RESUMEN
OBJECTIVE: To assess the potential long-term cardiac effects after multisystem inflammatory syndrome in children (MIS-C) with cardiovascular involvement in the acute phase. STUDY DESIGN: Our prospective study involved children consecutively diagnosed with MIS-C between October 2020 and February 2022 and followed 6 weeks and 6 months after the disease. In patients with severe cardiac involvement during the acute phase, an additional check-up after 3 months was scheduled. In all patients at all check-ups, 3-dimensional echocardiography and global longitudinal strain (GLS) were used to assess ventricular function. RESULTS: The study enrolled 172 children aged 1-17 years (median, 8 years). The means of ejection fraction (EF) and GLS for both ventricles were within normal limits after 6 weeks with no relationship with initial severity: left ventricular EF (LVEF) 60% (59%-63%), LV GLS -21.08% (-18.63% to -23.2%), right ventricular (RV) EF 64% (62%-67%), and RV GLS -22.8% (-20.5% to -24.5%). Further, statistically significant improvement of LV function was observed after 6 months-LVEF 63% (62%-65%) and LV GLS -22.55% (-21.05% to -24.25%; P < .05); however, RV function remained unchanged. The group with severe cardiac involvement showed LV function recovery pattern with no significant improvement between 6 weeks and 3 months after MIS-C, while still improving between 3 and 6 months after discharge. CONCLUSIONS: LV and RV function is within normal limits 6 weeks after MIS-C regardless of severity of cardiovascular involvement; LV function improves further between 6 weeks and 6 months after the disease. The long-term prognosis is optimistic with full recovery of cardiac function.

INTRODUCTION: Electronic health records (EHRs) contain data valuable for clinical research. However, they are in textual format and require manual encoding to databases, which is a lengthy and costly process. Natural language processing (NLP) is a computational technique that allows for text analysis. OBJECTIVES: Our study aimed to demonstrate a practical use case of NLP for a large retrospective study cohort characterization and comparison with human retrieval. PATIENTS AND METHODS: Anonymized discharge documentation of 10 314 patients from a cardiology tertiary care department was analyzed for inclusion in the CRAFT registry (Multicenter Experience in Atrial Fibrillation Patients Treated with Oral Anticoagulants; NCT02987062). Extensive clinical characteristics regarding concomitant diseases, medications, daily drug dosages, and echocardiography were collected manually and through NLP. RESULTS: There were 3030 and 3029 patients identified by human and NLPbased approaches, respectively, reflecting 99.93% accuracy of NLP in detecting AF. Comprehensive baseline patient characteristics by NLP was faster than human analysis (3 h and 15 min vs 71 h and 12 min). The calculated CHA2DS2VASc and HASBLED scores based on both methods did not differ (human vs NLP; median [interquartile range], 3 [2-5] vs 3 [2-5]; P = 0.74 and 1 [1-2] vs 1 [1-2]; P = 0.63, respectively). For most data, an almost perfect agreement between NLP- and human-retrieved characteristics was found; daily dosage identification was the least accurate NLP feature. Similar conclusions on cohort characteristics would be made; however, daily dosage detection for some drug groups would require additional human validation in the NLPbased cohort. CONCLUSIONS: NLP utilization in EHRs may accelerate data acquisition and provide accurate information for retrospective studies.

Shiga toxin-producing Escherichia coli (STEC) are zoonotic pathogens causing hemorrhagic colitis and hemolytic uremic syndrome (HUS) in children and the elderly. Stool samples were collected from 180 children hospitalized in five pediatric centers in Poland in 2018-2022. Direct stx1/stx2 gene detection by PCR in feces and E. coli isolates was performed. Antibiotic susceptibility was tested according to EUCAST v.12. Randomly selected isolates were serotyped with O157 antiserum and genotyped by pulsed-field gel electrophoresis (PFGE). A total of 44 E. coli isolates were confirmed as STEC by PCR. Among them, 84.4% were positive for stx2, and equally 6,8% for only stx1 and both stx1 and stx2 genes. The stx1 gene was also found in one Citrobacter freundii isolate. E. coli serotype O157 was present in 97.6% of the isolates. STEC infections most often occurred between June-October with a peak in July and August (51%). The highest, 77.8% of STEC isolates were found in the 1-5 years old group. No extended-spectrum ß-lactamases (ESBL) were found. Resistance only to amoxicillin/clavulanic acid (24.4%), piperacillin/tazobactam (3%), cefotaxime (6%), gentamicin (6%), ciprofloxacin (3%), azithromycin (3%), trimethoprim/sulfamethoxazole (24,2%) was detected. PFGE analysis showed 18 PFGE types with no clonal distribution. Eight isolates with A, B, and C PFGE types showed genetic relatedness in the type with no detection of transmission way of distribution. STEC strains pose a serious threat to human health, therefore demographic and epidemiological characteristics are crucial for their surveillance.

