Successful diagnosis, screening, and elimination of malaria critically depend on rapid and sensitive detection of this dangerous infection, preferably transdermally and without sophisticated reagents or blood drawing. Such diagnostic methods are not currently available. Here we show that the high optical absorbance and nanosize of endogenous heme nanoparticles called “hemozoin,” a unique component of all blood-stage malaria parasites, generates a transient vapor nanobubble around hemozoin in response to a short and safe near-infrared picosecond laser pulse. The acoustic signals of these malaria-specific nanobubbles provided transdermal noninvasive and rapid detection of a malaria infection as low as 0.00034% in animals without using any reagents or drawing blood. These on-demand transient events have no analogs among current malaria markers and probes, can detect and screen malaria in seconds, and can be realized as a compact, easy-to-use, inexpensive, and safe field technology.

2017-01-01

Summary Background Copy and paste functionality can support efficiency during clinical documentation, but may promote inaccurate documentation with risks for patient safety. The Partnership for Health IT Patient Safety was formed to gather data, conduct analysis, educate, and disseminate safe practices for safer care using health information technology (IT). Objective To characterize copy and paste events in clinical care, identify safety risks, describe existing evidence, and develop implementable practice recommendations for safe reuse of information via copy and paste. Methods The Partnership 1) reviewed 12 reported safety events, 2) solicited expert input, and 3) performed a systematic literature review (2010 to January 2015) to identify publications addressing frequency, perceptions/attitudes, patient safety risks, existing guidance, and potential interventions and mitigation practices. Results The literature review identified 51 publications that were included. Overall, 66% to 90% of clinicians routinely use copy and paste. One study of diagnostic errors found that copy and paste led to 2.6% of errors in which a missed diagnosis required patients to seek additional unplanned care. Copy and paste can promote note bloat, internal inconsistencies, error propagation, and documentation in the wrong patient chart. Existing guidance identified specific responsibilities for authors, organizations, and electronic health record (EHR) developers. Analysis of 12 reported copy and paste safety events was congruent with problems identified from the literature review. Conclusion Despite regular copy and paste use, evidence regarding direct risk to patient safety remains sparse, with significant study limitations. Drawing on existing evidence, the Partnership developed four safe practice recommendations: 1) Provide a mechanism to make copy and paste material easily identifiable; 2) Ensure the provenance of copy and paste material is readily available; 3) Ensure adequate staff training and education; 4) Ensure copy and paste practices are regularly monitored, measured, and assessed.

A novel game-like and creativity-conducive fMRI paradigm is developed to assess the neural correlates of spontaneous improvisation and figural creativity in healthy adults. Participants were engaged in the word-guessing game of Pictionary(TM), using an MR-safe drawing tablet and no explicit instructions to be "creative". Using the primary contrast of drawing a given word versus drawing a control word (zigzag), we observed increased engagement of cerebellum, thalamus, left parietal cortex, right superior frontal, left prefrontal and paracingulate/cingulate regions, such that activation in the cingulate and left prefrontal cortices negatively influenced task performance. Further, using parametric fMRI analysis, increasing subjective difficulty ratings for drawing the word engaged higher activations in the left pre-frontal cortices, whereas higher expert-rated creative content in the drawings was associated with increased engagement of bilateral cerebellum. Altogether, our data suggest that cerebral-cerebellar interaction underlying implicit processing of mental representations has a facilitative effect on spontaneous improvisation and figural creativity.

2016-01-01

The factors influencing the efficacy of ultrasound-guided thoracentesis catheter drainage were investigated in the present study. A retrospective analysis of clinical data from 435 patients who presented with a pleural effusion was performed. Patients were divided into a control group and an intervention group. Thirty-seven patients in the control group were given standard care using pleural puncture to draw the excess fluid. The 398 patients in the intervention group were treated using ultrasound-guided thoracentesis catheter drainage. The rate of successful drainage of a pleural effusion was significantly higher (P<0.05), while the rate of complication was lower, in the ultrasound-guided thoracentesis cases compared to standard care treatment. In conclusion, ultrasound-guided thoracentesis catheter drainage is an efficient, safe and minimally invasive procedure to alleviate pleural effusion. The efficacy of the procedure is related to the separation of pleural effusion, drainage tube type and tube diameter. PMID:28105155

Perceptual Drawing as a Learning Tool in a College Biology Laboratory

NASA Astrophysics Data System (ADS)

Landin, Jennifer

2011-12-01

The use of drawing in the classroom has a contentious history in the U.S. education system. While most instructors and students agree that the activity helps students focus and observe more details, there is a lack of empirical data to support these positions. This study examines the use of three treatments (writing a description, drawing a perceptual image, or drawing a perceptual image after participating in a short instructional lesson on perceptual drawing) each week over the course of a semester. The students in the "Drawing with Instruction" group exhibit a small but significantly higher level of content knowledge by the end of the semester. When comparing Attitude Toward Biology and Observational Skills among the three groups, inconclusive results restrict making any conclusions. Student perceptions of the task are positive, although not as strong as indicated by other studies. A student behavior observed during the first study led to another question regarding student cognitive processes, and demonstrated cognitive change in student-rendered drawings. The data from the second study indicate that hemispheric dominance or visual/verbal learning do not impact learning from perceptual drawing activities. However, conservatism and need for closure are inversely proportional to the change seen in student drawings over the course of a lesson. Further research is needed to verify these conclusions, as the second study has a small number of participants.

This study evaluates various options for full-scale modular configuration of forward osmosis (FO) process for osmotic dilution of seawater using wastewater for simultaneous desalination and water reuse through FO-reverse osmosis (RO) hybrid system. Empirical relationship obtained from one FO membrane element operation was used to simulate the operational performances of different FO module configurations. The main limiting criteria for module operation is to always maintain the feed pressure higher than the draw pressure throughout the housing module for safe operation without affecting membrane integrity. Experimental studies under the conditions tested in this study show that a single membrane housing cannot accommodate more than four elements as the draw pressure exceeds the feed pressure. This then indicates that a single stage housing with eight elements is not likely to be practical for safe FO operation. Hence, six different FO modular configurations were proposed and simulated. A two-stage FO configuration with multiple housings (in parallel) in the second stage using same or larger spacer thickness reduces draw pressure build-up as the draw flow rates are reduced to half in the second stage thereby allowing more than four elements in the second stage housing. The loss of feed pressure (pressure drop) and osmotic driving force in the second stage are compensated by operating under the pressure assisted osmosis (PAO) mode, which helps enhance permeate flux and maintains positive pressure differences between the feed and draw chamber. The PAO energy penalty is compensated by enhanced permeate throughput, reduced membrane area, and plant footprint. The contribution of FO/PAO to total energy consumption was not significant compared to post RO desalination (90%) indicating that the proposed two-stage FO modular configuration is one way of making the FO full-scale operation practical for FO-RO hybrid system.

Drawing conclusions: The effect of instructions on children's confabulation and fantasy errors.

PubMed

Macleod, Emily; Gross, Julien; Hayne, Harlene

2016-01-01

Drawing is commonly used in forensic and clinical interviews with children. In these interviews, children are often allowed to draw without specific instructions about the purpose of the drawing materials. Here, we examined whether this practice influenced the accuracy of children's reports. Seventy-four 5- and 6-year-old children were interviewed one to two days after they took part in an interactive event. Some children were given drawing materials to use during the interview. Of these children, some were instructed to draw about the event, and some were given no additional instructions at all. Children who were instructed to draw about the event, or who were interviewed without drawing, made few errors. In contrast, children who drew without being given specific instructions reported more errors that were associated with both confabulation and fantasy. We conclude that, to maximise accuracy during interviews involving drawing, children should be directed to draw specifically about the interview topic.

SGLT2 inhibitors: are they safe?

PubMed

Filippas-Ntekouan, Sebastian; Filippatos, Theodosios D; Elisaf, Moses S

2018-01-01

Sodium-glucose linked transporter type 2 (SGLT2) inhibitors are a relatively new class of antidiabetic drugs with positive cardiovascular and kidney effects. The aim of this review is to present the safety issues associated with SGLT2 inhibitors. Urogenital infections are the most frequently encountered adverse events, although tend to be mild to moderate and are easily manageable with standard treatment. Although no increased acute kidney injury risk was evident in the major trials, the mechanism of action of these drugs requires caution when they are administered in patients with extracellular volume depletion or with drugs affecting renal hemodynamics. Canagliflozin raised the risk of amputations and the rate of fractures in the CANVAS trial, although more data are necessary before drawing definite conclusions. The risk of euglycemic diabetic ketoacidosis seems to be minimal when the drugs are prescribed properly. Regarding other adverse events, SGLT2 inhibitors do not increase the risk of hypoglycemia even when co-administered with insulin, but a decrease in the dose of sulphonylureas may be needed. The available data do not point to a causative role of SGLT2 inhibitors on malignancy risk, however, these drugs should be used with caution in patients with known hematuria or history of bladder cancer. SGLT2 inhibitors seem to be safe and effective in the treatment of diabetes but more studies are required to assess their long-term safety.

Orbit selection and its impact on radiation warning architecture for a human mission to Mars.

PubMed

Turner, R E; Levine, J M

1998-01-01

With the recent announcement of the discovery of the possibility of life on Mars, there is renewed interest in Mars missions, perhaps eventually in human missions. Astronauts on such missions are at risk to occasional periods of enhanced high energy particle flux from the sun known as Solar Particle Events. These events can pose a substantial risk to the health of the astronauts and to the on-board electronics. Effective forecast and warning of these events could provide time to take steps to minimize the risk (retreating to a safe haven, shutting down sensitive equipment, etc.) Providing that forecast capability, will require additional monitoring capability. The extent of this architecture is sensitive to the orbit selected for the transfer to and from Mars. This paper looks at the major classes of Mars missions (Conjunction and Opposition) and sub-categories of these classes and draws conclusions on the number of monitoring satellites needed for each, with a goal to reducing total system cost through optimum orbit selection.

Maintaining financial independence in advanced age.

PubMed

Barber, Ann

2007-01-01

In an attempt to personalize Nobel Prize-winning financial literature, this article seeks to show how individuals can take responsibility for their own finances. For instance, before Markowitz's work, pension funds shied away from risky investments. Then, Markowitz proved that the safest portfolios are those that are diversified over many asset classes, including risky investments. More recently, Kahneman's psychological experiments proved that during uncertainty, people tend to generalize from a small number of representatives to the larger group. He warns us to collect data before drawing conclusions. Using such insights, this article shows how persons in advanced age can develop Investment Policy Statements (IPS) that tailor their financial resources to serve their life goals. This is accomplished safely and successfully by following some guidelines, based on lessons from the financial literature. These guidelines are as follows: (a) update IPS annually, (b) diversify annually by rebalancing, (c) match new liabilities to specific assets, (d) be aware of common errors, such as loss aversion, and (e) measure success by whether one's goals have been met.

Open, trusting relationships underpin safety in rural maternity a hermeneutic phenomenology study.

PubMed

Crowther, Susan; Smythe, Elizabeth

2016-11-24

There are interwoven personal, professional and organisational relationships to be navigated in maternity in all regions. In rural regions relationships are integral to safe maternity care. Yet there is a paucity of research on how relationships influence safety and nurture satisfying experiences for rural maternity care providers and mothers and families in these regions. This paper draws attention to how these relationships matter. This research is informed by hermeneutic phenomenology drawing on Heidegger and Gadamer. Thirteen participants were recruited via purposeful sampling and asked to share their experiences of rural maternity care in recorded unstructured in-depth interviews. Participants were women and health care providers living and working in rural regions. Recordings were transcribed and data interpretively analysed until a plausible and trustworthy thematic pattern emerged. Throughout the data the relational nature of rural living surfaced as an interweaving tapestry of connectivity. Relationships in rural maternity are revealed in myriad ways: for some optimal relationships, for others feeling isolated, living with discord and professional disharmony. Professional misunderstandings undermine relationships. Rural maternity can become unsustainable and unsettling when relationships break down leading to unsafeness. This study reveals how relationships are an important and vital aspect to the lived-experience of rural maternity care. Relationships are founded on mutual understanding and attuned to trust matter. These relationships are forged over time and keep childbirth safe and enable maternity care providers to work sustainably. Yet hidden unspoken pre-understandings of individuals and groups build tension in relationships leading to discord. Trust builds healthy rural communities of practice within which everyone can flourish, feel accepted, supported and safe. This is facilitated by collaborative learning activities and open respectful communication founded on what matters most (safe positive childbirth) whilst appreciating and acknowledging professional and personal differences.

The DAB model of drawing processes

NASA Technical Reports Server (NTRS)

Hochhaus, Larry W.

1989-01-01

The problem of automatic drawing was investigated in two ways. First, a DAB model of drawing processes was introduced. DAB stands for three types of knowledge hypothesized to support drawing abilities, namely, Drawing Knowledge, Assimilated Knowledge, and Base Knowledge. Speculation concerning the content and character of each of these subsystems of the drawing process is introduced and the overall adequacy of the model is evaluated. Second, eight experts were each asked to understand six engineering drawings and to think aloud while doing so. It is anticipated that a concurrent protocol analysis of these interviews can be carried out in the future. Meanwhile, a general description of the videotape database is provided. In conclusion, the DAB model was praised as a worthwhile first step toward solution of a difficult problem, but was considered by and large inadequate to the challenge of automatic drawing. Suggestions for improvements on the model were made.

2018-01-01

Objective: The purpose of this review was to objectively evaluate the effects of Baduanjin exercise on rehabilitative outcomes in stroke patients. Methods: Both Chinese and English electronic databases were searched for potentially relevant trials. Two review authors independently screened eligible trials against the inclusion criteria, extracted data, and assessed the methodological quality by using the revised PEDro scale. Meta-analysis was only performed for balance function. Results: In total, there were eight randomized controlled trials selected in this systematic review. The aggregated result of four trials has shown a significant benefit in favor of Baduanjin on balance function (Hedges’ g = 2.39, 95% CI 2.14 to 2.65, p < 0.001, I2 = 61.54). Additionally, Baduanjin exercise effectively improved sensorimotor function of lower extremities and ability of daily activities as well as reduced depressive level, leading to improved quality of life. Conclusion: Baduanjin exercise as an adjunctive and safe method may be conducive to help stroke patients achieve the best possible short-term outcome and should be integrated with mainstream rehabilitation programs. More rigorous randomized controlled trials with long-term intervention periods among a large sample size of stroke patients are needed to draw a firm conclusion regarding the rehabilitative effects for this population.

Angström-Brännström, Charlotte; Norberg, Astrid; Jansson, Lilian

2008-08-01

The aim of the study was to examine how children with chronic illnesses narrate their experience of being comforted in hospital. During interviews, seven children, 4-10 years old described their experiences and made drawings. Thematic content analysis revealed following themes: being physically close to one's family, feeling safe and secure, staff being there for the children, and children being there for parents and siblings. Mother was identified as the most important comforter. The findings suggest that trusting in the staff's knowledge and professional skills is a prerequisite for children to feel "at home", and safe in hospital. Being close to one's family is even more important.

Using Fuzzy Clustering for Real-time Space Flight Safety

NASA Technical Reports Server (NTRS)

Lee, Charles; Haskell, Richard E.; Hanna, Darrin; Alena, Richard L.

2004-01-01

To ensure space flight safety, it is necessary to monitor myriad sensor readings on the ground and in flight. Since a space shuttle has many sensors, monitoring data and drawing conclusions from information contained within the data in real time is challenging. The nature of the information can be critical to the success of the mission and safety of the crew and therefore, must be processed with minimal data-processing time. Data analysis algorithms could be used to synthesize sensor readings and compare data associated with normal operation with the data obtained that contain fault patterns to draw conclusions. Detecting abnormal operation during early stages in the transition from safe to unsafe operation requires a large amount of historical data that can be categorized into different classes (non-risk, risk). Even though the 40 years of shuttle flight program has accumulated volumes of historical data, these data don t comprehensively represent all possible fault patterns since fault patterns are usually unknown before the fault occurs. This paper presents a method that uses a similarity measure between fuzzy clusters to detect possible faults in real time. A clustering technique based on a fuzzy equivalence relation is used to characterize temporal data. Data collected during an initial time period are separated into clusters. These clusters are characterized by their centroids. Clusters formed during subsequent time periods are either merged with an existing cluster or added to the cluster list. The resulting list of cluster centroids, called a cluster group, characterizes the behavior of a particular set of temporal data. The degree to which new clusters formed in a subsequent time period are similar to the cluster group is characterized by a similarity measure, q. This method is applied to downlink data from Columbia flights. The results show that this technique can detect an unexpected fault that has not been present in the training data set.

Drawing in nursing PBL.

PubMed

Chan, Zenobia C Y

2013-08-01

The implementation of art education in nursing is said to have positive effects on nursing students. Most studies applied visual art dialogues or object design, whereas the effectiveness of drawing as a teaching and learning method is rarely examined and discussed. This paper aimed to discuss the potential and effectiveness of drawing as a learning and teaching method. Four drawings which were created by Hong Kong nursing students are demonstrated and the students' perspectives of how drawing enhanced learning are shown in this paper. Topics on drawing as a fun teaching and learning method and the way it can enhance critical thinking and creativity are also discussed. In conclusion, the activity was a great success, and students enjoyed the learning process and reflected positive comments. However, we cannot conclude that drawing is an effective teaching and learning method based on a single paper, therefore more similar studies should be conducted to investigate this method.

When assessing the relationship between direction and orientation in drawings by young children and adults, Taguchi and Noma used a fish-drawing task. However, the fish is not convenient enough as an object for such a task so it is highly preferable to use, instead of a single object, a set of several objects to assess directionality quantitatively. These authors' conclusions do not acknowledge alternative explanations.

The US FDA and animal cloning: risk and regulatory approach.

PubMed

Rudenko, Larisa; Matheson, John C

2007-01-01

The Food and Drug Administration's (FDA's) Center for Veterinary Medicine issued a voluntary request to producers of livestock clones not to introduce food from clones or their progeny into commerce until the agency had assessed whether production of cattle, swine, sheep, or goats by somatic cell nuclear transfer (SCNT) posed any unique risks to the animal(s) involved in the process, humans, or other animals by consuming food from those animals, compared with any other assisted reproductive technology (ART) currently in use. Following a comprehensive review, no anomalies were observed in animals produced by cloning that have not also been observed in animals produced by other ARTs and natural mating. Further systematic review on the health of, and composition of meat and milk from, cattle, swine, and goat clones and the progeny of cattle and sheep did not result in the identification of any food-consumption hazards. The agency therefore concluded that food from cattle, swine, and goat clones was as safe to eat as food from animals of those species derived by conventional means. The agency also concluded that food from the progeny of the clone of any species normally consumed for food is as safe to eat as those animals. The article also describes the methodology used by the agency to analyze data and draw these conclusions, the plans the agency has proposed to manage any identified risks, and the risk communication approaches the agency has used.

Practice-specific risk perceptions and self-reported food safety practices.

The relationship between risk perception and risk avoidance is typically analyzed using self-reported measures. However, in domains such as driving or food handling, the validity of responses about usual behavior is threatened because people think about the situations in which they are self-aware, such as when they encounter a hazard. Indeed, researchers have often noted a divergence between what people say about their behavior and how they actually behave. Thus, in order to draw conclusions about risk perceptions and risk avoidance from survey data, it is important to identify particular cognitive elements, such as those measured by questions about risk and safety knowledge, risk perceptions, or information search behavior, which may be effective antecedents of self-reported safety behavior. It is also important to identify and correct for potential sources of bias that may exist in the data. The authors analyze the Food and Drug Administration's 1998 Food Safety Survey to determine whether there are consistent cognitive antecedents for three types of safe food practices: preparation, eating, and cooling of foods. An assessment of measurement biases shows that endogeneity of food choices affects reports of food preparation. In addition, response bias affects reports of cooling practices as evidenced by its relation to knowledge and information search, a pattern of cognitive effects unique to cooling practices. After correcting for these biases, results show that practice-specific risk perceptions are the primary cognitive antecedents of safe food behavior, which has implications for the design of effective education messages about food safety.

Exploring the influence of workplace supports and relationships on safe medication practice: A pilot study of Australian graduate nurses.

PubMed

Sahay, Ashlyn; Hutchinson, Marie; East, Leah

2015-05-01

Despite the growing awareness of the benefits of positive workplace climates, unsupportive and disruptive workplace behaviours are widespread in health care organisations. Recent graduate nurses, who are often new to a workplace, are particularly vulnerable in unsupportive climates, and are also recognised to be at higher risk for medication errors. Investigate the association between workplace supports and relationships and safe medication practice among graduate nurses. Exploratory study using quantitative survey with a convenience sample of 58 nursing graduates in two Australian States. Online survey focused on graduates' self-reported medication errors, safe medication practice and the nature of workplace supports and relationships. Spearman's correlations identified that unsupportive workplace relationships were inversely related to graduate nurse medication errors and erosion of safe medication practices, while supportive Nurse Unit Manager and supportive work team relationships positively influenced safe medication practice among graduates. Workplace supports and relationships are potentially both the cause and solution to graduate nurse medication errors and safe medication practices. The findings develop further understanding about the impact of unsupportive and disruptive behaviours on patient safety and draw attention to the importance of undergraduate and continuing education strategies that promote positive workplace behaviours and graduate resilience.

Generating political will for safe motherhood in Indonesia.

PubMed

Shiffman, Jeremy

2003-03-01

In 1987 an international conference brought global attention to an issue that previously had been ignored: the world's alarmingly high number of maternal deaths in childbirth. The conference ended with a declaration calling for a reduction in maternal mortality by at least half by the year 2000. As the deadline approached, safe motherhood activists lamented the fact that the world was nowhere near to achieving this objective. They attributed this failure to a variety of causes, but were in agreement that the medical technology was available to prevent maternal deaths in childbirth, and the key was generating the political will to make such technology widely available to women in developing countries.What 'political will' means, however, has been left as an unopened black box. What causes governments to give priority to the issue of safe motherhood, given that national political systems are burdened with thousands of issues to sort through each year? In marked contrast to our extensive knowledge about the medical interventions necessary to prevent maternal death, we know little about the political interventions necessary to increase the likelihood that national leaders pay meaningful attention to the issue. Drawing from a scholarly literature on agenda setting, this paper identifies four factors that heighten the likelihood that an issue will rise to national-level attention: the existence of clear indicators showing that a problem exists; the presence of effective political entrepreneurs to push the cause; the organization of attention-generating focusing events that promote widespread concern for the issue; and the availability of politically palatable policy alternatives that enable national leaders to understand that the problem is surmountable. The paper presents a case study of the emergence, waning and re-generation of political priority for safe motherhood in Indonesia over the decade 1987-1997, to highlight how these four factors interacted to raise safe motherhood from near obscurity in the country to national-level prominence. While there are contextual factors that make this case unique, some elements are applicable to all developing countries. The paper draws out these dimensions in the hope that greater knowledge surrounding how political will actually has been generated can help shape strategic action to address this much neglected global problem.

Using biological principles to design MEMS

NASA Astrophysics Data System (ADS)

Scherge, M.; Gorb, S. N.

2000-09-01

In micromechanics the handling and positioning of microparts involves sophisticated assembly procedures and a good understanding of microtribological phenomena. Due to the very low object mass, adhesion between the micropart and the handling tool (usually a mechanical gripper) becomes a performance-limiting factor. Adhesion effects can be even larger than the force that frees the micropart from the handling tool thus making correct positioning impossible. Many useful design principles for optimized adhesion properties can be found in biological systems. In this paper adhesion between the foot of an insect and a surface was evaluated. The attachment pads of the great green bush cricket (Tettigonia viridissima) - used to attach the insect safely to a variety of different surfaces - were investigated to draw conclusions that could be implemented in future technical microsystems. It is shown that the attachment pads are flexible micromechanical units capable of self-adjusting to different scales of roughness. The erratic influence of capillary action due to adsorbed water is presumably suppressed by a hydrophobic layer on the pads. Attaching and releasing mechanisms as well as accurate measurement of the adhesion force are discussed in detail.

2018-01-01

Background The aim of this study was to evaluate the use of the Diagnostic Drawing Series (DDS) as a screening tool for the breast cancer patients with psychological distress. Methods All of 64 patients with breast cancer participated in this study. Patients' depressive and anxiety symptoms were assessed using Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7) when the DDS was applied to the partipicants. Results Depressed patients used more enclosure in the Feeling drawings (P = 0.002) and tilt in Free drawings (P = 0.048). Patients with anxiety drew a picture over 67% of the paper (P = 0.015) in Tree drawing and more medium pressure (P = 0.049) in Feeling drawings. Thirty four subjects (77.3%) of unstable emotion group used over 67% of the space (P = 0.002). More Landscapes were observed in the Feeling drawings of unstable patients (P = 0.042). Conclusion These results suggested that DDS could be used as a supplemental screening tool for psychological distress in breast cancer patients. PMID:29686600

Brief report: new evidence for a social-specific imagination deficit in children with autism spectrum disorder.

PubMed

Ten Eycke, Kayla D; Müller, Ulrich

2015-01-01

Previous research suggests that children with autism have deficits in drawing imaginative content. However, these conclusions are largely based on tasks that require children to draw impossible persons, and performance on this task may be limited by social deficits. To determine the generality of the deficit in imagination in children with autism, we asked 25 children with autism (mean age 9;7) and 29 neurotypically developing children (mean age 8;7) to draw an imaginative person and house. Drawings of imaginary houses by children with autism did not differ from those by neurotypically developing controls, but drawings of persons were significantly less imaginative. These findings suggest that the impairment in imagination among children with autism may be specific to social stimuli.

Objective: The purpose of this descriptive pilot study was to assess the ability of youth to create a meaningful drawing related to living with type 1 diabetes and explore the benefits of expressing emotion through drawing in future interventional work. Methods: Youth aged 4 to 19 years (N = 242) with type I diabetes attending routine follow-up appointments within a pediatric specialty clinic were asked to draw: “If diabetes had a face what would it look like?” Results: Drawings reflected many emotions and ranged from simple to complex in detail. Drawings reflected multiple experiences of living with diabetes including emotions, tools used for management, and effects of self-care. Conclusions: Youth were able to create drawings reflecting their experience of living with diabetes. Youth conveyed a variety of emotions, attitudes, and experiences in drawing the “face” of diabetes. Drawing during clinic visits provides opportunity to explore the unspoken experiences of living with a chronic health condition, which may not be obtained during routine clinical information gathering. Deeper understanding of patient’s lived experience may assist providers in therapeutic management. PMID:28725833

Seizure drawings: insight into the self-image of children with epilepsy.

Epilepsy is a chronic disorder that is associated with numerous psychological challenges, especially in children. Drawings have been underutilized as a method to obtain insight into psychological issues in children with epilepsy. We asked 105 children with epilepsy, ages 5 to 18 years, to draw a picture of what it is like to have a seizure. Across ages and epilepsy syndromes, the drawings showed evidence of impaired self-concept, low self-esteem, and a sense of helplessness and vulnerability. Overall, the drawings of human figures were less developed than expected for chronological age. In some drawings, indicators of underlying depression were found. When considered by epilepsy syndrome or seizure type, some specific artistic features were noted. Children with simple partial (motor) seizures drew distorted body parts, especially limbs. Those with complex partial seizures depicted sensory symptoms and mental status changes such as confusion. Children with generalized tonic-clonic seizures showed shaking extremities. Drawings by children with absence seizures illustrated mainly staring. In conclusion, drawings are a powerful method to examine the self-concept of children with epilepsy and gain insight into their feelings about themselves and their world.

Facilitating HIV status disclosure for pregnant women and partners in rural Kenya: a qualitative study

PubMed Central

2013-01-01

Background Women’s ability to safely disclose their HIV-positive status to male partners is essential for uptake and continued use of prevention of mother-to-child transmission (PMTCT) services. However, little is known about the acceptability of potential approaches for facilitating partner disclosure. To lay the groundwork for developing an intervention, we conducted formative qualitative research to elicit feedback on three approaches for safe HIV disclosure for pregnant women and male partners in rural Kenya. Methods This qualitative acceptability research included in-depth interviews with HIV-infected pregnant women (n = 20) and male partners of HIV-infected women (n = 20) as well as two focus groups with service providers (n = 16). The participants were recruited at health care facilities in two communities in rural Nyanza Province, Kenya, during the period June to November 2011. Data were managed in NVivo 9 and analyzed using a framework approach, drawing on grounded theory. Results We found that facilitating HIV disclosure is acceptable in this context, but that individual participants have varying expectations depending on their personal situation. Many participants displayed a strong preference for couples HIV counseling and testing (CHCT) with mutual disclosure facilitated by a trained health worker. Home-based approaches and programs in which pregnant women are asked to bring their partners to the healthcare facility were equally favored. Participants felt that home-based CHCT would be acceptable for this rural setting, but special attention must be paid to how this service is introduced in the community, training of the health workers who will conduct the home visits, and confidentiality. Conclusion Pregnant couples should be given different options for assistance with HIV disclosure. Home-based CHCT could serve as an acceptable method to assist women and men with safe disclosure of HIV status. These findings can inform the design and implementation of programs geared at promoting HIV disclosure among pregnant women and partners, especially in the home-setting. PMID:24294994

1999-01-01

The present research was conducted in support of the NASA Safe All-Weather Flight Operations for Rotorcraft (SAFOR) program. The purpose of the work was to investigate the utility of two measurement tools developed by the British Defense Evaluation Research Agency. These tools were a subjective workload assessment scale, the DRA Workload Scale (DRAWS), and a situation awareness measurement tool in which the crews self-evaluation of performance is compared against actual performance. These two measurement tools were evaluated in the context of a test of an innovative approach to alerting the crew by way of a helmet mounted display. The DRAWS was found to be usable, but it offered no advantages over extant scales, and it had only limited resolution. The performance self-evaluation metric of situation awareness was found to be highly effective.

The role of effective connectivity between the task-positive and task-negative network for evidence gathering [Evidence gathering and connectivity].

