Kolekcje trofeów myśliwskich elementem kultury tradycji myśliwskiej
Authors: Sobalak Tomasz
Published: February 2020

Trofea zawsze stanowiły i stanowią ważną część kultury i rytuału myśliwskiego. Jako materialny dowód odniesionego sukcesu świadczą o myśliwskiej sprawności zdobywcy. Pozostawiają w pamięci utrwalony zapis przeżytych wydarzeń podczas łowów.Mogą być przedmiotem chwały i dumy, zwłaszcza jeśli stanowią odpowiednio przygotowane i eksponowane zbiory. Chęć posiadania rzeczy rzadkich i fascynacja nimi leży w naturze ludzkiej od tysiącleci. Na tym tle niezwykle ciekawie przedstawia się historia traktowania i przedstawiania trofeów.Sposoby ich preparowania, eksponowania i konserwacji określają sylwetkę etyczną myśliwego. Kto nie szanuje trofeów, ten nie szanuje zwierzyny, ten po prostu nie powinien polować. Jeśli traktować trofeum, jako symbol życia wyrwanego z kniei, to „tryumf” ten wypada odpowiednio uhonorować. Nie ma przepisów prawnych, jak to robić. Nie ma oficjalnego porządku ani ustalonej urzędowej gradacji ich wartości. Istnieje jednak głęboko zakorzeniona tradycja zbierania i pokazywania trofeów. Gabinety myśliwskie, to pomieszczenia o charakterze szczególnym, wręcz sanktuaria strzegące pasji ich użytkowników. W czasach współczesnych eksponowanie trofeów może być uzależnione od sytuacji finansowej myśliwego, jednak często wymuszony, wielki ścisk na ścianie, wśród ejsmondowskich „klejnotów wspomnień” tworzy swoisty klimat, którego nie można znaleźć nigdzie indziej.
Khoisan – the Best Hunters in the World
Authors: Wawrzyniak Sandra
Published: February 2020

Khoisan or Bushmen, are one of the last hunter-gatherers living on our planet that follow the traditional way of life. They inhabit the remote, harsh environment of the Kalahari and Namib deserts, and are often described as the best hunters in the world. This article presents the outline of their thousands of years old hunting techniques, strategies as well as weapons and traps applied while hunting. It also demonstrates how hunting affects the social and economical structure of their communities. The article also deals with the trends in tourist hunting in South Africa with special regard to the ‘hunting with the Bushmens’ offers.

The PEritoneal SUrface CAlculator (PESUCA): A new tool to quantify the resected peritoneal surface area after cytoreductive surgery
Authors: Schredl Philipp , Ramspott Jan Philipp , Neureiter Daniel , Emmanuel Klaus , Jäger Tarkan
Published: February 2020

Background

The body surface area (BSA) is taken as a measure for the effective contact area for dosing in hyperthermic intraperitoneal chemotherapy (HIPEC). Currently, the pharmacokinetic effect of the reduced peritoneal surface area (PSA) after cytoreductive surgery (CRS) during HIPEC remains unclear. Here a proprietary software solution (PEritoneal SUrface CAlculator (PESUCA)) to quantify the resected PSA in patients with peritoneal surface malignancies (PSM) undergoing CRS and HIPEC is presented.

Methods

The PESUCA tool was programmed as a desktop and online software solution. The applicability was evaluated in 36 patients. The programming-algorithm is briefly summarized as follows: (1) calculation of BSA, (2) correlation to PSA, (3) calculation of the relative proportion of 40 different anatomical regions to total PSA before CRS, (4) instantaneous input of each resected proportion in the 40 anatomical regions during CRS, and (5) determination of the resected and remaining PSA after CRS.

Results

The proof of concept revealed a mean PSA of all patients before CRS of 18,741 ± 321 cm2 compared to 13,611 ± 485 cm2 after CRS (p<0.0001). Patients’ supramesocolic and inframesocolic visceral and parietal peritoneal area before and after CRS procedure were quantitatively determined.

