  • “I enjoy building a partnership with my patients and families over time.”

I enjoy building a partnership with my patients and their families over time. We share the same goal of improving the health of the child, and collaborating with families on that goal is one of the most rewarding aspects of my work.

Nutrition is one of the basic needs parents provide for their children, so it can be especially challenging when there is difficulty with that process. As a parent myself, I understand. That's why I try to focus on how the illness is impacting the child and the entire family. It is very rewarding to see treatment improve a child's symptoms and to help them thrive and grow.

I always make the time to fully discuss the family's concerns. Understanding how a child's illness impacts his or her quality of life allows me to better tailor a treatment plan for their needs. I believe that taking the time to truly listen to my patients and their families makes all the difference.

Text Message Intervention (TEACH) Improves Quality of Life and Patient Activation in Celiac Disease: A Randomized Clinical Trial. journal of pediatrics Haas, K., Martin, A., Park, K. T. 2017

Abstract

To determine the impact of the Text Message Educational Automated Compliance Help (TEACH) text message intervention as a pragmatic approach for patient engagement among adolescents with celiac disease (CD) as measured by gluten-free diet (GFD) adherence, patient activation, and quality of life (QOL).Randomized controlled trial with patient recruitment at a pediatric, university-based hospital and through social media; 61 participants ages 12-24 years with CD diagnosed at least 1 year were enrolled. The TEACH intervention cohort received 45 unique text messages over a 3-month study period while the control group received standard of care treatment. Primary outcome measures included objective markers of GFD adherence included serum tissue transglutaminase IgA and deamidated gliadin peptide IgA levels. Secondary patient-reported outcomes collected via online survey included the Celiac Dietary Adherence Test, National Institutes of Health (NIH) Patient-Reported Outcomes Measurement Information System (PROMIS) Global Short Form measure of QOL, Celiac Symptom Index, and Patient Activation Measure. All measures were assessed at enrollment and after the 3-month study period. Statistical analysis performed using the 2-tailed paired Student t test.Among the TEACH intervention group, there was significant improvement comparing enrollment scores with 3-month follow-up scores in patient activation (Patient Activation Measure score 63.1 vs 72.5, P=.01) and QOL (NIH PROMIS Global Mental Health 50.8 vs 53.3, P=.01 and NIH PROMIS Global Physical Health 50.8 vs 57.7, P=.03). There was no statistically significant difference in patient-reported or objectively measured GFD adherence.TEACH is an effective intervention among patients with CD to improve patient activation and QOL, even among a cohort with GFD adherence at baseline.ClinicalTrials.gov: NCT02458898.

Mass cytometry reveals a distinct immunoprofile of operational tolerance in pediatric liver transplantation. Pediatric transplantation Lau, A. H., Vitalone, M. J., Haas, K., Shawler, T., Esquivel, C. O., Berquist, W. E., Martinez, O. M., Castillo, R. O., Krams, S. M. 2016

Abstract

Long-term IS in transplant patients has significant morbidity, poorer quality of life, and substantial economic costs. TOL, defined as graft acceptance without functional impairment in the absence of IS, has been achieved in some pediatric LT recipients. Using mass cytometry, peripheral blood immunotyping was performed to characterize differences between tolerant patients and patients who are stable on single-agent IS. Single-cell mass cytometry was performed using blood samples from a single-center pediatric LT population of operationally tolerant patients to comprehensively characterize the immune cell populations in the tolerant state compared with patients on chronic low-dose IS. Specific T-cell populations of interest were confirmed by flow cytometry. This high-dimensional phenotypic analysis revealed distinct immunoprofiles between transplant populations as well as a CD4(+) TOT (CD4(+) CD5(+) CD25(+) CD38(-/lo) CD45RA) that correlates with tolerance in pediatric LT recipients. In TOL patients, the TOT was significantly increased as compared to patients stable on low levels of IS. This TOT cell was confirmed by flow cytometry and is distinct from classic Treg cells. These results demonstrate the power of mass cytometry to discover significant immune cell signatures that have diagnostic potential.

Role of imaging in the evaluation of inflammatory bowel disease: How much is too much? World journal of radiology Haas, K., Rubesova, E., Bass, D. 2016; 8 (2): 124-131

Abstract

Inflammatory bowel disease (IBD) is a lifelong condition with waxing and waning disease course that requires reassessment of disease status as well as screening for complications throughout a patient's lifetime. Laboratory testing, endoscopic assessment, and fecal biomarkers are often used in the initial diagnosis and ongoing monitoring of a patient with IBD. Imaging plays an integral role in the diagnosis and evaluation of IBD. Different imaging modalities can be used over the course of a patient's lifetime, from the initial screening and diagnosis of IBD, to determining the extent of intestinal involvement, monitoring for disease activity, and evaluating for complications of uncontrolled IBD. The various imaging modalities available to the provider each have a unique set of risks and benefits when considering cost, radiation exposure, need for anesthesia, and image quality. In this article we review the imaging techniques available for the evaluation of IBD including fluoroscopic small bowel follow-through, computed tomography enterography, magnetic resonance enterography, and transabdominal ultrasound with particular focus on the judicious use of imaging and the risks and benefits of each option. We also review the risks of ionizing radiation, strategies to reduce exposure to ionizing radiation, and current imaging guidelines among pediatric and adult patient with IBD.