Reports linking a 'jumping-to-conclusions' bias to delusions have led to growing interest in the neurobiological correlates of probabilistic reasoning. Several brain areas have been implicated in probabilistic reasoning; however, findings are difficult to integrate into a coherent account. The present study aimed to provide additional evidence by investigating, for the first time, effective connectivity among brain areas involved in different stages of evidence gathering. We investigated evidence gathering in 25 healthy individuals using fMRI and a new paradigm (Box Task) designed such as to minimize the effects of cognitive effort and reward processing. Decisions to collect more evidence ('draws') were contrasted to decisions to reach a final choice ('conclusions') with respect to BOLD activity. Psychophysiological interaction analysis was used to investigate effective connectivity. Conclusion events were associated with extensive brain activations in widely distributed brain areas associated with the task-positive network. In contrast, draw events were characterized by higher activation in areas assumed to be part of the task-negative network. Effective connectivity between the two networks decreased during draws and increased during conclusion events. Our findings indicate that probabilistic reasoning may depend on the balance between the task-positive and task-negative network, and that shifts in connectivity between the two may be crucial for evidence gathering. Thus, abnormal connectivity between the two systems may significantly contribute to the jumping-to-conclusions bias. Copyright © 2018 Elsevier Inc. All rights reserved.

Private-public sector co-operation to improve pesticide safety standards in developing countries.

PubMed

Ellis, W W

1998-01-01

This paper draws on the author's experiences of the pilot phase of the Safe Use Project (SUP) in Thailand; this project is a part of a major GIFAP initiative carried out in some developing countries. The SUP's objectives were; i) to raise awareness and compliance in the safe handling and storage of pesticides within the industry, the medical profession and the end-users; ii) to reduce the incidence of pesticide poisoning; iii) to protect the environment; iiii) to help relevant government agencies with resources, expertise and training. To achieve those objectives, the SUP used local-language training resources, provided basic training, lobbied for changes in governmental policies and regulations, and acted as a focal point for pesticide safety-related information. The SUP targeted the whole distribution chain, from importer/formulator, through to the endusers. Also medical profession, teachers and school students were targeted. On the base of independent audit and surveys, a general improvement in awareness has been shown within targeted groups; a longer time frame is required to detect meaningful changes in farmer practice. The SUP key programmes have been: I) training of trainers, retailers and farmers; II) schools programme; III) medical training; IV) protective clothing; V) industry standards; VI) model farm. The main conclusions of the pilot phase were: i) pesticide safety needs to be addressed by all concerned agencies in a joint effort; ii) a rural development perspective must be adopted in improving pesticide safety; iii) integrated pest management training programmes must include precautionary advice for proper handling, use and disposal of pesticides, wherever these are necessary.

Developing the practice context to enable more effective pain management with older people: an action research approach

PubMed Central

2011-01-01

Background This paper, which draws upon an Emancipatory Action Research (EAR) approach, unearths how the complexities of context influence the realities of nursing practice. While the intention of the project was to identify and change factors in the practice context that inhibit effective person-centred pain management practices with older people (65 years or older), reflective critical engagement with the findings identified that enhancing pain management practices with older people was dependent on cultural change in the unit as a whole. Methods An EAR approach was utilised. The project was undertaken in a surgical unit that conducted complex abdominal surgery. Eighty-five percent (n = 48) of nursing staff participated in the two-year project (05/NIR02/107). Data were obtained through the use of facilitated critical reflection with nursing staff. Results Three key themes (psychological safety, leadership, oppression) and four subthemes (power, horizontal violence, distorted perceptions, autonomy) were found to influence the way in which effective nursing practice was realised. Within the theme of 'context,' effective leadership and the creation of a psychologically safe environment were key elements in the enhancement of all aspects of nursing practice. Conclusions Whilst other research has identified the importance of 'practice context' and models and frameworks are emerging to address this issue, the theme of 'psychological safety' has been given little attention in the knowledge translation/implementation literature. Within the principles of EAR, facilitated reflective sessions were found to create 'psychologically safe spaces' that supported practitioners to develop effective person-centred nursing practices in complex clinical environments.

Background and purpose - Hip dislocation is one of the most common complications following total hip arthroplasty (THA). Several factors that affect dislocation have been identified, including acetabular cup positioning. Optimal values for cup inclination and anteversion are debatable. We performed a systematic review to describe the different methods for measuring cup placement, target zones for cup positioning, and the association between cup positioning and dislocation following primary THA. Methods - A systematic search of literature in the PubMed database was performed (January and February 2016) to identify articles that compared acetabular cup positioning and the risk of dislocation. Surgical approach and methods for measurement of cup angles were also considered. Results - 28 articles were determined to be relevant to our research question. Some articles demonstrated that cup positioning influenced postoperative dislocation whereas others did not. The majority of articles could not identify a statistically significant difference between dislocating and non-dislocating THA with regard to mean angles of cup anteversion and inclination. Most of the articles that assessed cup placement within the Lewinnek safe zone did not show a statistically significant reduction in dislocation rate. Alternative target ranges have been proposed by several authors. Interpretation - The Lewinnek safe zone could not be justified. It is difficult to draw broad conclusions regarding a definitive target zone for cup positioning in THA, due to variability between studies and the likely multifactorial nature of THA dislocation. Future studies comparing cup positioning and dislocation rate should investigate surgical approach separately. Standardized tools for measurement of cup positioning should be implemented to allow comparison between studies.

The genesis of errors in drawing.

Chamberlain, Rebecca; Wagemans, Johan

2016-06-01

The difficulty adults find in drawing objects or scenes from real life is puzzling, assuming that there are few gross individual differences in the phenomenology of visual scenes and in fine motor control in the neurologically healthy population. A review of research concerning the perceptual, motoric and memorial correlates of drawing ability was conducted in order to understand why most adults err when trying to produce faithful representations of objects and scenes. The findings reveal that accurate perception of the subject and of the drawing is at the heart of drawing proficiency, although not to the extent that drawing skill elicits fundamental changes in visual perception. Instead, the decisive role of representational decisions reveals the importance of appropriate segmentation of the visual scene and of the influence of pictorial schemas. This leads to the conclusion that domain-specific, flexible, top-down control of visual attention plays a critical role in development of skill in visual art and may also be a window into creative thinking.

Bourqui, Romain; Cottret, Ludovic; Lacroix, Vincent; Auber, David; Mary, Patrick; Sagot, Marie-France; Jourdan, Fabien

2007-01-01

Background The tools that are available to draw and to manipulate the representations of metabolism are usually restricted to metabolic pathways. This limitation becomes problematic when studying processes that span several pathways. The various attempts that have been made to draw genome-scale metabolic networks are confronted with two shortcomings: 1- they do not use contextual information which leads to dense, hard to interpret drawings, 2- they impose to fit to very constrained standards, which implies, in particular, duplicating nodes making topological analysis considerably more difficult. Results We propose a method, called MetaViz, which enables to draw a genome-scale metabolic network and that also takes into account its structuration into pathways. This method consists in two steps: a clustering step which addresses the pathway overlapping problem and a drawing step which consists in drawing the clustered graph and each cluster. Conclusion The method we propose is original and addresses new drawing issues arising from the no-duplication constraint. We do not propose a single drawing but rather several alternative ways of presenting metabolism depending on the pathway on which one wishes to focus. We believe that this provides a valuable tool to explore the pathway structure of metabolism. PMID:17608928

Objective To examine whether drawing is useful in the detection of problems of psychosocial adaptation in children and adolescents with type 1 diabetes (T1D) and in improving communication with health professionals. Methods We performed an exploratory descriptive study in 199 children and adolescents with T1D aged 4–13 years. The participants were asked to render a drawing on a suggested topic. The variables analyzed were related to the drawing and to clinical and sociodemographic data. Results Most participants showed evidence of having a well-balanced personality, but there were also signs of affective or psychosocial difficulties. Conclusion Drawing is a useful technique by which to identify children’s and adolescents’ feelings and possible problems in adapting to T1D, as well as to gain information directly from the children themselves. Future studies should delimit the possibilities of this technique in clinical practice in greater detail. PMID:23814467

[Purpose] To examine the effects of lumbopelvic sling and abdominal drawing-in exercises on the lung capacities of healthy subjects. [Subjects and Methods] Twenty-nine healthy subjects with no orthopedic history of the back were recruited. Subjects were randomly assigned to a experimental group and control group. Subjects were allocated to one of two groups; an experimental group that underwent lumbopelvic sling and abdominal drawing-in exercises and a control group that underwent treadmill and abdominal drawing-in exercises. Lung capacities were evaluated 4 weeks after exercises. [Results] The experimental group showed significant increments in EV, ERV, IRV, VT vs. pre-intervention results, and the control group showed significant increments in the EVC and IRV. Significant intergroup differences were observed in terms of post-training gains in EVC, IRV, and VT. [Conclusion] Combined application of lumbopelvic sling and abdominal drawing-in exercises were found to have a positive effect on lung capacity.

Projective drawings for assessing stress among subjects with medical symptoms compatible with sick building syndrome, and validation of a modified version of the Stress Load Index from the Drawing Personality Profile: a pilot study.

Runeson, Roma; Wahlstedt, Kurt; Norbäck, Dan

2007-02-01

It was hypothesized that subjects with medical symptoms would show more signs of stress in projective drawings. A Stress Load Index, including five signs of stress in drawings, was evaluated. A questionnaire with an instruction to draw "a person in the rain" was sent to a cohort of 195 subjects, and the drawings were analysed blindly for eight stress items. Men had a higher index than women (p < .05) and drew clouds more often (p < .05). Drawing of clouds was associated with headache (adjOR = 4.28; 95% CI 1.75; 11.68). Drawing of puddles was associated with ocular symptoms (adjOR = 3.22; 95% CI 1.38, 7.50), facial dermal symptoms (adjOR= 2.94; 95% CI 1.28, 6.81), and tiredness (adjOR = 2.44; 95% CI 1.05, 5.67). Drawing of long rain strokes was associated with nasal symptoms (adjOR = 2.28; 95% CI 1.05, 2.06) and headache (adjOR = 3.20; 95% CI 1.28, 8.05). Age and stress load were predictors of sick building syndrome symptoms (p < .05). In conclusion, a nonverbal projective drawing test detected sex differences which represent directions opposite to those with verbal methods. These need empirical assessment.

Introduction: In a population-based study of 1,912 community-dwelling persons of 45 years and older, we investigated the relation between age and fine motor skills using the Archimedes spiral-drawing test. Also, we studied the effect of brain volume on fine motor skills. Methods: Participants were required to trace a template of a spiral on an electronic drawing board. Clinical scores from this test were obtained by visual assessment of the drawings. Quantitative measures were objectively determined from the recorded data of the drawings. As tremor is known to occur increasingly with advancing age, we also rated drawings to assess presence of tremor. Results: We found presence of a tremor in 1.3% of the drawings. In the group without tremor, we found that older age was related to worse fine motor skills. Additionally, participants over the age of 75 showed increasing deviations from the template when drawing the spiral. Larger cerebral volume and smaller white matter lesion volume were related to better spiral-drawing performance, whereas cerebellar volume was not related to spiral-drawing performance. Conclusion: Older age is related to worse fine motor skills, which can be captured by clinical scoring or quantitative measures of the Archimedes spiral-drawing test. Persons with a tremor performed worse on almost all measures of the spiral-drawing test. Furthermore, larger cerebral volume is related to better fine motor skills. PMID:25309436

Background Engaging youth and incorporating their unique expertise into the research process is important when addressing issues related to their health. Visual Voices is an arts-based participatory data collection method designed to work together with young people and communities to collaboratively elicit, examine, and celebrate the perspectives of youth. Objectives To present a process for using the creative arts with young people as a participatory data collection method and to give examples of their perspectives on safety and violence. Methods Using the creative arts, this study examined and illustrates the perspectives of how community factors influence safety and violence. Visual Voices was conducted with a total of 22 African-American youth in two urban neighborhoods. This method included creative arts-based writing, drawing, and painting activities designed to yield culturally relevant data generated and explored by youth. Qualitative data were captured through the creative content of writings, drawings, and paintings created by the youths as well as transcripts from audio recorded group discussion. Data was analyzed for thematic content and triangulated across traditional and nontraditional mediums. Findings were interpreted with participants and shared publicly for further reflection and utilization. Conclusion The youth participants identified a range of issues related to community factors, community safety, and violence. Such topics included the role of schools and social networks within the community as safe places and corner stores and abandoned houses as unsafe places. Visual Voices is a creative research method that provides a unique opportunity for youth to generate a range of ideas through access to the multiple creative methods provided. It is an innovative process that generates rich and valuable data about topics of interest and the lived experiences of young community members. PMID:20097996

Nurses' clinical reasoning practices that support safe medication administration: An integrative review of the literature.

PubMed

Rohde, Emily; Domm, Elizabeth

2018-02-01

To review the current literature about nurses' clinical reasoning practices that support safe medication administration. The literature about medication administration frequently focuses on avoiding medication errors. Nurses' clinical reasoning used during medication administration to maintain medication safety receives less attention in the literature. As healthcare professionals, nurses work closely with patients, assessing and intervening to promote mediation safety prior to, during and after medication administration. They also provide discharge teaching about using medication safely. Nurses' clinical reasoning and practices that support medication safety are often invisible when the focus is medication errors avoidance. An integrative literature review was guided by Whittemore and Knafl's (Journal of Advanced Nursing, 5, 2005 and 546) five-stage review of the 11 articles that met review criteria. This review is modelled after Gaffney et al.'s (Journal of Clinical Nursing, 25, 2016 and 906) integrative review on medical error recovery. Health databases were accessed and systematically searched for research reporting nurses' clinical reasoning practices that supported safe medication administration. The level and quality of evidence of the included research articles were assessed using The Johns Hopkins Nursing Evidence-Based Practice Rating Scale©. Nurses have a central role in safe medication administration, including but not limited to risk awareness about the potential for medication errors. Nurses assess patients and their medication and use knowledge and clinical reasoning to administer medication safely. Results indicated nurses' use of clinical reasoning to maintain safe medication administration was inadequately articulated in 10 of 11 studies reviewed. Nurses are primarily responsible for safe medication administration. Nurses draw from their foundational knowledge of patient conditions and organisational processes and use clinical reasoning that supports safe medication practice. There was minimal evidence clearly articulating nurses' clinical reasoning used to support medication safety. This review focused on finding evidence of nurses' clinical reasoning that supported safe medication administration. © 2017 John Wiley & Sons Ltd.

2017-01-01

Purpose: In response to requests from physiotherapists for guidance on optimal stimulation of muscle using neuromuscular electrical stimulation (NMES), a review, synthesis, and extraction of key data from the literature was undertaken by six Canadian physical therapy (PT) educators, clinicians, and researchers in the field of electrophysical agents. The objective was to identify commonly treated conditions for which there was a substantial body of literature from which to draw conclusions regarding the effectiveness of NMES. Included studies had to apply NMES with visible and tetanic muscle contractions. Method: Four electronic databases (CINAHL, Embase, PUBMED, and SCOPUS) were searched for relevant literature published between database inceptions until May 2015. Additional articles were identified from bibliographies of the systematic reviews and from personal collections. Results: The extracted data were synthesized using a consensus process among the authors to provide recommendations for optimal stimulation parameters and application techniques to address muscle impairments associated with the following conditions: stroke (upper or lower extremity; both acute and chronic), anterior cruciate ligament reconstruction, patellofemoral pain syndrome, knee osteoarthritis, and total knee arthroplasty as well as critical illness and advanced disease states. Summaries of key details from each study incorporated into the review were also developed. The final sections of the article outline the recommended terminology for describing practice using electrical currents and provide tips for safe and effective clinical practice using NMES. Conclusion: This article provides physiotherapists with a resource to enable evidence-informed, effective use of NMES for PT practice. PMID:29162949

Background. Perseveration has been observed in a number of behavioural contexts, including speaking, writing, and drawing. However, no previous report describes patients who show perseveration only for drawing a human figure. Objective. The present report describes a group of patients who show body awareness-related cognitive impairment during a human figure drawing task, a different presentation from previously described neuropsychological cases. Methods. Participants were 15 patients who had a frontal lobe brain tumour around the insula cortex of the right hemisphere and had subsequently undergone a neurosurgical resective operation. Participants were asked to draw a human figure in both “hands-down” and “hands-up” configurations. Results. Eight of the 15 patients drew a human figure with six fingers during the “hands-up” and the “hands-down” human figure drawing tasks (one patient drew eight fingers). A statistical analysis of potential lesion areas revealed damage to the right anterior frontal insula and operculum in this group of patients relative to the five-finger drawing group. Conclusions. Our findings reveal a newly described neuropsychological phenomenon that could reflect impairment in attention directed towards body representations. PMID:24876665

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

Summary Introduction: Juvenile nasopharyngeal angiofibroma is a rare, highly vascular, and histologically benign tumor, generally observed in male adolescents. It shows very aggressive behavior due to local invasiveness and is associated with various symptoms. Juvenile nasopharyngeal angiofibroma originates in the sphenopalatine forame, causing epistaxes and nasal obstruction. Objective: To retrospectively describe our experience in the diagnosis and treatment of patients with juvenile nasopharyngeal angiofibroma. Scientific drawing: Retrospective, descriptive study conducted after approval from the Ethics Committee of the Federal University of Sergipe (protocol 0114.0.107.000 -11). Methods: We analyzed findings in 20 patients who underwent surgery between 2004 and 2011. Factors analyzed include patient age and gender, symptoms, stages, treatment, length of surgery, intraoperatory bleeding, postoperative need for nasal tampons, hospitalization time, complications, and tumor recurrence. Results: Patients were aged 10–29 years. All patients were treated surgically, including 17 who underwent endoscopic surgery. The mean operation time was 120 min, and the mean bleeding volume was 300 mL. Seventeen patients required clamping of the external carotids and tumor embolization. Conclusion: Endoscopic surgery alone or with other conventional techniques was safe for the treatment of angiofibromas of different stages. PMID:25991988

What's cooking with garlic: is this complementary and alternative medicine for hypertension?

To define complementary and alternative medicine (CAM); describe one type of CAM, garlic (Allium sativum L); and discuss its effects on blood pressure as a treatment for hypertension. Literature review from professional journals, abstracts, natural therapy books, and the World Wide Web (Internet). Information from the following professional organizations and agencies: The World Health Organization, Agency of Healthcare Research and Quality, National Cancer Institute, National Center for Complementary and Alternative Medicine, American Botanical Council, and Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure. Garlic is widely used throughout the world as a CAM. It is one of the most popular herbal products sold in the United States. However, while some studies have shown small positive effects in reducing blood pressure, there are insufficient scientific data to draw conclusions regarding its efficacy on clinical blood pressure outcomes. Thus, healthcare providers should be cautious in recommending this herbal product as an antihypertensive CAM. CAMs may be used by clients for a variety of conditions including hypertension. Healthcare providers must be cognizant of the use, efficacy, adverse affects, and scientific evidence concerning CAM in order to provide safe and effective practice as well as appropriate and accurate information to their clients.

Drawing conclusions: a re-examination of empirical and conceptual bases for psychological evaluation of children from their drawings.

Thomas, G V; Jolley, R P

1998-05-01

Although consideration of children's art work (usually drawings) in clinical investigations of children referred to psychologists is fairly common, there is little evidence for the reliability and validity of such assessments. We consider a variety of possible mechanisms which could operate to influence the characteristics of children's drawings, and review the evidence that such mechanisms operate to allow meaningful psychological evaluations of children from their drawings. The problem for making a reliable interpretation of the significance of a drawing is that a given feature could plausibly support several very different interpretations, depending which of many possible processes was active or dominant in the production of the drawing. Evidence from studies of clinical populations and experimental studies with non-selected samples are reviewed in the light of these possibilities. The review indicates that drawings are inaccurate and unreliable as personality or state assessments but can be influenced by children's emotional attitudes towards the topics depicted. The form of that expression, however, may be personal and idiosyncratic. Analogue studies of these effects undertaken with non-clinical samples under controlled conditions have produced mixed results. At best the reported effects are small. Children's drawings on their own are too complexly determined and inherently ambiguous to be reliable sole indicators of the emotional experiences of the children who drew them. Further research is needed to establish the extent to which such drawings can usefully facilitate assessment of children by other means or provide useful support as one of several converging lines of evidence.

Background Tree-drawing test is used as a projective psychological test that expresses the abnormal internal experience in patients with schizophrenia (SZ). Despite the widely accepted view that the cognitive function is involved in characteristic tree-drawing in patients with SZ, no study has psychophysiologically examined it. The present study aimed to investigate the involvement of cognitive function during tree-drawing in patients with SZ. For that purpose, we evaluated the brain function in patients with SZ during a tree-drawing task by using near-infrared spectroscopy (NIRS) and compared them with those in healthy controls. Patients and methods The subjects were 28 healthy controls and 28 patients with SZ. Changes in the oxygenated hemoglobin ([oxy-Hb]) concentration in both the groups during the task of drawing a tree imagined freely (free-drawing task) and the task of copying an illustration of a tree (copying task) were measured by using NIRS. Results Because of the difference between the task conditions, [oxy-Hb] levels in controls during the free-drawing task were higher than that during the copying task at the bilateral frontal pole regions and left inferior frontal region. Because of the difference between the groups, [oxy-Hb] levels at the left middle frontal region, bilateral inferior frontal regions, bilateral inferior parietal regions, and left superior temporal region during the free-drawing task in patients were lower than that in controls. Conclusion [oxy-Hb] during the tree-drawing task in patients with SZ was lower than that in healthy controls. Our results suggest that brain dysfunction in patients with SZ might be associated with their tree-drawing. PMID:29719398

Objectives: To examine the extensive research undertaken by the tobacco industry over the past 25 years toward development of a fire safe cigarette. Methods: Research was conducted through a web based search of internal tobacco industry documents made publicly available through the 1998 Master Settlement Agreement. Results: The documents reveal that the tobacco industry produced a fire safe cigarette years ago, but failed to put it on the market. These findings contradict public industry claims that denied the technical feasibility and commercial acceptability of fire safe cigarettes. Internal documents also reveal a decades long, coordinated political strategy used to block proposed legislation and obfuscate the fire safe issue. Conclusions: Federal legislation mandating fire safe cigarettes is needed. PMID:12432160

Phlebotomy, a commonly performed medical procedure in healthcare, is essential for disease diagnosis and patient management. However, poorly performed phlebotomy can compromise patient safety, healthcare worker (HCW) safety, and specimen quality. We carried out a study between June and July 2010 to assess knowledge, quality and safety of phlebotomy before implementation of a public-private partnership between Becton, Dickinson and Company and the US President's Emergency Plan for AIDS Relief. This was a cross-sectional observational study in 8 healthcare facilities within 4 regions of Kenya. HCWs were observed conducting venous and capillary blood collections, and pre- and posttests were offered during HCW training. Of 283 blood samples obtained, 194 were venous draws conducted by 72 HCWs and 89 were capillary draws performed by 33 HCWs. Based on 12 preset quality-associated criteria, none of the 194 observed phlebotomies met the standard. In total, 91 HCWs were trained in phlebotomy. The mean knowledge increase between pre- and posttraining test was 41%, ranging from 39% to 45% (95% confidence interval, 29.3%-53.5%;P< .001). Inadequate knowledge and imperfect phlebotomy procedures were noted. This formed the basis for the safe phlebotomy partnership to address these deficiencies. To ensure sustainability, safe phlebotomy practices were integrated into preservice training. Published by Oxford University Press for the Infectious Diseases Society of America 2016.

2017-01-01

Background: The purpose of this study was to assess the association between safe sex self-efficacy and safe-sex practice in a Southern college setting. Methods: Multivariable logistic regression models were used to examine the association between safe sex self-efficacy in four domains (mechanics, partner disapproval, assertiveness, intoxicants) and safe sex practice (outcome variable). Results: For every 1-unit increase in the composite condom use self-efficacy score, there was an 8% increase in the odds of being beyond the median safe-sex practice score (odds ration [OR]: 1.08, 95% CI: 1.02-1.15). Additionally, for every 1-unit increase in intoxicants self-efficacy score, there was a 31% increase in the odds of being beyond the median safe-sex practice score (OR: 1.31, 95% CI: 1.08-1.58). Conclusion: A greater degree of safe-sex self-efficacy is associated with increased odds of safe-sex practice. These findings are informative for the development of targeted approaches to foster safe-sex behavior in Southern US colleges. PMID:28326287

2012-03-01

As electroconvulsive therapy (ECT) requires general anesthesia and is associated with both cognitive and non-cognitive side effects, careful consideration must be given to the safety aspects of providing ECT on an outpatient basis. Drawing upon published literature and their clinical experience administering outpatient ECT, the authors propose best practices for safely providing ECT to outpatients. They review criteria for selecting patients for outpatient ECT as well as treatment and programmatic issues. The authors highlight the importance of educating referring clinicians as well as patients and their families about factors involved in the safe delivery of ECT for outpatients. Fiscal considerations and the drive toward reduced length of stay are prompting insurers and caregivers to choose outpatient over inpatient ECT. For each patient, such a choice merits a careful analysis of the risks of outpatient ECT, as well as the implementation of measures to ensure patient safety.

AIM: To evaluate the efficacy of drawings as a projective measure of pain and distress in children undergoing dental extractions. METHODS: Children in the age range of 4-13 years with existence of untreatable caries or over-retained primary teeth, indicated for extractions were included. Pain was assessed using one behavioral [faces, legs, activity, cry and consolability (FLACC)] scale; and a self report measure; faces pain scale-revised (FPS-R), at two points of time, after completion of local anesthetic administration and after extraction. The general behavior of children was assessed with Wright’s modification of Frankl rating scale. At the end of the session, children were instructed to represent, themselves along with the dentist and their experiences of the dental treatment through drawing. The drawings were scored utilizing Child drawing: Hospital scale (CD: H) manual and correlated with FLACC, FPS-R and Frankl using Pearson correlation test. RESULTS: A positive correlation, though statistically not significant, was observed between CD: H scores and all other considered parameters (Frankl, FPS-R and FLACC) in the present study. CONCLUSION: Drawings could not act as surrogate measure of child’s pain; however, they acted as a narrative of his/her experiences and reflection of inner emotions. Hence, drawings can be used as an additional dental armamentarium. PMID:26862509

2015-09-22

Infectious uveitis is a significant cause of blindness in South Africa, especially among HIV-infected individuals. The visual outcome of uveitis depends on early clinical and laboratory diagnosis to guide therapeutic intervention. Analyses of aqueous humor, obtained by anterior chamber paracentesis, directs the differential diagnosis in infectious uveitis. However, although safe and potentially cost-effective, diagnostic anterior chamber paracentesis is not common practice in ophthalmic care across Africa. We seek to draw attention to this important procedure that could improve the diagnosis and prognosis of infectious uveitis.

[Purpose] This study examined the clinical usefulness of the clock drawing test applying Rasch analysis for predicting the level of cognitive impairment. [Subjects and Methods] A total of 187 stroke patients with cognitive impairment were enrolled in this study. The 187 patients were evaluated by the clock drawing test developed through Rasch analysis along with the mini-mental state examination of cognitive evaluation tool. An analysis of the variance was performed to examine the significance of the mini-mental state examination and the clock drawing test according to the general characteristics of the subjects. Receiver operating characteristic analysis was performed to determine the cutoff point for cognitive impairment and to calculate the sensitivity and specificity values. [Results] The results of comparison of the clock drawing test with the mini-mental state showed significant differences in according to gender, age, education, and affected side. A total CDT of 10.5, which was selected as the cutoff point to identify cognitive impairement, showed a sensitivity, specificity, Youden index, positive predictive, and negative predicive values of 86.4%, 91.5%, 0.8, 95%, and 88.2%. [Conclusion] The clock drawing test is believed to be useful in assessments and interventions based on its excellent ability to identify cognitive disorders.

Background Cleft lip (CL) and cleft palate (CP) are among the most common congenital deformities of the head and neck. They are associated with many problems, physical and psychological. We describe 171 children and adolescents with CL/CP from 22 countries who were asked to draw their faces in a self-image perception drawing 2 hours before surgery to repair their deformities. Methods The aim of the study was to explore whether children and adolescents with CL and CP perceived themselves as deformed when given the opportunity to draw their faces before surgery to repair their deformities. Children were asked to lie down on a large piece of paper to have their body outline traced. Subsequently, the children were asked to draw their faces within the outline. Results All of the children included in this study drew their faces with normal mouths. Conclusion None of the 171 patients with CL/CP drew their deformity when asked to draw their faces; the reasons are not clear. The children may have wanted to compensate for their disability with the constructive use of fantasy as they anticipated the surgery to repair their CL/CP. An additional hypothesis is that the children felt the need to draw an image that they knew represented their parents' desires. PMID:23789006

Duchenne Muscular Dystrophy (DMD) is caused by mutations in the dystrophin gene leading to dystrophin deficiency, muscle fiber degeneration and progressive fibrotic replacement of muscles. Givinostat, a histone deacetylase (HDAC) inhibitor, significantly reduced fibrosis and promoted compensatory muscle regeneration in mdx mice. This study was conducted to evaluate whether the beneficial histological effects of Givinostat could be extended to DMD boys. Twenty ambulant DMD boys aged 7 to <11 years on stable corticosteroid treatment were enrolled in the study and treated for ≥12 months with Givinostat. A muscle biopsy was collected at the beginning and at the end of treatment to evaluate the amount of muscle and fibrotic tissue. Histological effects were the primary objectives of the study. Treatment with Givinostat significantly increased the fraction of muscle tissue in the biopsies and reduced the amount of fibrotic tissue. It also substantially reduced tissue necrosis and fatty replacement. Overall the drug was safe and tolerated. Improvement in functional tests was not observed in this study, but the sample size of the study was not sufficient to draw definitive conclusions. This study showed that treatment with Givinostat for more than 1 year significantly counteracted histological disease progression in ambulant DMD boys aged 7 to 10 years.

Objective Drawing on interviews with home care clients and their family caregivers, we sought to understand how these individuals conceptualize safety in the provision and receipt of home care, how they promote safety in the home space and how their safety concerns differ from those of home support workers. Design In-depth, semi-structured interviews were conducted with clients and family caregivers. The analysis included topic and analytical coding of participants' verbatim accounts. Setting Interviews were completed in British Columbia, Canada. Participants Totally 82 clients and 55 caregivers participated. Results Clients and family caregivers identified three types of safety concerns: physical, spatial and interpersonal. These concerns are largely multi-dimensional and intersectional. We present a conceptual model of client and caregiver safety concerns. We also examine the factors that intensify and mitigate safety concerns in the home. Conclusions In spite of safety concerns, clients and family caregivers overwhelmingly prefer to receive care in the home setting. Spatial and physical concerns are the most salient. The financial burden of creating a safe care space should not be the client's alone to bear. The conceptualization and promotion of safety in home care must recognize the roles, responsibilities and perspectives of all of the actors involved, including workers, clients and their caregivers.

