    Obsessive,compulsive disorder: a review of the diagnostic criteria and possible subtypes and dimensional specifiers for DSM-V,

    DEPRESSION AND ANXIETY, Issue 6 2010
    James F. Leckman M.D.
    Abstract Background: Since the publication of the DSM-IV in 1994, research on obsessive,compulsive disorder (OCD) has continued to expand. It is timely to reconsider the nosology of this disorder, assessing whether changes to diagnostic criteria as well as subtypes and specifiers may improve diagnostic validity and clinical utility. Methods: The existing criteria were evaluated. Key issues were identified. Electronic databases of PubMed, ScienceDirect, and PsycINFO were searched for relevant studies. Results: This review presents a number of options and preliminary recommendations to be considered for DSM-V. These include: (1) clarifying and simplifying the definition of obsessions and compulsions (criterion A); (2) possibly deleting the requirement that people recognize that their obsessions or compulsions are excessive or unreasonable (criterion B); (3) rethinking the clinical significance criterion (criterion C) and, in the interim, possibly adjusting what is considered "time-consuming" for OCD; (4) listing additional disorders to help with the differential diagnosis (criterion D); (5) rethinking the medical exclusion criterion (criterion E) and clarifying what is meant by a "general medical condition"; (6) revising the specifiers (i.e., clarifying that OCD can involve a range of insight, in addition to "poor insight," and adding "tic-related OCD"); and (7) highlighting in the DSM-V text important clinical features of OCD that are not currently mentioned in the criteria (e.g., the major symptom dimensions). Conclusions: A number of changes to the existing diagnostic criteria for OCD are proposed. These proposed criteria may change as the DSM-V process progresses.

    Brief screening questionnaires to identify problem drinking during pregnancy: a systematic review

    ADDICTION, Issue 4 2010
    Ethel Burns
    ABSTRACT Aims Although prenatal screening for problem drinking during pregnancy has been recommended, guidance on screening instruments is lacking. We investigated the sensitivity, specificity and predictive value of brief alcohol screening questionnaires to identify problem drinking in pregnant women. Methods Electronic databases from their inception to June 2008 were searched, as well as reference lists of eligible papers and related review papers. We sought cohort or cross-sectional studies that compared one or more brief alcohol screening questionnaire(s) with reference criteria obtained using structured interviews to detect ,at-risk' drinking, alcohol abuse or dependency in pregnant women receiving prenatal care. Results Five studies (6724 participants) were included. In total, seven instruments were evaluated: TWEAK (Tolerance, Worried, Eye-opener, Amnesia, Kut down), T-ACE [Take (number of drinks), Annoyed, Cut down, Eye-opener], CAGE (Cut down, Annoyed, Guilt, Eye-opener], NET (Normal drinker, Eye-opener, Tolerance), AUDIT (Alcohol Use Disorder Identification Test), AUDIT-C (AUDIT-consumption) and SMAST (Short Michigan Alcohol Screening Test). Study quality was generally good, but lack of blinding was a common weakness. For risk drinking sensitivity was highest for T-ACE (69-88%), TWEAK (71,91%) and AUDIT-C (95%), with high specificity (71,89%, 73,83% and 85%, respectively). CAGE and SMAST performed poorly. Sensitivity of AUDIT-C at score ,3 was high for past year alcohol dependence (100%) or alcohol use disorder (96%) with moderate specificity (71% each). For life-time alcohol dependency the AUDIT at score ,8 performed poorly. Conclusion T-ACE, TWEAK and AUDIT-C show promise for screening for risk drinking, and AUDIT-C may also be useful for identifying alcohol dependency or abuse. However, their performance as stand-alone tools is uncertain, and further evaluation of questionnaires for prenatal alcohol use is warranted. [source]


    Does opioid substitution treatment in prisons reduce injecting-related HIV risk behaviours?

    ADDICTION, Issue 2 2010
    A systematic review
    ABSTRACT Objectives To review systematically the evidence on opioid substitution treatment (OST) in prisons in reducing injecting-related human immunodeficiency virus (HIV) risk behaviours. Methods Systematic review in accordance with guidelines of the Cochrane Collaboration. Electronic databases were searched to identify studies of prison-based opioid substitution treatment programmes that included assessment of effects of prison OST on injecting drug use, sharing of needles and syringes and HIV incidence. Published data were used to calculate risk ratios for outcomes of interest. Risk ratios were not pooled due to the low number of studies and differences in study designs. Results Five studies were included in the review. Poor follow-up rates were reported in two studies, and representativeness of the sample was uncertain in the remaining three studies. Compared to inmates in control conditions, for treated inmates the risk of injecting drug use was reduced by 55,75% and risk of needle and syringe sharing was reduced by 47,73%. No study reported a direct effect of prison OST on HIV incidence. Conclusions There may be a role for OST in preventing HIV transmission in prisons, but methodologically rigorous research addressing this question specifically is required. OST should be implemented in prisons as part of comprehensive HIV prevention programmes that also provide condoms and sterile injecting and tattooing equipment. [source]


    Appraisal of caregiving burden, expressed emotion and psychological distress in families of people with eating disorders: A systematic review

    EUROPEAN EATING DISORDERS REVIEW, Issue 5 2009
    Maria Jose Zabala
    Abstract The purpose of this review is to appraise the literature regarding psychological distress, burden and expressed emotion (EE) in caregivers of people with eating disorders (EDs). Electronic databases were searched up until October 2008. Selected studies contained carers of people with ED and employed one measure of burden, EE or psychological distress. Twenty studies were identified measuring psychological distress burden and EE. Most of the studies examined these features in families of anorexic patients. The majority of the studies found high levels of psychological distress, burden and EE in this population. Only few studies included a control group. Carers of people with ED presented high levels of psychological distress and burden. ED carers tend to have levels of EE resembling that found in families of depressed patients, rather than schizophrenic patients. There is some evidence (particularly for EE) that these factors can impact the outcome of ED. Copyright © 2009 John Wiley & Sons, Ltd and Eating Disorders Association. [source]


