Objective: The study aimed to evaluate the validity of transcutaneous bilirubin (TcB) measurements at three sites in premature infants born at 23 0/7 to 34 6/7 weeks' gestational age (GA) compared with total serum bilirubin (TSB) measurements., Study Design: A prospective study was conducted at Banner - University Medical Center Phoenix, where informed consent was obtained from the infant's parent or legally authorized representative. Cohort A was comprised of infants 23 0/7 to 28 6/7 weeks' GA and Cohort B contained subjects 29 0/7 to 34 6/7 weeks' GA. Baseline TSB measurements were collected at approximately 24 hours of life, as the standard of care and the TcB measurements were obtained from the sternum, interscapular, and buttock areas at approximately ± 30 minutes from collection of the TSB. Statistical analysis of measurements including sensitivity, specificity, positive, and negative predictive values, and the area under the receiver operator characteristic curve (AUROC) were performed., Results: A total of 166 infants were included in the study population. Cohort A consisted of 41 subjects and Cohort B contained 125 subjects. The results showed that baseline TcB measurements from the interscapular area were the most sensitive and specific with TSB levels >5.0 mg/dL in Cohort A. Baseline TcB measurements from the sternum demonstrated greatest sensitivity and specificity when the TSB level was >8.0 mg/dL in Cohort B. In general, each of the three sites in both cohorts demonstrated excellent AUROCs and negative predictive values., Conclusion: The use of a TcB meter in preterm infants can be a reliable noninvasive screening tool for hyperbilirubinemia, and it may be beneficial in decreasing painful stimuli and iatrogenic blood loss when used as an adjunct to TSB monitoring., Key Points: · Interscapular TcB is sensitive/specific in 23 to 29 weeks' GA.. · Sternal TcB is sensitive/specific in 29 to 35 weeks' GA.. · TcB readings are reliable in preterm infants.. · TcB is reliable when serum bilirubin is >5.0 mg/dL.., Competing Interests: None declared., (Thieme.

Background: To address the opioid epidemic, physicians are encouraged to identify means of reducing patient opioid exposure. Electronic medical records (EMRs) often include default order sets with automated orders for opioid medications, which may influence how much opioids physicians prescribe. We sought to evaluate the impact of de-selecting an automated order for oxycodone-acetaminophen from an EMR order set for postpartum vaginal deliveries on inpatient opioid exposure by comparing the proportion of patients who received an opioid after an uncomplicated vaginal delivery before and after the EMR change. As secondary outcomes, the impact on average total morphine milligram equivalents (MMEs) and discharge opioid prescriptions was investigated. Materials and Methods: A quality improvement study was conducted through retrospective chart review of uncomplicated vaginal deliveries for the four quarters before and after the EMR order set change occurred. The total proportion of patients who received an opioid in the postpartum period was then determined for the preexposure and postexposure groups. The total average MME consumed for patients who received an opioid in each group was determined and the total proportion of patients who received an opioid prescription at discharge was compared. Results: A total of 5826 records of uncomplicated vaginal deliveries met the criteria for analysis. In the preintervention group, 32.9% of patients received an opioid postpartum, compared to 12.5% of patients in the postintervention group, representing a decrease of 62.0% ( p  < 0.001). Of those who received opioids, the preintervention mean total opioid consumption was 28.4 MME (±27.6) compared to 33.6 MME (±46.4) postintervention, and there was no significant difference in median total opioid consumption: 22.5 MME (interquartile range [IQR]: 7.5-47.5) preintervention compared with 20.8 MME (IQR: 7.5-45.0) postintervention ( p  = 0.902). No significant difference was found with discharge opioid prescriptions between the two groups. Conclusion: Order sets within EMR systems appear to have a significant influence on physician prescribing behaviors and removing these automated orders for opioids should be considered.

Background: The Gaze Stabilization Test (GST) assesses vestibulo-ocular reflex (VOR) function by determining the maximum head velocity at which an individual can accurately perceive a fixed-size visual target. There is limited information about gaze stability performance in youth athletes., Objective: The purpose of this study is to describe baseline performance of athletes ages 17 years and under on a computerized GST and explore the influence of demographic characteristics on performance., Methods: Baseline GST and demographic data were acquired via retrospective chart review., Results: The sample included 106 athletes aged 8 to 17 years (mean 13.9 years±1.79; 78% male). The median values for baseline GST function were 180 (IQR: 150-210) degrees per second (d/sec) in the leftward direction, and 190 d/sec (IQR: 160-220) in the rightward direction. There were no significant effects of sex/gender or concussion history on GST performance., Conclusions: The GST is one of many tools available for clinicians to use in a multi-modal approach to concussion management. Understanding how healthy young athletes perform can assist clinicians in determining vestibular impairment, formulating the exercise prescription, and estimating physiologic recovery.

