Instituting a Palliative Care Trigger in a Surgical Intensive Care Unit (SICU): Survey Results of SICU Team Members

Increasing palliative care presence in the intensive care unit (ICU) improves symptom management, increases goals-of-care discussion, and reduces unnecessary procedures in ICU patients. An interdisciplinary study team developed a palliative care trigger program in a 17-bed surgical ICU (SICU). Surgical ICU patients who met 3 triggers (ICU length of stay > 10 days, repeat ICU admission, and metastatic cancer) automatically received a palliative care consult. The purpose of the current study was to survey SICU health care professionals before and after the institution of the palliative care trigger program. Overall, the palliative care trigger program was viewed positively by interdisciplinary team members with increased team communication and decreased resistance for the inclusion of palliative care in the SICU plan of care. The palliative care trigger program was successfully developed and implemented in a SICU and was accepted by the interdisciplinary team members caring for SICU patients. Team member feedback is being used to expand the palliative care trigger program to improve care for SICU patients.

Evaluating enteric methane emissions within a herd of genetically divergent grazing dairy cows

Enteric methane (CH4) emissions of 3 genetic groups (GG) of dairy cows were recorded across the grazing season (early March to late October). The 3 GG were (1) high economic breeding index (EBI) Holstein-Friesian (HF) representative of the top 1% of dairy cows in Ireland at the time of the study (elite), (2) national average (NA) EBI, which were representative of the average HF dairy cow in Ireland, and (3) purebred Jersey (JE) cows. Enteric CH4 was recorded using GreenFeed technology. Seasonal variation in CH4 was observed, with the lowest daily CH4 emissions and CH4 expressed per unit of dry matter intake occurring in spring (253 g/d and 15.56 g/kg, respectively), intermediate in summer (303 g/d and 18.26 g/kg, respectively), and greatest in autumn (324 g/d and 19.80 g/kg, respectively). Seasonal variation was also observed in the proportion of gross energy intake converted to CH4 (Ym); in the spring the Ym was lowest at 0.046, increasing to 0.053 and 0.058 in the summer and autumn, respectively. There was no difference in daily CH4 between the elite and NA, whereas JE had lower CH4 emissions compared with the elite. When expressed per unit of milk solids (fat + protein yield; MS), the elite and JE produced 6.8% and 9.7% less CH4 per kilogram of MS, respectively, compared with NA. There was no difference between the GG for CH4 per unit of DMI or the Ym. This research emphasizes the variation in CH4 emissions across the grazing season and among cows of differing genetic merit for CH4 emission intensities but not for CH4 per unit of DMI or the Ym.

Emergency department visits and hospital admissions for suicidal ideation, self-poisoning and self-harm among adolescents in Canada during the COVID-19 pandemic

BACKGROUND

The COVID-19 pandemic had profound effects on the mental wellbeing of adolescents. We sought to evaluate pandemic-related changes in health care use for suicidal ideation, self-poisoning and self-harm.

METHODS

We obtained data from the Canadian Institute for Health Information on emergency department visits and hospital admissions from April 2015 to March 2022 among adolescents aged 10-18 years in Canada. We calculated the quarterly percentage of emergency department visits and hospital admissions for a composite outcome comprising suicidal ideation, self-poisoning and self-harm relative to all-cause emergency department visits and hospital admissions. We used interrupted time-series methods to compare changes in levels and trends of these outcomes between the prepandemic (Apr. 1, 2015-Mar. 1, 2020) and pandemic (Apr. 1, 2020-Mar. 31, 2022) periods.

RESULTS

The average quarterly percentage of emergency department visits for suicidal ideation, self-poisoning and self-harm relative to all-cause emergency department visits was 2.30% during the prepandemic period and 3.52% during the pandemic period. The level (0.08%, 95% confidence interval [CI] -0.79% to 0.95%) or trend (0.07% per quarter, 95% CI -0.14% to 0.28%) of this percentage did not change significantly between periods. The average quarterly percentage of hospital admissions for the composite outcome relative to all-cause admissions was 7.18% during the prepandemic period and 8.96% during the pandemic period. This percentage showed no significant change in level (-0.70%, 95% CI -1.90% to 0.50%), but did show a significantly increasing trend (0.36% per quarter; 95% 0.07% to 0.65%) during the pandemic versus prepandemic periods, specifically among females aged 10-14 years (0.76% per quarter, 95% CI 0.22% to 1.30%) and females aged 15-18 years (0.56% per quarter, 95% CI 0.31% to 0.81%).

INTERPRETATION

The quarterly change in the percentage of hospital admissions for suicidal ideation, self-poisoning and self-harm increased among adolescent females in Canada during the first 2 years of the COVID-19 pandemic. This underscores the need to promote public health policies that mitigate the impact of the pandemic on adolescent mental health.

Assessing the Feasibility and Implementation of Palliative Care Triggers in a Surgical Intensive Care Unit to Improve Interdisciplinary Collaboration for Patient and Family Care

Although palliative care focuses on supporting patients and families through serious illness, it is underutilized in the surgical intensive care unit (SICU). In 2020, patients in the SICU represented only 2.75% of our palliative team's consults. We hypothesize that utilization of palliative care triggers in the SICU will increase collaboration between SICU and palliative care teams and improve patient/family experiences. After reviewing our team's consultation records and the published literature, a consult trigger program was implemented for patients with a SICU length of stay >10 days, unplanned SICU readmission, or new diagnosis of metastatic cancer. A pre-intervention survey assessed SICU providers' perceptions of palliative care. Retrospective analysis evaluated qualitative and quantitative measures. 97% of SICU providers felt increased palliative care would be helpful. During the 6-month project, January 1, 2021 - June 30, 2021, our palliative team performed 27 triggered consults, representing 3.3% of the total 818 consults performed during this period and thus a 20% increase in SICU palliative consults. Triggered consults represented many primary surgical services and the most common consult reason was length-of-stay. All consults included discussions about goals of care and 16 of the 27 patients/families expressed restorative goals. Numerous notes documented family appreciation.

Implementation of a Virtual Interprofessional ICU Learning Collaborative: Successes, Challenges, and Initial Reactions From the Structured Team-Based Optimal Patient-Centered Care for Virus COVID-19 Collaborators

Initial Society of Critical Care Medicine Discovery Viral Infection and Respiratory illness Universal Study (VIRUS) Registry analysis suggested that improvements in critical care processes offered the greatest modifiable opportunity to improve critically ill COVID-19 patient outcomes.

OBJECTIVES

The Structured Team-based Optimal Patient-Centered Care for Virus COVID-19 ICU Collaborative was created to identify and speed implementation of best evidence based COVID-19 practices.

DESIGN SETTING AND PARTICIPANTS

This 6-month project included volunteer interprofessional teams from VIRUS Registry sites, who received online training on the Checklist for Early Recognition and Treatment of Acute Illness and iNjury approach, a structured and systematic method for delivering evidence based critical care. Collaborators participated in weekly 1-hour videoconference sessions on high impact topics, monthly quality improvement (QI) coaching sessions, and received extensive additional resources for asynchronous learning.

MAIN OUTCOMES AND MEASURES

Outcomes included learner engagement, satisfaction, and number of QI projects initiated by participating teams.

