Abstract
BACKGROUND AND PURPOSE Blood pressure measurement represents the pressure exerted during heart ejection and filling. There are several ways to measure blood pressure and a valid measure is essential. The purpose of this study was to evaluate the approach to noninvasive blood pressure measurement in children. METHODS Blood pressure measurements were taken using the automatic Phillips MP30 monitor and compared against Welch Allyn blood pressure cuffs with Medline manual sphygmomanometers. RESULTS A total of 492 measurements were taken on 82 subjects, and they demonstrated comparability between automatic and manual devices. CONCLUSIONS Although our study indicated acceptable agreement between automatic and manual blood pressure measurement, it also revealed measurement error remains a concern, with sample size, study protocol, training, and environment all playing a role.

Abstract
AIMS The primary goal of this exploratory study was to examine the association between fear of hypoglycaemia (FOH), hypoglycaemia avoidance behaviours and exercise in active youth with type 1 diabetes (T1D). METHODS 30 youth with T1D who participate in some physical activity (PA), age 15.0 ± 2.4 years, on insulin pump therapy completed the 'Type 1 Diabetes Report of Exercise Practices Survey (T1D-REPS)' and parent and child hypoglycaemia fear surveys (HFS). Twenty-eight participants completed the 3-day PA recall survey. Clinical data and pump downloads were obtained at the time of the survey collection. RESULTS Higher child HFS behaviour and total scores were associated with higher PA levels (P = .003, P = .027), and higher parent HFS behaviour score was associated with higher youth PA levels (P = .031), after adjusting for age, sex, duration of diabetes and BMI. Higher child HFS behaviour score was associated with a higher exercise hypoglycaemia avoidance score on T1D-REPS (r = .38, P = .043). Higher child HFS worry and total scores were associated with higher HbA1c (r = .48, P = .008; r = .46, P = .012). CONCLUSIONS This study demonstrated that, in a generally active cohort of youth with T1D, increased hypoglycaemia avoidance behaviour was associated with higher PA levels. Higher overall FOH scores were associated with PA level, driven by higher behaviour subscale scores, while worry subscales were not correlated with PA level. Those with more FOH intervene more to specifically avoid exercise-associated hypoglycaemia and appear to have worse overall glycaemic control. Thus, improved education is required to improve glycaemic control around exercise while maintaining avoidance of hypoglycaemia.

Abstract
Background Sex steroids such as testosterone and estrogen are necessary for accumulation of bone mass. Transgender youth treated with gonadotropin releasing hormone analogues (GnRHa) to block natal puberty for gender-affirming care are at risk of low bone mineral density (BMD). Previous studies indicate that transfemale patients assigned male at birth (AMAB) have low BMD at baseline, during and after GnRHa treatment despite cross hormone treatment. Transmales assigned female at birth (AFAB), however, have normal BMD at baseline that decreases upon GnRHa treatment, with normalization upon cross hormone therapy. The reason(s) for the low baseline BMD in transfemales is unclear. We aimed to assess the baseline characteristics of transgender youth at a single multidisciplinary gender clinic prior to medical intervention and determine factors associated with BMD. Methods This is a retrospective chart review of patients <19 years old evaluated in the gender clinic. Dual-energy x-ray absorptiometry (DXA) scans were obtained prior to initiation of GnRHa or cross-hormone therapy per Endocrine Society guidelines for the treatment of gender dysphoria. We included patients with DXA scans completed prior to initiation of treatment with GnRHa or cross gender hormones and excluded those with concurrent medical diagnoses that may affect bone density. Data collected were bone mineral density (BMD) Z-scores, anthropometric data, vitamin D and calcium levels, and calcium intake. Multivariable linear regression models were used to assess the impact of vitamin D levels, height Z-score, weight Z-score, and BMI Z-score on subtotal body BMD Z-score, adjusted for sex assigned at birth and age. Results Sixty-four patients were included in our analysis. Of these, 73% were AMAB and 27% AFAB. Gender identity was male in 14%, female in 44%, and non-binary in 42%. Average height Z-score was 0.12, weight Z-score 0.27, and BMI Z-score 0.22 (using sex assigned at birth). Subtotal body BMD Z-scores were greater than zero in 11%, between zero and greater than -2 in 59%, and less than or equal to -2 in 30% of tested patients. AMAB patients had lower BMD Z-scores compared to those AFAB (p<0.05 for all Z-scores). There was a positive association with BMI, height, and weight Z-scores and increasing BMD Z-scores after adjusting for sex assigned at birth and age (p<0.05 for all Z-scores). Patients who consumed <2 servings of calcium per day had lower BMD Z-scores (p<0.05 for all Z-scores). Average vitamin D level was 24 ng/ml (+/- 9.5 SD) with no significant association with BMD Z-scores (adjusted for sex assigned at birth). Conclusions Patients AMAB and patients with calcium intake of < 2 servings/day are associated with lower baseline BMD in a cohort of adolescents seen in a multidisciplinary gender clinic. Height, weight, and BMI are associated linearly with BMD Z-score, following patterns previously described in other populations.

