2017-01-01

Vitamin D (Vit D) deficiency is a common disorder in diabetic patients and may be a risk factor for ischemic heart disease and exacerbation of diabetic nephropathy(DN). The aim of this study was to evaluate the effect of Vit D3 therapy on protein uriain type 2 diabetic patients with deficient or insufficient serum Vit D. In a double blind clinical trial, 60 type 2 diabetic patients with proteinuria greater than 150 mg/day who had Vit D deficiency or insufficiency were randomly enrolled in two equal groups. Pearl of Vit D as 50 000 IU/week and placebo (1 tablet per week) were prescribed in patients of case and control groups respectively for 8 weeks. At the beginning and 2 months later, 24 hours urine protein was checked in all patients. There is no difference between serums Vit D level in case and control group at the beginning of the study, however at the end of the study serum Vit D level was significantly higher in the case group. There is no difference in proteinuria between case and control group at the beginning and the end of the study, while a significant difference between the changes of proteinuria before and after the study was seen in two groups ( P = 0.028). Vit D deficiency may exacerbate protein uric and DN, hence correction of Vit D deficiency may decrease proteinuria in diabetic patients with nephropathy.

[Bacterial vaginosis and preterm delivery risk].

PubMed

Milewicz, Tomasz; Hejnar, Janusz; Jach, Robert; Jaworowski, Andrzej P; Piskorz, Tomasz; Gach, Andrzej; Krzysiek, Józef

2010-01-01

The aim of the study was to evaluate the impact of early, second trimester bacterial vaginosis [BV] on the number of threatened preterm deliveries. Group A consisted of 52 pregnant women in whom BV was diagnosed in the beginning of the 2nd trimester of pregnancy. Group A patients were treated with a 10 day course of metronidazole 0.5 g vaginally daily. Group B consisted of 122 pregnant women without BV. The number of cases with threatened preterm delivery was prospectively assessed in both groups. There were 28 cases of threatened preterm delivery in group A (53.8%) and 6 similar cases in group B (4.9%) (p < 0.05--Chi square test d.f.1). All cases (n = 20) of BV at the time of hospitalization due to threatened preterm delivery occurred in group A. The cases of threatened preterm delivery occurred significantly more frequently in pregnant patients who had the BV diagnosed in the beginning of the 2nd trimester. This may suggest the link between BV and the occurrence of threatened preterm deliveries.

Mentioning race at the beginning of clinical case presentations: a survey of US medical schools.

PubMed

Nawaz, Hamayun; Brett, Allan S

2009-02-01

Medical students and doctors in the USA frequently mention the patient's race at the beginning of oral or written clinical case presentations. However, this practice is controversial. We aimed to determine whether US medical schools explicitly teach students to mention race at the beginning of case presentations, and to collect additional information on the schools' perspectives on this practice. An Internet-based questionnaire was submitted to directors of courses on history taking and physical examination at all US medical schools. The response rate was 85%. Students are taught to mention race routinely at 11% of schools and selectively at 63% of schools; this practice is discouraged at 9% of schools and not addressed at 18% of schools. Most respondents noted that resident doctors at their institutions routinely mention race at the beginning of case presentations. Even at schools in which mentioning race is discouraged or not addressed, students tend to include race during their clinical rotations. Respondents were divided on whether a standardised approach to inclusion of race should exist at US schools. Teaching about inclusion or exclusion of race in the opening statement of clinical case presentations varies across US medical schools. This variation presents an opportunity for medical educators to discuss tensions between stereotyping and cultural competence in medical education.

CASE STUDY RESEARCH: THE VIEW FROM COMPLEXITY SCIENCE

PubMed Central

Anderson, Ruth; Crabtree, Benjamin F.; Steele, David J.; McDaniel, Reuben R.

2005-01-01

Many wonder why there has been so little change in care quality, despite substantial quality improvement efforts. Questioning why current approaches are not making true changes draws attention to the organization as a source of answers. We bring together the case study method and complexity science to suggest new ways to study health care organizations. The case study provides a method for studying systems. Complexity theory suggests that keys to understanding the system are contained in patterns of relationships and interactions among the system’s agents. We propose some of the “objects” of study that are implicated by complexity theory and discuss how studying these using case methods may provide useful maps of the system. We offer complexity theory, partnered with case study method, as a place to begin the daunting task of studying a system as an integrated whole. PMID:15802542

Inquiry practice and identity of beginning secondary science teachers in the online and offline learning community: A longitudinal mixed methods study

NASA Astrophysics Data System (ADS)

Bang, Eunjin

This two-year study explored changes in practices and the emerging identities of beginning secondary science teachers who participated in an online science specific mentoring program. Fourteen beginning secondary science teachers and six experienced secondary science teachers were selected for the study. As a mixed methods study, data were gathered quantitatively and qualitatively. A hierarchical linear modeling was used in order to depict the changes in inquiry-based science practices as a result of content-focused online mentoring program. Qualitative data were collected via monthly semi-structured interviews, pre, post, and follow-up yearly semi-structured interviews, and finally online written dialogues of beginning secondary science teachers and their e-mentors. A mixed method was used that utilized the results of quantitative data, Items for Inquiry-Based Practice (IBP) scores, helped for selecting cases for qualitative analysis. Results indicated that there were no significant differences in IBP scores among the fourteen beginning secondary science teachers; however, three groups were detected: increasing use, no change, and decreasing use in inquiry-based practices. Porsha, who made increasing use, showed four emerging identities throughout two years: watchful-imitator, seeker, collaborator, and junior-leader. Nora, who made no change, showed only two emerging identities: imitator and seeker. Netty, who made decreasing use, showed also two emerging identities: lonely-follower and feeder. Different identities detected in online dialogue, namely Porsha as a whistleblower, Nora as a watchful-imitator, and Netty as a watchful-feeder. The corresponding responses of three beginning secondary science teachers' e-mentors were defender, provider, listener, pusher and umpire. This study provides not only an in-depth picture of the contemporary science education community of practice but also suggest a roadmap to design an effective induction program.

fmCASES National Examination as a Pretest in a Family Medicine Clerkship.

Nguyen, Dana; Servey, Jessica T; Scott, LaTraia S

2018-02-01

Pretests have been shown to contribute to improved performance on standardized tests by serving to facilitate development of individualized study plans. fmCASES is an existing validated examination used widely in family medicine clerkships throughout the country. Our study aimed to determine if implementation of the fmCASES National Examination as a pretest decreased overall failure rates on the end-of-clerkship National Board of Medical Examiners (NBME) subject examination, and to assess if fmCASES pretest scores correlate with student NBME scores. One hundred seventy-one and 160 clerkship medical students in different class years at a single institution served as the control and intervention groups, respectively. The intervention group took the fmCASES National Examination as a pretest at the beginning of the clerkship and received educational prescriptions based on the results. Chi-square analysis, Pearson correlation, and receiver operating curve analysis were used to evaluate the effectiveness and correlations for the intervention. Students completing an fmCASES National Examination as a pretest failed the end-of-clerkship NBME exam at significantly lower rates than those students not taking the pretest. The overall failure rate for the intervention group was 8.1% compared to 17.5% for the control group (P=0.01). Higher pretest scores correlated with higher NBME examination scores (r=0.55, P<0.001). fmCASES National Examination is helpful as a formative assessment tool for students beginning their family medicine clerkship. This tool introduces students to course learning objectives, assists them in identifying content areas most in need of study, and can be used to help students design individualized study plans.

The role of socioeconomic status in longitudinal trends of cholera in Matlab, Bangladesh, 1993-2007.

Root, Elisabeth Dowling; Rodd, Joshua; Yunus, Mohammad; Emch, Michael

2013-01-01

There has been little evidence of a decline in the global burden of cholera in recent years as the number of cholera cases reported to WHO continues to rise. Cholera remains a global threat to public health and a key indicator of lack of socioeconomic development. Overall socioeconomic development is the ultimate solution for control of cholera as evidenced in developed countries. However, most research has focused on cross-county comparisons so that the role of individual- or small area-level socioeconomic status (SES) in cholera dynamics has not been carefully studied. Reported cases of cholera in Matlab, Bangladesh have fluctuated greatly over time and epidemic outbreaks of cholera continue, most recently with the introduction of a new serotype into the region. The wealth of longitudinal data on the population of Matlab provides a unique opportunity to explore the impact of socioeconomic status and other demographic characteristics on the long-term temporal dynamics of cholera in the region. In this population-based study we examine which factors impact the initial number of cholera cases in a bari at the beginning of the 0139 epidemic and the factors impacting the number of cases over time. Cholera data were derived from the ICDDR,B health records and linked to socioeconomic and geographic data collected as part of the Matlab Health and Demographic Surveillance System. Longitudinal zero-inflated Poisson (ZIP) multilevel regression models are used to examine the impact of environmental and socio-demographic factors on cholera counts across baris. Results indicate that baris with a high socioeconomic status had lower initial rates of cholera at the beginning of the 0139 epidemic (γ(01) = -0.147, p = 0.041) and a higher probability of reporting no cholera cases (α(01) = 0.156, p = 0.061). Populations in baris characterized by low SES are more likely to experience higher cholera morbidity at the beginning of an epidemic than populations in high SES baris.

Tuberculosis (TB) is a major issue in prisons of low and middle income countries where TB incidence rates are much higher in prison populations as compared with the general population. In the Rio de Janeiro (RJ) State prison system, the TB control program is limited to passive case-finding and supervised short duration treatment. The aim of this study was to measure the impact of X-ray screening at entry associated with systematic screening on the prevalence and incidence of active TB. We followed up for 2 years a RJ State prison for adult males (1429 inmates at the beginning of the study) and performed, in addition to passive case-finding, 1) two "cross-sectional" X-ray systematic screenings: the first at the beginning of the study period and the second 13 months later; 2) X-ray screening of inmates entering the prison during the 2 year study period. Bacteriological examinations were performed in inmates presenting any pulmonary, pleural or mediastinal X-ray abnormality or spontaneously attending the prison clinic for symptoms suggestive of TB. Overall, 4326 X-rays were performed and 246 TB cases were identified. Prevalence among entering inmates remained similar during 1st and the 2nd year of the study: 2.8% (21/754) and 2.9% (28/954) respectively, whereas prevalence decreased from 6.0% (83/1374) to 2.8% (35/1244) between 1st and 2nd systematic screenings (p < 0.0001). Incidence rates of cases identified by passive case-finding decreased from 42 to 19 per 1000 person-years between the 1st and the 2nd year (p < 0.0001). Cases identified by screenings were less likely to be bacteriologically confirmed as compared with cases identified by passive-case finding. The strategy investigated, which seems highly effective, should be considered in highly endemic confined settings such as prisons.

Astronomy and religion (1780-1915). Four case studies involving ideas of extraterrestrial life

NASA Astrophysics Data System (ADS)

Crowe, Michael J.

The present essay discusses four examples of interactions, two from the eighteenth century and two from the nineteenth. All four cases concern the relations between religion and the astronomical claim that intelligent beings exist elsewhere in space. In each of these four cases religious claims influenced astronomy. Cases 3 and 4 share a feature not usually encountered in studies on the interactions of astronomy and religion in that they are instances where not just theistic belief but in fact core doctrines of a specific religion, Christianity, influenced astronomy. I begin by surveying the interactions between religion and the idea of extraterrestrial intelligent life in the early modern period.

Temperature dynamics of soft tissues during diode laser cutting by different types of fiber opto-thermal converters

2017-03-01

The results of in vitro study of the soft tissue temperature dynamics during 980 nm diode laser cutting by different types (CLEAR, FILM, VOLUMETRIC) of fiber opto-thermal converters (FOTC) are presented. It was found that the use of CLEAR fiber end (tip) at the laser power below 8.5 W doesn't lead to the soft tissue (chicken meat) destruction. The chicken meat destruction (cutting) begins when irradiated by 8.5 W laser radiation for approximately 9.0 s. At the power of 9.0 W this time decreases up to 7.0 s, at 9.5 W - to 6.0 s, at 10.0 W - to 3.5 s. The moment of soft tissue cutting start correlates with the moment of black layer (absorber) formation at the fiber end and appearance of visually identifiable laser cut walls on the photos; the temperature in this case rapidly increases up to 850 °C. It was determined that the FILM FOTC begins to cut the soft tissue immediately after exposure of laser radiation with power of 4.0 W, the temperature in this case reaches 900 °C. It was determined that the VOLUMETRIC FOTC begins to cut the tissue immediately after exposure at the power of 1.0 W, the temperature in this case reaches 600 °C. VOLUMETRIC FOTC can produce more effective cuts of the soft tissue at the laser power of 4.0 W, in this case, the temperature is above 1200 °C.

Studies about head trauma are experimental or have a clinical or prognosis purpose. In this study, we used samples from human autopsies to answer common medical-legal questions.We studied 21 problem cases and 4 controls. Samples were obtained directly from the injured area, fixed in 10% formalin during 24 hours and then preserved in 70% ethanol. This procedure optimizes the immunohistochemical technique.The neurofilament antibody shows beaded axons since the first moment; over time, they increase their density and diameter as survival time also increases. These changes begin in the gray matter, 2 hours after trauma can be seen around vessels and in hemorrhagic areas. At 24 hours, beaded axons appear in the white mater, which finally loses its structure and cellular density.On the other hand, the β-amyloid precursor protein marker begins to be weakly seen 2 hours after injury. At 24 hours, a diffuse pattern can appear, suggesting primary traumatic injury. The marker reading keeps increasing until day 26, when a "Z" pattern appears in the white matter, suggesting secondary hypoxic injury.All these chronologic changes could be useful to approach the date of trauma. They let us to distinguish between long surviving cases from those whose death was immediate (within the first 30 minutes).

Lung cancer is the leading cause of cancer mortality worldwide. Tobacco smoking is its primary cause, and yet the precise molecular alterations induced by smoking in lung tissue that lead to lung cancer and impact survival have remained obscure. A new framework of research is needed to address the challenges offered by this complex disease. We designed a large population-based case-control study that combines a traditional molecular epidemiology design with a more integrative approach to investigate the dynamic process that begins with smoking initiation, proceeds through dependency/smoking persistence, continues with lung cancer development and ends with progression to disseminated disease or response to therapy and survival. The study allows the integration of data from multiple sources in the same subjects (risk factors, germline variation, genomic alterations in tumors, and clinical endpoints) to tackle the disease etiology from different angles. Before beginning the study, we conducted a phone survey and pilot investigations to identify the best approach to ensure an acceptable participation in the study from cases and controls. Between 2002 and 2005, we enrolled 2101 incident primary lung cancer cases and 2120 population controls, with 86.6% and 72.4% participation rate, respectively, from a catchment area including 216 municipalities in the Lombardy region of Italy. Lung cancer cases were enrolled in 13 hospitals and population controls were randomly sampled from the area to match the cases by age, gender and residence. Detailed epidemiological information and biospecimens were collected from each participant, and clinical data and tissue specimens from the cases. Collection of follow-up data on treatment and survival is ongoing. EAGLE is a new population-based case-control study that explores the full spectrum of lung cancer etiology, from smoking addiction to lung cancer outcome, through examination of epidemiological, molecular, and clinical data. We have provided a detailed description of the study design, field activities, management, and opportunities for research following this integrative approach, which allows a sharper and more comprehensive vision of the complex nature of this disease. The study is poised to accelerate the emergence of new preventive and therapeutic strategies with potentially enormous impact on public health.

The purpose of the study was to evaluate medical, social, and economic effectiveness of treatment of day-case patients with peptic ulcer (PU). The subjects of the study were 60 day-case patients with duodenal ulcer aged 18 to 60, who underwent clinical and instrumental examination including esophagogastroduodenoscopy with biopsy and Helicobacter pylori (HP) detection. The patients received 7-day eradication therapy, which included omeprazol in a dose of 20 mg twice a day, clarithromycin--500 mg twice a day, and metronidazole--500 mg twice a day. There was a control group, which included 60 inpatients treated in Gastroenterology Division of the hospital. The use of the three-component medication in the day-case patients and the inpatients led to disappearance of pain syndrome 7.4 +/- 0.3 and 8.6 +/- 0.2 days after the beginning of the treatment, respectively; dyspepsia disappeared in the day-case patients and the inpatients 7.6 +/- 0.2 and 8.8 +/- 0.3 days after the beginning of the treatment, respectively. HP eradication was effective in 86.7% of the day-case patients, and in 88.3% of the inpatients. The course of the disease was recurrence-free during two years in 80% of the day-case patients, and in 76.4% of the inpatients; the cost of the treatment was 2.1 times higher in the group of inpatients. The results show that high effectiveness of the three-component medication, judging by the results of HP eradication, terms of disappearance of pain syndrome and ulcer healing, allows recommending this regimen for wide clinical application in day-case patients with PU.

A case study on modeling and independent practice cycles in teaching beginning science inquiry

NASA Astrophysics Data System (ADS)

Sadeghpour-Kramer, Margaret Ann Plattenberger

With increasing pressure to produce high standardized test scores, school systems will be looking for the surest ways to increase scores. Decision makers uninformed about the value of inquiry science may recommend more direct teaching methods and curricula in the hope that students will more quickly accumulate factual information for high test scores. This researcher and other proponents of inquiry science suggest that the best preparation for any test is the ability to use all available information and problem solving skills to think through to a solution. This study proposes to test the theory that inquiry problem solving skills need to be modeled and practiced in increasingly independent situations to be learned. Students tend to copy what they have been led to believe is correct, and to avoid continued copying, their skills must be applied in new situations requiring independent practice and improvement. This study follows ten sixth grade students, selected for maximum variation, as they participate in a series of five cycles of modeling and practicing inquiry science investigations as part of an ongoing unit on water quality. The cycles were designed to make the students increasingly independent in their use of inquiry. The results showed that all ten students made significant progress from copying teacher modeling in investigation #1 towards independent inquiry, with nine of the ten achieving acceptable to good beginning independent inquiry in investigation #5. Each case was analyzed independently using such case study methodology as pattern matching, case study protocols, and theoretical propositions. Constant comparison and other case study methods were used in a cross-case analysis. Eight cases confirmed a matching set of propositions and the hypothesis, in literal replication, and the other two cases confirmed a set of propositions and the hypothesis through theoretical replication. The study suggests to educators that repeated cycles of modeling and increasingly independent practice serve three purposes; first to develop independent inquiry skills by providing multiple opportunities with intermittent modeling, second to repeat the modeling initially in very similar situations and then encourage transfer to new situations, and third to provide repeated modeling for those students who do not grasp the concepts as quickly as do their classmates.

