Published: May 2018

Abstract. The forecasted groundwater resource depletion under future climatic conditions will greatly influence subsurface groundwater dependent ecosystems and their associated vegetation. In the Mediterranean region this will create harsh conditions for the maintenance of agroforestry systems dependent on groundwater, such as cork oak woodlands. The threat of increasing aridity conditions will affect their productivity and eventually induce a shift in their geographical distribution. Thus, characterizing and modelling the relationship between environmental conditions and subsurface groundwater dependent vegetation (subsurface GDV) will allow to identify the main drivers controlling its distribution and predict future impacts of climate change. In this study, we built a model that explains subsurface GDV distribution in southern Portugal from climatic, hydrological and topographic environmental variables. To achieve this, we relied on the density of Quercus suber, Quercus ilex and Pinus pinea as proxy species of subsurface GDV. Model fitting was performed between the proxy species Kernel density and the selected environmental predictors using (1) a simple linear model and (2) a Geographically Weighted Regression (GWR), to account for auto-correlation of the spatial data and residuals. When comparing the results of both models, the GWR modelling results showed improved goodness of fitting, as opposed to the simple linear model. Soil type was the main driver of subsurface GDV density closely followed by the aridity index. Groundwater depth did not appear to be as pertinent in the model as initially expected. Model predictor coefficients were used as weighting factors for multicriteria analysis, to create a suitability map to the subsurface GDV in southern Portugal. A validation of the resulting map was performed using independent data of integrated potential distribution of each proxy tree species in the region and overall, there was an accordance between areas of good suitability to subsurface GDV. The model was considered reliable to predict the distribution of the studied vegetation, however, lack of data quality and information was shown to be the main cause for suitability discrepancies between maps. Our new methodology on mapping of subsurface GDV's will allow to predict the evolution of the distribution of subsurface GDV according to climate change scenarios and aid stakeholder decision-making concerning priority areas of water resources management.

Abstract. Heavy precipitation on the south side of the central Alps produced a catastrophic flood in October 1868. We assess the damage and societal impacts, as well as the atmospheric and hydrological drivers using documentary evidence, observations, and novel numerical weather and runoff simulations. The greatest damage was concentrated close to the Alpine divide and Lago Maggiore. An atmospheric reanalysis emphasizes the repeated occurrence of streamers of high potential vorticity as precursors of heavy precipitation. Dynamical downscaling indicates high freezing levels (4000 m a.s.l.), extreme precipitation rates (max. 270 mm/24 h), and weather dynamics that agree well with observed precipitation and damage, and with existing concepts of forced low-level convergence, mid-level uplift and iterative northeastward propagation of convective cells. Simulated and observed peak levels of Lago Maggiore differ by 2 m, possibly because the exact cross-section of the lake outflow is unknown. The extreme response of Lago Maggiore cannot be attributed to low forest cover. Nevertheless, such a paradigm was adopted by policy makers following the 1868 flood, and used to implement nationwide afforestation policies and hydraulic structures. These findings illustrate the potential of high-resolution, hydro-meteorological models – strongly supported by historical methods – to shed new light on weather events and their socio-economic implications in the 19th century.

Published: May 2018

Abstract. Ice properties inferred from multi-polarization measurements, such as birefringence and crystal orientation fabric (COF), can provide insight into ice strain, viscosity and ice flow. In 2008, the Center for Remote Sensing of Ice Sheets (CReSIS) used a ground-based VHF radar to take multi-channel and multi-polarization measurements around the NEEM (North Greenland Eemian Ice Drilling) site. The system operated with 30  MHz bandwidth at a center frequency of 150 MHz. This paper describes the radar system, antenna configurations, data collection, and processing and analysis of this data set. In the area of 100 km^2 around the ice core site, ice birefringence dominates the power variation patterns of co-polarization and cross-polarization measurements. The phase shift between the ordinary and extraordinary waves increases nonlinearly with depth. The ice optic axis lies in planes that are close to the vertical plane and perpendicular or parallel to the ice divide depending on depth. The ice optic axis has an average tilt angle of about 11.6° vertically, and its plane may rotate either clockwise or counterclockwise by about 10° across the 100-km^2 area, and at a specific location the plane may rotate slightly counterclockwise as depth increases. Comparisons between the radar observations, simulations, and ice core fabric data are in very good agreement.
Control design, implementation and evaluation for an in-field 500 kW wind turbine with a fixed-displacement hydraulic drivetrain
Authors: Mulders Sebastiaan Paul , Diepeveen Niels Frederik Boudewijn , van Wingerden Jan-Willem
Published: May 2018