Conclusions

Here the first tool that enables detailed PSA quantification in patients with PSM undergoing CRS is presented. This makes the software a valuable contribution to ensue more accurate assessment and improved comparability of peritoneal disease extent. Furthermore, after external validation, PESUCA could be the basis for dose adjustment of intraperitoneal chemotherapy regimens based on the remaining PSA after CRS.
Design, synthesis, and characterization of 6-[(trimethyl)silylethynyl]naphthalene-2-ethene: a new precursor for the preparation of high-refractive-index organic materials
Authors: Legrand Sacha , Hannu-Kuure Milja , Kärkkäinen Ari
Published: February 2020

A new polymerizable naphthalene derivative has been designed, prepared, and characterized by 1H, 13C NMR, and MS. The new monomer synthesis has successfully been accomplished from a cheap commercially available raw material, in only four steps with good yields. The four steps can be easily scaled up for manufacturing purposes. It is anticipated that the new precursor can be very useful in the preparation of valuable materials with high refractive index for numerous opto-electronic applications.
Water Sovereignty in the Age of Global Capitalism
Authors: Schneider Matthew
Published: February 2020

This paper discusses the process of “accumulation by dispossession” of water resources by the institutions of the transnational state and the role of nationalism in the resulting movement for reappropriation. A comparative analysis of Latin American countries is conducted using data obtained from UN databases and historical accounts. The object of this analysis is to delineate a causal pathway surrounding the dynamics of water sovereignty in the age of global capitalism. I find that privatization is not likely to occur if there is a lack of crisis or there is a socialist executive; however, if privatization does occur, and the appropriating action is taken by a multinational corporation, activated nationalist sentiment may lead to reappropriation of water resources.
Corrección de una maloclusión Clase III de Angle en paciente adulto con la técnica Multiloop Edgewise Archwire con un control post tratamiento de 1 año
Authors: Valdez Galdos Mariana , Fernandez Rivas Armando
Published: February 2020

Tradicionalmente el tratamiento de la compensación, el camuflaje, de las maloclusiones de Clase III, ha estado orientado a la extracción de primeros premolares inferiores, distalización de caninos y lingualización de incisivos inferiores con la finalidad de obtener un overbite y overjet aceptables. El propósito de este reporte es describir el diagnóstico y plan de tratamiento de una maloclusión Clase III, en un paciente adulto, soportado por una revisión bibliográfica. El caso fue tratado con el sistema Multiloop Edgewise Arch Wire (MEAW) y se realizaron exodoncias de terceros molares inferiores. El sistema MEAW utiliza arcos con dobleces colocados en los espacios dentarios interproximales, desde la parte distal de los incisivos laterales hasta la última pieza en el sector posterior, al cual se le realizan ciertas activaciones según la maloclusión. Se puede concluir, que con este sistema es posible compensar los casos de Clase III mediante la reconstrucción del plano oclusal, evitando así el realizar exodoncias de premolares inferiores. Además, controlando el efecto de lingualización de los incisivos inferiores se genera un correcto overjet y overbite y relaciones caninas Clase I.

Published: February 2020

El estudio tuvo como objetivo determinar el efecto de la ratio energía / proteína de las raciones alimenticias suplementarias (RAS) sobre la producción y características de la leche en condiciones hipobáricas naturales (4300 m de altitud en Puno, Perú). Se distribuyeron al azar 24 vacas Brown Swiss de primer y segundo tercio de lactación en tres RAS con tres ratios de energía metabolizable / proteína (RAS1: 17.0 kcal/g; RAS2: 14.2 kcal/g; RAS3: 12.4 kcal/g) y como fuente de proteína tres niveles de harina hidrolizada de pieles de ovino y alpaca – Pioval-2® (0, 3 y 6%, respectivamente) y tres niveles de harina de soya integral extruida (0, 10 y 25%, respectivamente). Las vacas estaban al pastoreo sobre cultivo de alfalfa asociado a rye grass y recibieron ensilado de avena. Se determinó la producción diaria de leche (PDL) durante 45 días, así como la densidad (DE), sólidos totales (ST), grasa (GR) y nitrógeno ureico en la leche (NUL) a los 0, 15, 30 y 45 días. Las RAS no afectaron la PDL (17.7, 18.8 y 19.0 kg/día) ni la DE (1,031, 1,031 y 1,030 g/l, respectivamente) de la leche. La RAS2 incrementó los ST y GR (13.0%, 4.2%) con relación a RAS1 (12.4%, 3.8%) y RAS3: 12.2%, 3.9%) (p<0.01) en la leche, respectivamente. Con la disminución de la fracción energía / proteína en las raciones el NUL aumentó proporcionalmente (RAS1: 28.9; RAS2: 32.3; RAS3: 36.8 mg/dl; p<0.001). En conclusión, el aumento de la fracción energía / proteína de la ración de concentrado no afectó la producción ni la densidad de la leche, pero mejoró el contenido de sólidos totales y grasa; mientras que la reducción de la ratio energía / proteína en la ración incrementó consistentemente el nitrógeno ureico en la leche.

