Factors Affecting the Gut Microbiome in Pediatric Intestinal Failure.

BACKGROUND: There is little data on gut microbiome and various factors that lead to dysbiosis in pediatric intestinal failure (PIF). This study aimed to characterize gut microbiome in PIF and determine factors that may affect microbial composition in these patients. METHODS: This is a single-center, prospective cohort study of children with PIF followed at our intestinal rehabilitation program. Stool samples were collected longitudinally at regular intervals over a 1-year period. Medical records were reviewed, and demographic and clinical data were collected. Medication history including the use of acid blockers, scheduled prophylactic antibiotics, and bile acid sequestrants was obtained. Gut microbial diversity among patients was assessed and compared according to various host characteristics of interest. RESULTS: The final analysis included 74 specimens from 12 subjects. Scheduled prophylactic antibiotics, presence of central line associated bloodstream infection (CLABSI) at the time of specimen collection, use of acid blockers, and ≥50% calories delivered via parenteral nutrition (PN) was associated with reduced alpha diversity, whereas increasing age was associated with improved alpha diversity at various microbial levels ( P value <0.05). Beta diversity differed with age, presence of CLABSI, use of scheduled antibiotics, acid blockers, percent calories via PN, and presence of oral feeds at various microbial levels ( P value <0.05). Single taxon analysis identified several taxa at several microbial levels, which were significantly associated with various host characteristics. CONCLUSION: Gut microbial diversity in PIF subjects is influenced by various factors involved in the rehabilitation process including medications, percent calories received parenterally, CLABSI events, the degree of oral feeding, and age. Additional investigation performed across multiple centers is needed to further understand the impact of these findings on important clinical outcomes in PIF.

Effectiveness of a central line associated blood stream infection protocol in a pediatric population.

BACKGROUND: Central line associated bloodstream infections are a common cause of bacteremia and sepsis in pediatric patients with intestinal failure, secondary to long-term CVC use. METHODS: An IRB approved retrospective chart review was conducted on TPN-dependent patients with IF who had an identified CLABSI and presented to Children's of Alabama's emergency department (ED) and were admitted to the hospital. RESULTS: Forty-four patients were included in the study, 28 in the first 18-month period and 26 in the second, with 10 in both populations. After implementation, mean time from ED presentation to antibiotic ordered and ED admission to antibiotic administered were lower. Mean time between antibiotic administration and admission to the floor was greater, and number of infectious disease consultations was greater. Floor-ICU transfers were lower, readmissions within 30 days was similar, and mean length of stay was similar. CONCLUSION: A collaborative, multidiscipline-supported protocol for the care of patients with IF presenting to the ED enhances efficiency of antibiotic ordering/administration, as well as reduces the number of unplanned floor-ICU transfers.

A Novel Use of Artificial Intelligence to Examine Diversity and Hospital Performance.

BACKGROUND: The US population is becoming more racially and ethnically diverse. Research suggests that cultural diversity within organizations can increase team potency and performance, yet this theory has not been explored in the field of surgery. Furthermore, when surveyed, patients express a desire for their care provider to mirror their own race and ethnicity. In the present study, we hypothesize that there is a positive correlation between a high ranking by the US News and World Report for gastroenterology and gastrointestinal (GI) surgery and greater racial, ethnic, and gender diversity among the physicians and surgeons. METHODS: We used the 2019 US News and World Report rankings for best hospitals by specialty to categorize gastroenterology and GI surgery departments into 2 groups: 1-50 and 51-100. Hospital websites of these top 100 were viewed to determine if racial diversity and inclusion were highlighted in the hospitals' core values or mission statements. To determine the rates of diversity within departments, Betaface (Betaface.com) facial analysis software was used to analyze photos taken from the hospitals' websites. This software was able to determine the race, ethnicity, and gender of the care providers. We examined the racial and ethnic makeup of the populations served by these hospitals to see if the gastroenterologists and surgeons adequately represented the state population. We then ran the independent samples t-test to determine if there was a difference in rankings of more diverse departments. RESULTS: Hospitals with gastroenterology and GI surgery departments in the top 50 were more likely to mention diversity on their websites compared with hospitals that ranked from 51-100 (76% versus 56%; P = 0.035). The top 50 hospitals had a statistically significant higher percentage of underrepresented minority GI physicians and surgeons (7.01% versus 4.04%; P < 0.001). In the 31 states where these hospitals were located, there were more African Americans (13% versus 3%; P < 0.001) and Hispanics (12% versus 2%; P < 0.001), while there were fewer Asians (4% versus 21%; P < 0.001) in the population compared with the faculty. CONCLUSIONS: We used artificial intelligence software to determine the degree of racial and ethnic diversity in gastroenterology and GI surgery departments across the county. Higher ranking hospitals had a greater degree of diversity of their faculty and were more likely to emphasize diversity in their mission statements. Hospitals stress the importance of having a culturally diverse staff, yet their care providers may not adequately reflect the populations they serve. Further work is needed to prospectively track diversity rates over time and correlate these changes with measurable outcomes.

