RESUMEN

PURPOSE: The aim of this study was to identify the most appropriate measure of quality of life (QoL) for patients living with and beyond cancer. METHODS: One hundred eighty-two people attending cancer clinics in Central London at various stages post-treatment, completed a series of QoL measures: FACT-G, EORTC QLQ-C30 , IOCv2 (positive and negative subscales) and WEMWBS, a wellbeing measure. These measures were chosen as the commonest measures used in previous research. Correlation tests were used to assess the association between scales. Participants were also asked about pertinence and ease of completion. RESULTS: There was a significant positive correlation between the four domain scores of the two health-related QoL measures (.32 ≤ r ≤ .72, P < .001), and a significant large negative correlation between these and the negative IOCv2 subscale scores (- .39 ≤ r ≤ - .63, P < .001). There was a significant moderate positive correlation between positive IOCv2 subscale and WEMWBS scores (r = .35, P < .001). However, neither the FACT-G nor the EORTC showed any significant correlation with the positive IOCv2 subscale. Participants rated all measures similarly with regards to pertinence and ease of use. CONCLUSION: There was little to choose between FACT-G, EORTC, and the negative IOC scales, any of which may be used to measure QoL. However, the two IOCv2 subscales capture unique aspects of QoL compared to the other measures. The IOCv2 can be used to identify those cancer survivors who would benefit from interventions to improve their QoL and to target specific needs thereby providing more holistic and personalised care beyond cancer treatment.

RESUMEN

OBJECTIVE: Cancer has been reported to trigger symptoms of post-traumatic stress disorder (PTSD) in a substantial proportion of individuals. Despite the significant burden associated with these symptoms, there are as yet no therapeutic guidelines. This systematic review aims to evaluate the effectiveness of interventions for cancer-related post-traumatic stress in order to provide an evidence base for developing appropriate clinical practice. METHODS: Databases searched until April 2018 included Psych INFO, EMBASE, Medline, and the Cumulative Index to Nursing and Allied Health Literature (CINAHL). No restrictions to study design were applied. Participants aged 18 years or older who received their cancer diagnosis in adulthood and had symptoms of cancer-related PTSD were included. Because of significant clinical heterogeneity, a meta-analysis was not performed. RESULTS: Of 508 unique titles, eight studies met study inclusion criteria: five randomised controlled trials (RCTs), one before-and-after study, one case series, and one case study. Interventions were predominately psychological and were administered to patients with a range of cancer types. Eye movement desensitisation and reprocessing and cognitive behavioural therapy-based interventions were associated with reduced symptomatology; however, overall the methodological quality of studies had limitations. CONCLUSIONS: At present, there is only weak evidence available for the effectiveness of psychological interventions in reducing symptoms of cancer-related PTSD. The majority of interventions were administered to all cancer patients regardless of whether they showed pretreatment levels of post-traumatic stress. Future studies would be better targeted towards patients with a diagnosis of cancer and who have significant levels of cancer-related post-traumatic symptoms. Higher quality trials are also needed before treatment recommendations can be made.

RESUMEN

PURPOSE: Head and neck cancer (HNC) diagnosis and treatment are distressing and have immediate detrimental impacts on functioning and quality of life (QoL). Nevertheless, little is known about long-term psychosocial effects. The aim of this study was to determine the prevalence and correlates of clinical post-traumatic stress disorder (PTSD) and subclinical post-traumatic stress symptoms (PTSS) in HNC patients surviving more than 2 years since treatment and in their partners. METHODS: HNC survivors identified from the cancer registry of a London hospital and their partners completed measures of PTSS, depression and anxiety, fear of cancer recurrence, social support, appearance concerns and health-related QoL. Data regarding their clinical and demographic characteristics were also collected. Correlations, as well as linear and logistic regression coefficients, were calculated to estimate associations with PTSS scores. RESULTS: In this analysis of 93 HNC survivors, at a mean of 6 years (SD = 4) after treatment, 33.4% reported PTSS and 11.8% met the criteria for post-traumatic stress disorder (PTSD). Fear of cancer recurrence was independently associated with PTSS (p < .01). In subgroup analyses of patient-partner dyads, 15.4% of patients and 12.8% of partners reported PTSD, with a further 33.3% of patients and 25.7% of partners demonstrating PTSS. Patients' and partners' scores did not differ significantly (p > .05). CONCLUSIONS: This is the first examination of post-traumatic stress in survivors of HNC and shows that high levels of cancer-related PTSS exist for many years after diagnosis in both patients and their partners.

