Meta-analysis: pre-operative infliximab treatment and short-term post-operative complications in patients with ulcerative colitis

ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 4 2010
Z. YANG
Aliment Pharmacol Ther,31, 486,492 Summary Background, Infliximab was approved for use in ulcerative colitis in recent years. It has been debated if infliximab increases the risk of post-operative complications in patients with ulcerative colitis. Aim, To perform a meta-analysis that examines the relationship between preoperative infliximab treatment and short-term post-operative complications in patients with ulcerative colitis. Methods, We searched the PubMed and MEDLINE databases to identify observational studies on the impact of pre-operative infliximab use on short-term post-operative complications in ulcerative colitis. Infectious complications mainly included wound infection, sepsis and abscess, whereas non-infectious complications included intestinal obstruction, thromboembolism and gastrointestinal haemorrhage. Pooled odds ratios (ORs) were calculated for each relationship. Results, A total of 5 studies and 706 patients were included in our meta-analysis. Overall, we did not find a strong association between pre-operative treatment of infliximab and short-term infectious [OR 2.24, 95% confidence interval (CI) 0.63,7.95] or non-infectious (OR 0.85, 95% CI 0.50,1.45) post-operative complications in ulcerative colitis patients. On the contrary, we discovered that pre-operative infliximab use increased short-term total post-operative complications (OR 1.80, 95% CI 1.12,2.87). Conclusions, Pre-operative infliximab use increased the risk of short-term post-operative complications. Subgroup analysis is underpowered to assess the nature of these complications but shows a trend towards increased post-operative infection. [source]


Systematic review: the short-term and long-term efficacy of adalimumab following discontinuation of infliximab

ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 10 2009
C. MA
Summary Background, Therapy with adalimumab has been shown to be effective in Crohn's disease (CD) patients who have lost response or are intolerant to infliximab. Aim, To determine the efficacy of adalimumab in CD patients who discontinued infliximab through a systematic review. Methods, Electronic searches of EMBASE and MEDLINE databases up to May 1, 2009, as well as abstracts from the AGA (2006,2008), ACG (2006,2007), UEGW (2006,2008) and CDDW (2006,2009) identified randomized-controlled trials (RCT) or open-labelled cohorts (OLC) evaluating the short-term and/or long-term efficacy of adalimumab in infliximab failures. The response rates for short-term (clinical response and remission at 4 weeks) and long-term (remission at 6 and 12 months) efficacy were considered. Results, A total of 1810 CD patients were identified among the 15 studies (2 RCT and 13 OLC). The majority of studies evaluated CD patients who either lost response or were intolerable to infliximab, although five OLCs permitted patients refractory to infliximab. Short-term clinical response (n = 9 articles) ranged from 41% to 83%. Long-term clinical remission at 12 months (n = 8 articles) ranged from 19% to 68%. The occurrence of severe adverse events ranged from 0% to 19% and four patients died. Conclusions, Current RCT and OLC evidence suggest that adalimumab is an efficacious therapy for CD patients who discontinue infliximab. [source]


Mycobacterial infection and atopy in childhood: A systematic review

PEDIATRIC ALLERGY AND IMMUNOLOGY, Issue 7 2007
Charles C. Obihara
The epidemiological relation between mycobacterial infection and the prevalence of atopic disease in humans is still unclear. This is in contrast to studies in murine models in which a clear suppression of atopic symptoms was observed after exposure to mycobacteria or mycobacterial products. We therefore wanted to provide a systematic overview of the published literature on the relationship between mycobacterial infection and atopic disease and to evaluate the causal relationship in a meta-analysis. The EMBASE and MEDLINE databases were searched systematically for papers published in the English literature (1966,2005) on the relation between mycobacterial infection and atopic disease. Original observational or interventional studies involving the paediatric population were included. Two authors independently reviewed articles for data on mycobacterial exposure and atopic disease outcome. Any differences were resolved by discussion. Of a total of 1201 hits, 23 studies (19 cross-sectionals, three case,controls and one prospective cohort) met the inclusion criteria. Only a minority of studies (40%) observed an association between mycobacterial infection and the prevalence of atopic disease outcome. In the meta-analysis, only studies containing data on mycobacterial exposure and atopic disease outcome variables were included. Only cross-sectional studies, in which the relation between a positive tuberculin skin test and allergic symptoms was studied, observed statistically significant negative correlation (odds ratio 0.63; 95% confidence interval: 0.51,0.79). The results of this review show that the evidence of the relationship of mycobacterial infection and atopic disease is based on observations of cross-sectional studies. In a meta-analysis, calculations showed a high level of heterogeneity (I2) within studies with similar design making it difficult to pool effects. This may partly be explained by differences in the type and definition of mycobacterial infection and lack of uniformity in the definition of atopy. The results show that only a minority of studies in the literature shows any evidence of inverse relationship between mycobacterial exposure and atopic disease outcome. The fact that the present epidemiological evidence on the relationship between mycobacterial infection and the development of atopic disease is based mainly on cross-sectional observational studies indicates the need for population-based prospective studies to address this issue. This issue needs to be addressed in view of recent suggestions to developing mycobacterial-based vaccines against atopic disease in the future. [source]


