RESUMEN
BACKGROUND: The end of 2019 marked the emergence of the COVID-19 pandemic. Public avoidance of health care facilities, including the emergency department (ED), has been noted during prior pandemics. OBJECTIVE: This study described pandemic-related changes in adult and pediatric ED presentations, acuity, and hospitalization rates during the pandemic in a major metropolitan area. METHODS: The study was a cross-sectional analysis of ED visits occurring before and during the pandemic. Sites collected daily ED patient census; monthly ED patient acuity, as the Emergency Severity Index (ESI) score; and disposition. Prepandemic ED visits occurring from January 1, 2019 through December 31, 2019 were compared with ED visits occurring during the pandemic from January 1, 2020 through March 31, 2021. The change in prepandemic and pandemic ED volume was found using 7-day moving average of proportions. RESULTS: The study enrolled 83.8% of the total ED encounters. Pandemic adult and pediatric visit volume decreased to as low as 44.7% (95% CI 43.1-46.3%; p < 0.001) and 22.1% (95% CI 19.3-26.0%; p < 0.001), respectively, of prepandemic volumes. There was also a relative increase in adult and pediatric acuity (ESI level 1-3) and the admission percentage for adult (20.3% vs. 22.9%; p < 0.01) and pediatric (5.1% vs. 5.6%; p < 0.01) populations. CONCLUSIONS: Total adult and pediatric encounters were reduced significantly across a major metropolitan area. Patient acuity and hospitalization rates were relatively increased. The development of strategies for predicting ED avoidance will be important in future pandemics.

To examine the potential for respiratory transmission of rotavirus, we systematically assessed if rotavirus RNA is detectable by real-time quantitative reverse transcription-polymerase chain reaction from nasal and oropharyngeal swab specimens of Bangladeshi children with acute rotavirus gastroenteritis. Forehead swabs were collected to assess skin contamination. Among 399 children aged <2 years hospitalized for gastroenteritis during peak rotavirus season, rotavirus RNA was detected in stool, oral, nasal and forehead swab specimens of 354 (89%). A subset was genotyped; genotype was concordant within a child's specimen set and several different genotypes were detected across children. These findings support possible respiratory transmission of rotavirus and warrant further investigation.

This study reports the coding-complete genome sequences of three rotavirus A (RVA) reference strains previously adapted in tissue culture: RVA/Mouse-tc/USA/EDIM/XXXX/G16P[16] with a G16-P[16]-I7-R7-C7-M8-A7-N7-T10-E7-H9 genotype constellation, RVA/Human-tc/USA/Ph158/1998/G9P[6] with a G9-P[6]-I2-R2-C2-M2-A2-N2-T2-E2-H2 genotype constellation, and RVA/Human-tc/USA/CC425/1998/G3P[9] with a G3-P[9]-I2-R2-C2-M2-A3-N2-T1-E2-H3 genotype constellation.
RESUMEN
Introduction: We sought to examine the practice patterns of pain management in the emergency room (ER) for renal colic and the impact of opioid prescriptions on return ER visits and persistent opioid use. Methods: TriNetX is a collaborative research enterprise that collects real-time data from multiple health care organizations within the United States. The Research Network obtains data from electronic medical records and the Diamond Network provides claims data. We queried the Research Network for adults who visited the ER for urolithiasis, stratified by receipt of oral opioid prescriptions, to calculate the risk ratio (RR) of patients returning to the ER within 14 days and persistent opioid use ≥6 months from the initial visit. Propensity score matching was performed to control for confounders. The analysis was repeated in the Diamond Network as a validation cohort. Results: There were 255,447 patients in the research network who visited the ER for urolithiasis, of whom 75,405 (29.5%) were prescribed oral opioids. Black patients were less likely to receive opioid prescriptions than other races (p < 0.001). After propensity score matching, patients who were prescribed opioids had an increased risk of a return ER visit (RR 1.25, confidence interval [95% CI] 1.22-1.29, p < 0.001) and persistent opioid use (RR 1.12, 95% CI 1.11-1.14, p < 0.001) compared with patients who were not prescribed opioids. These findings were confirmed in the validation cohort. Conclusions: A significant proportion of patients presenting to the ER for urolithiasis receive opioid prescriptions, which carries a markedly increased risk of return ER visits and long-term opioid use.

