Oceans and human health: Sentinel habitats and sentinel species

The health of the oceans and people are inextricably linked. For many years we focused research and policy on anthropogenic impacts to oceans and coasts. Recently we have started to think about how the health of the oceans affects us. In response to the Oceans and Human Health Act of 2004, a NOAA initiative was created to explore the “One Health” of the oceans and coasts. The Center of Excellence in Oceans and Human Health at Hollings Marine Laboratory (HML) is one of three Centers dedicated to understanding the connections and forecasting changes in ocean and coastal health and human health. The Center at HML is developing new tools and approaches, including sentinel habitats and sentinel species, to evaluate linkages between ecological process and human health and wellbeing. The results provide environmental and public health managers, policy-makers and communities forecasts and assessments to improve ecosystem-based management that protects health and mitigates risks for the oceans, coasts and people.(PDF contains 4 pages)

Tem farmacêutico na farmácia: as percepções dos farmacêuticos sobre seu trabalho nas farmácias comunitárias do Estado do Rio de Janeiro

A farmácia comunitária ocupa um importante espaço no cenário da saúde pública brasileira, como local de dispensação de medicamentos e de contínua promoção do consumo de medicamentos para a população. Nesses estabelecimentos, o usuário busca através do consumo de produtos, prescritos ou não, o restabelecimento da sua saúde. O farmacêutico é o profissional de saúde com formação específica sobre medicamentos e que, pelo imperativo da legislação sanitária, é colocado como responsável técnico, nesse lócus. Qual sua motivação para ingressar nessa carreira? Como é a sua práxis e qual a realidade percebida por ele nesse cotidiano? Este trabalho teve como objetivo identificar a concepção que os farmacêuticos responsáveis técnicos, atuantes em farmácias comunitárias do estado do Rio de Janeiro, têm sobre a sua prática profissional e como essa visão pode estar relacionada à implementação de práticas focadas no paciente, tais como a Atenção Farmacêutica. Foram realizadas 15 entrevistas semi-estruturadas com farmacêuticos responsáveis técnicos de farmácias do estado do Rio de Janeiro, representando a seguinte tipologia: farmácias de rede estadual, de rede local e familiar. A categorização do discurso dos farmacêuticos mostrou, pelo menos, quatro convergências: a deficiência no processo de formação acadêmica, a prática farmacêutica migrando para o paciente, as contínuas dificuldades da população quanto ao uso de medicamentos e o conhecimento superficial do conceito de Atenção Farmacêutica. Pensa-se que a realidade encontrada possa não ser muito diferente da de grande número de farmácias comunitárias do próprio estado do Rio de Janeiro, sendo necessário fazer reflexões sobre esse tema, para nos conduzir a um momento de discussão sobre quais elementos poderão vir a garantir, que a práxis farmacêutica se insira com complementaridade nos serviços de saúde.

Prostate biopsy in selecting candidates for hemiablative focal therapy.

Focal therapy (FT) for the management of clinically localized prostate cancer (PCa) is growing from a concept to reality because of increased interest of both patients and physicians. Selection protocols, however, are yet to be established. We discuss the role of prostate biopsy in candidate selection for FT and highlight the different strategies and technical aspects of the use of prostate biopsy in this setting. In our opinion, prostate biopsy plays a major role in the selection process and tailoring appropriate treatment strategy to the patient. FT necessitates dedicated biopsy schemes that would reliably predict the extent, nature, and location of PCa in selected patients. Currently, there is insufficient scientific evidence to propose a specific biopsy scheme that could fit every candidate, providing accurate characterization of the disease in the individual patient. Further research is necessary to establish solid selection protocols that would reliably identify appropriate candidates for FT of PCa.

When the library is located in prime real estate: a case study on the loss of space from the Duke University Medical Center Library and Archives.

The Duke University Medical Center Library and Archives is located in the heart of the Duke Medicine campus, surrounded by Duke Hospital, ambulatory clinics, and numerous research facilities. Its location is considered prime real estate, given its adjacency to patient care, research, and educational activities. In 2005, the Duke University Library Space Planning Committee had recommended creating a learning center in the library that would support a variety of educational activities. However, the health system needed to convert the library's top floor into office space to make way for expansion of the hospital and cancer center. The library had only five months to plan the storage and consolidation of its journal and book collections, while working with the facilities design office and architect on the replacement of key user spaces on the top floor. Library staff worked together to develop plans for storing, weeding, and consolidating the collections and provided input into renovation plans for users spaces on its mezzanine level. The library lost 15,238 square feet (29%) of its net assignable square footage and a total of 16,897 (30%) gross square feet. This included 50% of the total space allotted to collections and over 15% of user spaces. The top-floor space now houses offices for Duke Medicine oncology faculty and staff. By storing a large portion of its collection off-site, the library was able to remove more stacks on the remaining stack level and convert them to user spaces, a long-term goal for the library. Additional space on the mezzanine level had to be converted to replace lost study and conference room spaces. While this project did not match the recommended space plans for the library, it underscored the need for the library to think creatively about the future of its facility and to work toward a more cohesive master plan.