Use of remifentanil as a sedative agent in critically ill adult patients: a meta-analysis

ANAESTHESIA, Issue 12 2009
J. A. Tan
Summary This meta-analysis examined the benefits of using remifentanil as a sedative agent in critically ill patients. A total of 11 randomised controlled trials, comparing remifentanil with another opioid or hypnotic agent in 1067 critically ill adult patients, were identified from the Cochrane controlled trials register and EMBASE and MEDLINE databases, and subjected to meta-analysis. Remifentanil was associated with a reduction in the time to tracheal extubation after cessation of sedation (weighted-mean-difference ,2.04 h (95% CI ,0.39 to ,3.69 h); p = 0.02). Remifentanil was, however, not associated with a significant reduction in mortality (relative risk 1.01 (95% CI 0.67,1.52); p = 0.96), duration of mechanical ventilation, length of intensive care unit stay, and risk of agitation (relative risk 1.08 (95% CI 0.64,1.82); p = 0.77) when compared to an alternative sedative or analgesic agent. The current evidence does not support the routine use of remifentanil as a sedative agent in critically ill adult patients. [source]


Systematic review of high dose chemotherapy and autologous haematopoietic stem cell transplantation for chronic lymphocytic leukaemia: what is the published evidence?

BRITISH JOURNAL OF HAEMATOLOGY, Issue 2 2007
Mohamed A. Kharfan-Dabaja
Summary Despite improved responses, chronic lymphocytic leukaemia (CLL) remains incurable with conventional chemotherapy. Patients with poor-risk factors or who fail conventional chemoimmunotherapy are offered autografts, preferably after achieving remission. This report presents the totality of evidence through a systematic review that assessed the efficacy of autografts in CLL. A search of MEDLINE databases from 1966,2006 and hand-search of references identified 82 prospective-randomized, non-randomized comparisons or single-arm trials, of which only nine met our inclusion criteria: two trials were funded by public/government, one by private foundations, one jointly by private/public, and was unclear in five. No randomized controlled trials comparing autografts versus conventional chemotherapy (or chemoimmunotherapy) were found. Six studies were single-arm and three were non-randomized with a control-arm (autologous versus allogeneic). Overall, 361 patients were enrolled, but only 292 were transplanted. Transplant-related mortality ranged from 0% to 9%. Complete responses ranged from 74% to 100% and molecular responses ranged from 57% to 88%. Overall survival ranged from 68% at 3 years to 58% at 6 years. It is uncertain whether autograft is superior to conventional therapy. The high incidence of myelodysplastic syndrome (9,12%) is particularly concerning in CLL, where median survival is 9 years. [source]


Psychiatric morbidity in patients with Parkinson's disease following bilateral subthalamic deep brain stimulation: literature review

ACTA NEUROPSYCHIATRICA, Issue 4 2008
Linton J. Meagher
Objective:, To provide a comprehensive review and evaluation of the literature pertaining to the psychiatric sequelae of deep brain stimulation (DBS) of the subthalamic nucleus (STN) in patients with Parkinson's disease (PD). Methods:, A structured search of the EMBASE, PsychINFO and MEDLINE databases was performed on articles published since the first use of STN DBS in 1993 for PD until March 2007. Non-human studies were excluded, along with studies reporting on unilateral DBS and studies reporting on the use of STN DBS for indications other than idiopathic PD. Ninety-seven articles were selected for inclusion in the review. Results:, Patients with advanced PD have a high rate of psychiatric morbidity. STN DBS has been shown to be an effective treatment for the control of motor symptoms in advanced PD. Neurobehavioural side-effects are, however, relatively common following STN DBS. Side-effects include impaired executive function and verbal fluency, depression, hypomania, apathy, postoperative delirium, anxiety disorders and psychotic symptoms, especially hallucinations. The alteration in dopaminergic medication following surgery as well as the direct effect of STN stimulation both appear to contribute to the short-term and long-term postoperative psychiatric complications. Methodological issues that limit the applicability of the current literature in this field are highlighted. Conclusions:, STN DBS is an effective treatment for the motor symptoms of advanced PD. However, further research is needed to assess the extent to which STN DBS contributes to or exacerbates psychiatric morbidity over and above that associated with advanced PD. Careful neuropsychiatric evaluation and monitoring are required in this patient group. [source]