Problem-based learning within endocrine physiology lectures.

PubMed

Walters, M R

2001-12-01

Methods were needed to improve the interest of medical students in the 10-lecture Endocrine Physiology block at the end of the second semester of study. Other incentives for improvement included the possibility of attracting students into endocrine research electives and the pressure to improve teaching approaches that results from the high tuition they pay. The principal approach adopted was that of whole class problem-based learning sessions (PBLS) in which the lecture period begins with a brief overview of one to three simplified cases, followed by the usual didactic lecture. At the end of the lecture, each PBL case is read in detail, with several questions posed to the students. Their answers are then used to reinforce concepts from the lecture material. This method can also provide some continuity between lectures, either by using a case in several lectures to illustrate different points, or by posing a question at the beginning of class that illustrates a point from the prior lecture. The outcome of this approach has been very successful: student evaluations of the lecture block and their attendance have significantly improved.

Method of radiotherapy, dose, clinical symptoms, peripheral blood findings, and results of serum biochemical examination for nine infantile patients are discussed. Nine cases were composed of three cases of embryonal cell carcinoma, two of Wilm's tumor, and each one case of bone metastasis of neuroblastoma, histocytosis X, lymphosarcoma, and hepatoblastoma. High-voltsge roentgen therapy of 100 KVP was carried out in two cases, and Linac x-ray therapy In eight cases. Dose ranged from 1000 to 4000 R and days of irradiation ranged from 5 to 54 days. rt was dffficult to distinguish between radiotoxemia and side effect due to irradiation becausemore » there were many relatively severe cases although there was not any case that needed discontinuation of rodiotherapy. After irradiation, fatigue was recognized in four cases, anorexia in four cases, nausea and vomiting in three cases, and weight loss in two cases, but an attack of fever, diarrhea, and proteinuria were not recognized in any case. Peripheral blood finding and serum biochemical examination were carried out before radiotherapy, in two weeks after beginning of radiotherapy and in two weeks after finishlng of radiotherapy. The greater port of cases showed a slight decrease of leukocyte count. Although there was a case in which neutrophils out of leukocyte tended to increase after finishing of therapy, lymphocyte count had a tendency to decrease since beginning of therapy and its recovery was not recognized for a short time after finishing of irradiatlon. With respect to serum biochemical examination, only a little elevation of GOT and GPT was recognized in one case of bone metastasis of neuroblastoma treated with high voltage roentgen therspy in two weeks after beginning of irradiation. Two cases of Wilm's tumor showed eosinophilia in response to enforcement of irradiation. Diagnosis, chief complaints, past medical history, present illness, present condition, and physical examination results on admission of each case were also added. (JA)« less

Developing a workable teacher identity: Building and negotiating identity within a professional network

NASA Astrophysics Data System (ADS)

Rostock, Roseanne

The challenge of attracting and retaining the next generation of teachers who are skilled and committed to meeting the growing demands of the profession is of increasing concern to researchers and policy makers, particularly since 45--50% of beginning teachers leave the profession within five years (Ingersoll & Smith, 2003). Reasons for such attrition include compensation, status and working conditions; however, there is growing evidence that a critical factor in new teacher retention hinges on teachers' ability to accomplish the difficult task of forming a workable professional identity in the midst of competing discourses about teaching (Alsup, 2006; Britzman, 2003). There is little research on professional identity development among those beginning teachers at highest risk for attrition (secondary math and science teachers, and those with strong academic backgrounds). This study explores the professional identity development of early-career math and science teachers who are part of the Knowles Science Teaching Foundation's (KSTF) teaching fellowship program, an external support network that aims to address many of the issues leading to high attrition among this particular population of teachers. Using narrative research methods, I examine three case studies of beginning teachers, exploring how they construct professional identity in relation to various discourse communities and negotiate tensions across multiple discourses. The cases identify both dominant discourses and counter-discourses that the teachers draw upon for important identity development resources. They also demonstrate that the way a teacher manages tensions across competing discourses is important to how well one can negotiate a workable professional identity. In particular, they emphasize the importance of engaging in borderland discourses (Gee, 1996) as a way of taking agency in one's own identity development as well as in transforming one's discourse communities. These cases shed light on how these beginning teachers work to negotiate a workable professional identity that may sustain them in a teaching career. In addition, they help us understand how a support network like KSTF can serve as a resource for helping new teachers construct professional identities, therefore addressing some of the issues that may lead to attrition among this population of new teachers.

2017-01-01

Cholera is among the re-emerging diseases in Kenya. Beginning in December 2014, a persistent outbreak occurred involving 29 out of the 47 countries. Homa Bay County in Western Kenya was among the first counties to report cholera cases from January to April 2015. This case study is based on an outbreak investigation conducted by FELTP residents in Homa Bay County in February 2015. It simulates an outbreak investigation including laboratory confirmation, active case finding, descriptive epidemiology and implementation of control measures. This case study is designed for the training of basic level field epidemiology trainees or any other health care workers working in public health-related fields. It can be administered in 2-3 hours. Used as adjunct training material, the case study provides the trainees with competencies in investigating an outbreak in preparation for the actual real-life experience of such outbreaks.

The Role of Socioeconomic Status in Longitudinal Trends of Cholera in Matlab, Bangladesh, 1993–2007

PubMed Central

Root, Elisabeth Dowling; Rodd, Joshua; Yunus, Mohammad; Emch, Michael

2013-01-01

There has been little evidence of a decline in the global burden of cholera in recent years as the number of cholera cases reported to WHO continues to rise. Cholera remains a global threat to public health and a key indicator of lack of socioeconomic development. Overall socioeconomic development is the ultimate solution for control of cholera as evidenced in developed countries. However, most research has focused on cross-county comparisons so that the role of individual- or small area-level socioeconomic status (SES) in cholera dynamics has not been carefully studied. Reported cases of cholera in Matlab, Bangladesh have fluctuated greatly over time and epidemic outbreaks of cholera continue, most recently with the introduction of a new serotype into the region. The wealth of longitudinal data on the population of Matlab provides a unique opportunity to explore the impact of socioeconomic status and other demographic characteristics on the long-term temporal dynamics of cholera in the region. In this population-based study we examine which factors impact the initial number of cholera cases in a bari at the beginning of the 0139 epidemic and the factors impacting the number of cases over time. Cholera data were derived from the ICDDR,B health records and linked to socioeconomic and geographic data collected as part of the Matlab Health and Demographic Surveillance System. Longitudinal zero-inflated Poisson (ZIP) multilevel regression models are used to examine the impact of environmental and socio-demographic factors on cholera counts across baris. Results indicate that baris with a high socioeconomic status had lower initial rates of cholera at the beginning of the 0139 epidemic (γ01 = −0.147, p = 0.041) and a higher probability of reporting no cholera cases (α01 = 0.156, p = 0.061). Populations in baris characterized by low SES are more likely to experience higher cholera morbidity at the beginning of an epidemic than populations in high SES baris. PMID:23326618

Williams, George Sie; Naiene, Jeremias; Gayflor, Joseph; Malibiche, Theophil; Zoogley, Bentoe; Frank, Wimot G; Nayeri, Fariba

2015-08-01

As West Africa continues to suffer from a deadly Ebola epidemic, the national health sectors struggle to minimize the damages and stop the spread of disease. A cohort of inhabitants of a small village and an Ebola hot zone in Sinoe County of Liberia was followed on a day-by-day basis to search for new cases and to minimize the spread of Ebola to the other community members or to other regions. Technical, clinical, and humanistic aspects of the response are discussed in this report. Of the 22 confirmed Ebola cases in Sinoe County since the beginning of outbreak (June 16, 2014), 7 cases were inhabitants of Polay Town, a small village 5.5 miles east of Greenville, the Sinoe County capital. After the last wave of outbreak at the beginning of December, enhanced response activity provided essential coordination and mobilized the resources to stop the epidemic. Despite unprotected contacts in crowded houses, no new cases were detected among the contact families, or in the surrounding houses or communities. Strong national mobilization in a decentralized but harmonized system at the community level has been of great value in controlling the epidemic in Liberia. The major interventions include epidemiological surveillance, public information dissemination, effective communication, case management, and infection control. Copyright © 2015 The Authors.

Change in Psychotherapy: A Dialogical Analysis Single-Case Study of a Patient with Bulimia Nervosa

PubMed Central

Salvini, Alessandro; Faccio, Elena; Mininni, Giuseppe; Romaioli, Diego; Cipolletta, Sabrina; Castelnuovo, Gianluca

2012-01-01

Starting from the critical review of various motivational frameworks of change that have been applied to the study of eating disorders, the present paper provides an alternative conceptualization of the change in psychotherapy presenting a single-case study. We analyzed six psychotherapeutic conversations with a bulimic patient and found out narratives “for” and “against” change. We read them in terms of tension between dominance and exchange in I-positions, as described by Hermans. These results indicate that the dialogical analysis of clinical discourse may be a useful method to investigate change from the beginning to the end of therapy. PMID:23233845

Optical property degradation of anodic coatings in the Space Station low earth orbit

NASA Technical Reports Server (NTRS)

David, Kaia E.; Babel, Hank W.

1992-01-01

The anodic coatings and optical properties to be used for passive thermal control of the SSF are studied. Particular attention is given to the beginning-of-life optical properties for aluminum alloys suitable for structural and radiator applications, the statistical variation in the beginning-of-life properties, and estimates of the end-of-life properties of the alloys based on ultraviolet radiation testing and flight test results. It is concluded that anodic coatings can be used for thermal control of long life, low earth orbit spacecraft. Some use restrictions are defined for specific cases. Anodic coatings have been selected as baseline thermal control coating for large portions of the SSF.

LETTER TO THE EDITOR: Evidence for global mixing in real influenza epidemics

NASA Astrophysics Data System (ADS)

Bonabeau, Eric; Toubiana, Laurent; Flahault, Antoine

1998-05-01

The spatiotemporal behaviour of the spread of influenza in France has been studied, and algebraic spatial correlations (with exponent 0305-4470/31/19/001/img5) spanning the whole territory have been found to be present as soon as the number of reported cases begins to increase, about 15 - 25 weeks before the peak of the epidemic. This result is surprising, as one would expect long-range correlations, if any, only in the vicinity of the maximum incidence, whereas our observations suggest that there exists an underlying non-trivial spatial structure at the very beginning of the observed epidemic. The observed long-range correlations are in fact present in the spatial distribution of the population. Correlations in the number of cases normalized by local population density are characterized by 0305-4470/31/19/001/img6. This suggests that the spread of the epidemic is statistically uniform in space over a complex substrate that already contains the observed long-range correlations.

Undergraduate Students' Conceptions of Natural and Anthropogenic Climate Change

NASA Astrophysics Data System (ADS)

Trenbath, K. L.

2011-12-01

Scientists and educators strive to improve climate literacy throughout society, whether through communication of research findings or though classroom teaching. Despite these efforts, climate change misconceptions exist in students and the general public. When educators present evidence that contradicts misconceptions, students may begin to struggle with their inaccurate ideas and perhaps transition towards a scientifically-accepted understanding. These transitions, called conceptual change, can occur in college climate change courses. The purpose of this presentation is to describe college students' ideas of natural and anthropogenic climate change and the way these ideas change throughout a climate change course. This presentation is based on five case studies of undergraduate students in a large lecture-hall course dedicated to climate change. Each case study student represents a different level of climate change understanding at the beginning of the semester. These case studies and subsequent cross-case analyses result from a qualitative research study using interviews, field notes, artifact analysis, coding and categorization, and research memos. The cases show shifts in all five students' ideas of natural and anthropogenic climate change. During the first month of class, the three lower achieving students expressed uncertainty about the increase in average global temperatures due to anthropogenic climate change. At the end of the semester, these students explained that warming from climate change is natural, yet the rate of this warming is increasing due to human activities. Two of the lower achieving students constructed definitions of climate change different than the definition used by the professor in the classroom. These students solidified the idea that the term "climate change" describes the change that results from natural forcings only, while the term "global warming" describes change in the climate that results from human-caused forcings. Their constructed definition removes human-causes from association with the word "climate change", which may influence their climate change understanding. Of the two higher achieving students, one emphasized anthropogenic climate change at the beginning of the semester, but later focused on natural climate change during his interviews. The other high achieving student included tangential environmental topics in her descriptions of climate change throughout the entire semester, thus conflating climate change's definition. These alternative definitions of climate change indicate that the learners constructed hybrid conceptions in order to incorporate class content with their prior ideas. These hybrid conceptions indicate that the students' understandings lie somewhere between misconceptions and conceptual change. Since the students demonstrated these hybrid conceptions at the end of class, perhaps more time is needed for the students to process the information. These case studies identify the gaps the professor should address for conceptual change to fully occur.

This case study tests the possibility of prediction for 'success' (or 'winner') components of four stock & shares market indices in a time period of three years from 02-Jul-2009 to 29-Jun-2012.We compare their performance ain two time frames: initial frame three months at the beginning (02/06/2009-30/09/2009) and the final three month frame (02/04/2012-29/06/2012).To label the components, average price ratio between two time frames in descending order is computed. The average price ratio is defined as the ratio between the mean prices of the beginning and final time period. The 'winner' components are referred to the top one third of total components in the same order as average price ratio it means the mean price of final time period is relatively higher than the beginning time period. The 'loser' components are referred to the last one third of total components in the same order as they have higher mean prices of beginning time period. We analyse, is there any information about the winner-looser separation in the initial fragments of the daily closing prices log-returns time series.The Leave-One-Out Cross-Validation with k-NN algorithm is applied on the daily log-return of components using a distance and proximity in the experiment. By looking at the error analysis, it shows that for HANGSENG and DAX index, there are clear signs of possibility to evaluate the probability of long-term success. The correlation distance matrix histograms and 2-D/3-D elastic maps generated from ViDaExpert show that the 'winner' components are closer to each other and 'winner'/'loser' components are separable on elastic maps for HANGSENG and DAX index while for the negative possibility indices, there is no sign of separation.

Estimating the influenza vaccine effectiveness in elderly on a yearly basis using the Spanish influenza surveillance network--pilot case-control studies using different control groups, 2008-2009 season, Spain.

We conducted a case-control and screening method studies to estimate influenza vaccine effectiveness (IVE) in the age group >or=65 years, based on the Spanish Influenza Sentinel Surveillance System (SISSS). Cases (influenza laboratory-confirmed) were compared to influenza-negative ILI patients (test-negative) and patients without ILI since the beginning of the season (non-ILI). For the screening method, cases' vaccination coverage was compared to the vaccination coverage of the GPs' catchment population. The results suggested a protective effect of the vaccine against laboratory-confirmed influenza in elderly in 2008-2009. The screening method and the test-negative control designs enable estimating IVE using exclusively SISSS data. (c) 2010 Elsevier Ltd. All rights reserved.

Klein tunneling phenomenon with pair creation process

NASA Astrophysics Data System (ADS)

Wu, G. Z.; Zhou, C. T.; Fu, L. B.

2018-01-01

In this paper, we study the Klein tunneling phenomenon with electron-positron pair creation process. Pairs can be created from the vacuum by a supercritical single-well potential (for electrons). In the time region, the time-dependent growth pattern of the created pairs can be characterized by four distinct regimes which can be considered as four different statuses of the single well. We find that if positrons penetrate the single well by Klein tunneling in different statuses, the total number of the tunneling positrons will be different. If Klein tunneling begins at the initial stage of the first status i.e. when the sing well is empty, the tunneling process and the total number of tunneling positrons are similar to the traditional Klein tunneling case without considering the pair creation process. As the tunneling begins later, the total tunneling positron number increases. The number will finally settle to an asymptotic value when the tunneling begins later than the settling-down time t s of the single well which has been defined in this paper.

2008-07-04

The examination and comparison of forensic soil samples is discussed. The origin of a simple and easy to learn procedure used and modified by the authors is reviewed. The process begins with a preliminary observation, removal of artifacts, and sieving of each specimen. A specific size fraction is split into three fractions for color matching, polarized light microscopy (PLM) examination (particle counting) and optional gradient comparison. Next, several cases are reviewed in which the modified method was used to evaluate the likelihood of common origin for questioned and known specimens.

2017-01-01

The minimally invasive surgery for gastric cancer in Brazil has begun about two years after the first laparoscopic gastrectomy (LG) performed by Kitano in Japan, in 1991. Although the report of first surgeries shows the year of 1993, there was no dissemination of the technique until the years 2010. At that time with the improvement of optical devices, laparoscopic instruments and with the publications coming from Asia, several Brazilian surgeons felt encouraged to go to Korea and Japan to learn the standardization of the LG. After that there was a significant increase in that type of surgery, especially after the IRCAD opened a branch in Brazil. The growing interest for the subject led some services to begin their own experience with the LG and, since the beginning, the results were similar with those found in the open surgery. Nevertheless, there were some differences with the papers published initially in Japan and Korea. In those countries, the surgeries were laparoscopic assisted, meaning that, in the majority of cases, the anastomoses were done through a mini-incision in the end of the procedure. In Brazil since the beginning it was performed completely through laparoscopic approach due to the skills acquired by Brazilian surgeons in bariatric surgeries. Another difference was the stage. While in the east the majority of cases were done in T1 patients, in Brazil, probably due to the lack of early cases, the surgeries were done also in advanced cases. The initial experience of Zilberstein et al. revealed low rates of morbidity without mortality. Comparing laparoscopic and open surgery, the group from Barretos/IRCAD showed shorter surgical time (216×255 minutes), earlier oral or enteral feeding and earlier hospital discharge, with a smaller number of harvested lymph nodes (28 in laparoscopic against 33 in open surgery). There was no significant difference regarding morbidity, mortality and reoperation rate. In the first efforts to publish a multicentric study the Brazilian Gastric Cancer Association (BGCA) collected data from three institutions analyzing 148 patients operated from 2006 to 2016. There were 98 subtotal, 48 total and 2 proximal gastrectomies. The anastomoses were totally laparoscopic in 105, laparoscopic assisted in 21, cervical in 2, and 20 open (after conversion). The reconstruction methods were: 142 Roux-en-Y, two Billroth I, and three other types. The conversion rate was 13.5% (20/148). The D2 dissection was performed in 139 patients. The mean number of harvested lymph nodes was 34.4. If we take only the D2 cases the mean number was 39.5. The morbidity rate was 22.3%. The mortality was 2.7%. The stages were: IA—59, IB—14, IIA—11, IIB—15, IIIA—9, IIIB—19, IIIC—11 and stage IV—three cases. Four patients died from the disease and 10 are alive with disease. The participating services have already begun the robotic gastrectomy with satisfactory results. The intention of this group is to begin now a prospective multicentric study to confirm the data already obtained with the retrospective studies. PMID:28616601

Biomechanical Studies on Patterns of Cranial Bone Fracture Using the Immature Porcine Model.

