Endometrium development patterns and BMI groups among in vitro fertilization patients; prognostic aspects.

Introduction: The impact of the obesity pandemic on female reproductive capability is a factor that needs to be investigated. In addition, the link between endometrial thickness and in vitro fertilization (IVF) outcomes is contentious. Goal: Our goal was to analyze the association among endometrium development, hormone levels, embryo quality, clinical pregnancy, anamnestic parameters, and body mass index (BMI) in women receiving IVF treatment. Patients and methods: 537 participants undergoing IVF/ICSI cycles with successful oocyte retrieval were enrolled. Subjects were divided into four BMI based groups: underweight (UW; n=32), normal weight (NW; n=324), overweight (OW; n= 115), obesity (OB; n=66). Anthropometric and anamnestic parameters, characteristics of stimulation, endometrial thickness on the day of hCG injection, at puncture, at embryo transfer, FSH, LH, AMH, partner's age and the semen analysis indicators, embryo quality, clinical pregnancy, were recorded and analyzed. Support Vector Machine (SVM) was built to predict potential pregnancies based on medical data using 22 dimensions. Results: In accordance with BMI categories, when examining pregnant/non-pregnant division, the average age of pregnant women was significantly lower in the UW (30.9 ± 4.48 vs. 35.3 ± 5.49 years, p=0.022), NW (34.2 ± 4.25 vs. 36.3 ± 4.84 years, p<0.001), and OW (33.8 ± 4.89 vs. 36.3 ± 5.31 years, p=0.009) groups. Considering FSH, LH, and AMH levels in each BMI category, a statistically significant difference was observed only in the NW category FSH was significantly lower (7.8 ± 2.99 vs. 8.6 ± 3.50 IU/L, p=0.032) and AMH (2.87 ± 2.40 vs. 2.28 ± 2.01 pmol/L, p=0.021) was higher in pregnant women. There were no further statistically significant differences observed between the pregnant and non-pregnant groups across any BMI categories, especially concerning endometrial development. Surprisingly, BMI and weight correlated negatively with FSH (r=-0.252, p<0.001; r=-0.206, p<0.001, respectively) and LH (r= -0.213, p<0.001; r= -0.195, p<0.001) in the whole population. SVM model average accuracy on predictions was 61.71%. Discussion: A convincing correlation between endometrial thickness development and patients' BMI could not be substantiated. However, FSH and LH levels exhibited a surprising decreasing trend with increasing BMI, supporting the evolutionary selective role of nutritional status. Our SVM model outperforms previous models; however, to confidently predict the outcome of embryo transfer, further optimization is necessary.

Not first-line antihypertensive agents, but still effective-The efficacy and safety of imidazoline receptor agonists: A network meta-analysis.

Cardiovascular disorders are the leading cause of death in the world. Many organ diseases (kidney, heart, and brain) are substantially more prone to develop in people with hypertension. In the treatment of hypertension, first-line medications are recommended, while imidazoline receptor agonists are not first-line antihypertensives. Our goal was to conduct a network meta-analysis to assess the efficacy and safety of imidazoline receptor agonists. The meta-analysis was performed following the PRISMA guidelines using the PICOS format, considering the CONSORT recommendations. Studies were collected from four databases: PubMed, Cochrane Library, Web of Science, and Embase. A total of 5960 articles were found. After filtering, 27 studies remained eligible for network meta-analysis. Moxonidine reduced blood pressure in sitting position statistically significantly after 8 weeks of treatment (SBP MD: 23.80; 95% CI: 17.45-30.15; DBP MD: 10.90; 95% CI: 8.45-13.35) compared to placebo. Moreover, moxonidine reduced blood pressure more effectively than enalapril; however, this difference was not significant (SBP MD: 3.10; 95% CI: -2.60-8.80; DBP MD: 1.30; 95% CI: -1.25-3.85). Dry mouth was experienced as a side effect in the case of all imidazoline receptor agonists. After 8 weeks of treatment, the appearance of dry mouth was highest with clonidine (OR: 9.27 95% CI: 4.70-18.29) and lowest with rilmenidine (OR: 6.46 95% CI: 0.85-49.13) compared to placebo. Somnolence was less frequent with moxonidine compared to rilmenidine (OR: 0.63 95% CI: 0.17-2.31). Imidazoline receptor agonists were nearly as effective as the first-line drugs in the examined studies. However, their utility as antihypertensives is limited due to their side effects. As a result, they are not first-line antihypertensives and should not be used in monotherapy. However, in the case of resistant hypertension, they are a viable option. According to our findings, from the point of view of safety and efficacy, moxonidine appears to be the best choice among imidazoline receptor agonists.

