Cochrane Reviews of non-medication-based psychotherapeutic and other interventions for schizophrenia, psychosis, and bipolar disorder: A systematic literature review

INTERNATIONAL JOURNAL OF MENTAL HEALTH NURSING, Issue 4 2009
Xenia Tricia Jung
ABSTRACT Mental health-care professionals are striving to keep up to date with health interventions that are effective and beneficial to patients. The Cochrane Reviews make available a systematic and up-to-date review of a comprehensive range of health interventions. We identified a total of 28 interventions from a systematic search and review of the Cochrane Reviews for either schizophrenia, psychosis, schizoaffective, or bipolar disorder. These interventions have been graded into tables of: strong support that merits application, moderate support that warrants consideration of application, not supported, and data that is deemed inconclusive. The tables provide a comprehensive summary and classification of evidence-based practices. This information is presented in a way to enable nurses and other health-care professionals to analyze their own practices to improve mental health services and outcomes for patients. Of the 28 interventions identified in this review, four had strong support and five had moderate support meriting application. Limitations of this review are discussed. [source]


Latest news and product developments

PRESCRIBER, Issue 2 2008

NICE should evaluate all new medicines NICE should determine the cost effectiveness of all new medicines, the Health Select Committee has concluded in its second review of the Institute. The review, prompted by criticisms from patients, health professionals and the pharmaceutical industry, found that NICE is doing ,a vital job in difficult circumstances'. The Committee called for the costs to carers and society to be included in cost effectiveness estimates (this is currently prohibited) and for cost per QALY thresholds to be aligned with NHS affordability. NICE should publish brief appraisals at the time of a product launch , these could be used to negotiate prices. GPs responsible for unlicensed co-proxamol GPs who prescribe co-proxamol are now responsible for the consequences, the MHRA warns. The Agency agrees that the drug may be needed by ,a small group of patients who are likely to find it very difficult to change from co-proxamol or where alternatives appear not to be effective or suitable'. Following the withdrawal of product licences, stock that is currently in the supply chain may be dispensed but no new stock should be released by suppliers. The Drug Tariff price of co-proxamol has now increased from £2.79 to £20.36 per 100 tablets. Vitamin D deficiency on the increase Pregnant and breastfeeding women may need vitamin D supplements, the Department of Health has warned, and GPs are seeing increasing numbers of patients with vitamin D deficiency. Endogenous synthesis may be low in some ethnic groups and dark-skinned people, and north of Birmingham there is no light of the appropriate wavelength for the synthesis of vitamin D during the winter. The Department says free vitamin supplements are available for eligible patients through its Healthy Start Scheme (www.healthystart.nhs.uk) and may also be supplied at low cost by some PCTs. Innovation and good practice recognised Innovative practice and better outcomes for patients have been recognised through awards from the NHS Alliance and Improvement Foundation presented by the Secretary of State for Health, Rt Hon Alan Johnson, at the annual NHS Alliance conference held in Manchester. The Mountwood Surgery in Northwood, Middlesex, won the CHD QOF GP Practice Award sponsored by Schering Plough for their outstanding multidisciplinary approach to tackling CHD. In addition to having a highly organised in-house cardiology team, they have