From virus structure to chromatin: X-ray diffraction to three-dimensional electron microscopy.

Early influences led me first to medical school with a view to microbiology, but I felt the lack of a deeper foundation and changed to chemistry, which in turn led me to physics and mathematics. I moved to the University of Cape Town to work on the X-ray crystallography of some small organic compounds. I developed a new method of using molecular structure factors to solve the crystal structure, which won me a research studentship to Trinity College Cambridge and the Cavendish Laboratory. There I worked on the austenite-pearlite transition in steel. This is governed by the dissipation of latent heat, and I ended up numerically solving partial differential equations. I used the idea of nucleation and growth during the phase change, which had its echo when I later tackled the assembly of Tobacco mosaic virus (TMV) from its constituent RNA and protein subunits. I wanted to move on to X-ray structure analysis of large biological molecules and obtained a Nuffield Fellowship to work in J.D. Bernal's department at Birkbeck College, London. There, I met Rosalind Franklin, who had taken up the study of TMV. I was able to interpret some of Franklin's beautiful X-ray diffraction patterns of the virus particle. From then on, my fate was sealed. After Franklin's untimely death in 1958, I moved in 1962 to the newly built MRC Laboratory of Molecular Biology in Cambridge, which, under Max Perutz, housed the original MRC unit from the Cavendish Laboratory. I was thus privileged to join the Laboratory at an early stage in its expansion and consequently able to take advantage of, and to help build up, its then unique environment of intellectual and technological sophistication. There I have remained ever since.

Human nasal microbiota shifts in healthy and chronic respiratory disease conditions.

BACKGROUND: An increasing number of studies investigate various human microbiotas and their roles in the development of diseases, maintenance of health states, and balanced signaling towards the brain. Current data demonstrate that the nasal microbiota contains a unique and highly variable array of commensal bacteria and opportunistic pathogens. However, we need to understand how to harness current knowledge, enrich nasal microbiota with beneficial microorganisms, and prevent pathogenic developments. RESULTS: In this study, we have obtained nasal, nasopharyngeal, and bronchoalveolar lavage fluid samples from healthy volunteers and patients suffering from chronic respiratory tract diseases for full-length 16 S rRNA sequencing analysis using Oxford Nanopore Technologies. Demographic and clinical data were collected simultaneously. The microbiome analysis of 97 people from Lithuania suffering from chronic inflammatory respiratory tract disease and healthy volunteers revealed that the human nasal microbiome represents the microbiome of the upper airways well. CONCLUSIONS: The nasal microbiota of patients was enriched with opportunistic pathogens, which could be used as indicators of respiratory tract conditions. In addition, we observed that a healthy human nasal microbiome contained several plant- and bee-associated species, suggesting the possibility of enriching human nasal microbiota via such exposures when needed. These candidate probiotics should be investigated for their modulating effects on airway and lung epithelia, immunogenic properties, neurotransmitter content, and roles in maintaining respiratory health and nose-brain interrelationships.

Cancer mortality and morbidity among patients with schizophrenia: A hospital-based cohort study, 1992-2020.

OBJECTIVE: Due to the inconsistency of the evidence about the cancer risk among patients with schizophrenia, the aim of this study was to analyse cancer mortality and morbidity in patients with schizophrenia treated in a single centre in Lithuania during the study period of 1992-2020. MATERIALS AND METHODS: A retrospective cohort study was conducted in Vilnius Republican Psychiatric Hospital, the biggest specialised psychiatric hospital in Lithuania, with approximately 5000 hospital admissions annually. The patients' cohort was established by identifying all patients with the diagnosis of schizophrenia (ICD-10 code F20) in the hospital database from 1 January 1992 until 31 December 2017. The cancer cases and cancer deaths in the cohort were identified in the Lithuanian Cancer Register through linkage procedures. The analysis of risk was based on a comparison of observed and expected numbers of cancers and deaths. Expected number of cancer cases were calculated by multiplication of the exact person-years under observation in the cohort by sex, calendar year and a 5-year age-group-specific national incidence and mortality rate. All statistical analyses were carried out using STATA 15 statistical software. RESULTS: During the follow-up, out of 8553 patients, 673 cases of cancer were diagnosed in both sexes. Statistically significantly lower risk for overall cancer incidence was observed in men (SIR 0.74, 95% CI 0.66-0.83), but not in women (SIR 1.07, 95% CI 0.97-1.18). Statistically significant lower overall cancer mortality risk was observed in men (SMR 0.82, 95% CI 0.70-0.96), while in the women's group, risk of cancer deaths was significantly higher compared to the general population (SMR 1.28, 95% CI 1.11-1.48). We observed lower risk for pancreatic cancer (SIR 0.36, 95% CI 0.14-0.96), non-melanoma skin cancer (SIR 0.54, 95% CI 0.33-0.88) and prostate cancer (SIR 0.69, 95% CI 0.55-0.87) in men and higher risk for malignant neoplasm of liver (SIR 2.58, 95% CI 1.53-4.36) and skin melanoma (SIR 2.03, 95% CI 1.12-3.66) in men and for breast cancer (SIR 1.38, 95% CI 1.14-1.66) and corpus uteri cancer (SIR 1.56, 95% CI 1.18-2.07) in women. CONCLUSIONS: The current results of our study indicate lower risk of overall cancer incidence and mortality in male patients with schizophrenia, while female patients had a higher mortality risk, alongside variations in the risk of different cancer types. This information is important not only for patients, but for healthcare specialists to develop effective disease-specific preventive interventions and programmes.

