Physical Activity Evaluation Using Activity Trackers for Type 2 Diabetes Prevention in Patients with Prediabetes.

BACKGROUND: Prediabetes is a reversible condition, but lifestyle-changing measures, such as increasing physical activity, should be taken. This article explores the use of Fitbit activity trackers to assess physical activity and its impact on prediabetic patient health. METHODS: Intervention study. In total, 30 volunteers (9 males and 21 females), aged 32-65 years, with impaired glucose levels and without diabetes or moving disorders, received Fitbit Inspire activity trackers and physical activity recommendations. A routine blood check was taken during the first and second visits, and body composition was analyzed. Physical activity variability in time was assessed using a Poincare plot. RESULTS: The count of steps per day and variability differed between patients and during the research period, but the change in total physical activity was not statistically significant. Significant positive correlations between changes in lipid values, body mass composition, and variability of steps count, distance, and minutes of very active physical activity were observed. CONCLUSIONS: When assessing physical activity, data doctors should evaluate not just the totals or the medians of the steps count, but also physical activity variability in time. The study shows that most changes were better linked to the physical activity variability than the total count of physical activity.

Epidemiology of Chronic Obstructive Pulmonary Disease (COPD) Comorbidities in Lithuanian National Database: A Cluster Analysis.

Various comorbidities and multimorbidity frequently occur in chronic obstructive pulmonary disease (COPD), leading to the overload of health care systems and increased mortality. We aimed to assess the impact of COPD on the probability and clustering of comorbidities. The cross-sectional analysis of the nationwide Lithuanian database was performed based on the entries of the codes of chronic diseases. COPD was defined on the code J44.8 entry and six-month consumption of bronchodilators. Descriptive statistics and odds ratios (ORs) for associations and agglomerative hierarchical clustering were carried out. 321,297 patients aged 40-79 years were included; 4834 of them had COPD. A significantly higher prevalence of cardiovascular diseases (CVD), lung cancer, kidney diseases, and the association of COPD with six-fold higher odds of lung cancer (OR 6.66; p < 0.0001), a two-fold of heart failure (OR 2.61; p < 0.0001), and CVD (OR 1.83; p < 0.0001) was found. Six clusters in COPD males and five in females were pointed out, in patients without COPD-five and four clusters accordingly. The most prevalent cardiovascular cluster had no significant difference according to sex or COPD presence, but a different linkage of dyslipidemia was found. The study raises the need to elaborate adjusted multimorbidity case management and screening tools enabling better outcomes.

Research on physical activity variability and changes of metabolic profile in patients with prediabetes using Fitbit activity trackers data.

BACKGROUND: Monitoring physical activity with consumers wearables is one of the possibilities to control a patient's self-care and adherence to recommendations. However, clinically approved methods, software, and data analysis technologies to collect data and make it suitable for practical use for patient care are still lacking. OBJECTIVE: This study aimed to analyze the potential of patient physical activity monitoring using Fitbit physical activity trackers and find solutions for possible implementation in the health care routine. METHODS: Thirty patients with impaired fasting glycemia were randomly selected and participated for 6 months. Physical activity variability was evaluated and parameters were calculated using data from Fitbit Inspire devices. RESULTS: Changes in parameters were found and correlation between clinical data (HbA1c, lipids) and physical activity variability were assessed. Better correlation with variability than with body composition changes shows the potential to include nonlinear variability parameters analysing physical activity using mobile devices. Less expressed variability shows better relationship with control of prediabetic and lipid parameters. CONCLUSIONS: Evaluation of physical activity variability is essential for patient health, and these methods used to calculate it is an effective way to analyze big data from wearable devices in future trials.

SARS-CoV-2 Seroprevalence in Lithuania: Results of National Population Survey.