RESULTS

Eleven of 13 initial sites participated in the Collaborative from March 2, 2021, to September 29, 2021. A total of 67 learners participated in the Collaborative, including 23 nurses, 22 physicians, 10 pharmacists, nine respiratory therapists, and three nonclinicians. Site attendance among the 11 sites in the 25 videoconference sessions ranged between 82% and 100%, with three sites providing at least one team member for 100% of sessions. The majority reported that topics matched their scope of practice (69%) and would highly recommend the program to colleagues (77%). A total of nine QI projects were initiated across three clinical domains and focused on improving adherence to established critical care practice bundles, reducing nosocomial complications, and strengthening patient- and family-centered care in the ICU. Major factors impacting successful Collaborative engagement included an engaged interprofessional team; an established culture of engagement; opportunities to benchmark performance and accelerate institutional innovation, networking, and acclaim; and ready access to data that could be leveraged for QI purposes.

CONCLUSIONS AND RELEVANCE

Use of a virtual platform to establish a learning collaborative to accelerate the identification, dissemination, and implementation of critical care best practices for COVID-19 is feasible. Our experience offers important lessons for future collaborative efforts focused on improving ICU processes of care.

1 Ambulatory care visits and admissions for suicidal ideation and self-harm in Canadian adolescents during the COVID-19 pandemic: a population-based analysis

Background

The COVID-19 pandemic has challenged the resiliency of Canada’s adolescent population. Understanding changes in mental healthcare utilization can shed light on the impact the pandemic has had on Canada’s youth.

Objectives

To assess if during the pandemic there has been an increase in the proportion of ambulatory care visits and admissions for suicidal ideation and self-harm among adolescents.

Design/Methods

This was a population-based, interrupted time-series analysis of adolescents 10-18 years presenting to an ambulatory care facility (including emergency department) or admitted to a healthcare facility with R458 (suicidal ideation and emotional symptoms), X60-69 (intentional self-poisoning), and X70-84 (intentional self-harm) codes based on the International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Canada (ICD-10-CA). We used the National Ambulatory Care Reporting System, Discharge Abstract Database, and Hospital Morbidity Database. The primary outcome was ambulatory care visits for a composite of suicidal ideation, intentional self-poisoning, and intentional self-harm. Results were stratified by age and sex and expressed as a rate (proportion of encounters with an outcome per 100 encounters). We compared the differences (delta) in slopes (average increase in outcomes) between April 1, 2015, to March 31, 2020, and April 1, 2020 to March 31, 2021 to determine if the expected rate (pre-pandemic) differed significantly from the observed rate (pandemic).

Results

From April 1, 2020, to March 31, 2021, compared to April 1, 2015, to March 31, 2020, the rate of ambulatory care visits and admissions for all conditions decreased. The average quarterly rate of ambulatory care visits for the composite among males 10-14 years, increased by 40.3%, from 0.57 to 0.8 (slope delta=0.1; 95% CI: 0.02, 0.18; p=0.012). Among females 10-14 years, the rate increased by 85.1%, from 1.81 to 3.35 (slope delta=0.7; 95% CI: 0.43, 0.97; p<0.001). Among males 15-18 years, the rate increased by 29.5%, from 1.56 to 2.02 (slope delta=0.13; 95% CI: -0.02, 0.28; p=0.078). Among females 15-18 years, the rate increased by 33.6%, from 3.18 to 4.25 (slope delta=0.26; 95% CI: -0.16, 0.68; p=0.192). The average quarterly rate of admissions was significant for females 10-14 years and increased by 27.7%, from 8.59 to 10.97 (slope delta=1.99; 95% CI: 0.57, 3.41; p=0.017).

Conclusion

The proportion of ambulatory care visits and admissions for emotional symptoms, suicidal ideation, and self-harm during the first year of the COVID-19 pandemic increased compared to pre-pandemic rates among adolescents 10-14 years in Canada. Our findings underscore the importance of promoting public health policies that mitigate the impact of pandemics on adolescent mental health.

Advancing Antibiotic Stewardship Nursing Practice Through Standardized Education: A Pilot Study

Background Antibiotic resistance is a leading global public health threat. Nurses are well positioned to optimize antibiotic use via targeted antibiotic stewardship (AS) nursing practices. However, standardized AS education for nurses is lacking. The objective of this study was to evaluate the effect of an online AS for nurses continuing education program on nurses' antibiotic resistance, antibiotic, and AS knowledge and their intent to integrate AS into their clinical practice. Method A quasi-experiential pretest-posttest design was used with a convenience sample of nurses at a U.S. academic medical center. Focus groups were conducted with those completing the program. Results Forty-seven of 100 eligible nurses completed the program and the pre- and posttest surveys. Participation resulted in statistically significant increases (p < .05) in antibiotic resistance, antibiotic, and AS knowledge, confidence, and perceptions related to the role of nursing in AS. Focus group participants had multiple recommendations for ways to integrate AS in daily nursing practice. Conclusion Completing a comprehensive AS nursing continuing education program could prove instrumental to motivating nurses to adopt AS nursing practices. [J Contin Educ Nurs. 2022;53(9):417-423.].

An Innovative Model of Pediatric Emergency Department Mental Health Care: Protocol for a Multicenter Type 1 Effectiveness-Implementation Cluster Randomized Trial

Over the past decade, visits to American and Canadian emergency departments (EDs) for child and youth mental health care have increased substantially.^1,2 Acute mental health crises can occur as a result of a variety of concerns, including those that are life threatening (eg, suicide attempts), pose safety concerns (eg, suicidal intentions, aggressive behaviors, alcohol and other drug use), and are physically distressing to the child or youth (eg, panic attacks). ED health care providers play a vital role in assessing the safety and well-being of the child or youth and referring them to services for ongoing care.^3,4 During the ED visit, assessment and care should pinpoint risks, inform treatment, and consider family needs and preferences as part of a patient-centered approach. Yet, this approach to care is not widely adopted in EDs. Most EDs do not require the use of pediatric-specific mental health tools to guide assessments or have patient-centered procedures in place to guide the care of patients with mental health emergencies.^5-7 Our team believes these limitations have led to the provision of acute mental health care that can lack sufficient quality and efficiency. This study protocol describes a trial designed to evaluate if a novel mental health care bundle that was co-designed with parents and youth results in greater improvements in the well-being of children and youth 30 days after seeking ED care for mental health and/or substance misuse concerns compared with existing care protocols. We hypothesize that the bundle will positively impact child and youth well-being, while also providing cost-effective health care system benefits.

Hematochezia in children with acute diarrhea seeking emergency department care - a prospective cohort study

OBJECTIVES

Although the passage of blood in stools in children represents a medical emergency, children seeking emergency department (ED) care remain poorly characterized. Our primary objective was to compare clinical characteristics and etiologic pathogens in children with acute diarrhea with and without caregiver-reported hematochezia. Secondary objectives were to characterize interventions and resource utilization.

METHODS

We conducted a secondary analysis of the Alberta Provincial Pediatric EnTeric Infection TEam (APPETITE) database. Children <18 years presenting to two pediatric EDs within a 24-hour period and <7 days of symptoms were consecutively recruited.