RESUMEN

BackgroundDepression and obesity are highly prevalent, and major impacts on public health frequently co-occur. Recently, we reported that having depression moderates the effect of the FTO gene, suggesting its implication in the association between depression and obesity.AimsTo confirm these findings by investigating the FTO polymorphism rs9939609 in new cohorts, and subsequently in a meta-analysis.MethodThe sample consists of 6902 individuals with depression and 6799 controls from three replication cohorts and two original discovery cohorts. Linear regression models were performed to test for association between rs9939609 and body mass index (BMI), and for the interaction between rs9939609 and depression status for an effect on BMI. Fixed and random effects meta-analyses were performed using METASOFT.ResultsIn the replication cohorts, we observed a significant interaction between FTO, BMI and depression with fixed effects meta-analysis (ß = 0.12, P = 2.7 × 10-4) and with the Han/Eskin random effects method (P = 1.4 × 10-7) but not with traditional random effects (ß = 0.1, P = 0.35). When combined with the discovery cohorts, random effects meta-analysis also supports the interaction (ß = 0.12, P = 0.027) being highly significant based on the Han/Eskin model (P = 6.9 × 10-8). On average, carriers of the risk allele who have depression have a 2.2% higher BMI for each risk allele, over and above the main effect of FTOConclusionsThis meta-analysis provides additional support for a significant interaction between FTO, depression and BMI, indicating that depression increases the effect of FTO on BMI. The findings provide a useful starting point in understanding the biological mechanism involved in the association between obesity and depression.

RESUMEN

PURPOSE: The aims of this study were to examine quality of life, using the Impact of Cancer version 2 (IOCv2), in British non-Hodgkin lymphoma (NHL) survivors and investigate differences between survivors in the UK and the USA. METHODS: NHL survivors (326 UK and 667 US) completed the 37-item IOCv2 and psychological distress, fatigue and social support questionnaires. RESULTS: The IOCv2 showed good reliability in the British sample with higher internal consistency (Cronbach alpha 0.7-0.9) and no floor and ceiling effects. UK survivors showed significantly higher negative (p < 0.001) and higher positive (p = 0.003) IOC compared to US survivors. Younger survivors (p = 0.003), those with shorter time since diagnosis (p < 0.001) and with lower levels of social support (p = 0.001), showed more negative IOC in both groups. Higher negative IOC was also significantly associated with fatigue (p < 0.001) and depressive symptoms (p < 0.001) in both countries. Higher positive IOC was associated with female gender (p < 0.001), longer time since diagnosis (p = 0.02), those diagnosed at later stage (p < 0.05) and with greater social support (p = 0.004). Whereas significantly lower positive IOC was associated with white ethnicity (p < 0.001), higher education levels (p < 0.05) and fatigue (p = 0.001). CONCLUSIONS: The IOCv2 is reliable and applicable in UK and US populations. Both negative and positive IOC scores were higher in British compared to US survivors. However, in both countries, psychosocial factors consistently showed the greatest impact on QOL irrespective of clinical characteristics. Recognition and treatment of individuals with these risk factors is a high priority for improving QOL in long-term cancer survivors, as is the development of modular interventions aimed at increasing positive IOC as well as decreasing negative impact. The IOCv2 shows great potential both as a screening and assessment measure for examining cancer-related outcomes among survivors.

