Right-Ventricle Heart Failure in PAH vs. HFrEF with Secondary PH: Hemodynamic, Ergospirometric, and Organ Function Correlations.

PURPOSE: The goal of the study was to identify markers of organ function used in daily routines that could potentially aid in the overall evaluation of the cardiovascular system in patients with right-ventricle heart failure due to pulmonary arterial hypertension (PAH) and left-ventricle heart failure. We analyzed correlations between parameters from right heart catheterization (RHC), cardiopulmonary exercise test (CPET), and selected laboratory parameters of thyroid, liver, kidneys function and iron homeostasis. PATIENTS AND METHODS: A retrospective analysis included 107 patients (mean age 57.6±16.2; 34.6% women), comprising 57 patients with PAH (mean age 54.0±18.2; 49.1% women) and 50 patients with heart failure with reduced ejection fraction (HFrEF) <40% (mean age 61.6±12.7; 18% women). All patients underwent CPET. Each patient in the PAH group had RHC performed. Fifteen patients from the HFrEF group underwent RHC, which confirmed the suspicion of pulmonary hypertension (HFrEF-SPH). RESULTS: CPET and laboratory parameters' analysis showed strong correlations between ventilation/carbon dioxide production (VE/VCO2) slope and NT-proBNP in HFrEF without secondary PH and HFrEF-SPH groups. In the PAH group, VE/VCO2 slope correlated with liver and thyroid function but also with morphological parameters of red-cell system. Analysis of correlations between laboratory and hemodynamic parameters revealed significant correlations between pulmonary arterial pressure, pulmonary vascular resistance (PVR) and red-cell parameters, especially strong with fT4 in the PAH group. CONCLUSIONS: In HFrEF-SPH patients, laboratory parameters strongly correlated with pulmonary pressures and pulmonary capillary wedge pressure (PCWP).

The relationship between brain structure volumes, depressive symptoms and body composition in obese/overweight and normal-/underweight women.

Depressive symptoms are highly prevalent and heterogeneous in women. Different brain structures might be associated with depressive symptoms and body composition in women with obesity/overweight and normal-/underweight, although the data is limited. The analysis included 265 women from Bialystok PLUS population study, untreated with antidepressive or antipsychotic medications. The subjects underwent brain magnetic resonance imaging and body composition analysis. Beck Depression Inventory (BDI) score was inversely associated with nucleus accumbens volume (ß = -0.217, p = 0.008) in women with BMI ≥ 25 kg/m2, but with insula volume (ß = -0.147, p = 0.027) in women with BMI < 25 kg/m2 after adjustment for age and estimated intracranial volume (eTIV). In women with BMI ≥ 25 kg/m2, nucleus accumbens volume was inversely associated with the percentage of visceral fat and BDI score (ß = -0.236, p = 0.012, ß = -0.192, p = 0.017) after adjustment for age and eTIV. In women with BMI < 25 kg/m2, insula volume was positively associated with total fat-free mass and negatively with the BDI score (ß = 0.142, p = 0.030, ß = -0.137, p = 0.037) after adjustment for age and eTIV. Depressive symptoms might be associated with nucleus accumbens volume in overweight/obese women, while in normal-/ underweight women-with alterations in insula volume.

Cardiovascular risk and preclinical atherosclerosis are associated with white matter hyperintensities in apparently healthy adults: the population-based cross-sectional study BIALYSTOK PLUS.

INTRODUCTION: White matter hyperintensities, present in patients and asymptomatic individuals, have been previously shown to be associated with atherosclerosis risk factors like high blood pressure, hypercholesterolemia, smoking, and diabetes. OBJECTIVES: To assess the associations between white matter hyperintensities volume and cardiovascular risk factors in a general apparently healthy population. PATIENTS AND METHODS: The analysis includes 735 participants (age range 20 to 79) without neurological or severe cardiac diseases. The participants were subjected to detailed clinical examination, including medical history, biochemical analyses, carotid arteries ultrasound, and brain magnetic resonance imaging, followed by white matter hyperintensities segmentation using the Freesurfer tool. Participant were divided into three cardiovascular risk categories based on the 2021 European Society of Cardiology guidelines. RESULTS: The median volume of white matter hyperintensities was 95.2 mm3 (interquartile range 2.1 to 482.0 mm3). Multivariable analysis revealed positive, independent association between white matter hyperintensities volume and cardiovascular risk categories, glycated hemoglobin, presence of carotid plaques, and central systolic pressure. Analysis including people without hypertension or diabetes revealed mean intima-media thickness and high or very high cardiovascular risk class as independent predictors of white matter hyperintensities percentiles. CONCLUSION: The cardiovascular risk class, presence of carotid plaques, increased intima-media complex thickness and diabetes are the main risk factors for white matter hyperintensities in apparently healthy adults. People without hypertension or diabetes but with higher cardiovascular risk are also at risk of developing white matter hyperintensities, what emphasizes the value of assessment of the cardiovascular risk in the aspect of prediction of neurodegenerative changes.

