Experiences of initiating rapid antiretroviral therapy among people newly diagnosed with HIV in East London: a qualitative study

OBJECTIVES

We aimed to explore the experiences of people who initiated rapid antiretroviral therapy (ART) within 7 days of HIV diagnosis, as part of routine care in London.

METHODS

Using purposive sampling, 18 in-depth, semistructured interviews were conducted between December 2020 and September 2021 with people who started rapid ART at Barts Health NHS Trust. Participants aged 22-69 years included 15 cisgender men and three cisgender women. Five identified as heterosexual and 13 as gay and bisexual and other men who have sex with men. Ethnic identities: six White Non-UK, five White UK, three Black Caribbean, two South Asian and two East Asian. Interviews explored feelings about the new HIV diagnosis, attitudes to rapid ART including barriers to and facilitators of starting. Thematic analysis of transcribed interviews was undertaken.

RESULTS

Four themes were identified: (1) being offered rapid ART is acceptable; (2) it is a way of taking control of their health; (3) the need for information and support and (4) an individualised approach to care. Reasons for starting included getting well, staying well and reducing the likelihood of passing on HIV. Facilitators included being given comprehensive information about treatment and managing potential side-effects and a supportive clinical team. Support specified included a non-judgemental attitude, approachability, reassurance, encouragement and information about peer support. Most participants expressed they could not understand why people would not begin treatment, but suggested needing more time to decide and denial of diagnosis as possible barriers.

CONCLUSIONS

To our knowledge, this is the first qualitative study exploring the experiences of people initiating rapid ART in the UK. It was deemed acceptable to an ethnically diverse, predominantly male sample of people newly diagnosed with HIV. Future research should include strategies to recruit a more gender diverse sample and those who declined or stopped rapid ART.

Evaluating HIV policy: a gender analysis of the representation of womenand men in UNAIDS HIV-prevention guidelines

Gender inequalities have long been recognised as one of the most significant factors influencing the dynamics of the HIV epidemic in sub-Saharan Africa (SSA). However, it remains unclear how men and women are discussed in HIV-prevention initiatives and if certain representations of men and women impact prevention guidance. This research aimed to understand how men and women are portrayed in HIV-prevention guidelines produced by UNAIDS for the SSA region, and how these influence the different types of interventions targeted at women and men. Thirty-four UNAIDS prevention documents were included in the study. The policy documents were analysed to ascertain the frequency of different interventions suggested, the extent to which they were targeted at men and women, and a textual analysis of the way that men and women were represented. Due to a lack of information regarding other gender identities, the research was aimed at cis-gender men and women only. The analysis revealed that most policy documents focused on women, that there were differences in the types of interventions targeted at men and women, with few social interventions targeted at men, and that the language used to describe men and women repeats traditional gender stereotypes and cements simplistic dualisms. The lack of social interventions targeted at men suggests that behaviour change among men is not highly prioritised in current prevention initiatives. Instead, current UNAIDS policy focuses on women as the key site for intervention and empowerment. UNAIDS should therefore provide more details and examples about how best to engage men and boys in prevention efforts, as well as to include more nuanced conceptions of gender in policy guidance.

The effects of COVID-19 lockdown measures on health and healthcare services in Uganda

Many countries across the world instituted lockdowns as a measure to prevent the spread of COVID-19. However, these lockdowns had consequences on health systems. This study explored effects of the COVID-19 lockdown measures on health and healthcare services in Uganda. The qualitative study employed focus group discussions (FGDs), household interviews, and key informant interviews (KIIs) in both an urban (Kampala district) and rural (Wakiso district) setting in central Uganda. Fourteen FGDs were conducted among community members, local leaders, community health workers, and health practitioners. Interviews were conducted among 40 households, while 31 KIIs were held among various stakeholders including policy makers, non-governmental organisations, and the private sector. Data was analysed by thematic analysis with the support of NVivo 2020 (QSR International). Findings from the study are presented under four themes: maternal and reproductive health; child health; chronic disease services; and mental health. Maternal and reproductive health services were negatively affected by the lockdown measures which resulted in reduced utilisation of antenatal, postnatal and family planning services. These effects were mainly due to travel restrictions including curfew, and fear of contracting COVID-19. The effects on child health included reduced utilisation of services which was a result of difficulties faced in accessing health facilities because of the travel restrictions. Patients with chronic conditions could not access health facilities for their routine visits particularly due to suspension of public transport. Depression, stress and anxiety were common due to social isolation from relatives and friends, loss of jobs, and fear of law enforcement personnel. There was also increased anxiety among health workers due to fear of contracting COVID-19. The COVID-19 lockdown measures negatively affected health, and reduced access to maternal, reproductive and child health services. Future interventions in pandemic response should ensure that their effects on health and access to health services are minimised.

