    Self-monitoring of blood glucose in type-2 diabetes: what is the evidence?

    DIABETES/METABOLISM: RESEARCH AND REVIEWS, Issue 6 2007
    Grace McGeoch
    Abstract Background There is a controversy about self-monitoring of blood glucose (SMBG) in patients with type 2 diabetes who are not using insulin. Randomized trials are limited in duration, size, and validity. Methods Systematic search for randomized trials and observational studies published since 1990. For inclusion studies had to report on SMBG in type 2 diabetes managed with oral hypoglycaemic agents and/or diet alone, HbA1c or clinical outcome, have at least 50 patients and be of at least 6 months' duration. Results Three randomized trials with 1000 patients were included, though all had interventions differing in the amount of education on SMBG, and in the population studied. The two larger studies had statistically significantly lower HbA1c levels with SMBG. Thirteen observational studies had information on over 60 000 patients. Smaller studies had lower initial HbA1c and showed no association between SMBG and laboratory or clinical improvement. Larger studies tended to have higher initial HbA1c and did show an association between SMBG and laboratory or clinical improvement. Overall, improvement in glycaemic control with SMBG tended to be seen in studies with initial HbA1c above 8%. Conclusions It is likely that SMBG is beneficial in some circumstances, for example as an educational tool, for patients with type 2 diabetes not using insulin who have poor glycaemic control. More information is needed at the level of the individual patient, rather than group means, and about timing and frequency of monitoring, response to those results, what constitutes effective patient education, and long-term clinical outcomes.

    Guidelines on use of anti-IFN- , antibody measurements in multiple sclerosis: report of an EFNS Task Force on IFN- , antibodies in multiple sclerosis

    EUROPEAN JOURNAL OF NEUROLOGY, Issue 11 2005
    P. S. Sørensen
    Therapy-induced binding and neutralizing antibodies is a major problem in interferon (IFN)- , treatment of multiple sclerosis. The objective of this study was to provide guidelines outlining the methods and clinical use of the measurements of binding and neutralizing antibodies. Systematic search of the Medline database for available publications on binding and neutralizing antibodies was undertaken. Appropriate publications were reviewed by one or more of the task force members. Grading of evidence and recommendations was based on consensus by all task force members. Measurements of binding antibodies are recommended for IFN- , antibody screening before performing a neutralizing antibody (NAB) assay (Level A recommendation). Measurement of NABs should be performed in specialized laboratories with a validated cytopathic effect assay or MxA production assay using serial dilution of the test sera. The NAB titre should be calculated using the Kawade formula (Level A recommendation). Tests for the presence of NABs should be performed in all patients at 12 and 24 months of therapy (Level A recommendation). In patients who remain NAB-negative during this period measurements of NABs can be discontinued (Level B recommendation). In patient with NABs, measurements should be repeated, and therapy with IFN- , should be discontinued in patients with high titres of NABs sustained at repeated measurements with 3- to 6-month intervals (Level A recommendation).

    The Organic Brain Syndrome (OBS) scale: a systematic review

    INTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 3 2006
    Karin Björkman Björkelund
    Abstract Background/Objective The Organic Brain Syndrome (OBS) Scale was developed to determine elderly patients' disturbances of awareness and orientation as to time, place and own identity, and assessment of various emotional and behavioural symptoms appearing in delirium, dementia and other organic mental diseases. The aim of the study was to examine the OBS Scale, using the eight criteria and guidelines formulated by the Scientific Advisory Committee of the Medical Outcomes Trust (SAC), and to investigate its relevance and suitability for use in various clinical settings. Method Systematic search and analysis of papers (30) on the OBS Scale were carried out using the criteria suggested by the SAC. Results The OBS Scale in many aspects satisfies the requirements suggested by the SAC: conceptual and measurement model, reliability, validity, responsiveness, interpretability, respondent and administrative burden, alternative forms of administration, and cultural and language adaptations, but there is a need for additional evaluation, especially with regard to different forms of reliability, and the translation and adaptation to other languages. Conclusions The OBS Scale is a sensitive scale which is clinically useful for the description and long-term follow-up of patients showing symptoms of acute confusional state and dementia. Although the OBS Scale has been used in several clinical studies there is need for further evaluation. Copyright © 2006 John Wiley & Sons, Ltd. [source]


    A systematic review on communicating with patients about evidence

    JOURNAL OF EVALUATION IN CLINICAL PRACTICE, Issue 1 2006
    Lyndal J Trevena MBBS (Hons) MPhilPH
    Abstract Objective, To conduct a systematic search for (1) the effectiveness of evidence-based communication tools to increase patient understanding of evidence, (2) effective formats for representing probabilistic information and (3) effective strategies for eliciting patient preferences about evidence. A case scenario is used to illustrate some of the difficulties of putting these results into practice., ,Data sources, Systematic search of The Cochrane Library, Medline, Psychinfo, Embase and Cancerlit. Review methods, Systematic reviews of randomized controlled trials (RCTs) and high quality RCTs were included. Studies were excluded if they did not address the question, were focused on behavioural outcomes without attempting to increase understanding, were concerned with counselling as a therapeutic intervention, or were specific to communication regarding clinical trial participation., ,Results, We found 10 systematic reviews of RCTs and 30 additional RCTs addressing our questions. Communication tools in most formats (verbal, written, video, provider-delivered, computer-based) will increase patients' understanding but are more likely to do so if structured, tailored and/or interactive. Probabilistic information is best represented as event rates (natural frequencies) in relevant groups of people, rather than words, probabilities or summarized as effect measures such as relative risk reduction. Illustrations such as cartoons, or graphs (vertical bar charts) appear to aid understanding. Values clarification exercises may be better than standard utility techniques for eliciting preferences in individual decision making. Looking for effective evidence-based communication tools for prostatic specific antigen testing highlighted the challenges for clinicians and consumers in accessing tools that are evidence-based in design as well as content. Conclusion, There is an increasing body of evidence supporting the design of effective evidence-based communication tools but variable access to such tools in practice. [source]