    Seen but not heard: a systematic review of the place of the child in 21st-century dental research

    INTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 5 2007
    ZOE MARSHMAN
    Background., The position of children in society has changed with increasing emphasis on children's rights and child-centred services. This study aimed to describe the extent to which contemporary oral health research has been conducted with or on children. Design., A systematic review of the child dental literature from 2000,2005 was conducted. A purposive sample was used to develop categories describing the level of involvement of children in research. Four main categories were developed: children as the objects of research, proxies used on behalf of children, children as the subjects of research with some involvement and children as active participants with their perspectives explored. Electronic databases were searched and exclusion criteria applied. Each of the resulting papers was examined and categorised. The frequency distribution in each category and the distribution of these categories according to subject were calculated. Results., The search revealed 3266 papers after application of the exclusion criteria. Of these, 87.1% were categorised as research where children were used as objects, 5.7% were found to involve proxies (parents or clinicians), 7.0% involved children to some extent and 0.3% involved children actively. Conclusion., Most oral health research is conducted on children, in future research should strive to be conducted with children, involving them as fully as possible. [source]


    The feasibility of providing community pharmacy-based services for alcohol misuse: A literature review

    INTERNATIONAL JOURNAL OF PHARMACY PRACTICE, Issue 4 2009
    Dr Margaret C. Watson
    Abstract Objectives Excessive consumption of alcohol is a major public health concern. The use of community pharmacies and pharmacists as sources of public health information and services is gaining greater recognition. The objective of this review was to provide an overview of the evidence on the feasibility, effectiveness and acceptability of providing community pharmacy-based services to address the excessive consumption of alcohol. Methods Electronic databases were searched for the period 1996,2007 to identify relevant evidence. Searches were also conducted of relevant pharmacy and addiction journals. Information was sought from key contacts in pharmacy and alcohol research. Studies were included if they were conducted in a community pharmacy setting. Key findings The review comprised three feasibility studies which included 14 pharmacies and 500 customers. Non-significant reductions in alcohol consumption were reported with two studies following brief interventions by pharmacists. Between 30% and 53% of pharmacy customers were identified as having hazardous or harmful drinking behaviour. Customer opinion of the pharmacy-based alcohol services was not reported. Conclusions There has been little empirical evaluation of the effectiveness of community pharmacy-based services for alcohol misuse. The evidence presented in this review suggests that community pharmacy-based screening is feasible. Organisations and individuals involved with tackling excessive alcohol consumption should consider the inclusion of community pharmacies and pharmacists as part of their strategies to address this problem. Large-scale studies are needed to evaluate the short- and long-term effects and cost-effectiveness of community pharmacy-based interventions to reduce excessive alcohol consumption, as well as to explore the acceptability of the service to users.

    Consumers' views on generic medicines: A review of the literature

    INTERNATIONAL JOURNAL OF PHARMACY PRACTICE, Issue 2 2009
    Mohamed A. A. Hassali
    Abstract Objectives To review the literature on consumers' knowledge, attitudes and opinions of the use of generic medicines. Method A narrative review of studies conducted from 1970 to 2008 on consumers' perceptions and views towards generic medicines was performed. An extensive literature search was undertaken using indexing services available at the authors' institution library. The following keywords were used for the search: brand, generic, multisource, medications, medicines, drugs, pharmaceuticals and consumers, customers, and patients. Electronic databases searched were Medline, Inside Web, ISI Web of Knowledge, Science Direct, Springer Link, JSTOR, Proquest, Ebsco Host and Google Scholar. These electronic databases were searched for full text papers published in English from 1970 to October 2008. Key findings Twenty studies were identified. Eleven were from the USA, four were from Europe, two were from Canada and one each was from Australia, Brazil and Malaysia. In general, consumers showed mixed reactions towards the use of generic medicines. This was evident from the divergence of views observed by country development level, consumers' socioeconomic characteristics, drug product characteristics, pharmaceutical reimbursement system, policy environment, contact with health care professionals, past experience with medications, and knowledge of the seriousness of a medical condition. Conclusions Patient confidence and knowledge pertaining to generic medicines use have increased over the past four decades, especially in developed countries. Mass educational efforts, financial incentives, and greater communication among patients and health care professionals were seen as major drivers to the uptake of generic medicines among consumers.

    Repeat dispensing of prescriptions in community pharmacies: a systematic review of the UK literature

    INTERNATIONAL JOURNAL OF PHARMACY PRACTICE, Issue 1 2006
    Charles W. Morecroft Research associate
    Objective To identify, review and evaluate the published literature that focused on the impact of repeat dispensing in community pharmacies in the United Kingdom. Method Electronic databases (e.g. Medline, Embase and CINAHL) were searched from 1992 to May 2005. This was supplemented by searching PJ-online, IJPP online conference abstracts and the bibliographies of retrieved articles. Analysis of the findings explored the quality of the assessed papers, stakeholders' perceptions of repeat dispensing, the impact on professional relationships and workload, quality of care and prescription cost savings. Key findings Four randomised controlled trials (RCTs) and one before-and-after study were identified; most studies also incorporated a qualitative component. The findings indicated that patients' satisfaction with repeat dispensing was high, mainly as the service was seen as more convenient and time saving. While pharmacists considered that their relationship with patients had improved, one study found that patients did not necessarily agree and considered that pharmacists still remained in their dispensaries. Quality of care was considered in two RCTs, which indicated that more adverse reactions and compliance issues were identified in the intervention group. However, no direct comparisons were reported in differences in rates between intervention and control groups. Likewise, it was not possible to determine if any of the reported cost savings were solely attributable to repeat dispensing, as direct comparisons between groups were not reported. Conclusions Definitive conclusions about the effectiveness and impact of repeat dispensing are difficult to draw given a lack of transparency and systematicity when reporting these studies. Nevertheless, the findings suggest that there are high levels of patient satisfaction with the service. Likewise, it was not possible to draw conclusions about the possible savings on the NHS drug budget. Important policy decisions are being made about the implementation of repeat dispensing; however they are currently been made in a vacuum of adequate information. [source]


