Changes in bone mineral density over 18 months following kidney transplantation: the respective roles of prednisone and parathyroid hormone

Prednisone is a major factor of bone loss after kidney transplantation. The role of hyperparathyroidism and immunosuppressors is less clear.

Graft remodeling during growth following anterior cruciate ligament reconstruction in skeletally immature sheep

INTRODUCTION: Ruptures of the anterior cruciate ligament are being diagnosed with increasing frequency in skeletally immature individuals. It was our aim to investigate the graft remodelling process following an autologous, transphyseal reconstruction of the anterior cruciate ligament (ACL) in skeletally immature sheep. We hypothesized that the ligamentisation process in immature sheep is quicker and more complete when compared to adult sheep. MATERIALS AND METHODS: Skeletally immature sheep with an age of 4 months underwent a fully transphyseal ACL reconstruction using an autologous tendon. The animals were subsequently sacrificed at 3, 6, 12 and 24 weeks following surgery. Each group was characterised histomorphometrically, by immunostaining (VEGF, SMA), by transmission electron microscopy (TEM) and biomechanically (UFS Roboter). RESULTS: The histomorphometric analysis and presence of VEGF and SMA positive cells demonstrated a rapid return to a ligament like structure. The biomechanical analysis revealed an anteroposterior translation that was still increased even 6 months following surgery. CONCLUSION: As in adult sheep models, the remodeling of a soft tissue graft used for ACL reconstruction results in a biomechanically inferior substitute. However, the immature tissue seems to remodel faster and more complete when compared to adults.

Eine neue Schrift für die Wolof-Sprache

Ich möchte mich zuerst bei allen bedanken, die Interesse an Schriften in Afrika entwickelt haben. Aufrichtiger Dank richtet sich daher an Helma Pasch und Anja Kootz für ihre bemerkenswerten Bemühungen. Vielen Dank auch an alle, die zur Verwirklichung der Tagung „5000 Jahre Schrift in Afrika“ beigetragen haben. Insofern geht ein besonderer Dank an die Fritz-Thyssen-Stiftung, den Förderer der Tagung.

Public Governance – Entwicklungen und Herausforderungen

Die aktuellen Entwicklungen der öffentlichen Aufgabenerfüllung und deren Finanzierung in zahlreichen Ländern werfen die Frage nach einer nachhalti-gen Staats- und Verwaltungsführung auf. Welche Aufgaben soll der Staat selbst erfüllen – und welche im staatlichen Verbund oder partnerschaftlich zusammen mit Privaten? Wie ist die Finanzierung unter Wahrung des Haus-haltgleichgewichts sicherzustellen? Nach welchen Modellen organisiert und führt der Staat seine Verwaltung? Und wie wird die Wirksamkeit und Effizi-enz der Aufgabenerfüllung im demokratischen Rechtsstaat überprüft? Die vorliegende Jubiläumsschrift zum 10-jährigen Bestehen des Kompetenz-zentrums für Public Management der Universität Bern vermittelt eine Über-sicht über das Schaffen des KPM, über dessen Umfeld sowie über aktuelle Forschungsprojekte und neue Forschungsfelder. Die Jubiläumsschrift ver-bindet Wissenschaft und Praxis der Public Governance aus einer nationalen und internationalen Perspektive. Und sie thematisiert den Mehrwert der verwaltungswissenschaftlichen Aus- und Weiterbildung bei der Bewältigung der Herausforderungen der Public Governance im Berufsalltag.

A survey of paediatric HIV programmatic and clinical management practices in Asia and sub-Saharan Africa--the International epidemiologic Databases to Evaluate AIDS (IeDEA)

INTRODUCTION There are limited data on paediatric HIV care and treatment programmes in low-resource settings. METHODS A standardized survey was completed by International epidemiologic Databases to Evaluate AIDS paediatric cohort sites in the regions of Asia-Pacific (AP), Central Africa (CA), East Africa (EA), Southern Africa (SA) and West Africa (WA) to understand operational resource availability and paediatric management practices. Data were collected through January 2010 using a secure, web-based software program (REDCap). RESULTS A total of 64,552 children were under care at 63 clinics (AP, N=10; CA, N=4; EA, N=29; SA, N=10; WA, N=10). Most were in urban settings (N=41, 65%) and received funding from governments (N=51, 81%), PEPFAR (N=34, 54%), and/or the Global Fund (N=15, 24%). The majority were combined adult-paediatric clinics (N=36, 57%). Prevention of mother-to-child transmission was integrated at 35 (56%) sites; 89% (N=56) had access to DNA PCR for infant diagnosis. African (N=40/53) but not Asian sites recommended exclusive breastfeeding up until 4-6 months. Regular laboratory monitoring included CD4 (N=60, 95%), and viral load (N=24, 38%). Although 42 (67%) sites had the ability to conduct acid-fast bacilli (AFB) smears, 23 (37%) sites could conduct AFB cultures and 18 (29%) sites could conduct tuberculosis drug susceptibility testing. Loss to follow-up was defined as >3 months of lost contact for 25 (40%) sites, >6 months for 27 sites (43%) and >12 months for 6 sites (10%). Telephone calls (N=52, 83%) and outreach worker home visits to trace children lost to follow-up (N=45, 71%) were common. CONCLUSIONS In general, there was a high level of patient and laboratory monitoring within this multiregional paediatric cohort consortium that will facilitate detailed observational research studies. Practices will continue to be monitored as the WHO/UNAIDS Treatment 2.0 framework is implemented.

Street-level bureaucrats and new modes of governance - How conflicting roles affect the implementation of the Swiss Ordinance on Verterinary Drugs

Lipsky’s seminal concept of street-level bureaucrats (SLBs) focuses on their role as public servants. However, in the course of new modes of governance, private actors have gained an additional role as implementation agents. We explore the logic of private SLBs during the implementation of the Swiss Ordinance on Veterinary Medicinal Products (OVMP) where veterinarians are simultaneously implementing agents, policy addressees, and professionals with economic interests. We argue that, because of contradictory reference systems, it is problematic for the output performance if an actor is simultaneously the target group of a policy and its implementing agent.

Im Herzen der Macht? Hauptstädte und ihre Funktion

Hauptstädte (Capital Cities) spielen eine wichtige Rolle für die kulturelle, soziale und politische Identität eines Landes. Sie gelten als Schaltzentralen und ihre Macht drückt sich nicht nur in ihrem repräsentativen Stadtbild aus, sondern auch in der Art und Weise, wie sich diese Städte in nationalen und internationalen Netzwerken positionieren.
