    2014-11-01

    Full Text Available Globally, virtual teams (VT as ICT-enabled emergent network organisation forms have gained international validity by innovative organisations, with a corresponding surge of interest in understanding how organisations can leverage VT to create business value. Despite growing deliberations in VT literature on managing VT, tasks and outcomes, however, creating business value through VT remains an unresolved theoretical and pragmatic conundrum. A review of prior relevant literature is essential to advancing knowledge. The paucity of published review articles seems to have impeded the field’s accumulation of VT knowledge. This research, therefore, reviews the current literature on case studies of VT to address the question: What are organisational challenges in creating business value through VT in the organisation? The key challenges found in the literature are effective communication, knowledge sharing, trust, and interpersonal skills in the new virtual boundary-less environment. Drawing on the IT business value model, we also discuss their resource-based implications.

    The purpose of this review is to examine the current literature regarding calcium and Vitamin D deficiencies in vegan diets and the possible relationship to low bone mineral density and incidence for fracture. Prominent databases were searched for original research publications providing data capable of answering these questions: (i) Do vegans have lower-than-recommended levels of calcium/Vitamin D? (ii) Do vegans have lower bone mineral density than their non-vegan counterparts? (iii) Are vegans at a greater risk for fractures than non-vegans? The findings gathered consistently support the hypothesis that vegans do have lower bone mineral density than their non-vegan counterparts. However, the evidence regarding calcium, Vitamin D and fracture incidence is inconclusive. More research is needed to definitively answer these questions and to address the effects of such deficiencies on the medical and socioeconomic aspects of life.

    This study aimed to provide an overview of the literature on buccal mucosal ureteroplasty for ureteral stricture disease, with a specific focus on the application of the robotic platform to buccal ureteroplasty. In our review, we highlight the results of Zhao et al. from the New York University School of Medicine Department of Urology, as well as our own results from Temple University Hospital. Zhao et al. published the first series of four patients who underwent robotic buccal ureteroplasty. Mean stricture length was 3.0 cm, and at a mean follow-up of 15 months, all repairs remained patent. We also describe our results in 10 patients who underwent robotic buccal ureteroplasty at Temple University Hospital. Median stricture length was 3.0 cm, and at a median follow-up of 5 months, all repairs remain patent. Robotic buccal ureteroplasty offers a promising option for repair of complex ureteral strictures.

  7. Current aspects of polycystic ovary syndrome: A literature review

    Directory of Open Access Journals (Sweden)

    VICTOR HUGO LOPES DE ANDRADE

    Full Text Available SUMMARY Polycystic ovary syndrome (PCOS is a heterogeneous endocrine disorder with variable prevalence, affecting about one in every 15 women worldwide. The diagnosis of polycystic ovary syndrome requires at least two of the following criteria: oligoovulation and/or anovulation, clinical and/or biochemical evidence of hyperandrogenism and morphology of polycystic ovaries. Women with PCOS appear to have a higher risk of developing metabolic disorders, hypertension and cardiovascular disorders. The aim of this article was to present a review of the literature by searching the databases Pubmed and Scielo, focusing on publications related to polycystic ovaries, including its pathogenesis, clinical manifestations, diagnosis and therapeutic aspects, as well as its association with cardiovascular and arterial hypertensive disorders.

    Patellofemoral osteoarthritis (PFOA) can be associated with anterior knee pain, stiffness, and functional impairment. Some authors report that PFOA affects approximately 9% of patients older than 40 years with a greater prevalence in females. Etiology of PFOA is multifactorial and is related to the presence of abnormal stresses at the PF joint due to knee- and patient-related factors. The need for a joint preserving treatment by isolated replacement of the injured compartment of the knee led to the development of PF arthroplasty (PFA). When a correct PF replacement is performed, PFA preserves physiologic tibiofemoral joint, thus allowing patients for a rapid recovery with a high satisfaction. The outcomes for PFA are quite variable with a trend toward good to excellent results, mainly owing to the improvement in surgical techniques, patient selection, and implant design. The development of the second generation of PFA improved the outcomes, which is attributed to the different trochlear designs. Recently, encouraging results have been provided by the association of PFA and unicompartmental knee arthroplasty (UKA). In many studies, the main cause of PFA failure is progression of tibiofemoral OA. The aim of this brief review of literature is to summarize the clinical features, indications and contraindications, surgical techniques, complications, and outcomes of PFA. PMID:29270562

    Magnetic resonance neurography (also called MRN or MR neurography) refers to MR imaging dedicated to the peripheral nerves. It is a technique that enhances selective multiplanar visualisation of the peripheral nerve and pathology by encompassing a combination of two-dimensional, three-dimensional and diffusion imaging pulse sequences. Referring physicians who seek imaging techniques that can depict and diagnose peripheral nerve pathologies superior to conventional MR imaging are driving the demand for MRN. This article reviews the pathophysiology of peripheral nerves in common practice scenarios, technical considerations of MRN, current indications of MRN, normal and abnormal neuromuscular appearances, and imaging pitfalls. Finally, the emerging utility of diffusion-weighted and diffusion tensor imaging is discussed and future directions are highlighted. (orig.)

    Equestrian sports continue to grow in popularity in the Unites States and abroad, with an estimated 30 million people riding horses annually in the United States alone. Approximately one in five of these riders will suffer a serious injury during their riding career, requiring medical care and potentially hospitalization. Riding carries with it an implicit risk of injury associated with the unpredictability of the animals, the rider's head being positioned approximately 9 feet off the ground, and traveling unrestrained at speeds up to 40 mph. This article reviews common equestrian injuries, epidemiology, mechanism of injury, risk factors, and prevention strategies, with an emphasis on the more dangerous aspects of the sport.

    Vitamin D is associated with bone mineral density, and its deficiency is a global health problem. In psychiatry, low vitamin D levels have been associated with schizophrenia, depression, psychotic symptoms, and, more recently, alcohol use disorders. Alcohol use disorders are among the most prevalent mental disorders worldwide. Therefore, our aim was to evaluate the association between alcohol use and vitamin D serum levels. The PubMed, SCIELO, and Lilacs databases were searched for this systematic review. We assessed all articles published from 1976 to December 2015, and we examined the associated reference lists to retrieve articles that appeared to fulfill our criteria. Of 932 articles, 49 met our inclusion criteria. The majority of the papers (71.4%) were cross-sectional studies. Alcohol intake was found to be positively associated with vitamin D status in 15 articles and negatively associated with vitamin D in 18 articles; no association was found in 16 articles. Heterogeneous results were found in our review, with a similar number of papers indicating a positive association, a negative association or the absence of any association between alcohol use and vitamin D levels. Nevertheless, it is important to note that the studies in which a positive association was found were more recent papers that involved considerably larger sample sizes than those in other studies. The older studies compared vitamin D levels in alcoholic and non-alcoholic patients, in contrast to more recent studies, which focused on more specific populations. In addition, most of the selected papers were from high latitude countries, where exposure to sunlight tends to be lower than in tropical countries. The data concerning vitamin D levels in patients with alcohol use disorders remain controversial. Additional research using a standardized methodology is necessary to demonstrate the real impact of alcohol consumption on vitamin D serum levels as well as on the health status of alcohol users

    2018-04-01

    To compare the effectiveness of low-frequency pulsed current versus kilohertz-frequency alternating current in terms of evoked force, discomfort level, current intensity, and muscle fatigability; to discuss the physiological mechanisms of each neuromuscular electrical stimulation type; and to determine if kilohertz-frequency alternating current is better than low-frequency pulsed current for clinical treatment. Articles were obtained from PubMed, Scopus, Cochrane Central Register of Controlled Trials, CINAHL, MEDLINE, and SPORTSDiscus databases using the terms Russian current or kilohertz current or alternating current or pulsed current or Aussie current and torque or discomfort or fatigue or current intensity, and through citation tracking up to July 2017. Two independent reviewers selected studies comparing the use of the 2 neuromuscular electrical stimulation currents. Studies describing maximal current intensity tolerated and the main effects of the 2 different current types on discomfort, muscle force, and fatigability were independently reviewed. Data were systematized according to (1) methodology; (2) electrical current characteristics; and (3) outcomes on discomfort level, evoked force, current intensity, and muscle fatigability. The search revealed 15 articles comparing the 2 current types. Kilohertz-frequency alternated current generated equal or less force, similar discomfort, similar current intensity for maximal tolerated neuromuscular electrical stimulation, and more fatigue compared with low-frequency pulsed current. Similar submaximal levels of evoked force revealed higher discomfort and current intensity for kilohertz-frequency alternated current compared with low-frequency pulsed current. Available evidence does not support the idea that kilohertz-frequency alternated current is better than low-frequency pulsed current for strength training and rehabilitation.

    2018-01-01

    Management of menstruation in contexts of humanitarian emergencies can be challenging. A lack of empirical research about effective interventions which improve menstrual hygiene management (MHM) among female populations in humanitarian emergencies and a lack of clarity about which sectors within a humanitarian response should deliver MHM interventions can both be attributable to the lack of clear guidance on design and delivery of culturally appropriate MHM intervention in settings of humanitarian emergencies. The objective of this review was to collate, summarize, and appraise existing peer-reviewed and gray literature that describes the current scenario of MHM in emergency contexts in order to describe the breadth and depth of current policies, guidelines, empirical research, and humanitarian aid activities addressing populations' menstrual needs. A structured-search strategy was conducted for peer-reviewed and gray literature to identify studies, published reports, guidelines, and policy papers related to menstrual response in emergency humanitarian contexts. Of the 51 articles included in the review, 16 were peer-reviewed papers and 35 were gray literature. Most of the literature agreed that hardware interventions should focus on the supply of adequate material (not only absorbent material but also other supportive material) and adequate sanitation facilities, with access to water and private space for washing, changing, drying, and disposing menstrual materials. Software interventions should focus on education in the usage of materials to manage menstruation hygienically and education about the female body's biological processes. There was clear agreement that the needs of the target population should be assessed before designing any intervention. Although there is insight about which factors should be included in an effective menstrual hygiene intervention, there is insufficient empirical evidence to establish which interventions are most effective in

    To summarize the literature on cholesterol point-of-care tests (POCTs). This article would serve as a resource to assist community pharmacists in developing cholesterol point-of-care (POC) pharmacy services. A literature search was performed in MEDLINE Ovid, PubMed, EMBASE, and Cochrane database using the following medical subject headings (MeSH) terms: point-of-care test, cholesterol, blood chemical analysis, rapid testing, collaborative practice, community pharmacy, and ambulatory care. Additional resources including device manufacturer web sites were summarized to supplement the current literature. All human research articles, review articles, meta-analyses, and abstracts published in English through September 1, 2014, were considered. A total of 36 articles were applicable for review. Information was divided into the following categories to be summarized: devices, pharmacists' impact, and operational cost for the pharmacy. The current literature suggests that POCTs in community pharmacies assist with patient outcomes by providing screenings and referring patients with dyslipidemia for further evaluation. The majority of studies on cholesterol POC devices focused on accuracy, revealing the need for further studies to develop best practices and practice models with successful reimbursement. Accuracy, device specifications, required supplies, and patient preference should be considered when selecting a POC device for purchase.

    To visit the operative technique and to review the current published English literature on the technique, and outcomes following robot-assisted laparoscopic partial nephrectomy (RPN). We searched the published English literature and the PubMed(()) for published series of 'robotic partial nephrectomy' (RPN) using the keywords; robot, robot-assisted laparoscopic partial nephrectomy, laparoscopic partial nephrectomy, partial nephrectomy and laparoscopic surgery. The search yielded 15 major selected series of 'robotic partial nephrectomy'; these were reviewed, tracked and analysed in order to determine the current status and role of RPN in the management of early renal neoplasm(s), as a minimally invasive surgical alternative to open partial nephrectomy. A review of the initial peri-operative outcome of the 350 cases of select series of RPN reported in published English literature revealed a mean operating time, warm ischemia time, estimated blood loss and hospital stay, of 191 minutes, 25 minutes, 162 ml and 2.95 days, respectively. The overall computed mean complication rate of RPN in the present select series was about 7.4%. RPN is a safe, feasible and effective minimally invasive surgical alternative to laparoscopic partial nephrectomy for early stage (T(1)) renal neoplasm(s). It has acceptable initial renal functional outcomes without the increased risk of major complications in experienced hands. Prospective randomised, controlled, comparative clinical trials with laparoscopic partial nephrectomy (LPN) are the need of the day. While the initial oncological outcomes of RPN appear to be favourable, long-term data is awaited.

    Context: Motor impairments in individuals with autism spectrum disorder (ASD) have been frequently reported. In this review, we narrow our focus on postural control impairments to summarize current literature for patterns, underlying mechanisms, and determinants of posture in this population. Evidence Acquisition: A literature search was conducted through Medline, ISI web of Knowledge, Scopus and Google Scholar to include studies between 1992 and February 2013. Results: Individuals with ASD have problems in maintaining postural control in infancy that well persists into later years. However, the patterns and underlying mechanisms are still unclear. Conclusions: Examining postural control as an endophenotype or early diagnostic marker of autism is a conceptual premise which should be considered in future investigations. At the end of the review, methodological recommendations on the assessment of postural control have also been provided. PMID:25520765

    Advances in medical knowledge have contributed to the increase in the number of children living with some form of long-term chronic illness or condition. As a consequence of these advancements, treatments that are more accessible and easier to administer, usually within a child's home, have been developed. However, this may mean that parents take on greater treatment responsibility and require extra time and energy to meet these tasks, additional to other responsibilities. This review paper aims to summarize and critique existing literature on working parents of children with a chronic condition, by focusing on patterns of parent work, the challenges experienced, and the flow-on consequences to well-being. Employing a narrative, meta-synthesis of the current literature, this review identified 3 key themes related to working parents of children with chronic illness. The paper first identifies that although employment is less common, these parents are not necessarily nonworking. Second, these parents experience numerous challenges including balancing work and family, time constraints, stress, and feelings of "doing it all." And third, the above challenges lead to additional impacts on parental quality of life. This review summarizes what is currently known about work patterns, challenges, and consequences in parents of children with chronic conditions. Employment is clearly impacted for these parents. Although workplace challenges have been extensively researched, other challenges (eg, personal and family) and impacts on their well-being have not. This review discusses the present standing of this research. It outlines the strengths and limitations of the current literature, makes recommendations for future research, and suggests theoretical and practical implications of the further findings. © 2018 John Wiley & Sons Ltd.

    Full Text Available The impact of physical activity on human health has many benefits. Equally important in improving physical fitness and normalizing cardiovascular system seems to be the impact of exercise on mood of patients. Physical activity improves well-being, satisfaction and self-confidence. However, the condition of effective therapeutic intervention is due to its regularity, since only systematic exercises allow to maintain the beneficial effects of physical activity. Otherwise, the results achieved are only temporary. This article aims to review the current literature and show the most important aspects of motion therapy in improving the psychophysical condition of patients.

    To review the global select data on the current technique, perioperative outcome and literature on the robot-assisted pyeloplasty (RAP). The published English literature (PubMed) was extensively searched using the key words; robot, robot-assisted pyeloplasty, laparoscopy, laparoscopic pyeloplasty and ureteropelvic junction obstruction. The selected studies were then reviewed, tracked and analyzed in order to determine the current role, outcome and status of robot-assisted laparoscopic pyeloplasty. The search yielded about 25 published series on RAP comprising about 740 cases with a mean operative time, estimated blood loss, crossing vessel prevalence, hospital stay,perioperative complication rate and follow up duration of 194 min, 50 mL, 47%, 2.3 days, 6% and 14.9 months respectively. The initial peri-operative results and intermediate follow up of cases of repair of the ureteropelvic junction obstruction with robot-assisted pyeloplasty appear to be favorable and comparable to that of open pyeloplasty, while long term outcome data is still awaited. The da Vinci surgical robotic system is a promising surgical armamentarium in the hands of the modern day urologist for the minimally invasive definitive surgical management of both primary and secondary ureteropelvic junction obstruction.

    A newly-recommended method for restoring large cavities is the biomimetic approach of using short fiber-reinforced composite (SFRC) as dentine-replacing material. The aim of the current review was to present an overview of SFRC and to give the clinician a detailed understanding of this new material and treatment strategy based on available-literature review. A thorough literature search was done up to December 2017. The range of relevant publications was surveyed using PubMed and Google Scholar. From the search results, articles related to our search terms were only considered. The search terms used were "short fiber-reinforced composite", "everX posterior", and "fiber-reinforced composite restorations". Of the assessed articles selected (N = 70), most were laboratory-based research with various test specimen designs prepared according to the ISO standard or with extracted teeth; only four articles were clinical reports. A common finding was that by combining the SFRC as a bulk base with conventional composite, the load-bearing capacity and failure mode of the material combination were improved, as compared to plain conventional composite restoration. In the reviewed studies, the biomimetic restoration technique of using SFRC showed promising characteristics, and therefore, might be recommended as an alternative treatment option for large cavities. © 2018 John Wiley & Sons Australia, Ltd.

    No guidelines exist for the management of micropapillary bladder cancer (MPBC) and most reports of this variant of urothelial carcinoma are case series comprising small numbers of patients. We sought to determine current practice patterns for MPBC using a survey sent to the Society of Urologic Oncology (SUO) and to present those results in the setting of a comprehensive review of the existing literature. A survey developed by the Translational Science Working Group of the Bladder Cancer Advocacy Network-sponsored Think Tank meeting was distributed to members of the SUO. The results from 118 respondents were analyzed and presented with a literature review. Most survey respondents were urologists, with 80% considering bladder cancer their primary area of interest. Although 78% of the respondents reported a dedicated genitourinary pathologist at their institution, there were discrepant opinions on how a pathologic diagnosis of MPBC is determined as well as variability on the proportion of MPBC that is clinically significant. Among them, 78% treat MPBC differently than conventional urothelial carcinoma, with 81% reporting that they would treat cT1 MPBC with upfront radical cystectomy. However, the respondents had split opinions regarding the sensitivity of MPBC to cisplatin-based chemotherapy, which affected utilization of neoadjuvant chemotherapy in muscle-invasive disease.

    Science.gov (United States)

    2015-01-01

    Background: Medicinal marijuana has already been legalized in over 23 states with more considering legalization. Despite the trend toward legalization, to date, there has been no systematic review of the existing literature for the efficacy of medicinal marijuana for many of the conditions for which it is proposed to treat. This study seeks to understand the current literature regarding the use of medicinal marijuana in the treatment of posttraumatic stress disorder (PTSD). Data Sources: PubMed and PsycINFO databases were searched until April 2014 for articles outlining outcomes of case files, control studies, and observational studies regarding the efficacy of medicinal marijuana in treating PTSD. Various combinations of the following search terms were used: marijuana, medicinal marijuana, cannabis, cannabinoid, PTSD, efficacy, trial, and neurobiology. Study Selection: Full text of each article was reviewed, and those directly addressing the question of efficacy of medicinal marijuana on PTSD symptomatology were included. Data were extracted from a total of 46 articles. Results: Analysis revealed that most reports are correlational and observational in basis with a notable lack of randomized, controlled studies. Many of the published studies suggest a decrease in PTSD symptoms with marijuana use. Though the directionality of cannabis use and PTSD could not be fully differentiated at this time, there appears to also be a correlation between PTSD and problematic cannabis use. Despite this finding, there is a growing amount of neurobiological evidence and animal studies suggesting potential neurologically based reasons for the reported efficacy. Conclusions: Posttraumatic stress disorder is 1 of the approved conditions for medicinal marijuana in some states. While the literature to date is suggestive of a potential decrease in PTSD symptomatology with the use of medicinal marijuana, there is a notable lack of large-scale trials, making any final conclusions difficult

    Tic disorders impact quality of life, but when they are co-occurring with attention-deficit/hyperactivity disorder, the combined impact takes a toll on psychosocial functioning and adds another layer of complexity to treatment approaches. A review of the current literature supports evidence of a unique relationship between comorbid attention-deficit/hyperactivity disorder and tic disorders, emphasizing the intricate phenotype and impairment associated with these co-occurring conditions. The complexity of these symptoms requires careful diagnosis and appropriate treatment as determined by the level of impairment and can include pharmacotherapy, behavioral interventions, or a combination of therapies. To achieve the greatest benefits in improving quality of life and eliminating further comorbidity, an ideal treatment plan would include a comprehensive evaluation as well as a hierarchical treatment approach involving education of the child, family, and teachers; careful medication management; and cognitive and behavioral training.

    Case report. To describe a rare case of cervical spondylolysis with an adjacent secondary dysplastic change, and to review the current literature regarding cervical spondylolysis. Three patients presented with minor trauma history and radiographical C6 level spondylolysis. Cervical spines were analyzed with plain radiography, multidetector computerized tomography, and magnetic resonance imaging. In all 3 patients, plain radiographs revealed a bilateral cleft of the C6 articular mass. The patients presented with long-term minimal discomfort of the posterior neck. In 2 patients, a trauma event increased the pain and produced neurologic deficits. In addition, an adjacent dysplastic change was present on imaging studying in 2 of the patients, 1 of whom also presented with a cord signal change above the spondylolytic level. Early diagnosis and appropriate management of cases of spondylolysis are important. In addition, surgical plans for cervical spondylolysis should be considered if the adjacent levels are unstable or fragile.

    Full Text Available Periodic Fever, Aphthous Stomatitis, Pharyngitis and Cervical Adenitis syndrome (PFAPA is a frequently seen, important medical condition, which must be kept in mind in periodic fever etiology. Although its etiology is not clearly understood, autoimmune etiology is suspected due to response to steroids. There is no specific test for the diagnosis of disease. Diagnosis is based on symptoms and physical examination. Although medical treatment is the first choice for the management of the disease, tonsillectomy take over in treatment options for termination of attacks and permanent results. We have presented a patient that was performed tonsillectomy in our clinic for frequent attacks despite recurrent medical therapy with diagnosis of PFAPA with review of current literature.

    2015-01-01

    Full Text Available The paper describes a 44-year-old male patient with an about 6-year history of hypertrophic pachymeningitis. The major clinical symptoms were characterized by headache, exophthalmos, and blindness in one eye. The data for differential diagnosis of the disease are given. The current literature on the clinical manifestations of hypertrophic pachymeningitis, its differential diagnosis, and the results of magnetic resonance imaging (MRI is reviewed. Diagnostic difficulties at the stage of a clinical observation are due to the nonspecificity of neurological manifestations and the need for a comprehensive examination to detect a somatic disease. MRI can diagnose the disease-specific phenomenon of damage to the meninges, which calls for further careful differentiation. Clinicians must be familiar with alternative differential diagnosis, as a rapid specific therapeutic approach will help avoid long-term or irreversible neurological complications.

    New treatment options such as noninvasive brain stimulation have been recently explored in the field of substance use disorders (SUDs), including transcranial direct current stimulation (tDCS). In light of this, we have performed a review of the scientific literature to assess efficacy and technical and methodological issues resulting from applying tDCS to the field of SUDs. Our analysis highlighted the following selection criteria: clinical studies on tDCS and SUDs (alcohol, caffeine, cannabis, cocaine, heroin, methamphetamine, and nicotine). Study selection, data analysis, and reporting were conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Exclusion criteria were as follows: clinical studies about tDCS among behavioral addiction; review and didactic articles; physiopathological studies; and case reports. Eighteen scientific papers were selected out of 48 articles. Among these, 16 studied the efficacy of tDCS applied to the dorsolateral prefrontal cortex, and 8 suggested the efficacy of tDCS in reducing substance craving. In light of these data, it is premature to conclude that tDCS over the dorsolateral prefrontal cortex is a very efficient technique in reducing craving. Small sample size, different stimulation protocols, and study duration were the main limitations. However, the efficacy of tDCS in treating SUDs requires further investigation.

    Despite the increasing number of medications recently approved to treat obesity among adults, few agents have been formally evaluated in children or adolescents for this indication. Moreover, there is a paucity of guidance in the literature addressing best practices with regard to pediatric obesity pharmacotherapy clinical trial design, and only general recommendations have been offered by regulatory agencies on this topic. The purposes of this article are to (1) offer a background of the current state of the field of pediatric obesity medicine, (2) provide a brief review of the literature summarizing pediatric obesity pharmacotherapy clinical trials, and (3) highlight and discuss some of the unique aspects that should be considered when designing and conducting high-quality clinical trials evaluating the safety and efficacy of obesity medications in children and adolescents. Suggestions are offered in the areas of target population and eligibility criteria, clinical trial end-point selection, trial duration, implementation of lifestyle modification therapy and recruitment and retention of participants. Efforts should be made to design and conduct trials appropriately to ensure that high-quality evidence is generated on the safety and efficacy of various medications used to treat pediatric obesity.

    Antiarrhythmic drugs are commonly prescribed cardiac drugs. Due to their receptor mimicry with several of the gastrointestinal tract receptors, they can frequently lead to gastrointestinal side effects. These side effects are the most common reasons for discontinuation of these drugs by the patients. Knowledge of these side effects is important for clinicians that manage antiarrhythmic drugs. This review focuses on the gastrointestinal side effects of these drugs and provides a detailed up-to-date literature review of the side effects of these drugs. The review provides case reports reported in the literature as well as possible mechanisms that lead to gastrointestinal side effects.

    Full Text Available The present study aims to review current thinking and understanding of the issue of Intercultural Communicative Competence (ICC especially in foreign language education contexts. There are serious stances on the part of scholars in foreign language contexts, which must be given some serious thinking and consideration in order to uncover the hidden agendas regarding ICC. After all, it seems still unclear in English as a Foreign Language (EFL contexts whether to try to improve the way of thinking regarding the perspective of current intercultural communicative competence, whether there should be a separation of the cultural values from the target language and only integrate language learners’ native culture with the target language. Given the development of technology and globalization, what is the right thing to do? This is a serious issue which needs much attention and contemplation by the interested scholars. By presenting the existing gaps in the literature, the paper maneuvers on the challenging notes on benefiting from culture in English Language Teaching (ELT and, on the other hand, dividing language and culture by merely elaborating on the communicative aspect of language learning and teaching. The study puts the audience into question that although recent views are focusing on taking English as an international means of communication, there exist serious beliefs regarding the separation of language and culture, which demands more thinking and probably serious revisions.

Generic medicines provide the same therapeutic outcomes but at a much cheaper cost, so are promoted in many countries to contain pharmaceutical expenditure and sustain the health care system. Thus, the perspective of patients and medicine consumers as end users of these medicines is an important factor to enhance the use and utilization of generic medicines. The objective of this paper is to review patients’ and consumers’ knowledge, perceptions, acceptance, and views of generic medicines in the current literature. Methods: An extensive literature search was performed in several databases, namely Scopus, PubMed, ISI Web of Knowledge, Proquest, and the Wiley online library, to identify relevant studies published in the English literature for the period 1990–2013. Results: A total of 53 studies were included in the review, comprising 24 studies from Europe, ten from North America, six from Asia, five from Australia and New Zealand, five from the Middle East, one from Africa, one from Latin America, and one from the Caribbean region. A large body of literature has reported misconceptions and negative perceptions about generic medicines on the part of patients and medicine consumers. Moreover, although it is reported in almost all countries, the percentage of consumers who had

    To systematically identify and analyse all published literature relating to the provision of undergraduate education for preparedness in ear, nose and throat (ENT) surgery, as perceived by medical students and clinicians in the UK. Systematic literature review. 5 major databases were searched: MEDLINE, EMBASE, ERIC, Cochrane and Web of Science. The literature search was conducted from February to April 2015. Primary research or studies that report on the provision of undergraduate education for preparedness in ENT, from the perspective of medical students and clinicians in the UK. The timescale of searches was limited from 1999 onwards (ie, the past 15 years). The literature search was conducted by 2 independent reviewers. Search terms used involved the combination and variation of 5 key concepts, namely: medical student, clinician, ENT, undergraduate medical education and UK. A data extraction form was designed for and used in this study, based on guidelines provided by the UK National Health Service (NHS) Centre for Reviews and Dissemination. Textual narrative synthesis was used for data analysis. A total of 7 studies were included in the final review. 4 main themes were identified: confidence in managing patients, teaching delivery, student assessment and duration of rotations. A consistent finding in this review was that the majority of final year medical students and junior doctors did not feel adequately prepared to practise ENT. Important factors influencing preparedness in ENT included the duration of clinical rotations, the opportunity for hands-on learning and formal assessment. The findings of this review suggest the need for further development of the ENT undergraduate curricula across the UK. However, there is insufficient evidence from which to draw strong conclusions; this in itself is beneficial as it highlights a gap in the existing literature and supports the need for primary research.

    This paper reviews three recent reports of national gender trends in dental practice patterns. Although the three independent cross-sectional studies were conducted at different points in time, used different sampling strategies, and used similar but independent survey instruments, findings were consistent across studies. In summary: Women dentists are less likely to be married and have fewer children. Women are more likely to assume child rearing and household responsibilities. Women are less likely to be practice owners. Women worked slightly fewer hours per week and weeks per year, and were more likely to take a leave of absence for illness or child rearing. However, women dentists demonstrate a far greater professional work commitment than was previously reported in the literature. Women earn significantly less income from the practice of dentistry, even after controlling for age, practice ownership, hours worked per week, and other personal characteristics. The most current "Gender Wage Gap" estimates range from 57.7% for specialists to 75.4% for general practitioners (8). delta.

    Full Text Available Medication error (ME is the most common single preventable cause of adverse drug events which negatively affects patient safety. ME prevalence is a valuable safety indicator in healthcare system. Inadequate studies on ME, shortage of high-quality studies and wide variations in estimations from developing countries including Iran, decreases the reliability of ME evaluations. In order to clarify the status of MEs, we aimed to review current available literature on this subject from Iran. We searched Scopus, Web of Science, PubMed, CINAHL, EBSCOHOST and also Persian databases (IranMedex, and SID up to October 2012 to find studies on adults and children about prescription, transcription, dispensing, and administration errors. Two authors independently selected and one of them reviewed and extracted data for types, definitions and severity of MEs. The results were classified based on different stages of drug delivery process. Eighteen articles (11 Persian and 7 English were included in our review. All study designs were cross-sectional and conducted in hospital settings. Nursing staff and students were the most frequent populations under observation (12 studies; 66.7%. Most of studies did not report the overall frequency of MEs aside from ME types. Most of studies (15; 83.3% reported prevalence of administration errors between 14.3%-70.0%. Prescribing error prevalence ranged from 29.8%-47.8%. The prevalence of dispensing and transcribing errors were from 11.3%-33.6% and 10.0%-51.8% respectively. We did not find any follow up or repeated studies. Only three studies reported findings on severity of MEs. The most reported types of and the highest percentages for any type of ME in Iran were administration errors. Studying ME in Iran is a new area considering the duration and number of publications. Wide ranges of estimations for MEs in different stages may be because of the poor quality of studies with diversity in definitions, methods, and populations

    Persistent vomiting is mentioned as a symptom of a large variety of systemic disorders. It is commonly used interchangeably with chronic, recurrent, or intractable vomiting and widely used as a warning sign of severe illness in dengue infection. However, it has been poorly defined in the medical literature. Therefore, we aimed to systematically review a definition of persistent vomiting in the medical literature. A systematic search was done through; PubMed, Google Scholar, Web of Science, Scopus, VHL, WHO-GHL, Grey Literature Report, POPLINE, and SIGLE for the last 10 years. Consensus on the definition was considered to be reached if at least 50% of studies described the same definition using the Delphi consensus technique. Of 2362 abstracts reviewed, 15 studies were selected based on the inclusion criteria. Three studies used the same definition. Another 2 studies defined it as vomiting of all foods and fluid in 24 hours. Three studies defined persistent vomiting in the units of days or weeks. Four studies used the number of episodes: ≥2 episodes 15 minutes apart, >3 episodes in 12 hours, and >3 episodes within 24 hours. No consensus for the definition was found among authors. This is a point of concern that needs to be addressed by further studies.

    2015-01-01

    The purpose of the literature review was to assess the origins of radiology physician extenders and examine the current roles found in the literature of advanced practice physician extenders within medical imaging. Twenty-six articles relating to physician assistants (PAs), nurse practitioners (NPs), radiologist assistants (RAs), and nuclear medicine advanced associates (NMAAs) were reviewed to discern similarities and differences in history, scope of practice, and roles in the medical imaging field. The literature showed PAs and NPs are working mostly in interventional radiology. PAs, NPs, and RAs perform similar tasks in radiology, including history and physicals, evaluation and management, preprocedure work-up, obtaining informed consent, initial observations/reports, and post-procedure follow-up. NPs and PAs perform a variety of procedures but most commonly vascular access, paracentesis, and thoracentesis. RAs perform gastrointestinal, genitourinary, nonvascular invasive fluoroscopy procedures, and vascular access procedures. The review revealed NMAAs are working in an advanced role, but no specific performances of procedures was found in the literature, only suggested tasks and clinical competencies. PAs, NPs, and RAs are currently the three main midlevel providers used in medical imaging. These midlevel providers are being used in a variety of ways to increase the efficiency of the radiologist and provide diagnostic and therapeutic radiologic procedures to patients. NMAAs are being used in medical imaging but little literature is available on current roles in clinical practice. More research is needed to assess the exact procedures and duties being performed by these medical imaging physician extenders.

  9. Taxonomic Review of Classical and Current Literature on the Perennial American Family Forest Problem

    Directory of Open Access Journals (Sweden)

    Thomas J. Straka

    2011-08-01

    Full Text Available One of the fundamental issues in American forest policy has been the small forest ownership problem. Early in the twentieth century, it was called the farm forestry problem, later, the nonindustrial private forest problem, and today, the family forest problem. Family forest owners are thought to manage their lands in a suboptimal manner resulting in low forest productivity relative to other ownership groups. This can lead to future timber supply problems. The exact nature of the problem, especially its social and economic basis, was a common subject of early forestry research studies. This article includes many of the major nonindustrial private forest or family forest studies, from early to current, and classifies them both by themes used by other authors and categories that relate to major research areas in the current literature. A major focus of this literature deals with promoting management on family forest holdings and possible land management incentives and disincentives. Natural trends in family forest ownership, like parcelization, also impact upon forest management opportunities. By developing a taxonomy that classifies these studies by research objective, methodology, owner motivation, and problem definition, this article serves to organize the family forest literature in a manner that provides a temporal framework for better understanding the historical motivation for and development of family forest research in the United States.

    Interprofessional education (IPE) is becoming essential for students and healthcare professionals. An evolving approach to implement it is via distance education. Distance education can provide a viable solution to deliver IPE in a variety of settings. A literature search on PubMed and Academic Search Complete databases was conducted, revealing 478 articles ranging from the years of 1971-2015. The articles were screened for relevance using the following inclusion criteria: 1) Is this study implementing IPE? 2) Is this study utilizing the instructional delivery method of distance education? 3) Does this study contain students from two or more healthcare professions? Fifteen studies met the inclusion criteria and were systematically analyzed to identify data relevant for this review. Findings from this review provide a description of the teaching methods involved in distance education in promoting IPE and an assessment of the continuing use of distance education to foster IPE. Success varied depending upon on the distance-based instructional model utilized to facilitate IPE. Incorporating distance education to implement IPE can be an opportunity to develop team collaboration and communication skills among students. Teaching models presented in this review have the potential to be adapted to methods that leverage the power of evolving technology. Further research is needed to understand which distance education instructional delivery models best maximize the IPE experience. Copyright © 2017 Elsevier Inc. All rights reserved.

    2010-01-01

    The purpose of this article is to discuss the current state of implementation of Lean production in health care. The study focuses on the definition of Lean in health care and implementation process, barriers, challenges, enablers, and outcomes of implementing Lean production methods in health care. A comprehensive search of the literature concerning the implementation of Lean production in health care was used to generate a synthesis of the literature around the chosen research questions. Lean production in health care is mostly used as a process improvement approach and focuses on 3 main areas: (1) defining value from the patient point of view, (2) mapping value streams, and (3) eliminating waste in an attempt to create continuous flow. Value stream mapping is the most frequently applied Lean tool in health care. The usual implementation steps include conducting Lean training, initiating pilot projects, and implementing improvements using interdisciplinary teams. One of the barriers is lack of educators and consultants who have their roots in the health care sector and can provide support by sharing experience and giving examples from real-life applications of Lean in health care. The enablers of Lean in health care seem not to be different from the enablers of any other change initiative. The outcomes can be divided into 2 broad areas: the performance of the health care system and the development of employees and work environment.