RESULTS

Of 1,061 participants, 115 (10.8%) reported hematochezia at the enrollment visit at which time those with hematochezia, compared to those without, had more diarrheal episodes/24-hour period (9 vs. 6; difference: 2; 95% confidence interval [CI]: 2.0, 4.0; p < 0.001), and were less likely to have experienced vomiting (54.8% vs. 80.2%; difference: -25.4; 95% CI: -34.9, -16.0; p < 0.001). They were more likely to receive intravenous fluids (33.0% vs. 17.9%; difference: 15.2; 95% CI: 6.2, 24.1; p < 0.001) and require repeat health care visits (45.5% vs. 34.7%; difference: 10.7; 95% CI: 0.9, 20.6; p = 0.03). A bacterial pathogen was identified in 33.0% of children with hematochezia versus 7.9% without (difference: 25.1; 95% CI: 16.3, 33.9; p < 0.001); viruses were detected in 31.3% of children with hematochezia compared to 72.3% in those without (difference: -41.0%, 95% CI: -49.9, -32.1; p < 0.001).

CONCLUSION

In children with acute diarrhea, caregiver report of hematochezia, compared to the absence of hematochezia, was associated with more diarrheal but fewer vomiting episodes, and greater resource consumption. The former group of children was also more likely to have bacteria detected in their stool.

Native extracellular matrix orientation determines multipotent vascular stem cell proliferation in response to cyclic uniaxial tensile strain and simulated stent indentation

Cardiovascular disease is the leading cause of death worldwide, with multipotent vascular stem cells (MVSC) implicated in contributing to diseased vessels. MVSC are mechanosensitive cells which align perpendicular to cyclic uniaxial tensile strain. Within the blood vessel wall, collagen fibers constrain cells so that they are forced to align circumferentially, in the primary direction of tensile strain. In these experiments, MVSC were seeded onto the medial layer of decellularized porcine carotid arteries, then exposed to 10%, 1 Hz cyclic tensile strain for 10 days with the collagen fiber direction either parallel or perpendicular to the direction of strain. Cells aligned with the direction of the collagen fibers regardless of the orientation to strain. Cells aligned with the direction of strain showed an increased number of proliferative Ki67 positive cells, while those strained perpendicular to the direction of cell alignment showed no change in cell proliferation. A bioreactor system was designed to simulate the indentation of a single, wire stent strut. After 10 days of cyclic loading to 10% strain, MVSC showed regions of densely packed, highly proliferative cells. Therefore, MVSC may play a significant role in in-stent restenosis, and this proliferative response could potentially be controlled by controlling MVSC orientation relative to applied strain.

•

ECM constrained MVSC align with collagen fibers when cells are strained parallel to collagen.

•

Straining MVSC aligned parallel to the direction of strain increased cell proliferation.

•

Simulated stent strut indentation showed increased cell density surrounding the indented wire.

Organizational Interventions to Support Second Victims in Acute Care Settings: A Scoping Study

OBJECTIVES

Health care providers that experience harm after adverse events have been termed "second victims." Our objective was to characterize the range and context of interventions to support second victims in acute care settings.

METHODS

We performed a scoping study using Arksey and O'Malley's process. A library scientist searched PubMed, Cumulative Index of Nursing and Allied Health, EMBASE, and Cochrane Central Register of Controlled Trials in September 2017, and updated the search in November 2018. We sought gray literature (Canadian Electronic Library, Proquest and Scopus) and searched reference lists of included studies. Stakeholder organizations and authors of included studies were contacted. Two reviewers independently reviewed titles and abstracts and extracted data. A qualitative approach was used to categorize the context and characteristics of the 22 identified interventions.

RESULTS

After screening 5634 titles and abstracts, 173 articles underwent full-text screening. Twenty-two interventions met the criteria and were categorized as providing peer support (n = 8), proactive education (n = 6), or both (n = 8). Programs came from Canada (n = 2), Spain (n = 2), and the United States (n = 18). A specific traumatic event triggered the development of 5 programs. Some programs used a standard definition of second victims, (n = 6), whereas other programs had a broader scope (n = 12). Confidentiality was explicitly assured in 9 peer support programs. Outcome measures were often not reported.

CONCLUSIONS

This is a new area of study with little qualitative data from which to determine whether these programs are effective. Many programs had a similar design, based on the structure proposed by the same small group of experts in this new field. Concerns about potential legal proceedings hinder documentation and study of program effectiveness.

264 Does the Introduction of Ward Round Stickers Improve Surgical Ward Rounds?

Aim

With surgical teams in the NHS pushed to their limit under unprecedented demands, simple and effective ways for maintaining standards of patient care are necessitated. This quality improvement project aims to implement user-friendly and coherent ward round stickers as an adjunct to surgical ward rounds to deliver standardised care.

Method

Baseline performance was measured against The Royal College of Surgeons of Edinburgh Surgical Ward Round Toolkit. Five recorded items were studied including: bloods, venous thromboembolism(VTE) prophylaxis, regular medications, observations, and handover to nursing staff. The surgical team was informed of the audit but not over which dates it would be conducted. In the first cycle, data was collected over a 4-week period. Ward round stickers were then implemented, and a second cycle was completed 2 months later over another 4-week period.

Results

Baseline performance recorded from 74 ward round entries showed checking of bloods, VTE, regular medications, observations and handover ranged from 0% to 65%. After the introduction of ward round stickers, a second cycle was performed from 81 ward round entities. There was significant improvement from baseline with compliance in recording all five items &gt; 85%.

Conclusions

This quality improvement project showed that the use of stickers as an adjunct to surgical ward round is a simple and effective way of evidencing good practice against recommended standards.

An Internet-Based Cognitive Behavioral Program for Adolescents With Anxiety: Pilot Randomized Controlled Trial

BACKGROUND

Internet-based cognitive behavioral therapy (ICBT) is a treatment approach recently developed and studied to provide frontline treatment to adolescents with anxiety disorders.

OBJECTIVE

This study aimed to pilot procedures and obtain data on methodological processes and intervention satisfaction to determine the feasibility of a definitive randomized controlled trial (RCT) to test the effectiveness of a self-managed ICBT program, Breathe (Being Real, Easing Anxiety: Tools Helping Electronically), for adolescents with anxiety concerns.

METHODS

This study employed a two-arm, multisite, pilot RCT. Adolescents aged 13 to 17 years with a self-identified anxiety concern were recruited online from health care settings and school-based mental health care services across Canada between April 2014 and May 2016. We compared 8 weeks of ICBT with ad hoc telephone and email support (Breathe experimental group) to access to a static webpage listing anxiety resources (control group). The primary outcome was the change in self-reported anxiety from baseline to 8 weeks (posttreatment), which was used to determine the sample size for a definitive RCT. Secondary outcomes were recruitment and retention rates, a minimal clinically important difference (MCID) for the primary outcome, intervention acceptability and satisfaction, use of cointerventions, and health care resource use, including a cost-consequence analysis.

RESULTS

Of the 588 adolescents screened, 94 were eligible and enrolled in the study (49 adolescents were allocated to Breathe and 45 were allocated to the control group). Analysis was based on 74% (70/94) of adolescents who completed baseline measures and progressed through the study. Enrolled adolescents were, on average, 15.3 years old (SD 1.2) and female (63/70, 90%). Retention rates at 8 weeks were 28% (13/46; Breathe group) and 58% (24/43; control group). Overall, 39% (14/36) of adolescents provided feedback on completion of the Breathe program. Adolescents' scores on a satisfaction survey indicated a moderate level of satisfaction. All but one adolescent indicated that Breathe was easy to use and they understood all the material presented. The most frequent barrier identified for program completion was difficulty in completing exposure activities. The power analysis indicated that 177 adolescents per group would be needed to detect a medium effect size (d=0.3) between groups in a definitive trial. Data for calculating an MCID or conducting a cost-consequence analysis were insufficient due to a low response rate at 8 weeks.