produced an interactive, patient-empowering booklet for CHD. Mountwood Surgery achieved blood pressure targets of 96.79 per cent in their CHD patients. North Tees PCT wins the CHD QOF PCO Award, also sponsored by Schering Plough, for their support and encouragement to GP practices to ,own' CHD care. They provide timely feedback of performance data using funnel plots and regular communication by the CHD LIT and Cardiac Network. Even though North Tees PCT has a high CHD prevalence, 4.2 per cent vs 3.6 per cent nationally, across the 27 practices 85 per cent of patients achieved cholesterol targets and 91 per cent reached the QOF blood pressure target. The St Benedict's Hospice Day Centre Project (for the Sunderland Teaching Primary Care Trust) won the Guy Rotherham Award for its excellent multidisciplinary team improvement of the palliative care provided. This team demonstrated a thorough understanding of the use of quality improvement methods to improve patient care, and carefully measured the individual improvements they made. Through the use of a referral ,decision tree', nonattenders were reduced by 300 per cent and average waiting times halved. The Extended Primary Care (EPC) Gynaecology Service (for the Practice Based Commissioning Consortium South Manchester Hub) was highly commended for its development of an effective and innovative service offering gynaecological treatment managed within a primary care setting, allowing patients improved access closer to home. The Salford Perinatal Mental Health Project was also highly commended for effectively challenging the high levels of maternal suicides. The awards were also supported by Prescriber, the British Cardiac Patients Association and the British Cardiac Society. Anastrozole superior to tamoxifen in long term A new analysis of the ATAC trial (Lancet Oncology 2008;9:45-53) shows that the advantages of the aromatase inhibitor anastrozole (Arimidex) over tamoxifen as adjuvant therapy for breast cancer persist for at least four years after the end of treatment. After primary treatment with surgery, chemotherapy or radiotherapy, postmenopausal women with localised invasive breast cancer were randomised to five years' treatment with anastrozole or tamoxifen. Among 5216 women who were hormone-receptor positive, anastrozole increased disease-free survival by 15 per cent after 100 months. Time to recurrence and distant recurrence were also increased, though overall survival was similar; the absolute difference in time to recurrence was greater at nine years (4.8 per cent) than at five years (2.8 per cent). Joint symptoms and fractures were more frequent with anastrozole during treatment but not thereafter. Use a steroid with a LABA , MHRA reminder The MHRA has reminded clinicians that patients treated with an inhaled long-acting beta-agonist (LABA) should also use an inhaled steroid. In the latest edition of Drug Safety Update (2008;1:No.6), the Agency reviews the implications of the SMART study (Chest 2006;129:15-26), which reported an increased risk of respiratory- and asthma-related deaths among patients using salmeterol (Serevent). This is contradicted by epidemiological data suggesting that asthma-related admissions have declined since LABAs were introduced. Randomised trials also do not support such a risk, probably because inhaled steroids are used more consistently in trial settings. The latest Update notes that product licences for carisoprodol (Carisoma) have been suspended due to concerns about the risk of abuse and psychomotor effects. It also includes a comprehensive summary of drug interactions with statins, a warning that methylene blue should not be prescribed for a patient taking a drug with serotonergic activity, and a reminder that only oral formulations of desmopressin are now licensed for primary nocturnal enuresis.