    2014-11-01

    Full Text Available This article considers selected drivers of decision variability in child welfare decision-making and explores current debates in relation to these drivers. Covering the related influences of national orientation, risk and responsibility, inequality and poverty, evidence-based practice, constructions of abuse and its causes, domestic violence and cognitive processes, it discusses the literature in regards to how each of these influences decision variability. It situates these debates in relation to the ethical issue of variability and the equity issues that variability raises. I propose that despite the ecological complexity that drives decision variability, that improving internal (within-country decision consistency is still a valid goal. It may be that the use of annotated case examples, kind learning systems, and continued commitments to the social justice issues of inequality and individualisation can contribute to this goal.

    2016-06-01

    Childhood obesity is a significant problem in the United States, but current childhood obesity prevention approaches have limited efficacy. Self-regulation processes organize behavior to achieve a goal and may shape health behaviors and health outcomes. Obesity prevention approaches that focus on the cognitive and behavioral mechanisms that underlie self-regulation early in life may therefore lead to better outcomes. This article reviews the development of executive functioning (EF), identifies influences on EF development, discusses aspects of EF relating to increased risk for childhood obesity, and considers how EF-weight associations may change across development. Implications for intervention are discussed. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Business incubators (BIs are a significant tool in promoting the development of entrepreneurial firms, technology-based growth firms and economic growth in South Africa. The study reviewed the current literature on business incubation in South Africa. BIs in South Africa emerged as a popular strategy in the 1990s and most of the current literature was established in the same period. However, the current literature is still limited. The aim of this paper is to provide an overview of existing knowledge on the role and effectiveness of business incubation in supporting the development of new small startup businesses. The quantitative and qualitative literature published by the academic and practitioner communities is reviewed. The searches indicated that incubation has encouraged many studies in South Africa. The studies can be categorised under the following themes: the role and contribution of incubators, success factors for business incubation, obstacles, and the relationship between incubators and entrepreneurship. The areas for further research are suggested. Two major areas that new research can explore focus on the creation of the model and selfsustainability of BIs.

    Background Interest in mindfulness has increased exponentially, particularly in the fields of psychology and medicine. The trait or state of mindfulness is significantly related to several indicators of psychological health, and mindfulness-based therapies are effective at preventing and treating many chronic diseases. Interest in mobile applications for health promotion and disease self-management is also growing. Despite the explosion of interest, research on both the design and potential uses of mindfulness-based mobile applications (MBMAs) is scarce. Objective Our main objective was to study the features and functionalities of current MBMAs and compare them to current evidence-based literature in the health and clinical setting. Methods We searched online vendor markets, scientific journal databases, and grey literature related to MBMAs. We included mobile applications that featured a mindfulness-based component related to training or daily practice of mindfulness techniques. We excluded opinion-based articles from the literature. Results The literature search resulted in 11 eligible matches, two of which completely met our selection criteria–a pilot study designed to evaluate the feasibility of a MBMA to train the practice of “walking meditation,” and an exploratory study of an application consisting of mood reporting scales and mindfulness-based mobile therapies. The online market search eventually analyzed 50 available MBMAs. Of these, 8% (4/50) did not work, thus we only gathered information about language, downloads, or prices. The most common operating system was Android. Of the analyzed apps, 30% (15/50) have both a free and paid version. MBMAs were devoted to daily meditation practice (27/46, 59%), mindfulness training (6/46, 13%), assessments or tests (5/46, 11%), attention focus (4/46, 9%), and mixed objectives (4/46, 9%).

    Interest in mindfulness has increased exponentially, particularly in the fields of psychology and medicine. The trait or state of mindfulness is significantly related to several indicators of psychological health, and mindfulness-based therapies are effective at preventing and treating many chronic diseases. Interest in mobile applications for health promotion and disease self-management is also growing. Despite the explosion of interest, research on both the design and potential uses of mindfulness-based mobile applications (MBMAs) is scarce. Our main objective was to study the features and functionalities of current MBMAs and compare them to current evidence-based literature in the health and clinical setting.

    Disorders of orgasm in women, defined as the persistent or recurrent delay in or absence of orgasm, affect up to a quarter of the female population. To review existing research findings on the etiology and treatments of disorders of orgasm in women to provide a useful reference tool for clinicians who evaluate and treat patients with these conditions. PubMed and PsycINFO search for articles published between 1980 and 2009 using the keywords "orgasm*,"anorgasmia," and "female*,"woman," or "women," in addition to "female orgasmic disorder" and "disorders of orgasm in women." Findings on the etiological factors and effects of a variety of treatment interventions on improving disorders of orgasm in women. Results.  Literature on prevalence and causes of disorders of orgasm in women is abundant, yet more reports of successful treatments are needed. Nevertheless, many promising approaches have been suggested, and data support several potential treatments such as bupropion, sildenafil, estrogen, and testosterone among others. Although more research is needed to better understand and manage disorders of orgasm in women, significant progress is being made. © 2010 International Society for Sexual Medicine.

  18. Current State of Development of Electricity-Generating Technologies: A Literature Review

    Full Text Available Electricity is perhaps the most versatile energy carrier in modern economies, and it is therefore fundamentally linked to human and economic development. Electricity growth has outpaced that of any other fuel, leading to ever-increasing shares in the overall mix. This trend is expected to continue throughout the following decades, as large—especially rural—segments of the world population in developing countries start to climb the “energy ladder” and become connected to power grids. Electricity therefore deserves particular attention with regard to its contribution to global greenhouse gas emissions, which is reflected in the ongoing development of low-carbon technologies for power generation. The focus of this updated review of electricity-generating technologies is twofold: (a to provide more technical information than is usually found in global assessments on critical technical aspects, such as variability of wind power, and (b to capture the most recent findings from the international literature. This report covers eight technologies. Seven of these are generating technologies: hydro-, nuclear, wind, photovoltaic, concentrating solar, geothermal and biomass power. The remaining technology is carbon capture and storage. This selection is fairly representative for technologies that are important in terms of their potential capacity to contribute to a low-carbon world economy.

    Balancing selection has been widely assumed to be an important evolutionary force, yet even today little is known about its abundance and its impact on the patterns of genetic diversity. Several studies have shown examples of balancing selection in humans, plants or parasites, and many genes under balancing selection are involved in immunity. It has been proposed that host-parasite coevolution is one of the main forces driving immune genes to evolve under balancing selection. In this paper, we review the literature on balancing selection on immunity genes in several organisms, including Drosophila. Furthermore, we performed a genome scan for balancing selection in an African population of Drosophila melanogaster using coalescent simulations of a demographic model with and without selection. We find very few genes under balancing selection and only one novel candidate gene related to immunity. Finally, we discuss the possible causes of the low number of genes under balancing selection.

    Diabetic foot ulcers (DFUs) are a very common cause of mortality and morbidity. The distinction between infected and non-infected DFU remains a very challenging task for clinicians in everyday practice. Even when infection is documented, the spectrum of diabetic foot infection is wide, ranging from cellulitis and soft tissue infection to osteomyelitis. Procalcitonin (PCT), a well-established sepsis biomarker, has been used in the diagnosis of several infections including osteomyelitis in patients with diabetes mellitus. This review gathers and presents all the relevant data, up until now, regarding the use of PCT as an assessment tool in diabetic patients with foot infection. Current evidence suggests that PCT levels could aid clinicians in distinguishing infected from non-infected DFUs as well as in the distinction between soft tissue infection and bone involvement, but further and larger studies are warranted to confirm these findings.

    2016-01-01

    The management of pancreaticobiliary disease in patients with surgically altered anatomy is a growing problem for gastroenterologists today. Over the years, endoscopic ultrasound (EUS) has emerged as an important diagnostic and therapeutic modality in the treatment of pancreaticobiliary disease. Patient anatomy has become increasingly complex due to advances in surgical resection of pancreaticobiliary disease and EUS has emerged as the therapy of choice when endoscopic retrograde cholangiopancreatography failed cannulation or when the papilla is inaccessible such as in gastric obstruction or duodenal obstruction. The current article gives a comprehensive review of the current literature for EUS-guided intervention of the pancreaticobiliary tract in patients with altered surgical anatomy. PMID:27386471

    2016-09-01

    Patients with pectus excavatum (PE) often describe improvements in exercise stamina following corrective surgery. Studies have investigated the surgical effect on physiological parameters; still, no consensus has yet been reached. Therefore, the aim of this literature review was to describe the cardiac outcome after surgical correction, both at rest and during exercise. In February 2016, a detailed search of the databases PubMed, Medline, and EMBASE was performed. We assessed clinical studies that described cardiac outcomes both before and after surgical correction of PE. We only included studies reporting either pre-defined echocardiographic or exercise test parameters. No exclusion criteria or statistical analyses were applied. Twenty-one full-text articles, published between 1972 and 2016, were selected, with cohort-ranges of 3-168 patients, mean age-ranges of 5-33 years, and mean follow-up-ranges from immediately to 4 years after surgery. Twelve studies described resting cardiac parameters. Four studies measured cardiac output, where one described 36% immediate increase after surgery, one reported 15% increase after Nuss-bar removal and two found no difference. Three studies demonstrated improvement in mean stroke volume ranges of 22-34% and two studies found no difference. Fifteen studies investigated exercise capacity, with 11 considering peak O 2 pr. kg, where five studies demonstrated improvements with the mean ranging from 8% to 15% after surgery, five studies demonstrated no difference, and one saw a decrease of 19% 3 months after Nuss-bar implantation. A measurable increase in exercise capacity exists following surgery, which may be caused by multiple factors. This may be owed to the relief of compressed cardiac chambers with the increased anterior-posterior thoracic dimensions, which could facilitate an improved filling of the heart. With these results, the positive physiological impact of the surgery is emphasized and the potential gain in cardiac

    In facial plastic surgery, the potential for direct delivery of growth factors from platelet preparations has been of particular interest for use in facial rejuvenation, recovery after facial surgery, and wound healing. A literature search was conducted through PubMed for the terms PRP, PRFM, platelet-rich plasma, platelet-rich fibrin matrix, platelet preparations, platelet therapy, growth factors, platelet facial, platelet facial rejuvenation, platelet wound healing, platelet plastic surgery. Articles pertaining to the use of platelet preparations in facial surgery and wound healing in plastic surgery after 2001 were included. Thirteen in vitro studies showed use of platelet-rich plasma (PRP) and platelet-rich fibrin matrix (PRFM) had a significant effect on cellular activity. Twenty-four out of 28 animal studies exhibited favorable results with use of a platelet preparation, including five of six studies that showed enhanced fat graft survival with addition of a platelet preparation. Twenty-three case series and clinical trials were identified, only two of which showed no differences. Twenty-one reported favorable results with use of various platelet preparations. A total of 47 studies used PRP, four studies evaluated Leukocyte-rich PRP, and fourteen studies used PRFM. The vast majority of studies examined show a significant and measurable effect on cellular changes, wound healing, and facial esthetic outcomes with use of platelet preparations, both topical and injectable. One must also consider possible publication bias against null results that may have had an influence on the data that were available for review. However, the preponderance of studies suggests that platelet preparations might represent an as-of-yet untapped adjunct in facial plastic surgery.

  4. Unilateral hearing loss in children: a retrospective study and a review of the current literature.

    Despite the introduction of universal newborn hearing screening (UNHS), unilateral hearing loss (UHL) is sometimes recognized late. This diagnostic delay has adverse repercussions, given the importance of binaural hearing for the development of normal auditory processing. It is incorrect to maintain that unilateral hearing is the minimum requirement for adequate speech development and that hearing aid provision is consequently unnecessary. In our retrospective study, hearing aid provision resulted in improved directional and selective hearing (quiet and noisy environments) and, compared with their chronically ill counterparts, the children in our study displayed superior health-related quality of life (HRQoL) scores in all areas. On the basis of the results, the authors conclude that even mild hearing losses (from an auditory threshold of 30 to 40 dB) should have the opportunity for hearing aid provision. A selective literature review was conducted in PubMed and textbooks and with reference to national and international guidelines. Early diagnosis and treatment of UHL have a positive effect on verbal-cognitive, linguistic, communicative, and socio-emotional development, as demonstrated by neurophysiological studies. Among the treatment modalities with differing effects on the quality of binaural hearing, cochlear implants are now used increasingly in children with hearing loss bordering on deafness. Published evidence and clinical experience support early diagnosis and treatment. Wherever feasible, hearing aid provision before or at the end of the first year of life is recommended for children with UHL. What is Known: • Almost 30 years ago, poor academic performance was reported in children with unilateral hearing loss (UHL). • Despite improvements in treatment options, it is traditionally held that unilateral hearing is the minimum requirement for adequate speech development and hearing aid provision is unnecessary. What is New: • Academic and behavioral

    Over the last few years, many studies have focused on embryo selection methods, whereas little attention has been given to the standardization of the procedure of embryo transfer. In this review, several parameters of the embryo transfer procedure are examined, such as the: (i) culture medium volume and loading technique; (ii) syringe and catheters used for embryo transfer; (iii) viscosity and composition of the embryo transfer medium; (iv) environment of embryo culture; (v) timing of embryo transfer; (vi) and standardization of the embryo transfer techniques. The aim of this manuscript is to review these factors and compare the existing embryo transfer techniques and highlight the need for better embryo transfer standardization.

    2017-05-01

    OBJECTIVE Surgical robotics has demonstrated utility across the spectrum of surgery. Robotics in spine surgery, however, remains in its infancy. Here, the authors systematically review the evidence behind robotic applications in spinal instrumentation. METHODS This systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Relevant studies (through October 2016) that reported the use of robotics in spinal instrumentation were identified from a search of the PubMed database. Data regarding the accuracy of screw placement, surgeon learning curve, radiation exposure, and reasons for robotic failure were extracted. RESULTS Twenty-five studies describing 2 unique robots met inclusion criteria. Of these, 22 studies evaluated accuracy of spinal instrumentation. Although grading of pedicle screw accuracy was variable, the most commonly used method was the Gertzbein and Robbins system of classification. In the studies using the Gertzbein and Robbins system, accuracy (Grades A and B) ranged from 85% to 100%. Ten studies evaluated radiation exposure during the procedure. In studies that detailed fluoroscopy usage, overall fluoroscopy times ranged from 1.3 to 34 seconds per screw. Nine studies examined the learning curve for the surgeon, and 12 studies described causes of robotic failure, which included registration failure, soft-tissue hindrance, and lateral skiving of the drill guide. CONCLUSIONS Robotics in spine surgery is an emerging technology that holds promise for future applications. Surgical accuracy in instrumentation implanted using robotics appears to be high. However, the impact of robotics on radiation exposure is not clear and seems to be dependent on technique and robot type.

    2014-01-01

    Statement of Problem. Direct metal laser sintering (DMLS) is a technology that allows fabrication of complex-shaped objects from powder-based materials, according to a three-dimensional (3D) computer model. With DMLS, it is possible to fabricate titanium dental implants with an inherently porous surface, a key property required of implantation devices. Objective. The aim of this review was to evaluate the evidence for the reliability of DMLS titanium dental implants and their clinical and histologic/histomorphometric outcomes, as well as their mechanical properties. Materials and Methods. Electronic database searches were performed. Inclusion criteria were clinical and radiographic studies, histologic/histomorphometric studies in humans and animals, mechanical evaluations, and in vitro cell culture studies on DMLS titanium implants. Meta-analysis could be performed only for randomized controlled trials (RCTs); to evaluate the methodological quality of observational human studies, the Newcastle-Ottawa scale (NOS) was used. Results. Twenty-seven studies were included in this review. No RCTs were found, and meta-analysis could not be performed. The outcomes of observational human studies were assessed using the NOS: these studies showed medium methodological quality. Conclusions. Several studies have demonstrated the potential for the use of DMLS titanium implants. However, further studies that demonstrate the benefits of DMLS implants over conventional implants are needed.

  19. Effects of colchicine on pericardial diseases: a review of the literature and current evidence

    Directory of Open Access Journals (Sweden)

    Syed Raza Shah

    2016-07-01

    Full Text Available Colchicine, extracted from the colchicum autumnale plant, used by the ancient Greeks more than 20 centuries ago, is one of the most ancient drugs still prescribed even today. The major mechanism of action is binding to microtubules thereby interfering with mitosis and subsequent modulation of polymorphonuclear leukocyte function. Colchicine has long been of interest in the treatment of cardiovascular disease; however, its efficacy and safety profile for specific conditions have been variably established in the literature. In the subset of pericardial diseases, colchicine has been shown to be effective in recurrent pericarditis and post-pericardiotomy syndrome (PPS. The future course of treatment and management will therefore highly depend on the results of the ongoing large randomized placebo-controlled clinical trial to evaluate the efficacy and safety of colchicine for the primary prevention of several postoperative complications and in the perioperative period. Also, given the positive preliminary outcomes of colchicine usage in pericardial effusions, the future therapeutical use of colchicine looks promising. Further study is needed to clarify its role in these disease states, as well as explore other its role in other cardiovascular conditions.

    One important modality of breast cancer therapy is surgical treatment, which has become increasingly less mutilating over the last century. Breast reconstruction has become an integrated part of breast cancer treatment due to long-term psychosexual health factors and its importance for breast cancer survivors. Both autogenous tissue-based and implant-based reconstruction provides satisfactory reconstructive options due to better surgeon awareness of "the ideal breast size", although each has its own advantages and disadvantages. An overview of the current options in breast reconstruction is presented in this article.

    2017-07-01

    Social media, including blogs, Twitter, wikis, Facebook, YouTube, and Ning, provides an opportunity for nurse educators to engage undergraduate nursing students who are members of the millennial generation in active learning while enhancing knowledge and fostering communication. Despite the rise of social media usage in undergraduate nursing education, there is a significant deficiency of empirical evidence supporting the efficacy and outcomes of these teaching strategies. This article provides an overview of social media use in undergraduate nursing education and a review of the existing research related to social media use in prelicensure nursing education. Overall, undergraduate nursing students respond positively to social media use in nursing education; however, no outcome measures are available to determine the effect of these teaching strategies on student learning.

    2008-01-01

    Primary liver cancer remains one of the most lethal malignancies worldwide. Due to differences in prevalence of etiological factors the incidence of primary liver cancer varies among the world, with a peak in East-Asia. As this disease is still lethal in most of the cases, research has to be done to improve our understanding of the disease, offering insights for possible treatment options. For this purpose, animal models are widely used, especially mouse models. In this review, we describe the different types of mouse models used in liver cancer research, with emphasis on genetically engineered mice used in this field. We focus on hepatocellular carcinoma (HCC), as this is by far the most common type of primary liver cancer, accounting for 70%-85% of cases. PMID:19058325

    We report a case of a 51 years old female with a 25 pack year smoking history who underwent bilateral mastectomy and immediate tissue expander reconstruction for newly diagnosed right breast cancer. The patient reported herself as a non-smoker despite significant e-cigarette use, with resulting significant mastectomy skin flap necrosis and breast reconstruction failure. Little is known about the physiologic effect of e-cigarettes on wound healing and tissue perfusion. To this end, we provide an updated review of the impact of e-cigarettes on surgical outcomes. PubMed, Ovid MEDLINE, and PRS GO were searched for the terms "e-cigarette", "electronic cigarette", "e-cig", "electronic nicotine delivery system", "vaping", "surgery", "surgical", "peri-operative", "operate", "operative", and "wound healing". Abstract review of all articles was performed. 123 articles returned that contained both variants of e-cigarettes and surgery as keywords. Of those, manual assessment returned three articles which were found to be relevant to e-cigarette use in the surgical patient. No articles were found that compared perioperative complications in e-cigarette versus traditional cigarette users in humans. In conclusion, our case report depicts the potential dangers associated with e-cigarette use in the surgical patient. There is a public misconception that e-cigarettes are healthier than traditional cigarettes and as such their use may go unreported by patients. Early evidence suggests e-cigarettes may induce some of the same physiologic changes as traditional cigarettes, and may have a significant deleterious effect on wound healing.

    2012-01-01

    Enterobius vermicularis or "pinworm" infection of the liver is an extremely rare condition with only five cases previously reported in literature. It is characterized by the presence of granulomas in the liver with a necrotic core, containing adult helminthes or their ova. Because of the relatively mild symptomatology associated with this disease, prior to the arrival of modern imaging methods hepatic enterobiasis was an incidental intra-operative finding during abdominal surgery for other conditions. In recent years however, with high-resolution abdominal imaging readily available and the improved safety of hepatic resection, a lower threshold for treating suspicious hepatic nodules aggressively with surgery is being adopted. We present the second case in international literature, where E. vermicularis of the liver was mistaken for malignancy and led to hepatic resection and perform a literature review of the five previously documented cases of hepatic enterobiasis. Our report identifies certain trends in this condition's aetiology and clinical behaviour, but due to its rarity definitive answers cannot yet be established. We do not advocate a change in the current approach of suspicious hepatic nodules, but we do feel that better understanding of the mechanisms involved with hepatic enterobiasis could, in the future, prevent unnecessary surgery.

    2016-05-01

    With the US healthcare system on an unsustainable course, change is inevitable. Changes in the healthcare landscape impacting radiology include changing payment models, rapid adoption of digital technology, changes in radiology resident certifying exams, and the rise of consumerism in health care. Academic Radiology will be part of that change with none of its missions spared. What matters is not that change is coming but how Academic Radiology responds to change. Do we ignore, adapt, adopt others' practices, or lead change? Change management or transformation is a management skill set that can be learned and developed. Transformational leadership is a leadership style defined by the relationships between the leaders and the followers and the results they are able to achieve together to meet organizational goals. In this paper, we provide a review of key change management theories, as well as practical advice for self-reflection and development of leadership behaviors that promote effective change management and organizational transformation, particularly in a complex industry like Academic Radiology.

  17. Role of genetics in the etiopathogenesis of genetic generalized epilepsy: A review of current literature

    2016-01-01

    Full Text Available Until recently, genetic generalized epilepsy (GGE was believed to be of presumed genetic etiology with no identifiable genetic mutation or demonstrable epigenetic abnormality. A wide range of epileptic disorders has clue for an inherited susceptibility. Monogenic disorders associated with epilepsy mental retardation and structural brain lesion typified by heterotopias, tuberous sclerosis, and progressive myoclonus epilepsies account for about 1% of epilepsies. This review focuses on the role of genetic mutations and epigenetic rearrangements in the pathophysiologic mechanism of GGE. To achieve this; PubMed, EMBASE, and Google Scholar were systematically and comprehensively searched using keywords (“epilepsy” “juvenile myoclonic epilepsy (JME,” “typical absences,” “idiopathic generalized epilepsy,” “JME,” “juvenile absence epilepsy,” “childhood absence epilepsy” “generalized tonic-clonic seizure” “GTCS”. Most GGE has evidence of underlying genetic inheritance. Recent animal studies have shown that early detection and treatment of genetic generalized epilepsies can alter the phenotypic presentation in rodents. These findings suggest a critical period in epileptogenesis, during which spike-and-wave seizures can be suppressed, leading to chronic changes in the brain (epileptogenesis and the preceding dysfunctions may, therefore, be targeted using therapeutic approaches that may either delay or inhibit the transition to active epileptic attack. The interplay between genetic mutations and epigenetic rearrangements play important roles in the development of GCE and that this process, especially at crucial developmental periods, is very susceptible to environmental modulations.

  18. Tamsulosin for urolithiasis: a review of the recent literature and current controversies.

    In the United States, urolithiasis affects approximately 1 in 11 people, and there is evidence that the prevalence is increasing. A relatively recent treatment strategy for urolithiasis involves using medical expulsive therapy (MET) to increase the likelihood of spontaneous passage of ureteral stones. The 2 leading drug classes for MET are alpha-1-andrenergic receptor blockers and calcium channel blockers. Tamsulosin, an alpha-1-adrenocepter blocking agent, is thought to induce spontaneous stone passage by relaxing ureteral smooth muscle tone. However, tamsulosin has not been proven effective for increasing ureteral stone passage and is not approved by the Food and Drug Administration for this indication. There is a relative paucity of data on the efficacy of tamsulosin for urolithiasis, and of the published results, there are conflicting conclusions from the data. Because of the acute and often severe nature of symptoms from urolithiasis, emergency medicine physicians are frequently the first to diagnose and treat this condition. This has led to tamsulosin being frequently prescribed from the emergency department (ED) for off-label use without the support of high-quality evidence. If tamsulosin is proven effective, its use in the treatment of urolithiasis could offer several important advantages. The number of procedures, length of hospital stay, and health care costs after the initial ED visit could potentially be reduced. Tamsulosin may also increase patient satisfaction by reducing the invasive treatment and decreasing the time to stone passage. This review focuses on the efficacy of tamsulosin based on stone location, after shock wave lithotripsy, compared with other MET drugs and in the acute setting of the ED.

    2015-01-01

    Full Text Available Stress cardiomyopathy (SCM, also called broken heart syndrome and Takotsubo cardiomyopathy is an increasingly reported syndrome generally characterized by transient systolic dysfunction of the apical and or mid segments of the left ventricle that mimics myocardial infarction, in the absence of obstructive coronary artery disease. Typically patients present within a few hours of exposure to physical or emotional stress. However, the mechanism by which these stressors result in myocardial dysfunction is unclear. Proposed factors include catecholamine excess and coronary vasospasm1. We present the case of a 61-year-old female who experienced acute pulmonary edema secondary to stress cardiomyopathy, on two occasions immediately after undergoing elective direct current cardioversion (DCCV for atrial fibrillation (Afib. After an urgent hospitalization for management of acute left ventricular failure, she made a complete clinical and echocardiographic recovery. The incidence, clinical implications and prognosis of DCCV induced SCM is unknown. Given DCCV for Afib is a common outpatient procedure and DCCV induced SCM can lead to acute clinical deterioration it is important that physicians are vigilant about this newly recognized DCCV complication.

    The application of tracheal cuff pressure monitoring is likely to vary between institutions. The aim of this study was therefore to review current evidence concerning this intervention in the intensive care unit (ICU) and to appraise regional practice by performing a state-wide survey. Publications for review were identified through searches of PubMed, EMBASE and Cochrane (1977 to 2014). All studies in English relevant to critical care and with complete data were included. Survey questions were developed by small-group consensus. Public and private ICUs across Queensland were contacted, with responses obtained from a representative member of the medical or nursing staff. Existing literature suggests significant variability in tracheal cuff pressure monitoring in the ICU, particularly in the applied technique, frequency of assessment and optimal intra-cuff pressures. Twenty-nine respondents completed the survey, representing 80.5% (29/36) of ICUs in Queensland. Twenty-eight out of twenty-nine respondents reported routinely monitoring tracheal cuff function, primarily employing cuff pressure measurement (26/28). Target cuff pressures varied, with 3/26 respondents aiming for 10 to 20 cmH2O, 10/26 for 21 to 25 cmH2O, and 13/26 for 26 to 30 cmH2O. Fifteen out of twenty-nine reported they had no current guideline or protocol for tracheal cuff management and only 16/29 indicated there was a dedicated area in the clinical record for reporting cuff intervention. Our results indicate that many ICUs across Queensland routinely measure tracheal cuff function, with most utilising pressure monitoring devices. Consistent with existing literature, the optimum cuff pressure remains uncertain. Most, however, considered that this should be a routine part of ICU care.

    Recent publications on YouTube have advocated its potential for patient education. However, a reliable description of what could be considered quality information for patient education on YouTube is missing. To identify topics associated with the concept of quality information for patient education on YouTube in the scientific literature. A literature review was performed in MEDLINE, ISI Web of Knowledge, Scopus, and PsychINFO. Abstract selection was first conducted by two independent reviewers; discrepancies were discussed in a second abstract review with two additional independent reviewers. Full text of selected papers were analyzed looking for concepts, definitions, and topics used by its authors that focused on the quality of information on YouTube for patient education. In total, 456 abstracts were extracted and 13 papers meeting eligibility criteria were analyzed. Concepts identified related to quality of information for patient education are categorized as expert-driven, popularity-driven, or heuristic-driven measures. These include (in descending order): (1) quality of content in 10/13 (77%), (2) view count in 9/13 (69%), (3) health professional opinion in 8/13 (62%), (4) adequate length or duration in 6/13 (46%), (5) public ratings in 5/13 (39%), (6) adequate title, tags, and description in 5/13 (39%), (7) good description or a comprehensive narrative in 4/13 (31%), (8) evidence-based practices included in video in 4/13 (31%), (9) suitability as a teaching tool in 4/13 (31%), (10) technical quality in 4/13 (31%), (11) credentials provided in video in 4/13 (31%), (12) enough amount of content to identify its objective in 3/13 (23%), and (13) viewership share in 2/13 (15%). Our review confirms that the current topics linked to quality of information for patient education on YouTube are unclear and not standardized. Although expert-driven, popularity-driven, or heuristic-driven measures are used as proxies to estimate the quality of video information

  4. Current and future prospects for heat recovery from waste in European district heating systems: A literature and data review

    Persson, Urban; Münster, Marie

    2016-01-01

    Municipal solid waste has seen increasing annual volumes for many decades in contemporary Europe and constitutes, if not properly managed, an environmental problem due to local pollution and greenhouse gas emissions. From an energy perspective, waste is also an alternative fuel for power and heat generation; energy recovery from waste represents an effective measure to reduce landfilling and avoid disposal emissions while simultaneously reducing the equivalent demand for primary energy supply. A key factor for obtaining the full synergetic benefits of this energy recovery is the presence of local heat distribution infrastructures, without which no large-scale recovery and utilisation of excess heat is possible. In this paper, which aims to estimate municipal solid waste volumes available for heat recovery in European district heating systems in 2030, a literature and data review is performed to establish and assess current and future EU (European Union) waste generation and management. Main conclusions are that more heat can be recovered from current Waste-to-Energy facilities operating at low average heat recovery efficiencies, that efficient incineration capacity is geographically concentrated, and that waste available for heat recovery in 2030 is equally determined by total generation volumes by this year as by future EU deployment levels of district heating. - Highlights: • European municipal solid waste time series data analysed from 1995 to 2012. • Review of modelling approaches to assess future European waste generation. • Weather corrected district heat data for EU Member States in 1995 and 2012. • Low average heat recovery efficiency in current European waste incineration. • Future heat recovery efficiencies as determinant as future generation volumes.

    To review the current literature on the use of hyperbaric oxygen (HBO₂) therapy in the treatment of osteonecrosis of the femoral head (ONFH). We searched PubMed, Directory of Open Access Journals (DOAJ), EMBASE, Web of Science, Academic Search Complete, CINAHL and MEDLINE through April 2015. We hand-searched relevant textbooks, conference proceedings and the reference lists of review articles and clinical studies Randomized controlled trials (RCT) and observational studies (cohort study, case-control study, case series) that reported the outcome of patients who received HBO₂therapy for ONFH were included. Only English-language articles were included. Study quality was not used as an exclusion criterion. Two authors independently assessed trials for inclusion, extracted data and presented to other authors. Disagreements were resolved by consensus. We identified eight clinical studies; two randomized controlled trials (RCTs); one historically controlled study; and five case series. The majority of the studies were small-scale, heterogeneous and methodologically weak. In four of the studies HBO₂therapy was combined with other treatment modalities, making it impossible to draw firm conclusions on the specific effects of HBO₂therapy. Hip survivorship in studies wherein HBO₂therapy was used alone was 95.5% in Steinberg Stage I lesions, 89% in Steinberg Stage II lesions and 100% in Ficat Stage II lesions. There is a room for HBO₂therapy in the management ONFH. Further RCTs, however, are required to better elucidate the role of HBO₂therapy in the treatment of ONFH.

    Individuals with diabetes are increasingly seeking pretravel advice, but updated professional recommendations remain scant. We performed a systematic review on diabetes management during air travel to summarize current recommendations, assess supporting evidence, and identify areas of future research. A systematic review of the English literature on diabetes management during air travel was undertaken utilizing PubMed and MEDLINE. Publications regarding general travel advice; adjustment of insulin and noninsulin therapies; and the use of insulin pumps, glucometers and subcutaneous glucose sensors at altitude were included. Gathered information was used to create an updated summary of glucose-lowering medication adjustment during air travel. Sixty-one publications were identified, most providing expert opinion and few offering primary data (47 expert opinion, 2 observational studies, 2 case reports, 10 device studies). General travel advice was uniform, with increasing attention to preflight security. Indications for oral antihyperglycemic therapy adjustments varied. There were few recommendations on contemporary agents and on nonhypoglycemic adverse events. There was little consensus on insulin adjustment protocols, many antedating current insulin formulations. Most publications advocated adjusting insulin pump time settings after arrival; however, there was disagreement on timing and rate adjustments. Glucometers and subcutaneous glucose sensors were reported to be less accurate at altitude, but not to an extent that would preclude their clinical use. Recommendations for diabetes management during air travel vary significantly and are mostly based on expert opinion. Data from systematic investigation on glucose-lowering medication adjustment protocols may support the development of a future consensus statement.

    Vulvovaginitis is the most common cause of gynecological complaints in children and young girls. Some of the factors which cause vulvovaginitis include hypoestrogenism, the anatomical proximity of rectum and delicate vulvar skin and vaginal mucosa. We made a literature search with Pubmed, Medline and Cochrane database from January 2002 to May 2015 in English language using the key words vulvovaginitis, children, clinical, diagnosis and treatment. Vulvovaginitis in girls is usually caused by non-specific factors and hygiene measures, bioyoghurt and avoidance of chemical irritants are generally useful. Weight control if necessary and prevention of voiding dysfunction are effective. Vaginal flora is important in girls and results should be interpreted with clinical features to decide whether an isolated microorganism is part of the normal microflora or is the cause of symptomatic vulvovaginitis. Specific treatment is generally considered in case of a detected pathogen microorganism. Isolation of a sexually transmitted organism requires further investigation. Persistent disease may not always indicate a foreign body but it must be taken into account. Girls and parents are encouraged psychologically in all steps of evaluation, diagnosis and treatment. Probiotics, nanotechnology and petroleum jelly are other important treatment options used in vulvovaginitis. In this review, we present current approach to the presentation and management of vulvovaginitis in childhood. This disorder requires a comprehensive evaluation in all steps of diagnosis, differential diagnosis and treatment.

    The analysis aimed to identify the treatment gaps in current fracture liaison services (FLS) and to provide recommendations for best practice establishment of future FLS across the Asia-Pacific region. The findings emphasize the unmet need for the implementation of new programs and provide recommendations for the refinement of existing ones. The study's objectives were to evaluate fracture liaison service (FLS) programs in the Asia-Pacific region and provide recommendations for establishment of future FLS programs. A systematic literature review (SLR) of Medline, PubMed, EMBASE, and Cochrane Library (2000-2017 inclusive) was performed using the following keywords: osteoporosis, fractures, liaison, and service. Inclusion criteria included the following: patients ≥ 50 years with osteoporosis-related fractures; randomized controlled trials or observational studies with control groups (prospective or retrospective), pre-post, cross-sectional and economic evaluation studies. Success of direct or indirect interventions was assessed based on patients' understanding of risk, bone mineral density assessment, calcium intake, osteoporosis treatment, re-fracture rates, adherence, and mortality, in addition to cost-effectiveness. Overall, 5663 unique citations were identified and the SLR identified 159 publications, reporting 37 studies in Asia-Pacific. These studies revealed the unmet need for public health education, adequate funding, and staff resourcing, along with greater cooperation between departments and physicians. These actions can help to overcome therapeutic inertia with sufficient follow-up to ensure adherence to recommendations and compliance with treatment. The findings also emphasize the importance of primary care physicians continuing to prescribe treatment and ensure service remains convenient. These findings highlight the limited evidence supporting FLS across the Asia-Pacific region, emphasizing the unmet need for new programs and/or refinement of

    Monitoring is a costly requirement when conducting clinical trials. New regulatory guidance encourages the industry to consider alternative monitoring methods to the traditional 100 % source data verification (SDV) approach. The purpose of this literature review is to provide an overview of publications on different monitoring methods and their impact on subject safety data, data integrity, and monitoring cost. The literature search was performed by keyword searches in MEDLINE and hand search of key journals. All publications were reviewed for details on how a monitoring approach impacted subject safety data, data integrity, or monitoring costs. Twenty-two publications were identified. Three publications showed that SDV has some value for detection of not initially reported adverse events and centralized statistical monitoring (CSM) captures atypical trends. Fourteen publications showed little objective evidence of improved data integrity with traditional monitoring such as 100 % SDV and sponsor queries as compared to reduced SDV, CSM, and remote monitoring. Eight publications proposed a potential for significant cost reductions of monitoring by reducing SDV without compromising the validity of the trial results. One hundred percent SDV is not a rational method of ensuring data integrity and subject safety based on the high cost, and this literature review indicates that reduced SDV is a viable monitoring method. Alternative methods of monitoring such as centralized monitoring utilizing statistical tests are promising alternatives but have limitations as stand-alone tools. Reduced SDV combined with a centralized, risk-based approach may be the ideal solution to reduce monitoring costs while improving essential data quality.