A win-win scenario? Employers' responses to HIV in Tanzania: A qualitative study

Workplaces have been increasingly promoted as key sites for HIV interventions, with cost-benefit analyses employed to demonstrate the financial benefits to employers for implementing workplace HIV programmes. In these analyses, the potential costs of having HIV positive employees are weighed against the costs of the workplace programmes. Despite evidence that shows some firms have saved significant sums of money through these interventions, the general response from the private sector has been limited, with most positive case studies originating from high prevalence settings. This article reports findings from qualitative fieldwork conducted in Tanzania with private and public sector employers that aimed to understand how HIV was addressed in their organisations. Our findings suggest that HIV is not generally a serious issue, and hence HIV interventions are primarily ad-hoc with few formal HIV workplace programmes. We also found that in cases where compulsory testing programmes were implemented, employees did not turn up for testing and thus lost access to employment. Our findings suggest that relying on workplace programmes in lower prevalence settings is no substitute for investment in public health systems. Employer interventions should emphasise education and awareness, condom distribution and the promotion and provision of self-testing kits.

Epidemics, Lockdown Measures and Vulnerable Populations: A Mixed-Methods Systematic Review of the Evidence of Impacts on Mother and Child Health in Low-and Lower-Middle-Income Countries

BACKGROUND

The aim of this research was to synthetise the existing evidence on the impact of epidemic-related lockdown measures on women and children's health in low- and lower-middle-income countries (LLMICs).

METHODS

A mixed-methods systematic review was conducted of qualitative, quantitative and mixed-methods evidence. Between 1st and 10th of November 2021, seven scientific databases were searched. The inclusion criteria were that the paper provided evidence on the impact of lockdown and related measures, focused on LLMICs, addressed impacts on women and child's health, addressed epidemics from 2000-2020, was peer-reviewed, provided original evidence, and was published in English. The Joanne Briggs Institute's critical appraisal tools were used to assess the quality of the studies, and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for reporting. The evidence from the papers was grouped by type of lockdown measure and categories of impact, using a narrative data-based convergent synthesis design.

RESULTS

The review process identified 46 papers meeting the inclusion criteria from 17 countries that focussed on the coronavirus disease 2019 (COVID-19) and Ebola epidemics. The evidence on the decrease of utilisation of health services showed plummeting immunisation rates and faltering use of maternal and perinatal services, which was linked to a growth of premature deaths. Impacts on the mental health of children and women were convincingly established, with lockdowns associated with surges in depression, anxiety and low life satisfaction. Vulnerability may be compounded by lockdowns, as livelihoods were disrupted, and poverty levels increased.

CONCLUSION

Limitations included that searches were conducted in late-2020 as new research was being published, and that some evidence not published in English may have been excluded. Epidemic-related lockdown measures carry consequences for the health of women and children in lower-income settings. Governments will need to weigh the trade-offs of introducing such measures and consider policies to mitigate their impacts on the most vulnerable.

HIV testing attitudes and practices amongst 'wealthy men': qualitative evidence from Tanzania

Evidence from nationally representative surveys conducted in sub-Saharan Africa shows that significant proportions of men in the wealthiest quintile report never having tested for HIV. Despite high prevalence rates in this quintile, no research has been conducted on the HIV testing attitudes and practices of wealthier men. This article reports findings from qualitative research conducted with 23 wealthy men in Tanzania. Whilst wealthy men reported barriers to and enablers of HIV testing previously reported by the general population, concerns around loss of social status and community standing were amplified for members of this demographic. Furthermore, HIV stigma among members of this group remains high. However, enhanced access to HIV testing through private clinics, regular healthcare appointments, health insurance schemes and the means to travel to other countries enables wealthy men to avoid stigma. In settings such as the workplace, wealthy men were able to test in public in their roles as 'leaders' to encourage others to test. Future interventions to increase testing amongst men should target settings in which these leadership roles can be taken advantage of. HIV services also need integrating into the health system to remove the need for testing and treatment to be accessed at separate clinics.

THU0033 ALTERATIONS IN THE PHENOTYPIC LANDSCAPE AND SPECIFICITY OF CD4+ T CELLS IN CCP+ AT RISK SUBJECTS BEFORE THE ONSET OF RHEUMATOID ARTHRITIS

Background:

The “Targeting Immune Responses for Prevention of RA” (TIP-RA) collaboration studies individuals at high risk for developing rheumatoid arthritis (RA) because of serum anti-citrullinated protein antibody (ACPA) positivity in absence of arthritis at baseline, and is focused on defining how they transition from at-risk to classifiable disease. One potential mechanism is the expansion of antigen specific T cells that recognize self-antigens and acquisition of disease associated T cell phenotypes. ACPA emerge years prior to clinically apparent disease and subsequently increase in their titer and breadth of specificity. However, few studies have characterized T cells during this transition.