Abstract
BACKGROUND There is evidence that ventilator weaning protocols provide benefit to children receiving mechanical ventilation, but many protocols do not include explicit instructions for decreasing ventilator support from maximal settings. We evaluated care provider opinions on ventilator weaning recommendations made by a computerized decision support tool. METHODS Recommendations for ventilator adjustment were generated using a computerized decision support tool based on the ARDSNet protocol using data from children with acute hypoxemic respiratory failure admitted to the pediatric ICU (PICU). Attending physicians, fellows, nurse practitioners, and respiratory therapists (RTs) caring for these patients answered a brief survey to assess whether recommendations were reasonable and whether the practitioner believed they could be implemented. RESULTS RTs completed 99 surveys and ICU providers completed 96 surveys based on data from 10 patients. RTs and ICU providers found 63.9% and 65.3% of recommendations reasonable, respectively. There were 5 instances of disagreement between RTs and ICU providers. The percent of recommendations that RTs thought could be implemented was 29.9%, whereas this figure for ICU providers was 26.3%, with 4 instances of disagreement. Free-text responses indicated that many RTs and ICU providers were concerned about disrupting current patient stability and low tidal volumes. CONCLUSIONS On initial evaluation, the decision support tool did not appear to be highly acceptable to RTs and ICU providers in our setting because recommendations were rarely implemented. In addition, acceptability did not increase over time as patients generally improved. Most respondents preferred to make no ventilator changes and felt the recommendations were too aggressive. The notable barrier to use was a perception of potential patient instability with weaning.

Abstract
BACKGROUND Handoffs can pose risks to patients. LOCAL PROBLEM Nurses throughout a children's hospital understood patient handoffs differently, resulting in handoff errors (failures) across departments. METHODS Lean principles were used to modify and implement the ISHAPED (Introduction, Story, History, Assessment, Plan, Error Prevention, and Dialogue) tool. INTERVENTIONS The team implemented a modified ISHAPED (m-ISHAPED) tool to align the content shared and the expectations for interdepartmental handoff. RESULTS Improvements were seen in reported patient safety events from 6.84 to 1.57 per 100 patient days (P < .001) and nurse satisfaction from 81.1% to 90.6% (P < .001). CONCLUSIONS A standardized process for interdepartmental nursing handoff was successfully implemented.

