We report a systematic review of studies indexed in PubMed reporting annual rates of low-trauma falls and associated osteoporotic fractures among older community-dwelling people (age ≥ 50 years. An osteoporotic fracture was defined as either a fracture resulting from a low-impact fall in subjects with clinical osteoporosis, a fall resulting in an investigator-defined osteoporotic fracture, or a fall resulting in a low-trauma fracture. Rates are presented using descriptive statistics. Meta-analysis was conducted for statistically homogeneous data sets.Results: The median (range annual fall prevalence rates (median proportion of people who experienced one or more falls during the past year for cohorts of women and men (10 determinations, women alone (seven determinations, and men alone (four determinations were, respectively, 0.334 (0.217–0.625, 0.460 (0.372–0.517, and 0.349 (0.284–0.526.

    This study aims to systematically review epidemiological studies that evaluate the relationship between meteorology and the incidence of hip fracture (HF). After a search in Scopus, PubMed, and Embase, two independent authors assessed the relevance of studies and extracted data for description. From each study, we extracted the geographic and temporal scope, design, study variables (meteorological and related to HF), statistical analysis, and estimated associations. Of a total of 134 works, 20 studies were selected. All use an ecological design but one case-crossover. Most studies have been conducted in northern latitudes. The analysis methodology did not take into account the temporal structure of the data in 10 studies (regression and linear correlations); the rest used Poisson regression (7) and ARIMA model (3). Most studies showed significant positive associations with rainfall, especially in the form of snow: HF relative risk (RR) on days with precipitation vs. days without precipitation that ranged from 1.14 (95 % confidence interval (CI)1.04 to 1.24) to 1.60 (95 % CI 1.06 to 2.41), the temperature, with RR by one degree Celsius decline from 1.012 (95 % CI 1.004 to 1.020) to 1.030 (95 % CI 1.023 to 1.037), and wind (3) RR FC windiest days vs. calm days: 1.32 (95 % CI 1.10 to 1.58) to 1.35 (95 % CI 0.88 to 2.08). This review shows that analytic methods are very heterogeneous and poorly adapted to the temporary nature of the data. Studies confirm a certain seasonality, with more fractures in winter and meaningful relationships with meteorological conditions typical of this season.

    2016-07-01

    An unfavourable and unanticipated pattern of the mandibular sagittal split osteotomy is generally referred to as a 'bad split'. Few restorative techniques to manage the situation have been described. In this article, a classification of reported bad split pattern types is proposed and appropriate salvage procedures to manage the different types of undesired fracture are presented. A systematic review was undertaken, yielding a total of 33 studies published between 1971 and 2015. These reported a total of 458 cases of bad splits among 19,527 sagittal ramus osteotomies in 10,271 patients. The total reported incidence of bad split was 2.3% of sagittal splits. The most frequently encountered were buccal plate fractures of the proximal segment (types 1A-F) and lingual fractures of the distal segment (types 2A and 2B). Coronoid fractures (type 3) and condylar neck fractures (type 4) have seldom been reported. The various types of bad split may require different salvage approaches.

    Because of the low incidence of penile fracture, many aspects of the diagnostic process and of the surgical and functional outcomes are rarely reported. To systematically review the current literature on the surgical management of penile fracture, focusing on etiology, diagnosis, functional outcomes, and postoperative complications. The present review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) declaration standards for systematic reviews. A systematic search for the terms penile fracture, fracture of penis, trauma of penis, rupture of corpora cavernosa, and immediate management of penile fracture was been carried out in the PubMed, EMBASE, Cochrane, SCOPUS, and Science Citation Index databases. Etiology of penile fracture, clinical presentation, types of radiologic investigations and their accuracy, surgical approach, suture material used for tunica repair, timing of surgical exploration, intraoperative findings, surgical complications, and functional outcomes. The total number of patients analyzed was 438, and the patients' an average age was 36 years. The most frequent reported cause of penile fracture was sexual intercourse (80% of cases). The most common finding at examination was a penile hematoma (97.5%). Although operator dependent, in experienced hands, ultrasonography was found to be a useful tool in confirming the location of the albuginea tear and identifying the presence of any concomitant urethral injury, helping the surgeon to choose the best surgical approach. Early surgical repair of a penile fracture was found to be a safe procedure, although long-term complications are not uncommon. Tertiary referral centers that managed a larger number of cases seemed to obtain more satisfactory long-term results with a significantly smaller number of complications. A low incidence of postoperative complications and full satisfactory functional outcomes are reported when early repair is

    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 (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.

    Background The use of osteoanabolic agents to facilitate fracture healing has been of heightened interest to the field of orthopaedic trauma. This study aimed to evaluate the evidence of teriparatide for fracture healing and functional recovery in osteoporotic patients. Methods We performed a literature search in PubMed, EMBASE, Web of Science, and the Cochrane Library using terms including “Fracture” [tiab] AND “Teriparatide [tiab] OR “PTH” [tiab]. Results This systematic review included 6 randomized clinical trials, 4 well-controlled retrospective studies, and 1 retrospective post hoc subgroup analysis. Fracture location was 2 in pelvis, 3 in proximal femur, 1 in distal femur, 1 in shoulder, 2 in wrist and 2 in spine. The use of teriparatide yielded positive effects on radiographic bone healing in 6 studies, but was not associated with better radiographic outcome in 3. In terms of functional recovery, teriparatide injection was related with decrease in pain or shorter time to mobilization in 6 studies, but not related with pain numerical scale and mobility in 3. Conclusions Our findings suggest that teriparatide provide selective advantages to fracture healing or functional recovery in the management of osteoporotic fractures. A better understanding of the role of teriparatide on osteoporotic fractures requires greater evidences from large volume prospective trials. PMID:28326303

    2016-03-01

    Despite the frequent occurrence of these injuries, we know little about the natural history of Salter-Harris II (SH II) distal radius fractures. We conducted a systematic review of studies examining the radiographic and clinical outcomes of nonoperatively managed SH II distal radius fractures. Systematic searches of the MEDLINE and Cochrane computerized literature databases and manual searches of bibliographies were performed. We reviewed both descriptive and quantitative data. Seven studies including 434 SH II fractures were reviewed. Two studies reported clinical outcomes based on patient age, but neither study described a statistical correlation between patient age and outcome. Two studies discussed the effect of age on radiographic outcome and reported higher rates of anatomic remodeling in children 10 years or younger. Two studies with long-term (average follow-up greater than 8 years) clinical results reported complication rates of 5%. Long-term follow-up of radiographic outcomes appeared in 4 studies with variable results. Five studies reported the frequency of premature physeal arrest after SH II fractures, with results ranging from 0% to 4.3%. Based on this review, no recommendations can be made as to what defines an acceptable reduction or which fractures would benefit from surgical intervention. Angular deformity seems to correct to an acceptable alignment in patients less than 10 years of age, but these younger patients seem to be at higher risk for symptomatic shortening if a growth arrest occurs. Redisplacement after reduction is fairly common, and other more severe complications such as pain, loss of motion, and nerve injury can occur.

  12. Femoral nerve block versus intravenous fentanyl in adult patients with hip fractures - a systematic review

    Flávia Vieira Guimarães Hartmann

    Full Text Available Abstract Background: Hip fractures configure an important public health issue and are associated with high mortality taxes and lose of functionality. Hip fractures refer to a fracture occurring between the edge of the femoral head and 5 cm below the lesser trochanter. They are common in orthopedic emergencies. The number of proximal femoral fractures is likely to increase as the population ages. The average cost of care during the initial hospitalization for hip fracture can be estimated about US$ 7,000 per patient. Femoral fractures are painful and need immediate adequate analgesia. Treating pain femoral fractures is difficult because there are limited numbers of analgesics available, many of which have side effects that can limit their use. Opiates are the most used drugs, but they can bring some complications. In this context, femoral nerve blocks can be a safe alternative. It is a specific regional anesthetic technique used by doctors in emergency medicine to provide anesthesia and analgesia of the affected leg. Objective: To compare the analgesic efficacy of intravenous fentanyl versus femoral nerve block before positioning to perform spinal anesthesia in patients with femoral fractures assessed by Pain Scales. Methods: A systematic review of scientific literature was conducted. Studies described as randomized controlled trials comparing femoral nerve block and traditional fentanyl are included. Two reviewers (MR and FH independently assessed potentially eligible trials for inclusion. The methodology assessment was based on the tool developed by the Cochrane Collaboration for assessment of bias for randomized controlled trials. The Cochrane Library, Pubmed, Medline and Lilacs were searched for all articles published, without restriction of language or time. Results: Two studies were included in this review. Nerve blockade seemed to be more effective than intravenous fentanyl for preventing pain in patients suffering from a femoral fracture

    Full Text Available The objective of this systematic review was to integrate the information from existing studies to determine the level of evidence and grade of recommendation of the implementation of damage control in unstable thoracic and lumbar fractures in polytraumatized patients. Eighteen papers were collected from different databases by keywords and Mesh terms; the level of evidence and grade of recommendation, the characteristics of the participants, the time of fracture fixation, the type of approach and technique used, the length of stay in the intensive care unit, the days of dependence on mechanical ventilator, and the incidence of complications in patients were assessed. The largest proportion of the studies were classified as level 4 evidence and grade C of recommendation which is favorable to the implementation of damage control in unstable thoracic and lumbar fractures in polytraumatized patients as a positive recommendation, although not conclusive. Most papers advocate fracture stabilization within 72 hours of the injury which is associated with a lower incidence of complications, hospital stay, stay in the intensive care unit and lower mortality.

    The relative effects of internal fixation strategies for intertrochanteric fracture after operation remain uncertain. We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to address this important issue. We searched PubMed, EMBASE and CENTRAL for RCTs that compared different internal fixation implants in patients with intertrochanteric fracture at 6-month follow-up or longer. We ultimately included 43 trials enrolling 6911 patients; most trials were small in sample sizes and events. Their risk of bias was generally unclear due to insufficient reporting. Because of these, no statistically significant differences were present from most of the comparisons across all the outcomes, and no definitive conclusions can be made. However, a number of trials compared two commonly used internal fixation strategies, gamma nail (GN) and sliding hip screw (SHS). There is good evidence suggesting that, compared to SHS, GN may increase the risk of cut out (OR = 1.87, 95% CI, 1.08 to 3.21), re-operation (OR = 1.61, 95% CI, 1.02 to 2.53), intra-operative (OR = 3.14, 95% CI, 1.34 to 7.35) and later fractures (OR = 3.67, 95% CI, 1.37 to 9.83). Future randomized trials or observational studies that are carefully designed and conducted are warranted to establish the effects of alternative internal fixation strategies for intertrochanteric fracture.

    Fragility fractures are fractures that result from mechanical forces that would not ordinarily result in fracture. To evaluate the clinical effectiveness and safety of bisphosphonates [alendronic acid (Fosamax(®) and Fosamax(®) Once Weekly, Merck Sharp & Dohme Ltd), risedronic acid (Actonel(®) and Actonel Once a Week(®), Warner Chilcott UK Ltd), ibandronic acid (Bonviva(®), Roche Products Ltd) and zoledronic acid (Aclasta(®), Novartis Pharmaceuticals UK Ltd)] for the prevention of fragility fracture and to assess their cost-effectiveness at varying levels of fracture risk. For the clinical effectiveness review, six electronic databases and two trial registries were searched: MEDLINE, EMBASE, The Cochrane Library, Cumulative Index to Nursing and Allied Health Literature, Web of Science and BIOSIS Previews, Clinicaltrials.gov and World Health Organization International Clinical Trials Registry Platform. Searches were limited by date from 2008 until September 2014. A systematic review and network meta-analysis (NMA) of effectiveness studies were conducted. A review of published economic analyses was undertaken and a de novo health economic model was constructed. Discrete event simulation was used to estimate lifetime costs and quality-adjusted life-years (QALYs) for each bisphosphonate treatment strategy and a strategy of no treatment for a simulated cohort of patients with heterogeneous characteristics. The model was populated with effectiveness evidence from the systematic review and NMA. All other parameters were estimated from published sources. A NHS and Personal Social Services perspective was taken, and costs and benefits were discounted at 3.5% per annum. Fracture risk was estimated from patient characteristics using the QFracture(®) (QFracture-2012 open source revision 38, Clinrisk Ltd, Leeds, UK) and FRAX(®) (web version 3.9, University of Sheffield, Sheffield, UK) tools. The relationship between fracture risk and incremental net benefit (INB) was

  18. Vertebral Augmentation Involving Vertebroplasty or Kyphoplasty for Cancer-Related Vertebral Compression Fractures: A Systematic Review

    Science.gov (United States)

    2016-01-01

    Background Cancers that metastasize to the spine and primary cancers such as multiple myeloma can result in vertebral compression fractures or instability. Conservative strategies, including bed rest, bracing, and analgesic use, can be ineffective, resulting in continued pain and progressive functional disability limiting mobility and self-care. Surgery is not usually an option for cancer patients in advanced disease states because of their poor medical health or functional status and limited life expectancy. The objectives of this review were to evaluate the effectiveness and safety of percutaneous image-guided vertebral augmentation techniques, vertebroplasty and kyphoplasty, for palliation of cancer-related vertebral compression fractures. Methods We performed a systematic literature search for studies on vertebral augmentation of cancer-related vertebral compression fractures published from January 1, 2000, to October 2014; abstracts were screened by a single reviewer. For those studies meeting the eligibility criteria, full-text articles were obtained. Owing to the heterogeneity of the clinical reports, we performed a narrative synthesis based on an analytical framework constructed for the type of cancer-related vertebral fractures and the diversity of the vertebral augmentation interventions. Results The evidence review identified 3,391 citations, of which 111 clinical reports (4,235 patients) evaluated the effectiveness of vertebroplasty (78 reports, 2,545 patients) or kyphoplasty (33 reports, 1,690 patients) for patients with mixed primary spinal metastatic cancers, multiple myeloma, or hemangiomas. Overall the mean pain intensity scores often reported within 48 hours of vertebral augmentation (kyphoplasty or vertebroplasty), were significantly reduced. Analgesic use, although variably reported, usually involved parallel decreases, particularly in opioids, and mean pain-related disability scores were also significantly improved. In a randomized controlled

    This review analyzes the economic costs of HF in Asia. The availability and quality of studies on the burden of osteoporosis in Asia are very scarce. There is a need to encourage more quality cost of osteoporosis studies based on standardized methods to convince healthcare authorities in implementing appropriate strategies. Osteoporosis fractures, especially hip fractures, impose large economic costs to governments and societies. This review aimed to systematically analyze available evidence on healthcare costs associated with osteoporosis-related hip fractures (HF) in Asia. Articles were systematically sought from databases including PubMed, EMBASE, and EBSCOHost between 2000 and 2015. Total costs associated with HF care, the cost components, and length of stays were retrieved and analyzed. Study designs were also qualitatively analyzed. The availability of published studies on economic burden of HF in Asia is severely lacking with only 15 articles met the inclusion criteria. Even among the included studies, only two studies reported comprehensive costs evaluating all costs including indirect or intangible costs. Most studies satisfactorily reported criteria for conducting economic evaluation, but large variations existed in the methodological design. Due to study design and other influencing factors, large variation in the cost of HF treatment from US$774 to US$14,198.90 (median S$2943), representing an average of 18.95% (range: 3.58-57.05%) of the countries' 2014 GDP/capita, was observed. This highlighted the heavy burden of managing HF in Asia with about 40% of the included studies reported using more than one third of GDP/capita. There is a paucity of burden of illness studies of osteoporosis in the Asian region. For the few available studies, there was a lack of standardization in methodological approach in evaluating the economic burden of the disease. There is a need to encourage more quality burden of illness studies of osteoporosis to inform policymakers

    The aim of this review was to answer the question: Which is the best procedure to follow when there is tooth involvement in the line of mandibular angle fracture, taking into consideration the occurrence of postoperative infection? A systematic literature review using the PubMed (MEDLINE), Virtual Health Library (VHL), Cochrane Library, and Scopus databases was done, and a total of 1007 articles were found. Among these, 13 articles were included in the final review after the papers were read. A series of 1542 mandibular angle fractures with the presence of teeth in the fracture line was obtained. Of 788 cases where the tooth was removed, a postoperative infection occurred in 84 cases; of 754 cases where the tooth was retained, postoperative infection also occurred in 84 cases. Through this review it was observed that there was no significant statistical difference between removing or retaining the tooth in the line of fracture and the occurrence of postoperative infection.

    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.

    Purpose Currently, most rehabilitation services for individuals who sustain a hip fracture are not designed to meet the complex needs of those who also have cognitive impairment. The goal of this review was to identify current best practices for rehabilitation in long term care settings and approaches to optimize outcomes among individuals with dementia and other cognitive impairments post hip fracture. Procedures The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (the PRISMA Statement) was used to guide the review. Five electronic databases, including Pubmed, EMBASE, CINAHL (EBSCO), Medline (EBSCO) and PsycINFO (EBSCO), were searched for intervention studies published in English language journals. Studies were eligible if they focused on rehabilitation interventions post hip fracture among older individuals (≥ 65 years) with cognitive impairment who were living in or transferred to long-term care or post-acute/rehabilitation settings post hip fracture. Studies were excluded if they did not enroll individuals with cognitive impairment, the study was descriptive without any intervention content, or the intervention components were only medication, surgical approach or medical treatment. Main Findings A total of 4,478 records were identified, 1915 of which were duplicative, 2,563 were relevant based on title and after careful review seven studies were included. Two included studies were randomized controlled trials, one was a single group pre- and post-test, one a descriptive comparison between those with and without cognitive impairment, one a case controlled matched trial, one a nonequivalent groups trial, and one a case report. The interventions varied between manipulating the type and amount of exercise or testing multifactorial issues including environmental interventions and the use of an interdisciplinary team to address psychosocial factors, medication management, use of assistive devices, and specific preferences or concerns of the

    With an increasing ageing population, hip fractures have become a major public health issue in the elderly. It is important to examine the health status (HS) and health-related quality of life (HRQOL) of the elderly faced with the epidemic of hip fractures. To provide an overview of reported HS and HRQOL in elderly patients with a hip fracture. A systematic literature search was performed in Embase, Medline, Web of Science, Scopus, CINAHL, Cochrane, PsycINFO, Pubmed, and Google Scholar in July 2014. Studies which reported the HS or HRQOL based on standardised questionnaires in patients older than 65 years with a hip fracture were considered eligible for inclusion. After inspecting the 2725 potentially eligible studies, 49 fulfilled the inclusion criteria. All included studies were randomised controlled trials or prospective cohort studies. The methodological quality of the studies was moderate. Patients' functioning on the physical, social, and emotional domains were affected after a hip fracture. The HS and HRQOL of the majority of patients recovered in the first 6 months after fracture. However, their HS did not return to prefracture level. Mental state, prefracture functioning on physical and psychosocial domains, comorbidity, female gender, nutritional status, postoperative pain, length of hospital stay, and complications were factors associated with HS or HRQOL. Treatment with total hip arthroplasty or hemi-arthroplasty provided better HS than treatment with internal fixation with displaced femoral neck fractures. Supportive psychotherapy in "low-functioning" patients, (home) rehabilitation programmes and nutritional supplementation appeared to have beneficial effects on HS. Optimizing nutrition intake, (home) rehabilitation programmes, and the possibility for psychological counselling in patients with difficulties in the psychosocial dimensions would be recommended after hip fracture surgery. Besides HS questionnaires like EQ-5D and SF-36, adequate

    Previous studies suggested possible bone loss and fracture risk in patients with systemic lupus erythematosus (SLE). The aim of this systematic review and meta-analysis was to assess the strength of the relationship of SLE with fracture risk and the mean difference of bone mineral density (BMD) levels between SLE patients and controls. Literature search was undertaken in multiple indexing databases on September 26, 2015. Studies on the relationship of SLE with fracture risk and the mean difference of BMD levels between SLE patients and controls were included. Data were combined using standard methods of meta-analysis. Twenty-one studies were finally included into the meta-analysis, including 15 studies on the mean difference of BMD levels between SLE patients and controls, and 6 studies were on fracture risk associated with SLE. The meta-analysis showed that SLE patients had significantly lower BMD levels than controls in the whole body (weighted mean difference [WMD] = -0.04; 95 % CI -0.06 to -0.02; P systematic review and meta-analysis provides strong evidence for the relationship of SLE with bone loss and fracture risk.

    Percutaneous vertebroplasty (PVP) and balloon kyphoplasty (BKP) are minimally invasive and effective vertebral augmentation techniques for managing osteoporotic vertebral compression fractures (OVCFs). Recent meta-analyses have compared the incidence of secondary vertebral fractures between patients treated with vertebral augmentation techniques or conservative treatment; however, the inclusions were not thorough and rigorous enough, and the effects of each technique on the incidence of secondary vertebral fractures remain unclear. To perform an updated systematic review and meta-analysis of the studies with more rigorous inclusion criteria on the effects of vertebral augmentation techniques and conservative treatment for OVCF on the incidence of secondary vertebral fractures. PubMed, MEDLINE, EMBASE, SpringerLink, Web of Science, and the Cochrane Library database were searched for relevant original articles comparing the incidence of secondary vertebral fractures between vertebral augmentation techniques and conservative treatment for patients with OVCFs. Randomized controlled trials (RCTs) and prospective non-randomized controlled trials (NRCTs) were identified. The methodological qualities of the studies were evaluated, relevant data were extracted and recorded, and an appropriate meta-analysis was conducted. A total of 13 articles were included. The pooled results from included studies showed no statistically significant differences in the incidence of secondary vertebral fractures between patients treated with vertebral augmentation techniques and conservative treatment. Subgroup analysis comparing different study designs, durations of symptoms, follow-up times, races of patients, and techniques were conducted, and no significant differences in the incidence of secondary fractures were identified (P > 0.05). No obvious publication bias was detected by either Begg's test (P = 0.360 > 0.05) or Egger's test (P = 0.373 > 0.05). Despite current thinking in the

    We aimed to estimate the prevalence of abuse in young children presenting with rib fractures and to identify demographic, injury, and presentation-related characteristics that affect the probability that rib fractures are secondary to abuse. We searched PubMed/MEDLINE and CINAHL databases for articles published in English between January 1, 1990, and June 30, 2014 on rib fracture etiology in children 5 years or younger. Two reviewers independently extracted predefined data elements and assigned quality ratings to included studies. Study-specific abuse prevalences and the sensitivities, specificities, and positive and negative likelihood ratios of patients' demographic and clinical characteristics for abuse were calculated with 95% confidence intervals. Data for 1396 children 48 months or younger with rib fractures were abstracted from 10 articles. Among infants younger than 12 months, abuse prevalence ranged from 67% to 82%, whereas children 12 to 23 and 24 to 35 months old had study-specific abuse prevalences of 29% and 28%, respectively. Age younger than 12 months was the only characteristic significantly associated with increased likelihood of abuse across multiple studies. Rib fracture location was not associated with likelihood of abuse. The retrospective design of the included studies and variations in ascertainment of cases, inclusion/exclusion criteria, and child abuse assessments prevented further meta-analysis. Abuse is the most common cause of rib fractures in infants younger than 12 months. Prospective studies with standardized methods are needed to improve accuracy in determining abuse prevalence among children with rib fractures and characteristics associated with abusive rib fractures.

    The data on the association between coffee consumption and the risk of fractures are inconclusive. We performed a comprehensive literature review and meta-analysis to better quantify this association. We identified all potentially relevant articles by searching MEDLINE, EMBASE, Cochrane Library, Web of Science, SCOPUS, and CINAHL (until February 2013). The keywords "coffee," "caffeine," "drink," and "beverage" were used as the exposure factors, and the keyword "fracture" was used as the outcome factor. We determined the overall relative risk (RR) and confidence interval (CI) for the highest and lowest levels of coffee consumption. A dose-response analysis was performed to assess the risk of fractures based on the level of coffee consumption. We included 253,514 participants with 12,939 fracture cases from 9 cohort and 6 case-control studies. The estimated RR of fractures at the highest level of coffee consumption was 1.14 (95% CI: 1.05-1.24; I(2)=0.0%) in women and 0.76 (95% CI: 0.62-0.94; I(2)=7.3%) in men. In the dose-response analysis, the pooled RRs of fractures in women who consumed 2 and 8 cups of coffee per day were 1.02 (95% CI: 1.01-1.04) and 1.54 (95% CI: 1.19-1.99), respectively. Our meta-analysis suggests that daily consumption of coffee is associated with an increased risk of fractures in women and a contrasting decreased risk in men. However, future well-designed studies should be performed to confirm these findings. Copyright © 2014 Elsevier Inc. All rights reserved.

    The aim of the present study was to evaluate the effect of timing of internal fixation of intracapsular fractures of the neck of femur on the development of late complications, particularly osteonecrosis of femoral head (ONFH) and non-union. We undertook a systematic review of the literature adhering to the PRISMA guidelines. There were 7 eligible reports for the final analysis. The methodological quality of component studies was assessed with the Coleman Methodology Score (CMS). Each included study was assigned a score independently by the two reviewers. The final score of each individual study constituted the average value of the scores given by the two reviewers. The agreement between the two assessors was tested with intraclass correlation coefficient (ICC). The CMS ranged from 37 to 64 within component studies (mean: 46.5, SD: 10.8, median: 41). The ICC was 0.94 (95% CI: 0.69-0.99), implying a nearly perfect agreement between the two assessors. Based on the available data regarding the timing of operative fixation of the femoral neck fractures, 4 discreet pairs of comparison groups could be created: (1) fractures fixed within 6h from injury versus fractures fixed after 6h from injury; (2) fractures fixed within 12h versus after 12h; (3) fractures fixed within 24h versus after 24h; and (4) fractures fixed within 6h versus after 24h. Outcome measures were analyzed within each one of the above pairs of treatment groups. The following subgroups analyses were a priori decided: (1) initial fracture displacement (displaced vs. undisplaced fractures); (2) fixation method (cannulated screws vs. sliding hip screw); (3) quality of reduction (anatomic vs non-anatomic reduction). This study failed to prove any essential association between timing of NOF fracture internal fixation and incidence of AVN. With respect to non-union though, it indicated that delay of internal fixation of more than 24h could increase substantially the odds of non-union. Copyright © 2015 Elsevier

    Fracture sequelae of the proximal humerus poses a complex management decision due to the frequent deformity and its consequences on the peri-articular soft tissues. These patients are frequently elderly with significant medical comorbidities. Due to the age of the patient there is frequently rotator cuff deficiency and therefore the reverse shoulder arthroplasty (RSA) becomes the arthroplasty of choice. We have performed a systematic review of the literature and report nine studies presenting RSA for the treatment of fracture sequelae of the proximal humerus. It is clear that RSA can improve the range of movement and function following proximal humerus fracture sequelae. However, there is a risk of significant complications including dislocation (16.7%), infection (6.7%), intra-operative fracture (3%) and neurological injury (2.6%). There is a need to invest in future prospective comparative studies and randomised trials to further test RSA in fracture sequelae patients. This will provide us with information regarding the longevity of different prosthesis, outcomes and cost-effectiveness of treatment. PMID:28286622

    Low serum 25-hydroxyvitamin D (25(OH)D) levels have been associated with stress fractures in various physically active populations such as the military. To examine the association between serum 25(OH)D levels and stress fractures in the military. Systematic review and meta-analysis. Relevant studies were identified through searching multiple databases and manually screening reference lists. Two reviewers independently selected the included studies by applying the eligibility criteria to the title, abstract, and/or full text of the articles yielded in the search. Two reviewers also independently conducted the methodological quality assessment and data extraction. A random-effects model was used to calculate the mean difference (MD) with 95% CI in serum 25(OH)D levels between stress fracture cases and controls. Nine observational studies on lower extremity stress fractures were eligible, and 1 was excluded due to inadequate data. A total of 2634 military personnel (age, 18-30 years; 44% male) with 761 cases (16% male) and 1873 controls (61% male) from 8 studies were included in the analysis. Three of the 8 studies measured serum 25(OH)D levels at the time of stress fracture diagnosis, and the 5 remaining studies measured serum 25(OH)D levels at the time of entry into basic training. The mean serum 25(OH)D level was lower in stress fracture cases than in controls at the time of entry into basic training (MD, -2.63 ng/mL; 95% CI, -5.80 to 0.54; P = .10; I(2) = 65%) and at the time of stress fracture diagnosis (MD, -2.26 ng/mL; 95% CI, -3.89 to -0.63; P = .007; I(2) = 42%). Despite the inherent limitations of the included studies, the study results suggest some association between low serum 25(OH)D levels and lower extremity stress fractures in military personnel. Given the rigorous training of military personnel, implementing strategies to ensure sufficient 25(OH)D levels may be beneficial for reducing the risk of stress fractures. © 2014 The Author(s).

    Full Text Available Nonunion of femoral neck fractures following primary fixation and neglected femoral neck fracture in young adults is a challenging task. Every effort should be directed toward hip joint salvage in these patients. Among different available options of hip salvage, nonvascularized fibular graft (NVFG osteosynthesis is simple, easy to perform, and a successful technique. In this review, the available literature on NVFG in neglected and nonunion femoral neck fractures has been analyzed. After review of 15 articles on NVFG, the average nonunion rate was estimated to be 7.86% (range 0-31%. Six articles that evaluated the preoperative and postoperative osteonecrosis reported improvement in 50% patients. The clinical and/or functional outcome was good to excellent in 56-96% patients following fibular osteosynthesis. Few complications such as coxa vara deformity, limb shortening, and intraarticular penetration of the graft or hardware have been reported. However, there are minimal donor site morbidities such as mild ankle pain, transient loss of toe flexors and extensors and transient lateral popliteal nerve palsy.

    Full Text Available The valgus-impacted (VI 4-part fractures are a subset of fractures of the proximal humerus with a unique anatomic configuration characterized by a relatively lower incidence of avascular necrosis after operative intervention. We systematically reviewed clinical studies assessing the benefits and harms of least possible fixation techniques (LPFT for this unique fracture type. Such information would be potentially helpful in developing an evidence-based approach in the management of these complex injuries. We performed analytic searches of PubMed, Embase, Web of Science, Google Scholar and the Cochrane Library, restricting it to the years 1991-2014. Included studies had to describe outcomes and complications after primary osteosynthesis with any type of LPFT apart from plate-screws and intramedullary nailing. Eligibility criteria were also included English language, more than 5 cases, minimum follow up of one year and report of clinical outcome using at least one relevant score (Constant, Neer or ASES. Based on 292 database hits we identified 12 eligible studies including 190 four-part valgus impacted fractures in 188 patients. All eligible studies were case series composed of min 8 to max 45 patients per study. The gender distribution was 60% (112 female and 40% (76 male. The average age of the patients at the time of injury was 54.5 years. In 8/12 studies an open reduction was used for fracture fixation using different surgical techniques including KW, cerclage wires, cannulated screws and osteosutures. Closed reduction and percutaneous fixation was used in 4 studies. Mean follow-up time ranged from 24 to 69 months. A good functional outcome (constant score >80 was reported in 9/12 studies. The most common complication was avascular necrosis of the humeral head with an overall incidence of 11% (range, 0-26.3%. Total avascular necrosis (AVN was found in 15/188 patients (7.9% and was more common in percutaneous techniques and partial AVN in 6

    A huge number of risk assessment tools have been developed. Far from all have been validated in external studies, more of them have absence of methodological and transparent evidence, and few are integrated in national guidelines. Therefore, we performed a systematic review to provide an overview of existing valid and reliable risk assessment tools for prediction of osteoporotic fractures. Additionally, we aimed to determine if the performance of each tool was sufficient for practical use, and last, to examine whether the complexity of the tools influenced their discriminative power. We searched PubMed, Embase, and Cochrane databases for papers and evaluated these with respect to methodological quality using the Quality Assessment Tool for Diagnostic Accuracy Studies (QUADAS) checklist. A total of 48 tools were identified; 20 had been externally validated, however, only six tools had been tested more than once in a population-based setting with acceptable methodological quality. None of the tools performed consistently better than the others and simple tools (i.e., the Osteoporosis Self-assessment Tool [OST], Osteoporosis Risk Assessment Instrument [ORAI], and Garvan Fracture Risk Calculator [Garvan]) often did as well or better than more complex tools (i.e., Simple Calculated Risk Estimation Score [SCORE], WHO Fracture Risk Assessment Tool [FRAX], and Qfracture). No studies determined the effectiveness of tools in selecting patients for therapy and thus improving fracture outcomes. High-quality studies in randomized design with population-based cohorts with different case mixes are needed.

    Increased intake or supplementation of vitamin D is often recommended for normal bone health; however, its preventive effect on osteoporosis has not been fully evaluated. The aim of this review is to gather evidence of the efficacy of the optimization of vitamin D nutrition in preventing osteoporosis and osteoporotic fractures. PubMed was used for searching the relevant literature using the MeSH terms "Bone Density (limited to "human", "female", and "English" literature)" or "Fractures (limited to "human", "age ≥45 years", and "English" literature)", and "Vitamin D". The searches yielded 19 randomized controlled trials (RCTs), nine cohort studies, 19 case-control studies, 19 cross-sectional studies, and one meta-analysis. We attempted to answer three questions: 1) does increased vitamin D intake prevent bone loss in peri- and postmenopausal women?, 2) does increased vitamin D intake prevent osteoporotic fractures in the elderly?, and 3) does increased vitamin D in take positively affect peak bone mass attainment in young women? The answer to questions 1 and 2 is that a vitamin D intake of 10-17.5 μg/day (400-700 IU/day) or more is effective in preventing bone loss in late postmenopausal women and an intake of 17.5-20 μg/day (700-800 IU/day) or more together with a calcium supplement reduces the risk of osteoporotic fractures. For question 3, some lines of evidence support the negative effect of low vitamin D nutrition on the attainment of peak bone mass in young women. Further studies are needed to clarify the effect of vitamin D in this age group.

    The late complications following a displaced intra-articular calcaneal fractures includes painful arthrosis for which a subtalar fusion might be considered. In case of malalignment due to loss of height and varus deformity a reconstructive arthrodesis is necessary. The primary aim of the current review study was to assess the functional outcome of the subtalar distraction bone block arthrodesis in the management of late complications of displaced intra-articular calcaneal fractures. The literature was searched for studies in which a subtalar distraction bone block arthrodesis was used in the management of persistent complaints following a displaced intra-articular calcaneal fractures, after its first description in 1988 up to November 1st 2011. The methodological quality of the included studies was assessed using the Coleman Methodology Score. Twenty-one studies reporting on 456 patients were identified. In 93 percent the procedure was a salvage procedures following the late complications of a calcaneal fracture (372 cases). Duration of follow-up ranged from 21 to 108 months (average 40 months). Union rates were reported with an overall average of 96% (range 83-100%). The average modified AOFAS score (maximum 94 points) was 73 points at final follow-up (range 64-83 points). Six studies reported pre- and post-reconstruction AOFAS outcome scores with an average increase of 44.2 points. Wound complications occurred in approximately 6%. With the exception of one study all were level 4 retrospective case series, with an average Coleman Methodology Score of 55 (range 41-79) points. The subtalar distraction bone block arthrodesis is a technically demanding procedure which, in the right hands, provides an overall good result. This is reflected in a significant increase in outcome scores post-operatively. Although most complications are considered minor, there are several pitfalls which should be recognized and avoided.

    The ankylosed spine is prone to fracture after minor trauma due to its changed biomechanical properties. Although many case reports and small series have been published on patients with ankylosing spondylitis (AS) suffering spine fractures, solid data on clinical outcome are rare. In advanced diffuse idiopathic skeletal hyperostosis (DISH), ossification of spinal ligaments also leads to ankylosis. The prevalence of AS is stable, but since DISH may become more widespread due to its association with age, obesity and type 2 diabetes mellitus, a systematic review of the literature was conducted to increase the current knowledge on treatment, neurological status and complications of patients with preexisting ankylosed spines sustaining spinal trauma. A literature search was performed to obtain all relevant articles concerning the outcome of patients with AS or DISH admitted with spinal fractures. Predefined parameters were extracted from the papers and pooled to study the effect of treatment on neurological status and complications. Ninety-three articles were included, representing 345 AS patients and 55 DISH patients. Most fractures were localized in the cervical spine and resulted from low energy impact. Delayed diagnosis often occurred due to patient and doctor related factors. On admission 67.2% of the AS patients and 40.0% of the DISH patients demonstrated neurologic deficits, while secondary neurological deterioration occurred frequently. Surgical or nonoperative treatment did not alter the neurological prospective for most patients. The complication rate was 51.1% in AS patients and 32.7% in DISH patients. The overall mortality within 3 months after injury was 17.7% in AS and 20.0% in DISH. This review suggests that the clinical outcome of patients with fractures in previously ankylosed spines, due to AS or DISH, is considerably worse compared to the general trauma population. Considering the potential increase in prevalence of DISH cases, this condition may

    Objectives: The aim of this systematic review was to compare the diagnostic accuracy, subjective image quality and clinical consequences of 3D-fluoroscopy with standard imaging modalities (2D-fluoroscopy, X-ray or CT) during reduction and fixation of intra-articular upper and lower extremity fractures. Methods: A systematic literature search was performed in MEDLINE, EMBASE and the Cochrane library. In total 673 articles were identified (up to March 2012). The 19 included studies described patients/cadavers with intra-articular upper/lower extremity fractures and compared 3D-fluoroscopy to standard imaging. The study was performed in accordance with the Quality Assessment of Diagnostic Accuracy Studies (QUADAS) guidelines. Diagnostic accuracy was defined by the quality of fracture reduction or implant position and, if possible, expressed as sensitivity and specificity; subjective image quality was determined by the quality of depiction of bone or implants; clinical consequences were defined as corrections in reduction or implant position following 3D-fluoroscopy. Results: Ten cadaver- and nine clinical studies were included. A meta-analysis was not possible, because studies used different scoring protocols to express diagnostic accuracy and reported incomplete data. Based on the individual studies, diagnostic accuracy of 3D-fluoroscopy was better than 2D-fluoroscopy and X-ray, but similar to CT-scanning. Subjective image quality of 3D-fluoroscopy was inferior compared to all other imaging modalities. In 11–40% of the operations additional corrections were performed after 3D-fluoroscopy, while the necessity for these corrections were not recognized based on 2D-fluoroscopic images. Conclusions: Although subjective image quality is rated inferior compared to other imaging modalities, intra-operative use of 3D-fluoroscopy is a helpful diagnostic tool for improving the quality of reduction and implant position in intra-articular fractures.

    Dietary magnesium intake has been related to osteoporosis and risk of fractures in earlier studies; however, findings were conflicting. This meta-analysis indicated that high magnesium intake was not associated with increased risk of fracture; however, a positive marginally significant correlation was found between magnesium intake and bone mineral density (BMD) in total hip as well as in femoral neck. Although there is some evidence on the association between magnesium intake, BMD and fractures, no previous study has summarized findings in this regard. We aimed to systematically review the current evidence on this association and to perform a meta-analysis of observational studies. We searched MEDLINE, Scopus, EMBASE and Google Scholar up to January 2015 for studies that examined the relationship between magnesium intake and BMD or fracture. Studies that had reported correlation coefficients between magnesium intake and BMD or those that reported odds ratios (ORs) or relative risks (RRs) for risk of fracture in different sites were included. In total, 12 studies were included in the meta-analysis. We found that high intakes of magnesium were not significantly associated with risk of total hip fracture (summary effect size 1.92; 95 % CI 0.81, 4.55) or total fractures (1.01; 0.94-1.07). Combining four effect sizes, a positive marginally significant correlation was observed between magnesium intake and total BMD (pooled r 0.16; 95 % CI 0.001, 032). Based on nine effect sizes, we found a marginally significant association between magnesium intake and femoral neck BMD (0.14; 0.001, 0.28). However, no significant correlation was found between magnesium intake and BMD in lumbar spine (0.09; -0.01, 0.19). We found that high intakes of magnesium were not associated with increased risk of hip and total fractures. There was a positive marginally significant correlation between magnesium intake and BMD in femoral neck and total hip. No significant correlations were observed

    Fractures of the radial head and neck are the most common fractures of the elbow, and account for approximately one-third of all elbow fractures. Depending on the fracture type the treatment is either conservative or surgical. There is no absolute consensus regarding optimal treatment for different fracture types. The aim of this protocol is to present the method that will be used to collect, describe and analyse the current evidence regarding the treatment of Mason II-III radial head and neck fractures. We will conduct a systematic review in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocol (PRISMA-P) guidelines statement. We will search a number of databases with a predefined search strategy to collect both randomised and non-randomised studies. The articles will be summarised with descriptive statistics. If applicable a meta-analysis will be conducted. Ethical approval is not required since this is a protocol for a systematic review and no primary data will be collected. The authors will publish findings from this review in a peer-reviewed scientific journal. CRD42016037627. Published by the BMJ Publishing Group Limited.

    Purpose Nowadays, the efficacy of teriparatide in treating osteoporosis was widely accepted, but the discussion about using teriparatide to enhance fracture healing hasn’t come to an agreement. This meta-analysis was conducted to evaluate the effectiveness of teriparatide for fracture healing. Methods We searched PubMed, the Cochrane Library, and Embase in August 2016 for randomized controlled trials (RCTs) which concerned the treatment of teriparatide for fracture healing. Results Finally, a total of 380 patients were randomly assigned in the 5 trials included in this meta-analysis. There was a significant effectiveness with regards to function improvement in patients following fracture, however, there was no significant effectiveness with regards to time of radiographic fracture healing, fracture healing rate and reduction in pain. Conclusions This analysis showed that administration of teriparatide following fracture lacked the effectiveness for fracture healing. Moreover, teriparatide administration had no apparent adverse effects. These results should be interpreted with caution because of some clear limitations. If we want to confirm whether teriparatide improves fracture healing, more high-quality randomized controlled trials are needed. PMID:27997614

    Rib stress fractures (RSFs) are injuries frequently sustained by elite rowers with an injury rate of 8-16% over the course of a rowing career, resulting in negative effects on training and performance. For clinical management, the aim of this review was to describe time to return to sports, summarize potentially preventive measures and appraise the evidence on risk factors. A search strategy was performed in PubMed, SportDiscus, Web of Science and Embase till June 1st 2015. All studies were graded on their quality. The search resulted in 124 studies, of which 17 were included: Ten reported on return to sports, 17 reported on risk factors and nine on preventive measures. For return to sports, nine studies mentioned a loss of training of 4-6 weeks. The shortest period was one week and the longest 16 weeks. For risk factors, insufficient or conflicting evidence was found for changes in the training program, incorrect rowing technique, female gender, low bone mineral density, inadequate equipment, and training type. For prevention, gradual changes in the training program, alertness on the part of coaches and clinicians, and supplementation of diet and hormones are suggested as effective measures. However, no effect studies have been found. The main outcome of this review on RSFs is that little evidence is available on return to sports, risk factors and preventive measures. Coaches and clinicians should carefully guide and assist rowers suffering from RSFs in off training and in the subsequent training period to regain their pre-injury level.