SUMMARY BACKGROUND: Betacoronavirus SARS-CoV-2 has spread in early 2020 worldwide just in several months. The official statistics are consistently collected, but this is mainly based on symptomatic reports. This study was aimed to estimate the seroprevalence of SARS-CoV-2 infection in Lithuanian population. MATERIALS AND METHODS: Study was conducted during August-September 2020 in 6 municipalities of Lithuania. The sample comprised 3087 adult participants from the general population (mean age 53.7 years, 64% female). SARS-CoV-2 antibodies were assessed using AMP IgM/IgG Rapid Test, other data were based on self-report. Seroprevalence was assessed as a crude estimate and as adjusted by sensitivity-specificity of the test. RESULTS: The crude seroprevalence in the total sample was 1.9%, the adjusted - 1.4%, ranging from 0.8% to 2.4% across municipalities. Among seroprevalent cases, 67.2% had IgG, 29.3% had IgM, and 3.5% had both IgG and IgM. An increased risk for seropositive test was observed among people who reported having had close contacts with SARS-CoV-2 positives (OR=5.49, p<0.001). At the borderline significance were female gender (OR=1.75, p=0.082) and non-smoking status (OR=2.95, p=0.072). Among the seropositive participants, 69.0% reported having had no COVID-19 symptoms since 1 March 2020, while 31.0% reported having had at least one of the symptoms. CONCLUSIONS: The SARS-CoV-2 seroprevalence in Lithuanian sample in August-September 2020 was 1.4%, ranging from 0.8% to 2.4% across municipalities. Given the overall official data, by the end of study (11 September 2020) the total COVID-19 rate in Lithuania was 117.5 per 100,000 population or 0.12%. This suggests more than 10 times higher prevalence of virus across the population than the official estimates.

Follow-Up Analysis of Pulmonary Function, Exercise Capacity, Radiological Changes, and Quality of Life Two Months after Recovery from SARS-CoV-2 Pneumonia.

Background and objective: According to the World Health Organization (WHO), more than 100 million people have already recovered from SARS-CoV-2 infection. Therefore, it is imperative to understand the possible outcomes of COVID-19. The aim of our study was to evaluate pulmonary function, exercise capacity, residual radiological changes, and health-related quality of life (HRQoL) at follow-up in a cohort of SARS-CoV-2 pneumonia survivors. Materials and Methods: Patients with SARS-CoV-2 infection and radiologically confirmed lung injury, with no chronic lung disease prior to this infection, were included in the study. Patients' evaluation 2 months after their discharge from hospital included spirometry (FVC, FEV1, FEV1/FVC), determination of lung volume (TLC, VC, RV) and diffusing capacity of lung for carbon monoxide (DLCO, adjusted for hemoglobin), 6-Minute Walk Test (6MWT), chest CT scan, and 36-Item Short Form General Health Survey (SF-36). Results: Fifty-one patients (25 men, 26 women) were included. The mean age was 56 years (SD-11,72). Eighteen patients (35.3%) had experienced moderate COVID-19, 21 (41.2%) severe COVID-19, and 12 (23.5%) were critically ill. The mean follow-up visit time after the discharge from hospital was 60 days (SD-17). Pulmonary function at follow-up was impaired in 24 (47.2%) patients. Reduced lung volume was observed in 15 (29.4%) patients, DLCO reduction in 15 (29.4%) patients, and only one patient displayed obstruction. Twelve patients out of 51 (12/51, 27.3%) showed reduced physical capacity in the 6 MWT, and 3/51 (9.1%) showed desaturation, with SO2 < 90%. Different levels of abnormality were found in 49/51 (96,1%) patients on follow-up chest CT; the median radiological score was 10.9 (SD ± 8.87, possible maximal score, 25). Ground-glass opacity was the most common radiological feature, found in 45 (88.2%) patients. The SF-36 scores demonstrated a reduction in health status across all domains, with the lowest scores for limitations in social activities because of physical problems, vitality, and general health. Conclusion: In the group of COVID-19 pneumonia survivors 2 months after hospital discharge, residual changes in the lungs on chest CT and in lung function and reduced physical and HRQoL status were found in a significant number of patients. To evaluate COVID-19 long-term consequences, a longer follow-up period is needed.

Structure and Distribution of Health Care Costs across Age Groups of Patients with Multimorbidity in Lithuania.