Objectives:

To identify features associated with progression to RA by examining the specificity and surface phenotype of CD4+ T cells in individuals from the TIP-RA cohort by HLA class II tetramer staining and multi-parameter flow cytometry.

Methods:

Tetramer staining and flow cytometry were performed on peripheral blood samples from a baseline visit from CCP3- controls (n=34), CCP3+ at-risk (n=26), CCP3+ positive individuals who transitioned in the near-term to RA (called “RA converters”, n=4), and seropositive early-RA (n=21). Our staining panel allowed us to measure the frequencies of T cells specific for citrullinated alpha-enolase, aggrecan, cartilage intermediate layer protein (CILP), fibrinogen and vimentin. We then applied both supervised phenotyping and a cluster-based computational approach to compare the phenotypic landscape and specificity of antigen specific and total CD4+ T cells in each cohort.

Results:

We observed higher overall frequencies of T cells that recognize citrullinated epitopes in CCP3+ at-risk subjects than CCP- controls (p< 0.05). Among the individual specificities, elevated frequencies prior to disease onset were most prominent for CILP specific T cells. Supervised phenotypic analysis revealed an increase in CCR4+ CD4+ T cells in CCP3+ at risk subjects (p< 0.001) and a corresponding decrease in CXCR3+ CD4+ T cells that was most pronounced in RA converters and seropositive early-RA (p< 0.05). Cluster-based phenotypic analysis defined ten distinct phenotypic states present within all subjects. Each of these ten immunotypes contained T cells that recognize citrullinated epitopes. However, the predominant immunotype varied for different antigens. During progression, the frequencies of Ag specific T cells diminished when onset was imminent, but rebounded shortly after diagnosis. Concomitantly, Ag specific T cells with memory phenotypes were diminished, but subsequently reverted to TSCM, Th1, and Th1-17 like phenotypes.

Conclusion:

Our data show that disease associated changes in the antigen specificity of CD4+ T cells are present in CCP3+ at-risk subjects. Furthermore, the number of antigen specific T cells and their phenotype are perturbed before the onset of symptoms and development of classified RA. These findings support a continuum of immunologic changes that underlie risk and drive disease, motivating new approaches for early intervention.

SAT0003 ELEVATED BASELINE AND INCREASING AUTOANTIBODY LEVELS ARE ASSOCIATED WITH INCREASED RISK FOR IMMINENT ONSET OF INFLAMMATORY ARTHRITIS IN A PROSPECTIVELY STUDIED ANTI-CITRULLINATED PROTEIN ANTIBODY POSITIVE COHORT: THE TIP-RA COLLECTIVE

Background:

The Targeting Immune Responses for Prevention of RA (TIP-RA) Collaborative prospectively studies individuals at high risk for developing RA because of serum ACPA positivity in absence of baseline inflammatory arthritis (IA).

Objectives:

The objective of the analyses presented herein is to evaluate the role of baseline and changing levels of ACPA and rheumatoid factor (RF) in relationship to incident IA/RA.

Methods:

ACPA+ subjects and ACPA- controls were identified who did not have baseline historical or examination evidence of IA. ACPA+ was defined by serum elevation of anti-CCP3 ≥20 units (Inova). Subjects were evaluated annually or sooner if they had changes in joint symptoms. Factors including RFIgM and RFIgA (Inova) were also assessed, and relationships between autoantibody levels at baseline and over time and incident IA/RA were evaluated using t-tests, with paired testing where applicable.

Results:

Baseline characteristics of ACPA+ and ACPA- subjects are in Table 1. Sixteen of the 94 (17%) ACPA+ subjects developed IA/RA a mean of 518 days from the baseline visit; 14 of these met 2010 ACR/EULAR criteria for RA at the time of detection of IA. There was a trend for ACPA+ subjects who later developed IA/RA to have higher baseline levels of anti-CCP3 compared to those who did not develop IA/RA (Table 2). In addition, those who developed IA/RA had significantly higher mean levels of RFIgM and RFIgA compared to those who did not. While not statistically significant, in longitudinal analyses in the ACPA+ subjects with incident IA/RA, anti-CCP3 levels increased from baseline to identification of IA (mean [SD] of 119 [102] to 126 [100], p=0.42). Furthermore, RFIgM levels increased from 36 [49] at baseline to 43 [51] at the time of IA (p=0.31), and RFIgA levels increased from 16 [29] to 21 [31] (p=0.10). In contrast, in ACPA+ subjects who did not develop IA/RA, anti-CCP3 levels increased only slightly over follow-up of a mean of 712 days: 75 [75] to 80 [76], p=0.70 while the levels of RFIgM and RFIgA decreased slightly during the same follow-up: for RFIgM mean [SD] levels went from 9 [22] to 8 [19], p=0.74; for RFIgA, 5 [16] to 3 [12], p=0.67.