    Full Text Available Abstract Background Spinal fractures are a common source of morbidity in cancer patients. Balloon Kyphoplasty (BKP is a minimally invasive procedure designed to stabilize fractures and correct vertebral deformities. We performed a meta-analysis to determine the efficacy and safety of BKP for spinal fractures in cancer patients. Methods We searched several electronic databases up to September 2008 and the reference lists of relevant publications for studies reporting on BKP in patients with spinal fractures secondary to osteolytic metastasis and multiple myeloma. Outcomes sought included pain relief, functional capacity, quality of life, vertebral height, kyphotic angle and adverse events. Studies were assessed for methodological bias, and estimates of effect were calculated using a random-effects model. Potential reasons for heterogeneity were explored. Results The literature search revealed seven relevant studies published from 2003 to 2008, none of which were randomized trials. Analysis of those studies indicated that BKP resulted in less pain and better functional outcomes, and that these effects were maintained up to 2 years post-procedure. While BKP also improved early vertebral height loss and spinal deformity, these effects were not long-term. No serious procedure-related complications were described. Clinically asymptomatic cement leakage occurred in 6% of all treated levels, and new vertebral fractures in 10% of patients. While there is a lack of studies comparing BKP to other interventions, some data suggested that BKP provided similar pain relief as vertebroplasty and a lower cement leakage rate. Conclusion It appears that there is level III evidence showing BKP is a well-tolerated, relatively safe and effective technique that provides early pain relief and improved functional outcomes in patients with painful neoplastic spinal fractures. BKP also provided long-term benefits in terms of pain and disability. However, the methodological

    To assess the efficacy of comprehensive geriatric assessment (CGA) in prevention of delirium after hip fracture. Systematic review and metaanalysis. Ward based models on geriatrics wards and visiting team based models on orthopaedics wards were included. Four trials (three European, one U.S.; 973 participants) were identified. Two assessed ward-based, and two assessed team-based interventions. MEDLINE, EMBASE, CINAHL and PsycINFO databases; Clinicaltrials.gov; and the Central Register of Controlled Trials were searched. Reference lists from full-text articles were reviewed. Incidence of delirium was the primary outcome. Length of stay, delirium severity, institutionalization, long-term cognition and mortality were predefined secondary outcomes. Duration of delirium was included as a post hoc outcome. There was a significant reduction in delirium overall (relative risk (RR) = 0.81, 95% confidence interval (CI) = 0.69-0.94) in the intervention group. Post hoc subgroup analysis found this effect to be preserved in the team-based intervention group (RR = 0.77, 95% CI = 0.61-0.98) but not the ward-based group. No significant effect was observed on any secondary outcome. There was a reduction in the incidence of delirium after hip fracture with CGA. This is in keeping with results of non-randomized controlled trials and trials in other populations. Team-based interventions appeared superior in contrast to the Ellis CGA paper, but it is likely that heterogeneity in interventions and population studied affected this. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

    Full Text Available Background: Traditionally, conservative treatment of thoracolumbar (TL burst fractures without neurologic deficit has encompassed the application of an extension brace. However, their effectiveness on maintaining the alignment, preventing posttraumatic deformities, and improving back pain, disability and quality of life is doubtful. Objective: The objective was to identify and summarize the evidence from randomized controlled trials (RCTs to determine whether bracing patients who suffer TL fractures adds benefices to the conservative manage without bracing. Materials and Methods: Seven databases were searched for relevant RCTs that compared the clinical and radiological outcomes of orthosis versus no-orthosis for TL burst fractures managed conservatively. Primary outcomes were: (1 Loss of kyphotic angle; (2 failure of conservative management requiring subsequent surgery; and (3 disability and pain outcomes. Secondary outcomes were defined by health-related quality of life and in-hospital stay. Results: Based on predefined inclusion criteria, only two eligible high-quality RCTs with a total of 119 patients were included. No significant difference was identified between the two groups regarding loss of kyphotic angle, pain outcome, or in-hospital stay. The pooled data showed higher scores in physical and mental domains of the Short-Form Health Survey 36 in the group treated without orthosis. Conclusion and Recommendation: The current evidence suggests that orthosis could not be necessary when TL burst fractures without neurologic deficit are treated conservatively. However, due to limitations related with number and size of the included studies, more RCTs with high quality are desirable for making recommendations with more certainty.

    Although there is strong evidence that bisphosphonates prevent certain types of osteoporotic fractures, there are concerns that these medications may be associated with rare atypical femoral fractures (AFF). Recent published studies examining this potential association are conflicting regarding the existence and strength of this association. We conducted a systematic review and meta-analysis of published studies examining the association of bisphosphonates with subtrochanteric, femoral shaft, and AFF. The random-effects model was used to calculate the pooled estimates of adjusted risk ratios (RR). Subgroup analysis was performed by study design, for studies that used validated outcome definitions for AFF, and for studies reporting on duration of bisphosphonate use. Eleven studies were included in the meta-analysis: five case-control and six cohort studies. Bisphosphonate exposure was associated with an increased risk of subtrochanteric, femoral shaft, and AFF, with adjusted RR of 1.70 (95% confidence interval [CI], 1.22-2.37). Subgroup analysis of studies using the American Society for Bone and Mineral Research criteria to define AFF suggests a higher risk of AFF, with bisphosphonate use with RR of 11.78 (95% CI, 0.39-359.69) as compared to studies using mainly diagnosis codes (RR, 1.62; 95% CI, 1.18-2.22), although there is a wide confidence interval and severe heterogeneity (I(2)  = 96.15%) in this subgroup analysis. Subgroup analysis of studies examining at least 5 years of bisphosphonate use showed adjusted RR of 1.62 (95% CI, 1.29-2.04). This meta-analysis suggests there is an increased risk of subtrochanteric, femoral shaft, and AFF among bisphosphonate users. Further research examining the risk of AFF with long-term use of bisphosphonates is indicated as there was limited data in this subgroup. The public health implication of this observed increase in AFF risk is not clear.

    No formal systematic review or meta-analysis was performed up to now to summarize the risk factors of delirium after hip surgery. The present study aimed to quantitatively and comprehensively conclude the risk factors of delirium after hip surgery in elderly patients. A search was applied to CNKI, Embase, Medline, and Cochrane central database (all up to August 2015). All studies assessing the risk factors of delirium after hip surgery in elderly patients without language restriction were reviewed, and qualities of included studies were assessed using the Newcastle-Ottawa Scale. Data were pooled and a meta-analysis was completed. A total of 24 studies were selected, which altogether included 5364 patients with hip fracture. One thousand and ninety of them were cases of delirium occurred after surgery, suggesting the accumulated incidence of 24.0 %. Results of meta-analyses showed that elderly patients with preoperative cognitive impairment [odds ratio (OR) 3.21, 95 % confidence interval (CI) 2.26-4.56), advanced age (standardized mean difference 0.50, 95 % CI 0.33-0.67), living in an institution (OR 2.94; 95 % CI 1.65-5.23), heart failure (OR 2.46; 95 % CI 1.72-3.53), total hip arthroplasty (OR 2.21; 95 % CI 1.16-4.22), multiple comorbidities (OR 1.37; 95 % CI 1.12-1.68) and morphine usage (OR 3.01; 95 % CI 1.30-6.94) were more likely to sustain delirium after hip surgery. Females were less likely to develop delirium after hip surgery (OR 0.83; 95 % CI 0.70-0.98). Related prophylaxis strategies should be implemented in elderly patients involved with above-mentioned risk factors to prevent delirium after hip surgery.

    Full Text Available Background: Risk-adjusted mortality is widely used to benchmark trauma center care. Patients presenting with isolated hip fractures (IHFs are usually excluded from these evaluations. However, there is no standardized definition of an IHF. We aimed to evaluate whether there is consensus on the definition of an IHF used as an exclusion criterion in studies evaluating the performance of trauma centers in terms of mortality. Materials and Methods: We conducted a systematic review of observational studies. We searched the electronic databases MEDLINE, EMBASE, BIOSIS, The Cochrane Library, CINAHL, TRIP Database, and PROQUEST for cohort studies that presented data on mortality to assess the performance of trauma centers and excluded IHF. A standardized, piloted data abstraction form was used to extract data on study settings, IHF definitions and methodological quality of included studies. Consensus was considered to be reached if more than 50% of studies used the same definition of IHF. Results: We identified 8,506 studies of which 11 were eligible for inclusion. Only two studies (18% used the same definition of an IHF. Three (27% used a definition based on Abbreviated Injury Scale (AIS Codes and five (45% on International Classification of Diseases (ICD codes. Four (36% studies had inclusion criteria based on age, five (45% on secondary injuries, and four (36% on the mechanism of injury. Eight studies (73% had good overall methodological quality. Conclusions: We observed important heterogeneity in the definition of an IHF used as an exclusion criterion in studies evaluating the performance of trauma centers. Consensus on a standardized definition is needed to improve the validity of evaluations of the quality of trauma care.

    Long bone fractures (LBFs) are among the most frequent traumatic injuries seen in emergency departments. Reduction and immobilization is the most common form of treatment for displaced fractures. Point-of-care ultrasound (PoCUS) is a promising technique for diagnosing LBFs and assessing the success of reduction attempts. This article offers a comprehensive review of the use of PoCUS for the diagnosis and reduction of LBFs. Data source MEDLINE and EMBASE databases were searched through July 19, 2015. Study selection We included prospective studies that assessed test characteristics of PoCUS in 1) the diagnosis or 2) the reduction of LBFs. The methodological quality of the included studies was evaluated using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool. Data extraction Thirty studies met inclusion criteria (n=3,506; overall fracture rate 48.0%). Test characteristics of PoCUS for the diagnosis of LBFs were as follows: sensitivity 64.7%-100%, specificity 79.2%-100%, positive likelihood ratio (LR) 3.11-infinity, and negative LR zero-0.45. Sensitivity and specificity for the adequate reduction of LBFs with PoCUS were 94%-100% and 56%-100%, respectively. PoCUS diagnosis of pediatric forearm fractures in 10 studies showed a pooled sensitivity of 93.1% (95% confidence interval [CI], 87.2%-96.4%) and specificity of 92.9% (95% CI, 86.6%-96.4%), and PoCUS diagnosis of adult ankle fractures in four studies showed a pooled sensitivity of 89.5% (95% CI, 77.0%-95.6%) and specificity of 94.2% (95% CI, 86.1%-97.7%). PoCUS demonstrates good diagnostic accuracy in all LBFs studied, especially in pooled results of diagnosis of pediatric forearm and adult ankle fractures. PoCUS is an appropriate adjunct to plain radiographs for LBFs.

    This systematic review aimed to examine the evidence for teriparatide in Asia for osteoporosis with a high fracture risk and for exploratory (unapproved) bone-related indications. MEDLINE (1946+), EMBASE (1966+), and ClinicalTrials.gov (2008+) were searched (16 August 2013); all studies of daily subcutaneous teriparatide 20 μg for bone-related conditions from China, Hong Kong, Japan, Republic of Korea, Philippines, Singapore, and Taiwan were included. Evidence on efficacy/safety was retrieved primarily from randomized controlled trials (10 publications) of postmenopausal women from Japan and China. In these studies, teriparatide was well tolerated; subjects had significantly greater increases in lumbar spine bone mineral density (BMD) from baseline compared with placebo, antiresorptive agents, or elcatonin/calcitonin; bone turnover markers increased from baseline and were sustained at elevated levels during teriparatide treatment. Few studies reported fracture risk, pain, or quality of life; one study showed a lower incidence of new-onset vertebral fracture with teriparatide versus antiresorptive agents. Nonrandomized studies (nine publications, one unpublished trial) conducted mainly in Taiwan, Japan, and the Republic of Korea provided supporting data for efficacy. The exploratory (unapproved) use of teriparatide (17 publications) for fracture healing and osteonecrosis of the jaw was described primarily in case reports. The clinical effectiveness of teriparatide for treatment of postmenopausal women with osteoporosis who are at high risk of fracture in Asia is focused primarily on improvements in BMD and tolerability. Recommended additional studies may include assessment of fracture risk and the effect of teriparatide on pain, quality of life, and mortality in Asia.

    Review the literature concerning modalities to evaluate the integrity of the deltoid ligament in patients with supination external rotation ankle fractures. The electronic databases Pubmed/Medline, CINAHL and Embase were searched from 1987 to November 2007 to identify all published original studies concerning diagnostic modalities to evaluate the integrity of the deltoid ligament in adult ankle fractures. This review included nine studies involving 423 ankle fractures. Three trails investigated medial tenderness; two studies, ecchymosis; two studies, swelling; one study, an injury radiograph; six studies, a type of radiographic stress view; one study, the Lauge-Hansen classification; one study, MRI; and one article studied arthroscopy in the evaluation of the deltoid ligament integrity. Swelling, ecchymosis, medial tenderness, initial injury radiographs and the Lauge-Hansen classification are less adequate predictors of the integrity of the deltoid ligament. Manual or the less painful variant, the gravity external rotation stress radiographs are considered the gold standard. The amount of medial clear space widening indicative of a positive external rotation stress test has been somewhat variable in the literature but > or =5 mm is generally regarded as most reliable. Achieving adequate external rotation of the foot when obtaining stress radiographs is more important than positioning the ankle in the appropriate degree of ankle flexion. The amount of applied force necessary when performing an external rotation stress radiograph is not well defined and mainly determined by the patient's pain level. The indication for surgery should not be based on the absolute value of one parameter but on the combination of several parameters. If nonoperative treatment is chosen despite a positive stress radiograph, close follow-up is critical because subluxation of the ankle joint is still possible. MRI could be useful in individual cases.

    Thoracolumbar spine injuries are commonly encountered in patients with trauma, accounting for almost 90% of all spinal fractures. Thoracolumbar burst fractures comprise a high percentage of these traumatic fractures (45%), and approximately half of the patients with this injury pattern are neurologically intact. However, a debate over complication rates associated with operative versus nonoperative management of various thoracolumbar fracture morphologies is ongoing, particularly concerning those patients presenting without a neurological deficit. A MEDLINE search for pertinent literature published between 1966 and December 2013 was conducted by 2 authors (G.G. and R.D.), who used 2 broad search terms to maximize the initial pool of manuscripts for screening. These terms were "operative lumbar spine adverse events" and "nonoperative lumbar spine adverse events." In an advanced MEDLINE search of the term "operative lumbar spine adverse events" on January 8, 2014, 1459 results were obtained. In a search of "nonoperative lumbar spine adverse events," 150 results were obtained. After a review of all abstracts for relevance to traumatic thoracolumbar spinal injuries, 62 abstracts were reviewed for the "operative" group and 21 abstracts were reviewed for the "nonoperative" group. A total of 14 manuscripts that met inclusion criteria for the operative group and 5 manuscripts that met criteria for the nonoperative group were included. There were a total of 919 and 436 patients in the operative and nonoperative treatment groups, respectively. There were no statistically significant differences between the groups with respect to age, sex, and length of stay. The mean ages were 43.17 years in the operative and 34.68 years in the nonoperative groups. The majority of patients in both groups were Frankel Grade E (342 and 319 in operative and nonoperative groups, respectively). Among the studies that reported the data, the mean length of stay was 14 days in the operative group

    Systematic reviews, a cornerstone of evidence-based medicine, are not produced quickly enough to support clinical practice. The cost of production, availability of the requisite expertise and timeliness are often quoted as major contributors for the delay. This detailed survey of the state of the art of information systems designed to support or automate individual tasks in the systematic review, and in particular systematic reviews of randomized controlled clinical trials, reveals trends that see the convergence of several parallel research projects. We surveyed literature describing informatics systems that support or automate the processes of systematic review or each of the tasks of the systematic review. Several projects focus on automating, simplifying and/or streamlining specific tasks of the systematic review. Some tasks are already fully automated while others are still largely manual. In this review, we describe each task and the effect that its automation would have on the entire systematic review process, summarize the existing information system support for each task, and highlight where further research is needed for realizing automation for the task. Integration of the systems that automate systematic review tasks may lead to a revised systematic review workflow. We envisage the optimized workflow will lead to system in which each systematic review is described as a computer program that automatically retrieves relevant trials, appraises them, extracts and synthesizes data, evaluates the risk of bias, performs meta-analysis calculations, and produces a report in real time.

    Full Text Available Surgical and non-surgical interventions are the two categories for treatment of vertebral compression fractures (VCFs. However, there is clinical uncertainty over optimal management. This study aimed to examine the safety and effectiveness of surgical management for treatment of VCFs with osteopenia compared with non-surgical treatment.We conducted a systematic search through electronic databases from inception to June 2014, with no limits on study data or language. Randomized controlled trials (RCTs evaluating surgical versus non-surgical interventions for treatment of patients with VCFs due to osteopenia were considered. Primary outcomes were pain and adverse effects. A random-effects model was used to calculate the pooled mean difference (MD or risk ratios with 95% confidence interval (CI.Sixteen reports (11 studies met the inclusion criteria, and provided data for the meta-analysis with a total of 1,401 participants. Compared with conservative treatment, surgical treatment was more effective in reducing pain (short-term: MD -2.05, 95% CI -3.55 to -0.56, P=0.007; mid-term: MD -1.70, 95% CI -2.78 to -0.62, P=0.002; long-term: MD -1.24, 95% CI -2.20 to -0.29, P=0.01 and disability on the Roland-Morris Disability score (short-term: MD -4.97, 95% CI -8.71 to -1.23, P=0.009, as well as improving quality of life on the Short-Form 36 Physical Component Summary score (short-term: MD 5.53, 95% CI 1.45 to 9.61, P=0.008 and the Quality of Life Questionnaire of the European Foundation for Osteoporosis score (short-term: MD -5.01, 95% CI -8.11 to -1.91, P=0.002. Indirect comparisons between vertebroplasty and kyphoplasty found no evidence that the treatment effect differed across the two interventions for any outcomes assessed. Compared with the sham procedure, surgical treatment showed no evidence of improvement in pain relief and physical function. Based on these two comparisons, no significant difference between groups was noted in the pooled results

    Evidence-based medicine (EBM) aims to combine the best available scientific evidence with clinical experience and individual judgment of patient needs. In the hierarchy of scientific evidence, systematic reviews (along with meta-analyses) occupy the highest levels in terms of the quality of evidence. A systematic review is the process of searching, selecting, appraising, synthesising and reporting clinical evidence on a particular question or topic. It is currently considered the best, least biased and most rational way to organise, gather, evaluate and integrate scientific evidence from the rapidly-changing medical and healthcare literature. Systematic reviews could be used to present current concepts or serve as review articles and replace the traditional expert opinion or narrative review. This article explains the structure and content of a systematic review.

    Introduction: Modified Stoppa approach was introduced as an alternative to ilioinguinal approach for management of anterior fractures of acetabulum in order to reduce complications of the latter. However, the efficacy of either approach over other is not well established. The aim of this meta-analysis is to compare the efficacy of modified stoppa and ilioinguinal approach in the management of acetabular fractures in terms of a) quality of reduction achieved b) complication rates c) functional outcomes d) operative time e) intra-operative blood loss. Methods: Databases of PubMed, EMBASE and Cochrane registry of controlled trials were taken into consideration for studies on modified Stoppa approach versus Ilioinguinal approach group for the treatment of anterior acetabular fractures. Dichotomous variables were presented as risk ratios (RRs) /Odds Ratio (OR) with 95% confidence intervals (CIs), and continuous data was measured as mean differences, with 95% CIs. Result: Four studies involving 375 patients were included in this meta-analysis. Out of those 375 patients, 192 were managed with ilioinguinal approach and 183 were managed with modified Stoppa approach. Anatomical reduction was significantly higher in Stoppa group (p=0.052, RR=1. 19 (1.02, 1.37), p=0. 90, I2=0%). The complication rate was significantly higher in the Ilioinguinal approach as compared with the Stoppa approach (p=0.01, RR 0.63 (0.44 to 0.91), p=0.73 (I2= 0%). The operative time was significantly shorter with modified Stoppa approach (MD = -48.79 (-80.29 to -17.30), p=0.002). No significant differences were found between the two groups in terms of their functional outcomes (p=0.63, RR 0.96 (-0.80 to 1.15), p=0. 56, I2=0%) and blood loss (MD= -212.89 (-476.27 to 50.49) p=0. 06, I2=71%). Conclusion: Anterior acetabular fractures, if operated with the modified Stoppa approach were found to have better reduction and lower complication rates with less operative time, when compared to ilioinguinal

    Since its introduction by the Nuremberg Code and the Declaration of Helsinki, the place held by ethics in biomedical research has been continuously increasing in importance. The past 30 years have also seen exponential growth in the number of biomedical articles published. A systematic review of the literature is the scientific way of synthesising a plethora of information, by exhaustively searching out and objectively analysing the studies dealing with a given issue. However, the question of ethics in systematic reviews is rarely touched upon. This could lead to some drawbacks, as systematic reviews may contain studies with ethical insufficiencies, may be a possible way to publish unethical research and may also be prone to conflict of interest. Finally, informed consent given for an original study is not necessarily still valid at the systematic review level. There is no doubt that routine ethical assessment in systematic reviews would help to improve the ethical and methodological quality of studies in general. However, ethical issues change so much with time and location, and are so broad in scope and in context that it appears illusory to search for a universal, internationally accepted standard for ethical assessment in systematic reviews. Some simple suggestions could nevertheless be drawn from the present reflection and are discussed in the paper.

    The purpose of this research was to compare the efficacy and safety of unilateral versus bilateral PKP for osteoporotic vertebral compression fractures (OVCFs). Six databases (Cochrane, PubMed, MEDLINE, EMBASE, SinoMed, and CNKI) were searched without language restrictions. Twelve randomized controlled trials involving a total of 1,030 patients were identified. The results indicate that unilateral PKP had a better degree of pain relief (visual analog scale) than bilateral PKP (p = 0.04; 95%CI = -0.36 to -0.00) with short-term follow-up (within 4 weeks) after operation. The radiological outcome assessment with short-term follow-up after operation indicates bilateral PKP had a better degree of anterior vertebral height restoration (p = 0.03; 95%CI = -2.58 to -0.14). Operation time and cement dosage were less for unilateral PKP (p < 0.05). There were no differences in complications such as cement leakage and adjacent vertebral fractures between two approaches (p = 0.06 and p = 0.97, respectively). Life quality assessment (SF-36) indicates unilateral PKP had a better result of bodily pain relief (p < 0.05; 95%CI = 3.93 to 7.48) and general health benefit (p < 0.05; 95%CI = 0.02 to 2.93) with short-term follow-up after operation. We suggest that a unilateral PKP is advantageous.

    After more than two decades the treatment effect of cement augmentation of osteoporotic vertebral compression fractures (VCF) has now been questioned by two blinded randomised placebo-controlled trials. Thus many practitioners are uncertain on the recommendation for cement augmentation techniques in elderly patients with osteoporotic VCF. This systematic review analyses randomised controlled trials on vertebroplasty and kyphoplasty to provide an overview on the current evidence. From an electronic database research 8 studies could be identified meeting our inclusion criteria of osteoporotic VCF in elderly (age>60 years), treatment with vertebroplasty or kyphoplasty, controlled with placebo or standard medical therapy, quality of life, function, or pain as primary parameter, and randomisation. Only two studies were properly blinded using a sham-operation as control. The other studies were using a non-surgical treatment control group. Further possible bias may be caused by manufacturer involvement in financing of three published RCT. There is level Ib evidence that vertebroplasty is no better than placebo, which is conflicting with the available level IIb evidence that there is a positive short-term effect of cement augmentation compared to standard medical therapy with regard to QoL, function and pain. Kyphoplasty is not superior to vertebroplasty with regard to pain, but with regard to VCF reduction (evidence level IIb). Kyphoplasty is probably not cost-effective (evidence level IIb), and vertebroplasty has not more than short-term cost-effectiveness (evidence level IV). Vertebroplasty and kyphoplasty cannot be recommended as standard treatment for osteoporotic VCF. Ongoing sham-controlled trials may provide further evidence in this regard.

    Full Text Available Abstract Background There is a large quality of care gap for patients with osteoporosis. As a fragility fracture is a strong indicator of underlying osteoporosis, it offers an ideal opportunity to initiate investigation and treatment. However, studies of post-fracture populations document screening and treatment rates below 20% in most settings. This is despite the fact that bone mineral density (BMD scans are effective at identifying patients at high risk of fracture, and effective drug treatments are widely available. Effective interventions are required to remedy this incongruity in current practice. Methods This study reviewed randomised controlled trials (RCT involving fully qualified healthcare professionals caring for patients with a fragility fracture in all healthcare settings. Any intervention designed to modify the behaviour of healthcare professionals or implement a service delivery change was considered. The main outcomes were BMD scanning and osteoporosis treatment with anti-resorptive therapy. The electronic databases Medline and Embase were searched from 1994 to June 2010 to identify relevant articles in English. Post-intervention risk differences (RDs were calculated for the main outcomes and any additional study primary outcomes; the trials were meta-analysed.

    Objective To systematically review the published articles available on management for the displaced acetabular fractures. Methods MEDLINE, EMBASE, CBM and Cochrane Database were searched for the articles on management of displaced acetabular fractures in the past 40 years. Manual searches of the bibliographic sections of electronically identified papers were done to identify further papers. Meticulous data extraction and meta-analysis were performed according to preset protocol. Results Of 869 citations initially identified, 72 papers which involved a total of 6509 patients with 6549 acetabular fractures met all eligibility criteria. Reduction was anatomical or good in 87.6% of the patients, and poor in 13.0%. An incidence of iatrogenic nerve palsy was 6.0%. Deep venous thrombosis (DVT) and pulmonary embolism (PE) had an overall incidence of 3.9%. The incidence of local wound infections was 4. 2%. The heterotopic ossifi-cation (HO) was seen in 26.9% of the patients. The overall incidence of osteoarthritis (OA) was 18.0%. The score to assess the functional results, 46.6% of the patients were graded as excellent, 32.4% as good, 11.6% as fair, and 9. 5% as poor. Using the Harris Hip Score (HHS), 48.4% of the patients had an ex-cellent result, 26.9% were graded as good, 10.7% as fair, and 14.0% as poor. 85.5% of the patients with satisfactory reduction had an excellent or good functional result, while 63.7% of the patients without satis-factory reduction did. The most common cause was road traffic accident. The most common fracture types were fractures of the posterior wall and both columns as well as transverse ones associated with posterior wall. Conclusions Operative management of displaced acetabular fractures can have satisfactory functional out-comes. Reduction quality may be the major influence on functional outcome. The most common long-term complications are osteoarthritis and heterotopic ossification.%目的 采用循证医学研究方法,系统评价移位

    Dental adhesives are usually tested in shear or tension even though neither of these approaches measures the local stress triggering failure. Because the stress level varies extensively over the bonded surface, it seems as a fracture mechanics approach would be more appropriate. In this review different general aspects of fracture mechanics and adhesive joints were reviewed first. That review served as a foundation for a review of fracture toughness studies performed on dental adhesives. The dental adhesive studies were identified through a MEDLINE search using "dental adhesion testing AND enamel OR dentin AND fracture toughness" as search strategy. The outcome of the review revealed that fracture toughness studies performed on dental adhesives are complex, both regarding technical performance as well as achieving good discriminating ability between different adhesives. The review also suggested that most fracture toughness tests of adhesives performed in dentistry are not totally reliable because they usually did not consider the complex stress pattern at the adhesive interface. However, despite these limitations, the review strongly supports the notion that the proper way of studying dental adhesion is by use a fracture mechanics. At the present time, it seems as the fracture energy of adhesives might be more appropriate to determine than their fracture toughness values. Copyright 2009 Academy of Dental Materials.

    Rib fractures can cause significant problems in trauma patients, often resulting in pain and difficulty with respiration. To prevent pulmonary complications and decrease the morbidity and mortality rates of patients with rib fractures, currently there is a trend to provide surgical management of patients with flail chest. However, the indications for rib fracture fixation require further specification. Past and current strategies are described according to a review of the medical literature. A systematic review was performed including current indications for rib fracture fixation. MEDLINE (2000-2013) was searched, as well as Embase (2000-2013) and Cochrane Databases, using the keywords rib, fracture, fixation, plate, repair, and surgery. Three retrospective studies were found that described different techniques for rib fracture fixation. The results demonstrated a reduced number of ventilation days, decreased long-term morbidity and pain, and satisfactory rehabilitation after surgical treatment. In addition to flail chest, age, Injury Severity Score, and the number of rib fractures were important predictive factors for morbidity and mortality. Surgical rib fracture fixation might be indicated in a broader range of cases than is currently performed. Prospective randomized trials are needed for further confirmation. © The Finnish Surgical Society 2014.

    The number of systematic reviews published in the orthopaedic literature has increased, and these reviews can help guide clinical decision making. However, the quality of these reviews can affect the reader's ability to use the data to arrive at accurate conclusions and make clinical decisions. To evaluate the methodological and reporting quality of systematic reviews and meta-analyses in the sports medicine literature to determine whether such reviews should be used to guide treatment decisions. The hypothesis was that many systematic reviews in the orthopaedic sports medicine literature may not follow the appropriate reporting guidelines or methodological criteria recommended for systematic reviews. Systematic review. All clinical sports medicine systematic reviews and meta-analyses from 2009 to 2013 published in The American Journal of Sports Medicine (AJSM), The Journal of Bone and Joint Surgery (JBJS), Arthroscopy, Sports Health, and Knee Surgery, Sports Traumatology, Arthroscopy (KSSTA) were reviewed and evaluated for level of evidence according to the guidelines from the Oxford Centre for Evidence-Based Medicine, for reporting quality according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, and for methodological quality according to the Assessment of Multiple Systematic Reviews (AMSTAR) tool. Analysis was performed by year and journal of publication, and the levels of evidence included in the systematic reviews were also analyzed. A total of 200 systematic reviews and meta-analyses were identified over the study period. Of these, 53% included evidence levels 4 and 5 in their analyses, with just 32% including evidence levels 1 and 2 only. There were significant differences in the proportion of articles with high levels of evidence (P Sports Health and KSSTA on the PRISMA and AMSTAR.

  13. Reading, writing and systematic review

    2008-01-01

    Aim This paper offers a discussion of the reading and writing practices that define systematic review. Background Although increasingly popular, systematic review has engendered a critique of the claims made for it as a more objective method for summing up research findings than other kinds of reviews. Discussion An alternative understanding of systematic review is as a highly subjective, albeit disciplined, engagement between resisting readers and resistant texts. Reviewers of research exemplify the resisting reader when they exclude reports on grounds of relevance, quality, or methodological difference. Research reports exemplify resistant texts as they do not simply yield their findings, but rather must be made docile to review. These acts of resistance make systematic review possible, but challenge claims of its greater capacity to control bias. Conclusion An understanding of the reading and writing practices that define systematic review still holds truth and objectivity as regulative ideals, but is aware of the reading and writing practices that both enable and challenge those ideals.

    Full Text Available The question which kind of methods is most suitable for treating the old people for osteoporotic vertebral compression fracture is still discussed and pairwise meta-analyses cannot get hierarchies of these treatments. Our aim is to integrate the evidence to provide hierarchies of the comparative efficacy measured by the change of VAS (Visual Analogue Scale and tolerability measured by incidence of new fractures and risk of all-cause discontinuation on three treatments (percutaneous vertebroplasty (PVP、balloon kyphoplasty (BK and conservative treatment (CT.We performed a Bayesian-framework network meta-analysis of randomized controlled trials (RCTs to compare three treatments for the old people with osteoporotic vertebral compression fracture. The eligible RCTs were identified by searching Amed, British Nursing Index, Embase, Pubmed, the Cochrane Central Register of Controlled Trials (CENTRAL, Google scholar, SIGLE, the National Technical Information Service, the National Research Register (UK and the Current Controlled Trials databases. Data from three outcomes (e.g. VAS, risk of all-cause discontinuation and incidence of new fractures were independently extracted by two authors.A total of five RCTs were finally included into this article. PVP and BK significantly decreased VAS when compared with CT. BK had a significantly lower risk of all-cause discontinuation contrast to CT. Three treatments (BK, PVP and CT had no significant differences in the incidence of new fractures.PVP may be the best way to relieve pain, CT might lead to the lowest incidence of new fractures and BK might had the lowest risk of all-cause discontinuation in old people with osteoporotic vertebral compression fracture. More large-scale and longer duration of follow-up studies are needed.

    The need for robust evidence to support conservation actions has driven the adoption of systematic approaches to research synthesis in ecology. However, applying systematic review to complex or open questions remains challenging, and this task is becoming more difficult as the quantity of scientific literature increases. We drew on the science of linguistics for guidance as to why the process of identifying and sorting information during systematic review remains so labor intensive, and to provide potential solutions. Several linguistic properties of peer-reviewed corpora-including nonrandom selection of review topics, small-world properties of semantic networks, and spatiotemporal variation in word meaning-greatly increase the effort needed to complete the systematic review process. Conversely, the resolution of these semantic complexities is a common motivation for narrative reviews, but this process is rarely enacted with the rigor applied during linguistic analysis. Therefore, linguistics provides a unifying framework for understanding some key challenges of systematic review and highlights 2 useful directions for future research. First, in cases where semantic complexity generates barriers to synthesis, ecologists should consider drawing on existing methods-such as natural language processing or the construction of research thesauri and ontologies-that provide tools for mapping and resolving that complexity. These tools could help individual researchers classify research material in a more robust manner and provide valuable guidance for future researchers on that topic. Second, a linguistic perspective highlights that scientific writing is a rich resource worthy of detailed study, an observation that can sometimes be lost during the search for data during systematic review or meta-analysis. For example, mapping semantic networks can reveal redundancy and complementarity among scientific concepts, leading to new insights and research questions. Consequently

    This study is a literature review about Iridology/Irisdiagnose in the period from 1970 to 2005. The objective was to identify the worldwide scientific publications (articles) in this field and the opinions about the method. Twenty-five articles were found, four of them from Brazilian authors. About the category, 1 was literature review, 12 research studies and 12 updates, historical reviews or editorials. The countries that have contributed more with the studies were Brazil and Russia. Fifteen of those are in favor of the method and 10 are against it. In conclusion, it is necessary to develop more studies inside the methodological rigor, once Iridology brings hope to preventive medicine.

    To compare the clinical efficacy and complications of limited internal fixation combined with external fixation (LIFEF) and open reduction and internal fixation (ORIF) in the treatment of Pilon fracture. We searched databases including Pubmed, Embase, Web of science, Cochrane Library and China Biology Medicine disc for the studies comparing clinical efficacy and complications of LIFEF and ORIF in the treatment of Pilon fracture. The clinical efficacy was evaluated by the rate of nonunion, malunion/delayed union and the excellent/good rate assessed by Mazur ankle score. The complications including infections and arthritis symptoms after surgery were also investigated. Nine trials including 498 pilon fractures of 494 patients were identified. The meta-analysis found no significant differences in nonunion rate (RR = 1.60, 95% CI: 0.66 to 3.86, p = 0.30), and the excellent/good rate (RR = 0.95, 95% CI: 0.86 to 1.04, p = 0.28) between LIFEF group and ORIF group. For assessment of infections, there were significant differences in the rate of deep infection (RR = 2.18, 95% CI: 1.34 to 3.55, p = 0.002), and the rate of arthritis (RR = 1.26, 95% CI: 1.03 to 1.53, p = 0.02) between LIFEF group and ORIF group. LIFEF has similar effect as ORIF in the treatment of pilon fractures, however, LIFEF group has significantly higher risk of complications than ORIF group does. So LIFEF is not recommended in the treatment of pilon fracture. Copyright © 2017 Daping Hospital and the Research Institute of Surgery of the Third Military Medical University.

    Ankle fractures are common injuries that require meticulous technique in order to optimise outcome. The Lauge-Hansen and Danis-Weber classifications in addition to careful evaluation of the injury mechanism can help guide treatment but surgeons must be aware that there are injury patterns that will not always fit the afore mentioned patterns. The principles of atraumatic soft tissue handling, rigid internal fixation and early range of motion exercises are critical for successfully treating these injuries. There are still areas of treatment uncertainty and future directed research is needed in order to address some of these questions.

    Several authors have recently emphasized the role of magnetic resonance imaging (MRI) in the diagnosis of subchondral fractures. There is increasing interest about this type of fractures, mostly because they have been implicated in the genesis of some well-known destructive articular conditions whose cause was previously undetermined, such as distal clavicular osteolysis, rapidly progressive osteoarthritis of the hip, spontaneous osteonecrosis of the knee and adult-type Freiberg's infraction. Subchondral fractures may ultimately lead to bone collapse, secondary osteonecrosis and severe articular damage, and there may be rapid progression of joint destruction over a period of weeks to months. It has been suggested that timely diagnosis might potentially improve the outcome and avoid the onset of destructive joint disease, making MRI even more important in this setting. The fracture line usually appears as a band of low signal intensity in the subchondral bone plate, adjacent to the articular surface, most often surrounded by bone marrow edema. In this article the authors review the most relevant imaging features of subchondral fractures in several joints, stressing the importance of early recognition for a better outcome. (orig.)

    Full Text Available Vitamin D deficiency is a relevant problem particularly in south Europe and in over 65 year old subjects, that is often underestimated. Vitamin D deficiency represents a real medical emergency also for its role in the patho-physiology of muscular-skeletal diseases. Chronic vitamin D deficiency leads to severe bone and muscular outcomes including: osteoporosis, osteomalacia and proximal limb myopathy. These increase the risk of falling and fractures. The efficacy of vitamin D treatment in decreasing the fracture risk has been reporting in several studies. The negative results of some recent studies questioned the clinical vitamin D efficacy. However these studies have a number of methodological problems and even the interpretation of the results is questionable. In this paper we review all these aspects. This analysis permits to confirm that vitamin D treatment can be extremely cost-effective when given to people at high risk of deficiency. An acceptable compliance is obviously of critical importance.

    Objectives This systematic review identifies and reviews both peer-reviewed and 'grey' literature, across a range of disciplines and from diverse sources, relating to the condition of children living in mountain communities in low- and middle-income countries. Findings The literature on poverty in these communities does not generally focus on the particular vulnerabilities of children or the impact of intersecting vulnerabilities on the most marginalised members of communities. However, this literature does contribute analyses of the broader context and variety of factors impacting on human development in mountainous areas. The literature on other areas of children's lives-health, nutrition, child mortality, education, and child labour-focuses more specifically on children's particular vulnerabilities or experiences. However, it sometimes lacks the broader analysis of the many interrelated characteristics of a mountainous environment which impact on children's situations. Themes Nevertheless, certain themes recur across many disciplines and types of literature, and point to some general conclusions: mountain poverty is influenced by the very local specificities of the physical environment; mountain communities are often politically and economically marginalised, particularly for the most vulnerable within these communities, including children; and mountain communities themselves are an important locus for challenging and interrupting cycles of increasing inequality and disadvantage. While this broad-scale review represents a modest first step, its findings provide the basis for further investigation.

    Osteoporosis is the most common metabolic bone disease; vertebral fractures are the most common osteoporotic fractures. Several radiological scoring methods using different criteria for osteoporotic vertebral fractures exist. Quantitative morphometry (QM) uses ratios derived from direct vertebral body height measurements to define fractures. Semi-quantitative (SQ) visual grading is performed according to height and area reduction. The algorithm-based qualitative (ABQ) method introduced a scheme to systematically rule out non-fracture deformities and diagnoses osteoporotic vertebral fractures based on endplate depression. The concordance across methods is currently a matter of debate. This article reviews the most commonly applied standardised radiographic scoring methods for osteoporotic vertebral fractures, attaining an impartial perspective of benefits and limitations. It provides image examples and discusses aspects that facilitate large-scale application, such as automated image analysis software and different imaging investigations. It also reviews the implications of different fracture definitions for scientific research and clinical practice. Accurate standardised scoring methods for assessing osteoporotic vertebral fractures are crucial, considering that differences in definition will have implications for patient care and scientific research. Evaluation of the feasibility and concordance among methods will allow establishing their benefits and limitations, and most importantly, optimise their effectiveness for widespread application.

    Androgen deprivation therapy (ADT) is an effective treatment for men with advanced prostate cancer, but loss of bone mineral density (BMD) is a major risk factor for fractures. This analysis evaluated the relative effectiveness of osteoporosis treatments using BMD as a surrogate endpoint for fragility fractures in men on continuous ADT. We included randomized controlled trials studying bisphosphonates, denosumab, toremifene, and raloxifene in patients with non-metastatic prostate cancer on ADT for review. Primary outcomes included percentage change in BMD from baseline at total hip, lumbar spine and femoral neck sites. We also recorded incidence rates of any fractures. Network meta-analysis was done to evaluate change in BMD. Out of 270 identified articles, 13 RCTs were included for analysis. The largest BMD improvement compared to placebo at 12 months for total hip site was: raloxifene 3.70% (95% credible interval [CrI], 1.48-5.92%), lumbar spine: zoledronic acid 6.96% (CrI:-5.34-8.52%) and femoral neck: risedronate 6.77% (CrI:-6.87-20.27%). Two studies reported fractures as outcome measure. Toremifene and denosumab studies reported improved incidence of new vertebral fracture outcome vs placebo (2.5% vs 4.9%; p<0.05 and 1.0% vs 3.3%; p=0.004, respectively) at 2-year timepoint. Denosumab and zoledronic acid may have stronger evidence, but all treatments are effective in reducing the rate of bone loss in our patient population. The key policy implication is that men who are at risk for fracture should receive some form of osteoporosis treatment. Choosing the optimal drug should be based on efficacy, safety, product availability, patient preferences and costs. This article is protected by copyright. All rights reserved.

    Clozapine is exceptionally effective in psychotic disorders and can reduce suicidal risk. Nevertheless, its use is limited due to potentially life-threatening adverse effects, including myocarditis and cardiomyopathy. Given their clinical importance, we systematically reviewed research on adverse cardiac effects of clozapine, aiming to improve estimates of their incidence, summarize features supporting their diagnosis, and evaluate proposed monitoring procedures. Incidence of early (≤2 months) myocarditis ranges from <0.1 to 1.0 % and later (3-12 months) cardiomyopathy about 10 times less. Diagnosis rests on relatively nonspecific symptoms, ECG changes, elevated indices of myocardial damage, cardiac MRI findings, and importantly, echocardiographic evidence of developing ventricular failure. Treatment involves stopping clozapine and empirical applications of steroids, diuretics, beta-blockers, and antiangiotensin agents. Mortality averages approximately 25 %. Safety of clozapine reuse remains uncertain. Systematic studies are needed to improve knowledge of the epidemiology, avoidance, early identification, and treatment of these adverse effects, with effective and practicable monitoring protocols.

  15. A clinician's guide to systematic reviews.

    Science.gov (United States)

    Crowther, David M

    2013-08-01

    The purpose of this article is to discuss systematic reviews, how they are performed, and their associated strengths and limitations. A systematic review is an assessment of evidence involving exact methods to systematically identify, select, and critically evaluate all available literature on a particular topic. Unlike most narrative reviews, systematic reviews have defined methods established a priori for searching, evaluating, extracting, synthesizing, and reporting available evidence. Key characteristics differentiating systematic reviews from most narrative reviews include: clearly stated objectives, pre-defined inclusion/exclusion criteria, an explicit reproducible methodology, systematic exhaustive searches to identify all sources of evidence, an assessment of the validity for each included study, and a systematic presentation of the study characteristics/results. Though there are significant advantages to systematic reviews, there are also clear limitations such as: the quality of included evidence; heterogeneity and homogeneity of included studies; and publication bias. Even with these limitations, systematic reviews are beneficial to front line clinicians when the quantity of evidence is so substantial that reviewing and synthesizing it is not feasible, available evidence is conflicting, or when the robustness of available evidence is unknown.

    Several categories of drugs to treat osteoporosis exist in the form of bisphosphonates, strontium, parathyroid hormone, and selective estrogen receptor modulators (SERM).

    2000-01-01

    A systematic review is a carefully planned and conducted study designed to answer a specific focused clinical question. A systematic review differs from the frequently encountered narrative review article. Systematic review must be completed using a prespecified methodology. The reader must ask eight important questions when reading a systematic review: (i) did the review address a focused clinical question (ii) is it likely that important, relevant studies are missed (iii) were the inclusion criteria used to select appropriate articles (iv) was the validity of the included studies assessed (v) were the assessments of studies reproducible (vi) were the results similar from study to study (vii) what were the overall results and how precise are they and (viii) will the results help in caring for patients. The article also provides sources for systematic reviews.