PubMed

Haut, Roger C; Wei, Feng

2017-02-01

This review was prepared for the American Society of Mechanical Engineers Lissner Medal. It specifically discusses research performed in the Orthopaedic Biomechanics Laboratories on pediatric cranial bone mechanics and patterns of fracture in collaboration with the Forensic Anthropology Laboratory at Michigan State University. Cranial fractures are often an important element seen by forensic anthropologists during the investigation of pediatric trauma cases litigated in courts. While forensic anthropologists and forensic biomechanists are often called on to testify in these cases, there is little basic science developed in support of their testimony. The following is a review of studies conducted in the above laboratories and supported by the National Institute of Justice to begin an understanding of the mechanics and patterns of pediatric cranial bone fracture. With the lack of human pediatric specimens, the studies utilize an immature porcine model. Because much case evidence involves cranial bone fracture, the studies described below focus on determining input loading based on the resultant bone fracture pattern. The studies involve impact to the parietal bone, the most often fractured cranial bone, and begin with experiments on entrapped heads, progressing to those involving free-falling heads. The studies involve head drops onto different types and shapes of interfaces with variations of impact energy. The studies show linear fractures initiating from sutural boundaries, away from the impact site, for flat surface impacts, in contrast to depressed fractures for more focal impacts. The results have been incorporated into a "Fracture Printing Interface (FPI)," using machine learning and pattern recognition algorithms. The interface has been used to help interpret mechanisms of injury in pediatric death cases collected from medical examiner offices. The ultimate aim of this program of study is to develop a "Human Fracture Printing Interface" that can be used by forensic investigators in determining mechanisms of pediatric cranial bone fracture.

Towards a Neurodevelopmental Model of Clinical Case Formulation

PubMed Central

Solomon, Marjorie; Hessl, David; Chiu, Sufen; Olsen, Emily; Hendren, Robert

2009-01-01

Rapid advances in molecular genetics and neuroimaging over the last 10-20 years have been a catalyst for research in neurobiology, developmental psychopathology, and translational neuroscience. Methods of study in psychiatry, previously described as “slow maturing,” now are becoming sufficiently sophisticated to more effectively investigate the biology of higher mental processes. Despite these technological advances, the recognition that psychiatric disorders are disorders of neurodevelopment, and the importance of case formulation to clinical practice, a neurodevelopmental model of case formulation has not yet been articulated. The goals of this manuscript, which is organized as a clinical case conference, are to begin to articulate a neurodevelopmental model of case formulation, to illustrate its value, and finally to explore how clinical psychiatric practice might evolve in the future if this model were employed.

Westerly Wind Events in the Eastern Indian Ocean as a Precursor to El Nino: A Case Study for the 2002-03 El Nino

NASA Technical Reports Server (NTRS)

Curtis, Scott; Adler, Robert F.; Huffman, George J.; Gu, Guojun

2003-01-01

This paper extends the work of our previous study, which showed the potential of using precipitation in the eastern Indian Ocean to predict when an El Nino would begin. The paper begins by showing the successful prediction of the 2002-03 El Nino. However, precipitation is really used as a substitute for wind (storms are usually accompanied by heavy wind), because a popular hypothesis is that winds (especially % winds out of the West) stir up the ocean surface in the western Pacific sending currents of warm waters to the east Pacific where El Ninos form. This paper shows that it is typical for storms that produce strong winds in the western Pacific to have traveled from the Indian Ocean. We begin in the Indian Ocean looking at strong bursts of wind over several days. The number of windy days seems to increase in the months prior to El Nino. We examined these relationships in detail for November 2001 to April 2002, before the recent El Nino, using NASA's TRMM and QuikSCAT data. We found in one case that a warming of the eastern Indian Ocean occurred about 25 days before heavy rainfall formed. As the stormed moved eastward it was followed (6 days later) by strong winds out of the West. The entire storm system (and warming of the sea) moved eastward through a small strip of water between Indonesia and Australia, before reaching the western Pacific. Thus, this paper increases our understanding of the physical processes leading to the formation of El Nino.

Gibbon Aggression During Introductions: An International Survey.

PubMed

Harl, Heather; Stevens, Lisa; Margulis, Susan W; Petersen, Jay

2016-01-01

Little is known regarding the prevalence of aggression seen during introductions of captive gibbons (Hylobatidae). In this study, an online survey was developed to quantify and collect contextual details regarding the frequency and types of aggression seen during introductions of captive gibbons (Hylobatidae). Nineteen percent of institutions (17 institutions) reported observing aggression, and 6 of these institutions recorded multiple instances of aggression, though a vast majority of these cases resulted in mild injuries or none at all. The female was the primary aggressor in 23% of cases, the male was the primary aggressor in 58% of cases, and both were the primary aggressor in 1 case. Although these aggressive interactions were often not associated with a known cause, 27% of cases were associated with food displacement. In most cases, management changes, including trying new pairings, greatly reduced situational aggression, suggesting that individual personalities may play a factor in aggression. These data begin to explain the extent of aggression observed in captive gibbons; future studies will address possible correlations with aggression and introduction techniques.

Toxoplasmic Retinochoroiditis: Clinical Characteristics and Visual Outcome in a Prospective Study

PubMed Central

Curi, André Luiz Land; Benchimol, Eliezer Israel; Amendoeira, Maria Regina Reis

2016-01-01

Purpose To ascertain the clinical features and visual outcome of toxoplasma retinochoroiditis in a large series of cases. Subjects and Methods Two hundred and thirty subjects diagnosed with active toxoplasma retinochoroiditis were prospectively followed for periods ranging from 269 to 1976 days. All patients presented with active retinochoroiditis and positive IgG T. gondii serology at the beginning of the study and received a standardized drug treatment for toxoplasmosis, both in the first episode and in the subsequent recurrences. Results The group involved 118 (51.3%) men and 112 (48.7%) women, with ages ranging from 14 to 77 years, mean of 32.4 years (SD = 11.38). Primary retinochoroidal lesions were observed in 52 (22.6%) cases and active retinochoroiditis combined with old scars in 178 (77.4%) subjects at the beginning of the study. A hundred sixty-two recurrent episodes in 104 (45.2%) patients were observed during follow-up. New subclinical retinochoroidal lesions were detected in 23 of 162 (14.2%) recurrences episodes during the follow-up. Posterior segment complications were observed in 73 (31.7%) subjects. Retinochoroidal lesions adjacent to the optic nerve and in the macular area were observed in 27 of 40 (67.5%) cases of severe visual impairment (VA = 20/200 or worse). Conclusion Toxoplasma retinochoroiditis in this population had a high recurrence rate after an active episode. Severe visual impairment was associated with location of the retinochoroidal scar, recurrences and posterior segment complications. It is crucial to consider the location of the lesion in studies analyzing visual prognosis as a measure for treatment effectiveness and prevention strategies. PMID:27136081

Clinical Assessment and Diagnostics of Patients With Hand Disorders: A Case Study Approach.

PubMed

Leow, Mabel Qi He; Lim, Rebecca Qian Ru; Tay, Shian Chao

Clinical assessment of the hand is important for diagnosing underlying hand disorders. Using a case study approach, the clinical assessment for three disorders of the hands is presented: trigger finger (stenosing tenosynovitis), carpal tunnel syndrome, and ulnar-sided wrist injury (styloid impingement). We assess the annular one pulley and finger range of motion for patients with trigger finger. To diagnose for carpal tunnel syndrome, assessment for Tinel's sign, Phalen's sign, abductor pollicis brevis muscle bulk, two-point discrimination, and obtaining a nerve conduction study are performed. Assessment for ulnar-sided wrist injury includes wrist range of motion, assessment of distal radial ulnar joint stability, provocation tests, grip strength, x-ray, and magnetic resonance imaging. This article begins with a description of the hand and wrist anatomy. For each case study, the clinical history is described, followed by a discussion of the pathophysiology, clinical assessments, and diagnostic tests.

Low pressure hugoniot cusp in polymeric materials

NASA Astrophysics Data System (ADS)

Sheffield, S. A.; Bloomquist, D. D.

1982-04-01

It has previously been shown that polymethyl methacrylate (PMMA) exhibits a cusp in the shock Hugoniot at about 2.0 GPa which corresponds with the beginning of shock-induced polarization and the beginning of an exothermic reaction measured in thermocouple and resistivity gauge temperature studies. We now report results we have recently obtained from an ongoing study which indicate that other polymers have similar behavior at about the same pressure. Quartz gauge impact experiments have been performed using polypyro-ellitimide (Vespel) and polysulfone impactors to obtain Hugoniot information and the stress history at the impact plane. In the case of Vespel a slight Hugoniot cusp was observed at about 1.8 GPa which coincides with the start of shock-induced polarization. Polysulfone does not appear to have a cusp but does show stress relaxation at the impact plane beginning at about 1.8 GPa, again coinciding with the start of shock-induced polarization. It has been suggested earlier that the abnormal behavior in PMMA is the result of a shock-induced chemical reaction. This new information suggests that a stress of about 2 GPa is a threshold for shock-induced chemical reaction in several polymers.

Theory Versus Experiment: The Case of the Positron

NASA Astrophysics Data System (ADS)

Leone, Matteo

The history of positron discovery is an interesting case-study of complex relationship between theory and experiment, and therefore could promote understanding of a key issue on the nature of science (NoS) within a learning environment. As it is well known we had indeed a theory, P.A.M. Dirac's theory of the anti-electron (1931), before the beginning of the experiments leading to the experimental discovery of the positive electron (Anderson 1932). Yet, this case is not merely an instance of successful corroboration of a theoretical prediction since, as it will be shown, the man who made the discovery, Anderson, actually did not know from the start what to look for.

An uncommon clinical feature of IAN injury after third molar removal: a delayed paresthesia case series and literature review.

PubMed

Borgonovo, Andrea; Bianchi, Albino; Marchetti, Andrea; Censi, Rachele; Maiorana, Carlo

2012-05-01

After an inferior alveolar nerve (IAN) injury, the onset of altered sensation usually begins immediately after surgery. However, it sometimes begins after several days, which is referred to as delayed paresthesia. The authors considered three different etiologies that likely produce inflammation along the nerve trunk and cause delayed paresthesia: compression of the clot, fibrous reorganization of the clot, and nerve trauma caused by bone fragments during clot organization. The aim of this article was to evaluate the etiology of IAN delayed paresthesia, analyze the literature, present a case series related to three different causes of this pathology, and compare delayed paresthesia with the classic immediate symptomatic paresthesia.

Sanford, Michelle R

2015-02-01

Domestic pets are commonly found in the homes of decedents whose deaths are investigated by a medical examiner or coroner. When these pets become trapped with a decomposing decedent they may resort to feeding on the body or succumb to starvation and/or dehydration and begin to decompose as well. In this case report photographic documentation of cases involving pets and decedents were examined from 2009 through the beginning of 2014. This photo review indicated that in many cases the pets were cats and dogs that were trapped with the decedent, died and were discovered in a moderate (bloat to active decay) state of decomposition. In addition three cases involving decomposing humans and their decomposing pets are described as they were processed for time of insect colonization by forensic entomological approach. Differences in timing and species colonizing the human and animal bodies were noted as was the potential for the human or animal derived specimens to contaminate one another at the scene.

A Narrative in Search of a Methodology.

PubMed

Treloar, Anna; Stone, Teresa Elizabeth; McMillan, Margaret; Flakus, Kirstin

2015-07-01

Research papers present us with the summaries of scholars' work; what we readers do not see are the struggles behind the decision to choose one methodology over another. A student's mental health portfolio contained a narrative that led to an exploration of the most appropriate methodology for a projected study of clinical anecdotes told by nurses who work in mental health settings to undergraduates and new recruits about mental health nursing. This paper describes the process of struggle, beginning with the student's account, before posing a number of questions needing answers before the choice of the most appropriate methodology. We argue, after discussing the case for the use of literary analysis, discourse analysis, symbolic interactionism, hermeneutics, and narrative research, that case study research is the methodology of choice. Case study is frequently used in educational research and is sufficiently flexible to allow for an exploration of the phenomenon. © 2014 Wiley Periodicals, Inc.

The contribution of case study design to supporting research on Clubhouse psychosocial rehabilitation.

PubMed

Raeburn, Toby; Schmied, Virginia; Hungerford, Catherine; Cleary, Michelle

2015-10-01

Psychosocial Clubhouses provide recovery-focused psychosocial rehabilitation to people with serious mental illness at over 300 sites in more than 30 countries worldwide. To deliver the services involved, Clubhouses employ a complex mix of theory, programs and relationships, with this complexity presenting a number of challenges to those undertaking Clubhouse research. This paper provides an overview of the usefulness of case study designs for Clubhouse researchers; and suggests ways in which the evaluation of Clubhouse models can be facilitated. The paper begins by providing a brief explanation of the Clubhouse model of psychosocial rehabilitation, and the need for ongoing evaluation of the services delivered. This explanation is followed by an introduction to case study design, with consideration given to the way in which case studies have been used in past Clubhouse research. It is posited that case study design provides a methodological framework that supports the analysis of either quantitative, qualitative or a mixture of both types of data to investigate complex phenomena in their everyday contexts, and thereby support the development of theory. As such, case study approaches to research are well suited to the Clubhouse environment. The paper concludes with recommendations for future Clubhouse researchers who choose to employ a case study design. While the quality of case study research that explores Clubhouses has been variable in the past, if applied in a diligent manner, case study design has a valuable contribution to make in future Clubhouse research.

Microbial flora of tears of orthokeratology patients, and microbial contamination of contact lenses and contact lens accessories.

PubMed

Boost, Maureen V; Cho, Pauline

2005-06-01

The purpose of this study is to determine if there are changes in the ocular flora of overnight orthokeratology (ortho-k) patients, and the levels of contamination of their lenses and lens accessories, and to correlate compliance with levels of contamination. Normal ocular flora of 41 subjects was determined twice before commencing ortho-k lens wear by culture of the lower conjunctiva. Further specimens were collected on six follow-up visits after beginning lens wear, as were samples from their lenses, cases, and suction holders. A questionnaire on lens care was administered after the fifth visit. Three subjects provided conjunctival samples yielding Staphylococcus aureus on one occasion before lens wear, one being positive for this organism after beginning lens wear. Of 38 subjects yielding no growth or only normal eye flora before use, 28 remained free of ocular pathogens after beginning lens wear. Only four subjects had positive cultures on more than one occasion after lens wear. There was no significant difference in isolation levels of pathogens with lens wear (p = 0.423). Lens culture of 54% of subjects yielded no growth or normal flora only; lenses of 16 subjects yielded potential pathogens, including three subjects contaminated on more than one occasion. Lens isolates did not match the organisms transiently colonizing the eye. Lens case, the most frequently contaminated item, was associated with lens contamination (p < 0.001), the same organism being isolated from both items in 11 subjects. Lens suction holder was less frequently contaminated. Neither lens case nor suction holder contamination was associated with isolates from the eye. Reported good compliance correlated with lack of contamination in all but one subject. The most frequent breaches in the lens care protocol were failure to clean, disinfect, and replace the lens case. Ocular flora was not altered by ortho-k lens wear over an extended period, and patients remained free of infection. Contaminants identified were generally of a transient nature. Most patients had significant contamination of at least one item, most frequently the lens case. Lens case isolates were significantly associated with those from the lens. The majority of patients reporting good compliance had low or no contamination of their lenses and accessories.

Nanostructure control: Nucleation and diffusion studies for predictable ultra thin film morphologies

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

Hershberger, Matthew

This thesis covers PhD research on two systems with unique and interesting physics. The first system is lead (Pb) deposited on the silicon (111) surface with the 7x7 reconstruction. Pb and Si are mutually bulk insoluble resulting in this system being an ideal case for studying metal and semiconductor interactions. Initial Pb deposition causes an amorphous wetting layer to form across to surface. Continued deposition results in Pb(111) island growth. Classic literature has classified this system as the Stranski-Krastanov growth mode although the system is not near equilibrium conditions. Our research shows a growth mode distinctly different than classical expectationsmore » and begins a discussion of reclassifying diffusion and nucleation for systems far away from the well-studied equilibrium cases.« less

Social media campaigns that make a difference: what can public health learn from the corporate sector and other social change marketers?