    Full Text Available OBJETIVO: Revisar a literatura sobre a perda auditiva associada ao envelhecimento e suas implicações, numa perspectiva atual. REVISÃO DA LITERATURA: Nos estudos realizados no Brasil, a presbiacusia vem sendo apontada como causa mais freqüente da deficiência auditiva em pessoas idosas, implicando em uma dificuldade de compreensão durante a comunicação verbal. Estudos internacionais também mostram alta prevalência da perda auditiva em pessoas idosas. DISCUSSÃO: Segundo pesquisas recentes, à medida que o quantitativo da população idosa vem aumentando, também aumenta a prevalência da presbiacusia que interfere na qualidade de vida do idoso. Mesmo entre os profissionais de saúde, ainda é grande o desconhecimento em relação às vantagens e ganhos que a reeducação auditiva específica para idosos com perda auditiva pode oferecer. CONCLUSÃO: Os artigos aqui analisados mostraram que os serviços de saúde da rede pública, que envolvem médicos e fonoaudiólogos, devem estabelecer diretrizes para o desenvolvimento de programas de diagnóstico, aquisição de aparelhos de amplificação sonora individual e, principalmente, de reeducação auditiva para os idosos portadores de presbiacusia, para que eles possam participar e desfrutar das relações sociais, mantendo uma boa qualidade de vida. Entretanto, no Brasil, os estudos e pesquisas nesta área estão apenas começando.AIM: to review the literature on aging-related hearing loss and its current impacts. LITERATURE REVIEW: In studies carried out in Brazil, presbycusis has been blamed for being the most frequent cause of hearing loss in the elderly, causing verbal communication impairment. International studies also show the high prevalence of hearing loss in the elderly. DISCUSSION: According to recent investigations, as the number of elderly people increase, the prevalence of presbycusis interfering in the life quality of this population also increases.

    Full Text Available Expatriation is a widely studied area of research in work and organizational psychology. After expatriates accomplish their missions in host countries, they return to their countries and this process is called repatriation. Adjustment constitutes a crucial part in repatriation research. In the present literature review, research about repatriation adjustment was reviewed with the aim of defining the whole picture in this phenomenon. Present research was classified on the basis of a theoretical model of repatriation adjustment. Basic frame consisted of antecedents, adjustment, outcomes as main variables and personal characteristics/coping strategies and organizational strategies as moderating variables.

    Digital disruption is a term/phenomenon frequently appearing in innovation management literature. However, no academic consensus exists as to what it entails; conceptual nor theoretical. We use the SLR-method (Structured Literature Review) to investigate digital disruption literature. A SLR......-study conducted in 2017 revealed some useful information on how disruption and digital disruption literature has developed over a specific period. However, this study was less representative of papers addressing digital disruption; which is the in-depth subject of this paper. To accommodate this, we intend...... to conduct a similar SLR-study assembling a body literature having digital disruption as the only common denominator...

    Full Text Available This article reviews the literature on research conducted during the last two decades on traffic noise impacts in India. Road traffic noise studies in India are fewer and restricted only to the metropolitan areas. The studies over the years have also focused on the monitoring, recording, analysis, modeling, and to some extent mapping related themes. Negligible studies are observed in areas of physiological and sleep research exposure-effect context. Most impact studies have been associated with annoyance and attitudinal surveys only. Little scientific literature exists related to effects of traffic noise on human physiology in the Indian context. The findings of this review search and analysis observe that very little studies are available relating to traffic noise and health impacts. All of them are subjective response studies and only a small portion of them quantify the exposure-effect chain and model the noise index with annoyance. The review of papers showed that road traffic noise is a cause for annoyance to a variety of degree among the respondents. A generalization of impacts and meta-analysis was not possible due to variability of the study designs and outputs preferred.

    Revision knee arthroplasty is increasing, and in that case, bone loss management is still a challenging problem. In the last years, the body of literature and interest surrounding porous metal cones has grown, but few systematic evaluations of the existing evidence have been performed. The aim of our systematic review is to collect and critically analyze the available evidence about metal cones in revision knee arthroplasty especially focusing our attention on indications, results, complications, and infection rate of these promising orthopaedic devices. We performed a systematic review of the available English literature, considering the outcomes and the complications of tantalum cones. The combinations of keyword were "porous metal cones", "knee revision", "bone loss", "knee arthroplasty", "periprosthetic joint infection", and "outcome". From the starting 312 papers available, 20 manuscripts were finally included. Only one included study has a control group. The main indication for metal cones is type IIb and III defects according AORI classification. Most of the papers show good clinical and radiological outcomes with low rate of complications. The examined studies provide encouraging clinical and radiological short-to-mid-term outcomes. Clinical studies have shown a low rate of aseptic loosening, intraoperative fractures, infection rate and a lower failure rate than the previous treatment methods. Higher quality papers are needed to draw definitive conclusions about porous metal cones.

    Mitral valve prolapse (MVP) is a common valve abnormality in general population. Despite the general belief of a benign disorder, several articles since the 1980s report sudden cardiac death (SCD) in MVP patients, with a substantial percentage of asymptomatic young individuals. The problem is to detect those patients at increased risk and implement methods that are suitable to prevent cardiac arrest. This review investigates the correlation between MVP and SCD, the understanding of the pathophysiology, the strategies for detecting those at risk and treatment options. A complete literature survey was performed using PubMed database search to gather available information regarding MVP and SCD. A total of 33 studies met selection criteria for inclusion in the review. MVP is an underrated cause of arrhythmic SCD. The subset of patients with malignant MVP who may be at greater risk for SCD is characterized by young women with bileaflet MVP, biphasic or inverted T waves in the inferior leads, and frequent complex ventricular ectopic activity with documented ventricular bigeminy or ventricular tachycardia (VT) and premature ventricular contractions (PVCs) configurations of outflow tract alternating with fascicular origin or papillary muscle. MVP is a common condition in the general population and is often encountered in asymptomatic individuals. The existing literature continues to generate significant controversy regarding the association of MVP with ventricular arrhythmias and SCD. Early echocardiography and cardiac magnetic resonance (CMR) are essential, as is a greater understanding of the potential electrophysiological processes of primary arrhythmogenesis and the evaluation of the genetic substrate.

    Considerable interest in the relationship between biodiversity and disease has recently captured the attention of the research community, with important public policy implications. In particular, malaria in the Amazon region is often cited as an example of how forest conservation can improve public health outcomes. However, despite a growing body of literature and an increased understanding of the relationship between malaria and land use / land cover change (LULC) in Amazonia, contradictions have emerged. While some studies report that deforestation increases malaria risk, others claim the opposite. Assessing malaria risk requires examination of dynamic processes among three main components: (i) the environment (i.e. LULC and landscape transformations), (ii) vector biology (e.g. mosquito species distributions, vector activity and life cycle, plasmodium infection rates), and (iii) human populations (e.g. forest-related activity, host susceptibility, movement patterns). In this paper, we conduct a systematic literature review on malaria risk and deforestation in the Amazon focusing on these three components. We explore key features that are likely to generate these contrasting results using the reviewed articles and our own data from Brazil and Peru, and conclude with suggestions for productive avenues in future research.This article is part of the themed issue 'Conservation, biodiversity and infectious disease: scientific evidence and policy implications'. © 2017 The Authors.

    Development of secondary haemophagocytic lymphohistiocytosis (sHLH) in the context of typhoid fever (TF) is a very rare but serious complication. Description of the first pediatric case of typhoid fever acquired in a non-endemic area complicated by sHLH. A systematic literature review of sHLH in the context of TF was performed with extraction of epidemiological, clinical and laboratory data. The literature search revealed 17 articles (22 patients). Fifteen patients were eligible for data analysis (53.4% children). All patients had fever and pancytopenia. Transaminases and LDH were frequently elevated (46.6%). Salmonella typhi was detected mainly by blood culture (64.3%). All the patients received antibiotics whereas immunomodulation (dexamethasone) was used in two cases. A high suspicion index for this condition is needed even in non-endemic areas. The addition of immunmodulation to standard antimicrobial therapy should be considered in selected cases.

    Precise terminology and definitions are important components of scientific language. Although the terms "hard drugs" and "soft drugs" are used widely by professionals, neither the International Classification of Diseases nor the Diagnostic and Statistical Manual classify psychoactive substances into the categories "hard" and "soft." To analyze the occurrence of the terms "hard drugs" and "soft drugs" in recent scientific literature and to establish the degree of consensus in labeling psychoactive substances as "hard" or "soft." A critical review of scientific papers listed in PubMed and Scopus between 2011 and 2015. Three hundred thirty-four articles were initially identified as potentially relevant for review, 132 of which were included in the final analysis. One hundred twenty-four articles used the term "hard drugs" and 84.7% provided examples of substances considered "hard." Forty-four articles used the term "soft drugs" and 90.9% provided examples of substances considered "soft." Citations of relevant articles supporting categorization as "hard" or "soft" were not given in 90% of the articles. The authors often provided no or only very sparse information on their reasons for considering specific drugs as "hard" or "soft." Although it initially appeared that there is substantial agreement as to which psychoactive substances should be regarded as "hard" and "soft," closer inspection shows that the dividing line is blurred without clear criteria for categorization. At this time, it remains uncertain whether these terms should persist in the scientific literature. We therefore recommend these terms should be avoided or, if used, be clearly and precisely defined.

    In comparison to other transportation modes, riding motorcycle is prone to accidents. Motorcyclists are more exposed to physical injury than the car drivers. Many multi-vehicle motorcycles crashes occur, there is right-of- way violation takes place in which another vehicle turns in fronts of a motorcycle, or a sudden cross of path of an on-coming motorcycle. One main factor which leads to high rate of motorcycle crashes is lack of conspicuity of motorcycles by other road users especially during day time traffic. This paper highlights previous studies on the implementation of motorcycle DRLs, focusing on the efficacy of the DRLs to improve motorcycle conspicuity. This paper reviews the impacts of DRL by motorcyclists on multi-vehicle motorcycle crash. The three categories of effects of motorcycle DRLs were reviewed. All literature, supporting that operating headlights during daytime appears to be an influential and effective approach to reduce rate of collision by improving motorcycle’s conspicuity in traffic. The motorcycle DRLs managed to reduce about 4 to 20% of motorcycle crash risk. This paper also recommends that motorcycle DRLs must be used globally, especially in countries with high motorcycle accidents to improve the safety of the riders as well as their pillion riders.

    In the light of five years after a major accident at the Fukushima Daiichi nuclear power plant it is interesting to make nuclear energy related literature review. There is a number of accidents related reports from all major international institutions (like the IAEA and OECD NEA) and research organizations have drawn conclusions and lessons to learn from this terrible accident. These reports are the result of expert and scientific analyses carried out during these five years and they present ideal sources for both understanding what has happened and what can be learned in order to avoid and mitigate effects of such events in the future. From a wider perspective it is also interesting to analyze the impact on research and development (R and D) activities. This literature review is performed with hope to gain some useful insights from the analysis of the volume and topics in all research activities related to the Fukushima accident and nuclear energy (NE) altogether. This kind of review should at least provide an overview of trends and provide base for better planning of future activities. This paper analyzes the published NE related research of over more than 50 years with focus on three major nuclear accidents (TMI, Chernobyl and Fukushima). It has been performed using Scopus tools and database, and mainly focuses on statistics related to the subjects, countries, keywords and type of publishing. It also analyses how responsive is nuclear energy related R and D regarding the volume and subjects, and how is that research spread among most active countries. Nuclear power accidents influence increase and change of research. Both accidents, Chernobyl and Fukushima had maximum share in all nuclear power related papers at similar yearly level (9 percent in 1991 and 12 percent in 2015 respectively). TMI peaked at the 2.5 percent share in 1982. Engineering is the most frequent subjects for TMI and cumulative NE related publishing. Medicine and environmental science subjects

    As part of the Filtration task EM-31, WP-2.3.6, which is a joint effort between Savannah River National Laboratory (SRNL) and the Pacific Northwest National Laboratory (PNNL), tests were planned to evaluate crossflow filtration in order to the improve the use of existing hardware in the waste treatment plants at both the Department of Energy (DOE) Savannah River Site (SRS) and Hanford Site. These tests included experiments to try different operating conditions and additives, such as filter aids, in order to create a more permeable filter cake and improve the permeate flux. To plan the SRNL tests a literature review was performed to provide information on previous experiments performed by DOE laboratories, and by academia. This report compliments PNNL report (Daniel, et al 2010), and is an attempt to try and capture crossflow filtration work performed in the past that provide a basis for future testing. However, not all sources on crossflow filtration could be reviewed due to the shear volume of information available. In this report various references were examined and a representative group was chosen to present the major factors that affect crossflow filtration. The information summarized in this review contains previous operating conditions studied and their influence on the rate of filtration. Besides operating conditions, other attempted improvements include the use of filter aids, a pre-filtration leaching process, the backpulse system, and various types of filter tubes and filter coatings. The results from past research can be used as a starting point for further experimentation that can result in the improvement in the performance of the crossflow filtration. The literature reviewed in this report indicates how complex the crossflow issues are with the results of some studies appearing to conflict results from other studies. This complexity implies that filtration of mobilized stored waste cannot be explained in a simple generic sense; meaning an empirical

    Full Text Available Bertolotti’s syndrome (BS refers to the possible association between the congenital malformation lumbosacral transitional vertebra (LSTV, and low back pain (LBP. Several treatments have been proposed including steroid injections, resections of the LSTV, laminectomy, and lumbar spinal fusion. The aim of this review was to compare the clinical outcomes in previous trials and case reports for these treatments in patients with LBP and LSTV. A PubMed search was conducted. We included English studies of patients diagnosed with LSTV treated with steroid injection, laminectomy, spinal fusion or resection of the transitional articulation. Of 272 articles reviewed 20 articles met the inclusion criteria. Their level of evidence were graded I–V and the clinical outcomes were evaluated. Only 1 study had high evidence level (II. The remainders were case series (level IV. Only 5 studies used validated clinical outcome measures. A total of 79 patients were reported: 31 received treatment with steroid injections, 33 were treated with surgical resection of the LSTV, 8 received lumbar spinal fusion, and 7 cases were treated with laminectomy. Surgical management seems to improve the patient’s symptoms, especially patients diagnosed with “far out syndrome” treated with laminectomy. Clinical outcomes were more heterogenetic for patient’s treated with steroid injections. The literature regarding BS is sparse and generally with low evidence. Non-surgical management (e.g., steroid injections and surgical intervention could not directly be compared due to lack of standardization in clinical outcome. Generally, surgical management seems to improve patient’s clinical outcome over time, whereas steroid injection only improves the patient’s symptoms temporarily. Further studies with larger sample size and higher evidence are warranted for the clinical guidance in the treatment of BS.

    Cardiac morbidity and mortality are closely related to cardiac volumes and global left ventricular (LV) function, expressed as left ventricular ejection fraction. Accurate assessment of these parameters is required for the prediction of prognosis in individual patients as well as in entire cohorts. The current standard of reference for left ventricular function is analysis by short-axis magnetic resonance imaging. In recent years, major extensive technological improvements have been achieved in computed tomography. The most marked development has been the introduction of the multidetector CT (MDCT), which has significantly improved temporal and spatial resolutions. In order to assess the current status of MDCT for analysis of LV function, the current available literature on this subject was reviewed. The data presented in this review indicate that the global left ventricular functional parameters measured by contemporary multi-detector row systems combined with adequate reconstruction algorithms and post-processing tools show a narrow diagnostic window and are interchangeable with those obtained by MRI

    Introduction Benign metastasizing leiomyoma (BML) is a rare disorder that affects women with a history of uterine leiomyoma, which is found to metastasise within extrauterine sites. The aetiology of BML remains unexplained. Because BML is rare, and most publications contain descriptions of single cases, no statistically determined time relations were found between the primary and secondary surgeries, which may have aetiological implications. Objectives To determine age before BML surgery, age during diagnosis of BML, type of prior surgery, and location of metastasis based on the literature. Methods A systematic review of four databases (Medline/PubMed, Embase, Web of Science, and Cochrane) covering articles published from 1 January 1965 to 10 April 2016. The inclusion criteria were full-text articles in English and articles containing case reports. Articles in languages other than English (39), articles containing incomplete data (14), i.e. no information regarding the time of surgery and/or the site of metastasis, articles bereft of case studies (25), and articles with access only to summaries, without access to the complete text (10) were excluded. Of 321 titles identified, only 126 articles met the aforementioned criteria. Results and conclusions The mean age during primary surgery and BML diagnosis was 38.5 years and 47.3 years, respectively. The most common surgery was total hysterectomy. The most frequent site of metastasis was the lungs; other organs were affected less frequently.The site of metastases and their number were not related to the longer time span between the patient’s initial surgery and occurrence of metastasis. The analysed data, such as the age during primary surgery, age during BML diagnosis, site and type of metastasis, do not provide us a clear answer. Thus, BML pathogenesis is most probably complex in nature and requires further multidirectional research. PMID:28426767

From the literature search (n = 26), the most prevalent features were (1) PHR or Web server synchronization, 18 (69%), (2) insulin and medication recording, 17 (65%), (3) diet recording, 17 (65%), and (4) data export and communication, 16 (62%). Interestingly, although clinical guidelines widely refer to the importance of education, this is missing from the top functionalities in both cases. Conclusions While a wide selection of mobile applications seems to be available for people with diabetes, this study shows there are obvious gaps between the evidence-based recommendations and the functionality used in study interventions or found in online markets. Current results confirm personalized education as an underrepresented feature in diabetes mobile applications. We found no studies evaluating social media concepts in diabetes self-management on mobile devices, and its potential remains largely unexplored. PMID:21979293

  19. Fluorine--a current literature review. An NRC and ATSDR based review of safety standards for exposure to fluorine and fluorides.

    Science.gov (United States)

    Prystupa, Jeff

    2011-02-01

    A review of the literature of the element fluorine and its bonded-form, fluoride, was undertaken. Generally regarded as safe, an expanding body of literature reveals that fluoride's toxicity has been unappreciated, un-scrutinized, and hidden for over 70 years. The context for the literature search and review was an environmental climate-change study, which demonstrated widespread fluoride contamination by smokestack emissions from coal-fired electricity-generating plants. The objective of this review is to educate and inform regarding the ubiquitous presence and harmful nature of this now ever-present corrosive and reactive toxin. Methods include examination of national health agency reviews, primarily the National Research Council (NRC), Agency for Toxic Substances & Disease Registry (ATSDR), standard medical toxicology references, text books, as well as reports and documents from both private and public research as well as consumer-based NGOs. Study criteria were chosen for relevancy to the subject of the toxicity of fluoride. Fluoride is the extreme electron scavenger, the most corrosive of all elements, as well as the most-reactive. Fluoride appears to attack living tissues, via several mechanisms. Fluoride renders strong evidence that it is a non-biological chemical, demonstrating no observed beneficial function or role in organic chemistry, beyond use as a pesticide or insecticide. Fluorine has a strong role to play in industry, having been utilized extensively in metals, plastics, paints, aluminium, steel, and uranium production. Due to its insatiable appetite for calcium, fluorine and fluorides likely represent a form of chemistry that is incompatible with biological tissues and organ system functions. Based on an analysis of the affects of fluoride demonstrated consistently in the literature, safe levels have not been determined nor standardized. Mounting evidence presents conflicting value to its presence in biological settings and applications. Evidence

    Submitted in partial fulfillment for a Master of Science degree at the University of Pittsburgh, School of Health Related Professions, Pittsburgh, PA 1.5213 This review of current literature on cycling biomechanics emphasizes lower extremity muscle actions and joint excursions, seat height, pedal position, pedaling rate, force application, and pedaling symmetry. Guidelines are discussed for optimal seat height, pedal position, and pedaling rate. Force application in the power and recovery phases of cycling and the relationship of force application to pedaling symmetry are discussed. The need for a biomechanical approach to cycling exists since a great deal of the literature is primarily physiologic in nature. The purpose of this review is to make cyclists and their advisors aware of the biomechanics of cycling and guidelines to follow. This approach is also important because cycling is a very common form of exercise prescribed by physical therapists for clinic or home programs. Biomechanical aspects of cycling should be considered by cyclists at any level of participation and by physical therapists in order for goal-oriented, efficient cycling to occur.

    CD147 or EMMPRIN is a member of the immunoglobulin superfamily in humans. It is widely expressed in human tumors and plays a central role in the progression of many cancers by stimulating the secretion of matrix metalloproteinases (MMPs) and cytokines. CD147 regulates cell proliferation, apoptosis, and tumor cell migration, metastasis and differentiation, especially under hypoxic conditions. CD147 is also important to many organ systems. This review will provide a detailed overview of the discovery, characterization, molecular structure, diverse biological functions and regulatory mechanisms of CD147 in human physiological and pathological processes. In particular, recent studies have demonstrated the potential application of CD147 not only as a phenotypic marker of activated regulatory T cells but also as a potential diagnostic marker for early-stage disease. Moreover, CD147 is recognized as an effective therapeutic target for hepatocellular carcinoma (HCC) and other cancers, and exciting clinical progress has been made in HCC treatment using CD147-directed monoclonal antibodies.

    Nucleosides, such as uridine, inosine, guanosine and adenosine, may participate in the regulation of sleep, cognition, memory and nociception, the suppression of seizures, and have also been suggested to play a role in the pathophysiology of some neurodegenerative and neuropsychiatric diseases. Under pathological conditions, levels of nucleosides change extremely in the brain, indicating their participation in the pathophysiology of disorders like Alzheimer's disease, Parkinson's disease and schizophrenia. These findings have resulted in an increasing attention to the roles of nucleosides in the central nervous system. The specific effects of nucleosides depend on the expression of their receptors and transporters in neuronal and glial cells, as well as their extracellular concentrations in the brain. A complex interlinked metabolic network and transporters of nucleosides may balance nucleoside levels in the brain tissue under normal conditions and enable the fine modulation of neuronal and glial processes via nucleoside receptor signaling mechanisms. Brain levels of nucleosides were found to vary when measured in a variety of different brain regions. In addition, nucleoside levels also depend on age and gender. Furthermore, distributions of nucleoside transporters and receptors as well as nucleoside metabolic enzyme activities demonstrate the area, age and gender dependence of the nucleoside system, suggesting different roles of nucleosides in functionally different brain areas. The aim of this review article is to summarize our present knowledge of the area-, age- and gender-dependent distribution of nucleoside levels, nucleoside metabolic enzyme activity, nucleoside receptors and nucleoside transporters in the brain.

    Hepatocellular carcinoma is the most common primary liver cancer and it represents the majority of cancer-related deaths in the world. More than 70% of patients present at an advanced stage, beyond potentially curative options. Ytrrium-90 selective internal radiation therapy (Y90-SIRT) with glass microspheres is rapidly gaining acceptance as a potential therapy for intermediate and advanced stage primary hepatocellular carcinoma and liver metastases. The technique involves delivery of Y90 infused glass microspheres via the hepatic arterial blood flow to the appropriate tumor. The liver tumor receives a highly concentrated radiation dose while sparing the healthy liver parenchyma due to its preferential blood supply from portal venous blood. There are two commercially available devices: TheraSphere® and SIR-Spheres®. Although, Y90-SIRT with glass microspheres improves median survival in patients with intermediate and advanced hepatocellular carcinoma and has the potential to downstage hepatocellular carcinoma so that the selected candidates meet the transplantable criteria, it has not gained widespread acceptance due to the lack of large randomized controlled trials. Currently, there are various clinical trials investigating the use of Y90-SIRT with glass microspheres for treatment of hepatocellular carcinoma and the outcomes of these trials may result in the incorporation of Y90-SIRT with glass microspheres into the treatment guidelines as a standard therapy option for patients with intermediate and advanced stage hepatocellular carcinoma

    Workplace-based assessments (WBAs) are trainee-led formative assessments that measure the highest level of competence of the ability to do a task. So far WBAs are the only available assessment tools to measure performance integrated into practice. Over the years, WBAs have become an integral part of dental foundation and specialty training. The numerous WBAs available can be broadly categorised into three types. The first type involves observation of clinical encounters, for example mini-clinical evaluation exercises; direct observation of procedural skills; and dental evaluation of performance and procedure-based assessments. The second type involves discussion of clinical cases, such as case-based discussions. Finally, the third type includes the mini-peer assessment tool, team assessment of behaviour, 360° assessments and multi-source feedback, and all involve receiving feedback from a combination of colleagues, staff and patients. This article describes the WBAs currently used in postgraduate dental training and explores their strengths, weaknesses, perceived value by trainees and trainers and how these tools can be used in a reliable and valid way.

    1980-01-01

    This paper is a review of methods used for direct and indirect dating of tectonic events. Isotope geochemistry including stable isotopes as well as fission track- dating, fluid inclusion and thermoluminescens techniques have been considered. It has been concluded that an investigation of tectonic (and thermal) events should start with a detailed study of the mineral phases grown in seald fissures as well as minerals from fissure walls. This study should include phase identification, textures as well as mineral chemistry. The information from this study is fundamental for the decision of further investigations. Mineral chemistry including isotopes and fluid inclusion studies will give an essential knowledge about crystallization conditions for fissure minerals concerned. Direct dating using fission tracks as well as radioactive isotopes could be useful for some minerals. Application of thermoluminescens dating on fissure minerals is doubtful. (Auth.)

    The impact of oral cancer and its treatment is well documented; therefore, oral rehabilitation (OH; eg, with prosthetics, osseointegrated implants, etc) can be indicated to restore some level of form, function, and well-being. The purpose of this study was to review the current literature and evaluate the impact of OH on quality of life (QoL) after ablative surgery. A systematic literature search was conducted using EMBASE, MEDLINE, and PsychINFO. The study population was composed of all articles published from 2000 to 2015. To be included, studies had to use validated, specific head and neck QoL measurements (European Organization for Research and Treatment of Cancer QoL Head and Neck Module or University of Washington QoL Questionnaire). Only 8 articles met these inclusion criteria. In this review, OH was the primary predictor variable and QoL was the primary outcome variable. The 8 articles reviewed used a range of designs, including 1 randomized controlled trial, 3 prospective cohort studies, 3 case series, and 1 single-measurement cross-sectional descriptive study. Sample sizes were small (n = 26 to 102), and there was limited randomization and control of intervention and comparator groups. The overall level of evidence was weak. All studies showed a link between OH and QoL, but the results varied in significance (P < .01 to P = .95). Overall, there appears to be improvement in QoL to varying degrees after OH. However, a more systematic use of QoL measurements is needed before any definitive conclusions can be drawn. Crown Copyright © 2016. Published by Elsevier Inc. All rights reserved.

    Full Text Available Merkel cell carcinoma (MCC is a rare and aggressive neuroendocrine tumor of the skin. Fourty-eight patients with MCC were observed at the Rare Hormonal Tumors Group of Cremona Hospital, 15 of these with unknown primary site. Due to rarity of Merkel cell carcinoma, clinical experience is generally limited. Data from our series confirm the current recommendations. Wide surgical excision must be associated with radiotherapy also in early stages in order to avoid local relapse and the rapid progression of disease. In advanced stages chemotherapy is the standard despite the short duration of responses and poor quality of life. The data of our series, characterized by a high demand for second opinion, offer some insight about the real rarity of the tumor, the difficulty of managing of disease in our country secondary to a wrong cultural approach to the problem, the indiscriminate use of molecules unnecessary and often expensive, the lack of protocols, and the presence of guidelines often ignored. This results in very poor survival associated with a very low quality of life, requiring to find the right direction towards a correct management of disease.

    Full Text Available ABSTRACT INTRODUCTION: There is a controversy concerning the terminology and definition of rhinitis in pregnancy. Gestational rhinitis is a relatively common condition, which has drawn increasing interest in recent years due to a possible association with maternal obstructive sleep apnea syndrome (OSAS and unfavorable fetal outcomes. OBJECTIVE: To review the current knowledge on gestacional rhinitis, and to assess its evidence. METHODS: Structured literature search. RESULTS: Gestational rhinitis and rhinitis "during pregnancy" are somewhat similar conditions regarding their physiopathology and treatment, but differ regarding definition and prognosis. Hormonal changes have a presumed etiological role, but knowledge about the physiopathology of gestational rhinitis is still lacking. Management of rhinitis during pregnancy focuses on the minimal intervention required for symptom relief. CONCLUSION: As it has a great impact on maternal quality of life, both the otorhinolaryngologist and the obstetrician must be careful concerning the early diagnosis and treatment of gestational rhinitis, considering the safety of treatment measures and drugs and their current level of evidence.

  7. Use of {sup 99m}Tc 2-methoxyisobutyl isonitrile in minimally invasive radioguided surgery in patients with primary hyperparathyroidism: A narrative review of the current literature

    The use of technetium-99m 2-methoxyisobutyl isonitrile ({sup 99m}Tc MIBI) for assistance in minimally invasive radioguided surgery (MIRS) is growing in popularity as a safe, effective, and proficient technique used for parathyroidectomy in primary hyperparathyroidism (PHPT) treatment. Previously, the preferred treatment for PHPT was bilateral neck exploration (BNE), a very invasive, costly, and lengthy procedure. However, as a large majority (80–85% of cases of PHPT) are attributed to a single parathyroid adenoma (PA), a simpler more direct technique such as MIRS is a far better option. The following article is an exploration of the current literature concerning varied protocols utilizing {sup 99m}Tc MIBI for assistance in MIRS for patients undergoing treatment of PHPT. This technique boasts many advantageous outcomes for patients suffering from PHPT. These include a reduction in cost, operating time, and patient recovery; less evidence of post-surgical hypocalcaemia, less pain, and complications; superior cosmetic results; same-day discharge; and the possibility of local anaesthesia which is particularly beneficial in elderly patients. Better outcomes for patients with deep or ectopic PAs, reduced intra-operative complications, and improved cosmetic outcomes for patients who have previously undergone thyroid and/or parathyroid surgery are also advantageous. Of the literature reviewed it was also found that no patients suffered any major surgical complications such as laryngeal nerve palsy or permanent hypoparathyroidism using {sup 99m}Tc MIBI for assistance in MIRS.

    Full Text Available Introduction: In the dental area preventive actions occur in an attempt to avoid the installation of caries, a disease that has an increased prevalence in the population and which is a Public Health problem. Some resources are used for such, such as: performing early diagnosis and the option for conservative treatments of minimal intervention. The glass ionomer cement (CIV, coming from its beneficial characteristics that meet current trends, is closely related to the precepts of Preventive and Minimally Invasive Dentistry and the new preservative techniques recommended. Objective: The objective of the present article was to carry out a literature review study, to determine the characteristics of CIV that has a prominent role in the Minimally Invasive Dentistry profile. Results: The dentist surgeon must be aware of the classification, according to its composition and physical-chemical nature: conventional ionomers; ionomers reinforced by metals; high viscosity and various types of resin modified glass ionomers to correctly choose the CIV that will be used in their clinical interventions, which should occur based on the properties of the material and its clinical indication. Conclusion: It was concluded that the implementation of preventive techniques with CIV in public health care, tend to minimize curative treatments, concurrently valuing the low complexity dental procedures performed in Primary Care, avoiding referrals for treatment of cases of greater complexity at the level Secondary and tertiary care, saving resources.

    For smoke inhalation injury of a pregnant woman, one must treat two patients and be aware of the potential effects of carbon monoxide (CO) and cyanide (CN) poisoning on both the mother and the fetus. In a pregnant woman, the size and age of the fetus and the degree of poisoning allow for tremendous variability in the toxicity of CO and CN and their respective treatment options. The authors will review a case of a 32-year-old woman who was at 37 weeks of gestation and admitted to the Evans-Haynes Burn Center after a house fire and received hydroxocobalamin (Cyanokit) for suspected CN poisoning. In addition, a review of the literature, current guidelines, and treatment options of inhalation injury during pregnancy will be discussed. The authors will focus only on the toxic components of smoke inhalation injury rather than the mechanical components from heat and particulate damage. Literature review clearly identifies that the treatment of pregnant women with inhalation injury remains a controversial subject. The use of hydroxocobalamin (Cyanokit) as a treatment modality for potential CN poisoning in a pregnant patient has not been reported in the literature. Animal studies have shown that combined CO and CN poisoning are more lethal than either one alone and at lower concentrations. Due to the synergistic effects of CO and CN, and because these two toxins concentrate at even higher levels in the fetus than the mother, the authors will clarify the urgent seriousness of prompt administration of hydroxocobalamin in a pregnant patient with suspected smoke inhalation injury. This case review details the treatment of a 32-year-old woman who was at 36 weeks of gestation on admission to the Evans-Haynes Burn Center. The authors will report her injuries and the course of treatment. Although burned and presenting with concomitant smoke inhalation injury, both the woman and her child fared well with no significant complications due to the smoke inhalation at 6 months of follow

    Attention deficit hyper activity disorder (ADHD) is a developmental disorder, most often diagnosed in childhood, and characterized by hyperactivity and inattention that negatively impacts one's ability to function and fulfill social and personal obligations. Individuals with past history of ADHD may enlist in the military under certain conditions, however the full impact of military training and deployment of later in life ADHD symptoms is unclear. It is of particular interest how military experience may affect ADHD in remission and if such individuals might be at elevated risk for relapse of ADHD symptoms. We performed a systematic review f the available literature including the Department of Defense (DOD) guidelines for both eligibility to enlist and fitness for deployment based on reported history and current symptomatology of ADHD. The after care for veterans with ADHD relapse is inconsistent and presents with number of challenges. We evaluate the DOD policies regarding the implications of ADHD for fitness for military service and post-combat mental health. The full extend of the interaction between pre-existing ADHD and post-combat PTSD are not fully understood. The development of comprehensive and clear algorithms for diagnosing and treating ADHD in the military before and after deployment will have a strong positive impact on the quality of care delivered to soldiers and veterans.

    2017-10-23

    This review focuses on evaluating and identifying gaps in the current literature regarding culturally specific dietary influences for patients with type 2 diabetes. As this topic has previously been examined in African American populations, we chose to focus on four other distinct populations (Hispanic, Middle Eastern, Western Pacific, South Asian). Given the rapid increase in global rates of type 2 diabetes and high rates of diabetes among certain ethnic groups, it is important to understand how culturally adapted strategies in diabetes management have been described in different regions and populations. The specific role of nutrition in controlling diabetes is tied to cultural habits and customs. Variation in cultural practices, including diet, create unique environments in which patients with diabetes must navigate. The role of family, particularly among Hispanics, is crucial to cultural adaptations of diabetes management. Incorporating alternative medicine, namely observed in Chinese and Indian populations, also guided diabetes care strategies. Language barriers, health literacy, and acculturation were all unique factors affecting cultural approaches to diabetes management in these four populations. Understanding such cultural determinants is crucial to addressing diabetes disparities and improving outcomes.

