Published: March 2022

We conducted systematic reviews of predefined clinical questions and used the Grading of Recommendations, Assessment, Development and Evaluations approach to develop recommendations for the periendoscopic management of anticoagulant and antiplatelet drugs during acute gastrointestinal (GI) bleeding and the elective endoscopic setting. The following recommendations target patients presenting with acute GI bleeding: For patients on warfarin, we suggest against giving fresh frozen plasma or vitamin K; if needed, we suggest prothrombin complex concentrate (PCC) compared with fresh frozen plasma administration; for patients on direct oral anticoagulants (DOACs), we suggest against PCC administration; if on dabigatran, we suggest against the administration of idarucizumab, and if on rivaroxaban or apixaban, we suggest against andexanet alfa administration; for patients on antiplatelet agents, we suggest against platelet transfusions; and for patients on cardiac acetylsalicylic acid (ASA) for secondary prevention, we suggest against holding it, but if the ASA has been interrupted, we suggest resumption on the day hemostasis is endoscopically confirmed. The following recommendations target patients in the elective (planned) endoscopy setting: For patients on warfarin, we suggest continuation as opposed to temporary interruption (1–7 days), but if it is held for procedures with high risk of GI bleeding, we suggest against bridging anticoagulation unless the patient has a mechanical heart valve; for patients on DOACs, we suggest temporarily interrupting rather than continuing these; for patients on dual antiplatelet therapy for secondary prevention, we suggest temporary interruption of the P2Y12 receptor inhibitor while continuing ASA; and if on cardiac ASA monotherapy for secondary prevention, we suggest against its interruption. Evidence was insufficient in the following settings to permit recommendations. With acute GI bleeding in patients on warfarin, we could not recommend for or against PCC administration when compared with placebo. In the elective periprocedural endoscopy setting, we could not recommend for or against temporary interruption of the P2Y12 receptor inhibitor for patients on a single P2Y12 inhibiting agent. We were also unable to make a recommendation regarding same-day resumption of the drug vs 1–7 days after the procedure among patients prescribed anticoagulants (warfarin or DOACs) or P2Y12 receptor inhibitor drugs because of insufficient evidence.

Authors: Shah Eric D. , Amann Stephen T. , Hobley James , Islam Sameer , Taunk Raja , Wilson Louis
Published: March 2022

INTRODUCTION:

Prior authorizations (PAs) are intended to control prescription drug expenditures.

METHODS:

One hundred fifty-six physician and advanced practice provider members of the American College of Gastroenterology completed a national survey to assess PA burden and impact.

RESULTS:

One-half of PA requests relate to prescription refills. Greater than 50% of the respondents choose inferior treatments at least weekly because of perceived PA burden for preferred agents. One-half of the respondents reported a patient who experienced serious adverse events due to PA-related care delays.

DISCUSSION:

PA is an administrative burden that exhausts practice resources and may have a negative impact on patient care.

INTRODUCTION:

Syndecan-1 (SDC1) has multiple functions in tumorigenesis in general and specifically in pancreatic cancer. We aimed to evaluate SDC1 as a diagnostic and prognostic biomarker in patients with pancreatic ductal adenocarcinoma (PDAC).

METHODS:

In this case-control study, patients newly diagnosed with a biopsy-proven PDAC were enrolled alongside healthy individuals in a derivation-validation cohort design. Serum SDC1 was measured by enzyme-linked immunoassay. The diagnostic accuracy of SDC1 levels for diagnosing PDAC was computed. A unified cohort enriched with additional early-stage patients with PDAC was used to evaluate the association of SDC1 with survival outcomes and patient characteristics.

RESULTS:

In the derivation cohort, serum SDC1 levels were significantly higher in patients with PDAC (n = 39) compared with healthy controls (n = 20) (40.1 ng/mL, interquartile range 29.8–95.3 vs 25.6 ng/mL, interquartile range 17.1–29.8, respectively; P < 0.001). The receiver operating characteristic analysis area under the curve was 0.847 (95% confidence interval 0.747–0.947, P < 0.001). These results were replicated in a separate age-matched validation cohort (n = 38 PDAC, n = 38 controls; area under the curve 0.844, 95% confidence interval 0.757–0.932, P < 0.001). In the combined-enriched PDAC cohort (n = 110), using a cutoff of 35 ng/mL, the median overall 5-year survival between patients below and above this cutoff was not significantly different, although a trend for better survival after 1 year was found in the lower level group (P = 0.06). There were 12 of the 110 patients with PDAC (11%) who had normal CA 19-9 in the presence of elevated SDC1.

DISCUSSION:

These findings suggest serum SDC1 as a promising novel biomarker for early blood-based diagnosis of pancreatic cancer.