Freeman, Becky; Potente, Sofia; Rock, Vanessa; McIver, Jacqueline

2015-03-30

A great deal of enthusiasm and interest exists in using social media for public health communications, but few research studies have examined its success in promoting and adopting protective health behaviours. To begin to understand how best to develop effective online social marketing campaigns, this paper provides a summary of success factors and key lessons learnt from selected social media campaign case studies. Case study review Methods: A selection of case studies was reviewed for lessons in campaign development, delivery and evaluation from both the corporate and public health sectors. Information about the objective of the campaign, the tactics used and the lessons learnt was extracted from each case study. Lessons learnt from across the case studies were then sorted according to themes. Lessons from the nine case studies selected were categorised into eight themes: planning, use of social media tools, community, content, personal benefits, promotion, costs and challenges. Outcome evaluation data were lacking in the case studies. Overall, the nine case studies show that social media hold promise in changing user behaviours and that social media are highly effective in recruiting participants and motivating them to take small, concrete actions. The case studies also demonstrate that there is room in social media for targeted, inexpensive, small-scale projects, as well as large, well-funded, mass-reach marketing blitzes. Social media campaign process and impact evaluation measures are readily available. Outcome evaluation models and measures are needed to better assess the effectiveness of social media campaigns in changing health behaviours.

Supporting Beginning Teacher Planning and Enactment of Investigation-based Science Discussions: The Design and Use of Tools within Practice-based Teacher Education

NASA Astrophysics Data System (ADS)

Kademian, Sylvie M.

Current reform efforts prioritize science instruction that provides opportunities for students to engage in productive talk about scientific phenomena. Given the challenges teachers face enacting instruction that integrates science practices and science content, beginning teachers need support to develop the knowledge and teaching practices required to teach reform-oriented science lessons. Practice-based teacher education shows potential for supporting beginning teachers while they are learning to teach in this way. However, little is known about how beginning elementary teachers draw upon the types of support and tools associated with practice-based teacher education to learn to successfully enact this type of instruction. This dissertation addresses this gap by investigating how a practice-based science methods course using a suite of teacher educator-provided tools can support beginning teachers' planning and enactment of investigation-based science lessons. Using qualitative case study methodologies, this study drew on video-records, lesson plans, class assignments, and surveys from one cohort of 22 pre-service teachers (called interns in this study) enrolled in a year-long elementary education master of the arts and teaching certification program. Six focal interns were also interviewed at multiple time-points during the methods course. Similarities existed across the types of tools and teaching practices interns used most frequently to plan and enact investigation-based discussions. For the focal interns, use of four synergistic teaching practices throughout the lesson enactments (including consideration of students' initial ideas; use of open-ended questions to elicit, extend, and challenge ideas; connecting across students' ideas and the disciplinary core ideas; and use of a representation to organize and highlight students' ideas) appeared to lead to increased opportunities for students to share their ideas and engage in data analysis, argumentation and explanation construction. Student opportunities to engage in practices that prioritize scientific discourse also occurred when interns were using dialogic voice and the tools designed to foster development of teacher knowledge for facilitating investigation-based science discussions. However, several intern characteristics likely moderated or mediated intern use of tools, dialogic voice, and productive teaching practices to capitalize on student contributions. These characteristics included intern knowledge of the science content and practices and initial beliefs about science teaching. Missed opportunities to use a combination of several teaching practices and tools designed to foster the development of knowledge for science teaching resulted in fewer opportunities for students to engage in data analysis, argumentation based on evidence, and construction of scientific explanations. These findings highlight the potential of teacher-educator provided tools for supporting beginning teachers in learning to facilitate investigation-based discussions that capitalize on student contributions. These findings also help the field conceptualize how beginning teachers use tools and teaching practices to plan and enact investigation-based science lessons, and how intern characteristics relate to tool use and planned and enacted lessons. By analyzing the investigation-based science lessons holistically, this study begins to unpack the complexities of facilitating investigation-based discussions including the interplay between intern characteristics and tool use, and the ways intern engagement in synergistic teaching practices provide opportunities for students to engage in data analysis, explanation construction, and argumentation. This study also describes methodological implications for this type of whole-lesson analysis and comments on the need for further research investigating beginning teachers' use of tools over time. Finally, I propose the need for iterative design of scaffolds to further support beginning teacher facilitation of investigation-based science lessons.

Poliovirus Studies during the Endgame of the Polio Eradication Program.

PubMed

Arita, Minetaro

2017-01-24

Since the beginning of Global Polio Eradication Initiative in 1988, poliomyelitis cases caused by wild poliovirus (PV) have been drastically reduced, with only 74 cases reported in 2 endemic countries in 2015. The current limited PV transmission suggests that we are in the endgame of the polio eradication program. However, specific challenges have emerged in the endgame, including tight budget, switching of the vaccines, and changes in biorisk management of PV. To overcome these challenges, several PV studies have been implemented in the eradication program. Some of the responses to the emerging challenges in the polio endgame might be valuable in other infectious diseases eradication programs. Here, I will review challenges that confront the polio eradication program and current research to address these challenges.

Posterior Circulation Moyamoya Disease versus Primitive Vertebral-Basilar Artery System Moyamoya Disease: New Classification of Moyamoya Disease from the Perspective of Embryology.

PubMed

Tan, Cunxin; Duan, Ran; Ye, Xun; Zhang, Dong; Wang, Rong

2016-12-01

Moyamoya disease (MMD) is a chronic cerebrovascular disorder with little known etiology. We aim to propose a new classification system for MMD from the perspective of embryology. MMD patients' digital subtraction angiograms were retrospectively analyzed. Every angiogram was analyzed to find the abnormal vessels and from which part of the posterior cerebral artery (PCA) the lesions begin. In 262 MMD cases, 32 pediatric patients had PCA involvement, of which 17 were male and 15 were female; 68 adults had PCA involvement, of which 33 were male and 35 were female. The initially affected part of the PCA was compared between sexes and between pediatric and adult patients, and the findings are not statistically significant (P = 0.233, P = 0.855, P = 0.343, respectively). However, of the 100 cases with PCA involvement, only 4 had the lesions begin from the first part of the PCA, and all of the 4 cases had the basilar artery lesions. All the other 96 cases had the lesions begin from the second part of the PCA or from the posterior communication artery, which is derived from the caudal ramus of the primitive intracarotid artery, leaving the first part of the PCA and basilar artery excluded from affection. MMD should be classified into primitive intracarotid artery system-involved type and primitive vertebral basilar artery system-involved type. The reason that the vertebral basilar artery is so rarely involved in MMD might be because of its late development in the brain. Copyright © 2016 Elsevier Inc. All rights reserved.

Using Case Studies to Promote Student Engagement in Primary Literature Data Analysis and Evaluation

2017-01-01

Analyzing and evaluating primary literature data is a common learning objective in undergraduate neuroscience courses. However, students with more clinically focused career goals often dismiss the relevance of evaluating basic neuroscience literature. Here, we describe using case studies to promote student engagement in primary literature in a cellular and molecular neuroscience course. Two example literature-based case studies are provided: Untwisting Pretzel Syndrome, a neurodevelopment case exploring synapse formation in a pretzel syndrome patient, and The Trials of ALS, a neurodegeneration case exploring axon degeneration and repair in an amyotrophic lateral sclerosis patient. These cases were assigned after neurodevelopment and neurodegeneration lectures covering key concepts. Both cases begin by introducing the patient and hypothesizing symptoms and diagnoses, followed by scenes incorporating primary data to illustrate disease pathogenesis and treatments. Students complete questions embedded in these cases as homework, and class time is used to discuss their answers. Discussion emphasizes that there can be multiple “correct” answers, and the best answers are accurate and well-supported. Accordingly, students edit their answers in class, and these annotations are factored into a pass/fail grade on the case. Additional scenes and questions from the same case studies are used on the course’s take-home exams, thereby allowing students to practice primary data analysis and evaluation before a graded assignment. Student evaluations support literature-based case studies as an effective learning tool, with students identifying cases as the most valuable aspect of the course, and reporting increased confidence in understanding cellular and molecular neuroscience.

Science education for empowerment and social change: a case study of a teacher educator in urban Pakistan

NASA Astrophysics Data System (ADS)

Zahur, Rubina; Calabrese Barton, Angela; Upadhyay, Bhaskar Raj

2002-09-01

In this manuscript we focus on the question, 'What should be the purpose of science education for children of the very poor class in caste-oriented developing countries such as Pakistan?' In other words, in a country where the literacy rate hovers around 10 per cent for the poorest segment of society and where there is no expectation that children will complete primary school, of what importance is primary science education and to what end should it be offered in schools? We begin a conversation around this question by presenting, in this manuscript, a case study of one teacher educator whose beliefs and practices sharply deviate from the norm - she believes science education ought to be about empowering students to make physical and political changes in their community. In particular, using the rich, contextual interview and observational data generated through case study, we show how Haleema's (pseudonym) orientation to science teacher education are buttressed by three fundamental beliefs: that low levels of literacy and school achievement among poor children have as much to do with poor families' lack of power/influence on the purposes and processes of schooling as it has to do with opportunities and resources; that school science can begin to address inequalities in power by fostering a kind of scientific literacy among children that leads to individual and community empowerment around health and environmental issues, the very science-related issues that divide quality of life and opportunity for poor families; and that teacher education programmes can play a role in transforming a society's views about how science and scientific practices might play a role in bringing communities together to effect change for the better.

The control effect in a detached laminar boundary layer of an array of normal synthetic jets

Valenzuela Calva, Fernando; Avila Rodriguez, Ruben

2016-11-01

In this work, 3D numerical simulations of an array of three normal circular synthetic jets embedded in an attached laminar boundary layer that separates under the influence of an inclined flap are performed for flow separation control. At the beginning of the present study, three cases are used to validate the numerical simulation with data obtained from experiments. The experimental data is chosen based on the cases which presented higher repeatability and reliability. Simulations showed reasonable agreement when compared with experiments. The simulations are undertaken at three synthetic jet operating conditions, i.e. Case A: L = 2, VR = 0.32; Case B: L = 4, VR = 0.64 and Case C: L = 6, VR = 0.96. The vortical structures produced for each synthetic jet operating condition are hairpin vortices for Case A and tilted vortices for Case B and C, respectively. By examining the spatial wall shear stress variations, the effect on the boundary layer prior to separation of the middle synthetic jet is evaluated. For effective flow control, produced at a relatively low the finding from this study suggests that hairpin vortical structures are more desirable structures. Universidad Nacional Autonoma de Mexico.

[Relevance of parasitological examinations for the clinical course, epidemiology and prevention of alveolar echinococcosis - experiences of more than two decades in Austria].

PubMed

Auer, Herbert

2006-01-01

Alveolar echinococcosis has been known in Austria since 1854. At the beginning of the 20th century the Austrian researcher on echinococcosis, Adolf Posselt, has realized already the enormous medical relevance of serological tests for the diagnosis of alveolar echinococcosis as well as for preventive purposes. Since the beginning of the 1980ies a long-term study about the epidemiology and serodiagnosis of alveolar echinococcosis has started in the Department of Medical Parasitology of the Clinical Institute of Hygiene and Medical Microbiology of the University of Vienna. Today a highly sensitive enzyme-linked immunosorbent assay as well as a highly specific westernblot system are available for the serological diagnosis of human alveolar echinococcosis cases, for the serological monitoring of the disease as well as for seroepidemiological and preventive medical studies. In addition, molecular biological tools for the detection of E. multilocularis (as well as E. granulosus strain) specific DNA in surgical resected and bioptic materials complete our diagnostic spectrum of methods.

Data concerning the reliability of robotic systems are scarce, especially for general surgery. The aim of this study was to assess the incidence and consequences of robotic malfunction in a teaching institution. From January 2006 to September 2012, 526 consecutive robotic general surgical procedures were performed. All failures were prospectively recorded in a computerized database and reviewed retrospectively. Robotic malfunctions occurred in 18 cases (3.4%). These dysfunctions concerned the robotic instruments in 9 cases, the robotic arms in 4 cases, the surgical console in 3 cases, and the optical system in 2 cases. Two malfunctions were considered critical, and 1 led to a laparoscopic conversion (conversion rate due to malfunction, .2%). Overall, there were more dysfunctions at the beginning of the study period (2006 to 2010) than more recently (2011 to 2012) (4.2% vs 2.6%, P = .35). The robotic system malfunction rate was low. Most malfunctions could be resolved during surgery, allowing the procedures to be completed safely. With increased experience, the system malfunction rate seems to be reduced.

The Scopes trial and creation thought since 1925

NASA Astrophysics Data System (ADS)

Spaid, Mark Richard

The purpose of this study was to examine the role of the Scopes Trial of 1925 as the beginning of the battle between Creation Thought and Evolutionary Science in the public school classrooms. Historical analysis of events, legislation and a legal case study was used to synthesize the ideas and philosophies that guided events this century leading up the trial in Dayton, Tennessee during July of 1925. The study examined the development of the concept of a wall of separation between Church and State that began with Thomas Jefferson and James Madison and developed into the key component of the First Amendment to the U. S. Constitution. This concept was applied to the case analysis, legislation and school district policies regarding Creation and Evolution. The concepts of Creation and Evolution were examined and compared as a basis for understanding the conflict that exists between the Religious Right and the scientific community. The main personalities and their motives on both sides were highlighted because of the fact that the conflict still continues. The study sought solutions for practicing administrators who are faced with the controversy of Creation and Evolution in their schools. The question that guided the study was, "Is Accommodation possible or is Separation necessary?" The study examined legislation and court cases seeking the right answer for schools in their constant struggle with the two diametrically opposed philosophies. Analysis of the historical evidence and the events surrounding the issue since the inception of the United States concluded that there is no room for Accommodation with the First Amendment. Separation has been and should continue to be the guiding principle whenever the line between Church and State begins to blur. The collaboration between Church and State can prove harmful for both and the best way to insure their survival and proliferation is to keep them separate.

In the beginning of 2002 there were an unusually high number of sudden unexpected infant deaths. A prospective study was started to determine the cause of unexpected deaths in infants younger than 1 year. Investigate the possible causes of sudden and unexpected death in infants of Bariloche and surrounding areas, using a protocol created for that purpose. All infants under 1 year of age who died unexpectedly between May 2002 and April 2007 were studied. A complete physical examination, a thorough interrogation to the parents and an autopsy were performed. According to the findings a definitive diagnosis was made on each case. During the study period 10 infants younger than 1 year died. One case was excluded because the autopsy could not be done. The mean age was 74 days, 6 were males. All died while sleeping and no sign of disease were noticed in any case. In 6 cases, the autopsy findings explained the death. In the 3 others no cause for the death was found. The implementation of this protocol allowed to find out the cause of death in 6 cases, that could not have been achieved without the autopsy.

Since Oct. 1981 a new systemic antifungal drug Ketoconazole is available in the Federal Republic of Germany that has proven effective even in severe cases with fungal infections. This case-study will call attention on a rare but important side effect, namely Ketoconazole induced hepatitis. As an acute icteric viral hepatitis, type Non-A-Non-B-hepatitis possibly misdiagnosed only a carefully compiled history of the recent intake of drugs points at the real cause of hepatitis. In our case-report we observed a considerable increase in serum enzymes, especially GOT, GPT and GLDH after a drug-challenge with two tablets. We recommend so-called liver functions tests 2 to 3 weeks after beginning of therapy and further-on in monthly intervals. Histologically at that time toxic hydropic changes of the liver cells and a mesenchymal reaction with portal and intralobular mainly eosinophilic infiltration could be established. The serum enzymes came to normal only after 12 weeks.

Tracking the recovery of consciousness from coma

Laureys, Steven; Boly, Mélanie; Maquet, Pierre

2006-01-01

Predicting the chances of recovery of consciousness and communication in patients who survive their coma but transit in a vegetative state or minimally conscious state (MCS) remains a major challenge for their medical caregivers. Very few studies have examined the slow neuronal changes underlying functional recovery of consciousness from severe chronic brain damage. A case study in this issue of the JCI reports an extraordinary recovery of functional verbal communication and motor function in a patient who remained in MCS for 19 years (see the related article beginning on page 2005). Diffusion tensor MRI showed increased fractional anisotropy (assumed to reflect myelinated fiber density) in posteromedial cortices, encompassing cuneus and precuneus. These same areas showed increased glucose metabolism as studied by PET scanning, likely reflecting the neuronal regrowth paralleling the patient’s clinical recovery. This case shows that old dogmas need to be oppugned, as recovery with meaningful reduction in disability continued in this case for nearly 2 decades after extremely severe traumatic brain injury.

Inquiry Teaching in High School Chemistry Classrooms: The Role of Knowledge and Beliefs

NASA Astrophysics Data System (ADS)

Roehrig, Gillian H.; Luft, Julie A.

2004-10-01

"Science as inquiry" is a key content standard in the National Science Education Standards, yet implementation of inquiry-based teaching is rare in secondary chemistry classrooms. This paper is the result of a study conducted to understand factors that effect the inquiry-based instruction of ten novice secondary chemistry teachers. The study focused on the influence of teaching beliefs and content knowledge on the instructional practices of these ten teachers. Case and cross-case comparisons revealed that chemistry teachers' intentions to implement inquiry teaching were strongly influenced by their teaching beliefs rather than their knowledge of chemistry. The quality of inquiry lessons, however, was found to depend on the teachers' knowledge of chemistry content. This study reinforces the need for chemistry-focused inservice training for beginning chemistry teachers that focuses on both inquiry teaching strategies and teaching beliefs.

The Teaching of Physics in Cuba from Colonial Times to 1959

NASA Astrophysics Data System (ADS)

Altshuler, José; Baracca, Angelo

The present paper will concentrate on the study of the first one and a half centuries of the teaching of physics in Cuba, starting from the early interest or activities in this. To provide the appropriate context, we will begin by going back in time to the early local signs of a modern scientific sensitivity, scornful of scholastic teaching and fond of experimental approaches, under the belated but stimulating influence of the European Enlightenment. We will go over individual cases during the initial phase of the country's academic physics in some detail, firstly during the initial period of colonial rule, and then from the beginning of the twentieth century to the triumph of the 1959 Revolution earlier that year. We thus hope to make the fundamental aspects of our subject reasonably consistent and abiding, even though further historical research may eventually throw new light on relevant details, personalities and events.