CONCLUSIONS

Adolescents were moderately satisfied with Breathe. However, program adjustments will be needed to address attrition and reduce perceived barriers to completing key aspects of the program. A definitive RCT to evaluate the effectiveness of the program is feasible if protocol adjustments are made to improve recruitment and retention to ensure timely study completion and increase the completeness of the data at each outcome measurement time point.

Evaluation of a pharmacist-led antimicrobial stewardship service in a pediatric emergency department

Background To improve antimicrobial use, incorporation of a pharmacist in antimicrobial stewardship initiatives in the emergency department has been recommended. Recognizing the potential value, a pharmacist-led antimicrobial stewardship (AMS) service which included review and follow up of microbiology results for patients discharged from the pediatric emergency department (PED) with suspected infections was implemented at our local institution. Objective The objective of this study was to evaluate the impact of pharmacists delivering this service compared to usual care. Setting Pediatric emergency department at the IWK Health Centre in Halifax, Canada. Method This study was completed as a retrospective chart review of pediatric patients discharged from the PED 6 months before and after implementation of the pharmacist-led AMS service. Data was extracted from electronic medical records. Data were reported descriptively and compared using a two-sided chi-square test and ordinal logistic regression. Main outcome measures The primary outcome measure was rate of return visits to the PED within 96 h of initial presentation. Results This study included 1070 patient encounters pre-implementation and 1040 patient encounters post-implementation. The rate of return visits to the PED within 96 h was 12.0% (129/1070) pre-implementation vs. 10.0% (100/1049) post-implementation (p = 0.07). The rate of return visits or hospitalization at 30 days was 22.1% (237/1070) pre-implementation compared to 19.9% (207/1040) in the post-implementation phase (p = 0.21). Inappropriate antimicrobial therapy was identified more often in the pre-implementation phase (7.0%, 68/975) vs. the post-implementation phase (5.0%, 46/952), p = 0.047. Time to notification within the first day after discharge occurred more frequently in the post-implementation phase (53.3%, 80/150) as compared to the pre-implementation phase (40.3%, 52/129, p = 0.0298). Conclusion Although this pharmacist-led AMS service did not significantly affect the rate of return visits or hospitalization, it may have led to more judicious use of antimicrobial agents and faster time to notification.

Decreased placental glypican expression is associated with human fetal growth restriction

Placental mediated fetal growth restriction (FGR) is a leading cause of perinatal morbidity and mortality. Heparan sulphate proteoglycans (HSPG) are highly expressed in placentae and regulate haemostasis. We hypothesise that altered expression of HSPGs, glypicans (GPC) may contribute to the development of FGR and small-for-gestational-age (SGA). GPC expression was determined in first-trimester chorionic villous samples collected from women with later SGA pregnancies and in placentae from third-trimester FGR and gestation-matched uncomplicated pregnancies. The expression of both GPC1 and GPC3 were significantly reduced in first-trimester SGA as well as in the third-trimester FGR placentae compared to controls. This is the first study to report a relationship between altered placental GPC expression and subsequent development of SGA/FGR.

Siglec expression on the surface of human, bull and ram sperm

Sialic acid (Sia) is a major constituent of both the sperm glycocalyx and female reproductive mucosal surface and is involved in regulating sperm migration, uterotubal reservoir formation and oocyte binding. Siglecs (sialic acid-binding immunoglobulin - like lectins) commonly found on immune cells, bind to Sia in a linkage- and sugar-specific manner and often mediate cell-to-cell interactions and signalling. Proteomic and transcriptomic analysis of human and bovine sperm have listed Siglecs, but to date, their presence and/or localisation on sperm has not been studied. Therefore, the aim of this study was to characterise the presence of Siglecs on the surface of bovine, human and ovine sperm using both immunostaining and Western blotting. Siglec 1, 2, 5, 6, 10 and 14 were identified and displayed both species- and regional-specific expression on sperm. Almost universal expression across Siglecs and species was evident in the sperm neck and midpiece region while variable expression among Siglecs, similar among species, was detected in the head and tail regions of the sperm. The possible role for these proteins on sperm is discussed.

Vitamin D status and associated genetic polymorphisms in a cohort of UK children with non-alcoholic fatty liver disease

BACKGROUND

Vitamin D deficiency has been associated with non-alcoholic fatty liver disease (NAFLD). However, the role of polymorphisms determining vitamin D status remains unknown.

OBJECTIVES

The objectives of this study were to determine in UK children with biopsy-proven NAFLD (i) their vitamin D status throughout a 12-month period and (ii) interactions between key vitamin D-related genetic variants (nicotinamide adenine dinucleotide synthase-1/dehydrocholesterol reductase-7, vitamin D receptor, group-specific component, CYP2R1) and disease severity.

METHODS

In 103 paediatric patients with NAFLD, serum 25-hydroxyvitamin D (25OHD) levels and genotypes were determined contemporaneously to liver biopsy and examined in relation to NAFLD activity score and fibrosis stage.

RESULTS

Only 19.2% of children had adequate vitamin D status; most had mean 25OHD levels considered deficient (<25 nmol·L^-1 , 25.5%) or insufficient (<50 nmol·L^-1 , 55.3%). Patients had significantly lower 25OHD levels in winter months (95% CI: 22.7-31.2 nmol·L^-1 ) when compared with spring (30.5-42.1 nmol·L^-1 ; P = 0.0089), summer (36.3-47.2 nmol·L^-1 ; P < 0.0001) and autumn (34.2-47.5 nmol·L^-1 ; P = 0.0003). Polymorphisms in the nicotinamide adenine dinucleotide synthase-1/dehydrocholesterol reductase-7 (rs3829251, rs12785878) and vitamin D receptor (rs2228570) genes were independently associated with increased steatosis; while a group-specific component variant (rs4588) was associated with increased inflammation in liver biopsies.

CONCLUSIONS

Children with NAFLD in the UK have particularly low winter vitamin D status, with vitamin D insufficiency prevalent throughout the year. Polymorphisms in the vitamin D metabolic pathway are associated with histological severity of paediatric NAFLD.

INTERVENTIONS TO ASSIST PARENTS IN ACCURATELY DOSING LIQUID MEDICATIONS FOR THEIR CHILDREN: A SCOPING REVIEW

BACKGROUND

Parents’ inaccurate dosing of liquid medications for their children is common, resulting in treatment failure and potential adverse effects. Educational interventions delivered by health care professionals are a means to help parents properly administer liquid medications.

OBJECTIVES

This scoping review was conducted to identify and describe empirically researched educational interventions that prevent inaccurate dosing of liquid medications by parents of children less than 12 years old.

DESIGN/METHODS

We conducted a scoping review using the Joanna Briggs Institute Methodology for Scoping Reviews. With assistance from a library scientist, we searched PubMed, CINAHL, and Web of Science for English-language articles published before June 2017. We also looked at the reference lists of the included articles and subsequent articles that have cited them to identify additional studies (forward and backward searching). Two reviewers independently screened the retrieved titles and abstracts using predetermined criteria. Only quantitative, empirically designed studies that examined interventions delivered by health care professionals to help parents of children under 12 years old to accurately dose liquid medications were included. We appraised the quality of the included articles using the mixed methods appraisal tool (MMAT) and conducted a thematic analysis to identify trends and patterns.

