Worlds of scientific cooperation. Choosing appropriate data for specific networks.

This paper discusses data commonly used to study scientific cooperation, especially over the last three decades. Among the extensive bibliography using these data, our selection of articles highlights geographical levels most used to study "Worlds" of Scientific Cooperation in order to outline the advantages and limits of such a choice. Generally, the articles examined here do not take into account changes undergone by spatial units over time, such as modifications in weight and in the centrality index. These articles also tend to focus on key scientific fields such as nanotechnology. Very few studies examine small scientific communities such as the "DNA Transcription and Repair Group", even from a sociological viewpoint. After focusing on the publishing locations of the Group's first papers, we will define the field's trajectories over time by trying to answer questions such as "How does this small community's network evolve?" "Are the original locations still central to the evolving network?" This case study of the "Worlds" of Scientific Cooperation leads to questions such as "Are scientific activities substantially different from economic activities, such as the flow of finance or goods?" "What can a multi-level approach to Scientific Cooperation offer?

Zur Rolle des CD30 Liganden bei der Induktion einer spezifischen Immunantwort gegen Melanomzellen

Das maligne Melanom ist einer der am stärksten immunogenen, soliden Tumoren weswegen Immuntherapien zu einem Standardtherapiekonzept geworden sind. Die Mitglieder der TNFR Familie können zusätzliche Aktivierungssignale zur Aktivierung von T-Zellen liefern. CD30L wurde im Vergleich zu B7-1 als kostimulatorisches Molekül evaluiert. CD30L und B7-1 konnten auf Melanomzellen stabil zur Expression gebracht werden. Diese Melanomzellen wurden mit T-Zellen inkubiert und die induzierte Expression von Aktivierungsmarkern sowie die Proliferationsraten gemessen. CD30L besitzt nur geringe primäre Stimulationsfähigkeit für T-Zellen. Seine Rolle bei der sekundären Aktivierung konnte noch nicht eindeutig geklärt werden, da der erzielte Effekt abhängig ist vom Aktivierungszustand der eingesetzten T-Zellen und von den gewählten experimentellen Bedingungen. Die genauen Umstände unter welchen CD30L aktivierend oder Apoptose induzierend wirkt müssen noch näher definiert werde

A scoping review of nurse-led randomised controlled trials

Background: Nurses comprise the largest portion of the healthcare workforce worldwide. However, nurse representation in the leadership of clinical research and research funding is largely unknown. The Australasian Nursing and Midwifery Clinical Trials Network was established to provide a coordinated network, focussed on building research capacity in nursing and midwifery. To support this work, this scoping review of nurse-led randomised controlled trials was conducted to summarise research activity, as well as highlight future research directions, gaps and resources. Midwife-led trials will be reported elsewhere. Aim: To quantify number, type and quality of nurse-led randomised controlled trials registered between 2000–2021. Design: A scoping review of RCTs. Data Sources: Medline, Emcare and Scopus were searched from 2000 to August 2021. ANZCTR, NHMRC, MRFF and HRC (NZ) registries were searched from inception to July 2021. Review Methods: This review was informed by the JBI scoping review framework using the PRISMA-ScR. Results: Our search yielded 186 nurse-led publications and 279 registered randomised controlled trials. Multiple trials had the same nurse leaders. There were more registrations than publications. Publications were predominantly of high methodological quality; however, there was a reliance on active controls and blinding low. Trial registrations indicate that universities and hospital/healthcare organisations were the major sources of funding, while publications indicate that Governments and the National Health and Medical Research Council were the main funding bodies. Conclusion: A small number of high-quality, large-scale, nationally funded randomised controlled trials were identified, with a larger number of locally funded small trials. There was a disparity between the number of registered trials and those published. Additional infrastructure, funding and career frameworks are needed to enable nurses to design, conduct and publish clinical trials that inform the health system and improve health outcomes. Relevance to Clinical Practice: Research initiated and led by nurses has the potential to improve the health and well-being of individuals and communities, and current nurse-led research is of high methodological quality; however, there were very few nurse-led RCTs, conducted by a small pool of nurse researchers. This gap highlights the need for support in the design, conduct and publishing of nurse-led RCTs. Patient or Public Contribution: This is a scoping review; therefore, patient or public contribution is not applicable

Midwife led randomised controlled trials in Australia and New Zealand: A scoping review

Background: Midwives are the largest workforce involved in caring for pregnant women and their babies, and are well placed to translate research into practice and ensure midwifery priorities are appropriately targeted in researched. Currently, the number and focus of randomised controlled trials led by midwives in Australia and New Zealand is unknown. The Australasian Nursing and Midwifery Clinical Trials Network was established in 2020 to build nursing and midwifery research capacity. To aid this, scoping reviews of the quality and quantity of nurse and midwife led trials were undertaken. Aim: To identify midwife led trials conducted between 2000 and 2021 in Australia and New Zealand. Methods: This review was informed by the JBI scoping review framework. Medline, Emcare, and Scopus were searched from 2000-August 2021. ANZCTR, NHMRC, MRFF, and HRC (NZ) registries were searched from inception to July 2021. Findings: Of 26,467 randomised controlled trials registered on the Australian and New Zealand Clinical Trials Registry, 50 midwife led trials, and 35 peer-reviewed publications were identified. Publications were of moderate to high quality with scores limited due to an inability to blind participants or clinicians. Blinding of assessors was included in 19 published trials. Discussion: Additional support for midwives to design and conduct trials and publish findings is required. Further support is needed to translate registration of trial protocols into peer reviewed publications. Conclusion: These findings will inform the Australasian Nursing and Midwifery Clinical Trials Network plans to promote quality midwife led trials

