Topical local anaesthetics provide effective analgesia for patients undergoing numerous superficial procedures, including repair of dermal lacerations. The need for cocaine in topical anaesthetic formulations has been questioned because of concern about adverse effects, thus novel preparations of cocaine-free anaesthetics have been developed. This review was originally published in 2011 and has been updated in 2017. To assess whether benefits of non-invasive topical anaesthetic application occur at the expense of decreased analgesic efficacy. To compare the efficacy of various single-component or multi-component topical anaesthetic agents for repair of dermal lacerations. To determine the clinical necessity for topical application of the ester anaesthetic, cocaine. For this updated review, we searched the following databases: Cochrane Central Register of Controlled Trials (CENTRAL; 2016, Issue 11), Cumulative Index to Nursing and Allied Health Literature (CINAHL; 2010 to December 2016), Embase (2010 to December 2016) and MEDLINE (2010 to December 2016). We did not limit this search by language or format of publication. We contacted manufacturers, international scientific societies and researchers in the field. Weemailed selected journalsand reviewed meta-registers of ongoing trials. For the previous version of this review, we searched these databases to November 2010. We included randomized controlled trials (RCTs) that evaluated the efficacy and safety of topical anaesthetics for repair of dermal laceration in adult and paediatric participants. Two review authors independently assessed trial quality and extracted data. We contacted study authors for additional information when needed. We collected adverse event information from trial reports. We assessed methodological risk of bias for each included study and employed the GRADE approach to assess the overall quality of the evidence. The present updated review included 25 RCTs involving 3278 participants. The small number of trials in each comparison group and the heterogeneity of outcome measures precluded quantitative analysis of data for all but one outcome: pain intensity. In two pooled studies, the mean self-reported visual analogue scale (VAS; 0 to 100 mm) score for topical prilocaine-phenylephrine (PP) was higher than the mean self-reported VAS (0 to 100 mm) score for topical tetracaine-epinephrine-cocaine (TAC) by 5.59 points (95% confidence interval (CI) 2.16 to 13.35). Most trials that compared infiltrated and topical anaesthetics were at high risk of bias, which is likely to have affected their results. Researchers found that several cocaine-free topical anaesthetics provided effective analgesic efficacy. However, data regarding the efficacy of each topical agent are based mostly on single comparisons in trials with unclear or high risk of bias. Mild, self-limited erythematous skin induration occurred in one of 1042 participants who had undergone application of TAC. Investigators reported no serious complications among any of the participants treated with cocaine-based or cocaine-free topical anaesthetics. The overall quality of the evidence according to the GRADE system is low owing to limitations in design and implementation, imprecision of results and high probability of publication bias (selective reporting of data). Additional well-designed RCTs with low risk of bias are necessary before definitive conclusions can be reached. We have found two new studies published since the last version of this review was prepared. We have added these studies to those previously included and have conducted an updated analysis, which resulted in the same review conclusions as were presented previously.Mostly descriptive analysis indicates that topical anaesthetics may offer an efficacious, non-invasive means of providing analgesia before suturing of dermal lacerations. Use of cocaine-based topical anaesthetics might be hard to justify, given the availability of other effective topical anaesthetics without cocaine. However, the overall quality of the evidence according to the GRADE system is low owing to limitations in design and implementation, imprecision of results and high probability of publication bias (selective reporting of data). Additional well-designed RCTs with low risk of bias are necessary before definitive conclusions can be reached.

Patient safety in the care of mentally ill people in Switzerland: Action plan 2016

PubMed

Richard, Aline; Mascherek, Anna C; Schwappach, David L B

2017-01-01

Background: Patient safety in mental healthcare has not attracted great attention yet, although the burden and the prevalence of mental diseases are high. The risk of errors with potential for harm of patients, such as aggression against self and others or non-drug treatment errors is particularly high in this vulnerable group. Aim: To develop priority topics and strategies for action to foster patient safety in mental healthcare. Method: The Swiss patient safety foundation together with experts conducted round table discussions and a Delphi questionnaire to define topics along the treatment pathway, and to prioritise these topics. Finally, fields of action were developed. Results: An action plan was developed including the definition and prioritization of 9 topics where errors may occur. A global rating task revealed errors concerning diagnostics and structural errors as most important. This led to the development of 4 fields of action (awareness raising, research, implementation, and education and training) including practice-oriented potential starting points to enhance patient safety. Conclusions: The action plan highlights issues of high concern for patient safety in mental healthcare. It serves as a starting point for the development of strategies for action as well as of concrete activities.

Many medications are available for treatment of pediculosis capitis including ivermectin. Our aim is to compare the efficacy and safety of topical versus oral ivermectin in treatment of pediculosis capitis. Sixty-two patients with proved head lice infestation were included and divided into group I (31 patients; received single topical application of 1% ivermectin) and group II (31 patients; received single dose of oral ivermectin). Treatment was repeated after 1 week for nonresponders. At 1 week after treatment, the eradication rates and improvement of pruritus were significantly higher among patients who received topical than oral ivermectin. When a second treatment, topical or oral, was given to nonresponders, the cure rates of infestation and pruritus was 100% and 97% among patients treated with topical and oral ivermectin, respectively with no significant difference between the two groups. This study suggests that both topical and oral ivermectin demonstrate high efficacy and tolerability in treatment of pediculosis capitis. However, a single treatment with topical ivermectin provides significantly higher cure of infestation and faster relief of pruritus than oral ivermectin. In addition, whether topical or oral ivermectin is used to treat head lice, a second dose is required in some cases to ensure complete eradication. © 2014 Wiley Periodicals, Inc.

Definition and configuration of clinical content in an enterprise-wide electronic health record (EHR) implementation is highly complex. Sharing of data definitions across applications within an EHR implementation project may be constrained by practical limitations, including time, tools, and expertise. However, maintaining rigor in an approach to data governance is important for sustainability and consistency. With this understanding, we have defined a practical approach for governance of structured data elements to optimize data definitions given limited resources. This approach includes a 10 step process: 1) identification of clinical topics, 2) creation of draft reference models for clinical topics, 3) scoring of downstream data needs for clinical topics, 4) prioritization of clinical topics, 5) validation of reference models for clinical topics, and 6) calculation of gap analyses of EHR compared against reference model, 7) communication of validated reference models across project members, 8) requested revisions to EHR based on gap analysis, 9) evaluation of usage of reference models across project, and 10) Monitoring for new evidence requiring revisions to reference model.

A Text-Mining Framework for Supporting Systematic Reviews.

PubMed

2016-11-01

Systematic reviews (SRs) involve the identification, appraisal, and synthesis of all relevant studies for focused questions in a structured reproducible manner. High-quality SRs follow strict procedures and require significant resources and time. We investigated advanced text-mining approaches to reduce the burden associated with abstract screening in SRs and provide high-level information summary. A text-mining SR supporting framework consisting of three self-defined semantics-based ranking metrics was proposed, including keyword relevance, indexed-term relevance and topic relevance. Keyword relevance is based on the user-defined keyword list used in the search strategy. Indexed-term relevance is derived from indexed vocabulary developed by domain experts used for indexing journal articles and books. Topic relevance is defined as the semantic similarity among retrieved abstracts in terms of topics generated by latent Dirichlet allocation, a Bayesian-based model for discovering topics. We tested the proposed framework using three published SRs addressing a variety of topics (Mass Media Interventions, Rectal Cancer and Influenza Vaccine). The results showed that when 91.8%, 85.7%, and 49.3% of the abstract screening labor was saved, the recalls were as high as 100% for the three cases; respectively. Relevant studies identified manually showed strong topic similarity through topic analysis, which supported the inclusion of topic analysis as relevance metric. It was demonstrated that advanced text mining approaches can significantly reduce the abstract screening labor of SRs and provide an informative summary of relevant studies.

Emerging topical onychomycosis therapies - quo vadis?

Elkeeb, Rania; Hui, Xiaoying; Murthy, Narasimha; Maibach, Howard I

2014-12-01

Onychomycosis, a common chronic fungal infection affecting fingernails and toenails, globally may affect 10 - 30% of the population. This chronic disease is difficult to eradicate. The goal of developing a highly effective and safe topical treatment has not yet been reached as it depends on the type of onychomycosis and the variety of invaders. Topical drug delivery to the nail is highly desirable in treating nail disorders. However, efficacy of topical therapies is low due to their limited permeability across the nail plate. Advances have especially been made by the development of new therapeutic options including new drug entities, new formulations and reformulations. This overview updates emerging topical treatments for onychomycosis, research progress and future perspectives. Development of novel effective noninvasive topical therapy for treating onychomycosis and other nail diseases such as psoriasis is long overdue. Previously there was a lack of basic knowledge about nail and its barrier properties, but with the recent increased interest in this field both from industry and academia, we hope extensive research will continue in this field to bring about successful and safe treatments for such chronic diseases.

Detecting Spatial Patterns of Natural Hazards from the Wikipedia Knowledge Base

NASA Astrophysics Data System (ADS)

Fan, J.; Stewart, K.

2015-07-01

The Wikipedia database is a data source of immense richness and variety. Included in this database are thousands of geotagged articles, including, for example, almost real-time updates on current and historic natural hazards. This includes usercontributed information about the location of natural hazards, the extent of the disasters, and many details relating to response, impact, and recovery. In this research, a computational framework is proposed to detect spatial patterns of natural hazards from the Wikipedia database by combining topic modeling methods with spatial analysis techniques. The computation is performed on the Neon Cluster, a high performance-computing cluster at the University of Iowa. This work uses wildfires as the exemplar hazard, but this framework is easily generalizable to other types of hazards, such as hurricanes or flooding. Latent Dirichlet Allocation (LDA) modeling is first employed to train the entire English Wikipedia dump, transforming the database dump into a 500-dimension topic model. Over 230,000 geo-tagged articles are then extracted from the Wikipedia database, spatially covering the contiguous United States. The geo-tagged articles are converted into an LDA topic space based on the topic model, with each article being represented as a weighted multidimension topic vector. By treating each article's topic vector as an observed point in geographic space, a probability surface is calculated for each of the topics. In this work, Wikipedia articles about wildfires are extracted from the Wikipedia database, forming a wildfire corpus and creating a basis for the topic vector analysis. The spatial distribution of wildfire outbreaks in the US is estimated by calculating the weighted sum of the topic probability surfaces using a map algebra approach, and mapped using GIS. To provide an evaluation of the approach, the estimation is compared to wildfire hazard potential maps created by the USDA Forest service.

Some important health policy topics, such as those related to the delivery, organization, and financing of health care, present substantial challenges to established methods for evidence synthesis. For example, such reviews may ask: What is the effect of for-profit versus not-for-profit delivery of care on patient outcomes? Or, which strategies are the most effective for promoting preventive care? This paper describes innovative methods for synthesizing evidence related to the delivery, organization, and financing of health care. We found 13 systematic reviews on these topics that described novel methodologic approaches. Several of these syntheses used 3 approaches: conceptual frameworks to inform problem formulation, systematic searches that included nontraditional literature sources, and hybrid synthesis methods that included simulations to address key gaps in the literature. As the primary literature on these topics expands, so will opportunities to develop additional novel methods for performing high-quality comprehensive syntheses.

Topical Prophylaxis for HIV Prevention in Women: Becoming a Reality

PubMed Central

Verma, Natasha A.; Lee, Anna C.; Herold, Betsy C.

2011-01-01

Strategies to protect against sexual transmission of HIV include the development of products formulated for topical application, which limit the toxicities associated with systemic oral pre-exposure prophylaxis. Following several clinical trial failures, attention is now focused on antiretroviral (ARV) agents. Highly potent ARV topical formulations provide a female-controlled, targeted, and feasible option for HIV prevention. A recently completed tenofovir gel trial was the first to demonstrate significant protection against HIV acquisition. Topical ARVs have the advantage of delivering high concentration of drug at the site of transmission of HIV, with low systemic absorption. Sustained-release formulations, such as intravaginal rings, will likely improve adherence and can be designed to provide controlled and continuous delivery of ARV combinations. Further studies to test alternative dosing strategies and pharmacokinetic/pharmacodynamic relationships in the genital tract will provide valuable information as the field strives to improve upon the promising tenofovir gel trial results.

Topical gels compounded by pharmacists are important clinical tools for the management of pain. Nevertheless, there is often a dearth of information about the chemical stability of drugs included in these topical formulations, complicating the assignment of beyond-use dating. The purpose of this study was to develop a high-performance liquid chromatography photodiode array-based stability-indicating assay that could simultaneously resolve six drugs (amitriptyline, baclofen, clonidine, gabapentin, ketoprofen, lidocaine) commonly included in topical gels for pain management and their potential degradation products. Furthermore, this method was applied to the determination of beyond-use dating of combinations of these drugs prepared in commonly utilized bases (Lipobase, Lipoderm, Pluronic organogel). Gabapentin was determined to be the least stable component in all formulations tested. Measured stability ranged between 7 to 49 days depending on the base and other active drugs present in the formulation. In the absence of gabapentin, baclofen was the next least stable component, lasting for 120 days, regardless of the type of formulating base used.

Study Objectives: To identify and prioritize future research needs (FRN) topics for diagnosis and treatment of obstructive sleep apnea (OSA). Methods: Twenty-one panel members represented six stake-holder categories: patients and the public, providers; purchasers of health care, payers, policymakers, and principal investigators. Building on a recently completed comparative effectiveness review, stakeholders nominated and discussed potential FRN topics. Stakeholders then nominated their top priority FRN topics based on the Agency for Healthcare Research and Quality Effective Health Care Program Selection Criteria. From these nominations, the highest priority FRN topics were determined and were elaborated upon to include possible study designs to address the topics. Results: Thirty-seven topics were discussed and prioritized. The nine highest priority FRN topics included: cost-effectiveness of management strategies, defining age- and sex-specific criteria for OSA, evaluating routine preoperative screening for OSA, evaluating involvement of a sleep medicine specialist in diagnosis of OSA, evaluating clinical prediction rules, assessing the effect of treating sleep disordered breathing and long-term clinical outcomes, comparing treatments for patients who do not tolerate positive airway pressure, evaluating strategies to improve treatment compliance, and evaluating the association between sleep apnea severity and long-term clinical outcomes. Conclusions: While there are numerous specific research questions with low or insufficient strength of evidence for OSA management, OSA patients, their healthcare providers, and society at large would benefit from refocusing research efforts into the prioritized research questions and away from simple comparisons of short-term outcomes between specific interventions.

2013-09-01

Computed tomography (CT) is the modality of choice for imaging the lungs in vivo. Sub-millimeter isotropic images of the lungs can be obtained within seconds, allowing the detection of small lesions and detailed analysis of disease processes. The high resolution of thoracic CT and the high prevalence of lung diseases require a high degree of automation in the analysis pipeline. The automated segmentation of pulmonary structures in thoracic CT has been an important research topic for over a decade now. This systematic review provides an overview of current literature. We discuss segmentation methods for the lungs, the pulmonary vasculature, the airways, including airway tree construction and airway wall segmentation, the fissures, the lobes and the pulmonary segments. For each topic, the current state of the art is summarized, and topics for future research are identified.

2013-05-01

Sexuality education teachers' perspectives are important to gain a full understanding of the issues surrounding teaching this subject. This study uses a statewide sample of public school teachers to examine what sexuality education content is taught, what barriers teachers face, and which barriers are associated with teaching specific topics. Participants included 368 middle and high school teachers with sexuality education assignments in Minnesota. Survey data included topics they teach, what they think they should teach, and barriers they face. Logistic regression was used to examine associations between barriers and teaching each of 9 sexual health topics, among those who believed the topic should be taught. Almost two thirds of participants faced structural barriers; 45% were concerned about parent, student, or administrator response; and one quarter reported restrictive policies. Structural barriers were inversely associated with teaching about communication (OR = 0.20), teen parenting (OR = 0.34), and abortion (OR = 0.32); concerns about responses were associated only with teaching about sexual violence (OR = 0.42); and restrictive policies were inversely associated with teaching about abortion (OR = 0.23) and sexual orientation (OR = 0.47). Addressing teachers' barriers requires a multipronged approach, including curriculum development and evaluation, training, and reframing the policy debate to support a wider range of sexuality education topics. © 2013, American School Health Association.

Recommendations for teaching upon sensitive topics in forensic and legal medicine in the context of medical education pedagogy.

PubMed

Kennedy, Kieran M; Scriver, Stacey

2016-11-01

Undergraduate medical curricula typically include forensic and legal medicine topics that are of a highly sensitive nature. Examples include suicide, child abuse, domestic and sexual violence. It is likely that some students will have direct or indirect experience of these issues which are prevalent in society. Those students are vulnerable to vicarious harm from partaking in their medical education. Even students with no direct or indirect experience of these issues may be vulnerable to vicarious trauma, particularly students who are especially empathetic to cases presented. Despite these risks, instruction relating to these topics is necessary to ensure the competencies of graduating doctors to respond appropriately to cases they encounter during their professional careers. However, risk can be minimised by a well-designed and thoughtfully delivered educational programme. We provide recommendations for the successful inclusion of sensitive forensic and legal medicine topics in undergraduate medical curricula.

Ahmad, Hesham M; Abdel-Azim, Eman S; Abdel-Aziz, Rasha T

2016-01-01

Many medications are available for scabies treatment including oral and topical ivermectin. However, studies comparing these two forms as a scabies treatment are few. This study compares efficacy and safety of topical versus oral ivermectin as scabies treatment. The study included 62 confirmed uncomplicated scabies patients, divided into: Group I (32 patients, received topical ivermectin) and Group II (30 patients, received oral ivermectin). Patients were assessed, clinically and by KOH smear at 1, 2 and 4 weeks. Treatment was repeated after one week in patients with persistent infection. Adverse events were recorded. Most patients (87.5% and 73.5% in group I and group II respectively) were symptom free after a single treatment. A second treatment was required in 4 patients of group I and 8 patients of group II. However, 2 weeks after treatment symptoms and signs completely resolved in all cases with no recurrence at 4 weeks. This study suggests that both topical and oral ivermectin are safe and equally effective in treatment of uncomplicated scabies. Single treatment, whether topical or oral, is associated with high cure rate in a week post treatment. However, repeating treatment after one week may be required to achieve 100% cure. © 2015 Wiley Periodicals, Inc.

Rhodes, Darson L; Kirchofer, Gregg; Hammig, Bart J; Ogletree, Roberta J

2013-05-01

This study examined the impact of professional preparation and class structure on sexuality topics taught and use of practice-based instructional strategies in US middle and high school health classes. Data from the classroom-level file of the 2006 School Health Policies and Programs were used. A series of multivariable logistic regression models were employed to determine if sexuality content taught was dependent on professional preparation and /or class structure (HE only versus HE/another subject combined). Additional multivariable logistic regression models were employed to determine if use of practice-based instructional strategies was dependent upon professional preparation and/or class structure. Years of teaching health topics and size of the school district were included as covariates in the multivariable logistic regression models. Findings indicated professionally prepared health educators were significantly more likely to teach 7 of the 13 sexuality topics as compared to nonprofessionally prepared health educators. There was no statistically significant difference in the instructional strategies used by professionally prepared and nonprofessionally prepared health educators. Exclusively health education classes versus combined classes were significantly more likely to have included 6 of the 13 topics and to have incorporated practice-based instructional strategies in the curricula. This study indicated professional preparation and class structure impacted sexuality content taught. Class structure also impacted whether opportunities for students to practice skills were made available. Results support the need for continued advocacy for professionally prepared health educators and health only courses. © 2013, American School Health Association.

The aim of the paper is the presentation of an interdisciplinary topic that allows applying content knowledge in physics, mathematics and biology in real life environment. Students use to play games and view crime scenes but in common they have little knowledge about the science used during crime scene investigation. In this paper the science background of blood spatter analysis is presented—the physics of non-Newtonian fluids, the biology of blood and mathematics—the measurement and calculation of the angle of inpact, the relationship between height and spatter diameter. This topic was choosen according to the analysis of interviews with secondary and high school learners realized at four schools in Moravia, Czech Republic. The topic can be taught at secondary schools so as at a higher level at high schools. Hands-on activities are included. The teaching strategy supports group work. The appropriateness and reasonableness of the topic was checked in the real teaching process and the activities have had a positive feedback.

In particular, neuropathic pain is a major form of chronic pain. This type of pain results from dysfunction or lesions in the central and peripheral nervous system. Capsaicin has been traditionally utilized as a medicine to remedy pain. However, the effectiveness and safety of this practice is still elusive. Therefore, this systematic review aimed to investigate the effect of topical capsaicin as a pain-relieving agent that is frequently used in pain management. In brief, all the double-blinded, randomized placebo- or vehicle-controlled trials that were published in English addressing postherpetic neuralgia were included. Meta-analysis was performed using Revman® version 5.3. Upon application of the inclusion and exclusion criteria, only six trials fulfilled all the criteria and were included in the review for qualitative analysis. The difference in mean percentage change in numeric pain rating scale score ranges from -31 to -4.3. This demonstrated high efficacy of topical capsaicin application and implies that capsaicin could result in pain reduction. Furthermore, meta-analysis was performed on five of the included studies. All the results of studies are in favor of the treatment using capsaicin. The incidence of side effects from using topical capsaicin is consistently higher in all included studies, but the significance of safety data cannot be quantified due to a lack of p-values in the original studies. Nevertheless, topical capsaicin is a promising treatment option for specific patient groups or certain neuropathic pain conditions such as postherpetic neuralgia. PMID:28119613

The purpose of this study was to compare the level of patient pain during the phacoemulsification and implantation of foldable intraocular lenses while under topical, intracameral, or sub-Tenon lidocaine. This was a retrospective study. Three hundred and one eyes subjected to cataract surgery were included in this study. All eyes underwent phacoemulsification surgery and intraocular lens implantation using topical, sub-Tenon, or intracameral anesthesia. The topical group received 4% lidocaine drops, and the intracameral group received a 0.1-0.2 cc infusion of 1% preservative-free lidocaine into the anterior chamber through the side port combined with topical drops of lidocaine. The sub-Tenon group received 2% lidocaine. Best-corrected visual acuity, corneal endothelial cell loss, and intraoperative pain level were evaluated. Pain level was assessed on a visual analog scale (range 0-2). There were no significant differences in visual outcome and corneal endothelial cell loss between the three groups. The mean pain score in the sub-Tenon group was significantly lower than that in the topical and intracameral groups (P=0.0009 and P=0.0055, respectively). In 250 eyes without high myopia (< -6D), there were no significant differences in mean pain score between the sub-Tenon and intracameral groups (P=0.1417). No additional anesthesia was required in all groups. Intracameral lidocaine provides sufficient pain suppressive effects in eyes without high myopia, while sub-Tenon anesthesia is better for cataract surgery in eyes with high myopia.