RESULTS

Of the 180 abstracts identified in the search strategy, 9 studies met our inclusion criteria. We identified four main types of interventions: 1. use of visual aids (n=6); 2. use of advanced counselling strategies (n=2); 3. use of standardized measuring tools (n=3); and, 4. use of standardized units of measurement (n=2). Some studies evaluated more than one type of intervention. The overall quality of the included studies was moderate, with 11.1% (n=1) scoring 0.25, 33.3% (n=3) scoring 0.50, 55.6% (n=5) scoring 0.75, and none scoring 1.0.

CONCLUSION

Dosing accuracy of liquid medication for children by their parents is an important topic. More high quality studies conducted by a variety of research groups are needed to ensure the development and implementation of effective evidence-based educational interventions. There is a lack of standardization in the definition of a dosing error. Consensus regarding a standard definition would help studies be more comparable.

Impact of a Canadian Pediatric Society Position Statement on Trampoline-related Injuries at IWK Health Centre, Halifax, Nova Scotia

Introduction: In 2007, the Canadian Pediatric Society (CPS) advised against the recreational use of trampolines at home and reaffirmed that statement in 2013. We evaluated the impact of this position statement on trampoline-related injuries at the IWK Health Centre in Halifax, Nova Scotia.

Methods: We completed a retrospective analysis (2001-2015) using the IWK Health Centre‘s Canadian Hospitals Injury Reporting and Prevention Program (CHIRPP) database. The time frame was divided into a pre-statement, post-statement, and post-reaffirmed statement. We included data on captured emergency department visits for children aged 0-16 years with trampoline-related injuries. Demographics, location, and injury mechanism were compared using the chi-squared and z tests. The proportions of trampoline injuries for pre-, post-, and post-reaffirmed statements were compared via analysis of variance (ANOVA).

Results: Since the CPS statement, trampoline-related injuries significantly increased at the IWK Health Centre from 0.9% to 1.6% (p<0.001). Injuries increased in children under four years old and decreased in children 10-14 years (p=0.009). Recreational use at home (93%) remained the most common location of the incident (p<0.001). Fractures (n=277) and sprains/soft tissue injuries (n=232) to the ankle, head/neck, or elbow remained the most common injuries and did not significantly change post-statement or post-reaffirmed statement (p>0.05).

Conclusions: Despite the CPS statement, trampoline-related injuries remain an important source of injuries at the IWK Health Centre. The types of injury did not significantly change during this time frame.

Human hepatocyte transplantation for liver disease: current status and future perspectives

Liver transplantation is the accepted treatment for patients with acute liver failure and liver-based metabolic disorders. However, donor organ shortage and lifelong need for immunosuppression are the main limitations to liver transplantation. In addition, loss of the native liver as a target organ for future gene therapy for metabolic disorders limits the futuristic treatment options, resulting in the need for alternative therapeutic strategies. A potential alternative to liver transplantation is allogeneic hepatocyte transplantation. Over the last two decades, hepatocyte transplantation has made the transition from bench to bedside. Standardized techniques have been established for isolation, culture, and cryopreservation of human hepatocytes. Clinical hepatocyte transplantation safety and short-term efficacy have been proven; however, some major hurdles-mainly concerning shortage of donor organs, low cell engraftment, and lack of a long-lasting effect-need to be overcome to widen its clinical applications. Current research is aimed at addressing these problems, with the ultimate goal of increasing hepatocyte transplantation efficacy in clinical applications.

A randomised controlled pilot trial evaluating feasibility and acceptability of a computer-based tool to identify and reduce harmful and hazardous drinking among adolescents with alcohol-related presentations in Canadian pediatric emergency departments

OBJECTIVE

This study piloted procedures and obtained data on intervention acceptability to determine the feasibility of a definitive randomised controlled trial (RCT) of the effectiveness of a computer-based brief intervention in the emergency department (ED).

DESIGN

Two-arm, multi-site, pilot RCT.

SETTING AND PARTICIPANTS

Adolescents aged 12-17 years presenting to three Canadian pediatric EDs from July 2010 to January 2013 for an alcohol-related complaint.

INTERVENTIONS

Standard medical care plus computer-based screening and personalised assessment feedback (experimental group) or standard care plus computer-based sham (control group). ED and research staff, and adolescents were blinded to allocation.

OUTCOMES

Main: change in alcohol consumption from baseline to 1- and 3 months post-intervention. Secondary: recruitment and retention rates, intervention acceptability and feasibility, perception of group allocation among ED and research staff, and change in health and social services utilisation.

RESULTS

Of the 340 adolescents screened, 117 adolescents were eligible and 44 participated in the study (37.6% recruitment rate). Adolescents allocated to the intervention found it easy, quick and informative, but were divided on the credibility of the feedback provided (agreed it was credible: 44.4%, disagreed: 16.7%, unsure: 16.7%, no response: 22.2%). We found no evidence of a statistically significant relationship between which interventions adolescents were allocated to and which interventions staff thought they received. Alcohol consumption, and health and social services data were largely incomplete due to modest study retention rates of 47.7% and 40.9% at 1- and 3 months post-intervention, respectively.

CONCLUSIONS

A computer-based intervention was acceptable to adolescents and delivery was feasible in the ED in terms of time to use and ease of use. However, adjustments are needed to the intervention to improve its credibility. A definitive RCT will be feasible if protocol adjustments are made to improve recruitment and retention rates; and increase the number of study sites and research staff.

The impact of an educational intervention on knowledge about infant crying and abusive head trauma

BACKGROUND

Infants follow a predictable trajectory of increased early crying. Frustration with crying is reported to be a trigger for abusive head trauma (AHT).

OBJECTIVE

To evaluate the impact of postpartum delivery of the educational program, the Period of PURPLE Crying (PURPLE), in a group of first-time mothers. The primary objective was to determine whether there was a change in knowledge about infant crying and shaking after exposure to PURPLE. Factors associated with change in knowledge were also examined.

METHOD

A total of 93 participants were recruited over a four-month period at a tertiary care hospital in Nova Scotia. Pre- and postintervention data were collected.

RESULTS

Knowledge about infant crying increased significantly after program delivery (P=0.001). Low baseline crying knowledge was a significant predictor of increased knowledge about infant crying (P≤0.01). There was an insignificant decrease in shaking knowledge (P=0.5), which may have been the consequence of high baseline knowledge.

CONCLUSION

An educational program for new parents appears to be warranted, especially with respect to improving knowledge about infant crying. This may have a positive benefit in AHT prevention. Additional studies are required to evaluate the impact of the program on other caregivers and on rates of AHT.

Increasing Access to Mental Health Care With Breathe, an Internet-Based Program for Anxious Adolescents: Study Protocol for a Pilot Randomized Controlled Trial

Background

There is a demand to make first-line treatments, including cognitive behavioural therapy (CBT) for adolescent anxiety disorders, more widely available. Internet-based CBT is proposed to circumvent access and availability barriers and reduce health care system costs. Recent reviews suggest more evidence is needed to establish the treatment effects of Internet-based CBT in children and adolescents and to determine related economic impacts.

Objective

This pilot trial aims to collect the necessary data to inform the planning of a full-scale RCT to test the effectiveness of the Internet-based CBT program Breathe (Being Real, Easing Anxiety: Tools Helping Electronically).