Species A rotaviruses (RVA) still play a major role in causing acute diarrhea in children under five years old worldwide. Currently, an 11-gene classification system is used to designate the full genotypic constellations of circulating strains. Viral proteins and non-structural proteins in the order VP7-VP4-VP6-VP1-VP2-VP3-NSP1-NSP2-NSP3-NSP4-NSP5/6 are represented by the genotypes Gx-P[x]-Ix-Rx-Cx-Mx-Ax-Nx-Tx-Ex-Hx, respectively. In Benin, ROTAVAC® vaccine was introduced into the Expanded Programme on Immunization in December 2019. To monitor circulating RVA strains for changes that may affect vaccine performance, in-depth analysis of strains prior to vaccine introduction are needed. Here we report, the whole-gene characterization (11 ORFs) for 72 randomly selected RVA strains of common and unusual genotypes collected in Benin from the 2016 to 2018 seasons. The sequenced strains were 15 G1P[8], 20 G2P[4], 5 G9P[8], 14 G12P[8], 9 G3P[6], 2 G1P[6], 3 G2P[6], 2 G9P[4], 1 G12P[6], and 1 G1G9P[8]/P[4]. The study strains exhibited two genetic constellations designed as Wa-like G1/G9/G12-P[6]/P[8]-I1-R1-C1-M1-A1-N1-T1-E1-H1 and DS-1-like G2/G3/G12-P[4]/P[6]-I2-R2-C2-M2-A2-N2-T2-E2-H2. Genotype G9P[4] strains possessed a DS-1-like genetic constellation with an E6 NSP4 gene, G9-P[4]-I2-R2-C2-M2-A2-N2-T2-E6-H2. The mixed genotype showed both Wa-like and DS-1-like profiles with a T6 NSP3 gene G1/G9P[8]/[4]-I1/I2-R1/R2-C1/C2-M1/M2-A1/A2-N1/N2-T1/T6-E1/E6-H1/H2. At the allelic level, the analysis of the Benin strains, reference strains (with known alleles), vaccine strains (with known alleles) identified 2-13 and 1-17 alleles for DS-1-like and Wa-like strains, respectively. Most of the study strains clustered into previously defined alleles, but we defined 3 new alleles for the VP7 (G3 = 1 new allele and G12 = 2 new alleles) and VP4 (P[4] = 1 new allele and P[6] = 2 new alleles) genes which formed the basis of the VP7 and VP4 gene clusters, respectively. For the remaining 9 genes, 0-6 new alleles were identified for both Wa-like and DS-1-like strains. This analysis of whole genome sequences of RVA strains circulating in Benin described genetic point mutations and reassortment events as well as novel alleles. Further detailed studies on these new alleles are needed and these data can also provide a baseline for studies on RVA in the post-vaccination period.

BACKGROUND: A pediatric emergency medicine and critical care fellowship was recently developed in Kenya through the University of Nairobi/Kenyatta National Hospital and AIC Kijabe Hospital. As part of this training, a week-long trauma and emergency medicine course was developed with emphasis on trauma and emergency medicine procedures. Given limited resources, we developed a course with simulation of procedures centered around utilization of a goat cadaver. OBJECTIVE: The aim of the study was to describe fellow and faculty experiences and perspectives when using a goat cadaver to teach emergency medicine procedures by simulation in Kijabe, Kenya. METHODS: A 5-day course was given to 2 fellows with a variety of didactics and simulations after which fellows completed a questionnaire to rate their satisfaction with the content and teaching effectiveness. RESULTS: The course was rated very highly, with an average content satisfaction score of 4.5 5 and average teaching effectiveness score of 4.4 of 5. Qualitative faculty feedback was positive, with specific learnings allowing ongoing adaptation of this model. CONCLUSIONS: A goat cadaver is a cost-effective resource not often considered that can be adequately used to teach several emergency medicine skills by simulation.

PURPOSE OF REVIEW: Residency training is a pivotal educational step on the road to becoming a urologist. It combines both clinical and surgical instruction with the goal of producing proficient and compassionate surgeons and clinicians. In this review, we employ a SWOT analysis (Strengths, Weaknesses, Opportunities, and Threats) to investigate the current state of urologic residency training. RECENT FINDINGS: Urology remains an attractive and competitive residency with varied and complex surgical and medical training. Areas for improvement include standardization of evaluation and feedback, improving resident wellness, and expanding the use of surgical simulation. Workforce issues such as the predicted urologist supply deficit and poor readiness to enter the business of medicine can be addressed at the residency level. Failure to attract and retain underrepresented minorities, increasing burden of student debt, and resident burnout are serious threats to our field. Using a SWOT analysis we identify key areas for expansion, underscore valuable strengths, and provide a working roadmap for improvement of these formative years.