Validation of the Lithuanian version of the Prolapse Quality-of-Life questionnaire.

INTRODUCTION AND HYPOTHESIS: We aimed to translate and validate the Lithuanian version of the Prolapse Quality-of-Life (P-QOL) questionnaire. METHODS: The P-QOL questionnaire was translated into Lithuanian and administered to women recruited from a gynaecology outpatient clinic at a tertiary referral centre. The scores of the final version were compared in symptomatic (n = 137) and asymptomatic (n = 137) women and with findings on vaginal examination using the Pelvic Organ Prolapse Quantification system. The reliability was assessed by calculating Cronbach's alpha and by performing a test-retest analysis. RESULTS: There was a significant difference in median score for each P-QOL domain between symptomatic and asymptomatic women (p < 0.001). P-QOL scores correlated significantly with the stage of urogenital prolapse in most domains. High internal consistency was shown in all domains with a Cronbach's alpha range of 0.775 to 0.958, except for the "social limitations" domain, which was shown to be acceptable (0.647). Test-retest reliability was also high in all domains (p < 0.05). CONCLUSION: The Lithuanian version of the P-QOL questionnaire has proven to be a valid, reliable and easily comprehensible instrument for assessing symptom severity and impact on the quality of life of Lithuanian-speaking women with urogenital prolapse.

Etiology, Clinical Presentation, and Outcomes of Bacterial Meningitis in Adult Patients: A Retrospective Study in Lithuania (2018-2021).

BACKGROUND Bacterial meningitis is a serious and life-threatening condition that requires prompt diagnosis and treatment. This retrospective study aimed to identify causes, presentation, and predictive factors for outcomes of community-acquired bacterial meningitis in 86 adults in Vilnius, Lithuania between 2018 and 2021. MATERIAL AND METHODS We performed a retrospective study of demographic, clinical, and laboratory records of 86 adult patients admitted to Vilnius University Hospital Santaros Clinics with a diagnosis of acute bacterial meningitis during the period of 2018-2021. RESULTS Of 86 patients, 54 (62.79%) were men. The median (Md) age of patients was 58 (range, 18-83) years and the median duration of hospitalization was 20 (range, 3-92) days. Patients were first hospitalized in the Intensive Care Unit (ICU) in 59.3% of cases. The most prevalent concerns were headache (66.28%), febrile temperature (56.98%), general fatigue (53.49%), and confusion/sleepiness (52.33%). Of 57 (66.28%) etiologically confirmed cases, the most prevalent agent was Listeria monocytogenes (29.82%), followed by Streptococcus pneumoniae (28.07%) and Neisseria meningitidis (28.07%). Patients with meningitis caused by L. monocytogenes were the oldest (P=0.003) and had the longest hospitalization (P<0.001). Fatigue was the prominent symptom in patients with meningococcal meningitis (81.2%, P=0.010). Twelve patients (13.95%) have died. Advanced age and low (<100 cells per µL) white blood cell (WBC) count in cerebrospinal fluid (CSF) were associated with lethal outcome, whereas headache was associated with favorable outcome. CONCLUSIONS Clinical characteristics of community-acquired acute bacterial meningitis differ based on etiological factors. Patient age, CSF WBC count, and headache may be significant predictive factors for outcomes of bacterial meningitis.