RESUMEN

BACKGROUND: Obesity is strongly associated with major depressive disorder (MDD) and various other diseases. Genome-wide association studies have identified multiple risk loci robustly associated with body mass index (BMI). In this study, we aimed to investigate whether a genetic risk score (GRS) combining multiple BMI risk loci might have utility in prediction of obesity in patients with MDD. METHODS: Linear and logistic regression models were conducted to predict BMI and obesity, respectively, in three independent large case-control studies of major depression (Radiant, GSK-Munich, PsyCoLaus). The analyses were first performed in the whole sample and then separately in depressed cases and controls. An unweighted GRS was calculated by summation of the number of risk alleles. A weighted GRS was calculated as the sum of risk alleles at each locus multiplied by their effect sizes. Receiver operating characteristic (ROC) analysis was used to compare the discriminatory ability of predictors of obesity. RESULTS: In the discovery phase, a total of 2,521 participants (1,895 depressed patients and 626 controls) were included from the Radiant study. Both unweighted and weighted GRS were highly associated with BMI (P < 0.001) but explained only a modest amount of variance. Adding 'traditional' risk factors to GRS significantly improved the predictive ability with the area under the curve (AUC) in the ROC analysis, increasing from 0.58 to 0.66 (95% CI, 0.62-0.68; χ(2) = 27.68; P < 0.0001). Although there was no formal evidence of interaction between depression status and GRS, there was further improvement in AUC in the ROC analysis when depression status was added to the model (AUC = 0.71; 95% CI, 0.68-0.73; χ(2) = 28.64; P <0.0001). We further found that the GRS accounted for more variance of BMI in depressed patients than in healthy controls. Again, GRS discriminated obesity better in depressed patients compared to healthy controls. We later replicated these analyses in two independent samples (GSK-Munich and PsyCoLaus) and found similar results. CONCLUSIONS: A GRS proved to be a highly significant predictor of obesity in people with MDD but accounted for only modest amount of variance. Nevertheless, as more risk loci are identified, combining a GRS approach with information on non-genetic risk factors could become a useful strategy in identifying MDD patients at higher risk of developing obesity.

RESUMEN

Problems of sexual function and fertility in long-term survivors (≥5 years) of haematological malignancy are often neglected in clinic. Our centre carried out a questionnaire study in this population addressing patient-perceived fertility and sexual function. 718 patients responded (56% of those invited; 39% Hodgkin, 45% non-Hodgkin lymphoma, 16% acute leukaemia). Respondent women were more likely to remain childless than a normal control population. Self-reported infertility was more likely in men than women [odds ratio (OR) 1·77, P = 0·001]. Myeloablative therapy increased the likelihood of childlessness (OR 2·48, P = 0·004). Few attended fertility support services (12%). 24% of men banked sperm and 29% of these used the sample, of which 46% resulted in successful pregnancy. Fertility clinic attendance and sperm storage was more likely post-1990 (OR 4·05, P < 0·001; OR 5·05, P < 0·001 respectively). Reporting a negative impact of cancer on sexual function was more common in women than men (OR 2·20, P < 0·001), and increased with current age and age at diagnosis (by 3-4% per year, P ≤ 0·001) but decreased with longer follow-up (by 2%/year, P = 0·005). Patients on anti-depressants and those reporting cancer-related body change/appearance concerns more frequently reported a negative impact (P < 0·04 and P < 0·03 respectively). These self-reported outcomes confirm literature findings, suggest improvement over time, but highlight a need for involvement of support services.

RESUMEN

To assess the impact of cancer (IOC) on subsequent quality of life (QOL), 718 long-term haematological cancer survivors completed validated psychosocial, functional and QOL scales, including IOC. Fifteen percent reported significant psychological distress, 18% high levels of fatigue and 10% moderate to severe functional impairment. These groups of participants also showed poorer QOL. There were no significant differences in psychological distress (P = 0·76), fatigue (P = 0·23) or functional impairment (P = 0·74) across different cancer subtypes. Two separate hierarchical regression analyses examined the combined association of disease-type, psychosocial and other factors on negative and positive IOC scores respectively. Higher negative IOC scores were significantly associated (P ≤ 0·001) with medical comorbidity, psychological distress, lower social support, high fatigue levels and functional impairment. Paediatric patients (diagnosed at <17 years) had significantly higher negative IOC scores than adult patients (P = 0·001); greater years since diagnosis was significantly (P < 0·001) associated with less negative IOC. Higher positive IOC was associated with acute leukaemia (P = 0·01); lower positive IOC with paediatric patients (P < 0·001), white ethnicity (P < 0·001), higher education (P = 0·003), no partner (P = 0·01) and lower social support (P = 0·01). Screening for medical comorbidity, psychological distress and fatigue identifies those needing most support and should allow earlier interventions to address negative and positive IOC to improve the well-being of cancer survivors.

