Agonizing and Expensive: A Review of Institutional Costs of Ankle Fusion Nonunions
Authors: Gagne Oliver J. , Veljkovic Andrea N. , Glazebrook Mark , Penner Murray , Wing Kevin , Younger Alastair S. E.
Published: April 2020

Nonunion after ankle arthrodesis requiring revision is a challenging operative complication, and bone graft substitutes are costly. This study sought to summarize all institutional expenditures related to the revision of an ankle fusion nonunion, presuming that cost and skin-to-skin time would exceed those of the index surgery. The electronic records from 2 foot and ankle centers were reviewed, leading to a list of patients with 2 or more entries for tibiotalar fusions being generated. A total of 24 cases were found to match the criteria. Demographic factors and skin-to-skin time of the remaining patients were compiled. This cohort included 24 patients (6 female and 18 male) with a mean age of 64 years and body mass index of 30.4 kg/m
2
. Supplemental clinic visits and investigations were included either after computed tomography to assess union or 365 days after index surgery. Total cost of the revision was calculated from billing codes, length of operation, and period of hospitalization. Postrevision outpatient fees were included as well. The revisions were performed open in all cases, and 21 patients received autograft and/or bone substitute. Mean postoperative hospitalization was 3 days. The additional costs (in US dollars) associated with nonunion were $1061 for imaging, $627 for prerevision visits, $3026 for the revision, $3432 for the hospital stay, and $1754 for postrevision follow-up. The total mean amount was $9683, equivalent to 9 nights of acute inpatient stay. Mean index skin-to-skin time was 114 minutes, being 126 minutes for revisions (
P
=.26). Additional care related to ankle fusion nonunion represents a financial burden equivalent to 9 nights of acute inpatient stay. The use of an orthobiologic would need to be less than $436 to be cost saving. Revision surgery is not significantly longer intraoperatively than index surgery. [

Preservation of the Tibial Remnant in Anterior Cruciate Ligament Reconstruction May Improve Postoperative Proprioceptive Function
Authors: Lee Byung-Ill , Kim Chang Hyun , Jang Byung Woong , Hong Yong Cheol , Kwon Sai-Won
Published: April 2020

The purpose of this study was to retrospectively compare clinical results, including proprioceptive function, after anterior cruciate ligament (ACL) reconstruction between 2 groups using techniques that preserve and eliminate the tibial remnant. Forty-eight patients who were followed for at least 24 months after ACL reconstruction with 4-strand hamstring tendon autografts were enrolled in this study. They were then divided into 2 groups: the remnant-preserving group (group A, 26 patients), in whom more than 7 mm of the remnant tibial stump (approximately 20% of the mean length of the ACL) was preserved; and the remnant-eliminating group (group B, 22 patients), in whom the tibial remnant was eliminated during ACL reconstruction. The average duration of follow-up was 25.5 months. At last follow-up, patients were evaluated using the International Knee Documentation Committee scale, Hospital for Special Surgery score, Lachman test, arthrometer, reproduction of passive positioning (RPP) test, threshold to detection of passive motion (TTDPM) test, one-leg hop test, and single-limb standing test. The clinical results between the 2 groups were statistically compared. Group A showed significantly better results on the RPP test at 15° (
P
=.040) and 30° (
P
=.010), one-leg hop test (
P
=.017), and single-limb standing test (
P
=.007) compared with group B. The other results showed no significant differences. The remnant-preserving technique in ACL reconstruction yields better proprioceptive and functional outcomes and may help achieve postoperative patient satisfaction. [

Holocene high floods on the Planina Polje, Classical Dinaric Karst, Slovenia
Authors: Stepišnik Uroš , Ferk Mateja , Gostinčar Petra , Černuta Luka
Published: April 2020

