Despite frequent use of subjective adherence measures in patients with schizophrenia as well as other chronic conditions, there are several reports that question the validity of these instruments. Three well known, representative subjective measures are the Medication Adherence Questionnaire (MAQ), the Drug Attitude Inventory (DAI), and the Compliance Rating Scale (CRS). In this study we explored the predictive validity of these instruments in a European sample of 119 stabilized outpatients with schizophrenia. Clinical outcome variables were relapse and admission to a psychiatric hospital during a follow‐up period of 12 months. Results indicate that the predictive validity of all three measures was poor. The MAQ was the least problematic predictor for relapse (Nagelkerke R2 = 0.09), and time to relapse (R2 = 0.07) and had the best sensitivity for relapse (63.6%) as well as admission (87.5%). The MAQ and CRS were both moderate predictive for admission (Nagelkerke R2 = 0.21, and R2 = 0.29). We conclude that the validity of the instruments studied here is questionable and have limited clinical relevance. Given the feasibility and ease of most subjective instruments, researchers may be tempted to use them but should be aware of the serious drawbacks of these instruments.

BACKGROUND: Young adults, especially men, are among those least likely to consult healthcare professionals when mentally distressed or suicidal. AIMS: To investigate the help-seeking behaviours of mentally distressed young adults. Design of study: Cross-sectional survey. SETTING: Bristol and surrounding areas, including inner-city, suburban and urban locations. METHOD: A questionnaire was sent to a sample of 3004 young adults aged 16-24 years. This assessed probable mental disorder (using the 12-item general health questionnaire [GHQ-12]), suicidal thoughts (GHQ-28 suicide subscale), and help-seeking behaviours. RESULTS: Most responders who were assessed as having probable mental disorders (GHQ "cases") had not sought help. Help seeking was more common in female GHQ cases than male cases (34.8% and 21.8%,respectively; P = 0.003) and women with suicidal thoughts more commonly sought help than men with suicidal thoughts (41.6% and 30.9%, respectively; P = 0.15). Small proportions of male and female GHQ cases (7.5% and 8.9%, respectively; P = 0.6), and less than one in five responders with suicidal thoughts, had consulted a general practitioner. In more female than male cases, help was sought from family and friends (30.7% and 18.4%, respectively; P = 0.004). GHQ score was the strongest predictor of help seeking. Men had a higher threshold of severity at which they would seek help than women. Recent experience of suicidal thoughts appeared to be a stronger predictor of formal help seeking in mentally distressed women than mentally distressed men. CONCLUSION: Distressed young adults are reluctant to seek help. Men are particularly unlikely to do so unless severely distressed and tend not to seek lay support. Sex differences in help seeking may be important in understanding the high suicide rate for men.  相似文献

Background

The palliative care approach has the potential to improve care for patients with progressive life-threatening illnesses from the time of diagnosis. Policy and clinical directives in the UK advocate early identification.

Aim

To determine the extent to which practices identify patients for palliative care, including factors influencing early identification and possible effects on place of death.

Design and setting

Qualitative and quantitative data were collected from six general practices from three Scottish NHS boards and analysed.

Method

Records of patients who had died in the previous 6 months were analysed and interviews with practice staff (n = 21) and with patients currently on the practice palliative care register and bereaved relatives (n = 14) were conducted. In addition, a practice meeting was observed.

Results

In total, 29% of patients who died were recorded as being on the practice palliative care register before death. Two-thirds of patients with cancer were recorded on the register, but for those with non-malignant conditions only around 20% had any palliative care documented. This was a result of GPs not finding the current guidelines useful and being reluctant to discuss palliative care overtly with patients early in their illness. Palliative care services and documentation were geared towards patients with cancer. More district nurses than GPs saw the benefits of inclusion on the palliative care register. Only 25% of patients on the register died in hospital.

Conclusion

Most patients with advanced progressive illnesses, especially those with non-malignant disease, are not being formally identified for a palliative care approach before they die. Those identified are more likely to benefit from coordinated care and may be more likely to die at home.  相似文献

The intracellular bacterium Francisella tularensis survives in mammals, arthropods, and freshwater amoeba. It was previously established that the conventional media used for in vitro propagation of this microbe do not yield bacteria that mimic those harvested from infected mammals; whether these in vitro-cultivated bacteria resemble arthropod- or amoeba-adapted Francisella is unknown. As a foundation for our goal of identifying F. tularensis outer membrane proteins which are expressed during mammalian infection, we first sought to identify in vitro cultivation conditions that induce the bacterium's infection-derived phenotype. We compared Francisella LVS grown in brain heart infusion broth (BHI; a standard microbiological medium rarely used in Francisella research) to that grown in Mueller-Hinton broth (MHB; the most widely used F. tularensis medium, used here as a negative control) and macrophages (a natural host cell, used here as a positive control). BHI- and macrophage-grown F. tularensis cells showed similar expression of MglA-dependent and MglA-independent proteins; expression of the MglA-dependent proteins was repressed by the supraphysiological levels of free amino acids present in MHB. We observed that during macrophage infection, protein expression by intracellular bacteria differed from that by extracellular bacteria; BHI-grown bacteria mirrored the latter, while MHB-grown bacteria resembled neither. Naïve macrophages responding to BHI- and macrophage-grown bacteria produced markedly lower levels of proinflammatory mediators than those in cells exposed to MHB-grown bacteria. In contrast to MHB-grown bacteria, BHI-grown bacteria showed minimal delay during intracellular replication. Cumulatively, our findings provide compelling evidence that growth in BHI yields bacteria which recapitulate the phenotype of Francisella organisms that have emerged from macrophages.  相似文献

