Published: November 2019

Las interfaces cerebro-computadora no invasivas basadas en EEG de imaginación motora (miBCI) prometen restaurar efectivamente el control motor a pacientes con discapacidades motoras, por ejemplo, aquellos con lesión de la médula espinal (LME). Sin embargo, todavía es necesario investigar las miBCI, con fines de rehabilitación, para este tipo de pacientes que utilizan dispositivos de adquisición de señales EEG de bajo costo, tales como Emotiv EPOC. En este trabajo, se describe en detalle y se comparan diez arquitecturas miBCI basadas en información de covarianza de señales EEG, adquiridas con Emotiv EPOC, para la decodificación de intención de mano abierta y cerrada en tres sujetos control y dos pacientes con LME cervical. Cuatro de estas diez miBCI usan información de covarianza para construir filtros espaciales y el resto usa la información covarianza como una representación directa de las señales EEG, permitiendo la manipulación directa mediante geometría de Riemann. Como resultado, se encontró que, a pesar de que todas las arquitecturas miBCI tienen una precisión general por encima del nivel de azar, las que utilizan la covarianza como representación directa de las señales EEG junto con clasificadores lineales, superan las miBCI que usan la covarianza para el filtrado espacial, tanto en sujetos de control como en pacientes con LME. Estos resultados sugieren un alto potencial de las miBCI basadas en la geometría de Riemann para la rehabilitación de pacientes con LME, utilizando dispositivos de adquisición de EEG de bajo costo.

Authors: Ballejos Marlene P. , Shane Nancy , Romero-Leggott Valerie , Sapién Robert E.
Published: November 2019

Background and Objectives: We sought to evaluate whether the University of New Mexico (UNM) Combined Baccalaureate/Medical Degree (BA/MD) program increases the likelihood that students match into family medicine residencies.
Methods: We used binary logistic regression to predict interest and actual residency match in family medicine. We compared BA/MD participants to similar peers (one-to-one match subject design) and all other students for the nine cohorts of medical students who have matriculated into UNM School of Medicine since the inception of the BA/MD program (medical school matriculation years 2009-2017). We also investigated whether BA/MD students were more likely to select family medicine as their specialty choice at the time of matriculation using survey responses.
Results: At the time of matriculation, the differences in identifying family medicine as a first specialty choice between BA/MD, similar peers, and all other students were small and not statistically significant. However, upon graduation, 33% of BA/MD students matched into family medicine compared to 17% of similar peers, a statistically significant difference even after controlling for United States Medical Licensing Examination (USMLE) test scores and several demographic factors.
Conclusions: The University of New Mexico Combined Baccalaureate/Medical Degree students match into family medicine at nearly twice the rate of traditional medical degree students, suggesting that the UNM BA/MD program serves to increase the growth rate of the family medicine workforce.

Authors: Namak Shahla Y. , Vejnović Aleksandra , Vejnović Tihomir R. , Moore Justin B. , Kirk Julienne K.
Published: November 2019

Background and Objectives: The Advanced Life Support in Obstetrics (ALSO) course is widely utilized in the United States as an evidence-based program that bridges knowledge gaps and improves skills via hands-on training, group learning, and memorization of standardized mnemonics in a team-based approach to patient care. This reduces communication barriers among maternity care providers, ultimately decreasing potential negative outcomes. A needs assessment identified that Serbian providers would benefit from structured learning and hands-on simulation approaches in obstetrics from a structured training like the ALSO course. The objective of this study was to explore the changes in clinicians’ knowledge and preferred scenario responses in managing obstetrics cases before and after participation in the ALSO course.
Methods: The ALSO training lasted 2 days and included lecture sessions, interactive workshops, a written knowledge test, and a simulated skills test. Participants completed an additional 20-item questionnaire assessing their knowledge and preferred scenario responses two weeks pre- and immediately post-ALSO training. Using a paired t test we assessed changes between pre- and posttest knowledge and preferred scenario response scores.
Results: Twenty-seven participants provided complete data. For the entire sample, the pretest mean number of correct items on the knowledge and preferred scenario response assessment was 10.8 and the posttest mean number correct was 15.2, representing an increase of 4.4 correct answers (P<.001).
Conclusions: The current results suggest that the ALSO course can successfully increase knowledge and preferred scenario responses in Serbian providers and may be a viable approach to improving birth outcomes.