El objetivo del estudio fue evaluar la expresión relativa de las citoquinas involucradas en la respuesta inmune Th1 (IL-2, IL-12, IFN-γ, TNF-α), Th2 (IL-4, IL-10 y TGF-β) y Th17 (IL-17) en 21 cuyes (Cavia porcellus) inoculados experimentalmente con una cepa aislada de campo de Salmonella Typhimurium a una dosis de 102 UFC/ml, vía intraperitoneal, y comparados con un grupo control de siete cuyes (inoculados con una cepa tratada térmicamente). Se tomaron muestras de sangre los días 1, 3, 5, 7, 9, 15 y 30 pos-inoculación (p.i.). Se extrajo el ARN total de las células linfocitarias y se desarrolló la RT-PCR en tiempo real usando cebadores específicos para las citoquinas. La expresión relativa fue determinada por el método comparativo 2-ΔΔCt a fin de evaluar la expresión de los ARNm de las citoquinas respecto al calibrador (cuy sano), y usando como gen constitutivo de referencia al GAPDH como normalizador. Las expresiones de los genes de las citoquinas en el grupo Tratamiento mostraron un aumento con respecto al grupo Control y una cinética ascendente con respecto a los días p.i. Los primeros días hubo predominio de las expresiones Th1 sobre Th2, posteriormente ambos aumentaron, con predominio de IL-4 e IL-17 a partir del día 15 p.i. La inoculación de S. Typhimurium estimuló una expresión mayoritaria de IL-12 respecto a las otras citocinas, lo cual induciría en los cuyes una respuesta de tipo celular o Th1.

Published: February 2020

El objetivo de este trabajo fue identificar los antígenos receptores de angiotensina II en la arteria umbilical de la alpaca (Vicugna pacos). Se trabajó con seis úteros grávidos de alpacas procedentes de comunidades alpaqueras a 4000 msnm en Cusco, Perú, cuyo tiempo de gestación fue estimado por el diámetro biparietal del feto. Se obtuvieron cortes histológicos de 5 µm de espesor de cada arteria umbilical. Se aplicó la técnica de inmunohistoquímica (IHQ) Avidina-Biotina-peroxidasa, utilizando reactivos de IHQ y anticuerpos policlonales anti-Angiotensina II. Las láminas fueron analizadas con microscopio binocular Leica DM750 con cámara digital anexada y software LAS 4.7 Leica Macrosystems. La intensidad de marcación se clasificó de manera cualitativa (0: sin marcación; 1: marcación leve; 2: marcación moderada; 3: marcación fuerte). Para el control positivo se empleó muestras de arteria umbilical ovina. Los antígenos receptores de angiotensina II se localizaron en las células musculares lisas de las arterias umbilicales en los tiempos de gestación evaluados. Los antígenos presentaron una intensidad de marcación fuerte, lo que demuestra que la angiotensina ejerce su actividad biológica de vasoconstricción en las células musculares lisas del vaso sanguíneo.

