    Research has identified a subset of young people who feel unable to engage in mainstream education. Given the hard-to-reach nature of this group, their views on what has caused their isolation from others have received little focus in previous literature. The present study aimed to explore the experiences and views of a subset of young people seen within an inner London Pupil Referral Unit who were extremely socially withdrawn and unable to attend mainstream education. They were asked what they believe led them to their current situation, the impact of isolation, how their life is going and what they value. Key themes identified were the role of anxiety in withdrawal from education and the protective capacity of social contact, even via social media, in preventing negative outcomes of withdrawal. Sleep, health, education, family and social contact were identified as risk and protective factors and were also things participants identified as values. This research provides insight into potential ways to support young people in returning to mainstream education as well as ideas for preventative measures that may protect future generations from such extreme isolation. This research was conducted before the COVID-19 pandemic, but lessons learned bear relevance in current times

    Quasiclassical approaches to the generalized quantum master equation

    The formalism of the generalized quantum master equation (GQME) is an effective tool to simultaneously increase the accuracy and the efficiency of quasiclassical trajectory methods in the simulation of nonadiabatic quantum dynamics. The GQME expresses correlation functions in terms of a non-Markovian equation of motion, involving memory kernels that are typically fast-decaying and can therefore be computed by short-time quasiclassical trajectories. In this paper, we study the approximate solution of the GQME, obtained by calculating the kernels with two methods: Ehrenfest mean-field theory and spin-mapping. We test the approaches on a range of spin–boson models with increasing energy bias between the two electronic levels and place a particular focus on the long-time limits of the populations. We find that the accuracy of the predictions of the GQME depends strongly on the specific technique used to calculate the kernels. In particular, spin-mapping outperforms Ehrenfest for all the systems studied. The problem of unphysical negative electronic populations affecting spin-mapping is resolved by coupling the method with the master equation. Conversely, Ehrenfest in conjunction with the GQME can predict negative populations, despite the fact that the populations calculated from direct dynamics are positive definite

    Evaluation of a gender-sensitive physical activity programme for inactive men in Ireland: Protocol paper for a pragmatic controlled trial

    Get PDF
    The excess burden of ill-health, mortality and premature death experienced by many men, and poorer men in particular, across the developed world has prompted calls for the development of gender sensitised health related services for men. An emergent body of evidence indicates that successful public health work with men can be accomplished when it utilises elements with which men are familiar and secure. In particular, physical activity (PA) is proven here to be a useful ‘hook’ to engage men. ‘Men on the Move’ (MoM) is a community-based PA programme designed to engage inactive men to improve their overall health and well-being. The MoM programme was delivered by practitioner partnerships in diverse communities and among diverse groups of men under ‘real world’ conditions to assess both its efficacy and replicability with a view to scaling-up the programme nationally for population wide impact. Establishing appropriate protocols is critical when conducting research that translates into practice, is replicable in practice and can be disseminated at a population level. The purpose of this paper is to detail the protocols used in the design, implementation and evaluation of the MoM programme. Specifically, the process of engaging men in a community based PA intervention and sustaining that engagement over the 12 weeks and the protocols used to evaluate the impact of participation in MoM on biopsychosocial health up to 52 weeks will be outlined. If the intervention proves successful, gender-sensitive community based PA interventions for men could be a promising avenue to address their health needs. These findings may be of support to both practitioners endeavouring to engage men and others engaged in translational research to ensure their research translates to meaningful action in practice

    The impact of a gender-specific physical activity intervention on the fitness and fatness profile of men in Ireland

    Background: Amid increasing concerns about rising obesity rates and unhealthy lifestyle behaviours, physical activity (PA) is seen as a prophylactic to many chronic conditions affecting men. Men respond best to community-based PA programmes, using gender-specific promotional and delivery strategies. ‘Men on the Move’ (MOM) was developed on this basis and targeted inactive adult men in Ireland. Methods: Sedentary men (n=927; age=50.7±10.9yr; Weight=92.7±16.0kg; METS=6.06±2.13) were recruited across 8 counties; 4 ‘intervention group’ (IG; n=501), and 4 ‘comparison-in-waiting group’ (CG; n=426). The MOM programme involved structured group exercise twice weekly for 12 weeks, along with health-related workshops with the groups maintained up to 52W. Primary outcome measures (aerobic fitness, bodyweight and waist circumference (WC)) together with self-administered questionnaires were used to gather participant data at baseline, 12, 26 and 52 weeks (W). Results: Results show a net positive effect on aerobic fitness, bodyweight and WC, with significant (p<0.05) net change scores observed in the IG compared to the CG (METS: 12W=+2.20, 26W=+1.89, 52W=+0.92; Weight: 12W=-1.72kg, 26W=-1.95kg, 52W=-1.89kg; WC: 12W=-4.54cm, 26W=-2.69cm, 52W=-3.16cm). The corresponding reduction in cardiovascular disease risk is particularly significant in the context of a previously inactive and overweight cohort. The high ‘dropout’ (42.7% presenting at 52W) however, is of particular concern, with ‘dropouts’ having lower levels of aerobic fitness and higher bodyweight/WC at baseline. Conclusions: Notwithstanding dropout issues, findings address an important gap in public health practice by informing the translational scale-up of a small controllable gender-specific PA intervention, MOM, to a national population based PA intervention targeting inactive men

    Discordant Immune Response with Antiretroviral Therapy in HIV-1: A Systematic Review of Clinical Outcomes.