BACKGROUND: Patients with multimorbidity account for ever-increasing healthcare resource usage and are often summarised as big spenders. Comprehensive analysis of health care resource usage in different age groups in patients with at least two non-communicable diseases is still scarce, limiting the quality of health care management decisions, which are often backed by limited, small-scale database analysis. The health care system in Lithuania is based on mandatory social health insurance and is covered by the National Health Insurance Fund. Based on a national Health Insurance database. The study aimed to explore the distribution, change, and interrelationships of health care costs across the age groups of patients with multimorbidity, suggesting different priorities at different age groups. METHOD: The study identified all adults with at least one chronic disease when any health care services were used over a three-year period between 2012 and 2014. Further data analysis excluded patients with single chronic conditions and further analysed patients with multimorbidity, accounting for increasing resource usage. The costs of primary, outpatient health care services; hospitalizations; reimbursed and paid out-of-pocket medications were analysed in eight age groups starting at 18 and up to 85 years and over. RESULTS: The study identified a total of 428,430 adults in Lithuania with at least two different chronic diseases from the 32 chronic disease list. Out of the total expenditure within the group, 51.54% of the expenses were consumed for inpatient treatment, 30.90% for reimbursed medications. Across different age groups of patients with multimorbidity in Lithuania, 60% of the total cost is attributed to the age group of 65-84 years. The share in the total spending was the highest in the 75-84 years age group amounting to 29.53% of the overall expenditure, with an increase in hospitalization and a decrease in outpatient services. A decrease in health care expenses per capita in patients with multimorbidity after 85 years of age was observed. CONCLUSIONS: The highest proportion of health care expenses in patients with multimorbidity relates to hospitalization and reimbursed medications, increasing with age, but varies through different services. The study identifies the need to personalise the care of patients with multimorbidity in the primary-outpatient setting, aiming to reduce hospitalizations with proactive disease management.

Mitigating arrhythmia risk in Hydroxychloroquine and Azithromycin treated COVID-19 patients using arrhythmia risk management plan.

AIMS: To assess cardiac safety in COVID-19 patients treated with the combination of Hydroxychloroquine and Azithromycin using arrhythmia risk management plan. METHODS AND RESULTS: We retrospectively examined arrhythmia safety of treatment with Hydroxychloroquine and Azithromycin in the setting of pre-defined arrhythmia risk management plan. The data was analyzed using R statistical package version 4.0.0. A two-tailed p-value<0.05 was considered significant. 81 patients were included from March 23rd to May 10th 2020. The median age was 59 years, 58.0% were female. The majority of the study population (82.7%) had comorbidities, 98.8% had radiological signs of pneumonia. Fourteen patients (17.3%) experienced QTc ≥ 480 ms and 16 patients (19.8%) had an increase of QTc ≥ 60 ms. Seven patients (8.6%) had QTc prolongation of ≥ 500 ms. The treatment was discontinued in 4 patients (4.9%). None of the patients developed ventricular tachycardia. The risk factors significantly associated with QTc ≥ 500 ms were hypokalemia (p = 0.032) and use of diuretics during the treatment (p = 0.020). Three patients (3.7%) died, the cause of death was bacterial superinfection with septic shock in two patients, and disseminated intravascular coagulation with multiple organ failure in one patient. None of these deaths were associated with cardiac arrhythmias. CONCLUSION: We recorded a low incidence of QTc prolongation ≥ 500 ms and no ventricular tachycardia events in COVID-19 patients treated with Hydroxychloroquine and Azithromycin using cardiac arrhythmia risk management plan.

Management of Patients with Coronary Artery Disease in Lithuania: a Comparison with Other Central Eastern European Countries Based on Data From the International CLARIFY Registry.

INTRODUCTION: Lithuania has one of the highest mortality rates from coronary heart disease (CHD) among European countries. Most CHD are preventable, but when they occur, the management of these patients is important in secondary prevention. The purpose of the present analysis was to describe the demographics, clinical profile, and contemporary management of patients with stable CHD in the Lithuanian population and to compare data with other Central Eastern European countries. METHODS: CLARIFY (prospective observational longitudinal registry of patients with stable CHD) is an international cohort study in outpatients with stable CHD. Treated outpatients with established CHD from the CLARIFY registry in Lithuania (214 patients) were compared with those from the rest of Central Eastern Europe (2794 patients). RESULTS: Lithuanian patients were younger (p = 0.0275), had a higher body mass index (p = 0.0003), and more frequently received treatment for hypertension (p < 0.0001). Prevalence of dyslipidemia (p < 0.0001) was higher in Lithuanian patients but a smaller group of people had diabetes (p < 0.0001). The total cholesterol (p < 0.0001), low-density lipoprotein cholesterol (p < 0.0001), and blood pressure (p < 0.0001) were higher in the Lithuanian population. A smaller proportion of Lithuanian patients were physically inactive, and the majority of patients in Lithuania were engaged in light physical activity compared with Central Eastern European patients (p = 0.0018). CONCLUSION: The data analysis shows that management of hypertension, dyslipidemia, smoking, and obesity in patients with CHD in Lithuania is insufficient and needs further improvement.

