Rising National Prevalence of Life-Limiting Conditions in Children in England

BACKGROUND: Life-limiting conditions (LLCs) describe diseases with no reasonable hope of cure that will ultimately be fatal. For children with these diseases, palliative care services should be available but few data are available to estimate the burden of these conditions. METHODS: Children (0–19 years) with LLCs were identified within an English Hospital Episode Statistics dataset (2000/2001–2009/2010) by applying a customized coding framework of the International Classification of Diseases, 10th Revision, disease codes. Prevalence per 10 000 population (0–19 years) was calculated by age, diagnostic group, ethnicity, deprivation, and region for each year. RESULTS: The Hospital Episode Statistics extract contained 175 286 individuals with 1 or more LLCs of which congenital anomalies were the most common (31%). Prevalence increased over 10 years from 25 to 32 per 10 000 population. Prevalence in the South Asian (48 per 10 000); black (42 per 10 000); and Chinese, mixed, and “other” (31 per 10 000) populations were statistically significantly higher compared with the white population (27 per 10 000). Prevalence shows an inverse J-shaped relationship with 5 categories of deprivation, with the highest prevalence in the most deprived areas and the lowest in the second least deprived. CONCLUSIONS: In 2010, the prevalence of LLCs in children in England was double the previously reported estimates and had increased annually in all areas over the past decade. This clearly identifies an escalating need for specialist pediatric palliative care services. When planning services for these increasing needs, the excess prevalence in ethnic minority groups, especially in deprived areas, needs to be considered.

Lead Toxicity in a 14-Year-Old Female With Retained Bullet Fragments

In the past 3 decades, lead levels in North American children have been declining. Despite the decline in lead exposure, lead toxicity remains a significant childhood environmental health hazard. The usual route of lead exposure is through ingestion, but lead toxicity secondary to retained bullet fragments has been well documented in the adult literature. The diagnosis of lead toxicity is often difficult and delayed secondary to vague and transient symptoms. Recognizing high-risk characteristics of bullet fragments can improve clinician awareness to the possibility of lead toxicity. The primary management of patients with continued lead exposure is to remove the source of exposure. However, in the case of retained bullet fragments, initiation of chelation therapy before surgical removal may be essential in preventing systemic toxicity. We present the case of a 14-year-old female with lead toxicity who presented with an 18-month course of chronic abdominal pain, vomiting, and anorexia 2 years after sustaining a gunshot wound to the right leg. The patient was treated with oral succimer and operative removal of bullet fragments.

Patterns of diagnoses among children and young adults with life-limiting conditions: a secondary analysis of a national dataset

Background: Numbers of children and young people with life-limiting conditions are rising, and increasing lifespans require young adults with life-limiting condition to transit to appropriate adult services. Aim: To describe the prevalence of life-limiting condition in children and young adults by age, sex, diagnostic group, ethnicity and deprivation. Design: A secondary analysis of the English Hospital Episode Statistics dataset was undertaken to calculate prevalence per 10,000 population. Setting/participants: Individuals (0–40 years) with life-limiting conditions were identified within an English Hospital Episode Statistics dataset by applying a customised coding framework of International Classification of Diseases, 10th Edition, disease codes. Results: There were 462,962 inpatient hospital admissions for 92,129 individual patients with a life-limiting condition. Prevalence-by-age group curve is U shaped with the highest overall prevalence in the under 1-year age group (127.3 per 10,000), decreasing until age 21–25 years (21.1 per 10,000) before rising steeply to reach 55.5 per 10,000 in the 36–40 -year age group. The distribution by diagnostic group varies by age: congenital anomalies are most prevalent in children until age 16–20 years with oncology diagnoses then becoming the most prevalent. Conclusion: Non-malignant diagnoses are common in children and young adults, and services that have historically focussed on oncological care will need to widen their remit to serve this population of life-limited patients. The diagnosis determining a patient’s life-limiting condition will strongly influence their palliative care service needs. Therefore, understanding the diagnostic and demographic breakdown of this population of teenagers and young adults is crucial for planning future service provision.

A cohort study of children and young people with progressive neuromuscular disorders: clinical and demographic profiles and changing patterns of referral for palliative care.

