Selected AbstractsA Review of the Effect of the Psychosocial Working Environment on Physiological Changes in Blood and UrineBASIC AND CLINICAL PHARMACOLOGY & TOXICOLOGY, Issue 2 2009Åse M. Hansen Literature databases (PubMed, Toxline, Biosis and Embase) were screened using the key words job, work-related and stress in combination with selected physiological parameters. In total, 51 work place studies investigated the associations between the psychosocial working environment and physiological changes, of which 20 were longitudinal studies and 12 population-based studies. The studied exposures in work place/population-based studies included: job demands (26/8 studies), job control (24/10 studies), social support and/or leadership behaviour (12/3 studies), effort,reward imbalance (three/one studies), occupational changes (four studies), shift work (eight studies), traumatic events (one study) and other (five studies). The physiological responses were catecholamines (adrenaline, noradrenaline) (14 studies), cortisol (28 studies), cholesterol (23 studies), glycated haemoglobinA1c (six studies), testosterone (nine studies), oestrogens (three studies), dehydroepiandrosterone (six studies), prolactin (14 studies), melatonin (one study), thyroxin (one study), immunoglobulin (Ig) A (five studies), IgG (four studies), IgM (one study) and fibrinogen (eight studies). In general, fibrinogen and catabolic indicators, defined as energy releasing, were increased, whereas the anabolic indicators defined as constructive building up energy resources were decreased when the psychosocial working environment was perceived as poor. In conclusion, in this review the association between an adverse psychosocial working environment and HbA1c, testosterone and fibrinogen in serum was found to be a robust and potential candidate for a physiological effect of the psychosocial working environment. Further, urinary catecholamines appear to reflect the effects of shift work and monotonous work. [source] Comparison of the effects of treatment of peri-implant infection in animal and human studies: systematic review and meta-analysisCLINICAL ORAL IMPLANTS RESEARCH, Issue 2 2010Clovis Mariano Faggion Jr Abstract Objective: The main objective of this systematic review is to compare the effects of treatment of peri-implant infection between animal and human studies. Material and methods: A literature search was conducted using the Medline, Cochrane Central Register of Controlled Trials, and Latin American and Caribbean Health Sciences Literature databases up to and including May 2008. In addition, bibliographies of systematic reviews on peri-implant diseases were searched manually. Non-surgical and surgical treatments of peri-implantitis/mucositis in animal models or human studies were compared. Meta-analysis was conducted to investigate the difference between the reported treatment effects in animal and human studies. Changes in probing pocket depth (PPD) and probing attachment level (PAL) from baseline measurements were used as measures of outcome. Single-level and multilevel meta-regression analysis was performed by taking into account the different follow-up times of the studies included. Results: The single-level and multilevel random-effects meta-analysis showed that the difference in PPD reduction [0.31 mm, 95% confidence interval (CI): ,0.27, 0.88] and in PAL gain (0.21 mm, 95% CI: ,0.47, 0.88) between animal and human studies was not statistically significant. The random-effects meta-regression suggested that studies with longer follow-up times revealed greater PPD reduction (0.25 mm per month, 95% CI: 0.14, 0.35). However, when the different follow-up times were taken into account, these differences became greater. Substantial heterogeneity between studies was found in the meta-analyses (I2=97.6% for animal studies and 99.9% for human studies). Conclusion: There was great heterogeneity between human and animal studies in terms of study designs and treatment procedures. Therefore, the results from this meta-analysis should be interpreted with caution. Heterogeneity between studies and its causes merit further investigations.

J. Mari Mari JJ, Patel V, Kieling C, Razzouk D, Tyrer P, Herrman H. The 5/95 gap in the indexation of psychiatric journals of low- and middle-income countries. Objective:, To investigate the relationship between science production and the indexation level of low- and middle-income countries (LAMIC) journals in international databases. Method:, Indicators of productivity in research were based on the number of articles produced over the 1994,2004 period. A survey in both Medline and ISI/Thomson was conducted to identify journals according to their country of origin. A WPA Task Force designed a collaborative process to assess distribution and quality of non-indexed LAMIC journals. Results:, Twenty LAMIC were found to present more than 100 publications and a total of 222 indexed psychiatric journals were found, but only nine were from LAMIC. The Task Force received 26 questionnaires from editors of non-indexed journals, and concluded that five journals would meet criteria for indexation. Conclusion:, Barriers to indexation of journals contribute to the difficulties in achieving fair representation in the main literature databases for the scientific production in these countries. [source] Prevalence of alcohol use disorders in schizophrenia , a systematic review and meta-analysisACTA PSYCHIATRICA SCANDINAVICA, Issue 2 2009J. Koskinen Objective:, Our aim was to present recent studies of alcohol