Komplexe proximale Humerusfraktur beim alten Menschen: Winkelstabile Plattenosteosynthese vs. Hemiarthroplastik

Zusammenfassung: Hintergrund: Ziel der vorliegenden Untersuchung ist ein direkter Vergleich der Schulterhemiarthroplastik (SHA) mit der winkelstabilen Plattenosteosynthese (WSPOS) beim alten Patienten mit komplexer proximaler Humerusfraktur. Patienten und Methoden: Zwischen 2003 und 2005 wurden alle Patienten (n=52, Alter ≥70Jahre) mit 3- und 4-Segment-Frakturen des proximalen Humerus, welche mit einer WSPOS (PHILOS®) versorgt wurden, prospektiv erfasst und nach einem Jahr mittels Constant-Score (CS), Oxford Shoulder Score (OSS) und radiologisch nachkontrolliert. Verglichen wurde die WSPOS mit einem historischen Kollektiv mit identischen Einschlusskriterien, welches zwischen 1995 und 1997 an der gleichen Institution mittels SHA versorgt wurde (n=59). Ergebnisse: Beide Patientenkollektive zeigten keine Unterschiede bezüglich Alter, Geschlechterverteilung und Frakturtypen. Der CS war signifikant besser für die WSPOS (median 71 vs. 41). Bezüglich Schmerzen zeigte sich im OSS kein Unterschied zwischen den Gruppen. In der WSPOS-Gruppe mussten signifikant mehr Revisionseingriffe durchgeführt werden (25% vs. 2%). Schlussfolgerung: Die WSPOS liefert beim alten Patienten, bei komplexen proximalen Humerusfrakturen deutlich bessere funktionelle Resultate, ist jedoch mit mehr Rezidiveingriffen behaftet. Die Selbständigkeit der Patienten kann bei beiden Operationsmethoden bei guter Schmerzfreiheit meist erhalten werde

Medication reviews led by community pharmacists in Switzerland: a qualitative survey to evaluate barriers and facilitators.

1) To evaluate the participation rate and identify the practical barriers to implementing a community pharmacist-led medication review service in francophone Switzerland and, 2) To assess the effectiveness of external support. A qualitative survey was undertaken to identify barriers to patient inclusion and medication review delivery in daily practice among all contactable independent pharmacists working in francophone Switzerland (n=78) who were members of a virtual chain (pharmacieplus), regardless of their participation in a simultaneous cross-sectional study. This study analyzed the dissemination of a medication review service including a prescription and drug utilization review with access to clinical data, a patient interview and a pharmaceutical report to the physicians. In addition, we observed an exploratory and external coaching for pharmacists that we launched seven months after the beginning of the cross-sectional study. Poor motivation on the part of pharmacists and difficulties communicating with physicians and patients were the primary obstacles identified. Lack of time and lack of self-confidence in administering the medication review process were the most commonly perceived practical barriers to the implementation of the new service. The main facilitators to overcome these issues may be well-planned workflow organization techniques, strengthened by an adequate remuneration scheme and a comprehensive and practice-based training course that includes skill-building in pharmacotherapy and communication. External support may partially compensate for a weak organizational framework. To facilitate the implementation of a medication review service, a strong local networking with physicians, an effective workflow management and a practice- and communications-focused training for pharmacists and their teams seem key elements required. External support can be useful to help some pharmacists improve their service management skills. Adequate remuneration seems necessary to encourage initial investments to provide such a service. Future research in this area may help improve the process and design of training programs, as well as the monitoring of implementation for each new pharmaceutical service

[Complex fracture of the proximal humerus in the elderly. Locking plate osteosynthesis vs hemiarthroplasty]

The purpose of the present study was a direct comparison of fixed-angle plate fixation (FAPF) and shoulder hemiarthroplasty (SHA) for complex fractures of the proximal humerus in the elderly

Fluorescent dATP for DNA Synthesis In Vivo

Fluorescent nucleoside triphosphates are powerful probes of DNA synthesis, but their potential use in living animals has been previously underexplored. Here, we report the synthesis and characterization of 7-deaza-(1,2,3-triazole)-2'-deoxyadenosine-5'-triphosphate (dATP) derivatives of tetramethyl rhodamine ("TAMRA-dATP"), cyanine ("Cy3-dATP"), and boron-dipyrromethene ("BODIPY-dATP"). Upon microinjection into live zebrafish embryos, all three compounds were incorporated into the DNA of dividing cells; however, their impact on embryonic toxicity was highly variable, depending on the exact structure of the dye. TAMRA-EdATP exhibited superior characteristics in terms of its high brightness, low toxicity, and rapid incorporation and depletion kinetics in both a vertebrate (zebrafish) and a nematode (Caenorhabditis elegans). TAMRA-EdATP allows for unprecedented, real-time visualization of DNA replication and chromosome segregation in vivo
