Malaria Deaths are Decreasing in Africa

Malaria Decline Africa Mosquito Bed Nets
Africa faces the world’s most dramatic public health crisis. Although polio is close to eradication, and more than half of African children have received the measles immunization, key public health issues continue throughout Africa.

Malaria is preventable and curable, yet it kills about 655,000 people worldwide every year. Malaria is transmitted through mosquitos infected with parasites, and it can also be passed to a growing fetus from an infected mother. Malaria causes fever, chills, muscle pain, and if not treated can result in death.

According to the Center for Disease Control (CDC), 91 percent of malaria-caused deaths occur in Africa. Moreover, 86 percent of malaria deaths globally are children. Malaria is a disease of poverty. The most vulnerable are children under five and pregnant women living in rural areas.

Malaria deaths decreased by 25 percent globally from 2000 to 2010. How was this achieved?

 

1. World Health Organization (WHO)

According to the WHO, 33 African countries have adopted artemisinin-based combination therapy as malaria treatment, which is the most effective antimalarial medicine. Other treatments include insecticide-treated nets, indoor residual spraying, and intermittent preventive treatment during pregnancy. In the WHO African region, malaria cases decreased by 50 percent between 2000 and 2008 due to these measures.

 

2. United Nations Children’s Fund (UNICEF)

From 2000 to 2012, UNICEF provided over 120 million Insecticide-Treated Nets (ITNs). During this time, children sleeping under ITNs increased from 2 percent to 39 percent. As malaria-infected mosquitos bite at night, the regular use of ITNs can reduce child mortality by 20 percent.

 

3. The Global Fund

Through funding from the Global Fund, 310 million mosquito nets and 181 million cutting-edge antimalarial treatments have been distributed.

 

4.  The President’s Malaria Initiative (PMI)

PMI is led by USAID under a U.S. Global Malaria Coordinator and jointly implemented with the Centers for Disease Control (CDC). PMI is one of the largest donors for malaria. Its goal is to half malaria for 70 percent of the at risk sub-Saharan population. PMI has chosen 19 focus countries. In Tanzania, PMI efforts, through the malaria control scale-up, have reduced all-cause child mortality (ACCM) by 10 deaths per 1,000 live births.

Through all these efforts over a million lives have been saved. Still a child dies every minute from malaria.

Widespread malaria is an obstacle to the development and growth of affected African countries and communities. For every $1 invested in malaria commodities, a $40 return can be expected in the form of productivity from healthier, better educated more productive working communities.

Is McGill University Doing “Asbestos” it Can?

mcgill_university
Asbestos, which has been mined for more than 4,000 years, was not largely distributed until the end of the 19th century. Today, armed with the knowledge about the dangers to human health that asbestos poses, production in the modern world has been brought to a halt. However, in many developing countries, particularly in Asia, many are surprised to hear that the use of asbestos has been increasing.

The world’s largest asbestos mine was the Jeffrey mine in the town of Asbestos, Quebec. Because of the preciousness of asbestos to the Quebecois economy, when results began to show the toxicity of asbestos, the Quebec Asbestos Mining Association (QAC) needed to find a solution preventing the stoppage of asbestos use. They turned to McGill University.

Professor J.C. McDonald, working for McGill’s Department of Epidemiology, was funded by a front organization set up by the QAC to research the effects of asbestos. His findings, using outdated and inaccurate techniques, demonstrated that exposure to chrysotile asbestos could give protection against cancer.

Despite the fact that no other scientist has been able to replicate McDonald’s data – even McDonald himself refuting his own findings, going so far as to admit that some of the data taken was thrown away until specific results were found – many companies continue to use his research to support the use of asbestos.

As such, every year, two million tons of asbestos are being put into homes and schools, ultimately causing a public health catastrophe to come.

Kathleen Ruff, founder of the human rights website RightonCanada.ca, and senior advisor on Human Rights of Rideau Institute was joined by Professor David Egilman of Brown University, who is the President of Global Health through Education, Training and Service (GHETS), a NGO dedicated to improving health in under-served communities around the world, at a conference on October 1st at McGill.

Here, Egilman and Ruff addressed McGill’s “internal review” on McDonald’s study, which Abraham Fuks, McGill’s research integrity officer, concluded Professor McDonald to be “a pioneer in the demonstration of health hazards of asbestos.”

Fuks states that while it is true that McDonald’s project was funded by the asbestos industry, there was no collusion between the university and the asbestos industry.

