Das vorliegende Papier stellt den Endbericht des Projektes „regio pro – Flächendeckende Einführung des Frühinformationssystems zur Qualifikations- und Beschäftigungsentwicklung in Hessen“ dar. Erstellt wurde der vorliegende Bericht im Dezember 2014. Der gesamte Projektzeitraum erstreckte sich vom 01.06.2011 bis zum 31.12.2014. Gefördert wird das Projekt vom Hessischen Ministerium für Wirtschaft, Energie, Verkehr und Landesentwicklung aus dem Europäischen Sozialfonds und Landesmitteln.
Objectives: It is known that transition, as a shift of care, marks a vulnerable phase in the adolescents’ lives with an increased risk for non-adherence and allograft failure. Still, the transition process of adolescents and young adults living with a kidney transplant in Germany is not well defined. The present research aims to assess transition-relevant structures for this group of young people. Special attention is paid to the timing of the process.
Setting: In an observational study, we visited 21 departments of paediatric nephrology in Germany. Participants were doctors (n=19), nurses (n=14) and psychosocial staff (n=16) who were responsible for transition in the relevant centres. Structural elements were surveyed using a short questionnaire. The experiential viewpoint was collected by interviews which were transcribedverbatim before thematic analysis was performed.
Results: This study highlights that professionals working within paediatric nephrology in Germany are well aware of the importance of successful transition. Key elements of transitional care are well understood and mutually agreed on. Nonetheless, implementation within daily routine seems challenging, and the absence of written, structured procedures may hamper successful transition.
Conclusions: While professionals aim for an individual timing of transfer based on medical, social, emotional and structural aspects, rigid regulations on transfer age as given by the relevant health authorities add on to the challenge.

Background: Incisional heia is a frequent complication of midline laparotomy. The use of mesh in hernia repair has been reported to lead to fewer recurrences compared to primary repair. However, in Ventral Hernia Working Group (VHWG) Grade 3 hernia patients, whose hernia is potentially contaminated, synthetic mesh is prone to infection. There is a strong preference for resorbable biological mesh in contaminated fields, since it is more able to resist infection, and because it is fully resorbed, the chance of a foreign body reaction is reduced. However, when not crosslinked, biological resorbable mesh products tend to degrade too quickly to facilitate native cellular ingrowth. Phasix™ Mesh is a biosynthetic mesh with both the biocompatibility and resorbability of a biological mesh and the mechanical strength of a synthetic mesh. This multi-center single-arm study aims to collect data on safety and performance of Phasix™ Mesh in Grade 3 hernia patients.
Methods: A total of 85 VHWG Grade 3 hernia patients will be treated with Phasix™ Mesh in 15 sites across Europe. The primary outcome is Surgical Site Occurrence (SSO) including hematoma, seroma, infection, dehiscence and fistula formation (requiring intervention) through 3 months. Secondary outcomes include recurrence, infection and quality of life related outcomes after 24 months. Follow-up visits will be at drain removal (if drains were not placed, then on discharge or staple removal instead) and in the 1st, 3rd, 6th, 12th, 18th and 24th month after surgery.
Conclusion: Based on evidence from this clinical study Depending on the results this clinical study will yield, Phasix™ Mesh may become a preferred treatment option in VHWG Grade 3 patients.
Trial registration: The trial was registered on March 25, 2016 on clinicaltrials.gov: NCT02720042.
Introduction: Information on the long-term performance of biosynthetic meshes is scarce. This study analyses the performance of biosynthetic mesh (Phasix™) over 24 months.
Methods: A prospective, international European multi-center trial is described. Adult patients with a Ventral Hernia Working Group (VHWG) grade 3 incisional hernia larger than 10 cm2, scheduled for elective repair, were included. Biosynthetic mesh was placed in sublay position. Short-term outcomes included 3-month surgical site occurrences (SSO), and long-term outcomes comprised hernia recurrence, reoperation, and quality of life assessments until 24 months.
Results: Eighty-four patients were treated with biosynthetic mesh. Twenty-two patients (26.2%) developed 34 SSOs, of which 32 occurred within 3 months (primary endpoint). Eight patients (11.0%) developed a hernia recurrence. In 13 patients (15.5%), 14 reoperations took place, of which 6 were performed for hernia recurrence (42.9%), 3 for mesh infection (21.4%), and in 7 of which the mesh was explanted (50%). Compared to baseline, quality of life outcomes showed no significant difference after 24 months. Despite theoretical resorption, 10.7% of patients reported presence of mesh sensation in daily life 24 months after surgery.
Conclusion: After 2 years of follow-up, hernia repair with biosynthetic mesh shows manageable SSO rates and favorable recurrence rates in VHWG grade 3 patients. No statistically significant improvement in quality of life or reduction of pain was observed. Few patients report lasting presence of mesh sensation. Results of biosynthetic mesh after longer periods of follow-up on recurrences and remodeling will provide further valuable information to make clear recommendations.