Nanotechnology is a promising area in industry with a broad range of applications including in the agri-food sector. Several studies have investigated the potential benefits deriving from use of nanomaterials in the context of the whole food chain drawing scenarios of benefits but also potential for concerns. Among the agri-food sector, animal production has potential for nanomaterial application but also for safety concerns due to the possibility of nanomaterial accumulation along the farm-to-fork path. Scope and Approach: The aim of this work was to define the state of the art of nanomaterial applications in the animal production sector by assessing data belonging to recently publishes studies. To do this, a qualitative synthesis approach was applied to build a fit-for-purpose framework and to summarise relevant themes in the context of effectiveness, feasibility and health concerns. Key findings and conclusions: Nanomaterials have potential for use in a wide range of applications from feed production and farming to food packaging, including several detection tools designed for the benefit of consumer protection. The current high degree of variability in nanomaterials tested and in study designs impairs external validation of research results. Further research is required to clearly define which safe nanomaterial applications have the potential to reach the market.

Pharmacoepidemiology for nephrologists: do proton pump inhibitors cause chronic kidney disease?

Tomlinson, Laurie A.; Fogarty, Damian G.; Douglas, Ian; Nitsch, Dorothea

2017-01-01

Abstract Pharmacoepidemiology studies are increasingly used for research into safe prescribing in chronic kidney disease (CKD). Typically, patients prescribed a drug are compared with patients who are not on the drug and outcomes are compared to draw conclusions about the drug effects. This review article aims to provide the reader with a framework to critically appraise such research. A key concern in pharmacoepidemiology studies is confounding, in that patients who have worse health status are prescribed more drugs or different agents and their worse outcomes are attributed to the drugs not the health status. It may be challenging to adjust for this using statistical methods unless a comparison group with a similar health status but who are prescribed a different (comparison) drug(s) is identified. Another challenge in pharmacoepidemiology is outcome misclassification, as people who are more ill engage more often with the health service, leading to earlier diagnosis in people who are frequent attenders. Finally, using replication cohorts with the same methodology in the same type of health system does not ensure that findings are more robust. We use two recent papers that investigated the association of proton pump inhibitor drugs with CKD as a device to review the main pitfalls of pharmacoepidemiology studies and how to attempt to mitigate against potential biases that can occur.

In recent years, all-male cultures of Nile tilapia (Oreochromis niloticus) have been the most preferred mode of production in aquaculture industry. All-male individuals achieve higher somatic growth rate and shut high energy losses associated with gonadal development and reproduction. The economic advantages of culturing all-male tilapia have led to the development of procedures for producing unisex cultures, using 17α-methyltestosterone (MT). Despite widespread use of the MT in tilapia farming, the implications of hormone treatment in relation to human health and the environment have raised a number of concerns in the scientific community. In this review, the hormonal application processes, economic and ecological significance of MT, food safety and residual MT, comparative uses of steroids in aquaculture, animal husbandry, and medicine have been briefly reviewed for regulatory guidelines, and finally, future research perspectives have been addressed. The review can be used as policy-making guidelines in aquaculture framework development as can be emphasized in African continent, among others. The most important conclusion to draw is that the quantity of MT used in conventional practice is large compared to the actual dose required for sex reversal, fish produced are safe for human consumptions, and the environmental hazards should be further emphasized.

Safe haven laws as crime control theater.

PubMed

Hammond, Michelle; Miller, Monica K; Griffin, Timothy

2010-07-01

This article examines safe haven laws, which allow parents to legally abandon their infants. The main objective is to determine whether safe haven laws fit the criteria of crime control theater, a term used to describe public policies that produce the appearance, but not the effect, of crime control, and as such are essentially socially constructed "solutions" to socially constructed crime "problems." The analysis will apply the principles of crime control theater to safe haven laws. Specifically, the term crime control theater applies to laws that are reactionary responses to perceived criminal threats and are often widely supported as a way to address the crime in question. Such laws are attractive because they appeal to mythic narratives (i.e., saving an innocent child from a predator); however they are likely ineffective due to the complexity of the crime. These laws can have deleterious effects when policymakers make false claims of success and stunt public discourse (e.g., drawing attention away from more frequent and preventable crimes). This analysis applies these criteria to safe haven laws to determine whether such laws can be classified as crime control theater. Many qualities inherent to crime control theater are present in safe haven laws. For example, the laws are highly publicized, their intentions lack moral ambiguity, rare cases of success legitimize law enforcement and other agencies, and they appeal to the public sense of responsibility in preventing crime. Yet the goal of saving infant lives may be unattainable. These qualities make the effectiveness of the laws questionable and suggest they may be counterproductive. This analysis determined that safe haven laws are socially constructed solutions to the socially constructed problem of child abandonment. Safe haven laws are appropriately classified as crime control theater. It is imperative that further research be conducted to examine the effectiveness and collateral effects of safe haven laws. Longitudinal studies and a nationwide database to better determine the effectiveness of safe haven laws are suggested. It is also crucial that agencies implementing SHLs closely monitor the reasons parents abandon their children, and adopt policies that re-focus the attention safe haven laws receive to address more frequent causes of harm to infants.

Are nursing students safe when choosing gluteal intramuscular injection locations?

PubMed

Cornwall, J

2011-01-01

Nurses are required to perform gluteal intramuscular (IM) injections in practice. There are dangers associated with erroneous performance of this task, particularly with dorsogluteal injections. Knowledge regarding safe injection practice is therefore vital for nursing students. Fifty-eight second year students at a New Zealand Nursing School were given schematic drawings of the posterior and lateral aspects of the gluteal region. They were asked to mark and justify the safest location for gluteal IM injections. Fifty-seven students marked the dorsal schematic and one the lateral, with 38 (66.7%) marking in the upper outer quadrant (UOQ). Twenty indicating the UOQ (52.6%) wrote 'sciatic' or 'nerve' in justifying their location. Nineteen (33.3%) marked a location outside the UOQ; nine (47.4%) of these mentioned 'sciatic' or 'nerve' as reasons for injection safety. Overall, 50% of students mentioned 'sciatic' or 'nerve' in justifying the safety of their chosen injection location. Results suggest some second year nursing students do not understand safe gluteal IM injection locations and rationale. Current teaching practices and IM injection techniques could be revisited to prepare students more effectively; this may help prevent pathologies arising from this procedure.

Culture, perception, and artistic visualization: a comparative study of children's drawings in three Siberian cultural groups.

PubMed

Istomin, Kirill V; Panáková, Jaroslava; Heady, Patrick

2014-01-01

In a study of three indigenous and non-indigenous cultural groups in northwestern and northeastern Siberia, framed line tests and a landscape drawing task were used to examine the hypotheses that test-based assessments of context sensitivity and independence are correlated with the amount of contextual information contained in drawings, and with the order in which the focal and background objects are drawn. The results supported these hypotheses, and inspection of the regression relationships suggested that the intergroup variations in test performance were likely to result from differences in the attention accorded to contextual information, as revealed by the drawings. Social and environmental explanations for the group differences in context sensitivity are also discussed. The conclusions support the argument that cultural differences in artistic styles and perceptual tests reflect the same underlying perceptual tendencies, and they are consistent with the argument that these tendencies reflect corresponding differences in patterns of social and environmental interaction.

A taxonomy of nursing care organization models in hospitals

PubMed Central

2012-01-01

Background Over the last decades, converging forces in hospital care, including cost-containment policies, rising healthcare demands and nursing shortages, have driven the search for new operational models of nursing care delivery that maximize the use of available nursing resources while ensuring safe, high-quality care. Little is known, however, about the distinctive features of these emergent nursing care models. This article contributes to filling this gap by presenting a theoretically and empirically grounded taxonomy of nursing care organization models in the context of acute care units in Quebec and comparing their distinctive features. Methods This study was based on a survey of 22 medical units in 11 acute care facilities in Quebec. Data collection methods included questionnaire, interviews, focus groups and administrative data census. The analytical procedures consisted of first generating unit profiles based on qualitative and quantitative data collected at the unit level, then applying hierarchical cluster analysis to the units’ profile data. Results The study identified four models of nursing care organization: two professional models that draw mainly on registered nurses as professionals to deliver nursing services and reflect stronger support to nurses’ professional practice, and two functional models that draw more significantly on licensed practical nurses (LPNs) and assistive staff (orderlies) to deliver nursing services and are characterized by registered nurses’ perceptions that the practice environment is less supportive of their professional work. Conclusions This study showed that medical units in acute care hospitals exhibit diverse staff mixes, patterns of skill use, work environment design, and support for innovation. The four models reflect not only distinct approaches to dealing with the numerous constraints in the nursing care environment, but also different degrees of approximations to an “ideal” nursing professional practice model described by some leaders in the contemporary nursing literature. While the two professional models appear closer to this ideal, the two functional models are farther removed. PMID:22929127

Restoration of paper artworks with microemulsions confined in hydrogels for safe and efficient removal of adhesive tapes.

2018-05-21

The presence of pressure-sensitive tapes (PSTs) on paper artworks, either fortuitous or specifically applied for conservation purposes, is one of the most frequent and difficult issues encountered during restoration. Aged PSTs can damage or disfigure artworks, compromising structural integrity, readability, and enjoyment. Current procedures are often inherently hazardous for artistic media and paper support. Challenged by the necessity to remove PSTs from a contemporary and an ancient drawing (20th century, by artists da Silva and Hayter, and a 16th century drawing of one figure from the Sistine Chapel by Michelangelo), we addressed this issue from a physicochemical perspective, leveraging colloid and interface science. After a characterization of the specific PSTs present on the artifact, we selected a highly water-retentive hydrogel as the host of 23% wt/wt of "green" organic solvents uniformly dispersed within the gel in the form of nanosized droplets. The double confinement of the organic solvent in the nanodroplets and into the gel network promotes a tailored, controlled removal of PSTs of different natures, with virtually no interaction with the solvent-sensitive artwork. This noninvasive procedure allows complete retrieval of artwork readability. For instance, in the ancient drawing, the PST totally concealed the inscription, " di mano di Michelangelo " ("from Michelangelo's hand"), a possibly false attribution hidden by a collector, which is now perfectly visible and whose origin is currently under investigation. Remarkably, the same methodology was successful for the removal of aged PST adhesive penetrated inside paper fibers of a drawing from the celebrated artist Lucio Fontana.

2017-02-01

This cross-sectional study explored students' conceptions of science learning via drawing analysis. A total of 906 Taiwanese students in 4th, 6th, 8th, 10th, and 12th grade were asked to use drawing to illustrate how they conceptualise science learning. Students' drawings were analysed using a coding checklist to determine the presence or absence of specified attributes. Data analysis showed that the majority of students pictured science learning as school-based, involving certain types of experiment or teacher lecturing. In addition, notable cross-sectional differences were found in the 'Activity' and 'Emotions and attitudes' categories in students' drawings. Three major findings were made: (1) lower grade level students conceptualised science learning with a didactic approach, while higher graders might possess a quantitative view of science learning (i.e. how much is learned, not how well it is learned), (2) students' positive and negative emotions and attitudes toward science learning reversed around middle school, and (3) female students expressed significantly more positive emotions and attitudes than their male counterparts. In conclusion, higher graders' unfruitful conceptions of science learning warrant educators' attention. Moreover, further investigation of girls' more positive emotions and attitudes found in this study is needed.

A universal test for gravitational decoherence

PubMed Central

Pfister, C.; Kaniewski, J.; Tomamichel, M.; Mantri, A.; Schmucker, R.; McMahon, N.; Milburn, G.; Wehner, S.

2016-01-01

Quantum mechanics and the theory of gravity are presently not compatible. A particular question is whether gravity causes decoherence. Several models for gravitational decoherence have been proposed, not all of which can be described quantum mechanically. Since quantum mechanics may need to be modified, one may question the use of quantum mechanics as a calculational tool to draw conclusions from the data of experiments concerning gravity. Here we propose a general method to estimate gravitational decoherence in an experiment that allows us to draw conclusions in any physical theory where the no-signalling principle holds, even if quantum mechanics needs to be modified. As an example, we propose a concrete experiment using optomechanics. Our work raises the interesting question whether other properties of nature could similarly be established from experimental observations alone—that is, without already having a rather well-formed theory of nature to make sense of experimental data.

Analyzing prospective teachers' images of scientists using positive, negative and stereotypical images of scientists

2013-04-01

Background and purpose : This study details the use of a conceptual framework to analyze prospective teachers' images of scientists to reveal their context-specific conceptions of scientists. The conceptual framework consists of context-specific conceptions related to positive, stereotypical and negative images of scientists as detailed in the literature on the images, role and work of scientists. Sample, design and method : One hundred and ninety-six drawings of scientists, generated by prospective teachers, were analyzed using the Draw-A-Scientist-Test Checklist (DAST-C), a binary linear regression and the conceptual framework. Results : The results of the binary linear regression analysis revealed a statistically significant difference for two DAST-C elements: ethnicity differences with regard to drawing a scientist who was Caucasian and gender differences for indications of danger. Analysis using the conceptual framework helped to categorize the same drawings into positive, stereotypical, negative and composite images of a scientist. Conclusions : The conceptual framework revealed that drawings were focused on the physical appearance of the scientist, and to a lesser extent on the equipment, location and science-related practices that provided the context of a scientist's role and work. Implications for teacher educators include the need to understand that there is a need to provide tools, like the conceptual framework used in this study, to help prospective teachers to confront and engage with their multidimensional perspectives of scientists in light of the current trends on perceiving and valuing scientists. In addition, teacher educators need to use the conceptual framework, which yields qualitative perspectives about drawings, together with the DAST-C, which yields quantitative measure for drawings, to help prospective teachers to gain a holistic outlook on their drawings of scientists.

Postpartum Hemorrhage Resulting from Pelvic Pseudoaneurysm: A Retrospective Analysis of 588 Consecutive Cases Treated by Arterial Embolization

Objective: This study was designed to determine the incidence of arterial pseudoaneurysm in patients presenting with postpartum hemorrhage (PPH), to analyze the angiographic characteristics of pseudoaneurysms that cause PPH, and to evaluate the effectiveness of pelvic arterial embolization for the treatment of this condition.Study designEighteen women with pelvic arterial pseudoaneurysm were retrieved from a series of 588 consecutive patients with PPH treated by arterial embolization. Clinical files, angiographic examinations, and procedure details were reviewed. Results: The incidence of pseudoaneurysm was 3.06 % (18/588; 95 % confidence interval (CI): 1.82-4.8 %). A total of 20 pseudoaneurysms were found; 15/20 (75 %)more » were located on the uterine arteries. Angiography revealed extravasation of contrast material from pseudoaneurysm indicating rupture in 9 of 18 (50 %) patients. Arterial embolization was performed using gelatin sponge alone in 12 of 18 (67 %) patients or in association with metallic coils in 5 of 18 (28 %) patients or n-butyl-2-cyanoacrylate in 1 of 18 (6 %) patients. Arterial embolization allowed controlling the bleeding in all patients after one or two embolization sessions in 17 of 18 (94 %) and 1 of 18 patients (6 %) respectively, without complications, obviating the need for further surgery. Conclusions: Pseudoaneurysm is rarely associated with PPH. Arterial embolization is an effective and safe procedure for the treatment of PPH due to uterine or vaginal artery pseudoaneurysm. Our results suggest that gelatin sponge is effective for the treatment of ruptured pseudoaneurysms, although we agree that our series does not contain sufficient material to allow drawing definitive conclusions with respect to the most effective embolic material.« less

Supplementation with Omega-3 Fatty Acids in Psychiatric Disorders: A Review of Literature Data

PubMed Central

Bozzatello, Paola; Brignolo, Elena; De Grandi, Elisa; Bellino, Silvio

2016-01-01

A new application for omega-3 fatty acids has recently emerged, concerning the treatment of several mental disorders. This indication is supported by data of neurobiological research, as highly unsaturated fatty acids (HUFAs) are highly concentrated in neural phospholipids and are important components of the neuronal cell membrane. They modulate the mechanisms of brain cell signaling, including the dopaminergic and serotonergic pathways. The aim of this review is to provide a complete and updated account of the empirical evidence of the efficacy and safety that are currently available for omega-3 fatty acids in the treatment of psychiatric disorders. The main evidence for the effectiveness of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) has been obtained in mood disorders, in particular in the treatment of depressive symptoms in unipolar and bipolar depression. There is some evidence to support the use of omega-3 fatty acids in the treatment of conditions characterized by a high level of impulsivity and aggression and borderline personality disorders. In patients with attention deficit hyperactivity disorder, small-to-modest effects of omega-3 HUFAs have been found. The most promising results have been reported by studies using high doses of EPA or the association of omega-3 and omega-6 fatty acids. In schizophrenia, current data are not conclusive and do not allow us either to refuse or support the indication of omega-3 fatty acids. For the remaining psychiatric disturbances, including autism spectrum disorders, anxiety disorders, obsessive-compulsive disorder, eating disorders and substance use disorder, the data are too scarce to draw any conclusion. Concerning tolerability, several studies concluded that omega-3 can be considered safe and well tolerated at doses up to 5 g/day. PMID:27472373

International clinical experiences are increasingly popular among medical students, residents, fellows, and practitioners. Adequate pre-departure training is an integral part of a meaningful, productive, and safe international experience. At Johns Hopkins University School of Medicine, we have developed a pre-departure handbook to assist practitioners in preparing for global health work. The handbook draws from current global health education literature, existing handbooks, and expert experiences, and includes information about logistical and cultural preparations. While a pre-departure handbook cannot serve as a substitute for a comprehensive pre-departure training program, it can be a useful introduction to the pre-departure process.

Schools and Disasters: Safety and Mental Health Assessment and Interventions for Children.

Lai, Betty S; Esnard, Ann-Margaret; Lowe, Sarah R; Peek, Lori

2016-12-01

This article draws on experiences and lessons from global disasters and utilizes the United Nations Comprehensive School Safety Framework to highlight the necessary role of safe schools in protecting children, as well as adult staff, from the immediate threats and long-term implications of disasters. Specifically, we focus on three well-established pillars of school safety: Pillar I: Safe Learning Facilities; Pillar II: Disaster Management; and Pillar III: Risk Reduction and Resilience Education. In addition, we propose a potential fourth pillar, which underscores the function of schools in postdisaster mental health assessment and intervention for children. We argue that schools offer a central location and trusted institutional space for mental health assessment and intervention after disasters. We also examine the important linkages between schools, child mental health, and household and family recovery. We conclude with recommendations for filling gaps in research and practice related to ensuring the safety of schools and the associated health and well-being of children in the face of future disasters.

In Canada, cultural safety (CS) is emerging as a theoretical and practice lens to orient health care services to meet the needs of Aboriginal people. Evidence suggests Aboriginal peoples' encounters with health care are commonly negative, and there is concern that these experiences can contribute to further adverse health outcomes. In this article, we report findings based on participatory action research drawing on Indigenous methods. Our project goal was to interrogate practices within one hospital to see whether and how CS for Aboriginal patients could be improved. Interviews with Aboriginal patients who had accessed hospital services were conducted, and responses were collated into narrative summaries. Using interlocking analysis, findings revealed a number of processes operating to produce adverse health outcomes. One significant outcome is the production of structural violence that reproduces experiences of institutional trauma. Positive culturally safe experiences, although less frequently reported, were described as interpersonal interactions with feelings visibility and therefore, treatment as a "human being." © The Author(s) 2015.

“Playing the Numbers Game”: Evidence-based Advocacy and the Technocratic Narrowing of the Safe Motherhood Initiative

PubMed Central

Storeng, Katerini T; Béhague, Dominique P

2014-01-01

Based on an ethnography of the international Safe Motherhood Initiative (SMI), this article charts the rise of evidence-based advocacy (EBA), a term global-level maternal health advocates have used to indicate the use of scientific evidence to bolster the SMI's authority in the global health arena. EBA represents a shift in the SMI's priorities and tactics over the past two decades, from a call to promote poor women's health on the grounds of feminism and social justice (entailing broad-scale action) to the enumeration of much more narrowly defined practices to avert maternal deaths whose outcomes and cost effectiveness can be measured and evaluated. Though linked to the growth of an audit- and business-oriented ethos, we draw from anthropological theory of global forms to argue that EBA—or “playing the numbers game”—profoundly affects nearly every facet of evidence production, bringing about ambivalent reactions and a contested technocratic narrowing of the SMI's policy agenda.

Spreading the Word on Safety

NASA Technical Reports Server (NTRS)

2004-01-01

Beginning with the Apollo Program in the early 1960s, the NASA White Sands Test Facility (WSTF) has supported every U.S. human exploration space flight program to date. Located in Las Cruces, New Mexico, WSTF is part of Johnson Space Center. The facility's primary mission is to provide the expertise and infrastructure to test and evaluate spacecraft materials, components, and rocket propulsion systems to enable the safe human exploration and utilization of space. WSTF stores, tests, and disposes of Space Shuttle and International Space Station propellants. Since aerospace fluids can have harmful reactions with the construction materials of the systems containing them, a major component of WSTF's work is the study of propellants and hazardous materials. WSTF has a wide variety of resources to draw upon in assessing the fire, explosion, compatibility, and safety hazards of these fluids, which include hydrogen, oxygen, hydrazine fuels, and nitrogen tetroxide. In addition to developing new test methods, WSTF has created technical manuals and training courses for the safe use of aerospace fluids.

A Formal Model of Partitioning for Integrated Modular Avionics

NASA Technical Reports Server (NTRS)

DiVito, Ben L.

1998-01-01

The aviation industry is gradually moving toward the use of integrated modular avionics (IMA) for civilian transport aircraft. An important concern for IMA is ensuring that applications are safely partitioned so they cannot interfere with one another. We have investigated the problem of ensuring safe partitioning and logical non-interference among separate applications running on a shared Avionics Computer Resource (ACR). This research was performed in the context of ongoing standardization efforts, in particular, the work of RTCA committee SC-182, and the recently completed ARINC 653 application executive (APEX) interface standard. We have developed a formal model of partitioning suitable for evaluating the design of an ACR. The model draws from the mathematical modeling techniques developed by the computer security community. This report presents a formulation of partitioning requirements expressed first using conventional mathematical notation, then formalized using the language of SRI'S Prototype Verification System (PVS). The approach is demonstrated on three candidate designs, each an abstraction of features found in real systems.

Reductions in abortion-related mortality following policy reform: evidence from Romania, South Africa and Bangladesh

PubMed Central

2011-01-01

Unsafe abortion is a significant contributor to worldwide maternal mortality; however, abortion law and policy liberalization could lead to drops in unsafe abortion and related deaths. This review provides an analysis of changes in abortion mortality in three countries where significant policy reform and related service delivery occurred. Drawing on peer-reviewed literature, population data and grey literature on programs and policies, this paper demonstrates the policy and program changes that led to declines in abortion-related mortality in Romania, South Africa and Bangladesh. In all three countries, abortion policy liberalization was followed by implementation of safe abortion services and other reproductive health interventions. South Africa and Bangladesh trained mid-level providers to offer safe abortion and menstrual regulation services, respectively, Romania improved contraceptive policies and services, and Bangladesh made advances in emergency obstetric care and family planning. The findings point to the importance of multi-faceted and complementary reproductive health reforms in successful implementation of abortion policy reform. PMID:22192901

Objective Since research that enrolls noncompetent patients with Alzheimers disease and does not present potential benefit to subjects is the source of substantial ethical controversy, we assessed willingness to have a proxy for research decision making, and, for each of two Alzheimers disease biomarker studies (minimal risk blood draw and a greater than minimal risk blood draw and lumbar puncture), willingness to grant an advance consent, and willingness to grant a proxy leeway over advance consent. Methods Face to face survey of 538 persons 65 and over who resided in the Southeastern Pennsylvania region Results The majority 83% (445/538) granted advance consent to a blood draw study and nearly half to a blood draw plus lumbar puncture 259 (48%). Most persons (96%) were willing to identify a proxy for research decision making and most were willing to grant their proxy leeway over their advance consent: blood draw 434 (81%), and 375 (70%) blood draw plus lumbar puncture. Combining the preferences for advance consent and leeway, the proportion who would permit being enrolled in the blood draw and spinal fluid sample studies were, respectively, 92% (497/538) and 75% (404/538). Multi-variate models showed that willingness to be enrolled in research was most strongly associated with a favorable attitude about biomedical research. Conclusions Older adults generally support enrolling noncompetent persons with Alzheimers disease into research that does not present a benefit to subjects. Willingness to grant their proxy leeway over advance consent and a favorable attitude about biomedical research substantially explain this willingness. PMID:18923066

In the present work, uniaxial tensile tests were carried out to evaluate the stress-strain response of AA2014, AA5052 and AA6082 aluminum alloys at four temperatures: 303, 423, 523 and 623 K, and three strain rates: 0.0022, 0.022 and 0.22 s-1. It was found that the Cowper-Symonds model was not a robust constitutive model, and it failed to predict the flow behavior, particularly the thermal softening at higher temperatures. Subsequently, a comparative study was made on the capability of Johnson-Cook (JC), modified Zerilli-Armstrong (m-ZA), modified Arrhenius (m-ARR) and artificial neural network (ANN) for modeling the constitutive behavior of all the three aluminum alloys under the mentioned strain rates and temperatures. Also, the improvement in formability of the materials was evaluated at an elevated temperature of 623 K in terms of cup height and maximum safe strains by conducting cylindrical cup deep drawing experiments under two different punch speeds of 4 and 400 mm/min. The cup heights increased during warm deep drawing due to thermal softening and increase in failure strains. Also, a small reduction in cup height was observed when the punch speed increased from 4 to 400 mm/min at 623 K. Hence, it was suggested to use high-speed deformation at elevated temperature to reduce both punch load and cycle time during the deep drawing process.

Objectives In Zambia, despite a relatively liberal legal framework, there remains a substantial burden of unsafe abortion. Many women do not use skilled providers in a well-equipped setting, even where these are available. The aim of this study was to describe women's knowledge of the law relating to abortion and attitudes towards abortion in Zambia. Setting Community-based survey in Central, Copperbelt and Lusaka provinces. Participants 1484 women of reproductive age (15–44 years). Primary and secondary outcome measures Correct knowledge of the legal grounds for abortion, attitudes towards abortion services and the previous abortions of friends, family or other confidants. Descriptive statistics and multivariable logistic regression were used to analyse how knowledge and attitudes varied according to sociodemographic characteristics. Results Overall, just 16% (95% CI 11% to 21%) of women of reproductive age correctly identified the grounds for which abortion is legal. Only 40% (95% CI 32% to 45% of women of reproductive age knew that abortion was legally permitted in the extreme situation where the pregnancy threatens the life of the mother. Even in urban areas of Lusaka province, only 55% (95% CI 41% to 67%) of women knew that an abortion could legally take place to save the mother's life. Attitudes remain conservative. Women with correct knowledge of abortion law in Zambia tended to have more liberal attitudes towards abortion and access to safe abortion services. Neither correct knowledge of the law nor attitudes towards abortion were associated with knowing someone who previously had an induced abortion. Conclusions Poor knowledge and conservative attitudes are important obstacles to accessing safe abortion services. Changing knowledge and attitudes can be challenging for policymakers and public health practitioners alike. Zambia could draw on its previous experience in dealing with its large HIV epidemic to learn cross-cutting lessons in effective mass communication on what is a difficult and sensitive issue.

Absconding from acute psychiatric inpatient units is a significant issue with serious social, economic, and emotional costs. A qualitative study was undertaken to explore the experiences of people (n = 12) who had been held involuntarily under the local mental health act in an Australian inpatient psychiatric unit, and who had absconded (or attempted to abscond) during this time. The aim of the study was to explore why people abscond from psychiatric inpatient units, drawing on published work from health geography on the significance of the person-place encounter, and in particular the concept of 'therapeutic landscapes'. The findings show that the inpatient unit is perceived as a safe or unsafe place, dependent on the dialectical relationship between the physical, individual, social, and symbolic aspects of the unit. Consumers absconded when the unit was perceived as unsafe. Forming a therapeutic relationship with staff, familiarity with the unit, a comfortable environment, and positive experiences with other consumers all supported perceptions that the unit was safe, decreasing the likelihood of absconding. Findings extend existing work on the person-place encounter within psychiatric inpatient units, and bring new knowledge about the reasons why consumers abscond. Implications for practice are discussed. © 2012 The Authors; International Journal of Mental Health Nursing © 2012 Australian College of Mental Health Nurses Inc.

[Purpose] This study is designed to compare the effects of abdominal drawing-in exercise and myofascial release on pain, flexibility, and balance of elderly females. [Subjects and Methods] Forty elderly females aged 65 or older who had complained of low back pain for three months or longer were selected as the subjects. They were randomly and equally assigned to either an abdominal drawing-in group or a myofascial release group. The subjects conducted exercise three times per week, 40 minutes each time, for eight weeks. As evaluation tools, visual analogue scale for pain, remodified schober test for flexibility, and upright posture with eye opening on hard platform, upright posture with eye closing on hard platform, upright posture with eye opening on soft platform, upright posture with eye closing on soft platform using tetrax for balance were used. [Results] The abdominal drawing-in exercise group saw significant difference in pain and balance after the exercise compared to before the exercise. The myofascial release group saw significant difference in pain and flexibility after exercise compared to before the exercise. [Conclusion] The above study showed that abdominal drawing-in exercise affected elderly females regarding pain and balance and myofascial release influenced their pain and flexibility.

Background/Aims Constructional apraxia (CA) is usually diagnosed by having patients draw figures; however, the reported assessments only evaluate the drawn figure. We designed a new assessment battery for CA (the Mie Constructional Apraxia Scale, MCAS) which includes both the shape and drawing process, and investigated its utility against other assessment methods. Methods We designed the MCAS, and evaluated inter- and intrarater reliability. We also investigated the sensitivity, specificity, and positive and negative predictive values in dementia patients, and compared MCAS assessment with other reported batteries in the same subjects. Results Moderate interrater reliability was shown for speech therapists with limited experience. Moderate to substantial intrarater reliability was shown several weeks after initial assessment. When cutoff scores and times were set at 2/3 points and 39/40 s, sensitivity and specificity were 77.1 and 70.4%, respectively, with positive and negative predictive values of 80.0 and 66.7%, respectively. Dementia patients had significantly worse scores and times for Necker cube drawing than an elderly control group on the MCAS, and on other assessments. Conclusions We conclude that the MCAS, which includes both the assessment of the drawn Necker cube shape and the drawing process, is useful for detecting even mild CA. PMID:27790241

Leonardo da Vinci and Andreas Vesalius; the shoulder girdle and the spine, a comparison.

