Based on the diagnostic results, two families underwent prenatal diagnosis and had unaffected babies. The incorporation of exome-based CNV detection into conventional SNV/Indel analysis for a single trio-WES test significantly improved the diagnostic rate, making WES a more powerful, practical, and cost-effective tool in the clinical diagnosis of NDDs.
Despite adequate medical treatment, many young adults with haemophilia develop joint alterations-especially in ankles and knees. Undetected over years, subtle structural changes cause subclinical symptoms, before problems become obvious. To objectify these silent pressure pains, the pressure pain threshold (PPT) can be measured by algometry.
The aim was to investigate and compare the effect of age on PPTs in asymptomatic ankles and knees between boys and young adults with haemophilia and age-matched controls, in order to gain better knowledge about the alteration of the periarticular structures with increasing age.
Nineteen persons with haemophilia (PwH; severe or moderate; 8-30years) and 19 age-matched controls with ‘healthy’ ankles and knees were recruited. Asymptomatic joints with a Haemophilia Joint Health Score=0 were included. The PPT was measured on four periarticular points per joint, and the data were analysed with a linear mixed model.
The PPT of the control group increased with age, whereas the PPT of the PwH decreased. The difference in age effect per year in kPa between PwH and controls was as follows β [95%-CI] -15.41 [-31.63; 0.79]. Although the result was not statistically significant (p=.08), a clear tendency was shown.
The results suggest that subclinical alterations in the periarticular structures of these joints may evolve unnoticed over time. However, further research is warranted to determine whether this observed trend is confirmed in a larger sample and at what age the PPT begins to decrease in PwH compared to controls.

To determine the effect of prostatic radiation therapy (RT) on bladder contractility and morphology, and axon, or neuron profiles within the detrusor and major pelvic ganglia (MPG) in male rats.
Male Sprague-Dawley rats (8 weeks) received a single dose of prostatic RT (0 or 22 Gy). Bladders and MPG were collected 2- and 10-weeks post-RT. Detrusor contractile responses to carbachol and electrical field stimulation (EFS) were measured. Bladders were stained with Masson’s trichrome, and antibodies for nonspecific neuronal marker, cholinergic nerve marker choline acetyltransferase (ChAT), and alpha-smooth muscle actin. MPG gene expression was assessed by quantitative polymerase chain reaction for ubiquitin carboxy-terminal hydrolase L1 (Uchl1) and Chat.
At 2 weeks post-RT, bladder smooth muscle, detrusor cholinergic axon profiles, and MPG Chat gene expression were increased (p < .05), while carbachol and EFS-mediated contractions were decreased (p < .05). In contrast, at 10 weeks post-RT, nerve-mediatong-term changes to the MPG and increased bladder cholinergic axons may contribute to RT-induced bladder dysfunction in prostate cancer survivors.Heteroatom containing polymers have strong potential as sustainable replacements for petrochemicals, show controllable monomer-polymer equilibria and properties spanning plastics, elastomers, fibres, resins, foams, coatings, adhesives and self-assembled nanostructures. Their current and future applications span packaging, house-hold goods, clothing, automotive components, electronics, optical materials, sensors and medical products. An interesting route to these polymers is the catalysed ring-opening copolymerisation (ROCOP) of heterocycles and heteroallenes. It is a living polymerization, occurs with high atom economy and creates precise, new polymer structures inaccessible by traditional methods. In the last decade there has been renaissance in research and increasing examples of commercial products made using ROCOP. It is better known in the production of polycarbonates and polyesters but is also a powerful route to make N-, S- and other heteroatom containing polymers, including polyamides, polycarbamates, polythioesters and others. This review presents an overview of the different catalysts, monomer combinations and polymer classes accessed by heterocycle/heteroallene ROCOP. It aims to provide a guide for users both to the catalysis and the resulting materials properties as well as highlighting opportunities for future research and applications.Endometrial neuroendocrine carcinoma is a rare disease with unknown clinicopathological and molecular characteristics. Therefore, we conducted the present study to elucidate the clinicopathological and molecular characteristics of endometrial neuroendocrine carcinoma, as compared to conventional endometrial carcinoma, and to determine the origin of the former. We analyzed 22 endometrial neuroendocrine carcinomas and 22 conventional endometrial neoplasia cases with respect to clinical, histological and genetic features. Of these, 21/22 neuroendocrine carcinoma cases were admixed carcinomas, with 15 admixed with endometrioid adenocarcinoma. Genetic analysis of hotspot mutations in 50 cancer-related genes revealed that the neuroendocrine carcinoma group carried mutations in PIK3CA (12/22 cases; 54%) and PTEN (8/22 cases; 36%), commonly encountered in endometrioid adenocarcinoma. Comparative statistical analysis of neuroendocrine carcinoma and conventional endometrial neoplasia cases showed a significant trend only in PIK3CA mutation. Moreover, in six mixed-type neuroendocrine carcinoma cases, macrodissection was used to separate the neuroendocrine carcinoma and endometrioid adenocarcinoma components for next-generation sequencing, which revealed several mutations common among the two. These findings suggest that endometrial neuroendocrine carcinoma could originate from conventional endometrial neoplasia, especially endometrioid adenocarcinoma.
