Peripheral chemoreflex restrains skeletal muscle blood flow during exercise in participants with treated hypertension.

We tested the hypothesis that in human hypertension, an increased tonicity/sensitivity of the peripheral chemoreflex causes a sympathetically mediated restraint of nutritive blood flow to the exercising muscles. Fourteen patients with treated hypertension (age 69 ± 11 years, 136 ± 12/80 ± 11 mmHg; mean ± SD) were studied under conditions of intravenous 0.9% saline (control) and low-dose dopamine (2 µg kg min) to inhibit the peripheral chemoreflex, at baseline, during isocapnic hypoxic rebreathing and during rhythmic handgrip exercise (3 min, 50% maximum voluntary contraction).

Methods: This study adopted a cross-sectional research design.

Study protocol for the Intraoperative Complications Assessment and Reporting with Universal Standards (ICARUS) global cross-specialty surveys and consensus.

Annually, about 300 million surgeries lead to significant intraoperative adverse events (iAEs), impacting patients and surgeons. Their full extent is underestimated due to flawed assessment and reporting methods. Inconsistent adoption of new grading systems and a lack of standardization, along with litigation concerns, contribute to underreporting.

Acceptance of Surgical and Non-surgical Cosmetic Procedures: A Cross-Sectional Study From Jazan, Saudi Arabia.

Background and objective  Cosmetic surgery is a field that primarily focuses on the preservation, rebuilding, or improvement of the physical appearance of an individual through surgical and therapeutic methods. This specialization encompasses various interventions, both surgical, such as blepharoplasty, rhinoplasty, and breast augmentation, and non-surgical, including procedures such as chemical peeling, Botox injections, and dermal fillers. This study aims to assess the acceptance of cosmetic surgeries and non-surgical cosmetic procedures and the reasons for non-acceptance in a population from Jazan, Saudi Arabia.

Robotic Management of Complex Vesicourethral Anastomosis Stenosis With Transperineal Urethral Advancement: A Step-by-Step Technique.

Background: Vesicourethral anastomosis stenosis (VUAS) refers to the diameter narrowing of a vesicourethral anastomosis (VUA). It is a known complication after radical prostatectomy that nowadays presents in less than 1% of these cases. When the lumen narrows sufficiently to impede urine flow, obstructive symptoms arise.

Transperineal vs transrectal magnetic resonance and ultrasound image fusion prostate biopsy: a pair-matched comparison.

The objective of this study was to compare transperineal (TP) versus transrectal (TR) magnetic resonance imaging (MRI) and transrectal ultrasound (TRUS) fusion prostate biopsy (PBx). Consecutive men who underwent prostate MRI followed by a systematic biopsy. Additional target biopsies were performed from Prostate Imaging Reporting & Data System (PIRADS) 3-5 lesions.

Severity Grading Systems for Intraoperative Adverse Events. A Systematic Review of the Literature and Citation Analysis.

Introduction: The accurate assessment and grading of adverse events (AE) is essential to ensure comparisons between surgical procedures and outcomes. The current lack of a standardized severity grading system may limit our understanding of the true morbidity attributed to AEs in surgery. The aim of this study is to review the prevalence in which intraoperative adverse event (iAE) severity grading systems are used in the literature, evaluate the strengths and limitations of these systems, and appraise their applicability in clinical studies.

Bibliometric analysis of academic journal recommendations and requirements for surgical and anesthesiologic adverse events reporting.

Background: Standards for reporting surgical adverse events (AEs) vary widely within the scientific literature. Failure to adequately capture AEs hinders efforts to measure the safety of healthcare delivery and improve the quality of care. The aim of the present study is to assess the prevalence and typology of perioperative AE reporting guidelines among surgery and anesthesiology journals.

Venous capacity and compliance in hypertensive adults: influence of hypoxia and hyperoxia.

In hypertension, the cardiorespiratory responses to peripheral chemoreflex activation (hypoxia) and inactivation (hyperoxia) are reportedly augmented, but the impact on peripheral venous function is unknown. We tested the hypothesis that in hypertensives, both hypoxia and hyperoxia evoke more pronounced changes in lower limb venous capacity and compliance, than in age-matched normotensives. In 10 hypertensive [HTN: 7 women; age: 71.

Central and peripheral chemoreflexes in humans with treated hypertension.

Increased peripheral chemoreflex sensitivity is a pathogenic feature of human hypertension (HTN), while both central and peripheral chemoreflex sensitivities are reportedly augmented in animal models of HTN. Herein, we tested the hypothesis that both central and combined central and peripheral chemoreflex sensitivities are augmented in HTN. Fifteen HTN participants (68 ± 5 years; mean ± SD) and 13 normotensives (NT; 65 ± 6 years) performed two modified rebreathing protocols in which the partial pressure of end-tidal carbon dioxide ( ) progressively increased while the partial pressure of end-tidal oxygen was clamped at either 150 mmHg (isoxic hyperoxia; central chemoreflex activation) or 50 mmHg (isoxic hypoxia; combined central and peripheral chemoreflex activation).

Robotic-assisted Simple Prostatectomy: An Intrafascial Approach for a Prostate of 470 g.

Background: Simple prostatectomy has been established as a management option for lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH) with glands larger than 80 cc. Robotic-assisted simple prostatectomy (RASP) has been established as a safe and effective management option. This has been reported in multiple studies comparing it with the open approach where no statistically significant differences in complication rates have been found.

Automated Capture of Intraoperative Adverse Events Using Artificial Intelligence: A Systematic Review and Meta-Analysis.

Intraoperative adverse events (iAEs) impact the outcomes of surgery, and yet are not routinely collected, graded, and reported. Advancements in artificial intelligence (AI) have the potential to power real-time, automatic detection of these events and disrupt the landscape of surgical safety through the prediction and mitigation of iAEs. We sought to understand the current implementation of AI in this space.