The effects of brain lesions on the "hopping reaction" in newborn and adult rabbits: a model for studying age dependent recovery.

van Hof, M W; Hobbelen, J F; Gramsbergen, A

1990-01-01

In 5 groups of rabbits (0-1, 2-3, 4-5, 6-7 and 12-13 weeks old) the left frontal, parieto-temporal and occipital cortex were removed. Beginning two weeks after the operations the hopping reaction was tested during 15 weeks. It was found in the groups operated 0-1, 2-3 and 4-5 weeks after birth, that the hopping reaction developed normally. This was not the case in the animals operated 6-7 and 12-13 weeks after birth. Brightness descrimination with the left and right eye was tested in the same animals, beginning 12 weeks after the operation. Contrary to the motor system, no age-development recovery was found in the visual system. In all age groups, brightness discrimination with the eye contralateral to the lesion was impaired.

Gravitational lensing of active galactic nuclei.

PubMed

Hewitt, J N

1995-12-05

Most of the known cases of strong gravitational lensing involve multiple imaging of an active galactic nucleus. The properties of lensed active galactic nuclei make them promising systems for astrophysical applications of gravitational lensing; in particular, they show structure on scales of milliseconds of arc to tens of seconds of arc, they are variable, and they are polarized. More than 20 cases of strong gravitational lenses are now known, and about half of them are radio sources. High-resolution radio imaging is making possible the development of well-constrained lens models. Variability studies at radio and optical wavelengths are beginning to yield results of astrophysical interest, such as an independent measure of the distance scale and limits on source sizes.

Many recommended best practices exist for clinical and community diabetes management and prevention. However, in many cases, these recommendations are not being fully utilized. It is useful to gain a sense of currently utilized and needed practices when beginning a partnership building effort to ameliorate such practice problems. The purpose of this study was to assess current practices in clinical settings within the Brazos Valley in preparation for beginning a community-based participatory research project on improving diabetes prevention and management in this region. Fifty-seven physicians with admission privileges to a regional health system were faxed a survey related to current diabetes patient loads, knowledge and implementation of diabetes-related best practices, and related topics. Both qualitative and quantitative examination of the data was conducted. Fifteen percent of responding providers indicated they implemented diabetes prevention best practices, with significant differences between primary-care physicians and specialists. Respondents indicated a need for educational and counseling resources, as well as an increased health-care workforce in the region. The utilization of a faxed-based survey proved an effective means for assessing baseline data as well as serving as a catalyst for further discussion around coalition development. Results indicated a strong need for both clinical and community-based services regarding diabetes prevention and management, and provided information and insight to begin focused community dialogue around diabetes prevention and management needs across the region. Other sites seeking to begin similar projects may benefit from a similar process.

Making Judgments: How Blame Mediates the Influence of Rape Myth Acceptance in Police Response to Sexual Assault.

Venema, Rachel M

2016-08-01

As research continues to describe negative experiences and high case attrition within sexual assault cases reported to the police, it is important to better understand the role of first-responding police officers. This study surveyed a sample of sworn police officers ( N = 174) from one department in a midsized city in the Great Lakes region to examine the effect of individual police officer characteristics, rape myth acceptance (RMA), attributions of blame, and case characteristics from a hypothetical vignette, on officer perceptions of a "good" case and behavioral intentions. Results found that although RMA predicts both perceptions of the case and behavioral intentions to respond in ways indicative of perceived seriousness, RMA is mediated by attributions of suspect blame. Victim alcohol use was found to decrease an officer's likelihood of responding more vigorously, showing less likelihood of calling a detective or arresting the suspect, if identified. Future research should begin to connect not only case characteristics but also individual police officer characteristics, attitudes, and attributions of blame, with real case outcomes, in addition to hypothetical scenarios.

2009-01-01

Juvenile idiopathic arthritis is a term that encompasses all forms of arthritis that begin before the age of 16 years, persist for more than 6 weeks and are of unknown cause. Dry synovitis is still not completely understood nor commonly described. It is associated with juvenile idiopathic arthritis and must be considered in patients with minimal swelling but pain and stiffness along with flexion contractures as well as other evidence of an inflammatory process (lab changes and/or other symptoms, such as uveitis or rash), and often follow a destructive course. The authors present a case of a brazilian child with a rheumatoid factor- negative polyarthritis compatible with the subtype dry synovitis, who had great clinical and functional improvement after participation in rehabilitation activities and beginning of pharmacological treatment usually used in Juvenile idiopathic arthritis, including immunossuppressive therapy.

Scientific reason for data generation: to serve as the base-case scenario for the BT16 volume 1 agricultural scenarios to compare these projections of potential biomass supplies against a reference case (agricultural baseline 10.11578/1337885). The simulation runs from 2015 through 2040; a starting year of 2014 is used but not reported. How each parameter was produced (methods), format, and relationship to other data in the data set: This exogenous price simulations (also referred to as “specified-price” simulations) introduces a farmgate price, and POLYSYS solves for biomass supplies that may be brought to market in response to these prices. In specified-price scenarios, a specified farmgate price is offered constantly in all counties over all years of the simulation. This simulation begins in 2015 with an offered farmgate price for primary crop residues only between 2015 and 2018 and long-term contracts for dedicated crops beginning in 2019. Expected mature energy crop yield grows at a compounding rate of 1% beginning in 2016. The yield growth assumptions are fixed after crops are planted such that yield gains do not apply to crops already planted, but new plantings do take advantage of the gains in expected yield growth. Instruments used: Policy Analysis System –POLYSYS (version POLYS2015_V10_alt_JAN22B), an agricultural policy modeling system of U.S. agriculture (crops and livestock), supplied by the University of Tennessee Institute of Agriculture, Agricultural Policy Analysis Center.

INTRODUCTION. The Guillan-Barre syndrome is the most frequent case of acute flacid paralysis in children. The diagnostic criteria differ according to the demyelinating or axonal variant and the prevalence by geographical area. The electro-myographic study permits identifying variants, evaluating the prognosis and predicting the evolution, is in addition an objective tool for the monitoring. AIM. To describe the electromyographic characteristics of the Guillain-Barre syndrome evaluated in hospital and its classification by physiopathological pattern. PATIENTS AND METHODS. All the cases diagnosed between 2005 and 2012 are included. Studies of motor and sensitive nervous conduction and F waves in 14 girls and 11 boys between 1 and 13 years of age. RESULTS. 19 cases of acute inflammatory demyelinating polyneuropathy (AIDP) and five of acute motor axonal neuropathy (AMAN) were diagnosed. The electromyogram was performed between 1 and 30 days after the beginning of symptoms. In AIDP cases, multifocal demyelination, four of them with the preserved sural and 13 with alteration and absence of F wave were objectified. In the cases of AMAN, four had low amplitude potential and in one of them they were not evoked. CONCLUSIONS. The demyelinating form of the illness is the most frequent although the high number of AMAN cases stands out, probably related to the population object of study. The evolution was favorable in three cases of motor axonal neuropathy and in 15 accute demyelinating polyneuropathy. In four cases the symptoms became chronic; three of them with persistent demyelination a similar occurrence in other studies with children.

The temple and the plane tree: rationality and cult at the beginnings of western medicine.

There are multiple interrelationships between science, medicine and visual arts. This article discusses aspects of architecture associated with the Greek healing cult of Asklepios, the case in point being the Asklepios temple on the island of Kos in the Aegean. Further, the cult is contrasted with the beginnings of the observation-based medicine practised by Hippocrates (460-c.370 BC). Finally, it is suggested that including elements of visual arts in medical education is consistent with the aims of the new medical curricula.

The aim of this trial was to evaluate the effects of polyunsaturated fatty acid (PUFA) supplementation in different-stages atopic dogs fed on a controlled diet. Twenty-two non-seasonal atopic dogs of different breeds and ages were included in the 2-month trial. All the patients were given an essential fatty acid (EFA) supplementation [17 mg/kg eicosapentaenoic acid (EPA) + 5 mg/kg docosahexaenoic acid (DHA) + 35 mg/kg gammalinolenic acid (GLA)], the global (diet + supplementation) omega-6 to omega-3 ratio was 5.5-1. Two groups of dogs were considered: group A 'pre-immunotherapy' (15 cases) included dogs with early stages atopy, which had not been submitted to any treatment yet; group B 'post-immunotherapy' (seven cases) included dogs with chronic atopy immunotherapy non-responsive. Clinical evaluations were performed at the beginning, on day 30 and at the end of the trial. Blood serum fatty acids profile was determined at the beginning and at the end of the study. Better clinical results were obtained in group A, a great difference was found between the two groups on pruritus score. Serum arachidonic acid (AA) was significantly lower at the end of the trial in group A while GLA was significantly higher in group B. We hypothesized that different-stages atopic dogs could have different response to EFA supplementation, maybe because of a different fatty acids metabolism. Early stages cases seem to be more responsive to EFA supplementation.

Veterinary students are challenged to develop new, nonlinear ways of thinking as they learn diagnostic reasoning skills. To support this process, we use real-life cases in our clinical pathology course. Changes in student perceptions regarding the use of cases and changes in study strategies over time have not been previously investigated or compared to student grades. Students participated in three voluntary online surveys that included 4-point Likert scale questions and open-ended questions on the helpfulness of cases for learning and study strategies used during the course. We used Friedman tests to detect any differences in perceptions over time; McNemar's test and "Wilcoxon signed-rank tests were used to detect any differences in study strategies over time. Fisher's exact tests'were used to examine the association between the Likert scale responses and grades in quartiles. Before beginning the course, 29% of students responded that cases were very helpful to their learning, with similar "responses for helpfulness in applying course material and grasping important concepts. There was a significant trend of increasing positivity over the duration of the course, with 74% responding that cases were very helpful at the end of the course. The most-reported study strategy was working individually on cases before the midterm (74% of students), and the most helpful study strategy was attending class regularly (88% reported it as very "helpful). Study strategies did not change significantly over time. Overall, perceptions and study strategies did not vary significantly with grades.

Analysis Impact of Distributed Generation Injection to Profile of Voltage and Short-Circuit Fault in 20 kV Distribution Network System

2018-01-01

This study was a case study in PT. PLN (Ltd.) APJ Bandung area with the subject taken was the installation of distributed generation (DG) on 20-kV distribution channels. The purpose of this study is to find out the effect of DG to the changes in voltage profile and three-phase short circuit fault in the 20-kV distribution system with load conditions considered to be balanced. The reason for this research is to know how far DG can improve the voltage profile of the channel and to what degree DG can increase the three-phase short circuit fault on each bus. The method used in this study was comparing the simulation results of power flow and short-circuit fault using ETAP Power System software with manual calculations. The result obtained from the power current simulation before the installation of DG voltage was the drop at the end of the channel at 2.515%. Meanwhile, the three-phase short-circuit current fault before the DG installation at the beginning of the channel was 13.43 kA. After the installation of DG with injection of 50%, DG power obtained voltage drop at the end of the channel was 1.715% and the current fault at the beginning network was 14.05 kA. In addition, with injection of 90%, DG power obtained voltage drop at the end of the channel was 1.06% and the current fault at the beginning network was 14.13%.

Case managers' expectations about employment for people with psychiatric disabilities.

PubMed

Abraham, Kristen M; Stein, Catherine H

2009-01-01

The importance of employment in lives of people with psychiatric disabilities is well documented. Yet, the role of case managers in facilitating or inhibiting employment opportunities for consumers is only beginning to be understood. This study examined the psychometric properties of a newly developed self-report measure designed to assess case managers' employment-related expectations of consumers. Psychometric properties of a 24-item self-report measure, Expectations for the Employability of People with Serious Mental Illness (EESMI), were examined using a sample of 107 case managers. EESMI items tap individual and social systems factors related to employment for people with psychiatric disabilities. Construct validity was assessed by relationships between EESMI scores and scores on measures of general expectations and opinions of people with serious mental illness, case manager burnout, and social desirability. EESMI consists of three empirically derived subscales with good internal consistency. Case managers' scores on EESMI correlated positively with scores on general expectations and opinions about people with mental illness scales and were generally unrelated to social desirability scores. EESMI scores were positively related to case managers' perceptions of the employability of consumers on their caseloads. EESMI is a psychometrically sound measure of mental health professionals' employment-related expectations of consumers. Reliable and valid assessment is basic to the study of mental health professionals' role in increasing employment opportunities for people with psychiatric disabilities. Study limitations and directions for future research are discussed.

Primary prevention of natural rubber latex allergy in the German health care system through education and intervention.

Allmers, Henning; Schmengler, Jörg; Skudlik, Christoph

2002-08-01

The development of occupational asthma and allergic skin reactions caused by natural rubber latex (NRL) allergy are risks for health care workers. There are few published studies to suggest that intervention programs to reduce exposure will lead to primary prevention of sensitization. This study assesses the effects of intervention to reduce the incidence of NRL allergy in personnel working in health care facilities insured by the German statutory accident insurance company for health care workers, Berufsgenossenschaft für Gesundheitsdienst und Wohlfahrtspflege, with approximately 3 million insured employees, by switching to powder-free NRL gloves. The timing of introduction of intervention strategies, such as education of both physicians and administrators, together with regulations demanding that health care facilities only purchase low-protein, powder-free NRL gloves are reported. We reviewed the annual numbers of reported suspected cases of NRL-caused occupational allergies and the amount and type of gloves used in German acute-care hospitals since 1986. The purchase of powder-free NRL examination gloves exceeded that of powdered gloves for the first time in 1998. This only became true for powder-free NRL sterile gloves 2 years later in 2000. The incidence of suspected occupational NRL allergy cases rose until 1998 and has declined steadily since. There was a 2-year lag between the beginning of the decline in the purchase of powdered NRL examination gloves and the beginning of a decline in suspected NRL-caused occupational asthma cases. Despite the effect of increased recognition of NRL allergies, education about NRL allergies in health care facilities combined with the introduction of powder-free gloves with reduced protein levels has been associated with a decline in the number of suspected cases of occupational allergies caused by NRL in Germany on a nationwide scale. These results clearly indicate that primary prevention of occupational NRL allergies can be achieved if these straightforward and practical interventions are properly carried out and maintained.

Fracture following lower limb lengthening in children: a series of 58 patients.

2013-02-01

Fracture is one of the main complications following external fixator removal used in cases of progressive lower limb lengthening; rates as high as 50% are found in the literature. The aim of this study was to determine the factors influencing this complication. One hundred and eleven cases of lower limb lengthening were performed in 58 patients (40 femurs and 71 tibias). The mean age at surgery was 10.1years old. Lengthening was performed in all cases with an external fixator alone, associated in 39.6% of cases with intramedullary nailing. The patients were divided into three groups according to disease etiology (congenital, achondroplasia and other). The fractures were classified according to the Simpson classification. Twenty fractures were recorded (18%). Sixteen fractures were found in patients with congenital disease, four with achondroplasia and none in the group of other etiologies. The fracture was more often in the femur (27.5%) than in the tibia (12.7%). The rate of fracture is influenced by different factors depending on the etiology of disease. In congenital diseases, the fracture rate is higher when there is lengthening of more than 15% of the initial length and a delay between surgery and the beginning of lengthening of less than 7days. In patients with achondroplasia, the influence of a relative percentage of lengthening is less important than in those with congenital disease. However, to avoid fractures, lengthening should not be started in children under the age of nine. Moreover, lengthening should begin at least 7days after the fixator has been placed. Retrospective.

Sudden cardiac arrest (SCA) is the leading cause of death in athletes during exercise. The effectiveness of school-based automated external defibrillator (AED) programmes has not been established through a prospective study. A total of 2149 high schools participated in a prospective observational study beginning 1 August 2009, through 31 July 2011. Schools were contacted quarterly and reported all cases of SCA. Of these 95% of schools confirmed their participation for the entire 2-year study period. Cases of SCA were reviewed to confirm the details of the resuscitation. The primary outcome was survival to hospital discharge. School-based AED programmes were present in 87% of participating schools and in all but one of the schools reporting a case of SCA. Fifty nine cases of SCA were confirmed during the study period including 26 (44%) cases in students and 33 (56%) in adults; 39 (66%) cases occurred at an athletic facility during training or competition; 55 (93%) cases were witnessed and 54 (92%) received prompt cardiopulmonary resuscitation. A defibrillator was applied in 50 (85%) cases and a shock delivered onsite in 39 (66%). Overall, 42 of 59 (71%) SCA victims survived to hospital discharge, including 22 of 26 (85%) students and 20 of 33 (61%) adults. Of 18 student-athletes 16 (89%) and 8 of 9 (89%) adults who arrested during physical activity survived to hospital discharge. High school AED programmes demonstrate a high survival rate for students and adults who suffer SCA on school campus. School-based AED programmes are strongly encouraged.

Therapeutic Assessment of Complex Trauma: A Single-Case Time-Series Study.

The cumulative effect of repeated traumatic experiences in early childhood incrementally increases the risk of adjustment problems later in life. Surviving traumatic environments can lead to the development of an interrelated constellation of emotional and interpersonal symptoms termed complex posttraumatic stress disorder (CPTSD). Effective treatment of trauma begins with a multimethod psychological assessment and requires the use of several evidence-based therapeutic processes, including establishing a safe therapeutic environment, reprocessing the trauma, constructing a new narrative, and managing emotional dysregulation. Therapeutic Assessment (TA) is a semistructured, brief intervention that uses psychological testing to promote positive change. The case study of Kelly, a middle-aged woman with a history of repeated interpersonal trauma, illustrates delivery of the TA model for CPTSD. Results of this single-case time-series experiment indicate statistically significant symptom improvement as a result of participating in TA. We discuss the implications of these findings for assessing and treating trauma-related concerns, such as CPTSD.

The parent-child-therapist alliance: A case study using a strategic approach.

PubMed

Naidu, Thirusha; Behari, Sheethal

2010-06-01

In this paper we present a single case study of a clinical approach that addresses the needs of parents and their children in psychotherapy. The approach begins by addressing the child's and parent's concerns separately at first by establishing strong therapeutic alliances with each, and then proceeds to address the concerns of the parent-child dyad. The basic premise is that the therapeutic alliance is the central element to successful outcomes in psychotherapy. The nature of alliance-building and its associated methods and techniques have been extensively considered for adult therapy. However, there is considerably less written on the therapeutic alliance with children and adolescents in the context of family interventions. We briefly examine some theoretical dimensions and applications of the therapeutic alliance in psychotherapy with children/adolescents and their parents. A three-phase alliance-building psychotherapy strategy, founded on the idea that each therapeutic relationship warrants an effective working alliance, is proposed. The case of a single mother and her adolescent daughter is employed to illustrate the strategy.

