Background The safety and effectiveness of CAM interventions are of great relevance to pediatric health care providers. The objective of this study is to identify sources of reported randomized controlled trials (RCTs) in the field of pediatric complementary and alternative medicine (CAM). Methods Reports of RCTs were identified by searching Medline and 12 additional bibliographic databases and by reviewing the reference lists of previously identified pediatric CAM systematic reviews. Results We identified 908 reports of RCTs that included children under 18 and investigated a CAM therapy. Since 1965, there has been a steady growth in the number of these trials that are being published. The four journals that published the most reported RCTs are The American Journal of Clinical Nutrition, Pediatrics, Journal of Pediatrics, and Lancet. Medline, CAB Health, and Embase were the best database sources for identifying these studies; they indexed 93.2%, 58.4% and 42.2 % respectively of the journals publishing reports of pediatric CAM RCTs. Conclusions Those working or interested in the field of pediatric CAM should routinely search Medline, CAB Health and Embase for literature in the field. The four core journals identified above should be included in their collection. PMID:12589711

Research has indicated that adverse effects terms are increasingly prevalent in the title, abstract or indexing terms of articles that contain adverse drug effects data in MEDLINE and Embase. However, it is unknown whether adverse effects terms are present in the database records of articles that contain adverse effects data of medical devices, and thus, to what extent the development of an adverse effects search filter for medical devices may be feasible. A case study systematic review of a medical device was selected. The included studies from a systematic review of the safety of recombinant human bone morphogenetic protein-2 (rhBMP-2) for spinal fusion were used in the analysis. For each included study, the corresponding database record on MEDLINE and Embase was assessed to measure the presence or absence of adverse effects terms in the title, abstract or indexing. The performance of each potential adverse effects search term was also measured and compared. There were 82 publications (49 studies) included in the systematic review with 51 of these indexed on MEDLINE and 55 on Embase. Ninety-four percent (48/51) of the records on MEDLINE and 95% (52/55) of the records on Embase contained at least one adverse effects related search term. The wide variety of adverse effects terms included in the title, abstract or indexing of bibliographic records, and the lack of any individual high-performing search terms suggests that a combination of terms in different fields is required to identify adverse effects of medical devices. In addition, the most successful search terms differed from the most successful terms for identifying adverse drug effects. The search filters currently available for adverse drug effects are not necessarily useful for searching adverse effects data of medical devices. The presence of adverse effects terms in the bibliographic records of articles on medical devices, however, indicates that combinations of adverse effects search terms may be useful in search strategies in MEDLINE and Embase. The results, therefore, suggest that not only a search filter for the adverse effects of medical devices is feasible, but also that it should be a research priority.

Bibliographic databases are the primary resource for identifying systematic reviews of health care interventions. Reliable retrieval of systematic reviews depends on the scope of indexing used by database providers. Therefore, searching one database may be insufficient, but it is unclear how many need to be searched. We sought to evaluate the performance of seven major bibliographic databases for the identification of systematic reviews for hypertension. We searched seven databases (Cochrane library, Database of Abstracts of Reviews of Effects (DARE), Excerpta Medica Database (EMBASE), Epistemonikos, Medical Literature Analysis and Retrieval System Online (MEDLINE), PubMed Health and Turning Research Into Practice (TRIP)) from 2003 to 2015 for systematic reviews of any intervention for hypertension. Citations retrieved were screened for relevance, coded and checked for screening consistency using a fuzzy text matching query. The performance of each database was assessed by calculating its sensitivity, precision, the number of missed reviews and the number of unique records retrieved. Four hundred systematic reviews were identified for inclusion from 11,381 citations retrieved from seven databases. No single database identified all the retrieved systematic reviews for hypertension. EMBASE identified the most reviews (sensitivity 69 %) but also retrieved the most irrelevant citations with 7.2 % precision (Pr). The sensitivity of the Cochrane library was 60 %, DARE 57 %, MEDLINE 57 %, PubMed Health 53 %, Epistemonikos 49 % and TRIP 33 %. EMBASE contained the highest number of unique records (n = 43). The Cochrane library identified seven unique records and had the highest precision (Pr = 30 %), followed by Epistemonikos (n = 2, Pr = 19 %). No unique records were found in PubMed Health (Pr = 24 %) DARE (Pr = 21 %), TRIP (Pr = 10 %) or MEDLINE (Pr = 10 %). Searching EMBASE and the Cochrane library identified 88 % of all systematic reviews in the reference set, and searching the freely available databases (Cochrane, Epistemonikos, MEDLINE) identified 83 % of all the reviews. The databases were re-analysed after systematic reviews of non-conventional interventions (e.g. yoga, acupuncture) were removed. Similarly, no database identified all the retrieved systematic reviews. EMBASE identified the most relevant systematic reviews (sensitivity 73 %) but also retrieved the most irrelevant citations with Pr = 5 %. The sensitivity of the Cochrane database was 62 %, followed by MEDLINE (60 %), DARE (55 %), PubMed Health (54 %), Epistemonikos (50 %) and TRIP (31 %). The precision of the Cochrane library was the highest (20 %), followed by PubMed Health (Pr = 16 %), DARE (Pr = 13 %), Epistemonikos (Pr = 12 %), MEDLINE (Pr = 6 %), TRIP (Pr = 6 %) and EMBASE (Pr = 5 %). EMBASE contained the most unique records (n = 34). The Cochrane library identified seven unique records. The other databases held no unique records. The coverage of bibliographic databases varies considerably due to differences in their scope and content. Researchers wishing to identify systematic reviews should not rely on one database but search multiple databases.

AIM: To provide a systematic update of the evidence concerning the relationship between economic recession and suicide. METHODS: A keyword search of Ovid Medline, Embase, Embase Classic, PsycINFO and PsycARTICLES was performed to identify studies that had investigated the association between economic recession and suicide. RESULTS: Thirty-eight studies met predetermined selection criteria and 31 of them found a positive association between economic recession and increased suicide rates. Two studies reported a negative association, two articles failed to find such an association, and three studies were inconclusive. CONCLUSION: Economic recession periods appear to increase overall suicide rates, although further research is warranted in this area, particularly in low income countries. PMID:26110126

The Polish Medical Bibliography (Polska Bibliografia Lekarska) contains 350 000 records dating from 1979. These records from the fields of medicine, nursing, dentistry, health care systems and preclinical sciences are from nearly 300 biomedical journals published in Poland. We systematically searched the Polish Medical Bibliography Part II (1996-2006) CD-ROM (July 2006) using both English and Polish phrases for randomized trials, manually checked results and, for the trials identified in this way, sought these on medline and embase. Systematic searching identified records of 680 randomized trials from all areas of health care. Nearly 40% of these were not found on either medline or embase. The Polish Medical Bibliography should be of interest to health care information specialists concerned with comprehensive searches for trials.

Effectiveness of adverse effects search filters: drugs versus medical devices.

Farrah, Kelly; Mierzwinski-Urban, Monika; Cimon, Karen

2016-07-01

The study tested the performance of adverse effects search filters when searching for safety information on medical devices, procedures, and diagnostic tests in MEDLINE and Embase. The sensitivity of 3 filters was determined using a sample of 631 references from 131 rapid reviews related to the safety of health technologies. The references were divided into 2 sets by type of intervention: drugs and nondrug health technologies. Keyword and indexing analysis were performed on references from the nondrug testing set that 1 or more of the filters did not retrieve. For all 3 filters, sensitivity was lower for nondrug health technologies (ranging from 53%-87%) than for drugs (88%-93%) in both databases. When tested on the nondrug health technologies set, sensitivity was lower in Embase (ranging from 53%-81%) than in MEDLINE (67%-87%) for all filters. Of the nondrug records that 1 or more of the filters missed, 39% of the missed MEDLINE records and 18% of the missed Embase records did not contain any indexing terms related to adverse events. Analyzing the titles and abstracts of nondrug records that were missed by any 1 filter, the most commonly used keywords related to adverse effects were: risk, complications, mortality, contamination, hemorrhage, and failure. In this study, adverse effects filters were less effective at finding information about the safety of medical devices, procedures, and tests compared to information about the safety of drugs.

Patient safety and systematic reviews: finding papers indexed in MEDLINE, EMBASE and CINAHL.

To develop search strategies for identifying papers on patient safety in MEDLINE, EMBASE and CINAHL. Six journals were electronically searched for papers on patient safety published between 2000 and 2006. Identified papers were divided into two gold standards: one to build and the other to validate the search strategies. Candidate terms for strategy construction were identified using a word frequency analysis of titles, abstracts and keywords used to index the papers in the databases. Searches were run for each one of the selected terms independently in every database. Sensitivity, precision and specificity were calculated for each candidate term. Terms with sensitivity greater than 10% were combined to form the final strategies. The search strategies developed were run against the validation gold standard to assess their performance. A final step in the validation process was to compare the performance of each strategy to those of other strategies found in the literature. We developed strategies for all three databases that were highly sensitive (range 95%-100%), precise (range 40%-60%) and balanced (the product of sensitivity and precision being in the range of 30%-40%). The strategies were very specific and outperformed those found in the literature. The strategies we developed can meet the needs of users aiming to maximise either sensitivity or precision, or seeking a reasonable compromise between sensitivity and precision, when searching for papers on patient safety in MEDLINE, EMBASE or CINAHL.

Treatment success measured by treatment outcome monitoring (TOM) is a key programmatic output of tuberculosis (TB) control programmes. We performed a systematic literature review on national-level TOM in the 30 European Union (EU)/European Economic Areas (EEA) countries to summarise methods used to collect and report data on TOM. Online reference bibliographic databases PubMed/MEDLINE and EMBASE were searched to identify relevant indexed and non-indexed literature published between January 2000 and August 2010. The search strategy resulted in 615 potentially relevant indexed citations, of which 27 full-text national studies (79 data sets) were included for final analysis. The selected studies were performed in 10 EU/EEA countries and gave a fragmented impression of TOM in the EU/EEA. Publication year, study period, sample size, databases, definitions, variables, patient and outcome categories, and population subgroups varied widely, portraying a very heterogeneous picture. This review confirmed previous reports of considerable heterogeneity in publications of TOM results across EU/EEA countries. PubMed/MEDLINE and EMBASE indexed studies are not a suitable instrument to measure representative TOM results for the 30 EU/EEA countries. Uniform and complete reporting to the centralised European Surveillance System will produce the most timely and reliable results of TB treatment outcomes in the EU/EEA. PMID:22790913

For 481 biomedical open access journals, articles are not searchable in the Directory of Open Access Journals nor in conventional biomedical databases

Background. Open access (OA) journals allows access to research papers free of charge to the reader. Traditionally, biomedical researchers use databases like MEDLINE and EMBASE to discover new advances. However, biomedical OA journals might not fulfill such databases’ criteria, hindering dissemination. The Directory of Open Access Journals (DOAJ) is a database exclusively listing OA journals. The aim of this study was to investigate DOAJ’s coverage of biomedical OA journals compared with the conventional biomedical databases. Methods. Information on all journals listed in four conventional biomedical databases (MEDLINE, PubMed Central, EMBASE and SCOPUS) and DOAJ were gathered. Journals were included if they were (1) actively publishing, (2) full OA, (3) prospectively indexed in one or more database, and (4) of biomedical subject. Impact factor and journal language were also collected. DOAJ was compared with conventional databases regarding the proportion of journals covered, along with their impact factor and publishing language. The proportion of journals with articles indexed by DOAJ was determined. Results. In total, 3,236 biomedical OA journals were included in the study. Of the included journals, 86.7% were listed in DOAJ. Combined, the conventional biomedical databases listed 75.0% of the journals; 18.7% in MEDLINE; 36.5% in PubMed Central; 51.5% in SCOPUS and 50.6% in EMBASE. Of the journals in DOAJ, 88.7% published in English and 20.6% had received impact factor for 2012 compared with 93.5% and 26.0%, respectively, for journals in the conventional biomedical databases. A subset of 51.1% and 48.5% of the journals in DOAJ had articles indexed from 2012 and 2013, respectively. Of journals exclusively listed in DOAJ, one journal had received an impact factor for 2012, and 59.6% of the journals had no content from 2013 indexed in DOAJ. Conclusions. DOAJ is the most complete registry of biomedical OA journals compared with five conventional biomedical databases. However, DOAJ only indexes articles for half of the biomedical journals listed, making it an incomplete source for biomedical research papers in general. PMID:26038727

Wilczynski, Nancy L.; McKibbon, K. Ann; Haynes, R. Brian

2011-01-01

Background: Most methodologic search filters developed for use in large electronic databases such as MEDLINE have low precision. One method that has been proposed but not tested for improving precision is NOTing out irrelevant content. Objective: To determine if search filter precision can be improved by NOTing out the text words and index terms assigned to those articles that are retrieved but are off-target. Design: Analytic survey. Methods: NOTing out unique terms in off-target articles and testing search filter performance in the Clinical Hedges Database. Main Outcome Measures: Sensitivity, specificity, precision and number needed to read (NNR). Results: For all purpose categories (diagnosis, prognosis and etiology) except treatment and for all databases (MEDLINE, EMBASE, CINAHL and PsycINFO), constructing search filters that NOTed out irrelevant content resulted in substantive improvements in NNR (over four-fold for some purpose categories and databases). Conclusion: Search filter precision can be improved by NOTing out irrelevant content. PMID:22195215

To perform a state of the art about the history of kidney transplantation. An exhaustive systematic review of the scientific literature was performed in the Medline database (http://www.ncbi.nlm.nih.gov) and Embase (http://www.embase.com) using different associations of the following keywords (MESH): kidney transplantation, history, vascular anastomosis. From the first vascular ligations to the discovery of ciclosporin, the history of organ transplantation was made of surgical bets and medical discoveries, such as blood group, HLA-system, immunity, etc. The audacity of some surgeons led to the onset of renal transplantation as the treatment of choice for end stage renal disease. This article aims to describe the first surgical methods for vascular anastomosis and renal transplantation. Through a comprehensive search within the archives of the French National Library, the authors provide a precise description of the first renal transplantations performed, the technique that have been used and their authors.

We frequently fail to identify articles relevant to the subject of acute kidney injury (AKI) when searching the large bibliographic databases such as PubMed, Ovid Medline or Embase. To address this issue, we used computer automation to create information search filters to better identify articles relevant to AKI in these databases. We first manually reviewed a sample of 22 992 full-text articles and used prespecified criteria to determine whether each article contained AKI content or not. In the development phase (two-thirds of the sample), we developed and tested the performance of >1.3-million unique filters. Filters with high sensitivity and high specificity for the identification of AKI articles were then retested in the validation phase (remaining third of the sample). We succeeded in developing and validating high-performance AKI search filters for each bibliographic database with sensitivities and specificities in excess of 90%. Filters optimized for sensitivity reached at least 97.2% sensitivity, and filters optimized for specificity reached at least 99.5% specificity. The filters were complex; for example one PubMed filter included >140 terms used in combination, including 'acute kidney injury', 'tubular necrosis', 'azotemia' and 'ischemic injury'. In proof-of-concept searches, physicians found more articles relevant to topics in AKI with the use of the filters. PubMed, Ovid Medline and Embase can be filtered for articles relevant to AKI in a reliable manner. These high-performance information filters are now available online and can be used to better identify AKI content in large bibliographic databases.

Much of the knowledge about the optimal way to perform chest compressions (CC) in newborn infants is derived from animal studies. The objective of this review was to identify studies of CC in newborn term animal models and review the evidence. We also provide an overview of the different models. MEDLINE, EMBASE and CINAHL, until September 29th 2014. Study eligibility criteria and interventions: term newborn animal models where CC was performed. Based on 419 retrieved studies from MEDLINE and 502 from EMBASE, 28 studies were included. No additional studies were identified in CINAHL. Most of the studies were performed in pigs after perinatal transition without long-term follow-up. The models differed widely in methodological aspects, which limits the possibility to compare and synthesize findings. Studies uncommonly reported the method for randomization and allocation concealment, and a limited number were blinded. Only the evidence in favour of the two-thumb encircling hands technique for performing CC, a CC to ventilation ratio of 3:1; and that air can be used for ventilation during CC; was supported by more than one study. Animal studies should be performed and reported with the same rigor as in human randomized trials. Good transitional and survival models are needed to further increase the strength of the evidence derived from animal studies of newborn chest compressions. Copyright © 2015 Elsevier Ireland Ltd.

Gaudet, Laura; Ferraro, Zachary M.; Walker, Mark

2014-01-01

Objective. To determine a precise estimate for the contribution of maternal obesity to macrosomia. Data Sources. The search strategy included database searches in 2011 of PubMed, Medline (In-Process & Other Non-Indexed Citations and Ovid Medline, 1950–2011), and EMBASE Classic + EMBASE. Appropriate search terms were used for each database. Reference lists of retrieved articles and review articles were cross-referenced. Methods of Study Selection. All studies that examined the relationship between maternal obesity (BMI ≥30 kg/m2) (pregravid or at 1st prenatal visit) and fetal macrosomia (birth weight ≥4000 g, ≥4500 g, or ≥90th percentile) were considered for inclusion. Tabulation, Integration, and Results. Data regarding the outcomes of interest and study quality were independently extracted by two reviewers. Results from the meta-analysis showed that maternal obesity is associated with fetal overgrowth, defined as birth weight ≥ 4000 g (OR 2.17, 95% CI 1.92, 2.45), birth weight ≥4500 g (OR 2.77,95% CI 2.22, 3.45), and birth weight ≥90% ile for gestational age (OR 2.42, 95% CI 2.16, 2.72). Conclusion. Maternal obesity appears to play a significant role in the development of fetal overgrowth. There is a critical need for effective personal and public health initiatives designed to decrease prepregnancy weight and optimize gestational weight gain. PMID:25544943

2011-01-01

This project aims to assess the utility of bibliographic databases beyond the three major ones (MEDLINE, EMBASE and Cochrane CENTRAL) for finding controlled trials of complementary and alternative medicine (CAM). Fifteen databases were searched to identify controlled clinical trials (CCTs) of CAM not also indexed in MEDLINE. Searches were conducted in May 2006 using the revised Cochrane highly sensitive search strategy (HSSS) and the PubMed CAM Subset. Yield of CAM trials per 100 records was determined, and databases were compared over a standardized period (2005). The Acudoc2 RCT, Acubriefs, Index to Chiropractic Literature (ICL) and Hom-Inform databases had the highest concentrations of non-MEDLINE records, with more than 100 non-MEDLINE records per 500. Other productive databases had ratios between 500 and 1500 records to 100 non-MEDLINE records—these were AMED, MANTIS, PsycINFO, CINAHL, Global Health and Alt HealthWatch. Five databases were found to be unproductive: AGRICOLA, CAIRSS, Datadiwan, Herb Research Foundation and IBIDS. Acudoc2 RCT yielded 100 CAM trials in the most recent 100 records screened. Acubriefs, AMED, Hom-Inform, MANTIS, PsycINFO and CINAHL had more than 25 CAM trials per 100 records screened. Global Health, ICL and Alt HealthWatch were below 25 in yield. There were 255 non-MEDLINE trials from eight databases in 2005, with only 10% indexed in more than one database. Yield varied greatly between databases; the most productive databases from both sampling methods were Acubriefs, Acudoc2 RCT, AMED and CINAHL. Low overlap between databases indicates comprehensive CAM literature searches will require multiple databases. PMID:19468052

Injury to the abdomen can be blunt or penetrating. Abdominal injury can damage internal organs such as the liver, spleen, kidneys, intestine, and large blood vessels. There are controversies about the best approach to manage abdominal injuries. To assess the effects of surgical and non-surgical interventions in the management of abdominal trauma in a haemodynamically stable and non-peritonitic abdomen. We searched the Cochrane Injuries Group's Specialised Register, The Cochrane Library, Ovid MEDLINE(R), Ovid MEDLINE(R) In-Process & Other Non-Indexed Citations, Ovid MEDLINE(R) Daily and Ovid OLDMEDLINE(R), EMBASE Classic+EMBASE (Ovid), ISI WOS (SCI-EXPANDED, SSCI, CPCI-S & CPSI-SSH), CINAHL Plus (EBSCO), and clinical trials registers, and screened reference lists. We ran the most recent search on 17 September 2015. Randomised controlled trials of surgical interventions and non-surgical interventions involving people with abdominal injury who were haemodynamically stable with no signs of peritonitis. The abdominal injury could be blunt or penetrating. Two review authors independently applied the selection criteria. Data were extracted by two authors using a standard data extraction form, and are reported narratively. Two studies are included, which involved a total of 114 people with penetrating abdominal injuries. Both studies are at moderate risk of bias because the randomisation methods are not fully described, and the original study protocols are no longer available. The studies were undertaken in Finland between 1992 and 2002, by the same two researchers.In one study, 51 people were randomised to surgery or an observation protocol. None of the participants in the study died. Seven people had complications: 5 (18.5%) in the surgical group and 2 (8.3%) in the observation group; the difference was not statistically significant (P = 0.42; Fischer's exact). Among the 27 people who had surgery, 6 (22.2%) surgeries were negative laparotomies, and 15 (55.6%) were non-therapeutic.In the other study, 63 people were randomised to diagnostic laparoscopy (surgery) or an observation protocol. There were no deaths and no unnecessary surgeries in either group. Four people did not receive the intervention they were assigned. There was no difference in therapeutic operations between the two groups: 3 of 28 in the diagnostic laparoscopy group versus 1 of 31 in the observation protocol group (P = 0.337). Based on the findings of 2 studies involving a total of 114 people, there is no evidence to support the use of surgery over an observation protocol for people with penetrating abdominal trauma who have no signs of peritonitis and are stable.

Review of the History of Non-traumatic Spinal Cord Dysfunction.

PubMed

New, Peter Wayne; Biering-Sørensen, Fin

2017-01-01

Background: The incidence of non-traumatic spinal cord dysfunction (SCDys) is reported to be higher than traumatic spinal cord injury (SCI) in many countries. No formal review of the history of SCDys has been published. Objective: This article aims to identify key highlights in the history of SCDys. Method: An electronic literature search was conducted (January 2017) using MEDLINE (1946-2016) and Embase (1974-2016) databases for publications regarding the history of SCDys. Publications on the history of SCI and a selection of neurology textbooks and books on the history of neurology were reviewed for potentially relevant references. The focus of the literature search was on identifying publications that detail key highlights regarding the history of the diagnosis and management of the most common SCDys conditions, as well as those of historical significance. Results: The electronic search of MEDLINE and Embase identified 11 relevant publications. The majority of publications included were identified from the authors' libraries and a selection of books on neurology and the history of neurology. Conclusions: This review outlines the history of SCDys, taking a broader historical perspective and covering the increasing awareness of the role of the spinal cord and knowledge of neuroanatomy. Key milestones in the history of the diagnosis and management of the most common SCDys conditions are presented. An appreciation of the history of SCDys increases our understanding of the large number of people who contributed to our current knowledge of these conditions and in some situations helps guide efforts regarding prevention of SCDys.

Objectives Different surgical techniques have been described in the literature to increase vocal pitch. The purpose of this study is to systematically review these surgeries and perform a meta-analysis to determine which technique increases pitch the most. Data Sources CINAHL, Cochrane, Embase, Medline, PubMed, and Science Direct. Review Methods A systematic review and meta-analysis of the literature was performed using the CINAHL, Cochrane, Embase, Medline, PubMed, and Science Direct databases. Studies were eligible for inclusion if they evaluated pitch-elevating phonosurgical techniques in live humans and performed pre- and postoperative acoustic analysis. Data were gathered regarding surgical technique, pre- and postoperative fundamental frequencies, perioperative care measures, and complications. Results Twenty-nine studies were identified. After applying inclusion and exclusion criteria, a total of 13 studies were included in the meta-analysis. Mechanisms of pitch elevation included increasing vocal cord tension (cricothyroid approximation), shortening the vocal cord length (cold knife glottoplasty, laser-shortening glottoplasty), and decreasing mass (laser reduction glottoplasty). The most common interventions were shortening techniques and cricothyroid approximation (6 studies each). The largest increase in fundamental frequency was seen with techniques that shortened the vocal cords. Preoperative speech therapy, postoperative voice rest, and reporting of patient satisfaction were inconsistent. Many of the studies were limited by low power and short length of follow-up. Conclusions Multiple techniques for elevation of vocal pitch exist, but vocal cord shortening procedures appear to result in the largest increase in fundamental frequency.

Background Inadequately managed pain is a risk factor for chronic postsurgical pain (CPSP), a growing public health challenge. Multidisciplinary pain-management programs with psychological approaches, including cognitive behavioral therapy (CBT), acceptance and commitment therapy (ACT), and mindfulness-based psychotherapy, have shown efficacy as treatments for chronic pain, and show promise as timely interventions in the pre/perioperative periods for the management of PSP. We reviewed the literature to identify randomized controlled trials evaluating the efficacy of these psychotherapy approaches on pain-related surgical outcomes. Materials and methods We searched Medline, Medline-In-Process, Embase and Embase Classic, and PsycInfo to identify studies meeting our search criteria. After title and abstract review, selected articles were rated for risk of bias. Results Six papers based on five trials (four back surgery, one cardiac surgery) met our inclusion criteria. Four papers employed CBT and two CBT-physiotherapy variant; no ACT or mindfulness-based studies were identified. Considerable heterogeneity was observed in the timing and delivery of psychological interventions and length of follow-up (1 week to 2–3 years). Whereas pain-intensity reporting varied widely, pain disability was reported using consistent methods across papers. The majority of papers (four of six) reported reduced pain intensity, and all relevant papers (five of five) found improvements in pain disability. General limitations included lack of large-scale data and difficulties with blinding. Conclusion This systematic review provides preliminary evidence that CBT-based psychological interventions reduce PSP intensity and disability. Future research should further clarify the efficacy and optimal delivery of CBT and newer psychological approaches to PSP. PMID:29403322

Literature searching for clinical and cost-effectiveness studies used in health technology assessment reports carried out for the National Institute for Clinical Excellence appraisal system.

Royle, P; Waugh, N

2003-01-01

To contribute to making searching for Technology Assessment Reports (TARs) more cost-effective by suggesting an optimum literature retrieval strategy. A sample of 20 recent TARs. All sources used to search for clinical and cost-effectiveness studies were recorded. In addition, all studies that were included in the clinical and cost-effectiveness sections of the TARs were identified, and their characteristics recorded, including author, journal, year, study design, study size and quality score. Each was also classified by publication type, and then checked to see whether it was indexed in the following databases: MEDLINE, EMBASE, and then either the Cochrane Controlled Trials Register (CCTR) for clinical effectiveness studies or the NHS Economic Evaluation Database (NHS EED) for the cost-effectiveness studies. Any study not found in at least one of these databases was checked to see whether it was indexed in the Science Citation Index (SCI) and BIOSIS, and the American Society of Clinical Oncology (ASCO) Online if a cancer review. Any studies still not found were checked to see whether they were in a number of additional databases. The median number of sources searched per TAR was 20, and the range was from 13 to 33 sources. Six sources (CCTR, DARE, EMBASE, MEDLINE, NHS EED and sponsor/industry submissions to National Institute for Clinical Excellence) were used in all reviews. After searching the MEDLINE, EMBASE and NHS EED databases, 87.3% of the clinical effectiveness studies and 94.8% of the cost-effectiveness studies were found, rising to 98.2% when SCI, BIOSIS and ASCO Online and 97.9% when SCI and ASCO Online, respectively, were added. The median number of sources searched for the 14 TARs that included an economic model was 9.0 per TAR. A sensitive search filter for identifying non-randomised controlled trials (RCT), constructed for MEDLINE and using the search terms from the bibliographic records in the included studies, retrieved only 85% of the known sample. Therefore, it is recommended that when searching for non-RCT studies a search is done for the intervention alone, and records are then scanned manually for those that look relevant. Searching additional databases beyond the Cochrane Library (which includes CCTR, NHS EED and the HTA database), MEDLINE, EMBASE and SCI, plus BIOSIS limited to meeting abstracts only, was seldom found to be effective in retrieving additional studies for inclusion in the clinical and cost-effectiveness sections of TARs (apart from reviews of cancer therapies, where a search of the ASCO database is recommended). A more selective approach to database searching would suffice in most cases and would save resources, thereby making the TAR process more efficient. However, searching non-database sources (including submissions from manufacturers, recent meeting abstracts, contact with experts and checking reference lists) does appear to be a productive way of identifying further studies.

The contribution of Latin American and Caribbean countries on culture bound syndromes studies for the ICD-10 revision: key findings from a working in progress.

PubMed

Razzouk, Denise; Nogueira, Bruno; Mari, Jair de Jesus

2011-05-01

This review aims to verify the scientific evidences for the inclusion of culture bound syndromes in the International Classification of Diseases towards its 11th edition based on studies from Latin American and Caribbean countries. Studies were identified in Medline, LILACS and EMBASE databases for the period between 1992 and 2008, and then classified according to the type of study, to the mental disorder, country and number of publications per year. 163 studies were selected and classified: 33 in MedlLne, 90 in EMBASE e 40 in LILACS. The percentage of culture bound-syndrome corresponded to 9% in Medline, 12% in EMBASE e 2.5% in LILACS. Among fifteen studies on cultural bound syndromes, two were about "nervios and ataque de nervios", two about "susto", four about the relationship between religion beliefs, witchery, trance and mental disorders, one with a proposal for new diagnostic category, three about theoretic issues and three about the pathoplasty of mental disorders. The scarcity of studies on culture bound syndromes might be due to the indexation problems hindering the screening of studies; lack of interest on publishing such studies in indexed journals (publication bias) and due to difficulty to access them. There is no robust evidence identified among cross-cultural studies to recommend changes for International Classification of Diseases-11th edition.

Mapping the literature of diagnostic medical sonography.

PubMed Central

Walcott, B M

1999-01-01

Diagnostic medical sonography has been evolving as a recognized allied health occupation since the early 1970s, but no bibliometric studies of the literature of the field have been published. This study, part of the Medical Library Association Nursing and Allied Health Resources Section's Project for Mapping the Literature of Allied Health, attempted to identify the core journals in diagnostic medical sonography and determine how well these journals are indexed by MEDLINE, EMBASE/Excerpta Medica, and the Cumulative Index to Nursing and Allied Health Literature (CINAHL). Citation analysis was done using the three journals listed for the field by the Brandon/Hill list. Characteristics of two of these three journals affected the results to the extent that more data should be gathered to reach conclusions about the literature of diagnostic medical sonography as a whole. Results of the analysis do suggest that the literature of echocardiography, which is a special area of diagnostic medical sonography, is indexed much more completely by MEDLINE and EMBASE/Excerpta Medica than by CINAHL. Suggestions are made for librarians making collection development decisions in this area of allied health. PMID:10427429

E12 sheet plastination: Techniques and applications.

PubMed

Ottone, Nicolas Ernesto; Baptista, Carlos A C; Latorre, Rafael; Bianchi, Homero Felipe; Del Sol, Mariano; Fuentes, Ramon

2017-10-30

Plastination is an anatomical technique that consists of replacing the liquids and fat of specimens by reactive polymers through forced impregnation in a vacuum. These are then polymerized to achieve the final result. E12 sheet plastination involves epoxy resin impregnation of thin (2-4 mm) and ultra-thin (<2 mm) tissue sheets, producing dry, transparent, odorless, non-toxic and long-lasting sheets. E12 sheet plastination techniques were reviewed using MEDLINE, EMBASE and SciELO databases, and manual searches. After searching, 616 records were found using the online and manual searches (MEDLINE, n: 207; EMBASE, n: 346; SciELO, n: 44; Manual search: 23). Finally, 96 records were included in this review (after duplicates and articles unrelated to the subject were excluded). The aim of this work was to review the E12 sheet plastination technique, searching for articles concerning views of it, identifying the different variants implemented by researchers since its creation by Gunther von Hagens, and to identify its applications from teaching and research in anatomy to morphological sciences.

2009-01-01

The potential for disasters exists in all communities. To mitigate the potential catastrophes that confront humanity in the new millennium, an evidence-based approach to disaster management is required urgently. This study moves toward such an evidence-based approach by identifying peer-reviewed publications following a range of disasters and events over the past three decades. Peer-reviewed, event-specific literature was identified using a comprehensive search of the electronically indexed database, MEDLINE (1956-January 2009). An extended comprehensive search was conducted for one event to compare the event-specific literature indexed in MEDLINE to other electronic databases (EMBASE, CINAHL, AMED, CENTRAL, Psych Info, Maternity and Infant Care, EBM Reviews). Following 25 individual disasters or overwhelming crises, a total of 2,098 peer-reviewed, event-specific publications were published in 789 journals (652 publications following disasters/events caused by natural hazards, 966 following human-made/technological disasters/events, and 480 following conflict/complex humanitarian events).The event with the greatest number of peer-reviewed, event-specific publications was the 11 September 2001 terrorist attacks (686 publications). Prehospital and Disaster Medicine published the greatest number of peer-reviewed, event-specific publications (54), followed by Journal of Traumatic Stress (42), Military Medicine (40), and Psychiatric Services (40). The primary topics of event-specific publications were mental health, medical health, and response. When an extended, comprehensive search was conducted for one event, 75% of all peer-reviewed, event-specific publications were indexed in MEDLINE. A broad range of multi-disciplinary journals publish peer reviewed, event-specific publications. While the majority of peer-reviewed, event-specific literature is indexed in MEDLINE, comprehensive search strategies should include EMBASE to increase yield.

2017-01-01

Background: Non-traumatic spinal cord dysfunction (SCDys) is caused by a large range of heterogeneous etiologies. Although most aspects of rehabilitation for traumatic spinal cord injury and SCDys are the same, people with SCDys have some unique rehabilitation issues. Purpose: This article presents an overview of important clinical rehabilitation principles unique to SCDys. Methods: Electronic literature search conducted (January 2017) using MEDLINE and Embase (1990-2016) databases for publications regarding SCDys. The focus of the literature search was on identifying publications that present suggestions regarding the clinical rehabilitation of SCDys. Results: The electronic search of MEDLINE and Embase identified no relevant publications, and the publications included were from the authors' libraries. A number of important clinical rehabilitation principles unique to people with SCDys were identified, including classification issues, general rehabilitation issues, etiology-specific issues, and a role for the rehabilitation physician as a diagnostic clinician. The classification issues were regarding the etiology of SCDys and the International Standards for Neurological Classification of Spinal Cord Injury. The general rehabilitation issues were predicting survival, improvement, and rehabilitation outcomes; admission to spinal rehabilitation units, including selection decision issues; participation in rehabilitation; and secondary health conditions. The etiology-specific issues were for SCDys due to spinal cord degeneration, tumors, and infections. Conclusions: Although there are special considerations regarding the rehabilitation of people with SCDys, such as the potential for progression of the underlying condition, functional improvement is typically significant with adequate planning of rehabilitation programs and special attention regarding the clinical condition of patients with SCDys.

Rivaroxaban in patients with atrial fibrillation: from ROCKET AF to everyday practice.

PubMed

Barón-Esquivias, Gonzalo; Marín, Francisco; Sanmartín Fernandez, Marcelo

2017-05-01

Registries and non-interventional studies offer relevant and complementary information to clinical trials, since they have a high external validity. Areas covered: The information regarding the efficacy and safety of rivaroxaban compared with warfarin, or rivaroxaban alone in clinical practice was reviewed in this manuscript. For this purpose, a search on MEDLINE and EMBASE databases was performed. The MEDLINE and EMBASE search included both medical subject headings (MeSH) and keywords including: atrial fibrillation (AF) OR warfarin OR clinical practice OR ROCKET AF AND rivaroxaban. Case reports were not considered. Expert commentary: In ROCKET AF, rivaroxaban was at least as effective as warfarin for the prevention of stroke in patients with nonvalvular AF at high risk of stroke, but, importantly, with a lesser risk of intracranial, critical and fatal bleedings. A number of observational comparative and non-comparative studies, with more than 60,000 patients included treated with rivaroxaban, have analyzed the efficacy and safety of rivaroxaban in real-life patients with AF in different clinical settings. These studies have shown that in clinical practice, rates of stroke and major bleeding were consistently lower than those reported in ROCKET AF, likely due to the lower thromboembolic and bleeding risk observed in these patients.

Azilsartan medoxomil in the treatment of hypertension: the definitive angiotensin receptor blocker?

PubMed

Barrios, Vivencio; Escobar, Carlos

2013-11-01

Azilsartan medoxomil is the newest angiotensin receptor blocker marketed for the treatment of arterial hypertension. The aim of this article was to review the available evidence about this drug alone or combined with other antihypertensive agents in the treatment of hypertensive population. For this purpose, a search on MEDLINE and EMBASE databases was performed. The MEDLINE and EMBASE search included both medical subject headings (MeSHs) and keywords including azilsartan or azilsartan medoxomil or angiotensin receptor blockers or renin angiotensin system or chlorthalidone and hypertension. References of the retrieved articles were also screened for additional studies. There were no language restrictions. Azilsartan medoxomil has a potent and persistent ability to inhibit binding of angiotensin II to AT1 receptors, which may play a role in its superior blood pressure (BP) -lowering efficacy compared with other drugs, including ramipril, candesartan, valsartan or olmesartan, without an increase of side effects. Chlortalidone is a diuretic which significantly differs from other classic thiazides and has largely demonstrated clinical benefits in outcome trials. The fixed-dose combination of azilsartan and chlorthalidone has been shown to be more effective than other potent combinations of angiotensin receptor blockers plus hydrochlorothiazide, with a good tolerability profile.

Medical leadership, a systematic narrative review: do hospitals and healthcare organisations perform better when led by doctors?

2017-01-01

Introduction Despite common assumptions that doctors are well placed to lead hospitals and healthcare organisations, the peer-reviewed literature contains little evidence on the performance of doctors in leadership roles in comparison with that of non-medical managers. Objectives To determine whether there is an association between the leader’s medical background and management performance in terms of organisational performance or patient outcomes. Methods We searched for peer-reviewed, English language studies using Medline, Embase and Emerald Management between 2005 and 2017. We included quantitative, qualitative and mixed method empirical studies on the performance of senior healthcare managers where participants were described as doctors or leaders and where comparative performance data were provided on non-medical leaders. Studies without full text available, or no organisational, leadership behaviour or patient measures, were excluded. Results The search, conducted in Medline (n=3395), Embase (n=1913) and Emerald Management (n=454) databases, yielded 3926 entries. After the application of inclusion and exclusion criteria, 16 studies remained. Twelve studies found that there were positive differences between medical and non-medical leaders, and eight studies correlated those findings with hospital performance or patient outcomes. Six studies examined the composition of boards of directors; otherwise, there were few common areas of investigation. Five inter-related themes emerged from a narrative analysis: the impact of medical leadership on outcomes; doctors on boards; contribution of qualifications and experience; the medical leader as an individual or part of a team and doctors transitioning into the medical leadership role. Discussion and conclusion A modest body of evidence supports the importance of including doctors on organisational governing boards. Despite many published articles on the topic of whether hospitals and healthcare organisations perform better when led by doctors, there were few empirical studies that directly compared the performance of medical and non-medical managers. This is an under-researched area that requires further funding and focus. PMID:28947438

[Citation rates of medical German-language journals in English-language papers - do they correlate with the Impact Factor, and who cites?].

PubMed

Winkmann, G; Schlutius, S; Schweim, H G

2002-01-25

Several publications are warning that the German language is no longer needed for transmission of scientific data. One of the causes may be the Impact Factor (IF), which appears to be derived predominantly from Anglo-American journals. The aim of this study was to check actual international attention paid to German-language journals, i. e. their citation frequencies in English-language papers. Are these citing rates in English-language articles correlated to the IF, and from where do citing articles originate? Of 25 arbitrarily selected >85 % German-language medical journals, IF as well as language distributions of citing articles were determined by searching publication years 1995 - 2000 in Science Citation Index (SCI). MEDLINE and EMBASE were used as supplementary retrieval systems. (i) The sample journals displayed an average IF = 0.357. A 99 % correlation (Pearson factor r = 0.987; n = 25) was observed between our > constructed< IF 2000 and IF published in Journal Citation Report 2000. This proves Stegmann's IF determination method to be valid. On the average, 53 % German-language and 45 % English-language articles between 1995 - 2000 cited the 1995 - 1999' contributions of the studied journals. No correlation was observed between IF vs. rates of citing articles in English (r <0.1). 64 % of citing English-language articles showed corporate sources in Germany/ Austria/ Switzerland, and 13.5 % authors' institutions in USA. (i) An IF >/=1 is, obviously, very hard to attain by German-language journals. ISI's differentiation between Citing vs. Cited-only Journals (the latter often serving as MEDLINE/ EMBASE sources) during derivation of IF appears unjustified. (ii) English now serves as the predominant communication language in sciences in German-speaking countries, but has not supplanted the German language. Our study reveals remarkable international attention rates remaining.

Using data sources beyond PubMed has a modest impact on the results of systematic reviews of therapeutic interventions.

PubMed

Halladay, Christopher W; Trikalinos, Thomas A; Schmid, Ian T; Schmid, Christopher H; Dahabreh, Issa J

2015-09-01

Searching multiple sources when conducting systematic reviews is considered good practice. We aimed to investigate the impact of using sources beyond PubMed in systematic reviews of therapeutic interventions. We randomly selected 50 Cochrane reviews that searched the PubMed (or MEDLINE) and EMBASE databases and included a meta-analysis of ≥10 studies. We checked whether each eligible record in each review (n = 2,700) was retrievable in PubMed and EMBASE. For the first-listed meta-analysis of ≥10 studies in each review, we examined whether excluding studies not found in PubMed affected results. A median of one record per review was indexed in EMBASE but not in PubMed; a median of four records per review was not indexed in PubMed or EMBASE. Meta-analyses included a median of 13.5 studies; a median of zero studies per meta-analysis was indexed in EMBASE but not in PubMed; a median of one study per meta-analysis was not indexed in PubMed or EMBASE. Meta-analysis using only PubMed-indexed vs. all available studies led to a different conclusion in a single case (on the basis of conventional criteria for statistical significance). In meta-regression analyses, effects in PubMed- vs. non-PubMed-indexed studies were statistically significantly different in a single data set. For systematic reviews of the effects of therapeutic interventions, gains from searching sources beyond PubMed, and from searching EMBASE in particular are modest. Copyright © 2015 Elsevier Inc.

A systematic review of alcohol use and sexual risk-taking in Latin America

PubMed Central

Vagenas, Panagiotis; Lama, Javier R.; Ludford, Kaysia T.; Gonzales, Pedro; Sanchez, Jorge; Altice, Frederick L.

2014-01-01

Objective To provide an account of published literature on the association between alcohol use and sexual risk-taking, focusing on Latin America. Methods A search of MEDLINE, Embase, Web of Science, LILACS, and Cochrane databases identified 561 unique articles. After excluding those that were not directly relevant, 30 studies were retained for review. Results Twenty-seven studies showed direct or indirect associations between alcohol abuse and unprotected/risky sex. Three studies, however, showed no association between these variables, suggesting that the public health message of safer sex may have been effective. Conclusions Further research is needed to identify factors and behaviors that could be modified to reduce the association between alcohol use disorders and risky sexual behavior. PMID:24301738

To determine the optimal databases to search for studies of faith-sensitive interventions for treating depression. We examined 23 health, social science, religious, and grey literature databases searched for an evidence synthesis. Databases were prioritized by yield of (1) search results, (2) potentially relevant references identified during screening, (3) included references contained in the synthesis, and (4) included references that were available in the database. We assessed the impact of databases beyond MEDLINE, EMBASE, and PsycINFO by their ability to supply studies identifying new themes and issues. We identified pragmatic workload factors that influence database selection. PsycINFO was the best performing database within all priority lists. ArabPsyNet, CINAHL, Dissertations and Theses, EMBASE, Global Health, Health Management Information Consortium, MEDLINE, PsycINFO, and Sociological Abstracts were essential for our searches to retrieve the included references. Citation tracking activities and the personal library of one of the research teams made significant contributions of unique, relevant references. Religion studies databases (Am Theo Lib Assoc, FRANCIS) did not provide unique, relevant references. Literature searches for reviews and evidence syntheses of religion and health studies should include social science, grey literature, non-Western databases, personal libraries, and citation tracking activities.

The field of neuro-oncology is rapidly progressing and internalizing many of the recent discoveries coming from research conducted in basic science laboratories worldwide. This systematic review aims to summarize the impact of nanotechnology and biomedical engineering in defining clinically meaningful predictive biomarkers with a potential application in the management of patients with brain tumors. Data were collected through a review of the existing English literature performed on Scopus, MEDLINE, MEDLINE in Process, EMBASE, and/or Cochrane Central Register of Controlled Trials: all available basic science and clinical papers relevant to address the above-stated research question were included and analyzed in this study. Based on the results of this systematic review we can conclude that: (1) the advances in nanotechnology and bioengineering are supporting tremendous efforts in optimizing the methods for genomic, epigenomic and proteomic profiling; (2) a successful translational approach is attempting to identify a growing number of biomarkers, some of which appear to be promising candidates in many areas of neuro-oncology; (3) the designing of Randomized Controlled Trials will be warranted to better define the prognostic value of those biomarkers and biosignatures.

Surgery used to be the treatment of choice in cases of blunt hepatic injury, but this approach gradually changed over the last two decades as increasing non-operative management (NOM) of splenic injury led to its use for hepatic injury. The improvement in critical care monitoring and computed tomographic scanning, as well as the more frequent use of interventional radiology techniques, has helped to bring about this change to non-operative management. Liver trauma ranges from a small capsular tear, without parenchymal laceration, to massive parenchymal injury with major hepatic vein/retrohepatic vena cava lesions. In 1994, the Organ Injury Scaling Committee of the American Association for the Surgery of Trauma (AAST) revised the Hepatic Injury Scale to have a range from grade I to VI. Minor injuries (grade I or II) are the most frequent liver injuries (80% to 90% of all cases); severe injuries are grade III-V lesions; grade VI lesions are frequently incompatible with survival. In the medical literature, the majority of patients who have undergone NOM have low-grade liver injuries. The safety of NOM in high-grade liver lesions, AAST grade IV and V, remains a subject of debate as a high incidence of liver and collateral extra-abdominal complications are still described. To assess the effects of non-operative management compared to operative management in high-grade (grade III-V) blunt hepatic injury. The search for studies was run on 14 April 2014. We searched the Cochrane Injuries Group's Specialised Register, The Cochrane Library, Ovid MEDLINE(R), Ovid MEDLINE(R) In-Process & Other Non-Indexed Citations, Ovid MEDLINE(R) Daily and Ovid OLDMEDLINE(R), Embase Classic+Embase (Ovid), PubMed, ISI WOS (SCI-EXPANDED, SSCI, CPCI-S & CPSI-SSH), clinical trials registries, conference proceedings, and we screened reference lists. All randomised trials that compare non-operative management versus operative management in high-grade blunt hepatic injury. Two authors independently applied the selection criteria to relevant study reports. We used standard methodological procedures as defined by the Cochrane Collaboration. We were unable to find any randomised controlled trials of non-operative management versus operative management in high-grade blunt hepatic injury. In order to further explore the preliminary findings provided by animal models and observational clinical studies that suggests there may be a beneficial effect of non-operative management versus operative management in high-grade blunt hepatic injury, large, high quality randomised trials are needed.

2018-03-15

Objectives The objective of this systematic review was to compare otoacoustic emissions (OAE) with audiometry in their effectiveness to monitor effects of long-term noise exposure on hearing. Methods We conducted a systematic search of MEDLINE, Embase and the non-MEDLINE subset of PubMed up to March 2016 to identify longitudinal studies on effects of noise exposure on hearing as determined by both audiometry and OAE. Results This review comprised 13 articles, with 30-350 subjects in the longitudinal analysis. A meta-analysis could not be performed because the studies were very heterogeneous in terms of measurement paradigms, follow-up time, age of included subjects, inclusion of data points, outcome parameters and method of analysis. Overall there seemed to be small changes in both audiometry and OAE over time. Individual shifts were detected by both methods but a congruent pattern could not be observed. Some studies found that initial abnormal or low-level emissions might predict future hearing loss but at the cost of low specificity due to a high number of false positives. Other studies could not find such predictive value. Conclusions The reported heterogeneity in the studies calls for more uniformity in including, reporting and analyzing longitudinal data for audiometry and OAE. For the overall results, both methods showed small changes from baseline towards a deterioration in hearing. OAE could not reliably detect threshold shifts at individual level. With respect to the predictive value of OAE, the evidence was not conclusive and studies were not in agreement. The reported predictors had low specificity.

The most popular method of training in basic life support and AED use remains instructor-led training courses. This systematic review examines the evidence for different training methods of basic life support providers (laypersons and healthcare providers) using standard instructor-led courses as comparators, to assess whether alternative method of training can lead to effective skill acquisition, skill retention and actual performance whilst using the AED. OVID Medline (including Medline 1950-November 2010; EMBASE 1988-November 2010) was searched using "training" OR "teaching" OR "education" as text words. Search was then combined by using AND "AED" OR "automatic external defibrillator" as MESH words. Additionally, the American Heart Association Endnote library was searched with the terms "AED" and "automatic external defibrillator". Resuscitation journal was hand searched for relevant articles. 285 articles were identified. After duplicates were removed, 172 references were reviewed for relevance. From this 22 papers were scrutinized and 18 were included. All were manikin studies. Four LOE 1 studies, seven LOE 2 studies and three LOE 4 studies were supportive of alternative AED training methods. One LOE 2 study was neutral. Three LOE 1 studies provided opposing evidence. There is good evidence to support alternative methods of AED training including lay instructors, self directed learning and brief training. There is also evidence to support that no training is needed but even brief training can improve speed of shock delivery and electrode pad placement. Features of AED can have an impact on its use and further research should be directed to making devices user-friendly and robust to untrained layperson. Copyright © 2011 Elsevier Ireland Ltd.

EMS Systems in Lower-Middle Income Countries: A Literature Review.

PubMed

Suryanto; Plummer, Virginia; Boyle, Malcolm

2017-02-01

Introduction Prehospital care is one of the many issues that require addressing by lower-middle income countries (LMICs) where approximately 90% of global injuries occur. This may arise from more traffic in LMICs, poor road conditions, lack of public awareness of the importance of road safety, and the lack of ability to provide first aid to the victims. However, prehospital care in LMICs remains underdeveloped. Problem There is insufficient evidence regarding the development of prehospital care among LMICs. Thus, the objective of this study was to investigate the status of Emergency Medical Services (EMS) systems in these countries. A review of medical-related electronic databases was designed to identify the development of EMS systems in LMICs. A search of the literature was undertaken using three electronic databases, CINAHL, Ovid Medline, and EMBASE via Ovid, from their commencement date until the end of July 2015. The grey literature was searched using Google Scholar. Articles were included if they reported on the establishment and current status of an EMS system and were excluded if they were letters to the editor, articles focusing on disaster management, a combination of more than one country if the other country was not a LMIC, written in a language other than English or Bahasa Indonesia, and/or focusing only on in-hospital care. There were 337 articles identified in CINAHL, 731 in Ovid Medline, 891 in EMBASE via Ovid, and 41 in Google Scholar. Based on the title and abstract, 31 articles from CINAHL, 40 from Ovid Medline, 43 from EMBASE, and 11 from Google Scholar were retrieved for further review. There were 92 articles that met the inclusion criteria with 35 articles removed, as they were duplicated, leaving 57 articles to be reviewed. From those 48 countries categorized as LMICs, there were 16 (33.3%) countries that had information about an EMS system, including injury types, patient demographic, prehospital transport, and the obstacles in implementing the prehospital care system. The implementation and development of an EMS system is varied among LMICs. Many LMICs lack an organized EMS system with most ambulances used purely for transport and not as an emergency care vehicle. Financial issues are the most common problems faced by LMICs with support from developed countries a necessity. Suryanto , Plummer V , Boyle M .

To examine indexed health science journals to evaluate the prevalence of Wikipedia citations, identify the journals that publish articles with Wikipedia citations, and determine how Wikipedia is being cited. Bibliometric analysis. Publications in the English language that included citations to Wikipedia were retrieved using the online databases Scopus and Web of Science. To identify health science journals, results were refined using Ulrich's database, selecting for citations from journals indexed in Medline, PubMed, or Embase. Using Thomson Reuters Journal Citation Reports, 2011 impact factors were collected for all journals included in the search. Resulting citations were thematically coded, and descriptive statistics were calculated. 1433 full text articles from 1008 journals indexed in Medline, PubMed, or Embase with 2049 Wikipedia citations were accessed. The frequency of Wikipedia citations has increased over time; most citations occurred after December 2010. More than half of the citations were coded as definitions (n = 648; 31.6%) or descriptions (n=482; 23.5%). Citations were not limited to journals with a low or no impact factor; the search found Wikipedia citations in many journals with high impact factors. Many publications are citing information from a tertiary source that can be edited by anyone, although permanent, evidence based sources are available. We encourage journal editors and reviewers to use caution when publishing articles that cite Wikipedia.

Facial palsy may be complicated by ipsilateral synkinesis or contralateral hyperkinesis. Botulinum toxin is increasingly used in the management of facial palsy; however, the optimum dose, treatment interval, adjunct therapy and performance as compared with alternative treatments have not been well established. This study aimed to systematically review the evidence for the use of botulinum toxin in facial palsy. The Cochrane central register of controlled trials (CENTRAL), MEDLINE(R) (1946 to September 2015) and Embase Classic + Embase (1947 to September 2015) were searched for randomised studies using botulinum toxin in facial palsy. Forty-seven studies were identified, and three included. Their physical and patient-reported outcomes are described, and observations and cautions are discussed. Facial asymmetry has a strong correlation to subjective domains such as impairment in social interaction and perception of self-image and appearance. Botulinum toxin injections represent a minimally invasive technique that is helpful in restoring facial symmetry at rest and during movement in chronic, and potentially acute, facial palsy. Botulinum toxin in combination with physical therapy may be particularly helpful. Currently, there is a paucity of data; areas for further research are suggested. A strong body of evidence may allow botulinum toxin treatment to be nationally standardised and recommended in the management of facial palsy.

The aim of this systematic review is to summarise all available data on the effect of a geriatric evaluation on the multidisciplinary treatment of older cancer patients, focussing on oncologic treatment decisions and the implementation of non-oncologic interventions. A systematic search in MEDLINE and EMBASE for studies on the effect of a geriatric evaluation on oncologic and non-oncologic treatment for older cancer patients. Literature search identified 1654 reports (624 from Medline and 1030 from Embase), of which 10 studies were included in the review. Three studies used a geriatric consultation while seven used a geriatric assessment performed by a cancer specialist, healthcare worker or (research) nurse. Six studies addressed a change in oncologic treatment, the initial treatment plan was modified in a median of 39% of patients after geriatric evaluation, of which two thirds resulted in less intensive treatment. Seven studies focused on the implementation of non-oncologic interventions based on the results of the geriatric evaluation; all but one reported that interventions were suggested for over 70% of patients, even in studies that did not focus specifically on frail older patients. In the other study, implementation of non-oncologic interventions was left to the cancer specialist's discretion. A geriatric evaluation has significant impact on oncologic and non-oncologic treatment decisions in older cancer patients and deserves consideration in the oncologic work-up for these patients.

Use of Simulation Learning Experiences in Physical Therapy Entry-to-Practice Curricula: A Systematic Review

ABSTRACT Purpose: To review the literature on simulation-based learning experiences and to examine their potential to have a positive impact on physiotherapy (PT) learners' knowledge, skills, and attitudes in entry-to-practice curricula. Method: A systematic literature search was conducted in the MEDLINE, CINAHL, Embase Classic+Embase, Scopus, and Web of Science databases, using keywords such as physical therapy, simulation, education, and students. Results: A total of 820 abstracts were screened, and 23 articles were included in the systematic review. While there were few randomized controlled trials with validated outcome measures, some discoveries about simulation can positively affect the design of the PT entry-to-practice curricula. Using simulators to provide specific output feedback can help students learn specific skills. Computer simulations can also augment students' learning experience. Human simulation experiences in managing the acute patient in the ICU are well received by students, positively influence their confidence, and decrease their anxiety. There is evidence that simulated learning environments can replace a portion of a full-time 4-week clinical rotation without impairing learning. Conclusions: Simulation-based learning activities are being effectively incorporated into PT curricula. More rigorously designed experimental studies that include a cost–benefit analysis are necessary to help curriculum developers make informed choices in curriculum design. PMID:25931672

Study Objectives: Characterize disrupted nighttime sleep (DNS) in narcolepsy, an important symptom of narcolepsy. Methods: A panel of international narcolepsy experts was convened in 2011 to build a consensus characterization of DNS in patients with narcolepsy. A literature search of the Medline (1965 to date), Medline In-Process (latest weeks), Embase (1974 to date), Embase Alert (latest 8 weeks), and Biosis (1965 to date) databases was conducted using the following search terms: narcolepsy and disrupted nighttime sleep, disturbed nighttime sleep, fragmented sleep, consolidated sleep, sleep disruption, and narcolepsy questionnaire. The purpose of the literature search was to identify publications characterizing the nighttime sleep of patients with narcolepsy. The panel reviewed the literature. Nocturnal sleep can also be disturbed by REM sleep abnormalities such as vivid dreaming and REM sleep behavior disorder; however, these were not reviewed in the current paper, as we were evaluating for idiopathic sleep disturbances. Results: The literature reviewed provide a consistent characterization of nighttime sleep in patients with narcolepsy as fragmented, with reports of frequent, brief nightly awakenings with difficulties returning to sleep and associated reports of poor sleep quality. Polysomnographic studies consistently report frequent awakenings/arousals after sleep onset, more stage 1 (S1) sleep, and more frequent shifts to S1 sleep or wake from deeper stages of sleep. The consensus of the International Experts' Panel on Narcolepsy was that DNS can be distressing for patients with narcolepsy and that treatment of DNS warrants consideration. Conclusions: Clinicians involved in the management of patients with narcolepsy should investigate patients' quality of nighttime sleep, give weight and consideration to patient reports of nighttime sleep experience, and consider DNS a target for treatment. Citation: Roth T; Dauvilliers Y; Mignot E; Montplaisir J; Paul J; Swick T; Zee P. Disrupted nighttime sleep in narcolepsy. J Clin Sleep Med 2013;9(9):955-965. PMID:23997709

Abstract Objective: This meta-analysis aimed to evaluate the efficiency and safety of tranexamic acid for reducing blood loss and transfusion requirements in patients undergoing total shoulder arthroplasty. Methods: A systematic search was performed in Embase (1980–2017.04, embase.com), Medline (1966–2017.04, medline.com), PubMed (1966–2017.04, pubmed.com), ScienceDirect (1985–2017.04, sciencedirect.com), and Web of Science (1950–2017.04, webofknowledge.com). Study which assessed the efficiency and safety of tranexamic acid in total shoulder arthroplasty was selected. Meta-analysis was performed using Stata 11.0 software. Results: In all, 484 patients from 2 randomized controlled trials (RCTs) and 2 non-RCTs were subjected to meta-analysis. The present meta-analysis demonstrated that there was less total blood loss (mean difference [MD] −172.16, 95% confidence interval [CI] −35.46 to −308.87, P = .01, d = 0.33) and transfusion rate (odds ratio 0.34, 95% CI 0.13 to 0.91, P = .03, d = 0.29) in tranexamic acid groups compared with the control groups. There were no significant differences in duration of surgery (MD 0.02, 95% CI −0.12 to 0.22, P = .89, d = 0.19), length of stay (MD −0.06, 95% CI −0.26 to 0.14, P = .56, d = 0.20), or incidence of adverse effects such as deep venous thrombosis (odds ratio 1.15, 95% CI 0.33 to 4.00, P = .83, d = 0.53). Conclusion: Clinical application of tranexamic acid seemed to result in significant reductions in total blood loss, hemoglobin decline and transfusion requirements following total shoulder arthroplasty. Moreover, no increased risk of the thrombotic events was identified. Due to the limited quality of the evidence currently available, higher quality RCTs are required. PMID:28562553

[Citation rates of medical German-language journals in English-language papers--do they correlate with the impact factor, and who cites? (reprint)].

Several publications are warning that the German language is no longer needed for transmission of scientific data. One of the causes may be the Impact Factor (IF), which appears to be derived predominantly from Anglo-American journals. The aim of this study was to check actual international attention paid to German-language journals, i. e. their citation frequencies in English-language papers. Are these citing rates in English-language articles correlated to the IF, and from where do citing articles originate? Of 25 arbitrarily selected > 85 % German-language medical journals, IF as well as language distributions of citing articles were determined by searching publication years 1995 - 2000 in Science Citation Index (SCI). MEDLINE and EMBASE were used as supplementary retrieval systems. (i) The sample journals displayed an average IF = 0.357. A 99 % correlation (Pearson factor r = 0.987; n = 25) was observed between our "constructed" IF 2000 and IF published in Journal Citation Report 2000. This proves Stegmann's IF determination method to be valid. On the average, 53 % German-language and 45 % English-language articles between 1995 - 2000 cited the 1995 - 1999' contributions of the studied journals. No correlation was observed between IF vs. rates of citing articles in English (r < 0.1). 64 % of citing English-language articles showed corporate sources in Germany/Austria/Switzerland, and 13.5 % authors' institutions in USA. (i) An IF >/= 1 is, obviously, very hard to attain by German-language journals. ISI's differentiation between Citing vs. Cited-only Journals (the latter often serving as MEDLINE/EMBASE sources) during derivation of IF appears unjustified. (ii) English now serves as the predominant communication language in sciences in German-speaking countries, but has not supplanted the German language. Our study reveals remarkable international attention rates remaining.

Estimating the national prevalence of child sexual abuse (CSA) and its association with health and developmental outcomes is the first step in developing prevention strategies. While such data are available from many countries, less is known about the epidemiology of CSA in Japan. For this systematic review, we searched English databases: Embase, Ovid MEDLINE(R) In-Process & Other Non-Indexed Citations, Ovid MEDLINE(R) Daily and Ovid MEDLINE(R), Ovid OLDMEDLINE(R), PsycINFO, and Japanese databases: Cinii, J-Stage, Children's Rainbow Center Japan, Japan Child and Family Research Institute, Japanese Journal of Child Abuse and Neglect to identify articles published before July 2015 examining the lifetime prevalence of CSA in Japan using non-clinical samples. Data were extracted from published reports. We initially identified 606 citations and after abstract review, retrieved 120 publications. Six studies that met the selection criteria and additional two relevant studies were reviewed. The range of contact CSA for females was 10.4%-60.7%, and the prevalence of this type of CSA for males was 4.1%. The range of penetrative CSA for females was 1.3%-8.3% and that for males was 0.5%-1.3%. A number of methodological issues were identified, including a lack of validated measures of CSA, and low response rates. In contrast to a lower prevalence of penetrative CSA, the prevalence of contact CSA among Japanese females may be comparable or higher in relation to international estimates. Future research on children's perceptions of and exposure to sexual abuse, crime and exploitation in Japan is discussed. Copyright © 2017 Elsevier Ltd. All rights reserved.

Objective: To evaluate the effect of implant related treatment on the oral health related quality of life (OHRQoL) of edentulous patients. Methods: The CNKI, Wanfang database and Medline, EMBASE, Cochrane Library databases that include randomized clinical trials comparing implant supported overdentures with conventional complete denture for edentulous patients were retrived. Nine studies involving 769 cases were included and meta-analysis was conducted. Results: The standardized mean difference (SMD) of oral health impact profile (OHIP) score was 1.63 (95% CI: 1.25-2.02) and improved after implant related treatment, which was significantly better than the conventional complete denture (0.87, 95% CI: 0.54-1.20). Conclusions: Implant supported overdentures improved patient's OHRQoL and showed better performance compared to the overdentures complete dentures.

Effects of Pilates method in elderly people: Systematic review of randomized controlled trials.

2015-07-01

The Pilates method has been widely used in physical training and rehabilitation. Evidence regarding the effectiveness of this method in elderly people is limited. Six randomized controlled trials studies involving the use of the Pilates method for elderly people, published prior to December 2013, were selected from the databases PubMed, MEDLINE, Embase, Cochrane, Scielo and PEDro. Three articles suggested that Pilates produced improvements in balance. Two studies evaluated the adherence to Pilates programs. One study assessed Pilates' influence on cardio-metabolic parameters and another study evaluated changes in body composition. Strong evidence was found regarding beneficial effects of Pilates over static and dynamic balance in women. Nevertheless, evidence of balance improvement in both genders, changes in body composition in woman and adherence to Pilates programs were limited. Effects on cardio-metabolic parameters due to Pilates training presented inconclusive results. Pilates may be a useful tool in rehabilitation and prevention programs but more high quality studies are necessary to establish all the effects on elderly populations. Copyright © 2015 Elsevier Ltd.

Dienogest (DNG) is an oral progestin, derivative of 19-nortestosterone, that has recently been introduced for the treatment of endometriosis. This review examines the clinical efficacy, safety and tolerability of DNG in the treatment of endometriosis. The material included in the current manuscript was searched and obtained via Medline, Pubmed and EMBASE, from inception until February 2014. The term 'dienogest' was associated with the following search terms: 'endometriosis', 'pharmacokinetics', 'safety' and 'efficacy'. Several trials demonstrated the clinical efficacy, safety and tolerability of DNG. However the use of DNG is associated with some limitations. So far, no study investigated the potential of contraceptive effect of this treatment and therefore, it should be recommended with other methods of contraception (e.g., barrier methods). A further limitation of the use of DNG as daily therapy in the long term is that the cost of the therapy is higher than other progestins available on the market and combined oral contraceptives. Therefore, future studies should be designed to compare the efficacy and safety of DNG with other progestins.