Abstract. The business case for compact hydraulic wind turbine drivetrains is becoming ever stronger, as offshore wind turbines are getting larger in terms of size and power output. Hydraulic transmissions are generally employed in high load systems, and form an opportunity for application in multi-megawatt turbines. The Delft Offshore Turbine (DOT) is a hydraulic wind turbine concept replacing conventional drivetrain components with a single seawater pump. Pressurized seawater is directed to a combined Pelton-generator combination on a central multi-megawatt electricity generation platform. This paper presents the control design, implementation and evaluation for an intermediate version of the ideal DOT concept: an in-field 500 kW hydraulic wind turbine. It is shown that the overall drivetrain efficiency and controllability is increased by operating the rotor at maximum rotor torque in the below-rated region using a passive torque control strategy. An active valve control scheme is employed and evaluated in near-rated conditions.
Enfoques mediáticos sobre libertad y seguridad. La Ley española de Seguridad Ciudadana como estudio de caso
Authors: Durán Rafael
Published: May 2018

Durante la legislatura española 2011/2014 se reformó la ley de seguridad ciudadana, popularmente conocida como ley mordaza. A favor y en contra se esgrimieron argumentos relativos a la libertad y la seguridad garantizada o amenazada, según el punto de vista. En este análisis de contenido se estudian los enfoques mediáticos a que fue expuesta la ciudadanía a la hora de informarse al respecto. Para ello se ha analizado la cobertura del proceso legislativo por los ocho periódicos de información general con más lectores diarios. Se concluye 1) que la crítica a la reforma, por restrictiva y aun represiva, no solo no fue marginada del discurso mediático, sino que de hecho tuvo algo más de presencia en el cómputo global; 2) que solo en los medios de derecha primó el enfoque securitario; 3) que la presencia de los dos enfoques estuvo más equilibrada cuanto más alejados de los extremos ideológicos, y 4) que el patrón general se mantuvo estable a lo largo de todo el período.
Neo-gerencialismo y austeridad en el contexto académico español y europeo. ¿Dos caras de la misma moneda?
Authors: Conesa Carpintero Ester , González Ramos Ana M.
Published: May 2018

El personal académico viene afrontando situaciones de vulnerabilidad y precariedad en el contexto español y europeo. Por un lado, la situación de crisis proporciona una justificación a los recortes en financiación para ciencia y universidades; por otro, la dinámica neo-gerencialista produce nuevas condiciones simbólicas y materiales basadas en la competitividad en la academia, previamente a la crisis. Este artículo aporta evidencias acerca de la situación laboral del profesorado universitario español en relación a ambas dinámicas, y analiza algunas diferencias de género. Para ello, en primer lugar, examinamos la dinámica neo-gerencialista y la dinámica de austeridad en el contexto académico europeo y español. En segundo lugar, mostramos la evolución numérica del profesorado en las universidades públicas españolas durante la última década, mediante un análisis de fuentes secundarias públicas distinguiendo categorías laborales y sexo. Los resultados muestran el descenso del personal funcionario (mayormente hombres) y el incremento del personal laboral con anterioridad a la implementación de las medidas de austeridad. Se mantiene un alto número de profesorado asociado apoyando una gran carga docente. El número de mujeres aumenta muy lentamente, estrechando la brecha de género en las etapas iniciales y medianas de las carreras académicas. En conclusión, las políticas de austeridad justifican y facilitan una implementación más rápida del modelo neoliberal de ciencia en España.
“Sentir el cuerpo”: subjetividad y política en la sociedad de masas en España (1890-1931)
Authors: Arbaiza Mercedes
Published: May 2018