    Meta-Analysis of Psychosocial Interventions for Caregivers of People with Dementia

    JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 5 2003
    FRACP, FRANZCP, Henry Brodaty MD
    OBJECTIVES: To review published reports of interventions for caregivers (CGs) of persons with dementia, excluding respite care, and provide recommendations to clinicians. DESIGN: Meta-analytical review. Electronic databases and key articles were searched for controlled trials, preferably randomized, published in English from 1985 to 2001 inclusive. Thirty studies were located and scored according to set criteria, and the interventions' research quality and clinical significance were judged. SETTING: Home or noninstitutional environment. PARTICIPANTS: Informal CGs,persons providing unpaid care at home or in a noninstitutional setting. MEASUREMENTS: The primary measures were psychological morbidity and burden. Other varied outcome measures such as CG coping skills and social support were combined with measures of psychological distress and burden to form a main outcome measure. RESULTS: The quality of research increased over the 17 years. Results from 30 studies (34 interventions) indicated, at most-current follow-up, significant benefits in caregiver psychological distress (random effect size (ES) = 0.31; 95% confidence interval (CI) = 0.13,0.50), caregiver knowledge (ES = 0.51; CI = 0.05,0.98), any main caregiver outcome measure (ES = 0.32; CI = 0.15,0.48), and patient mood (ES = 0.68; CI = 0.30,1.06), but not caregiver burden (ES = 0.09; CI = ,0.09,0.26). There was considerable variability in outcome, partly because of differences in methodology and intervention technique. Elements of successful interventions could be identified. Success was more likely if, in addition to CGs, patients were involved. Four of seven studies indicated delayed nursing home admission. CONCLUSION: Some CG interventions can reduce CG psychological morbidity and help people with dementia stay at home longer. Programs that involve the patients and their families and are more intensive and modified to CGs' needs may be more successful. Future research should try to improve clinicians' abilities to prescribe interventions. [source]


    Literature review: should antipyretic therapies routinely be administered to patient fever?

    JOURNAL OF CLINICAL NURSING, Issue 17-18 2010
    Jane V Carey
    Aims and objectives., To determine whether the practices of routinely treating fever with antipyretic medications or physical cooling methods are supported by the literature. Background., Fever is one of the commonest symptoms presented to caregivers. Previous research suggests that treating fever with antipyretic medications or physical cooling methods is often routine practice. This article considers that fever and the febrile response may have been preserved through evolution because of its advantage for host defences and that fever may have an adaptive value. It is questioned whether the administration of antipyretic therapies could prolong the duration of illness, as interventions to lower body temperature are acting against the body's natural response to infection. Design., Literature review. Method., Electronic databases and the Internet were searched, supplemented by citation tracking. Articles were eligible if the participants studied had received pharmacological or physical cooling interventions to reduce their body temperature during fever. The interventions were evaluated in regard to whether they prolonged duration of illness. Results., Results were inconsistent. None of the studies found that antipyretic therapies reduced duration of illness in patients with fever. Evidence suggests that antipyretic therapies do not reduce the duration of illness, but can prolong it. Conclusions., The evidence on which to base recommendations for practice is weak but does not support the current practice of administering antipyretic therapies routinely to patients with fever. Physical cooling methods alone should never be used. Nurses should assess patients with fever on an individualised basis and use antipyretic therapies selectively. Relevance to clinical practice., The administration of antipyretics to patients with fever is an important issue, and nurses are at the forefront of decision-making. Evidence-based care delivery is expected by the NMC. A protocol to assist decision-making when caring for patients with pyrexia is suggested. [source]


    The experience of living with a chronic illness during adolescence: a critical review of the literature

    JOURNAL OF CLINICAL NURSING, Issue 23 2008
    Rachel M Taylor
    Aims., To identify and critique literature on the adolescent lived experience of chronic illness; describe the lived experience; and to make recommendations for clinical practice. Background., Young people with chronic illness have the same developmental issues as those who are healthy. However, development can be disrupted by treatment and repeated hospitalisation. While the physical consequences of chronic illness on development have been established, the subjective personal experience is less known. Design., Literature review. Methods., Electronic databases and hand searches were made of the literature published between January 1990,September 2007. Literature was eligible for inclusion if it involved adolescents between 10,19 years, and published in English and used qualitative methods of data collection. Methodological quality was assessed using the criteria described by Cesario et al. [Journal of Obstetrics, Gynaecology and Neonatal Nursing 31 (2002) 31]. Conclusions., Twenty studies were identified involving young people with a wide variety of chronic illnesses. The study quality was variable, however, generally the majority was assessed as being good or fair. Seven common themes were found between the identified studies: developing and maintaining friendships; being normal/getting on with life; the importance of family; attitude to treatment; experiences of school; relationship with the healthcare professionals; and the future. Relevance to practice., As there was commonality in themes between studies strategies to lessen the burden of chronic illness during adolescence do not necessarily need to be disease specific. Nurses need to focus on treating the young person rather than their illness. [source]


    Efficacy and safety of over-the-counter analgesics in the treatment of common cold and flu