Published: November 2019

Background and Objectives: Specialized medical school educational tracks aim to increase the primary care workforce. The International/Inner-City/Rural Preceptorship (I2CRP) Program is unique in addressing multiple communities, a large cohort and applying the Self Determination Theory framework. This study examined program impact by analyzing the numbers of graduates matched into primary care and practicing in medically underserved communities.
Methods: We compared the match list of I2CRP graduates between 2000 and 2017 (n=204) to non-I2CRP Virginia Commonwealth University School of Medicine (VCU SOM) graduates (n=3,037). We analyzed the matches into primary care, National Health Service Corps (NHSC) priority specialties, and NHSC priority plus general surgery. We searched a federal database to determine which graduates are practicing in workforce shortage areas.
Results: Many more I2CRP graduates matched to primary care (71.1%), compared to non-I2CRP graduates (38.2%; P<.001). Within primary care, I2CRP graduates matched to family medicine more frequently than non-I2CRP graduates (36.3% vs 8.4%). Eighteen percent of posttraining I2CRP graduates work in rural areas and 41% work in medically underserved areas.
Conclusions: I2CRP graduates are more likely to match to family medicine and primary care. I2CRP curriculum nurtures new medical students’ interest in primary care, and self-determination theory provides a framework to organize the program curriculum. The program’s impact endures as evidenced by participants’ continued work in underserved areas after residency. Increasing support for such programs may help address the primary care physician shortage in medically underserved areas.

Authors: Starnes Joseph R. , Slesur Lauren , Holby Neil , Rehman Saad , Miller Robert F.
Published: November 2019

Background and Objectives: Missed appointments represent a significant challenge to the efficient and effective provision of care in the outpatient setting. High no-show rates result in ineffective use of human resources and contribute to loss of follow-up. Shade Tree Clinic (STC) is a student-run, comprehensive primary care clinic that serves more than 350 Middle Tennessee residents. This study aimed to use available data to predict no-shows to improve clinic efficiency and service quality.
Methods: Data were pulled from clinic scheduling software for all appointments at STC between January 1, 2010 and December 31, 2015. Weather data were added for each appointment date using an online database. Multivariable logistic regression was used to create models from these historical data.
Results: A total of 13,499 appointments were included with an overall show rate of 69.2%. The final model contained previous show rate (OR 1.063; P<.001), day of the week (OR 1.20; P<.001), automated reminder (OR 1.40; P<.001), snow in inches (OR .33; P<.001), and high ambient temperature in degrees (OR 1.01; P<.001). Using a cutoff probability of the 25th percentile, the model had a negative predictive value of 61.0%.
Conclusions: Based on readily available data and a novel conceptual framework, we can identify the quarter of patients least likely to present for scheduled appointments and target them for interventions, allowing care providers to more effectively address community health care disparities through the clinic. This analysis is replicable at any clinic using an electronic medical record.

Authors: Sanchez Amy , Farahi Narges , Flower Kori B. , Page Cristen P.
Published: November 2019

Background and Objectives: Despite the importance of breastfeeding, most US women do not meet recommendations for length of any or exclusive breastfeeding. Support in primary care settings is recommended (US Preventive Services Task Force, 2016), but optimal implementation strategies are not established. We evaluated the effect on breastfeeding rates of on-site breastfeeding support within an academic family medicine center with a diverse patient population.
Methods: We conducted a retrospective chart review 10 months before and 10 months following the implementation of integrated breastfeeding support provided by an International Board Certified Lactation Consultant (IBCLC) or MD-IBCLC. Two hundred eighty-one infants were identified, 140 before implementation and 141 after. A research assistant extracted data from the electronic medical record. We performed bivariate and multiple logistic regression analyses using STATA.
Results: There were no significant demographic differences before and after the intervention. The proportion of infants with any breastfeeding at 2, 4, and 6 months was greater in the postimplementation group (71.7% vs 86.7% at 2 months, P=.05; 61.5% vs 77.1% at 4 months, P=.08; and 50.7% vs 64.4%, P=.09 at 6 months). The proportion of infants exclusively breastfed was also greater in the postimplementation group (58.7% vs 77.8% at 2 months, P=.04; 50.5% vs. 54.2% at 4 months, P=.06; and 44.0% vs 49.3% at 6 months, P=.12).
Conclusions: Providing on-site IBCLC breastfeeding support services within an academic family medicine clinic is associated with significant increases in breastfeeding, supporting the provision of lactation services on-site where mothers and children receive primary care.

