Size Doesn't Matter: Integrative Taxonomy Shows and Have Overlapping Shell Sizes and Broadly Concordant Distributions.

AbstractThe calyptraeids and , both direct developers, are abundant in the shallow waters of the northeastern Pacific. They have long been considered as two allopatric species that live on different hosts and differ in body size. In this study, we rigorously test this historical hypothesis by assessing molecular taxonomy, museum records, new morphological and host observations, and population genetic structure along the northeast Pacific coast.

Noise-robust breathing-phase estimation on marker-free, ultra low dose X-ray projections for real-time tumor localization via surrogate structures.

Purpose: This paper presents a novel strategy for feature-based breathing-phase estimation on ultra low-dose X-ray projections for tumor motion control in radiation therapy.

Methods: Coarse-scaled Curvelet coefficients are identified as motion sensitive but noise-robust features for this purpose. For feature-based breathing-phase estimation, an ensemble strategy with two classifiers is used.

Stapled intestinal anastomoses are more cost effective than hand-sewn anastomoses in a diagnosis related group system.

Purpose: Creation of an optimal bowel anastomosis with low postoperative leakage rate is an immanent part of colorectal surgery contributing to recovery, length of hospital stay and overall hospital costs. We aimed to investigate costs of small and large bowel resection, length of hospital stay, anastomotic leakage rate and its risk factors depending on the anastomotic technique.

Methods: Retrospective analysis of 198 patients (67 stapled and 131 hand-sewn anastomoses) undergoing elective bowel resection with a single anastomosis without protective ileostomy either stapled or in double-rowed running suture technique between 1st October 2012 and 30th September 2018 at Charité University Hospital Berlin, Campus Benjamin Franklin.

Validation of the German Classification of Diverticular Disease (VADIS)-a prospective bicentric observational study.

Purpose: The German Classification of Diverticular Disease was introduced a few years ago. The aim of this study was to determine whether Classification of Diverticular Disease enables an exact stratification of different types of diverticular disease in terms of course and treatment.

Methods: This was a prospective, bicentric observational trial.

Operative outcome of hernia repair with synthetic mesh in immunocompromised patients.

Background: The safety of synthetic mesh in elective hernia repair in the setting of immunosuppression lacks national and international consensus. The aim of our analysis was to explore the effects of immunosuppression on the rates of wound complications.

Methods: Comparative analysis of immunocompetent and immunocompromised patients with elective mesh repair of inguinal, femoral, primary ventral, incisional or parastomal hernia between January 2001 and December 2013.
