"These drugs are potentially harmful when taken for long durations, yet little has been known until now about the length of time osteoporosis patients should go without treatment for this debilitating condition," said Pauline Camacho, MD, study investigator and director of the Loyola University Osteoporosis and Metabolic Bone Disease Center. "Our study demonstrated that bones can remain stable for a number of years after these drugs are discontinued."
Doctors recommend that patients take drug holidays from bisphosphonates after four to five years. These drugs continue to stabilize bones and reduce the risk for bone loss after treatment ceases.
The study's goal was to identify the optimal drug holiday length after prolonged use of bisphosphonates based on changes in bone mineral density and bone loss. The study evaluated 139 patients (123 females, 16 males) with osteoporosis and osteopenia, the precursor to the disease. Patients took a bisphosphonate an average of 6.8 years before beginning a drug holiday from 2005 to 2010. Over three years, five fractures occurred, but bone mineral density did not change significantly. However, bone loss did start to increase at six months. The type of bisphosphonate and the duration of treatment did not affect bone mineral density.
"While further research is needed to adequately assess the optimal duration of the drug holiday, we do know that patients can relatively safely discontinue their treatment for at least three years," Dr. Camacho said. "However, patients who fracture during their drug holiday should notify their physician right away so osteoporosis therapy can be resumed. Patients also should continue to see their physician to regularly monitor their bone health."
Lauren Myers, a second-year medical student at Loyola University Chicago Stritch School of Medicine, and Jim Sinacore, PhD, associate professor of preventive medicine and epidemiology at Stritch, also were study investigators.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
