RESUMEN
Background: The wearable cardioverter defibrillator (WCD), (LifeVest, ZOLL, Pittsburgh, PA, USA) is a medical device designed for the temporary detection and treatment of malignant ventricular tachyarrhythmias. WCD telemonitoring features enable the evaluation of the physical activity (PhA) of the patients. We sought to assess with the WCD the PhA of patients with newly diagnosed heart failure. Methods: We collected and analyzed the data of all patients treated with the WCD in our clinic. Patients with newly diagnosed ischemic, or non-ischemic cardiomyopathy and severely reduced ejection fraction, who were treated with the WCD for at least 28 consecutive days and had a compliance of at least 18â h the day were included. Results: Seventy-seven patients were eligible for analysis. Thirty-seven patients suffered from ischemic and 40 from non-ischemic heart disease. The average days the WCD was carried was 77.3 ± 44.6 days and the mean wearing time was 22.8 ± 2.1â h. The patients showed significantly increased PhA measured by daily steps between the first two and the last two weeks (Mean steps in the first 2 weeks: 4,952.6 ± 3,052.7 vs. mean steps in the last 2 weeks: 6,119.6 ± 3,776.2, p-value: < 0.001). In the end of the surveillance period an increase of the ejection fraction was observed (LVEF-before: 25.8 ± 6.6% vs. LVEF-after: 37.5 ± 10.6%, p < 0.001). Improvement of the EF did not correlate with the improvement of PhA. Conclusion: The WCD provides useful information regarding patient PhA and may be additionally utilized for early heart failure treatment adjustment.
RESUMEN
AIM: To investigate the value of prospective in-hospital registry data and the impact of an infectious endocarditis heart team approach (IEHT) on improvement in quality of care and monitor outcomes in hospitalized patients with IE. METHODS: Between December 2014 and the end of 2019, 160 patients were hospitalized in one centre with the definite diagnosis of infectious endocarditis (IE) and entered in a prospective registry. From 2017, an IEHT was introduced. Propensity score matching was used to assess the impact of an IEHT approach on clinical outcomes. RESULTS: Median age was 72.5 y (62.75-80.00), diabetes was present in 33.1%, chronic kidney disease in 27.5%, COPD in 17.5%, and a history of ischaemic heart disease in 30.6%. Prosthetic valve IE was observed in 43.8% and device-related IE in 16.9% of patients. Staphylococcus (37.5%) was the most frequent pathogen followed by streptococcus (24.4%) and enterococcus (23.1%). Overall, 30-day and 1-year mortality were 19.4% and 37.5%, respectively. The introduction of prospective data collection and IE heart team was associated with a trend towards reduction of adjusted 1-year mortality (26.5% IEHT vs. 41.2% controls, p = 0.0699). An IEHT clinical decision-making approach was independently associated with a shorter length of stay (p = 0.04). CONCLUSIONS: Use of a prospective registry of IE coupled with a heart team approach was associated with more efficient patient management and a trend towards lower mortality. Prospective data collection and dedicated IEHT have the potential to improve patient care and clinical outcomes.
RESUMEN
Fractional flow reserve (FFR) measurement was compared to dobutamine stress echocardiography (DSE) instable angina (SA) with stable coronary lesion (s) (SCL (s) ) in a few trials; however, similar comparisons in patients with acute coronary syndrome (ACS) with non-culprit lesion (s) (NCL (s) ) are lacking. Our objectives were to prospectively evaluate the diagnostic performance of FFR with two different cutoff values (< 0.80 and < 0.75) relative to DSE in moderate (30%-70% diameter stenosis) NCLs (ACS group) and to compare these observations with those measured in SCLs (SA group). One hundred seventy-five consecutive patients with SA (n = 86) and ACS (n = 89) with 225 coronary lesions (109 SCLs and 116 NCLs) were enrolled. In contrast to the ACS cohort in SA patients, normal DSE was associated with higher FFR values compared to those with abnormal DSE (P = 0.051 versus P = 0.006). In addition, in the SA group, a significant correlation was observed between DSE (regional wall motion score index at peak stress) and FFR (r = -0.290; P = 0.002), whereas a similar association was absent (r = -0.029; P = 0.760) among ACS patients. In the SA group, decreasing the FFR cutoff value (< 0.80 versus < 0.75) improved the concordance of FFR with DSE (70.6% versus 81.7%) without altering its discriminatory power (area under the curve; 0.68 versus 0.63; P = 0.369), whereas in the ACS group, concordance remained similar (69.0% versus 71.6%) and discriminatory power decreased (0.62 versus 0.51; P = 0.049), respectively. In conclusion, lesion-specific FFR assessment may have different relevance in patients with moderate NCLs than in patients with SCLs.