El artículo reflexiona sobre las condiciones de aparición de los sujetos en la acción política asumiendo la centralidad del cuerpo como categoría de análisis. Partimos de la hipótesis de que el lenguaje de la política necesita un cuerpo en el que materializarse. Hay dos partes muy marcadas. En la primera, de carácter teórico, se repasan algunos hitos en la renovación del concepto de cuerpo y sus consecuencias en la conformación de la subjetividad. Se propone un concepto spinozista de cuerpo entendiendo este como espacio afectado en el que las emociones se materializan y, a la vez, como espacio activo en la producción del significado. En la segunda parte, se analiza un estudio de caso. La tesis es que la autoconciencia de "degeneración nacional" que envuelve el ambiente político de finales del s. XIX en España se conformó sobre el miedo al cuerpo contaminado, la difusión de la sensación del asco, así como la vergüenza y el estigma de la pobreza. Fueron emociones que modelaron los cuerpos políticos de la sociedad de masas del s. XX. Por lo tanto, la idea que recorre el análisis es que la conciencia de la diferencia social aconteció sobre cuerpos "biológicamente" marcados como "contaminados" y, por consiguiente, “inmorales” y “degenerados”. Más concretamente, el movimiento socialista que irrumpe como movimiento de masas en 1890 es el resultado de la politización de un cuerpo abyecto, el cuerpo obrero, como instancia receptora de signos y creadora de nuevos significados.
La estrategia biográfica. Gertrudis Gómez de Avellaneda y Carolina Coronado, románticas después del romanticismo
Authors: Burguera Mónica
Published: May 2018

Este artículo explora las posibilidades abiertas por la denominada “nueva biografía” como estrategia analítica y narrativa extraordinariamente útil, no sólo para explicar la formación de la subjetividad moderna, sino, también, para iluminar más amplios problemas y periodos históricos. En primer lugar, se hace un recorrido por los contextos historiográficos en los que tuvo lugar el denominado “retorno del sujeto” a través de los debates entre la historia social y la nueva historia cultural, que tendieron a consolidar un cierto determinismo cultural en el que la propia idea de la subjetividad, paradójicamente, se ha cuestionado profundamente. En este contexto, la “nueva biografía,” tal y como se ha ido consolidando desde las últimas décadas del siglo XX, no sólo surgió a través de tensiones analíticas que afectan a la relación entre individuo y sociedad, acción y estructura o texto y contexto, sino, también, a la posibilidad misma de reconstruir los sujetos históricos detrás de los textos y las estructuras discursivas. En segundo lugar, me detengo en el análisis de la vida y la obra de Gertrudis Gómez de Avellaneda y Carolina Coronado precisamente para ilustrar la capacidad de la biografía, no sólo para desentrañar las complejas dinámicas en las que se construye históricamente la subjetividad (femenina), sino, también, para cuestionar los relatos históricos tradicionales.

Authors: Abad Segura Emilio , Valls Martínez Mª del Carmen
Published: May 2018

La Banca Ética es la respuesta a décadas de especulación financiera y a inversiones alejadas de un compromiso ético y cooperativo por parte de la banca tradicional. Constituye el instrumento necesario para gestionar el negocio bancario desde la transparencia, con códigos sociales y medioambientales, sin olvidar la rentabilidad económica para resistir y permanecer en un sistema financiero exigente. El presente trabajo tiene como objetivos, por un lado, estudiar el origen y las características de la banca ética, que aunque no es ajena a los momentos de contracción económica, su misión posibilita que sea una alternativa a la dependencia del sector bancario tradicional; y, por otro lado, examinar las condiciones e iniciativas que la entidad Triodos Bank realiza para posicionarse como banco líder con valores éticos y, a su vez, comparar sus resultados con los obtenidos por las principales entidades financieras de la banca convencional.