A three-month physical training program improves cardiovascular autonomic function in patients with metabolic syndrome with and without diabetes - a pilot study.

Introduction: Vascular complications and neuropathy may develop in the presence of metabolic syndrome. The aim of our study was to measure the cardiovascular autonomic function following physical training in patients with metabolic syndrome with and without diabetes. Subjects and methods: 56 patients with metabolic syndrome (32 men/24 women, 40 non-diabetic patients (NDMetS)/16 diabetic patients (DMetS) [mean ± SD]: age: 50.35 ± 8.03 vs. 56.8 ± 9.30 years, p=0.023; baseline BMI: 32.2 ± 7.03 vs. 32.8 ± 5.94 kg/m2, p=0.739) were involved in our study. All tests and measurements were carried out before and following a 3-month physical training period. Autonomic function was assessed by means of five standard cardiovascular reflex tests. ECG repolarization parameters, including short-term QT variability and stress-ECG were also measured. Results: In the whole population, Valsalva-ratio (VR) and the autonomic score (AS) improved following training (VR: 1.49 ± 0.24 vs. 1.64 ± 0.34, p=0.001; AS: 2.05 ± 1.73 vs. 1.41 ± 1.36, p=0.015) accompanied by the significant decrease of the systolic (150.3 ± 16.12 vs. 134.1 ± 16.67 mmHg, p<0.001) and diastolic (90.64 ± 12.8 vs. 82.79 ± 11.1 mmHg, p<0.001) blood pressure. An improvement in VR was detected in NDMetS patients following training (1.51 ± 0.24 vs. 1.67 ± 0.31, p= 0.002). No significant changes could be detected in autonomic tests' results in the DMetS patient group following training. The applied exercise training program did not lead to significant changes in ECG repolarization. The stress-ECG test in the whole study population yielded a significant increase in the test duration (12.9 ± 3.76 vs. 15.1 ± 2.96 min, p<0.001) and in the test load (10.5 ± 2.78 vs. 11.6 ± 2.39 MET, p<0.001). The load capability improved significantly in both subgroups: 11.1 ± 2.04 vs. 12.1 ± 1.82, (p<0.001) and 9.0 ± 3.64 vs. 10.4 ± 3.05, (p=0.033) in subpopulations of NDMetS and DMetS, respectively. The DMetS patients achieved a significantly lower MET score at baseline (p=0.039) and following training (p=0.044) in comparison to the NDMetS patients. Conclusion: The three-month exercise program improved the Valsalva-ratio and the AN score in the MetS patients, that is potentially protective against cardiovascular events. The training had some beneficial effect on blood pressure and the results of the stress-ECG tests in both groups. The absence of significant change in the reflex tests in DMetS group reflects an impaired adaptation compared to the NDMestS group.

[Left ventricular deformation: similarities and dissimilarities in elite sport activity- and acromegaly-related abnormalities. Results from the three-dimensional speckle-tracking echocardiographic MAGYAR-Sport and MAGYAR-Path Studies] / Bal kamrai deformitás: az aktív élsporthoz és az acromegaliához kötheto eltérések hasonlóságai és különbségei. Eredmények a háromdimenziós speckle-tracking echokardiográfiás MAGYAR-Sport és MAGYAR-Path Tanulmányokból