PubMed

Ganseman, Y; Broos, P

2008-01-01

Leonardo Da Vinci and Andreas Vesalius were two important renaissance persons; Vesalius was a surgeon-anatomist who delivered innovative work on the study of the human body, Leonardo da Vinci was an artist who delivered strikingly accurate and beautiful drawings on the human body. Below we compare both masters with regard to their knowledge of the working of the muscles, their method and system of dissection and their system and presentation of the drawings. The investigation consisted of a comparison between both anatomists, in particular concerning their study on the shoulder girdle and spine, by reviewing their original work as well as already existing literature on this subject. The investigation led to the conclusion that the drawings mentioned meant a change in history, and were of high quality, centuries ahead of their time. Both were anatomists, both were revolutionary, only one changed history at the moment itself, while the other changed history centuries later. Leonardo has made beautiful drawings that are at a match with the drawings of today or are even better. Vesalius set the start for medicine as a science as it is until this day. Their lives differed as strongly as their impact. In the light of their time, the achievement they made was extraordinary.

Skepticism and Denial: Drawing a line

NASA Astrophysics Data System (ADS)

Byrne, J. M.; Brown, M. B.; Peacock, K.

2016-12-01

Climate denialism is distinct from a merely skeptical attitude towards generally accepted views in climate science. But drawing the line between them takes care—there are similarities between skepticism and denial, including a shared reluctance to accept conclusions that nearly all qualified scientists take to be well-justified. Here we will explore both how to draw the line, and how to effectively communicate the differences between denial and skepticism. Identifying which of these two terms best describes someone's attitude turns on whether they reject a generally accepted view based on a `high threshold' for acceptance of conclusions in general, or from a preference that the conclusion in question be false. In most cases, denialism manifests in disregard and mistreatment of evidence, including selective quotation, credulous endorsement of bad sources and incredulous rejection of good sources. Historically, current accepted views became dominant as alternatives were excluded and arguments supporting current views accumulated. The accumulated record of evidence and successful application of those views sets a high bar for proposed alternatives to them. Pure skeptics may refuse to endorse generally accepted views without rejecting or distorting the strong evidence for those views, and typically support policy responses based on the implications of that evidence. But deniers who reject scientific conclusions reject the evidence for those views while endorsing views that a true skeptic would regard as less plausible and well-supported than the accepted views. Thus motivated cognition is the key to defining denial. Pascal's famous argument for belief in God illustrates the problem: even assuming God's existence to be extremely improbable, the expected value of believing is far higher than the expected value of disbelieving. But Pascal's argument undermines its own methodology: without reasons to rely on beliefs as reliable guides to successful action, cost-benefit calculations cannot be justified at all. The contribution of this work to the proposed course will aim to ensure students learn how the basic principles needed to understand anthropogenic warming emerged, and why those principles are solidly grounded.

An investigation of school violence through Turkish children's drawings.

PubMed

Yurtal, Filiz; Artut, Kazim

2010-01-01

This study investigates Turkish children's perception of violence in school as represented through drawings and narratives. In all, 66 students (12 to 13 years old) from the middle socioeconomic class participated. To elicit children's perception of violence, they were asked to draw a picture of a violent incident they had heard, experienced, or witnessed. Children mostly drew pictures of violent events among children (33 pictures). Also, there were pictures of violent incidents perpetrated by teachers and directors against children. It was observed that violence influenced children. Violence was mostly depicted in school gardens (38 pictures), but there were violent incidents everywhere, such as in classrooms, corridors, and school stores as well. Moreover, it was found that brute force was the most referred way of violence in the children's depictions (38 pictures). In conclusion, children clearly indicated that there was violence in schools and they were affected by it.

Telemonitoring is an already realized implementation of digital transformation in the healthcare system. It has the potential to support and secure a sustainable and comprehensive provision of healthcare for a rising number of chronically ill patients, e. g. patients with chronic heart failure. Remote regions in particular can profit from the benefits of telemonitoring; however, so far telemonitoring services have not become truly established in the German healthcare market. Together with experts from politics, science and practice, a scenario analysis "Health Care System 2025 - A Place for Telemonitoring?" was carried out with the aim to examine the future development of the healthcare market and to draw conclusions for providers of telemonitoring services or devices. The scenario analysis contained two workshops and an expert survey and was supported by a scenario software. The current drivers and barriers of the diffusion of telemonitoring were identified and the most relevant factors that influence the future development of the healthcare market were discussed. Based on those influencing factors, three different scenarios were determined: (1) administrating rather than shaping, (2) safely into the future and (3) interconnected and digital world. In the subsequent consequence analysis activities were defined, which describe the necessary infrastructure, software instruments, organizational structures and provision of services and discuss possible activities, which prepare telemonitoring solutions for the future.

Currently, there are limited and scarce models to teach complex liver resections by laparoscopy. The aim of this study is to present a hand-assisted technique to teach complex laparoscopic hepatectomies for fellows in liver surgery. Laparoscopic hand-assisted approach for resections of liver lesions located in posterosuperior segments (7, 6/7, 7/8, 8) was performed by the trainees with guidance and intermittent intervention of a senior surgeon. Data as: (1) percentage of time that the senior surgeon takes the surgery as main surgeon, (2) need for the senior surgeon to finish the procedure, (3) necessity of conversion, (4) bleeding with hemodynamic instability, (5) need for transfusion, (6) oncological surgical margins, were evaluated. In total, 12 cases of complex laparoscopic liver resections were performed by the trainee. All cases included deep lesions situated on liver segments 7 or 8. The senior surgeon intervention occurred in a mean of 20% of the total surgical time (range, 0% to 50%). A senior intervention >20% was necessary in 2 cases. There was no need for conversion or reoperation. Neither major bleeding nor complications resulted from the teaching program. All surgical margins were clear. This preliminary report shows that hand-assistance is a safe way to teach complex liver resections without compromising patient safety or oncological results. More cases are still necessary to draw definitive conclusions about this teaching method.

Objective: Suicide remains a major global public health issue for young people. The reach and accessibility of online and social media-based interventions herald a unique opportunity for suicide prevention. To date, the large body of research into suicide prevention has been undertaken atheoretically. This paper provides a rationale and theoretical framework (based on the interpersonal theory of suicide), and draws on our experiences of developing and testing online and social media-based interventions. Method: The implementation of three distinct online and social media-based intervention studies, undertaken with young people at risk of suicide, are discussed. We highlight the ways that these interventions can serve to bolster social connectedness in young people, and outline key aspects of intervention implementation and moderation. Results: Insights regarding the implementation of these studies include careful protocol development mindful of risk and ethical issues, establishment of suitably qualified teams to oversee development and delivery of the intervention, and utilisation of key aspects of human support (i.e., moderation) to encourage longer-term intervention engagement. Conclusions: Online and social media-based interventions provide an opportunity to enhance feelings of connectedness in young people, a key component of the interpersonal theory of suicide. Our experience has shown that such interventions can be feasibly and safely conducted with young people at risk of suicide. Further studies, with controlled designs, are required to demonstrate intervention efficacy. PMID:27274743

Background Advances in mobile telecommunication, improved mobile internet and affordability have led to a significant increase in smartphone use within medicine. The capability of instant messaging, photography, videography, word processing, drawing and internet access allow significant potential in this small portable device. Smartphone use within medicine has grown tremendously worldwide given its affordability, improved internet and capabilities. Methods We have searched for apps specifically helpful in the perioperative care of microsurgical breast reconstructive patients. Results The useful apps have been subdivided: (I) communication apps—multimedia messaging, WhatsApp, PicSafeMedi: allow efficient communication via text, picture and video messages leading to earlier assessment and definitive management of free flaps; (II) storage apps—Notability, Elogbook: electronic storage of patient notes and logbooks of case which can be shared with others if required; (III) educational apps—FlapApp, Touch Surgery, PubMed on tap: step by step guides to surgical procedures to aid learning and medical journal database; (IV) flap monitoring app—SilpaRamanitor: free flap monitoring app based on photographic analysis for earlier detection of compromised flaps. Conclusions There has been remarkable growth in smartphones use among surgeons. Apps are being developed for every conceivable use. The future will be in wearable smart devices that allow continuous monitoring with the potential to instigate change should deviations from the norm occur. The smart watch is the start of this digital revolution. PMID:27047783

Does robotics improve minimally invasive rectal surgery? Functional and oncological implications.

2016-02-01

Robot-assisted surgery has been reported to be a safe and effective alternative to conventional laparoscopy for the treatment of rectal cancer in a minimally invasive manner. Nevertheless, substantial data concerning functional outcomes and long-term oncological adequacy is still lacking. We aimed to assess the current role of robotics in rectal surgery focusing on patients' functional and oncological outcomes. A comprehensive review was conducted to search articles published in English up to 11 September 2015 concerning functional and/or oncological outcomes of patients who received robot-assisted rectal surgery. All relevant papers were evaluated on functional implications such as postoperative sexual and urinary dysfunction and oncological outcomes. Robotics showed a general trend towards lower rates of sexual and urinary postoperative dysfunction and earlier recovery compared with laparoscopy. The rates of 3-year local recurrence, disease-free survival and overall survival of robotic-assisted rectal surgery compared favourably with those of laparoscopy. This study fails to provide solid evidence to draw definitive conclusions on whether robotic systems could be useful in ameliorating the outcomes of minimally invasive surgery for rectal cancer. However, the available data suggest potential advantages over conventional laparoscopy with reference to functional outcomes. © 2016 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

Copper concentration was estimated in tap water samples obtained from 70 households in Zagreb, serviced by a public water supply system. First-draw and flushed samples of tap water were collected in the morning and total copper concentration was determined by graphite furnace atomic absorption spectrometry with Zeeman-effect background correction. We also estimated the contribution of plumbing material to copper concentrations in tap water. In households with copper pipes, median and range copper values were 310 μg L-1 [(27 to 632) μg L-1] in first-draw samples and 16 μg L-1 [(5 to 52) μg L-1] in flushed samples. Corresponding values for households with galvanised pipes were 140 μg L-1 [(11 to 289) μg L-1] and 8 μg L-1 [(1 to 42) μg L-1], respectively. Copper concentrations in household tap water in Zagreb were far below the proposed safe limits set by the Croatian and WHO regulations and EPA standards, and drinking water in Zagreb is not a significant source of copper exposure.

To describe a technique for extemporaneously drawing up bevacizumab for intravitreal injection (IVT) and report the rate of post-injection endophthtalmitis. Retrospective monocentric analysis (January 2010-December 2014) of all IVT of bevacizumab drawn up with the following technique: in the operating room (class ISO 7) through a mini-spike with an integrated bacteria retentive air filter. The surgeon was wearing sterile gloves and a mask. The assisting nurse wore a mask. The bevacizumab vial was discarded at the end of each session. Six thousand two hundred and thirty-six bevacizumab injections were performed. One case of endophthalmitis was noted (0.016%). During the same period, 4 cases of endophthalmitis were found after IVT of other drugs (4/32,992; 0.012%. P=0.8). Intravitreal injection of bevacizumab after extemporaneous withdrawal through a mini-spike filter is a simple and safe technique. The risk of postoperative endophthalmitis is very low. This simple technique facilitates access to compounded bevacizumab. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

Can We Draw General Conclusions from Interval Training Studies?

Interval training (IT) has been used for many decades with the purpose of increasing performance and promoting health benefits while demanding a relatively small amount of time. IT can be defined as intermittent periods of intense exercise separated by periods of recovery and has been divided into high-intensity interval training (HIIT), sprint interval training (SIT), and repeated sprint training (RST). IT use has resulted in the publication of many studies and many of them with conflicting results and positions. The aim of this article was to move forward and understand the studies' protocols in order to draw accurate conclusions, as well as to avoid previous mistakes and effectively reproduce previous protocols. When analyzing the literature, we found many inconsistencies, such as the controversial concept of 'supramaximal' effort, a misunderstanding with regard to the term 'high intensity,' and the use of different strategies to control intensity. The adequate definition and interpretation of training intensity seems to be vital, since the results of IT are largely dependent on it. These observations are only a few examples of the complexity involved in IT prescription, and are discussed to illustrate some problems with the current literature regarding IT. Therefore, it is our opinion that it is not possible to draw general conclusions about IT without considering all variables used in IT prescription, such as exercise modality, intensity, effort and rest times, and participants' characteristics. In order to help guide researchers and health professionals in their practices it is important that experimental studies report their methods in as much detail as possible and future reviews and meta-analyses should critically discuss the articles included in the light of their methods to avoid inappropriate generalizations.

What Do Differences Between Multi-voxel and Univariate Analysis Mean? How Subject-, Voxel-, and Trial-level Variance Impact fMRI Analysis

PubMed Central

Davis, Tyler; LaRocque, Karen F.; Mumford, Jeanette; Norman, Kenneth A.; Wagner, Anthony D.; Poldrack, Russell A.

2014-01-01

Multi-voxel pattern analysis (MVPA) has led to major changes in how fMRI data are analyzed and interpreted. Many studies now report both MVPA results and results from standard univariate voxel-wise analysis, often with the goal of drawing different conclusions from each. Because MVPA results can be sensitive to latent multidimensional representations and processes whereas univariate voxel-wise analysis cannot, one conclusion that is often drawn when MVPA and univariate results differ is that the activation patterns underlying MVPA results contain a multidimensional code. In the current study, we conducted simulations to formally test this assumption. Our findings reveal that MVPA tests are sensitive to the magnitude of voxel-level variability in the effect of a condition within subjects, even when the same linear relationship is coded in all voxels. We also find that MVPA is insensitive to subject-level variability in mean activation across an ROI, which is the primary variance component of interest in many standard univariate tests. Together, these results illustrate that differences between MVPA and univariate tests do not afford conclusions about the nature or dimensionality of the neural code. Instead, targeted tests of the informational content and/or dimensionality of activation patterns are critical for drawing strong conclusions about the representational codes that are indicated by significant MVPA results.

We analyse the report evaluating drug system safety in Andalusian public hospitals published by the Spanish Ministry of Health and Consumption in 2008 and establish a grading system to assess safe medication practices in Andalusian hospitals and prioritise areas needing improvement. We developed a catalogue of best practices available in the web environment belonging to the Andalusian health care quality agency's patient safety observatory. We publicised the strategy through training seminars and implemented a system allowing hospitals to evaluate the degree of compliance for each of the best practices, and based on that system, we were able to draw up a map of centres of reference. We found areas for improvement among several of the questionnaire's fundamental criteria. These areas for improvement were related to normal medication procedures in daily clinical practice. We therefore wrote 7 best practice guides that provide a cross-section of the assessment components of the questionnaire related to the clinical process needing improvement. The self-evaluation questionnaire adapted by ISMP-Spain is a good tool for designing a systematic, rational intervention to promote safe medication practices and intended for a group of hospitals that share the same values.

Diagnosis of the OCD Patients using Drawing Features of the Bender Gestalt Shapes

PubMed Central

Boostani, R.; Asadi, F.; Mohammadi, N.

2017-01-01

Background: Since psychological tests such as questionnaire or drawing tests are almost qualitative, their results carry a degree of uncertainty and sometimes subjectivity. The deficiency of all drawing tests is that the assessment is carried out after drawing the objects and lots of information such as pen angle, speed, curvature and pressure are missed through the test. In other words, the psychologists cannot assess their patients while running the tests. One of the famous drawing tests to measure the degree of Obsession Compulsion Disorder (OCD) is the Bender Gestalt, though its reliability is not promising. Objective: The main objective of this study is to make the Bender Gestalt test quantitative; therefore, an optical pen along with a digital tablet is utilized to preserve the key drawing features of OCD patients during the test. Materials and Methods: Among a large population of patients who referred to a special clinic of OCD, 50 under therapy subjects voluntarily took part in this study. In contrast, 50 subjects with no sign of OCD performed the test as a control group. This test contains 9 shapes and the participants were not constraint to draw the shapes in a certain interval of time; consequently, to classify the stream of feature vectors (samples through drawing) Hidden Markov Model (HMM) is employed and its flexibility increased by incorporating the fuzzy technique into its learning scheme. Results: Applying fuzzy HMM classifier to the data stream of subjects could classify two groups up to 95.2% accuracy, whereas the results by applying the standard HMM resulted in 94.5%. In addition, multi-layer perceptron (MLP), as a strong static classifier, is applied to the features and resulted in 86.6% accuracy. Conclusion: Applying the pair of T-test to the results implies a significant supremacy of the fuzzy HMM to the standard HMM and MLP classifiers. PMID:28462208

Safer Liquid Natural Gas

NASA Technical Reports Server (NTRS)

1976-01-01

After the disaster of Staten Island in 1973 where 40 people were killed repairing a liquid natural gas storage tank, the New York Fire Commissioner requested NASA's help in drawing up a comprehensive plan to cover the design, construction, and operation of liquid natural gas facilities. Two programs are underway. The first transfers comprehensive risk management techniques and procedures which take the form of an instruction document that includes determining liquid-gas risks through engineering analysis and tests, controlling these risks by setting up redundant fail safe techniques, and establishing criteria calling for decisions that eliminate or accept certain risks. The second program prepares a liquid gas safety manual (the first of its kind).

Treating ADHD With Suggestion: Neurofeedback and Placebo Therapeutics.

PubMed

Thibault, Robert T; Veissière, Samuel; Olson, Jay A; Raz, Amir

2018-06-01

We propose that clinicians can use suggestion to help treat conditions such as ADHD. We use EEG neurofeedback as a case study, alongside evidence from a recent pilot experiment utilizing a sham MRI scanner to highlight the therapeutic potential of suggestion-based treatments. The medical literature demonstrates that many practitioners already prescribe treatments that hardly outperform placebo comparators. Moreover, the sham MRI experiment showed that, even with full disclosure of the procedure, suggestion alone can reduce the symptomatology of ADHD. Non-deceptive suggestion-based treatments, especially those drawing on accessories from neuroscience, may offer a safe complement and potential alternative to current standard of care for individuals with ADHD.

Memorisation methods in science education: tactics to improve the teaching and learning practice

NASA Astrophysics Data System (ADS)

Pals, Frits F. B.; Tolboom, Jos L. J.; Suhre, Cor J. M.; van Geert, Paul L. C.

2018-01-01

How can science teachers support students in developing an appropriate declarative knowledge base for solving problems? This article focuses on the question whether the development of students' memory of scientific propositions is better served by writing propositions down on paper or by making drawings of propositions either by silent or muttering rehearsal. By means of a memorisation experiment with eighth- and ninth-grade students, we answer this question. In this experiment, students received instruction to memorise nine science propositions and to reproduce them afterwards. To support memorisation students were randomly assigned either to a group that received instruction to write each proposition on paper or to a group that received instruction to make a drawing about the content of the proposition. In addition, half of the students in both groups received instruction to mutter and the other half of them received instruction to write or draw in silence. The main conclusion from the experiment is that after four weeks students who had made a drawing remembered significantly more propositions than those who had memorised the propositions by writing them down. Our research further revealed that it did not matter whether students muttered or memorised silently.

SYBR safeTM efficiently replaces ethidium bromide in Aspergillus fumigatus gene disruption.

PubMed

Canela, H M S; Takami, L A; Ferreira, M E S

2017-02-08

Invasive aspergillosis is a disease responsible for high mortality rates, caused mainly by Aspergillus fumigatus. The available drugs are limited and this disease continues to occur at an unacceptable frequency. Gene disruption is essential in the search for new drug targets. An efficient protocol for A. fumigatus gene disruption was described but it requires ethidium bromide, a genotoxic agent, for DNA staining. Therefore, the present study tested SYBR safe TM , a non-genotoxic DNA stain, in A. fumigatus gene disruption protocol. The chosen gene was cipC, which has already been disrupted successfully in our laboratory. A deletion cassette was constructed in Saccharomyces cerevisiae and used in A. fumigatus transformation. There was no statistical difference between the tested DNA stains. The success rate of S. cerevisiae transformation was 63.3% for ethidium bromide and 70% for SYBR safe TM . For A. fumigatus gene disruption, the success rate for ethidium bromide was 100 and 97% for SYBR safe TM . In conclusion, SYBR safe TM efficiently replaced ethidium bromide, making this dye a safe and efficient alternative for DNA staining in A. fumigatus gene disruption.

Safe Practices for Copy and Paste in the EHR. Systematic Review, Recommendations, and Novel Model for Health IT Collaboration.

Copy and paste functionality can support efficiency during clinical documentation, but may promote inaccurate documentation with risks for patient safety. The Partnership for Health IT Patient Safety was formed to gather data, conduct analysis, educate, and disseminate safe practices for safer care using health information technology (IT). To characterize copy and paste events in clinical care, identify safety risks, describe existing evidence, and develop implementable practice recommendations for safe reuse of information via copy and paste. The Partnership 1) reviewed 12 reported safety events, 2) solicited expert input, and 3) performed a systematic literature review (2010 to January 2015) to identify publications addressing frequency, perceptions/attitudes, patient safety risks, existing guidance, and potential interventions and mitigation practices. The literature review identified 51 publications that were included. Overall, 66% to 90% of clinicians routinely use copy and paste. One study of diagnostic errors found that copy and paste led to 2.6% of errors in which a missed diagnosis required patients to seek additional unplanned care. Copy and paste can promote note bloat, internal inconsistencies, error propagation, and documentation in the wrong patient chart. Existing guidance identified specific responsibilities for authors, organizations, and electronic health record (EHR) developers. Analysis of 12 reported copy and paste safety events was congruent with problems identified from the literature review. Despite regular copy and paste use, evidence regarding direct risk to patient safety remains sparse, with significant study limitations. Drawing on existing evidence, the Partnership developed four safe practice recommendations: 1) Provide a mechanism to make copy and paste material easily identifiable; 2) Ensure the provenance of copy and paste material is readily available; 3) Ensure adequate staff training and education; 4) Ensure copy and paste practices are regularly monitored, measured, and assessed.

An evaluation of learning clinical decision-making for early rehabilitation in the ICU via interactive education with audience response system.

Knowledge-related barriers to safely implement early rehabilitation programs in intensive care units (ICUs) may be overcome via targeted education. The purpose of this study was to evaluate the effectiveness of an interactive educational session on short-term knowledge of clinical decision-making for safe rehabilitation of patients in ICUs. A case-based teaching approach, drawing from published safety recommendations for initiation of rehabilitation in ICUs, was used with a multidisciplinary audience. An audience response system was incorporated to promote interaction and evaluate knowledge before vs. after the educational session. Up to 175 audience members, of 271 in attendance (129 (48%) physical therapists, 51 (19%) occupational therapists, 31 (11%) nursing, 14 (5%) physician, 46 (17%) other), completed both the pre- and post-test questions for each of the six unique patient cases. In four of six patient cases, there was a significant (p< 0.001) increase in identifying the correct answer regarding initiation of rehabilitation activities. This learning effect was similar irrespective of participants' years of experience and clinical discipline. An interactive, case-based, educational session may be effective for increasing short-term knowledge, and identifying knowledge gaps, regarding clinical decision-making for safe rehabilitation of patients in ICUs. Implications for Rehabilitation Lack of knowledge regarding the safety considerations for early rehabilitation of ICU patients is a barrier to implementing early rehabilitation. Interactive educational formats, such as the use of audience response systems, offer a new method of teaching and instantly assessing learning of clinically important information. In a small study, we have shown that an interactive, case-based educational format may be used to effectively teach clinical decision-making for the safe rehabilitation of ICU patients to a diverse audience of clinicians.

Assuring the safety of genetically modified (GM) foods: the importance of an holistic, integrative approach.

PubMed

Cockburn, Andrew

2002-09-11

Genes change continuously by natural mutation and recombination enabling man to select and breed crops having the most desirable traits such as yield or flavour. Genetic modification (GM) is a recent development which allows specific genes to be identified, isolated, copied and inserted into other plants with a high level of specificity. The food safety considerations for GM crops are basically the same as those arising from conventionally bred crops, very few of which have been subject to any testing yet are generally regarded as being safe to eat. In contrast a rigorous safety testing paradigm has been developed for GM crops, which utilises a systematic, stepwise and holistic approach. The resultant science based process, focuses on a classical evaluation of the toxic potential of the introduced novel trait and the wholesomeness of the transformed crop. In addition, detailed consideration is given to the history and safe use of the parent crop as well as that of the gene donor. The overall safety evaluation is conducted under the concept known as substantial equivalence which is enshrined in all international crop biotechnology guidelines. This provides the framework for a comparative approach to identify the similarities and differences between the GM product and its comparator which has a known history of safe use. By building a detailed profile on each step in the transformation process, from parent to new crop, and by thoroughly evaluating the significance from a safety perspective, of any differences that may be detected, a very comprehensive matrix of information is constructed which enables the conclusion as to whether the GM crop, derived food or feed is as safe as its traditional counterpart. Using this approach in the evaluation of more than 50 GM crops which have been approved worldwide, the conclusion has been that foods and feeds derived from genetically modified crops are as safe and nutritious as those derived from traditional crops. The lack of any adverse effects resulting from the production and consumption of GM crops grown on more than 300 million cumulative acres over the last 5 years supports these safety conclusions.

There is increasing evidence that the cerebellum has a role in the pathophysiology of primary focal hand dystonia and might provide an intervention target for non-invasive brain stimulation to improve function of the affected hand. The primary objective of this study was to determine if cerebellar transcranial direct current stimulation (tDCS) improves handwriting and cyclic drawing kinematics in people with hand dystonia, by reducing cerebellar-brain inhibition (CBI) evoked by transcranial magnetic stimulation (TMS). Eight people with dystonia (5 writer's dystonia, 3 musician's dystonia) and eight age-matched controls completed the study and underwent cerebellar anodal, cathodal and sham tDCS in separate sessions. Dystonia severity was assessed using the Writer's Cramp Rating Scale (WRCS) and the Arm Dystonia Disability Scale (ADDS). The kinematic measures that differentiated the groups were; mean stroke frequency during handwriting and fast cyclic drawing and average pen pressure during light cyclic drawing. TMS measures of cortical excitability were no different between people with FHD and controls. There was a moderate, negative relationship between TMS-evoked CBI at baseline and the WRCS in dystonia. Anodal cerebellar tDCS reduced handwriting mean stroke frequency and average pen pressure, and increased speed and reduced pen pressure during fast cyclic drawing. Kinematic measures were not associated with a decrease in CBI within an individual. In conclusion, cerebellar anodal tDCS appeared to improve kinematics of handwriting and circle drawing tasks; but the underlying neurophysiological mechanism remains uncertain. A study in a larger homogeneous population is needed to further investigate the possible therapeutic benefit of cerebellar tDCS in dystonia.

2017-07-01

This article describes the development and evaluation of C-SAFE (Sexual Awareness for Everyone), a computer-delivered sexual health promotion program for Latinas. We first describe the process of adapting an evidence-based, group-level intervention into an individually administered computer-delivered program. We then present the methods and results of a randomized control trial with 321 Latinas in California and Florida to test C-SAFE's preliminary efficacy in reducing sexual health risk. We found no statistically significant differences between the two conditions at a six-month follow-up in terms of sexual behaviors or attitudes toward sexually transmitted infections and condoms, although C-SAFE women reported fewer days in the past month when their mental health was not good (p = .02). C-SAFE condition women also reported more satisfaction than control condition women in their assessment of information presentation (on a scale of 1 = poor and 5 = excellent; C-SAFE = 4.45 vs. control = 4.25, p = .053) and having learned something new (C-SAFE = 95.1% vs. control = 79.3%, χ 2 < 0.001), with utility of content for Latinas approaching significance (C-SAFE = 4.50 vs. control = 4.31, p = .058). In conclusion we discuss the importance of teachable moments, matching of delivery modalities to implementation contexts, and possible directions for evidence-based sexual health promotion programs given the current sexual health landscape.

Kinematic and Pressure Features of Handwriting and Drawing: Preliminary Results Between Patients with Mild Cognitive Impairment, Alzheimer Disease and Healthy Controls

Background: Alzheimer’s disease (AD) is the most common neurodegenerative dementia of old age, and the leading chronic disease contributor to disability and dependence among older people worldwide. Clinically, AD is characterized by a progressive cognitive decline that interferes with the abil-ity to perform the activities of daily living. Handwriting and drawing are complex human activities that entail an intricate blend of cognitive, kinesthetic, and perceptual-motor features. Objective: To compare the kinematic characteristics of handwriting and drawing between patients with AD, patients with mild cognitive impairment (MCI) and healthy controls. Methods: We used a cross-sectional and observational design to assess the kinematic and pressure fea-tures of handwriting and drawing using a computerized system. Participants were asked to copy one sen-tence, write a dictated sentence and an own sentence, copy two and-three dimensions drawings, and to execute the clock drawing test. By means of discriminant analyses, we explored the value of several kin-ematic features in order to classify participants depending on their degree of cognitive functioning. Results: The sample consisted of 52 participants (23 AD, 12 MCI, and 17 healthy controls) with a mean age of 69.7 years (SD=8.11). The degree of correct classification was largely dependent on the nature of the groups to be classified and the specific task, and ranged between 63.5% and 100%. Diagnostic accu-racy based on kinematic measures showed higher specificity values for distinguishing between normal and impaired cognition (MCI and AD), and higher sensitivity was obtained when distinguishing between impaired cognition levels (MCI vs. AD). Conclusion: The kinematic features of writing and drawing procedures, rather than the final product, may be a useful and objective complement to the clinical assessment of patients with cognitive impairment.

A key indicator of a supportive campus climate for lesbian, gay, bisexual, and transgender (LGBT) college students is the existence of an LGBT student organization. This article integrates the research on high school LGBT policies and programs with social movement studies of campus activism to examine the characteristics associated with the existence of university-approved LGBT groups on North Carolina campuses. Drawing on data from the National Center for Education Statistics, campus Web sites, and other sources, logistic regression is used to examine the importance of public opinion, campus and community resources, and the institutional context in predicting the location of these student groups.