The Planina Polje is located in the northwestern part of Notranjsko Podolje, Slovenia. Annual floods cover the flattened floor of the polje at elevation 445 m a.s.l. and reach the depth of approximately 8 meters. Loamy sediments which were found on surface and subsurface features from the inflow part of Planina Polje up to the elevations of about 495 m a.s.l., indirectly show that floods in the past must have been much more extensive than the recent ones. Radiocarbon dating of flowstone layer from side passage Tiha Jama in Planina Cave revealed that the last such extreme floods appeared around 5,706 ± 49 BP. The time frame of the flood roughly corresponds with the Altithermal (8,000–5,000 BP). More humid mid-Holocene climate might be the main cause for the high floods on Planina Polje.Keywords: geomorphology, floods, radiocarbon dating (14C), Dinaric Karst, Planina Polje, Planina Cave.
New data on the dolines of Velebit Mountain: An evaluation of their sedimentary archive potential in the reconstruction of landscape evolution
Authors: Ballut Christèle , Faivre Sanja
Published: April 2020

The first approach to the relationships between societies and physical environments on Velebit Mountain shows narrow correlations between spatial distribution of dolines, soil formation, hydric resources, vegetation and land occupation. In 2002, sediment cores have been obtained from different dolines of Velebit Mountain to evaluate the potential of their sedimentary archives in order to reconstruct the landscape history. On the littoral slopes and on the top parts of the mountain, the dolines were difficult to dig due to the presence of rocks in depth. Nevertheless, the cores have been sampled and soil analyses have been made (physical and chemical analyses: colour, grain size, pH, CaCO3, C, N, P, K, Mg, CEC). No dating materials were found. The first results attest to rather homogeneous pedologic processes in each area studied (Kamenica, Stinica, Baške Oštarije and Bilensko Mirevo), but they also indicate colluvial contributions. These contributions differ from one doline to another according to their location and morphology. Dolines reveal themselves to be not very good traps, as the representative nature of their sedimentary archives could be very local. However, the best profile has been obtained at Bilensko Mirevo, which shows a change in the soil nutrient content from an impoverishment in its middle part toward an increase of the soil nutrients in recent parts. Those environmental changes could not be precisely dated, but could be correlated with the 17th to 20th century phase of strong human impact on the Velebit environment and with the rural depopulation observed since the second half of the 20th century.Keywords: karst, dolines, Mediterranean soils, Velebit Mountain,Dinarides, Croatia.
Preliminary study for the adaptation of the »Heaven's Cave« for tourist purposes (Phong Nha-Ke Bang national park, Vietnam)
Authors: Debevec Bogdan , Knez Martin , Kranjc Andrej , Pahor Marko , Prelovšek Mitja , Slabe Tadej
Published: April 2020

Heaven’s Cave is located in the centre of the Phong Nha-Ke Bang national park, about 500  km southern from the Vietnamese capital and 40 km from the city of Dong Hoi. Phong Nha-Ke Bang national park is protected also as a UNESCO world heritage site. Due to weak economic situation in this region as a result of lack of natural resources, karst tourism represents an important opportunity for raising the quality of live in the province. A proposal to adapt non-touristic Heaven’s Cave for tourism was presented to Karst Research Institute ZRC SAZU in 2006. Because the caves are sensitive ecosystems and all activities in them should be carefully implemented, our task was to make basic survey and map the cave, to perform a speleological and touristic research, to propose possible interventions for adapting the cave for tourism and to prepare a strategy for tourism development in this area. The latter should also show us if some interest is present among tourists for new show cave in this region. From this point of view this study does not represent systematic long-term approach for adapting a cave for tourism but rather a short study of a cave with potential to be show cave in remote area of Central Vietnam. Approach used in this study should be used in similar environments as a first step to estimate if weakly known cave is environmentally and economically suitable for development for touristic purposes.Keywords: Heaven’s Cave, Thien Duong Cave, Phong Nha-Ke Bang, Vietnam, show cave.
Transport and consumption of organic detritus in a neotropical limestone cave
Authors: Silva Marconi Souza , Ferreira de Oliveira Bernardi Leopoldo , Martins Rogério Parentoni , Ferreira Rodrigo Lopes
Published: April 2020