    Systematic search for mutations in the human tissue inhibitor of metalloproteinases-3 (TIMP-3) gene on chromosome 22 and association study with schizophrenia

    AMERICAN JOURNAL OF MEDICAL GENETICS, Issue 3 2001
    Chao-Chun Hung
    Abstract Several linkage studies have suggested that chromosome 22q12,q13 is a putative region for schizophrenic genes. In this study, the human tissue inhibitor of metalloproteinase-3 (TIMP-3) gene was investigated as positional candidate gene for schizophrenia because of its regulatory function on extracellular matrix proteins, cell adhesion molecules, and neural cell adhesion molecules in the brain. We systematically searched for the nucleotide variants by sequencing all the exons and their flanking intronic sequences in a sample of Chinese schizophrenic patients from Taiwan. Two silent mutations in the exon 3 were identified: c.249T,C at codon 83 (His) and c.261C,T at codon 87 (Ser). However, no mutations causing amino acid alteration or aberrant splicing of transcripts were observed. Hence, it is unlikely that the TIMP-3 gene itself may play an important role in the genetic susceptibility to schizophrenia. Further case control association study revealed a significant difference of genotype distribution of the c.249T,C between schizophrenic patients and control. This finding supports that 22q12 is a schizophrenia susceptible region, and it is likely that there might be other genetic mutations in the neighborhood of the TIMP-3 gene locus that may contribute to the susceptibility of schizophrenia. © 2001 Wiley-Liss, Inc.

    The influence of cognitive impairment on health-related quality of life in neurological disease

    ACTA NEUROPSYCHIATRICA, Issue 1 2010

    Mitchell AJ, Kemp S, Benito-León J, Reuber M. The influence of cognitive impairment on health-related quality of life in neurological disease. Background: Cognitive impairment is the most consistent neurological complication of acquired and degenerative brain disorders. Historically, most focus was on dementia but now has been broadened to include the important construct of mild cognitive impairment. Methods: Systematic search and review of articles linked quality of life (QoL) and cognitive complications of neurological disorders. We excluded QoL in dementia. Results: Our search identified 249 publications. Most research examined patients with brain tumours, stroke, epilepsy, head injury, Huntington's disease, motor neuron disease, multiple sclerosis and Parkinson's disease. Results suggested that the majority of patients with epilepsy, motor neuron disease, multiple sclerosis, Parkinson's disease, stroke and head injury have subtle cognitive deficits early in their disease course. These cognitive complaints are often overlooked by clinicians. In many cases, the cognitive impairment is progressive but it can also be relapsing-remitting and in some cases reversible. Despite the importance of severe cognitive impairment in the form of dementia, there is now increasing recognition of a broad spectrum of impairment, including those with subclinical or mild cognitive impairment. Even mild cognitive difficulties can have functional and psychiatric consequences,especially when they are persistent and untreated. Specific cognitive deficits such an inattention, dysexecutive function and processing speed may affect a number of quality of life (QoL) domains. For example, cognitive impairment influences return to work, interpersonal relationships and leisure activities. In addition, fear of future cognitive decline may also impact upon QoL. Conclusions: We recommend further development of simple tools to screen for cognitive impairments in each neurological condition. We also recommend that a thorough cognitive assessment should be a part of routine clinical practice in those caring for individuals with neurological disorders. [source]


    Patient-assessed health outcome measures for diabetes: a structured review

    DIABETIC MEDICINE, Issue 1 2002
    A. M. Garratt
    Abstract Aims To identify available disease-specific measures of health-related quality of life (HRQL) for diabetes and to review evidence for the reliability, validity and responsiveness of instruments. Methods Systematic searches were used to identify instruments. Instruments were assessed against predefined inclusion and exclusion criteria. Letters were sent to authors requesting details of further instrument evaluation. Information relating to instrument content, patients, reliability, validity and responsiveness to change was extracted from published papers. Results The search produced 252 references. Nine instruments met the inclusion criteria: Appraisal of Diabetes Scale (ADS), Audit of Diabetes-Dependent Quality of Life (ADDQoL), Diabetes Health Profile (DHP-1, DHP-18), Diabetes Impact Measurement Scales (DIMS), Diabetes Quality of Life Measure (DQOL), Diabetes-Specific Quality of Life Scale (DSQOLS), Questionnaire on Stress in Diabetic Patients-Revised (QSD-R), Diabetes-39 (D-39) and Well-being Enquiry for Diabetics (WED). The shortest instrument (ADS) has seven items and the longest (WED) has 50 items. The ADS and ADDQoL are single-index measures. The seven multidimensional instruments have dimensions covering psychological well-being and social functioning but vary in the remainder of their content. The DHP-1 and DSQOLS are specific to Type 1 diabetes patients. The DHP-18 is specific to Type 2 diabetes patients. The DIMS and DQOL have weaker evidence for reliability and internal construct validity. Patients contributed to the content of the ADDQoL, DHP-1/18, DQOL, DSQOLS, D-39, QSD-R and WED. The authors of the ADDQoL, DHP-1/18, DQOL, DSQOLS gave explicit consideration to content validity. The construct validity of instruments was assessed through comparisons with instruments measuring related constructs and clinical and sociodemographic variables. None of the instruments has been formally assessed for responsiveness to changes in health. Conclusions Five of the diabetes-specific instruments have good evidence for reliability and internal and external construct validity: the ADDQoL, DHP-1/18, DSQOLS, D-39 and QSD-R. Instrument content should be assessed for relevance before application. The instruments should be evaluated concurrently for validity and responsiveness to important changes in health. [source]