Mobility and Aging: New Directions for Public Health Action

Optimal mobility, defined as relative ease and freedom of movement in all of its forms, is central to healthy aging. Mobility is a significant consideration for research, practice, and policy in aging and public health. We examined the public health burdens of mobility disability, with a particular focus on leading public health interventions to enhance walking and driving, and the challenges and opportunities for public health action. We propose an integrated mobility agenda, which draws on the lived experience of older adults. New strategies for research, practice, and policy are needed to move beyond categorical promotion programs in walking and driving to establish a comprehensive program to enhance safe mobility in all its forms.

Nearly 3% of the population has hyperhidrosis. Quality of life is affected, impacting on social relationships and professional activity, and social anxiety disorder can sometime develop. We review the definition and causes of hyperhidrosis and the clinical evaluation of patients. After describing the different clinical aspects of the condition, we discuss the medical and surgical treatments. Of such treatments currently available, particular mention is made of the use of botulinum toxin in some forms of hyperhidrosis as an intermediate option between the traditional treatments and surgery. We also draw attention to the use of minimal access surgical techniques (videothoracoscopy), which, over the past decade, have become established as an effective, safe, and permanent approach for the treatment of hyperhidrosis when indicated.

Transanal endoscopic microsurgery is considered a safe, appropriate, and minimally invasive approach, and complications after endoscopic microsurgery are rare. We report a case of sepsis and pneumoretroperitoneum after resection of a rectal lateral spreading tumor. The patient presented with rectal mucous discharge. Colonoscopy revealed a rectal lateral spreading tumor. The patient underwent an endoscopic transanal resection of the lesion. He presented with sepsis of the abdominal focus, and imaging tests revealed pneumoretroperitoneum. A new surgical intervention was performed with a loop colostomy. Despite the existence of other reports on pneumoretroperitoneum after transanal endoscopic microsurgery, what draws attention to this case is the association with sepsis. PMID:28761873

That is Cool: the Nature Of Aesthetics in Fluid Physics

NASA Astrophysics Data System (ADS)

Hertzberg, Jean

2013-11-01

Aesthetics has historically been defined as the study of beauty and thus as a metric of art. More recently, psychologists are using the term to describe a spectrum of responses from ``I hate it'' to ``I love it.'' In the context of fluid physics, what is beautiful? What elicits a ``Wow! Awesome! Cool!'' response versus a snore? Can we use aesthetics to deepen or change students' or the public's perceptions of physics and/or the world around them? For example, students seem to appreciate the aesthetics of destruction: environmental fluid dynamics such as storms, tornadoes, floods and wildfires are often responsible for massive destruction, yet humans draw pleasure from watching such physics and the attendant destruction from a safe distance. Can this voyeurism be turned to our advantage in communicating science? Observations of student and Facebook Flow Visualization group choices for fluid physics that draw a positive aesthetic response are sorted into empirical categories; the aesthetics of beauty, power, destruction, and oddness. Each aesthetic will be illustrated with examples drawn from flow visualizations from both the Flow Visualization course (MCEN 4151) taught at the University of Colorado, Boulder, and sources on the web.

To analyze feasibility and outcomes of laparoscopic partial nephrectomy (LPN) for endophytic hilar tumors in low-intermediate (ASA I-II) risk patients. This is a single centre retrospective study. From May 2009 to September 2011, 208 LPNs were performed at our institution. Overall 11 (5.2%) elective LPNs were for hilar tumors not visible on kidney surface. Hilar tumor was defined as a mass located in the renal hilum and in contact with a major renal vessel on preoperative imaging. Procedures were carried out by a single experienced surgeon (G.G.) via retroperitoneal approach by clamping the only main renal artery. Mean (range) age of patients was 45.3 years (38.2-64.1), tumor size 1.6 cm (1.2-2.0), warm ischemia time 24 min (19-32), operative time 140 min (110-200) and estimated blood loss 270 ml (100-750). Two collecting system injuries were observed and repaired intraoperatively. No conversion to open surgery was required. Final pathological examination revealed 10 renal cell carcinomas and 1 oncocytoma. A negative surgical margin was obtained in 10/11 (91%) patients. Renal function and serum hemoglobin were nearly unaltered pre and post-surgery. No tumor recurrence was observed at mean (range) follow-up of 34 months (15-43). In experienced hands, LPN represents a feasible, safe and effective treatment for selected patients diagnosed with endophytic hilar masses. A larger number of patients and longer follow-up are required to draw definitive conclusions. Copyright © 2013 Elsevier Ltd. All rights reserved.

Chinese herbal medicine for cancer-related fatigue: a systematic review of randomized clinical trials.

PubMed

Su, Chun-Xiang; Wang, Li-Qiong; Grant, Suzanne J; Liu, Jian-Ping

2014-06-01

To assess the effectiveness and safety of Chinese herbal medicine for the treatment of cancer-related fatigue. We systematically searched seven electronic databases and two trial registries for randomized clinical trials of Chinese herbal medicine for cancer-related fatigue. Two authors independently extracted data and assessed the methodological quality of the included trials using the Cochrane risk of bias tool. Data were synthesized using RevMan 5.2 software. A total of 10 trials involving 751 participants with cancer-related fatigue were identified and the methodological quality of the included trials was generally poor. Chinese herbal medicine used alone or in combination with chemotherapy or supportive care showed significant relief in cancer-related fatigue compared to placebo, chemotherapy or supportive care based on single trials. Chinese herbal medicine plus chemotherapy or supportive care was superior to chemotherapy or supportive care in improving quality of life. Data from one trial demonstrated Chinese herbal medicine exerted a greater beneficial effect on relieving anxiety but no difference in alleviating depression. Seven trials reported adverse events and no severe adverse effects were found in Chinese herbal medicine groups. The findings from limited number of trials suggest that Chinese herbal medicine seems to be effective and safe in the treatment of cancer-related fatigue. However, the current evidence is insufficient to draw a confirmative conclusion due to the poor methodological quality of included trials. Thus, conducting rigorously designed trials on potential Chinese herbal medicine is warranted. Copyright © 2014 Elsevier Ltd. All rights reserved.

2015-06-01

Robot-assisted surgery for colon cancer has been reported in many studies, most of which worked on right and/or sigmoid colectomy. The aim of this study was to report our experience of robotic transverse colectomy with an intracorporeal anastomosis, provide details of the surgical technique, and present the theoretical benefits of the procedure. This is a retrospective review of prospectively collected data of robotic surgery for colorectal cancer performed by a single surgeon between May 2007 and February 2011. Out of 162 consecutive cases, we identified three robotic transverse colectomies, using a hand-sewn intracorporeal anastomosis. Two males and one female underwent transverse colectomies for malignant or premalignant disease. The mean docking time, time spent using the robot, and total operative time were 5, 268, and 307 min, respectively. There were no conversions to open or conventional laparoscopic technique. The mean length of specimen and number of lymph nodes retrieved were 14.1 cm and 6.7, respectively. One patient suffered from a wound seroma and recovered with conservative management. The mean hospital stay was 8.7 days. After a median follow-up of 72 months, there were no local or systemic recurrences. Robotic transverse colectomy seems to be a safe and feasible technique. It may minimize the necessity of mobilizing both colonic flexures, with facilitated intracorporeal hand-sewn anastomosis. However, further prospective studies with a larger number of patients are required to draw firm conclusions.

Specific sublingual immunotherapy (SLIT) has been proved to be a safe and effective approach in respiratory allergy. However, further research is required on aspects such as patient selection, use of optimal dosing, effects on asthma, long-term effects, and management of adverse reactions. In addition, the widely heterogeneous nature of studies on SLIT performed to date and the application of the criteria for subcutaneous immunotherapy make it difficult for the prescribing clinician to draw accurate and useful conclusions. Therefore, the QUASAR Group (QUality in the Administration of SLIT in Allergic Rhinitis), which comprises allergologists with broad clinical experience in SLIT, investigated the latest research findings and available data on this approach. Working parties were formed in 3 different categories: selection of candidates for SLIT, treatment efficacy, and adverse reactions. We performed a PubMed search for articles that were representative of each category and found 850. From these, we finally selected 266 articles, which were reviewed to retrieve data on SLIT. Evidence for each clinical question was graded according to the Oxford classification. The resulting text was evaluated on 3 occasions by all the members of the group until the final version was agreed upon. In this version, we review available evidence on SLIT, particularly with pollens, which is the subject of most articles. In areas where evidence is insufficient, an alternative agreed upon by the members of the QUASAR group is presented. Finally, we propose algorithms for selecting candidates for SLIT and for management of adverse events.

The research design that is used for this research is the Pre-test and Post-test Design. The data collection of scientific reasoning skills is collected by giving multiple choice questions before and after the lesson. The data analysis of scientific reasoning skills is using scientific reasoning assessment rubric. The results show an improvement of student’s scientific reasoning in every indicator; an improvement in generativity which shows 2 students achieving high scores, 3 students in elaboration reasoning, 4 students in justification, 3 students in explanation, 3 students in logic coherency, 2 students in synthesis. The research result in student’s explanation reasoning has the highest number of students with high scores, which shows 20 students with high scores in the pre-test and 23 students in post-test and synthesis reasoning shows the lowest number, which shows 1 student in the pretest and 3 students in posttest. The research result gives the conclusion that Drawing-based Modeling approach assisted with E-Beam Capture could not yet support student’s scientific reasoning skills comprehensively.

An exploratory study of the potential learning benefits for medical students in collaborative drawing: creativity, reflection and ‘critical looking’

PubMed Central

2013-01-01

Background Building on a series of higher educational arts/medicine initiatives, an interdisciplinary drawing module themed on the human body was developed for both year 3 Craft students and year 3 Medicine degree students. This became the subject of a research project exploring how the collaborative approach to drawing adopted on this module impacted on the students’ learning. In this article, emphasis is given to issues thought to have most potential relevance to medical education. Methods Using an ethnographic research design, the methods adopted were: direct observation of all aspects of the module sessions, audio and video recordings and photographs of the sessions, the incorporation of a semi-structured discussion at the end of each session, and anonymous student questionnaires. Results A number of key themes emerged. The complex, phased and multi-sensory nature of the ‘critical looking’ skills developed through the drawing exercises was seen as of potential value in medical education, being proposed as analogous to processes involved in clinical examination and diagnosis. The experience of interdisciplinary collaborative drawing was significant to the students as a creative, participatory and responsive form of learning. The emphasis on the physical experience of drawing and the thematic use of the human body as drawing subject led to reflective discussions about bodily knowledge and understanding. There were indications that students had a meta-cognitive awareness of the learning shifts that had occurred and the sessions provoked constructive self-reflective explorations of pre-professional identity. Conclusions This preliminary study suggests, through the themes identified, that there may be potential learning outcomes for medical students in this model of interdisciplinary collaborative drawing of the human body. Further research is needed to explore their applicability and value to medical education. There is a need to explore in more depth the beliefs, motivations and learning styles of medical students opting for the module, the significance and weighting of different learning and teaching elements in the module and the impact of the learning on medical students in the immediate post-module phase.

The Safe and Efficient Evaporation of a Solvent from Solution

NASA Astrophysics Data System (ADS)

Mahon, Andrew R.

1997-02-01

The process of evaporating a solvent from a solution can cause problems for many students. By using a water-vacuum aspirator, backflashes of water can flood the sample tube and be detrimental to the experiment. This type of apparatus can also cause problems by drawing the solution it is evaporating back into the vacuum hose, causing the student to lose part or all of the products of their experiment. Macroscale and Microscale Organic Experiments, 2nd edition (1), suggested two techniques to dissolve solvents from a mixture. It suggested blowing a stream of air over the solution from a Pasteur pipet, or attaching a Pasteur pipet to an aspirator and drawing air over the surface of the liquid. Again, the danger of blowing air over the solution leaves the risk of splattering the solution, and drawing air over the surface of the liquid as described further endangers the products of the experiment through the risk of sucking the products up into the pipet aspirator. In an effort to eliminate these problems, a new technique has been developed. By inverting an ordinary 200-mL vacuum flask and pulling a steady current of air from the vacuum apparatus through it, any type of small container can be placed under it, allowing the solvent to be evaporated in a steady, mistake-free manner . By evaporating the solvent from the container that the products will be submitted in, no sample is lost through the process of transferring it from a vacuum flask or beaker to the final container.

Abstract Background: To assess the efficacy and safety of tranexamic acid (TA) in reducing blood loss and lowering transfusion needs for patients undergoing caesarean section (CS) or vaginal delivery (VD). Methods: An electronic literature search of PubMed, EMBASE, OVID, Cochrane library, Scopus, Central, and Clinical trials.gov was performed to identify studies that evaluating the usage of TA in CS or VD. The methodological quality of included trials was assessed and data extraction was performed. Results: Finally, 25 articles with 4747 participants were included. Our findings indicated TA resulted in a reduced intra-, postoperative, and total blood loss by a mean volume of 141.25 mL (95% confidence interval [CI] −186.72 to −95.79, P < 0.00001), 36.42 mL (95% CI −46.50 to −26.34, P < 0.00001), and 154.25 mL (95% CI −182.04 to −126.47, P < 0.00001) in CS. TA administration in VD was associated with a reduced intra-, postoperative, and total blood loss by a mean volume of 22.88 mL (95% CI −50.54 to 4.77, P = 0.10), 41.24 mL (95% CI −55.50 to −26.98, P < 0.00001), and 84.79 mL (95% CI −109.93 to −59.65, P < 0.00001). In addition, TA could lower the occurrence rate of postpartum hemorrhage (PPH) and severe PPH, and reduce the risk of blood transfusions. No increased risk of deep vein thrombosis (DVT) after CS or VD was associated with TA usage, while the minor side effects were more common. Conclusions: Our findings indicated that intravenous TA for patients undergoing CS was effective and safe. Although prophylactic TA administration is associated with reduced PPH, current existing data are insufficient to draw definitive recommendations about its clinical significance due to the poor to moderate quality of the included literatures. Thus, high-quality randomized controlled trials with larger samples are needed to validate our findings. PMID:28072700

Background Neck pain (NP) and low back pain (LBP) are common symptoms bothering people in daily life. Traditional Chinese medicine (TCM) has been used to treat various symptoms and diseases in China and has been demonstrated to be effective. The objective of the present study was to review and analyze the existing data about pain and disability in TCM treatments for NP and LBP. Methods Studies were identified by a comprehensive search of databases, such as MEDLINE, EMBASE, and Cochrane Library, up to September 1, 2013. A meta-analysis was performed to evaluate the efficacy and safety of TCM in managing NP and LBP. Results Seventy five randomized controlled trials (n = 11077) were included. Almost all of the studies investigated individuals experiencing chronic NP (CNP) or chronic LBP (CLBP). We found moderate evidence that acupuncture was more effective than sham-acupuncture in reducing pain immediately post-treatment for CNP (visual analogue scale (VAS) 10 cm, mean difference (MD) = -0.58 (-0.94, -0.22), 95% confidence interval, p = 0.01), CLBP (standardized mean difference = -0.47 (-0.77, -0.17), p = 0.003), and acute LBP (VAS 10 cm, MD = -0.99 (-1.24, -0.73), p< 0.001). Cupping could be more effective than waitlist in VAS (100 mm) (MD = -19.10 (-27.61, -10.58), p < 0. 001) for CNP or medications (e.g. NSAID) for CLBP (MD = -5.4 (-8.9, -0.19), p = 0.003). No serious or life-threatening adverse effects were found. Conclusions Acupuncture, acupressure, and cupping could be efficacious in treating the pain and disability associated with CNP or CLBP in the immediate term. Gua sha, tai chi, qigong, and Chinese manipulation showed fair effects, but we were unable to draw any definite conclusions, and further research is still needed. The efficacy of tuina and moxibustion is unknown because no direct evidence was obtained. These TCM modalities are relatively safe. PMID:25710765

Code of practice for design and construction of under reamed pile foundations: IS 2911 (Part-III)—1980 presents one table in respect of safe load for bored cast in situ under reamed piles in sandy and clayey soils including black cotton soils, stem dia. of pile ranging from 20 to 50 cm and its effective length being 3.50 m. A comparative study, was taken up by working out safe pile capacity for one 400 dia., 3.5 m long bored cast in situ under reamed pile based on subsoil properties obtained from soil investigation work as well as subsoil properties of different magnitudes of clayey, sandy soils and comparing the same with the safe pile capacity shown in Table 1 of that IS Code. The study reveals that safe pile capacity computed from subsoil properties, barring a very few cases, considerably differs from that shown in the aforesaid code and looks forward for more research work and study to find out a conclusive explanation of this probable anomaly.

Biomechanics is a subject that draws on knowledge from many disciplines. One of its great practitioners in the last century was the Irish anatomist M.A. MacConaill. In this paper, we review some of MacConaill's fundamental contributions to biomechanics, namely: the hydrodynamic theory of synovial joint lubrication, the kinematics of joint motion and conjunct rotations; and the theory of spurt and shunt muscles. The aim is to revisit these topics in the light of current research, and to draw some conclusions about the import of his research in the context of recent developments in the field. The paper concludes with a discussion of science in Ireland, the development of the field of biomechanics since MacConaill's time, and some other matters.

A clean India is the responsibility of all Indians. One of the objectives of the Swachh Bharat Abhiyan (Clean India Initiative) is to bring about behavioural changes regarding healthy sanitation practices. While large-scale programs in India have increased latrine coverage, they have to some extent failed to bring behavioural changes ensuring optimal latrine use, including the safe disposal of child faeces, which is a significant source of exposure to faecal pathogens. Hence, this study was done to explore child faeces disposal practices in rural West Bengal and to elicit the determinants of unhygienic faeces disposal. Data collection was done using an interview method among the mothers of 502 under-5 children, following a pre-designed, semi-structured schedule during house-to-house visits in a set of villages in the Hooghly district of West Bengal. The prevalence of unsafe disposal of child faeces was 72.4%, and maternal education, per capita income, and water source were found to be significantly associated with unsafe child faeces disposal. This study draws attention to the unsafe disposal of child faeces in this area of India and raises questions about the efficiency of sanitation campaigns in rural India that focus on expanding coverage rather than emphasizing behavioural changes, which are crucial to ensure the safe disposal of child faeces. Thus, it is urgently necessary to strengthen efforts focusing on behavioural changes regarding the safe disposal of child faeces in order to minimise adverse health outcomes.

Vitamin D deficiency is a global public health concern. Studies of serum 25-hydroxyvitamin D (25(OH)D) determinants in young women are limited and few include objective covariates. Our aims were to define the prevalence of vitamin D deficiency and examine serum 25(OH)D correlates in an exploratory study of women aged 16-25 years. We studied 348 healthy females living in Victoria, Australia, recruited through Facebook. Data collected included serum 25(OH)D assayed by liquid chromatography-tandem MS, relevant serum biochemistry, soft tissue composition by dual-energy X-ray absorptiometry, skin melanin density, Fitzpatrick skin type, sun exposure using UV dosimeters and lifestyle factors. Mean serum 25(OH)D was 68 (sd 27) nmol/l and 26 % were vitamin D deficient (25(OH)D 2 h in the sun in summer daily, holidaying in the most recent summer period, serum Fe levels, height and multivitamin use were positively associated with 25(OH)D. Fat mass and a blood draw in any season except summer was inversely associated with 25(OH)D. Vitamin D deficiency is common in young women. Factors such as hormonal contraception, sun exposure and sun-related attitudes, as well as dietary supplement use are essential to consider when assessing vitamin D status. Further investigation into methods to safely optimise vitamin D status and to improve understanding of the impact of vitamin D status on long-term health outcomes is required.

Background Sleep-related death is tied with congenital anomalies as the leading cause of infant mortality in Kansas, and external risk factors are present in 83% of these deaths. Hospitals can impact caregiver intentions to follow risk-reduction strategies. This project assessed the current practices and policies of Kansas hospitals with regard to safe sleep. Methods A cross-sectional survey of existing safe sleep practices and policies in Kansas hospitals was performed. Hospitals were categorized based on reported delivery volume and data were compared across hospital sizes. Results Thirty-one of 73 (42%) contacted hospitals responded. Individual survey respondents represented various hospital departments including newborn/well-baby (68%), neonatal intensive care unit (3%) and other non-nursery departments or administration (29%). Fifty-eight percent of respondents reported staff were trained on infant safe sleep; 44% of these held trainings annually. High volume hospitals tended to have more annual training than low or mid volume birth hospitals. Thirty-nine percent reported a safe sleep policy, though most of these (67%) reported never auditing compliance. The top barrier to safe sleep education, regardless of delivery volume, was conflicting patient and family member beliefs. Conclusions Hospital promotion of infant safe sleep is being conducted in Kansas to varying degrees. High and mid volume birth hospitals may need to work more on formal auditing of safe sleep practices, while low volume hospitals may need more staff training. Low volume hospitals also may benefit from access to additional caregiver education materials. Finally, it is important to note hospitals should not be solely responsible for safe sleep education.

Objective Psychomotor slowing has been documented in depression. The digital Clock Drawing Test (dCDT) provides: i) a novel technique to assess both cognitive and motor aspects of psychomotor speed within the same task and ii) the potential to uncover subtleties of behavior not previously detected with non-digitized modes of data collection. Method Using digitized pen technology in 106 participants grouped by Age (younger/older) and Affect (euthymic/unmedicated depressed), we recorded cognitive and motor output by capturing how the clock is drawn rather than focusing on the final product. We divided time to completion (TTC) for Command and Copy conditions of the dCDT into metrics of percent of drawing (%Ink) versus non-drawing (%Think) time. We also obtained composite z-scores of cognition, including attention/ information processing (AIP), to explore associations of %Ink and %Think times to cognitive and motor performance. Results Despite equivalent TTC, %Ink and %Think Command times (Copy n.s.) were significant (AgeXAffect interaction:p=.03)—younger depressed spent a smaller proportion of time drawing relative to thinking compared to the older depressed group. Command %Think time negatively correlated with AIP in the older depressed group (r=−.46;p=.02). Copy %Think time negatively correlated with AIP in the younger depressed (r=−.47;p=.03) and older euthymic groups (r=−.51;p=.01). Conclusion The dCDT differentiated aspects of psychomotor slowing in depression regardless of age, while dCDT/cognitive associates for younger adults with depression mimicked patterns of older euthymics.

This study is aimed at definition of the safe and dangerous zone for screw placement with Stoppa approach for rapid identification during operation and a new way for the studies on the "safe zone." Pelvic CT data of 84 human subjects were recruited to reconstruct the three-dimensional (3D) models. The distances between the edges of the "safe zone," "dangerous zone," and specific anatomic landmarks such as the obturator canal and the pelvic brim were precisely measured, respectively. The results show that the absolute "dangerous zone" was from the pelvic brim to 3.07 cm below it and within 2.86 cm of the obturator canal, while the region 3.56 cm below the pelvic brim or 3.85 cm away from the obturator canal was the absolute "safe zone" for screw placement. The region between the absolute "safe zone" and the absolute "dangerous zone" was the relatively "dangerous zone." As a conclusion, application of computer-assisted 3D modeling techniques aids in the precise measurement of "safe zone" and "dangerous zone" in combination with Stoppa incision. It was not recommended to place screws on the absolute dangerous zone, while, for the relatively "dangerous zone," it depends on the individual variations in bony anatomy and the fracture type.

Unmasking the predicament of cultural voyeurism: a postcolonial analysis of international nursing placements.

PubMed

Racine, Louise; Perron, Amélie

2012-09-01

The growing interest in international nursing placements cannot be left unnoticed. After 11 years into this twenty-first century, violations of human rights and freedom of speech, environmental disasters, and armed conflicts still create dire living conditions for men and women around the world. Nurses have an ethical duty to address issues of social justice and global health as a means to fulfil nursing's social mandate. However, international placements raise some concerns. Drawing on the works of postcolonial theorists in nursing and social sciences, we examine the risk of replicating colonialist practices and discourses of health in international clinical placements. Referring to Bakhtin's notions of dialogism and unfinalizability, we envision a culturally safe nursing practice arising from dialogical encounters between the Self as an Other and with the Other as an Other. We suggest that exploring the intricacies of cultural and race relations in everyday nursing practice are the premises upon which nurses can understand the broader historic, racial, gendered, political and economic contexts of global health issues. Finally, we make suggestions for developing culturally safe learning opportunities at the international level without minimizing the impact of dialogical cultural encounters occurring at the local and community levels. © 2011 Blackwell Publishing Ltd.

Experimental pretesting of public health campaigns: a case study.

PubMed

Whittingham, Jill; Ruiter, Robert A C; Zimbile, Filippo; Kok, Gerjo

2008-01-01

The aim of the present study is to demonstrate the merits of evaluating new public health campaign materials in the developmental phase using an experimental design. This is referred to as experimental pretesting. In practice, most new materials are tested only after they have been distributed using nonexperimental or quasiexperimental designs. In cases where materials are pretested prior to distribution, pretesting is usually done using qualitative research methods such as focus groups. Although these methods are useful, they cannot reliably predict the effectiveness of new campaign materials in a developmental phase. Therefore, we suggest when pretesting new materials, not only qualitative research methods but also experimental research methods must be used. The present study discusses an experimental pretest study of new campaign materials intended for distribution in a national sexually transmitted infection (STI) AIDS prevention campaign in the Netherlands. The campaign material tested was the storyline of a planned television commercial on safe sex. A storyboard that consisted of drawings and text was presented to members of the target population, namely, students between the ages of 14 and 16 enrolled in vocational schools. Results showed positive effects on targeted determinants of safe sexual behavior. The advantages, practical implications, and limitations of experimental pretesting are discussed.

Hiding or hospitalising? On dilemmas of pregnancy management in East Cameroon.

PubMed

van der Sijpt, Erica

2013-01-01

Current international debates and policies on safe motherhood mainly propose biomedical interventions to reduce the risks during pregnancy and delivery. Yet, the conceptualisations of risk that underlie this framework may not correspond with local perceptions of reproductive dangers; consequently, hospital services may remain underutilised. Inspired by a growing body of anthropological literature exploring local fertility-related fears, and drawing on 15 months of fieldwork, this paper describes ideas about risky reproduction and practices of pregnancy protection in a Cameroonian village. It shows that social and supernatural threats to fertility are deemed more significant than the physical threats of fertility stressed at the (inter)national level. To protect their pregnancies from those social and supernatural influences, however, women take very physical measures. It is in this respect that biomedical interventions, physical in their very nature, do connect to local methods of pregnancy management. Furthermore, some pregnant women purposefully deploy hospital care in an attempt to reduce relational uncertainties. Explicit attention to the intersections of the social and the physical, and of the supernatural and the biomedical, furthers anthropological knowledge on fertility management and offers a starting point for more culturally sensitive safe motherhood interventions.

2017-05-01

By examining the relationship between trans identity, bathroom safety and wellbeing among high school students, this article empirically investigates how educational institutions operate as sites through which gender is negotiated in ways that are consequential for trans youth. We draw cross-sectional survey data, from a multi-school climate survey (n = 1046) conducted in the Midwestern United States, to examine three aspects of high school students' wellbeing: safety at school, self-esteem, and grades. The sample included students in 9th-12th grade who identified as trans (9.2%) and cisgender (41.2% boys, 49.6% girls), as well as LGBQ (21.6%) and heterosexual (78.4%). Most respondents were monoracial white (65.8%), monoracial Black (12.4%), and multiracial (14.1%). Using mediation and moderation linear regression models, we show that feeling safe using school facilities helps to explain widespread inequalities between trans and cisgender students. Based on these results, we suggest that in order to address disparities in educational outcomes between trans and cisgender students, as well as to improve student wellbeing in general, policies and practices need to ensure that all students have the right to safely access bathrooms and school facilities.

Urban poverty and utilization of maternal and child health care services in India.

Prakash, Ravi; Kumar, Abhishek

2013-07-01

Drawing upon data from the third round of the National Family Health Survey (NFHS-3) conducted in India during 2005-06, this study compares the utilization of selected maternal and child health care services between the urban poor and non-poor in India and across selected Indian states. A wealth index was created, separately for urban areas, using Principal Component Analysis to identify the urban poor. The findings suggest that the indicators of maternal and child health care are worse among the urban poor than in their non-poor counterparts. For instance, the levels of antenatal care, safe delivery and childhood vaccinations are much lower among the urban poor than non-poor, especially in socioeconomically disadvantageous states. Among all the maternal and child health care indicators, the non-poor/poor difference is most pronounced for delivery care in the country and across the states. Other than poverty status, utilization of antenatal services by mothers increases the chances of safe delivery and child immunization at both national and sub-national levels. The poverty status of the household emerged as a significant barrier to utilization of health care services in urban India.

Effective and Safe Use of Glucocorticosteroids for Rescue of Late ARDS

Diana, Paolo; Money, Dustin T.; Gelvin, Michael G.

2017-01-01

We describe a case of severe refractory hypoxemia requiring prolonged extra corporeal membrane oxygenation (ECMO) support in a case of postpartum acute respiratory distress syndrome (ARDS). The clinical course was marked by persistently poor lung compliance and several complications of ECMO, that is, significant hemolysis, hemothorax, and intracranial bleeding. We report marked improvement of lung mechanics and respiratory function, leading to accelerated separation from ECMO, following rescue administration of low dose methylprednisolone 24 days after the onset of ARDS. Corticosteroid treatment was safe and well tolerated. In contrast with the conclusions of the 2006 ARDS Network trial, our report establishes a case in support of the use of low dose methylprednisolone as a safe and effective rescue treatment option in selected subsets of patients with nonresolving ARDS.

Complementary and alternative medicine is used by a substantial number of pregnant women and maternity care providers are often faced with the task of ensuring women are using safe and effective treatments while respecting a woman's right to autonomous decision-making. In the era of evidence-based medicine maternity health professionals are expected to draw upon the best available evidence when making clinical decisions and providing health advice. This review will outline the current trends in research evidence associated with the outcomes of complementary and alternative medicine use amongst pregnant and birthing women as well as highlight some potential directions for future development in this important yet largely unknown topic in contemporary maternity care.

Life on the line: Job demands, perceived co-worker support for safety, and hazardous work events.