Conclusion:

In this prospectively followed cohort of ACPA+ subjects, higher levels of RFIgM and RFIgA at baseline were significantly associated with development of IA/RA within the follow-up period. Furthermore, there was a trend for rising levels of anti-CCP3 and RFIgM and A to be associated with development of IA/RA. These finding support the use of higher and/or rising levels of autoantibodies as additional features to predict imminent onset of IA/RA in ACPA+ individuals as well as potentially to use as outcomes of success of preventive interventions. Furthermore, the trend of increasing levels of RFIgM and RFIgA over time in individuals who developed IA/RA suggests that targeting pathways of RF development may lead to preventive interventions in a subset of RA.

SAT0596 ASSOCIATIONS BETWEEN CIRCULATING LIPID MEDIATORS AND INCIDENT INFLAMMATORY ARTHRITIS IN AN ANTI-CITRULLINATED PROTEIN ANTIBODY POSITIVE POPULATION

Background:

Lipid mediators are endogenously derived from the metabolism of omega-3 and omega-6 polyunsaturated fatty acids (PUFAs) and have important roles in promoting and resolving inflammation in the body (1). Epidemiological studies have shown higher omega-3 PUFA status to be associated with a lower risk of both autoimmunity and progression to inflammatory arthritis (IA) (2,3).

Objectives:

To determine the association of lipid mediators with progression from rheumatoid arthritis (RA)-related autoimmunity to inflammatory arthritis (IA).

Methods:

We conducted a prospective cohort study using data from the Studies of the Etiologies of Rheumatoid Arthritis (SERA). SERA enrolled first-degree relatives (FDRs) of individuals with RA (FDR cohort) and individuals who screened positive for RA-related autoantibodies at health fairs (screened cohort). We followed 133 anti-CCP3.1 positive participants, of which 29 developed IA (22 classified as RA by 2010 ACR/EULAR criteria). We quantified lipid mediators from stored plasma samples via liquid chromatography tandem mass spectrometry methods validated against the collection and storage methods used in the study. A priori, we selected 5S-HETE, 15S-HETE and 17S-HDHA because they are precursors to leukotrienes, Lipoxin A4 and Resolvin D series lipid mediators, respectively. We fit Cox proportional hazard models for each lipid mediator as a time-varying covariate. For lipid mediators significantly associated with progression to IA we then examined IL-1β, IL-6, IL-8 and TNF-α (Bio-Plex Pro™ assay) as potential mediators of this relationship.

Results:

Higher plasma 5S-HETE levels were associated with an increased risk of incident IA after adjusting for age at baseline, cohort (FDR or screened), and shared epitope (SE) status (Table 1). The models examining 15S-HETE and 17S-HDHA had the same trend but did not reach statistical significance. We did not find evidence that the association between 5S-HETE and IA risk was mediated by the tested pro-inflammatory cytokines, suggesting a direct role for this lipid mediator in conversion to IA.

Conclusion:

In a prospective cohort of anti-CCP positive individuals, higher circulating levels of 5S-HETE, an important precursor to pro-inflammatory leukotrienes, was associated with subsequent IA. Our findings highlight the potential pathologic and prognostic significance of these PUFA metabolites in inflammatory processes in pre-RA populations.

OP0337 DIFFERENTIAL METHYLATION OF PERIPHERAL BLOOD ADAPTIVE IMMUNE CELLS IN INDIVIDUALS AT HIGH RISK FOR RA AND WITH EARLY RA COMPARED WITH CONTROLS IDENTIFIES PATHWAYS IMPORTANT IN TRANSITION TO ARTHRITIS

Background:

The “Targeting Immune Responses for Prevention of RA” (TIP-RA) collaboration studies individuals at high risk for developing RA because of serum anti-citrullinated protein antibody positivity in absence of arthritis, and is focused on defining how they transition from at-risk to classifiable disease. One potential mechanism is through alterations in epigenetics patterns in adaptive immune cells.

Objectives:

Previous studies showed that DNA methylation patterns of early RA (ERA) synoviocytes differ from long-standing RA, suggesting that abnormal methylation occurs early in synovium and evolves over time. To extend these observations, we performed a cross-sectional analysis in TIP-RA of DNA methylation signatures in peripheral blood cells in ERA, at-risk anti-CCP3+ individuals and demographically matched CCP- controls.

Methods:

Genomic DNA was isolated from two independent cohorts of CCP- (cohorts 1 and 2, respectively: B cell: n = 17/34; memory T cell: n = 21/34; and naïve T cell: n = 21/33), CCP3+ (B cell: n = 18/37; memory T cell: n = 20/36; and naïve T cell: n = 20/35), and CCP3+ ERA (B cell: n = 4/18; memory T cell: n = 5/18; and naïve T cell: n = 5/18) after separating PBMCs using antibodies and magnetic beads. Methylation was measured by Illumina Infinium MethylationEPIC chip. Differentially methylated loci (DMLs) were identified using Welch’s t-test and mapped to gene promoter regions to define DM genes (DMGs). Principal component analysis (PCA) was used to represent relationship among groups. Pathway analysis was applied by Reactome.

