Estimation of recurrent atherosclerotic cardiovascular event risk in patients with established cardiovascular disease: the updated SMART2 algorithm. Eur Heart J 2022; 43:1715-1727. [PMID: 35165703 PMCID: PMC9312860 DOI: 10.1093/eurheartj/ehac056] [Citation(s) in RCA: 26] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/24/2021] [Revised: 12/30/2021] [Accepted: 01/18/2022] [Indexed: 11/19/2022] Open
Abstract
AIMS The 10-year risk of recurrent atherosclerotic cardiovascular disease (ASCVD) events in patients with established ASCVD can be estimated with the Secondary Manifestations of ARTerial disease (SMART) risk score, and may help refine clinical management. To broaden generalizability across regions, we updated the existing tool (SMART2 risk score) and recalibrated it with regional incidence rates and assessed its performance in external populations. METHODS AND RESULTS Individuals with coronary artery disease, cerebrovascular disease, peripheral artery disease, or abdominal aortic aneurysms were included from the Utrecht Cardiovascular Cohort-SMART cohort [n = 8355; 1706 ASCVD events during a median follow-up of 8.2 years (interquartile range 4.2-12.5)] to derive a 10-year risk prediction model for recurrent ASCVD events (non-fatal myocardial infarction, non-fatal stroke, or cardiovascular mortality) using a Fine and Gray competing risk-adjusted model. The model was recalibrated to four regions across Europe, and to Asia (excluding Japan), Japan, Australia, North America, and Latin America using contemporary cohort data from each target region. External validation used data from seven cohorts [Clinical Practice Research Datalink, SWEDEHEART, the international REduction of Atherothrombosis for Continued Health (REACH) Registry, Estonian Biobank, Spanish Biomarkers in Acute Coronary Syndrome and Biomarkers in Acute Myocardial Infarction (BACS/BAMI), the Norwegian COgnitive Impairment After STroke, and Bialystok PLUS/Polaspire] and included 369 044 individuals with established ASCVD of whom 62 807 experienced an ASCVD event. C-statistics ranged from 0.605 [95% confidence interval (CI) 0.547-0.664] in BACS/BAMI to 0.772 (95% CI 0.659-0.886) in REACH Europe high-risk region. The clinical utility of the model was demonstrated across a range of clinically relevant treatment thresholds for intensified treatment options. CONCLUSION The SMART2 risk score provides an updated, validated tool for the prediction of recurrent ASCVD events in patients with established ASCVD across European and non-European populations. The use of this tool could allow for a more personalized approach to secondary prevention based upon quantitative rather than qualitative estimates of residual risk.

Abstract
INTRODUCTION The adherence to health-promoting behaviors intended to mitigate modifiable risk factors plays an important role in the secondary CV prevention. OBJECTIVES To evaluate gender differences in the prevalence and control of risk factors in patients with coronary heart disease (CHD). PATIENTS AND METHODS The study included 1236 patients with acute coronary syndrome or coronary revascularization within the last 6-24 months. Definitions of risk factors and treatment goals are based on the 2016 ESC guidelines on cardiovascular prevention. RESULTS The prevalence of modifiable risk factors in both sexes was high and their control inadequate. Women were older (P <0.001) and had higher accumulation of multiple CV risk factors than men (P = 0.036). They had more frequently central obesity (P <0.001) and reduced GFR values (P <0.001). Women more often experienced anxiety (P <0.001), reported lower levels of education (P <0.001) and lower income (P = 0.001), and in the youngest age group were more likely to be exposed to the secondhand smoking (P = 0.01). A large fraction of study patients, men and women alike, did not meet the recommended therapeutic goals. For both sexes, participation in cardiac rehabilitation programs was associated with more frequent attainment of the recommended level of physical activity (P = 0.046) and smoking cessation (P = 0.010). CONCLUSIONS The prevalence of CV risk factors in CHD patients is high, especially in women. Therapeutic goals are met infrequently in both genders. This situation calls for widening the access to educational programs and higher attention to their proper implementation.