Hanging Flower Baskets, Blowing in the Wind? Third Sector Groups, Cross-Border Partnerships and the EU Peace Programmes in Ireland

The EU’s Peace programmes in Ireland have promoted the cross-border activity of Third sector groups. Potentially, such activity gives substantive meaning to regional cross-border governance and helps to ameliorate ethno-national conflict by providing positive sum outcomes for ‘post-conflict’ communities. The paper mobilizes focused research conducted by the authors to explore this potential. It finds that while regional cross-border governance has indeed developed under the Peace programmes, the sustainability of the social partnerships underpinning this governance is uncertain and its significance for conflict resolution is qualified by difficulties in forming a stable power-sharing arrangement at the political elite level.

Respecting autonomy without disclosing information

There is widespread agreement that it would be both morally and legally wrong to treat a competent patient, or to carry out research with a competent participant, without the voluntary consent of that patient or research participant. Furthermore, in medical ethics it is generally taken that that consent must be informed. The most widely given reason for this has been that informed consent is needed to respect the patient’s or research participant’s autonomy. In this article I set out to challenge this claim by considering in detail each of the three most prominent ways in which ‘autonomy’ has been conceptualized in the medical ethics literature. I will argue that whilst these accounts support the claim that consent is needed if the treatment of competent patients, or research on competent individuals, is to respect their autonomy, they do not support the claim that informed consent is needed for this purpose.

Evidence-based practice: the relevance of systematic reviews.

Aim:
To demonstrate how systematic reviews provide robust evidence to inform clinical decision making in practice.

Background
Systematic reviews collate findings from a number of research studies in order to provide a comprehensive and reliable summary of the best available evidence. The use of systematic reviews to inform practice based decisions has increased as a result of the overwhelming amount of research literature available, poor quality of research evidence and the need to ensure practice is based upon the best available evidence. Systematic reviews are an efficient way of coping with large volumes of data to answer focused research questions. They differ from traditional literature reviews as they adhere to an explicit scientific process. The use of explicit and rigorous methods to identify, appraise and synthesise relevant studies minimises bias and provides a reliable basis for decision making. As a result systematic reviews provide clear evidence on the effectiveness of a healthcare intervention to inform policy and decision making across healthcare systems. An example of how the findings from systematic reviews can provide reliable evidence to inform healthcare decisions will be provided in this presentation1. This will demonstrate how focused clinical questions can be answered by systematic reviews and translated into practice.

Factors affecting treatment decision making for women with breast cancer

This study examined the factors affecting treatment decision making for young women with early stage breast cancer. Thirty women, aged 35 to 52 years, were presented information about two equally effective chemotherapy treatments following surgery for breast cancer using an educational instrument called a "decision board." Although equally effective, the treatments differ with regards to side effects and treatment schedule. The purpose of this research was to investigate what factors affect the decision-making process. Following administration of the decision board, women were given a take-home version to review and asked to return one to two weeks later with a decision, at which time they completed a questionnaire. theoretical framework for this study was constructed from the literature on self-directed learning and critical thinking. The Overall, the factors rated most important to the treatment decision were related to quality of life, side effects, and length of treatment. Five factors were found to be rated significantly different by the women who chose one treatment versus the other in terms of importance to their decision. These were side effects in general, vomiting, hair loss, family role, and the number of trips to the cancer centre required for treatment.Implications and recommendations for patient education, research, and practice evolved from the findings of this study.

