    Background and Aims: Despite a wealth of literature, the relationship between anxiety and alcohol use remains unclear. We examined whether (a) child and adolescent anxiety is positively or negatively associated with later alcohol use and disorders and (b) study characteristics explain inconsistencies in findings. Design and Setting: We conducted a systematic review of 51 prospective cohort studies from 11 countries. Three studies contributed to a meta-analysis. We searched PubMed, Scopus, Web of Science and PsycINFO databases, and studies were included if they met the following criteria: English language publication, human participants, anxiety exposure (predictor variable) in childhood or adolescence and alcohol outcome at least 6months later. Participants: Study sample sizes ranged from 110 to 11 157 participants. Anxiety exposure ages ranged from 3 to 24years, and alcohol outcome ages ranged from 11 to 42years. Measurements: Ninety-seven associations across 51 studies were categorized by anxiety exposure (generalized anxiety disorder, internalizing disorders, miscellaneous anxiety, obsessive compulsive disorder, panic disorder, separation anxiety disorder, social anxiety disorder and specific phobias) and alcohol use outcome (drinking frequency/quantity, binge drinking and alcohol use disorders). Findings: The narrative synthesis revealed some evidence for a positive association between anxiety and later alcohol use disorders. Associations of anxiety with later drinking frequency/quantity and binge drinking were inconsistent. Type and developmental period of anxiety, follow-up duration, sample size and confounders considered did not appear to explain the discrepant findings. The meta-analysis also showed no clear evidence of a relationship between generalized anxiety disorder and later alcohol use disorder (odds ratio=0.94, 95% confidence interval=0.47–1.87). Conclusions: Evidence to date is suggestive, but far from conclusive of a positive association between anxiety during childhood and adolescence and subsequent alcohol use disorder

    The role of nurses in alcohol and drug treatment services: a resource for commissioners, providers and clinicians

    Commissioners and providers of alcohol and drugs services need to respond to an increasingly complex need in the populations they serve1. This requires services to be competent in identifying and responding to a wide range of health and social care needs and be able to support people to access treatment for co-existing physical and mental health issues, to enable recovery. This resource has been written by the Royal College of Nursing, the Association of Nurses in Substance Abuse (ANSA), the National Substance Misuse Non-Medical Prescribing Forum, and Public Health England. It describes the many possible roles of nurses in alcohol and drug treatment in England. It is one of a series of PHE-supported briefings on the roles of professions working in alcohol and drug treatment services, in the community and in secondary care2,3,4 and should be read in conjunction with them. This resource is to assist commissioners and providers of specialist adult alcohol and drug treatment services to identify the right workforce to meet the needs of their local populations. It does not address the wider role of nurses across other areas of health and social care, such as midwives, who make a significant contribution to the care of people who misuse alcohol and drugs, and their families. It outlines: •the roles of nurses working in alcohol and drug treatment including the contribution they can make to health and social care outcomes•the added value nurses can bring to alcohol and drug treatment•the competencies and skills that should be expected of nurses working in alcohol and drug treatment •what is required to develop and maintain these competencies potential added value of nurses is determined by the level of experience and training. Experienced nurses will be able to provide advanced clinical interventions and respond to more complex physical and mental health needs. It is important that the roles of nurses are not considered in isolation, but as a key part of a multidisciplinary team, responding to locally identified need

    Addressing social representations in socio-technical transitions with the case of shale gas

    While sociologists of science and technology have long understoodtechnological diffusion and adoption as processes of social embed-ding, the psycho-social processes involved have received relativelylittle attention in the socio-technical transitions literature. Here weconsider the value of Moscovici’s social representations theory interms of its potential contribution to a theory of socio-technicalchange, the multi-level perspective (MLP). Using fracking-derivedshale gas as a technology case study and newspaper representa-tions of the technology in Poland, Germany and the UK as data,we address and illustrate connections between the processes ofanchoring and objectification that are central to social represen-tations theory and the socio-technical dynamics observed. In so doing, we set out an approach for further work on agency in the MLP and socio-technical change processes generally, informed by a social psychological approach that aligns with structuralist concepts

    Characterisation of aerotolerant forms of a robust chicken colonizing Campylobacter coli

    Campylobacter contaminated poultry meat is a major source of human foodborne illness. Campylobacter coli strain OR12 is a robust colonizer of chickens that was previously shown to outcompete and displace other Campylobacter strains from the chicken’s gastrointestinal tract. This strain is capable of aerobic growth on blood agar. Serial aerobic passage increased this aerotolerance as assessed by quantitative assays for growth and survival on solid media. Aerotolerance was also associated with increased peroxide stress resistance. Aerobic passage did not alter cellular morphology or motility or hinder the microaerobic growth rate. Colonization of broiler chickens by aerotolerant C. coli OR12 was significantly lower than the wild-type strain at 3 days after challenge but not by 7 days, suggesting adaptation had occurred. Bacteria recovered from chickens had retained their aerotolerance, indicating this trait is stable. Whole genome sequencing enabled comparison with the wild-type sequence. Twenty-three point mutations were present, none of which were in genes known to affect oxidative stress resistance. Insertions or deletions caused frame shifts in several genes including, phosphoglycerate kinase and the b subunit of pyruvate carboxylase that suggest modification of central and carbohydrate metabolism in response to aerobic growth. Other genes affected include those encoding putative carbonic anhydrase, motility accessory factor, filamentous haemagglutinin, and aminoacyl dipeptidase proteins. Aerotolerance has the potential to affect environmental success and survival. Increased environmental survival outside of the host intestinal tract may allow opportunities for transmission between hosts. Resistance to oxidative stress may equate to increased virulence by virtue of reduced susceptibility to oxidative free radicals produced by host immune responses. Finally, resistance to ambient atmospheric oxygen may allow increased survival on chicken skin, and therefore constitutes an increased risk to public health

    Social and professional influences on antimicrobial prescribing for doctors-in-training: a realist review.

