Survey of Informed Consent Procedures in Urology: Disclosing Resident Participation to Patients.

AbstractThe American Urological Association (AUA) and American College of Surgeons (ACS) codes of professionalism require surgeons to disclose the specific roles and responsibilities of trainees to patients during the informed consent process. The objective of this study is to analyze how these requirements are met by urology training programs. An anonymous electronic survey was distributed to the program directors (PDs) of the 143 Accreditation Council for Graduate Medical Education urology residency programs in the United States in 2021.

Characteristics of Medical Schools in the United States Associated With Successful Match into Urology Residency Programs: Analysis of the 2016-2021 Urology Resident Cohort.

Objective: To determine the characteristics of US medical schools associated with successful urology match applicants.

Materials And Methods: Using publicly available data, demographics and bibliometrics were collected for 1814 current urology residents who attend a US-based Accreditation Council for Graduate Medical Education (ACGME) Accredited program, reflecting matched applicants over a 6-year period from 2016-2021. A generated list of US feeder medical schools for urology was analyzed for correlative and predictive factors.

In vivo high-content imaging and regression analysis reveal non-cell autonomous functions of Shroom3 during neural tube closure.

During neural tube closure, neural ectoderm cells constrict their apical surfaces to bend and fold the tissue into a tube that will become the central nervous system. Recent data from mice and humans with neural tube defects suggest that key genes required for neural tube closure can exert non-cell autonomous effects on cell behavior, but the nature of these effects remains obscure. Here, we coupled tissue-scale, high-resolution time-lapse imaging of the closing neural tube of Xenopus to multivariate regression modeling, and we show that medial actin accumulation drives apical constriction non-autonomously in neighborhoods of cells, rather than solely in individual cells.

Single-Port Robotic Radical Prostatectomy: Short-Term Outcomes and Learning Curve.

In 2018, the U.S. Food and Drug Administration approved the da Vinci single-port (SP) system, in which four instruments are still utilized, but enter through a single-site access trocar.

The Ideal Time to Administer Pre-operative Antibiotics: Current and Future Practices.

Background Preoperative antibiotic prophylaxis is a method of administering antibiotics prior to surgical procedures to decrease surgical site infections. The Center for Disease Control and Prevention (CDC) guidelines recommend administering the chosen antibiotic within 60 minutes prior to incision. However, further research can be conducted to explore and determine a more precise and ideal time for preoperative antibiotic prophylaxis.

Impact of medical school responses during the COVID-19 pandemic on student satisfaction: a nationwide survey of US medical students.

Purpose: Medical schools have faced various challenges in preparing their clinical students for the frontlines of a pandemic. This study investigated medical students' satisfaction with their institutions during the coronavirus disease 2019 (COVID-19) pandemic with the intention of guiding educators in future public health crises.

Methods: In this cross-sectional study surveying students in clinical rotations, the primary outcome was overall satisfaction regarding medical schools' responses to the pandemic, and the four secondary outcomes were school communication, exposure to COVID-19, availability of personal protective equipment, and access to COVID-19 testing.

Genomic analysis and long-term outcomes of a phase 1 clinical trial on cytoreductive radical prostatectomy.

Purpose: Approximately 7% of patients with newly diagnosed prostate cancer (PCa) in the US will have have metastatic disease. The dogma that there is no role for surgery in this population has been questioned recently. Here we report long-term outcomes of a phase 1 clinical trial on cytoreductive radical prostatectomy.

Global analysis of cell behavior and protein dynamics reveals region-specific roles for Shroom3 and N-cadherin during neural tube closure.

Failures of neural tube closure are common and serious birth defects, yet we have a poor understanding of the interaction of genetics and cell biology during neural tube closure. Additionally, mutations that cause neural tube defects (NTDs) tend to affect anterior or posterior regions of the neural tube but rarely both, indicating a regional specificity to NTD genetics. To better understand the regional specificity of cell behaviors during neural tube closure, we analyzed the dynamic localization of actin and N-cadherin via high-resolution tissue-level time-lapse microscopy during neural tube closure.

Massively parallel reporter assays discover de novo exonic splicing mutants in paralogs of Autism genes.

To determine the contribution of defective splicing in Autism Spectrum Disorders (ASD), the most common neurodevelopmental disorder, a high throughput Massively Parallel Splicing Assay (MaPSY) was employed and identified 42 exonic splicing mutants out of 725 coding de novo variants discovered in the sequencing of ASD families. A redesign of the minigene constructs in MaPSY revealed that upstream exons with strong 5' splice sites increase the magnitude of skipping phenotypes observed in downstream exons. Select hits were validated by RT-PCR and amplicon sequencing in patient cell lines.

Dissecting the role of lymphadenectomy in the management of renal cell carcinoma: past, present, and future.

Lymph node involvement in renal cell carcinoma (RCC) portends a poor prognosis. However, the role of lymph node dissection (LND) at the time of tumor resection is not fully understood. Conflicting data have been published regarding the survival implications of LND during RCC surgery, and the optimal patient population for which LND might be beneficial has yet to be identified.

Prospective Analyses of Cytokine Mediation of Sleep and Survival in the Context of Advanced Cancer.

Objective: The aims of this study were to examine the potential association between sleep problems, symptom burden, and survival in patients with advanced cancer.

Methods: A prospective study of 294 patients with gastrointestinal cancer administered questionnaires assessing sleep, depression, anxiety, stress, pain, fatigue, and health-related quality of life. Serum levels of cytokines including interleukin (IL)-1α, IL-1β, tumor necrosis factor α, IL-10, IL-2, and interferon-γ were measured to assess biological mediation between sleep and survival.

Characterization of Electrophysiological Propagation by Multichannel Sensors.

Objective: The propagation of electrophysiological activity measured by multichannel devices could have significant clinical implications. Gastric slow waves normally propagate along longitudinal paths that are evident in recordings of serosal potentials and transcutaneous magnetic fields. We employed a realistic model of gastric slow wave activity to simulate the transabdominal magnetogastrogram (MGG) recorded in a multichannel biomagnetometer and to determine characteristics of electrophysiological propagation from MGG measurements.

Simulating a dual-array electrode configuration to investigate the influence of skeletal muscle fatigue following functional electrical stimulation.

A novel, anatomically-accurate model of a tibialis anterior muscle is used to investigate the electro-physiological properties of denervated muscles following functional electrical stimulation. The model includes a state-of-the-art description of cell electro-physiology. The main objective of this work is to develop a computational framework capable of predicting the effects of different stimulation trains and electrode configurations on the excitability and fatigue of skeletal muscle tissue.

Silver nanoparticles induce apoptosis through the toll-like receptor 2 pathway.

Objective: The objective of this study was to evaluate the effects of silver nanoparticles (AgNPs) on the Toll-like receptor 2 (TLR-2) pathway in cultured cells.

Study Design: Human chondrocytes, periodontal ligament (PDL) cells, and SCC-9 cells (squamous cell carcinoma from the tongue) were cultured and subjected to cytotoxicity assays. To evaluate the effects of AgNPs on the TLR-2 pathway, TLR-2 small interfering (si) RNA or TLR-2 antibodies were applied to the chondrocytes, followed by the application of AgNPs.