Biomedical conflicts of interest: a defence of the sequestration thesis-learning from the cases of Nancy Olivieri and David Healy.

PubMed

Schafer, A

2004-02-01

No discussion of academic freedom, research integrity, and patient safety could begin with a more disquieting pair of case studies than those of Nancy Olivieri and David Healy. The cumulative impact of the Olivieri and Healy affairs has caused serious self examination within the biomedical research community. The first part of the essay analyses these recent academic scandals. The two case studies are then placed in their historical context-that context being the transformation of the norms of science through increasingly close ties between research universities and the corporate world. After a literature survey of the ways in which corporate sponsorship has biased the results of clinical drug trials, two different strategies to mitigate this problem are identified and assessed: a regulatory approach, which focuses on managing risks associated with industry funding of university research, and a more radical approach, the sequestration thesis, which counsels the outright elimination of corporate sponsorship. The reformist approach is criticised and the radical approach defended.

The prognosis of HIV infection has improved dramatically since the introduction of highly active antiretroviral therapy (HAART). However, numerous adverse effects and limitations regarding tolerability remain a concern. Lipomastia (pseudogynecomastia), a breast enlargement due to central adiposity, may occur as part of a fat redistribution syndrome which has been associated with HAART regimens and several pathogenic mechanisms have been advocated in its development. Here we report an observational longitudinal study of five patients diagnosed of gynecomastia associated with efavirenz-based HAART regimens. All cases reached successful immunologic and virologic responses to HAART. The delay of appearance of gynecomastia from the beginning of HAART ranged between 4 to 15 months. In all five cases, gynecomastia regressed after efavirenz withdrawal (mean period of 5 months). In summary, we think that HAART induced gynecomastia should be suspected in HIV patients receiving efavirenz-containing regimens. Although pathogenesis is unclear, this study and a review of the English literature implicates two possible mechanisms: (a) immune restoration processes and (b) efavirenz mediated estradiol-like effects.

A pregnant adolescent's vulnerability increases when she is a victim of intrafamilial violence and drug addiction, which cause physical and biopsychosocial damage to the mother and her baby. Objective Present and analyze the case of an adolescent who is addicted to drugs, pregnant and the victim of lifelong intrafamilial violence. Method A case study based on a semi-structured interview conducted in the Obstetrics Emergency Unit at the Teaching Hospital of the University of São Paulo. The data were interpreted and analyzed using Content Analysis. Results intrafamilial violence experienced at the beginning of the adolescent's early relationships seriously affected her emotional maturity, triggering the development of psychopathologies and leaving her more susceptible to the use and abuse of alcohol and other drugs. The adolescent is repeating her history with her daughter, reproducing the cycle of violence. Conclusion Adolescent pregnancy combined with intrafamilial violence and drug addiction and multiplies the adolescent's psychosocial vulnerability increased the adolescent's vulnerability.

A case-control study was undertaken to clarify reasons for a four-fold increased incidence of mesothelioma discovered among white males in coastal Tidewater, Va., from 1972 to 1978. Sixty-one cases were identified. Interviews with next of kin revealed that the excess was linked to employment in area shipyards. Three-fourths of the cases had been employed in the shipbuilding industry, nearly all beginning employment prior to 1950. Most were career employees, but an increased risk was also found among those who worked only temporarily, mainly during World War II, and were reportedly exposed to asbestos. More of the cases than controls were pipecoverers or pipefitters, but cases were reported to work in a variety of shipyard trades. Few of the mesothelioma cases were heavy smokers, a trend that may be related in part to the competing risks for fatal diseases caused by the interactions of smoking and asbestos exposure. Information obtained by interview for five of the six white females diagnosed with mesothelioma revealed that the husband of four had been employed in the shipbuilding industry.

Irreversible profound symptomatic bradycardia requiring pacemaker after tizanidine/loxoprofen combination therapy: a case report.

A 37-year-old man suffered irreversible profound symptomatic bradycardia requiring a pacemaker 3 days after beginning tizanidine/loxoprofen combination therapy for neck pain. This combination therapy is prescribed frequently for joint pain; however, combining loxoprofen with tizanidine could increase the risk of symptomatic bradycardia that is both permanent and severe. Similar cases have not been reported. This case suggests that tizanidine should be used cautiously when combined with loxoprofen, and drug interaction screening should be performed.

Health Impact Assessment for Second-Hand Smoke Exposure in Germany--Quantifying Estimates for Ischaemic Heart Diseases, COPD, and Stroke.

PubMed

Fischer, Florian; Kraemer, Alexander

2016-02-05

Evidence of the adverse health effects attributable to second-hand smoke (SHS) exposure is available. This study aims to quantify the impact of SHS exposure on ischaemic heart diseases (IHD), chronic obstructive pulmonary diseases (COPD), and stroke in Germany. Therefore, this study estimated and forecasted the morbidity for the three outcomes in the German population. Furthermore, a health impact assessment was performed using DYNAMO-HIA, which is a generic software tool applying a Markov model. Overall 687,254 IHD cases, 231,973 COPD cases, and 288,015 stroke cases were estimated to be attributable to SHS exposure in Germany for 2014. Under the assumption that the population prevalence of these diseases and the prevalence of SHS exposure remain constant, the total number of cases will increase due to demographic aging. Assuming a total eradication of SHS exposure beginning in 2014 leads to an estimated reduction of 50% in cases, compared to the reference scenario in 2040 for all three diseases. The results highlight the relevance of SHS exposure because it affects several chronic disease conditions and has a major impact on the population's health. Therefore, public health campaigns to protect non-smokers are urgently needed.

Clinical case report. Symptoms in the face and jaw are common after whiplash. Few studies have reported cervicogenic headache in a trigeminal nerve distribution, and no published studies could be found describing such symptoms experienced bilaterally after whiplash. The objective of the current case report was to detail the clinical reasoning and management of an uncommon patient presentation. The 41-year-old female patient of the current case complained of shooting pain in the jaw, cheek and forehead beginning 7 days after her accident. No imaging was performed, and examination ruled out serious pathology. The patient was treated primarily with deep neck flexor (DNF) and proprioceptive training for 10 visits over an 8-week period. The Numeric Pain Rating Scale improved from 2/10 to 0/10, the Neck Disability Index improved from 17/50 to 1/50, and the Neck Flexor Muscle Endurance Test improved from 13 to 30 s. The patient remained symptom-free at 4-month follow-up. The current case report describes a patient presentation unique to the literature. Significant changes were seen by week 3 with DNF and proprioceptive training. Additional research is required to determine the effectiveness of this intervention in similar presentations.

Scientific progress: Knowledge versus understanding.

PubMed

Dellsén, Finnur

2016-04-01

What is scientific progress? On Alexander Bird's epistemic account of scientific progress, an episode in science is progressive precisely when there is more scientific knowledge at the end of the episode than at the beginning. Using Bird's epistemic account as a foil, this paper develops an alternative understanding-based account on which an episode in science is progressive precisely when scientists grasp how to correctly explain or predict more aspects of the world at the end of the episode than at the beginning. This account is shown to be superior to the epistemic account by examining cases in which knowledge and understanding come apart. In these cases, it is argued that scientific progress matches increases in scientific understanding rather than accumulations of knowledge. In addition, considerations having to do with minimalist idealizations, pragmatic virtues, and epistemic value all favor this understanding-based account over its epistemic counterpart.

Williamson, Erin J; Stricker, Julie M; Irazola, Seri P; Niedzwiecki, Emily

2016-01-01

Over the past 3 decades, significant strides have been made to identify and assist wrongfully convicted individuals in gaining their freedom and transitioning to life after exoneration. However, little is known about the experiences of the original crime victims during this process. The impact of wrongful convictions on victims has not been empirically researched; most of what is known has been provided anecdotally by stakeholders working with victims, and in a few instances, by victims themselves (e.g., Jenkins, 2009; Levey, 2004; Thompson-Cannino, Cotton, & Torneo, 2009). In an effort to begin to fill this gap in knowledge, ICF International conducted in-depth studies of 11 cases to identify the shared experiences and service needs of victims across cases of wrongful conviction.

Gravitational lensing of active galactic nuclei.

PubMed Central

Hewitt, J N

1995-01-01

Most of the known cases of strong gravitational lensing involve multiple imaging of an active galactic nucleus. The properties of lensed active galactic nuclei make them promising systems for astrophysical applications of gravitational lensing; in particular, they show structure on scales of milliseconds of arc to tens of seconds of arc, they are variable, and they are polarized. More than 20 cases of strong gravitational lenses are now known, and about half of them are radio sources. High-resolution radio imaging is making possible the development of well-constrained lens models. Variability studies at radio and optical wavelengths are beginning to yield results of astrophysical interest, such as an independent measure of the distance scale and limits on source sizes.

2014-11-01

Laparoscopic cholecystectomy is a very common minimally invasive surgical procedure that may be improved by autonomous or cooperative assistance support systems. Model-based surgery with a precise definition of distinct procedural tasks (PT) of the operation was implemented and tested to depict and analyze the process of this procedure. Reliability of real-time workflow recognition in laparoscopic cholecystectomy ([Formula: see text] cases) was evaluated by continuous sensor-based data acquisition. Ten PTs were defined including begin/end preparation calots' triangle, clipping/cutting cystic artery and duct, begin/end gallbladder dissection, begin/end hemostasis, gallbladder removal, and end of operation. Data acquisition was achieved with continuous instrument detection, room/table light status, intra-abdominal pressure, table tilt, irrigation/aspiration volume and coagulation/cutting current application. Two independent observers recorded start and endpoint of each step by analysis of the sensor data. The data were cross-checked with laparoscopic video recordings serving as gold standard for PT identification. Bland-Altman analysis revealed for 95% of cases a difference of annotation results within the limits of agreement ranging from [Formula: see text]309 s (PT 7) to +368 s (PT 5). Laparoscopic video and sensor data matched to a greater or lesser extent within the different procedural tasks. In the majority of cases, the observer results exceeded those obtained from the laparoscopic video. Empirical knowledge was required to detect phase transit. A set of sensors used to monitor laparoscopic cholecystectomy procedures was sufficient to enable expert observers to reliably identify each PT. In the future, computer systems may automate the task identification process provided a more robust data inflow is available.

Mitral valve coaptation and its relationship to late diastolic flow: A color Doppler and vector flow map echocardiographic study in normal subjects.

PubMed

Sherrid, Mark V; Kushner, Josef; Yang, Georgiana; Ro, Richard

2017-04-01

Three competing theories about the mechanism of mitral coaptation in normal subjects were evaluated by color Doppler and vector flow mapping (VFM): (1) beginning of ventricular (LV) ejection, (2) "breaking of the jet" of diastolic LV inflow, and (3) returning diastolic vortices impacting the leaflets on their LV surfaces. We analyzed 80 color Doppler frames and 320 VFM measurements. In all 20 normal subjects, coaptation occurred before LV ejection, 78±16 ms before onset. On color Doppler frames the larger anterior, and smaller posterior vortices circle back and, in all cases, strike the ventricular surfaces of the leaflets. On the first closing-begins frame, for the first time, vortex velocity normal to the ventricular surface of the anterior leaflet (AML) is greater than that in the mitral orifice, and the angle of attack of LV vortical flow onto the AML is twice as high as the angle of flow onto the valve in orifice. Thus, at the moment coaptation begins, vortical flow strikes the mitral leaflet with higher velocity, and higher angle of attack than orifice flow, and thus with greater force. According to the "breaking of the jet" theory, one would expect to see de novo LV flow perpendicular to the leaflets beginning after transmitral flow terminates. Instead, the returning continuous LV vortical flow that impacts the valve builds continuously after the P-wave. Late diastolic vortices strike the ventricular surfaces of the mitral leaflets and contribute to valve coaptation, permitted by concomitant decline in transmitral flow. © 2017, Wiley Periodicals, Inc.

Horberry, Tim; Burgess-Limerick, Robin; Fuller, Ruth

2013-01-01

This article describes examples of the application of human factors research and development work to a sustainable minerals industry. It begins by outlining human-related aspects of the minerals industry and the key human factors work previously undertaken in this domain. The focus then switches to sustainability in the minerals industry. Sustainability principles are introduced and illustrations provided of how human factors research and development work fits within such a framework. Three case studies of human factors in the minerals industry research are presented and the sustainability implications in each case study are highlighted. Finally, future trends related to human factors work in a sustainable minerals industry are addressed, in particular the opportunities and possible adverse consequences that increasing deployment of mining automation might bring. Minerals industries are a major global activity with significant sustainability implications. Aspects of sustainability in mining are examined using three case studies. These illustrate the contribution of human factors/ergonomics in reducing risks; developing emergency response management systems; and the value of participatory ergonomics in improving the design of mining equipment.

It is highly recommended to conduct a prophylactic check for any dental problems on patients who suffer from leukaemia before chemotherapy begins. Bacteraemia caused by oral microflora may be very dangerous for patients with haematological malignancies. However, it should be noted that the prophylactic process itself might bring about life-threatening complications if there is only a short interval between dental treatment and the beginning of chemotherapy, or if the dental treatment is too aggressive. We present a case where this prophylactic procedure produced life-threatening complications for a patient with acute myeloid leukaemia.

Music therapy internship supervisors and preinternship students: a comparative analysis of questionnaires.

PubMed

Knight, Andrew J

2008-01-01

The purpose of this study was to compare perceptions of professional competency between preinternship music therapy students and internship supervisors. Preinternship music therapy students and internship supervisors were asked to fill out the Internship Concerns Questionnaire (ICQ-ST, student; ICQ-SU, supervisor). Participants (N = 106) included 85 students at 16 AMTA-approved universities (n = 85), and 21 internship supervisors at active AMTA national roster internship sites (n = 21). Twenty items on the ICQ were rated on a Likert-type scale, and 1 item (Part B) asked the participant to indicate any other concerns not addressed in the ICQ. Music therapy interns and supervisors differed significantly in their mean ratings on 2 of the 20 items: "Communicating with facility staff" (p = .025) and "Maintaining client confidence" (p = .016). In both cases the student interns reported a significantly lower mean level of concern about getting assistance in these areas than did their supervisors. The present study suggests that music therapy educators may better prepare music therapy students for a successful internship by evaluating the perceptual gaps in professional training expectations between students and supervisors prior to the internship. Internship supervisors may also benefit from student's own perceptions of their knowledge and skills upon beginning the internship. Ultimately, the student is responsible for being prepared to begin the process from intern to beginning professional at the start of the internship, and to commit to gaining as much as possible from the combination of academic and clinical experiences available to them.

[Predictors of successful transfer to everyday live of a relaxation method acquired in psychosomatic rehabilitation].

Bernardy, K; Krampen, G; Köllner, V

2008-12-01

The aim of the present study was to identify factors at the beginning and at the end of an inpatient psychosomatic rehabilitation predicting the successful transfer of Progressive Relaxation (PR) according to Jacobson three months after the stay. Eighty patients in a psychosomatic rehabilitation centre were studied in the beginning (T1), at discharge (T2) and three months after discharge (T3). Every patient participated in courses on PR. To evaluate the course, parts of the "Diagnostisches und evaluatives Instrumentarium für Entspannungstraining und Entspannungstherapie" were used. Transfer was defined as successful if patients practised PR at least once a week three months after their stay. Potential predictors were: diagnosis, age, symptoms, previous experiences, and motives at T1 and frequency of practising, adequateness of group size and change of symptoms at T2. Stepwise logistic regression analysis was used to identify predictors. Three months after the course 52,5% of the patients were able to transfer PR successfully into their daily lives. 68,8% of cases had been correctly classified by logistic regression through: participation motive "positive thoughts" (T1) and "frequency of practising PR outside the course" (T2). Intrinsic participation motives and practising independently are significant predictors of long-term transfer of PR. This indicates the necessity of discussing motives at the beginning as well as frequency of practising during the PR course. It would be particularly interesting to know whether specific encouraging of motivation would improve the transfer to everyday life.

Construction of knowledge about teaching practice and educating students from diverse cultures in an online induction program

Bice, Lawrence Raymond

2005-11-01

Beginning teachers in both urban areas and geographically isolated rural areas often do not have access to a mentor teacher of the same content area or grade level in their school or district. This project is a study of learning in the on-line e-Mentoring for Student Success (eMSS) program, which provides induction for science and mathematics teachers in Montana and California. The study centered on a particular segment of eMSS called the Diversity Module. Two examinations were conducted: (1) Analysis of discourse by all participants in the Diversity Module, and (2) case study of five beginning teachers with diverse student populations. Analysis of learning by cases was conducted by examining discourse in the Diversity Module, private on-line discussions with their assigned mentors during a two-year period, and pre and post Diversity Module interviews and interviews of their mentors. Three frameworks were developed to aid understanding of findings: (1) discourse analysis, (2) competencies of multicultural teachers, and, (3) competencies of pedagogical and pedagogical content knowledge. Cases developed their knowledge of teaching along a continuum of needs over two years of participation in the eMSS program. Initial needs expressed by mentees were in areas such as classroom management and general methods of instruction. Cases increased their knowledge in virtually all aspects of pedagogical knowledge, changing their expressed needs to pedagogical content knowledge concerns such as adapting and differentiating instruction for particular content and individual students, and building their repertoire of instructional representations. Through on-line discussion, teachers developed or advanced awareness of student culture and learning characteristics, and adapted their practice to foster a climate of student respect. Findings provided little evidence of adapting instruction for diverse student learning. Teachers who had a strong awareness of their own and their students' cultures advanced their understanding of multicultural teaching competencies further than those who did not. Interview results indicated that learning sometimes takes place in a non-visible manner. Growth in multicultural teaching knowledge, as well as several aspects of pedagogical and pedagogical content knowledge, was clearly evident for participants who posted few messages, but read and actively reflected on thoughts of others.