Type 2 diabetes mellitus [Lithuania has one of the highest mortality rates from cardiovascular disease (CVD) among European countries. The purpose of the present analysis was to describe the demographics, clinical profile, and contemporary management of patients with stable CVD in the Lithuanian population and to compare data with other Central Eastern European countries. Our data shows that management of elevated blood pressure, abnormal amounts of lipids, smoking, and excessive weight in Lithuanian patients with CVD is insufficient compared with the rest of Central Eastern Europe and needs further improvement].

Trends in cardiovascular risk factor prevalence among Lithuanian middle-aged adults between 2009 and 2018.

BACKGROUND AND AIMS: The aim of the study was to estimate trends and differences in cardiovascular disease (CVD) risk factor prevalence among middle-aged men and women based on the data from the Lithuanian High Cardiovascular Risk (LitHiR) primary prevention program between 2009 and 2018. METHODS: A community-based cross-sectional study included men aged 40-54 years and women aged 50-64 years without overt CVD. Nationally representative data comprised 110,370 Lithuanian adults (42.4% men and 57.6% women) examined in the period 2009-2018. Prevalences of major CVD risk factors, such as dyslipidaemia, arterial hypertension, diabetes mellitus, obesity, metabolic syndrome and smoking, were assessed. RESULTS: The study showed a significant drop in the prevalence of dyslipidaemia and TC levels among men (p = 0.030 and p < 0.001) and no significant change among women (p = 0.594 and p = 0.799). The prevalence of AH significantly decreased in both gender groups (p < 0.001 in women and p < 0.001 in men). Obesity rates declined among women while it remained constant among men (p < 0.001 and p = 0.100 respectively). There was a significant decline among women and a significant increase among men in the prevalence of metabolic syndrome (p < 0.001 and p = 0.016 respectively). The prevalence of diabetes increased until 2013, after which it started decreasing in the whole group (p = 0.005). The study showed a significant increase in the percentage of smoking women (p < 0.001), although the number of smoking men remained much higher (about 40%) (p < 0.001). CONCLUSIONS: In our observational study, we have documented a high prevalence of all CVD risk factors in 2009 with a slight decrease during the period in most prevalence rates, except in dyslipidaemia and smoking levels.

Daily Heart Rate Variability Indices in Subjects with and Without Metabolic Syndrome Before and After the Elimination of the Influence of Day-Time Physical Activity.

Background and Objectives: The available research shows conflicting data on the heart rate variability (HRV) in metabolic syndrome (MetS) subjects. The discrepancy suggests a methodical shortcoming: due to the influence of physical activity, the standard measuring of HRV at rest is not comparable with HRV assessment based on 24h Holter monitoring, which is preferred because of its comprehensiveness. To obtain a more reliable measure and to clarify to what extent HRV is altered in MetS, we assessed a 24h HRV before and after the elimination of the influence of physical activity. Materials and Methods: We investigated 69 metabolic syndrome (MetS) and 37 control subjects, aged 50-55. In all subjects, 24h monitoring of electrocardiogram, blood pressure, and actigraphy profiles were conducted. To eliminate the influence of day-time physical activity on RR intervals (RRI), a linear polynomial autoregressive model with exogenous terms (ARX) was used. Standard spectral RRI analysis was performed. Results: Subjects with MetS had blunted HRV; the diurnal SDNN index was reliably lower in the MetS group than in control subjects. The elimination of the influence of physical activity did not reveal a significant HRV change in long-term indices (SDNN, SDANN, and SD2), whilst adjacent RRI values (RMSSD, pNN50, and SD1) and SDNN index significantly increased (p < 0.001). An increase in the latter indices highlighted the HRV difference between the MetS and control groups; a significant (p < 0.001) decrease of all short-term HRV variables was found in the MetS group (p < 0.01), and low-frequency spectral components were less pronounced in the MetS group. Conclusion: The application of a polynomial autoregressive model in 24h HRV assessment allowed for the exclusion of the influence of physical activity and revealed that MetS is associated with blunted HRV, which reflects mitigated parasympathetic tone.

