Connected Hearing Devices and Audiologists: The User-Centered Development of Digital Service Innovations.

Today, medical technology manufacturers enter the service market through the development of digital service innovations. In the field of audiology, these developments increasingly shift the service capacities from audiologists to manufacturers and technical systems. However, the technology-driven developments of manufacturers lack acceptance of hearing device users and undermine the important role of audiologists within the service provision.

Effect of metallo-β-lactamase production and multidrug resistance on clinical outcomes in patients with Pseudomonas aeruginosa bloodstream infection: a retrospective cohort study.

Background: Blood stream infections (BSI) with Pseudomonas aeruginosa lead to poor clinical outcomes. The worldwide emergence and spread of metallo-β-lactamase (MBL) producing, often multidrug-resistant organisms may further aggravate this problem. Our study aimed to investigate the effect of MBL-producing P.

Time to positivity as prognostic tool in patients with Pseudomonas aeruginosa bloodstream infection.

Objectives: The time to positivity (TTP), measured as the time span between the start of incubation and the alert signal from the blood culture device, has been described as useful tool of prognosis in patients suffering from blood stream infection with Staphylococcus aureus, Escherichia coli and Klebsiella pneumonia. The present study investigates the relationship between TTP and in-hospital mortality in patients with monomicrobial Pseudomonas aeruginosa blood stream infection (PA-BSI).

Methods: From 2006 until 2012 a retrospective cohort study was undertaken in 3 hospitals in the region surrounding Tübingen, Germany.

Lymphoscintigraphy in patients with primary rectal cancer: the role of total mesorectal excision for primary rectal cancer--a lymphoscintigraphic study.

Background And Aims: Total mesorectal excision based operations is the gold standard of care in patients with middle and lower rectal cancer, but the extent of resection varies widely. In our view, extended lymphadenectomy is unnecessary with precise total mesorectal excision, i.e.

Hydro-Jet assisted laparroscopic cholecystectomy: initial experience in a porcine model.

Background And Objectives: Hydro-Jet technology has long been used for cutting various materials like metal and wood in the industrial field. In the medical field, this technology has been applied successfully for selective cutting of the parenchyma of the liver. However, to our knowledge, no data exist on the use of the Hydro-Jet technique for laparoscopic cholecystectomy.

Vascular closure staples-a new technique for biliary reconstruction: prospective randomized comparison with manual suture in an animal model.

Background: In orthotopic liver transplantation the incidence of biliary complications is up to 49%. In view of the relative frequency of such complications despite seemingly good preconditions, method-related disadvantages of conventional suture must also be considered as a possible cause. These include perforating needle injury of the choledochal wall with at least temporary exposure of suture material in the lumen, suboptimal approximation of the mucosa, and an additional decrease in blood flow in the choledochal stumps as a result of suture-related tissue strangulation.