Purpose: To determine whether tidal volume/predicted body weight (TV/PBW) or driving pressure (DP) are associated with mortality in a heterogeneous population of hypoxic mechanically ventilated patients., Methods: A retrospective cohort study involving 18 intensive care units included consecutive patients ≥18 years old, receiving mechanical ventilation for ≥3 days, with a PaO2/FiO2 ratio ≤300 mmHg, whether or not they met full criteria for ARDS. The main outcome was hospital mortality. Multiple logistic regression (MLR) incorporated TV/PBW, DP, and potential confounders including age, APACHE IVa® predicted hospital mortality, respiratory system compliance (CRS), and PaO2/FiO2. Predetermined strata of TV/PBW were compared using MLR., Results: Our cohort comprised 5,167 patients with mean age 61.9 years, APACHE IVa® score 79.3, PaO2/FiO2 166 mmHg and CRS 40.5 ml/cm H2O. Regression analysis revealed that patients receiving DP one standard deviation above the mean or higher (≥19 cmH20) had an adjusted odds ratio for mortality (ORmort) = 1.10 (95% CI: 1.06-1.13, p = 0.009). Regression analysis showed a U-shaped relationship between strata of TV/PBW and adjusted mortality. Using TV/PBW 4-6 ml/kg as the referent group, patients receiving >10 ml/kg had similar adjusted ORmort, but those receiving 6-7, 7-8 and 8-10 ml/kg had lower adjusted ORmort (95%CI) of 0.81 (0.65-1.00), 0.78 (0.63-0.97) and 0.80 0.67-1.01) respectively. The adjusted ORmort in patients receiving 4-6 ml/kg was 1.26 (95%CI: 1.04-1.52) compared to patients receiving 6-10 ml/kg., Conclusions: Driving pressures ≥19 cmH2O were associated with increased adjusted mortality. TV/PBW 4-6ml/kg were used in less than 15% of patients and associated with increased adjusted mortality compared to TV/PBW 6-10 ml/kg used in 82% of patients. Prospective clinical trials are needed to prove whether limiting DP or the use of TV/PBW 6-10 ml/kg versus 4-6 ml/kg benefits mortality., Competing Interests: The authors have declared that no competing interests exist.

Context.—: Automated analyzers have advanced the field of clinical hematology, mandating updated complete blood count (CBC) reference intervals (RIs) to be clinically useful. Contemporary newborn CBC RI publications are mostly retrospective, which some authors have cited as one of their cardinal limitations and recommended future prospective studies., Objective.—: To prospectively establish accurate hematologic RIs for normal healthy term newborns at 24 hours of life given the limitations of the current medical literature., Design.—: This prospective study was conducted at an academic tertiary care center, and hematology samples were collected from 120 participants deemed to be normal healthy term newborns. Distributions were assessed for normality and tested for outliers. Reference intervals were values between the 2.5th percentile and 97.5th percentile., Results.—: The novel RIs obtained for this study population are as follows: absolute immature granulocyte count, 80/μL to 1700/μL; immature granulocyte percentage, 0.6% to 6.1%; reticulocyte hemoglobin equivalent, 31.7 to 38.4 pg; immature reticulocyte fraction, 35.9% to 52.8%; immature platelet count, 4.73 × 103/μL to 19.72 × 103/μL; and immature platelet fraction, 1.7% to 9.8%., Conclusions.—: This prospective study has defined hematologic RIs for this newborn population, including new advanced clinical parameters from the Sysmex XN-1000 Automated Hematology Analyzer. These RIs are proposed as the new standard and can serve as a strong foundation for continued research to further explore their value in diagnosing and managing morbidities such as sepsis, anemia, and thrombocytopenia., (© 2021 College of American Pathologists.)

Background: Cesarean delivery is the most common major surgical procedure performed in the United States. Women with class III obesity have an increased risk of cesarean delivery and have wound complication rates higher than healthy body mass index counterparts. Available evidence regarding optimal wound closure is lacking specific to the population of women with class III obesity despite a known increased rate of wound complications., Objective: This study aimed to compare rates of postoperative wound complications among women with class III obesity (body mass index of ≥40 kg/m 2 ) undergoing cesarean delivery with skin closure by either subcuticular suture or surgical staples., Study Design: Patients were randomly assigned to skin closure by nonabsorbable stainless steel surgical staples or subcuticular suture of the surgeon's choice at the time of cesarean delivery at 2 university hospitals. Randomization was stratified for scheduled vs unscheduled cesarean delivery and for the 2 study sites. The primary outcome was the rate of any documented wound complication during the first 6 weeks after delivery. Any predictors of the composite outcome that in univariate analysis had a P<.20 were entered into a forward logistic regression. Sample size was calculated based on published literature and estimating the rate of wound complications within 6 weeks of follow-up at 20% with staples and 10% with sutures. For a power of 0.80 with a 2-tailed of 0.05, a total of 199 participants per group were required., Results: From September 2015 to May 2019, 232 women were randomized to staples (n=117) or sutures (n=115). Nearing the planned interim analysis, enrollment in the study was concluded administratively owing to low enrollment. With loss to follow-up and exclusions, a total of 90 women were analyzed in each group. In the suture group, one-third was closed with braided suture and two-thirds were closed with monofilament suture. Median staple removal was 5 days postoperatively. Fewer composite wound complications were noted in the surgical staples group than the subcuticular suture group (20.0% vs 27.6%), although this difference was not statistically significant (P≥.5). The rate of surgical site infection was significantly lower in the staples group (10.5% vs 22.7%; P=.041). In the multiple logistic regression, the 3 significant independent predictors of the outcome were body mass index (odds ratio, 1.08; P=.004), scheduled vs unscheduled cesarean delivery (odds ratio, 0.40; P=.018), and study site (odds ratio, 0.36; P=.028)., Conclusion: Surgical staples or subcuticular suture for skin closure at the time of cesarean delivery in women with a body mass index of ≥40 kg/m 2 resulted in similar composite wound complication rates; however, lower cesarean wound infection rates were noted among wounds closed with staples., (Copyright © 2020 Elsevier Inc.