Abstract
ObjectivesThis objective was to determine if variations in beef sampling techniques utilized by meat researchers have a significant impact on beef muscle measurements during aging.Materials and MethodsTen beef short loins (IMPS 180) were purchased from a commercial packing plant within 48 h of slaughter. Loins were transported to the NDSU Meat Science laboratory where they were mapped into four sections from most anterior (1) to most posterior (4). Within sections, two, 40-g samples were removed; one sample was vacuum packaged (SMALL-VAC) and the other sample was stored in a wire-closure sealed bag (SMALL-BAG). The remaining whole short loin was vacuum packaged. All samples and whole short loins were stored at 4°C for 10 d. At 10 d, the short loins were sampled again where one, 40-g sample was removed from each mapped section (WHOLE-VAC). Purge loss was measured by weighing each sample prior to packaging treatment and at the end of the 10-d aging period; percentage change in weight was calculated. Troponin-T degradation was determined by western blot. Briefly, protein was extracted in an SDS-phosphate buffer, separated by SDS-PAGE under reducing conditions, and transferred to PVDF membranes. Western analysis was done using an anti-troponin-T antibody (clone JLT 12), and immunoreactive bands (Band 1 = doublet ∼42 to 45 kDa; Band 2 = doublet ∼ 36 to 38 kDa, Band 3 = 30 kDa) were analyzed for differences in density. Sarcomere length was determined using HeNe laser diffraction. Thinly sliced samples (∼50 to 100 mg) were placed in a sucrose-phosphate buffer and subjected to beadmill homogenization. A drop of the homogenate was placed on a glass slide, diffraction patterns were measured, and sarcomere length was calculated. Thiobarbituric acid reactive substances (TBARS) were assessed using a colorimetric assay. Analysis was conducted using Proc Mixed procedure of SAS where storage type, section location, and their interaction were used as fixed effects.ResultsThere was a storage type by section interaction (P = 0.017) that occurred with purge loss. SMALL-VAC samples released more purge than SMALL-BAG from the more posterior samples. Troponin-T Band 1 tended to be less (P = 0.07) in WHOLE-VAC samples compared with SMALL-VAC and SMALL-BAG. There was a storage type by section interaction (P = 0.02) where the most posterior SMALL-BAG samples had greater Band 2. There were no differences (P ≥ 0.25) in Band 3 between treatments. There was no difference (P = 0.29) in sarcomere length due storage type. However, there was a difference (P = 0.01) in sarcomere length between sections, where the shortest sarcomeres were in the center of the strip loin and longest sarcomeres on either end. There was a storage type by section interaction (P = 0.02) for TBARS where concentration was greatest in the most posterior portion of SMALL-BAG compared with WHOLE-VAC.ConclusionCollection of smaller samples for aging studies may not be representative of samples aged in a whole primal cut and may influence research outcomes.

Abstract
ObjectivesThe objective of the study was to determine if a vitamin A deficient diet during beef finishing influences calpain 1 activation during meat aging.Materials and MethodsSixty-four steers of approximately 7 mo of age were subjected to a 14-d acclimation period followed by a 95-d growing period on a low vitamin A diet (1017 IU vitamin A/kg DM) designed to deplete liver vitamin A stores. Steers were assigned to a randomized complete blocked design with a 2 × 2 arrangement of treatments (breed: commercial Angus, n = 32, and purebred Simmental, n = 32; and a Low Vitamin A diet or a control diet). The low Vitamin A (LVA) treatment was a finishing diet with no supplemental vitamin A (723 IU vitamin A/kg DM). The control (CON) treatment was the LVA diet plus supplementation with 2200 IU vitamin A/kg DM for a total of 2923 IU vitamin A/kg DM. Serum retinol concentrations were monitored at the beginning and end of treatment. Upon completion of finishing, steers were slaughtered in two groups at a commercial plant. After fabrication, boneless strip loins (IMPS 180) were collected and transported to NDSU. Samples (approximately 40 g) were collected from the anterior portion of the strip loin on d-2 and d-7 of aging and immediately frozen. Protein was extracted from meat samples in fractionation buffers to yield sarcoplasmic and myofibrillar portions, separated by SDS-PAGE, and transferred to PVDF membranes. Immunoblot analysis was done using anti-desmin (d-2 and d-7) and anti-calpain 1 (d-2) antibodies, and results were visualized and documented. A pooled control was run on all membranes and set to a value of one for normalizing results. All experimental data were analyzed using the Proc Mixed procedure of SAS with breed of steers, dietary treatments, their interaction and slaughter date used as a fixed effect.ResultsCalpain 1 autolysis in the sarcoplasmic protein fraction of the d-2 aged loin samples were not affected by treatment or breed. The myofibrillar protein fraction from Angus loins had greater (P = 0.02) accumulation of the 76 kDa calpain 1 autolysis product than that from the Simmental loins; the myofibrillar fraction of the loins from the LVA treatment tended (P = 0.07) to have more 76 kDa calpain 1 autolysis product than that from the CON. There were not any differences (P > 0.19) in the 80 kDa calpain 1 band or the 78 kDa calpain 1 intermediate autolysis product in the myofibrillar fraction. There was a treatment by breed interaction (P = 0.01) for desmin in the d-7 aged loins where Angus loins from the CON treatment had less accumulation of the 46 kDa band than Angus loins on the LVA treatment and Simmental loins from either treatment.ConclusionVitamin A restriction increased protein proteolysis in Angus but not in Simmental steers. The increased calpain 1 autolysis in Angus vs. Simmental, regardless of Vitamin A treatment, indicates a genetic difference that may be the driver for the increased protein degradation in steers a restricted vitamin A diet.

