VIRA: A Low-Cost HIV Viral Load Quantification System

Big Ideas LogoViral load testing is increasingly supported as a necessary component of the HIV management cycle. Regular monitoring for treatment failure by a viral load test is endorsed by the World Health Organization as essential to a globally sustainable treatment plan. Tijuana has been identified as the potential site of an HIV epidemic due to both its rising incidence of HIV cases and to its disproportionately large populations of high-risk sex workers and intravenous drug users. A novel detection system called VIRA has been developed to make the viral load test financially and logistically feasible for Tijuana health clinics to incorporate into their treatment and containment strategies. VIRA combines a low-cost centrifuge, automated RNA extraction device, paper-based genetic circuit, and smartphone-based photometric quantification system to yield a fast, easy, and inexpensive point-of- care viral load test which may be implemented in Tijuana and readily adapted to other low-resource settings.

Open Viral Load

Open Viral Load_Pitch Day_CaptionThe Open Viral Load project aims to develop an open-source, affordable genetic assay test for HIV that can be easily modified to test other pathogenic diseases, such as tuberculosis and the Zika virus. As part of the Global TIES organization, the Open Viral Load team is working with both the UC San Diego School of Medicine and the Eduardo Mondlane University in Mozambique. The team will perform preliminary testing in Tijuana, Mexico, followed by secondary testing in Mozambique. This project will allow low resource communities to receive the regular testing they need in order to know the status of their viral disease or to quickly diagnose patients with other pathogenic illnesses. This in turn will help doctors issue proper treatment to those in their community.

Hombres Verdaderos

This project will improve women’s health outcomes by stopping domestic violence (DV) before it starts. Leveraging behavioral tools, the program engages young, at-risk adolescent boys, ages 11 to 14 years old, from poor districts in Barranquilla, Colombia. Through workshops and youth-driven media campaigns, the boys will learn about DV prevention and become advocates for change. Participants will undertake a month-long series of play-based workshops on relevant themes, including power, oppression and the effects of gender expectations. The project will enlist older adolescent volunteers to help lead the workshops and create positive role models for the boys. The campaigns will be designed by the students with the help of the volunteers, and will be disseminated to each participant’s online social circle. If this pilot program is successful, it could be scaled-up regionally by the Ministry for Women and Gender Equality in the Atlantic region of Colombia.

MAMA-OPE

 

Mama Ope proposes to develop a cell phone based lung-monitoring device that could be used to radically improve the early diagnosis of pneumonia. The affordability and wide availability of cell phones make them an innovative platform for the development of simple medical diagnosis capabilities for use in the field. This is especially true in under-developed countries where skilled medical practitioners and their most sophisticated devices are often thin on the ground. The cell phone based prototype, coupled with specially developed cell phone applications, will make possible a detailed analysis and preliminary diagnosis of individual lung crackles through digitized audio obtained from the patient’s chest. To ensure that the lung sounds are of sufficient signal strength, the team intends to couple the cellphone to a modified passive stethoscope. In addition, the stethoscope will be embedded in a vest to ensure continuous monitoring. Since the recorded sound can be stored on the cell phone as a digital file, it can be sent later on for expert analysis through the cloud.

Visualize: Saving Lives with Training for Cervical Cancer Screening

Visualize: Saving Lives with Training for Cervical Cancer Screening (UC Berkeley)Every year cervical cancer causes 275,000 deaths worldwide. Screening for cervical cancer significantly reduces this mortality rate, given that most cervical cancer cases caught early are treatable. Visual inspection of the cervix with acetic acid (VIA) is a low-cost and effective method to screen for cervical cancer. VIA is not widely used, however, due to a lack of training and awareness of the method. With proper training and follow-up, VIA can avert 68% of cervical cancer related deaths; thus saving an estimated 150,000 lives in low and lower-middle income countries. The aim of this project is to design and implement a trainer and training program to teach VIA to midwives in Ghana, implementing three phases. Phase 0, which has already been completed, was to develop a low-cost, low-fidelity simulator to assist in training of midwives on VIA. Phase 1 is to develop an implementation plan to launch this program in Ghana and begin training a small group of midwives over the next year. Phase 2 will leverage the initial target group of midwifery students and train them to teach VIA to other midwives in Ghana. This allows more women to get screened for cervical cancer and detect pre-cancerous cells early, thus allowing these women to get the treatment they need to save their lives.

A Novel Approach to Remediate Groundwater Fluoride Contamination in Nalgonda, India

 

Globally, 200 million people are at risk of developing dental/skeletal fluorosis by drinking groundwater containing toxic levels of fluoride that surpass the WHO limit. Although many defluoridation technologies have proven to be effective in labs, most are technologically and/or culturally inappropriate for remote rural areas like Nalgonda, India. Given the pressing need for a more sustainable removal method, this project proposes to: I) use raw bauxite ore to develop a defluoridation technology that is locally sourced and affordable, highly effective, culturally appropriate, technically feasible, robust, and requires minimal operation/maintenance, and II) design business models based on successes and failures of previous services targeted at low-income users to provide a reliable source of defluoridated water at an incremental price that encourages user uptake.

Keti Klaba: A Safe Place for Girls

 

Keti Klaba addresses mental health in Nepalese girls through interactive lessons and community service. Led by Nepali university women, and supplied with adaptive kits of lessons and resources, these clubs provide girls with strong role models, incentives to stay in school, and increased social support from peers and community members. Mental health is a sensitive topic in Nepal, so this program will focus on building general social support to avoid the negative impacts of stigma surrounding programs that address mental health. Through interactive lessons and community service, the central goals of the Keti Klaba (Girl’s Clubs) project are to improve the mental health of pre-adolescent girls in Nepal, and to provide an incentive for girls to continue their education. By the first year, the project will establish 2 Keti Klaba in Nepal.

Clean Water For Crops: As Simple as Sand and Seeds

Slow-sand filtration (SSF) is a tertiary treatment process that has been widely used for drinking water treatment. This technology has yet to be applied to wastewater treatment on a large scale. Pathogen reduction can be further enhanced by the addition of seeds from Moringa oleifera (a typical tree in Guatemala), which have proteins with antimicrobial properties. This project proposes to construct and operate a pilot-scale slow seed-sand filtration system at UC Davis to assess the feasibility of this technology, then to build a pilot-scale system in Sololá, Guatemala in order to adjust the system to local conditions. If successful, the pilot project will serve to encourage the community to build a full-scale treatment system.

Project Drsti: A Sustainable Method for Alleviating Vitamin A Deficiency

This project proposes an innovative strategy to alleviate Vitamin A (VA) deficiency in the developing world by harnessing the metabolic power of a probiotic bacterium, Lactobacillus casei. By engineering L. casei to produce provitamin A (β-carotene) during yogurt fermentation, the team can develop a safe and sustainable method of increasing dietary intake of VA. This provitamin A biofortified (i.e., enhanced) yogurt can support VA status and benefit the health of populations in India who consume yogurt as a staple. Moreover, the bacteria strain can be produced inexpensively, freeze-dried into a room-temperature-stable powder, and seamlessly integrated into existing yogurt production cycles. As L. casei is common in many different fermentations processes, this strain could be adapted for use in many other human and animal food sources. Once this strain becomes established in a fermentation system, it will self-perpetuate to ensure a sustainable source of dietary β-carotene.