Published: November 2019

Background and Objectives: Clinical coaching programs can improve clinician performance through feedback following direct observation and the promotion of reflection. This study assessed the feasibility and acceptability of a primary care coaching program applied in community-based practices.
Methods: Using a 31-item behavioral checklist that was iteratively revised, four faculty observed 18 community-based primary care clinicians (15 of whom were physicians) across 36 patient encounters. Each behavior was scored as a binary variable (observed or not observed). After watching them care for patients, each clinician participated in a focused feedback session to discuss strengths and areas for improvement.
Results: Behaviors observed with the highest frequency were: reflects compassion (100%), appears to enjoy caring for the patient (100%), leads and follows with open-ended questions (97%), and asks thoughtful and smart questions (95%). Areas for improvement were those behaviors done less commonly: apologizes for running behind schedule (18%), acknowledges computer and/or explains role in patient care (14%), and assesses understanding (teachback; 7%). Most clinicians agreed or strongly agreed that they would like to be coached again in the future (81%), and that the coaching feedback would help them become more effective in primary care practice (94%). Nearly all patients surveyed substantiated that it did not bother them to have another doctor in the room and that it is a good idea to offer coaching to clinicians to help them improve.
Conclusions: Coaching busy primary care clinicians is feasible and a valued experience. Focusing on specific observable behaviors can identify clinicians’ strengths and opportunities for improvement. Patients are pleased to learn that their clinicians are receiving coaching as part of their professional development.

For the difficulty of solving the problem of experimental class mathematical connection ability lies in the percentage of questions number 6 which is 46.9% with indicators applying the relationship of mathematics to everyday problems, while the percentage of achievement in the control class is very low in question number 5 is 46.1% with indicators look for the relationship of one procedure to another in equivalent representations. Learning using the scientific approach and guided inquiry method makes creative students associate concepts or mathematical procedures appropriately.

This study aims to describe the increasement differences of mathematical connection ability (MCA) and differences in self-efficacy (SE) of students in both classes, and the relation of  SE and MCA. The method of this research use quasi-experimental with pretest-posttest control group design. The subjects of the study were 50 students from two classes in the seventh grade determined purposively from one of the schools in Cimahi City. The research instrument consisted of MCA tests and SE scales. Data analysis carried out was percentage calculation, mean difference test, and Pearson correlation test at 5% significance level. The conclusion of the results of this study states that there was a difference in the increasement in MCA between students in both classes in the medium category, where the increasement in MCA of students learning using the PBL approach with multimedia (PBLM) was better than students who used the PBL approach only. There were no differences in SE of students in both research classes and were in a low category. There is a positive relation between SE and MCA in the medium category.
IMPROVING MATHEMATIC CONNECTION AND COMMUNICATION CAPABILITY AND SELF-CONCEPT OF VOCATIONAL SCHOOL STUDENTS THROUGH THE SAINTIFIC APPROACH TO THE SETTINGS OF JIGSAW COOPERATIVE LEARNING MODELS

Published: November 2019

This research was aimed at examining the improving mathematical connection and communication ability and self-concept of vocational students through cooperative learning of jigsaw so that they were able to be more motivated in learning mathematics, more understanding mathematics learning itself and to  apply it in everyday life. This research method was a quasi-pretest-posttest experiment that applied a jigsaw cooperative learning model. This study involved two groups of students who  studied about mathematical connection and communication skills and students' self-concepts. The instruments used were in the form of mathematical connection and communication skills, as well as student self-concept questionnaires. The research instruments were firstly tested for validity (logical and empirical), reliability, distinguishing features and the level of difficulty of the questions. The achievement of mathematical connections and communication skills and the self-concept of students who got learning with a scientific approach to the type of cooperative learning model jigsaw was better than students who only learned the scientific approach. In this study there was also an association between the ability of connections with mathematical communication of students in the high category. There was an association between the ability of connections with students' self-concepts in the high category. There was an association between mathematical communication skills and students' self-concepts in the high category.
Important biological characteristics of Trichinella genotypes
Authors: Petrovic Jelena
Published: November 2019

Background. To control Trichinella, one of the most important food borne parasites, it is necessary to know the biology of the parasite. Scope and Approach. The pathogenicity of Trichinella genotypes mainly depends on its biological characteristics: reproductive capacity index (RCI), infectivity towards different animal species and humans, differences in the number of newborn larvae (NBL) and susceptibility to environmental conditions. Key Findings and Conclusions. Among the Trichinella, T. spiralis has the highest RCI for domestic, synanthropic and some wild animals. This genotype is the most infectious for domestic and wild pigs and has the highest NBL index. T. spiralis is more susceptible to high temperatures, freezing and decay of dead host tissues than the sylvatic genotypes. The pathogenicity of T. spiralis results in its easy and rapid spread across populations of domestic pigs, thus creating opportunities for human disease. T. britovi has a moderate NBL and low RCI for pigs, mice and foxes, but this genotype is resistant to freezing. Other genotypes have high to moderate RCI, NBL and infectivity towards wild animals, have good tolerance towards adverse environmental conditions of low temperature and high humidity, and they usually spread in wild animal populations.
Termodinâmica e Revolução industrial: Uma abordagem por meio da História Cultural da Ciência