Chronic wounds are a major health burden and have a severe impact on well-being. This synthesis of qualitative studies was undertaken to inform a health technology assessment of antimicrobial wound dressings. It aimed to explore patients' experiences of chronic wounds and determine improvements for clinical practice. Inclusion criteria included use of qualitative methods, and English language publication. Databases searched included MEDLINE (Ovid), MEDLINE in Process (Ovid), EMBASE (Ovid), CINAHL (EBSCOHost), and PsychInfo (EBSCOHost). Searches were limited to 1990-2014. The method of analysis was Framework synthesis. A total of 20 studies were included. The synthesis confirmed the severe physical, social and psychological impact of the chronic wound. Inadequately controlled pain and sleeplessness, restrictions to lifestyle, and the loss of previous life roles can lead to feelings of hopelessness and helplessness and therefore depression and anxiety. Dressings and dressing changes are a key aspect of treatment and provide opportunities for positive interaction and person centred-care. People with chronic wounds can be supported to live well within the severe physical, psychological and social restrictions of a chronic wound. Effective clinical pain management and the recognition of the experience of acute and chronic pain are of the utmost importance to people with a chronic wound. Treatment should not be purely focused on healing but incorporate symptom management, coping and wellbeing via person-centred and holistic care. Copyright © 2017 Tissue Viability Society.

Interleukin-1α (IL-1α) and its receptor antagonist IL-1RA play a pivotal role in skin homeostasis and disease. Although the use of biopsies to sample these cytokines from human skin is widely employed in dermatological practice, knowledge about less invasive, in vivo sampling methods is scarce. The aim of this study was to provide an overview of such methods by systematically reviewing studies in Medline, EMBASE, Web of Science and Cochrane Library using combinations of the terms "IL-1α", IL-1RA", "skin", "human", including all possible synonyms. Quality was assessed using the STrengthening the Reporting of OBservational studies in Epidemiology (STROBE) checklist. The search, performed on 14 October 2016, revealed 10 different sampling methods, with varying degrees of invasiveness and wide application spectrum, including assessment of both normal and diseased skin, from several body sites. The possibility to sample quantifiable amounts of cytokines from human skin with no or minimal discomfort holds promise for linking clinical outcomes to molecular profiles of skin inflammation.

The aim of this paper is to summarise the knowledge about the anatomy, embryology and anthropology of the mandible and the mandibular foramen and also to highlight the most important clinical implications of the current studies regarding anaesthesia performed in the region of the mandible. An electronic journal search was undertaken to identify all the relevant studies published in English. The search included MEDLINE and EMBASE databases and years from 1950 to 2012. The subject search used a combination of controlled vocabulary and free text based on the search strategy for MEDLINE using key words: 'mandible', 'mandibular', 'foramen', 'anatomy', 'embryology', 'anthropology', and 'mental'. The reference lists of all the relevant studies and existing reviews were screened for additional relevant publications. Basing on relevant manuscripts, this short review about the anatomy, embryology and anthropology of the mandible and the mandibular foramen was written.

Objectives Oropharyngeal cancer (OPC) is the 6th most common cancer worldwide. Focus on risk factors, improved diagnostic methods and effective management strategies have made it possible to successfully treat OPC. However, the 5-year survival rate has not improved for several years due to multiple treatment complications, tissue morbidity, loss of function and diminished quality of life. Survivors are faced with complications like oral mucositis, hyposalivation, osteoradionecrosis; tissue fibrosis, morbidity from jaw resection; disfigurement and loss of function that further diminish quality of life. The aim of this review is to highlight major complications associated with treatment of OPC via a literature search and review of available options for identification and management of these complications. Data Sources Relevant publications on oral complications of OPC therapy were thoroughly reviewed from the literature published between the years 1988 and 2012. Material and Method We evaluated reported incidence, prevalence and risk factors for oral complications of chemotherapy and radiotherapy for OPC. The authors conducted electronic search using English language databases namely PubMed Plus, Medline (Pre-Medline and Medline), Cochrane Database of systematic reviews (evidence-based medicine), Dentistry & Oral sciences source, AccessScience, Embase, Evidence-Based Medicine Reviews Multifile, Google Scholar, ISI Journal Citation Reports, Ovid Multi-Database. Conclusion We identified the most common complications associated with the treatment of oral cancers. Based on the information gathered, there is evidence that survival of OPC extends beyond eradication of the diseased tissue. Understanding the potential treatment complications and utilizing available resources to prevent and minimize them are important. Caring for OPC survivors should be a multidisciplinary team approach involving the dentist, oncologist, internist and social worker to improve the currently stagnant 5-year survival rate of OPC. More emphasis on improved quality of life after elimination of the cancer will ultimately improve OPC survivorship. PMID:23444208

Agostini, Paula; Singh, Sally

2009-06-01

Thoracic surgery may cause reduced respiratory function and pulmonary complications, with associated increased risk of mortality. Postoperative physiotherapy aims to reverse atelectasis and secretion retention, and may include incentive spirometry. To review the evidence for incentive spirometry, examining the physiological basis, equipment and its use following thoracic surgery. MEDLINE was searched from 1950 to January 2008, EMBASE was searched from 1980 to January 2008, and CINAHL was searched from 1982 to January 2008, all using the OVID interface. The search term was: '[incentive spirometry.mp]'. The Cochrane Library was searched using the terms 'incentive spirometry' and 'postoperative physiotherapy'. The Chartered Society of Physiotherapy Resource Centre was also searched, and a hand search was performed to follow-up references from the retrieved studies. Non-scientific papers were excluded, as were papers that did not relate to thoracic surgery or the postoperative treatment of patients with incentive spirometry. Initially, 106 studies were found in MEDLINE, 99 in EMBASE and 42 in CINAHL. Eight references were found in the Cochrane Library and one paper in the Chartered Society of Physiotherapy Resource Centre. Four studies and one systematic review investigating the effects of postoperative physiotherapy and incentive spirometry in thoracic surgery patients were selected and reviewed. Physiological evidence suggests that incentive spirometry may be appropriate for lung re-expansion following major thoracic surgery. Based on sparse literature, postoperative physiotherapy regimes with, or without, the use of incentive spirometry appear to be effective following thoracic surgery compared with no physiotherapy input.

Objectives To examine indexed health science journals to evaluate the prevalence of Wikipedia citations, identify the journals that publish articles with Wikipedia citations, and determine how Wikipedia is being cited. Design Bibliometric analysis. Study selection Publications in the English language that included citations to Wikipedia were retrieved using the online databases Scopus and Web of Science. Data sources To identify health science journals, results were refined using Ulrich’s database, selecting for citations from journals indexed in Medline, PubMed, or Embase. Using Thomson Reuters Journal Citation Reports, 2011 impact factors were collected for all journals included in the search. Data extraction Resulting citations were thematically coded, and descriptive statistics were calculated. Results 1433 full text articles from 1008 journals indexed in Medline, PubMed, or Embase with 2049 Wikipedia citations were accessed. The frequency of Wikipedia citations has increased over time; most citations occurred after December 2010. More than half of the citations were coded as definitions (n=648; 31.6%) or descriptions (n=482; 23.5%). Citations were not limited to journals with a low or no impact factor; the search found Wikipedia citations in many journals with high impact factors. Conclusions Many publications are citing information from a tertiary source that can be edited by anyone, although permanent, evidence based sources are available. We encourage journal editors and reviewers to use caution when publishing articles that cite Wikipedia. PMID:24603564

Eligible studies published before 31 Dec 2013 were identified from the following databases: Ovid Medline, EMBASE, PsycINFO, Scopus, Cochrane Library, CINAHL Plus, and Web of Science. Eligible studies published before 31, Dec 2013 were identified from the following databases: Ovid Medline, EMBASE, psycINFO, Scopus, Cochrane Library, CINAHL Plus, and Web of Science. Eight studies aiming to identify MDD in CHD patients were included, and there were 10 self-reporting questionnaires (such as PHQ-2, PHQ-9, PHQ categorical algorithm, HADS-D, BDI, BDI-II, BDI-II-cog, CES-D, SCL-90, 2 simple yes/no items) and 1 observer rating scale (Ham-D). For MDD alone, the sensitivity and specificity of various screening tools at the validity and optimal cut-off point varied from 0.34 [0.19, 0.52] to 0.96 [0.78, 1.00] and 0.69 [0.65, 0.73] to 0.97 [0.93, 0.99]. Results showed PHQ-9 (≥10), BDI-II (³14 or ≥16), and HADS-D (≥5 or ≥4) were widely used for screening MDD in CHD patients. There is no consensus on the optimal screening tool for MDD in CHD patients. When evaluating the performance of a screening tool, balancing the high sensitivity and negative predictive value (NPV) between specificity and positive predictive value (PPV) for screening or diagnostic purpose should be considered. After screening, further diagnosis, appropriate management, and necessary referral may also improve cardiovascular outcomes.

Provider communication about HPV vaccination: A systematic review

Gilkey, Melissa B.; McRee, Annie-Laurie

2016-01-01

abstract Background. Improving HPV vaccination coverage in the US will require healthcare providers to recommend the vaccine more effectively. To inform quality improvement efforts, we systematically reviewed studies of provider communication about HPV vaccination. Methods. We searched MEDLINE, CINAHL, EMBASE, and POPLINE in August 2015 to identify studies of provider communication about HPV vaccination. Results. We identified 101 qualitative and quantitative studies. Providers less often recommended HPV vaccine if they were uncomfortable discussing sex, perceived parents as hesitant, or believed patients to be low risk. Patients less often received recommendations if they were younger, male, or from racial/ethnic minorities. Despite parents' preference for unambiguous recommendations, providers often sent mixed messages by failing to endorse HPV vaccine strongly, differentiating it from other vaccines, and presenting it as an “optional” vaccine that could be delayed. Conclusion. Interventions are needed to help providers deliver effective recommendations in the complex communication environment surrounding HPV vaccination. PMID:26838681

To review current studies on the effectiveness of neurofeedback as a method of treatment of the core symptoms of autism spectrum disorders (ASD). Studies were selected based on searches in PubMed, Ovid MEDLINE, EMBASE, ERIC, and CINAHL using combinations of the following keywords: 'Neurofeedback' OR 'EEG Biofeedback' OR 'Neurotherapy' OR 'Mu-Rhythm' OR 'SMR' AND 'Autism' OR 'Autism Spectrum Disorder' OR 'Pervasive Developmental Disorder'. The existing evidence does not support the use of neurofeedback in the treatment of ASD. Studies with outcomes in favour of neurofeedback might be showing an improvement in comorbid attention-deficit-hyperactivity disorder symptoms rather than a true improvement in core ASD symptoms. Limitations of this review are those inherent in the studies available, including small sample size, short duration, variable diagnostic criteria, and insufficient control interventions, all causing a lack of generalizability. © The Authors.

Background Madelung's disease is a rare lipid metabolic disorder characterized by diffuse, uncapsulated lipomas in the neck, shoulder, and other areas. It mainly affects middle-aged men and is related to alcohol abuse, and the cause is not clear. Surgical treatments include lipectomy and liposuction. Methods This systematic review analyzed the treatment of Madelung's disease described in 52 articles including complete patient details, published between 2000 and 2015, and retrieved from the Web of Science, PubMed, Medline, and Embase. Results Lipectomy was performed in most cases and achieved more complete removal and better control of iatrogenic lesions of nearby structures than liposuction. Liposuction achieved good cosmetic results and is simpler and less invasive than lipectomy, but clinical experience is limited. Conclusions Both lipectomy and liposuction have advantages and drawbacks. Surgeons should base the choice of optimal treatment on patient characteristics. Novel surgical techniques and etiologically targeted treatments hold promise as future therapies. PMID:29682541

Objectives: Occupational injuries remain an important unresolved issue in many of the developing and developed countries. We aimed to outline the causes, characteristics, measures and impact of occupational injuries among different ethnicities. Materials and Methods: We reviewed the literatures using PUBMED, MEDLINE, Google Scholar and EMBASE search engine using words: “Occupational injuries” and “workplace” between 1984 and 2014. Results: Incidence of fatal occupational injuries decreased over time in many countries. However, it increased in the migrant, foreign born and ethnic minority workers in certain high risk industries. Disproportionate representations of those groups in different industries resulted in wide range of fatality rates. Conclusions: Overrepresentation of migrant workers, foreign born and ethnic minorities in high risk and unskilled occupations warrants effective safety training programs and enforcement of laws to assure safe workplaces. The burden of occupational injuries at the individual and community levels urges the development and implementation of effective preventive programs. PMID:27051619

2018-06-01

To evaluate the quality of reporting in published randomized controlled trials (RTCs) in the field of fall injuries. The 188 RTCs published between 2001 and 2011, indexed in EMBASE and Medline databases were extracted through searching by appropriate keywords and EMTree classification terms. The evaluation trustworthiness was assured through parallel evaluations of two experts in epidemiology and biostatistics. About 40%-75% of papers had problems in reporting random allocation method, allocation concealment, random allocation implementation, blinding and similarity among groups, intention to treat and balancing benefits and harms. Moreover, at least 10% of papers inappropriately/not reported the design, protocol violations, sample size justification, subgroup/adjusted analyses, presenting flow diagram, drop outs, recruitment time, baseline data, suitable effect size on outcome, ancillary analyses, limitations and generalizability. Considering the shortcomings found and due to the importance of the RCTs for fall injury prevention programmes, their reporting quality should be improved.

Calcium silicate-based cements have superior sealing ability, bioactivity, and marginal adaptation, which make them suitable for different dental treatment applications. However, they exhibit some drawbacks such as long setting time and poor handling characteristics. To overcome these limitations calcium silicates are engineered with various constituents to improve specific characteristics of the base material, and are the focus of this review. An electronic search of the PubMed, MEDLINE, and EMBASE via OVID databases using appropriate terms and keywords related to the use, application, and properties of calcium silicate-based cements was conducted. Two independent reviewers obtained and analyzed the full texts of the selected articles. Although the effects of various constituents and additives to the base Portland cement-like materials have been investigated, there is no one particular ingredient that stands out as being most important. Applying nanotechnology and new synthesis methods for powders most positively affected the cement properties. PMID:27773894

Background. Complementary and alternative medicine (CAM) represents a popular therapeutic option for patients with autism spectrum disorder (ASD). Unfortunately, there is a paucity of data regarding the efficacy of CAM in ASD. The aim of the present systematic review is to investigate trials of CAM in ASD. Material and Methods. We searched the following databases: MEDLINE, EMBASE, Cochrane Database of Systematic Reviews, CINAHL, Psychology and Behavioral Sciences Collection, Agricola, and Food Science Source. Results. Our literature search identified 2687 clinical publications. After the title/abstract screening, 139 publications were obtained for detailed evaluation. After detailed evaluation 67 studies were included, from hand search of references we retrieved 13 additional studies for a total of 80. Conclusion. There is no conclusive evidence supporting the efficacy of CAM therapies in ASD. Promising results are reported for music therapy, sensory integration therapy, acupuncture, and massage. PMID:26064157

Node-making process in network meta-analysis of nonpharmacological treatment are poorly reported.

To identify methods to support the node-making process in network meta-analyses (NMAs) of nonpharmacological treatments. We proceeded in two stages. First, we conducted a literature review of guidelines and methodological articles about NMAs to identify methods proposed to lump interventions into nodes. Second, we conducted a systematic review of NMAs of nonpharmacological treatments to extract methods used by authors to support their node-making process. MEDLINE and Google Scholar were searched to identify articles assessing NMA guidelines or methodology intended for NMA authors. MEDLINE, CENTRAL, and EMBASE were searched to identify reports of NMAs including at least one nonpharmacological treatment. Both searches involved articles available from database inception to March 2016. From the methodological review, we identified and extracted methods proposed to lump interventions into nodes. From the systematic review, the reporting of the network was assessed as long as the method described supported the node-making process. Among the 116 articles retrieved in the literature review, 12 (10%) discussed the concept of lumping or splitting interventions in NMAs. No consensual method was identified during the methodological review, and expert consensus was the only method proposed to support the node-making process. Among 5187 references for the systematic review, we included 110 reports of NMAs published between 2007 and 2016. The nodes were described in the introduction section of 88 reports (80%), which suggested that the node content might have been a priori decided before the systematic review. Nine reports (8.1%) described a specific process or justification to build nodes for the network. Two methods were identified: (1) fit a previously published classification and (2) expert consensus. Despite the importance of NMA in the delivery of evidence when several interventions are available for a single indication, recommendations on the reporting of the node-making process in NMAs are lacking, and reporting of the node-making process in NMAs seems insufficient.

To perform a state of the art about methods of evaluation and present results in ablative therapies for localized prostate cancer. A review of the scientific literature was performed in Medline database (http://www.ncbi.nlm.nih.gov) and Embase (http://www.embase.com) using different associations of keywords. Publications obtained were selected based on methodology, language and relevance. After selection, 102 articles were analysed. Analyse the results of ablative therapies is presently difficult considering the heterogeneity of indications, techniques and follow-up. However, results from the most recent and homogeneous studies are encouraging. Oncologically, postoperative biopsies (the most important criteria) are negative (without any tumor cells in the treated area) in 75 to 95%. Functionally, urinary and sexual pre-operative status is spared (or recovered early) in more than 90% of the patients treated. More and more studies underline also the correlation between the results and the technique used considering the volume of the gland and, moreover, the "index lesion" localization. The post-treatment pathological evaluation by biopsies (targeted with MRI or, perhaps in a near future, with innovative ultrasonography) is the corner stone of oncological evaluation of ablative therapies. Ongoing trials will allow to standardize the follow-up and determine the best indication and the best techniques in order to optimize oncological and functional results for each patient treated.

To review ethical, legal and technical aspects of living kidney donor surgery. An exhaustive systematic review of the scientific literature was performed in the Medline database (http://www.ncbi.nlm.nih.gov) and Embase (http://www.embase.com) using different associations of the following keywords: Donor nephrectomy; Kidney paired donation; Kidney transplantation; Laparoscopic nephrectomy; Living donor; Organs trafficking; Robotic assisted nephrectomy; Vaginal extraction. French legal documents have been reviewed using the government portal (http://www.legifrance.gouv.fr). Articles were selected according to methods, language of publication and relevance. A total of 6421 articles were identified; after careful selection, 161 publications were considered of interest and were eligible for our review. The ethical debate focuses on organ shortage, financial incentive, organ trafficking and the recent data suggesting a small but significant increase risk for late renal disease in donor population. Legal decisions aim to increase the number of kidneys available for donation, such as kidney-paired donation that faces several obstacles in France. Laparoscopic approach became widely used, while robotic-assisted donor nephrectomy failed to demonstrate improved outcome as compared with other minimal invasive techniques. Minimally invasive living donor nephrectomy aims to limit side effects in the donor without increasing the morbidity in this specific population of healthy persons; long term surveillance to prevent the onset of renal disease in mandatory.

A large number of trials remain difficult to locate or unpublished for systematic reviews. The objective of this article was to determine the usefulness of making e-mail contact with authors of clinical trials and literature reviews found in MEDLINE to identify unpublished or difficult to locate Randomized Controlled Trials (RCTs). A structured search for detecting RCTs in MEDLINE was made from January 1999 to June 2003; a questionnaire was sent to a random sample of 525 author's mails. Those RCTs obtained were sought in MEDLINE, EMBASE, the Cochrane Controlled Trials Register, LILACS, and ongoing registers. 40 (7.6%) replies were received; 10 previously undescribed and unpublished RCTs and 21 unregistered ongoing RCTs were found. The most frequently given reasons for not publishing were: lack of time for finalizing the statistical analysis and preparing the manuscript, contractual obligations with the pharmaceutical industry, methodologic errors in designing, and editorial rejection. Using the e-mails of authors detected by the search in electronic databases could contribute toward detecting potentially relevant ongoing or unpublished RCTs enabling rapid, straightforward, low-cost systematic review; in addition, the results of this study support the need of universal registration of all studies at their inception.

Background Evidence of diagnostic accuracy for proposed definitions of nocturnal polyuria is currently unclear. Purpose Systematic review to determine population-based evidence of the diagnostic accuracy of proposed definitions of nocturnal polyuria based on data from frequency-volume charts. Methods Seventeen pre-specified search terms identified 351 unique investigations published from 1990 to 2016 in BIOSIS, Embase, Embase Alerts, International Pharmaceutical Abstract, Medline, and Cochrane. Thirteen original communications were included in this review based on pre-specified exclusion criteria. Data were extracted from each paper regarding subject age, sex, ethnicity, health status, sample size, data collection methods, and diagnostic discrimination of proposed definitions including sensitivity, specificity, positive and negative predictive value. Results The sample size of study cohorts, participant age, sex, ethnicity, and health status varied considerably in 13 studies reporting on the diagnostic performance of seven different definitions of nocturnal polyuria using frequency-volume chart data from 4968 participants. Most study cohorts were small, mono-ethnic, including only Caucasian males aged 50 or higher with primary or secondary polyuria that were compared to a control group of healthy men without nocturia in prospective or retrospective settings. Proposed definitions had poor discriminatory accuracy in evaluations based on data from subjects independent from the original study cohorts with findings being similar regarding the most widely evaluated definition endorsed by ICS. Conclusions Diagnostic performance characteristics for proposed definitions of nocturnal polyuria show poor to modest discrimination and are not based on sufficient level of evidence from representative, multi-ethnic population-based data from both females and males of all adult ages.

2017-10-25

For many vital signs, monitoring methods require contact with the patient and/or are invasive in nature. There is increasing interest in developing still and video image-guided monitoring methods that are non-contact and non-invasive. We will undertake a systematic review of still and video image-based monitoring methods. We will perform searches in multiple databases which include MEDLINE, Embase, CINAHL, Cochrane library, IEEE Xplore and ACM Digital Library. We will use OpenGrey and Google searches to access unpublished or commercial data. We will not use language or publication date restrictions. The primary goal is to summarise current image-based vital signs monitoring methods, limited to heart rate, respiratory rate, oxygen saturations and blood pressure. Of particular interest will be the effectiveness of image-based methods compared to reference devices. Other outcomes of interest include the quality of the method comparison studies with respect to published reporting guidelines, any limitations of non-contact non-invasive technology and application in different populations. To the best of our knowledge, this is the first systematic review of image-based non-contact methods of vital signs monitoring. Synthesis of currently available technology will facilitate future research in this highly topical area. PROSPERO CRD42016029167.

2018-05-01

Response shift (RS) has been defined as a change in the meaning of an individual's self-evaluation of his/her health status and quality of life. Several statistical model- and design-based methods have been developed to test for RS in longitudinal data. We reviewed the uptake of these methods in patient-reported outcomes (PRO) literature. CINHAHL, EMBASE, Medline, ProQuest, PsycINFO, and Web of Science were searched to identify English-language articles about RS published until 2016. Data on year and country of publication, PRO measure adopted, RS detection method, type of RS detected, and testing of underlying model assumptions were extracted from the included articles. Of the 1032 articles identified, 101 (9.8%) articles were included in the study. While 54.5 of the articles reported on the Then-test, 30.7% of the articles reported on Oort's or Schmitt's structural equation modeling (SEM) procedure. Newer RS detection methods, such as relative importance analysis and random forest regression, have been used less frequently. Less than 25% reported on testing the assumptions underlying the adopted RS detection method(s). Despite rapid methodological advancements in RS research, this review highlights the need for further research about RS detection methods for complex longitudinal data and standardized reporting guidelines.

A systematic review and critical appraisal of qualitative metasynthetic practice in public health to develop a taxonomy of operations of reciprocal translation.

Reciprocal translation, the understanding of one study's findings in terms of another's, is the foundation of most qualitative metasynthetic methods. In light of the proliferation of metasynthesis methods, the current review sought to create a taxonomy of operations of reciprocal translation using recently published qualitative metasyntheses. On 19 August 2013, MEDLINE, Embase and PsycINFO were searched. Included articles were full reports of metasyntheses of qualitative studies published in 2012 in English-language peer-reviewed journals. Two reviewers, working independently, screened records, assessed full texts for inclusion and extracted data on methods from each included metasynthesis. Systematic review methods used were summarised, and metasynthetic methods were inductively analysed to develop the taxonomy. Of 61 included metasyntheses, 21 (34%) reported fully replicable search strategies and 51 (84%) critically appraised included studies. Based on methods in these metasyntheses, we developed a taxonomy of reciprocal translation with four overlapping categories: visual representation; key paper integration; data reduction and thematic extraction; and line-by-line coding. This systematic review presents an update on methods and reporting currently used in qualitative metasynthesis. It also goes beyond the proliferation of approaches to offer a parsimonious approach to understanding how reciprocal translations are accomplished across metasynthetis methods.

To investigate the effect of group singing on health related quality of life (HRQoL) for adult, amateur singers with chronic health conditions. A literature search for experimental and observational studies and qualitative studies published before February 2014 was undertaken using the following databases: ASSIA (Proquest), CINAHL (Ebsco), EMBASE (OVID), HMIC (OVID), MEDLINE (OVID), MEDLINE in Process (OVID), OpenGrey, PsycINFO (OVID) and PubMed for Epub ahead of print studies. Social Science searches included: Web of Science, Proquest, and Scopus (Elsevier). The records were screened independently by two reviewers. Studies were critiqued using Critical Appraisal Skills Programme tools. The literature search identified 573 papers, from which 18 were included (5 quantitative, 5 qualitative, 8 mixed-methods studies). These included a variety of patient populations including chronic respiratory disease, neurological conditions and mental health. The quantitative studies lacked consistency: two of the seven controlled studies demonstrated additional HRQoL benefits with singing compared to controls, while three of six uncontrolled studies showed improved HRQoL. Qualitative methods were recorded in variable depth. The qualitative data presented a range of benefits of group singing including increased confidence, increased mood and social support. Few negative effects of singing were reported. This systematic review indicates that group singing interventions may have beneficial effects on HRQoL, anxiety, depression and mood. Studies were heterogeneous with significant methodological limitations, allowing only a weak recommendation for group singing as an intervention for adults with chronic health problems. The undertaking of larger controlled and in-depth qualitative studies is warranted. Copyright © 2016 Elsevier Ltd. All rights reserved.

The aim of this review is to compare studies concerning female sterilization in order to define the most suitable approach and device for each patient considering timing, safety, cost-effectiveness, failure rate, complication rate and patient satisfaction. A systematic literature search was conducted in electronic databases MEDLINE-EMBASE-Sciencedirect and Cochrane Library between 2000 and 2012. All original descriptions, case reports, retrospective and review articles on tubal sterilization methods have been considered. Outcome measures were effectiveness, tolerability, procedure complications and female satisfaction. The ideal female sterilization system should be a simple, safe, highly efficient, easily learned, inexpensive, one-time procedure without negative side-effects. Nowadays, the trans-cervical approach is associated with minimal postoperative pain, allowing short hospitalization and fast resumption of daily activities. Laparoscopic and laparotomic approaches are considered second choices, since, particularly in developing countries, the transcervical hysteroscopic methods will increasingly spread within gynaecological clinical practice. Safety issues, hospital stay, costs and surgeons' experience are important factors in decision-making of the method for female sterilization. Hysteroscopic devices should be preferred when possible. The counselling time remains a fundamental step in choice. The decision concerning method depends on the setting, the surgeon's experience, the country's economical development and the woman's preference.

2014-01-01

To systematically review prevalence studies of vegetative state (VS) and minimally conscious state (MCS) in geographically defined populations, to appraise study methods and assess sources of heterogeneity. MEDLINE, EBM Reviews, and EMBASE databases were searched using key terms. Two reviewers independently identified pertinent articles and screened the references for additional studies. Studies measuring the prevalence of VS and/or MCS in a defined population were included, and information on characteristics, methods, and results was extracted. Heterogeneity was quantified through the statistic I. We identified 5 cross-sectional prevalence surveys of VS and 1 of MCS. Prevalence ranged from 0.2 cases per 100,000 inhabitants to 3.4 for VS and was 1.5 per 100,000 for MCS. Relevant heterogeneity (I = 99.0%) prevented us from calculating a summary estimate. The prevalence of trauma cases varied from 21.9% to 53.8%. Variability pertaining to diagnostic criteria, definition of case, and methods of ascertainment was found. In the few prevalence studies of VS and MCS that were identified, the estimates showed high variability and could not be pooled. Future studies should consider using comparable methods for the definition, ascertainment, and confirmation of cases.

To examine the safety and efficacy of topical use of tranexamic acid (TA) in total knee arthroplasty (TKA). An electronic literature search of PubMed Medline; Ovid Medline; Embase; and the Cochrane Library was performed, identifying studies published in any language from 1966 to February 2013. The studies enrolled adults undergoing a primary TKA, where topical TA was used. Inverse variance statistical method and either a fixed or random effect model, depending on the absence or presence of statistical heterogeneity were used; subgroup analysis was performed when possible. We identified a total of seven eligible reports for analysis. Our meta-analysis indicated that when compared with the control group, topical application of TA limited significantly postoperative drain output (mean difference: -268.36ml), total blood loss (mean difference=-220.08ml), Hb drop (mean difference=-0.94g/dL) and lowered the risk of transfusion requirements (risk ratio=0.47, 95CI=0.26-0.84), without increased risk of thromboembolic events. Sub-group analysis indicated that a higher dose of topical TA (>2g) significantly reduced transfusion requirements. Although the present meta-analysis proved a statistically significant reduction of postoperative blood loss and transfusion requirements with topical use of TA in TKA, the clinical importance of the respective estimates of effect size should be interpreted with caution.

Abstract Objective To determine the nature, scope and effectiveness of interventions to reduce the household economic burden of illness or injury. Methods We systematically reviewed reports published on or before 31 January 2014 that we found in the CENTRAL, CINAHL, Econlit, Embase, MEDLINE, PreMEDLINE and PsycINFO databases. We extracted data from prospective controlled trials and assessed the risk of bias. We narratively synthesized evidence. Findings Nine of the 4330 studies checked met our inclusion criteria – seven had evaluated changes to existing health-insurance programmes and two had evaluated different modes of delivering information. The only interventions found to reduce out-of-pocket expenditure significantly were those that eliminated or substantially reduced co-payments for a given patient population. However, the reductions only represented marginal changes in the total expenditures of patients. We found no studies that had been effective in addressing broader household economic impacts – such as catastrophic health expenditure – in the disease populations investigated. Conclusion In general, interventions designed to reduce the complex household economic burden of illness and injury appear to have had little impact on household economies. We only found a few relevant studies using rigorous study designs that were conducted in defined patient populations. The studies were limited in the range of interventions tested and they evaluated only a narrow range of household economic outcomes. There is a need for method development to advance the measurement of the household economic consequences of illness and injury and facilitate the development of innovative interventions to supplement the strategies based on health insurance.

Despite common assumptions that doctors are well placed to lead hospitals and healthcare organisations, the peer-reviewed literature contains little evidence on the performance of doctors in leadership roles in comparison with that of non-medical managers. To determine whether there is an association between the leader's medical background and management performance in terms of organisational performance or patient outcomes. We searched for peer-reviewed, English language studies using Medline, Embase and Emerald Management between 2005 and 2017. We included quantitative, qualitative and mixed method empirical studies on the performance of senior healthcare managers where participants were described as doctors or leaders and where comparative performance data were provided on non-medical leaders. Studies without full text available, or no organisational, leadership behaviour or patient measures, were excluded. The search, conducted in Medline (n=3395), Embase (n=1913) and Emerald Management (n=454) databases, yielded 3926 entries. After the application of inclusion and exclusion criteria, 16 studies remained. Twelve studies found that there were positive differences between medical and non-medical leaders, and eight studies correlated those findings with hospital performance or patient outcomes. Six studies examined the composition of boards of directors; otherwise, there were few common areas of investigation. Five inter-related themes emerged from a narrative analysis: the impact of medical leadership on outcomes; doctors on boards; contribution of qualifications and experience; the medical leader as an individual or part of a team and doctors transitioning into the medical leadership role. A modest body of evidence supports the importance of including doctors on organisational governing boards. Despite many published articles on the topic of whether hospitals and healthcare organisations perform better when led by doctors, there were few empirical studies that directly compared the performance of medical and non-medical managers. This is an under-researched area that requires further funding and focus. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017. All rights reserved.

2014-01-01

Objective To evaluate the safety profile of nicergoline compared with placebo and other active agents from published randomised controlled trials. Design Systematic review and meta-analysis of nicergoline compared with placebo and other active agents across various indications. Data sources MEDLINE, Medline-in-process, Cochrane, EMBASE, EMBASE alerts, Cochrane Central Register of Controlled Trials (CENTRAL), Cochrane Database of Systematic Reviews (CDSR) and Cochrane Methodology Register (CMR) for all the randomised controlled trials, open-label or blinded, in adults treated with nicergoline. Studies published until August 2013 were included. Review method 29 studies were included for data extraction. The studies included in this review were majorly from European countries and mostly in cerebrovascular disease (n=15) and dementia (n=8). Results The treatment withdrawals were comparatively lower in the nicergoline group as compared with the placebo group (RR=0.92; 95% CI 0.7 to 1.21) and other active comparators (RR=0.45; 95% CI 0.10 to 1.95), but the difference was non-significant. Incidence of any adverse events (AEs) was slightly higher (RR=1.05; 95% CI 0.93 to 1.2) while incidence of serious AEs was lower (RR=0.85; 95% CI 0.50 to 1.45) in the nicergoline compared with placebo group. Frequency of anxiety was significantly lower in nicergoline as compared with placebo (p=0.01). Other AEs including diarrhoea, gastric upset, dizziness and drowsiness were less frequent in the nicergoline group when compared with placebo/active drugs, but the difference was non-significant. Frequency of hypotension and hot flushes was slightly higher in the nicergoline group but the difference was non-significant. None of the studies reported any incidence of fibrosis or ergotism with nicergoline treatment. Conclusions Nicergoline is an ergot derivative, but its safety profile is better than other ergot derivatives like ergotamine and ergotoxine. This systematic review and meta-analysis suggests that nicergoline has a good safety profile. None of the studies included in this systematic review reported any incidence of fibrosis or ergotism with nicergoline. PMID:25079927

A large proportion of mindfulness-based therapy trials report statistically significant results, even in the context of very low statistical power. The objective of the present study was to characterize the reporting of "positive" results in randomized controlled trials of mindfulness-based therapy. We also assessed mindfulness-based therapy trial registrations for indications of possible reporting bias and reviewed recent systematic reviews and meta-analyses to determine whether reporting biases were identified. CINAHL, Cochrane CENTRAL, EMBASE, ISI, MEDLINE, PsycInfo, and SCOPUS databases were searched for randomized controlled trials of mindfulness-based therapy. The number of positive trials was described and compared to the number that might be expected if mindfulness-based therapy were similarly effective compared to individual therapy for depression. Trial registries were searched for mindfulness-based therapy registrations. CINAHL, Cochrane CENTRAL, EMBASE, ISI, MEDLINE, PsycInfo, and SCOPUS were also searched for mindfulness-based therapy systematic reviews and meta-analyses. 108 (87%) of 124 published trials reported ≥1 positive outcome in the abstract, and 109 (88%) concluded that mindfulness-based therapy was effective, 1.6 times greater than the expected number of positive trials based on effect size d = 0.55 (expected number positive trials = 65.7). Of 21 trial registrations, 13 (62%) remained unpublished 30 months post-trial completion. No trial registrations adequately specified a single primary outcome measure with time of assessment. None of 36 systematic reviews and meta-analyses concluded that effect estimates were overestimated due to reporting biases. The proportion of mindfulness-based therapy trials with statistically significant results may overstate what would occur in practice.

Bilateral infarction of the medial medulla (MMI) is rare. Limited information is available on clinical characteristics, etiology, and prognosis. High-resolution neuroimaging has a major role in elucidating the underlying stroke mechanism. The aim of this systematic review was to analyze the clinical presentations, stroke mechanisms, and outcomes in patients with bilateral MMI. We performed a systematic review of the literature from 1992-2011 that reported on clinical presentations, stroke mechanism, and/or outcomes in patients with magnetic resonance imaging-proven bilateral MMI. Medline, EMBASE, and Web of Science Scholars Portal were searched without language restriction. Two reviewers independently assessed identified studies to determine eligibility, validity, and quality. The primary outcome was inpatient mortality; a secondary outcome was case fatality at 12 months. We identified 138 articles from Medline, EMBASE, and Scholars Portal including the MeSH terms "brainstem infarction," "medulla," and "bilateral." Twenty-nine articles met our inclusion criteria, including a total of 38 cases with bilateral MMI, and included in our study. These 38 patients had a mean age of 62.2 years and were predominately male (74.2%). The most common clinical presentations were motor weakness in 78.4%, dysarthria in 48.6%, and hypoglossal palsy in 40.5%. The most common vascular pathology was vertebral artery atherosclerosis, in 38.5%. The clinical outcome was poor (mortality, 23.8%; dependency, 61.9%). Bilateral medial medullary infarction is a rare stroke syndrome. Clinical presentations were mostly rostral medullary lesions. Large-artery atherosclerosis and branch disease were the most common stroke mechanisms. The clinical outcome was usually poor. Copyright © 2013 National Stroke Association. Published by Elsevier Inc.

Characterize disrupted nighttime sleep (DNS) in narcolepsy, an important symptom of narcolepsy. A panel of international narcolepsy experts was convened in 2011 to build a consensus characterization of DNS in patients with narcolepsy. A literature search of the Medline (1965 to date), Medline In-Process (latest weeks), Embase (1974 to date), Embase Alert (latest 8 weeks), and Biosis (1965 to date) databases was conducted using the following search terms: narcolepsy and disrupted nighttime sleep, disturbed nighttime sleep, fragmented sleep, consolidated sleep, sleep disruption, and narcolepsy questionnaire. The purpose of the literature search was to identify publications characterizing the nighttime sleep of patients with narcolepsy. The panel reviewed the literature. Nocturnal sleep can also be disturbed by REM sleep abnormalities such as vivid dreaming and REM sleep behavior disorder; however, these were not reviewed in the current paper, as we were evaluating for idiopathic sleep disturbances. The literature reviewed provide a consistent characterization of nighttime sleep in patients with narcolepsy as fragmented, with reports of frequent, brief nightly awakenings with difficulties returning to sleep and associated reports of poor sleep quality. Polysomnographic studies consistently report frequent awakenings/arousals after sleep onset, more stage 1 (S1) sleep, and more frequent shifts to S1 sleep or wake from deeper stages of sleep. The consensus of the International Experts' Panel on Narcolepsy was that DNS can be distressing for patients with narcolepsy and that treatment of DNS warrants consideration. Clinicians involved in the management of patients with narcolepsy should investigate patients' quality of nighttime sleep, give weight and consideration to patient reports of nighttime sleep experience, and consider DNS a target for treatment.

Adaptation refers to the systematic approach for considering the endorsement or modification of recommendations produced in one setting for application in another as an alternative to de novo development. To describe and assess the methods used for adapting health-related guidelines published in peer-reviewed journals, and to assess the quality of the resulting adapted guidelines. We searched Medline and Embase up to June 2015. We assessed the method of adaptation, and the quality of included guidelines. Seventy-two papers were eligible. Most adapted guidelines and their source guidelines were published by professional societies (71% and 68% respectively), and in high-income countries (83% and 85% respectively). Of the 57 adapted guidelines that reported any detail about adaptation method, 34 (60%) did not use a published adaptation method. The number (and percentage) of adapted guidelines fulfilling each of the ADAPTE steps ranged between 2 (4%) and 57 (100%). The quality of adapted guidelines was highest for the "scope and purpose" domain and lowest for the "editorial independence" domain (respective mean percentages of the maximum possible scores were 93% and 43%). The mean score for "rigor of development" was 57%. Most adapted guidelines published in peer-reviewed journals do not report using a published adaptation method, and their adaptation quality was variable.

Liquid Biopsy and its Potential for Management of Hepatocellular Carcinoma.

We summarized the recent findings of liquid biopsy in cancer field and discussed its potential utility in hepatocellular carcinoma. Literature published in MEDLINE, EMBASE, and Science Direct electronic databases was searched and reviewed. Liquid biopsy specially referred to the detection of nucleic acids (circulating cell-free DNA, cfDNA) and circulating tumor cells (CTCs) in the blood of cancer patients. Compared to conventional single-site sampling or biopsy method, liquid biopsy had the advantages such as non-invasiveness, dynamic monitoring, and the most important of all, overcoming the limit of spatial and temporal heterogeneity. The genomic information of cancer could be profiled by genotyping cfDNA/CTC and subsequently applied to make molecular classification, targeted therapy guidance, and unveil drug resistance mechanisms. The serial sampling feature of liquid biopsy made it possible to monitor treatment response in a real-time manner and predict tumor metastasis/recurrence in advance. Liquid biopsy is a non-invasive, dynamic, and informative sampling method with important clinical translational significance in cancer research and practice. Much work needs to be done before it is used in the management of HCC.

The objective of this study is to systematically review the role of positron emission tomography (PET) and PET/computed tomography (PET/CT) with Fluorine-18-Fluorodeoxyglucose (FDG) in patients with osteosarcoma (OS). A comprehensive literature search of published studies through October 10(th), 2012 in PubMed/MEDLINE, Embase and Scopus databases regarding whole-body FDG-PET and FDG-PET/CT in patients with OS was performed. We identified 13 studies including 289 patients with OS. With regard to the staging and restaging of OS, the diagnostic performance of FDG-PET and PET/CT seem to be high; FDG-PET and PET/CT seem to be superior to bone scintigraphy and conventional imaging methods in detecting bone metastases; conversely, spiral CT seems to be superior to FDG-PET in detecting pulmonary metastases from OS. Metabolic imaging may provide additional information in the evaluation of OS patients. The combination of FDG-PET or FDG-PET/CT with conventional imaging methods seems to be a valuable tool in the staging and restaging of OS and may have a relevant impact on the treatment planning.

Percutaneous endoscopic gastrostomy versus nasogastric tube feeding for patients with head and neck cancer: a systematic review

2014-01-01

There are two main enteral feeding strategies—namely nasogastric (NG) tube feeding and percutaneous gastrostomy—used to improve the nutritional status of patients with head and neck cancer (HNC). But up till now there has been no consistent evidence about which method of enteral feeding is the optimal method for this patient group. To compare the effectiveness of percutaneous gastrostomy and NGT feeding in patients with HNC, relevant literature was identified through Medline, Embase, Pubmed, Cochrane, Wiley and manual searches. We included randomized controlled trials (RCTs) and non-experimental studies comparing percutaneous gastrostomy—including percutaneous endoscopic gastrostomy (PEG) and percutaneous fluoroscopic gastrostomy (PFG) —with NG for HNC patients. Data extraction recorded characteristics of intervention, type of study and factors that contributed to the methodological quality of the individual studies. Data were then compared with respect to nutritional status, duration of feeding, complications, radiotherapy delays, disease-free survival and overall survival. Methodological quality of RCTs and non-experimental studies were assessed with separate standard grading scales. It became apparent from our studies that both feeding strategies have advantages and disadvantages. PMID:24453356

Background Positron emission tomography (PET) with fluor-18-deoxy-glucose (FDG) is widely used for diagnosing recurrent or metastatic disease in patients with differentiated thyroid cancer (DTC). Purpose To assess the diagnostic accuracy of FDG-PET for DTC in patients after ablative therapy. Material and Methods A systematic search was conducted in Medline/PubMed, EMBASE, Cochrane Library, Web of Science, and Open Grey looking for all English-language original articles on the performance of FDG-PET in series of at least 20 patients with DTC having undergone ablative therapy including total thyroidectomy. Diagnostic performance measures were pooled using Reitsma’s bivariate model. Results Thirty-four publications between 1996 and 2014 met the inclusion criteria. Pooled sensitivity and specificity were 79.4% (95% confidence interval [CI], 73.9–84.1) and 79.4% (95% CI, 71.2–85.4), respectively, with an area under the curve of 0.858. Conclusion F18-FDG-PET is a useful method for detecting recurrent DTC in patients having undergone ablative therapy. PMID:26163534

Several authors have developed and applied methods to routine data sets to identify the nature and rate of complications following interventional procedures. But, to date, there has been no systematic search for such methods. The objective of this article was to find, classify and appraise published methods, based on analysis of clinical codes, which used routine healthcare databases in a United Kingdom setting to identify complications resulting from interventional procedures. A literature search strategy was developed to identify published studies that referred, in the title or abstract, to the name or acronym of a known routine healthcare database and to complications from procedures or devices. The following data sources were searched in February and March 2013: Cochrane Methods Register, Conference Proceedings Citation Index - Science, Econlit, EMBASE, Health Management Information Consortium, Health Technology Assessment database, MathSciNet, MEDLINE, MEDLINE in-process, OAIster, OpenGrey, Science Citation Index Expanded and ScienceDirect. Of the eligible papers, those which reported methods using clinical coding were classified and summarised in tabular form using the following headings: routine healthcare database; medical speciality; method for identifying complications; length of follow-up; method of recording comorbidity. The benefits and limitations of each approach were assessed. From 3688 papers identified from the literature search, 44 reported the use of clinical codes to identify complications, from which four distinct methods were identified: 1) searching the index admission for specified clinical codes, 2) searching a sequence of admissions for specified clinical codes, 3) searching for specified clinical codes for complications from procedures and devices within the International Classification of Diseases 10th revision (ICD-10) coding scheme which is the methodology recommended by NHS Classification Service, and 4) conducting manual clinical review of diagnostic and procedure codes. The four distinct methods identifying complication from codified data offer great potential in generating new evidence on the quality and safety of new procedures using routine data. However the most robust method, using the methodology recommended by the NHS Classification Service, was the least frequently used, highlighting that much valuable observational data is being ignored.

Consistent with Baldwin and Ford's model (Pers Psychol 41(1):63-105, 1988), training transfer is defined as the generalization of learning from a training to everyday practice in the workplace. The purpose of this review was to examine the influence of work-environment factors, one component of the model hypothesized to influence training transfer within behavioral health. An electronic literature search guided by the Consolidated Framework for Implementation Research's inner setting domain was conducted was conducted on Medline OVID, Medline EMBASE, and PsycINFO databases. Of 9184 unique articles, 169 full-text versions of articles were screened for eligibility, yielding 26 articles meeting inclusion criteria. Results from the 26 studies revealed that overall, having more positive networks and communication, culture, implementation climate, and readiness for implementation can facilitate training transfer. Although few studies have examined the impact of inner setting factors on training transfer, these results suggest organizational context is important to consider with training efforts. These findings have important implications for individuals in the broader health professions educational field.

Background: Given the lack of clear indications for the use of warfarin in the treatment of atrial fibrillation (AF) in patients on hemodialysis and the potential risks that accompany warfarin use in these patients, we systematically reviewed stroke and bleeding outcomes in hemodialysis patients treated with warfarin for AF. Objective: To systematically review the stroke and bleeding outcomes associated with warfarin use in the hemodialysis population to treat AF. Design: Systematic review. Setting: All adult hemodialysis patients. Patients: Patients on hemodialysis receiving warfarin for the management of AF. Measurements: Any type of stroke and/or bleeding outcomes. Methods: MEDLINE(R) In-Process & Other Non-Indexed Citations and MEDLINE(R) via OVID (1946 to January 11, 2017), and EMBASE via OVID (1974 to January 11, 2017) were searched for relevant literature. Inclusion criteria were randomized controlled trials, observational studies, and case series in English that examined stroke and bleeding outcomes in adult population of patients (over 18 years old) who are on hemodialysis and taking warfarin for AF. Studies with less than 10 subjects, case reports, review articles, and editorials were excluded. Quality of selected articles was assessed using Newcastle-Ottawa Scale (NOS). Results: Of the 2340 titles and abstracts screened, 7 met the inclusion criteria. Two studies showed an association between warfarin use and an increased risk of stroke (Hazard Ratio: 1.93-3.36) but no association with an increased risk of bleed (HR: 0.85-1.04), while 4 studies showed no association between warfarin and stroke outcomes (HR: 0.12-1.17) but identified an association between warfarin and increased bleeding outcome (HR: 1.41-3.96). And 1 study reported neither beneficial nor harmful effects associated with warfarin use. Limitations: The major limitation to this review is that the 7 included studies were observational cohort studies, and thus the outcome measures were not specified and predetermined in a research protocol. Conclusion: Our systematic review demonstrated that for patients with AF who are on hemodialysis, warfarin was not associated with reduced outcomes of stroke but was rather associated with increased bleeding events.

Our objective was to conduct a systematic literature review of studies reporting on this association. Methods We used librarian-designed searches of the PubMed Medline and Embase databases to identify primary research articles on pediatric neoplasms and BDs. English language articles from PubMed and Embase up to 10/12/2015, and in PubMed up to 5/12/2017 following an updated search, were eligible for inclusion if they reported primary epidemiological research results on associations between BDs and pediatric malignancies. Two reviewers coded each article based on the title and abstract to identify eligible articles that were abstracted using a structured form. Additional articles were identified through reference lists and other sources. Results were synthesized for pediatric cancers overall and for nine major pediatric cancer subtypes. Results A total of 14,778 article citations were identified, of which 80 met inclusion criteria. Pediatric cancer risk was increased in most studies in association with BDs overall with some notable specific findings, including increased risks for CNS tumors in association with CNS abnormalities and positive associations between rib anomalies and several pediatric cancer types. Conclusions Some children born with BDs may be at increased risk for specific pediatric malignancy types. This work provides a foundation for future investigations that are needed to clarify specific BD types predisposing toward malignancy and possible underlying causes of both BDs and malignancy.

To obtain insight into the patients' experiences during treatment in an acute, closed psychiatric ward. A systematic literature search was conducted in the databases Medline, Embase, CINAHL, and Cochrane. Ten articles were selected. Four main themes emerged from the literature: (a) the inappropriate use of the ward rules, (b) nurses' lack of time for interacting with patients, (c) the feeling of humiliation, and (d) the involvement of significant others. Nurses can use the findings of this systematic review to improve quality of care in acute psychiatric units. © 2015 Wiley Periodicals, Inc.

The aim of this systematic review was to determine which dowel (post) and core system is the most successful when used in vivo to restore endodontically treated teeth. A MEDLINE, a Cochrane, and an EMBASE search (three specified searches) were conducted to identify randomized (RCT) and nonrandomized controlled clinical trials (CCT), cohort (CS), and case control studies (CCS) until January 2008, conducted on humans, and published in English, German, and French, relating to dowel and core systems for restoring endodontically treated teeth. Also, a hand search was conducted, along with contact with the authors when needed. The MEDLINE, Cochrane, and EMBASE searches identified 997, 141, and 25 published articles, respectively. Ten articles from the MEDLINE and seven articles from the Cochrane search (that were also identified in the MEDLINE search) met the inclusion and validity assessment criteria. Six out of the ten studies were RCTs, two were CCTs, and two CSs. The RCT studies suggest that carbon fiber in resin matrix dowels are significantly better than precious alloy cast dowels (number needed to treat, NNT = 8.30). Tapered gold alloy cast dowels are better than ParaPost gold alloy cast dowels (NNT = 13.15). ParaPost prefabricated dowels are slightly better than ParaPost cast dowels (NNT = 175.4). Glass fiber dowels are significantly better than metal screw dowels (NNT = 5.46), but worse than titanium (NNT =-21.73) (moderately). Carbon fiber dowels are worse than gold alloy cast dowels (significantly) (NNT =-5.81) and than amalgam dowels (NNT =-125) (slightly). The CCT studies suggest that metal dowels are better (NNT = 21.73) but also worse than cast dowels (NNT =-33.33) depending on the remaining amount of coronal hard tissue. Quartz fiber dowels show success rates similar to and worse than glass fiber-reinforced dowels (NNT =-37.03). The results from the CS studies suggest that carbon fiber in resin matrix dowels are better (moderately) than carbon fiber + quartz and quartz fiber dowels. Titanium dowels with a composite build-up are better (moderately) than gold alloy cast dowels. According to the studies of the highest levels of evidence, carbon fiber in resin matrix dowels are significantly better than precious alloy cast dowels (RCT). Glass fiber dowels are significantly better than metal screw dowels (RCT) and moderately better than quartz fiber dowels (CCT). Carbon fiber dowels are significantly worse than metal dowels (of precious alloy) (RCT). Prefabricated metal dowels are slightly better than cast dowels (RCT), but moderately worse when no collar of the dentin above the gingiva could be achieved (CCT).

Juxtarenal aortic aneurysms (JAA) account for approximately 15% of abdominal aortic aneurysms. Fenestrated endovascular aneurysm repair (FEVAR) and chimney endovascular aneurysm repair (CH-EVAR) are both effective methods to treat JAAs, but the comparative effectiveness of these treatment modalities is unclear. We searched the PubMed, Medline, Embase, and Cochrane databases to identify English language articles published between January 2005 and September 2013 on management of JAA with fenestrated and chimney techniques to conduct a systematic review to compare outcomes of patients with juxtarenal aortic aneurysm (JAA) treated with the two techniques. We compared nine F-EVAR cohort studies including 542 JAA patients and 8 CH-EVAR cohorts with 158 JAA patients regarding techniques success rates, 30-day mortality, late mortality, endoleak events and secondary intervention rates. The results of this systematic review indicate that both fenestrated and chimney techniques are attractive options for JAAs treatment with encouraging early and mid-term outcomes. PMID:26869488

[Purpose] To review and assess the effectiveness of whole body vibration therapy on the physical function of patients with type II diabetes mellitus. [Subjects and Methods] A computerized database search was performed through PubMed, Medline, EMBASE, the Cochrane Central Register of Controlled Trials, the Physiotherapy Evidence Database, and the reference lists of all relevant articles. The methodological quality was evaluated using the Physiotherapy Evidence Database scale. [Results] Five articles (four studies) with a combined study population of 154 patients with type II diabetes qualified for the inclusion criteria. Our review shows that whole body vibration therapy may have a positive impact on the muscle strength and balance of people with type 2 diabetes mellitus, whereas the effect on their mobility is still under discussion. [Conclusion] There was no sufficient evidence to support the premise that whole body vibration therapy is beneficial for the physical function of people with type II diabetes. Larger and higher-quality trials are needed.

2008-01-01

Objective: To determine the effects of tilt-in-space seating on outcomes for people with neurological or neuromuscular impairment who cannot walk. Data sources: Search through electronic databases (MEDLINE, Embase, CINAHL, AMED). Discussions with researchers who are active in field. Review methods: Selection criteria included interventional studies that investigated the effects of seat tilt on outcome or observational studies that identified outcomes for those who had used tilt-in-space seating in populations with neurological or neuromuscular impairments. Two reviewers independently selected trials for inclusion, assessed quality and extracted data. Results: Nineteen studies were identified which fulfilled the selection criteria. Seventeen of these were essentially before–after studies investigating the immediate effects of tilting the seating. All studies looked at populations with neurological impairment, and most were on children with cerebral palsy (n = 8) or adults with spinal cord injury (n = 8). Reviewer's conclusion: Posterior tilt can reduce pressures at the interface under the pelvis. PMID:18042602

2015-03-01

The Irish government published its primary care strategy, Primary Care: A New Direction in 2001. Progress with the implementation of Primary care teams is modest. The aim of this paper is to map the Irish grey literature and peer-reviewed publications to determine what research has been carried out in relation to primary care teams, the reform process and interdisciplinary working in primary care in Ireland. This scoping review employed three methods: a review of Web of Science, Medline and Embase databases, an email survey of researchers across academic institutions, the HSE and independent researchers and a review of Lenus and the Health Well repository. N = 123 outputs were identified. N = 14 were selected for inclusion. A thematic analysis was undertaken. Common themes identified were resources, GP participation, leadership, clarity regarding roles in primary care teams, skills and knowledge for primary care team working, communication and community. There is evidence of significant problems that disrupt team formation and functioning that warrants more comprehensive research.

Food Sources of Saturated Fat and the Association With Mortality: A Meta-Analysis

PubMed Central

O’Sullivan, Therese A.; Mitrou, Francis; Lawrence, David

2013-01-01

We summarized the data related to foods high in saturated fat and risk of mortality. We searched Cochrane Library, MEDLINE, EMBASE, and ProQuest for studies from January 1952 to May 2012. We identified 26 publications with individual dietary data and all-cause, total cancer, or cardiovascular mortality as endpoints. Pooled relative risk estimates demonstrated that high intakes of milk, cheese, yogurt, and butter were not associated with a significantly increased risk of mortality compared with low intakes. High intakes of meat and processed meat were significantly associated with an increased risk of mortality but were associated with a decreased risk in a subanalysis of Asian studies. The overall quality of studies was variable. Associations varied by food group and population. This may be because of factors outside saturated fat content of individual foods. There is an ongoing need for improvement in assessment tools and methods that investigate food sources of saturated fat and mortality to inform dietary guidelines. PMID:23865702

External fixators in the treatment of midshaft clavicle non-unions: a systematic review.

2014-02-01

Non- or mal-union of the clavicle is reported to occur in up to 15 % of conservatively treated fractures: the purpose of this systematic review is to examine the evidence for the use of external fixation in the treatment of clavicular non-union. We performed a search of MEDLINE and Embase, including all papers using external fixators for the treatment of clavicular non-union. Four papers satisfied our eligibility criteria: three case series and one case-control study. Level of evidence and quality assessment scoring were performed using published methods. Due to the heterogeneity of the study populations and interventions, no attempt at meta-analysis was made. External fixation in hypertrophic non-union of the clavicle, but not atrophic non-union, appears to be a reasonable treatment option. A pragmatic, multicentre, randomised controlled trial comparing external fixation and open reduction internal fixation in the treatment of hypertrophic non-union of the clavicle would be valuable.

Carbon dioxide (CO(2)) balneotherapy is a kind of remedy with a wide spectrum of applications which have been used since the Middle Ages. However, its potential use as an adjuvant therapeutic option in patients with cardiovascular disease is not yet fully clarified. We performed a thorough review of MEDLINE Database, EMBASE, ISI WEB of Knowledge, COCHRANE database and sites funded by balneotherapy centers across Europe in order to recognize relevant studies and aggregate evidence supporting the use of CO(2) baths in various cardiovascular diseases. The three main effects of CO(2) hydrotherapy during whole body or partial immersion, including decline in core temperature, an increase in cutaneous blood flow, and an elevation of the score on thermal sensation, are analyzed on a pathophysiology basis. Additionally, the indications and contra-indications of the method are presented in an evidence-based way, while the need for new methodologically sufficient studies examining the use of CO(2) baths in other cardiovascular substrates is discussed.

Ocular wavefront analysis of aspheric compared with spherical monofocal intraocular lenses in cataract surgery: Systematic review with metaanalysis.

PubMed

Schuster, Alexander K; Tesarz, Jonas; Vossmerbaeumer, Urs

2015-05-01

This review was conducted to compare the physical effect of aspheric IOL implantation on wavefront properties with that of spherical IOL implantation. The peer-reviewed literature was systematically searched in Medline, Embase, Web of Science, Biosis, and the Cochrane Library according to the Cochrane Collaboration method. Inclusion criteria were randomized controlled trials comparing the use of aspheric versus spherical monofocal IOL implantation that assessed visual acuity, contrast sensitivity, or quality of vision. A secondary outcome was ocular wavefront analysis; spherical aberration, higher-order aberrations (HOAs), coma, and trefoil were evaluated. Effects were calculated as standardized mean differences (Hedges g) and were pooled using random-effect models. Thirty-four of 43 studies provided data for wavefront analysis. Aspheric monofocal IOL implantation resulted in less ocular spherical aberration and fewer ocular HOAs than spherical IOLs. This might explain the better contrast sensitivity in patients with aspheric IOLs. Copyright © 2015 ASCRS and ESCRS. Published by Elsevier Inc. All rights reserved.

Introduction. Behavioral and psychological symptoms of dementia (BPSD) are defined as a group of symptoms of disturbed perceptive thought content, mood, or behavior that include agitation, depression, apathy, repetitive questioning, psychosis, aggression, sleep problems, and wandering. Care of patients with BPSD involves pharmacological and nonpharmacological interventions. We reviewed studies of nonpharmacological interventions published in the last 10 years. Methods. We performed a systematic review in Medline and Embase databases, in the last 10 years, until June 2015. Key words used were (1) non-pharmacological interventions, (2) behavioral symptoms, (3) psychological symptoms, and (4) dementia. Results. We included 20 studies published in this period. Among these studies, program activities were more frequent (five studies) and the symptoms more responsive to the interventions were agitation. Discussion. Studies are heterogeneous in many aspects, including size sample, intervention, and instruments of measures. Conclusion. Nonpharmacological interventions are able to provide positive results in reducing symptoms of BPSD. Most studies have shown that these interventions have important and significant efficacy.

2014-01-01

INTRODUCTION: Prevalence of sleep bruxism (SB) in children is subject to discussions in the literature. OBJECTIVE: This study is a systematic literature review aiming to critically assess the prevalence of SB in children. METHODS: Survey using the following research databases: MEDLINE, Cochrane, EMBASE, PubMed, Lilacs and BBO, from January 2000 to February 2013, focusing on studies specifically assessing the prevalence of SB in children. RESULTS: After applying the inclusion criteria, four studies were retrieved. Among the selected articles, the prevalence rates of SB ranged from 5.9% to 49.6%, and these variations showed possible associations with the diagnostic criteria used for SB. CONCLUSION: There is a small number of studies with the primary objective of assessing SB in children. Additionally, there was a wide variation in the prevalence of SB in children. Thus, further, evidence-based studies with standardized and validated diagnostic criteria are necessary to assess the prevalence of SB in children more accurately. PMID:25628080

The application and subsequent investigations in the use of varied osteogenic growth factors in bone regeneration procedures have grown dramatically over the past several years. Owing to this rapid gain in popularity and documentation, a review was undertaken to evaluate the in vivo effects of growth factors on bone regeneration. Using related key words, electronic databases (Medline, Embase, and Cochrane) were searched for articles published from 1999 to April 2010 to find growth factor application in bone regeneration in human or animal models. A total of 63 articles were matched with the inclusion criteria of this study. Bone morphogenetic protein 2 (BMP-2) was the most studied growth factor. Carriers for the delivery, experimental sites, and methods of evaluation were different, and therefore articles did not come to a general agreement. Within the limitations of this review, BMP-2 may be an appropriate growth factor for osteogenesis. Copyright © 2013 Elsevier Inc. All rights reserved.

Laver, Kate; Milte, Rachel; Dyer, Suzanne; Crotty, Maria

2016-01-01

Objective: The aim of this study was to compare the efficacy of two approaches: multicomponent interventions that focus on working with the carer and dyadic interventions that work with both the carer and the person with dementia. Method: A systematic review involving a search of Medline, EMBASE, and PsycINFO in October 2015 was performed. Randomized controlled trials involving carers of people with dementia and comparing multicomponent interventions with usual care were included. Results: Pooling of all studies demonstrated that multicomponent interventions can reduce depressive symptoms, improve quality of life, reduce carer impact, and reduce behavioral and psychological symptoms of dementia as well as caregiver upset with these symptoms. We were unable to find a significant difference in the effects of dyadic interventions in comparison with carer focused interventions for these outcomes. Discussion: Although effect sizes associated with intervention are small, multicomponent interventions are relatively inexpensive to deliver, acceptable, and widely applicable. PMID:27458254

Meta-analysis of Laparoscopic Versus Open Repair of Perforated Peptic Ulcer

PubMed Central

Antoniou, George A.; Koch, Oliver O.; Pointner, Rudolph; Granderath, Frank A.

2013-01-01

Background and Objectives: Laparoscopic treatment of perforated peptic ulcer (PPU) has been introduced as an alternative procedure to open surgery. It has been postulated that the minimally invasive approach involves less operative stress and results in decreased morbidity and mortality. Methods: We conducted a meta-analysis of randomized trials to test this hypothesis. Medline, EMBASE, and the Cochrane Central Register of Randomized Trials databases were searched, with no date or language restrictions. Results: Our literature search identified 4 randomized trials, with a cumulative number of 289 patients, that compared the laparoscopic approach with open sutured repair of perforated ulcer. Analysis of outcomes did not favor either approach in terms of morbidity, mortality, and reoperation rate, although odds ratios seemed to consistently support the laparoscopic approach. Results did not determine the comparative efficiency and safety of laparoscopic or open approach for PPU. Conclusion: In view of an increased interest in the laparoscopic approach, further randomized trials are considered essential to determine the relative effectiveness of laparoscopic and open repair of PPU.

Mechanical Stimulation Protocols of Human Derived Cells in Articular Cartilage Tissue Engineering - A Systematic Review.

PubMed

Khozoee, Baktash; Mafi, Pouya; Mafi, Reza; Khan, Wasim S

2017-01-01

Mechanical stimulation is a key factor in articular cartilage generation and maintenance. Bioreactor systems have been designed and built in order to deliver specific types of mechanical stimulation. The focus has been twofold, applying a type of preconditioning in order to stimulate cell differentiation, and to simulate in vivo conditions in order to gain further insight into how cells respond to different stimulatory patterns. Due to the complex forces at work within joints, it is difficult to simulate mechanical conditions using a bioreactor. The aim of this review is to gain a deeper understanding of the complexities of mechanical stimulation protocols by comparing those employed in bioreactors in the context of tissue engineering for articular cartilage, and to consider their effects on cultured cells. Allied and Complementary Medicine 1985 to 2016, Ovid MEDLINE[R] 1946 to 2016, and Embase 1974 to 2016 were searched using key terms. Results were subject to inclusion and exclusion criteria, key findings summarised into a table and subsequently discussed. Based on this review it is overwhelmingly clear that mechanical stimulation leads to increased chondrogenic properties in the context of bioreactor articular cartilage tissue engineering using human cells. However, given the variability and lack of controlled factors between research articles, results are difficult to compare, and a standardised method of evaluating stimulation protocols proved challenging. With improved standardisation in mechanical stimulation protocol reporting, bioreactor design and building processes, along with a better understanding of joint behaviours, we hope to perform a meta-analysis on stimulation protocols and methods.