La regresión logística indicó que los factores relacionados al mayor éxito de la preñez fueron la calidad del embrión (grado 1 y 2), la raza de la donadora (Huacaya) y la CC de la receptora (grado 2 y 3).
Tecnología de los quesos bajos en grasa
Authors: Mayta-Hancco Jhony , Trujillo Antonio-José , Juan Bibiana
Published: February 2020

Los quesos bajos en grasa se caracterizan por tener deficiencias en el sabor, textura y propiedades funcionales debido al alto contenido de humedad y proteína. Algunas estrategias desarrolladas para mejorar estas deficiencias incluyen el uso de cultivos adjuntos, uso de sustitutos de grasa y técnicas de procesado. El uso de cultivos adjuntos (principalmente Lactobacillus spp) pueden mejorar la funcionalidad y el sabor de los quesos bajos en grasa. Es deseable contar con cultivos de baja actividad proteolítica, pero de alta actividad peptidolítica (para evitar la formación excesiva de ácidos y sabores amargos). El uso de estabilizadores, sustitutos y miméticos de grasa (base proteína y carbohidratos) también se ha empleado para mejorar la calidad de los quesos bajos en grasa. Las técnicas de procesado, tales como los procesos de membrana (ultrafiltración y microfiltración), suplementación de la leche con proteínas de suero, adición directa de suero de mantequilla, estandarización de la leche en términos de caseína/grasa y la homogeneización han sido utilizadas para mejorar la textura, rendimiento y propiedades funcionales de los quesos bajos en grasa.

Published: February 2020

In this paper we had made an attempt to incorporate the results from the theory of square Gaussian random variables in order to construct the goodness of fits test for random sequences (time series). We considered two versions of such tests. The first one was designed for testing the adequacy of the hypotheses on expectation and covariance function of univariate non-centered sequence, the other one was constructed for testing the hypotheses on covariance of the multivariate centered sequence. The simulation results illustrate the behavior of these tests in some particular cases.

Published: February 2020

Unfavorable general demographic indicators are to a large extent predetermined by a demographic situation in some population groups. Therefore, in order to achieve a more sustainable demographic development at the country level and develop an adequate response from relevant population policies, it is necessary to measure the scale of demographic differentiation and identify population groups at risk. This requires reliable population-level data and innovative methods for measuring demographic differentials. The main aim of this work is to present advantages and capabilities of methodology for development of census-linked databases based on the linkages between census and demographic records. This study provides selected empirical examples and new scientific data on socio-economic and socio-demographic differences in mortality, first divorces, and births in Lithuania. These data can be further used for improving population policies in Lithuania and performing comparative analyses with other countries.

The goal of this paper is to analyze the tendencies of social exclusion and inequality in Lithuania and in the context of Europe. By using statistical methods such as Gini coeﬃcient and Lorenz curve, ﬁrstly we analyze the inequality of average county disposable household income per month. In the second part of the study, we analyze an indicator of people at-risk-of poverty or social exclusion in 26 diﬀerent countries of Europe. In this section, we want to test the ﬁxed and random eﬀects models on our data. Based on them, the average eﬀect of the at-risk-of poverty or social exclusion indicator can be measured. Based on real expenditure per capita analysis, Lithuania can be classiﬁed to a group of post-Soviet countries, where tendencies of poverty or social exclusion risk are similar.

Estimation of the Number of Unemployed and Employed For Lithuanian Counties and Municipalities Using Models
Authors: Naujanis Linas , Krapavickaitė Danutė
Published: February 2020

Problems of finite population parameters estimation are analyzed in this paper. Four methods have been used for parameterestimation: sampling design-based unbiased estimator, multiple regression and logistic regression model-based estimators and James–Stein estimator. The design-based estimator is unbiased, but its standard deviation is usually high. Model-based estimators are notunbiased, but their standard deviations are low. In order to minimize the standard deviation and the bias, the James–Stein estimator isapplied. Labour force survey data of Statistics Lithuania are used for simulation to study model-based estimators for the number ofunemployed and employed persons in districts and counties, and the role of information on registered unemployment in these models.
Modeling and Forecasting Exchange Rates
Authors: Gudan Jovita
Published: February 2020

This paper investigates models for the euro exchange rate against the currencies of Denmark, Poland, theUnited States, and the United Kingdom. The objective of this paper is to compare different methods of modeling andout-of-sample forecasting. One of the techniques is cointegration relation, which is implemented through a vector errorcorrection model. The existence of cointegration supports the long-run relationship between the nominal exchange rateand a number of fundamental variables. The evidence presented in this paper shows that a simple multivariate randomwalk model tends to have superior predictive performance, compared to other exchange rate models, for a period of lessthan one year.