Diagnosing COPD in primary care: what has real life practice got to do with guidelines?

BACKGROUND: The role of primary care physician in COPD management varies in different health care systems. According to the researches in various countries, extent of spirometry use in diagnosing and grading COPD frequently remains insufficient. Inaccurate diagnosis results in mistreatment and disease progression.The aims of our study were to investigate the accuracy of COPD diagnosis, grading, and treatment according to guidelines in daily practice of primary care. METHODS: A retrospective analysis of ambulatory records in a large primary care center was conducted. Digital medical records of current patients were screened for ICD-10-AM codes J44.0, J44.1, J44.8 and J44.9. All medical records starting from the first visit in this primary care center were reviewed. RESULTS: Two hundred twenty-eight patients diagnosed with COPD were included in the study, 118 male, mean age 67 yrs. (SD 14). A spirometry report was available to 58% of the patients, 75% of them met the guidelines for COPD diagnosis. The grade was correct for 56.8% of the patients. 54% were consulted by the pulmonologist at least once. After re-analyzing spirometry, correcting the diagnosis, and grading, it was determined that only 70% of the patients were receiving appropriate treatments. Sixteen per cent of patients were undertreated and 14% were overtreated. CONCLUSIONS: COPD care in primary practice remains suboptimal. Incorrect approach often leads to incorrect grading and mistreatment. Points for improvement should be identified in further studies.

Is the coronary artery calcium score the first-line tool for investigating patients with severe hypercholesterolemia?

BACKGROUND: Coronary artery calcium (CAC) is known as a reliable tool for estimating risk of myocardial infarction, coronary death, all-cause mortality and is even used to evaluate suitable asymptomatic patients. We therefore aimed to evaluate whether CAC scoring can be applied in the algorithm for clinical examination of patients with severe hypercholesterolemia (SH). METHODS: During the period of 2016-2017 a total of 213 asymptomatic adults, underwent computed tomography angiography to evaluate their CAC scoring. The sample consisted of 110 patients with SH and 103 age and sex matched controls without dyslipidemia and established cardiovascular disease. RESULTS: In total there were 79 (37.2%) subjects with elevated (≥25th) CAC percentiles. Out of them 47 (59.5%) had SH and 32 (40.5%) did not. CAC score did not differ between groups (SH (+) 140.30 ± 185.72 vs SH (-) 87.84 ± 140.65, p = 0.146), however there was a comparable difference in how the participants of these groups distributed among different percentile groups (p = 0.044). Gender, blood pressure, tabaco use, physical activity, family history of coronary artery disease and diabetes mellitus were not associated with CAC score (p > 0.05). There were no significant correlations between biochemical parameters and CAC percentiles except for increase in lipoprotein(a) (p = 0.038). Achilles tendon pathology, visceral obesity, body mass index and increased waist-hip ratio were not associated with CAC percentiles either (p > 0.05). CONCLUSIONS: CAC score is not associated with presence of SH. CAC score is not an appropriate diagnostic tool in the algorithm for clinical examination of patients with SH. Further larger studies are needed to support our findings.

Natural killer cell-based immunotherapy: a new fighter against melanoma?

Changes in the expression of proteins on cancer cell surface are a typical outcome of malignant transformation. Natural killers (NKs) utilize a set of activating and inhibitory receptors that enable them to recognize altered protein expression and then destroy 'stressed' cells such as cancer or virus-infected cells. Major histocompatibility complex class I polypeptide-related sequence A and B (MICA and MICB, respectively) are expressed by various human tumors and can be recognized by activating NK cell receptor NKG2D. However, cancer frequently escapes recognition by NK cells by proteolytic shedding of MICA and MICB proteins. A study carried out by Ferrari de Andrade and colleagues showed that monoclonal antibody targeting the site of proteolytic shedding of MICA and MICB reduced the progression of melanoma in immunocompromised and immune competent mice models by activation of NKG2D. This approach prevented the reduction of essential immunostimulatory ligands (MICA/MICB) and restored NK cell-driven anticancer immunity.

Cardiovascular risk assessment of dyslipidemic middle-aged adults without overt cardiovascular disease over the period of 2009-2016 in Lithuania.