Abstract
Literature is limited comparing induction immunosuppression in pediatric liver transplant (LTx) recipients. This is a single-center, retrospective cohort study of primary pediatric liver transplants at our center between 2005 and 2016 who received either basiliximab (BSX) or rabbit anti-thymocyte globulin (rATG) induction. Maintenance immunosuppression consisted of tacrolimus ± a corticosteroid taper. Exclusions included receipt of an ABO-incompatible graft, retransplantation, and multi-organ transplantation. Primary outcomes were incidence of treated biopsy-proven acute rejection (tBPAR) and PTLD within the first year and infections within 90 days of LTx. Secondary outcomes included graft and patient survival, time to first tBPAR, and incidence of steroid-resistant rejection (SRR) within the first year post-LTx. A total of 136 patients were included in the final analysis of which 57 patients (42%) received BSX induction. Patients who received rATG induction with or without a 2-week corticosteroid taper experienced significantly more tBPAR compared to those who received BSX induction with a 6-month corticosteroid taper (55.7% vs 33.3%, P = .01). There were no differences in the incidence of PTLD, infections, SRR, graft or patient survival, or time to first tBPAR between the two groups. Induction with rATG either with or without a short corticosteroid taper was associated with significantly more tBPAR in primary pediatric LTx recipients when compared to BSX induction with a prolonged corticosteroid taper in the setting of maintenance immunosuppression with tacrolimus.

Abstract
PURPOSE Practicing and resident pediatricians report inadequate skill in caring for adolescents, despite adolescents comprising roughly one-quarter of most general and subspecialty practices. This study examined the effectiveness of participation in an adolescent medicine rotation at improving pediatric residents' self-perceived skills and confidence across nine key adolescent health domains. We also evaluated the impact of didactic instruction during the rotation. METHODS Resident and recent-graduate participants (n = 34) completed milestone-based self-assessment of their skill and confidence caring for adolescent patients in nine key adolescent health-related domains. This study employed a post-test then retrospective pretest, an educational study design used to minimize response-shift bias whereby participants rate their skill and confidence at the end of the intervention (post-test), and then reflect back to retrospectively rate their preintervention skill (retrospective pretest). Additionally, differences in gains between those who did and did not participate in didactic instruction were evaluated. Didactic instruction was delivered during the adolescent medicine rotation utilizing a flipped-classroom model; participants received standardized preparatory materials and participated in active-learning workshops. RESULTS Participants demonstrated a significant (p ≤ .0001) increase in self-perceived skill levels for all assessed domains after the rotation as compared to before the rotation, whether or not they received didactic instruction. Participation in didactic instruction did not yield significant (p ≤ .05) additional benefit for any of the assessed domains. CONCLUSIONS Participation in an adolescent medicine rotation is of value to pediatric resident trainees and leads to increased self-assessed skill and confidence in caring for youth.

