Psychiatric wards: places of safety?

In recent years, the purpose and quality of provision delivered in acute inpatient psychiatric settings have been increasingly questioned. Studies from a service user perspective have reported that while some psychiatric inpatients feel safe and cared for, others feel their time in hospital is neither safe nor therapeutic. This paper explores the experiences of service users on acute inpatient psychiatric wards in England, with a particular focus on their feelings of safety and security. Interviews were conducted with 60 psychiatric inpatients in England. The majority of service users felt safe in hospital and felt supported by staff and other service users. However, anything that threatened their sense of security such as aggression, bullying, theft, racism and the use of alcohol and drugs on the ward, made some respondents feel insecure and unsafe. Psychiatric wards are still perceived by many as volatile environments, where service users feel forced to devise personal security strategies in order to protect themselves and their property. It would appear that there remains much to do before research findings and policies are implemented in ways that facilitate all service users to derive the maximum benefit from their inpatient experience.

Mindfulness as a potential intervention for stimulus over-selectivity in older adults

Ageing is related to significant declines in cognitive functioning. This effect can have a serious impact on the physical and psychological health of older adults as well as their quality of life. One phenomenon linked to cognitive deficits, particularly attention, that has been demonstrated to emerge with ageing is over-selectivity. Over-selectivity occurs when behavior is controlled by a limited number of stimuli in the environment. Mindfulness is a construct that specifically targets attention and awareness of the present moment. The current study aimed to remediate over-selectivity in an elderly population by means of a focused attention/mindfulness induction. The results of this study indicated that the level of emergent over-selectivity in an elderly population was significantly reduced after a focused attention induction when compared to an unfocused attention induction. The findings are discussed in terms of the efficacy of mindfulness training in reducing over-selectivity.

Distinctive Expression of Cancer/Testis-X Antigens in a Subset of ER Negative Breast Carcinomas

Background: Cancer/testis-X antigens are a multigene family that are predominantly expressed in human germ line cells, with little or no expression in somatic adult tissues, but become aberrantly activated in various malignancies. Some such CT-X antigens represent ideal targets for cancer immunotherapy and have already been used in clinical testing. In contrast to melanomas, bladder, lung, ovarian and hepatocellular carcinomas which show higher levels of CT-X antigen expression, the reports in breast cancers have been inconclusive to date and a comprehensive gene expression and clinicopathological analysis has yet to be performed.Material and Methods: Using sequencing data as well as nine publicly available gene expression data sets, we analyzed the expression of Cancer/testis-X antigens in more than 1900 primary breast cancers. Complementary analysis was performed on three tissue microarrays comprising a total of 201 primary breast carcinomas and 53 brain metastases. Clinical information on the ER-, PR-, HER2, Ki67, p53, EGFR and basal markers was available for statistical analysis.Results: A significantly higher expression of Cancer/testis-X antigens was found in ER negative breast carcinomas over different data sets with a concordant gene expression pattern of several Cancer/testis-X antigens. Members of the MAGEA family and NY-ESO-1/CTAG1B were consistently the most prevalent. Immunohistochemical analyses confirmed a significant correlation of MAGEA family and NY-ESO-1/CTAG1B with ER negative (pValue < 0.0001), PR negative (pValue < 0.01) and Ki67 staining (pValue < 0.0001). Many of these tumors were also positive for basal markers.Discussion: Previous studies of Cancer/testis-X antigens in breast have focused on ER positive cancers, in smaller subsets and provided inconclusive results. Using comprehensive gene expression data sets and tissue microarrays, we have demonstrated a significant association of MAGEA family and NY-ESO-1/CTAG1B with ER/PR negative breast cancer. Since these cancers represent a subgroup for which less therapeutic modalities are available, we propose the use of MAGEA and NY-ESO-1/CTAG1B cancer vaccines in the adjuvant setting as an approach to restricting tumor growth and metastases. Clinical trails using MAGEA and NY-ESO-1/CTAG1B are warranted.

Dietary antioxidant intake, allergic sensitization and allergic diseases in young children

BACKGROUND

Allergic diseases have risen in prevalence over recent decades. The aetiology remains unclear but is likely to be a result of changing lifestyle and/or environment. A reduction in antioxidant intake, consequent to reduced intake of fresh fruits and vegetables, has been suggested as a possible cause.

OBJECTIVE

To investigate whether dietary antioxidant intake at age 5 was related to atopy at 5 and 8 years of age amongst children in an unselected birth cohort.

METHODS

Children were followed from birth. Parents completed a validated respiratory questionnaire and children were skin prick tested at 5 and 8 years of age. Serum IgE levels were measured at age 5. At age 5, antioxidant intake was assessed using a semi-quantitative food frequency questionnaire (FFQ). A nutrient analysis program computed nutrient intake, and frequency counts of foods high in the antioxidant vitamins A, C and E were assessed.

