The search for risk factors for rapid progression of hepatic fibrosis (HF) in chronic hepatitis C (CHC) is a topical scientific and practical task. The purpose of the study is to identify clinical and genetic predictors and create the prognostic model of rapidly progressive HF in CHC. A retrospective cohort study of 125 patients with CHC has been carried out. The logistic regression and ROC-analysis have been applied for statistical data processing. The resulting analysis of 46 potential predictors of rapidly progressive HF in CHC identified the following significant ctiteria: male gender - ОR=3.44 [95% СΙ 1.60-7.39], р=0.001; increased levels of alanine aminotransferase (ALT) - ОR=4.93 [95% СΙ 1.54-15.76], р=0.007, particularly, moderate cytolytic activity - ОR=2.36 [95% СΙ 1.08-5.16], р=0.031; aspartate aminotransferase (АSТ) - ОR=3.65 [95% СΙ 1.41-9.43] р=0.007; γ-glutamiltranspeptidase (GGTP) - ОR=3.63 [95% СΙ 1.73-7.61], р=0.001; total bilirubin - ОR=3.53 [95% СΙ 1.47-8.47], р=0.005; alkaline phosphatase - ОR=9.18 [95% 1.11-75.80], р=0.039; alcohol intake>40 g/day (ОR=3.53 [95% СΙ 1.36-9.17], р=0.009), Gln11Gln genotype of the TLR7 gene (ОR=4.56 [95% СΙ 1.57-13.22], р=0.005), presence of chronic cholecystitis and/or pancreatitis (ОR=5.30 [95% СΙ 1.84-15.25], р=0.002). The prognostic model, comprising 6 predictors (level of GGTP>upper limit of normal (ULN), male gender, Gln11Gln genotype of the TLR7 gene chronic cholecystitis and/or pancreatitis, levels of total bilirubin and АSТ>ULN) have been created, demonstrating the statistical significance (p=0.000) and high operational characteristics (sensitivity - 85.5%, specificity - 68.3%, total number of the appropriate assignments - 76.8%, positive and negative predictive value - 72,6% and 82.7%,, respectively, the AUC ROC-curve - 0.840). Use of the created model will help to predict the rapid progression of HF in CHC and form the risk-group, requiring individual approaches to prescribing antiviral therapy for CHC.

Association of vitamin D receptor gene polymorphisms, metabolic features and susceptibility to polycystic ovary syndrome: a preliminary study.
Reprod Biomed Online

UMF Iuliu Haţieganu, Cluj-Napoca, Romania.
Research Question: Are the combined genotypes and haplotypes of vitamin D receptor (VDR) gene polymorphisms (FokI, ApaI and TaqI) associated with susceptibility to polycystic ovary syndrome (PCOS) and metabolic features of the disease?
Design: This case-control study included 46 women with PCOS and 48 controls. Genotypes of the VDR gene were determined using the polymerase chain reaction-restriction fragment length polymorphism method. Waist circumference, and parameters of lipid and glucose metabolism were evaluated in all women.

To analyze whether combinations of polymorphisms within FSHR gene influence ovarian response (OR) to stimulation. A multicenter prospective cohort study was conducted from 11/2016-06/2019 in Europe and Asia including predicted normo-responders under 38y. Patients underwent ovarian stimulation using fixed-dose 150 IU rFSH in a GnRH antagonist protocol.

Article Synopsis
- Crohn's disease affects the small intestine, leading to complex strictures that are hard to diagnose and treat, prompting this study on how effective MRE and DBE-assisted EBD are in addressing these issues.!
- The study looked at 10 patients who underwent DBE-assisted balloon dilatation after being diagnosed with strictures through MRE, showing that MRE accurately identified 75% of these strictures.!
- With a high technical success rate of 72.2%, the study found that DBE was able to dilate most identified strictures without needing any surgical intervention during the follow-up period. !
Association of alpha globin gene copy number with exhaled nitric oxide in a cross-sectional study of healthy Black adults.

Introduction: The genetic determinants of fractional exhalation of nitric oxide (FeNO), a marker of lung inflammation, are understudied in Black individuals. Alpha globin () restricts nitric oxide signalling in arterial endothelial cells via interactions with nitric oxide synthase; however, its role in regulating the release of NO from respiratory epithelium is less well understood. We hypothesised that an gene deletion, common among Black individuals, would be associated with higher FeNO.

Article Synopsis
- The antigen rapid diagnostic test (Ag-RDT) detects SARS-COV-2 proteins using the colloidal gold method, which is crucial for limiting transmission and enabling early treatment.
- A clinical evaluation was conducted using the DEEPBLUE®COVID-19 antigen detection kit on samples from nasal and nasopharyngeal swabs, showing high sensitivity (91.7% for nasal and 96.8% for nasopharyngeal) and 100% specificity for both.
- The study found a significant correlation between the Ag-RDT results and RT-qPCR testing, indicating that the Ag-RDT kit performs comparably to the more established RT-qPCR method.