Abstract
PURPOSE This study sought to determine if disparities in insulin pump therapy among youth with type 1 diabetes (T1DM) persist despite recent increases in overall pump use rates. DESIGN AND METHODS All patients aged 6 months-17 years, diagnosed with T1DM, and completed 4+ outpatient diabetes visits at an academically-affiliated pediatric health care center from 2011 to 2016 were identified (n = 2131). Data were collected from existing electronic medical records and a multivariable logistic regression model was used to identify factors associated with insulin pump therapy. RESULTS Findings revealed one novel factor (patients/families whose primary language is Spanish [OR 0.47, p = 0.038] or other non-English languages [OR 0.47, p = 0.028]) and confirmed several previously known factors associated with lower insulin pump use: patients who were older (10-14 years OR 0.38, p < 0.0001; 15+ years OR 0.15, p < 0.0001), male (OR 0.80, p = 0.021), non-Hispanic black (OR 0.59, p = 0.009), American Indian/Alaska Native (OR 0.19, p = 0.023), had either government (OR 0.42, p < 0.0001) or no insurance (OR 0.52, p = 0.004) and poor glycemic control (at least one HbA1c ≥ 8.5%; OR 0.54, p < 0.0001). CONCLUSION Significant disparities in insulin pump use in youth with T1DM persist despite known benefits associated with pump therapy and underlying causes remain unclear. PRACTICE IMPLICATIONS Health care providers should explore barriers to insulin pump therapy, including limited English language proficiency.

Abstract
We sought to compare seroprevalence of protective measles and rubella-specific antibody in mother-infant pairs across two populations: a pre-disease elimination Nepal population with recently introduced rubella vaccine and post-disease elimination U.S. population. Qualitative measles and rubella immunoglobulin G was assessed in maternal serum and cord blood from 258 pairs in Nepal, 2012-2013 and 49 pairs in Seattle, WA, 2014-2015. High rates of protective antibody were observed in both populations. Two hundred and forty-four (95%) pregnant women in Nepal had protective measles antibody versus 44 (92%) in Seattle (P = 0.42). Ninety-six percent of infants in Nepal (N = 246) and Seattle (N = 43) had protective measles antibody (P = 0.75). Ninety-four percentage of pregnant women in Nepal (N = 242) and Seattle (N = 45) had protective rubella antibody (P = 0.23). Two hundred and thirty-eight (93%) infants in Nepal had protective rubella antibody versus 44 (98%) in Seattle (P = 0.12). Continued surveillance will be necessary to ensure protective immunity, inform progress toward disease elimination in Nepal and avoid reemergence in the United States.

Abstract
PURPOSE This study examines the use of phone referral information to predict Emergency Severity Index triage levels as a proxy to anticipate emergency department nursing resource allocation in a pediatric hospital. It also assesses the relationship between these pre-arrival triage levels and hospital admission. DESIGN AND METHODS Emergency nurses with specialized training used standardized phone referral information to assign triage levels to 481 patients before their arrival. Upon patient arrival, independent triage levels were assigned. The two levels were then compared and patient disposition was collected. Descriptive statistics and Cohen's kappa were used to assess agreement between the two emergency severity index levels. RESULTS Moderate agreement was found between the pre-arrival and arrival triage levels. The majority of patients (71.3%) with a pre-arrival triage level of 1 or 2 (the most acute levels) were admitted to the hospital. These patients were also more likely to be admitted to the intensive care unit than were patients with a pre-arrival triage level≥3. CONCLUSIONS AND PRACTICE IMPLICATIONS The ability to predict triage levels for incoming patients could give the emergency department charge nurse the ability to plan ahead so that appropriate nursing staffing is available upon arrival. The knowledge that patients assigned a pre-arrival triage level of 1 or 2 are more likely to be admitted gives the emergency department the ability to plan for bed placement and inpatient nursing resources earlier, potentially resulting in decreased emergency department length of stay. More study on these potential benefits is needed.