Challenges in Valuing Temporary Health States for Economic Evaluation: A Review of Empirical Applications of the Chained Time Trade-Off Method.

PubMed

Stoniute, Julija; Mott, David John; Shen, Jing

2018-05-01

The time trade-off (TTO) technique is commonly used to elicit health state utilities. Nevertheless, when the health states being valued are temporary, the TTO approach may be unsuitable. A variant of TTO- chained TTO-has been suggested to be used when the health states are temporary, but little research has been done on how chained TTO should be conducted. To systematically review the use of chained TTO in valuing temporary health states. A systematic literature search was conducted using the following major databases: Ovid MEDLINE(R), Embase, EBM Reviews, and PsycINFO. Abstracts (full articles if necessary) were screened by two independent reviewers, with a third reviewer resolving any disagreements. The resulting number of articles for review was low (n = 9). All the reviewed studies used face-to-face interviews, most had small sample sizes (<100), and all studies valued a small number of health states (<7), with time horizons typically ranging from 4 weeks to 1 year. All studies discussed methodological issues of using chained TTO, and some compared the results with those generated using other preference elicitation methods. Chained TTO appears to be feasible, consistent, and responsive and allows the valuation of temporary health states that would improve the efficiency and accuracy of decision making in health and health care. Nevertheless, the evidence is limited due to the low number of relevant studies in the literature. Further research is needed to examine the performance and validity of chained TTO compared with conventional TTO in the valuation of temporary health states.

Oppong, Raymond; Jowett, Sue; Roberts, Tracy E.

2015-01-01

Purpose of the study This study seeks to explore methods for conducting economic evaluations alongside multinational trials by conducting a systematic review of the methods used in practice and the challenges that are typically faced by the researchers who conducted the economic evaluations. Methods A review was conducted for the period 2002 to 2012, with potentially relevant articles identified by searching the Medline, Embase and NHS EED databases. Studies were included if they were full economic evaluations conducted alongside a multinational trial. Results A total of 44 studies out of a possible 2667 met the inclusion criteria. Methods used for the analyses varied between studies, indicating a lack of consensus on how economic evaluation alongside multinational studies should be carried out. The most common challenge appeared to be related to addressing differences between countries, which potentially hinders the generalisability and transferability of results. Other challenges reported included inadequate sample sizes and choosing cost-effectiveness thresholds. Conclusions It is recommended that additional guidelines be developed to aid researchers in this area and that these be based on an understanding of the challenges associated with multinational trials and the strengths and limitations of alternative approaches. Guidelines should focus on ensuring that results will aid decision makers in their individual countries. PMID:26121465

2017-01-01

ABSTRACT. The last decade has witnessed substantial progress in acquiring diagnostic biomarkers for the diagnostic workup of cerebrovascular disease (CVD). Advanced neuroimaging methods not only provide a strategic contribution for the differential diagnosis of vascular dementia (VaD) and vascular cognitive impairment (VCI), but also help elucidate the pathophysiological mechanisms ultimately leading to small vessel disease (SVD) throughout its course. Objective: In this review, the novel imaging methods, both structural and metabolic, were summarized and their impact on the diagnostic workup of age-related CVD was analysed. Methods: An electronic search between January 2010 and 2017 was carried out on PubMed/MEDLINE, Institute for Scientific Information Web of Knowledge and EMBASE. Results: The use of full functional multimodality in simultaneous Magnetic Resonance (MR)/Positron emission tomography (PET) may potentially improve the clinical characterization of VCI-VaD; for structural imaging, MRI at 3.0 T enables higher-resolution scanning with greater imaging matrices, thinner slices and more detail on the anatomical structure of vascular lesions. Conclusion: Although the importance of most of these techniques in the clinical setting has yet to be recognized, there is great expectancy in achieving earlier and more refined therapeutic interventions for the effective management of VCI-VaD.

Opioids are one of the most commonly prescribed medicines for chronic pain. However, their use for chronic pain has been controversial. The objective of this literature review was to identify the role of genetic polymorphisms on patient treatment parameters (opioid dose requirements, response, and adverse effects) for opioids used in malignant and nonmalignant chronic pain. The opioids that this review focuses on are codeine, morphine, oxycodone, tramadol, and fentanyl. A literature search of databases Medline and Embase was carried out, and studies up to April 2016 were included in this review. Studies were included based on a combination of key words: chronic pain and related terms, pharmacogenetics and related terms, and opioids and related terms. Among the 1,408 individual papers retrieved from the search in Medline and Embase, 32 original articles were included in this review, with none related to codeine. The 32 papers reported various study designs, opioids, and polymorphisms being studied for associations with treatment outcomes. This literature review reveals that variants in ABCB1, OPRM1, and COMT have been replicated for opioid dosing and variants in ABCB1 have been replicated for both treatment response and adverse effects. Currently, there are few validated studies to form a strong evidence base to support pharmacogenomics testing when initiating opioid therapy. However, the field of pharmacogenomics in chronic pain is likely to expand over the coming years, with the increasing number of treatment options available and larger cohorts being assembled in order to identify true associations. © 2017 American Academy of Pain Medicine.

Biochemical bone turnover markers in diabetes mellitus - A systematic review.

PubMed

Starup-Linde, Jakob; Vestergaard, Peter

2016-01-01

Diabetes mellitus is associated with an increased risk of fractures, which is not explained by bone mineral density. Other markers as bone turnover markers (BTMs) may be useful. To assess the relationship between BTMs, diabetes, and fractures. A systematic literature search was conducted in August 2014. The databases searched were Medline at Pubmed and Embase. Medline at Pubmed was searched by "Diabetes Mellitus" (MESH) and "bone turnover markers" and Embase was searched using the Emtree by "Diabetes Mellitus" and "bone turnover", resulting in 611 studies. The eligibility criteria for the studies were to assess BTM in either type 1 diabetes (T1D) or type 2 diabetes (T2D) patients. Of the 611 eligible studies, removal of duplicates and screening by title and abstract lead to 114 potential studies for full-text review. All these studies were full-text screened for eligibility and 45 studies were included. Two additional studies were added from other sources. Among the 47 studies included there were 1 meta-analysis, 29 cross-sectional studies, 13 randomized controlled trials, and 4 longitudinal studies. Both T1D and T2D were studied. Most studies reported fasting BTM and excluded renal disease. Markers of bone resorption and formation seem to be lower in diabetes patients. Bone specific alkaline phosphatase is normal or increased, which suggests that the matrix becomes hypermineralized in diabetes patients. The BTMs: C-terminal cross-link of collagen, insulin-like growth factor-1, and sclerostin may potentially predict fractures, but longitudinal trials are needed.

To identify barriers of delivering oral health care to older people experienced by dentists. A comprehensive literature search was carried out for studies published in the period January 1990-December 2011, using free text and MESH term search strategies for PubMed (Medline), EMBASE and CINAHL. The initial search identified 236 potentially relevant publications: PubMed (Medline; n = 127), EMBASE (n = 108) and CINAHL (n = 1). After screening of titles and abstracts, 14 publications were revealed as relevant for further review. Seven articles, focusing on dentists delivering oral health care to older people in care homes, were suitable for this review, and seven articles did not meet the previously determined quality criteria. One of these articles also focused on barriers experienced by dentists working in their own practice and delivering oral health care to community-dwelling older people. The most common barriers of delivering oral health care to older people were identified respectively as: the lack of adequate equipment in a care home and no area for treatment available (n = 4) and the lack of adequate reimbursement for working in a care home (n = 5). In addition, the inadequate training and experience in delivering oral health care to older care home residents (n = 2) were mentioned. Four publications indicated the loss of time from private practice as a barrier to deliver oral health care in a care home. We suggest that additional research should be initiated to investigate more in detail the barriers dentists experience in delivering oral health care to older people in their own dental practices. © 2013 John Wiley & Sons A/S.

End-stage kidney disease is a strong risk factor for cardiovascular-specific mortality. Polyphenol-rich interventions may attenuate cardiovascular disease risk factors; however, this has not been systematically evaluated in the hemodialysis population. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, the following databases were searched: Cochrane Library (http://www.cochranelibrary.com/), MEDLINE (https://health.ebsco.com/products/medline-with-full-text), Embase (https://www.elsevier.com/solutions/embase-biomedical-research), and CINAHL (https://www.ebscohost.com/nursing/products/cinahl-databases/cinahl-complete). Meta-analyses were conducted for measures of lipid profile, inflammation, oxidative stress, and blood pressure. Risk of bias was assessed using the Cochrane Collaboration Risk of Bias tool and quality of the body of evidence was assessed by the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) methodology. Twelve studies were included for review. Polyphenol-rich interventions included soy, cocoa, pomegranate, grape, and turmeric. Polyphenol-rich interventions significantly improved diastolic blood pressure (Mean Difference (MD) -5.62 mmHg (95% Confidence Interval (CI) -8.47, -2.78); I ² = 2%; p = 0.0001), triglyceride levels (MD -26.52 mg/dL (95% CI -47.22, -5.83); I ² = 57%; p = 0.01), and myeloperoxidase (MD -90.10 (95% CI -135.84, -44.36); I ² = 0%; p = 0.0001). Included studies generally had low or unclear risks of bias. The results of this review provide preliminary support for the use of polyphenol-rich interventions for improving cardiovascular risk markers in haemodialysis patients. Due to the limited number of studies for individual polyphenol interventions, further studies are required to provide recommendations regarding individual polyphenol intervention and dose.

There are various interventions for guideline implementation in clinical practice, but the effects of these interventions are generally unclear. We conducted a systematic review to identify effective methods of implementing clinical research findings and clinical guidelines to change physician practice patterns, in surgical and general practice. Systematic review of reviews. We searched electronic databases (MEDLINE, EMBASE, and PubMed) for systematic reviews published in English that evaluated the effectiveness of different implementation methods. Two reviewers independently assessed eligibility for inclusion and methodological quality, and extracted relevant data. Fourteen reviews covering a wide range of interventions were identified. The intervention methods used include: audit and feedback, computerized decision support systems, continuing medical education, financial incentives, local opinion leaders, marketing, passive dissemination of information, patient-mediated interventions, reminders, and multifaceted interventions. Active approaches, such as academic detailing, led to greater effects than traditional passive approaches. According to the findings of 3 reviews, 71% of studies included in these reviews showed positive change in physician behavior when exposed to active educational methods and multifaceted interventions. Active forms of continuing medical education and multifaceted interventions were found to be the most effective methods for implementing guidelines into general practice. Additionally, active approaches to changing physician performance were shown to improve practice to a greater extent than traditional passive methods. Further primary research is necessary to evaluate the effectiveness of these methods in a surgical setting.

Evidence synthesis has seen major methodological advances in reducing uncertainty and estimating the sizes of the effects. Much less is known about how to assess the relative value of different outcomes. To identify studies that assessed preferences for outcomes in health conditions. we searched MEDLINE, EMBASE, PsycINFO and the Cochrane Library in February 2014. eligible studies investigated preferences of patients, family members, the general population or healthcare professionals for health outcomes. The intention of this review was to include studies which focus on theoretical alternatives; studies which assessed preferences for distinct treatments were excluded. study characteristics as study objective, health condition, participants, elicitation method, and outcomes assessed in the study were extracted. One hundred and twenty-four studies were identified and categorized into four groups: (1) multi criteria decision analysis (MCDA) (n = 71), (2) rating or ranking (n = 25), (3) utility eliciting (n = 5) and (4) studies comparing different methods (n = 23). The number of outcomes assessed by method group varied. The comparison of different methods or subgroups within one study often resulted in different hierarchies of outcomes. A dominant method most suitable for application in evidence syntheses was not identified. As preferences of patients differ from those of other stakeholders (especially medical professionals), the choice of the group to be questioned is consequential. Further research needs to focus on validity and applicability of the identified methods. © 2014 John Wiley & Sons Ltd.

Use and misuse of mixed methods in population oral health research: A scoping review.

2018-05-30

Despite the known benefits of a mixed methods approach in health research, little is known of its use in the field of population oral health. To map the extent of literature using a mixed methods approach to examine population oral health outcomes. For a comprehensive search of all the available literature published in the English language, databases including PubMed, Dentistry and Oral Sciences Source (DOSS), CINAHL, Web of Science and EMBASE (including Medline) were searched using a range of keywords from inception to October 2017. Only peer-reviewed, population-based studies of oral health outcomes conducted among non-institutionalised participants and using mixed methods were considered eligible for inclusion. Only nine studies met the inclusion criteria and were included in the review. The most frequent oral health outcome investigated was caries experience. However, most studies lacked a theoretical rationale or framework for using mixed methods, or supporting the use of qualitative data. Concurrent triangulation with a convergent design was the most commonly used mixed methods typology for integrating quantitative and qualitative data. The tools used to collect quantitative and qualitative data were mostly limited to surveys and interviews. With growing complexity recognised in the determinants of oral disease, future studies addressing population oral health outcomes are likely to benefit from the use of mixed methods. Explicit consideration of theoretical framework and methodology will strengthen those investigations. Copyright© 2018 Dennis Barber Ltd.

2017-07-01

This paper is a synthesis of the available literature on occupational therapy interventions performed in the adult intensive care unit (ICU). The databases of Ovid MEDLINE, Embase, the Cochrane Library, ClinicalTrials.gov and CINAHL databases were systematically searched from inception through August 2016 for studies of adults who received occupational therapy interventions in the ICU. Of 1,938 citations reviewed, 10 studies met inclusion criteria. Only one study explicitly discussed occupational therapy interventions performed and only one study specifically tested the efficacy of occupational therapy. Future research is needed to clarify the specific interventions and role of occupational therapy in the ICU and the efficacy of these interventions.

Isotretinoin, depression and suicide: a review of the evidence

2005-01-01

There is currently considerable controversy regarding a proposed causal relationship between the use of isotretinoin and depression and suicide. A search was made of the MEDLINE, EMBASE and PsychINFO databases using the search terms ‘isotretinoin’, ‘depression’ and ‘suicide’. Despite numerous case reports linking isotretinoin to depression, suicidal ideation and suicide, there is, as yet, no clear proof of an association. While isotretinoin, used to treat acne vulgaris, has not been demonstrated to be associated with depression or suicide, the possibility of a relatively rare idiosyncratic adverse effect remains. GPs have a role in the clinical application of these findings. PMID:15720936

Treatment guidance for non-multidrug-resistant (MDR) rifampicin-resistant (RMP-R) tuberculosis (TB) is variable. We aimed to undertake a systematic review and meta-analysis of the randomised controlled trial (RCT) data behind such guidelines to identify the most efficacious treatment regimens. Ovid MEDLINE, the Web of Science and EMBASE were mined using search terms for TB, drug therapy and RCTs. Despite 12 604 records being retrieved, only three studies reported treatment outcomes by regimen for patients with non-MDR RMP-R disease, preventing meta-analysis. Our systematic review highlights a substantial gap in the literature regarding evidence-based treatment regimens for RMP-R TB.

It is acknowledged that physicians do not seek the same expert aid for themselves as they would offer their patients. In their preclinical years, medical students appear to espouse comparable behavior. To many, medicine is described as a never-ending path that places the student under heavy stress and burnout from the beginning, leaving him/her vulnerable and with insufficient coping methods. Hence, the objective of this study is to 1) explore the prevalence of stress and burnout among preclinical medical students, and 2) propose solutions to decrease stress and burnout and improve medical education in the preclinical years. A detailed scholarly research strategy using Google Scholar, Scopus, Embase, MEDLINE and PubMed was implemented to highlight key themes that are relevant to preclinical medical students' stress and burnout. Stress varied among different samples of medical students and ranged between 20.9% and 90%. Conversely, burnout ranged between 27% and 75%. Methods that help in reducing the incidence of stress and burnout by promoting strategies that focus on personal engagement, extracurricular activities, positive reinterpretation and expression of emotion, student-led mentorship programs, evaluation systems, career counseling and life coaching should be adopted.

Understanding the nature and causes of medical adverse events may help their prevention. This systematic review explores the types, risk factors, and likely causes of preventable adverse events in the hospital sector. MEDLINE (1970-2008), EMBASE, CINAHL (1970-2005) and the reference lists were used to identify the studies and a structured narrative method used to synthesise the data. Operative adverse events were more common but less preventable and diagnostic adverse events less common but more preventable than other adverse events. Preventable adverse events were often associated with more than one contributory factor. The majority of adverse events were linked to individual human error, and a significant proportion of these caused serious patient harm. Equipment failure was involved in a small proportion of adverse events and rarely caused patient harm. The proportion of system failures varied widely ranging from 3% to 85% depending on the data collection and classification methods used. Operative adverse events are more common but less preventable than diagnostic adverse events. Adverse events are usually associated with more than one contributory factor, the majority are linked to individual human error, and a proportion of these with system failure.

2015-01-01

Objectives This study explores the literature in establishing the value of undergraduate peer-based healthcare ethics teaching as an educational methodology. Methods A narrative review of the literature concerning peer-based ethics teaching was conducted. MEDLINE, EMBASE, CINAHL, SCOPUS databases, and the Cochrane Library, were systematically searched for studies of peer-based ethics or professionalism teaching. Selected studies related peer-based teaching to ethics education outcomes. Results Ten publications were identified. Selected studies were varied in their chosen intervention methodology and analysis. Collectively, the identified studies suggest peer-based ethics education is an effective and valued educational methodology in training healthcare professionals. One paper suggests peer-based ethics teaching has advantages over traditional didactic methods. Peer-based ethics teaching also receives positive feedback from student participants. However, the limited literature base demonstrates a clear need for more evaluation of this pedagogy. Conclusions The current literature base suggests that undergraduate peer based healthcare ethics teaching is valuable in terms of efficacy and student satisfaction. We conclude that the medical community should invest in further study in order to capitalise upon the potential of peer-based ethics teaching in undergraduate healthcare education. PMID:26668050

An increasing number of studies are using health administrative databases for tuberculosis (TB) research. However, there are limitations to using such databases for identifying patients with TB. To summarise validated methods for identifying TB in health administrative databases. We conducted a systematic literature search in two databases (Ovid Medline and Embase, January 1980-January 2016). We limited the search to diagnostic accuracy studies assessing algorithms derived from drug prescription, International Classification of Diseases (ICD) diagnostic code and/or laboratory data for identifying patients with TB in health administrative databases. The search identified 2413 unique citations. Of the 40 full-text articles reviewed, we included 14 in our review. Algorithms and diagnostic accuracy outcomes to identify TB varied widely across studies, with positive predictive value ranging from 1.3% to 100% and sensitivity ranging from 20% to 100%. Diagnostic accuracy measures of algorithms using out-patient, in-patient and/or laboratory data to identify patients with TB in health administrative databases vary widely across studies. Use solely of ICD diagnostic codes to identify TB, particularly when using out-patient records, is likely to lead to incorrect estimates of case numbers, given the current limitations of ICD systems in coding TB.

Disease management has been implemented for patients with asthma in various ways. We describe the approaches to and components of adult asthma disease-management interventions, examine the outcomes evaluated, and assess the quality of published studies. We searched the MEDLINE, EMBASE, CINAHL, PsychInfo, and Cochrane databases for studies published in 1986 through 2008, on adult asthma management. With the studies that met our inclusion criteria, we examined the clinical, process, medication, economic, and patient-reported outcomes reported, and the study designs, provider collaboration during the studies, and statistical methods. Twenty-nine articles describing 27 studies satisfied our inclusion criteria. There was great variation in the content, extent of collaboration between physician and non-physician providers responsible for intervention delivery, and outcomes examined across the 27 studies. Because of limitations in the design of 22 of the 27 studies, the differences in outcomes assessed, and the lack of rigorous statistical adjustment, we could not draw definitive conclusions about the effectiveness or cost-effectiveness of the asthma disease-management programs or which approach was most effective. Few well-designed studies with rigorous evaluations have been conducted to evaluate disease-management interventions for adults with asthma. Current evidence is insufficient to recommend any particular intervention.

To appraise the reporting quality of studies which concerned linezolid related thrombocytopenia referring to REporting of studies Conducted using Observational Routinely-collected health Data (RECORD) statement. Medline, Embase, Cochrane library and clinicaltrial.gov were searched for observational studies concerning linezolid related thrombocytopenia using routinely collected health data from 2000 to 2017. Two reviewers screened potential eligible articles and extracted data independently. Finally, reporting quality assessment was performed by two senior researchers using RECORD statement. Of 25 included studies, 11 (44.0%) mentioned the type of data in the title and/or abstract. In 38 items derived from RECORD statement, the median number of items reported in the included studies was 22 (interquartile range (IQR) 18 to 27). Inadequate reporting issues were discovered in the following aspects: validation studies of the codes or algorithms, study size estimation, quantitative variables, subgroup statistical methods, missing data, follow-up/matching or sampling strategy, sensitivity analysis and cleaning methods, funding and role of funders and accessibility of protocol, raw data. This study provides the evidence that the reporting quality of post-marketing safety evaluation studies conducted using routinely collected health data was often insufficient. Future stakeholders are encouraged to endorse the RECORD guidelines in pharmacovigilance.

Interprofessional education in primary health care for entry level students--A systematic literature review.

Kent, Fiona; Keating, Jennifer L

2015-12-01

This systematic review investigated student learning and patient outcomes associated with interprofessional education in outpatient, primary care clinics. Medline, Cinahl and Embase databases were searched to March 2014. A mixed method evaluation framework was applied to investigate the participants, interventions and effects on student learning and patient outcomes. 26 studies met the inclusion criteria; 13 were quantitative, predominately pre-post-survey design, 6 qualitative and 7 mixed methods design. Studies most commonly investigated student volunteers from medicine, nursing and allied health working in interprofessional clinics that were established to address gaps in community health care. Students appeared to learn teamwork skills and increase their knowledge of the roles of other disciplines. We found no convincing evidence that participation results in changes in attitudes towards other disciplines compared to single discipline education. We also found insufficient evidence to estimate the effectiveness of patient care delivered by interprofessional student teams in this setting compared to single discipline or no care. Given the logistical challenges associated with coordinating clinic attendance for interprofessional teams, high quality studies are needed to assess the effects of clinics on student learning and patient health outcomes.

The aim of this study is to provide the best available evidence on how to disinfect contact Goldman tonometers. A systematic review of all articles on disinfection of contact tonometers was conducted. Articles published up to July 2008 were identified in Medline, Embase and references from included articles. Two observers participated in the data retrieval and assessment of the studies identified. A total of 89 articles was retrieved, of which 58 could be included. Of those, 18 were clinical studies, 17 experimental microbiological studies, 8 expert assessments or guidelines and 15 reviews, surveys, descriptions of new methods. The clinical studies illustrate the importance of the problem, possible side effects of some disinfection methods but yield inconclusive results regarding efficacy. Experimental studies investigated a variety of bacterial and virological questions as well as material damage by disinfection. Both chlorine-based and hydrogen peroxide-based liquid disinfection were shown to be effective if applied for 5 min. Inconsistent results exist for alcohol wipes and UV disinfection - material damage has been described for both. The US guidelines and most expert recommendations are supported by evidence of the existing data. Chlorine-based and hydrogen peroxide-based liquid disinfections for 5 minutes are effective and relatively safe for disinfecting contact tonometers.

Introduction Colic in infants causes one in six families (17%) with children to consult a health professional. One systematic review of 15 community-based studies found a wide variation in prevalence, which depended on study design and method of recording. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical question: What are the effects of treatments for colic in infants? We searched: Medline, Embase, The Cochrane Library, and other important databases up to September 2009 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 27 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review we present information relating to the effectiveness and safety of the following interventions: advice to increase carrying, advice to reduce stimulation, casein hydrolysate milk, cranial osteopathy, crib vibrator device, focused counselling, gripe water, infant massage, low-lactose milk, simethicone, soya-based infant feeds, spinal manipulation, and whey hydrolysate milk.

Abstract Background: Atrial fibrillation (AF) is a most common cardiac arrhythmia in clinical practice. In China, Wenxin Keli (WXKL) therapy is a common treatment for AF, but its effects and safety remain uncertain. This protocol is to provide the methods used to assess the effectiveness and safety of WXKL for the treatment of patients with AF. Methods: We will search comprehensively the 4 English databases EMBASE, the Cochrane Central Register of Controlled Trials (Cochrane Library), PubMed, and Medline and 3 Chinese databases China National Knowledge Infrastructure (CNKI), Chinese Biomedical Literature Database (CBM), and Chinese Science and Technology Periodical database (VIP) on computer on March 2018 for the randomized controlled trials (RCTs) regarding WXKL for AF. The therapeutic effects according to the sinus rhythm and p-wave dispersion (Pwd) will be accepted as the primary outcomes. We will use RevMan V.5.3 software as well to compute the data synthesis carefully when a meta-analysis is allowed. Results: This study will provide a high-quality synthesis of current evidence of WXKL for AF. Conclusion: The conclusion of our systematic review will provide evidence to judge whether WXKL is an effective intervention for patient with AF.

To summarize and determine the appropriate use for the new and old management tools for genital warts. The following databases were searched: MEDLINE, PubMed, EMBASE, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, ACP Journal Club, and Trip. The bibliographies of retrieved papers were also reviewed. Clinical trials, qualitative review articles, consensus reports, and clinical practice guidelines were retrieved. Symptomatic warts are prevalent in at least 1% of the population between the ages of 15 and 49, with estimates of up to 50% of the population being infected with human papillomavirus at some point in their lifetime. Imiquimod and podophyllotoxin are 2 new treatments for external genital warts that are less painful and can be applied by patients at home. In addition, the quadrivalent human papillomavirus vaccine has been shown to be efficacious in preventing genital warts and cervical cancer. There is still a role for the older treatment methods in certain situations, such as intravaginal, urethral, anal, or recalcitrant warts; or for pregnant patients. The new treatments of external genital warts can reduce the pain of treatment and the number of office visits. Other treatment methods are still useful in certain situations.

To identify and clarify definitions and methods of measuring cancer-related cognitive impairment among prostate cancer patients treated with androgen deprivation therapy (ADT) and to assess the incidence and prevalence of cognitive impairment. A systematic review of Medline, EMBASE, PubMed, PsycINFO and CINAHL up to December 2015 was undertaken to identify English-language reviews. A total of 28 reviews were identified describing 20 primary studies. There were no studies of incidence. Reported prevalence rates varied between 10% and 69%. Cognitive domains impaired by ADT included: verbal memory, visuospatial ability and executive functions. Cognitive impairment was infrequently defined and four definitions were reported. A variety of measures and methods were used to assess cognitive function including neuropsychological tests, self-report measures and clinical assessments. The finding that, often, one measure was used to assess more than one aspect of cognition is likely to have contributed to imprecise estimates. There is a need to agree a definition of cognitive impairment in the clinical epidemiology of cancer and to standardise the selection of measures in order to aid accurate assessment and fair comparisons across studies regarding the prevalence of cognitive impairment among prostate cancer patients. © 2017 John Wiley & Sons Ltd.

Background Many research studies have been published on atopic eczema and these are often summarised in systematic reviews (SRs). Identifying SRs can be time-consuming for health professionals, and researchers. In order to facilitate the identification of important research, we have compiled an on-line resource that includes all relevant eczema reviews published since 2000. Methods SRs were searched for in MEDLINE (Ovid), EMBASE (Ovid), PubMed, the Cochrane Database of Systematic Reviews, DARE and NHS Evidence. Selected SRs were assessed against the pre-defined eligibility criteria and relevant articles were grouped by treatment category for the included interventions. All identified systematic reviews are included in the Global Resource of EczemA Trials (GREAT) database (www.greatdatabase.org.uk) and key clinical messages are summarised here. Results A total of 128 SRs reviews were identified, including three clinical guidelines. Of these, 46 (36%) were found in the Cochrane Library. No single database contained all of the SRs found. The number of SRs published per year has increased substantially over the last thirteen years, and reviews were published in a variety of clinical journals. Of the 128 SRs, 1 (1%) was on mechanism, 37 (29%) were on epidemiology, 40 (31%) were on eczema prevention, 29 (23%) were on topical treatments, 31 (24%) were on systemic treatments, and 24 (19%) were on other treatments. All SRs included searches of MEDLINE in their search methods. One hundred six SRs (83%) searched more than one electronic database. There were no language restrictions reported in the search methods of 52 of the SRs (41%). Conclusions This mapping of atopic eczema reviews is a valuable resource. It will help healthcare practitioners, guideline writers, information specialists, and researchers to quickly identify relevant up-to-date evidence in the field for improving patient care.

2015-12-01

It is uncertain whether external fixation or open reduction internal fixation (ORIF) is optimal for patients with bicondylar tibial plateau fractures. A systematic review using Ovid MEDLINE, Embase Classic, Embase, AMED, the Cochrane Library, Open Grey, Orthopaedic Proceedings, WHO International Clinical Trials Registry Platform, Current Controlled Trials, US National Institute for Health Trials Registry, and the Cochrane Central Register of Controlled Trials. The search was conducted on 3rd October 2014 and no language limits were applied. Inclusion criteria were all clinical study designs comparing external fixation with open reduction internal fixation of bicondylar tibial plateau fractures. Studies of only one treatment modality were excluded, as were those that included unicondylar tibial plateau fractures. Treatment effects from studies reporting dichotomous outcomes were summarised using odds ratios. Continuous outcomes were converted to standardized mean differences to assess the treatment effect, and inverse variance methods used to combine data. A fixed effect model was used for meta-analyses. Patients undergoing external fixation were more likely to have returned to preinjury activities by six and twelve months (P = 0.030) but not at 24 months follow-up. However, external fixation was complicated by a greater number of infections (OR 2.59, 95 % CI 1.25-5.36, P = 0.01). There were no statistically significant differences in the rates of deep infection, venous thromboembolism, compartment syndrome, or need for re-operation between the two groups. Although external fixation and ORIF are associated with different complication profiles, both are acceptable strategies for managing bicondylar tibial plateau fractures.

Objective In orthognathic surgery, antibiotics are prescribed to reduce the risk of postoperative infection. However, there is lack of consensus over the appropriate drug, the dose and duration of administration. The aim of this complex systematic review was to assess the effect of antibiotics on postoperative infections in orthognathic surgery. Methods Both systematic reviews and primary studies were assessed. Medline (OVID), The Cochrane Library (Wiley) and EMBASE (embase.com), PubMed (non-indexed articles) and Health Technology Assessment (HTA) publications were searched. The primary studies were assessed using GRADE and the systematic reviews by AMSTAR. Results Screening of abstracts yielded 6 systematic reviews and 36 primary studies warranting full text scrutiny. In total,14 primary studies were assessed for risk of bias. Assessment of the included systematic reviews identified two studies with a moderate risk of bias, due to inclusion in the meta-analyses of primary studies with a high risk of bias. Quality assessment of the primary studies disclosed one with a moderate risk of bias and one with a low risk. The former compared a single dose of antibiotic with 24 hour prophylaxis using the same antibiotic; the latter compared oral and intravenous administration of antibiotics. Given the limited number of acceptable studies, no statistical analysis was undertaken, as it was unlikely to contribute any relevant information. Conclusion With respect to antibiotic prophylaxis in orthognathic surgery, most of the studies to date have been poorly conducted and reported. Thus scientific uncertainty remains as to the preferred antibiotic and the optimal duration of administration. PMID:29385159

2018-06-01

Objectives Surgical repair of a tympanic membrane perforation is a common otologic procedure. However, achieving a successful closure can be challenging, especially if the anterior margin of the tympanic membrane is involved. The aim of this study was to systematically review the literature on evidence published in closure of anterior tympanic membrane perforations. Data Sources The following data sources were searched: Cochrane Central Register of Controlled Trials (1997 to August, 3 2017), MEDLINE (February 1948 to August 3, 2017), and Embase (1975 to August 3, 2017). Data Extraction Two authors independently reviewed titles and abstracts. The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines were followed. For the purpose of this study, the inclusion criteria were as follows; (1) studies reporting surgical technique for closure of anterior tympanic membrane perforations, (2) primary cases only, (3) articles published in the English language, (4) minimum 6-month follow-up, and (5) recorded pre- and postoperative audiometry. The exclusion criteria were non-English language articles, revision surgery, and no audiometric outcomes. Results On initial search, a total of 181 articles were identified (PubMed, n = 136; Cochrane, n = 28; Embase, n = 17). Based on the criteria, 136 articles were excluded. Full text of 45 articles was reviewed, and a further 24 articles were excluded. A total of 21 articles fulfilled the criteria for study inclusion. Conclusions All published evidence is level 4. High-quality controlled studies are required to determine the most effective method for closure of anterior tympanic membrane perforation.

To investigate the past and current status of teaching communication skills in undergraduate medical education and to review how medical education is progressing. A selective search was conducted of the literature that was published from 1960 to Jun 2008 in the MEDLINE, EMBASE, ERIC, Psychlnfo, and KMbase databases using "communication." All articles in 13 medical journals (including Academic Medicine, Medical Education, Teaching and Learning in Medicine, Medical Teacher, and Korean Journal of Medical Education) were reviewed. Each article was categorized according to 5 subjects (curriculum, methods, assessment, student factors, and research type). A total of 306 studies met the inclusion criteria for this study. Curriculum was the most frequent subject (n=85), followed by assessment (n=71), student factors (n=48), and methods (n=23). According to this research, the current trends of teaching communication skills in medical school are characterized by curriculum development,' 'blended-methods,' 'multisource assessment,' 'student attitudes,' and 'comparative studies' of education. It is time to figure it out optimistic ways to design a formal course. Now, 4 current trends in teaching and learning are emerging in communication skills. Curriculum development is stabilizing a variety of teaching methods are being adopted; a method of multisource assessment is being identified and the need to consider student attitudesis being recognized. In the near future, objective, comprehensive, and sophisticated evaluation is going to be the top priority in teaching communication skills with a variety of research types.

Physical therapy is a fast growing profession because of the aging population, medical advances, and the public's interest in health promotion. This study is part of the Medical Library Association (MLA) Nursing and Allied Health Resources Section's project to map the allied health literature. It identifies the core journals in physical therapy by analyzing the cited references of articles in two established physical therapy journals, Physical Therapy and Archives of Physical Medicine and Rehabilitation, during the period 1991 through 1993. This bibliometric analysis also determines the extent to which these journals are covered by the primary indexing sources, Allied and Alternative Medicine (AMED), the Cumulative Index to Nursing and Allied Health Literature, EMBASE, and MEDLINE. In this study, fourteen journals were found to supply one-third of all references studied. Ninety-five journals provided an additional third of the references. MEDLINE rated the highest as the indexing tool of choice for these 109 journals. The study results can assist in collection development decisions, advise physical therapists as to the best access to their core literature, and influence database producers to increase their coverage of the literature important to physical therapy.

2012-01-01

After being indexed in 2006 in EMBASE/Excerpta Medica and Scopus, and later in Science Citation Index Expanded and Journal Citation Reports/Science Edition citation databases, Biochemia Medica launched a new web page and online manuscript submission system in 2010, and celebrated its first Impact Factor in the same year. Now, starting from the end of the 2011, the journal will also be indexed in PubMed/Medline, and this will contribute to increase the journal’s exposure and accessibility worldwide. This is an important breakthrough, which is expected to further increase the popularity of the journal, as well as the submission rate and citations. Although several tools are currently available as Web resources to retrieve scientific articles, whose functioning and basic criteria are thought to be rather similar, the functionality, coverage, notoriety and prominence may differ widely. The recent indexing of Biochemia Medica in PubMed/Medline has thereby given us the opportunity to provide a timely update on biomedical research platforms, their relationship with article submissions and journal rankings.

Effective literature searching is particularly important for clinical practice guideline development. Sophisticated searching and filtering mechanisms are needed to help ensure that all relevant research is reviewed. To assess the methods used for the selection of evidence for guideline development by evidence-based guideline development organizations. A semistructured questionnaire assessing the databases, search filters and evaluation methods used for literature retrieval was distributed to eight major organizations involved in evidence-based guideline development. All of the organizations used search filters as part of guideline development. The medline database was the primary source accessed for literature retrieval. The OVID or SilverPlatter interfaces were used in preference to the freely accessed PubMed interface. The Cochrane Library, embase, cinahl and psycinfo databases were also frequently used by the organizations. All organizations reported the intention to improve and validate their filters for finding literature specifically relevant for guidelines. In the first international survey of its kind, eight major guideline development organizations indicated a strong interest in identifying, improving and standardizing search filters to improve guideline development. It is to be hoped that this will result in the standardization of, and open access to, search filters, an improvement in literature searching outcomes and greater collaboration among guideline development organizations.

2018-02-01

There is a need increase our understanding of what factors affect physical activity participation in children with intellectual disabilities (ID) and develop effective methods to overcome barriers and increase activity levels. This study aimed to systematically review parental perceptions of facilitators and barriers to physical activity for children with ID. A systematic search of Embase, Medline, ERIC, Web of Science, and PsycINFO was conducted (up to and including August, 2017) to identify relevant papers. A meta-ethnography approach was used to synthesise qualitative and quantitative results through the generation of third-order themes and a theoretical model. Ten studies were included, which ranged from weak to strong quality. Seventy-one second-order themes and 12 quantitative results were extracted. Five third-order themes were developed: family, child factors, inclusive programmes and facilities, social motivation, and child's experiences of physical activity. It is theorised that these factors can be facilitators or barriers to physical activity, depending on the information and education of relevant others, e.g. parents and coaches. Parents have an important role in supporting activity in children with ID. Increasing the information and education given to relevant others could be an important method of turning barriers into facilitators. Copyright © 2017 Elsevier Ltd. All rights reserved.

Fractional CO 2 has many indications in medicine including in treatment of acne scars and rejuvenation. The aim of this study was to evaluate the safety, efficacy, and cost-effectiveness of Fractional CO 2 Laser in comparison with other methods of rejuvenation and acne scar treatment. Several databases including Medline, OVID, EMBASE, CINHAL, SCOPUS, Web of science, CRD, and Cochrane were searched. After conducting the search and evaluation of selected publications, critical appraisal was done and eligible studies were accepted for inclusion in the systematic review. From 2667 identified publications two of the trials were eligible. The effectiveness and complications of Fractional CO 2 laser were comparable with Er:YAG but Fractional CO 2 laser was 14.7% (p = 0.01) more effective than Q-Switched ND:YAG laser. Cost affectivity of this method was the same as other alternative lasers. In conclusion Fractional CO 2 laser is an effective and safe method for curing of several kinds of skin diseases. Nevertheless there was not sufficient evidence to support its advantage. This device has equal or lower price in comparison to competent technologies except for the non- fractional ablative CO 2 laser that has the same or lower price and comparable effects.

Network meta-analyses (NMAs) aim to rank the benefits (or harms) of interventions, based on all available randomized controlled trials. Thus, the identification of relevant data is critical. We assessed the conduct of the literature searches in NMAs. Published NMAs were retrieved by searching electronic bibliographic databases and other sources. Two independent reviewers selected studies and five trained reviewers abstracted data regarding literature searches, in duplicate. Search method details were examined using descriptive statistics. Two hundred forty-nine NMAs were included. Eight used previous systematic reviews to identify primary studies without further searching, and five did not report any literature searches. In the 236 studies that used electronic databases to identify primary studies, the median number of databases was 3 (interquartile range: 3-5). MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials were the most commonly used databases. The most common supplemental search methods included reference lists of included studies (48%), reference lists of previous systematic reviews (40%), and clinical trial registries (32%). None of these supplemental methods was conducted in more than 50% of the NMAs. Literature searches in NMAs could be improved by searching more sources, and by involving a librarian or information specialist. Copyright © 2014 Elsevier Inc. All rights reserved.

Qualitative case study methodology in nursing research: an integrative review.

PubMed

Anthony, Susan; Jack, Susan

2009-06-01

This paper is a report of an integrative review conducted to critically analyse the contemporary use of qualitative case study methodology in nursing research. Increasing complexity in health care and increasing use of case study in nursing research support the need for current examination of this methodology. In 2007, a search for case study research (published 2005-2007) indexed in the CINAHL, MEDLINE, EMBASE, PsychINFO, Sociological Abstracts and SCOPUS databases was conducted. A sample of 42 case study research papers met the inclusion criteria. Whittemore and Knafl's integrative review method guided the analysis. Confusion exists about the name, nature and use of case study. This methodology, including terminology and concepts, is often invisible in qualitative study titles and abstracts. Case study is an exclusive methodology and an adjunct to exploring particular aspects of phenomena under investigation in larger or mixed-methods studies. A high quality of case study exists in nursing research. Judicious selection and diligent application of literature review methods promote the development of nursing science. Case study is becoming entrenched in the nursing research lexicon as a well-accepted methodology for studying phenomena in health and social care, and its growing use warrants continued appraisal to promote nursing knowledge development. Attention to all case study elements, process and publication is important in promoting authenticity, methodological quality and visibility.

How Do Urinary Calculi Influence Health-Related Quality of Life and Patient Treatment Preference: A Systematic Review.

Urinary stone disease is a common and often recurrent condition that can affect kidney function and requires a range of medical and surgical treatments, all of which can have a significant impact on patients' health-related quality of life (HRQoL) and treatment preferences. To review the literature systematically for all studies that include HRQoL measurement or patient preferences in the context of urinary stone disease. Ovid MEDLINE(R), Ovid MEDLINE(R) In-Process, EMBASE, SCOPUS, EconLit, and Web of Science were searched from inception to January 2016. All study designs with adult participants were included. Narrative synthesis was performed. Thirty-five studies met the inclusion criteria (six randomized controlled trials and 29 observational studies) from 15 countries, including 5472 patients. Eleven studies showed that stone formers had worse HRQoL than the general population; it was noted that stone formers were more likely to suffer from depression. Women have significantly lower HRQoL than men. Twenty-six studies used a generic HRQoL measure and six were nonvalidated disease specific. Studies concerning patient preference were heterogeneous and showed that extracorporeal shock wave lithotripsy is still favored above other interventions and that a large number of patients would prefer the treatment pathway to be decided upon by their clinician. Urinary calculi and its treatment can have significant negative patient impact and influence patient preferences. Patients with stone disease tend to have worse physical and mental HRQoL, quantified using generic measures. Structured research with disease-specific measures underpinned by sound methodology would be beneficial and aid in development of patient-centric management. This review was prospectively registered with the international prospective register of systematic reviews-PROSPERO 2013:CRD42013006084.

2016-06-01

Critiques of cost-effectiveness modelling in type 1 diabetes mellitus (T1DM) are scarce and are often undertaken in combination with type 2 diabetes mellitus (T2DM) models. However, T1DM is a separate disease, and it is therefore important to appraise modelling methods in T1DM. This review identified published economic models in T1DM and provided an overview of the characteristics and capabilities of available models, thus enabling a discussion of best-practice modelling approaches in T1DM. A systematic review of Embase(®), MEDLINE(®), MEDLINE(®) In-Process, and NHS EED was conducted to identify available models in T1DM. Key conferences and health technology assessment (HTA) websites were also reviewed. The characteristics of each model (e.g. model structure, simulation method, handling of uncertainty, incorporation of treatment effect, data for risk equations, and validation procedures, based on information in the primary publication) were extracted, with a focus on model capabilities. We identified 13 unique models. Overall, the included studies varied greatly in scope as well as in the quality and quantity of information reported, but six of the models (Archimedes, CDM [Core Diabetes Model], CRC DES [Cardiff Research Consortium Discrete Event Simulation], DCCT [Diabetes Control and Complications Trial], Sheffield, and EAGLE [Economic Assessment of Glycaemic control and Long-term Effects of diabetes]) were the most rigorous and thoroughly reported. Most models were Markov based, and cohort and microsimulation methods were equally common. All of the more comprehensive models employed microsimulation methods. Model structure varied widely, with the more holistic models providing a comprehensive approach to microvascular and macrovascular events, as well as including adverse events. The majority of studies reported a lifetime horizon, used a payer perspective, and had the capability for sensitivity analysis. Several models have been developed that provide useful insight into T1DM modelling. Based on a review of the models identified in this study, we identified a set of 'best in class' methods for the different technical aspects of T1DM modelling.

Atopic dermatitis, atopic eczema, or eczema? A systematic review, meta-analysis, and recommendation for uniform use of ‘atopic dermatitis’

2017-01-01

Background The lack of standardized nomenclature for atopic dermatitis (AD) creates unnecessary confusion for patients, healthcare providers, and researchers. It also negatively impacts accurate communication of research in the scientific literature. We sought to determine the most commonly used terms for AD. Methods A systematic review of the MEDLINE, EMBASE, and LILACS (1945–2016) for the terms AD, atopic eczema (AE), and multiple other eczematous disorders. Results In MEDLINE, 33 060 were identified, of which 21 299 (64.4%) publications used the term ‘AD’, 15 510 (46.9%) ‘eczema’, and only 2471 (7.5%) AE. Most of these publications used the term AD (82.0%) or eczema (70.8%) without additional nomenclature; only 1.2% used AE alone. Few publications used the terminology ‘childhood eczema’, ‘flexural eczema’, ‘infantile eczema’, ‘atopic neurodermatitis’, or ‘Besnier’s prurigo’. AD was rarely used until the late 1970s, after which it became the most commonly used of the three terms and continuously increased until 2015. Atopic eczema decreased between 2008 and 2015. Atopic dermatitis was the most commonly used term in studies across almost all publication types, languages, and journals. Conclusion Atopic dermatitis is the most commonly used term and appears to be increasing in popularity. Given that eczema is a nonspecific term that describes the morphological appearance of several forms of dermatitis, we strongly suggest the use of a more specific term, AD, in publications, healthcare clinician training, and patient education. Support from researchers, reviewers, and editors is key to success. PMID:27392131

Radiation Oncology in Undergraduate Medical Education: A Literature Review

Dennis, Kristopher E.B., E-mail: kdennis@bccancer.bc.c; Duncan, Graeme

2010-03-01

Purpose: To review the published literature pertaining to radiation oncology in undergraduate medical education. Methods and Materials: Ovid MEDLINE, Ovid MEDLINE Daily Update and EMBASE databases were searched for the 11-year period of January 1, 1998, through the last week of March 2009. A medical librarian used an extensive list of indexed subject headings and text words. Results: The search returned 640 article references, but only seven contained significant information pertaining to teaching radiation oncology to medical undergraduates. One article described a comprehensive oncology curriculum including recommended radiation oncology teaching objectives and sample student evaluations, two described integrating radiation oncologymore » teaching into a radiology rotation, two described multidisciplinary anatomy-based courses intended to reinforce principles of tumor biology and radiotherapy planning, one described an exercise designed to test clinical reasoning skills within radiation oncology cases, and one described a Web-based curriculum involving oncologic physics. Conclusions: To the authors' knowledge, this is the first review of the literature pertaining to teaching radiation oncology to medical undergraduates, and it demonstrates the paucity of published work in this area of medical education. Teaching radiation oncology should begin early in the undergraduate process, should be mandatory for all students, and should impart knowledge relevant to future general practitioners rather than detailed information relevant only to oncologists. Educators should make use of available model curricula and should integrate radiation oncology teaching into existing curricula or construct stand-alone oncology rotations where the principles of radiation oncology can be conveyed. Assessments of student knowledge and curriculum effectiveness are critical.« less

Abstract Objective To assess the impact on health-related outcomes, of group microfinance schemes based on collective empowerment. Methods We searched the databases Social Sciences Citation Index, Embase, MEDLINE, MEDLINE In-Process, PsycINFO, Social Policy & Practice and Conference Proceedings Citation Index for articles published between 1 January 1980 and 29 February 2016. Articles reporting on health impacts associated with group-based microfinance were included in a narrative synthesis. Findings We identified one cluster-randomized control trial and 22 quasi-experimental studies. All of the included interventions targeted poor women living in low- or middle-income countries. Some included a health-promotion component. The results of the higher quality studies indicated an association between membership of a microfinance scheme and improvements in the health of women and their children. The observed improvements included reduced maternal and infant mortality, better sexual health and, in some cases, lower levels of interpersonal violence. According to the results of the few studies in which changes in empowerment were measured, membership of the relatively large and well-established microfinance schemes generally led to increased empowerment but this did not necessarily translate into improved health outcomes. Qualitative evidence suggested that increased empowerment may have contributed to observed improvements in contraceptive use and mental well-being and reductions in the risk of violence from an intimate partner. Conclusion Membership of the larger, well-established group-based microfinance schemes is associated with improvements in some health outcomes. Future studies need to be designed to cope better with bias and to assess negative as well as positive social and health impacts. PMID:27708475

The limitations in performing functional activities in children and adolescents with cerebral palsy are important. The use of virtual reality systems is a new treatment approach that reinforces task-oriented motor learning. The purpose of this guide is to study the impact of the use of virtual reality systems in the improvement and acquisition of functional skills, and to evaluate the scientific evidence to determine the strength of recommendation of such interventions. All available full-text articles, regardless of their methodology, were included. The following data bases were consulted: PubMed (Medline), PEDro, EMBASE (OVID-Elsevier), Cochrane Library, Medline (OVID), CINAHL, ISI Web Knowledge. An assessment was made of methodological quality, the level of scientific evidence, and the strength of recommendations using the tools: Critical Review Form - Quantitative Studies and the Guidelines for Critical Review Form - Quantitative Studies and U.S. Preventive Services Task Force. Finally, we included 13 articles and 97 participants were recruited. We obtained significant improvements in outcome measures that assessed postural control and balance, upper limb function, the selective joint control, and gait. The guide has some limitations: the limited number of patients enrolled, clinical diversity and age range, as well as the methodological quality of existing trials. Virtual reality is a promising tool in the treatment of children with cerebral palsy. There is strong scientific evidence of an acceptable recommendation for the use of virtual reality systems in the treatment of cerebral palsy. Copyright © 2011 Sociedad Española de Neurología.

Randomised controlled trials (RCTs) are widely accepted as the preferred study design for evaluating healthcare interventions. When the sample size is determined, a (target) difference is typically specified that the RCT is designed to detect. This provides reassurance that the study will be informative, i.e., should such a difference exist, it is likely to be detected with the required statistical precision. The aim of this review was to identify potential methods for specifying the target difference in an RCT sample size calculation. A comprehensive systematic review of medical and non-medical literature was carried out for methods that could be used to specify the target difference for an RCT sample size calculation. The databases searched were MEDLINE, MEDLINE In-Process, EMBASE, the Cochrane Central Register of Controlled Trials, the Cochrane Methodology Register, PsycINFO, Science Citation Index, EconLit, the Education Resources Information Center (ERIC), and Scopus (for in-press publications); the search period was from 1966 or the earliest date covered, to between November 2010 and January 2011. Additionally, textbooks addressing the methodology of clinical trials and International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) tripartite guidelines for clinical trials were also consulted. A narrative synthesis of methods was produced. Studies that described a method that could be used for specifying an important and/or realistic difference were included. The search identified 11,485 potentially relevant articles from the databases searched. Of these, 1,434 were selected for full-text assessment, and a further nine were identified from other sources. Fifteen clinical trial textbooks and the ICH tripartite guidelines were also reviewed. In total, 777 studies were included, and within them, seven methods were identified-anchor, distribution, health economic, opinion-seeking, pilot study, review of the evidence base, and standardised effect size. A variety of methods are available that researchers can use for specifying the target difference in an RCT sample size calculation. Appropriate methods may vary depending on the aim (e.g., specifying an important difference versus a realistic difference), context (e.g., research question and availability of data), and underlying framework adopted (e.g., Bayesian versus conventional statistical approach). Guidance on the use of each method is given. No single method provides a perfect solution for all contexts.

Dehydration is an important cause of death in patients with Ebola virus disease (EVD). Parenteral fluids are often required in patients with fluid requirements in excess of their oral intake. The peripheral intravenous route is the most commonly used method of parenteral access, but inserting and maintaining an intravenous line can be challenging in the context of EVD. Therefore it is important to consider the advantages and disadvantages of different routes for achieving parenteral access (e.g. intravenous, intraosseous, subcutaneous and intraperitoneal). To compare the reliability, ease of use and speed of insertion of different parenteral access methods. We ran the search on 17 November 2014. We searched the Cochrane Injuries Group's Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library), Ovid MEDLINE(R) In-Process & Other Non-Indexed Citations, Ovid MEDLINE(R) Daily, Ovid MEDLINE(R) and Ovid OLDMEDLINE(R), Embase Classic + Embase (OvidSP), CINAHL (EBSCOhost), clinicaltrials.gov and screened reference lists. Randomised controlled trials comparing different parenteral routes for the infusion of fluids or medication. Two review authors examined the titles and abstracts of records obtained by searching the electronic databases to determine eligibility. Two review authors extracted data from the included trials and assessed the risk of bias. Outcome measures of interest were success of insertion; time required for insertion; number of insertion attempts; number of dislodgements; time period with functional access; local site reactions; clinicians' perception of ease of administration; needlestick injury to healthcare workers; patients' discomfort; and mortality. For trials involving the administration of fluids we also collected data on the volume of fluid infused, changes in serum electrolytes and markers of renal function. We rated the quality of the evidence as 'high', 'moderate', 'low' or 'very low' according to the GRADE approach for the following outcomes: success of insertion, time required for insertion, number of dislodgements, volume of fluid infused and needlestick injuries. We included 17 trials involving 885 participants. Parenteral access was used to infuse fluids in 11 trials and medications in six trials. None of the trials involved patients with EVD. Intravenous and intraosseous access was compared in four trials; intravenous and subcutaneous access in 11; peripheral intravenous and intraperitoneal access in one; saphenous vein cutdown and intraosseous access in one; and intraperitoneal with subcutaneous access in one. All of the trials assessing the intravenous method involved peripheral intravenous access.We judged few trials to be at low risk of bias for any of the assessed domains.Compared to the intraosseous group, patients in the intravenous group were more likely to experience an insertion failure (risk ratio (RR) 3.89, 95% confidence interval (CI) 2.39 to 6.33; n = 242; GRADE rating: low). We did not pool data for time to insertion but estimates from the trials suggest that inserting intravenous access takes longer (GRADE rating: moderate). Clinicians judged the intravenous route to be easier to insert (RR 0.15, 95% CI 0.04 to 0.61; n = 182). A larger volume of fluids was infused via the intravenous route (GRADE rating: moderate). There was no evidence of a difference between the two routes for any other outcomes, including adverse events.Compared to the subcutaneous group, patients in the intravenous group were more likely to experience an insertion failure (RR 14.79, 95% CI 2.87 to 76.08; n = 238; GRADE rating: moderate) and dislodgement of the device (RR 3.78, 95% CI 1.16 to 12.34; n = 67; GRADE rating: low). Clinicians also judged the intravenous route as being more difficult to insert and patients were more likely to be agitated in the intravenous group. Patients in the intravenous group were more likely to develop a local infection and phlebitis, but were less likely to develop erythema, oedema or swelling than those in the subcutaneous group. A larger volume of fluids was infused into patients via the intravenous route. There was no evidence of a difference between the two routes for any other outcome.There were insufficient data to reliably determine if the risk of insertion failure differed between the saphenous vein cutdown (SVC) and intraosseous method (RR 4.00, 95% CI 0.51 to 31.13; GRADE rating: low). Insertion using SVC took longer than the intraosseous method (MD 219.60 seconds, 95% CI 135.44 to 303.76; GRADE rating: moderate). There were no data and therefore there was no evidence of a difference between the two routes for any other outcome.There were insufficient data to reliably determine the relative effects of intraperitoneal or central intravenous access relative to any other parenteral access method. There are several different ways of achieving parenteral access in patients who are unable meet their fluid requirements with oral intake alone. The quality of the evidence, as assessed using the GRADE criteria, is somewhat limited because of the lack of adequately powered trials at low risk of bias. However, we believe that there is sufficient evidence to draw the following conclusions: if peripheral intravenous access can be achieved easily, this allows infusion of larger volumes of fluid than other routes; but if this is not possible, the intraosseous and subcutaneous routes are viable alternatives. The subcutaneous route may be suitable for patients who are not severely dehydrated but in whom ongoing fluid losses cannot be met by oral intake.A film to accompany this review can be viewed here (http://youtu.be/ArVPzkf93ng).

The use of telemedicine in psychiatry.

PubMed

Norman, S

2006-12-01

This paper examines the potential effects of using video-conferencing within the field of mental health in the UK. In order to assess the usefulness of telepsychiatric services, an electronic search was conducted for articles published between August 1998 and July 2006 using the MEDLINE, EMBASE, PsychINFO and Telemedicine and Information Exchange (TIE) databases. The search was carried out using the following terms: telepsychiatry, videoconferencing and telepsychology. A total of 178 articles were identified and based on review of the abstracts 72 were identified as being specific to efficacy, cost-effectiveness and satisfaction with psychiatric services delivered via videoconferencing. This paper concludes that the use of video conferencing can enhance psychiatric services within the UK especially for those patients who live in rural areas. Current advances in technology make this an increasingly more reliable and cost-effective method for assessing patients. The limitations of telemedicine are discussed and it is clear that this type of care is not suitable for all patients. Further research is required to assess the types of patients that telepsychiatry is most suitable for.

Home sleep apnea testing (HSAT) has increased due to improvements in technology, accessibility, and changes in third party reimbursement requirements. Research studies using HSAT have not consistently reported procedures and methodological challenges. This paper had two objectives: (1) summarize the literature on use of HSAT in research of adults and (2) identify methodological strategies to use in research and practice to standardize HSAT procedures and information. Search strategy included studies of participants undergoing sleep testing for OSA using HSAT. MEDLINE via PubMed, CINAHL, and Embase with the following search terms: "polysomnography," "home," "level III," "obstructive sleep apnea," and "out of center testing." Research articles that met inclusion criteria (n = 34) inconsistently reported methods and methodological challenges in terms of: (a) participant sampling; (b) instrumentation issues; (c) clinical variables; (d) data processing; and (e) patient acceptability. Ten methodological strategies were identified for adoption when using HSAT in research and practice. Future studies need to address the methodological challenges summarized in this paper as well as identify and report consistent HSAT procedures and information.

Introduction Around 15% to 30% of people are likely to have athlete's foot at any one time. The infection can spread to other parts of the body and to other people. Methods and outcomes We conducted a systematic overview, aiming to answer the following clinical question: What are the effects of oral treatments for athlete's foot? We searched: Medline, Embase, The Cochrane Library, and other important databases up to September 2014 (BMJ Clinical Evidence overviews are updated periodically; please check our website for the most up-to-date version of this overview). Results At this update, searching of electronic databases retrieved 335 studies. After deduplication and removal of conference abstracts, 210 records were screened for inclusion in the overview. Appraisal of titles and abstracts led to the exclusion of 162 studies and the further review of 48 full publications. Of the 48 full articles evaluated, one systematic review was included. We performed a GRADE evaluation for six PICO combinations. Conclusions In this systematic overview, we categorised the efficacy for one intervention based on information relating to the effectiveness and safety of oral antifungals versus placebo and different oral antifungals versus each other.

To determine the effect of adjunctive antithyroid drugs on the risk of treatment failure, hypothyroidism, and adverse events after radioiodine treatment. Meta-analysis. Electronic databases (Cochrane central register of controlled trials, Medline, Embase) searched to August 2006 and contact with experts. Review methods Three reviewers independently assessed trial eligibility and quality. Pooled relative risks for treatment failure and hypothyroidism after radioiodine treatment with and without adjunctive antithyroid drugs were calculated with a random effects model. We identified 14 relevant randomised controlled trials with a total of 1306 participants. Adjunctive antithyroid medication was associated with an increased risk of treatment failure (relative risk 1.28, 95% confidence interval 1.07 to 1.52; P=0.006) and a reduced risk for hypothyroidism (0.68, 0.53 to 0.87; P=0.006) after radioiodine treatment. We found no difference in summary estimates for the different antithyroid drugs or for whether antithyroid drugs were given before or after radioiodine treatment. Antithyroid drugs potentially increase rates of failure and reduce rates of hypothyroidism if they are given in the week before or after radioiodine treatment, respectively.

2015-12-12

This study explores the literature in establishing the value of undergraduate peer-based healthcare ethics teaching as an educational methodology. A narrative review of the literature concerning peer-based ethics teaching was conducted. MEDLINE, EMBASE, CINAHL, SCOPUS databases, and the Cochrane Library, were systematically searched for studies of peer-based ethics or professionalism teaching. Selected studies related peer-based teaching to ethics education outcomes. Ten publications were identified. Selected studies were varied in their chosen intervention methodology and analysis. Collectively, the identified studies suggest peer-based ethics education is an effective and valued educational methodology in training healthcare professionals. One paper suggests peer-based ethics teaching has advantages over traditional didactic methods. Peer-based ethics teaching also receives positive feedback from student participants. However, the limited literature base demonstrates a clear need for more evaluation of this pedagogy. The current literature base suggests that undergraduate peer based healthcare ethics teaching is valuable in terms of efficacy and student satisfaction. We conclude that the medical community should invest in further study in order to capitalise upon the potential of peer-based ethics teaching in undergraduate healthcare education.

Alkadhimi, Aslam; Al-Awadhi, Ebrahim A

2018-03-15

In recent years, extensive research has introduced novel ways of reinforcing orthodontic anchorage using a variety of devices temporarily anchored in bone (miniscrews). Currently, there are numerous manufacturers with different miniscrew designs on the market. The aim of this paper is to discuss the key design features of different miniscrew systems on the market. Furthermore, to present clinical selection criteria of miniscrews in different settings taking into account the determinant factors. Review of the literature was carried out using the following search methods: MEDLINE, EMBASE and the Cochrane Central Register of Controlled Trials (CENTRAL). The search was focused on studies published until January 2018. We studied each individual miniscrew from all the identified manufacturers in details. All the features were then summarised and presented as a clinical guideline for the selection of miniscrews. In this article, we reviewed the development of miniscrews and outlined the general design features of miniscrews as well as specific design features of the current miniscrews in the market. Extensive research of the current products was carried out to help clinicians better understand the difference between the various designs of miniscrews that can be used.

Leung, Doris G

2017-07-01

A growing body of the literature supports the use of magnetic resonance imaging as a potential biomarker for disease severity in the hereditary myopathies. We performed a systematic review of the medical literature to evaluate patterns of fat infiltration observed in magnetic resonance imaging studies of muscular dystrophy and congenital myopathy. Searches were performed using MEDLINE, EMBASE, and grey literature databases. Studies that described fat infiltration of muscles in patients with muscular dystrophy or congenital myopathy were selected for full-length review. Data on preferentially involved or spared muscles were extracted for analysis. A total of 2172 titles and abstracts were screened, and 70 publications met our criteria for inclusion in the systematic review. There were 23 distinct genetic disorders represented in this analysis. In most studies, preferential involvement and sparing of specific muscles were reported. We conclude that magnetic resonance imaging studies can be used to identify distinct patterns of muscle involvement in the hereditary myopathies. However, larger studies and standardized methods of reporting are needed to develop imaging as a diagnostic tool in these diseases.

Objective. To evaluate various noninvasive and minimally invasive procedures for the enhancement of orthodontic tooth movement in animals. Materials and Methods. Literature was searched using NCBI (PubMed, PubMed Central, and PubMed Health), MedPilot (Medline, Catalogue ZB MED, Catalogue Medicine Health, and Excerpta Medica Database (EMBASE)), and Google Scholar from January 2009 till 31 December 2014. We included original articles related to noninvasive and minimally invasive procedures to enhance orthodontic tooth movement in animals. Extraction of data and quality assessments were carried out by two observers independently. Results. The total number of hits was 9195 out of which just 11 fulfilled the inclusion criteria. Nine articles were good and 5 articles were moderate in quality. Low level laser therapy (LLLT) was among the most common noninvasive techniques whereas flapless corticision using various instruments was among the commonest minimally invasive procedures to enhance velocity of tooth movement. Conclusions. LLLT, low intensity pulsed ultrasound (LIPUS), mechanical vibration, and flapless corticision are emerging noninvasive and minimally invasive techniques which need further researches to establish protocols to use them clinically with conviction.