A scoping review of simulation-based dental education
Authors: Higgins Denise , Hayes Melanie , Taylor Jane , Wallace Janet
Published: February 2020

This article was migrated. The article was marked as recommended. In order to meet the needs of student learning within a competency-based pedagogy, it is necessary to understand the current philosophies and modalities being used in dental and oral health simulation-based education. The aim of this literature review is to identify the existing research relating to the educational structure of dental and oral health simulation activities. The review is presented as a scoping review, formulated and conducted using a modified five stage methodological framework. Despite evidence showing that the healthcare simulation model is ideal for learning and assessments of non-clinical and clinical tasks such as psychomotor skills, there is a paucity of published literature relating to simulation in dental and oral health education. Out of 72 initial articles only six papers related to dental preclinical psychomotor skills in an educational setting, none of which were deemed high-quality. Deficiencies in these papers included no statements defining underpinning educational theory, limited acknowledgement of evidence-based simulation activities including preparation, briefing, simulation, feedback, debriefing, reflection and evaluation. Given the widespread use of simulation in dentistry, academics should be encouraged to publish their scholarly activities in simulation-based dental education in order so that all dental faculties can work towards developing contemporary simulation curriculum to provide optimum teaching and learning opportunities for students.

Published: February 2020

This paper presents the assessment of consolidation and creep settlements of an isolated circular footing supported on soft clay samples reinforced with a single granular column. Clay samples (300 mm dia., 400 mm high) were formed from reconstituted kaolin and remoulded sleech (exhibiting significant creep). These samples were tested using chambers with various features to capture the settlement under constant foundation loading. In one model, the footing (70 mm dia.) was supported by a 40 mm dia. granular column formed by crushed basalt. The footings, with and without a granular column, were subjected to five vertical loading increments: 60, 120, 180, 240 and 300 kPa in the case of kaolin. In the case of sleech, vertical loading increments were: 60, 120 and 180 kPa. Each test lasted approximately ten months. In the case of kaolin, the settlement reduction factor was marginal, although it was considerably better for sleech. Kaolin exhibited marginal creep settlement under low to moderate bearing pressure, which increased substantially under high bearing pressures. Creep settlement was more prominent in sleech at all levels of bearing pressures. The very interesting finding from the investigation is that the settlement reduction factors due to consolidation and creep are similar in order under low to moderate loadings.
Students’ perspectives on English medium instruction within higher education
Authors: Bukve Trude
Published: February 2020

This study aims to explore gender differences in students’ perspectives on language use within higher education (HE), using data from a survey distributed to students at two universities in Norway and Finland. Analysing responses concerning language use in HE, I found that most students were positively inclined towards English medium instruction (EMI). However, while there in both countries were only small differences in attitudes towards EMI between male and female students, in Finland, female students were less confident in their English skills than male students were. Furthermore, female students in both countries reported more difficulties in coping with English in their day-to-day studies, as compared to male students. This article demonstrates the advantages of applying a multidimensional perspective when analysing gendered attitudes in HE. Further, the present study highlights some of the practical challenges that HE institutions should acknowledge in order to implement language policies that meet students’ needs.
An overlooked family-group name among bees: Availability of Coelioxoidini (Hymenoptera: Apidae)
Authors: Engel Michael S. , Gonzalez Victor , Rasmussen Claus
Published: February 2020

Recent phylogenetic analysis of the family Apidae has applied the tribal name Coelioxoidini to the distinctive genus Coelioxoides Cresson, which has been thought to be related to Tetrapedia Klug.  However, the nomenclatural status of such a family-group name has not yet been assessed.  Herein, we determine that this family-group name is available and discuss its authorship and proposal date.

