Peer researchers' experiences of a co-produced research project on supported decision-making.

BACKGROUND: Making decisions about your own life is a key aspect of independence, freedom, human rights and social justice. There are disabled people who, without support, would be assessed as incapable of making certain decisions but with the appropriate support are capable of making those decisions and so to not provide that support infringes their rights, undermines their autonomy and reinforces their exclusion from society. However, there is limited research evidence available about disabled people's experiences of the range of approaches provided to support decision-making. This article will explore the experiences of four peer researchers who co-produced a research project on how people have, or have not been, supported to make their own decisions. Two of the peer researchers have experience of mental health problems and two are people with an intellectual disability. The article refers to peer research because its subject matter is the relevant lived experience of people. Peer research is therefore an approach within the broader areas of participatory research and co-production. METHODS: The peer researchers interviewed 21 people with mental health problems and 20 people with an intellectual disability to gain an in-depth understanding of their experiences and preferences for how decision-making should be supported. Peer researcher experiences at each stage of the study from design to analysis were explored using data collected from the peer researchers via blogs written at early stages of the study, discussions at team meetings as the fieldwork progressed and at a final workshop at the end of the study which gave the peer researchers the opportunity to focus on their overall reflections of being a peer researcher. The article also discusses motivations to undertake the peer research role, the process of co-production and the challenges negotiated during the study. RESULTS: The peer researchers reported a number of positive effects of being involved in the research project which included improvements in skills and self-confidence. CONCLUSION: The peer researchers' involvement challenged assumptions about the inability of people with an intellectual disability and/or mental health problems to participate proactively in a research project whilst also highlighting the importance of training for all team members.

Making your own decisions is important. There are disabled people who need support to make some decisions. Supporting disabled people to make decisions is needed so that they are not excluded from society. However, the evidence is limited on disabled people's experiences of how best to support decision-making. This article will explore the experiences of four researchers with mental health problems or an intellectual disability who worked with other researchers to conduct a project on how people have, or have not been, supported to make their own decisions. These researchers are called peer researchers. The peer researchers interviewed 21 people with mental health problems and 20 people with an intellectual disability. These interviews were conducted in order to gain a detailed understanding of the experiences and preferences for how decision-making should be supported. Blogs written by the peer researchers, discussions in team meetings and a workshop at the end of the study enabled the peer researchers to reflect on their experiences. The peer researchers reported a number of positive effects of being involved in the research project which included improvements in skills and self-confidence. The peer researchers' involvement challenged assumptions about the inability of people with an intellectual disability and/or mental health problems to participate in a research project whilst also highlighting the importance of training for all team members.

A Guide to the Postmortem Investigation of Starvation in Adults.

ABSTRACT: Starvation is a rare cause of death in developed countries and is a complex multifaceted pathological process. To complicate the forensic investigation of starvation further, many medical conditions independent of starvation may cause wasting. This article provides one of the first comprehensive guides to the postmortem investigation of starvation in adults, with reference tables on organ-specific macroscopic and microscopic features, as well as features for excluding alternative causes of wasting. The eclectic literature on this complex topic is summarized in an accessible and easily referenced format, including mechanisms of death and ancillary postmortem investigations.

Key components of supporting and assessing decision making ability.

People's ability to make decisions may be impaired for a wide range of reasons, including by mental health problems and learning disabilities. Individual autonomy, the ability to make decisions about our own lives, is a fundamental tenet of democratic societies. This has been reinforced by laws governing substitute and supported decision making and most significantly by the United Nations Convention on the Rights of Persons with Disabilities (UNCRPD). Article 12 of the UNCRPD requires everyone to have equal recognition before the law and, to achieve this, the necessary support and safeguards must be available. There has been considerable debate about the important theoretical and philosophical issues involved and growing research about the practice complexities of supporting and assessing decision making ability or mental capacity. This article aims to present some of the key components of the support and assessment process to inform further service development and training in this area. The key components were identified as part of a qualitative, participatory research project which explored the decision making experiences of people with mental health problems and/or learning disabilities. The conventional approach to the assessment of capacity is to consider four main components, whether the person is able to: understand, retain, use and weigh, and communicate the information needed to make the decision at that time. The findings from this research study suggest that people generally don't usually talk about their experiences of decision making in terms of these four components and approaches to supporting people to make decisions don't necessarily break the support down to explicitly address the assessment process. However, considering support for all aspects of the functional test may be helpful to ensure it is as comprehensive as possible. The challenges involved in providing effective support and assessing decision making ability are discussed and the article concludes with some of the implications for training, service development and practice.