Caves are permanently aphotic environments, a fact that precludes the occurrence of photosynthetic organisms. In these systems the resource is allochthonous, coming mainly from the surrounding epigean environment, being imported by physical and biological agents. Even knowing about the importance of the organic allochthonous resources in caves, little is known of their importation and processing. The present work had as an objective, the measuring the coarse particulate organic matter processing and import rates in the subterranean environment. The cave studied was Lapa da Fazenda Extrema I, limestone cave, located in Brazilian savanna biome. Through bimonthly collections, it was observed that the organic detritus penetrated into the cave in low amounts in dry season and high amounts in rainy season. The processing of the organic plant matter in the aquatic hypogean environment was moderate (K-day=0.025), in the epigean environment the processing was predominantly slow (K-day =0.0104). The detritus commonly brought to the interior of the cave were large woods (58.18 g/day), followed by leaves and fragmented material (12.76 g/day), fruits and seeds (0.0069 g/day), animal carcasses (0.002 g/day) and roots (0.001 g/day). The highest richness and abundances of invertebrates were found in the same periods in which there were the highest rates of organic matter import to the cave.Keywords: cave, detritus processing, energy flow.

The Distribution of the Suffixes ‑ica and ‑ka with Emphasis on Feminine Derivation
Authors: Markežič Tjaša
Published: April 2020

This article is based on a pilot study of the appearance of the suffixes ‑ica and ‑ka with variants in word-formational semantic groups based on material from the Standard Slovenian Dictionary (SSKJ) and the Gigafid corpus. The study showed that the two suffixes are used to form feminine nouns in 38% of cases in SSKJ and 37% of cases in the corpus. For a more detailed analysis, additional material was therefore extracted from the work New Slovenian Vocabulary and the bachelor’s thesis Newly Coined Words for Designating People in Slovenian in order to determine which suffix is more frequent in feminine noun formation.
A Circum-Pannonian Word-Prosodic Parallel: Paroxytonic Accent in the South-West Bohemian Dialect
Authors: Holub Zbyněk
Published: April 2020

Slavists generally think of the Czecho-Slovak dialect area as having a wordprosody configuration of fixed word-initial stress with contrastive length possible in any syllable. A notable exception is the Silesian dialect area, which typically has the Polish configuration with fixed penultimate stress and no contrastive length. Much less familiar is a small area in SW Bohemia (Pilsen, České Budějovice and environs) with what has been termed “paroxytonic stress” and contrastive length, which at first blush may be considered akin to the Silesian configuration.

Multinational Enterprises and African Economy
Authors: Okon Edet E.
Published: April 2020

Africa's economy, an emerging economy is gradually being re-positioned in the global economy as a focus of investment. Multinational Enterprises (MNEs) have helped to shape the economy of Africa. An overview of Africa's economy was examined; top 20 Africa's largest economies were highlighted; major sectors perceived as paths to growth of Africa's economy were examined – Agriculture, Banking, Consumer goods, infrastructure, mining, oil and gas, and telecommunications. The chapter also enunciated the concept, ‘diversified economy' in relation to oil exporters, the transition economies and the pre-transition economies. It is therefore concluded that Multinational Enterprises will continue to contribute to the growth of Africa's economy, especially as more indigenous enterprises are being launched by African countries. It is therefore recommended that African countries should continue to diversify her economy to take advantage of large labor potential and natural resources endowment.
African Women and Economic Development
Authors: Maloiy Lanoi
Published: April 2020

There is a recognition that African women are amongst the world's poorest; however, they are also the most industrious. As such, African women's lives present a contradiction. This chapter examines the contradictory nature of African women's lives using a case study of Kenyan women. A possible reason for this contradiction is that African women face many barriers when attempting to access education, careers, and economic resources. These barriers often originate from political, social, and cultural factors. Given the prominence and extent of these barriers, it is important to not only identify them but to comprehend them as well. The chapter examines how these factors contribute to the feminization of poverty in Africa with a particular focus on Kenya.
Activities of Home-Based Heart Failure Nurse Specialists: A Modified Narrative Analysis
Authors: Davidson Patricia , Paull Glenn , Rees David , Daly John , Cockburn Jill
Published: April 2020

• Background Heart failure nurse specialists strive to optimize patients’ outcomes in home-based settings.