Systematic review: impaired drug absorption related to the co-administration of antisecretory therapy

ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 12 2009
E. LAHNER
Summary Background, Due to suppression of gastric acidity during antisecretory therapy, an impaired absorption of co-administered drugs may occur. Aim, To review evidence of impaired drug absorption related to the use of co-administered PPIs or H2RAs. Methods, Systematic search of MEDLINE/EMBASE/SCOPUS databases (1980,September 2008) for English articles with keywords: drug malabsorption and absorption, stomach, anti-secretory/acid inhibitory drugs, histamine H2 antagonists, PPIs, gastric acid, pH, hypochlorhydria, gastric hypoacidity. From 2126 retrieved articles, 16 randomized crossover studies were identified investigating impaired absorption of nine different drugs in association with co-administration of PPIs or H2RAs. Information on investigated drug, study type, features of investigated subjects, study design, type of intervention, and study results were extracted. Results, The identified studies investigated the absorption kinetics of nine drugs. Acid suppression reduced absorption of ketoconazole, itraconazole, atazanavir, cefpodoxime, enoxacin and dipyridamole (median Cmax reduction by 66.5%). An increased absorption of nifedipine and digoxin (median AUC increase by 10%) and a 2-fold-increase in alendronate bioavailability were observed. Conclusions, Gastric pH appears relevant for absorption of some cardiovascular or infectious disease agents. Antisecretory treatment may significantly modify the absorption of co-administered drugs.

Systematic review: Heliocobacter pylori infection and impaired drug absorption

ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 4 2009
E. LAHNER
Summary Background, Impaired acid secretion may affect drug absorption and may be consequent to corporal Heliocobacter pylori- gastritis, which may affect the absorption of orally administered drugs. Aim, To focus on the evidence of impaired drug absorption associated with H. pylori infection. Methods, Data sources were the systematic search of MEDLINE/EMBASE/SCOPUS databases (1980,April 2008) for English articles using the keywords: drug malabsorption/absorption, stomach, Helicobacter pylori, gastritis, gastric acid, gastric pH, hypochlorhydria, gastric hypoacidity. Study selection was made from 2099 retrieved articles, five studies were identified. Data were extracted from selected papers, investigated drugs, study type, main features of subjects, study design, intervention type and results were extracted. Results, In all, five studies investigated impaired absorption of l -dopa, thyroxine and delavirdine in H. pylori infection. Eradication treatment led to 21,54% increase in l -dopa in Parkinon's disease. Thyroxine requirement was higher in hypochlorhydric goitre with H. pylori- gastritis and thyrotropin levels decreased by 94% after treatment. In H. pylori- and HIV-positive hypochlorhydric subjects, delavirdine absorption increased by 57% with orange juice administration and by 150% after eradication. Conclusions, A plausible mechanism of impaired drug absorption is decreased acid secretion in H. pylori -gastritis patients. Helicobacter pylori infection and hypochlorhydria should be considered in prescribing drugs the absorption of which is potentially affected by intragastric pH. [source]


Sensory processing disorder: Any of a nurse practitioner's business?

