Impact of Ketorolac on Reoperation for Hemorrhage After Pediatric Tonsillectomy: A Single-Center Retrospective Propensity-Matched Study.

OBJECTIVE: To determine if perioperative ketorolac is associated with an increased rate of reoperation for hemorrhage after pediatric tonsillectomy at 30 days and 48 hours. STUDY DESIGN: Single-center retrospective propensity-matched study. SETTING: Quaternary pediatric hospital and ambulatory surgery center. METHODS: Patients less than 18 years old undergoing tonsillectomy or adenotonsillectomy between January 1, 2015 and October 1, 2020 were included. Hemorrhage rates between exposed (K+) and unexposed (K-) patients were calculated for the total cohort and a 1:1 propensity-matched cohort. Additional analyses included: multivariable logistic regression, subgroup analysis of ASA 1 and 2 patients, subgroup analysis comparing children with teenagers. RESULTS: There were 5873 patients (42.1% K+) in the full cohort and 4694 patients in the propensity-matched cohort. Reoperation for hemorrhage within 30 days occurred in 1.9% of K+ patients and 1.6% of K- patients (P = 0.455) in the full cohort and 1.9% of K+ patients and 1.7% of K- patients (odds ratio [OR] 1.10, 95% confidence interval [CI] 0.72-1.69, P = 0.662) in the propensity-matched cohort. Reoperation within 48 hours occurred in 0.65% of K+ patients and 0.53% of K- patients (P = 0.679) in the full cohort and 0.68% of K+ patients and 0.51% of K- patients (OR 1.33, 95% CI 0.63-2.81, P = 0.451) in the propensity-matched cohort. There was no association between perioperative ketorolac administration and reoperation for hemorrhage in any of the other analyses. CONCLUSION: Ketorolac at end of surgery should be considered as part of the nonopioid analgesic regimen for pediatric tonsillectomy.

Comparing outcomes of percutaneous cholecystostomy drain placement between patients within and outside of Tokyo guidelines diagnostic criteria for acute cholecystitis.

OBJECTIVE: To compare outcomes following percutaneous cholecystostomy drain placement based on presence or absence of Tokyo Guidelines diagnostic criteria for acute cholecystitis. METHODS: Chart review was performed to identify the presence or absence of Tokyo Guidelines diagnostic criteria for acute cholecystitis in 146 patients who underwent percutaneous cholecystostomy between 2012 and 2015. Those who met criteria were compared to those who did not in terms of demographics, laboratory values, drain indwelling time, treatment response, eventual surgical management, and 30-day mortality. RESULTS: 94 patients (64%) met Tokyo Guidelines diagnostic criteria, while 52 did not (36%). Patients within criteria had a shorter mean length of stay (13.5 days vs 18.9 days), were more likely to have a positive gallbladder fluid culture (64.5% vs 28.6%), demonstrated greater response to treatment (87.2% vs 32.7%), and had lower 30-day mortality (6.4% vs 37.8%). There was no significant difference in terms of ICU requirement (38.3% vs 38.9%), mean drain indwelling time (58.8 days vs 65.3 days), eventual laparoscopic cholecystectomy (40.4% vs 25.0%), or open cholecystectomy performed (9.5% vs 9.6%). CONCLUSION: Patients outside of Tokyo Guidelines diagnostic criteria for acute cholecystitis were less likely to respond to treatment with percutaneous cholecystostomy and had worse outcomes. Further research may be indicated to better define the indications for percutaneous cholecystostomy placement in this group.

Recruitment in Surgery and Interventional Radiology: Factors in Female Trainees' Specialty Decisions.

OBJECTIVE: This study aims to identify factors influencing female medical students' decision-making about specialties, specifically surgery and interventional radiology (IR), in an effort to inform future recruitment and professional development strategies. DESIGN: An electronic survey was created to assess both qualitative and quantitative data. SETTING: The survey was sent prior to a symposium for trainees interested in pursuing IR or surgery, held at University of Chicago (Chicago, IL) in February 2019. PARTICIPANTS: The 90 female trainees who registered were sent the survey, and 48 (53%) responded voluntarily. RESULTS: All respondents were female, 46% planned to pursue surgery or IR. Students pursuing surgery/IR were less concerned about being valued by their colleagues (p = 0.0073), being in charge of patients' lives (p = 0.0017), radiation exposure (p = 0.0171), chemical exposure (p = 0.0223), emotional stress (p = 0.0244), or shift work (p = 0.0045), compared to the nonsurgery/IR students. No differences were found in ranking of motivating factors, personal strengths or weaknesses, deciding factors, areas for seeking mentorship, or gender diversity. Top motivations among all respondents were intellectual rigor of medicine and becoming a mentor, while concerns were personal physical health, managing a career, pay equity, and gender-based biases. Students most often sought mentors and clerkship experience for making specialty decisions. They reported greatest strengths in empathy and resilience, and weaknesses in negotiating and public speaking. CONCLUSIONS: Female medical students planning to pursue surgery/IR expressed greater confidence in their contributions to patient care and lower concerns about workplace hazards. Regardless of specialty intent, female students shared scholarship motivations for a career in medicine, valued the role of mentorship, and expressed persistent concerns about gender discrimination, personal health, and skills-based weaknesses. Identifying factors influential in career decision-making is important in order to recruit and retain a more gender-diverse physician workforce.