Modeling of Suspended Sediment Dynamics in Tropical River Basins

It is proposed to study the suspended sediment transport characteristics of river basins of Kerala and to model suspended sediment discharge mechanism for typical micro-watersheds. The Pamba river basin is selected as a representative hydrologic regime for detailed studies of suspended sediment characteristics and its seasonal variation. The applicability of various erosion models would be tested by comparing with the observed event data (by continuous monitoring of rainfall, discharge, and suspended sediment concentration for lower order streams). Empirical, conceptual and physically distributed models were used for making the comparison of performance of the models. Large variations in the discharge and sediment quantities were noticed during a particular year between the river basins investigated and for an individual river basin during the years for which the data was available. In general, the sediment yield pattern follows the seasonal distribution of rainfall, discharge and physiography of the land. This confirms with similar studies made for other Indian rivers. It was observed from this study, that the quantity of sediment transported downstream shows a decreasing trend over the years corresponding to increase in discharge. For sound and sustainable management of coastal zones, it is important to understand the balance between erosion and retention and to quantify the exact amount of the sediments reaching this eco-system. This, of course, necessitates a good length of time series data and more focused research on the behaviour of each river system, both present and past. In this realm of river inputs to ocean system, each of the 41 rivers of Kerala may have dominant yet diversified roles to influence the coastal ecosystem as reflected from this study on the major fraction of transport, namely the suspended sediments

Incident-Reporting-Systeme als Möglichkeit zum organisationalem Lernen (nicht nur) aus Fehlern und kritischen Ereignissen

Die vorliegende Dissertation betrachtet institutionsinterne lokale (Critical-)Incident-Reporting-Systeme ((C)IRS) als eine Möglichkeit zum Lernen aus Fehlern und unerwünschten kritischen Ereignissen (sogenannte Incidents) im Krankenhaus. Die Notwendigkeit aus Incidents zu lernen, wird im Gesundheitswesen bereits seit den 1990er Jahren verstärkt diskutiert. Insbesondere risikoreichen Organisationen, in denen Incidents fatale Konsequenzen haben können, sollten umfassende Strategien erarbeiten, die sie vor Fehlern und unerwünschten Ereignissen schützen und diese als Lernpotenzial nutzen können. Dabei können lokale IRS als ein zentraler Bestandteil des Risikomanagements und freiwillige Dokumentationssysteme im Krankenhaus ein Teil dieser Strategie sein. Sie können eine Ausgangslage für die systematische Erfassung und Auswertung von individuellen Lerngelegenheiten und den Transfer zurück in die Organisation schaffen. Hierfür sind eine lernförderliche Gestaltung, Implementierung und Einbettung lokaler IRS eine wichtige Voraussetzung. Untersuchungen über geeignete lerntheoretisch fundierte und wirkungsvolle IRS-Modelle und empirische Daten fehlen bisher im deutschsprachigen Raum. Einen entsprechenden Beitrag leistet die vorliegende Fallstudie in einem Schweizer Universitätsspital (800 Betten, 6.100 Mitarbeitende). Zu diesem Zweck wurde zuerst ein Anforderungsprofil an lernförderliche IRS aus der Literatur abgeleitet. Dieses berücksichtigt zum einen literaturbasierte Kriterien für die Gestaltung und Nutzung aus der IRS-Literatur, zum anderen die aus der Erziehungswissenschaft und Arbeitspsychologie entlehnten Gestaltungsbedingungen und Erfolgskriterien an organisationales Lernen. Das Anforderungsprofil wurde in drei empirischen Teilstudien validiert und entsprechend adaptiert. In der ersten empirischen Teilstudie erfolgte eine Standortbestimmung der lokalen IRS. Die Erhebung erfolgte in vier Kliniken mittels Dokumentenanalyse, leitfadengestützter Interviews (N=18), sieben strukturierter Gruppendiskussionen und teilnehmender Beobachtungen über einen Zeitraum von 22 Monaten. Erfolgskritische IRS-Merkmale wurden identifiziert mit dem Ziel einer praxisgerechten lernförderlichen Systemgestaltung und Umsetzung von Incident Reporting unter Betrachtung von organisationalen Rahmenbedingungen, Lernpotenzialen und Barrieren. Die zweite Teilstudie untersuchte zwei Fallbeispiele organisationalen Lernens mittels Prozessbegleitung, welche zu einem verwechslungssicheren Design bei einem Medizinalprodukt und einer verbesserten Patientenidentifikation in Zusammenhang mit Blutentnahmen führten. Für das organisationale Lernen im Spital wurden dabei Chancen, Barrieren und Gestaltungsansätze abgeleitet, wie erwünschte Veränderungen und Lernen unter Nutzung von IRS initiiert werden können und dabei ein besseres Gesundheitsresultat erreicht werden kann. Die dritte Teilstudie überprüfte, inwiefern die Nutzung und Implementierung lokaler IRS mittels einer Mitarbeitervollbefragung zur Sicherheitskultur gefördert werden kann. Hierfür wurde eine positive Interaktion, zwischen einer starken Sicherheitskultur und der Bereitschaft ein IRS zu implementieren und Incidents zu berichten, angenommen. Zum Einsatz kam eine deutschsprachige Version des Hospital Survey on Patient Safety Culture (Patientensicherheitsklimainventar) mit einem Rücklauf von 46.8% (2.897 gültige Fragebogen). In 23 von 37 Kliniken führte laut einer Nachbefragung die Sicherheitskulturbefragung zum Implementierungsentscheid. Dies konnte durch Monitoring der IRS-Nutzung bestätigt werden. Erstmals liegen mit diesen Studien empirische Daten für eine wirkungsvolle und lernförderliche Gestaltung und Umsetzung von lokalen IRS am Beispiel einer Schweizer Gesundheitsorganisation vor. Die Ergebnisse der Arbeit zeigen Chancen und Barrieren für IRS als Berichts- und Lernsysteme im Krankenhaus auf. Als Resultat unsachgemäss gestalteter und implementierter IRS konnte dabei vor allem Lernverhinderung infolge IRS aufgezeigt werden. Blinder Aktionismus und eine fehlende Priorisierung von Patientensicherheit, unzureichende Kompetenzen, Qualifikationen und Ressourcen führten dabei zur Schaffung neuer Fehlerquellen mit einer Verstärkung des Lernens erster Ordnung. Eine lernförderliche Gestaltung und Unterhaltung der lokalen IRS, eingebettet in eine klinikumsweite Qualitäts- und Patientensicherheitsstrategie, erwiesen sich hingegen als wirkungsvoll im Sinne eines organisationalen Lernens und eines kontinuierlichen Verbesserungsprozesses. Patientensicherheitskulturbefragungen erwiesen sich zudem bei entsprechender Einbettung als effektives Instrument, um die Implementierung von IRS zu fördern. Zwölf Thesen zeigen in verdichteter Form auf, welche Gestaltungsprinzipien für IRS als Instrument des organisationalen Lernens im Rahmen des klinischen Risikomanagements und zur Förderung einer starken Patientensicherheitskultur zu berücksichtigen sind. Die Erkenntnisse aus den empirischen Studien münden in ein dialogorientiertes Rahmenmodell organisationalen Lernens unter Nutzung lokaler IRS. Die Arbeit zeigt damit zum einen Möglichkeiten für ein Lernen auf den verschiedenen Ebenen der Organisation auf und weist auf die Notwendigkeit einer (Re-)Strukturierung der aktuellen IRS-Diskussion hin.