INTRODUCTION: Acromegaly is a chronic endocrine disorder, which produces a significant amount of human growth hormone and consequently insulin-like growth factor in adulthood due to a tumor in the pituitary gland. If left untreated, it can have a significant effect on the cardiovascular system. It is also known that elite sport activity is also associated with physiologic cardiac transformation, the so-called athletes' heart, in which volumetric and functional adaptation of the heart cavities can be observed. OBJECTIVE: In accordance with the above facts, the question may rightly arise as to what differences can be observed in left ventricular morphology and function in acromegaly, and what similarities and dissimilarities do the obtained results show compared to the values of healthy non-athlete adults compared to the values of the left ventricle of young elite athletes. METHOD: The present study comprised 21 elite athletes playing high dynamic sports (mean age: 31.2 ± 6.4 years, 13 males) and 18 acromegaly patients (mean age: 47.9 ± 8.9 years, 9 males). Their results were compared to those of 22 negative controls (mean age: 47.7 ± 10.6 years, 13 males). RESULTS: Left ventricle is dilated, but its function is preserved in both elite athletes and patients with acromegaly. While increased longitudinal and circumferential left ventricular strains could be seen in elite athletes primarily due to the more pronounced contractility of left ventricular apical segments, increased radial left ventricular strain was detected in acromegaly due to increased function of the left ventricular basal region. Left ventricular rotational mechanics show different patterns as well: while basal left ventricular rotation is decreased in elite athletes, apical left ventricular rotation showed a reduction leading to the significant deterioration of left ventricular twist in acromegaly. CONCLUSION: Both elite athletes playing high dynamic sports and acromegaly patients have dilated left ventricle, more pronounced regional left ventricular contractility and left ventricular rotational abnormalities with differences in nature and extent of these alterations as compared to those of non-sporting healthy subjects.

Left ventricular deformation in athletes playing sports with high dynamics-insights from the three-dimensional speckle-tracking echocardiographic MAGYAR-Sport Study.

Background: Earlier results suggest the role of speckle-tracking echocardiography (STE)-derived left ventricular (LV) strains in screening and could help better understanding of adaptation to exercise. The present retrospective cohort study aimed to investigate three-dimensional STE-derived LV strains representing its deformation in athletes playing sports with high dynamics with different grades of static components of their training. Methods: The study consisted of 67 athletes (mean age: 23.6±6.4 years, 39 males). This group of athletes was further divided into the following groups: Group C.I. (high dynamic/low static) (n=12), Group C.II. (high dynamic/moderate static) (n=22) and Group C.III. (high dynamic/high static) (n=33). The control group comprised 83 age- and gender-matched non-athletic healthy volunteers (mean age: 23.6±3.2 years, 50 males). Results: Global LV longitudinal strain (LS) representing LV lengthening or shortening (-18.5%±3.0% vs. -16.3%±2.3%, P<0.05), LV circumferential strain (CS) representing LV widening or narrowing (-29.9%±5.2% vs. -28.1%±4.8%, P<0.05) and LV area strain (AS; combination of LS and CS; -43.7%±5.4% vs. -40.9%±4.8%, P<0.05) were increased in elite athletes as compared to those of non-athlete controls. All apical LV strains proved to be increased in all athletes with enhanced basal radial strain (RS, representing LV thickening and thinning) and LS and midventricular LS, AS and 3D strain (3DS, combination of RS, LS and CS). Conclusions: Increased LV-LS, LV-CS and LV-AS represents enhanced LV deformation in longitudinal and circumferential directions in athletes playing sports with high dynamics. This enhancement is not related to the grade of the static component of training. Some regional differences in LV strains could be detected.

Physiological and psychological effects of a 12-week home-based telemonitored training in metabolic syndrome.