Egilman contends noting, “[McDonald’s team] threw data out because it gave them wrong results.” And when they finally had data that matched up to what they wanted to prove, Ruff points out that “the industry [then] went on a mission to developing countries to get them to use chrysotile asbestos.”

The problems associated with asbestos-related risks are manifold. The previous installation and further dismantling of asbestos abroad lacks proper regulation and legislation, with many companies not respecting safety and proper execution. Consequently, exposure increases the risk of lung cancer, mesothelioma, and nonmalignant lung and pleural disorders.

Countries with economic ties to asbestos, such as Russia, India and Brazil continue to use McDonald’s information to lobby for increased use. Without an independent review of the research conducted and a final nay-say of McDonald’s results, it will prove difficult to put a stop to these organizations.

What started as a good PR strategy back in the 1960s has now exploded into one of the main justifications of continued global asbestos use.

GHETS, founded in 2002, places emphasis on “grassroot partnerships, sustainability and the development of primary healthcare infrastructure.” In association with many major institutions, GHETS funds training of local doctors and distribution of seed grants to for local business start-ups.

RightonCanada, an advocacy campaign to put human rights back on Canada’s political agenda, believes that Canada, when refusing to recognize the human right to water, aid in sabotaging a U.N. Declaration on the Rights of Indigenous Peoples, and block action to control export to developing countries of asbestos, among other things, has consequently become “a human rights saboteur.”

Low Blood Oxygen? Phone Oximeter is the App

phone_oximeter
With over a million apps in the Google Play store and nearly that many in the App store, there’s an app for nearly everything–from locking your car doors, finding the perfect recipe for dinner, creating digital watercolor paintings, to monitoring your diet. Now there’s an app for measuring pulse oximetry, or the amount of oxygen in the blood. According to experts, over two-thirds of the six billion cell phone users in the world live in developing nations. The app, called Phone Oximeter, can aid health workers trying to diagnose pneumonia – particularly in children – and pre-eclampsia.

The Phone Oximeter was among ten innovations chosen by the UN and PATH to aid against deaths amongst women and children worldwide, especially deaths related to childbirth. Developed by Dr. Mark Ansermino and colleagues at the University of British Columbia, the device can be attached to a cellphone or tablet in order to measure pulse oximetry. The device can be attached either to the fingertip or earlobe. Reading the results of the Phone Oximeter is simple, according to Ansermino: “When you have got oxygen in your blood, it goes red and when you have not got oxygen in your blood, it goes blue. And that is why we get this tinge around our lips when it is cold because we do not have enough oxygen in the blood around your lips. But also when children get sick … we see the same blue color. So, what we do really is look at this light shining through the tissue and determine the bounds of this red to blue light, and from that we can tell how much of your blood has oxygen in it and how much does not.”

Other potential uses being explored for the Phone Oximeter include monitoring anesthesia in developing countries. Use of pulse oximetry in developed nations leads to significant decreases in the death rate. It detects low blood oxygen levels at the earliest symptoms and allows for a rapid response to the problems that arise thereafter. This can prevent brain damage and death. In the developing world, the death rate from anesthesia is still 100 to 1000 times higher than the rest of the world. As it continues to develop, the hope for the Phone Oximeter is that it would “demonstrate the potential for enhanced delivery of information from a pulse oximeter to enhance the safety of anesthesia care throughout the developing world.”

Designed to be easy to read and to aid healthcare workers at all levels, regardless of specialty, the Phone Oximeter is relatively inexpensive, expected to cost between $10 to $40.

Michael J. Fox: Race to Find Parkinson’s Disease Cure

Michael J Fox Back To The Future Marty McFly Parkinson's Disease Cure
Parkinson’s disease is a progressive degenerative disease of the central nervous system. The disease commonly affects the brain and motor functions. It causes difficulty and rigidity in simple motor functions and activities such as walking, sitting, thinking, and balancing. Often it occurs in older people, but some cases include people in their early forties. If the disease is left untreated, it can lead to more severe maladies such as dementia and immobility.

The disease often develops slowly and can go unnoticed. Initial symptoms include a noticeable tremor in just one hand, stiffness of the body, and slow movements. According to Mayo Clinic, during the early stages of the disease, patients may notice that the face shows little to no expression, and that their arms may not swing when walking. Other symptoms include impaired balance, speech changes, blurred vision, writing changes and an impaired sense of smell.  These symptoms can worsen over time. Although the disease can’t be cured, there is a wide array of medications that can help treat it.

Michael J. Fox, a world renowned actor, was diagnosed with Parkinson’s disease when he was just 37 years old. Since then, he has been advocating nationally and internationally for a cure. He predicted that he would find a cure by the time he was 50 years old. However, he is still far from his goal.

