Successful implementation of virtual care to overcome the challenges of managing gestational diabetes during the COVID-19 pandemic: a quality improvement project.

At the start of the COVID-19 pandemic, the Jim Pattison Diabetes and Pregnancy (JP DAP) clinic quickly switched from in-person to virtual care for patients with gestational diabetes (GDM) to reduce the risk of viral transmission. Poor glycaemic control in pregnancies increases the risk of maternal-fetal complications and thus women with GDM require education, frequent follow-up and treatment to reduce these risks. Delays in care could potentially result in increased maternal-fetal complications. We conducted a prospective, single-centre quality improvement (QI) study of women with GDM who attended the JP DAP clinic and delivered between 1 September 2019 and 31 March 2021. 2123 singleton pregnancies between 1 September 2019 and 31 March 2021 with GDM were analysed for this study. The time of referral to see the endocrinologist was lower than baseline in the first wave but rose significantly in the second wave. No-shows for appointments increased in the first wave but were lower than baseline after the implementation of time slots. There was no special cause variation for maternal-fetal complications pre pandemic, first wave or during the second wave. A patient satisfaction survey reported that 93% of respondents strongly agreed or agreed with the statement 'I was satisfied with the care provided to me over the telephone appointments'. The GDM education package, online educational videos in Hindi and English and the glucometer smartphone application helped to maintain the time of referral to first endocrinologist appointment in the first wave and therefore were considered an effective substitute for in-person education. Despite the delays in care seen in the second wave, there was no increase in maternal-fetal complications. Our clinic plans to continue using virtual tools for the foreseeable future.

Vitamin A is systemically bioavailable after intratracheal administration with surfactant in an animal model of newborn respiratory distress.

Chronic lung disease (CLD) is a major cause of long-term morbidity in extremely LBW infants with respiratory distress syndrome. Parenteral vitamin A administration decreases the risk of CLD. We tested the hypothesis that intratracheal vitamin A administration with surfactant is systemically bioavailable without interfering with the functional properties of exogenous surfactant. Newborn piglets were ventilated with 100% FiO2 and sequential saline lavage induced respiratory distress syndrome. During lung injury induction, ventilator changes were allowed, but none were made following treatment allocation. Animals were assigned by chance in a blinded control trial to three groups: I=control; II=surfactant; III=surfactant+vitamin A. Hemodynamics, lung mechanics, and blood gases were measured following instrumentation, pre- and posttreatment for 4 h, at which time the liver was sampled for retinol determination. All parameters improved in animals receiving surfactant. A significant interaction existed between time and group for PaO2 and alveolar-arterial oxygen difference (A-aDO2). Hepatic levels of retinol were higher (p<0.001) in animals receiving retinyl acetate. Intratracheal administration of surfactant+vitamin A did not alter the beneficial effects of surfactant on lung compliance and gas exchange. Intratracheal Vitamin A was associated with rapid hepatic uptake. Further studies are warranted.

Bloodstream infections in pediatric ECLS: usefulness of daily blood culture monitoring and predictive value of biological markers. The British Columbia experience.

INTRODUCTION: The incidence of bloodstream infection (BSI) in extracorporeal life support (ECLS) is reported between 0.9 and 19.5%. In January 2006, the Extracorporeal Life Support Organization (ELSO) reported an overall incidence of 8.78% distributed as follows: respiratory: 6.5% (neonatal), 20.8% (pediatric); cardiac: 8.2% (neonatal) and 12.6% (pediatric). METHOD: At BC Children's Hospital (BCCH) daily surveillance blood cultures (BC) are performed and antibiotic prophylaxis is not routinely recommended. Positive BC (BC+) were reviewed, including resistance profiles, collection time of BC+, time to positivity and mortality. White blood cell count, absolute neutrophile count, immature/total ratio, platelet count, fibrinogen and lactate were analyzed 48, 24 and 0 h prior to BSI. A univariate linear regression analysis was performed. RESULTS: From 1999 to 2005, 89 patients underwent ECLS. After exclusion, 84 patients were reviewed. The attack rate was 22.6% (19 BSI) and 13.1% after exclusion of coagulase-negative staphylococci (n = 8). BSI patients were significantly longer on ECLS (157 h) compared to the no-BSI group (127 h, 95% CI: 106-148). Six BSI patients died on ECLS (35%; 4 congenital diaphragmatic hernias, 1 hypoplastic left heart syndrome and 1 after a tetralogy repair). BCCH survival on ECLS was 71 and 58% at discharge, which is comparable to previous reports. No patient died primarily because of BSI. No BSI predictor was identified, although lactate may show a decreasing trend before BSI (P = 0.102). CONCLUSION: Compared with ELSO, the studied BSI incidence was higher with a comparable mortality. We speculate that our BSI rate is explained by underreporting of "contaminants" in the literature, the use of broad-spectrum antibiotic prophylaxis and a higher yield with daily monitoring BC. We support daily surveillance blood cultures as an alternative to antibiotic prophylaxis in the management of patients on ECLS.