BACKGROUND: Cardiovascular mortality in Lithuania is extremely high and abnormal lipid levels are very common among Lithuanian adults. Dyslipidemia is one of the main independent risk factors for cardiovascular diseases (CVD) leading to high absolute CVD risk. The aim of this study was to assess CVD risk in dyslipidemic middle-aged subjects. METHODS: During the period of 2009-2016 a total of 92,373 people (58.4% women and 41.6% men) were evaluated. This study included men aged 40-54 and women aged 50-64 without overt CVD. RESULTS: Any type of dyslipidemia was present in 89.7% of all study population. 7.5% of dyslipidemic patients did not have any other conventional risk factors. Three and more risk factors were detected in 60.1% of dyslipidemic subjects. All analyzed risk factors, except smoking, were more common in dyslipidemic adults compared to subjects without dyslipidemia: arterial hypertension (55.8% vs. 43.3%, p < 0.001), diabetes (11.1% vs. 7.3%, p < 0.001), abdominal obesity (45.3% vs. 30.2%, p < 0.001), BMI ≥30 kg/m2 (35.8% vs. 23.7%, p < 0.001), metabolic syndrome (34.0% vs. 9.2%, p < 0.001), family history of coronary heart disease (26.3% vs. 23.1%, p < 0.001), unbalanced diet (62.5% vs. 52.9%, p < 0.001) and insufficient physical activity (52.0% vs. 44.2%, p < 0.001). The prevalence of all evaluated risk factors, except smoking, increased with age. Average SCORE index was 1.87 in all study population, while dyslipidemic subjects had higher SCORE compared to control group (1.95 vs 1.20, p < 0.001). CONCLUSIONS: Almost two thirds of dyslipidemic middle-aged Lithuanian adults without overt cardiovascular disease had three or more other CVD risk factors, which synergistically increase absolute risk of CVD. The average 10-year risk of CVD death in patients with dyslipidemia was 1.95%. The importance of managing dyslipidemia as well as other risk factors in order to reduce burden of cardiovascular disease in Lithuania is evident.

Cardiovascular risk profile of patients with atherogenic dyslipidemia in middle age Lithuanian population.

BACKGROUND: Atherogenic dyslipidemia (AD) is a blood serum lipid profile abnormality characterized by elevation of triglycerides and reduced levels of high density lipoprotein cholesterol (HDL-C). It is associated with residual cardiovascular risk. This study evaluated and compared the risk profiles of patients with hypertriglyceridemia, low-HDL-C levels or AD, in order to understand, which lipid profile is associated with greater risk. METHODS: During the period of 2009-2016 a population of 92,373 Lithuanian adults (men 40-54 years old and women 50-64 years old) without overt cardiovascular disease were analyzed. Data of 25,746 patients (68.6% women and 31.4% men) with hypertriglyceridemia and/or low HDL-C low levels were collected and used for further statistical analysis. RESULTS: Participants with AD tend to have more unfavorable risk profile than participants with hypertriglyceridemia or low-HDL-C. AD tends to cluster with other atherogenic risk factors, such as arterial hypertension [odds ratio (OR) 1.96, 95% confidence intervals (CI) 1.87-2.01], smoking [OR 1.20, 95% CI 1.14-1.27], diabetes mellitus [OR 2.74, 95% CI 2.58-2.90], obesity [OR 2.92, 95% CI 2.78-3.10], metabolic syndrome [OR 22.27, 95% CI 20.69-23.97], unbalanced diet [OR 1,59, 95% CI 1.51-1.68], low physical activity [OR 1.80, 95% CI 1.71-1,89], CHD history in first degree relatives [OR 1.18, 95% CI 1.12-1.25] and total number of risk factors [OR 1.47, 95% CI 1.38-1.57]. CONCLUSION: AD is associated with more unfavorable cardiovascular risk profile than hypertriglyceridemia or low-HDL cholesterol levels. Once identified AD should require additional medical attention since it is an important factor of residual cardiovascular risk.

ADHD - the scourge of the 21st century? / ADHD ­ plaga XXI wieku?