INTRODUCTION: Electronic health records (EHR) are of great value for clinical research. However, EHR consists primarily of unstructured text which must be analysed by a human and coded into a database before data analysis- a time-consuming and costly process limiting research efficiency. Natural language processing (NLP) can facilitate data retrieval from unstructured text. During AssistMED project, we developed a practical, NLP tool that automatically provides comprehensive clinical characteristics of patients from EHR, that is tailored to clinical researchers needs. MATERIAL AND METHODS: AssistMED retrieves patient characteristics regarding clinical conditions, medications with dosage, and echocardiographic parameters with clinically oriented data structure and provides researcher-friendly database output. We validate the algorithm performance against manual data retrieval and provide critical quantitative and qualitative analysis. RESULTS: AssistMED analysed the presence of 56 clinical conditions, medications from 16 drug groups with dosage and 15 numeric echocardiographic parameters in a sample of 400 patients hospitalized in the cardiology unit. No statistically significant differences between algorithm and human retrieval were noted. Qualitative analysis revealed that disagreements with manual annotation were primarily accounted to random algorithm errors, erroneous human annotation and lack of advanced context awareness of our tool. CONCLUSIONS: Current NLP approaches are feasible to acquire accurate and detailed patient characteristics tailored to clinical researchers' needs from EHR. We present an in-depth description of an algorithm development and validation process, discuss obstacles and pinpoint potential solutions, including opportunities arising with recent advancements in the field of NLP, such as large language models.

Extracellular Neutrophils Traps (NETs) and their formation, known as NETosis, have become pivotal in the pathogenesis of aortic aneurysm development. This study investigates the NETosis markers with the assessment of selected parameters of inflammation and coagulation system in patients with thoracoabdominal aortic aneurysms in the pre-and postop period undergoing t-Branch stent-graft implantation. The study included 20 patients with thoracoabdominal aortic aneurysms. Three markers double-stranded DNA (dsDNA), single-stranded DNA (ssDNA), and citrullinated H3 histones (Cit-H3) were tested at three-time points from patients' blood. The parameters of NETosis, inflammation, and coagulation system were examined in the preoperative period (within 24â h before surgery) and in the postoperative period (on the 3rd and 5th postoperative day). Free-circulating DNA (cfDNA) was isolated from the blood using the MagMAXTM Cell-Free DNA Extraction Kit. Double-stranded DNA (dsDNA) and single-stranded DNA (ssDNA) were then quantified using the Qubit dsDNA HS Assay Kit and the Qubit ssDNA Assay Kit. Cit-H3 concentration was determined by enzyme immunoassay ELISA (Cayman). The results revealed the significance of NETs secretion in response to the complex processes after stent-graft implantation. All NET markers increased shortly after surgery, with histones being the first to return to preoperative levels. The lack of normalization of dsDNA and ssDNA levels to preoperative levels by the last postoperative blood collection demonstrates NETs reorganization. The increase in the number of neutrophils was not related to the expansion of postoperative NETosis. The study reveals a new marker of NETosis, ssDNA, that has not been studied so far. The implantation of a stent graft in a patient with TAAA triggers an inflammatory response manifested by an increase in inflammatory parameters. One of the hallmarks of inflammation is the activation of neutrophil extracellular traps.
RESUMEN
BACKGROUND: Impella is a percutaneous mechanical circulatory support device for treatment of cardiogenic shock (CS) and high-risk percutaneous coronary interventions (HR-PCIs). IMPELLA-PL is a national retrospective registry of Impella-treated CS and HR-PCI patients in 20 Polish interventional cardiological centers, conducted from January 2014 until December 2021. AIMS: We aimed to determine the efficacy and safety of Impella using real-world data from IMPELLA-PL and compare these with other registries. METHODS: IMPELLA-PL data were analyzed to determine primary endpoints: in-hospital mortality and rates of mortality and major adverse cardiovascular and cerebrovascular events (MACCE) at 12 months post-discharge. RESULTS: Of 308 patients, 18% had CS and 82% underwent HR-PCI. In-hospital mortality rates were 76.4% and 8.3% in the CS and HR-PCI groups, respectively. The 12-month mortality rates were 80.0% and 18.2%, and post-discharge MACCE rates were 9.1% and 22.5%, respectively. Any access site bleeding occurred in 30.9% of CS patients and 14.6% of HR-PCI patients, limb ischemia in 12.7% and 2.4%, and hemolysis in 10.9% and 1.6%, respectively. CONCLUSIONS: Impella is safe and effective during HR-PCIs, in accordance with previous registry analyses. The risk profile and mortality in CS patients were higher than in other registries, and the potential benefits of Impella in CS require investigation.

