Smartphones: The Future of Disease Detection and Diagnosis

Smartphones_Healthcare Disease DetectionDr. Aydogan Ozcan is revolutionizing disease detection and diagnosis. The electrical engineer and bioengineer from the University of California, Los Angeles has developed a microscope that utilizes smartphones.

Smartphones seem a simple alternative to expensive lab equipment. “We have close to six billion cell phone subscribers today,” Ozcan said on the timeliness of his development. Of these users, 70 percent come from developing countries that have a greater need for this microscope.

The system weighs about 200 grams and is able to identify particles as small as 100 nanometers. According to Charles Choi of Scientific American, the microscope can also detect relatively large viruses like HIV and harmful bacteria present in food and water.

The device is easy to use, which means more people can use the smartphone microscope for their benefit. The portability and cost-effectiveness of the device may prove invaluable in remote areas without easy access to medical facilities or trained personnel.

How exactly does the microscope function?

Instead of lenses, this device creates images electronically, according to a New York Times article by Anne Eisenberg. Choi explains that molecules known as fluorophores “[that] fluoresce under certain wavelengths of light” identify and locate the target particles to which they attach.

A blue laser shined onto the particles excites them, creating a hologram from which information can be extracted. The hologram may prove quicker than microscopes in disease detection and diagnosis, according to Eisenberg.

This speed and effectiveness could play a crucial role in future research by, for instance, facilitating the screening of entire regions. This could help gather information on how diseases spread and subsequently inform future responses, Ozcan said.

Ozcan continues to develop his research for the betterment of global healthcare. Holomic LLC, a start-up he founded, “aims to commercialize the computational microscopy.” Commercialization may give his and similar innovations a greater reach and applicability.

Pfizer Announces 500 Millionth Trachoma Treatment

Trachoma_TreatmentAccording to the International Trachoma Initiative (ITI), trachoma remains the world’s leading infectious cause of blindness. Pfizer Inc., along with several partners has been working to provide critical trachoma treatment, particularly for patients in developing countries.

What is Trachoma?

Trachoma is an infectious disease caused by bacteria. It is spread through contact with eye discharge from an infected person – via hands, towels, sheets and in some cases, eye-seeking flies. The infection thrives in areas with poor sanitation and limited access to water for personal hygiene.

Without treatment, trachoma develops into a condition called trichiasis. Trichiasis causes the upper eyelids to turn inwards and scrape the eyeball, a painful condition that eventually leads to blindness.

In 2014, the World Health Organization (WHO) estimated that 232 million people were at risk of developing trachoma. Studies indicate that trachoma is endemic in 51 countries with more than 80 percent of sufferers concentrated in 14 countries.

To help combat the spread of trachoma, Pfizer along with ITI and the International Coalition for Trachoma Control announced the corporation’s 500 millionth donation of the tablet Zithromax, a trachoma treatment antibiotic used in countries across Africa and Asia.

The partners are working together as part of an Alliance for the Global Elimination of Trachoma by 2020 (GET 2020) led by the WHO. The Alliance is an expansive collaboration of more than 100 governments, non-governmental organizations and private sector partners.

The SAFE Strategy

Together the group has implemented a WHO recommended strategy called SAFE:

Surgery to treat the blinding stage of the disease

Antibiotics to treat infection

Facial cleanliness to help reduce transmission, and

Environmental improvement including access to water and sanitation.

 

ITI pointed out trachoma was once endemic in Europe and the United States. Before the use of antibiotics, trachoma disappeared due to improved living standards.

Today, antibiotic treatment provides a short-term cure, especially when the whole community is treated. However, reinfection can occur, typically within six months if hygiene and the environment don’t improve. For this reason, it is essential that the full SAFE strategy is in place in trachoma-endemic communities.

Paul Emerson, the Director for ITI said, “Trachoma traditionally affects the people at the end of the road, they’re the forgotten people, they are people with a very little political voice. Because trachoma is a hidden disease it is very difficult for people to care. Well, we do care. And we want to reach all of those people.”