2017-01-01

Abstract Background Evidence has been systematically assessed comparing robotic with standard laparoscopy for treatment of endometrial cancer. Methods A search of Medline, Embase and Cochrane databases was performed until 30th October 2016. Results Thirty‐six papers including 33 retrospective studies, two matched case–control studies and one randomized controlled study were used in a meta‐analysis. Information from a further seven registry/database studies were assessed descriptively. There were no differences in the duration of surgery but days stay in hospital were shorter in the robotic arm (0.46 days, 95%CI 0.26 to 0.66). A robotic approach had less blood loss (57.74 mL, 95%CI 38.29 to 77.20), less conversions to laparotomy (RR = 0.41, 95%CI 0.29 to 0.59), and less overall complications (RR = 0.82, 95%CI 0.72 to 0.93). A robotic approach had higher costs ($1746.20, 95%CI $63.37 to $3429.03). Conclusion A robotic approach has favourable clinical outcomes but is more expensive. PMID:28762635

Objectives (1) Evaluate peer-reviewed publications regarding education in otolaryngology since 2000. (2) Analyze publication trends as compared with overall otolaryngology publications. Study Design Bibliometric analysis. Setting Academic medical center. Subjects and Methods A search for articles regarding education in otolaryngology from 2000 to 2015 was performed with MEDLINE and EMBASE databases, yielding 1220 articles; 362 relevant publications were categorized by topic, subspecialty, subject, article type, and funding source. Impact factors for each journal by year were obtained, and trends of each category over time were analyzed. These were then compared with publication numbers and impact factors for all otolaryngology journals. Results From 2000 to 2015, publications in otolaryngology education increased more rapidly than the field of otolaryngology overall. The most published topics included operative skills training, surgical simulation, and professionalism/career development. Recently there has been a decline in publications related to residency administration and duty hours relative to other topics. Only 12.2% of publications reported a funding source, and only 12.2% of studies were controlled. Conclusion Recent trends in otolaryngology literature reflect an increasing focus on education; however, this work is underfunded and often lacks high-quality evidence.

2017-01-01

Background The aim of this systematic literature review was to evaluate the feasibility of topical bisphosphonate application for preserving/enhancing alveolar bone in oral implantology. Material and Methods An electronic search was conducted in the PubMed/Medline, EMBASE, Scopus, Web of knowledge, and Google-Scholar databases for articles dated from January 2000 to December 2016. Two reviewers assessed the quality of the studies independently. Results A total of 154 abstracts were identified, of which 18 potentially relevant articles were selected; a final total of nine papers were included for analysis. Comparison of the findings of the selected studies was made difficult by the heterogeneity of the articles, all of them animal research papers that showed heterogeneity in the methodologies used and a high or moderate risk of bias. Conclusions The topical application of bisphosphonate solution would appear to favor new bone formation in alveolar defects, and boosts the regenerative capacities of biomaterials resulting in increased bone density. Key words:Alveolar bone, bone regeneration, topical application, biomaterial, bisphosphonates. PMID:28624840

Fever: Views in Anthroposophic Medicine and Their Scientific Validity

PubMed Central

2016-01-01

Objective. To conduct a scoping review to characterize how fever is viewed in anthroposophic medicine (AM) and discuss the scientific validity of these views. Methods. Systematic searches were run in Medline, Embase, CAMbase, and Google Scholar. Material from anthroposophic medical textbooks and articles was also used. Data was extracted and interpreted. Results. Most of the anthroposophic literature on this subject is in the German language. Anthroposophic physicians hold a beneficial view on fever, rarely suppress fever with antipyretics, and often use complementary means of alleviating discomfort. In AM, fever is considered to have the following potential benefits: promoting more complete recovery; preventing infection recurrences and atopic diseases; providing a unique opportunity for caregivers to provide loving care; facilitating individual development and resilience; protecting against cancer and boosting the anticancer effects of mistletoe products. These views are discussed with regard to the available scientific data. Conclusion. AM postulates that fever can be of short-term and long-term benefit in several ways; many of these opinions have become evidence-based (though still often not practiced) while others still need empirical studies to be validated, refuted, or modified.

2017-01-01

Abstract Background: Women consistently have higher sickness absence than men. The double-burden hypothesis suggests this is due to higher work–family burden in women than men. The current study aimed to systematically review prospective studies of work–family conflict and subsequent sickness absence. Methods: A systematic search was conducted in the electronic databases Medline, PsycINFO, and Embase with subject heading terms and keywords with no language or time restrictions. Two reviewers independently screened abstracts and read full-texts with pre-defined inclusion and exclusion criteria. Results: Eight included studies (n = 40 856 respondents) measure perceived work–family conflict and subsequent sickness absence. We found moderate evidence for a positive relationship between work–family conflict and subsequent sickness absence, and that women experience higher levels of work–family conflict than men. Conclusion: Work–family conflict is associated with later sickness absence, and work–family conflict is more common for women than for men. This indicates that work–family conflict may contribute to the gender gap in sick leave. However, further studies are needed to confirm whether this relationship is causal. PMID:28486653

Burning mouth syndrome

Introduction Burning mouth syndrome mainly affects women, particularly after the menopause, when its prevalence may be 18% to 33%. Methods and outcomes We conducted a systematic overview, aiming to answer the following clinical question: What are the effects of selected treatments for burning mouth syndrome? We searched: Medline, Embase, The Cochrane Library, and other important databases up to January 2015 (BMJ Clinical Evidence overviews are updated periodically; please check our website for the most up-to-date version of this overview). Results At this update, searching of electronic databases retrieved 70 studies. After deduplication and removal of conference abstracts, 45 records were screened for inclusion in the overview. Appraisal of titles and abstracts led to the exclusion of 25 studies and the further review of 20 full publications. Of the 20 full articles evaluated, one systematic review and nine RCTs were added at this update. We performed a GRADE evaluation for five PICO combinations. Conclusions In this systematic overview, we categorised the efficacy for six interventions based on information about the effectiveness and safety of alphalipoic acid, benzodiazepines, benzydamine hydrochloride, cognitive behavioural therapy (CBT), selective serotonin re-uptake inhibitors (SSRIs), and tricyclic antidepressants.

Benefits and harms of direct to consumer advertising: a systematic review

PubMed Central

Gilbody, S; Wilson, P; Watt, I

2005-01-01

Background: Direct to consumer advertising is increasingly used by the pharmaceutical industry, but its benefits and harms have yet to be summarised in a comprehensive and rigorous manner. Methods: A systematic review was conducted of robust evaluations of the impact (positive and negative) of direct to consumer advertising. A broad range of databases and data sources (including Cinahl, Embase, HMIC, HSRProj, Medline, PsycInfo, and the internet) were searched from inception to 2004. Results: From 2853 citations only four reports were found that met the strict inclusion criteria and provided usable results. Direct to consumer advertising is associated with increased prescription of advertised products and there is substantial impact on patients' request for specific drugs and physicians' confidence in prescribing. No additional benefits in terms of health outcomes were demonstrated. Discussion: Direct to consumer advertising is banned in most countries, and the research evidence tends to support the negative impact that is feared by those who support a legislative ban. Further research is needed into the clinical and economic impact of direct to consumer advertising in healthcare systems. PMID:16076787

What do people fear about cancer? A systematic review and meta‐synthesis of cancer fears in the general population

2016-01-01

Abstract Background Cancer has long inspired fear, but the effect of fear is not well understood; it seems both to facilitate and to deter early diagnosis behaviours. To elucidate fear's behavioural effects, we systematically reviewed and synthesised qualitative literature to explore what people fear about cancer. Methods We searched Medline, Embase, PsycInfo, Web of Science, AnthroSource, and Anthrobase for studies on cancer fear in breast, cervical, and colorectal cancer screening and analysed 102 studies from 26 countries using thematic synthesis. Results Fears of cancer emanated from a core view of cancer as a vicious, unpredictable, and indestructible enemy, evoking fears about its proximity, the (lack of) strategies to keep it at bay, the personal and social implications of succumbing, and fear of dying from cancer. Conclusions This view of cancer as ‘an enemy’ reprises the media's ‘war on cancer’ theme and may affect the acceptance of cancer early detection and prevention messages, since cancer's characteristics influenced whether ‘fight’ or ‘flight’ was considered appropriate.

Cardiovascular health, traffic-related air pollution and noise: are associations mutually confounded? A systematic review.

PubMed

Tétreault, Louis-François; Perron, Stéphane; Smargiassi, Audrey

2013-10-01

This review assessed the confounding effect of one traffic-related exposure (noise or air pollutants) on the association between the other exposure and cardiovascular outcomes. A systematic review was conducted with the databases Medline and Embase. The confounding effects in studies were assessed by using change in the estimate with a 10 % cutoff point. The influence on the change in the estimate of the quality of the studies, the exposure assessment methods and the correlation between road noise and air pollutions were also assessed. Nine publications were identified. For most studies, the specified confounders produced changes in estimates <10 %. The correlation between noise and pollutants, the quality of the study and of the exposure assessment do not seem to influence the confounding effects. Results from this review suggest that confounding of cardiovascular effects by noise or air pollutants is low, though with further improvements in exposure assessment, the situation may change. More studies using pollution indicators specific to road traffic are needed to properly assess if noise and air pollution are subjected to confounding.

2009-12-01

The best method for identifying the epidural space for neuraxial blocks is controversial. We conducted this meta-analysis to test the hypothesis that loss of resistance with liquid reduces complications with epidural placement. The MEDLINE, EMBASE, and Cochrane databases were searched for prospective, randomized studies comparing air versus liquid as the medium for loss of resistance during epidural space identification in adults. Data were abstracted from 5 studies (4 obstetric and 1 nonobstetric) (n = 4422 patients) that met inclusion criteria and analyzed for the following 6 outcomes: difficult catheter insertion, paresthesia, intravascular catheter insertion, accidental dural puncture, postdural puncture headache, and partial block. The overall risk differences for adverse outcome between the different mediums were not statistically different for the obstetric population. A small, but statistically significant, risk difference for postdural puncture headache was observed when fluid was used during epidural placement for chronic pain management. Larger studies that overcome limitations of heterogeneity across studies and a relatively infrequent occurrence of complications are required to determine the optimal medium for loss of resistance during epidural block.

Piezoelectric technology in otolaryngology, and head and neck surgery: a review.

PubMed

Meller, C; Havas, T E

2017-07-01

Piezoelectric technology has existed for many years as a surgical tool for precise removal of soft tissue and bone. The existing literature regarding its use specifically for otolaryngology, and head and neck surgery was reviewed. The databases Medline, the Cochrane Central Register of Controlled Trials, PubMed, Embase and Cambridge Scientific Abstracts were searched. Studies were selected and reviewed based on relevance. Sixty studies were identified and examined for evidence of benefits and disadvantages of piezoelectric surgery and its application in otolaryngology. The technique was compared with traditional surgical methods, in terms of intra-operative bleeding, histology, learning curve, operative time and post-operative pain. Piezoelectric technology has been successfully employed, particularly in otology and skull base surgery, where its specific advantages versus traditional drills include a lack of 'blunting' and tissue selectivity. Technical advantages include ease of use, a short learning curve and improved visibility. Its higher cost warrants consideration given that clinically significant improvements in operative time and morbidity have not yet been proven. Further studies may define the evolving role of piezoelectric surgery in otolaryngology, and head and neck surgery.

Return to sports after stress fractures of the tibial diaphysis: a systematic review.

Robertson, G A J; Wood, A M

2015-06-01

This review aims to provide information on the time taken to resume sport following tibial diaphyseal stress fractures (TDSFs). A systematic search of Medline, EMBASE, CINHAL, Cochrane, Web of Science, PEDro, Sports Discus, Scopus and Google Scholar was performed using the keywords 'tibial', 'tibia', 'stress', 'fractures', 'athletes', 'sports', 'non-operative', 'conservative', 'operative' and 'return to sport'. Twenty-seven studies were included: 16 reported specifically on anterior TDSFs and 5 on posterior TDSFs. The general principles were to primarily attempt non-operative management for all TDSFs and to consider operative intervention for anterior TDSFs that remained symptomatic after 3-6 months. Anterior TDSFs showed a prolonged return to sport. The best time to return to sport and the optimal management modalities for TDSFs remain undefined. Management of TDSFs should include a full assessment of training methods, equipment and diet to modify pre-disposing factors. Future prospective studies should aim to establish the optimal treatment modalities for TDSFs. © The Author 2015. Published by Oxford University Press. All rights reserved.

Middle-ear pain and trauma during air travel

PubMed Central

2015-01-01

Introduction Changes in air pressure during flying can cause ear-drum pain and perforation, vertigo, and hearing loss. It has been estimated that 10% of adults and 22% of children might have changes to the ear drum after a flight, although perforation is rare. Symptoms usually resolve spontaneously. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical question: What are the effects of interventions to prevent middle-ear pain during air travel? We searched: Medline, Embase, The Cochrane Library and other important databases up to July 2014 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found three studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review we present information relating to the effectiveness and safety of the following interventions: nasal balloon inflation, nasal decongestants (topical), and oral pseudoephedrine.

[Purpose] This review provides an evaluation of the evidence for the effectiveness of using manual therapy to treat cervicogenic dizziness. [Subjects and Methods] The literature was systematically searched on the May 2, 2016 using the following online databases: Medline, EMBASE, CINAHL and PEDro. This review included randomised controlled trials and compared the efficacy of manual therapy for the treatment of cervicogenic dizziness, compared to other types of intervention. This study measured changes based on dizziness intensity and frequency. [Results] The primary search found 30 articles, but only four articles met the inclusion criteria. Assessment of methodological quality was performed by two researchers using the PEDro scale. The level of evidence was determined using a recognised grading scale. Three out of the four articles were deemed to have high methodological quality, while the fourth was rated as moderate quality. The attributed level of evidence was moderate (level 2). [Conclusion] Manual therapy is potentially effective for managing cervicogenic dizziness. However, due to the heterogeneity of the results and techniques and the low number of studies, further research is recommended to provide conclusive evidence.

Exercise-induced biochemical changes and their potential influence on cancer: a scientific review

PubMed Central

Thomas, Robert James; Kenfield, Stacey A; Jimenez, Alfonso

2017-01-01

Aim To review and discuss the available international literature regarding the indirect and direct biochemical mechanisms that occur after exercise, which could positively, or negatively, influence oncogenic pathways. Methods The PubMed, MEDLINE, Embase and Cochrane libraries were searched for papers up to July 2016 addressing biochemical changes after exercise with a particular reference to cancer. The three authors independently assessed their appropriateness for inclusion in this review based on their scientific quality and relevance. Results 168 papers were selected and categorised into indirect and direct biochemical pathways. The indirect effects included changes in vitamin D, weight reduction, sunlight exposure and improved mood. The direct effects included insulin-like growth factor, epigenetic effects on gene expression and DNA repair, vasoactive intestinal peptide, oxidative stress and antioxidant pathways, heat shock proteins, testosterone, irisin, immunity, chronic inflammation and prostaglandins, energy metabolism and insulin resistance. Summary Exercise is one of several lifestyle factors known to lower the risk of developing cancer and is associated with lower relapse rates and better survival. This review highlights the numerous biochemical processes, which explain these potential anticancer benefits. PMID:27993842

One of the proposals for improving clinical practice is to introduce computerised decision support systems (CDSS) and integrate these with electronic medical records. Accordingly, this study sought to systematically review evidence on the effectiveness of CDSS in the management of depression. A search was performed in Medline, EMBASE and PsycInfo, in order to do this. The quality of quantitative studies was assessed using the SIGN method, and qualitative studies using the CASPe checklist. Seven studies were identified (3 randomised clinical trials, 3 non-randomised trials, and one qualitative study). The CDSS assessed incorporated content drawn from guidelines and other evidence-based products. In general, the CDSS had a positive impact on different aspects, such as the screening and diagnosis, treatment, improvement in depressive symptoms and quality of life, and referral of patients. The use of CDSS could thus serve to optimise care of depression in various scenarios by providing recommendations based on the best evidence available and facilitating decision-making in clinical practice.

2017-09-01

This rapid review summarizes best available evidence on consumers' needs and preferences for information about healthcare, with a focus on the Australian context. Three questions are addressed: 1) Where do consumers find and what platform do they use to access information about healthcare? 2) How do consumers use the healthcare information that they find? 3) About which topics or subjects do consumers need healthcare information? A hierarchical approach was adopted with evidence first sought from reviews then high quality studies using Medline (via PubMed), CINAHL, Embase, the JBI Database of Systematic Reviews and Implementation Reports, the Campbell Collaboration Library of Systematic Reviews, EPPI-Centre, and Epistemonikos. Twenty-eight articles were included; four systematic reviews, three literature reviews, thirteen quantitative studies, six qualitative studies, and two mixed methods studies. Consumers seek health information at varying times along the healthcare journey and through various modes of delivery. Complacency with historical health information modes is no longer appropriate and flexibility is essential to suit growing consumer demands. Health information should be readily available in different formats and not exclusive to any single medium. Copyright © 2017. Published by Elsevier B.V.

Background: This evidence-based guideline is an update of the 2005 American Academy of Neurology practice parameter on the treatment of essential tremor (ET). Methods: A literature review using MEDLINE, EMBASE, Science Citation Index, and CINAHL was performed to identify clinical trials in patients with ET published between 2004 and April 2010. Results and Recommendations: Conclusions and recommendations for the use of propranolol, primidone (Level A, established as effective); alprazolam, atenolol, gabapentin (monotherapy), sotalol, topiramate (Level B, probably effective); nadolol, nimodipine, clonazepam, botulinum toxin A, deep brain stimulation, thalamotomy (Level C, possibly effective); and gamma knife thalamotomy (Level U, insufficient evidence) are unchanged from the previous guideline. Changes to conclusions and recommendations from the previous guideline include the following: 1) levetiracetam and 3,4-diaminopyridine probably do not reduce limb tremor in ET and should not be considered (Level B); 2) flunarizine possibly has no effect in treating limb tremor in ET and may not be considered (Level C); and 3) there is insufficient evidence to support or refute the use of pregabalin, zonisamide, or clozapine as treatment for ET (Level U).

2008-01-01

Introduction Up to 80% of people with cancer experience pain at some time during their illness, and most will need opioid analgesics. This review assesses how different opioid analgesics compare, in terms of both pain control and adverse effects, in people with cancer. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical question: what are the effects of opioids in treating cancer-related pain? We searched: Medline, Embase, The Cochrane Library, and other important databases up to July 2007 (BMJ Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 22 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review, we present information relating to the effectiveness and safety of the following interventions: codeine, dihydrocodeine, transdermal fentanyl, hydromorphone, methadone, morphine, oxycodone, and tramadol.

2013-01-01

Background Medical data recording is one of the basic clinical tools. Electronic Health Record (EHR) is important for data processing, communication, efficiency and effectiveness of patients’ information access, confidentiality, ethical and/or legal issues. Clinical record promote and support communication among service providers and hence upscale quality of healthcare. Qualities of records are reflections of the quality of care patients offered. Methods Qualitative analysis was undertaken for this systematic review. We reviewed 40 materials Published from 1999 to 2013. We searched these materials from databases including ovidMEDLINE and ovidEMBASE. Two reviewers independently screened materials on medical data recording, documentation and information processing and communication. Finally, all selected references were summarized, reconciled and compiled as one compatible document. Result Patients were dying and/or getting much suffering as the result of poor quality medical records. Electronic health record minimizes errors, saves unnecessary time, and money wasted on processing medical data. Conclusion Many countries have been complaining for incompleteness, inappropriateness and illegibility of records. Therefore creating awareness on the magnitude of the problem has paramount importance. Hence available correct patient information has lots of potential in reducing errors and support roles.

[Purpose] To provide data for systematic intervention plans in occupational therapy practice by objectivity showing the value of mirror therapy interventions in children with cerebral palsy. [Subjects and Methods] Medline and EMBASE databases were searched for the key words "cerebral palsy," "mirror movement," "mirror therapy," and "mirror visual feedback." Nine studies that met the inclusion and exclusion criteria were identified. The qualitatively determined level of evidence, period of research, comparisons and interventions, tools used to measure the intervention, and the effects were analyzed. [Results] According to the results analyzed, one (1/9, 11.1%) study showed the same result as the control group, one (1/9, 11.1%) showed a negative effect, and seven (7/9, 77.8%) showed positive effects of mirror-mediated therapy, with meaningful improvement in function, such as hand strength, movement speed, muscle activity, and accuracy of hand matching. [Conclusion] Through this study, the value of mirror-mediated therapeutic interventions in occupational therapy practice targeting cerebral palsy was confirmed. It is expected that this result will be useful in establishing mirror therapy as an interventional program.

Theory of mind concerns the sociocognitive ability to infer others' thoughts. It has been theorized to be impaired in substance use and abuse, as its alterations might explain negative social and interpersonal outcomes noted in the course of disorders. In addition, the brain structures involved in Theory of Mind (ToM) have been found to be disrupted in drug use conditions. We undertook a systematic review of ToM functioning in drug use conditions. Four electronic databases (MEDLINE, Web of Science, PsycINFO, and Embase) were searched to find studies that have addressed ToM and conditions related to actual or previous drug use. The search found 147 papers, of which 14 fulfilled our review eligibility criteria. Different methods were used, but overall, results indicated that drugs are related to ToM deficits, particularly related to alcohol and amphetamines use. These impairments correlate with other clinical and cognitive functions. Despite the lack of studies and the methodological limitations of the existing ones Theory of Mind seems to play a role in drug use conditions, which requires further investigation.

To evaluate the inflammatory response following transvaginal implantation of polypropylene (PP) mesh. A comprehensive literature search was performed in the following databases from inception in April 2017: Ovid MEDLINE, Ovid EMBASE, and The Cochrane Library (Wiley). The studies retrieved were screened for eligibility against predefined inclusion and exclusion criteria. Twenty-three articles were included in this review. Following the implantation of PP mesh, there are immediate and local inflammatory responses. PP mesh elicits an inflammatory response that decreases over time; however, no studies documented a complete resolution. Further studies are needed to determine if there is a complete resolution of inflammation or if it persists. Copyright © 2017 Elsevier Inc. All rights reserved.

This ninth best‐practice review examines two series of common primary care questions in laboratory medicine: (i) potassium abnormalities and (ii) venous leg ulcer microbiology. The review is presented in question‐and‐answer format, referenced for each question series. The recommendations represent a précis of guidance found using a standardised literature search of national and international guidance notes, consensus statements, health policy documents and evidence‐based medicine reviews, supplemented by MEDLINE EMBASE searches to identify relevant primary research documents. They are not standards but form a guide to be set in the clinical context. Most are consensus rather than evidence‐based. They will be updated periodically to take account of new information.

Drug-drug interactions (DDIs) are one of the commonest causes of medication error in developed countries, particularly in the elderly due to poly-therapy, with a prevalence of 20-40%. In particular, poly-therapy increases the complexity of therapeutic management and thereby the risk of clinically important DDIs, which can both induce the development of adverse drug reactions or reduce the clinical efficacy. DDIs can be classify into two main groups: pharmacokinetic and pharmacodynamic. In this review, using Medline, PubMed, Embase, Cochrane library and Reference lists we searched articles published until June 30 2012, and we described the mechanism of pharmacokinetic DDIs focusing the interest on their clinical implications.

Nair, AS; Sahoo, RK

2016-01-01

Plantar fasciitis (PF) is a distressing condition experienced by many patients. Although self-limiting, it tends to become a chronic ailment if the precipitating factors are not addressed. One of the modality of treating PF is intra-lesional corticosteroid injection. This was done using palpation technique earlier but nowadays many specialists use ultrasound (US) imaging as a guide to give injection accurately instead of inadvertently damaging the plantar fascia or injecting into surrounding soft tissue, both of which can have serious implications. We did a literature search in Medline, Scopus, and Embase databases to find out articles describing US-guided corticosteroid injection for treating PF and whether guided injection was effective than injection given by palpation.

Mountain biking is a fast, exciting adventure sport with increasing numbers of participants and competitions. A search of PubMed, Medline, CINAHL, DH data, and Embase databases was performed using the following keywords: mountain, biking and injuries. This revealed 2 review articles, 17 case controlled studies, 4 case series and 5 case reports. This review summarises the published literature on mountain biking injuries, discusses injury frequency and common injury mechanisms. Riders are quick to adopt safety measures. Helmet usage is now increasingly common and handlebar adaptations have been discontinued. Although the sport has a reputation for speed and risk with research and awareness, injury prevention measures are being adopted making the sport as safe as possible.

Quality of life among dermatology patients: a systematic review of investigations using qualitative methods.

Quality of life may be assessed using quantitative or qualitative methods. Quantitative methods are commonly used in research settings; however, they may fail to capture the full range of patient experiences and impact on quality of life. Qualitative methods may be used to address this limitation. In this systematic review, we aim to synthesize data from articles utilizing qualitative methods to assess quality of life in dermatology patients. We performed a systematic review search using the MEDLINE, EMBASE, and SCOPUS databases. The search was conducted using the following search criteria: ("Dermatology" [MeSH]) AND ("Quality of Life" [MeSH]), AND ("Qualitative Research" [MeSH]), searching literature spanning from January 1, 1946- October 5, 2016. The systematic review of 15 articles included 533 dermatology patients. Patients expressed frustration over the unpredictability of disease symptoms and having to compensate for the subsequent limitations by altering their daily routines. Patients also reported profound helplessness due to chronic skin disease and social isolation in an effort to hide their disease. Patients noted the patient-provider relationship as a source of support and information exchange, with the goal to form easy to use treatment plans that met both physician and patient expectations. Qualitative assessment of patient quality of life can provide new insights into the patient experience and the impact of their skin disease. Qualitative methodology may capture meaningful information that may be overlooked by quantitative methods, and it should be included in quality of life research.

Kaplan-Meier survival analysis overestimates cumulative incidence in competing risks (CRs) settings. The extent of overestimation (or its clinical significance) has been questioned, and CRs methods are infrequently used. This meta-analysis compares the Kaplan-Meier method to the cumulative incidence function (CIF), a CRs method. We searched MEDLINE, EMBASE, BIOSIS Previews, Web of Science (1992-2016), and article bibliographies for studies estimating cumulative incidence using the Kaplan-Meier method and CIF. For studies with sufficient data, we calculated pooled risk ratios (RRs) comparing Kaplan-Meier and CIF estimates using DerSimonian and Laird random effects models. We performed stratified meta-analyses by clinical area, rate of CRs (CRs/events of interest), and follow-up time. Of 2,192 identified abstracts, we included 77 studies in the systematic review and meta-analyzed 55. The pooled RR demonstrated the Kaplan-Meier estimate was 1.41 [95% confidence interval (CI): 1.36, 1.47] times higher than the CIF. Overestimation was highest among studies with high rates of CRs [RR = 2.36 (95% CI: 1.79, 3.12)], studies related to hepatology [RR = 2.60 (95% CI: 2.12, 3.19)], and obstetrics and gynecology [RR = 1.84 (95% CI: 1.52, 2.23)]. The Kaplan-Meier method overestimated the cumulative incidence across 10 clinical areas. Using CRs methods will ensure accurate results inform clinical and policy decisions.

Coronary heart disease and household air pollution from use of solid fuel: a systematic review.

PubMed

Fatmi, Zafar; Coggon, David

2016-06-01

Evidence is emerging that indoor air pollution (IAP) from use of solid fuels for cooking and heating may be an important risk factor for coronary heart disease (CHD). We searched the Ovid Medline, Embase Classic, Embase and Web of Science databases from inception through to June 12, 2015, to identify reports of primary epidemiological research concerning the relationship of CHD to IAP from solid fuel, the likely magnitude of any increase in risk, and potential pathogenic mechanisms. The current balance of epidemiological evidence points to an increased risk of CHD from IAP as a consequence of using solid, and especially biomass, fuels for cooking and heating. Relative risks from long-term exposure could be 2- to 4-fold. The evidence base is still limited, and although an association of CHD with such IAP from solid fuel is consistent with the known hazards from smoking, environmental tobacco smoke and ambient air pollution, and supported by evidence of effects on inflammatory processes, atherosclerosis and blood pressure, it requires confirmation by larger and more robust studies. The completion of two relatively small case-control studies on CHD and IAP from use of biomass fuel demonstrates the feasibility of such research, and is an encouragement to further, larger studies using similar methods. The need for such research is particularly pressing because the incidence of CHD in developing countries is rising, and IAP may interact synergistically with the risk factors that are driving that increase. Furthermore, relatively cheap methods are available to reduce IAP from use of solid fuels, and there are indications from intervention studies that these may impact beneficially on CHD as well as other diseases caused by such pollution. © The Author 2016.

"Research protocol: a synthesis of qualitative studies on the process of adaptation to dependency in elderly persons and their families"

PubMed Central

2010-01-01

Background Dealing with dependency in the elderly and their families leads us to explore the life experience of those involved together with the processes of adaptation to this condition. A number of original studies have been published which, following a qualitative methodology, have dealt with both dimensions. Methods/Design Objectives: 1) To present a synthesis of the qualitative evidence available on the process of adaptation to dependency in elderly persons and their families; 2) to conduct an in-depth study into the experiences and strategies developed by both to optimise their living conditions; 3) to enable standards of action/intervention to be developed in the caregiving environment. A synthesis of qualitative studies is projected with an extensive and inclusive bibliography search strategy. The primary search will focus on the major databases (CINAHL, MEDLINE, EMBASE, PsycInfo, PSICODOC, Cochrane Library, JBI, EMBASE, LILACS, CUIDEN, CUIDEN qualitative, CUIDATGE, British Nursing Index, SSCI). The secondary search will be conducted in articles taken from the references to studies identified in the articles and reports and the manual search in congresses and foundation papers. Article quality will be assessed by the guide proposed by Sandelowski & Barroso and data extraction done using the QARI data extraction form proposed by the Joanna Briggs Institute for Evidence-Based Practice. The synthesis of the findings will be based on the principles and procedures of grounded theory: coding, identification and relationship between categories, and synthesis using constant comparison as a strategy. Discussion This synthesis of qualitative evidence will enable us to detect health needs as perceived by the receivers in their own interaction contexts. PMID:20738846

2017-11-01

To assess the methodological quality of systematic reviews (SRs) or meta-analysis concerning the predictive value of ERCC1 in platinum chemotherapy of non-small cell lung cancer. We searched the PubMed, EMbase, Cochrane library, international prospective register of systematic reviews, Chinese BioMedical Literature Database, China National Knowledge Infrastructure, Wan Fang and VIP database for SRs or meta-analysis. The methodological quality of included literatures was evaluated by risk of bias in systematic review (ROBIS) scale. Nineteen eligible SRs/meta-analysis were included. The most frequently searched databases were EMbase (74%), PubMed, Medline and CNKI. Fifteen SRs did additional retrieval manually, but none of them retrieved the registration platform. 47% described the two-reviewers model in the screening for eligible original articles, and seven SRs described the two reviewers to extract data. In methodological quality assessment, inter-rater reliability Kappa was 0.87 between two reviewers. Research question were well related to all SRs in phase 1 and the eligibility criteria was suitable for each SR, and rated as 'low' risk bias. But the 'high' risk bias existed in all the SRs regarding methods used to identify and/or select studies, and data collection and study appraisal. More than two-third of SRs or meta-analysis were finished with high risk of bias in the synthesis, findings and the final phase. The study demonstrated poor methodological quality of SRs/meta-analysis assessing the predictive value of ERCC1 in chemotherapy among the NSCLC patients, especially the high performance bias. Registration or publishing the protocol is recommended in future research.

To report epidemiology and characteristics of end-stage renal disease (ESRD) patients and renal transplant candidates, and to evaluate access to waiting list and results of renal transplantation. An exhaustive systematic review of the scientific literature was performed in the Medline database (http://www.ncbi.nlm.nih.gov) and Embase (http://www.embase.com) using different associations of the following keywords: "chronic kidney disease, epidemiology, kidney transplantation, cost, survival, graft, brain death, cardiac arrest, access, allocation". French legal documents have been reviewed using the government portal (http://www.legifrance.gouv.fr). Articles were selected according to methods, language of publication and relevance. The reference lists were used to identify additional historical studies of interest. Both prospective and retrospective series, in French and English, as well as review articles and recommendations were selected. In addition, French national transplant and health agencies (http://www.agence-biomedecine.fr and http://www.has-sante.fr) databases were screened using identical keywords. A total of 3234 articles, 6 official reports and 3 newspaper articles were identified; after careful selection 99 publications were eligible for our review. The increasing prevalence of chronic kidney disease (CKD) leads to worsen organ shortage. Renal transplantation remains the best treatment option for ESRD, providing recipients with an increased survival and quality of life, at lower costs than other renal replacement therapies. The never-ending lengthening of the waiting list raises issues regarding treatment strategies and candidates' selection, and underlines the limits of organ sharing without additional source of kidneys available for transplantation. Allocation policies aim to reduce medical or geographical disparities regarding enrollment on a waiting list or access to an allotransplant. Copyright © 2016 Elsevier Masson SAS.

To review epidemiologic data's and medical results of deceased donation in renal transplantation. Relevant publications were identified through Medline (http://www.ncbi.nlm.nih.gov) and Embase (http://www.embase.com) database using the following keywords, alone or in association, "brain death; cardiac arrest; deceased donation; organ procurement; transplantation". Articles were selected according to methods, language of publication and relevance. The reference lists were used to identify additional historical studies of interest. Both prospective and retrospective series, in French and English, as well as review articles and recommendations were selected. In addition, French national transplant and health agencies (http://www.agence-biomedecine.fr and http://www.has-sante.fr) databases were screened using identical keywords. A total of 2498 articles, 8 official reports and 17 newspaper articles were identified; after careful selection 157 publications were eligible for our review. Deceased donation may involve either brain death or non-heartbeating donors (NHBD). Organ shortage led to the procurement of organs from expanded-criteria donors, with an increased age at donation and extended vascular disease, leading to inferior results after transplantation and underlining the need for careful donor management during brain death or cardiac arrest. Evolution of French legislation covering bioethics allowed procurement from Maastricht categories II and recently III non-heartbeating donors. The increase of organ shortage emphasizes the need for a rigorous surgical technique during procurement to avoid loss of transplants. A history or current neoplasm in deceased-donors, requires attention to increase the pool of organs without putting the recipients at risk for cancer transmission. French NHBD program, especially from Maastricht category III, may stand for a potential source of valuable organs. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

Abstract Objective To formulate timely evidence-based guidelines for the management of opioid-induced bowel dysfunction. Setting Constipation is a major untoward effect of opioids. Increasing prescription of opioids has correlated to increased incidence of opioid-induced constipation. However, the inhibitory effects of opioids are not confined to the colon, but also affect higher segments of the gastrointestinal tract, leading to the coining of the term “opioid-induced bowel dysfunction.” Methods A literature search was conducted using Medline, EMBASE, and EMBASE Classic, and the Cochrane Central Register of Controlled Trials. Predefined search terms and inclusion/exclusion criteria were used to identify and categorize relevant papers. A series of statements were formulated and justified by a comment, then labeled with the degree of agreement and their level of evidence as judged by the Strength of Recommendation Taxonomy (SORT) system. Results From a list of 10,832 potentially relevant studies, 33 citations were identified for review. Screening the reference lists of the pertinent papers identified additional publications. Current definitions, prevalence, and mechanism of opioid-induced bowel dysfunction were reviewed, and a treatment algorithm and statements regarding patient management were developed to provide guidance on clinical best practice in the management of patients with opioid-induced constipation and opioid-induced bowel dysfunction. Conclusions In recent years, more insight has been gained in the pathophysiology of this “entity”; new treatment approaches have been developed, but guidelines on clinical best practice are still lacking. Current knowledge is insufficient regarding management of the opioid side effects on the upper gastrointestinal tract, but recommendations can be derived from what we know at present. PMID:28034973

This review sought to evaluate evidence addressing the following PICO question: (P) In schoolchildren, (I) what types of CPR, AED and first aid training (C) when compared to no training and to each other (O) lead to ability to perform life saving measures? Searches were conducted in Ovid MEDLINE (1946 - August 2012), Ovid EMBASE (1974 - August 2012) and Ebscohost Cinahl (1981 - August 2012). Database specific subject headings in all three databases (MeSH in MEDLINE, Emtree in EMBASE, Cinahl Headings) were selected for the concepts of cardiopulmonary resuscitation (CPR) and education. The combined results were then limited by age to include all school aged children. The search yielded 2620 articles. From titles, abstract and key words, 208 articles described CPR, AED and/or first aid training in schoolchildren and were eligible for review. These were obtained in full, were unavailable or not published in English. We reviewed articles for publication type and relevance. 48 studies were identified. One additional study was included as an extension of a study retrieved within the search. The studies found by the search were heterogeneous for study and training methodology. Findings regarding schoolchild age and physical factors, the role of practical training, use of self-instruction kits, use of computer based learning, reduced training time, trainer type, AED training are presented. Evidence shows that cardiopulmonary training, delivered in various ways, is successful in a wide age range of children. While older children perform more successfully on testing, younger children are able to perform basic tasks well, including use of AEDs. Chest compression depth correlates with physical factors such as increasing weight, BMI and height. Instruction must include hands on practice to enable children to perform physical tasks. Repeated training improves performance and retention but the format and frequency of repeated training is yet to be fully determined. Types of training that may reduce the main obstacles to implementation of such training in schools include use of self-instruction kits, computer based learning and use of teacher and peer tutor trainers, but again, need further exploration. As starting points we recommend legislative and funded mandates to provide such training to schoolchildren, and production and use of a framework which will delineate longitudinal delivery of training over the school career. Further research should have some uniformity in terms of assessment methodology, look at longer outcomes, and ideally will evaluate areas that are currently poorly defined. Copyright © 2013.

Objectives Forecasting can support rational decision-making around the introduction and use of emerging health technologies and prevent investment in technologies that have limited long-term potential. However, forecasting methods need to be credible. We performed a systematic search to identify the methods used in forecasting studies to predict future health technologies within a 3–20-year timeframe. Identification and retrospective assessment of such methods potentially offer a route to more reliable prediction. Design Systematic search of the literature to identify studies reported on methods of forecasting in healthcare. Participants People are not needed in this study. Data sources The authors searched MEDLINE, EMBASE, PsychINFO and grey literature sources, and included articles published in English that reported their methods and a list of identified technologies. Main outcome measure Studies reporting methods used to predict future health technologies within a 3–20-year timeframe with an identified list of individual healthcare technologies. Commercially sponsored reviews, long-term futurology studies (with over 20-year timeframes) and speculative editorials were excluded. Results 15 studies met our inclusion criteria. Our results showed that the majority of studies (13/15) consulted experts either alone or in combination with other methods such as literature searching. Only 2 studies used more complex forecasting tools such as scenario building. Conclusions The methodological fundamentals of formal 3–20-year prediction are consistent but vary in details. Further research needs to be conducted to ascertain if the predictions made were accurate and whether accuracy varies by the methods used or by the types of technologies identified. PMID:26966060

To describe/analyse a novel, community-based prenatal monitoring protocol for opioid-exposed pregnancies developed by our centre in 2014 to optimize prenatal care for this population. A literature review of published monitoring protocols for this population is also presented. Retrospective comparison of pre-protocol (n = 215) and post-protocol (n = 251) cohorts. Medline and Embase were searched between 2000-2016 using MeSH terms: [fetal monitoring OR prenatal care] AND [opioid-related disorders OR substance-related disorders] in Medline and [fetal monitoring OR prenatal care] AND [opiate addiction OR substance abuse] in Embase, producing 518 results. Thirteen studies included protocols for monitoring opioid-exposed pregnancies. No comprehensive monitoring protocols with high-quality supporting evidence were found. We evaluated 466 opioid-exposed pregnancies, 215 before and 251 after introduction of the protocol. Since implementation, there was a significant increase in the number of opioid-exposed patients who have underwent urine drug screening (72.6% to 89.2%, P < 0.0001); a significant reduction in the number of urine drug screenings positive for illicit opioids (50.2% to 29.1%, P < 0.0001); and a significant increase in the number of patients who discontinued illicit opioid use by the time of delivery (24.7% to 39.4%, P < 0.01). There was no difference in the CS rate (27.4% vs. 26.3%, P > 0.05). There were no observed differences in the rate of preterm birth, birth weight <2500 g, or Apgar score <7 (P > 0.05). Care of women with increased opioid use during pregnancy is an important but under-studied health issue. A novel protocol for focused antenatal care provision for women with opioid-exposed pregnancies improves standard of care and maternal/fetal outcomes. Copyright © 2017. Published by Elsevier Inc.

Risk of transmission of bovine spongiform encephalopathy to humans in the United States: report of the Council on Scientific Affairs. American Medical Association.

Tan, L; Williams, M A; Khan, M K; Champion, H C; Nielsen, N H

The risk of possible transmission of bovine spongiform encephalopathy (BSE) in the United States is a substantial public health concern. To systematically review the current scientific literature and discuss legislation and regulations that have been implemented to prevent the disease. Literature review using the MEDLINE, EMBASE, and Lexis/Nexis databases for 1975 through 1997 on the terms bovine spongiform encephalopathy, prion diseases, prions, and Creutzfeldt-Jakob syndrome. The Internet was used to identify regulatory actions and health surveillance. MEDLINE, EMBASE, and Lexis/Nexis databases were searched from 1975 through 1997 for English-language articles that provided information on assessment of transmission risk. Unique circumstances in the United Kingdom caused the emergence and propagation of BSE in cattle, including widespread use of meat and bonemeal cattle feed derived from scrapie-infected sheep and the adoption of a new type of processing that did not reduce the amount of infectious prions prior to feeding. Many of these circumstances do not exist in the United States. In the United Kingdom, new variant Creutzfeldt-Jakob disease probably resulted from the ingestion of BSE-contaminated processed beef. The United Kingdom and the European Union now have strong regulations in place to stop the spread of BSE. While BSE has not been observed in the United States, the US government has surveillance and response plans in effect. Current risk of transmission of BSE in the United States is minimal because (1) BSE has not been shown to exist in this country; (2) adequate regulations exist to prevent entry of foreign sources of BSE into the United States; (3) adequate regulations exist to prevent undetected cases of BSE from uncontrolled amplification within the US cattle population; and (4) adequate preventive guidelines exist to prevent high-risk bovine materials from contaminating products intended for human consumption.

To determine the incidence of internal hernias after laparoscopic colorectal surgery and evaluate the risk factors and strategies in the management of this serious complication. Two databases (MEDLINE from 1946 and Embase from 1949) were searched to mid-September 2015. The search terms included volvulus or internal hernia and laparoscopic colorectal surgery or colorectal surgery or anterior resection or laparoscopic colectomy. We found 49 and 124 articles on MEDLINE and Embase, respectively, an additional 15 articles were found on reviewing the references. After removal of duplicates, 176 abstracts were reviewed, with 33 full texts reviewed and 15 eligible for qualitative synthesis. The incidence of internal hernia after laparoscopic colorectal surgery is low (0.65%). Thirty-one patients were identified. Five cases were from two prospective studies (5/648, 0.8%), 20 cases were from seven retrospective studies (20/3165, 0.6%) and six patients were from case reports. Of the 31 identified cases, 21 were associated with left-sided resection, four with right sided resection, two with transverse colectomy, one with a subtotal colectomy and in three cases the operation was not specified. The majority of cases (64.3%) were associated with a restorative left sided resection. Nearly all cases occurred within 4 months of surgery. All patients required re-operation and reduction of the internal hernia and 35.7% of cases required a bowel resection. In 52.2% of cases, the mesenteric defect was closed at the second operation and 52.6% of cases were successfully managed laparoscopically. There were three deaths (0.08%). Mesenteric hernias are a rare but important complication of laparoscopic colorectal surgery. The evidence does not support routine closure for all cases, but selective closure of the mesenteric defect during left-sided restorative procedures in high-risk patients at the initial surgery may be considered.

This meta-analysis aimed to evaluate the efficiency and safety of tranexamic acid for reducing blood loss and transfusion requirements in patients undergoing total shoulder arthroplasty. A systematic search was performed in Embase (1980-2017.04, embase.com), Medline (1966-2017.04, medline.com), PubMed (1966-2017.04, pubmed.com), ScienceDirect (1985-2017.04, sciencedirect.com), and Web of Science (1950-2017.04, webofknowledge.com). Study which assessed the efficiency and safety of tranexamic acid in total shoulder arthroplasty was selected. Meta-analysis was performed using Stata 11.0 software. In all, 484 patients from 2 randomized controlled trials (RCTs) and 2 non-RCTs were subjected to meta-analysis. The present meta-analysis demonstrated that there was less total blood loss (mean difference [MD] -172.16, 95% confidence interval [CI] -35.46 to -308.87, P = .01, d = 0.33) and transfusion rate (odds ratio 0.34, 95% CI 0.13 to 0.91, P = .03, d = 0.29) in tranexamic acid groups compared with the control groups. There were no significant differences in duration of surgery (MD 0.02, 95% CI -0.12 to 0.22, P = .89, d = 0.19), length of stay (MD -0.06, 95% CI -0.26 to 0.14, P = .56, d = 0.20), or incidence of adverse effects such as deep venous thrombosis (odds ratio 1.15, 95% CI 0.33 to 4.00, P = .83, d = 0.53). Clinical application of tranexamic acid seemed to result in significant reductions in total blood loss, hemoglobin decline and transfusion requirements following total shoulder arthroplasty. Moreover, no increased risk of the thrombotic events was identified. Due to the limited quality of the evidence currently available, higher quality RCTs are required.

The aim of this study was to report on a mixed methods systematic review that critically examines the evidence for mentorship in nursing academia. Nursing education institutions globally have issued calls for mentorship. There is emerging evidence to support the value of mentorship in other disciplines, but the extant state of the evidence in nursing academia is not known. A comprehensive review of the evidence is required. A mixed methods systematic review. Five databases (MEDLINE, CINAHL, EMBASE, ERIC, PsycINFO) were searched using an a priori search strategy from inception to 2 November 2015 to identify quantitative, qualitative and mixed methods studies. Grey literature searches were also conducted in electronic databases (ProQuest Dissertations and Theses, Index to Theses) and mentorship conference proceedings and by hand searching the reference lists of eligible studies. Study quality was assessed prior to inclusion using standardized critical appraisal instruments from the Joanna Briggs Institute. A convergent qualitative synthesis design was used where results from qualitative, quantitative and mixed methods studies were transformed into qualitative findings. Mentorship outcomes were mapped to a theory-informed framework. Thirty-four studies were included in this review, from the 3001 records initially retrieved. In general, mentorship had a positive impact on behavioural, career, attitudinal, relational and motivational outcomes; however, the methodological quality of studies was weak. This review can inform the objectives of mentorship interventions and contribute to a more rigorous approach to studies that assess mentorship outcomes. © 2016 John Wiley & Sons Ltd.

Physiotherapy for patients with soft tissue shoulder disorders: a systematic review of randomised clinical trials.

OBJECTIVE: To assess the effectiveness of physiotherapy for patients with soft tissue shoulder disorders. DESIGN: A systematic computerised literature search of Medline and Embase, supplemented with citation tracking, for relevant trials with random allocation published before 1996. SUBJECTS: Patients treated with physiotherapy for disorders of soft tissue of the shoulder. MAIN OUTCOME MEASURES: Success rates, mobility, pain, functional status. RESULTS: Six of the 20 assessed trials satisfied at least five of eight validity criteria. Assessment of methods was often hampered by insufficient information on various validity criteria, and trials were often flawed by lack of blinding, high proportions of withdrawals from treatment, and high proportions of missing values. Trial sizes were small: only six trials included intervention groups of more than 25 patients. Ultrasound therapy, evaluated in six trials, was not shown to be effective. Four other trials favoured physiotherapy (laser therapy or manipulation), but the validity of their methods was unsatisfactory. CONCLUSIONS: There is evidence that ultrasound therapy is ineffective in the treatment of soft tissue shoulder disorders. Due to small trial sizes and unsatisfactory methods, evidence for the effectiveness of other methods of physiotherapy is inconclusive. For all methods of treatment, trials were too heterogeneous with respect to included patients, index and reference treatments, and follow up to merit valid statistical pooling. Future studies should show whether physiotherapy is superior to treatment with drugs, steroid injections, or a wait and see policy. PMID:9233322

With Clostridium difficile infection (CDI) on the rise, knowledge of the current economic burden of CDI can inform decisions on interventions related to CDI. We systematically reviewed CDI cost-of-illness (COI) studies. We performed literature searches in six databases: MEDLINE, Embase, the Health Technology Assessment Database, the National Health Service Economic Evaluation Database, the Cost-Effectiveness Analysis Registry, and EconLit. We also searched gray literature and conducted reference list searches. Two reviewers screened articles independently. One reviewer abstracted data and assessed quality using a modified guideline for economic evaluations. The second reviewer validated the abstraction and assessment. We identified 45 COI studies between 1988 and June 2014. Most (84%) of the studies were from the United States, calculating costs of hospital stays (87%), and focusing on direct costs (100%). Attributable mean CDI costs ranged from $8,911 to $30,049 for hospitalized patients. Few studies stated resource quantification methods (0%), an epidemiological approach (0%), or a justified study perspective (16%) in their cost analyses. In addition, few studies conducted sensitivity analyses (7%). Forty-five COI studies quantified and confirmed the economic impact of CDI. Costing methods across studies were heterogeneous. Future studies should follow standard COI methodology, expand study perspectives (e.g., patient), and explore populations least studied (e.g., community-acquired CDI).

Evidence-based outcomes following inferior alveolar and lingual nerve injury and repair: a systematic review.

Kushnerev, E; Yates, J M

2015-10-01

The inferior alveolar nerve (IAN) and lingual (LN) are susceptible to iatrogenic surgical damage. Systematically review recent clinical evidence regarding IAN/LN repair methods and to develop updated guidelines for managing injury. Recent publications on IAN/LN microsurgical repair from Medline, Embase and Cochrane Library databases were screened by title/abstract. Main texts were appraised for exclusion criteria: no treatment performed or results provided, poor/lacking procedural description, cohort <3 patients. Of 366 retrieved papers, 27 were suitable for final analysis. Treatment type for injured IANs/LNs depended on injury type, injury timing, neurosensory disturbances and intra-operative findings. Best functional nerve recovery occurred after direct apposition and suturing if nerve ending gaps were <10 mm; larger gaps required nerve grafting (sural/greater auricular nerve). Timing of microneurosurgical repair after injury remains debated. Most authors recommend surgery when neurosensory deficit shows no improvement 90 days post-diagnosis. Nerve transection diagnosed intra-operatively should be repaired in situ; minor nerve injury repair can be delayed. No consensus exists regarding optimal methods and timing for IAN/LN repair. We suggest a schematic guideline for treating IAN/LN injury, based on the most current evidence. We acknowledge that additional RCTs are required to provide definitive confirmation of optimal treatment approaches. © 2015 John Wiley & Sons Ltd.

Ear wax

2008-01-01

Introduction Ear wax only becomes a problem if it causes a hearing impairment or other ear-related symptoms. Ear wax is more likely to accumulate and cause a hearing impairment when normal extrusion is prevented — for example, by the use of hearing aids, or by the use of cotton buds to clean the ears. Ear wax can visually obscure the ear drum, and may need to be removed for diagnostic purposes. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical question: What are the effects of methods to remove ear wax? We searched: Medline, Embase, The Cochrane Library, and other important databases up to June 2007 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found nine systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review, we present information relating to the effectiveness and safety of the following interventions: ear syringing; manual removal (other than ear syringing); and wax softeners (alone or prior to syringing).

2018-01-01

Background Teamwork in the operating theatre is becoming increasingly recognized as a major factor in clinical outcomes. Many tools have been developed to measure teamwork. Most fall into two categories: self‐assessment by theatre staff and assessment by observers. A critical and comparative analysis of the validity and reliability of these tools is lacking. Methods MEDLINE and Embase databases were searched following PRISMA guidelines. Content validity was assessed using measurements of inter‐rater agreement, predictive validity and multisite reliability, and interobserver reliability using statistical measures of inter‐rater agreement and reliability. Quantitative meta‐analysis was deemed unsuitable. Results Forty‐eight articles were selected for final inclusion; self‐assessment tools were used in 18 and observational tools in 28, and there were two qualitative studies. Self‐assessment of teamwork by profession varied with the profession of the assessor. The most robust self‐assessment tool was the Safety Attitudes Questionnaire (SAQ), although this failed to demonstrate multisite reliability. The most robust observational tool was the Non‐Technical Skills (NOTECHS) system, which demonstrated both test–retest reliability (P > 0·09) and interobserver reliability (Rwg = 0·96). Conclusion Self‐assessment of teamwork by the theatre team was influenced by professional differences. Observational tools, when used by trained observers, circumvented this.

A systematic review of dydrogesterone for the treatment of threatened miscarriage

PubMed Central

2012-01-01

The objective of this systematic review was to assess whether the orally acting progestagen, dydrogesterone lowers the incidence of miscarriage in women with threatened miscarriage. A computerized search was performed in Medline, Embase, and Ovid Medline for original reports with the product name ‘Duphaston’ or ‘dydrogesterone’, and limited to clinical human data. Twenty-one reports of dydrogesterone treatment were identified with 1380 patients. Five randomized trials were identified, including 660 women who fulfilled the criteria for metaanalysis. The number of subsequent miscarriages or continuing pregnancies per randomized woman was compared in women receiving dydrogesterone compared to standard bed rest or placebo intervention. There was a 13% (44/335) miscarriage rate after dydrogesterone administration compared to 24% in control women [odds ratio for miscarriage 0.47, (CI = 0.31–0.7), 11% absolute reduction in the miscarriage rate]. The adverse and side effects were summarized in all 21 reports, and seemed to be minimal. Although all the predictive and confounding factors could not be controlled for, the results of this systematic review show a significant reduction of 47% in the odds for miscarriage when dydrogesterone is compared to standard care indicating a real treatment effect.

2007-01-01

This study sought to identify and compare various practical and current approaches of health technology assessment (HTA) priority setting. A literature search was performed across PubMed, MEDLINE, EMBASE, BIOSIS, and Cochrane. Given an earlier review conducted by European agencies (EUR-ASSESS project), the search was limited to literature indexed from 1996 onward. We also searched Web sites of HTA agencies as well as HTAi and ISTAHC conference abstracts. Agency representatives were contacted for information about their priority-setting processes. Reports on practical approaches selected through these sources were identified independently by two reviewers. A total of twelve current priority-setting frameworks from eleven agencies were identified. Ten countries were represented: Canada, Denmark, England, Hungary, Israel, Scotland, Spain, Sweden, The Netherlands, and United States. Fifty-nine unique HTA priority-setting criteria were divided into eleven categories (alternatives; budget impact; clinical impact; controversial nature of proposed technology; disease burden; economic impact; ethical, legal, or psychosocial implications; evidence; interest; timeliness of review; variation in rates of use). Differences across HTA agencies were found regarding procedures for categorizing, scoring, and weighing of policy criteria. Variability exists in the methods for priority setting of health technology assessment across HTA agencies. Quantitative rating methods and consideration of cost benefit for priority setting were seldom used. These study results will assist HTA agencies that are re-visiting or developing their prioritization methods.

Evaluation of electrical impedance ratio measurements in accuracy of electronic apex locators.

2015-05-01

The aim of this paper was evaluating the ratios of electrical impedance measurements reported in previous studies through a correlation analysis in order to explicit it as the contributing factor to the accuracy of electronic apex locator (EAL). The literature regarding electrical property measurements of EALs was screened using Medline and Embase. All data acquired were plotted to identify correlations between impedance and log-scaled frequency. The accuracy of the impedance ratio method used to detect the apical constriction (APC) in most EALs was evaluated using linear ramp function fitting. Changes of impedance ratios for various frequencies were evaluated for a variety of file positions. Among the ten papers selected in the search process, the first-order equations between log-scaled frequency and impedance were in the negative direction. When the model for the ratios was assumed to be a linear ramp function, the ratio values decreased if the file went deeper and the average ratio values of the left and right horizontal zones were significantly different in 8 out of 9 studies. The APC was located within the interval of linear relation between the left and right horizontal zones of the linear ramp model. Using the ratio method, the APC was located within a linear interval. Therefore, using the impedance ratio between electrical impedance measurements at different frequencies was a robust method for detection of the APC.

2014-01-01

Background Amyotrophic lateral sclerosis (ALS) is relatively rare, yet the economic and social burden is substantial. Having accurate incidence and prevalence estimates would facilitate efficient allocation of healthcare resources. Objective To provide a comprehensive and critical review of the epidemiologic literature on ALS. Methods MEDLINE and EMBASE (1995–2011) databases of population-based studies on ALS incidence and prevalence reporting quantitative data were analyzed. Data extracted included study location and time, design and data sources, case ascertainment methods, and incidence and/or prevalence rates. Medians and inter-quartile ranges (IQRs) were calculated, and ALS case estimates derived using 2010 population estimates. Results In all, 37 articles met inclusion criteria. In Europe, the median (IQR) incidence rate (/100,000 population) was 2.08 (1.47–2.43), corresponding to an estimated 15,355 (10,852–17,938) cases. Median (IQR) prevalence (/100,000 population) was 5.40 (4.06–7.89), or 39,863 (29,971–58,244) prevalent cases. Conclusions Disparity in rates among ALS incidence and prevalence studies may be due to differences in study design or true variations in population demographics, such as age, and geography, including environmental factors and genetic predisposition. Additional large-scale studies that use standardized case ascertainment methods are needed to more accurately assess the true global burden of ALS. PMID:23860588

2016-01-01

Objective: There are a number of published data indicating in vitro anti-HSV activity of some of Iranian herbal extracts with no systematic review to discuss these results. Therefore, this article was aimed to review and discuss the methods carried out and the phytochemistry and bioactivity of the extracts used and also conclusions provided in these publications. Materials and Methods: Published articles both in English (from Medline, Science Direct, EMBASE, Scopus, Pro Quest, Google scholar, Cochrane Library) and in Persian (from SID, Iran Medex and Magiran) databases, from 1966 to October 2014 were incorporated in this review. The in vitro studies that lacked CC50, IC50, were excluded. Results: Only 42 published reports were found to examine Iranian herbs against HSV replication in vitro. Seventeen out of 42 studies in which 23 kinds of medicinal plants were subjected to crude extraction were included. The review of data showed that some of the herbal extracts including Hyssopus officinalis methanolic extract, Melissa officinalis aqueous extract, Quercus persica L. hydroalcoholic extract and Securigeras ecuridaca methanolic extract with selective index (SI) of 234, 877, >778 and 250, respectively were highly effective against HSV in vitro. Conclusion: More comprehensive studies using more advanced methods are needed to be done to achieve promising anti-HSV agents from the bioactive compounds isolated from these herbs. PMID:27761420

Methods to elicit probability distributions from experts: a systematic review of reported practice in health technology assessment.

Grigore, Bogdan; Peters, Jaime; Hyde, Christopher; Stein, Ken

2013-11-01

Elicitation is a technique that can be used to obtain probability distribution from experts about unknown quantities. We conducted a methodology review of reports where probability distributions had been elicited from experts to be used in model-based health technology assessments. Databases including MEDLINE, EMBASE and the CRD database were searched from inception to April 2013. Reference lists were checked and citation mapping was also used. Studies describing their approach to the elicitation of probability distributions were included. Data was abstracted on pre-defined aspects of the elicitation technique. Reports were critically appraised on their consideration of the validity, reliability and feasibility of the elicitation exercise. Fourteen articles were included. Across these studies, the most marked features were heterogeneity in elicitation approach and failure to report key aspects of the elicitation method. The most frequently used approaches to elicitation were the histogram technique and the bisection method. Only three papers explicitly considered the validity, reliability and feasibility of the elicitation exercises. Judged by the studies identified in the review, reports of expert elicitation are insufficient in detail and this impacts on the perceived usability of expert-elicited probability distributions. In this context, the wider credibility of elicitation will only be improved by better reporting and greater standardisation of approach. Until then, the advantage of eliciting probability distributions from experts may be lost.

Systematic review of reusable versus disposable laparoscopic instruments: costs and safety.

Siu, Joey; Hill, Andrew G; MacCormick, Andrew D

2017-01-01

The quality of instruments and surgical expertise in minimally invasive surgery has developed markedly in the last two decades. Attention is now being turned to ways to allow surgeons to adopt more cost-effective and environmental-friendly approaches. This review explores current evidence on the cost and environmental impact of reusable versus single-use instruments. In addition, we aim to compare their quality, functionality and associated clinical outcomes. The Medline and EMBASE databases were searched for relevant literature from January 2000 to May 2015. Subject headings were Equipment Reuse/, Disposable Equipment/, Cholecystectomy/, Laparoscopic/, Laparoscopy/, Surgical Instruments/, Medical Waste Disposal/, Waste Management/, Medical Waste/, Environmental Sustainability/ and Sterilization/. There are few objective comparative analyses between single-use versus reusable instruments. Current evidence suggests that limiting use of disposal instruments to necessity may hold both economical and environmental advantages. Theoretical advantages of single-use instruments in quality, safety, sterility, ease of use and importantly patient outcomes have rarely been examined. Cost-saving methods, environmental-friendly methods, global operative costs, hidden costs, sterilization methods and quality assurance systems vary greatly between studies making it difficult to gain an overview of the comparison between single-use and reusable instruments. Further examination of cost comparisons between disposable and reusable instruments is necessary while externalized environmental costs, instrument function and safety are also important to consider in future studies. © 2016 Royal Australasian College of Surgeons.

The search was performed in the following databases: Medline, Cinahl, Embase, Lilacs, Scielo, Web of Science, PEDro, Cochrane Controlled Trials Register Library, Scopus, Science Direct and Google Scholar. (1950-2014). Included studies were randomized controlled trials (RCTs) that assessed the effects of the Pilates method on healthy subjects. Nine RCTs met the inclusion criteria. Pilates improved abdominal muscular endurance when compared with no exercises (mean difference [MD]=9.53%; 95% CI: 2.41, 16.43; P=0.009), however, there was no difference in flexibility (MD=4.97; 95% CI: -0.53, 10.47; P=0.08). Some positive effects (up to 6 months) of the Pilates practice were found in some RCTs' results as follows: Improvement of dynamic balance, quality of life and back muscle flexibility. The results indicate the Pilates exercises performed on the mat or apparatus 2 to 3 times a week, for 5 to 12 weeks, improves abdominal muscular endurance (on average, 10 more abdominals curls in 1-minute sit-up test) for both genders, when compared to no exercises.

Association of HLA-B*5801 allele and allopurinol-induced stevens johnson syndrome and toxic epidermal necrolysis: a systematic review and meta-analysis

Background Despite some studies suggesting a possible association between human leukocyte antigen, HLA-B*5801 and allopurinol induced Stevens-Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN), the evidence of association and its magnitude remain inconclusive. This study aims to systematically review and meta-analyze the association between HLA-B*5801 allele and allopurinol-induced SJS/TEN. Methods A comprehensive search was performed in databases including MEDLINE, Pre-MEDLINE, Cochrane Library, EMBASE, International Pharmaceutical Abstracts (IPA), CINAHL, PsychInfo, the WHO International, Clinical Trial Registry, and ClinicalTrial.gov from their inceptions to June 2011. Only studies investigating association between HLA-B*5801 with allopurinol-induced SJS/TEN were included. All studies were extracted by two independent authors. The primary analysis was the carrier frequency of HLA-B*5801 comparison between allopurinol-induced SJS/TEN cases and each comparative group. The pooled odds ratios were calculated using a random effect model. Results A total of 4 studies with 55 SJS/TEN cases and 678 matched-controls (allopurinol-tolerant control) was identified, while 5 studies with 69 SJS/TEN cases and 3378 population-controls (general population) were found. SJS/TEN cases were found to be significantly associated with HLA-B*5801 allele in both groups of studies with matched-control (OR 96.60, 95%CI 24.49-381.00, p < 0.001) and population-control (OR 79.28, 95%CI 41.51-151.35, p < 0.001). Subgroup analysis for Asian and Non-Asian population yielded similar findings. Conclusion We found a strong and significant association between HLA-B*5801 and allopurinol-induced SJS/TEN. Therefore, HLA-B*5801 allele screening may be considered in patients who will be treated with allopurinol. PMID:21906289

Pediatrics has embraced technology-enhanced simulation (TES) as an educational modality, but its effectiveness for pediatric education remains unclear. The objective of this study was to describe the characteristics and evaluate the effectiveness of TES for pediatric education. This review adhered to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) standards. A systematic search of Medline, Embase, CINAHL, ERIC, Web of Science, Scopus, key journals, and previous review bibliographies through May 2011 and an updated Medline search through October 2013 were conducted. Original research articles in any language evaluating the use of TES for educating health care providers at any stage, where the content solely focuses on patients 18 years or younger, were selected. Reviewers working in duplicate abstracted information on learners, clinical topic, instructional design, study quality, and outcomes. We coded skills (simulated setting) separately for time and nontime measures and similarly classified patient care behaviors and patient effects. We identified 57 studies (3666 learners) using TES to teach pediatrics. Effect sizes (ESs) were pooled by using a random-effects model. Among studies comparing TES with no intervention, pooled ESs were large for outcomes of knowledge, nontime skills (eg, performance in simulated setting), behaviors with patients, and time to task completion (ES = 0.80-1.91). Studies comparing the use of high versus low physical realism simulators showed small to moderate effects favoring high physical realism (ES = 0.31-0.70). TES for pediatric education is associated with large ESs in comparison with no intervention. Future research should include comparative studies that identify optimal instructional methods and incorporate pediatric-specific issues into educational interventions.