Authors: Alave Mamani Sislay Marcia , Pampa Yupanqui Sara Nelbith
Published: February 2020

El presente estudio describe la relación entre la dependencia a los videojuegos y las habilidades sociales en los estudiantes de una Institución Educativa estatal de Lima-este. La muestra se compuso de 375 adolescentes de ambos sexos en dicho centro educativo. Como instrumentos se utilizó el Test de dependencia a videojuegos de Marcos y Cholíz (2012) y la Escala de Habilidades Sociales (EHS) de Goldstein (1978), adaptada en el Perú por Ambrosio Tomás en 1995. Los resultados de la investigación revelan una correlación débil, negativa y significativa entre la dependencia a videojuegos y las habilidades sociales en general (rho= -.132 p<0.05); por otro lado, se encontró una relación significativa en las dimensiones de “habilidades alternativas a la agresión” (rho= -.209; p<0.05) y “habilidades relacionadas con el estrés”        (rho= -.108; p<0.05). En suma, mientras se presenten niveles bajos de dependencia a videojuegos existirán más recursos para relacionarse adecuadamente o viceversa.

Objective

Wellness is a challenge for Indigenous peoples, partly because Western services do not adopt a holistic approach. By devaluing traditional knowledge, Indigenous values and beliefs, these services lower Indigenous power and affect cultural identities. Indigenous elders participate in intergenerational solidarity by transmitting knowledge, values, and culture in a holistic approach. Despite widespread acceptance of the importance of Indigenous elders’ contributions to wellness, a rigorous synthesis of knowledge has never been done. This study aimed to provide a comprehensive understanding of how Indigenous elders’ social participation contributes to individual and community wellness.

Method

A scoping review was conducted with Indigenous elders and stakeholders in Québec (Canada). Sixteen databases were searched with 57 keywords. Data from the documents retrieved were analyzed, organized, and synthesized based on the International Classification of Functioning, Disability and Health.

Synthesis

A total of 144 documents were examined, comprising 74 scientific papers and 70 sources from the gray literature. Indigenous elders contributed to wellness mainly through relationships and interactions with other community members and non-Indigenous people (72.2%); intergenerational oral and written communications (70.1%); community, social and civic life (45.8%); volunteering and jobs (35.4%); and family life (29.9%). Elders transmit traditional knowledge, strengthen social cohesion, and help to develop positive attitudes such as reciprocity. Their actions favour disease prevention and health promotion, as including traditional approaches increases the acceptability of health and social services.

Conclusion

This scoping review highlights the need for longitudinal studies with mixed-method designs involving Indigenous communities at all stages of the research to deepen understanding of the contributions of Indigenous elders to individual and community wellness.
Place Narratives and the Experience of Class: Comparing Collective Destigmatization Strategies in Two Social Housing Neighborhoods
Authors: Junnilainen Lotta
Published: February 2020

A growing body of literature has investigated the various ways in which residents of stigmatized neighborhoods respond to and cope with stigmatization. However, these approaches have fallen short in tackling the question of how particular places shape responses to stigmatization. In this article, I take seriously the question of context and, based on a comparative ethnography of two social housing neighborhoods in Finland, show how residents in similar social structural positions differed in terms of the cultural milieus they inhabited, presenting them with different cultural resources for dealing with stigmatization. In the article, I suggest that non-recognition is an understudied but significant consequence of stigma related to social housing neighborhoods. Further, I suggest that depending on the historical and cultural context of the neighborhood, different destigmatization strategies are employed when residents face non-recognition. My data shows that locally lived collective place narratives informed residents’ experiences of class: In one neighborhood, the defining element of the locally acknowledged place narrative was class struggle, whereas in the other it was middle-class aspiration. These narratives served as building blocks for their destigmatization strategies.
Housing Stigmatization: A General Theory
Authors: Horgan Mervyn
Published: February 2020

This article treats housing stigmatization as a social process of symbolic ascription, connected to inhabitants, housing form, housing tenure, and/or housing location. Stigmatization research tends to focus on personal stigmatization, or to examine housing only in relation to territorial stigmatization, while housing research tends to focus on health and policy. This article demonstrates that housing stigmatization, which is differentiated from personal stigmatization and territorial stigmatization, is a viable unit of analysis in its own right for stigma research. Seven core elements are identified, showing that housing stigmatization is: (1) relational; (2) contextual; (3) processual; (4) reinforceable; (5) reversible; (6) morally loaded; and (7) treated as contagious. Comprehending the elements of housing stigmatization will benefit destigmatization efforts.