    A great deal of concern is recently being expressed relative to the playing of tackle football by adolescent Canadians. The purpose of this literature review is to try to summarize the important data from the available world literature. Very few Canadian statistics are available. Most of the data comes from United States experience. Tackle football injury is examined from various perspectives: 1. Equipment 2. Mechanisms of injury 3. Types of injury, with some emphasis on epiphyseal injury 4. Prevention 5. Comparison with other sports Although no “hard and fast” conclusion is drawn, the paper tends to show that: 1. Football is dangerous 2. Football is damaging to many body systems 3. Prevention of injury is difficult under present conditions 4. Alternate games, such as soccer and rugby seem to provide the same benefits with less catastrophic injuries

    2014-01-01

    A comprehensive literature review was made of the methods of screening (pepsinogen test, gastrin-17, anti HP, SGD and Endoscopy). The review and descriptive study of the scientific literature related to the subject was conducted in the scientific databases: Pud Med, MD Consult and Medscape, from August 2013 to March 2014. 65 articles were found related to the topic. The review has included 47 items, assigned according to the criteria of inclusion and exclusion. Available methods were defined of high cost, difficult to spread, little sensitive, little specific and invasive. Endoscopy has had limitations of cost, quality, morbidity, mortality and availability. Pepsinogen tests and helicobacter pylori have helped identify the population at risk for later sift with endoscopy; but it is a very sensitive method. Endoscopy is recommended every two years in the population at risk (patients between 50 and 70 years with a family history of gastric cancer, chronic atrophic gastritis, Helicobacter pylori infection, intestinal metaplasia and dysplasia, patients with symptomatology of dyspepsia and with positive pepsinogen test) is a higher method than SGD in cost, sensitivity and specificity similar to invasive level. The training of the endoscopists should be strengthened in early gastric cancer detection since the detection depends on the quality of endoscopy [es

  19. Review Of Plutonium Oxidation Literature

    International Nuclear Information System (INIS)

    Korinko, P.

    2009-01-01

    A brief review of plutonium oxidation literature was conducted. The purpose of the review was to ascertain the effect of oxidation conditions on oxide morphology to support the design and operation of the PDCF direct metal oxidation (DMO) furnace. The interest in the review was due to a new furnace design that resulted in oxide characteristics that are different than those of the original furnace. Very little of the published literature is directly relevant to the DMO furnace operation, which makes assimilation of the literature data with operating conditions and data a convoluted task. The oxidation behavior can be distilled into three regimes, a low temperature regime (RT to 350 C) with a relatively slow oxidation rate that is influenced by moisture, a moderate temperature regime (350-450 C) that is temperature dependent and relies on more or less conventional oxidation growth of a partially protective oxide scale, and high temperature oxidation (> 500 C) where the metal autocatalytically combusts and oxidizes. The particle sizes obtained from these three regimes vary with the finest being from the lowest temperature. It is surmised that the slow growth rate permits significant stress levels to be achieved that help break up the oxides. The intermediate temperatures result in a fairly compact scale that is partially protective and that grows to critical thickness prior to fracturing. The growth rate in this regime may be parabolic or paralinear, depending on the oxidation time and consequently the oxide thickness. The high temperature oxidation is invariant in quiescent or nearly quiescent conditions due to gas blanketing while it accelerates with temperature under flowing conditions. The oxide morphology will generally consist of fine particles ( 250 (micro)m). The particle size ratio is expected to be < 5%, 25%, and 70% for fine, medium and large particles, respectively, for metal temperatures in the 500-600 C range.

    In many parts of the world the provision of psychogeriatric inpatient units (PGUs) remains limited. More units will be required over coming decades given rapid population aging. Medline (1950-2010), psycINFO (1806-2009), EMBASE (1980-2009) and CINAHL (1982-2009) were searched for papers about PGU design. Selected non-peer reviewed literature such as government reports and unpublished academic dissertations were also reviewed. Data were also obtained from the literature related to general adult psychiatry inpatient units where there was limited information from studies of units designed for older people. Over 200 papers were reviewed and 130 were included. There are few good quality studies to guide the design of acute PGUs and much of the existing literature is based on opinion and anecdote or, at best, based on observational studies. Randomized controlled studies comparing different designs and assessing outcomes are virtually non-existent. Several studies have identified violence and trauma resulting from hospitalization as significant problems with current acute PGU care. Despite its limitations the available literature provides useful guidance on how PGU design can optimize patient and staff safety and improve clinical outcomes. There are significant problems with current acute PGUs, and patient mix on existing units is an important issue. Future research should examine patient and staff perceptions of different PGU ward environments, the relationship between ward design and clinical outcomes, the effects of segregating patients with challenging behaviors in dementia and the benefits or otherwise of gender segregation.

Material and methods. We reviewed retrospective and prospective randomized trials using Medline and Elibrary databases. Results. The classification system, prognostic factors, paraneoplastic syndromes and their incidence in patients with thyoma were described. The diagnostic value of computed tomography, magnetic resonance imaging and positron emission tomography was evaluated and the methods of morphologic verification were described. The main attention was paid to multimodality treatment of thymoma, including surgery and intraoperative radiotherapy. Conclusion. Thymoma is a rare tumor. The accumulation of long-term follow-up results prompted the changes in clinical management of thymoma. Predisposition to late recurrence even after radical surgery determined multimodality treatment strategies.

    Full Text Available Plagiarism has repeatedly occurred in Indonesia, resulting in focusing on such academic misbehavior as a “central issue” in Indonesian higher education. One of the issues of addressing plagiarism in higher education is that there is a confusion of defining plagiarism. It seems that Indonesian academics had different perception when defining plagiarism. This article aims at exploring the issue of plagiarism by helping define plagiarism to address confusion among Indonesian academics. This article applies literature review by firs finding relevant articles after identifying databases for literature searching. After the collection of required articles for review, the articles were synthesized before presenting the findings. This study has explored the definition of plagiarism in the context of higher education. This research found that plagiarism is defined in the relation of criminal acts. The huge numbers of discursive features used position plagiaristic acts as an illegal deed. This study also found that cultural backgrounds and exposure to plagiarism were influential in defining plagiarism.

    Science.gov (United States)

    In order to more fully understand data gaps in human exposure and toxicity to tire crumb materials, ATSDR, CPSC and EPA undertook a collaborative effort in the form of a scientific literature review and subsequent gaps analysis. The first objective of the Literature Review and Gap Analysis (LRGA) collaboration was to identify the existing body of literature related specifically to human exposure to tire crumb materials through the use of synthetic turf athletic fields and playgrounds. The second objective was to characterize and summarize the relevant data from the scientific literature. The final objective was to review the summary information and identify data gaps to build on the current understanding of the state-of-the-science and inform the development of specific research efforts that would be most impactful in the near-term. Because of the need for additional information, the U.S. Environmental Protection Agency (EPA), the Centers for Disease Control and Prevention/Agency for Toxic Substances and Disease Registry (ATSDR), and the U.S. Consumer Product Safety Commission (CPSC) launched a multi-agency action plan to study key environmental human health questions. The Federal Research Action Plan includes numerous activities, including research studies (U.S. EPA, 2016). A key objective of the Action Plan is to identify key knowledge gaps.

    Full Text Available Recent fraud scandals involving highly known corporations like Enron, WorldCom, and Xerox have eroded public confidence in financial reporting. At the same time, the auditing profession has suffered a big hit. In this scenario, Continuous Auditing (CA seems to have emerged as a response to recover the credibility of the auditing profession as well as meeting Sarbanes-Oxley (SOX requirements. This study, that adopts an exploratory approach, analyzes the existing literature on this topic. First, we address the concepts, models and implications of CA. After, throughout a search on the journals indexed at the CAPES's Basis, a literature review is conducted. A total of 57 articles were selected. We analyze authorship, affiliation, publications, year and type of research of papers that have addressed CA. Findings evidence that most articles addressing CA are non-empirical and adopt a conceptual approach. Also, there is an increasing tendency of continuous auditing studies. Rutgers University seems to be the World's leading research center on CA. This study aims to contribute to the Accounting Science by evidencing possibilities for research and publication in CA.

    The aim of the study was to report the results of a systematically conducted literature review of empirical studies about healthcare organizations' ethics and management or leadership issues. Electronic databases MEDLINE and CINAHL yielded 909 citations. After a two stage application of the inclusion and exclusion criteria 56 full-text articles were included in the review. No large research programs were identified. Most of the studies were in acute hospital settings from the 1990s onwards. The studies focused on ethical challenges, dilemmas in practice, employee moral distress and ethical climates or environments. Study samples typically consisted of healthcare practitioners, operational, executive and strategic managers. Data collection was mainly by questionnaires or interviews and most of the studies were descriptive, correlational and cross-sectional. There is need to develop conceptual clarity and a theoretical framework around the subject of organizational ethics and the breadth of the contexts and scope of the research needs to be increased. © The Author(s) 2011

    Childhood obesity, with its growing prevalence, detrimental effects on population health and economic burden, is an important public health issue in the United States and worldwide. There is need for expansion of the role of primary care physicians in obesity interventions. The primary aim of this review is to explore primary care physician (PCP) mediated interventions targeting childhood obesity and assess the roles played by physicians in the interventions. A systematic review of the literature published between January 2007 and October 2014 was conducted using a combination of keywords like "childhood obesity", "paediatric obesity", "childhood overweight", "paediatric overweight", "primary care physician", "primary care settings", "healthcare teams", and "community resources" from MEDLINE and CINAHL during November 2014. Author name(s), publication year, sample size, patient's age, study and follow-up duration, intervention components, role of PCP, members of the healthcare team, and outcomes were extracted for this review. Nine studies were included in the review. PCP-mediated interventions were composed of behavioural, education and technological interventions or a combination of these. Most interventions led to positive changes in Body Mass Index (BMI), healthier lifestyles and increased satisfaction among parents. PCPs participated in screening and diagnosing, making referrals for intervention, providing nutrition counselling, and promoting physical activity. PCPs, Dietitians and nurses were often part of the healthcare team. PCP-mediated interventions have the potential to effectively curb childhood obesity. However, there is a further need for training of PCPs, and explain new types of interventions such as the use of technology. Copyright © 2015 Asia Oceania Association for the Study of Obesity.

  16. Electroconvulsive Therapy: A Current Review

    Directory of Open Access Journals (Sweden)

    Gokben Hizli Sayar

    2014-06-01

    Full Text Available Most of the electroconvulsive therapy guidelines state that severe major depression with psychotic features, manic delirium, or catatonia are conditions where there is a clear consensus favoring early electroconvulsive therapy. The decision to administer electroconvulsive therapy is based on an evaluation of the risks and benefits for the individual patient and involves a combination of factors, including psychiatric diagnosis, type and severity of symptoms, prior treatment history and response, identification of possible alternative treatment options, and consumer preference. In this review history, mechanisms of action, side effects that have been referenced in the literature and clinical experience are discussed.

    2009-01-01

    Laparoscopic pancreatic surgery represents one of the most advanced applications for laparoscopic surgery currently in use. In the past, minimally invasive techniques were only used for diagnostic laparoscopy, staging of pancreatic cancer, and palliative procedures for unresectable pancreatic cancer. With new advances in technology and instrumentation, some sophisticated procedures are currently available, such as the Whipple procedure, one of the most sophisticated applications of minimally invasive surgery. A review of the literature shows that 146 laparoscopic Whipple procedures have been published worldwide since 1994. The authors analyzed blood loss, mean operating time, hospital stay, conversion rate, mean age, mortality rate, lymph nodes in the pathologic findings, follow up, and complications. Mean age was 59.1 years; mean operating time was 439 min. The average blood loss for the reviewed literature was 143 mL; median hospital stay was 18 days; conversion rate was 46%; number of lymph nodes in the pathologic findings was 19; and mortalities related to the procedure was low, 2 patients (1.3%) and the complication rate was 16% (23/46 patients). Complications included 2 hemorrhages, 4 bowel obstructions, 1 stress ulcer, 1 delay of gastric emptying, 4 pneumonias, and 11 leaks. This review demonstrates that the laparoscopic Whipple procedure is not only feasible but also safe, with low mortality and acceptable rates of complications.

    This article examines how to synthesise and critique research literature. To place the process of synthesising the research literature into context, the article explores the critiquing process by breaking it down into seven sequential steps. The article explains how and why these steps need to be kept in mind if a robust comprehensive literature search and analysis are to be achieved. The article outlines how to engage in the critiquing process and explains how the literature review needs to be assembled to generate a logical and reasoned debate to examine a topic of interest or research in more detail.

    Full Text Available Sickle cell disease (SCD is an autosomal recessive hemoglobinopathy that causes significant morbidity and mortality related to chronic hemolytic anemia, vaso-occlusion, and resultant end-organ damage. Tobacco smoke exposure (TSE through secondhand smoke exposure in people with SCD of all ages and through primary smoking in adolescents and adults is associated with significantly increased morbidity, with increased rates of emergency department visits and hospitalizations for painful vaso-occlusive crises and acute chest syndrome (ACS. Secondhand smoke is also associated with pulmonary function abnormalities in children with SCD who are already at risk for pulmonary function abnormalities on the basis of SCD. TSE is emerging as one of the few modifiable risk factors of SCD. This review discusses the current state of the evidence with respect to TSE and SCD morbidity, discusses potential mechanisms, and highlights current gaps in the evidence and future research directions.

    Since their introduction in 1991, propeller flaps are increasingly used as a surgical approach to loss of substance. The aim of this study was to evaluate the indications and to verify the outcomes and the complication rates using this reconstructing technique through a literature review. A search on PubMed was performed using "propeller flap", "fasciocutaneous flap", "local flap" or "pedicled flap" as key words. We selected clinical studies using propeller flaps as a reconstructing technique. We found 119 studies from 1991 to 2015. Overall, 1,315 propeller flaps were reported in 1,242 patients. Most frequent indications included loss of substance following tumor excision, repair of trauma-induced injuries, burn scar contractures, pressure sores and chronic infections. Complications were observed in 281/1242 patients (22.6%) occurring more frequently in the lower limbs (31.8%). Partial flap necrosis and venous congestion were the most frequent complications. The complications' rate was significantly higher in infants (70 years old) but there was not a significant difference between the sexes. Trend of complication rate has not improved during the last years. Propeller flaps showed a great success rate with low morbidity, quick recovery, good aesthetic outcomes and reduced cost. The quality and volume of the transferred soft tissue, the scar orientation and the possibility of direct donor site closure should be considered in order to avoid complications. Indications for propeller flaps are small- or medium-sized defects located in a well-vascularized area with healthy surrounding tissues.

    Patient aggression is a longstanding problem in general hospital nursing. Staff training is recommended to tackle workplace aggression originating from patients or visitors, yet evidence on training effects is scarce. To review and collate current research evidence on the effect of aggression management training for nurses and nursing students working in general hospitals, and to derive recommendations for further research. Systematic, narrative review. Embase, MEDLINE, the Cochrane library, CINAHL, PsycINFO, pubmed, psycArticles, Psychology and Behavioural Sciences Collection were searched for articles evaluating training programs for staff and students in acute hospital adult nursing in a 'before/after' design. Studies published between January 2000 and September 2011 in English, French or German were eligible of inclusion. The methodological quality of included studies was assessed with the 'Quality Assessment Tool for Quantitative Studies'. Main outcomes i.e. attitudes, confidence, skills and knowledge were collated. Nine studies were included. Two had a weak, six a moderate, and one a strong study design. All studies reported increased confidence, improved attitude, skills, and knowledge about risk factors post training. There was no significant change in incidence of patient aggression. Our findings corroborate findings of reviews on training in mental health care, which point to a lack of high quality research. Training does not reduce the incidence of aggressive acts. Aggression needs to be tackled at an organizational level. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available Elena Olariu,1 Kevin K Cadwell,1 Elizabeth Hancock,1 David Trueman,1 Helene Chevrou-Severac2 1PHMR Ltd, London, UK; 2Takeda Pharmaceuticals International AG, Zurich, Switzerland Objective: Although Markov cohort models represent one of the most common forms of decision-analytic models used in health care decision-making, correct implementation of such models requires reliable estimation of transition probabilities. This study sought to identify consensus statements or guidelines that detail how such transition probability matrices should be estimated. Methods: A literature review was performed to identify relevant publications in the following databases: Medline, Embase, the Cochrane Library, and PubMed. Electronic searches were supplemented by manual-searches of health technology assessment (HTA websites in Australia, Belgium, Canada, France, Germany, Ireland, Norway, Portugal, Sweden, and the UK. One reviewer assessed studies for eligibility. Results: Of the 1,931 citations identified in the electronic searches, no studies met the inclusion criteria for full-text review, and no guidelines on transition probabilities in Markov models were identified. Manual-searching of the websites of HTA agencies identified ten guidelines on economic evaluations (Australia, Belgium, Canada, France, Germany, Ireland, Norway, Portugal, Sweden, and UK. All identified guidelines provided general guidance on how to develop economic models, but none provided guidance on the calculation of transition probabilities. One relevant publication was identified following review of the reference lists of HTA agency guidelines: the International Society for Pharmacoeconomics and Outcomes Research taskforce guidance. This provided limited guidance on the use of rates and probabilities. Conclusions: There is limited formal guidance available on the estimation of transition probabilities for use in decision-analytic models. Given the increasing importance of cost

    Full Text Available The global primary literature on Zika virus (ZIKV (n = 233 studies and reports, up to March 1, 2016 has been compiled using a scoping review methodology to systematically identify and characterise the literature underpinning this broad topic using methods that are documented, updateable and reproducible. Our results indicate that more than half the primary literature on ZIKV has been published since 2011. The articles mainly covered three topic categories: epidemiology of ZIKV (surveillance and outbreak investigations 56.6% (132/233, pathogenesis of ZIKV (case symptoms/ outcomes and diagnosis 38.2% (89/233 and ZIKV studies (molecular characterisation and in vitro evaluation of the virus 18.5% (43/233. There has been little reported in the primary literature on ZIKV vectors (12/233, surveillance for ZIKV (13/233, diagnostic tests (12/233 and transmission (10/233. Three papers reported on ZIKV prevention/control strategies, one investigated knowledge and attitudes of health professionals and two vector mapping studies were reported. The majority of studies used observational study designs, 89.7% (209/233, of which 62/233 were case studies or case series, while fewer (24/233 used experimental study designs. Several knowledge gaps were identified by this review with respect to ZIKV epidemiology, the importance of potential non-human primates and other hosts in the transmission cycle, the burden of disease in humans, and complications related to human infection with ZIKV. Historically there has been little research on ZIKV; however, given its current spread through Australasia and the Americas, research resources are now being allocated to close many of the knowledge gaps identified in this scoping review. Future updates of this project will probably demonstrate enhanced evidence and understanding of ZIKV and its impact on public health.

    Knowledge discovery in biomedicine is a time-consuming process starting from the basic research, through preclinical testing, towards possible clinical applications. Crossing of conceptual boundaries is often needed for groundbreaking biomedical research that generates highly inventive discoveries. We demonstrate the ability of a creative literature mining method to advance valuable new discoveries based on rare ideas from existing literature. When emerging ideas from scientific literature are put together as fragments of knowledge in a systematic way, they may lead to original, sometimes surprising, research findings. If enough scientific evidence is already published for the association of such findings, they can be considered as scientific hypotheses. In this chapter, we describe a method for the computer-aided generation of such hypotheses based on the existing scientific literature. Our literature-based discovery of NF-kappaB with its possible connections to autism was recently approved by scientific community, which confirms the ability of our literature mining methodology to accelerate future discoveries based on rare ideas from existing literature.

    Compassion is elemental in the care of a patient during their medical imaging (MI) procedure and is highly topical in the light of the Francis Report. The patient–practitioner interaction is an amalgam of context, communication and individual differences, and whilst compassion is a term in common parlance in the media, policy and radiographers' professional documents, its meaning and manifestation in radiography recruitment, education and practice are less clearly articulated. A review of the existing literature was undertaken, including a small scale study exploring patients' experiences in diagnostic medical imaging. Themes from the study included communication; competence; emotions; attitudes and relationships, but notably absent was any mention of compassion per se. Radiography research would benefit from further exploratory work into the nature of compassionate patient care in the unique context of the medical imaging encounter; offering an evidence-based contribution to radiography in the light of the Francis Report. - Highlights: • An increased focus on compassion was recommended in the Francis Report. • Best compassionate care is a requirement in radiographers' Code of Professional Conduct. • The meaning of compassionate patient care in radiography is not well understood. • Equally neither is the expression of compassion in radiography. • Research into compassion will contribute to evidence-based practice in radiography.

    The purpose of this review was to summarize recent developments regarding photodynamic therapy (PDT) in the field of dentistry. A review of pertinent literature was carried out in PubMED to determine the current position of PDT applications in dentistry. One hundred thirteen relevant articles were retrieved from PubMED by inserting the keywords "photodynamic therapy", "dentistry", "periodontology", "oral surgery", and "endodontics". It is anticipated that this overview will create a specific picture in the practitioner's mind regarding the current status and use of PDT. In spite of different results and suggestions brought about by different researchers, PDT can be considered as a promising and less invasive technique in dentistry. PDT seems to be an effective tool in the treatment of localized and superficial infections. Within the limitations of the present review, it can be concluded that although PDT cannot replace antimicrobial therapy at its current stage, it may be used as an adjunctive tool for facilitating the treatment of oral infections. Oral infections (such as mucosal and endodontic infections, periodontal diseases, caries, and peri-implantitis) are among the specific targets where PDT can be applied. Further long-term clinical studies are necessary in establishing a more specific place of the technique in the field of dentistry.

    Full Text Available Obesity has currently reached epidemic proportions, both in Chile and in the world. This condition is associated to a variety of maternal complications in all stages of the vital cycle and during pregnancy. Medical treatment has not proved successful thus resulting in an increase in bariatric surgery in recent years, even when it is not first line treatment. This literature review aims to report updated results of surgical treatment for obesity before and during pregnancy with respect to fertility, gestational diabetes, pre-eclampsia and pregnancy-induced hypertension. It also looks into the possible effects of surgery on fetal development, and its relation to premature delivery, fetal macrosomy, low birth weight and neural tube defects, as well as effects on maternal and fetal outcomes, mainly in nutrition. Lastly, we suggest some recommendations that arise from this review on the role of contraception, nutrition and time between surgery and pregnancy.

    Recently, several in vitro and in vivo studies demonstrated promising results about the use of photodynamic therapy during root canal system disinfection. However, there is no consensus on a standard protocol for its incorporation during root canal treatment. The purpose of this study was to summarize the results of research on photodynamic therapy in endodontics published in peer-reviewed journals. A review of pertinent literature was conducted using the PubMed database, and data obtained were categorized into sections in terms of relevant topics. Studies conducted in recent years highlighted the antimicrobial potential of photodynamic therapy in endodontics. However, most of these studies were not able to confirm a significant improvement in root canal disinfection for photodynamic therapy as a substitute for current disinfection methods. Its indication as an excellent adjunct to conventional endodontic therapy is well documented, however. Data suggest the need for protocol adjustments or new photosensitizer formulations to enhance photodynamic therapy predictability in endodontics.

    Elizabeth Smythe PhD, RN, RM

    2012-02-01

    Full Text Available In academia there seems to be a taken for granted assumption that there is one way to do a literature review. This paper argues that the manner of reviewing literature needs to be congruent with the particular research methodology. As an example, the authors explicate reviewing literature in hermeneutic research. The paper begins by discussing philosophical assumptions. The authors then offer personal accounts of their experiences of working with literature in ways that are congruent with hermeneutic methodology. It is argued that the key purpose of exploring literature in hermeneutic research is to provide context and provoke thinking. Literature, which can include anything that provokes thinking on the phenomenon of interest, becomes an essential dialogical partner from which scholarly thinking and new insights emerge. In conclusion distinguishing hallmarks of ways of working hermeneutically with literature are articulated

    2010-01-01

    The review makes a brief overview of traditional methods of measurement of electric current and shows in more detail relatively new types of current sensors. These include Hall sensors with field concentrators, AMR current sensors, magneto-optical and superconducting current sensors. The influence of the magnetic core properties on the error of the current transformer shows why nanocrystalline materials are so advantageous for this application. Built-in CMOS current sensors are important tools for monitoring the health of integrated circuits. Of special industrial value are current clamps which can be installed without breaking the measured conductor. Parameters of current sensors are also discussed, including geometrical selectivity. This parameter specific for current sensors means the ability to suppress the influence of currents external to the sensor (including the position of the return conductor) and also suppress the influence on the position of the measured conductor with respect to the current.

    Our review of real-time three-dimensional echocardiography (RT3DE) discusses the diagnostic utility of RT3DE and provides a comparison with two-dimensional echocardiography (2DE) in clinical cardiology. A Pubmed literature search on RT3DE was performed using the following key words: transthoracic, two-dimensional, three-dimensional, real-time, and left ventricular (LV) function. Articles included perspective clinical studies and meta-analyses in the English language, and focused on the role of RT3DE in human subjects. Application of RT3DE includes analysis of the pericardium, right ventricular (RV) and LV cavities, wall motion, valvular disease, great vessels, congenital anomalies, and traumatic injury, such as myocardial contusion. RT3DE, through a transthoracic echocardiography (TTE), allows for increasingly accurate volume and valve motion assessment, estimated LV ejection fraction, and volume measurements. Chamber motion and LV mass approximation have been more accurately evaluated by RT3DE by improved inclusion of the third dimension and quantification of volumetric movement. Moreover, RT3DE was shown to have no statistical significance when comparing the ejection fractions of RT3DE to cardiac magnetic resonance (CMR). Analysis of RT3DE data sets of the LV endocardial exterior allows for the volume to be directly quantified for specific phases of the cardiac cycle, ranging from end systole to end diastole, eliminating error from wall motion abnormalities and asymmetrical left ventricles. RT3DE through TTE measures cardiac function with superior diagnostic accuracy in predicting LV mass, systolic function, along with LV and RV volume when compared with 2DE with comparable results to CMR.

    2013-03-01

    Workplace safety has been historically neglected by organizations in order to enhance profitability. Over the past 30 years, safety concerns and attention to safety have increased due to a series of disastrous events occurring across many different industries (e.g., Chernobyl, Upper Big-Branch Mine, Davis-Besse etc.). Many organizations have focused on promoting a healthy safety culture as a way to understand past incidents, and to prevent future disasters. There is an extensive academic literature devoted to safety culture, and the Department of Energy has also published a significant number of documents related to safety culture. The purpose of the current endeavor was to conduct a review of the safety culture literature in order to understand definitions, methodologies, models, and successful interventions for improving safety culture. After reviewing the literature, we observed four emerging themes. First, it was apparent that although safety culture is a valuable construct, it has some inherent weaknesses. For example, there is no common definition of safety culture and no standard way for assessing the construct. Second, it is apparent that researchers know how to measure particular components of safety culture, with specific focus on individual and organizational factors. Such existing methodologies can be leveraged for future assessments. Third, based on the published literature, the relationship between safety culture and performance is tenuous at best. There are few empirical studies that examine the relationship between safety culture and safety performance metrics. Further, most of these studies do not include a description of the implementation of interventions to improve safety culture, or do not measure the effect of these interventions on safety culture or performance. Fourth, safety culture is best viewed as a dynamic, multi-faceted overall system composed of individual, engineered and organizational models. By addressing all three components of

    To evaluate the stone-free rates (SFRs) and stone clearance rates (SCRs) of extracorporeal shock-wave lithotripsy (SWL), retrograde intrarenal surgery (RIRS), and percutaneous nephrolitholapaxy (PCNL) according to non-contrast computer tomography (NCCT) findings. Original articles were identified from PubMed. After exclusion of ineligible papers, twenty-three studies with 2494 cases were included in the review. Six SWL, five RIRS and eight PCNL studies were selected. Additionally, four comparative articles were identified. SWL presents SFRs ranging 35-61.3 % and SCRs for residuals <4 mm being 43.2-92.9 %. RIRS studies report SFRs of 34.8-59.7 % and SCRs for residuals <4 mm ranging 48-96.7 %. Finally, PCNL presents SFRs of 20.8-100 % and SCRs for residuals <4 mm being 41.5-91.4 %. According to the comparative studies, SFRs are 17-61.3 % for SWL, 50 % for RIRS, and 95-100 % for PCNL. According to NCCT findings, it seems that PCNL provides better SFRs than ESWL and RIRS. However, further research with comparable and complete preoperative parameters and outcomes could reduce the heterogeneity of current data.

    Full Text Available Objective: The objective of this paper is to provide an overview of the state-of-the-art in research on entrepreneurial mindset (EM. The paper identifies research areas which have contributed to the current status of the EM concept, outlines areas which remain under-addressed and suggests areas for future research. Research Design & Methods: A comprehensive method of a synthetic literature review was employed. In a four-step process, relevant papers were identified and classified. Research methods and sampling were analysed and put into a perspective of the EM concept development. Based on that, recommendations for future research are presented. Findings: No commonly shared EM concept was found. Instead, scholars have contributed largely by depicting particular attributes of EM. These attributes can be divided into core attributes of EM and meta-cognitive attributes of EM. While core attributes are easier to recognize and exhibited through behaviour, meta-cognitive attributes are more hidden within an individual. Mainly the Anglo-American perspective influences the research on EM. The dominating research design methods remain quantitative. Only one longitudinal and one qualitative study using in-depth interviews were identified in the pool. Links to other research areas are provided. Implications & Recommendations: The EM concept might be investigated further with the inclusion of more other cultures or with people from other cultural backgrounds to test the validity of the existing assumptions. Contribution & Value Added: This literature review contributes to the current body of knowledge by giving an overview of the EM concept and its attributes and associated qualities. It identifies current gaps in research and provides recommendations on how to close them.

  1. Is there an empirical link between impulsivity and suicidality in bipolar disorders? A review of the current literature and the potential psychological implications of the relationship.

    Suicide is highly prevalent among individuals with bipolar disorder and understanding the factors that increase risk for suicide may help to develop targeted interventions to prevent attempts. Impulsivity is thought to be an influential factor associated with suicidality and is also discussed as a key construct of bipolar disorder. The aim of this paper was to systematically review the current evidence to examine the association between impulsivity and suicidality in bipolar disorder. PsycInfo, Medline, and Web of Knowledge databases were searched for articles published up until March 2012. Papers were included if they assessed an adult sample of individuals with bipolar disorders, focused on suicidality (ideation with intent to die, suicide attempts, or completion), and used a validated measure to determine impulsivity. Sixteen papers were identified. Contrary to widespread belief, we found (i) a very inconsistent picture of results including positive, negative, and insignificant associations between impulsivity and suicidality; and (ii) some studies do not take into account important aspects such as state-trait or measurement issues. The link between suicidality and impulsivity is less straightforward than often assumed. Drawing clear conclusions about the association is hampered by factors such as inconsistencies in defining suicidality, measuring impulsivity, and differentiating between impulsivity as a personality trait and impulsivity as a state (e.g., a consequence of substance use or premeditation of the attempt). We suggest that the association is less direct and that psychological models (e.g., Joiner's theory of suicidality) can help foster a more in-depth understanding regarding the relationship. © 2013 John Wiley & Sons A/S.

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

  3. Cyanotic Congenital Heart Defects – literature review

    Full Text Available Congenital heart defects are one of the most interesting and important chapters regarding abnormal fetal growth pathology. The objective of this article is to present a literature review for the main cyanotic congenital heart defects. The ones presented in the article are: tetralogy of Fallot, transposition of the great vessels, double outlet right ventricle, truncus arteriosus, total anomalous pulmonary venous circulation and additional information regarding very rare malformations such as pentalogy of Cantrell and Uhl anomaly. An early and precise identification of congenital heart defects is an important step in an accurate follow-up of a potential problematic pregnancy. Knowing the sonographic aspect, associated pathology and the current available treatment procedures are vital for the fetal outcome and for the physician to adapt the right management in every situation that might appear during the pregnancy and in the neonatal period.

    Microgrids are an increasingly common component of the evolving electricity grids with the potential to improve local reliability, reduce costs, and increase penetration rates for distributed renewable generation. The additional complexity of microgrids often leads to increased investment costs, creating a barrier for widespread adoption. These costs may result directly from specific needs for islanding detection, protection systems and power quality assurance that would otherwise be avoided in simpler system configurations. However, microgrids also facilitate additional value streams that may make up for their increased costs and improve the economic viability of microgrid deployment. This paper analyses the literature currently available on research relevant to value streams occurring in microgrids that may contribute to offset the increased investment costs. A review on research related to specific microgrid requirements is also presented.

    Mozart ear is a congenital auricular deformity, which is mainly characterized by a bulging appearance of the anterosuperior portion of the auricle, a convexly protruded cavum conchae, and a slit-like narrowing of the orifice of the external auditory meatus. It is said to be uncommon, and because no one has yet fully described neither the disease nor the treatment, the concept of Mozart ear has not been unified. This report describes a case of a 13-year-old girl presented with an unusual congenital deformity which showed the features of Mozart ear. It is an extremely rare deformity that only about 4 clinical cases have been reported in medical literature thereby a treatment method has not been fully discussed. For surgical correction of our cases, we excised deformed conchal cartilage, turned it over, regrafted, and maintained a cosmetically positive result. We also reviewed and described the origin, current concept, and treatment method of Mozart ear.

  6. Mineralization of Carbon Dioxide: Literature Review

    Energy Technology Data Exchange (ETDEWEB)

    Romanov, V; Soong, Y; Carney, C; Rush, G; Nielsen, B; O' Connor, W

    2015-01-01

    CCS research has been focused on CO2 storage in geologic formations, with many potential risks. An alternative to conventional geologic storage is carbon mineralization, where CO2 is reacted with metal cations to form carbonate minerals. Mineralization methods can be broadly divided into two categories: in situ and ex situ. In situ mineralization, or mineral trapping, is a component of underground geologic sequestration, in which a portion of the injected CO2 reacts with alkaline rock present in the target formation to form solid carbonate species. In ex situ mineralization, the carbonation reaction occurs above ground, within a separate reactor or industrial process. This literature review is meant to provide an update on the current status of research on CO2 mineralization. 2

    2017-01-01

    To inform radiologic technologists about which imaging modalities and examinations are best suited for evaluating specific anatomical structures in patients who have sustained a traumatic injury. Two scholarly research databases were searched to identify articles focused on trauma imaging of the head, cervical spine, thorax, abdomen, and pelvis. Articles focused on trauma diagnosis were excluded. Thirty-two articles were selected for analysis. Physical examination and plain-film radiographs typically are used to assess nasal bone fracures. Computed tomography (CT) can be used to assess zygomaticomaxillary complex, mandibular, and temporal bone fractures. Traumatic brain injuries are difficult to assess, and broad classifications are used. Depending on the severity of cervical spine trauma, plain-film radiographs or CT imaging is adequate, with magnetic resonance imaging used as a means for further evaluation. Trauma to the thorax typically is assessed with radiography and CT, and CT is recommended for assesment of abdominal and pelvic trauma. The literature was consistent regarding which examinations to perform to best evaluate suspected injuries to the chest, abdomen, and pelvis. The need for, and correct use of, imaging in evaluating trauma to the head and cervical spine is more controversial. Despite the need for additional research, emergency department care providers should be familiar with the structures most commonly injured during trauma and the role of medical imaging for diagnosis.

    Several studies have shown that both children and adults benefit substantially from access to a means of independent mobility. While the needs of many individuals with disabilities can be satisfied with traditional manual or powered wheelchairs, a segment of the disabled community finds it difficult or impossible to use wheelchairs independently. To accommodate this population, researchers have used technologies originally developed for mobile robots to create "smart wheelchairs." Smart wheelchairs have been the subject of research since the early 1980s and have been developed on four continents. This article presents a summary of the current state of the art and directions for future research.

    Full Text Available Nowadays the customer requirements are in permanent changing and according with them the tendencies in the modern industry is to implement flexible manufacturing processes. In the last decades, metal forming gained attention of the researchers and considerable changes has occurred. Because for a small number of parts, the conventional metal forming processes are expensive and time-consuming in terms of designing and manufacturing preparation, the manufacturers and researchers became interested in flexible processes. One of the most investigated flexible processes in metal forming is incremental sheet forming (ISF. ISF is an advanced flexible manufacturing process which allows to manufacture complex 3D products without expensive dedicated tools. In most of the cases it is needed for an ISF process the following: a simple tool, a fixing device for sheet metal blank and a universal CNC machine. Using this process it can be manufactured axis-symmetric parts, usually using a CNC lathe but also complex asymmetrical parts using CNC milling machines, robots or dedicated equipment. This paper aim to present the current status of incremental sheet forming technologies in terms of process parameters and their influences, wall thickness distribution, springback effect, formability, surface quality and the current main research directions.