Value of APACHE II, SOFA and CardShock scoring as predictive tools for cardiogenic shock: A single-centre pilot study.

AIMS: The aim of this study was to determine the value of the Acute Physiology and Chronic Health Evaluation II (APACHE II), Sequential Organ Failure Assessment (SOFA) and CardShock scoring systems in predicting the risk of in-hospital, 30 day and 3 year mortality in patients with cardiogenic shock (CS). METHODS: This was a single-centre observational study conducted between May 2016 and December 2017. Data from consecutive patients with CS admitted to the intensive cardiac care unit (ICCU) were included in the analysis. RESULTS: The study group comprised 63 patients with CS {median age 71.0 [interquartile range (IQR), 59-82]; 42 men}: 32 patients with ischaemic and 31 with non-ischaemic aetiology. The median APACHE II, SOFA and CardShock scores were 13 (IQR, 9.9-19.0) points, 8.0 (IQR, 6.0-10.0) points and 3.0 (IQR, 2.0-5.0) points, respectively. The in-hospital, 30 day and 3 year mortality rates were 39.7%, 41.3% and 77.8%, respectively. APACHE II and SOFA scores were significantly higher in the group of patients who died at 30 days (P = 0.043 and P = 0.045, respectively). The CardShock score was higher in patients with CS who died in hospital (P = 0.007) and within 30 days (P = 0.004). No score was statistically significant for 3 year mortality. Area under the curve (AUC) analysis showed that the CardShock score had the highest value in predicting in-hospital and 30 day mortality relative to APACHE II and SOFA, with a cut-off score of 5 points [AUC: 0.70; 95% confidence interval (CI): 0.59-0.81; P = 0.001] and 4 points (AUC: 0.71; 95% CI: 0.60-0.82; P < 0.001), respectively. The Bayesian Weibull model demonstrated the utility of all scales in estimating short-term risk in patients with CS, with the impact of APACHE II and SOFA on patient life expectancy decreasing to a non-significant level at approximately 32 days and CardShock at 33 days. The forest plots derived from the Bayesian logistic regression analysis show significant estimated coefficients with 94% highest density interval (HDI) for in-hospital and 30 day mortality. The use of invasive or non-invasive ventilation, a higher heart rate and a less negative fluid balance showed an unfavourable prognosis. Survival was associated with being in the pre-CS class, with a higher glomerular filtration rate and a higher platelet count. CONCLUSIONS: APACHE II and SOFA could be used for the risk stratification of patients with CS admitted to the ICCU. CardShock proved to be a more appropriate tool for assessing short-term prognosis in patients with CS of all aetiologies, suggesting that there is potential for its promotion for use in daily clinical practice.

Quality of Life in Patients with Coronary Artery Disease-Multicenter POLASPIRE II Study.

Background: The quality of life of patients with coronary heart disease is extremely important for their treatment. The aim of the study was to assess the quality of life of patients with coronary artery disease, considering education and compliance with medical recommendations regarding lifestyle changes, as well as the presence of selected cardiovascular risk factors. Methods: The study involved 763 patients from 11 Polish cardiology centers. The presented material is part of the multicenter POLASPIRE II study. Patients completed a standardized questionnaire EuroQol 5D-5Lm. A medical interview was conducted with each patient. All patients had their body weight and height measured and BMI determined. Results: The quality of life of patients was better in men, younger people, those with lower body weight and those who followed preventive recommendations and intensified their physical activity. Most of the examined patients complied with the medical recommendations regarding lifestyle changes after a cardiac incident, but they mainly concerned dietary modifications. There was still a large group of patients who did not comply with the recommendations, e.g., regarding increasing physical activity. Conclusions: The assessment of quality of life depended on many factors, such as gender, body weight and compliance with medical recommendations. The health education of patients in the presented study group was not sufficient. Therefore, there is a need for better education regarding the benefits of following medical recommendations in terms of leading a healthy lifestyle, which consequently improves its quality and duration.