RESUMEN

BACKGROUND: Obesity has been shown to be associated with depression and it has been suggested that higher body mass index (BMI) increases the risk of depression and other common mental disorders. However, the causal relationship remains unclear and Mendelian randomisation, a form of instrumental variable analysis, has recently been employed to attempt to resolve this issue. AIMS: To investigate whether higher BMI increases the risk of major depression. METHOD: Two instrumental variable analyses were conducted to test the causal relationship between obesity and major depression in RADIANT, a large case-control study of major depression. We used a single nucleotide polymorphism (SNP) in FTO and a genetic risk score (GRS) based on 32 SNPs with well-established associations with BMI. RESULTS: Linear regression analysis, as expected, showed that individuals carrying more risk alleles of FTO or having higher score of GRS had a higher BMI. Probit regression suggested that higher BMI is associated with increased risk of major depression. However, our two instrumental variable analyses did not support a causal relationship between higher BMI and major depression (FTO genotype: coefficient -0.03, 95% CI -0.18 to 0.13, P = 0.73; GRS: coefficient -0.02, 95% CI -0.11 to 0.07, P = 0.62). CONCLUSIONS: Our instrumental variable analyses did not support a causal relationship between higher BMI and major depression. The positive associations of higher BMI with major depression in probit regression analyses might be explained by reverse causality and/or residual confounding.

RESUMEN

Epidemiological studies have recognized a genetic diathesis for suicidal behavior, which is independent of other psychiatric disorders. Genome-wide association studies (GWAS) on suicide attempt (SA) and ideation have failed to identify specific genetic variants. Here, we conduct further GWAS and for the first time, use polygenic score analysis in cohorts of patients with mood disorders, to test for common genetic variants for mood disorders and suicide phenotypes. Genome-wide studies for SA were conducted in the RADIANT and GSK-Munich recurrent depression samples and London Bipolar Affective Disorder Case-Control Study (BACCs) then meta-analysis was performed. A GWAS on suicidal ideation during antidepressant treatment had previously been conducted in the Genome Based Therapeutic Drugs for Depression (GENDEP) study. We derived polygenic scores from each sample and tested their ability to predict SA in the mood disorder cohorts or ideation status in the GENDEP study. Polygenic scores for major depressive disorder, bipolar disorder and schizophrenia from the Psychiatric Genomics Consortium were used to investigate pleiotropy between psychiatric disorders and suicide phenotypes. No significant evidence for association was detected at any SNP in GWAS or meta-analysis. Polygenic scores for major depressive disorder significantly predicted suicidal ideation in the GENDEP pharmacogenetics study and also predicted SA in a combined validation dataset. Polygenic scores for SA showed no predictive ability for suicidal ideation. Polygenic score analysis suggests pleiotropy between psychiatric disorders and suicidal ideation whereas the tendency to act on such thoughts may have a partially independent genetic diathesis.