JOURNAL OF THE AMERICAN ACADEMY OF NURSE PRACTITIONERS, Issue 6 2009
DrNPc, Elise D. Fish Professor of Clinical Health Care for the Underserved, FAAN Stone Foundation, Mary W. Byrne PhD
Abstract Purpose: Children who exhibit the confusing symptom patterns associated with sensory processing deficits are often seen first by primary care providers, including family and pediatric nurse practitioners (NPs). The purpose of this article is to alert NPs to the state of the science for these disorders and to the roles NPs could play in filling the knowledge gaps in assessment, treatment, education, and research. Data sources: Literature searches using PubMed and MedLine databases and clinical practice observations. Conclusions: Sensory integration disorders have only begun to be defined during the past 35 years. They are not currently included in the DSM IV standard terminology, and are not yet substantively incorporated into most health disciplines' curricula or practice, including those of the NP. Implications for practice: NPs are in a unique position to test hypothesized terminology for Sensory Processing Disorder (SPD) by contributing precise clinical descriptions of children who match as well as deviate from the criteria for three proposed diagnostic groups: Sensory Modulation Disorder (SMD), Sensory Discrimination Disorder (SDD), and Sensory-Based Motor Disorder (SBMD). Beyond the SPD diagnostic debate, for children with sensory deficit patterns the NP role can incorporate participating in interdisciplinary treatment plans, refining differential diagnoses, providing frontline referral and support for affected children and their families, and making both secondary prevention and critical causal research possible through validation of consistently accepted diagnostic criteria.

Neuroprotection in emerging psychotic disorders

EARLY INTERVENTION IN PSYCHIATRY, Issue 2 2007
Gregor Berger
Abstract Aim:, The emerging phase of psychotic disorders is pleomorphic and fluctuates in presentation. Hence, from a clinical perspective, treatment modalities are often unclear. This paper investigates the rational and potential use of neuroprotective agents in emerging psychotic disorders. Methods:, Medline databases were searched from 1966 to 2006 followed by the cross-checking of references using following keywords: neuroprotection, apoptosis, natural cell death, neurodevelopment, plasticity, neurogenesis, combined with brain and schizophrenia. Results:, Agents such as atypical antipsychotics, antidepressants, omega-3 fatty acids, modulators of glutamateric neurotransmission (e.g. ampakines, glycine, memantine), erythropoietin, N -acetylcysteine, COX-2 inhibitors or antioxidants have neuroprotective (anti-apoptotic) properties and may therefore be able to protect brain maturational processes disturbed in emerging psychotic disorders. Clinical trials suggest that atypical antipsychotics, antidepressants, omega-3 fatty acids and low-dose lithium as sole treatments were able to improve symptoms and functioning, and delay or in some cases even prevent the onset of frank psychosis. Initially these substances have been chosen because they have been used either as sole or augmentation treatments in established psychotic disorders. However, chronicity and already effective treatments may overshadow their potential clinical use in emerging (prodromal) psychosis. Conclusion:, Neuroprotection as a new treatment paradigm for at-risk mental states seems to be promising and pilot data are suggestive that more benign interventions may already be sufficient to delay or even prevent the onset of frank psychosis. A coordinated research effort will be necessary to address the question which agents should be used under which circumstances. [source]


Outcome of psychological treatments of pathological gambling: a review and meta-analysis

ADDICTION, Issue 10 2005
Ståle Pallesen
ABSTRACT Aims To investigate the short- and long-term effect of psychological treatments of pathological gambling and factors relating to treatment outcome. Design and setting This study provides a quantitative meta-analytical review of psychotherapeutic treatments of pathological gambling. Studies were identified by computer search in the PsycINFO and Medline databases covering the period from 1966 to 2004, as well as from relevant reference lists. Inclusion criteria The target problem was pathological gambling, the treatment was psychological, the study was published in English and outcomes directly pertaining to gambling were employed. Single case studies, studies where elimination of gambling not was the priority and studies with insufficient statistical information were excluded from the present meta-analysis. Participants A total of 37 outcome studies, published or reported between 1968 and 2004, were identified. Of these 15 were excluded, thus 22 studies were included, involving 1434 subjects. The grand mean age was 40.1 years. The overall proportion of men was 71.5%. Measurements The included studies were coded for outcome measures of pathological gambling. For each condition, means and standard deviations for gambling-related outcome measures, all based upon self-reports or therapist ratings, were compiled at three points in time: baseline, post-treatment and the last follow-up reported. Findings Effect sizes represent the difference between the mean score in a treatment condition and a control condition or the difference between mean scores at separated points in time for one group, expressed in terms of standard deviation units. At post-treatment the analysis indicated that psychological treatments were more effective than no treatment, yielding an overall effect size of 2.01 (P < 0.01). At follow-up (averaging 17.0 months) the corresponding effect size was 1.59 (P < 0.01). A multiple regression analysis showed that the magnitude of effect sizes at post-treatment were lower in studies including patients with a formal diagnosis of pathological gambling only, compared to studies not employing such inclusion criteria. Effect sizes were also higher in randomized controlled trials compared to not randomized controlled trials, higher in within subjects designs compared to between subjects designs and also positively related to number of therapy sessions. No mediator variables were significantly related to the magnitude of the effect sizes at follow-up. Conclusion Psychological interventions for pathological gamble seem to be yield very favourable short- and long-term outcomes. [source]


