The histological grade is crucial for therapeutic management, and its reliable preoperative detection can significantly influence treatment approach. Lacking established risk factors, this study identifies preoperative predictors of high-grade skull base meningiomas and discusses the implications of non-invasive detection. A multicentric study was conducted on 552 patients with skull base meningiomas who underwent primary surgical resection between 2014 and 2019.

Weeds cause a decrease in the quantity and quality of agricultural production and economic damage to producers. The prolonged use of synthetic pesticides causes problems of environmental pollution, the possible alteration of agricultural products and problems for human health. For this reason, the scientific community's search for products of natural origin, which are biodegradable, safe for human health and can act as valid alternatives to traditional herbicides, is growing.

Background And Purpose: Diffuse gliomas, a heterogeneous group of primary brain tumors, have traditionally been stratified by histology, but recent insights into their molecular features, especially the mutation status, have fundamentally changed their classification and prognosis. Current diagnostic methods, still predominantly relying on invasive biopsy, necessitate the exploration of noninvasive imaging alternatives for glioma characterization.

Materials And Methods: In this prospective study, we investigated the utility of the spherical mean technique (SMT) in predicting the status and histologic grade of adult-type diffuse gliomas.

Introduction: Central nervous system lymphoma poses significant diagnostic challenges, with stereotactic biopsy being the gold standard for diagnosis. Intraoperative magnetic resonance imaging and intraoperative histological examination are utilized to enhance biopsy yield, yet their comparative efficacy remains unclear.

Research Question: This study aims to compare the diagnostic yield of intraoperative magnetic resonance imaging and intraoperative histological examination in stereotactic brain biopsies for central nervous system lymphoma.

Article Synopsis
  • The study examines an invasive plant species in central Europe, focusing on its potential allelopathic effects through the release of phytochemicals into the environment.* -
  • Researchers collected plant samples quarterly throughout the 2019 growing season to analyze the differences in chemical composition and potential allelopathic activity using various biological assays.* -
  • Findings indicate seasonal variations in phytochemical profiles and some phytotoxic effects on model plants, suggesting that the species' invasiveness may be linked to its chemical excretions affecting local ecosystems.*

  • The study investigated the exposure levels of polycyclic aromatic hydrocarbons (PAHs) in coke oven workers in Eastern Slovakia through cytogenetic analysis of their blood samples.
  • A total of 81 samples from exposed workers were compared to 30 control samples, revealing significant differences in chromosomal abnormalities between the two groups.
  • Despite the observed increase in chromosomal aberrations, the analysis found no significant correlation between the duration of exposure or smoking habits and the frequency of these abnormalities.

Objective: The primary objective was to comprehensively assess the association between single nucleotide polymorphisms (rs562556 and rs2479409) in the PCSK9 gene with biochemical parameters - C-reactive protein (CRP), glucose (GLU), triglyceride (TAG), low-density lipoprotein cholesterol (LDL CHOL), non-high-density lipoprotein cholesterol (non HDL CHOL), high-density lipoprotein cholesterol (HDL CHOL), cholesterol (CHOL), and anthropometric parameters (visceral fat), overweight/obesity and cardiovascular risk.

Methods: A total of 71 women aged 23-64 years were divided into three groups based on body mass index (BMI). BMI ≥ 25/≥ 30 kg/m was the criterion for assessment of overweight/obesity.

Objective: Thyroid diseases are among the most common endocrinopathies and metabolic disorders. Hypothyroidism is caused by insufficient production of thyroid hormones with a higher prevalence in women. Causes for the development of endocrine diseases may be mutations in genes that encode peptide hormones.

Objectives: Diabetes mellitus type 2 (T2DM) is a multifactorial and polygenic disorder characterised by chronic hyperglycaemia accompanied by impaired lipid, carbohydrate, and protein metabolism. The disease is associated with several genetic polymorphisms, including the FokI polymorphism in the vitamin D receptor (VDR) gene.

Methods: We conducted a study of 327 probands (191 T2DM patients, 136 controls), with a mean age 65.

Objectives: Physiological ageing is associated with major and progressive changes in body composition, particularly in the decline of fat-free mass, which puts older individuals at risk of geriatric syndromes such as sarcopenia and sarcopenic obesity. Bioimpedance analysis noninvasively allows the determination of body composition, thus being able to rapidly assess primary risk factors leading to sarcopenia prediction.

Methods: We conducted a study of 180 probands, 120 females (66.

Article Synopsis
  • This study examined foot arch shapes and health in adults from eastern Slovakia, aiming to identify factors that affect foot arch abnormalities.
  • The research utilized standard measurements and questionnaires, finding a significant link between wearing shoes at home and right foot arch support, as well as a connection between high heels and foot arch disorders.
  • Most participants had normal arches, suggesting that while many orthopaedic devices are available, they should be used only with professional guidance to avoid improper use.

Background: Inhaled corticosteroids have been widely reported as a preventive measure against the development of severe forms of COVID-19 not only in patients with asthma.

Methods: In 654 Czech and Slovak patients with asthma who developed COVID-19, we investigated whether the correct use of inhaler containing corticosteroids was associated with a less severe course of COVID-19 and whether this had an impact on the need for hospitalisation, measurable lung functions and quality of life (QoL).

Results: Of the studied cohort 51.

Background: Tumor consistency is considered to be a critical factor for the surgical removal of meningiomas and its preoperative assessment is intensively studied. A significant drawback in the research of predictive methods is the lack of a clear shared definition of tumor consistency, with most authors resorting to subjective binary classification labeling the samples as "soft" and "hard." This classification is highly observer-dependent and its discrete nature fails to capture the fine nuances in tumor consistency.

The accurate identification and preservation of the facial nerve (FN) during vestibular schwannoma (VS) surgery is crucial for maintaining facial function. Investigating the application of diffusion tensor imaging (DTI) in preoperative planning for large VS surgery is provided. PubMed, Cochrane Library, Science Direct, ISI Web of Science, Embase, and additional sources were searched to identify cohort studies about the preoperative DTI usage for the FN tracking before large VS (≥ 2.

The aim of this study was to investigate whether white matter changes as measured by diffusion tensor imaging (DTI) can help differentiate shunt-responsive idiopathic normal pressure hydrocephalus (iNPH) patients from patients with other causes of gait disturbances and/or cognitive decline with ventriculomegaly whose clinical symptoms do not improve significantly after cerebrospinal fluid derivation (non-iNPH). Between 2017 and 2022, 85 patients with probable iNPH underwent prospective preoperative magnetic resonance imaging (MRI) and comprehensive clinical workup. Patients with clinical symptoms of iNPH, positive result on lumbar infusion test, and gait improvement after 120-h lumbar drainage were diagnosed with iNPH and underwent shunt-placement surgery.