Potential Allergens in Disposable Diaper Wipes, Topical Diaper Preparations, and Disposable Diapers: Under-recognized Etiology of Pediatric Perineal Dermatitis.

PubMed

Yu, JiaDe; Treat, James; Chaney, Keri; Brod, Bruce

2016-01-01

Allergic contact dermatitis in young children may be an under-recognized cause of perineal dermatitis. The diapered infant skin is uniquely susceptible to allergic contact dermatitis because of more permeable neonatal skin, a moist environment, frequent contact with irritants and resultant skin barrier breakdown, and exposure to topical products such as diaper wipes, diaper preparations, and disposable diapers. To our knowledge, potential allergens in these products have not been thoroughly catalogued or studied. We explore and review potential allergenic ingredients in diaper wipes, topical diaper preparations, and disposable diapers. We analyzed 63 diaper wipes, 41 topical diaper preparations, and the 3 top selling diaper brands available from two of the largest retailers in the United States. Each potential allergen is discussed, and epidemiologic studies of rates of sensitization to potential allergens in children are also reported. Botanical extracts, including members of the Compositae family, were the most commonly represented potential allergen in both diaper wipes and topical preparations. Other potential allergens identified with high frequency include α-tocopherol, fragrances, propylene glycol, parabens, iodopropynyl butylcarbamate, and lanolin. Frequent culprits such as formaldehyde releasers and methylchloroisothiazolinone/methylisothiazolinone were not prevalent in our analyzed products.

Developing topic-specific search filters for PubMed with click-through data.

Li, J; Lu, Z

2013-01-01

Search filters have been developed and demonstrated for better information access to the immense and ever-growing body of publications in the biomedical domain. However, to date the number of filters remains quite limited because the current filter development methods require significant human efforts in manual document review and filter term selection. In this regard, we aim to investigate automatic methods for generating search filters. We present an automated method to develop topic-specific filters on the basis of users' search logs in PubMed. Specifically, for a given topic, we first detect its relevant user queries and then include their corresponding clicked articles to serve as the topic-relevant document set accordingly. Next, we statistically identify informative terms that best represent the topic-relevant document set using a background set composed of topic irrelevant articles. Lastly, the selected representative terms are combined with Boolean operators and evaluated on benchmark datasets to derive the final filter with the best performance. We applied our method to develop filters for four clinical topics: nephrology, diabetes, pregnancy, and depression. For the nephrology filter, our method obtained performance comparable to the state of the art (sensitivity of 91.3%, specificity of 98.7%, precision of 94.6%, and accuracy of 97.2%). Similarly, high-performing results (over 90% in all measures) were obtained for the other three search filters. Based on PubMed click-through data, we successfully developed a high-performance method for generating topic-specific search filters that is significantly more efficient than existing manual methods. All data sets (topic-relevant and irrelevant document sets) used in this study and a demonstration system are publicly available at http://www.ncbi.nlm.nih.gov/CBBresearch/Lu/downloads/CQ_filter/

Vesiculo-erosive oral mucosal disease--management with topical corticosteroids: (1) Fundamental principles and specific agents available.

PubMed

González-Moles, M A; Scully, C

2005-04-01

Vesiculo-erosive diseases of the oral mucosa pose a major challenge in oral medicine, because they are chronic, painful, and interfere with the daily activities and quality of life of the patients, including disturbing eating, drinking, talking, and personal relationships. Many are autoimmune diseases, and corticosteroid therapy is currently central to their treatment. These diseases present with inflammation and alterations to epithelial integrity, through cell and/or humoral immunity-mediated attack on epithelial-connective tissue targets. Until recently, despite their serious adverse effects, it was necessary to prescribe systemic corticosteroids to control severe erosive oral diseases. Now, however, many of these diseases can be controlled by high-potency topical corticosteroids, which have proved to be highly efficacious and to cause fewer adverse effects compared with systemic corticosteroids. Nevertheless, although topical corticosteroids are still the most widely used drugs in the practice of oral medicine, the scientific body of evidence for their use in the oral cavity is virtually non-existent, and therefore many of the protocols followed are, of necessity, drawn from experience of their use in a dermatological setting. This review aims to set out the key aspects of the use of topical corticosteroids in oral medicine. The issues covered include the indications and basic rules for their use, the types of corticosteroids, the drug selection, and the specific formulations.

Eglseer, Doris; Halfens, Ruud J G; Schüssler, Sandra; Visser, Marjolein; Volkert, Dorothee; Lohrmann, Christa

2018-05-26

The lack of sufficient knowledge of health care professionals is one main barrier to implementing adequate nutritional interventions. Until now, it is not known to which extent European nurses are exposed to the topic of malnutrition in older adults during their education. To determine whether formal nursing degree programs in Europe address the topic of nutrition and, specifically, malnutrition in older adults. A cross-sectional study was conducted using an online-survey. The online-survey link was e-mailed to 926 nursing education institutions in 31 European countries. This study was conducted as part of the Healthy Diet for Healthy Life Joint Programming Initiative, Malnutrition in the Elderly Knowledge Hub (MaNuEL) project. Descriptive analyses were performed using SPSS. Associations were calculated using the chi-square tests and Fisher's exact test. The response rate of our survey was 14.2% (131 institutions). Of these, 113 (86.3%) addressed the topic of nutrition in their educational programs, and 73.7% addressed the topic of malnutrition in older adults. Malnutrition screening (70.8%), causes (67.2%) and consequences (68.7%) of malnutrition were frequently-addressed topics of content. Topics that were rarely addressed included nutritional support in intensive care units (ICU) (23.7%), cooperation in multidisciplinary nutrition teams (28.2%), dietary counselling (32.1%) and the responsibilities of various professions in nutritional support (35.1%). The topic of malnutrition in older adults is taught by nurses in 52.7%, by dietitians in 23.7%, by nutritional scientists in 18.3%, and physicians in 19.8% of the institutions. The topics of malnutrition and malnutrition screening are currently not included in the content of nutrition courses taught at nearly 30% of the European educational institutions for nurses. Nursing educators urgently need to improve curriculum content with respect to the topic of malnutrition in older adults to enable nurses to provide high-quality nutritional care of older persons.

Topical Treatment of Degenerative Knee Osteoarthritis.

PubMed

Meng, Zengdong; Huang, Rongzhong

2018-01-01

This article reviews topical management strategies for degenerative osteoarthritis (OA) of the knee. A search of Pubmed, Embase and the Cochrane library using MeSH terms including "topical," "treatment," "knee" and "osteoarthritis" was carried out. Original research and review articles on the effectiveness and safety, recommendations from international published guidelines and acceptability studies of topical preparations were included. Current topical treatments included for the management of knee OA include topical nonsteroidal anti-inflammatory drugs, capsaicin, salicylates and physical treatments such as hot or cold therapy. Current treatment guidelines recommend topical nonsteroidal anti-inflammatory drugs as an alternative and even first-line therapy for OA management, especially among elderly patients. Guidelines on other topical treatments vary, from recommendations against their use, to in favor as alternative or simultaneous therapy, especially for patients with contraindications to other analgesics. Although often well-tolerated and preferred by many patients, clinical care still lags in the adoption of topical treatments. Aspects of efficacy, safety and patient quality of life data require further research. Copyright © 2018 Southern Society for Clinical Investigation. Published by Elsevier Inc. All rights reserved.

2010-05-01

This article discusses the identification, selection, and refinement of topics for comparative effectiveness systematic reviews within the Agency for Healthcare Research and Quality's Effective Health Care (EHC) program. The EHC program seeks to align its research topic selection with the overall goals of the program, impartially and consistently apply predefined criteria to potential topics, involve stakeholders to identify high-priority topics, be transparent and accountable, and continually evaluate and improve processes. A topic prioritization group representing stakeholder and scientific perspectives evaluates topic nominations that fit within the EHC program (are "appropriate") to determine how "important" topics are as considered against seven criteria. The group then judges whether a new comparative effectiveness systematic review would be a duplication of existing research syntheses, and if not duplicative, if there is adequate type and volume of research to conduct a new systematic review. Finally, the group considers the "potential value and impact" of a comparative effectiveness systematic review. As the EHC program develops, ongoing challenges include ensuring the program addresses truly unmet needs for synthesized research because national and international efforts in this arena are uncoordinated, as well as engaging a range of stakeholders in program decisions while also achieving efficiency and timeliness.

The "TOPical Imiquimod treatment of high-grade Cervical intraepithelial neoplasia" (TOPIC) trial was stopped preliminary, due to lagging inclusions. This study aimed to evaluate the treatment efficacy and clinical applicability of imiquimod 5% cream in high-grade cervical intraepithelial neoplasia (CIN). The lagging inclusions were mainly due to a strong patient preference for either of the two treatment modalities. This prompted us to initiate a new study on the same subject, with a non-randomized, open-label design: the 'TOPical Imiquimod treatment of high-grade Cervical intraepithelial neoplasia (TOPIC)-3' study. Original TOPIC-trial: Medical Ethics Committee approval number METC13231; ClinicalTrials.gov Identifier: NCT02329171, 22 December 2014.

2016-11-14

Scabies is a contagious infestation transmitted by skin-to-skin contact and sometimes by contact with contaminated material. The scabies mite burrows into the skin, producing a papular rash and severe itch at typical sites of predilection. We systematically reviewed the literature to compare the efficacy of various anti-scabies agents, including a calculation of relative risks and confidence intervals. A literature search yielded 596 initial hits; after screening in accor-dance with the defined inclusion and exclusion criteria, 16 studies were selected for this review. Among topical treatments for scabies, permethrin was equally effective or more effective than crotamiton or benzyl benzoate. In a comparison of topical versus systemic treatment, topical permethrin and systemic ivermectin did not differ substantially in efficacy (7 comparative studies revealed no difference; one revealed a difference in favor of permethrin). Comparative trials of topical benzyl benzoate versus systemic ivermectin yielded inconsistent findings. Single and double administrations of ivermectin were similarly effective. In trials involving entire populations with a high prevalence of scabies, systemic ivermectin was found to be superior to topical permethrin. There are hardly any differences in efficacy between the available treatments for scabies. Single administrations of permethrin 5%, crotamiton 10%, and systemic ivermectin are all comparably effective. There are differences in the frequeny and ease of application as well as when eradicating scabies in populations with a high prevalence.

Barriers to Incorporating Climate Change Science into High School and Community College Energy Course Offerings

NASA Astrophysics Data System (ADS)

Howell, C.

2013-05-01

In reviewing studies evaluating trends in greenhouse gasses, weather, climate and/or ecosystems, it becomes apparent that climate change is a reality. It has also become evident that the energy sector accounts for most of the greenhouse gas emissions with worldwide emissions of carbon dioxide increasing by 31 percent from 1990 to 2005, higher than in the previous thousands of years. While energy courses and topics are presented in high school and community college classes the topic of Climate Change Science is not always a part of the conversation. During the summer of 2011 and 2012, research undergraduates conducted interviews with a total of 39 national community college and 8 high school instructors who participated in a two week Sustainable Energy Education Training (SEET) workshop. Interview questions addressed the barriers and opportunities to the incorporation of climate change as a dimension of an energy/renewable energy curriculum. Barriers found included: there is not enough instruction time to include it; some school administrators including community members do not recognize climate change issues; quality information about climate change geared to students is difficult to find; and, most climate change information is too scientific for most audiences. A Solution to some barriers included dialogue on sustainability as a common ground in recognizing environmental changes/concerns among educators, administrators and community members. Sustainability discussions are already supported in school business courses as well as in technical education. In conclusion, we cannot expect climate change to dissipate without humans making more informed energy and environmental choices. With global population growth producing greater emissions resulting in increased climate change, we must include the topic of climate change to students in high school and community college classrooms, preparing our next generation of leaders and workforce to be equipped to find solutions, (such as renewable energy and sustainability practices), to climate change and environmental sustainability.

Topical phenytoin for treating pressure ulcers.

PubMed

Hao, Xiang Yong; Li, Hong Ling; Su, He; Cai, Hui; Guo, Tian Kang; Liu, Ruifeng; Jiang, Lei; Shen, Yan Fei

2017-02-22

Pressure ulcers are common in clinical practice and pose a significant health problem worldwide. Apart from causing suffering to patients, they also result in longer hospital stays and increase the cost of health care. A variety of methods are used for treating pressure ulcers, including pressure relief, patient repositioning, biophysical strategies, nutritional supplementation, debridement, topical negative pressure, and local treatments including dressings, ointments and creams such as bacitracin, silver sulphadiazine, neomycin, and phenytoin. Phenytoin is a drug more commonly used in the treatment of epilepsy, but may play an important role in accelerating ulcer healing. To assess the effects of topical phenytoin on the rate of healing of pressure ulcers of any grade, in any care setting. In September 2016, we searched the following electronic databases to identify relevant randomized clinical trials: the Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL; the Cochrane Library); Ovid MEDLINE; Ovid Embase; and EBSCO CINAHL Plus. We handsearched conference proceedings from the European Pressure Ulcer Advisory Panel, European Wound Management Association and the Tissue Viability Society for all available years. We searched the references of the retrieved trials to identify further relevant trials. We also searched clinical trials registries to identify ongoing and unpublished studies. There were no restrictions with respect to language, date of publication or study setting. We included all randomized controlled trials (RCTs) addressing the effects (both benefits and harms) of topical phenytoin on the healing of pressure ulcers of any grade compared with placebo or alternative treatments or no therapy, irrespective of blinding, language, and publication status. Two review authors independently selected studies, extracted information on participants, interventions, methods and results and assessed risk of bias using Cochrane methodological procedures. For dichotomous variables, we calculated the risk ratio (RR) with 95% confidence interval (CI). For continuous variables, we calculated the mean difference with 95% CI. We rated the quality of the evidence by using Grading of Recommendations, Assessment, Development and Evaluation approach (GRADE). Three small RCTs met our inclusion criteria and included a total of 148 participants. These compared three treatments with topical phenytoin: hydrocolloid dressings, triple antibiotic ointment and simple dressings. In the three RCTs, 79% of participants had grade II ulcers, and 21% of participants had grade I ulcers; no participants had grade III or IV ulcers. Two RCTs had a high risk of bias overall and the other RCT was at unclear risk of bias due to poor reporting. Two RCTs had three intervention arms and the other had two intervention arms.Two studies compared topical phenytoin with hydrocolloid dressing (84 participants analysed). The available data suggest that hydrocolloid dressings may improve ulcer healing compared to topical phenytoin (39.3% ulcers healed for phenytoin versus 71.4% ulcers healed for hydrocolloid dressings (RR 0.55, 95% CI 0.33 to 0.92; 56 participants, 1 study; low quality evidence). We downgraded the evidence twice: once due to serious limitations (high risk of bias) and once due to the small sample size and small number of events. Two studies compared topical phenytoin with simple dressings (81 participants analysed). From the available data, we are uncertain whether topical phenytoin improves ulcer healing compared to simple dressings (39.3% ulcers healed for phenytoin versus 29.6% ulcers healed for the simple dressing (RR 1.33, 95% CI 0.63 to 2.78; 55 participants, 1 study; very low quality evidence). This evidence was downgraded once due to serious limitations (high risk of bias) and twice due to the low number of outcome events and resulting wide CI which included the possibility of both increased healing and reduced healing. We therefore considered it to be insufficient to determine the effect of topical phenytoin on ulcer healing. One study compared topical phenytoin with triple antibiotic ointment, however, none of the outcomes of interest to this review were reported. No adverse drug reactions or interactions were detected in any of the three RCTs. Minimal pain was reported in all groups in one trial that compared topical phenytoin with hydrocolloid dressings and triple antibiotic ointment. This review has considered the available evidence and the result shows that it is uncertain whether topical phenytoin improves ulcer healing for patients with grade I and II pressure ulcers. No adverse events were reported from three small trials and minimal pain was reported in one trial. Therefore, further rigorous, adequately powered RCTs examining the effects of topical phenytoin for treating pressure ulcers, and to report on adverse events, quality of life and costs are necessary.

Unified Aeroacoustics Analysis for High Speed Turboprop Aerodynamics and Noise. Volume 1; Development of Theory for Blade Loading, Wakes, and Noise

NASA Technical Reports Server (NTRS)

Hanson, D. B.

1991-01-01

A unified theory for the aerodynamics and noise of advanced turboprops are presented. Aerodynamic topics include calculation of performance, blade load distribution, and non-uniform wake flow fields. Blade loading can be steady or unsteady due to fixed distortion, counter-rotating wakes, or blade vibration. The aerodynamic theory is based on the pressure potential method and is therefore basically linear. However, nonlinear effects associated with finite axial induction and blade vortex flow are included via approximate methods. Acoustic topics include radiation of noise caused by blade thickness, steady loading (including vortex lift), and unsteady loading. Shielding of the fuselage by its boundary layer and the wing are treated in separate analyses that are compatible but not integrated with the aeroacoustic theory for rotating blades.

Feasibility of Topical Applications of Natural High-Concentration Capsaicinoid Solutions in Patients with Peripheral Neuropathic Pain: A Retrospective Analysis.

PubMed

Bauchy, Fanny; Mouraux, Andre; Deumens, Ronald; Leerink, Marjolein; Ulpiano Trillig, Antonio; le Polain de Waroux, Bernard; Steyaert, Arnaud; Joëlle, Quetin-Leclercq; Forget, Patrice

2016-01-01

Background. Capsaicin, one of several capsaicinoid compounds, is a potent TRPV1 agonist. Topical application at high concentration (high concentration, >1%) induces a reversible disappearance of epidermal free nerve endings and is used to treat peripheral neuropathic pain (PNP). While the benefit of low-concentration capsaicin remains controversial, the 8%-capsaicin patch (Qutenza®, 2010, Astellas, Netherlands) has shown its effectiveness. This patch is, however, costly and natural high-concentration capsaicinoid solutions may represent a cheaper alternative to pure capsaicin. Methods. In this retrospective study, 149 patients were screened, 132 were included with a diagnosis of neuropathic pain, and eighty-four were retained in the final analyses (median age: 57.5 years [IQR25-75: 44.7-67.1], male/female: 30/54) with PNP who were treated with topical applications of natural high-concentration capsaicinoid solutions (total number of applications: 137). Indications were postsurgical PNP (85.7%) and nonsurgical PNP (14.3%) (posttraumatic, HIV-related, postherpetic, and radicular PNP). Objectives. To assess the feasibility of topical applications of natural high-concentration capsaicinoid solutions for the treatment of PNP. Results. The median treated area was 250 cm 2 [IQR25-75: 144-531]. The median amount of capsaicinoids was 55.1 mg [IQR25-75: 28.7-76.5] per plaster and the median concentration was 172.3  μ g/cm 2 [IQR25-75: 127.6-255.2]. Most patients had local adverse effects on the day of treatment, such as mild to moderate burning pain and erythema. 13.6-19.4% of the patients experienced severe pain or erythema. Following treatment, 62.5% of patients reported a lower pain intensity or a smaller pain surface, and 35% reported a sustained pain relief lasting for at least 4 weeks. Conclusion. Analgesic topical treatment with natural high-concentration capsaicinoid is feasible and may represent a low cost alternative to alleviate PNP in clinical practice.

Gaisser, and Todor Stanev, two postdoctoral fellows (Ilia Gogoladze and Liucheng Wang), and several graduate students. Five students of Qaisar Shafi completed their PhD during the period August 2011 - August 2014. Measures of themore » group’s high caliber performance during the 2012-2015 funding cycle included pub- lications in excellent refereed journals, contributions to working groups as well as white papers, and conference activities, which together provide an exceptional record of both individual performance as well as overall strength. Another important indicator of success is the outstanding quality of the past and current cohort of graduate students. The PhD students under our supervision regularly win the top departmental and university awards, and their publications records show excellence both in terms of quality and quantity. The topics covered under this grant cover the frontline research areas in today’s High Energy Theory & Phenomenology. For Professors Shafi and Barr they include LHC related topics including supersymmetry, collider physics, fl vor physics, dark matter physics, Higgs boson and seesaw physics, grand unifi and neutrino physics. The LHC two years ago discovered the Standard Model Higgs boson, thereby at least partially unlocking the secrets behind electroweak symmetry breaking. We remain optimistic that new and exciting physics will be found at LHC 14, which explain our focus on physics beyond the Standard Model. Professors Shafi continued his investigations in cosmology, specifically on supergravity and GUT infl models, primordial gravity waves, dark matter models. The origin of baryon and dark matter in the universe has been explored by Professors Barr and Shafi The research program of Professors Gaisser and Stanev address current research topics in Particle Astrophysics, in particular atmospheric and cosmogenic neutrinos and ultra-high energy cosmic rays. Work also included use of LHC data to improve tools for interpreting cascades generated in the atmosphere by high-energy particles from the cosmos. Cosmogenic neutrinos produced by interactions of ultra-high energy cosmic rays as they propagate through the cosmic microwave background radiation provides insight into the origin of the highest energy particles in nature.

Interest in biology. Part I: A multidimensional construct

NASA Astrophysics Data System (ADS)

Gardner, Paul L.; Tamir, Pinchas

Interest in a school subject (e.g., biology) is conceptualized in terms of three components: topics, activities, and motives, each of which has several dimensions. In this study, seven instruments were developed and administered to grade-10 biology students in Israel. Factor analysis provided support for the conceptualization which underlies the development of the instruments. Topic dimensions included biochemical processes, nonhuman organisms, human biology, personal hygiene, and practical applications; the activity dimensions were experiential learning, reception learning, writing/summarizing and group discussion; motives included environmental issues, moral issues, examination success, personal independence, problem solving, and four career dimensions (research, high-status professions, lower-status careers, woodsy-birdsy careers). In an analysis described in Part II of this paper, the students were classified into four groups on the basis of their grade-11 subject enrollment intentions: H (high-level biology), L (low-level biology), P (physical science), and N (no science). Zero-order and multiple correlations were found between interest and other variables and membership/nonmembership of the four groups. Students in Group H were characterized by higher achievement in year-10 biology, higher levels of enjoyment of biology, career orientations towards research or high-status biology-based professions, greater interest in various biology topics, especially reproduction/cell division/genetics, and a greater tendency to regard the Bagrut (grade-12) examination as interesting. Students in Group N displayed lower levels of interest in various topics (especially the microscope, plants, and reproduction), were less motivated to solve problems, had poorer grades in biology (and chemistry), were less likely to perceive biology as useful, were less likely to regard the Bagrut examination as fair, and were less likely to be interested in social modes of learning. There were few associations between interest variables and membership in Groups L or P.

UHMS position statement: topical oxygen for chronic wounds.