    Retinal implants present an innovative way of restoring sight in degenerative retinal diseases. Previous reviews of research progress were written by groups developing their own devices. This systematic review objectively compares selected models by examining publications describing five representative retinal prostheses: Argus II, Boston Retinal Implant Project, Epi-Ret 3, Intelligent Medical Implants (IMI) and Alpha-IMS (Retina Implant AG). Publications were analysed using three criteria for interim success: clinical availability, vision restoration potential and long-term biocompatibility. Clinical availability: Argus II is the only device with FDA approval. Argus II and Alpha-IMS have both received the European CE Marking. All others are in clinical trials, except the Boston Retinal Implant, which is in animal studies. Vision restoration: resolution theoretically correlates with electrode number. Among devices with external cameras, the Boston Retinal Implant leads with 100 electrodes, followed by Argus II with 60 electrodes and visual acuity of 20/1262. Instead of an external camera, Alpha-IMS uses a photodiode system dependent on natural eye movements and can deliver visual acuity up to 20/546. Long-term compatibility: IMI offers iterative learning; Epi-Ret 3 is a fully intraocular device; Alpha-IMS uses intraocular photosensitive elements. Merging the results of these three criteria, Alpha-IMS is the most likely to achieve long-term success decades later, beyond current clinical availability.

    Individuals with mental health problems may face barriers to accessing effective psychotherapies. Videoconferencing technology, which allows audio and video information to be shared concurrently across geographical distances, offers an alternative that may improve access. We conducted a systematic literature review of the use of videoconferencing psychotherapy (VCP), designed to address 10 specific questions, including therapeutic types/formats that have been implemented, the populations with which VCP is being used, the number and types of publications related to VCP, and available satisfaction, feasibility, and outcome data related to VCP. After electronic searches and reviews of reference lists, 821 potential articles were identified, and 65 were selected for inclusion. The results indicate that VCP is feasible, has been used in a variety of therapeutic formats and with diverse populations, is generally associated with good user satisfaction, and is found to have similar clinical outcomes to traditional face-to-face psychotherapy. Although the number of articles being published on VCP has increased in recent years, there remains a need for additional large-scale clinical trials to further assess the efficacy and effectiveness of VCP.

    The purpose of this research was to review the literature on masked hypertension. Studies, reviews and editorials on masked hypertension were identified by PubMed, Pascal BioMed and Cochrane literature systematic searches. Then, we carried out a meta-analysis of the six cohort studies reporting quantitative data for masked hypertension prognosis. There is still no clear consensus definition of masked hypertension and the reproducibility of the phenomenon is unknown. Nevertheless, the prevalence of masked hypertension seems to lie between 8 and 20%, and can be up to 50% in treated hypertensive patients. Subjects with masked hypertension have a higher risk of cardiovascular accidents [hazard ratios: 1.92 (1.51-2.44)] than normotensive subjects. This is due to a possible failure to recognize and appropriately manage this particular form of hypertension, the frequent association with other risk factors and coexisting target organ damage. The remaining unresolved questions are as follows: is masked hypertension a clinical entity that requires identification and characterization or a statistical phenomenon linked to the variability of blood pressure measurements?; because screening of the entire population is not feasible, how to identify individuals with masked hypertension?; and, in the absence of randomized trial, how to treat masked hypertension?

Taking this into consideration, the present study was based on the following question: what practical contributions to clinicians and researchers does the current literature on childhood depression have to offer? The objective of the present study was to conduct a systematic review of articles regarding childhood depression. To accomplish this purpose, a systematic review of articles on childhood depression, published from January 1, 2010 to November 24, 2012, on MEDLINE and SciELO databases was carried out. Search terms were “depression” (medical subject headings [MeSH], “child” (MeSH, and "childhood depression" (keyword. Of the 180 retrieved studies, 25 met the eligibility criteria. Retrieved studies covered a wide range of aspects regarding childhood depression, such as diagnosis, treatment, prevention and prognosis. Recent scientific literature regarding childhood depression converge to, directly or indirectly, highlight the negative impacts of depressive disorders to the children's quality of life. Unfortunately, the retrieved studies show that childhood depression commonly grows in a background of vulnerability and poverty, where individual and familiar needs

    Systematic reviews of preclinical studies, in vivo animal experiments in particular, can influence clinical research and thus even clinical care. Dissemination bias, selective dissemination of positive or significant results, is one of the major threats to validity in systematic reviews also in the realm of animal studies. We conducted a systematic review to determine the number of published systematic reviews of animal studies until present, to investigate their methodological features especially with respect to assessment of dissemination bias, and to investigate the citation of preclinical systematic reviews on clinical research. Eligible studies for this systematic review constitute systematic reviews that summarize in vivo animal experiments whose results could be interpreted as applicable to clinical care. We systematically searched Ovid Medline, Embase, ToxNet, and ScienceDirect from 1st January 2009 to 9th January 2013 for eligible systematic reviews without language restrictions. Furthermore we included articles from two previous systematic reviews by Peters et al. and Korevaar et al. The literature search and screening process resulted in 512 included full text articles. We found an increasing number of published preclinical systematic reviews over time. The methodological quality of preclinical systematic reviews was low. The majority of preclinical systematic reviews did not assess methodological quality of the included studies (71%), nor did they assess heterogeneity (81%) or dissemination bias (87%). Statistics quantifying the importance of clinical research citing systematic reviews of animal studies showed that clinical studies referred to the preclinical research mainly to justify their study or a future study (76%). Preclinical systematic reviews may have an influence on clinical research but their methodological quality frequently remains low. Therefore, systematic reviews of animal research should be critically appraised before translating them

  5. Review of Hydraulic Fracturing for Preconditioning in Cave Mining

    2016-12-01

    Hydraulic fracturing has been used in cave mining for preconditioning the orebody following its successful application in the oil and gas industries. In this paper, the state of the art of hydraulic fracturing as a preconditioning method in cave mining is presented. Procedures are provided on how to implement prescribed hydraulic fracturing by which effective preconditioning can be realized in any in situ stress condition. Preconditioning is effective in cave mining when an additional fracture set is introduced into the rock mass. Previous studies on cave mining hydraulic fracturing focused on field applications, hydraulic fracture growth measurement and the interaction between hydraulic fractures and natural fractures. The review in this paper reveals that the orientation of the current cave mining hydraulic fractures is dictated by and is perpendicular to the minimum in situ stress orientation. In some geotechnical conditions, these orientation-uncontrollable hydraulic fractures have limited preconditioning efficiency because they do not necessarily result in reduced fragmentation sizes and a blocky orebody through the introduction of an additional fracture set. This implies that if the minimum in situ stress orientation is vertical and favors the creation of horizontal hydraulic fractures, in a rock mass that is already dominated by horizontal joints, no additional fracture set is added to that rock mass to increase its blockiness to enable it cave. Therefore, two approaches that have the potential to create orientation-controllable hydraulic fractures in cave mining with the potential to introduce additional fracture set as desired are proposed to fill this gap. These approaches take advantage of directional hydraulic fracturing and the stress shadow effect, which can re-orientate the hydraulic fracture propagation trajectory against its theoretical predicted direction. Proppants are suggested to be introduced into the cave mining industry to enhance the

    To systematically summarise the peer-reviewed literature relating to the aetiology, clinical presentation, investigation and treatment of geniculate neuralgia. Articles published in English between 1932 and 2012, identified using Medline, Embase and Cochrane databases. The search terms 'geniculate neuralgia', 'nervus intermedius neuralgia', 'facial pain', 'otalgia' and 'neuralgia' were used to identify relevant papers. Fewer than 150 reported cases were published in English between 1932 and 2012. The aetiology of the condition remains unknown, and clinical presentation varies. Non-neuralgic causes of otalgia should always be excluded by a thorough clinical examination, audiological assessment and radiological investigations before making a diagnosis of geniculate neuralgia. Conservative medical treatment is always the first-line therapy. Surgical treatment should be offered if medical treatment fails. The two commonest surgical options are transection of the nervus intermedius, and microvascular decompression of the nerve at the nerve root entry zone of the brainstem. However, extracranial intratemporal division of the cutaneous branches of the facial nerve may offer a safer and similarly effective treatment. The response to medical treatment for this condition varies between individuals. The long-term outcomes of surgery remain unknown because of limited data.

    Full Text Available Abstract Background Since its inception, evidence-based medicine and its application through systematic reviews, has been widely accepted. However, it has also been strongly criticised and resisted by some academic groups and clinicians. One of the main criticisms of evidence-based medicine is that it appears to claim to have unique access to absolute scientific truth and thus devalues and replaces other types of knowledge sources. Discussion The various types of clinical knowledge sources are categorised on the basis of Kant's categories of knowledge acquisition, as being either 'analytic' or 'synthetic'. It is shown that these categories do not act in opposition but rather, depend upon each other. The unity of analysis and synthesis in knowledge acquisition is demonstrated during the process of systematic reviewing of clinical trials. Systematic reviews constitute comprehensive synthesis of clinical knowledge but depend upon plausible, analytical hypothesis development for the trials reviewed. The dangers of systematic error regarding the internal validity of acquired knowledge are highlighted on the basis of empirical evidence. It has been shown that the systematic review process reduces systematic error, thus ensuring high internal validity. It is argued that this process does not exclude other types of knowledge sources. Instead, amongst these other types it functions as an integrated element during the acquisition of clinical knowledge. Conclusions The acquisition of clinical knowledge is based on interaction between analysis and synthesis. Systematic reviews provide the highest form of synthetic knowledge acquisition in terms of achieving internal validity of results. In that capacity it informs the analytic knowledge of the clinician but does not replace it.

    Research indicates that the methods used to identify data for systematic reviews of adverse effects may need to differ from other systematic reviews. To compare search methods in systematic reviews of adverse effects with other reviews. The search methodologies in 849 systematic reviews of adverse effects were compared with other reviews. Poor reporting of search strategies is apparent in both systematic reviews of adverse effects and other types of systematic reviews. Systematic reviews of adverse effects are less likely to restrict their searches to MEDLINE or include only randomised controlled trials (RCTs). The use of other databases is largely dependent on the topic area and the year the review was conducted, with more databases searched in more recent reviews. Adverse effects search terms are used by 72% of reviews and despite recommendations only two reviews report using floating subheadings. The poor reporting of search strategies in systematic reviews is universal, as is the dominance of searching MEDLINE. However, reviews of adverse effects are more likely to include a range of study designs (not just RCTs) and search beyond MEDLINE. © 2014 Crown Copyright.

    As faculty members, we frequently find that first-year doctoral students in nursing are confused about how to conduct a systematic integrated literature review. This could be due to its vague definition and a lack of recent literature that provides directions for conducting a systematic integrated literature review. This article aims to provide directions for conducting a systematic integrated literature review by identifying the essential components of published literature reviews in nursing. To achieve this goal, the literature was searched by using the keywords nursing, systematic, and review in multiple databases. A total of 267 articles were selected and are included in this systematic integrated literature review. The articles were then sorted by study design and analyzed in six areas of interests. Finally, a practical guideline for conducting systematic integrated literature reviews is proposed based on the analysis of the literature.

    Full Text Available Background: Various methods have been used to stabilize the vertebra in cervical fractures, including the use of various orthoses and surgery. However, it is not cleared which type of orthosis is more suitable for the subjects with cervical fractures to best immobilize the vertebra and to decrease the associated side effects. Therefore, the aim of this study was to evaluate the efficiency of various orthoses based on the available literature. Materials and Methods: A search was done in some databases include PubMed, ISI Web of Knowledge, EBSCO, Embasco, and Google Scholar. The search was done with some key words such as: Cervical spine injuries; odontoid fractures; hangman′s fractures; axis fracture; axis, atlas, cervical fractures; trauma; neck fracture; neck injury in combination with cervical orthoses. The quality of the studies was evaluated by use of Downs and Black assessment and Assessment of Multiple Systematic Reviews (AMSTAR for original research and review articles, respectively. Results: Based on the aforementioned key words, 25 papers were selected. The quality of the studies varies 10-24. Most of the studies were on the use of the halo vest orthosis, its side effects and also on complications associated with various orthoses. Discussion: Halo orthoses provide a high degree of restriction and immobilization; however, there are some side effects associated with this orthosis, including swallowing, pin loosening, and infection. It should be emphasized that other types of orthoses fewer complications, with reasonable outputs on motion restrictions.

    2015-03-01

    Full Text Available Hydraulic fracturing is widely accepted and applied to improve the gas recovery in unconventional reservoirs. Unconventional reservoirs to be addressed here are with very low permeability, complicated geological settings and in-situ stress field etc. All of these make the hydraulic fracturing process a challenging task. In order to effectively and economically recover gas from such reservoirs, the initiation and propagation of hydraulic fracturing in the heterogeneous fractured/porous media under such complicated conditions should be mastered. In this paper, some issues related to hydraulic fracturing have been reviewed, including the experimental study, field study and numerical simulation. Finally the existing problems that need to be solved on the subject of hydraulic fracturing have been proposed.

    The wide variety of readily available electronic media grants anyone the freedom to retrieve published references from almost any area of research around the world. Despite this privilege, keeping up with primary research evidence is almost impossible because of the increase in professional publishing across disciplines. Systematic reviews are a solution to this problem as they aim to synthesize all current information on a particular topic and present a balanced and unbiased summary of the findings. They are fast becoming an important method of research across a number of fields, yet only a small number of guidelines exist on how to define and select terms for a systematic search. This article presents a replicable method for selecting terms in a systematic search using the semantic concept recognition software called leximancer (Leximancer, University of Queensland, Brisbane, Australia). We use this software to construct a set of terms from a corpus of literature pertaining to transborder interventions for drug control and discuss the applicability of this method to systematic reviews in general. This method aims to contribute a more 'systematic' approach for selecting terms in a manner that is entirely replicable for any user.

  3. Systematic review of reviews of risk factors for intracranial aneurysms

    Clarke, Mike [National Institute for Health Research, UK Cochrane Centre, Oxford (United Kingdom)

    2008-08-15

    Systematic reviews of systematic reviews identify good quality reviews of earlier studies of medical conditions. This article describes a systematic review of systematic reviews performed to investigate factors that might influence the risk of rupture of an intracranial aneurysm. It exemplifies the technique of this type of research and reports the finding of a specific study. The annual incidence of subarachnoid haemorrhage resulting from the rupture of intracranial aneurysms is estimated to be nine per 100,000. A large proportion of people who have this bleed, will die or remain dependent on the care of others for some time. Reliable knowledge about the risks of subarachnoid haemorrhage in different populations will help in planning, screening and prevention strategies and in predicting the prognosis of individual patients. If the necessary data were available in the identified reviews, an estimate for the numerical relationship between a particular characteristic and the risk of subarachnoid haemorrhage was included in this report. The identification of eligible systematic reviews relied mainly on the two major bibliographic databases of the biomedical literature: PubMed and EMBASE. These were searched in 2006, using specially designed search strategies. Approximately 2,000 records were retrieved and each of these was checked carefully against the eligibility criteria for this systematic review. These criteria required that the report be a systematic review of studies assessing the risk of subarachnoid haemorrhage in patients known to have an unruptured intracranial aneurysm or of studies that had investigated the characteristics of people who experienced a subarachnoid haemorrhage without previously being known to have an unruptured aneurysm. Reports which included more than one systematic review were eligible and each of these reviews was potentially eligible. The quality of each systematic review was assessed. In this review, 16 separate reports were

    Full Text Available Abstract Background Policy makers and others often require synthesis of knowledge in an area within six months or less. Traditional systematic reviews typically take at least 12 months to conduct. Rapid reviews streamline traditional systematic review methods in order to synthesize evidence within a shortened timeframe. There is great variation in the process of conducting rapid reviews. This review sought to examine methods used for rapid reviews, as well as implications of methodological streamlining in terms of rigour, bias, and results. Methods A comprehensive search strategy--including five electronic databases, grey literature, hand searching of relevant journals, and contacting key informants--was undertaken. All titles and abstracts (n = 1,989 were reviewed independently by two reviewers. Relevance criteria included articles published between 1995 and 2009 about conducting rapid reviews or addressing comparisons of rapid reviews versus traditional reviews. Full articles were retrieved for any titles deemed relevant by either reviewer (n = 70. Data were extracted from all relevant methodological articles (n = 45 and from exemplars of rapid review methods (n = 25. Results Rapid reviews varied from three weeks to six months; various methods for speeding up the process were employed. Some limited searching by years, databases, language, and sources beyond electronic searches. Several employed one reviewer for title and abstract reviewing, full text review, methodological quality assessment, and/or data extraction phases. Within rapid review studies, accelerating the data extraction process may lead to missing some relevant information. Biases may be introduced due to shortened timeframes for literature searching, article retrieval, and appraisal. Conclusions This review examined the continuum between diverse rapid review methods and traditional systematic reviews. It also examines potential implications of streamlined review methods. More of

    2003-01-01

    A hip fracture epidemic is occurring in developed countries in association with population aging. The increasing number of people with a hip fracture has major implications for clinicians and health service managers. More importantly, a hip fracture is a devastating event in the life of an older person, as it often leads to loss of independence and death. Identification of risk factors for hip fracture is an essential first step towards prevention. The use of psychotropic medications is an established risk factor for hip fracture. The purpose of this article is to systematically review epidemiological studies of the relationship between use of benzodiazepines and risk of hip fracture and, then, to see how the findings of these studies fit with what is known about the pharmacology of benzodiazepines. Eleven primary epidemiological studies were identified. The results of these studies were not consistent; however, the inconsistency appeared to be almost entirely explained by research design. The studies that did not show an association between increased hip fracture risk and benzodiazepine use were nearly all hospital-based case-control studies, a type of study that often lacks validity because of the difficulty of finding an appropriate control group. After excluding the hospital-based case-control studies, all but one of the remaining seven studies found that use of benzodiazepines was associated with an increased risk of hip fracture that varied between 50% and 110%. The only higher quality study that did not find an association between benzodiazepine use and hip fracture was also the only study conducted entirely in nursing homes. There was no evidence that the risk of hip fracture differed between short- and long-acting benzodiazepines. People using higher doses of benzodiazepines and those who had recently started using benzodiazepines were at the highest risk of hip fracture. In very old people, there was some preliminary evidence that benzodiazepines that

    Abstract Background Hundreds of studies of maternity care interventions have been published, too many for most people involved in providing maternity care to identify and consider when making decisions. It became apparent that systematic reviews of individual studies were required to appraise, summarise and bring together existing studies in a single place. However, decision makers are increasingly faced by a plethora of such reviews and these are likely to be of variable quality and scope, with more than one review of important topics. Systematic reviews (or overviews) of reviews are a logical and appropriate next step, allowing the findings of separate reviews to be compared and contrasted, providing clinical decision makers with the evidence they need. Methods The methods used to identify and appraise published and unpublished reviews systematically, drawing on our experiences and good practice in the conduct and reporting of systematic reviews are described. The process of identifying and appraising all published reviews allows researchers to describe the quality of this evidence base, summarise and compare the review\\'s conclusions and discuss the strength of these conclusions. Results Methodological challenges and possible solutions are described within the context of (i) sources, (ii) study selection, (iii) quality assessment (i.e. the extent of searching undertaken for the reviews, description of study selection and inclusion criteria, comparability of included studies, assessment of publication bias and assessment of heterogeneity), (iv) presentation of results, and (v) implications for practice and research. Conclusion Conducting a systematic review of reviews highlights the usefulness of bringing together a summary of reviews in one place, where there is more than one review on an important topic. The methods described here should help clinicians to review and appraise published reviews systematically, and aid evidence-based clinical decision-making.

    Objective. The present paper examines pertinent literature sources published in the peer-reviewed English language between 1980 and November 1, 2010 concerning hip fractures. The aim was to highlight potential intervention points to offset the risk of incurring a hip fracture and its attendant disability. Methods. An in-depth search of the literature using the key terms: disability, epidemiology, hip fracture, prevention, and risk factors was conducted, along with data from the author's research base detailing the disability associated with selected hip fracture cases. All articles that dealt with these key topics were reviewed, and relevant data were tabulated and analyzed. Results. Hip fractures remain an important but potentially preventable public health problem. Among the many related remediable risk factors, low physical activity levels are especially important. Related determinants of suboptimal neuromuscular function also contribute significantly to hip fracture disability. Conclusion. Physical activity participation can help to reduce the prevalence and excess disability of hip fractures and should be encouraged. PMID:21584248

    Galeazzi fracture associated with ipsilateral posterior elbow dislocation and radial head fracture is a rare pattern of injury. Few reports exist that describes this injury pattern and its treatment. We describe a case report of simultaneous occurrence of Galeazzi fracture and ipsilateral dislocation of elbow. A 58 year-old female presented with Galeazzi fracture and posterior elbow dislocation associated with radial head fracture of left upper extremity. This was managed with closed reduction of the elbow, open reduction and internal fixation of the radial shaft fracture and K-wire stabilisation of the unstable distal radioulnar joint. Prophylactic fasciotomy was performed. At 10 months follow-up, the outcome was favourable with the American shoulder and elbow surgeon score of 92 and the disabilities of the arm, shoulder and hand score of 18. The presumed mechanism of the injury was a forceful axial loading of a hyperpronated forearm and extended elbow. Our literature review shows that this pattern of injury occurs as a result of high energy trauma in young individuals, and successful outcome can be achieved by addressing each component of this complex injury individually. Simultaneous occurrence of elbow dislocation and Galeazzi fracture seems to be the result of extreme axial force and unique position of upper extremity at the time of impact. Individualised approach to each component of this injury can result in favourable outcome. Crown Copyright © 2013. Published by Elsevier Ltd. All rights reserved.

    Full Text Available Abstract Background Vitamin D supplementation for fracture prevention is widespread despite conflicting interpretation of relevant randomised controlled trial (RCT evidence. This study summarises quantitatively the current evidence from RCTs and observational studies regarding vitamin D, parathyroid hormone (PTH and hip fracture risk. Methods We undertook separate meta-analyses of RCTs examining vitamin D supplementation and hip fracture, and observational studies of serum vitamin D status (25-hydroxyvitamin D (25(OHD level, PTH and hip fracture. Results from RCTs were combined using the reported hazard ratios/relative risks (RR. Results from case-control studies were combined using the ratio of 25(OHD and PTH measurements of hip fracture cases compared with controls. Original published studies of vitamin D, PTH and hip fracture were identified through PubMed and Web of Science databases, searches of reference lists and forward citations of key papers. Results The seven eligible RCTs identified showed no significant difference in hip fracture risk in those randomised to cholecalciferol or ergocalciferol supplementation versus placebo/control (RR = 1.13[95%CI 0.98-1.29]; 801 cases, with no significant difference between trials of 21 (heterogeneity = 51.02, p 216 (heterogeneity = 137.9, p 29 (heterogeneity = 149.68, p Conclusions Neither higher nor lower dose vitamin D supplementation prevented hip fracture. Randomised and observational data on vitamin D and hip fracture appear to differ. The reason for this is unclear; one possible explanation is uncontrolled confounding in observational studies. Post-fracture PTH levels are unrelated to hip fracture risk.

    Kawasaki disease is a complex and potentially serious condition. It has been observed in temporal relation to immunisation. We conducted a systematic literature review using various reference sources to review the available evidence published in the literature. We identified twenty seven publications reporting a temporal association between immunisation and Kawasaki disease. We present a systematic review of data drawn from randomised controlled trials, observational studies, case series and reports, and reviews. Overall there was a lack of standardised case definitions, making data interpretation and comparability challenging. Although a temporal relationship between immunisation and Kawasaki disease is suggested, evidence for an increased risk or a causal association is lacking. Implementation of a standardised Kawasaki disease case definition would increase confidence in the findings and add value to future studies of pre- or post-licensure vaccine safety studies.

    2015-05-01

    Denture adhesives have been the objective of scientific research for over half a century. Although they are used by denture wearers worldwide, investigations of their effectiveness and biocompatibility have led to controversial conclusions. The purpose of this study was to review the literature data with regard to the effectiveness and biocompatibility of denture adhesives as well as the attitudes of both patients and dental professionals toward these materials. An electronic search of English peer-reviewed dental literature in the Medline database was conducted to evaluate the effectiveness and biocompatibility of denture adhesives. There was no limitation in publication year, so the search included all the available scientific evidence included in that particular database until March 2014. Specific inclusion criteria were used for the selection of the appropriate articles. A manual search of the citations of the obtained articles followed to extend the electronic search. A full text review was carried out for only 32 articles. Of the 32 articles, 21 examined the efficacy of denture adhesives in terms of retention and stability and masticatory performance, 6 evaluated the issue of the biocompatibility of denture adhesives, and 5 presented the attitudes of either professionals or patients toward these materials. The majority of clinical studies supported the fact that denture adhesives enhance the retention, stability, and masticatory performance of a removable prosthesis. In terms of biocompatibility, long-term in vivo studies to investigate potential harmful effects were lacking. Patients are satisfied with denture adhesives that meet their needs.

    The purpose of this study is to review the available literature related to composite inlays. Electronic databases published up to November 2013 were searched. Studies that evaluate composite resin inlays for the restoration of posterior teeth were selected. The studies should compare composite inlays against gold inlays, ceramic inlays and direct composite fillings regarding longevity, aesthetic quality and postoperative sensitivity or comparing the clinical effectiveness of them on premolars versus molars or on 1-2 surface preparations versus multi-surface preparations. Despite the heterogeneity of the available clinical trials composite inlays seem to be an effective method for the restoration of posterior teeth.

    Full Text Available Objective: this study aimed to review the literature regarding late preterm births (34 weeks to 36 weeks and 6 days of gestation in its several aspects. Sources: the MEDLINE, LILACS, and Cochrane Library databases were searched, and the references of the articles retrieved were also used, with no limit of time. Data synthesis: numerous studies showed a recent increase in late preterm births. In all series, late preterm comprised the majority of preterm births. Studies including millions of births showed a strong association between late preterm birth and neonatal mortality. A higher mortality in childhood and among young adults was also observed. Many studies found an association with several neonatal complications, and also with long-term disorders and sequelae: breastfeeding problems, cerebral palsy, asthma in childhood, poor school performance, schizophrenia, and young adult diabetes. Some authors propose strategies to reduce late preterm birth, or to improve neonatal outcome: use of antenatal corticosteroids, changes in some of the guidelines for early delivery in high-risk pregnancies, and changes in neonatal care for this group. Conclusions: numerous studies show greater mortality and morbidity in late preterm infants compared with term infants, in addition to long-term disorders. More recent studies evaluated strategies to improve the outcomes of these neonates. Further studies on these strategies are needed.

    2017-07-01

    Cognitive insight is the ability to re-evaluate thoughts and beliefs in order to make thoughtful conclusions. It differs from clinical insight, as it focuses on more general metacognitive processes. Therefore, it could be relevant to diverse disorders and non-clinical subjects. There is a growing body of research on cognitive insight in individuals with and without psychosis. This review has summarised the current state of the art regarding this topic. We conclude that while cognitive insight in its current form seems valid for use in individuals with psychosis, it is less so for individuals without psychosis. Additionally, higher cognitive insight not always leads to better psychological functioning. For instance, higher levels of self-reflection are often associated with depressive mood. We therefore recommend the sub-components of cognitive insight to be studied separately. Also, it is unclear what position cognitive insight takes within the spectrum of metacognitive processes and how it relates to other self-related concepts that have been defined previously in literature. Combining future and past research on cognitive insight and its analogue concepts will help in the formation of a uniform definition that fits all subjects discussed here. Copyright © 2017.

    Acupuncture is a medical procedure with a very wide range of indications according to the WHO. However the indications require robust scientific evidence to support them. We have conducted a systematic review (2010-2015) in order to define in which pathologies acupuncture can be an effective strategy, STRICTA criteria that aim to set up acupuncture clinical trials standard criteria were defined in 2010. Only systematic reviews and meta-analyses of good or very good methodological quality according to SIGN criteria were selected. Its main objective was to evaluate the effectiveness of acupuncture in the management of any disease. Most of the final 31 selected reviews focus on chronic pain-related diseases, mainly in the disciplines of Neurology, Orthopaedics and Rheumatology. Current evidence supports the use of acupuncture in the treatment of headaches, migraines, back pain, cervical pain and osteoarthritis. The remaining pathologies still require further good quality studies.

    More and more systematic reviews of diagnostic test accuracy studies are being published, but they can be methodologically challenging. In this paper, the authors present some of the recent developments in the methodology for conducting systematic reviews of diagnostic test accuracy studies. Restrictive electronic search filters are discouraged, as is the use of summary quality scores. Methods for meta-analysis should take into account the paired nature of the estimates and their dependence on threshold. Authors of these reviews are advised to use the hierarchical summary receiver-operating characteristic or the bivariate model for the data analysis. Challenges that remain are the poor reporting of original diagnostic test accuracy studies and difficulties with the interpretation of the results of diagnostic test accuracy research.

    Full Text Available Abstract Background Maternity care providers, particularly midwives, have a window of opportunity to influence pregnant women about positive health choices. This aim of this paper is to identify evidence of effective public health interventions from good quality systematic reviews that could be conducted by midwives. Methods Relevant databases including MEDLINE, Pubmed, EBSCO, CRD, MIDIRS, Web of Science, The Cochrane Library and Econlit were searched to identify systematic reviews in October 2010. Quality assessment of all reviews was conducted. Results Thirty-six good quality systematic reviews were identified which reported on effective interventions. The reviews were conducted on a diverse range of interventions across the reproductive continuum and were categorised under: screening; supplementation; support; education; mental health; birthing environment; clinical care in labour and breast feeding. The scope and strength of the review findings are discussed in relation to current practice. A logic model was developed to provide an overarching framework of midwifery public health roles to inform research policy and practice. Conclusions This review provides a broad scope of high quality systematic review evidence and definitively highlights the challenge of knowledge transfer from research into practice. The review also identified gaps in knowledge around the impact of core midwifery practice on public health outcomes and the value of this contribution. This review provides evidence for researchers and funders as to the gaps in current knowledge and should be used to inform the strategic direction of the role of midwifery in public health in policy and practice.

    Cholecystectomy rates for biliary dyskinesia in children are rising in the United States, but not in other countries. Biliary dyskinesia is a validated functional gallbladder disorder in adults, requiring biliary colic in the diagnosis. In contrast, most studies in children require upper abdominal pain, absent gallstones on ultrasound, and an abnormal gallbladder ejection fraction (GBEF) on cholecystokinin-stimulated cholescintigraphy for diagnosis. We aimed to systematically review existing literature in biliary dyskinesia in children, determine the validity and reliability of diagnostic criteria, GBEF, and to assess outcomes following cholecystectomy. We performed a systematic review following the PRISMA checklist and searched 7 databases including PubMed, Scopus, Embase, Ovid, MEDLINE, ProQuest, Web of Science, and the Cochrane library. Bibliographies of articles were screened for additional studies. Our search terms yielded 916 articles of which 28 were included. Three articles were manually added from searched references. We reviewed 31 peer-reviewed publications, all retrospective chart reviews. There was heterogeneity in diagnostic criteria and GBEF values. Outcomes after laparoscopic cholecystectomy varied from 34% to 100% success, and there was no consensus concerning factors influencing outcomes. The observational, retrospective study designs that comprised our review limited interpretation of safety and efficacy of the investigations and treatment in biliary dyskinesia in children. Symptoms of biliary dyskinesia overlapped with functional dyspepsia. There is a need for consensus on symptoms defining biliary dyskinesia, validation of testing required for diagnosis of biliary dyskinesia, and randomized controlled trials comparing medical versus surgical management in children with upper abdominal pain.

  12. Educational attainment and obesity: a systematic review.

    Cohen, A K; Rai, M; Rehkopf, D H; Abrams, B

    2013-12-01

    Although previous systematic reviews considered the relationship between socioeconomic status and obesity, almost 200 peer-reviewed articles have been published since the last review on that topic, and this paper focuses specifically on education, which has different implications. The authors systematically review the peer-reviewed literature from around the world considering the association between educational attainment and obesity. Databases from public health and medicine, education, psychology, economics, and other social sciences were searched, and articles published in English, French, Portuguese and Spanish were included. This paper includes 289 articles that report on 410 populations in 91 countries. The relationship between educational attainment and obesity was modified by both gender and the country's economic development level: an inverse association was more common in studies of higher-income countries and a positive association was more common in lower-income countries, with stronger social patterning among women. Relatively few studies reported on lower-income countries, controlled for a comprehensive set of potential confounding variables and/or attempted to assess causality through the use of quasi-experimental designs. Future research should address these gaps to understand if the relationship between educational attainment and obesity may be causal, thus supporting education policy as a tool for obesity prevention. © 2013 The Authors. obesity reviews © 2013 International Association for the Study of Obesity.

    2010-04-01

    The aim of this study is to perform a narrative review of systematic reviews of diagnostic tests accuracy. We undertook a search using The Cochrane Methodology Reviews (Cochrane Reviews of Diagnostic Test Accuracy), Medline and LILACS up to October 2009. Reference lists of included studies were also hand searched. The following search strategy was constructed by using a combination of subject headings and text words: 1. Cochrane Methodology Reviews: accuracy study "Methodology" 2. In Pubmed "Meta-Analysis" [Publication Type] AND "Evidence-Based Medicine" [Mesh]) AND "Sensitivity and Specificity" [Mesh] 3. LILACS (revisao sistematica) or "literatura de REVISAO como assunto" [Descritor de assunto] and (sistematica) or "SISTEMATICA" [Descritor de assunto] and (acuracia) or "SENSIBILIDADE e especificidade" [Descritor de assunto]. In summary, the methodological planning and preparation of systematic reviews of therapeutic interventions are prior to that used in systematic reviews of diagnostic tests accuracy. There are more sources of heterogeneity in design of diagnostic test studies, which impair the synthesis - meta-analysis - of the results. To work around this problem, there are currently uniform requirements for diagnostic test manuscripts submitted to leading biomedical journals.

  1. Review of traumatic diaphragmatic hernia associated with pelvis fractures

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    Objective: To review the epidemiological feature, clinical and diagnostic data of post-traumatic diaphragmatic hernia (TDH) associated with pelvis fracture reported in recent 10 years.Methods: A 10-year retrospective study was undertaken to analyze the incidence, diagnosis, management, morbidity and mortality of patients with traumatic diaphragmatic hernia associated with pelvis fractures. A total of 46 cases in our country were reviewed.Results: The incidence of TDH associated with pelvis fractures was relatively rare and the diagnosis was often delayed or missed. A total of 72.34% of these patients were diagnosed as TDH associated with pelvis fractures after injury for 36 hours to 1 week. Although the trans-thorax approach was preferred for surgical closure in the acute phase, its mortality still reached 8.51%.Conclusions: TDH associated with pelvis fractures is difficult to be diagnosed because of its varied clinical and radiological signs and the patients may not present with symptoms for a long time after injury. In clinical, a high index of suspicion with appropriate examination is the mainstay of management, which can be helpful in prognosis.

    The current systematic review study is aimed at critically analyzing from a clinimetric viewpoint the clinical consequence of somatization in Parkinson's Disease (PD). By focusing on the International Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we conducted a comprehensive electronic literature research strategy on ISI Web-of-Science, PsychINFO, PubMed, EBSCO, ScienceDirect, MEDLINE, Scopus, and Google Scholar databases. Out of 2.926 initial records, only a total of 9 studies were identified as clearly relevant and analyzed in this systematic review. The prevalence of somatization in PD has been found to range between 7.0% and 66.7%, with somatoform disorders acting as clinical factor significantly contributing to predict a progressive cognitive impairment. We highlighted that somatization is a highly prevalent comorbidity affecting PD. However, the clinical consequence of such psychiatric symptom should be further evaluated by replacing the clinically inadequate diagnostic label of psychogenic parkinsonism with the psychosomatic concept of persistent somatization as conceived by the Diagnostic Criteria for Psychosomatic Research (DCPR).

    2013-04-01

    Doppler echocardiography (Echo) is a non-invasive method of excellent accuracy to screen portopulmonary hypertension (PPH) and to assess intrapulmonary shunts (IPS) in chronic liver disease (CLD). In the past decade, Echo proved to play a fundamental role in the diagnosis of cirrhotic cardiomyopathy (CCM). To perform a systematic review of relevant articles on the subject 'Echo in CLD'. In November 2011, a systematic review was performed in the PubMed, LILACS and SciELO databases, and the characteristics of the studies selected were reported. The search based on descriptors and free terms obtained 204 articles (179 in Pubmed, 21 in LILACS, and 1 in SciELO). Of those 204 articles, 22 were selected for systematic review. A meta-analysis could not be performed because of the heterogeneity of the articles. Echo should be part of CLD stratification for screening PPH, IPS and CCM, because, most of the time, such complications are diagnosed only when patients are already waiting for a liver transplant.

    本综述的目的是阐明艾滋病合并骨科手术患者围手术期防护措施,以减少暴露风险。在手术前,患者必须启动高效抗反转录病毒治疗以减少医务人员职业暴露的风险;在医疗活动中,医务人员要戴面罩和口罩;在术中,基于骨科手术常见的暴露风险,要求医务人员戴双层手套、眼罩,穿防护服,术中尽可能减少锐利器械和刀具的使用、尽可能进行无接触手术,以减少术中职业暴露的风险。如术中发生职业暴露,应尽早进行职业暴露后预防。基于艾滋病患者骨科手术职业暴露的风险的研究,建立了具有中国特色的围术期防护措施,这有助于减少骨科手术患者职业暴露的风险。%The objective for this review was to elucidate the perioperative protective measure in HIV/AIDS patients with fracture in China. In pre-operative period, high active antiretroviral therapy ( HAART) must be initiated as an important measure to reduce the incidence of occupational exposure, and healthcare workers should wear face masks and gloves when performing medical practice. In operative period, based on the characteristics of occupational exposure in operations, we took some measures to reduce the risk of occupational exposure, including bilayer gloves, eye mask, disposable waterproof gown, and slippers with foot-strap, advised to minimize the use of sharp or electrical instruments and argon knifes, and advised contactless operation as far as possible to reduce opportunity of occupational exposure. Once occupational exposure occurred in surgical operation, post exposure prophylaxis must be taken immediately. We established perioperative protective measures with Chinese characteristics based on research on orthopedic surgery process in human immunodeficiency virus/acquired immune deficiency syndrome ( HIV/AIDS ) patients, which helped reduce the risk of occupational exposure in orthopedic surgery.

  5. Systematic reviews in bioethics: types, challenges, and value.

    Science.gov (United States)

    McDougall, Rosalind

    2014-02-01

    There has recently been interest in applying the techniques of systematic review to bioethics literature. In this paper, I identify the three models of systematic review proposed to date in bioethics: systematic reviews of empirical bioethics research, systematic reviews of normative bioethics literature, and systematic reviews of reasons. I argue that all three types yield information useful to scholarship in bioethics, yet they also face significant challenges particularly in relation to terminology and time. Drawing on my recent experience conducting a systematic review, I suggest that complete comprehensiveness may not always be an appropriate goal of a literature review in bioethics, depending on the research question. In some cases, all the relevant ideas may be captured without capturing all the relevant literature. I conclude that systematic reviews in bioethics have an important role to play alongside the traditional broadbrush approach to reviewing literature in bioethics.

    Objective To provide an overview of effective interventions aimed at reducing rates of adverse events in hospitals. Design Systematic review of systematic reviews. Data sources PubMed, CINAHL, PsycINFO, the Cochrane Library and EMBASE were searched for systematic reviews published until October 2015. Study selection English-language systematic reviews of interventions aimed at reducing adverse events in hospitals, including studies with an experimental design and reporting adverse event rates, were included. Two reviewers independently assessed each study's quality and extracted data on the study population, study design, intervention characteristics and adverse patient outcomes. Results Sixty systematic reviews with moderate to high quality were included. Statistically significant pooled effect sizes were found for 14 types of interventions, including: (1) multicomponent interventions to prevent delirium; (2) rapid response teams to reduce cardiopulmonary arrest and mortality rates; (3) pharmacist interventions to reduce adverse drug events; (4) exercises and multicomponent interventions to prevent falls; and (5) care bundle interventions, checklists and reminders to reduce infections. Most (82%) of the significant effect sizes were based on 5 or fewer primary studies with an experimental study design. Conclusions The evidence for patient-safety interventions implemented in hospitals worldwide is weak. The findings address the need to invest in high-quality research standards in order to identify interventions that have a real impact on patient safety. Interventions to prevent delirium, cardiopulmonary arrest and mortality, adverse drug events, infections and falls are most effective and should therefore be prioritised by clinicians. PMID:27687901

    2017-01-01

    Full Text Available Introduction. A burgeoning number of systematic reviews considering lurasidone in the treatment of bipolar depression have occurred since its Food and Drug Administration extended approval in 2013. While a paucity of available quantitative evidence still precludes preliminary meta-analysis on the matter, the present quality assessment of systematic review of systematic reviews, nonetheless, aims at highlighting current essential information on the topic. Methods. Both published and unpublished systematic reviews about lurasidone mono- or adjunctive therapy in the treatment of bipolar depression were searched by two independent authors inquiring PubMed/Cochrane/Embase/Scopus from inception until October 2016. Results. Twelve included systematic reviews were of moderate-to-high quality and consistent in covering the handful of RCTs available to date, suggesting the promising efficacy, safety, and tolerability profile of lurasidone. Concordance on the drug profile seems to be corroborated by a steadily increasing number of convergent qualitative reports on the matter. Limitations. Publication, sponsorship, language, citation, and measurement biases. Conclusions. Despite being preliminary in nature, this overview stipulates the effectiveness of lurasidone in the acute treatment of Type I bipolar depression overall. As outlined by most of the reviewed evidence, recommendations for future research should include further controlled trials of extended duration.

  11. Vitamin D in Foot and Ankle Fracture Healing: A Literature Review and Research Design.

    Science.gov (United States)

    Bernhard, Andrew; Matuk, Jorge

    2015-10-01

    Vitamin D is a generic name for a group of essential vitamins, or secosteroids, important in calcium homeostasis and bone metabolism. Specifically, efficacy of vitamin D with regard to bone healing is in question. A literature review was performed, finding mostly large studies involving vitamin D effects on prevention of fractures and randomized animal model studies consisting of controlled fractures with vitamin D interventions. The prevention articles generally focus on at-risk populations, including menopausal women and osteoporotic patients, and also most often include calcium in the treatment group. Few studies look at vitamin D specifically. The animal model studies often focus more on vitamin D supplementation; however the results are still largely inconclusive. While recent case reports appear promising, the ambiguity of results on the topic of fracture healing suggests a need for more, higher level research. A novel study design is proposed to help determine the efficacy on vitamin D in fracture healing. Therapeutic, Level IV: Systematic Review. © 2015 The Author(s).

    Hundreds of studies of maternity care interventions have been published, too many for most people involved in providing maternity care to identify and consider when making decisions. It became apparent that systematic reviews of individual studies were required to appraise, summarise and bring together existing studies in a single place. However, decision makers are increasingly faced by a plethora of such reviews and these are likely to be of variable quality and scope, with more than one review of important topics. Systematic reviews (or overviews) of reviews are a logical and appropriate next step, allowing the findings of separate reviews to be compared and contrasted, providing clinical decision makers with the evidence they need.