Maternal distress: a concept analysis

JOURNAL OF ADVANCED NURSING, Issue 9 2010
Elizabeth Emmanuel
emmanuel e. & st john w. (2010) Maternal distress: concept analysis. Journal of Advanced Nursing,66(9), 2104,2115. Abstract Aim., This paper is a report of an analysis of the concept of maternal distress. Background., Although not well-developed, the concept of maternal distress has offered an important viewpoint in nursing and midwifery practice since the mid-1990s. Traditionally, understanding of maternal distress has been based on the medical model and dysfunction. The concept of maternal distress needs development so that it describes responses ranging from normal stress responses to those indicating mental health problem/s. Data sources., The SCOPUS, CINAHL and Medline databases were searched for the period from 1995 to 2009 using the keywords ,psychological distress', ,emotional distress' and ,maternal distress'. Review methods., Steps from Rodgers' evolutionary concept analysis guided the conduct of this concept analysis. Results., Four attributes of maternal distress were identified as responses to the transition to motherhood, with the level of each response occurring along a continuum: stress, adapting, functioning and control, and connecting. Antecedents to maternal distress include becoming a mother, role changes, body changes and functioning, increased demands and challenges, losses and gains, birth experiences, and changes to relationships and social context. The consequences of maternal distress are compromised mental health status, maternal role development, quality of life, ability to function, quality of relationships and social engagement. The extent of the impact depends on the level of maternal distress. Conclusion., Clearer interpretation of maternal distress offers a comprehensive approach to understanding maternal emotional health during the transition to motherhood. Acknowledging women's experiences and providing more appropriate support could alleviate some of the struggles and hardships experienced by mothers. [source]


A systematic review of the effectiveness of cutaneous warming systems to prevent hypothermia

JOURNAL OF CLINICAL NURSING, Issue 5 2009
Cristina M Galvão
Aims., To retrieve and critique recent randomised trials of cutaneous warming systems used to prevent hypothermia in surgical patients during the intraoperative period and to identify gaps in current evidence and make recommendations for future trials. Background., Hypothermia affects up to 70% of anaesthetised surgical patients and is associated with several significant negative health outcomes. Design., Systematic review using integrative methods. Methods., We searched CINAHL, EMBASE, Cochrane Register of Controlled Trials and Medline databases (January 2000,April 2007) for recent reports on randomised controlled trials of cutaneous warming systems used with elective patients during the intraoperative period. Inclusion criteria., We included randomised control trials examining the effects of cutaneous warming systems used intraoperatively on patients aged 18 years or older undergoing non-emergency surgery. Studies published in English, Spanish or Portuguese with a comparison group that consisted of either usual care or active cutaneous warming systems without prewarming were reviewed. Results., Of 193 papers initially identified, 14 studies met the inclusion criteria. There was moderate evidence to indicate that carbon-fibre blankets and forced-air warming systems are equally effective and that circulating-water garments are most effective for maintaining normothermia during the intraoperative period. Few trials reported costs. Conclusions., Carbon-fibre blankets and forced-air warming systems are effective and circulating-water garments may be preferable. Future research should measure the direct and indirect costs associated with competing systems. Relevance to clinical practice., Nurses can use this review to inform their selection of warming interventions in perioperative nursing practice. They can also assess other factors such as nursing workload, staff training and equipment maintenance, which should be incorporated into future research. [source]


Relatives in end-of-life care , part 1: a systematic review of the literature the five last years, January 1999,February 2004

