Global Brain Group

The Global Brain Group is a multidisciplinary group of investigators at the University of Washington, Seattle Children’s and the University of Nairobi. Our mission is to serve infants, children, and adolescents in resource poor settings by conducting research to understand risk factors and mechanisms for neuroimpairment and generating evidence to support best practices for optimizing neurodevelopment and social and emotional well being.

The Global Brain Group provides a forum for peer mentorship, sharing ideas, synergy and collaboration between researchers at academic institutions and non-profit organizations. We meet on a monthly basis for peer mentorship meetings, and journal clubs.

Impact of HIV on Neurodevelopment in Kenya (INK)

The Impact of HIV on Neurodevelopment in Kenya (INK) is an observational cohort study of child neurocognitive impairment in HIV-1-infected children with HIV-uninfected children as a comparison group. This study will involve 2 years of follow-up with annual neurocognitive assessments, and will be based in Nairobi Kenya. The INK Study will estimate the impact of ART on neurocognitive deficits in HIV-infected early-(infancy) and late-treated school-aged children. Separately, we will determine the relative impact of pre-ART HIV disease, response to ART, ART regimen, and immune activation on type and severity of neurocognitive deficits.

Mediational Intervention for Sensitizing Caregivers in Kenya (MISCK)

Pediatric HIV infection is associated with an increased risk of neurodevelopmental deficits. The Mediational Intervention for Sensitizing Caregivers (MISC), an early childhood intervention aimed at improving caregiver-child interactions by facilitating caregiver directed mediated learning, has been shown to improve neurodevelopment. The MISC has been studied extensively as an individual-based intervention administered in the home; however, home-based interventions are time intensive, expensive and difficult to implement on a large-scale. In contrast, group-based interventions are less time-intensive, less costly and provide an extended support network. We hypothesize that implementation of the group-based MISC will be associated with improved neurodevelopment comparable to the individual-based MISC in HIV-infected children ages 1-3 years. We also hypothesize that the group-based MISC will be associated with better caregiver attitudes, improved caregiver mental health and better child HIV-related health outcomes similar to the individual-based MISC. We plan to test these conducting a three-arm pilot randomized control trial of the individual-based MISC versus the group-based MISC versus controls in Nairobi,Kenya. We anticipate that both intervention arms will have improved outcomes compared to the controls. We anticipate the group MISC is a feasible approach that can be evaluated in larger future studies and potentially scaled for programmatic implementation.

INK Neurocognitive Assessment Training
In April 2013, the INK study team carried out a training in Nairobi, Kenya. In January 2014, the INK study team went through further training on validated neurocogntitive tests facilitated by Michael Boivin, PhD, MPH and Global Health Uganda. The training focused on the Bruininks-Oseretsky Test of Motor Proficiency (BOT) and the Kaufman Assessment Battery for Children (KABC), which measures cognitive ability.

MDAT Training
In 2013, Dr. Claudia Crowell, MD facilitated a skype training on the adapted Malawi Developmental Assessment Tool (MDAT) for the Nairobi and Kisumu study teams.

MISC Training
Mediational Intervention for Sensitizing Caregivers (MISC) Training: In January 2013, the MISCK study team traveled to Tororo, Uganda to attend a MISC training facilitated Deborah Givon and Cilly Shohet of the late Pnina Klein’s group at the Bar Ilan University, Israel.

The Regional Voice for Vulnerable Children

The Regional Inter-agency Task Team on Children and AIDS in Eastern and Southern Africa is a network of organisations working together to influence global, regional and national policy formulation and implementation for children and their families. Through advocacy and knowledge management, we work on the three priority areas below to improve the care and support for children.

The Consultative Group on Early Childhood Care and Development (CGECCD)

A global inter-agency consortium with strong links to regional networks and a track record of advocacy and knowledge generation and dissemination at an international level. Established in 1984 by a small group of donor funding agencies, it has evolved into a well-respected global network with committed partner agencies, institutions and professionals involved in the field of ECCD at all levels. The focus on young children (0 to 8yrs), their families and communities remains highly relevant in 2013 when taking into account the very large numbers of young children living in difficult and resource-poor contexts and the effects this has on their overall physical, social and cognitive development and well-being.

Coalition for Children affected by HIV/AIDS

The Coalition brings funders and technical experts together to advocate for the best policy, research, and programs for children because children are a vulnerable population that has too often been overlooked.
