Article Abstract

Genome-wide association studies (GWAS) have identified multiple single nucleotide polymorphisms (SNPs) or small indels robustly associated with schizophrenia; however, the functional risk variations remain largely unknown. We investigated the 10q24.32 locus and discovered a 339 bp insertion polymorphism (rs71389983) in complete linkage disequilibrium (LD) with the schizophrenia GWAS risk variant rs7914558. The presence of the insertion at rs71389983 strongly repressed transcriptional activities in luciferase assays. This polymorphism may be a target for future mechanistic research. Our study also underlines the importance and necessity of considering previously underestimated polymorphisms in future genetic studies of schizophrenia.

Two new copepod species of the species-rich genus , collected from temporary water habitats in Southeast Asia, are described. A critical morphological comparison has revealed that the two new species, from Thailand and from Cambodia, closely resemble their respective congeners, (Brehm, 1923) and (Richard, 1894). However, can be distinguished from other congeners, including , by the following characters of the male P5: (1) the inner margin of the right basis has one small semicircular knob and one triangular knob; (2) the right second exopodal segment has a long, slender accessory spine inserted at the proximal third of the outer margin; and (3) the inner margin of the left exopod has a bilobed saw with a series of large denticles and smaller denticles near the distal end.

Background: Hemophilia A (HA) is an X-linked recessive bleeding disorder caused by pathogenic variants in the gene, resulting in deficient coagulation factor VIII activity. Although intron 22 and intron 1 inversions (Inv22 and Inv1) accounts for approximately 50% of severe HA cases, complex structural rearrangements mediated by intron 22 homologous region ( repeats have rarely reported and poorly characterized.

Methods: In this study, we investigated a Chinese severe HA pedigree with a complex rearrangement of gene by integrating 750 K SNP arrays, long-read sequencing (Oxford Nanopore Technologies, ONT), and optical genome mapping (OGM).

Objective(s): To characterize the trajectory of subjective sound quality perception over time in adult cochlear implant (CI) recipients and identify predictors of early and long-term sound quality outcomes.

Methods: In this retrospective analysis, 339 adult CI recipients completed the speech, spatial and qualities of hearing scale (SSQ-12) pre-operatively and at 1, 6, and 12 months post-activation. Demographic, audiometric, and electrode placement data were analyzed using linear mixed effects models to identify predictors of sound quality ratings on the SSQ-12 qualities subscale.

Background: There is increasing social media discourse on inadequate pain management during intrauterine device insertion. While a paracervical block has the most evidence for reducing intrauterine device insertion pain in the ambulatory setting, few studies have explored what factors contribute to paracervical block utilization at the level of the individual patient visit.

Objective: To estimate the utilization rate of pain management techniques, including paracervical block, during intrauterine device insertion and evaluate whether there are patient-based or provider-based factors associated with pain management methods.

Introduction: The aim of this study was to report the outcomes of synthetic mid-urethral slings (MUS) in female patients with spina bifida and stress urinary incontinence (SUI).

Methods: All female patients with spina bifida who were seen at a national referral center between 2007 and 2021 and who had a history of MUS for SUI were included in a retrospective study. The primary outcome of interest was the continence status at 1year as per patients' subjective perception categorized as complete continence, improved continence, unchanged or worsened SUI.
