Antibiotic duration and gastric dysmotility in preterm neonates

OBJECTIVES

Prolonged antibiotic use after birth is associated with neonatal feeding intolerance and functional gastrointestinal disorders (FGIDs). A gastric dysrhythmia (tachygastria) with frequencies >4-9 cycles per minute, measured by electrogastrography (EGG), is associated with FGIDs. The relationship between prolonged antibiotic use and % time spent in tachygastria is unknown in preterm infants. We aimed to compare weekly changes in % tachygastria between preterm infants receiving long (>48 h) versus short (≤48 h) courses of antibiotics for early onset sepsis evaluation (initiated at <3 days of life).

METHODS

This was a longitudinal, prospective cohort study of 88 preterm infants (<34 weeks' gestation) with weekly EGG recordings from the first week of life until 40 weeks' post-menstrual age, discharge, or death. We calculated % of EGG recording time in tachygastria and determined the mean across weekly sessions. A mixed effects model assessed variance in % tachygastria between the short- and long-antibiotic exposure groups across all weeks.

RESULTS

Baseline characteristics were similar between the two groups. There was no difference in % tachygastria between short and long antibiotic exposure groups across nine postnatal weeks (p = 0.08).

CONCLUSIONS

Early, prolonged antibiotic exposure among preterm infants may not lead to significant gastric dysrhythmia. Future studies including larger sample sizes and a "no antibiotic" exposure arm are essential in elucidating this potential relationship.

Effects of the electronic health record on job satisfaction of academic pediatric faculty

OBJECTIVE(S)

To evaluate the association of Electronic Health Record (EHR) skills and available support with job satisfaction for pediatric faculty at an academic institution. To identify key opportunities for improvement.

STUDY DESIGN

Cross-sectional study of pediatric academic faculty physicians using a REDCap survey to inquire about faculty EHR skills, support services, and associations between EHR workflow and job satisfaction. Results were analyzed using bivariate testing.

RESULTS

The majority of respondents (n = 127, response rate 37%), rated the effect of EHR workflow on job satisfaction as neutral (36%) or negative (44%). Users with more EHR skills were more likely to indicate a positive effect of the EHR on overall job satisfaction (p = 0.019). 7% of respondents had none of the EHR skills queried and few felt that initial training (35%) or the Information Technology department (26%) were useful in acquiring skills. Two similar divisions, one with three and one without Physician Builders (providers with specialized training in EHR personalization), had statistically significant different EHR satisfaction ratings (p = 0.0012).

CONCLUSIONS

Most faculty indicated a negative/neutral effect of the EHR on their overall job satisfaction. Users who indicated more EHR skills had a higher satisfaction rating. Existing training and support were not helpful to users. The division with the most Physician Builders ranked highest in satisfaction. We speculate that 1) adding EHR skills could increase overall job satisfaction and 2) adding Physician Builder resources could increase skills and satisfaction.

Tachygastria in Preterm Infants: A Longitudinal Cohort Study

OBJECTIVES

Tachygastria is a gastric dysrhythmia (>4 to ≤9 cycles per minute, cpm) associated with gastric hypomotility and gastrointestinal disorders. Healthy preterm infants spend more time in tachygastria than adults; however, normative values are not defined. We sought to determine the percent of time preterm infants spend in tachygastria.

METHODS

We conducted a longitudinal, prospective cohort study with weekly electrogastrography (EGG) recordings in 51 preterm <34 weeks' gestation and 5 term (reference) infants. We calculated percentage recording time in tachygastria (% tachygastria) and determined the mean ± standard deviation (SD) across EGG sessions. Mixed effects model was performed to test weekly variance in % tachygastria and gestational age effect. Successive pre- and post-prandial measurements were obtained to assess reproducibility of % tachygastria. We compared time to achieve full feeds between subjects with % tachygastria within 1 SD from the mean versus % tachygastria >1 SD from mean.

RESULTS

Three hundred seventy-six EGG sessions were completed (N = 56). Mean % tachygastria was 40% with SD ±5%. We demonstrated no change in % tachygastria across 9 postnatal weeks (P = 0.70) and no gestational age effect. No difference was demonstrated between successive pre- (P = 0.91) and post-prandial (P = 0.96) % tachygastria. Infants with 35%-45% tachygastria (within 1 SD from mean) had higher gestational age and less time to achieve full feeds than infants with <35% or >45% tachygastria.

CONCLUSIONS

EGG is a reproducible tool to assess % tachygastria in preterm infants. Clinical significance of increased or decreased % tachygastria needs further investigation to validate if 35%-45% tachygastria is safe for feeding.

Development and Assessment of a Low Literacy, Pictographic Cyclic Vomiting Syndrome Action Plan

OBJECTIVE

To develop and assess an evidence-based, individualized Cyclic Vomiting Syndrome Action Plan (CVSAP) to optimize both preventative and acute care.

STUDY DESIGN

This implementation science project synthesized a combination of clinical practice guidelines, published literature, and clinical experience by a team of CVS clinicians to develop the CVSAP. The tool was developed to include validated pictograms and an automatic, embedded, weight-based dosing calculator to output acute management recommendations. The final version of the CVSAP was tested by patients/caregivers, readability calculators, medical librarians, and clinicians using validated metrics.

RESULTS

All pictograms met the criteria for inclusion in the CVSAP. A composite readability score of 5.32 was consistent with a fifth-grade level. Patients/caregivers (n = 70) judged the CVSAP to be of high quality with consumer information rating form rating of 84.2%. Six medical librarians rated the CVSAP to have 93% understandability and 100% actionability, and 33 clinicians completing the SAM generated a suitability rating of 87.5%.