Results:

For the initial cohort, 1494, 1097 and 1330 DMLs were identified among CCP+, CCP- and ERA in B cells, memory T cells and naïve T cells, respectively. For the confirmatory cohort, 523, 793 and 548 DMLs were found in corresponding cell populations. The DML overlap between the 2 cohorts was highly significant (p= 2.48E-77). The DMLs were combined for both groups and corresponded to 411, 412, and 351 DMGs in B cells, memory T cells and naïve T cells. Of these, we found 246, 198 and 195 DMGs between CCP3+ and ERA in each peripheral blood cell population, respectively. PCA showed separation of CCP+, CCP- and ERA in each of the three blood cell types by DMLs (Fig. 1). DMGs were mapped to biological pathways to identify DM pathways. Although most were not significant, there were several highly significant differences comparing CCP+, ERA and CCP- in memory T cells involving pathways, including “Interferon gamma signaling” (FDR 7.48E-14), “PD-1 signaling” (FDR 8.71E-10), “Translocation of ZAP-70 to Immunological synapse” (FDR 4.75E-10), and “Phosphorylation of CD3 and TCR zeta chains” (FDR 8.71E-10).

Figure 1.

PCA shows the separation of CCP+, CCP- and ERA patients in memory T cells in confirmatory cohort.

Conclusion:

We identified reproducible methylation signatures of CCP-, CCP+, and ERA in peripheral blood B cells, memory T cells and naïve T cells in initial and confirmatory cohorts. The methylome of ERA also demonstrated a distinctive pattern from CCP+, indicating that progression to RA is accompanied by epigenetic remodeling, especially in T cell signaling and interferon responses. These signatures identify critical pathways in CCP positivity and classifiable RA and could provide the basis of novel interventions to prevent disease.

Cellular aging over 13 years associated with incident antinuclear antibody positivity in the Baltimore Longitudinal Study of Aging

Age-associated increases in antinuclear antibodies (ANA) in the general population are commonly noted but the mechanisms underlying this observation are unclear. This study aims to evaluate whether shorter peripheral blood mononuclear cell (PBMC) telomere length, a marker of more advanced biological age, is associated with ANA positivity prevalence and incidence in middle and older aged autoimmune disease-free individuals from the Baltimore Longitudinal Study of Aging (BLSA). Telomere length was measured by Southern Blot and categorized into tertiles. ANA was measured in a 1:80 and a 1:160 dilution of sera by immunofluorescence using HEp-2 cells (seropositive = 3 or 4). Multiple logistic regression was used to estimate the odds ratios and 95% confidence intervals of ANA positivity comparing the shorter tertiles of telomere length to the longest tertile for two cross-sectional points in time and then longitudinally to assess the association between shorter telomere length and incident ANA positivity. Cross-sectional analyses were adjusted for sex, race and BMI (N = 368 baseline, N = 370 follow-up) and longitudinal analyses were adjusted for sex, race, BMI and time between baseline and follow-up (N = 246). No statistically significant cross-sectional associations were observed at baseline or follow-up. Among those where ANA negative at baseline, individuals with shorter telomeres were more likely to be ANA positive at follow-up, an average 13 years later. Individuals with short telomeres at both time periods were more likely to be ANA positive. Findings suggest that ANA positivity in the general population may be indicative of immune dysfunction resulting from advanced cellular aging processes.

MUC5B Promoter Variant and Rheumatoid Arthritis with Interstitial Lung Disease

BACKGROUND

Given the phenotypic similarities between rheumatoid arthritis (RA)-associated interstitial lung disease (ILD) (hereafter, RA-ILD) and idiopathic pulmonary fibrosis, we hypothesized that the strongest risk factor for the development of idiopathic pulmonary fibrosis, the gain-of-function MUC5B promoter variant rs35705950, would also contribute to the risk of ILD among patients with RA.

METHODS

Using a discovery population and multiple validation populations, we tested the association of the MUC5B promoter variant rs35705950 in 620 patients with RA-ILD, 614 patients with RA without ILD, and 5448 unaffected controls.

