Respiratory Viruses in Patients With Hematological Malignancy in Boreal Autumn/Winter 2023-2024: EPICOVIDEHA-EPIFLUEHA Report.

Community-acquired respiratory viral infections (CARV) significantly impact patients with hematological malignancies (HM), leading to high morbidity and mortality. However, large-scale, real-world data on CARV in these patients is limited. This study analyzed data from the EPICOVIDEHA-EPIFLUEHA registry, focusing on patients with HM diagnosed with CARV during the 2023-2024 autumn-winter season.

Solution equilibrium and redox properties of metal complexes with 2-formylpyridine guanylhydrazone derivatives: Effect of morpholine and piperazine substitutions.

Schiff bases derived from aminoguanidine are extensively investigated for their structural versatility. The tridentate 2-formylpyridine guanylhydrazones act as analogues of 2-formyl or 2-acetylpyridine thiosemicarbazones, where the thioamide unit is replaced by the guanidyl group. Six derivatives of 2-formylpyridine guanylhydrazone were synthesized and their proton dissociation and complex formation processes with Cu(II), Fe(II) and Fe(III) ions were studied using pH-potentiometry, UV-visible, NMR and electron paramagnetic resonance spectroscopic methods.

Tricuspid Valve S-Curves and Chamber Views: Implications for Transcatheter Tricuspid and Pulmonary Valve Interventions, Part 2 of the S-Curves and Chamber Views Series.

Despite the challenges associated with periprocedural imaging, transcatheter tricuspid valve interventions have shown important impact on outcomes. A comprehensive understanding of the anatomy of the right heart and surrounding structures is crucial. One way to optimize these interventions is by identifying the optimal fluoroscopic viewing angles along the S-curve of the tricuspid valve.

Organometallic Half-Sandwich Complexes of 8-Hydroxyquinoline-Derived Mannich Bases with Enhanced Solubility: Targeting Multidrug Resistant Cancer.

Drug resistance is a major obstacle in cancer treatment. Herein, four novel organometallic complexes, with the general formula [Ru(η--cymene)(HL)Cl]Cl and [Rh(η-CMe)(HL)Cl]Cl, were developed to target multidrug-resistant (MDR) cancer cells, where HL denotes 8-hydroxyquinoline-derived Mannich bases (HQCl-pyr and HQCl-pip). The aim of the complexation was to obtain compounds with improved drug-like properties.

Comprehensive elemental and physical characterization of vehicle brake wear emissions from two different brake pads following the Global Technical Regulation methodology.

Non-exhaust emissions have gained increasing attention during the last years, with the upcoming EURO 7 regulation defining maximum PM emission factors for tire and brake emissions for the first time. This study, therefore, focusses on broadening the knowledge on chemical composition and physical characteristics of brake dust to define emission factors for heavy metal and organic pollutants. Particles from two pads were analyzed utilizing the Worldwide Harmonised Light Vehicle Test Procedure (WLTP) brake cycle.

Selenocompounds as Potent Efflux Pump Inhibitors on Gram-positive Bacteria.

In recent years, selenocompounds have gained increasing attention as potential anticancer and antibacterial agents. Several selenoderivatives have been confirmed to act as MDR efflux pump inhibitors, based on their in vitro results against the bacterial AcrAB-TolC system and the cancer MDR efflux pump P-glycoprotein. Efflux pumps can contribute directly or indirectly to the virulence of bacteria, as they can reduce the intracellular concentration of antibacterial substances by expelling them out of the cell.

Biomarkers of Auditory-Verbal Hallucinations.

Auditory-verbal hallucinations (AVH) are debilitating symptoms experienced by those diagnosed with psychosis as well as many other neurological and psychiatric disorders. Critical to supporting individuals with AVH is identifying biomarkers that serve to track changes in brain states that put individuals at risk for developing or worsening of symptoms. There has been substantial literature identifying neural areas to track over time that may prove to be effective clinical tools.

Use and discontinuation of antipsychotic medication in 20 years following a first episode of schizophrenia: results from the OPUS trial.

Introduction: Short-term exposure to antipsychotics has proven to be beneficial. However, naturalistic studies are lacking regarding the long-term use of antipsychotics. This study aimed to investigate changes in use of antipsychotics over 20 years after a first-episode schizophrenia.

Factors influencing the uptake of antenatal care in Uganda: a mixed methods systematic review.

Background: In 2016, the World Health Organization (WHO) recommended increasing antenatal care (ANC) visits from four to eight to reduce maternal morbidity and mortality. However, many low-middle income countries (LMICs), including Uganda, struggle to achieve even the basic four ANC visits. To further improve ANC attendance, understanding the perceptions and beliefs of end users is crucial.

Novel biomarkers of mitochondrial dysfunction in Long COVID patients.

Coronavirus disease 2019 (COVID-19) can lead to severe acute respiratory syndrome, and while most individuals recover within weeks, approximately 30-40% experience persistent symptoms collectively known as Long COVID, post-COVID-19 syndrome, or post-acute sequelae of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection (PASC). These enduring symptoms, including fatigue, respiratory difficulties, body pain, short-term memory loss, concentration issues, and sleep disturbances, can persist for months. According to recent studies, SARS-CoV-2 infection causes prolonged disruptions in mitochondrial function, significantly altering cellular energy metabolism.

Outcomes of treatment cessation after switching to subcutaneous vedolizumab treatment in inflammatory bowel diseases.

Background: The usability of subcutaneous vedolizumab (s.c. VDZ) treatment in inflammatory bowel diseases (IBD; ulcerative colitis (UC), Crohn's disease (CD)) has been proven via clinical trials while real-world data collection is ongoing.

The ASAP study: association of atherosclerosis with pathobiology in a caucasian cohort-a study of 3400 autopsy reports.

Cardiovascular plaques result from atherosclerosis. Autopsy investigations of unnatural deaths provide atherosclerosis research. A Central European cohort was studied in a cross-sectional study to determine the origin of atherosclerosis and the link between arterial status and pathobiological variables.

Revising cancer incidence in a Central European country: a Hungarian nationwide study between 2011-2019 based on a health insurance fund database.

Background: The nationwide HUN-CANCER EPI study examined cancer incidence and mortality rates in Hungary from 2011 to 2019.

Methods: Using data from the National Health Insurance Fund (NHIF) and Hungarian Central Statistical Office (HCSO), our retrospective study analyzed newly diagnosed malignancies between Jan 1, 2011, and Dec 31, 2019. Age-standardized incidence and mortality rates were calculated for all and for different tumor types using both the 1976 and 2013 European Standard Populations (ESP).

Artefacts on magnetic resonance imaging with Osia®2 bone conduction hearing aid: A cadaver study.

Objectives: Hearing implants often limit the assessment of magnetic resonance examinations due to susceptibility artefacts. Our aim was to evaluate the impact of artefacts attributed to the Osia®2 implant system in terms of utility in visualizing selected cranial structures.

Methods: A BI300 implant and an OSI200 actuator were implanted into a human cadaver head in the audiologically most favourable position according to the manufacturer's guidelines.

Returned Rate and Changed Patterns of Systemic Antibiotic Use in Ambulatory Care in Hungary after the Pandemic-A Longitudinal Ecological Study.

The COVID-19 pandemic affected the epidemiology of infectious diseases and changed the operation of health care systems and health care seeking behavior. Our study aimed to analyze the utilization of systemic antibiotics in ambulatory care in Hungary after the COVID-19 pandemic and compare it to the period before COVID. We defined three periods (24 months each): Before COVID, COVID, and After COVID.
