85; 95% confidence interval [CI] 2.17-3.75; p < 0.00001), and further subgroup analysis strengthened the outcome, with minor heterogeneity in non-Asian countries. In contrast, the early mortality was not significantly different between the PNH+ and PNH- groups (OR 0.54; 95% CI 0.26-1.10; p = 0.09).

The meta-analysis suggested an evidence-based role for PNH clones in predicting a better response in AA patients with immunosuppression.

The aims of the study were to assess the false-positive and uninformative test rate with first trimester cell-free DNA (cfDNA) screening for common trisomies and microdeletion 22q11.2 (22q11.2DS) and to examine women's attitudes toward such an approach.

This is a prospective study at the Prenatal Medicine Department of the University of Tübingen, Germany, at 11-13 weeks. In all pregnancies, a detailed ultrasound examination was carried out, followed by a cfDNA analysis for common trisomies and 22q11.2DS. In cases where the cfDNA analysis indicated 22q11.2DS, invasive prenatal diagnostic testing and parental testing were performed. selleck After delivery, a detailed neonatal clinical examination was carried out including further genetic testing. Prior to counselling about the study, we asked the pregnant women who were potentially eligible for the study to anonymously report on their knowledge about 22q11.2DS.

A total of 1,127 pregnancies were included in the final analysis of the study. The first cfDNA test was uninformative in 15 (1.33%) pregnancies. In 10 (0.89%) cases, the test remained uninformative, even after the second blood sample. There were 3 (0.27%) cases with a positive cfDNA test for 22q11.2DS. In all, 983 women returned the anonymous questionnaire prior to study participation. Only 80 (8.1%) women responded that they felt familiar or very familiar with 22q11.2DS.

The addition of 22q11.2DS in first trimester cfDNA screening for common trisomies is feasible. The uninformative test rate for common trisomies and 22q11.2DS is 0.9%, and the false-positive rate for 22q11.2DS is 0.3%. Awareness and education around 22q11.2DS should be improved.

Fluctuating hearing loss is a distinctive feature caused by SLC26A4 variants. We investigated whether cochlear implantation had protective or deleterious effect on hearing fluctuation in patients with biallelic SLC26A4 variants.

Patients with biallelic SLC26A4 variants (N = 16; age = 10.24 ± 9.20 years) who had unilateral cochlear implantation and consecutive postsurgical, bilateral pure-tone audiograms more than 3 times were selected. We retrospectively reviewed the patients' medical records from 2008 to 2019 obtained from a tertiary medical center and used the auditory threshold change (Shift) over time as a marker of hearing fluctuation. Fluctuation events were counted, and the Shift of the implanted and contralateral ears was compared using logistic regression with a generalized estimating equation and linear mixed model. A total of 178 values were included.

The odds of fluctuating hearing frequency were 11.185-fold higher in the unimplanted ears than in the implanted ears postoperatively (p = 0.001). The extent of fluctuation at 250 and 500 Hz was also significantly lower in the implanted ears than in the unimplanted ears after adjusting for every other effect (p = 0.003 and p < 0.001, respectively). Notably, higher residual hearing was rather associated with lesser fluctuation in frequency and the extent of fluctuation at 500 Hz, indicating residual hearing function is not the positive predictor for hearing fluctuation.

In patients with biallelic SLC26A4 variants, cochlear implantation may reduce the frequency and extent of hearing fluctuations.

The only causal therapy is fetoscopic laser surgery (FLS). The aims of this study were to analyze the long-term outcome of monochorionic twins treated by FLS, including their school career, need for therapy and special aid equipment, and free-time activities, and compare their outcome to matched dichorionic twins.

Among the 57 women treated at a single fetal treatment center between 2008 and 2017 with FLS because of twin-to-twin transfusion syndrome, 25 women with 42 children were included in the FLS group. The control group consisted of 16 dichorionic twin pairs matched for birth year, gestational age (GA), birth weight, and sex. The long-term outcome was assessed by a parental questionnaire and a standardized neurodevelopmental examination for children born before 32 gestational weeks or with a birth weight lower than 1500 g. They were also registered into the Swiss Neonatal Network database. The primary outcome was event-free survival, defined as normal neurology, behavior, vision, and hearing. The sec outcome of dichorionic twins. Long-term neurodevelopment in the cohort was mainly dependent on GA at birth.

Semicircular canal dehiscence (SCD) is defined as a defect of the bone overlying the semicircular canal. It has a relatively high prevalence of 3% in the general population, which makes it likely that a certain number of patients receiving a cochlear implant (CI) would have it. However, little is known about the influence of SCD on the CI outcome. Therefore, the aim of this study was to determine the influence of SCD on CI outcome with regard to short- and long-term word perception and hearing preservation.

This study was a retrospective analysis of postoperative word perception ability in the electric-only condition after 6, 12, and ≥18 months and of hearing preservation 4 weeks after surgery in CI recipients with and without SCD. All patients received a preoperative 1.5- or 3-tesla magnetic resonance imaging.

Fifty-five patients were included. Forty-eight patients (87%) had no SCD, and 7 patients (13%) had SCD. Mean postoperative word perception scores were 66% in the non-SCD group versus 50% in the SCD group (p = 0.