    JOURNAL OF CLINICAL PHARMACY & THERAPEUTICS, Issue 4 2006
    R. Eccles BSc PhD DSc
    Summary Rationale:, Common cold and flu are the most common human illnesses, and over-the-counter (OTC) analgesics are widely used to treat the pain and fever symptoms. Despite the every day use of these analgesic there is little information available in the literature on the efficacy and safety of these medicines in treating colds and flu symptoms. The aim of this review was to determine the safety and efficacy of the analgesics, aspirin, paracetamol and aspirin for the treatment of colds and flu. Methods:, Electronic databases and a personal database were searched and the information retrieved together with information from relevant textbooks has been integrated in the review. Results:, The literature search established that there is relatively little information on the use of analgesics in treating colds and flu and that much of the safety and efficacy data must be related to other pain and fever models. The review establishes that aspirin, paracetamol and ibuprofen are safe in OTC doses and that there is no evidence for any difference between the medicines as regards efficacy and safety for treatment of colds and flu (except in certain cases such as the use of aspirin in feverish children). There is also no evidence that these medicines prolong the course of colds and flu by any effect on the immune system or by reducing fever. Conclusion:, Despite the lack of clinical data on the safety and efficacy of analgesics for the treatment of colds and flu symptoms a case can be made that these medicines are safe and effective for treatment of these common illnesses.

    A systematic review of multivitamin and multimineral supplementation for infection

    JOURNAL OF HUMAN NUTRITION & DIETETICS, Issue 3 2006
    A. I. Stephen
    Abstract Background, Infections are major causes of morbidity and mortality worldwide. Micronutrients have important functions in the body's immune system. This systematic review examined the evidence from randomized controlled trials (RCTs) on whether multivitamin and multimineral supplementation is effective in reducing infection. Methods, Electronic databases searched: Cochrane Controlled Trials Register, EMBASE, MEDLINE, BIOSIS, CAB abstracts. Hand searching of nutrition journals and reference lists was carried out. RCTs and quasi-randomized trials of supplementation of adults with at least two vitamins or minerals or a combination were selected. Study results were combined in meta-analysis plots where appropriate. Results, Twenty studies were included in the review. Small numbers were available for each meta-analysis. Results are presented here without the Chandra group studies. No significant difference was found in the number of episodes of infection in older people (,65 years) between those supplemented and those not supplemented; (WMD) 0.06 [95% confidence interval (CI) ,0.04, 0.16], P = 0.25. In other adults groups, there were significantly less episodes of infection in those supplemented; (WMD) ,1.20 (95% CI ,2.08, ,0.32), P = 0.008. There was no significant difference between those older people supplemented and those not supplemented in the number with at least one infection; relative risk (RR) 0.98 (95% CI 0.86, 1.11), P = 0.77. Similarly, there was no significant difference in the numbers in other adult groups who had at least one episode of infection between those supplemented and those taking placebo; (RR) 0.81 (95% CI 0.65, 1.00), P = 0.06. Subgroup analyses suggested that supplemented people aged 65 years or over may benefit more if they are undernourished and supplemented for over 6 months, WMD ,0.67 infections (95% CI ,1.24, ,0.10), P = 0.02. Conclusion, Further large trials are needed, particularly in undernourished older people. Trials of supplementation periods of over 6 months are recommended. [source]


    Prevalence of Xerostomia in Population-based Samples: A Systematic Review

    JOURNAL OF PUBLIC HEALTH DENTISTRY, Issue 2 2006
    M.F. Orellana DDS
    Abstract The consequences of xerostomia on oral health have been studied for decades; however, the actual prevalence of this disorder on the general population remains controversial. The purpose of this systematic review was to determine the prevalence of xerostomia in population-based samples. Electronic databases were screened for relevant articles and reference lists of pertinent articles were also hand-searched. Thirteen articles meeting the final inclusion criteria were identified. Based on the definition of xerostomia used in this review, only publications including a subjective diagnosis of the disorder were included. All of the self-repotted diagnoses were achieved through a questionnaire either by mail, telephone, interview or self-administered by the patient. There was a variation across papers regarding number and content of the questions as well as guidelines for the diagnosis of xerostomia (i.e. answer yes to one or more than one question). The prevalence of xerostomia in the selected articles ranged from 0.9% to 64.8%. The majority of these studies were performed in Scandinavia. In 9 of the articles, the studied samples were 50 years and older. None of the studies evaluated the prevalence xerostomia among individuals younger than 18 years. Based on these observations, it can be concluded that there is a need for population-based studies on prevalence of xerostomia in regions other than Scandinavia. A standardized protocol to diagnose xerostomia needs to be developed. Patient-perceived treatment needs and impact on quality of life should be included to have a complete picture of public health implications of the disease. [source]


    The Evaluation of School-Based Violence Prevention Programs: A Meta-Analysis,

    JOURNAL OF SCHOOL HEALTH, Issue 9 2008
    Hyoun-Kyoung Park-Higgerson PhD
    ABSTRACT Background:, Youth violence and related aggressive behaviors have become serious public health issues with physical, economic, social, and psychological impacts and consequences. This study identified and evaluated the characteristics of successful school-based violence prevention programs. Methods:, Twenty-six randomized controlled trial (RCT), school-based studies that were designed to reduce externalizing, aggressive, and violent behavior between the 1st and 11th grades were analyzed for assessing the effects of 5 program characteristics by comparing results of intervention groups to control groups (no intervention) after intervention using a meta-analysis. Electronic databases and bibliographies were systematically searched, and a standardized mean difference was used for analysis. Results:, There was no significant difference between interventions, although programs that used non,theory-based interventions, focused on at-risk and older children, and employed intervention specialists had slightly stronger effects in reducing aggression and violence. Interventions using a single approach had a mild positive effect on decreasing aggressive and violent behavior (effect size =,0.15, 95% CI =,0.29 to ,0.02, p = .03). Conclusions:, Unlike previous individual study findings, this meta-analysis did not find any differential effects for 4 of the 5 program characteristics. In addition, the significant effect noted was contrary to expectation, exemplifying the complexity of identifying effective program strategies. This study adds to the current literature by assessing the program characteristics of RCT studies in an effort to determine what factors may affect school-based violence prevention program success.

