Adjuvant Arthroscopy Does Not Improve the Functional Outcome of Volar Locking Plate for Distal Radius Fractures: A Randomized Clinical Trial.

Purpose: To evaluate the outcomes of adding arthroscopy to osteosynthesis of distal radius fractures (DRF) with volar locking plate (VLP), by Patient-Rated Wrist Evaluation (PRWE) 1 year after surgery.

Methods: In total, 186 functionally independent adult patients who met the inclusion criteria (DRF and a clinical decision for surgery with a VLP) were randomized to arthroscopic assistance or not. Primary outcome was PRWE questionnaire results 1 year after surgery.

Hedgehog Signalling Modulates Immune Response and Protects against Experimental Autoimmune Encephalomyelitis.

The Hedgehog (Hh) pathway is essential for the embryonic development and homeostatic maintenance of many adult tissues and organs. It has also been associated with some functions of the innate and adaptive immune system. However, its involvement in the immune response has not been well determined.

Clinical Relevance of +936 C>T and c.233C>T Polymorphisms in Chronic Lymphocytic Leukemia.

Angiogenesis process contributes to the pathogenesis of B-cell chronic lymphocytic leukemia (B-CLL) being the levels of VEGFA and bFGF higher in patients than in healthy controls. Our aim was to evaluate the implication of angiogenesis factors genetic variants in the predisposition to B-CLL and their association with clinical factors and survival. We performed a population-based case-control study in 224 Spanish B-CLL patients and 476 healthy randomly selected controls to evaluate susceptibility to developing B-CLL.

The Well-Being of the Elderly: Memory and Aging.

The world population increases every day as a consequence of the increase in life expectancy and longevity of humans. There are several factors analyzed in the different studies that have been developed on this topic. The research carried out in this field distinguishes biological, cultural, and cognitive factors; some of them describing similar results, while many others showed antagonistic results.

The miRNA-449 family mediates doxorubicin resistance in triple-negative breast cancer by regulating cell cycle factors.

The mechanisms of chemotherapy resistance in triple negative breast cancer remain unclear, and so, new molecules which might mediate this resistance could optimize treatment response. Here we analyzed the involvement of the miRNA-449 family in the response to doxorubicin. The cell viability, cell-cycle phases, and the expression of in silico target genes and proteins of sensitive/resistant triple negative breast cancer cell lines were evaluated in response to doxorubicin treatment and after gain/loss of miRNAs-449 function achieved by transient transfection.
