Ondansetron in acute food protein-induced enterocolitis syndrome, a retrospective case-control study

BACKGROUND

Therapy for moderate to severe acute food protein-induced enterocolitis syndrome (FPIES) typically consists of intravenous fluids and corticosteroids (traditional therapy). Ondansetron has been suggested as an adjunctive treatment. We aimed to evaluate the efficacy of the parenteral (intravenous or intramuscular) ondansetron vs traditional therapy to resolve the symptoms of acute FPIES.

METHODS

Cases of FPIES who had a positive oral food challenge (OFC) were retrospectively examined at two major hospitals over a two-year period (Rome, Italy; and Sydney, Australia). The efficacy of therapy, based on the percentage of cases who stopped vomiting, was compared in cases who received parenteral ondansetron and in cases who received traditional therapy or no pharmacological therapy.

RESULTS

A total of 66 patients were included: 37 had parenteral ondansetron, 14 were treated with traditional therapy, and 15 did not receive any pharmacological therapy. Nineteen percentage of children treated with ondansetron continued vomiting after the administration of the therapy vs 93% of children who received traditional therapy (P < 0.05, relative risk = 0.2). Children who received ondansetron or no therapy were less likely to require an admission overnight compared with those who received traditional therapy (P < 0.05).

CONCLUSIONS

Parenteral ondansetron is significantly more effective than traditional therapy in resolving acute symptoms of FPIES. The relative risk = 0.2 greatly reduces the bias linked to the lack of randomization. These findings suggest an effective treatment for vomiting in positive FPIES OFCs and allow for more confidence in performing OFCs.

The association between sociodemographic and clinical characteristics and poor glycaemic control: a longitudinal cohort study

AIMS

People with diabetes and poor glycaemic control are at higher risk of diabetes-related complications and incur higher healthcare costs. An understanding of the sociodemographic and clinical characteristics associated with poor glycaemic control is needed to overcome the barriers to achieving care goals in this population.

METHODS

We used linked administrative and laboratory data to create a provincial cohort of adults with prevalent diabetes, and a measure of HbA_1c that occurred at least 1 year following the date of diagnosis. The primary outcome was poor glycaemic control, defined as at least two consecutive HbA_1c measurements ≥ 86 mmol/mol (10%), not including the index measurement, spanning a minimum of 90 days. We used multivariable Cox proportional hazards models to evaluate the association between baseline sociodemographic and clinical factors and poor glycaemic control.

RESULTS

In this population-based cohort of 169 890 people, younger age was significantly associated with sustained poor glycaemic control, with a hazard ratio (HR) of 3.08, 95% CI (2.79-3.39) for age 18-39 years compared with age ≥ 75 years. Longer duration of diabetes, First Nations status, lower neighbourhood income quintile, history of substance abuse, mood disorder, cardiovascular disease, albuminuria and high LDL cholesterol were also associated with poor glycaemic control.

CONCLUSIONS

Although our results may be limited by the observational nature of the study, the large geographically defined sample size, longitudinal design and robust definition of poor glycaemic control are important strengths. These findings demonstrate the complexity associated with poor glycaemic control and indicate a need for tailored interventions.

Gender differences on the interacting effects of marital status and health insurance on long-term colon cancer survival in California, 1995-2014

Objectives

Long-term colon cancer survival is not well explained by main effects. We explored the interaction of age, gender, marital status, health insurance and poverty on 10-year colon cancer survival.

Methods

California registry data were analyzed for 5,776 people diagnosed from 1995 to 2000; followed until 2014. Census data classified neighborhood poverty. We tested interactions with regressions and described them with standardized rates and rate ratios (RR).

Results

The 5-way interaction was significant, suggesting larger 4-way disadvantages among non-Medicare-eligible people. A significant 4-way interaction was a 3-way interaction in non-high poverty neighborhoods only. Private insurance was protective for unmarried men (RR = 1.60) but not women, while it was protective for married women (RR = 1.22) but not men. This pattern seemed explained by lower-incomes of certain groups of unmarried women and married men and more prevalent underinsuring of unmarried men.