Distribution of Alternaria species among sections. 4. Species formerly assigned to genus Nimbya
Authors: Gannibal Philipp B.
Published: May 2018

Morphological examination of phylogenetically unexamined species of the superseded genus Nimbya have permitted the inclusion of additional species in Alternaria sect. Nimbya (two species from monocots), A. sect. Alternantherae (two species from
Amaranthaceae), and A. sect. Porri (one species from Asteraceae). Four other Nimbya species should be considered as taxa that are not distinguishable as unique within A. sect. Alternaria. Alternaria sect. Alternantherae now includes
six species, A. sect. Nimbya includes six species, and A. sect. Porri consists of 118 morphospecies. To bring their nomenclature into accordance with modern Alternaria taxonomy, five new combinations and two replacement names are proposed for seven species
previously accommodated in Nimbya.

Suspended Crisis in Arab-American and Arabic Literatures: Modernity, Violence, and Afflicted Textuality
Authors: Yacoubi Youssef
Published: May 2018

Through a comparative and poststructuralist reading, I will examine the artistic manners in which a selection of Arab-American and Arabic literary texts builds a strategy of a poetics-of-suspended-crisis. By conceptualizing crisis through the discourse of violence, I examine three of its dimensions: crisis as a matter of discursive silencing and silence; crisis as a problem of structure in orientalism, and finally crisis as a textual event, which ultimately announces the detonation of silencing and silence. On this account, I distinguish between two modes of representation of crisis. The first concerns itself with narrating the repository of discursive censures over crises in the Middle East, and therefore aims to depoliticize the silences built over crisis. The second mode exemplifies a trend of inscribing crisis as an antagonistic condition of the text and language itself. My argument pays attention to some of the most esoteric and visceral literary strategies that may have remained repressed in Western frameworks of reading “world” or “ethnic” literatures. My selection of these texts is but a small sample concerned with aestheticizing violence as a fundamental mode of imagining crisis in order to allow new counterpoints of thinking it differently outside modern visions of apocalypse, paralysis, and psychosis.
Automating Electronic Clinical Data Capture for Quality Improvement and Research:

Background: The availability of high fidelity electronic health record (EHR) data
is a hallmark of the learning health care system. Washington State’s Surgical Care
Outcomes and Assessment Program (SCOAP) is a network of hospitals participating in
quality improvement (QI) registries wherein data are manually abstracted from EHRs. To
create the Comparative Effectiveness Research and Translation Network (CERTAIN), we
semi-automated SCOAP data abstraction using a centralized federated data model, created
a central data repository (CDR), and assessed whether these data could be used as real
world evidence for QI and research.Objectives: Describe the validation processes and
complexities involved and lessons learned.Methods: Investigators installed a commercial
CDR to retrieve and store data from disparate EHRs. Manual and automated abstraction
systems were conducted in parallel (10/2012-7/2013) and validated in three phases using
the EHR as the gold standard: 1) ingestion, 2) standardization, and 3) concordance of
automated versus manually abstracted cases. Information retrieval statistics were
calculated.Results: Four unaffiliated health systems provided data. Between 6 and 15
percent of data elements were abstracted: 51 to 86 percent from structured data; the
remainder using natural language processing (NLP). In phase 1, data ingestion from 12
out of 20 feeds reached 95 percent accuracy. In phase 2, 55 percent of structured data
elements performed with 96 to 100 percent accuracy; NLP with 89 to 91 percent accuracy.
In phase 3, concordance ranged from 69 to 89 percent. Information retrieval statistics
were consistently above 90 percent.Conclusions: Semi-automated data abstraction may be
useful, although raw data collected as a byproduct of health care delivery is not
immediately available for use as real world evidence. New approaches to gathering and
analyzing extant data are required.