(1) Background: Administrative data allows for time- and cost-efficient acquisition of large volumes of individual patient data invaluable for evaluation of the prevalence of diseases and clinical outcomes. The aim of the study was to evaluate the accuracy of data collected from the Polish National Health Fund (NHF), from a researcher's perspective, in regard to a cohort of atrial fibrillation patients. (2) Methods: NHF data regarding atrial fibrillation and common cardiovascular comorbidities was compared with the data collected manually from the individual patients' health records (IHR) collected in the retrospective CRAFT registry (NCT02987062). (3) Results: Data from the NHF underestimated the proportion of patients with AF (NHF = 83% vs. IHR = 100%) while overestimating the proportion of patients with other cardiovascular comorbidities in the cohort. Significantly higher CHA2DS2VASc (Median, [Q1-Q3]) (NHF: 1, [0-2]; vs. IHR: 1, [0-1]; p < 0.001) and HAS-BLED (Median, [Q1-Q3]) (NHF: 4, [2-6] vs. IHR: 3, [2-5]; p < 0.001) scores were calculated according to NHF in comparison to IHR data, respectively. (4) Conclusions: Clinical researchers should be aware that significant differences between IHR and billing data in cardiovascular research can be observed which should be acknowledged while drawing conclusions from administrative data-based cohorts. Natural Language Processing of IHR could further increase administrative data quality in the future.

BACKGROUND: Among patients with an implanted cardiac implantable electronic device (CIED), ipsilateral upper extremity vein stenosis or occlusion (VSO) is observed more frequently than in the general population. However, there are no data available concerning the relationship between hemostatic markers (and their dynamics) and the occurrence of VSO. The aim of this study was to assess the predictive value of beta-thromboglobulin, the von Willebrand factor (vWF), fibrynogen and D-dimer for VSO development among first time CIED recipients. METHODS: This is a single-center, prospective study of consecutive first time CIED recipients without upper extremity VSO in baseline ultrasound examination. Biochemical data were collected from all the patients before CIED implantation (first measuring), up to 7 days subsequent (second measuring) and 6 months after the operation (third measuring). Primary endpoint was defined as the presence of upper extremity VSO at the implantation site during the ultrasound examination 6 months after the operation. RESULTS: The study included 71 patients (mean age 73.1 ± 10.5 years; 39 [55%] male). The incidence of VSO within 6-months follow up was 21.1%. Average concentrations of hemostatic markers increased significantly in all patients immediately after CIED implantation. Serial hemostatic marker concentrations were similar in patients who met or did not meet the primary endpoint, apart from vWF. The mean concentration was significantly elevated in the group of 15 patients who reached the primary endpoint (p = 0.032). CONCLUSIONS: A significant increase in vWF concentration at 6 months post implantation may be a marker for VSO occurrence.

BACKGROUND: The most frequent cause of sudden cardiac arrest (SCA) is ventricular fibrillation and ventricular tachycardia. Despite many efforts the prognosis in this patient group is poor. According to the European Resuscitation Council (ERC) recommendations, early defibrillation, preferably in the first 3-5 min, is a key link in the Chain of Survival after SCA. With an increasing number of available automated external defibrillators (AED) time from SCA to defibrillation may be reduced, thus resulting in the improvement of patients' prognosis. Therefore, the ERC recommends providing AED in public locations with a high incidence of cardiac arrests. AIM: Estimation of the availability of AED in the city of Warsaw. METHODS: Automated external defibrillators were identified according to the information from the City Hall, public services, foundations, companies and own research and knowledge. The AED presence was confirmed by phone at the potential locations and random locations were visited. RESULTS: By 15 May 2009, 117 AED had been reported in 83 points in the city of Warsaw. The number of AED was the highest in the Sródmiescie (29) and Wlochy (28) districts. On average, there was one AED per 14 706 citizens (0.68 per 10,000 citizens) and per 4.24 km(2) (2.26 per 10 km(2)). The highest ratio of the number of AED per 10,000 citizens was observed in the Wlochy (7.06) and Sródmiescie (2.25) districts, the lowest - in the Targówek (0.16), Wawer (0.15) and Bemowo (0.09) districts. The highest ratio of the number of AED per 10 km(2) were in the Sródmiescie (18.63), Wlochy (9.78) and Zoliborz (5.9) districts, the lowest - in the Wilanów (0.27) and Wawer (0.13) districts. CONCLUSIONS: The number of AED in the city of Warsaw should be increased, additional demonstrations of AED proper usage and AED promotion should be organised. It is necessary to provide easy access to the devices. Significant differences in the number of AED can be observed between the districts. Neither authorities nor public services are aware of the number of AED in the city of Warsaw.

