Night shifts impair surgical dexterity
One night on call in a surgical department affects a surgeon's ability to perform laparoscopy (examination of the interior of the abdomen using a specialised viewing instrument), finds a study in this week's BMJ.

Genetic diagnosis 'will have few social consequences'
Using preimplantation genetic diagnosis (PGD) to choose a stem cell donor is unlikely to cause harm to anyone and is likely to be beneficial to some, suggest researchers in this week's BMJ.

Measures needed to reduce bloodborne infections in Irish prisons
There is an urgent need for increased infection control and harm reduction measures to reduce the transmission of hepatitis B and C viruses, and HIV in Irish prisons, concludes a study in this week's BMJ.

'Wait and see' policy' suggested for women with abnormal cervical smears in presence of high-risk human papillomavirus
Women with abnormal cervical smears (mild to moderate dyskaryosis) and who are positive for the high-risk form of human papillomavirus (HR-HPV) should not be treated for at least 6 months after cytological screening to see if the virus disappears, suggest authors of a research letter in this week's issue of THE LANCET.

In groundbreaking research, Yale and Salk Institute scientists reveal the structure of a key component that makes cells move
Researchers at Yale and the Salk Institute have determined the structure of a set of proteins called the Arp2/3 complex that helps cells move, paving the way for understanding how cells find bacteria and protect against infections.

Depression increases risk of cardiac events after coronary artery bypass surgery
A study in this week's issue of THE LANCET highlights how depression is an important independent risk factor for cardiac events after coronary artery bypass graft (CABG) surgery.

Study: 3 percent of N.C. drivers on cell phones at any given time
Overall, only 3.1 percent of North Carolinians are talking on cell phones at any given time while driving, a surprising new University of North Carolina at Chapel Hill study shows.

Lancet study shows DiaPep277 arrests progression of Type 1 diabetes
Experimental drug DiaPep277 has been shown in a Phase II human clinical trial to arrest the progression of type 1 diabetes, prevent destruction of insulin-producing pancreatic cells, and reduce the need for injected insulin in newly diagnosed patients.

Israeli scientists block the progression of Type I diabetes
A team of researchers led by Prof. Irun Cohen of the Weizmann Institute of Science has developed a unique approach for halting the progression of Type I (juvenile or insulin-dependent) diabetes.

Early promise for prevention of Type 1 diabetes
A preliminary (phase II) study in this week's issue of THE LANCET suggests that injection of a specific peptide in patients with early type 1 diabetes could stop disease progression by preventing the destruction of insulin-producing ß -cells.

Early assessment predicts long-term efficacy of HIV-1 antiretroviral therapy
A study in this week's issue of THE LANCET highlights how very early (one week) assessment can reliably predict the long-term effectiveness of antiretroviral therapy for HIV-1.

New finding may help doctors prevent HIV drug resistance
A study by the NIAID and NCI shows the rate at which HIV disappears from the blood during the first week of antiretroviral therapy accurately predicts a drug regimen's long-term effectiveness in an individual.

New analysis in the Lancet shows promising results with investigational drug in treatment of debilitating hormone disease
Results of an analysis published in today's issue of The Lancet show that the investigational drug pegvisomant normalized concentrations of the hormone IGF-I in 97 percent of patients with acromegaly during 12 months of treatment in two open-label studies.

Forest management may mitigate global warming
A new study suggests that forest management may be used to restrain the increase of atmospheric carbon dioxide, a greenhouse gas.

New study provides mixed report card on informed consent to cancer clinical trials
While most cancer patients enrolled in clinical trials understand the primary purpose of the research, nearly one quarter of the participants do not realize that clinical trials are conducted mainly to benefit future patients, not themselves.

Concerns raised over policy to add folic acid to flour
A UK Department of Health committee has now recommended universal fortification of flour with folic acid to reduce the level of neural tube defects.

Scientists tackle international environmental problem - ballast water
A new research project aims to tackle a huge environmental problem which costs the worldwide economy billions of pounds each year and which scientists say is worse than an oil slick.

Scientists design molecules that mimic nanostructure of bone
Scientists at Northwestern University have become the first to design molecules that could lead to a breakthrough in bone repair.

Pre-eclampsia linked to heart disease later in life
Genetic factors that increase the risk of cardiovascular disease may also be linked to pre-eclampsia (a serious condition that can develop during the second half of a pregnancy), finds a study in this week's BMJ.

Stanford, UCSF researchers home in on key gene in multiple sclerosis progression
A critical gene, osteopontin, which is involved in the development of multiple sclerosis, has been identified by researchers at Stanford University Medical Center and the University of California San Francisco.
