This contamination should be considered in the asepsis protocol of intravitreal injections.
Surgical face masks worn for more than 4 hours presents higher contamination in the PA than those with less use. Bacterial load in the PA is reduced with povidone-iodine on masks used for more than 4 hours. This contamination should be considered in the asepsis protocol of intravitreal injections.
Fibrinolytic shutdown is associated with poor prognosis in adult sepsis, but data in the pediatric population are sparse. This study aimed to identify the association between impaired fibrinolysis and mortality in pediatric septic shock.

A prospective, observational study conducted between August 2019 and August 2020.

PICU at a pediatric tertiary hospital in Hanoi, Vietnam.

Fifty-six pediatric patients who met septic shock criteria were enrolled.

None.

Conventional coagulation tests and rotational thromboelastometry were performed at diagnosis. The fibrinolytic activity on extrinsic pathway thromboelastometry was negatively correlated with the Vasoactive-Inotropic Score at 24 hours post-PICU admission, peak lactate level during the first 24 hours, Pediatric Logistic Organ Dysfunction-2 score, and Pediatric Risk of Mortality-III score (all p < 0.05). Compared with patients with nonovert disseminated intravascular coagulation, dysfunction of less than two organs, and who survived, patients with on pediatric septic shock is associated with an increase in disease severity and mortality. This highlights the need for further investigations regarding whether fibrinolytic therapy improved the outcome of pediatric septic shock.
This study was designed to evaluate practice changes and outcomes over a 10-year period in a large single-center PICU cohort that received continuous renal-replacement therapy.

Retrospective study design.

A multidisciplinary tertiary PICU of a university-affiliated hospital in Guangzhou, China.

All critically ill children who were admitted to our PICU from January 2010 to December 2019 and received continuous renal-replacement therapy were included in this study.

A total of 289 patients were included in the study. Of the two study periods, 2010-2014 and 2015-2019, the proportion of continuous renal-replacement therapy initiation time greater than 24 hours was significantly reduced ([73/223] 32.73% vs. [40/66] 60.60%, p < 0.001), the percentage of fluid overload at continuous renal-replacement therapy initiation was lower (3.8% [1.6-7.2%] vs. 12.1% [6.6-23.3%], p < 0.001), the percentage of regional citrate anticoagulation protocol was increased ([223/223] 100% vs. [15/66] 22.7%, p < 0.001),as improved over past 10 years, and some changes have taken place during these periods. Among them, early initiation of continuous renal-replacement therapy, lower fluid overload, and regional citrate anticoagulation method seems to be related to the improvement of outcome. Ongoing evaluation of the practice changes and quality improvement of continuous renal-replacement therapy for critically ill pediatric patients still need attention.
To evaluate a guideline for antibiotic decisions in children with suspected ventilator-associated infection.

Prospective, observational cohort study conducted in 22 PICUs in the United States and Canada.

PICUs in 22 hospitals from April 2017 to January 2019.

Children less than 3 years old on mechanical ventilation greater than 48 hours who had respiratory secretions cultured and antibiotics initiated for suspected ventilator-associated infection.

After baseline data collection in children with suspected ventilator-associated infection (Phase 1), a consensus guideline was developed for advising antibiotic continuation or stopping at 48-72 hours (Phase 2) and implemented (Phase 3). Guideline-based antibiotic recommendations were provided to the treating clinicians once clinical and microbiologic data were available. Demographic and outcome data were collected, and guideline compliance and antibiotic utilization evaluated for Phase 1 and Phase 3.

Despite education and implementation efforts, guidelinl for improving guideline adherence and antibiotic use in suspected ventilator-associated infection in future studies.
Antibiotic guideline efficacy and safety remain uncertain due to clinician failure to follow the guideline, instead primarily relying on respiratory culture results. Strategies to overcome clinician perceptions of respiratory cultures and other barriers will be vital for improving guideline adherence and antibiotic use in suspected ventilator-associated infection in future studies.
Fluid overload is associated with worse outcomes in adult and pediatric acute respiratory distress syndrome. However, the time-course of fluid overload and its relationship to outcome has not been described. We aimed to determine the relationship between the timing of fluid overload and outcomes over the first 7 days after acute respiratory distress syndrome onset in children.

Retrospective cohort study.

Single tertiary care PICU.

Intubated children with acute respiratory distress syndrome between 2011 and 2019.

None.