PubMed

Feldmeier, J J; Hopf, H W; Warriner, R A; Fife, C E; Gesell, L B; Bennett, M

2005-01-01

A small body of literature has been published reporting the application of topical oxygen for chronic non-healing wounds . Frequently, and erroneously, this form of oxygen administration has been referred to as "topical hyperbaric oxygen therapy" or even more erroneously "hyperbaric oxygen therapy." The advocates of topical oxygen claim several advantages over systemic hyperbaric oxygen including decreased cost, increased safety, decreased complications and putative physiologic effects including decreased free radical formation and more efficient delivery of oxygen to the wound surface. With topical oxygen an airtight chamber or polyethylene bag is sealed around a limb or the trunk by either a constriction/tourniquet device or by tape and high flow (usually 10 liters per minute) oxygen is introduced into the bag and over the wound. Pressures just over 1.0 atmospheres absolute (atm abs) (typically 1.004 to 1.013 atm abs) are recommended because higher pressures could decrease arterial/capillary inflow. The premise for topical oxygen, the diffusion of oxygen into the wound adequate to enhance healing, is attractive (though not proven) and its delivery is certainly less complex and expensive than hyperbaric oxygen. When discussing the physiology of topical oxygen, its proponents frequently reference studies of systemic hyperbaric oxygen suggesting that mechanisms are equally applicable to both topical and systemic high pressure oxygen delivery. In fact, however, the two are very different. To date, mechanisms of action whereby topical oxygen might be effective have not been defined or substantiated. Conversely, cellular toxicities due to extended courses of topical oxygen have been reported, although, again these data are not conclusive, and no mechanism for toxicity has been examined scientifically. Generally, collagen production and fibroblast proliferation are considered evidence of improved healing, and these are both enhanced by hyperbaric oxygen therapy. Paradoxically, claims of decreased collagen production and fibroblast inhibition in wounds subjected to topical oxygen have been reported in studies of topical oxygen as a benefit of topical oxygen therapy. The literature on topical oxygen is mostly small case series or small controlled but not randomized trials. Moreover, the studies generally are not aimed at specific ulcer types, but rather at "chronic wounds." This non-specific approach is recognized as a major design flaw in any study of therapies designed to improve impaired wound healing. The only randomized trial for topical oxygen in diabetic foot ulcers actually showed a tendency toward impaired wound healing in the topical oxygen group. Contentions that topical oxygen is superior to hyperbaric oxygen are not proven. There are potentially plausible mechanisms that support both possibly beneficial and detrimental effects of topical oxygen therapy, and thus well designed and executed basic science research and clinical trials are clearly needed. There is some ongoing research in regard to the role of topical oxygen at established wound laboratories. Neither CMS nor other third party payors recognize or reimburse for topical oxygen. Therefore, the policy of the Undersea and Hyperbaric Medical Society in regard to topical oxygen is stated as follows: 1. Topical oxygen should not be termed hyperbaric oxygen since doing so either intentionally or unintentionally suggests that topical oxygen treatment is equivalent or even identical to hyperbaric oxygen. Published documents reporting experience with topical oxygen should clearly state that topical oxygen not hyperbaric oxygen is being employed. 2. Mechanisms of action or clinical study results for hyperbaric oxygen cannot and should not be co-opted to support topical oxygen since hyperbaric oxygen therapy and topical oxygen have different routes and probably efficiencies of entry into the wound and their physiology and biochemistry are necessarily different. 3. The application of topical oxygen cannot be recommended outside of a clinical trial at this time based on the volume and quality of scientific supporting evidence available, nor does the Society recommend third party payor reimbursement. 4. Before topical oxygen can be recommended as therapy for non-healing wounds, its application should be subjected to the same intense scientific scrutiny to which systemic hyperbaric oxygen has been held.

The Structure of Scientific Arguments by Secondary Science Teachers: Comparison of experimental and historical science topics

NASA Astrophysics Data System (ADS)

Gray, Ron; Kang, Nam-Hwa

2014-01-01

Just as scientific knowledge is constructed using distinct modes of inquiry (e.g. experimental or historical), arguments constructed during science instruction may vary depending on the mode of inquiry underlying the topic. The purpose of this study was to examine whether and how secondary science teachers construct scientific arguments during instruction differently for topics that rely on experimental or historical modes of inquiry. Four experienced high-school science teachers were observed daily during instructional units for both experimental and historical science topics. The main data sources include classroom observations and teacher interviews. The arguments were analyzed using Toulmin's argumentation pattern revealing specific patterns of arguments in teaching topics relying on these 2 modes of scientific inquiry. The teachers presented arguments to their students that were rather simple in structure but relatively authentic to the 2 different modes. The teachers used far more evidence in teaching topics based on historical inquiry than topics based on experimental inquiry. However, the differences were implicit in their teaching. Furthermore, their arguments did not portray the dynamic nature of science. Very few rebuttals or qualifiers were provided as the teachers were presenting their claims as if the data led straightforward to the claim. Implications for classroom practice and research are discussed.

Particle Physics in High School: A Diagnose Study

Solbes, Jordi

2016-01-01

The science learning process improves when the contents are connected to students’ lives. Particle physics has had a great impact in our society in the last years and has changed the theoretical picture about matter fundamental dynamics. Thus, we think that academic contents about matter components and interactions should be updated. With this study we aim to characterize the level of knowledge of high school students about this topic. We built a test with questions about classical atomic models, particle physics, recent discoveries, social implications and students opinions about it. Contrary to our first suspicion, students’ answers show a high variability. They have new physics ideas and show a great interest towards modern concepts. We suggest including an updated view of this topic as part of the curriculum. PMID:27253377

Highlights of aeroacoustics research in the United States of America during 1998 are reported in a summary compiled from information provided by members of the Aeroacoustics Technical Committee of the American Institute of Aeronautics and Astronautics (AIAA) and other leading research groups in industry, national laboratories, and academia. The past few years have seen significant progress in aeroacoustics. Research has steadily progressed toward enhanced safety, noise benefits, and lower costs. Since industrial progress is generally not published in the archival literature, it is particularly important to highlight these accomplishments. This year we chose to report on five topics of great interest to the aerospace industry including a synopsis of fundamental research at universities and national laboratories. The topics chosen are: (1) Advanced Subsonic Technology (AST), (2) High Speed Research (HSR), (3) Rotorcraft, (4) Weapons bay aeroacoustics control and (5) Academic research including Computational AeroAcoustics (CAA). Although the information presented in this review is not all encompassing we hope that the topics covered will provide some insights into aeroacoustics activity in the U.S.

The effectiveness of the bone bridge transtibial amputation technique: A systematic review of high-quality evidence.

2017-06-01

This literature review was undertaken to determine if commonly held views about the benefits of a bone bridge technique are supported by the literature. Four databases were searched for articles pertaining to surgical strategies specific to a bone bridge technique of the transtibial amputee. A total of 35 articles were identified as potential articles. Authors included methodology that was applied to separate topics. Following identification, articles were excluded if they were determined to be low quality evidence or not pertinent. Nine articles were identified to be pertinent to one of the topics: Perioperative Care, Acute Care, Subjective Analysis and Function. Two articles sorted into multiple topics. Two articles were sorted into the Perioperative Care topic, 4 articles sorted into the Acute Care topic, 2 articles into the Subjective Analysis topic and 5 articles into the Function topic. There are no high quality (level one or two) clinical trials reporting comparisons of the bone bridge technique to traditional methods. There is limited evidence supporting the clinical outcomes of the bone bridge technique. There is no agreement supporting or discouraging the perioperative and acute care aspects of the bone bridge technique. There is no evidence defining an interventional comparison of the bone bridge technique. Current level III evidence supports a bone bridge technique as an equivalent option to the non-bone bridge transtibial amputation technique. Formal level I and II clinical trials will need to be considered in the future to guide clinical practice. Clinical relevance Clinical Practice Guidelines are evidence based. This systematic literature review identifies the highest quality evidence to date which reports a consensus of outcomes agreeing bone bridge is as safe and effective as alternatives. The clinical relevance is understanding bone bridge could additionally provide a mechanistic advantage for the transtibial amputee.

Computational Psychotherapy Research: Scaling up the evaluation of patient-provider interactions

PubMed Central

Imel, Zac E.; Steyvers, Mark; Atkins, David C.

2014-01-01

In psychotherapy, the patient-provider interaction contains the treatment’s active ingredients. However, the technology for analyzing the content of this interaction has not fundamentally changed in decades, limiting both the scale and specificity of psychotherapy research. New methods are required in order to “scale up” to larger evaluation tasks and “drill down” into the raw linguistic data of patient-therapist interactions. In the current paper we demonstrate the utility of statistical text analysis models called topic models for discovering the underlying linguistic structure in psychotherapy. Topic models identify semantic themes (or topics) in a collection of documents (here, transcripts). We used topic models to summarize and visualize 1,553 psychotherapy and drug therapy (i.e., medication management) transcripts. Results showed that topic models identified clinically relevant content, including affective, content, and intervention related topics. In addition, topic models learned to identify specific types of therapist statements associated with treatment related codes (e.g., different treatment approaches, patient-therapist discussions about the therapeutic relationship). Visualizations of semantic similarity across sessions indicate that topic models identify content that discriminates between broad classes of therapy (e.g., cognitive behavioral therapy vs. psychodynamic therapy). Finally, predictive modeling demonstrated that topic model derived features can classify therapy type with a high degree of accuracy. Computational psychotherapy research has the potential to scale up the study of psychotherapy to thousands of sessions at a time, and we conclude by discussing the implications of computational methods such as topic models for the future of psychotherapy research and practice.

Teaching Controversial Topics to Skeptical High School Students

NASA Astrophysics Data System (ADS)

Ford, K. S.

2012-12-01

Tennessee passes the "Monkey Bill" (HB 0368, SB 0893), North Carolina's state government passes a law to criminalize reference in state documents to scientific models that predict sea level rise to reach at least one meter by the next century, and public concern still lags far behind the scientific community's concern on climate change. The American public and even science teachers across the country seem to have lost faith in the ability of the scientific community to unify a strong message about several important scientific lessons, including global warming in particular. This lack of a unified message has weakened the ability of science teachers to effectively teach the lesson of global warming. For science teachers in strongly conservative areas of the country, it is much easier to omit difficult topics and avoid angering parents and school board members. Teachers who do feel strongly about scientifically proven, yet publically controversial topics CAN teach these topics in conservative areas by confirming students' belief systems by being honest and open about motivations surrounding both sides of controversial topics, and by using vocabulary that avoids triggering negative perceptions about these controversial topics. For true learning and change of preconceived opinion to take place, it is important for students to come to the understanding in their own minds in an open and safe learning environment instead of having the message "preached" to them, which only serves to make them feel unintelligent and defensive if they disagree. This presentation will include lessons learned from a practicing science teacher who works in a community that overwhelmingly disputes the validity of human impacts on climate change.

Trends in Type of Original Psoriasis Publications by Decade, 1960 to 2010.

2016-01-01

Research investigating psoriasis has spanned decades, and as our understanding of the disease has evolved, the focus of publications has changed. We sought to characterize the trends in original psoriasis-related research from 1960 to 2010 chronologically by decade. A literature review was performed using the keyword psoriasis in the MEDLINE database. All original psoriasis-related articles published at the beginning of each decade were searched and categorized by study type and topic. Number of articles per topic. A total of 869 original psoriasis-related articles were found. The number of publications increased 18 fold over 5 decades. The immunology and pathogenesis of psoriasis was the most frequently researched topic (36%), and retrospective studies were the most common study type (37%). Recent highly published topics included biologic therapy, genetics, and psoriasis-associated cardiovascular disease. Original psoriasis-related publications have grown substantially since 1960. Basic science research into the immunology and pathogenesis has been and continues to be the mainstay of psoriasis research. Recent research trends suggest the focus has expanded to topics such as psoriasis-associated cardiovascular disease, genetics, and biologic therapy.

2015-07-15

An empiric perspective on what epidemiology has studied over time might inform discussions about future directions for the discipline. We aimed to identify the main areas of epidemiologic inquiry and determine how they evolved over time in 5 high-impact epidemiologic journals. We analyzed the titles and abstracts of 20,895 articles that were published between 1974 and 2013. In 5 time periods that reflected approximately equal numbers of articles, we identified the main topics by clustering terms based on co-occurrence. Infectious disease and cardiovascular disease epidemiology were the prevailing topics over the 5 periods. Cancer epidemiology was a major topic from 1974 to 2001 but disappeared thereafter. Nutritional epidemiology gained relative importance from 1974 to 2013. Environmental epidemiology appeared during 1996-2001 and continued to be important, whereas 2 clusters related to methodology and meta-analysis in genetics appeared during 2008-2013. Several areas of epidemiology, including injury or psychiatric epidemiology, did not make an appearance as major topics at any time. In an ancillary analysis of 6 high-impact general medicine journals, we found patterns of epidemiologic articles that were overall consistent with the findings in epidemiologic journals. This metaknowledge investigation allowed identification of the dominant topics in and conversely those that were absent from 5 major epidemiologic journals. We discuss implications for the field. © The Author 2015. Published by Oxford University Press on behalf of the Johns Hopkins Bloomberg School of Public Health. All rights reserved.

Topical Antimicrobials for Burn Infections – An Update

PubMed Central

Sevgi, Mert; Toklu, Ani; Vecchio, Daniela; Hamblin, Michael R

2014-01-01

The relentless rise in antibiotic resistance among pathogenic bacteria and fungi, coupled with the high susceptibility of burn wounds to infection, and the difficulty of systemically administered antibiotics to reach damaged tissue, taken together have made the development of novel topical antimicrobials for burn infections a fertile area of innovation for researchers and companies. We previously covered the existing patent literature in this area in 2010, but the notable progress made since then, has highlighted the need for an update to bring the reader up to date on recent developments. New patents in the areas of topically applied antibiotics and agents that can potentiate the action of existing antibiotics may extend their useful lifetime. Developments have also been made in biofilm-disrupting agents. Antimicrobial peptides are nature’s way for many life forms to defend themselves against attack by pathogens. Silver has long been known to be a highly active antimicrobial but new inorganic metal derivatives based on bismuth, copper and gallium have emerged. Halogens such as chlorine and iodine can be delivered by novel technologies. A variety of topically applied antimicrobials include chitosan preparations, usnic acid, ceragenins and XF porphyrins. Natural product derived antimicrobials such as tannins and essential oils have also been studied. Novel techniques to deliver reactive oxygen species and nitric oxide in situ have been developed. Light-mediated techniques include photodynamic therapy, ultraviolet irradiation, blue light, low-level laser therapy and titania photocatalysis. Passive immunotherapy employs antibodies against pathogens and their virulence factors. Finally an interesting new area uses therapeutic microorganisms such as phages, probiotic bacteria and protozoa to combat infections. PMID:24215506

Topical Therapies in Psoriasis

PubMed Central

Torsekar, R.; Gautam, Manjyot M.

2017-01-01

Topical therapy as monotherapy is useful in psoriasis patients with mild disease. Topical agents are also used as adjuvant for moderate-to-severe disease who are being concurrently treated with either ultraviolet light or systemic medications. Emollients are useful adjuncts to the treatment of psoriasis. Use of older topical agents such as anthralin and coal tar has declined over the years. However, they are cheaper and can still be used for the treatment of difficult psoriasis refractory to conventional treatment. Salicylic acid can be used in combination with other topical therapies such as topical corticosteroids (TCS) and calcineurin inhibitors for the treatment of thick limited plaques to increase the absorption of the latter into the psoriatic plaques. Low- to mid-potent TCS are used in facial/flexural psoriasis and high potent over palmoplantar/thick psoriasis lesions. The addition of noncorticosteroid treatment can also facilitate the avoidance of long-term daily TCS. Tacrolimus and pimecrolimus can be used for the treatment of facial and intertriginous psoriasis. Tazarotene is indicated for stable plaque psoriasis usually in combination with other therapies such as TCS. Vitamin D analogs alone in combination with TCS are useful in stable plaques over limbs and palmoplantar psoriasis. Topical therapies for scalp psoriasis include TCS, Vitamin D analogs, salicylic acid, coal tar, and anthralin in various formulations such as solutions, foams, and shampoos. TCS, vitamin D analogs, and tazarotene can be used in the treatment of nail psoriasis. PMID:28761838

Combined application versus topical and intravenous application of tranexamic acid following primary total hip arthroplasty: a meta-analysis.

The use of intravenous (IV) or topical tranexamic acid (TXA) in total hip arthroplasty has been proven to be effective and safe in total hip arthroplasty. However, which of these two administration routes is better has not been determined. The combined administration of TXA has been used in total knee arthroplasty with satisfactory results. We hypothesized that combined application of TXA may be the most effective way without increased rate of thrombotic events such as deep vein thrombosis (DVT) and pulmonary embolisms (PE) in patients subjected to primary total hip replacement (THA). A meta-analysis was conducted to compare the efficacy and safety of the combined use of tranexamic acid (TXA) relative to topical or intravenous (IV) use alone for treatment of primary THA. The outcomes included total blood loss, postoperative hemoglobin decline, transfusion rates, and the incidence rates of deep vein thrombosis (DVT) and pulmonary embolisms (PE). We searched electronic databases including PubMed, EMBASE, the Cochrane Library, Web of Science, the Chinese Biomedical Literature database, the CNKI database, and Wanfang Data until September 2016. The references of the included articles were also checked for additional potentially relevant studies. There were no language restrictions for the search. The data of the included studies were analyzed using RevMan 5.3 software. Seven studies met the inclusion criteria, encompassing a total of 1762 patients. Our meta-analysis demonstrated that total blood loss, postoperative hemoglobin decline, and transfusion rates were significantly lower for patients that received the combined treatment compared to patients that received either topical or intravenous administration of TXA. No statistical differences were found in the incidence of deep venous thrombosis (DVT) or pulmonary embolism (PE). The group that received the combined treatment had lower total blood loss, postoperative hemoglobin decline, and transfusion rates without an increased rate of thrombotic events (DVT or PE). The topical or intravenous use of TXA in primary THA is generally considered to be safe and effective. This meta-analysis demonstrated that combined TXA application may be superior to topical or intravenous application of TXA alone. However, larger, high-quality randomized control trials are required for greater confidence in this finding.

Using Delphi technique in a consensual curriculum for periodontics.

Fried, Hana; Leao, Anna Thereza

2007-11-01

Periodontics has experienced several important conceptual changes in the last few decades. As such, it is important to have a periodontics curriculum built upon the expertise of specialists in that discipline and reflecting those changes. The main goal of this study was to attain a consensus, through the use of the Delphi technique, on the topics that should be included in a periodontics curriculum for undergraduate dental students. A sample of periodontics lecturers from nine dental schools in two Brazilian cities was used, and a Delphi technique approach was followed to investigate sample member perceptions on the subject. Participants received four postal mail questionnaires asking them to rate and rerate eighty-nine topics for possible inclusion in the curriculum. A descriptive analysis was conducted, and topic frequencies were calculated. Topics rated as highly important for inclusion were the following: health, ailment, prevention, etiology, epidemiology, diagnosis, and treatment. The Delphi technique approach proved successful in involving periodontics lecturers in the design of a periodontics curriculum for undergraduate dental students.

Feasibility of Topical Applications of Natural High-Concentration Capsaicinoid Solutions in Patients with Peripheral Neuropathic Pain: A Retrospective Analysis

PubMed Central

Mouraux, Andre; Deumens, Ronald; Leerink, Marjolein; le Polain de Waroux, Bernard; Joëlle, Quetin-Leclercq

2016-01-01

Background. Capsaicin, one of several capsaicinoid compounds, is a potent TRPV1 agonist. Topical application at high concentration (high concentration, >1%) induces a reversible disappearance of epidermal free nerve endings and is used to treat peripheral neuropathic pain (PNP). While the benefit of low-concentration capsaicin remains controversial, the 8%-capsaicin patch (Qutenza®, 2010, Astellas, Netherlands) has shown its effectiveness. This patch is, however, costly and natural high-concentration capsaicinoid solutions may represent a cheaper alternative to pure capsaicin. Methods. In this retrospective study, 149 patients were screened, 132 were included with a diagnosis of neuropathic pain, and eighty-four were retained in the final analyses (median age: 57.5 years [IQR25–75: 44.7–67.1], male/female: 30/54) with PNP who were treated with topical applications of natural high-concentration capsaicinoid solutions (total number of applications: 137). Indications were postsurgical PNP (85.7%) and nonsurgical PNP (14.3%) (posttraumatic, HIV-related, postherpetic, and radicular PNP). Objectives. To assess the feasibility of topical applications of natural high-concentration capsaicinoid solutions for the treatment of PNP. Results. The median treated area was 250 cm2 [IQR25–75: 144–531]. The median amount of capsaicinoids was 55.1 mg [IQR25–75: 28.7–76.5] per plaster and the median concentration was 172.3 μg/cm2 [IQR25–75: 127.6–255.2]. Most patients had local adverse effects on the day of treatment, such as mild to moderate burning pain and erythema. 13.6–19.4% of the patients experienced severe pain or erythema. Following treatment, 62.5% of patients reported a lower pain intensity or a smaller pain surface, and 35% reported a sustained pain relief lasting for at least 4 weeks. Conclusion. Analgesic topical treatment with natural high-concentration capsaicinoid is feasible and may represent a low cost alternative to alleviate PNP in clinical practice. PMID:28115879

Dressings and topical agents for preventing pressure ulcers.