El legado de Alba Alonzo de Quesada en el reconocimiento y reivindicación de los Derechos Políticos de las Mujeres y en la Educación Superior de Honduras
Authors: Paz Guifarro Kenia Isabel , Jerez Moreno Rafael
Published: May 2018

Las reivindicaciones políticas, sociales y educativas de las mujeres en Honduras se han gestado y alcanzado producto del trabajo tesonero de distintos grupos feministas, organizaciones de sociedad civil y mujeres socialmente emprendedoras como Alba Alonzo de Quesada, Alejandrina Bermúdez de Villeda, María Antonia Martínez, Visitación Padilla y muchas otras mujeres y hombres comprometidos con la igualdad real y efectiva de ambos sexos.Estos movimientos sociales, alcanzaron, bajo sendos esfuerzos, el reconocimiento de los derechos civiles y políticos de las mujeres hondureñas en el año 1955, lo que ha permitido trabajar por consolidar una cultura de igualdad en el ámbito público, privado y doméstico, donde tradicionalmente ha dominado la cultura patriarcal. En ese sentido, el objeto de este ensayo es realizar una breve cronología sobre el desarrollo político y educativo a nivel superior de las mujeres en Honduras, donde la abogada Alonzo de Quesada fue protagonista, partiendo desde los antecedentes del acceso a la educación pública de las mujeres hondureñas hasta la integración de la Comisión de Transición Universitaria que ha marcado el rumbo de la Educación Superior nacional.

RESUMO Na busca de soluções viáveis para geração de energia através de fonte limpa e renovável, as tecnologias de conversão termoquímica de biomassa para obtenção de produtos com potencial energético são alvos de crescente interesse para a indústria e comunidade científica. Neste sentido a pirólise de lodo de ETE (Estação de tratamento de Esgoto), na presença e ausência do catalisador óxido de cálcio, ocorre através da  decomposição química de biomassa pelo calor e na ausência de oxigênio, que, além de promover uma valorização energética dos produtos derivados desta biomassa, aproveita um recurso que pode gerar um grave problema se descartado no meio ambiente, as frações obtidas neste processo: sólida, bio-óleo, aquosa (fração orgânica) e gasosa, que podem ser usadas para produção de calor e geração de energia. Os ensaios de pirólise ocorreram no tempo de residência de 120 minutos, temperatura de 450ºC e taxa de aquecimento de 30 minutos. A fração gasosa obtida através da pirólise do lodo de ETE possui alto poder calorífico e é composta por hidrocarbonetos de até 6 carbonos, hidrogênio (H2), monóxido de carbono (CO) e dióxido de carbono (CO2), a composição da fração gasosa foi determinada pela técnica de cromatografia a gás com detector de espectrometria de massa. O resultado apresentou uma grande quantidade de hidrocarbonetos com diferença significativa entre as amostras com ou sem catalisador, o que pode ser uma evidencia do rendimento deste processo para utilização do gás na matriz energética regional.

Published: May 2018

Introduction:

We evaluated the radiographic outcomes and surgical costs of surgically treated rotational ankle fractures in our health system between providers who had completed a trauma fellowship and those who had not.

Methods:

We grouped patients into those treated by trauma-trained orthopaedic surgeons (TTOS) and non–trauma-trained orthopaedic surgeons (NTTOS). We graded the quality of fracture reductions and calculated implant-related costs of treatment.

Results:

A total of 208 fractures met the inclusion criteria, with 119 in the TTOS group and 89 in the NTTOS group. Five patients lost reduction during the follow-up period. The adequacy of fracture reduction at final follow-up did not differ (P = 0.29). The median surgical cost was $2,940 for the NTTOS group and $1,233 for the TTOS group (P < 0.001).

Discussion:

We found no notable differences in radiographic outcomes between the TTOS and NTTOS groups. Cost analysis demonstrated markedly higher implant-related costs for the NTTOS group, with the median surgical cost being more than twice that for the TTOS group.