The aim of this work is to present whether SPECT 99mTc-HMPAO can be a method of examination to possibly differentiate the syndromes. 21 patients with PSP syndrome and 14 patients with corticobasal syndrome (CBS) were examined using SPECT 99mTc-HMPAO. Perfusion single photon emission computed tomography (SPECT) as a method of examination of progressive supranuclear palsy (PSP) and corticobasal syndrome (CBS) has not been extensively analyzed in contemporary literature. Recent criteria of PSP and CBS do not describe this method of examination as primary or additional. Extended analysis was done in the context of regions of interest affected by significant average hypoperfusion (>2 standard deviations). Differences between the syndromes were subsequently evaluated using the U-Mann-Whitney test. Lack of significant differences (p < 0.05) were observed in 92 out of 94 regions of interest. However, certain asymmetries were observed in a minority of regions in both of the syndromes. Additionally, the authors of the study verified possible differences of asymmetry of perfusion of both of the syndromes. The overlapping of clinical manifestations and locations of hypoperfusion leads to a question of whether the syndromes should be interpreted as separate entities or variants of the same disease.

BACKGROUND: In the midst of the SARSCoV2 pandemic, basic healthcare challenges arise as lockdowns and social isolation are implemented to prevent the spread of the virus. In order to overcome these challenges, the Polish National Health Fund has facilitated telemedical consultations. AIMS: The aim of this study was to compare teleconsultations with regular visits at ambulatory clinic of implantable devices and to assess whether teleconsultations would be an adequate replacement during times of limited facetoface contact. METHODS: Teleconsultations in the clinic were introduced for patients without the possibility of remote control of cardiac implantable electronic devices. Prior to planned visits, physicians phoned patients and interviewed them about their health. Further treatment decisions were made based on the interview and available medical records. RESULTS: Teleconsultations were carried out over 3.5 weeks (March 13 to April 1, 2020). Out of 400 patients who had visits planned at the clinic, 349 were consulted by phone. A total of 299 patients confirmed stable health status, 14 reported some symptoms, and 4 were hospitalized; 2 patients changed their primary clinic and were no longer under our care, 1 was undergoing quarantine, 15 required additional intervention, and 15 had died prior to contact. In general, patients gave positive feedback on their teleconsultations. CONCLUSIONS: Teleconsultations are a muchneeded option during the SARSCoV2 pandemic. They are an effective way to decrease interpersonal contact and to overcome sudden changes to the ambulatory visit plan, which may otherwise put an overwhelming burden on the clinic.

BACKGROUND: The Micra transcatheter pacing system (TPS) is a miniaturized, single-chamber pacemaker system. Study reported herein is an initial experience with implantation of the Micra TPS. METHODS: The leadless pacemaker was implanted in 10 patients with standard indications for a permanent pacemaker implantation. All hospitalization costs were calculated for all patients. RESULTS: The mean age of the patients was 75 ± 7.1 years, 6 were men and 4 were women. Four patients had permanent atrial fibrillation as the basal rhythm and 6 patients had sinus rhythm. All patients had at least one relative contraindication that precluded the use of a traditional pacing system. Mean intraoperative ventricular sensing amplitude was 10.6 ± 5.4 mV, impedance 843 ± 185 ohms, and pacing threshold at 0.24 ms was 0.56 ± 0.23 V. At discharge, those values were 13.9 ± 5.6 mV, 667 ± 119 ohms and 0.47 ± 0.17, respectively. The mean duration of implantation procedure was 82 min, while mean fluoroscopy time was 3.5 min. Two patients developed hematoma at the groin puncture site post-implantation. In 1 case there was a need for erythrocyte mass transfusion and surgical intervention. Mean total time of hospitalization was 26 days and time from procedure to discharge 12 days. Average cost of hospitalization per 1 patient was 11,260.15 EUR minimal cost was 9,052.68 EUR, while maximal cost was 16,533.18 EUR. CONCLUSIONS: Implantation of leadless pacemakers is feasible, safe and provides advantages over the conventional system. Hospitalization costs vary for individual patients in wide range.