Do the Gender and the Number of Comorbidities and the Use of Tertiary Prevention Play a Role in the Severity of Anxiety and Depression in Patients with Coronary Artery Disease? A POLASPIRE II Study.

Background/Objectives: The need to conduct research on anxiety and depression in patients with coronary artery disease in connection with factors such as gender or implemented tertiary prevention is very important for drawing practical conclusions and, consequently, implementing new recommendations and procedures. The aim of the study was to attempt to answer the question whether gender and the number of comorbidities, as well as the application of tertiary prevention principles, play a role in the severity of anxiety and depression in the studied group of patients with coronary artery disease. Material: The study involved 765 patients from 11 Polish cardiology centers. The presented material is part of the multicenter POLASPIRE II study. Methods: All patients completed The Hospital Anxiety and Depression Scale (HADS) questionnaire, and a medical interview was conducted with them. Conclusions: Although the intensity of anxiety and depression in the studied group of patients was low, gender differentiated them, which, however, did not influence undertaking tertiary prevention activities. In the study group of patients, the number of comorbidities and cardiac incidents/procedures after the event qualifying for the study, as well as preventive actions undertaken, were not associated with the severity of anxiety and depression. In the studied group of patients with coronary heart disease, there was still a large group of people who did not take preventive measures. Therefore, there is a need for systematic education regarding the benefits of implementing them to prevent the progression of the disease and premature death.

Cardiovascular risk and the COVID-19 pandemic: a population-based and case‒control studies.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic is associated with increases in morbidity and mortality worldwide. The mechanisms of how SARS-CoV-2 may cause cardiovascular (CV) complications are under investigation. The aim of the study was to assess the impact of the COVID-19 pandemic on CV risk. METHODS: These are single-centre Bialystok PLUS (Poland) population-based and case‒control studies. The survey was conducted between 2018 and 2022 on a sample of residents (n = 1507) of a large city in central Europe and patients 6-9 months post-COVID-19 infection (n = 126). The Systematic Coronary Risk Estimation 2 (SCORE2), the Systematic Coronary Risk Estimation 2-Older Persons (SCORE2-OP), the Cardiovascular Disease Framingham Heart Study and the LIFEtime-perspective model for individualizing CardioVascular Disease prevention strategies in apparently healthy people (LIFE-CVD) were used. Subsequently, the study populations were divided into CV risk classes according to the 2021 ESC Guidelines on cardiovascular disease prevention in clinical practice. RESULTS: The study population consisted of 4 groups: a general population examined before (I, n = 691) and during the COVID-19 pandemic (II, n = 816); a group of 126 patients post-COVID-19 infection (III); and a control group matched subjects chosen from the pre-COVID-19 pandemic (IV). Group II was characterized by lower blood pressure, low-density lipoprotein cholesterol (LDL-c) and high-density lipoprotein cholesterol (HDL-c) values than group I. Group III differed from the control group in terms of lower LDL-c level. There was no effect on CV risk in the general population, but in the population post-COVID-19 infection, CV risk was lower using FS-lipids, FS-BMI and LIFE-CVD 10-year risk scores compared to the prepandemic population. In all subgroups analysed, no statistically significant difference was found in the frequency of CV risk classes. CONCLUSIONS: The COVID-19 pandemic did not increase the CV risk calculated for primary prevention. Instead, it prompted people to pay attention to their health status, as evidenced by better control of some CV risk factors. As the COVID-19 pandemic has drawn people's attention to health, it is worth exploiting this opportunity to improve public health knowledge through the design of wide-ranging information campaigns.

Cardiac PET/MRI: Recent Developments and Future Aspects.

Positron emission tomography/magnetic resonance (PET/MRI) hybrid imaging is now available for over a decade and although the quantity of installed systems is rather low, the number of emerging applications for cardiovascular diseases is still growing. PET/MRI provides integrated images of high quality anatomical and functional assessment obtained by MRI with the possibilities of PET for quantification of molecular parameters such as metabolism, inflammation, and perfusion. In recent years, sequential co-registration of myocardial tissue characterization with its molecular data had become an increasingly helpful tool in clinical practice and an integrated device simplifies this task. This review summarizes recent developments and future possibilities in the use of the PET/MRI in the diagnosis and treatment of cardiovascular disorders.