    2016-01-01

    Research on the health of lesbian, gay, bisexual, and transgender (LGBT) populations can provide important information to address existing health inequalities. Finding existing research in LGBT health can prove challenging due to the plethora of terminology used. We sought to describe existing search strategies and to identify more comprehensive LGBT search terminology. We iteratively created a search string to identify systematic reviews and meta-analyses about LGBT health and implemented it in Embase, PubMed/MEDLINE, and PsycINFO databases on May 28-29, 2015. We hand-searched the journal LGBT Health. Inclusion criteria were: systematic reviews and meta-analyses that addressed LGBT health, used systematic searching, and used independent coders for inclusion. The published search terminology in each record and search strings provided by authors on request were cross-referenced with our original search to identify additional terminology. Our search process identified 19 systematic reviews meeting inclusion criteria. The number of search terms used to identify LGBT-related records ranged from 1 to 31. From the included studies, we identified 46 new search terms related to LGBT health. We removed five search terms as inappropriate and added five search terms used in the field. The resulting search string included 82 terms. There is room to improve the quality of searching and reporting in LGBT health systematic reviews. Future work should attempt to enhance the positive predictive value of LGBT health searches. Our findings can assist LGBT health reviewers in capturing the diversity of LGBT terminology when searching.

    2007-03-01

    Full Text Available BACKGROUND: Systematic reviews (SRs have become increasingly popular to a wide range of stakeholders. We set out to capture a representative cross-sectional sample of published SRs and examine them in terms of a broad range of epidemiological, descriptive, and reporting characteristics, including emerging aspects not previously examined. METHODS AND FINDINGS: We searched Medline for SRs indexed during November 2004 and written in English. Citations were screened and those meeting our inclusion criteria were retained. Data were collected using a 51-item data collection form designed to assess the epidemiological and reporting details and the bias-related aspects of the reviews. The data were analyzed descriptively. In total 300 SRs were identified, suggesting a current annual publication rate of about 2,500, involving more than 33,700 separate studies including one-third of a million participants. The majority (272 [90.7%] of SRs were reported in specialty journals. Most reviews (213 [71.0%] were categorized as therapeutic, and included a median of 16 studies involving 1,112 participants. Funding sources were not reported in more than one-third (122 [40.7%] of the reviews. Reviews typically searched a median of three electronic databases and two other sources, although only about two-thirds (208 [69.3%] of them reported the years searched. Most (197/295 [66.8%] reviews reported information about quality assessment, while few (68/294 [23.1%] reported assessing for publication bias. A little over half (161/300 [53.7%] of the SRs reported combining their results statistically, of which most (147/161 [91.3%] assessed for consistency across studies. Few (53 [17.7%] SRs reported being updates of previously completed reviews. No review had a registration number. Only half (150 [50.0%] of the reviews used the term "systematic review" or "meta-analysis" in the title or abstract. There were large differences between Cochrane reviews and non

  15. A systematic review of animal models for Staphylococcus aureus osteomyelitis

    2014-03-01

    Full Text Available Staphylococcus aureus (S. aureus osteomyelitis is a significant complication for orthopaedic patients undergoing surgery, particularly with fracture fixation and arthroplasty. Given the difficulty in studying S. aureus infections in human subjects, animal models serve an integral role in exploring the pathogenesis of osteomyelitis, and aid in determining the efficacy of prophylactic and therapeutic treatments. Animal models should mimic the clinical scenarios seen in patients as closely as possible to permit the experimental results to be translated to the corresponding clinical care. To help understand existing animal models of S. aureus, we conducted a systematic search of PubMed and Ovid MEDLINE to identify in vivo animal experiments that have investigated the management of S. aureus osteomyelitis in the context of fractures and metallic implants. In this review, experimental studies are categorised by animal species and are further classified by the setting of the infection. Study methods are summarised and the relevant advantages and disadvantages of each species and model are discussed. While no ideal animal model exists, the understanding of a model’s strengths and limitations should assist clinicians and researchers to appropriately select an animal model to translate the conclusions to the clinical setting.

  16. Burnout in journalists: A systematic literature review

    Jasmine B. MacDonald

    2016-06-01

    Full Text Available The present study aims to provide a concise, comprehensive, and systematic review of the quantitative literature relating to the experience of burnout in journalists of various specialties and mediums. The systematic review method adopted is that prescribed by Fink (2010, which contains three main elements: Sampling the literature, screening the literature, and extracting data. Results indicate that journalists most at risk of burnout are females who are younger, with fewer years of journalism experience, working in small circulation newspapers. Editors and reporters seem to experience higher levels of burnout than those in other roles, as do journalists in non-management positions. The thorough and structured process adopted in this review provides the ability to assert with some degree of certainty what areas within the burnout and journalism literature require further consideration. This review emphasises and problematises the large focus on male reporters in newspaper settings, settings that are becoming less significant over time. Studies have tended to focus on reporters, without providing a convincing a priori rationale. What is lacking is consideration of other role groups central to broadcast news, such as camera-operators. A range of methodological and theoretical issues and future areas of research are discussed.

    2016-01-01

    Full Text Available Objective: To collect detailed up-to-date knowledge, using a detailed systematic review of the literature, that is specific to the condition of Ekbom Syndrome, also known as Delusional Parasitosis (DP. This article will review: Historical facts, epidemiology, pathogenesis, clinical features, subtypes and related conditions, associated diseases, psychosocial impact, economic considerations and treatment. Background: DP is a psychiatric condition and can be the earliest sign of a major psychotic illness. The condition was described as early as the late 17th century in France. The etiology is neuro-chemical. The classic “matchbox” and “specimen” signs can lead to a successful diagnosis. Treatment is via a multidisciplinary approach. Methods: A detailed search strategy was utilized across six databases led by pre-specified keywords (62 in number, followed by the application of database-specific filters to scrutinize the hierarchy of literature, from guidelines, systematic reviews and randomized controlled trials to medical papers with weak evidence, including anecdotal reports. One article was translated from French. Results: Forty references were used to extract the most relevant data. This article is divided into sections of topics, starting from methodology to a conclusion. Conclusion: This review article will enable the medical researcher to obtain a detailed perspective of the condition of DP. Thus, a researcher can seek the highest available evidence from the literature and use it as a starting point for his original research.

    The nutritional quality of food and beverage products sold in vending machines has been implicated as a contributing factor to the development of an obesogenic food environment. How comprehensive, reliable, and valid are the current assessment tools for vending machines to support or refute these claims? A systematic review was conducted to summarize, compare, and evaluate the current methodologies and available tools for vending machine assessment. A total of 24 relevant research studies published between 1981 and 2013 met inclusion criteria for this review. The methodological variables reviewed in this study include assessment tool type, study location, machine accessibility, product availability, healthfulness criteria, portion size, price, product promotion, and quality of scientific practice. There were wide variations in the depth of the assessment methodologies and product healthfulness criteria utilized among the reviewed studies. Of the reviewed studies, 39% evaluated machine accessibility, 91% evaluated product availability, 96% established healthfulness criteria, 70% evaluated portion size, 48% evaluated price, 52% evaluated product promotion, and 22% evaluated the quality of scientific practice. Of all reviewed articles, 87% reached conclusions that provided insight into the healthfulness of vended products and/or vending environment. Product healthfulness criteria and complexity for snack and beverage products was also found to be variable between the reviewed studies. These findings make it difficult to compare results between studies. A universal, valid, and reliable vending machine assessment tool that is comprehensive yet user-friendly is recommended.

    Acute gout is traditionally treated with NSAIDs, corticosteroids, and colchicine; however, subjects have multiple comorbidities that limit the use of some conventional therapies. We systematically reviewed the published data on the pharmacologic and non-pharmacologic agents used for the treatment of acute gouty arthritis. A systematic search was performed using PubMed and Cochrane database through May 2013. We included only randomized controlled trials (RCTs) that included NSAIDs, corticosteroids, colchicine, adrenocorticotropic hormone (ACTH), interleukin-1 (IL-1) inhibitors, topical ice, or herbal supplements. Thirty articles were selected for systematic review. The results show that NSAIDs and COX-2 inhibitors are effective agents for the treatment of acute gout attacks. Systemic corticosteroids have similar efficacy to therapeutic doses of NSAIDs, with studies supporting oral and intramuscular use. ACTH is suggested to be efficacious in acute gout. Oral colchicine demonstrated to be effective, with low-dose colchicine demonstrating a comparable tolerability profile as placebo and a significantly lower side effect profile to high-dose colchicine. The IL-1β inhibitory antibody, canakinumab, was effective for the treatment of acute attacks in subjects refractory to and in those with contraindications to NSAIDs and/or colchicine. However, rilonacept was demonstrated to be not as effective, and there are no RCTs for the use of anakinra. NSAIDs, COX-2 selective inhibitors, corticosteroids, colchicine, ACTH, and canakinumab have evidence to suggest efficacy in treatment of acute gout. Published by Elsevier Inc.

    Over the last century, Inuit have experienced rapid social changes that have greatly impacted their way of life, health, and intergenerational traditions. Although there is a growing body of research concerning Inuit youth, relatively little is known about elderly Inuit. In an effort to bridge this knowledge gap, a systematic review of peer-reviewed journal articles was conducted. This review identified a dearth of research on older Inuit, and highlighted limitations in service provision to this primarily rural and isolated population. Implications for policy and practice and recommendations for future research are also discussed.

    Few well-defined, evidence-based nutritional recommendations for people with skin diseases have been published in the scientific literature and standard dermatological textbooks. Using a systematic review of acne vulgaris as an example, the aim of this study was to determine whether there are systematic studies on the topic and, if so, of what quality. Four evidence levels were defined: (A) double-blind randomized study; (B) randomized study with serious limitations/low number of cases; (C) case-control or cohort study; and (D) expert opinion/case report. PubMed and Cochrane searches were performed using combinations of the terms "diet", "nutrition", "meal" and "food" with "acne". Foodstuffs mentioned in relevant articles were subdivided by evidence level and recorded as having a beneficial (+), neutral (0) or adverse (-) effect. However, only a small proportion of studies met sufficiently high scientific standards that would enable therapeutic recommendations to be made in practice.

    Full Text Available Abstract Aims: Intellectual disability is a condition characterised by the inability of a person to undertake normal psychological activities. The purpose of this study was to systematically review the intellectual disability in children and discuss the implications of different environmental and genetic factors, which describe particular categories of intellectual disable cases. Information & Methods: This systematic review was performed in 2014 by searching the existing literature in PubMed database in the scope of “intellectual disability in children”. 38 articles written from 1987 to 2014 were selected and surveyed for review. Findings: The prevalence of ID in the general population is estimated to be approximately 1%. ID disorder is multi-causal, encompassing all factors that interfere with brain development and functioning. Causes usually are classified according to the time of the insult, as prenatal, perinatal, and postnatal or acquired. Some causes, such as environmental toxins or endocrine disorders, may act at multiple times. Others, such as genetic disorders, have different manifestations during postnatal development. The outcome for ID is variable and depends upon the aetiology, associated conditions, and environmental and social factors. The goals of management of ID are to strengthen areas of reduced function, minimize extensive deterioration in mental cognitive and adaptability, and lastly, to promote optimum or normal functioning of the individuals in their community. Conclusion: Prominent features of ID include significant failures in both intellectual functioning and adaptive behaviour, which comprises daily social and practical life skills, commencing earlier in life.

    Melatonin is an indolamine produced by the pineal gland and it can exert a potent antioxidant effect. Its free radical scavenger properties have been used to advantage in different organ transplants in animal experiments. Several concentrations and administration pathways have been tested and melatonin has shown encouraging beneficial results in many transplants of organs such as the liver, lungs, heart, pancreas, and kidneys. The objective of the present study was to review the scientific literature regarding the use of melatonin in ovary transplantation. A systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement was carried out using the Cochrane and Pubmed databases and employing the terms 'melatonin' AND 'ovary' AND 'transplantation.' After analysis, 5 articles were extracted addressing melatonin use in ovary transplants and involving 503 animals. Melatonin enhanced various graft aspects like morphology, apoptosis, immunological reaction, revascularization, oxidative stress, and survival rate. Melatonin's antioxidative and antiapoptotic properties seemingly produce positive effects on ovarian graft activity. Despite the promising results, further studies in humans need to be conducted to consolidate its use, as ovary transplantation for fertility preservation is gradually being moved from the experimental stage to a clinical setting.

    To systematically identify the main factors contributing to the increase in pharmaceutical expenditures. A systematic search of published studies was conducted utilising major widely used electronic databases using the search terms 'factors,' 'financing,' 'pharmaceutical,' and 'expenditures.' To be included, the studies needed to: (1) measure at least one of the following outcomes: total growth in pharmaceutical expenditures, price growth or quantity growth; (2) mention a clear method for analysing the impact of factors affecting the increases in drug expenditures; (3) be written in English. Nonprimary articles that were published only as an abstract, a review, a commentary or a letter were excluded. From a total of 2039 studies, only 25 were included in the full review. The main determinant categories that were identified in the review were factors related to price, utilisation, therapeutic choice, demand and health care system. The major cost drivers were found to be changes in drug quantities and therapies as well as new drugs. It is important for policymakers to understand pharmaceutical spending trends and the factors that influence them in order to formulate effective cost containment strategies and design optimum drug policy.

    Background and aims Out of a large number of studies on Internet addiction, only a few have been published on the prevention of Internet addiction. The aim of this study is provide a systematic review of scientific articles regarding the prevention of Internet addiction and to identify the relevant topics published in this area of interest. Methods The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were adopted. The EBSCO, ProQuest Central, and PubMed databases were searched for texts published in English and Spanish between January 1995 and April 2016. A total of 179 original texts were obtained. After de-duplication and topic-relevance review, 108 texts were systematically classified and subjected to descriptive analysis and subsequent content analysis. Results The results of the content analysis yielded the following thematic areas: (a) target groups, (b) the improvement of specific skills, (c) program characteristics, and (d) environmental interventions. Discussion and conclusion Literature on the prevention of Internet addiction is scarce. There is an urgent need to introduce and implement new interventions for different at-risk populations, conduct well-designed research, and publish data on the effectiveness of these interventions. Developing prevention interventions should primarily target children and adolescents at risk of Internet addiction but also parents, teachers, peers, and others who are part of the formative environment of children and adolescents at risk of Internet addiction. Newly designed interventions focused on Internet addiction should be rigorously evaluated and the results published.

    Mentoring, as a partnership in personal and professional growth and development, is central to academic medicine, but it is challenged by increased clinical, administrative, research, and other educational demands on medical faculty. Therefore, evidence for the value of mentoring needs to be evaluated. To systematically review the evidence about the prevalence of mentorship and its relationship to career development. MEDLINE, Current Contents, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, PsycINFO, and Scopus databases from the earliest available date to May 2006. We identified all studies evaluating the effect of mentoring on career choices and academic advancement among medical students and physicians. Minimum inclusion criteria were a description of the study population and availability of extractable data. No restrictions were placed on study methods or language. The literature search identified 3640 citations. Review of abstracts led to retrieval of 142 full-text articles for assessment; 42 articles describing 39 studies were selected for review. Of these, 34 (87%) were cross-sectional self-report surveys with small sample size and response rates ranging from 5% to 99%. One case-control study nested in a survey used a comparison group that had not received mentoring, and 1 cohort study had a small sample size and a large loss to follow-up. Less than 50% of medical students and in some fields less than 20% of faculty members had a mentor. Women perceived that they had more difficulty finding mentors than their colleagues who are men. Mentorship was reported to have an important influence on personal development, career guidance, career choice, and research productivity, including publication and grant success. Mentoring is perceived as an important part of academic medicine, but the evidence to support this perception is not strong. Practical recommendations on mentoring in

    2008-02-01

    This systematic review identified the current state of the evidence related to the prevention of obesity in young children. The results indicate five areas of emphasis in the literature: prevalence of the problem; prevention as the best option; preschool population as the target; crucial parental involvement; and numerous guidelines. Because the gap between clear articulation of the problem as well as population and the best strategies to impact the prevention of the problem is evident, health care practitioners must be involved in well-constructed implementation and evaluation studies that build on the limited base of current evidence.

  13. Is bone tissue really affected by swimming? A systematic review.

    Directory of Open Access Journals (Sweden)

    Alejandro Gómez-Bruton

    Full Text Available BACKGROUND: Swimming, a sport practiced in hypogravity, has sometimes been associated with decreased bone mass. AIM: This systematic review aims to summarize and update present knowledge about the effects of swimming on bone mass, structure and metabolism in order to ascertain the effects of this sport on bone tissue. METHODS: A literature search was conducted up to April 2013. A total of 64 studies focusing on swimmers bone mass, structure and metabolism met the inclusion criteria and were included in the review. RESULTS: It has been generally observed that swimmers present lower bone mineral density than athletes who practise high impact sports and similar values when compared to sedentary controls. However, swimmers have a higher bone turnover than controls resulting in a different structure which in turn results in higher resistance to fracture indexes. Nevertheless, swimming may become highly beneficial regarding bone mass in later stages of life. CONCLUSION: Swimming does not seem to negatively affect bone mass, although it may not be one of the best sports to be practised in order to increase this parameter, due to the hypogravity and lack of impact characteristic of this sport. Most of the studies included in this review showed similar bone mineral density values in swimmers and sedentary controls. However, swimmers present a higher bone turnover than sedentary controls that may result in a stronger structure and consequently in a stronger bone.

  14. Using text mining for study identification in systematic reviews: a systematic review of current approaches.

    The large and growing number of published studies, and their increasing rate of publication, makes the task of identifying relevant studies in an unbiased way for inclusion in systematic reviews both complex and time consuming. Text mining has been offered as a potential solution: through automating some of the screening process, reviewer time can be saved. The evidence base around the use of text mining for screening has not yet been pulled together systematically; this systematic review fills that research gap. Focusing mainly on non-technical issues, the review aims to increase awareness of the potential of these technologies and promote further collaborative research between the computer science and systematic review communities. Five research questions led our review: what is the state of the evidence base; how has workload reduction been evaluated; what are the purposes of semi-automation and how effective are they; how have key contextual problems of applying text mining to the systematic review field been addressed; and what challenges to implementation have emerged? We answered these questions using standard systematic review methods: systematic and exhaustive searching, quality-assured data extraction and a narrative synthesis to synthesise findings. The evidence base is active and diverse; there is almost no replication between studies or collaboration between research teams and, whilst it is difficult to establish any overall conclusions about best approaches, it is clear that efficiencies and reductions in workload are potentially achievable. On the whole, most suggested that a saving in workload of between 30% and 70% might be possible, though sometimes the saving in workload is accompanied by the loss of 5% of relevant studies (i.e. a 95% recall). Using text mining to prioritise the order in which items are screened should be considered safe and ready for use in 'live' reviews. The use of text mining as a 'second screener' may also be used cautiously

    Intermaxillary fixation (IMF) techniques are commonly used in mandibular fracture treatment to reduce bone fragments and re-establish normal occlusion. However, non-IMF reduction techniques such as repositioning forceps may be preferable due to their quick yet adequate reduction. The purpose of this paper is to assess which non-IMF reduction techniques and reduction forceps are available for fracture reduction in the mandible. A systematic search was performed in the databases of Pubmed and EMBASE. The search was updated until February 2016 and no initial date and language preference was set. 14 articles were selected for this review, among them ten articles related to reduction forceps and four articles describing other techniques. Thus, modification and design of reduction forceps and other reduction techniques are qualitatively described. Few designs of repositioning forceps have been proposed in the literature. Quick and adequate reduction of fractures seems possible with non-IMF techniques resulting in anatomic repositioning and shorter operation time, especially in cases with good interfragmentary stability. Further development and clinical testing of reduction forceps is necessary to establish their future role in maxillofacial fracture treatment.

    Human papillomavirus (HPV) vaccination is recommended in early adolescence, at an age when other vaccines are also recommended. Administration of multiple vaccines during one visit is an opportunity to improve uptake of adolescent vaccines. We conducted a systematic review of safety and immunogenicity of HPV vaccines coadministered with other vaccines. Our review included 9 studies, 4 of quadrivalent HPV vaccine and 5 of bivalent HPV vaccine; coadministered vaccines included: meningococcal conjugate, hepatitis A, hepatitis B, combined hepatitis A and B, tetanus, diphtheria, acellular pertussis, and inactivated poliovirus vaccines. Studies varied in methods of data collection and measurement of immunogenicity and safety. Noninferiority of immune response and an acceptable safety profile were demonstrated when HPV vaccine was coadministered with other vaccines.

    Tinnitus is considered a multi-factorial symptom. Arterial hypertension has been cited as a tinnitus etiological factor. To assess the scientific evidence on the associations between arterial hypertension and tinnitus. A systematic review was performed using PubMed, ISI Web, Lilacs and SciELO scientific databases. This review included articles published in Portuguese, Spanish, French and English correlating tinnitus with hypertension. Letters to editors and case reports were excluded. A total of 424 articles were identified, of which only 20 met the inclusion criteria. Studies that analyzed the incidence of hypertension in tinnitus patients tended to show an association, while those that evaluated the incidence of tinnitus in hypertensive patients did not. There is evidence of an association between tinnitus and hypertension, although a cause and effect relationship is uncertain. Changes in the cochlear microcirculation, resulting in hearing loss, may be an adjuvant factor in tinnitus pathophysiology.

    Results: The original search yielded 239 articles, of which 52 articles described human cases. After following the inclusion and exclusion criteria, 32 studies describing 310 cases (151 females, 175 children of human poisoning with amitraz were included in this systematic review. The most commonly reported clinical features of amitraz poisoning were altered sensorium, miosis, hyperglycaemia, bradycardia, vomiting, respiratory failure, hypotension and hypothermia. Amitraz poisoning carried a good prognosis with only six reported deaths (case fatality rate, 1.9%. Nearly 20 and 11.9 per cent of the patients required mechanical ventilation and inotropic support, respectively. The role of decontamination methods, namely, gastric lavage and activated charcoal was unclear. Interpretation & conclusions: Our review shows that amitraz is an important agent for accidental or suicidal poisoning in both adults and children. It has a good prognosis with supportive management.

    Identifying, through a systematic literature review, evidence of a possible association between obesity and dental caries. A search of articles published between 2005 and January 2012 was performed in the Medline/PubMed, LILACS and Web of Science databases. The quality of scientific evidence of the selected articles was assessed by the items proposed for observational studies in the Downs & Black instrument. Initially, 537 references were found; after checking the titles and abstracts by two independent researchers, twenty-eight articles were selected for complete reading. Ten of them that assessed the primary and/or permanent dentition observed a positive association between obesity and dental caries and one study found an inverse association. According to the Downs & Black classification, thirteen articles with good scientific evidence were found. The present review did not find sufficient evidence regarding the association between obesity and dental caries, and it did not clarify the possible role of diet and other possible effect modifiers on this association.

    There has been growing interest regarding the impact of telemonitoring and its ability to reduce the increasing burden of chronic diseases, including chronic cardiovascular disease (CVD), on healthcare systems. A number of randomised trials have been undertaken internationally and synthesised into various systematic reviews to establish an evidence base for this model of care. This study sought to synthesise and critically evaluate this large body of evidence to inform clinicians, researchers and policy makers. A systematic review of systematic reviews investigating the impact of telemonitoring interventions in the primary care management of CVD was conducted. Reviews were included if they explored primary care based telemonitoring in either CVD, heart failure or hypertension, were reported in the English language and were published between 2000 and 2013. Data was extracted by one reviewer and checked by a second reviewer using a standardised form. Two assessors then rated the quality of each review using the Overview Quality Assessment Questionnaire (OQAQ). Of the 13 included reviews, four focused on telemonitoring interventions in hypertension or CVD management and the remaining 9 reviews investigated telemonitoring in HF management. Seven reviews scored a five or above on the OQAQ evidencing good quality reviews. Findings suggest that telemonitoring can contribute to significant reductions in blood pressure, decreased all-cause and HF related hospitalisations, reduced all-cause mortality and improved quality of life. Telemonitoring was also demonstrated to reduce health care costs and appears acceptable to patients. Telemonitoring has the potential to enhance primary care management of CVD by improving patient outcomes and reducing health costs. However, further research needs to explore the specific elements of telemonitoring interventions to determine the relative value of the various elements. Additionally, the ways in which telemonitoring care improves

    Full Text Available This systematic review of the Brazilian and worldwide literature aims to evaluate the incidence and causes of perioperative and anesthesia-related mortality. Studies were identified by searching the Medline and Scielo databases, followed by a manual search for relevant articles. Our review includes studies published between 1954 and 2007. Each publication was reviewed to identify author(s, study period, data source, perioperative mortality rates, and anesthesia-related mortality rates. Thirty-three trials were assessed. Brazilian and worldwide studies demonstrated a similar decline in anesthesia-related mortality rates, which amounted to fewer than 1 death per 10,000 anesthetics in the past two decades. Perioperative mortality rates also decreased during this period, with fewer than 20 deaths per 10,000 anesthetics in developed countries. Brazilian studies showed higher perioperative mortality rates, from 19 to 51 deaths per 10,000 anesthetics. The majority of perioperative deaths occurred in neonates, children under one year, elderly patients, males, patients of ASA III physical status or poorer, emergency surgeries, during general anesthesia, and cardiac surgery followed by thoracic, vascular, gastroenterologic, pediatric and orthopedic surgeries. The main causes of anesthesia-related mortality were problems with airway management and cardiocirculatory events related to anesthesia and drug administration. Our systematic review of the literature shows that perioperative mortality rates are higher in Brazil than in developed countries, while anesthesia-related mortality rates are similar in Brazil and in developed countries. Most cases of anesthesia-related mortality are associated with cardiocirculatory and airway events. These data may be useful in developing strategies to prevent anesthesia-related deaths.

    Full Text Available The aim of this systematic review is to evaluate the role of enteral nutrition in dementia. The prevalence of dementia is predicted to rise worldwide partly due to an aging population. People with dementia may experience both cognitive and physical complications that impact on their nutritional intake. Malnutrition and weight loss in dementia correlates with cognitive decline and the progress of the disease. An intervention for long term eating difficulties is the provision of enteral nutrition through a Percutaneous Endoscopic Gastrostomy tube to improve both nutritional parameters and quality of life. Enteral nutrition in dementia has traditionally been discouraged, although further understanding of physical, nutritional and quality of life outcomes are required. The following electronic databases were searched: EBSCO Host, MEDLINE, PubMed, Cochrane Database of Systematic Reviews and Google Scholar for publications from 1st January 2008 and up to and including 1st January 2014. Inclusion criteria included the following outcomes: mortality, aspiration pneumonia, pressure sores, nutritional parameters and quality of life. Each study included separate analysis for patients with a diagnosis of dementia and/or neurological disease. Retrospective and prospective observational studies were included. No differences in mortality were found for patients with dementia, without dementia or other neurological disorders. Risk factors for poor survival included decreased or decreasing serum albumin levels, increasing age or over 80 years and male gender. Evidence regarding pneumonia was limited, although did not impact on mortality. No studies explored pressure sores or quality of life.

    Supply of medicine as a strategic product in any health system is a top priority. Pharmaceutical companies, a major player of the drug supply chain, are subject to many risks. These risks disrupt the supply of medicine in many ways such as their quantity and quality and their delivery to the right place and customers and at the right time. Therefore risk identification in the supply process of pharmaceutical companies and mitigate them is highly recommended. In this study it is attempted to investigate pharmaceutical supply chain risks with perspective of manufacturing companies. Scopus, PubMed, Web of Science bibliographic databases and Google scholar scientific search engines were searched for pharmaceutical supply chain risk management studies with 6 different groups of keywords. All results found by keywords were reviewed and none-relevant articles were excluded by outcome of interests and researcher boundaries of study within 4 steps and through a systematic method. Nine articles were included in the systematic review and totally 50 main risks based on study outcome of interest extracted which classified in 7 categories. Most of reported risks were related to supply and supplier issues. Organization and strategy issues, financial, logistic, political, market and regulatory issues were in next level of importance. It was shown that the majority of risks in pharmaceutical supply chain were internal risks due to processes, people and functions mismanagement which could be managed by suitable mitigation strategies.

    The aim of this systematic review is to evaluate the role of enteral nutrition in dementia. The prevalence of dementia is predicted to rise worldwide partly due to an aging population. People with dementia may experience both cognitive and physical complications that impact on their nutritional intake. Malnutrition and weight loss in dementia correlates with cognitive decline and the progress of the disease. An intervention for long term eating difficulties is the provision of enteral nutrition through a Percutaneous Endoscopic Gastrostomy tube to improve both nutritional parameters and quality of life. Enteral nutrition in dementia has traditionally been discouraged, although further understanding of physical, nutritional and quality of life outcomes are required. The following electronic databases were searched: EBSCO Host, MEDLINE, PubMed, Cochrane Database of Systematic Reviews and Google Scholar for publications from 1st January 2008 and up to and including 1st January 2014. Inclusion criteria included the following outcomes: mortality, aspiration pneumonia, pressure sores, nutritional parameters and quality of life. Each study included separate analysis for patients with a diagnosis of dementia and/or neurological disease. Retrospective and prospective observational studies were included. No differences in mortality were found for patients with dementia, without dementia or other neurological disorders. Risk factors for poor survival included decreased or decreasing serum albumin levels, increasing age or over 80 years and male gender. Evidence regarding pneumonia was limited, although did not impact on mortality. No studies explored pressure sores or quality of life.

    Current cardiac rehabilitation (CR) evidence was systematically evaluated to identify program components that may yield improvements in physiological and psychosocial outcomes in women. A search was conducted in the electronic databases: MEDLINE, Embase, CINAHL, Scopus, Sport Discus and Cochrane Library. Search terms included women, heart disease, exercise therapy, and cardiac rehabilitation. A systematic elimination process was used with specific inclusion/exclusion criteria. Included articles were independently evaluated by four reviewers for level of evidence and internal validity. Specific recommendations were made based on trends in the literature and strength of supporting evidence. Thirty-seven articles were included with a combined sample of 3,807 subjects. Ten studies included an analysis of physiological effects of exercise. Aerobic, resistance, and combined exercise interventions all yield physiological benefits. CR yielded favourable health-related quality of life outcomes and women benefited from psychosocial support in both formal and informal environments. The following recommendations are based on the review: 1) For patients with good cardiac function, community/home-based programs are as effective as supervised programs (Level II, B); 2) resistance training should be included as an adjunct to aerobic training (Level I, A); 3) programs need to address the specific educational needs of women (Level I, A) and a stronger emphasis needs to be placed on social support (Level II, B).

    There is abundant literature on the birth outcomes of women of Mexican origin living in the United States, but in most cases it does not refer to data available in Mexico. We conducted a systematic review of available data regarding low birthweight (LBW) rates in Mexico. We searched official online Mexican administrative data bases and four literature databases: OVID (Global Health), EMBASE, PubMed, and Bireme. The following inclusion criteria were used: (1) study is in English, Spanish, or Portuguese; (2) study presents data regarding LBW or birthweight distribution in Mexico; (3) study defines LBW as either 7.9%). States at low altitudes (<50 m) had LBW rates lower than the median, with the exception of Yucatán state. The systematic literature review identified 22 hospital-based studies and three household interview surveys that met our inclusion criteria. The hospital-based LBW rates were relatively similar to the birth certificate data and slightly lower than survey data. Data on LBW rates are available in Mexico. They should be analyzed further and used for comparative studies.

    Interactive systems are being developed with the intention to help in the engagement of patients on various therapies. Amid the recent technological advances, Kinect™ from Microsoft (Redmond, WA) has helped pave the way on how user interaction technology facilitates and complements many clinical applications. In order to examine the actual status of Kinect developments for rehabilitation, this article presents a systematic review of articles that involve interactive, evaluative, and technical advances related to motor rehabilitation. Systematic research was performed in the IEEE Xplore and PubMed databases using the key word combination "Kinect AND rehabilitation" with the following inclusion criteria: (1) English language, (2) page number >4, (3) Kinect system for assistive interaction or clinical evaluation, or (4) Kinect system for improvement or evaluation of the sensor tracking or movement recognition. Quality assessment was performed by QualSyst standards. In total, 109 articles were found in the database research, from which 31 were included in the review: 13 were focused on the development of assistive systems for rehabilitation, 3 in evaluation, 3 in the applicability category, 7 on validation of Kinect anatomic and clinical evaluation, and 5 on improvement techniques. Quality analysis of all included articles is also presented with their respective QualSyst checklist scores. Research and development possibilities and future works with the Kinect for rehabilitation application are extensive. Methodological improvements when performing studies on this area need to be further investigated.

    Penile fracture is an uncommon Urological emergency. In flaccid state it allows significant degree of deformation without any injury to the vital structures but in erected state it is vulnerable to blunt injury. The tumescent corpora cavernosa may have got injured due to nonphysiological bending of penile shaft. The true incidence of penile fracture is not known even in western countries. It is either under reported or hidden for potential social embracement. We have reviewed all of our cases of penile fracture and has been conducted a retrospective study in the Department of Urology, Bangladesh Medical College, Dhaka. The study period was from October 2001 to January 2006. The sample size was 23. All patients have got classical history of penile fracture. The time between the onset of symptom and seeking of medical care ranges from 02 hours to 07 days. The diagnosis was made on the basis of history and clinical examination only. All the patients were underwent surgery. The potency was well preserved in all of our patients. The local tissue healing process is better among the patients, reported earlier. The overall result is excellent.

    Replacement of lost teeth has significant functional and psychosocial effects. The capability of osseointegrated dental implants to transmit a certain amount of sensibility is still unclear. The phenomenon of developing a certain amount of tactile sensibility through osseointegrated dental implants is called osseoperception. The aim of this article is to evaluate the available literature to find osseoperception associated with dental implants. To identify suitable literature, an electronic search was performed using Medline and PubMed database. Articles published in English and articles whose abstract is available in English were included. The articles included in the review were based on osseoperception, tactile sensation, and neurophysiological mechanoreceptors in relation to dental implants. Articles on peri-implantitis and infection-related sensitivity were not included. Review articles without the original data were excluded, although references to potentially pertinent articles were noted for further follow-up. The phenomenon of osseoperception remains a matter of debate, so the search strategy mainly focused on articles on osseoperception and tactile sensibility of dental implants. This review presents the histological, neurophysiological, and psychophysical evidence of osseoperception and also the role of mechanoreceptors in osseoperception. The literature on osseoperception in dental implants is very scarce. The initial literature search resulted in 90 articles, of which 81 articles that fulfilled the inclusion criteria were included in this systematic review. Patients restored with implant-supported prostheses reported improved tactile and motor function when compared with patients wearing complete dentures. © 2016 by the American College of Prosthodontists.

    Full Text Available The present article aims to review the available literature on match analysis in adult male Volleyball. Specific key words "performance analysis", "match analysis", "game analysis", "notational analysis", "tactical analysis", "technical analysis", "outcome" and "skills" were used to search relevant databases (PubMed, Web of Science, SportDiscus, Academic Search Complete and the International Journal of Performance Analysis in Sport. The research was conducted according to PRISMA (Preferred Reporting Items for Systematic reviews and Meta analyses guidelines. Of 3407 studies initially identified, only 34 were fully reviewed, and their outcome measures extracted and analyzed. Studies that fit all inclusion criteria were organized into two levels of analysis, according to their research design (comparative or predictive and depending on the type of variables analyzed (skills and their relationship with success, play position and match phase. Results show that from a methodological point of view, comparative studies where currently complemented with some predictive studies. This predictive approach emerged with the aim to identify the relationship between variables, considering their possible interactions and consequently its effect on team performance, contributing to a better understanding of Volleyball game performance through match analysis. Taking into account the limitations of the reviewed studies, future research should provide comprehensive operational definitions for the studied variables, using more recent samples, and consider integrating the player positions and match phase contexts into the analysis of Volleyball.

Methods: Full articles containing original data on floorball that had been published in English in peer-reviewed journals were considered for inclusion. Results: Of 75 articles screened, 19 were included in this systematic review. One article each was identified in the fields of sports management and sports psychology, and the remaining 17 articles were in the field of sports medicine. Injury epidemiology in floorball players was the most thoroughly examined topic of research. To date, no research has been performed on the incidence of floorball-related injury, or any aspect of the sport, in children and adolescents. Conclusion: Collaborative research among sports science disciplines is needed to identify strategies to reduce the incidence of injury and enhance the performance of licensed floorball players. Despite the increasing popularity of floorball in recent years, surprisingly little research has examined this sport. Keywords: floorball, unihockey, review

    Social support is a key nursing variable. No review has yet systematically assessed the effectiveness of the personal resource questionnaire (PRQ) as a measure of perceived social support. This article reviewed nine previous studies that used the PRQ (Brandt & Weinert, 1981). Completed studies were identified through searches of indexes that included PubMed, the Cumulative Index for Nursing and EBSCO host, and Ovid. Studies that reported PRQ scores, sample descriptions, and sample sizes and that tested the relationship between the PRQ and study variables were included in the present review. Three other studies were included that did not report on PRQ correlations with other health variables. The included studies addressed a variety of health problems and different population in different settings. Cronbach's alphas for the included studies ranged from .87 to .93, supporting the internal consistency of the PRQ. Hypothesized relationships between the PRQ and study variables including health promotion behavior, self-care behavior, self-efficacy, self-esteem, stress, depression, loneliness, pain, and disability were supported, providing positive evidence for PRQ construct validity. Included studies used the PRQ to address disparate populations in terms of age, socioeconomic status, ethnicity, and educational background. This review found the PRQ to be a reliable and valid tool for measuring perceived social support across a wide range of populations. Further studies are necessary to examine the relationship between social support and selected demographics among populations with different cultural backgrounds.

    Full Text Available Fractures and displacement of fragments involving the genial tubercles due to trauma are rarely seen in patients with a full complement of teeth although spontaneous fractures of the genial tubercles in edentulous atrophic mandible are not uncommon. These are usually displaced and may be missed during routine clinical and radiographic examinations owing to superimposition of the features of a fractured mandible. Very few cases have been reported till date. Their implications lie in functional alterations that occur as a consequence of loss of attachment of the geniohyoid and genioglossus muscles. There is no universal opinion on the treatment of fractures involving the genial tubercles. Possible treatments include no surgical intervention, excision of the avulsed bone fragments, and muscular repositioning. We present a case of mandibular fracture associated with the fracture and displacement of a fragment involving the genial tubercles in a dentate patient where in the finding was incidental and a review of literature.

  20. Contribution of Systematic Reviews to Management Decisions

    2014-01-01

    Systematic reviews comprehensively summarize evidence about the effectiveness of conservation interventions. We investigated the contribution to management decisions made by this growing body of literature. We identified 43 systematic reviews of conservation evidence, 23 of which drew some concrete conclusions relevant to management. Most reviews addressed conservation interventions relevant to policy decisions; only 35% considered practical on-the-ground management interventions. The majority of reviews covered only a small fraction of the geographic and taxonomic breadth they aimed to address (median = 13% of relevant countries and 16% of relevant taxa). The likelihood that reviews contained at least some implications for management tended to increase as geographic coverage increased and to decline as taxonomic breadth increased. These results suggest the breadth of a systematic review requires careful consideration. Reviews identified a mean of 312 relevant primary studies but excluded 88% of these because of deficiencies in design or a failure to meet other inclusion criteria. Reviews summarized on average 284 data sets and 112 years of research activity, yet the likelihood that their results had at least some implications for management did not increase as the amount of primary research summarized increased. In some cases, conclusions were elusive despite the inclusion of hundreds of data sets and years of cumulative research activity. Systematic reviews are an important part of the conservation decision making tool kit, although we believe the benefits of systematic reviews could be significantly enhanced by increasing the number of reviews focused on questions of direct relevance to on-the-ground managers; defining a more focused geographic and taxonomic breadth that better reflects available data; including a broader range of evidence types; and appraising the cost-effectiveness of interventions.

    Full Text Available Abstract Background Any cartilage damage to the glenohumeral joint should be avoided, as these damages may result in osteoarthritis of the shoulder. To understand the pathomechanism leading to shoulder cartilage damage, we conducted a systematic review on the subject of articular cartilage lesions caused by traumas where non impression fracture of the subchondral bone is present. Methods PubMed (MEDLINE, ScienceDirect (EMBASE, BIOBASE, BIOSIS Previews and the COCHRANE database of systematic reviews were systematically scanned using a defined search strategy to identify relevant articles in this field of research. First selection was done based on abstracts according to specific criteria, where the methodological quality in selected full text articles was assessed by two reviewers. Agreement between raters was investigated using percentage agreement and Cohen's Kappa statistic. The traumatic events were divided into two categories: 1 acute trauma which refers to any single impact situation which directly damages the articular cartilage, and 2 chronic trauma which means cartilage lesions due to overuse or disuse of the shoulder joint. Results The agreement on data quality between the two reviewers was 93% with a Kappa value of 0.79 indicating an agreement considered to be 'substantial'. It was found that acute trauma on the shoulder causes humeral articular cartilage to disrupt from the underlying bone. The pathomechanism is said to be due to compression or shearing, which can be caused by a sudden subluxation or dislocation. However, such impact lesions are rarely reported. In the case of chronic trauma glenohumeral cartilage degeneration is a result of overuse and is associated to other shoulder joint pathologies. In these latter cases it is the rotator cuff which is injured first. This can result in instability and consequent impingement which may progress to glenohumeral cartilage damage. Conclusion The great majority of glenohumeral cartilage

Methods: With the assistance of two experienced research librarians, we searched Ovid MEDLINE/PubMed (1946 to September 12, 2013, the Cochrane Library review, and the TRIP database. The key search terms were “tiotropium and asthma.” The search was limited to human data published in English. Included in the systematic review were all randomized controlled trials that evaluated the efficacy of tiotropium in patients with asthma. The clinical trials had to be at least 4 weeks in duration and to provide adequate information on clinically appropriate end points in asthma care (eg, change in lung function, exacerbation rates, and/or ICS dosing. Data on patient characteristics, study design, outcome measures, concomitant asthma medication, and adverse events were extracted from the full text of each included individual study. Marked heterogeneity of study design precluded statistical pooling of results for a meta-analysis. Consequently, only descriptive summaries of outcomes are provided. Results: Our database search retrieved 149 citations. We found five randomized controlled trials in humans that met our criteria for inclusion in the systematic review. We also found two open-label uncontrolled trials that were considered in the discussion. Each of the five included studies met the Consolidated Standards of Reporting Trials criteria for a well-designed randomized trial. Discussion: The five clinical studies included in this systematic review focused on evaluating

    Full Text Available The objectives of this study were to characterize and clarify the relationships between the various cognitive domains affected in COPD patients and the disease itself, as well as to determine the prevalence of impairment in the various cognitive domains in such patients. To that end, we performed a systematic review using the following databases: PubMed, Scopus, and ScienceDirect. We included articles that provided information on cognitive impairment in COPD patients. The review of the findings of the articles showed a significant relationship between COPD and cognitive impairment. The most widely studied cognitive domains are memory and attention. Verbal memory and learning constitute the second most commonly impaired cognitive domain in patients with COPD. The prevalence of impairment in visuospatial memory and intermediate visual memory is 26.9% and 19.2%, respectively. We found that cognitive impairment is associated with the profile of COPD severity and its comorbidities. The articles reviewed demonstrated that there is considerable impairment of the cognitive domains memory and attention in patients with COPD. Future studies should address impairments in different cognitive domains according to the disease stage in patients with COPD.