The Effect of a Collaborative Mentoring Program on Beginning Science Teachers' Inquiry-based Teaching Practice

Nam, Jeonghee; Seung, Eulsun; Go, MunSuk

2013-03-01

This study investigated how a collaborative mentoring program influenced beginning science teachers' inquiry-based teaching and their reflection on practice. The one-year program consisted of five one-on-one mentoring meetings, weekly science education seminars, weekly mentoring group discussions, and self-evaluation activities. The participants were three beginning science teachers and three mentors at the middle school level (7-9th grades) in an urban area of South Korea. For each beginning teacher, five lessons were evaluated in terms of lesson design/implementation, procedural knowledge, and classroom culture by using the Reformed Teaching Observation Protocol. Five aspects of the beginning teachers' reflections were identified. This study showed that a collaborative mentoring program focusing on inquiry-based science teaching encouraged the beginning teachers to reflect on their own perceptions and teaching practice in terms of inquiry-based science teaching, which led to changes in their teaching practice. This study also highlighted the importance of collaborative interactions between the mentors and the beginning teachers during the mentoring process.

On the computational modeling of the viscosity of colloidal dispersions and its relation with basic molecular interactions

The connection between fundamental interactions acting in molecules in a fluid and macroscopically measured properties, such as the viscosity between colloidal particles coated with polymers, is studied here. The role that hydrodynamic and Brownian forces play in colloidal dispersions is also discussed. It is argued that many-body systems in which all these interactions take place can be accurately solved using computational simulation tools. One of those modern tools is the technique known as dissipative particle dynamics, which incorporates Brownian and hydrodynamic forces, as well as basic conservative interactions. A case study is reported, as an example of the applications of this technique, which consists of the prediction of the viscosity and friction between two opposing parallel surfaces covered with polymer chains, under the influence of a steady flow. This work is intended to serve as an introduction to the subject of colloidal dispersions and computer simulations, for final-year undergraduate students and beginning graduate students who are interested in beginning research in soft matter systems. To that end, a computational code is included that students can use right away to study complex fluids in equilibrium.

The study of these features are of great importance in understanding the reproductive biology of these insects, especially in the case of those considered pests. Dione juno and Agraulis vanillae stand out as the most important pests of passion fruit (Passiflora sp.) crops in Brazil. Therefore, the objective of the present study was to characterize the testes and germ cells of Dione juno and Agraulis vanillae at different life stages, using light microscopy and scanning and transmission electron microscopy, to understand the maturation mechanisms of the male gametes in these species. The study showed that the larvae of both species have a pair of brown kidney-shaped testes, covered by epithelial cells which divide the organ into four follicles. The testes are full of spermatogonia which begin to differentiate in the third larval instar. In the fifth larval instar, spermatozoa can be observed. When they enter the prepupal stage the testes begin a fusion process that is completed in the adult insects, where they present as spherical organs divided into eight follicles, containing all the cells of the germ line. Spermatogenesis occurs centripetally, and in both species, sperm dimorphism is observed, where two different types of spermatozoa are formed, eupyrene (nucleated) and apyrene (anucleate), which differ in morphology and function. Apart from contributing to scientific basic research on the reproductive biology of these insects, the present study provides important data that can aid in research on the physiology, systematics, and control of these species.

To research (or not) that is the question: ethical issues in research when medical care is disrupted by political action: a case study from Eldoret, Kenya

PubMed Central

House, Darlene R; Marete, Irene; Meslin, Eric M

2016-01-01

While considerable attention has been focused on understanding the myriad of ethical analysis in international research in low and middle income countries, new issues always arise that have not been anticipated in guidelines or studied extensively. The disruption of medical care arising as a direct result of political actions, including strikes, postelection violence and related activities, is one such issue that leaves physician-researchers struggling to manage often conflicting professional responsibilities. This paper discusses the ethical conflicts that arise for physician-researchers, particularly when disruption threatens the completion of a study or completion is possible but at the expense of not addressing unmet medical needs of patients. We review three pragmatic strategies and the ethical issues arising from each: not starting research, stopping research that has already started, and continuing research already initiated. We argue that during episodes of medical care disruption, research that has been started can be continued only if the ethical standards imposed at the beginning of the study can continue to be met; however, studies that have been approved but not yet started should not begin until the disruption has ended and ethical standards can again be assured.

Beginning inflation in an inhomogeneous universe

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

East, William E.; Kleban, Matthew; Linde, Andrei

Using numerical solutions of the full Einstein field equations coupled to a scalar inflaton field in 3+1 dimensions, we study the conditions under which a universe that is initially expanding, highly inhomogeneous and dominated by gradient energy can transition to an inflationary period. If the initial scalar field variations are contained within a sufficiently flat region of the inflaton potential, and the universe is spatially flat or open on average, inflation will occur following the dilution of the gradient and kinetic energy due to expansion. This is the case even when the scale of the inhomogeneities is comparable to themore » initial Hubble length, and overdense regions collapse and form black holes, because underdense regions continue expanding, allowing inflation to eventually begin. In conclusion, this establishes that inflation can arise from highly inhomogeneous initial conditions and solve the horizon and flatness problems, at least as long as the variations in the scalar field do not include values that exceed the inflationary plateau.« less

2010-01-01

The purpose of the present analysis was to examine secular trends in school performance indicators in relationship to the implementation of a programme targeting the school food and physical activity environment. Data on available school performance indicators were obtained; retrospective analyses were conducted to assess trends in indicators in association with programme implementation; each outcome was regressed v. year, beginning with the year prior to programme implementation. The Healthy Kids, Smart Kids programme, a grass-roots effort to enhance the school food and physical activity environment in the Browns Mill Elementary School in Georgia. Data included publicly available school records from the years 1995 to 2006. The number of nurse, counselling and disciplinary referrals per 100 students demonstrated a downward trend, while standardized test scores demonstrated an upward trend beginning in the year of programme implementation. School year was a significant predictor of all indicators. Promoting nutrition and physical activity within the school environment may be a promising approach for enhancing both student health and educational outcomes.

The long story of mitochondrial DNA and respiratory complex I.

PubMed

Degli Esposti, Mauro

2017-01-01

This article examines the long story of the relationship between mitochondrial DNA (mtDNA) and respiratory complex I, NADH:Ubiquinone Oxidoreductase, from its beginning  in the genome of the bacterial endosymbiont which then evolved into the mitochondria of our cells. The story begins with the evolution of ancient forms of bacterial complex I into the Nuo14 complex I that was present in the alpha proteobacterial ancestor of mitochondria. The story then becomes complicated in the diversity of eukaryotic organisms that are currently recognized. Therefore, it does not have a clear end, because currently available information shows different situations of metabolic adaptation and gene loss, indicating cases of de-evolution of the original protonmotive complex into a system that may fundamentally assist [FeFe]-hydrogenases in re-oxidising metabolically produced NADH under anaerobic conditions. The history of complex I is thus a never ending story of molecular and physiological evolution producing new perspectives for studying the enzyme complex that occupies the largest proportion of mitochondrial DNA.

[Wood transformation in dead-standing trees in the forest-tundra of Central Siberia].

2009-01-01

Changes in the composition of wood organic matter in dead-standing spruce and larch trees depending on the period after their death have been studied in the north of Central Siberia. The period after tree death has been estimated by means of cross-dating. The results show that changes in the composition of wood organic matter in 63% of cases are contingent on tree species. Wood decomposition in dead-standing trees is accompanied by an increase in the contents of alkali-soluble organic compounds. Lignin oxidation in larch begins approximately 80 years after tree death, whereas its transformation in spruce begins not earlier than after 100 years. In the forest-tundra of Central Siberia, the rate of wood organic matter transformation in dead-standing trees is one to two orders of magnitude lower than in fallen wood, which accounts for their role as a long-term store of carbon and mineral elements in these ecosystems.

What the comprehensive economics of blindness and visual impairment can help us understand

Frick, Kevin D

2012-01-01

Since the year 2000, the amount written about the economics of blindness and visual impairment has increased substantially. In some cases, the studies listed under this heading are calculations of the costs related to vision impairment and blindness at a national or global level; in other cases the studies examine the cost-effectiveness of strategies to prevent or modify visual impairment or blindness that are intended to be applied as a guide to treatment recommendations and coverage decisions. In each case the references are just examples of many that could be cited. These important studies have helped advocates, policy makers, practitioners, educators, and others interested in eye and vision health to understand the magnitude of the impact that visual impairment and blindness have on the world, regions, nations, and individuals and the tradeoffs that need to be made to limit the impact. However, these studies only begin to tap into the insights that economic logic might offer to those interested in this field. This paper presents multiple case studies that demonstrate that the economics of blindness and visual impairment encompasses much more than simply measures of the burden of the condition. Case studies demonstrating the usefulness of economic insight include analysis of the prevention of conditions that lead to impairment, decisions about refractive error and presbyopia, decisions about disease and injury treatment, decisions about behavior among those with uncorrectable impairment, and decisions about how to regulate the market all have important economic inputs.

The interaction of cells in a tissue depends on the nature of the extracellular matrix. The electrical properties of the narrow extracellular space are unknown. Here we consider cell adhesion mediated by extracellular matrix protein on a solid substrate as a model system. We culture human embryonic kidney (HEK293) cells on silica coated with fibronectin and determine the electrical resistivity in the cell-solid junction \\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\setlength{\\oddsidemargin}{-69pt} \\begin{document} \\begin{equation*}{\\rho}_{{\\mathrm{J}}}=r_{{\\mathrm{J}}}d_{{\\mathrm{J}}}\\end{equation*}\\end{document} by combining measurements of the sheet resistance \\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\setlength{\\oddsidemargin}{-69pt} \\begin{document} \\begin{equation*}r_{{\\mathrm{J}}}\\end{equation*}\\end{document} and of the distance \\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\setlength{\\oddsidemargin}{-69pt} \\begin{document} \\begin{equation*}d_{{\\mathrm{J}}}\\end{equation*}\\end{document} between membrane and substrate. The sheet resistance is obtained from phase fluorometry of the voltage-sensitive dye ANNINE-5 by alternating-current stimulation from the substrate.

We change the resistivity of the bath in a range from \\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\setlength{\\oddsidemargin}{-69pt} \\begin{document} \\begin{equation*}66\\hspace{.167em}{\\Omega}\\hspace{.167em}{\\mathrm{cm}}\\end{equation*}\\end{document} to \\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\setlength{\\oddsidemargin}{-69pt} \\begin{document} \\begin{equation*}750\\hspace{.167em}{\\Omega}\\hspace{.167em}{\\mathrm{cm}}\\end{equation*}\\end{document} and find that the sheet resistance \\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\setlength{\\oddsidemargin}{-69pt} \\begin{document} \\begin{equation*}r_{{\\mathrm{J}}}\\end{equation*}\\end{document} is proportionally enhanced, but that the distance is invariant around \\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\setlength{\\oddsidemargin}{-69pt} \\begin{document} \\begin{equation*}d_{{\\mathrm{J}}}=75\\hspace{.167em}{\\mathrm{nm}}\\end{equation*}\\end{document}.

A similar result is obtained for rat neurons cultured on polylysine. On that basis, we propose a “bulk resistivity in cell adhesion” model for cell-solid junctions. The observations suggest that the electrical interaction between cells in a tissue is determined by an extracellular space with the electrical properties of bulk electrolyte. PMID:16399830

There is much literature on crisis support in schools but little on how school staff are affected. This research had two aims: to begin to explore the coping strategies used by school staff after a crisis event, and to investigate measures that might prove valuable for future research. Seven cases are presented using three measures: the WHO (Five) Wellbeing Index, the Impact of Event Scale–Revised, and the Ways of Coping–Revised. Results from this initial study show great variation in the range of responses reported by teachers. PMID:25170309

Conceptual frameworks, geomorphic interpretation and storytelling: Tales from Lockyer Creek , Australia.

NASA Astrophysics Data System (ADS)

Croke, Jacky; Phillips, Jonathan; Van Dyke, Chris

2017-04-01

Earth science knowledge and insight begins with case studies, and theories should be derived from and ultimately evaluated against empirical, case study evidence. However, isolated case studies not linked conceptually to other locations or embedded within a broader framework are often of limited use beyond the study site. Geomorphic evidence and phenomena may be interpreted using a variety of conceptual frameworks (theories, models, laws, methodologies, etc.). The evidence may be, or at least appear to be, consistent with multiple frameworks, even when those constructs are derived from entirely different assumptions or frames of reference. Thus different interpretations and stories can be derived from the same evidence. Our purpose here is to illustrate this phenomenon via a case study from Lockyer Creek, southeast Queensland, Australia. Lockyer Creek is fast becoming one of Australia's most studied catchments with a wealth of data emerging following two extreme flood events in 2011 and 2013. Whilst the initial objective of the Big Flood project was to provide information on the frequency and magnitude of these extreme events, in essence the project revealed a rich 'story' of river evolution and adjustment which at first glance did not appear to 'fit' many established conceptual frameworks and theories. This presentation tells the tale of Lockyer Creek as it relates to selected key conceptual frameworks and importantly how this information can then be used for more effective catchment and flood management.

The Nurse in the University: A History of University Education for South African Nurses: A Case Study of the University of the Witwatersrand

PubMed Central

Horwitz, Simonne

2011-01-01

This paper charts the history and debates surrounding the introduction of academic, university-based training of nurses in South Africa. This was a process that was drawn out over five decades, beginning in the late 1930s. For nurses, university training was an important part of a process of professionalization; however, for other members of the medical community, nursing was seen as being linked to women's service work. Using the case-study of the University of the Witwatersrand, one of South Africa's premier universities and the place in the country to offer a university-based nursing program, we argue that an historical understanding of the ways in which nursing education was integrated into the university system tells us a great deal about the professionalization of nursing. This paper also recognises, for the first time, the pioneers of this important process. PMID:21994840

Overcoming obstacles to behavior change in diabetes self-management.

2003-01-01

This study describes how 5 individuals with type 2 diabetes overcame obstacles that interfered with maintaining behavior changes in diet, exercise, and self-monitoring of blood glucose (SMBG). In-depth interviews provided the framework for this descriptive study. During audiotaped, face-to-face, follow-up structured and unstructured interviews, the participants shared their experiences about obstacles encountered and strategies used to overcome them. Each case was examined independently, and all cases were then compared with each other. Obstacles that interfered with maintaining a diet plan were hunger, planned and unplanned meal events, and the desire for new foods. Physical illness and unexpected life events were obstacles to maintaining an exercise and SMBG plan. Health professionals who assist patients who are beginning behavior change or having difficult maintaining changes need to have an understanding of the various obstacles and how patients can maintain behavior changes over time.

Upon the reconstruction of accidents triggered by tire explosion. Analytical model and case study

NASA Astrophysics Data System (ADS)

Gaiginschi, L.; Agape, I.; Talif, S.

2017-10-01

Accident Reconstruction is important in the general context of increasing road traffic safety. In the casuistry of traffic accidents, those caused by tire explosions are critical under the severity of consequences, because they are usually happening at high speeds. Consequently, the knowledge of the running speed of the vehicle involved at the time of the tire explosion is essential to elucidate the circumstances of the accident. The paper presents an analytical model for the kinematics of a vehicle which, after the explosion of one of its tires, begins to skid, overturns and rolls. The model consists of two concurent approaches built as applications of the momentum conservation and energy conservation principles, and allows determination of the initial speed of the vehicle involved, by running backwards the sequences of the road event. The authors also aimed to both validate the two distinct analytical approaches by calibrating the calculation algorithms on a case study

A mathematical model of case-ascertainment bias: Applied to case-control studies nested within a randomized screening trial.

PubMed

Jansen, Rick J; Alexander, Bruce H; Hayes, Richard B; Miller, Anthony B; Wacholder, Sholom; Church, Timothy R

2018-01-01

When some individuals are screen-detected before the beginning of the study, but otherwise would have been diagnosed symptomatically during the study, this results in different case-ascertainment probabilities among screened and unscreened participants, referred to here as lead-time-biased case-ascertainment (LTBCA). In fact, this issue can arise even in risk-factor studies nested within a randomized screening trial; even though the screening intervention is randomly allocated to trial arms, there is no randomization to potential risk-factors and uptake of screening can differ by risk-factor strata. Under the assumptions that neither screening nor the risk factor affects underlying incidence and no other forms of bias operate, we simulate and compare the underlying cumulative incidence and that observed in the study due to LTBCA. The example used will be constructed from the randomized Prostate, Lung, Colorectal, and Ovarian cancer screening trial. The derived mathematical model is applied to simulating two nested studies to evaluate the potential for screening bias in observational lung cancer studies. Because of differential screening under plausible assumptions about preclinical incidence and duration, the simulations presented here show that LTBCA due to chest x-ray screening can significantly increase the estimated risk of lung cancer due to smoking by 1% and 50%. Traditional adjustment methods cannot account for this bias, as the influence screening has on observational study estimates involves events outside of the study observation window (enrollment and follow-up) that change eligibility for potential participants, thus biasing case ascertainment.

Cardiopulmonary resuscitation quality: Widespread variation in data intervals used for analysis.

Talikowska, Milena; Tohira, Hideo; Bailey, Paul; Finn, Judith

2016-05-01

There is a growing body of evidence for the relationship between CPR quality and survival in cardiac arrest patients. We sought to describe the characteristics of the analysis intervals used across studies. Relevant papers were selected as described in our recent systematic review. From these papers we collected information about (1) the time interval used for analysis; (2) the event that marked the beginning of the analysis interval; and (3) the minimum amount of CPR quality data required for a case to be included in the analysed cohort. We then compared this data across papers. Twenty-one studies reported on the association between CPR quality and cardiac arrest patient survival. In two thirds of studies data from the start of the resuscitation episode was analysed, in particular the first 5min. Commencement of the analysis interval was marked by various events including ECG pad placement and first chest compression. Nine studies specified a minimum amount of data that had to have been collected for the individual case to be included in the analysis; most commonly 1min of data. The use of shorter intervals allowed for inclusion of more cases as it included cases that did not have a complete dataset. To facilitate comparisons across studies, a standardised definition of the data analysis interval should be developed; one that maximises the amount of cases available without compromising the data's representability of the resuscitation effort.