Methods

We are conducting a 27-month, 2-arm parallel-group, pilot randomized controlled trial (RCT). Outcomes will inform the planning of a full-scale RCT aimed to test the effectiveness of Internet-based CBT with a population of adolescents with moderate to mild anxiety problems. In the pilot RCT we will: (1) define a minimal clinically important difference (MCID) for the primary outcome measure (total anxiety score using the Multidimensional Anxiety Scale for Children); (2) determine a sample size for the full-scale RCT; (3) estimate recruitment and retention rates; (4) measure intervention acceptability to inform critical intervention changes; (5) determine the use of co-interventions; and (6) conduct a cost-consequence analysis to inform a cost-effectiveness analysis in the full-scale RCT. Adolescents aged 13-17 years seeking care for an anxiety complaint from a participating emergency department, mobile or school-based crisis team, or primary care clinic are being screened for interest and eligibility. Enrolled adolescents are being randomly allocated to either 8 weeks of Internet-based CBT with limited telephone and e-mail support, or a control group with access to a static webpage listing anxiety resources. Adolescents are randomly assigned using a computer generated allocation sequence. Data are being collected at baseline, treatment completion, and at a 3-month follow-up.

Results

Currently, adolescents are being enrolled in the study. Enrolment is taking place between March 2014 and February 2016; data collection will conclude May 2016. We expect that analysis and results will be available by August 2016.

Conclusions

In many communities, the resources available for front-line anxiety treatment are outweighed by the need for care. This pilot RCT is an essential step to designing a robust RCT to evaluate the effectiveness of an Internet-based CBT program for adolescents with moderate to mild anxiety problems.

Variation in the Diagnosis and Management of Appendicitis at Canadian Pediatric Hospitals

OBJECTIVES

The objective was to characterize the variations in practice in the diagnosis and management of children admitted to hospitals from Canadian pediatric emergency departments (EDs) with suspected appendicitis, specifically the timing of surgical intervention, ED investigations, and management strategies.

METHODS

Twelve sites participated in this retrospective health record review. Children aged 3 to 17 years admitted to the hospital with suspected appendicitis were eligible. Site-specific demographics, investigations, and interventions performed were recorded and compared. Factors associated with after-hours surgery were determined using generalized estimating equations logistic regression.

RESULTS

Of the 619 children meeting eligibility criteria, surgical intervention was performed in 547 (88%). After-hours surgery occurred in 76 of the 547 children, with significant variation across sites (13.9%, 95% confidence interval = 7.1% to 21.6%, p < 0.001). The overall perforation rate was 17.4% (95 of 547), and the negative appendectomy rate was 6.8% (37 of 547), varying across sites (p = 0.004 and p = 0.036, respectively). Use of inflammatory markers (p < 0.001), blood cultures (p < 0.001), ultrasound (p = 0.001), and computed tomography (p = 0.001) also varied by site. ED administration of narcotic analgesia and antibiotics varied across sites (p < 0.001 and p = 0.001, respectively), as did the type of surgical approach (p < 0.001). After-hours triage had a significant inverse association with after-hours surgery (p = 0.014).

CONCLUSIONS

Across Canadian pediatric EDs, there exists significant variation in the diagnosis and management of children with suspected appendicitis. These results indicate that the best diagnostic and management strategies remain unclear and support the need for future prospective, multicenter studies to identify strategies associated with optimal patient outcomes.

Gastroenteritis Therapies in Developed Countries: Systematic Review and Meta-Analysis

Context

Gastroenteritis remains a leading cause of childhood morbidity.

Objective

Because prior reviews have focused on isolated symptoms and studies conducted in developing countries, this study focused on interventions commonly considered for use in developed countries. Intervention specific, patient-centered outcomes were selected.

Data Sources

MEDLINE, EMBASE, the Cochrane Database of Systematic Reviews, trial registries, grey literature, and scientific meetings.

Study Selection

Randomized controlled trials, conducted in developed countries, of children aged <18 years, with gastroenteritis, performed in emergency department or outpatient settings which evaluated oral rehydration therapy (ORT), antiemetics, probiotics or intravenous fluid administration rate.

Data Extraction

The study was conducted in accordance with the Cochrane Handbook for Systematic Reviews of Interventions and the PRISMA guidelines. Data were independently extracted by multiple investigators. Analyses employed random effects models.

Results

31 trials (4,444 patients) were included. ORT: Compared with intravenous rehydration, hospitalization (RR 0.80, 95%CI 0.24, 2.71) and emergency department return visits (RR 0.86, 95%CI 0.39, 1.89) were similar. Antiemetics: Fewer children administered an antiemetic required intravenous rehydration (RR 0.40, 95%CI 0.26, 0.60) While the data could not be meta-analyzed, three studies reported that ondansetron administration does increase the frequency of diarrhea. Probiotics: No studies reported on the primary outcome, three studies evaluated hospitalization within 7 days (RR 0.87, 95%CI 0.25, 2.98). Rehydration: No difference in length of stay was identified for rapid vs. standard intravenous or nasogastric rehydration. A single study found that 5% dextrose in normal saline reduced hospitalizations compared with normal saline alone (RR 0.70, 95% CI 0.53, 0.92).

Conclusions

There is a paucity of patient-centered outcome evidence to support many interventions. Since ORT is a low-cost, non-invasive intervention, it should continue to be used. Routine probiotic use cannot be endorsed at this time in outpatient children with gastroenteritis. Despite some evidence that ondansetron administration increases diarrhea frequency, emergency department use leads to reductions in intravenous rehydration and hospitalization. No benefits were associated with ondansetron use following emergency department discharge.

Diagnosing clinically significant dehydration in children with acute gastroenteritis using noninvasive methods: a meta-analysis

OBJECTIVE

To determine the most accurate, noninvasive method of assessing dehydration.

STUDY DESIGN

The following data sources were searched: electronic databases, gray literature, scientific meetings, reference lists, and authors of unpublished studies. Eligible studies were comparative outpatient evaluations that used an accepted reference standard and were conducted in developed countries in children aged <18 years with gastroenteritis. Data extraction was completed independently by multiple reviewers before a consensus was made.

RESULTS

Nine studies that included 1039 participants were identified. The 4-item Clinical Dehydration Scale (CDS), the "Gorelick" score, and unstructured physician assessment were evaluated in 3, 2, and 5 studies, respectively. Bedside ultrasound, capillary digital videography, and urinary measurements were each evaluated in one study. The CDS had a positive likelihood ratio (LR) range of 1.87-11.79 and a negative LR range of 0.30-0.71 to predict 6% dehydration. When combined with the 4-item Gorelick Score, the positive LR was 1.93 (95% CI 1.07-3.49) and negative LR was of 0.40 (95% CI 0.24-0.68). Unstructured dehydration assessment had a pooled positive LR of 2.13 (95% CI 1.33-3.44) and negative LR of 0.48 (95% CI 0.28-0.82) to detect ≥ 5% dehydration.

CONCLUSIONS

Overall, the clinical scales evaluated provide some improved diagnostic accuracy. However, test characteristics indicate that their ability to identify children both with and without dehydration is suboptimal. Current evidence does not support the routine use of ultrasound or urinalysis to determine dehydration severity.