    Evidence for the effectiveness of sterile injecting equipment provision in preventing hepatitis C and human immunodeficiency virus transmission among injecting drug users: a review of reviews

    ADDICTION, Issue 5 2010
    Norah Palmateer
    ABSTRACT Aims To review the evidence on the effectiveness of harm reduction interventions involving the provision of sterile injecting equipment in the prevention of hepatitis C virus (HCV) and human immunodeficiency virus (HIV) transmission among injecting drug users (IDUs). The interventions assessed were needle and syringe programmes (NSP), alternative modes of needle/syringe provision (pharmacies, vending machines and outreach) and the provision of injecting equipment other than needles/syringes. Methods Systematic searches of the English language literature to March 2007 were undertaken to identify systematic, narrative or meta-analytical reviews (also known as a review of reviews) of the impact of interventions on HCV transmission, HIV transmission or injecting risk behaviour (IRB). Critical appraisal criteria classified the reviews as either high quality (,core') or supplementary: a framework based on the quality of reviews, the reviewers' conclusions and the designs/findings of the primary studies was used to derive evidence statements. Results Three core and two supplementary reviews of injecting equipment interventions were identified. According to the proposed framework, this study found (a) insufficient evidence to conclude that any of the interventions are effective in preventing HCV transmission; (b) tentative evidence to support the effectiveness of NSP in preventing HIV transmission; (c) sufficient evidence to support the effectiveness of NSP (and tentative evidence of an additional impact of pharmacy NSP) in reducing self-reported IRB; and (d) little to no evidence on vending machines, outreach or providing other injecting equipment in relation to any of the outcomes. Conclusions The evidence is weaker than given credit for in the literature. The lack of evidence for effectiveness of NSP vis-à-vis biological outcomes (HCV and HIV incidence/prevalence) reflects the limitations of studies that have been undertaken to investigate these associations. Particularly for HCV, low levels of IRB may be insufficient to reduce high levels of transmission. New studies are required to identify the intervention coverage necessary to achieve sustained changes in blood-borne virus transmission. [source]


    A multidimensional conceptual framework for analysing public involvement in health services research

    HEALTH EXPECTATIONS, Issue 1 2008
    Sandy R. Oliver BA PhD
    Abstract Objective To describe the development of a multidimensional conceptual framework capable of drawing out the implications for policy and practice of what is known about public involvement in research agenda setting. Background Public involvement in research is growing in western and developing countries. There is a need to learn from collective experience and a diverse literature of research, policy documents and reflective reports. Methods Systematic searches of research literature, policy and lay networks identified reports of public involvement in research agenda setting. Framework analysis, previously described for primary research, was used to develop the framework, which was then applied to reports of public involvement in order to analyse and compare these. Findings The conceptual framework takes into account the people involved; the people initiating the involvement; the degree of public involvement; the forum for exchange; and methods used for decision making. It also considers context (in terms of the research focus and the historical, geographical or institutional setting), and theoretical basis. Conclusions The framework facilitates learning across diverse experiences, whether reported in policy documents, reflections or formal research, to generate a policy- and practice-relevant overview. A further advantage is that it identifies gaps in the literature which need to be filled in order to inform future research about public involvement. [source]


    A review of the impact and effectiveness of nurse-led care in dermatology

    JOURNAL OF CLINICAL NURSING, Issue 1 2007
    Cert Ed, Molly Courtenay BSc
    Aims and objectives., To identify systematically, summarize and critically appraise the current evidence regarding the impact and effectiveness of nurse-led care in dermatology. Background., A diverse range of nurse-led models of care exist in dermatology. Primary studies have been conducted evaluating these models, but review and synthesis of the findings from these studies have not been undertaken. Method., Systematic searches of CINAHL, MEDLINE, British Nursing Index (BNI) and the RCN Library Catalogue from 1990 until March 2005. The searches were supplemented by an extensive hand search of the literature through references identified from retrieved articles and by contact with experts in the field. Results., Fourteen relevant publications were identified and included findings from both primary and secondary care. The evidence indicates that nurses are treating a number of dermatological conditions, primarily using treatment protocols, across a broad range of clinical settings. However, some nurses working in primary care, lack confidence to treat some of these conditions and the educational needs of these nurses are frequently unmet. A reduction in the severity of the condition and more effective use of topical therapies are benefits of nurse interventions on service delivery. Faster access to treatment, a reduction in referrals to the general practitioner or dermatologist and an increase in knowledge of their condition are benefits reported by patients. Conclusions., Findings of the review are generally positive. However, there are methodological weaknesses and under researched issues, e.g. cost effectiveness of nurse-led care and the prescription of medicines by nurses for patients with dermatological conditions that point to the need for further rigorous evaluation. Relevance to clinical practice., Nurse-led care is an integral element of the dermatology service offered to patients. This review highlights the impact of this care and the issues that require consideration by those responsible for the development of nurse-led models of care in dermatology. [source]


    Impact of yellow fever outbreaks on two howler monkey species (Alouatta guariba clamitans and A. caraya) in Misiones, Argentina