    Recent studies on cashew nut allergy suggest that the prevalence of cashew nut allergy is increasing. Cashew nut consumption by allergic patients can cause severe reactions, including anaphylaxis. This review summarizes current knowledge on cashew nut allergy to facilitate timely clinical recognition and to promote awareness of this emerging food allergy amongst clinicians. The goal of this study is to present a systematic review focused on the clinical aspects of allergy to cashew nut including the characteristics of cashew nut, the prevalence, allergenic components, cross-reactivity, diagnosis and management of cashew nut allergy. The literature search yielded 255 articles of which 40 met our selection criteria and were considered to be relevant for this review. The 40 articles included one prospective study, six retrospective studies and seven case reports. The remaining 26 papers were not directly related to cashew nut allergy. The literature suggests that the prevalence of cashew nut allergy is increasing, although the level of evidence for this is low. A minimal amount of cashew nut allergen may cause a severe allergic reaction, suggesting high potency comparable with other tree nuts and peanuts. Cashew allergy is clearly an underestimated important healthcare problem, especially in children.

    The purpose of this review was to systematically evaluate the literature on the efficacy of triterpenes for wound healing. We searched for original studies in the Medline, SCIDIRECT and LILACS databases published from 1910 to 2013. For each study, the title, abstract and full article were evaluated by two reviewers. We identified 2181 studies; however, after application of the inclusion and exclusion criteria, only 12 studies were subjected to further review. In surgical wounds, the triterpenes induced a reduction in time to closure, and this effect was reported in virtually all wound types. Triterpenes also modulate the production of ROS in the wound microenvironment, accelerating the process of tissue repair. Triterpenes may also induce cell migration, cell proliferation and collagen deposition. Although the pharmacological effects of triterpenes are well characterized, little is known about their effects in cells involved in healing, such as keratinocytes and fibroblasts. In addition, the lack of studies on the risks associated with the therapeutic use of triterpenes is worrisome. Our study reveals that triterpenes seem to favor wound healing; however, toxicological studies with these compounds are required. Taken together, these findings show that the triterpenes are a class of molecules with significant promise that leads for the development of new drugs to treat skin injury.

    Brands build relationships between consumers and products, services, or lifestyles by providing beneficial exchanges and adding value to their objects. Brands can be measured through associations that consumers hold for products and services. Public health brands are the associations that individuals hold for health behaviors, or lifestyles that embody multiple health behaviors. We systematically reviewed the literature on public health brands; developed a methodology for describing branded health messages and campaigns; and examined specific branding strategies across a range of topic areas, campaigns, and global settings. We searched the literature for published studies on public health branding available through all relevant, major online publication databases. Public health branding was operationalized as any manuscripts in the health, social science, and business literature on branding or brands in health promotion marketing. We developed formalized decision rules and applied them in identifying articles for review. We initially identified 154 articles and reviewed a final set of 37, 10 from Africa, Australia, and Europe. Branded health campaigns spanned most of the major domains of public health and numerous communication strategies and evaluation methodologies. Most studies provided clear information on planning, development, and evaluation of the branding effort, while some provided minimal information. Branded health messages typically are theory based, and there is a body of evidence on their behavior change effectiveness, especially in nutrition, tobacco control, and HIV/AIDS. More rigorous research is needed, however, on how branded health messages impact specific populations and behaviors.

    In adolescence, the number of depressive symptoms is rising notably. Individuals may have relevant depressive symptoms without meeting the full criteria of a major depressive episode (MDE), a condition referred to as subthreshold depression (sD). This article presents a review on adolescent sD examining the prevalence, the quality of life (QoL), the risk of developing MDE, and preventive programs available for adolescents living with sD. A systematic literature search from the year of the introduction of Diagnostic and Statistic Manual for Mental Disorders Fourth Edition (DSM-IV) until 2012 (18 years) was conducted with a special focus on adolescent sD. Data from 27 studies were included into this review. The results show high prevalence of sD among adolescents, with a negative impact on QoL, and provide evidence that sD is a significant risk indicator of later MDE; therefore, individuals with sD represent good targets for preventive interventions. Our review highlights the fact that sD is a significant health problem among adolescents indeed, and adolescents with sD could be a subgroup of youth, who need further help to reduce their clinically significant depressive symptoms for the successful prevention of a later MDE.

  10. What is open peer review? A systematic review

    Ross-Hellauer, Tony

    2017-01-01

    Background: “Open peer review” (OPR), despite being a major pillar of Open Science, has neither a standardized definition nor an agreed schema of its features and implementations. The literature reflects this, with a myriad of overlapping and often contradictory definitions. While the term is used by some to refer to peer review where the identities of both author and reviewer are disclosed to each other, for others it signifies systems where reviewer reports are published alongside articles. For others it signifies both of these conditions, and for yet others it describes systems where not only “invited experts” are able to comment. For still others, it includes a variety of combinations of these and other novel methods. Methods: Recognising the absence of a consensus view on what open peer review is, this article undertakes a systematic review of definitions of “open peer review” or “open review”, to create a corpus of 122 definitions. These definitions are then systematically analysed to build a coherent typology of the many different innovations in peer review signified by the term, and hence provide the precise technical definition currently lacking. Results: This quantifiable data yields rich information on the range and extent of differing definitions over time and by broad subject area. Quantifying definitions in this way allows us to accurately portray exactly how  ambiguously the phrase “open peer review”  has been used thus far, for the literature offers a total of 22 distinct configurations of seven traits, effectively meaning that there are 22 different definitions of OPR in the literature. Conclusions: Based on this work, I propose a pragmatic definition of open peer review as an umbrella term for a number of overlapping ways that peer review models can be adapted in line with the ethos of Open Science, including making reviewer and author identities open, publishing review reports and enabling greater participation in the

    Full Text Available Objective: To systematically identify the various methods of speed management and their effects. Methods: A systematic search was performed in Science Direct, Ovid Medline, Scopus, PubMed and ProQuest databases from April to June 2015. Hand searching and reference of selected articles were used to improve article identification. Articles published after 1990 which had reported on efficacy/effectiveness of speed management strategies were included. Data were extracted using pre-defined extraction table. Results: Of the 803 retrieved articles, 22 articles were included in this review. Most of the included articles (63% had before-after design and were done in European countries. Speed cameras, engineering schemes, intelligent speed adaption (ISA, speed limits and zones, vehicle activated sign and integrated strategies were the most common strategies reported in the literature. Various strategies had different effects on mean speed of the vehicles ranging from 1.6 to 10 km/h. Moreover, 8-65% and 11-71% reduction was reported in person injured accidents and fatal accidents, respectively as a result of employing various strategies. Conclusion: Literature revealed positive effects of various speed management strategies. Using various strategies was mostly dependent on road characteristics, driver’s attitude about the strategy as well as economic and technological capabilities of the country. Political support is considered as a main determinant in selecting speed management strategies.

    Full Text Available Background: Eye Movement Desensitization and Reprocessing (EMDR is a psychotherapeutic approach that has demonstrated efficacy in the treatment of Post-traumatic Stress Disorder (PTSD through several randomized controlled trials (RCT. Solid evidence shows that traumatic events can contribute to the onset of severe mental disorders and can worsen their prognosis. The aim of this systematic review is to summarize the most important findings from RCT conducted in the treatment of comorbid traumatic events in psychosis, bipolar disorder, unipolar depression, anxiety disorders, substance use disorders, and chronic back pain.Methods: Using PubMed, ScienceDirect, and Scopus, we conducted a systematic literature search of RCT studies published up to December 2016 that used EMDR therapy in the mentioned psychiatric conditions.Results: RCT are still scarce in these comorbid conditions but the available evidence suggests that EMDR therapy improves trauma-associated symptoms and has a minor effect on the primary disorders by reaching partial symptomatic improvement.Conclusions: EMDR therapy could be a useful psychotherapy to treat trauma-associated symptoms in patients with comorbid psychiatric disorders. Preliminary evidence also suggests that EMDR therapy might be useful to improve psychotic or affective symptoms and could be an add-on treatment in chronic pain conditions.

    In the evolving digital age, media applications are increasingly playing a greater role in the field of psychotherapy. While the Internet is already in the phase of being established when it comes to the care of mental disorders, experimentation is going on with other modern media such as serious games. A serious game is a game in which education and behavior change is the goal, alongside with entertainment. The objective of the present article was to provide a first empirical overview of serious games applied to psychotherapy and psychosomatic rehabilitation. Therefore, a systematic literature search, including the terms "serious game" or "computer game" and "psychotherapy" or "rehabilitation" or "intervention" or "mental disorders" in the databases Medline and PsycINFO, was performed. Subsequently, an Internet search was conducted to identify studies not published in journals. Publications not providing empirical data about effectiveness were excluded. On the basis of this systematic literature review, the results of N = 15 studies met inclusion criteria. They utilized primarily cognitive behavioral techniques and can be useful for treating a range of mental disorders. Serious games are effective both as a stand-alone intervention or part of psychotherapy and appeal to patients independent of age and sex. Included serious games proved to be an effective therapeutic component. Nonetheless, findings are not conclusive and more research is needed to further investigate the effectiveness of serious games for psychotherapeutic purposes.

    To describe the frequency of rheuma­tic diseases in Portugal through a systematic review of published literature, critically appraising available information and identifying data collection gaps. We systematically reviewed the literature to retrieve data on the occurrence of rheumatic diseases in Portugal through MEDLINE and Índex das Revistas Médicas Portuguesas searches, PhD theses, and national health surveys reports. Original articles in English or Portuguese published between 1 January 2000 and 31 December 2010 were included. We retrieved information for the prevalence of rheumatic diseases, osteoarthritis, back pain, work-related musculoskeletal disorders (WRMDs), osteoporosis, fibromyalgia, rheumatoid arthritis, spondyloarthritis and other systemic rheumatic diseases and for the incidence of back pain, osteoporotic fracture and other systemic rheumatic diseases. The prevalence of rheumatic diseases ranged from 16.0% to 24.0% and the prevalence of osteoarthritis was 11.1% (95% confidence intervals (95%CI): 9.4-13.1) in the knee and 5.5% (95%CI: 4.3-7.0) in the hip. Regarding back pain, period prevalence ranged from 8.0% (95%CI: 6.1-10.1) to 29.5% (95%CI: 23.4-36.2) in children and from 12.3% (95%CI: 10.5-14.3) to 51.3% (95%CI: 48.6-53.9) in adults. The prevalence of WRMDs ranged from 5.9% to 84.2% (95%CI: 80.8-87.3). The yearly incidence of osteoporotic fracture (per 100 000) ranged from 93.3 to 481 (95%CI: 407-564) in women and from 31.9 to 154 (95%CI: 106-218) in men. The prevalence of osteoporosis in women ranged from 11.0% to 15.4% (95%CI: 13.4-17.6) and in men from 1.1% to 16.8% (95%CI: 12.2-22.3). The prevalence of fibromyalgia ranged from 3.6% (95%CI: 2.0-5.2) to 3.7% (95%CI: 2.0-5.4). The prevalence estimates of ankylosing spondylitis and of spondyloarthritis were 0.6% and 1.6% (95%CI: 0.8-2.7), respectively. The prevalence of systemic lupus erythematosus was estimated in 0.2% (95%CI: 0.1-0.8). There is a broad spectrum of information available

  15. Religion and Suicide Risk: A Systematic Review.

    2016-01-01

    Although religion is reported to be protective against suicide, the empirical evidence is inconsistent. Research is complicated by the fact that there are many dimensions to religion (affiliation, participation, doctrine) and suicide (ideation, attempt, completion). We systematically reviewed the literature on religion and suicide over the last 10 years (89 articles) with a goal of identifying what specific dimensions of religion are associated with specific aspects of suicide. We found that religious affiliation does not necessarily protect against suicidal ideation, but does protect against suicide attempts. Whether religious affiliation protects against suicide attempts may depend on the culture-specific implications of affiliating with a particular religion, since minority religious groups can feel socially isolated. After adjusting for social support measures, religious service attendance is not especially protective against suicidal ideation, but does protect against suicide attempts, and possibly protects against suicide. Future qualitative studies might further clarify these associations.

All publications on TaTME were included with the exception of review articles. RESULTS: A total of 29 studies (336...... patients) were included. Only low-quality evidence is available, and the literature consists of case reports and case series. Studies represent the initial experience of surgeons/centres. No precise indication for TaTME is yet specified other than the presence of mid and low rectal tumours, although...... the potential advantages seem to be related to a bulky mesorectum in the male pelvis. The preliminary results are encouraging and the most serious complication is urethral injury. The oncological results are acceptable, although the follow-up is short. CONCLUSION: TaTME is a feasible approach for mid and low...

    2016-12-01

    This study systematically reviewed the evidence for personality as a correlate of body image. Electronic databases and reference lists were searched in May 2016 for studies reporting an association between at least one dimension of personality and at least one component of negative body image. Twenty-six studies (33 discrete samples) met inclusion criteria. Sixteen samples were coded as medium-high quality. The results indicated that negative body image was associated with higher levels of Neuroticism and lower levels of Extraversion. Agreeableness was not related to body image, and findings for Conscientiousness and Openness were indeterminate. After taking study quality into account, negative body image was also associated with lower levels of Conscientiousness. Neuroticism was associated with negative body image in both women and men. Sex moderation effects for Extraversion, Openness, and Conscientiousness were indeterminate. Large-sample, prospective studies of personality and body image are recommended.

    Full Text Available BACKGROUND: The SARS outbreak of 2002-2003 presented clinicians with a new, life-threatening disease for which they had no experience in treating and no research on the effectiveness of treatment options. The World Health Organization (WHO expert panel on SARS treatment requested a systematic review and comprehensive summary of treatments used for SARS-infected patients in order to guide future treatment and identify priorities for research. METHODS AND FINDINGS: In response to the WHO request we conducted a systematic review of the published literature on ribavirin, corticosteroids, lopinavir and ritonavir (LPV/r, type I interferon (IFN, intravenous immunoglobulin (IVIG, and SARS convalescent plasma from both in vitro studies and in SARS patients. We also searched for clinical trial evidence of treatment for acute respiratory distress syndrome. Sources of data were the literature databases MEDLINE, EMBASE, BIOSIS, and the Cochrane Central Register of Controlled Trials (CENTRAL up to February 2005. Data from publications were extracted and evidence within studies was classified using predefined criteria. In total, 54 SARS treatment studies, 15 in vitro studies, and three acute respiratory distress syndrome studies met our inclusion criteria. Within in vitro studies, ribavirin, lopinavir, and type I IFN showed inhibition of SARS-CoV in tissue culture. In SARS-infected patient reports on ribavirin, 26 studies were classified as inconclusive, and four showed possible harm. Seven studies of convalescent plasma or IVIG, three of IFN type I, and two of LPV/r were inconclusive. In 29 studies of steroid use, 25 were inconclusive and four were classified as causing possible harm. CONCLUSIONS: Despite an extensive literature reporting on SARS treatments, it was not possible to determine whether treatments benefited patients during the SARS outbreak. Some may have been harmful. Clinical trials should be designed to validate a standard protocol for dosage

    Pertuzumab is a monoclonal antibody that represents the first among a new class of agents known as human epidermal growth factor receptor (HER) dimerization inhibitors. This is the first systematic review according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to synthesize all available data of pertuzumab in breast cancer. The search strategy retrieved 11 studies that evaluated pertuzumab. One study was conducted in the neoadjuvant setting (417 patients), whereas all the others dealt with patients with recurrent, metastatic, or refractory disease (1023 patients). Six studies were conducted in HER2(+) breast cancer population (1354 patients), whereas 5 studies (86 patients) were conducted in HER2(-) (or unknown HER2 status) disease. Pertuzumab is the most recent agent approved by the US Food and Drug Administration in combination with trastuzumab and docetaxel for the treatment of patients with HER2(+) metastatic breast cancer who have not received prior anti-HER2 therapy or chemotherapy for metastatic disease. This approval has been based on data from a phase III Clinical Evaluation of Pertuzumab and Trastuzumab (CLEOPATRA) study. The antitumor activity with the significant reduction in the risk of progression or death, as reflected upon the increase of 6.1 months in median progression-free survival, indicates that pertuzumab may provide an avenue for achieving additional benefit for patients with HER2(+). Moreover, pertuzumab seems to have a putative role in the management of patients with HER2 who are resistant to trastuzumab. The promising role of pertuzumab in the neoadjuvant and adjuvant settings remains to be further investigated and established in the future.

    2015-01-01

    Laryngeal endoscopy with stroboscopy (LES) remains the clinical gold standard for assessing vocal fold function. LES is used to evaluate the efficacy of voice treatments in research studies and clinical practice. LES as a voice treatment outcome tool is only as good as the clinician interpreting the recordings. Research using LES as a treatment outcome measure should be evaluated based on rater methodology and reliability. The purpose of this literature review was to evaluate the rater-related methodology from studies that use stroboscopic findings as voice treatment outcome measures. Systematic literature review. Computerized journal databases were searched for relevant articles using terms: stroboscopy and treatment. Eligible articles were categorized and evaluated for the use of rater-related methodology, reporting of number of raters, types of raters, blinding, and rater reliability. Of the 738 articles reviewed, 80 articles met inclusion criteria. More than one-third of the studies included in the review did not report the number of raters who participated in the study. Eleven studies reported results of rater reliability analysis with only two studies reporting good inter- and intrarater reliability. The comparability and use of results from treatment studies that use LES are limited by a lack of rigor in rater methodology and variable, mostly poor, inter- and intrarater reliability. To improve our ability to evaluate and use the findings from voice treatment studies that use LES features as outcome measures, greater consistency of reporting rater methodology characteristics across studies and improved rater reliability is needed.

    2014-10-01

    Physical activity (PA) is associated with numerous health-related benefits among adults with chronic diseases and the general population. As the benefits are dose-dependent, this review aims to establish the PA levels of adults with spondyloarthritis and to compare these to the general population. Electronic databases (Cochrane Central Register of Controlled Trials, EMBASE, MEDLINE\\/PubMed, PEDro, AMED, CINAHL) were systematically searched from inception to May 2014 using medical subject headings and keywords. This was supplemented by searching conference abstracts and hand-searching reference lists of included studies. Eligible studies were randomized controlled trials and observational studies of adults with SpA in which free-living PA or energy expenditure levels were measured. Subjects less than 18 years or with juvenile-onset SpA were excluded. Outcomes included objective and self-report measurements. Two reviewers independently screened studies for inclusion and assessed methodological quality using the Cochrane risk of bias tool and the RTI item bank. From the 2,431 records reviewed, nine studies involving 2,972 participants were included. This review focused on qualitative synthesis. Meta-analyses were not undertaken due to differences in study design, measurement tools, and participant characteristics. This heterogeneity, coupled with the risk of bias inherent in the included observational studies, limits the generalizability of findings. Objective measurements suggest PA levels may be lower among adults with spondyloarthritis than in healthy population controls. Self-reported PA and self-reported rates of adherence to PA recommendations varied largely across studies; higher disease activity was associated with lower self-reported PA levels. Physical activity levels may be lower in adults with axial spondyloarthritis, with higher disease activity associated with lower PA levels.

    Background: The therapy of proximal humeral fractures (PHFs) in adults, especially for 3- or 4-part fractures, is still uncertain for traumatology surgeon. Objective: The aim of the study is to systematically review the outcomes of locking proximal humerus plate/proximal humeral internal locking system (LPHP/PHILOS) versus shoulder hemiarthroplasty for the treatment of PHFs in adults. Methods: According to Cochrane systematic review, Cochrane library, Medline, Embase, CNKI, VIP and Chinese Biomedi-cal Database were retrieved for randomized controlled trials (RCTs), Quasi-RCTs and Non-RCTs comparing relevant interventions for the treatment of PHFs with LPHP/PHILOS versus shoulder hemiarthroplasty in adults. Results: Seven Non-RCTs and one Quasi-RCTs were included in this systematic review. For methodology quality, all of them were C-scale trials. There were no significant differences in the excellent and good rates of Neer between LPHP/PHILOS and shoulder hemiarthroplasty (OR=1.27, 95%CI: [0.34, 4.71], P=0.72). Neither were the incidences of complications and secondary operation between the two methods. Conclusions: There are pro and con in the treatment of PHFs by LPHP/PHILOS or shoulder hemiarthroplasty. For the elderly patients of PHFs (≥75years, 3 or 4-part fractures), most surgeons prefers shoulder hemiarthroplasty. The current literature offers no robust evidence to support LPHP/PHILOS is superior to shoulder hemiarthroplasty for PHFs.%背景:成人肱骨近端骨折,尤其是三、四部分骨折,采用何种治疗方案仍有争论.目的:对采用肱骨近端锁定接骨板/肱骨近端内锁定系统(LPHP/PHILOS)与人工肱骨头置换治疗成年人肱骨近端骨折(proximal humeral fracture,PHF)的临床疗效进行系统评价.方法:检索Ovid Medline和PubMed(2001年1月至2011年12月)、Embase (2001年1月至2011年12月)、Cochrane Central Register of Controlled Trials (2011年)、中国生物医学文献数据库(CBM,2001年1月至2011年12

    Some of the gastrointestinal (GI) symptoms commonly experienced by patients with Parkinson's disease (PD) have been attributed to gastroparesis; however, the precise prevalence and relevance of gastric emptying delay in PD is unclear. The definition of gastroparesis varies; currently the most widely accepted definition (from the National Institute of Diabetes and Digestive and Kidney Diseases Gastroparesis Clinical Research Consortium) is the presence of appropriate symptoms (including nausea, retching, vomiting, stomach fullness, and inability to finish a meal) for ≥ 12 weeks, together with delayed gastric emptying on scintigraphy and the absence of any obstructive lesions on upper GI endoscopy. In PD patients, gastroparesis has the potential to affect nutrition and quality of life, as well as the absorption of PD medications, including L-dopa. This reduced absorption of L-dopa has implications for the control of the PD motor symptoms for which it is administered. We performed a systematic review of the literature on gastroparesis in PD with the aim of developing an evidence-based approach to its management. Based on this review, we conclude that while gastric emptying has been reported to be frequently delayed in PD, the existing data do not permit definitive conclusions concerning its true prevalence, relationship to the underlying disease process, relevance to PD management, or the optimal therapy of related GI symptoms. Further study of these important issues is, therefore, required.

    OBJECTIVE To review the frequency of and factors associated with fetal death in the Brazilian scientific literature. METHODS A systematic review of Brazilian studies on fetal deaths published between 2003 and 2013 was conducted. In total, 27 studies were analyzed; of these, 4 studies addressed the quality of data, 12 were descriptive studies, and 11 studies evaluated the factors associated with fetal death. The databases searched were PubMed and Lilacs, and data extraction and synthesis were independently performed by two or more examiners. RESULTS The level of completeness of fetal death certificates was deficient, both in the completion of variables, particularly sociodemographic variables, and in defining the underlying causes of death. Fetal deaths have decreased in Brazil; however, inequalities persist. Analysis of the causes of death indicated maternal morbidities that could be prevented and treated. The main factors associated with fetal deaths were absent or inadequate prenatal care, low education level, maternal morbidity, and adverse reproductive history. CONCLUSIONS Prenatal care should prioritize women that are most vulnerable (considering their social environment or their reproductive history and morbidities) with the aim of decreasing the fetal mortality rate in Brazil. Adequate completion of death certificates and investment in the committees that investigate fetal and infant deaths are necessary. PMID:25902565

    Toxocariasis is an important neglected tropical disease that can manifest as visceral or ocular larva migrans, or covert toxocariasis. All three forms pose a public health problem and cause significant morbidity in areas of high prevalence. To determine the burden of toxocariasis in North America, we conducted a systematic review of the literature following PRISMA guidelines. We found 18 articles with original prevalence, incidence, or case data for toxocariasis. Prevalence estimates ranged from 0.6% in a Canadian Inuit community to 30.8% in Mexican children with asthma. Commonly cited risk factors included: African-American race, poverty, male sex, and pet ownership or environmental contamination by animal feces. Increased prevalence of Toxocara spp. infection was linked in a group of case control studies conducted in Mexico to several high risk groups including waste pickers, asthmatic children, and inpatient psychiatry patients. Further research is needed to determine the true current burden of toxocariasis in North America; however the prevalence estimates gathered in this review suggest that the burden of disease is significant.

    Full Text Available Objective. This systematic review aimed to assess the effectiveness and safety of acupuncture for lateral epicondylitis (LE. Methods. Seven databases and the WHO International Clinical Trials Registry Platform Search Portal were searched to identify relevant studies. The data were extracted and assessed by two independent authors, and Review Manager Software (V.5.3 was used for data synthesis with effect estimate presented as standard mean difference (SMD and mean difference (MD with a 95% confidence interval. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE was used to assess the level of evidence. Results. Four RCTs with 309 participants were included with poor methodological quality. Participants who received acupuncture and acupuncture plus moxibustion with material insulation were likely to have an improvement in elbow functional status and/or myodynamia. The overall quality rated by GRADE was from very low to low. Two studies reported that the needle pain would be the main reason for the dropout. Conclusion. For the small number of included studies with poor methodological quality, no firm conclusion can be drawn regarding the effect of acupuncture of elbow functional status and myodynamia for LE.

    Biofeedback potentially provides non-invasive, effective psychophysiological interventions for psychiatric disorders. The encompassing purpose of this review was to establish how biofeedback interventions have been used to treat select psychiatric disorders [anxiety, autistic spectrum disorders, depression, dissociation, eating disorders, schizophrenia and psychoses] to date and provide a useful reference for consultation by clinicians and researchers planning to administer a biofeedback treatment. A systematic search of EMBASE, MEDLINE, PsycINFO, and WOK databases and hand searches in Applied Psychophysiology and Biofeedback, and Journal of Neurotherapy, identified 227 articles; 63 of which are included within this review. Electroencephalographic neurofeedback constituted the most investigated modality (31.7%). Anxiety disorders were the most commonly treated (68.3%). Multi-modal biofeedback appeared most effective in significantly ameliorating symptoms, suggesting that targeting more than one physiological modality for bio-regulation increases therapeutic efficacy. Overall, 80.9% of articles reported some level of clinical amelioration related to biofeedback exposure, 65.0% to a statistically significant (p biofeedback interventions within mainstream psychiatry.

    Headache is very common in pituitary disease and is reported to be present in more than a third of all patients with pituitary adenomas. Tumour size, cavernous sinus invasion, traction or displacement of intracranial pain-sensitive structures such as blood vessels, cranial nerves and dura mater, and hormonal hypersecretion are implicated causes. The present review attempts to systematically review the literature for any combination of headache and pituitary or hormone overproduction or deficiency. Most data available are retrospective and/or not based on the International Headache Society (IHS) classification. Whereas in pituitary apoplexy a mechanical component explains the almost universal association of the condition with headaches, this correlation is less clear in other forms of pituitary disease and a positive impact of surgery on headaches is not guaranteed. Similarly, invasion into the cavernous sinus or local inflammatory changes have been linked to headaches without convincing evidence. Some studies suggest that oversecretion of GH and prolactin may be important for the development of headaches, and treatment, particularly with somatostatin analogues, has been shown to improve symptoms in these patients. Otherwise, treatment rests on general treatment options for headaches based on an accurate clinical history and a precise classification which includes assessment of the patient's psychosocial risk factors.

    2015-06-01

    Full Text Available The idea of a sustainable agriculture has gained prominence since the publication of the Brundtland Report in 1987. Yet, the concept of sustainable agriculture is very vague and ambiguous in its meaning, which renders its use and implementation extremely difficult. In this systematic review paper, we aim to advance understandings of sustainable agriculture from a social science and governance perspective by identifying areas of complementarity and concern between emerging definitions of sustainable agriculture. For this purpose, we conducted a structured literature review in combination with a cluster analysis in order to (1 identify the overall ideas and aspects associated with sustainable agriculture; (2 detect patterns and differences in how these ideas and aspects are adopted or applied; (3 evaluate how the different ideas and aspects of sustainable agriculture are combined in the scientific debate, and assess whether these different conceptions match with those that have been claimed to exist in the debate. There are two valuable outcomes from this research. The first is a framework for understanding the components of sustainable agriculture. The second outcome is in highlighting ways for actors involved with sustainable agriculture to deal with the complexity and multiplicity of this concept in a constructive manner.

  12. A systematic review of antiproton radiotherapy

    Martin-Immanuel eBittner

    2014-01-01

    Full Text Available Antiprotons have been proposed as possible particles for radiotherapy; over the past years, the renewed interest in the potential biomedical relevance led to an increased research activity. It is the aim of this review to deliver a comprehensive overview regarding the evidence accumulated so far, analysing the background and depicting the current status of antiprotons in radiotherapy. A literature search has been conducted, including major scientific and commercial databases. All articles and a number of relevant conference abstracts published in the respective field have been included in this systematic review. The physical basis of antiproton radiotherapy is complex; however, the characterisation of the energy deposition profile supports its potential use in radiotherapy. Also the dosimetry improved considerably over the past few years. Regarding the biological properties, data on the effects on cells are presented; however, definite conclusions regarding the relative biological effectiveness cannot be made at the moment and radiobiological evidence of enhanced effectiveness remains scarce. In addition, there is new evidence supporting the potential imaging properties, for example for online dose verification. Clinical settings which might profit from the use of antiprotons have been further tracked. Judging from the evidence available so far, clinical constellations requiring optimal sparing in the entrance region of the beam and re-irradiations might profit most from antiproton radiotherapy. While several open questions remain to be answered, first steps towards a thorough characterisation of this interesting modality have been made.

    Floods are the most common type of disaster globally, responsible for almost 53,000 deaths in the last decade alone (23:1 low- versus high-income countries). This review assessed recent epidemiological evidence on the impacts of floods on human health. Published articles (2004-2011) on the quantitative relationship between floods and health were systematically reviewed. 35 relevant epidemiological studies were identified. Health outcomes were categorized into short- and long-term and were found to depend on the flood characteristics and people's vulnerability. It was found that long-term health effects are currently not well understood. Mortality rates were found to increase by up to 50% in the first year post-flood. After floods, it was found there is an increased risk of disease outbreaks such as hepatitis E, gastrointestinal disease and leptospirosis, particularly in areas with poor hygiene and displaced populations. Psychological distress in survivors (prevalence 8.6% to 53% two years post-flood) can also exacerbate their physical illness. There is a need for effective policies to reduce and prevent flood-related morbidity and mortality. Such steps are contingent upon the improved understanding of potential health impacts of floods. Global trends in urbanization, burden of disease, malnutrition and maternal and child health must be better reflected in flood preparedness and mitigation programs. Crown Copyright © 2012.

    Elevated vascular endothelial growth factor (VEGF) blood concentration reflects its prostatic production, making this a potentially interesting tumour marker to support the decision of submitting a patient for prostatic biopsy. The objective was to review systematically the evidence on the role of VEGF blood concentration in prostate cancer detection. Published studies addressing the relation between serum or plasma VEGF levels and prostate cancer were identified by searching Pubmed, ISI Web of Knowledge, SCOPUS and LILACS up to January 2010, and reviewed following a standardized protocol. Three studies reported higher plasma VEGF (pg/ml) in patients with localized prostate cancer than in healthy controls (7.0 vs. 0.0, 9.9 vs. 2.2, and 210 vs. 26.5, Pprostate cancer patients than in patients with benign prostate hypertrophy (518.9 vs. 267.9, Pbenign prostate hypertrophy, localized or metastatic prostate cancer. The three studies that used controls with previous suspicion of prostatic cancer but a negative biopsy reported non-statistically significant difference in VEGF serum levels (pg/ml) between controls and localized prostate cancer patients (241 vs. 206; 69.5 vs. 55; 215.2 vs. 266.4). Higher VEGF plasma levels are observed in prostatic cancer patients compared with healthy controls, but serum levels do not appear to be useful in differentiating benign from malignant prostatic disease using, as controls, individuals with high risk of prostate cancer and negative biopsy.

  15. Creativity and psychopathology: a systematic review.

    2014-01-01

    The possible link between creativity and psychopathology has been a long-time focus of research up to the present day. However, the research results in this field are heterogeneous and contradictory. Links between creativity and specific psychiatric disorders have been confirmed and refuted in different studies. This disparity is partly explained by the methodological challenges peculiar to this field. In this systematic review of the literature from 1950, research articles in the field of creativity and psychopathology are presented, focusing on the methodology and results of the collected studies. This review confirms the methodological problems and the heterogeneity of the study designs and results. The assessment of psychopathology, but more so of creativity, remains a fundamental challenge. On the whole, study results cautiously confirm an association between creativity and both bipolar disorder and schizotypy. The research on creativity and psychopathology is hampered by serious methodological problems. Study results are to be interpreted with caution and future research needs more methodological rigor. © 2014 S. Karger AG, Basel.

    Full Text Available OBJECTIVE Identifying, through a systematic literature review, evidence of a possible association between obesity and dental caries. METHODS A search of articles published between 2005 and January 2012 was performed in the Medline/PubMed, LILACS and Web of Science databases. The quality of scientific evidence of the selected articles was assessed by the items proposed for observational studies in the Downs & Black instrument. RESULTS Initially, 537 references were found; after checking the titles and abstracts by two independent researchers, twenty-eight articles were selected for complete reading. Ten of them that assessed the primary and/or permanent dentition observed a positive association between obesity and dental caries and one study found an inverse association. According to the Downs & Black classification, thirteen articles with good scientific evidence were found. CONCLUSIONS The present review did not find sufficient evidence regarding the association between obesity and dental caries, and it did not clarify the possible role of diet and other possible effect modifiers on this association.

    2014-01-01

    The number of intervention studies designed to improve quality of care is increasing exponentially, making it difficult to access all available information on a given subject. Systematic reviews are tools that provide health professionals with comprehensive and objective information. This article describes the main phases of a systematic review: formulating the research question, search and selection of studies, data extraction and analysis, assessment of the methodological quality of studies, and synthesis of the results. Interventions designed to improve professional practices and organisation of care have specific characteristics that determine the methodology of systematic reviews. For example, the often substantial heterogeneity between populations, organisations, and intervention settings among studies must be taken into account, which makes meta-analysis more difficult. Knowledge on specific features of systematic reviews designed to improve quality of care is essential to ensure a good review of the literature, or to evaluate the level of evidence of published systematic reviews.

    Full Text Available Background A thorough quality analysis of radiologic performance is cumbersome. Instead, the prevalence of missed cervical hip fractures might be used as a quality indicator. Purpose To validate a computer-based quality study of cervical hip fracture radiography. Material and Methods True and false negative and positive hip trauma radiography during 6 years was assessed manually. Patients with two or more radiologic hip examinations before surgery were selected by computer analysis of the databases. The first of two preoperative examinations might constitute a missed fracture. These cases were reviewed. Results Out of 1621 cervical hip fractures, manual perusal found 51 (3.1% false negative radiographic diagnoses. Among approximately 14,000 radiographic hip examinations, there were 27 (0.2% false positive diagnoses. Fifty-seven percent of false negative reports were occult fractures, the other diagnostic mistakes. There were no significant differences over the years. Diagnostic sensitivity was 96.9% and specificity 99.8%. Computer-assisted analysis with a time interval of at least 120 days between the first and the second radiographic examination discovered 39 of the 51 false negative reports. Conclusion Cervical hip trauma radiography has high sensitivity and specificity. With computer-assisted analysis, 76% of false negative reports were found.

    2014-07-01

    To evaluate the effects of therapeutic exercise on pain, stiffness, quality of life, physical function, disease activity, health-related fitness and cardiovascular risk factors in adults with spondyloarthritis (SpA). Electronic databases (Cochrane Central Register of Controlled Trials, EMBASE, MEDLINE/PubMed, PEDro, AMED, CINAHL) were systematically searched from inception to October 2013 using medical subject headings and keywords. This was supplemented by searching conference abstracts and a hand search of reference lists of included studies. Randomised and quasi-randomised studies of adults with SpA in which at least one of the comparison groups received an exercise intervention were included. Outcomes of interest were pain, stiffness, quality of life, physical function and disease activity. Secondary outcomes were health-related fitness and cardiovascular risk factors. Two reviewers independently screened studies for inclusion. Methodological quality was assessed by two reviewers using the Cochrane risk of bias tool and the PEDro scale. Twenty-four studies, involving 1,498 participants, were included. Meta-analyses were not undertaken due to clinical heterogeneity, and this review focuses on qualitative synthesis. Moderate evidence supports exercise interventions in improving physical function, disease activity and chest expansion compared to controls; there is low-level evidence of improved pain, stiffness, spinal mobility and cardiorespiratory function. Supervised group exercise yields better outcomes than unsupervised home exercise. The addition of aerobic components to flexibility programmes improves cardiorespiratory outcomes, but not cardiovascular risk factors. The most effective exercise protocol remains unclear. Current evidence suggests that therapeutic exercises are beneficial for adults with ankylosing spondylitis; effects on other SpA subtypes are unknown.

    2012-08-01

    To describe Pilates exercise according to peer-reviewed literature, and compare definitions used in papers with healthy participants and those with low back pain. A systematic review of literature was conducted. A search for "pilates" within the maximal date ranges of the Cochrane Library, Medline, Cumulative Index to Nursing and Allied Health Literature, Physiotherapy Evidence Database, ProQuest: Nursing and Allied Health Source, Proquest: Medical and Health Complete, Scopus, Sport Discus, and Web of Science, was undertaken. To be included, papers needed to describe Pilates exercise, and be published in English within an academic, peer-reviewed journal. There were no restrictions on the methodological design or quality of papers. Content analysis was used to record qualitative definitions of Pilates. Frequencies were calculated for mention of content categories, equipment, and traditional Pilates principles. Frequencies were then compared statistically in papers with healthy participants and those with low back pain. 119 papers fulfilled inclusion criteria. Findings suggest that Pilates is a mind-body exercise that focuses on strength, core stability, flexibility, muscle control, posture and breathing. Exercises can be mat-based or involve use of specialised equipment. Posture was discussed statistically significantly more often in papers with participants with low back pain compared to papers with healthy participants. Traditional Pilates principles of centering, concentration, control, precision, flow, and breathing were discussed on average in 23% of papers. Apart from breathing, these principles were not mentioned in papers with low back pain participants. There is a general consensus in the literature of the definition of Pilates exercise. A greater emphasis may be placed on posture in people with low back pain, whilst traditional principles, apart from breathing, may be less relevant. Copyright © 2012 Elsevier Ltd.

    Maria Regina Torloni

    Full Text Available BACKGROUND: Rising cesarean section (CS rates are a major public health concern and cause worldwide debates. To propose and implement effective measures to reduce or increase CS rates where necessary requires an appropriate classification. Despite several existing CS classifications, there has not yet been a systematic review of these. This study aimed to 1 identify the main CS classifications used worldwide, 2 analyze advantages and deficiencies of each system. METHODS AND FINDINGS: Three electronic databases were searched for classifications published 1968-2008. Two reviewers independently assessed classifications using a form created based on items rated as important by international experts. Seven domains (ease, clarity, mutually exclusive categories, totally inclusive classification, prospective identification of categories, reproducibility, implementability were assessed and graded. Classifications were tested in 12 hypothetical clinical case-scenarios. From a total of 2948 citations, 60 were selected for full-text evaluation and 27 classifications identified. Indications classifications present important limitations and their overall score ranged from 2-9 (maximum grade =14. Degree of urgency classifications also had several drawbacks (overall scores 6-9. Woman-based classifications performed best (scores 5-14. Other types of classifications require data not routinely collected and may not be relevant in all settings (scores 3-8. CONCLUSIONS: This review and critical appraisal of CS classifications is a methodologically sound contribution to establish the basis for the appropriate monitoring and rational use of CS. Results suggest that women-based classifications in general, and Robson's classification, in particular, would be in the best position to fulfill current international and local needs and that efforts to develop an internationally applicable CS classification would be most appropriately placed in building upon this

    Introduction Inflammatory papillary hyperplasia (IPH) is a benign lesion of the palatal mucosa. It is usually found in denture-wearers but also has been reported in patients without a history of use of a maxillary prosthesis use. Objetives The aim of this study is to review the literature to assess the prevalence of denture stomatitis and inflammatory papillary hyperplasia and the etiological factors associated. Material and Methods A search was carried out in PubMed (January 2005 to October 2015) with the key words “inflammatory papillary hyperplasia”, “denture stomatitis”, “granular stomatitis” and “Newton’s type III” The inclusion criteria were studies including at least a sample of 50 apparently healthy patients, articles published from 2005 to 2015 written in English. The exclusion criteria were reviews and non-human studies. Results Out of the 190 studies obtained initially from the search 16 articles were selected to be included in our systematic review. The prevalence of denture stomatitis was 29.56% and 4.44% for IPH. We found 5 cases of denture stomatitis among non-denture-wearer individuals. All IPH cases were associated with the use of prosthesis. Smoking and continued use of ill-fitting dentures turned out to be the most frequent risk factors for developing IPH. Conclusions IPH is a rare oral lesion and its pathogenesis still remains unclear. Its presentation among non-denture-wearers is extremely unusual. Key words:Inflammatory papillary hyperplasia, denture stomatitis, prevalence, granular stomatitis, Newton’s type III stomatitis. PMID:27918740

    In the last couple of years dynamic fixation for syndesmosis injuries, using a suture-button technique, raised more interest due to its advantages over the static fixation. In the current systematic review suture-button fixation is compared to the traditionally applied static fixation in unstable ankle fractures accompanied with distal tibiofibular syndesmosis injury, including the functional outcome, post-operative complications, reoperation rate, recurrent diastasis and financial aspects. A computerized literature search using PubMed/MEDLINE and EMBASE was conducted in search of suitable articles between January 2006 and February 2016. A total of 4 suture-button studies, 5 suture-button vs. static fixation studies and 1 study discussing the financial aspects were identified. The AOFAS of 104 patients treated with the suture-button device was 91.08 points with an average study-follow up of 24.85 months. The AOFAS of 106 patients treated with a static fixation device was 87.95 with an average follow-up of 24.78 months. Removal of the suture-button device was reported in 10.5% of 229 patients and removal of the screws in 38.5%. Dynamic fixation demonstrated to be a viable alternative to the static fixation device, with lower reoperation rates and less complications. They can accurately stabilize the ruptured syndesmosis without device breakage or loss of reduction. 1A economic/decision. Copyright © 2016 Elsevier Ltd. All rights reserved.

    2011-09-01

    Amputation of a limb may have a negative impact on the psychological and physical well-being, mobility and social life of individuals with limb amputations. Participation in sports and/or regular physical activity has a positive effect on the above mentioned areas in able-bodied individuals. Data concerning participation in sports or regular physical activity together with its benefits and risks for individuals with limb amputations are scarce. No systematic review exists that addresses a wide range of outcomes such as biomechanics, cardiopulmonary function, psychology, sport participation and sport injuries. Therefore, the aim of this article is to systematically review the literature about individuals with limb amputations and sport participation. MEDLINE (PubMed), EMBASE, CINAHL® and SportDiscus® were searched without time or language restrictions using free text words and MeSH terms. The last search date was 31 March 2010. Books, internet sites and references of included papers were checked for papers relevant to the topic under review. Papers were included if the research topic concerned sports and a minimum of ten individuals with limb amputations were part of the study population. Papers were excluded if they included individuals with amputations of body parts other than upper or lower limbs or more distal than the wrist or ankle, or if they consisted of case reports, narrative reviews, books, notes or letters to the editor. Title, abstract and full-text assessments were performed by two independent observers following a list of preset criteria. Of the 3689 papers originally identified, 47 were included in the review. Most of the included studies were older than 10 years and had cross-sectional designs. Study participants were generally younger and often had more traumatic amputations than the general population of individuals with limb amputations. Heterogeneity in population characteristics, intervention types and main outcomes made data pooling

    2015-09-01

    Full Text Available This article aims to review various modes of fracture toughness of resin composites. Also, this study intends to review the papers on the fracture mode, namely “fractography”, under scanning electron microscopy finding fracture initiation site, and the effect of filler content on the fracture toughness of resin composites. It will also review the effect of aging on the fracture toughness of resin composites in different media, mainly distilled water, and acidic environment. In the review performed on fracture toughness of resin composites we used “fracture toughness (KIc”, aging AND fracture toughness, AND fractography” of resin composites as the search strategy. The outcome of the review revealed that most of the studies investigated fracture toughness of resin composites under Mode I and less under mode II. However, some others looked at the fracture toughness of dental resin composites under mixed-mode loading conditions. It was also found that fracture toughness studies performed on the same types of resin composites resulted in different values of KIc. The differences were related to the method of performance that requires different specimen geometries.