OBJECTIVE Diets with high glycemic index (GI), with high glycemic load (GL), or high in all carbohydrates may predispose to higher blood glucose and insulin concentrations, glucose intolerance, and risk of type 2 diabetes. We aimed to conduct a systematic literature review and dose–response meta-analysis of evidence from prospective cohorts. RESEARCH DESIGN AND METHODS We searched the Cochrane Library, MEDLINE, MEDLINE in-process, Embase, CAB Abstracts, ISI Web of Science, and BIOSIS for prospective studies of GI, GL, and total carbohydrates in relation to risk of type 2 diabetes up to 17 July 2012. Data were extracted from 24 publications on 21 cohort studies. Studies using different exposure categories were combined on the same scale using linear and nonlinear dose–response trends. Summary relative risks (RRs) were estimated using random-effects meta-analysis. RESULTS The summary RR was 1.08 per 5 GI units (95% CI 1.02–1.15; P = 0.01), 1.03 per 20 GL units (95% CI 1.00–1.05; P = 0.02), and 0.97 per 50 g/day of carbohydrate (95% CI 0.90–1.06; P = 0.5). Dose–response trends were linear for GI and GL but more complex for total carbohydrate intake. Heterogeneity was high for all exposures (I2 >50%), partly accounted for by different covariate adjustment and length of follow-up. CONCLUSIONS Included studies were observational and should be interpreted cautiously. However, our findings are consistent with protective effects of low dietary GI and GL, quantifying the range of intakes associated with lower risk. Future research could focus on the type of sugars and other carbohydrates associated with greatest risk. PMID:24265366

Background Lung cancer is the leading cause of cancer deaths. Around 70% of patients first presenting to specialist care have advanced disease, at which point current treatments have little effect on survival. The issue for primary care is how to recognise patients earlier and investigate appropriately. This requires an assessment of the risk of lung cancer. Aim The aim of this study was to systematically review the existing risk prediction tools for patients presenting in primary care with symptoms that may indicate lung cancer Design and setting Systematic review of primary care data. Method Medline, PreMedline, Embase, the Cochrane Library, Web of Science, and ISI Proceedings (1980 to March 2016) were searched. The final list of included studies was agreed between two of the authors, who also appraised and summarised them. Results Seven studies with between 1482 and 2 406 127 patients were included. The tools were all based on UK primary care data, but differed in complexity of development, number/type of variables examined/included, and outcome time frame. There were four multivariable tools with internal validation area under the curves between 0.88 and 0.92. The tools all had a number of limitations, and none have been externally validated, or had their clinical and cost impact examined. Conclusion There is insufficient evidence for the recommendation of any one of the available risk prediction tools. However, some multivariable tools showed promising discrimination. What is needed to guide clinical practice is both external validation of the existing tools and a comparative study, so that the best tools can be incorporated into clinical decision tools used in primary care.

To determine pooled prevalence of clinically significant traits or features of Borderline Personality Disorder among college students, and explore the influence of methodological factors on reported prevalence figures, and temporal trends. Electronic databases (1994-2014: AMED; Biological Abstracts; Embase; MEDLINE; PsycARTICLES; CINAHL Plus; Current Contents Connect; EBM Reviews; Google Scholar; Ovid Medline; Proquest central; PsychINFO; PubMed; Scopus; Taylor & Francis; Web of Science (1998-2014), and hand searches. Forty-three college-based studies reporting estimates of clinically significant BPD symptoms were identified (5.7% of original search). One author (RM) extracted clinically relevant BPD prevalence estimates, year of publication, demographic variables, and method from each publication or through correspondence with the authors. The prevalence of BPD in college samples ranged from 0.5% to 32.1%, with lifetime prevalence of 9.7% (95% CI, 7.7-12.0; p < .005). Methodological factors contributing considerable between-study heterogeneity in univariate meta-analyses were participant anonymity, incentive type, research focus and participant type. Study and sample characteristics related to between study heterogeneity were sample size, and self-identifying as Asian or "other" race. The prevalence of BPD varied over time: 7.8% (95% CI 4.2-13.9) between 1994 and 2000; 6.5% (95% CI 4.0-10.5) during 2001 to 2007; and 11.6% (95% CI 8.8-15.1) from 2008 to 2014, yet was not a source of heterogeneity (p = .09). BPD prevalence estimates are influenced by the methodological or study sample factors measured. There is a need for consistency in measurement across studies to increase reliability in establishing the scope and characteristics of those with BPD engaged in tertiary study.

Similarities and differences across borders of Nordic countries constitute a suitable context for investigating and discussing factors related to the development of diabetes nursing research over the last three decades. The present study reviewed the entire body of contemporary diabetes nursing research literature originating in four Nordic countries: Norway, Sweden, Denmark and Iceland. Our aims were (i) to catalogue and characterise trends in research designs and research areas of these studies published over time and (ii) to describe how research involving nurses in Nordic countries has contributed to diabetes research overall. The larger goal of our analyses was to produce a comprehensive picture of this research in order to guide future studies in the field. We conducted a narrative literature review by systematically searching Medline, Medline in process, EMBASE, CINAHL, PsycINFO and Cochrane databases. These searches were limited to studies published between 1979 and 2009 that had an abstract available in English or a Nordic language. Two researchers independently selected studies for analysis, leading to the inclusion of 164 relevant publications for analysis. In summary, Nordic nurse researchers have contributed to the development of new knowledge in self-management of diabetes in childhood, adolescence and adulthood, and to some extent also in the treatment and care of diabetes foot ulcers. Future research may benefit from (i) larger nurse-led research programmes organised in networks in order to share knowledge and expertise across national groups and borders, (ii) more multidisciplinary collaborations in order to promote patient-centred care and (iii) further research directed towards improving the dissemination and implementation of research findings. Using complex intervention designs and a mix of research methods will enrich the research. © 2015 Nordic College of Caring Science.

To describe the basis on which our knowledge of frequent attendance in general practice rests and to propose recommendations for further research on frequent attenders (FAs). The literature review (finished February 2004) encompassed peer-reviewed articles in English describing contacts with general practice in terms of frequency. Searches were performed in the Medline, CINAHL, EMBASE, PsycINFO, Social Sciences Expanded Index and ISI Citation databases with additional searches in reference lists and the 'related articles' function in the ISI Citation database and Medline. General practice. Sixty-one articles (54 studies). The articles were assessed according to the following design variables: setting; definition of FAs; sampling; sample size; control groups; study aim; study design; data sources; effect measure; and main results. There was no generally accepted definition of frequent attendance. Research designs differed substantially. Eight articles gave sufficient information on all design variables. The top 10% of attenders accounted for 30-50% of all contacts, and up to 40% of FAs were still FAs the following year. More than 50% of FAs had a physical disease, more than 50% of FAs suffered from psychological distress, social factors (low social support, unemployment, divorce) were associated with frequent attendance in more than 50% of FAs, multiproblems (physical, psychological and social) were found in one-third of FAs, and frequent attendance was associated with increasing age and female gender. The diversity of designs, definitions and methods in the current literature on FAs in general practice hampers comparison of their precision, validity and generalizability, and calls for cautious interpretation and adoption of a common, generally acceptable definition in future studies.

INTRODUCTION: The present study was motivated by the need to systematically assess the research productivity of the Heart Institute (InCor), Medical School of the University of São Paulo, Brazil. OBJECTIVE: To explore methodology for the assessment of institutional scientific research productivity. MATERIALS AND METHODS: Bibliometric indicators based on searches for author affiliation of original scientific articles or reviews published in journals indexed in the databases Web of Science, MEDLINE, EMBASE, LILACS and SciELO from January 2000 to December 2003 were used in this study. The retrieved records were analyzed according to the index parameters of the journals and modes of access. The number of citations was used to calculate the institutional impact factor. RESULTS: Out of 1253 records retrieved from the five databases, 604 original articles and reviews were analyzed; of these, 246 (41%) articles were published in national journals and 221 (90%) of those were in journals with free online access through SciELO or their own websites. Of the 358 articles published in international journals, 333 (93%) had controlled online access and 223 (67%) were available through the Capes Portal of Journals. The average impact of each article for InCor was 2.224 in the period studied. CONCLUSION: A simple and practical methodology to evaluate the scientific production of health research institutions includes searches in the LILACS database for national journals and in MEDLINE and the Web of Science for international journals. The institutional impact factor of articles indexed in the Web of Science may serve as a measure by which to assess and review the scientific productivity of a research institution. PMID:19578662

Health Technology Assessment (HTA) agencies often undertake a review of economic evaluations of an intervention during an appraisal in order to identify published estimates of cost-effectiveness, to elicit comparisons with the results of their own model, and to support local reimbursement decision-making. The aim of this research is to determine whether Transcatheter Aortic Valve Implantation (TAVI) compared to medical management (MM) is cost-effective in patients ineligible for surgical aortic valve replacement (SAVR), across different jurisdictions and country-specific evaluations. A systematic review of the literature from 2007-2012 was performed in the MEDLINE, MEDLINE in-process, EMBASE, and UK NHS EED databases according to standard methods, supplemented by a search of published HTA models. All identified publications were reviewed independently by two health economists. The British Medical Journal (BMJ) 35-point checklist for economic evaluations was used to assess study reporting. To compare results, incremental cost effectiveness ratios (ICERs) were converted to 2012 dollars using purchasing power parity (PPP) techniques. Six studies were identified representing five reimbursement jurisdictions (England/Wales, Scotland, the US, Canada, and Belgium) and different modeling techniques. The identified economic evaluations represent different willingness-to-pay thresholds, discount rates, medical costs, and healthcare systems. In addition, the model structures, time horizons, and cycle lengths varied. When adjusting for differences in currencies, the ICERs ranged from $27K-$65K per QALY gained. Despite notable differences in modeling approach, under the thresholds defined by using either the local threshold value or that recommended by the World Health Organization (WHO) threshold value, each study showed that TAVI was likely to be a cost-effective intervention for patients ineligible for SAVR.

Objective The objective of this study was to examine the religious/spiritual beliefs of followers of the five major world religions about frequently encountered medical situations at the end of life (EoL). Method This was a systematic review of observational studies on the religious aspects of commonly encountered EoL situations. The databases used for retrieving studies were: Ovid MEDLINE In-Process & Other Non-Indexed Citations, Ovid MEDLINE, Ovid EMBASE, Ovid PsycINFO, Ovid Cochrane Central Register of Controlled Trials, Ovid Cochrane Database of Systematic Reviews, and Scopus. Observational studies, including surveys from healthcare providers or the general population, and case studies were included for review. Articles written from a purely theoretical or philosophical perspective were excluded. Results Our search strategy generated 968 references, 40 of which were included for review, while 5 studies were added from reference lists. Whenever possible, we organized the results into five categories that would be clinically meaningful for palliative care practices at the EoL: advanced directives, euthanasia and physician-assisted suicide, physical requirements (artificial nutrition, hydration, and pain management), autopsy practices, and other EoL religious considerations. A wide degree of heterogeneity was observed within religions, depending on the country of origin, level of education, and degree of intrinsic religiosity. Significance of results Our review describes the religious practices pertaining to major EoL issues and explains the variations in EoL decision making by clinicians and patients based on their religious teachings and beliefs. Prospective studies with validated tools for religiosity should be performed in the future to assess the impact of religion on EoL care. PMID:28901283

Memory loss is the most prominent symptoms of brain aging, but there is currently no evidence-based treatment strategy. Acupuncture has been widely used in China and the effectiveness for improving learning and memory has been mentioned in previous studies. We conducted this systematic review and meta-analysis to evaluate the effectiveness of acupuncture for improving learning and memory in animal experiments. We searched Pubmed, Embase, Ovid Medline(R), the China National Knowledge Infrastructure (CNKI), Chinese Science and Technology Periodical Database (VIP) and Wanfang data Information Site to collect studies published up to December 2015. Study quality for each included article was evaluated according to the CAMARADES 10-item checklist. Outcome measure is Morris water maze. A meta-analysis was conducted according to the Cochrane systematic review method by using RevMan 5.3 software. Forty-two studies involving 944 animals were included. The quality score of the studies ranged from 2 to 8, with a mean of 5.3. Meta-analysis results showed that 24 studies reported significant effect of acupuncture for decreasing escape latency (-3.00, 95 % CI: -3.78 ~ -2.23, P < 0.00001), 14 studies reported significant effect of acupuncture for increasing frequency of cross platform (2.57, 95 % CI: 1.92 ~ 3.22, P < 0.00001), and 7 studies reported significant effect of acupuncture for increasing time in target quadrant (2.00, 95 % CI: 1.10 ~ 2.91, P < 0.00001) compared with the control group. These findings show acupuncture has a potential role in improving learning and memory ability in animal models, suggesting it as a candidate therapy for memory loss of aged brain.

Electronic whiteboards are being introduced into hospitals to communicate real-time patient information instantly to staff. This paper provides a preliminary review of the current state of evidence for the effect of electronic whiteboards on care processes and patient outcomes. A literature search was performed for the dates 1996 to 2014 on MEDLINE, EMBASE, IEEE Xplore, Science Direct, and the ACM Digital Library. Thirteen papers, describing 11 studies, meeting the inclusion criteria were identified. The majority of studies took place in the Emergency Department. While studies looked at the impact of electronic whiteboards on the process of care, there is an absence of evidence concerning impact on patient outcomes. There is a need for robust research measuring the impact of electronic whiteboards on inpatient care.

Although epidemiologic evidence has not supported the hypothesis of a causal relationship between thimerosal-containing vaccines and autism, concerns continue about pediatric exposure to mercury through vaccine administration. A statement issued by the American Academy of Pediatrics and the US Public Health Service in 1999 prompted the removal of thimerosal from many vaccines. In 2004, the Immunization Safety Review Committee of the Institute of Medicine rejected the hypothesis of a causal relationship between thimerosal-containing vaccines and autism.In a search of MEDLINE and EMBASE, we identified articles that address the potential association between thimerosal and neurodevelopmental disorders, specifically autism. In this article, we review recent pharmacokinetic and epidemiologic studies published between 2003 and 2008 regarding the proposed link between thimerosal and autism.

Intraoperative radiotherapy (IORT) is a highly specialized component of multidisciplinary management of advanced and recurrent colorectal cancer. The aim of this review was to assess its role and effectiveness in the management of colorectal cancer. A literature search was performed using Medline, Embase, Ovid and Cochrane to identify English language studies which have used IORT in the multidisciplinary management of primary and recurrent colon and rectal cancers. Improved survival and local control in patients with involved surgical margins treated with IORT have been shown in many studies, but these results have been mainly from retrospective studies. There is associated morbidity from IORT. IORT does have a role in the management of colorectal cancer. Further research needs to be performed to optimize the application of this therapy.

To determine whether problem based learning (PBL) is an effective educational strategy in chronic disease management. The databases CINAHL, EMBASE, HealthStar, Medline and PubMed were searched for articles which focused on PBL and patient education or patient learning. Individual studies using PBL as an intervention with chronic disease management reflect significant changes in cognitive and clinical outcomes among individuals experiencing diabetes, asthma, arthritis and coronary artery disease. There is a need for more well designed studies that assess the impact of PBL on self-care management of a variety of chronic diseases. There is some evidence that PBL is effective in promoting self-care with individuals experiencing diabetes, arthritis, asthma and coronary artery disease. 2009 Published by Elsevier Ireland Ltd.

This fifth best practice review examines three series of common primary care questions in laboratory medicine: (1) minor liver function test abnormalities; (2) laboratory monitoring of patients receiving lithium; and (3) investigation of possible venous thromboembolism. The review is presented in question–answer format, referenced for each question series. The recommendations represent a precis of guidance found using a standardised literature search of national and international guidance notes, consensus statements, health policy documents and evidence‐based medicine reviews, supplemented by Medline Embase searches to identify relevant primary research documents. They are not standards but form a guide to be set in the clinical context. Most are consensus‐based rather than evidence‐based. They will be updated periodically to take account of new information.

Stress incontinence and pelvic floor exercises in pregnancy.

PubMed

Sahakian, Josine

This literature review is a critique of the research looking at the impact of pelvic floor exercises during pregnancy on urinary stress incontinence in postnatal women. Seven studies were selected for review following a database search on the Cumulative Index to Nursing and Allied Health Literature (CINAHL), Embase, Medline and the British Nursing Index (BNI). The research produced mixed findings. Four of the seven studies demonstrated a significant improvement in urinary stress incontinence in postnatal women following pelvic floor muscle exercise during pregnancy. However, the studies that spanned a longer time period found no long-term effectiveness. More research is needed for a more conclusive picture as to whether antenatal pelvic floor exercises can improve stress incontinence in the postpartum period.

Symptom Cluster Research With Biomarkers and Genetics Using Latent Class Analysis.

PubMed

Conley, Samantha

2017-12-01

The purpose of this article is to provide an overview of latent class analysis (LCA) and examples from symptom cluster research that includes biomarkers and genetics. A review of LCA with genetics and biomarkers was conducted using Medline, Embase, PubMed, and Google Scholar. LCA is a robust latent variable model used to cluster categorical data and allows for the determination of empirically determined symptom clusters. Researchers should consider using LCA to link empirically determined symptom clusters to biomarkers and genetics to better understand the underlying etiology of symptom clusters. The full potential of LCA in symptom cluster research has not yet been realized because it has been used in limited populations, and researchers have explored limited biologic pathways.

Although cannabis use is associated with an increased risk of developing psychosis, the cannabis constituent cannabidiol (CBD) may have antipsychotic properties. This review concisely describes the role of the endocannabinoid system in the development of psychosis and provides an overview of currently available animal, human experimental, imaging, epidemiological and clinical studies that investigated the antipsychotic properties of CBD. In this targeted literature review we performed a search for English articles using Medline and EMBASE. Studies were selected if they described experiments with psychosis models, psychotic symptoms or psychotic disorders as outcome measure and involved the use of CBD as intervention. Evidence from several research domains suggests that CBD shows potential for antipsychotic treatment. © 2013 Published by Elsevier B.V. and ECNP.

Robotic surgery is becoming more and more commonplace. At the same time, so are complications, especially related to erectile function. The population being diagnosed with cancer is younger, with more aggressive cancers and higher expectations for good erectile function postoperatively. We conduct a retrospective analysis of literature over 20 years for Embase and Medline. Search terms used include (Robotic) AND (prostatectomy) AND (erectile function). There are a variety of multifactorial causes, resulting in worsening ED post-robotic radical prostatectomy; however, there are a number of treatments that can support this. There is much we can do to help prevent patients getting postoperative erectile dysfunction post-radical surgery. However, part of this is management of realistic patient expectations.

Background Randomised controlled trials (RCTs) are widely accepted as the preferred study design for evaluating healthcare interventions. When the sample size is determined, a (target) difference is typically specified that the RCT is designed to detect. This provides reassurance that the study will be informative, i.e., should such a difference exist, it is likely to be detected with the required statistical precision. The aim of this review was to identify potential methods for specifying the target difference in an RCT sample size calculation. Methods and Findings A comprehensive systematic review of medical and non-medical literature was carried out for methods that could be used to specify the target difference for an RCT sample size calculation. The databases searched were MEDLINE, MEDLINE In-Process, EMBASE, the Cochrane Central Register of Controlled Trials, the Cochrane Methodology Register, PsycINFO, Science Citation Index, EconLit, the Education Resources Information Center (ERIC), and Scopus (for in-press publications); the search period was from 1966 or the earliest date covered, to between November 2010 and January 2011. Additionally, textbooks addressing the methodology of clinical trials and International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) tripartite guidelines for clinical trials were also consulted. A narrative synthesis of methods was produced. Studies that described a method that could be used for specifying an important and/or realistic difference were included. The search identified 11,485 potentially relevant articles from the databases searched. Of these, 1,434 were selected for full-text assessment, and a further nine were identified from other sources. Fifteen clinical trial textbooks and the ICH tripartite guidelines were also reviewed. In total, 777 studies were included, and within them, seven methods were identified—anchor, distribution, health economic, opinion-seeking, pilot study, review of the evidence base, and standardised effect size. Conclusions A variety of methods are available that researchers can use for specifying the target difference in an RCT sample size calculation. Appropriate methods may vary depending on the aim (e.g., specifying an important difference versus a realistic difference), context (e.g., research question and availability of data), and underlying framework adopted (e.g., Bayesian versus conventional statistical approach). Guidance on the use of each method is given. No single method provides a perfect solution for all contexts. Please see later in the article for the Editors' Summary PMID:24824338

2014-01-01

Background Dipyrone (metamizole) is a non-steroidal anti-inflammatory drug used in some countries to treat pain (postoperative, colic, cancer, and migraine); it is banned in others because of an association with life-threatening blood agranulocytosis. This review updates a 2001 Cochrane review, and no relevant new studies were identified, but additional outcomes were sought. Objectives To assess the efficacy and adverse events of single dose dipyrone in acute postoperative pain. Search methods The earlier review searched CENTRAL, MEDLINE, EMBASE, LILACS and the Oxford Pain Relief Database to December 1999. For the update we searched CENTRAL, MEDLINE,EMBASE and LILACS to February 2010. Selection criteria Single dose, randomised, double-blind, placebo or active controlled trials of dipyrone for relief of established moderate to severe postoperative pain in adults. We included oral, rectal, intramuscular or intravenous administration of study drugs. Data collection and analysis Studies were assessed for methodological quality and data extracted by two review authors independently. Summed total pain relief over six hours (TOTPAR) was used to calculate the number of participants achieving at least 50% pain relief. Derived results were used to calculate, with 95% confidence intervals, relative benefit compared to placebo, and the number needed to treat (NNT) for one participant to experience at least 50% pain relief over six hours. Use and time to use of rescue medication were additional measures of efficacy. Information on adverse events and withdrawals was collected. Main results Fifteen studies tested mainly 500 mg oral dipyrone (173 participants), 2.5 g intravenous dipyrone (101), 2.5 g intramuscular dipyrone (99); fewer than 60 participants received any other dose. All studies used active controls (ibuprofen, paracetamol, aspirin, flurbiprofen, ketoprofen, dexketoprofen, ketorolac, pethidine, tramadol, suprofen); eight used placebo controls. Over 70% of participants experienced at least 50% pain relief over 4 to 6 hours with oral dipyrone 500 mg compared to 30% with placebo in five studies (288 participants; NNT 2.4 (1.9 to 3.2)). Fewer participants needed rescue medication with dipyrone (7%) than with placebo (34%; four studies, 248 participants). There was no difference in participants experiencing at least 50% pain relief with 2.5 g intravenous dipyrone and 100 mg intravenous tramadol (70% vs 65%; two studies, 200 participants). No serious adverse events were reported. Authors’ conclusions Based on very limited information, single dose dipyrone 500 mg provides good pain relief to 70% of patients. For every five individuals given dipyrone 500 mg, two would experience this level of pain relief who would not have done with placebo, and fewer would need rescue medication, over 4 to 6 hours.

To report methods of measurement of radiographic displacement and radiographic outcomes in acetabular fractures described in the literature. A systematic review of the English literature was performed using EMBASE and Medline in August 2014. Inclusion criteria were studies of operatively treated acetabular fractures in adults with acute (<6 weeks) open reduction and internal fixation that reported radiographic outcomes. Exclusion criteria included case series with <10 patients, fractures managed >6 weeks from injury, acute total hip arthroplasty, periprosthetic fractures, time frame of radiographic outcomes not stated, missing radiographic outcome data, and non-English language articles. Basic information collected included journal, author, year published, number of fractures, and fracture types. Specific data collected included radiographic outcome data, method of measuring radiographic displacement, and methods of interpreting or categorizing radiographic outcomes. The number of reproducible radiographic measurement techniques (2/64) and previously described radiographic interpretation methods (4) were recorded. One radiographic reduction grading criterion (Matta) was used nearly universally in articles that used previously described criteria. Overall, 70% of articles using this criteria documented anatomic reductions. The current standard of measuring radiographic displacement in publications dealing with acetabulum fractures almost universally lacks basic description, making further scientific rigor, such as testing reproducibility, impossible. Further work is necessary to standardize radiographic measurement techniques, test their reproducibility, and qualify their validity or determine which measurements are important to clinical outcomes.

NBOMe is a class of emerging new psychoactive substances that has recently gained prominence in the drug abuse market. NBOMes are N-2-methoxy-benzyl substituted 2C class of hallucinogens, currently being marked online as "research chemicals" under various names: N-bomb, Smiles, Solaris, and Cimbi. This article reviews available literature on the pharmacology; the analytical methods currently used for the detection and quantification of NBOMe in biological matrices and blotters, together with intoxication cases and NBOMe-related fatalities. Relevant scientific articles were identified from Medline, Cochrane Central, Scopus, Web of Science, Science Direct, EMBASE and Google Scholar, through June 2015 using the following keywords: "NBOMe", "Nbomb", "Smiles", "intoxication", "toxicity" "fatalities", "death", "pharmacology", "5-HT2A receptor", "analysis" and "analytical methods". The main key word "NBOMe" was individually searched in association to each of the others. The review of the literature allowed us to identify 43 citations on pharmacology, analytical methods and NBOMe-related toxicities and fatalities. The high potency of NBOMes (potent agonists of 5-HT2A receptor) has led to several severe intoxications, overdose and traumatic fatalities; thus, their increase raises significant public health concerns. Moreover, due to the high potency and ease of synthesis, it is likely that their recreational use will become more widespread in the future. The publication of new data, case reports and evaluation of the NBOMes metabolites is necessary in order to improve knowledge and awareness within the forensic community.

To establish the effectiveness of walking alone and walking compared to other non-pharmacological management methods to improve disability, quality of life, or function in adults with chronic low back pain. A systematic search of the following databases was undertaken: Medline, Embase, CINAHL, Scopus, Pedro, SportDiscus, Cochrane Central Register of Controlled Trials. The following keywords were used: 'back pain' or 'low back pain' or 'chronic low back pain' and 'walk*' or 'ambulation' or 'treadmill*' or 'pedometer*' or 'acceleromet*' or 'recreational' and 'disability' or 'quality of life' or 'function*'. Primary research studies with an intervention focus that investigated walking as the primary intervention compared to no intervention or any other non-pharmacological method in adults with chronic low back pain (duration >3 months). Seven randomised controlled trials involving 869 participants were included in the review. There was no evidence that walking was more effective than other management methods such as usual care, specific strength exercises, medical exercise therapy, or supervised exercise classes. One study found over-ground walking to be superior to treadmill walking, and another found internet-mediated walking to be more beneficial than non-internet-mediated walking in the short term. There is low quality evidence to suggest that walking is as effective as other non-pharmacological management methods at improving disability, function, and quality of life in adults with chronic low back pain. © The Author(s) 2015.

Enhancing transparency in reporting the synthesis of qualitative research: ENTREQ

PubMed Central

2012-01-01

Background The syntheses of multiple qualitative studies can pull together data across different contexts, generate new theoretical or conceptual models, identify research gaps, and provide evidence for the development, implementation and evaluation of health interventions. This study aims to develop a framework for reporting the synthesis of qualitative health research. Methods We conducted a comprehensive search for guidance and reviews relevant to the synthesis of qualitative research, methodology papers, and published syntheses of qualitative health research in MEDLINE, Embase, CINAHL and relevant organisational websites to May 2011. Initial items were generated inductively from guides to synthesizing qualitative health research. The preliminary checklist was piloted against forty published syntheses of qualitative research, purposively selected to capture a range of year of publication, methods and methodologies, and health topics. We removed items that were duplicated, impractical to assess, and rephrased items for clarity. Results The Enhancing transparency in reporting the synthesis of qualitative research (ENTREQ) statement consists of 21 items grouped into five main domains: introduction, methods and methodology, literature search and selection, appraisal, and synthesis of findings. Conclusions The ENTREQ statement can help researchers to report the stages most commonly associated with the synthesis of qualitative health research: searching and selecting qualitative research, quality appraisal, and methods for synthesising qualitative findings. The synthesis of qualitative research is an expanding and evolving methodological area and we would value feedback from all stakeholders for the continued development and extension of the ENTREQ statement.

What Do We Know about Knowledge Brokers in Paediatric Rehabilitation? A Systematic Search and Narrative Summary

PubMed Central

Verrier, Molly C.; Landry, Michel D.

2014-01-01

ABSTRACT Purpose: To conduct a systematic review of the literature related to the use of knowledge brokers within paediatric rehabilitation, and specifically to determine (1) how knowledge brokers are defined and used in paediatric rehabilitation and (2) whether knowledge brokers in paediatric rehabilitation have demonstrably improved the performance of health care providers or organizations. Methods: The MEDLINE, CINAHL, EMBASE, and AMED databases were systematically searched to identify studies relating to knowledge brokers or knowledge brokering within paediatric rehabilitation, with no restriction on the study design or primary aim. Following review of titles and abstracts, those studies identified as potentially relevant were assessed based on the inclusion criteria that they: (1) examined some aspect of knowledge brokers/brokering in paediatric rehabilitation; (2) included sufficient descriptive detail on how knowledge brokers/brokering were used; and(3) were peer-reviewed and published in English. Results: Of 1513 articles retrieved, 4 met the inclusion criteria, 3 of which referenced the same knowledge broker initiative. Two papers used mixed methods, one qualitative methodology, and one case presentation. Because of the different methods used in the included studies, the findings are presented in a narrative summary. Conclusions: This study provides an overview of the limited understanding of knowledge brokers within paediatric rehabilitation. Knowledge broker initiatives introduced within paediatric rehabilitation have been anchored in different theoretical frameworks, and no conclusions can be drawn as to the optimum combination of knowledge brokering activities and methods, nor about optimal duration, for sustained results.

Ketamine as an adjuvant to opioids for cancer pain.

PubMed

Bell, Rae F; Eccleston, Christopher; Kalso, Eija A

2012-11-14

This is an update of the original review published in Issue 1, 2003. Ketamine is a commonly used anaesthetic agent, and in subanaesthetic doses is also given as an adjuvant to opioids for the treatment of cancer pain, particularly when opioids alone prove to be ineffective. Ketamine is known to have psychotomimetic (including hallucinogenic), urological and hepatic adverse effects. To determine the effectiveness and adverse effects of ketamine as an adjuvant to opioids in the treatment of cancer pain. Studies were originally identified from MEDLINE (1966 to 2002), EMBASE (1980 to 2002), CancerLit (1966 to 2002), The Cochrane Library (Issue 1, 2001); by handsearching reference lists from review articles, trials, and chapters from standard textbooks on pain and palliative care. The manufacturer of ketamine (Pfizer Parke-Davis) provided search results from their in-house database, PARDLARS.An improved and updated search of the following was performed in May 2012: CENTRAL, MEDLINE & OVID MEDLINE R, EMBASE. Randomized controlled trials (RCTs) of adult patients with cancer and pain being treated with an opioid, and receiving either ketamine (any dose and any route of administration) or placebo or an active control. Studies having a group size of at least 10 participants who completed the trial. Two independent review authors identified four RCTs for possible inclusion in the review, and 32 case studies/case series reports. Quality and validity assessment was performed by three independent review authors, and two RCTs were excluded because of inappropriate study design. Patient-reported pain intensity and pain relief was assessed using visual analogue scales (VAS), verbal rating scales or other validated scales, and adverse effects data were collated. For the update three RCTs were identified for possible inclusion in the review. Three new studies were identified by the updated search. All three were excluded from the review. Two studies were eligible for inclusion in the original review and both concluded that ketamine improves the effectiveness of morphine in the treatment of cancer pain. However, pooling of the data was not appropriate because of the small total number of participants (30), and the presence of clinical heterogeneity. Some patients experienced hallucinations on both ketamine plus morphine and morphine alone and were treated successfully with diazepam. No other serious adverse effects were reported. Since the last version of this review three new studies were identified but excluded from the review. Current evidence is insufficient to assess the benefits and harms of ketamine as an adjuvant to opioids for the relief of cancer pain. More RCTs are needed.

2015-09-24

This is an updated version of the original Cochrane review published in Issue 3 (Lee 2012) on patient positioning (mobilisation) and bracing for pain relief and spinal stability in adults with metastatic spinal cord compression.Many patients with metastatic spinal cord compression (MSCC) have spinal instability, but their clinician has determined that due to their advanced disease they are unsuitable for surgical internal fixation. Mobilising may be hazardous in the presence of spinal instability as further vertebral collapse can occur. Current guidance on positioning (whether a patient should be managed with bed rest or allowed to mobilise) and whether spinal bracing is helpful, is contradictory. To investigate the correct positioning and examine the effects of spinal bracing to relieve pain or to prevent further vertebral collapse in patients with MSCC. For this update, we searched for relevant studies from February 2012 to 31 March 2015. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and MEDLINE In Process, EMBASE, AMED, CINAHL, TRIP, SIGN, NICE, UK Clinical Research Network, National Guideline Clearinghouse and PEDro database. We also searched the metaRegister of Controlled Trials (mRCT), ClinicalTrials.gov, UK Clinical Trials Gateway (UKCTG), WHO International Clinical Trials Registry Platform (ICTRP) and Australia New Zealand Clinical Trials Registry (ANZCTR).For the original version, we searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL, CANCERLIT, NICE, SIGN, AMED, TRIP, National Guideline Clearinghouse, and PEDro database, in February 2012. We selected randomised controlled trials (RCTs) of adults with MSCC of interventions on positioning (mobilisation) and bracing. Two review authors independently assessed each possible study for inclusion and quality. For the original version of the review, we screened 1611 potentially relevant studies. No studies met the inclusion criteria. Many papers identified the importance of mobilisation, but no RCTs of bed rest versus mobilisation have been undertaken. We identified no RCTs of bracing in MSCC.For this update, we identified 347 potential titles. We screened 300 titles and abstracts after removal of duplicates. We did not identify any additional studies for inclusion. Since publication of the original version of this review, no new studies were found and our conclusions remain unchanged.There is a lack of evidence-based guidance around how to correctly position and when to mobilise patients with MSCC or if spinal bracing is an effective technique for reducing pain or improving quality of life. RCTs are required in this important area.

To systematically examine the literature describing the methods by which technical competence is assessed in surgical trainees. The last decade has witnessed an evolution away from time-based surgical education. In response, governing bodies worldwide have implemented competency-based education paradigms. The definition of competence, however, remains elusive, and the impact of these education initiatives in terms of assessment methods remains unclear. A systematic review examining the methods by which technical competence is assessed was conducted by searching MEDLINE, EMBASE, PsychINFO, and the Cochrane database of systematic reviews. Abstracts of retrieved studies were reviewed and those meeting inclusion criteria were selected for full review. Data were retrieved in a systematic manner, the validity and reliability of the assessment methods was evaluated, and quality was assessed using the Grading of Recommendations Assessment, Development and Evaluation classification. Of the 6814 studies identified, 85 studies involving 2369 surgical residents were included in this review. The methods used to assess technical competence were categorized into 5 groups; Likert scales (37), benchmarks (31), binary outcomes (11), novel tools (4), and surrogate outcomes (2). Their validity and reliability were mostly previously established. The overall Grading of Recommendations Assessment, Development and Evaluation for randomized controlled trials was high and low for the observational studies. The definition of technical competence continues to be debated within the medical literature. The methods used to evaluate technical competence predominantly include instruments that were originally created to assess technical skill. Very few studies identify standard setting approaches that differentiate competent versus noncompetent performers; subsequently, this has been identified as an area with great research potential.

2009-01-01

Objective Patients suspected of having swallowing disorders, could highly benefit from simple diagnostic screening before being referred to specialist evaluations. The article analyzes various instrumental methods of dysphagia assessment, introduces surface electromyography (sEMG) to carry out rapid assessment of such patients, and debates proposed suggestions for sEMG screening protocol in order to identify abnormal deglutition. Data sources Subject related books and articles from 1813 to 2007 were obtained through library search, MEDLINE (1949–2007) and EMBASE (1975–2007). Methods Specifics steps for establishing the protocol for applying the technique for screening purposes (e.g., evaluation of specific muscles), the requirements for diagnostic sEMG equipment, the sEMG technique itself, and defining the tests suitable for assessing deglutition (e.g., saliva, normal, and excessive swallows and uninterrupted drinking of water) are presented in detail. SEMG is compared with other techniques in terms of cost, timing, involvement of radiation, etc. Results According to the published data, SEMG of swallowing is a simple and reliable method for screening and preliminary differentiation among dysphagia and odynophagia of various origins. This noninvasive radiation-free examination has a low level of discomfort, and is simple, time-saving and inexpensive to perform. The major weakness of the method seems to be inability for precise diagnostic of neurologically induced dysphagia. Conclusion With standardization of the technique and an established normative database, sEMG might serve as a reliable screening method for optimal patient management but cannot serve for proper investigation of neurogenic dysphagia.

Consensus group methods, such as the Delphi method and nominal group technique (NGT), are used to synthesize expert opinions when evidence is lacking. Despite their extensive use, these methods are inconsistently applied. Their use in medical education research has not been well studied. The authors set out to describe the use of consensus methods in medical education research and to assess the reporting quality of these methods and results. Using scoping review methods, the authors searched the Medline, Embase, PsycInfo, PubMed, Scopus, and ERIC databases for 2009-2016. Full-text articles that focused on medical education and the keywords Delphi, RAND, NGT, or other consensus group methods were included. A standardized extraction form was used to collect article demographic data and features reflecting methodological rigor. Of the articles reviewed, 257 met the inclusion criteria. The Modified Delphi (105/257; 40.8%), Delphi (91/257; 35.4%), and NGT (23/257; 8.9%) methods were most often used. The most common study purpose was curriculum development or reform (68/257; 26.5%), assessment tool development (55/257; 21.4%), and defining competencies (43/257; 16.7%). The reporting quality varied, with 70.0% (180/257) of articles reporting a literature review, 27.2% (70/257) reporting what background information was provided to participants, 66.1% (170/257) describing the number of participants, 40.1% (103/257) reporting if private decisions were collected, 37.7% (97/257) reporting if formal feedback of group ratings was shared, and 43.2% (111/257) defining consensus a priori. Consensus methods are poorly standardized and inconsistently used in medical education research. Improved criteria for reporting are needed.

Systematic literature review. Diastasis of the rectus abdominis muscle (DRAM) has been linked with low back pain, abdominal and pelvic dysfunction. Measurement is used to either screen or to monitor DRAM width. Determining which methods are suitable for screening and monitoring DRAM is of clinical value. To identify the best methods to screen for DRAM presence and monitor DRAM width. AMED, Embase, Medline, PubMed and CINAHL databases were searched for measurement property studies of DRAM measurement methods. Population characteristics, measurement methods/procedures and measurement information were extracted from included studies. Quality of all studies was evaluated using 'quality rating criteria'. When possible, reliability generalisation was conducted to provide combined reliability estimations. Thirteen studies evaluated measurement properties of the 'finger width'-method, tape measure, calipers, ultrasound, CT and MRI. Ultrasound was most evaluated. Methodological quality of these studies varied widely. Pearson's correlations of r = 0.66-0.79 were found between calipers and ultrasound measurements. Calipers and ultrasound had Intraclass Correlation Coefficients (ICC) of 0.78-0.97 for test-retest, inter- and intra-rater reliability. The 'finger width'-method had weighted Kappa's of 0.73-0.77 for test-retest reliability, but moderate agreement (63%; weighted Kappa = 0.53) between raters. Comparing calipers and ultrasound, low measurement error was found (above the umbilicus), and the methods had good agreement (83%; weighted Kappa = 0.66) for discriminative purposes. The available information support ultrasound and calipers as adequate methods to assess DRAM. For other methods limited measurement information of low to moderate quality is available and further evaluation of their measurement properties is required. Copyright © 2015 Elsevier Ltd.

Mixed methods research, the use of both qualitative and quantitative methods within 1 program of study, is becoming increasingly popular to allow investigators to explore patient experiences (qualitative) and also measure outcomes (quantitative). Coronary artery disease and its risk factors are some of the most studied conditions; however, the extent to which mixed methods studies are being conducted in these content areas is unknown. We sought to comprehensively describe the characteristics of published mixed methods studies on coronary artery disease and major risk factors (diabetes mellitus and hypertension). We conducted a scoping review of the literature indexed in PubMed, Medline, EMBASE, and CINAHL. We identified 811 abstracts for screening, of which 254 articles underwent full-text review and 97 reports of 81 studies met criteria for inclusion. The majority of studies in this area were conducted in the past 10 years by nurse researchers from the United States and United Kingdom. Diabetes mellitus was the most common content area for mixed methods investigation (compared with coronary artery disease and hypertension). Most authors described their rationale for using mixed methods as complementarity and did not describe study priority or how they reconciled differences in methodological paradigms. Some mixed methods study designs were more commonly used than others, including concurrent timing and integration at the interpretation stage. Qualitative strands were most commonly descriptive studies using interviews for data collection. Quantitative strands were most commonly cross-sectional observational studies, which relied heavily on self-report data such as surveys and scales. Although mixed methods research is becoming increasingly popular in the area of coronary artery disease and its risk factors, many of the more advanced mixed methods, qualitative, and quantitative techniques have not been commonly used in these areas. © 2016 American Heart Association, Inc.

Forecasting can support rational decision-making around the introduction and use of emerging health technologies and prevent investment in technologies that have limited long-term potential. However, forecasting methods need to be credible. We performed a systematic search to identify the methods used in forecasting studies to predict future health technologies within a 3-20-year timeframe. Identification and retrospective assessment of such methods potentially offer a route to more reliable prediction. Systematic search of the literature to identify studies reported on methods of forecasting in healthcare. People are not needed in this study. The authors searched MEDLINE, EMBASE, PsychINFO and grey literature sources, and included articles published in English that reported their methods and a list of identified technologies. Studies reporting methods used to predict future health technologies within a 3-20-year timeframe with an identified list of individual healthcare technologies. Commercially sponsored reviews, long-term futurology studies (with over 20-year timeframes) and speculative editorials were excluded. 15 studies met our inclusion criteria. Our results showed that the majority of studies (13/15) consulted experts either alone or in combination with other methods such as literature searching. Only 2 studies used more complex forecasting tools such as scenario building. The methodological fundamentals of formal 3-20-year prediction are consistent but vary in details. Further research needs to be conducted to ascertain if the predictions made were accurate and whether accuracy varies by the methods used or by the types of technologies identified.

Objective. To investigate the effects of Jianpi Bushen (JPBS), a traditional Chinese medicine that is used to invigorate the spleen and tonify the kidney, combined with chemotherapy for the treatment of gastric cancer. Methods. Literature retrieval was performed in PubMed, EMBASE, Cochrane Library, MEDLINE, CNKI, Wanfang Data Information Site, and VIP from inception to October 2017. Randomized controlled trials to evaluate the effects of JPBS combined with chemotherapy were identified. The primary reported outcomes were KPS (Karnofsky Performance Status), clinical curative efficiency, immune function, blood system, and nonhematologic system. Review Manager 5.3 (RevMan 5.3) was used for data analysis, and the quality of the studies was also appraised. Results. A total of 26 studies were included with 3098 individuals. The results of the meta-analysis indicated that treatment of gastric cancer with the combination of JPBS and chemotherapy resulted in better outcomes compared to chemotherapy alone. Conclusion. Evidence from the meta-analysis suggested that JPBS combined with chemotherapy has a positive effect on gastric cancer treatment. However, additional rigorously designed and large sample randomized controlled trials are required to confirm the efficacy and safety of this treatment. PMID:29675052

Using patients' charts to assess medical trainees in the workplace: a systematic review.

2015-04-01

The objective of this review is to summarize and critically appraise existing evidence on the use of chart stimulated recall (CSR) and case-based discussion (CBD) as an assessment tool for medical trainees. Medline, Embase, CINAHL, PsycINFO, Educational Resources Information Centre (ERIC), Web of Science, and the Cochrane Central Register of Controlled Trials were searched for original articles on the use of CSR or CBD as an assessment method for trainees in all medical specialties. Four qualitative and three observational non-comparative studies were eligible for this review. The number of patient-chart encounters needed to achieve sufficient reliability varied across studies. None of the included studies evaluated the content validity of the tool. Both trainees and assessors expressed high level of satisfaction with the tool; however, inadequate training, different interpretation of the scoring scales and skills needed to give feedback were addressed as limitations for conducting the assessment. There is still no compelling evidence for the use of patient's chart to evaluate medical trainees in the workplace. A body of evidence that is valid, reliable, and documents the educational effect in support of the use of patients' charts to assess medical trainees is needed.

Review Article: Celiac Disease, New Approaches to Therapy

Rashtak, Shahrooz; Murray, Joseph A

2014-01-01

STRUCTURED SUMMARY Background Celiac disease is managed by life-long gluten withdrawal from the diet. However strict adherence to a gluten-free diet is difficult and is not always effective. Novel therapeutic approaches are needed to supplement or even replace the dietary treatment. Aims To review recent advances in new therapeutic options for celiac disease. Methods A literature search was performed on MEDLINE, EMBASE, Web of Science, Scopus, DDW.org and ClinicalTrial.gov for English articles and abstracts. The search terms used include but not limited to “Celiac disease”, “new”, “novel”, Advances”, “alternatives” and “Drug therapy”. The cited articles were selected based on the relevancy to the review objective. Results Several new therapeutic approaches for celiac disease are currently under development by targeting its underlying pathogenesis. Alternative therapies range from reproduction of harmless wheat strains to immunomodulatory approaches. Some of these therapies such as enzymatic cleavage of gluten and permeability inhibitors have shown promise in clinical studies. Conclusion Gluten-free diet is still the only practical treatment for patients with celiac disease. Novel strategies provide promise of alternative adjunctive approaches to diet restriction alone for patients with this disorder. PMID:22324389

Objective To determine the effect of adjunctive antithyroid drugs on the risk of treatment failure, hypothyroidism, and adverse events after radioiodine treatment. Design Meta-analysis. Data sources Electronic databases (Cochrane central register of controlled trials, Medline, Embase) searched to August 2006 and contact with experts. Review methods Three reviewers independently assessed trial eligibility and quality. Pooled relative risks for treatment failure and hypothyroidism after radioiodine treatment with and without adjunctive antithyroid drugs were calculated with a random effects model. Results We identified 14 relevant randomised controlled trials with a total of 1306 participants. Adjunctive antithyroid medication was associated with an increased risk of treatment failure (relative risk 1.28, 95% confidence interval 1.07 to 1.52; P=0.006) and a reduced risk for hypothyroidism (0.68, 0.53 to 0.87; P=0.006) after radioiodine treatment. We found no difference in summary estimates for the different antithyroid drugs or for whether antithyroid drugs were given before or after radioiodine treatment. Conclusions Antithyroid drugs potentially increase rates of failure and reduce rates of hypothyroidism if they are given in the week before or after radioiodine treatment, respectively.

Background Pre-eclampsia is associated with several complications. Early prediction of complications and timely management is needed for clinical care of these patients to avert fetal and maternal mortality and morbidity. There is a need to identify best testing strategies in pre eclampsia to identify the women at increased risk of complications. We aim to determine the accuracy of various tests to predict complications of pre-eclampsia by systematic quantitative reviews. Method We performed extensive search in MEDLINE (1951–2004), EMBASE (1974–2004) and also will also include manual searches of bibliographies of primary and review articles. An initial search has revealed 19500 citations. Two reviewers will independently select studies and extract data on study characteristics, quality and accuracy. Accuracy data will be used to construct 2 × 2 tables. Data synthesis will involve assessment for heterogeneity and appropriately pooling of results to produce summary Receiver Operating Characteristics (ROC) curve and summary likelihood ratios. Discussion This review will generate predictive information and integrate that with therapeutic effectiveness to determine the absolute benefit and harm of available therapy in reducing complications in women with pre-eclampsia.

Introduction Acne vulgaris affects over 80% of teenagers, and persists beyond the age of 25 years in 3% of men and 12% of women. Typical lesions of acne include comedones, inflammatory papules, and pustules. Nodules and cysts occur in more severe acne and can cause scarring and psychological distress. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical question: What are the effects of topical and oral treatments in people with acne vulgaris? We searched: Medline, Embase, The Cochrane Library, and other important databases up to February 2010 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 69 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review we present information relating to the effectiveness and safety of the following interventions: topical treatments (adapalene, azelaic acid, benzoyl peroxide, clindamycin, erythromycin [alone or plus zinc]; isotretinoin, tetracycline, tretinoin); and oral treatments (doxycycline, isotretinoin, lymecycline, minocycline, oxytetracycline, tetracycline).

Aim The purpose of this systematic literature review is to assess the benefits of workplace-based occupational therapies and interventions, including acute and preventive medication, on headache intensity and frequency, related disability as well as work-related outcomes. Methods A search of the literature was conducted in PubMed, MEDLINE, Cochrane library, CINAHL and Embase using terms related to headache, workplace and occupational health. The Cochrane Collaboration's risk of bias assessment tool was used on individual studies to assess internal validity and the Grading of Recommendations Assessment, Development, and Evaluation system was applied to studies by clinical outcome and used to rate quality of evidence. Results Fifteen articles were included in the systematic review. None of them were classified as low risk of bias according to the Cochrane Collaboration's tool for assessing risk of bias. This systematic review found preliminary low-quality evidence suggesting that exercise and acupuncture can reduce workers' headache pain intensity, frequency and related disability. Conclusion Although this systematic review provided preliminary low evidence in favour of work-based intervention, studies with more rigorous designs and methodologies are needed to provide further evidence of the effectiveness of workplace-based headache management strategies.

Abstract Objective: The aim of this review is to synthesize the evidence on the effects of aquatic exercise interventions on physical function and fitness among people with spinal cord injury. Data source: Six major databases were searched from inception till June 2015: MEDLINE, CINAHL, EMBASE, PsychInfo, SPORTDiscus, and Cochrane Center Register of Controlled Trials. Study appraisal and synthesis methods: Two reviewers independently rated methodological quality using the modified Downs and Black Scale and extracted and synthesized key findings (i.e., participant characteristics, study design, physical function and fitness outcomes, and adverse events). Results: Eight of 276 studies met the inclusion criteria, of which none showed high research quality. Four studies assessed physical function outcomes and 4 studies evaluated aerobic fitness as outcome measures. Significant improvements on these 2 outcomes were generally found. Other physical or fitness outcomes including body composition, muscular strength, and balance were rarely reported. Conclusions and implications of key findings: There is weak evidence supporting aquatic exercise training to improve physical function and aerobic fitness among adults with spinal cord injury. Suggestions for future research include reporting details of exercise interventions, evaluating other physical or fitness outcomes, and improving methodological quality. PMID:28296754

2018-01-01

In recent years, studies have increasingly employed data logger technologies to record objective driving and physiological characteristics of manual wheelchair users. However, the technologies used offer significant differences in characteristics, such as measured outcomes, ease of use, and level of burden. In order to identify and describe the extent of published research activity that relies on data logger technologies for manual wheelchair users, we performed a scoping review of the scientific and gray literature. Five databases were searched: Medline, Compendex, CINAHL, EMBASE, and Google Scholar. The 119 retained papers document a wide variety of logging devices and sensing technologies measuring a range of outcomes. The most commonly used technologies were accelerometers installed on the user (18.8%), odometers installed on the wheelchair (12.4%), accelerometers installed on the wheelchair (9.7%), and heart monitors (9.7%). Not surprisingly, the most reported outcomes were distance, mobility events, heart rate, speed/velocity, acceleration, and driving time. With decreasing costs and technological improvements, data loggers are likely to have future widespread clinical (and even personal) use. Future research may be needed to assess the usefulness of different outcomes and to develop methods more appropriate to wheelchair users in order to optimize the practicality of wheelchair data loggers.

Defining patient-centred care in dentistry? A systematic review of the dental literature.

2016-10-21

Objective This paper presents the results of a systematic review, designed to explore how patient-centred care (PCC) is defined in the dental literature.Method An electronic search of MEDLINE (1946-2012), Embase (1980-2012) PsycINFO (1806-2012), the Cochrane Library and non-peer reviewed literature was conducted using a standardised search protocol. Definitions of patient centred care were identified and scored on two criteria to evaluate quality of definition and quality/type of evidence.Results Of the 28 papers included in the review the majority provided definitions of PCC synonymous with good quality general care (holistic, humanitarian). Only three mentioned the provision of information and the tools to facilitate informed choice. Less than a third of the papers included in this review were based on empirical evidence, and of those that were, only one was an RCT study.Conclusion The evidence suggests that the concept of PCC is neither clearly understood nor empirically and systematically assessed in dental settings. Whilst most authors seem to suggest that PCC is about delivering care that is humane, involving good communication and shared decision-making, there is no work assessing these concepts empirically or relating them to practical outcomes.

Aloe vera: a systematic review of its clinical effectiveness.

PubMed Central

Vogler, B K; Ernst, E

1999-01-01

BACKGROUND: The use of aloe vera is being promoted for a large variety of conditions. Often general practitioners seem to know less than their patients about its alleged benefits. AIM: To define the clinical effectiveness of aloe vera, a popular herbal remedy in the United Kingdom. METHOD: Four independent literature searches were conducted in MEDLINE, EMBASE, Biosis, and the Cochrane Library. Only controlled clinical trials (on any indication) were included. There were no restrictions on the language of publication. All trials were read by both authors and data were extracted in a standardized, pre-defined manner. RESULTS: Ten studies were located. They suggest that oral administration of aloe vera might be a useful adjunct for lowering blood glucose in diabetic patients as well as for reducing blood lipid levels in patients with hyperlipidaemia. Topical application of aloe vera is not an effective preventative for radiation-induced injuries. It might be effective for genital herpes and psoriasis. Whether it promotes wound healing is unclear. There are major caveats associated with all of these statements. CONCLUSION: Even though there are some promising results, clinical effectiveness of oral or topical aloe vera is not sufficiently defined at present. PMID:10885091

Long-term results after treatment of extensive odontogenic cysts of the jaws: a review.

Wakolbinger, Robert; Beck-Mannagetta, Johann

2016-01-01

The aim was to perform a literature review concerning long-term results after treatment of extensive cysts of the jaws. The following databases were searched: MEDLINE, Cochrane CENTRAL, Cochrane Database of Systematic Reviews, The Cochrane Library, and EMBASE. Case reports and abstracts were excluded. Three hundred fifty-six articles were found, of which 30 were included. Only the minority of the studies reported long-term results. Most authors did not distinguish between temporary complications and permanent deficiencies (incomplete bone healing, permanent sensory deficits). Based on this review, it is recommended to consider primary decompression or marsupialization ± later definitive surgery for the treatment of extensive jaw cysts in order to achieve satisfying clinical results. Complications (occurring within the first 6 months postoperatively, e.g., infection) and remaining deficits (after a minimum of 6 months and not changing over time, e.g., bony or sensory deficit) should be clearly separated from each other. Knowledge of permanent deficits and bone healing after different therapeutic approaches is important for decision making. Patients should be informed not only about complications but also about the risk of permanent deficits for each method.

Introduction The evidence linking dietary intake with diabetic retinopathy (DR) is growing but unclear. We conducted a systematic review of the association between dietary intake and DR. Methods We systematically searched PubMed, Embase, Medline, and the Cochrane Central register of controlled trials, for publications between January 1967 and January 2017 using standardized criteria for diet and DR. Interventional and observational studies investigating micro- and macro-nutrient intakes; food and beverage consumptions; and dietary patterns were included. Study quality was evaluated using a modified Newcastle-Ottawa scale for observational studies, and the Cochrane collaboration tool for interventional studies. Results Of 4265 titles initially identified, 31 studies (3 interventional, 28 Observational) were retained. Higher intakes of dietary fibre, oily fish, and greater adherence to a Mediterranean diet were protective of DR. Conversely, high total caloric intake was associated with higher risk of DR. No significant associations of carbohydrate, vitamin D, and sodium intake with DR were found. Associations of antioxidants, fatty acids, proteins and alcohol with DR remain equivocal. Conclusions Dietary fibre, oily fish, a Mediterranean diet and a reduced caloric intake are associated with lower risk of DR. Longitudinal data and interventional models are warranted to confirm our findings and better inform clinical guidelines. PMID:29324740

Introduction The inadvertent or purposeful introduction of foreign bodies or substances can lead to cerebral infarction if they embolize to the brain. Individual reports of these events are uncommon but may increase with the increased occurrences of their risk factors, for example, intra-arterial procedures. Method We searched EMBASE and MEDLINE for articles on embolic stroke of nontissue origin. 1889 articles were identified and screened and 216 articles were ultimately reviewed in full text and included in qualitative analysis. Articles deemed relevant were assessed by a second reviewer to confirm compatibility with the inclusion criteria. References of included articles were reviewed for relevant publications. We categorized the pathology of the emboli into the following groups: air embolism (141 reports), other arterial gas embolisms (49 reports), missiles and foreign bodies (16 reports), and others, including drug embolism, cotton wool, and vascular sclerosant agents. Conclusion Air and gaseous embolism are becoming more common with increased use of interventional medical procedures and increased popularity of sports such as diving. There is increasing evidence for the use of hyperbaric oxygen for such events. Causes of solid emboli are diverse. More commonly reported causes include bullets, missiles, and substances used in medical procedures. PMID:29123937

2017-06-01

Background The increasing prevalence of virtual reality simulation in temporal bone surgery warrants an investigation to assess training effectiveness. Objectives To determine if temporal bone simulator use improves mastoidectomy performance. Data Sources Ovid Medline, Embase, and PubMed databases were systematically searched per the PRISMA guidelines. Review Methods Inclusion criteria were peer-reviewed publications that utilized quantitative data of mastoidectomy performance following the use of a temporal bone simulator. The search was restricted to human studies published in English. Studies were excluded if they were in non-peer-reviewed format, were descriptive in nature, or failed to provide surgical performance outcomes. Meta-analysis calculations were then performed. Results A meta-analysis based on the random-effects model revealed an improvement in overall mastoidectomy performance following training on the temporal bone simulator. A standardized mean difference of 0.87 (95% CI, 0.38-1.35) was generated in the setting of a heterogeneous study population ( I 2 = 64.3%, P < .006). Conclusion In the context of a diverse population of virtual reality simulation temporal bone surgery studies, meta-analysis calculations demonstrate an improvement in trainee mastoidectomy performance with virtual simulation training.

Objective: Suicide is a significant public health issue, and is especially concerning in adolescents and young adults, who are over-represented both in attempts and completed suicide. Emerging technologies represent a promising new approach to deliver suicide prevention interventions to these populations. The current systematic review aims to identify online and mobile psychosocial suicide prevention interventions for young people, and evaluate the effectiveness of these interventions. Method: PsycINFO, Medline, Embase and The Cochrane Library were electronically searched for all articles published between January, 2000 and May, 2015. Peer-reviewed journal articles reporting on interventions for young people aged 12–25 years with suicidality as a primary outcome were eligible for inclusion. No exclusions were placed on study design. Results: One study met inclusion criteria, and found significant reductions in the primary outcome of suicidal ideation, as well as depression and hopelessness. Two relevant protocol papers of studies currently underway were also identified. Conclusions: There is a paucity of current evidence for online and mobile interventions for suicide prevention in youth. More high quality empirical evidence is required to determine the effectiveness of these novel approaches to improving suicide outcomes in young people. PMID:27274742

Grazing, a type of maladaptive eating behavior, has been associated with poor weight outcomes in bariatric patients. The purpose of this study was to conduct a systematic review of the association between grazing behavior and weight regain post-bariatric surgery. Literature searches, study selection, design of the method, and quality appraisal were carried out by two independent authors. The search strategy was performed until October 2017 in Medline, Embase, Cochrane, Lilacs, Scopus, Web of Science, Google Scholar, ProQuest Dissertation & Theses, and Open Grey. Of a total of 3764 articles, five papers met the inclusion criteria (four original articles and one thesis), comprising 994 subjects, mostly women. The prevalence of grazing behavior ranged from 16.6 to 46.6%, and the highest prevalence of significant weight regain was 47%. The association between grazing and weight regain was observed in four of the five evaluated studies. Our findings support an association between grazing behavior and weight regain after bariatric surgery, regardless of surgery type and contextual concept of grazing. Further studies are needed to confirm the clarity of the real prevalence and interfering factors related to grazing behavior and weight outcomes.

This review examined the impact of environmental change and educational interventions targeting young children from minority groups living in urban environments and who were from low-income families. A scoping methodology was used to find research across six databases, including CINAHL, ERIC, PsycINFO, PubMed, MEDLINE, and EMBASE. 299 studies were identified. Duplicates were removed leaving 159 studies. After reviewing for inclusion and exclusion criteria, 23 manuscripts were identified for this study: 11 featured home-environment change interventions and 12 emphasized education of children. Studies were reviewed to determine key interventions and outcomes for children. Both environmental interventions and educational programs had positive outcomes. Interventions did not always impact health outcomes, such as emergency department visits. Results indicated many of the environmental change and education interventions improved asthma management and some symptoms. A multipronged approach may be a good method for targeting both education and change in the home and school environment to promote the well-being of young children in urban areas. New research with careful documentation of information about study participants, dose of intervention (i.e., number and duration of sessions, booster sessions) and specific intervention components also will provide guidance for future research.

Background . Although numerous studies have shown that plasma fibrinogen is linked to renal cell carcinoma (RCC) risk, the consistency and magnitude of the effect of plasma fibrinogen are unclear. The aim of the study was to explore the association between plasma fibrinogen and RCC prognosis. Methods . An electronic search of Embase, PubMed/MEDLINE, and the Cochrane databases was performed to identify relevant studies published prior to June 1, 2016. Results . A total of 3744 patients with RCC from 7 published studies were included in the meta-analysis. The prognostic and clinical relevance of plasma fibrinogen are evaluated in RCC patients. Statistical significance of the combined hazard ratio (HR) was detected for overall survival, cancer-specific survival, and disease-free survival. Our pooled results showed that elevated plasma fibrinogen was significantly associated with clinical stage and Fuhrman grading. The level of plasma fibrinogen was not found to be associated with tumor type and gender. Conclusions . Elevated plasma fibrinogen is a strong indicator of poorer prognosis of patients with RCC, whereas the plasma fibrinogen is not significantly associated with tumor type. Therefore, plasma fibrinogen could be used in patients with RCC for risk stratification and decision providing a proper therapeutic strategy.

2012-08-01

To systematically review the value of apparent diffusion coefficient (ADC) measurement in the differentiation between benign and malignant lesions. A systematic search of the Medline/Pubmed and Embase databases revealed 109 relevant studies. Quality of these articles was assessed using the Quality Assessment of the Studies of Diagnostic Accuracy Included in Systematic Reviews (QUADAS) criteria. Reported ADC values of benign and malignant lesions were compared per organ. The mean quality score of the reviewed articles was 50%. Comparison of ADC values showed marked variation among studies and between benign and malignant lesions in various organs. In several organs, such as breast, liver, and uterus, ADC values discriminated well between benign and malignant lesions. In other organs, such as the salivary glands, thyroid, and pancreas, ADCs were not significantly different between benign and malignant lesions. The potential utility of ADC measurement for the characterisation of tumours differs per organ. Future well-designed studies are required before ADC measurements can be recommended for the differentiation of benign and malignant lesions. These future studies should use standardised acquisition protocols and provide complete reporting of study methods, to facilitate comparison of results and clinical implementation of ADC measurement for tumour characterisation.

Introduction Skin disorders associated with photodamage from ultraviolet light include wrinkles, hyperpigmentation, tactile roughness, and telangiectasia, and are more common in people with white compared with other skin types. Wrinkles are also associated with ageing, hormonal status, smoking, and intercurrent disease. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical question: What are the effects of interventions to prevent and treat skin wrinkles? We searched: Medline, Embase, The Cochrane Library, and other important databases up to April 2008 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 20 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review we present information relating to the effectiveness and safety of the following interventions: alpha and beta hydroxyl acids, carbon dioxide laser, chemical peel, dermabrasion, facelifts, isotretinoin, natural cartilage polysaccharides (oral or topical), retinyl esters, sunscreens, tazarotene, tretinoin, variable pulse erbium:YAG laser, and vitamin C or E (topical).

ABSTRACT Purpose: Physical activity (PA) has been suggested to help increase the survival of individuals with cancer. The objective of this review was to systematically evaluate and summarize the available evidence investigating the effect of PA on the survival of individuals with cancer. Methods: Electronic databases (CINAHL, EMBASE, and MEDLINE) were systematically searched for randomized controlled trials and cohort studies. Selected studies were assessed by two independent investigators for methodological quality, using the PEDro scale. Results: Ten prospective cohort studies met the inclusion criteria. Quality-assessment scores averaged 5/10 on the PEDro scale, with two articles obtaining a score of 6/10. The majority of studies found that individuals participating in higher levels of physical activity had a reduced risk of cancer-related mortality. This trend was observed specifically for breast, colon, and colorectal cancers. On average, it appears that engaging in higher levels of metabolic equivalent hours per week may help to improve survival rates among individuals diagnosed with cancer. Conclusion: Patients diagnosed with cancer demonstrated a trend toward increased survival with greater levels of PA. However, because only prospective cohort studies were included in the study, the conclusions drawn should be regarded with caution. PMID:21197176

Background Overweight and obesity are thought to significantly influence a person's risk of cardiovascular disease, possibly via its effect on the microvasculature. Retinal vascular caliber is a surrogate marker of microvascular disease and a predictor of cardiovascular events. The aim of this systematic review and meta-analysis was to determine the association between body mass index (BMI) and retinal vascular caliber. Methods and Findings Relevant studies were identified by searches of the MEDLINE and EMBASE databases from 1966 to August 2011. Standardized forms were used for data extraction. Among over 44,000 individuals, obese subjects had narrower arteriolar and wider venular calibers when compared with normal weight subjects, independent of conventional cardiovascular risk factors. In adults, a 1 kg/m2 increase in BMI was associated with a difference of 0.07 μm [95% CI: −0.08; −0.06] in arteriolar caliber and 0.22 μm [95% CI: 0.21; 0.23] in venular caliber. Similar results were found for children. Conclusions Higher BMI is associated with narrower retinal arteriolar and wider venular calibers. Further prospective studies are needed to examine whether a causative relationship between BMI and retinal microcirculation exists. PMID:23405065

Upregulating substance P levels to treat obstructive sleep apnea.