Pediatric Pain Management in the Emergency Department: The Triage Nurses' Perspective

Understanding triage nurses' perspectives of pain management is essential for timely pain care for children in the emergency department. Objectives of this study were to describe the triage pain treatment protocols used, knowledge of pain management modalities, and barriers and attitudes towards implementation of pain treatment protocols.

METHODS

A paper-based survey was administered to all triage nurses at three Canadian pediatric emergency departments, between December 2011 and January 2012.

RESULTS

The response rate was 86% (n=126/147). The mean respondent age was 40 years (standard deviation [SD] 9.3) with 8.6 years (SD 7.7) of triage experience. General triage emergency department (GTED) nurses rated adequacy of triage pain treatment lower than pediatric-only triage emergency department (PTED) nurses (P < .001). GTED nurses reported a longer acceptable delay between triage time and administration of analgesia than PTED nurses (P < .002). Most nurses rated more comfort with a protocol involving administration of acetaminophen (97 mm, interquartile range [IQR] 92, 99) or ibuprofen (97 mm, IQR 93, 100) than for oral morphine (67 mm, IQR 35, 94) or oxycodone (57 mm, IQR 15, 81). The top three reported barriers to triage-initiated pain protocols were monitoring capability, time, and access to medications. Willingness to implement a triage-initiated pain protocol was rated as 81 mm (IQR 71, 96).

DISCUSSION

Triage nurses are willing to implement pain protocols for children in the emergency department, but differences in comfort and experience exist between PTED and GTED nurses. Provision of triage initiated pain protocols and associated education may empower nurses to improve care for children in pain in the emergency department.

Hepatopathy of Mauriac syndrome: a retrospective review from a tertiary liver centre

BACKGROUND

Mauriac syndrome is characterised by growth failure, cushingoid appearance and hepatomegaly which occurs in patients with insulin dependent diabetes and was first described shortly after the introduction of insulin as a treatment for the condition.

OBJECTIVE

To describe the clinical features, histological findings and outcome of young people with glycogenic hepatopathy, the hepatic manifestation of Mauriac syndrome (MS).

DESIGN

Retrospective cohort study.

PATIENTS

Young people with glycogenic hepatopathy.

SETTING

Tertiary paediatric hepatology unit.

RESULTS

Thirty-one young people (16 M), median age of 15.1 years (IQR 14-16.2) presented within the study period. Median age of diagnosis of diabetes was 10 years (IQR 8-11). Median insulin requirement was 1.33 units/kg/day; median HbA1c was 96.7 mmol/mol (IQR 84.7-112.0). Growth was impaired: median height z-score was -1.01 (-1.73 to 0.4) and median body mass index (BMI) z-score was 0.28 (-0.12 to 0.67). Hepatomegaly was universal with splenomegaly in 16%. Transaminases were abnormal with a median aspartate aminotransferase (AST) of 76 IU/L and gamma glutamyltransferase of 71 IU/L. Liver biopsy was undertaken in 19 (61%). All showed enlarged hepatocytes with clear cytoplasm with glycogenated nuclei in 17. Steatosis was present in the majority. Inflammation was present in 8 (42%). Fibrosis was seen in 14 (73%) and was generally mild though 2 had bridging fibrosis. Megamitochondria were described in 7. Presence of megamitochondria correlated with AST elevation (p=0.026) and fibrosis on biopsy (p=0.007). At follow-up 17 children had normal or improved transaminases, in 13 there was no change. Transaminases followed the trend of the child's HbA1c.

CONCLUSIONS

Despite modern insulin regimens and monitoring in children with type 1 diabetes, MS still exists. Significant steatosis, inflammation and fibrosis were all seen in liver biopsies.

Predictors of severe H1N1 infection in children presenting within Pediatric Emergency Research Networks (PERN): retrospective case-control study

OBJECTIVE

To identify historical and clinical findings at emergency department presentation associated with severe H1N1 outcome in children presenting with influenza-like illness.

DESIGN

Multicentre retrospective case-control study.

SETTING

79 emergency departments of hospitals associated with the Pediatric Emergency Research Networks in 12 countries.

PARTICIPANTS

265 children (<16 years), presenting between 16 April and 31 December 2009, who fulfilled Centers for Disease Control and Prevention criteria for influenza-like illness and developed severe outcomes from laboratory confirmed H1N1 infection. For each case, two controls presenting with influenza-like illness but without severe outcomes were included: one random control and one age matched control.

MAIN OUTCOME MEASURES

Severe outcomes included death or admission to intensive care for assisted ventilation, inotropic support, or both. Multivariable conditional logistic regression was used to compare cases and controls, with effect sizes measured as adjusted odds ratios.

RESULTS

151 (57%) of the 265 cases were male, the median age was 6 (interquartile range 2.3-10.0) years, and 27 (10%) died. Six factors were associated with severe outcomes in children presenting with influenza-like illness: history of chronic lung disease (odds ratio 10.3, 95% confidence interval 1.5 to 69.8), history of cerebral palsy/developmental delay (10.2, 2.0 to 51.4), signs of chest retractions (9.6, 3.2 to 29.0), signs of dehydration (8.8, 1.6 to 49.3), requirement for oxygen (5.8, 2.0 to 16.2), and tachycardia relative to age).

CONCLUSION

These independent risk factors may alert clinicians to children at risk of severe outcomes when presenting with influenza-like illness during future pandemics.

Analysis of adipokine concentrations in paediatric non-alcoholic fatty liver disease

BACKGROUND

Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease in children. It is important to distinguish children with more severe disease or steatohepatitis (NASH) from those with the less severe simple steatosis (SS) as prognosis differs. The importance of adipokines in the evolution of NASH is well recognized.

OBJECTIVE

As adipokines are important in mediating inflammation, they may also be useful biomarkers of disease.

METHODS

Plasma from 40 children (30 boys), median age 13.4 years, with liver biopsy-proven NAFLD was analysed. Liver biopsies were scored using the NAFLD activity score and compared with adipokine concentrations.

RESULTS

Median body mass index z-score was 2.12 with a median homeostasis model of assessment- insulin resistance of 4.08. Resistin was lower in NASH than in SS (P = 0.03). Monocyte chemoattractant protein 1 (MCP-1) was also lower in NASH (P = 0.04). MCP-1 was higher in children with severe fibrosis (P = 0.008) with an area under the receiver operating characteristic curve (AUROC) of 0.76. Plasminogen activator inhibitor 1 (PAI-1) was also higher in this group (P = 0.011) with an AUROC of 0.78. There were no significant differences in leptin, adiponectin, adipsin, interleukin (IL) 6, IL10 or tumour necrosis factor α between groups.

CONCLUSION

PAI-1 MCP-1 and resistin were differentially expressed with increasing severity of NAFLD. Though it is unlikely that this profile alone would serve as a biomarker of disease, differences found may contribute to understanding the role of these mediators in NAFLD.

Serum protein N-glycosylation in paediatric non-alcoholic fatty liver disease

OBJECTIVE

We have previously shown the potential of glycomics to distinguish patients with steatosis from patients with non-alcoholic steatohepatitis (NASH) in an adult population. The pattern of disease in paediatric patients is distinct from adults. The objective of this study was to characterize the N -glycomic profile of children with varying degrees of non-alcoholic fatty liver disease (NAFLD) and identify potential biomarker profiles of disease.

