In conclusion, DSGs play an important role in CRC, and our pipeline is effective to identify them.Sensorineural hearing loss is one of the most common sensory disorders worldwide. Recent advances in vector design have paved the way for investigations into the use of adeno-associated vectors (AAVs) for hearing disorder gene therapy. Numerous AAV serotypes have been discovered to be applicable to inner ears, constituting a key advance for gene therapy for sensorineural hearing loss, where transduction efficiency of AAV in inner ear cells is critical for success. One such viral vector, AAV2/Anc80L65, has been shown to yield high expression in the inner ears of mice treated as neonates or adults. Here, to evaluate the feasibility of prenatal gene therapy for deafness, we assessed the transduction efficiency of AAV2/Anc80L65-eGFP (enhanced green fluorescent protein) after microinjection into otocysts in utero. This embryonic delivery method achieved high transduction efficiency in both inner and outer hair cells of the cochlea. Additionally, the transduction efficiency was high in the hair cells of the vestibules and semicircular canals and in spiral ganglion neurons. Our results support the potential of Anc80L65 as a gene therapy vehicle for prenatal inner ear disorders.With the advent of artificial intelligence (AI) in biostatistical analysis and modeling, machine learning can potentially be applied into developing diagnostic models for interstitial cystitis (IC). In the current clinical setting, urologists are dependent on cystoscopy and questionnaire-based decisions to diagnose IC. This is a result of a lack of objective diagnostic molecular biomarkers. The purpose of this study was to develop a machine learning-based method for diagnosing IC and assess its performance using metabolomics profiles obtained from a prior study. To develop the machine learning algorithm, two classification methods, support vector machine (SVM) and logistic regression (LR), set at various parameters, were applied to 43 IC patients and 16 healthy controls. There were 3 measures used in this study, accuracy, precision (positive predictive value), and recall (sensitivity). Individual precision and recall (PR) curves were drafted. Since the sample size was relatively small, complicated deep learning could not be done. We achieved a 76%-86% accuracy with leave-one-out cross validation depending on the method and parameters set. The highest accuracy achieved was 86.4% using SVM with a polynomial kernel degree set to 5, but a larger area under the curve (AUC) from the PR curve was achieved using LR with a l1-norm regularizer. The AUC was greater than 0.9 in its ability to discriminate IC patients from controls, suggesting that the algorithm works well in identifying IC, even when there is a class distribution imbalance between the IC and control samples. This finding provides further insight into utilizing previously identified urinary metabolic biomarkers in developing machine learning algorithms that can be applied in the clinical setting.

To determine the rate of residual disease and under-staging after primary transurethral resection (TUR) of bladder tumors (TURBT) in tertiary hospitals in Western Australia.

A retrospective study was performed evaluating all patients with TaHG (stage Ta, high-grade), T1LG (stage T1, low-grade) or T1HG (stage T1, high-grade) bladder cancer on primary TURBT conducted between January 1, 2012 and December 31, 2017 at the four largest metropolitan public hospitals in Western Australia. Only patients who underwent repeat resection within 3 months from initial resection were included. Those with previous history of bladder cancer, incomplete follow-up data and visibly incomplete initial resection were excluded. Baseline patient demographics, macroscopic clearance at initial resection, and disease data at initial and repeat resections were recorded.

Sixty-seven patients with a median age of 71 years were included in this study. At initial resection, T1HG was the most common disease stage (64.2%) and detrusor muscle was present in 82.1% of initial resections. At repeat resection, 41.8% of cases had residual disease. The rate of upstaging to muscle-invasive bladder cancer was 3.0%. click here Patients treated by operators with five or less years of formal training did not have a significantly different rate of residual disease from patients treated by operators with more than five years of experience.

Repeat TUR should remain an essential practice due to high rates of residual disease and a small risk of tumor under-staging. The presence of detrusor muscle and macroscopic clearance should not be used as surrogates for adequacy of resection or consideration of avoiding a repeat TUR, even for TaHG disease.

We report our experience of a man who developed extensive bladder wall calcification within three weeks of being treated with just a single 40 mg dose of intravesical mitomycin C for non-muscle invasive, low-grade transitional cell carcinoma of the bladder. To date, only six other cases were reported in the scientific literature in English, all of which used higher doses of mitomycin and had a longer time to diagnosis than this case. We compared the salient points of this case with previously reported cases.Molecular biosignatures of altered cellular landscapes and functions have been casually linked with pathological conditions, which imply the promise of biomarkers specific to bladder diseases, such as bladder cancer and other dysfunctions. Urinary biomarkers are particularly attractive due to costs, time, and the minimal and noninvasive efforts acquiring urine. The evolution of omics platforms and bioinformatics for analyzing the genome, epigenome, transcriptome, proteome, lipidome, metabolome, etc., have enabled us to develop more sensitive and disease-specific biomarkers. These discoveries broaden our understanding of the complex biology and pathophysiology of bladder diseases, which can ultimately be translated into the clinical setting. In this short review, we will discuss current efforts on identification of promising urinary biomarkers of bladder diseases and their roles in diagnosis and monitoring. With these considerations, we also aim to provide a prospective view of how we can further utilize these bladder biomarkers in developing ideal and smart medical devices that would be applied in the clinic.