    The purpose of this review was to evaluate the efficacy and safety of qigong for hypertension.A systematic literature search was performed in 7 databases from their respective inceptions until April 2014, including the Cochrane Library, EMBASE, PubMed, Chinese Scientific Journal Database, Chinese Biomedical Literature Database, Wanfang database, and Chinese National Knowledge Infrastructure. Randomized controlled trials of qigong as either monotherapy or adjunctive therapy with antihypertensive drugs versus no intervention, exercise, or antihypertensive drugs for hypertension were identified. The risk of bias was assessed using the tool described in Cochrane Handbook for Systematic Review of Interventions, version 5.1.0.Twenty trials containing 2349 hypertensive patients were included in the meta-analysis. The risk of bias was generally high. Compared with no intervention, qigong significantly reduced systolic blood pressure (SBP) (weighted mean difference [WMD] = -17.40 mm Hg, 95% confidence interval [CI] -21.06 to -13.74, P Qigong was inferior to exercise in decreasing SBP (WMD = 6.51 mm Hg, 95% CI 2.81 to 10.21, P = 0.0006), but no significant difference between the effects of qigong and exercise on DBP (WMD = 0.67 mm Hg, 95% CI -1.39 to 2.73, P = 0.52) was identified. Compared with antihypertensive drugs, qigong produced a clinically meaningful but not statistically significant reduction in SBP (WMD = -7.91 mm Hg, 95% CI -16.81 to 1.00, P = 0.08), but appeared to be more effective in lowering DBP (WMD = -6.08 mm Hg, 95% CI -9.58 to -2.58, P = 0.0007). Qigong plus antihypertensive drugs significantly lowered both SBP (WMD = -11.99 mm Hg, 95% CI -15.59 to -8.39, P qigong is an effective therapy for hypertension. However, more rigorously designed randomized controlled trials with long-term follow-up focusing on hard clinical outcomes are required to confirm the results.

  14. Skip segment Hirschsprung's disease: a systematic review.

    LENUS (Irish Health Repository)

    O'Donnell, Anne-Marie

    2012-02-01

    PURPOSE: Hirschsprung\\'s disease is characterised by the congenital absence of ganglion cells beginning in the distal rectum and extending proximally for varying distances. \\'Zonal aganglionosis\\' is a phenomenon involving a zone of aganglionosis occurring within normally innervated intestine. \\'Skip segment\\' Hirschsprung\\'s disease (SSHD) involves a \\'skip area\\' of normally ganglionated intestine, surrounded proximally and distally by aganglionosis. While Hirschsprung\\'s disease is believed to be the result of incomplete craniocaudal migration of neural crest-derived cells, the occurrence of SSHD has no clear embryological explanation. The aim of this study was to perform a systematic review of SSHD, reported in the literature between 1954 and 2009, in order to determine the clinical characteristics of this rare entity and its significance. METHODS: The first reported case of SSHD was published in 1954. A systematic review of SSHD cases in the literature, from 1954 to 2009, was carried out using the electronic database \\'Pubmed\\'. Detailed information was recorded regarding the age, gender, presenting symptoms and location of the skip segment in each patient. RESULTS: 24 cases of SSHD have been reported in the literature to date. 18\\/24 (75%) of these cases were males and 6\\/24 (25%) were females. Of these, 22\\/24 (92%) were cases of total colonic aganglionosis (TCA), and 2\\/24 (8%) were rectosigmoid Hirschsprung\\'s disease. Of the 22 TCA cases, 9 (41%) had a skip segment in the transverse colon, 6 (27%) in the ascending colon, 2 (9%) in the caecum and 5 (23%) had multiple skip segments. In both rectosigmoid Hirschsprung\\'s disease cases, the skip segment was in the sigmoid colon. Overall, the length of the skip segment was variable, with the entire transverse colon ganglionated in some cases. CONCLUSION: SSHD occurs predominantly in patients with TCA. The existence of a skip area of normally innervated colon in TCA may influence surgical

  15. Cost of epilepsy: a systematic review.

    2008-01-01

    The objective of this review was to overview published cost-of-illness (COI) studies of epilepsy and their methodological approaches. Epilepsy imposes a substantial burden on individuals and society as a whole. The mean prevalence of epilepsy is estimated at 0.52% in Europe, 0.68% in the US, and peaks up to 1.5% in developing countries. Estimation of the economic burden of epilepsy is of pivotal relevance to enable a rational distribution of healthcare resources. This is especially so with the introduction of the newer antiepileptic drugs (AEDs), the marketing of vagal-nerve stimulators and the resurgence of new surgical treatment options, which have the potential to considerably increase the costs of treating epilepsy.A systematic literature review was performed to identify studies that evaluated direct and indirect costs of epilepsy. Using a standardized assessment form, information on the study design, methodological framework and data sources were extracted from each publication and systematically reported. We identified 22 studies worldwide on costs of epilepsy. The majority of the studies reflected the costs of epilepsy in Europe (three studies each for the UK and Italy, one study each for Germany, the Netherlands, Switzerland, France and the EU) and the US (four studies), but studies were also available from India (two), Hong Kong, Oman, Burundi, Chile and Mexico. The studies utilized different frameworks to evaluate costs. All used a bottom-up approach; however, only 12 studies (55%) evaluated direct as well as indirect costs. The range for the mean annual direct costs lay between 40 International Dollar purchasing power parities (PPP-$) in rural Burundi and PPP-$4748 (adjusted to 2006 values) in a German epilepsy centre. Recent studies suggest AEDs are becoming the main contributor to direct costs. The mean indirect costs ranged between 12% and 85% of the total annual costs. Epilepsy is a cost-intensive disorder.

    OBJECTIVE: The objective of this paper is to describe the problem of multiple comparisons in systematic reviews and to provide some guidelines on how to deal with it in practice. STUDY DESIGN AND SETTING: We describe common reasons for multiplicity in systematic reviews, and present some examples....... We provide guidance on how to deal with multiplicity when it is unavoidable. RESULTS: We identified six common reasons for multiplicity in systematic reviews: multiple outcomes, multiple groups, multiple time points, multiple effect measures, subgroup analyses, and multiple looks at accumulating data....... The existing methods to deal with multiplicity in single trials can not always be applied in systematic reviews. CONCLUSION: There is no simple and completely satisfactory solution to the problem of multiple comparisons in systematic reviews. More research is required to develop multiple comparison procedures...

    Data abstraction is a key step in conducting systematic reviews because data collected from study reports form the basis of appropriate conclusions. Recent methodological standards and expectations highlight several principles for data collection. To support implementation of these standards, this article provides a step-by-step tutorial for selecting data collection tools; constructing data collection forms; and abstracting, managing, and archiving data for systematic reviews. Examples are drawn from recent experience using the Systematic Review Data Repository for data collection and management. If it is done well, data collection for systematic reviews only needs to be done by 1 team and placed into a publicly accessible database for future use. Technological innovations, such as the Systematic Review Data Repository, will contribute to finding trustworthy answers for many health and health care questions.

    Full Text Available In countries with low tuberculosis (TB incidence, immigrants from higher incidence countries represent the major pool of individuals with latent TB infection (LTBI. The antenatal period represents an opportunity for immigrant women to access the medical system, and hence for potential screening and treatment of LTBI. However, such screening and treatment during pregnancy remains controversial.In order to further understand the prevalence, natural history, screening and management of LTBI in pregnancy, we conducted a systematic literature review addressing the screening and treatment of LTBI, in pregnant women without known HIV infection.A systematic review of 4 databases (Embase, Embase Classic, Medline, Cochrane Library covering articles published from January 1st 1980 to April 30th 2014.

    High volume hydraulic fracturing (HVHF) of shale to stimulate the release of natural gas produces a large quantity of wastewater in the form of flowback fluids and produced water. These wastewaters are highly variable in their composition and contain a mixture of fracturing fluid additives, geogenic inorganic and organic substances, and transformation products. The qualitative and quantitative analyses of organic compounds identified in HVHF fluids, flowback fluids, and produced waters are reviewed here to communicate knowledge gaps that exist in the composition of HVHF wastewaters. In general, analyses of organic compounds have focused on those amenable to gas chromatography, focusing on volatile and semi-volatile oil and gas compounds. Studies of more polar and non-volatile organic compounds have been limited by a lack of knowledge of what compounds may be present as well as quantitative methods and standards available for analyzing these complex mixtures. Liquid chromatography paired with high-resolution mass spectrometry has been used to investigate a number of additives and will be a key tool to further research on transformation products that are increasingly solubilized through physical, chemical, and biological processes in situ and during environmental contamination events. Diverse treatments have been tested and applied to HVHF wastewaters but limited information has been published on the quantitative removal of individual organic compounds. This review focuses on recently published information on organic compounds identified in flowback fluids and produced waters from HVHF. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available Abstract Background Systematic reviews provide clinical practice recommendations that are based on evaluation of primary evidence. When systematic reviews with the same aims have different conclusions, it is difficult to ascertain which review reported the most credible and robust findings. Methods This study examined five systematic reviews that have investigated the effectiveness of Pilates exercise in people with chronic low back pain. A four-stage process was used to interpret findings of the reviews. This process included comparison of research questions, included primary studies, and the level and quality of evidence of systematic reviews. Two independent reviewers assessed the level of evidence and the methodological quality of systematic reviews, using the National Health and Medical Research Council hierarchy of evidence, and the Revised Assessment of Multiple Systematic Reviews respectively. Any disagreements were resolved by a third researcher. Results A high level of consensus was achieved between the reviewers. Conflicting findings were reported by the five systematic reviews regarding the effectiveness of Pilates in reducing pain and disability in people with chronic low back pain. Authors of the systematic reviews included primary studies that did not match their questions in relation to treatment or population characteristics. A total of ten primary studies were identified across five systematic reviews. Only two of the primary studies were included in all of the reviews due to different inclusion criteria relating to publication date and status, definition of Pilates, and methodological quality. The level of evidence of reviews was low due to the methodological design of the primary studies. The methodological quality of reviews varied. Those which conducted a meta-analysis obtained higher scores. Conclusion There is inconclusive evidence that Pilates is effective in reducing pain and disability in people with chronic low back

    Full Text Available BACKGROUND: Systematic reviews (SRs should be up to date to maintain their importance in informing healthcare policy and practice. However, little guidance is available about when and how to update SRs. Moreover, the updating policies and practices of organizations that commission or produce SRs are unclear. METHODOLOGY/PRINCIPAL FINDINGS: The objective was to describe the updating practices and policies of agencies that sponsor or conduct SRs. An Internet-based survey was administered to a purposive non-random sample of 195 healthcare organizations within the international SR community. Survey results were analyzed using descriptive statistics. The completed response rate was 58% (n = 114 from across 26 countries with 70% (75/107 of participants identified as producers of SRs. Among responders, 79% (84/107 characterized the importance of updating as high or very-high and 57% (60/106 of organizations reported to have a formal policy for updating. However, only 29% (35/106 of organizations made reference to a written policy document. Several groups (62/105; 59% reported updating practices as irregular, and over half (53/103 of organizational respondents estimated that more than 50% of their respective SRs were likely out of date. Authors of the original SR (42/106; 40% were most often deemed responsible for ensuring SRs were current. Barriers to updating included resource constraints, reviewer motivation, lack of academic credit, and limited publishing formats. Most respondents (70/100; 70% indicated that they supported centralization of updating efforts across institutions or agencies. Furthermore, 84% (83/99 of respondents indicated they favoured the development of a central registry of SRs, analogous to efforts within the clinical trials community. CONCLUSIONS/SIGNIFICANCE: Most organizations that sponsor and/or carry out SRs consider updating important. Despite this recognition, updating practices are not regular, and many organizations lack

    Full Text Available Background: Injuries are the second greatest cause of mortality in Iran. Information about the epidemiological pattern of injuries is effective in decision-making. In this regard, the aim of the current study is to elaborate on the epidemiology of injuries in Iran through a systematic review. Methods: Required data were collected searching the following key words and their Persian equivalents; trauma, injury, accident, epidemiology, prevalence, Pattern, etiology, risk factors and Iran. The following databases were searched: Google Scholar, PubMed, Scopus, MagIran, Iranian scientific information database (SID and Iran Medex. Some of the relevant journals and web sites were searched manually. The lists of references from the selected articles were also investigated. We have also searched the gray literature and consulted some experts. Results: Out of 2747 retrieved articles, 25 articles were finally included in the review. A total of 3234481 cases have been investigated. Mean (SD age among these cases was 30 (17.4 years. Males comprised 75.7% of all the patients. Only 31.1% of patients were transferred to hospital by ambulance. The most common mechanism of injuries was road traffic accidents (50.1%, followed by falls (22.3%. In road traffic accidents, motorcyclists have accounted for the majority of victims (45%. Roads were the most common accident scene for the injuries (57.5%. The most common injuries were to the head and neck. (47.3%. The mean (SD Injury Severity Score (ISS was 8.1(8.6%. The overall case-fatality proportion was 3.8% and 75% of all the mortalities related to road traffic accidents. Conclusions: The main priorities in reducing the burden of injuries include: the young, male target group, improving pre-hospital and ambulance services, preventing road traffic accidents, improving road safety and the safety of motorcyclists (compulsory helmet use, safer vehicles, dedicated motorcycle lanes.

    Dietary patterns analysis is an emerging area of research. Identifying distinct patterns within a large dietary survey can give a more accurate representation of what people are eating. Furthermore, it allows researchers to analyse relationships between non-communicable diseases (NCD) and complete diets rather than individual food items or nutrients. However, few such studies have been conducted in developing countries including India, where the population has a high burden of diabetes and CVD. We undertook a systematic review of published and grey literature exploring dietary patterns and relationships with diet-related NCD in India. We identified eight studies, including eleven separate models of dietary patterns. Most dietary patterns were vegetarian with a predominance of fruit, vegetables and pulses, as well as cereals; dietary patterns based on high-fat, high-sugar foods and more meat were also identified. There was large variability between regions in dietary patterns, and there was some evidence of change in diets over time, although no evidence of different diets by sex or age was found. Consumers of high-fat dietary patterns were more likely to have greater BMI, and a dietary pattern high in sweets and snacks was associated with greater risk of diabetes compared with a traditional diet high in rice and pulses, but other relationships with NCD risk factors were less clear. This review shows that dietary pattern analyses can be highly valuable in assessing variability in national diets and diet-disease relationships. However, to date, most studies in India are limited by data and methodological shortcomings.

    This article describes a novel approach for using EndNote to manage and code references in the conduct and reporting of systematic reviews and scoping reviews. The process is simple and easy for reviewers new to both EndNote and systematic reviews. This process allows reviewers to easily conduct and report systematic reviews in line with the internationally recognized PRISMA reporting guidelines and also facilitates the overall task of systematic or scoping review conduct and reporting from the initial search through to structuring the results, discussion, and conclusions in a rigorous, reproducible, and user-friendly manner.

    The objective of this research study was to conduct a systematic review of the research on volunteers using Clary et al.’s VFI (1998). A total of 48 research studies including 67 independent samples met eligibility criteria. The total sample of the studies analyzed ranged from 20375 to 21988 participants, depending on the motivation analyzed. The results show that the Values factor obtained the highest mean score, both overall and in each type of volunteering, whereas the lowest scores were for the Career and Enhancement factors. Studies conducted with samples with a mean age under 40 years obtain higher scores on Career and Understanding scales when compared to studies in older samples. The group of studies with less than 50% women yield higher mean scores on the Social scale than studies with more than 50% women in the sample. All the scales show reliability coefficients between .78 and .84. Only eight of the articles provide data on the reliability of the scale with a mean value of .90. Of the 26 studies that performed factor analysis, 18 confirmed the original structure of six factors.

    Growing evidence has suggested the utility of short dental implants for oral reconstructive procedures in clinical situations of limited vertical bone height. The aim of this review was to systematically evaluate clinical studies of implants type of edentulism, and prosthetic restoration. Two randomized controlled trials and 14 observational studies were selected and analyzed for data extraction. In total, 6193 short-implants were investigated from 3848 participants. The observational period was 3.2 ± 1.7 yrs (mean ± SD). The cumulative survival rate (CSR) was 99.1% (95%CI: 98.8-99.4). The biological success rate was 98.8% (95%CI: 97.8-99.8), and the biomechanical success rate was 99.9% (95%CI: 99.4-100.0). A higher CSR was reported for rough-surfaced implants. The provision of short implant-supported prostheses in patients with atrophic alveolar ridges appears to be a successful treatment option in the short term; however, more scientific evidence is needed for the long term.

    The aim of this paper was to systematically review the literature on coping in sport, examining evidence for both the trait and process perspectives, the types of coping strategies used by athletes, gender differences, age-related differences, and coping effectiveness. A comprehensive literature search of SPORTdiscus, PsychLIT, and PsychINFO in November 2004 yielded 64 studies spanning 16 years (1988 - 2004). The results indicated that athletes use a variety of coping strategies. Forty-six papers supported or adopted the process perspective (Lazarus, 1999; Lazarus & Folkman, 1984). There were also gender and age-related differences. Evidence was found to support three of the different models of coping effectiveness (goodness-of-fit approach, choice of coping strategy, and automacity). Based on this evidence, future research should address some of the methodological and measurement limitations of the sport psychology coping literature. In particular, prospective research designs that minimize the time delay between recall and the stressful experience are required to assess how coping changes over time. More attention to developmental issues to guide the formulation of sport-specific models to enhance our theoretical understanding is also required. Finally, coping effectiveness should be examined both in the short and long term, as a greater understanding of coping effectiveness has the potential to make a significant impact on applied practice.

    Social robotics could be a promising method for Autism Spectrum Disorders (ASD) treatment. The aim of this article is to carry out a systematic literature review of the studies on this topic that were published in the last 10 years. We tried to address the following questions: can social robots be a useful tool in autism therapy? We followed the PRISMA guidelines, and the protocol was registered within PROSPERO database (CRD42015016158). We found many positive implications in the use of social robots in therapy as for example: ASD subjects often performed better with a robot partner rather than a human partner; sometimes, ASD patients had, toward robots, behaviors that TD patients had toward human agents; ASDs had a lot of social behaviors toward robots; during robotic sessions, ASDs showed reduced repetitive and stereotyped behaviors and, social robots manage to improve spontaneous language during therapy sessions. Therefore, robots provide therapists and researchers a means to connect with autistic subjects in an easier way, but studies in this area are still insufficient. It is necessary to clarify whether sex, intelligence quotient, and age of participants affect the outcome of therapy and whether any beneficial effects only occur during the robotic session or if they are still observable outside the clinical/experimental context.

    Intimate partner violence (IPV) is a global public health and criminal justice concern with significant impacts; especially high rates are seen among rural Hispanic American (HA) communities, the fastest growing population in the United States. They experience additional barriers to care including extreme poverty, lesser education, gender norms, and language and immigration issues. A systematic literature review was conducted using Cooper's framework to identify evidence supporting associations between interventions and prevention, reduction, and elimination of IPV among rural HA women. Searches conducted on databases including CINAHL, PubMed, Medline, Women's Studies International, MedicLatina, and JSTOR used the MeSH terms Hispanic Americans (Latino/a and Hispanic), domestic violence, and intimate partner violence. Selected studies were published between January 1, 2000, and January 1, 2014. Of the 617 yielded articles, only 6 met the inclusion criteria. Of these, none closely examined rurality or provided valid and reliable measures of outcomes, instead reporting program descriptions and suggested interventions. We identify key findings to guide program, screening, and tool development. Our study identifies a gap in knowledge, research, and effective practices and issues a call for action to create evidence-based tools to prevent, reduce, and eliminate IPV in these underserved populations.

    Proprioception is a vital aspect of motor control and when degraded or lost can have a profound impact on function in diverse clinical populations. This systematic review aimed to identify clinically related tools to measure proprioceptive acuity, to classify the construct(s) underpinning the tools, and to report on the clinimetric properties of the tools. We searched key databases with the pertinent search terms, and from an initial list of 935 articles, we identified 57 of relevance. These articles described 32 different tools or methods to quantify proprioception. There was wide variation in methods, the joints able to be tested, and the populations sampled. The predominant construct was active or passive joint position detection, followed by passive motion detection and motion direction discrimination. The clinimetric properties were mostly poorly evaluated or reported. The Rivermead Assessment of Somatosensory Perception was generally considered to be a valid and reliable tool but with low precision; other tools with higher precision are potentially not clinically feasible. Clinicians and clinical researchers can use the summary tables to make more informed decisions about which tool to use to match their predominant requirements. Further discussion and research is needed to produce measures of proprioception that have improved validity and utility.

    Full Text Available Through the method of Systematic Review of Literature (SRL, this study conducted an analysis of productivity in services. For this purpose, fourteen journals of Operations Management and Scielo database were consulted. The studies were analyzed with respect to six criteria for classification: i type of study, ii investigated business sector, iii affiliation of authors, iv prevailing methodological approach, v themes, e vi methods used in comparative analyzes of performance. It was found that the greatest amount of work used the modeling approach to assess the productivity, particularly by linear programming methodology - Data Analysis Envelopment (DEA. It was observed that the vast majority of authors are academic, there are few publications of researchers from companies or that have both types of researchers. The study identified four recurring themes in the articles. Then, some studies have focused on the establishment of productivity indicators and their analysis over time, comparing the performance of different firms or industries. Other studies have identified the characteristics and difficulties of measuring productivity in services in relation to manufacturing companies. Different studies have proposed indicators to measure productivity in services. Finally, in light of the main textbooks on operation's management and service literature, this study identified key strategies and methods for improving productivity in services. It was found that the theme productivity in services is a promising research topic.

    Vitamin D has been well-known for its function in maintaining calcium and phosphorus homeostasis and promoting bone mineralization. There is some evidence that in addition to sex steroid hormones, the classic regulators of human reproduction, vitamin D also modulates reproductive processes in women and men. The aim of this review was to assess the studies that evaluated the relationship between vitamin D and fertility in women and men as well as in animals. We performed a systematic literature search in Pubmed for relevant English language publications published until October 2011. The vitamin D receptor (VDR) and vitamin D metabolizing enzymes are found in reproductive tissues of women and men. Vdr knockout mice have significant gonadal insufficiency, decreased sperm count and motility, and histological abnormalities of testis, ovary and uterus. Moreover, we present evidence that vitamin D is involved in female reproduction including IVF outcome (clinical pregnancy rates) and polycystic ovary syndrome (PCOS). In PCOS women, low 25-hydroxyvitamin D (25(OH)D) levels are associated with obesity, metabolic, and endocrine disturbances and vitamin D supplementation might improve menstrual frequency and metabolic disturbances in those women. Moreover, vitamin D might influence steroidogenesis of sex hormones (estradiol and progesterone) in healthy women and high 25(OH)D levels might be associated with endometriosis. In men, vitamin D is positively associated with semen quality and androgen status. Moreover, vitamin D treatment might increase testosterone levels. Testiculopathic men show low CYP21R expression, low 25(OH)D levels, and osteoporosis despite normal testosterone levels.

    The aim of this systematic review is to identify published randomized controlled trials (RCTs) that evaluated the use of oxytocin in individuals with frontotemporal dementia (FTD). A literature search was conducted of PubMed, MEDLINE, EMBASE, PsycINFO and Cochrane collaboration databases for RCTs in any language that evaluated the use of oxytocin in individuals with FTD. Bibliographic databases of published articles were also searched for additional studies. A total of two RCTs that evaluated the use of oxytocin in individuals with FTD were identified. In one study, the use of oxytocin in individuals with FTD produced a reduction in identification of negative facial expressions (anger and fear) which can be hypothesized to improve trust and increase cooperation in these individuals. Both studies noted oxytocin was well tolerated and showed short term benefits on behavioral symptoms in individuals with FTD. Oxytocin appears to improve social aspects of cognition and behavioral symptoms in individuals with FTD and is well tolerated. However, positive data from larger and longer duration RCTs are needed before the routine use of oxytocin in individuals with FTD can be recommended.

    Full Text Available OBJECTIVE: A systematic review on nickel-titanium wires was performed. The strategy was focused on Entrez-PubMed-OLDMEDLINE, Scopus and BioMed Central from 1963 to 2008. METHODS: Papers in English and French describing the behavior of these wires and laboratorial methods to identify crystalline transformation were considered. A total of 29 papers were selected. RESULTS: Nickel-titanium wires show exceptional features in terms of elasticity and shape memory effects. However, clinical applications request a deeper knowledge of these properties in order to allow the professional to use them in a rational manner. In addition, the necessary information regarding each alloy often does not correspond to the information given by the manufacturer. Many alloys called "superelastic" do not present this effect; they just behave as less stiff alloys, with a larger springback if compared to the stainless steel wires. CONCLUSIONS: Laboratory tests are the only means to observe the real behavior of these materials, including temperature transition range (TTR and applied tensions. However, it is also possible to determine in which TTR these alloys change the crystalline structure.

    Full Text Available This paper is an attempt to consolidate the published scientific knowledge about the impact of leadership styles on the relationship between innovation and organisational performance. Concepts, statements and conceptual frameworks were used as structure to analyse the body of scientific knowledge. After consulting 31 major research databases using the systematic literature review methodology, only seven journals articles that examined the link between leadership, innovation and organisational performance were identified. The synthesis of the journal articles revealed (a that consensus exists among researchers as far as the relevant concepts are concerned; (b that most agree on the definition of leadership and innovation but that a uniform understanding of what constitutes organisational performance is lacking; and (c that conceptual models are too simplistic and do not consider mediator variables or multiple financial criteria measures. The findings further reveal that innovation is significantly and positively related to superior organisational performance, and that, although transformational leadership style is significantly and positively related to innovation, transactional leadership style is more appropriate when the aim is to instil a culture of innovation. Transformational leadership style, by contrast, is mostly associated with organisational performance. In addition, the findings further reveal that none of the studies investigate the mediating effect of the nature of innovation (incremental and radical on the relationship between leadership and organisational performance, and that none of the studies use the objective measures of financial performance such as ROA, ROE, price/earnings (P/E and Tobin’s Q calculated from annual financial reports.

    Cyberbullying is a new form of violence that is expressed through electronic media and has given rise to concern for parents, educators and researchers. In this paper, an association between cyberbullying and adolescent mental health will be assessed through a systematic review of two databases: PubMed and Virtual Health Library (BVS). The prevalence of cyberbullying ranged from 6.5% to 35.4%. Previous or current experiences of traditional bullying were associated with victims and perpetrators of cyberbullying. Daily use of three or more hours of Internet, web camera, text messages, posting personal information and harassing others online were associated with cyberbullying. Cybervictims and cyberbullies had more emotional and psychosomatic problems, social difficulties and did not feel safe and cared for in school. Cyberbullying was associated with moderate to severe depressive symptoms, substance use, ideation and suicide attempts. Health professionals should be aware of the violent nature of interactions occurring in the virtual environment and its harm to the mental health of adolescents.

    Early identification of children at risk of developing asthma at school age is crucial, but the usefulness of childhood asthma prediction models in clinical practice is still unclear. We systematically reviewed all existing prediction models to identify preschool children with asthma-like symptoms at risk of developing asthma at school age. Studies were included if they developed a new prediction model or updated an existing model in children aged 4 years or younger with asthma-like symptoms, with assessment of asthma done between 6 and 12 years of age. 12 prediction models were identified in four types of cohorts of preschool children: those with health-care visits, those with parent-reported symptoms, those at high risk of asthma, or children in the general population. Four basic models included non-invasive, easy-to-obtain predictors only, notably family history, allergic disease comorbidities or precursors of asthma, and severity of early symptoms. Eight extended models included additional clinical tests, mostly specific IgE determination. Some models could better predict asthma development and other models could better rule out asthma development, but the predictive performance of no single model stood out in both aspects simultaneously. This finding suggests that there is a large proportion of preschool children with wheeze for which prediction of asthma development is difficult.

    The volume of scientific literature continues to expand and decision-makers are faced with increasingly unmanageable volumes of evidence to assess. Systematic reviews (SRs) are powerful tools that aim to provide comprehensive, transparent, reproducible and updateable summaries of evidence. SR methods were developed, and have been employed, in healthcare for more than two decades, and they are now widely used across a broad range of topics, including environmental management and social interventions in crime and justice, education, international development, and social welfare. Despite these successes and the increasing acceptance of SR methods as a 'gold standard' in evidence-informed policy and practice, misconceptions still remain regarding their applicability. The aim of this article is to separate fact from fiction, addressing twelve common misconceptions that can influence the decision as to whether a SR is the most appropriate method for evidence synthesis for a given topic. Through examples, we illustrate the flexibility of SR methods and demonstrate their suitability for addressing issues on environmental health and chemical risk assessment.

    Olfactory dysfunction is a key symptom in patients with allergic rhinitis (AR). Despite the implications for quality of life, relatively few articles have tested olfactory function in their investigations. The current systematic review aimed to investigate the following 2 questions: (1) What does AR do to human olfaction? (2) How effective is the treatment of AR in restoring the sense of smell? A comprehensive literature search was performed, and human studies of any design were included. A total of 420 articles were identified, and 36 articles were considered relevant. Data indicate that the frequency of olfactory dysfunction increases with the duration of the disorder, and most studies report a frequency in the range of 20% to 40%. Although olfactory dysfunction does not appear to be very severe in patients with AR, its presence seems to increase with the severity of the disease. There is very limited evidence that antihistamines improve olfactory function. In addition, there is limited evidence that topical steroids improve the sense of smell, especially in patients with seasonal AR. This is also the case for specific immunotherapy. However, many questions remain unanswered because randomized controlled trials are infrequent and only a few studies rely on quantitative measurement of olfactory function.

    Full Text Available Cyberbullying is a new form of violence that is expressed through electronic media and has given rise to concern for parents, educators and researchers. In this paper, an association between cyberbullying and adolescent mental health will be assessed through a systematic review of two databases: PubMed and Virtual Health Library (BVS. The prevalence of cyberbullying ranged from 6.5% to 35.4%. Previous or current experiences of traditional bullying were associated with victims and perpetrators of cyberbullying. Daily use of three or more hours of Internet, web camera, text messages, posting personal information and harassing others online were associated with cyberbullying. Cybervictims and cyberbullies had more emotional and psychosomatic problems, social difficulties and did not feel safe and cared for in school. Cyberbullying was associated with moderate to severe depressive symptoms, substance use, ideation and suicide attempts. Health professionals should be aware of the violent nature of interactions occurring in the virtual environment and its harm to the mental health of adolescents.

    Pregnancy is a period of increased vulnerability for migrant women, and access to healthcare, use and quality of care provided during this period are important aspects to characterize the support provided to this population. A systematic review of the scientific literature contained in the MEDLINE and SCOPUS databases was carried out, searching for population based studies published between 1990 and 2012 and reporting on maternal healthcare in immigrant populations. A total of 854 articles were retrieved and 30 publications met the inclusion criteria, being included in the final evaluation. The majority of studies point to a higher health risk profile in immigrants, with an increased incidence of co-morbidity in some populations, reduced access to health facilities particularly in illegal immigrants, poor communication between women and caregivers, a lower rate of obstetrical interventions, a higher incidence of stillbirth and early neonatal death, an increased risk of maternal death, and a higher incidence of postpartum depression. Incidences vary widely among different population groups. Some migrant populations are at a higher risk of serious complications during pregnancy, for reasons that include reduced access and use of healthcare facilities, as well as less optimal care, resulting in a higher incidence of adverse outcomes. Tackling these problems and achieving equality of care for all is a challenging aim for public healthcare services.

    Acetabular fractures with quadrilateral plate involvement form a heterogeneous group of fractures, which are not specifically defined by any current classification system. Their incidence is increasing due to the rising number of elderly osteoporotic fractures. They have always been notoriously difficult fractures to treat. We present a systematic review of conservative and operative management and their respective outcomes over the last century.

    Management of polytrauma patients is one the most difficult and challenging tasks for an orthopaedic surgeon, and it includes different aspects of intervention: emergent resuscitative care, early surgical care, post-operative care and delayed rehabilitative care. We report an interesting case of multiple skeletal injuries with a coexisting pattern of fractures of bilateral patellae with bilateral pertrochanteric fractures of femur with a missed talar fracture following a dashboard type of injury in a road traffic accident. We are not aware of a similar case reported in literature in the past. We highlight the management protocol in such a case and review the available literature regarding such a presentation.

    Objective. As evidence of the effectiveness of acupuncture for low back pain (LBP) is inconsistent, we aimed to critically appraise the evidence from relevant systematic reviews. Methods. Systematic reviews of randomized controlled trials (RCTs) concerning acupuncture and LBP were searched in seven databases. Internal validity and external validity of systematic reviews were assessed. Systematic reviews were categorized and high quality reviews assigned greater weightings. Conclusions were generated from a narrative synthesis of the outcomes of subgroup comparisons. Results. Sixteen systematic reviews were appraised. Overall, the methodological quality was low and external validity weak. For acute LBP, evidence that acupuncture has a more favorable effect than sham acupuncture in relieving pain was inconsistent; it had a similar effect on improving function. For chronic LBP, evidence consistently demonstrated that acupuncture provides short-term clinically relevant benefits for pain relief and functional improvement compared with no treatment or acupuncture plus another conventional intervention. Conclusion. Systematic reviews of variable quality showed that acupuncture, either used in isolation or as an adjunct to conventional therapy, provides short-term improvements in pain and function for chronic LBP. More efforts are needed to improve both internal and external validity of systematic reviews and RCTs in this area.

    People with dementia are 2.7 times more likely to suffer a hip fracture than those without and their management is estimated to cost £0.92 billion per year. Yet there has been little focus on the effectiveness of interventions for this population. The aim of this scoping review was to summarise the current available evidence for physiotherapy interventions for people with dementia who fracture their hip as well as to identify gaps in the literature that may require further research. A systematic search of the following databases was undertaken-TRIP, CINAHL, Amed, Embase, PEDro, PsycINFO, Cochrane Library, Open Grey, Ethos, ISRCTN, Proquest, PROSPERO and UK Clinical Trials Gateway. Articles were included if they described an intervention which is considered within the scope of a physiotherapist and targeted those with both a hip fracture and dementia. A narrative summary was then undertaken to describe the current state of the literature. Twenty six studies were included, of which thirteen were observational, six RCTs, two qualitative, two surveys and three systematic reviews. Only nine studies focused explicitly on physiotherapy interventions. The findings of this scoping review suggest there is limited evidence to guide physiotherapists in the management of people with dementia who fracture their hip. No evidence was found about perceptions or experiences of patients in this group or of the physiotherapists involved in their care. Further research is needed to develop and evaluate physiotherapy interventions for people with dementia who fracture their hip. Copyright © 2017 Chartered Society of Physiotherapy.

    To systematically review the psychometric evidence on the 2-minute walk test (2MWT). Electronic searches of databases including MEDLINE, CINAHL, Academic Search Premier, SPORTDiscus, PsycINFO, EMBASE, the Cochrane Library, and DARE were done until February 2014 using a combination of subject headings and free texts. Studies were included if psychometric properties of the 2MWT were (1) evaluated; (2) written as full reports; and (3) published in English language peer-reviewed journals. A modified consensus-based standard for the selection of health measurement instruments checklist was used to rate the methodological quality of the included studies. A quality assessment for statistical outcomes was used to assess the measurement properties of the 2MWT. Best-evidence synthesis was collated from 25 studies of 14 patient groups. Only 1 study was found that examined the 2MWT in the pediatric population. The testing procedures of the 2MWT varied across the included studies. Reliability, validity (construct and criterion), and responsiveness of the 2MWT also varied across different patient groups. Moderate to strong evidence was found for reliability, convergent validity, discriminative validity, and responsiveness of the 2MWT in frail elderly patients. Moderate to strong evidence for reliability, convergent validity, and responsiveness was found in adults with lower limb amputations. Moderate to strong evidence for validity (convergent and discriminative) was found in adults who received rehabilitation after hip fractures or cardiac surgery. Limited evidence for the psychometric properties of the 2MWT was found in other population groups because of methodological flaws. There is inadequate breadth and depth of psychometric evidence of the 2MWT for clinical and research purposes-specifically, minimal clinically important changes and responsiveness. More good-quality studies are needed, especially in the pediatric population. Consensus on standardized testing procedures of

    Full Text Available Background: Calcium (Ca is an essential nutrient for the human body. Despite lively research, there is uncertainty about Ca requirements in terms of desirable health outcomes including an upper intake level above which the potential for harm increases. Objectives: The aim was to conduct a review to update requirements and desirable or harmful health effects of Ca on the current scientific evidence. Methods: We searched Medline and Swemed from January 2000 to December 2011 and included all systematic reviews that reported Ca supplementation or usual Ca intake on health outcomes. Meta-analyses, randomized clinical trials and cohort studies were included in the second search between May 2009 and March 2011 and an additional search covering studies till the end of 2011. This review concentrated on studies reporting independent effects of Ca, although a few recent trials report sole effects of Ca on health outcomes, most trials use Ca in combination with vitamin D vs. placebo. Results: In total, we reviewed 38 studies addressing the effects of Ca on bone, pregnancy-related outcomes, cancers, cardiovascular outcomes, obesity, and mortality. There was a lot of heterogeneity in the study protocols, which made it difficult to draw any strong conclusions. According to the literature, high Ca intake seems to have a small positive effect on bone mineral content (BMC or bone mineral density (BMD in children and postmenopausal women. We did not find any consistent evidence on the effects of Ca on bone health in premenopausal women or men. Also, the evidence that Ca supplementation reduces fracture incidence is scarce and inconsistent. Maternal diet may influence the peak bone mass of offspring but more studies are required. There was no overall effect of Ca intake on cancers. Ca was associated with a decreased risk of breast cancer and a slightly increased risk of prostate cancer in two of the three studies. No associations were found with other cancers. We

    Human milk-associated microbes are among the first to colonize the infant gut and may help to shape both short- and long-term infant health outcomes. We performed a systematic review to characterize the microbiota of human milk. Relevant primary studies were identified through a comprehensive search of PubMed (January 1, 1964, to June 31, 2015). Included studies were conducted among healthy mothers, were written in English, identified bacteria in human milk, used culture-independent methods, and reported primary results at the genus level. Twelve studies satisfied inclusion criteria. All varied in geographic location and human milk collection/storage/analytic methods. Streptococcus was identified in human milk samples in 11 studies (91.6%) and Staphylococcus in 10 (83.3%); both were predominant genera in 6 (50%). Eight of the 12 studies used conventional ribosomal RNA (rRNA) polymerase chain reaction (PCR), of which 7 (87.5%) identified Streptococcus and 6 (80%) identified Staphylococcus as present. Of these 8 studies, 2 (25%) identified Streptococcus and Staphylococcus as predominant genera. Four of the 12 studies used next-generation sequencing (NGS), all of which identified Streptococcus and Staphylococcus as present and predominant genera. Relative to conventional rRNA PCR, NGS is a more sensitive method to identify/quantify bacterial genera in human milk, suggesting the predominance of Streptococcus and Staphylococcus may be underestimated in studies using older methods. These genera, Streptococcus and Staphylococcus, may be universally predominant in human milk, regardless of differences in geographic location or analytic methods. Primary studies designed to evaluate the effect of these 2 genera on short- and long-term infant outcomes are warranted.

    Full Text Available The purpose of this study was to systematically review the Brazilian literature on the prevalence of obesity and associated factors in adolescents. The literature search was carried out in the electronic databases Pubmed and Bireme, using the keywords: obesity, overweight, BMI, adolescents and Brazil. The following inclusion criteria were considered: Brazilian adolescents, BMI-based obesity estimates, publication until 2007, and adequate methodology. After the examination of titles, abstracts and full texts, 27 papers fulfilled our inclusion criteria. For describing the studies, the following variables were used: type of survey, design, age range, sample size, place of data collection. For evaluating the evidence, the following indicators were used: methods used, independent variables studied, statistical analyses employed, and cut-off used for defining obesity. Most studies used cross-sectional designs (77.7% and were carried out through home interviews (51.7%. Only one study used a nationally-based sample and three used regional-based samples (Northeast and Southeast. Regardless the design, place, type of survey, age range and cut-off used, the prevalence of obesity tended to be higher in the following groups: adolescents living in the Southeast region, living in urban areas, from high socioeconomic level and from private schools. In terms of behavioral determinants of obesity, the paucity of prospective studies and the difficulties of adequately measuring physical activity and food consumption, make the results less clear. Although the number of studies has increased, it is still necessary to stimulate surveys in the North, Southeast and Mideast regions. Prospective studies are also necessary, in order to evaluate the association between obesity and behavioral exposures.

    2014-11-01

    The optimal management of olecranon bursitis is ill-defined. The purposes of this review were to systematically evaluate clinical outcomes for aseptic versus septic bursitis, compare surgical versus nonsurgical management, and examine the roles of corticosteroid injection and aspiration in aseptic bursitis. The English-language literature was searched using PubMed, Cumulative Index to Nursing and Allied Health Literature, Physiotherapy Evidence Database, Allied and Complementary Medicine, and Cochrane Central Register of Controlled Trials. Analyses were performed for clinical resolution and complications after treatment of aseptic and/or septic olecranon bursitis. Twenty-nine studies containing 1278 patients were included. Compared with septic bursitis, aseptic bursitis was associated with a significantly higher overall complication rate (p = 0.0108). Surgical management was less likely to clinically resolve septic or aseptic bursitis (p = 0.0476), and demonstrated higher rates of overall complications (p = 0.0117), persistent drainage (p = 0.0194), and bursal infection (p = 0.0060) than nonsurgical management. Corticosteroid injection for aseptic bursitis was associated with increased overall complications (p = 0.0458) and skin atrophy (p = 0.0261). Aspiration did not increase the risk of bursal infection for aseptic bursitis. Based primarily on level IV evidence, nonsurgical management of olecranon bursitis is significantly more effective and safer than surgical management. The clinical course of aseptic bursitis appears to be more complicated than that of septic bursitis. Corticosteroid injection is associated with significant risks without improving the outcome of aseptic bursitis. Therapeutic IV.

    Lung transplant candidates and recipients have significant impairments in skeletal muscle mass, strength and function--individual measures of sarcopenia. Skeletal muscle dysfunction has been observed in the pre-transplant and post-transplant period and could have an important effect on transplant outcomes. A systematic review was performed to characterize the techniques used to study sarcopenia and assess the level of impairment throughout the transplant process. Electronic databases were searched (inception to July 2013) for prospective studies measuring at least 1 element of sarcopenia (muscle mass, strength, or function) in lung transplant patients. Eighteen studies were included, and study quality was assessed using the Downs and Black scale. A variety of measurements were used to evaluate sarcopenia in 694 lung transplant patients. Muscle mass in 7 studies was assessed using bioelectrical impedance (n = 4), computed tomography or magnetic resonance imaging (n = 2), or skin folds (n = 1), and was significantly reduced. Quadriceps strength was examined in 14 studies with computerized dynamometer (n = 10) and hand-held dynamometer (n = 4). Quadriceps strength was reduced in the pre-transplant period (mean range, 49%-86% predicted; n = 455 patients), further reduced immediately after transplant (51%-72%, n = 126), and improved beyond 3 months after transplant (58%-101%, n = 164). Only 2 studies measured lower extremity function (sit-to-stand test). A multitude of measurement techniques have been used to assess individual measures of sarcopenia, with reduced muscle mass and quadriceps strength observed in the pre-transplant and post-transplant period. Further standardization of measurement techniques is needed to assess the clinical effect of sarcopenia in lung transplantation.

