Due to the short duration of the perioperative period, the interaction in this setting is limited and providers may not have the time to develop a rapport with the patient. It is imperative that staff are trained to address the patient and family in a culturally competent manner.Methods: We undertook surveys before and after a 2 part educational series among the pediatric perioperative staff to understand the impact of providing education and cultural competency training regarding caring for patients who identify as LGBTQ. Providers self-reported their knowledge and comfort on a 1–5 point scale (5 being most knowledgeable or comfortable) in 6 domains of caring for LGBTQ patients. Objective knowledge of LGBTQ issues was assessed using 7 questions based on lecture material. On objective assessment, knowledge of LGBTQ issues improved after cultural competency training.Results: The analysis included 90 responses. Before training, median ratings of knowledge and comfort were 3 or 4 out of a maximum of 5 for each domain. The pre-training median score on the 7-item test of LGBTQ cultural competency was 5 (IQR: 4, 6). After training, knowledge and comfort self-ratings did not improve, but the score on the objective knowledge test increased to a median of 6 (IQR: 4, 7; p=0.011) of 7 possible points.Discussion: Anesthesia providers participating in LGBTQ cultural competency training self-reported high levels of knowledge and comfort with providing care to LGBTQ patients even before formal training was provided. On objective assessment, knowledge of LGBTQ issues improved after cultural competency training.Keywords: LGBTQ, health, concerns, competency, training, attitude

At 5 mins intervals, IBP was measured using a fluid-coupled pressure transducer and NIBP was measured with two oscillometers with appropriately sized cuffs placed on the upper arm and lower leg, for 10 readings per patient.Results: The study enrolled 18 boys and 12 girls, ranging in age from 0 to 8 years. Across 300 data points, the absolute difference between the arm and invasive mean arterial pressure (MAP) measurements was 7±7 mmHg (range: 0–52 mmHg). The absolute difference between the leg and invasive MAP measurements was 8±8 mmHg (range: 0–52 mmHg). Although both non-invasive measurement sites demonstrated frequent deviation from invasive measurement, large deviations were more common when BP was measured at the leg (81 of 298 observations (27%) deviating by >10 mmHg) compared to the arm (60 of 300 observations (20%) deviating by >10 mmHg).Conclusion: The frequency of clinically significant NIBP deviation in children under general anesthesia supports the importance of IBP monitoring when hemodynamic fluctuations are likely and would be particularly detrimental. NIBP measured at the lower leg is more likely to result in clinically significant deviation from invasively measured MAP than NIBP values obtained from an upper arm.Keywords: invasive blood pressure, non-invasive blood pressure, blood pressure cuff

This practice may reduce unplanned revisits following hospital discharge.Study design: Retrospective cohort study.Subjects: Children from the PHIS database.Methods: T&A performed in children during the years 2007–2015 were identified in the Pediatric Health Information System. The primary outcome was 7-day, all-cause readmission or emergency department (ED) revisit. Secondary analysis examined specific revisit types and 30-day revisits. The primary exposure was each institution’s annual rate of overnight stay after T&A.Results: The analysis included 411,876 procedures at 48 hospitals. Hospitals’ annual rates of overnight stay following T&A ranged from 3% to 100%, and 7-day revisit rates varied from 0% to 15%. The percentage or rate of 7-day revisits did not differ based on the use of overnight stay following T&A. At hospitals with higher overnight admission rates after T&A, 7-day revisits were more likely to take the form of inpatient admission rather than an ED visit.Conclusions: The current study confirms that pediatric hospitals vary widely in inpatient admission practices following T&A. This variation is not associated with differences in revisit rates at 7 and 30 days related to any cause. Although no mortality was noted in the current study, caution is suggested when deciding on the disposition of patients with comorbid conditions as risks related to various patients, anesthetic, and surgical-related issues exist. Risk stratification with appropriate identification of patients requiring overnight stay may be the most important for preventing acute care revisits after T&A.Keywords: tonsillectomy, emergency room visit, post-tonsillectomy hemorrhage, overnight admission, surgical complication

