Long read review: drug dealer, MD: how doctors were duped, patients got hooked and why it’s so hard to stop by Anna Lembke

In Drug Dealer, MD: How Doctors were Duped, Patients got Hooked and Why it’s So Hard to Stop, Anna Lembke sheds light on the rise of prescription drug addiction in the USA, fuelled in part by the actions of doctors and the structure of the US healthcare system. As the book illuminates the causes and drivers behind the increasing everyday reliance on prescribed opioids, Thomas Christie Williams ponders whether this situation could hit countries such as the UK in the coming future

Book review: metrics: what counts in global health edited by Vincanne Adams

Metrics: What Counts in Global Health, a collection of essays edited by Vincanne Adams, looks at how the preoccupation with health metrics is distorting the way that healthcare is being funded and delivered, particularly in the Global South. Thomas Christie Williams hopes that the volume will encourage policymakers and researchers to reflect upon the potential consequences of ‘the numbers game’ for both patients and practitioners

Book review: metric power by David Beer

In Metric Power, David Beer examines the intensifying role that metrics play in our everyday lives, from healthcare provision to our interactions with friends and family, within the context of the so-termed data revolution. This is a book that illustrates our growing implication in, and arguable acquiescence to, an increasingly quantified world, but, Thomas Christie Williams asks, where do we locate resistance

The impact of NHS based primary care complementary therapy services on health outcomes and NHS costs: a review of service audits and evaluations

<p>Abstract</p> <p>Background</p> <p>The aim of this study was to review evaluations and audits of primary care complementary therapy services to determine the impact of these services on improving health outcomes and reducing NHS costs. Our intention is to help service users, service providers, clinicians and NHS commissioners make informed decisions about the potential of NHS based complementary therapy services.</p> <p>Methods</p> <p>We searched for published and unpublished studies of NHS based primary care complementary therapy services located in England and Wales from November 2003 to April 2008. We identified the type of information included in each document and extracted comparable data on health outcomes and NHS costs (e.g. prescriptions and GP consultations).</p> <p>Results</p> <p>Twenty-one documents for 14 services met our inclusion criteria. Overall, the quality of the studies was poor, so few conclusions can be made. One controlled and eleven uncontrolled studies using SF36 or MYMOP indicated that primary care complementary therapy services had moderate to strong impact on health status scores. Data on the impact of primary care complementary therapy services on NHS costs were scarcer and inconclusive. One controlled study of a medical osteopathy service found that service users did not decrease their use of NHS resources.</p> <p>Conclusion</p> <p>To improve the quality of evaluations, we urge those evaluating complementary therapy services to use standardised health outcome tools, calculate confidence intervals and collect NHS cost data from GP medical records. Further discussion is needed on ways to standardise the collection and reporting of NHS cost data in primary care complementary therapy services evaluations.</p

Collaborative futures:discursive realignments in austere times

This paper explores the future of collaboration in an era of austerity. Boundary object theory provides a framework to examine the significance and role of four key discourses in collaboration – efficiency, effectiveness, responsiveness and cultural performance. Crisis provides a way of examining how and in what ways discourses realign. The exploration of discourses aids critical analysis of collaboration across sectoral, geographical and disciplinary boundaries, highlighting the importance of understanding the contextual roots of collaboration theory and practice, and the implications of local/global dynamics

Genome sequence of an Australian kangaroo, Macropus eugenii, provides insight into the evolution of mammalian reproduction and development.

BACKGROUND: We present the genome sequence of the tammar wallaby, Macropus eugenii, which is a member of the kangaroo family and the first representative of the iconic hopping mammals that symbolize Australia to be sequenced. The tammar has many unusual biological characteristics, including the longest period of embryonic diapause of any mammal, extremely synchronized seasonal breeding and prolonged and sophisticated lactation within a well-defined pouch. Like other marsupials, it gives birth to highly altricial young, and has a small number of very large chromosomes, making it a valuable model for genomics, reproduction and development. RESULTS: The genome has been sequenced to 2 × coverage using Sanger sequencing, enhanced with additional next generation sequencing and the integration of extensive physical and linkage maps to build the genome assembly. We also sequenced the tammar transcriptome across many tissues and developmental time points. Our analyses of these data shed light on mammalian reproduction, development and genome evolution: there is innovation in reproductive and lactational genes, rapid evolution of germ cell genes, and incomplete, locus-specific X inactivation. We also observe novel retrotransposons and a highly rearranged major histocompatibility complex, with many class I genes located outside the complex. Novel microRNAs in the tammar HOX clusters uncover new potential mammalian HOX regulatory elements. CONCLUSIONS: Analyses of these resources enhance our understanding of marsupial gene evolution, identify marsupial-specific conserved non-coding elements and critical genes across a range of biological systems, including reproduction, development and immunity, and provide new insight into marsupial and mammalian biology and genome evolution