CONCLUSIONS

The CVSAP visually highlights individualized care plan components to facilitate optimized preventative and acute CVS care. Further investigation will determine if CVSAP increases caregiver confidence and compliance in home management and improves quality of life and clinical outcomes for patients with CVS.

Diversity in Selected Leadership Positions in United States Academic Pediatric Gastroenterology Programs: A Review and Call to Action

ABSTRACT

Women and minorities are underrepresented in leadership positions in academic specialties. We investigated representation of women and minorities in selected leadership positions and in fellowships in North American academic pediatric gastroenterology programs (PGP) via voluntary surveys. We also assessed for factors influencing diversity. We found that 45.8% of Program Directors (PD), 75% of division chiefs (DC), and 71% of Pediatrics department chairs were men. Sixty-three percentage of the PG fellows were women. Most DCs were male professors. Most PDs, DCs, and department chairs were White (70%, 80%, and 88.3%), with Blacks being the least represented group in leadership and also among fellows. We found a higher likelihood of having a White PD if the department chair was White. We found gender and racial disparities in all PGP leadership positions. This data can serve as a guide in efforts to support diversity for both gender and race at all positions and academic ranks.

Comparison of Aerodigestive and Nonaerodigestive Provider Responses to Clinical Case Vignettes

OBJECTIVE

To evaluate differences in practice patterns between aerodigestive and nonaerodigestive providers in pediatric gastroenterology when diagnosing and treating common aerodigestive complaints.

STUDY DESIGN

A questionnaire comprised of clinical vignettes with multiple-choice questions was distributed to both aerodigestive and nonaerodigestive pediatric gastroenterologists. Vignettes focused on management of commonly encountered general gastroenterology and aerodigestive issues, such as gastroesophageal (GE) reflux, aspiration, and feeding difficulties. Tests of equal proportions were used to compare rates of testing and empiric therapy within and across groups. Multivariate analysis was used to assess differences in response rates between aerodigestive and nonaerodigestive providers.

RESULTS

A total of 88 pediatric gastroenterologists from 18 institutions completed the questionnaire. There were 35 aerodigestive gastroenterology providers and 53 nonaerodigestive gastroenterology providers. The nonaerodigestive group included 31 general gastroenterologists and 22 providers with self-identified subspecialty gastroenterology expertise. Aerodigestive specialists were more likely than nonaerodigestive gastroenterologists to pursue testing over empiric therapy in cases involving isolated respiratory symptoms (P < .05); aerodigestive providers were more likely to recommend pH-impedance testing, videofluoroscopic swallow studies, and upper gastrointestinal barium study (P < .05 for each test) depending on the referring physician. For vignettes involving infant GE reflux, both groups chose empiric treatments more frequently than testing (P < .001), although aerodigestive providers were more likely than nonaerodigestive providers to pursue testing like upper gastrointestinal barium studies (P < .05).

CONCLUSIONS

Although some practice patterns were similar between groups, aerodigestive providers pursued more testing than nonaerodigestive providers in several clinical scenarios including infants with respiratory symptoms and GE reflux.

Post-transplant lymphoproliferative disorder resembling Wilms tumor. Diagnostic dilemma: renal biopsy or nephrectomy?

Post-transplant lymphoproliferative disorder is a life-threatening neoplasm that can occur after orthotopic liver transplant. We report a 14-month-old female status-post OLT with an atypical presentation of PTLD as a solitary renal mass. At eight-wk post-transplant, she presented with elevated transaminases, CMV counts (73,000 copies/mL), and EBV counts (35,000 copies/mL). CT scan revealed a solid heterogeneously enhancing right renal mass measuring 2.6 × 2.4 × 3.3 cm. The radiological diagnosis was Wilms tumor, although PTLD could not be excluded. Complete resection of a Wilms tumor is potentially curative. A needle biopsy would upstage the malignancy and result in radiochemotherapy that is deleterious to a liver graft. The mass was not amenable to partial nephrectomy. A total nephrectomy, given life-long nephrotoxic immunosuppressants, was an unfavorable option. Thus, needle biopsy was performed. Histology confirmed monoclonal, EBV-associated PTLD and diffuse large B-cell lymphoma. Her therapy included immunosuppression reduction, cyclophosphamide, steroids, and anti-CD20 monoclonal antibody. Concomitantly, she received Cytogam and gancyclovir. Complete remission was achieved three months after chemotherapy. This case illustrates that young age, CMV infection, and EBV infection are strong risk factors for PTLD. With such risk factors present, any mass or lesion in a solid organ transplant patient should be considered PTLD until proven otherwise.

Systemic capillary leak syndrome associated with compartment syndrome and rhabdomyolysis

Systemic capillary leak syndrome (SCLS) is a rare disorder characterized by recurrent spontaneous episodes of hypovolaemic shock due to marked plasma shifts from the intravascular to the extravascular space. This presents as the characteristic triad of hypotension, haemoconcentration and hypoalbuminemia often with an associated monoclonal gammopathy. We describe a patient with SCLS who required aggressive fluid resuscitation and emergency fasciotomies for compartment syndrome with rhabdomyolysis. At presentation the patient was considered to have severe erythrocytosis and was therefore initially referred to a haematologist, which appears to be a frequent sequence of presentation for patients with SCLS. This patient also highlights the importance of muscle compartment pressure monitoring during volume resuscitation in patients with SCLS.
