Published: December 2015

Abstract
Background
Epidemiological analyses of aggregated data are often used to evaluate theoretical health effects of natural disasters. Such analyses are susceptible
to confounding by unmeasured differences between the exposed and unexposed populations. To demonstrate the difference-in-difference method our population included all recorded Florida live births that reached 20 weeks gestation and conceived after the first hurricane of 2004 or in 2003 (when no hurricanes made landfall). Hurricane exposure was categorized using ≥74 mile per hour hurricane wind speed as well as a 60 km spatial buffer based on weather data from the National Oceanic and Atmospheric Administration. The effect of exposure was quantified as live birth rate differences and 95 % confidence intervals [RD (95 % CI)]. To illustrate sensitivity of the results, the difference-in-differences estimates were compared to general linear models adjusted for census-level covariates. This analysis demonstrates difference-in-differences as a method to control for time-invariant confounders investigating hurricane exposure on live birth rates.

Results
Difference-in-differences analysis yielded consistently null associations across exposure metrics and hurricanes for the post hurricane rate difference between exposed and unexposed areas (e.g., Hurricane Ivan for 60 km spatial buffer [−0.02 births/1000 individuals (−0.51, 0.47)]. In contrast, general linear models suggested a positive association between hurricane exposure and birth rate [Hurricane Ivan for 60 km spatial buffer (2.80 births/1000 individuals (1.94, 3.67)] but not all models.

Conclusions
Ecological studies of associations between environmental exposures and health are susceptible to confounding due to unmeasured population attributes. Here we demonstrate an accessible method of control for time-invariant confounders for future research.

Published: December 2015

Abstract
Background
Conflicts during communication in multi-ethnic healthcare settings is an increasing point of concern as a result of societies’ increased ethno-cultural diversity. We can expect that conflicts are even more likely to arise in situations where difficult medical decisions have to be made, such as critical medical situations in hospital. However, in-depth research on this topic is rather scarce. During critical care patients are often unable to communicate. We have therefore investigated factors contributing to conflicts between healthcare professionals and family members from ethnic minority groups in critical medical situations in hospital.

Methods
Ethnographic fieldwork was done in one intensive care unit of a multi-ethnic urban hospital in Belgium over 6 months (January 2014 to June 2014). Data were collected through negotiated interactive observation, in-depth interviews with healthcare professionals, from patients’ medical records, and by making notes in a logbook. Data were analysed by using grounded theory procedures.

Results
Conflicts were essentially related to differences in participants’ views on what constitutes ‘good care’ based on different care approaches. Healthcare professionals’ views on good care were based predominantly on a biomedical care model, whereas families’ views on good care were mainly inspired by a holistic lifeworld-oriented approach. Giving good care, from the healthcare professionals’ point of view, included great attention to regulations, structured communication, and central decision making. On the other hand, good care from the families’ point of view included seeking exhaustive information, and participating in end-of-life decision making. Healthcare professionals’ biomedical views on offering good care were strengthened by the features of the critical care context whereas families’ holistic views on offering good care were reinforced by the specific characteristics of families’ ethno-familial care context, including their different ethno-cultural backgrounds. However, ethno-cultural differences between participants only contributed to conflicts in confrontation with a triggering critical care context.

Conclusions
Conflicts cannot be exclusively linked to ethno-cultural differences as structural, functional characteristics of critical care substantially contribute to the development of conflicts. Therefore, effective conflict prevention should not only focus on ethno-cultural differentness but should also take the structural organizational characteristics of the critical care context sufficiently into account.
The 5As team intervention: bridging the knowledge gap in obesity management among primary care practitioners
Authors: Ogunleye Ayodele A. , Osunlana Adedayo , Asselin Jodie , Cave Andrew , Sharma Arya Mitra , Campbell-Scherer Denise Lynn 
Published: December 2015

Abstract

Background
Despite opportunities for didactic education on obesity management, we still observe low rates of weight management visits in our primary care setting. This paper describes the co-creation by front-line interdisciplinary health care providers and researchers of the 5As Team intervention to improve obesity prevention and management in primary care.

Methods
We describe the theoretical foundations, design, and core elements of the 5AsT intervention, and the process of eliciting practitioners’ self-identified knowledge gaps to inform the curricula for the 5AsT intervention. Themes and topics were identified through facilitated group discussion and a curriculum relevant to this group of practitioners was developed and delivered in a series of 12 workshops.