    AMERICAN JOURNAL OF PRIMATOLOGY, Issue 6 2010
    Ingrid Holzmann
    Abstract Two yellow fever outbreaks (YFOs) ocurred in northeastern Argentina between November 2007 and October 2008, seriously affecting populations of two howler monkey species: the brown howler Alouatta guariba clamitans and the black howler Alouatta caraya. Both howlers live syntopically in El Piñalito Provincial Park, Misiones, where four groups (36 individuals) were studied since January 2005. The first dead howlers were found on January 20, 2008, in El Piñalito. Systematic searches found 14 dead howlers within the area (12 from the study groups and two from neighboring groups), with only two young seen on January 25, 2008, and none found since up to December 2008. In October 2008, another YFO hit howler monkey populations from El Soberbio, Misiones. Overall, 59 howlers were found dead in Misiones from November 2007 to December 2008. Thanks to the alert of the howler's death in El Piñalito, a prompt human vaccination campaign started in the area. Wild howler monkey populations from both species are in a delicate situation in Misiones, especially the brown howler, an already endangered species in Argentina and endemic to the Atlantic Forest. If we add the recurrence of YFOs to the reduction of suitable habitat to small fragments, it could be only a matter of time until howler populations disappear from the Upper Paraná Atlantic Forest in Misiones.

    Efficacy of enamel matrix derivatives (Emdogain®) in treatment of replanted teeth , a systematic review based on animal studies

    DENTAL TRAUMATOLOGY, Issue 5 2008
    Annette Wiegand
    A review of the published literature [search term: (Emdogain OR enamel matrix derivative OR enamel matrix protein] AND [avulsion OR replantation OR autotransplantation)] was conducted by two independent investigators according to defined selection criteria. For data extraction of the identified animal studies, the following histomorphometric findings were considered: (i) healed PDL, (ii) surface resorption, (iii) inflammatory resorption and (iv) replacement resorption. The heterogenity of data collection and the small amount of identified publications did not allow for statistical analysis. Four controlled trials (CT) conducted in animals, but no randomized controlled trials (RCT) or clinical controlled trials (CCT) could be received from the systematic search. From the selected studies, two CT gave evidence of EMD treatment to be effective in inducing healing of replanted teeth, while one CT found no differences between EMD treated teeth and controls. Finally, one CT compared EMD and sodium fluoride application, but revealed no differences between the treatments. The data of controlled trials available are limited and conflicting. No firm conclusion regarding the efficacy of EMD application on healing of replanted or autotransplanted permanent teeth can be drawn because of lack of RCT and CCT. [source]


    Review: A systematic review of prospective studies on attention problems and academic achievement

    ACTA PSYCHIATRICA SCANDINAVICA, Issue 4 2010
    T. J. C. Polderman
    Polderman TJC, Boomsma DI, Bartels M, Verhulst FC, Huizink AC. A systematic review of prospective studies on attention problems and academic achievement. Objective:, Our aim was to provide an overview of prospective studies that have addressed the association between attention problems (AP, i.e. symptoms of hyperactivity and inattentiveness) and academic achievement (AA). Method:, We conducted a systematic search in the literature. Normal population studies and clinical studies were included. The methodological quality of each study was evaluated by objective criteria. A best evidence synthesis was used to determine the strengths of the association. Results:, Sixteen studies were included. We found convincing evidence for a negative association between AP and AA. After controlling for intelligence, comorbidity, and socioeconomic status (SES), the association between the hyperactive symptoms of AP and AA was non-significant in two studies. Conclusion:, Children with AP are at risk for lower AA and subsequent adverse outcomes later in life. Interventions in affected children should focus on their behavioural and educational development.

    The effectiveness of psychological treatments for treatment-resistant depression: a systematic review

    ACTA PSYCHIATRICA SCANDINAVICA, Issue 5 2005
    S. McPherson
    Objective:, A systematic review of all studies (controlled and uncontrolled) to evaluate psychological interventions with treatment-resistant depression. Method:, A systematic search to identify studies evaluating a psychological intervention with adults with a diagnosis of major depressive disorder who had not responded to at least one course of antidepressant medication. Results:, Twelve studies met inclusion criteria, of which four were controlled and eight uncontrolled. Treatment effect sizes were computable for four studies and ranged from 1.23 to 3.10 with a number of better quality studies demonstrating some improvements in patients following a psychological intervention. Conclusion:, Psychological treatments for depression are commonly delivered and often recommended following the failure of medication. The paucity of evidence for their effectiveness in these situations is a significant problem. There is a need for studies with a strong controlled design investigating the effectiveness of psychological treatments for patients with treatment-resistant depression. [source]


    The role of IGF-I and its binding proteins in the development of type 2 diabetes and cardiovascular disease

    DIABETES OBESITY & METABOLISM, Issue 3 2008
    Vivienne A. Ezzat
    Patients with insulin resistance and type 2 diabetes have an excessive risk of cardiovascular disease (CVD); this increased risk is not fully explained by traditional risk factors such as hypertension and dyslipidaemias. There is now compelling evidence to suggest that abnormalities of insulin-like growth factor-I (IGF-I) and one of its binding proteins, insulin-like growth factor-binding protein-1 (IGFBP-1), occur in insulin-resistant states and may be significant factors in the pathophysiology of CVD. We reviewed articles and relevant bibliographies following a systematic search of MEDLINE for English language articles between 1966 and the present, using an initial search strategy combining the MeSH terms: IGF, diabetes and CVD. Our aim was first to review the role of IGF-I in vascular homeostasis and to explore the mechanisms by which it may exert its effects. We also present an overview of the physiology of the IGF-binding proteins, and finally, we sought to summarize the evidence to date describing the changes in the insulin/IGF-I/IGFBP-1 axis that occur in type 2 diabetes and CVD; in particular, we have focused on the potential vasculoprotective effects of both IGF-I and IGFBP-1. We conclude that this system represents an interesting and novel therapeutic target in the prevention of CVD in type 2 diabetes. [source]


    Are clinical practical guidelines (CPGs) useful for health services and health workforce planning?