Background: Metabolic Syndrome (MetS) increases the risk of cardiovascular diseases (CVD) and affects around one fourth of the population worldwide. In the prevention and treatment regular exercise trainings are inevitable. Providing personal supervision in out/inpatient care settings for such a large target population challenges the healthcare systems, but using telemonitoring of the home-performed trainings could be a promising and widely available option. Objectives: The aim of this study was to evaluate the physiological and psychological effects of a 12-week home-based physical training program, telemonitored by widely available fitness devices on parameters of MetS patients. Methods: A total of 55 MetS patients (mean age 49.19 ± 7.93 years) were involved in the study. They were asked to perform 3-5 sessions of exercise activity (min. 150 min) each week for 12 weeks. Trainings were monitored off-line by heart rate sensors, a fitness application and a cloud-based data transfer system. Physiotherapists supervised, coached, and feedback the trainings through an online coach system. We investigated different anthropometric parameters, maximum exercise and functional capacity levels, laboratory parameters, the level of depression, insomnia, vital exhaustion, and wellbeing as well. Results: The average weekly training time was 152.0 ± 116.2 min. Out of the 55 participants who completed the program, 22 patients (40%) performed the recommended 150 min or more weekly. Patients showed statistically significant changes in: all the measured waist and hip circumferences; 6-min walk distance (6MWD; from 539.69 ± 78.62 to 569.72 ± 79.96 m, p < 0.001); maximal exercise capacity (11.02 ± 2.6 to 12.14 ± 2 MET, p < 0.001), stress-electrocardiogram duration time (13.74 ± 3.29 to 15.66 ± 2.64 min, p < 0.001); body weight (98.72 ± 21.7 to 97.45 ± 21.76 kg, p = 0.004); high-density lipoprotein cholesterol (n = 45, 1.28 ± 0.31 to 1.68 ± 0.36 mmol/L, p < 0.001); fasting plasma glucose (FPG; n = 47, 6.16 ± 1.26 to 5.44 ± 1.31 mmol/L, p = 0.001); glycated hemoglobin A1c (HbA1c; n = 41, 6.22 ± 0.68 to 5.87 ± 0.78%, p = 0.01). Out of the 55 patients who finished the program 38 patients (70%) completed all the psychological questionnaires. We found statistically significant decrease of the overall scores of the Maastricht Vital Exhaustion Questionnaire, from 3.37 ± 2.97 points to 2.63 ± 2.70 points (p < 0.05) and a significant increase of the overall scores of the WHO Wellbeing Scale from 9.92 ± 2.59 points to 10.61 ± 2.76 points (p < 0.05). We have not found any statistically significant changes in the scores of the Beck Depression Inventory and the Athens Insomnia Scale. Conclusion: A 12-week home-based telemonitored training supported by an affordable, commonly available device system produces positive, statistically significant changes in many core components in MetS patients. Telemonitoring is a cheap method for coaching and feeding back the home-based interventions.

Effect of ivabradine in heart failure: a meta-analysis of heart failure patients with reduced versus preserved ejection fraction.

In clinical trials of heart failure reduced ejection fraction (HFrEF), ivabradine seemed to be an effective heart rate lowering agent associated with lower risk of cardiovascular death. In contrast, ivabradine failed to improve cardiovascular outcomes in heart failure preserved ejection fraction (HFpEF) despite the significant effect on heart rate. This meta-analysis is the first to compare the effects of ivabradine on heart rate and mortality parameters in HFpEF versus HFrEF. We screened three databases: PubMed, Embase, and Cochrane Library. The outcomes of these studies were mortality, reduction in heart rate, and left ventricular function improvement. We compared the efficacy of ivabradine treatment in HFpEF versus HFrEF. Heart rate analysis of pooled data showed decrease in both HFrEF (-17.646 beats/min) and HFpEF (-11.434 beats/min), and a tendency to have stronger bradycardic effect in HFrEF (p = 0.094) in randomized clinical trials. Left ventricular ejection fraction analysis revealed significant improvement in HFrEF (5.936, 95% CI: [4.199-7.672], p < 0.001) when compared with placebo (p < 0.001). We found that ivabradine significantly improves left ventricular performance in HFrEF, at the same time it exerts a tendency to have improved bradycardic effect in HFrEF. These disparate effects of ivabradine and the higher prevalence of non-cardiac comorbidities in HFpEF may explain the observed beneficial effects in HFrEF and the unchanged outcomes in HFpEF patients after ivabradine treatment.

Peripheral and Autonomic Neuropathy Status of Young Patients With Type 1 Diabetes Mellitus at the Time of Transition From Pediatric Care to Adult-Oriented Diabetes Care.