He is often praised for his advocacy towards a cure for the disease, and often helps report symptoms and side effects related to the disease. According to WebMD, the actor first reported a “rolling pin tremor on his right hand,” which was later followed by stiffness in his limbs and face. Today, Fox reports that the disease now affects the left hemisphere of his body. Michael J. Fox said he is in the “late-mild” stage of the disease.

Fox wanted to go public about his condition to raise public awareness and funding for Parkinson’s disease, WebMD reports. He has raised awareness via his foundation Web site, which is dedicated to fundraising and finding a cure for Parkinson’s disease. Fox’s foundation is also dedicated to finding innovative research for Parkinson’s Disease patients. Fox’s advocacy can be summarized with his powerful motto, “The cures we want aren’t going to fall from the sky. We have to get ladders and climb up and get them.”

Chaga Mushroom Might Be The Cure for HIV

chaga_mushroom
Could there be a cure for HIV? According to Russian researchers, the Chaga mushroom can “cure the Human Immunodeficiency Virus or HIV.” The Chaga mushroom is a small mushroom usually found in birch and other hardwood trees. It contains betulinic acid, which is considered a toxic substance to cancerous cells. It also has antiviral properties that are essential in the search for an HIV/AIDS cure.

The Chaga mushroom (or Inonutus obliquis) can be found in several regions around the world, most commonly Siberia and other regions in Eurasia. The Chaga mushroom is often characterized by its porous, dark appearance: often black-blue or purple. According to researchers, “strains of these mushrooms demonstrated low toxicity and strong antiviral effects against influenza, smallpox and HIV.” In addition, Siberian researchers at the Vector Institute have compared the Chaga mushroom to a variety of fungi growing in Siberia: 82 strains of 33 fungi and have determined that the Chaga mushroom has the strongest antiviral capacity.

Moreover, the Chaga mushroom usually grows in cool regions such as Russia, Korea, as well as other Eastern and Western European states. Scientists have found that the Chaga mushroom also grows in select parts of the United States and Canada.

The antiviral mushroom has been a constant subject in Russian folk medicine. The folk remedies use the mushroom to cure diseases such as cancer, cardiovascular diseases, and diabetes.

Despite its positive appeal as a potential cure for cancer and HIV/AIDS, the mushroom has not undergone official testing. However, it presents newfound hope for researchers and people diagnosed with these diseases. Research plans to investigate the mushroom’s potential benefits will be held sometime in 2015.

Health Leads & Clinton Global Initiative

Risa_Lavizzo_Mourey_Clinton_Global_Initiative
Risa Lavizzo-Mourey, President and CEO of the Robert Wood Johnson Foundation, spoke about Health Leads during a panel discussion on non-communicable diseases (NCD) at the Clinton Global Initiative on 24 September. Ms. Lavizzo-Mourey noted that important preventative measures for NCDs should include analyzing the living environments outside hospital walls in order to improve the quality of overall care people receive, which is what Health Leads specifically advocates and executes.

Health Leads’s mission statement reads, “to catalyze this health care system by connecting patients with the basic resources they need to be healthy…to champion quality care for all patients.” An example of this model is enabling doctors to prescribe basic resources like food and heat to their patients the same way the doctors would prescribe medicine or provide referrals. This whole-patient approach requires healthcare professionals to learn about the community environment and the living conditions of their patients when they leave their doctors’ offices.

The results of these inquiries enter the patient’s electronic record, which partner-hospitals can use to refer patients who lack basic resources to Health Leads. Through a systematic set of steps, the patient can carry the prescription to a Health Leads desk at the partner-hospital.

A Health Leads Advocate then works with the patient to connect her to the necessary community services that will help provide the basic resources the patient requires. Aid programs for basic resources may include additional health insurance coverage, access to food pantries and food assistance programs, discounts on gas and electric costs, job training, and childcare subsidies.

The last two steps require a follow-up from the Health Leads Advocate and updates to the clinic team from the patient. This symbiotic relationship is necessary to navigate any further challenges that may arise as a result of the previous steps. These challenges may include tracking down phone numbers, creating maps, finding transportation, and completing applications. Health Leads launched in 2010 and has since served over 23,000 patients.

In 2012, the program identified the top seven patient needs: education, utilities, housing, food, employment, income and benefits, and legal. To address these needs Health Leads trains a dedicated staff of program managers and Advocates whose sole design is to connect patients with the basic resources they require to get healthy.