Influencia de la alta velocidad ferroviaria en la elección del destino turístico según el origen de los viajeros. El caso de la Costa Dorada en Cataluña
Authors: Saladié Òscar , Gutiérrez Aaron , Anton Clavé Salvador
Published: May 2018

La llegada de la alta velocidad ferroviaria (AVF) a Tarragona en 2006 añade otra opción de transporte para los turistas que se desplazan hasta un destino litoral como es la Costa Dorada (Cataluña). Mediante la aplicación de un método probabilístico causal hemos calculado el incremento en la probabilidad de que este destino turístico haya sido visitado debido a la existencia de la estación de AVF Camp de Tarragona. El trabajo se ha basado en los resultados de una encuesta a pasajeros españoles de la AVF que han realizado sus vacaciones en la Costa Dorada. Los resultados muestran que el incremento de probabilidad es mayor entre aquellos que residen en regiones más alejadas. Este incremento es de un 12% entre los pasajeros españoles de la AVF procedentes de Aragón y un 16,6% entre los de Madrid, regiones que representan casi dos terceras partes de los pasajeros de la muestra. Se ha demostrado también la existencia de importantes diferencias de carácter sociodemográfico y en relación con las características del viaje y de la estancia en función de la región de origen de los pasajeros.

Des de fa una dècada, s’ha multiplicat notablement el volum dels continguts en línia generats per usuaris i consumidors (UGC), juntament amb l’expansió dels mitjans de comunicació socials. En el camp de l’hoteleria i del turisme, s’ha produït un increment exponencial de les opinions en línia sobre viatges (OTR). En aquest article es proposa un mètode per analitzar les produccions paratextuals lligades a les OTR i extreure’n la imatge percebuda de la destinació segons la procedència dels turistes. El mètode s’aplica a una mostra aleatòria de 330.000 OTR allotjades a TripAdvisor, sobre Coses per Fer a Catalunya, escrites en castellà o en anglès entre 2011 i 2015. D’acord amb les opinions analitzades, pel que fa a la imatge percebuda (i transmesa) pels turistes de parla anglesa i, en especial, pels nord-americans, es pot concloure en síntesi que Catalunya és Barcelona i que Barcelona és Gaudí.

Cellular membrane affinity chromatography (CMAC) in drug discovery from complex natural matrices
Authors: Stephen Cayman , El Omri Abdelfatteh , Ciesla Lukasz M.
Published: May 2018

Secondary plant metabolites are evolutionary-designed molecules that interact with multiple biological targets in human organisms. Identification of pharmacologically active phytochemicals is usually a time consuming and costly process. Cellular membrane affinity chromatography (CMAC) allows the detection of secondary metabolites present in complex natural matrices, e.g. plant extracts and their interactions with the immobilized fully-functional transmembrane proteins. After the isolation process of the binding compounds, CMAC columns can be used to study the binding process between the potential new ligands and the immobilized transmembrane protein target. The following parameters can be determined using CMAC columns: binding affinity (Kd), association rate constant (kon), dissociation rate constant (koff) and the equilibrium constant for complex formation (K). This review summarizes the preparation steps and the use of CMAC columns in the drug discovery process of new potential drug leads present in complex natural matrices.

Introduction; p to 300 million people have the body mass index (BMI) greater than 30 kg/m2. Obesity is the cause of many serious diseases, such as type 2 diabetes, hypertension, and non-alcoholic fatty liver disease (NAFLD). Bariatric surgery is the only effective method of achieving weight loss in patients with morbid obesity. Objectives: The aim of the study was to assess the impact of bariatric surgery on non-alcoholic fatty liver disease in patients operated on due to morbid obesity. Material and Methods: We included 20 patients who were qualified for bariatric procedures based on BMI > 40 kg/ m2 or BMI > 35kg/m2 with the presence of comorbidities. The average body weight in the group was 143.85kg, with an average BMI of 49.16kg/m2. Before the procedure, we evaluated the severity of non-alcoholic fatty liver disease in each patient using the Sheriff-Saadeh ultrasound scale. We also evaluated the levels of liver enzymes. Follow-up evaluation was performed twelve months after surgery. Results: Twelve months after surgery, the average weight was 102.34 kg. The mean %WL was 33.01%, %EWL was 58.8%, and %EBMIL was 61.37%. All patients showed remission of fatty liver disease. Liver damage, evaluated with ultrasound imaging, decreased from an average of 1.85 on the Sheriff-Saadeh scale, before surgery, to 0.15 twelve months after surgery (p < 0.001). As regards liver enzymes, the level of alanine aminotransferase decreased from 64.5 (U/l) to 27.95 (U/l) (p < 0.001), and the level of aspartate aminotransferase decreased from 54.4 (U/l) to 27.2 (U/l). Conclusions: Bariatric procedures not only lead to a significant and lasting weight loss, but they also contribute to the reduction of fatty liver disease and improve liver function.