• Objective To document the activities of home-based heart failure nurse specialists.

• Method A modified narrative analysis of clinical notes of home-based heart failure nurse specialists during a 12-month period was used.

• Results Data analysis revealed 7 key activities of home-based heart failure nurse specialists: (1) monitoring signs and symptoms and reinforcing patients’ self-management: identifying trends and appropriate action; (2) organization, liaison, and consultation with other health professionals to deal with changes in clinical status; (3) clarifying and reinforcing patients’ self-care strategies; (4) assisting patients in their desire to avoid institutionalized care; (5) identifying patients’ psychosocial issues: dealing with social isolation; (6) providing support: journeying with patients and patients’ families; and (7) helping patients and patients’ families deal with death and dying.

• Conclusions A major proportion of the activities of home-based heart failure nurse specialists are related to facilitating communication between health professionals and providing information and support to patients and patients’ families.
Critical Care Providers’ Perceptions of the Use of Vasopressin in Cardiac Arrest
Authors: Heath Janie , Hanson Dave , Long Rebecca , Crowell Nancy A.
Published: April 2020

• Background Although published algorithms and guidelines list epinephrine and vasopressin as either/or choices for treatment of ventricular fibrillation and/or pulseless ventricular tachycardia, little is known about how critical care providers respond to this recommendation.

• Objectives To assess the use of vasopressin as a first-line drug of choice for ventricular fibrillation and/or pulseless ventricular tachycardia and describe factors that may influence decision making for using vasopressin.

• Methods A convenience sample from 4 academic medical centers in the United States was recruited to complete a 20-item survey on demographic factors such as year of last Advanced Cardiac Life Support (ACLS) provider course, specialty certification, predominant practice responsibility, and beliefs related to the use of vasopressin for cardiac arrest. Descriptive statistics, Pearson correlation analysis, and logistic regression were used to analyze the data.

• Results A total of 214 critical care providers (80% registered nurses) completed the survey. Year of last ACLS course (r = −0.188, P = .006) was a significant demographic factor, and behavioral beliefs (attitude about using vasopressin) had the strongest relationship (r = 0.687, P < .001) and were the best predictor for intentions to use or recommend the use of vasopressin (beta=0.589, P<.001).

• Conclusions Despite the recommendation for vasopressin as an agent equivalent to epinephrine for treatment of ventricular fibrillation and/or pulseless ventricular tachycardia, 63% of respondents used epinephrine as a first-line drug of choice. More research is needed to address the classification system for interpreting the quality of evidence that may influence practice.
Providing a “Good Death”: Critical Care Nurses’ Suggestions for Improving End-of-Life Care
Authors: Beckstrand Renea L. , Callister Lynn Clark , Kirchhoff Karin T.
Published: April 2020

• Background Providing appropriate end-of-life care has become a primary concern of nurses and the public. The highly technological critical care environment may not facilitate such care.

• Objective To collect suggestions from critical care nurses for improving end-of-life care in intensive care units.

• Methods A geographically dispersed, random sample of 1409 members of the American Association of Critical-Care Nurses was sent a 72-item survey on perceptions of end-of life care. The survey included a request for suggestions on ways to improve end-of life care.