PubMed

Turner, Nick; Chmiel, Nik; Hershcovis, M Sandy; Walls, Melanie

2010-10-01

The present study of 334 United Kingdom trackside workers tested an interaction hypothesis. We hypothesized, drawing on the job demands-resources framework, that perceived support for safety (from senior managers, supervisors, and coworkers) as job resources would weaken the relationship between higher job demands and more frequent hazardous work events. Consistent with social impact theory, we predicted that perceived coworker support for safety would be particularly influential when trackside workers faced higher job demands. Moderated multiple regression showed that, of all three sources of perceived support for safety, perceived coworker support for safety was most important for keeping employees safe in the face of high job demands. © 2010 APA, all rights reserved.

Goldenhar syndrome: Cardiac anesthesiologist's perspective.

PubMed

Choudhury, Minati; Kapoor, Poonam Malhotra

2017-01-01

Goldenhar syndrome or oculo-auriculo-vertebral dysplasia was defined by Goldenhar in 1952 and redefined by Grolin et al. later. As the name denotes, children with this syndrome present with craniofacial and vertebral anomalies which increase the risk of airway compromise. Neonates and infants with this syndrome often have premature internal organs, low birth weight, and airway disorders. For this reason, safe anesthesia in such infants requires a complete knowledge regarding metabolism and side effects of the drugs. The association of cardiovascular abnormalities is not uncommon and possesses additional challenge for anesthetic management. The aim of this review is to draw attention to the various perioperative problems that can be faced in these infants when they undergo surgery or the correction of the underlying cardiac problem.

Television's impact on children.

PubMed

Zuckerman, D M; Zuckerman, B S

1985-02-01

Television has a major impact on children's knowledge, attitudes, and behavior. Research has demonstrated the association between television viewing and four areas: (1) children's aggressive behavior; (2) racial and sex-role stereotypes; (3) decreased interest in reading and school activities; and (4) poorer health habits and attitudes. Methodological limitations make it difficult to draw firm conclusions about a causal relationship between television viewing and children's behavior. Representative studies in these four areas are reviewed, important methodological concerns are pointed out, and conclusions from the research findings are drawn. The implications of the data for pediatricians and other health professionals are discussed.

Assessment of nerve involvement in the lumbar spine: agreement between magnetic resonance imaging, physical examination and pain drawing findings

PubMed Central

2010-01-01

Background Detection of nerve involvement originating in the spine is a primary concern in the assessment of spine symptoms. Magnetic resonance imaging (MRI) has become the diagnostic method of choice for this detection. However, the agreement between MRI and other diagnostic methods for detecting nerve involvement has not been fully evaluated. The aim of this diagnostic study was to evaluate the agreement between nerve involvement visible in MRI and findings of nerve involvement detected in a structured physical examination and a simplified pain drawing. Methods Sixty-one consecutive patients referred for MRI of the lumbar spine were - without knowledge of MRI findings - assessed for nerve involvement with a simplified pain drawing and a structured physical examination. Agreement between findings was calculated as overall agreement, the p value for McNemar's exact test, specificity, sensitivity, and positive and negative predictive values. Results MRI-visible nerve involvement was significantly less common than, and showed weak agreement with, physical examination and pain drawing findings of nerve involvement in corresponding body segments. In spine segment L4-5, where most findings of nerve involvement were detected, the mean sensitivity of MRI-visible nerve involvement to a positive neurological test in the physical examination ranged from 16-37%. The mean specificity of MRI-visible nerve involvement in the same segment ranged from 61-77%. Positive and negative predictive values of MRI-visible nerve involvement in segment L4-5 ranged from 22-78% and 28-56% respectively. Conclusion In patients with long-standing nerve root symptoms referred for lumbar MRI, MRI-visible nerve involvement significantly underestimates the presence of nerve involvement detected by a physical examination and a pain drawing. A structured physical examination and a simplified pain drawing may reveal that many patients with "MRI-invisible" lumbar symptoms need treatment aimed at nerve involvement. Factors other than present MRI-visible nerve involvement may be responsible for findings of nerve involvement in the physical examination and the pain drawing. PMID:20831785

Kozbelt, Aaron; Ostrofsky, Justin

2013-04-01

We discuss how the psycho-historical framework can be profitably applied to artistic production, facilitating a synthesis of perception-based and knowledge-based perspectives on realistic observational drawing. We note that artists' technical knowledge itself constitutes a major component of an artwork's historical context, and that links between artistic practice and psychological theory may yet yield conclusions in line with universalist perspectives.

Feingold, Alan

2017-01-01

The target article is a qualitative review of selected findings in the physical attractiveness literature. This commentary explains why the meta-analytic approach, frequently used by other attractiveness reviewers, is preferable for drawing unbiased conclusions about the effects of attractiveness. The article's main contribution is affording a foundation for subsequent meta-analysis of the studies discussed in a subjective fashion.

Critical thinking ability is an important part of educational goals. It has higher complex processes, such as analyzing, synthesizing and evaluating, drawing conclusion and reflection. This study is aimed to know the critical thinking ability of students in learning static fluids of senior high school students. This research uses the descriptive method which its instruments based on the indicator of critical thinking ability developed according to Ennis. The population of this research is XIth grade science class Public Senior High School, SMA N 1, Sambungmacan, Sragen, Central Java. The static fluid teaching material is delivered using Problem Based Learning Model through class experiment. The results of this study shows that the average student of XIth science class have high critical thinking skills, particularly in the ability of providing simple explanation, build basic skill, and provide advanced explanation, but they do not have high enough in ability of drawing conclusion and strategic and tactical components of critical thinking ability in the study of static fluid teaching material. The average of students critical thinking ability is 72.94, with 27,94% of students are in a low category and 72,22% of students in the high category of critical thinking ability.

Content and strategy in syllogistic reasoning.

PubMed

Marrero, Hipólito; Elena, Gámez

2004-09-01

Syllogistic reasoning has been investigated as a general deductive process (Johnson-Laird & Byrne, 1991; Revlis, 1975; Rips, 1994). However, several studies have demonstrated the role of cognitive strategies in this type of reasoning. These strategies focus on the method used by the participants (Ford, 1995; Gilhooly, Logie, Wetherick, & Wynn, 1993) and strategies related to different interpretations of the quantified premises (Roberts, Newstead, & Griggs, 2001). In this paper, we propose that content (as well as individual cognitive differences) is an important factor in inducing a certain strategy or method for syllogistic resolution. Specifically, we suggest that syllogisms with a causal conditional premise that can be extended by an agency premise induce the use of a conditional method. To demonstrate this, we carried out two experiments. Experiment 1 provided evidence that this type of syllogism leads participants to draw the predicted conditional conclusions, in contrast with control content syllogisms. In Experiment 2, we demonstrated that the drawing of conditional conclusions is based on a causal conditional to an agent representation of the syllogism premises. These results support the role of content as inducing a particular strategy for syllogistic resolution. The implications of these results are discussed.

R2R - software to speed the depiction of aesthetic consensus RNA secondary structures

PubMed Central

2011-01-01

Background With continuing identification of novel structured noncoding RNAs, there is an increasing need to create schematic diagrams showing the consensus features of these molecules. RNA structural diagrams are typically made either with general-purpose drawing programs like Adobe Illustrator, or with automated or interactive programs specific to RNA. Unfortunately, the use of applications like Illustrator is extremely time consuming, while existing RNA-specific programs produce figures that are useful, but usually not of the same aesthetic quality as those produced at great cost in Illustrator. Additionally, most existing RNA-specific applications are designed for drawing single RNA molecules, not consensus diagrams. Results We created R2R, a computer program that facilitates the generation of aesthetic and readable drawings of RNA consensus diagrams in a fraction of the time required with general-purpose drawing programs. Since the inference of a consensus RNA structure typically requires a multiple-sequence alignment, the R2R user annotates the alignment with commands directing the layout and annotation of the RNA. R2R creates SVG or PDF output that can be imported into Adobe Illustrator, Inkscape or CorelDRAW. R2R can be used to create consensus sequence and secondary structure models for novel RNA structures or to revise models when new representatives for known RNA classes become available. Although R2R does not currently have a graphical user interface, it has proven useful in our efforts to create 100 schematic models of distinct noncoding RNA classes. Conclusions R2R makes it possible to obtain high-quality drawings of the consensus sequence and structural models of many diverse RNA structures with a more practical amount of effort. R2R software is available at http://breaker.research.yale.edu/R2R and as an Additional file. PMID:21205310

The question about recommending pure, noncontaminated oats as part of the gluten-free diet of patients with celiac disease remains controversial. This might be due to gluten cross contamination and to the possible immunogenicity of some oat cultivars. In view of this controversy, a review of the scientific literature was conducted to highlight the latest findings published between 2008 and 2014 to examine the current knowledge on oats safety and celiac disease in Europe and North America. Results showed that regular oats consumed in Canada are largely contaminated. Overall, the consumption of pure oats has been generally considered to be safe for adults and children. However, it appears that some oat cultivars may trigger an immune response in sensitive individuals. Therefore, further long-term studies on the impact of consumption of oats identifying the cultivar(s) constitute an important step forward for drawing final recommendations. Furthermore, a closer and more accurate monitoring of the dietary intake of noncontaminated oats would be paramount to better determine what its actual contribution in the gluten-free diet of adults and children with celiac disease are in order to draw sound recommendations on the safety of pure oats as part of the gluten-free diet.

Making home visits: Creativity and the embodied practices of home visiting in social work and child protection.

PubMed

Ferguson, Harry

2018-01-01

Although the home is the most common place where social work goes on, research has largely ignored the home visit. Drawing on a participant observation study of child protection work, this article reveals the complex hidden practices of social work on home visits. It is argued that home visits do not simply involve an extension of the social work organisation, policies and procedures into the domestic domain but the home constitutes a distinct sphere of practice and experience in its own right. Home visiting is shown to be a deeply embodied practice in which all the senses and emotions come into play and movement is central. Through the use of creativity, craft and improvisation practitioners 'make' home visits by skilfully enacting a series of transitions from the office to the doorstep, and into the house, where complex interactions with service users and their domestic space and other objects occur. Looking around houses and working with children alone in their bedrooms were common. Drawing upon sensory and mobile methods and a material culture studies approach, the article shows how effective practice was sometimes blocked and also how the home was skilfully negotiated, moved around and creatively used by social workers to ensure parents were engaged with and children seen, held and kept safe.

Poole Wilson, Tiffany; Davis, Kermit G

2016-08-01

The aim of this study was to assess the contributions of Thomas Waters's work in the field of health care ergonomics and beyond. Waters's research of safe patient handling with a focus on reducing musculoskeletal disorders (MSDs) in health care workers contributed to current studies and prevention strategies. He worked with several groups to share his research and assist in developing safe patient handling guidelines and curriculum for nursing students and health care workers. The citations of articles that were published by Waters in health care ergonomics were evaluated for quality and themes of conclusions. Quality was assessed using the Mixed Methods Appraisal Tool and centrality to original research rating. Themes were documented by the type of population the citing articles were investigating. In total, 266 articles that referenced the top seven cited articles were evaluated. More than 95% of them were rated either medium or high quality. The important themes of these citing articles were as follows: (a) Safe patient handling is effective in reducing MSDs in health care workers. (b) Shift work has negative impact on nurses. (c) There is no safe way to manually lift a patient. (d) Nurse curriculums should contain safe patient handling. The research of Waters has contributed significantly to the health care ergonomics and beyond. His work, in combination with other pioneers in the field, has generated multiple initiatives, such as a standard safe patient-handling curriculum and safe patient-handling programs. © 2016, Human Factors and Ergonomics Society.

An in-depth analysis of pharmaceutical regulation in the Republic of Moldova

PubMed Central

2014-01-01

Objective Regulation of the pharmaceutical system is a crucial, yet often neglected, component in ensuring access to safe and effective medicines. The aim of this study was to provide an in-depth analysis of the existing pharmaceutical regulation, including recent changes, in the Republic of Moldova. Methods Data from field work conducted by the World Health Organization (WHO) together with a review of policy documents and quantitative secondary data analysis was used to achieve this aim. Results This analysis identified several ways in which pharmaceutical regulation affects availability of quality medicines in the Republic of Moldova. These include lack of full implementation bioequivalence requirements for generics registration, incomplete implementation of good manufacturing practices and no implementation of good distribution practices, use of quality control instead of quality assurance as a method to ensure quality of medicines, frequent change of power within the Medicines and Medical Devices Agency (MMDA) leading to lack of long-term strategy and plans, conflict of interest between the different functions of the MMDA, the lack of sufficient funding for the MMDA to conduct its activities and to invest in continuous training of its staff (particularly inspectors) and very weak post-marketing control. Notably, several improvements have been recently introduced, including a roadmap for change for the MMDA, the introduction of good manufacturing practices and the drafting of a quality manual for the Agency. Conclusion Based on these findings the authors propose a set of priority actions to address existing gaps and draw lessons learned from other countries. PMID:25848544

Peripheral Vasoconstriction and Abnormal Parasympathetic Response to Sighs and Transient Hypoxia in Sickle Cell Disease

Rationale: Sickle cell disease is an inherited blood disorder characterized by vasoocclusive crises. Although hypoxia and pulmonary disease are known risk factors for these crises, the mechanisms that initiate vasoocclusive events are not well known. Objectives: To study the relationship between transient hypoxia, respiration, and microvascular blood flow in patients with sickle cell. Methods: We established a protocol that mimics nighttime hypoxic episodes and measured microvascular blood flow to determine if transient hypoxia causes a decrease in microvascular blood flow. Significant desaturations were induced safely by five breaths of 100% nitrogen. Measurements and Main Results: Desaturation did not induce change in microvascular perfusion; however, it induced substantial transient parasympathetic activity withdrawal in patients with sickle cell disease, but not controls subjects. Marked periodic drops in peripheral microvascular perfusion, unrelated to hypoxia, were triggered by sighs in 11 of 11 patients with sickle cell and 8 of 11 control subjects. Although the sigh frequency was the same in both groups, the probability of a sigh inducing a perfusion drop was 78% in patients with sickle cell and 17% in control subjects (P < 0.001). Evidence for sigh-induced sympathetic nervous system dominance was seen in patients with sickle cell (P < 0.05), but was not significant in control subjects. Conclusions: These data demonstrate significant disruption of autonomic nervous system balance, with marked parasympathetic withdrawal in response to transient hypoxia. They draw attention to an enhanced autonomic nervous system–mediated sigh–vasoconstrictor response in patients with sickle cell that could increase red cell retention in the microvasculature, promoting vasoocclusion.

A potential impediment to evidence-based policy development on medical male circumcision (MC) for HIV prevention in all countries worldwide is the uncritical acceptance by some of arguments used by opponents of this procedure. Here we evaluate recent opinion-pieces of 13 individuals opposed to MC. We find that these statements misrepresent good studies, selectively cite references, some containing fallacious information, and draw erroneous conclusions. In marked contrast, the scientific evidence shows MC to be a simple, low-risk procedure with very little or no adverse long-term effect on sexual function, sensitivity, sensation during arousal or overall satisfaction. Unscientific arguments have been recently used to drive ballot measures aimed at banning MC of minors in the USA, eliminate insurance coverage for medical MC for low-income families, and threaten large fines and incarceration for health care providers. Medical MC is a preventative health measure akin to immunisation, given its protective effect against HIV infection, genital cancers and various other conditions. Protection afforded by neonatal MC against a diversity of common medical conditions starts in infancy with urinary tract infections and extends throughout life. Besides protection in adulthood against acquiring HIV, MC also reduces morbidity and mortality from multiple other sexually transmitted infections (STIs) and genital cancers in men and their female sexual partners. It is estimated that over their lifetime one-third of uncircumcised males will suffer at least one foreskin-related medical condition. The scientific evidence indicates that medical MC is safe and effective. Its favourable risk/benefit ratio and cost/benefit support the advantages of medical MC. PMID:22452415

Genetic Influences on Response to Alcohol and Response to Pharmacotherapies for Alcoholism

PubMed Central

Enoch, Mary-Anne

2014-01-01

Although very many individuals drink alcohol at safe levels, a significant proportion escalates their consumption with addiction as the end result. Alcoholism is a common, moderately heritable, psychiatric disorder that is accompanied by considerable morbidity and mortality. Variation in clinical presentation suggests inter-individual variation in mechanisms of vulnerability including genetic risk factors. The development of addiction is likely to involve numerous functional genetic variants of small effects. The first part of this review will focus on genetic factors underlying inter-individual variability in response to alcohol consumption, including variants in alcohol metabolizing genes that produce an aversive response (the flushing syndrome) and variants that predict the level of subjective and physiological response to alcohol. The second part of this review will report on genetic variants that identify subgroups of alcoholics who are more likely to respond to pharmacotherapy to reduce levels of drinking or maintain abstinence. Genetic analyses of the level of response to alcohol, particularly of the functional OPRM1 A118G polymorphism and 5′ and 3′ functional polymorphisms in SLC6A4, are beginning to provide insights into the etiology of alcoholism and also genotype-stratified subgroup responses to naltrexone and SSRIs / ondansetron respectively. Because of large inter-ethnic variation in allele frequencies, the relevance of these functional polymorphisms will vary between ethnic groups. However there are relatively few published studies in this field, particularly with large sample sizes in pharmacogenetic studies, therefore it is premature to draw any conclusions at this stage.

Early pregnancy failure (EPF) is a common complication of pregnancy. Surgical intervention carries a risk of complications and, therefore, medical treatment appears to be a safe alternative. Unfortunately, the current medical treatment with misoprostol alone has complete evacuation rates between 53% and 87%. Some reports suggest that sequential treatment with mifepristone and misoprostol leads to higher success rates than misoprostol alone. To evaluate the added value of mifepristone to current non-surgical treatment regimens in women with EPF we performed a systematic literature search. Electronic databases were searched: PubMed, Cochrane Library, Current Controlled Trials, and ClinicalTrials.gov. Clinical studies, both randomised and non-randomised trials, reporting on the added value of mifepristone to current non-surgical treatment regimens in women with EPF were included. Data of sixteen studies were extracted using a data extraction sheet (based on the Cochrane Consumers and Communication Review Group's data extraction template). The methodological quality was assessed using the Cochrane Collaboration Risk of Bias tool. In five randomised and eleven non-randomised trials, success rates of sequential treatment with mifepristone and misoprostol in case of EPF varied between 52% and 95%. Large heterogeneity existed in treatment regimens and comparators between studies. The existing evidence is insufficient to draw firm conclusions about the added value of mifepristone to misoprostol alone. A sufficiently powered randomised, double blinded placebo-controlled trial is urgently required to test whether, in EPF, the sequential combination of mifepristone with misoprostol is superior to misoprostol only.

International framework for examination of the cervical region for potential of Cervical Arterial Dysfunction prior to Orthopaedic Manual Therapy intervention.

PubMed

Rushton, A; Rivett, D; Carlesso, L; Flynn, T; Hing, W; Kerry, R

2014-06-01

A consensus clinical reasoning framework for best practice for the examination of the cervical spine region has been developed through an iterative consultative process with experts and manual physical therapy organisations. The framework was approved by the 22 member countries of the International Federation of Orthopaedic Manipulative Physical Therapists (October 2012). The purpose of the framework is to provide guidance to clinicians for the assessment of the cervical region for potential of Cervical Arterial Dysfunction in advance of planned management (inclusive of manual therapy and exercise interventions). The best, most recent scientific evidence is combined with international expert opinion, and is presented with the intention to be informative, but not prescriptive; and therefore as an aid to the clinician's clinical reasoning. Important underlying principles of the framework are that 1] although presentations and adverse events of Cervical Arterial Dysfunction are rare, it is a potentially serious condition and needs to be considered in musculoskeletal assessment; 2] manual therapists cannot rely on the results of one clinical test to draw conclusions as to the presence or risk of Cervical Arterial Dysfunction; and 3] a clinically reasoned understanding of the patient's presentation, including a risk:benefit analysis, following an informed, planned and individualised assessment, is essential for recognition of this condition and for safe manual therapy practice in the cervical region. Clinicians should also be cognisant of jurisdictionally specific requirements and obligations, particularly related to patient informed consent, when intending to use manual therapy in the cervical region.

Bernstein, Eric F; Bloom, Jason D; Basilavecchio, Lisa D; Plugis, Jessica M

2014-01-01

Background and Objectives A sharply contoured cryolipolysis vacuum applicator was developed to improve fit and tissue draw in the abdomen and flanks to better accommodate a range of body types and a variety of treatment sites. This study was carried out to evaluate the safety and efficacy of the new applicator for treatment of flank fat (“love handles”). Study Design/Materials and Methods A cryolipolysis vacuum applicator with a sharply contoured cup and curved cooling plates was used to treat 20 flanks. Two treatment cycles were delivered sequentially to each flank (60-minute cycle at a Cooling Intensity Factor of 41.6). Efficacy was evaluated 12 weeks post-treatment by physicians performing blinded, independent review of clinical photographs. Safety was assessed by the treating physician monitoring subjects for side effects and adverse events. Results Four blinded, independent physician reviewers properly identified the pre- and post-treatment photographs 94.4% of the time. Improvement was scored from 0 (none) to 10 (complete) and showed an average 4.3 point (43%) improvement. Side-effects were limited to erythema, edema, bruising, and numbness or tingling at the treatment site, and resolved without treatment. Conclusions Multiple treatment cycles from a new improved-fit cryolipolysis applicator are safe and effective for reduction of flank fat bulges. A high degree of improvement was reported by blinded, physician evaluation of standardized photographs. Laser Surg. Med. 46:731–735, 2014. © 2014 The Authors.

Seizures are a common presentation to pre-hospital emergency services and they generate significant healthcare costs. This article summarises the United Kingdom (UK) Ambulance Service guidelines for the management of seizures and explores the extent to which these guidelines are evidence-based. Summary of the Clinical Practice Guidelines of the UK Joint Royal Colleges Ambulance Liaison Committee relating to the management of seizures. Review of the literature relating to pre-hospital management of seizure emergencies. Much standard practice relating to the emergency out of hospital management of patients with seizures is drawn from generic Advanced Life Support (ALS) guidelines although many patients do not need ALS during or after a seizure and the benefit of many ALS interventions in seizure patients remains to be established. The majority of studies identified pertain to medical treatment of status epilepticus. These papers show that benzodiazepines are safe and effective but it is not possible to draw definitive conclusions about the best medication or the optimal route of administration. The evidence base for current pre-hospital guidelines for seizure emergencies is incomplete. A large proportion of patients are transported to hospital after a seizure but many of these may be suitable for home management. However, there is very little research into alternative care pathways or criteria that could be used to help paramedics avoid transport to hospital. More research is needed to improve care for people after a seizure and to improve the cost-effectiveness of the healthcare systems within which they are treated.

Magarian, Peggy; Sterling, Bernhard

2009-01-01

Introduction Four randomized controlled trials have compared mortality and morbidity of tight glycemic control versus conventional glucose for intensive care unit (ICU) patients. Two trials showed a positive outcome. However, one single-center trial and a large multicenter trial had negative results. The positive trials used accurate portable lab analyzers. The negative trial allowed the use of meters. The portable analyzer measures in filtered plasma, minimizing the interference effects. OptiScan Biomedical Corporation is developing a continuous glucose monitor using centrifuged plasma and mid-infrared spectroscopy for use in ICU medicine. The OptiScanner draws approximately 0.1 ml of blood every 15 min and creates a centrifuged plasma sample. Internal quality control minimizes sample preparation error. Interference adjustment using this technique has been presented at the Society of Critical Care Medicine in separate studies since 2006. Method A good laboratory practice study was conducted on three Yorkshire pigs using a central venous catheter over 6 h while performing a glucose challenge. Matching Yellow Springs Instrument glucose readings were obtained. Results Some 95.7% of the predicted values were in the Clarke Error Grid A zone and 4.3% in the B zone. Of those in the B zone, all were within 3.3% of the A zone boundaries. The coefficient of determination (R2) was 0.993. The coefficient of variance was 5.02%. Animal necropsy and blood panels demonstrated safety. Conclusion The OptiScanner investigational device performed safely and accurately in an animal model. Human studies using the device will begin soon. PMID:20144396

Background The level of traditional medicine use, particularly Jamu use, in Indonesia is substantial. Indonesians do not always seek timely treatment for malaria and may seek self-medication via traditional medicine. This paper reports findings from the first focused analyses of traditional medicine use for malaria in Indonesia and the first such analyses worldwide to draw upon a large sample of respondents across high-risk malaria endemic areas. Methods A sub-study of the Indonesia Basic Health Research/Riskesdas Study 2010 focused on 12,226 adults aged 15 years and above residing in high-risk malaria-endemic provinces. Logistic regression was undertaken to determine the significant associations for traditional medicine use for malaria symptoms. Findings Approximately one in five respondents use traditional medicine for malaria symptoms and the vast majority experiencing multiple episodes of malaria use traditional medicine alongside free antimalarial drug treatments. Respondents consuming traditional medicine for general health/common illness purposes every day (odds ratio: 3.75, 95% Confidence Interval: 2.93 4.79), those without a hospital in local vicinity (odds ratio: 1.31, 95% Confidence Interval: 1.10 1.57), and those living in poorer quality housing, were more likely to use traditional medicine for malaria symptoms. Conclusion A substantial percentage of those with malaria symptoms utilize traditional medicine for treating their malaria symptoms. In order to promote safe and effective malaria treatment, all providing malaria care in Indonesia need to enquire with their patients about possible traditional medicine use. PMID:28329019

Causal inference with missing exposure information: Methods and applications to an obstetric study.

2016-10-01

Causal inference in observational studies is frequently challenged by the occurrence of missing data, in addition to confounding. Motivated by the Consortium on Safe Labor, a large observational study of obstetric labor practice and birth outcomes, this article focuses on the problem of missing exposure information in a causal analysis of observational data. This problem can be approached from different angles (i.e. missing covariates and causal inference), and useful methods can be obtained by drawing upon the available techniques and insights in both areas. In this article, we describe and compare a collection of methods based on different modeling assumptions, under standard assumptions for missing data (i.e. missing-at-random and positivity) and for causal inference with complete data (i.e. no unmeasured confounding and another positivity assumption). These methods involve three models: one for treatment assignment, one for the dependence of outcome on treatment and covariates, and one for the missing data mechanism. In general, consistent estimation of causal quantities requires correct specification of at least two of the three models, although there may be some flexibility as to which two models need to be correct. Such flexibility is afforded by doubly robust estimators adapted from the missing covariates literature and the literature on causal inference with complete data, and by a newly developed triply robust estimator that is consistent if any two of the three models are correct. The methods are applied to the Consortium on Safe Labor data and compared in a simulation study mimicking the Consortium on Safe Labor. © The Author(s) 2013.

Wholesomeness of irradiated food

NASA Astrophysics Data System (ADS)

Ehlermann, Dieter A. E.

2016-12-01

Just with the emergence of the idea to treat food by ionizing radiation, the concerns were voiced whether it would be safe to consume such food. Now, we look back on more than hundred years of research into the 'wholesomeness', a terminology developed during those efforts. This review will cover the many questions which had been raised, explaining the most relevant ones in some detail; it will also give place to the concerns and elucidate their scientific relevance and background. There has never been any other method of food processing studied in such depth and in such detail as food irradiation. The conclusion based on science is: Consumption of any food treated at any high dose is safe, as long as the food remains palatable. This conclusion has been adopted by WHO, also by international and national bodies. Finally, this finding has also been adopted by Codex Alimentarius in 2003, the international standard for food. However, this conclusion has not been adopted and included at its full extent in most national regulations. As the literature about wholesomeness of irradiated food is abundant, this review will use only a few, most relevant references, which will guide the reader to further reading.

A decade ago, the Partnership for Maternal, Newborn and Child Health (PMNCH) was established to combat the growing fragmentation of global health action into uncoordinated, issue-specific efforts. Inspired by dominant global public-private partnerships for health, the PMNCH brought together previously competing advocacy coalitions for safe motherhood and child survival and attracted support from major donors, foundations and professional bodies. Today, its founders highlight its achievements in generating priority for 'MNCH', encouraging integrated health systems thinking and demonstrating the value of collaboration in global health endeavours. Against this dominant discourse on the success of the PMNCH, this article shows that rhetoric in support of partnership and integration often masks continued structural drivers and political dynamics that bias the global health field towards vertical goals. Drawing on ethnographic research, this article examines the Safe Motherhood Initiative's evolution into the PMNCH as a response to the competitive forces shaping the current global health field. Despite many successes, the PMNCH has struggled to resolve historically entrenched programmatic and ideological divisions between the maternal and child health advocacy coalitions. For the Safe Motherhood Initiative, the cost of operating within an extremely competitive policy arena has involved a partial renouncement of ambitions to broader social transformations in favour of narrower, but feasible and 'sellable' interventions. A widespread perception that maternal health remains subordinated to child health even within the Partnership has elicited self-protective responses from the safe motherhood contingent. Ironically, however, such responses may accentuate the kind of fragmentation to global health governance, financing and policy solutions that the Partnership was intended to challenge. The article contributes to the emerging critical ethnographic literature on global health initiatives by highlighting how integration may only be possible with a more radical conceptualization of global health governance. © The Author 2016.