    Objective To determine the safety of ciprofloxacin in paediatric patients in relation to arthropathy, any other adverse events (AEs) and drug interactions. Methods A systematic search of MEDLINE, EMBASE, CINAHL, CENTRAL and bibliographies of relevant articles was carried out for all published articles, regardless of design, that involved the use of ciprofloxacin in any paediatric age group ≤17 years. Only articles that reported on safety were included. Results 105 articles met the inclusion criteria and involved 16 184 paediatric patients. There were 1065 reported AEs (risk 7%, 95% CI 3.2% to 14.0%). The most frequent AEs were musculoskeletal AEs, abnormal liver function tests, nausea, changes in white blood cell counts and vomiting. There were six drug interactions (with aminophylline (4) and methotrexate (2)). The only drug related death occurred in a neonate who had an anaphylactic reaction. 258 musculoskeletal events occurred in 232 paediatric patients (risk 1.6%, 95% CI 0.9% to 2.6%). Arthralgia accounted for 50% of these. The age of occurrence of arthropathy ranged from 7 months to 17 years (median 10 years). All cases of arthropathy resolved or improved with management. One prospective controlled study estimated the risk of arthropathy as 9.3 (OR 95% CI 1.2 to 195). Pooled safety data of controlled trials in this review estimated the risk of arthropathy as 1.57 (OR 95% CI 1.26 to 1.97). Conclusion Musculoskeletal AEs occur due to ciprofloxacin use. However, these musculoskeletal events are reversible with management. It is recommended that further prospective controlled studies should be carried out to evaluate the safety of ciprofloxacin, with particular focus on the risk of arthropathy. PMID:21785119

    2013-11-01

    Full Text Available Background: Jellyfishes belong to the phylum Cnidarians with a wide range of size, from 22 centimeters to 2.5 meters. Jellyfishes have a worldwide distribution comprising over nine thousands species that approximately, 100 species are dangerous for humans. The venoms of these organisms contain biomolecules with extensive activities which could be used as a source of novel drugs in the future. Materials and Methods: The PubMed data bank was searched for the term “Jellyfish”. A total of 1677 papers were found. These papers were divided into three categories: medical, biomedical and biotechnological fields. The medical category was further divided into three subcategories comprising systemic manifestations, cutaneous manifestations and treatments for the stings of jellyfishes. The biomedical category was further subdivided into genomics, proteomics, and biology of venoms, mechanisms of actions and products of biomedical significance. In this part of systematic review, the biomedical and biotechnological and biotechnological fields were evaluated. Results: The genomics and proteomics of 24 species of jellyfishes had been studied in details. The mechanisms of actions of the venoms of 23 species were under investigations. The hematologic (hemolytic effects, cardiotoxic, neurotoxic, dermonecrotic, immunologic and cytotoxic presentations for the venoms were reported. Similar clinical presentations could be produced by different species of jellyfishes with a vast of molecular action mechanisms. Bioactive molecules with cytotoxic, anticancer, antibacterial and antioxidant effects were isolated from the venoms. Conclusion: The venoms of jellyfishes have bioactive molecules that produce a variety of complex intracellular interactions. Hence, the studies on the venomics of jellyfishes and the mechanisms of actions of their venoms could progress the therapeutic interventions and promise novel marine drugs.

  1. Personal Health Records: A Systematic Literature Review

    Science.gov (United States)

    2017-01-01

    Background Information and communication technology (ICT) has transformed the health care field worldwide. One of the main drivers of this change is the electronic health record (EHR). However, there are still open issues and challenges because the EHR usually reflects the partial view of a health care provider without the ability for patients to control or interact with their data. Furthermore, with the growth of mobile and ubiquitous computing, the number of records regarding personal health is increasing exponentially. This movement has been characterized as the Internet of Things (IoT), including the widespread development of wearable computing technology and assorted types of health-related sensors. This leads to the need for an integrated method of storing health-related data, defined as the personal health record (PHR), which could be used by health care providers and patients. This approach could combine EHRs with data gathered from sensors or other wearable computing devices. This unified view of patients’ health could be shared with providers, who may not only use previous health-related records but also expand them with data resulting from their interactions. Another PHR advantage is that patients can interact with their health data, making decisions that may positively affect their health. Objective This work aimed to explore the recent literature related to PHRs by defining the taxonomy and identifying challenges and open questions. In addition, this study specifically sought to identify data types, standards, profiles, goals, methods, functions, and architecture with regard to PHRs. Methods The method to achieve these objectives consists of using the systematic literature review approach, which is guided by research questions using the population, intervention, comparison, outcome, and context (PICOC) criteria. Results As a result, we reviewed more than 5000 scientific studies published in the last 10 years, selected the most significant approaches

    Southern Africa continue to report cases of late stage syphilis, including tabes dorsalis and neurosyphilis, in association with ocular disease.This is the first systematic review of the literature on neurosyphilis in Africa since the beginning of the HIV epidemic. Neurosyphilis continues to be reported as a manifestation of both early and late syphilis, but the methodological quality of the majority of the included studies was poor. Future well-designed prospective studies are needed to better delineate the incidence and clinical spectrum of neurosyphilis in Africa and to better define interactions with HIV in this setting.

  3. Addressing resistance to antibiotics in systematic reviews of antibiotic interventions

    Antibiotics are among the most important interventions in healthcare. Resistance of bacteria to antibiotics threatens the effectiveness of treatment. Systematic reviews of antibiotic treatments often do not address resistance to antibiotics even when data are available in the original studies....... This omission creates a skewed view, which emphasizes short-term efficacy and ignores the long-term consequences to the patient and other people. We offer a framework for addressing antibiotic resistance in systematic reviews. We suggest that the data on background resistance in the original trials should...... controlled trials or systematic reviews....

  4. Introduction to systematic reviews in animal agriculture and veterinary medicine.

    2014-06-01

    This article is the first in a series of six articles related to systematic reviews in animal agriculture and veterinary medicine. In this article, we overview the methodology of systematic reviews and provide a discussion of their use. Systematic reviews differ qualitatively from traditional reviews by explicitly defining a specific review question, employing methods to reduce bias in the selection and inclusion of studies that address the review question (including a systematic and specified search strategy, and selection of studies based on explicit eligibility criteria), an assessment of the risk of bias for included studies and objectively summarizing the results qualitatively or quantitatively (i.e. via meta-analysis). Systematic reviews have been widely used to address human healthcare questions and are increasingly being used in veterinary medicine. Systematic reviews can provide veterinarians and other decision-makers with a scientifically defensible summary of the current state of knowledge on a topic without the need for the end-user to read the vast amount of primary research related to that topic.

    There is ongoing interest in including grey literature in systematic reviews. Including grey literature can broaden the scope to more relevant studies, thereby providing a more complete view of available evidence. Searching for grey literature can be challenging despite greater access through the Internet, search engines and online bibliographic databases. There are a number of publications that list sources for finding grey literature in systematic reviews. However, there is scant information about how searches for grey literature are executed and how it is included in the review process. This level of detail is important to ensure that reviews follow explicit methodology to be systematic, transparent and reproducible. The purpose of this paper is to provide a detailed account of one systematic review team's experience in searching for grey literature and including it throughout the review. We provide a brief overview of grey literature before describing our search and review approach. We also discuss the benefits and challenges of including grey literature in our systematic review, as well as the strengths and limitations to our approach. Detailed information about incorporating grey literature in reviews is important in advancing methodology as review teams adapt and build upon the approaches described.

    Systematic reviews are fundamental decision-making tools for the assessment of the effectiveness of healthcare interventions and for determining future research fields. In the field of hand surgery, so far, there exists only a limited number of systematic reviews. According to the diversity and multitude of hand surgical topics, relevant fields for systematic reviews were identified by means of an expert ranking. A catalogue of 24 topics was extracted from publications of representative hand surgical journals. These topics were categorized and integrated into a questionnaire which was presented to 30 experts in the field of hand surgery. Every single topic had to be rated by marks from 1 (very relevant) to 5 (not relevant). Further topics could have been indicated. Averaging of the marks allowed to define a ranking and a prioritisation of the topics. 29 of 30 questionnaires were returned. The ranking showed scapholunate ligament injury, Kienboeck's disease and scaphoid nonunion to have the highest relevance, followed by 5 other topics dealing with wrist problems. The lowest relevance was attributed to neck fractures of the fifth metacarpal, ulnar collateral ligament injury of the thumb metacarpophalangeal joint and postoperative management following replantation. The results of the presented survey allow for a prioritisation of topics for systematic reviews in hand surgery. The ranking of the topics emphasises the particular relevance of injuries and diseases of the wrist. © Georg Thieme Verlag KG Stuttgart · New York.

    Osteogenesis imperfecta (OI) is a group of genetic disorders, of which Type III is the most severe among survivors. The disease is characterised in particular by bone fragility, decreased bone mass and increased incidence of fractures. Other usual findings are muscle hypotonia, joint hypermobility and short stature. Fractures and weak bones may consequently cause limb and spinal deformity and chronic physical disability. Bisphosphonates have revolutionised the treatment of newborn children with severe OI type III. Surgery is still needed in most patients due to high frequency of the fractures. In this systematic review we describe the present state-of-art in treating the most severe type of OI in newborn and preschool children with their bone fractures.

    Full Text Available Background : Uncontrolled anger while being most commonly associated with personality disorders could also be part of many other conditions such as chronic low back ache and post-traumatic stress disorder. The intensity of anger as an emotional state at a particular time is known as "State Anger," whereas how often angry feelings are experienced over time is known as "Trait Anger." Anger could also manifest as expression of anger toward other persons or objects in the environment (Anger-Out, holding in or suppressing angry feelings (Anger-In and controlling angry feelings by preventing the expression of anger toward other persons or objects in the environment or controlling suppressed angry feelings by calming down or cooling off (Anger Control. Objective : To prove the effectiveness of topiramate in the control of anger as compared to placebo and to disprove that its use leads to psychiatric adverse events by systematically reviewing the available randomized controlled trials. Materials and Methods : The basic search was performed in MEDLINE (1966 through November 2008 combined with the optimal search strategy for randomized controlled trials described in the Cochrane Reviewers′ Handbook. To update this search, we regularly screened citations from PubMed till November 2008 for eligible studies or reviews that might include eligible studies. The Cochrane Central Register of Controlled Trials (CENTRAL was searched using the terms "topiramate" and "anger or aggression." In addition, we screened bibliographies of reviews and identified articles. Randomized clinical trials wherein study participants were aggressive adults were included. Results : We could arrive at a weighted mean difference of -3.16 (-3.64 to -2.68 in State Anger. The reduction in the score was highest in borderline personality disorder (BPD patients as compared to those with low back ache. Trait Anger dropped by -2.93 (-3.49 to -2.37, especially in female BPD patients. Anger In

    2017-01-01

    Systematic reviews have, increasingly, informed policy for almost 3 decades. In many countries, systematic reviews have informed policy for public and population health, paying for health care, increasing the quality and efficiency of interventions, and improving the effectiveness of health sector professionals and the organizations in which they work. Systematic reviews also inform other policy areas: criminal justice, education, social welfare, and the regulation of toxins in the environment. Although the production and use of systematic reviews has steadily increased, many clinicians, public health officials, representatives of commercial organizations, and, consequently, policymakers who are responsive to them, have been reluctant to use these reviews to inform policy; others have actively opposed using them. Systematic reviews could inform policy more effectively with changes to current practices and the assumptions that sustain these practices-assumptions made by researchers and the organizations that employ them, by public and private funders of systematic reviews, and by organizations that finance, set priorities and standards for, and publish them.

    Krueger, Ronald; Shivakumar, Kunigal; Raju, Ivatury S.

    2013-01-01

    Recent developments in fracture mechanics analyses of the interfacial crack problem are reviewed. The intent of the review is to renew the awareness of the oscillatory singularity at the crack tip of a bimaterial interface and the problems that occur when calculating mode mixity using numerical methods such as the finite element method in conjunction with the virtual crack closure technique. Established approaches to overcome the nonconvergence issue of the individual mode strain energy release rates are reviewed. In the recent literature many attempts to overcome the nonconvergence issue have been developed. Among the many approaches found only a few methods hold the promise of providing practical solutions. These are the resin interlayer method, the method that chooses the crack tip element size greater than the oscillation zone, the crack tip element method that is based on plate theory and the crack surface displacement extrapolation method. Each of the methods is validated on a very limited set of simple interface crack problems. However, their utility for a wide range of interfacial crack problems is yet to be established.

  2. Integration of existing systematic reviews into new reviews: identification of guidance needs

    Science.gov (United States)

    2014-01-01

    Background An exponential increase in the number of systematic reviews published, and constrained resources for new reviews, means that there is an urgent need for guidance on explicitly and transparently integrating existing reviews into new systematic reviews. The objectives of this paper are: 1) to identify areas where existing guidance may be adopted or adapted, and 2) to suggest areas for future guidance development. Methods We searched documents and websites from healthcare focused systematic review organizations to identify and, where available, to summarize relevant guidance on the use of existing systematic reviews. We conducted informational interviews with members of Evidence-based Practice Centers (EPCs) to gather experiences in integrating existing systematic reviews, including common issues and challenges, as well as potential solutions. Results There was consensus among systematic review organizations and the EPCs about some aspects of incorporating existing systematic reviews into new reviews. Current guidance may be used in assessing the relevance of prior reviews and in scanning references of prior reviews to identify studies for a new review. However, areas of challenge remain. Areas in need of guidance include how to synthesize, grade the strength of, and present bodies of evidence composed of primary studies and existing systematic reviews. For instance, empiric evidence is needed regarding how to quality check data abstraction and when and how to use study-level risk of bias assessments from prior reviews. Conclusions There remain areas of uncertainty for how to integrate existing systematic reviews into new reviews. Methods research and consensus processes among systematic review organizations are needed to develop guidance to address these challenges. PMID:24956937

    Full Text Available Peter Vestergaard, Susanna vid Streym ThomsenDepartment of Endocrinology and Metabolism C, Aarhus University Hospital, Aarhus, DenmarkAbstract: Several categories of drugs to treat osteoporosis exist in the form of bisphosphonates, strontium, parathyroid hormone, and selective estrogen receptor modulators (SERM. Advantages and disadvantages exist for each category as some patients may, for example, not tolerate bisphosphonates for gastrointestinal side effects, and especially in women in whom osteoporosis is frequent, several options for treatment are needed. The objectives of this review were to critically appraise the effects of bazedoxifene on risk of fractures especially in women at high risk of fractures. A systematic literature search was conducted for studies, especially randomized controlled trials with fractures as end-points. Bazedoxifene is a new member of the SERM group. The literature search identified one randomized controlled trial with fractures as end-point. This was a 3-year randomized double-blind placebo controlled trial in which 7492 postmenopausal women aged 55 to 85 years were randomly allocated to 1 bazedoxifene (20 [n = 1886] or 40 [n = 1872] mg/day; 2 raloxifene (60 mg/day, n = 1849; or 3 placebo (n = 1885. The risk of vertebral fractures decreased with both 20 (HR 0.58, 95% CI 0.38 to 0.89 and 40 (HR 0.63, 95% CI 0.42 to 0.96 mg of bazedoxifene per day compared to placebo. There was no reduction in non-vertebral fractures. A subgroup of women with a priori high risk of fractures was identified post hoc. In this subgroup there was a reduction in the risk of non-vertebral fractures with the 20 mg dose of bazedoxifene compared to placebo (HR 0.50, 95% CI 0.28 to 0.90. In the 40 mg bazedoxifene group no significant reduction in non-vertebral fractures was seen in this subgroup (HR 0.70, 95% CI 0.40 to 1.20. In general post-hoc defined subgroup analyses should be interpreted with caution. However, the results indicate that

    2017-01-01

    Introduction Bipolar spectrum disorder is a chronic, episodic illness, associated with significant personal, social and economic burden. It is estimated to affect ∼2.4% of the population worldwide and is commonly associated with psychological and/or physiological comorbidities. Osteoporosis is one such comorbidity, a disease of bone that is asymptomatic until a fracture occurs. This systematic review attempts to capture, collate, assess and discuss the literature investigating the association between bipolar spectrum disorder and bone health. Methods and analysis We aim to identify articles that investigate the association between bipolar spectrum disorder and bone health in adults by systematically searching the MEDLINE, PubMed, OVID and CINAHL databases. Two independent reviewers will determine eligibility of studies according to predetermined criteria, and methodological quality will be assessed using a previously published scoring system. A meta-analysis will be conducted, and statistical methods will be used to identify and control for heterogeneity, if possible. If numerical syntheses are prevented due to statistical heterogeneity, a best evidence synthesis will be conducted to assess the level of evidence for associations between bipolar spectrum disorder and bone health. Ethics and dissemination Ethical permission will not be required for this systematic review since only published data will be used. This protocol will be registered with PROSPERO. Findings of the review will be published in a peer-reviewed scientific journal, and will be presented to clinical and population health audiences at national and international conferences.

    Full Text Available A systematic review is a summary of existing evidence that answers a specific clinical question, contains a thorough, unbiased search of the relevant literature, explicit criteria for assessing studies and structured presentation of the results. A systematic review that incorporates quantitative pooling of similar studies to produce an overall summary of treatment effects is a meta-analysis. A systematic review should have clear, focused clinical objectives containing four elements expressed through the acronym PICO ( Patient, group of patients, or problem, an Intervention, a Comparison intervention and specific O utcomes. Explicit and thorough search of the literature is a pre-requisite of any good systematic review. Reviews should have pre-defined explicit criteria for what studies would be included and the analysis should include only those studies that fit the inclusion criteria. The quality (risk of bias of the primary studies should be critically appraised. Particularly the role of publication and language bias should be acknowledged and addressed by the review, whenever possible. Structured reporting of the results with quantitative pooling of the data must be attempted, whenever appropriate. The review should include interpretation of the data, including implications for clinical practice and further research. Overall, the current quality of reporting of systematic reviews remains highly variable.

    Full Text Available Abstract Systematic reviews have become increasingly critical to informing healthcare policy; however, they remain a time-consuming and labor-intensive activity. The extraction of data from constituent studies comprises a significant portion of this effort, an activity which is often needlessly duplicated, such as when attempting to update a previously conducted review or in reviews of overlapping topics. In order to address these inefficiencies, and to improve the speed and quality of healthcare policy- and decision-making, we have initiated the development of the Systematic Review Data Repository, an open collaborative Web-based repository of systematic review data. As envisioned, this resource would serve as both a central archive and data extraction tool, shared among and freely accessible to organizations producing systematic reviews worldwide. A suite of easy-to-use software tools with a Web frontend would enable researchers to seamlessly search for and incorporate previously deposited data into their own reviews, as well as contribute their own. In developing this resource, we identified a number of technical and non-technical challenges, as well as devised a number of potential solutions, including proposals for systems and software tools to assure data quality, stratify and control user access effectively and flexibly accommodate all manner of study data, as well as means by which to govern and foster adoption of this new resource. Herein we provide an account of the rationale and development of the Systematic Review Data Repository thus far, as well as outline its future trajectory.

    Systematic reviews provide a method for collating and synthesizing research, and are used to inform healthcare decision making by clinicians, consumers and policy makers. A core component of many systematic reviews is a meta-analysis, which is a statistical synthesis of results across studies. In this review article, we introduce meta-analysis, focusing on the different meta-analysis models, their interpretation, how a model should be selected and discuss potential threats to the validity of meta-analyses. We illustrate the application of meta-analysis using data from a review examining the effects of early use of inhaled corticosteroids in the emergency department treatment of acute asthma.

  18. Better duplicate detection for systematic reviewers: evaluation of Systematic Review Assistant-Deduplication Module.

    2015-01-14

    A major problem arising from searching across bibliographic databases is the retrieval of duplicate citations. Removing such duplicates is an essential task to ensure systematic reviewers do not waste time screening the same citation multiple times. Although reference management software use algorithms to remove duplicate records, this is only partially successful and necessitates removing the remaining duplicates manually. This time-consuming task leads to wasted resources. We sought to evaluate the effectiveness of a newly developed deduplication program against EndNote. A literature search of 1,988 citations was manually inspected and duplicate citations identified and coded to create a benchmark dataset. The Systematic Review Assistant-Deduplication Module (SRA-DM) was iteratively developed and tested using the benchmark dataset and compared with EndNote's default one step auto-deduplication process matching on ('author', 'year', 'title'). The accuracy of deduplication was reported by calculating the sensitivity and specificity. Further validation tests, with three additional benchmarked literature searches comprising a total of 4,563 citations were performed to determine the reliability of the SRA-DM algorithm. The sensitivity (84%) and specificity (100%) of the SRA-DM was superior to EndNote (sensitivity 51%, specificity 99.83%). Validation testing on three additional biomedical literature searches demonstrated that SRA-DM consistently achieved higher sensitivity than EndNote (90% vs 63%), (84% vs 73%) and (84% vs 64%). Furthermore, the specificity of SRA-DM was 100%, whereas the specificity of EndNote was imperfect (average 99.75%) with some unique records wrongly assigned as duplicates. Overall, there was a 42.86% increase in the number of duplicates records detected with SRA-DM compared with EndNote auto-deduplication. The Systematic Review Assistant-Deduplication Module offers users a reliable program to remove duplicate records with greater sensitivity

    Systematic reviews and maps should be based on the best available evidence, and reviewers should make all reasonable efforts to source and include potentially relevant studies. However, reviewers may not be able to consider all existing evidence, since some data and studies may not be publicly available. Including non-public studies in reviews provides a valuable opportunity to increase systematic review/map comprehensiveness, potentially mitigating negative impacts of publication bias. Studies may be non-public for many reasons: some may still be in the process of being published (publication can take a long time); some may not be published due to author/publisher restrictions; publication bias may make it difficult to publish non-significant or negative results. Here, we consider what forms these non-public studies may take and the implications of including them in systematic reviews and maps. Reviewers should carefully consider the advantages and disadvantages of including non-public studies, weighing risks of bias against benefits of increased comprehensiveness. As with all systematic reviews and maps, reviewers must be transparent about methods used to obtain data and avoid risks of bias in their synthesis. We make tentative suggestions for reviewers in situations where non-public data may be present in an evidence base.

    Objective: Despite recent increases in the volume of research in professional rugby union, there is little consensus on the epidemiology of injury in adolescent players. We undertook a systematic review to determine the incidence, severity, and nature of injury in adolescent rugby union players. Data Sources: In April 2009, we performed a computerized literature search on PubMed, Embase, and Cochrane Controlled Trials Register (via Ovid). Population-specific and patient-specific search terms were combined in the form of MEDLINE subject headings and key words (wound$ and injur$, rugby, adolescent$). These were supplemented with related-citation searches on PubMed and bibliographic tracking of primary and review articles. Study Selection: Prospective epidemiologic studies in adolescent rugby union players. Data Synthesis: A total of 15 studies were included, and the data were analyzed descriptively. Two independent reviewers extracted key study characteristics regarding the incidence, severity, and nature of injuries and the methodologic design. Conclusions: Wide variations existed in the injury definitions and data collection procedures. The incidence of injury necessitating medical attention varied with the definition, from 27.5 to 129.8 injuries per 1000 match hours. The incidence of time-loss injury (>7 days) ranged from 0.96 to 1.6 per 1000 playing hours and from 11.4/1000 match hours (>1 day) to 12–22/1000 match hours (missed games). The highest incidence of concussion was 3.3/1000 playing hours. No catastrophic injuries were reported. The head and neck, upper limb, and lower limb were all common sites of injury, and trends were noted toward greater time loss due to upper limb fractures or dislocations and knee ligament injuries. Increasing age, the early part of the playing season, and the tackle situation were most closely associated with injury. Future injury-surveillance studies in rugby union must follow consensus guidelines to facilitate interstudy

    The optimal duration of osteoporosis treatment is controversial. As opposed to bisphosphonates, denosumab does not incorporate into bone matrix and bone turnover is not suppressed after its cessation. Recent reports imply that denosumab discontinuation may lead to an increased risk of multiple vertebral fractures. The European Calcified Tissue Society (ECTS) formed a working group to perform a systematic review of existing literature on the effects of stopping denosumab and provide advice on management. Data from phase 2 and 3 clinical trials underscore a rapid decrease of bone mineral density (BMD) and a steep increase in bone turnover markers (BTMs) after discontinuation of denosumab. Clinical case series report multiple vertebral fractures after discontinuation of denosumab and a renewed analysis of FREEDOM and FREEDOM Extension Trial suggests, albeit does not prove, that the risk of multiple vertebral fractures may be increased when denosumab is stopped due to a rebound increase in bone resorption. There appears to be an increased risk of multiple vertebral fractures after discontinuation of denosumab although strong evidence for such an effect and for measures to prevent the occurring bone loss is lacking. Clinicians and patients should be aware of this potential risk. Based on available data, a re-evaluation should be performed after 5years of denosumab treatment. Patients considered at high fracture risk should either continue denosumab therapy for up to 10years or be switched to an alternative treatment. For patients at low risk, a decision to discontinue denosumab could be made after 5years, but bisphosphonate therapy should be considered to reduce or prevent the rebound increase in bone turnover. However, since the optimal bisphosphonate regimen post-denosumab is currently unknown continuation of denosumab can also be considered until results from ongoing trials become available. Based on current data, denosumab should not be stopped without considering

    2017-01-01

    Objective Our objective was to evaluate quality of conduct and reporting of published systematic reviews and meta-analyses in paediatric surgery. We also aimed to identify characteristics predictive of review quality. Background Systematic reviews summarise evidence by combining sources, but are potentially prone to bias. To counter this, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) was published to aid in reporting. Similarly, the Assessing the Methodological Quality of Systematic Reviews (AMSTAR) measurement tool was designed to appraise methodology. The paediatric surgical literature has seen an increasing number of reviews over the past decade, but quality has not been evaluated. Methods Adhering to PRISMA guidelines, we performed a systematic review with a priori design to identify systematic reviews and meta-analyses of interventions in paediatric surgery. From 01/2010 to 06/2016, we searched: MEDLINE, EMBASE, Cochrane, Centre for Reviews and Dissemination, Web of Science, Google Scholar, reference lists and journals. Two reviewers independently selected studies and extracted data. We assessed conduct and reporting using AMSTAR and PRISMA. Scores were calculated as the sum of reported items. We also extracted author, journal and article characteristics, and used them in exploratory analysis to determine which variables predict quality. Results 112 articles fulfilled eligibility criteria (53 systematic reviews; 59 meta-analyses). Overall, 68% AMSTAR and 56.8% PRISMA items were reported adequately. Poorest scores were identified with regards a priori design, inclusion of structured summaries, including the grey literature, citing excluded articles and evaluating bias. 13 reviews were pre-registered and 6 in PRISMA-endorsing journals. The following predicted quality in univariate analysis:, word count, Cochrane review, journal h-index, impact factor, journal endorses PRISMA, PRISMA adherence suggested in author guidance

    Full Text Available Introduction: Since between 25-30% bone fractures, and 60% hip fractures in the general population are common in the subgroup which correspond to very old women. This happens due to the high predominance of primary osteoporosis and the incidence of falls which are characteristic of such group; thus, we have decided to investigate, through a systematic revision of the bibliography, the value of strontium in the prevention of bone fractures caused by falls in very old patients who suffer from primary osteoporosis. Material and Method: A systematic revision of the literature was carried out following the recommendations of the Cochrane methodology. Out of the 8 documents initially recovered, only two were included (2 independent reviewers selected, evaluated and extracted the data from the included tests since such tests were the only ones which complied with the eligibility criteria to be tests performed on a population of very old patients: older than 74 years old, thus reaching a total amount of 2616 patients who took part in this test. Results: Despite the abundance of information in favour of the treatment using strontium, there is a relative risk in the case of non-vertebral fractures one year after treatment which goes through unit: 0.58 [0.32, 1.06]. Regarding the risk of fracture at the hip level, there are certain differences when it is compared with the aforementioned data. On the one hand, the reduction of the risk of fractures (32% after 3 years of treatment with strontium ranelate documented by the Seeman test 2006 did not reach statistical significance (p=0.112, and its relative risk goes through unit: 0.68 [0.45, 1.05] Nevertheless, the Reginster 2008 test showed that after 5 years of treatment with strontium ranelate there was a bigger reduction (43% which was statistically significant (p=0.036 (Tables 1 and 4. Such data could mean that the hip bone may need a longer period of exposure to strontium to benefit from an effective

    Traumatic periprosthetic fractures adjacent a hip resurfacing prosthesis are rare. When proximal fractures are encountered the obvious surgical solution is to revise to a large head stemmed femoral component. A previously well functioning implant may however be retained as various non-operative and operative treatment options exist. This paper reports the case history of a traumatic periprosthetic fracture successfully treated with cannulated screw fixation and reviews the current literature.

    Full Text Available In nature, shooting mechanisms are used for a variety of purposes, including prey capture, defense, and reproduction. This review offers insight into the working principles of shooting mechanisms in fungi, plants, and animals in the light of the specific functional demands that these mechanisms fulfill.We systematically searched the literature using Scopus and Web of Knowledge to retrieve articles about solid projectiles that either are produced in the body of the organism or belong to the body and undergo a ballistic phase. The shooting mechanisms were categorized based on the energy management prior to and during shooting.Shooting mechanisms were identified with projectile masses ranging from 1·10-9 mg in spores of the fungal phyla Ascomycota and Zygomycota to approximately 10,300 mg for the ballistic tongue of the toad Bufo alvarius.

    Fracture networks play a more significant role in conducting fluid flow and solute transport in fractured rock masses, comparing with that of the rock matrix. Accurate estimation of the permeability of fracture networks would help researchers and engineers better assess the performance of projects associated with fluid flow in fractured rock masses. This study provides a review of previous works that have focused on the estimation of equivalent permeability of two-dimensional (2-D) discrete fracture networks (DFNs) considering the influences of geometric properties of fractured rock masses. Mathematical expressions for the effects of nine important parameters that significantly impact on the equivalent permeability of DFNs are summarized, including (1) fracture-length distribution, (2) aperture distribution, (3) fracture surface roughness, (4) fracture dead-end, (5) number of intersections, (6) hydraulic gradient, (7) boundary stress, (8) anisotropy, and (9) scale. Recent developments of 3-D fracture networks are briefly reviewed to underline the importance of utilizing 3-D models in future research.

    Review articles can provide valuable summaries of the ever-increasing volume of primary research in conservation biology. Where findings may influence important resource-allocation decisions in policy or practice, there is a need for a high degree of reliability when reviewing evidence. However, traditional literature reviews are susceptible to a number of biases during the identification, selection, and synthesis of included studies (e.g., publication bias, selection bias, and vote counting). Systematic reviews, pioneered in medicine and translated into conservation in 2006, address these issues through a strict methodology that aims to maximize transparency, objectivity, and repeatability. Systematic reviews will always be the gold standard for reliable synthesis of evidence. However, traditional literature reviews remain popular and will continue to be valuable where systematic reviews are not feasible. Where traditional reviews are used, lessons can be taken from systematic reviews and applied to traditional reviews in order to increase their reliability. Certain key aspects of systematic review methods that can be used in a context-specific manner in traditional reviews include focusing on mitigating bias; increasing transparency, consistency, and objectivity, and critically appraising the evidence and avoiding vote counting. In situations where conducting a full systematic review is not feasible, the proposed approach to reviewing evidence in a more systematic way can substantially improve the reliability of review findings, providing a time- and resource-efficient means of maximizing the value of traditional reviews. These methods are aimed particularly at those conducting literature reviews where systematic review is not feasible, for example, for graduate students, single reviewers, or small organizations. © 2015 Society for Conservation Biology.

    2010-03-01

    Full Text Available AIM: Pelvic and acetabular fractures are associated with high-energy trauma. The aim of this study was to identify factors that are associated with specific clinical outcomes following treatment for these fractures. METHODS: A consecutive series of 30 patients who had surgical intervention for either pelvic or acetabular fractures formed the sample for this study. Clinical variables reviewed were: age, associated injuries, number of surgical procedures, time to surgery and post-operative complications. Clinical outcomes were assessed using Matta’s grading of post- operative fracture reduction alignment, and functional outcomes were graded using D'Aubigne & Postel’s Hip scoring system. RESULTS: Study subjects included twelve pelvic fractures and eighteen acetabular fractures. Patients older than 50 years of age had poorer hip scores despite surgery. Earlier fracture fixation (within five days was associated with better hip scores. Patients with acetabular fractures generally had better functional outcomes than patients with pelvic fractures (mean hip score 15.0 vs. 13.5. Closer anatomical reduction of acetabular fractures was associated with better functional outcome. CONCLUSION: Improved clinical outcomes are associated with younger age, fewer concomitant injuries, shorter time interval to surgery and more closely approximated anatomical fracture reduction.

    2013-01-01

    Systematic reviews are currently favored methods of evaluating research in order to reach conclusions regarding medical practice. The need for such reviews is necessitated by the fact that no research is perfect and experts are prone to bias. By combining many studies that fulfill specific criteria, one hopes that the strengths can be multiplied and thus reliable conclusions attained. Potential flaws in this process include the assumptions that underlie the research under examination. If the assumptions, or axioms, upon which the research studies are based, are untenable either scientifically or logically, then the results must be highly suspect regardless of the otherwise high quality of the studies or the systematic reviews. We outline recent criticisms of animal-based research, namely that animal models are failing to predict human responses. It is this failure that is purportedly being corrected via systematic reviews. We then examine the assumption that animal models can predict human outcomes to perturbations such as disease or drugs, even under the best of circumstances. We examine the use of animal models in light of empirical evidence comparing human outcomes to those from animal models, complexity theory, and evolutionary biology. We conclude that even if legitimate criticisms of animal models were addressed, through standardization of protocols and systematic reviews, the animal model would still fail as a predictive modality for human response to drugs and disease. Therefore, systematic reviews and meta-analyses of animal-based research are poor tools for attempting to reach conclusions regarding human interventions.

    Chinese biomedical databases contain a large number of publications available to systematic reviewers, but it is unclear whether they are used for synthesizing the available evidence. We report a case of two systematic reviews on the accuracy of anti-cyclic citrullinated peptide for diagnosing rheumatoid arthritis. In one of these, the authors did not search Chinese databases; in the other, they did. We additionally assessed the extent to which Cochrane reviewers have searched Chinese databases in a systematic overview of the Cochrane Library (inception to 2014). The two diagnostic reviews included a total of 269 unique studies, but only 4 studies were included in both reviews. The first review included five studies published in the Chinese language (out of 151) while the second included 114 (out of 118). The summary accuracy estimates from the two reviews were comparable. Only 243 of the published 8,680 Cochrane reviews (less than 3%) searched one or more of the five major Chinese databases. These Chinese databases index about 2,500 journals, of which less than 6% are also indexed in MEDLINE. All 243 Cochrane reviews evaluated an intervention, 179 (74%) had at least one author with a Chinese affiliation; 118 (49%) addressed a topic in complementary or alternative medicine. Although searching Chinese databases may lead to the identification of a large amount of additional clinical evidence, Cochrane reviewers have rarely included them in their search strategy. We encourage future initiatives to evaluate more systematically the relevance of searching Chinese databases, as well as collaborative efforts to allow better incorporation of Chinese resources in systematic reviews.

    Various treatment modalities are available for cutaneous lichen planus. Pubmed, EMBASE, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Database of Abstracts of Reviews of Effects, and Health Technology Assessment Database were searched for all the systematic reviews and randomized controlled trials related to cutaneous lichen planus. Two systematic reviews and nine relevant randomized controlled trials were identified. Acitretin, griseofulvin, hydroxychloroquine and narrow band ultraviolet B are demonstrated to be effective in the treatment of cutaneous lichen planus. Sulfasalazine is effective, but has an unfavorable safety profile. KH1060, a vitamin D analogue, is not beneficial in the management of cutaneous lichen planus. Evidence from large scale randomized trials demonstrating the safety and efficacy for many other treatment modalities used to treat cutaneous lichen planus is simply not available.

    Full Text Available BACKGROUND Mandible fractures are a frequent injury because of the mandible's prominence and relative lack of support. The purpose of this study is to clinically determine the most common sites and the prevalence of isolated fracture mandible in our scenario and determine most common traumatic aetiology factor responsible for fracture mandible. Numerous investigators have reported studies on populations on all continents; fractures of the mandible have been reported to account for 36-70% of all maxillofacial fractures. All reports apparently show a higher frequency in males aged 21-30 yrs. There is an emerging trend towards an increase in the frequency of violent mechanisms of fracture and in the proportion of adolescents and young adults sustaining such injuries. MATERIALS AND METHODS Patients treated at the Otorhinolaryngology Head and Neck Surgery Department of B.D.B.A. Hospital from a period between January 2014 to January2016 were (retrospectively evaluated with respect to age groups, gender, aetiology, localisation, type of fractures and treatment. RESULTS Total number of patients 38, 2 patients had bilateral fracture, males 27 (71.05%, females 11 (28.95%. Anatomical location symphysis and parasymphysis 14 (35%, condylar 12 (30%, body 7 (17.5%, angle 6 (15%, coronoid 1 (2.5%. Aetiological factors road traffic accidents 19 (50%, assault 13 (34.24%, fall 3 (7.89%, work-related trauma 2 (5.26%, sports trauma 1 (2.6%. CONCLUSION This study indicates that most common fracture in adult patient were symphysis and parasymphysis, second most common were condylar followed by body fracture and angle fracture. The most common cause of the injury maybe road traffic accidents, second most common assault followed by work related injuries, fall and sports injuries.

    2012-09-15

    The purpose of this study was to review the MRI examinations of a large group of low-energy trauma patients in whom pelvic MRI had detected radiographically occult fractures, in order to characterize prevailing fracture patterns and determine how often co-existing proximal femoral and pelvic fractures were observed. All patients having pelvic MRI over 5 years were identified. Word-search software selected 269 MRI reports containing the term 'fracture'. Further scrutiny identified 168 with diagnosis of fracture. MRI request and imaging record review identified 102 low-energy trauma cases that had MRI for clinical suspicion of fracture despite normal radiographs. Sixty-six cases were excluded for the following reasons: no expressed clinical suspicion of occult fracture; history suggesting high-energy trauma; skeletal co-morbidity hindering acute fracture identification; interval more than 2 weeks between radiographs and MRI. The 102 study MRI examinations, which employed a limited two-sequence protocol, were reviewed. Any fracture that had not been appreciated on radiographs was recorded and characterized as femoral, pelvic, or co-existing femoral and pelvic fractures. The 102 study cases had a median age of 82 years. The median interval between pelvic radiographs and MRI was 3 days. MRI showed undiagnosed femoral fracture in 48/102 cases (47.1%), sacral fracture in 41/102 (40.2%), and pubic fracture in 55/102 (53.9%). In 11/102 cases (10.8%), MRI showed undiagnosed fractures of both proximal femur and pelvic ring (seven sacral, six pubic bone, two other site fractures). In 10/11 cases with co-existing femoral and pelvic fractures, the femoral fracture was incomplete. Limited pelvic MRI found a high prevalence of radiographically occult femoral and pelvic fractures in low-energy trauma patients, with clinical suspicion of fracture despite normal radiographs. Co-existing occult femoral and pelvic ring fractures were commonly observed, and in such cases, the

    Full Text Available Mandibular fractures are relatively less frequent in children when compared to adults, which may be due to the child′s protected anatomic features and infrequent exposure of children to alcohol related traffic accidents. Treatment principles of mandibular fractures differ from that of adults due to concerns regarding mandibular growth and development of dentition. A case of a 4.5-year-old boy with fractured body of mandible managed by closed reduction using open occlusal acrylic splint and circum mandibular wiring is presented. This article also provides a review of literature regarding the management of mandibular body fracture in young children.

    Psychological stress has been shown to delay wound healing. Several trials have investigated whether psychological interventions can improve wound healing, but to date, this evidence base has not been systematically synthesized. The objective was to conduct a systematic review of randomized controlled trials in humans investigating whether psychological interventions can enhance wound healing. A systematic review was performed using PsychINFO, CINAHL, Web of Science, and MEDLINE. The searches included all papers published in English up until September 2016. The reference lists of relevant papers were screened manually to identify further review articles or relevant studies. Nineteen studies met inclusion criteria and were included in the review. Fifteen of nineteen studies were of high methodological quality. Six studies were conducted with acute experimentally created wounds, five studies with surgical patients, two studies with burn wounds, two studies with fracture wounds, and four studies were conducted with ulcer wounds. Post-intervention standardized mean differences (SMD) between groups across all intervention types ranged from 0.13 to 3.21, favouring improved healing, particularly for surgical patients and for relaxation interventions. However, there was some evidence for publication bias suggesting negative studies may not have been reported. Due to the heterogeneity of wound types, population types, and intervention types, it is difficult to pool effect sizes across studies. Current evidence suggests that psychological interventions may aid wound healing. Although promising, more research is needed to assess the efficacy of each intervention on different wound types. Statement of contribution What is already known on this subject? Psychological stress negatively affects wound healing. A number of studies have investigated whether psychological interventions can improve healing. However, no systematic reviews have been conducted. What does this study add

  20. Systematic reviews, overviews of reviews and comparative effectiveness reviews: a discussion of approaches to knowledge synthesis.

    Hartling, Lisa; Vandermeer, Ben; Fernandes, Ricardo M

    2014-06-01

    The Cochrane Collaboration has been at the forefront of developing methods for knowledge synthesis internationally. We discuss three approaches to synthesize evidence for healthcare interventions: systematic reviews (SRs), overviews of reviews and comparative effectiveness reviews. We illustrate these approaches with examples from knowledge syntheses on interventions for bronchiolitis, a common acute paediatric condition. Some of the differences among these approaches are subtle and methods are not necessarily mutually exclusive to a single review type. Systematic reviews bring together evidence from multiple studies in a rigorous fashion for a single intervention or group of interventions. Systematic reviews, as they have developed within healthcare, often focus on single or select interventions and direct pairwise comparisons; therefore, end-users may need to read several individual SRs to inform decision making. Overviews of reviews compile information from multiple SRs relevant to a single health problem. Overviews provide the end-user with a quick overview of the available evidence; however, overviews are dependent on the methods and decisions employed at the SR level. Furthermore, overviews do not often integrate evidence from different SRs quantitatively. Comparative effectiveness reviews, as we define them here, synthesize relevant evidence from individual studies to describe the relative benefits (or harms) of a range of interventions. Comparative effectiveness reviews may use statistical methods (network meta-analysis) to incorporate direct and indirect evidence; therefore, they can provide stronger inferences about the relative effectiveness (or safety) of interventions. While potentially more expensive and time-consuming to produce, a comparative effectiveness review provides a synthesis of a range of interventions for a given condition and the relative efficacy across interventions using consistent and standardized methodology.