Right-sided cardiac involvement in osteogenesis imperfecta.

Skeletal manifestations are the hallmark of the osteogenesis imperfecta group of disorders. Extraskeletal involvement may, however, contribute significantly to morbidity. Structural cardiovascular anomalies reported in osteogenesis imperfecta include aortic root dilatation and aortic and mitral valve dysfunction. Herein is reported the first case of involvement of the right side of the heart in osteogenesis imperfecta.

Fatal congenital hypertrophic cardiomyopathy and a pancreatic nodule morphologically identical to focal lesion of congenital hyperinsulinism in an infant with costello syndrome: case report and review of the literature.

Costello syndrome is characterized by constitutional mutations in the proto-oncogene HRAS, causing dysmorphic features, multiple cardiac problems, intellectual disability, and an increased risk of neoplasia. We report a male infant with dysmorphic features, born prematurely at 32 weeks, who, during his 3-month life span, had an unusually severe and ultimately fatal manifestation of hypertrophic cardiomyopathy and hyperinsulinemic hypoglycemia. Molecular studies in this patient demonstrated the uncommon Q22K mutation in the HRAS gene, diagnostic of Costello syndrome. The major autopsy findings revealed hypertrophic cardiomyopathy, congenital myopathy, and a 1.4-cm pancreatic nodule that was positive for insulin expression and morphologically identical to a focal lesion of congenital hyperinsulinism. Sequencing of KCNJ11 and ABCC8, the 2 most commonly mutated genes in focal lesion of congenital hyperinsulinism, revealed no mutations. While hyperinsulinism is a recognized feature of RASopathies, a focal proliferation of endocrine cells similar to a focal lesion of hyperinsulinism is a novel pathologic finding in Costello syndrome.

The Pediatric Investigators Collaborative Network on Infections in Canada study of predictors of hospitalization for respiratory syncytial virus infection for infants born at 33 through 35 completed weeks of gestation.

BACKGROUND: Infants born at 33 through 35 completed weeks of gestation (33-35GA) are at risk for severe respiratory syncytial virus (RSV) infection, and palivizumab prophylaxis lowers hospitalizations for RSV infection by as much as 80%. The 33-35GA cohort comprises 3-5% of annual births; thus expert panels recommend limiting prophylaxis to situations in which frequency or health care impact of RSV infection is high. This study sought to identify independent risk factors for hospitalization for RSV infection. METHODS: This was a multicenter, prospective, observational cohort study of 33-35GA infants followed through their first RSV season (2001/2002 or 2002/2003). Baseline data were collected by interview with parents and review of medical records. Respiratory tract illnesses were identified by monthly phone calls, and medical records were reviewed for emergency room visits or hospitalizations. Risk factors were determined by stepwise logistic regression. RESULTS: Of 1,860 enrolled subjects, 1,832 (98.5%) were followed for at least 1 month, and 1,760 (94.6%) completed all follow-ups. Of 140 (7.6%) subjects hospitalized for respiratory tract illnesses, 66 infants had proven RSV infection. Independent predictors for hospitalization for RSV infection were: day-care attendance (odds ratio, 12.32; 95% confidence interval, 2.56, 59.34); November through January birth (odds ratio, 4.89; 95% confidence interval, 2.57, 9.29); preschool age sibling(s) (odds ratio, 2.76; 95% confidence interval, 1.51, 5.03); birth weight <10th percentile (odds ratio, 2.19; 95% confidence interval, 1.14, 4.22); male gender (odds ratio, 1.91; 95% confidence interval, 1.10, 3.31); > or = 2 smokers in the home (odds ratio, 1.87; 95% confidence interval, 1.07, 3.26); and households with >5 people, counting the subject (odds ratio, 1.79; 95% confidence interval, 1.02, 3.16). Family history of eczema (odds ratio, 0.42; 95% confidence interval, 0.18, 0.996) was protective. CONCLUSIONS: Specific host/environmental factors can be used to identify which 33-35GA infants are at greatest risk of hospitalization for RSV infection and likely to benefit from palivizumab prophylaxis.

The correlation of seizures in newborn infants with significant acidosis at birth with umbilical artery cord gas values.