JOURNAL OF CLINICAL NURSING, Issue 9 2006
Birgitta Andershed PhD
Aim., To review systematically research conducted during the past five years focusing on the relatives' situation and needs in end-of-life care. Background and aim., That relatives make a large contribution in the care of the dying is well-known. In this situation, relatives often have to solve many new practical problems in the care as well as dealing with the sorrow of both themselves and the dying person. In recent years, palliative care has been developed in many countries and many new studies have been carried out. Methods., A systematic search of the literature was performed in the CINAHL and Medline databases. Of the 94 papers analysed, there were 59 qualitative and 35 quantitative studies with differing designs. The studies were carried out in 11 countries and were published in 34 different journals. Results., The results were categorized in two main themes with several subthemes: (1) being a close relative , the situation: (i) exposed position , new responsibility, (ii) balance between burden and capacity and (iii) positive values; (2) being a close relative , needs: (i) good patient care, (ii) being present, (iii) knowing and communicating and (iv) support from and trusting relationship with the professional. The relative's feelings of security and trust in the professional were found to be of great importance. Conclusion., More than twice as many studies had a descriptive/explorative design, which is of importance in the assessment of evidence. However, different studies complement one another and in summary, it can be said that analytic evidence is unequivocal: good patient care, communication, information and the attitude of the professional are of decisive importance regarding relatives' situation. These results are also in accord with earlier review studies. Relevance to clinical practice., Staff members have a great deal of responsibility for assuring that the patient feels as good as possible, facilitating relatives' involvement based on the family's wishes and limiting the stress and difficulties experienced by the family. The results showed that the relative's satisfaction could depend on the attitude of the professional as well as on good communication, good listening and good information. This can also be viewed as a prerequisite for the professional to get to know the family and to provide ,care in the light'. [source]


Modifying Women's Risk for Cardiovascular Disease

JOURNAL OF OBSTETRIC, GYNECOLOGIC & NEONATAL NURSING, Issue 2 2007
Kathleen M. McCauley
Objective:, To present current recommendations for cardiovascular disease risk reduction in women. Data Sources:, Medline databases were searched from 1990 to 2006 using keywords women and cardiovascular risk, hypertension, cholesterol, and hormone replacement therapy, as well as Web sites from scientific associations such as the American Heart Association, American College of Cardiology, Agency for Health Research and Quality, and the Centers for Disease Control for relevant scientific statements and guidelines. Study Selection:, Randomized controlled trials, particularly those that have influenced current practice recommendations, scientific statements, and clinical practice guidelines were selected. Data Extraction and Synthesis:, Factors contributing to women's particular risk and current practice recommendations. Conclusions:, Current research has clarified the importance of regular exercise (at least 30 minutes/day most days of the week); abstinence from smoking; a diet focused on whole grains, fruits, vegetables, and low-fat protein sources; and maintenance of normal weight. This lifestyle combined with a partnership with a health care provider to maintain a normal blood pressure (115/75 mm Hg) and optimal lipoproteins through pharmacotherapy when indicated can prevent 82% of cardiovascular disease events in women.

School-Based Obesity Interventions: A Literature Review

JOURNAL OF SCHOOL HEALTH, Issue 4 2008
Fadia T. Shaya PhD
ABSTRACT Background:, Childhood obesity is an impending epidemic. This article is an overview of different interventions conducted in school settings so as to guide efforts for an effective management of obesity in children, thus minimizing the risk of adult obesity and related cardiovascular risk. Methods:, PubMed and OVID Medline databases were searched for school-based obesity interventions with anthropometric measures in children and adolescents between the ages of 7 and 19 years from June 1986 to June 2006. Studies were reviewed by duration, type of intervention, and defined qualitative and quantitative measures, resulting in a yield of 51 intervention studies. Results:, The interventions ranged from 4 weeks in length to as long as 8 continuing years. In total, 15 of the intervention studies exclusively utilized physical activity programs, 16 studies exclusively utilized educational models and behavior modification strategies, and 20 studies utilized both. In addition, 31 studies utilized exclusively quantitative variables like body mass indices and waist-to-hip ratios to measure the efficacy of the intervention programs, and another 20 studies utilized a combination of quantitative and qualitative measures that included self-reported physical activity and attitude toward physical activity and the tested knowledge of nutrition, cardiovascular health, and physical fitness. A total of 40 studies achieved positive statistically significant results between the baseline and the follow-up quantitative measurements. Conclusions:, No persistence of positive results in reducing obesity in school-age children has been observed. Studies employing long-term follow-up of quantitative and qualitative measurements of short-term interventions in particular are warranted. [source]