    Meta-analysis: antibiotic prophylaxis in elective laparoscopic cholecystectomy

    ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 10 2009
    H. ZHOU
    Summary Background, Current guidelines do not support routine antibiotic prophylaxis during elective laparoscopic cholecystectomy. However, routine antibiotic prophylaxis for elective laparoscopic cholecystectomy is still popular in many clinical settings. Aim, To evaluate the role of antibiotic prophylaxis in elective laparoscopic cholecystectomy. Methods, Electronic databases and manual bibliographical searches (updated to April 2008) were conducted. A meta-analysis of all trials evaluating antibiotic prophylaxis in elective laparoscopic cholecystectomy was performed. Results, Fifteen trials were included, involving 2961 patients. After pooling all the trials, 48 wound infections occurred (48/2961, 1.62%), 22 in antibiotic prophylaxis group (22/1494, 1.47%) and 26 in control group (26/1467, 1.77%). The pooled odds ratio (OR) was 0.79 (95%CI: 0.44, 1.41). Four major infections occurred (4/2961, 0.14%), 3 in antibiotic prophylaxis group (3/1494, 0.20%), and one in control group (1/1467, 0.07%). The pooled OR was 2.51 (95%CI: 0.35, 17.84). Fifteen distant infections occurred (15/2961, 0.51%), six in antibiotic prophylaxis group (6/1494, 0.40%) and nine in control group (9/1467, 0.61%). The pooled OR was 0.53 (95%CI: 0.19, 1.50). Sensitivity analyses also failed to support antibiotic prophylaxis's preventive effect. Conclusions, Considering the absent role of antibiotic prophylaxis in reducing the infectious complications, we suggest that antibiotic prophylaxis is unnecessary and should not be routinely used in low-risk elective laparoscopic cholecystectomy patients.

    Meta-analysis: efficacy of bovine lactoferrin in Helicobacter pylori eradication

    ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 7 2009
    A. SACHDEVA
    Summary Background, Several randomized-controlled trials (RCTs) have sought to determine the efficacy of bovine lactoferrin in Helicobacter pylori eradication with equivocal results. Aim, To evaluate the effect of bovine lactoferrin supplementation in H. pylori eradication. Methods, Electronic databases, reviews, bibliographies, abstracts and conference proceedings were searched. Included trials had to be randomized or quasi-randomized and controlled, using bovine lactoferrin in the intervention group, treating Helicobacter -infected subjects and evaluating eradication of H. pylori as an outcome. Results, The search identified five eligible RCTs (of 169). Data were available for 682 subjects (bovine lactoferrin group- n = 316; control group- n = 366). The pooled odds ratio (five studies) for eradication by intention-to-treat analysis was 2.22 (95% CI 1.44,3.44; P = 0.0003) using the fixed effects model (FEM) and 2.24 (95% CI 1.15,4.35; P = 0.0003) using the random effects model (REM) (Cochran's Q = 6.83; P = 0.145). The pooled risk difference was 0.11 (95% CI 0.05,0.16; P = 0.0001) by FEM (Cochran's Q = 6.67; P = 0.154) and 0.10 (95% CI 0.04,0.17; P = 0.0023) by REM. There was no significant difference in incidence of adverse effects. Conclusion, Bovine lactoferrin potentially improves H. pylori eradication rates without any impact on adverse effects, but available evidence is limited and further research is necessary to confirm the findings.

    Meta-analysis: the efficacy and safety of certolizumab pegol in Crohn's disease

    ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 6 2009
    L.-M. SHAO
    Summary Background, Certolizumab pegol is the third anti-TNF-, agent approved by the Food and Drug Administration of the United States. Aim, To provide a comprehensive up-to-date review of the efficacy and safety of certolizumab in Crohn's disease (CD). Methods, Electronic databases, including PubMed, EMBASE, the Cochrane library and the Science Citation Index, were searched to retrieve relevant trials. In addition, meeting abstracts and the reference lists of retrieved articles were reviewed for further relevant studies. Results, Three trials, enrolling a total of 1040 patients, are included in the meta-analysis to evaluate the short-term efficacy of certolizumab, which is effective for rapid induction and long-term maintenance of clinical response or remission and can improve quality of life in patients with Crohn's disease. Certolizumab is also effective for patients who have lost response to infliximab. However, its efficacy in infliximab-exposed patients is probably less than in infliximab-naive patients. Re-induction with certolizumab in patients who have flared on maintenance therapy can rescue a significant proportion of patients. There is no significant association between the efficacy of certolizumab and the baseline C-reactive protein level. In comparison with placebo, certolizumab does not increase the risk of serious adverse events. Conclusions, Certolizumab is effective and safe in treating Crohn's disease. Further studies are still required to assess its full safety profile. [source]


    The efficacy of sublingual immunotherapy for house dust mites respiratory allergy: results of a GA˛LEN meta-analysis