Scheduled Empiric Antibiotics May Alter the Gut Microbiome and Nutrition Outcomes in Pediatric Intestinal Failure.

BACKGROUND: In this study, we aim to determine the effect of scheduled antibiotics on gut microbiome in pediatric intestinal failure (IF) and to evaluate the effect of the gut microbiome on nutrition outcomes in IF. METHODS: Fecal samples were collected at regular intervals from pediatric patients with IF for gut microbiome comparison between 2 cohorts: (group 1) those on scheduled prophylactic antibiotics and (group 2) those who were not on scheduled antibiotics. Gut microbiome composition and diversity were compared among the 2 cohorts. The association among gut microbiome composition, diversity, and nutrition outcomes (mainly ability to decrease parenteral nutrition [PN] energy requirement and ability to attain positive growth) was also determined. RESULTS: The microbiome of patients with IF on scheduled antibiotics differed significantly from those not on scheduled antibiotics. Abundance of certain Gram-negative and pathogenic bacteria (Pseudomonas, Prevotella, and Sutterella) was higher in the scheduled cohort. Patients with decreased Enterobacteriaceae demonstrated a greater ability to demonstrate a reduction in PN requirement, as well as attain positive growth. CONCLUSION: Scheduled antibiotics may alter the gut microbiome in children IF, which in turn may have an influence on important nutrition outcomes in pediatric IF. Further larger, multicenter studies are needed to determine the effect of scheduled antibiotics on the gut microbiome in this patient population and their overall effect on nutrition outcomes.

Effect of the COVID-19 Pandemic on Pediatric Intestinal Failure Healthcare Delivery.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has influenced how healthcare is being provided, particularly in patients whose diagnoses require multidisciplinary care, such as pediatric intestinal failure (IF). We sought to ascertain the effects of the COVID-19 pandemic on healthcare delivery for pediatric patients with IF. METHODS: A 20-question survey was administered to members of the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition Intestinal Rehabilitation (IR) Special Interest Group. Input values were "yes" and "no," along with a free-text response. Following a 10-day open survey period, data were divided into cohorts based on patient population size and disease burden by state. Analysis was then performed using the χ2 test application. RESULTS: Responses from 29 centers were included in analysis. Centers that followed >50 patients on parenteral nutrition (PN) were more likely to have social workers present in telemedicine visits and observed more central line difficulties among families. Centers located in states with <40,000 reported cases of COVID-19 saw patients less frequently and were more likely to withhold changes to PN prescriptions. Additionally, the survey revealed a significant degree of financial hardship and food insecurity among families. CONCLUSION: Many aspects of pediatric IF healthcare delivery have been impacted by the COVID-19 pandemic, both for care providers and caregivers. Despite the availability of telemedicine, IR centers should remain attentive to the global needs of the pediatric IF patient, as well as their families.

Key Determinants for Achieving Enteral Autonomy and Reduced Parenteral Nutrition Exposure in Pediatric Intestinal Failure.

BACKGROUND: We sought to evaluate the relationship between determinants of intestinal failure (IF) and achieving enteral autonomy from parenteral nutrition (PN) in a large single-center cohort of children. METHODS: This is a retrospective chart review of pediatric subjects enrolled in a database for the Center for Advanced Intestinal Rehabilitation at Children's of Alabama from 1989 to 2016. IF was defined as dependence on PN for >60 days. Subjects were included if they were followed since birth or infancy for a minimum of 3 months and sufficient documentation of study variables were available. Gestational age, race, diagnosis, anatomy (percent small and large bowel remaining, presence of ileocecal valve [ICV]), county of residence (rural/urban), and days of PN use were recorded. Kaplan-Meier curves and parametric survival regression models were used to investigate the relationship between the demographic and clinical variables with the length of PN use. RESULTS: Initially, 290 subjects were available to review. After inclusion/exclusion were applied, 158 subjects remained. Gestational age, diagnosis (necrotizing enterocolitis), small-bowel length (>50%), and presence of an ICV were all positive predictors for reaching enteral autonomy. Residual colon length was associated with shorter duration of PN in days. CONCLUSION: Enteral autonomy is a key outcome among children with IF. In our cohort, we found that gestational age, diagnosis, remaining small bowel, and presence of ICV are positive predictors for reaching this important milestone. Colon length is also an important factor with respect to duration of PN in days.

Development of venous thrombi in a pediatric population of intestinal failure.