use disorders (AUDs) in patients with schizophrenia, estimate overall prevalence and characteristics affecting the prevalence of AUDs. Method:, We conducted a search using three literature databases and a manual search on articles published in 1996,2008. Meta-regression was used to study how prevalence is affected by different study characteristics. Articles that reported diagnoses according to DSM or ICD diagnostic systems were included. Results:, Altogether 60 studies met our criteria. The median of current AUD prevalence was 9.4% (inter-quartile range, IQR 4.6,19.0, 18 studies) and median of lifetime AUD prevalence 20.6% (IQR 12.0,34.5, 47 studies). In studies using DSM-III-R median prevalence was higher than that in studies using DSM-IV, ICD-9 or ICD-10 (32/17/11/6%). Conclusion:, Approximately every fifth patient with schizophrenia had lifetime AUD diagnosis. When contrasted with the most recent review, there might be a descending trend in AUD prevalence in patients with schizophrenia. [source] Information and communication technology among undergraduate dental students in FinlandEUROPEAN JOURNAL OF DENTAL EDUCATION, Issue 4 2002Jorma I. Virtanen Use of information and communication technology (ICT) is rapidly increasing in medical and dental education. The aim of the present study was to determine the knowledge, skills and opinions of dental undergraduate students regarding ICT and to analyze possible shifts in the acquisition of these resources. For these purposes a survey of all undergraduate dental students at the University of Oulu, Finland, was conducted during the spring term 2000. All the students in the 5 years of study (n = 140) were asked to answer a questionnaire presented during a lecture or demonstration. An overall response rate of 95% was achieved. The frequencies and percentage distributions of the items were analyzed separately for each year (1,5). All the students in the faculty are provided with personal e-mail addresses at the beginning of their studies and special emphasis has been laid on the utilization of their ICT knowledge and skills. An overwhelming majority of the students, more than 95%, judged themselves to have good or satisfactory skills in word processing, but only a slight majority considered that they could manage some advanced operating system functions. Use of ICT services was high, as about 60% of the students used e-mail and one-third WWW services daily. Literature retrieval was widely employed, so that almost 80% of the students had used literature databases (including Ovid Medline and collections of electronic full-text articles), which were introduced and provided by the Medical Library when the students were in their second year. More than 50% had received educational material in electronic form often or sometimes, and almost 80% had communicated by e-mail with a faculty teacher. A clear trend (P < 0.05) was found for the younger students to use ICT services in general and for educational purposes more often than the older ones. In conclusion, e-mail and WWW have been widely adopted for both private and educational purposes by dental students in Finland and are employed together with WWW-based medical and dental publication databases. The younger students have more interest in ICT and better skills, which presents a challenge for dental education in the future. [source] Gatekeepers in sickness insurance: a systematic review of the literature on practices of social insurance officersHEALTH & SOCIAL CARE IN THE COMMUNITY, Issue 3 2005Elsy Söderberg Abstract Decisions concerning entitlement to sickness benefits have a substantial impact on the lives of individuals and on society. In most countries, such decisions are made by staff of private or public insurance organisations. The work performed by these professionals is debated, hence more knowledge is needed on this subject. The aim of the present study was to review scientific studies of the practices of social insurance officers (SIOs) published in English, Danish, Norwegian and Swedish. Studies were searched for in literature databases, in reference lists, and through personal contacts. Analyses were made of type of study, areas investigated, research questions, theories used, and the results. Sixteen studies were included. SIOs and several other actors are responsible for applying measures to minimise sick-leave and promote return to work (RTW). The studies focusing on coordination of such measures revealed that SIOs felt unsure about how to handle their contacts with clients and other actors. One study indicated that the SIOs, partly due to lack of time, accepted the recommendations of physicians instead of making their own judgments about granting sickness benefits. While all SIOs must make decisions concerning entitlement to sickness benefits on a daily basis, few of the reviewed studies scrutinised the actual granting of sickness compensation. The studies were also deficient in that they investigated the decision latitude of the SIOs from a very limited perspective, mainly on an individual level and often primarily in relation to colleagues and/or clients rather than to the laws and regulations of the sickness insurance. The concepts and framework in this area of research need to be developed to facilitate elucidation of the interaction between different actors in local spheres, professionals in different disciplines, and between welfare staff and individual citizens. [source] Measurement of post-operative cognitive dysfunction after cardiac surgery: a systematic reviewACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 6 2010J. L. RUDOLPH Post-operative cognitive dysfunction (POCD) is a decline in cognitive function from pre-operative levels, which has been frequently described after cardiac surgery. The purpose of this study was to examine the variability in the measurement and definitions for POCD using the framework of a 1995 Consensus Statement on measurement of POCD. Electronic medical literature databases were searched for the intersection of the search terms ,thoracic surgery' and ,cognition, dementia, and neuropsychological test.' Abstracts were reviewed independently by two reviewers. English articles with >50 participants published since 1995 that performed pre-operative and post-operative psychometric testing in patients undergoing cardiac surgery were reviewed. Data relevant to the measurement and definition of POCD were abstracted and compared with the recommendations of the Consensus Statement. Sixty-two studies of POCD in patients undergoing cardiac surgery were identified. Of these studies, the recommended neuropsychological tests were carried out in less than half of the studies. The cognitive domains measured most frequently were attention (n=56; 93%) and memory (n=57; 95%); motor skills were measured less frequently (n=36; 60%). Additionally, less than half of the studies examined anxiety and depression, performed neurological exam, or accounted for learning. Four definitions of POCD emerged: per cent decline (n=15), standard deviation decline (n=14), factor analysis (n=13), and analysis of performance on individual tests (n=12). There is marked variability in the measurement and definition of POCD. This heterogeneity may impede progress by reducing the ability to compare studies on the causes and treatment of POCD. [source] Breast cancer risk factors in Korean women: a literature reviewINTERNATIONAL NURSING REVIEW, Issue 3 2008S.-M. Lee rn Aim:, To compile a complete list of risk factors from the Korean breast cancer studies to obtain relevant predictor information essential in developing a predictive model for breast cancer. Background:, Breast cancer is the most commonly diagnosed female cancer in Korea. However, the breast cancer-screening rate in Korea is relatively low compared with that in other countries. In order to promote early health screening, there is a need to identify those individuals who are most likely to develop breast cancer by using an accurate predictive model. Methods:, Thirty-four breast cancer studies were selected from MEDLINE and two Korean literature databases. Two researchers summarized the risk factors and their effects in each article using a checklist. Findings:, Most of the studies were case,control studies conducted after 2000. In 34 articles, a total of 84 risk factors for breast cancer in Korean women were identified; of these, 58 factors were determined as statistically significant factors. The factors identified most often were body mass index, menarche, menopause, family history, pregnancy and delivery, breastfeeding, alcohol use, smoking habits, diet, education and use of oral contraceptives. None of 34 studies looked at stress as a risk factor of which influence on cancer has been reported in other populations. Conclusion:, The next steps will be to construct a questionnaire consisting of relevant variables based on these study results and to develop a predictive model. This would be used to encourage those Koreans who are more likely to develop breast cancer to have early check-ups. [source] Knowledge and use of evidence-based nutrition: a survey of paediatric dietitiansJOURNAL OF HUMAN NUTRITION & DIETETICS, Issue 5 2003D. E. Thomas Abstract Objective To survey paediatric dietitians' knowledge and use of evidence-based nutrition (EBN). Design Cross-sectional survey using reply-paid questionnaires. Subjects Paediatric dietitians in Australian teaching hospitals. Main outcome measures Age, sex, appointment, clinical practice, research activities; attitudes to, training in and use of EBN; and perceived barriers to use of EBN. Statistical analysis Data were analysed using descriptive statistics (SPSS). Results Fifty-nine (86%) of 69 questionnaires were returned. Most (97%) dietitians were women working full-time (63%), mean age 37 years (±9 SD). Most (75%) dietitians encountered knowledge gaps less than five times per week and most (87%) questions related to therapy. The majority (95%) performed their own literature searches, less than five times per month. All had access to ,1 electronic literature databases including Medline (n = 58, 98%), Cochrane Library (n = 44, 75%) and CINAHL (n = 35, 59%). Information sources used most often were Medline and consultation with colleagues. Reported barriers to using EBN were lack of time (n = 53, 90%) or lack of skills for critical appraisal of published articles (n = 51, 86%) or literature searching (n = 48, 81%). While 53 (90%) believed in an evidence-based approach, 43 (73%) either did not practise EBN or rated themselves as beginners. Conclusion Most dietitians favoured evidence-based practice, but reported lack of time, skills or rapid access to electronic databases as barriers to its practice. [source] Critical care nurse practitioners and clinical nurse specialists interface patterns with computer-based decision support systemsJOURNAL OF THE AMERICAN ACADEMY OF NURSE PRACTITIONERS, Issue 11 2007APRN (Assistant Professor of Health, Community Systems, Coordinator of the Nursing Education Graduate Program), PhD(c), Scott Weber EdD Abstract