Result
The research question and approach were co-created with the clinical leadership of the PCN; the PCN committed internal resources and a practice facilitator to the effort. Practice facilitation and learning collaboratives were used in the intervention For the content, front-line providers identified 43 topics, related to 13 themes around obesity assessment and management for which they felt the need for further education and training. These needs included: cultural identity and body image, emotional and mental health, motivation, setting goals, managing expectations, weight-bias, caregiver fatigue, clinic dynamics and team-based care, greater understanding of physiology and the use of a systematic framework for obesity assessment (the “4Ms” of obesity). The content of the 12 intervention sessions were designed based on these themes. There was a strong innovation values fit with the 5AsT intervention, and providers were more comfortable with obesity management following the intervention. The 5AsT intervention, including videos, resources and tools, has been compiled for use by clinical teams and is available online at http://www.obesitynetwork.ca/5As_Team.

Conclusions
Primary care interdisciplinary practitioners perceive important knowledge gaps across a wide range of topics relevant to obesity assessment and management. This description of the intervention provides important information for trial replication. The 5AsT intervention may be a useful aid for primary care teams interested to improve their knowledge of obesity prevention and management.

Comparison of uterine and tubal pathology identified by transvaginal sonography, hysterosalpingography, and hysteroscopy in female patients with infertility
Authors: Phillips Catherine H. , Benson Carol B. , Ginsburg Elizabeth S. , Frates Mary C. 
Published: December 2015

Abstract
Background
The causes of female infertility are multifactorial and necessitate comprehensive evaluation including physical examination, hormonal testing, and imaging. Given the associated psychological and financial stress that imaging can cause, infertility patients benefit from a structured and streamlined evaluation. The goal of such a work up is to evaluate the uterus, endometrium, and fallopian tubes for anomalies or abnormalities potentially preventing normal conception. To date, the standard method for assessing these structures typically involves some combination of transvaginal sonography (TVS), hysterosalpingography (HSG), and hysteroscopy (HSC). The goal of this review is to compare the diagnostic accuracy of TVS, HSG, and HSC for diagnosing abnormalities in infertility patients to determine if all studies are necessary for pre-treatment evaluation.

Results
We identified infertility patients prior to initiation of assisted reproductive technology who had baseline TVS, HSG, and HSC within 180 days of each other. From medical record review, we compared frequencies of each finding between modalities. Of the 1274 patients who received a baseline TVS over 2 years, 327 had TVS and HSG within 180 days and 55 patients had TVS, HSG and HSC. Of the 327, TVS detected fibroids more often than HSG (74 vs. 5, p < .0001), and adenomyosis more often than HSG (7 vs. 2, p = .02). HSG detected tubal obstruction more often than TVS (56 vs. 8, p = .002). Four (1.2 %) patients had endometrial polyps on both HSG and TVS.
In the 55 patients with HSG, TVS, and HSC, HSC identified endometrial polyps more often than TVS (10 vs. 1, p = .0001) and HSG (10 vs. 2, p = .0007). TVS detected more fibroids than HSC (17 vs. 5, p < .0001). Tubal obstruction was identified more often by HSG than HSC (19 vs. 5, p < .0001).

Conclusions
TVS is superior for evaluation of myometrial pathology. HSG is superior for evaluation of tubal pathologies. Endometrial pathologies are best identified with HSC.

AbstractWe have shown that GnRH-mediated engagement of the cytoskeleton induces cell movement and is necessary for ERK activation. It also has previously been established that a dominant negative form of the mechano-GTPase dynamin (K44A) attenuates GnRH activation of ERK. At present, it is not clear at what level these cellular events might be linked. To explore this, we used live cell imaging in the gonadotrope-derived αT3–1 cell line to determine that dynamin-green fluorescent protein accumulated in GnRH-induced lamellipodia and plasma membrane protrusions. Coincident with translocation of dynamin-green fluorescent protein to the plasma membrane, we demonstrated that dynamin colocalizes with the actin cytoskeleton and the actin binding protein, cortactin at the leading edge of the plasma membrane. We next wanted to assess the physiological significance of these findings by inhibiting dynamin GTPase activity using dynasore. We find that dynasore suppresses activation of ERK, but not c-Jun N-terminal kinase, after exposure to GnRH agonist. Furthermore, exposure of αT3–1 cells to dynasore inhibited GnRH-induced cyto-architectural rearrangements. Recently it has been discovered that GnRH induced Ca2+ influx via the L-type Ca2+ channels requires an intact cytoskeleton to mediate ERK phosphorylation. Interestingly, not only does dynasore attenuate GnRH-mediated actin reorganization, it also suppresses Ca2+ influx through L-type Ca2+ channels visualized in living cells using total internal reflection fluorescence microscopy. Collectively, our data suggest that GnRH-induced membrane remodeling events are mediated in part by the association of dynamin and cortactin engaging the actin cytoskeleton, which then regulates Ca2+ influx via L-type channels to facilitate ERK phosphorylation.