Abstract
Graft-versus-host disease (GVHD) is an important cause of morbidity and mortality after allogeneic hematopoietic cell transplantation (HCT). Many studies have suggested that human herpesvirus-6B (HHV-6B) plays a role in acute GVHD (aGVHD) after HCT. Our objective was to systematically summarize and analyze evidence regarding HHV-6B reactivation and development of aGVHD. PubMed and EMBASE databases were searched using terms for HHV-6, HCT, and aGVHD, yielding 865 unique results. Case reports, reviews, articles focusing on inherited chromosomally integrated HHV-6, poster presentations, and articles not published in English were excluded. The remaining 467 articles were reviewed for the following requirements: a statistical analysis of HHV-6B reactivation and a GVHD was described, HHV-6B reactivation was defined by PCR, and blood (plasma, serum, or peripheral blood mononuclear cells) was used for HHV-6B PCR. Data were abstracted from publications that met these criteria (n = 33). Publications were assigned to 1 of 3 groups: (1) HHV-6B reactivation was analyzed as a time-dependent risk factor for subsequent aGVHD (n = 14), (2) aGVHD was analyzed as a time-dependent risk factor for subsequent HHV-6B reactivation (n = 1), and (3) analysis without temporal specification (n = 18). A statistically significant association (P < .05) between HHV-6B reactivation and aGVHD was observed in 10 of 14 studies (71%) in group 1, 0 of 1 study (0%) in Group 2, and 8 of 18 studies (44.4%) in Group 3. Of the 14 studies that analyzed HHV-6B as a risk factor for subsequent aGVHD, 11 performed a multivariate analysis and reported a hazard ratio, which reached statistical significance in 9 of these s tudies. Meta-analysis of these 11 studies demonstrated a statistically significant association between HHV-6B and subsequent grades II to IV aGVHD (hazard ratio, 2.65; 95% confidence interval, 1.89 to 3.72; P < .001).HHV-6B reactivation is associated with aGVHD, and when studies have a temporal component to their design, HHV-6B reactivation is associated with subsequent aGVHD. Further research is needed to investigate whether antiviral prophylaxis reduces incidence or severity of aGVHD.

Abstract
OBJECTIVES Postoperative calcium management is challenging following pediatric thyroidectomy given potential limitations in self-reporting symptoms and compliance with phlebotomy. A protocol was created at our tertiary children's institution utilizing intraoperative parathyroid hormone (PTH) levels to guide electrolyte management during hospitalization. The objective of this study was to determine the effect of a new thyroidectomy postoperative management protocol on two primary outcomes: (1) the number of postoperative calcium blood draws and (2) the length of hospital stay. STUDY DESIGN Institutional review board approved retrospective study (2010-2016). METHODS Consecutive pediatric total thyroidectomy and completion thyroidectomy ± neck dissection cases from 1/1/2010 through 8/5/2016 at a single tertiary children's institution were retrospectively reviewed before and after initiation of a new management protocol. All cases after 2/1/2014 comprised the experimental group (post-protocol implementation). The pre-protocol control group consisted of cases prior to 2/1/2014. Multivariable linear and Poisson regression models were used to compare the control and experimental groups for outcome measure of number of calcium lab draws and hospital length of stay. RESULTS 53 patients were included (n = 23, control group; n = 30 experimental group). The median age was 15 years. 41 patients (77.4%) were female. Postoperative calcium draws decreased from a mean of 5.2 to 3.6 per day post-protocol implementation (Rate Ratio = 0.70, p < .001), adjusting for covariates. The mean number of total inpatient calcium draws before protocol initiation was 13.3 (±13.20) compared to 7.2 (±4.25) in the post-protocol implementation group. Length of stay was 2.1 days in the control group and 1.8 days post-protocol implementation (p = .29). Patients who underwent concurrent neck dissection had a longer mean length of stay of 2.32 days compared to 1.66 days in those patients who did not undergo a neck dissection (p = .02). Hypocalcemia was also associated with a longer mean length of stay of 2.41 days compared to 1.60 days in patients who did not develop hypocalcemia (p < .01). CONCLUSIONS The number of calcium blood draws was significantly reduced after introduction of a standardized protocol based on intraoperative PTH levels. The hospital length of stay did not change. Adoption of a standardized postoperative protocol based on intraoperative PTH levels may reduce the number of blood draws in children undergoing thyroidectomy.

Am J Otolaryngol 2018; 39:56-64.