Interventions for treating depression after stroke

Background: Depression is an important consequence of stroke that impacts on recovery yet is often not detected or inadequately treated. This is an update of a Cochrane review first published in 2004. Objectives: To determine whether pharmaceutical, psychological, or electroconvulsive treatment (ECT) of depression in patients with stroke can improve outcome. Search strategy: We searched the trials registers of the Cochrane Stroke Group (last searched October 2007) and the Cochrane Depression Anxiety and Neurosis Group (last searched February 2008). In addition, we searched the Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 1, 2008), MEDLINE (1966 to May 2006), EMBASE (1980 to May 2006), CINAHL (1982 to May 2006), PsycINFO (1967 to May 2006) and other databases. We also searched reference lists, clinical trials registers, conference proceedings and dissertation abstracts, and contacted authors, researchers and pharmaceutical companies. Selection criteria: Randomised controlled trials comparing pharmaceutical agents with placebo, or various forms of psychotherapy or ECT with standard care (or attention control), in patients with stroke, with the intention of treating depression. Data collection and analysis: Two review authors selected trials for inclusion and assessed methodological quality; three review authors extracted, cross-checked and entered data. Primary analyses were the prevalence of diagnosable depressive disorder at the end of treatment. Secondary outcomes included depression scores on standard scales, physical function, death, recurrent stroke and adverse effects. Main results: Sixteen trials (17 interventions), with 1655 participants, were included in the review. Data were available for 13 pharmaceutical agents, and four trials of psychotherapy. There were no trials of ECT. The analyses were complicated by the lack of standardised diagnostic and outcome criteria, and differing analytic methods. There was some evidence of benefit of pharmacotherapy in terms of a complete remission of depression and a reduction (improvement) in scores on depression rating scales, but there was also evidence of an associated increase in adverse events. There was no evidence of benefit of psychotherapy. Authors' conclusions: A small but significant effect of pharmacotherapy (not psychotherapy) on treating depression and reducing depressive symptoms was found, as was a significant increase in adverse events. More research is required before recommendations can be made about the routine use of such treatments

The genomes of two key bumblebee species with primitive eusocial organization

Background: The shift from solitary to social behavior is one of the major evolutionary transitions. Primitively eusocial bumblebees are uniquely placed to illuminate the evolution of highly eusocial insect societies. Bumblebees are also invaluable natural and agricultural pollinators, and there is widespread concern over recent population declines in some species. High-quality genomic data will inform key aspects of bumblebee biology, including susceptibility to implicated population viability threats. Results: We report the high quality draft genome sequences of Bombus terrestris and Bombus impatiens, two ecologically dominant bumblebees and widely utilized study species. Comparing these new genomes to those of the highly eusocial honeybee Apis mellifera and other Hymenoptera, we identify deeply conserved similarities, as well as novelties key to the biology of these organisms. Some honeybee genome features thought to underpin advanced eusociality are also present in bumblebees, indicating an earlier evolution in the bee lineage. Xenobiotic detoxification and immune genes are similarly depauperate in bumblebees and honeybees, and multiple categories of genes linked to social organization, including development and behavior, show high conservation. Key differences identified include a bias in bumblebee chemoreception towards gustation from olfaction, and striking differences in microRNAs, potentially responsible for gene regulation underlying social and other traits. Conclusions: These two bumblebee genomes provide a foundation for post-genomic research on these key pollinators and insect societies. Overall, gene repertoires suggest that the route to advanced eusociality in bees was mediated by many small changes in many genes and processes, and not by notable expansion or depauperation

The clinical effectiveness and cost-effectiveness of treatments for idiopathic pulmonary fibrosis: a systematic review and economic evaluation

BACKGROUND: Idiopathic pulmonary fibrosis (IPF) is a life-limiting lung disease that generally affects people over 60 years old. The main symptoms are shortness of breath and cough, and as the disease progresses there is a considerable impact on day-to-day life. Few treatments are currently available. OBJECTIVES: To conduct a systematic review of clinical effectiveness and an analysis of cost-effectiveness of treatments for IPF based on an economic model informed by systematic reviews of cost-effectiveness and quality of life. DATA SOURCES: Eleven electronic bibliographic databases, including MEDLINE, EMBASE, Web of Science, and The Cochrane Library and the Centre for Reviews and Dissemination databases, were searched from database inception to July 2013. Reference lists of relevant publications were also checked and experts consulted. METHODS: Two reviewers independently screened references for the systematic reviews, extracted and checked data from the included studies and appraised their risk of bias. An advisory group was consulted about the choice of interventions until consensus was reached about eligibility. A narrative review with meta-analysis was undertaken, and a network meta-analysis (NMA) was performed. A decision-analytic Markov model was developed to estimate cost-effectiveness of pharmacological treatments for IPF. Parameter values were obtained from NMA and systematic reviews. Univariate and probabilistic sensitivity analyses were undertaken. The model perspective is NHS and Personal Social Services, and discount rate is 3.5% for costs and health benefits. RESULTS: Fourteen studies were included in the review of clinical effectiveness, of which one evaluated azathioprine, three N-acetylcysteine (NAC) (alone or in combination), four pirfenidone, one BIBF 1120, one sildenafil, one thalidomide, two pulmonary rehabilitation, and one a disease management programme. Study quality was generally good, with a low risk of bias. The current evidence suggests that some treatments appear to be clinically effective. The model base-case results show increased survival for five pharmacological treatments, compared with best supportive care, at increased cost. General recommendations cannot be made of their cost-effectiveness owing to limitations in the evidence base. LIMITATIONS: Few direct comparisons of treatments were identified. An indirect comparison through a NMA was performed; however, caution is recommended in the interpretation of these results. In relation to the economic model, there is an assumption that pharmacological treatments have a constant effect on the relative rate of per cent predicted forced vital capacity decline. CONCLUSIONS: Few interventions have any statistically significant effect on IPF and a lack of studies on palliative care approaches was identified. Research is required into the effects of symptom control interventions, in particular pulmonary rehabilitation and thalidomide. Other research priorities include a well-conducted randomised controlled trial on inhaled NAC therapy and an updated evidence synthesis once the results of ongoing studies are reported
