There is a need for trials on the effects of food aid products for children with moderate acute malnutrition, to identify how best to restore body tissues and function. The choice of control intervention is a major challenge, with both ethical and scientific implications. While randomized trials are needed, special designs, such as cluster-randomized, stepped-wedged or factorial designs may off...

Proof of principle that molecularly targeted therapy is a valid therapeutic approach for squamous cell carcinoma of the head and neck (SCCHN) has emerged with epidermal growth factor receptor targeting agents. Other interesting targets, such as Src, insulin-like growth factor 1 receptor, and the proteasome, have been shown in vitro to play key roles in SCCHN, and their inhibition is currently b...

Based on a strong rationale for anti-VEGF (vascular endothelial growth factor) treatment in breast cancer and promising preclinical data, great hopes have been placed on the anti-VEGF antibody bevacizumab. Clinical trials, however, reported conflicting results. In metastatic human epidermal growth factor receptor 2(HER2)-negative breast cancer, the addition of bevacizumab to standard chemothera...

Src, a membrane-associated nonreceptor tyrosine kinase, plays a crucial role in the coordination and facilitation of cell-signaling pathways controlling a wide range of cellular functions, including growth, survival, invasion, adhesion, and migration. Deregulation and increased activity of Src has been observed in multiple human malignancies, prompting the development of specific inhibitors of ...

The Forest Biology Research Cooperative recently established a series of loblolly pine clonal trials known as CCLONES (Comparing Clonal Lines on Experimental Sites). There are three primary levels of genetic structure in this study (parental, full-sib family, clone) that strengthen the power of CCLONES for examining genetic mechanisms and interactions with cultural treatments and locations. A f...

PURPOSE In solid tumors such as prostate cancer, novel paradigms are needed to assess therapeutic efficacy. We utilized a method estimating tumor growth and regression rate constants from serial PSA measurements, and assessed its potential in patients with metastatic castration resistant prostate carcinoma (mCRPC). EXPERIMENTAL DESIGN Patients were enrolled in five phase II studies, including...

Evidence-based medicine is a redundant term to the extent that doctors have always claimed they practiced medicine on the basis of evidence. They have, however, disagreed about what exactly constitutes legitimate evidence and how to synthesize the totality of evidence in a way that supports clinical action. Despite claims to the contrary, little progress has been made in solving this hard probl...