PubMed

Ursavas, Ahmet

2008-05-01

The neuropeptide (tachykinin) substance P is widely distributed in the central and peripheral nervous systems. Substance P has been suggested to function as a neurotransmitter, cotransmitter, or neuromodulator in the central and peripheral nervous system. substance P also influences sleep physiology. Neurokinin 1 (NK-1) receptors may also be implicated in the control of sleep/wake behavior. Obstructive sleep apnea syndrome (OSAS) is defined as repeated episodes of upper airway occlusion during sleep with subsequent excessive daytime sleepiness (EDS). Substance P levels are found to be significantly lowered in patients with OSAS. The aim of this review was to investigate the relationship between substance P, EDS and other OSAS complications. The literature was searched using standard methods. Medline and Embase were searched systematically from 1974 to the end of February 2008 for relevant articles published in English. EDS seen in some OSAS patients may be associated with various pathophysiological mechanisms including changes in substance P levels. Intravenous substance P administration in OSAS patients can be effective in the treatment of EDS. Further studies on the possible relationship between low serum substance P and hypertension, reproductive function disorders, memory and learning problems in OSAS cases is required.

Background: Mindfulness- and acceptance-based interventions are increasingly studied as a potential treatment for a variety of mental conditions. Objective: To assess the effects of mindfulness- and acceptance-based interventions on psychotic symptoms and hospitalization in patients with psychosis Methods: MEDLINE/PubMed, Embase, the Cochrane Library, and PsycINFO were screened from inception through April 2015. Randomized controlled trials (RCTs) were analyzed when they assessed psychotic symptoms or hospitalization in patients with psychosis; affect, acceptance, mindfulness, and safety were defined as secondary outcomes. Results: Eight RCTs with a total of 434 patients comparing mindfulness-based (4 RCTs) or acceptance-based interventions (4 RCTs) to treatment as usual or attention control were included. Six RCTs had low risk of bias. Moderate evidence was found for short-term effects on total psychotic symptoms, positive symptoms, hospitalization rates, duration of hospitalization, and mindfulness and for long-term effects on total psychotic symptoms and duration of hospitalization. No evidence was found for effects on negative symptoms, affect, or acceptance. No serious adverse events were reported. Conclusion: Mindfulness- and acceptance-based interventions can be recommended as an additional treatment for patients with psychosis. PMID:26937312

Effects of technical editing in biomedical journals: a systematic review.

Wager, Elizabeth; Middleton, Philippa

2002-06-05

Technical editing supposedly improves the accuracy and clarity of journal articles. We examined evidence of its effects on research reports in biomedical journals. Subset of a systematic review using Cochrane methods, searching MEDLINE, EMBASE, and other databases from earliest entries to February 2000 by using inclusive search terms; hand searching relevant journals. We selected comparative studies of the effects of editorial processes on original research articles between acceptance and publication in biomedical journals. Two reviewers assessed each study and performed independent data extraction. The 11 studies on technical editing indicate that it improves the readability of articles slightly (as measured by Gunning Fog and Flesch reading ease scores), may improve other aspects of their quality, can increase the accuracy of references and quotations, and raises the quality of abstracts. Supplying authors with abstract preparation instructions had no discernible effect. Considering the time and resources devoted to technical editing, remarkably little is know about its effects or the effects of imposing different house styles. Studies performed at 3 journals employing relatively large numbers of professional technical editors suggest that their editorial processes are associated with increases in readability and quality of articles, but these findings may not be generalizable to other journals.

As clinical practice guidelines represent the most important evidence-based decision support tool, several strategies have been applied to improve their implementation into the primary health care system. This study aimed to evaluate the effect of intervention methods on the guideline adherence of primary care providers (PCPs). The studies selected through a systematic search in Medline and Embase were categorised according to intervention schemes and outcome indicator categories. Harvest plots and forest plots were applied to integrate results. The 36 studies covered six intervention schemes, with single interventions being the most effective and distribution of materials the least. The harvest plot displayed 27 groups having no effect, 14 a moderate and 21 a strong effect on the outcome indicators in the categories of knowledge transfer, diagnostic behaviour, prescription, counselling and patient-level results. The forest plot revealed a moderate overall effect size of 0.22 [0.15, 0.29] where single interventions were more effective (0.27 [0.17, 0.38]) than multifaceted interventions (0.13 [0.06, 0.19]). Guideline implementation strategies are heterogeneous. Reducing the complexity of strategies and tailoring to the local conditions and PCPs' needs may improve implementation and clinical practice.

Background. Tetrahydrobiopterin (BH4) is a cofactor of nitric oxide synthase (NOS). Nitric oxide (NO) bioavailability is reduced during the early stage of vascular diseases, such as coronary artery disease, hypercholesterolemia, hypertension, and diabetic vasculopathy, and even throughout the entire progression of atherosclerosis. Methods. A literature search was performed using electronic databases (up to January 31, 2014), including MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL), using an established strategy. Results. Fourteen articles were selected with a total of 370 patients. Ten of the fourteen studies showed a significant improvement in the endothelial dysfunction of various cardiovascular disease groups with BH4 supplementation compared with the control groups or placebos. Three studies showed no positive outcome, and one study showed that low-dose BH4 had no effect but that high-dose BH4 did have a significantly different result. Conclusions. This review concludes that supplementation with BH4 and/or augmentation of the endogenous levels of BH4 will be a novel approach to improve the endothelial dysfunction observed in various cardiovascular diseases. BH4 might be considered to be a new therapeutic agent to prevent the initiation and progression of cardiovascular disease. PMID:25548592

2014-01-01

Background. Acupuncture has been shown to reduce preoperative anxiety in several previous randomized controlled trials (RCTs). In order to assess the preoperative anxiolytic efficacy of acupuncture therapy, this study conducted a meta-analysis of an array of appropriate studies. Methods. Four electronic databases (MEDLINE, EMBASE, CENTRAL, and CINAHL) were searched up to February 2014. In the meta-analysis data were included from RCT studies in which groups receiving preoperative acupuncture treatment were compared with control groups receiving a placebo for anxiety. Results. Fourteen publications (N = 1,034) were included. Six publications, using the State-Trait Anxiety Inventory-State (STAI-S), reported that acupuncture interventions led to greater reductions in preoperative anxiety relative to sham acupuncture (mean difference = 5.63, P < .00001, 95% CI [4.14, 7.11]). Further eight publications, employing visual analogue scales (VAS), also indicated significant differences in preoperative anxiety amelioration between acupuncture and sham acupuncture (mean difference = 19.23, P < .00001, 95% CI [16.34, 22.12]). Conclusions. Acupuncture therapy aiming at reducing preoperative anxiety has a statistically significant effect relative to placebo or nontreatment conditions. Well-designed and rigorous studies that employ large sample sizes are necessary to corroborate this finding. PMID:25254059

Background. The early detection of rheumatic diseases and the treatment to target have become of utmost importance to control the disease and improve its prognosis. However, establishing a diagnosis in early stages is challenging as many diseases initially present with similar symptoms and signs. Expert systems are computer programs designed to support the human decision making and have been developed in almost every field of medicine. Methods. This review focuses on the developments in the field of rheumatology to give a comprehensive insight. Medline, Embase, and Cochrane Library were searched. Results. Reports of 25 expert systems with different design and field of application were found. The performance of 19 of the identified expert systems was evaluated. The proportion of correctly diagnosed cases was between 43.1 and 99.9%. Sensitivity and specificity ranged from 62 to 100 and 88 to 98%, respectively. Conclusions. Promising diagnostic expert systems with moderate to excellent performance were identified. The validation process was in general underappreciated. None of the systems, however, seemed to have succeeded in daily practice. This review identifies optimal characteristics to increase the survival rate of expert systems and may serve as valuable information for future developments in the field.

Purpose the past decade has seen a considerable increase in the use of research models to study reverse total shoulder arthroplasty (RTSA). Nevertheless, none of these models has been shown to completely reflect real in vivo conditions. Methods we performed a systematic review of the literature matching the following key words: “reverse total shoulder arthroplasty” or “reverse total shoulder replacement” or “reverse total shoulder prosthesis” and “research models” or “biomechanical models” or “physical simulators” or “virtual simulators”. The following databases were screened: Medline, Google Scholar, EMBASE, CINAHIL and Ovid. We identified and included all articles reporting research models of any kind, such as physical or virtual simulators, in which RTSA and the glenohumeral joint were reproduced. Results computer models and cadaveric models are the most commonly used, and they were shown to be reliable in simulating in vivo conditions. Bone substitute models have been used in a few studies. Mechanical testing machines provided useful information on stability factors in RTSA. Conclusion because of the limitations of each individual model, additional research is required to develop a research model of RTSA that may reduce the limitations of those presently available, and increase the reproducibility of this technique in the clinical setting.

To systematically review studies measuring the influence of pre-existing disability on the risk of sustaining an injury. Systematic review. Electronic databases searched included Medline (Pubmed), ProQuest, Ovid and EMBASE. Studies (1990-2010) in international peer-reviewed journals were identified with main inclusion criteria being that the study assessed involvement of injury sustained by persons with and without pre-existing disability. Studies were collated by design and methods, and evaluation of results. Twenty-two studies met the inclusion criteria of our review. All studies found that persons with disabilities were at a significantly higher risk of sustaining injuries than those without. Persons with disability had a 30-450% increased odds (odds ratio 1.3-5.5) of sustaining injury compared to persons without disability. Among persons with pre-existing disability, the high risk groups of sustaining an injury are children and elderly. People with disabilities experience a higher risk to sustain an injury in comparison to the healthy population. There is a high need for large epidemiological studies of injury among persons with disability, to better address these unique risk profiles in order to prevent additional disability or secondary conditions.

ABSTRACT Objective: to identify and summarize studies examining both drug-drug interactions (DDI) and adverse drug reactions (ADR) in older adults polymedicated. Methods: an integrative review of studies published from January 2008 to December 2013, according to inclusion and exclusion criteria, in MEDLINE and EMBASE electronic databases were performed. Results: forty-seven full-text studies including 14,624,492 older adults (≥ 60 years) were analyzed: 24 (51.1%) concerning ADR, 14 (29.8%) DDI, and 9 studies (19.1%) investigating both DDI and ADR. We found a variety of methodological designs. The reviewed studies reinforced that polypharmacy is a multifactorial process, and predictors and inappropriate prescribing are associated with negative health outcomes, as increasing the frequency and types of ADRs and DDIs involving different drug classes, moreover, some studies show the most successful interventions to optimize prescribing. Conclusions: DDI and ADR among older adults continue to be a significant issue in the worldwide. The findings from the studies included in this integrative review, added to the previous reviews, can contribute to the improvement of advanced practices in geriatric nursing, to promote the safety of older patients in polypharmacy. However, more research is needed to elucidate gaps. PMID:27598380

The bonding interface of glass ceramics and resin luting cements plays an important role in the long-term durability of ceramic restorations. The purpose of this systematic review is to discuss the various factors involved with the bond between glass ceramics and resin luting cements. An electronic Pubmed, Medline and Embase search was conducted to obtain laboratory studies on resin-ceramic bonding published in English and Chinese between 1972 and 2012. Eighty-three articles were included in this review. Various factors that have a possible impact on the bond between glass ceramics and resin cements were discussed, including ceramic type, ceramic crystal structure, resin luting cements, light curing, surface treatments, and laboratory test methodology. Resin-ceramic bonding has been improved substantially in the past few years. Hydrofluoric acid (HF) etching followed by silanizaiton has become the most widely accepted surface treatment for glass ceramics. However, further studies need to be undertaken to improve surface preparations without HF because of its toxicity. Laboratory test methods are also required to better simulate the actual oral environment for more clinically compatible testing. Copyright © 2014 Academy of Dental Materials.

AIM: To perform a meta-analysis of observational studies and randomized controlled trials (RCTs) on the association between Helicobacter pylori (H. pylori) and iron deficiency anemia (IDA). METHODS: A defined search strategy was used to search Medline, Embase, the Cochrane Library, Clinical Trials, Cochrane Central Register of Controlled Trials, Premedline and Healthstar. Odds ratio (OR) was used to evaluate observational epidemiology studies, and weighted mean difference (WMD) was used to demonstrate the difference between control and intervention groups. RESULTS: Fifteen observational studies and 5 RCTs were identified and used for calculation. The pooled OR for observational studies was 2.22 (95% CI: 1.52-3.24, P < 0.0001). The WMD for hemoglobin (HB) was 4.06 g/L (95% CI: -2.57-10.69, P = 0.01), and the WMD for serum ferritin (SF) was 9.47 μg/L (95% CI: -0.50-19.43, P < 0.0001). Results were heterogeneous for all comparisons. CONCLUSION: This meta-analysis on observational studies suggests an association between H. pylori and IDA. In RCTs, eradication of H. pylori can improve HB and SF levels but not significantly. PMID:20143469

Objective To investigate the evidence-based treatment of catatonia in adults. The secondary aim is to develop a treatment protocol. Materials and methods A systematic review of published treatment articles (case series, cohort or randomized controlled studies) which examined the effects of particular interventions for catatonia and/or catatonic symptoms in adult populations and used valid outcome measures was performed. The articles for this review were selected by searching the electronic databases of the Cochrane Library, MEDLINE, EMBASE and PSYCHINFO. Results Thirty-one articles met the inclusion criteria. Lorazepam and electroconvulsive therapy (ECT) proved to be the most investigated treatment interventions. The response percentages in Western studies varied between 66% and 100% for studies with lorazepam, while in Asian and Indian studies, they were 0% and 100%. For ECT, the response percentages are 59%–100%. There does not seem to be evidence for the use of antipsychotics in catatonic patients without any underlying psychotic disorder. Conclusion Lorazepam and ECT are effective treatments for which clinical evidence is found in the literature. It is not possible to develop a treatment protocol because the evidence for catatonia management on the basis of the articles reviewed is limited. Stringent treatment studies on catatonia are warranted. PMID:29398916

Everyday memory is one of the most affected cognitive functions in multiple sclerosis (MS). Assessing everyday memory problems is crucial for monitoring the impact of memory deficits on individuals' day-to-day lives and evaluating the effectiveness of interventions that aim to improve cognitive functions. The aim of this systematic review was to identify the research literature on everyday memory measures used with people with MS, describe the types of measures used, and summarise their psychometric properties. Empirical studies of cognitive function in MS using standardised everyday memory measures were included. Online databases (MEDLINE, PsycINFO, PsycARTICLES, Embase) and Google Scholar were searched. Forty-four studies met the inclusion criteria. A total of 12 measures were identified, with varied uses and administration methods. The majority of papers did not report any psychometric properties for MS populations. The few papers that did, reported that the measures have good reliability and appear to have good face, concurrent, and ecological validity, but these need to be evaluated further. This review presents researchers and clinicians with an overview of the various everyday memory measures used in studies with people with MS, to help them choose the appropriate measure for their evaluations.

Objective To review the literature on psychological and biological findings on resilience (i.e. the successful adaptation and swift recovery after experiencing life adversities) at the level of the individual, and to integrate findings from animal and human studies. Method Electronic and manual literature search of MEDLINE, EMBASE and PSYCHINFO, using a range of search terms around biological and psychological factors influencing resilience as observed in human and experimental animal studies, complemented by review articles and cross-references. Results The term resilience is used in the literature for different phenomena ranging from prevention of mental health disturbance to successful adaptation and swift recovery after experiencing life adversities, and may also include post-traumatic psychological growth. Secure attachment, experiencing positive emotions and having a purpose in life are three important psychological building blocks of resilience. Overlap between psychological and biological findings on resilience in the literature is most apparent for the topic of stress sensitivity, although recent results suggest a crucial role for reward experience in resilience. Conclusion Improving the understanding of the links between genetic endowment, environmental impact and gene–environment interactions with developmental psychology and biology is crucial for elucidating the neurobiological and psychological underpinnings of resilience.

In systematic reviews of studies of patients' values and preferences, the objective of the study was to summarize items and domains authors have identified when considering the risk of bias (RoB) associated with primary studies. We conducted a systematic survey of systematic reviews of patients' values and preference studies. Our search included three databases (MEDLINE, EMBASE, and PsycINFO) from their inception to August 2015. We conducted duplicate data extraction, focusing on items that authors used to address RoB in the primary studies included in their reviews and the associated underlying domains, and summarized criteria in descriptive tables. We identified 42 eligible systematic reviews that addressed 23 items relevant to RoB and grouped the items into 7 domains: appropriate administration of instrument; instrument choice; instrument-described health state presentation; choice of participants group; description, analysis, and presentation of methods and results; patient understanding; and subgroup analysis. The items and domains identified provide insight into issues of RoB in patients' values and preference studies and establish the basis for an instrument to assess RoB in such studies.

2016-01-01

Rhabdomyolysis syndrome refers to a variety of factors that affect the striated muscle cell membrane, the membrane channels and its energy supply. Most cases of rhabdomyolysis are due to direct trauma. However, infection, toxins, drugs, muscle ischemia, electrolyte imbalance, metabolic diseases, genetic diseases and abnormal body temperature can also lead to rhabdomyolysis. Epilepsy is one of the most common chronic neurological diseases. The primary long-term treatment is antiepileptic drugs (AEDs), which may cause rhabdomyolysis. This article summarizes the characteristics, treatment methods and prognosis of patients with rhabdomyolysis that is induced by antiepileptic drugs. This review is based on PubMed, EMBASE and MEDLINE searches of the literature using the keywords "epilepsy", "antiepileptic drugs","status epilepticus","rhabdomyolysis", and "antiepileptic drugs and rhabdomyolysis syndrome" as well as extensive personal clinical experience with various antiepileptic drugs. Potential relationships between antiepileptic drugs and rhabdomyolysis are discussed. Worldwide, there are approximately 50 million epilepsy patients, most of whom are treated with drugs. Reports have indicated that the majority of antiepileptic drugs on the market can cause rhabdomyolysis. Although rhabdomyolysis induced by antiepileptic drugs is a rare condition with a low incidence, this condition has serious consequences and merits attention from clinicians.

2015-01-01

Introduction. Deficiencies in teamwork skills have been shown to contribute to the occurrence of adverse events during surgery. Consequently, several teamwork assessment tools have been developed to evaluate trainee nontechnical performance. This paper aims to provide an overview of these instruments and review the validity of each tool. Furthermore, the present paper aims to review the deficiencies surrounding training and propose several recommendations to address these issues. Methods. A systematic literature search was conducted to identify teamwork assessment tools using MEDLINE (1946 to August 2015), EMBASE (1974 to August 2015), and PsycINFO (1806 to August 2015) databases. Results. Eight assessment tools which encompass aspects of teamwork were identified. The Nontechnical Skills for Surgeons (NOTSS) assessment was found to possess the highest level of validity from a variety of sources; reliability and acceptability have also been established for this tool. Conclusions. Deficits in current surgical training pathways have prompted several recommendations to meet the evolving requirements of surgeons. Recommendations from the current paper include integration of teamwork training and assessment into medical school curricula, standardised formal training of assessors to ensure accurate evaluation of nontechnical skill acquisition, and integration of concurrent technical and nontechnical skills training throughout training.

Colic in infants causes one in six families (17%) with children to consult a health professional. One systematic review of 15 community-based studies found a wide variation in prevalence, which depended on study design and method of recording. We conducted a systematic review and aimed to answer the following clinical question: What are the effects of treatments for colic in infants? We searched: Medline, Embase, The Cochrane Library, and other important databases up to September 2009 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). We found 27 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. In this systematic review we present information relating to the effectiveness and safety of the following interventions: advice to increase carrying, advice to reduce stimulation, casein hydrolysate milk, cranial osteopathy, crib vibrator device, focused counselling, gripe water, infant massage, low-lactose milk, simethicone, soya-based infant feeds, spinal manipulation, and whey hydrolysate milk.

AIM: To present evidence and formulate recommendations for sedation in pediatric gastrointestinal (GI) endoscopy by non-anesthesiologists. METHODS: The databases MEDLINE, Cochrane and EMBASE were searched for the following keywords “endoscopy, GI”, “endoscopy, digestive system” AND “sedation”, “conscious sedation”, “moderate sedation”, “deep sedation” and “hypnotics and sedatives” for publications in English restricted to the pediatric age. We searched additional information published between January 2011 and January 2014. Searches for (upper) GI endoscopy sedation in pediatrics and sedation guidelines by non-anesthesiologists for the adult population were performed. RESULTS: From the available studies three sedation protocols are highlighted. Propofol, which seems to offer the best balance between efficacy and safety is rarely used by non-anesthesiologists mainly because of legal restrictions. Ketamine and a combination of a benzodiazepine and an opioid are more frequently used. Data regarding other sedatives, anesthetics and adjuvant medications used for pediatric GI endoscopy are also presented. CONCLUSION: General anesthesia by a multidisciplinary team led by an anesthesiologist is preferred. The creation of sedation teams led by non-anesthesiologists and a careful selection of anesthetic drugs may offer an alternative, but should be in line with national legislation and institutional regulations.

Microstructural abnormalities in white matter (WM) are often reported in Alzheimer's disease (AD) and may reflect primary or secondary circuitry degeneration (i.e., due to cortical atrophy). The interpretation of diffusion tensor imaging (DTI) eigenvectors, known as multiple indices, may provide new insights into the main pathological models supporting primary or secondary patterns of WM disruption in AD, the retrogenesis, and Wallerian degeneration models, respectively. The aim of this review is to analyze the current literature on the contribution of DTI multiple indices to the understanding of AD neuropathology, taking the retrogenesis model as a reference for discussion. A systematic review using MEDLINE, EMBASE, and PUBMED was performed. Evidence suggests that AD evolves through distinct patterns of WM disruption, in which retrogenesis or, alternatively, the Wallerian degeneration may prevail. Distinct patterns of WM atrophy may be influenced by complex interactions which comprise disease status and progression, fiber localization, concurrent risk factors (i.e., vascular disease, gender), and cognitive reserve. The use of DTI multiple indices in addition to other standard multimodal methods in dementia research may help to determine the contribution of retrogenesis hypothesis to the understanding of neuropathological hallmarks that lead to AD.

Due to the diverse and ever-changing nature of the healthcare industry, teaching pedagogies such as peer-assisted learning (PAL) are being implemented to align with external competency standards. A scoping review was conducted in order to map the breadth of literature available on PAL and its impact on student performance. This review used Arksey and O'Malley's six stage scoping methodology. The databases searched included: Cinahl, Ovid Medline, Proquest and Embase as well as grey literature sites and dissertations. 22 articles were included in this review, 10 of which were mixed methods randomised controlled trials, one retrospective study, four controlled trials, two randomised cross over controlled trial, three prospective randomised controlled trials, one thesis and one comparative research design. Analysis of the included articles identified three major themes outlining student performance. Student teachers themselves showed the most significant improvement in objective outcomes. The predominant healthcare field addressed were medical students with very few studies being completed on other professions. The search indicated an overall positive response to PAL with the measurable outcome of student tutors being of most significance. Further research is required to determine the relevance for the wider healthcare community. Copyright © 2016 Elsevier Ltd. All rights reserved.

ABSTRACT Objectives To review the current understanding of the biomarkers and enzymes associated with different forms peri-implant diseases and how their level changes influence the pathogenesis of the inflammatory diseases around dental implants. Material and Methods An electronic search in two different databases was performed including MEDLINE (PubMed) and EMBASE between 1996 to 2016. Human studies analyse peri-implant crevicular fluid (PICF) biomarker and enzyme levels of implants having peri-implant mucositis and peri-implantitis published in English language, were evaluated. A systematic review was performed to assess which biomarkers and enzymes in PICF were used to identify the inflammatory conditions around dental implants. Results Fifty-one articles were identified of which 41 were further evaluated and included in the analysis. Due to significant heterogeneity between included studies, a meta-analysis could not be performed. Instead, a systematic descriptive review was performed. Conclusions Biomarkers and enzymes in peri-implant crevicular fluid have shown promising results in differentiating from peri-implant disease condition to health. However, due to inconsistent results and acquiring much evidence from cross-sectional studies, additional evidence supported by randomized-controlled trials is needed to validate the links reported.

2015-01-01

Background The use of telemedicine has grown across several medical fields, due to the increasing number of “e-patients”. Objective This narrative review gives an overview of the growing use of telemedicine in different medical specialties, showing how its use can improve medical care. Methods A PubMed/Medline, Embase, Web of Science, and Scopus search was performed using the following keywords: telemedicine, teleconsultation, telehealth, e-health, and e-medicine. Selected papers from 1996 to 2014 were chosen on the basis of their content (quality and novelty). Results Telemedicine has already been applied to different areas of medical practice, and it is as effective as face-to-face medical care, at least for the diagnosis and treatment of some pathological conditions. Conclusion Telemedicine is time- and cost-effective for both patients and health care professionals, encouraging its use on a larger scale. Telemedicine provides specialist medical care to patients who have poor access to hospitals, and ensures continuity of care and optimal use of available health resources. The use of telemedicine opens new perspectives for patients seeking a medical second opinion for their pathology, since they can have remote access to medical resources that would otherwise require enormous costs and time.

2017-01-01

Diagnosis of peripheral oral exophytic lesions might be quite challenging. This review article aimed to introduce a decision tree for oral exophytic lesions according to their clinical features. General search engines and specialized databases including PubMed, PubMed Central, Medline Plus, EBSCO, Science Direct, Scopus, Embase, and authenticated textbooks were used to find relevant topics by means of keywords such as “oral soft tissue lesion,” “oral tumor like lesion,” “oral mucosal enlargement,” and “oral exophytic lesion.” Related English-language articles published since 1988 to 2016 in both medical and dental journals were appraised. Upon compilation of data, peripheral oral exophytic lesions were categorized into two major groups according to their surface texture: smooth (mesenchymal or nonsquamous epithelium-originated) and rough (squamous epithelium-originated). Lesions with smooth surface were also categorized into three subgroups according to their general frequency: reactive hyperplastic lesions/inflammatory hyperplasia, salivary gland lesions (nonneoplastic and neoplastic), and mesenchymal lesions (benign and malignant neoplasms). In addition, lesions with rough surface were summarized in six more common lesions. In total, 29 entities were organized in the form of a decision tree in order to help clinicians establish a logical diagnosis by a stepwise progression method. PMID:28757870

The skin prick test – European standards

PubMed Central

2013-01-01

Skin prick testing is an essential test procedure to confirm sensitization in IgE-mediated allergic disease in subjects with rhinoconjunctivitis, asthma, urticaria, anapylaxis, atopic eczema and food and drug allergy. This manuscript reviews the available evidence including Medline and Embase searches, abstracts of international allergy meetings and position papers from the world allergy literature. The recommended method of prick testing includes the appropriate use of specific allergen extracts, positive and negative controls, interpretation of the tests after 15 – 20 minutes of application, with a positive result defined as a wheal ≥3 mm diameter. A standard prick test panel for Europe for inhalants is proposed and includes hazel (Corylus avellana), alder (Alnus incana), birch (Betula alba), plane (Platanus vulgaris), cypress (Cupressus sempervirens), grass mix (Poa pratensis, Dactilis glomerata, Lolium perenne, Phleum pratense, Festuca pratensis, Helictotrichon pretense), Olive (Olea europaea), mugwort (Artemisia vulgaris), ragweed (Ambrosia artemisiifolia), Alternaria alternata (tenuis), Cladosporium herbarum, Aspergillus fumigatus, Parietaria, cat, dog, Dermatophagoides pteronyssinus, Dermatophagoides farinae, and cockroach (Blatella germanica). Standardization of the skin test procedures and standard panels for different geographic locations are encouraged worldwide to permit better comparisons for diagnostic, clinical and research purposes.

2017-01-01

Objectives To critically appraise the efficacy and safety of Kangfuxinye enema combined with mesalamine for the ulcerative colitis (UC) patients and in addition to grade the quality of evidence by using the GRADE (grading of recommendations, assessment, development, and evaluation) approach. Methods A literature search was performed in the Cochrane Library, MEDLINE, EMBASE, CBM, CNKI, VIP, and WanFang Databases. The search restrictions were patients with UC and RCTs. Studies including other treatments except Kangfuxinye with mesalamine were excluded. Results Nineteen studies met the inclusion criteria. We found significant benefits of Kangfuxinye combined with mesalamine against mesalamine alone in improving response rate as well as reducing the recurrence rate and inflammation rate; meanwhile, the increase of the adverse events rate was not observed. Furthermore, the symptoms remission rate and the cure time were insignificant statistically. Additionally, GRADE results indicated that the quality of evidence regarding the above 6 outcomes was rated from very low to moderate quality. Conclusions Although Kangfuxinye enema seems effective and safe for treating UC patients in this systematic review, Kangfuxinye enema combined with mesalamine was weakly recommended due to very low to moderate quality of available evidence by the GRADE approach.

AIM: To assess the safety of bismuth used in Helicobacter pylori (H pylori) eradication therapy regimens. METHODS: We conducted a systematic review and meta-analysis. MEDLINE and EMBASE were searched (up to October 2007) to identify randomised controlled trials comparing bismuth with placebo or no treatment, or bismuth salts in combination with antibiotics as part of eradication therapy with the same dose and duration of antibiotics alone or, in combination, with acid suppression. Total numbers of adverse events were recorded. Data were pooled and expressed as relative risks with 95% confidence intervals (CI). RESULTS: We identified 35 randomised controlled trials containing 4763 patients. There were no serious adverse events occurring with bismuth therapy. There was no statistically significant difference detected in total adverse events with bismuth [relative risk (RR) = 1.01; 95% CI: 0.87-1.16], specific individual adverse events, with the exception of dark stools (RR = 5.06; 95% CI: 1.59-16.12), or adverse events leading to withdrawal of therapy (RR = 0.86; 95% CI: 0.54-1.37). CONCLUSION: Bismuth for the treatment of H pylori is safe and well-tolerated. The only adverse event occurring significantly more commonly was dark stools. PMID:19109870

Objective To assess the level of equivocation among level 1 evidence in ulcerative colitis and Crohn’s disease and determine whether any predisposing factors are present. Method MEDLINE, Embase, CINHAL and Cochrane were searched from 2006 to 2017. Papers were scored using AMSTAR and categorised into surgical (S), medical (M) or medical and surgical (MS) groups. The ability of each paper to make a recommendation and conclusiveness in doing so was recorded. Results 278 papers were assessed. 82% (n=227) could make a recommendation, 18% (n=51) could not. There was a significant difference in ability to provide a recommendation between S and M (P=0.003) but not MS and M (P=0.022) nor S and MS (P=0.79). Where a recommendation was made, S papers were more likely to be tempered than M papers (P=0.014) but not MS papers (P=0.987). Conclusions Surgical meta-evidence within the inflammatory bowel disease domain is more than twice as likely as medical meta-evidence to be unable to provide a recommendation for clinical practice. Where a recommendation was made, surgical reviews were twice as likely to temper their conclusion. PMID:29259063

Chinese herbal medicine and depression: the research evidence.

PubMed

Butler, Lee; Pilkington, Karen

2013-01-01

Background. Alternative approaches for managing depression are often sought and herbal mixtures are widely used in China. The aim of this paper was to provide an overall picture of the current evidence by analysing published systematic reviews and presenting a supplementary systematic review of trials in Western databases. Methods. Searches were conducted using AMED, Cochrane Library, EMBASE, MEDLINE/PubMed, PsycINFO, and trial registers. Results were screened and selected trials were evaluated by two reviewers working independently. Systematic reviews were identified and assessed using key criteria. Results. Five systematic reviews were located addressing the Chinese literature, adjunctive use of Chinese herbs, and the formulae Chaihu-Shugan-San, Xiao Yao San, and Free and Easy Wanderer Plus. The supplementary review located 8 trials, 3 of which were not included in previous reviews. Positive results were reported: no significant differences from medication, greater effect than medication or placebo, reduced adverse event rates when combined or compared with antidepressants. However, limitations in methodology and reporting were revealed. Conclusions. Despite promising results, particularly for Xiao Yao San and its modifications, the effectiveness of Chinese herbal medicine in depression could not be fully substantiated based on current evidence. Further well-designed, well-reported trials that reflect practice may be worth pursuing.

2008-01-01

Background In acromegaly, expert surgery is curative in only about 60% of patients. Postoperative radiation therapy is associated with a high incidence of hypopituitarism and its effect on growth hormone (GH) production is slow, so that adjuvant medical treatment becomes of importance in the management of many patients. Objective To delineate the role of lanreotide in the treatment of acromegaly. Methods Search of Medline, Embase, and Web of Science databases for clinical studies of lanreotide in acromegaly. Results Treatment with lanreotide slow release and lanreotide Autogel® normalized GH and insulin-like growth factor-I (IGF-I) concentrations in about 50% of patients. The efficacy of 120 mg lanreotide Autogel® on GH and IGF-I levels was comparable with that of 20 mg octreotide LAR. There were no differences in improvement of cardiac function, decrease in pancreatic β-cell function, or occurrence of side effects, including cholelithiasis, between octreotide LAR and lanreotide Autogel®. When postoperative treatment with somatostatin analogs does not result in normalization of serum IGF-I and GH levels after noncurative surgery, pegvisomant alone or in combination with somatostatin analogs can control these levels in a substantial number of patients.

Recent epidemiologic studies have suggested that appendectomy could be a risk factor for primary sclerosing cholangitis (PSC) although the results were inconsistent. This systematic review and meta-analysis was conducted to summarize all available evidence. A comprehensive literature review was conducted using MEDLINE and EMBASE database through January 2018 to identify all studies that reported the risk of PSC among individuals who had appendectomy versus those with no history of appendectomy. Effect estimates from each study were extracted and combined together using the random-effect, generic inverse variance method of DerSimonian and Laird. A total of 6 case-control studies with 2432 participants met the eligibility criteria and were included in the meta-analysis. The risk of PSC in individuals who had appendectomy was significantly higher than those with no history of appendectomy with the pooled odds ratio of 1.37 (95% CI: 1.15-1.63). The statistical heterogeneity was insignificant with an I2 of 0%. A significantly increased risk of PSC among individuals who had a history of appendectomy was found in this study.

Purpose The purpose of the present systematic review was to develop a practice guideline to inform health care providers about screening, assessment, and effective management of cancer-related fatigue (crf) in adults. Methods The internationally endorsed adapte methodology was used to develop a practice guideline for pan-Canadian use. A systematic search of the literature identified a broad range of evidence: clinical practice guidelines, systematic reviews, and other guidance documents on the screening, assessment, and management of crf. The search included medline, embase, cinahl, the Cochrane Library, and other guideline and data sources to December 2009. Results Two clinical practice guidelines were identified for adaptation. Seven guidance documents and four systematic reviews also provided supplementary evidence to inform guideline recommendations. Health professionals across Canada provided expert feedback on the adapted recommendations in the practice guideline and algorithm through a participatory external review process. Conclusions Practice guidelines can facilitate the adoption of evidence-based assessment and interventions for adult cancer patients experiencing fatigue. Development of an algorithm to guide decision-making in practice may also foster the uptake of a guideline into routine care. PMID:23737693

[Purpose] To provide data for systematic intervention plans in occupational therapy practice by objectivity showing the value of mirror therapy interventions in children with cerebral palsy. [Subjects and Methods] Medline and EMBASE databases were searched for the key words “cerebral palsy,” “mirror movement,” “mirror therapy,” and “mirror visual feedback.” Nine studies that met the inclusion and exclusion criteria were identified. The qualitatively determined level of evidence, period of research, comparisons and interventions, tools used to measure the intervention, and the effects were analyzed. [Results] According to the results analyzed, one (1/9, 11.1%) study showed the same result as the control group, one (1/9, 11.1%) showed a negative effect, and seven (7/9, 77.8%) showed positive effects of mirror-mediated therapy, with meaningful improvement in function, such as hand strength, movement speed, muscle activity, and accuracy of hand matching. [Conclusion] Through this study, the value of mirror-mediated therapeutic interventions in occupational therapy practice targeting cerebral palsy was confirmed. It is expected that this result will be useful in establishing mirror therapy as an interventional program. PMID:27942154

Background To date, there is no compilation of evidence-based information associating bacteremia and periodontal procedures. This systematic review aims to assess magnitude, duration, prevalence and nature of bacteremia caused by periodontal procedures. Study Design Systematic Review Types of Studies Reviewed MEDLINE, EMBASE and LILACS databases were searched in duplicate through August, 2013 without language restriction. Observational studies were included if blood samples were collected before, during or after periodontal procedures of patients with periodontitis. The methodological quality was assessed in duplicate using the modified Newcastle-Ottawa scale (NOS). Results Search strategy identified 509 potentially eligible articles and nine were included. Only four studies demonstrated high methodological quality, whereas five were of medium or low methodological quality. The study characteristics were considered too heterogeneous to conduct a meta-analysis. Among 219 analyzed patients, 106 (49.4%) had positive bacteremia. More frequent bacteria were S. viridans, A. actinomycetemcomitans P. gingivalis, M. micros and species Streptococcus and Actinomyces, although identification methods of microbiologic assays were different among studies. Clinical Implications Although half of the patients presented positive bacteremia after periodontal procedures, accurate results regarding the magnitude, duration and nature of bacteremia could not be confidentially assessed.

Background. Policymakers need estimates of the impact of tobacco control (TC) policies to set priorities and targets for reducing tobacco use. We systematically reviewed the independent effects of TC policies on smoking behavior. Methods. We searched MEDLINE (through January 2012) and EMBASE and other databases through February 2009, looking for studies published after 1989 in any language that assessed the effects of each TC intervention on smoking prevalence, initiation, cessation, or price participation elasticity. Paired reviewers extracted data from studies that isolated the impact of a single TC intervention. Findings. We included 84 studies. The strength of evidence quantifying the independent effect on smoking prevalence was high for increasing tobacco prices and moderate for smoking bans in public places and antitobacco mass media campaigns. Limited direct evidence was available to quantify the effects of health warning labels and bans on advertising and sponsorship. Studies were too heterogeneous to pool effect estimates. Interpretations. We found evidence of an independent effect for several TC policies on smoking prevalence. However, we could not derive precise estimates of the effects across different settings because of variability in the characteristics of the intervention, level of policy enforcement, and underlying tobacco control environment.

Treatment of obstructive sleep apnea (OSA) using methods for increasing upper airway muscle tonus has been controversial and poorly reported. Thus, a review of the evidence is needed to evaluate the effectiveness of these methods. The design used was a systematic review of randomized controlled trials. Data sources are from the Cochrane Library, Medline, Embase and Scielo, registries of ongoing trials, theses indexed at Biblioteca Regional de Medicina/Pan-American Health Organization of the World Health Organization and the reference lists of all the trials retrieved. This was a review of randomized or quasi-randomized double-blind trials on OSA. Two reviewers independently applied eligibility criteria. One reviewer assessed study quality and extracted data, and these processes were checked by a second reviewer. The primary outcome was a decrease in the apnea/hypopnea index (AHI) of below five episodes per hour. Other outcomes were subjective sleep quality, sleep quality measured by night polysomnography, quality of life measured subjectively and adverse events associated with the treatments. Three eligible trials were included. Two studies showed improvements through the objective and subjective analyses, and one study showed improvement of snoring, but not of AHI while the subjective analyses showed no improvement. The adverse events were reported and they were not significant. There is no accepted scientific evidence that methods aiming to increase muscle tonus of the stomatognathic system are effective in reducing AHI to below five events per hour. Well-designed randomized controlled trials are needed to assess the efficacy of such methods.

Measurement properties of existing clinical assessment methods evaluating scapular positioning and function. A systematic review.

2014-10-01

The aims were to compile a schematic overview of clinical scapular assessment methods and critically appraise the methodological quality of the involved studies. A systematic, computer-assisted literature search using Medline, CINAHL, SportDiscus and EMBASE was performed from inception to October 2013. Reference lists in articles were also screened for publications. From 50 articles, 54 method names were identified and categorized into three groups: (1) Static positioning assessment (n = 19); (2) Semi-dynamic (n = 13); and (3) Dynamic functional assessment (n = 22). Fifteen studies were excluded for evaluation due to no/few clinimetric results, leaving 35 studies for evaluation. Graded according to the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN checklist), the methodological quality in the reliability and validity domains was "fair" (57%) to "poor" (43%), with only one study rated as "good". The reliability domain was most often investigated. Few of the assessment methods in the included studies that had "fair" or "good" measurement property ratings demonstrated acceptable results for both reliability and validity. We found a substantially larger number of clinical scapular assessment methods than previously reported. Using the COSMIN checklist the methodological quality of the included measurement properties in the reliability and validity domains were in general "fair" to "poor". None were examined for all three domains: (1) reliability; (2) validity; and (3) responsiveness. Observational evaluation systems and assessment of scapular upward rotation seem suitably evidence-based for clinical use. Future studies should test and improve the clinimetric properties, and especially diagnostic accuracy and responsiveness, to increase utility for clinical practice.

Objective Costs for radiation therapy (rt) and the methods used to cost rt are highly diverse across the literature. To date, no study has compared various costing methods in detail. Our objective was to perform a thorough review of the radiation costing literature to identify sources of costs and methods used. Methods A systematic review of Ovid medline, Ovid oldmedline, embase, Ovid HealthStar, and EconLit from 2005 to 23 March 2015 used search terms such as “radiation,” “radiotherapy,” “neoplasm,” “cost,” “ cost analysis,” and “cost benefit analysis” to locate relevant articles. Original papers were reviewed for detailed costing methods. Cost sources and methods were extracted for papers investigating rt modalities, including three-dimensional conformal rt (3D-crt), intensity-modulated rt (imrt), stereotactic body rt (sbrt), and brachytherapy (bt). All costs were translated into 2014 U.S. dollars. Results Most of the studies (91%) reported in the 33 articles retrieved provided rt costs from the health system perspective. The cost of rt ranged from US$2,687.87 to US$111,900.60 per treatment for imrt, followed by US$5,583.28 to US$90,055 for 3D-crt, US$10,544.22 to US$78,667.40 for bt, and US$6,520.58 to US$19,602.68 for sbrt. Cost drivers were professional or personnel costs and the cost of rt treatment. Most studies did not address the cost of rt equipment (85%) and institutional or facility costs (66%). Conclusions Costing methods and sources were widely variable across studies, highlighting the need for consistency in the reporting of rt costs. More work to promote comparability and consistency across studies is needed. PMID:27536189

A thorough review of the literature is the basis of all research and evidence-based practice. A gold-standard efficient and exhaustive search strategy is needed to ensure all relevant citations have been captured and that the search performed is reproducible. The PubMed database comprises both the MEDLINE and non-MEDLINE databases. MEDLINE-based search strategies are robust but capture only 89% of the total available citations in PubMed. The remaining 11% include the most recent and possibly relevant citations but are only searchable through less efficient techniques. An effective search strategy must employ both the MEDLINE and the non-MEDLINE portion of PubMed to ensure all studies have been identified. The robust MEDLINE search strategies are used for the MEDLINE portion of the search. Usage of the less robust strategies is then efficiently confined to search only the remaining 11% of PubMed citations that have not been indexed for MEDLINE. The current article offers step-by-step instructions for building such a search exploring methods for the discovery of medical subject heading (MeSH) terms to search MEDLINE, text-based methods for exploring the non-MEDLINE database, information on the limitations of convenience algorithms such as the “related citations feature,” the strengths and pitfalls associated with commonly used filters, the proper usage of Boolean operators to organize a master search strategy, and instructions for automating that search through “MyNCBI” to receive search query updates by email as new citations become available.

OBJECTIVES The objectives of this report are to determine the following: (1) the effectiveness of the toilet training methods, (2) which factors modify the effectiveness of toilet training, (3) if the toilet training methods are risk factor for adverse outcomes, and (4) the optimal toilet training method for achieving bowel and bladder control among patients with special needs. DATA SOURCES MEDLINE, Ovid MEDLINE In-Process & Other Non-Indexed Citations, Ovid OLDMEDLINE, Cochrane Central Register of Controlled Trials, EMBASE, CINAHL, PsycINFO, ERIC, EBM Reviews, HealthSTAR, AMED, Web of Science, Biological Abstracts, Sociological Abstracts, OCLC ProceedingsFirst, OCLC PapersFirst, Dissertation Abstracts, Index to Theses, National Research Register's Projects Database, and trials registers. REVIEW METHODS Two reviewers assessed the studies for inclusion. Studies were included if they met the following criteria: STUDY DESIGN RCT, CCT, prospective or retrospective cohort, case-control, cross-sectional or case-series; POPULATION infants, toddlers, or children with or without co-morbidities, neuromuscular, cognitive, or behavioral handicaps disabilities; INTERVENTION at least one toilet training method; and OUTCOME bladder and/or bowel control, successes, failures, adverse outcomes. Methodological quality was assessed independently by two reviewers. Data were extracted by one reviewer and a second checked for accuracy and completeness. Due to substantial heterogeneity, meta-analysis was not possible. RESULTS Twenty-six observational studies and eight controlled trials were included. Approximately half of the studies examined healthy children while the remaining studies assessed toilet training of mentally or physically handicapped children. For healthy children, the Azrin and Foxx method performed better than the Spock method, while child-oriented combined with negative term avoidance proved better than without. For mentally handicapped children, individual training was superior to group methods; relaxation techniques proved more efficacious than standard methods; operant conditioning was better than conventional treatment, and the Azrin and Foxx and a behavior modification method fared better than no training. The child-oriented approach was not assessed among mentally handicapped children. For children with Hirschsprung's disease or anal atresia, a multi-disciplinary behavior treatment was more efficacious than no treatment. CONCLUSIONS Both the Azrin and Foxx method and the child-oriented approach resulted in quick, successful toilet training, but there was limited information about the sustainability of the training. The two methods were not directly compared, thus it is difficult to draw definitive conclusions regarding the superiority of one method over the other. In general, both programs may be used to teach toilet training to healthy children. The Azrin and Foxx method and operant conditioning methods were consistently effective for toilet training mentally handicapped children. Programs that were adapted to physically handicapped children also resulted in successful toilet training. A lack of data precluded conclusions regarding the development of adverse outcomes.

Effective leadership of healthcare professionals is critical for strengthening quality and integration of care. This study aimed to assess whether there exist an association between different leadership styles and healthcare quality measures. The search was performed in the Medline (National Library of Medicine, PubMed interface) and EMBASE databases for the time period 2004-2015. The research question that guided this review was posed as: "Is there any relationship between leadership style in healthcare settings and quality of care?" Eighteen articles were found relevant to our research question. Leadership styles were found to be strongly correlated with quality care and associated measures. Leadership was considered a core element for a well-coordinated and integrated provision of care, both from the patients and healthcare professionals.

2018-01-01

The surgical treatment of cervical radiculopathy has centered around anterior cervical discectomy and fusion (ACDF). Alternatively, the posterior cervical laminoforaminotomy/microdiscectomy (PCF/PCM), which results in comparable outcomes and is more cost-effective, has been underutilized. Here, we compared the direct/indirect costs, reoperation rates, and outcome for ACDF and PCF vs. PCM using PubMed, Medline, and Embase databases. There were no significant differences between the re-operative rates of PCF/PCM (2% to 9.8%) versus ACDF (2% to 8%). Direct costs of ACDF were also significantly higher; the 1-year cost-utility analysis demonstrated that ACDF had $131,951/QALY while PCM had $79,856/QALY. PCF/PCM for radiculopathy are safe and more cost-effective vs. ACDF, and have similar clinical outcomes.

Are probiotics effective in preventing urinary tract infection?

PubMed

Canales, Juan; Rada, Gabriel

2018-04-04

Urinary tract infection is the most common bacterial infection and recurrences are common. Probiotics have been proposed as an alternative to decrease this risk. However, it is not clear if they are really effective. To answer this question we used Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. We identified six systematic reviews including nine studies overall, of which seven were randomized trials. We concluded it is not clear whether probiotics decrease the risk of symptomatic urinary tract infection, because the certainty of the evidence is very low.

Systemic corticosteroids constitute standard treatment in children with acute obstructive laryngitis (croup). However, there is some uncertainty in relation with the magnitude of the benefits and risks associated with their use. To answer this question, we used Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We identified six systematic reviews including 25 randomized trials relevant for the question of interest. We extracted data from the systematic reviews, reananalysed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. We concluded the use of systemic corticosteroids increases the number of patients with clinical improvement at 12 hours and reduces the risk of readmission.

Abernethy, Liz; Bleakley, Chris

2007-01-01

This systematic review set out to identify randomised controlled trials and controlled intervention studies that evaluated the effectiveness of preventive strategies in adolescent sport and to draw conclusions on the strength of the evidence. A literature search in seven databases (Medline, SportDiscus, EMBASE, CINAHL, PEDro, Cochrane Review and DARE) was carried out using four keywords: adolescent, sport, injury and prevention (expanded to capture any relevant literature). Assessment of 154 papers found 12 studies eligible for inclusion. It can be concluded that injury prevention strategies that focus on preseason conditioning, functional training, education, balance and sport‐specific skills, which should be continued throughout the sporting season, are effective. The evidence for the effectiveness of protective equipment in injury prevention is inconclusive and requires further assessment. PMID:17496070

2016-01-01

Patient views about their treatment for insomnia often dictate outcome. This review explores the literature relating to the patients' global perceptions toward treatment for insomnia. A strategic literature search was conducted using five databases (PubMed, CINAHL, Medline, PsycINFO, and Embase). The 57 research articles included for this review were mapped out chronologically across three key stages of treatment-seeking (pretreatment appraisal, actual treatment experiences, and posttreatment evaluation). Patient perceptions played an important role across these three key stages and influenced subsequent health behaviors such as the initiation of help-seeking, treatment uptake, treatment adherence, and treatment adjustment. Patients' perceptions toward treatment were heavily grounded by their psychosocial contexts. Clinical implications and future directions for including patient-centered metrics in mainstream practice and research are discussed.

Thimerosal-Containing Vaccines and Autism: A Review of Recent Epidemiologic Studies

Hurley, Anne M.; Tadrous, Mina; Miller, Elizabeth S.

2010-01-01

Although epidemiologic evidence has not supported the hypothesis of a causal relationship between thimerosal-containing vaccines and autism, concerns continue about pediatric exposure to mercury through vaccine administration. A statement issued by the American Academy of Pediatrics and the US Public Health Service in 1999 prompted the removal of thimerosal from many vaccines. In 2004, the Immunization Safety Review Committee of the Institute of Medicine rejected the hypothesis of a causal relationship between thimerosal-containing vaccines and autism. In a search of MEDLINE and EMBASE, we identified articles that address the potential association between thimerosal and neurodevelopmental disorders, specifically autism. In this article, we review recent pharmacokinetic and epidemiologic studies published between 2003 and 2008 regarding the proposed link between thimerosal and autism. PMID:22477809

2015-01-01

We examined the impact of regulatory action to reduce levels of artificial trans–fatty acids (TFAs) in food. We searched Medline, Embase, ISI Web of Knowledge, and EconLit (January 1980 to December 2012) for studies related to government regulation of food- or diet-related health behaviors from which we extracted the subsample of legislative initiatives to reduce artificial TFAs in food. We screened 38 162 articles and identified 14 studies that examined artificial TFA controls limiting permitted levels or mandating labeling. These measures achieved good compliance, with evidence of appropriate reformulation. Regulations grounded on maximum limits and mandated labeling can lead to reductions in actual and reported TFAs in food and appear to encourage food producers to reformulate their products.

2009-01-01

The purpose of this paper is to discuss critically the antibacterial efficacy of intracanal medicaments on bacterial biofilm. Longitudinal studies were evaluated by a systematic review of English-language articles retrieved from electronic biomedical journal databases (MEDLINE, EMBASE, CENTRAL) and handsearching records, using different matches of keywords for root canal biofilm, between 1966 and August 1st, 2007. The selected articles were identified from titles, abstracts and full-text articles by two independent reviewers, considering the tabulated inclusion and exclusion criteria. Disagreements were resolved by consensus. The search retrieved 91 related articles, of which 8.8% referred to in vivo studies demonstrating the lack of efficacy of endodontic therapy on bacterial biofilm. Intracanal medicaments were found to have a limited action against bacterial biofilm. PMID:19148398

This seventh best‐practice review examines four series of common primary care questions in laboratory medicine: (1) blood count abnormalities 2; (2) cardiac troponins; (3) high‐density lipoprotein cholesterol; and (4) viral diseases 2. The review is presented in a question–answer format, with authorship attributed for each question series. The recommendations are a précis of guidance found using a standardised literature search of national and international guidance notes, consensus statements, health policy documents and evidence‐based medicine reviews, supplemented by Medline Embase searches to identify relevant primary research documents. The recommendations are not standards, but form a guide to be set in the clinical context. Most are consensus based rather than evidence based. They will be updated periodically to take account of new information. PMID:17046843

Disposable surgical face masks for preventing surgical wound infection in clean surgery.

PubMed

Lipp, Allyson; Edwards, Peggy

2014-02-17

Surgical face masks were originally developed to contain and filter droplets containing microorganisms expelled from the mouth and nasopharynx of healthcare workers during surgery, thereby providing protection for the patient. However, there are several ways in which surgical face masks could potentially contribute to contamination of the surgical wound, e.g. by incorrect wear or by leaking air from the side of the mask due to poor string tension. To determine whether disposable surgical face masks worn by the surgical team during clean surgery prevent postoperative surgical wound infection. We searched The Cochrane Wounds Group Specialised Register on 23 October 2013; The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library); Ovid MEDLINE; Ovid MEDLINE (In-Process & Other Non-Indexed Citations); Ovid EMBASE; and EBSCO CINAHL. Randomised controlled trials (RCTs) and quasi-randomised controlled trials comparing the use of disposable surgical masks with the use of no mask. Two review authors extracted data independently. Three trials were included, involving a total of 2113 participants. There was no statistically significant difference in infection rates between the masked and unmasked group in any of the trials. From the limited results it is unclear whether the wearing of surgical face masks by members of the surgical team has any impact on surgical wound infection rates for patients undergoing clean surgery.

In the last years there has been a significant increase in reported cases of pertussis in developed countries, in spite of high rates of childhood immunization. Health institutions have recommended different vaccination strategies to reduce child morbidity and mortality: vaccination of adolescents and adults, pregnant women, people in contact with the newborn (cocoon strategy) and health care workers. The aim of this paper is to review the scientific evidence supporting these recommendations. Systematic review on the effectiveness and cost-effectiveness of the above strategies for the reduction of morbidity and mortality from pertussis in infants under 12 months. The electronic databases Medline, PreMedline, Embase, CRD, Cochrane Central, and Trip Database were consulted from 1990 to October 2012. The evidence was assessed using the GRADE system. There were eight studies on the efficacy or safety of the strategies analyzed, and 18 economic evaluations. Direct evidence on the efficacy of these strategies is scarce. Economic evaluations suggest that vaccination of adolescents and adults would be cost-effective, although there is major uncertainty over the parameters used. From the perspective of health technology assessment, there is insufficient evidence to recommend the vaccination strategies evaluated. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

The objectives of this report are to determine the following: (1) the effectiveness of the toilet training methods, (2) which factors modify the effectiveness of toilet training, (3) if the toilet training methods are risk factor for adverse outcomes, and (4) the optimal toilet training method for achieving bowel and bladder control among patients with special needs. MEDLINE, Ovid MEDLINE In-Process & Other Non-Indexed Citations, Ovid OLDMEDLINE, Cochrane Central Register of Controlled Trials, EMBASE, CINAHL, PsycINFO, ERIC, EBM Reviews, HealthSTAR, AMED, Web of Science, Biological Abstracts, Sociological Abstracts, OCLC ProceedingsFirst, OCLC PapersFirst, Dissertation Abstracts, Index to Theses, National Research Register's Projects Database, and trials registers. Two reviewers assessed the studies for inclusion. Studies were included if they met the following criteria: RCT, CCT, prospective or retrospective cohort, case-control, cross-sectional or case-series; infants, toddlers, or children with or without co-morbidities, neuromuscular, cognitive, or behavioral handicaps disabilities; at least one toilet training method; and bladder and/or bowel control, successes, failures, adverse outcomes. Methodological quality was assessed independently by two reviewers. Data were extracted by one reviewer and a second checked for accuracy and completeness. Due to substantial heterogeneity, meta-analysis was not possible. Twenty-six observational studies and eight controlled trials were included. Approximately half of the studies examined healthy children while the remaining studies assessed toilet training of mentally or physically handicapped children. For healthy children, the Azrin and Foxx method performed better than the Spock method, while child-oriented combined with negative term avoidance proved better than without. For mentally handicapped children, individual training was superior to group methods; relaxation techniques proved more efficacious than standard methods; operant conditioning was better than conventional treatment, and the Azrin and Foxx and a behavior modification method fared better than no training. The child-oriented approach was not assessed among mentally handicapped children. For children with Hirschsprung's disease or anal atresia, a multi-disciplinary behavior treatment was more efficacious than no treatment. Both the Azrin and Foxx method and the child-oriented approach resulted in quick, successful toilet training, but there was limited information about the sustainability of the training. The two methods were not directly compared, thus it is difficult to draw definitive conclusions regarding the superiority of one method over the other. In general, both programs may be used to teach toilet training to healthy children. The Azrin and Foxx method and operant conditioning methods were consistently effective for toilet training mentally handicapped children. Programs that were adapted to physically handicapped children also resulted in successful toilet training. A lack of data precluded conclusions regarding the development of adverse outcomes.

Abstract Objective To assess the burden posed by foodborne diseases in Japan using methods developed by the World Health Organization’s Foodborne Disease Burden Epidemiology Reference Group (FERG). Methods Expert consultation and statistics on food poisoning during 2011 were used to identify three common causes of foodborne disease in Japan: Campylobacter and Salmonella species and enterohaemorrhagic Escherichia coli (EHEC). We conducted systematic reviews of English and Japanese literature on the complications caused by these pathogens, by searching Embase, the Japan medical society abstract database and Medline. We estimated the annual incidence of acute gastroenteritis from reported surveillance data, based on estimated probabilities that an affected person would visit a physician and have gastroenteritis confirmed. We then calculated disability-adjusted life-years (DALYs) lost in 2011, using the incidence estimates along with disability weights derived from published studies. Findings In 2011, foodborne disease caused by Campylobacter species, Salmonella species and EHEC led to an estimated loss of 6099, 3145 and 463 DALYs in Japan, respectively. These estimated burdens are based on the pyramid reconstruction method; are largely due to morbidity rather than mortality; and are much higher than those indicated by routine surveillance data. Conclusion Routine surveillance data may indicate foodborne disease burdens that are much lower than the true values. Most of the burden posed by foodborne disease in Japan comes from secondary complications. The tools developed by FERG appear useful in estimating disease burdens and setting priorities in the field of food safety. PMID:26478611

Background It is widely believed that females have longer telomeres than males, although results from studies have been contradictory. Methods We carried out a systematic review and meta-analyses to test the hypothesis that in humans, females have longer telomeres than males and that this association becomes stronger with increasing age. Searches were conducted in EMBASE and MEDLINE (by November 2009) and additional datasets were obtained from study investigators. Eligible observational studies measured telomeres for both females and males of any age, had a minimum sample size of 100 and included participants not part of a diseased group. We calculated summary estimates using random-effects meta-analyses. Heterogeneity between studies was investigated using sub-group analysis and meta-regression. Results Meta-analyses from 36 cohorts (36,230 participants) showed that on average females had longer telomeres than males (standardised difference in telomere length between females and males 0.090, 95% CI 0.015, 0.166; age-adjusted). There was little evidence that these associations varied by age group (p = 1.00) or cell type (p = 0.29). However, the size of this difference did vary by measurement methods, with only Southern blot but neither real-time PCR nor Flow-FISH showing a significant difference. This difference was not associated with random measurement error. Conclusions Telomere length is longer in females than males, although this difference was not universally found in studies that did not use Southern blot methods. Further research on explanations for the methodological differences is required. PMID:24365661

Problem-based learning is an educational method promoting clinical reasoning that has been implemented in many fields of health education. Questioning is a learning strategy often employed in problem-based learning sessions. To explore what is known about the influence of questioning on the promotion of clinical reasoning of students in health care education, specifically in the field of nursing and using the educational method of problem-based learning. A scoping review following Arksey and O'Malley's five stages was conducted. The CINAHL, EMBASE, ERIC, Medline, and PubMed databases were searched for articles published between the years of 2000 and 2017. Each article was summarized and analyzed using a data extraction sheet in relation to its purpose, population group, setting, methods, and results. A descriptive explication of the studies based on an inductive analysis of their findings to address the aim of the review was made. Nineteen studies were included in the analysis. The studies explored the influence of questioning on critical thinking rather than on clinical reasoning. The nature of the questions asked and the effect of higher-order questions on critical thinking were the most commonly occurring themes. Few studies addressed the use of questioning in problem-based learning. More empirical evidence is needed to gain a better understanding of the benefit of questioning in problem-based learning to promote students' clinical reasoning. Copyright © 2018 Elsevier Ltd.

MRI-based hip cartilage measures in osteoarthritic and non-osteoarthritic individuals: a systematic review

PubMed Central

Aguilar, Hector N; Battié, Michele C

2017-01-01

Osteoarthritis is a common hip joint disease, involving loss of articular cartilage. The prevalence and prognosis of hip osteoarthritis have been difficult to determine, with various clinical and radiological methods used to derive epidemiological estimates exhibiting significant heterogeneity. MRI-based methods directly visualise hip joint cartilage, and offer potential to more reliably define presence and severity of osteoarthritis, but have been underused. We performed a systematic review of MRI-based estimates of hip articular cartilage in the general population and in patients with established osteoarthritis, using MEDLINE, EMBASE and SCOPUS current to June 2016, with search terms such as ‘hip’, ‘femoral head’, ‘cartilage’, ‘volume’, ‘thickness’, ‘MRI’, etc. Ultimately, 11 studies were found appropriate for inclusion, but they were heterogeneous in osteoarthritis assessment methodology and composition. Overall, the studies consistently demonstrate the reliability and potential clinical utility of MRI-based estimates. However, no longitudinal data or reference values for hip cartilage thickness or volume have been published, limiting the ability of MRI to define or risk-stratify hip osteoarthritis. MRI-based techniques are available to quantify articular cartilage signal, volume, thickness and defects, which could establish the sequence and rate of articular cartilage changes at the hip that yield symptomatic osteoarthritis. However, prevalence and rates of progression of hip osteoarthritis have not been established in any MRI studies in the general population. Future investigations could fill this important knowledge gap using robust MRI methods in population-based cross-sectional and longitudinal studies. PMID:28405471

Aim of the study Irreversible electroporation is a new, non-thermal ablation technique in the treatment of parenchymal organ tumors which uses short high voltage pulses of electricity in order to induce apoptosis of targeted cells. In this paper the application of this method of treatment in locally advanced pancreatic cancer (LAPC) and liver cancer is analyzed. Material and methods Between 04.2014 and 09.2014 two patients with LAPC and one with colorectal liver metastasis (CRLM) were qualified for treatment with irreversible electroporation. Both patients remained under constant observation and control. PubMed/Medline, Embase and Google Scholar databases were searched and eight original reports on irreversible electroporation of pancreatic and liver tumors based on the biggest groups of patients were found. Results Two patients with LAPC and one with CRLM were qualified for ablation with irreversible electroporation. In all three patients a successful irreversible electroporation (IRE) procedure of the whole tumor was conducted. In the minimum seven-month follow-up 100% local control was achieved – without progression. In the literature review the local response to treatment ranged from 41% to 100%. The event-free survival rate in six-month observation was 94%. Conclusions Ablation with irreversible electroporation is a new non-thermal ablation technique which has been demonstrated, both in the previously published studies and in the cases described in this paper, as a safe and efficient therapeutic method for patients with LAPC and CRLM.

Triage is implemented in healthcare settings to optimise access to appropriate care and manage waiting times. To determine the optimum features of triage systems for patients with musculoskeletal conditions. AMED, BNI, CINAHL, EMBASE, Health Business Elite, HMIC, MEDLINE, Cochrane Library, Web of Science and Google Scholar. Studies that included non-musculoskeletal conditions, concerned patients aged <18 years or were set in emergency departments were excluded. Study quality was graded using the Downs and Black quality index. Qualitative methods were used to further inform the findings of the literature review. Thirty-four studies met the inclusion criteria, with study quality ranging from eight to 24 out of a possible 27. Musculoskeletal triage is conducted via face-to-face consultation, paper referral letter or telephone consultation. Triage performed by physiotherapists, general practitioners, multidisciplinary teams, nurses, occupational therapists and speech therapists has been shown to be effective using a range of outcomes. Qualitative data revealed the value of supportive interdisciplinary teams, and suggested that this support is more important than choice of clinician. Patients trusted, and expressed preferences for, experienced clinicians to perform triage. Triage can be performed effectively via a number of methods and by a range of clinicians. Satisfaction, cost, diagnostic agreement, appropriateness of referral and waiting list time have been improved though triage. Multidisciplinary support mechanisms are critical elements of successful triage systems. Patients are more concerned with access issues than professional boundaries.