PubMed

Moore, Zena E H; Webster, Joan

2013-08-18

Pressure ulcers, which are localised injury to the skin, or underlying tissue or both, occur when people are unable to reposition themselves to relieve pressure on bony prominences. Pressure ulcers are often difficult to heal, painful and impact negatively on the individual's quality of life. The cost implications of pressure ulcer treatment are considerable, compounding the challenges in providing cost effective, efficient health services. Efforts to prevent the development of pressure ulcers have focused on nutritional support, pressure redistributing devices, turning regimes and the application of various topical agents and dressings designed to maintain healthy skin, relieve pressure and prevent shearing forces. Although products aimed at preventing pressure ulcers are widely used, it remains unclear which, if any, of these approaches are effective in preventing the development of pressure ulcers. To evaluate the effects of dressings and topical agents on the prevention of pressure ulcers, in people of any age without existing pressure ulcers, but considered to be at risk of developing a pressure ulcer, in any healthcare setting. In February 2013 we searched the following electronic databases to identify reports of relevant randomised clinical trials (RCTs): the Cochrane Wounds Group Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library); Database of Abstracts of Reviews of Effects (The Cochrane Library); Ovid MEDLINE; Ovid MEDLINE (In-Process & Other Non-Indexed Citations); Ovid EMBASE; and EBSCO CINAHL. We included RCTs evaluating the use of dressings, topical agents, or topical agents with dressings, compared with a different dressing, topical agent, or combined topical agent and dressing, or no intervention or standard care, with the aim of preventing the development of a pressure ulcer. We assessed trials for their appropriateness for inclusion and for their risk of bias. This was done by two review authors working independently, using pre-determined inclusion and quality criteria. Five trials (940 participants) of unclear or high risk of bias compared a topical agent with a placebo. Four of these trials randomised by individual and one by cluster. When results from the five trials were combined, the risk ratio (RR) was 0.78 (95% CI 0.47 to 1.31; P value 0.35) indicating no overall beneficial effect of the topical agents. When the cluster randomised trial was omitted from the analysis, use of topical agents reduced the pressure ulcer incidence by 36%; RR 0.64 (95% CI 0.49 to 0.83; P value 0.0008).Four trials (561 participants), all of which were of high or unclear risk of bias, showed that dressings applied over bony prominences reduced pressure ulcer incidence; RR 0.21 (95% CI 0.09 to 0.51; P value 0.0006). There is insufficient evidence from RCTs to support or refute the use of topical agents applied over bony prominences to prevent pressure ulcers. Although the incidence of pressure ulcers was reduced when dressings were used to protect the skin, results were compromised by the low quality of the included trials. These trials contained substantial risk of bias and clinical heterogeneity (variations in populations and interventions); consequently, results should be interpreted as inconclusive. Further well designed trials addressing important clinical, quality of life and economic outcomes are justified, based on the incidence of the problem and the high costs associated with pressure ulcer management.

Unifying concepts in the high school biology curriculum, one or many: An investigation of rural, suburban, and urban schools

NASA Astrophysics Data System (ADS)

Brown, Judith Ann

2000-10-01

Nine high school biology teachers from rural, suburban, and urban school settings, were interviewed about what idea, topic, or concept, if any, they use to unify their high school biology curriculum. Professional scientists and educational organizations have proposed that high school biology teachers use "biological evolution" as a unifying concept of their curriculum. Interviews, concept maps, and classroom syllabi and outlines were provided as data for these nine case studies. Each teacher was asked what topics were included in their curriculum to determine if a wide enough content was taught to warrant unification. The teachers' responses were compared to content and concepts listed in the National Science Content Standards, the Washington State Essential Academic Learning Requirements for Science, and a paper (Hurd, Bybee, Kahle, and Yager, 1980) that proposed what and how topics should be taught in the high school biology class by the year 2000. The nine teachers were asked to draw a concept map showing how these topics were interrelated and what concept, if any, "unified" them. A unifying concept is defined as a concept introduced early in the year and referred back to whenever new topics are introduced illustrating how the new topic is related to the previous ones through this unifying concept. Seven of the nine teachers did use at least one unifying concept. Two use evolution or natural selection, two use the web of life, two use the characteristics of life, and one uses scientific inquiry. The data collected in this study indicate high school teachers use these concepts such as the web of life and the characteristics of life because they believe they are easily understood by their students and less controversial than the theory of evolution. This study also presents evidence that school setting has minimal influence on what concept teachers use to unify their curriculum and that teachers have a significant amount of academic freedom to choose what they want to teach and how they want to teach it. The data suggests that teachers choose their unifying concept based on their personal beliefs of what their students will accept and on their past interactions with parents, students, and administrators when various unifying concepts were used.

Effects of applying anchovy (Stolephorus insularis) substrates on the microhardness of tooth enamel in Sprague-Dawley rats

NASA Astrophysics Data System (ADS)

Hendrik, Y. C.; Puspitawati, R.; Gunawan, H. A.

2017-08-01

Anchovies (Stolephorus insularis) contain high levels of fluor in the form of CaF2. The aim of this study is to analyze changes in tooth enamel microhardness after application of anchovy substrates by feeding or as a topical fluoridation material. An in vivo study of the lower left incisors of nine Sprague-Dawley rats was conducted. The sample was comprised of baseline and treatment groups, including feeding application, topical application, negative control feeding, and negative control topical groups. The treatment groups were given 5% anchovy substrates through feeding and topical applications. After treatment, tooth samples were extracted from each of the rats for examination, and statistical analyses were performed after determining hardness numbers for enamel surfaces using Vickers microhardness tester. Vickers hardness numbers (VHNs) for anchovy substrate application and consumption by feeding (440.3 ± 24.72) were higher than for the negative control (315.80 ± 17.51). VHNs for the topical application group were higher than for the negative control (347.28 ± 28.56) and for the feeding group. The use of anchovy as a fluoridation material in form of topical application is potentially an effective method for increasing the microhardness of the tooth enamel surface

Topical Botanical Agents for the Treatment of Psoriasis: A Systematic Review.

PubMed

Farahnik, Benjamin; Sharma, Divya; Alban, Joseph; Sivamani, Raja K

2017-08-01

Patients with psoriasis often enquire about the use of numerous botanical therapeutics. It is important for dermatologists to be aware of the current evidence regarding these agents. We conducted a systematic literature search using the PubMed, MEDLINE, and EMBASE databases for controlled and uncontrolled clinical trials that assessed the use of topical botanical therapeutics for psoriasis. The search included the following keywords: 'psoriasis' and 'plant' or 'herbal' or 'botanical'. We also reviewed citations within articles to identify additional relevant sources. We then further refined the results by route of administration and the topical botanical agents are reviewed herein. A total of 27 controlled and uncontrolled clinical trials addressing the use of topical botanical agents for psoriasis were assessed in this review. We found that the most highly studied and most efficacious topical botanical therapeutics were Mahonia aquifolium, indigo naturalis, aloe vera, and, to a lesser degree, capsaicin. The most commonly reported adverse effects were local skin irritation, erythema, pruritus, burning, and pain. However, the overall evidence for these therapeutics remains limited in quantity and quality. The literature addresses a large number of studies in regard to botanicals for the treatment of psoriasis. While most agents appear to be safe, further research is necessary before topical botanical agents can be consistently recommended to patients.

Using pedagogical discipline representations (PDRs) to enable Astro 101 students to reason about modern astrophysics

NASA Astrophysics Data System (ADS)

Wallace, Colin Scott; Prather, Edward E.; Chambers, Timothy G.; Kamenetzky, Julia R.; Hornstein, Seth D.

2017-01-01

Instructors of introductory, college-level, general education astronomy (Astro 101) often want to include topics from the cutting-edge of modern astrophysics in their course. Unfortunately, the teaching of these cutting-edge topics is typically confined to advanced undergraduate or graduate classes, using representations (graphical, mathematical, etc.) that are inaccessible to the vast majority of Astro 101 students. Consequently, many Astro 101 instructors feel that they have no choice but to cover these modern topics at a superficial level. Pedagogical discipline representations (PDRs) are one solution to this problem. Pedagogical discipline representations are representations that are explicitly designed to enhance the teaching and learning of a topic, even though these representations may not typically be found in traditional textbooks or used by experts in the discipline who are engaged in topic-specific discourse. In some cases, PDRs are significantly simplified or altered versions of typical discipline representations (graphs, data tables, etc.); in others they may be novel and highly contextualized representations with unique features that purposefully engage novice learners’ pre-existing mental models and reasoning difficulties, facilitating critical discourse. In this talk, I will discuss important lessons that my colleagues and I have learned while developing PDRs and describe how PDRs can enable students to reason about complex modern astrophysical topics.

In recent years, colloidal delivery systems based on nano-emulsion are gaining popularity; being used for encapsulation and delivery of many drugs. This review therefore aims at summarizing various methods of nano-emulsion formulation and their use as a topical and transdermal delivery vehicle for a number of active pharmaceutical ingredients from different pharmacological classes. This article represents a systematic review of nano-emulsions for topical and transdermal drug delivery. A vast literature was searched and critically analysed. Nano-emulsions are thermokinetically stable dispersion systems, which have been used in topical and transdermal delivery of a number of pharmaceutically active compounds. Nano-emulsions have a narrow droplet size range with tuneable surface properties, which make them an ideal delivery vehicle. Nanoemulsions have a number of advantages over conventional emulsions, including easy preparation using various low and high energy methods, optical transparency, high solubilisation capacity, high stability to droplet aggregation and the ability to penetrate the skin; thus allowing the transdermal delivery of drugs. This review indicated that nano-emulsions are promising vehicle for entrapping various drugs and are suitable for traversing the skin barrier for systemic effects.

Yao, Xiaomei; Vella, Emily

2017-09-01

As health research methodologists and journal reviewers, we noticed that the methodological rigor of many publications on diagnostic or prognostic topics in the medical literature could be improved. We present a concise and clear series of reviews to help clinicians and health researchers to master the basic key components of how to conduct a high-quality original study or systematic review on a diagnostic or prognostic research topic from a methodological perspective. This is the first review of the series, which focuses on how to conduct a high-quality diagnostic study. We are introducing four aspects: clarifying the objectives; generating an appropriate research question; planning the study design; and reporting and analyzing data. This review highlights that diagnostic test accuracy outcomes are surrogates for patient outcomes, a diagnostic test has three roles, the "PIRO" components should be included in a diagnostic research question, a new study should be registered, multiple index tests can be compared in one study, and prevalence affects test accuracy outcomes. This review also emphasizes reporting any thresholds, calculating sample size, and performing a two-by-three table to calculate diagnostic outcomes. Copyright © 2017 Elsevier Ltd.

10 Years of Student Questions about the Radiation Belts

NASA Astrophysics Data System (ADS)

Gross, N. A.; Hughes, W. J.; Wiltberger, M. J.

2016-12-01

The NSF funded CISM Space Weather Summer School is targeted to graduate students just starting in space physics and provides a comprehensive conceptual background to the field. Insights from this summer school can provide valuable information to graduate instructors and graduate student mentors. During the school, students are invited to submit questions at the end of the lecture component each day. The lecturers then take the time to respond to these questions. We have collected over 3000 student questions over the last 10 years. The radiation belts, solar energetic particles, and the operational impacts of high energy particles are among the topics covered during the summer school, and these topics consistently generate a share of the questions following those lectures. The collection includes questions about: the structure and variability of the radiation belts, the distinction between solar energetic particles (SEPs) and the radiation belts, the distinction between the ring current and the radiation belts, the impact radiation belt particles and SEPs have on the magnetosphere, the risks high energy particles pose to spacecraft and humans, their impact on operations, regulations for human exposure, and others. The presentation will catalog the questions asked by students and provide insight into students prior conceptions and misunderstandings about this topic. We hope this work informs instructors who teach these topics.

Topical Vasodilators in Microsurgery: What Is the Evidence?

PubMed

Rinkinen, Jacob; Halvorson, Eric G

2017-01-01

Background  Topical vasodilators are frequently used during free tissue transfer to prevent and treat vasospasm and microvascular thrombosis. A variety of agents have been studied and are available, yet most microsurgeons select an agent based on anecdotal evidence or personal training. Our aim was to review the literature on topical vasodilators so microsurgeons can make more informed decisions about which agent to use. Methods  A systemic review of the literature was performed on PubMed, EMBASE, and Google Scholar using keywords "topical vasodilator," "antispasmodic," "vasospasm," "free flaps," and "microsurgery." Studies were included if they provided a comparative quantitative assessment of topical vasodilators and were written in English. In vitro, in vivo , and clinical studies were included. Results  A total of 15 studies were identified and included in our analysis. The three most common classes of topical vasodilator include local anesthetics, phosphodiesterase inhibitors, and calcium channel blockers (CCBs). Of the most commonly used topical vasodilators, CCBs (nifedipine and verapamil) were most effective followed by papaverine and lidocaine. Conclusion  The most effective topical vasodilators appear to be CCBs including nifedipine, nicardipine, and verapamil. Evidence suggests that these agents are more effective than papaverine and lidocaine solutions that are commonly used. Future research should directly compare individual CCBs to assess the most effective agent. Studies to date have focused on vessels other than those used by microsurgeons, and therefore further studies specific to these vessels are warranted.

The preoperative education, which occurs in preoperative patient consultations, is an important part of the surgical nurse's profession. These consultations may be the building blocks of a partnership that facilitates communication between patient and nurse. The aim of the study was to describe topics and structure and documentation in preoperative nursing consultations with patients undergoing surgery for colorectal cancer. The study was based on analysis of consultations between seven patients and nurses at a Swedish university hospital. The preplanned preoperative consultations were audio-recorded and transcribed verbatim. The structure of the consultations was described in terms of phases and the text was analysed according to a manifest content analysis RESULTS: The consultations were structured on an agenda that was used variously and communicating different topics in an equally varied manner. Seven main topics were found: Health status, Preparation before surgery, Discovery, Tumour, Operation, Symptoms and Recovery after surgery. The topic structure disclosed a high number of subtopics. The main topics 'Discovery', 'Tumour' and 'Symptoms' were only raised by patients and occupied only 11% of the discursive space. Documentation was sparse and included mainly task-oriented procedures rather than patients' worries and concerns. There was no clear structure regarding preoperative consultation purpose and content. Using closed questions instead of open is a hindrance of developing a dialogue and thus patient participation. Preoperative consultation practice needs to be strengthened to include explicit communication of the consultations' purpose and agenda, with nurses actively discussing and responding to patients' concerns and sensitive issues. The results of the study facilitate the development of methods and structure to support person-centred communication where the patient is given space to get help with the difficult issues he/she may have when undergoing surgery. © 2016 Nordic College of Caring Science.

Summary Background Topical beta-blockers have a well-established role in the treatment of glaucoma. We aimed to investigate the outcome of patients who developed symptomatic atrioventricular (AV) block induced by topical beta-blockers. Methods All patients admitted or discharged from our institution, the Siyami Ersek Training and Research Hospital, between January 2009 and January 2013 with a diagnosis of AV block were included in the study. Subjects using ophthalmic beta-blockers were recruited and followed for permanent pacemaker requirement during hospitalisation and for three months after discontinuation of the drug. A permanent pacemaker was implanted in patients in whom AV block persisted beyond 72 hours or recurred during the follow-up period. Results A total of 1 122 patients were hospitalised with a diagnosis of AV block and a permanent pacemaker was implanted in 946 cases (84.3%) during the study period. Thirteen patients using ophthalmic beta-blockers for the treatment of glaucoma and no other rate-limiting drugs were included in the study. On electrocardiography, eight patients had complete AV block and five had high-degree AV block. The ophthalmic beta-blockers used were timolol in seven patients (55%), betaxolol in four (30%), and cartelol in two cases (15%). The mean duration of ophthalmic beta-blocker treatment was 30.1 ± 15.9 months. After drug discontinuation, in 10 patients the block persisted and a permanent pacemaker was implanted. During follow up, one more patient required pacemaker implantation. Therefore in total, pacemakers were implanted in 11 out of 13 patients (84.6%). The pacemaker implantation rate did not differ according to the type of topical beta-blocker used (p = 0.37). The presence of infra-nodal block on electrocardiography was associated with higher rates of pacemaker implantation. Conclusion Our results indicate that topical beta-blockers for the treatment of glaucoma may cause severe conduction abnormalities and when AV block occurs, pacemaker implantation is required in a high percentage of the patients.

Topical antimicrobial agents for treating foot ulcers in people with diabetes.

PubMed

Dumville, Jo C; Lipsky, Benjamin A; Hoey, Christopher; Cruciani, Mario; Fiscon, Marta; Xia, Jun

People with diabetes are at high risk for developing foot ulcers, which often become infected. These wounds, especially when infected, cause substantial morbidity. Wound treatments should aim to alleviate symptoms, promote healing, and avoid adverse outcomes, especially lower extremity amputation. Topical antimicrobial therapy has been used on diabetic foot ulcers, either as a treatment for clinically infected wounds, or to prevent infection in clinically uninfected wounds. To evaluate the effects of treatment with topical antimicrobial agents on: the resolution of signs and symptoms of infection; the healing of infected diabetic foot ulcers; and preventing infection and improving healing in clinically uninfected diabetic foot ulcers. We searched the Cochrane Wounds Specialised Register, CENTRAL, Ovid MEDLINE, Ovid MEDLINE (In-Process & Other Non-Indexed Citations), Ovid Embase, and EBSCO CINAHL Plus in August 2016. We also searched clinical trials registries for ongoing and unpublished studies, and checked reference lists to identify additional studies. We used no restrictions with respect to language, date of publication, or study setting. We included randomised controlled trials conducted in any setting (inpatient or outpatient) that evaluated topical treatment with any type of solid or liquid (e.g., cream, gel, ointment) antimicrobial agent, including antiseptics, antibiotics, and antimicrobial dressings, in people with diabetes mellitus who were diagnosed with an ulcer or open wound of the foot, whether clinically infected or uninfected. Two review authors independently performed study selection, 'Risk of bias' assessment, and data extraction. Initial disagreements were resolved by discussion, or by including a third review author when necessary. We found 22 trials that met our inclusion criteria with a total of over 2310 participants (one study did not report number of participants). The included studies mostly had small numbers of participants (from 4 to 317) and relatively short follow-up periods (4 to 24 weeks). At baseline, six trials included only people with ulcers that were clinically infected; one trial included people with both infected and uninfected ulcers; two trials included people with non-infected ulcers; and the remaining 13 studies did not report infection status.Included studies employed various topical antimicrobial treatments, including antimicrobial dressings (e.g. silver, iodides), super-oxidised aqueous solutions, zinc hyaluronate, silver sulphadiazine, tretinoin, pexiganan cream, and chloramine. We performed the following five comparisons based on the included studies: Antimicrobial dressings compared with non-antimicrobial dressings: Pooled data from five trials with a total of 945 participants suggest (based on the average treatment effect from a random-effects model) that more wounds may heal when treated with an antimicrobial dressing than with a non-antimicrobial dressing: risk ratio (RR) 1.28, 95% confidence interval (CI) 1.12 to 1.45. These results correspond to an additional 119 healing events in the antimicrobial-dressing arm per 1000 participants (95% CI 51 to 191 more). We consider this low-certainty evidence (downgraded twice due to risk of bias). The evidence on adverse events or other outcomes was uncertain (very low-certainty evidence, frequently downgraded due to risk of bias and imprecision). Antimicrobial topical treatments (non dressings) compared with non-antimicrobial topical treatments (non dressings): There were four trials with a total of 132 participants in this comparison that contributed variously to the estimates of outcome data. Evidence was generally of low or very low certainty, and the 95% CIs spanned benefit and harm: proportion of wounds healed RR 2.82 (95% CI 0.56 to 14.23; 112 participants; 3 trials; very low-certainty evidence); achieving resolution of infection RR 1.16 (95% CI 0.54 to 2.51; 40 participants; 1 trial; low-certainty evidence); undergoing surgical resection RR 1.67 (95% CI 0.47 to 5.90; 40 participants; 1 trial; low-certainty evidence); and sustaining an adverse event (no events in either arm; 81 participants; 2 trials; very low-certainty evidence). Comparison of different topical antimicrobial treatments: We included eight studies with a total of 250 participants, but all of the comparisons were different and no data could be appropriately pooled. Reported outcome data were limited and we are uncertain about the relative effects of antimicrobial topical agents for each of our review outcomes for this comparison, that is wound healing, resolution of infection, surgical resection, and adverse events (all very low-certainty evidence). Topical antimicrobials compared with systemic antibiotics : We included four studies with a total of 937 participants. These studies reported no wound-healing data, and the evidence was uncertain for the relative effects on resolution of infection in infected ulcers and surgical resection (very low certainty). On average, there is probably little difference in the risk of adverse events between the compared topical antimicrobial and systemic antibiotics treatments: RR 0.91 (95% CI 0.78 to 1.06; moderate-certainty evidence - downgraded once for inconsistency). Topical antimicrobial agents compared with growth factor: We included one study with 40 participants. The only review-relevant outcome reported was number of ulcers healed, and these data were uncertain (very low-certainty evidence). The randomised controlled trial data on the effectiveness and safety of topical antimicrobial treatments for diabetic foot ulcers is limited by the availability of relatively few, mostly small, and often poorly designed trials. Based on our systematic review and analysis of the literature, we suggest that: 1) use of an antimicrobial dressing instead of a non-antimicrobial dressing may increase the number of diabetic foot ulcers healed over a medium-term follow-up period (low-certainty evidence); and 2) there is probably little difference in the risk of adverse events related to treatment between systemic antibiotics and topical antimicrobial treatments based on the available studies (moderate-certainty evidence). For each of the other outcomes we examined there were either no reported data or the available data left us uncertain as to whether or not there were any differences between the compared treatments. Given the high, and increasing, frequency of diabetic foot wounds, we encourage investigators to undertake properly designed randomised controlled trials in this area to evaluate the effects of topical antimicrobial treatments for both the prevention and the treatment of infection in these wounds and ultimately the effects on wound healing.

Tretinoin (TRE) or all-trans retinoic acid is employed in the topical treatment of various skin diseases including acne and psoriasis. However, its use is strongly limited by side effects and high chemical instability. TRE encapsulation in nanostructured systems reduces these problems. Chitosan is a biopolymer that exhibits a number of interesting properties such as bioadhesion and antibacterial activity. The aim of this work was to prepare and characterize solid lipid nanoparticles (SLN) containing TRE, with and without addition of chitosan, to assess their in vitro cytotoxicity in keratinocytes and to evaluate their antibacterial activity against bacteria related to acne. SLN without (SLN-TRE) and with (SLN-chitosan-TRE) chitosan were prepared by hot high pressure homogenization. The hydrodynamic mean diameter and zeta potential were 162.7±1.4 nm and -31.9±2.0 mV for SLN-TRE, and 284.8±15.0 nm and 55.9±3.1 mV for SLN-chitosan-TRE. The SLN-chitosan-TRE exhibited high encapsulation efficiency, high physical stability in the tested period (one year), were not cytotoxic to keratinocytes and showed high antibacterial activity against P. acnes and S. aureus. Therefore chitosan-SLN can be good candidates to encapsulate TRE and to increase its therapeutic efficacy in the topical treatment of acne. Copyright © 2011 Elsevier B.V. All rights reserved.

The analysis focused on how arguments constructed by teachers differed based on the mode of inquiry underlying the topic. Specifically, how did the structure and content of arguments differ between experimentally and historically based topics? In addition, what factors mediate these differences? Four highly experienced high school science teachers were observed daily during instructional units for both experimental and historical science topics. Data sources include classroom observations, field notes, reflective memos, classroom artifacts, a nature of science survey, and teacher interviews. The arguments were analyzed for structure and content using Toulmin's argumentation pattern and Walton's schemes for presumptive reasoning revealing specific patterns of use between the two modes of inquiry. Interview data was analyzed to determine possible factors mediating these patterns. The results of this study reveal that highly experienced teachers present arguments to their students that, while simple in structure, reveal authentic images of science based on experimental and historical modes of inquiry. Structural analysis of the data revealed a common trend toward a greater amount of scientific data used to evidence knowledge claims in the historical science units. The presumptive reasoning analysis revealed that, while some presumptive reasoning schemes remained stable across the two units (e.g. 'causal inferences' and 'sign' schemes), others revealed different patterns of use including the 'analogy', 'evidence to hypothesis', 'example', and 'expert opinion' schemes. Finally, examination of the interview and survey data revealed five specific factors mediating the arguments constructed by the teachers: view of the nature of science, nature of the topic, teacher personal factors, view of students, and pedagogical decisions. These factors influenced both the structure and use of presumptive reasoning in the arguments. The results have implications for classroom practice, teacher education, and further research.