Hina Walia,1 Rebecca Miller,1 Dmitry Tumin,1 Joseph D Tobias,1,2 Roby Sebastian1,2 1Department of Anesthesiology and Pain Medicine, Nationwide Children’s Hospital, Columbus, OH, USA; 2Department of Anesthesiology, The Ohio State University, Columbus, OH, USA Introduction: As the primary source of smoke exposure is in the home, the smoking behaviors of parents and other caregivers are key determinants of a child’s exposure to secondhand smoke. The perioperative period offers an opportunity to discuss smoking cessation strategies. Methods: This prospective study included 97 parents or caregivers of patients undergoing dental surgery. Caregivers were surveyed in the dental waiting room during the preoperative phase. The primary aim was to determine the feasibility of using the preoperative encounter to offer smoking cessation resources to parents of pediatric patients. The secondary aim was to compare willingness to receive smoking cessation resources according to the knowledge of the risks of secondhand smoking (ie, being aware of secondhand smoking and knowing that it posed a risk to their child). Results: Awareness of risks due to secondhand smoking was 65% in the overall cohort and 58% among current smokers (P=0.284 vs nonsmokers). Among smokers in our study, only a small percentage (12%) were interested in smoking cessation help. Knowledge of the risks of secondhand smoke may not be sufficient for smokers to express willingness to receive help. Conclusion: The outpatient clinic may be a teaching opportunity for smoking cessation for caregivers. However, we found that only a small percentage of caregivers were interested in receiving information about smoking cessation. This was despite the fact they were aware of the potential adverse effects of secondhand smoke on their children. Keywords: smoking cessation, caregivers, survey, health impact

A range of devices and technologies are available to hasten fluid administration time. While new devices may optimize fluid delivery times, impact on subjective experience compared to traditional methods is poorly documented. Our study evaluated administration time and provider experience using two unique methods for fluid administration. Materials and methods: Prospective comparison of objective and subjective outcomes using a novel infusion device (LifeFlow® Rapid Infuser) and the traditional push–pull syringe method in a simulated model of rapid fluid infusion. Ten paired trials were conducted for each of three intravenous catheter gauges. Providers administered 500 mL of isotonic crystalloid through an intravenous catheter with both LifeFlow and a push–pull device. Administration time was compared between devices using paired t-tests. Participants’ subjective physical demand, effort, pain, and fatigue using each device were recorded using 21-point visual analog scales and compared between devices using sign-rank tests. Results: Fluid administration time was significantly decreased with LifeFlow compared to the push–pull device with the 18-gauge catheter (2.5±0.8 vs 3.8±1.0 minutes; 95% CI of difference: 0.9, 1.8 minutes; P

Elisabeth Dewhirst,1 Hina Walia,1 Walter P Samora,2 Allan C Beebe,2 Jan E Klamar,2 Joseph D Tobias1,3 1Department of Anesthesiology and Pain Medicine, Nationwide Children’s Hospital, Columbus, OH, USA; 2Department of Orthopedic Surgery, Nationwide Children’s Hospital, The Ohio State University, Columbus, OH, USA; 3Department of Anesthesiology and Pain Medicine, The Ohio State University, Columbus, OH, USA Introduction: Cerebral oxygenation can be monitored clinically by cerebral oximetry (regional oxygen saturation, rSO2) using near-infrared spectroscopy (NIRS). Changes in rSO2 have been shown to precede changes in pulse oximetry, providing an early detection of clinical deterioration. Cerebral oximetry values may be affected by various factors, including changes in ventilation. The aim of this study was to evaluate the changes in rSO2 during intraoperative changes in mechanical ventilation. Patients and methods: Following the approval of the institutional review board (IRB), tissue and cerebral oxygenation were monitored intraoperatively using NIRS. Prior to anesthetic induction, the NIRS monitor was placed on the forehead and over the deltoid muscle to obtain baseline values. NIRS measurements were recorded each minute over a 5-min period during general anesthesia at four phases of ventilation: 1) normocarbia (35–40 mmHg) with a low fraction of inspired oxygen (FiO2) of 0.3; 2) hypocarbia (25–30 mmHg) and low FiO2 of 0.3; 3) hypocarbia and a high FiO2 of 0.6; and 4) normocarbia and a high FiO2. NIRS measurements during each phase were compared with sequential phases using paired t-tests. Results: The study cohort included 30 adolescents. Baseline cerebral and tissue oxygenation were 81% ± 9% and 87% ± 5%, respectively. During phase 1, cerebral rSO2 was 83% ± 8%, which decreased to 79% ± 8% in phase 2 (hypocarbia and low FiO2). Cerebral oxygenation partially recovered during phase 3 (81% ± 9%) with the increase in FiO2 and then returned to baseline during phase 4 (83% ± 8%). Each sequential change (e.g., phase 1 to phase 2) in cerebral oxygenation was statistically significant (p < 0.01). Tissue oxygenation remained at 87%–88% throughout the study. Conclusion: Cerebral oxygenation declined slightly during general anesthesia with the transition from normocarbia to hypocarbic conditions. The rSO2 decrease related to hypocarbia was easily reversed with a return to baseline values by the administration of supplemental oxygen (60% vs. 30%).