Assessment of smell disturbances 6 months after COVID-19 in Polish population.

Considering the frequency and severity of olfactory disorders associated with SARS-CoV-2 infection, attention to the olfactory loss has expanded. The aim of our study was to assess of smell disturbances 6 months after COVID-19. The study population consisted of 2 groups: 196 Post-COVID-19 patients who were hospitalized because of COVID-19, control sample-130 patients without reported smell disorders from general population-Bialystok PLUS study. People from both groups were asked to participate in the Sniffin Sticks Test (half year after the disease). Sniffin Sticks Test consisted of 12 standardized smell samples. The participant's test score was counted based on correct scent recognition. Middle/older age was related with lower likelihood of olfaction recovery. The biggest differences in recognition of particular fragrances were observed for: orange and lemon, lemon and coffee (p.adj < 0.001). Patients had the greatest problem in assessing smell of lemon. The comparison of scores between Delta, Omicron, Wild Type, Wild Type Alpha waves showed statistically significant difference between Delta and Wild Type waves (p = 0.006). Duration of the disease (r = 0.218), age (r = -0.253), IL-6 (r = -0.281) showed significant negative correlations with the score. Statistically significant variables in the case of smell disorders were Omicron wave (CI = 0.045-0.902; P = 0.046) and Wild Type wave (CI = 0.135-0.716; P = 0.007) compared to Delta wave reference. Moreover, patients with PLT count below 150 000/µl had greater olfactory disorders than those with PLT count over 150 000/µl. There are: smell differences between post-COVID-19 patients and healthy population; statistically significant difference between Delta and Wild Type waves in Post-COVID-19 group in score of the Sniffin Sticks Test. Smell disturbances depend on the age, cognitive impairments, clinical characteristics of the COVID-19 disease and sex of the patient.

Detraining among Athletes-Is Withdrawal of Adaptive Cardiovascular Changes a Hint for the Differential Diagnosis of Physically Active People?

An athlete's training aims to achieve the highest possible sports results by improving physical dispositions which lead to cardiac adaptive changes. The annual training cycle is divided into periods. The preparatory period begins with gradually increasing training intensity and volume until the competitive period occurs, when the athlete's maximum performance is expected. Finally, the athlete enters a phase of loss of fitness, which is called detraining. Detraining is a time of resting both physically and mentally from the training regime and usually lasts about 4 weeks for endurance athletes. We collected data from much research on athletes' detraining. According to these data, the earliest change after detraining seems to be a decrease in left ventricular wall thickness and left ventricular mass, followed by decreased performance parameters, diastolic diameter of the left ventricle and size of the left atrium. A reversal of adaptive changes affects the left heart chamber first, then the right atrium and, finally, the right ventricle. Training reduction is often proposed as a method of differentiating an athlete's heart from cardiomyopathies. The aim of this study is to consider the diagnostic value of detraining in differentiating athletes' hearts from cardiomyopathies. We suggest that detraining cannot be conclusive in differentiating the disease from adaptive changes. Although a withdrawal of the characteristic morphological, functional and electrocardiographic changes occurs in healthy athletes during detraining, it can also concern individuals with cardiomyopathies due to the lower expression of abnormal features after decreased training loads. Therefore, a quick diagnosis and individual assessments using imaging and genetic tests are essential to recommend a proper type of activity.

Alteration in kynurenine pathway metabolites in young women with autoimmune thyroiditis.

The kynurenine pathway (KP) of tryptophan degradation includes several compounds that reveal immunomodulatory properties. The present study aimed to investigate the alteration in KP metabolites in young women with autoimmune thyroiditis (AIT) and their associations with thyroid function. The thyroid function tests, antithyroid antibodies measurement and ultrasonography of the thyroid gland have been performed in 57 young women with AIT and 38 age-matched healthy controls. The serum levels of tryptophan, kynurenine (KYN) and its metabolites were determined, and the activity of KP enzymes was calculated indirectly as product-to-substrate ratios. KP was activated and dysregulated in AIT, along with significantly elevated levels of KYN and anthranilic acid (AA), at the expense of the reduction of kynurenic acid (KYNA), which was reflected by the increase in the AA/KYNA ratio (p < 0.001). In univariate and multiple regression analyses, peripheral deiodinase (SPINA-GD) activity in AIT was positively associated with KYNA, AA, and quinolinic acid (QA). The merger of AA, AA/KYNA ratio, QA and SPINA-GD exhibited the highest sensitivity and specificity to predict AIT (p < 0.001) in receiver operating characteristic (ROC) analysis. In conclusion, the serum KYN metabolite profile is dysregulated in young women with AIT and could serve as a new predictor of AIT risk.