White paper peanut allergy
(2022)
The current management of a primary IgE-mediated peanut allergy consists of the two basic pillars “exposure prophylaxis” with avoidance of the allergen and “emergency therapy” with short-term treatment of an acute allergic reaction after accidental ingestion. Accidental reactions are common despite attempted avoidance. The severity of an allergic or even anaphylactic reaction after accidental ingestion is difficult to assess prior to reaction. In addition, reaction thresholds may vary depending on the accompanying augmentation factor. Therefore, every peanut allergic patient should receive individual dietary counseling as well as instructions for the use of the emergency kit and a structured patient education program (anaphylaxis group training), if necessary. For the first time, since fall 2021 a causal treatment option with a drug for oral immunotherapy will now be available for 4‑ to 17-year-old peanut-allergic children and adolescents. The oral immunotherapy with peanut protein as defatted powder of Arachis hypogaea L., semen (peanuts) leads to desensitization with a good efficacy record and an acceptable safety profile. Other treatment options with different therapeutic approaches are also under development and will probably expand the range for treatment in the coming years.

Background: Peanuts are a member of the legume family (botanical family Leguminosae) and peanut allergies are the most common cause of food anaphylaxis in many countries. The prevalence of peanut allergy is increasing.
Methods: Experts from Germany and Austria performed a standardized literature search and published their consensus recommendations in a White Paper on Peanut Allergy, which this care pathway is based upon, thus, providing a comprehensive diagnosis and treatment algorithm.
Results: The most important diagnostic key elements include a detailed clinical medical history, evidence of peanut-specific sensitization by means of skin prick testing and/or in vitro determination of the peanut (extract)-specific IgE and/or the molecular component diagnostics (most important Ara h 2-specific IgE, sometimes also Ara h1-, 3-, 6-, 8- and 9-specific IgE) as well as the gold standard, the double-blind, placebo-controlled food challenge. The diagnostic algorithms were created for the following constellations: Suspected primary peanut allergy with a clear history of systemic immediate-type reaction, suspected primary peanut allergy with questionable symptoms, suspected secondary (possibly pollen-associated) peanut allergy with a history of solely oropharyngeal symptoms and incidental finding of sensitization and no peanut ingestion so far.
Conclusions: After established diagnosis the standard of care is counseling to avoid peanut contact and prescription of emergency medications (oral antihistamines, oral steroids, inhaled β2-agonists, injectable intramuscular epinephrine) as needed. Instruction on the use of these emergency medications should be provided. A preparation for oral immunotherapy (OIT) for 4 to 17 years old peanut allergic children/ adolescents has been recently approved by the regulatory authorities. OIT for peanut allergy shows high efficacy and an acceptable safety profile, improves quality of life, and health economic aspects. Thus it offers a therapeutic option for peanut allergic children and adolescents.