    DIABETIC MEDICINE, Issue 5 2010
    A critique of diabetes CPGs
    Diabet. Med. 27, 570,577 (2010) Abstract Aims, Chronic disease management is increasingly informed by clinical practice guidelines (CPGs). However, their implementation requires not only knowledge of guideline content by clinicians and practice processes that support implementation, but also a health workforce with the capacity to deliver care consistent with CPGs. This has a health services planning as well as a health workforce dimension. However, it is not known whether CPGs are described in a way that can inform health services and health workforce planning and potentially drive better quality care. This study aimed to ascertain whether CPGs are useful for health service and health workforce planning. Methods, This question was explored taking diabetes mellitus as a case study. A systematic search of Medline, EMBASE, CINAHL and Scopus was carried out to identify all CPGs relating to the management of diabetes mellitus in the primary healthcare setting. The search was limited to guidelines published in the English language between 2003 and 2009. The quality of guidelines was assessed against a subset of criteria set by the Appraisal of Guidelines for Research and Evaluation (AGREE) collaboration. Results, Seventy-five diabetes-related CPGs were identified, of which 27 met the inclusion criteria. In terms of quality, many guidelines adopted evidence-based recommendations for diabetes care (59%) and most were endorsed by national authorities (70%). With regards to coverage of 17 identified subpopulations, guidelines were generally selective in the populations they covered. Whilst many provided adequate coverage of common complications and comorbidities, approaches to management for those with reduced capacity for effective diabetes self-care were largely absent, except for indigenous populations. Conclusions, Clinical practice guidelines are potentially useful for health services and health workforce planning, but would be more valuable for this purpose if they contained more detail about care protocols and specific skills and competencies, especially for subpopulations who would be expected to have reduced capacity for effective self-care. If service planning ignores these subgroups that tend to require more resource-intensive management, underprovision of services is likely. [source]


    Review of validation studies of the Edinburgh Postnatal Depression Scale

    ACTA PSYCHIATRICA SCANDINAVICA, Issue 4 2001
    Malin Eberhard-Gran
    Objective: ,To review validation studies of the Edinburgh Postnatal Depression Scale (EPDS). Method: ,A systematic search was performed in Medline and the Science Citation Index Expanded (ISI) from the period 1987,2000. For sensitivity and specificity of the EPDS presented in each study, 95% confidence intervals were estimated. Positive and negative predictive values were estimated assuming prevalences of postpartum depression ranging from 5% to 20%. Results: ,Eighteen validation studies were identified. The study design varied between studies. The sensitivity and specificity estimates also varied: 65,100% and 49,100%, respectively. The confidence intervals were estimated to be wide. Our estimates suggest a lower positive predictive value in a normal population than in the validation study samples. Conclusion: ,Most studies show a high sensitivity of the EPDS. Because of the differences in study design and large confidence intervals, uncertainty remains regarding the comparability between the sensitivity and specificity estimates of the different EPDS versions.

    Sex differences in schizophrenia, a review of the literature

    ACTA PSYCHIATRICA SCANDINAVICA, Issue 401 2000
    Dr. Alice Leung M.D.
    Objective: To comprehensively and critically review the literature on gender differences in schizophrenia. Method: An initial search of MEDLINE abstracts (1966,1999) was conducted using the terms sex or gender and schizophrenia, followed by systematic search of all relevant articles. Results: Males have consistently an earlier onset, poorer premorbid functioning and different premorbid behavioral predictors. Males show more negative symptoms and cognitive deficits, with greater structural brain and neurophysiological abnormalities. Females display more affective symptoms, auditory hallucinations and persecutory delusions with more rapid and greater responsivity to antipsychotics in the pre-menopausal period but increased side effects. Course of illness is more favorable in females in the short- and middle-term, with less smoking and substance abuse. Families of males are more critical, and expressed emotion has a greater negative impact on males. There are no clear sex differences in family history, obstetric complications, minor physical anomalies and neurological soft signs. Conclusion: This review supports the presence of significant differences between schizophrenic males and females arising from the interplay of sex hormones, neurodevelopmental and psychosocial sex differences.

    Assessing motivation to quit smoking in people with mental illness: a review

    ADDICTION, Issue 5 2009
    Ranita Siru
    ABSTRACT Background People with mental health (MH) disorders smoke at higher rates, are more nicotine-dependent and suffer greater morbidity and mortality from smoking-related illnesses than the general population. Helping these people to quit smoking is a public health priority; however, many MH professionals assume that those with mental illness are not motivated to quit. Objectives To use predetermined criteria to identify, review critically and evaluate empirically all English language, peer-reviewed data on motivation to quit smoking in MH populations. Methods A systematic search was conducted and key data on subject characteristics, measures of motivation and other variables abstracted. ,2 analyses were used to compare motivation between MH and general populations, between in-patients and out-patients and between people with depression and people with psychotic disorders. Results Evidence suggests that people with MH disorders are as motivated to quit smoking as the general population, although those with psychotic disorders may be less motivated than individuals with depression. Although readiness to cease smoking was assessed in 14 studies, only two evaluated motivation to quit smoking in in-patient populations. Conclusions People with MH disorders are motivated to quit smoking, although more research is needed looking at in-patient populations. The commonly held false belief that people with MH disorders are not motivated to cease smoking means that opportunities to encourage smoking cessation among this disenfranchised group are being missed.