OBJECTIVE: To correlate umbilical blood gas variables with neonatal seizures in neonates with significant acidosis at birth (pH < or = 7.1). METHODS: We reviewed the maternal and neonatal charts of 238 patients at a gestational age of 32 weeks or more with cord gases done at delivery and an umbilical artery pH of 7.1 or less. All infants transferred to the neonatal intensive care unit were studied, and those with neonatal seizures secondary to hypoxic ischemic encephalopathy were identified. We used the perinatal outcome of early neonatal seizures secondary to hypoxic ischemic encephalopathy to divide the patients into two groups. The relationship between the umbilical artery parameters of pH, base deficit, partial oxygen pressure (pO(2)), partial carbon dioxide pressure (pCO(2)), and the neonatal outcome of seizures were determined with Student t tests and multiple logistic regression analysis. RESULTS: Umbilical artery base deficit, pO(2), and pCO(2) were significantly elevated in newborns who had seizures, whereas cord pH was decreased. Using multiple regression analysis the variable neonatal seizure was predicted only by low umbilical artery pH. A pH of less than 7 was more sensitive (73.8%) than a base excess of -16 (52.5%) in predicting the development of neonatal seizures. CONCLUSION: Our data suggest that severe fetal acidemia identified by a pH less than 7.0 was the most important umbilical blood gas variable for predicting early onset of neonatal seizures.

Describing Intravenous Extravasation in Children (DIVE Study).

BACKGROUND: Extravasation, the inadvertent leakage of intravenous (IV) medication from the vein into the surrounding tissue, is a iatrogenic cause of patient injury. Extravasation has been reported to occur in 0.1% to 6.5% of hospital inpatients. The incidence may be higher among children because they have multiple risk factors, including small and fragile veins, decreased peripheral circulation, capillary leakage, and flexible subcutaneous tissue. OBJECTIVES: To describe the incidence of extravasation at a pediatric tertiary care hospital, to identify the agents causing extravasation, and to describe the use of antidotes to manage identified cases. A secondary objective was to describe adverse drug effects associated with the antidotes administered. METHODS: The medical records of pediatric patients with documented extravasation of an IV medication between January 1, 2006, and August 31, 2008, were analyzed retrospectively. The appropriateness of antidote use was determined in terms of adherence to the institution's protocol for treatment of extravasation. RESULTS: A total of 42 patients had documented extravasation, for an overall incidence of 0.04% per patient-day. Of the 40 cases in which location was documented, 12 (30%) occurred on the general pediatric wards, 10 (25%) on the surgical ward, 9 (22%) in the neonatal intensive care unit, 5 (12%) in the pediatric intensive care unit, 3 (8%) in day care, and 1 (2%) in the emergency department. The most common medications involved were fluids for IV administration (18 [43%]), potassium chloride (11 [26%]), antibiotics (8 [19%]), total parenteral nutrition (8 [19%]), calcium chloride (2 [5%]), and epinephrine (2 [5%]). Multiple drugs were involved in some cases of extravasation. The decision to administer an antidote and the choice of antidote (if required) were appropriate in 50% of the cases. No adverse drug effects were reported with use of antidotes. CONCLUSIONS: The incidence of extravasation was low. The medications most commonly involved were similar to those reported in the literature. Antidotes were well tolerated but were appropriately used in only half of the events. Prospective trials are needed to determine the clinical severity of injury and to assess the effectiveness and safety of antidotes.

Umbilical artery blood gas parameters in neonates with early onset seizures who die.

OBJECTIVE: To relate umbilical artery blood gas parameters to mortality among neonates with hypoxic-ischaemic encephalopathy related to early onset seizures. DESIGN: Population cohort study. SETTING: British Columbia Women's Hospital. POPULATION: Forty-seven infants at >or=32 weeks of gestation admitted to NICU with early onset seizures secondary to hypoxic-ischaemic encephalopathy with umbilical artery blood gases done at delivery. METHODS: Patients were divided into two groups: (1) Infants with neonatal seizures who survived, and (2) infants with neonatal seizures who died related to hypoxic-ischaemic encephalopathy complications. Comparison of umbilical artery pH, PO(2), PCO(2), base deficit was done between the two groups with Student's t tests. MAIN OUTCOME MEASURES: Umbilical artery pH, PO(2), PCO(2) and base deficit. RESULTS: The PO(2) was significantly higher in the group that expired (18.36 +/- 9.15 vs 12.33 +/- 7.51). There were no significant differences in any other blood gas parameters between the groups. CONCLUSION: Neither the umbilical artery pH nor base deficit is predictive of neonatal death in infants with hypoxic-ischaemic encephalopathy with seizures. The finding of a high PO(2) in neonates who died may indicate an inability of those infants to efficiently extract oxygen from blood.