Algorithm for detection and screening of familial hypercholesterolemia in Lithuanian population.

BACKGROUND: Familial hypercholesterolemia (FH) is one of the most common autosomal dominant diseases. FH causes a lifelong increase in low-density lipoprotein cholesterol (LDL-C) levels, which in turn leads to atherosclerotic cardiovascular disease. The incidence of FH is widely underestimated and undertreated, despite the availability and effectiveness of lipid-lowering therapy. Patients with FH have an increased cardiovascular risk; therefore, early diagnosis and treatment are vital. To address the burden of FH, several countries have implemented national FH screening programmes. The currently used method for FH detection in Lithuania is mainly based on opportunistic testing with subsequent cascade screening of index cases' first-degree relatives. METHODS: A total of 428 patients were included in this study. Patients with suspected FH are referred to a lipidology center for thorough evaluation. Patients who met the criteria for probable or definite FH according to the Dutch Lipid Clinic Network (DLCN) scoring system and/or had LDL-C > = 6.5 mmol/l were subjected to genetic testing. Laboratory and instrumental tests, vascular marker data of early atherosclerosis, and consultations by other specialists, such as radiologists and ophthalmologists, were also recorded. RESULTS: A total of 127/428 (30%) patients were genetically tested. FH-related mutations were found in 38.6% (n = 49/127) of the patients. Coronary artery disease (CAD) was diagnosed in 13% (n = 57/428) of the included patients, whereas premature CAD was found in 47/428 (11%) patients. CAD was diagnosed in 19% (n = 9/49) of patients with FH-related mutations, and this diagnosis was premature for all of them. CONCLUSIONS: Most patients in this study were classified as probable or possible FH without difference of age and sex. The median age of FH diagnosis was 47 years with significantly older females than males, which refers to the strong interface of this study with the LitHir programme. CAD and premature CAD were more common among patients with probable and definite FH, as well as those with an FH-causing mutation. The algorithm described in this study is the first attempt in Lithuania to implement a specific tool which allows to maximise FH detection rates, establish an accurate diagnosis of FH, excluding secondary causes of dyslipidaemia, and to select patients for cascade screening initiation more precisely.

Experiences of childbirth care in Lithuania and Romania: Insights from the European Babies Born Better survey.

BACKGROUND: Data on experience and satisfaction of users are essential for improvement of health care, especially in the field of childbirth. The aim of this study was to compare childbirth care experiences in Lithuania and Romania. METHODS: Data derived from the EU Babies Born Better online survey were analyzed. Parturients from Lithuania (N = 373) and Romania (N = 359) who had given birth within the last 5 years were included. Participants were asked to (1) describe the best things in childbirth care and (2) suggest changes in the care received at their birthplace. Qualitative data were analyzed using a previously developed deductive coding framework. RESULTS: In agreement with previous findings from Austria, positive experiences mainly addressed care experienced at an individual level (in particular healthcare practitioners' competence and personality traits) and suggested changes mainly addressed services at birthplace (issues related to infrastructure, information and counseling, and empowerment). Responses not initially included in the coding framework addressed aspects such as informal payment (in both countries), desire for home birth (particularly in Lithuania), or mistreatment of parturients (particularly in Romania). CONCLUSIONS: We conclude that similar trends in childbirth care exist in Lithuania and Romania with regard to parturients' personal experiences and psychosocial needs and that addressing the needs of parturients is important for improving service provision.

Prevalence and acceptability of psychological and/or economic intimate partner violence, and utilization of mental health services by its survivors in Lithuania.

BACKGROUND: Lithuania has one of the highest averages in the European Union when it comes to psychological and/or economic intimate partner violence (PE-IPV). IPV survivors are several times more likely to have mental health conditions than those without IPV experiences. The aim of this article is to study the prevalence, characteristics and attitudes of PE-IPV survivors in Lithuania, and the predictors of them accessing mental health services. METHODS: A cross-sectional study based on a national survey representative of the adult population. The survey was implemented by a third-party independent market research company employing an online survey panel. Logistic regression models were used in the analysis. RESULTS: Almost 50% of women in Lithuania experience PE-IPV. Females are significantly more likely to experience it than males. The vast majority of women find PE-IPV unacceptable; however, only one-third of survivors seek any type of help. Only one-tenth approach mental health services, with divorcees being at higher odds of doing so. CONCLUSIONS: Further research is needed to explore predictors and contextual factors of why IPV survivors seek mental healthcare, or not. Policy implications include the need to eliminate IPV and mental health stigma; develop accessible mental health services and effective treatment approaches.