Medical Misinformation in Polish on the World Wide Web During the COVID-19 Pandemic Period: Infodemiology Study.

BACKGROUND: Although researchers extensively study the rapid generation and spread of misinformation about the novel coronavirus during the pandemic, numerous other health-related topics are contaminating the internet with misinformation that have not received as much attention. OBJECTIVE: This study aims to gauge the reach of the most popular medical content on the World Wide Web, extending beyond the confines of the pandemic. We conducted evaluations of subject matter and credibility for the years 2021 and 2022, following the principles of evidence-based medicine with assessments performed by experienced clinicians. METHODS: We used 274 keywords to conduct web page searches through the BuzzSumo Enterprise Application. These keywords were chosen based on medical topics derived from surveys administered to medical practitioners. The search parameters were confined to 2 distinct date ranges: (1) January 1, 2021, to December 31, 2021; (2) January 1, 2022, to December 31, 2022. Our searches were specifically limited to web pages in the Polish language and filtered by the specified date ranges. The analysis encompassed 161 web pages retrieved in 2021 and 105 retrieved in 2022. Each web page underwent scrutiny by a seasoned doctor to assess its credibility, aligning with evidence-based medicine standards. Furthermore, we gathered data on social media engagements associated with the web pages, considering platforms such as Facebook, Pinterest, Reddit, and Twitter. RESULTS: In 2022, the prevalence of unreliable information related to COVID-19 saw a noteworthy decline compared to 2021. Specifically, the percentage of noncredible web pages discussing COVID-19 and general vaccinations decreased from 57% (43/76) to 24% (6/25) and 42% (10/25) to 30% (3/10), respectively. However, during the same period, there was a considerable uptick in the dissemination of untrustworthy content on social media pertaining to other medical topics. The percentage of noncredible web pages covering cholesterol, statins, and cardiology rose from 11% (3/28) to 26% (9/35) and from 18% (5/28) to 26% (6/23), respectively. CONCLUSIONS: Efforts undertaken during the COVID-19 pandemic to curb the dissemination of misinformation seem to have yielded positive results. Nevertheless, our analysis suggests that these interventions need to be consistently implemented across both established and emerging medical subjects. It appears that as interest in the pandemic waned, other topics gained prominence, essentially "filling the vacuum" and necessitating ongoing measures to address misinformation across a broader spectrum of health-related subjects.

Inflammation and Neurodegeneration in Glaucoma: Isolated Eye Disease or a Part of a Systemic Disorder? - Serum Proteomic Analysis.

Introduction: Glaucoma is the most common optic neuropathy and the leading cause of irreversible blindness worldwide, which affects 3.54% of the population aged 40-80 years. Despite numerous published studies, some aspects of glaucoma pathogenesis, serum biomarkers, and their potential link with other diseases remain unclear. Recent articles have proposed that autoimmune, oxidative stress and inflammation may be involved in the pathogenesis of glaucoma. Methods: We investigated the serum expression of 92 inflammatory and neurotrophic factors in glaucoma patients. The study group consisted of 26 glaucoma patients and 192 healthy subjects based on digital fundography. Results: Patients with glaucoma had significantly lower serum expression of IL-2Rß, TWEAK, CX3CL1, CD6, CD5, LAP TGF-beta1, LIF-R, TRAIL, NT-3, and CCL23 and significantly higher expression of IL-22Rα1. Conclusion: Our results indicate that patients with glaucoma tend to have lower levels of neuroprotective proteins and higher levels of neuroinflammatory proteins, similar to those observed in psychiatric, neurodegenerative and autoimmune diseases, indicating a potential link between these conditions and glaucoma pathogenesis.

First-year follow-up costs of myocardial infarction management in Poland from the payer's perspective.