RESULTS

Eight hundred and sixty-one children completed both the respiratory and FFQ. Beta-carotene intake was associated with reduced risk of allergic sensitization at age 5 [0.80 (0.68-0.93)] and 8 [0.81 (0.70-0.94)]. In addition, beta-carotene intake was negatively associated with total IgE levels (P = 0.002). Vitamin E intake was associated with an increased risk of allergic sensitization [1.19 (1.02-1.39)], only at age 5. There was no association between antioxidant intakes and wheeze or eczema.

CONCLUSION

Increased beta-carotene intake was associated with a reduced risk of allergic sensitization and lower IgE levels, in 5- and 8-year-old children. Dietary antioxidants may play a role in the development of allergic sensitization.

The role of lipopolysaccharide in the development of atopy in humans

Atopy is a highly prevalent condition and remains the single biggest risk factor for asthma. Although atopy has a heritable component, the time frame of the increase in the prevalence indicates that it is not due to genetic factors alone. The relationship between allergen exposure and sensitization is complex. Lipopolysaccharide (LPS) and its bioactive moiety endotoxin are common to all gram-negative bacteria, and have been used as a surrogate of microbial load. Endotoxin can be readily measured in dust collected from homes. Some studies have demonstrated a clear inverse dose-response relationship between exposure to endotoxin and the risk of atopy but this finding has not been reproduced in all studies. Our innate immune system recognizes LPS readily via the LPS signal transduction pathway, which has the trimolecular complex of CD14/TLR4/MD2 at the core. A common single-nucleotide polymorphism in the promoter region of CD14 rs2569190 C to T (CD14/-260 or CD14/-159) has been associated with elevated sCD14. Although early studies suggested that this variant was associated with more severe atopy, this finding was not uniformly replicated. It has now been demonstrated in four independent populations that high exposure to endotoxin in the domestic environment is protective against the development of atopy, but only among carriers of the C allele, that is, the environmental exposure is only relevant when taken in the context of the genotype. Furthermore, this interaction is biologically plausible. We propose that neither the environmental exposure nor the genotype in isolation is sufficient to cause complex diseases like asthma and atopy, but disease results from the one acting in the context of the other, of which CD14 and endotoxin is one example contributing to the risk for atopy.

Manual restraint of adult psychiatric inpatients: a literature review

Relatively little is known about the prevalence of manual restraint to manage violent or challenging behaviour in hospital psychiatric services or the circumstances of its use. This review identified 45 empirical studies of manual restraint of adult psychiatric inpatients, mostly from the UK. On average, up to five episodes per month of manual restraint might be expected on an average 20-bed ward. Episodes last around 10 min, with about half involving the restraint of patients on the floor, usually in the prone position. Manually restrained patients tend to be younger, male and detained under mental health legislation. Staff value restraint-related training, but its impact on nursing practice has not been evaluated. Research has tended to focus on official reports of violent incidents rather than manual restraint per se. Larger and more complex studies are needed to examine how manual restraint is used in response to different types of incident and in different service settings.

An unusual case of Epstein-Barr virus driven lymphoproliferative disorder of the conjunctiva which mimicked a high grade lymphoma: a sheep in wolf's clothing

Lymphoid proliferations represent 25-33% of acquired sub-epithelial conjunctival lesions which are excised or biopsied in patients over 15 years of age. These lesions are reported in association with Epstein-Barr virus (EBV). One such case of EBV associated spontaneously regressed monoclonal B cell infiltrate in conjunctiva that mimicked a large B cell lymphoma is reported.

Locked doors in acute inpatient psychiatry: a literature review

Many acute inpatient psychiatric wards in the UK are permanently locked, although this is contrary to the current Mental Health Act Code of Practice. To conduct a literature review of empirical articles concerning locked doors in acute psychiatric inpatient wards, an extensive literature search was performed in SAGE Journals Online, EBM Reviews, British Nursing Index, CINAHL, EMBASE Psychiatry, International Bibliography of the Social Sciences, Ovid MEDLINE, PsycINFO and Google, using the search terms 'open$', 'close$', '$lock$', 'door', 'ward', 'hospital', 'psychiatr', 'mental health', 'inpatient' and 'asylum'. A total of 11 empirical papers were included in the review. Both staff and patients reported advantages (e.g. preventing illegal substances from entering the ward and preventing patients from absconding and harming themselves or others) and disadvantages (e.g. making patients feel depressed, confined and creating extra work for staff) regarding locked doors. Locked wards were associated with increased patient aggression, poorer satisfaction with treatment and more severe symptoms. The limited literature available showed the urgent need for research to determine the real effects of locked doors in inpatient psychiatry.