Predicting water consumption habits for seven arsenic-safe water options in Bangladesh

PubMed Central

2013-01-01

Background In Bangladesh, 20 million people are at the risk of developing arsenicosis because of excessive arsenic intake. Despite increased awareness, many of the implemented arsenic-safe water options are not being sufficiently used by the population. This study investigated the role of social-cognitive factors in explaining the habitual use of arsenic-safe water options. Methods Eight hundred seventy-two randomly selected households in six arsenic-affected districts of rural Bangladesh, which had access to an arsenic-safe water option, were interviewed using structured face-to-face interviews in November 2009. Habitual use of arsenic-safe water options, severity, vulnerability, affective and instrumental attitudes, injunctive and descriptive norms, self-efficacy, and coping planning were measured. The data were analyzed using multiple linear regressions. Results Linear regression revealed that self-efficacy (B = 0.42, SE = .03, p < .001), the instrumental attitude towards the safe water option (B = 0.24, SE = .04, p < .001), the affective attitude towards contaminated tube wells (B = −0.04, SE = .02, p = .024), vulnerability (B = −0.20, SE = .02, p < .001), as well as injunctive (B = 0.08, SE = 0.04, p = .049) and descriptive norms (B = 0.34, SE = .03, p < .001) primarily explained the habitual use of arsenic-safe water options (R2 = 0.688). This model proved highly generalizable to all seven arsenic-safe water options investigated, even though habitual use of single options were predicted on the basis of parameters estimated without these options. Conclusions This general model for the habitual use of arsenic-safe water options may prove useful to predict other water consumption habits. Behavior-change interventions are derived from the model to promote the habitual use of arsenic-safe water options. PMID:23634950

SU-E-I-97: Smart Auto-Planning Framework in An EMR Environment (SAFEE)

DOE Office of Scientific and Technical Information (OSTI.GOV)

Zhang, B; Chen, S; Mutaf, Y

2014-06-01

Purpose: Our Radiation Oncology Department uses clinical practice guidelines for patient treatment, including normal tissue sparing and other dosimetric constraints. These practice guidelines were adapted from national guidelines, clinical trials, literature reviews, and practitioner's own experience. Modern treatment planning systems (TPS) have the capability of incorporating these practice guidelines to automatically create radiation therapy treatment plans with little human intervention. We are developing a software infrastructure to integrate clinical practice guidelines and radiation oncology electronic medical record (EMR) system into radiation therapy treatment planning system (TPS) for auto planning. Methods: Our Smart Auto-Planning Framework in an EMR environment (SAFEE) usesmore » a software pipeline framework to integrate practice guidelines,EMR, and TPS together. The SAFEE system starts with retrieving diagnosis information and physician's prescription from the EMR system. After approval of contouring, SAFEE will automatically create plans according to our guidelines. Based on clinical objectives, SAFEE will automatically select treatment delivery techniques (such as, 3DRT/IMRT/VMAT) and optimize plans. When necessary, SAFEE will create multiple treatment plans with different combinations of parameters. SAFEE's pipeline structure makes it very flexible to integrate various techniques, such as, Model-Base Segmentation (MBS) and plan optimization algorithms, e.g., Multi-Criteria Optimization (MCO). In addition, SAFEE uses machine learning, data mining techniques, and an integrated database to create clinical knowledgebase and then answer clinical questions, such as, how to score plan quality or how volume overlap affects physicians' decision in beam and treatment technique selection. Results: In our institution, we use Varian Aria EMR system and RayStation TPS from RaySearch, whose ScriptService API allows control by external programs. These applications are the building blocks of our SAFEE system. Conclusion: SAFEE is a feasible method of integrating clinical information to develop an auto-planning paradigm to improve clinical workflow in cancer patient care.« less

Background Recommendations call for the inclusion of both patient and provider input in the redesign of prescription labels. Pharmacist opinions on prescription warning labels are important because they are the health providers who would eventually distribute and explain the revised labels during medication counseling. They may be the first health provider to notice a patient's misunderstanding on how to safely use their prescription medications. Objectives To explore the perspectives of patients and pharmacists on five newly designed PWLs, and examine if there were similarities and differences between patients' and pharmacists' perspectives. Setting Private room in Wisconsin. Methods A descriptive study using semi-structured 60-min face-to-face individual interviews with patients and pharmacists explored patients and pharmacists' feedback on five newly designed PWLs. Patients who were 18 years and older, spoke English, and took a prescription medication and pharmacists who filled prescriptions in an ambulatory setting participated in the study. The patient and pharmacist perspectives on the words (content), picture and color (cosmetic appearance), and placement of warning instructions on the pill bottle (convenience) was based on a label redesign framework. Qualitative content analysis was done. Main outcome measure Patient and pharmacist perspectives on the newly designed PWLs. Results Twenty-one patients and eight pharmacists practicing in an academic medical center outpatient setting (n = 5) or retail pharmacy (n = 3) participated. All patients and pharmacists wanted the PWLs positioned on the front of the pill bottle but not the side of the bottle or warning instructions embedded into the main prescription label. Other similarities included participants preferring: (1) pictures closely depicting the instructions and (2) the use of yellow highlighting on the PWL to draw attention to it. There were differences in patient and pharmacist perspectives regarding the addition of 'Warning' to the instruction on the PWL with the patient preference to include the word 'Warning'. Pharmacists thought some PWL pictures had racial stereotypes, but this feedback was never mentioned by patients. Conclusions Patients and pharmacists had different preferences for PWL design changes to improve understandability. Pharmacist preferences did not always correspond with patient preferences. However, patients and pharmacists generally agreed on the preferred location of the PWL on the pill bottle and the use of color for drawing patients' attention.

Habitat Utilization Assessment - Building in Behaviors

NASA Technical Reports Server (NTRS)

Whitmore, Mihriban; Blume, Jennifer

2004-01-01

Habitability, and the associated architectural and design attributes of an environment, is a powerful performance shaping factor. By identifying how inhabitants use an area, we can draw conclusions about what design or architectural attributes cause what behaviors and systematically design in desired human performance. We are analyzing how a crew uses a long duration habitat and work environment during a four-day underwater mission and identifying certain architectural and design attributes that are related to, and potential enablers of, certain crew behaviors. By identifying how inhabitants use the habitat, we can draw conclusions about what habitability attributes cause what behaviors and systematically design in desired human performance (applicable to NASA's Bioastronautics Human Behavior and Performance Critical Path Roadmap question 6.12). This assessment replicates a methodology reported in a chapter titled "Sociokinetic Analysis as a Tool for Optimization of Environmental Design" by C. Adams.' That study collected video imagery of certain areas of a closed habitat during a 91 day test and from that data calculated time spent in different volumes during the mission, and characterized the behaviors occurring in certain habitat volumes thus concluding various rules for design of such habitats. This study assesses the utilization of the Aquarius Habitat, an underwater station, which will support six Aquanauts for a fourteen-day mission during which the crew will perform specific scientific and engineering studies. Video is recorded for long uninterrupted periods of time during the mission and from that data the time spent in each area is calculated. In addition, qualitative and descriptive analysis of the types of behaviors in each area is performed with the purpose of identifying any behaviors that are not typical of a certain area. If a participant uses an area in a way different from expected, a subsequent analysis of the features of that area may result in conclusions of performance shaping factors. With the addition of this study, we can make comparisons between the two different habitats and begin drawing correlation judgments about design features and behavior. Ideally, this methodology should be repeated in additional Aquarius missions and other analog environments because the real information will come from comparisons between habitats.

Gender identity and autism spectrum disorders.

van Schalkwyk, Gerrit I; Klingensmith, Katherine; Volkmar, Fred R

2015-03-01

In this review, we briefly summarize much of the existing literature on gender-related concerns and autism spectrum disorders (ASD), drawing attention to critical shortcomings in our current understanding and potential clinical implications. Some authors have concluded that gender identity disorder (GID), or gender dysphoria (GD), is more common in individuals with ASD, providing a range of potential explanations. However, existing literature is quantitatively limited, and our capacity to draw conclusions is further complicated by conceptual challenges regarding how gender identity is best understood. Discourses that emphasize gender as a component of identity formation are gaining prominence and seem particularly salient when applied to ASD. Individuals with ASD should enjoy equal rights with regard to treatment for gender dysphoria. Clinicians may be able to assist individuals in understanding this aspect of their identity by broadening the social frame and facilitating an exploration of gender roles.

A bottom-up strategy for establishment of EER in three Nordic countries - the role of networks

Edström, Kristina; Kolmos, Anette; Malmi, Lauri; Bernhard, Jonte; Andersson, Pernille

2018-03-01

This paper investigates the emergence of an engineering education research (EER) community in three Nordic countries: Denmark, Finland and Sweden. First, an overview of the current state of Nordic EER authorship is produced through statistics on international publication. Then, the history of EER and its precursor activities is described in three national narratives. These national storylines are tied together in a description of recent networking activities, aiming to strengthen the EER communities on the Nordic level. Taking these three perspectives together, and drawing on concepts from community of practice theory, network theory and learning network theory, we discuss factors behind the differences in the countries, and draw some conclusions about implications for networking activities in a heterogeneous community. Further, we discuss the role of networks for affording a joint identity.

Pushover, Response Spectrum and Time History Analyses of Safe Rooms in a Poor Performance Masonry Building

DOE Office of Scientific and Technical Information (OSTI.GOV)

Mazloom, M.

2008-07-08

The idea of safe room has been developed for decreasing the earthquake casualties in masonry buildings. The information obtained from the previous ground motions occurring in seismic zones expresses the lack of enough safety of these buildings against earthquakes. For this reason, an attempt has been made to create some safe areas inside the existing masonry buildings, which are called safe rooms. The practical method for making these safe areas is to install some prefabricated steel frames in some parts of the existing structure. These frames do not carry any service loads before an earthquake. However, if a devastating earthquakemore » happens and the load bearing walls of the building are destroyed, some parts of the floors, which are in the safe areas, will fall on the roof of the installed frames and the occupants who have sheltered there will survive. This paper presents the performance of these frames located in a destroying three storey masonry building with favorable conclusions. In fact, the experimental pushover diagram of the safe room located at the ground-floor level of this building is compared with the analytical results and it is concluded that pushover analysis is a good method for seismic performance evaluation of safe rooms. For time history analysis the 1940 El Centro, the 2003 Bam, and the 1990 Manjil earthquake records with the maximum peak accelerations of 0.35g were utilized. Also the design spectrum of Iranian Standard No. 2800-05 for the ground kind 2 is used for response spectrum analysis. The results of time history, response spectrum and pushover analyses show that the strength and displacement capacity of the steel frames are adequate to accommodate the distortions generated by seismic loads and aftershocks properly.« less

Abstract Background There have been many studies that evidence the health hazards of sunlight exposure, but less study on sun safe intervention model, especially in China. Our aim was to evaluate the cognitive and behavioral effects of a peer education model-based intervention to sun safe in children. Methods Cluster random control intervention was conducted in one district in Chongqing, China. Two primary schools, selected through stratified clustered sampling approach (two grades in each school, three classes in each grade) were designated as intervention (n=304) and control schools (n=305) randomly. 36 students, selected as peer educators in intervention group, were trained for one month. Educational activities such as discussions were organized by peer educator for one month. There was no sun safe education to participants in control school during the project period. The evaluation of changes of sun safe knowledge (the primary outcome), attitude and behavior (the secondary outcome measures) were conducted before intervention and at months of 0, 1 and 6 of the intervention to two groups using quantitative and qualitative methods. Results After the intervention, sun safe knowledge score which gained by the students from intervention group has been remarkably improved, compared to baseline survey (24.48±6.17 vs. 29.51±6.75) (P<0.001), and it kept this high level (29.02±7.96 and. 28.65±8.96), while control group students' scores have made no difference (P=0.410). Most of students have changed their sun safe behavior after the intervention. Conclusion Peer education program is somewhat effective in some dimensions for improving children's understanding of sun safe knowledge and behavior. PMID:25988089

ABSTRACT The Clock Drawing Test (CDT) is an important instrument for screening individuals suspected of having cognitive impairment. Objective: To determine the influence of education on the performance of healthy adults on the CDT. Methods: A total of 121 drawings by healthy adults without neurological complaints or impairments were analysed. Participants were stratified by educational level into 4 subgroups: 27 illiterate adults, 34 individuals with 1-4 years of formal education, 30 with 5-11 years, and 30 adults with >11 years' formal education. Scores on the CDT were analyzed based on a scale of 1-10 points according to the criteria of Sunderland et al. (1989).¹ The Kruskal-Wallis test was applied to compare the different education groups. Tukey's multiple comparisons test was used when a significant factor was found. Results: Although scores were higher with greater education, statistically significant differences on the CDT were found only between the illiterate and other educated groups. Conclusion: The CDT proved especially difficult for illiterate individuals, who had lower scores. These results suggest that this screening test is suitable for assessing mainly visuoconstructional praxis and providing an overall impression of cognitive function among individuals, independently of years of education.

Critical ionization velocity experiments in space

NASA Astrophysics Data System (ADS)

Lai, Shu T.; Murad, Edmond

1989-07-01

Space experiments to test the critical ionization velocity (CIV) theory have, on the whole, yielded negative results, with two notable exceptions. The results of all the experiments are analyzed with a view towards either optimizing or drawing conclusions about the conditions which lead to the propagation of CIV. In particular, four aspects of the conditions are considered: (1) beam injection angle with the ambient magnetic field in the ionosphere; (2) length of a CIV discharge region in a conical beam; (3) collisional ionization of the neutrals; and (4) chemiionization processes. The analysis leads to the conclusion that using the exhaust of the Shuttle engines may be the best way for testing CIV.

This paper identifies how the different ideologies of patriarchy, technology, capitalism, race and feminism shape how we see breastfeeding and the breastfeeding mother with child. Ultimately, while we can make good strong arguments for breastfeeding from the perspective of health, of outcome, of good scientific data, we need to appreciate that they are only rationalizations for a shared belief that the image of the breastfeeding woman with baby represents something precious and valuable. So while it may be important to make arguments that draw on what is valued in society, we need to think hard about what it is that we value so that as we move forward with our efforts to make breastfeeding safe, we can use but not be used by, the various ideologies or claims.

Lactobacillus acidophilus is a Gram-positive lactic acid bacterium that has had widespread historical use in the dairy industry and more recently as a probiotic. Although L. acidophilus has been designated as safe for human consumption, increasing commercial regulation and clinical demands for probiotic validation has resulted in a need to understand its genetic diversity. By drawing on large, well-characterised collections of lactic acid bacteria, we examined L. acidophilus isolates spanning 92 years and including multiple strains in current commercial use. Analysis of the whole genome sequence data set (34 isolate genomes) demonstrated L. acidophilus was a low diversity, monophyletic species with commercial isolates essentially identical at the sequence level. Our results indicate that commercial use has domesticated L. acidophilus with genetically stable, invariant strains being consumed globally by the human population. PMID:25425319

Although L. acidophilus has been designated as safe for human consumption, increasing commercial regulation and clinical demands for probiotic validation has resulted in a need to understand its genetic diversity. By drawing on large, well-characterised collections of lactic acid bacteria, we examined L. acidophilus isolates spanning 92 years and including multiple strains in current commercial use. Analysis of the whole genome sequence data set (34 isolate genomes) demonstrated L. acidophilus was a low diversity, monophyletic species with commercial isolates essentially identical at the sequence level. Our results indicate that commercial use has domesticated L. acidophilus with genetically stable, invariant strains being consumed globally by the human population.

A proposal for a simple and inexpensive therapeutic cancer vaccine.

PubMed

Fahrer, Aude M

2012-03-01

In this essay, I propose a new method of treating tumours, using an old and inexpensive preparation, that I contend would be of considerable benefit to patients and their cancer management. My rationale for this treatment initially arose from recent advances in the understanding of dendritic cell function. (Dendritic cells are key cells of the immune system that are able to either turn on or turn off T-cell responses.) Evidence to support this approach is found in 100-year-old studies on the immunotherapy of cancer. Also, I draw on some remarkable, but little-known studies from the 1960s-1990s, demonstrating that the preparation has already been trialled in humans (although not intratumourally, as I propose), and is considered sufficiently safe to proceed with clinical trials in cancer volunteers.

Introduction: For maintaining the continuity of care and improving the quality of care, effective inter-shift information communication is necessary. Any handover error can endanger patient safety. Despite the importance of shift handover, there is no standard handover protocol in our healthcare settings. Methods: In this one-group pretest-posttest quasi-experimental study conducted in spring and summer of 2011, we recruited a convenience sample of 56 ICU nurses. The Nurses’ Safe Practice Evaluation Checklist was used for data collection. The Content Validity Index and the inter-rater correlation coefficient of the checklist was 0.92 and 89, respectively. We employed the SPSS 11.5 software and the Mc Nemar and paired-samples t test for data analysis. Results: Study findings revealed that nurses’ mean score on the Safe Practice Evaluation Checklist increased significantly from 11.6 (2.7) to 17.0 (1.8) (P < 0.001). Conclusion: using a standard handover protocol for communicating patient’s needs and information improves nurses’ safe practice in the area of basic nursing care. PMID:25276725

Tranexamic acid for the management of uterine fibroid tumors: A systematic review of the current evidence

2014-01-01

AIM: To conduct a detailed systematic review of the current evidence on the administration and efficacy of tranexamic acid in patients with menorrhagia due to uterine fibroids. METHODS: We conducted an electronic search on the following databases PubMed and Medline (1950-2013); (1980-2013); Cochrane library (1993-2013). RESULTS: A total of 36 articles were retrieved after the initial electronic search. Careful assessment of the retrieved studies led to the final selection of 5 articles for inclusion in the review. CONCLUSION: Tranexamic acid may reduce blood loss perioperatively in myomectomies. It may reduce the menorrhagia in patients with fibroids, however a stratification of fibroids by size and location is required to define the responses. It is safe in general, with mild adverse effects observed in some cases. More studies with a double-blind randomized design and larger numbers of participants are necessary to reach more precise and safe conclusions. PMID:25516866

This study is aimed at definition of the safe and dangerous zone for screw placement with Stoppa approach for rapid identification during operation and a new way for the studies on the “safe zone.” Pelvic CT data of 84 human subjects were recruited to reconstruct the three-dimensional (3D) models. The distances between the edges of the “safe zone,” “dangerous zone,” and specific anatomic landmarks such as the obturator canal and the pelvic brim were precisely measured, respectively. The results show that the absolute “dangerous zone” was from the pelvic brim to 3.07 cm below it and within 2.86 cm of the obturator canal, while the region 3.56 cm below the pelvic brim or 3.85 cm away from the obturator canal was the absolute “safe zone” for screw placement. The region between the absolute “safe zone” and the absolute “dangerous zone” was the relatively “dangerous zone.” As a conclusion, application of computer-assisted 3D modeling techniques aids in the precise measurement of “safe zone” and “dangerous zone” in combination with Stoppa incision. It was not recommended to place screws on the absolute dangerous zone, while, for the relatively “dangerous zone,” it depends on the individual variations in bony anatomy and the fracture type.

Abstract Objective To determine how data on water source quality affect assessments of progress towards the 2015 Millennium Development Goal (MDG) target on access to safe drinking-water. Methods Data from five countries on whether drinking-water sources complied with World Health Organization water quality guidelines on contamination with thermotolerant coliform bacteria, arsenic, fluoride and nitrates in 2004 and 2005 were obtained from the Rapid Assessment of Drinking-Water Quality project. These data were used to adjust estimates of the proportion of the population with access to safe drinking-water at the MDG baseline in 1990 and in 2008 made by the Joint Monitoring Programme for Water Supply and Sanitation, which classified all improved sources as safe. Findings Taking account of data on water source quality resulted in substantially lower estimates of the percentage of the population with access to safe drinking-water in 2008 in four of the five study countries: the absolute reduction was 11% in Ethiopia, 16% in Nicaragua, 15% in Nigeria and 7% in Tajikistan. There was only a slight reduction in Jordan. Microbial contamination was more common than chemical contamination. Conclusion The criterion used by the MDG indicator to determine whether a water source is safe can lead to substantial overestimates of the population with access to safe drinking-water and, consequently, also overestimates the progress made towards the 2015 MDG target. Monitoring drinking-water supplies by recording both access to water sources and their safety would be a substantial improvement. PMID:22461718

AIM: To investigate the effectiveness of head compensatory postures to ensure safe oropharyngeal transit. METHODS: A total of 321 dysphagia patients were enrolled and assessed with videofluoromanometry (VFM). The dysphagia patients were classified as follows: safe transit; penetration without aspiration; aspiration before, during or after swallowing; multiple aspirations and no transit. The patients with aspiration or no transit were tested with VFM to determine whether compensatory postures could correct their swallowing disorder. RESULTS: VFM revealed penetration without aspiration in 71 patients (22.1%); aspiration before swallowing in 17 patients (5.3%); aspiration during swallowing in 32 patients (10%); aspiration after swallowing in 21 patients (6.5%); multiple aspirations in six patients (1.9%); no transit in five patients (1.6%); and safe transit in 169 patients (52.6%). Compensatory postures guaranteed a safe transit in 66/75 (88%) patients with aspiration or no transit. A chin-down posture achieved a safe swallow in 42/75 (56%) patients, a head-turned posture in 19/75 (25.3%) and a hyperextended head posture in 5/75 (6.7%). The compensatory postures were not effective in 9/75 (12%) cases. CONCLUSION: VFM allows the speech-language the-rapist to choose the most effective compensatory posture without a trial-and-error process and check the effectiveness of the posture. PMID:22736921

2018-01-01

Background Cultural safety has the potential to improve the health disparities between Indigenous and non-Indigenous Canadians, yet practical applications of the concept are lacking in the literature. Purpose This study aims to identify the key components of culturally safe health initiatives for the Indigenous population of Canada to refine its application in health-care settings. Methods We conducted a scoping review of the literature pertaining to culturally safe health promotion programs, initiatives, services, or care for the Indigenous population in Canada. Our initial search yielded 501 publications, but after full review of 44 publications, 30 were included in the review. After charting the data, we used thematic analysis to identify themes in the data. Results We identified six themes: collaboration/partnerships, power sharing, address the broader context of the patient's life, safe environment, organizational and individual level self-reflection, and training for health-care providers. Conclusion While it is important to recognize that the provision of culturally safe initiatives depend on the specific interaction between the health-care provider and the patient, having a common understanding of the components of cultural safety, such as those that we identified through this research, will help in the transition of cultural safety from theory into practice.

Adolescent drivers: a developmental perspective on risk, proficiency, and safety.

2008-09-01

Despite considerable improvement in the rates of crashes, injuries, and fatalities among adolescent drivers, attributable in part to effective interventions such as graduated driver licensing, these rates and their associated health risks remain unacceptably high. To understand the sources of risky driving among teens, as well as to identify potential avenues for further advances in prevention, this article presents a review of the relevant features of contemporary research on adolescent development. Current research offers significant advances in the understanding of the sources of safe driving, proficient driving, and risky driving among adolescents. This multifaceted perspective--as opposed to simple categorization of good versus bad driving--provides new opportunities for using insights on adolescent development to enhance prevention. Drawing on recent work on adolescent physical, neural, and cognitive development, we argue for approaches to prevention that recognize both the strengths and the limitations of adolescent drivers, with particular attention to the acquisition of expertise, regulatory competence, and self-regulation in the context of perceived risk. This understanding of adolescent development spotlights the provision of appropriate and effective scaffolding, utilizing the contexts of importance to adolescents--parents, peers, and the broader culture of driving--to support safe driving and to manage the inherent risks in learning to do so.

Objective: This systematic review examined whether radiofrequency ablation (RFA) is a safe treatment modality for benign thyroid nodules (BTNs). Data Sources: PubMed, Embase, and the Cochrane Library database were searched for articles that (a) targeted human beings and (b) had a study population with BTNs that were confirmed by fine-needle aspiration cytology and/or core needle biopsy. Study Selection: Thirty-two studies relating to 3409 patients were included in this systematic review. Results: Based on literatures, no deaths were associated with the procedure, serious complications were rare, and RFA appears to be a safe and well-tolerated treatment modality. However, a broad spectrum of complications offers insights into some undesirable complications, such as track needle seeding and Horner syndrome. Conclusions: RFA appears to be a safe and well-tolerated treatment modality for BTNs. More research is needed to characterize the complications of RFA for thyroid nodules. PMID:28524837

Aim Developing strategies to ensure the safe participation of people with dementia in research is critical to support their wider inclusion in research and to advance knowledge in the areas of dementia policy and practice. Objectives This literature review synthesizes and critically appraises different approaches to promote the safe participation of people with dementia in qualitative research. Methods Two databases were searched for articles that discuss the methodological or ethical aspects of qualitative research involving people with dementia. We did not focus on informed consent or ethical review processes as these have been reviewed elsewhere. Findings Key issues that impact participant safety include: language, gatekeepers, the research relationship, communication, dealing with distress, knowledge dissemination, and researcher skills. Conclusion By synthesizing different approaches to safety and highlighting areas of debate, we hope to advance discussion and to contribute to the development of inclusive research methods.

Guidelines and Recommendations for Developing Interactive eHealth Apps for Complex Messaging in Health Promotion

2016-01-01

Background The now ubiquitous catchphrase, “There’s an app for that,” rings true owing to the growing number of mobile phone apps. In excess of 97,000 eHealth apps are available in major app stores. Yet the effectiveness of these apps varies greatly. While a minority of apps are developed grounded in theory and in conjunction with health care experts, the vast majority are not. This is concerning given the Hippocratic notion of “do no harm.” There is currently no unified formal theory for developing interactive eHealth apps, and development is especially difficult when complex messaging is required, such as in health promotion and prevention. Objective This paper aims to provide insight into the creation of interactive eHealth apps for complex messaging, by leveraging the Safe-D case study, which involved complex messaging required to guide safe but sufficient UV exposure for vitamin D synthesis in users. We aim to create recommendations for developing interactive eHealth apps for complex messages based on the lessons learned during Safe-D app development. Methods For this case study we developed an Apple and Android app, both named Safe-D, to safely improve vitamin D status in young women through encouraging safe ultraviolet radiation exposure. The app was developed through participatory action research involving medical and human computer interaction researchers, subject matter expert clinicians, external developers, and target users. The recommendations for development were created from analysis of the development process. Results By working with clinicians and implementing disparate design examples from the literature, we developed the Safe-D app. From this development process, recommendations for developing interactive eHealth apps for complex messaging were created: (1) involve a multidisciplinary team in the development process, (2) manage complex messages to engage users, and (3) design for interactivity (tailor recommendations, remove barriers to use, design for simplicity). Conclusions This research has provided principles for developing interactive eHealth apps for complex messaging as guidelines by aggregating existing design concepts and expanding these concepts and new learnings from our development process. A set of guidelines to develop interactive eHealth apps generally, and specifically those for complex messaging, was previously missing from the literature; this research has contributed these principles. Safe-D delivers complex messaging simply, to aid education, and explicitly, considering user safety. PMID:26860623

Developing Social Media-Based Suicide Prevention Messages in Partnership With Young People: Exploratory Study

2017-01-01

Background Social media is increasingly being used by young people for health-related issues, including communicating about suicide. Due to the concerns about causing distress or inducing suicidal thoughts or behaviors, to date young people neither have been engaged in the development of social media–based suicide prevention interventions nor have interventions focused on educating young people about safe ways to communicate about suicide online. Given the potential that social media holds to deliver messages to vast numbers of people across space and time and the fact that young people often prefer to seek help from their friends and peers, safely educating and engaging young people to develop suicide prevention messages that can be delivered via social media is an obvious next step. Objectives The objectives of this study were to (1) provide education to a small number of secondary school students about safe ways to communicate about suicide via social media; (2) engage the same young people in the development of a suite of social media–based suicide prevention multimedia messages; (3) assess the impact of this on participants; and (4) assess the acceptability and safety of the messages developed. Methods This study involved two phases. In phase 1, 20 participants recruited from two schools took part in an 8- to 10-week program during which they were provided with psychoeducation about mental health and suicide, including how to talk safely about suicide online, and they were then supported to design and develop their own media messages. These participants completed an evaluation questionnaire at the conclusion of the program. In phase 2, a larger group of participants (n=69), recruited via an opt-in process, viewed the media messages and completed a short questionnaire about each one. Results Participants in phase 1 enjoyed the program and reported that they learned new skills, such as how to talk safely about suicide online, and felt more able to provide emotional support to others (16/20, 80%). No participants reported that the program made them feel suicidal. Participants in phase 2 generally rated the media messages as safe and acceptable, although some messages were rated more highly than others. Conclusions This study suggests that young people can be safely engaged in developing suicide prevention messages, which can be disseminated via social media. Engaging young people in this process may improve the traction that such campaigns will have with other young people. The study also suggests that educating young people regarding how to talk safely about suicide online has multiple benefits and is not associated with distress. Overall, these findings pave the way for new approaches to prevent suicide among young people. PMID:28978499

The impact of scienceware and foundations on students' attitudes towards science and science classes

NASA Astrophysics Data System (ADS)

Stratford, Steven J.; Finkel, Elizabeth A.

1996-03-01

In this paper, we describe changes in students' ideas about science classes, attitudes about science, and motivations for studying science, in a classroom designed to support projectbased science learing. Using a survey designed to provide a measure of students' attitudes towards science classes and science, we have compared students enrolled in a traditional high school biology course, with students enrolled in an integrated, project-based science course called Foundations I. Survey responses were analyzed to look at differences between and within two groups of students over the course of one school year. In general, the results of this study suggest that providing students with opportunities to collect and analyze their own data in science classes results in a change in students' ideas about science classrooms. Foundations I students' increased tendency to agree with statements about `using information,' `drawing conclusions,' and `thinking about problems,' implies a change in their understanding of what it means to do science in school. These students, in contrast to students in the traditional Biology course, no longer describe their science experience as one of memorization, textbook reading, and test taking. Instead they see science class as a place in which they can collect data, draw conclusions, and formulate and solve problems.

Adenomyosis: a life-cycle approach.

PubMed

Benagiano, Giuseppe; Brosens, Ivo; Habiba, Marwan

2015-03-01

The life-cycle approach to endometriosis highlighted unexpected features of the condition; the same approach was therefore applied to gain insight into the clinical features of adenomyosis and to draw a comparison with endometriosis. This is possible today thanks to new imaging techniques enabling non-invasive diagnosis of adenomyosis. The specificity and sensitivity of magnetic resonance imaging and transvaginal ultrasound remain uncertain. Unlike endometriosis, little information is available on the presence of classic adenomyosis in adolescents, except for rare cystic forms that may not represent the true disease. Adenomyosis is most likely to affect adult women, although most reported incidences are still based on post-hysterectomy studies, and are affected by diligence in histopathologic diagnosis and the adopted cut-off point. The traditionally accepted associations of adult adenomyosis, such as multiparity, a link to infertility and its effect on pregnancy are uncertain. Active adenomyosis has been found in pre- and peri-menopausal women and in postmenopausal women receiving tamoxifen. In conclusion, major diagnostic limitations and the systematic bias of hysterectomy make it difficult to draw firm conclusions from existing evidence. In addition, no information is available on the natural history of adenomyosis and no study has systematically evaluated its existence in adolescents. Copyright © 2014 Reproductive Healthcare Ltd.

Controversies relating to the management of acromioclavicular joint dislocations.