Longitudinal association of grip strength with cardiovascular and all-cause mortality in older urban Lithuanian population.

BACKGROUND: Ageing populations experience greater risks associated with health and survival. It increases the relevance of identifying variables associated with mortality. Grip strength (GS) has been identified as an important biomarker for all cause and cardiovascular mortality, however, its prognostic value has not been studied in Lithuania. The aim of the present study is to evaluate the relationship of GS to vital status in a representative sample of the Lithuanian 45-72-year-old urban population during the period of 12 years of follow-up and to explore associations of GS with all-cause mortality and mortality from cardiovascular diseases (CVD). METHODS: Within the framework of the international study Health, Alcohol and Psychosocial Factors in Eastern Europe (HAPIEE) 7,115 men and women 45-72 years of age were examined in the baseline survey (2006 to 2008). Data from the Official Lithuanian Mortality Register were used to evaluate CVD and all-cause mortality from follow-up till 2020. Cox proportional hazards regression was used, and four models for all-cause and CVD mortality were assessed. RESULTS: The mean GS was significantly higher among survivors' men and women as compared to individuals deceased from CVD and other causes of death. In survivor men and women groups, minimal values of GS in all terciles were higher as compared to all three deceased groups. In both men and women groups, the lowest GS (1st tercile) was associated with a significantly higher risk of all-cause and CVD mortality as compared to the highest levels of GS (3rd tercile) in three Cox regression models. In both men and women were found to have a 1.34- and 1.35-fold higher risk of all-cause mortality, respectively, at lower GS, but no significant difference in the risk of CVD mortality. When GS was treated in all models as decrement per 1 kg and decrement per 1 SD, in both men and women, the risk of all-cause mortality significantly increased with decreasing of GS. CONCLUSIONS: The mean GS was significantly higher among survivors' men and women as compared to deceased from CVD and other causes of death. Risk of all-cause mortality significantly increased with decreasing of GS.

Trends of alcohol-attributable deaths in Lithuania 2001-2021: epidemiology and policy conclusions.

BACKGROUND: Lithuania, a Baltic country in the European Union, can be characterized by high alcohol consumption and attributable burden. The aim of this contribution is to estimate the mortality burden due to alcohol use for the past two decades based on different relative risk functions, identify trends, and analyse the associations of alcohol-attributable burden with alcohol control policies and life expectancy. METHODS: The standard methodology used by the World Health Organization for estimating alcohol-attributable mortality was employed to generate mortality rates for alcohol-attributable mortality, standardized for Lithuania's 2021 population distribution. Joinpoint analysis, T-tests, correlations, and regression analyses including meta-regressions were used to describe trends and associations. RESULTS: Age-standardized alcohol-attributable mortality was high in Lithuania during the two decades between 2001 and 2021, irrespective of which relative risks were used for the estimates. Overall, there was a downward trend, mainly in males, which was associated with four years of intensive implementation of alcohol control policies in 2008, 2009, 2017, and 2018. For the remaining years, the rates of alcohol-attributable mortality were stagnant. Among males, the correlations between alcohol-attributable mortality and life expectancy were 0.90 and 0.76 for Russian and global relative risks respectively, and regression analyses indicated a significant association between changes in alcohol-attributable mortality and life expectancy, after controlling for gross domestic product. CONCLUSIONS: Male mortality and life expectancy in Lithuania were closely linked to alcohol-attributable mortality and markedly associated with strong alcohol control policies. Further implementation of such policies is predicted to lead to further improvements in life expectancy.

Hepatitis C screening in Lithuania: first-year results and scenarios for achieving WHO elimination targets.