Purpose: The purposes of this review are to examine the types of clinical decision support systems in use and to identify patterns of how critical care advanced practice nurses (APNs) have integrated these systems into their nursing care patient management practices. The decision-making process itself is analyzed with a focus on how automated systems attempt to capture and reflect human decisional processes in critical care nursing, including how systems actually organize and process information to create outcome estimations based on patient clinical indicators and prognosis logarithms. Characteristics of APN clinicians and implications of these characteristics on decision system use, based on the body of decision system user research, are introduced. Data sources: A review of the Medline, Ovid, CINAHL, and PubMed literature databases was conducted using "clinical decision support systems,""computerized clinical decision making," and "APNs"; an examination of components of several major clinical decision systems was also undertaken. Conclusions: Use patterns among APNs and other clinicians appear to vary; there is a need for original research to examine how APNs actually use these systems in their practices in critical care settings. Because APNs are increasingly responsible for admission to, and transfer from, critical care settings, more understanding is needed on how they interact with this technology and how they see automated decision systems impacting their practices. Implications for practice: APNs who practice in critical care settings vary significantly in how they use the clinical decision systems that are in operation in their practice settings. These APNs must have an understanding of their use patterns with these systems and should critically assess whether their patient care decision making is affected by the technology. [source] Psychosocial interventions and quality of life in gynaecological cancer patients: a systematic reviewPSYCHO-ONCOLOGY, Issue 8 2009Jolyn Hersch Abstract Objective: Women with gynaecological cancer are at risk of poor quality of life outcomes. Although various psychosocial interventions have been developed to address these concerns, such interventions have not yet been systematically evaluated in this population. The current review provides an up-to-date and comprehensive summary of the evidence regarding the effectiveness of psychosocial interventions in women with gynaecological cancers. Methods: Relevant studies were identified via Medline, CINAHL, and PsycINFO databases (1980 to June 2008), reference lists of articles and reviews, grey literature databases, and consultations with physicians and other experts in the field. Only controlled trials comparing a psychosocial intervention with a control group in a gynaecological cancer population, with at least one quality of life variable as a main outcome, were included in the review. Two authors independently assessed trial quality and extracted data. Results: Twenty-two studies involving 1926 participants were included. There was substantial variability in study quality and results. Evidence was mixed regarding intervention effects on social and sexual functioning, distress, depression, anxiety, attitude to medical care, self-esteem and body image. Interventions generally did not improve physical or vocational outcomes. Conclusions: There was limited evidence in support of healing touch, whereas information-based interventions seemed largely unable to provide meaningful benefits. Cognitive-behavioural interventions had some positive effects. Counselling appeared to be the most promising intervention strategy for addressing quality of life concerns for women with gynaecological cancers. Copyright © 2008 John Wiley & Sons, Ltd. [source] Psychosocial issues in genetic testing for familial adenomatous polyposis: a review of the literaturePSYCHO-ONCOLOGY, Issue 8 2008K. F. L. Douma Abstract Objectives: Familial adenomatous polyposis (FAP) is characterized by the development of multiple adenomas in the colon that can lead to colorectal cancer. Being a carrier for FAP is hypothesized to have a negative impact on psychosocial well-being. This paper reviews the current literature on the psychosocial aspects of FAP. Methods: Four literature databases were used to identify all papers published between 1986 and 2007 about psychosocial and behavioral issues in FAP related to genetic testing. The following topics were reviewed: uptake and psychosocial impact of genetic testing, endoscopic screening behavior and psychosocial well-being in general. Results: Seventeen papers were identified. Across studies, genetic test uptake varied between 62 and 97%. Two out of three studies showed clinical levels of anxiety and/or depression after genetic testing. A minority of individuals were not reassured by a negative test result, and intended to continue endoscopic surveillance. Well-being (e.g. quality of life, family functioning) was found to be lower in some studies, while comparable to the general population in other studies. The studies had several shortcomings, such as mixed patient population (e.g. colorectal and breast cancer) and small sample sizes, and provided no information on other potentially important issues, such as psychosexual development. Conclusions: Future studies should employ larger sample sizes and standardized measurements. Additionally, future studies should address the long-term consequences of genetic testing for FAP, psychosexual development and consequences of FAP for the family as a whole.