Left ventricular assist device (LVAD) is one of the modern management therapies in patients with advanced heart failure, and it serves as a bridge to heart transplantation or even as destination therapy. However, it is burdened with a high risk of thromboembolic, hemorrhagic, and infectious complications despite prophylactic management. Splenic abscesses, as septic complications following implantation of mechanical ventricular support, have not yet been described in the literature. We report of a patient with severe left ventricular insufficiency (NYHA II/III), pulmonary hypertension, and arrhythmia who underwent implantation of the Heart Ware® pump for left ventricular support with simultaneous tricuspidvalvoplasty, as a bridge therapy to heart transplantation. During two years after LVAD implantation, the patient had three MRSA skin infections, localized at the exit site of the drive-line connecting the artificial ventricle with external unit, that were complicated by sepsis and treated with broad-spectrum antibiotics. A few months later, abdominal CT revealed two abscesses in the spleen, and the patient was qualified for splenectomy. Open splenectomy was performed under full-dose anticoagulant therapy with continuous intravenous infusions of unfractionated heparin (UFH). The intra- and postoperative course was uneventful. UFH therapy was continued for 6 days, and oral anticoagulation was re-administered on day 4 after surgery. The patient was discharged on day 7 after surgery with primary healed wound. Open splenectomy, performed with full-dose anticoagulant therapy, proved to be an effective and definitive method of treatment without any complications.

Pilonidal cyst is a troublesome condition affecting usually young people. It significantly influences quality of life and causes low self-esteem. Despite its known pathophysiology and numerous therapeutic methods available, pilonidal cysts still constitute a significant problem in general surgery. A large number of surgical techniques indicates the lack of a single method that ensures therapeutic success, and frequent complications cause both patient’s dissatisfaction and frustration of the operator. In many cases, therapy is based on methods developed in a given healthcare center and their efficacy is usually not scientifically verified. Search for optimal strategy is also impeded by lack of an unambiguous clinical classification. In this article, we reviewed publications on various methods of managing pilonidal cyst, and we also presented surgical treatment used in our department. However, we did not manage to point out a surgical method with efficacy high enough to become standard treatment. It indicates the need for further search for new techniques that will give chances for successful treatment of pilonidal cyst.

The amputation of the lower limb is a crippling procedure, which impairs both physical and mental aspect of the patient’s life and therefore, it is important to provide these patients with comprehensive health care. Patients and their families must change their lives and reorganize them, which is undoubtedly associated with a decrease in the quality of life. The aim of this study was to analyze various determinants of quality of life in patients after lower limb amputation and their impact on the physical, mental and social aspect of life. Based on the available literature, this paper discusses certain factors determining quality of life, including the presence of phantom pain and stump pain, the way patients move, independence in daily activity, occupational activity, and access to rehabilitation. Analysis of the impact of particular factors on quality of life in people after lower limb amputation may contribute to the improvement and introduction of new paradigms regarding care provided for amputees.