BACKGROUND: The World Health Organization (WHO) has outlined a set of targets to achieve eliminating hepatitis C by 2030. In May 2022, Lithuanian health authorities initiated a hepatitis C virus (HCV) screening program to start working towards elimination. In the program, bonus was given to general practitioners (GPs) to promote and conduct anti-HCV tests for two situations: (1) one time testing for individuals born in 1945-1994 and (2) annual HCV testing for persons who inject drugs or are living with human immunodeficiency virus (HIV) regardless of age. This study aimed to model the current viral hepatitis C epidemiological status in Lithuania and to outline the requirements for WHO elimination targets using the first-year HCV screening results. METHODS: Individuals were invited to participate in the anti-HCV screening by GPs during routine visits. Patients who tested positive were then referred to a gastroenterologist or infectious disease doctor for further confirmatory testing. If a patient received a positive RNA test and a fibrosis staging result of ≥ F2, the doctor prescribed direct-acting antivirals. Information on the patients screened, diagnosed, and treated was obtained from the National Health Insurance Fund. The Markov disease progression model, developed by the CDA Foundation, was used to evaluate the screening program results and HCV elimination progress in Lithuania. RESULTS: Between May 2022 and April 2023, 790,070 individuals underwent anti-HCV testing, with 11,943 individuals (1.5%) receiving positive results. Anti-HCV seroprevalence was found to be higher among males than females, 1.9% and 1.2%, respectively. Within the risk population tested, 2087 (31.1%) seropositive individuals were identified. When comparing the screening program results to WHO elimination targets through modelling, 2180 patients still need to be treated annually until 2030, along with expanding fibrosis restrictions. If an elimination approach was implemented, 1000 new infections would be prevented, while saving 150 lives and averting 90 decompensated cirrhosis cases and 110 hepatocellular carcinoma cases. CONCLUSIONS: During the first year of the Lithuanian screening program, GPs were able to screen 44% of the target population. However, the country will not meet elimination targets as it currently stands without increasing treatment levels and lifting fibrosis restrictions.

Impact of health spending on hospitalization rates in Baltic countries: a comparative analysis.

INTRODUCTION: This study examines the association between healthcare indicators and hospitalization rates in three high-income European countries, namely Estonia, Latvia, and Lithuania, from 2015 to 2020. METHOD: We used a sex-stratified generalized additive model (GAM) to investigate the impact of select healthcare indicators on hospitalization rates, adjusted by general economic status-i.e., gross domestic product (GDP) per capita. RESULTS: Our findings indicate a consistent decline in hospitalization rates over time for all three countries. The proportion of health expenditure spent on hospitals, the number of physicians and nurses, and hospital beds were not statistically significantly associated with hospitalization rates. However, changes in the number of employed medical doctors per 10,000 population were statistically significantly associated with changes of hospitalization rates in the same direction, with the effect being stronger for males. Additionally, higher GDP per capita was associated with increased hospitalization rates for both males and females in all three countries and in all models. CONCLUSIONS: The relationship between healthcare spending and declining hospitalization rates was not statistically significant, suggesting that the healthcare systems may be shifting towards primary care, outpatient care, and on prevention efforts.

Disposition of improving quality of life in older adults: the case of Lithuania.

BACKGROUND: Quality of life is a phenomenon that recently required lots of concern, especially for older adults, since healthy aging and longevity have become the focus in life. Most research on the quality of life addresses certain issues of older people having special diseases, health problems, and disorders. Our research is based on holistic quality of life empowering multiple areas of life/domains of older adults without addressing their diseases or health disorders. AIM: Our research aims at evaluating the quality of life of the research participants (older people), addressing their problematic areas and suggestions for better quality of life. METHODS: The conducted research implied mixed methods as quantitative survey and reflection based on interviews. We chose participants from the III age university and the ongoing project "Healthy Aging Program". RESULTS: The research results showed the lowest ratings for emotional and physical health and the highest rating for social health. Also, older adults tend to avoid specifying precise measures to improve their quality of life and demonstrate a more conservative stance regarding the implementation of more radical changes in improving water consumption, exercising, meal planning, and enhancing psychosocial well-being. CONCLUSIONS: The overall quality of life rating was lower than the average. Older adults are not sufficiently prepared or educated to make significant changes to develop healthier habits in their quality-of-life improvement, though, they demonstrate concern about their quality of life.

Diversity of fungus-like stramenopilous organisms (Oomycota) in Lithuanian freshwater aquaculture: Morphological and molecular analysis, risk to fish health.

