A retrospective observational study of labour ward work Intensity: The challenge of maternity staffing.

Background: The UK and Ireland are facing significant challenges in the recruitment and retention of midwifery staff. Deficiencies in staffing, training and leadership have been cited as contributory factors to substandard care in both regional and global independent maternity safety reports. Locally, workforce planning is critical to maintaining 'one to one' care for all women in labor and to meet the peaks of daily birthing suite activity.

A redescription of Lithornis vulturinus (Aves, Palaeognathae) from the Early Eocene Fur Formation of Denmark.

The extinct Lithornithidae include several genera and species of flying palaeognathous birds of controversial affinities known from the Early Paleogene of North America and Europe. An almost complete, articulated skeleton from the Early Eocene marine deposits of the Fur Formation (Denmark) was recently assigned to Lithornis vulturinus Owen, 1840. This study provides a detailed redescription and comparison of this three-dimensionally preserved specimen (MGUH 26770), which is one of the best preserved representatives of the Lithornithidae yet known.

[The User Survey on the Revision of the Classification of Therapeutic Procedures].

Introduction: An extensive user survey was conducted in the context of updating the Classification of Therapeutic Procedures (KTL 2015). This paper reflects the results of the user survey and raises critical discussion points.

Methods: The user survey was sent to all rehabilitation centers contracted by the German pension insurance as well as professional associations.

Response to Comment on "Whole-genome analyses resolve early branches in the tree of life of modern birds".

Mitchell et al. argue that divergence-time estimates for our avian phylogeny were too young because of an "inappropriate" maximum age constraint for the most recent common ancestor of modern birds and that, as a result, most modern bird orders diverged before the Cretaceous-Paleogene mass extinction event 66 million years ago instead of after. However, their interpretations of the fossil record and timetrees are incorrect.
