The present study analyzes the influence of the addition of monocytes to a biphasic bone substitute with two granule sizes (400-700 μm and 500-1000 μm). The majority of the added monocytes was detectable as mononuclear cells, while also low amounts of (chimeric) multinucleated giant cells (MNGCs) were found. No increase in the total number of MNGCs was established, but a significantly increased percent vascularization. Altogether, the results show that the added monocytes become involved in the tissue response to a biomaterial without marked changes in the overall reaction. Monocyte addition enables an increased implant bed vascularization especially via induction of vessel maturation and, thus intervenes positively in the healing reaction to a biomaterial. © 2016 Wiley Periodicals, Inc.

Hematology patients require central venous catheters for cancer treatment and nutrition, which increases their risk of intravascular device-associated bacteremia. In the absence of recent data, we investigated intravascular device-associated bacteremia in this specific context. A three-month surveillance was conducted annually in 27 hematology wards, using a protocol derived from the HAI-Net ICU ECDC protocol (2020-2024).

Treatment of patients with severe hearing loss or deafness using cochlear implants (CI) is nowadays clinical routine. In the Hannover Medical School alone, more than 500 patients are treated with CI annually, meaning that the pool of patients with CI increases significantly each year. Worldwide, there are over 1 million patients with a CI system; in Germany the figure is estimated at over 60,000.

Car accidents, infections caused by bacteria or viruses, metastatic lesions, tumors, and malignancies are the most frequent causes of chest wall damage, leading to the removal of the affected area. After excision, artificial bone or synthetic materials are used in chest wall reconstruction to restore the skeletal structure of the chest. Chest implants have traditionally been made from metallic materials like titanium alloys due to their biocompatibility and durability.

Background: Sudden cardiac arrest (SCA) risk stratification in patients with mitral valve prolapse (MVP) may be complicated by other potential causes of arrhythmia.
Objectives: We aimed to characterize SCA survivors with isolated (iMVP) and non-isolated MVP (non-iMVP) and to assess their long-term follow-up.
Methods: This ambispective study included 75 patients with MVP who experienced SCA and were treated in our center between 2009-2024.
