Hepatitis B accounts for 40 percent of 'missing' Asian women
November 09, 2005In a groundbreaking, sure-to-be-controversial new study, Emily Oster (a graduate student in economics at Harvard University) argues that excess female mortality, such as infanticide, may not be the only cause of uncommonly high male to female ratios in many Asian countries. It has long been observed that the relative number of males is higher in certain Asian countries than in the West, where it is close to unity. A number of authors have suggested that this imbalance reflects neglect of female children and poor conditions for women and, as a result, have argued that as many as 100 million women are "missing."
However, in the forthcoming issue of the Journal of Political Economy, Oster proposes an explanation for some of the observed over-representation of males: the hepatitis B virus. She presents new evidence, consistent with existing scientific literature, that carriers of the hepatitis B virus are 1.5 times more likely to have a male child. This evidence includes both cross-country analyses and natural experimentation based on recent vaccination campaigns. In addition, hepatitis B is common in many Asian countries, particularly China, where some 10 to 15 percent of the population is infected.
Using data on viral prevalence by country as well as estimates of the effect of hepatitis on birth sex, Oster concludes that hepatitis B can account for about 45 percent of the "missing women" - or, more specifically, for as many as 50 percent of the "missing women" in Egypt and West Asia; under 20 percent in Bangladesh, India, Pakistan and Nepal; and around 75 percent of the "missing women" in China.

Hepatitis B Current Events and Hepatitis B News RSSIs hepatitis B virus genotype C independently associated with cirrhosis?
Hepatitis B virus (HBV) genotypes have distinct geographical distributions, and have been shown to differ with regard to clinical outcome and prognosis.
Virus-like particle vaccine protects monkeys from chikungunya virus
An experimental vaccine developed using non-infectious virus-like particles (VLP) has protected macaques and mice against chikungunya virus, a mosquito-borne pathogen that has infected millions of people in Africa and Asia and causes debilitating pain, researchers at the National Institutes of Health have found.
Prognosis of intrahepatic cholangiocarcinoma
Incidence of intrahepatic cholangiocarcinoma (ICC) is increasing worldwide and its prognosis is very poor. Thus, further studies on its clinical characteristics for early detection and on surgical treatment for better prognosis are urgently needed.
IOM report recommends steps to tackle hepatitis B and C
Stepped-up vaccination requirements, a boost in resources for prevention and treatment, and a public awareness campaign similar to the effort that dispelled the stigma of HIV/AIDS are needed to curb the health threats posed by hepatitis B and hepatitis C, says a new report from the Institute of Medicine.
UCLA researchers demonstrate that stem cells can be engineered to kill HIV
Researchers from the UCLA AIDS Institute and colleagues have for the first time demonstrated that human blood stem cells can be engineered into cells that can target and kill HIV-infected cells - a process that potentially could be used against a range of chronic viral diseases.
Toward explaining why hepatitis B hits men harder than women
Scientists in China are reporting discovery of unusual liver proteins, found only in males, that may help explain the long-standing mystery of why the hepatitis B virus (HBV) sexually discriminates -- hitting men harder than women.
Hepatitis B does not increase risk for pancreatic cancer
A Henry Ford Hospital study found that hepatitis B does not increase the risk for pancreatic cancer - and that only age is a contributing factor.
Researchers prolong the plasma half-life of biopharmaceutical proteins
Many biopharmaceuticals comprise small proteins that are quickly eliminated from the body. Scientists at the Technische Universitaet Muenchen (TUM) combine such small proteins with a kind of molecular balloon that swells and thus prolongs the half-life of the proteins in the body.
Penn State College of Medicine research isolates liver cancer stem cells prior to tumor formation
Penn State College of Medicine researchers, in collaboration with colleagues at the University of Southern California, have taken an important step in understanding the role of stem cells in development of liver cancer.
New 'adjuvant' could hold future of vaccine development
Scientists at Oregon State University have developed a new "adjuvant" that could allow the creation of important new vaccines, possibly become a universal vaccine carrier and help medical experts tackle many diseases more effectively.

The First Year---Hepatitis B: An Essential Guide for the Newly Diagnosed by William Finley Green (Author), M.D. Hari Conjeevaram M.D. (Foreword) Hepatitis B is one of the most preventable medical conditions due to the availability of a hepatitis B vaccine, yet an estimated 100,000 people in the U.S. are infected each year, and 6,000 die from complications. When William Finley Green was diagnosed with hep B in 1993, he decided to be proactive in his quest to understand and manage his illness—by reading medical and scientific books and journals, talking with doctors, and networking with other people who have hepatitis B. He now shares his experience and knowledge with everyone who has been newly diagnosed. As a "patient-expert" on hep B, Green walks you step-by-step through everything you need to do and learn each day of your first week after diagnosis, each subsequent week of the first month, and the following eleven months of... |

Living with Hepatitis B: A Survivor's Guide by Gregory T. Everson (Author), Hedy Weinberg (Author), Steve Bingham (Author) A new book from the authors of the bestselling Living with Hepatitis C. Chronic hepatitis B, a condition that currently affects 1.25 to 1.5 million Americans, is a serious progressive disease that can lead to cirrhosis, liver cancer, the need for liver transplantation and death. According to the Centers for Disease Control, more than 200,000 Americans of all ages are infected each year with the hepatitis B virus (HBV). Sufferers of acute hepatitis B can become jaundiced, severely fatigued and too ill to work. Although most recover, some will experience acute liver failure, need emergent liver transplantation or die. Experts estimate that up to 10 percent of infected adults and 25 percent of infected children under the age of five will develop chronic hepatitis B. Now the team that wrote... |

Hepatitis B: The Hunt for a Killer Virus by Baruch S. Blumberg (Author) About 375 million people are infected with the hepatitis B virus. It has killed more people than AIDS and also causes millions of cases of liver cancer. The discovery of this deadly virus and the vaccine against it--a vaccine that is sharply decreasing the infection rate worldwide and is probably the first effective cancer vaccine--was one of the great triumphs of twentieth-century medicine. And it almost didn't happen. With wit and insight, this scientific memoir and story of discovery describes how Baruch Blumberg and a team of researchers found a virus they were not looking for and created a vaccine for a disease they previously knew little about--work that took the author around the world and won him the Nobel Prize. Blumberg and his collaborators were investigating... |

Hepatitis and Liver Cancer: A National Strategy for Prevention and Control of Hepatitis B and C by Committee on the Prevention and Control of Viral Hepatitis Infection (Author), Institute of Medicine (Author) The global epidemic of hepatitis B and C is a serious public health problem. Hepatitis B and C are the major causes of chronic liver disease and liver cancer in the world. In the next 10 years, 150,000 people in the United States will die from liver disease or liver cancer associated with chronic hepatitis B virus (HBV) or hepatitis C virus (HCV) infections. Today, between 800,000 and 1.4 million people in the United States have chronic hepatitis B and between 2.7 and 3.9 million have chronic hepatitis C. People most at risk for hepatitis B and C often are the least likely to have access to medical services. Reducing the rates of illness and death associated with these diseases will require greater awareness and knowledge among health care workers, improved identification of at-risk... |