Serum Chemerin Concentration Is Associated with Proinflammatory Status in Chronic Coronary Syndrome. Biomolecules 2021; 11:biom11081149. [PMID: 34439815 PMCID: PMC8392272 DOI: 10.3390/biom11081149] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2021] [Revised: 07/26/2021] [Accepted: 07/29/2021] [Indexed: 12/12/2022] Open
Abstract
Background: Chemerin is an adipokine and a chemoattractant for leukocytes. Increased chemerin levels were observed in patients with coronary artery disease (CAD). We investigated associations between chemerin and biochemical measurements or body composition in CAD patients. Methods: In the study, we included patients with stable CAD who had undergone percutaneous coronary intervention (PCI) in the past. All patients had routine blood tests, and their insulin and chemerin serum levels were routinely measured. Body composition was assessed with the DEXA method. Results: The study group comprised 163 patients (mean age 59.8 ± years, 26% of females, n = 43). There was no significant difference in serum chemerin concentrations between patients with diabetes and the remaining ones: 306.8 ± 121 vs. 274.15 ± 109 pg/mL, p = 0.1. Chemerin correlated positively with the white blood cell (WBC) count, the neutrophil to lymphocyte ratio, hsCRP, all fractions of cholesterol, triglycerides, platelet count, fasting insulin, and c-peptide. Chemerin levels were also correlated with total fat mass but only in a subgroup with normal glucose metabolism. Conclusion: In patients with CAD, serum chemerin levels are correlated with inflammation markers, insulin resistance, and an unfavorable lipid profile. Correlation with fat mass is dependent on glucose metabolism status. Depending on the presence of diabetes/prediabetes, the mechanisms regulating chemerin secretion may be different.

The relationship between interleukin-13 and angiogenin in patients with bladder cancer. JOURNAL OF PHYSIOLOGY AND PHARMACOLOGY : AN OFFICIAL JOURNAL OF THE POLISH PHYSIOLOGICAL SOCIETY 2021; 72. [PMID: 35072652 DOI: 10.26402/jpp.2021.4.13] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Received: 07/19/2021] [Accepted: 10/30/2021] [Indexed: 06/14/2023]
Abstract
Participation of anti-inflammatory interleukin-13 (IL-13) in the process of carcinogenesis was well studied. Angiogenesis plays a key role in the process of tumour growth and metastasis. Higher expression of angiogenin (ANG) have been proven in many types of cancers. The aim of the study was to more fully understand the significance of plasma IL-13 as an immunomodulator and ANG as a stimulator of the angiogenesis process in patients with bladder cancer (BC) and to investigate the relationship between parameters. These parameters were examined in the group of BC patients and in subgroups of BC depending on clinical stage: non-muscle invasive bladder cancer (NMIBC), muscle invasive bladder cancer (MIBC), histopathologic malignancy low grade (LG), high grade (HG) and in primary and recurrent BC. The level of IL-13 and ANG in the plasma of BC patients and controls were measured by enzyme-linked immunosorbent assay. All calculations were done using the STATISTICA 13.3 (TIBCO software Inc.). Plasma levels of IL-13 and ANG were significantly higher in BC patients and in all patient subgroups examined than in the controls (p < 0.001). A negative significant correlation was found between ANG and IL-13 levels in BC-patients. Based on the receiver operating characteristic curves (ROC), IL-13 had good diagnostic value in BC. The presented results may suggest a relationship between angiogenesis and inflammation in the pathogenesis of bladder cancer and the development of this disease. With the increase of IL-13 level in BC-patients plasma, the ANG level decreased.

Effectiveness and safety of a simple home-based rehabilitation program in pulmonary arterial hypertension: an interventional pilot study. BMC Sports Sci Med Rehabil 2021; 13:79. [PMID: 34321095 PMCID: PMC8316895 DOI: 10.1186/s13102-021-00315-y] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2020] [Accepted: 07/16/2021] [Indexed: 01/29/2023]
Abstract
BACKGROUND Rehabilitation plays an important role in the management of patients with pulmonary arterial hypertension (PAH) and current guidelines recommend implementation of a monitored individualized exercise training program as adjuvant therapy for stable PAH patients on optimal medical treatment. An optimal rehabilitation model for this group of patients has not yet been established. This randomized prospective study assessed the effectiveness and safety of a 6-month home-based caregiver-supervised rehabilitation program among patients with pulmonary arterial hypertension. METHODS A total of 39 patients with PAH were divided into two groups: intervention group (16 patients), subjected to a 6-month home-based physical training and respiratory rehabilitation program adapted to the clinical status of participants, and control group (23 patients) who did not perform physical training. The 6-min walk test (6MWT), measurement of respiratory muscle strength, quality of life assessment (SF-36, Fatigue Severity Scale - FSS) were performed before study commencement, and after 6 and 12 months. Adherence to exercise protocol and occurrence of adverse events were also assessed. RESULTS Physical training significantly improved 6MWT distance (by 71.38 ± 83.4 m after 6 months (p = 0.004), which remained increased after 12 months (p = 0.043), and respiratory muscle strength after 6 and 12 months (p < 0.01). Significant improvement in quality of life was observed after the training period with the use of the SF-36 questionnaire (Physical Functioning, p < 0.001; Role Physical, p = 0.015; Vitality, p = 0.022; Role Emotional, p = 0.029; Physical Component Summary, p = 0.005), but it did not persist after study completion. Adherence to exercise protocol was on average 91.88 ± 14.1%. No serious adverse events were noted. CONCLUSION According to study results, the home-based rehabilitation program dedicated to PAH patients is safe and effective. It improves functional parameters and quality of life. Strength of respiratory muscles and 6MWD remain increased 6 months after training cessation. TRIAL REGISTRATION ClinicalTrials.gov , NCT03780803 . Registered 12 December 2018.