    ALLERGY, Issue 11 2009
    E. Compalati
    Recent meta-analyses documented the efficacy and safety of sublingual immunotherapy (SLIT) in patients with allergic rhinitis (AR) and asthma (AA). Although SLIT appeared globally effective, the sub-analyses for single allergens provided uncertain results. This study is aimed to investigate the efficacy of SLIT with house dust mite (HDM) extracts in AR and AA through an updated reassessment of randomized controlled trials. Electronic databases were searched up to March 31, 2008, for randomized DBPC trials, assessing the efficacy of SLIT in AR and AA due to HDM sensitization. Outcomes were symptom scores and rescue medications use. For AR, eight studies fulfilled the selection criteria. A significant reduction in symptoms of AR (SMD ,0.95; CI 95%,1.77 to ,0.14 P = 0.02) was found in 194 patients (adults and children) receiving SLIT compared to 188 receiving placebo. For AA, with nine studies, similar results were found for symptoms (SMD ,0.95; CI 95%,1.74 to ,0.15 P = 0.02) in 243 patients (adults and children) receiving SLIT compared to 209 receiving placebo. A reduction in rescue medication use was found for AR (SMD ,1.88; CI 95%,3.65 to ,0.12 P = 0.04) in 89 patients, and AA (SMD ,1.48; CI 95%,2.70 to ,0.26 P = 0.02) in 202 patients. A relevant inter-study heterogeneity was detected. Promising evidence of efficacy for SLIT, using mite extract in allergic patients suffering from AR and AA, are herein shown. These findings suggest that more data are needed, derived from large-population-based high quality studies, and corroborated by objective outcomes, mainly for AA. [source]

    OBESITY REVIEWS, Issue 3 2001
    A systematic review
    Abstract Background The prevalence of obesity and overweight is increasing worldwide. Obesity in children impacts on their health in both short- and long-term. Obesity prevention strategies are poorly understood. Objective To assess the effectiveness of interventions designed to prevent obesity in childhood. Search strategy Electronic databases were searched from January 1985 to October 1999. Selection criteria Data from randomized control trials and non-randomized trials with concurrent control group were included. A priori, studies with follow up of 1 year minimum were selected however, this was subsequently amended to include studies with a minimum follow up of three months. Data collection & analysis Two reviewers independently extracted data and assessed study quality. Main results Seven studies were included, three long-term (>1 years) and four short-term (>3 months and <1 years). The studies included were diverse in terms of study design and quality, target population, theoretical underpinning of intervention approach, and outcome measures. As such, it was not appropriate to combine study findings using statistical methods. Conclusions Two of the long-term studies (one focused on dietary education and physical activity vs. control, and the other only on dietary education vs. control), resulted in a reduction in the prevalence on obesity, but the third, which focused on dietary education and physical activity, found no effect. Of the four short-term studies, three focused simply on physical activity/reduction of sedentary behavious vs. control. Two of these studies resulted in a reduction in the prevalence of obesity in intervention groups compared with control groups, and another study found a non-significant reduction. The fourth study focused on dietary education and physical activity, and did not find an effect on obesity, but did report a reduction in fat intake. Overall, the findings of the review suggest that currently there is limited quality data on the effectiveness of obesity prevention programmes and as such no generalizable conclusions can be drawn. The need for well-designed studies that examine a range of interventions remains a priority. [source]


    The effect of ranitidine versus proton pump inhibitors on gastric secretions: a meta-analysis of randomised control trials

    ANAESTHESIA, Issue 6 2009
    K. Clark
    Summary Aspiration of acid into the lungs is an infrequent but potentially devastating complication of general anaesthesia. Routine practice often includes use of pharmacological agents to reduce gastric volume and increase gastric pH. The aim of this study was to compare the net benefit of proton pump inhibitors with histamine 2 blockers in a meta-analysis. Electronic databases were searched for trials that compared ranitidine vs proton pump inhibitors in their effect on volume and pH of gastric fluid aspirates. We identified nine trials of which seven were suitable for meta-analysis. Pooled outcomes suggest that premedication with ranitidine is more effective than proton pump inhibitors in reducing the volume of gastric secretions (by an average of 0.22 ml.kg,1; 95% confidence interval 0.04,0.41) and increasing gastric pH (by an average of 0.85 pH units; 95% confidence interval ,1.14 to ,0.28).

    Models for individual oral health promotion and their effectiveness: a systematic review

    AUSTRALIAN DENTAL JOURNAL, Issue 3 2009
    D Yevlahova
    Abstract Background:, There is a recognized need to deliver oral health information to people during clinical encounters to enable them to develop personal skills in managing their own oral health. Traditional approaches to individual oral health education have been shown to be largely ineffective and new approaches are required to address personal motivations for preventive behaviour. This systematic review aims to identify and assess the effectiveness of behaviour models as a basis for individual oral health promotion. Methods:, Electronic databases were searched for articles evaluating the effectiveness of health behaviour models in oral and general health between 2000 and 2007. Eighty-nine studies were retrieved and data were extracted from the 32 studies that met the inclusion criteria. Results:, Thirty-two studies were identified in the fields of clinical prevention and health education, motivational interviewing (MI), counselling, and models based interventions. MI interventions were found to be the most effective method for altering health behaviours in a clinical setting. Conclusions:, There is a need to develop an effective model for chairside oral health promotion that incorporates this evidence and allows oral health professionals to focus more on the underlying social determinants of oral disease during the clinical encounter. There is potential to further develop the MI approach within the oral health field. [source]