BACKGROUND: Myocardial infarction (MI) remains a major burden for healthcare systems. Therefore, we intended to analyze the determinants of cost management of patients hospitalized for MI in Poland. METHODS: Data on patients hospitalized and discharged with the diagnosis of acute MI were derived from the public payer claims database. Adult patients, reported between October 1, 2017 and December 31, 2019, were included. Costs of hospitalization for acute MI and cumulative one-year follow-up were analyzed. RESULTS: The median (IQR) of the total direct cost was €3804.7 (2674.1-5712.7) per patient and 29% (€1113.6 [380.5-2490.4]) of these were costs related to the use of post-hospitalization healthcare resources. The median cost of cardiovascular disease management was €3624.7 (2582.1-5258.5), and 26% of this sum were follow-up costs. The analysis of the total cost for individual years showed a slight increase in median costs in subsequent years: €3450.7 (2407.8-5205.2) in 2017, €3753.8 (2642.6-5681.9) in 2018, and €3944.9 (2794.8-5844.4) in 2019. Male sex, heart failure, atrial fibrillation, diabetes, kidney disease, chronic obstructive pulmonary disease, and history of stroke in addition to hospitalization in a department other than cardiology or internal disease were independently related to the cost of MI patient management. CONCLUSIONS: The high cost of management of MI patients was independently related to sex, heart failure, atrial fibrillation, diabetes, kidney disease, chronic obstructive pulmonary disease, and history of stroke as well as hospitalization in other than cardiology or internal disease department.

Targeted proteomics in a population-based study identifies serum PECAM-1 and TRIM21 as inflammation markers for periodontitis.

OBJECTIVES: Periodontitis (PD) can cause systematic inflammation and is associated with various metabolic processes in the body. However, robust serum markers for these relationships are still lacking. This study aims to identify novel circulating inflammation-related proteins associated with PD using targeted proteomics. MATERIALS AND METHODS: We used population-based, cross-sectional data from 619 participants of the Polish Longitudinal University Study (Bialystok PLUS). Mean pocket probing depth (mPPD) and proportion of bleeding on probing (pBOP) served as exposure variables. Fifty-two inflammation-related proteins were measured using the Olink Target 96 Cardiovascular III and the Olink Target 96 Immune Response panels. Associations between periodontal measures and proteins were tested using covariate-adjusted linear regression models. RESULTS: At a false discovery rate of < 0.05, we identified associations of mPPD and pBOP with platelet-endothelial cell adhesion molecule-1 (PECAM-1) and tripartite motif-containing protein 21 (TRIM21). CONCLUSION: This study revealed novel associations between PD and serum levels of PECAM-1 and TRIM21. Our results suggest that these proteins might be affected by molecular processes that take place in the inflamed periodontium. CLINICAL RELEVANCE: Novel associations of PECAM-1 and TRIM21 with PD indicate promising serum markers for understanding the disease's pathophysiological processes and call for further biomedical investigations.

The prevalence of age-related macular degeneration and osteoporosis in the older Polish population: Is there a link?

BACKGROUND: Age-related macular degeneration is the primary cause of irreversible blindness in developed countries, whereas the global prevalence of osteoporosis-a major public health problem-is 19.7%. Both diseases may coincide in populations aged >50 years, leading to serious health deterioration and decreased quality of life. OBJECTIVES: This study aimed to analyze the relationship between age-related macular degeneration and osteopenia, defined as decreased bone mineral density, in the Polish population. METHODS: Participants were derived from the population-based Bialystok PLUS Study. Randomized individuals were stratified into two groups, those with age-related macular degeneration (AMD-1 group) or without age-related macular degeneration (AMD-0 group). Using a cutoff value of -1.0 to identify low bone mass, participants with femoral bone mineral density T-scores above -1.0 were assigned to the normal reference, and those with T-scores below -1.0 were assigned to the osteopenia category. Among 436 Caucasian participants aged 50-80 years (252 women, 184 men), the prevalence of age-related macular degeneration was 9.9% in women and 12.0% in men. Decreased bone mineral density based on T-scores was observed in 36.9% of women and in 18.9% of men. Significant differences in femoral bone mineral density between the AMD-0 and AMD-1 groups were detected only in men (mean difference [95% confidence interval] = 0.11 (0.02; 0.13); p = 0.012 for femoral bone mineral density, and 0.73 [0.015; 0.94]; p = 0.011 for the femoral T-score). No associations were observed between bone mineral density and age-related macular degeneration in women. CONCLUSION: Decreased femoral bone mineral density may be associated with a higher risk of age-related macular degeneration in men, but a causal link remains unclear.

Long-term effects of COVID-19 on the endocrine system - a pilot case-control study.