• Results Of the 861 critical care nurses who responded to the survey, 485 offered 530 suggestions for improving end-of-life care. Providing a “good death” was the major theme; specific suggestions included ways to help ensure death with dignity and peace. Barriers to providing good deaths included nursing time constraints, staffing patterns, communication challenges, and treatment decisions that were based on physicians’ rather than patients’ needs. Suggestions for providing a good death included facilitating dying with dignity; not allowing patients to be alone while dying; managing patients’ pain and discomfort; knowing, and then following, patients’ wishes for end-of-life care; promoting earlier cessation of treatment or not initiating aggressive treatment at all; and communicating effectively as a health-care team. Educational initiatives for professionals and the public were also suggested.

• Conclusions Implementation of specific suggestions provided by experienced critical care nurses might increase the quality of end-of-life care, facilitating a good death for intensive care patients.
Improving Adherence to a Mechanical Ventilation Weaning Protocol for Critically Ill Adults: Outcomes After an Implementation Program
Authors: McLean Suzanne E. , Jensen Louise A. , Schroeder Dallas G. , Gibney Noel R. T. , Skjodt Neil M.
Published: April 2020

• Background Despite multiple reminders, education sessions, and multidisciplinary team involvement, adherence to an evidence-based mechanical ventilation weaning protocol had been less than 1% in a general systems intensive care unit since implementation.

• Objective To assess the effectiveness of using an implementation program, the Model for Accelerating Improvement, to improve adherence and clinical outcomes after restarting a mechanical ventilation weaning protocol in an adult general systems intensive care unit.

• Methods A prospective comparative design, before and after implementation of the Model for Accelerating Improvement, was used with a consecutive sample of 129 patients and 112 multidisciplinary team members. Clinical outcomes were rate of unsuccessful extubations, rate of ventilator-associated pneumonia, and duration of mechanical ventilation; practice outcomes were staff’s understanding of the mechanical ventilation weaning protocol, perceptions of the practice safety climate, and adherence to the weaning protocol.

• Results After the intervention, the rate of unsuccessful extubations decreased, and staff’s understanding of and adherence to the weaning protocol increased significantly. The rate of ventilator-associated pneumonia, duration of mechanical ventilation, and staff’s perceptions of the practice safety climate did not change significantly.

• Conclusion Implementing the Model for Accelerating Improvement improved understanding of and adherence to protocol-directed weaning and reduced the rate of unsuccessful extubations.
Factors Influencing Length of Stay in the Intensive Care Unit
Authors: Gruenberg David A. , Shelton Wayne , Rose Susannah L. , Rutter Ann E. , Socaris Sophia , McGee Glenn
Published: April 2020

• Background Long stays in the intensive care unit are associated with high costs and burdens on patients and patients’ families and in turn affect society at large. Although factors that affect length of stay and outcomes of care in the intensive care unit have been studied extensively, the conclusions reached have not been reviewed to determine whether they reveal an organizational pattern that might be of practical use in reducing length of stay in the unit.

• Objective To identify and categorize the factors associated with prolonged stays in the intensive care unit and to describe briefly the nonmedical interventions to date designed to reduce length of stay.

• Methods Articles published between January 1990 and March 2005 in English-language journals indexed by MEDLINE were searched for studies on outcomes and costs of care in the intensive care unit and on care at the end of life.

• Results The emerging consensus is that length of stay in the intensive care unit is exacerbated by several increasingly discernible medical, social, psychological, and institutional factors. At the same time, several nonmedical, experimental interventions have been designed to reduce length of stay.

• Conclusions Interventions involving palliative care, ethics consultations, and other methods to increase communication between healthcare personnel, patients, and patients’ families may be helpful in decreasing length of stay in the intensive care unit. Further studies are needed to provide a strategy for targeting specific risk factors indicated by the literature review.

Published: April 2020

O estudo avalia a relação entre exportação e produtividade agrícola brasileira. Além de verificar a diferença entre média de exportação e produtividade agrícola nas regiões brasileiras, o estudo usa o teste de causalidade proposto por Hurlin e Venet (2008) para o painel dos estados brasileiros de 2000 a 2015. O principal resultado sustenta a precedência temporal das exportações para a produtividade agrícola. Esse resultado manteve-se ao analisar as regiões de forma desagregada, especificamente Centro-Sul e Norte-Nordeste. Logo, além de gerar divisas para a economia brasileira, as exportações agrícolas podem gerar externalidades positivas no processo produtivo.

