We illustrate that we can successfully recover the unknowns separating both tonic and phasic components from both experimental and simulated data (with R

> 0.95). Further, we successfully demonstrate our ability to automatically identify sparsity level for the neural stimuli and smoothness level for the tonic component.

Our generalized-cross-validation-based novel method for SC signal decomposition successfully addresses previous challenges and retrieves a physiologically plausible solution.

Accurate decomposition of SC could potentially improve cognitive stress tracking in patients with mental disorders.

However, neuronal cell type diversity within the VPH is poorly understood, an impediment to deconstructing the roles of distinct VPH circuits in physiology and behavior. To address this question, we employed a droplet-based single-cell RNA sequencing (scRNA-seq) approach to systematically classify molecularly distinct cell populations in the mouse VPH. Analysis of >16,000 single cells revealed 20 neuronal and 18 non-neuronal cell populations, defined by suites of discriminatory markers. We validated differentially expressed genes in selected neuronal populations through fluorescence in situ hybridization (FISH). Focusing on the mammillary bodies (MB), we discovered transcriptionally-distinct clusters that exhibit neuroanatomical parcellation within MB subdivisions and topographic projections to the thalamus. This single-cell transcriptomic atlas of VPH cell types provides a resource for interrogating the circuit-level mechanisms underlying the diverse functions of VPH circuits.

Several studies addressed the role of testicular sperm aspiration with intracytoplasmic sperm injection (ICSI) in azoospermic men but few have included non- azoospermic men. The aim of this study was to evaluate testicular sperm aspiration (TESA) sperm retrieval rates and ICSI outcomes in men with severe oligozoospermia.

Data were collected retrospectively from 88 consecutive, non-azoospermic, infertile men with idiopathic severe oligozoospermia who underwent TESA between January 2011 and January 2018. Patients were categorized into four groups according to sperm concentration <5 and >1 million/ml (group 1), <1 and > 0.1 million/ml (group 2), <0.1 million/ml (group 3) and cryptozoospermia (group 4).

Mean male age was 37±7 years and the mean female age was 33±4 years. Sperm was recovered successfully in 90% (79/88) of the men overall and in 100% (30/30) of the men in group 1, 97% (29/30) of the men in group 2, 88% (15/17) of the men in group 3, and 45% (5/11) of the men in group 4. Most (65%, 57/88) of the couples had an embryo transfer (ET). The overall clinical pregnancy rate per ET was 46% (26/57). The clinical pregnancy rates (per ET) were 43% (9/21) in group 1, 65% (13/20) in group 2, 36% (4/11) in group 3 and 0% (0/5) in group 4.

Our data indicate TESA allows for high sperm retrieval rates and acceptable ICSI pregnancy rates in men with severe oligozoospermia. However, in our experience, TESA sperm retrieval rates and ICSI outcomes are poor in cryptozoospermic men.

We sought to review outcomes of urethrovaginal fistula (UVF) repair, with or without concurrent fascial sling placement.

All patients diagnosed with UVF at our center from 1988-2017 were included in this study. Patient charts were reviewed from a prospectively kept fistula database, and patient characteristics and surgical outcomes were described. Descriptive statistics were applied to compare complication rates between patients with or without fascial sling placement at the time of UVF repair.

A total of 41 cases of UVF were identified, all of which underwent surgical repair. Median age at diagnosis was 49 years (interquartile range [IQR] 35-62). All patients had undergone pelvic surgery. UVF etiology was secondary to stress urinary incontinence (SUI) surgery in 17 patients (41%) and urethral diverticulum repair in seven patients (17%). The most common presenting symptom was continuous incontinence in 19 patients (46%). Nineteen patients had a fascial sling placed at the time of surgery (46%), with no significant difference in complication rates (26% vs. 23%, p=0.79). Two patients had Clavien-Dindo grade I complications (5%) and one had a grade III complication (2%). Four patients had long-term complications (10%), including urinary retention, chronic pain, and urethral stricture. Two patients had UVF recurrence (5%). Median followup after surgery was 21 months (IQR 4-72).

UVF should be suspected in patients with continuous incontinence following a surgical procedure. selleckchem Most UVF surgical repairs are successful and can be done with concurrent placement of a fascial sling.

Fournier's gangrene (FG) is a necrotizing infection of the genitalia. Time from to surgical intervention is a critical determinant of prognosis. We sought to investigate whether patients from rural locations have worse clinical outcomes given distance from a tertiary center.

The Manitoba Intensive Care Unit (ICU) registry includes patients who have been admitted into ICUs across Manitoba. We identified patients admitted with FG from February 1999 to October 2019. Age, gender, Charlson comorbidity index (CCI), presence of colostomy and scrotal debridement, length of stay (LOS), and mortality outcomes were obtained. Patients were categorized as being rural or urban.

From 1999-2019, a total of 79 patients were admitted with FG. The median age was 60 years [interquartile range [IQR] 48-67). The mortality rate during hospitalization was 16.5%. There was no statistically significant difference in the number of deaths for patients from urban vs. rural dwellings (9/47 [19.1%] vs. 4/32 [12.5%], p=0.434]. A comparison of the 66 (83.