Abstract
SIGNIFICANCE Current grading systems may not allow clinicians to reliably document and communicate adenotonsillar size in the clinical setting. A validated endoscopic grading system may be useful for reporting tonsillar size in future clinical outcome studies. This is especially important as tonsillar enlargement is the cause of a substantial health care burden on children. OBJECTIVE To propose and validate an easy-to-use flexible fiberoptic endoscopic grading system that provides physicians with a more accurate sense of the three-dimensional relationship of the tonsillar fossa to the upper-airway. METHODS 50 consecutive pediatric patients were prospectively recruited between February 2015 and February 2016 at a pediatric otolaryngology outpatient clinic. The patients had no major craniofacial abnormalities and were aged 1 to 16years. Each patient had data regarding BMI, Friedman palate position, OSA-18 survey results collected. For each child, digital video clips of fiberoptic nasopharyngeal, oropharyngeal and laryngeal exams were presented to 2 examiners. Examiners were asked to independently use the proposed Endoscopic tonsillar grading system, the Brodsky tonsillar grading scale, the Modified Brodsky tonsillar grading scale with a tongue depressor, and the Parikh adenoid grading system to rate adenotonsillar hypertrophy. Cohen's Kappa and weighted Kappa scores were used to assess interrater reliability for each of the four grading scales. The Spearman correlation was used to test the associations between each scale and OSA-18 scores, as well as Body Mass Index (BMI). RESULTS 50 pediatric patients were included in this study (mean age 6.1years, range of 1year to 16years). The average BMI was 20. The average OSA-18 score was 61.7. The average Friedman palate position score was 1.34. Twelve percent of the patients had a Friedman palate position score≥3, which made traditional Brodsky grading of their tonsils impossible without a tongue depressor. All four scales showed strong agreement between the two raters. The weighted Kappa was 0.83 for the Modified Brodsky scale, 0.89 for the Brodsky scale, 0.94 for the Parikh scale to 0.98 for the Endoscopic scale (almost perfect agreement). The Endoscopic scale showed the most consistent agreement between the raters during the study. There was a moderate association between the Parikh adenoid grading system with OSA-18 scores (Spearman's ρ=0.58, p<0.001) compared to a low association of the tonsillar grading systems with OSA- 18 scores. None of the scales correlated with patient BMI. CONCLUSIONS The proposed Endoscopic tonsillar grading system is as reliable of a method of grading tonsillar size as conventional grading systems. It offers the advantage of allowing for critical evaluation of the tonsils without any anatomic distortion which may occur with the use of a tongue blade. This new validated endoscopic grading system provides a tool for communicating the degree of airway obstruction at the level of the oropharynx regardless of Friedman palate position and may be used in future outcomes projects.

Abstract
BACKGROUND Patients in intensive care units are likely to have limited mobility owing to hemodynamic instability and activity orders for bed rest. Bed rest is indicated because of the severity of the disease process, which often involves intubation, sedation, paralysis, surgical procedures, poor nutrition, low flow states, and poor circulation. These patients are predisposed to the development and/or the progression of pressure ulcers not only because of their underlying diseases, but also because of limited mobility and deconditioned states of health. OBJECTIVE To assess whether treating high-risk patients with a prophylactic sacral dressing decreases the incidence of unit-acquired sacral pressure ulcers. METHODS An evidence-based tool for identifying patients at high risk for pressure ulcers was used in 3 intensive care units at an urban tertiary care hospital and academic medical center. Those patients deemed at high risk had a prophylactic sacral dressing applied. Incidence rates were collected and compared for the 7 months preceding use of the dressings and for 7 months during the trial period when the dressing was used. RESULTS After the sacral dressing began being used, the number of unit-acquired sacral pressure ulcers decreased by 3.4 to 7.6 per 1000 patient days depending on the unit. CONCLUSIONS A prophylactic sacral dressing may help prevent unit-acquired sacral pressure ulcers. Implementation of an involved care team with heightened awareness and increased education along with a prophylactic sacral dressing in patients deemed high risk for skin breakdown are all essential for success.