Abstract
Cardiovascular diseases (CVDs) are the leading cause of death in Poland. Starting from 1992, a gradual decrease in mortality due to CVDs has been observed, which is less noticeable in women. Following this notion, we assessed sex differences in the implementation of ESC recommendations regarding lipid control and the use of statins as part of secondary CVDs prevention in 1236 patients with acute coronary syndrome or elective coronary revascularization within the last 6-24 months. During hospitalization women had more frequently abnormal TC levels than men (p = 0.035), with overall higher TC levels (p = 0.009) and lower HDL-C levels (p = 0.035). In the oldest group, they also had more frequently elevated LDL-C levels (p = 0.033). Similar relationships were found during the follow-up visit. In addition, women less often achieved the secondary lipid therapeutic goal for non-HDL-C (p = 0.009). At discharge from hospital women were less frequently prescribed statins (p = 0.001), which included high-intensity statins (p = 0.002). At the follow-up visit the use of high-intensity statins was still less frequent in women (p = 0.02). We conclude that women generally have less optimal lipid profiles than men and are less likely to receive high-intensity statins. There is a need for more organized care focused on the management of risk factors.

Abstract
BACKGROUND Smoking cessation in patients with coronary artery disease (CAD) is related to decreased risk of cardiovascular events. AIMS To evaluate factors related to persistent smoking in patients with established coronary artery disease. METHODS Patients aged 80 years or younger and hospitalized for acute coronary syndrome or a myocardial revascularization procedure were interviewed 6 to 18 months after the recruiting event. Medical history, smoking behavior, and exposure to environmental smoke were assessed during the interview. Self--reported smoking status was validated by carbon monoxide in exhaled air measurement. Persistent smoking was defined as smoking at the time of interview among those who smoked during the month prior to the recruiting event. RESULTS We analyzed the data of 1034 patients, including 764 (73.9%) who reported smoking at any time in the past and 296 (28.6%) who smoked within 1 month before the recruiting hospitalization. At the time of the interview, the overall smoking rate was 17.2%, whereas 54.7% of patients were persistent smokers. Secondhand smoke exposure and duration of smoking were associated with lower likelihood whereas older age, high socioeconomic status, cardiac rehabilitation following a cardiovascular event, and consultation with a cardiologist were associated with higher likelihood of smoking cessation. CONCLUSIONS Over half of all smokers hospitalized for CAD are still smoking 6 to 18 months after discharge. Older age, secondhand smoking, low socioeconomic status, lack of consultation with a cardiologist, and cardiac rehabilitation following hospitalization were related to persistent smoking. Our findings may help develop strategies aimed at assisting smoking cessation in patients with CAD.

Abstract
Abstract
Left ventricular hypertrophy (LVH) is an important risk factor of various cardiovascular (CV) diseases and sudden death. Electrocardiography (ECG) is commonly used to detect LVH, but it has poor sensitivity, especially in high cardiovascular risk patients. Although echocardiography (ECHO) is a better, it is less available, and more expensive. Aim: To improve ECG scores to diagnose LVH in a general population.
Methods
The study was conducted in 2017–2019 in a representative sample of area residents. 717 volunteers randomly chosen from the local population were examined. Due to incomplete data, QRS complex duration ≥120ms, fascicular blocks, bundle branch blocks, paced rhythm, 216 people were excluded. Physical examination, ECG, ECHO and laboratory assessment were performed. In ECG LVH defined as >28mm for men, >20mm for women using Cornell index; >17mm for both sexes using Lewis index. In ECHO LV mass was calculated using the Devereux Formula and indexed by body surface area (left ventricular mass index – LVMI). The LVH was defined as LVMI ≥115 g/m2 for man and ≥95 g/m2 for women. Cardiovascular risk was calculated based on the ESC SCORE and additional risk categories published in the latest ESC guidelines. We analyzed 4 models to predict the probability of LVH at ECHO: Model 1: Cornell index; Model 2: Lewis index; Model 3: Cornel index + clinical parameters (age, sex, BMI, office BPs, QRS time, hs-TnT, and HbA1c); Model 4: Lewis index + clinical parameters (age, sex, BMI, office BPs, QRS time, hs-TnT, and HbA1c). Associations between LVH and clinical and biochemical variables were earlier analyzed using multiple linear regression models, these parameters were independently associated with LVH.
Results
A total of 501 patients were included. The average age of patients was 49.0±15.35 years, and 203 probants (40.5%) were male. We developed a novel score to assess the probability of LVH at ECHO in general population based on nine items (age, sex, body mass index, office BPs, Cornell index or Lewis index, QRS time, hs-TnT, and HbA1c). Additional clinical parameters improved sensitivity of Cornell index up to 86.0% (AUC:0.8011; 95% CI:0.748–0.854) from 64.9% (AUC:0.6450; 95% CI:0.573–0.716) in general population, to 92.9% (AUC:0.8423; 95% CI:0.760–0.924) from 64.3% (AUC:0.6481; 95% CI:0.518–0.779) in low CV risk patients, to 69.2% (AUC:0.6767; 95% CI:0.544–0.809) from 38.5% (AUC:0.5284; 95% CI:0.352–0.705) in moderate CV risk, and to 73.3% (AUC:0.7151; 95% CI: 0.609–0.821) of Lewis index from 50.0% (AUC: 0.5630; 95% CI:0.448–0.678) in high and very-high CV risk class.
Conclusions
Addition of clinical parameters to ECG indices in the diagnosis of LVH markedly improves their diagnostic efficacy both in general population and in higher risk groups. The new score may be useful in guiding the appropriateness of ECHO study in general population, and especially in moderate and high CV risk patients, who are not always aware of the increased CV risk.