Currently, attention deficit hyperactivity disorder (ADHD) is intensively studied by world medical community, its understanding expands, for example, it has now been diagnosed not only in children but also in adults. On the other hand, ADHD raises a number of discussions on the need of its treatment and, if there is a need, how it shall be treated, it is doubtful whether this disorder overall exists, because its "morphological component" has not been identified so far, and all the symptoms of ADHD, including anxiety, concentration difficulties, motor hyperactivity, cognitive disorders or social disadaptation, can be found in a number of mental disorders and somatic diseases. Modern attention, emotional and behavioral changes can be considered as a result of changing human social portrait. Those who question ADHD existence argue that this disorder is likely temperament and parenting matter, rather than the illness, and that the diagnosis and treatment of this illness can be a matter invented by doctors and pharmacists, the aim of which is to tame individuals disregarding public standards of conduct and get the maximum profit from medicines in the treatment of this illness. Due to the fact that ADHD is diagnosed more often, it is even called the twenty-first-century scourge. In this article we will review the historical aspect of formation of ADHD diagnosis, illness etiology, comorbidity with other mental and somatic diseases as well as treatment necessity and opportunities, paying attention to adult ADHD as well.

Patient satisfaction with primary healthcare services: are there any links with patients' symptoms of anxiety and depression?

BACKGROUND: The aim of our study was to determine the association of anxiety and depression symptoms, as well as the main socio-demographic factors, with patients' satisfaction with primary healthcare services. METHODS: The respondents were asked to fill out an anonymous questionnaire that included information on the patients' gender, age, place of residence, education, ethnicity, the type of clinic they visited and the presence of chronic diseases. Patient satisfaction was evaluated by using a short version of the Patient Satisfaction Questionnaire. We also used the Hospital Anxiety and Depression Scale. RESULTS: Poor evaluations of primary healthcare services were more characteristic of males, older patients, those living in district centres and villages, individuals with lower (secondary or lower) education levels, respondents of Russian ethnicity (compared to Lithuanian), patients with chronic diseases and higher anxiety and depression symptom scores. In the final regression analysis, better satisfaction with primary healthcare services was observed in respondents who were less depressed, of Polish ethnicity and who were living in a city rather than a village. CONCLUSIONS: Being more depressed or anxious, living in the district centre or countryside related to patients' worse satisfaction with primary healthcare services. The results of nationality of patients and their satisfaction are ambiguous. The is strong correlation between the symptoms of depression and anxiety.

Severe dyslipidemia and concomitant risk factors in the middle-aged Lithuanian adults: a cross-sectional cohort study.

BACKGROUND: Dyslipidemia is highly prevalent and is one of the major risk factors for cardiovascular disease in Lithuania. The purpose of this study was to determine the prevalence of severe dyslipidemia in Lithuanian middle aged primary prevention population and to investigate cardiovascular risk profile. METHODS: The group of 83,376 people were examined in the Lithuanian High Cardiovascular Risk primary prevention program (LitHiR), during 2009-2015 years. This study recruited middle aged men and women without overt cardiovascular disease. The prevalence of cardiovascular risk factors was compared between severe dyslipidemia group and control group. RESULTS: Severe dyslipidemia was present in 13.5% (11265) of the subjects; 66.6% (7508) were females. The subjects with severe dyslipidemia had significantly higher rates of arterial hypertension (63.5% vs. 44.2%, p < 0.001), diabetes mellitus (16% vs. 8.1%, p < 0,001), abdominal obesity (51% vs. 30.3%, p < 0.001), body mass index (BMI) > 30 (kg/m2) (38.8% vs. 24.1%, p < 0.001), metabolic syndrome (47.2% vs. 9.2%, p < 0.001), unbalanced diet (66.5% vs. 53.5%, p < 0.001), insufficient physical activity (56% vs. 44.2%, p < 0.001), family history of cardiovascular disease (29.7% vs. 22.7%, p < 0.001) in comparison with control group. Subjects without dyslipidemia had significantly higher rates of smoking (26.4% vs. 22.7%, p < 0.001). The prevalence of familial hypercholesterolemia was 0.1%, very high hypertriglyceridemia - 0.2% and familial mixed dyslipidemia - 0.1% of the subjects examined in the LitHiR programme. CONCLUSIONS: High prevalence of dyslipidemia remains a major problem in Lithuania. 9 out of 10 people have dyslipidemia, 1 out of 10 - severe dyslipidemia. Severe dyslipidemia is associated with higher frequency of other cardiovascular risk factors.