    2017-01-01

    Objetives There have been several systematic reviews(SRs) on whether periodontal treatment for an individual with both periodontal disease and diabetes can improve diabetes outcomes. The purpose of this investigation was to conduct a systematic review (SR) of previous meta-analyses, and to assess the methodological quality of the SRs examining the effects of periodontal treatment and diabetes. (PROSPERO Registration # CRD 42015023470). Study Design We searched five electronic databases and identified previous meta-analyses of randomized controlled trials published through July 2015. In cases where the meta-analysis did not meet our criteria, the meta-analyses were recalculated. General characteristics of each included trial were abstracted, analyzed, and compared. The mean difference, 95% confidence intervals (CIs) and the I2 statistic were abstracted or recalculated. The Assessment of Multiple Systematic Reviews Instrument (AMSTAR) was used to assess methodological quality. Results Of the 475 citations screened, nine systematic reviews were included. In total, 13 meta-analyses included in nine SRs were examined. In comparability analyses, meta-analyses in four SRs did not meet our criteria, and were recalcuated. Of these 13 meta-analyses, 10 suggested significant effects of periodontal treatment on HbA1c improvement. Mean differences found in the 13 meta-analyses ranged from -0.93 to 0.13. AMSTAR assessment revealed six SRs with moderate and three with high overall quality. Conclusions We can conclude that there is a significant effect of periodontal treatment on improvement of HbA1c in diabetes patients, although the effect size is extremely small. In addition to the small effect size, not all SRs could be considered of high quality.

    2011-09-01

    Accurate diagnosis is crucial in effectively managing and treating both the radial and carpal fractures. Injuries to the carpal bones are not usually associated with fractures of the distal radius; however, the presence of a distal radius fracture does not preclude an associated carpal injury. The purpose of this review article is to compile cases of past reported distal radius fractures and simultaneous carpal injuries to restate its low prevalence within the pediatric population while still serving as a collective reference for management and treatment. After an electronic literature search was performed, we identified 18 published articles and 28 cases dealing with combined distal radial and carpal bones injuries in the pediatric population. As the mechanism of injury is similar for both fractures, despite the low incidence, orthopedic surgeons need to rule out carpal injury with a distal forearm fracture. Failure to treat both injuries appropriately may result in an unsatisfactory clinical result.

    Scientific software plays an important role in critical decision making, for example making weather predictions based on climate models, and computation of evidence for research publications. Recently, scientists have had to retract publications due to errors caused by software faults. Systematic testing can identify such faults in code. This study aims to identify specific challenges, proposed solutions, and unsolved problems faced when testing scientific software. We conducted a systematic literature survey to identify and analyze relevant literature. We identified 62 studies that provided relevant information about testing scientific software. We found that challenges faced when testing scientific software fall into two main categories: (1) testing challenges that occur due to characteristics of scientific software such as oracle problems and (2) testing challenges that occur due to cultural differences between scientists and the software engineering community such as viewing the code and the model that it implements as inseparable entities. In addition, we identified methods to potentially overcome these challenges and their limitations. Finally we describe unsolved challenges and how software engineering researchers and practitioners can help to overcome them. Scientific software presents special challenges for testing. Specifically, cultural differences between scientist developers and software engineers, along with the characteristics of the scientific software make testing more difficult. Existing techniques such as code clone detection can help to improve the testing process. Software engineers should consider special challenges posed by scientific software such as oracle problems when developing testing techniques.

    Fluoropyrimidine (FU) and platinum-based chemotherapies are greatly complicated by their associated toxicities. This umbrella systematic review synthesized all systematic reviews that investigated associations between germline variations and toxicity, with the aim of informing personalized medicine. Systematic reviews are important in pharmacogenetics where false positives are common. Four systematic reviews were identified for FU-induced toxicity and three for platinum. Polymorphisms of DPYD and TYMS, but not MTHFR, were statistically significantly associated with FU-induced toxicity (although only DPYD had clinical significance). For platinum, GSTP1 was found to not be associated with toxicity. This umbrella systematic review has synthesized the best available evidence on the pharmacogenetics of FU and platinum toxicity. It provides a useful reference for clinicians and identifies important research gaps.

  10. A review of crosslinked fracturing fluids prepared with produced water

    2016-12-01

    Full Text Available The rapidly increasing implementations of oilfield technologies such as horizontal wells and multistage hydraulic fracturing, particularly in unconventional formations, have expanded the need for fresh water in many oilfield locations. In the meantime, it is costly for services companies and operators to properly dispose large volumes of produced water, generated annually at about 21 billion barrels in the United States alone. The high operating costs in obtaining fresh water and dealing with produced water have motivated scientists and engineers, especially in recent years, to use produced water in place of fresh water to formulate well treatment fluids. The objective of this brief review is to provide a summary of the up-to-date technologies of reusing oilfield produced water in preparations of a series of crosslinked fluids implemented mainly in hydraulic fracturing operations. The crosslinked fluids formulated with produced water include borate- and metal-crosslinked guar and derivatized guar fluids, as well as other types of crosslinked fluid systems such as crosslinked synthetic polymer fluids and crosslinked derivatized cellulose fluids. The borate-crosslinked guar fluids have been successfully formulated with produced water and used in oilfield operations with bottomhole temperatures up to about 250 °F. The produced water sources involved showed total dissolved solids (TDS up to about 115,000 mg/L and hardness up to about 11,000 mg/L. The metal-crosslinked guar fluids prepared with produced water were successfully used in wells at bottomhole temperatures up to about 250 °F, with produced water TDS up to about 300,000 mg/L and hardness up to about 44,000 mg/L. The Zr-crosslinked carboxymethyl hydroxypropyl guar (CMHPG fluids have been successfully made with produced water and implemented in operations with bottomhole temperatures at about 250+ °F, with produced water TDS up to about 280,000 mg/L and hardness up to about 91,000

  12. Teriparatide (recombinant human parathyroid hormone 1-34 in postmenopausal women with osteoporosis: systematic review

    Directory of Open Access Journals (Sweden)

    Virgínia Fernandes Moça Trevisani

    Full Text Available CONTEXT AND OBJECTIVE: Osteoporosis is defined as a disease characterized by low bone mass and deterioration of the bone tissue microarchitecture. Teriparatide stimulates the formation and action of osteoblasts, which are responsible for bone formation, thus promoting bone tissue increase. The aim was to assess the effectiveness and safety of teriparatide for treating postmenopausal osteoporosis. METHODS: A systematic review was conducted using the Cochrane Collaboration methodology. RESULTS: 1 Teriparatide 20 µg or 40 µg versus placebo: there was a benefit from teriparatide, considering the following outcomes: reduction in the number of new vertebral and non-vertebral fractures, and increased whole-body, lumbar and femoral bone mineral density. 2 Teriparatide 40 µg versus alendronate 10 mg/day for 14 months: there was no statistical difference regarding the incidence of new vertebral or non-vertebral fractures, although in the group that received teriparatide there was greater bone mineral density increase in the whole body, lumbar column and femur. 3 Estrogen plus teriparatide 25 µg versus estrogen: there was a benefit, considering the following outcomes: reduction in the number of new vertebral fractures, and increased whole-body, lumbar and femoral bone mineral density after three years. CONCLUSIONS: When teriparatide is intermittently administered in low doses, it reduces the incidence of vertebral fractures (67% and non-vertebral fractures (38% and increases bone mineral density in the lumbar column and femur. There is a need for studies with longer observation in order to allow conclusions regarding the safety and duration of the therapeutic effects.

  13. Obesity and Healthcare Avoidance: A Systematic Review

    Directory of Open Access Journals (Sweden)

    Robert D McGuigan

    2015-03-01

    Full Text Available This review addresses the issue of health care avoidance and obesity. English language journal articles published between 1990 and 2012 that addressed the review question|“is being overweight or obese an unrecognized factor in healthcare avoidance?” were located using major databases. A modified JADAD scoring system was then used to assess papers. Ten papers were identified which directly addressed the review question. A positive relationship exists between obesity and healthcare avoidance. The major contributory factors were being female, have a diagnosed mental health problem and perceived or actual bias and discrimination by health professionals. The review also highlights the importance of the relationship between healthcare professionals and their patients, and the physical environment in which interactions occur as these may contribute to avoidance behaviors. Concern about obesity is rising and while there has been much discussion about strategies to reduce obesity this review highlights the need for thinking more broadly about the way in which overweight and obese individuals interact with preventative health strategies.

    Aromatherapy is the therapeutic use of essential oil from herbs, flowers, and other plants. The aim of this overview was to provide an overview of systematic reviews evaluating the effectiveness of aromatherapy. We searched 12 electronic databases and our departmental files without restrictions of time or language. The methodological quality of all systematic reviews was evaluated independently by two authors. Of 201 potentially relevant publications, 10 met our inclusion criteria. Most of the systematic reviews were of poor methodological quality. The clinical subject areas were hypertension, depression, anxiety, pain relief, and dementia. For none of the conditions was the evidence convincing. Several SRs of aromatherapy have recently been published. Due to a number of caveats, the evidence is not sufficiently convincing that aromatherapy is an effective therapy for any condition.

    Antibiotics are among the most important interventions in healthcare. Resistance of bacteria to antibiotics threatens the effectiveness of treatment. Systematic reviews of antibiotic treatments often do not address resistance to antibiotics even when data are available in the original studies. This omission creates a skewed view, which emphasizes short-term efficacy and ignores the long-term consequences to the patient and other people. We offer a framework for addressing antibiotic resistance in systematic reviews. We suggest that the data on background resistance in the original trials should be reported and taken into account when interpreting results. Data on emergence of resistance (whether in the body reservoirs or in the bacteria causing infection) are important outcomes. Emergence of resistance should be taken into account when interpreting the evidence on antibiotic treatment in randomized controlled trials or systematic reviews.

The methodological quality of the systematic reviews was evaluated using recommended standard criteria from AMSTAR. For each review, improper use of causal language in the description of their main results/conclusion was evaluated. Altogether, 1,044 review titles were identified, 144 were read in their entirety, and 27 were included. Based on the systematic reviews with the best methodological quality, we found in children and adolescents, strong evidence of a relationship between time spent in sedentary behavior and obesity. Moreover, moderate evidence was observed for blood pressure and total cholesterol, self-esteem, social behavior problems, physical fitness and academic achievement. In adults, we found strong evidence of a relationship between sedentary behavior and all-cause mortality, fatal and non-fatal cardiovascular disease, type 2 diabetes and metabolic syndrome. In addition, there is moderate evidence for incidence rates of ovarian, colon and endometrial cancers.This overview based on the best available systematics reviews, shows that sedentary behavior may be an important determinant of health, independently of physical activity. However, the relationship is complex because it depends on the type of sedentary behavior and the age group studied. The relationship between sedentary behavior and many health outcomes remains uncertain; thus, further studies are warranted.

    Strech, Daniel; Sofaer, Neema

    2012-02-01

    Systematic reviews, which were developed to improve policy-making and clinical decision-making, answer an empirical question based on a minimally biased appraisal of all the relevant empirical studies. A model is presented here for writing systematic reviews of argument-based literature: literature that uses arguments to address conceptual questions, such as whether abortion is morally permissible or whether research participants should be legally entitled to compensation for sustaining research-related injury. Such reviews aim to improve ethically relevant decisions in healthcare, research or policy. They are better tools than informal reviews or samples of literature with respect to the identification of the reasons relevant to a conceptual question, and they enable the setting of agendas for conceptual and empirical research necessary for sound policy-making. This model comprises prescriptions for writing the systematic review's review question and eligibility criteria, the identification of the relevant literature, the type of data to extract on reasons and publications, and the derivation and presentation of results. This paper explains how to adapt the model to the review question, literature reviewed and intended readers, who may be decision-makers or academics. Obstacles to the model's application are described and addressed, and limitations of the model are identified.

    AIM To determine the prevalence and incidence ofdiabetic nephropathy in Africa.METHODS: We performed a systematic narrativereview of published literature following the MOOSEGuidelines for Meta-Analysis and Systematic Reviewsof Observational Studies. We searched PubMed-MEDLINE for all articles published in English and Frenchlanguages between January 1994 and July 2014 usinga predefined strategy based on the combination ofrelevant terms and the names of each of the 54 Africancountries and African sub-regions to capture the largestnumber of studies, and hand-searched the referencelists of retrieved articles. Included studies reported onthe prevalence, incidence or determinants of chronickidney disease (CKD) in people with diabetes withinAfrican countries.RESULTS: Overall, we included 32 studies from 16countries; two being population-based studies andthe remaining being clinic-based surveys. Most of thestudies (90.6%) were conducted in urban settings.Methods for assessing and classifying CKD variedwidely. Measurement of urine protein was the mostcommon method of assessing kidney damage (62.5%of studies). The overall prevalence of CKD varied from11% to 83.7%. Incident event rates were 94.9% forproteinuria at 10 years of follow-up, 34.7% for endstagerenal disease at 5 years of follow-up and 18.4%for mortality from nephropathy at 20 years of followup.Duration of diabetes, blood pressure, advancingage, obesity and glucose control were the commondeterminants of kidney disease.CONCLUSION: The burden of CKD is importantamong people with diabetes in Africa. High quality datafrom large population-based studies with validatedmeasures of kidney function are still needed to bettercapture the magnitude and characteristics of diabeticnephropathy in Africa.

    The purpose of this study was to perform a systematic review to assess the short-, middle- and long-term consequences of sarcopenia. Prospective studies assessing the consequences of sarcopenia were searched across different electronic databases (MEDLINE, EMBASE, EBM Reviews, Cochrane Database of Systematic Reviews, EBM Reviews ACP Journal Club, EBM Reviews DARE and AMED). Only studies that used the definition of the European Working Group on Sarcopenia in Older People to diagnose sarcopenia were included. Study selection and data extraction were performed by two independent reviewers. For outcomes reported by three or more studies, a meta-analysis was performed. The study results are expressed as odds ratios (OR) with 95% CI. Of the 772 references identified through the database search, 17 were included in this systematic review. The number of participants in the included studies ranged from 99 to 6658, and the duration of follow-up varied from 3 months to 9.8 years. Eleven out of 12 studies assessed the impact of sarcopenia on mortality. The results showed a higher rate of mortality among sarcopenic subjects (pooled OR of 3.596 (95% CI 2.96-4.37)). The effect was higher in people aged 79 years or older compared with younger subjects (p = 0.02). Sarcopenia is also associated with functional decline (pooled OR of 6 studies 3.03 (95% CI 1.80-5.12)), a higher rate of falls (2/2 studies found a significant association) and a higher incidence of hospitalizations (1/1 study). The impact of sarcopenia on the incidence of fractures and the length of hospital stay was less clear (only 1/2 studies showed an association for both outcomes). Sarcopenia is associated with several harmful outcomes, making this geriatric syndrome a real public health burden.

    2011-02-01

    In this systematic review, we present a comprehensive and up-to-date systematic review of the literature as it relates to the efficacy and effectiveness of spinal manipulation or mobilization in the management of cervical, thoracic, and lumbar-related extremity pain. There is moderate quality evidence that spinal manipulation is effective for the treatment of acute lumbar radiculopathy. The quality of evidence for chronic lumbar spine-related extremity symptoms and cervical spine-related extremity symptoms of any duration is low or very low. At present, no evidence exists for the treatment of thoracic radiculopathy. Future high-quality studies should address these conditions.

    Context: Barriers to the use of systematic reviews by policymakers may be overcome by resources that adapt and present the findings in formats more directly tailored to their needs. We performed a systematic scoping review to identify such knowledge-translation resources and evaluations of them. Methods: Resources were eligible for inclusion in this study if they were based exclusively or primarily on systematic reviews and were aimed at health care policymakers at the national or local level. Resources were identified by screening the websites of health technology assessment agencies and systematic review producers, supplemented by an email survey. Electronic databases and proceedings of the Cochrane Colloquium and HTA International were searched as well for published and unpublished evaluations of knowledge-translation resources. Resources were classified as summaries, overviews, or policy briefs using a previously published classification. Findings: Twenty knowledge-translation resources were identified, of which eleven were classified as summaries, six as overviews, and three as policy briefs. Resources added value to systematic reviews by, for example, evaluating their methodological quality or assessing the reliability of their conclusions or their generalizability to particular settings. The literature search found four published evaluation studies of knowledge-translation resources, and the screening of abstracts and contact with authors found three more unpublished studies. The majority of studies reported on the perceived usefulness of the service, although there were some examples of review-based resources being used to assist actual decision making. Conclusions: Systematic review producers provide a variety of resources to help policymakers, of which focused summaries are the most common. More evaluations of these resources are required to ensure users’ needs are being met, to demonstrate their impact, and to justify their funding. PMID:21418315

    The knowledge of reporting compliance of systematic reviews with PRISMA guidelines may assist in improving the quality of secondary research in brain AVM management and subsequently application to patient population and clinical practice. This may allow researchers and clinicians to be equipped to appraise existing literatures based on known deficit to look for or expect. The objective of this study was to assess the compliance of systematic reviews and meta-analysis in the management of brain AVM. Systematic reviews and meta-analyses articles published in medical journals between 1st of May 2011 and 30th April 2016 (five-year period) were examined. Exclusion criteria were articles that were not systematic reviews and not meta-analyses, narrative literature reviews, historical literature reviews, animal studies, unpublished articles, commentaries and letter to the editor. Electronic database search performed through Medline PubMed on 20th September 2016. This systematic review examined seven systematic review articles on intracranial arteriovenous malformation compliance with PRISMA statement guidelines. The mean percentage of applicable PRISMA items across all studies was 74% (range 67-93%). Protocol registration and declaration, risk of bias and funding sources were the most poorly reported of the PRISMA items (14% each). A significant variance in the total percentages was evident between studies (67-93%). Systematic review reporting in medical literature is excessively variable and overall poor. As these papers are being published with increasing frequency, need to fully adhere to PRISMA statement guide for systematic review to ensure high-quality publications. Complete reporting of PRISMA items within systematic reviews in cerebral arteriovenous malformation enhance quality assessment, robust critical appraisal, better judgement and ultimately sound application to practice thereby improving research standards and patients care.

    Surgical treatment of odontoid fractures is recommended by many surgeons to prevent sudden neurologic injury or progressive myelopathy. Less aggressive approach to the treatment of odontoid fractures has been advocated by some authors especially in the elderly population. Very few reports have followed up patients' outcomes following conservative treatment of odontoid fractures. Here we evaluate the clinical and radiographic results of patients without myelopathy treated without surgery for an odontoid type fracture. 101 patients with traumatic odontoid fracture admitted to the Pennsylvania State Hershey Medical Center between 1998 and 2008. Fractures were defined using a CT scan according to the Anderson-D'Alonzo Classification. Conservative treatment was pursued in appropriately selected patients. Fifty-nine patients were selected to be treated in a cervical collar. Sixteen patients failed using radiographic evidence and continued neck pain. Fourteen patients went on to be surgically stabilized. The other two patients opted to continue with cervical orthosis and regular clinical evaluations. The Forty-three remaining patients had stable imaging studies and with no other complaints. None of the patients developed myelopathy symptoms during the follow-up period. Our results indicate that a select group of patients with odontoid fracture who are deemed stable on initial evaluation in a cervical orthosis may be effectively managed non-operatively. None of the patients who were managed conservatively had clinical worsening during the period of management. The decision to proceed with surgical treatment was based on failure of resolution of neck pain or worsening or concerning instability on imaging studies. However in many patients, even elderly patients in a surgical risks are greater, many odontoid fractures can be safely managed in a cervical orthosis. Copyright © 2013 Elsevier B.V.

    Full Text Available Saravana Kumar,1 Kate Beaton,1 Tricia Hughes2 1International Centre for Allied Health Evidence, School of Health Sciences, University of South Australia, Adelaide, South Australia, Australia; 2Australian Association of Massage Therapists, Adelaide, South Australia, Australia Introduction: The last decade has seen a growth in the utilization of complementary and alternative medicine therapies, and one of the most popular and sought-after complementary and alternative medicine therapies for nonspecific low back pain is massage. Massage may often be perceived as a safe therapeutic modality without any significant risks or side effects. However, despite its popularity, there continues to be ongoing debate on the effectiveness of massage in treating nonspecific low back pain. With a rapidly evolving research evidence base and access to innovative means of synthesizing evidence, it is time to reinvestigate this issue. Methods: A systematic, step-by-step approach, underpinned by best practice in reviewing the literature, was utilized as part of the methodology of this umbrella review. A systematic search was conducted in the following databases: Embase, MEDLINE, AMED, ICONDA, Academic Search Premier, Australia/New Zealand Reference Centre, CINAHL, HealthSource, SPORTDiscus, PubMed, The Cochrane Library, Scopus, Web of Knowledge/Web of Science, PsycINFO, and ProQuest Nursing and Allied Health Source, investigating systematic reviews and meta-analyses from January 2000 to December 2012, and restricted to English-language documents. Methodological quality of included reviews was undertaken using the Centre for Evidence Based Medicine critical appraisal tool. Results: Nine systematic reviews were found. The methodological quality of the systematic reviews varied (from poor to excellent although, overall, the primary research informing these systematic reviews was generally considered to be weak quality. The findings indicate that massage may be an

    BACKGROUND: Acupuncture has been used as a treatment for cognitive impairment.OBJECTIVE: This review assesses clinical evidence for or against acupuncture as a treatment for cognitive impairment. This review also discusses the proposed mechanism(s) that could link acupuncture to improved cognitive function.RESULTS: Twelve studies met the inclusion criteria: 3 human studies and 9 animal studies. Levels of evidence ranged from level 1b to level 5.CONCLUSION: Most animal studies demonstrated a positive effect of acupuncture on cognitive impairment. However, the results of human studies were inconsistent. Further high-quality human studies with greater statistical power are needed to determine the effectiveness of acupuncture and an optimal protocol.

The aim of this review article is to compare oncologic adequacy and safety of LG with open surgery for gastric adenocarcinomas with respect to lymphadenectomy, short-term outcomes (postoperative morbidity and mortality and long-term outcome (5 years overall survival and disease-free survival. Materials and Methods: PubMed was searched using query “LG” for literature published in English from January 2000 to April 2014. A total of 875 entries were retrieved. These articles were screened and 59 manuscripts ultimately formed the basis of current review. Results: There is high-quality evidence to support short-term efficacy, safety and feasibility of LG for gastric adenocarcinomas, although accounts on long-term survivals are still infrequent.

  17. Effectiveness of Occupational Therapy Interventions for Lower-Extremity Musculoskeletal Disorders: A Systematic Review.

    Science.gov (United States)

    Dorsey, Julie; Bradshaw, Michelle

    Lower-extremity (LE) musculoskeletal disorders (MSDs) can have a major impact on the ability to carry out daily activities. The effectiveness of interventions must be examined to enable occupational therapy practitioners to deliver the most appropriate services. This systematic review examined the literature published between 1995 and July 2014 that investigated the effectiveness of occupational therapy interventions for LE MSDs. Forty-three articles met the criteria and were reviewed. Occupational therapy interventions varied on the basis of population subgroup: hip fracture, LE joint replacement, LE amputation or limb loss, and nonsurgical osteoarthritis and pain. The results indicate an overall strong role for occupational therapy in treating clients with LE MSDs. Activity pacing is an effective intervention for nonsurgical LE MSDs, and multidisciplinary rehabilitation is effective for LE joint replacement and amputation. Further research on specific occupational therapy interventions in this important area is needed. Copyright © 2017 by the American Occupational Therapy Association, Inc.

    Few women in industrialized countries achieve the World Health Organization's recommendation to breastfeed exclusively for 6 months. Governments are increasingly seeking new interventions to address this problem, including the use of incentives. The goal of this study was to assess the evidence regarding the effectiveness of incentive interventions, delivered within or outside of health care settings, to individuals and/or their families seeking to increase and sustain breastfeeding in the first 6 months after birth. Searches of electronic databases, reference lists, and grey literature were conducted to identify relevant reports of published, unpublished, and ongoing studies. All study designs published in English, which met our definition of incentives and that were from a developed country, were eligible for inclusion. Abstract and full-text article review with sequential data extraction were conducted by 2 independent authors. Sixteen full reports were included in the review. The majority evaluated multicomponent interventions of varying frequency, intensity, and duration. Incentives involved providing access to breast pumps, gifts, vouchers, money, food packages, and help with household tasks, but little consensus in findings was revealed. The lack of high-quality, randomized controlled trials identified by this review and the multicomponent nature of the interventions prohibited meta-analysis. This review found that the overall effect of providing incentives for breastfeeding compared with no incentives is unclear due to study heterogeneity and the variation in study quality. Further evidence on breastfeeding incentives offered to women is required to understand the possible effects of these interventions. Copyright © 2015 by the American Academy of Pediatrics.

  1. Management of tripod fractures (zygomaticomaxillary complex 1 point and 2 point fixations: A 5-year review

    Directory of Open Access Journals (Sweden)

    K Balakrishnan

    2015-01-01

    Full Text Available The zygomaticomaxillary complex (ZMC plays a key role in the structure, function, and esthetic appearance of the facial skeleton. They can account for approximately 40% of mid-face fractures. They are the second most common facial bone fracture after nasal bone injuries. The fracture complex results from a direct blow to the malar eminence and results in three distinct fracture components that disrupt the anchoring of the zygoma. In addition, the fracture components may result in impingement of the temporalis muscle, trismus (difficulty with mastication and may compromise the infraorbital foramen/nerve resulting in hypesthesia within its sensory distribution. A 4-year retrospective review of all patients treated with ZMC fractures at oral and maxillofacial surgery department, sree balaji dental college and hospital was performed. Computed tomography scans were reviewed. Demographics, treatment protocols, outcomes, complications, reoperations, and length of follow-up were identified. A total of 245 patients was identified by the Current Procedural Terminology codes for ZMC fractures. Closed or open reduction methods were performed with the goal of treatment being preservation of normal facial structure, sensory function, globe position, and mastication functionality. Unacceptably poor surgical outcomes are uncommon. Significant facial asymmetry requiring surgical revision occurs in 3-4% of patients. Postoperative infection rates are extremely low, and these infections nearly always resolve with oral antibiotics. In general, the long-term prognosis after repair of ZMC fractures is very good.

    2017-01-01

    Full Text Available Purpose of Review: Gossypibomas remain a dreaded and unwanted complication of surgical practice. Despite significant interest and numerous guidelines, the number of reported cases remains sparse due to various factors, including potential legal implications. Herein, we review related data from India to ascertain if the problem is better or worse than that reported in world literature. Materials and Methods: A literature search was performed on PubMed and Google Scholar, to collect and analyze all case reports and case reviews regarding the condition in India. Results: On analysis of the results, there were 100 publications reporting a total of 126 events. The average patient age was 38.65 years. Average time to discovery was 1225.62 days. Forty-nine percent of reported cases were discovered within the 1 st year. The most common clinical features were pain (73.8%, palpable mass (47.6%, vomiting (35%, abdominal distention (26%, and fever (12.6%. Spontaneous expulsion of the gossypiboma was noted in five cases (3.96%. Transmural migration was seen in 36 cases (28.57%. Conclusions: Despite advancements in surgical approaches and preventive measures, gossypibomas continue to be a cause of significant morbidity. A safe working culture, open communication, teamwork, and an accurate sponge count remain our best defence against this often unpredictable complication of surgery.

    2017-07-01

    Despite the increasing awareness of scientific fraud, no attempt has been made to assess its prevalence in neurosurgery. The aim of our review was to assess the chronologic trend, reasons, research type/design, and country of origin of retracted neurosurgical publications. Three independent reviewers searched the EMBASE and MEDLINE databases using neurosurgical keywords for retracted articles from 1995 to 2016. Archives of retracted articles (retractionwatch.com) and the independent Web sites of neurosurgical journals were also searched. Data including the journal, impact factor, reason for retraction, country of origin, and citations were extracted. A total of 97 studies were included for data extraction. Journal impact factor ranged from 0.57 to 35.03. Most studies (61) were retracted within the last 5 years. The most common reason for retraction was because of a duplicated publication found elsewhere (26), followed closely by plagiarism (22), or presenting fraudulent data (14). Other reasons included scientific errors/mistakes, author misattribution, and compromised peer review. Articles originated from several countries and some were widely cited. Retractions of neurosurgical publications are increasing significantly, mostly because of issues of academic integrity, including duplicate publishing and plagiarism. Implementation of more transparent data-sharing repositories and thorough screening of data before manuscript submission, as well as additional educational programs for new researchers, may help mitigate these issues in the future.

    This paper presents a critical review of literature on fracture analysis of concrete structural components. Review includes various fracture models, tension softening models, methodologies for crack growth analysis and remaining life prediction. The widely used fracture models which are based on fictitious crack approach and effective elastic crack approach have been explained. Various tension softening models such as linear, bi-linear, tri-linear, etc. have been presented with appropriate expressions. From the critical review of models, it has been observed that some of the models have complex expressions involving many parameters. There is a need to develop some more generalised models. Studies have been conducted on crack growth analysis and remaining life prediction using linear elastic fracture mechanics (LEFM) principles. From the studies, it has been observed that there is significant difference between predicted and experimental observations. The difference in the values is attributed to not considering the tension softening effect in the analysis.

    Currently available treatment options for melasma include prevention of UV radiation, topical lightening agents, chemical peels, and light-based and laser therapies. However, none have shown effective and sustained results, with incomplete clearance and frequent recurrences. There has been increasing interest recently in oral medications and dietary supplements in improving melasma. We sought to evaluate the efficacy and safety/tolerability of oral medications and dietary supplements for the treatment of melasma. Multiple databases were systematically searched for randomized clinical trials (RCTs) evaluating the use of oral medication for treatment of melasma alone or in combination with other treatments. A total of eight RCTs met inclusion criteria. Oral medications and dietary supplements evaluated include tranexamic acid, Polypodium leucotomos extract, beta-carotenoid, melatonin, and procyanidin. These agents appear to have a beneficial effect on melasma improvement. In conclusion, oral medications have a role in melasma treatment and have been shown to be efficacious and tolerable with a minimal number and severity of adverse events. Therefore, dermatologists should keep oral medications and dietary supplements in their armamentarium for the treatment of melasma.

    Hypertension and insomnia are very common and often coexist. There is evidence to suggest that the increasing prevalence of arterial hypertension in the past decade might be related both to an increased prevalence of insomnia and to the decline of sleep duration due to modern lifestyle. The aim of this paper is to reconsider both the clinical evidence of the relationship between conditions of sleep loss and of perceived impairment in sleep quality with hypertension and the potential pathophysiological mechanisms underlying the biological plausibility of their relationship. Through a systematic search from MEDLINE, EMBASE, PsychINFO we selected articles, which reported experimental sleep deprivation designs, or studied sleep duration or insomnia and their relationship with blood pressure or hypertension in participants over 18 years. This analysis shows that experimental sleep deprivation, short sleep duration, and persistent insomnia are associated with increased blood pressure and increased risk of hypertension, even after controlling for other risk factors. Pathophysiological mechanisms underlying this association might be related to inappropriate arousal ("hyperarousal") due to an overactivation of stress system functions. According this hypothesis, prolonged sleep loss or alterations of sleep quality might act as a neurobiological and physiologic stressor that impair brain functions and contribute to allostatic load, compromising stress resilience and somatic health.

    The present report provides an overview of terminology studies in audiology including topics and study characteristics, as well as categorizing the main issues. The goals are to improve the understanding of the current issues for terminology in audiology and to provide some basic information that will be useful to develop an international standard. Search procedures were completed over two phases. Phase 1 included a systematic electronic searches using MEDLINE (PubMed), Excerpta Medica Database, Cumulative Index to Nursing and Allied Health Literature, and International Organization for Standardization with keywords related to terminology of audiology. The studies were initially identified according to the titles of 2921 publications following careful abstract examination. Of these, whole texts of 16 publications were retrieved. Five papers met the inclusion criteria were further investigated. In phase 2, a manual search was conducted to collect additional publications with keywords related to terminology project in audiology. A total of 16 papers were found. The essential terminology issues classified included 'appropriateness,' 'classification/framework,' 'inconsistency of terminology,' 'multilingual and international aspects,' and 'service quality/delivery including communication and accessibility.' This was indicative of the paucity of terminology research in audiology, despite recurring terminology issues. Establishment of standardized terminology in audiology may minimize current challenging terminology issues by improving appropriateness and consistency of terminology as well as communication among relevant stakeholders at national and international levels.

    Best practices in HIV care have the potential to improve patient outcomes and inform practice. We conducted a systematic review of best practices in HIV care that were published from 2003 to 2013. Practices that demonstrated success in achieving desired results based on their objectives were included in the review. Two themes emerged from the eight articles reviewed: (a) the importance of linking newly diagnosed people living with HIV to care and (b) the role of integrated and comprehensive service provision in improving patient outcomes. Inconsistencies in reporting and arbitrary use of the term "best practices" were hurdles in this review.

    Full Text Available Objective: The goal of this systematic review was to examine the reporting quality of the method section of quantitative systematic reviews and meta-analyses from 2009 to 2016 in the field of industrial and organizational psychology with the help of the Meta-Analysis Reporting Standards (MARS, and to update previous research, such as the study of Aytug et al. (2012 and Dieckmann et al. (2009.Methods: A systematic search for quantitative systematic reviews and meta-analyses was conducted in the top 10 journals in the field of industrial and organizational psychology between January 2009 and April 2016. Data were extracted on study characteristics and items of the method section of MARS. A cross-classified multilevel model was analyzed, to test whether publication year and journal impact factor (JIF were associated with the reporting quality scores of articles.Results: Compliance with MARS in the method section was generally inadequate in the random sample of 120 articles. Variation existed in the reporting of items. There were no significant effects of publication year and journal impact factor (JIF on the reporting quality scores of articles.Conclusions: The reporting quality in the method section of systematic reviews and meta-analyses was still insufficient, therefore we recommend researchers to improve the reporting in their articles by using reporting standards like MARS.

    Full Text Available Along with a growing elderly population in the world and in our country, elder abuse and neglect has been a major problem. The purpose of this study is to identify and systematically review the studies investigating elder abuse and neglect in Turkey. Evaluation of the studies on elder abuse and neglect in Turkey showed that the elderly are often abused by family members and they are often exposed to emotional, physical, economic and psychological abuse. All of the studies reviewed in this paper were descriptive cross-sectional studies investigating elder abuse and neglect. The studies reviewed presented significant results revealing the prevalence of elder abuse and neglect in Turkey. In conclusion, this systematic review revealed that research on this issue in Turkey is insufficient and there is a need for studies conducted with larger samples covering an entire city.

    With the increase in the number of systematic reviews available, a logical next step to provide decision makers in healthcare with the evidence they require has been the conduct of reviews of existing systematic reviews. Syntheses of existing systematic reviews are referred to by many different names, one of which is an umbrella review. An umbrella review allows the findings of reviews relevant to a review question to be compared and contrasted. An umbrella review's most characteristic feature is that this type of evidence synthesis only considers for inclusion the highest level of evidence, namely other systematic reviews and meta-analyses. A methodology working group was formed by the Joanna Briggs Institute to develop methodological guidance for the conduct of an umbrella review, including diverse types of evidence, both quantitative and qualitative. The aim of this study is to describe the development and guidance for the conduct of an umbrella review. Discussion and testing of the elements of methods for the conduct of an umbrella review were held over a 6-month period by members of a methodology working group. The working group comprised six participants who corresponded via teleconference, e-mail and face-to-face meeting during this development period. In October 2013, the methodology was presented in a workshop at the Joanna Briggs Institute Convention. Workshop participants, review authors and methodologists provided further testing, critique and feedback on the proposed methodology. This study describes the methodology and methods developed for the conduct of an umbrella review that includes published systematic reviews and meta-analyses as the analytical unit of the review. Details are provided regarding the essential elements of an umbrella review, including presentation of the review question in a Population, Intervention, Comparator, Outcome format, nuances of the inclusion criteria and search strategy.

    Given recent, rapid growth in the field of women veterans' mental health, the goal of this review was to update the status of women veterans' mental health research and to identify current themes in this literature. The scope of this review included women veterans' unique mental health needs, as well as gender differences in veterans' mental health needs. Database searches were conducted for relevant articles published between January 2008 and July 2011. Searches were supplemented with bibliographic reviews and consultation with subject matter experts. The database search yielded 375 titles; 32 met inclusion/exclusion criteria. The women veterans' mental health literature crosses over several domains, including prevalence, risk factors, health care utilization, treatment preferences, and access barriers. Studies were generally cross-sectional, descriptive, mixed-gender, and examined Department of Veterans Affairs (VA) health care users from all service eras. Results indicate higher rates of specific disorders (e.g., depression) and comorbidities, with differing risk factors and associated medical and functional impairment for female compared with male veterans. Although satisfaction with VA health care is generally high, unique barriers to care and indices of treatment satisfaction exist for women. There is a breadth of descriptive knowledge in many content areas of women veterans' mental health; however, the research base examining interventional and longitudinal designs is less developed. Understudied content areas and targets for future research and development include certain psychiatric disorders (e.g., schizophrenia), the effects of deployment on woman veterans' families, and strategies to address treatment access, attrition, and provision of gender-sensitive care.

    Violence, experienced in either childhood or adulthood, has been associated with physical health outcomes, including cardiovascular disease. However, the consistency of the existing literature has not been evaluated. In 2013, the authors conducted a PubMed and Web of Science review of peer-reviewed articles published prior to August 2013 on the relation between violence exposure, experienced in either childhood or adulthood, and cardiovascular outcomes. To meet inclusion criteria, articles had to present estimates for the relation between violence exposure and cardiovascular outcomes (e.g., hypertension, blood pressure, stroke, coronary disease, or myocardial infarction) adjusted for demographic factors. Articles focusing on violence from television, video games, natural disasters, terrorism, or war were excluded. The initial search yielded 2,273 articles; after removing duplicates and applying inclusion and exclusion criteria, 30 articles were selected for review. A consistent positive relation was noted on the association between violence experienced during childhood and cardiovascular outcomes in adulthood (i.e., hypertension, coronary heart disease, and myocardial infarction). Associations across genders with varying types of violence exposure were also noted. By contrast, findings were mixed on the relation between adult violence exposure and cardiovascular outcome. Despite varying definitions of violence exposure and cardiovascular endpoints, a consistent relation exists between childhood violence exposure, largely assessed retrospectively, and cardiovascular endpoints. Findings are mixed for the adult violence-cardiovascular health relation. The cross-sectional nature of most adult studies and the reliance of self-reported outcomes can potentially be attributed to the lack of findings among adult violence exposure studies.

    Performing a peer review of an article under consideration for publication requires not only an understanding of the subject matter, but also a systematic approach that includes screening for conflicts of interest; determining whether the manuscript is within or outside the reviewer's area of expertise; properly classifying the manuscript; and writing a detailed, organized review. Although some journals may provide guidelines for the reviewers, the guidelines usually are not detailed and do not take into consideration the variability in reviewer experience. This article is meant to serve as a guideline for peer reviewers and provide concrete information on how to write a comprehensive, unbiased review that will serve both the author and the journal well.

    Full Text Available Objective. To investigate the efficacy of antioxidants for preventing preeclampsia and other maternal and fetal complications among pregnant women with low, moderate, or high risk of preeclampsia. Methods. We searched MEDLINE, Embase, CENTRAL, mRCT, and other databases, with no language or publication restrictions. Two independent reviewers selected randomized controlled trials that evaluated the use of antioxidants versus placebo and extracted the relevant data. Relative risks (RRs and 95% confidence intervals (95% CIs were calculated. The data were compiled through the random effects model. Main Results. Fifteen studies were included (21,012 women and 21,647 fetuses. No statistically significant difference was found between women who received antioxidant treatment and women who received placebo for preeclampsia (RR =0.92; 95% CI: 0.82–1.04, severe preeclampsia (RR =1.03; 95% CI: 0.87–1.22, preterm birth (RR =1.03; 95% CI: 0.94–1.14, and small for gestational age <10th centile (RR =0.92; 95% CI: 0.80–1.05. Side effects were numerically more frequent in the antioxidants group compared to placebo, but without significant statistical difference (RR =1.24; 95% CI: 0.85–1.80. Conclusions. The available evidence reviewed does not support the use of antioxidants during pregnancy for the prevention of preeclampsia and other outcomes.

    2017-09-26

    Currently available techniques for the evaluation of small fiber neuropathy and related sudomotor function remain suboptimal. Electrochemical skin conductance (ESC) has recently been introduced as a simple noninvasive and fast method for the detection of sudomotor dysfunction. The purpose of this review is to synthesize and appraise research using ESC measurements for sudomotor evaluation in adults. Electronic databases including MEDLINE and Google Scholar were searched (up to March 13, 2017). The search strategy included the following terms: "electrochemical skin conductance," "Sudoscan," and "EZSCAN." Evidence was graded according to defined quality indicators including (1) level of evidence; (2) use of established tests as reference tests (e.g., quantitative sudomotor axon test [QSART], sympathetic skin responses [SSR], thermoregulatory sweat test [TST], and skin biopsies to assess sudomotor and epidermal small fibers); (3) use of consecutive/non-consecutive subjects; and (4) study design (prospective/retrospective). A total of 24 studies met the inclusion criteria. These were classified into preclinical, normative, comparative/diagnostic, or interventional. ESC measurement properties, diagnostic accuracy, and similarities to and differences from established tests were examined. ESC measurements expand the arsenal of available tests for the evaluation of sudomotor dysfunction. The advantages and disadvantages of ESC versus established tests for evaluating sudomotor/small fiber function reviewed herein should be used as evidence to inform future guidelines on the assessment of sudomotor function.

    2017-08-01

    This integrative review describes the genomic variants that have been found to be associated with poor prognosis in patients diagnosed with multiple myeloma (MM). Second, it identifies MM genetic and genomic changes using next-generation sequencing, specifically whole-genome sequencing or exome sequencing. A search for peer-reviewed articles through PubMed, EBSCOhost, and DePaul WorldCat Libraries Worldwide yielded 33 articles that were included in the final analysis. The most commonly reported genetic changes were KRAS, NRAS, TP53, FAM46C, BRAF, DIS3, ATM, and CCND1. These genetic changes play a role in the pathogenesis of MM, prognostication, and therapeutic targets for novel therapies. MM genetics and genomics are expanding rapidly; oncology nurse clinicians must have basic competencies in genetics and genomics to help patients understand the complexities of genetic and genomic alterations and be able to refer patients to appropriate genomic professionals if needed.

    The distal radius fractures (DRFs) are the second most common fracture in the elderly population. Despite their frequency, the optimal treatment of these fractures remains controversial. Several dogmatic myths on DRFs management may adversely affect their outcome and despite a strong trend versus surgical options, systematic reviews suggest that conservative treatment remains the safest option for DRFs in most cases.

    2017-10-04

    This review focuses on the use of peripheral nerve blocks as preoperative analgesia, as postoperative analgesia, or as a supplement to general anesthesia for hip fracture surgery and tries to determine if they offer any benefit in terms of pain on movement at 30 minutes after block placement, acute confusional state, myocardial infarction/ischemia, pneumonia, mortality, time to first mobilization, and cost of analgesic. Trials were identified by computerized searches of Cochrane Central Register of Controlled Trials (2016, Issue 8), MEDLINE (Ovid SP, 1966 to 2016 August week 1), Embase (Ovid SP, 1988 to 2016 August week 1), and the Cumulative Index to Nursing and Allied Health Literature (EBSCO, 1982 to 2016 August week 1), trials registers, and reference lists of relevant articles. Randomized controlled trials involving the use of nerve blocks as part of the care for hip fractures in adults aged 16 years and older were included. The quality of the studies was rated according to the Cochrane tool. Two authors independently extracted the data. The quality of evidence was judged according to the Grading of Recommendations, Assessment, Development, and Evaluations Working Group scale. Based on 8 trials with 373 participants, peripheral nerve blocks reduced pain on movement within 30 minutes of block placement: standardized mean difference, -1.41 (95% confidence interval [