    2015-04-01

    It is not known what constitutes the optimal emergency management system, nor is there a consensus on how effectiveness and efficiency in emergency response should be measured or evaluated. Literature on the role and tasks of commanders in the prehospital emergency services in the setting of mass-casualty incidents has not been summarized and published. This comprehensive literature review addresses some of the needs for future research in emergency management through three research questions: (1) What are the basic assumptions underlying incident command systems (ICSs)? (2) What are the tasks of ambulance and medical commanders in the field? And (3) How can field commanders' performances be measured and assessed? A systematic literature search in MEDLINE, PubMed, PsycINFO, Embase, Cochrane Central Register of Controlled Trials, Cochrane Library, ISI Web of Science, Scopus, International Security & Counter Terrorism Reference Center, Current Controlled Trials, and PROSPERO covering January 1, 1990 through March 1, 2014 was conducted. Reference lists of included literature were hand searched. Included papers were analyzed using Framework synthesis. The literature search identified 6,049 unique records, of which, 76 articles and books where included in qualitative synthesis. Most ICSs are described commonly as hierarchical, bureaucratic, and based on military principles. These assumptions are contested strongly, as is the applicability of such systems. Linking of the chains of command in cooperating agencies is a basic difficulty. Incident command systems are flexible in the sense that the organization may be expanded as needed. Commanders may command by direction, by planning, or by influence. Commanders' tasks may be summarized as: conducting scene assessment, developing an action plan, distributing resources, monitoring operations, and making decisions. There is considerable variation between authors in nomenclature and what tasks are included or highlighted

    2014-01-01

    Mantle cell lymphoma (MCL) is a distinct subtype of lymphoma identified as a particular entity in the early 1990s. The prognosis of MCL is generally poor, and is considered one of the worst among all B-cell lymphomas. In general, conventional chemotherapy is only palliative and the median duration of remissions is only 1-2 years. With the exception of allogeneic hematopoietic stem cell transplantation (allo-SCT), current treatment approaches are not curative and the corresponding survival curve is characterized by a relatively steep and continuous decline, with a median survival of about 4 years and watch and wait strategy. Optimal first-line therapy in MCL is not established yet. Very intensive regimens, including autologous (auto-SCT) and allo-SCT, seem to be required to improve the outcome. Allogeneic stem cell transplantation is the only therapy that can achieve a plateau in the survival curve, but, however, it is not applicable in most of the cases due to the patients' older age when the disease mostly occurs. Molecular knowledge of MCL has progressed and therefore a large number of molecular targeted therapies have been introduced in relapsed and refractory disease.

    2014-01-01

    Full Text Available Carcinosarcoma of the uterus is a rare gynaecological neoplasm, which is also known as malignant mixed mesodermal tumor. Traditionally this tumour has been regarded as a subtype of uterine sarcoma, and its origin remains controversial. The exact nature and prognosis was not clear in the past. It is believed that uterine carcinosarcoma have a Mullerian duct origin and have a capacity to differentiate into various mesenchymal and epithelial components. Regarding the histogensis, various theories have been given; of which ′conversion theory′ was broadly accepted. Carcinosarcoma are mostly of monoclonal origin with the carcinomatous component being the driving force. This type of tumor is broadly divided into two groups, homologous and heterologous, depending on the characteristics of the stroma or mesenchymal components of endometrial tissue. It is more frequent in black women and postmenopausal women. Radiation is a possible etiological factor but the exact etiology is not known yet. However, tamoxifen may induce carcinogenesis in some patients. Its clinical feature is very similar to endometrial carcinoma i.e. postmenopausal vaginal bleeding, have a very aggressive behavior and a poor prognosis. This pelvic malignancy is treated by multimodality therapy including surgery, chemotherapy and radiotherapy. Here we are reviewing old concepts about the disease and modern understandings of the origin, classification, pathogenesis and recent advances in the treatment of the uterine carcinosarcoma.

    2010-09-01

    Full Text Available Generation and consumption of information are among the functions unique to higher education. Scholarly communication plays an essential role in this process to such a degree that some consider it as being the cornerstone of science. Thus it could be said that no education could be realized without communication. Scientometrists analyze and assess formal scientific communications by studying the level of citation of such scientific outputs as books, journals and etc. Nevertheless, there is a special type of communication that lacks any external manifestation such as citations. Informal learning and education are indebted to such communication. This kind of informal communication for generating knowledge leads to an informal association among the scholars, which is called as "The invisible college". There are various definitions and interpretations concerning an invisible college. According to Price’s opinion, an invisible college is comprised of over a hundred colleagues that are engaged in communication with one another. He believed that members in such an association are reasonably in touch with and could consult and influence one another. The present paper, by reacquainting with the concept of invisible college, would review the role of informal links in the production of knowledge and higher education system, various assessment methods and critical notes, as well as the impact of modern ICT tools on the concept of invisible college.

    McGhee, Gerry; Marland, Glenn R; Atkinson, Jacqueline

    2007-11-01

    This paper is a report of a discussion of the arguments surrounding the role of the initial literature review in grounded theory. Researchers new to grounded theory may find themselves confused about the literature review, something we ourselves experienced, pointing to the need for clarity about use of the literature in grounded theory to help guide others about to embark on similar research journeys. The arguments for and against the use of a substantial topic-related initial literature review in a grounded theory study are discussed, giving examples from our own studies. The use of theoretically sampled literature and the necessity for reflexivity are also discussed. Reflexivity is viewed as the explicit quest to limit researcher effects on the data by awareness of self, something seen as integral both to the process of data collection and the constant comparison method essential to grounded theory. A researcher who is close to the field may already be theoretically sensitized and familiar with the literature on the study topic. Use of literature or any other preknowledge should not prevent a grounded theory arising from the inductive-deductive interplay which is at the heart of this method. Reflexivity is needed to prevent prior knowledge distorting the researcher's perceptions of the data.

    2016-08-01

    The objective of this first literature review, in this area, is to unveil the current status of knowledge on superstition in sport. Its outcome reveals that superstitious behaviors vary with the type of sport, athletic level, as well as athletic role. In agreement with past theories, they increase with the level of challenge, as reflected by the importance of the competition, as well as with the level of uncertainty. Cultural factors, in conjunction with the education level, as well as gender, have a strong influence on superstitious behaviors in sports. Based on current thoughts, religiosity and superstition are different psychological constructs used as psychological aids by several athletes. Personality factors appear to mediate the manifestation of the behavior. Elite athletes are clearly more superstitious than non-elite athletes, An interaction between athletic skill and task-difficulty emerges to be another strong predictor of superstition in sport. It is evident that a set of complex personal and situational factors interact in the manifestation of superstitious behavior in sport that is used for the regulation of emotions in a quest for optimal performance. It is concluded that the objective benefits (i.e., success) of superstition in sport may be ascribed to the placebo effect that yields an increased sense of control and mental reassurance in unpredictable contest situations. © 2016 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

    2017-12-01

    The phenomenon of orthorexia nervosa (ON) has been noted by clinicians since 1996 and described in the scientific literature, and yet there is no formal recognition of ON as a psychiatric diagnosis. Review the latest available literature regarding diagnoses similarities, presentation uniqueness, assessment/assessment tools, and suggested treatments of ON. A literature search of four databases focusing on articles published between 2000 and 2016 was conducted to evaluate the status of the literature on Orthorexia. Among the 15 articles selected for this review, similarities with other psychiatric disorders emerged, confusion about use of assessment tools existed, and the lack of evidence based treatments for ON was pronounced. More research is needed to determine the prevalence of pathologically unhealthy, obsessive, "self-defined healthy," eating behaviors, and to determine if ON is a unique eating disorder or just a subset of another disorder.

    2017-01-01

    Purpose: Reflection in medical diagnosis has been said to prevent errors by minimizing flaws in clinical reasoning. This claim, however, has been much disputed. While some studies show reflective reasoning to improve diagnostic performance, others find it to add nothing. This paper presents a narrative review of the literature on reflection in medical diagnosis aimed at addressing two questions: (1) how reflective reasoning has been conceived in this literature; and (2) what is the effect of ...

    2017-01-01

    This paper outlines a systematic literature review undertaken to establish current evidence regarding the impact of Business Intelligence (BI) on health system decision making and organizational performance. The review also examined BI implementation factors contributing to these constructs. Following the systematic review, inductive content analysis was used to categorize themes within the eight articles identified. This study demonstrated there is little evidence based literature focused on BI impact on organizational decision making and performance within health care. There was evidence found that BI does improve decision making. Implementation success was found to be dependent on several factors, many of which relate to broader organizational culture and readiness.

  20. Vicarious learning: a review of the literature.

    Roberts, Debbie

    2010-01-01

    Experiential learning theory stresses the primacy of personal experience and the literature suggests that direct clinical experience is required in order for learning to take place. However, raw or first hand experience may not be the only mechanisms by which students engage in experiential learning. There is a growing body of literature within higher education which suggests that students are able to use another's experience to learn: vicarious learning. This literature review aims to outline vicarious learning within a nursing context. Many of the studies regarding vicarious learning are situated within Higher Education in general, however, within the United States these relate more specifically to nursing students. The literature indicates the increasing global interest in this area. This paper reveals that whilst the literature offers a number of examples illustrating how vicarious learning takes place, opinion on the role of the lecturer is divided and requires further exploration and clarification. The implications for nurse education are discussed.

  2. Integrative Literature Review: Ascertaining Discharge Readiness for Pediatrics After Anesthesia.

    Science.gov (United States)

    Whitley, Deborah R

    2016-02-01

    Unplanned hospital readmissions after the administration of general anesthesia for ambulatory procedures may contribute to loss of reimbursement and assessment of financial penalties. Pediatric patients represent a unique anesthetic risk. The purpose of this integrative literature review was to ascertain specific criteria used to evaluate discharge readiness for pediatric patients after anesthesia. This study is an integrative review of literature. An integrative literature search was conducted and included literature sources dated January 2008 to November 2013. Key words included pediatric, anesthesia, discharge, criteria, standards, assessment, recovery, postoperative, postanesthesia, scale, score, outpatient, and ambulatory. Eleven literature sources that contributed significantly to the research question were identified. Levels of evidence included three systematic reviews, one randomized controlled trial, three cohort studies, two case series, and two expert opinions. This integrative literature review revealed evidence-based discharge criteria endorsing home readiness for postanesthesia pediatric patients should incorporate consideration for physiological baselines, professional judgment with regard to infant consciousness, and professional practice standards/guidelines. Additionally, identifying and ensuring discharge to a competent adult was considered imperative. Nurses should be aware that frequently used anesthesia scoring systems originated in the 1970s, and this review was unable to locate current literature examining the reliability and validity of their use in conjunction with modern anesthesia-related health care practices.

  3. Neonicotinoids in the Canadian aquatic environment: a literature review on current use products with a focus on fate, exposure, and biological effects.

    Anderson, J C; Dubetz, C; Palace, V P

    2015-02-01

    Developed to replace organophosphate and carbamate insecticides, neonicotinoids are structurally similar to nicotine. The three main neonicotinoid insecticides, imidacloprid, clothianidin, and thiamethoxam, are being re-evaluated by Health Canada's Pest Management Regulatory Agency (PMRA). An important aspect of the re-evaluation is the potential for effects in non-target organisms, including aquatic organisms. Leaching into surface waters is one of the major concerns surrounding extensive use of neonicotinoids, especially in close proximity to water bodies. The PMRA has classified IMI as 'persistent' with a 'high' leaching potential. Globally, neonicotinoids have been detected in a variety of water bodies, typically at concentrations in the low μg/L range. While IMI has been included in some monitoring exercises, there are currently very few published data for the presence of CLO and THM in Canadian water bodies. The majority of neonicotinoid toxicity studies have been conducted with IMI due to its longer presence on the market and high prevalence of use. Aquatic insects are particularly vulnerable to neonicotinoids and chronic toxicity has been observed at concentrations of IMI below 1 μg/L. Acute toxicity has been reported at concentrations below 20 μg/L for the most sensitive species, including Hyalella azteca, ostracods, and Chironomus riparius. Fish, algae, amphibians, and molluscs are relatively insensitive to IMI. However, the biological effects of THM and CLO have not been as well explored. The Canadian interim water quality guideline for IMI is 0.23 μg/L, but there is currently insufficient use, fate, and toxicological information available to establish guidelines for CLO and THM. Based on concentrations of neonicotinoids reported in surface waters in Canada and globally, there is potential for aquatic invertebrates to be negatively impacted by neonicotinoids. Therefore, it is necessary to address knowledge gaps to inform decisions around guidelines

  4. Would glucagon-like peptide-1 receptor agonists have efficacy in binge eating disorder and bulimia nervosa? A review of the current literature.

    McElroy, Susan L; Mori, Nicole; Guerdjikova, Anna I; Keck, Paul E

    2018-02-01

    Binge eating, eating an abnormally large amount of food in a discrete period of time with a sense of loss of control over eating, is a defining feature of the eating disorders binge eating disorder (BED) and bulimia nervosa (BN). Both BED and BN are important public health problems for which there are few medical treatments. However, almost all drugs with central nervous system-mediated weight loss properties studied thus far in randomized, placebo-controlled trials in persons with BED or BN have been efficacious for reducing binge eating behavior. Glucagon-like peptide-1 (GLP-1) receptor agonists, marketed for type 2 diabetes and chronic weight management, produce weight loss in a dose dependent manner and have favorable psychiatric adverse event profiles. We hypothesize that GLP-1 receptor agonists will safely reduce binge eating behavior in individuals with BED or BN, including those with co-occurring psychiatric disorders, and propose that randomized, placebo-controlled clinical trials of GLP-1 receptor agonists be conducted in persons with BED and those with BN. To support this hypothesis, we review studies of GLP-1 and GLP-1 receptor agonists in preclinical models of binge eating, studies of GLP-1 levels in individuals with BED or BN, and preliminary data of GLP-1 receptor agonists in humans with abnormal eating behavior.

    Uterine leiomyomas are common gynecologic tumor in reproductive-aged women, by age 50, diagnosis shared by urologist, gynecologists and radiologists. The goal of this article is to review the current literature, study the impact of leiomyoma on female lower urinary tract, examine the cause female sexual dysfunction and provide a comprehensive review of current diagnostic, imaging studies, and current treatment of leiomyoma. Clinical leiomyoma studies published from 1956 through 2015 were identified using the PubMed search engines and the key words leiomyoma, fibroid in the current literature. Impact of leiomyoma on the lower urinary tract including female sexual dysfunction was reviewed with terms of "urinary retention", "bladder", "urethra", "dyspareunia", "incontinence", "incomplete bladder emptying", "female sexual dysfunction", and "lower urinary tract" to study the urological and sexual effects of leiomyoma. Literature related to leiomyoma was reviewed from 1965 to present. Women with uterine leiomyomata complained of pelvic pain, menstrual irregularities, infertility, lower urinary tract symptoms and sexual dysfunction. Leiomyoma is a common tumor of the uterus that often clinically impacts on the lower urinary tract and results in urological and sexual symptoms. Leiomyoma can compress and grow into and become adherent to the bladder and surrounding pelvic organs or metastasize into peritoneal organs. Leiomyoma can enlarge and compress the urinary bladder, urethra, and lower end of the ureters. Leiomyoma can cause embarrassing sexual dysfunction in females. Current literature of non-surgical and surgical therapy of leiomyoma is described.

    2012-01-01

    Concrete containment structures and cement-based fills and waste forms are used at the Savannah River Site to enhance the performance of shallow land disposal systems designed for containment of low-level radioactive waste. Understanding and measuring transport through cracked concrete is important for describing the initial condition of radioactive waste containment structures at the Savannah River Site (SRS) and for predicting performance of these structures over time. This report transmits the results of a literature review on transport through cracked concrete which was performed by Professor Jason Weiss, Purdue University per SRR0000678 (RFP-RQ00001029-WY). This review complements the NRC-sponsored literature review and assessment of factors relevant to performance of grouted systems for radioactive waste disposal. This review was performed by The Center for Nuclear Waste Regulatory Analyses, San Antonio, TX, and The University of Aberdeen, Aberdeen Scotland and was focused on tank closure. The objective of the literature review on transport through cracked concrete was to identify information in the open literature which can be applied to SRS transport models for cementitious containment structures, fills, and waste forms. In addition, the literature review was intended to: (1) Provide a framework for describing and classifying cracks in containment structures and cementitious materials used in radioactive waste disposal, (2) Document the state of knowledge and research related to transport through cracks in concrete for various exposure conditions, (3) Provide information or methodology for answering several specific questions related to cracking and transport in concrete, and (4) Provide information that can be used to design experiments on transport through cracked samples and actual structures.

    Teuta Ismaili Muharremi

    2015-12-01

    Full Text Available This paper elaborates on currency crisis, focusing on the main factors causing the currency crisis. After a brief overview of the main factors driving currency crisis, the paper provides a literature review highlighting that the history of the global economy experienced a number of currency crisis whereas as relates to the triggers of the currency crisis there are three generations of models that have been used to explain currency crisis during the last four decades. Underscoring the role of the government in financial market, in particular the evolution of this role as a result of the recent global financial crisis and highlighting other factors that trigger such crisis, the paper concludes that the potential financial crisis can be addressed using early warning system, which consists of indicators proven to be beneficial in anticipation of the currency crisis, and using the advanced empirical models of currency crisis. In this context the paper reveals that currency crisis are associated with all factors impacting them such as inflation, real exchange rate, import growth, US interest rates, public debt/GDP, and current account/GDP – all with a slightly different time lag.

    2018-01-01

    Acute transverse myelitis (ATM) is a rare inflammatory demyelinating disorder characterized by relatively acute onset of motor, sensory, and autonomic dysfunction. Children comprise 20% of total cases of ATM. In this review, we described the current literature on childhood ATM, focusing on the epidemiology, pathogenesis, clinical presentation, approach to diagnosis, differential diagnosis, treatment and outcome in the pediatric population. We searched the related articles in electronic databases such as Scopus, EMBASE, Google Scholar, and PubMed. All study designs were included and the essential key words for searching were myelitis, acute transverse myelitis, childhood transverse myelitis, and acquired demyelinating syndromes. The related data focusing on the epidemiology, pathogenesis, clinical presentation, diagnostic approach and differential diagnosis, treatment and outcome of pediatric ATM were gathered and described. ATM is a heterogeneous disorder in children with a broad spectrum of clinical presentation, etiology, and outcome. It may be the first presentation of relapsing acquired demyelinating syndromes and also must be distinguished from compressive and noninflamatory myelopathies. Correct diagnosis is crucial for treatment and prognosis.

    2016-01-01

    One of the goals of simulation is to teach subjects critical skills and knowledge applicable to live encounters, without the risk of harming actual patients. Although simulation education has surged in medical training over the last two decades, several ethically challenging educational methods have arisen. Simulated death has arisen as one of these challenging issues and currently there is no consensus regarding how to best manage this controversial topic in the simulated environment. The goal of this review is to analyze how simulated mortality has been used and discover whether or not this tool is beneficial to learners. In May 2016, the authors performed a literature search on both Pubmed and the Cochrane database using multiple variations of keywords; they then searched bibliographies and related articles. There were 901 articles acquired in the initial search. The authors eliminated articles that were not relevant to the subject matter. After adding articles from bibliographies and related articles, the authors included the 43 articles cited in this article. As a result, the authors of this article believe that death, when used appropriately in simulation, can be an effective teaching tool and can be used in a responsible manner.

    2017-05-01

    Full Text Available Aim: The aims of the literature review were to identify and analyze factors affecting job satisfaction of midwives. Design: A literature review. Methods: Included in the literature review were full texts of papers published in English language from 1990 to 2014. The search for relevant data was performed using the electronic databases CINAHL, Medline, Science Direct and Wiley Online Library. From a total of 43 studies found, 11were analyzed as quantitative studies that fulfilled the specified criteria. Results: Job satisfaction of midwives is affected by a lack of support from the management of healthcare facilities, low salary, understaffing, insufficient time for professional activities, work-family imbalance, high workload, physical demands, inadequate professional development, working environment, stress and low autonomy at work. Midwives showed signs of exhaustion, fatigue, hostility and depression, contributing to job turnover. Conclusion: The literature review presents the factors influencing job satisfaction of midwives. This is affected by many variable determinants, which create a feeling of job satisfaction of midwives, but can also lead to job dissatisfaction and, consequently, high turnover. Keywords: midwives, job satisfaction.

    2017-01-06

    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. 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. 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. As a result, we reviewed more than 5000 scientific studies published in the last 10 years, selected the most significant approaches, and thoroughly surveyed the health

  19. Suicide in deaf populations: a literature review.

    Turner, Oliver; Windfuhr, Kirsten; Kapur, Navneet

    2007-10-08

    Studies have found that deaf individuals have higher rates of psychiatric disorder than those who are hearing, while at the same time encountering difficulties in accessing mental health services. These factors might increase the risk of suicide. However, the burden of suicidal behaviour in deaf people is currently unknown. The aim of the present review was to provide a summary of literature on suicidal behaviour with specific reference to deaf individuals. The objectives of the review were to establish the incidence and prevalence of suicidal behaviour in deaf populations; describe risk factors for suicidal behaviour in deaf populations; describe approaches to intervention and suicide prevention that have been used in deaf populations. A number of electronic databases (e.g. Medline, PsycINFO, CINAHL, EMBASE, Dissertation Abstracts International, Web of Science, ComDisDome, ASSIA, Education Sage Full Text, Google Scholar, and the grey literature databases FADE and SIGLE) were explored using a combination of key words and medical subject headings as search terms. Reference lists of papers were also searched. The Science and Social Sciences Citation Index electronic databases were used to identify studies that had cited key papers. We also contacted experts and organisations with an interest in the field. Very few studies focussed specifically on suicide in deaf populations. Those studies that were included (n = 13) generally involved small and unrepresentative samples. There were limited data on the rate of suicidal behaviour in deaf people. One study reported evidence of hearing impairment in 0.2% of all suicide deaths. Another found that individuals with tinnitus seen in specialist clinics had an elevated rate of suicide compared to the general population. The rates of attempted suicide in deaf school and college students during the previous year ranged from 1.7% to 18%, with lifetime rates as high as 30%. Little evidence was found to suggest that risk factors for

    Miller, C.T.; Mayer, A.S.

    1990-01-01

    This review was prepared under the auspices of the WPCF Research Committee of the annual Literature Review issue of the Journal; because of logistical reasons it could not be published in June. However, in view of the growing importance of the subject, the review is presented here as a supplement to the June Literature Review issue that has not been through the Journal peer review process. In this review, distinctions are made between single-, two-, and three-phase systems. Single-phase systems refer to groundwater systems subjected to saturated flow conditions, whereas the two- and three-phase systems include groundwater systems subjected to unsaturated flow conditions, or conditions influenced by immiscible organic fluids such as petroleum products. Within the single-, two-, and three-phase system categories, subdivisions are made between physical, chemical, or biological processes such as hydrodynamics, sorption/desorption, chemical reactions, and biodegradation. Specialized areas such as radon and radionuclide transport, facilitated transport, and saline groundwaters also are treated separately. Rounding out this year's review, papers concerning groundwater quality monitoring, remediation, and management are discussed

    2018-05-04

    Recently, public health has acknowledged racism as a social determinant of health. Much evidence exists on the impact of individual-level racism and discrimination, with little to no examination of racism from the standpoint of systems and structures. The purpose of this systematic literature review is to analyze the extent to which public health currently addresses systemic racism in the published literature. Utilizing the PRISMA guidelines, this review examines three widely used databases to examine published literature covering the topic as well as implications for future research and practice. A total of 85 articles were included in the review analysis after meeting study criteria. Across numerous articles, the terms racism and systemic racism are largely absent. A critical need exists for an examination of the historical impact of systemic racism on the social determinants of health and health of marginalized populations.

    Full Text Available The rapid evolution of technology, has offered access to a variety of applications and technologies to healthcare professionals. New operating systems developed in the field of mobile devices revolutionized the way in which they are used. One of the main features offered by advanced software of a smartphone is the user’s access to a wealth of new, impressive applications across several operating systems for smartphones. The health related applications provided through smartphones, promote more active involvement of patients and healthcare professionals to provided care and are a new tool for improving health. The purpose of this abstract paper or article was to refer to applications currently used in the health sector, indicating specific capabilities they offer through review of electronic literature, focusing on scientific articles published in databases (PubMed, Scopus, etc. referring to the potentials they offer. It seems that several health related applications have been developed, that can be classified into two main categories. One category comprises applications that are informative, i.e. provide information to the user about health issues, allowing a person to read, gather resources to make decisions, but also to introduce its own data. These applications are mostly used by health care professionals. The second major category of applications refers to those related to help with the diagnosis, treatment and decision-making on various health related issues and in some cases take the form of consultancy, substituting the health care professional. As technology advances, the development of new health related applications is expected, specialized, with new features. Finally, the use of such applications by health care professionals is essential.

  13. LITERATURE REVIEW OF BORIC ACID SOLUBILITY DATA

    Energy Technology Data Exchange (ETDEWEB)

    2011-09-22

    A new solvent system is being evaluated for use in the Modular Caustic-Side Solvent Extraction Unit (MCU) and in the Salt Waste Processing Facility (SWPF). The new system replaces the current dilute nitric acid strip solution with 0.01 M boric acid. This literature study is performed to determine if there is a potential for boric acid to crystallize in the lines with emphasis on the transfer lines to the Defense Waste Processing Facility. This report focuses on the aqueous phase chemistry of boric acid under conditions relevant to MCU and SWPF. Operating and transfer conditions examined for the purpose of this review include temperatures between 13 C (McLeskey, 2008) and 45 C (Fondeur, 2007) and concentrations from 0 to 3M in nitric acid as well as exposure of small amounts of entrained boric acid in the organic phase to the sodium hydroxide caustic wash stream. Experiments were also conducted to observe any chemical reactions and off-gas generation that could occur when 0.01 M boric acid solution mixes with 3 M nitric acid solution and vice versa. Based on the low concentration (0.01M) of boric acid in the MCU/SWPF strip acid and the moderate operating temperatures (13 C to 45 C), it is unlikely that crystallization of boric acid will occur in the acid strip solution under process or transfer conditions. Mixing experiments of boric and nitric acid show no measurable gas generation (< 1 cc of gas per liter of solution) under similar process conditions.

    Full Text Available Pachydermodactyly is a rare, benign form of digital fibromatosis, characterized by asymptomatic and progressive, periarticular and usually symmetrical soft tissue finger swelling, specifically on the lateral aspects of the proximal interphalangeal joints mainly of the second, third, and fourth fingers; it mostly affects young adolescents and is probably due to repeated mechanical injury of the skin (such as repeated clasping or rubbing of crossed fingers, sometimes as a result of obsessive-compulsive disorder, which must be distinguished from obsessive “chewing pads”. This paper presents a male patient aged 19, who presented with first symptoms at the age of 12, and was diagnosed with periarticular hypertrophy: localized soft tissue thickening around the proximal interphalangeal joints of all fingers except the thumbs; slight hypertrophy of the skin; absence of subjective complaints; normal joint function. Dermatological status on admission revealed: symmetrical soft tissue swelling of all fingers of both hands except the thumbs at the level of the proximal interphalangeal joints; normal appearance of the distal parts of all fingers; thickening at the level of the proximal interphalangeal joints, bilateral, almost symmetrical hypertrophy (ulnar and radial of phalanges of the affected fingers except both index fingers, affecting only the ulnar side. The skin lesions were pain-free on palpation, with homogeneous texture and elastic consistency, freely movable over underlying structures. The affected joints showed no functional deficit. The test results, sonography, radiography and histopathology confirmed our clinical diagnosis-pachydermodactyly. The review of the currently available literature, published between 1973 and 2014, including 99 papers and 160 patients, provided important insight into the characteristics and variations of the disease.

  15. Toothbrush Contamination: A Review of the Literature

    Directory of Open Access Journals (Sweden)

    Michelle R. Frazelle

    2012-01-01

    Full Text Available Toothbrushes are commonly used in hospital settings and may harbor potentially harmful microorganisms. A peer-reviewed literature review was conducted to evaluate the cumulative state of knowledge related to toothbrush contamination and its possible role in disease transmission. A systematic review was conducted on adult human subjects through three distinct searches. The review resulted in seven experimental and three descriptive studies which identified multiple concepts related to toothbrush contamination to include contamination, methods for decontamination, storage, design, and environmental factors. The selected studies found that toothbrushes of healthy and oral diseased adults become contaminated with pathogenic bacteria from the dental plaque, design, environment, or a combination of factors. There are no studies that specifically examine toothbrush contamination and the role of environmental factors, toothbrush contamination, and vulnerable populations in the hospital setting (e.g., critically ill adults and toothbrush use in nursing clinical practice.

    2011-01-01

    This article aims to examine gender stereotypes in relation to men in nursing, discuss gender discrimination cases in nursing, and explore methods used for promoting equal educational opportunities during nursing studies. The literature review was based on related databases, such as CINAHL, Science Direct, MEDLINE, and EBSCO. Legal case studies are included in order to provide a more practical example of those barriers existing for men pursuing nursing, as well as statistical data concerning gender discrimination and male attrition to nursing schools in relation to those barriers. These strengthen the validity of the manuscript. Literature review showed that gender discrimination is still prevalent within nursing profession. Nursing faculty should prepare male nursing students to interact effectively with female clients as well. Role modeling the therapeutic relationship with clients is one strategy that may help male students. In general, the faculty should provide equal learning opportunities to nursing students.

  18. Peripartum Cardiomyopathy: A Current Review

    Directory of Open Access Journals (Sweden)

    Katie M. Twomley

    2010-01-01

    Full Text Available Peripartum cardiomyopathy (PPCM is a rare but potentially lethal complication of pregnancy occurring in approximately 1 : 3,000 live births in the United States although some series report a much higher incidence. African-American women are particularly at risk. Diagnosis requires symptoms of heart failure in the last month of pregnancy or within five months of delivery in the absence of recognized cardiac disease prior to pregnancy as well as objective evidence of left ventricular systolic dysfunction. This paper provides an updated, comprehensive review of PPCM, including emerging insights into the etiology of this disorder as well as current treatment options.

    Wu, Yelena P; Aylward, Brandon S; Roberts, Michael C; Evans, Spencer C

    2012-08-01

    Literature reviews are an essential step in the research process and are included in all empirical and review articles. Electronic databases are commonly used to gather this literature. However, several factors can affect the extent to which relevant articles are retrieved, influencing future research and conclusions drawn. The current project examined articles obtained by comparable search strategies in two electronic archives using an exemplar search to illustrate factors that authors should consider when designing their own search strategies. Specifically, literature searches were conducted in PsycINFO and PubMed targeting review articles on two exemplar disorders (bipolar disorder and attention deficit/hyperactivity disorder) and issues of classification and/or differential diagnosis. Articles were coded for relevance and characteristics of article content. The two search engines yielded significantly different proportions of relevant articles overall and by disorder. Keywords differed across search engines for the relevant articles identified. Based on these results, it is recommended that when gathering literature for review papers, multiple search engines should be used, and search syntax and strategies be tailored to the unique capabilities of particular engines. For meta-analyses and systematic reviews, authors may consider reporting the extent to which different archives or sources yielded relevant articles for their particular review.

    Several types of vasculitis have been observed and reported in temporal association with the administration of various vaccines. A systematic review of current evidence is lacking. This systematic literature review aimed to assess available evidence and current reporting practice of vasculitides as adverse events following immunization (AEFI). We reviewed the literature from 1st January 1994 to 30th June 2014. This review comprises randomized controlled trials, observational studies, case series, case reports, reviews and comments regardless of vaccine and target population. The initial search resulted in the identification of 6656 articles. Of these, 157 articles were assessed for eligibility and 75 studies were considered for analysis, including 6 retrospective/observational studies, 2 randomized controlled trials, 7 reviews, 11 case series, 46 case reports and 3 comments. Most of the larger, higher quality studies found no causal association between vaccination and subsequent development of vasculitis, including several studies on Kawasaki disease and Henoch-Schönlein purpura (IgA vasculitis). Smaller case series reported a few cases of vasculitis following BCG and vaccines against influenza and hepatitis. Only 24% of the articles reported using a case definition of vasculitis. Existing literature does not allow establishing a causative link between vaccination and vasculitides. Further investigations were strengthened by the use of standardized case definitions and methods for data collection, analysis and presentation to improve data comparability and interpretation of vasculitis cases following immunization.

  6. BOOK REVIEW: The Current Comparator

    Science.gov (United States)

    Petersons, Oskars

    1989-01-01

    This 120-page book is a concise, yet comprehensive, clearly-written and well-illustrated monograph that covers the subject matter from basic principles through design, construction and calibration details to the principal applications. The book will be useful, as a primer, to the uninitiated and, as a reference book to the practitioner involved with transformer-type ratio devices. The length of the book and the style of presentation will not overburden any informed reader. The described techniques and the cited references are primarily from the work at the National Research Council, Canada (NRC). Any omissions, however, are not serious with respect to coverage of the subject matter, since most of the development work has been done at NRC. The role of transformers and transformer-like devices for establishing accurate voltage and current ratios has been recognized for over half a century. Transformer techniques were much explored and developed in the fifties and sixties for accuracy levels suitable for standards laboratories. Three-winding voltage transformers were developed for scaling of impedances in connection with the calculable Thompson Lampard capacitor; three-winding current transformers or current comparators were initially explored for the calibration of current transformers and later for specialized impedance measurements. Extensive development of the current comparator and its applications has been and is still being conducted at the NRC by a team that was started and, until his retirement, led by N L Kusters. The team is now led by W J M Moore. He and P N Miljanic, the authors of this book, have had the principal roles in the development of the current comparator. It is fortunate for the field of metrology that considerabe resources and a talented group of researchers were available to do this development along with mechanisms that were available to transfer this technology to a private sector instrument manufacturer and, thus, disseminate it world wide

  7. Suicide in deaf populations: a literature review

    Full Text Available Abstract Background Studies have found that deaf individuals have higher rates of psychiatric disorder than those who are hearing, while at the same time encountering difficulties in accessing mental health services. These factors might increase the risk of suicide. However, the burden of suicidal behaviour in deaf people is currently unknown. The aim of the present review was to provide a summary of literature on suicidal behaviour with specific reference to deaf individuals. The objectives of the review were to establish the incidence and prevalence of suicidal behaviour in deaf populations; describe risk factors for suicidal behaviour in deaf populations; describe approaches to intervention and suicide prevention that have been used in deaf populations. Methods A number of electronic databases (e.g. Medline, PsycINFO, CINAHL, EMBASE, Dissertation Abstracts International, Web of Science, ComDisDome, ASSIA, Education Sage Full Text, Google Scholar, and the grey literature databases FADE and SIGLE were explored using a combination of key words and medical subject headings as search terms. Reference lists of papers were also searched. The Science and Social Sciences Citation Index electronic databases were used to identify studies that had cited key papers. We also contacted experts and organisations with an interest in the field. Results Very few studies focussed specifically on suicide in deaf populations. Those studies that were included (n = 13 generally involved small and unrepresentative samples. There were limited data on the rate of suicidal behaviour in deaf people. One study reported evidence of hearing impairment in 0.2% of all suicide deaths. Another found that individuals with tinnitus seen in specialist clinics had an elevated rate of suicide compared to the general population. The rates of attempted suicide in deaf school and college students during the previous year ranged from 1.7% to 18%, with lifetime rates as high as 30

  8. Impact of childhood chronic illnesses on siblings: a literature review.

    Science.gov (United States)

    O' Brien, Irene; Duffy, Anita; Nicholl, Honor

    Childhood illness can have a significant impact on families, particularly on the ill child's siblings. There is a dearth of published literature focusing on the needs of siblings of ill children. This literature review aims to provide an overview of the current healthcare literature in relation to the impact of childhood chronic illness or disability on siblings. A literature review was undertaken by searching the databases CINAHL, PsycINFO, ProQuest and Cochrane Library for relevant articles in English using the search terms: 'siblings', 'chronic illness', 'disability', 'cancer', 'sibling relations', 'sibling adjustment', 'coping', 'family-centred care', 'sibling interventions', 'camps', 'autism', 'Down's syndrome'. Seventeen research studies in total were reviewed. This review focuses on three sibling groups related to children suffering from autism, cancer and Down's syndrome, and are discussed under the following headings: sibling adjustment; family functioning and sibling's coping resources; and intervention programmes. The literature revealed that siblings of children with Down's syndrome were well adjusted to living with their brother or sister. However, there was conflicting information on the adjustment of siblings of children with cancer and autism. An awareness of the harmful effect that living with childhood illness and disability can have on some siblings is essential to enable healthcare professionals to provide supportive interventions to protect siblings' physical and emotional wellbeing.

