The initiation and administration of drugs for advanced life support by critical care nurses in the absence of a medical practitioner

Current legislation does not permit the administration of first line resuscitation medications by suitably qualified Division 1 registered nurses (RNs) in the absence of a medical officer. This omission by the Drugs,  Poisons and Controlled Substances Act 1981 (Vic) and the Drugs, Poisons and The Controlled Substances Regulations 1995 (Vic) leaves many critical care nurses in a vulnerable legal position.

The primary aim of this study was to gauge the view of critical care nurses with respect to lobbying for change to the current legislation. In addition, the study aimed to explore and describe the educational preparation, practice perceptions and experiences of RNs working in critical care regarding cardiopulmonary resuscitation and the administration of first line advanced life support (ALS) medications in the absence of a medical officer. It was anticipated that data collected would demonstrate some of the dilemmas associated with the initiation and administration of ALS medications for practising critical care nurses and could be used to inform controlling bodies in order for them to gain an appreciation of the issues facing critical care nurses during resuscitation.

A mailout survey was sent to all members of the Victorian Branch of the Australian College of Critical Care Nurses (ACCCN). The results showed that the majority of nurses underwent an annual ALS assessment and had current ALS accreditation. Nurses indicated that they felt educationally prepared and were confident to manage cardiopulmonary resuscitation without a medical officer; indeed, the majority had done so. The differences in practice issues for metropolitan, regional and rural nurses were highlighted. There is therefore clear evidence to suggest that legislative amendments are appropriate and necessary, given the time critical nature of cardiopulmonary arrest. There was overwhelming support for ACCCN Vic. Ltd to lobby the Victorian government for changes to the law.

Emerging trends in the use of drugs to manage the challenging behaviour of people with intellectual disability

Background Concerns about the pharmacological management of the behaviour of individuals with intellectual disability have resulted in the development of legislative and procedural controls.
Method This Australian study provided a comparison of 873 reported cases where drugs were administered to manage behaviour in March 2000, with 762 cases reported in March 1993. Drug use in individuals who remained medicated across time (n = 316: recurrent sample) was also compared with those who were reported only in 1993 (n = 329: limited sample).
Results A small decrease in the proportion of individuals who were reported to have received medication was evident over time (from 5% to 4.5% of total population). However, this was accompanied by an increase in drug diversity and interclass polypharmacy. An increase in antidepressant use was evident (from 7.4% to 13.8% of reported drugs), and there was a trend towards greater reporting of medication for acute behavioural problems and medication use with children. Greater use of antipsychotic drugs was evident in individuals who remained medicated across time compared with those who did not.
Conclusions The findings suggest the need for continuous research into practice. The fact that many individuals receive medication over long periods makes it incumbent on service providers to engage in regular, comprehensive and individualized review and evaluation of medication regimes.

Systematic review and meta-analysis of evidence for increasing numbers of drugs in antiretroviral combination therapy

Objective: To assess the evidence for the effectiveness of increasing numbers of drugs in antiretroviral combination therapy.

Design: Systematic review, meta-analysis, and meta-regression of fully reported randomised controlled trials. All studies included compared quadruple versus triple therapy, triple versus double therapy, double versus monotherapy, or monotherapy versus placebo or no treatment.

Participants: Patients with any stage of HIV infection who had not received antiretroviral therapy.

Main outcome measures: Changes in disease progression or death (clinical outcomes); CD4 count and plasma viral load (surrogate markers).
Search strategy: Six electronic databases, including Medline, Embase, and the Cochrane Library, searched up to February 2001.

Results: 54 randomised controlled trials, most of good quality, with 66 comparison groups were included in the analysis. For both the clinical outcomes and surrogate markers, combinations with up to and including three (triple therapy) were progressively and significantly more effective. The odds ratio for disease progression or death for triple therapy compared with double therapy was 0.6 (95% confidence interval 0.5 to 0.8). Heterogeneity in effect sizes was present in many outcomes but was largely related to the drugs used and trial quality.

Conclusions: Evidence from randomised controlled trials supports the use of triple therapy. Research is needed on the effectiveness of quadruple therapies and the relative effectiveness of specific combinations of drugs.

Disentangling the stigma of HIV/AIDS from the stigmas of drugs use, commercial sex and commercial blood donation - a factorial survey of medical students in China

Background
HIV/AIDS related stigma interferes with the provision of appropriate care and support for people living with HIV/AIDS. Currently, programs to address the stigma approach it as if it occurs in isolation, separate from the co-stigmas related to the various modes of disease transmission including injection drug use (IDU) and commercial sex (CS). In order to develop better programs to address HIV/AIDS related stigma, the inter-relationship (or 'layering') between HIV/AIDS stigma and the co-stigmas needs to be better understood. This paper describes an experimental study for disentangling the layering of HIV/AIDS related stigmas.