RESUMEN

Healthcare professionals (HCPs) experienced prolonged stressful conditions during the coronavirus disease 2019 pandemic, and the global situation (particularly in the United Kingdom) meant that they continue to sustain mental stress related to the subsequent cost-of-living and healthcare budgeting crises. The psychological toll on HCPs may lead to increased staff attrition, adversely impacting the quality of patient care and work security. To help mitigate this psychological impact, the current evidence is strongly supportive of healthcare providers consistently adopting programmes fostering improvement in coping and resilience, facilitating healthy lifestyle, and allocating some resources for therapeutic strategies (e.g. cognitive behavioural therapy-based strategies and other strategies specified to trauma-related issues) which can be delivered by trained professionals. We stress that some approaches are not a one-size-fits-all strategy, and we also highlight the need to encourage treatment-seeking among those who need it. These strategies are highly relevant to healthcare employers and policymakers to support all HCPs in settings marked by prolonged periods of stress. The investment in these strategies are expected not only to reduce staff attrition in the long-term, but are likely to add to the cost-effectiveness of overall healthcare budgetary allocation.

RESUMEN

BACKGROUND: Two million people in the UK are living with or beyond cancer and a third of them report poor quality of life (QoL) due to problems such as fatigue, fear of cancer recurrence, and concerns about returning to work. We aimed to develop and evaluate an intervention based on acceptance and commitment therapy (ACT), suited to address the concerns of cancer survivors and in improving their QoL. We also recognise the importance of exercise and vocational activity on QoL and therefore will integrate options for physical activity and return to work/vocational support, thus ACT Plus (+). METHODS: We will conduct a multi-centre, pragmatic, theory driven, randomised controlled trial. We will assess whether ACT+ including usual aftercare (intervention) is more effective and cost-effective than usual aftercare alone (control). The primary outcome is QoL of participants living with or beyond cancer measured using the Functional Assessment of Cancer Therapy: General scale (FACT-G) at 52 weeks. We will recruit 344 participants identified from secondary care sites who have completed hospital-based treatment for cancer with curative intent, with low QoL (determined by the FACT-G) and randomise with an allocation ratio of 1:1 to the intervention or control. The intervention (ACT+) will be delivered by NHS Talking Therapies, specialist services, and cancer charities. The intervention consists of up to eight sessions at weekly or fortnightly intervals using different modalities of delivery to suit individual needs, i.e. face-to-face sessions, over the phone or skype. DISCUSSION: To date, there have been no robust trials reporting both clinical and cost-effectiveness of an ACT based intervention for people with low QoL after curative cancer treatment in the UK. We will provide high quality evidence of the effectiveness and cost-effectiveness of adding ACT+ to usual aftercare provided by the NHS. If shown to be effective and cost-effective then commissioners, providers and cancer charities will know how to improve QoL in cancer survivors and their families.

RESUMEN

Stressful life events are an established trigger for depression and may contribute to the heterogeneity within genome-wide association analyses. With depression cases showing an excess of exposure to stressful events compared to controls, there is difficulty in distinguishing between "true" cases and a "normal" response to a stressful environment. This potential contamination of cases, and that from genetically at risk controls that have not yet experienced environmental triggers for onset, may reduce the power of studies to detect causal variants. In the RADIANT sample of 3,690 European individuals, we used propensity score matching to pair cases and controls on exposure to stressful life events. In 805 case-control pairs matched on stressful life event, we tested the influence of 457,670 common genetic variants on the propensity to depression under comparable level of adversity with a sign test. While this analysis produced no significant findings after genome-wide correction for multiple testing, we outline a novel methodology and perspective for providing environmental context in genetic studies. We recommend contextualizing depression by incorporating environmental exposure into genome-wide analyses as a complementary approach to testing gene-environment interactions. Possible explanations for negative findings include a lack of statistical power due to small sample size and conditional effects, resulting from the low rate of adequate matching. Our findings underscore the importance of collecting information on environmental risk factors in studies of depression and other complex phenotypes, so that sufficient sample sizes are available to investigate their effect in genome-wide association analysis.

