Women treated for breast cancer who are considering taking Hormone Replacement Therapy (HRT) should be cautious when using published research to inform their decision. An article published today in the journal Breast Cancer Research reveals that qualitative studies on the recurrence of breast cancer in breast cancer survivors undergoing HRT are unreliable.
There are two main types of research studies – qualitative and quantitative. Each type is used to answer different research questions. Dr Col, from Brown Medical School, USA, and colleagues found that all of the qualitative studies on the recurrence of breast cancer in patients taking HRT they looked at have “serious design features that could introduce selection, reporting and/or publication biases”.
These qualitative studies have concluded that there is no increased risk of the recurrence of breast cancer in patients taking HRT, but the authors of today’s study feel that this is not a reliable conclusion. Meanwhile, evidence from randomized controlled trials - a type of quantitative study – suggests the opposite – that there is an increased risk of the recurrence of breast cancer in patients taking HRT.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
