Despite growth reports, Africa mired in poverty

Oct. 1, 2013 — Despite continued reports of economic growth in Africa, much of the continent remains wracked by poverty, with roughly one in five citizens saying they frequently lack food, clean water and medical care, according to the largest survey of African citizens.

This suggests the growth is not trickling down to the poorest citizens or that actual growth rates are inflated, said Carolyn Logan, assistant professor of political science at Michigan State University and deputy director of the survey, called the Afrobarometer.

"The survey results show there is a disconnect between reported growth and the persistence -- in both frequency and severity -- of poverty among ordinary citizens," Logan said. "It's evident that African governments need to focus as much attention on poverty reduction efforts as they are on growing their economies."

The fifth round of the Afrobarometer, which comes out every several years, was released today in Johannesburg. Thirty-four countries were surveyed -- up from 20 countries during the last round of surveys in 2008-9 -- making it the most comprehensive look at life in Africa since the Afrobarometer was started in 1999.

The release of today's findings on poverty and economic conditions is the first of seven release events in African cities up through Dec. 12. Future topics include democracy, corruption and Internet usage.

According to the current findings, 17 percent of Africans say they frequently go without food, 22 percent lack clean water on a regular basis, and 20 percent often go without medical care. About 50 percent do without these necessities at least occasionally. The problem is particularly striking in West Africa and East Africa, and less so in the northern and southern regions of the continent.

In addition, 53 percent of Africans rated their national economy negatively. And 38 percent said their national economy has gotten worse in the past year.

Moreover, Africans give their governments failing marks for economic management. Fifty-six percent say they are doing a bad job of managing the economy and even higher numbers rate them poorly for improving the living standards of the poor (69 percent), creating jobs (71 percent) and narrowing income gaps (76 percent).

The findings come despite the fact that Africa's gross domestic product grew by an average of 4.8 percent between 2002 and 2011, making Africa a new darling of portfolio investors and prompting The Economist magazine to tag Africa as "The Hopeful Continent."

The Afrobarometer is an independent, nonpartisan research project co-founded by Michael Bratton, University Distinguished Professor at MSU. Bratton currently serves as senior adviser on the project.

Core partners of the survey include the Center for Democratic Development in Ghana; the Institute for Justice and Reconciliation in South Africa; the Institute for Empirical Research in Political Economy in the Republic of Benin; and the Institute for Development Studies at the University of Nairobi in Kenya.

Despite higher survival, brachytherapy to treat cervical cancer declines in US

Sep. 11, 2013 — A study by researchers at Brigham and Women's Hospital (BWH) found that brachytherapy treatment was associated with better cause-specific survival and overall survival in women with cervical cancer. The population-based analysis also revealed geographic disparities and decline in brachytherapy treatment in the United States. Brachytherapy is a type of cancer treatment in which radioactive implants are inserted directly into the tissue near the tumor site.

The study is published in the September 2013 issue of The International Journal of Radiation Oncology.

The researchers used the Surveillance, Epidemiology, and End Results (SEER) Database to identify 7,359 patients with advanced stage cervical cancer treated with external beam radiation therapy (EBRT) between 1988 and 2009. (The 18 SEER population-based registries cover approximately 28 percent of the US population and include Connecticut, New Jersey, Metropolitan Detroit, Iowa, New Mexico, Hawaii, Seattle, Utah, Alaska, San Francisco-Oakland, San Jose-Monterey, Los Angeles, Greater California, Kentucky, Louisiana, Metropolitan Atlanta, Rural Georgia, and Greater Georgia. The registries collect information about patient and tumor characteristics and first course of cancer-directed treatment.)

Of the 7,359 patients identified, the researchers found that 63 percent of these women received brachytherapy in combination with EBRT, and 37 percent received EBRT alone. Factors associated with higher odds of brachytherapy use included younger age, being married, earlier years of diagnosis, earlier stage and certain SEER regions.

Moreover, brachytherapy usage rate decreased from 83 percent in 1988 to 58 percent in 2009. There was a sharp decline from 43 percent to 23 percent in 2003. The researchers noted that the decline may be related to the decreasing incidence of cervical cancer and increased adoption of alternative treatment techniques, such as intensity modulated radiation therapy (IMRT) and stereotactic body radiation therapy (SBRT).

In terms of patient survival, brachytherapy was associated with a higher four-year cause-specific survival (64.3 percent vs. 51.5 percent) and overall survival (58.2 percent vs. 46.2 percent) compared to EBRT alone. Brachytherapy treatment was also independently associated with better cause-specific survival and overall survival.

"The shift away from brachytherapy is concerning, and has directly lowered the survival rates of cervical cancer patients," said Akila Viswanathan, MD, MPH, director of BWH Gynecologic Radiation Oncology, senior study author. "High-quality brachytherapy must continue to be used, ideally with image-guidance, to maximize survival and minimize toxicity."

Brachytherapy is an important component of treatment that escalates the dose of radiation to the primary tumor while minimizing the dose to critical organs at risk. The standard treatment of locally advanced cervical cancer is EBRT with concurrent chemotherapy, followed by brachytherapy.
