The impact of rhythm perception on chest compression rate during CPR: Insights from a pilot simulation study.

Objective: This pilot study aims to assess how individuals with rhythm perception, particularly musicians, are able to maintain the predefined chest compression rate during cardiopulmonary resuscitation compared to people without rhythm perception.

Methods: The study was conducted at the Pilsen Emergency Medicine Conference (Czechia) using a simulation-based cohort design. Participants performed chest compressions on a manikin for 120 s, with the first 10 s guided by a metronome.

Calorimetry probe for runaway electron heat load measurement at COMPASS.

Runaway electrons, accelerated in a tokamak discharge to high energies (tens of MeV), can cause serious damage to plasma facing components. Therefore, it is important to develop effective mitigation strategies to reduce the risk of tokamak damage. To study the effects of various mitigation strategies, a dedicated diagnostic, the calorimetry probe, was developed at the COMPASS tokamak.

Photoregulatory functions drive variation in eye coloration across macaque species.

Primates, the most colorful mammalian radiation, have previously served as an interesting model to test the functions and evolutionary drivers of variation in eye color. We assess the contribution of photo-regulatory and communicative functions to the external eye appearance of nine macaque species representing all the branches of their radiation. Macaques' well described social structure and wide geographical distribution make them interesting to explore.

The topic of not initiating resuscitation from the perspective of Czech law not only in the context of palliative care.

In the age of advanced modern medicine, prolonging the lives of patients is becoming easier and easier. Science is even going so far that some authors are beginning to see the need to advocate for the patient's right to die. The authors of the recommended resuscitation procedures themselves state that prolonging the inevitable dying process should be considered a harm (dysthanasia).

Blood pressure behavior during exercise in patients with diastolic dysfunction and a hypertensive response to exercise.

A hypertensive response to exercise is a precursor leading to hypertension, which is a major risk factor for the development of heart failure and diastolic dysfunction. Herein, we aimed to assess blood pressure (BP) in patients with a hypertensive response to exercise and different degrees of diastolic dysfunction. Between January 2009 and December 2014, 373 patients with a hypertensive response to exercise (HRE) and echocardiographic data assessing diastolic function were enrolled at the University Hospital of Zurich.

Blood pressure response during exercise testing in individuals with and without hypertension: The value of the recovery phase.

Background: Hypertension and exercise testing are essential for cardiovascular risk assessment. However, an exact description of blood pressure (BP) in patients with a hypertensive response during exercise (HRE), especially in the recovery phase is lacking. Herein, we aimed to analyse BP and heart rate during exercise testing and recovery in patients with an HRE.

Peripheral Retinal Haemorrhages in a Patient with MOG-Associated Optic Neuritis.

A 15-year-old female presented with headaches and bilateral vision loss. Fundoscopic examination revealed bilateral optic nerve oedema as well as peripheral retinal haemorrhages. Magnetic resonance imaging of the brain showed findings consistent with bilateral optic neuritis.

KdpD is a tandem serine histidine kinase that controls K pump KdpFABC transcriptionally and post-translationally.

Two-component systems, consisting of a histidine kinase and a response regulator, serve signal transduction in bacteria, often regulating transcription in response to environmental stimuli. Here, we identify a tandem serine histidine kinase function for KdpD, previously described as a histidine kinase of the KdpDE two-component system, which controls production of the potassium pump KdpFABC. We show that KdpD additionally mediates an inhibitory serine phosphorylation of KdpFABC at high potassium levels, using not its C-terminal histidine kinase domain but an N-terminal atypical serine kinase domain.

From molecular signatures to radiomics: tailoring neurooncological strategies through forecasting of glioma growth.

Objective: Contemporary oncological paradigms for adjuvant treatment of low- and intermediate-grade gliomas are often guided by a limited array of parameters, overlooking the dynamic nature of the disease. The authors' aim was to develop a comprehensive multivariate glioma growth model based on multicentric data, to facilitate more individualized therapeutic strategies.

Methods: Random slope models with subject-specific random intercepts were fitted to a retrospective cohort of grade II and III gliomas from the database at Kepler University Hospital (n = 191) to predict future mean tumor diameters.

Tailored Intraoperative MRI Strategies in High-Grade Glioma Surgery: A Machine Learning-Based Radiomics Model Highlights Selective Benefits.

Background And Objectives: In high-grade glioma (HGG) surgery, intraoperative MRI (iMRI) has traditionally been the gold standard for maximizing tumor resection and improving patient outcomes. However, recent Level 1 evidence juxtaposes the efficacy of iMRI and 5-aminolevulinic acid (5-ALA), questioning the continued justification of iMRI because of its associated costs and extended surgical duration. Nonetheless, drawing from our clinical observations, we postulated that a subset of intricate HGGs may continue to benefit from the adjunctive application of iMRI.

Correlation Between Visual Acuity and Foveal Threshold by Automated Perimetry With Size V Stimulus.

Background: Visual acuity has been shown to correlate with foveal threshold as determined by automated perimetry. Although automated perimetry with size V stimulus is commonly used in neuro-ophthalmology practice, the relationship between the visual acuity and the foveal threshold with this larger stimulus is not well known.

Methods: Retrospective study of patients who had undergone neuro-ophthalmology evaluation and visual field testing with automated perimetry using size V stimulus.

2023 EULAR recommendations for the management of fatigue in people with inflammatory rheumatic and musculoskeletal diseases.

Objectives: Fatigue is prevalent in people with inflammatory rheumatic and musculoskeletal diseases (I-RMDs) and recognised as one of the most challenging symptoms to manage. The existence of multiple factors associated with driving and maintaining fatigue, and the evidence about what improves fatigue has led to a multifaceted approach to its management. However, there are no recommendations for fatigue management in people with I-RMDs.

COVID-19 cross-border case and contact tracing activities - experiences and lessons learnt, Germany, April-December 2020.

Background: Interruption of transmission chains has been crucial in the COVID-19 response. The Emergency Operations Centre (EOC) at the Robert Koch Institute (RKI) coordinated cross-border case and contact tracing activities at the national level by sharing data with German public health authorities (PHA) and other countries. Data on these activities were not collected in the national surveillance system, and thus were challenging to quantify.

Deep-sea benthic crustacean and annelid data from the Bering Sea.

Samples of Crustacea and Annelida (Polychaeta, Sipuncula, and Hirudinea) were collected in the Bering Sea and the northwestern Pacific Ocean during scientific cruise SO-249 BERING in 2016. Biological samples were collected from 32 locations by the team on-board RV Sonne using a chain bag dredge at depths ranging between 330-5,070 m, and preserved in 96% ethanol. Specimens were morphologically identified to the lowest taxonomic level possible using a Leica M60 stereomicroscope.

Deep learning-assisted radiomics facilitates multimodal prognostication for personalized treatment strategies in low-grade glioma.

Determining the optimal course of treatment for low grade glioma (LGG) patients is challenging and frequently reliant on subjective judgment and limited scientific evidence. Our objective was to develop a comprehensive deep learning assisted radiomics model for assessing not only overall survival in LGG, but also the likelihood of future malignancy and glioma growth velocity. Thus, we retrospectively included 349 LGG patients to develop a prediction model using clinical, anatomical, and preoperative MRI data.