Abstract
Abstract
Background
Chemerin – a recently described hormone is secreted by adipose tissue. It exerts proinflammatory action, leads to insulin resistance, but also has potentially favorable effects: it increases eNOS activity and is pro-angiogenic. Increased serum concentrations of chemerin was observed in patients with coronary artery disease (CAD). The role of chemerin in pathogenesis of CAD is not well understood.
Purpose
The aim of this pilot study was to assess the role of chemerin in pathogenesis of atherosclerosis, its impact on condition of large arteries and prognosis in CAD.
Methods
We included in the study patients with stable CAD who underwent percutaneous coronary intervention (PCI) in the past. Chemerin levels were measured with ELISA method. All patients had routine blood tests and insulin levels measured. Patients without history of diabetes also had OGTT. Status of large arteries was evaluated with carotid ultrasound, pulse-wave velocity (PWV) and ankle-brachial index (ABI). Body composition was assessed wit DEXA method. Anatomical severity of CAD was evaluated with SYNTAX score. One-year composite endpoint included death, myocardial infarction, revascularization, stroke and hospitalization for cardiovascular reasons.
Results
The study group comprised 163 patients (mean age 59.8± years, 26% of females, n=43). Mean chemerin level was 284.8 ng/ml. There was no significant difference in chemerin concentrations between patients with diabetes and remaining ones (with prediabetes and with normal glucose levels) 306.8±121 vs 274.15±109 pg/ml, p=0.1. In Spearman test chemerin level correlated with total fat mass (R=0.15, p=0.047), trunk fat mass (R=0.16, p=0.039), android fat mass (R=0.16, p=0.036), and BMI (R=0.18, p=0.028). Chemerin also correlated with white blood cells (WBC) count (R=0.34, p<0.0001), hsCRP (R=0.16, p=0.03), total cholesterol (R=0.17, p=0.028), LDL cholesterol (R=0.19, p=0.01), HDL cholesterol (R=−0.21, p=0.006), triglicerides (R=0.3, p<0.0001), platelet count (R=0.23, p=0.002), fasting insulin (R=0.22, p=0.004) and c-peptide (R=0.26, p=0.0005). There was no significant difference in chemerin levels between patients with carotid atherosclerosis (n=93) and patients with normal carotid arteries (n=70), (300±124 vs 263±94 ng/ml, p=0.07). There were no significant associations between chemerin levels and PWV, ABI measurements, SYNTAX score, or 1-year prognosis.
Conclusions
This is the first study to show that in patients with CAD chemerin levels correlate with WBC and with android fat tissue mass. Additionally, chemerin levels positively correlated with other inflammation or insulin resistance markers, and with unfavourable lipid profile.

Abstract
BACKGROUND The highest priority in preventive cardiology is given to patients with established coronary artery disease (CAD). The aim of the study was to assess the current implementation of the guidelines for secondary prevention in everyday clinical practice by evaluating control of the main risk factors and the cardioprotective medication prescription rates in patients following hospitalization for CAD. METHODS Fourteen departments of cardiology participated in the study. Patients (aged ≤ 80 years) hospitalized due an acute coronary syndrome or for a myocardial revascularization procedure were recruited and interviewed 6-18 months after the hospitalization. RESULTS Overall, 947 patients were examined 6-18 months after hospitalization. The proportion of patients with high blood pressure (≥ 140/90 mmHg) was 42%, with high low-density lipoprotein cholesterol (LDL-C ≥ 1.8 mmol/L) 62%, and with high fasting glucose (≥ 7.0 mmol/L) 22%, 17% of participants were smokers and 42% were obese. The proportion of patients taking an antiplatelet agent 6-18 months after hospitalization was 93%, beta-blocker 89%, angiotensin converting enzyme inhibitor or sartan 86%, and a lipid-lowering drug 90%. Only 2.3% patients had controlled all the five main risk factors well (non-smoking, blood pressure < 140/90 mmHg, LDL-C < 1.8 mmol/L and glucose < 7.0 mmol/L, body mass index < 25 kg/m2), while 17.9% had 1 out of 5, 40.9% had 2 out of 5, and 29% had 3 out of 5 risk factors uncontrolled. CONCLUSIONS The documented multicenter survey provides evidence that there is considerable potential for further reductions of cardiovascular risk in CAD patients in Poland. A revision of the state funded cardiac prevention programs seems rational.