Arterial function parameters in patients with metabolic syndrome and severe hypertriglyceridemia.

BACKGROUND: Hypertriglyceridemia (hTG) is 1 of the dyslipidemia manifestations in patients with metabolic syndrome (MetS). However, for several decades, the role of hTG in cardiovascular risk was not well established. OBJECTIVE: The aim of this study was to assess the parameters of the vascular structure and function in patients with MetS and different degree of hTG. METHODS: Patients (aged 40-65 years) with MetS were divided into 3 groups by triglyceride (TG) levels according to National Cholesterol Education Program Adult Treatment Panel III Guidelines: severe hTG (TG ≥ 500 mg/dL), moderate hTG (TG 200-499 mg/dL), and a control (TG < 150 mg/dL) groups. Noninvasive assessment of vascular parameters (aortic augmentation index adjusted for heart rate 75 bpm [AixHR75], pulse wave velocity [PWV], flow-mediated dilatation, and common carotid artery intima-media thickness (IMT)) were performed. RESULTS: Among the 1938 patients analyzed, 1041 had hTG. Moderate hTG was observed in 90.40% (n = 941), whereas severe TG was observed in 9.6% (n = 100) of patients. Overall TG concentration was 231.17 ± 184.23 mg/dL; in severe hTG group, TG concentration was 795.36 ± 368.45 mg/dL, in moderate hTG group 285.20 ± 70.86 mg/dL, and 112.48 ± 24.80 mg/dL in control group. AIxHR75 and IMT were the lowest in the severe hTG group (P < .001 for both). Mean arterial pressure, carotid-radial PWV (9.25 ± 1.13 vs 9.24 ± 1.28 vs 8.91 ± 1.28; P < .001) as well as carotid-femoral PWV (8.63 ± 1.65 vs 8.75 ± 1.58 vs 8.51 ± 1.6; P = .006) were the higher in hTG groups compared with control. There were no significant differences between groups in flow-mediated dilatation (3.39 ± 2.01 vs 3.26 ± 2.43 vs 3.45 ± 2.61, P = .283). CONCLUSIONS: Patients with MetS and severe hTG have lower IMT and AIxHR75 and higher PWV and mean arterial pressure. Many factors could affect arterial parameters, and more research are needed to investigate arterial parameters and hTG connection.

Value of Duke treadmill score in predicting coronary artery lesion and the need for revascularisation.

BACKGROUND: Exercise electrocardiography is a long-standing method for the evaluation of coronary artery disease (CAD), and it remains the initial test for most patients who can exercise adequately with a baseline interpretable electrocardiogram. However, there is little information about the relationship between Duke treadmill test score (DTS) and severity of coronary artery lesion, as well as estimating the need for revascularisation. AIM: The aim of the study was to ascertain whether the DTS could be an efficient parameter in choosing coronary revascularisation in different DTS groups. METHODS: Two hundred and fifty-eight (n = 258) patients had positive exercise testing for CAD and underwent coronary angiography. The patients were divided into three groups according to the DTS: low-risk (with a score of ≥ +5), moderate-risk (with scores ranging from -10 to +4), and high-risk (with a score of ≤ -11). Coronary angiography was done by the Judkins technique. A coronary lesion was considered significant when stenosis of the coronary artery was ≥ 70% and stenosis of the trunk was ≥ 50%. The SYNTAX score was determined. RESULTS: The study group included 258 patients with mean age 62.66 ± 9.6 years, and most of them were men (72.8%). Patients with high- and intermediate-risk DTS had the same SYNTAX score (16.35 ± 7.3, 15.09 ± 10.08 and 11.80 ± 9.88, respectively; p = 0.064) compared to low-risk DTS. A negative correlation between DTS and significant coronary artery stenosis (r = -0.181; p = 0.005), SYNTAX score (r = -0.173; p = 0.007), and cardiac revascularisations (r = -0.213; p = 0.001) were found. In multiple linear regressions to predict coronary revascularisation the SYNTAX score (B = 0.018; p = 0.0001), DTS (B = -0.014, p = 0.008) and previous myocardial infarction (B = -0.143; p = 0.047) were significant predictors. CONCLUSIONS: The DTS alone is a useful tool in suspecting a significant coronary artery stenosis, but it is not accurate enough for revascularisation. Thus, by adding clinical information, its value may be maximised.
