COLUMBUS, Ohio – Some hedge funds manipulate stock prices at the end of the month to improve the returns that they report to their investors, a new study suggests.

In a study of 10 years of hedge fund data, researchers found evidence that some funds run up prices on specific stocks they hold on the last day of the month and quarter – especially the last 20 minutes of trading – before they report their returns for the period. But the prices usually fall back the next day, after the abnormally large returns have already been reported to investors.

WINSTON-SALEM, N.C. – Dec. 10, 2012 – When you're postmenopausal and overweight, losing weight is a good thing, but gaining back just a few pounds may actually be detrimental to your cardiovascular health.

New research from Wake Forest Baptist Medical Center found that gaining weight back after intentional weight loss is associated with negative long-term effects on some cardiometabolic (CM) risk factors in postmenopausal women.

COLUMBUS, Ohio – A new study led by researchers at the Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC – James) shows that preparing older acute myeloid leukemia (AML) patients for bone marrow transplants with a reduced intensity conditioning regimen appears to be associated with higher rates of disease-free survival relative to the more typical treatments usually given to such patients. The study was presented at the 2012 American Society of Hematology (ASH) Annual Meeting in Atlanta, GA.

(ATLANTA, December 9, 2012) – Studies of stem cell biology and transplant approaches presented today at the 54th Annual Meeting of the American Society of Hematology (ASH) illustrate how the use of advanced modeling techniques is optimizing stem cells to treat patients with blood disorders, as well as the potential of enhanced treatment strategies to improve the success rate of hematopoietic stem cell (HSC) transplantation for these patients.

(ATLANTA, December 9, 2012) – Encouraging safety and efficacy data on novel and emerging therapies presented at the 54th Annual Meeting of the American Society of Hematology (ASH) signal an important step forward in the development of treatment strategies for patients with hard-to-treat leukemia, myeloma, and myelofibrosis.

A new drug for patients with acute myeloid leukemia (AML) marked by a specific type of genetic mutation has shown surprising promise in a Phase II clinical trial. In more than a third of participants, the leukemia was completely cleared from the bone marrow, and as a result, many of these patients were able to undergo potentially curative bone marrow transplants, according to investigators at the Johns Hopkins Kimmel Cancer Center and nine other academic medical centers around the world.

(ATLANTA, December 8, 2012) – Studies presented today at the 54th Annual Meeting of the American Society of Hematology (ASH) examine current treatment standards for patients with clotting disorders in an effort to improve outcomes. The studies evaluate long-held treatment standards and whether modifications in intensity and duration of therapy may offer equally effective outcomes while reducing toxicities and relapse rates.

(ATLANTA, December 8, 2012) –The promising investigational targeted therapy ibrutinib and its mechanism of silencing gene communication pathways critical to the development of cancer may be an effective way to combat chronic lymphocytic leukemia (CLL), according to studies presented today at the 54th Annual Meeting of the American Society of Hematology (ASH).

COLUMBUS, Ohio – Updated results from a Phase Ib/II clinical trial indicates that a novel therapeutic agent for chronic lymphocytic leukemia (CLL) is highly active and well tolerated in patients who have relapsed and are resistant to other therapy.

The agent, ibrutinib (PCI-32765), is the first drug designed to target Bruton's tyrosine kinase (BTK), a protein essential for CLL-cell survival and proliferation. CLL is the most common form of leukemia, with about 15,000 new cases annually in the U.S. About 4,400 Americans die of the disease each year.

Economic growth will rise to 3 percent in 2013 and 2014, while unemployment will drop to 7.3 percent by December of 2013, says New Jersey Institute of Technology Professor William V. Rapp, PhD, who told economists and others the good news last week at the annual outlook symposium sponsored by the Chicago Federal Reserve Bank.

Since the start of 2012, a new drug called rilpivirine has been available for adult patients infected with the human immunodeficiency virus type 1 (HIV-1). It is marketed by two different pharmaceutical companies, by one as a single agent (trade name Edurant®) and by the other as a fixed combination with other HIV drugs (trade name Eviplera®).

The health benefits of 'water clubs' in care homes for the elderly, where residents gather together regularly to drink water , owe as least as much to the social nature of the activity as to the value of drinking water itself, an investigation by psychologists has shown.

The study, funded by the Economic and Social Research Council (ESRC), supports other findings that interventions aimed at improving individuals' wellbeing and quality of life can be far more effective if they are carried out among groups of people in ways that generate a strong sense of group identity.

Antidepressants are the most widely used treatment for people with moderate to severe depression. However, up to two thirds of people with depression don't respond fully to this type of treatment. New findings, published in The Lancet, have shown cognitive behavioural therapy (CBT)*, provided in addition to usual care, can reduce symptoms of depression and help improve patients' quality of life.

A collaborative study conducted in Mexico by researchers from the West Virginia University-Charleston (US), Universidad Popular Autónoma del Estado de Puebla (México), Universidad de Chile and the Institute of Molecular Epidemiology of the Universidad Católica de la Santísima Concepción (Chile), revealed that opinion surveys used by researchers from the Guttmacher Institute overestimated figures of induced abortion in the Federal District of Mexico (Mexico DF) up to 10-fold.