BACKGROUND/PURPOSE: Although pediatric intestinal failure (IF) is now a survivable diagnosis, children are still at risk for complications. Loss of venous access persists as a leading indication for intestinal transplantation. The goal of this study was to identify risk factors for loss of venous access in a pediatric intestinal failure population on long-term PN. METHODS: We identified all patients who were PN dependent. RESULTS: Patients that developed venous thrombosis had significantly more lines placed in the first 2 years of life compared to those who did not develop thrombosis. Multivariate regression analysis revealed that diagnosis (NEC and gastroschisis) and parental education were significant predictors of venous thrombosis. CONCLUSION: By identifying potential risk factors for thrombus development, interventions can be developed to improve the overall outcome in pediatric IF patients. TYPE OF STUDY: Diagnostic LEVEL OF EVIDENCE: III.

Quintuplets: 5 Cases of NEC. Are There Other Risk Factors?

OBJECTIVE: To review a case of quintuplets with all babies developing necrotizing enterocolitis. METHODS: A retrospective study of preterm quintuplets all developing necrotizing enterocolitis. Clinical outcomes were reviewed. RESULTS: Quintuplets were born at 24 weeks gestation. Each baby developed NEC and was treated. One baby died. Currently the remaining 4 infants are on full enteral nutrition. CONCLUSION: Further studies are needed to better understand this emerging population of multiple birth pregnancy and the frequency of NEC development.

Outcomes of adding acute care nurse practitioners to a Level I trauma service with the goal of decreased length of stay and improved physician and nursing satisfaction.

BACKGROUND: The trauma service experienced preventable delays caused by an Accreditation Council for Graduate Medical Education work restrictions and a 16% increase in patient census. Furthermore, nurses needed a consistently accessible provider for the coordination of care. We hypothesized that using experienced acute care nurse practitioners (ACNPs) on the stepdown unit would improve throughput and decrease length of stay (LOS) and hospital charges. Moreover, we hypothesized that adding ACNPs would improve staff satisfaction. On December 1, 2011, the Vanderbilt University Medical Center Division of Trauma reassigned ACNPs to the stepdown area 5 days a week for a pilot program. METHODS: LOS data from December 1, 2011 through December 1, 2012 was compared with data from the same months from the previous two years and estimated hospital charges and patient days were extrapolated. Physician and nursing surveys were performed. Data from 2010 (n = 2,559) and 2011 (n= 2,671) were averaged and the mean LOS for the entire trauma service was 7.2 days. After adding an experienced ACNP, the average LOS decreased to 6.4 days, a 0.8 day reduction. Per patient, there was a $ 9,111.50 savings in hospital charges, for a reduction of $27.8 million dollars in hospital charges over the 12 month pilot program. RESULTS: A confidential survey administered to attending physicians showed that 100% agreed that a nurse practitioner in the stepdown area was beneficial and helped throughput. Dayshift nurses were surveyed, and 100% agreed or strongly agreed that the ACNPs were knowledgeable about the patient's plan of care, experienced in the care of trauma patients, and improved patient care overall. CONCLUSION: The addition of experienced ACNPs resulted in the decrease of overall trauma service LOS, saving almost $9 million in hospital charges. LEVEL OF EVIDENCE: Economic/decision study, level III.

The effect of pre-pregnancy counselling for women with pre-gestational diabetes on maternal health status.

OBJECTIVE: To assess the impact of pre-pregnancy counselling (PPC) on the health of diabetic women in early pregnancy as compared to their health at the time of PPC. STUDY DESIGN: Retrospective cohort study involving all the diabetic women who attended PPC and subsequently become pregnant in the decade 1997-2007. The proforma had two sections: one for the PPC visit and one for the booking visit. Details on demographic factors, control and complications of diabetes, folic acid, current medication, weight, contraception, smoking and alcohol consumption were documented. RESULTS: Fifty-seven women who became pregnant after PPC were studied. There was optimisation of diabetic control with a significant reduction in HbA1c levels at booking as compared to PPC (7.5% vs 8.8%, p<0.0001). Diabetic surveillance (retinopathy and nephropathy screening) was up to date at the time of booking in >80% of the cases. Alteration of insulin regimes was undertaken in ∼ 1 in 5 women. Folic acid was taken by most patients (48/54) at booking. There was no significant reduction in the number of women who smoked at booking compared to PPC. CONCLUSION: The effect of PPC was evident in the improvements in the markers of health of diabetic women in early pregnancy compared to at the time of PPC.

The Pain Beliefs and Perceptions Inventory: a British replication.

The factorial structure, reliability, and validity of the Pain Beliefs and Perceptions Inventory (PBPI) was investigated in a sample of 84 pain patients drawn from a pain clinic in the United Kingdom. The recovered factorial structure replicated that of a previous study. The 4 derived subscales, Mysteriousness, Self-Blame, Pain Constancy and Pain Permanence, had excellent reliability (internal consistency); Chronbach's alpha was greater than 0.80. However, the construct validity of the PBPI, assessed by examining the association between the subscales and the Coping Strategies Questionnaire (CSQ), was not supported. The results are discussed with particular reference to the interpretative issues concerning 2 of the subscales and their relation to the concept of the 'time line' component of illness representation.