Tribalism in a Pediatric Emergency Department
Authors: Faro Elissa Z. , Bauman Laurie J.
Published: February 2020

This ethnography explored the organizational culture of a busy urban pediatric emergency department (ED) in the United States. EDs uniquely combine extreme patient acuity, high census, a high-stress unpredictable environment, and fast-paced complex communication. We found that tribalism characterized the organizational culture and was exacerbated by resource scarcity, changing leadership, and high patient volume. Tribalism affected work climate and job satisfaction but is entrenched and difficult to change. We examine the historical, social, and institutional factors that contributed to tribalism and the ways in which tribalism characterized how providers and staff perceived and recreated interprofessional dynamics. This study contributes to existing work on tribalism in health care by looking at factors that impact perceptions of “us vs. them” and ways tribalism was manifested in the day-to-day practice of team-based care.

Authors: Ganiga Pradeep , Subhash Vivek V.
Published: February 2020

Background: Gestational diabetes is defined as impaired glucose tolerance with onset or first recognition during pregnancy. Undiagnosed or inadequately treated gestational diabetes can lead to significant maternal and fetal complications. Even though there are guidelines for diagnosis of GDM (gestational diabetes mellitus) by the Government of India, there is poor penetration of the implementation throughout the nation.Methods: The study was conducted in A. J. Institute of Medical Sciences between April to June 2019. 56 patients were evaluated with the fetal medicine foundation GDM risk calculator to assess the risk for gestational diabetes in a retrospective approach.Results: Incidence of GDM in the study was 15.9%. At a cut-off of 1/80, the calculator predicted increased risk for 37 out of 56 patients. There was a sensitivity of 91.6% and specificity of 63.6% with a negative predictive value of 96.5% and positive predictive value of 29.5%. there was a false positive rate of 43.2%.Conclusions: The fetal medicine foundation GDM risk calculator will prove to be an invaluable tool to predict high risk patients who need closer monitoring of blood glucose into the third trimester.

Authors: Juneja Sunil Kumar , Tandon Pooja , Kaur Gagandeep
Published: February 2020

Background: Uterine artery arteriovenous malformations are an abnormal and non-functional connection between the uterine arteries and veins. It may be congenital or acquired. AVM can cause heavy menstrual bleeding and may have an impact on infertility. Uterine artery embolization is an alternate method to hysterectomy preserving the menstrual and reproductive function. Objectives of this study was to diagnose Arterio-venous malformations after abortions in patients with heavy menstrual bleeding and treating these patients with UAE.Methods: The retrospective study of patients with postabortal arteriovenous malformations managed at Dayanand Medical College and Hospital, during January 2012 to December 2018 was done. Inclusion criteria for this study post abortal heavy menstrual bleeding patients in reproductive age group diagnosed to be having AV malformations on CT angiography. Exclusion criteria for this study were H/O AUB prior to abortion, patients with fibroids, PID, endometriosis, adenomyosis, genital tract malignancies. Patients who do not have AV malformations on CT angiography.Results: This is a retrospective seven years study between January 2012 to December 2018 during which we received 23 patients who developed arterio-venous fistula following an abortion. The patients had heavy menstrual bleeding. All the patients had taken some hormonal treatment before reporting to us. All these patients underwent CT angiography. After that they all were subjected to UAE. All these patients were followed up to 6 months where they showed improvement in the symptoms.Conclusions: Acquired AVM is rare disorder following an abortion or a caesarean section. Heavy menstrual bleeding is a common symptom often requiring hysterectomy but with the advent of uterine artery embolization by blocking the uterine artery we can conserve the uterus where a lady can have normal menstrual and reproductive functions.