There is a high incidence of cervical cancer in South African women. No large studies to assess human papillomavirus virus (HPV) infection or HPV type 16 (HPV-16) exposure have occurred in the region, a requirement for policy making with regards to HPV screening and the introduction of vaccines. Control women (n = 1,003) enrolled in a case control study of hormonal contraceptives and cervical cancer were tested for 27 cervical HPV types by reverse line blot analysis. The seroprevalence of HPV-16 immunoglobulin G (IgG) and IgA antibodies was assessed by a virus-like particle-based enzyme-linked immunoassay of 908 and 904 control women, respectively, and of 474 women with cervical cancer. The cervical HPV prevalence was 26.1%. The HPV-16 IgG seroprevalence was 44.4% and the HPV-16 IgA seroprevalence was 28.7% in control women, and these levels were significantly higher (61.8% and 52.7%, respectively) for women with cervical cancer (odds ratio [OR], 2.1 and 2.8, respectively). The cervical HPV prevalence showed an association with cervical disease, and the HPV-16 IgG prevalence decreased while the HPV-16 IgA prevalence increased with increasing age (P < 0.05). The prevalence of oncogenic HPV types (including HPV-16) decreased with age, whereas nononcogenic HPV types showed limited association with age. Multivariate analysis revealed cervical HPV infection to be associated with herpes simplex virus type 2 infection (OR, 1.7) and increasing years of education (OR, 1.9). HPV-16 IgG antibodies were inversely associated with current smoking status (OR, 0.6), and the presence of HPV-16 IgA antibodies was inversely associated with the use of alcohol (OR, 2.1) and inversely associated with the use of oral contraceptives (OR, 0.6). High levels of exposure to HPV, and particularly HPV-16, were evident in this population. The apparent increase of serum HPV-16 IgA with increasing age requires further investigation.  相似文献

Objective

To improve our understanding of patient participation in health care consultations and decision-making by exploring a consultation that lies at the interface between mainstream care and complementary therapies.

Methods

Thirty-four holistic consultations were observed at centres offering complementary therapies for cancer, followed by interviews with patients and focus groups with professionals.

Results

A model of decision-making about complementary therapy use emerged from the data: ‘Advice: Assessor led decision’, ‘Confirmation: Joint decision’, ‘Access: Patient-led decision’ and ‘Informed: Patient-led decision’. Decision-making style was contingent on identifiable communication strategies in the preceding information-sharing and discussion phases of the consultation.

Conclusion

This study confirms the importance of gauging patients’ preferences for level of participation in decision-making. Models of consultations are generally based on the assumption that a greater degree of patient participation is a good thing that access to information and decision-making power is sought by all patients. Data from this study suggest that, in this context at least, this is not necessarily the case. The study also stresses the dynamic nature of the consultation, in which roles are fluid rather than fixed.

Practice implications

Insight were gained into professionals’ communication strategies and patients’ role preferences in decision-making, which may be applicable more widely.  相似文献

Identification of unknown mutations has remained laborious, expensive, and only viable for studies of selected cases. Population-based "reference ranges" of rarer sequence diversity are not available. However, the research and diagnostic interpretation of sequence variants depends on such information. Additionally, this is the only way to determine prevalence of severe, moderate, and silent mutations and is also relevant to the development of screening programs. We previously described a system, meltMADGE, suitable for mutation scanning at the population level. Here we describe its application to a population-based study of MC4R (melanocortin 4 receptor) mutations, which are associated with obesity. We developed nine assays representing MC4R and examined a population sample of 1,100 subjects. Two "paucimorphisms" were identified (c.307G>A/p.Val103Ile in 27 subjects and c.-178A>C in 22 subjects). Neither exhibited any anthropometric effects, whereas there would have been >90% power to detect a body mass index (BMI) effect of 0.5 kg/m(2) at P=0.01. Two "private" variants were also identified. c.335C>T/p.Thr112Met has been previously described and appears to be silent. A novel variant, c.260C>A/p.Ala87Asp, was observed in a subject with a BMI of 31.5 kg/m(2) (i.e., clinically obese) but not on direct assay of a further 3,525 subjects. This mutation was predicted to be deleterious and analysis using a cyclic AMP (cAMP) responsive luciferase reporter assay showed substantial loss of function of the mutant receptor. This population-based mutation scan of MC4R suggests that there is no severe MC4R mutation with high prevalence in the United Kingdom, but that obesity-causing MC4R mutation at 1 in 1,100 might represent one of the commonest autosomal dominant disorders in man.  相似文献