NetsforLife: Making Strides Toward Malaria Eradication

Mosquito_net_in_Subsaharan_AfricaAccording to the World Health Organization (WHO), approximately 3 billion people across the globe are at risk for contracting malaria. One-third of this group is considered to be at high risk and 90 percent of malaria deaths occur in Africa.

NetsforLife Steps In

NetsforLife is working to reduce the number of malaria deaths in Africa. Since its inception in 2005, this partnership of corporations, foundations, NGOs and faith-based organizations has distributed nearly 22 million mosquito nets in 17 malaria-endemic countries of sub-Saharan Africa.

However, the organization’s efforts to eradicate malaria extend beyond net distribution. According to its website, NetsforLife also ensures that communities receive adequate training on the value of these nets as well as “the right way to use and maintain them.”

Too often, mosquito nets have been used for fishing or as bridal veils instead of the vital purpose for which they were created.

In addition to educating communities on the proper use of nets, the organization also specifically targets remote areas that typically do not receive care from national healthcare systems.

NetsforLife calls on the help of local leaders and community volunteers or “malaria agents” to provide the necessary education and support to civilians.

Malaria Prevention is Key

According to the WHO, prevention is an important aspect of combatting malaria. The malaria parasite, Plasmodium, multiplies quickly, allowing it to build up resistance to malaria medicines. Mosquito nets and more specifically, insecticide-treated nets (ITNs), play a crucial role in prevention efforts.

While significant headway has already been made with the number of malaria cases declining to 214 million in 2015 from 262 million in 2000, there is still much work left to be done to eradicate the disease. To that end, the WHO launched “The Global Technical Strategy for Malaria, 2016 – 2030” which aims to reduce malaria incidence and mortality by 90 percent.

With over 100,000 volunteers, NetsforLife continues to do its part to help achieve these goals. So far, the organization has reached 41.7 million individuals and counting.

Global Partnership for the Global Health Security Agenda

Global_Health_Security_Agenda
The U.S. along with 30 countries has announced a commitment to achieving the targets of the Global Health Security Agenda (GHSA). Targets include responding to infectious disease threats and preventing epidemics.

The GHSA “seek[s] to accelerate progress toward a world that is safe and secure from infectious disease threats and to promote global health security as an international security priority,” GlobalHealth.gov said.

The Agenda was created in response to epidemic threats, such as ebola and seeks to promote global health and protect citizens around the world from life-threatening diseases.

The 30 countries that the U.S. has partnered with are: Bangladesh, Burkina Faso, Cambodia, Cameroon, Cote d’Ivoire, Democratic Republic of Congo, Ethiopia, Georgia, Ghana, Guinea, Haiti, India, Indonesia, Jordan, Kazakhstan, Kenya, Laos, Liberia, Mali, Mozambique, Pakistan, Peru, Rwanda, Senegal, Sierra Leone, Tanzania, Thailand, Uganda, Ukraine, and Vietnam, as well as the Caribbean Community.

The commitment includes a five-year country roadmap that will detail practical plans for the GHSA.

“These roadmaps are intended to enable a better understanding across sectors and assistance providers of the specific milestones, next steps, and gaps toward achieving capacity needed to prevent, detect, and respond to biological threats,” the White House said in a press release.

The countries involved seek to collaborate on a global issue that impacts millions of people in developing areas. Infrastructure, equipment and skilled personnel are some of the resources that the GHSA partnership plans to provide.

During this year’s G-7 Summit in Germany, G-7 leaders committed to collectively assisting at least 60 countries, including the countries of West Africa, over the next five years. The G-7 Health Ministers agreed to announce these countries by the end of this year according to the White House.

This collaboration provides a bright spot for the future. Health security is a huge issue today, as infectious diseases kill over 17 million people a year. At least 30 new diseases have emerged in the last 20 years, and they all require attention and research in order for cures to be discovered according to the World Health Organization.

Next year’s GHSA event will be hosted by the Netherlands and will highlight progress and continue to build momentum on these issues.