Background: Progressive neuromuscular disease in children is life limiting and these children and young people would benefit from palliative care services, but data are limited on the number and demography of these children. Aim: To describe the clinical and demographic profile of children referred to a Children’s hospice in the UK with progressive neuromuscular disease. Setting/participants: All children and young people with progressive neuromuscular disorders referred to Martin House Children’s Hospice between 1987 and 2010. Design: Retrospective cohort study Results: 300 children with progressive neuromuscular disease were referred to the hospice. Seventy percent (210) of these children had Duchenne Muscular Dystrophy, 22% (67) had Spinal Muscular Atrophy (34 with Type I) and 8% had other neuromuscular diseases. Numbers of referrals have not significantly increased over the last 15 years, although an increasing number come from a South Asian background (from 4% to 32%) and a higher number of children have conditions other than Duchenne Muscular Dystrophy. A total of 55.3% (166) of all referrals came from areas of the highest deprivation. Survival patterns varied by diagnostic group, but ethnicity and deprivation were not associated with survival in these children. Conclusions: The profile of children with progressive neuromuscular conditions who were referred for palliative care has changed over the last 20 years, with a different spectrum of underlying diagnoses and a greater number from a South Asian background. The higher than expected proportion of children living in areas of high deprivation has been consistent over time.

Reported provision of analgesia to patients with acute abdominal pain in Canadian paediatric emergency departments.

OBJECTIVES Evidence exists that analgesics are underutilized, delayed, and insufficiently dosed for emergency department (ED) patients with acute abdominal pain. For physicians practicing in a Canadian paediatric ED setting, we (1) explored theoretical practice variation in the provision of analgesia to children with acute abdominal pain; (2) identified reasons for withholding analgesia; and (3) evaluated the relationship between providing analgesia and surgical consultation. METHODS Physician members of Paediatric Emergency Research Canada (PERC) were prospectively surveyed and presented with three scenarios of undifferentiated acute abdominal pain to assess management. A modified Dillmans Tailored Design method was used to distribute the survey from June to July 2014. RESULTS Overall response rate was 74.5% (149/200); 51.7% of respondents were female and mean age was 44 (SD 8.4) years. The reported rates of providing analgesia for case scenarios representative of renal colic, appendicitis, and intussusception, were 100%, 92.1%, and 83.4%, respectively, while rates of providing intravenous opioids were 85.2%, 58.6%, and 12.4%, respectively. In all 60 responses where the respondent indicated they would obtain a surgical consultation, analgesia would be provided. In the 35 responses where analgesia would be withheld, 21 (60%) believed pain was not severe enough, while 5 (14.3%) indicated it would obscure a surgical condition. CONCLUSIONS Pediatric emergency physicians self-reported rates of providing analgesia for acute abdominal pain scenarios were higher than previously reported, and appeared unrelated to request for surgical consultation. However, an unwillingness to provide opioid analgesia, belief that analgesia can obscure a surgical condition, and failure to take self-reported pain at face value remain, suggesting that the need exists for further knowledge translation efforts.

Comparison of modified two-point dixon and chemical shift encoded MRI water-fat separation methods for fetal fat quantification: Compare Water-Fat Methods for Fetal Fat

Fetal fat is indicative of the energy balance within the fetus, which may be disrupted in pregnancy complications such as fetal growth restriction, macrosomia, and gestational diabetes. Water‐fat separated MRI is a technique sensitive to tissue lipid content, measured as fat fraction (FF), and can be used to accurately measure fat volumes. Modified two‐point Dixon and chemical shift encoded MRI (CSE‐MRI) are water‐fat separated MRI techniques that could be applied to imaging of fetal fat. Modified two‐point Dixon has biases present that are corrected in CSE‐MRI which may contribute to differences in the fat measurements.

Does obesity affect the non-invasive measurement of cardiac output performed by electrical cardiometry in children and adolescents?

Electrical cardiometry (EC) is a non-invasive and inexpensive method for hemodynamic assessment and monitoring. However, its feasibility for widespread clinical use, especially for the obese population, has yet to be determined. In this study, we evaluated the agreement and reliability of EC compared to transthoracic Doppler echocardiography (TTE) in normal, overweight, and obese children and adolescents. We measured stroke volume (SV) and cardiac output (CO) of 131 participants using EC and TTE simultaneously. We further divided these participants according to BMI percentiles for subanalyses: <85% normal weight (n = 41), between 85 and 95% overweight (n = 7), and >95% obese (n = 83). Due to small sample size of the overweight group, we combined overweight and obese groups (OW+OB) with no significant change in results (SV and CO) before and after combining groups. There were strong correlations between EC and TTE measurements of SV (r = 0.869 and r = 0.846; p < 0.0001) and CO (r = 0.831 and r = 0.815; p < 0.0001) in normal and OW+OB groups, respectively. Bias and percentage error for CO measurements were 0.240 and 29.7%, and 0.042 and 29.5% in the normal and OW+OB groups, respectively. Indexed values for SV were lower in the OW+OB group than in the normal weight group when measured by EC (p < 0.0001) but no differences were seen when measured by TTE (p = 0.096). In all weight groups, there were strong correlations and good agreement between EC and TTE. However, EC may underestimate hemodynamic measurements in obese participants due to fat tissue.