For over a decade, the New Vaccine Surveillance Network (NVSN) has conducted active rotavirus (RVA) strain surveillance in the USA. The evolution of RVA in the post-vaccine introduction era and the possible effects of vaccine pressure on contemporary circulating strains in the USA are still under investigation. Here, we report the whole-gene characterization (eleven ORFs) for 157 RVA strains collected at seven NVSN sites during the 2014 through 2016 seasons. The sequenced strains included 52 G1P[8], 47 G12P[8], 18 G9P[8], 24 G2P[4], 5 G3P[6], as well as 7 vaccine strains, a single mixed strain (G9G12P[8]), and 3 less common strains. The majority of the single and mixed strains possessed a Wa-like backbone with consensus genotype constellation of G1/G3/G9/G12-P[8]-I1-R1-C1-M1-A1-N1-T1-E1-H1, while the G2P[4], G3P[6], and G2P[8] strains displayed a DS-1-like genetic backbone with consensus constellation of G2/G3-P[4]/P[6]/P[8]-I2-R2-C2-M2-A2-N2-T2-E2-H2. Two intergenogroup reassortant G1P[8] strains were detected that appear to be progenies of reassortment events between Wa-like G1P[8] and DS-1-like G2P[4] strains. Two Rotarix® vaccine (RV1) and two RV5 derived (vd) reassortant strains were detected. Phylogenetic and similarity matrices analysis revealed 2-11 sub-genotypic allelic clusters among the genes of Wa- and DS-1-like strains. Most study strains clustered into previously defined alleles. Amino acid (AA) substitutions occurring in the neutralization epitopes of the VP7 and VP4 proteins characterized in this study were mostly neutral in nature, suggesting that these RVA proteins were possibly under strong negative or purifying selection in order to maintain competent and actual functionality, but fourteen radical (AA changes that occur between groups) AA substitutions were noted that may allow RVA strains to gain a selective advantage through immune escape. The tracking of RVA strains at the sub-genotypic allele constellation level will enhance our understanding of RVA evolution under vaccine pressure, help identify possible mechanisms of immune escape, and provide valuable information for formulation of future RVA vaccines.
RESUMEN
Since 2013, group A rotavirus strains characterized as novel DS-1-like intergenogroup reassortant "equine-like G3" strains have emerged and spread across 5 continents among human populations in at least 14 countries. Here, we report a novel one-step TaqMan quantitative real-time reverse transcription-PCR assay developed to genotype and quantify the viral load for samples containing rotavirus equine-like G3 strains. Using a universal G forward primer and a newly designed reverse primer and TaqMan probe, we developed and validated an assay with a linear dynamic range of 227 to 2.3 × 109 copies per reaction and a limit of detection of 227 copies. The percent positive agreement, percent negative agreement, and precision of our assay were 100.00%, 99.63%, and 100.00%, respectively. This assay can simultaneously detect and quantify the viral load for samples containing DS-1-like intergenogroup reassortant equine-like G3 strains with high sensitivity and specificity, faster turnaround time, and decreased cost. It will be valuable for high-throughput screening of stool samples collected to monitor equine-like G3 strain prevalence and circulation among human populations throughout the world.

OBJECTIVE: Rotavirus A (RVA) remains the main causative agent of gastroenteritis in young children and the young of many mammalian and avian species. In this study we describe a RVA strain detected from a 6-month-old child from Central African Republic (CAR). RESULTS: We report the 11 open reading frame sequences of a G29-P[6]-I2-R2-C2-M2-A2-N2-T2-E2-H2 rotavirus strain, RVA/Human-wt/CAR/CAR91/2014/G29P[6]. Nine genes (VP1-VP3, VP6, NSP1-NSP5) shared 90-100% sequence similarities with genogroup 2 rotaviruses. Phylogenetically, backbone genes, except for VP3 and NSP4 genes, were linked with cognate gene sequences of human DS-1-like genogroup 2, hence their genetic origin. The VP3 and NSP4 genes, clustered genetically with both human and animal strains, an indication genetic reassortment human and animal RVA strains has taken place. The VP7 gene shared nucleotide (93-94%) and amino acid (95.5-96.7%) identities with Kenyan and Belgian human G29 strains, as well as to buffalo G29 strain from South Africa, while the VP4 gene most closely resembled P[6]-lineage I strains from Africa and Bangladesh (97%).