  10. Defining resilience: A preliminary integrative literature review

    Science.gov (United States)

    Wilt, Bonnie; Long, Suzanna K.; Shoberg, Thomas G.

    2016-01-01

    The term “resilience” is ubiquitous in technical literature; it appears in numerous forms, such as resilience, resiliency, or resilient, and each use may have a different definition depending on the interpretation of the writer. This creates difficulties in understanding what is meant by ‘resilience’ in any given use case, especially in discussions of interdisciplinary research. To better understand this problem, this research constructs a preliminary integrative literature review to map different definitions, applications and calculation methods of resilience invoked within critical infrastructure applications. The preliminary review uses a State-of-the-Art Matrix (SAM) analysis to characterize differences in definition across disciplines and between regions. Qualifying the various usages of resilience will produce a greater precision in the literature and a deeper insight into types of data required for its evaluation, particularly with respect to critical infrastructure calculations and how such data may be analyzed. Results from this SAM analysis will create a framework of key concepts as part of the most common applications for “resilient critical infrastructure” modeling.

    Full Text Available The use of learning technologies, especially multimedia provide varied facilities for students’ learning that are not possible with other media. Pedagogical literature has proved that individuals have different learning styles. Flipped classroom is a pedagogical approach which means that activities that have traditionally taken place inside the classroom take place outside the classroom and vice versa. Flipped classroom environment ensures that students become more active participants compared with the traditional classroom. The purpose of this paper is to fulfil the needs regarding the review of recent literature on the use of flipped classroom approach in education. The contribution of flipped classroom to education is discussed in relation to the change of students' and instructors' role. Subsequently, flipped classroom applications in various disciplines of education are illustrated. The recommendations made in the literature for design specifications that integrate flipped classrooms with technology are discussed. The paper concludes that a careful consideration of the warnings and recommendations made in the literature can help to produce effective flipped classroom environments and also this paper attempts to inform those who are thinking of using new technologies and approaches to deliver courses.

    Bernstein, Joseph A.; Didier, Peter J.

    2015-01-01

    In general, veterinary dermatologists do not have extensive clinical experience of nonhuman primate (NHP) dermatoses. The bulk of the published literature does not provide an organized evidence-based approach to the NHP dermatologic case. The veterinary dermatologist is left to extract information from both human and veterinary dermatology, an approach that can be problematic as it forces the clinician to make diagnostic and therapeutic decisions based on two very disparate bodies of literature. A more cohesive approach to NHP dermatology – without relying on assumptions that NHP pathology most commonly behaves similarly to other veterinary and human disease – is required. This review of the dermatology of NHP species includes discussions of primary dermatoses, as well as diseases where dermatologic signs represent a significant secondary component, provides a first step towards encouraging the veterinary community to study and report the dermatologic diseases of nonhuman primates.

    In previous decades, manufacturers faced a lot of challenges because of globalization and high competition in markets. These problems arise from shortening product life cycle, rapid variation in demand of products, and also rapid changes in manufcaturing technologies. Nowadays most manufacturing companies expend considerable attention for improving flexibility and responsiveness in order to overcome these kinds of problems and also meet customer's needs. By considering the trend toward the shorter product life cycle, the manufacturing environment is towards manufacturing a wide variety of parts in small batches [1]. One of the major techniques which are applied for improving manufacturing competitiveness is Cellular Manufacturing System (CMS). CMS is type of manufacturing system which tries to combine flexibility of job shop and also productivity of flow shop. In addition, Dynamic cellular manufacturing system which considers different time periods for the manufacturing system becomes an important topic and attracts a lot of attention to itself. Therefore, this paper made attempt to have a brief review on this issue and focused on all published paper on this subject. Although, this topic gains a lot of attention to itself during these years, none of previous researchers focused on reviewing the literature of that which can be helpful and useful for other researchers who intend to do the research on this topic. Therefore, this paper is the first study which has focused and reviewed the literature of dynamic cellular manufacturing system.

  16. Gossypibomas in India - A systematic literature review

    T Patial

    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.

  17. Social marketing and breastfeeding: a literature review.

    Schmidt, Manuela

    2013-02-08

    Through the review of relevant literature this study illuminates the concepts of social marketing and breastfeeding. It specifically discusses the positioning of the link between social marketing and breastfeeding within different fields of study and develops a theoretical framework that tries to bridge the gap between those disciplines. Various electronic databases were used and through systematic selection 11 scientific articles were identified that this literature review is based on. The review indicates that the relationship between social marketing and breastfeeding is complex. There are indications that this relationship is being investigated within three distinct fields of research: psychology/education, public health and marketing. Depending on the research field the emphasis is put on either breastfeeding or social marketing as well as on the other concepts that were discovered to be of importance within this relationship. Namely, group and individual demography as well as behaviour were revealed to be important elements of the link between social marketing and breastfeeding. Based on the results this study concludes that a more multidimensional view on the relationship between the concepts under study is needed since the focus of previous studies is very one-sided and limited to just one element when all elements should be integrated equally.

Method: Literature review in PubMed, Scopus and Cochrane clinical trials, meta-analysis, reviews and case series and control over airway obstruction after extubation that requires reintubation in adults. Results: 6 studies and one clinical practice guidelines were selected. The most common cause of extubation failure is blocking the airway for various reasons (pharyngeal muscle weakness residual effect -often farmacologycal-, laryngospasm, vocal cord paralysis, edema of upper respiratory tract, cervical postoperative hematoma, foreign bodies or secretions. Most cases of re-intubation occurred within 2 hours after extubation. Conclusions: The most common cause of failure after general anesthesia extubation is blocking the airway generally caused by residual neuromuscular blocking effect. Airway obstruction risk increases in airway and head and neck surgery. Difficult intubation guidlines have improved performance and reduced adverse events and similar strategies must be implemented in extubation. The procedure extubation and reintubation should be documented. Working groups airway must be multidisciplinary and include specialists in otolaryngology.

    2010-01-01

    To investigate available shielding methods in an effort to further awareness and understanding of existing preventive measures related to patient exposure in computed tomography (CT) scanning. Searches were conducted to locate literature discussing the effectiveness of commercially available shields. Literature containing information regarding breast, gonad, eye and thyroid shielding was identified. Because of rapidly advancing technology, the selection of articles was limited to those published within the past 5 years. The selected studies were examined using the following topics as guidelines: the effectiveness of the shield (percentage of dose reduction), the shield's effect on image quality, arguments for or against its use (including practicality) and overall recommendation for its use in clinical practice. Only a limited number of studies have been performed on the use of shields for the eyes, thyroid and gonads, but the evidence shows an overall benefit to their use. Breast shielding has been the most studied shielding method, with consistent agreement throughout the literature on its effectiveness at reducing radiation dose. The effect of shielding on image quality was not remarkable in a majority of studies. Although it is noted that more studies need to be conducted regarding the impact on image quality, the currently published literature stresses the importance of shielding in reducing dose. Commercially available shields for the breast, thyroid, eyes and gonads should be implemented in clinical practice. Further research is needed to ascertain the prevalence of shielding in the clinical setting.

    2001-01-01

    Emphysematous gastritis is a rare form of gastritis that results from infection of the stomach wall by gas-forming organisms. Diagnosis of this commonly fatal condition rests on radiological demonstration of gas within the stomach wall. This can be observed on plain radiographs or CT scans of the abdomen. Only by prompt diagnosis and treatment can mortality be avoided. A new case of empysematous gastritis, diagnosed on CT scan by the demonstration of both intramural and portal venous gas, is presented and the literature is reviewed.

    Obturators and facial prostheses are important not only in rehabilitation and aesthetics, but also in patient re-socialisation. The level of reintegration is directly related to the degree of satisfaction with rehabilitation. So, the maxillofacial prosthetics must provide patient satisfaction during treatment. This study aimed to search information in database and conduct a literature review on patient satisfaction with maxillofacial prosthesis. The problems experienced by these patients may decrease when specialists keep the patient on regular inspection. Rehabilitation through alloplasty or prosthetic restoration provides satisfactory conditions in aesthetics and well-being and reinstates individuals in familial and social environment.

    Brandão, Daniela Filipa Soares; Martín, José Ignacio

    2012-06-01

    The Montessori method was initially applied to children, but now it has also been applied to people with dementia. The purpose of this study is to systematically review the research on the effectiveness of this method using Medical Literature Analysis and Retrieval System Online (Medline) with the keywords dementia and Montessori method. We selected lo studies, in which there were significant improvements in participation and constructive engagement, and reduction of negative affects and passive engagement. Nevertheless, systematic reviews about this non-pharmacological intervention in dementia rate this method as weak in terms of effectiveness. This apparent discrepancy can be explained because the Montessori method may have, in fact, a small influence on dimensions such as behavioral problems, or because there is no research about this method with high levels of control, such as the presence of several control groups or a double-blind study.

    1983-01-01

    This review examines the literature on psychological reactions, often referred to as 'compensation neurosis', which occur after an accident and which are thought to be produced or maintained by a compensation claim. Theories and research are examined. The area is complicated and research so far is limited in scope and design. Few accident cases involve compensation claims and the incidence of psychological difficulties across the whole range of cases is unknown. Researchers have considered a number of background factors--severity of injury, pre-existing neurotic traits, social class, sex and age--but there has been little investigation of attitudinal, family, social and employment factors or of progress of the condition and follow-up after settlement. The review identifies a major research need for more adequate screening and sampling of cases and for more systematic investigation of personal and family factors.

    2011-02-01

    The aim of this review is to describe nurses' work motivation from the perspective of staff nurses. This information would be useful for the development of motivation strategies and further research into nurses' work motivation. A thorough review of the research literature. The literature search was performed using four databases: CINAHL, PubMed, PsychINFO, and SocINDEX. Only studies that met the following criteria were selected for review: (1) were published between 1990 and 2009, (2) were written in English, (3) dealt with work motivation, (4) concerned working staff nurses, (5) involved empirical research, (6) clearly and explicitly provided the research results about the factors affecting nurses' work motivation. Altogether 24 studies met these criteria and were included in this review. Inductive content analysis was carried out to analyse and categorise the data. Nursing research has neither clear understanding nor consensus about the concept of work motivation; nor has a universal definition been adopted. Despite limited empirical evidence it may be concluded that staff nurses appear to be motivated. Five categories of factors affecting their work motivation were identified: (1) work-place characteristics, (2) working conditions, (3) personal characteristics, (4) individual priorities, and (5) internal psychological states. Further research is needed to gain a more comprehensive insight into nurses' work motivation and the factors affecting it. This can be achieved by defining the concept of work motivation as precisely as possible, working out a pertinent research methodology, and subsequently developing and testing a theoretical model of nurses' work motivation.

    Karaklic, D; Bungener, C

    2010-10-01

    Borderline personality disorder (BPD) is a serious mental disorder associated with severe emotional, behavioral, cognitive and interpersonal dysfunction, extensive functional impairment and frequent self-destructive behaviour, including deliberate self-harm and suicidal behaviour. For quite some time, BPD has been viewed as a chronic disorder and borderline patients as extremely difficult to treat, doomed to a life of misery. However, those views are changing and there is an increasing recognition that BPD has a far more benign course than previously thought. The purpose of this study is to show how those views changed over time by reviewing longitudinal studies of the course of BPD. We have reviewed the literature published from 1968 to March 2009, using the following key words: borderline personality disorder, outcome, follow-up studies with some additional references. The aim of the longitudinal studies conducted prior to the DSM definition of BPD criteria was to determine whether borderline patients could become psychotic over time, but no such evidence was found even though their functioning was at a relatively low level. The studies conducted after the introduction of BPD in the DSM in 1980 tested the stability and the specificity of BPD diagnosis, concluding that the criteria were relatively stable in the short run since the majority of patients continued to meet them at the follow-up assessments. However, those studies had many methodological drawbacks which limited their generalizability such as small sample sizes, high attrition rates, the absence of comparison groups, etc. Four retrospective studies of the 15-year outcome of borderline patients obtained virtually identical results despite methodological differences, showing that the global functioning of borderline patients improved substantially over time with mean scores of the GAF scale falling within a mild range of impairment. One 27-year retrospective study showed that borderline patients continued

    2013-12-01

    Prostatitis is easily diagnosed but sometimes associated with PSA measurement. An increased PSA in an asymptomatic patient may be associated with antibiotic use to eliminate the inflammatory part and to confirm prostate biopsy. It seems interesting to confirm or infirm these attitudes with a systematic review of the literature We performed a literature review using the words [prostatitis], [acute prostatitis], [prostate specific antigen], [PSA], in the MEDLINE, Pubmed and AMBASE database searching for articles in French or English published in the past 20 years. PSA is not always increased during an acute prostatitis episode. An increased PSA in an asymptomatic man does not seem to be systematically correlated to prostate inflammation. Analyzing the studies, it seems inaccurate to measure PSA value during a febrile urinary infection episode in men. Systematic use of antibiotic to decrease PSA and not performing prostate biopsy is not relevant and may induce resistance to antibiotic and doesn't induce a reduction risk of having prostate biopsy. PSA is unnecessary in case of febrile urinary tract infection in men. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    Concerns related to the complex issue of nursing turnover continue to challenge healthcare leaders in every sector of health care. Voluntary nurse turnover is shown to be influenced by a myriad of inter-related factors, and there is increasing evidence of its negative effects on nurses, patients and health care organizations. The objectives were to conduct a comprehensive review of the related literature to examine recent findings related to the issue of nursing turnover and its causes and consequences, and to identify on methodological challenges and the implications of new evidence for future studies. A comprehensive search of the recent literature related to nursing turnover was undertaken to summarize findings published in the past six years. Electronic databases: MEDLINE, CINAHL and PubMed, reference lists of journal publications. Keyword searches were conducted for publications published 2006 or later that examined turnover or turnover intention in employee populations of registered or practical/enrolled or assistant nurses working in the hospital, long-term or community care areas. Literature findings are presented using an integrative approach and a table format to report individual studies. From about 330 citations or abstracts that were initially scanned for content relevance, 68 studies were included in this summary review. The predominance of studies continues to focus on determinants of nurse turnover in acute care settings. Recent studies offer insight into generational factors that should be considered in strategies to promote stable staffing in healthcare organizations. Nursing turnover continues to present serious challenges at all levels of health care. Longitudinal research is needed to produce new evidence of the relationships between nurse turnover and related costs, and the impact on patients and the health care team.

    2015-12-01

    A profound nursing shortage exists in India where nurses are increasingly outmigrating to practice nursing in surrounding countries and abroad. This is important globally because countries with the lowest nursing and healthcare workforce capacities have the poorest health outcomes. This review sought to synthesize and unify the evidence about nurse migration from India and includes a look at nurse retention within India. A comprehensive literature review was performed to synthesize and unify both qualitative and quantitative research. Bibliographic databases searched included CINAHL, MEDLINE, PsycINFO, and EconLit using associated keywords for empirical and descriptive literature published between January 2004 and May 2014. Hand searches of the Nursing Journal of India from 2004 to February 2014 and the Journal of Nursing Research Society of India from its inception in 2007-February 2014 were also completed. 29 studies were selected and analyzed for the review. Data were appraised for quality; reduced through sub-categorization; extracted; and coded into a framework. Thematic interpretation occurred through comparing and contrasting performed by multiple reviewers. Findings included an exponential growth in nurse recruitment efforts, nurse migration, and a concomitant growth in educational institutions within India with regional variations in nurse migration patterns. Decision-making factors for migration were based on working conditions, salience of family, and the desire for knowledge, skill, technology, adventure and personal enrichment. Challenges associated with migration included questionable recruiting practices, differing scopes of practice encountered after migration and experiences of racism and cultural differences. A shift toward a positive transformation of nursing status in India has resulted in an increased respect for individual nurses and the profession of nursing. This was attributed to the increased globalization of nursing. Results from this

    In support of the goals of Department of Homeland Security’s (DHS) National Protection and Programs Directorate and the Federal Emergency Management Agency, the DHS Office of Science and Technology is seeking to develop and/or modify consequence assessment tools to enable drinking water systems owner/operators to estimate the societal and economic consequences of drinking water disruption due to the threats and hazards. This work will expand the breadth of consequence estimation methods and tools using the best-available data describing water distribution infrastructure, owner/assetlevel economic losses, regional-scale economic activity, and health. In addition, this project will deploy the consequence methodology and capability within a Web-based platform. This report is intended to support DHS effort providing a review literature review of existing assessment tools of water and wastewater systems consequences to disruptions. The review includes tools that assess water systems resilience, vulnerability, and risk. This will help to understand gaps and limitations of these tools in order to plan for the development of the next-generation consequences tool for water and waste water systems disruption.

    Science.gov (United States)

    Love, Katie L

    2016-01-01

    This study presents a systematic literature review exploring the uses and potential benefits of Black Feminism in nursing research. Black Feminism may benefit knowledge development for nursing in a variety of ways, such as illuminating the multifaceted factors of Black women's identities in helping scholars move away from generalization of experiences, to improve understanding of health disparities, and making such changes by broadening the social consciousness of the nurse researchers, who are predominantly White. Discrimination in health disparities may be deconstructed if the focus is placed on asking different research questions and offering different interventions with the social structures that contributes to such actions. When Black Feminism guides the research method (including research questions and analysis), the accuracy of representing the experiences of Black women is increased. In this research, Black Feminism highlights experience, coping mechanisms, spiritual values, a tradition of strength, and a holistic view of identity.

    1976-01-01

    The dense plasma focus (DPF) is a convenient source of short, intense neutron pulses, and dense, high temperature plasma. This review of the literature on the DPF indicates that its operation is still not understood, and attempts to show where the present data is either inadequate or inconsistent. Because the plasma conditions and neutron and x-ray fluxes vary from shot to shot, it is maintained that, to resolve inconsistencies in the present data, spectra need to be measured with energy and time resolution simultaneously, and cannot be built up from a large number of shots. Time resolutions of the order of 1 nsec for pulse lengths of about 100 nsec make these requirements especially difficult. Some theoretical models are presented for the neutron output and its spectrum, but no self-consistent description of the plasma in the focus region is likely for some time. (author)

    2015-12-01

    Full Text Available Daylighting dynamism and constant change can characterize buildings and spaces with a living quality that cannot be achieved with any other design element. However, daylighting can create unwanted lighting conditions in the visual field causing discomfort and glare. This may affect the performance of building occupants such as workers or students. Consequently, designing for daylighting needs a good understanding of daylighting. Designers can rely on information from simulation software to re-imagine the space, especially to examine possible unexpected visual discomfort conditions.This paper aims to represent different visual comfort evaluation methods that can help decision-makers make better informed decisions. Different definitions and structures associated with daylight and glare are examined. It also presents a review of the literature of previous research conducted on daylighting, visual comfort analysis and glare studies.

    A software ecosystem is the interaction of a set of actors on top of a common technological platform that results in a number of software solutions or services. Arguably, software ecosystems are gaining importance with the advent of, e.g., the Google Android, Apache, and Salesforce.com ecosystems....... However, there exists no systematic overview of the research done on software ecosystems from a software engineering perspective. We performed a systematic literature review of software ecosystem research, analyzing 90 papers on the subject taken from a gross collection of 420. Our main conclusions...... are that while research on software ecosystems is increasing (a) there is little consensus on what constitutes a software ecosystem, (b) few analytical models of software ecosystems exist, and (c) little research is done in the context of real-world ecosystems. This work provides an overview of the field, while...

    A literature review was performed on intraoperative radiotherapy of breast cancer. The strength and attractiveness is established of techniques of partial irradiation in the treatment of breast cancer. The benefit is originated to restrict the area immediate of radiotherapy to the tumor bed or quadrant index and identifying the benefit of being applied during the radiotherapy while surgical lumpectomy. The impact of local recurrence has been established using intraoperative radiotherapy. The advantages of intraoperative radiotherapy was compared in the management of the conservative surgery in early stages of breast cancer with external radiotherapy. Different methods of intraoperative radiotherapy have been compared and individual impact on local recurrence ranges. Intraoperative radiotherapy has had many advantages: radiobiological, technical, clinical, psychological and economical in the handling of conservative surgery in early stages of breast cancer, compared with external radiotherapy [es

    Supernumerary teeth (ST) have been an anomaly of tooth development, this is refered to the increase in the number of pieces in the normal dentition. It can be unique, multiple, unilateral or bilateral, normal or altered form; appear erupted, impacted or retained. Both dentitions are affected, but is most common in the permanent. The literature review has covered and mentioned spanned supernumerary teeth, the definition, etiology, characteristics and classification according to number, position and shape; as diagnose, alterations or clinical sequelae - eruptive associated with them and possible treatments to be done when it occurs. The presence of mechanical accidents have been a frequent complication, within this, displacement of adjacent teeth has been the most common; is associated with different syndromes such as lip and palate cleft; however, they can not be related with pathologies; being mesiodens the most frequent.

    The society's image about the nurses is permeated of stereotypes that include figures like saints, prostitutes, witches, heroines and are related to the function of assisting doctors and to a lack of social life. Moreover, the image that the nurses have of themselves and of their work is negative, causing frustration for the lack of autonomy found on the professional reality. Seeking for a better understanding of this problem, a literature review was proceeded, aiming to characterize and analyze the nurse's image. The national scientific production is considered small on the subject. Conclusions indicate that stereotypes negatively influence nursing practice and that in Nursing history it is found many reasons for the existing distortions.

    A literature review was carried out focusing on the main factors associated with suicidal ideation, attempts and completed suicide in elders. The following databases were searched: MEDLINE, PsychINFO, SciELO and Biblioteca Virtual em Violência e Saúde da BIREME (BIREME's Violence and Health Virtual Library), referring to the period from 1980 to 2008. Fifty-two references were selected and analyzed. They showed a strong relationship among suicide ideation, attempt and completion in elderly individuals, which results from the interaction of complex physical, mental, neurobiological and social factors. Suicide associated with depression in the elderly can be prevented, provided the person is properly treated. In Brazil, it is necessary to invest in research, given the persistent increase in suicide rates among aged people, especially among males.

  19. Wipe sampling - review of the literature

    2011-01-01

    Methods for characterization of solid, non-compactable radioactive wastes contaminated in the surface are developed aiming at estimating the waste radioisotopic inventory for regulatory compliance and operational purposes. The wastes of interest here are mainly composed of plastic, metallic, or other materials parts originated in the decommissioning and maintenance operations of nuclear facilities. One way of measuring surface contamination is the indirect method of wiping the contaminated surface and counting the wipe, a common method of detecting non-fixed contamination in the radiation protection routine. The wipe sampling is an important tool in controlling the quality of the workplace in nuclear and radioactive facilities. Although radioprotection regulations establish quantitative limits, the practice in the radiation protection routine is to use wipe sampling as a qualitative measurement. To product useful quantitative results for inventorying radioactive wastes, a quantitative approach must be adopted. A previous paper presented by the authors in the last INAC Conference discussed alternative wipe materials and protocols. The method of wipe sampling underwent small changes since it started to be used but still is the object of study, as it is attested by many recent papers and patents on the subject. This article consists of a literature review. Results of a survey in the literature about wipe sampling techniques that can be applied to waste characterization are presented. (author)

    Numerous brands and types of artificial tears are available on the market for the treatment of dysfunctional tear syndrome. Past literature has focused on comparing the components of these products on patient’s clinical improvement. The wide array of products on the market presents challenges to both clinicians and patients when trying to choose between available tear replacement therapies. Different formulations affect patients based on etiology and severity of disease. In order to provide an unbiased comparison between available tear replacement therapies, we conducted a literature review of existing studies and National Institutes of Health clinical trials on commercially available, brand name artificial tears. Outcomes evaluated in each study, as well as the percent of patients showing clinical and symptomatic improvement, were analyzed. Fifty-one studies evaluating different brands of artificial tears, and their efficacy were identified. Out of the 51 studies, 18 were comparison studies testing brand name artificial tears directly against each other. Nearly all formulations of artificial tears provided significant benefit to patients with dysfunctional tear syndrome, but some proved superior to others. From the study data, a recommended treatment flowchart was derived. PMID:25114502

    Internet and particularly the so-called Web 2.0 are powerful tools of communication characterized by high user participation in the creation of content through various sites, such as those of social networking, where Facebook is the best known and most widely used. The aim of the present paper is to review the literature on the use of Facebook in health care. The international scientific literature of the past 10 years has been collected by major databases online. From the research were identified 262 articles of which 57 are considered relevant. The articles are schematically divided into three categories according to the topic: use of Facebook for psychosocial support for communication, for doctor-patient relationship, for institutional communication. The authors have identified the critical aspects and the possibility of using this tool in the communication and relationship between patients and health professionals. Despite the presence of critical issues, the use of social media is to be considered with interest and is worthy of study and research in the clinical setting. It should at the same time that health professionals are aware of the risks associated with the use of social networking but also trained in the use of the potential of these virtual tools that cannot replace real interactions but can support them.

  2. Energy storage: a review of recent literature

    Recent literature on the technological and economic status of reversible energy storage has been reviewed. A broad range of research and development activities have been pursued between 1975 and the present. Most of this work has concentrated on improving technical and economic performance of previously known storage technologies. Hydraulic pumped storage with both reservoirs above ground and compressed air storage (1 plant) are the only methods that have been adopted by electric utilities. The need for electrical energy storage in Canada has not been acute because of the large proportion of hydraulic generation which incorporates some storge and, in most cases, can readily be used for load-following. Residential heat storage in ceramic room heaters has been used in Europe for several years. For Canadian climatic and market conditions larger, central heating units would be required. Residential heat storage depends upon utilities offering time-of-use rates and none in Canada do so at present. Most seasonal storage concepts depend upon storage of low-grade heat for district heating. The cost of energy storage is highly dependent upon annual energy throughput and hence favours smaller capacity systems operating on frequent charge/discharge cycles over long-term storage. Capital costs of energy storage methods from the literature, expressed in constant dollars, are compared graphically and tentative investment costs are presented for several storage methods

    The study aimed to investigate the scientific literature on Public Humanization Policies, available in online periodicals, from 2009 to 2012, in the health field. This is an integrative literature review conducted in the Virtual Health Library databases: Latin-America and Caribbean Health Sciences (Lilacs) and the Scientific Electronic Library Online (SciELO) and Portal Capes. Data were collected in July 2013. To this end, the following Health Sciences Descriptors (DeCS) were used: "Humanization of Care," "Public Policies," "National Humanization Policy". The sample consisted of 27 articles about the investigated theme. From the publications selected for the research, three categories emerged according to their respective approaches: National Human-ization Policy: history and processes involved in its implementation; National Humanization Policy: health professionals contribution; Humanization and in the care process. The study showed that the National Humanization Policy is an important benchmark in the development of health practices. For this reason, there is a pressing multiplication of related reflections on ways to promote human-ization in health services.

    Patient satisfaction concept is widely measured due to its appropriateness to health service; however, evidence suggests that it is a poorly developed concept. This article is a first part of a two-part series of research with a goal to review a current conceptual framework of patient satisfaction and to bring the concept for further operationalisation procedures. The current article aimed to review a theoretical framework that helps the next article to review determinants of patient satisfaction for designing a measurement system. The study used a systematic review method, meta-narrative review, based on the RAMESES guideline with the phases of screening evidence, appraisal evidence, data extraction and synthesis. Patient satisfaction theoretical articles were searched on the two databases MEDLINE and CINAHL. Inclusion criteria were articles published between 1980 and 2014, and English language papers only. There were 36 articles selected for the synthesis. Results showed that most of the patient satisfaction theories and formulations are based on marketing theories and defined as how well health service fulfils patient expectations. However, review demonstrated that a relationship between expectation and satisfaction is unclear and the concept expectation itself is not distinctly theorised as well. Researchers brought satisfaction theories from other fields to the current healthcare literature without much adaptation. Thus, there is a need to attempt to define the patient satisfaction concept from other perspectives or to learn how patients evaluate the care rather than struggling to describe it by consumerist theories. © Royal Society for Public Health 2015.

    Staying current with the literature is of paramount importance to the pharmacist engaged in an evidence-based clinical practice. Given the expanding roles and responsibilities of today's pharmacists combined with exponential growth in new medical and health sciences literature, staying current has become an extremely daunting task. Traditional journal clubs have focused upon their role as a training vehicle for teaching critical reading skills to residents. However, schools of pharmacy are now required to provide instruction in biostatistics, research design, and interpretation. We present a paradigm shift in the traditional journal club model whereby a collection of periodicals is screened and a short synopsis of the pertinent articles is provided. The associated tasks for screening and presenting of the primary literature are shared among a group of clinicians and trainees with similar practice interests resulting in a more reasonable workload for the individual. This journal club method was effective in identifying a significant majority of articles judged to be pertinent by independent groups of clinicians in the same practice arenas. Details regarding the shared core practice and knowledge base elements, journal club format, identification of journals, and evaluation of the success of the journal club technique are provided.

    Spaceflight and the associated gravitational fluctuations may impact various components of the central nervous system. These include changes in intracranial pressure, the spine, and neurocognitive performance. The implications of altered astronaut performance on critical spaceflight missions are potentially significant. The current body of research on this important topic is extremely limited, and a comprehensive review has not been published. Herein, the authors address this notable gap, as well as the role of the neurosurgeon in optimizing potential diagnostic and therapeutic modalities. A literature search was conducted using the PubMed, EMBASE, and Google Scholar databases, with no time constraints. Significant manuscripts on physiologic changes associated with spaceflight and microgravity were identified and reviewed. Manifestations were separated into 1 of 3 general categories, including changes in intracranial pressure, the spine, and neurocognitive performance. A comprehensive literature review yielded 27 studies with direct relevance to the impact of microgravity and spaceflight on nervous system physiology. This included 7 studies related to intracranial pressure fluctuations, 17 related to changes in the spinal column, and 3 related to neurocognitive change. The microgravity environment encountered during spaceflight impacts intracranial physiology. This includes changes in intracranial pressure, the spinal column, and neurocognitive performance. Herein, we present a systematic review of the published literature on this issue. Neurosurgeons should have a key role in the continued study of this important topic, contributing to both diagnostic and therapeutic understanding. Copyright © 2017 Elsevier Inc.

    Full Text Available The purpose of this review was to inform all medical health care professionals about cuboid syndrome, which has been described as difficult to recognize and is commonly misdiagnosed, by explaining the etiology of this syndrome, its clinical diagnosis in relation to differential diagnoses, commonly administered treatment techniques, and patient outcomes. A comprehensive review of the relevant literature was conducted with MEDLINE, EBSCO, and PubMed (1960 - Present using the key words cuboid, cuboid syndrome, foot anatomy, tarsal bones, manual therapy, and manipulation. Medical professionals must be aware that any lateral foot and ankle pain may be the result of cuboid syndrome. Once properly diagnosed, cuboid syndrome responds exceptionally well to conservative treatment involving specific cuboid manipulation techniques. Other methods of conservative treatment including therapeutic modalities, therapeutic exercises, padding, and low dye taping techniques are used as adjuncts in the treatment of this syndrome. Immediately after the manipulation is performed, the patient may note a decrease or a complete cessation of their symptoms. Occasionally, if the patient has had symptoms for a longer duration, several manipulations may be warranted throughout the course of time. Due to the fact radiographic imaging is of little value, the diagnosis is largely based on the patient's history and a collection of signs and symptoms associated with the condition. Additionally, an understanding of the etiology behind this syndrome is essential, aiding the clinician in the diagnosis and treatment of this syndrome. After the correct diagnosis is made and a proper treatment regimen is utilized, the prognosis is excellent

    Despite all the investment in research, uncertainty persists in anticipatory grief (AG) literature, concerning its nuclear characteristics and definition. This review aimed to synthesize recent research in order to develop further knowledge about the family experience of AG during a patient's end of life. An integrative review was performed using standard methods of analysis and synthesis. The electronic databases Medline, Web of Knowledge, and EBSCO and relevant journals were systematically searched since 1990 to October 2015. Twenty-nine articles were selected, the majority with samples composed of caregivers of terminally ill patients with cancer. From systematic comparison of data referring to family end-of-life experience emerged 10 themes, which correspond to AG nuclear characteristics: anticipation of death, emotional distress, intrapsychic and interpersonal protection, exclusive focus on the patient care, hope, ambivalence, personal losses, relational losses, end-of-life relational tasks, and transition. For the majority of family caregivers in occidental society, AG is a highly stressful and ambivalent experience due to anticipation of death and relational losses, while the patient is physically present and needed of care, so family must be functional and inhibit grief expressions. The present study contributes to a deeper conceptualization of this term and to a more sensitive clinical practice.

    The purpose of this paper is to explore approaches to the regulation of healthcare complaints and disciplinary processes. A literature review was conducted across Medline, Sociological Abstracts, Web of Science, Google Scholar and the health, law and social sciences collections of Informit, using terms tapping both the complaints process and regulation generally. A total of 118 papers dealing with regulation of health complaints or disciplinary proceedings were located. The review reveals a shift away from self-regulation towards greater external oversight, including innovative regulatory approaches including "networked governance and flexible or "responsive" regulation. It reports growing interest in adoption of strategic and responsive approaches to health complaints governance, by rejecting traditional legal forms in favor of more strategic and responsive forms, taking account of the complexity of adverse health events by tailoring responses to individual circumstances of complainants and their local environments. The challenge of how to collect and harness complaints data to improve the quality of healthcare at a systemic level warrants further research. Scope also exists for researching health complaints commissions and other "meta-regulatory" bodies to explore how to make these processes fairer and better able to meet the complex needs of complainants, health professionals, health services and society.

    Objective: To describe the MRI features of nodular fasciitis and to review the clinical, MRI and histologic aspects of the tumor. Design and patients: Three patients with biopsy-proven nodular fasciitis were selected for a retrospective study. A literature review was also carried out. Results and conclusions: All the lesions appeared slightly hyperintense to skeletal muscle on T1-weighted images, and hyperintense on T2-weighted images with fat saturation [either frequency saturation or Short TI Inversion Recovery (STIR) sequences]. Two enhanced homogeneously after intravenous gadolinium, whereas the third showed heterogeneous enhancement with a nonenhancing area. Despite the difference in enhancing patterns, the histologic appearances of these lesions were similar. Our study shows that the MRI appearance of nodular fasciitis may not be related to the location of lesion. It is thought that the age of nodular fasciitis may reflect its gross morphology, and it is possible that the MRI and histologic appearances could correlate with the age of the lesion, but it would require a larger series to evaluate this concept.

    Pront, Leeanne; Müller, Amanda; Koschade, Adam; Hutton, Alison

    The aim of this research was to investigate videogame-based learning in nursing education and establish how videogames are currently employed and how they link to the development of decision-making, motivation, and other benefits. Although digital game-based learning potentially offers a safe and convenient environment that can support nursing students developing essential skills, nurse educators are typically slow to adopt such resources. A comprehensive search of electronic databases was conducted, followed by a thematic analysis of the literature. Evaluations of identified games found generally positive results regarding usability and effectiveness of videogames in nursing education. Analysis of advantages of videogames in nursing education identified potential benefits for decision-making, motivation, repeated exposure, logistical, and financial value. Despite the paucity of games available and the methodological limitations identified, findings provide evidence to support the potential effectiveness of videogames as a learning resource in nursing education.