Published: December 2015

Abstract
A 70-year-old diabetic female patient presented with fatigue, headaches, hallucinations and shivers following a history of sinusitis and ophthalmitis. She had an aortic surgery performed 7 years ago for a stenotic and regurgitant aortic valve with aneurysm of the ascending aorta. Work-up brain MRI revealed septic–embolic encephalitis. Multimodality cardiovascular imaging showed abnormal anterior wall of the ascending aortic graft with vegetation extending into the lumen. Blood culture was only positive for Aggregatibacter actinomycetemcomitans, an uncommon cause of infective endocarditis. During aortic surgery, the intraluminal vegetation with suppurated perigraft tissue was confirmed.

Beliefs and attitudes towards social network advertising: A cross-cultural study of Saudi and Sudanese female students
Authors: Mansour Ilham H. F. 
Published: December 2015

Abstract
The study aims to investigate the possible differences in beliefs and attitudes towards social network advertising that may exist among women in Saudi Arabia and Sudan and specify the factors that influence their attitude towards social network advertising. Data sets of two samples from Saudi Arabia (169) and Sudan (195) were collected using a survey of female students from both countries. A t-test was then applied on the processed data, together with correlation and regression analysis, in order to answer the posited research questions. The results revealed no significant differences in attitude towards social media advertising between the two samples, although significant differences in beliefs about social network advertising were documented. In addition, the results indicate that five of the individual factors are statistically significant: these are prior web experience, entertainment, credibility and social norms for the Saudi sample and informativeness, entertainment, credibility and irritation for the Sudanese sample. This study provides insights for international marketers in terms of attitudes and beliefs towards social network advertising. The results may offer some valuable information that may aspire to improve marketing-related activities aimed at social media users.
‘Don’t know’ responses in American polls about Arab countries: More than just ‘No Opinion’?
Authors: Nada Ayman Mansour , Mesbah Hesham , Becker Lee B. 
Published: December 2015

Abstract
This study examines the factors that determine the use of ‘don’t know’ (DK) responses in American public opinion polls about Arab countries. The data show that the American respondents tend to use the DK option more often when asked about their overall attitudes towards these countries. Drawing on a series of telephone surveys conducted by Gallup (2000–2013) that used national samples (N=13,527 in fourteen surveys), the findings show that DK responses are used to conceal positive or neutral attitudes towards Arab countries rather than to express no opinion. The use of DK was significantly related to general favourable attitudes. The respondents who sympathized more with the Palestinian Arabs against the Israelis in the Middle East conflict, and those who had a relatively overall positive attitude towards the Arab world, were more likely to use DK when asked about their attitudes about Arab countries. The findings also show that the use of the news media (following international news) and demographics (age, gender and education) have a significant impact on the probability of providing DK responses. The findings also indicate that respondents’ cognitive sophistication enhanced opinion formation.

Published: December 2015

Objective: With the scientific and technological advances, the life expectancy of the population has increased over the years. With the advent of dental implants, a new possibility of treatment for oral rehabilitation was created to help or even help overcome the limits of conventional fixed dentures, removable and mainly total. Compared to conventional rehabilitation treatment on natural teeth, rehabilitation on implants has higher rates of success and longevity. Material and Methods: For this research we evaluated the medical records of patients who received surgical treatment for implant placement in the update current school of Implantology ECO (Continuing Studies in Dentistry) in São José dos Campos, in the 2008 'period to 2012, in order to obtain, analyze and relate the following criteria: the patient gender; year and number of installed dental implants; the region of implant installation; the trademark of the installed implant and the successful osseointegration, or process in which there is a rigid fixation between the living bone and the surface of the implant installed. Results: According to the analyzed data, it was observed, along five years, a total of 434 implants placed in patients, mostly women in the mandibular region. However, the total loss was of 5 implants, most in the maxilla and in men, 3 of these, cone-Morse implants, one internal and one external hexagon. Conclusion: Thus, the success rate in the osseointegration implants seems to be more influenced by patient selection and surgical and prosthetic guidelines, compared the experience of the dentist.