2013-12-01

The aim of this review is to address controversies in the management of dislocations of the acromioclavicular joint. Current evidence suggests that operative rather than non-operative treatment of Rockwood grade III dislocations results in better cosmetic and radiological results, similar functional outcomes and longer time off work. Early surgery results in better functional and radiological outcomes with a reduced risk of infection and loss of reduction compared with delayed surgery. Surgical options include acromioclavicular fixation, coracoclavicular fixation and coracoclavicular ligament reconstruction. Although non-controlled studies report promising results for arthroscopic coracoclavicular fixation, there are no comparative studies with open techniques to draw conclusions about the best surgical approach. Non-rigid coracoclavicular fixation with tendon graft or synthetic materials, or rigid acromioclavicular fixation with a hook plate, is preferable to fixation with coracoclavicular screws owing to significant risks of loosening and breakage. The evidence, although limited, also suggests that anatomical ligament reconstruction with autograft or certain synthetic grafts may have better outcomes than non-anatomical transfer of the coracoacromial ligament. It has been suggested that this is due to better restoration horizontal and vertical stability of the joint. Despite the large number of recently published studies, there remains a lack of high-quality evidence, making it difficult to draw firm conclusions regarding these controversial issues.

2017-08-01

To inform regulatory decisions on the risk due to exposure to ambient air pollution, consistent and transparent communication of the scientific evidence is essential. The United States Environmental Protection Agency (U.S. EPA) develops the Integrated Science Assessment (ISA), which contains evaluations of the policy-relevant science on the effects of criteria air pollutants and conveys critical science judgments to inform decisions on the National Ambient Air Quality Standards. This article discusses the approach and causal framework used in the ISAs to evaluate and integrate various lines of scientific evidence and draw conclusions about the causal nature of air pollution-induced health effects. The framework has been applied to diverse pollutants and cancer and noncancer effects. To demonstrate its flexibility, we provide examples of causality judgments on relationships between health effects and pollutant exposures, drawing from recent ISAs for ozone, lead, carbon monoxide, and oxides of nitrogen. U.S. EPA's causal framework has increased transparency by establishing a structured process for evaluating and integrating various lines of evidence and uniform approach for determining causality. The framework brings consistency and specificity to the conclusions in the ISA, and the flexibility of the framework makes it relevant for evaluations of evidence across media and health effects.

Unicomb, Leanne; Arnold, Benjamin F.; Colford Jr., John M.; Luby, Stephen P.

2015-01-01

Background Shallow tubewells are the primary drinking water source for most rural Bangladeshis. Fecal contamination has been detected in tubewells, at low concentrations at the source and at higher levels at the point of use. We conducted a randomized controlled trial to assess whether improving the microbiological quality of tubewell drinking water by household water treatment and safe storage would reduce diarrhea in children <2 years in rural Bangladesh. Methods We randomly assigned 1800 households with a child aged 6-18 months (index child) into one of three arms: chlorine plus safe storage, safe storage and control. We followed households with monthly visits for one year to promote the interventions, track their uptake, test participants’ source and stored water for fecal contamination, and record caregiver-reported child diarrhea prevalence (primary outcome). To assess reporting bias, we also collected data on health outcomes that are not expected to be impacted by our interventions. Findings Both interventions had high uptake. Safe storage, alone or combined with chlorination, reduced heavy contamination of stored water. Compared to controls, diarrhea in index children was reduced by 36% in the chlorine plus safe storage arm (prevalence ratio, PR = 0.64, 0.55-0.73) and 31% in the safe storage arm (PR = 0.69, 0.60-0.80), with no difference between the two intervention arms. One limitation of the study was the non-blinded design with self-reported outcomes. However, the prevalence of health outcomes not expected to be impacted by water interventions did not differ between study arms, suggesting minimal reporting bias. Conclusions Safe storage significantly improved drinking water quality at the point of use and reduced child diarrhea in rural Bangladesh. There was no added benefit from combining safe storage with chlorination. Efforts should be undertaken to implement and evaluate long-term efforts for safe water storage in Bangladesh.

Sucralose is a non-nutritive sweetener used in a broad range of foods and beverages and is the non-nutritive sweetener in retail SPLENDA Sweetening Products, composed of sucralose and common food ingredients. A review of the extensive body of evidence that supports the safety of sucralose is provided. The results of an independent review of a new study investigating the safety of a sucralose-mixture retail product, Granulated SPLENDA No Calorie Sweetener, are also discussed. The collective evidence supports the conclusion that the ingredient, sucralose, is safe for use in food and that the sucralose-mixture product, Granulated SPLENDA No Calorie Sweetener, is also safe for its intended use.

Broken Robustness Analysis: How to make proper climate change conclusions in contradictory multimodal measurement contexts.

NASA Astrophysics Data System (ADS)

Keyser, V.

2015-12-01

Philosophers of science discuss how multiple modes of measurement can generate evidence for the existence and character of a phenomenon (Horwich 1982; Hacking 1983; Franklin and Howson 1984; Collins 1985; Sober 1989; Trout 1993; Culp 1995; Keeley 2002; Staley 2004; Weber 2005; Keyser 2012). But how can this work systematically in climate change measurement? Additionally, what conclusions can scientists and policy-makers draw when different modes of measurement fail to be robust by producing contradictory results? First, I present a new technical account of robust measurement (RAMP) that focuses on the physical independence of measurement processes. I detail how physically independent measurement processes "check each other's results." (This account is in contrast to philosophical accounts of robustness analysis that focus on independent model assumptions or independent measurement products or results.) Second, I present a puzzle about contradictory and divergent climate change measures, which has consistently re-emerged in climate measurement. This discussion will focus on land, drilling, troposphere, and computer simulation measures. Third, to systematically solve this climate measurement puzzle, I use RAMP in the context of drought measurement in order to generate a classification of measurement processes. Here, I discuss how multimodal precipitation measures—e.g., measures of precipitation deficit like the Standard Precipitation Index vs. air humidity measures like the Standardized Relative Humidity Index--can help with the classification scheme of climate change measurement processes. Finally, I discuss how this classification of measures can help scientists and policy-makers draw effective conclusions in contradictory multimodal climate change measurement contexts.

Solid evidence of treatment effects in older women with breast cancer is lacking, as they are generally underrepresented in randomized clinical trials on which guideline recommendations are based. An alternative way to study treatment effects in older patients could be to use data from observational studies. However, using appropriate methods in analyzing observational data is a key condition in order to draw valid conclusions, as directly comparing treatments generally results in biased estimates due to confounding by indication. The aim of this systematic review was to investigate the methods that have been used in observational studies that assessed the effects of breast cancer treatment on survival, breast cancer survival and recurrence in older patients (aged 65 years and older). Studies were identified through systematic review of the literature published between January 1st 2009 and December 13th 2013 in the PubMed database and EMBASe. Finally, 31 studies fulfilled the inclusion criteria. Of these, 22 studies directly compared two treatments. Fifteen out of these 22 studies addressed the problem of confounding by indication, while seven studies did not. Nine studies used some form of instrumental variable analysis. In conclusion, the vast majority of observational studies that investigate treatment effects in older breast cancer patients compared treatments directly. These studies are therefore likely to be biased. Observational research will be essential to improve treatment and outcome of older breast cancer patients, but the use of accurate methods is essential to draw valid conclusions from this type of data.

‘It is not expected for married couples’: a qualitative study on challenges to safer sex communication among polygamous and monogamous partners in southeastern Tanzania

PubMed Central

Mtenga, Sally Mmanyi; Geubbels, Eveline; Tanner, Marcel; Merten, Sonja; Pfeiffer, Constanze

2016-01-01

Background Behavioral change approaches for human immunodeficiency virus (HIV) prevention in Tanzania encourage married partners to observe safe sex practices (condom use, avoidance of, or safe sex with multiple partners). To implement this advice, partners need to communicate with each other about safer sex, which is often challenging. Although social-structural factors are crucial in understanding sexual behavior, only a few studies focus on understanding safer sex dialogue in a broader social context. Design Drawing on the WHO-Commission on the Social Determinants of Health (WHO-CSDH) framework, this study explored key social-structural constructs for studying health in the context of improving safer sex dialogue between polygamous and monogamous partners. Twenty-four in-depth interviews (IDIs) and six focus group discussions (FGDs) with 38 men and women aged 18–60 years were conducted in Ifakara town located in Kilombero district, Tanzania. The study was nested within the community health surveillance project MZIMA (Kiswahili: ‘being healthy’). Partners’ experiences of safer sex dialogue in polygamous and monogamous relations were investigated and the challenges to safer sex dialogue explored. Results The study revealed that open safer sex dialogue in marriage is limited and challenged by social norms about marriage (a view that safer sex dialogue imply that partners are ‘not really’ married); marital status (a belief that safer sex dialogue is not practical in polygamous marriages, the elder wife should be exempted from the dialogue since she is at lower risk of engaging in extramarital affairs); relationship quality (marital conflicts, extramarital affairs, trust, and sexual dissatisfaction); and gender power relations (the notion that females’ initiative to discuss condom use and HIV couple counseling and testing may lead to conflict or divorce). Conclusions Implementing safer sex practices requires interventions beyond promotion messages. HIV prevention interventions in Tanzania should be carefully adapted to the local context including respective social norms, gender systems, marital context and relationship uncertainties as aspects that facilitate or hinder safer sex dialogue between partners. The WHO-CSDH framework could be strengthened by explicitly integrating relationship quality, marital status, and social norms as additional determinants of health. PMID:27633036

Resilience 2.0: social media use and (self-)care during the 2011 Norway attacks

2015-01-01

Departing from the understanding that resilience is a technique of self-organization during emergencies, this article provides a study on the way in which the use of social media influenced and engendered societal resilience practices during the 2011 Norway attacks. It builds on the concepts of governmentality and mediality to discuss how the interplay between social media and its users created new forms of self-initiated and mediated emergency governance. Empirically, it draws on material from 20 in-depth interviews with Norwegians who explained and reflected upon their social media use during the attacks. The article presents an overview of the different functions that social media assumed in the process of dealing with the attacks and discusses these vis-à-vis their related challenges. It draws conclusions about the way in which resilience practices and the resilient subject are influenced by the networked character of 2.0 technologies. PMID:29708120

Gender Identity and Autism Spectrum Disorders

van Schalkwyk, Gerrit I.; Klingensmith, Katherine; Volkmar, Fred R.

2015-01-01

In this review, we briefly summarize much of the existing literature on gender-related concerns and autism spectrum disorders (ASD), drawing attention to critical shortcomings in our current understanding and potential clinical implications. Some authors have concluded that gender identity disorder (GID), or gender dysphoria (GD), is more common in individuals with ASD, providing a range of potential explanations. However, existing literature is quantitatively limited, and our capacity to draw conclusions is further complicated by conceptual challenges regarding how gender identity is best understood. Discourses that emphasize gender as a component of identity formation are gaining prominence and seem particularly salient when applied to ASD. Individuals with ASD should enjoy equal rights with regard to treatment for gender dysphoria. Clinicians may be able to assist individuals in understanding this aspect of their identity by broadening the social frame and facilitating an exploration of gender roles. PMID:25744543

Obesogenic environments: environmental approaches to obesity prevention.

Lipek, Tobias; Igel, Ulrike; Gausche, Ruth; Kiess, Wieland; Grande, Gesine

2015-05-01

Childhood obesity is a major concern for public health. There are multiple factors (e.g., genetic, social, and environmental) that contribute to unhealthy weight gain. Drawing from findings on "obesogenic environments" and core principles of preventive strategies to reduce health inequalities, this paper gives an overview of recent childhood prevention programs that target aspects of the physical environment ("environmental changes"). Out of the ten reviews we screened (including more than 300 studies), we identified very few that addressed aspects of the environment. We focus here on 14 programs that follow different approaches to environmental changes (e.g., access to/quality of playgrounds, changes in school cafeterias). Altering the environment offers opportunities for healthier behaviors and seems to be an effective strategy to prevent childhood obesity. However, the evaluation of those (mostly) multidimensional interventions does not allow drawing firm conclusions about the single effect of environmental changes. We conclude that obesity prevention programs should combine person-based and environmental approaches.

Why consent may not be needed for organ procurement.

PubMed

Delaney, James; Hershenov, David B

2009-08-01

Most people think it is wrong to take organs from the dead if the potential donors had previously expressed a wish not to donate. Yet people respond differently to a thought experiment that seems analogous in terms of moral relevance to taking organs without consent. We argue that our reaction to the thought experiment is most representative of our deepest moral convictions. We realize not everyone will be convinced by the conclusions we draw from our thought experiment. Therefore, we point out that the state ignores consent in performing mandatory autopsies in some cases. If readers are willing to give up the permissibility of mandatory autopsies, we then offer some metaphysical arguments against posthumous harm. Drawing upon claims about bodies ceasing to exist at death and Epicurean-inspired arguments against posthumous interests, we make a case for an organ conscription policy which respects fundamental liberal principles of autonomy, bodily integrity, and property.

Convex Arrhenius plots and their interpretation

PubMed Central

Truhlar, Donald G.; Kohen, Amnon

2001-01-01

This paper draws attention to selected experiments on enzyme-catalyzed reactions that show convex Arrhenius plots, which are very rare, and points out that Tolman's interpretation of the activation energy places a fundamental model-independent constraint on any detailed explanation of these reactions. The analysis presented here shows that in such systems, the rate coefficient as a function of energy is not just increasing more slowly than expected, it is actually decreasing. This interpretation of the data provides a constraint on proposed microscopic models, i.e., it requires that any successful model of a reaction with a convex Arrhenius plot should be consistent with the microcanonical rate coefficient being a decreasing function of energy. The implications and limitations of this analysis to interpreting enzyme mechanisms are discussed. This model-independent conclusion has broad applicability to all fields of kinetics, and we also draw attention to an analogy with diffusion in metastable fluids and glasses. PMID:11158559

Markova, Gergana; Folger, Robert

2012-01-01

Drawing on the labeling perspective of deviance, we investigate employee reactions to coworkers perceived as deviants. We look at two positive effects for employees in the presence of a deviant coworker. First, in comparison to a deviant individual, other employees can draw more positive conclusions about themselves; and second, a deviant can be informative about organizational norms, thereby improving employee role clarity. We also examine individual and situational moderators. For the purpose of the study, we developed a measure of the presence of a deviant. The hypothesized relationships were tested in two large samples using multiple regression analyses. The results revealed that in the presence of a deviant coworker, employees reported enhanced self-evaluation. The presence of a deviant coworker was associated with better role clarity only for employees with more interdependent jobs. We also discuss practical implications of the findings and future research directions.

Zone of Proximal Development (ZPD) as an Emergent System: A Dynamic Systems Theory Perspective.

PubMed

Karimi-Aghdam, Saeed

2017-03-01

This paper sets out to present a novel construal of one of the notions of Vygotskian cultural-historical theory viz., zone of proximal development (ZPD) drawing upon dynamic systems theory. The principal thesis maintains that ZDP is an emergent and dynamic system which is engendered by a dialectical concatenation of psychogenesic and sociogenesic facets of human development over time. It is reasoned that Vygotskian cultural-historical theory of human development, by invoking dialectical logic, has transcended Cartesian substance dualism and in turn has proffered a monistic and process-anchored ontology for emerging becoming of human consciousness. Likewise, it is contended that dynamic systems theory, having assumed fluent flux of reality with a capital R as its ontological axiom, entails a consilience of cognitive and contextual conceptual schemes to describe, explain, and optimize human development. The paper concludes by drawing some interpretive conclusions in regard to ZPD from dynamic systems theory perspective.

The role of the residential neighborhood in linking youths' family poverty trajectory to decreased feelings of safety at school.

Although disadvantaged youth are more likely to be victimized at school, victimization only partly explains their decreased feelings of safety at school. We applied a socioecological approach to test the hypotheses that the experience of poverty is associated with decreased feelings of safety at school, and that residential neighborhood features partly mediate the relationship between poverty and feeling less safe at school. This study draws on the Québec Longitudinal Study of Child Development (QLSCD) which began in 1998 with a representative population-based cohort of 2,120 5-month old infants (49.1% female) and their primary caregiver. The study also includes measures of ego-centred residential neighborhood exposures (based on a 500 m circular buffer zone surrounding the family's residential postal code) derived from a spatial data infrastructure. We used latent growth modeling to estimate youth's family poverty trajectory from age 5 months to 13 years, and structural equation modeling to test our hypotheses. The results suggest that youth experiencing chronic and later-childhood poverty felt less safe at school in part because they lived in neighborhoods that their parents described as being disorderly (e.g., demarked by the presence of garbage, drug use and groups of trouble-makers). These neighborhoods also tended to have less greenery (e.g., trees, parks) and more lone-parent households. Neighborhood features did not help explain the relationship between early-childhood poverty and feeling less safe at school. The findings suggest that targeting residential neighborhood features such as greenery and disorder could improve youth's felt safety at school, particularly for those experiencing chronic and later-childhood poverty.

Making home visits: Creativity and the embodied practices of home visiting in social work and child protection

PubMed Central

2016-01-01

Although the home is the most common place where social work goes on, research has largely ignored the home visit. Drawing on a participant observation study of child protection work, this article reveals the complex hidden practices of social work on home visits. It is argued that home visits do not simply involve an extension of the social work organisation, policies and procedures into the domestic domain but the home constitutes a distinct sphere of practice and experience in its own right. Home visiting is shown to be a deeply embodied practice in which all the senses and emotions come into play and movement is central. Through the use of creativity, craft and improvisation practitioners ‘make’ home visits by skilfully enacting a series of transitions from the office to the doorstep, and into the house, where complex interactions with service users and their domestic space and other objects occur. Looking around houses and working with children alone in their bedrooms were common. Drawing upon sensory and mobile methods and a material culture studies approach, the article shows how effective practice was sometimes blocked and also how the home was skilfully negotiated, moved around and creatively used by social workers to ensure parents were engaged with and children seen, held and kept safe.

Ecological and socio-demographic differences in maternal care services in Nepal

PubMed Central

Singh, Rajvir

2015-01-01

Background. Nepal is set to achieve MDG-5 goals by end of 2015. However, maternal health parameters will remain way below those of developed countries. This study was conducted to assess the factors contributing to utilization of ANC and safe delivery services with the aim of furthering overall maternal health parameters in Nepal. Material and Methods. Using survey data from the Nepal Demographic and Health Survey 2011, socio-economic and demographic factors associated with the utilization of ANC and safe delivery services among women aged 15–49 years who gave births during the last three years preceding the survey are examined. Data was segregated into three ecological zones: Mountain, Hill and Terai zones for univariate analyses. Data from all three zones was then pooled for univariate and multivariate logistic regression analyses of Antenatal Care and Safe Delivery services in Nepal. Results and Conclusion. The analyses show that rural place of residence is at a disadvantage in receiving ANC (OR, 0.8; 95% CI [0.7–0.9]) and ensuring safe delivery (OR, 0.6; 95% CI [0.5–0.7]). Woman’s education, husband’s education and wealth quintile are significant factors in ensuring ANC and safe delivery services. Further, the analyses show that Budh/Muslim/Kirat/Christians are at a significant disadvantage in ensuring safe delivery (OR, 0.8; 95% CI [0.7–0.9]) as compared with Hindus. Though ecological zones lost their significance in receiving ANC, women in the Terai region are at a significant advantage in ensuring safe delivery (OR, 1.7; 95% CI [1.2–2.1]). Recommendation. Segregated targets should be set for the different ecological zones for further improvement in maternal mortality rates in Nepal. PMID:26355429

Antibiotics or probiotics as preventive measures against ventilator-associated pneumonia: a literature review

PubMed Central

2011-01-01

Introduction Mechanically ventilated critically ill patients frequently develop ventilator-associated pneumonia (VAP), a life-threatening complication. Proposed preventive measures against VAP include, but are not restricted to, selective decontamination of the digestive tract (SDD), selective oropharyngeal decontamination (SOD) and the use of probiotics. Probiotics are live bacteria that could have beneficial effects on the host by altering gastrointestinal flora. Similar to SDD and SOD, a prescription of probiotics aims at the prevention of secondary colonization of the upper and/or lower digestive tract. Methods We performed a literature review to describe the differences and similarities between SDD/SOD and probiotic preventive strategies, focusing on (a) efficacy, (b) risks, and (c) the routing of these strategies. Results Reductions in the incidence of VAP have been achieved with SDD and SOD. Two large randomized controlled trials even showed reduced mortality with these preventive strategies. Randomized controlled trials of probiotic strategies also showed a reduction of the incidence of VAP, but trials were too small to draw firm conclusions. Preventive strategies with antibiotics and probiotics may be limited due to the risk of emerging resistance to the locally applied antibiotics and the risk of probiotic-related infections, respectively. The majority of trials of SDD and SOD did not exhaustively address the issue of emerging resistance. Likewise, trials of probiotic strategies did not adequately address the risk of colonization with probiotics and probiotic-related infection. In studies of SDD and SOD the preventive strategy aimed at decontamination of the oral cavity, throat, stomach and intestines, and the oral cavity and throat, respectively. In the vast majority of studies of probiotic therapy the preventive strategy aimed at decontamination of the stomach and intestines. Conclusions Prophylactic use of antibiotics in critically ill patients is effective in reducing the incidence of VAP. Probiotic strategies deserve consideration in future well-powered trials. Future studies are needed to determine if preventive antibiotic and probiotic strategies are safe with regard to development of antibiotic resistance and probiotic infections. It should be determined whether the efficacy of probiotics improves when these agents are provided to the mouth and the intestines simultaneously. PMID:21232110

The Royal College of Anaesthetists 6th National Audit Project examined Grade 3-5 perioperative anaphylaxis for one year in the UK. To describe the causes and investigation of anaphylaxis in the NAP6 cohort, in relation to published guidance and previous baseline survey results. We used a secure registry to gather details of Grade 3-5 perioperative anaphylaxis. Anonymous reports were aggregated for analysis and reviewed in detail. Panel consensus diagnosis, reaction grade, review of investigations and clinic assessment are reported and compared to the prior NAP6 baseline clinic survey. 266 cases met inclusion criteria between November 2015 and 2016, detailing reactions and investigations. 192/266 (72%) had anaphylaxis with a trigger identified, of which 140/192(75%) met NAP6 criteria for IgE-mediated allergic anaphylaxis, 13% lacking evidence of positive IgE tests were labelled "non-allergic anaphylaxis". 3% were non-IgE mediated anaphylaxis. Adherence to guidance was similar to the baseline survey for waiting time for clinic assessment. However, lack of testing for chlorhexidine and latex, non-harmonised testing practices and poor coverage of all possible culprits was confirmed. Challenge testing may be under-used and many have unacceptably delayed assessments, even in urgent cases. Communication or information provision for patients was insufficient, especially for avoidance advice and communication of test results. Insufficient detail regarding skin test methods was available to draw conclusions regarding techniques. Current clinical assessment in the UK is effective but harmonisation of approach to testing, access to services and MHRA reporting is needed. Expert anaesthetist involvement should increase to optimise diagnostic yield and advice for future anaesthesia. Dynamic tryptase evaluation improves detection of tryptase release where peak tryptase is <14mcg/L and should be adopted. Standardised clinic reports containing appropriate details of tests, conclusions, avoidance, cross-reactivity and suitable alternatives are required to ensure effective, safe future management options.

Analysis of Children's Perception of Triatomine Vectors of Chagas Disease through Drawings: Opportunities for Targeted Health Education

PubMed Central

Yevstigneyeva, Violetta; Camara-Mejia, Javier; Dumonteil, Eric

2014-01-01

Background Chagas disease is a tropical parasitic disease affecting about 10 million people, mostly in the Americas, and transmitted mainly by triatomine bugs. Insect vector control with indoor residual insecticides and the promotion of housing improvement is the main control intervention. The success of such interventions relies on their acceptance and appropriation by communities, which depends on their knowledge and perceptions of both the disease and the vector. In this study, we investigated school-aged children's knowledge and perception on triatomine vectors and Chagas disease to further understand how communities view this vector and the disease in Yucatan, Mexico. Methodology/Principal findings We performed an analysis of children's drawings on the theme of triatomines and their house in several rural villages, to explore in an open-ended manner their views, understanding and misconceptions. A total of 261 drawings were collected from children ages 6–12 from four villages. We found that children are very familiar with triatomine vectors, and know very well many aspects of their biology and ecology, and in particular their blood-feeding habits. On the other hand, their drawings suggest that the role of triatomines as vectors of a chronic and severe cardiac disease is less understood, and the main perceived health threat appears limited to the bite itself, as previously observed in adults. Conclusions/Significance These results have important implications for the specific design of future education materials and campaigns, and for the promotion of the inclusion of children in raising Chagas disease awareness in these endemic communities.

"Neuroreductionism" is the tendency to reduce complex mental phenomena to brain states, confusing correlation for physical causation. In this paper, we illustrate the dangers of this popular neuro-fallacy, by looking at an example drawn from the media: a story about "hypoactive sexual desire disorder" in women. We discuss the role of folk dualism in perpetuating such a confusion, and draw some conclusions about the role of "brain scans" in our understanding of romantic love.

The number of viruses isolated from fish has grown in the last few years as a reflection of the increasing interest in fish diseases, particularly those occurring in aquaculture facilities. Of all the described viruses, only a few are considered to be of serious concern and economic importance; they are described in this review, drawing special attention to the four families of viruses (Birnaviridae, Rhabdoviridae, Iridoviridae and Reoviridae) that have been reported in Spanish aquaculture. Infectious pancreatic necrosis virus, a member of the first family, is the most spread virus with a prevalence of 39%. Viral diseases are untreatable and because effective and safe vaccines for fish are not yet commercially available, a great care needs to be exercised when moving fish or eggs from one site or country to another. Some fish health control regulations have been legislated in Europe and USA.

Space Shuttle Drawing

The Apollo program demonstrated that men could travel into space, perform useful tasks there, and return safely to Earth. But space had to be more accessible. This led to the development of the Space Shuttle. The Shuttle's major components are the orbiter spacecraft; the three main engines, with a combined thrust of more than 1.2 million pounds; the huge external tank (ET) that feeds the liquid hydrogen fuel and liquid oxygen oxidizer to the three main engines; and the two solid rocket boosters (SRBs), with their combined thrust of some 5.8 million pounds, that provide most of the power for the first two minutes of flight. Crucially involved with the Space Shuttle program virtually from its inception, the Marshall Space Flight Center (MSFC) played a leading role in the design, development, testing, and fabrication of many major Shuttle propulsion components.

This article presents an innovative project to develop and trial a prototype product called 'trove' to start to address challenges identified regarding current practice of life story work with children who are looked after and adopted. trove is a digitally enhanced memory box that utilises raspberry pi (a small single board computer) and radio-frequency identification (RFID) technologies to enable children to record their memories and to attach these to their precious objects using an electronic tag: providing a safe 'container' for their mementoes and memories. Located in theories of narrative identity and object attachment and drawing on Brodinsky's concept of communicative openness, we describe the children's engagements in the design and report the results of a small trial of 10 troves with adopted children in England.

Healthcare professionals work in emotionally charged settings; yet, little is known about the role of emotion in ensuring safe patient care. This article presents current knowledge in this field, drawing upon psychological approaches and evidence from clinical settings. We explore the emotions that health professionals experience in relation to making a medical error and describe the impact on healthcare professionals and on their professional and patient relationships. We also explore how positive and negative emotions can contribute to clinical decision making and affect responses to clinical situations. Evidence to date suggests that emotion plays an integral role in patient safety. Implications for training, practice and research are discussed in addition to strategies to facilitate health services to understand and respond to the influence of emotion in clinical practice. © The Royal Society of Medicine.

Over one half of the patients diagnosed with advanced lung cancer experience anorexia. In addition to its high incidence, cancer-induced anorexia promotes the development of the anorexia-cachexia syndrome, which is related to poor clinical outcomes. Recently, drugs derived from cannabinoids, such as Nabilone, have been recognized for their appetite improvement properties; however, clinical trials to support their use in cancer patients are necessary. This is a randomized, double-blind, placebo-controlled clinical trial to assess the effect of Nabilone vs. placebo on the appetite, nutritional status, and quality of life in patients diagnosed with advanced Non-small cell lung cancer (NSCLC) (NCT02802540). A total of 65 patients from the outpatient clinic at the National Institute of Cancer (INCan) were assessed for eligibility and 47 were randomized to receive Nabilone (0.5 mg/2 weeks followed by 1.0 mg/6 weeks) or placebo. After 8 weeks of treatment, patients who received Nabilone increased their caloric intake (342-kcal) and had a significantly higher intake of carbohydrates (64 g) compared to patients receiving placebo (p = 0.040). Quality of life also showed significant improvements in patients in the experimental arm of the trial, particularly in role functioning (p = 0.030), emotional functioning (p = 0.018), social functioning (p = 0.036), pain (p = 0.06), and insomnia (p = 0.020). No significant change in these scales was seen in the control group. Nabilone is an adequate and safe therapeutic option to aid in the treatment of patients diagnosed with anorexia. Larger trials are necessary in order to draw robust conclusions in regard to its efficacy in lung cancer patients.

The Lidköping Accident Prevention Programme--a community approach to preventing childhood injuries in Sweden.

In Sweden about 100 children 0-14 years die from accidental injuries every year, roughly 40 girls and 60 boys. To reduce this burden the Safe Community concept was developed in Falköping, Sweden in 1975. Several years later a second programme was initiated in Lidköping. The objectives of this paper are to describe the programme in Lidköping and to relate it to changes in injury occurrence. The Lidköping Accident Prevention Programme (LAPP) was compared with four bordering municipalities and to the whole of Skaraborg County. The programme included five elements: surveillance, provision of information, training, supervision, and environmental improvements. Process evaluation was based mainly on notes and reports made by the health planners, combined with newspaper clippings and interviews with key people. Outcome evaluation was based on information from the hospital discharge registry. In Lidköping there was an on average annual decrease in injuries leading to hospital admissions from 1983 to 1991 of 2.4% for boys and 2.1% for girls compared with a smaller decline in one comparison area and an increase in the other. Because the yearly injury numbers are small there is a great variation from year to year. However, comparisons over the nine year study period with the four border municipalities and the whole of Skaraborg County strengthen the impression that the programme has had a positive effect. The findings support the proposition that the decrease in the incidence of childhood injuries after 1984 could be attributed to the intervention of the LAPP. Nevertheless, several difficulties in drawing firm conclusions from community based studies are acknowledged and discussed.