Independent Impact of Gynoid Fat Distribution and Free Testosterone on Circulating Levels of N-Terminal Pro-Brain Natriuretic Peptide (NT-proBNP) in Humans. J Clin Med 2019; 9:jcm9010074. [PMID: 31892185 PMCID: PMC7020069 DOI: 10.3390/jcm9010074] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2019] [Revised: 12/23/2019] [Accepted: 12/24/2019] [Indexed: 01/19/2023] Open
Abstract
Background: Natriuretic peptides (NPs), including brain natriuretic peptide (BNP), are neurohormones involved in the regulation of water-sodium balance and the maintenance of cardiovascular homeostasis. A higher concentration of NPs is observed in females, but the mechanism behind this difference has not been fully elucidated. Methods: Randomly chosen 255 volunteers from the general population were examined. Overall, 196 people without severe cardiovascular disease were included (mean age 48 years, 35.7% male). A comprehensive assessment was performed, including anthropometric measurements, N-terminal pro-brain natriuretic peptide (NT-proBNP), total testosterone (TT) and sex hormone-binding globulin (SHBG) concentration, transthoracic echocardiography (ECHO), and body composition analysis by direct dual-energy X-ray absorptiometry (DEXA). The univariate analysis adjusted by the known affecting factors determined which measurements were independently associated with NT-proBNP concentration. Results: NT-proBNP concentration was positively associated with gynoid fat mass, gynoid/total fat (G/TF) mass index, SHBG and negatively with android/gynoid (A/G) fat mass index, TT and calculated free testosterone (CFT) concentrations. Furthermore, body composition parameters remained independently associated with NT-proBNP levels even after adjusting for CFT and SHBG. Conclusion: In the population without severe cardiovascular disease, the NT-proBNP concentration is independently associated with lower availability of testosterone and higher gynoid fat distribution, which may explain higher NPs levels in females.

Abstract
Abstract
Background
Although various echocardiographic parameters of right ventricular dysfunction (RVD) were reported to be of prognostic value in normotensive patients with acute pulmonary embolism (APE), an optimal definition of RVD on echocardiography is missing.
Purpose
We performed a direct comparison of prognostic value of RV/LV ratio, TAPSE, and TRPG/TAPSE for complicated clinical course that included: in-hospital APE related mortality, hemodynamic collapse or rescue thrombolysis.
Methods
Prospective cohorts of APE patients normotensive at admission, managed according to the ESC Guidelines 2014 were merged in a collaborative database. Transthoracic echocardiography was performed at admission, as soon as possible. All studied parameters were available in each patient. AUC in ROC analysis were assessed for each parameter and were compared between them. Multivariable Cox regression analysis was performed to assess the combination of echo-parameters.
Results
Overall, 490 pts were included in the study (229F), aged 64±18 years. Clinical endpoint occurred in 31 pts including 8 APE related deaths. AUC for SAE of RV/LV, TAPSE and TRPG/TAPSE were similar (Figure 1). TAPSE <16mm compared to other echo-parameters showed the highest PPV and NPV (Table 1). Cox regression analysis including SBP, HR, age, elevated troponin and echo-parameters showed that only blood pressure, RV/LV >1 and TAPSE <16mm were identified as independent predictors of outcome (HR 0.98 (95% CI: 0.96–0.99), p=0.03; 2,53 (95% CI: 1.2–5.7), p<0.03 and 3,76 (95% CI: 1.74–8.11), p<0.001).
Table 1. Predictive values of proposed cut offs of echocardiographic parameters Parameter Sensitivity Specificity PPV NPV TAPSE <16mm 52% 85% 18% 96% RV/LV >1.0 74% 63% 12% 95% TAPSE<20 & TRPG/TAPSE >4.5 10% 94% 10% 94%
Figure 1
Conclusions
Although all TAPSE, RV/LV ratio and TRPG/TAPSE showed similar performance for prognosticating of in-hospital outcome in normotensive PE patients, TAPSE<16mm showed the highest predictive value for identification of patients at risk of complicated clinical course.

