Implementation and Utility of the Da Vinci SP (Single Port) in Pediatric Urology.

Purpose Of Review: Detail the evolution, utility, and future directions of the da Vinci SP® in pediatric urology, focusing on perioperative outcomes and intraoperative details.

Recent Findings: The SP has been safely and successfully utilized in various pediatric urological procedures, from pyeloplasty to nephroureterectomy to appendicovesicostomy. Reports indicate mixed operative times but similar hospital stays and postoperative outcomes compared to multiport (MP) robotic surgery.

Total Intravenous Anesthesia with Propofol Reduces Discharge Times Compared with Inhaled General Anesthesia in Shoulder Arthroscopy: A Randomized Controlled Trial.

Background: Shoulder arthroscopy is commonly performed at ambulatory surgical centers (ASCs) with use of an interscalene block and inhaled general anesthesia (IGA). However, an alternative option known as total intravenous anesthesia with propofol (TIVA-P) has shown promising results in reducing recovery time for other surgeries. The objective of this study was to assess whether there is a clinically meaningful difference in post-anesthesia care unit phase-I (PACU-I) time following shoulder arthroscopy between patients receiving an interscalene block with IGA and those receiving an interscalene block with TIVA-P.

Cardiovascular Safety of Degarelix Versus Leuprolide in Patients With Prostate Cancer: The Primary Results of the PRONOUNCE Randomized Trial.

Background: The relative cardiovascular safety of gonadotropin-releasing hormone (GnRH) antagonists compared with GnRH agonists in men with prostate cancer and known atherosclerotic cardiovascular disease remains controversial.

Methods: In this international, multicenter, prospective, randomized, open-label trial, men with prostate cancer and concomitant atherosclerotic cardiovascular disease were randomly assigned 1:1 to receive the GnRH antagonist degarelix or the GnRH agonist leuprolide for 12 months. The primary outcome was the time to first adjudicated major adverse cardiovascular event (composite of death, myocardial infarction, or stroke) through 12 months.

Sexual behaviour, semen quality and fertility of young Border Leicester rams administered melatonin during spring.

This study was conducted to test the hypothesis that between year variability in reproductive response to melatonin treatment of young Border Leicester (BL) rams in spring was related to sexual maturity at the time of treatment. Two variables of sexual maturity (mating behaviour and semen quality) were examined. In Experiment 1, mating activity of melatonin-treated and untreated rams was examined at two sites before a flock mating at one site.

Strategic contracting practices to improve procurement of health commodities.

Public-sector entities responsible for procurement of essential medicines and health commodities in developing countries often lack the technical capacity to efficiently ensure supply security. Under strict public scrutiny and pressures to be transparent, many agencies continue to use archaic procurement methods and to depend on inflexible forecasts and cumbersome tendering processes. On the basis of semi-structured literature reviews and interviews, we identified framework agreements as a strategic procurement practice used by the U.

Positive effects of melatonin treatment on the reproductive performance of young border leicester rams mated to merino ewes in spring: preliminary observations.

Poor reproductive performance of Merino ewe flocks when mated to Border Leicester rams during spring may be due to seasonality of the Border Leicester breed. Two approaches were taken to test this assumption. Six young (12 months old) or six mixed-age (12, 24 and ≥36 months old) Border Leicester rams were either treated or not treated with melatonin implants (2 × 2 design) 6 weeks before the four groups of rams were each put with approximately 300 Merino ewes for an 8-week mating period.

Comparison of viral Env proteins from acute and chronic infections with subtype C human immunodeficiency virus type 1 identifies differences in glycosylation and CCR5 utilization and suggests a new strategy for immunogen design.

Understanding human immunodeficiency virus type 1 (HIV-1) transmission is central to developing effective prevention strategies, including a vaccine. We compared phenotypic and genetic variation in HIV-1 env genes from subjects in acute/early infection and subjects with chronic infections in the context of subtype C heterosexual transmission. We found that the transmitted viruses all used CCR5 and required high levels of CD4 to infect target cells, suggesting selection for replication in T cells and not macrophages after transmission.

CAPRISA 004 tenofovir microbicide trial: no impact of tenofovir gel on the HIV transmission bottleneck.

Alterations of the genital mucosal barrier may influence the number of viruses transmitted from a human immunodeficiency virus-infected source host to the newly infected individual. We used heteroduplex tracking assay and single-genome sequencing to investigate the effect of a tenofovir-based microbicide gel on the transmission bottleneck in women who seroconverted during the CAPRISA 004 microbicide trial. Seventy-seven percent (17 of 22; 95% confidence interval [CI], 56%-90%) of women in the tenofovir gel arm were infected with a single virus compared with 92% (13 of 14; 95% CI, 67%->99%) in the placebo arm (P = .

HIV-1 Populations in Semen Arise through Multiple Mechanisms.

HIV-1 is present in anatomical compartments and bodily fluids. Most transmissions occur through sexual acts, making virus in semen the proximal source in male donors. We find three distinct relationships in comparing viral RNA populations between blood and semen in men with chronic HIV-1 infection, and we propose that the viral populations in semen arise by multiple mechanisms including: direct import of virus, oligoclonal amplification within the seminal tract, or compartmentalization.

PCR Assay Specific for Chicken Feces.

are fecal anaerobic bacteria that are common in the digestive systems and feces of warm-blooded animals. Some strains of have been reported to be host-specific. In this study, strains from chicken feces were examined for their potential use as indicators of chicken fecal contamination.

Maternal-fetal DNA admixture is associated with intrapartum mother-to-child transmission of HIV-1 in Blantyre, Malawi.

Background: The mechanism of mother-to-child transmission (MTCT) of HIV-1 is not well described.

Methods: Of 328 HIV-infected mother-infant pairs, we identified 91 that had discordant angiotensin I-converting enzyme and glutathione S-transferase M1 alleles. Maternal alleles in cord blood were quantified with real-time polymerase chain reaction, as indicators of microtransfusions.

Communication between people with schizophrenia and their medical professionals: a participatory research project.

The authors describe a participatory research project undertaken by a group of people with schizophrenia under the guidance of a university researcher. Participatory research involves members of the research group in meaningful participation in all stages of the research process. In this study, group members chose the topic-experiences with medical professionals-and method of data collection-in-depth interviews that they conducted with each other.
