Early detection of the infection is important for successful treatment. But since the first symptoms resemble ordinary flu, a microbiologist must look at a drop of a patients blood under a microscope for a proper diagnosis. Scientists in Britain have now developed a smart phone attachment called Xrapid, that turns the phone into a 200-power microscope, while the attached app - based on facial recognition software - quickly detects the parasitic protozoa in the blood smear. Jean Viry-Babel is the CEO of IanXen, the company that developed the app. He says it is cheap and works on the spot. So we take a high-definition picture of a sample of blood. We separate the red blood cells from the rest - the white blood cells,...

The researchers looked at three types of B vitamins - B-6, B-12 and folic acid - and determined that the risk to a pregnancy was higher with B-12 and folic acid deficiencies and with deficiencies in more than one type of B vitamins. The researchers also found that women with high DDT and low B vitamin levels took nearly twice as long to conceive in the first place. The standard of care in many nations is to give an iron-folate supplement to women once they seek prenatal health care, which typically occurs between eight and 12 weeks of gestation, if at all. But that supplement is rarely taken prior to conception, meaning it likely comes too late to prevent early pregnancy loss. And unlike in the United States, where...

Every day for up to a year, researchers tested the urine of the women in the study, detecting their levels of hCG the hormone that signals conception. This approach allowed researchers to determine whether a woman was pregnant much earlier than she might normally find out, in the days over even weeks before she realized she'd missed a menstrual period. It also allowed the researchers to determine whether women had an early pregnancy loss (miscarried before six weeks of pregnancy). DDT and DDE (major degraded product of DDT) and B vitamin levels were measured in the women before conception. A 2003 study by Wang and her colleagues showed that one-third of all conceptions end before women even know they are pregnant....

"This is a very vulnerable period," she says. Among the 291 women ultimately included in the study, there were 385 conceptions, 31 percent of which were lost before six weeks. Women with high DDT levels and sufficient levels of vitamin B had a 42 percent greater chance of early miscarriage than women with lower DDT levels. But in those with high DDT levels and vitamin B deficiencies, women were twice as likely to suffer a miscarriage before six weeks of gestation. The researchers looked at three types of B vitamins - B-6, B-12 and folic acid - and determined that the risk to a pregnancy was higher with B-12 and folic acid deficiencies and with deficiencies in more than one type of B vitamins.

As word has got around about these problems, some people have opted not to take the medicine as directed, or at all. I dont know the right dose, and Ive heard different things, says Fatamata Kamara of Kroo Bay, a slum in the capital Freetown. I know it made some people very sick, and Im afraid to go to the hospital and get Ebola, she says. But Kamaras reluctance to take the malaria drug increases the likelihood of that very problem. Because malarial fevers are similar to Ebola fevers, anyone with a fever is told to check into a clinic to be tested. There, people with malaria wait hours or days for diagnosis beside others who may have Ebola.

The authors compared the current recommended therapy for uncomplicated malaria in children in Papua New Guinea, artemether-lumefantrine, with a different combination therapy, artemisinin-naphthoquine. Using a randomized, controlled trial study design including 186 children with Plasmodium falciparum infections and 47 children with Plasmodium vivax infections, the researchers found that artemisinin-naphthoquine was non-inferior to (no worse than) artemether-lumefantrine for treating Plasmodium falciparum (a difference of 2.2% [95% confidence interval ?3.0% to 8.4%] for reappearance of infection within 42 days) but was more effective for treating Plasmodium vivax (a difference 70.0% [95% confidence interval 40.9%-87.2%]...

ADVERTISEMENT ADVERTISEMENT Guinea's drop in reported malaria cases this year by as much as 40 percent is not good news, said Dr. Bernard Nahlen, deputy director of the U.S. President's Malaria Initiative. He said the decrease is likely because people are too scared to go to health facilities and are not getting treated for malaria. "It would be a major failure on the part of everybody involved to have a lot of people die from malaria in the midst of the Ebola epidemic," he said in a telephone interview. "I would be surprised if there were not an increase in unnecessary malaria deaths in the midst of all this, and a lot of those will be young children." Figures are always estimates in Guinea, where half the 12 million...

Ebola and malaria have many of the same symptoms, including fever, dizziness, head and muscle aches. Malaria is caused by bites from infected mosquitoes while Ebola can be contracted only from the body fluids of an infected victim hence doctors' fears of drawing blood to do malaria tests. People suffering malaria fear being quarantined in Ebola treatment centers and health centers not equipped to treat Ebola are turning away patients with Ebola-like symptoms, doctors said. WHO figures from Gueckedou show that of people coming in with fever in October, 24 percent who tested positive for Ebola also tested positive for malaria, and 33 percent of those who did not have Ebola tested positive for malaria an indication of...