Home safe home: evaluation of a childhood home safety program

BACKGROUND The London Health Sciences Centre Home Safety Program (HSP) provides safety devices, education, a safety video, and home safety checklist to all first-time parents for the reduction of childhood home injuries. The objective of this study was to evaluate the HSP for the prevention of home injuries in children up to 2 years of age. METHODS A program evaluation was performed with follow-up survey, along with an interrupted time series analysis of emergency department (ED) visits for home injuries 5 years before (2007–2013) and 2 years after (2013–2015) implementation. Spatial analysis of ED visits was undertaken to assess differences in home injury rates by dissemination areas controlling differences in socioeconomic status (i.e., income, education, and lone-parent status) at the neighborhood level. RESULTS A total of 3,458 first-time parents participated in the HSP (a 74% compliance rate). Of these, 20% (n = 696) of parents responded to our questionnaire, with 94% reporting the program to be useful (median, 6; interquartile range, 2 on a 7-point Likert scale) and 81% learning new strategies for preventing home injuries. The median age of the respondents babies were 12 months (interquartile range, 1). The home safety check list was used by 87% of respondents to identify hazards in their home, with 95% taking action to minimize the risk. The time series analysis demonstrated a significant decline in ED visits for home injuries in toddlers younger than2 years of age after HSP implementation. The declines in ED visits for home injuries remained significant over and above each socioeconomic status covariate. CONCLUSION Removing hazards, supervision, and installing safety devices are key facilitators in the reduction of home injuries. Parents found the HSP useful to identify hazards, learn new strategies, build confidence, and provide safety products. Initial finding suggests that the program is effective in reducing home injuries in children up to 2 years of age. LEVEL OF EVIDENCE Therapeutic/care management study, level V.

Measuring fetal adipose tissue using 3D water-fat magnetic resonance imaging: a feasibility study

Abstract Purpose: Analysis of fetal adipose tissue volumes may provide useful insight towards assessment of overall fetal health, especially in cases with abnormal fetal growth. Here, we assess whether fetal adipose tissue volume can be reliably measured using 3D water-fat MRI, using a quantitative assessment of the lipid content of tissues. Materials and methods: Seventeen women with singleton pregnancies underwent a fetal MRI and water-only and fat-only images were acquired (modified 2-point Dixon technique). Water and fat images were used to generate a fat signal fraction (fat/(water + fat)) from which subcutaneous adipose tissue was segmented along the fetal trunk. Inter-rater (three readers) and intrarater reliability was assessed using intraclass-correlation coefficients (ICC) for 10 image sets. Relationships between adipose tissue measurements and gestational age and estimated fetal weight percentiles were examined. Results: The ICC of the inter-rater reliability was 0.936 (p < .001), and the ICC of the intrarater reliability was 0.992 (p < .001). Strong positive correlations were found between adipose tissue measurements (lipid volume, lipid volume/total fetal volume, mean fat signal fraction) and gestational age. Conclusions: 3D water-fat MRI can reliably measure volume and quantify lipid content of fetal subcutaneous adipose tissues.

From Aha to Ta-dah: insights during life coaching and the link to behaviour change

ABSTRACT Insight represents a cognitive leap in understanding that is distinct from other types of problem-solving. How moments of insight subsequently link to behaviour has not been investigated in real world settings such as coaching. By extending findings from neuroscience into the field of life coaching, our study examined the link between moments of insight and changes in behaviour in a one group, pre-post, mixed method design. Moments of insight and non-insight were tracked over nine life-coaching sessions with a population of women (N = 6) and their coaches (N = 6). Changes in behaviour were assessed at eight weeks post intervention. Insights occurred five times more often (p = .03) during life coaching than in the previous six months. Analysis of qualitative data showed a narrative pattern between goal-progress, moments of insight, and sustained behaviour change. The coach’s role in evoking insight is explored.
