitarism, at 6.6% (n = 16). Abnormalities in MRI were found in 44.7% (n = 101) of patients. The most best therapeutic effect was achieved in the first year of treatment: with growth of an average of 9.3 cm (+0.1 SD) for isolated growth hormone deficiency, 9.0 cm (+0.6 SD) for multiple pituitary hormone deficiency, and 11.7 cm (+1SD) for patients with panhypopituitarism. CONCLUSIONS: It is important to increase awareness and promote early diagnosis for hypopituitarism patients in Latvia and in Europe. More attention should be paid to education about growth restriction problems to parents, caregivers, and other specialists. The treatment should be adjusted individually with the focus not only on physical and mental health but also on safety and treatment costs.

Ultraviolet radiation is known as one of the major contributors to skin malignancies, including basal cell carcinoma (BCC), which is the most common type of skin cancer. It is a heterogeneous tumor, which presents with various types that are stratified into low- and high-risk tumors. Sunlight is important for overall health and vitamin D synthesis in the skin, whereas deviations from the optimal level of vitamin D are shown to be associated with the risk of the development of BCC. The accumulating evidence suggests the ability of vitamin D to antagonize the Sonic Hedgehog (SHH) signaling, the key tumor pathway, and play a protective role in the development of BCC. Additionally, a vitamin D binding protein (DBP) is shown to be implicated in the complex regulation of vitamin D. Here, we aimed to explore serum vitamin D in patients with different primary and recurrent BCC of the head and neck and investigate cutaneous DBP and SHH indices, confirmed immunohistochemically in these subjects. According to the results, 94.9% of the Latvian cohort of BCC patients were found to be deficient in vitamin D. No significant differences in serum vitamin D levels were found between genders, primary and recurrent tumors, and different types of BCC. Serum vitamin D was inversely associated with tumor size. Susceptible male individuals with low blood vitamin D levels were recognized at risk of developing aggressive and recurrent BCC confirmed by the use of hierarchical clustering analysis. In smaller tumors with a favorable course, such as superficial and nodular BCC, the association between high DBP and low SHH tissue expression was found, providing supportive evidence of the existence of a link between vitamin D, proteins involved in its metabolism, as exemplified by the DBP and SHH signaling pathway. The assumption of a deficiency in the protective effect of vitamin D in patients with high-risk BCCs was proposed in low DBP and high SHH tissue indices. New extensions to existing knowledge and characterization of the BCC signaling pathways and their cross-talk with vitamin D are warranted when searching for a preferential effect of vitamin D on skin cancer.

Background and Objectives: During pregnancy, iron deficiency anaemia is a common problem associated with health risks for both the mother and her foetus/infant. This study aimed to investigate the prevalence of iron deficiency, iron deficiency anaemia, and related dietary patterns in pregnant women in Latvia. Materials and Methods: This cross-sectional, multicentre study included pregnancy data from 974 women. The sample selection was based on the stratification principle (population of women of childbearing age in regions of Latvia). Maternal demographic details, anthropometric measurements, iron status, dietary patterns, and supplementation information were obtained from maternal files and during interviews held in eight outpatient departments of medical institutions and maternity departments. The prevalence was assessed. Chi-square tests and logistic regression were used to identify associations between iron deficiency and sociodemographic characteristics, dietary patterns, and iron supplement intake during pregnancy. The criterion used for the diagnosis of iron deficiency anaemia is a Hb level <110 g/L in the 1st and 3rd trimesters and <105 g/L during the 2nd trimester as recommended by the WHO. However, the UK guideline was used for borderline iron deficiency, which is an SF level <30 µg/L in all trimesters. Results: The observed prevalence of anaemia was 2.8% in the first trimester, 7.9% in the second trimester, and 27.0% in the third trimester. The prevalence of iron deficiency was 46.7% in the first trimester, 78.1% in the second trimester, and 91.7% in the third trimester. No associations with dietary patterns were found. Single women had 1.85 times the odds (95% CI 1.07 to 3.18) of being anaemic than married women. Conclusions: Iron deficiency affects a large proportion of pregnant women in Latvia in all trimesters, with iron deficiency anaemia affecting pregnant women in the third trimester. Monitoring and intervention should be performed in a timely and more targeted manner.