Accuracy of Clinicians' Ability to Predict the Need for Intensive Care Unit Readmission.

Rationale: Determining when an intensive care unit (ICU) patient is ready for discharge to the ward is a complex daily challenge for any ICU care team. Patients who experience unplanned readmissions to the ICU have increased mortality, length of stay, and cost compared with those not readmitted during their hospital stay. The accuracy of clinician prediction for ICU readmission is unknown.Objectives: To determine the accuracy of ICU physicians and nurses for predicting ICU readmissionsMethods: We conducted a prospective study in the medical ICU of an academic hospital from October 2015 to September 2017. After daily rounding for patients being transferred to the ward, ICU clinicians (nurses, residents, fellows, and attendings) were asked to report the likelihood of readmission within 48 hours (using a 1-10 scale, with 10 being "extremely likely"). The accuracy of the clinician prediction score (1-10) was assessed for all clinicians and by clinician type using sensitivity, specificity, and area under the curve (AUC) for the receiver operating characteristic curve for predicting the primary outcome, which was ICU readmission within 48 hours of ICU discharge.Results: A total of 2,833 surveys was collected for 938 ICU-to-ward transfers, of which 40 (4%) were readmitted to the ICU within 48 hours of transfer. The median clinician likelihood of readmission score was 3 (interquartile range, 2-4). When physician and nurse likelihood scores were combined, the median clinician likelihood score had an AUC of 0.70 (95% confidence interval [CI], 0.62-0.78) for predicting ICU readmission within 48 hours. Nurses were significantly more accurate than interns at predicting 48-hour ICU readmission (AUC, 0.73 [95% CI, 0.64-0.82] vs. AUC, 0.60 [95% CI, 0.49-0.71]; P = 0.03). All other pairwise comparisons were not significantly different for predicting ICU readmission within 48 hours (P > 0.05 for all comparisons).Conclusions: We found that all clinicians surveyed in our ICU, regardless of the level of experience or clinician type, had only fair accuracy for predicting ICU readmission. Further research is needed to determine if clinical decision support tools would provide prognostic value above and beyond clinical judgment for determining who is ready for ICU discharge.

11C-DPA-713 has much greater specific binding to translocator protein 18 kDa (TSPO) in human brain than 11C-( R)-PK11195.

Positron emission tomography (PET) radioligands for translocator protein 18 kDa (TSPO) are widely used to measure neuroinflammation, but controversy exists whether second-generation radioligands are superior to the prototypical agent 11C-( R)-PK11195 in human imaging. This study sought to quantitatively measure the "signal to background" ratio (assessed as binding potential ( BPND)) of 11C-( R)-PK11195 compared to one of the most promising second-generation radioligands, 11C-DPA-713. Healthy subjects had dynamic PET scans and arterial blood measurements of radioligand after injection of either 11C-( R)-PK11195 (16 subjects) or 11C-DPA-713 (22 subjects). To measure the amount of specific binding, a subset of these subjects was scanned after administration of the TSPO blocking drug XBD173 (30-90 mg PO). 11C-DPA-713 showed a significant sensitivity to genotype in brain, whereas 11C-( R)-PK11195 did not. Lassen occupancy plot analysis revealed that the specific binding of 11C-DPA-713 was much greater than that of 11C-( R)-PK11195. The BPND in high-affinity binders was about 10-fold higher for 11C-DPA-713 (7.3) than for 11C-( R)-PK11195 (0.75). Although the high specific binding of 11C-DPA-713 suggests it is an ideal ligand to measure TSPO, we also found that its distribution volume increased over time, consistent with the accumulation of radiometabolites in brain.