CFHI and Omni Med Tackle Preventable Diseases in Uganda

CFHI
Less than half of the population in Uganda has access to health care. In addition, the country suffers from a deficit of 1.5 million health workers. It is therefore not surprising that treatable diseases are the leading cause of death in Uganda.

The government created the Village Health Team program in 2001 to focus on the lack of health workers. The joint program “Community Health Workers & Global Health” will be based in Uganda’s Mukono District, 13 miles from the capital Kampala. The Child Family Health International organization offers global health education programs that “broaden students’ perspective on global health.”

Child Family Health International (CFHI) is partnering with Omni Med to expand health care capacity from rural to central Uganda. This expansion will improve Omni Med’s training and surveillance of Village Health Team and allow participants to assist the locally-led capacity building and quality assurance.

Omni Med began its work in Uganda in 2008 and has since trained over 1,200 community health workers and established protected water sources and cookstoves as well as distributing insecticide-treated nets. These teams include health educators in rural villages who make a big difference in the health of the world’s poorest people.

Village Health Teams are elected by local villagers and tasked with educating locals with preventative health information, referring sick people to health care centers and tracking health trends for Uganda’s Ministry of Health.

Child Family Health International Global Health Scholars, also known as participants, will assist the Village Health Teams in providing locals in rural Mukono with the best preventative tool: knowledge.

Scholars will accompany the teams on their home visits, train and maintain the team’s health knowledge by teaching in quarterly meetings and aiding in other Omni Med local activities.

“We believe strongly that it is not enough to feel good about what we do–we have to measure the impact we make, and then adjust our programs based on the data,” president and founder of Omni Med, Dr. Ed O’Neil Jr said.

Sierra Leone Declared Ebola-Free

No More Ebola in Sierra LeoneAfter nearly a two-year battle with Ebola, the World Health Organization (WHO) has announced that Sierra Leone is finally free of Ebola.

The country recently celebrated the milestone after almost 4,000 people died since the outbreak.

The WHO noted that 42 days have passed since the last confirmed patient was discharged on September 25 of this year. Anders Nordstrom, the Sierra Leone representative for WHO, revealed the positive news.

“WHO commends the government and people of Sierra Leone for the significant achievement of ending this Ebola outbreak,” Nordstrom said.

While the country has reached the 42-day benchmark, it still has to undergo a 90-day surveillance period.

Indeed, reaching the 42-days is a good reason to rejoice. However, it does not mean that Ebola in Sierra Leone is completely eradicated. Neighboring Liberia reached the 42-day goal in May, only to experience new cases before it was declared Ebola-free again.

Still, Sierra Leone remains optimistic with the news WHO has brought forth.

“We have prevailed over an evil virus. We persevered and we have overcome. We must not let down our guard,” said Sierra Leone President Ernest Bai Koroma.

The country will continue to take preventative measures to disable potentially new cases. Bodies will still continue to be swabbed and “safe burials will continue for all suspicious cases.”

It seems as though the disease has been prevented from spreading further. However, the people who had contracted the disease have ongoing health issues.

Juliet Spencer is considered by many to be one of the lucky ones. She contracted Ebola while taking care of her husband but was able to beat the virus. While she is happy that she is alive, she is still prevented from accomplishing tasks due to lingering complications.

“I feel good today that I have survived to see this day, witnessing this ceremony,” Spencer said. “My only regret is that I do not have a good health to carry on my business. I am unable to walk, I have joint pains and ear and eye problems.”

The 90-day surveillance period will be sure to test the country. However, the WHO and the people of Sierra Leone are confident that the disease will soon be eradicated. Nordstrom adds that the country could set an example for other countries looking to expunge Ebola.

“We now have a unique opportunity to support Sierra Leone and build a strong and resilient health system ready to detect and respond to the next outbreak of the disease or any other health threat,” Nordstrom said.

Company Partnerships Aim To Increase Access to Vaccines

Company Partnerships Aim To Increase Access to Vaccines Worldwide1.5 million children die from vaccine-preventable diseases annually. To combat these rising numbers, the Bill & Melinda Gates Foundation created a partnership with organizations to try a new approach and give children living in developing countries access to vaccines.