Associations of wheezing phenotypes in the first 6 years of life with atopy, lung function and airway responsiveness in mid-childhood

Background:

Patterns of wheezing during early childhood may indicate differences in aetiology and prognosis of respiratory illnesses. Improved characterisation of wheezing phenotypes could lead to the identification of environmental influences on the development of asthma and airway diseases in predisposed individuals.

Methods:

Data collected on wheezing at seven time points from birth to 7 years from 6265 children in a longitudinal birth cohort (the ALSPAC study) were analysed. Latent class analysis was used to assign phenotypes based on patterns of wheezing. Measures of atopy, airway function (forced expiratory volume in 1 s (FEV₁), mid forced expiratory flow (FEF_25-75)) and bronchial responsiveness were made at 7–9 years of age.

Results:

Six phenotypes were identified. The strongest associations with atopy and airway responsiveness were found for intermediate onset (18 months) wheezing (OR for atopy 8.36, 95% CI 5.2 to 13.4; mean difference in dose response to methacholine 1.76, 95% CI 1.41 to 2.12 %FEV₁ per μmol, compared with infrequent/never wheeze phenotype). Late onset wheezing (after 42 months) was also associated with atopy (OR 6.6, 95% CI 4.7 to 9.4) and airway responsiveness (mean difference 1.61, 95% CI 1.37 to 1.85 %FEV₁ per μmol). Transient and prolonged early wheeze were not associated with atopy but were weakly associated with increased airway responsiveness and persistent wheeze had intermediate associations with these outcomes.

Conclusions:

The wheezing phenotypes most strongly associated with atopy and airway responsiveness were characterised by onset after age 18 months. This has potential implications for the timing of environmental influences on the initiation of atopic wheezing in early childhood.

The effect of anti-Rho(D) and non-specific immunoglobulins on monocyte Fc receptor function: the role of high molecular weight IgG polymers and IgG subclasses

Anti-Rho(D) immunoglobulin (anti-D) contained more high molecular weight (HMW) IgG polymers than intravenous non-specific immunoglobulin (i.v. Ig). The low-dose anti-D and high-dose i.v. Ig regimens used to treat idiopathic thrombocytopenic purpura (ITP) therefore contained similar total amounts of HMW IgG. In vitro, the HMW IgG polymers were more effective competitive inhibitors of monocyte phagocyte Fc receptors than monomeric IgG. The IgG subclass composition of anti-D and i.v. Ig were both similar to normal human plasma. We conclude that the HMW IgG content but not the IgG subclass composition of anti-D may explain its low-dose therapeutic efficacy in ITP.

Patient ethnicity and three psychiatric intensive care units compared: the Tompkins Acute Ward Study

Psychiatric care units provide care to disturbed patients in a context of higher security and staffing levels. Although such units are numerous, few systematic comparisons have been made, and there are indications that ethnic minority groups may be over-represented. The aim of this study was to compare the rates of adverse incidents and patterns of usage of three psychiatric intensive care units. The study used a triangulation or multi-method design, bringing together data from official statistics, local audit and interviews conducted with staff. Intensive care patients were more likely to be young, male and suffering a psychotic disorder, as compared with general acute ward patients. Caribbean patients were twice as likely, and Asian patients half as likely, to receive intensive care (age, gender and diagnosis controlled). There were large differences in service levels, staffing, team functioning and adverse incidents between the three units. Various aspects of physical security were important in preventing absconds. More evaluative research is required in order to define effective service levels, and to explore the nature of the interaction between ethnicity and inpatient care provision during acute illness.

Collaborative care for depression in UK primary care: a randomized controlled trial

BACKGROUND

Collaborative care is an effective intervention for depression which includes both organizational and patient-level intervention components. The effect in the UK is unknown, as is whether cluster- or patient-randomization would be the most appropriate design for a Phase III clinical trial.

METHOD

We undertook a Phase II patient-level randomized controlled trial in primary care, nested within a cluster-randomized trial. Depressed participants were randomized to 'collaborative care' - case manager-coordinated medication support and brief psychological treatment, enhanced specialist and GP communication - or a usual care control. The primary outcome was symptoms of depression (PHQ-9).

RESULTS

We recruited 114 participants, 41 to the intervention group, 38 to the patient randomized control group and 35 to the cluster-randomized control group. For the intervention compared to the cluster control the PHQ-9 effect size was 0.63 (95% CI 0.18-1.07). There was evidence of substantial contamination between intervention and patient-randomized control participants with less difference between the intervention group and patient-randomized control group (-2.99, 95% CI -7.56 to 1.58, p=0.186) than between the intervention and cluster-randomized control group (-4.64, 95% CI -7.93 to -1.35, p=0.008). The intra-class correlation coefficient for our primary outcome was 0.06 (95% CI 0.00-0.32).