Patients with psoriasis have to cope with their disease for many years or even throughout their entire life. To provide optimal care, a disease management programme was developed. This programme consisted of disease education, disease management training, and psychological support, together with topical treatment. To test a disease management programme in dermatological practice, to assess patients' satisfaction with this programme, and adherence to topical treatment. Additionally, disease severity and quality of life were assessed. An initial clinical investigation was conducted in 10 European treatment centres. A total of 330 patients were included. Patient satisfaction, adherence, disease severity and quality of life were measured with study-specific and standardized self-report questionnaires. Patients reported a high degree of satisfaction with the programme, and a high degree of adherence to topical treatment. Disease severity and quality of life significantly improved. The programme was well received by the participating professionals. The disease management programme was found to be a useful tool in the management of psoriasis, providing patients with relief from the burden of psoriasis in everyday life. A full-scale evaluation is recommended.

Other topics include a discussion of modern relativistic cosmology, the consequences of Hubble's observations leading to the Big Bang hypothesis, and an overview of the most exciting research topics in relativistic cosmology. This textbook is intended for introductory undergraduate courses on the foundations of modern physics. It is also accessible to advanced high school students, as well as non-science majors who are concerned with science issues.• Uses a historical perspective to describe the evolution of modern ideas about space and time • The main arguments are described using a completely non-mathematical approach • Ideal for physics undergraduates and high-school students, non-science majors and general readers

Topical oxygen as an adjunct to wound healing: a clinical case series.

PubMed

Kalliainen, Loree K.; Gordillo, Gayle M.; Schlanger, Richard; Sen, Chandan K.

2003-01-01

BACKGROUND: Disrupted vasculature and high energy-demand to support processing and regeneration of wounded tissue are typical characteristics of a wound site. Oxygen delivery is a critical element for the healing of wounds. Clinical experience with adjunctive hyperbaric oxygen therapy in the treatment of chronic wounds have shown that wound hyperoxia increases wound granulation tissue formation and accelerates wound contraction and secondary closure. Nevertheless, the physiologic basis for this modality remains largely unknown. Also, systemic hyperbaric oxygen therapy is associated with risks related to oxygen toxicity. Topical oxygen therapy represents a less explored modality in wound care. The advantages of topical oxygen therapy include low cost, lack of systemic oxygen toxicity, and the ability to receive treatment at home, making the benefits of oxygen therapy available to a much larger population of patients. MATERIALS AND METHODS: Over 9 months, seven surgeons treated 58 wounds in 32 patients with topical oxygen with follow-up ranging from 1 to 8 months. The data presented herein is a retrospective analysis of the results we have achieved using topical oxygen on complex wounds. RESULTS: Thirty-eight wounds in 15 patients healed while on topical oxygen. An additional five wounds in five patients had preoperative oxygen therapy; all wounds initially healed postoperatively. In two patients, wounds recurred post-healing. In ten wounds, topical oxygen had no effect; and two of those patients went on to require limb amputation. There were no complications attributable to topical oxygen. Three patients died during therapy and one died in the first postoperative month from underlying medical problems. Two patients were lost to follow-up. CONCLUSIONS: In this case series, topical oxygen had no detrimental effects on wounds and showed beneficial indications in promoting wound healing.

Comparable efficacy and safety of various topical formulations of terbinafine in tinea pedis irrespective of the treatment regimen: results of a meta-analysis.

PubMed

Korting, Hans Christian; Kiencke, Peter; Nelles, Sandra; Rychlik, Reinhard

2007-01-01

Terbinafine has been widely used with major success as a topical antifungal therapy for tinea pedis (athlete's foot). Its efficacy and safety have been validated in several clinical trials, which have demonstrated clinical efficacy for the drug after only 1 week of treatment when applied once daily, a reflection of the high fungicidal potency of the drug and its ability to form a depot in the upper skin layer. To improve patients' compliance further, a terbinafine-containing film-forming solution has been developed for single-dose therapy of athlete's foot. This novel formulation delivers terbinafine in high amounts and for a prolonged period of time into the skin, making one-shot treatment feasible. Over the past years there have been a variety of trials evaluating use of topical terbinafine addressing different pharmaceutical formulations, treatment durations, and application frequencies, but a detailed meta-analysis of these trials has not been conducted to date. The present study is the first meta-analytic evaluation of the available data on the efficacy (clinical and mycologic cure rates) and safety (adverse events) of all topical forms of terbinafine for the treatment of tinea pedis. An international, systematic literature search of 12 electronic databases (including MEDLINE, EMBASE, and Cochrane databases) using a pre-specified search strategy was conducted in March 2006. This meta-analysis included only randomized controlled trials in which terbinafine had been used for topical treatment of tinea pedis in comparison with placebo or an active control. Studies of all available topical formulations of terbinafine, frequencies of application, and durations of treatment were included. Of 100 identified articles published between 1990 and 2006, 19 met the criteria for analysis. These 19 studies involved 2899 patients with clinical and mycologic diagnoses of tinea pedis (nine placebo-controlled trials and ten active-controlled trials). Efficacy analysis demonstrated that the mycologic cure rate was significantly superior with terbinafine compared with placebo (relative risk [RR] 3.17; p < 0.001). No significant differences in efficacy were found amongst different formulations of terbinafine, treatment durations, or frequencies of application. Comparable results were obtained with respect to clinical cure rate for terbinafine compared with placebo (RR 2.75; p < 0.001). Comparison of the efficacy of terbinafine versus active control indicated a nonsignificant difference in favor of terbinafine with regard to mycologic cure rate (RR 1.03; p = 0.423) and clinical cure rate (RR 1.09; p = 0.11). The median duration of treatment was also shorter with terbinafine (1 week) compared with active controls (2 weeks). Analysis of the placebo-controlled studies showed that there was no significant difference in the risk of adverse events with terbinafine compared with placebo (RR 1.34; p = 0.34). Likewise, no significant differences in adverse events were found between terbinafine and active controls (RR 1.08; p = 0.72). Terbinafine is very well tolerated in any topical pharmaceutical formulation and also has high efficacy as a cure for tinea pedis, irrespective of type of pharmaceutical formulation, treatment duration, and frequency of application, including the recently established one-shot regimen. In addition, terbinafine has an apparently unique advantage over other antifungal agents with respect to the required duration of treatment for tinea pedis.

Topical treatment and combination approaches for vitiligo: new insights, new developments.

PubMed

Hossani-Madani, A R; Halder, R M

2010-02-01

Despite much research done involving elucidation of the pathogenesis of vitiligo, a precise cause is still not known. Prevalent hypotheses include the autoimmune, genetic, neural, self-destruction, growth factor deficiency, viral, and convergence theories, which have served as the basis for treatment formulation. Topical therapies have been a mainstay of vitiligo treatment, with or without phototherapy. Topical treatments used in the treatment of vitiligo include steroids, calcineurin inhibitors, vitamin D analogues, pseudocatalase, and depigmenting agents. Combination therapies are used to improve the success rate of repigmentation. In this article, we have examined randomized controlled trials utilizing topical treatments used as monotherapy or combination therapy. Although psoralen and khellin can be used as topical agents, used in conjunction with UV radiation, we have not included them in the review due to their inability to be used as monotherapy. We have also excluded less used or ineffective topical agents, such as melagenina, topical phenylalanine, topical L-DOPA, coal tar, anacarcin forte oil and topical minoxidil. According to current guidelines, a less than two month trial of potent or very potent topical corticosteroids or topical calcineurin inhibitors may be used for therapy of localized vitiligo (<20% skin surface area). Combinations of topical corticosteroids with excimer laser and UVA seem to be more effective than steroids alone. Pseudocatalase plus NB-UVB does not seem to be more effective than placebo with NB-UVB. Combinations of vitamin D analogues have varied efficacy based on which type is used and the type of UV light. Efficacy of calcineurin inhibitor combinations also vary based on the type used and UV light combined, with tacrolimus being more effective with excimer laser. Pimecrolimus has been effective with NB-UVB and excimer laser on facial lesions, and microdermabrasion on localized areas.

Safety, efficacy, and patient acceptability of lidocaine hydrochloride ophthalmic gel as a topical ocular anesthetic for use in ophthalmic procedures

PubMed Central

Page, Michael A; Fraunfelder, Frederick W

2009-01-01

Purpose: To review the current literature on safety, efficacy, and measures of surgeon and patient satisfaction with lidocaine hydrochloride gel as a tool for ocular anesthesia. Methods: Pubmed search using keywords “lidocaine gel,” “ophthalmic,” and “surgery” and compiling cross-references. Twenty-six total references were reviewed, including 15 prospective randomized controlled trials (RCTs, total N = 933, average N = 62), 6 nonrandomized prospective studies (total N = 234, average N = 39), 2 animal studies, 1 microbiologic study, and 2 letters to the editor. Results: The RCTs and nonrandomized prospective studies evaluated a number of measures including timing of onset of anesthesia, duration of anesthesia, intraoperative and postoperative pain, need for additional anesthetic applications, intracameral lidocaine levels, and adverse effects. Control groups received topical drops, subconjunctival anesthetic, retrobulbar anesthetic, or sham gel. Lidocaine gel was shown to be at least as effective for pain control as alternative therapies in all studies, with longer duration of action than topical drops. Patient and surgeon satisfaction were high, and adverse effects were rare and comparable to those for anesthetic drop formulations. Surgical settings included cataract, pterygium, trabeculectomy, strabismus, intravitreal injection, vitrectomy, and penetrating keratoplasty. Conclusions: Lidocaine gel is a safe, effective, and potentially underutilized tool for ophthalmic surgery. PMID:19898665

Methemoglobinemia secondary to topical benzocaine use in a lung transplant patient.

LeClaire, Aimée C; Mullett, Timothy W; Jahania, M Salik; Flynn, Jeremy D

2005-02-01

To report a case of methemoglobinemia secondary to the administration of topical benzocaine spray in an anemic patient who had previously undergone a lung transplant. A 40-year-old white man with a past medical history significant for lung transplant acutely decompensated following oropharyngeal administration of topical benzocaine spray. Subsequent blood analysis revealed a methemoglobin concentration of 51.2%. Following the administration of a single dose of methylene blue 2 mg/kg intravenously, the patient's respiratory status dramatically improved and stabilized. Methemoglobinemia is a rare but potentially fatal condition that may be either acquired or congenital; however, the disorder is most commonly acquired secondary to exposure to oxidizing chemicals, which are often routinely prescribed medications, including benzocaine. Benzocaine can react with hemoglobin to form methemoglobin at a rate that exceeds reduction capabilities, which may result in oxygenation difficulty and respiratory distress. In severe or symptomatic methemoglobinemia, the treatment of choice is methylene blue. Application of the Naranjo probability scale established a highly probable relationship between topical benzocaine spray and methemoglobinemia and associated respiratory compromise. The risks of palliative use of topical benzocaine in patients with preexisting disorders that compromise oxygen delivery may outweigh any benefit. In our patient, anemia and lung disease increased his risk for clinically significant adverse respiratory events secondary to deficiencies or interferences in oxygen delivery. Topical benzocaine should be administered with caution and careful monitoring in such patient populations.

Quality and Importance of Health Policy, Reform, and Public Health Topics: A Study in Physician Assistant Education.

PubMed

Angerer-Fuenzalida, Frances M

2018-06-01

As key players in a changing US health care system, physician assistants (PAs) must be prepared to act with a clear understanding of health policy as reform changes are enacted. The purpose of this study was to assess the perceptions of graduating PA students about the importance of health policy, reform, and public health and their perception of their preparedness in these areas. The research question was: Do PA students identify these topic areas as important, and, for each topic area, do they feel adequately prepared with sufficient knowledge for clinical practice? Participants in the study included 352 PA students from 14 PA programs randomly selected from 4 geographic regions of the continental United States. A 20-item instrument, the Health Policy Perception Tool, was developed and validated for data collection. Physician assistant students rated content items high on the importance scale and displayed a wide range of ratings on their perceived preparedness in each content area. Health policy/reform items demonstrated the highest disparity, with students indicating that they were least prepared in content areas relating to the Affordable Care Act, such as patient-centered medical home and accountable care organizations. They also rated health system structure/function items as moderately important, but indicated that they were ill prepared on this topic. Public health topics were rated highly on both scales. Physician assistant programs appear to be addressing public health issues well; however, PA education leaders must address the low levels of preparedness in the other areas of health care, specifically those related to health structure/function and health reform.

Extramammary Paget's disease is a rare neoplasm of apocrine gland-bearing areas of the skin. The most common site of presentation is the vulva. Surgery is the most frequently reported therapy so far; however, it is invasive and it is complicated by a high rate of recurrence. For this reason, several less-invasive treatments have been recently proposed, including photodynamic therapy. We describe in this article the case of an 84-year-old patient with a noninvasive vulvar extramammary Paget's disease successfully treated with methyl-aminolevulinic acid photodynamic therapy associated with topical tretinoin. © 2013 Wiley Periodicals, Inc.

The increasing trend of overweight in the military, the high cost of health care associated with overweight, and the failure to meet some Healthy People 2000 objectives related to diet identify the need for more appropriate nutrition and fitness education for military personnel. The purpose of this study was to assess senior military officers' concerns on various health topics, educational preferences for nutrition and health topics, eating habits, and barriers and motivators for eating healthfully and exercising regularly. The survey was completed by 52 resident students at the U.S. Army War College. Fitness, weight, and blood cholesterol were top health concerns, and respondents wanted to know more about eating healthfully on the run. The primary barrier to eating healthfully and exercising regularly was lack of time, whereas health and appearance were top motivators. Health interventions for this population should include their topics of concern and should address perceived barriers and motivators.

Alkemio: association of chemicals with biomedical topics by text and data mining

PubMed Central

Gijón-Correas, José A.; Andrade-Navarro, Miguel A.; Fontaine, Jean F.

2014-01-01

The PubMed® database of biomedical citations allows the retrieval of scientific articles studying the function of chemicals in biology and medicine. Mining millions of available citations to search reported associations between chemicals and topics of interest would require substantial human time. We have implemented the Alkemio text mining web tool and SOAP web service to help in this task. The tool uses biomedical articles discussing chemicals (including drugs), predicts their relatedness to the query topic with a naïve Bayesian classifier and ranks all chemicals by P-values computed from random simulations. Benchmarks on seven human pathways showed good retrieval performance (areas under the receiver operating characteristic curves ranged from 73.6 to 94.5%). Comparison with existing tools to retrieve chemicals associated to eight diseases showed the higher precision and recall of Alkemio when considering the top 10 candidate chemicals. Alkemio is a high performing web tool ranking chemicals for any biomedical topics and it is free to non-commercial users. Availability: http://cbdm.mdc-berlin.de/∼medlineranker/cms/alkemio.

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

Treatment of rosacea.

A range of treatment options are available in rosacea, which include several topical (mainly metronidazole, azelaic acid, other antibiotics, sulfur, retinoids) and oral drugs (mainly tetracyclines, metronidazole, macrolides). In some cases, the first choice is a systemic therapy because patients may have sensitive skin and topical medications can be irritant. Isotretinoin can be used in resistant cases of rosacea. Unfortunately, the majority of studies on rosacea treatments are at high or unclear risk of bias. A recent Cochrane review found that only topical metronidazole, azelaic acid, and oral doxycycline (40 mg) had some evidence to support their effectiveness in moderate to severe rosacea and concluded that further well-designed, adequately-powered randomised controlled trials are required. In our practice, we evaluate our patients for the presence of two possible triggers, Helicobacter pylori infection and small intestinal bacterial overgrowth. When they are present we use adapted antibiotic protocols. If not, we use oral metronidazole or oral tetracycline to treat papulopustolar rosacea. We also look for Demodex folliculorum infestation. When Demodex concentration is higher than 5/cm(2) we use topical crotamiton 10% or metronidazole. Copyright © 2011 Elsevier Masson SAS. All rights reserved.

Schmidt, David K.

1991-01-01

Research dealt with the general area of optimal flight control synthesis for manned flight vehicles. The work was generic; no specific vehicle was the focus of study. However, the class of vehicles generally considered were those for which high authority, multivariable control systems might be considered, for the purpose of stabilization and the achievement of optimal handling characteristics. Within this scope, the topics of study included several optimal control synthesis techniques, control-theoretic modeling of the human operator in flight control tasks, and the development of possible handling qualities metrics and/or measures of merit. Basic contributions were made in all these topics, including human operator (pilot) models for multi-loop tasks, optimal output feedback flight control synthesis techniques; experimental validations of the methods developed, and fundamental modeling studies of the air-to-air tracking and flared landing tasks.

Perioperative antibiotics for prevention of acute endophthalmitis after cataract surgery

Background Endophthalmitis is a severe inflammation of the anterior or posterior (or both) chambers of the eye that may be sterile or associated with infection. It is a potentially vision-threatening complication of cataract surgery. Prophylactic measures for endophthalmitis are targeted against various sources of infection. Objectives To evaluate the effects of perioperative antibiotic prophylaxis for endophthalmitis following cataract surgery compared with no prophylaxis or other form of prophylaxis. Search methods We searched CENTRAL (which contains the Cochrane Eyes and Vision Trials Register) (2016, Issue 12), Ovid MEDLINE, Epub Ahead of Print, In-Process & Other Non-Indexed Citations, Ovid MEDLINE Daily (January 1946 to December 2016), Embase (January 1980 to December 2016), Latin American and Caribbean Health Sciences Literature Database (LILACS) (1982 to December 2016),the ISRCTN registry (www.isrctn.com/editAdvancedSearch), ClinicalTrials.gov (www.clinicaltrials.gov), and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We used no date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 6 December 2016. We also searched for additional studies that cited any included trials using the Science Citation Index. Selection criteria We included randomized controlled trials that enrolled adults undergoing cataract surgery (any method and incision type) for lens opacities due to any origin. We included trials that evaluated preoperative antibiotics, intraoperative (intracameral, subconjunctival or systemic), or postoperative antibiotic prophylaxis for acute endophthalmitis. We excluded studies that evaluated antiseptic preoperative preparations using agents such as povidone iodine or antibiotics for treating acute endophthalmitis after cataract surgery. Data collection and analysis Two review authors independently reviewed abstracts and full-text articles for eligibility, assessed the risk of bias for each included study, and abstracted data. Main results Five studies met the inclusion criteria for this review, including 101,005 adults and 132 endophthalmitis cases. While the sample size was very large, the heterogeneity of the study designs and modes of antibiotic delivery made it impossible to conduct a formal meta-analysis. Interventions investigated included the utility of adding vancomycin and gentamycin to the irrigating solution compared with standard balanced saline solution irrigation alone, use of intracameral cefuroxime with or without topical levofloxacin perioperatively, periocular penicillin injections and topical chloramphenicol-sulfadimidine drops compared with topical antibiotics alone, and mode of antibiotic delivery (subconjunctival versus retrobulbar injections; fixed versus separate instillation of gatifloxacin and prednisolone). The risk of bias among studies was low to unclear due to information not being reported. We identified one ongoing study. Two studies compared any antibiotic with no antibiotic. One study, which compared irrigation with antibiotics in balanced salt solution (BSS) versus BSS alone, was not sufficiently powered to detect differences in endophthalmitis between groups (very low-certainty evidence). One study found reduced risk of endophthalmitis when combining intracameral cefuroxime and topical levofloxacin (risk ratio (RR) 0.14, 95% confidence interval (CI) 0.03 to 0.63; 8106 participants; high-certainty evidence) or using intracameral cefuroxime alone (RR 0.21, CI 0.06 to 0.74; 8110 participants; high-certainty evidence) compared with placebo, and an uncertain effect when using topical levofloxacin alone compared with placebo (RR 0.72, CI 0.32 to 1.61; 8103 participants; moderate-certainty evidence). Two studies found reduced risk of endophthalmitis when combining antibiotic injections during surgery and topical antibiotics compared with topical antibiotics alone (risk ratio (RR) 0.33, 95% confidence interval (CI) 0.12 to 0.92 (periocular penicillin and topical chloramphenicol-sulfadimidine; 6618 participants; moderate-certainty evidence); and RR 0.20, 95% CI 0.04 to 0.91 (intracameral cefuroxime and topical levofloxacin; 8101 participants; high-certainty evidence)). One study, which compared fixed versus separate instillation of gatifloxacin and prednisolone, was not sufficiently powered to detect differences in endophthalmitis between groups (very low-certainty evidence). Another study found no evidence of a difference in endophthalmitis when comparing subconjunctival versus retrobulbar antibiotic injections (RR 0.85, 95% CI 0.55 to 1.32; 77,015 participants; moderate-certainty evidence). Two studies reported any visual acuity outcome; one study, which compared fixed versus separate instillation of gatifloxacin and prednisolone, reported only that mean visual acuity was the same for both groups at 20 days postoperation. In the other study, the difference in the proportion of eyes with final visual acuity greater than 20/40 following endophthalmitis between groups receiving intracameral cefuroxime with or without topical levofloxacin compared with no intracameral cefuroxime was uncertain (RR 0.69, 95% CI 0.22 to 2.11; 29 participants; moderate-certainty evidence). Only one study reported adverse events (1 of 129 eyes had pupillary membrane in front of the intraocular lens and 8 eyes showed posterior capsule opacity). No study reported outcomes related to quality of life or economic outcomes. Authors’ conclusions Multiple measures for preventing endophthalmitis following cataract surgery have been studied. High-certainty evidence shows that injection with cefuroxime with or without topical levofloxacin lowers the chance of endophthalmitis after surgery, and there is moderate-certainty evidence to suggest that using antibiotic eye drops in addition to antibiotic injection probably lowers the chance of endophthalmitis compared with using injections or eye drops alone. Clinical trials with rare outcomes require very large sample sizes and are quite costly to conduct; thus, it is unlikely that many additional clinical trials will be conducted to evaluate currently available prophylaxis. Practitioners should rely on current evidence to make informed decisions regarding prophylaxis choices. PMID:28192644

Topical photodynamic therapy with methylaminolevulinate for the treatment of actinic keratosis and reduction of photodamage in organ transplant recipients: a case-series of 16 patients.