    Full Text Available Cameron syndrome is the ulcerative or erosive lesions of mucosal layer at the sac of hiatal hernia which can cause chronic occult or overt bleeding and iron-deficiency anemia. Hiatal hernia is a relatively frequent finding, which is in most cases asymptomatic or manifested by dyspeptic symptoms of varying severity. Despite of being a very important association of hiatal hernia Cameron syndrome is not widely represented in medical literature. That`s the reason of a lack of awareness among physicians, surgeons and endoscopists about that pathology. Cameron lesions are significant pathology because they can become a source of chronic occult as well as an acute life-threatening bleeding. Those lesions of upper gastrointestinal tract are often misinterpreted or overlooked during standard diagnostic procedures. It can lead to the misdiagnosis and false ways of treatment. The review focuses on the pathogenesis, main diagnostic problems and treatment options of that pathology. The diagnostics of the Cameron syndrome is difficult because sometimes the lesions can`t be seen on upper gastrointestinal tract endoscopy. The review describes the criteria by which the physician may suspect Cameron syndrome when endoscopy results are not certain. Clinical case represents an important problem which is often faced by the doctors — the severe iron-deficiency anemia refractory to the medication and blood transfusions in the patients with Cameron lesions. It`s very important for doctor to be aware of that complication to include Cameron syndrome into the diagnostic search for the sources of persistent blood loss. Cameron lesions can be asymptomatic as well as be manifested in the form of severe chronic anemia. And that`s the reason why there are an important issue about the proper treatment which have to be provided in each case. The review describes the effectiveness of different treatment options and makes the conclusion about the principles on which doctor can

    Full Text Available Performance evaluation of an economic entity requires approaching several criteria, such as industry and economic entity type, managerial and entrepreneurial strategy, competitive environment, human and material resources available, using a system of appropriate performance indicators for this purpose.The exigencies of communication occurred on the growing number of phenomena that marked the global economy in recent decades (internationalization and relocation of business crises and turmoil in financial markets, demand performance measurement to be made in a comprehensive way by financial and non-financial criteria. Indicators are measures of performance used by management to measure, report and improve performance of the economic entity. The relationship between indicators and management is ensured by the existence of performance measurement systems. Studies to date indicate that economic entities using balanced performance measurement systems as a key management tool registered superior performance compared to entities not using such systems. This study attempts to address the issue of performance evaluation by presenting opinions of different authors concerning the process of performance measurement and to present, after revising the literature, the evolution of the performance evaluation systems. We tried to do this literature review because sustainable development and, therefore, globalization require new standards of performance that exceeds the economic field, both for domestic companies as well as international ones. So, these standards should be integrated into corporate strategy development to ensure sustainability of activities undertaken by harmonizing the economic, social and environmental objectives. To assess the performance of economic entities it is required that performance evaluation to be done with a balanced multidimensional system, including both financial ratios and non-financial indicators in order to reduce the limits of

    Full Text Available The term corporate reputation has been mentioned in academic papers for some decades however since the 90's the debate about it has been intensified by authors of different areas of study. Therefore, there is a growing pressure around the definition of a construct and the way to measure an organization's corporate reputation. The purpose of this article is to present a literature review on corporate reputation in three different perspectives. At first, we intended to go through the literature, pointing out the different definitions presented on this theme. The second aspect refers to the identification of terms related to corporate reputation, such as corporate brand, corporate identity and corporate communication. Finally, broadening the possibilities of future empiric works, a review of the different proposals of measuring the corporate reputation of organizations is made.O tema reputação corporativa tem sido objeto de estudos acadêmicos há algumas décadas, porém, somente a partir da década de 90 intensificou-se esse interesse, manifestado por autores de diferentes áreas de estudo. A diversidade de abordagens pressiona o debate sobre a definição de um constructo e sobre a forma mais adequada de mensuração da reputação corporativa de uma organização. O propósito deste artigo é realizar uma revisão da literatura sobre a questão da reputação corporativa em três perspectivas distintas. Pretende-se, em primeiro lugar, percorrer a literatura sobre o assunto, apontando as diferentes definições apresentadas do tema.

    2018-01-01

    The majority of the reviews and studies on chronic pain in pregnancy have primarily focused on the pharmacological and non-pharmacological treatment options. The purpose of our review was to identify evidence-based clinical research for the evaluation and management of preexisting chronic pain in pregnancy, chronic pain associated with pregnancy, and chronic pain in relation to mode of delivery. A literature search was undertaken using the search engines PubMed, CINAHL, EBSCOhost, and Web of Science. Search terms used included "chronic pain" AND "pregnant OR pregnancy" OR "pregnancy complications" from inception through August 2016. The basis of this review was the 144 articles that met inclusion criteria for this review. Based on our review of the current literature, we recommend 7 guidelines for chronic pain management during and after pregnancy: 1) complete history and physical examination; 2) monitor patients for alcohol, nicotine, and substance use; 3) collaborate with patient to set treatment goals; 4) develop a management plan; 5) for opioids, use lowest effective dose; 6) formulate a pain management plan for labor and delivery; and 7) discuss reproductive health with women with chronic pain. The management of chronic pain associated with pregnancy is understudied. Obstetrical providers primarily manage chronic pain during pregnancy. Some general guidelines are provided for those health care providers until more information is available.

  20. Workplace stress in nursing: a literature review.

    Science.gov (United States)

    McVicar, Andrew

    2003-12-01

    Stress perception is highly subjective, and so the complexity of nursing practice may result in variation between nurses in their identification of sources of stress, especially when the workplace and roles of nurses are changing, as is currently occurring in the United Kingdom health service. This could have implications for measures being introduced to address problems of stress in nursing. To identify nurses' perceptions of workplace stress, consider the potential effectiveness of initiatives to reduce distress, and identify directions for future research. A literature search from January 1985 to April 2003 was conducted using the key words nursing, stress, distress, stress management, job satisfaction, staff turnover and coping to identify research on sources of stress in adult and child care nursing. Recent (post-1997) United Kingdom Department of Health documents and literature about the views of practitioners was also consulted. Workload, leadership/management style, professional conflict and emotional cost of caring have been the main sources of distress for nurses for many years, but there is disagreement as to the magnitude of their impact. Lack of reward and shiftworking may also now be displacing some of the other issues in order of ranking. Organizational interventions are targeted at most but not all of these sources, and their effectiveness is likely to be limited, at least in the short to medium term. Individuals must be supported better, but this is hindered by lack of understanding of how sources of stress vary between different practice areas, lack of predictive power of assessment tools, and a lack of understanding of how personal and workplace factors interact. Stress intervention measures should focus on stress prevention for individuals as well as tackling organizational issues. Achieving this will require further comparative studies, and new tools to evaluate the intensity of individual distress.

    2009-04-01

    Many acute inpatient psychiatric wards in the UK are permanently locked, although this is contrary to the current Mental Health Act Code of Practice. To conduct a literature review of empirical articles concerning locked doors in acute psychiatric inpatient wards, an extensive literature search was performed in SAGE Journals Online, EBM Reviews, British Nursing Index, CINAHL, EMBASE Psychiatry, International Bibliography of the Social Sciences, Ovid MEDLINE, PsycINFO and Google, using the search terms 'open$', 'close$', '$lock$', 'door', 'ward', 'hospital', 'psychiatr', 'mental health', 'inpatient' and 'asylum'. A total of 11 empirical papers were included in the review. Both staff and patients reported advantages (e.g. preventing illegal substances from entering the ward and preventing patients from absconding and harming themselves or others) and disadvantages (e.g. making patients feel depressed, confined and creating extra work for staff) regarding locked doors. Locked wards were associated with increased patient aggression, poorer satisfaction with treatment and more severe symptoms. The limited literature available showed the urgent need for research to determine the real effects of locked doors in inpatient psychiatry.

    2014-04-01

    Full Text Available Restoration of the quality of life (QoL of trauma injury survivors is the aim of trauma rehabilitation. It is generally acknowledged that sexuality is an important component of QoL; however, rehabilitation services frequently fall short of including sexuality as a matter of routine. The literature was reviewed to examine the experiences of trauma survivors from three groups: spinal cord injury (SCI, traumatic brain injury (TBI and burns. The focus was on the impact of trauma on the QoL to identify future research directions and to advocate for the inclusion of sexuality as an integral part of rehabilitation. Databases searched were Proquest, Ovid, Cinahl, Medline, PsycInfo and Cochrane Central Register of controlled trials. A total of 36 eligible studies were included: SCI (n = 25, TBI (n = 6, burns (n = 5. Four themes were identified across the three trauma groups that were labeled as physiological impact of trauma on sexuality, cognitive-genital dissociation (CGD, sexual disenfranchisement (SD and sexual rediscovery (SR. Trauma injury has a significant impact on sexuality, which is not routinely addressed within rehabilitation services. Further sexuality research is required among all trauma groups to improve rehabilitation services and in turn QoL outcomes for all trauma survivors.

  5. Idaho radionuclide exposure study: Literature review

    1987-10-01

    Phosphate ores contain elevated levels of natural radioactivity, some of which is released to the environment during processing or use of solid byproducts. The effect of radionuclides from Idaho phosphate processing operations on the local communities has been the subject of much research and study. The literature is reviewed in this report. Two primary radionuclide pathways to the environment have been studied in detail: (1) airborne release of volatile radionuclides, primarily 210 Po, from calciner stacks at the two elemental phosphorus plants; and (2) use of byproduct slag as an aggregate for construction in Soda Springs and Pocatello. Despite the research, there is still no clear understanding of the population dose from radionuclide emissions, effluents, and solid wastes from phosphate processing plants. Two other potential radionuclide pathways to the environment have been identified: radon exhalation from phosphogypsum and ore piles and contamination of surface and ground waters. Recommendations on further study needed to develop a data base for a complete risk assssment are given in the report

  6. Pituicytoma. Case report and literature review

    Directory of Open Access Journals (Sweden)

    Fernando Velandia Hurtado

    2018-04-01

    Full Text Available Pituicytoma is a rare glial tumour located in the sellar and/or suprasellar region of the brain, it originates from pituicytes, and they were included in the World Health Organization (WHO Classification of Central Nervous System Tumours in 2017. As mentioned above it originates from pituicytes cells in the posterior pituitary near the infundibulum. Histological characteristics permits classification and identification among other central nervous system tumours localized in the posterior pituitary or infundibulum. WHO classification describes them as grades such as grade I tumour which has a differentiated structure composed of spindle-shaped cells presumably derived from pituicytes. We report the case of a 37-year-old woman who developed a suprasellar tumour and that it was discovered following a past medical history of amenorrhoea and migraines. Once the lesion was detected in images, the patient rejected surgical treatment even when she developed galactorrhea and preferred medical treatment with cabergoline. However, two years later she developed visual defects due to increase in size by that time accepting surgical treatment. A review of the literature including most common clinical and radiological features of this entity as well as treatment protocols proposed are discussed.

  7. Microbial-influenced cement degradation: Literature review

    International Nuclear Information System (INIS)

    Rogers, R.D.; Hamilton, M.A.; McConnell, J.W. Jr.

    1993-03-01

    The Nuclear Regulatory Commission stipulates that disposed low-level radioactive waste (LLW) be stabilized. Because of apparent ease of use and normal structural integrity, cement has been widely used as a binder to solidify LLW. However, the resulting waste forms are sometimes susceptible to failure due to the actions of waste constituents, stress, and environment. This report reviews literature which addresses the effect of microbiologically influenced chemical attack on cement-solidified LLW. Groups of microorganisms are identified, which are capable of metabolically converting organic and inorganic substrates into organic and mineral acids. Such acids aggressively react with concrete and can ultimately lead to structural failure. Mechanisms inherent in microbial-influenced degradation of cement-based material are the focus of this report. This report provides sufficient evidence of the potential for microbial-influenced deterioration of cement-solidified LLW to justify the enumeration of the conditions necessary to support the microbiological growth and population expansion, as well as the development of appropriate tests necessary to determine the resistance of cement-solidified LLW to microbiological-induced degradation that could impact the stability of the waste form

  8. Cesium and Strontium Separation Technologies Literature Review

    2004-03-01

    Integral to the Advanced Fuel Cycle Initiative (AFCI) Program’s proposed closed nuclear fuel cycle, the fission products cesium and strontium in the dissolved spent nuclear fuel stream are to be separated and managed separately. A comprehensive literature survey is presented to identify cesium and strontium separation technologies that have the highest potential and to focus research and development efforts on these technologies. Removal of these high-heat-emitting fission products reduces the radiation fields in subsequent fuel cycle reprocessing streams and provides a significant short-term (100 yr) heat source reduction in the repository. This, along with separation of actinides, may provide a substantial future improvement in the amount of fuel that could be stored in a geologic repository. The survey and review of the candidate cesium and strontium separation technologies are presented herein. Because the AFCI program intends to manage cesium and strontium together, technologies that simultaneously separate both elements are of the greatest interest, relative to technologies that separate only one of the two elements.

  9. Allosensibilisation to erythrocyte antigens (literature review

    N. V. Mineeva

    2015-01-01

    Full Text Available In this article literature review of the causes of allosensibilisation to erythrocyte antigens are presented. It is shown that the ability to produce antierythrocyte antibodies is affected by many factors, principal of whom it is difficult to identify. For the allosensibilisation development requires genetically determined differences in erythrocyte antigens phenotypes of donor and recipient, mother and fetus, which can lead to immune response and antibodies production. The biochemical nature of erythrocyte antigens, antigen dose (the amount of transfused doses, the number of antigens determinants on donor and fetus erythrocytes, the number of pregnancies are important. Individual patient characteristics: age, gender, diseases, the use of immunosuppressive therapy and the presence of inflammatory processes, are also relevant. Note that antibody to one erythrocyte antigens have clinical value, and to the other – have no. The actual data about frequency of clinically significant antibodies contribute to the development of post-transfusion hemolytic complications prophylaxis as well as the improvement of laboratory diagnosis of hemolytic disease of the newborn in the presence of maternal antierythrocyte antibodies.

    2017-09-01

    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.

    More than a century ago, Ortner described a case of cardiovocal syndrome wherein he attributed a case of left vocal fold immobility to compression of the recurrent laryngeal nerve by a dilated left atrium in a patient with mitral valve stenosis. Since then, the term Ortner's syndrome has come to encompass any nonmalignant, cardiac, intrathoracic process that results in embarrassment of either recurrent laryngeal nerve-usually by stretching, pulling, or compression; and causes vocal fold paralysis. Not surprisingly, the left recurrent laryngeal nerve, with its longer course around the aortic arch, is more frequently involved than the right nerve, which passes around the subclavian artery. To discuss the pathogenesis of hoarseness resulting from cardiovascular disorders involving the recurrent laryngeal nerve along with the findings of literature review. This paper reports a series of four cases of Ortner's syndrome occurring due to different causes. Case study. Ortner's syndrome could be a cause of hoarseness of voice in patients with cardiovascular diseases. Although hoarseness of voice is frequently encountered in the Otolaryngology outpatient department, cardiovascular- related hoarseness is an unusual presentation. Indirect laryngoscopy should be routinely performed in all cases of heart disease.

    Mansueto, Pasquale; Seidita, Aurelio; Vitale, Giustina; Cascio, Antonio

    2014-01-01

    Leishmaniasis is a vector-borne protozoan infection whose clinical spectrum ranges from asymptomatic infection to fatal visceral leishmaniasis. Over the last decades, an increase in imported leishmaniasis cases in developed, non-endemic countries, have been pointed-out from a review of the international literature. Among the possible causes are increasing international tourism, influx of immigrants from endemic regions and military operations. The main area for the acquisition of cutaneous leishmaniasis, especially for adventure travelers on long-term trips in highly-endemic forested areas, is represented from South America, whereas popular Mediterranean destinations are emerging as the main areas to acquire visceral variant. Leishmaniasis should be considered in the diagnostic assessment of patients presenting with a compatible clinical syndrome and a history of travel to an endemic area, even if this occurred several months or years before. Adventure travelers, researchers, military personnel, and other groups of travelers likely to be exposed to sand flies in endemic areas, should receive counseling regarding leishmaniasis and appropriate protective measures.

    Atrial fibrillation is the most common arrhythmia worldwide with increasing frequency noted with age. Hyperthyroidism is a well-known cause of atrial fibrillation with a 16%-60% prevalence of atrial fibrillation in patients with known hyperthyroidism Ross et al. (2016). While hyperthyroidism as a causative factor of atrial fibrillation is well established, this literature review aims to answer several questions on this topic including: 1. The relationship of atrial fibrillation to hyperthyroidism 2. Atrial fibrillation as a predictor of hyperthyroidism 3. The pathophysiology of thyrotoxic atrial fibrillation 4. Subclinical hyperthyroidism and the relationship with atrial fibrillation 5. Cardioversion and Catheter ablation of hyperthyroid patients with atrial fibrillation 6.

  14. Evidence-based management: a literature review.

    Science.gov (United States)

    Young, Sam K

    2002-05-01

    This paper presents a review of evidence-based management (EBM), exploring whether management activities within healthcare have been, or can be, subject to the same scientific framework as clinical practice. The evidence-based approach was initially examined, noting the hierarchy of evidence ranging from randomized control trials to clinical anecdote. The literature varied in its degree of criticism of this approach; the most common concern referring to the assumed superiority of positivism. However, evidence-based practice was generally accepted as the best way forward. Stewart (1998) offered the only detailed exposition of EBM, outlining a necessary 'attitude of mind' both for EBM and for the creation of a research culture. However, the term 'clinical effectiveness' emerged as a possible replacement buzz-word for EBM (McClarey 1998). The term appears to encompass the sentiments of the evidence-based approach, but with a concomitant concern for economic factors. In this paper the author has examined the divide between those who viewed EBM as an activity for managers to make their own practice accountable and those who believed it to be a facilitative practice to help clinicians with evidence-based practice. Most papers acknowledged the limited research base for management activities within the health service and offered some explanation such as government policy constraints and lack of time. Nevertheless, the overall emphasis is that ideally there should be a management culture firmly based in evidence.

  15. Firefighters' noise exposure: A literature review

    Directory of Open Access Journals (Sweden)

    Taxini, Carla Linhares

    2013-01-01

    Full Text Available Aim: To review the literature about the effects of environmental noise on the hearing ability of firefighters. Method: The PubMed and Scielo databases were searched and studies from 2002 to 2012 that included the keywords firefighters, noise, and hearing loss were identified. Initially, 24 studies were selected, but only 10 met the inclusion criteria of investigating the effects of occupational noise on firefighters. Results: Only 2 (20% studies quantified levels of sound pressure and performed audiological tests to identify associations with noise intensity and 3 (30% questionnaire-based studies reported that these professionals are more susceptible to hearing loss. Four (50% studies found that noise exposure damages the auditory system in this population. Discussion: These findings indicate that there is a necessity for preventive measures to be adopted by this population since it is considered to be at risk. Conclusion: In recent years, there have been few studies of firefighters' exposure to occupational noise, but our findings show the importance of new studies that include proper means of quantifying their exposure to noise in different work environments, in order to identify possible adverse conditions as well as to aid in the diagnosis of hearing loss.

    2013-01-01

    Full Text Available Background Brucellosis is a multisystem disease which may present with a broad spectrum of clinical manifestations and complications. Neurobrucellosis is an uncommon complication of this infection. This article aims to present clinical manifestations and to discuss the clinical features and management of 3 neurobrucellosis cases. Methods The diagnosis, treatment, laboratory results and accessory examination findings of 3 patients with neurobrucellosis between August 2010 and March 2012 were retrospectively analyzed, and relevant literature was reviewed. Results All the 3 cases had definite history of exposure to epidemic areas or infectious diseases, and history of being infected with Brucella by drinking raw milk. During the screening because of fever for reasons unknown, they were proved to be infected with Brucella by etiological or serological tests. Initial clinical manifestations consisted of fever and headache, with meningitis symptoms and signs, spondylitis, uroschesis and constipation (which might be caused by lumbosacral nerve root lesion, or neurological manifestations in auditory nerve and abducent nerve, such as hearing loss and diplopia. All patients were treated with rifampicin, doxycycline plus trimethoprim-sulfamethoxazole or ceftriaxone. Conclusion Neurobrucellosis presents with various clinical signs and symptoms, and is often accompanied by systemic infection. Brucellosis should be kept in mind during the screening of fever for reasons unknown, and be differentiated from Mycobacterium tuberculosis infection. The combined treatment by antibotics of different pharmacological mechanisms with full dose and long range is effective, and the prognosis is favorable.

    Manfrin-Ledet, Linda; Porche, Demetrius J; Eymard, Amanda S

    2015-06-01

    The purpose of this article is to review the nursing literature related to professional boundary violations in nursing. A search was conducted using CINAHL, MEDLINE, Ebscohost, and NCSBN. The key words searched were professional boundaries, boundary violation, boundary crossings, nurse, home health nurses, and home nursing. The search returned over 40 publications related specifically to boundary violations and nursing although only four of them are published research studies and one as a dissertation. Seven common characteristics emerged from the nonresearch nursing articles on professional boundaries: (1) Dual relations/role reversal, (2) Gifts and money, (3) Excessive self-disclosure, (4) Secretive behavior, (5) Excessive attention/overinvolvement, (6) Sexual behavior, and (7) Social media. Additional nursing research is greatly needed in the area of professional boundaries. The nurse-patient relationship should always be maintained for the benefit of the patient and not the personal gain of the nurse. Ongoing education in nursing practice regarding professional boundaries is needed. Nurses need to be mindful of state practice acts, codes of conduct, and employer policies.

  18. Income Elasticity Literature Review | Science Inventory | US ...

    Science.gov (United States)

    Following advice from the SAB Council, when estimating the economic value of reductions in air pollution-related mortality and morbidity risk, EPA accounts for the effect of personal income on the willingness to pay to reduce the risk of adverse health outcomes. These income growth adjustment factors are calculated using a combination of income elasticity estimates and income growth projections, both of which have remained essentially unchanged since 1999. These income elasticity estimates vary according to the severity of illness. EPA recently received advice from the SAB regarding the range of income elasticities to apply as well as the research standards to use when selecting income elasticity estimates. Following this advice, EPA consulted with a contractor to update its income elasticity and income growth projections, and generate new income growth adjustment factors. The SAB would evaluate the income elasticity estimates identified in the EPA-provided literature review, determining the extent to which these estimates are appropriate to use in human health benefits assessments.

    Giovannopoulou, Eirini; Gkasdaris, Grigorios; Kapetanakis, Stylianos; Kontomanolis, Emmanuel

    2017-01-01

    Ankylosing Spondylitis (AS) is the prototype of a group of systemic rheumatic diseases collectively referred to as Spondylarthitides (SpA). It has now become clear that AS is not as rare as previously thought and, although it has an early onset in life affecting patients in their reproductive years, it has not been proved to adversely affect fertility in females. The aim of this review is to summarize all the recent data on AS and pregnancy in terms of fertility, disease course and pregnancy outcome from a clinical perspective. A literature research was conducted based on the following medical databases: Pubmed/ Medline and the Cochrane Library. We searched for randomized controlled studies, casecontrol studies, cohort studies, patient and drug registers in relation to pregnancy and AS. The existing data do not support a causal relationship between AS and infertility. The state of pregnancy is not associated with reduced disease activity in patients with AS. Additionally, AS tends to adversely affect health-related quality of life during pregnancy, in comparison with normal population and patients with rheumatoid arthritis. As far as the obstetrical outcome is concerned, there is no consensus on the significant association between AS and specific pregnancy, delivery and fetal complications. Previous studies are highly heterogenous and mainly retrospective and thus, the existing data are controversial and inconclusive. Subsequent studies are required to enlighten our knowledge on the interaction between AS and pregnancy.

  20. Mild Primary Hyperparathyroidism: A Literature Review

    Science.gov (United States)

    Applewhite, Megan K.

    2014-01-01

    The biochemical profile of classic primary hyperparathyroidism (pHPT) consists of both elevated calcium and parathyroid hormone levels. The standard of care is parathyroidectomy unless prohibited by medical comorbidities. Because more patients are undergoing routine bone density evaluation and neck imaging studies for other purposes, there is a subset of people identified with a biochemically mild form of the pHPT that expresses itself as either elevated calcium or parathyroid hormone levels. These patients often do not fall into the criteria for operation based on the National Institutes of Health consensus guidelines, and they can present a challenge of diagnosis and management. The purpose of this paper is to review the available literature on mild pHPT in an effort to better characterize this patient population and to determine whether patients benefit from parathyroidectomy. Evidence suggests that there are patients with mild pHPT who have overt symptoms that are found to improve after parathyroidectomy. There is also a group of patients with biochemically mild pHPT who are found to progress to classic pHPT over time; however, it is not predictable which group of patients this will be. Early intervention for this group with mild pHPT may prevent progression of bone, psychiatric, and renal complications, and parathyroidectomy has proven safe in appropriately selected patients at high volume centers.

    2016-09-01

    A review of the current literature evaluating trauma nursing education. A variety of trauma nursing courses exist, to educate nurses working in trauma settings, and to maintain their continuing professional development. Despite an increase in the number of courses delivered, there appears to be a lack of evidence to demonstrate the effectiveness of trauma nursing education and in particular the justification for this resource allocation. Integrative literature review. A search of international literature on trauma nursing education evaluation published in English from 1985 to 2015 was conducted through electronic databases CINAHL Plus, Google Scholar, PubMed, Austhealth, Science Citation Index Expanded (Web of Science), Sciverse Science Direct (Elsevier) & One file (Gale). Only peer reviewed journal articles identifying trauma course and trauma nursing course evaluation have been included in the selection criteria. An integrative review of both quantitative and qualitative literature guided by Whittemore and Knafl's theoretical framework using Bowling's and Pearson's validated appraisal checklists, has been conducted for three months. Only 17 studies met the inclusion criteria, including 14 on trauma course evaluation and 3 on trauma nursing course evaluation. Study findings are presented as two main themes: the historical evolution of trauma nursing education and evaluation of trauma nursing education outcomes. Trauma nursing remains in its infancy and education in this specialty is mainly led by continuing professional development courses. The shortage of evaluation studies on trauma nursing courses reflects the similar status in continuing professional development course evaluation. A trauma nursing course evaluation study will address the gap in this under researched area. Copyright © 2016 Elsevier Ltd. All rights reserved.

  2. Review of current drive theory: selected topics

    International Nuclear Information System (INIS)

    Fisch, N.J.

    1993-01-01

    Two themes in current drive theory in tokamaks are reviewed, both relevant to the progression of tokamak experiments toward the reactor regime. First, the physics of the tail electrons is reviewed. These electrons are capable of carrying enormous rf-driven electric current, and, in the course of current-drive experiments worldwide not only has the current drive effect been demonstrated, but the underlying physical description of these tail electrons has been established. Second, anticipating the presence of the energetic alpha particles that result from D-T reactions in a reactor, certain mechanisms through which these alpha particles can be used to facilitate current-drive are reviewed.

    2008-01-01

    Full Text Available Non-carious cervical lesions are characterized by structural loss near the cementoenamel junction, without the presence of caries. Anumber of theories have arisen to explain the etiology of such lesions, although the real causes remain obscure, as is reflected by the contradictory terminology used in the literature. In addition to describing acidic and abrasive processes documented as etiological factors, attention is given to the role of mechanical stress from occlusal load, which is the most accepted theory for the development of abfraction lesions. Considering that tensile stress leads to the failure of restorations in the cervical region and that this is a fruitful area for future research, the present study has highlighted diagnosis, prognosis and the criteria for treatment.

    2017-10-01

    Enhanced Recovery Pathways (ERPs) are an increasingly popular, evidenced-based approach to surgery, designed to improve patient outcomes and reduce costs. Despite evidence demonstrating the benefits of these pathways, implementation and adherence have been inconsistent. Using realist synthesis, this review explored the current literature surrounding the implementation of ERPs in the UK. Knowledge consolidation between authors and consulting with field experts helped to guide the search strategy. Relevant medical and social science databases were searched from 2000 to 2016, as well as a general web search. A total of 17 papers were identified, including original research, reviews, case studies and guideline documents. Full texts were analysed, cross-examined, and data extracted and synthesised. Several implementation strategies were identified, including the contexts in which these operated, the subsequent mechanisms of action that were triggered, and the outcome patterns they produced. Context-Mechanism-Outcome (CMO) configurations were generated, tested, and refined. These were grouped to develop two programme theories concerning ERP implementation, one related to the strategy of consulting with staff, the other with appointing a change agent to coordinate and drive the implementation process. These theories highlight instances in which implementation could be improved. Current literature in ERP research is primarily focussed on measuring patient outcomes and cost effectiveness, and as a result, important detail regarding the implementation process is often not reported or described robustly. This review not only provides recommendations for future improvements in ERP implementation, but also highlights specific areas of focus for furthering ERP implementation research.

    Full Text Available Instructors across the disciplines require their students to write literature reviews. Although numerous sources describe the literature review process, instructors and students face difficulty when approaching the structure of a literature review. This paper presents a straightforward, efficient approach for teaching students how to write a literature review. Developed over the course of three years at a university writing center, this lesson received substantial support from students across the disciplines. This paper reflects on one group of students’ experiences while writing literature reviews in a political science course, showing that students demonstrated a sense of confidence and direction after the lesson. University professors, writing center staff, and content-discipline instructors in higher education classrooms can alleviate their students’ anxiety about literature reviews by using this lesson in their classrooms.

    Full Text Available Manifestations of sexism are under the constant influence of social changes and changes in gender relations. This paper presents modern forms of sexism, with an emphasis on the ambivalent sexism theory (Glick and Fiske, 1996. Ambivalent sexism theory addresses sexism not only on societal but also on interpersonal and personal level. In addition, this article provides a comprehensive review of the empirical findings in the field of benevolent and hostile sexism and their effect on close relations, sexual violence, beauty ideals and practices, women’s self-esteem, and their career decisions and aspirations. Finally, I place ambivalent sexism theory into the broader societal and psychological context and discuss the possibilities of surmounting current sexist ideologies and practices.

    Over the years, increasing numbers of children and adolescents have sought help for acute psychiatric problems. The responses to this treatment-seeking behavior are heterogeneous in different settings and nations. This review aimed to provide an answer to the questions "which care should be offered to children and adolescents presenting with a psychiatric emergency or crisis and how should it be organized." We committed a literature review to find out if any recommendations can be made regarding the organization of emergency care for children and adolescents with acute mental health problems. The lack of a clear definition of emergencies or urgencies hampered this review; we note the differences between adult and child or adolescent psychiatry. The theoretical models of care found in the literature are built up from several process and structural components, which we describe in greater detail. Furthermore, we review the main service delivery models that exist for children and adolescents. Currently, emergency psychiatric care for children and adolescents is practiced within a wide range of care models. There is no consensus on recommended care or recommended setting for this population. More research is needed to make exact recommendations on the standardization of psychiatric care for young people in emergency settings.

    2012-01-01

    Pancreatic surgery represents one of the most challenging areas in digestive surgery. In recent years, an increasing number of laparoscopic pancreatic procedures have been performed and laparoscopic distal pancreatectomy (LDP) has gained world-wide acceptance because it does not require anastomosis or other reconstruction. To date, English literature reports more than 300 papers focusing on LDP, but only 6% included more than 30 patients. Literature review confirms that LDP is a feasible and safe procedure in patients with benign or low grade malignancies. Decreased blood loss and morbidity, early recovery and shorter hospital stay may be the main advantages. Several concerns still exist for laparoscopic pancreatic adenocarcinoma excision. The individual surgeon determines the technical conduction of LDP, with or without spleen preservation; currently robotic pancreatic surgery has gained diffusion. Additional researches are necessary to determine the best technique to improve the procedure results. PMID:23082049

    2015-09-01

    Gynecomastia is defined as excess glandular growth of breast tissue in males. It is a noticeable physical difference that commonly affects males in adolescence and old age. While often transient in nature, gynecomastia persists indefinitely in 10% of cases. Much of the literature on gynecomastia has focused on etiology and management. Little research has been done regarding the impact of gynecomastia on one's mental health and quality of life; however, some studies have suggested various psychosocial and psychological consequences related to gynecomastia. These consequences include but are not limited to depression, anxiety, disordered eating, body dissatisfaction, and reduced self-esteem. The aims of this paper are to review the current gynecomastia literature, bring awareness to an understudied but troubled population, and discuss directions for future work, including offering extant models of body image to guide researchers.

    2011-01-01

    Evidence in the literature suggests job satisfaction can make a difference in keeping qualified workers on the job, but little research has been conducted focusing specifically on allied health faculty. In order to attract and retain top quality faculty, colleges and universities should understand the variables impacting faculty satisfaction and develop a plan to enhance satisfaction. An integrative literature review (CINHAL, ERIC, Journal of Allied Health, Chronicle of Higher Education, Research in Higher Education, and current books on job satisfaction) of faculty job satisfaction and dissatisfaction produced a variety of publications presenting the key determinants of job satisfaction by allied health faculty in the United States. The purpose of the analysis was to examine the various factors that influence job satisfaction, especially by allied health faculty, in institutions of higher education in the U.S. The procedure used for this analysis consisted of reviewing allied health and higher education faculty studies to identify factors influencing job satisfaction, research questions, sample size reported, instruments used for measurement of job satisfaction, and job satisfaction results. While the theoretical models of allied health and higher education faculty job satisfaction exist separately in the literature, their remarkable similarities permit the prospect of a contemporary framework of the essential components of job satisfaction. Potential opportunities for continuing research on the personal and professional variables impacting job satisfaction of allied health faculty and similar disciplines are presented.

  16. Self-injury and externalizing pathology: a systematic literature review.

    2017-05-03

    During the last decade there is a growing scientific interest in nonsuicidal self-injury (NSSI). The aim of the current paper was to review systematically the literature with a special focus on the associations between self-injurious behaviours and externalizing psychopathology. An additional aim was to review terminology and measurements of self-injurious behaviour and the connection between self-injurious behaviours and suicide in the included publications. A systematic literature search was conducted on 31st December 2016 in five databases (PubMed, OVID Medline, OVID PsycINFO, Scopus, Web of Science) with two categories of search terms (1. nonsuicidal self-injury, non-suicidal self-injury, NSSI, self-injurious behaviour, SIB, deliberate self-harm, DSH, self-injury; 2. externalizing disorder, attention deficit hyperactivity disorder, ADHD, conduct disorder, CD, oppositional defiant disorder, OD, ODD). Finally 35 papers were included. Eleven different terms were found for describing self-injurious behaviours and 20 methods for measuring it. NSSI has the clearest definition. All the examined externalizing psychopathologies had strong associations with self-injurious behaviours according to: higher prevalence rates in externalizing groups than in control groups, higher externalizing scores on the externalizing scales of questionnaires, higher symptom severity in self-injurious groups. Eight studies investigated the relationship between suicide and self-injurious behaviours and found high overlap between the two phenomena and similar risk factors. Based on the current findings the association between externalizing psychopathology and self-injurious behaviours has been proven by the scientific literature. Similarly to other reviews on self-injurious behaviours the confusion in terminology and methodology was noticed. NSSI is suggested for use as a distinct term. Further studies should investigate the role of comorbid conditions in NSSI, especially when internalizing

    Landslide susceptibility assessment, the subject of this systematic review, is aimed at understanding the spatial probability of slope failures under a set of geomorphological and environmental conditions. It is estimated that about 375 landslides that occur globally each year are fatal, with around 4600 people killed per year. Past studies have brought out the increasing cost of landslide damages which primarily can be attributed to human occupation and increased human activities in the vulnerable environments. Many scientists, to evaluate and reduce landslide risk, have made an effort to efficiently map landslide susceptibility using different statistical methods. In this paper, we do a critical and systematic landslide susceptibility literature review, in terms of the different statistical methods used. For each of a broad set of studies reviewed we note: (i) study geography region and areal extent, (ii) landslide types, (iii) inventory type and temporal period covered, (iv) mapping technique (v) thematic variables used (vi) statistical models, (vii) assessment of model skill, (viii) uncertainty assessment methods, (ix) validation methods. We then pulled out broad trends within our review of landslide susceptibility, particularly regarding the statistical methods. We found that the most common statistical methods used in the study of landslide susceptibility include logistic regression, artificial neural network, discriminant analysis and weight of evidence. Although most of the studies we reviewed assessed the model skill, very few assessed model uncertainty. In terms of geographic extent, the largest number of landslide susceptibility zonations were in Turkey, Korea, Spain, Italy and Malaysia. However, there are also many landslides and fatalities in other localities, particularly India, China, Philippines, Nepal and Indonesia, Guatemala, and Pakistan, where there are much fewer landslide susceptibility studies available in the peer-review literature.