RESUMEN

OBJECTIVE: Despite calls to increase the 'cultural competence' of health care providers, racially minoritised people continue to experience a range of problems when it comes to health care, including discrimination. While relevant qualitative meta-syntheses have suggested better ways forward for health care for racialised minorities, many have lacked conceptual depth, and none have specifically investigated the relational dimensions involved in care. We set out to investigate the social and cultural influences on health care interventions, focusing on psychological approaches and/or cancer care to inform the trial of a new psychological therapy for those living with or beyond cancer. METHOD: A meta-ethnography approach was used to examine the relevant qualitative studies, following Noblit and Hare, and guided by patient involvement throughout. Papers were analysed between September 2018 and February 2023, with some interruptions caused by the Covid pandemic. The following databases were searched: Ovid MEDLINE, EBSCO CINAHL, Ovid Embase, EBSCO PsycINFO, Proquest Sociology Collection (including Applied Social Sciences Index & Abstracts (ASSIA), Sociological Abstracts and Sociology Database), EBSCO SocINDEX, Ovid AMED, and Web of Science. The systematic review protocol was registered with the International Prospective Register of Systematic Reviews (PROSPERO) (ID: CRD42018107695), and reporting follows the eMERGe Reporting Guidance for meta-ethnographies (France et al. 2019). RESULTS: Twenty-nine journal papers were included in the final review. Themes (third-order constructs) developed in the paper include the centrality of the patient-practitioner relationship; how participants give meaning to their illness in connection to others; how families (rather than individuals) may make health decisions; how links with a higher power and spiritual/religious others can play a role in coping; and the ways in which a hierarchy of help-seeking develops, frequently with the first port of call being the resources of oneself. Participants in studies had a need to avoid being 'othered' in their care, valuing practitioners that connected with them, and who were able to recognise them as whole and complex (sometimes described in relational languages like 'love'). Complex family-based health decision-making and/or the importance of relations with non-human interactants (e.g. God, spiritual beings) were frequently uncovered, not to mention the profoundly emergent nature of stigma, whereby families could be relatively safe havens for containing and dealing with health challenges. A conceptual framework of 'animated via (frequently hidden) affective relationality' emerged in the final synthesis, bringing all themes together, and drawing attention to the emergent nature of the salient issues facing minoritised patients in health care interactions. CONCLUSION: Our analysis is important because it sheds light on the hitherto buried relational forces animating and producing the specific issues facing racially minoritised patients, which study participants thought were largely overlooked, but to which professionals can readily relate (given the universal nature of human relations). Thus, training around the affective relationality of consultations could be a fruitful avenue to explore to improve care of diverse patients.

RESUMEN

BACKGROUND: Little is known about the impact of different types of stressful events (for example divorce v. bereavement) on unipolar depression compared with bipolar disorder. Inconsistencies exist concerning the association between independent events (beyond an individual's control, such as bereavement) and bipolar disorder. AIMS: To examine the role of specific, independent and dependent events in mood disorders. METHOD: Life-event information was collected from 512 people with bipolar disorder, 1448 people with unipolar depression and over 600 controls. RESULTS: Various events were associated with unipolar depression and bipolar disorder, but some event specificity was detected. For example, financial crisis was more strongly related to bipolar disorder rather than unipolar depression. Independent events were only related to unipolar depression and not bipolar disorder. CONCLUSIONS: The events that were linked to bipolar disorder and unipolar depression were similar. Independent events were not associated with bipolar episodes, suggesting that life stress may be a consequence of, rather than a trigger for, bipolar episodes.

RESUMEN

OBJECTIVES: Although there is evidence in the U.S.A. and U.K. to suggest that ethnic minority groups have an inferior experience of cancer care, few studies investigate ethnic disparities in satisfaction and care experiences among survivors. Patients' illness perceptions (lay explanations for illness) and coping styles (emotional and behavioural) are influenced by ethnicity-related cultural beliefs and expectations. Depressive illness or fears of recurrence of cancer may also lead to poorer recovery and function. This paper investigates whether ethnic influences explain different coping behaviours, care experiences and help-seeking behaviours. DESIGN: Eight participants of African or Black Caribbean origin were recruited from a London support group for a series of qualitative in-depth interviews. The interviews were recorded and transcribed, and the transcripts analysed using a framework method of qualitative data analysis. The emergent themes were tested and documented to reflect the issues of importance to patients. RESULTS: Lay explanations of causes of cancer were complex and diverse reflecting cultural influences and the impact of contact with health professionals. Generally, positive views about cancer care were found, especially at the secondary care level. Primary care attracted mixed views. In contrast to American studies, no acknowledgement of discrimination on the basis of ethnicity was reported. The need to be resilient and think positively were widely acknowledged as coping strategies. Some coped by avoiding contemplation of their condition or diagnosis. Religious beliefs and practices provided coping mechanisms for some, and a means to improve confidence and avoid distressing contemplation about their condition. Family, friends and charitable groups also provided emotional and practical support. CONCLUSIONS: Subjects were generally satisfied with their care; different coping styles included positive attitudes, minimisation of difficulties or more realistic consideration of the impact of cancer.

