Nurses' and Physicians' Rationale Behind Clinical Performance and Interpretation of Routine Prefeed Gastric Aspiration in Preterm Infants: A Cross-sectional Study.

This study aims at understanding the rationale behind performing prefeed gastric aspirations in preterm infants, how nurses and physicians interpret the gastric aspiration and variations between them, and illuminating potential barriers for omitting routine prefeed aspiration. Nurses and physicians from all Danish neonatal intensive care units completed a questionnaire. Of 682 participants, the majority (94%) indicated that they routinely performed prefeed aspiration, primarily to check the feeding tube placement (nurses: 88%, physicians: 46%).

Parasitoids indicate major climate-induced shifts in arctic communities.

Climatic impacts are especially pronounced in the Arctic, which as a region is warming twice as fast as the rest of the globe. Here, we investigate how mean climatic conditions and rates of climatic change impact parasitoid insect communities in 16 localities across the Arctic. We focus on parasitoids in a widespread habitat, Dryas heathlands, and describe parasitoid community composition in terms of larval host use (i.

Onset of main Phanerozoic marine radiation sparked by emerging Mid Ordovician icehouse.

The Great Ordovician Biodiversification Event (GOBE) was the most rapid and sustained increase in marine Phanerozoic biodiversity. What generated this biotic response across Palaeozoic seascapes is a matter of debate; several intrinsic and extrinsic drivers have been suggested. One is Ordovician climate, which in recent years has undergone a paradigm shift from a text-book example of an extended greenhouse to an interval with transient cooling intervals - at least during the Late Ordovician.

Sexuality after total vs. subtotal hysterectomy.

Background: The effect of hysterectomy on sexuality is not fully elucidated and until recently total and subtotal hysterectomies have only been compared in observational studies.

Aims: To compare total abdominal hysterectomy (TAH) to subtotal abdominal hysterectomy (SAH) regarding effects on sexuality.

Methods: In a Danish multicenter trial 319 women were randomized to TAH (n = 158) or SAH (n = 161); 185 women had self-selected TAH (n = 80) or SAH (n = 105) in a simultaneously conducted observational study.