Daily and cumulative total fluid intake, total output, urine output, and fluid balance were collected for each 24-hour period from days 1 to 7 after acute respiratory distress syndrome onset. We tested the association between daily cumulative fluid metrics with PICU mortality and probability of extubation by 28 days using multivariable logistic and competing risk regression, respectively. In a subset of children, plasma was collected on day 1 and day 3 of acute respiratory distress soad after day 4 of acute respiratory distress syndrome, but not before, was associated with worse outcomes. Higher angiopoietin-2 predicted subsequent fluid overload. Cyclopamine cost Our results suggest that future interventions aimed at managing fluid overload may have differential efficacy depending on when in the time-course of acute respiratory distress syndrome they are initiated.
To compare clinical characteristics and outcomes of children admitted to the PICU for severe acute respiratory syndrome coronavirus 2-related illness with or without multisystem inflammatory syndrome in children. The secondary objective was to identify explanatory factors associated with outcome of critical illness defined by a composite index of in-hospital mortality and organ system support requirement.

Retrospective cohort study.

Thirty-eight PICUs within the Viral Infection and Respiratory Illness Universal Study registry from March 2020 to January 2021.

Children less than 18 years with severe acute respiratory syndrome coronavirus 2-related illness with or without multisystem inflammatory syndrome in children.

Of 394 patients, 171 (43.4%) had multisystem inflammatory syndrome in children. Children with multisystem inflammatory syndrome in children were more likely younger (2-12 yr vs adolescents; p < 0.01), Black (35.6% vs 21.9%; p < 0.01), present with fever/abdominal pain than cough/dys or greater than or equal to two comorbidities among the multisystem inflammatory syndrome in children cohort. Among nonmultisystem inflammatory syndrome in children patients, the presence of greater than or equal to two comorbidities was associated with greater odds of critical illness (odds ratio 2.95 [95% CI, 1.61-5.40]; p < 0.01).

This study delineates significant clinically relevant differences in presentation, explanatory factors, and outcomes among children admitted to PICU with severe acute respiratory syndrome coronavirus 2-related illness stratified by multisystem inflammatory syndrome in children.

Artificial intelligence (AI) is the ability of a machine, or computer, to simulate intelligent behavior. In medicine, the use of large datasets enables a computer to learn how to perform cognitive tasks, thereby facilitating medical decision-making. This review aims to describe advancements in AI in stone disease to improve diagnostic accuracy in determining stone composition, to predict outcomes of surgical procedures or watchful waiting and ultimately to optimize treatment choices for patients.

AI algorithms show high accuracy in different realms including stone detection and in the prediction of surgical outcomes. There are machine learning algorithms for outcomes after percutaneous nephrolithotomy, extracorporeal shockwave lithotripsy, and for ureteral stone passage. Some of these algorithms show better predictive capabilities compared to existing scoring systems and nomograms.

The use of AI can facilitate the development of diagnostic and treatment algorithms in patients with stone disease. Although the generalizability and external validity of these algorithms remain uncertain, the development of highly accurate AI-based tools may enable the urologist to provide more customized patient care and superior outcomes.

As technology advances, surgical training has evolved in parallel over the previous decade. Training is commonly seen as a way to prepare surgeons for their day-to-day work; however, more importantly, it allows for certification of skills to ensure maximum patient safety. This article reviews advances in the use of machine learning and artificial intelligence for improvements of surgical skills in urology.

Six studies have been published, which met the inclusion criteria. All articles assessed the application of artificial intelligence in improving surgical training. Different approaches were taken, such as using machine learning to identify and classify suturing gestures, creating automated objective evaluation reports, and determining surgical technical skill levels to predict clinical outcomes. The articles illustrated the continuously growing role of artificial intelligence to address the difficulties currently present in evaluating urological surgical skills.

Artificial intelligence allows us to efurgeon feedback.
The purpose of this review was to identify the most recent lines of research focusing on the application of artificial intelligence (AI) in the diagnosis and staging of prostate cancer (PCa) with imaging.

The majority of studies focused on the improvement in the interpretation of bi-parametric and multiparametric magnetic resonance imaging, and in the planning of image guided biopsy. These initial studies showed that AI methods based on convolutional neural networks could achieve a diagnostic performance close to that of radiologists. In addition, these methods could improve segmentation and reduce inter-reader variability. Methods based on both clinical and imaging findings could help in the identification of high-grade PCa and more aggressive disease, thus guiding treatment decisions. Though these initial results are promising, only few studies addressed the repeatability and reproducibility of the investigated AI tools. Further, large-scale validation studies are missing and no diagnostic phase III or higher studies proving improved outcomes regarding clinical decision making have been conducted.
