Introduction: Next to existing terminology of the lower urinary tract, due to its increasing complexity, the terminology for pelvic floor dysfunction in women may be better updated by a female-specific approach and clinically based consensus report. Methods: This report combines the input of members of the Standardization and Terminology Committees of two international organizations, the International Urogynecological Association (IUGA), and the International Continence Society (ICS), assisted at intervals by many external referees. Appropriate core clinical categories and a subclassification were developed to give an alphanumeric coding to each definition. An extensive process of 15 rounds of internal and external review was developed to exhaustively examine each definition, with decision-making by collective opinion (consensus). Results: A terminology report for female pelvic floor dysfunction, encompassing over 250 separate definitions, has been developed. It is clinically based with the six most common diagnoses defined. Clarity and user-friendliness have been key aims to make it interpretable by practitioners and trainees in all the different specialty groups involved in female pelvic floor dysfunction. Femalespecific imaging (ultrasound, radiology, and MRI) has been a major addition while appropriate figures have been included to supplement and help clarify the text. Ongoing review is not only anticipated but will be required to keep the document updated and as widely acceptable as possible. Conclusion: A consensus-based terminology report for female pelvic floor dysfunction has been produced aimed at being a significant aid to clinical practice and a stimulus for research. Neurourol.

Histone lysine methylation has been linked to the recruitment of mammalian DNA repair factor 53BP1 and putative fission yeast homolog Crb2 to DNA double-strand breaks (DSBs), but how histone recognition is achieved has not been established. Here we demonstrate that this link occurs through direct binding of 53BP1 and Crb2 to histone H4. Using X-ray crystallography and nuclear magnetic resonance (NMR) spectroscopy, we show that, despite low amino acid sequence conservation, both 53BP1 and Crb2 contain tandem tudor domains that interact with histone H4 specifically dimethylated at Lys20 (H4-K20me2). The structure of 53BP1/H4-K20me2 complex uncovers a unique five-residue 53BP1 binding cage, remarkably conserved in the structure of Crb2, that best accommodates a dimethyllysine but excludes a trimethyllysine, thus explaining the methylation state-specific recognition of H4-K20. This study reveals an evolutionarily conserved molecular mechanism of targeting DNA repair proteins to DSBs by direct recognition of H4-K20me2.

In summary, the results of this study constitute the initial demonstration that TNF receptor proteins are dynamically regulated in patients with advanced congestive heart failure. Moreover, the observation that failing hearts express elevated levels of TNF-alpha suggests that overexpression of this cytokine may be one of several different maladaptive mechanisms responsible for the progressive cardiac decompensation that occurs in advanced heart failure.