Our objective was to describe the long-term effects of endoscopic mitral valve (MV) repair on outcome in patients with heart failure with preserved ejection fraction (HFpEF) and atrial functional mitral regurgitation (AFMR). In patients with HFpEF, even mild AFMR has been associated with poor outcome. The study population consisted of consecutive patients with HFpEF (left ventricular ejection fraction (LVEF) ≥ 50%, H2FPEF score ≥ 5) and AFMR, who underwent isolated, minimally invasive endoscopic MV repair (MVRepair group) (n = 131) or remained on standard of care (StanCare group) (n = 139). Patients with coronary artery disease or organic mitral regurgitation (MR) were excluded. Patients were matched using inverse probability of treatment weighting. Endpoints were all-cause mortality and a composite of all-cause mortality and HFpEF readmissions. The median follow-up was 5.03 years (interquartile range (IQR) 2.6-7.9 years). In the MVRepair group, the perioperative, 30-day, 1-year, and 5-year mortality were 0, 1%, 1%, and 12%, respectively. Additionally, 13 (10%) patients were readmitted for worsening HFpEF, while 2 (1%) individuals underwent redo MV surgery for recurrent MR. MVRepair compared with StanCare showed 21-29% (Standard Error (SE) 6-8%) and 19-26% (SE 6-8%) absolute risk reduction of all-cause mortality and HFpEF readmissions, respectively (all p < 0.05). MVRepair emerged as the strongest independent predictor of all-cause mortality (Hazard Ratio (HR) 0.16, 95% (Confidence Interval (CI) 0.07-0.34, p < 0.001) and HFpEF readmissions (HR 0.21, 95% CI 0.09-0.51, p < 0.001). At 5-year follow-up, in the MVRepair group, a total of 88% were alive and 80% were alive without readmission for HFpEF. We can conclude that endoscopic MV repair is associated with low perioperative mortality as well as high long-term efficacy, and appears to improve clinical outcome in patients with AFMR and HFpEF.
RESUMEN
Rationale: The relationship of functional parameters such as lung mechanics, chest kinematics, metabolism and peripheral and respiratory muscle function with the level of exercise tolerance remains a controversial subject. While it has been previously shown that pulmonary rehabilitation is capable of improving exercise tolerance in patients afflicted by COPD, as expressed by values of 6-minute walking test (6MWT), the degree of contribution to this change by each of the aforementioned parameters remains unclear. Aims: To investigate the correlation between changes in exercise capacity and other functional markers following pulmonary rehabilitation in COPD and to determine which parameters are more closely related to improvements of exercise tolerance. Materials and methods: Three hundred and twenty-seven patients with COPD (with average, 95% CI for forced expiratory volume in the first second [FEV1]: 45% [25%-83%] predicted, age: 64 [48-80] years, and BMI: 27 [13.5-40.4] kg/m2) participated in this study. Thirty percent of the patients had pulmonary hypertension as comorbidity. Patients underwent a pulmonary rehabilitation program with 20-30 minutes sessions two to three times per day for 4 weeks. The program was composed of chest wall-stretching, controlled breathing exercises, and a personalized training schedule for cycling and treadmill use. Measurements of 6MWT, lung function, chest wall expansion, grip strength, maximal inspiratory pressure, and breath holding time were taken. The Body mass index, airflow Obstruction, Dyspnea and Exercise capacity (BODE-index), body mass index [BMI], FEV1, 6MWT, modified Medical Research Dyspnea Scale score, and an alternative scale score (for BMI, FEV1, 6MWT, and COPD Assessment Test) were calculated. Results: Rehabilitation resulted in a generalized improvement in 6MWT among patients (average: 360 [95% CI: 178-543 m] vs average: 420 [95% CI: 238-601 m], p<0.05). Improvements in exercise tolerance were found to be most closely associated with changes in composite BODE-index (R2=-0.6), Alternative Scale (R2=-0.56), dyspnea score (modified Medical Research Dyspnea Scale R2=-0.54), and health status (COPD Assessment Test R2=-0.4, p<0.05). In addition, improvements in exercise tolerance were found to moderately correlate with improvements in inspiratory vital capacity (IVC, R2=0.34, p<0.05). Post-rehabilitation changes in IVC displayed a connection with grip strength (R2=0.6) and chest expansion (R2=0.48). Conclusion: Enhancements in exercise tolerance had correlation with changes in IVC, BODE-index, and the new Alternative Scale. However, comprehensive assessment needs to include considerations of chest kinematics and peripheral and respiratory muscle function as well.

