Current Endodontic Practices among Romanian Dental Practitioners: A Cross-Sectional Study.

Root canal therapy (RCT) is usually performed in Romania by general dentists (GDPs) because they are more readily available and more reasonably priced than endodontists. Concerns have been raised about the quality of RCTs performed by GDPs, possibly due to insufficient equipment or knowledge; therefore, this study aims to investigate current endodontic practices in Romania. Materials and Methods: A cross-sectional study was conducted via a questionnaire distributed to 400 randomly selected Romanian dentists, with 285 fully validated completed responses (71.

Data for labor market concentration using Lightcast (formerly Burning Glass Technologies).

This data article provides a description of the labor market concentration dataset. Using the job vacancy data from Lightcast from 2007Q1 to 2021Q2 (2008 and 2009 data are not available), we measure labor market concentration by using Herfindahl-Hirschman Index (HHI) in labor markets defined at the occupation (six-digit SOC), commuting zone, and quarterly level. The HHI is calculated based on the share of vacancies among all the firms that post vacancies in that market.

The impact of multicentric datasets for the automated tumor delineation in primary prostate cancer using convolutional neural networks on F-PSMA-1007 PET.

Purpose: Convolutional Neural Networks (CNNs) have emerged as transformative tools in the field of radiation oncology, significantly advancing the precision of contouring practices. However, the adaptability of these algorithms across diverse scanners, institutions, and imaging protocols remains a considerable obstacle.

Regression discontinuity threshold optimization.

Treatments often come with thresholds, e.g. we are given statins if our cholesterol is above a certain threshold.

Similarity Analysis for Medical Images Using Color and Texture Histogramss.

Medical databases usually contain a significant volume of images, therefore search engines based on low-level features frequently used to retrieve similar images are necessary for a fast operation. Color, texture, and shape are the most common features used to characterize an image, however extracting the proper features for image retrievals in a similar manner with the human cognition remains a constant challenge. These algorithms work by sorting the images based on a similarity index that defines how different two or more images are, and histograms are one of the most employed methods for image comparison.

Ex vivo γH2AX assay for tumor radiosensitivity in primary prostate cancer patients and correlation with clinical parameters.

Backround: Accurate surrogate parameters for radio resistance are warranted for individualized radiotherapy (RT) concepts in prostate cancer (PCa). The purpose of this study was to assess intertumoral heterogeneity in terms of radio resistance using an ex-vivo γH2AX assay after irradiation of prostate biopsy cores and to investigate its correlation with clinical features of respective patients as well as imaging and genomic features of tumor areas.

Methods: Twenty one patients with histologically-proven PCa and pre-therapeutic multiparametric resonance imaging and prostate-specific membrane antigen positron emission tomography were included in the study.

Intraindividual Comparison Between [F] PSMA-1007 PET/CT and Multiparametric MRI for Radiotherapy Planning in Primary Prostate Cancer Patients.

Introduction: Accurate detection and segmentation of the intraprostatic gross tumor volume (GTV) is pivotal for radiotherapy (RT) in primary prostate cancer (PCa) since it influences focal therapy target volumes and the patients' cT stage. The study aimed to compare the performance of multiparametric resonance imaging (mpMRI) with [F] PSMA-1007 positron emission tomography (PET) for intraprostatic GTV detection as well as delineation and to evaluate their respective influence on RT concepts.

Materials And Methods: In total, 93 patients from two German University Hospitals with [F] PSMA-1007-PET/CT and MRI (Freiburg) or [F] PSMA-1007-PET/MRI (Dresden) were retrospectively enrolled.

The Clinical, Biological, Psychological and Psychiatric Impact of the Diagnosis of Breast Cancer in Women.

Objective: Psychosocial factors are correlated with the risk of breast cancer, by the lack of externalization of feelings and aggressive tendencies, or with a negative prognosis, by the presence of a high level of stress and reduced coping abilities. Impairment of psychological status should be assessed early to identify quantifiable psychooncological changes, such as depression, anxiety, and self-esteem. These indicators, measured in this study, may become psychometric markers for predicting the existence of the neoplastic process, prior to histopathological evaluations.

Impairment of the cardiac ejection fraction by blocking dopamine D2 receptors induced by long-acting injectable antipsychotic treatment.

Introduction: Atypical antipsychotics have numerous benefits compared to conventional ones in respect to the possible adverse effects. However, like the other ones, they may induce direct cardiovascular alterations, probably through the apoptotic effect of dopamine receptor D2 (DRD2) blockade. The main objective of the study was to assess the cardiac ejection fraction (EF) using transthoracic speckle tracking echocardiography (TSTE) in patients treated with long-acting injectable (LAI) atypical antipsychotics.

Prevalence of depression in women with low income living in developed countries.

Objective: To conduct a systematic review of studies reporting prevalence rates of depression in women living in low-income circumstances in developed countries.

Methods: The published and unpublished literature was searched for studies reporting prevalence of depression in women with low income in developed countries. Searches, data extraction, and methodological appraisal were conducted twice independently.

The impact of the Federal Pandemic Unemployment Compensation on job search and vacancy creation.

During the COVID-19 pandemic, the Federal Pandemic Unemployment Compensation (FPUC) increased US unemployment benefits by $600 a week. Theory predicts that FPUC should decrease job applications, while the effect on vacancy creation is ambiguous. We estimate the effect of FPUC on job applications and vacancy creation week by week, from March to July 2020, using granular data from the online jobs platform Glassdoor.

Depression and anxiety in recurrent giant cell tumor of bone.

Giant cell tumor of bone (GCTB) is a benign neoplasia more frequently encountered in young females. The pathogenic and evolutionary dynamics of the disease is strongly influenced by the presence of depression and cellular mechanisms, especially proinflammatory and immune. Although it is not a malignant tumor, it is often recurrent, which determines a high level of depression, anxiety, and fear of the patients.

SARS-CoV-2 infection in patients with serious mental illness and possible benefits of prophylaxis with Memantine and Amantadine.

Patients with serious mental illness are a high-risk category of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Patients with schizophrenia are not participatory and have increased mortality and morbidity, patients with dementia cannot be cared for while depression, anxiety, bipolar tubing are associated with low immune status. Social stress is amplified by social isolation, amplifying depression and the mechanisms of decreased immunity.

Incentives can reduce bias in online employer reviews.

Online reviews are widely used to propagate the reputations of employers. However, existing research suggests that online reviews often suffer from selection bias-people with extreme opinions are more motivated to select into sharing them than people with moderate opinions, resulting in more extreme ratings. We find that providing incentives for reviewing can reduce this selection bias, because incentives can mitigate the motivational deficit of people who hold moderate opinions.