Organ transplant recipients (OTR) are at high risk of developing cutaneous neoplasms. Topical photodynamic therapy (PDT) has been used for the treatment of actinic keratosis (AK) in OTR. The objective was to evaluate the efficacy of PDT with methylaminolevulinate (MAL) in the treatment of facial AK in OTR. As a secondary objective, we wanted to evaluate the usefulness of topical PDT in the reduction of photodamage in OTR. A prospective, single center, single arm study was made. 16 OTR were included. Topical PDT was applied for 1 or 2 cycles depending on the patient's characteristics. An evaluation of AK was made at visits pre-treatment, at 12 weeks and at 24 weeks. Photodamage was measured with multispectral image technique (SkinCare). A complete response rate of 100% was achieved for AK in all patients; it persisted without change at 12 and 24 weeks of follow-up. 62.5% of patients improved their photodamage as measured by SkinCare®, but this result was not statistically significant (P = 0.12). All patients had high level of satisfaction at the end of the therapy. MAL-PDT is an effective therapy for the treatment of AK in OTRs. It can reduce photodamage in this group of patients, but these results were not statistically significant.

Missing and accounted for: gaps and areas of wealth in the public health review literature

PubMed Central

2011-01-01

Background High-quality review evidence is useful for informing and influencing public health policy and practice decisions. However, certain topic areas lack representation in terms of the quantity and quality of review literature available. The objectives of this paper are to identify the quantity, as well as quality, of review-level evidence available on the effectiveness of public health interventions for public health decision makers. Methods Searches conducted on http://www.health-evidence.ca produced an inventory of public health review literature in 21 topic areas. Gaps and areas of wealth in the review literature, as well as the proportion of reviews rated methodologically strong, moderate, or weak were identified. The top 10 topic areas of interest for registered users and visitors of http://www.health-evidence.ca were extracted from user profile data and Google Analytics. Results Registered users' top three interests included: 1) healthy communities, 2) chronic diseases, and 3) nutrition. The top three preferences for visitors included: 1) chronic diseases, 2) physical activity, and 3) addiction/substance use. All of the topic areas with many (301+) available reviews were of interest to registered users and/or visitors (mental health, physical activity, addiction/substance use, adolescent health, child health, nutrition, adult health, and chronic diseases). Conversely, the majority of registered users and/or visitors did not have preference for topic areas with few (≤ 150) available reviews (food safety and inspection, dental health, environmental health) with the exception of social determinants of health and healthy communities. Across registered users' and visitors' topic areas of preference, 80.2% of the reviews were of well-done methodological quality, with 43.5% of reviews having a strong quality rating and 36.7% a moderate review quality rating. Conclusions In topic areas in which many reviews are available, higher level syntheses are needed to guide policy and practice. For other topic areas with few reviews, it is necessary to determine whether primary study evidence exists, or is needed, so that reviews can be conducted in the future. Considering that less than half of the reviews available on http://www.health-evidence.ca are of strong methodological quality, the quality of the review-level evidence needs to improve across the range of public health topic areas.

Topical hexaminolevulinate photodynamic therapy for the treatment of persistent human papilloma virus infections and cervical intraepithelial neoplasia.

Hillemanns, Peter; Einstein, Mark H; Iversen, Ole Erik

2015-02-01

Current treatments for high-grade cervical intraepithelial neoplasia (CIN2/3) are mainly excisional procedures, which are associated with significant side effects and pose risks for future pregnancies. An effective and safe therapy is needed to reduce the requirement for surgical interventions in women of reproductive age. This review looks at the pharmacokinetic and clinical data for topical hexaminolevulinate (HAL) photodynamic therapy (PDT), which is currently entering late phase clinical trials for high-grade CIN. The authors include published studies in patients and volunteers but laboratory and animal studies have been excluded as have studies on other porphyrins such as Photofrin, 5-aminolevulinic acid, methyl aminolevulinate and studies reporting other clinical applications for HAL. Topical HAL PDT has potential as a non-surgical tissue-preserving treatment for CIN and persistent oncogenic human papilloma virus infections. HAL PDT selectively treats the entire epithelial sheet, without the tissue destruction seen in excisional procedures. The authors believe that this treatment could replace surgery in a large proportion of patients. It would be of particular value to the high percentage of women who are interested in future child-bearing. If the treatment is approved, it is very likely that physicians will want to use this treatment, as many patients will be keen to consider a non-surgical option.

Topical retinoids have been in clinical use for the treatment of chronic skin conditions, including acne, photodamage, and psoriasis, for 30 years. A systematic literature review was conducted to assess the incidence of noncutaneous adverse events (AE) among patients treated with topical retinoids with a focus on topical tretinoin studies reported before the Veterans Affairs Topical Tretinoin Chemoprevention trial. Electronic literature searches were conducted in Embase and MEDLINE for literature reporting development of nonteratogenic, noncutaneous AE among patients treated with topical retinoids published through September 2008. The search yielded 2778 citations, of which 20 studies met inclusion criteria. Tretinoin was used in 14 of the studies. Other retinoids assessed included isotretinoin, adapalene, alitretinoin, and tazarotene. Within patients receiving topical tretinoin, 27.9% reported the occurrence of at least one noncutaneous AE. The majority of noncutaneous AE were transient and judged not to be related to tretinoin treatment. The conclusions of this study apply largely to tretinoin compared with other topical retinoids. Many of the included trials were designed to evaluate the efficacy of topical treatment and reporting of safety events concentrated on incidence of localized AE, rather than systemic or noncutaneous events. We found no clear evidence of a relationship between the use of topical tretinoin and the development of noncutaneous AE before a recent report of excess mortality in a clinical trial. The majority of noncutaneous AE reported by patients receiving topical retinoids consisted of nonsevere, nonspecific symptoms that were judged not to be related to treatment.

Twitter is a social media platform that can be used by people working in health and medicine to distribute information, advocate, debate and network with large numbers of other users. We set out to determine the top 10 Australian Twitter accounts in four categories, ranked by number of Twitter followers. We extracted names with high follower volumes from 'lists' of health and medical Twitter accounts, and then 'crowdsourced' on Twitter for names that were not included on those lists. Individuals tweeting on single-issue topics (especially sugar, nutrition and fitness), health institutions, and people working in the media had higher Twitter followings and lower tweet-to-follower ratios than those tweeting on mixed health topics. Tweeting pictures was nominated by several as a way of attracting retweets. Highly followed Twitter users expressed a variety of benefits of using Twitter.

The purpose of this study was to identify radiology topics considered essential by residency program directors who will be working with our graduates. Secondary goals were to survey their satisfaction with incoming residents' radiology knowledge, inquire if radiology training was provided in their programs, and identify differences among specialties. A questionnaire was mailed to all residency program directors in emergency medicine, family medicine, internal medicine, pediatrics, and general surgery programs that accepted our graduates between 2005 and 2010. Program directors were asked to rate a list of radiology knowledge and skills topics as essential or nonessential and to answer several questions regarding their residents and programs. Ninety-nine surveys were completed (51.3% response rate). Seven skills were considered essential by 90% or more of all respondents. On average, program directors identified 18/28 topics as essential prior to beginning their residency. The mean number identified as essential did not differ by program (F4, 93 = 0.732, P = .572). Based on analyses of variance comparing each topic by program, the importance of six topics differed significantly. Program directors generally agreed that incoming residents had adequate radiology skills and knowledge when they started their residencies. One hundred percent of the responding emergency medicine, family medicine, and pediatrics programs and 70% to 80% of the general surgery and internal medicine programs provide radiology training. There is high agreement among program directors regarding imaging topics they consider essential. Topics considered essential by more than 60% should comprise our core curriculum for all students while less essential topics can be included in elective or program specific curricula.

Topicality and impact in social media: diverse messages, focused messengers.

PubMed

Weng, Lilian; Menczer, Filippo

2015-01-01

We have a limited understanding of the factors that make people influential and topics popular in social media. Are users who comment on a variety of matters more likely to achieve high influence than those who stay focused? Do general subjects tend to be more popular than specific ones? Questions like these demand a way to detect the topics hidden behind messages associated with an individual or a keyword, and a gauge of similarity among these topics. Here we develop such an approach to identify clusters of similar hashtags in Twitter by detecting communities in the hashtag co-occurrence network. Then the topical diversity of a user's interests is quantified by the entropy of her hashtags across different topic clusters. A similar measure is applied to hashtags, based on co-occurring tags. We find that high topical diversity of early adopters or co-occurring tags implies high future popularity of hashtags. In contrast, low diversity helps an individual accumulate social influence. In short, diverse messages and focused messengers are more likely to gain impact.

To evaluate the efficacy of topical anesthesia; topical Benoxinate 0.4% (Oxybuprocaine) and Xylocaine (Lidocaine) gel, in selected cataract patients as an alternative to peribulbar or retrobulbar block anesthesia during cataract surgery. Prospective non-comparative evaluation of patients' and surgeon's satisfaction at the end of the procedure. Three hundred patients (300 eyes) were included in the study. The procedure was explained to patients with details regarding what will happen and what to expect during surgery. All patients received topical anesthesia with Benoxinate 0.4% eye drops and Xylocaine gel 2%. All surgeries were done by the same surgeon using the same machine (updated LEGACY phacoemulsifier, Alcon) and approach (clear corneal incision) and followed by a foldable intraocular lens (IOL) implantation. None of the patients had severe pain during the procedure; only 2% (six of 300) required use of intravenous sedation (Propofol), both the surgeon's and the patients' satisfaction were high. Eye movements and blepharospasm were not significant problems, and no serious complications occurred. Rate of vitreous loss due to posterior capsule tear/rupture was within literature reported range and not different from our previous experience. Topical anesthesia is a satisfactory and safe alternative to retrobulbar and peribulbar anesthesia for clear corneal phacoemulsification and intraocular lens implantation in selected cataract patients in the hands of experienced cataract surgeon.

To examine the effect of one standardized patient question on the length, number and type of new topics pharmacists addressed. To explore how community pharmacists counsel secret shoppers on two types of over-the-counter (OTC) medications-ibuprofen (IB) and emergency contraceptives (EC). 25 pharmacists from 7 independent, midwestern community pharmacies consented to have secret shoppers purchase an OTC medication and to have their consultations audio-recorded. Following standardized scenarios, 5 secret shoppers audio-recorded 73 encounters. At the end of 36 encounters secret shoppers asked one standard question, "What else should I know before taking this product?" Role Theory informed the study design with apriori hypotheses that topics assessed, topics discussed, and consultation length would vary by the OTC medication (IB or EC) and whether secret shoppers asked a question. Audio-recording coding had high inter-rater reliability (kappa=0.94). Length of encounter was significantly associated with patients asking the question (p<0.05), but not type of OTC medication. On average 1.22 new topics were discussed with a patient question. New topics included information about safe and efficacious use of the OTC's. Results highlight the importance of encouraging patients to ask pharmacists their questions about OTC products for safe use and thorough consultations. Copyright © 2016.

PubMed

Svendsen, Mathias Tiedemann; Andersen, Flemming; Andersen, Klaus Ejner

2018-03-01

Topical antipsoriatics are recommended first-line treatment of psoriasis, but rates of adherence are low. Patient support by use of electronic health (eHealth) services is suggested to improve medical adherence. To review randomised controlled trials (RCTs) testing eHealth interventions designed to improve adherence to topical antipsoriatics and to review applications for smartphones (apps) incorporating the word psoriasis. Literature review: Medline, Embase, Cochrane, PsycINFO and Web of Science were searched using search terms for eHealth, psoriasis and topical antipsoriatics. General analysis of apps: The operating systems (OS) for smartphones, iOS, Google Play, Microsoft Store, Symbian OS and Blackberry OS were searched for apps containing the word psoriasis. Literature review: Only one RCT was included, reporting on psoriasis patients' Internet reporting their status of psoriasis over a 12-month period. The rate of adherence was measured by Medication Event Monitoring System (MEMS ® ). An improvement in medical adherence and reduction of severity of psoriasis were reported. General analysis of apps: A total 184 apps contained the word psoriasis. There is a critical need for high-quality RCTs testing if the ubiquitous eHealth technologies, for example, some of the numerous apps, can improve psoriasis patients' rates of adherence to topical antipsoriatics.

Immunologic mechanisms play an integral role in understanding the pathogenesis and management of rheumatic conditions. Currently, there is limited access to formal instruction in immunology for rheumatology trainees across Canada. The aims of this study were (1) to describe current immunology curricula among adult rheumatology training programs across Canada and (2) to compare the perceived learning needs of rheumatology trainees from the perspective of program directors and trainees to help develop a focused nationwide immunology curriculum. Rheumatology trainees and program directors from adult rheumatology programs across Canada completed an online questionnaire and were asked to rank a comprehensive list of immunology topics. A modified Delphi approach was implemented to obtain consensus on immunology topics. Only 42% of program directors and 31% of trainees felt the current method of teaching immunology was effective. Results illustrate concordance between program directors and trainees for the highest-ranked immunology topics including innate immunity, adaptive immunity, and cells and tissues of the immune system. However, there was discordance among other topics, such as diagnostic laboratory immunology and therapeutics. There is a need to improve immunology teaching in rheumatology training programs. Results show high concordance between the basic immunology topics. This study provides the groundwork for development of future immunology curricula.

Topic models: A novel method for modeling couple and family text data

PubMed Central

Atkins, David C.; Rubin, Tim N.; Steyvers, Mark; Doeden, Michelle A.; Baucom, Brian R.; Christensen, Andrew

2012-01-01

Couple and family researchers often collect open-ended linguistic data – either through free response questionnaire items or transcripts of interviews or therapy sessions. Because participant's responses are not forced into a set number of categories, text-based data can be very rich and revealing of psychological processes. At the same time it is highly unstructured and challenging to analyze. Within family psychology analyzing text data typically means applying a coding system, which can quantify text data but also has several limitations, including the time needed for coding, difficulties with inter-rater reliability, and defining a priori what should be coded. The current article presents an alternative method for analyzing text data called topic models (Steyvers & Griffiths, 2006), which has not yet been applied within couple and family psychology. Topic models have similarities with factor analysis and cluster analysis in that topic models identify underlying clusters of words with semantic similarities (i.e., the “topics”). In the present article, a non-technical introduction to topic models is provided, highlighting how these models can be used for text exploration and indexing (e.g., quickly locating text passages that share semantic meaning) and how output from topic models can be used to predict behavioral codes or other types of outcomes. Throughout the article a collection of transcripts from a large couple therapy trial (Christensen et al., 2004) is used as example data to highlight potential applications. Practical resources for learning more about topic models and how to apply them are discussed. PMID:22888778

A systematic review of the evidence for topical use of ginger.

Ding, Mingshuang; Leach, Matthew J; Bradley, Helen

2013-01-01

The use of ginger as a topical intervention is widely advocated in the popular media. However, there has been no attempt to date to synthesize the evidence for topically administered ginger. To systematically review and synthesize the best available evidence of effectiveness for topical ginger in any condition. CAM on PubMed, CINAHL, Google Scholar, MEDLINE, National Library of Australia, The Cochrane Library, TRIP, pertinent texts, and bibliographies of relevant papers. Data sources were systematically searched for studies investigating the clinical effectiveness of topical ginger, in any form and for any condition, regardless of study design. Studies were limited to those published between 1980 and 2010, and published in English, Mandarin, Cantonese, or Taiwanese. Data were extracted by two authors, independently, using standardized templates. Four studies met the inclusion criteria, including three randomized controlled trials and one non-randomized controlled trial. All studies differed in terms of study population, outcome measures, comparative interventions, and dose and form of ginger used, and thus, were not amenable to meta-analysis. Findings from all trials favored usage of ginger for most outcomes. However, the small sample sizes and inadequate methodological reporting indicate a high risk of bias and the need for caution when interpreting these results. Few studies have investigated the effectiveness of topically administered ginger for any condition. Until the findings of these studies are corroborated by more robust research, and the safety of ginger is adequately established, clinicians should remain cautious about using topical ginger in clinical practice. © 2013 Elsevier Inc.

Mosquito repellents for malaria prevention

PubMed Central

Maia, Marta F; Kliner, Merav; Richardson, Marty; Lengeler, Christian; Moore, Sarah J

2018-01-01

Background Malaria is an important cause of illness and death across endemic regions. Considerable success against malaria has been achieved within the past decade mainly through long-lasting insecticide-treated nets (LLINs). However, elimination of the disease is proving difficult as current control methods do not protect against mosquitoes biting outdoors and when people are active. Repellents may provide a personal protection solution during these times. Objectives To assess the impact of topical repellents, insecticide-treated clothing, and spatial repellents on malaria transmission. Search methods We searched the following databases up to 26 June 2017: the Cochrane Infectious Diseases Group Specialized Register; the Central Register of Controlled Trials (CENTRAL), published in the Cochrane Library; MEDLINE; Embase; US AFPMB; CAB Abstracts; and LILACS. We also searched trial registration platforms and conference proceedings; and contacted organizations and companies for ongoing and unpublished trials. Selection criteria We included randomized controlled trials (RCTs) and cluster-randomized controlled trials of topical repellents proven to repel mosquitoes; permethrin-treated clothing; and spatial repellents such as mosquito coils. We included trials that investigated the use of repellents with or without LLINs, referred to as insecticide-treated nets. Data collection and analysis Two review authors independently reviewed trials for inclusion, extracted the data, and assessed the risk of bias. A third review author resolved any discrepancies. We analysed data by conducting meta-analysis and stratified by whether the trials had included LLINs. We combined results from cRCTs with individually RCTs by adjusting for clustering and presented results using forest plots. We used GRADE to assess the certainty of the evidence. Main results Eight cRCTs and two RCTs met the inclusion criteria. Six trials investigated topical repellents, two trials investigated insecticide-treated clothing, and two trials investigated spatial repellents. Topical repellents Six RCTS, five of them cluster-randomized, investigated topical repellents involving residents of malaria-endemic regions. Four trials used topical repellents in combination with nets, but two trials undertaken in displaced populations used topical repellents alone. It is unclear if topical repellents can prevent clinical malaria (RR 0.65, 95% CI 0.4 to 1.07, very low certainty evidence) or malaria infection (RR 0.84, 95% CI 0.64 to 1.12, low-certainty evidence) caused by P. falciparum. It is also unclear if there is any protection against clinical cases of P. vivax (RR 1.32, 95% CI 0.99 to 1.76, low-certainty evidence) or incidence of infections (RR 1.07, 95% CI 0.80 to 1.41, low-certainty evidence). Subgroup analysis of trials including insecticide-treated nets did not show a protective effect of topical repellents against malaria. Only two studies did not include insecticide-treated nets, and they measured different outcomes; one reported a protective effect against clinical cases of P. falciparum (RR 0.40, 95% CI 0.23 to 0.71); but the other study measured no protective effect against malaria infection incidence caused by either P. falciparum or P. vivax. Insecticide-treated clothing Insecticide-treated clothing were investigated in trials conducted in refugee camps in Pakistan and amongst military based in the Colombian Amazon. Neither study provided participants with insecticide-treated nets. In the absence of nets, treated clothing may reduce the incidence of clinical malaria caused by P. falciparum by approximately 50% (RR 0.49, 95% CI 0.29 to 0.83, low-certainty evidence) and P. vivax (RR 0.64, 95% CI 0.40 to 1.01, low-certainty evidence). Spatial repellents Two cluster-randomized RCTs investigated mosquito coils for malaria prevention. We do not know the effect of spatial repellents on malaria prevention (RR 0.24, 95% CI 0.03 to 1.72, very low certainty evidence). There was large heterogeneity between studies and one study had high risk of bias. Authors' conclusions There is insufficient evidence to conclude topical or spatial repellents can prevent malaria. There is a need for better designed trials to generate higher certainty of evidence before well-informed recommendations can be made. Adherence to daily compliance remains a major limitation. Insecticide-treated clothing may reduce risk of malaria infection in the absence of insecticide-treated nets; further studies on insecticide-treated clothing in the general population should be done to broaden the applicability of the results. Mosquito repellents for malaria prevention What was the aim of this review? The aim of this Cochrane Review was to find out if mosquito repellents — topical repellents (applied to the skin); insecticide-treated clothing; or spatial repellents such as mosquito coils — can prevent malaria. We collected and analysed the results of all relevant studies to answer this question and found data from ten trials: six on topical repellents, two on insecticide-treated clothing, and two on spatial repellents. Key messages We do not know if the use of repellent lotions or burning of mosquito coils can provide protection from malaria to communities living in endemic regions. In situations where long-lasting insecticide-treated bed nets (LLINs) cannot be rolled out, such as after a natural disaster or amongst displaced populations, the use of insecticide-treated clothing may reduce the risk of malaria infection by 50%. Most studies included in our analysis were poorly designed and had high risk of bias. In order to draw well-informed conclusions, further high-quality studies must be conducted to improve the certainty of the evidence. However, it is questionable if topical repellents can be used for malaria prevention in the general population as daily compliance and poor standardization (amount of repellent used, surface area applied, time of application, and period between repeated applications) are major limitations of this intervention. What was studied in this review Mosquito repellents provide protection from mosquito bites. There are three different types of repellents: topical repellents, which can be applied on the skin; insecticide-treated clothing, through impregnation of clothing with repellent compounds; and spatial repellents, such as mosquito coils. Malaria has decreased in many countries because people have been given highly effective LLINs. However people are still being bitten before they go to bed. There is a need to find a way to offer protection from malaria during these hours. Mosquito repellents may address this gap. What are the main results of the review? A total of six trials investigated the use of topical repellents for malaria prevention. The trials took place in different malaria-endemic regions across South America, Asia, and sub-Saharan Africa. The topical repellents tested included lotions, treated soap, and local cosmetics. We analysed the studies in groups according to LLIN inclusion. Most studies rolled out LLINs to the population and investigated topical repellents as a complementary intervention to the treated bed-nets. The poor design of the included studies provided low to very low certainty evidence, consequently we do not know if there is a benefit of using topical repellents in addition to LLINs to prevent malaria. The compliance of participants to adhere to the daily application of repellents remains a challenge to further research. Insecticide-treated clothing was investigated in two trials conducted with refugees in Pakistan and military deployed in the Amazon; neither study rolled out or reported the use of bed-nets. In the absence of LLINs, there is some evidence that insecticide-treated clothing may reduce the risk of malaria infection by 50%. Given that the findings relate to special populations living in particularly harsh conditions it is unclear if the results are applicable to the general population. Further studies involving civilian populations should be done to improve the certainty of these findings. Two studies investigated the practice of burning mosquito coils to reduce malaria infections. One study was conducted in China and the other in Indonesia. The study designs were substantially different and one study had high risk of bias leading to very low certainty evidence. We do not know if mosquito coils offer protection against malaria. The findings underline the need for further research. How up to date is this review? The review authors searched for studies that had been published up to 26 June 2017. PMID:29405263

Instruction in the responsible conduct of research (RCR) is required for all trainees funded by the National Institues of Health (NIH) or National Science Foundation (NSF). A recent Delphi study identified 53 key topics in 7 core areas that RCR education experts felt should be included in this instruction, which is required of many trainees in clinical and translational research. We performed a content analysis of major textbooks and online resources used in RCR instruction to determine the extent to which the 53 key topics identified in the Delphi study are covered by these resources. Textbooks and online resources used in RCR education at Clinical and Translational Science Award institutions were identified via survey. These resources were subjected to a content analysis. The 53 key topics identified in the Delphi study formed the basis of these analyses. We identified 10 textbooks and 1 online resource currently in use. Of the 53 key topics, only 4 were included in all 11 resources, and another 12 were included in 10. Twenty-three topics were covered in fewer than 65% of the resources, and two topics were absent from nearly all. Educators in clinical and translational research should be aware of key topics that are not covered in the RCR textbooks and online resources they may use and should consider augmenting discussion of such topics with other materials.