Chronic obstructive pulmonary disease (COPD) is associated with the accelerated aging of the lung. The protein klotho has been implicated in longevity, and there is some evidence that it might be involved in the pathomechanism of chronic respiratory diseases. Therefore, we aimed to examine whether the clinical condition of COPD patients is reflected in plasma klotho concentration. As plasma concentration of the protein is modulated by physiological factors that are generally improved during pulmonary rehabilitation, we hypothesized that a complex rehabilitation program may alter plasma klotho concentration. Blood samples were taken from 31 stable COPD patients. Clinical parameters such as respiratory function, 6-minute walking distance (6MWD), impact of disease (CAT), dyspnea, grip strength, chest expansion and breath holding time, smoking history, and body mass index (BMI) were evaluated. 19 patients who participated in a 3-week inpatient rehabilitation program had blood sample collection on the first, third, and last days of the program and had the above functional measurements before and after rehabilitation. Plasma klotho concentration was assessed by enzyme-linked immunosorbent assay. Klotho levels showed no correlation with clinical parameters (FEV1%, 6MWD, grip strength, CAT, smoking history, p > 0.05). Coefficient of variation of klotho measurements was 4.5% between Day 1 and Day 3. Although the rehabilitation resulted in significant improvements in 6MWD, CAT, grip strength, and chest expansion, klotho levels did not change significantly (510.1 ± 149.9 vs. 504.2 ± 139.8 pg/ml, p > 0.05). Plasma klotho concentration can be reliably measured in stable COPD; however, its levels are not correlated with clinical parameters of patients. Despite functional improvement, klotho level remains unchanged during the rehabilitation program.

We assessed contamination in the Upper Tisza region (Hungary, Central Europe), analyzing the elemental concentrations in sediment cores of oxbows. Our hypothesis was that the metal contamination which occurred in the year 2000 and which came from the mining area in Transylvania (Romania) may be detected even 15 years after the contamination, based on the vertical profile of sediment cores. Sediment cores were collected from five oxbows, and the following elements were measured with microwave plasma-atomic emission spectrometry (MP-AES): Cu, Cr, Ba, Fe, Mn, Pb, Sr, and Zn. Among the oxbows studied, there was one protected oxbow, three were used for fishing, and one was contaminated with sewage. Our results indicated that the year of contamination is still observable in the vertical profile of the sediment cores. The pollution index (PI) was used to characterize the sediment enrichment of metal elements in the sediment cores. In the case of Cu, Pb, and Zn, the contamination which originated in the year 2000 was detected in the layers of the sediment cores. The contamination levels of Cu, Pb, and Zn were high or moderate in the studied oxbows. All oxbows were moderately contaminated by Mn, while a moderate level of contamination was found for Fe in the protected oxbow, one fishing oxbow, and the sewage-contaminated oxbow. In the fishing oxbows, a low level of contamination was found for Fe. The contamination level of Sr was low in the protected oxbow and in the two fishing oxbows, while in one of the fishing oxbows and in the sewage-contaminated oxbow, a moderate level of Sr contamination was found. The pollution index scores indicated that the contamination level for Ba and Cr was low in the sediment cores of the oxbows studied. Our results indicated that the contamination of the Tisza River from the mining area in Northern Romania has been continuous and is still ongoing.