The impact of metalloestrogens on the physiology of male reproductive health as a current problem of the XXI century. JOURNAL OF PHYSIOLOGY AND PHARMACOLOGY 2019; 70. [PMID: 31539881 DOI: 10.26402/jpp.2019.3.02] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Subscribe] [Scholar Register] [Received: 05/10/2019] [Accepted: 06/28/2019] [Indexed: 11/03/2022]
Abstract
In the XXIst century in highly developed countries, progressively decreasing male reproductive potential is indicated. In recent years epidemiological studies indicate the deterioration of semen parameters: reduction of ejaculate volume, sperm count, and mobility, as well as abnormalities in their morphology. Male infertility can result from many different agents, such as: anatomical or genetic abnormalities, systemic or neurological diseases, infections, trauma, iatrogenic injury, gonadotoxins and development of sperm antibodies and lifestyle (especially obesity, heat and tobacco smoking). It is well documented that adverse changes in male fertility also seem to be associated with environmental exposure to different substances, especially endocrine active factors, known as xenoestrogens, and among these metal ions, known as metalloestrogens, are very important. The role of some metalloestrogens in various diseases, both in women and men, is known and particularly well-proven in women, but still little is known about their role in the regulation of male reproductive potential. Thus we decided to analyse the available information exploring this problem. The review was carried out using the Medline and Google Scholar databases, using the keywords: xenoestrogens, metalloestrogens, male fertility, semen quality, male reproductive potential, mechanisms of metalloestrogen action, environmental pollution and the name of the particular metal. Articles published between 2000 - 2019 have been taken into account, including human and vertebrate animal studies and cell lines. The aim of this review is to discuss the role and mechanisms of action of fifteen metalloestrogens in the human organism, as well as in animal models, and cell cultures, paying special attention to their influence on the physiology of male reproductive health, according to the current state of knowledge. The role of certain metals in human reproduction is still poorly investigated and for some of them only single studies are available. Many factors in our daily lives have a significant impact on male fertility, therefore education is necessary on the threats and how they may be eliminated as far as possible.

The strengths and weaknesses of non-invasive parameters obtained by echocardiography and cardiopulmonary exercise testing in comparison with the hemodynamic assessment by the right heart catheterization in patients with pulmonary hypertension. Adv Med Sci 2017; 62:39-44. [PMID: 28187374 DOI: 10.1016/j.advms.2016.06.001] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2015] [Revised: 05/08/2016] [Accepted: 06/02/2016] [Indexed: 11/27/2022]
Abstract
PURPOSE Pulmonary hypertension (PH) diagnosis requires invasive assessment by right heart catheterization (RHC), but screening and monitoring are performed using non-invasive methods: echocardiography and cardiopulmonary exercise testing (CPET). The aim of the study was to assess correlations between the parameters obtained in non-invasive testing and RHC in patients with PH of different etiologies. MATERIAL/METHODS The study included 53 medical records of PH patients (32 women) aged 29-81 years. We analyzed correlations between RHC (systolic pulmonary artery pressure (sPAP), diastolic pulmonary artery pressure (dPAP), pulmonary vascular resistance (PVR), cardiac output (CO)) and echocardiographic (tricuspid annular plane systolic excursion (TAPSE), sPAP) and CPET parameters (end-tidal oxygen and carbon dioxide pressures (PetO2, PetCO2), ventilation efficiency (VE/VCO2) slope). RESULTS Echocardiographic estimation correlated well with RHC measurement of sPAP (r=0.65, P<0.001). TAPSE correlated with PVR assessed with thermodilution method (r=-0.5, P=0.005), dPAP (r=-0.53, P=0.002) and CO (r=0.53, P=0.002). PVR assessed with thermodilution and Fick methods showed positive correlation with PetO2 (r=0.74, P<0.001 and r=0.72, P<0.001) and negative correlation with PetCO2 (r=-0.59, P=0.004 and r=-0.64, P=0.002) at the anaerobic threshold. VE/VCO2 slope correlated with dPAP (r=0.43, P=0.04) and PVR calculated with both methods (r=0.52, P=0.01 and r=0.52, P=0.02). CONCLUSIONS Simple cardiac function indicators obtained by commonly used non-invasive methods allow only approximate estimation of the main hemodynamic RHC-derived parameters: sPAP, CO and PVR. Obtained results suggest the relationship between RV dysfunction and ventilation abnormalities in PH patients.

Styrene and ethylene glycol have a synergetic effect on lipid peroxidation that is better protected than repaired by CoQ10. Toxicol In Vitro 2005; 19:581-8.

