Hepatitis B Prevalence and Referral Rates in Vulnerable Populations Undergoing Community-Based Screening-Results from the LIVE(RO)2 Program.

Hepatitis B Virus (HBV) remains a major global health challenge, with significant morbidity and mortality associated with chronic infections. This study examines the epidemiology, screening, and risk factors associated with HBV in Romania, focusing on a comprehensive national screening program, LIVE(RO)2, involving 320,000 individuals (majority of them considered vulnerable population). A questionnaire was used to collect information on the potential risk factors for HBV transmission.

Morphometric study for determining the anteroposterior position of the mental foramen in dentate human subjects.

Background: The mental foramen (MnF) is the place where the mental nerve and mental artery exit the body of the mandible, being an important landmark for dentoalveolar surgery.

Materials And Methods: For the assessment of MnF topography, we performed a direct morphometric study and two morphometric imaging studies through cone-beam computed tomography (CBCT) scans and orthopantomography (OPG). The following locations of the MnF were investigated: anterior to the first premolar, at the first premolar level, between the two premolars, at the second premolar level, between the second premolar and the 6-year molar, and at the level of the mesial root of the 6-year molar.

Direct and imaging morphometry for the localization of the mandibular foramen (MF) in dentate and edentulous human subjects.

Background: The mandibular foramen (MF) is the anatomic landmark where the interior alveolar nerve enters the mandibular ramus, and the area of choice where anesthesia of this nerve is performed. The position of the MF can vary, and accurately establishing its location and topographic variations is of great importance for the successful anesthesia of the inferior alveolar nerve.

Materials And Methods: We carried out two morphometric ex vivo studies concerning the topography of the MF, on dry human mandibles coming from dentate and completely edentulous human subjects of known age and gender and an in vivo morphometric study, through cone-beam computed tomography (CBCT) scans, concerning the topography of the MF in human subjects having Kennedy Class I mandibular edentulism.

The Prevalence of HCV Infection and Risk Factors in a Hospital- Based Population Screening, a First Step to the Micro-Elimination of HCV Infection in Medical Institutions from Romania - Results of the HepC ALERT Study.

Background And Aims: Elimination of hepatitis C worldwide is more feasible if micro-elimination screening strategies are adopted. We aimed to screen hepatitis C virus (HCV) in specific high-risk populations in certain sub-regions of Romania and link them to antiviral treatment.

Methods: A multicenter prospective study was conducted among the hospitalized or ambulatory adult patients from March 2019 to March 2020 in more than 20 medical institutions from 4 Romanian cities (Bucharest, Iasi, Timisoara, Cluj-Napoca).

Pre and post-liver transplant outcome of cirrhotic patients with acute on chronic liver failure.

Acute on chronic liver failure (ACLF) is a dynamic syndrome, but frequently associated with a high 1 month mortality rate. This is the first study applying the new European Association for the Study of the Liver- chronic liver failure consortium criteria to explore mortality on the waiting list (WL) and early after liver transplantation (LT) in a cohort of Romanian cirrhotic patients that improved or recovered after an episode of ACLF.To assess frequency and waitlist mortality for different grades of ACLF.

Identification of Lynch syndrome risk variants in the Romanian population.

Two familial forms of colorectal cancer (CRC), Lynch syndrome (LS) and familial adenomatous polyposis (FAP), are caused by rare mutations in DNA mismatch repair genes (MLH1, MSH2, MSH6, PMS2) and the genes APC and MUTYH, respectively. No information is available on the presence of high-risk CRC mutations in the Romanian population. We performed whole-genome sequencing of 61 Romanian CRC cases with a family history of cancer and/or early onset of disease, focusing the analysis on candidate variants in the LS and FAP genes.

Profile of common prostate cancer risk variants in an unscreened Romanian population.

To find sequence variants affecting prostate cancer (PCA) susceptibility in an unscreened Romanian population we use a genome-wide association study (GWAS). The study population included 990 unrelated pathologically confirmed PCA cases and 1034 male controls. DNA was genotyped using Illumina SNP arrays, and 24.

Replication study of 34 common SNPs associated with prostate cancer in the Romanian population.

Prostate cancer is the third-most common form of cancer in men in Romania. The Romanian unscreened population represents a good sample to study common genetic risk variants. However, a comprehensive analysis has not been conducted yet.

Hepatitis Delta Virus Infection in Romania: Prevalence and Risk Factors.

Background: Hepatitis delta virus (HDV) infection is associated with accelerated progression of fibrosis, early occurrence of hepatic decompensation and an increased risk for hepatocellular carcinoma. Epidemiological data on hepatitis delta virus (HDV) in Romania are still lacking.

Aim: To assess the prevalence, virological, clinical and epidemiological features of HDV infection in Romanian patients.

A study based on whole-genome sequencing yields a rare variant at 8q24 associated with prostate cancer.

In Western countries, prostate cancer is the most prevalent cancer of men and one of the leading causes of cancer-related death in men. Several genome-wide association studies have yielded numerous common variants conferring risk of prostate cancer. Here, we analyzed 32.

The prevalence and risk factors of hepatitis B virus infection in an adult population in Romania: a nationwide survey.

Aim: The prevalence and risk factors of hepatitis B virus (HBV) infection in the general population in Romania are still largely unknown.

Methods: A nationwide cross-sectional survey among a Romanian adult population (18-69 years) was conducted during 2006-2008 using a stratified, multistage sampling design. A total of 17 600 individuals were enrolled randomly into the study; the prevalence of chronic HBV infection (HBsAg-positive and anti-HBcAb-positive samples) was assessed on 13 127 individuals (74.

Single nucleotide polymorphisms in colorectal cancer: associations with tumor site and TNM stage.

Background And Aim: Colon tumor carcinogenesis and rectal tumor carcinogenesis have each been associated with different genetic features, but data are still controversial and are insufficient to support their distinct molecular biology. Recently, genome-wide association studies (GWAS) have also found heterogeneity in colorectal cancer (CRC) risks based on population ethnicity and tumor features. Several single nucleotide polymorphism (SNP) markers are described in the literature as having site and/or stage specificity, including rs10795668, rs3802842, rs6983267, and rs4939827.

A germline variant in the TP53 polyadenylation signal confers cancer susceptibility.