RESULTS

Analysis of the discovery population revealed an association of the minor allele of the MUC5B promoter variant with RA-ILD when patients with RA-ILD were compared with unaffected controls (adjusted odds ratio, 3.8; 95% confidence interval [CI], 2.8 to 5.2; P=9.7×10^-17). The MUC5B promoter variant was also significantly overrepresented among patients with RA-ILD, as compared with unaffected controls, in an analysis of the multiethnic case series (adjusted odds ratio, 5.5; 95% CI, 4.2 to 7.3; P=4.7×10^-35) and in a combined analysis of the discovery population and the multiethnic case series (adjusted odds ratio, 4.7; 95% CI, 3.9 to 5.8; P=1.3×10^-49). In addition, the MUC5B promoter variant was associated with an increased risk of ILD among patients with RA (adjusted odds ratio in combined analysis, 3.1; 95% CI, 1.8 to 5.4; P=7.4×10^-5), particularly among those with evidence of usual interstitial pneumonia on high-resolution computed tomography (adjusted odds ratio in combined analysis, 6.1; 95% CI, 2.9 to 13.1; P=2.5×10^-6). However, no significant association with the MUC5B promoter variant was observed for the diagnosis of RA alone.

CONCLUSIONS

We found that the MUC5B promoter variant was associated with RA-ILD and more specifically associated with evidence of usual interstitial pneumonia on imaging. (Funded by Société Française de Rhumatologie and others.).

What is it like to take antipsychotic medication? A qualitative study of patients with first-episode psychosis

ACCESSIBLE SUMMARY

What is known on the subject? Antipsychotic drugs are an important part of treatment for most patients with first episode psychosis. We do not know much about what it is like to take these drugs from the patient's point of view. What this paper adds to existing knowledge? We talked to 20 young people with psychosis about their experiences of taking antipsychotic drugs. Patients relationship with medication was complex, young people found medication often to be both good and bad at the same time. We were interested in how seemingly trivial issues--colour, taste, size, name--could be very important to young people and could result in them stopping. What are the implications for practice? We think our study highlights the complicated internal struggles that people with first episode psychosis have with medication. Our study highlights how Nurses and Doctors need to try and better understand what it is like to take these drugs and work collaboratively with patients to support them to make informed choices about treatment.

BACKGROUND

Low-dose antipsychotic medication is an important part of treatment for people experiencing a first episode of psychosis. Little is known about this group of patients' experiences of taking medication.

A qualitative study of purposively sampled young people experiencing a first episode of psychosis was carried out. A mental health nurse working in the early psychosis team interviewed participants using a structured topic guide. Interviews were subjected to thematic analysis.

RESULTS

Interviews were completed with 20 young people. Thematic analysis generated six themes: (1) the drugs do work, (2) the drugs don't work (as well as I'd like), (3) side effects, (4) the indirect effects of medication, (5) rage against the machine and (6) the not trivial issues about medication.

CONCLUSION

Our overarching meta-theme was that young people's experience of taking antipsychotics was complex; medication was often considered good and bad at the same time. Our observations underpin the importance of helping patients think through the use of antipsychotic medication in supporting their personal recovery.

Environmental and gene-environment interactions and risk of rheumatoid arthritis

Multiple environmental factors including hormones, dietary factors, infections, and exposure to tobacco smoke, as well as gene-environment interactions, have been associated with increased risk for rheumatoid arthritis (RA). The growing understanding of the prolonged period before the first onset of symptoms of RA suggests that these environmental and genetic factors are likely acting to drive the development of RA-related autoimmunity long before the appearance of the first joint symptoms and clinical findings that are characteristic of RA. This article reviews these factors and interactions, especially those that have been investigated in a prospective fashion before the symptomatic onset of RA.

Antibodies to citrullinated protein antigens (ACPAs): clinical and pathophysiologic significance

Antibodies to citrullinated protein antigens (ACPAs) are highly specific for rheumatoid arthritis (RA) and are useful in the diagnosis of RA as well as the prediction of the course and outcomes of disease. Multiple methodologies exist for measuring ACPAs, including the widely available tests for anticyclic citrullinated peptide antibodies and for antibodies to mutated/modified citrullinated vimentin. These methodologies overall have similar diagnostic accuracies for RA, although there is some variability. The discovery of ACPAs and the biology of citrullination have also led to important advances in the understanding of the pathophysiology and development of RA, especially regarding the relationship between potential genetic and environmental risk factors for RA. Going forward, research into autoimmunity to citrullinated proteins may help identify the specific etiology of RA and provide approaches for the prediction of future risk of disease, and ultimately prevention of RA.

Is the use of symphysis-fundal height measurement and ultrasound examination effective in detecting small or large fetuses?