Since the development of the modern-day vaccine, millions of lives have been saved each year, becoming the most cost-effective health invention ever created.

While progress has been made, one in five children worldwide are not fully protected by the most basic vaccines.

With the help of a $750 million five-year pledge from the Bill & Melinda Foundation, the Global Alliance for Vaccines Immunization (GAVI) was created in January 2000.

The global public-private partnership’s goal is to save children’s lives and improve health through increasing vaccine access to the world’s poorest countries.

Since the inception of the alliance, the Bill & Melinda Foundation have committed $2.5 billion to GAVI.

“Investments in global immunization have yielded an extraordinary return,” said Julian Lob-Levvt, CEO of the GAVI Alliance. “The GAVI Alliance was founded just 10 years ago and has already saved 5 million lives by increasing access to immunization in the world’s poorest countries. The potential to make bigger strides in the coming decade is even more exciting.”

Through the global partnership, GAVI works with the World Health Organization (WHO), the World Bank, and UNICEF to deliver life-saving vaccines to developing countries.

By maximizing existing systems, the GAVI Alliance uses the following organizations so life-saving vaccines reach the poorest developing countries.

WHO: Since GAVI is not present on the ground, it works with WHO regional offices to decide where vaccines are desperately needed.

UNICEF: Using its supply division, UNICEF procures the vaccines while GAVI provides the funding. UNICEF procured $3.38 billion worth of supplies and services in 2014.

World Bank: The financial institution provides insight on supply and demand and plays a key role in innovative financing.

Since 2000, GAVI has contributed to the immunization of 500 million additional children.

Through continued partnerships, vaccines can prevent 264 million illnesses by 2020.

“We must make this the decade of vaccines,” said Bill Gates. “Vaccines already save and improve millions of lives in developing countries. Innovation will make it possible to save more children than ever before.”

Indian-American Physicians Take Reins of Indian Healthcare

Indian_HealthcareThe American Association of Physicians of Indian Origin (AAPI) will focus on women’s health and non-communicable diseases (NCDs) in India in its 10th Global Health Summit.

For almost a decade, the AAPI has gathered to contribute to the discussion of healthcare in India. This year, the focus will be on women’s health and non-communicable diseases, which plague 5.8 millions of Indians each year, according to the WHO.

Also included in this year’s summit will be a launch of the country’s first Trauma and Brain Injury Guidelines, reports ETHealthworld.

“This GHS promises to be one with the greatest impact and significant contributions towards harnessing the power of international Indian diaspora to bring the most innovative, efficient, cost effective healthcare solutions to India,” says AAPI.

This year’s summit will be held from Jan 1 to 3, 2016, in New Delhi.

The annual summit is not the only effort by the AAPI to improve Indian healthcare.

The organization also houses the Global Clinical Research & Trial Network (AAPI-GCRTN), which fosters collaboration on research and clinical trials; the Young Physician Section (AAPI-YPS), which educates and enhances the careers of young physicians; and the Charitable Foundation (AAPI-CF), which serves the poor in remote areas of India and the U.S.

The AAPI and its contributions to health in India serve as an example of the country’s growing interest in health and poverty, as well as its growing resources.

The Government of India has made tremendous progress recently, especially in commitment to pressing issues concerning the poor members of its population.

At the beginning of this year, India became the first country to adapt the Global Monitoring Framework on NCDs. In line with the WHO’s Global action plan for the prevention and control of NCDs 2013-2020, the framework’s targets are aimed at reducing the number of global premature deaths from NCDs by 25 percent by 2025, says the WHO.

India is paving the way for developing countries’ healthcare, and this summit will provide solutions for multiple healthcare problems that can be applied to other areas.

The Global Burden of Disease: Bringing Data to the People

Global Burden of DiseaseChris Murray, a professor of global health at the University of Washington Institute for Health Metrics and Evaluation, wanted to understand one simple question, “Why do people get sick and die?” To get the answer, he created a comprehensive database known as the Global Burden of Disease (GBD).