Conclusions

Structural inequities related to the institutions of marriage and health care seem to affect women and men quite differently. Policy makers ought to be cognizant of such structural imbalances as future reforms of American health care are considered.

Transvaginal power Doppler ultrasound in pelvic congestion: A prospective comparison with transuterine venography

Purpose: Pelvic congestion is diagnosed by transuterine venography, an invasive procedure requiring sedation and irradiation. Ultrasound may be an alternative but is hindered by slow flow within pelvic veins. In an attempt to counter this, we investigated the possible role of transvaginal power Doppler ultrasound.

Material and Methods: 42 women with a clinical suspicion of pelvic congestion underwent transvaginal ultrasound. Adnexal veins were examined and a congestion score established. Planimetric measurements of adnexal vessels were obtained using power Doppler ultrasound, and uterine and ovarian morphology noted. All women then underwent transuterine venography and agreement with the ultrasound congestion score and morphologic features was determined.

Results: There was a trend towards weak positive correlation between ultrasound and venography congestion scores ( r = 0.29, p = 0.06). However, agreement between scores was poor on an individual basis (95% limits of agreement, −3.9 to +2.7). Planimetric power Doppler assessments of adnexal vascularity were unrelated to venographic congestion. Instead, there was correlation between the number and diameter of ovarian follicles and venographic congestion: women with congestion tended to have significantly more (0.04) and smaller follicles ( p = 0.001).

Conclusion: There was poor individual agreement between ultrasound and venographic estimates of congestion. However, there was a direct relationship between venographic congestion score and ovarian morphology.

Current Practices and Use of Simulation in Neonatal Resuscitation Program Courses Across Canada

BACKGROUND: Simulation is an effective tool in medical education. The extent and manner in which simulation is used within Neonatal Resuscitation Program (NRP) courses across Canada is currently unknown. In order to improve NRP education, current practices must be better understood.

OBJECTIVES: To characterize current practices and use of simulation in NRP courses across Canada.

DESIGN/METHODS: A REDCap survey, consisting of questions about instructor demographics, practices in NRP instruction and use of simulation, was developed and distributed to all NRP instructors across Canada. Simple statistics were used to tabulate responses and the chi-squared test was used to assess differences in simulation use between different types of instructors.

RESULTS: Five hundred sixty nine of 1390 (40.9%) NRP instructors completed the survey. Participants included 88 (15.5%) physicians, 74 (13.0%) respiratory therapists, 345 (60.6%) registered nurses and 28 (4.9%) nurse practitioners. Two hundred fifty eight (45.4%) worked in institutions providing Level III care. Overall, 560 (98.4%) respondents used simulation, of which only 176 (31.4%) reported using high-technology simulation. Only 180 (31.6%) instructors who used simulation reported having received formal training in high-technology simulation. When asked about the role of simulation in NRP instruction, 545 (95.8%) agreed or strongly agreed that simulation is a valuable educational tool in NRP instruction, but only 219 (39.1%) felt comfortable using high-technology simulation. There was no difference in use of high-technology simulation between physician and non-physician instructors (I2 0.90, p=0.34). Of the instructors who used high-technology simulation, 160 (90.9%) and 134 (76.1%) had learners and instructors, respectively, from multiple healthcare disciplines present in some or all sessions. There was a non-significant trend towards higher use of interprofessional learners among physician instructors (I2 3.8, p=0.052). An impressive 554 (98.9%) debriefed after some or all simulation sessions, with only 295 (51.8%) instructors having received formal training in debriefing techniques.

CONCLUSION: Almost all NRP instructors use simulation and feel that it is valuable, though few have received formal training and feel comfortable using high-technology simulation. Most simulation use is low-technology, in keeping with the Canadian Paediatric Society (CPS) recommendations, though the optimal methods of use of simulation in NRP instruction are not known. The majority of instructors debrief with learners, as recommended by the CPS, though only half have had training in debriefing. The results of this study support further investigation into the optimal type of simulation in NRP teaching and more formal education in simulation and debriefing for NRP instructors.