BACKGROUND: Remote monitoring of cardiovascular implantable electronic devices allows the assessment of system effectiveness, arrhythmia occurrence, and indirectly, clinical changes. Medical interventions can be performed earlier because of a faster transfer of information to the monitoring site, even in the case of asymptomatic arrhythmias or abnormalities in the operation of the system. AIMS: The aim of the study was to assess the effectiveness of remote monitoring of implantable cardioverter-defibrillators and evaluation in an outpatient setting during 12-month follow -up. METHODS: We analyzed 176 patients at 10 sites (men, 84.1%). The mean (SD) age of the patients was 60.7 (12.5) years (range, 20-86 years), and mean (SD) follow -up period was 405 (70) days (range, 131-723 days). RESULTS: A total of 354 outpatient and 514 remote follow -up visits were conducted. Episodes of arrhythmias and device malfunctions were detected with similar frequency in outpatient visits and in remote visits. During the study period, patient sense of safety increased. More patients preferred joined remote and outpatient visits as the optimal healthcare model. As the patient survey showed, the greatest benefit of the CareLink network was fast intervention and an increased sense of safety. CONCLUSIONS: The strategy of remote monitoring appeared to be feasible, safe, and patient friendly, demonstrating that the majority of patients do not require an additional in -person visit within 1 year from the device implantation just to confirm the proper functioning of the implantable cardioverter--defibrillators.

BACKGROUND: The impact of cardiac rehabilitation on the number of alerts in patients with remote monitoring (RM) of cardiac implantable electronic devices (CIEDs) is unknown. We compared alerts in RM and outcomes in patients with CIEDs undergoing hybrid comprehensive telerehabilitation (HCTR) versus usual care (UC). METHODS: Patients with heart failure (HF) after a hospitalization due to worsening HF within the last 6 months (New York Heart Association (NYHA) class I-III and left ventricular ejection fraction (LVEF) ≤40%) were enrolled in the TELEREH-HF study and randomised 1:1 to HCTR or UC. Patients with HCTR and CIEDs received RM (HCTR-RM). Patients with UC and CIEDs were offered RM optionally (UC-RM). Data from the initial 9 weeks of the study were analysed. RESULTS: Of 850 enrolled patients, 208 were in the HCTR-RM group and 62 in the UC-RM group. The HCTR-RM group was less likely to have alerts of intrathoracic impedance (TI) decrease (p < 0.001), atrial fibrillation (AF) occurrence (p = 0.031) and lower mean number of alerts per patient associated with TI decrease (p < 0.0001) and AF (p = 0.019) than the UC-RM group. HCTR significantly decreased the occurrence of alerts in RM of CIEDs, 0.360 (95%CI, 0.189-0.686; p = 0.002), in multivariable regression analysis. There were two deaths in the HCTR-RM group (0.96%) and no deaths in the UC-RM group (p = 1.0). There were no differences in the number of hospitalised patients between the HCTR-RM and UC-RM group (p = 1.0). CONCLUSIONS: HCTR significantly reduced the number of patients with RM alerts of CIEDs related to TI decrease and AF occurrence. There were no differences in mortality or hospitalisation rates between HCTR-RM and UC-RM groups.
RESUMEN
Importance: Guidelines recommend exercise training as a component of heart failure management. There are large disparities in access to rehabilitation, and introducing hybrid comprehensive telerehabilitation (HCTR) consisting of remote monitoring of training at patients' homes might be an appealing alternative. Objective: To assess whether potential improvements in quality-of-life outcomes after a 9-week HCTR intervention in patients with heart failure translate into improvement in clinical outcomes during extended 12 to 24 months of follow-up, compared with usual care. Design, Setting, and Participants: The Telerehabilitation in Heart Failure Patients (TELEREH-HF) trial is a multicenter, prospective, open-label, parallel-group randomized clinical trial that enrolled 850 patients with heart failure up to 6 months after a cardiovascular hospitalization with New York Heart Association levels I, II, or III and left ventricular ejection fraction of 40% or less. Patients from 5 centers in Poland were randomized 1:1 to HCTR plus usual care or usual care only and followed up for 14 to 26 months after randomization. Interventions: During the first 9 weeks, patients underwent either an HCTR program (1 week in hospital and 8 weeks at home) or usual care with observation. The HCTR intervention encompassed telecare, telerehabilitation, and remote monitoring of implantable devices. No intervention occurred in the remaining study period. Main Outcomes and Measures: The percentage of days alive and out of the hospital from randomization through the end of follow-up at 14 to 26 months. Results: A total of 850 patients were enrolled, with 425 randomized to the HCTR group (377 male patients [88.7%]; mean [SD] age, 62.6 [10.8] years) and 425 randomized to usual care (376 male patients [88.5%]; mean [SD] age, 62.2 [10.2] years). The HCTR intervention did not extend the percentage of days alive and out of the hospital. The mean (SD) days were 91.9 (19.3) days in the HCTR group vs 92.8 (18.3) days in the usual-care group, with the probability that HCTR extends days alive and out of the hospital equal to 0.49 (95% CI, 0.46-0.53; P = .74) vs usual care. During follow-up, 54 patients died in the HCTR arm and 52 in the usual-care arm, with mortality rates at 26 months of 12.5% vs 12.4%, respectively (hazard ratio, 1.03 [95% CI, 0.70-1.51]). There were also no differences in hospitalization rates (hazard ratio, 0.94 [95% CI, 0.79-1.13]). The HCTR intervention was effective at 9 weeks, significantly improving peak oxygen consumption (0.95 [95% CI, 0.65-1.26] mL/kg/min vs 0.00 [95% CI, -0.31 to 0.30] mL/kg/min; P < .001) and quality of life (Medical Outcome Survey Short Form-36 questionnaire score, 1.58 [95% CI, 0.74-2.42] vs 0.00 [95% CI, -0.84 to 0.84]; P = .008), and it was well tolerated, with no serious adverse events during exercise. Conclusions and Relevance: In this trial, the positive effects of a 9-week program of HCTR in patients with heart failure did not lead to the increase in percentage of days alive and out of the hospital and did not reduce mortality and hospitalization over a follow-up period of 14 to 26 months. Trial Registration: ClinicalTrials.gov identifier: NCT02523560.