RESUMEN

BACKGROUND: Reducing stigma associated with mental illness is an important aim of medical education, yet evidence indicates that medical students' attitudes toward patients with mental health problems deteriorate as they progress through medical school. OBJECTIVES: Authors examined medical students' attitudes to mental illness, as compared with attitudes toward other medical illness, and the influence of the number of years spent in medical school, as well as of several key socio-demographic, ethnic, and cultural variables. METHODS: A group of 760 U.K. medical students completed a nationwide on-line survey examining their attitudes toward patients with five conditions (pneumonia, depression, psychotic symptoms, intravenous drug use, long-standing unexplained abdominal complaints), using the Medical Condition Regard Scale (MCRS). Students were also asked whether they had completed the psychiatry rotation or had personal experience of mental disorders themselves or among their friends or family members. They were also asked about their ethnic group (using U.K. national census categories), religious affiliation, and how important religion was in their lives. Independent-samples t-tests and one-way ANOVA were used to compare differences between groups on the MCRS. RESULTS: Students showed the highest regard for patients with pneumonia and lowest regard for patients with long-standing, unexplained abdominal complaints. Although attitudes toward pneumonia were more positive in fifth-year students than in first-year students, attitudes toward unexplained chronic abdominal pain were worse in fifth-year students than in first-year students. Personal experience of mental health treatment, or that among family and friends, were associated with less stigmatizing attitudes. Men showed more stigmatization than women for nearly all conditions; Chinese and South Asian students showed more stigmatizing attitudes toward delusions and hallucinations than their white British counterparts. CONCLUSIONS: Medical students in this survey showed the lowest regard for patients with unexplained abdominal pain, and these attitudes were worse in the most experienced medical students. Students' gender, culture and direct or indirect experience of mental illness influenced stigmatizing attitudes.

RESUMEN

Genome-wide studies in major depression have identified few replicated associations, potentially due to heterogeneity within the disorder. Several studies have suggested that age at onset (AAO) can distinguish sub-types of depression with specific heritable components. This paper investigates the role of AAO in the genetic susceptibility for depression using genome-wide association data on 2,746 cases and 1,594 screened controls from the RADIANT studies, with replication performed in 1,471 cases and 1,403 controls from two Munich studies. Three methods were used to analyze AAO: First a time-to-event analysis with controls censored, secondly comparing controls to case-subsets defined using AAO cut-offs, and lastly analyzing AAO as a quantitative trait. In the time-to-event analysis three SNPs reached suggestive significance (P < 5E-06), overlapping with the original case-control analysis of this study. In a case-control analysis using AAO thresholds, SNPs in 10 genomic regions showed suggestive association though again none reached genome-wide significance. Lastly, case-only analysis of AAO as a quantitative trait resulted in 5 SNPs reaching suggestive significance. Sex specific analysis was performed as a secondary analysis, yielding one SNP reaching genome-wide significance in early-onset males. No SNPs achieved significance in the replication study after correction for multiple testing. Analysis of AAO as a quantitative trait did suggest that, across all SNPs, common genetic variants explained a large proportion of the variance (51%, P = 0.04). This study provides the first focussed analysis of the genetic contribution to AAO in depression, and establishes a statistical framework that can be applied to a quantitative trait underlying any disorder.