Ixodes ricinus is the most important tick species in Europe as it is most widely distributed and transmits the majority of tick-borne zoonotic pathogens. As limited data are available for Hungary, the aim of the present study was to investigate the seasonal timing of questing by I. ricinus and the infection rate of this tick species with all major tick-borne zoonotic pathogens. Monthly collections of I. ricinus were carried out over 3 consecutive years by dragging a blanket in 6 biotopes representing different areas of Hungary. Altogether, 1800 nymphs (300 per collection point) were screened as pooled samples (each of 5 specimens) by PCR-based methods for tick-borne pathogens. I. ricinus larvae, nymphs, and adults had bimodal activity patterns with a major peak in the spring. As newly moulted ticks of all stages are thought to emerge in the autumn of each year, it appears that most newly emerged ticks delayed their questing until the following spring. The minimum prevalence of Borrelia burgdorferi sensu lato was 2.5%. Borr. afzelii, Borr. burgdorferi sensu stricto, Borr. garinii, Borr. lusitaniae, and Borr. valaisiana were identified by hybridization. The minimum infection rate with spotted fever group rickettsiae was 1.9%. Rickettsia helvetica was identified in all biotopes. The minimum prevalence of Anaplasma phagocytophilum, Babesia divergens and Bab. microti was low (0.3-0.5%). Bartonella spp.-, Francisella tularensis-, and TBE virus-specific amplification products were not detected. Relative to the results of comparable studies carried out in the Carpathian Basin, the prevalence of tick-borne pathogens was low in Hungary. This might be attributed to the climatic difference between the lowland areas of Hungary and submountain areas of the surrounding countries involved in the studies.

OBJECTIVES: The aim of this work was to study the tick-borne encephalitis virus (TBEV) infection of goats and the possibilities to prevent human milk-borne infections either by immunizing animals or the heat treatment of milk. METHODS: An experiment was conducted with 20 milking goats. Ten goats (half of them immunized) were challenged with live TBEV and 10 were left uninfected. Clinical signs and body temperatures of the animals were recorded and milk samples were collected daily. The presence of viral RNA and infectious virions in milk were detected by RT-PCR and intracerebral inoculation of suckling mice, respectively. Milk samples containing infectious virions were subjected to various heat treatment conditions and retested afterwards to assess the effect on infectivity. RESULTS: The infected goats did not show any clinical signs or fever compared to uninfected ones. Infectious virions were detected for 8-19 days from the milk samples (genome for 3-18 days by PCR) of infected goats. Immunized goats did not shed the virus. After heat treatment of the milk, the inoculated mice survived. CONCLUSIONS: Goats shed the virus with their milk without showing any symptoms. Human milk-borne infections can be avoided both by immunizing goats and boiling/pasteurizing infected milk.

The presence of WNV in Europe has been well known for decades, although the first human infections and avian outbreaks were diagnosed in Hungary only in 2003. An annual average of 6-8 cases of the neuroinvasive form of WNV infection has been detected in the region since then, but a higher number (17) of WNV associated neuroinvasive disease occurred in 2008. In 2004, a surveillance system was established for monitoring WNV-associated meningo-encephalitis cases in Hungary, but a milder type of illness (with fever, rash and/or influenza like symptoms) is not followed. Fifty-two sera of 45 patients with mild clinical symptoms (fever, exanthema) were tested for anti-WNV antibodies in 2008 in a retrospective study by immunofluorescence test and ELISA. Seven patients had antibodies against WNV, serologic evidence of recent WNV infection was found in 4 out of the 7 patients. Infections could be acquired predominantly in August and in September, which seems to be a risk period for WNV in Hungary. The possibility of a recent WNV infection should be taken into consideration in the occurrence of fever and rush at late summer. Differential diagnosis of exanthematous patients should include WNV serology tests and should be done routinely.