Abstract
Araujo, MP, Nóbrega, ACL, Espinosa, G, Hausen, MR, Castro, RRT, Soares, PP, and Gurgel, JL. Proposal of a new specific cardiopulmonary exercise test for taekwondo athletes. J Strength Cond Res 31(6): 1525–1535, 2017—The objective of this study is to evaluate the cardiorespiratory variables of Taekwondo athletes while performing incremental exercise test on an ergometer using a ramp protocol and to propose a specific protocol for assessing these physiological variables during Taekwondo practice. Fourteen athletes participated in 2 incremental exercise tests: a treadmill exercise test (TREADtest) and a Taekwondo-specific exercise test (TKDtest). The TKDtest consists in 1-minute stages of kicks with an incremental load between then. The subjects perform kicks each time a sound signal was heard. Heart rate (HR), oxygen uptake (V̇o
2), and their reserve correspondents (V̇o
2R and reserve heart rate [HRR]) were divided into quartiles to verify their kinetics along the tests. Significant difference between 2 tests was found only for V̇o
2R (p = 0.03). Regarding the quartiles, significant differences were found for HR in the first (p = 0.030) and second (p = 0.003). Analyzing the regression curves, significant differences were found for HR for intercept (p = 0.01) and slope (p = 0.05) and HRR for slope (p = 0.02). Analysis showed that significant reliability, with intraclass correlation coefficient (ICC), was found for the V̇o
2peak (ICC = 0.855, p = 0.003), V̇o
2 in ventilatory thresholds 1 (ICC = 0.709, p = 0.03) and 2 (ICC = 0.848, p = 0.003). Bland-Altman analyses reported a mean difference ± the 95% limits of agreement of 2.2 ± 8.4 ml·kg−1·min−1 to V̇o
2peak. The TKDtest is reliable for measurement of cardiorespiratory variables, and the behavior of these variables differs mainly from TREADtest, probably because of the motor task performed.
REVISIÓN Y ADAPTACIÓN DEL CONCEPTO “INNOVACIÓN” AL CONTEXTO EMPRESARIAL ESPAÑOL
Authors: Platero Jaime Manuel 
Published: December 2015

La innovación se ha convertido en una realidad innegable en el contexto de la gestión de la empresa, independientemente de su tamaño o actividad. En las últimas décadas, numerosas investigaciones han estudiado la capacidad innovadora de la empresa, sus consecuencias macroeconómicas y la relación que guarda la innovación con ciertos factores macros y micros. En este sentido, algunos trabajos han analizado la influencia de determinados factores en la capacidad innovadora de las empresas, prestando especial atención a la de gran tamaño y descuidando en ocasiones el análisis en el ámbito de las empresas de estructuras más reducidas que suelen tener otro tipo de recursos y capacidades, muy diferentes a los que representan a las más grandes. Precisamente este trabajo pretende contribuir a mejorar el conocimiento sobre la innovación empresarial en entidades organizativas de tamaño más limitado, que son las que más peso tienen en la mayoría de las economías emergentes y desarrolladas. Este trabajo pretende estudiar y evaluar la evolución que presenta el concepto “innovación”, para redefinirlo y adaptarlo a las características intrínsecas de la microempresa española. Con ello, se pretende contribuir a mejorar el conocimiento sobre la innovación y sus formas en el contexto de las microempresas de España y sentar las bases conceptuales para futuras investigaciones en el ámbito de las pequeñas empresasAbstractInnovation has become an undeniable reality in the management of the firm, regardless of size or activity. In recent decades, numerous studies have examined the innovative capacity of the company, its macroeconomic consequences and the relationship of innovation with certain macro and micro factors. In this sense, some studies have analysed the influence of certain factors on the innovative capacity of enterprises, paying special attention to large business and sometimes neglecting the analysis in the area of smaller companies. Precisely this work tries to improve the knowledge about business innovation in organizational entities of more limited size, which are those that have more weight in most emerging and developed economies. This work aims to study and analyse the evolution of the concept "innovation" in order to redefine and adapt this concept to the intrinsic characteristics of the Spanish microenterprise. This study try to improve the understanding of innovation and its forms in the Spanish context, and lay the conceptual foundation for future research in the field of small businesses.