Secure fixation of the epidural catheter is necessary to prevent premature dislodgment and loss of epidural analgesia. Using an in vitro model, the current prospective study evaluates different types of dressings for securement of an epidural catheter by quantifying the force in Newtons (N) required for dislodgment using a digital force gage. Methods: Four methods of epidural catheter securement were used on a simulator mannequin: 1) Suresite® Window Clear Dressing, 2) Op-Site Post-Op® Visible Dressing, 3) Steri-Strips® and Suresite Window Clear Dressing, and 4) Steri-Strips and Op-Site Post-Op Visible Dressing. Each method of securement was assessed 10 times to calculate the mean force required to dislodge the catheter. Mean force of dislodgment for each method was compared using parametric tests. Results: The force (mean ± SD) required for catheter dislodgment for the four methods was 14.0±2.9, 2, 10.7±1.5, 8.6±2.3, and 9.6±2.2 N, respectively. The pairwise difference showed that the Suresite Window Clear Dressing was the best securement method when compared with other methods. Conclusion: Our study demonstrates the advantage of the Suresite Window Clear Dressing in securing the epidural catheter. Future clinical trials are needed to validate these findings.

However, this increase may not translate into acceptance of CAM in the perioperative setting. We surveyed caregivers of patients undergoing surgery to determine their knowledge and acceptance of hypnotherapy, acupuncture, and music therapy as alternatives to standard medication in the perioperative period. Materials and methods: An anonymous, 12-question survey was administered to caregivers of children undergoing procedures under general anesthesia. Caregivers reported their knowledge about hypnotherapy, music therapy, and acupuncture and interest in one of these methods during the perioperative period. CAM acceptance was defined as interest in one or more CAM methods.Results: Data from 164 caregivers were analyzed. The majority of caregivers were 20–40 years of age (68%) and mothers of the patient (82%). Caregivers were most familiar with acupuncture (70%), followed by music therapy (60%) and hypnotherapy (38%). Overall CAM acceptance was 51%. The acceptance of specific CAM modalities was highest for music therapy (50%), followed by hypnotherapy (17%) and acupuncture (13%). In multivariable logistic regression, familiarity with music therapy was associated with greater odds of CAM acceptance (odds ratio=3.36; 95% CI: 1.46, 7.74; P=0.004).Conclusion: Overall CAM acceptance among caregivers of children undergoing surgery was 51%, with music therapy being the most accepted CAM method. Familiarity with music therapy was the only factor that was independently associated with accepting CAM in the perioperative period. The low acceptance for acupuncture and hypnosis in the perioperative situation may be related to insufficient parental knowledge and information.

Although patient-controlled devices are frequently used in patients ≥6 years of age, alternative modes of analgesic delivery are needed in infants.Objective: To examine the safety and efficacy of nurse-controlled analgesia (NCA) in neonates less than 1 year of age.Methods: Data from patients

A total of 37 original cDNA libraries and 9 derivative libraries enriched for rare sequences were produced from Chinese Spring wheat (Triticum aestivum L.), five other hexaploid wheat genotypes (Cheyenne, Brevor, TAM W101, BH1146, Butte 86), tetraploid durum wheat (T. turgidum L.), diploid wheat (T. monococcum L.), and two other diploid members of the grass tribe Triticeae (Aegilops speltoides Tausch and Secale cereale L.). The emphasis in the choice of plant materials for library construction was reproductive development subjected to environmental factors that ultimately affect grain quality and yield, but roots and other tissues were also included. Partial cDNA expressed sequence tags (ESTs) were examined by various measures to assess the quality of these libraries. All ESTs were processed to remove cloning system sequences and contaminants and then assembled using CAP3. Following these processing steps, this assembly yielded 101,107 sequences derived from 89,043 clones, which defined 16,740 contigs and 33,213 singletons, a total of 49,953 "unigenes." Analysis of the distribution of these unigenes among the libraries led to the conclusion that the enrichment methods were effective in reducing the most abundant unigenes and to the observation that the most diverse libraries were from tissues exposed to environmental stresses including heat, drought, salinity, or low temperature.