    BACKGROUND A discordant immune response (DIR) is a failure to satisfactorily increase CD4 counts on ART despite successful virological control. Literature on the clinical effects of DIR has not been systematically evaluated. We aimed to summarise the risk of mortality, AIDS and serious non-AIDS events associated with DIR with a systematic review. METHODS The protocol is registered with the Centre for Review Dissemination, University of York (registration number CRD42014010821). Included studies investigated the effect of DIR on mortality, AIDS, or serious non-AIDS events in cohort studies or cohorts contained in arms of randomised controlled trials for adults aged 16 years or older. DIR was classified as a suboptimal CD4 count (as defined by the study) despite virological suppression following at least 6 months of ART. We systematically searched PubMed, Embase, and the Cochrane Library to December 2015. Risk of bias was assessed using the Cochrane tool for assessing risk of bias in cohort studies. Two authors applied inclusion criteria and one author extracted data. Risk ratios were calculated for each clinical outcome reported. RESULTS Of 20 studies that met the inclusion criteria, 14 different definitions of DIR were used. Risk ratios for mortality in patients with and without DIR ranged between 1.00 (95% CI 0.26 to 3.92) and 4.29 (95% CI 1.96 to 9.38) with the majority of studies reporting a 2 to 3 fold increase in risk. CONCLUSIONS DIR is associated with a marked increase in mortality in most studies but definitions vary widely. We propose a standardised definition to aid the development of management options for DIR

    OBJECTIVE: To assess the impact of proctoring for chronic total occlusion (CTO) percutaneous coronary intervention (PCI) in six UK centres. METHODS: We retrospectively analysed 587 CTO procedures from six UK centres and compared success rates of operators who had received proctorship with success rates of the same operators before proctorship (pre-proctored) and operators in the same institutions who had not been proctored (non-proctored). There were 232 patients in the pre-proctored/non-proctored group and 355 patients in the post-proctored group. Complexity was assessed by calculating the Japanese CTO (JCTO) score for each case. RESULTS: CTO PCI success was greater in the post-proctored compared with the pre-proctored/non-proctored group (77.5% vs 62.1%, p<0.0001). In more complex cases where JCTO≥2, the difference in success was greater (70.7% vs 49.5%, p=0.0003). After proctoring, there was an increase in CTO PCI activity in centres from 2.5% to 3.5%, p<0.0001 (as a proportion of total PCI), and the proportion of very difficult cases with JCTO score ≥3 increased from 15.3% (35/229) to 29.7% (105/354), p<0.0001. CONCLUSIONS: Proctoring resulted in an increase in procedural success for CTO PCI, an increase in complex CTO PCI and an increase in total CTO PCI activity. Proctoring may be a valuable way to improve access to CTO PCI and the likelihood of procedural success

    The double burden of malnutrition and dietary patterns in rural Central Java, Indonesia

    Get PDF
    Background: Indonesia is undergoing a nutrition transition (NT) comprised of rising rates of over- weight/obesity and consumption of high fat food/snacks but is still struck by undernutrition, causing a double burden of malnutrition. Little research pertains to the double burden of malnutrition and its associations with diet in rural Indonesia using primary village level data. Methods: We conducted a 24-hour food recall and food frequency questionnaire and assessed anthropo- metric status of rural villagers from four villages in Central Java, Indonesia. Exploratory principal compo- nent analysis was used to identify dietary patterns and multi-level modeling was performed to identify variables associated with dietary pattern indicative of the NT. Findings: 1,521 participants were included in analysis. Double burden of malnutrition was prevalent whereby 32.3% of children were stunted, 68.8% of women 35-49 years-old were overweight, and 39% of homes were classified as double burden. The NT was evident in a dietary pattern associated with soft drink, snacks, and animal products. There was small but significant correlation between undernutri- tion and stunting status among children (r = −0.139, p < 0.01). The NT was associated with young age (B = 1.696, 95% CI = 1.508-1.885) but not with overweight (B = −0.099, 95% CI = −0.184-−0.013). Interpretation: Our findings suggest that whilst the typical pattern of the double burden of malnutrition (stunted child/overweight adult) exists in rural Central Java, dietary patterns indicative of the NT are predominant among children, not adults. Overweight among adults may not be necessarily due to a diet indicative of the NT, and nutrition interventions in rural Central Java should focus on educating parents of young children about the health-risks of a diet associated with a NT.