Service users' experiences and views of support for decision-making.

This article presents the findings from a qualitative, participatory research project which explored how people with intellectual disabilities and/or mental health problems have, or have not been, supported to make their own decisions. The aim of the research is to help inform how supported decision-making, as required by Article 12 of the UN Convention on the Rights of Persons with Disabilities, can be effectively operationalised. The project provides an overview of experiences of support as well as identifying which supports are valued. It was conducted between July 2017 and July 2018 and was a partnership between disabled people, service providers and a University. It involved peer researchers interviewing 41 people with mental health problems and/or intellectual disabilities, in community settings, about their experiences and views of support. The key findings include that decision-making is a central aspect of people's lives. Participants discussed the positive role which decision-making can have but also how it felt when they were not supported to make their own decisions. Participants said that there were three main things that make decision-making harder: the type of decision; the role of other people; and what the outcome might be. Time was consistently identified as a very important factor. In terms of support, people said that they would like: practical support including more accessible information; emotional support including someone to talk to; and sometimes the options to choose from. There was very little mention of existing, more formal processes of support such as advance decisions or care planning. The peer researcher aspect of the project was valued by participants. The main implications of the research are for how support for decision-making should be provided including the need for an individualised approach as the support needed varies across decisions, time and people.

Adaptation-based resistance to siderophore-conjugated antibacterial agents by Pseudomonas aeruginosa.

Multidrug resistance in Gram-negative bacteria has become so threatening to human health that new antibacterial platforms are desperately needed to combat these deadly infections. The concept of siderophore conjugation, which facilitates compound uptake across the outer membrane by hijacking bacterial iron acquisition systems, has received significant attention in recent years. While standard in vitro MIC and resistance frequency methods demonstrate that these compounds are potent, broad-spectrum antibacterial agents whose activity should not be threatened by unacceptably high spontaneous resistance rates, recapitulation of these results in animal models can prove unreliable, partially because of the differences in iron availability in these different methods. Here, we describe the characterization of MB-1, a novel siderophore-conjugated monobactam that demonstrates excellent in vitro activity against Pseudomonas aeruginosa when tested using standard assay conditions. Unfortunately, the in vitro findings did not correlate with the in vivo results we obtained, as multiple strains were not effectively treated by MB-1 despite having low MICs. To address this, we also describe the development of new in vitro assays that were predictive of efficacy in mouse models, and we provide evidence that competition with native siderophores could contribute to the recalcitrance of some P. aeruginosa isolates in vivo.

Discovery of Dap-3 polymyxin analogues for the treatment of multidrug-resistant Gram-negative nosocomial infections.

We report novel polymyxin analogues with improved antibacterial in vitro potency against polymyxin resistant recent clinical isolates of Acinetobacter baumannii and Pseudomonas aeruginosa . In addition, a human renal cell in vitro assay (hRPTEC) was used to inform structure-toxicity relationships and further differentiate analogues. Replacement of the Dab-3 residue with a Dap-3 in combination with a relatively polar 6-oxo-1-phenyl-1,6-dihydropyridine-3-carbonyl side chain as a fatty acyl replacement yielded analogue 5x, which demonstrated an improved in vitro antimicrobial and renal cytotoxicity profiles relative to polymyxin B (PMB). However, in vivo PK/PD comparison of 5x and PMB in a murine neutropenic thigh model against P. aeruginosa strains with matched MICs showed that 5x was inferior to PMB in vivo, suggesting a lack of improved therapeutic index in spite of apparent in vitro advantages.

Novel monobactams utilizing a siderophore uptake mechanism for the treatment of gram-negative infections.