Difficult to control atopic dermatitis (AD) presents a therapeutic challenge and often requires combinations of topical and systemic treatment. Anti-inflammatory treatment of severe AD most commonly includes topical glucocorticosteroids and topical calcineurin antagonists used for exacerbation management and more recently for proactive therapy in selected cases. Topical corticosteroids remain the mainstay of therapy, the topical calcineurin inhibitors tacrolimus and pimecrolimus are preferred in certain locations. Systemic anti-inflammatory treatment is an option for severe refractory cases. Microbial colonization and superinfection contribute to disease exacerbation and thus justify additional antimicrobial / antiseptic treatment. Systemic antihistamines (H1) may relieve pruritus but do not have sufficient effect on eczema. Adjuvant therapy includes UV irradiation preferably of UVA1 wavelength. “Eczema school” educational programs have been proven to be helpful. PMID:23663504

PURPOSE: This study describes topics covered by coaches assisting teachers implementing a research-based drug prevention program and explores how coaching affected student outcomes. DESIGN: The All Stars drug prevention curriculum was implemented by 16 urban teachers who received four coaching sessions. Two coaches participated. Coaches were interviewed by investigators to assess topics covered. Students completed pretest-posttest measures of mediators and substance use behaviors. FINDINGS: The average teacher was coached on 11.7 different topics, out of a total of 23 topics. Coaching topics most heavily emphasized included: introduction and wrap up; time management; general classroom management; teacher's movement around the class; asking open-ended questions; using students' questions, comments and examples to make desired points; general preparation; engaging high-risk youth; reading from the curriculum; implementing activities correctly; focusing on objectives and goals; maintaining a focus on the task; and improving depth of understanding. Seven coaching topics were found to relate to changes in student mediators and behavior. RESEARCH LIMITATIONS/IMPLICATIONS: The current study was exploratory. Future research should explore how teachers develop the particular skills required by prevention programs and how coaches can assist them. PRACTICAL IMPLICATIONS: We postulate five levels of skill development which coaches may address: (1) fundamental teaching skills, (2) mechanics of program delivery, (3) development of an interactive teaching style, (4) effective response to student input, and (5) effective tailoring and adaptation. ORIGINALITY/VALUE: This represents one of a very few studies that explores how coaching impacts outcomes in substance abuse prevention.

Bonrath, E M; Grantcharov, T P

2015-08-01

The surgical treatment of paraesophageal hernias remains a challenge due to the lack of consensus regarding principles of operative treatment. The objectives of this study were to achieve consensus on key topics through expert opinion using a Delphi methodology. A Delphi survey combined with a face-to-face meeting was conducted. A panel of European experts in foregut surgery from high-volume centres generated items in the first survey round. In subsequent rounds, the panel rated agreement with statements on a 5-point Likert-type scale. Internal consistency (consensus) was predefined as Cronbach's α > .80. Items that >70 % of the panel either rated as irrelevant/unimportant, or relevant/important were selected as consensus items, while topics that did not reach this cut-off were termed "undecided/controversial". Three survey rounds were completed: 19 experts from 10 countries completed round one, 18 continued through rounds two and three. Internal consistency was high in rounds two and three (α > .90). Fifty-eight additional/revised items derived from comments and free-text entries were included in round three. In total, 118 items were rated; consensus agreement was achieved for 70 of these. Examples of consensus topics are the relevance of the disease profile for assessing surgical urgency and complexity, the role of clinical history as the mainstay of patient follow-up, indications for revision surgery, and training and credentialing recommendations. Topics with the most "undecided/controversial" items were follow-up, postoperative care and surgical technique. This Delphi study achieved expert consensus on key topics in the operative management of paraesophageal hernias, providing an overview of the current opinion among European foregut surgeons. Moreover, areas with substantial variability in opinions were identified reflecting the current lack of empirical evidence and opportunities for future research.

Screening, Surveillance, and Treatment of Anal Intraepithelial Neoplasia.

Long, Kevin C; Menon, Raman; Bastawrous, Amir; Billingham, Richard

2016-03-01

The prevalence of anal intraepithelial neoplasia has been increasing, especially in high-risk patients, including men who have sex with men, human immunodeficiency virus positive patients, and those who are immunosuppressed. Several studies with long-term follow-up have suggested that rate of progression from high-grade squamous intraepithelial lesions to invasive anal cancer is ∼ 5%. This number is considerably higher for those at high risk. Anal cytology has been used to attempt to screen high-risk patients for disease; however, it has been shown to have very little correlation to actual histology. Patients with lesions should undergo history and physical exam including digital rectal exam and standard anoscopy. High-resolution anoscopy can be considered as well, although it is of questionable time and cost-effectiveness. Nonoperative treatments include expectant surveillance and topical imiquimod or 5-fluorouracil. Operative therapies include wide local excision and targeted ablation with electrocautery, infrared coagulation, or cryotherapy. Recurrence rates remain high regardless of treatment delivered and surveillance is paramount, although optimal surveillance regimens have yet to be established.

The value of debriefing after an interprofessional simulated crisis is widely recognised; however, little is known about the content of debriefings and topics that prompt reflection. This study aimed to describe the content and topics that facilitate reflection among learners in two types of interprofessional team debriefings (with or without an instructor) following simulated practice. Interprofessional operating room (OR) teams (one anaesthesia trainee, one surgical trainee, and one staff circulating OR nurse) managed a simulated crisis scenario and were randomised to one of two debriefing groups. Within-team groups used low-level facilitation (i.e., no instructor but a one-page debriefing form based on the Ottawa Global Rating Scale). The instructor-led group used high-level facilitation (i.e., gold standard instructor-led debriefing). All debriefings were recorded, transcribed, and thematically analysed using the inductive qualitative methodology. Thirty-seven interprofessional team-debriefing sessions were included in the analysis. Regardless of group allocation (within-team or instructor-led), the debriefings centred on targeted crisis resource management (CRM) content (i.e., communication, leadership, situation awareness, roles, and responsibilities). In both types of debriefings, three themes emerged as topics for entry points into reflection: (1) the process of the debriefing itself, (2) experience of the simulation model, including simulation fidelity, and (3) perceived performance, including the assessment of CRM. Either with or without an instructor, interprofessional teams focused their debriefing discussion on targeted CRM content. We report topics that allowed learners to enter reflection. This is important for understanding how to maximise learning opportunities when creating education activities for healthcare providers that work in interprofessional settings.

Few studies have focused on therapeutic as well as side effects of tranexamic acid (TXA) as a topical drug compared to other topical drugs in treating melasma. The present study aimed to assess and compare the beneficial therapeutic effects and also side effects of local TXA in comparison with hydroquinone in treating women with melasma. This randomized double-blinded clinical trial was performed on 60 women who suffered from melasma and were referred to the skin disorders clinic at the Rasoul-e-Akram hospital in Tehran in 2015. The patients were then randomly assigned via computerized randomization to two groups: group A received TXA%5 (topically twice a day for 12 weeks in the location of the melasma) and group B (received hydroquinone 2% with the same treatment order). Prior to intervention and at 12 weeks after intervention, the intensity and extension of melasma were assessed based on the Melasma Area and Severity Index (MASI) scoring method. The mean MASI score in both treatment groups decreased considerably after completion of treatment and was not significant between the two groups. No side effects were detected in group A, but 10% of those in group B complained of drug-related side effects including erythema and skin irritation (p = 0.131). Regarding the level of patient satisfaction, the patients in group A had a significantly higher level of satisfaction level of 33.3% compared with 6.7% in group B (p = 0.015) (Fig. 9). Multivariate linear regression modeling with the presence of age, history of systemic disorder, drug history, and family history of melasma demonstrated no difference in the mean MASI between the two groups. Topical use of TXA significantly reduced both melanin level and MASI score. Given its high efficiency and low drug side effects, this regimen results in high patient satisfaction compared with topical hydroquinone. IRCT code: IRCT2016040627220N2.

2014-08-01

Topical treatment of skin diseases is an attractive strategy as it receives high acceptance from patients, resulting in higher compliance and therapeutic outcomes. Recently, the use of variable nanocarriers for dermal application has been widely explored, as they offer several advantages compared with conventional topical preparations, including higher skin penetration, controlled and targeted drug delivery and the achievement of higher therapeutic effects. This article will focus on skin inflammation or dermatitis as it is one of the most common skin problems, describing the different types and causes of dermatitis, as well as the typical treatment regimens. The potential use of nanocarriers for targeting skin inflammation and the achievement of higher therapeutic effects using nanotechnology will be explored.

Tensions on the Korean Peninsula remain high despite a long-term strategy by South Korea to increase inter-Korean exchanges in economics, culture, sports, and other topics. This is because the process of reconciliation has rarely extended to military and security topics and those initiatives that were negotiated have been ineffective. Bilateral interactions must include actions to reduce threats and improve confidence associated with conventional military forces (land, sea, and air) as well as nuclear, chemical, and biological activities that are applicable to developing and producing weapons of mass destruction (WMD). The purpose of this project is to develop concepts for inter-Koreanmore » confidence building measures (CBMs) for military and WMD topics that South Korea could propose to the North when conditions are right. This report describes the historical and policy context for developing security-related CBMs and presents an array of bilateral options for conventional military and WMD topics within a consistent framework. The conceptual CBMs address two scenarios: (1) improved relations where construction of a peace regime becomes a full agenda item in inter-Korean dialogue, and (2) continued tense inter-Korean relations. Some measures could be proposed in the short term under current conditions, others might be implemented in a series of steps, while some require a higher level of cooperation than currently exists. To support decision making by political leaders, this research focuses on strategies and policy options and does not include technical details.« less

Chronic, nonhealing wounds, foot ulcers, and lower extremity amputations are among the most problematic complications associated with diabetes mellitus. Standard care for diabetes-related chronic ulcers has included treatment of infection, weight off-loading, aggressive surgical débridement, and maintenance of a moist wound environment with frequent dressing changes. Yeast glucan is a particular high-molecular-weight polymer of β-(1,3)-glycosidic linkages of glycopyranose. We report our observations about the effectiveness of topically and orally administrated β-(1,3)-glucan for the treatment of chronic diabetic wounds and compare them to the literature results previously reported for similar wounds. Twenty-two patients with nonhealing ulcers associated with diabetes were included in this study. β-Glucan was given both orally and topically for the treatment of nonhealing ulcers. Macroscopic changes and surface areas of diabetic ulcers were recorded, and complete healing times were noted for each patient. A rapid decrease in size and healthy granulation were significantly observed in most patients. The duration of complete healing averaged 10.8 weeks (range 6-20 weeks). No adverse events were observed in the treatment period. The complete healing time was shorter than the results previously reported in the literature. Our observations support the view that application of glucan hastens epithelialization and wound closure, so topically and orally administered β-(1,3)-glucan therapy can help reverse some of the deficits in impaired healing diseases such as diabetes mellitus.

Primary and High School resources for teachers and students to improve the space physics education in Chile

Primary and High School educational programs in Chile include a wide geophysical section inside the natural sciences and physics courses. Unfortunately, teacher generally have a lack of preparation and knowledge in this field and there is small amount of available didactical material in the native languaje. This implies that in the reality the geophysical topics are ignored year after year in the school rooms. By the preparation of didactic material and web resources in magnetosphere, solar wind and solar topics, in accordance with the official programs of the Chilean Ministry of Education, we are collaborating to the outreach of the space physics in Chile. As the primary diffusion mechanism is the web, we hope that all the spanish talking community in Latin America can benefit from the public teaching resources that we are developing. There are a growing number of space scientist and graduate students volunteering for this endeavour.

Sub-Tenon's anaesthesia versus topical anaesthesia for cataract surgery.

PubMed

Guay, Joanne; Sales, Karl

2015-08-27

Local anaesthesia for cataract surgery can be provided by sub-Tenon's or topical anaesthesia. Both techniques offer possible advantages. This review, which originally was published in 2007 and was updated in 2014, was undertaken to compare these two anaesthetic techniques. Our objectives were to compare the effectiveness of topical anaesthesia (with or without intracameral local anaesthetic) versus sub-Tenon's anaesthesia in providing pain relief during cataract surgery. We reviewed pain during administration of anaesthesia, postoperative pain, surgical satisfaction with operating conditions and patient satisfaction with pain relief provided, and we looked at associated complications. We searched the Cochrane Central Register of Controlled Trials, MEDLINE and EMBASE (last search in November 2014) and the reference lists of published articles. We looked for conferences abstracts and trials in progress and placed no constraints on language or publication status. We included all randomized studies that compared sub-Tenon's anaesthesia versus topical anaesthesia for cataract surgery. We assessed trial quality and extracted data in the format allowing maximal data inclusion. We included eight studies in this updated review but could retain in the analysis only seven studies on 742 operated eyes of 617 participants. Two cross-over trials included 125 participants, and five parallel trials included 492 participants. These studies were published between 1997 and 2005. The mean age of participants varied from 71.5 years to 83.5 years. The female proportion of participants varied from 54% to 76%. Compared with sub-Tenon's anaesthesia, topical anaesthesia (with or without intracameral injection) for cataract surgery increases intraoperative pain but decreases postoperative pain at 24 hours. The amplitude of the effect (equivalent to 1.1 on a score from 0 to 10 for intraoperative pain, and to 0.2 on the same scale for postoperative pain at 24 hours), although statistically significant, was probably too small to be of clinical relevance. The quality of the evidence was rated as high for intraoperative pain and moderate for pain at 24 hours. We did find differences in pain during administration of local anaesthetic (low level of evidence), and indications that surgeon satisfaction (low level of evidence) and participant satisfaction (moderate level of evidence) were less with topical anaesthesia. There was not enough evidence to say that one technique would result in a higher or lower incidence of intraoperative complications compared with the other. Both topical anaesthesia and sub-Tenon's anaesthesia are accepted and safe methods of providing anaesthesia for cataract surgery. An acceptable degree of intraoperative discomfort has to be expected with either of these techniques. Randomized controlled trials on the effects of various strategies to prevent intraoperative pain during cataract surgery could prove useful.

USU has hosted Physics Day at Lagoon and has attracted more than 120,000 secondary educators and students over 21 years. During this educational day, students explore basic physics concepts and apply their classroom content outdoors, in real world applications. As part of the event, USU's Physics Department provides curriculum to be used at Lagoon, in similar outside venues, and in the classroom. One such educational instrument, which is a primary focus of this work, is student workbooks filled with activities ranging from very simple to more advanced topics. Workbooks cover the properties of waves, relative velocity, and acceleration, topics which have historically challenged students and future topics include kinematics, energy, and forces. The topics were selected based on requests from teachers throughout the Intermountain Region and identified deficiencies in student performance on core curriculum assessments. An innovative approach is to identify physical application of iPhone and Android smartphone software technologies, which make use of dynamic and kinematic sensors. These technologies will allow students to realize their ability to do quantitative physics calculations anywhere, anytime; a smart device which is highly salable to today's teenage learners. This also provides an exciting approach to more fully engage students in learning physics concepts.

The TMS Magnesium Committee has been actively involved in presenting cutting-edge research and development and the latest trends related to magnesium and its alloys to industry and academia. Topics including magnesium alloy development, applications, mechanism of deformation and corrosion, thermomechanical processing, modelling, etc. have been captured year after year through the Magnesium Technology symposium and conference proceedings at TMS and through special topics in JOM. Every year, based on the unanimous endorsement from the industry and academia, a topic is selected to address the latest developments within this subject in JOM. In continuation with last year’s coverage of Advances andmore » Achievements in In-Situ Analysis of Corrosions and Structure–Property Relationship in Mg Alloys,[1] this year’s topic focuses on the Corrosion of Magnesium in Multimaterial Systems. Magnesium, the lightest of all the structural materials, has garnered much interest in the transportation, electronics packaging, defense equipments and industries alike and are more commonly being incorporated in multimaterial design concepts.[2-4] However, the application of the same is limited due to its highly corrosive nature, and understanding and mitigating the corrosion of magnesium has been a major research challenge.« less

Topic segmentation via community detection in complex networks

Many real systems have been modeled in terms of network concepts, and written texts are a particular example of information networks. In recent years, the use of network methods to analyze language has allowed the discovery of several interesting effects, including the proposition of novel models to explain the emergence of fundamental universal patterns. While syntactical networks, one of the most prevalent networked models of written texts, display both scale-free and small-world properties, such a representation fails in capturing other textual features, such as the organization in topics or subjects. We propose a novel network representation whose main purpose is to capture the semantical relationships of words in a simple way. To do so, we link all words co-occurring in the same semantic context, which is defined in a threefold way. We show that the proposed representations favor the emergence of communities of semantically related words, and this feature may be used to identify relevant topics. The proposed methodology to detect topics was applied to segment selected Wikipedia articles. We found that, in general, our methods outperform traditional bag-of-words representations, which suggests that a high-level textual representation may be useful to study the semantical features of texts.

Topical treatment of onychomycoses is time consuming, cost-intensive and subject to relatively high failure rates. Light-based devices may be effective treatment modalities. Aim of this work: To compare the clinical and mycological efficacy of Nd-YAG laser versus topical terbinafine in the treatment of onychomycosis. This study included 40 patients with onychomycosis randomized to receive four sessions of Nd-YAG laser (group A) or topical terbinafine twice daily for six months (group B). Follow-up was performed monthly. Mycological examination was done at third and sixth months following the start of treatment. After six months, all patients in group A showed marked improvement, while in group B only 50% of patients showed mild to moderate improvement. In addition, by the end of six months, 80% of the patients in group A showed mycological clearance, while all patients in group B still had positive cultures. Long pulse Nd-YAG laser therapy of onychomycosis is a safe and efficient method for treating onychomycosis. It is especially beneficial in elderly, compromised and hepatopathic patients for whom other alternative treatments could present some risks.

Alkemio: association of chemicals with biomedical topics by text and data mining.

PubMed

Gijón-Correas, José A; Andrade-Navarro, Miguel A; Fontaine, Jean F

2014-07-01

The PubMed® database of biomedical citations allows the retrieval of scientific articles studying the function of chemicals in biology and medicine. Mining millions of available citations to search reported associations between chemicals and topics of interest would require substantial human time. We have implemented the Alkemio text mining web tool and SOAP web service to help in this task. The tool uses biomedical articles discussing chemicals (including drugs), predicts their relatedness to the query topic with a naïve Bayesian classifier and ranks all chemicals by P-values computed from random simulations. Benchmarks on seven human pathways showed good retrieval performance (areas under the receiver operating characteristic curves ranged from 73.6 to 94.5%). Comparison with existing tools to retrieve chemicals associated to eight diseases showed the higher precision and recall of Alkemio when considering the top 10 candidate chemicals. Alkemio is a high performing web tool ranking chemicals for any biomedical topics and it is free to non-commercial users. http://cbdm.mdc-berlin.de/∼medlineranker/cms/alkemio. © The Author(s) 2014.

Do existing research summaries on health systems match immunisation managers' needs in middle- and low-income countries? Analysis of GAVI health systems strengthening support

PubMed Central

2011-01-01

Background The GAVI Alliance was created in 2000 to increase access to vaccines. More recently, GAVI has supported evidence-based health systems strengthening to overcome barriers to vaccination. Our objectives were: to explore countries' priorities for health systems strengthening; to describe published research summaries for each priority area in relation to their number, quality and relevance; and to describe the use of national data from surveys in identifying barriers to immunisation. Methods From 44 health systems strengthening proposals submitted to GAVI in 2007 and 2008, we analysed the topics identified, the coverage of these topics by existing systematic reviews and the use of nation-wide surveys with vaccination data to justify the needs identified in the proposals. Results Thirty topics were identified and grouped into three thematic areas: health workforce (10 topics); organisation and management (14); and supply, distribution and maintenance (6). We found 51 potentially relevant systematic reviews, although for the topic that appeared most frequently in the proposals ('Health information systems') no review was identified. Thematic and geographic relevance were generally categorised as "high" in 33 (65%) and 25 (49%) reviews, respectively, but few reviews were categorised as "highly relevant for policy" (7 reviews, 14%). With regard to methodological quality, 14 reviews (27%) were categorised as "high". The number of topics that were addressed by at least one high quality systematic review was: seven of the 10 topics in the 'health workforce' thematic area; six of the 14 topics in the area of 'organisation and management'; and none of the topics in the thematic area of 'supply, distribution and maintenance'. Only twelve of the 39 countries with available national surveys referred to them in their proposals. Conclusion Relevant, high quality research summaries were found for few of the topics identified by managers. Few proposals used national surveys evidence to identify barriers to vaccination. Researchers generating or adapting evidence about health systems need to be more responsive to managers' needs. Use of available evidence from local or national surveys should be strongly encouraged.