BACKGROUND: Rotavirus is a common cause of severe pediatric acute gastroenteritis. Two vaccines are licensed in the United States and have demonstrated high effectiveness against moderate to severe disease. However, fewer data are available on rotavirus vaccine effectiveness (VE) against milder disease. METHODS: We leveraged active surveillance data from Kaiser Permanente Northwest to calculate rotavirus VE against medically attended rotavirus illness among age-eligible children. We utilized a test-negative case-control design and applied 4 distinct case definitions based on reverse transcription-quantitative real-time PCR (qRT-PCR) assay and enzyme immunoassay (EIA) test results. VE was calculated as 100 × (1 - odds ratio), and models were adjusted for age group. RESULTS: The VE analysis population comprised 842 children, 799 (95%) of whom had mild disease requiring at most a clinic visit and 698 (83%) of whom were fully vaccinated against rotavirus. Age-adjusted VE was 70% (95% confidence interval [CI], 37-86%) against disease defined solely by qRT-PCR results, 72% (95% CI, 31-89%) against disease as defined by qRT-PCR with a quantification cycle (C q ) valueâ <27, 73% (95% CI, 32-90%) against disease that was qRT-PCR positive but EIA negative, and 62% (95% CI, -20-88%) against disease defined solely by EIA. Results were similar when restricting to disease resulting in at most an ambulatory clinic or emergency department visit. CONCLUSIONS: These results support the effectiveness of rotavirus vaccination in protecting US children from mild to moderate and severe disease. Our findings are also useful to show the effectiveness of rotavirus vaccination against qRT-PCR-defined illness.

AIMS: Postoperative urinary retention (PUR) is a known complication of midurethral sling (MUS) placement. The use of certain perioperative medications may influence the risk of this complication. This study aimed to investigate the association of perioperative medications with urinary retention after MUS. METHODS: This was a retrospective study of women undergoing MUS placement for stress urinary incontinence by a fellowship-trained urologic surgeon between 2015 and 2018, under approval by the Institutional Review Board. Both retropubic and transobturator approaches were included. All patients underwent an active void trial following surgery. Intraoperative medications given by the anesthesia team were retrospectively noted. The Fisher's exact test was used to compare the association of PUR with categorical variables. RESULTS: A total of 82 patients were included, 17 (21%) of whom failed postoperative void trial due to urinary retention. Of 25 patients receiving perioperative scopolamine, 40% failed the postoperative void trial, compared to 12% of patients not receiving scopolamine (p = .048). Groups were then stratified based on scopolamine use due to the observed independent association with PUR. Subgroup analysis revealed a stronger association of postoperative retention with scopolamine in patients undergoing concomitant prolapse surgery. Notably, retention rate and scopolamine use were similar whether patients underwent sling placement alone or in combination with prolapse surgery. Rate of retention was also higher for retropubic versus transobturator slings (36% vs. 9%; p = .005). CONCLUSIONS: Perioperative scopolamine may be associated with an increased risk of postoperative urinary retention following MUS, especially in the setting of a concomitant prolapse surgery.

PURPOSE OF REVIEW: The goal of this paper is to describe the pathophysiology of adult nocturnal enuresis and develop a generalized approach for evaluation and treatment. RECENT FINDINGS: Although nocturnal enuresis (NE) impacts a significant proportion of the adult population, research on this topic remains lacking. In the few existing studies, the management strategy is extrapolated from research on pediatric nocturnal enuresis. Furthermore, treatment approaches highlight the importance of identifying risk factors and contributing pathologies. The modern urologist should understand the complexity of this problem and the variety of techniques to evaluate and treat the adult patient with NE. Adult nocturnal enuresis is multifactorial and may have multiple underlying pathologies. A comprehensive workup requires an understanding of the patient's history and symptomatology and the pathophysiologic processes that can occur. Treatment should first target identifiable etiologies, although a generalized algorithm can then be utilized with behavioral and lifestyle modifications, followed by medical therapy. Future studies will provide a better framework for treating this problem.