    A systematic review of the epidemiology of status epilepticus

    EUROPEAN JOURNAL OF NEUROLOGY, Issue 12 2004
    R. F. M. Chin
    Population-based data on the incidence, aetiology, and mortality associated with status epilepticus (SE) are required to develop preventative strategies for SE. Through a systematic review, we aimed to assess the methodological quality as well as similarities, and differences between available population based studies in order to arrive at conclusions on the epidemiology of SE. All population-based studies where primary outcome was incidence, aetiology or mortality of SE were identified through a systematic search and synthesized. Methodological quality of studies were independently rated by two examiners using a unique scoring system. Seven population-based projects on SE yielding nine published reports and five abstracts were reviewed. Quality scores were in the range of 19,34 with a possible maximum of 40 (kappa scores 0.67,1.0). The incidence of SE has a bimodal distribution with peaks in children aged less than a year and the elderly. Most SE were acute symptomatic. Short-term mortality was 7.6,22% and long-term mortality was 43%. Age and aetiology were the major determinants of mortality. There are few population-based studies on SE but most are of good quality. Most studies are primarily or exclusively based on adult populations. There is limited information on the association of ethnicity and socio-economic status and SE. [source]


    Molecular characterization of the spectrum of genomic deletions in the mismatch repair genes MSH2, MLH1, MSH6, and PMS2 responsible for hereditary nonpolyposis colorectal cancer (HNPCC)

    GENES, CHROMOSOMES AND CANCER, Issue 2 2005
    Heleen van der Klift
    A systematic search by Southern blot analysis in a cohort of 439 hereditary nonpolyposis colorectal cancer (HNPCC) families for genomic rearrangements in the main mismatch repair (MMR) genes, namely, MSH2, MLH1, MSH6, and PMS2, identified 48 genomic rearrangements causative of this inherited predisposition to colorectal cancer in 68 unrelated kindreds. Twenty-nine of the 48 rearrangements were found in MSH2, 13 in MLH1, 2 in MSH6, and 4 in PMS2. The vast majority were deletions, although one previously described large inversion, an intronic insertion, and a more complex rearrangement also were found. Twenty-four deletion breakpoints have been identified and sequenced in order to determine the underlying recombination mechanisms. Most fall within repetitive sequences, mainly Alu repeats, in agreement with the differential distribution of deletions between the MSH2 and MLH1 genes: the higher number and density of Alu repeats in MSH2 corresponded with a higher incidence of genomic rearrangement at this disease locus when compared with other MMR genes. Long interspersed nuclear element (LINE) repeats, relatively abundant in, for example, MLH1, did not seem to contribute to the genesis of the deletions, presumably because of their older evolutionary age and divergence among individual repeat units when compared with short interspersed nuclear element (SINE) repeats, including Alu repeats. Moreover, Southern blot analysis of the introns and the genomic regions flanking the MMR genes allowed us to detect 6 novel genomic rearrangements that left the coding region of the disease-causing gene intact. These rearrangements comprised 4 deletions upstream of the coding region of MSH2 (3 cases) and MSH6 (1 case), a 2-kb insertion in intron 7 of PMS2, and a small (459-bp) deletion in intron 13 of MLH1. The characterization of these genomic rearrangements underlines the importance of genomic deletions in the etiology of HNPCC and will facilitate the development of PCR-based tests for their detection in diagnostic laboratories. © 2005 Wiley-Liss, Inc.

    Efficacy of recombinant activated factor VII vs. activated prothrombin complex concentrate for patients suffering from haemophilia complicated with inhibitors: a Bayesian meta-regression

    HAEMOPHILIA, Issue 2 2009
    M. J. TREUR
    Summary., The optimal on-demand treatment of joint bleeds in haemophilia patients with inhibitors is a source of debate, with studies reporting various efficacy levels for different drugs and dosage regimens. To analyse, in a unified Bayesian meta-regression model, the published efficacy of recombinant activated factor VII (rFVIIa) and/or activated prothrombin complex concentrate (aPCC) as on-demand treatments for joint bleeds in haemophilia patients with inhibitors. A systematic search was carried out to identify studies reporting on dosage and efficacy of rFVIIa and aPCC in the treatment of joint bleeds in the target patient population. Data were abstracted and included in the model and adjusted for potential sources of heterogeneity. Pooled efficacy levels for typical rFVIIa and aPCC regimens were estimated. Seventeen studies, collectively reporting on >2000 joint bleeds, were included. Medication type combined with dosage was the only significant explanatory parameter. The model predicts that a typical regimen of 90 ,g kg,1 rFVII repeated every 3 h if needed results in cumulative joint bleed resolution of 66%, 88% and 95% after 12, 24 and 36 h, respectively. In comparison, a typical regimen of 75 IU kg,1 aPCC repeated every 12 h if needed results in cumulative joint bleed resolution of 39%, 62% and 76%, respectively. These differences were statistically significant and were also robust in sensitivity analyses. This analysis suggests that a typical rFVIIa regimen will resolve joint bleeds more effectively than a typical aPCC regimen after 12, 24 and 36 h. [source]


    Systematic review of the perceptions and experiences of accessing health services by adult victims of domestic violence