ResumoO Ensino de Ciências ainda apresenta vertentes que prezam por práticas pautadas predominantemente na repetição e memorização de exercícios. Essa abordagem leva a dificuldades de aprendizagem dos discentes, bem como, o desinteresse pela ciência e pelo seu processo de construção. Uma das formas de romper com essa abordagem trata-se da utilização da História Cultural Científica no qual a ciência é vista como integrante da cultura humana. Assim sendo, objetivamos elaborar um material didático em formato de texto narrativo histórico que contemplasse a abordagem cultural científica da Termodinâmica pautados nas abordagens internalista e externalista. Para isso utilizamos da pesquisa bibliográfica em fontes secundárias, com o intuito de elucidar as contribuições culturais e científicas da Revolução Industrial para o desenvolvimento da Termodinâmica. Deste modo, foi possível elucidar as necessidades sociais que foram predominantes para o aperfeiçoamento das máquinas térmicas e a evolução dos processos técnicos para os científicos que culminaram nas leis da Termodinâmica. Diante disso, a visão internalista e externalista, foram abordadas de forma integradas permitindo que a narrativa histórica seja uma possibilidade de abordagem da História Cultural Científica.Palavras-chave: Estudo do Calor; História da Ciência; Máquinas Térmicas.AbstractThe teaching of science still presents aspects that emphasize practices based predominantly on repetition and memorization of exercises. This approach leads to learning difficulties of students, as well as the lack of interest in science and its construction process. One of the ways to break with this approach is the use of scientific Cultural history in which science is seen as a member of human culture. Thus, we aim to elaborate a didactic material in a historical narrative format that contemfaced the scientific cultural approach of thermodynamics based on internalist and externalist approaches. For this we use the bibliographic research in secondary sources, with the aim of eluciding the cultural and scientific contributions of the Industrial Revolution for the development of thermodynamics. Thus, it was possible to elucidates the social needs that were predominant for the improvement of the thermal machines and the evolution of the technical processes for the scientific ones that culminated in the laws of thermodynamics. In view of this, the internalist and Externalist vision, were approached in an integrated way allowing the historical narrative to be a possibility of approaching the scientific Cultural historyKeywords: Heat Study; History of Science; Industrial Revolution.

The voices of different kinds (i.e., stated or unstated expectations of the entities) affect the functioning of the systems. Voices of authorities (VoA), processes (VoP) and shareholders (VoS) are seen in controls interacting with an environment. Therefore, control-related indicators are prescriptive, and they provide expectations for the functioning of the systems. In the study, the entity-related approach of the voices (VoA, VoP, and VoS) adapted to formalize rules for the evaluation metadata of the KUVA and SOTKANET indicators the meaning of which is to control welfare and health in Finland. The KUVA indicators are meant to control especially cost-effectiveness. The region classifications of the KUVA and SOTKANET indicators used to figure out whether responsible information providers (VoP) and information consumers (VoA and VoS) can be established. When 15 region classifications mapped within the voices by the nine rules the result of which was that nine region classifications mapped within VoA, three within VoS, and two within VoP. The main information providers are municipalities and hospital districts and municipalities. Despite our metadata-based KUVA and SOTKANET content research, without the deployment instructions of the indicators, the municipalities and other service providers do not get a complete picture of how the authorities and shareholders see them and what is expected of them, i.e., control-related cost-effectiveness will not be transparent.
Membangun Pendidikan Berwawasan Gender

The role of women in national development is increasingly significant and should not be underestimated. To build human resources for women, education is needed that upholds gender equality so that their rights to education can be realized. But inevitably, education in Indonesia in its history has experienced a dark period where women lacked rights in education. There was once a gender gap in the world of education in Indonesia. There are several factors that influence it, such as community culture and school structure systems that lack opportunities for women to take part. Therefore, gender-conscious education needs to be realized in order to address the gender issue. One effort to realize gender-oriented education can be by developing a gender-sensitive learning process approach through fostering and training teachers, principals, and education supervisors, as well as at the level of decision making in all national education management units.