Background: Coronavirus disease 2019 (COVID-19) has permanently changed the world. Despite having been a pandemic for nearly 3 years, the mid- and long-term complications of this disease, including endocrine disorders, remain unclear. Our study aimed to evaluate the lasting effects of COVID-19 on the endocrine system 6 months after initial infection. Methods: We compared patients who underwent COVID-19 to age- and sex-matched subjects from a population-based study conducted before the pandemic. We evaluated differences in multiple parameters related to metabolism and the endocrine system including fasting glucose, insulin, lipids, body composition, thyroid stimulating hormone (TSH), free thyroxine (fT4), free triiodothyronine (fT3), anti-thyroglobulin (aTG) and anti-thyroid peroxidase (aTPO) antibodies, prolactin, cortisol, testosterone, and estradiol. Results: We found significantly lower levels of fT3 and fT4, accompanied by higher levels of TSH and aTPO antibodies, in COVID-19 survivors. Moreover, we found that patients who underwent SARS-CoV2 infection had higher levels of prolactin and lower levels of testosterone than controls. Interestingly, differences in testosterone levels were observed only in male subjects. We did not detect significant differences in body composition or metabolic and glycemic parameters between cases and controls, except for significantly higher values of the HOMA2-B index in COVID-19 survivors. Conclusion: Our study indicates that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection might have long-term consequences on the endocrine system, including the suppressed function of the thyroid gland, prolactin, and male sex hormone secretion. Moreover, we showed that in a 6-month follow-up, COVID-19 had no consequences on glycemic parameters, lipid profiles, liver function, body composition, cortisol levels, and estradiol levels.

The association between plasma N-terminal pro-brain natriuretic peptide concentration and metabolic disturbances in women with depressive symptoms.

BACKGROUND: The relationship between brain natriuretic peptides and depression was studied in patients with cardiovascular diseases (CVD), but the data in people without CVD are limited. Metabolic disturbances can be associated with natriuretic peptides' levels. The study aimed to assess serum N-terminal pro-brain natriuretic peptide (NT-proBNP) level in women with depressive symptoms and its relationship with metabolic disturbances. METHODS: The analysis included 347 women (20-60 years old) from Bialystok PLUS cohort study: 98 with depressive symptoms and 249 controls. Clinical examination, oral glucose tolerance test (OGTT) and assessment of lipid, sex hormone binding globulin (SHBG) and NT-proBNP concentrations in the blood were performed. The participants completed Beck Depression Inventory questionnaire. RESULTS: Metabolic syndrome was more frequent in the group of women with depressive symptoms compared to women without depressive symptoms. Women with depressive symptoms had lower NT-proBNP level than the control group - 45.88 (27.80-67.04) vs 56.49 (32.42-94.25) pg/mL, p = 0.027. Multiple linear regression analysis of all women showed that NT-proBNP level was reversely associated with the presence of depressive symptoms, waist circumference and heart rate and positively connected with age. In the group of women with depressive symptoms, we observed negative correlations between NT-proBNP level and insulin concentration at 60 min of OGTT, diastolic blood pressure and a positive correlation with SHBG. CONCLUSIONS: NT-proBNP level is decreased in women with depressive symptoms, which might be connected with metabolic disturbances in this group.

The FCGR2A Is Associated with the Presence of Atherosclerotic Plaques in the Carotid Arteries-A Case-Control Study.

BACKGROUND: Atherosclerotic plaques in carotid arteries (APCA) are a prevalent condition with severe potential complications. Studies continuously search for innovative biomarkers for APCA, including those participating in cellular metabolic processes, cell adhesion, immune response, and complement activation. This study aimed to assess the relationship between APCA presence and a broad range of cardiometabolic biomarkers in the general population. METHODS: The study group consisted of consecutive participants of the population study Bialystok PLUS. The proximity extension assay (PEA) technique from the Olink Laboratory (Uppsala, Sweden) was used to measure the levels of 92 cardiometabolic biomarkers. RESULTS: The study comprised 693 participants (mean age 48.78 ± 15.27 years, 43.4% males, N = 301). APCA was identified in 46.2% of the participants (N = 320). Of the 92 biomarkers that were investigated, 54 were found to be significantly linked to the diagnosis of APCA. After adjusting for the traditional risk factors for atherosclerosis in multivariate analysis, the only biomarker that remained significantly associated with APCA was FCGR2A. CONCLUSION: In the general population, the prevalence of APCA is very high. A range of biomarkers are linked with APCA. Nonetheless, the majority of these associations are explained by traditional risk factors for atherosclerosis. The only biomarker that was independently associated with APCA was the FCGR2A.