Eficacia de las intervenciones psicoeducativas en pacientes con esquizofrenia: una revisión sistemática

Introducción: La esquizofrenia es una enfermedad crónica que genera deterioro cognitivo y diversos grados de discapacidad. Dentro del tratamiento no solo debe considerarse el abordaje farmacológico sino también un enfoque psicoterapéutico. La psicoeducación es una intervención terapéutica con alto potencial en el manejo de pacientes con esquizofrenia, tiene importantes resultados especialmente en el área cognitiva. Métodos: Revisión sistemática de la literatura de artículos de bases de datos y búsqueda manual de revistas relacionadas que aportaran la mejor evidencia. Se evaluó calidad metodológica de los estudios y estos se organizaron en tablas de evidencia. Resultados: De 34 artículos potenciales, se seleccionaron finalmente dos para ser incluidos en la revisión. Se clasificaron como nivel de evidencia I. A pesar de la ambigüedad de las comparaciones, en general, las intervenciones psicoeducativas aportan beneficios con disminución de recaídas y reingresos hospitalarios. Discusión: La amplia gama de comparaciones aportó complejidad en el momento de incluir estudios para la presente revisión, la falta de detalle sobre aspectos propios de la intervención utilizada en cada estudio, generó limitaciones al momento de realizar comparaciones. La psicoeducación aporta beneficios, sin embargo debe tenerse en cuenta el compromiso cognitivo propio de la enfermedad, al momento de evaluar los desenlaces de este tipo de intervenciones. Conclusión: Las intervenciones psicoeducativas juegan un importante papel en el tratamiento de los pacientes con esquizofrenia. Es necesaria la realización de más estudios que consoliden con mayor firmeza la evidencia científica en éste área en particular.