BACKGROUND: Best practices for benchmarking the efficacy of simulation-based training programs are not well defined. This study sought to assess feasibility of standardized data collection with multicenter implementation of simulation-based training, and to characterize variability in pediatric trauma resuscitation task completion associated with program characteristics. METHODS: A prospective multicenter observational cohort of resuscitation teams (Nâ¯=â¯30) was used to measure task completion and teamwork during simulated resuscitation of a child with traumatic brain injury. A survey was used to measure center-specific trauma volume and simulation-based training program characteristics among participating centers. RESULTS: No task was consistently performed across all centers. Teamwork skills were associated with faster time to computed tomography notification (râ¯=â¯-0.51, pâ¯<â¯0.01). Notification of the operating room by the resuscitation team occurred more frequently in in situ simulation than in laboratory-based simulation (13/22 versus 0/8, pâ¯<â¯0.01). CONCLUSIONS: Multicenter implementation of a standardized pediatric trauma resuscitation simulation scenario is feasible. Standardized data collection showed wide variability in simulated resuscitation task completion.

Malpractice liability systems exist, in part, to provide compensation for medical malpractice, corrective justice for those injured by it, and to incentivize quality care by punishing substandard care. Defensive medicine is loosely defined as practice based primarily on the fear of litigation rather than on expected patient outcomes. It is largely motivated by a physician's belief that the malpractice system is unfair, slow, and ineffective; these perceptions make malpractice concerns one of the largest physician stressors. A physician's perception of malpractice rarely correlates with the stringency of their state's tort system, overestimates their own risk, and overestimates the cost of defensive practices. While estimates are difficult to make, defensive medicine likely only accounts for 2.8% of total healthcare expenses. The phrase "tort reform" has been frequently used to suggest fixes to the malpractice system and to defensive practices. Safe harbors, clinical practice guidelines, comparative fault reform, reducing plaintiff attorney fees, and apology laws have each been evaluated as potential remedies to defensive practice, although most are unproven and all must be deployed in a state-by-state approach.
RESUMEN
Inter-genogroup reassortant group A rotavirus (RVA) strains possessing a G3 VP7 gene of putative equine origin (EQL-G3) have been detected in humans since 2013. Here we report detection of EQL-G3P[8] RVA strains from the Dominican Republic collected in 2014-16. Whole-gene analysis of RVA in stool specimens revealed 16 EQL-G3P[8] strains, 3 of which appear to have acquired an N1 NSP1 gene from locally-circulating G9P[8] strains and a novel G2P[8] reassortant possessing 7 EQL-G3-associated genes and 3 genes from a locally-circulating G2P[4] strain. Phylogenetic/genetic analyses of VP7 gene sequences revealed nine G3 lineages (I-IX) with newly-assigned lineage IX encompassing all reported human EQL-G3 strains along with the ancestral equine strain. VP1 and NSP2 gene phylogenies suggest that EQL-G3P[8] strains were introduced into the Dominican Republic from Thailand. The emergence of EQL-G3P[8] strains in the Dominican Republic and their reassortment with locally-circulating RVA could have implications for current vaccination strategies.

OBJECTIVE: To describe the relationship between emergency department resource utilization and admission rate at the level of the individual physician. METHODS: Retrospective observational study of physician resource utilization and admitting data at two emergency departments. We calculated observed to expected (O/E) ratios for four measures of resource utilization (intravenous medications and fluids, laboratory testing, plain radiographs, and advanced imaging studies) as well as for admission rate. Expected values reflect adjustment for patient- and time-based variables. We compared O/E ratios for each type of resource utilization to the O/E ratio for admission for each provider. We report degree of correlation (slope of the trendline) and strength of correlation (adjusted R2 value) for each association, as well as categorical results after clustering physicians based on the relationship of resource utilization to admission rate. RESULTS: There were statistically significant positive correlations between resource utilization and physician admission rate. Physicians with lower resource utilization rates were more likely to have lower admission rates, and those with higher resource utilization rates were more likely to have higher admission rates. CONCLUSIONS: In a two-facility study, emergency physician resource utilization and admission rate were positively correlated: those who used more ED resources also tended to admit more patients. These results add to a growing understanding of emergency physician variability.