A tick-borne encephalitis outbreak involving 25 patients of 154 exposed persons occurred in Hungary in August 2007. None of the patients had a history of tick-bite, however all of them drank unpasteurized raw goat milk from the same farm. The aim of this study was to identify the goats on the farm which could have spread the infection through their milk. Blood samples were taken from 75 goats on the farm and were examined by various serological methods, namely indirect immunofluorescent assay, hemagglutination inhibition, microneutralization and an ELISA adapted to testing material from goats, to determine antibody levels in the serum. The four methods have proved different levels of specificity. The least specific was the indirect immunofluorescent assay, which showed a low titre in all sera. Comparison of the results of the other three methods indicates that two sera were positive for anti-TBEV IgG and one for anti-TBEV IgM. The goat with the IgM positive serum sample could have been a source of the infected milk. It has been concluded that serological results for goats by the different methods should be compared before final diagnosis because the specificity of methods in use can differ significantly.

BACKGROUND AND OBJECTIVES: Mesenchymal stem cells (MSCs) are promising for use in regenerative medicine. Cytostatics can decrease, but low-power laser irradiation (LPLI) can increase the growth of MSCs. The interaction of LPLI, MSCs and cytostatics is not known. This study investigated the effect of four cytostatics (carboplatin, cytarabine, paclitaxel, vincristine), LPLI, and combination of a cytostatic drug and LPLI on murine MSCs (mMSCs). STUDY DESIGN/MATERIALS AND METHODS: MMSCs were exposed to LPLI (660 nm diode laser; 60 mW output power; range of power density: 76-156 mW/cm(2); range of energy density: 1.9-11.7 J/cm(2)) and/or a cytostatic drug (carboplatin: 2, 10, 50; cytarabine: 0.4, 10, 50; paclitaxel: 0.4, 2, 10; vincristine: 0.02, 0.1, 0.5 microg/ml, respectively). Cell proliferation was measured after 24, 48, or 72 hours incubation. RESULTS: LPLI at 1.9 J/cm(2) dose increased the proliferation rate with 41% after 48 hours. However, 11.7 J/cm(2) LPLI caused 42% inhibition and cytostasis was still detectable after 72 hours. LPLI caused equivalent stimulation in single or in divided doses (3.8 vs. double 1.9 J/cm(2) in a 24-hour period). The cytotoxicity of 50 microg/ml carboplatin was eliminated, the inhibitory power of 0.1 microg/ml vincristine was attenuated by 1.9 J/cm(2) LPLI even 3 days post-treatment (attenuation >10%). The 11.7 J/cm(2) LPLI enhanced the cytotoxicity of 50 microg/ml cytarabine (from 48% to 73%) and 10 microg/ml paclitaxel (from 37% to 78%). Combination of the ineffective 0.4 microg/ml cytarabine or paclitaxel with the inhibitory 11.7 J/cm(2) LPLI exhibited stronger inhibition than the 11.7 J/cm(2) LPLI alone (69% and 69% vs. 42%). CONCLUSIONS: Low energy density of LPLI increases and high energy density of LPLI decreases the proliferation of mMSCs. Furthermore, LPLI can prevent or attenuate some drug's cytotoxicity and amplify others'. The result depends on the applied energy density, on the type and concentration of the cytostatics.