INTRODUCTION: Venous stenosis or occlusion related to an intracardiac device is a well-known complication of that procedure. There are numerous studies tried to determine predictors of venous stenosis or occlusion; however, most of them investigate the venous system prior to device upgrade, generator replacement, or transvenous lead extraction. Therefore, we aimed to assess the prevalence and determine the predictors of venous stenosis or occlusion following first transevnous cardiac device implantation. METHODS: Observational, prospective study included 71 consecutive patients admitted for first transvenous cardiac device implantation. All patients were followed up for 6 months after operation. RESULTS: Implanted device systems comprised cardioverter defibrillator (n = 26), single-chamber or dual-chamber pacemakers (n = 34), and biventricular pacemakers (n = 11); 88.5% of implantable cardioverter defibrillator leads were single-coils and 11.5% were dual-coils. The incidence of venous stenosis or occlusion within 6-month follow-up was 21.1%. Multivariate logistic regression showed that only diabetes or prediabetes (p = 0.033, odds ratio: 0.17, 95% confidence interval: 0.04-0.87), prolonged procedure time (p = 0.046, odds ratio: 4.54, 95% confidence interval: 1.01-20.12), and perioperative complications (p = 0.021, odds ratio: 7.04, 95% confidence interval: 1.35-36.85) were predictors of venous stenosis or occlusion. CONCLUSION: Prolonged implantation time (>60 min) and perioperative complications are associated with an increased risk of venous stenosis or occlusion, whereas diabetes and prediabetes significantly reduce the risk of venous stenosis or occlusion.

Neuroimaging in the context of examining atypical parkinsonian tauopathies is an evolving matter. Positron emission tomography and single photon emission computed tomography (SPECT) bring tools, which may be reasonable in supplementary examination, however, cannot be interpreted as a criterion standard for correct diagnosis. The aim of this observational study was to assess the differentiating potential of perfusion SPECT in 3 types of atypical parkinsonisms: multiple system atrophy parkinsonian type (MSA-P), corticobasal syndrome (CBS), and progressive supranuclear palsy (PSP). The study was carried out using the comparison of standard deviations of perfusion in patients from these 3 groups. Data obtained from 10 patients with clinical diagnosis MSA-P, 14 patients with CBS and 21 patients with PSP, which were analyzed using Tukey honest significant difference post-hoc test, revealed significant differences of perfusion Pâ<â.05 between MSA-P and PSP within the cerebellum and thalamus. No significant differences between CBS and PSP were observed.