Published: April 2020

O presente artigo pretende verificar a eficiência do mercado futuro brasileiro para a commodity café arábica, de acordo com os contratos negociados na B3 no período de 2007 a 2017. Para isto, aplicou-se o método dos mínimos quadrados ordinários e regressão quantílica. Os resultados indicaram que as séries são estacionárias de 1ª ordem e o teste de Engle e Granger indicou que os modelos são cointegrados. Os testes dos resíduos impossibilitaram a interpretação do MQO, indicando que seu uso não é adequado. Entretanto, o mesmo não ocorre com a regressão quantílica, que apresentou no longo prazo um aumento da taxa ótima e da eficiência de mercado, com prêmio ao risco onde as oscilações de preços foram maiores e no curto prazo ocorre o oposto.

A análise morfométrica de bacias hidrográficas fornece dados que possibilitam a compreensão do regime hidrológico, bem como das vulnerabilidades quanto a enchentes, inundações, erosões e manutenção da rede de drenagem. Neste contexto, este artigo tem como objetivo analisar a morfometria da Bacia Hidrográfica Paraguai/Jauquara, Mato Grosso. Os dados para os cálculos de 14 parâmetros morfométricos foram gerados, armazenados e processados por meio de geotecnologias. Os resultados indicaram que a bacia é vulnerável quanto a manutenção da rede de drenagem causando preocupação, pois pode afetar sua dinâmica hídrica, o uso múltiplo das águas e influenciar no pulso de inundação do Pantanal mato-grossense.

Abstract. Organic nitrate esters are key products of terpene
oxidation in the atmosphere. We report here the preparation and purification
of nine nitrate esters derived from (+)-3-carene, limonene, α-pinene, β-pinene and perillic alcohol. The availability of these
compounds will enable detailed investigations into the structure–reactivity
relationships of aerosol formation and processing and will allow individual
investigations into aqueous-phase reactions of organic nitrate esters.

Abstract. Accurate reference spectroscopic information for the water molecule from the microwave to the near-ultraviolet is of paramount importance in atmospheric research. A semi-empirical potential energy surface for the ground electronic state of H216O has been created by refining to almost 4 000 experimentally determined energy levels. These states extend into regions with large values of rotational and vibrational excitation. For all states considered in our refinement procedure, which extend to 37 000 wavenumber and J = 20, the average root mean squared deviation is approximately 0.05 wavenumber. This potential energy surface offers significant improvements when compared to recent models by accurately predicting states possessing high values of J. This feature will offer significant improvements in calculated line positions for high temperature spectra where transitions between high J states become more prominent. Combining this potential with the latest dipole moment surface for water vapor, a line list has been calculated which extends reliably to 37 000 wavenumber. Obtaining reliable results in the ultraviolet is of special importance as it is a challenging spectral region for the water molecule both experimentally and theoretically. Comparisons are made against several experimental sources of cross sections in the near-ultraviolet and discrepancies are observed. In the near-ultraviolet our calculations are in agreement with recent atmospheric retrievals and the upper limit obtained using broad band spectroscopy by Wilson et al. (J. Quant. Spectrosc. Radiat. Transf., 2016, 170, 194) but do not support recent suggestions of very strong absorption in this region.
Differing pre-industrial cooling trends between tree rings and lower-resolution temperature proxies