METHODS

Serum protein N-glycosylation patterns of 51 paediatric NAFLD patients were assessed with deoxyribonucleic acid sequencer-assisted fluorophore-assisted capillary electrophoresis and compared with histology.

RESULTS

Peak 1 (NGA2F) is the most significantly elevated N-glycan in paediatric NASH patients with peak 5 (NA2) demonstrating the largest decrease. The logarithmically transformed ratio of peak 1 to peak 5 was -0.85 (standard deviation [SD] 0.22) in patients with steatosis and borderline NASH and -0.73 (SD 0.12) in NASH (P = 0.02). The biomarker correlated well with the amount of lobular inflammation with a consistent increase of marker score in ascending stage of lobular inflammation. There was also a trend in differentiating patients with significant fibrosis ≥F2; -0.74 (SD 0.13) from patients with no/minimal fibrosis <F2; -0.86 (SD 0.24), P = 0.06. Analysis of the N-glycans on immunoglobulin G confirmed the undergalactosylation status typical for chronic inflammatory conditions.

CONCLUSIONS

This study is the first glycomic analysis performed in a paediatric NAFLD population. In agreement with the results obtained in adults, B cells play a dominant role in the N-glycan alterations of paediatric NASH patients.

Needs of American relatives of intensive care patients: perceptions of relatives, physicians and nurses

OBJECTIVES

This study investigated differences between the perceptions of American relatives, physicians and nurses concerning the needs of relatives visiting intensive care patients.

DESIGN AND PARTICIPANTS

This was a prospective descriptive study. Perceived needs were measured using the 45 item Critical Care Family Needs Inventory (CCFNI) with 101 relatives visiting as well as 28 physicians and 109 nurses working with the same group of patients.

SETTING

Data were collected using a convenience sample of patients, their relatives visiting, as well as the physicians and nurses working with the same patients in six adult intensive care units in a large American tertiary acute care medical centre with over a 900 bed capacity.

RESULTS AND CONCLUSIONS

There were significant correlations (p<0.05) between the relatives, physicians and nurses on eight of the 45 individual items on the CCFNI. Subscale (Information, Proximity, Assurance, Comfort and Support) scores for the needs perceived by relatives, physicians and nurses were calculated and there were significant differences in the three groups on Information (F=5.90, df=2, p=.0005), Support (F=4.12, df=2, p=.022) and Comfort (F=5.01, df=2, p=.010). Relatives and nurses made multiple comments on the surveys. This is important information for all health care workers to consider in setting visiting policies in adult ICUs and developing approaches such as family centred care.

Analysis of methods of providing anonymity in facial photographs; a randomised controlled study

Clinical images are invaluable in medical teaching and research publications. In the past efforts to conceal patient identity, if any, were limited to a black bar concealing the eyes. However, there is no consensus on this among major journals and publishing houses. This research analyses the effectiveness of blacking out the eyes in facial photographs and evaluates alternative techniques. 126 questionnaires were completed. The average numbers of correct responses out of 30 was 24.64 (82.13%) in the control group, 20.59 (68.63%) in the eyes, 20.42 (68.07%) in the eyes and nose group, and 17.53 (58.43%) in the T-shaped group (eyes, nose and mouth). The traditional method of covering the eyes does significantly decrease recognition, however it is only as effective as covering the nose and mouth. The more of the face that is covered the less likely it is that the person is recognised. However, there are people who remain identifiable no matter how much of the face is covered. This work highlights the importance of obtaining consent prior to publication as well as attempting to hide identity.

Treatment of children with migraine in emergency departments: national practice variation study

OBJECTIVE

Children with migraine may present to an emergency department (ED) when outpatient management has failed; however, only limited research has examined migraine-abortive medications among children.

METHODS

A retrospective chart review of ED presentations for migraine or headache between July 1, 2004, and June 30, 2005, in 10 Canadian pediatric EDs was conducted. A priori, evidence-based treatments were defined as any treatment that was based on high-quality evidence and an absence of opioids as first-line agents.

RESULTS

A total of 2515 records were screened, and 1694 (67.4%) met inclusion criteria. The average age of patients was 12.1 years, 14.5% (95% confidence interval [CI]: 12.1%-17.2%) of patients experienced headache >15 days per month, and 62.6% (95% CI: 55.7%-68.9%) had already used migraine-abortive therapy. Significant variations in practice for all classes of migraine-abortive medications were observed. Dopamine receptor antagonists (prochlorperazine, metoclopramide, or chlorpromazine) (39% [95% CI: 28.4%-50.8%]) and orally administered analgesics (acetaminophen and ibuprofen) (24.5% [95% CI: 23.9%-46.8%]) were prescribed most commonly. Predictors for the use of evidence-based treatment included older age (odds ratio: 1.15 [95% CI: 1.07-1.24]) and a discharge diagnosis of migraine (odds ratio: 1.84 [95% CI: 1.11-3.05]).

CONCLUSIONS

Children presenting to EDs for treatment often have frequent attacks and have experienced failure of outpatient, migraine-abortive efforts. Practice variations were impressive for the care of children with migraine in these Canadian EDs.

The effect of elevated progesterone and pregnancy status on mRNA expression and localisation of progesterone and oestrogen receptors in the bovine uterus

To investigate the effects of pregnancy or post-ovulatory progesterone (P4) supplementation on the expression of oestrogen and P4 receptors (ESRs and PGRs) in the bovine uterus, heifers (n=263) were randomly assigned to the following treatments: i) cyclic, normal P4; ii) cyclic, high P4; iii) pregnant, normal P4; and iv) pregnant, high P4 on days 5, 7, 13 and 16 of pregnancy/oestrous cycle. Elevated P4 was achieved through P4-releasing intravaginal device insertion on day 3 after oestrus, resulting in increased concentrations from day 3.5 to 8 (P<0.05) in the high groups than in the normal groups. Irrespective of treatment, PGR and ESR1 mRNA expressions were highest on days 5 and 7 and decreased on day 13 (P<0.05), while ESR2 mRNA expression increased on day 7 (P<0.05) and similar levels were maintained within the normal P4 groups subsequently. Expression in the high P4 groups decreased on day 13 (P<0.05). PGR-AB and PGR-B protein expressions were high in the luminal and superficial glands on days 5 and 7, but by day 13, expression had declined to very low or undetectable levels and high P4 concentration tended to decrease or decreased significantly (P<0.05) the expression in these regions on days 5 and 7. ESR1 protein expression was high, with no treatment effect. ESR2 protein was also highly expressed, with no clear effect of treatment. In conclusion, early post-ovulatory P4 supplementation advances the disappearance of PGR protein from the luminal epithelium on days 5 and 7, and decreases ESR2 mRNA expression during the mid-luteal phase, but has no effect on PGR or ESR1 mRNA expression.

Human hepatocyte transplantation: state of the art

Hepatocyte transplantation is making its transition from bench to bedside for liver-based metabolic disorders and acute liver failure. Over eighty patients have now been transplanted world wide and the safety of the procedure together with medium-term success has been established. A major limiting factor in the field is the availability of good quality cells as hepatocytes are derived from grafts that are deemed unsuitable for transplantation. Alternative sources of cell, including stem cells may provide a sustainable equivalent to primary hepatocytes. There is also a need to develop techniques that will improve the engraftment, survival and function of transplanted hepatocytes. Such developments may allow hepatocyte transplantation to become an accepted and practical alternative to liver transplantation in the near future.