Many strategies have been recommended to support caregivers in communicating with people who live with dementia. However, less is known about what makes communication a good and meaningful experience from the perspective of people with dementia. Understanding this may enhance the person with dementia's sense of connectedness, strengthen their relationships, and facilitate person-centered care. The current review aimed to evaluate research that examined experiences of communication in people living with dementia. Studies that examined reports provided by people with dementia, healthcare professionals, and family caregivers were included. A mixed-methods systematic review was conducted using PsychINFO, MEDLINE, and EMBASE databases. After applying the eligibility criteria, 15 studies were included. Although eight of these recruited people with dementia, only one focused on their perspectives of communication experiences and the remaining studies focused on the perspectives of family caregivers and healthcare professionals. These studies either explored experiences without suggestions of communication methods, "open exploration," or through examining experiences of strategies, "exploration of strategies." A significant theme was around communication difficulties that affected interpersonal relationships and activities of daily living. Conversely, personhood strategies and a strong underlying relationship were believed to facilitate communication. The one study that examined the perspectives of people with dementia emphasized the importance of retaining valued relationships and feeling respected during communication. The need to involve people with dementia in research, particularly around their experiences of communication, is evident. Such research would be imperative for facilitating person-centered care, strengthening social relationships, and informing training programs.

Rapid Health and Needs assessments after disasters: a systematic review

PubMed Central

2010-01-01

Background Publichealth care providers, stakeholders and policy makers request a rapid insight into health status and needs of the affected population after disasters. To our knowledge, there is no standardized rapid assessment tool for European countries. The aim of this article is to describe existing tools used internationally and analyze them for the development of a workable rapid assessment. Methods A review was conducted, including original studies concerning a rapid health and/or needs assessment. The studies used were published between 1980 and 2009. The electronic databasesof Medline, Embase, SciSearch and Psychinfo were used. Results Thirty-three studies were included for this review. The majority of the studies was of US origin and in most cases related to natural disasters, especially concerning the weather. In eighteen studies an assessment was conducted using a structured questionnaire, eleven studies used registries and four used both methods. Questionnaires were primarily used to asses the health needs, while data records were used to assess the health status of disaster victims. Conclusions Methods most commonly used were face to face interviews and data extracted from existing registries. Ideally, a rapid assessment tool is needed which does not add to the burden of disaster victims. In this perspective, the use of existing medical registries in combination with a brief questionnaire in the aftermath of disasters is the most promising. Since there is an increasing need for such a tool this approach needs further examination. PMID:20515478

Evidence from systematic reviews demonstrates that multi-disciplinary rehabilitation is effective in the stroke population, in which older adults predominate. However, the evidence base for the effectiveness of rehabilitation following acquired brain injury (ABI) in younger adults has not been established, perhaps because this scenario presents different methodological challenges in research. To assess the effects of multi-disciplinary rehabilitation following ABI in adults 16 to 65 years of age. We ran the most recent search on 14 September 2015. We searched the Cochrane Injuries Group Specialised Register, The Cochrane Library, Ovid MEDLINE(R), Ovid MEDLINE(R) In-Process & Other Non-Indexed Citations, Ovid MEDLINE(R) Daily and Ovid OLDMEDLINE(R), Embase Classic+Embase (OvidSP), Web of Science (ISI WOS) databases, clinical trials registers, and we screened reference lists. Randomised controlled trials (RCTs) comparing multi-disciplinary rehabilitation versus routinely available local services or lower levels of intervention; or trials comparing an intervention in different settings, of different intensities or of different timing of onset. Controlled clinical trials were included, provided they met pre-defined methodological criteria. Three review authors independently selected trials and rated their methodological quality. A fourth review author would have arbitrated if consensus could not be reached by discussion, but in fact, this did not occur. As in previous versions of this review, we used the method described by Van Tulder 1997 to rate the quality of trials and to perform a 'best evidence' synthesis by attributing levels of evidence on the basis of methodological quality. Risk of bias assessments were performed in parallel using standard Cochrane methodology. However, the Van Tulder system provided a more discriminative evaluation of rehabilitation trials, so we have continued to use it for our primary synthesis of evidence. We subdivided trials in terms of severity of brain injury, setting and type and timing of rehabilitation offered. We identified a total of 19 studies involving 3480 people. Twelve studies were of good methodological quality and seven were of lower quality, according to the van Tulder scoring system. Within the subgroup of predominantly mild brain injury, 'strong evidence' suggested that most individuals made a good recovery when appropriate information was provided, without the need for additional specific interventions. For moderate to severe injury, 'strong evidence' showed benefit from formal intervention, and 'limited evidence' indicated that commencing rehabilitation early after injury results in better outcomes. For participants with moderate to severe ABI already in rehabilitation, 'strong evidence' revealed that more intensive programmes are associated with earlier functional gains, and 'moderate evidence' suggested that continued outpatient therapy could help to sustain gains made in early post-acute rehabilitation. The context of multi-disciplinary rehabilitation appears to influence outcomes. 'Strong evidence' supports the use of a milieu-oriented model for patients with severe brain injury, in which comprehensive cognitive rehabilitation takes place in a therapeutic environment and involves a peer group of patients. 'Limited evidence' shows that specialist in-patient rehabilitation and specialist multi-disciplinary community rehabilitation may provide additional functional gains, but studies serve to highlight the particular practical and ethical restraints imposed on randomisation of severely affected individuals for whom no realistic alternatives to specialist intervention are available. Problems following ABI vary. Consequently, different interventions and combinations of interventions are required to meet the needs of patients with different problems. Patients who present acutely to hospital with mild brain injury benefit from follow-up and appropriate information and advice. Those with moderate to severe brain injury benefit from routine follow-up so their needs for rehabilitation can be assessed. Intensive intervention appears to lead to earlier gains, and earlier intervention whilst still in emergency and acute care has been supported by limited evidence. The balance between intensity and cost-effectiveness has yet to be determined. Patients discharged from in-patient rehabilitation benefit from access to out-patient or community-based services appropriate to their needs. Group-based rehabilitation in a therapeutic milieu (where patients undergo neuropsychological rehabilitation in a therapeutic environment with a peer group of individuals facing similar challenges) represents an effective approach for patients requiring neuropsychological rehabilitation following severe brain injury. Not all questions in rehabilitation can be addressed by randomised controlled trials or other experimental approaches. For example, trial-based literature does not tell us which treatments work best for which patients over the long term, and which models of service represent value for money in the context of life-long care. In the future, such questions will need to be considered alongside practice-based evidence gathered from large systematic longitudinal cohort studies conducted in the context of routine clinical practice.

Background: This research aimed to systematically study and outline the methods of hospital performance evaluation used in Iran. Methods: In this systematic review, all Persian and English-language articles published in the Iranian and non-Iranian scientific journals indexed from Sep 2004 to Sep 2014 were studied. For finding the related articles, the researchers searched the Iranian electronic databases, including SID, IranMedex, IranDoc, Magiran, as well as the non-Iranian electronic databases, including Medline, Embase, Scopus, and Google Scholar. For reviewing the selected articles, a data extraction form, developed by the researchers was used. Results: The entire review process led to the selection of 51 articles. The publication of articles on the hospital performance evaluation in Iran has increased considerably in the recent years. Besides, among these 51 articles, 38 articles (74.51%) had been published in Persian language and 13 articles (25.49%) in English language. Eight models were recognized as evaluation model for Iranian hospitals. Totally, in 15 studies, the data envelopment analysis model had been used to evaluate the hospital performance. Conclusion: Using a combination of model to integrate indicators in the hospital evaluation process is inevitable. Therefore, the Ministry of Health and Medical Education should use a set of indicators such as the balanced scorecard in the process of hospital evaluation and accreditation and encourage the hospital managers to use them.

Objective To review, categorize, and synthesize findings from the literature about the application of health information technologies in geriatrics and gerontology (GGHIT). Materials and Methods This mixed-method systematic review is based on a comprehensive search of Medline, Embase, PsychInfo and ABI/Inform Global. Study selection and coding were performed independently by two researchers and were followed by a narrative synthesis. To move beyond a simple description of the technologies, we employed and adapted the diffusion of innovation theory (DOI). Results 112 papers were included. Analysis revealed five main types of GGHIT: (1) telecare technologies (representing half of the studies); (2) electronic health records; (3) decision support systems; (4) web-based packages for patients and/or family caregivers; and (5) assistive information technologies. On aggregate, the most consistent finding proves to be the positive outcomes of GGHIT in terms of clinical processes. Although less frequently studied, positive impacts were found on patients’ health, productivity, efficiency and costs, clinicians’ satisfaction, patients’ satisfaction and patients’ empowerment. Discussion Further efforts should focus on improving the characteristics of such technologies in terms of compatibility and simplicity. Implementation strategies also should be improved as trialability and observability are insufficient. Conclusions Our results will help organizations in making decisions regarding the choice, planning and diffusion of GGHIT implemented for the care of older adults. PMID:23666776

The performance of a drug in a clinical trial setting often does not reflect its effect in daily clinical practice. In this third of three reviews, we examine the applications that have been used in the literature to predict real-world effectiveness from randomized controlled trial efficacy data. We searched MEDLINE, EMBASE from inception to March 2014, the Cochrane Methodology Register, and websites of key journals and organisations and reference lists. We extracted data on the type of model and predictions, data sources, validation and sensitivity analyses, disease area and software. We identified 12 articles in which four approaches were used: multi-state models, discrete event simulation models, physiology-based models and survival and generalized linear models. Studies predicted outcomes over longer time periods in different patient populations, including patients with lower levels of adherence or persistence to treatment or examined doses not tested in trials. Eight studies included individual patient data. Seven examined cardiovascular and metabolic diseases and three neurological conditions. Most studies included sensitivity analyses, but external validation was performed in only three studies. We conclude that mathematical modelling to predict real-world effectiveness of drug interventions is not widely used at present and not well validated. © 2016 The Authors Research Synthesis Methods Published by John Wiley & Sons Ltd. © 2016 The Authors Research Synthesis Methods Published by John Wiley & Sons Ltd.

Early Prognostication Markers in Cardiac Arrest Patients Treated with Hypothermia

Karapetkova, Maria; Koenig, Matthew A.; Jia, Xiaofeng

2015-01-01

Background and purpose Established prognostication markers, such as clinical findings, electroencephalography (EEG), and biochemical markers, used by clinicians to predict neurologic outcome after cardiac arrest (CA) are altered under therapeutic hypothermia (TH) conditions and their validity remains uncertain. Methods MEDLINE and EMBASE were searched for evidence on the current standards for neurologic outcome prediction for out-of-hospital CA patients treated with TH and the validity of a wide range of prognostication markers. Relevant studies that suggested one or several established biomarkers, and multimodal approaches for prognostication were included and reviewed. Results While the prognostic accuracy of various tests has been questioned after TH, pupillary light reflexes and somatosensory evoked potentials (SSEP) are still strongly associated with negative outcome for early prognostication. Increasingly, EEG background activity has also been identified as a valid predictor for outcome after 72 hours after CA and a preferred prognostic method in clinical settings. Neuroimaging techniques, such as MRI and CT, can identify functional and structural brain injury, but are not readily available at the patient’s bedside because of limited availability and high costs. Conclusions A multimodal algorithm composed of neurological examination, EEG-based quantitative testing, and SSEP, in conjunction with newer MRI sequences, if available, holds promise for accurate prognostication in CA patients treated with TH. In order to avoid premature withdrawal of care, prognostication should be performed later than 72 hours after CA. PMID:26228521

This study systematically reviews the existing literature on the efficacy of adjuvant corticosteroids in improving clinical outcomes after peritonsillar abscess (PTA) drainage. Systematic review. We performed a literature search of MEDLINE, Cochrane Library, Cumulative Index to Nursing and Allied Health Literature, Web of Science, Scopus, Embase, and ClinicalTrials.gov from inception to June 2016. Inclusion criteria included randomized controlled trials (RCTs) evaluating adjuvant corticosteroids after PTA drainage. Data were systematically collected on study design, patient demographics, and clinical characteristics. Two independent investigators reviewed all manuscripts and summarized the data. Three RCTs comprising 153 patients were included. The results were not pooled due to heterogeneity in the method in which outcomes were measured and reported. The trials also varied on the type of steroid (dexamethasone, methylprednisolone) administered and method of drainage (incision, aspiration). All three RCTs reported statistically significant improvement in body temperature from adjuvant steroid administration compared to placebo. Pain scores, mouth opening, time to painless oral intake, and duration of hospitalization were significantly improved in only one or two of the three RCTs between the steroid and control group. No adverse side effects from steroid administration were reported. Steroids as an adjunct therapy to the treatment of PTA may result in faster recovery. However, further investigation with larger RCTs and standardized outcomes are warranted. 1a.

Background An emerging approach for investigating patient perspectives of their illness is the use of drawings. Objective This scoping review consolidates findings from current literature regarding the use of drawings to explore patients’ perceptions and experiences of their illness and treatment. Methods Electronic databases (Medline, PubMed, Embase, PsychINFO, Cinahl, Art Index and Scopus) and reference lists were searched to identify published English language studies using participant-generated drawings to explore adults’ perceptions and experiences of their illness and treatment. Using the scoping methodological framework, data were analyzed with respect to each study’s design, key findings and implications. Results Thirty-two studies were identified and these reflected diversities in both health conditions and methods of data collection and analysis. Participants’ drawings revealed new, insightful knowledge about patients’ perceptions, beliefs and experiences of their condition and were associated with clinical and psychological markers of health. Drawing was a powerful adjunct to traditional data collection approaches, and demonstrated potential benefits for participants. This review provides detailed insights and guidance on the use of drawings in research and clinical practice. Conclusion Drawing is a novel and potentially valuable technique for exploring patients’ perceptions and experiences about their illness and treatment. Advancing the methodology and applicability of drawings in this area will assist in the future development of this technique, with benefits for the patient, researcher and health care professional alike.

Objective To review the evidence on and estimate the risk of myocardial infarction and stroke in bipolar disorder. Method A systematic search using MEDLINE, EMBASE, PsycINFO, Web of Science, Scopus, Cochrane Database of Systematic Reviews, and bibliographies (1946 – May, 2013) was conducted. Case-control and cohort studies of bipolar disorder patients age 15 or older with myocardial infarction or stroke as outcomes were included. Two independent reviewers extracted data and assessed quality. Estimates of effect were summarized using random-effects meta-analysis. Results Five cohort studies including 13 115 911 participants (27 092 bipolar) were included. Due to the use of registers, different statistical methods, and inconsistent adjustment for confounders, there was significant methodological heterogeneity among studies. The exploratory meta-analysis yielded no evidence for a significant increase in the risk of myocardial infarction: [relative risk (RR): 1.09, 95% CI 0.96–1.24, P = 0.20; I2 = 6%]. While there was evidence of significant study heterogeneity, the risk of stroke in bipolar disorder was significantly increased (RR 1.74, 95% CI 1.29–2.35; P = 0.0003; I2 = 83%). Conclusion There may be a differential risk of myocardial infarction and stroke in patients with bipolar disorder. Confidence in these pooled estimates was limited by the small number of studies, significant heterogeneity and dissimilar methodological features. PMID:24850482

Irreversible electroporation is a new, non-thermal ablation technique in the treatment of parenchymal organ tumors which uses short high voltage pulses of electricity in order to induce apoptosis of targeted cells. In this paper the application of this method of treatment in locally advanced pancreatic cancer (LAPC) and liver cancer is analyzed. Between 04.2014 and 09.2014 two patients with LAPC and one with colorectal liver metastasis (CRLM) were qualified for treatment with irreversible electroporation. Both patients remained under constant observation and control. PubMed/Medline, Embase and Google Scholar databases were searched and eight original reports on irreversible electroporation of pancreatic and liver tumors based on the biggest groups of patients were found. Two patients with LAPC and one with CRLM were qualified for ablation with irreversible electroporation. In all three patients a successful irreversible electroporation (IRE) procedure of the whole tumor was conducted. In the minimum seven-month follow-up 100% local control was achieved - without progression. In the literature review the local response to treatment ranged from 41% to 100%. The event-free survival rate in six-month observation was 94%. Ablation with irreversible electroporation is a new non-thermal ablation technique which has been demonstrated, both in the previously published studies and in the cases described in this paper, as a safe and efficient therapeutic method for patients with LAPC and CRLM.

This paper assessed the evidence of Panax notoginseng preparations in patients suffering from UAP using meta-analysis and systematic review methods. Methods were according to the Cochrane Handbook and analysed using Revman 5.3. A search of PubMed, Cochrane Library, Embase, MEDLINE, Chinese national knowledge infrastructure (CNKI), Vip information database, Wanfang data and Chinese Biomedical Literature Database (SinoMed) was conducted to identify randomized controlled trials (RCTs) of P. notoginseng preparations on UAP regardless of blinding, sex and language. The outcomes include all-cause mortality, cardiac mortality, cardiovascular events, UAP symptoms, improvement of electrocardiogram and adverse events. Eighteen RCTs including 1828 patients were identified. The level of reporting is generally poor. Among 18 studies, 16 studies were prescribed P. notoginseng injections, and two studies were oral P. notoginseng preparations. Reduction of cardiovascular events (RR:0.35;95% CI:0.13 to 0.94), alleviation of angina pectoris symptoms (RR:1.23;95% CI 1.18 to 1.29), improvement of ECG (RR:1.22;95% CI 1.15 to 1.28) and reduced frequency of angina pectoris (MD:-1.48; 95% CI -2.49 to -0.48) were observed. Cardiac mortality and duration of angina pectoris were not statistically significant. Panax notoginseng is beneficial to UAP patients; the results of these reviews may have important implications to clinical work. Copyright © 2017 John Wiley & Sons, Ltd.

Labrague, Leodoro J; McEnroe-Petitte, Denise M

2017-12-01

Nurse education plays a critical role in the achievement of conflict management skills in nursing students. However, a wider perspective on this concept has not been explored. This paper is a report of a review appraising and synthesizing existing empirical studies describing conflict management styles among nursing students. An integrative review method guided this review. Five (5) bibliographic databases (CINAHL, Medline, Psych Info, Embase and SCOPUS) were searched to locate relevant articles. An electronic database search was performed in December 2016 to locate studies published from 2007 onwards. The search words included: 'conflict', 'management resolution', 'management style', 'management strategy', 'nursing', 'student'. Thirteen (13) articles met the inclusion criteria. Nursing students preferred 'constructive/positive conflict management styles' when handling conflicts. However, more studies are needed to identify factors that may affect their choice of styles. Further, this review emphasizes the need for empirical studies to identify appropriate interventions that would effectively enhance nursing students' skills in managing conflicts using rigorous methods. Nursing faculty play a critical role in teaching, training, and modeling constructive conflict resolution styles in nursing students. Simulation scenarios, reflective exercises, and role playing may be useful to facilitate such learning in choosing constructive conflict management styles. Structured training programme on conflict management will assist nursing students develop positive conflict management styles. Copyright © 2017 Elsevier Ltd. All rights reserved.

The quality of systematic reviews of health economic evaluations (SR-HE) is often limited because of methodological shortcomings. One reason for this poor quality is that there are no established standards for the preparation of SR-HE. The objective of this study is to compare existing methods and suggest best practices for the preparation of SR-HE. To identify the relevant methodological literature on SR-HE, a systematic literature search was performed in Embase, Medline, the National Health System Economic Evaluation Database, the Health Technology Assessment Database, and the Cochrane methodology register, and webpages of international health technology assessment agencies were searched. The study selection was performed independently by 2 reviewers. Data were extracted by one reviewer and verified by a second reviewer. On the basis of the overlaps in the recommendations for the methods of SR-HE in the included papers, suggestions for best practices for the preparation of SR-HE were developed. Nineteen relevant publications were identified. The recommendations within them often differed. However, for most process steps there was some overlap between recommendations for the methods of preparation. The overlaps were taken as basis on which to develop suggestions for the following process steps of preparation: defining the research question, developing eligibility criteria, conducting a literature search, selecting studies, assessing the methodological study quality, assessing transferability, and synthesizing data. The differences in the proposed recommendations are not always explainable by the focus on certain evaluation types, target audiences, or integration in the decision process. Currently, there seem to be no standard methods for the preparation of SR-HE. The suggestions presented here can contribute to the harmonization of methods for the preparation of SR-HE. © The Author(s) 2014.

Introduction Rapid reviews (RR), using abbreviated systematic review (SR) methods, are becoming more popular among decision-makers. This World Health Organization commissioned study sought to summarize RR methods, identify differences, and highlight potential biases between RR and SR. Methods Review of RR methods (Key Question 1 [KQ1]), meta-epidemiologic studies comparing reliability/ validity of RR and SR methods (KQ2), and their potential associated biases (KQ3). We searched Medline, EMBASE, Cochrane Library, grey literature, and checked reference lists, used personal contacts, and crowdsourcing (e.g. email listservs). Selection and data extraction was conducted by one reviewer (KQ1) or two reviewers independently (KQ2-3). Results Across all KQs, we identified 42,743 citations through the literature searches. KQ1: RR methods from 29 organizations were reviewed. There was no consensus on which aspects of the SR process to abbreviate. KQ2: Studies comparing the conclusions of RR and SR (n = 9) found them to be generally similar. Where major differences were identified, it was attributed to the inclusion of evidence from different sources (e.g. searching different databases or including different study designs). KQ3: Potential biases introduced into the review process were well-identified although not necessarily supported by empirical evidence, and focused mainly on selective outcome reporting and publication biases. Conclusion RR approaches are context and organization specific. Existing comparative evidence has found similar conclusions derived from RR and SR, but there is a lack of evidence comparing the potential of bias in both evidence synthesis approaches. Further research and decision aids are needed to help decision makers and reviewers balance the benefits of providing timely evidence with the potential for biased findings. PMID:27930662

To provide a comprehensive and objective summary of contraceptive failure rates for a variety of methods based on a systematic review of the literature. Medline and Embase were searched using the Ovid interface from January 1990 to February 2008, as well as the reference lists of published articles, to identify studies reporting contraceptive efficacy as a Pearl Index or life-table estimate. Reports that recruited less than 400 subjects per study group and those covering less than six cycles/six months were excluded. In addition, unlicensed products or those not internationally available, emergency contraception, and vasectomy studies were excluded. Information was identified and extracted from 139 studies. One-year Pearl Indices reported for short-acting user-dependent hormonal methods were generally less than 2.5. Gross life-table rates for long-acting hormonal methods (implants and the levonorgestrel releasing-intrauterine system [LNG-IUS]) generally ranged between 0-0.6 per 100 at one year, but wider ranges (0.1-1.5 per 100) were observed for the copper intrauterine devices (0.1-1.4 per 100 for Cu-UIDs with surface area ≥ 300 mm2 and 0.6-1.5 per 100 for those with surface area < 300 mm2). Barrier and natural methods were the least effective. Our review broadly confirms the hierarchy of contraceptive effectiveness in descending order as: (1) female sterilisation, long-acting hormonal contraceptives (LNG-IUS and implants); (2) Cu-IUDs with ≥ 300 mm2 surface area; (3) Cu-IUDs with < 300 mm2 surface area and short-acting hormonal contraceptives ( injectables, oral contraceptives, the patch and vaginal rings), (4) barrier methods and natural methods.

Surgical site infection (SSI) remains a significant source of morbidity in spine surgery, with reported rates varying from 0.7 to 16%. To systematically review and evaluate the evidence for strategies for prophylaxis of SSI in adult spine surgery in the last twenty years. Two independent systematic searches were conducted, at two international spine centers, encompassing PubMed, ClinicalTrials.gov, Cochrane Database, EBSCO Medline, ScienceDirect, Ovid Medline, EMBASE (Ovid), and MEDLINE. References were combined and screened, then distilled to 69 independent studies for final review. 11 randomized controlled trials (RCTs), 51 case-controlled studies (CCS), and 7 case series were identified. Wide variation exists in surgical indications, approaches, procedures, and even definitions of SSI. Intra-wound vancomycin powder was the most widely studied intervention (19 studies, 1 RCT). Multiple studies examined perioperative antibiotic protocols, closed-suction drainage, povidone-iodine solution irrigation, and 2-octyl-cyanoacrylate skin closure. 18 interventions were examined by a single study only. There is limited evidence for the efficacy of intra-wound vancomycin. There is strong evidence that closed-suction drainage does not affect SSI rates, while there is moderate evidence for the efficacy of povidone-iodine irrigation and that single-dose preoperative antibiotics is as effective as multiple doses. Few conclusions can be drawn about other interventions given the paucity and poor quality of studies. While a small body of evidence underscores a select few interventions for SSI prophylaxis in adult spine surgery, most proposed measures have not been investigated beyond a single study. Further high level evidence is required to justify SSI preventative treatments. Copyright © 2018 Elsevier Ltd. All rights reserved.

Objectives: The objective was to introduce the MedlinePlus Website to the predominantly Hispanic residents of the Lower Rio Grande Valley region of Texas by partnering with a health professions magnet high school (known as Med High). Methods: Community assessment was used in the planning stages and included pre-project focus groups with students and teachers. Outreach methods included peer tutor selection, train-the-trainer sessions, school and community outreach, and pre- and posttests of MedlinePlus training sessions. Evaluation methods included Web statistics; end-of-project interviews; focus groups with students, faculty, and librarians; and end-of-project surveys of students and faculty. Results: Four peer tutors reached more than 2,000 people during the project year. Students and faculty found MedlinePlus to be a useful resource. Faculty and librarians developed new or revised teaching methods incorporating MedlinePlus. The project enhanced the role of school librarians as agents of change at Med High. The project continues on a self-sustaining basis. Conclusions: Using peer tutors is an effective way to educate high school students about health information resources and, through the students, to reach families and community members.

2008-01-01

The integration of disparate research domains is a prerequisite for the success of the translational science initiative. MEDLINE abstracts contain content from a broad range of disciplines, presenting an opportunity for the development of methods able to integrate the knowledge they contain. Latent Semantic Analysis (LSA) and related methods learn human-like associations between terms from unannotated text. However, their computational and memory demands limits their ability to address a corpus of this size. Furthermore, visualization methods previously used in conjunction with LSA have limited ability to define the local structure of the associative networks LSA learns. This paper explores these issues by (1) processing the entire MEDLINE corpus using Random Indexing, a variant of LSA, and (2) exploring learned associations using Pathfinder Networks. Meaningful associations are inferred from MEDLINE, including a drug-disease association undetected by PUBMED search. PMID:18999236

Fernandez, Melissa A; Cloutier, Geneviève; Lebel, Alexandre

2018-01-01

Background Since the 1990s, urban agriculture (UA) has contributed to improving food security in low- and middle- income countries. Now, it is implemented as a multifunctional intervention that can influence various determinants of health (eg, food security, social relationships). Studies of interest stem from several research disciplines, use a wide range of methods, and show results that are sometimes inconsistent. Current studies have not summarized the overall effects of UA on health and its determinants. Objective The objective of this protocol is to develop a research strategy for a scoping review that characterizes studies of beneficial and adverse impacts of UA on health and its determinants in a wide range of disciplines. Methods Initially, with the help of a library specialist, a list of publications will be obtained through a systematic search of seven electronic bibliographic databases: PubMed, Embase, MEDLINE (Embase), CINAHL Plus with full text, Academic Search Premier (EBSCO host), CAB Abstract (Ovid), and Web of Science. Secondly, a three-step screening by two independent reviewers will lead to a list of relevant publications that meet eligibility and inclusion criteria. Finally, data on the bibliography, type of participants, type of study, results of study, and countries will be extracted from included articles and analyzed to be presented in a peer-reviewed article. Results The findings are expected to identify research gaps that will inform needs for UA research in specific fields (eg, mental health), among certain population groups (eg, adults) or within different economic contexts (eg, low-, middle-, or high-income countries). Furthermore, the findings are expected to identify knowledge gaps and direct future research needs. Conclusions This is an original study that seeks to integrate beneficial and adverse effects of UA on health at different level of influence (individuals, households, and community) in order to facilitate a better understanding of UA impacts. This protocol is a first of its kind and is expected to lead to a characterization of UA impacts based on sociodemographic profiles of participants and income levels of the studied countries. This will be relevant for policy makers and UA practitioners. PMID:29588270

Reducing Alaska Native paediatric oral health disparities: a systematic review of oral health interventions and a case study on multilevel strategies to reduce sugar-sweetened beverage intake

Chi, Donald L.

2013-01-01

Background Tooth decay is the most common paediatric disease and there is a serious paediatric tooth decay epidemic in Alaska Native communities. When untreated, tooth decay can lead to pain, infection, systemic health problems, hospitalisations and in rare cases death, as well as school absenteeism, poor grades and low quality-of-life. The extent to which population-based oral health interventions have been conducted in Alaska Native paediatric populations is unknown. Objective To conduct a systematic review of oral health interventions aimed at Alaska Native children below age 18 and to present a case study and conceptual model on multilevel intervention strategies aimed at reducing sugar-sweetened beverage (SSB) intake among Alaska Native children. Design Based on the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) Statement, the terms “Alaska Native”, “children” and “oral health” were used to search Medline, Embase, Web of Science, GoogleScholar and health foundation websites (1970–2012) for relevant clinical trials and evaluation studies. Results Eighty-five studies were found in Medline, Embase and Web of Science databases and there were 663 hits in GoogleScholar. A total of 9 publications were included in the qualitative review. These publications describe 3 interventions that focused on: reducing paediatric tooth decay by educating families and communities; providing dental chemotherapeutics to pregnant women; and training mid-level dental care providers. While these approaches have the potential to improve the oral health of Alaska Native children, there are unique challenges regarding intervention acceptability, reach and sustainability. A case study and conceptual model are presented on multilevel strategies to reduce SSB intake among Alaska Native children. Conclusions Few oral health interventions have been tested within Alaska Native communities. Community-centred multilevel interventions are promising approaches to improve the oral and systemic health of Alaska Native children. Future investigators should evaluate the feasibility of implementing multilevel interventions and policies within Alaska Native communities as a way to reduce children's health disparities.

In this review we describe recent developments in the field of radiomics along with current relevant literature linking it to tumor biology. We furthermore explore the methodologic quality of these studies with our in-house radiomics quality scoring (RQS) tool. Finally, we offer our vision on necessary future steps for the development of stable radiomic features and their links to tumor biology. Two authors (S.S. and H.W.) independently performed a thorough systematic literature search and outcome extraction to identify relevant studies published in MEDLINE/PubMed (National Center for Biotechnology Information, NCBI), EMBASE (Ovid) and Web of Science (WoS). Two authors (S.S, H.W) separately and two authors (J.v.T and E.d.J) concordantly scored the articles for their methodology and analyses according to the previously published radiomics quality score (RQS). In summary, a total of 655 records were identified till 25-09-2017 based on the previously specified search terms, from which n = 236 in MEDLINE/PubMed, n = 215 in EMBASE and n = 204 from Web of Science. After determining full article availability and reading the available articles, a total of n = 41 studies were included in the systematic review. The RQS scoring resulted in some discrepancies between the reviewers, e.g. reviewer H.W scored 4 studies ≥50%, reviewer S.S scored 3 studies ≥50% while reviewers J.v.T and E.d.J scored 1 study ≥50%. Up to nine studies were given a quality score of 0%. The majority of studies were scored below 50%. In this study, we performed a systematic literature search linking radiomics to tumor biology. All but two studies (n = 39) revealed that radiomic features derived from ultrasound, CT, PET and/or MR are significantly associated with one or several specific tumor biologic substrates, from somatic mutation status to tumor histopathologic grading and metabolism. Considerable inter-observer differences were found with regard to RQS scoring, while important questions were raised concerning the interpretability of the outcome of such scores.

Yeung, M F; Tang, William Y M

2015-12-01

Pepper (oleoresin capsicum) spray is one of the most common riot-control measures used today. Although not lethal, exposure of pepper spray can cause injury to different organ systems. This review aimed to summarise the major clinicopathological effects of pepper spray in humans. MEDLINE, EMBASE database, and Cochrane Database of Systematic Reviews were used to search for terms associated with the clinicopathological effects of pepper spray in humans and those describing the pathophysiology of capsaicin. A phone interview with two individuals recently exposed to pepper spray was also conducted to establish clinical symptoms. Major key words used for the MEDLINE search were "pepper spray", "OC spray", "oleoresin capsicum"; and other key words as "riot control agents", "capsaicin", and "capsaicinoid". We then combined the key words "capsaicin" and "capsaicinoid" with the major key words to narrow down the number of articles. A search with other databases including EMBASE and Cochrane Database of Systematic Reviews was also conducted with the above phrases to identify any additional related articles. All article searches were confined to human study. The bibliography of articles was screened for additional relevant studies including non-indexed reports, and information from these was also recorded. Non-English articles were included in the search. Fifteen articles were considered relevant. Oleoresin capsicum causes almost instantaneous irritative symptoms to the skin, eyes, and respiratory system. Dermatological effects include a burning sensation, erythema, and hyperalgesia. Ophthalmic effects involve blepharospasm, conjunctivitis, peri-orbital oedema, and corneal pathology. Following inhalation, a stinging or burning sensation can be felt in the nose with sore throat, chest tightness, or dyspnoea. The major pathophysiology is neurogenic inflammation caused by capsaicinoid in the pepper spray. There is no antidote for oleoresin capsicum. Treatment consists of thorough decontamination, symptom-directed supportive measures, and early detection and treatment of systemic toxicity. Decontamination should be carefully carried out to avoid contamination of the surrounding skin and clothing. Pepper (oleoresin capsicum) spray is an effective riot-control agent and does not cause life-threatening clinical effects in the majority of exposed individuals. Early decontamination minimises the irritant effects.

To evaluate the safety profile of nicergoline compared with placebo and other active agents from published randomised controlled trials. Systematic review and meta-analysis of nicergoline compared with placebo and other active agents across various indications. MEDLINE, Medline-in-process, Cochrane, EMBASE, EMBASE alerts, Cochrane Central Register of Controlled Trials (CENTRAL), Cochrane Database of Systematic Reviews (CDSR) and Cochrane Methodology Register (CMR) for all the randomised controlled trials, open-label or blinded, in adults treated with nicergoline. Studies published until August 2013 were included. 29 studies were included for data extraction. The studies included in this review were majorly from European countries and mostly in cerebrovascular disease (n=15) and dementia (n=8). The treatment withdrawals were comparatively lower in the nicergoline group as compared with the placebo group (RR=0.92; 95% CI 0.7 to 1.21) and other active comparators (RR=0.45; 95% CI 0.10 to 1.95), but the difference was non-significant. Incidence of any adverse events (AEs) was slightly higher (RR=1.05; 95% CI 0.93 to 1.2) while incidence of serious AEs was lower (RR=0.85; 95% CI 0.50 to 1.45) in the nicergoline compared with placebo group. Frequency of anxiety was significantly lower in nicergoline as compared with placebo (p=0.01). Other AEs including diarrhoea, gastric upset, dizziness and drowsiness were less frequent in the nicergoline group when compared with placebo/active drugs, but the difference was non-significant. Frequency of hypotension and hot flushes was slightly higher in the nicergoline group but the difference was non-significant. None of the studies reported any incidence of fibrosis or ergotism with nicergoline treatment. Nicergoline is an ergot derivative, but its safety profile is better than other ergot derivatives like ergotamine and ergotoxine. This systematic review and meta-analysis suggests that nicergoline has a good safety profile. None of the studies included in this systematic review reported any incidence of fibrosis or ergotism with nicergoline. Published by the BMJ Publishing Group Limited.

2014-01-01

Background Many programmes to detect and prevent cardiovascular disease (CVD) have been performed, but the optimal strategy is not yet clear. Aim To present a systematic review of cardiometabolic screening programmes performed among apparently healthy people (not yet known to have CVD, diabetes, or cardiometabolic risk factors) and mixed populations (apparently healthy people and people diagnosed with risk factor or disease) to define the optimal screening strategy. Design and setting Systematic review of studies performed in primary care in Western countries. Method MEDLINE, Embase, and CINAHL databases were searched for studies screening for increased cardiometabolic risk. Exclusion criteria were studies designed to assess prevalence of risk factors without follow-up or treatment; without involving a GP; when fewer than two risk factors were considered as the primary outcome; and studies constrained to ethnic minorities. Results The search strategy yielded 11 445 hits; 26 met the inclusion criteria. Five studies (1995–2012) were conducted in apparently healthy populations: three used a stepwise method. Response rates varied from 24% to 79%. Twenty-one studies (1967–2012) were performed in mixed populations; one used a stepwise method. Response rates varied from 50% to 75%. Prevalence rates could not be compared because of heterogeneity of used thresholds and eligible populations. Observed time trends were a shift from mixed to apparently healthy populations, increasing use of risk scores, and increasing use of stepwise screening methods. Conclusion The optimal screening strategy in primary care is likely stepwise, in apparently healthy people, with the use of risk scores.

AIM To summarize the current knowledge on vascular complications and deep venous thrombosis (DVT) prophylaxis after anterior cruciate ligament (ACL) reconstruction. METHODS A systematic review was conducted according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses statement. MEDLINE, EMBASE, Cochrane, Web of Science, CINAHL, PubMed publisher, and Google scholar medical literature databases were searched up to November 10, 2015. Any arthroscopic surgical method of primary or revision intra-articular ACL reconstruction of all graft types in humans was included. A risk of bias assessment was determined. RESULTS Fourty-seven studies were included in the review. Pseudaneurysms were the most frequently reported arterial complication after ACL reconstruction, irrespective of graft type or method of graft fixation with an incidence of 0.3%. The time to diagnosis of arterial complications after ACL reconstruction varied from days to mostly weeks but even years. After ACL reconstruction without thromboprophylaxis, the incidence of DVT was 9.7%, of which 2.1% was symptomatic. The incidence of pulmonary embolism was 0.1%. Tourniquet time > 2 h was related to venous thromboembolism. Thromboprophylaxis is indicated in patients with risk factors for venous thromboembolism. CONCLUSION After ACL reconstruction, the incidence of arterial complications, symptomatic DVT and pulmonary embolism was 0.3%, 2.1% and 0.1% respectively. Arterial complications may occur with all types of arthroscopic ACL reconstruction, methods of graft fixation as well as any type of graft. Patients considered to be at moderate or high risk of venous thromboembolism should routinely receive thromboprophylaxis after ACL reconstruction. PMID:27672574

Tobacco smoking is one of the greatest causes of mortality in the world, responsible for over 5 million deaths per annum. The prevalence of smoking is over 1 billion people, with the majority coming from low or middle income countries. Yet, the incidence of smoking varies vastly between many countries. Some countries have been able to decline the smoking and tobacco related morbidity and mortality through the introduction of health promotion initiatives and effective policies in order to combat tobacco usage. However, on the other hand, in some countries, the incidence of smoking is increasing still further. With the growing body of evidence of detriment of tobacco to health, many control policies have been implemented as health promotion actions. Such methods include taxation of smoking, mass advertising campaigns in the media, peer education programs, community mobilization, motivational interviewing, health warnings on tobacco products, marketing restrictions, and banning smoking in public places. However, the review of the effectiveness of various health promotion methods used for smoking prevention and cessation is lacking. Therefore, the aim of this review is to identify and critically review the effectiveness of health promotion methods used for smoking prevention and cessation. All available studies and reports published were considered. Searches were conducted using PubMed, MEDLINE, Ovid, Karger, ProQuest, Sage Journals, Science Direct, Springer, Taylor and Francis, EMBASE, CINAHL, and Cochrane and Wiley Online Library. Various relevant search terms and keywords were used. After considering the inclusion and exclusion criteria, we selected 23 articles for the present review. PMID:26941908

This study aims to systematically review the different methods used for wear measurement of dental tissues and materials in clinical studies, their relevance and reliability in terms of accuracy and precision, and the performance of the different steps of the workflow taken independently. An exhaustive search of clinical studies related to wear of dental tissues and materials reporting a quantitative measurement method was conducted. MedLine, Embase, Scopus, Cochrane Library and Web of Science databases were used. Prospective studies, pilot studies and case series (>10 patients), as long as they contained a description of wear measurement methodology. Only studies published after 1995 were considered. After duplicates' removal, 495 studies were identified, and 41 remained for quantitative analysis. Thirty-four described wear-measurement protocols, using digital profilometry and superimposition, whereas 7 used alternative protocols. A specific form was designed to analyze the risk of bias. The methods were described in terms of material analyzed; study design; device used for surface acquisition; matching software details and settings; type of analysis (vertical height-loss measurement vs volume loss measurement); type of area investigated (entire occlusal area or selective areas); and results. There is a need of standardization of clinical wear measurement. Current methods exhibit accuracy, which is not sufficient to monitor wear of restorative materials and tooth tissues. Their performance could be improved, notably limiting the use of replicas, using standardized calibration procedures and positive controls, optimizing the settings of scanners and matching softwares, and taking into account unusable data.

To evaluate research priority setting approaches in childhood chronic diseases and to describe the priorities of stakeholders including patients, caregivers/families and health professionals. We conducted a systematic review of MEDLINE, Embase, PsycINFO and CINAHL from inception to 16 October 2016. Studies that elicited stakeholder priorities for paediatric chronic disease research were eligible for inclusion. Data on the prioritisation process were extracted using an appraisal checklist. Generated priorities were collated into common topic areas. We identified 83 studies (n=15 722). Twenty (24%) studies involved parents/caregivers and four (5%) children. The top three health areas were cancer (11%), neurology (8%) and endocrine/metabolism (8%). Priority topic areas were treatment (78%), disease trajectory (48%), quality of life/psychosocial impact (48%), disease onset/prevention (43%), knowledge/self-management (33%), prevalence (30%), diagnostic methods (28%), access to healthcare (25%) and transition to adulthood (12%). The methods included workshops, Delphi techniques, surveys and focus groups/interviews. Specific methods for collecting and prioritising research topics were described in only 60% of studies. Most reviewed studies were conducted in high-income nations. Research priority setting activities in paediatric chronic disease cover many discipline areas and have elicited a broad range of topics. However, child/caregiver involvement is uncommon, and the methods often lack clarity. A systematic and explicit process that involves patients and families in partnership may help to inform a more patient and family-relevant research agenda in paediatric chronic disease. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Systematic reviews provide clinicians and policymakers estimates of diagnostic test accuracy and their usefulness in clinical practice. We identified all available systematic reviews of diagnosis in endocrinology, summarized the diagnostic accuracy of the tests included, and assessed the credibility and clinical usefulness of the methods and reporting. We searched Ovid MEDLINE, EMBASE, and Cochrane CENTRAL from inception to December 2015 for systematic reviews and meta-analyses reporting accuracy measures of diagnostic tests in endocrinology. Experienced reviewers independently screened for eligible studies and collected data. We summarized the results, methods, and reporting of the reviews. We performed subgroup analyses to categorize diagnostic tests as most useful based on their accuracy. We identified 84 systematic reviews; half of the tests included were classified as helpful when positive, one-fourth as helpful when negative. Most authors adequately reported how studies were identified and selected and how their trustworthiness (risk of bias) was judged. Only one in three reviews, however, reported an overall judgment about trustworthiness and one in five reported using adequate meta-analytic methods. One in four reported contacting authors for further information and about half included only patients with diagnostic uncertainty. Up to half of the diagnostic endocrine tests in which the likelihood ratio was calculated or provided are likely to be helpful in practice when positive as are one-quarter when negative. Most diagnostic systematic reviews in endocrine lack methodological rigor, protection against bias, and offer limited credibility. Substantial efforts, therefore, seem necessary to improve the quality of diagnostic systematic reviews in endocrinology.

Summary Objectives To examine if human factors methods were applied in the design, development, and evaluation of mobile applications developed to facilitate aspects of patient-centered care coordination. Methods We searched MEDLINE and EMBASE (2013-2014) for studies describing the design or the evaluation of a mobile health application that aimed to support patients’ active involvement in the coordination of their care. Results 34 papers met the inclusion criteria. Applications ranged from tools that supported self-management of specific conditions (e.g. asthma) to tools that provided coaching or education. Twelve of the 15 papers describing the design or development of an app reported the use of a human factors approach. The most frequently used methods were interviews and surveys, which often included an exploration of participants’ current use of information technology. Sixteen papers described the evaluation of a patient application in practice. All of them adopted a human factors approach, typically an examination of the use of app features and/or surveys or interviews which enquired about patients’ views of the effects of using the app on their behaviors (e.g. medication adherence), knowledge, and relationships with healthcare providers. No study in our review assessed the impact of mobile applications on health outcomes. Conclusion The potential of mobile health applications to assist patients to more actively engage in the management of their care has resulted in a large number of applications being developed. Our review showed that human factors approaches are nearly always adopted to some extent in the design, development, and evaluation of mobile applications. PMID:26293851

Background and aims Skin rejuvenation is one of high demand cosmetic interventions in Iran. Fractional CO2 Laser is a high power ablative laser which has variety of utilization in medicine including treatment of acne scars and rejuvenation. The aim of this study was to evaluate the safety, efficacy, and cost-effectiveness of Fractional CO2 Laser in comparison with other methods of rejuvenation and acne scar treatment. Methods A systematic database search including Medline (via OVID and PubMed), EMBASE, CINHAL, Cochrane Library, CRD, SCOPUS and Web of Science conducted. After screening search results, selected publications appraised by CASP and Cochrane Collaboration's tool for assessing risk of bias and eligible studies included in the systematic review. In economic evaluation, all costs and benefits analyzed from Iran ministry of health's perspective. Results From 2667 publications, two randomized control trials were eligible and included in the study. The affectivity and complications of Fractional CO2 laser were comparable with Er: YAG but Fractional CO2 laser was 14.7% (P=0.01) more effective than Q-Switched ND: YAG laser. Cost affectivity of this method was the same as other alternative lasers. Conclusions Fractional CO2 laser is an effective and safe method for curing several kinds of skin. Never the less there was not sufficient evidence to support its advantage. This device has equal or lower price in comparison to competent technologies except for the non- fractional ablative Co2 laser that has the same or lower price and comparable effects.

BACKGROUND: Evidence regarding the effectiveness of incentive spirometry (ISy) on postoperative pulmonary outcomes after thoracic, cardiac and abdominal surgery remains inconclusive. This is attributed to various methodological issues inherent in ISy trials. Patient compliance has also been highlighted as a possible confounding factor; however, the status of evidence regarding patient compliance in these trials is unknown. OBJECTIVE: To explore the status of evidence on patient compliance with ISy interventions in randomized controlled trials (RCTs) in the above contexts. METHOD: A systematic search using MEDLINE, EMBASE and CINAHL databases was conducted to obtain relevant RCTs from 1972 to 2015 using the inclusion criteria. These were examined for specific ISy parameters, methods used for determining compliance and reporting on compliance. Main outcome measures were comparison of ISy parameters prescribed and assessed, and reporting on compliance. RESULTS: Thirty-six relevant RCTs were obtained. Six ISy parameters were identified in ISy prescriptions from these trials. Almost all (97.2%) of the trials had ISy prescriptions with specific parameters. Wilcoxon signed-rank test revealed that the ISy parameters assessed were significantly lower (Z=−5.433; P<0.001) than those prescribed; 66.7% of the trials indicated use of various methods to assess these parameters. Only six (16.7%) trials included reports on compliance; however, these were also incomprehensive. CONCLUSIONS: There is a scarcity and inconsistency of evidence regarding ISy compliance. Compliance data should be obtained using reliable and standardized methods to facilitate comparisons between and among trials. These should be reported comprehensively to facilitate valid inferences regarding ISy intervention effectiveness. PMID:26909010

Objective To systematically review the available evidence on the efficacy of the Pilates method in patients with chronic nonspecific low back pain. Method Searches were performed in MEDLINE, EMBASE, PEDro, SciELO, LILACS, CINAHL and CENTRAL in March 2013. Randomized controlled trials that tested the effectiveness of the Pilates method (against a nontreatment group, minimal intervention or other types of interventions) in adults with chronic low back pain were included regardless the language of publication. The outcome data were extracted from the eligible studies and were combined using a meta-analysis approach. Results The searches identified a total of 1,545 articles. From these, eight trials were considered eligible, and seven trials were combined in the meta-analysis. The comparison groups were as follows: Pilates versus other types of exercises (n=2 trials), and Pilates versus no treatment group or minimal intervention (n=4 trials) for short term pain; Pilates versus minimal intervention for short-term disability (n=4).We determined that Pilates was not better than other types of exercises for reducing pain intensity. However, Pilates was better than a minimal intervention for reducing short-term pain and disability (pain: pooled mean difference=1.6 points; 95% CI 1.4 to 1.8; disability: pooled mean difference=5.2 points; 95% CI 4.3 to 6.1). Conclusions Pilates was better than a minimal intervention for reducing pain and disability in patients with chronic low back pain. Pilates was not better than other types of exercise for short-term pain reduction. PMID:24346291

Continuous assessment of individual performance of doctors is crucial for life-long learning and quality of care. Policy-makers and health educators should have good insights into the strengths and weaknesses of the methods available. The aim of this study was to systematically evaluate the feasibility of methods, the psychometric properties of instruments that are especially important for summative assessments, and the effectiveness of methods serving formative assessments used in routine practise to assess the performance of individual doctors. We searched the MEDLINE (1966-January 2006), PsychINFO (1972-January 2006), CINAHL (1982-January 2006), EMBASE (1980-January 2006) and Cochrane (1966-2006) databases for English language articles, and supplemented this with a hand-search of reference lists of relevant studies and bibliographies of review articles. Studies that aimed to assess the performance of individual doctors in routine practise were included. Two reviewers independently abstracted data regarding study design, setting and findings related to reliability, validity, feasibility and effectiveness using a standard data abstraction form. A total of 64 articles met our inclusion criteria. We observed 6 different methods of evaluating performance: simulated patients; video observation; direct observation; peer assessment; audit of medical records, and portfolio or appraisal. Peer assessment is the most feasible method in terms of costs and time. Little psychometric assessment of the instruments has been undertaken so far. Effectiveness of formative assessments is poorly studied. All systems but 2 rely on a single method to assess performance. There is substantial potential to assess performance of doctors in routine practise. The longterm impact and effectiveness of formative performance assessments on education and quality of care remains hardly known. Future research designs need to pay special attention to unmasking effectiveness in terms of performance improvement.

Surgery for post-vitrectomy cataract

Background Cataract formation or acceleration can occur after intraocular surgery, especially following vitrectomy, a surgical technique for removing the vitreous which is used in the treatment of disorders that affect the posterior segment of the eye. The underlying problem that led to vitrectomy may limit the benefit from cataract surgery. Objectives The objective of this review was to evaluate the effectiveness and safety of surgery for post-vitrectomy cataract with respect to visual acuity, quality of life, and other outcomes. Search methods We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (The Cochrane Library 2013, Issue 4), Ovid MEDLINE, Ovid MEDLINE in-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily Update, Ovid OLDMED-LINE (January 1946 to May 2013), EMBASE (January 1980 to May 2013, Latin American and Caribbean Health Sciences Literature Database (LILACS) (January 1982 to May 2013), PubMed (January 1946 to May 2013), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com), ClinicalTrials.gov (www.clinicaltrial.gov) and the WHO International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 22 May 2013. Selection criteria We planned to include randomized and quasi-randomized controlled trials comparing cataract surgery with no surgery in adult patients who developed cataract following vitrectomy. Data collection and analysis Two authors screened the search results independently according to the standard methodological procedures expected by The Cochrane Collaboration. Main results We found no randomized or quasi-randomized controlled trials comparing cataract surgery with no cataract surgery for patients who developed cataracts following vitrectomy surgery. Authors' conclusions There is no evidence from randomized or quasi-randomized controlled trials on which to base clinical recommendations for surgery for post-vitrectomy cataract. There is a clear need for randomized controlled trials to address this evidence gap. Such trials should stratify participants by their age, the retinal disorder leading to vitrectomy, and the status of the underlying disease process in the contralateral eye. Outcomes assessed in such trials may include gain of vision on the Early Treatment Diabetic Retinopathy Study (ETDRS) scale, quality of life, and adverse events such as posterior capsular rupture. Both short-term (six-month) and long-term (one-year or two-year) outcomes should be examined. PMID:24357418

Short-acting insulin analogue use for people with diabetes is still controversial, as reflected in many scientific debates. To assess the effects of short-acting insulin analogues versus regular human insulin in adults with type 1 diabetes. We carried out the electronic searches through Ovid simultaneously searching the following databases: Ovid MEDLINE(R), Ovid MEDLINE(R) In-Process & Other Non-Indexed Citations, Ovid MEDLINE(R) Daily and Ovid OLDMEDLINE(R) (1946 to 14 April 2015), EMBASE (1988 to 2015, week 15), the Cochrane Central Register of Controlled Trials (CENTRAL; March 2015), ClinicalTrials.gov and the European (EU) Clinical Trials register (both March 2015). We included all randomised controlled trials with an intervention duration of at least 24 weeks that compared short-acting insulin analogues with regular human insulins in the treatment of adults with type 1 diabetes who were not pregnant. Two review authors independently extracted data and assessed trials for risk of bias, and resolved differences by consensus. We graded overall study quality using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) instrument. We used random-effects models for the main analyses and presented the results as odds ratios (OR) with 95% confidence intervals (CI) for dichotomous outcomes. We identified nine trials that fulfilled the inclusion criteria including 2693 participants. The duration of interventions ranged from 24 to 52 weeks with a mean of about 37 weeks. The participants showed some diversity, mainly with regard to diabetes duration and inclusion/exclusion criteria. The majority of the trials were carried out in the 1990s and participants were recruited from Europe, North America, Africa and Asia. None of the trials was carried out in a blinded manner so that the risk of performance bias, especially for subjective outcomes such as hypoglycaemia, was present in all of the trials. Furthermore, several trials showed inconsistencies in the reporting of methods and results.The mean difference (MD) in glycosylated haemoglobin A1c (HbA1c) was -0.15% (95% CI -0.2% to -0.1%; P value < 0.00001; 2608 participants; 9 trials; low quality evidence) in favour of insulin analogues. The comparison of the risk of severe hypoglycaemia between the two treatment groups showed an OR of 0.89 (95% CI 0.71 to 1.12; P value = 0.31; 2459 participants; 7 trials; very low quality evidence). For overall hypoglycaemia, also taking into account mild forms of hypoglycaemia, the data were generally of low quality, but also did not indicate substantial group differences. Regarding nocturnal severe hypoglycaemic episodes, two trials reported statistically significant effects in favour of the insulin analogue, insulin aspart. However, due to inconsistent reporting in publications and trial reports, the validity of the result remains questionable.We also found no clear evidence for a substantial effect of insulin analogues on health-related quality of life. However, there were few results only based on subgroups of the trial populations. None of the trials reported substantial effects regarding weight gain or any other adverse events. No trial was designed to investigate possible long-term effects (such as all-cause mortality, diabetic complications), in particular in people with diabetes related complications. Our analysis suggests only a minor benefit of short-acting insulin analogues on blood glucose control in people with type 1 diabetes. To make conclusions about the effect of short acting insulin analogues on long-term patient-relevant outcomes, long-term efficacy and safety data are needed.

A systematic review of the diagnostic performance of orthopedic physical examination tests of the hip

PubMed Central

2013-01-01

Background Previous reviews of the diagnostic performances of physical tests of the hip in orthopedics have drawn limited conclusions because of the low to moderate quality of primary studies published in the literature. This systematic review aims to build on these reviews by assessing a broad range of hip pathologies, and employing a more selective approach to the inclusion of studies in order to accurately gauge diagnostic performance for the purposes of making recommendations for clinical practice and future research. It specifically identifies tests which demonstrate strong and moderate diagnostic performance. Methods A systematic search of Medline, Embase, Embase Classic and CINAHL was conducted to identify studies of hip tests. Our selection criteria included an analysis of internal and external validity. We reported diagnostic performance in terms of sensitivity, specificity, predictive values and likelihood ratios. Likelihood ratios were used to identify tests with strong and moderate diagnostic utility. Results Only a small proportion of tests reported in the literature have been assessed in methodologically valid primary studies. 16 studies were included in our review, producing 56 independent test-pathology combinations. Two tests demonstrated strong clinical utility, the patellar-pubic percussion test for excluding radiologically occult hip fractures (negative LR 0.05, 95% Confidence Interval [CI] 0.03-0.08) and the hip abduction sign for diagnosing sarcoglycanopathies in patients with known muscular dystrophies (positive LR 34.29, 95% CI 10.97-122.30). Fifteen tests demonstrated moderate diagnostic utility for diagnosing and/or excluding hip fractures, symptomatic osteoarthritis and loosening of components post-total hip arthroplasty. Conclusions We have identified a number of tests demonstrating strong and moderate diagnostic performance. These findings must be viewed with caution as there are concerns over the methodological quality of the primary studies from which we have extracted our data. Future studies should recruit larger, representative populations and allow for the construction of complete 2×2 contingency tables. PMID:23987589

Estimating the burden of scrub typhus: A systematic review

PubMed Central

Bonell, Ana; Lubell, Yoel; Newton, Paul N.; Crump, John A.

2017-01-01

Background Scrub typhus is a vector-borne zoonotic disease that can be life-threatening. There are no licensed vaccines, or vector control efforts in place. Despite increasing awareness in endemic regions, the public health burden and global distribution of scrub typhus remains poorly known. Methods We systematically reviewed all literature from public health records, fever studies and reports available on the Ovid MEDLINE, Embase Classic + Embase and EconLit databases, to estimate the burden of scrub typhus since the year 2000. Findings In prospective fever studies from Asia, scrub typhus is a leading cause of treatable non-malarial febrile illness. Sero-epidemiological data also suggest that Orientia tsutsugamushi infection is common across Asia, with seroprevalence ranging from 9.3%–27.9% (median 22.2% IQR 18.6–25.7). A substantial apparent rise in minimum disease incidence (median 4.6/100,000/10 years, highest in China with 11.2/100,000/10 years) was reported through passive national surveillance systems in South Korea, Japan, China, and Thailand. Case fatality risks from areas of reduced drug-susceptibility are reported at 12.2% and 13.6% for South India and northern Thailand, respectively. Mortality reports vary widely around a median mortality of 6.0% for untreated and 1.4% for treated scrub typhus. Limited evidence suggests high mortality in complicated scrub typhus with CNS involvement (13.6% mortality), multi-organ dysfunction (24.1%) and high pregnancy miscarriage rates with poor neonatal outcomes. Interpretation Scrub typhus appears to be a truly neglected tropical disease mainly affecting rural populations, but increasingly also metropolitan areas. Rising minimum incidence rates have been reported over the past 8–10 years from countries with an established surveillance system. A wider distribution of scrub typhus beyond Asia is likely, based on reports from South America and Africa. Unfortunately, the quality and quantity of the available data on scrub typhus epidemiology is currently too limited for any economical, mathematical modeling or mapping approaches. PMID:28945755

The impact of user fees on access to health services in low- and middle-income countries.

PubMed

Lagarde, Mylene; Palmer, Natasha

2011-04-13

Following an international push for financing reforms, many low- and middle-income countries introduced user fees to raise additional revenue for health systems. User fees are charges levied at the point of use and are supposed to help reduce 'frivolous' consumption of health services, increase quality of services available and, as a result, increase utilisation of services. To assess the effectiveness of introducing, removing or changing user fees to improve access to care in low-and middle-income countries We searched 25 international databases, including the Cochrane Effective Practice and Organisation of Care (EPOC) Group's Trials Register, CENTRAL, MEDLINE and EMBASE. We also searched the websites and online resources of international agencies, organisations and universities to find relevant grey literature. We conducted the original searches between November 2005 and April 2006 and the updated search in CENTRAL (DVD-ROM 2011, Issue 1); MEDLINE In-Process & Other Non-Indexed Citations, Ovid (January 25, 2011); MEDLINE, Ovid (1948 to January Week 2 2011); EMBASE, Ovid (1980 to 2011 Week 03) and EconLit, CSA Illumina (1969 - present) on the 26th of January 2011. We included randomised controlled trials, interrupted time-series studies and controlled before-and-after studies that reported an objective measure of at least one of the following outcomes: healthcare utilisation, health expenditures, or health outcomes. We re-analysed studies with longitudinal data. We computed price elasticities of demand for health services in controlled before-and-after studies as a standardised measure. Due to the diversity of contexts and outcome measures, we did not perform meta-analysis. Instead, we undertook a narrative summary of evidence. We included 16 studies out of the 243 identified. Most of the included studies showed methodological weaknesses that hamper the strength and reliability of their findings. When fees were introduced or increased, we found the use of health services decreased significantly in most studies. Two studies found increases in health service use when quality improvements were introduced at the same time as user fees. However, these studies have a high risk of bias. We found no evidence of effects on health outcomes or health expenditure. The review suggests that reducing or removing user fees increases the utilisation of certain healthcare services. However, emerging evidence suggests that such a change may have unintended consequences on utilisation of preventive services and service quality. The review also found that introducing or increasing fees can have a negative impact on health services utilisation, although some evidence suggests that when implemented with quality improvements these interventions could be beneficial. Most of the included studies suffered from important methodological weaknesses. More rigorous research is needed to inform debates on the desirability and effects of user fees.

This article reports on a systematic review of articles on food labeling and the prevention of obesity and overweight, in the MEDLINE, EMBASE, Web of Knowledge, Cochrane Library Plus, Food Science and Technology Abstracts, LILACS, and CINAHL databases. The DeCS/MeSH descriptors were obesity and food labeling. 207 articles were retrieved. Using inclusion and exclusion criteria, 14 articles were selected: 11 were on food labeling and its impact on final food product consumption; 2 were on fast food establishments; 1 on sensory attributes as compared to health recommendations; and 2 on follow-up of interventions. Labeling has a positive effect on final food product consumption, in contrast with fast food restaurants. Sensory attributes were more effective than recommendations on the labels. Follow-up of interventions confirmed the long-term effect of the target interventions.

Obesity has been linked to an increased prevalence in multiple cancers. Studies have suggested a reduction in the overall risk of cancer after bariatric surgery. We reviewed the evidence for bariatric surgery reducing the risk of endometrial cancer. Data was extracted from PubMed, EMBASE, and Medline to perform a systematic review. Thirty-one full text articles were identified from 265 abstracts. Nine observational studies were relevant to endometrial cancer. In the five controlled studies, 462 of 113,032 (0.4%) patients receiving bariatric surgery versus 11,997 of 848,864 (1.4%) controls developed endometrial cancer, odds ratio of 0.317 (95% CI 0.161 to 0.627) using random effects model (P < 0.001). Bariatric surgery seems to reduce the risk of endometrial cancer; however, more research is required.

Cachexia and anorexia are among the most frequent symptoms in patients with cancer. Cannabinoids have been used in patients with advanced cancer; however, their role is still controversial. To answer this question we used Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, and generated a summary of findings table using the GRADE approach. We identified ten systematic reviews including three studies overall, of which two were randomized trials. We concluded it is not clear whether cannabinoids have any positive effect on increasing weight because the certainty of the evidence is very low. They might not have any effect on appetite, and are probably associated to frequent adverse effects.

In the medical community, bibliographic databases are widely accepted as a most important source of information both for theoretical and clinical disciplines. To improve access to medical bibliographic databases at Charles University, a database server (ERL by Silver Platter) was set up at the 2nd Faculty of Medicine in Prague. The server, accessible by Internet 24 hours/7 days, hosts now 14 years' MEDLINE and 10 years' EMBASE Paediatrics. Two different strategies are available for connecting to the server: a specialized client program that communicates over the Internet (suitable for professional searching) and a web-based access that requires no specialized software (except the WWW browser) on the client side. The server is now offered to academic community to host further databases, possibly subscribed by consortia whose individual members would not subscribe them by themselves.

Changing demographics mean that many patients with large joint arthritis will work beyond traditional retirement age. This review considers the impact of knee osteoarthritis (OA) on work participation and the relation between work and total knee replacement (TKR). Two systematic searches in Embase and Medline, supplemented by three systematic reviews. Probably, although evidence is limited, knee OA considerably impairs participation in work (labour force participation, work attendance and work productivity). AREAS OF UNCERTAINTY/RESEARCH NEED: Little is known about effective interventions (treatments, work changes and policies) to improve vocational participation in patients with knee OA; or how type of work affects long-term clinical outcomes (e.g. pain, function and the need for revision surgery) in patients with TKRs. The need for such research is pressing and opportune, as increasing numbers of patients with knee OA or TKR expect to work on.

Data on the association between using PDE5 inhibitors and malignant melanoma are conflicting. To estimate the relation of using PDE5 inhibitors with risk of malignant melanoma, Medline (Ovid) and Embase (Ovid) databases were searched up to February 2017, and a random effects model was used to calculate the summary risk estimates. Five observational studies were included. Five studies reports encompassed a total of 15,979 melanoma cases occurring among 1, 188,414 participants. The pooled multivariable-adjusted RR of melanoma in patients with using PDE5 inhibitors was 1.12 (95% CI: 1.03-1.21, I2 = 0.48). Findings from this systematic review support that PDE5 inhibitor use is associated with increased risk of melanoma in ED patients, the result remains inclusive and warrants further study in the future.

Effective leadership of healthcare professionals is critical for strengthening quality and integration of care. This study aimed to assess whether there exist an association between different leadership styles and healthcare quality measures. The search was performed in the Medline (National Library of Medicine, PubMed interface) and EMBASE databases for the time period 2004–2015. The research question that guided this review was posed as: “Is there any relationship between leadership style in healthcare settings and quality of care?” Eighteen articles were found relevant to our research question. Leadership styles were found to be strongly correlated with quality care and associated measures. Leadership was considered a core element for a well-coordinated and integrated provision of care, both from the patients and healthcare professionals. PMID:29036901

Quality anesthesia during surgery and in the postoperative period remains a topical problem of modern anesthesiology. The study of genetic characteristics of a patient is a goal that may be allow us to develop a personalized approach to solve this problem. The purpose of the review is a synthesis of literature data about the influence of genetic factors on pain perception and its treatment. The review included information obtained from SCOPUS, MedLine, EMBASE. The search keywords were: pain, pharmacogenetics, polymorphism, analgesics.Describe the effect ofgene polymorphisms of OPRM, 5HTRIA, 5HTR2A, COMT GCHI, SCN9A, KCNSI, CACNA2D3, CACNG2, PTGSI, PTGS2, MDRJ/ABCB] on the perception of pain, and CYP2D6, CYP2C9, CYP3A4 on the pharmacokinetics and pharmacodynamics of medi- cations used in the treatment of pain.