Background: Cutaneous leiomyomas are benign smooth muscle tumors that comprise three distinct types such as piloleimyoma, angioleiomyoma, and genital leiomyoma. Aim: The objective of this study was to report a series of cases seen in last 8 years in a tertiary care hospital in north India and to discuss their clinicopathologic findings. Material and Methods: Paraffin-embedded blocks of cases reported as cutaneous leiomyoma from 1999 to 2007 were retrieved from the Institute of Pathology, New Delhi, and their clinical parameters were noted. Their histopathological features were reviewed on hematoxylin-eosin stained slides. Immunohistochemistry was performed where necessary. Results: Twenty-seven cases of piloleiomyoma, three cases of angioleiomyoma, five breast leiomyomas, and two scrotal leiomyomas were seen in patients ranging from 21 to 65 years of age, with an average of 38.2 years at presentation. There was a male predominance with 26 males and 11 females (M:F = 2.2:1). Solitary lesions (n = 21) were more common than multiple ( n = 16). The trunk and upper limbs were involved most commonly, comprising 23 of 37 (62.2%) cases. This was followed by lower limb, face, breast, and scrotum. Conclusion: Cutaneous leiomyomas are rare lesions and form an important clinical differential diagnosis of painful papulonodules. These must be biopsied in order to differentiate them from other spindle cell lesions.

Abstract Background Rice and barley are both members of Poaceae (grass family) but have a marked difference in salt tolerance. The molecular mechanism underlying this difference was previously unexplored. This study employs a comparative genomics approach to identify analogous and contrasting gene expression patterns between rice and barley. Results A hierarchical clustering approach identified several interesting expression trajectories among rice and barley genotypes. There were no major conserved expression patterns between the two species in response to salt stress. A wheat salt-stress dataset was queried for comparison with rice and barley. Roughly one-third of the salt-stress responses of barley were conserved with wheat while overlap between wheat and rice was minimal. These results demonstrate that, at transcriptome level, rice is strikingly different compared to the more closely related barley and wheat. This apparent lack of analogous transcriptional programs in response to salt stress is further highlighted through close examination of genes associated with root growth and development. Conclusion The analysis provides support for the hypothesis that conservation of transcriptional signatures in response to environmental cues depends on the genetic similarity among the genotypes within a species, and on the phylogenetic distance between the species.

Abstract Background A large number of genetic variations have been identified in rice. Such variations must in many cases control phenotypic differences in abiotic stress tolerance and other traits. A single feature polymorphism (SFP) is an oligonucleotide array-based polymorphism which can be used for identification of SNPs or insertion/deletions (INDELs) for high throughput genotyping and high density mapping. Here we applied SFP markers to a lingering question about the source of salt tolerance in a particular rice recombinant inbred line (RIL) derived from a salt tolerant and salt sensitive parent. Results Expression data obtained by hybridizing RNA to an oligonucleotide array were analyzed using a statistical method called robustified projection pursuit (RPP). By applying the RPP method, a total of 1208 SFP probes were detected between two presumed parental genotypes (Pokkali and IR29) of a RIL population segregating for salt tolerance. We focused on the Saltol region, a major salt tolerance QTL. Analysis of FL478, a salt tolerant RIL, revealed a small (< 1 Mb) region carrying alleles from the presumed salt tolerant parent, flanked by alleles matching the salt sensitive parent IR29. Sequencing of putative SFP-containing amplicons from this region and other positions in the genome yielded a validation rate more than 95%. Conclusion Recombinant inbred line FL478 contains a small (< 1 Mb) segment from the salt tolerant parent in the Saltol region. The Affymetrix rice genome array provides a satisfactory platform for high resolution mapping in rice using RNA hybridization and the RPP method of SFP analysis.

Abstract Trafficking in women and children is a gross violation of human rights. However, this does not prevent an estimated 800 000 women and children to be trafficked each year across international borders. Eighty per cent of trafficked persons end in forced sex work. India has been identified as one of the Asian countries where trafficking for commercial sexual exploitation has reached alarming levels. While there is a considerable amount of internal trafficking from one state to another or within states, India has also emerged as a international supplier of trafficked women and children to the Gulf States and South East Asia, as well as a destination country for women and girls trafficked for commercial sexual exploitation from Nepal and Bangladesh. Trafficking for commercial sexual exploitation is a highly profitable and low risk business that preys on particularly vulnerable populations. This paper presents an overview of the trafficking of women and girls for sexual exploitation (CSE) in India; identifies the health impacts of CSE; and suggest strategies to respond to trafficking and related issues.