Published: April 2020

Abstract. The new PAGES2k global compilation of
temperature-sensitive proxies offers an unprecedented opportunity to study
regional to global trends associated with orbitally driven changes in solar
irradiance over the past 2 millennia. Here, we analyze pre-industrial
long-term trends from 1 to 1800 CE across the PAGES2k dataset and find that,
in contrast to the gradual cooling apparent in ice core, marine, and lake
sediment data, tree rings do not exhibit the same decline. To understand why
tree-ring proxies lack any evidence of a significant pre-industrial cooling,
we divide those data by location (high Northern Hemisphere latitudes vs. midlatitudes),
seasonal response (annual vs. summer), detrending method, and temperature
sensitivity (high vs. low). We conclude that the ability of tree-ring
proxies to detect pre-industrial, millennial-long cooling is not affected by
latitude, seasonal sensitivity, or detrending method. Caution is advised
when using multi-proxy approaches to reconstruct long-term temperature
changes over the entire Common Era.
Long-term changes in central European river discharge for 1869–2016: impact of changing snow covers, reservoir constructions and an intensified hydrological cycle
Authors: Rottler Erwin , Francke Till , Bürger Gerd , Bronstert Axel
Published: April 2020

Abstract. Recent climatic changes have the potential to severely alter river runoff, particularly in snow-dominated river basins. Effects of changing snow
covers superimpose with changes in precipitation and anthropogenic modifications of the watershed and river network. In the attempt to identify and
disentangle long-term effects of different mechanisms, we employ a set of analytical tools to extract long-term changes in river runoff at high
resolution. We combine quantile sampling with moving average trend statistics and empirical mode decomposition and apply these tools to discharge
data recorded along rivers with nival, pluvial and mixed flow regimes as well as temperature and precipitation data covering the time frame
1869–2016. With a focus on central Europe, we analyse the long-term impact of snow cover and precipitation changes along with their interaction
with reservoir constructions. Our results show that runoff seasonality of snow-dominated rivers decreases. Runoff increases in winter and spring, while discharge decreases in
summer and at the beginning of autumn. We attribute this redistribution of annual flow mainly to reservoir constructions in the Alpine ridge. During the
course of the last century, large fractions of the Alpine rivers were dammed to produce hydropower. In recent decades, runoff changes induced
by reservoir constructions seem to overlap with changes in snow cover. We suggest that Alpine signals propagate downstream and affect runoff far
outside the Alpine area in river segments with mixed flow regimes. Furthermore, our results hint at more (intense) rainfall in recent
decades. Detected increases in high discharge can be traced back to corresponding changes in precipitation.

O objetivo do presente estudo foi estimar a prevalência e identificar os fatores de risco associados à infecção por Toxoplasma gondii em 103 gestantes atendidas pelo Sistema Único de Saúde, em uma unidade de saúde especializada no município de Curitiba, Paraná. Para isso, foi realizado um estudo epidemiológico transversal quantitativo a partir da realização de entrevistas utilizando um questionário estruturado. As informações referentes à triagem sorológica foram obtidas a partir das cadernetas das gestantes durante a entrevista.  O teste do Qui Quadrado e Exato de Fischer foram utilizados para análise dos dados, e o odds ratio (OR) para estimar a chance de associação entre variáveis de exposição e desfecho. Das 103 gestantes avaliadas, 59 (57,28%) apresentaram anticorpos anti-Toxoplasma gondii e 42,72% eram soronegativas. Houve associação estatisticamente significativa entre as variáveis renda familiar (P = 0,03), tipo de moradia (P = 0,005), consumo de carne crua ou mal cozida e ingestão de frutas e vegetais mal higienizados (p = 0,045). Deste modo, a identificação dos fatores de risco se faz necessária para implantação de medidas de prevenção e controle da toxoplasmose materna e congênita.
The Use of Debates as an Approach to Deliver the Course Entitled “The Impact of US Policy on Integration Processes in Europe in the Post-Bipolar Era”
Authors: Korniienko Alina Yu.
Published: April 2020