2017-02-01

Effective breast cancer treatment requires the assessment of metabolic changes of tumor tissue during chemo- and hormonotherapy for prediction tumor response. Evaluation of the dynamics of tumor oxygen state (by diffuse optical spectroscopy imaging) and tumor vasculature (by ultrasound investigation in power Doppler mode) was performed before treatment beginning and before the second cycle of chemotherapy in 16 patients who received preoperative chemotherapy. Changes of these indicators were compared then with tumor pathologic response. Breast tumors demonstrated different dynamics of tumor oxygenation depending on the changes of tumor tissue. The increase of the tumor oxygenation after the first cycle of chemotherapy was observed in five of six patients with grade 4 and 5 of pathologic tumor response. Decrease of the oxygenation level was revealed in one patient with the 4th degree of tumor response. Variable changes of the oxygenation level were mentioned in the patients with moderate (the 3d degree) tumor response. Tumor oxygenation decreased or was unchanged in case of 1 or 2 degree of tumor response in five of six cases. The study of the tumor blood vessels didn't reveal any correlation between vasculature changes and tumor response under the performed treatment. The trend of tumor oxygenation in early time after treatment beginning might be a predictive criterion of tumor sensitivity to chemotherapy.

Measurement of rheologic property of blood by a falling-ball blood viscometer.

PubMed

Eguchi, Yoko; Karino, Takeshi

2008-04-01

The viscosity of blood obtained by using a rotational viscometer decreases with the time elapsed from the beginning of measurement until it reaches a constant value determined by the magnitude of shear rate. It is not possible to obtain an initial value of viscosity at time t = 0 that is considered to exhibit an intrinsic property of the fluid by this method. Therefore, we devised a new method by which one can obtain the viscosity of various fluids that are not affected by both the time elapsed from the beginning of measurement and the magnitude of shear rate by considering the balance of the forces acting on a solid spherical particle freely falling in a quiescent viscous fluid. By using the new method, we studied the rheologic behavior of corn syrups, carboxy-methyl cellulose, and human blood; and compared the results with those obtained with a cone-and-plate viscometer. It was found that in the case of corn syrups and washed red cell suspensions in which no red cell aggregate (rouleau) was formed, the viscosity obtained with the two different methods were almost the same. In contrast to this, in the case of the whole blood in which massive aggregates were formed, the viscosity obtained with a falling-ball viscometer was much larger than that obtained with a cone-plate viscometer.

Rotation therapy for maniacs, melancholics and idiots: theory, practice and perception in European medical and literary case histories.

Dickson, Sheila

2018-03-01

This article examines the development and use of rotation therapy in the emerging field of psychiatry at the beginning of the 19th century, and the cross-fertilization between British, Irish, German, French and other European proponents of 'Cox's Swing'. Its short-lived popularity is linked to prevalent Enlightenment thought, to the development of an industrial and technological society, to the modern medical theories of irritability, and to the new practice of 'moral management' of the mentally ill. Case studies documenting the use of the Swing are considered from these perspectives, and are compared with contemporary public reactions in the form of publications in newspapers and of a literary text by German Romantic author Ludwig Achim von Arnim.

We report a retrospective monocentric descriptive study performed in CHI Creteil for 20 months to describe the management and outcome of amikacin monotherapy as an alternative to third-generation cephalosporins for empiric treatment of febrile urinary tract infection (FUTI) in children. Data were analyzed for 151 children, and 90 selected cases were classified as certain or highly probable FUTI. Escherichia coli infection was found in 89 cases. In all patients, fever was resolved within 72 hours after beginning amikacin treatment. Only 5.3% of children were febrile after 48 hours. The mean amikacin treatment duration was 3.05 ± 0.13 days before oral treatment began (guided by antibiotic susceptibility testing). Amikacin monotherapy seems effective for the initial management of FUTI in children.

Twentieth-century astronomical heritage: the case of the Brazilian National Observatory

NASA Astrophysics Data System (ADS)

Barboza, Christina Helena

2016-10-01

This paper aims at contributing to the UNESCO-IAU Astronomy and World Heritage Initiative's discussions by presenting the case study of a 20th-century observatory located in a South American country. In fact, the National Observatory of Brazil was created in the beginning of the 19th century, but its present facilities were inaugurated in 1921. Through this paper a brief description of the heritage associated with the Brazilian observatory is given, focused on its main historical instruments and the scientific and social roles it performed along its history. By way of conclusion, the paper suggests that the creation of the Museum of Astronomy and Related Sciences with its multidisciplinary team of academic specialists and technicians was decisive for the preservation of that expressive astronomical heritage.

The TMT Detailed Science Case describes the transformational science that the Thirty Meter Telescope will enable. Planned to begin science operations in 2024, TMT will open up opportunities for revolutionary discoveries in essentially every field of astronomy, astrophysics and cosmology, seeing much fainter objects much more clearly than existing telescopes. Per this capability, TMT's science agenda fills all of space and time, from nearby comets and asteroids, to exoplanets, to the most distant galaxies, and all the way back to the very first sources of light in the universe. More than 150 astronomers from within the TMT partnership and beyond offered input in compiling the new 2015 Detailed Science Case. The contributing astronomers represent the entire TMT partnership, including the California Institute of Technology (Caltech), the Indian Institute of Astrophysics (IIA), the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC), the National Astronomical Observatory of Japan (NAOJ), the University of California, the Association of Canadian Universities for Research in Astronomy (ACURA) and US associate partner, the Association of Universities for Research in Astronomy (AURA).

This study aimed to test the feasibility of using a mobile device (Apple technology: iPodTouch®, iPhone® or iPad®) among people with severe mental illness (SMI) in a rehabilitation and recovery process and to document the parameters to be taken into account and the issues involved in implementing this technology in living environments and mental health care settings. A qualitative multiple case study design and multiple data sources were used to understand each case in depth. A clinical and comprehensive analysis of 11 cases was conducted with exploratory and descriptive aims (and the beginnings of explanation building). The multiple-case analysis brought out four typical profiles to illustrate the extent of integration of a personal digital assistant (PDA) as a tool to support mental health rehabilitation and recovery. Each profile highlights four categories of variables identified as determining factors in this process: (1) state of health and related difficulties (cognitive or functional); (2) relationship between comfort level with technology, motivation and personal effort deployed; (3) relationship between support required and support received; and (4) the living environment and follow-up context. This study allowed us to consider the contexts and conditions to be put in place for the successful integration of mobile technology in a mental health rehabilitation and recovery process.

Variation in dual-task performance reveals late initiation of speech planning in turn-taking.

PubMed

Sjerps, Matthias J; Meyer, Antje S

2015-03-01

The smooth transitions between turns in natural conversation suggest that speakers often begin to plan their utterances while listening to their interlocutor. The presented study investigates whether this is indeed the case and, if so, when utterance planning begins. Two hypotheses were contrasted: that speakers begin to plan their turn as soon as possible (in our experiments less than a second after the onset of the interlocutor's turn), or that they do so close to the end of the interlocutor's turn. Turn-taking was combined with a finger tapping task to measure variations in cognitive load. We assumed that the onset of speech planning in addition to listening would be accompanied by deterioration in tapping performance. Two picture description experiments were conducted. In both experiments there were three conditions: (1) Tapping and Speaking, where participants tapped a complex pattern while taking over turns from a pre-recorded speaker, (2) Tapping and Listening, where participants carried out the tapping task while overhearing two pre-recorded speakers, and (3) Speaking Only, where participants took over turns as in the Tapping and Speaking condition but without tapping. The experiments differed in the amount of tapping training the participants received at the beginning of the session. In Experiment 2, the participants' eye-movements were recorded in addition to their speech and tapping. Analyses of the participants' tapping performance and eye movements showed that they initiated the cognitively demanding aspects of speech planning only shortly before the end of the turn of the preceding speaker. We argue that this is a smart planning strategy, which may be the speakers' default in many everyday situations. Copyright © 2014 Elsevier B.V. All rights reserved.

The performance of TLS in monitoring periglacial and glacial processes: comprehensive view of case studies in the Austrian Alps.

2009-04-01

Monitoring periglacial and glacial processes is a crucial task in observing the ongoing global warming as a result of climate change in high mountain areas. The project ALPCHANGE - Climate change and impacts in Southern Austrian Alpine Regions (www.alpchange.at) - comprises 4 test sites for terrestrial laserscanning (using Riegl long range laserscanner LPM-2k) such as Pasterze glacier (glacial, beginning in 2001, 8 data sets), Gössnitzkees (glacial, beginning in 2000, 9 data sets), Hinteres Langtalkar (periglacial, beginning in 2000, 9 data sets) and Fallbichl (periglacial, beginning in 2008). In September 2008 an airborne LiDAR (Light detection and ranging) campaign was carried out in all test sites for comparison to terrestrial data. Data acquisition in very remote areas such as Gössnitzkees and Hinteres Langtalkar were affected by partly insufficient power supply due to long acquisition time due to e.g. changing weather conditions. At Pasterze glacier especially meteorological conditions downgraded the quality of acquired data. Wrong distances are partly measured due to varying temperatures in different air packages covering the glacier. Reason for that is a large difference in elevation of appr. 300m from the scanneŕs position to the scanning area as well as an unfavourable scanning angle of 15 - 45°. We used up to 10 reflective traffic signs placed on the glacier surface, independently positioned with DGPS and geodetic surveys, to validate measurement data and correct the digital terrain model (DTM). At all test sites it turned to be crucial that non moving areas such as bedrock are within the scanning sector. Changing conditions (e.g. scanner horizontation, atmospheric influences) always need independent data for orientation and validation.

A longitudinal study of teachers' occupational well-being: Applying the job demands-resources model.

2018-04-01

The job demands-resources model (JD-R model; Bakker & Demerouti, 2014) is well established in occupational research, and the proposed processes it posits have been replicated numerous times. Thus, the JD-R model provides an excellent framework for explaining the occupational well-being of beginning teachers-an occupation associated with particularly high levels of strain and consequently, high attrition rates. However, the model's assumptions have to date mostly been tested piecewise, and seldom on the basis of longitudinal models. With a series of longitudinal autoregressive SEM models (N = 1,700) we tested all assumptions of the JD-R model simultaneously in one model with an applied focus on beginning teachers. We assessed self-reports of beginning teachers at three time waves: at the beginning and end (one and a half to two years later) of their preservice period, and again, one year later. Results revealed significant direct effects of resources (self-efficacy) on engagement, of demands (classroom disturbances) on strain (emotional exhaustion), and a significant reverse path of engagement on self-efficacy. Additionally, the results showed two moderation effects: Self-efficacy buffered the demands-strain relationship, while self-efficacy also predicted engagement, especially when disturbances were high. Thus, self-efficacy in classroom management plays an important role in the teachers' stress development process, as it will, in case of high classroom disturbances, not only buffer the strain-enhancing effects, but also boost engagement. Commitment was predicted directly by emotional exhaustion and engagement, but indirectly only by self-efficacy (via engagement). Thus, we provide strong empirical support for the JD-R model.

Results of ozone measurements in Northern Germany: A case study

NASA Technical Reports Server (NTRS)

Schmidt, Manfred

1994-01-01

At most of the German ozone recording stations which have records over a sufficiently long period, the results of the summer months of 1989 showed the highest values since the beginning of the measurements. One of the reasons for this phenomenon was the high duration of sunshine in that summer; for example, in Potsdam near Berlin in May 1989 the sunshine duration was the highest in May since the beginning of the records in 1893. For that reason we selected this summer for a case study. The basis for the study was mainly the ozone measuring stations of the network of Lower Saxony and the Federal Office of Environment (Umweltbundesamt). The results of these summer measurements point to intense sources of ozone, probably in form of gaseous precursors, in the Middle German industrial areas near Leipzig and Halle and in Northwestern Czechoslovakia, with coal-mining, chemical and petrochemical industries, coking plants and others. The maps of average ozone concentrations, number or days with high ozone maxima, ozone-windroses of the stations, etc., suggest that these areas could be a main source of precursors and of photochemical ozone production in summer smog episodes in Central Europe. Stations on the North Sea coast, at which early ozone measurements were made by our institute in 1973/74 are compared with similarly located stations of the Lower Saxon network in 1989 and the results show a reversal of the ozone-windroses. In 1973/74, the highest ozone concentrations were correlated with wind directions from the sea while in 1989 these concentrations were correlated with directions from the continent. In the recent years, photochemical ozone production on the continent is probably predominant, while in former years the higher ozone content of the maritime subpolar air masses has been explained by stratospheric-tropospheric exchange.

Selective mutism (SM) is a relatively rare childhood disorder and is underdiagnosed and undertreated. The purpose of the retrospective naturalistic study was to examine the long-term outcome of children with SM who were treated with specifically designed modular cognitive behavioral therapy (MCBT). Parents of 36 children who met diagnostic criteria of SM that received MCBT treatment were invited for a follow-up evaluation. Parents were interviewed using structured scales and completed questionnaires regarding the child, including the Selective Mutism Questionnaire (SMQ). Twenty-four subjects were identified and evaluated. Their mean age ± SD of onset of SM symptoms, beginning of treatment, and age at follow-up were 3.4 ± 1.4, 6.4 ± 3.1, and 9.3 ± 3.4 years, respectively. There was robust improvement from beginning of treatment to follow-up evaluation in SM, social anxiety disorder, and specific phobia symptoms. The recovery rate from SM was 84.2 %. SM-focused MCBT is feasible in children and possibly effective in inducing long-term reduction of SM and comorbid anxiety symptoms. • There are limited empirical data on selective mutism (SM) treatment outcome and specifically on cognitive-behavioral therapy, with the majority of studies being uncontrolled case reports of 1 to 2 cases each. • There is also limited data on the long-term outcome of children with SM following treatment. What is New: • Modular cognitive behavioral treatment is a feasible and possibly effective treatment for SM. Intervention at a younger age is more effective comparing to an older age. • Treatment for SM also decreases the rate of psychiatric comorbidities, including separation anxiety disorder and specific phobia.

Timoney, P J; Powell, D G

1982-11-20

Between January 1978 and August 1982 the streptomycin resistant strain of the contagious equine metritis organism (CEMO) was isolated from 15 colts and two fillies in the United Kingdom and Ireland. A first season stallion was also suspected of having initiated an outbreak of contagious equine metritis (CEM) at the beginning of the 1982 breeding season. A detailed investigation of the breeding history of the dams and sires of each positive individual indicated that in a number of cases the CEMO was acquired either in utero or following transmission at the time of parturition. In several other cases the retrospective evidence suggested that the genital tract of colt foals became contaminated with vaginal discharge from mares showing clinical signs of the disease during the nursing period. The findings emphasise the need for a thorough examination of the genital tract of colts and fillies as recommended in the code of practice for the control of CEM when they begin their breeding career.

Schizophrenia is an idiopathic mental disorder with a heritable component and a substantial public health impact. We conducted a multi-stage genome-wide association study (GWAS) for schizophrenia beginning with a Swedish national sample (5,001 cases and 6,243 controls) followed by meta-analysis with previous schizophrenia GWAS (8,832 cases and 12,067 controls) and finally by replication of SNPs in 168 genomic regions in independent samples (7,413 cases, 19,762 controls and 581 parent-offspring trios). We identified 22 loci associated at genome-wide significance; 13 of these are new, and 1 was previously implicated in bipolar disorder. Examination of candidate genes at these loci suggests the involvement of neuronal calcium signaling. We estimate that 8,300 independent, mostly common SNPs (95% credible interval of 6,300-10,200 SNPs) contribute to risk for schizophrenia and that these collectively account for at least 32% of the variance in liability. Common genetic variation has an important role in the etiology of schizophrenia, and larger studies will allow more detailed understanding of this disorder.

Patients with presenting with left-sided FTLD syndromes sometimes develop a new preoccupation with art, greater attention to visual stimuli, and increased visual creativity. We describe the case of a 53-year-old, right-handed man with a history of bipolar disorder who presented with language and behavior impairments characteristic of FTLD, then developed motor symptoms consistent with a second diagnosis of amyotrophic lateral sclerosis. Though the patient had never created visual art before, he developed a compulsion for painting beginning at the earliest stages of his disease, and continued producing art daily until he could no longer lift a paintbrush because of his motor deficits. Upon autopsy, he was found to have ubiquitin and TDP43-positive inclusions with MND pathology. This case study details the patient’s longitudinal neuropsychological, emotional, behavioral, and motor symptoms, along with structural imaging, neurologic, and neuropathologic findings. Multiple examples of the patient’s art are depicted throughout all stages of his illness, and the possible cognitive, behavioral, and neurologic correlates of his new-onset visual artistry are discussed.

Toxic epidemial necrolysis (TEN) is an acute adverse drug reaction, that has an unpredictableprogression and a 30% mortality. The incidence of TEN in the general population is approximately 0.4 to 1.2 cases/million/year. It is characterized pathologically by keratinocyte apoptosis which leads to epidemial detachment. Keratinocyte apoptosis is triggered by activation of the Fas-FasL, pathway and could be prevented by the use of intravenous immunoglobulin (IVIG). To report the experience with the use of IVIG in TEN. Retrospective study of 15 patients with a diagnosis of Stevens-Johnson/TEN overlap (SJS/TEN) or TEN, that received a total dose of 23 +/- 0.6 mg/kg ofIVIG over aperiod of 3 to 4 days. The infusión was initiated during thefirst 24 hours after diagnosis and was associated with standard care for burn victims. Steroids were avoided if the patient was not in chronic steroidal therapy. Allpatients responded to IVIG in a lapse of 46.4 +/- 14.2 hours from the beginning of infusión. Eighty percent of patients survived, but one developed acute renal failure due to IVIG, and another became blind due to corneal opacities, a complication of TEN. Those who survived were discharged after a lapse of 19-8 +/- 6.6 days from the beginning ofthe disease. Despite the lack of blind, multicentric and randomized triáis, we agree with some international studies that TVIG is beneficial as a treatment for SSJ/NETand TEN .
