Breast Pump for Low-Resource Settings

ME450 Capstone Design and Manufacturing Experience: Winter 2015Exclusive breastfeeding for the first six months of life is highly recommended by the United Nations Children’s Fund (UNICEF) and World Health Organization (WHO) based on its extraordinary range of benefits to both mothers and children. However, only 15% of infants aged 0 to 6 months in some least developed countries such as Nigeria and only 38% of infants worldwide are exclusively breastfed. The low breastfeeding rates are due in large part to a mother’s need to return to work, where mothers have no access to breastfeeding or expressing breast milk at work. Existing commercial grade and personal-use breast pumps are cost prohibitive and difficult to maintain for mothers in low-resource settings where clean water is a challenge and electricity is not available. Therefore, the team designed and prototyped a cheap, easy to clean, and easy to maintain breast pump for working mothers in low-resource settings.http://deepblue.lib.umich.edu/bitstream/2027.42/111327/1/09_Report.pd

Imaging the Centromedian Thalamic Nucleus Using Quantitative Susceptibility Mapping.

The centromedian (CM) nucleus is an intralaminar thalamic nucleus that is considered as a potentially effective target of deep brain stimulation (DBS) and ablative surgeries for the treatment of multiple neurological and psychiatric disorders. However, the structure of CM is invisible on the standard T1- and T2-weighted (T1w and T2w) magnetic resonance images, which hamper it as a direct DBS target for clinical applications. The purpose of the current study is to demonstrate the use of quantitative susceptibility mapping (QSM) technique to image the CM within the thalamic region. Twelve patients with Parkinson's disease, dystonia, or schizophrenia were included in this study. A 3D multi-echo gradient recalled echo (GRE) sequence was acquired together with T1w and T2w images on a 3-T MR scanner. The QSM image was reconstructed from the GRE phase data. Direct visual inspection of the CM was made on T1w, T2w, and QSM images. Furthermore, the contrast-to-noise ratios (CNRs) of the CM to the adjacent posterior part of thalamus on T1w, T2w, and QSM images were compared using the one-way analysis of variance (ANOVA) test. QSM dramatically improved the visualization of the CM nucleus. Clear delineation of CM compared to the surroundings was observed on QSM but not on T1w and T2w images. Statistical analysis showed that the CNR on QSM was significantly higher than those on T1w and T2w images. Taken together, our results indicate that QSM is a promising technique for improving the visualization of CM as a direct targeting for DBS surgery