Macular amyloidosis (MA) represents a common variant of primary localized cutaneous amyloidosis. It has a characteristic female predominance; none of the treatment modalities described is either curative or uniformly effective in patients with macular amyloidosis. To determine the effect of fractional CO 2 laser in macular amyloidosis in comparison to fractional CO 2 laser-assisted drug delivery of topical steroids and topical vitamin C, the study includes 10 female patients with cutaneous macular amyloidosis aged between 20 and 62 years. Patients were treated with four sessions of fractional CO 2 laser with 4 weeks interval. Laser treatments were performed using fractional CO 2 laser with the following parameters (power 18 W, spacing 800 μm, dwell time 600 μs, stacking 3). The lesion is divided into three areas: area 1, treated by fractional laser only; area 2, treated by fractional laser followed by topical corticosteroid application under occlusion for 24 h; and area 3, treated by fractional laser followed by topical vitamin C serum application under occlusion for 24 h. All lesions were examined clinically and histologically before the therapy and 1 month after the end of the therapy to evaluate the degree of improvement. All treated areas show significant decrease in pigmentation score after treatment, significant drop in rippling (P value < 0.016), and improvement of lichenification; as regards the histological improvement, there was a significant decrease of the amyloid amount after treatment. As regards the amyloid amount, results show significant decrease in the amount of amyloid in all of the three treated areas. Area 2 reported the highest decrease in the amyloid amount followed by areas 1 and 3. One patient (10%) was highly satisfied by the treatment, 6 (60%) reported moderate degree of satisfaction, while only 3 (30%) reported mild satisfaction. Minimal complication occurred in the form of post-inflammatory hyperpigmentation in 1 patient. None of the patients suffered pain, ulceration, or infection. Fractional CO 2 alone can be used to improve the texture of macular amyloidosis. If used to assist the delivery of topical steroids and topical vitamin C, improvement can be highly increased.

Construction of Context-Based Module: How OLED can be used as a Context in High School Chemistry Instruction

Anugrah, I. R.; Mudzakir, A.; Sumarna, O.

2017-09-01

Teaching materials used in Indonesia generally just emphasize remembering skill so that the students’ science literacy is low. Innovation is needed to transform traditional teaching materials so that it can stimulate students’ science literacy, one of which is by context-based approach. This study focused on the construction of context-based module for high school using Organic Light-Emitting Diode (OLED) topics. OLED was chosen because it is an up-to-date topic and relevant to real life. This study used Model of Educational Reconstruction (MER) to reconstruct science content structure about OLED through combining scientist’s perspectives with student’s preconceptions and national curriculum. Literature review of OLED includes its definition, components, characteristics and working principle. Student’s preconceptions about OLED are obtained through interviews. The result shows that student’s preconceptions have not been fully similar with the scientist’s perspective. One of the reasons is that some of the related Chemistry concepts are too complicated. Through curriculum analysis, Chemistry about OLED that are appropriate for high school are Bohr’s atomic theory, redox and organic chemistry including polymers and aromatics. The OLED context and its Chemistry concept were developed into context-based module by adapting science literacy-based learning. This module is expected to increase students’ science literacy performance.

OBJECTIVES: Current guidelines recommend topical steroids as first-line treatment for patients with eosinophilic esophagitis (EoE). However, the evidence for this approach has been inconsistent in earlier reports. This meta-analysis aimed to clarify the efficacy of topical steroid treatment in active EoE using updated evidence. METHODS: CENTRAL, MEDLINE and EMBASE databases were searched for randomized controlled trials (RCTs) published up to May 2014 that compared topical steroids with control treatments for active EoE. Study bias was assessed using the Cochrane Collaboration Tool, and outcomes were pooled using random effects models. The primary outcome was the mean change in eosinophil counts. Secondary outcomes were symptom responses and adverse events. RESULTS: In total, seven RCTs (226 patients) were included. Topical steroids were associated with a significant reduction in esophageal mucosal eosinophil counts compared with control therapy although substantial heterogeneity between studies was observed (weighted mean difference (WMD) −27.2, 95% confidence interval (CI) −45.3 to −9.1, I2=56.2%). Subgroup analysis indicated the reduction in eosinophil counts was only present in studies where a proton pump inhibitor (PPI) trial was used to exclude other diagnoses (WMD −46.3, 95% CI −61.3 to −31.4, I2=0.0%). Subdivision of studies on the use of a PPI trial also accounted for the majority of heterogeneity among RCTs. No clear trends in symptom resolution were observed. Eleven out of 127 patients who received topical steroids developed asymptomatic esophageal candidiasis. CONCLUSIONS: These data provide updated high-quality evidence that support current guidelines for first-line EoE treatment with topical steroids after an initial PPI trial to exclude non-EoE pathologies (PROSPERO ID: CRD42014008828).

Retrospective review. To identify the top 100 spine research topics. Recent advances in "machine learning," or computers learning without explicit instructions, have yielded broad technological advances. Topic modeling algorithms can be applied to large volumes of text to discover quantifiable themes and trends. Abstracts were extracted from the National Library of Medicine PubMed database from five prominent peer-reviewed spine journals (European Spine Journal [ESJ], The Spine Journal [SpineJ], Spine, Journal of Spinal Disorders and Techniques [JSDT], Journal of Neurosurgery: Spine [JNS]). Each abstract was entered into a latent Dirichlet allocation model specified to discover 100 topics, resulting in each abstract being assigned a probability of belonging in a topic. Topics were named using the five most frequently appearing terms within that topic. Significance of increasing ("hot") or decreasing ("cold") topic popularity over time was evaluated with simple linear regression. From 1978 to 2015, 25,805 spine-related research articles were extracted and classified into 100 topics. Top two most published topics included "clinical, surgeons, guidelines, information, care" (n = 496 articles) and "pain, back, low, treatment, chronic" (424). Top two hot trends included "disc, cervical, replacement, level, arthroplasty" (+0.05%/yr, P < 0.001), and "minimally, invasive, approach, technique" (+0.05%/yr, P < 0.001). By journal, the most published topics were ESJ-"operative, surgery, postoperative, underwent, preoperative"; SpineJ-"clinical, surgeons, guidelines, information, care"; Spine-"pain, back, low, treatment, chronic"; JNS- "tumor, lesions, rare, present, diagnosis"; JSDT-"cervical, anterior, plate, fusion, ACDF." Topics discovered through latent Dirichlet allocation modeling represent unbiased meaningful themes relevant to spine care.

Corneal anesthetic abuse and Candida keratitis.

PubMed

Chern, K C; Meisler, D M; Wilhelmus, K R; Jones, D B; Stern, G A; Lowder, C Y

1996-01-01

Topical corneal anesthetic abuse is a self-inflicted injury, causing profound corneal morbidity. Superimposed infection is an important complicating factor. The authors report four patients with confirmed topical anesthetic abuse of the cornea, in whom Candida keratitis developed. A retrospective review of the medical records of four patients with confirmed topical corneal anesthetic abuse and fungal keratitis. A 21-year-old woman, two 28-year-old women, and a 35-year-old man were included in the study. All these patients sustained a corneal injury, prompting the chronic use of topical anesthetics (0.5% proparacaine hydrochloride in 3 patients, and 0.5% tetracaine hydrochloride and 0.4% benoxinate hydrochloride in the other). Corneal findings included epithelial defects in all patients, focal infiltrate in one patient, and ring-shaped stromal infiltrate in three patients. Topical anesthetic was discontinued, all patients initially were treated empirically with antibacterial agents, and three patients received topical corticosteroids. Subsequent corneal cultures grew Candida spp, Candida albicans specifically in three patients, and local and systemic antifungal therapy was started. Corneas in two patients re-epithelialized; a conjunctival flap was performed on another patient with a descemetocele; and the remaining patient was lost to follow-up, although repeat fungal cultures yielded no growth. Corneal superinfection with Candida may occur during topical anesthetic abuse. Therapy includes discontinuation of the anesthetic and institution of antifungal therapy.

Although mental health information on the internet is often of poor quality, relatively little is known about the quality of websites, such as Wikipedia, that involve participatory information sharing. The aim of this paper was to explore the quality of user-contributed mental health-related information on Wikipedia and compare this with centrally controlled information sources. Content on 10 mental health-related topics was extracted from 14 frequently accessed websites (including Wikipedia) providing information about depression and schizophrenia, Encyclopaedia Britannica, and a psychiatry textbook. The content was rated by experts according to the following criteria: accuracy, up-to-dateness, breadth of coverage, referencing and readability. Ratings varied significantly between resources according to topic. Across all topics, Wikipedia was the most highly rated in all domains except readability. The quality of information on depression and schizophrenia on Wikipedia is generally as good as, or better than, that provided by centrally controlled websites, Encyclopaedia Britannica and a psychiatry textbook.

Evaluation of human response to structural vibration induced by sonic boom

NASA Technical Reports Server (NTRS)

Sutherland, L. C.; Czech, J.

1992-01-01

This paper addresses the topic of building vibration response to sonic boom and the evaluation of the associated human response to this vibration. The paper reexamines some of the issues addressed in the previous extensive coverage of the topic, primarily by NASA, and attempts to offer a fresh viewpoint for some of the problems that may assist in reassessing the potential impact of sonic boom over populated areas. The topics addressed are: (1) human response to vibration; (2) criteria for, and acoustic signature of rattle; (3) structural response to shaped booms, including definition of two new descriptors for assessing the structural response to sonic boom; and (4) a detailed review of the previous NASA/FAA Sonic Boom Test Program involving structural response measurements at Edwards AFB and an initial estimate of structural response to sonic booms from possible high speed civil transport configurations. Finally, these estimated vibration responses are shown to be substantially greater than the human response and rattle criteria developed earlier.

Teaching surgery, radiology and anatomy together: the mix enhances motivation and comprehension.

PubMed

Dettmer, Sabine; Tschernig, Thomas; Galanski, Michael; Pabst, Reinhard; Rieck, Bernd

2010-10-01

Preclinical and clinical topics are often separated in medical education. For example, surgery and radiology are often taught much later than anatomy. The aim of this study was to establish and to evaluate an interdisciplinary course combining these closely related subjects to enhance medical comprehension. Two tutorials each lasting one term were offered to second year medical students, in which clinical topics were implemented linking anatomy to surgical and radiological knowledge. A questionnaire was used to evaluate the success of this approach. The motivation of the students was above average and the practical work was done accurately. The students confirmed that the course improved anatomical comprehension (>95%) and that the learned matters were relevant for their future (90%). Furthermore, interest in the subjects was higher after the course (>85%). Critical suggestions were to extend the course and to include more topics. A mix of surgery, radiology and anatomy is a teaching concept, which leads to high acceptance and interest in medical students.

During the 8th Annual Academic Surgical Congress held in New Orleans, Louisiana, on February 5-7, 2013, the Association for Academic Surgery (AAS) Presidential Session was dedicated to the topic of publishing. A survey consisting of 37 questions on issues related to publishing was administered to the AAS membership 1 mo before the meeting. The results of the survey were then presented during the 2013 AAS Presidential Session. In addition, a panel of five editors from surgery journals relevant to the membership of the AAS was convened to discuss topics addressed in the results of the survey. These topics included: (1) how to publish in high-impact factor journals; (2) top five reasons why manuscripts get rejected; (3) the do's and don'ts of publishing (i.e., ethics of publishing); (4) how to get on an editorial board; and (5) the future of publishing. This review summarizes the contents of this AAS Presidential Session and provides information relevant for any academician, investigator, or scientist. Published by Elsevier Inc.

A study of topics for distance education-A survey of U.S. Fish and Wildlife Service employees

USGS Publications Warehouse

Ratz, Joan M.; Schuster, Rudy M.; Marcy, Ann H.

2011-01-01

The purpose of this study was to identify training topics and distance education technologies preferred by U.S. Fish and Wildlife Service employees. This study was conducted on behalf of the National Conservation Training Center to support their distance education strategy planning and implementation. When selecting survey recipients, we focused on employees in positions involving conservation and environmental education and outreach programming. We conducted the study in two phases. First, we surveyed 72 employees to identify useful training topics. The response rate was 61 percent; respondents were from all regions and included supervisors and nonsupervisors. Five topics for training were identified: creating and maintaining partnerships (partnerships), technology, program planning and development (program planning), outreach methods to engage the community (outreach methods), and evaluation methods. In the second phase, we surveyed 1,488 employees to assess preferences for training among the five topics identified in the first survey and preferences among six distance education technologies: satellite television, video conferencing, audio conferencing, computer mediated training, written resources, and audio resources. Two types of instructor-led training were included on the survey to compare to the technology options. Respondents were asked what types of information, such as basic facts or problem solving skills, were needed for each of the five topics. The adjusted response rate was 64 percent; respondents were from all regions and included supervisors and nonsupervisors. The results indicated clear preferences among respondents for certain training topics and technologies. All five training topics were valued, but the topics of partnerships and technology were given equal value and were valued more than the other three topics. Respondents indicated a desire for training on the topics of partnerships, technology, program planning, and outreach methods. For the six distance education technologies, respondents indicated different levels of usability and access. Audio conferencing and written resources were reported to be most usable and accessible. The ratings of technology usability/access differed according to region; respondents in region 9 rated most technologies higher on usability/access. Respondents indicated they would take courses through either onsite or distance education approaches, but they prefer onsite training for most topics and most types of information.

Topical Microbicides and HIV Prevention in the Female Genital Tract

PubMed Central

Cottrell, Mackenzie L; Kashuba, Angela D. M.

2014-01-01

Worldwide, HIV disproportionately affects women who are often unable to negotiate traditional HIV preventive strategies such as condoms. In the absence of an effective vaccine or cure, chemoprophylaxis may be a valuable self-initiated alternative. Topical microbicides have been investigated as one such option. The first generation topical microbicides were non-specific, broad-spectrum antimicrobial agents, including surfactants, polyanions, and acid buffering gels, that generally exhibited contraceptive properties. After extensive clinical study, none prevented HIV infection, and their development was abandoned. Second generation topical microbicides include agents with selective mechanisms of antiviral activity. Most are currently being used for, or have previously been explored as, drugs for treatment of HIV. The most advanced of these is tenofovir 1% gel: the first topical agent shown to significantly reduce HIV infection by 39% compared to placebo. This review summarizes the evolution of topical microbicides for HIV chemoprophylaxis, highlights important concepts learned, and offers current and future considerations for this area of research.

Development and classification of an operational definition of complementary and alternative medicine for the Cochrane Collaboration

PubMed Central

Wieland, L. Susan; Manheimer, Eric; Berman, Brian M.

2011-01-01

Over the past decade the Cochrane Collaboration has been an increasingly important source of information on complementary and alternative medicine (CAM) therapies. From 2007 to 2008 the Cochrane CAM Field developed a topics list that allowed us to categorize all 396 Cochrane reviews related to CAM (as of The Cochrane Library, Issue 4, 2009). This topics list is an advance in making Cochrane reviews on CAM topics accessible to the public. In this paper, we discuss challenges in developing the topics list, including developing an operational definition of CAM, deciding which reviews should be included within the CAM Field’s scope, developing the structured list of CAM Field-specific topics, and determining where in the topics list the reviews should be placed. Although aspects of our operational definition of CAM are open to revision, a standardized definition provides us with an objective, reproducible and systematic method for defining and classifying CAM therapies.

2017-01-01

To analyze coverage of comprehensive sex education (CSE) in high schools in Mexico and describe whether it is comprehensive, homogeneous and has continuity based on student reports of exposure to topics in three dimensions: reproductive and sexual health, self-efficacy and rights and relations. Within a probabilistic, cross-sectional survey with stratified, cluster sampling, a nationally representative sample of 3 824 adolescents attending 45 public and private high-schools in urban and rural areas completed questionnaires on CSE. The proportion of adolescents reporting having received sex education from school personnel varies depending on topics and grade level. Topics most frequently covered are those related to sexual and reproductive health while rights and relations are least frequently dealt with. Most sex education topics are covered during junior high school and much less frequently in elementary or high school. CSE needs to be comprehensive and homogenous in terms of content, ensure inclusion of priority topics, meet national and international recommendations, ensure continuity and adapt contents to student age through all education levels.

2010-06-01

Atopic dermatitis (AD) is a common chronic relapsing pruritic skin disease of dogs for which treatment has varied over time and geographical location. Recent high quality randomized controlled trials and systematic reviews have established which drugs are likely to offer consistent benefit. The International Task Force for Canine AD currently recommends a multi-faceted approach to treat dogs with AD. Acute flares should be treated with a combination of nonirritating baths and topical glucocorticoids, once an attempt has been made to identify and remove the suspected causes of the flare. Oral glucocorticoids and antimicrobial therapy must be added when needed. In dogs with chronic AD, a combination of interventions should be considered. Again, factors that trigger flares of AD must be identified and, if possible, avoided. Currently recognized flare factors include food, flea and environmental allergens, Staphylococcus bacteria and Malassezia yeast. Skin and coat hygiene and care must be improved by bathing with nonirritating shampoos and dietary supplementation with essential fatty acids. The severity of pruritus and skin lesions can be reduced with a combination of anti-inflammatory drugs. Currently, medications with good evidence of high efficacy include topical and oral glucocorticoids, and calcineurin inhibitors such as oral ciclosporin and topical tacrolimus. The dose and frequency of administration of these drugs should be tailored to each patient considering each drug's efficacy, adverse effects and cost. Allergen-specific immunotherapy should be offered, whenever feasible, in an attempt to prevent recurrence of clinical signs upon further exposure to environmental allergens to which the patient is hypersensitive.

Organization's Orderly Interest Exploration: Inception, Development and Insights of AIAA's Topics Database

NASA Technical Reports Server (NTRS)

Marshall, Jospeh R.; Morris, Allan T.

2007-01-01

Since 2003, AIAA's Computer Systems and Software Systems Technical Committees (TCs) have developed a database that aids technical committee management to map technical topics to their members. This Topics/Interest (T/I) database grew out of a collection of charts and spreadsheets maintained by the TCs. Since its inception, the tool has evolved into a multi-dimensional database whose dimensions include the importance, interest and expertise of TC members and whether or not a member and/or a TC is actively involved with the topic. In 2005, the database was expanded to include the TCs in AIAA s Information Systems Group and then expanded further to include all AIAA TCs. It was field tested at an AIAA Technical Activities Committee (TAC) Workshop in early 2006 through live access by over 80 users. Through the use of the topics database, TC and program committee (PC) members can accomplish relevant tasks such as: to identify topic experts (for Aerospace America articles or external contacts), to determine the interest of its members, to identify overlapping topics between diverse TCs and PCs, to guide new member drives and to reveal emerging topics. This paper will describe the origins, inception, initial development, field test and current version of the tool as well as elucidate the benefits and insights gained by using the database to aid the management of various TC functions. Suggestions will be provided to guide future development of the database for the purpose of providing dynamics and system level benefits to AIAA that currently do not exist in any technical organization.

2016-01-01

A partnershipship between Carthage College and the Appalachian Mountain Club has delivered a successful public education and outreach program that merges natural environment topics and astronomy. Over the four years of activity, over 25,000 people have received programming. The effort has trained nature educators, permanent and seasonal AMC staff, and undergraduate physics and astronomy students to integrate diverse topical material and deliver high quality programming to the lay public. Unique to the program is the holistic nature of the material delivered - an 'atypical' astronomy program. Linking observable characteristics of the natural world with astronomical history and phenomena, and emphasizing the unique sequence of events that have led to human life on Earth, the program has changed attitudes and behaviors among the public participants. Successful interventions have included hands-on observing programs (day and night) that link nature content to the observed objects; table-talk presentations on nature/astronomy topics; dark skies preservation workshops; and hands-on activities developed for younger audiences, including schools, camps, and family groups. An extensive evaluation and assessment effort managed by a leading sociologist has demonstrated the effectiveness of the approach, and contributed to continuous improvement in the program content and methods. This work was supported in part by NSF Grant 1432662.

A multimedia guide to spinal cord injury: empowerment through self instruction.

PubMed

Van Biervliet, A; Gest, T R

1995-01-01

The Spinal Cord Injury (SCI) Project is developing a series of instructional modules on SCI that will be distributed via CD-ROM for patient and family education. The modules are based on an instructional program and patient manual distributed by the Paralyzed Veterans of America. The program includes topics ranging from the anatomy and physiology of spinal cord injuries to legal rights established under the Americans With Disabilities Act. The SCI project expands on the instructional manual by combining digital multimedia techniques with motivational features such as games and personal guides. The user selects a personal guide from among a selection of individuals with spinal cord injuries to guide them through tutorials that include accounts of personal experiences. The guides appear in small video windows at various points throughout the tutorials and give personal insight into the topic at hand. The user can also query the other guides to hear their views on a topic. The user interface incorporates 'seamless access' features, which enable persons with a wide range of disabilities to use the program. Innovative features of these modules are the use of personal instructional guides, motivational games and activities, incorporation of alternative input or access strategies, and the use of high quality, low cost, multimedia production strategies.

To date, topical therapies guarantee a better delivery of high concentrations of pharmacologic agents to the soft periodontal tissue, gingiva, and periodontal ligament as well as to the hard tissue such as alveolar bone and cementum. Topical hyaluronic acid (HA) has recently been recognized as an adjuvant treatment for chronic inflammatory disease in addition to its use to improve healing after dental procedures. The aim of our work was to systematically review the published literature about potential effects of HA as an adjuvant treatment for chronic inflammatory disease, in addition to its use to improve healing after common dental procedures. Relevant published studies were found in PubMed, Google Scholar, and Ovid using a combined keyword search or medical subject headings. At the end of our study selection process, 25 relevant publications were included, three of them regarding gingivitis, 13 of them relating to chronic periodontitis, seven of them relating to dental surgery, including implant and sinus lift procedures, and the remaining three articles describing oral ulcers. Not only does topical administration of HA play a pivotal key role in the postoperative care of patients undergoing dental procedures, but positive results were also generally observed in all patients with chronic inflammatory gingival and periodontal disease and in patients with oral ulcers. © The Author(s) 2016.

To compare the efficacy and safety of topical non-steroidal anti-inflammatory drugs (NSAIDs), including salicylate, for the treatment of osteoarthritis (OA). PubMed, Embase, Cochrane Library and Web of Science were searched from 1966 to January 2017. Randomised controlled trials (RCTs) comparing topical NSAIDs with placebo or each other in patients with OA and observational studies comparing topical NSAIDs with no treatment or each other irrespective of disease were included. Two investigators identified studies and independently extracted data. Bayesian network and conventional meta-analyses were conducted. The primary outcomes were pain relief for RCTs and risk of adverse effects (AEs) for observational studies. 43 studies, comprising 36 RCTs (7 900 patients with OA) and seven observational studies (218 074 participants), were included. Overall, topical NSAIDs were superior to placebo for relieving pain (standardised mean difference (SMD)=-0.30, 95% CI -0.40 to -0.20) and improving function (SMD=-0.35, 95% CI -0.45 to -0.24) in OA. Of all topical NSAIDs, diclofenac patches were most effective for OA pain (SMD=-0.81, 95% CI -1.12 to -0.52) and piroxicam was most effective for functional improvement (SMD=-1.04, 95% CI -1.60 to -0.48) compared with placebo. Although salicylate gel was associated with higher withdrawal rates due to AEs, the remaining topical NSAIDs were not associated with any increased local or systemic AEs. Topical NSAIDs were effective and safe for OA. Diclofenac patches may be the most effective topical NSAID for pain relief. No serious gastrointestinal and renal AEs were observed in trials or the general population. However, confirmation of the cardiovascular safety of topical NSAIDs still warrants further observational study. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.