Introduction: The prevalence of neuropathic lesions in young patients with type 1 diabetes mellitus (T1DM) at the time of transition from pediatric care to adult-oriented diabetes care is poorly studied. A comparative study with healthy volunteers to assess the possible neuropathic condition of this special population and to identify the potential early screening needs has not been performed yet. The results may provide important feedback to pediatric diabetes care and a remarkable baseline reference point for further follow up in adult diabetes care. Patients and Methods: Twenty-nine young patients with T1DM [age: 22.4 ± 2.9 years; HbA1c: 8.5 ± 2.1%, diabetes duration: 12.2 ± 5.8 years; (mean ± SD)] and 30 healthy volunteers (age: 21.5 ± 1.6 years; HbA1c: 5.3 ± 0.3%) were involved in the study. Autonomic function was assessed by standard cardiovascular reflex tests. Complex peripheral neuropathic testing was performed by Neurometer®, Neuropad®-test, Tiptherm®, Monofilament®, and Rydel-Seiffer tuning fork tests. Results: T1DM patients had significantly higher diastolic blood pressure than controls (80 ± 9 vs. 74 ± 8 mmHg, p < 0.01), but there was no significant difference in systolic blood pressure (127 ± 26 vs. 121 ± 13 mmHg). Cardiovascular reflex tests had not revealed any significant differences between the T1DM patients and controls. No significant differences with Neurometer®, Neuropad®-test, and Monofilament® were detected between the two groups. The vibrational sensing on the radius on both sides was significantly impaired in the T1DM group compared to the controls with Rydel-Seiffer tuning fork test (right: 7.5 ± 1.0 vs. 7.9 ± 0.3; left: 7.5 ± 0.9 vs. 7.9 ± 0.3, p < 0.05). The Tiptherm®-test also identified a significant impairment in T1DM patients (11 sensing failures vs. 1, p < 0.001). In addition, the neuropathic complaints were significantly more frequently present in the T1DM patient group than in the controls (9 vs. 0, p < 0.01). Conclusion: In this young T1DM population, cardiovascular autonomic neuropathy and cardiac morphological alterations could not be found. However, Rydel-Seiffer tuning fork and Tiptherm®-tests revealed peripheral sensory neurological impairments in young T1DM patients at the time of their transition to adult diabetes care.

Left ventricular rotational mechanics in elite athletes doing high dynamic sports. Insights from the 3D speckle-tracking echocardiographic MAGYAR-Sport Study.

BACKGROUND: In normal circumstances while left ventricular (LV) apex rotates counterclockwise, LV base has a clockwise movement at the same time. This sort of towel-wringing-like movement is called LV twist. The present study was designed to test whether differences in LV rotational mechanics could be detected in elite athletes doing high dynamic sports with different static components in their training. METHODS: The subject group comprised 80 elite sportsmen. The following groups were created regarding their physical activity: group CI (high dynamic/low static)(N.=13, mean age: 24.0±5.1 years, group CII (high dynamic/moderate static)(N.=23, mean age: 24.6±7.7 years) and group CIII (high dynamic/high static)(N.=34, mean age: 22.8±6.0 years). Their results were compared to 67 age- and gender-matched non-athletic healthy controls (mean age: 24.0±5.1 years). Three-dimensional speckle-tracking echocardiography was used for the evaluation of LV rotational abnormalities. RESULTS: Reduced LV basal rotation was seen in group CII and CIII subjects compared to the control group (-4.31±1.82 degrees vs. -3.17±2.81 degrees and -2.88±1.88 degrees, P<0.05 and P<0.05, respectively). It was accompanied with LV twist reduction in groups CII and CIII subjects compared to the control group (14.0±3.4 degree vs. 11.3±4.3 degrees and 11.5±4.1 degrees, P<0.05 and P<0.05, respectively). None of the elite athletes showed absence of LV twist called as LV "rigid body rotation." CONCLUSIONS: Significant LV rotational abnormalities including reduced LV basal rotation and twist could be detected in elite athletes doing high dynamic sports with moderate/high static components in their training.