    HEALTH & SOCIAL CARE IN THE COMMUNITY, Issue 1 2008
    Louise Robinson RGN RHV BSc (Hons) MSc
    Abstract This systematic review synthesises evidence on the perceptions and experiences of adult victims of domestic violence when accessing healthcare services. The review was concerned with disclosure of domestic violence by adult victims when accessing health services, the responses of healthcare professionals to these victims, victims' perceived barriers to support, and the appropriateness of support and referrals. These aims required the review to focus on studies using in-depth qualitative methods to explore victims' perceptions and experiences. A comprehensive systematic search of 12 databases was carried out in June/July 2005. Application of the review protocol and inclusion criteria resulted in 10 studies (conducted in the UK, USA and Australia) being considered eligible for the review. Data were extracted from these studies and a quality assessment completed. Thematic analysis was carried out to enable the identification of recurrent themes within the included studies. Findings indicate that victims of domestic violence experience difficulties when accessing healthcare services. Victims perceive that these difficulties can be attributed to inappropriate responses by healthcare professionals, discomfort with the healthcare environment, perceived barriers to disclosing domestic violence, and a lack of confidence in the outcomes of disclosure to a health professional. The methodological quality of included studies was variable, but no papers were rejected based on quality issues. These results can contribute to and inform a comprehensive assessment of the experiences of adult victims of domestic violence when accessing healthcare services. The health service is in a unique position to contribute towards the assessment and identification of domestic violence and to provide access to appropriate support. The messages of this study are important for policy-makers and practitioners. [source]


    Health-related quality of life and eating disorders: A review and update

    INTERNATIONAL JOURNAL OF EATING DISORDERS, Issue 2 2009
    Scott G. Engel PhD
    Abstract Objective: The aim of this article is to provide a narrative review of empirical studies related to health-related quality of life (HRQOL) and eating disorders and to report recent changes in the measurement of HRQOL in eating disorders. Method: Twenty-five articles of central importance to the topic were identified in a systematic search of six databases. All articles were selected based on a consensus relevancy rating process. Key themes were extracted from the articles and validated by all authors. Results: We identify six themes in the extant empirical literature. Discussion: We discuss these six themes and review them in light of the fact that they are identified in studies using only generic measures of HRQOL. Four recently developed disease-specific HRQOL measures specific to patients with eating disorder are discussed. © 2008 by Wiley Periodicals, Inc. Int J Eat Disord 2009 [source]


    EVIDENCE SYNTHESIS: Appropriateness of using a symbol to identify dementia and/or delirium

    INTERNATIONAL JOURNAL OF EVIDENCE BASED HEALTHCARE, Issue 3 2010
    Sonia Hines RN BN
    Abstract Aim, The main objective of this systematic review was to evaluate any published and unpublished evidence regarding the appropriateness of developing a symbol for dementia and/or delirium, which could be used in a variety of settings to indicate that a person has dementia and/or delirium. Methods, Using the methods of the Joanna Briggs Institute, we conducted a systematic search of a wide range of databases, Internet resources and unpublished literature. Papers meeting the inclusion criteria were critically appraised by two independent reviewers. Data were extracted, using the standardised tool from the Joanna Briggs Institute, from those papers considered to be of sufficient quality. Because of significant methodological heterogeneity, no meta-analysis was possible and results are presented narratively instead. Results, From a total of 37 retrieved papers, 18 were found to be of sufficient relevance and quality to be included in the review. There was general consensus among the literature that a symbol for dementia is appropriate in the acute care setting. It was also clear from the research that an abstract symbol, as opposed to one that explicitly attempts to depict dementia, was most acceptable to staff, people with dementia and their carers. Conclusions, Both staff and health consumers seem to have largely positive perceptions and attitudes towards the use of a symbol for dementia. Families and carers of people with dementia are frequently concerned about their loved one wandering away and becoming lost and unable to identify themselves, and these concerns seem to outweigh any reservations they hold about the use of a symbol or some other identifier. In healthcare settings the use of symbols to indicate special needs seems well established and widely accepted. However, regarding the use of a symbol for dementia in the broader community, there remain concerns about issues such as stigmatisation and the potential for victimisation of this vulnerable population and so further research is indicated.

    Effectiveness of arthroscopic versus open surgical stabilisation for the management of traumatic anterior glenohumeral instability