The purpose of this research was to identify how the use of a debate-based course delivery approach merged with a flipped classroom model influenced the students’ academic outcomes and motivation in relation to their intelligence type and how the sampled students perceived the course delivery approach and certain debate-related activities. Sampled students’ academic performance records, an evaluation survey to obtain students’ feedback on both the course delivery approach and the effectiveness of the activities like ‘Think-Pair-Share’, ‘Write-Pair-Share’, ‘Illogical story-telling’, ‘Treasure Hunt’, case-study, ‘One Minute Paper’, ‘Attitude/motivation test battery’ as intelligence type-based diagnostics of learners’ motivation, and a focus-group semi-structured interview were used as the instruments. SPSS 10.0.5 computer statistical package was used to process data. The use of debates to deliver the instructional content to the tertiary students can be considered a three-vector approach capable to bring a positive change to learning motivation, cognitive (intellectual) activity, self-esteem (self-efﬁcacy) of a student and the overall quality of the vocational training system of the historians and lawyers-to-be. This study boosts the methodology of vocational training of the students majoring in humanities like History/Law in terms of fostering the 21st century-competencies and it adds a different perspective to the theory on relation between the type of intelligence and skills. This approach fosters learner autonomy and positive perception of challenging educational activities. It was found that it was prerequisite for the success of the above approach that there was a well-trained debate moderator, and debate-procedure-aware and trained students. The further research is needed in purposeful introduction of NLP training into the above model and examination its impacts.

Published: April 2020

Background:

Owing to concerns regarding higher cost, low quality of care and cherry-picking in physician-owned hospitals (POHs), the Affordable Care Act imposed sanctions that prevented the formation of new POHs. With an increasing utilization of total shoulder arthroplasties (TSAs), there is a need for re-evaluation and assessment of quality and cost of TSAs performed at these POHs.

Methods:

The 2011 to 2014 Medicare 100% Standard Analytical Files was used to identify patients undergoing a reverse TSA or anatomic TSA at POHs and non-POHs. Multivariate regression analyses were used to assess differences in 90-day and 1-year outcomes between the two groups.

Results:

A total of 1,626 (2.2%) patients received a TSA at a POH (N = 50). No notable differences were noted between POH versus non-POHs regarding 90-day surgical site infections (P = 0.645), dislocation (P = 0.068), periprosthetic fractures (P = 0.556), revision arthroplasty (P = 0.114), pulmonary embolism (P = 0.155), deep vein thrombosis (P = 0.208), acute myocardial infarction (P = 0.219), sepsis (P = 0.288), urinary tract infections (P = 0.186), all-cause readmissions (P = 0.427), 1-year dislocations (P = 0.475), 1-year periprosthetic fractures (P = 0.697), and 1-year revision arthroplasties (P = 0.225). TSAs performed at POHs had higher odds of postoperative stiffness at 90-day (odds ratio 1.39; P < 0.001) and 1-year follow-up points (odds ratio 1.51; P < 0.001). TSAs at POHs had markedly lower risk–adjusted 90-day charges (−$8,904) and 90-day costs (−$1,659).

Conclusion:

Apart from slightly higher rates of stiffness and renal complications, patients undergoing TSAs at POHs seem to have similar outcomes as compared to non-POHs, while having lower costs of care. The findings suggest a need for further research, evaluating the value of care at POHs.

Published: April 2020

Purpose: With the rapid expansion of the field of interventional neuroradiology (INR) and the diverse background of aspiring neuro-interventionists, there is an ever increasing need to establish consensus criteria for training and accreditation in INR.Materials and Methods: We performed a survey to explore the current state of criteria for training and accreditation in INR. The questionnaire consisting of 11 questions was emailed to the members of World Federation of Interventional and Therapeutic Neuroradiology (WFITN) worldwide. It was focused on the training charter, training program, qualifying examination, and education after training program as perceived by practitioners in each country.Results: A total of 52 WFITN members in 19 countries responded to the questionnaire. There was a huge variation internationally and nationally due to the unique situation and challenges in each country and institution. Criteria for training and accreditation in INR were well established in some countries of Europe, North America, and Asia but not specified in other countries.Conclusion: It is critical to establish consensus criteria for training and accreditation in INR in order to ensure safe practice and continued expansion and development of INR as a specialty.