Abstract
Previous study of a group of 22 workers occupationally exposed to styrene, ethylene glycol and their mixture at a paint and lacquer industry indicated significantly elevated concentration of malondialdehyde with 4-hydroxynonenal (MDA+4-HNE) in the blood plasma, successfully decreased with coenzyme Q10 (CoQ10) supplementation. The aim of present study is to evaluate whether the exposure to styrene or/and ethylene glycol could be responsible for the increase in MDA level. The mechanism of a single solvent action and the mixture was examined, specially whether it is connected with hydroxyl radical (*OH) generation. It was also investigated whether coenzyme Q10 could be considered as a protective (given before the solvents) or repairing (given after the solvents) agent in oxidative stress caused by the solvents. The results indicate that ethylene glycol nor styrene increase MDA and *OH, but as a mixture give synergetic interaction, elevating MDA and *OH concentration to a statistically significant extent. Coenzyme Q10 at a dose of 3.0 microg/ml only protects, but does not repair increased lipid peroxidation caused by ethylene glycol with styrene. In order to obtain both a protective and repairing effect, a concentration of 12.0 microg/ml CoQ is needed.

Abstract
Recently some reports about the oxidative stress in renal transplant recipients have been published. The role of coenzyme Q10 (CoQ10) as radical scavanger is largely known. The aim of our study was to evaluate the protective role of CoQ10 in renal transplant recipients on lipid peroxidation and lipids parameters, as well as its influence on antioxidant enzymes, neutrophils chemiluminescence and urinary enzymes. The study was performed in 11 long term allograft recipients treated additionally with CoQ10 90 mg/day in three doses, 30 mg each for four weeks. The malonyldialdehyde (MDA) and 4-hydroxynonenal (4-HNE), superoxide dismutase (SOD) and glutathione peroxidase (GPx) and the basic parameters of lipid metabolism such as total cholesterol (TC), high and low density lipoproteins (HDL, LDL), triglycerides (TG), atherogenicity indicators [LDL/HDL; (TC-HDL)/HDL] were evaluated. The chemiluminescence of neutrophils (luminol, fLMP-method) were mesured and the activity of N-acetyl-beta-D-glucosaminidase (NAG), alanylaminopeptidase (AAP), elastase, alpha-1-antitrypsin. All parameters were estimated before and after CoQ10 treatment. Statistically significant changes were noticed with the LDL and atherogenicity indicators (p < 0.01) (decrease) as well as HDL level (p < 0.001) (increase). Also the significant decrease of fMLP stimulated PMNL chemiluminescence (p < 0.05) confirms the antioxidative properties of CoQ10. The significant increase of NAG activity (p < 0.05) can't be the result of nephrotoxic effect, because NAG-B is unchanged. Serum concentration of creatinine and cyclosporine A in renal allograft recipients was unchanged after CoQ10 treatment. The presented date shows that further study with CoQ10 treatment in renal transplant in larger numbers and over longer periods should be considered.

Abstract
Jejunoileal and colonic atresias are a common cause of neonatal intestinal obstruction. Authors present the aetiology, types of atresias, clinical symptoms, diagnostics, surgical treatment, problems of postoperative management and prognosis in the newborns with congenital intestinal atresia. In the years 1992-2000, in the Department of Paediatric Surgery and in the Department of Pathology and Intensive Care of Newborn at the National Research Institute of Mother and Child in Warsaw, 539 newborns were surgically treated (congenital anomalies of gastrointestinal tract, genito-urinary system, central nervous system, defects of abdominal wall and diaphragm). In 21 patients jejunoileal or colonic atresia were confirmed. On the base of the course of treatment the authors analyse prognostic factors: prematurity, certain types of atresia, additional pathology accompanying intestinal defect, necessesity of re-section of the long part of the bowel or multiple anastomosis. Diagnostic and treatment problems in three patients with short bowel syndrome needed additional discussion.

Abstract
The aim of the study was the definition of standard approach to a newborn with gastroschisis. The rules of treatment introduced in 1992 enabled the closure of the abdominal wall primarily in all newborns and made it possible to decrease the mortality considerably. This was achieved despite the fact that we usually did not have influence on time and method of delivery or quality of transportation to our department. In the Department of Pediatric Surgery of Institute Mother and Child, in the years 1992-1997, twenty three newborns with gastroschisis were admitted. The standard approach in all patients was the following: insertion of the catheters to the small bowel through the appenddicocaecostomy and to the large bowel through the rectum, intraoperative irrigation of the meconium (mucosolvan), forceful stretching of the abdominal wall, returning of extraabdominal viscera under control of central venous pressure or middle airway pressure (anesthesiologic control). In the postoperative period all patients routinely had controlled ventilation, administration of analgesic drugs, catecholamines, antibiotics and total parenteral nutrition. Intestinal catheters were gradually removed every day for irrigations of all levels. Oral nutrition was started after the return of effective peristalsis. From 23 treated newborns 16 are alive. 7 children died, 4 of them were resuscitated before operation because of severe general condition. Two patients died because of sepsis in the second month of life, one because of SIDS (sudden infant death syndrome) in the third week of life. Sixteen children are followed up. The development of all children is normal.

