To characterise the genetic alterations in adult primary uterine rhabdomyosarcomas (uRMSs) and to investigate whether these tumours are genetically distinct from uterine carcinosarcomas (UCSs).

Three tumours originally diagnosed as primary adult pleomorphic uRMS were subjected to massively parallel sequencing targeting 468 cancer-related genes and RNA-sequencing. Mutational profiles were compared with those of UCSs (n=57) obtained from The Cancer Genome Atlas. Sequencing data analyses were performed using validated bioinformatic approaches. Pathogenic TP53 mutations and high levels of genomic instability were detected in the three cases. BAY-293 in vitro uRMS1 harboured a likely pathogenic YTHDF2-FOXR1 fusion. uRMS2 harboured a PPP2R1A hotspot mutation and amplification of multiple genes, including WHSC1L1, FGFR1, MDM2, and CCNE1, whereas uRMS3 harboured an FBXW7 hotspot mutation and an ANKRD11 homozygous deletion. Hierarchical clustering of somatic mutations and copy number alterations revealed that these tumours initially diagnosed as pleomorphic uRMSs and UCSs were similar. Subsequent comprehensive pathological re-review of the three uRMSs revealed previously unidentified minute pan-cytokeratin-positive atypical glands in one case (uRMS3), favouring its reclassification as UCS with extensive rhabdomyosarcomatous overgrowth.

Adult pleomorphic uRMSs harbour TP53 mutations and high levels of copy number alterations. Our findings underscore the challenge in discriminating between uRMS and UCS with rhabdomyosarcomatous differentiation.

To evaluate how different rotational speeds affect the torque/force generation and shaping ability of rotary root canal instrumentation using JIZAI (MANI, Japan) nickel-titanium instruments in continuous rotation and optimum torque reverse (OTR) motion.

Mesial root canals of mandibular molars were instrumented up to size 25, .04 taper using JIZAI instruments, and anatomically matched canals were selected based on geometric features of the canal [canal volume (mm

), surface area (mm

), length, 15°-20° curvature and radius of curvature (4-8mm)] after micro-computed tomographic scanning. An automated root canal instrumentation and torque/force analyzing device was programmed to permit a simulated pecking motion (2seconds downward and 1second upward at 50mm/min). The selected canals were prepared with size 25, .06 taper JIZAI instruments using continuous rotation or OTR motion and further subdivided according to the rotational speed (300 or 500rpm, n=10 each). Real-time clockwise/counterclockwise torque aficantly lower maximum screw-in force and torque value than rotational speed of 300rpm. Continuous rotation and OTR motion performed similarly in shaping the canals.

Under laboratory conditions using JIZAI instruments, rotational speed of 500 rpm generated significantly lower maximum screw-in force and torque value than rotational speed of 300 rpm. Continuous rotation and OTR motion performed similarly in shaping the canals.The increase of the evolutionary pressure will cause phylodynamics changes of viruses. In post-vaccine coverage era, measles viruses face more immune pressure than ever before. Vice versa, the phylodynamic changes may reflect herd immunity level provided by vaccination. In this study, we analyzed phylodynamic characteristics of measles viruses isolated from 2005 to 2017 in Jiangsu province of China using nucleoprotein gene sequences of measles viruses. The phylogenetic tree was constructed with Markov chain Monte Carlo algorithm. The mean gene distance within each group was computed with MEGA7.0 software. Our results showed that a decline trend is observed in the gene distance of nucleoprotein gene with time as well as incidence of measles from epidemic surveillance system. Two clusters of H1a genotype show cocirculation of multiple variants in early years and the disappearance of most variants with time. We explore the phylodynamic of measles virus under high immune pressure. Our findings highlight that phylodynamic of measles viruses is a helpful tool to assess the effectiveness of epidemic control.

Our aim was to evaluate gene expression profiling of fibroblasts from human alveolar mucosa (M), buccal attached gingiva (G) and palatal (P) tissues during early wound healing, correlating it with clinical response.

M, G and P biopsies were harvested from six patients at baseline and 24hr after surgery. Clinical response was evaluated through Early wound Healing Score (EHS). Fibrotic markers expression and autophagy were assessed on fibroblasts isolated from those tissues by Western blot and qRT-PCR. Fibroblasts from two patients were subjected to RT

profiler array, followed by network analysis of the differentially expressed genes. The expression of key genes was validated with qRT-PCR on all patients.

At 24hr after surgery, EHS was higher in P and G than in M. In line with our clinical results, no autophagy and myofibroblast differentiation were observed in G and P. We observed significant variations in mRNA expression of key genes RAC1, SERPINE1 and TIMP1, involved in scar formation; CDH1, ITGA4 and ITGB5, contributing to myofibroblast differentiation; and IL6 and CXCL1, involved in inflammation.

We identified some genes involved in periodontal soft tissue clinical outcome, providing novel insights into the molecular mechanisms of oral repair (ClinicalTrial.gov-NCT04202822).

The aim of our study was to find and map untreated incontinence patients through general practitioner (GP) practices.

General practitioners and their assistants participated in the program (Group A). GPs of all the country were involved in a representative manner. The process of the program was preparing the education program, praxis involvement, participant education, a population screening, and by questionnaire by medical staff. In Group B urological outpatients clinics participated.

A total of 2761 GPs, 3015 nurses, and 110 specialists participated in the program between 2011 and 2019. The population participating in the program was 162,871, 86% womenand 14% men. The age range was 18-96. 68% had urinary incontinence (UI), 76% of patients had stress, and 49% had urge incontinence. Incontinence is very high (98%) among bedridden patients. On average, 20% had very little information, 40% had little information, 33% had enough information about incontinence, and 7% thought they knew everything about it. 41% reported diabetes mellitus, 33% had frequent cough and sneezing, 31% obesity as a risk factor.
