Maureen Groer - Preterm Infant Microbiome Maureen Groer - Preterm Infant Microbiome THE PRETERM INFANT MICROBIOME: BIOLOGICAL, BEHAVIORAL AND HEALTH OUTCOMES AT 2 AND 4 YEARS OF AGE
Project Start Date: 13-MAY-2015
Project End Date: 29-FEB-2020
This project will follow 78 Very Low Birth Weight (VLBW) infants previously enrolled in a R21 grant through the age of 4 years. The data gathered over 6 weeks of the NICU stay includes multiple factors that potentially could alter the gut micro biome, such as prenatal and postnatal events and illnesses, amount of human milk received, weekly means of cytokines, chemokine's, growth factors and secretory Immunoglobulin A in the milk, and weekly levels of fecal calprotectin. Stool samples have been preserved for analysis of the micro biome in the current study. Micro biome species and diversities will be measured in the laboratory of Dr. Jack Gilbert at Argonne National Lab using state of the science deep sequencing and amplification of microbial sRNA genes. The micro biome will again be measured in stool samples from these children at the ages of 2 and 4 years. Relationship between the pre and postnatal factors, human milk volume and immunobiology, fecal calprotectin levels and the very early micro biome will be analyzed. The predictive power of the VLBW infant gut micro biome for determining later childhood micro biomes will be analyzed prospectively. The relationships between micro biomes across time and later growth, development and health will be determined. VLBW infants are at risk for both early and later health effects, and the role of the micro biome in these effects will be measured for the first time in this prospective study.

Cecile Lengacher - Efficacy of MBSR Cecile Lengacher - Efficacy of MBSR EFFICACY OF MBSR TREATMENT OF COGNITIVE IMPAIRMENT AMONG BREAST CANCER SURVIVORS
Project Start Date: 1-JUL-2015
Project End Date: 30-JUN-2020
Due to improved detection and treatment, survival rates among breast cancer survivors (BSC) have increased. However, BCS may experience cognitive impairment (CI) following treatment, which has been reported by BCS up to 10 years after chemotherapy (CT). There is limited evidence on whether stress- reducing interventions improve CI in BSC. The primary goal of this application is to establish the Mindfulness- Based Stress Reduction for Breast Cancer (MBSR(BC)) program as an effective treatment for CI in BCS. Specifically we aim to (1) evaluate the extent to which MBSR(BC) compared to the Breast Cancer-Education Support (BCES) program or Usual Care (UC) improves cognitive functioning among BCS off treatment; (2) determine if improvements in cognitive functioning achieved from MBSR(BC) are mediated through increased mindfulness and decreased rumination and stress; (3) evaluate genetic variants as moderators of MBSR(BC) on improvements in CI; and (4) determine the impact of MBSR(BC) on healthcare utilization and costs. To achieve these aims, we will conduct a randomized controlled trial (RCT) among 330 BCS with Stage I-III BC who have received adjuvant CT or CT and radiation. Within this RCT, MBSR(BC) will be delivered to a subpopulation of Spanish speaking BCS. Participants will be randomly assigned in a 1:1:1 ratio to (1) the 6- week MBSR(BC) program; (2) the 6-week BCES program; or (3) UC. The BCES program will match the MBSR(BC) program for time and attention and parallel the group support component of MBSR(BC). Assessments will take place at baseline, 6 weeks,12 weeks and 6 months and include clinical history and demographic information, objective neuropsychological assessments, subjective cognitive and symptom measurements, cost utilization surveys and a blood sample collection for genetic analyses. This study is highly innovative to be the first randomized trial to: 1) evaluate the efficacy of MBSR(BC) among BCS for objective neuropsychological and subjective improvements in cognitive functioning; 2) evaluate genetic profiles as moderators of MBSR(BC) on improving CI; 3) offer the MBSR trial in Spanish in addition to English for the purpose of improving cognition; and 4) determine the effect of MBSR(BC) on CT-induced CI among BCS related to health service utilization costs. MBSR(BC) provides training to promote stress reduction through self-regulation of attention and awareness to stressful events. Our preliminary results show that MBSR(BC) improves subjective cognitive functioning. If MBSR(BC) is found to be effective, it will provide evidence of a viable non-pharmacological method for managing CI in BCS. Additionally, the examination of the effects of the hypothesized mediators may yield new insights for tailoring MBSR(BC) and/or developing additional interventions to aid BCS. The assessment of genetic polymorphisms to explore if risk alleles are associated with improvement in cognitive functioning may demonstrate that specific genetic profiles may modify improvements in CI for those receiving MBSR(BC). Finally, if MBSR(BC) is shown to be effective, this may significantly impact healthcare utilization and cost and produce necessary evidence for clinicians, researchers and policymakers.