    Get PDF
    Background: Antimicrobial resistance has led to widespread implementation of interventions for appropriate prescribing. However, such interventions are often adopted without an adequate understanding of the challenges facing doctors-in-training as key prescribers. Methods: The review followed a realist, theory-driven approach to synthesizing qualitative, quantitative and mixed-methods literature. Consistent with realist review quality standards, articles retrieved from electronic databases were systematically screened and analysed to elicit explanations of antimicrobial prescribing behaviours. These explanations were consolidated into a programme theory drawing on social science and learning theory, and shaped though input from patients and practitioners. Results: By synthesizing data from 131 articles, the review highlights the complex social and professional dynamics underlying antimicrobial prescribing decisions of doctors-in-training. The analysis shows how doctors-in-training often operate within challenging contexts (hierarchical relationships, powerful prescribing norms, unclear roles and responsibilities, implicit expectations about knowledge levels, uncertainty about application of knowledge in practice) where they prioritize particular responses (fear of criticism and individual responsibility, managing one's reputation and position in the team, appearing competent). These complex dynamics explain how and why doctors-in-training decide to: (i) follow senior clinicians' prescribing habits; (ii) take (or not) into account prescribing aids, advice from other health professionals or patient expectations; and (iii) ask questions or challenge decisions. This increased understanding allows for targeted tailoring, design and implementation of antimicrobial prescribing interventions. Conclusions: This review contributes to a better understanding of how antimicrobial prescribing interventions for doctors-in-training can be embedded more successfully in the hierarchical and inter-professional dynamics of different healthcare settings

    Potential for reducing inappropriate antibiotic prescribing in English primary care.

    Objectives: To identify and quantify inappropriate systemic antibiotic prescribing in primary care in England, and ultimately to determine the potential for reduction in prescribing of antibiotics. Methods: Primary care data from 2013-15 recorded in The Health Improvement Network (THIN) database were used. Potentially inappropriate prescribing events in the database were identified by: (i) comparing prescribing events against treatment guidelines; (ii) comparing actual proportions of consultations resulting in prescription for a set of conditions with the ideal proportions derived from expert opinion; and (iii) identifying high prescribers and their number of prescriptions above an age- and body-system-specific benchmark. Results: Applying the most conservative assumptions, 8.8% of all systemic antibiotic prescriptions in English primary care were identified as inappropriate, and in the least conservative scenario 23.1% of prescriptions were inappropriate. All practices had non-zero reduction potentials, ranging from 6.4% to 43.5% in the middle scenario. The four conditions that contributed most to inappropriate prescribing were sore throat (23.0% of identified inappropriate prescriptions), cough (22.2%), sinusitis (7.6%) and acute otitis media (5.7%). One-third of all antibiotic prescriptions lacked an informative diagnostic code. Conclusions: This work demonstrates (i) the existence of substantial inappropriate antibiotic prescribing and (ii) poor diagnostic coding in English primary care. All practices (not just the high prescribers) should engage in efforts to improve antimicrobial stewardship. Better diagnostic coding, more precise prescribing guidelines and a deeper understanding of appropriate long-term uses of antibiotics would allow identification of further potential for reductions

    Food Use and Health Effects of Soybean and Sunflower Oils

    Get PDF
    This review provides a scientific assessment of current knowledge of health effects of soybean oil (SBO) and sunflower oil (SFO). SBO and SFO both contain high levels of polyunsaturated fatty acids (PUFA) (60.8 and 69%, respectively), with a PUFA:saturated fat ratio of 4.0 for SBO and 6.4 for SFO. SFO contains 69% C18:2n-6 and less than 0.1% C18:3n-3, while SBO contains 54% C18:2n-6 and 7.2% C18:3n-3. Thus, SFO and SBO each provide adequate amounts of C18:2n-6, but of the two, SBO provides C18:3n-3 with a C18:2n-6:C18:3n-3 ratio of 7.1. Epidemiological evidence has suggested an inverse relationship between the consumption of diets high in vegetable fat and blood pressure, although clinical findings have been inconclusive. Recent dietary guidelines suggest the desirability of decreasing consumption of total and saturated fat and cholesterol, an objective that can be achieved by substituting such oils as SFO and SBO for animal fats. Such changes have consistently resulted in decreased total and low-density-lipoprotein cholesterol, which is thought to be favorable with respect to decreasing risk of cardiovascular disease. Also, decreases in high-density-lipoprotein cholesterol have raised some concern. Use of vegetable oils such as SFO and SBO increases C18:2n-6, decreases C20:4n-6, and slightly elevated C20:5n-3 and C22:6n-3 in platelets, changes that slightly inhibit platelet generation of thromboxane and ex vivo aggregation. Whether chronic use of these oils will effectively block thrombosis at sites of vascular injury, inhibit pathologic platelet vascular interactions associated with atherosclerosis, or reduce the incidence of acute vascular occlusion in the coronary or cerebral circulation is uncertain. Linoleic acid is needed for normal immune response, and essential fatty acid (EFA) deficiency impairs B and T cell-mediated responses. SBO and SFO can provide adequate linoleic acid for maintenance of the immune response. Excess linoleic acid has supported tumor growth in animals, an effect not verified by data from diverse human studies of risk, incidence, or progression of cancers of the breast and colon. Areas yet to be investigated include the differential effects of n-6- and n-3-containing oil on tumor development in humans and whether shorter-chain n-3 PUFA of plant origin such as found in SBO will modulate these actions of linoleic acid, as has been shown for the longer-chain n-3 PUFA of marine oil