    Screening programmes for the early detection and prevention of oral cancer

    AUSTRALIAN DENTAL JOURNAL, Issue 2 2009
    O Kujan
    Background:, Screening programmes for major cancers, such as breast and cervical cancer have effectively decreased the mortality rate and helped to reduce the incidence of these cancers. Although oral cancer is a global health problem with increasing incidence and mortality rates, no national population-based screening programmes for oral cancer have been implemented. To date there is debate on whether to employ screening methods for oral cancer in the daily routine work of health providers. Objectives:, To assess the effectiveness of current screening methods in decreasing oral cancer mortality. Search strategy:, Electronic databases (MEDLINE, CANCERLIT, EMBASE (1966 to July 2005) and CENTRAL (The Cochrane Library 2005, Issue 3), bibliographies, handsearching of specific journals and contact authors were used to identify published and unpublished data. Selection criteria:, Randomized controlled trials of screening for oral cancer or precursor oral lesions using visual examination, toluidine blue, fluorescence imaging or brush biopsy. Data collection and analysis:, The search found 112 citations and these have been reviewed. One randomized controlled trial of screening strategies for oral cancer was identified as meeting the review's inclusion criteria. Validity assessment, data extraction and statistics evaluation were undertaken by two independent review authors. Main results:, One 10-year randomized controlled trial has been included (n = 13 clusters: 191 873 participants). There was no difference in the age-standardized oral cancer mortality rates for the screened group (16.4/100 000 person-years) and the control group (20.7/100 000 person-years). Interestingly, a significant 34% reduction in mortality was recorded in high-risk subjects between the intervention cohort (29.9/100 000 person-years) and the control arm (45.4/100 000). However, this study has some methodological weaknesses. Additionally, the study did not provide any information related to costs, quality of life or even harms of screening from false-positive or false-negative findings. Authors' conclusions:, Given the limitation of evidence (only one included randomized controlled trial) and the potential methodological weakness of the included study, it is valid to say that there is insufficient evidence to support or refute the use of a visual examination as a method of screening for oral cancer using a visual examination in the general population. Furthermore, no robust evidence exists to suggest that other methods of screening, toluidine blue, fluorescence imaging or brush biopsy, are either beneficial or harmful. Future high quality studies to assess the efficacy, effectiveness and costs of screening are required for the best use of public health resources. In addition, studies to elucidate the natural history of oral cancer, prevention methods and the effectiveness of opportunistic screening in high risk groups are needed. Future studies on improved treatment modalities for oral cancer and precancer are also required. Plain language summary:, Screening programmes for the early detection and prevention of oral cancer. More evidence needed to find out whether screening programmes could detect oral cancer earlier and reduce the number of deaths from this disease. Cancer of the mouth and back of the throat (oral cancer) has a low survival rate, largely because the disease is often not diagnosed until it is advanced. Screening the general population for oral cancer might make it possible to detect cases of the disease earlier. The most common method is visual inspection by a clinician, but other techniques include the use of a special blue "dye" and an imaging technique. The review found that there is not enough evidence to decide whether screening by visual inspection reduces the death rate for oral cancer, and no evidence for other screening methods. [source]


    Eliciting Children's and Young People's Views of Child and Adolescent Mental Health Services: A Systematic Review of Best Practice

    CHILD AND ADOLESCENT MENTAL HEALTH, Issue 1 2008
    Anne Worrall-Davies
    Background:, A systematic review of children's and young people's views of Child and Adolescent Mental Health Services (CAMHS) was undertaken to identify the methods used, the ,best practice' methods, and the methods most effective in leading to service changes. Method:, Electronic databases and grey literature were systematically searched. Both authors independently quality-appraised studies using a standard framework. Of 381 studies identified, only 13 were both relevant and of sufficient quality to be included in the review. Interviews, focus groups, brainstorming exercises, and questionnaires were the methods used. Results:, No study reported a change of practice as a result of hearing children's and young people's views. [source]


    Cost-of-illness studies of dementia: a systematic review focusing on stage dependency of costs

    ACTA PSYCHIATRICA SCANDINAVICA, Issue 4 2010
    W. Quentin
    Quentin W, Riedel-Heller SG, Luppa M, Rudolph A, König H-H. Cost-of-illness studies of dementia: a systematic review focusing on stage dependency of costs. Objective:, To review cost-of-illness (COI) studies of dementia from Europe and North America which report costs per patient by disease stage. Method:, A systematic literature search was performed in electronic databases. Studies were classified according to important determinants of costs. Results were converted into year 2006 USD-PPP, and summarized as costs for formal and informal care in mild, moderate and severe dementia. Results:, 28 studies were evaluated. They used a wide range of methods. Costs more than doubled from mild to severe dementia. Patterns and size of estimated costs depended primarily on study objectives (estimation of total costs,net costs), living arrangements of patients (community-dwelling,institutionalized) and inclusion of informal care. Conclusion:, This review is the first to have focused on costs in different stages of dementia. The stage is an important determinant of costs. However, characteristics of individual studies need to be considered, when making use of their results. [source]


    Effects of implementation of psychiatric guidelines on provider performance and patient outcome: systematic review

    ACTA PSYCHIATRICA SCANDINAVICA, Issue 6 2007
    S. Weinmann
    Objective:, To identify evidence from comparative studies on the effects of psychiatric guideline implementation on provider performance and patient outcome. Effects of different implementation strategies were reviewed. Method:, Articles published between 1966 and March 2006 were searched through electronic databases and hand search. A systematic review of comparative studies of structured implementation of specific psychiatric guidelines was performed. Rates of guideline adherence, provider performance data, illness detection and diagnostic accuracy rates were extracted in addition to patient relevant outcome data. Results:, Eighteen studies (nine randomized-controlled trials, six non-randomized-controlled studies and three quasiexperimental before-and-after studies) were identified. Effects on provider performance or patient outcome were moderate and temporary in most cases. Studies with positive outcomes used complex multifaceted interventions or specific psychological methods to implement guidelines. Conclusion:, There is insufficient high-quality evidence to draw firm conclusions on the effects of implementation of specific psychiatric guidelines. [source]


    Relationship of glucose regulation to changes in weight: a systematic review and guide to future research