We investigated the accuracy of using symphysis pubis-fundal height measurement and ultrasonically derived estimation of fetal weight for identifying small-for-gestational-age (SGA) and large-for-gestational-age (LGA) fetuses. A retrospective cohort study was performed using computerised records of all non-diabetic women referred for an ultrasound growth scan (US) with clinically suspected SGA or LGA singleton fetuses from 35 weeks' gestation between October 2008 and March 2009 (n = 185). Birth weight data were also collected for all births over the study period (n = 3200). One-third (34%) of ultrasound estimated fetal weights were inaccurate by >10%. However, an inaccurate ultrasound estimation did not significantly increase the likelihood of spontaneous or induced onset of labour or delivery by caesarean section. Most (79%) growth scans were performed on well-grown fetuses. The majority (80%) of SGA and LGA babies in our cohort were not identified by clinicians during routine antenatal care. From 3,200 live births, there were a total of 59 infants weighing <2,500 g or >5,000 g. Of these, only 12 had been referred for an ultrasound growth scan, indicating that abdominal palpation and fundal height measurement has a 20% sensitivity in detecting SGA or LGA fetuses. Of the 12, four were detected using ultrasound, indicating a 33% detection rate. Although ultrasound has a slightly higher sensitivity, neither clinical examination using fundal height measurements nor 3rd trimester ultrasound examinations are effective at detecting SGA or LGA fetuses.

Educating healthcare professionals to act on the physical health needs of people with serious mental illness: a systematic search for evidence

Healthcare professionals in primary and secondary care should monitor the physical health of people with serious mental illness, yet in practice this does not appear to be a routine intervention. Our objective is to develop evidence-based training for healthcare professionals to enable them all to offer better physical care to this population. We performed a systematic search with the aim of evaluating the current evidence of the efficacy of education interventions. Search terms covered Severe Mental Illness, Physical Health and Education. The search yielded 147 papers, of which none were eligible for inclusion. A number of studies were excluded from this review as although there was an implicit education package provided to healthcare professionals, no information was reported on the outcomes of this education with regard to healthcare professionals' knowledge, attitudes and behaviours. The only information that these studies provided was patient-specific outcomes. It is vital that researchers start to publish details of healthcare professional education and their outcomes in physical health and serious mental illness research.

An evidence synthesis of qualitative and quantitative research on component intervention techniques, effectiveness, cost-effectiveness, equity and acceptability of different versions of health-related lifestyle advisor role in improving health

BACKGROUND

There is a need to identify and analyse the range of models developed to date for delivering health-related lifestyle advice (HRLA), or training, for effectiveness and cost-effectiveness in improving the health and well-being of individuals and communities in the UK, with particular reference to the reduction of inequalities.

OBJECTIVES

To identify the component intervention techniques of lifestyle advisors (LAs) in the UK and similar contexts, and the outcomes of HRLA interventions.

DATA SOURCES

Stakeholder views, secondary analysis of the National Survey of Health Trainer Activity, telephone survey of health trainer leads/coordinators. A search of a range of electronic databases was undertaken [including the Applied Social Sciences Index and Abstracts (ASSIA), EMBASE, NHS Economic Evaluation Database (NHS EED), MEDLINE, Psyc INFO, etc.], as well searching relevant journals and reference lists, conducted from inception to September 2008.

REVIEW METHODS

Identified studies were scanned by two reviewers and those meeting the following criteria were included: studies carrying out an evaluation of HRLA; those taking place in developed countries similar to the UK context; those looking at adult groups; interventions with the explicit aim of health improvement; interventions that involved paid or voluntary work with an individual or group of peers acting in an advisory role; advice delivered by post, online or electronically; training, support or counselling delivered to patients, communities or members of the public. After quality assessment, studies were selected for inclusion in the review. Data were abstracted from each study according to an agreed procedure and narrative, and realist and economic approaches were used to synthesise the data. Cost-effectiveness analysis of interventions was undertaken.

RESULTS

In total, 269 studies were identified but 243 were excluded. The 26 included studies addressing chronic care, mental health, breastfeeding, smoking, diet and physical activity, screening and human immunodeficiency virus (HIV) infection prevention. Overall, there was insufficient evidence to either support or refute the use of LAs to promote health and improve quality of life (QoL), and thus uncertainty about the interventions' cost-effectiveness. However, the economic analysis showed that LA interventions were cost-effective in chronic care and smoking cessation, inconclusive for breastfeeding and mental health and not cost-effective for screening uptake and diet/physical activity. LA interventions for HIV prevention were cost-effective, but not in a UK context.

LIMITATIONS

The wide variety of LA models, delivery settings and target populations prevented the reviewers from establishing firm causal relationships between intervention mode and study outcomes.

CONCLUSIONS

Evidence was variable, giving only limited support to LAs having a positive impact on health knowledge, behaviours and outcomes. Levels of acceptability appeared to be high. LAs acted as translational agents, sometimes removing barriers to prescribed behaviour or helping to create facilitative social environments. Reporting of processes of accessing or capitalising on indigenous knowledge was limited. Ambiguity was apparent with respect to the role and impact of lay and peer characteristics of the interventions. A future programme of research on HRLA could benefit from further emphasis on identification of needs, the broadening of population focus and intervention aims, the measurement of outcomes and the reviewing of evidence.