Chemical natures and distributions of metal impurities in multicrystalline silicon materials

PROGRESS IN PHOTOVOLTAICS: RESEARCH & APPLICATIONS, Issue 6 2006
T. Buonassisi
Abstract We present a comprehensive summary of our observations of metal-rich particles in multicrystalline silicon (mc-Si) solar cell materials from multiple vendors, including directionally-solidified ingot-grown, sheet, and ribbon, as well as multicrystalline float zone materials contaminated during growth. In each material, the elemental nature, chemical states, and distributions of metal-rich particles are assessed by synchrotron-based analytical x-ray microprobe techniques. Certain universal physical principles appear to govern the behavior of metals in nearly all materials: (a) Two types of metal-rich particles can be observed (metal silicide nanoprecipitates and metal-rich inclusions up to tens of microns in size, frequently oxidized), (b) spatial distributions of individual elements strongly depend on their solubility and diffusivity, and (c) strong interactions exist between metals and certain types of structural defects. Differences in the distribution and elemental nature of metal contamination between different mc-Si materials can largely be explained by variations in crystal growth parameters, structural defect types, and contamination sources.

Back-contact solar cells: a review

PROGRESS IN PHOTOVOLTAICS: RESEARCH & APPLICATIONS, Issue 2 2006
Emmanuel Van Kerschaver
Abstract Ever since the first publications by R.J. Schwartz in 1975, research into back-contact cells as an alternative to cells with a front and rear contact has remained a research topic. In the last decade, interest in back-contact cells has been growing and a gradual introduction to industrial applications is emerging. The goal of this review is to present a comprehensive summary of results obtained throughout the years. Back-contact cells are divided into three main classes: back-junction (BJ), emitter wrap-through (EWT) and metallisation wrap-through (MWT), each introduced as logical descendents from conventional solar cells. This deviation from the chronology of the developments is maintained during the discussion of technological results. In addition to progress on manufacturing these cells, aspects of cell modelling and module manufacturing are discussed and an outlook towards industrial implementation is presented.

Psychosocial interventions and quality of life in gynaecological cancer patients: a systematic review

PSYCHO-ONCOLOGY, Issue 8 2009
Jolyn Hersch
Abstract Objective: Women with gynaecological cancer are at risk of poor quality of life outcomes. Although various psychosocial interventions have been developed to address these concerns, such interventions have not yet been systematically evaluated in this population. The current review provides an up-to-date and comprehensive summary of the evidence regarding the effectiveness of psychosocial interventions in women with gynaecological cancers. Methods: Relevant studies were identified via Medline, CINAHL, and PsycINFO databases (1980 to June 2008), reference lists of articles and reviews, grey literature databases, and consultations with physicians and other experts in the field. Only controlled trials comparing a psychosocial intervention with a control group in a gynaecological cancer population, with at least one quality of life variable as a main outcome, were included in the review. Two authors independently assessed trial quality and extracted data. Results: Twenty-two studies involving 1926 participants were included. There was substantial variability in study quality and results. Evidence was mixed regarding intervention effects on social and sexual functioning, distress, depression, anxiety, attitude to medical care, self-esteem and body image. Interventions generally did not improve physical or vocational outcomes. Conclusions: There was limited evidence in support of healing touch, whereas information-based interventions seemed largely unable to provide meaningful benefits. Cognitive-behavioural interventions had some positive effects. Counselling appeared to be the most promising intervention strategy for addressing quality of life concerns for women with gynaecological cancers. Copyright © 2008 John Wiley & Sons, Ltd. [source]


Activational effects of sex hormones on cognition in men

CLINICAL ENDOCRINOLOGY, Issue 5 2009
A. Ulubaev
Summary Background, Changing world demographic patterns, such as the increasing number of older people and the growing prevalence of cognitive impairment, present serious obstacles to preserving the quality of life and productivity of individuals. The severity of dementia varies from subclinical, mild cognitive impairment to neurodegenerative diseases such as Alzheimer's. In normally ageing men, these age-related cognitive declines are accompanied by gradual but marked decreases in androgen levels and changes in other hormone profiles. While developmental effects of sex hormones on cognition in the pre- and early postnatal period have been demonstrated, their activational effects in later life are still a focus of contemporary research. Although there is a plethora of published research on the topic, results have been inconsistent with different studies reporting positive, negative or no effects of sex hormones on various aspects of mental agility. Methods, This review summarizes the evidence supporting the biological plausibility of the activational effects of sex hormones upon cognition and describes the mechanisms of their actions. It offers a comprehensive summary of the studies of the effects of sex hormones on fluid intelligence in men utilizing elements from the Cochrane Collaboration Guidelines for Reviews. The results of both observational (cross-sectional and longitudinal) and interventional studies published to date are collated in table form and further discussed in the text. Factors contributing to the difficulties in understanding the effects of sex hormones on cognition are also examined. Conclusions, Although there is convincing evidence that steroid sex hormones play an organizational role in brain development in men, the evidence for activational effects of sex hormones affecting cognition in healthy men throughout adult life remains inconsistent. To address this issue, a new multifactorial approach is proposed which takes into account the status of other elements of the sex hormones axis including receptors, enzymes and other hormones.