Wastewater-based epidemiology (WBE) was applied to evaluate seasonal variations of the consumption of pharmaceuticals (i.e. antibiotics, NSAIDs, antiepileptics, antihypertensives and others), caffeine, alcohol and nicotine in Latvia throughout 2021. In addition, weekly variation of caffeine, nicotine and alcohol consumption was investigated. Pronounced seasonality was observed in the consumption of antibiotics and decongestants, as well as caffeine, nicotine and alcohol. Correlation with COVID-19 statistics was observed in the case of macrolide antibiotics and antiasthmatic salbutamol. Comparison of the estimated consumption values obtained using the WBE approach and the statistics revealed that the majority of compounds data are in good agreement except angiotensin II receptor blocker group antihypertensives where the most overestimated consumption values were observed.

BACKGROUND: Age-standardised noncommunicable disease (NCD) mortality and the proportion of the elderly population in Latvia are high, while public health and health care systems are underresourced. The emerging COVID-19 pandemic raised concerns about its detrimental impact on all-cause and noncommunicable disease mortality in Latvia. We estimated the timing and number of excess all-cause and cause-specific deaths in 2020 in Latvia due to COVID-19 and selected noncommunicable diseases. METHODS: A time series analysis of all-cause and cause-specific weekly mortality from COVID-19, circulatory diseases, malignant neoplasms, diabetes mellitus, and chronic lower respiratory diseases from the National Causes of Death Database from 2015 to 2020 was used by applying generalised additive modelling (GAM) and joinpoint regression analysis. RESULTS: Between weeks 14 and 52 (from 1 April to 29 December) of 2020, a total of 3111 excess deaths (95% PI 1339 - 4832) were estimated in Latvia, resulting in 163.77 excess deaths per 100 000. Since September 30, with the outbreak of the second COVID-19 wave, 55% of all excess deaths have occurred. Altogether, COVID-19-related deaths accounted for only 28% of the estimated all-cause excess deaths. A significant increase in excess mortality was estimated for circulatory diseases (68.91 excess deaths per 100 000). Ischemic heart disease and cerebrovascular disease were listed as the underlying cause in almost 60% of COVID-19-contributing deaths. CONCLUSIONS: All-cause mortality and mortality from circulatory diseases significantly increased in Latvia during the first pandemic year. All-cause excess mortality substantially exceeded reported COVID-19-related deaths, implying COVID-19-related mortality during was significantly underestimated. Increasing mortality from circulatory diseases suggests a negative cumulative effect of COVID-19 exposure and reduced access to healthcare services for NCD patients.

Background and Objectives: The aim of the study was to analyze the prevalence of cardiovascular risk factors (RFs) in Latvia from the population-based cross-sectional study performed in 2019−2020 and to compare the results with a similar study done in 2009−2010. Materials and Methods: The target sample of 6000 individuals representing a cross-section of Latvia's inhabitants (aged 25−74) was formed using stratified two-stage cluster sampling. The survey had two components: (1) an interview using a pre-specified questionnaire and (2) physical examination (height, weight, arterial pressure) and collection of venous blood samples to measure levels of fasting glucose (Glu), total cholesterol (TC), high and low-density lipoprotein cholesterol (HDL-C/LDL-C), and triglycerides (Tg). In total, 4070 individuals were interviewed (32% non-response), from which 2218 (55%) individuals underwent physical examination and collection of blood samples. Results: The most frequently observed RFs were high LDL-C (62.0%), smoking (45.3%), and arterial hypertension (36.8%), while the prevalence of self-reported high cholesterol and hypertension was 19.3 and 18.6%, respectively. A decrease in the prevalence of hypertension, high LDL-C, and Glu was noted. Smoking decreased in younger men. The mean number of five most important cardiovascular RFs was 2.0 (95% confidence interval (CI) 2.0, 2.1); 2.3 (95% CI 2.2, 2.4) for men and 1.8 (95% CI 1.7, 19) for women. The average number of RFs has decreased by 0.3 in 10 years, t(5883) = −7.2, p < 0.001. Conclusions: Although the prevalence of cardiovascular RFs remains noteworthy, an improvement in the risk profile of the Latvian population has been observed over the past decade. The study shows subjective self-underestimation of cardiovascular risk.

