LOS ANGELES, June 5 (Xinhua) -- A latest study has found no evidence that screening for ovarian cancer may reduce the risk of dying from the disease, it was reported on Sunday.Screening, however, does increase the likelihood of unnecessary invasive procedures, according to researchers at the University of Utah.The researchers presented their findings at an on-going meeting of the American Society of Clinical Oncology in Chicago, The Los Angeles Times said.Researchers studied 78,216 women, ages 55 to 74, who participated in the National Cancer Institute's Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial. Half of the women received the usual care from their OB-gyns, and half received a CA 125 screening every year for six years and an ultrasound every year for four years. They were then followed for a maximum of 12 years.The researchers observed 212 ovarian cancers in the screened group and 176 in the normal care group. There were 118 ovarian cancer deaths in the screened group and 100 in the normal care group. The differences were not statistically significant. Overall, there were 2,924 deaths from all causes in the screened group and 2,914 in the normal care group.But the researchers also observed that 3,285 women had false- positive diagnoses from the screening. Among those, 1,080 underwent surgery that included an oophorectomy (surgical removal of one or both ovaries). Fifteen percent of those who had surgery developed major complications as a result. Overall, 1,771 women in the screened group (7.7 percent) had an oophorectomy, compared with 1,304 in the normal care group (5.8 percent)."We conclude that annual screening for ovarian cancer ... does not reduce disease-specific mortality in women at average risk for ovarian cancer but does increase invasive medical procedures and associated harms," the researchers said in the study.New data presented at the meeting also showed that the widely used cancer drug Avastin can improve treatment of ovarian cancer, The Times said.About 21,880 American women are diagnosed with ovarian cancer each year and about 13,850 die from it, according to the American Cancer Society. Because it produces few symptoms, the disease is typically not diagnosed until it has become advanced and spread throughout the body. As a result, five-year survival is only about 30 percent, and the disease is one of the five most deadly cancers among women. Being able to detect the cancer at an earlier stage when it might be more curable could thus, theoretically, improve the survival rate.The tests most commonly used to detect ovarian cancer include a transvaginal ultrasound to look for tumor masses and a blood test that screens for increased levels of a tumor marker called CA 125.

He also said that China's track record of sharing knowledge with the World Bank was creating a "catalyst for consensus" and that placed the institutions in good stead to benefit from China's economic consistence."The Chinese policy mix includes a tool box of administrative measures ... In general, one of the lessons that the United States and others can learn (from China) is that to have supervisory policies for bank regulatory systems can be a useful part of the tool set."Aside from hinting that over-heating global real estate markets could benefit from China's regulatory tightening, Zoellick suggested if China moved to more market-exposed decision making, he hoped China's bank regulators would not step too far back."Over time China will be better served to move to more precise and market signals than more administration-based decisions. Over time China will want to move to more market based decisions ... but I don't want this to be interpreted that supervisors don't have to supervise," he said.

BEIJING, Sept. 14 (Xinhuanet) -- The U.S. Food and Drug Administration (FDA) on Monday announced a recall on a drug infusion pump of Medtronic, the Associated Press reported.The recalled drug pump was called "SynchroMed II", including models of 8637-20 and 8637-40, distributed between 2004 and July 2011.Drug infusion pump was used to deliver the drugs for patients to treat chronic pain, spasms as well as other conditions.The pumps' malfunction could put patients in the risk of either recurrent or withdrawal symptoms, which could be life-threatening, FDA warned.There were 55 reported cases and one death related to the drug withdrawal, among a total 139,653 SynchroMed II pump implants worldwide, FDA notified.The problem was due to a film within the pump's battery that could stop the therapy, FDA said.Medtronic, the U.S. medical technology company based in Minneapolis, is not recommending patients to remove the pumps, but instead, encourage patients to contact their doctor if they hear the device alarm.

BANJUL, June 24 (Xinhua) -- Deputies at the Gambian National Assembly (parliament) on Friday passed a new bill entitled the "Food Safety and Quality Bill 2011".Under the new act, food operators are obliged to ensure food safety, quality production, processing and distribution within the business under their control and that their products must satisfy the requirements and regulations as demanded.Submitting the motion before deputies, Vice President and Minister for Women Affairs Isatou Njie-Saidy warned that the well- being of "our citizenry is at stake.""Giving our continuous drive to place health care on top of our development agenda, we call on all and sundry to join the bandwagon in the implementation of this bill," she said.She told deputies that the bill and the establishment of the Gambia Food Safety and Quality Authority is consistent with the regulation worked out by the West African bloc ECOWAS on the health and safety of plants, animals and food in the region.The Gambia Food Safety and Quality Authority being established by this bill will be the sole national competent authority having unitary responsibility for food safety and quality, she declared."In order to achieve the general objectives of a high level of protection of human health and life, measures applied under this Act shall be based on risk assessment," she added.

NEW YORK, July 15 (Xinhua) -- A Gallup survey released on Friday found a total of 59 percent of Americans support a ban on smoking in all public places.The July 7-10 survey among 1,016 national adults showed a change in the public's attitude toward public smoking ban. In 2001, when Gallup first asked about a ban on public smoking, 39 percent were in favor, an attitude that stayed roughly the same through 2007.At the same time, the poll also found that fewer than two in 10 people supported the idea of making smoking totally illegal.According to the American Lung Association, 27 states plus the District of Columbia have passed comprehensive smoke-free laws. A New York City law bans smoking in virtually all public places, including outdoor plazas and beaches.