The present work is the first comprehensive study of fungus-like stramenopilous organisms (Oomycota) diversity in Lithuanian fish farms aimed at proper identification of saprolegniasis pathogens, which is important for water quality control, monitoring infection levels and choosing more effective treatments for this disease in aquaculture. Pathogenic to fish, Saprolegnia and other potentially pathogenic water moulds were isolated from adult fish, their eggs, fry and from water samples. All detected isolates were examined morphologically and confirmed by sequence-based molecular methods. A total of eight species belonging to the genera Saprolegnia, Achlya, Newbya and Pythium were identified. Four species (S. parasitica, S. ferax, S. australis and S. diclina) were found to be the main causative agents of saprolegniasis in Lithuania. S. parasitica and S. ferax dominated both in hatcheries and open fishponds, accounting for 66.2% of all isolates. S. parasitica was isolated from all farmed salmonid fish species as well as from the skin of Cyprinus carpio, Carassius carassius and Perca fluviatilis. S. australis was isolated from water and once from the skin of Oncorhynchus mykiss, and S. diclina was detected only once on the skin of Salmo salar fish. In addition, Achlya ambisexualis, Saprolegnia anisospora and Newbia oligocantha isolated during this study are noted as a possible source of saprolegniasis. The results of this study are relevant for assessing the risk of potential outbreaks of saprolegniasis or other saprolegnia-like infection in Lithuanian freshwater aquaculture.

Diversity of Sarcocystis parasites in southeastern Baltic Sea catchment ecosystems.

Currently, research on apicomplexan Sarcocystis parasites is mainly carried out by analyzing animal carcasses. However, environmental studies would not only allow faster detection of possible sources of infection but also avoid the use of animals for investigations. Therefore, in the current study, we aimed to identify tested Sarcocystis species in sediment collected from water bodies located in the southeastern Baltic countries. A total of 99 sediment samples were collected during the summer from different types of water bodies in Estonia, Latvia, Lithuania, and Poland. Species-specific nested PCR targeting cox1 gene was used for the detection of selected Sarcocystis species (S. cruzi, S. bovifelis, S. hirsuta, S. arieticanis, S. tenella, S. capracanis, S. miescheriana, and S. bertrami) infecting livestock. The results showed a statistically lower (p < 0.05) occurrence of Sarcocystis parasites in Estonia (50%) compared to three countries, where the detection rate of Sarcocystis spp. DNA was remarkably higher, ranging from 88 to 100%. Among Sarcocystis species tested, S. cruzi (83.8%) and S. arieticanis (55.6%) using cattle and sheep as their intermediate hosts were most commonly identified. The detection rates of some of the analyzed Sarcocystis species were significantly different in southeastern Baltic countries. It is discussed that the detection rates of certain Sarcocystis species depend not only on the number of animals per 1 km2 but also on various ecological factors and farming practices that differ in the amount of contact domestic animals have with predators and the potential for animals to become infected through natural water or food sources.

Emergence of OXA-48-producing Klebsiella pneumoniae in Lithuania, 2023: a multi-cluster, multi-hospital outbreak.

In 2023, an increase of OXA-48-producing Klebsiella pneumoniae was noticed by the Lithuanian National Public Health Surveillance Laboratory. Whole genome sequencing (WGS) of 106 OXA-48-producing K. pneumoniae isolates revealed three distinct clusters of carbapenemase-producing K. pneumoniae high-risk clones, including sequence type (ST) 45 (n = 35 isolates), ST392 (n = 32) and ST395 (n = 28), involving six, six and nine hospitals in different regions, respectively. These results enabled targeted investigation and control, and underscore the value of national WGS-based surveillance for antimicrobial resistance.

Responding to the needs of survivors of intimate partner violence in Lithuania: perceptions of mental health and social care professionals.

Around eight-out-of-ten survivors of domestic violence in Lithuania are women, and of those, eight-out-of-ten suffer violence specifically from their intimate partners (IPV). Women who experience IPV are at higher risk of having mental health conditions. This study aims to explore the perspectives of mental health and social care professionals regarding the provision of mental health support to IPV survivors in Lithuania. Four focus groups were conducted among 29 service providers from across the country. Audio-recordings were transcribed verbatim and analyzed thematically using MAXQDA software. The five main themes derived from the analysis reveal: 1) low levels of IPV awareness among IPV survivors who seek support with their mental health; 2) a lack of specialized training among professionals as a barrier to effective support; 3) a low prioritization on the national level; 4) little inter-sectoral collaboration which undermines the complexity of needed responses; 5) broader systemic problems. The provision of mental health support to IPV survivors lacks the recognition that IPV is gender-based violence and a major public (mental) health problem. The complexity of needed services is absent. Further research needs to explore the utilization of mental health services by IPV survivors and their perceptions concerning it.

Predictors of children's headaches during the second COVID-19 pandemic wave in the country with long-lasting lockdown.