The problem of painful and disabling work-related musculoskeletal disorders (MSDs) is increasing in many employment sectors of Latvia. Official statistics may underestimate the proportion of affected employees, causing delays in preventive interventions, ineffective rehabilitation, and a reduction of the workforce. This study investigated the prevalence of painful health conditions among Latvian workers by analyzing survey data and comparing these to official statistics on registered occupational diseases (ODs). A total of 2,446 workers participated in the state-level "Work conditions and risks in Latvia, 2017-2018" survey that included questions about pain lasting longer than 3 days during the previous year. The frequency of subjective reports on the presence, severity, and location of pain and related behaviors was assessed in relation to sex, age, education, and job position. Descriptive statistics and cross tabulation with the chi-squared test as well as multinomial logistic regression were applied to the data. Overall, 27.7% of respondents (n = 678) reported experiencing pain, predominantly in the lower back (14.3%) and mostly moderate (47.1%) or severe (45.1%). Only one-fifth of respondents (20.5%) took sick leave from work and one-third (29.0%) did not take action to alleviate their pain. Participants aged 55-74 years had a significantly higher odds ratio (OR) for pain in at least one body region-including hands and legs-than those aged 18-24 years. Women had significantly higher odds of headache (OR = 2.55) and neck pain (OR = 1.85) than men. Respondents with a primary or elementary education level had higher odds of pain in at least one body region (OR = 1.60) and in the lower back (OR = 1.86), while those with secondary education had higher odds of pain in hands (OR = 1.51) than employees with higher education. Unskilled workers had significantly higher odds of pain in hands (OR = 2.42) and legs (OR = 2.12) than directors. Official data revealed a dramatic increase in the proportion of MSDs and related disabilities in the last decade, reaching 75.5% of all first registered ODs in 2019. These results demonstrate a high prevalence of painful conditions among Latvian employees; urgent attention to diagnostics, treatment, and prevention is needed to ensure the musculoskeletal health and productivity of this population.

BACKGROUND: Increased life expectancy, developments in medicine and intracardiac devices, accessibility of cardiac surgery, decrease in the prevalence of rheumatic heart disease are changing infective endocarditis patient profile and thus risk factors for the adverse events. This single-center-based study covering the whole Latvian population aimed to assess the intrahospital and 3-year mortality of infective endocarditis patients who underwent cardiac surgery, as well as risk factors and laboratory indices predictive of adverse outcomes of the disease. METHODS: Clinical profiles, data of laboratory and instrumental analyses, operation and intensive care unit records of cardiac surgery patients treated in Pauls Stradins Clinical University Hospital, Riga, Latvia, between 2015 and 2019 were analyzed. RESULTS: We analyzed data from 242 episodes of surgically treated infective endocarditis in 233 patients. The median age of patients was 57.00 (45.00-68.00) years. The rate of intrahospital mortality was 11.16%. Risk factors associated with mortality in the univariate analyses were S. aureus infection (HR=2.27, 95% CI: 1.36-3.80; P=0.002) and systemic embolization of vegetations (HR=1.63, 95% CI: 1.00-2.64; P=0.048). Perivalvular complications (HR=1.98, 95% CI: 1.19-3.29; P=0.009) were found to be independently associated with mortality in multivariate analysis (HR=1.99, 95% CI: 1.05-3.78; P=0.035). One-year survival was 78.3%, whereas three-year -71.3%. CONCLUSIONS: Intrahospital mortality of surgically treated IE patients was 11.2%; however, one- and three-year mortality was 21.7 and 28.7%, respectively. Perivalvular complications were independently associated with mortality. Laboratory indices were not predictive of adverse outcomes.

Considering the multitudes of people who spend their time working indoors in public premises and workplaces, it is worth knowing what their level of exposure is to natural radioactive radon gas, the second most widespread and dangerous carcinogen for lung cancer development after cigarette smoking. This state-level study covered most of the territory of Latvia and conducted 941 radon measurements with Radtrack2, placed for 4-6 months in the premises of public companies, educational institutions, medical care institutions, etc. The study found that 94.7% of samples did not exceed the national permissible limit (200 Bq/m3), the level at which preventive measures should be initiated. The median value of average specific radioactivity of radon in these premises was 48 Bq/m3 (Q1 and Q3 being 27 and 85 Bq/m3), which is below the average of the European region. Slightly higher concentrations were observed in well-insulated premises with plastic windows and poorer air exchange, mostly in schools (59 (36, 109) Bq/m3) and kindergartens (48 (32, 79) Bq/m3). Industrial workplaces had surprisingly low radon levels (28 (16, 55) Bq/m3) due to strict requirements for air quality and proper ventilation. Public premises and workplaces in Latvia mostly have low radon concentrations in the air, but more attention should be paid to adequate ventilation and air exchange.