Novel siderophore-linked monobactams with in vitro and in vivo anti-microbial activity against MDR Gram-negative pathogens are described.

Preclinical characterization of PF-00868554, a potent nonnucleoside inhibitor of the hepatitis C virus RNA-dependent RNA polymerase.

PF-00868554 is a nonnucleoside inhibitor of the hepatitis C virus (HCV) RNA polymerase, which exerts its inhibitory effect by binding to the thumb base domain of the protein. It is a potent and selective inhibitor, with a mean 50% inhibitory concentration of 0.019 microM against genotype 1 polymerases and a mean 50% effective concentration (EC(50)) of 0.075 microM against the genotype 1b-Con1 replicon. To determine the in vitro antiviral activity of PF-00868554 against various HCV strains, a panel of chimeric replicons was generated, in which polymerase sequences derived from genotype 1a and 1b clinical isolates were cloned into the 1b-Con1 subgenomic reporter replicon. Our results indicate that PF-00868554 has potent in vitro antiviral activity against a majority (95.8%) of genotype 1a and 1b replicons, with an overall mean EC(50) of 0.059 microM. PF-00868554 showed no cytotoxic effect in several human cell lines, up to the highest concentration evaluated (320 microM). Furthermore, the antiviral activity of PF-00868554 was retained in the presence of human serum proteins. An in vitro resistance study of PF-00868554 identified M423T as the predominant resistance mutation, resulting in a 761-fold reduction in susceptibility to PF-00868554 but no change in susceptibility to alpha interferon and a polymerase inhibitor that binds to a different region. PF-00868554 also showed good pharmacokinetic properties in preclinical animal species. Our results demonstrate that PF-00868554 has potent and broad-spectrum antiviral activity against genotype 1 HCV strains, supporting its use as an oral antiviral agent in HCV-infected patients.

"Med-X": a medical examiner surveillance model for bioterrorism and infectious disease mortality.

We created a model surveillance system (Med-X) designed to enable medical examiners and coroners to recognize fatal infections of public health importance and deaths due to bioterrorism. All individuals who died in New Mexico and fell under medical examiner jurisdiction between November 23, 2000, and November 22, 2002, were prospectively evaluated using sets of surveillance symptoms and autopsy-based pathologic syndromes. All infectious disease deaths were evaluated to identify the specific causative agent. Of 6104 jurisdictional cases, 250 (4.1%) met Med-X criteria, of which 141 (56.4%) had a target pathologic syndrome. Ultimately, 127 (51%) of the 250 cases were due to infections. The causative organism was identified for 103 (81%) of the infectious disease deaths, of which 60 (58.3%) were notifiable conditions in New Mexico. Flu-like symptoms, fever and respiratory symptoms, and encephalopathy or new-onset seizures had predictive values positive for fatal infections of 65%, 72%, and 50%, respectively, and are useful as autopsy performance criteria. Before the development of surveillance criteria, 37 (14.8%) of the cases ordinarily would not have been autopsied resulting in a 1% increase in autopsy workload. Med-X is an effective method of detecting infectious disease deaths among medical examiner cases. Uniform criteria for performing medical examiner autopsies and reporting cases to public health authorities enhance surveillance for notifiable infectious diseases and increase the likelihood of recognizing deaths related to bioterrorism.

Strychnine overdose following ingestion of gopher bait.

A 52-year-old male was discovered supine on his bed in a state of early decomposition. Commercial strychnine-treated gopher pellets were found in the home, and suicide notes were present at the scene. Biological fluids and tissues were tested for basic, acidic, and neutral drugs using gas chromatography-mass spectrometry. Concentrations of strychnine in heart and femoral blood were 0.96 and 0.31 mg/L, respectively. Vitreous fluid, bile, urine, liver, and brain specimens contained 0.36 mg/L, 1.17 mg/L, 2.92 mg/L, 4.59 mg/kg, and 0.86 mg/kg strychnine, respectively. No other drugs were detected in any of the samples. The cause of death was attributed to rodenticide poisoning, and the manner of death was suicide.