Generalized anxiety disorder prevalence and comorbidity with depression in coronary heart disease patients remain unquantified. Systematic searching of Medline, Embase, SCOPUS and PsycINFO databases revealed 1025 unique citations. Aggregate generalized anxiety disorder prevalence (12 studies, N = 3485) was 10.94 per cent (95% confidence interval: 7.8-13.99) and 13.52 per cent (95% confidence interval: 8.39-18.66) employing Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria (random effects). Lifetime generalized anxiety disorder prevalence was 25.80 per cent (95% confidence interval: 20.84-30.77). In seven studies, modest correlation was evident between generalized anxiety disorder and depression, Fisher's Z = .30 (95% confidence interval: .19-.42), suggesting that each psychiatric disorder is best conceptualized as contributing unique variance to coronary heart disease prognosis.

Rollover crashes (ROCs) are responsible for almost a third of all highway vehicle occupant fatalities. Although ROCs are common and serious mechanism of injury, ROCs are under-reported. To analyze the causes, mechanism, impact and prevention of ROCs, we reviewed the literature between 1984 and 2013. By utilizing the search engines PubMed, MEDLINE and EMBASE by using key words “ROCs” “Ejection” and “vehicle” the initial search yielded 241 abstracts, of which 58 articles were relevant. Most of the articles were either retrospective or experimental studies funded by automobile companies. All vehicles are susceptible to rollovers to certain extents. Despite continuing innovation in vehicles’ safety, human factor is pivotal in prevention of ROCs. Distracted driving, speeding and drinking escalate the chances of rollover crashes. Wearing a seatbelt greatly improves the chances of surviving a ROC. PMID:25221693

This best practice review examines four series of common primary care questions in laboratory medicine: (i) “minor” blood platelet count and haemoglobin abnormalities; (ii) diagnosis and monitoring of anaemia caused by iron deficiency; (iii) secondary hyperlipidaemia and hypertriglyceridaemia; and (iv) glycated haemoglobin and microalbumin use in diabetes. The review is presented in question–answer format, referenced for each question series. The recommendations represent a précis of guidance found using a standardised literature search of national and international guidance notes, consensus statements, health policy documents and evidence‐based medicine reviews, supplemented by Medline Embase searches to identify relevant primary research documents. They are not standards, but form a guide to be set in the clinical context. Most of the recommendations are based on consensus rather than evidence. They will be updated periodically to take account of new information. PMID:16873560

Cancer-related pain is complex and multi-dimensional but the mainstay of cancer pain management has predominantly used a biomedical approach. There is a need for non-pharmacological and innovative approaches. Transcutaneous Electric Nerve Stimulation (TENS) may have a role in pain management but the effectiveness of TENS is currently unknown. This is an update of the original review published in Issue 3, 2008. The aim of this systematic review was to determine the effectiveness of TENS for cancer-related pain in adults. The initial review searched The Cochrane Library, MEDLINE, EMBASE, CINAHL, PsychINFO, AMED and PEDRO databases in April 2008. We performed an updated search of CENTRAL, MEDLINE, EMBASE, CINAHL and PEDRO databases in November 2011. We included only randomised controlled trials (RCTS) investigating the use of TENS for the management of cancer-related pain in adults. The search strategy identified a further two studies for possible inclusion. One of the review authors screened each abstract using a study eligibility tool. Where eligibility could not be determined, a second author assessed the full paper. One author used a standardised data extraction sheet to collect information on the studies and independently assess the quality of the studies using the validated five-point Oxford Quality Scale. The small sample sizes and differences in patient study populations of the three included studies (two from the original review and a third included in this update) prevented meta-analysis. For the original review the search strategy identified 37 possible published studies; we divided these between two pairs of review authors who decided on study selection; all four review authors discussed and agreed final scores. Only one additional RCT met the eligibility criteria (24 participants) for this updated review. Although this was a feasibility study, not designed to investigate intervention effect, it suggested that TENS may improve bone pain on movement in a cancer population. The initial review identified two RCTs (64 participants) therefore this review now includes a total of three RCTs (88 participants). These studies were heterogenous with respect to study population, sample size, study design, methodological quality, mode of TENS, treatment duration, method of administration and outcome measures used. In one RCT, there were no significant differences between TENS and placebo in women with chronic pain secondary to breast cancer treatment. In the other RCT, there were no significant differences between acupuncture-type TENS and sham in palliative care patients; this study was underpowered. Despite the one additional RCT, the results of this updated systematic review remain inconclusive due to a lack of suitable RCTs. Large multi-centre RCTs are required to assess the value of TENS in the management of cancer-related pain in adults.

Publications on dementia in Medline 1974-2009: a quantitative bibliometric study.

2013-05-01

The aim is to describe the development of the scientific literature on dementia. We present a quantitative, bibliometric study of the literature on dementia, based on Medline, covering 36 years (1974-2009). Two samples of references to dementia papers were retrieved: The main sample based on the MeSH term Dementia holds more than 88,500 references. We have compared the annual additions of references on dementia with the addition to total Medline. Changes of 'the Dementia to Medline ratio' (%) give the best information on the development. Publications on dementia increased 5.6 times faster than Medline. Most of this relative acceleration took place during 1980-1997, when the references on dementia increased from 0.17 to 0.78%. During the recent 12 years, the publications on dementia have been keeping pace with Medline and have stabilized around 0.8%. We have shown a large increase of the literature on dementia, relative both to the development of all medical research and to all psychiatric research. The bibliometric approach may be questioned as quantitative methods treat articles as being of equal value, what is not true. If, for example, during a certain period, the research output is 'inflated' by a great number of repetitive papers, the quantitative method will give an unfair picture of the development. Our relative method, however, will give relevant results as, at each point of time, the proportion of 'valuable research' ought to be about the same in the dementia group as in total Medline.

Objectives There is a growing body of literature on malaria forecasting methods and the objective of our review is to identify and assess methods, including predictors, used to forecast malaria. Design Scoping review. Two independent reviewers searched information sources, assessed studies for inclusion and extracted data from each study. Information sources Search strategies were developed and the following databases were searched: CAB Abstracts, EMBASE, Global Health, MEDLINE, ProQuest Dissertations & Theses and Web of Science. Key journals and websites were also manually searched. Eligibility criteria for included studies We included studies that forecasted incidence, prevalence or epidemics of malaria over time. A description of the forecasting model and an assessment of the forecast accuracy of the model were requirements for inclusion. Studies were restricted to human populations and to autochthonous transmission settings. Results We identified 29 different studies that met our inclusion criteria for this review. The forecasting approaches included statistical modelling, mathematical modelling and machine learning methods. Climate-related predictors were used consistently in forecasting models, with the most common predictors being rainfall, relative humidity, temperature and the normalised difference vegetation index. Model evaluation was typically based on a reserved portion of data and accuracy was measured in a variety of ways including mean-squared error and correlation coefficients. We could not compare the forecast accuracy of models from the different studies as the evaluation measures differed across the studies. Conclusions Applying different forecasting methods to the same data, exploring the predictive ability of non-environmental variables, including transmission reducing interventions and using common forecast accuracy measures will allow malaria researchers to compare and improve models and methods, which should improve the quality of malaria forecasting.

UK primary care databases are frequently used in observational studies with cancer outcomes. We aimed to systematically review methods used by such studies to identify and validate incident cancers of the breast, colorectum, and prostate. Medline and Embase (1980-2013) were searched for UK primary care database studies with incident breast, colorectal, or prostate cancer outcomes. Data on the methods used for case ascertainment were extracted and summarised. Questionnaires were sent to corresponding authors to obtain details about case ascertainment. Eighty-four studies of breast (n = 51), colorectal (n = 54), and prostate cancer (n = 31) were identified; 30 examined >1 cancer type. Among the 84 studies, 57 defined cancers using only diagnosis codes, while 27 required further evidence such as chemotherapy. Few studies described methods used to create cancer code lists (n = 5); or made lists available directly (n = 5). Twenty-eight code lists were received on request from study authors. All included malignant neoplasm diagnosis codes, but there was considerable variation in the specific codes included which was not explained by coding dictionary changes. Code lists also varied in terms of other types of codes included, such as in-situ, cancer morphology, history of cancer, and secondary/suspected/borderline cancer codes. In UK primary care database studies, methods for identifying breast, colorectal, and prostate cancers were often unclear. Code lists were often unavailable, and where provided, we observed variation in the individual codes and types of codes included. Clearer reporting of methods and publication of code lists would improve transparency and reproducibility of studies. Copyright © 2014 John Wiley & Sons, Ltd.

2017-01-01

To review the current literature regarding methods and effects of real-time biofeedback used as a method for gait retraining to reduce knee adduction moment (KAM), with intended application for patients with knee osteoarthritis (KOA). Searches were conducted in MEDLINE, Embase, CINAHL, SPORTDiscus, Web of Science, and Cochrane Central Register of Controlled Trials with the keywords gait, feedback, and knee osteoarthritis from inception to May 2015. Titles and abstracts were screened by 1 individual for studies aiming to reduce KAM. Full-text articles were assessed by 2 individuals against predefined criteria. Data were extracted by 1 individual according to a predefined list, including participant demographics and training methods and effects. Electronic searches resulted in 190 potentially eligible studies, from which 12 met all inclusion criteria. Within-group standardized mean differences (SMDs) for reduction of KAM in healthy controls ranged from .44 to 2.47 and from .29 to .37 in patients with KOA. In patients with KOA, improvements were reported in pain and function, with SMDs ranging from .55 to 1.16. Methods of implementation of biofeedback training varied between studies, but in healthy controls increased KAM reduction was noted with implicit, rather than explicit, instructions. This review suggests that biofeedback gait training is effective primarily for reducing KAM but also for reducing pain and improving function in patients with KOA. The review was limited by the small number of studies featuring patients with KOA and the lack of controlled studies. The results suggest there is value and a need in further researching biofeedback training for reducing KAM. Future studies should include larger cohorts of patients, long-term follow-up, and controlled trials. Copyright © 2016 American Congress of Rehabilitation Medicine. Published by Elsevier Inc.

The Determinants of Place of Death: An Evidence-Based Analysis

PubMed Central

Costa, V

2014-01-01

Background According to a conceptual model described in this analysis, place of death is determined by an interplay of factors associated with the illness, the individual, and the environment. Objectives Our objective was to evaluate the determinants of place of death for adult patients who have been diagnosed with an advanced, life-limiting condition and are not expected to stabilize or improve. Data Sources A literature search was performed using Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid Embase, EBSCO Cumulative Index to Nursing & Allied Health Literature (CINAHL), and EBM Reviews, for studies published from January 1, 2004, to September 24, 2013. Review Methods Different places of death are considered in this analysis—home, nursing home, inpatient hospice, and inpatient palliative care unit, compared with hospital. We selected factors to evaluate from a list of possible predictors—i.e., determinants—of death. We extracted the adjusted odds ratios and 95% confidence intervals of each determinant, performed a meta-analysis if appropriate, and conducted a stratified analysis if substantial heterogeneity was observed. Results From a literature search yielding 5,899 citations, we included 2 systematic reviews and 29 observational studies. Factors that increased the likelihood of home death included multidisciplinary home palliative care, patient preference, having an informal caregiver, and the caregiver's ability to cope. Factors increasing the likelihood of a nursing home death included the availability of palliative care in the nursing home and the existence of advance directives. A cancer diagnosis and the involvement of home care services increased the likelihood of dying in an inpatient palliative care unit. A cancer diagnosis and a longer time between referral to palliative care and death increased the likelihood of inpatient hospice death. The quality of the evidence was considered low. Limitations Our results are based on those of retrospective observational studies. Conclusions The results obtained were consistent with previously published systematic reviews. The analysis identified several factors that are associated with place of death. PMID:26351550

Background. The use of natural health products in prostate cancer (PrCa) is high despite a lack of evidence with respect to safety and efficacy. Fish-derived omega-3 fatty acids possess anti-inflammatory effects and preclinical data suggest a protective effect on PrCa incidence and progression; however, human studies have yielded conflicting results. Methods. A search of OVID MEDLINE, Pre-MEDLINE, Embase, and the Allied and Complementary Medicine Database (AMED) was completed for human interventional or observational data assessing the safety and efficacy of fish-derived omega-3 fatty acids in the incidence and progression of PrCa. Results. Of 1776 citations screened, 54 publications reporting on 44 studies were included for review and analysis: 4 reports of 3 randomized controlled trials, 1 nonrandomized clinical trial, 20 reports of 14 cohort studies, 26 reports of 23 case-control studies, and 3 case-cohort studies. The interventional studies using fish oil supplements in patients with PrCa showed no impact on prostate-specific antigen levels; however, 2 studies showed a decrease in inflammatory or other cancer markers. A small number of mild adverse events were reported and interactions with other interventions were not assessed. Cohort and case-control studies assessing the relationship between dietary fish intake and the risk of PrCa were equivocal. Cohort studies assessing the risk of PrCa mortality suggested an association between higher intake of fish and decreased risk of prostate cancer–related death. Conclusions. Current evidence is insufficient to suggest a relationship between fish-derived omega-3 fatty acid and risk of PrCa. An association between higher omega-3 intake and decreased PrCa mortality may be present but more research is needed. More intervention trials or observational studies with precisely measured exposure are needed to assess the impact of fish oil supplements and dietary fish-derived omega-3 fatty acid intake on safety, PrCa incidence, treatment, and progression.

Objective The decline in available oestrogen after menopause is a possible etiological factor in pelvic floor disorders like vaginal atrophy (VA), urinary incontinence (UI), overactive bladder (OAB) and pelvic organ prolapse (POP). This systematic review will examine the evidence for local oestrogen therapy in the treatment of these pelvic floor disorders. Evidence Acquisition We performed a systematic search in MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials and the non-MEDLINE subset of PubMed from inception to May 2014. We searched for local oestrogens and VA (I), UI/OAB (II) and POP (III). Part I was combined with broad methodological filters for randomized controlled trials (RCTs) and secondary evidence. For part I and II two reviewers independently selected RCTs evaluating the effect of topical oestrogens on symptoms and signs of VA and UI/OAB. In part III all studies of topical oestrogen therapy in the treatment of POP were selected. Data extraction and the assessment of risk of bias using the Cochrane Risk of Bias Tool was undertaken independently by two reviewers. Evidence Synthesis The included studies varied in ways of topical application, types of oestrogen, dosage and treatment durations. Objective and subjective outcomes were assessed by a variety of measures. Overall, subjective and urodynamic outcomes, vaginal maturation and vaginal pH changed in favor of vaginal oestrogens compared to placebo. No obvious differences between different application methods were revealed. Low doses already seemed to have a beneficial effect. Studies evaluating the effect of topical oestrogen in women with POP are scarce and mainly assessed symptoms and signs associated with VA instead of POP symptoms. Conclusion Topical oestrogen administration is effective for the treatment of VA and seems to decrease complaints of OAB and UI. The potential for local oestrogens in the prevention as well as treatment of POP needs further research. PMID:26383760

“Many miles to go …”: a systematic review of the implementation of patient decision support interventions into routine clinical practice

PubMed Central

2013-01-01

Background Two decades of research has established the positive effect of using patient-targeted decision support interventions: patients gain knowledge, greater understanding of probabilities and increased confidence in decisions. Yet, despite their efficacy, the effectiveness of these decision support interventions in routine practice has yet to be established; widespread adoption has not occurred. The aim of this review was to search for and analyze the findings of published peer-reviewed studies that investigated the success levels of strategies or methods where attempts were made to implement patient-targeted decision support interventions into routine clinical settings. Methods An electronic search strategy was devised and adapted for the following databases: ASSIA, CINAHL, Embase, HMIC, Medline, Medline-in-process, OpenSIGLE, PsycINFO, Scopus, Social Services Abstracts, and the Web of Science. In addition, we used snowballing techniques. Studies were included after dual independent assessment. Results After assessment, 5322 abstracts yielded 51 articles for consideration. After examining full-texts, 17 studies were included and subjected to data extraction. The approach used in all studies was one where clinicians and their staff used a referral model, asking eligible patients to use decision support. The results point to significant challenges to the implementation of patient decision support using this model, including indifference on the part of health care professionals. This indifference stemmed from a reported lack of confidence in the content of decision support interventions and concern about disruption to established workflows, ultimately contributing to organizational inertia regarding their adoption. Conclusions It seems too early to make firm recommendations about how best to implement patient decision support into routine practice because approaches that use a ‘referral model’ consistently report difficulties. We sense that the underlying issues that militate against the use of patient decision support and, more generally, limit the adoption of shared decision making, are under-investigated and under-specified. Future reports from implementation studies could be improved by following guidelines, for example the SQUIRE proposals, and by adopting methods that would be able to go beyond the ‘barriers’ and ‘facilitators’ approach to understand more about the nature of professional and organizational resistance to these tools. The lack of incentives that reward the use of these interventions needs to be considered as a significant impediment. PMID:24625083

Context Inflammation after spinal cord injury (SCI) may be responsible for further neural damages and therefore inhibition of inflammatory processes may exert a neuroprotection effect. Objectives To assess the efficacy of some non-conventional herbal medications including sulforaphane, tanshinone IIA, and tetramethylpyrazine in reducing inflammation and compare them with a known effective anti-inflammatory agent (interleukin-10 (IL-10)). Methods We searched relevant articles in Ovid database, Medline (PubMed) EMBASE, Google Scholar, Cochrane, and Scopus up to June 2013. The efficacy of each treatment and study powers were compared using random effects model of meta-analysis. To our knowledge, no conflict of interest exists. Results Eighteen articles entered into the study. The meta-analysis revealed that exogenous IL-10 was more effective in comparison with the mentioned herbal extracts. The proposed pathways for each medication's effect on reducing the inflammation process are complex and many overlaps may exist. Conclusion IL-10 has a strong effect in the induction of neuroprotection and neurorecovery after SCI by multiple pathways. Tetramethylpyrazine has an acceptable influence in reducing inflammation through the up-regulation of IL-10. Outcomes of sulforaphane and tanshinone IIA administration are acceptable but still weaker than IL-10. PMID:24969510

Chinese Herbal Medicine and Depression: The Research Evidence

PubMed Central

Butler, Lee; Pilkington, Karen

2013-01-01

Background. Alternative approaches for managing depression are often sought and herbal mixtures are widely used in China. The aim of this paper was to provide an overall picture of the current evidence by analysing published systematic reviews and presenting a supplementary systematic review of trials in Western databases. Methods. Searches were conducted using AMED, Cochrane Library, EMBASE, MEDLINE/PubMed, PsycINFO, and trial registers. Results were screened and selected trials were evaluated by two reviewers working independently. Systematic reviews were identified and assessed using key criteria. Results. Five systematic reviews were located addressing the Chinese literature, adjunctive use of Chinese herbs, and the formulae Chaihu-Shugan-San, Xiao Yao San, and Free and Easy Wanderer Plus. The supplementary review located 8 trials, 3 of which were not included in previous reviews. Positive results were reported: no significant differences from medication, greater effect than medication or placebo, reduced adverse event rates when combined or compared with antidepressants. However, limitations in methodology and reporting were revealed. Conclusions. Despite promising results, particularly for Xiao Yao San and its modifications, the effectiveness of Chinese herbal medicine in depression could not be fully substantiated based on current evidence. Further well-designed, well-reported trials that reflect practice may be worth pursuing. PMID:23476701

Effective intervention or child's play? A review of video games for diabetes education.

The purpose of this study is (1) to identify diabetes education video games and pilot studies in the literature, (2) to review themes in diabetes video game design and evaluation, and (3) to evaluate the potential role of educational video games in diabetes self-management education. Studies were systematically identified for inclusion from Medline, Web of Science, CINAHL, EMBASE, Psychinfo, IEEE Xplore, and ACM Digital Library. Features of each video game intervention were reviewed and coded based on an existing taxonomy of diabetes interventions framework. Nine studies featuring 11 video games for diabetes care were identified. Video games for diabetes have typically targeted children with type 1 diabetes mellitus and used situation problem-solving methods to teach diet, exercise, self-monitored blood glucose, and medication adherence. Evaluations have shown positive outcomes in knowledge, disease management adherence, and clinical outcomes. Video games for diabetes education show potential as effective educational interventions. Yet we found that improvements are needed in expanding the target audience, tailoring the intervention, and using theoretical frameworks. In the future, the reach and effectiveness of educational video games for diabetes education could be improved by expanding the target audience beyond juvenile type 1 diabetes mellitus, the use of tailoring, and increased use of theoretical frameworks.

The risk of elevated prolactin levels in pediatric patients exposed to antipsychotics for the treatment of schizophrenia and schizophrenia spectrum disorders: protocol for a systematic review and meta-analysis

PubMed Central

2014-01-01

Background Antipsychotic medications, particularly second-generation antipsychotics, are increasingly being used to alleviate the symptoms of schizophrenia and other severe mental disorders in the pediatric population. While evidence-based approaches examining efficacy and safety outcomes have been reported, no review has evaluated prolactin-based adverse events for antipsychotic treatments in schizophrenia and schizophrenia spectrum disorders. Methods/design Searches involving MEDLINE, EMBASE, CENTRAL, PsycINFO, and clinical trial registries (ClinicalTrials.gov, Drug Industry Document Archive [DIDA], International Clinical Trials Registry Platform [ICTRP]) will be used to identify relevant studies. Two reviewers will independently screen abstracts and relevant full-text articles of the papers identified by the initial search according to the prospectively defined eligibility criteria. Data extraction will be conducted in duplicate independently. Pairwise random effects meta-analyses and network meta-analyses will be conducted on individual drug and class effects where appropriate. Discussion This systematic review will evaluate prolactin-based adverse events of first- and second-generation antipsychotics in the pediatric population with schizophrenia and schizophrenia spectrum disorders. It will also seek to strengthen the evidence base of the safety of antipsychotics by incorporating both randomized controlled trials and observational studies.

Wardle, Jane; Wolf, Michael S.; von Wagner, Christian

2016-01-01

Objectives: To review the evidence on the association between age and limited health literacy, overall and by health literacy test, and to investigate the mediating role of cognitive function. Method: The Embase, MEDLINE, and PsycINFO databases were searched. Eligible studies were conducted in any country or language, included participants aged ≥50 years, presented a measure of association between age and health literacy, and were published through September 2013. Results: Seventy analyses in 60 studies were included in the systematic review; 29 of these were included in the meta-analysis. Older age was strongly associated with limited health literacy in analyses that measured health literacy as reading comprehension, reasoning, and numeracy skills (random-effects odds ratio [OR] = 4.20; 95% confidence interval [CI]: 3.13–5.64). By contrast, older age was weakly associated with limited health literacy in studies that measured health literacy as medical vocabulary (random-effects OR = 1.19; 95% CI: 1.03–1.37). Evidence on the mediating role of cognitive function was limited. Discussion: Health literacy tests that utilize a range of fluid cognitive abilities and mirror everyday health tasks frequently observe skill limitations among older adults. Vocabulary-based health literacy skills appear more stable with age. Researchers should select measurement tests wisely when assessing health literacy of older adults. PMID:25504637

To investigate ethnic difference by focusing on fasting serum insulin (FSI) in inter-East Asian patients with type 2 diabetes. Data sources included MEDLINE and EMBASE between 2001 and 2006. We conducted a search for articles containing mean or geometric mean values of FSI in East Asian patients with type 2 diabetes. The Monte Carlo method was used for simulation of the mean and standard deviation of individual measures in each ethnic group; calculation of the median ratio and 95% confidence interval of individual measures between ethnic groups. The initial search identified a total of 996 journal articles. After reviewing the titles and abstracts of these articles, 201 studies were selected for further screening and the complete papers on these studies were then reviewed in detail. Of these, seven articles fully met our pre-determined criteria and were included in the meta-analysis. Results of the meta-analysis revealed that FSI level is significantly lower in Japanese patients than in Korean and Chinese patients. Results from our review of ethnic differences in dietary habit in the inter-East Asian population suggested that difference in dietary component was one of the most influential factors for the ethnic difference.

2015-01-01

Background. Cognitive interventions for older persons that may diminish the burden of cognitive problems and could delay conversion to dementia are of great importance. The underlying mechanisms of such interventions might be psychological compensation and neuronal plasticity. This review provides an overview of the literature concerning the evidence that cognitive interventions cause brain activation changes, even in damaged neural systems. Method. A systematic search of the literature was conducted in several international databases, Medline, Embase, Cinahl, Cochrane, and Psychinfo. The methodological quality was assessed according to the guidelines of the Dutch Institute for Health Care Improvement (CBO). Results. Nineteen relevant articles were included with varied methodological quality. All studies were conducted in diverse populations from healthy elderly to patients with dementia and show changes in brain activation after intervention. Conclusions. The results thus far show that cognitive interventions cause changes in brain activation patterns. The exact interpretation of these neurobiological changes remains unclear. More study is needed to understand the extent to which cognitive interventions are effective to delay conversion to dementia. Future studies should more explicitly try to relate clinically significant improvement to changes in brain activation. Long-term follow-up data are necessary to evaluate the stability of the effects.

Physician dual practice is a common phenomenon in almost all countries throughout the world, which could potential impacts on access, equity and quality of services. This paper aims to review studies in physician dual practice and categorize them in order to their main objectives and purposes. Comprehensive literature searches were undertaken in order to obtain main papers and documents in the field of physician dual practice. Systematic searches in Medline and Embase from 1960 to 2013, and general searches in some popular search engines were carried out in this way. After that, descriptive mapping review methods were utilized to categorize eligible studies in this area. The searches obtained 404 titles, of which 81 full texts were assessed. Finally, 24 studies were eligible for inclusion in our review. These studies were categorized into four groups - "motivation and forces behind dual practice", "consequences of dual practice", "dual practice Policies and their impacts", and "other studies" - based on their main objectives. Our findings showed a dearth of scientifically reliable literature in some areas of dual practice, like the prevalence of the phenomenon, the real consequences of it, and the impacts of the implemented policy measures. Rigorous empirical and evaluative studies should be designed to detect the real consequences of DP and assess the effects of interventions and regulations, which governments have implemented in this field.

Objectives. To identify the virtual reality (VR) interventions used for the lower extremity rehabilitation in stroke population and to explain their underlying training mechanisms using Social Cognitive (SCT) and Motor Learning (MLT) theoretical frameworks. Methods. Medline, Embase, Cinahl, and Cochrane databases were searched up to July 11, 2013. Randomized controlled trials that included a VR intervention for lower extremity rehabilitation in stroke population were included. The Physiotherapy Evidence Database (PEDro) scale was used to assess the quality of the included studies. The underlying training mechanisms involved in each VR intervention were explained according to the principles of SCT (vicarious learning, performance accomplishment, and verbal persuasion) and MLT (focus of attention, order and predictability of practice, augmented feedback, and feedback fading). Results. Eleven studies were included. PEDro scores varied from 3 to 7/10. All studies but one showed significant improvement in outcomes in favour of the VR group (P < 0.05). Ten VR interventions followed the principle of performance accomplishment. All the eleven VR interventions directed subject's attention externally, whereas nine provided training in an unpredictable and variable fashion. Conclusions. The results of this review suggest that VR applications used for lower extremity rehabilitation in stroke population predominantly mediate learning through providing a task-oriented and graduated learning under a variable and unpredictable practice.

Madsen, Michael T.; Rosenberg, Jacob; Gögenur, Ismail

2013-01-01

Study Objectives: Patients undergoing surgery have severe sleep and sleep-wake rhythm disturbances resulting in increased morbidity. Actigraphy is a tool that can be used to quantify these disturbances. The aim of this manuscript was to present the literature where actigraphy has been used to measure sleep and sleep-wake rhythms in relation to surgery. Methods: A systematic review was performed in 3 databases (Medline, Embase, and Psycinfo), including all literature until July 2012. Results: Thirty-two studies were included in the review. Actigraphy could demonstrate that total sleep time and sleep efficiency was reduced after surgery and number of awakenings was increased in patients undergoing major surgery. Disturbances were less severe in patients undergoing minor surgery. Actigraphy could be used to differentiate between delirious and non-delirious patients after major surgery. Actigraphy measurements could determine a differential effect of surgery based on the patient's age. The effect of pharmacological interventions (chronobiotics and hypnotics) in surgical patients could also be demonstrated by actigraphy. Conclusion: Actigraphy can be used to measure sleep and sleep-wake rhythms in patients undergoing surgery. Citation: Madsen MT; Rosenberg J; Gögenur I.

Introduction The aim is to update and disclose the main environmental risk factors, excluding dietary factors, involved in the etiopathology of prostate cancer. Materials and methods Bibliographic review of the last 25 years of non-dietary environmental risk factors associated with prostate cancer between 1985 and 2010, obtained from MedLine, CancerLit, Science Citation Index and Embase. The search profiles were Environmental Risk Factors/Tobacco/Infectious-Inflammatory Factors/Pesticides/Vasectomy/Occupational Exposures/ Chemoprevention Agents/Radiation and Prostate Cancer. Results While some non-dietary environmental risk factors increase the risk of acquiring the disease, others decrease it. Of the former, it is worth mentioning exposal to tobacco smoke, chronic infectious-inflammatory prostatic processes and occupational exposure to cadmium, herbicides and pesticides. The first factors that reduce the risk are the use of chemopreventive drugs (Finasterida, Dutasteride) and exposure to ultraviolet solar radiation. With the current data, a vasectomy does not influence the risk of developing the disease. Conclusions The slow process of prostate carcinogenesis is the final result of the interaction of constitutional risk and environmental factors. Non-dietary environmental factors play an important role in the etiopathology of this disease. To appropriately assess the risk factors, extensive case studies that include all the possible variables must be analyzed. PMID:21439685

To review the literature on perceptions of nursing students and/or educators on the contribution of ethics education to ethical competence in nursing students. Nurses do not always demonstrate the competencies necessary to engage in ethical practice. Educators continue to debate about the best ways to teach ethics to nurses so that they can develop ethical competencies. MEDLINE, Embase, CINAHL, PsycINFO, and Web of Science. A total of 15 articles with a quantitative, qualitative, or mixed-methods design published between January 1992 and March 2012 were analyzed. According to students and educators, ethics education increases ethical perception of nursing students and the development of reflective and analytical skills. However, its contribution to the development of ethical behavior was barely mentioned. The accounts of students and educators revealed essential features of effective ethics education: active involvement of students in case study discussions and use of ethical frameworks. The use of activating educational strategies requires a safe learning environment where students can openly reflect on values at stake in their care practice. A better understanding of how students learn to develop ethical skills and of influencing factors can guide educators to develop ethics courses for nursing curriculum. Future research needs to focus on the methodological accuracy of sampling and measuring instruments. © The Author(s) 2014.

Menopause may be a time of increased mood symptoms for some women. This systematic review aimed to examine the severity of symptoms and prevalence of mood changes in women with bipolar disorder during peri-menopause and post-menopause. A systematic review was undertaken in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The two primary outcomes assessed were relapse rates and symptom severity during menopause. Databases searched were MEDLINE, EMBASE, PsychInfo, CINAHL and SCOPUS from January 1980 until December 2016. Nine studies, including a total of 273 participants diagnosed with bipolar disorder and who reported menopause, were included in the narrative synthesis. Menopause was reported to be associated with increased symptoms overall, and with depression in particular (range of 46%-91%). The collection of self-reported retrospective data was the most commonly used method to record menopause status. The impact of menopause on illness course for women with bipolar disorder is largely under-explored. Preliminary evidence suggests that it may be associated with increased bipolar symptoms. Further work is needed to explore how menopause may interact with bipolar disorder over time and the nature of these symptom changes, and if and how menopause may differ from other reproductive stages. © 2017 John Wiley & Sons A/S.

Objectives This study aimed to identify and systematically review the literature on the use of mobile technology in nursing education. The research findings could evidence the effectiveness of mobile technology in undergraduate nursing students' learning outcomes. Methods Computerized searches were conducted using the Ovid-MEDLINE, Ovid-EMBASE, Cochrane Library, and CINAHL databases for relevant primary studies and limited to those between 2000 and February 2018. Only randomized controlled trials (RCTs) and quasi-experimental studies published in either English or Korean were included and critically appraised using Joanna Briggs Institute tools. Results Seven RCTs and 7 quasi-experimental studies were identified. The mobile device and intervention applied varied throughout all the studies. Studies published earlier in the 2000s found that immediate access to clinical and pharmacological referencing information through the mobile device increased students' efficacy in clinical practice. Later studies, which were mostly conducted in Korea, reported that smartphone-based applications could promote nursing students' learning motivation and satisfaction but not their clinical skills and knowledge. Conclusions We still seem to be in the beginning stage of implementing mobile technology in nursing education due to the limited implication of mobile technology and inconsistent research conclusions. In the future, rigorous primary empirical studies are needed to suggest the effective use of mobile devices in nursing education. PMID:29770243

Background Public sector austerity measures in many high-income countries mean that public health budgets are reducing year on year. To help inform the potential impact of these proposed disinvestments in public health, we set out to determine the return on investment (ROI) from a range of existing public health interventions. Methods We conducted systematic searches on all relevant databases (including MEDLINE; EMBASE; CINAHL; AMED; PubMed, Cochrane and Scopus) to identify studies that calculated a ROI or cost-benefit ratio (CBR) for public health interventions in high-income countries. Results We identified 2957 titles, and included 52 studies. The median ROI for public health interventions was 14.3 to 1, and median CBR was 8.3. The median ROI for all 29 local public health interventions was 4.1 to 1, and median CBR was 10.3. Even larger benefits were reported in 28 studies analysing nationwide public health interventions; the median ROI was 27.2, and median CBR was 17.5. Conclusions This systematic review suggests that local and national public health interventions are highly cost-saving. Cuts to public health budgets in high income countries therefore represent a false economy, and are likely to generate billions of pounds of additional costs to health services and the wider economy.

Background Management of rhinosinusitis during pregnancy requires special considerations. Objectives 1. Conduct a systematic literature review for acute and chronic rhinosinusitis (CRS) management during pregnancy. 2. Make evidence-based recommendations. Methods The systematic review was conducted using MEDLINE and EMBASE databases and relevant search terms. Title, abstract and full manuscript review were conducted by two authors independently. A multispecialty panel with expertise in management of Rhinological disorders, Allergy-Immunology, and Obstetrics-Gynecology was invited to review the systematic review. Recommendations were sought on use of following for CRS management during pregnancy: oral corticosteroids; antibiotics; leukotrienes; topical corticosteroid spray/irrigations/drops; aspirin desensitization; elective surgery for CRS with polyps prior to planned pregnancy; vaginal birth versus planned Caesarian for skull base erosions/ prior CSF rhinorrhea. Results Eighty-eight manuscripts underwent full review after screening 3052 abstracts. No relevant level 1, 2, or 3 studies were found. Expert panel recommendations for rhinosinusitis management during pregnancy included continuing nasal corticosteroid sprays for CRS maintenance, using pregnancy-safe antibiotics for acute rhinosinusitis and CRS exacerbations, and discontinuing aspirin desensitization for aspirin exacerbated respiratory disease. The manuscript presents detailed recommendations. Conclusions The lack of evidence pertinent to managing rhinosinusitis during pregnancy warrants future trials. Expert recommendations constitute the current best available evidence. PMID:26800862

Background Maternal obesity is emerging as a public health problem, recently highlighted together with maternal under-nutrition as a ‘double burden’, especially in African countries undergoing social and economic transition. This systematic review was conducted to investigate the current evidence on maternal obesity in Africa. Methods MEDLINE, EMBASE, Scopus, CINAHL and PsycINFO were searched (up to August 2014) and identified 29 studies. Prevalence, associations with socio-demographic factors, labour, child and maternal consequences of maternal obesity were assessed. Pooled risk ratios comparing obese and non-obese groups were calculated. Results Prevalence of maternal obesity across Africa ranged from 6.5 to 50.7%, with older and multiparous mothers more likely to be obese. Obese mothers had increased risks of adverse labour, child and maternal outcomes. However, non-obese mothers were more likely to have low-birthweight babies. The differences in measurement and timing of assessment of maternal obesity were found across studies. No studies were identified either on the knowledge or attitudes of pregnant women towards maternal obesity; or on interventions for obese pregnant women. Conclusions These results show that Africa's levels of maternal obesity are already having significant adverse effects. Culturally adaptable/sensitive interventions should be developed while monitoring to avoid undesired side effects. PMID:26487702

Background. Reflexology is one of the top forms of complementary and alternative medicine in the UK and is used for healthcare by a diverse range of people. However, it is offered by few healthcare providers as little scientific evidence is available explaining how it works or any health benefits it may confer. The aim of this review was to assess the current evidence available from reflexology randomised controlled trials (RCTs) that have investigated changes in physiological or biochemical outcomes. Methods. Guidelines from the Cochrane Handbook of Systematic Reviews of Interventions were followed: the following databases were searched from inception to December 2013: AMED, CAM Quest, CINAHL Plus, Cochrane Central Register of Controlled Trials, Embase, Medline Ovid, Proquest, and Pubmed. Risk of bias was assessed independently by two members of the review team and overall strength of the evidence was assessed using the Grading of Recommendations, Assessment, Development, and Evaluation guidelines. Results. Seventeen eligible RCTs met all inclusion criteria. A total of 34 objective outcome measures were analysed. Although twelve studies showed significant changes within the reflexology group, only three studies investigating blood pressure, cardiac index, and salivary amylase resulted in significant between group changes in favour of reflexology. The overall quality of the studies was low. PMID:24883067

The most common biliary complication after liver transplantation is anastomotic stricture (AS) and it can occur isolated or in combination with other complications. Liver graft from a cadaveric donor or a living donor has an influence on the incidence of biliary strictures as well as on the response to endoscopic treatment. Endoscopic treatment using balloon dilation and insertion of biliary stents by endoscopic retrograde cholangiopancreatography (ERCP) is the initial approach to these complications. Aim The aim of this article is to compare different endoscopic techniques to treat post-liver transplantation biliary strictures. Methods The search was carried out on MEDLINE, EMBASE, Scielo-LILACS and Cochrane Library databases through June 2015. A total of 1100 articles were retrieved. Ten clinical trials were analyzed, and seven were included in the meta-analysis. Conclusions The endoscopic treatment of AS was equally effective when compared the use of fully covered self-expandable metal stents (FCSEMS) vs. plastic stents, but the use of FCSEMS was associated with a lower complication risk. The treatment of AS with balloon dilation or balloon dilation associated with plastic stents presented similar results. Deceased donor liver transplantation reduced the risk of biliary stenosis and the endoscopic treatment in these patients was more effective when compared with Living donor liver transplantation.

This review will focus on the rates, clinical characteristics, risk factors and methods of self-harm and suicide in different ethnic groups in the United Kingdom, providing an update synthesis of recent literature. Studies that met the inclusion criteria between 2003 and 2013 were reviewed using the following databases: MEDLINE, PsycINFO, EMBASE and CINAHL. The methodological quality of each study was then assessed using a structured scoring system. A total of 2,362 articles were retrieved, 10 of which matched the inclusion criteria were reviewed. Significant differences were found in the rates of self-harm between ethnic groups with Asian males being least likely to self-harm and Black females being most likely to self-harm. Also, Black and South Asian people were less likely to repeat self-harm. Factors that may help protect or predispose individuals to self-harm or attempt suicide (such as religion, mental health and coping styles) also differ between ethnic groups. There are clear ethnic differences in self-harm and suicide, which may be affected by factors such as cultural pressures and prevalence of mental illness. An awareness of these differences is vital to help prevent further attempts of self-harm and suicide. Further research into differences between ethnic and cultural groups and self-harm continues to be important. © The Author(s) 2015.

This review aimed to (1) summarise the psychosocial needs of children/adolescents (0-18 years) with a parent with cancer across the illness trajectory (diagnosis to bereavement) and (2) evaluate existing interventions for this population. Medline, CINAHL, PsychInfo, EMBASE and Social Work Abstracts were systematically searched for articles published from 1985 to 2015. Of 98 full text articles retrieved, 12 reported on children's psychosocial needs, and 12 intervention studies were identified. Each article was appraised in accordance with the Mixed Method Appraisal Tool. Three factors emerged as critical to consider in future intervention development: (1) Children need age-appropriate information about their parent's cancer; (2) Children require support communicating with parents, family members and health professionals and (3) Children need an environment where they feel comfortable sharing positive/negative emotions and can have their experiences normalised among peers. All intervention studies reported at least one positive outcome, however, only five reported significant improvements in child/family functioning based on validated quantitative measure/s. Variability in study design and quality, combined with considerable heterogeneity in intervention characteristics and outcome variables limited the conclusions, which could be drawn. Therefore, further carefully designed and scientifically evaluated interventions for children facing a parent's cancer diagnosis are clearly warranted. © 2016 John Wiley & Sons Ltd.

Uterine perforation by intrauterine devices (IUDs) is a rare but well recognized complication. In the past, the presence of adhesions and perforation of viscera often resulted in the need for a laparotomy to remove the IUD. However, advances in laparoscopic technique have allowed surgeons to safely retrieve perforated IUDs. In this review, we analyze uterine perforation by an IUD and assess laparoscopic vs. open methods for removal of a perforated IUD. A systematic search strategy was applied to several electronic bibliographic databases: Medline/Pubmed, Embase, Cochrane Library, and OCLC PapersFirst. Key words used were IUD, laparoscopy, and uterine perforation. One hundred seventy-nine cases of attempted laparoscopic removal of perforated IUDs were identified in the English literature between 1970 and 2009. Patient age ranged from 17 to 49 years. Diagnostic laparoscopy was performed in all 179 cases reported. Laparoscopic removal of perforated IUDs was achieved successfully in 64.2% (115/179) of cases. This systematic review highlights how advances in laparoscopic technique and skill have allowed surgeons to safely retrieve IUDs without laparotomy. We recommend an attempt at laparoscopic removal as first-line treatment in symptomatic patients and as a reasonable treatment option in asymptomatic patients. Copyright © 2012 Elsevier Inc.

Given the burden associated with vehicle-related trauma, there is interest in time and cost effective methods of providing information to assist recovery. This systematic review aims to address the question: "Do targeted early information interventions improve outcomes following vehicle--related injuries for persons of working age?" Ovid Medline, EMBASE, PsychINFO and Cochrane databases were searched for studies published between 1990-April 2011. Included studies were randomized or pseudo--randomized controlled trials of information interventions delivered to working age persons following vehicle-related injuries. Two reviewers independently selected and appraised the studies. Sixteen publications (13 primary studies) met the inclusion criteria and were assessed for bias. Hetero-geneity in terms of the information interventions and measured outcomes was encountered. In 4 of the included studies, the intervention was positively associated with at least one outcome reported. Methodological issues limited the conclusions that could be drawn. Following vehicle-related trauma, people often experience difficulties in ongoing functioning. The current evidence neither supports nor fails to support the effectiveness of information interventions in promoting injury recovery. There is a need for larger more methodologically and conceptually rigorous randomized controlled trials that better consider the type and timing of the intervention.

Eczema is a common skin condition that impairs children's daily life activities and quality of life. Previous research shows that gut microbiome composition plays an important role in the development of eczema. The present review summarizes evidence on environmental factors related to altered gut microbiota in children with eczema. We searched Medline, PubMed, Embase, and the Cochrane database of Systematic Reviews through October 2015. The search strategy focused on articles published in peer-reviewed, English-language journals with no publication year limit. Only original studies and review articles that reported environmental factors on gut microbiome specific to eczema were included in this review. We selected six studies (total 1990 participants) for full review and identified that the composition of gut microbiota specific to eczema could be influenced by the following environmental factors: length of gestation, mode of delivery, type of feeding, method of treatment, number of older siblings, and other lifestyle factors. There has been inconsistent empirical evidence as to the modulatory effects of gut microbiota on immunological functions in children with eczema. Further research on the environmental-host-microbial interaction is needed to develop a strong base of knowledge for the development and implementation of prevention strategies and policies for eczema.

Retinal detachment

2014-01-01

Introduction Rhegmatogenous retinal detachment (RRD) is the most common form of retinal detachment, where a retinal 'break' allows the ingress of fluid from the vitreous cavity to the subretinal space, resulting in retinal separation. It occurs in about 1 in 10,000 people a year. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of different surgical interventions in people with rhegmatogenous retinal detachment? What are the effects of interventions to treat proliferative vitreoretinopathy occurring as a complication of retinal detachment or previous treatment for retinal detachment? We searched: Medline, Embase, The Cochrane Library, and other important databases up to September 2013 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 14 studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review, we present information relating to the effectiveness and safety of the following interventions: corticosteroids, daunorubicin, fluorouracil plus low molecular weight heparin, pneumatic retinopexy, scleral buckling, short-acting or long-acting gas tamponade, silicone oil tamponade, and vitrectomy.

Introduction. Physical, mental, and social consequences of malocclusion may impact the quality of life. The aim of this review is to describe main factors motivating parents for orthodontic treatment for their children. Methods. A systematic review study design was used to identify articles analyzing different motivational factors in orthodontic treatment appearing in Medline database, EMBASE, and Google Scholar. The search terms used were teasing, motivating factors, orthodontics, malocclusion, quality of life, smile attractiveness, and perception of malocclusion. Papers selected up to May 2013 included retrospective and prospective longitudinal studies, randomized control trials, cross-sectional studies, reviews, and meta-analyses. Results. 13 articles included in this review identified aesthetics as the main motivational factor in orthodontic treatment. Children mention teeth crowding, large overbite, missing teeth, and largest maxillary anterior irregularities also as motivational factors. Parents want their children to look nice and worry of being accused of neglecting parental duties. Conclusions. Dissatisfaction with one's appearance, dentist recommendation, interest and worries of parents, and the impact of peers who wear braces rank among the main motivation factors of seeking orthodontic treatment. Understanding these factors allows better planning of resources and better assessment of the requirements and priorities of treatment. PMID:24963296

Background A post-operative pancreatic fistula (POPF) is a major cause of morbidity and mortality after a pancreaticoduodenectomy (PD). This systematic review aimed to identify all scoring systems to predict POPF after a PD, consider their clinical applicability and assess the study quality. Method An electronic search was performed of Medline (1946–2014) and EMBASE (1996–2014) databases. Results were screened according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, and quality assessed according to the QUIPS (quality in prognostic studies) tool. Results Six eligible scoring systems were identified. Five studies used the International Study Group on Pancreatic Fistula (ISGPF) definition. The proposed scores feature between two and five variables and of the 16 total variables, the majority (12) featured in only one score. Three scores could be fully completed pre-operatively whereas 1 score included intra-operative and two studies post-operative variables. Four scores were internally validated and of these, two scores have been subject to subsequent multicentre review. The median QUIPS score was 38 out of 50 (range 16–50). Conclusion These scores show potential in calculating the individualized patient risk of POPF. There is, however, much variation in current scoring systems and further validation in large multicentre cohorts is now needed. PMID:26456948

[Which treatments for infantile colics?].

Infantile colics or excessive crying represent a source of stress for parents and a frequent reason for encounter in primary care. To assess the effectiveness of treatments of this syndrome from a systematic review. Medline, Cochrane and Embase databases. We used the following inclusion criteria: therapeutic assessment of infant colics or excessive crying, randomized controlled trials or meta-analyses, published in English or French language. Thirty-one randomized controlled trials and one meta-analysis have been included. Allopathic drugs have not proved effectiveness (simethicone, lactase) and some of them can cause potentially serious adverse reactions (dicyclomine). Protein hydrolysate or soy formulas seem to be effective, but soy milk can induce allergies. Sucrose solutions provide some benefit in studies with low level of evidence. Effectiveness is likely for a probiotics (Lactobacillus reuteri) and for herbal mixtures containing fennel extracts. Evidence is lacking for manual (osteopathy, acupuncture) and behavioural therapies (decreased stimulations, reassurance of parents). The definition of infantile colics and the methods used for crying measurement changed across trials. The included trials were of variable quality, especially with no double-blind procedure in 17 trials. The most validated treatments for infantile colics are the substitution of cows' milk by a hydrolysed formula, the use of L. reuteri and of fennel extracts. Copyright © 2012 Elsevier Masson SAS.

2011-01-01

Medline, Embase, The Cochrane Oral Health Group's Trials Register, CENTRAL, UK National Research Register, ISI Proceedings, hand search of relevant journals for 2000-2008. References from selected articles and contact with authors. Randomised controlled trials in any language comparing scaling and root planing (SRP) alone and SRP with PDT in patients with chronic periodontitis, with a mean follow up of at least 12 weeks. The primary outcome measure was the change in clinical attachment loss (CAL). Secondary outcomes were changes in probing depth (PD) and gingival recession (GR). Data were extracted by a single reviewer using a standard extraction form. Quality was assessed using both the Jadad scale and the allocation concealment component of the Cochrane risk of bias tool. Meta-analysis was conducted using the random effects model. Heterogeneity was assessed using the chi-squared-based Q statistic method and Higgins' I(2) test. Four trials with 101 participants were included. The risk of bias of these trials was considered to be moderate. The mean difference in CAL at 12 weeks was 0.29 mm (95% CI 0.08-0.50, p=0.007). Heterogeneity was high using both the Chi(2) and I(2) tests. The review suggests there may be a minor improvement in clinical attachment loss at 12 weeks. It is unclear whether this is a clinically meaningful improvement.

Introduction Hyperthyroidism is characterised by high levels of serum thyroxine and triiodothyronine, and low levels of thyroid-stimulating hormone. The main causes of hyperthyroidism are Graves' disease, toxic multinodular goitre, and toxic adenoma. About 20 times more women than men have hyperthyroidism. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of drug treatments for primary hyperthyroidism? What are the effects of surgical treatments for primary hyperthyroidism? What are the effects of treatments for subclinical hyperthyroidism? We searched: Medline, Embase, The Cochrane Library and other important databases up to June 2007 (BMJ Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 14 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review we present information relating to the effectiveness and safety of the following interventions: adding thyroxine to antithyroid drugs (carbimazole, propylthiouracil, and thiamazole), antithyroid drugs (carbimazole, propylthiouracil, and thiamazole), radioactive iodine, and thyroidectomy.

The value of temporary intraoperative porto-caval shunts (TPCS) in cava-sparing liver transplantation is discussed controversially. Aim of this meta-analysis was to analyze the impact of temporary intraoperative porto-caval shunts on liver injury, primary non-function, time of surgery, transfusion of blood products and length of hospital stay in cava-sparing liver transplantation. A systematic search of MEDLINE/PubMed, EMBASE and PsycINFO retrieved a total of 909 articles, of which six articles were included. The combined effect size and 95 % confidence interval were calculated for each outcome by applying the inverse variance weighting method. Tests for heterogeneity (I 2 ) were also utilized. Usage of a TPCS was associated with significantly decreased AST values, significantly fewer transfusions of packed red blood cells and improved postoperative renal function. There were no statistically significant differences in primary graft non-function, length of hospital stay or duration of surgery. This meta-analysis found that temporary intraoperative porto-caval shunts in cava-sparing liver transplantation reduce blood loss as well as hepatic injury and enhance postoperative renal function without prolonging operative time. Randomized controlled trials investigating the use of temporary intraoperative porto-caval shunts are needed to confirm these findings.

Aims. The aim of this review is to provide a comprehensive overview of the available literature on preventing perineal trauma with the EpiNo. Methods. We perfomed a literature research in the MedLine and EMBASE databases for studies referring to EpiNo published between 1990 and 2014, without restrictions for language and study type. Results. Five published studies were identified, regarding the effect of EpiNo on the rate of episiotomy and perineal tears, pelvic floor muscle function, and fetal outcome. The device seems to reduce episiotomy and perineal tears' rate, as well as the risk for levator ani microtrauma and avulsion, though not always statistically significant. It does not seem to have an effect on duration of second stage of labour and fetal outcome. The device is well tolerated and the adverse events are rare and mild. However, design and reporting bias in the reviewed articles do not allow evidence based conclusions. Conclusions. The EpiNo device seems to be promising, with potential positive effects on natural birth, while being uncomplicated to use and without major complications. Well designed, randomized trials are needed in order to understand the effects of EpiNo on pelvic floor and make evidence based recommendations on its use. PMID:26981126

Point-of-care (POC) tests enable rapid results and are well established in medical practice. Recent advances in analytical techniques have led to a new generation of POC devices that will alter gastrointestinal diagnostic pathways. This review aims to identify current and new technologies for the POC diagnosis of gastrointestinal cancer. A structured search of the Embase and Medline databases was performed. Papers reporting diagnostic tests for gastrointestinal cancer available as a POC device or containing a description of feasibility for POC application were included. Studies recovered were heterogeneous and therefore results are presented as a narrative review. Six diagnostic methods were identified (fecal occult blood, fecal proteins, volatile organic compounds, pyruvate kinase isoenzyme type M2, tumour markers and DNA analysis). Fecal occult blood testing has a reported sensitivity of 66%-85% and specificity greater than 95%. The others are at a range of development and clinical application. POC devices have a proven role in the diagnosis of gastrointestinal cancer. Barriers to their implementation exist and the transition from experimental to clinical medicine is currently slow. New technologies demonstrate potential to provide accurate POC tests and an ability to diagnose gastrointestinal cancer at an early stage with improved clinical outcome and survival. PMID:25892860

Optical coherence tomography (OCT) is an emergent imaging tool used for noninvasive diagnosis of skin diseases. The present meta-analysis was carried out to assess the accuracy of OCT for the diagnosis of skin cancer. We conducted a systematic literature search though EMBASE, Medline, PubMed, the Cochrane Library, and Web of Science database for relevant articles published up to June 6, 2017. The quality of the included studies was assessed using the QUADAS-2 tool and the Oxford Levels of Evidence Scale. Statistical analyses were conducted using the software Meta-Disc version 1.4 and STATA version 12.0. A total of 14 studies involving more than 813 patients with a total of 1958 lesions were included in our analyses. The pooled sensitivity and specificity of OCT for skin cancer diagnoses were 91.8% and 86.7%, respectively. Subgroup analysis showed that the pooled sensitivities of OCT for detecting basal cell carcinoma (BCC), squamous cell carcinoma (SCC), actinic keratosis, and malignant melanoma were 92.4%, 92.3%, 73.8%, and 81.0%, respectively. The pooled specificities were 86.9%, 99.5%, 91.5%, and 93.8%, respectively. OCT appears to be useful for the detection of BCC and SCC. It is a valuable diagnostic method when screening for early skin cancers.

Introduction Postoperative anastomotic leak and stricture are dramatic events that cause increased morbidity and mortality, for this reason it's important to evaluate which is the best way to perform the anastomosis. Aim To compare the techniques of manual (hand-sewn) and mechanic (stapler) esophagogastric anastomosis after resection of malignant neoplasm of esophagus, as the occurrence of anastomotic leak, anastomotic stricture, blood loss, cardiac and pulmonary complications, mortality and surgical time. Methods A systematic review of randomized clinical trials, which included studies from four databases (Medline, Embase, Cochrane and Lilacs) using the combination of descriptors (anastomosis, surgical) and (esophagectomy) was performed. Results Thirteen randomized trials were included, totaling 1778 patients, 889 in the hand-sewn group and 889 in the stapler group. The stapler reduced bleeding (p <0.03) and operating time (p<0.00001) when compared to hand-sewn after esophageal resection. However, stapler increased the risk of anastomotic stricture (NNH=33), pulmonary complications (NNH=12) and mortality (NNH=33). There was no significant difference in relation to anastomotic leak (p=0.76) and cardiac complications (p=0.96). Conclusion After resection of esophageal cancer, the use of stapler shown to reduce blood loss and surgical time, but increased the incidence of anastomotic stricture, pulmonary complications and mortality.

2015-10-11

This review critically evaluates the literature on posttraumatic growth in survivors of interpersonal violence, integrating the findings from 12 quantitative and 4 qualitative studies. The following databases were searched using predetermined terms: AMED, EMBASE, MEDLINE, PsycINFO, BNI, CINAHL, and Web of Knowledge. The review's findings suggest that the mean prevalence of growth in interpersonal violence survivors is around 71% (range 58-99%). The highest level of growth was consistently experienced in the "appreciation of life" domain. However, survivors reported growth in the four remaining domains: "personal strength," "new possibilities," "experience of relationships with others," and "outlook on life." The nature of the relationship between growth and distress was inconsistent across studies. A combination of pretrauma, peritrauma, and posttrauma variables were found to be related to the degree of growth survivors experienced. Methodological weaknesses of the quantitative studies included the predominant use of retrospective, cross-sectional, correlational designs, discrepancy in the measurement of growth, insufficient sample sizes for power calculations in five studies and limited external validity. Qualitative findings were limited by sampling methods, insufficient information about interview schedules, the lack of credibility checks, and evidence of reflexivity demonstrated by some studies. Implications for practice, policy, and future research are discussed. © The Author(s) 2015.

Abstract Background: Integrative medicine is claimed to improve symptoms of lupus nephritis. No systematic reviews have been performed for the application of integrative medicine for lupus nephritis on patients with systemic lupus erythematosus (SLE). Thus, this review will aim to evaluate the current evidence on the efficacy of integrative medicine for the management of lupus nephritis in patients with SLE. Methods and analyses: The following electronic databases will be searched for studies published from their dates of inception February 2018: Medline, EMBASE and the Cochrane Central Register of Controlled Trials (CENTRAL), as well as 6 Korean medical databases (Korea Med, the Oriental Medicine Advanced Search Integrated System [OASIS], DBpia, the Korean Medical Database [KM base], the Research Information Service System [RISS], and the Korean Studies Information Services System [KISS]), and 1 Chinese medical database (the China National Knowledge Infrastructure [CNKI]). Study selection, data extraction, and assessment will be performed independently by 2 researchers. The risk of bias (ROB) will be assessed using the Cochrane ROB tool. Dissemination: This systematic review will be published in a peer-reviewed journal and disseminated both electronically and in print. The review will be updated to inform and guide healthcare practice and policy. Trial registration number: PROSPERO 2018 CRD42018085205 PMID:29595669

Background The association between obesity and gastroesophageal reflux disease has a high incidence and may be present in half of obese patients with surgical indication. Bariatric operations can also induce reflux alone - differently from BMI factors - and its mechanisms are dependent on the type of procedure performed. Objective To perform a literature review comparing the two procedures currently most used for surgical treatment of obesity and analyze their relationship with the advent of pre-existing reflux disease or its appearance only in postoperative period. Method The literature was reviewed in virtual database Medline/PubMed, SciELO, Lilacs, Embase and Cochrane crossing the following MeSH descriptors: gastric bypass AND / OR anastomosis, Roux-en-Y AND / OR gastroesophageal reflux AND / OR gastroenterostomy AND / OR gastrectomy AND / OR obesity AND / OR bariatric surgery AND / OR postoperative period. A total of 135 relevant references were considered but only 30 were used in this article. Also was added the experience of the authors of this article in handling these techniques on this field. Conclusion The structural changes caused by surgical technique in vertical gastrectomy shows greater commitment of antireflux mechanisms predisposing the induction of GERD postoperatively compared to the surgical technique performed in the gastrointestinal Bypass Roux-en-Y.

Background. Ischemia-reperfusion injury is a major cause of post-liver-surgery complications. Ischemic preconditioning (IPC) has been demonstrated to protect against ischemia-reperfusion injury. Clinical studies have examined IPC in liver surgery but with conflicting results. This systematic review aimed to evaluate the effects of IPC on outcome in clinical liver surgery. Methods. An electronic search of OVID Medline and Embase databases was performed to identify studies that reported outcomes in patients undergoing liver surgery subjected to IPC. Basic descriptive statistics were used to summarise data from individual clinical studies. Results. 1093 articles were identified, of which 24 met the inclusion criteria. Seven topics were selected and analysed by subgroup. There were 10 studies in cadaveric liver transplantation, 2 in living-related liver transplantation, and 12 in liver resection. IPC decreases hepatocellular damage in liver surgery as determined by transaminases but does not translate to any significant clinical benefit in orthotopic liver transplant or liver resection. Conclusions. Available clinical evidence does not support routine use of IPC in liver surgery as it does not offer any apparent benefit in perioperative outcome. Further clinical studies will need to be carried out to determine the subset of patients that will benefit from IPC. PMID:25756045

Hutton, Brian; Ng, Terry; Shorr, Risa; Clemons, Mark

2015-01-01

Background. Many cancer patients receive supplemental ascorbate (vitamin C) in the belief that it synergizes the anticancer effects of chemotherapy and reduces its toxicity. Methods. A systematic review was performed to evaluate the antitumor effects and toxicity of ascorbate treatment. Medline (1946 to March 2014), EMBASE (1947 to March 2014), and the Cochrane central register (1993 to March 2014) were searched for randomized and observational studies. Results. Of 696 identified records, 61 full-text articles were screened and 34 were included. In total, 5 randomized controlled trials (RCTs) (n = 322), 12 phase I/II trials (n = 287), 6 observational studies (n = 7,599), and 11 case reports (n = 267) were identified. Because of study heterogeneity, no meta-analyses were performed. No RCTs reported any statistically significant improvements in overall or progression-free survival or reduced toxicity with ascorbate relative to control arm. Evidence for ascorbate’s antitumor effects was limited to case reports and observational and uncontrolled studies. Conclusion. There is no high-quality evidence to suggest that ascorbate supplementation in cancer patients either enhances the antitumor effects of chemotherapy or reduces its toxicity. Given the high financial and time costs to patients of this treatment, high-quality placebo-controlled trials are needed. PMID:25601965

AIM: To systematically review the survival outcomes relating to extramural venous invasion in rectal cancer. METHODS: A systematic review was conducted using PRISMA guidelines. An electronic search was carried out using MEDLINE, EMBASE, CINAHL, Cochrane library databases, Google scholar and PubMed until October 2014. Search terms were used in combination to yield articles on extramural venous invasion in rectal cancer. Outcome measures included prevalence and 5-year survival rates. These were graphically displayed using Forest plots. Statistical analysis of the data was carried out. RESULTS: Fourteen studies reported the prevalence of extramural venous invasion (EMVI) positive patients. Prevalence ranged from 9%-61%. The pooled prevalence of EMVI positivity was 26% [Random effects: Event rate 0.26 (0.18, 0.36)]. Most studies showed that EMVI related to worse oncological outcomes. The pooled overall survival was 39.5% [Random effects: Event rate 0.395 (0.29, 0.51)]. CONCLUSION: Historically, there has been huge variation in the prevalence of EMVI through inconsistent reporting. However the presence of EMVI clearly leads to worse survival outcomes. As detection rates become more consistent, EMVI may be considered as part of risk-stratification in rectal cancer. Standardised histopathological definitions and the use of magnetic resonance imaging to identify EMVI will improve detection rates in the future. PMID:26819536

Assessing Predictive Validity of Pressure Ulcer Risk Scales- A Systematic Review and Meta-Analysis

PARK, Seong-Hi; LEE, Hea Shoon

2016-01-01

Background: The purpose of this study was to present a scientific reason for pressure ulcer risk scales: Cubbin& Jackson modified Braden, Norton, and Waterlow, as a nursing diagnosis tool by utilizing predictive validity of pressure sores. Methods: Articles published between 1966 and 2013 from periodicals indexed in the Ovid Medline, Embase, CINAHL, KoreaMed, NDSL, and other databases were selected using the key word “pressure ulcer”. QUADAS-II was applied for assessment for internal validity of the diagnostic studies. Selected studies were analyzed using meta-analysis with MetaDisc 1.4. Results: Seventeen diagnostic studies with high methodological quality, involving 5,185 patients, were included. In the results of the meta-analysis, sROC AUC of Braden, Norton, and Waterflow scale was over 0.7, showing moderate predictive validity, but they have limited interpretation due to significant differences between studies. In addition, Waterlow scale is insufficient as a screening tool owing to low sensitivity compared with other scales. Conclusion: The contemporary pressure ulcer risk scale is not suitable for uninform practice on patients under standardized criteria. Therefore, in order to provide more effective nursing care for bedsores, a new or modified pressure ulcer risk scale should be developed upon strength and weaknesses of existing tools. PMID:27114977

Introduction Whiplash injuries are common in society, but clinical interventions are inconclusive on the most effective treatment. Research and reviews have been completed with the goal of determining clinical interventions that are effective for whiplash injuries and disorders, but literature has not recently been summarised on best practices for cervical spine interventions for adults with chronic whiplash. Purpose The objective of this narrative review is to update and expand on previous works, to provide recommendations for clinical interventions and future research in the area of cervical spine rehabilitation for adults with chronic whiplash-associated disorder. Method The Arskey and O’Malley methodology was used for this narrative review. CINHAL, EMBASE, Medline, PsychInfo, Scopus, Web of Science, as well as grey literature, were searched from 2003 to April 2017. Two reviewers screened titles and abstracts for relevance to the review, and content analysis summarised the study findings. A total of 14 citations were included in the final review. Findings Exercise-based interventions targeted at the cervical spine appear most beneficial for adults with chronic whiplash-associated disorder (WAD). Invasive interventions still require more rigorous studies to deem their effectiveness for this population. Conclusion Further research is required to investigate and determine clinically relevant results for cervical spine intervention in patients with chronic WAD. PMID:29719724