Risk of recurrence after surgical treatment of a recurrent fistula is up to 50%. It has be known that more aggressive surgical treatment
is associated with a high risk of anal sphincter damage and leads to incontinence. Several studies have been designed to
elaborate minimally invasive treatment of rectovaginal and anal fistulas. The properties of Adipose-derived Stem Cells (ASC)
significantly enhance a natural healing potency. Here, we present our experience with combined surgical and cell therapy in the
treatment of fistulas.
Materials and Methods: Four patients were enrolled in our study after unsuccessful treatments in the past – patients 1-3 with rectovaginal
fistulas including two women after graciloplasty, and patient 4 - a male with complex perianal fistula. Adipose tissue
was obtained from subcutaneous tissue. ASCs were isolated, cultured up to 10+/-2 mln cells and injected into the walls of fistulas.
Follow-up physical examination and anoscopy were performed at 1, 4, 8, and 12 weeks, 6 and 12 months after implantation.
Results: Up to 8 weeks after ASC implantation, symptoms of fistulas’ tracts disappeared. At 8 weeks, in patients 1-3, communication
between vaginal and rectal openings was closed and at 12-16 w. intestinal continuity was restored in patient 3 and 4. After a
6-month follow-up, the fistula tract of patient 4 was closed. Up to 12 m. after ASC implantation no recurrences or adverse events
were observed.
Conclusion: ASCs combined with surgical pre-treated fistula tracts were used in four patients. All of them were healed. This encouraging
result needs further trials to evaluate the clinical efficiency and the cost-effectiveness ratio.
A novel model of acellular dermal matrix plug for anal fistula treatment. Report of a case and surgical consideration based on first utility in Poland

Published: May 2018

Anal fistula (AF) is a pathological connection between anus and skin in its surroundings. The main reason for the formation of anal fistula is a bacterial infection of the glands within the anal crypts. One of the modern techniques for the treatment of fistulas that do not interfere with the sphincters consists in implantation of a plug made from collagen material. We are presenting the first Polish experience with a new model of biomaterial plug for the treatment of anal fistula. We also point out key elements of the procedure (both preoperative and intraoperative) associated with this method. In the authors’ opinion, the method is simple, safe and reproducible. Innovative shape of the plug minimizes the risk of its migration and rotation. It also perfectly blends with and adapts to the course and shape of the fistula canal, allowing it to become incorporated and overgrown with tissue in the fistula canal. The relatively short operation time, minor postoperative pain and faster convalescence are with no doubt additional advantages of the method. Long-term observation involving more patients is essential for evaluation of the efficacy of the treatment of fistulas with the new type of plug.

The “Polish Research on Gastric Cancer” project has been continued since 1986. The main aim of this project, which is a multicenter and interdisciplinary research, is enhancing the treatment results of gastric cancer patients by developing and promoting the use of optimal methods for diagnosis and treatment, both surgical as well as combined. One of the more important achievements of the project is the development and publication of a document named “Polish Consensus on Treatment of Patients with Gastric Cancer”, whose first version was published in 1998. Following versions were updated adequately to changing trends in the proceedings in patients with gastric cancer. A scientific symposium on “Polish Consensus on Treatment of Gastric Cancer – update 2016” was held in 3-4 June 2016 in Cracow. During the symposium a panel session was held during which all authors publicly presented the Consensus assumptions to be discussed further. Moreover, the already mentioned session was preceded by a correspondence as well as a working meeting in order to consolidate the position. It has to be underlined that the directions and guidelines included in the Consensus are not the arbitrarily assumed rules of conduct in a legal aspect and as such every doctor/team of doctors is entitled to make different decisions as long as they are beneficial to a patient with gastric cancer. The Consensus discusses as follows: a) recommended qualifications (stage of advancement, pathological, lymph node topography and the extent of lymphadenectomy, division of cancer of the gastroesophageal junction), b) rules for diagnostics including recommendations regarding endoscopic examination and clinical evaluation of the advancement stage, c) recommendations regarding surgical treatment (extent of resection, extent of lymphadenectomy, tactics of proceedings in cancer of the gastroesophageal junction), d) recommendations regarding combined treatment with chemotherapy or radiotherapy, e) place of endoscopic and less invasive surgery in the treatment of gastric cancer. This publication is a summary of the arrangements made in the panel session during the abovementioned scientific symposium in Cracow in 2016.