Systematic review: fatigue in inflammatory bowel disease

ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 2 2010
D. R. Van Langenberg
Aliment Pharmacol Ther 2010; 32: 131,143 Summary Background, Fatigue is common, disabling yet underappreciated, in patients with chronic diseases, including inflammatory bowel disease (IBD). Aims, To examine the literature and determine the prevalence and patterns of fatigue in IBD patients, to identify opportunities and directions for future research in this area. Methods, A systematic review using PubMed and Ovid Medline databases was conducted using search terms ,fatigue', ,Crohn', ,colitis' and ,inflammatory bowel disease'. A review of fatigue in other similar chronic diseases was also performed. Results, Ten studies were found to include data on fatigue in IBD patients; all were conducted between 1999 and 2009. However, only one study (in children) measured fatigue in IBD patients as a primary outcome. In patients in remission, the prevalence of fatigue in IBD patients ranges from 41 to 48%. Data are sparse and conflicting on whether fatigue severity is proportional to disease severity/activity. Conclusions, Despite the clinical reality of fatigue, there are few published studies examining fatigue in IBD as a primary outcome. More data are needed on the prevalence, correlation between disease activity and fatigue severity, and putative pathogenic pathways involved in fatigue pathogenesis, before ultimately elucidating targeted therapies for fatigue in IBD patients.

Review article: yeast as probiotics ,Saccharomyces boulardii

ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 6 2007
D. CZERUCKA
Summary Background Probiotics are defined as live micro-organisms which confer a health benefit on the host. Although most probiotics are bacteria, one strain of yeast, Saccharomyces boulardii, has been found to be an effective probiotic in double-blind clinical studies. Aims To compare the main properties that differentiates yeast from bacteria and to review the properties of S. boulardii explaining its potential benefits as a probiotic. Methods The PubMed and Medline databases were searched using the keywords ,probiotics', ,yeast', ,antibiotic associated diarrhea', ,Saccharomyces boulardii',,bacterial diarrhea' and ,inflammatory bowel disease' in various combinations. Results Several clinical studies have been conducted with S. boulardii in the treatment and prevention of various forms of diarrhoea. Promising research perspectives have been opened in terms of maintenance treatment of inflammatory bowel diseases. The mechanism of S. boulardii's action has been partially elucidated. Conclusion Saccharomyces boulardii is a strain of yeast which has been extensively studied for its probiotic effects. The clinical activity of S. boulardii is especially relevant to antibiotic-associated diarrhoea and recurrent Clostridium difficile intestinal infections. Experimental studies clearly demonstrate that S. boulardii has specific probiotic properties, and recent data has opened the door for new therapeutic uses of this yeast as an ,immunobiotic'.

Review article: smoking cessation as primary therapy to modify the course of Crohn's disease

ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 8 2005
G. J. Johnson
Summary This article aims to offer an updated review of the effects of smoking on inflammatory bowel disease, and provide a review of the methods of achieving smoking cessation. A systematic review of Embase and Medline databases was conducted. Smoking causes opposing effects on ulcerative colitis and Crohn's disease. The odds ratio of developing ulcerative colitis for smokers compared with lifetime non-smokers is 0.41. Conversely, smokers with Crohn's disease have a more aggressive disease requiring more therapeutic intervention. Smoking cessation is associated with a 65% reduction in the risk of a relapse as compared with continued smokers, a similar magnitude to that obtained with immunosuppressive therapy. Although difficult to achieve smoking cessation can best be encouraged by accessing appropriate counselling services, nicotine replacement therapy and bupropion. Using a combination of these treatments there is an improved chance of success of up to 20% compared with an unassisted quit attempt. Smoking cessation unequivocally improves the course of Crohn's disease and should be a primary therapeutic aim in smokers with Crohn's disease. [source]


Key words and their role in information retrieval

HEALTH INFORMATION & LIBRARIES JOURNAL, Issue 3 2010
Maria J. Grant
As any good library or information worker knows the accurate and consistent application of keywords can serve to enhance the content representation and retrieval of literature. Research has demonstrated that this aspect of the library and information science evidence base is particularly well represented. Drawing on the thesauri of the Library & Science Abstracts, Library, Information Science & Technology Abstracts and medline databases, the Health Information and Libraries Journal (HILJ) has recently updated and expanded the HILJ keyword list. Based on the content of reviews and original articles published in HILJ over the past 4 years, the keyword list will be used by submitting authors to represent the content of the manuscripts and enable more accurate matching of manuscript to HILJ referees.