    DIABETES/METABOLISM: RESEARCH AND REVIEWS, Issue 5 2010
    Ching-Ju Chiu
    Abstract Although weight gain and obesity are risk factors for poor glucose regulation, the relationship, if any, of glucose regulation to changes in weight is not well understood. The purpose of this study was to conduct a systematic review of research examining the relationship of glucose regulation to changes in weight in human-based studies and to provide guidelines for future research in this area. We searched electronic databases and reference sections of relevant articles, including both diabetic and non-diabetic populations, to locate all the literature published before February 2010, and then conducted a systematic review across studies to compare the research designs and findings. The 22 studies meeting our criteria for review generally supported the relationship of glucose regulation to changes in weight. Three studies reported that poor glucose regulation is associated with weight gain; 12 studies concluded that poor glucose regulation is associated with weight loss; 5 showed complex relationships depending on age, sex, or race/ethnicity; and 2 suggested no relationship. The diverse findings may imply that the direction (negative or positive) of the relationship may depend on specific conditions. More research focused on different subpopulations may provide more definitive information supplemental to the current preliminary findings. Recommendations regarding future research in this particular area are provided in the discussion. Copyright © 2010 John Wiley & Sons, Ltd. [source]


    Incorrect and incomplete coding and classification of diabetes: a systematic review

    DIABETIC MEDICINE, Issue 5 2010
    M. A. Stone
    Diabet. Med. 27, 491,497 (2010) Abstract Aims, To conduct a systematic review to identify types and implications of incorrect or incomplete coding or classification within diabetes or between diabetes and other conditions; also to determine the availability of evidence regarding frequency of occurrence. Methods, Medical Subject Headings (MeSH) and free-text terms were used to search relevant electronic databases for papers published to the end of August 2008. Two researchers independently reviewed titles and abstracts and, subsequently, the full text of potential papers. Reference lists of selected papers were also reviewed and authors consulted. Three reviewers independently extracted data. Results, Seventeen eligible studies were identified, including five concerned with distinguishing between Type 1 and Type 2 diabetes. Evidence was also identified regarding: the distinction between diabetes and no-diabetes, failure to specify type of diabetes, and diagnostic errors or difficulties involving maturity-onset diabetes of the young, latent autoimmune diabetes in adults, pancreatic diabetes, persistence of foetal haemoglobin and acquired immune deficiency syndrome (AIDS). The sample was too heterogeneous to derive accurate information about frequency, but our findings suggested that misclassification occurs most commonly in young people. Implications relating to treatment options and risk management were highlighted, in addition to psychological and financial implications and the potential impact on the validity of quality of care evaluations and research. Conclusions, This review draws attention to the occurrence and implications of incorrect or incomplete coding or classification of diabetes, particularly in young people. A pragmatic and clinically relevant approach to classification is needed to assist those involved in making decisions about types of diabetes. [source]


    Diabetic retinopathy screening: a systematic review of the economic evidence

    DIABETIC MEDICINE, Issue 3 2010
    S. Jones
    Diabet. Med. 27, 249,256 (2010) Abstract This paper systematically reviews the published literature on the economic evidence of diabetic retinopathy screening. Twenty-nine electronic databases were searched for studies published between 1998 and 2008. Internet searches were carried out and reference lists of key studies were hand searched for relevant articles. The key search terms used were ,diabetic retinopathy', ,screening', ,economic' and ,cost'. The search identified 416 papers of which 21 fulfilled the inclusion criteria, comprising nine cost-effectiveness studies, one cost analysis, one cost-minimization analysis, four cost,utility analyses and six reviews. Eleven of the included studies used economic modelling techniques and/or computer simulation to assess screening strategies. To date, the economic evaluation literature on diabetic retinopathy screening has focused on four key questions: the overall cost-effectiveness of ophthalmic care; the cost-effectiveness of systematic vs. opportunistic screening; how screening should be organized and delivered; and how often people should be screened. Systematic screening for diabetic retinopathy is cost-effective in terms of sight years preserved compared with no screening. Digital photography with telemedicine links has the potential to deliver cost-effective, accessible screening to rural, remote and hard-to-reach populations. Variation in compliance rates, age of onset of diabetes, glycaemic control and screening sensitivities influence the cost-effectiveness of screening programmes and are important sources of uncertainty in relation to the issue of optimal screening intervals. There is controversy in relation to the economic evidence on optimal screening intervals. Further research is needed to address the issue of optimal screening interval, the opportunities for targeted screening to reflect relative risk and the effect of different screening intervals on attendance or compliance by patients.

    Systematic review of methods to diagnose infection in foot ulcers in diabetes

    DIABETIC MEDICINE, Issue 4 2006
    S. O'Meara
    Abstract Aim, To undertake a systematic review of the diagnostic performance of clinical examination, sample acquisition and sample analysis in infected foot ulcers in diabetes. Methods, Nineteen electronic databases plus other sources were searched. To be included, studies had to fulfil the following criteria: (i) compare a method of clinical assessment, sample collection or sample analysis with a reference standard; (ii) recruit diabetic individuals with foot ulcers; (ii) present 2 × 2 diagnostic data. Studies were critically appraised using a 12-item checklist. Results Three eligible studies were identified, one each on clinical examination, sample collection and sample analysis. For all three, study groups were heterogeneous with respect to wound type and a small proportion of participants had foot ulcers due to diabetes. No studies identified an optimum reference standard. Other methodological problems included non-blind interpretation of tests and the time lag between index and reference tests. Individual signs or symptoms of infection did not prove to be useful tests when assessed against punch biopsy as the reference standard. The wound swab did not perform well when assessed against tissue biopsy. Semiquantitative analysis of wound swab might be a useful alternative to quantitative analysis. The limitations of these findings and their impact on recommendations from relevant clinical guidelines are discussed. Conclusion, Given the importance of this topic, it is surprising that only three eligible studies were identified. It was not possible to describe the optimal methods of diagnosing infection in diabetic patients with foot ulceration from the evidence identified in this systematic review. Diabet.