INTRODUCTION: IBD is a systemic disease associated with a number of extraintestinal manifestations (EIM). The author's aim was to determine the prevalence and features of EIM in a large IBD population in Veszprém county in a 25-year follow-up study. PATIENTS AND METHODS: 873 IBD patients were enrolled in the study (UC: 619, m/f: 317/302, age at presentation: 38.3 yrs, disease duration: 11.2 yrs; CD: 254, m/f: 125/129, age at presentation: 32.5 yrs, disease duration: 9.2 yrs). Intestinal, extraintestinal symptoms and laboratory tests were monitored regularly. Any alteration suggesting an EIM was investigated by specialist. RESULTS: A total of 21.3% of patients with IBD patients had EIM (UC: 15.0%, CD: 36.6%). Age at presentation did not affect the likelihood of EIM. Prevalence of EIM was higher in women and in CD, ocular complications and PSC were more frequent in UC. In UC there was an increased tendency of EIM in patients having a more extensive disease. In CD patients colonic location increased the frequency of axial and type-1 peripheral arthritis. In UC positive family history increased the risk of joint (OR: 3.63) complications. Joint complications were more frequent in CD (22.4%) than in UC (10.2%, p < 0.01). PSC was present in 1.6% in UC and 0.8% in CD. Dermatological complications were present in 3.8% in UC and 10.2% in CD, the rate of ocular complications was around 3% in both diseases. Erythema nodosum, pyoderma gangrenosum and uveitis were the most frequent manifestations among them. Rare complications were glomerulonephritis, autoimmune haemolytic anaemia and celiac disease. CONCLUSION: The prevalence of EIM in Hungarian IBD patients was in concordance with data from Western countries. The high number of EIM supports a role for complex follow-up in these patients.

AIM: IBD is a systemic disease associated with a large number of extraintestinal manifestations (EIMs). Our aim was to determine the prevalence of EIMs in a large IBD cohort in Veszprem Province in a 25-year follow-up study. METHODS: Eight hundred and seventy-three IBD patients were enrolled (ulcerative colitis/UC/: 619, m/f: 317/302, mean age at presentation: 38.3 years, average disease duration: 11.2 years; Crohn's disease/CD/: 254, m/f: 125/129, mean age at presentation: 32.5 years, average disease duration: 9.2 years). Intestinal, extraintestinal signs and laboratory tests were monitored regularly. Any alteration suggesting an EIMs was investigated by a specialist. RESULTS: A total of 21.3% of patients with IBD had EIM (UC: 15.0%, CD: 36.6%). Age at presentation did not affect the likelihood of EIM. Prevalence of EIMs was higher in women and in CD, ocular complications and primary sclerosing cholangitis (PSC) were more frequent in UC. In UC there was an increased tendency of EIM in patients with a more extensive disease. Joint complications were more frequent in CD (22.4% vs UC 10.2%, P<0.01). In UC positive family history increased the risk of joint complications (OR:3.63). In CD the frequency of type-1 peripheral arthritis was increased in patients with penetrating disease (P=0.028). PSC was present in 1.6% in UC and 0.8% in CD. Dermatological complications were present in 3.8% in UC and 10.2% in CD, the rate of ocular complications was around 3% in both diseases. Rare complications were glomerulonephritis, autoimmune hemolytic anaemia and celiac disease. CONCLUSION: Prevalence of EIM in Hungarian IBD patients is in concordance with data from Western countries. The high number of EIM supports a role for complex follow-up in these patients.

The majority of the viral hepatitis cases is caused by five hepatitis viruses (A,B,C,D,E). In 1997, TT virus was discovered. It was supposed that a number of the unknown hepatitis cases was caused by the TT virus. The aim of this study was to characterize TT viruses carried by healthy individuals and patients suffering from hepatitis of unknown origin in Hungary. TTV DNA was detected by seminested PCR with the commonly used N22 primers. Twenty of the 108 sera (18.5%) taken from healthy persons and 115 of the 228 sera (50.4%) of patients with hepatitis of unknown origin were found to be positive. The nucleotide sequences of 26 clones derived from 17 hepatitis patients and 15 clones from nine healthy persons were determined and a phylogenetic tree was constructed. Genotype 2 (group 1) was found to be the most frequent, but other group 1 genotypes (1, 6) and genotypes 8 and 17 of group 2 were also detected. Mixed TTV infections were found in eight cases (two healthy persons and six hepatitis patients). Variants belonging to the same group were carried in seven cases, and the presence of group 1 (genotype 2) and group 2 (genotype 8) TTV sequences were found in one single hepatitis patient.
