Article Abstract
Recurrent implantation failure (RIF) refers to two or more unsuccessful in vitro fertilization embryo transfers in the same individual. Embryonic characteristics, immunological factors, and coagulation factors are known to be the causes of RIF. Genetic factors have also been reported to be involved in the occurrence of RIF, and some single nucleotide polymorphisms (SNPs) may contribute to RIF. We examined SNPs in , , , and , which have been associated with primary ovarian failure. A cohort of 133 RIF patients and 317 healthy controls consisting of all Korean women was included. Genotyping was performed by Taq-Man genotyping assays to determine the frequency of the following polymorphisms: rs6165, rs11893842 and rs35118453, rs9340799 and rs2234693, and rs17003221 and rs3810682. The differences in these SNPs were compared between the patient and control groups. Our results demonstrate a decreased prevalence of RIF in subjects with the rs6165 A>G polymorphism [AA vs. AG adjusted odds ratio (AOR) = 0.432; confidence interval (CI) = 0.206-0.908; = 0.027, AA+AG vs. GG AOR = 0.434; CI = 0.213-0.885; = 0.022]. Based on a genotype combination analysis, the GG/AA ( rs6165/ESR1 rs9340799: OR = 0.250; CI = 0.072-0.874; = 0.030) and GG-CC ( rs6165/ rs3810682: OR = 0.466; CI = 0.220-0.987; = 0.046) alleles were also associated with a decreased RIF risk. Additionally, the rs6165GG and rs17003221TT+TC genotype combination was associated with a decreased RIF risk (OR = 0.430; CI = 0.210-0.877; = 0.020) and increased FSH levels, as assessed by an analysis of variance. The rs6165 polymorphism and genotype combinations are significantly associated with RIF development in Korean women.

Chromosomal Abnormalities in Couples Experiencing Recurrent Implantation Failure in West of Iran: A Case-Control Study.
Mol Genet Genomic Med

Cytogenetic Laboratories, Shahid Beheshti Hospital, Hamadan University of Medical Sciences, Hamadan, Iran.
Background: Recurrent Implantation Failure (RIF) is defined as the inability to establish pregnancy despite high-quality embryo transfer after the application of at least three consecutive in vitro fertilization (IVF)/intracytoplasmic sperm injection-embryo transfer procedures. Chromosomal abnormalities are one of the primary reasons for pregnancy failure, miscarriage, and birth defects in both natural conception and IVF pregnancies. This study was to evaluate the incidence of chromosomal abnormalities in peripheral blood samples from 100 couples who experienced RIF.

Objective: The association between anti-Müllerian hormone (AMH) levels and embryonic aneuploidy rates was investigated by analyzing clinical and embryo laboratory data from patients with preimplantation genetic testing for aneuploidy (PGT-A). However, the nonlinear relationship and threshold effect of AMH on aneuploidy risk remain poorly understood.
Methods: This retrospective study analyzed the clinical data of 819 PGT-A cycles performed between January 2018 and August 2024 at the General Hospital of Northern Theater Command.

Methods: This multicenter study was conducted in Taiwan between September 2023 and June 2024. Clinical specimens were collected from adult patients with presumptive tuberculosis (TB).
Juvenile ossifying fibroma in a 24-year-old female with systemic comorbidities: a rare case report.

Introduction: Juvenile ossifying fibroma (JOF) is a rare, benign, fibro-osseous lesion characterized by aggressive growth and potential for recurrence. It primarily affects children and adolescents, with two histopathological subtypes: trabecular JOF (TrJOF) and psammomatoid JOF (PsJOF). TrJOF typically presents in the jaws of younger individuals, often before the age of 15.

Background: Tuberculosis (TB) diagnosis remains difficult in children under 5 years of age (under-5s), who have high TB morbidity and mortality rates. In a high-burden TB setting, we investigated the diagnostic characteristics of Xpert MTB/RIF Ultra testing of tongue swabs (TS-XU) collected from under-5s.
Methods: In a masked, prospective, observational study, tongue swabs were collected from enrolled hospitalized under-5s deemed high risk for TB disease who were categorized into 1 of the following: confirmed, unconfirmed, or unlikely TB.