OBJECTIVES: The current study examined the links and interactions among headaches, screen-based media use, physical activity, sleep, and the family environment in Lithuanian school-aged children during the second COVID-19 lockdown. METHODS: The study comprised data of 541 children aged 7-14 years from different Lithuania regions, and without chronic health conditions or developmental disorders. Information about the child was provided by their parents or caregivers who filled questionnaire on child's screen time, sleep duration and quality, physical activity, parental distress, parent-child relationship, history of child's headaches and infectious diseases. RESULTS: During the study period, 54% of the children had headaches, and the frequency was positively associated with child's age, screen time and parental distress, as well as negatively related to physical activity (PA), sleep quality, and the parent-child relationship. Parental education was related to child's PA, screen time and sleep quality. The results of binary logistic regression analysis and path analysis revealed that sleep quality and parental distress were significant predictors of headaches in children. CONCLUSIONS: Family and child or adolescent education and lifestyle modification aiming to improve sleep hygiene and PA, and to reduce screen-based sedentary behaviour should be provided. Family centred approach for more effective coping with distress and improvement of parent-child relationship is also important in treating child and adolescent headache.

Exploring the abundance and characteristics of litter in Lithuanian riversides: a citizen science approach.

To gain a better understanding of the sources and ecological effects of plastic contamination in Lithuanian rivers, as well as to provide guidance for mitigation, monitoring is necessary. This is a logistically and financially demanding endeavor, particularly in the case of microplastics. Citizen science provides a viable option for sampling sites that are accessible, thus enabling the monitoring of wide areas. In Lithuania, a citizen science approach was employed, with schoolchildren examining litter at riversides and identifying potential sources at 24 sampling sites in Autumn 2022 and 32 in Spring 2023, covering both large and small rivers. The maximum amount of 220 items per location was registered in Autumn 2022, whereas 111 items per location were registered in Spring 2023. The two main types of microlitter discovered were plastic (34-42%) and cigarette butts (17-22%), with glass, paper, and metal also present, which suggests that recreational visitors are the main source of litter. By K-means clustering analysis, all locations were divided into four clusters according to litter composition. To sum up, the findings of this study illustrate the importance of citizen science in providing insight into the contamination of Lithuanian rivers, which can be used to inform the development of conservation strategies.

Cross-Cultural Adaptation and Measurement of Psychometric Properties of the Lithuanian Version of the Western Ontario Shoulder Instability Index (WOSI).

Background and Objectives: The Western Ontario Shoulder Instability Index (WOSI) is a disease-specific self-administered questionnaire which is designed to measure health-related quality of life for patients with shoulder instability. The objective of this study was to translate and adapt the WOSI questionnaire for the Lithuanian-speaking population and investigate the psychometric properties of the Lithuanian version of the WOSI questionnaire (WOSI-LT): validity, reliability, and responsiveness. Materials and Methods: The WOSI scale was translated into Lithuanian using D. E. Beaton's systematic and standardized guidelines for cross-cultural adaptation of patient-administered scales. Subsequently, the psychometric properties of the Lithuanian version of the scale (WOSI-LT) were investigated. The study involved 40 patients who reported shoulder instability and underwent surgical treatment. All patients completed the WOSI-LT, QuickDASH, and SF-12 scales. A subset of 10 patients was selected for the reproducibility and responsiveness evaluation. Based on the obtained data, the reliability, validity, and responsiveness of WOSI-LT were examined using statistical analysis methods. Results: The Lithuanian adaptation of the WOSI questionnaire exhibited a high degree of internal consistency, evidenced by a Cronbach's alpha of 0.93. Its reproducibility was commendable with an intraclass correlation coefficient (ICC) value of 0.90. When assessing correlations, WOSI-LT demonstrated a stronger relationship with QuickDASH (r = 0.64) than with SF-12 (physical component score (PCS) 0.61, mental component score (MCS) 0.33). Six months post-operation, the responsiveness of the WOSI-LT was particularly notable, with a standardized response mean (SRM) of 0.91, the highest among the three scales. Furthermore, no floor or ceiling effects were identified in the scores of the Lithuanian WOSI. Conclusions: WOSI-LT is a valid, reliable, and responsive questionnaire that correlates excellently with the original English version of the scale. This scale can be used in Lithuanian medical institutions to assess the severity of patients' shoulder instability and evaluate their progress during treatment.