Harnessing the nursing and midwifery workforce to boost Australia\u27s clinical research impact

For the Medical Research Future Fund (MRFF) to achieve its full impact, it is necessary for health practitioners to be trained and reliably funded to deliver research and translation alongside their clinical work. We offer insight into current systems, concerns and suggestions as this applies to clinical research in nursing and midwifery. Nurses and midwives globally have a long record of delivering high quality clinical research that improves care and outcomes. An analysis of four landmark nursing-led studies in the United States illustrates the value-adding potential of such research: for every grant dollar, the return on investment ranged from $202 to$1206. In Australia, investment in nursing- and midwifery-led research also pays dividends for health care costs and population and health system outcomes, as evidenced from the many research contributions of Australian nurses and midwives over the past decade (Box)

Professional care workforce: a rapid review of evidence supporting methods of recruitment, retention, safety, and education

Background: Across the care economy there are major shortages in the health and care workforce, as well as high rates of attrition and ill-defined career pathways. The aim of this study was to evaluate current evidence regarding methods to improve care worker recruitment, retention, safety, and education, for the professional care workforce. Methods: A rapid review of comparative interventions designed to recruit, retain, educate and care for the professional workforce in the following sectors: disability, aged care, health, mental health, family and youth services, and early childhood education and care was conducted. Embase and MEDLINE databases were searched, and studies published between January 2015 and November 2022 were included. We used the Quality Assessment tool for Quantitative Studies and the PEDro tools to evaluate study quality. Results: 5594 articles were initially screened and after applying the inclusion and exclusion criteria, 30 studies were included in the rapid review. Studies most frequently reported on the professional nursing, medical and allied health workforces. Some studies focused on the single domain of care worker education (n = 11) while most focused on multiple domains that combined education with recruitment strategies, retention strategies or a focus on worker safety. Study quality was comparatively low with a median PEDro score of 5/10, and 77% received a weak rating on the Quality Assessment tool for Quantitative Studies. Four new workforce strategies emerged; early career rural recruitment supports rural retention; workload management is essential for workforce well-being; learning must be contextually relevant; and there is a need to differentiate recruitment, retention, and education strategies for different professional health and care workforce categories as needs vary. Conclusions: Given the critical importance of recruiting and retaining a strong health and care workforce, there is an immediate need to develop a cohesive strategy to address workforce shortfalls. This paper presents initial evidence on different interventions to address this need, and to inform care workforce recruitment and retention.

Hypnosis Antenatal Training for Childbirth (HATCh): a randomised controlled trial [NCT00282204]

BACKGROUND: Although medical interventions play an important role in preserving lives and maternal comfort they have become increasingly routine in normal childbirth. This may increase the risk of associated complications and a less satisfactory birth experience. Antenatal hypnosis is associated with a reduced need for pharmacological interventions during childbirth. This trial seeks to determine the efficacy or otherwise of antenatal group hypnosis preparation for childbirth in late pregnancy. METHODS/DESIGN: A single centre, randomised controlled trial using a 3 arm parallel group design in the largest tertiary maternity unit in South Australia. Group 1 participants receive antenatal hypnosis training in preparation for childbirth administered by a qualified hypnotherapist with the use of an audio compact disc on hypnosis for re-enforcement; Group 2 consists of antenatal hypnosis training in preparation for childbirth using an audio compact disc on hypnosis administered by a nurse with no training in hypnotherapy; Group 3 participants continue with their usual preparation for childbirth with no additional intervention. Women > 34 and < 39 weeks gestation, planning a vaginal birth, not in active labour, with a singleton, viable fetus of vertex presentation, are eligible to participate. Allocation concealment is achieved using telephone randomisation. Participants assigned to hypnosis groups commence hypnosis training as near as possible to 37 weeks gestation. Treatment allocations are concealed from treating obstetricians, anaesthetists, midwives and those personnel collecting and analysing data. Our sample size of 135 women/group gives the study 80% power to detect a clinically relevant fall of 20% in the number of women requiring pharmacological analgesia – the primary endpoint. We estimate that approximately 5–10% of women will deliver prior to receiving their allocated intervention. We plan to recruit 150 women/group and perform sequential interim analyses when 150 and 300 participants have been recruited. All participant data will be analysed, by a researcher blinded to treatment allocation, according to the "Intention to treat" principle with comprehensive pre-planned cost- benefit and subgroup analyses. DISCUSSION: If effective, hypnosis would be a simple, inexpensive way to improve the childbirth experience, reduce complications associated with pharmacological interventions, yield cost savings in maternity care, and this trial will provide evidence to guide clinical practice