CONCLUSIONS

Collaborative care is a potentially powerful organizational intervention for improving depression treatment in UK primary care, the effect of which is probably partly mediated through the organizational aspects of the intervention. A large Phase III cluster-randomized trial is required to provide the most methodologically accurate test of these initial encouraging findings.

Quantification of atopy and the probability of rhinitis in preschool children: a population-based birth cohort study

BACKGROUND

Atopy quantification using IgE levels/skin test diameter (SPT-MWD) may better predict the expression of rhinitis than using atopy as a dichotomous variable.

OBJECTIVE

To investigate the association between the presence, temporal pattern and severity of rhinitis in preschool children and specific IgE levels/SPT-MWDs.

METHODS

Children were followed prospectively to age 5 years in a whole-population birth cohort study. We administered questionnaires (n = 815), skin prick tested children (n = 717) and measured specific serum IgE (n = 478) to inhalant and food allergens. Main outcomes were current rhinitis (CR) and current rhinoconjunctivitis (CRC).

RESULTS

The prevalence of CR and CRC was 26.1% and 12.1%, respectively. The risk of CR and CRC increased significantly with increasing IgE to grass, mite and cat; CRC was also associated with increasing IgE to dog and peanut. Similarly, increasing SPT-MWDs to inhalant allergens were significantly associated with CR and CRC. This association was also shown for grass within the group of atopic children. Perennial and seasonal rhinitis were associated with increasing IgE/SPT-MWD to mite and grass, respectively. Moderate/severe rhinitis was associated with increasing IgE/SPT-MWD to grass. In a multivariate analysis, increasing levels of IgE/SPT-MWD to grass were the strongest independent predictors of both CR (for IgE: OR 1.42, 95% CI 1.23-1.64, P < 0.001) and CRC (for IgE: 1.51, 1.30-1.76, P < 0.001).

CONCLUSION

The probability of CR/CRC increases with increasing specific IgE levels or SPT-MWD. With respect to allergic rhinitis, the absolute levels of specific IgE antibody or the size of SPT wheal offer more information than just the presence/absence of sensitization.

Mental health and debt: challenges for knowledge, practice and identity

People with mental health problems (MHPs) in Britain are nearly three times more likely to report debt compared with individuals without similar conditions. With one-in-four respondents with MHPs reporting personal debt, this may be equivalent to eight or nine clients in the recommended national community mental health nurses' (CMHNs) caseload of 35. Although client debt is not a new problem for CMHNs, it can pose significant difficulties for client well-being and nursing practice. This paper reviews the published literature on debt and mental health, then considers three of the challenges that client debt can present to: (1) nursing knowledge--moving away from understandings of client debt based on crisis, and towards those focused on process and prevention; (2) nursing practice--reworking the collaborative relationship between CMHNs and external debt advice agencies; and (3) nursing identity--managing the role conflicts that engaging with client debt can bring. The paper concludes by contending that nurses should raise and monitor debt issues among clients, but cannot be expected to become proxy 'debt advisors', with CMHNs being encouraged to increasingly collaborate with debt advisors (rather than simply referring on clients).

Rhinoconjunctivitis in 5-year-old children: a population-based birth cohort study

BACKGROUND

There is a paucity of data on the prevalence, risk factors and natural history of rhinitis in early childhood.

OBJECTIVE

Within the context of a whole-population birth cohort we investigated the prevalence of and risk factors for current rhinoconjunctivitis (CRC) at age 5 years.

METHODS

Children were followed prospectively to age 5 years [questionnaires (n = 815), skin testing (n = 717), specific immunoglobulin E (n = 478), lung function (n = 711), dry air challenge (n = 556)]. Endotoxin and allergen exposures were measured in dust samples.

RESULTS

The prevalence of rhinitis ever, current rhinitis and rhinoconjunctivitis was 28.2%, 26.1%, and 12.1%, respectively. Asthma, wheeze and eczema coexisted with CRC (P < or = 0.01). In a multivariate model, maternal asthma (OR 2.38, 95% CI: 1.30-4.38, P = 0.005), paternal hay fever (1.96, 1.11-3.46, P = 0.02) and sensitization to grass (3.46, 1.86-6.42, P < 0.001) and cat (2.42, 1.14-5.18, P = 0.02) remained significant and independent associates of CRC. Whilst almost half of children with CRC were nonatopic, there was little difference in risk factors between atopic and nonatopic CRC. Amongst children with current wheeze, the presence of concurrent CRC had no effect on either severity or frequency of wheezy episodes. There was no difference in specific airway resistance, forced expiratory volume in 1 second (FEV(1)) or airway reactivity between children with and without CRC after adjustment for the presence of wheeze.

CONCLUSION

Family history of allergic disease and sensitization to inhalant allergens are risk factors for rhinoconjunctivitis in preschool children. In this age group, there is no association between the presence of rhinoconjunctivitis and severity of wheeze, increased airway reactivity and reduced lung function.