BACKGROUND: The COVID-19 pandemic has challenged the ability of healthcare systems to ensure the continuity of health services for patients with non-communicable diseases (NCDs). The issue of remote consultations has emerged. Before the COVID-19 pandemic, remote consultations were not routinely provided or covered by public health funding in Latvia. This study aimed to describe the dynamics of consultations and the volume of remote consultations provided for patients with particular NCD and explore clinicians' experiences of providing remote consultations during the first wave of the COVID-19 pandemic in Latvia. METHODS: A mixed-method study focusing on the first wave of the COVID-19 pandemic in Latvia in Spring 2020 was conducted. Quantitative data from the National Health Services were analysed to assess the dynamics of consultations for patients with selected NCDs. Qualitative data were collected through 34 semi-structured interviews with general practitioners (GPs) and specialists and were analysed using an inductive thematic analysis. Purposive maximum variation sampling was used for participant selection. RESULTS: During the period with the strongest restrictions of scheduled on-site consultations, a decrease in the total number of consultations was observed for a variety of NCDs. A significant proportion of consultations in this period were provided remotely. GPs provided approximately one-third of cancer-related consultations and almost half of consultations for the other selected conditions remotely. Among specialists, endocrinologists had the highest proportion of remote consultations (up to 72.0%), while urologists had the lowest (16.4%). Thematic analysis of the semi-structured interviews revealed five themes: 1) Adjusting in a time of confusion and fear, 2) Remote consultations: safety versus availability, 3) Sacrifice and loss of privacy, 4) Advantages and disadvantages of communication technologies, and 5) Different form of communication and a health literacy challenge. CONCLUSIONS: During the first wave of the COVID-19 pandemic in Latvia, disruptions to health care services decreased the total number of consultations for patients with NCDs provided by both GPs and specialists. In this period, remote consultations proved to be an important instrument for ensuring the continuity of health care for patients with NCDs, and the necessity to develop a well-designed system for telemedicine in Latvia was highlighted.

The EU member states' healthcare and health-related research sectors are both characterized by an emerging infrastructural coalescence on a national and European level. The culmination of this coalescence is the planned creation of a European Health Data Space, an EU-wide infrastructure for the processing of personal data for healthcare and for secondary uses such as scientific research. In contrast to growing technical interoperability, the legal framework for such integration is not yet defined in detail, particularly with regard to data protection law. Its development is accompanied by discussions about divergent member state implementations of the EU General Data Protection Regulation (GDPR) that affect data sharing between healthcare and scientific research actors and across various sectors driven by divergent processing purposes. The article presents four member states' main rules on data sharing based on the respective provision of the GDPR in six health-related contexts regarding data sharing across the healthcare and research sector and between the main actors of those sectors. The striking differences are then evaluated from the perspective of their factual effect on European data sharing depending on the legal characteristics of the GDPR provisions they rely on. Against this backdrop, the planned regulatory measures for the setup of the European Health Data Space are introduced and evaluated with regard to further harmonization between member states' laws and possibilities to overcome divergences in data protection rules relevant for European data sharing. The results of the analysis point to the conclusion that the destructive effect of divergent member state rules depends on the legal qualification of the EU provisions they rely on and that this qualification also determines which further EU regulatory measure would be the most effective to set the framework for the European Health Data Space.

Background and objectives: There is still an uncertainty regarding the clinical symptomatology and the diagnostic criteria in terms of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), as different diagnostic criteria exist. Our aim is to identify the core symptoms of ME/CFS in the outpatient setting in Riga; to distinguish symptoms in patients with ME/CFS and those with symptoms of fatigue; and to investigate patient thoughts on the onset, symptoms, treatment and effect of ME/CFS. Materials and methods: Total of 65 Caucasian patients from an ambulatory care setting were included in the study. Questionnaires, specialist evaluation of the patients and visual analogue scale (VAS) measurements were used to objectify the findings. Results: The study showed that ME/CFS with comorbidities is associated with a more severe disease. A negative correlation was found regarding an increase in age and number of current symptoms, as well as an increase in VAS score and the duration of fatigue and age in the ME/CFS without comorbidities group. Conclusions: Comorbidities tend to present with a more severe course of ME/CFS. Fatigue, myalgia, arthralgia and sleep disturbances tend to be more prevalent in the ME/CFS patients compared to the non-ME/CFS patients. VAS score has a tendency to decrease with age and duration of fatigue. Nonsteroidal anti-inflammatory drugs are the most commonly used pharmacological drug class that reduces ME/CFS symptoms.