Methods
The study used a factorial survey design. 352 medical students from Guangzhou were presented with four random vignettes each describing a hypothetical male. The vignettes were identical except for the presence of a disease diagnosis (AIDS, leukaemia, or no disease) and a co-characteristic (IDU, CS, commercial blood donation (CBD), blood transfusion or no co-characteristic). After reading each vignette, participants completed a measure of social distance that assessed the level of stigmatising attitudes.

Results
Bivariate and multivariable analyses revealed statistically significant levels of stigma associated with AIDS, IDU, CS and CBD. The layering of stigma was explored using a recently developed technique. Strong interactions between the stigmas of AIDS and the co-characteristics were also found. AIDS was significantly less stigmatising than IDU or CS. Critically, the stigma of AIDS in combination with either the stigmas of IDU or CS was significantly less than the stigma of IDU alone or CS alone.

Conclusion
The findings pose several surprising challenges to conventional beliefs about HIV/AIDS related stigma and stigma interventions that have focused exclusively on the disease stigma. Contrary to the belief that having a co-stigma would add to the intensity of stigma attached to people with HIV/AIDS, the findings indicate the presence of an illness might have a moderating effect on the stigma of certain co-characteristics like IDU. The strong interdependence between the stigmas of HIV/AIDS and the co-stigmas of IDU and CS suggest that reducing the co-stigmas should be an integral part of HIV/AIDS stigma intervention within this context.

Disorder and the body of drugs : addiction, consumption, control, and city space

Different cultures and the specific culture manifested within them are intrinsically linked to addiction in a complex fashion which has a long history. For important thinkers, such as Nietzsche, addiction actually embodies human culture, rendering addiction and culture inseparable. This is clearly seen within the Western world’s addiction to the consumption of material goods and the damage that results.

Utopia has often become dystopia. Not only is an understanding of addiction key to understanding culture but to an understanding of the very act thinking itself and the way of being in the world. Addiction raises key philosophical questions, such as: do people really have a choice in their behavior, and what governs them; is it free will or predetermination? Is it biology or environment is it the external world or the internal that drives addiction, or a complex combination of both?

In a contemporary context the media frenzy around celebrity addiction continually fuels public debate in this area, and this book deepens the understanding of addiction within this contentious context. This book addresses a key concern over how addiction became the norm, and it seeks to understand its dominance comprehensively. How did it come to pass that not being an addict was a transgressive act and way of being?

While there has been a great deal of debate about addiction utilizing the discourse of individual and often competing disciplines such as biology and psychology, little attention has been paid to the cultural aspects of addiction. The innovative approach taken by this book is to offer insights into this complex area through a contemporary methodology that covers diverse interrelated areas. Drawing on different disciplines, offering deeper insights, from the analysis of music lyrics to empirical social science and anthropological work in AA groups in Mexico and the portrayal of the “addiction’ to therapy in film and television, amongst other areas, this book addresses the need for a more comprehensive approach.

Academic analysis is also given to the discourse on celebrity culture and addiction. A contemporary fusion of the humanities and the social sciences is the best way forward to tackle this subject and move the debate on. The focus of this study is an innovative interdisciplinary and intercultural approach to addiction, from the social sciences to the humanities, including cultural studies, film and media studies, and literary studies. Areas that have been overlooked, such as lost women’s writings, are examined, in addition to comics, popular film and television, and the work of AA groups.

This edited collection is the first study to provide such a comprehensive analysis of the cultures of addiction. Traversing cultures across the globe, including Asia, Central America, as well as Europe and America, this book opens up the debate in addiction studies and cultural studies. The important insights the book delivers helps to answer questions such as: In what way can Deleuze further the understanding of addiction through the analysis of rock lyrics? How does anthropology improve the understanding of AA groups? How can cultural studies deepen knowledge on the “addiction” to therapy? These are just some of the vast array of areas this book covers. Other areas include the condemnation of “addiction” to comic reading through an historical examination, violence in popular culture, and lost women’s writing on addiction. No other book has such depth and contemporary breadth.

Cultures of Addiction is an important book for those taking cultural studies courses across a range of interrelated disciplines, including English and literary studies, history, American studies, and film and media studies. This will be invaluable to library collections in these fields and beyond in the social sciences, and specifically in addiction studies and psychology.

Out of the shadows: a discussion on law reform for the prevention of financial abuse of older people

Financial abuse of older people too often lives ‘in the shadows, hidden by fear and shame’. This and the protective love between family members can screen changes that are critical to an older person’s financial and living arrangements. Rather than a single event, it is usually a series of well-intentioned but ill-considered financial acts, which at some point tips over into abuse interwoven with an intricate web of family relationships. Was a transfer of title or a loan to an adult child really misappropriation? Has thoughtlessness become undue influence or even theft? 