Cost Burden of Raising A Child with Fetal Alcohol Spectrum Disorder

BACKGROUND: In Canada the incidence of Fetal Alcohol Spectrum Disorder (FASD) is estimated to be 1 in 100 live births. FASD is the leading cause of developmental and cognitive disabilities in Canada. No study has examined the cost to parents/caregivers of raising a child with FASD in Canada.

OBJECTIVES: To calculate an estimate of direct and indirect costs associated with raising a child with FASD at the patient level.

DESIGN/METHODS: Cross-sectional study design was used. Two-hundred and thirty (230) participants completed the study tool. Participants included caregivers of children from day of birth to 18 years of age, living in urban and rural communities throughout Canada. Participants completed the Health Services Utilization Inventory (HSUI). Key cost components were elicited: direct costs: medical, education, social services, out-of-pocket costs; and indirect costs: productivity losses. Total average costs per individual with FASD were calculated by summing the costs in each cost component, and dividing by the sample size. Costs were extrapolated to one year. A stepwise multiple regression analysis was used to identify significant determinants of costs and to calculate the adjusted annual costs of raising a child with FASD.

RESULTS: Total adjusted annual costs associated with FASD at the individual level was $31, 640 (95% CI $25,342; $38,642). Severity of the child’s condition, age, and relationship of the individual to the caregiver (biological, adoptive, kinship) were significant determinants of costs (p &lt; 0.001). Thirty-two (32) percent of the total costs were paid by families caring for the children: The total annual cost to parent(s)/caregiver(s) of a child with FASD was $10,124.80. These costs were beyond the costs of raising a healthy child and only associated with costs of FASD.

CONCLUSION: Study results demonstrated thecost burden of FASD in Canada to parents/caregivers. Implications to practice, policy, and research are discussed.

Early Onset Neonatal Sepsis in Canada: 2011-2012

BACKGROUND: Canadian and US studies suggest that the organisms responsible for early-onset neonatal sepsis (EONS) are changing, with an increase in Escherichia coli (EC) as well as antibiotic-resistant organisms. Current Canadian guidelines for prevention and treatment of EONS are based on Group B streptococcus (GBS) as the likely organism. Population-level data may inform updates to these national strategies.

OBJECTIVES: To determine the incidence, types of organisms and corresponding resistance patterns involved in EONS in Canada. To identify how the organisms are affected by maternal antibiotic prophylaxis and other factors.

DESIGN/METHODS: Cases of EONS (defined as positive blood and/or cerebrospinal fluid (CSF) culture at &lt;7 days of age) between January 2011 and December 2012 were identified through the Canadian Paediatric Surveillance Program (CPSP). Neonates were excluded if they were asymptomatic with a positive culture likely to be a contaminant, or if the CSF culture was positive as a result of an intracranial procedure.

RESULTS: Over the 2-year period, 127 cases meeting our criteria were identified, and there were 754,849 total Canadian live births. The incidence for EONS was 0.17/1000 live births. 79.5% of cases presented within the first 24 hours of life, while 15% presented between 72 h-7 days. GBS accounted for 41.7% of cases, while EC accounted for 35.4%. Resistance was noted in 33.9% of cases overall. 55.6% of EC were resistant, with ampicillin resistance being the most common. The species of infecting organism was significantly associated with gestational age, very low birth weight, age at presentation, the mother having received GBS prophylaxis, and rupture of membranes lasting more than 18 h. GBS was most common in term and EC in preterm neonates. The overall EONS case fatality rate was 11%, with most of these being deaths from EC.

CONCLUSION: Our study suggests a lower rate of EONS than historically suggested, with differing dominant organisms based on gestational ages of the neonates. Later ages at presentation and high rates of resistance especially among EC cases further complicate the picture. We recommend a review of the Canadian prevention and treatment guidelines based on our findings.