FUNDING

This study was funded by the Health Technology Assessment programme of the National Institute for Health Research.

Interventions for reducing anxiety in women undergoing colposcopy

BACKGROUND

Before cervical cancer develops the cells of the cervix become abnormal. Following an abnormal cervical smear colposcopy is performed. Colposcopy is the visualisation of the cervix using a binocular microscope. Women experience high levels of anxiety and negative emotional responses at all stages of cervical screening. High levels of anxiety before and during colposcopy can have adverse consequences, including pain and discomfort during the procedure and high loss to follow-up rates. This review evaluates interventions designed to reduce anxiety levels during colposcopic examination.

OBJECTIVES

To compare the efficacy of various interventions aimed at reducing anxiety during colposcopic examination in women.

SEARCH STRATEGY

The Cochrane Central Register of Controlled Trials (CENTRAL), (Cochrane Library, Issue 1, 2006) MEDLINE (1951-2006), EMBASE (1980-2006), CINAHL (1982-2006), Psych Lit and CancerLit, NHMRC Clinical Trials Register, UKCCCR Register of Cancer Trials, Meta-Register and Physician Data Query Protocols.

SELECTION CRITERIA

Randomised and quasi randomised controlled trials of interventions to reduce anxiety during colposcopic examination.

DATA COLLECTION AND ANALYSIS

One author searched the citations and reference lists. Studies that appeared to meet inclusion criteria were retrieved and assessed independently by the remaining three authors. The methodological quality of included studies was assessed using the Cochrane Collaboration Back Review Group's methodological quality criteria (van Tulder 2003).

MAIN RESULTS

Eleven trials were included, these trials used various interventions to reduce anxiety. These examined 1441 women's anxiety levels after different types of intervention. These included: Information leaflets - (proved not to be associated with anxiety reduction). Counselling: pre-colposcopic counselling was not associated with anxiety reduction. Information leaflets and information video and pre-colposcopy counselling was not associated with a reduction in anxiety levels. Listening to music during colposcopy: this intervention was associated with reduction in anxiety levels (p < 0.002). Video colposcopy was associated with reduction in anxiety levels, and the reduction in anxiety was significant (p < 0.0002). Information using graphs and verbal information and information video versus information only when sought: There was no significant reduction in the level of anxiety in the intervention group. Information leaflets and information video versus information leaflets only: There was a reduction in anxiety levels in the intervention group compared to the control group (p < 0.00001).

AUTHORS' CONCLUSIONS

Anxiety appears to be reduced by playing music during colposcopy, showing information videos prior to colposcopy and viewing video colposcopy during the procedure. Although information leaflets did not reduce anxiety levels, they did increase knowledge levels and so are useful in obtaining clinical consent to the colposcopic procedure.

An innovative art therapy program for cancer patients

Art therapy is a healing art intended to integrate physical, emotional, and spiritual care by facilitating creative ways for patients to respond to their cancer experience. A new art therapy program was designed to provide cancer patients with opportunities to learn about the McMichael Canadian Art Collection and to explore personal feelings about their cancer experience through combined gallery and studio components. The role of the facilitator was to assist in the interpretation of a participant's drawing in order to reveal meaning in the art. This paper presents patients' perspectives about the new art therapy program. Content analysis of participant feedback provided information about the structure, process, and outcomes of the program. Evaluation of the art therapy/museum education program demonstrated many benefits for cancer patients including support, psychological strength, and new insights about their cancer experience.

The cancer journey: bridging art therapy and museum education

This paper describes the application of art therapy in assisting cancer patients to visually express their cancer experience on several levels--physically, psychosocially, and spiritually. The art therapy/museum education program was developed in 1996 at the McMichael Canadian Art Collection in partnership with Toronto-Sunnybrook Regional Cancer Centre-Bayview Support Network. To date, the program has run for three rounds with 16 sessions in each round. The facilitator for all three rounds was a trained art therapist. The program provided an unique opportunity for an arts institution to serve the community at large by offering an artistic outlet in a peaceful, rural setting in contrast to a sterile hospital environment. The specific goals of the program and the general therapeutic benefits of art therapy are described. In addition, the effectiveness of an existential/phenomenological approach in not only serving the cancer population, but also bridging the two diverse disciplines--art therapy and museum education--is explored. It is suggested that an existential therapeutic approach promotes the confrontation and acceptance of death that is necessary in order to lead a more meaningful life. Moreover, a phenomenological approach promotes the act of "seeing" as an essential ingredient in gaining objectivity and bringing unconscious thoughts into consciousness. The importance of social and emotional support in the way of art therapy in addition to medical care is emphasized. Through art therapy, cancer patients are encouraged to discover ways to face pain and misfortune and be creative in their "art of living."