A universal vaccine against influenza would ideally generate protective immune responses that are not only broadly reactive against multiple influenza strains but also long-lasting. Because long-term serum antibody levels are maintained by bone marrow plasma cells (BMPCs), we investigated the production and maintenance of these cells after influenza vaccination. We found increased numbers of influenza-specific BMPCs 4 weeks after immunization with the seasonal inactivated influenza vaccine, but numbers returned to near their prevaccination levels after 1 year. This decline was driven by the loss of BMPCs induced by the vaccine, whereas preexisting BMPCs were maintained. Our results suggest that most BMPCs generated by influenza vaccination in adults are short-lived. Designing strategies to enhance their persistence will be a key challenge for the next generation of influenza vaccines., (Copyright © 2020 The Authors, some rights reserved; exclusive licensee American Association for the Advancement of Science.

Study Objective: To compare obstetric and surgical outcomes of transabdominal cerclage (TAC) via laparotomy (TAC-LAP) versus robotic-assisted (TAC-RA) approaches., Design: Retrospective cohort study., Setting: An academic medical center., Patients: Sixty-nine women with acquired or congenital cervical insufficiency., Interventions: All women underwent TAC either by laparotomy or robotic-assisted approaches by 2 primary surgeons between January 2003 and July 2018. Women with a preconceptional TAC without a subsequent pregnancy were excluded., Measurements and Main Results: A total of 69 women met inclusion criteria in the 15-year study period with 40 in the historical TAC-LAP group and 29 in the TAC-RA group. Gestational age at delivery was similar in the 2 groups (36 weeks 3 days vs 37 weeks; median difference -1 day, 95% confidence interval [CI] -6 to 2, p = .36). There were no differences in birth weight, Apgar scores, neonatal intensive care unit admission, or neonatal survival. Estimated blood loss and length of stay were significantly greater in the TAC-LAP group (50 mL vs 20 mL; median difference 25, 95% CI 5-40, p = .007 and 76 hours vs 3 hours; median difference 71, 95% CI 65-75, p <.001, respectively). Operative time was significantly shorter in the TAC-LAP group (65 minutes vs 132 minutes; median difference -64.7, 95% CI -79 to -49, p <.001). There was one intra-operative complication and 4 minor postoperative complications in the TAC-LAP group and none observed in the TAC-RA group. All outcomes were similar when comparing postconceptional TAC alone, except there was no longer a difference in blood loss. When comparing pre- versus postconceptional robotic TAC, there were no differences in surgical outcomes., Conclusion: Robotic TAC has similar favorable obstetric outcomes to traditional laparotomy and is associated with reduced blood loss and shorter hospital stays. Despite longer operative times, the robotic group did not experience any intra-operative or postoperative complications, which speaks to the benefits of this minimally invasive approach to TAC., (Copyright © 2019 AAGL.

Background and Objectives: The program director (PD) position is challenging. PDs are faced with many competing priorities and risk of burnout. Short PD tenure may contribute to training program challenges. The tenure of family medicine residency directors has not been rigorously studied. Our objective was to study family medicine program director tenure and change in tenure over time, and compare these to available Accreditation Council for Graduate Medical Education (ACGME) data., Methods: We analyzed the 11 Council of Academic Family Medicine Educational Research Alliance PD surveys from 2011 through 2017. We calculated mean and median responses to the question "How long have you been program director at your current program?" We compared these results to data from the ACGME Data Resource Book for all specialty programs., Results: Of 2,577 responses in 11 PD surveys over 7 years, mean family medicine PD tenure was 6.5 years and median tenure was 4.5 years. Tenure did not change significantly from 2011-2017, and 30.5% of PDs have been in their position 0, 1, or 2 years. The right skew in our data (ie, median substantially less than mean), is similar to that seen in other specialties., Conclusions: Mean family medicine PD tenure is 6.5 years and median tenure is 4.5 years. The short tenure and large number of new PDs annually may impact program quality and suggests more resources and support may be needed for PDs new in their position.