Abstract
The influence of coenzyme Q on the lipid parameters in the paint and lacquer industry workers is presented. The examinations were carried out in the group of 24 workers employed at the paint and lacquer production, who received coenzyme Q10 as a chemoprotective agent. Serum concentration of basic lipid parameters: total cholesterol (TC), high density lipoproteins (HDL), low density lipoproteins (LDL), triglycerides (TG); lipid peroxidation products: malonyldialdehyde (MDA) together with 4-hydroxynonenal (4-HNE) and two antioxidant enzymes: superoxide dismutase (SOD) and glutathione peroxidase (GPx) were examined. The above parameters were measured in workers exposed to organic solvents and then after 4 weeks of coenzyme Q treatment. In order to explain, whether the occupational exposure is responsible for the changed level of some parameters, the reference group, not employed in the paint and lacquer industry, was used. The results indicated that the preliminary blood serum concentration of MDA + 4-HNE in workers exposed to organic solvents was significantly elevated in comparison to the control group. Statistically significant decrease in MDA + 4HNE concentration was observed after coenzyme Q treatment what lead to the conclusion that coenzyme Q could be considered as a protective agent against lipid peroxidation in occupational exposure. The changes in other parameters were statistically insignificant.

Abstract
A frequent occurrence of ophthalmoplegia and muscle fatigability in mitochondrial myopathy (MAM) often makes its differential diagnosis from myasthenia rather difficult. Neuromuscular transmission was investigated in 9 patients with MAM, presenting marked fatigability. The aim of the study was to see whether there were any other causes of muscle fatigability in addition to the metabolic factors. Classical electrostimulation as well as the SFEMG, which is very sensitive in detecting neuromuscular transmission disorders, were used. The findings were far from uniform: we found normal neuromuscular transmission in 5 cases, in 3 patients we observed slight abnormalities of neuromuscular transmission, in 1 case neuromuscular transmission disturbances seemed to be of neurogenic origin. Our results allow an assumption that the causes of muscle fatigability in MAM are of a much more complex nature than it has been anticipated. They might depend not only on the metabolic disorders within the muscle fibre itself but also on the impaired function of the peripheral nerve or of the neuromuscular junction. All the mechanisms combined may also play a role, though in individual patients the contribution of particular factors responsible may vary.

Abstract
A comparison of serum, pulmonary tissue and bronchial secretory levels of erythromycin and cyclic--11,12 carbonate of erythromycin (Davercin--Polfa) was carried out in 55 patients with lung cancer. All patients received erythromycin and Davercin 80 hours prior surgery, during which a small fragment of pulmonary tissue was removed for further evaluation. Concentration of both antibiotics was determined microbiologically. Better penetration of Davercin to the pulmonary tissue was found, as well as higher tissue concentration. The study demonstrates the advantage of Davercin over erythromycin in treating bacterial infections of the respiratory system.

Abstract
Systemic carnitine deficiency is an often fatal, but treatable metabolic disorder which should be considered in any child with repeated episodes of a Reye-like syndrome or a cardiomyopathy. A 4-year-old girl with a typical history and clinical findings was successfully treated with oral carnitine. Despite low liver carnitine, ketogenesis upon fasting was normal. Normal muscle function under therapy was associated with unchanged low muscle carnitine levels. Improvement of mitochondrial structure and function was demonstrated by controlled ultrahistochemical studies. A renal carnitine leak, evident from renal clearance studies, may contribute to the pathogenesis of systemic carnitine deficiency.

Abstract
A case of amyotrophic lateral sclerosis was observed developing three months after thymectomy in a woman aged 52 years. The patient had been referred for thymectomy because of myasthenic signs increasing in intensity since 2 years. Myasthenia was confirmed by electrophysiological investigations, and the diagnosis was: myasthenic syndrome and suspected thymoma. During nearly 5 years of follow-up the following observations were made: there was a correlation between thymectomy and the development of ALS syndrome, thymosine administration produced clinical improvement, thymosine administration improved the function of thymus-dependent lymphocytes, thymosine withdrawal (due to non-availability) produced exacerbation of symptoms.

Abstract
The authors report three cases of complications of renal artery embolization in patients with renal carcinoma. In two cases renal artery embolization was followed by paraparesis with loss of sphincter control. In these cases nephrectomy was performed on the side of the neoplasm and neurological disturbances disappeared after pharmacological treatment and rehabilitation. The third patient was not treated surgically. Embolization was followed by development of spinal cord damage at the level Th12. The patient died of neoplastic cachexia and cardiorespiratory failure.

Abstract
Biochemical, light and electron microscopic observations in six human fetuses between the 16th and 34th weeks of gestation and five infants, 1 day to 3 years old, are presented. The results indicate that myelination of the human spinal cord started before the 16th week of gestation, as a considerable amount of myelin is isolated at this time biochemically, and occasionally axons with loose myelin coils are observed in the electron microscope. It is also stressed that morphological studies are insufficient to evaluate the completion time of the myelination process, as it can be shown biochemically that qualitative myelin maturation takes a long time.