    Neurogenic stuttering is a disorder of neurologic origin in the rhythm of speech during which the patient knows exactly what he wants to say but is unable to because of an involuntary prolongation, cessation or repetition of a sound. To assemble new insights regarding the epidemiology, pathophysiology, diagnosis, evaluation and treatment of neurogenic stuttering. A review of all PubMed and Scopus published articles between January 2000 and September 2016 was performed. Thirty-three publications were analyzed. Neurogenic stuttering is a rare entity whose epidemiological incidence is yet not fully established. It is correlated with several neurological diseases and with several possible localizations within the nervous system. Notwithstanding the recent advances in the understanding of the underlying mechanism, it is not yet possible to establish a single pathophysiological mechanism of neurogenic stuttering. The differential diagnosis is complex and requires the detailed knowledge of other language disorders. The treatment is currently based on specific speech language therapy strategies. Neurogenic stuttering is a complex disorder which is not fully understood. Additional studies might help to better explain the underlying pathophysiological mechanism and to open doors to novel therapeutic methods.

    2015-06-25

    The history of histology indicates that there have been significant changes in the techniques used for histological staining through chemical, molecular biology assays and immunological techniques, collectively referred to as histochemistry. Early histologists used the readily available chemicals to prepare tissues for microscopic studies; these laboratory chemicals were potassium dichromate, alcohol and the mercuric chloride to harden cellular tissues. Staining techniques used were carmine, silver nitrate, Giemsa, Trichrome Stains, Gram Stain and Hematoxylin among others. The purpose of this research was to assess past and current literature reviews, as well as case studies, with the aim of informing ways in which histological stains have been improved in the modern age. Results from the literature review has indicated that there has been an improvement in histopathology and histotechnology in stains used. There has been a rising need for efficient, accurate and less complex staining procedures. Many stain procedures are still in use today, and many others have been replaced with new immunostaining, molecular, non-culture and other advanced staining techniques. Some staining methods have been abandoned because the chemicals required have been medically proven to be toxic. The case studies indicated that in modern histology a combination of different stain techniques are used to enhance the effectiveness of the staining process. Currently, improved histological stains, have been modified and combined with other stains to improve their effectiveness.

    There is a diversity of human reliability analysis (HRA) methods available for use in assessing human performance within probabilistic risk assessments (PRA). Due to the significant differences in the methods, including the scope, approach, and underlying models, there is a need for an empirical comparison investigating the validity and reliability of the methods. To accomplish this empirical comparison, a benchmarking study comparing and evaluating HRA methods in assessing operator performance in simulator experiments is currently underway. In order to account for as many effects as possible in the construction of this benchmarking study, a literature review was conducted, reviewing past benchmarking studies in the areas of psychology and risk assessment. A number of lessons learned through these studies is presented in order to aid in the design of future HRA benchmarking endeavors.

    2017-08-01

    Systematic reviews aide the analysis and dissemination of evidence, using rigorous and transparent methods to generate empirically attained answers to focused research questions. Identifying all evidence relevant to the research questions is an essential component, and challenge, of systematic reviews. Gray literature, or evidence not published in commercial publications, can make important contributions to a systematic review. Gray literature can include academic papers, including theses and dissertations, research and committee reports, government reports, conference papers, and ongoing research, among others. It may provide data not found within commercially published literature, providing an important forum for disseminating studies with null or negative results that might not otherwise be disseminated. Gray literature may thusly reduce publication bias, increase reviews' comprehensiveness and timeliness, and foster a balanced picture of available evidence. Gray literature's diverse formats and audiences can present a significant challenge in a systematic search for evidence. However, the benefits of including gray literature may far outweigh the cost in time and resource needed to search for it, and it is important for it to be included in a systematic review or review of evidence. A carefully thought out gray literature search strategy may be an invaluable component of a systematic review. This narrative review provides guidance about the benefits of including gray literature in a systematic review, and sources for searching through gray literature. An illustrative example of a search for evidence within gray literature sources is presented to highlight the potential contributions of such a search to a systematic review. Benefits and challenges of gray literature search methods are discussed, and recommendations made. © 2017 Chinese Cochrane Center, West China Hospital of Sichuan University and John Wiley & Sons Australia, Ltd.

    Kõlves, Kairi; Barker, Emma; De Leo, Diego

    2015-01-01

    Allergies are among the most common chronic conditions. In addition to physical and social impacts, a number of studies have consistently linked allergies to poor psychological outcomes, including depression and anxiety. The aim of the present systematic literature review was to analyze the existing literature about the relationship between allergies and fatal and nonfatal suicidal behaviors. Data sources include articles retrieved from Scopus, PubMed, ProQuest, and Web of Knowledge. Search terms: "suicid* and (allerg* or hay fever or atop* or eczema or aeroallergen*)" in English-language peer-reviewed journals between 1990 and 2014. Original research articles that provide empiric evidence about the potential link between allergies and suicidal behaviors. The initial search identified a total of 769 articles with 17 original research articles that present empiric evidence. Nine articles analyzed the relationship between allergies and fatal suicidal behavior, and nine analyzed nonfatal suicidal behaviors (one article included both). There currently is little research into the relationship between allergies and suicidal behavior. The review was restricted to English-language articles published within the chosen time period; other limitations included the small number of articles that involve suicide mortality, and the fact that the majority of articles originated from the United States and Scandinavia. Analysis of the results indicates a link between allergies and suicidality, particularly suicide mortality; however, results for nonfatal suicidal behaviors are mixed. It is important that further research by using more rigorous study designs be carried out to lend strength to these findings.

    Gould, R.; McFadden, S.L.; Hughes, C.M.

    2017-01-01

    Objectives: It is believed that children are more sensitive to ionising radiation than adults. This work reviewed the reported radiation dose estimates for paediatric cardiac catheterisation. A systematic literature review was performed by searching healthcare databases for studies reporting radiation dose using predetermined key words relating to children having cardiac catheterisation. The quality of publications was assessed using relevant Critical Appraisal Skills Programme questions and their reported radiation exposures were evaluated. Key findings: It is only in recent years that larger cohort observations have been undertaken. Although radiation dose from paediatric cardiac catheterisation has decreased in recent years, the literature indicated that it remains varied and potentially substantial. Conclusion: Standardisation of weight categories and procedure types such as those recommended by the PiDRL project could help compare current and future radiation dose estimates. - Highlights: • 31 articles reporting radiation dose from paediatric cardiac catheterisation were reviewed. • In recent years, larger cohorts (>1000) have been reported. • Radiation dose to children has been lowered in the last decade but remains varied. • Future dosimetry should be consistent for weight categories and procedure types.

    Full Text Available The purpose of this paper is to present the state of the art of research in Information Technology (IT in Change Management (CM. Initial studies indicate that investments into CM in IT often do not add the predictable value, neither to the CM division himself nor to the association supported by the CM section. A basis for further study into this complex and inter disciplinary area is therefore needed. This literature review will contribute to this basis. Based on a Systematic Literature Review (SLR method, journal articles, with a focus on CM in IT were found. Relevant articles were organized in categories according to focus on Technology, IT layer, CM process and theory, research method applied and type of findings. Finally research gaps were identified. There seems to be a general belief in technology combinations as a way to speed up the rather slow IT diffusion process in CM. It is documented that current research into CM in IT has an unbalanced focus on few specific technologies, IT layers and CM processes, and that further research should focus more on the IT implementation process and use. Knowledge from application and use could be fed back into (and strengthen conceptualization and progress, thereby adding more value to CM. Only the search engine Scopus is used. This is the first review paper focusing on CM in general in IT, giving an overview of the area and delivering a basis for further research.

    2017-01-01

    Adults perpetrate the majority of animal abuse incidents yet clinicians are left with very little evidence base to advance/enhance their practice. The purpose of this systematic review is to synthesize and evaluate the current literature on adult-perpetrated animal abuse and to identify the etiological factors related to this type of offending. Twenty-three studies met the specific inclusion criteria but most importantly, they examined the characteristics of adult perpetrators of animal abuse. The findings from this review were demarcated by sample type: (1) Participants were the perpetrators of the animal abuse or held offense-supportive attitudes and (2) participants were victims of intimate partner violence reporting incidents of animal abuse perpetrated by their partner. From the perpetrator perspective, there were key developmental (i.e., maladaptive parenting strategies), behavioral (such as varied offending behaviors), and psychological (e.g., callousness, empathy deficits) factors highlighted in the literature. Finally, in the context of intimate partner violence, findings indicated that perpetrators abuse animals to control, coerce, intimidate, and/or manipulate their victims (this effect is moderated by the victims' emotional attachment to their pet). This review inherently underlines treatment targets that could achieve greater clinical gains, but we also conclude that more empirical and theoretical work is needed in order to set an agenda that prioritizes future research and effective practice.

    2017-11-01

    Background: The current version of the Lives Saved Tool (LiST) maternal and child health impact modeling software does not include an effect of malaria on stunting. Objective: This literature review was undertaken to determine whether such a causal link should be included in the LiST model. Methods: The PubMed, Embase, and Scopus databases were searched by using broad search terms. The searches returned a total of 4281 documents. Twelve studies from among the retrieved documents were included in the review according to the inclusion and exclusion criteria. Results: There was mixed evidence for an effect of malaria on stunting among longitudinal observational studies, and none of the randomized controlled trials of malaria interventions found an effect of the interventions on stunting. Conclusions: There is insufficient evidence to include malaria as a determinant of stunting or an effect of malaria interventions on stunting in the LiST model. The paucity and heterogeneity of the available literature were a major limitation. In addition, the studies included in the review consistently fulfilled their ethical responsibility to treat children under observation for malaria, which may have interfered with the natural history of the disease and prevented any observable effect on stunting or linear growth. © 2017 American Society for Nutrition.

    Engagement at work has emerged as a potentially important employee performance and organizational management topic, however, the definition and measurement of engagement at work, and more specifically, nurse engagement, is poorly understood. The objective of this paper is to examine the current state of knowledge about engagement at work through a review of the literature. This review highlights the four lines of engagement research and focuses on the determinants and consequences of engagement at work. Methodological issues, as identified in the current research, and recommendations for future nurse-based engagement research are provided. A systematic review of the business, organizational psychology, and health sciences and health administration literature about engagement at work (1990-2007) was performed. The electronic databases for Health Sciences and Health Administration (CINAHL, MEDLINE), Business (ABI INFORM), and Psychology (PsycINFO) were systematically searched. Due to the limited amount of research that has examined engagement among the nursing workforce, published research that included varying employee types were included in this review. The selection criteria for this review include those studies that were: (1) written in English and (2) examined engagement at work in employee populations of any type within any work setting. The literature review identified four distinct lines of research that has focused on engagement within the employee work role. Of the 32 engagement-based articles referenced in this paper, a sample of 20 studies report on the examination of antecedents and/or consequences of engagement at work among varying employee types and work settings. Key findings suggest organizational factors versus individual contributors significantly impact engagement at work. A common implication in this body of research was that of the performance-based impact. The study of nurses' work engagement and its relationship to nurses' organizational

    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.

    Public safety and acceptance is extremely important for the nuclear power renaissance to get started. The Advanced Burner Reactor and other potential designs utilize liquid sodium as a primary coolant which provides distinct challenges to the nuclear power industry. Fire is a dominant contributor to total nuclear plant risk events for current generation nuclear power plants. Utilizing past experience to develop suitable safety systems and procedures will minimize the chance of sodium leaks and the associated consequences in the next generation. An advanced understanding of metal fire behavior in regards to the new designs will benefit both science and industry. This report presents an extensive literature review that captures past experiences, new advanced reactor designs, and the current state-of-knowledge related to liquid sodium combustion behavior

    Any human activity generates noise. It is considered as a risk factor for people's health. The present review of literature has assessed the impact of noise on mental health; it is summarized into four points: objective, methods, results and conclusion. The main objective of this study is to expose the actual knowledge state of noise effects on mental health after overview and critical analysis of literature to identify the acquired and shortcomings, to reflect on research direction in terms of noise pollution in the future. The literature review was conducted based on: research of keys words in articles published, research of the number of quotations of articles in Journal Citation Reports (JCR), published in web of science, research of impact factor of journals. One hundred articles were selected, after analyzing contents, items were classified into: fundamental studies (25%), experimental studies (50%), and epidemiological studies (25%). The fundamental studies have verified the hypothesis according to which noise generates stress. Researchers have dosed hormones of stress in plasma, urine and saliva in individuals exposed to noise of different decibels. The results found were unanimous: The rates of stress hormones found, were significantly high in three liquids. This means that noise causes stress. For experimental studies, researchers have experienced the role of noise on memory, attention and performance. Human subjects were exposed to different decibels to assess level of disruption to their memory, attention, and performance. The results revealed that noise disturbs memory, distracts attention and decreases performance. Experimental studies are the most abundant and constitute 50% of the current literature review.The epidemiological studies have evaluated the intellectual performance of students in schools located in noisy environments and residents in areas surrounding airports, railways and highways. RESULTS have revealed that students in schools located

  10. Mapping the organizational culture research in nursing: a literature review.

    Scott-Findlay, Shannon; Estabrooks, Carole A

    2006-12-01

    This paper reports a critical review of nursing organizational culture research studies with the objectives of: (1) reviewing theoretical and methodological characteristics of the studies and (2) drawing inferences specific to the state of knowledge in this field. Organizational culture is regarded as significant in influencing research use in clinical practice yet it is not understood how culture shapes practitioners' behaviours. Only one review of this empirical literature in nursing has been completed. Using selected computerized databases, published nursing research studies in English that examine organizational culture were accessed. Organizational culture studies were categorized using Hatch's three perspectives on organizational culture: (1) modern, (2) symbolic-interpretive and (3) postmodern. The review was conducted in 2005. Twenty-nine studies were in the final data set. Results pointed to variations in cultural definitions and incorporation of organizational sciences theory. In classifying the studies, modern perspectives dominated (n = 22), symbolic-interpretive approaches were an emerging group (n = 6) and one study was unclassifiable. Our results expand current cultural instrument reviews by pinpointing tools that have been previously overlooked and by identifying ongoing theoretical and methodological challenges for researchers. An exclusive reliance on modernistic approaches in organizational culture research cannot yield a complete understanding of the phenomenon. Rather, the field could benefit from a variety of cultural approaches. In a similar vein, researchers need to be mindful of the terminology and the unit of analysis they use in their research, as these are the two largest research challenges.

The purpose of our review was to identify evidence-based clinical research for the evaluation and management of preexisting chronic pain in pregnancy, chronic pain associated with pregnancy, and chronic pain in relation to mode of delivery. Methods: A literature search was undertaken using the search engines PubMed, CINAHL, EBSCOhost, and Web of Science. Search terms used included “chronic pain” AND “pregnant OR pregnancy” OR “pregnancy complications” from inception through August 2016. Results: The basis of this review was the 144 articles that met inclusion criteria for this review. Based on our review of the current literature, we recommend 7 guidelines for chronic pain management during and after pregnancy: 1 complete history and physical examination; 2 monitor patients for alcohol, nicotine, and substance use; 3 collaborate with patient to set treatment goals; 4 develop a management plan; 5 for opioids, use lowest effective dose; 6 formulate a pain management plan for labor and delivery; and 7 discuss reproductive health with women with chronic pain. Conclusion: The management of chronic pain associated with pregnancy is understudied. Obstetrical providers primarily manage chronic pain during pregnancy. Some general guidelines are provided for those health care providers until more information is available. Keywords: chronic pain, pregnancy, pregnancy complications, chronic pain in pregnancy

    Borderline ovarian tumours are semimalignant tumours occurring unilaterally or bilaterally with a peak incidence among women of reproductive age. Since the affected women often wish to preserve fertility, particular precautions must be taken when counselling the patient and obtaining consent prior to planning an individual treatment. Options for preserving fertility include an organ-sparing surgical procedure and cryopreservation of oocytes and/or ovarian tissue. In this article, we report on a 25-year-old patient with a bilateral seromucinous borderline tumour who desired all fertility-preserving options. In order to perform the procedure without delay, we opted to perform luteal phase stimulation prior to oocyte retrieval. We conclude by discussing the current literature on the state of fertility preservation in the treatment of borderline ovarian tumours.

The review will also report on published outcomes and future research needs of embedded librarian programs.Methods – A search of current literature was conducted and summarized searching PubMed, CINAHL, Library, Information Science & Technology Abstracts (EBSCO, Academic Search Complete, and ERIC (EBSCO through August 23, 2012. Articles wereselected for inclusion in the review if they reported research findings related to embedded librarianship, if they provided unique case reports about embedded librarian programs, or if they provided substantive editorial comments on the topic. Relevant study findings were assessed for quality and presented in tabular and narrative form.Results – Currently, there is disparity in how embedded librarianship is being definedand used in common practice, ranging from embedding an online component into asingle course to full physical and cultural integration into an academic college orbusiness unit of an organization. Activities of embedded librarians include creatingcourse integrated instruction modules for either face-to-face or online courses, providingin depth research assistance to students or faculty, and co-locating within colleges orcustomer units via office hours for a few hours to all hours per week. Several case reports exist in the recent literature. Few high quality research studies reporting outcomes of librarians or library programs labeled as embedded exist at this point. Some evidence suggests that embedded librarians are effective with regards to student learning of information literacy objectives. Surveys suggest that both students and faculty appreciate embedded librarian services.Conclusion – Most published accounts discuss librarians embedding content and ready access to services in an online course management system.

    The objective of this literature review was to summarise current research regarding how consumers seek health-related information from social media. Primarily, we hope to reveal characteristics of existing studies investigating the health topics that consumers have discussed in social media, ascertaining the roles social media have played in consumers' information-seeking processes and discussing the potential benefits and concerns of accessing consumer health information in social media. The Web of Science Core Collection database was searched for existing literature on consumer health information seeking in social media. The search returned 214 articles, of which 21 met the eligibility criteria following review of full-text documents. Between 2011 and 2016, twenty-one studies published explored various topics related to consumer information seeking in social media. These ranged from online discussions on specific diseases (e.g. diabetes) to public health concerns (e.g. pesticide residues). Consumers' information needs vary depending on the health issues of interest. Benefits of health seeking on social media, in addition to filling a need for health information, include the social and emotional support health consumers gain from peer-to-peer interactions. These benefits, however, are tempered by concerns of information quality and authority and lead to decreased consumer engagement. © 2017 Health Libraries Group.

    A series of human factors evaluations were undertaken to better understand the contributing factors to human error in the teletherapy environment. Teletherapy is a multidisciplinary methodology for treating cancerous tissue through selective exposure to an external beam of ionizing radiation. A team of human factors specialists, assisted by a panel of radiation oncologists, medical physicists, and radiation therapists, conducted site visits to radiation oncology departments at community hospitals, university centers, and free-standing clinics. A function and task analysis was performed initially to guide subsequent evaluations in the areas of workplace environment, system-user interfaces, procedures, training, and organizational practices. To further acquire an in-depth and up-to-date understanding of the practice of teletherapy in support of these evaluations, a systematic literature review was conducted. Factors that have a potential impact on the accuracy of treatment delivery were of primary concern. The present volume is the literature review. The volume starts with an overview of the multiphased nature of teletherapy, and then examines the requirement for precision, the increasing role of quality assurance, current conceptualizations of human error, and the role of system factors such as the workplace environment, user-system interfaces, procedures, training, and organizational practices.

  7. Risk of psychosis in refugees: a literature review.

    Dapunt, J; Kluge, U; Heinz, A

    2017-06-13

    Conflicts and precarious living conditions resulted in the arrival of large numbers of refugees in Europe and especially in Germany. Evidence suggests that immigrant populations are at elevated risk of psychotic disorders. Considering the traumatic pre- and post-migratory adversities refugees may have encountered, people granted refugee status may even be more susceptible to psychosis than non-refugee migrants. The aim of this literature review is to summarise and interpret recent research on the incidence or prevalence of psychotic disorders in refugees, additionally focusing on the aspects of gender and Middle Eastern provenance. A systematic search in PubMed was performed in the time from 20 to 28 May 2016. Relevant literature was limited to articles describing cohort studies conducted in Western industrialised countries. Articles published between 1 June 2006 and 28 May 2016 were analysed. Content relating to psychotic disorders in refugees was reviewed and summarised. The selected studies showed an increased risk of psychotic disorders in refugees compared with both the indigenous population and non-refugee. migrants. The elevated risk was more pronounced in refugee men. A particularly high risk in refugees of Middle Eastern origin could not be inferred. The higher susceptibility to psychotic disorders in refugees emphasises the need for the development and implementation of adequate prevention strategies. Clinicians and people working in a refugee setting should be aware of early signs and symptoms of psychosis. Further research is required to evaluate post-migratory experiences and investigate the population of refugees affected by the current humanitarian crisis.

  8. Ethics education for pediatric residents: a review of the literature

    Directory of Open Access Journals (Sweden)

    Raywat Deonandan

    2015-04-01

    Full Text Available Background: Ethics education and research on medical residents is needed because, unlike medical students or experienced doctors, medical residents have to perform multiple roles simultaneously – student, teacher and clinician – thus exposing them to unique ethical stressors.  In this paper we reviewed the literature concerning ethics education in postgraduate pediatrics training programs.  Our goal was not to simply describe educational strategies and programs, but also to explore measurements and experiences of current practices to address gaps in ethics education during residency. Method: We conducted a structured literature review to explore the extent of ethics education in pediatric residency programs.  Results:  Twelve relevant studies were found.  The studies suggest that existing training regimens are insufficient to meet the real life ethical challenges experienced in actual practice, particularly with respect to palliative care and the commission of clinical errors.  Conclusions: The increasing diversity of culture and beliefs in the clinical workplace is also serving to complicate educational needs. An interdisciplinary approach, spread over the entirety of a physician’s training, is a proposed solution worthy of more attention.

Exclusion criteria were: articles in duplicate; no available summaries; not empirical; not assessing any component of body image; the sample did not consider the target age of this research (0 to 12 years old) and/or considered clinical populations; besides articles not fully available. 7,681 references were identified, and, after the exclusion criteria were implemented, 33 studies were analysed. Results showed that the perceptual and attitudinal dimensions focusing on body dissatisfaction were explored, mainly evaluated by silhouette scales. Intervention programs were developed internationally to prevent negative body image in children. The studies included in this review evaluated specific aspects of body image in children, especially body perception and body dissatisfaction. The creation of specific tools for children to evaluate body image is recommended to promote the psychosocial well being of individuals throughout human development.

    Personal assistance services (PAS) can be valuable adjuncts to the complement of accommodations that support workers with disabilities. This literature review explored the professional literature on the use of PAS in the workplace. Bibliographic sources were used to locate relevant research studies on the use of PAS in the workplace. The studies in this review used both qualitative and quantitative methods to identify current definitions of work-related and personal care-related PAS, agency-directed versus consumer-directed PAS, long-term and short-term funding issues, development of PAS policy, and barriers to successful implementation of PAS. The studies uncovered issues related to (a) recruiting, training, and retaining personal assistants, (b) employer concerns, (c) costs and benefits of workplace PAS, (d) wages and incentives for personal assistants, and (e) sources for financing PAS as a workplace accommodation. The findings reveal the value and benefits of effective PAS on the job. PAS can lead to successful employment of people with disabilities when other accommodations cannot provide adequate workplace support. Additionally, the evolution of workplace PAS is dependent on development of realistic PAS policy and funding options. Published by Elsevier Inc.

    The group of passive prostheses consists of prosthetic hands and prosthetic tools. These can either be static or adjustable. Limited research and development on passive prostheses has been performed although many people use these prosthesis types. Although some publications describe passive prostheses, no recent review of the peer-reviewed literature on passive prostheses is available. Review the peer-reviewed literature on passive prostheses for replacement of the hand. Literature review. Four electronic databases were searched using a Boolean combination of relevant keywords. English-language articles relevant to the objective were selected. In all, 38 papers were included in the review. Publications on passive prosthetic hands describe their users, usage, functionality, and problems in activities of daily living. Publications on prosthetic tools mostly focus on sport, recreation, and vehicle driving. Passive hand prostheses receive little attention in prosthetic research and literature. Yet one out of three people with a limb deficiency uses this type of prosthesis. Literature indicates that passive prostheses can be improved on pulling and grasping functions. In the literature, ambiguous names are used for different types of passive prostheses. This causes confusion. We present a new and clear classification of passive prostheses. Clinical relevance This review provides information on the users of passive prosthetic hands and tools, their usage and the functionality. Passive prostheses receive very little attention and low appreciation in literature. Passive prosthetic hands and tools show to be useful to many unilateral amputees and should receive more attention and higher acceptance.

    2018-04-01

    The National Infrastructure Simulations and Analysis Center (NISAC) conducted a literature review on modeling cyber networks and evaluating cyber risks. The literature review explores where modeling is used in the cyber regime and ways that consequence and risk are evaluated. The relevant literature clusters in three different spaces: network security, cyber-physical, and mission assurance. In all approaches, some form of modeling is utilized at varying levels of detail, while the ability to understand consequence varies, as do interpretations of risk. This document summarizes the different literature viewpoints and explores their applicability to securing enterprise networks.

    Full Text Available The current generation of nursing students in Higher Education, born in the 1980’s and early 1990’s, are referred to as millennials. All the terms given to this cohort, such as “digital natives” or “net generation” , are being used to highlight the impact that new technologies have to their lives. Regardless how you call them, digital natives are a puzzle generation we do not know much about it, apart from the fact that they have already entered the tertiary nursing education. Numerous surveys indicate that emerging technologies constitute a defining feature in the lives of current students, estimating that there is a fundamental shift in the way young people communicate, socialize and learn. Today£s students are characterized as digital literate with distinct traits which influence their learning preferences. New pedagogical methods, such as active and experiential learning, cooperative activities, instant feedback and technology integration, come forward. The purpose of this literature review is to outline nursing students’ key traits and learning profile, as presented in the existing literature.

    Minimally invasive surgery for liver resections has a defined role and represents an accepted alternative to open techniques for selected cases. Robotic technology can overcome some of the disadvantages of the laparoscopic technique, mainly in the most complex cases. Precise dissection and microsuturing is possible, even in narrow operative fields, allowing for a better dissection of the hepatic hilum, fine lymphadenectomy, and biliary reconstruction even with small bile ducts and easier bleeding control. This technique has the potential to allow for a greater number of major resections and difficult segmentectomies to be performed in a minimally invasive fashion. The implementation of near-infrared fluorescence with indocyanine green (ICG) also allows for a more accurate recognition of vascular and biliary anatomy. The perspectives of this kind of virtually implemented imaging are very promising and may be reflected in better outcomes. The overall data present in current literature suggests that robotic liver resections are at least comparable to both open and laparoscopic surgery in terms of perioperative and postoperative outcomes. This article provides technical details of robotic liver resections and a review of the current literature. PMID:27500143

    Simulation-based learning is an educational intervention which creates an environment that is conducive to experiential learning. Despite the prevalence of research on the influence of simulation on nursing education, there is a dearth of literature on the effectiveness of simulation-based learning. This systematic review examines literature on simulation outcomes in nursing education from the years 2000-2010. The electronic databases reviewed for the systematic review of the literature included: CINAHL Plus, Medline, Health Source: Nursing/Academic Education, Google Scholar, and Digital Dissertations and Theses through ProQuest. The MeSH search terms included "simulation outcomes measurement" and "nursing education". Seventeen studies were included in the review of the literature. The literature was categorized into three themes; internal outcomes, external outcomes, and clinical evaluation. The available literature on simulation and nursing education provides evidence that that simulation is useful in creating a learning environment which contributes to knowledge, skills, safety, and confidence. This systematic review of the literature revealed a gap in the literature pertaining to the transfer of these outcomes to the clinical setting, and lays a foundation for further research on outcomes specific to simulation and nursing education.

    Effective mentoring is an invaluable element in the development of next generation of neurosurgeons. A mentor helps to develop professional core values, technical and non-technical skills, attitudes and disposition required to be qualified and competent neurosurgeon. Giving the invaluable significance of mentoring in neurosurgery, we undertook this literature review to identify mentoring models evaluating its success and relative benefit. Literature search identified using MeSH word 'mentor', mentoring, mentorship, mentoring model, neurosurgery' in MEDLINE, EMBASE and Scopus databases from 1990 to 2016. Literature reviewed to identify status of mentoring in neurosurgery, potential barriers, pitfalls and future framework for mentoring in neurosurgery. Additional articles identified through manual search of reference lists. A total of 247 studies were obtained from electronic databases, after removing duplicates, abstracts, letters to the editor and non-neurosurgery papers. Sixteen full text articles retrieved out of which five met the inclusion criteria. Generally, there is paucity of articles regarding mentoring in neurosurgery, all included papers were written in English Language, all of them described mentoring model used including simulation, distance, collaborative, facilitative tele-mentoring and peer mentoring. Mentoring in Neurosurgery is an important aspect of personal and professional development of neurosurgical trainees, currently there is decline in traditional apprenticeship due to increase demand for modern use of specialised technology, simulation and tele-medicine in neurosurgery practice. Effective and efficient mentoring will be an interplay of six mentoring models (collaborative, facilitative, distance, simulation, tele mentoring and peer mentoring) identified.

    2008-06-19

    The evolving concepts of pervasive computing, ubiquitous computing and ambient intelligence are increasingly influencing health care and medicine. Summarizing published research, this literature review provides an overview of recent developments and implementations of pervasive computing systems in health care. It also highlights some of the experiences reported in deployment processes. There is no clear definition of pervasive computing in the current literature. Thus specific inclusion criteria for selecting articles about relevant systems were developed. Searches were conducted in four scientific databases alongside manual journal searches for the period of 2002 to 2006. Articles included present prototypes, case studies and pilot studies, clinical trials and systems that are already in routine use. The searches identified 69 articles describing 67 different systems. In a quantitative analysis, these systems were categorized into project status, health care settings, user groups, improvement aims, and systems features (i.e., component types, data gathering, data transmission, systems functions). The focus is on the types of systems implemented, their frequency of occurrence and their characteristics. Qualitative analyses were performed of deployment issues, such as organizational and personnel issues, privacy and security issues, and financial issues. This paper provides a comprehensive access to the literature of the emerging field by addressing specific topics of application settings, systems features, and deployment experiences. Both an overview and an analysis of the literature on a broad and heterogeneous range of systems are provided. Most systems are described in their prototype stages. Deployment issues, such as implications on organization or personnel, privacy concerns, or financial issues are mentioned rarely, though their solution is regarded as decisive in transferring promising systems to a stage of regular operation. There is a need for further

    Significant attention has been directed toward the immediate and long-term effects of sport-related concussions on athletes participating in contact sports, particularly football. The highest level of football, the National Football League (NFL), has received significant attention and criticism regarding player management and safety after mild traumatic brain injury (mTBI). Several review articles have reported data related to concussion in the NFL, but a succinct review and synthesis of data regarding NFL concussions is currently lacking. To (1) review systematically the published data regarding concussion in the NFL and assess limitations of the studies, (2) elucidate areas where further research is needed, and (3) identify methods to improve future investigations of concussion in the NFL. Systematic review of literature. English-language titles and abstracts published between 1900 and September 2014 were searched systematically across electronic databases, and a review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Peer-reviewed journal articles were included if they contained NFL concussion data with or without additional associated long-term effects. Reviews, editorials, letters to the editor, and comments were not included. Of the 344 records screened for review, 88 articles were assessed for eligibility. There were 31 studies that met the inclusion criteria and formed the basis of the evidence synthesis. Included in the current review were 8 case-control studies (Oxford Centre for Evidence-Based Medicine evidence level 3b), 6 descriptive epidemiological studies (level 4), 6 cross-sectional studies (level 4), 6 cohort studies (level 2b), and 5 case series (level 4). The study of concussions in the NFL has been limited by lack of recent empirical data, reliance on self-reported concussion history, and ascertainment bias of brains donated for autopsy studies.

    Westwood, Heather; Tchanturia, Kate

    2017-07-01

    There is growing interest in the relationship between anorexia nervosa (AN) and autism spectrum disorder (ASD). This review aimed to synthesise the most recent research on this topic to identify gaps in current knowledge, directions for future research and reflect on implications for treatment. Eight studies assessing the presence of ASD in AN were identified in the literature along with three studies examining the impact of symptoms of ASD on treatment outcome. Research with young people and using parental-report measures suggest lower rates of co-morbidity than previous adult studies. The wide range of diagnostic tools, methodologies and populations studied make it difficult to determine the prevalence of ASD in AN. Despite this, studies consistently report over-representation of symptoms of ASD in AN. Co-morbid AN and ASD may require more intensive treatment or specifically tailored interventions. Future longitudinal research and female-specific diagnostic tools would help elucidate the relationship between these two disorders.

    Agnieszka Laura Sabiniewicz

    2017-07-01

    Full Text Available The paper contains a review of the literature concerning memory abilities and human senses performance under different environmental circumstances. A number of studies indicated that environment has a significant impact on human senses functioning. It can affect it in a mechanical way, by a chronic exposure to potentially harmful substances or processes in different work environments. Also, some cognitive abilities that have evolved to perform evolutionary essential functions lost their importance because of the change of environment impact. Moreover, training can be a source of improvement of both human senses and cognitive abilities, as well. That might suggest that, while using, under different environmental circumstances different cognitive abilities develop. We take into a particular consideration human memory and its role, show current studies in this field and suggest new research directions.

    Juvenile recurrent parotitis (JRP) is the second most frequent salivary gland disease in childhood, defined as a recurrent non-suppurative and non-obstructive parotid inflammation. The recurring attacks actually represent the most dramatic and serious aspect of this pathology, since they significantly influence the quality of life, and there are no recognized therapies to avoid them. In recent years, there are reports of many international experiences related to the management of JRP by sialendoscopy. In this context, several authors have stressed the striking role of sialendoscopy in the prevention of JRP attacks. The objective of the current review is to overview the existing literature with particular regards to diagnostic and therapeutic outcomes after the application of sialendoscopy in patients suffering from JRP.

    Social media may offer support to individuals who are navigating the complex and challenging experience of cancer. A growing body of literature has been published over the last decade exploring the ways cancer survivors utilize social media. This study aims to provide a systematic synthesis of the current literature in order to inform cancer health communication practice and cancer survivorship research. Using PRISMA guidelines, four electronic databases were searched to retrieve publications on breast cancer and social media published between 2005 and 2015. The final sample included 98 publications (13 commentaries and reviews, 47 descriptive studies, and 38 intervention studies). Intervention studies were assessed for key features and outcome measures. Studies utilizing content analysis were further evaluated qualitatively. Online support groups were the most commonly studied platform, followed by interactive message boards and web forums. Limited research focuses on non-Caucasian populations. Psychosocial well-being was the most commonly measured outcome of interest. While social media engagement was assessed, few standardized measures were identified. Content analyses of social media interactions were prevalent, though few articles linked content to health outcomes. The current literature highlights the impact and potential utility of social media for breast cancer survivors. Future studies should consider connecting social media engagement and content to psychosocial, behavioral, and physical health outcomes. Online groups and communities may improve the well-being of breast cancer survivors by providing opportunities to engage with wider social networks, connect with others navigating similar cancer experiences, and obtain cancer-related information. Researchers should consider the potential role of social media in addressing the unmet needs of breast cancer survivors, and particularly the implications for clinical and public health practice.

    Context 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. Objective This study aims to identify specific challenges, proposed solutions, and unsolved problems faced when testing scientific software. Method We conducted a systematic literature survey to identify and analyze relevant literature. We identified 62 studies that provided relevant information about testing scientific software. Results 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. Conclusions 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. PMID:25125798