The tool is incredibly useful to policymakers and health care providers whose mission is to keep people healthy. Health is affected by a variety of factors including one’s demographics. Where someone lives play a role in his or her vulnerability to certain health risks; some countries experience higher rates of heart disease due to cultural dietary influences while others lose children at early ages because they do not have access to necessary vaccinations.

In order to effectively address health issues in a given country, there needs to be a clear picture of what the biggest health culprits are. While data that could help paint that picture has existed for years, it has been scattered among researchers, hospitals and governments, making it inaccessible and consequently less useful.

Murray created the GBD data collection to provide information to health workers, policymakers and the general public. It is the largest effort to measure epidemiological levels and health trends globally and contains the collected and analyzed data of more than 1,000 researchers in more than 100 countries.

The GBD is open to everyone and contains a visualization of data that allows for greater contextualization of what has been collected and observed. Experts from around the world have collaborated and continue to update the database to ensure it stays as accurate as possible.

In the 2013 systematic analysis for the Global Burden of Disease, researchers found that since 1990 the global life expectancy for both sexes has increased from 65.3 years to 71.5 years. However, an individual’s life expectancy and the likely cause of death differs based on where he or she lives and the economic status of his or her home country, which understandably plays a considerable role in the individual’s health.

For instance, while there have been reductions in the number of child deaths attributed to diarrhea, lower respiratory tract infections and neonatal causes in low-income regions, these health complications are still the leading cause of death in children younger than 5 years and are more prominent in poor countries compared to wealthy countries.

The GBD delivers information to the hands of people who can provide solutions. It allows health care workers to pinpoint the problem in order to begin addressing it. If governments know their citizens are vulnerable to certain health risks they can work toward identifying the causes and implementing solutions. There has always been power in knowledge, and the GBD allows for the consolidation of knowledge, thereby increasing its untapped power.

Syrian Conflict: Typhoid Outbreak Among Palestinian Refugees

typhoid_outbreak
The United Nations (U.N.) is calling for access to Yarmouk, a Palestinian refugee camp in the outskirts of Damascus, due to the increasing evidence of a typhoid outbreak. As of Sept. 20, a total of 90 cases has been reported.

The UN Relief and Works Agency (UNRWA) discovered the outbreak in August among Palestinian refugees outside Syria’s capital after conducting more than 500 medical exams.

The agency was able to gain access to one of the areas affected and established a mobile health point, which provides limited health care, water, sanitation and hygiene supplies, according to a UNRWA spokesperson.

Before the Syrian war began in 2011, there were 160,000 Palestinians in the Yarmouk camp, many of which were employed.

In late March of 2015 when the Islamic State entered the camp, there were 18,000 refugees. Since then, several thousand have fled and the U.N. has no access to the camp. ISIL left days later, but they still have a heavy presence on the al-Nursa Front.

Access has been blocked by the government as a result of clashes with rebels in December 2012. In addition, the government controls the entrance to the camp and sets limits on food, medicine and other humanitarian supplies that enter, claims the Jafra Foundation.

The organization adds that people are trapped inside with very little resources and estimates that there are about 5,000 to 8,000 people left within Yarmouk.

Other affected areas of the typhoid outbreak are Yalda, Babila and Beit Saham.

UNRWA’s $15 million Syria Crisis Program has only gotten 30.8 percent of the fund it needs for this year. The current situation is so dire that 95 percent of Palestinian refugees depend on UNRWA for their daily need of water, food and health care.

Additional help in priority intervention includes cash assistance, which can help up to 470,000 Palestinian refugees. There is still additional funding needed for critical non-food items such as blankets, mattresses and hygiene kits.

Typhoid is a life-threatening illness caused by bacteria in Salmonella typhi and spread by eating contaminated food and drinking contaminated water, according to the U.S. Centers for Disease Control and Prevention.

The disease can be treated with antibiotics but can be fatal in some cases. UNRWA is administering antibiotics, giving out water purifying tablets and educating the population.
