Article Synopsis
  • Hereditary angioedema due to C1 inhibitor deficiency (C1-INH-HAE) is a dangerous condition causing repeated swelling, and a study analyzed genetic defects in 207 Czech patients to understand it better.
  • Researchers used advanced techniques to identify a total of 56 genetic variants linked to the condition, including 5 new variants that likely cause the disease.
  • The findings showed a higher rate of splicing variants compared to other populations, revealed connections between certain genetic variants and disease characteristics, and emphasized the need for thorough genetic screening for better diagnosis and treatment of C1-INH-HAE.

Background: Physical activity is an effective management strategy for heart failure with reduced ejection fraction, but patients' compliance is challenging. Walking is a suitable form of physical activity due to its convenience and sustainability, and it can potentially improve functional capacity in heart failure patients.

Objectives: The WATCHFUL trial aims to determine whether a pedometer-based walking intervention combined with face-to-face sessions and regular telephone contact improves functional capacity in heart failure patients.

Department of Stomatology, General Teaching Hospital, 1st Faculty of Medicine, Charles University, 121 08, Prague, Czech Republic.

Article Synopsis
  • Dentists, identified as a high-risk group for COVID-19, showed significantly higher vaccination rates (85.8% fully vaccinated, 70.1% with a booster) compared to the general Czech population (74.9% and 49.4%, respectively).
  • Despite the high infection risk in dentistry, the study found lower COVID-19 prevalence among dentists (41.7%) than in the general population (49.9%), suggesting that enhanced protective measures were effective.
  • The findings indicated that vaccinated dentists experienced fewer complications and faster recovery, with a majority expressing willingness for future vaccinations, and showed support for mandatory vaccinations in both healthcare and the general population.

Importance: To ensure that youths can make informed decisions about their health, it is important that health recommendations be presented for understanding by youths.

Objective: To compare understanding, accessibility, usability, satisfaction, intention to implement, and preference of youths provided with a digital plain language recommendation (PLR) format vs the original standard language version (SLV) of a health recommendation.

Design, Setting, And Participants: This pragmatic, allocation-concealed, blinded, superiority randomized clinical trial included individuals from any country who were 15 to 24 years of age, had internet access, and could read and understand English.

Article Synopsis
  • The Prague-17 trial compared bleeding events in patients with atrial fibrillation (AF) treated with left atrial appendage closure (LAAC) versus nonvitamin K anticoagulants (NOAC).
  • During the study, which involved 402 high-risk AF patients over an average of 3.5 years, bleeding events were lower in the LAAC group (24 events) compared to the NOAC group (40 events).
  • The findings suggest that LAAC is associated with reduced nonprocedural major and clinically relevant nonmajor bleeding events, particularly noting gastrointestinal bleeding as the most common type in both treatment groups.

Background: Pancreatic ductal adenocarcinoma (PDAC) is associated with a very poor prognosis, with near-identical incidence and mortality. According to the World Health Organization Globocan Database, the estimated number of new cases worldwide will rise by 70% between 2020 and 2040. There are no effective screening methods available so far, even for high-risk individuals.

We present a novel approach to estimate the time-varying ascertainment rate in almost real-time, based on the surveillance of positively tested infectious and hospital admission data. We also address the age dependence of the estimate. The ascertainment rate estimation is based on the Bayes theorem.

Aims: Transcatheter aortic valve replacement (TAVR) has become the standard of care for selected patients with severe aortic stenosis. Multidetector computed tomography (MDCT) and transoesophageal 2D/3D (two-dimensional/three-dimensional) echocardiography (ECHO) are used for aortic annulus (AA) sizing. The aim of this study was to compare the accuracy of AA sizing by ECHO versus MDCT for Edwards Sapien balloon expandable valve in a single center.

Objectives: The development of fundic gland polyps (FGPs) is the most common side effect of long-term proton pump inhibitor (PPI) use; however, the effect of drug use characteristics and their impact on the risk of other gastric polyp development remain unclear. We aimed to identify the influence of PPI administration, as well as its duration and dose, in the development of gastric polyps.

Methods: A prospective cohort study was conducted on consecutive patients who underwent gastroscopy between September 2017 and August 2019.

Article Synopsis
  • - The study focuses on classic Hodgkin lymphoma (cHL), a common B-cell cancer, emphasizing that while many patients achieve remission with standard therapies, some relapse or have refractory disease, which raises concerns about long-term prognosis.
  • - Researchers conducted a retrospective analysis involving 120 patients to study the relationship between PD-L1 expression on Hodgkin-Reed-Sternberg cells and patient outcomes, with a median follow-up of 90 months.
  • - Results revealed that patients with positive PD-L1 expression had a higher relapse/refractory rate (28%) compared to those with negative expression, who did not experience any relapses, indicating that PD-L1 positivity is associated with poorer outcomes in cHL.

The clinical course of essential thrombocythemia (ET) is complicated with thrombosis which significantly impacts patients' mortality. Studies have identified JAK2V617F mutation as an independent risk factor for thrombosis. Circulating extracellular vesicles (EVs) were evaluated in several studies regarding myeloproliferative neoplasms and thrombosis as potential biomarkers.

Background: Bilateral deep brain stimulation (DBS) of the globus pallidus internus (GPi) is an effective treatment for refractory dystonia. Neuroradiological target and stimulation electrode trajectory planning with intraoperative microelectrode recordings (MER) and stimulation are used. With improving neuroradiological techniques, the need for MER is in dispute mainly because of the suspected risk of hemorrhage and the impact on clinical post DBS outcome.