    INTERNATIONAL JOURNAL OF EVIDENCE BASED HEALTHCARE, Issue 2 2007
    Choong Ng BMedSci(Melb)
    Abstract Background, Anterior instability is a frequent complication following a traumatic glenohumeral dislocation. Frequently the underlying pathology associated with recurrent instability is a Bankart lesion. Surgical correction of Bankart lesions and other associated pathology is the key to successful treatment. Open surgical glenohumeral stabilisation has been advocated as the gold standard because of consistently low postoperative recurrent instability rates. However, arthroscopic glenohumeral stabilisation could challenge open surgical repair as the gold standard treatment for traumatic anterior glenohumeral instability. Objectives, Primary evidence that compared the effectiveness of arthroscopic versus open surgical glenohumeral stabilisation was systematically collated regarding best-practice management for adults with traumatic anterior glenohumeral instability. Search strategy, A systematic search was performed using 14 databases: MEDLINE, Cumulative Index of Nursing and Allied Health (CINAHL), Allied and Complementary Medicine Database (AMED), ISI Web of Science, Expanded Academic ASAP, Proquest Medical Library, Evidence Based Medicine Reviews, Physiotherapy Evidence Database, TRIP Database, PubMed, ISI Current Contents Connect, Proquest Digital Dissertations, Open Archives Initiative Search Engine, Australian Digital Thesis Program. Studies published between January 1984 and December 2004 were included in this review. No language restrictions were applied. Selection criteria, Eligible studies were those that compared the effectiveness of arthroscopic versus open surgical stabilisation for the management of traumatic anterior glenohumeral instability, which had more than 2 years of follow up and used recurrent instability and a functional shoulder questionnaire as primary outcomes. Studies that used non-anatomical open repair techniques, patient groups that were specifically 40 years or older, or had multidirectional instability or other concomitant shoulder pathology were excluded. Data collection and analysis, Two independent reviewers assessed the eligibility of each study for inclusion into the review, the study design used and its methodological quality. Where any disagreement occurred, consensus was reached by discussion with an independent researcher. Studies were assessed for homogeneity by considering populations, interventions and outcomes. Where heterogeneity was present, synthesis was undertaken in a narrative format; otherwise a meta-analysis was conducted. Results, Eleven studies were included in the review. Two were randomised controlled trials. Evidence comparing arthroscopic and open surgical glenohumeral stabilisation was of poor to fair methodological quality. Hence, the results of primary studies should be interpreted with caution. Observed clinical heterogeneity in populations and outcomes was highlighted and should be considered when interpreting the meta-analysis. Authors also used variable definitions of recurrent instability and a variety of outcome measures, which made it difficult to synthesise results. When comparable data were pooled, there were no significant differences (P > 0.05) between the arthroscopic and open groups with respect to recurrent instability rates, Rowe score, glenohumeral external rotation range and complication rates. Conclusions, Statistically, it appears that both surgical techniques are equally effective in managing traumatic anterior glenohumeral instability. In light of the methodological quality of the included studies, it is not possible to validate arthoscopic stabilisation to match open surgical stabilisation as the gold standard treatment. Further research using multicentred randomised controlled trials with sufficient power and instability-specific questionnaires with sound psychometric properties is recommended to build on current evidence. The choice of treatment should be based on multiple factors between the clinician and the patient. [source]


    Don't seize the day hospital!

    INTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 7 2005
    Recent research on the effectiveness of day hospitals for older people with mental health problems
    Abstract Background Day hospital (DH) care remains a core component of mental health services for older people. However, there has been an ongoing debate about the effectiveness and value for money of DHs in comparison to day centres (DC). Aim The aim was to review the recent research on the effectiveness of day hospitals for older people with mental health problems. Method A systematic search of relevant research literature over the last decade using the major electronic healthcare databases examining the quality and effectiveness of mental health DHs for older people. Results In the last decade the evidence for the effectiveness of DHs has continued to increase, but still lags behind research on DHs in general adult psychiatry and geriatric medicine. The review found that DHs appear effective at assessing and meeting needs and that a systematic approach to evaluating quality can be used to improve services. Conclusion Recent research supports the effectiveness of day hospitals, but further studies are needed in order to provide a more robust evidence base. Copyright © 2005 John Wiley & Sons, Ltd.

    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]


    The transversus abdominis plane block: a valuable option for postoperative analgesia?

    ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 5 2010
    A topical review
    The transversus abdominis plane (TAP) block is a newly described peripheral block involving the nerves of the anterior abdominal wall. The block has been developed for post-operative pain control after gynaecologic and abdominal surgery. The initial technique described the lumbar triangle of Petit as the landmark used to access the TAP in order to facilitate the deposition of local anaesthetic solution in the neurovascular plane. Other techniques include ultrasound-guided access to the neurovascular plane via the mid-axillary line between the iliac crest and the costal margin, and a subcostal access termed the ,oblique subcostal' access. A systematic search of the literature identified a total of seven randomized clinical trials investigating the effect of TAP block on post-operative pain, including a total of 364 patients, of whom 180 received TAP blockade. The surgical procedures included large bowel resection with a midline abdominal incision, caesarean delivery via the Pfannenstiel incision, abdominal hysterectomy via a transverse lower abdominal wall incision, open appendectomy and laparoscopic cholecystectomy. Overall, the results are encouraging and most studies have demonstrated clinically significant reductions of post-operative opioid requirements and pain, as well as some effects on opioid-related side effects (sedation and post-operative nausea and vomiting). Further studies are warranted to support the findings of the primary published trials and to establish general recommendations for the use of a TAP block. [source]


    Aetiology of molar,incisor hypomineralization: a critical review

    INTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 2 2009
    FELICITY CROMBIE
    Objective., The objective of this study was to assess the strength of evidence for the aetiology of molar,incisor hypomineralization (MIH), often as approximated by demarcated defects. Method., A systematic search of online medical databases was conducted with assessment of titles, abstracts, and finally full articles for selection purposes. The level and quality of evidence were then assessed for each article according to Australian national guidelines. Results., Of 1123 articles identified by the database search, 53 were selected for review. These covered a variety of potential aetiological factors, some of which were grouped together for convenience. The level of evidence provided by the majority of papers was low and most did not specifically investigate MIH. There was moderate evidence that polychlorinated biphenyl/dioxin exposure is involved in the aetiology of MIH; weak evidence for the role of nutrition, birth and neonatal factors, and acute or chronic childhood illness/treatment; and very weak evidence to implicate fluoride or breastfeeding. Conclusion., There is currently insufficient evidence in the literature to establish aetiological factor/s relevant for MIH. Improvements in study design, as well as standardization of diagnostic and examination protocols, would improve the level and strength of evidence. [source]