Abuse of power, oppression and the struggle for human rights in modern indonesian short fiction

 Across the 1990s, Indonesian writers used the short story genre to represent human rights abuses in Indonesia.These rights included freedom of speech, right to life and right to assembly. The short story had great impact, depicting dramatically both perpetrators and victims, and exposing the social, economic and political conditions which bred such abuses.

The use and abuse of 'community' and 'neighbourhood' within disability research: an exposé, clarification, and recommendation

Almost invariably in the disability literature, the terms 'neighbourhood' and 'community' are used as though they have some commonly understood meaning. They do not, and authors rarely offer a definition. This problem adds opacity to the literature describing people's living environment and the nature of their interaction with others living in the same area. This ambiguity becomes crucial to understanding when these terms are linked to other vague, but emotionally-charged words, such as 'inclusion' or 'integration'. This review presents some of the ways 'neighbourhood' and 'community' may be correctly employed. It also explores the theoretical basis for understanding how and why their use may be misleading. Finally, it is demonstrated that the assumed relevance of neighbourhood participation for life quality has been greatly exaggerated. We recommend that authors carefully define their use of these terms in order to facilitate understanding free from emotional bias.

Mechanism-based inhibition of cytochrome P450 3A4 by therapeutic drugs

Consistent with its highest abundance in humans, cytochrome P450 (CYP) 3A is responsible for the metabolism of about 60% of currently known drugs. However, this unusual low substrate specificity also makes CYP3A4 susceptible to reversible or irreversible inhibition by a variety of drugs. Mechanism-based inhibition of CYP3A4 is characterised by nicotinamide adenine dinucleotide phosphate hydrogen (NADPH)-, time- and concentration-dependent enzyme inactivation, occurring when some drugs are converted by CYP isoenzymes to reactive metabolites capable of irreversibly binding covalently to CYP3A4. Approaches using in vitro, in silico and in vivo models can be used to study CYP3A4 inactivation by drugs. Human liver microsomes are always used to estimate inactivation kinetic parameters including the concentration required for half-maximal inactivation (K(I)) and the maximal rate of inactivation at saturation (k(inact)).Clinically important mechanism-based CYP3A4 inhibitors include antibacterials (e.g. clarithromycin, erythromycin and isoniazid), anticancer agents (e.g. tamoxifen and irinotecan), anti-HIV agents (e.g. ritonavir and delavirdine), antihypertensives (e.g. dihydralazine, verapamil and diltiazem), sex steroids and their receptor modulators (e.g. gestodene and raloxifene), and several herbal constituents (e.g. bergamottin and glabridin). Drugs inactivating CYP3A4 often possess several common moieties such as a tertiary amine function, furan ring, and acetylene function. It appears that the chemical properties of a drug critical to CYP3A4 inactivation include formation of reactive metabolites by CYP isoenzymes, preponderance of CYP inducers and P-glycoprotein (P-gp) substrate, and occurrence of clinically significant pharmacokinetic interactions with coadministered drugs.Compared with reversible inhibition of CYP3A4, mechanism-based inhibition of CYP3A4 more frequently cause pharmacokinetic-pharmacodynamic drug-drug interactions, as the inactivated CYP3A4 has to be replaced by newly synthesised CYP3A4 protein. The resultant drug interactions may lead to adverse drug effects, including some fatal events. For example, when aforementioned CYP3A4 inhibitors are coadministered with terfenadine, cisapride or astemizole (all CYP3A4 substrates), torsades de pointes (a life-threatening ventricular arrhythmia associated with QT prolongation) may occur.However, predicting drug-drug interactions involving CYP3A4 inactivation is difficult, since the clinical outcomes depend on a number of factors that are associated with drugs and patients. The apparent pharmacokinetic effect of a mechanism-based inhibitor of CYP3A4 would be a function of its K(I), k(inact) and partition ratio and the zero-order synthesis rate of new or replacement enzyme. The inactivators for CYP3A4 can be inducers and P-gp substrates/inhibitors, confounding in vitro-in vivo extrapolation. The clinical significance of CYP3A inhibition for drug safety and efficacy warrants closer understanding of the mechanisms for each inhibitor. Furthermore, such inactivation may be exploited for therapeutic gain in certain circumstances.

A case study of child sexual abuse within a Church community

A case study is presented of child sexual assault within a church community. How does a church community deal with the accusation of an adolescent female that-as a 13-year old-she was sexually victimised and assaulted by her then 18-year old boyfriend, five years her senior? Practical and pastoral issues, as well as ethical and legal concerns are addressed. Consideration is also given to the theological context of the church environments in which the situations arise. The implications for victims, perpetrators, leaders, and the church community of our actions-and failure to take appropriate action-are described, along with recommendations for prevention, and best practice in dealing with the sexual abuse of minors within church communities.
