(Press-News.org) Standardized screening rule for TB in people living with HIV in low income settings
In 2009, 1.7 million people died from TB— which translates to 4700 deaths a day—including 380, 000 people living with HIV. TB remains the most common cause of death in people living with HIV. This week in PLoS Medicine, Haileyesus Getahun (WHO) and colleagues report the development of a simple, standardized tuberculosis (TB) screening rule for resource-constrained settings, to identify people living with HIV who need further investigation for TB disease. The results of this study, which included an individual participant data meta-analysis, suggest that in such settings, the absence of current cough, fever, night sweats, and weight loss (all inclusive) can identify those people living with HIV who have a low probability of having TB disease. Furthermore, any one of these symptoms can be used in resource-constrained settings to identify people living with HIV who are in need of further diagnostic assessment for TB.

A new method to correct mortality rate biases in HIV treatment programs
2011-01-19
HIV treatment programs in sub-Saharan Africa should routinely report mortality rates among patients who remain in the programs and those patients lost to follow-up, according to a study by Matthias Egger and colleagues from the International Epidemiologic Databases to Evaluate AIDS in East Africa, Western Africa, and Southern Africa that is published in this week's PLoS Medicine. As a substantial proportion of patients in HIV treatment programs are lost to follow-up, mortality estimates for patients in these programs can be severely underestimated, so this bias needs to ...
Little evidence to support most eHealth technologies, such as electronic patient records
2011-01-19
Despite the wide endorsement of and support for eHealth technologies, such as electronic patient records and e-prescribing, the scientific basis of its benefits—which are repeatedly made and often uncritically accepted—remains to be firmly established.
Furthermore, even for the eHealth technologies that have proven to be successful, there is little evidence to show that such tools would continue to be successful beyond the contexts in which they were originally developed. These are the key findings of a study by Aziz Sheikh (University of Edinburgh, Edinburgh, Scotland) ...
Statins: Benefits questionable in low-risk patients
2011-01-19
There is not enough evidence to recommend the widespread use of statins in people with no previous history of heart disease, according to a new Cochrane Systematic Review. Researchers say statins should be prescribed with caution in those at low risk of cardiovascular disease (CVD).
CVD is the most common cause of death, accounting for nearly a third of all deaths worldwide. Cholesterol-lowering statins are first line treatments for heart patients and the benefits are well established. However, there is less evidence that statins are beneficial for preventing heart problems ...
Drug used to treat heavy periods will stop trauma patients bleeding to death
2011-01-19
Tranexamic acid (TXA), a drug used to treat heavy menstrual periods, could save the lives of tens of thousands of bleeding accident victims each year and reduce combat deaths, say Cochrane researchers. The researchers carried out a systematic review of trials examining the effectiveness of tranexamic acid (TXA) in patients with bleeding after severe injury.
TXA is an inexpensive drug that reduces clot breakdown. It has been used for many years to reduce heavy menstrual bleeding and is often given during planned surgery to reduce the need for blood transfusion. However, ...
Antioxidants may improve chances of conceiving in male subfertility
2011-01-19
Antioxidant supplements may benefit couples who have difficulty conceiving naturally, according to a new systematic review published today in The Cochrane Library. The review provides evidence from a small number of trials that suggest the partners of men who take antioxidants are more likely to become pregnant.
Male subfertility affects one in 20 men. Chemicals called reactive oxygen species (ROS) are said to cause damage to cells, and in particular sperm cells, which may result in lowered sperm counts and interfere with their ability to fertilise eggs. Antioxidants ...
Making health information technology more patient-centered
2011-01-19
RICHMOND, Va. (Jan. 19, 2011) – Personal health records have great potential to help patients manage their health, but technology needs to be designed with the patient in mind – which means doing more than helping patients access health information, according to an editorial by two Virginia Commonwealth University family medicine physicians published in the Jan.19 issue of the Journal of the American Medical Association.
In the editorial, Alexander Krist, M.D., M.P.H., associate professor in the Department of Family Medicine in the VCU School of Medicine, together with ...
Eating more fruit and vegetables is linked to a lower risk of dying from ischemic heart disease
2011-01-19
A European study investigating the links between diet and disease has found that people who consume more fruit and vegetables have a lower risk of dying from ischaemic heart disease – the most common form of heart disease and one of the leading causes of death in Europe. However, the authors point out that a higher fruit and vegetable intake occurs among people with other healthy eating habits and lifestyles, and that these factors could also be associated with the lower risk of dying from IHD. The study is published online today (Wednesday 19 January) in the European Heart ...
Korean researchers reveal new sea defense model
2011-01-19
Los Angeles, CA (January 18, 2010) - Military tension between North Korea and the Republic of Korea (South Korea) extends to areas of the Yellow Sea. Now defence experts based in the Republic of Korea have devised improved methods to model underwater warfare, which they believe can aid future decisions about weapons and defence purchases. The details appear today in the Journal of Defense Modeling and Simulation, published by SAGE.
The researchers based at the Korea Advanced Institute of Science and Technology (KAIST) and Seowon University, both in the Republic of Korea, ...

Weizmann Institute scientists discover: Antioxidants cause fertility problems in females
2011-01-19
Antioxidants are sold over the counter everywhere. They're added to food, drink and face cream. But according to Prof. Nava Dekel of the Biological Regulation Department, we still don't have a complete understanding of how they act in our bodies. New research by Dekel and her team, recently published in the Proceedings of the National Academy of Sciences USA (PNAS), has revealed a possible unexpected side effect of antioxidants: They might cause fertility problems in females.
Common antioxidants include vitamins C and E. These work by eliminating molecules called reactive ...