Published: March 2022

Archaeological evidence indicates that Birnirk peoples (AD 650 – 1300) are the proposed genetic ancestors of the Thule Inuit (AD 950 – 1400) and are potentially an intermediary population between the Thule Inuit and earlier Old Bering Sea people (AD 1 – 1000). We sequenced the first hypervariable region of the mitochondrial DNA of 22 clearly associated Birnirk individuals from the Piġniq (Birnirk), Kugok, Kugusugaruk, and Nunavak sites on the North Slope of Alaska. Haplotypes A2a, A2a1, A2a3, A2b1, and D4b1a2a1a were identified in this population, demonstrating an expansion of Birnirk maternal genetic diversity. Maternal lineages from these individuals were evaluated with other past and contemporary Inuit populations from the Chukotka Peninsula to eastern Greenland. Our findings confirm Birnirk Inuit as probable maternal ancestors to Thule Inuit and may be among the first peoples possessing these lineages to have moved into the western North American Arctic from the Bering Strait region.

Experimental study to enhance the productivity of single-slope single-basin solar still
Authors: Diabil Hayder Azeez Neamah
Published: March 2022

Existence of potable water is considered as one of the important issues that are related to the survival of human life, especially in fresh water scarce areas. So, it is necessary to find a solution to this problem. In the current work, the productivity of fresh water in conventional single-slope single-basin solar still is increased by using two modification methods. The first method is reflecting the solar ray to the still basin by using aluminum foils that are pasted on the interior surfaces of the still walls. This method will enhance the fallen solar rays on basin water and reduce heat losses. The second method increases the evaporation surface area by introducing blackened stainless steel balls with different diameters at the still basin. Balls of two diameters chosen: 5 and 10 mm. The experimental results show that the productivity of solar still with 10 mm-diameter balls is higher than that of the conventional solar still by 38.07%. The corresponding values of the stills with 5 mm-diameter balls and aluminum foils are 31.41 and 14.87%, respectively. The thermal efficiency of the highest productivity solar still is 27.81%. Other stills are characterized by lower thermal efficiencies by various rates.
Surface roughness prediction of wire electric discharge machining (WEDM)-machined AZ91D magnesium alloy using multilayer perceptron, ensemble neural network, and evolving product-unit neural network
Authors: Gurgenc Turan , Altay Osman
Published: March 2022

Magnesium (Mg) alloy parts have become very interesting in industries due to their lightness and high specific strengths. The production of Mg alloys by conventional manufacturing methods is difficult due to their high affinity for oxygen, low melting points, and flammable properties. These problems can be solved using nontraditional methods such as wire electric discharge machining (WEDM). The parts with a quality surface have better properties such as fatigue, wear, and corrosion resistance. Determining the surface roughness (SR) by analytical and experimental methods is very difficult, time-consuming, and costly. These disadvantages can be eliminated by predicting the SR with artificial intelligence methods. In this study, AZ91D was cut with WEDM in different voltage (V), pulse-on-time (µs), pulse-off-time (µs), and wire speed (mm s−1) parameters. The SR was measured using a profilometer, and a total of 81 data were obtained. Multilayer perceptron, ensemble neural network and optimization-based evolving product-unit neural network (EPUNN) were used to predict the SR. It was observed that the EPUNN method performed better than the other two methods. The use of this model in industries producing Mg alloys with WEDM expected to provide advantages such as time, material, and cost.
Effect of FeTi-FeB inoculation on the shape of carbide reinforcements in hypoeutectic high chromium white cast iron
Authors: Teker Tanju , Yilmaz S. Osman , Dalmiş İ. Savaş
Published: March 2022

FeTi-FeB was added to molten high chromium white cast iron in amounts of 0.5–2.5 wt% at 50 °C above the melting temperature. The samples were produced in four groups. The first group samples were investigated as cast, the second group homogenized at 1000 °C for 1 h, and the other two groups were also homogenized at 1000 °C but for 3 and 6 h, respectively. To study the effect of FeB and FeTi on the microstructure, the samples were characterized by optical microscopy, scanning electron microscopy, energy dispersive spectroscopy, X-ray diffraction and hardness tests. Wear tests were performed using a pin-on disc. A homogeneously dispersed carbide microstructure was produced by the homogenization heat treatment method. The addition of FeTi-FeB inoculants to high Cr white cast iron played an important role in the distribution of hard carbides. The chemical rate and the carbide volume varied on account of the added hard inoculant particles. TiB2, Cr3C2, M7C3, M23C6, and γ-FeCr phases formed on the surfaces. The hardness and wear resistance were improved considerably due to FeTi-B inoculation.
The sacred pool of Ba'al: a reinterpretation of the ‘Kothon’ at Motya
Authors: Nigro Lorenzo
Published: March 2022

The Phoenician island-city of Motya, off the west coast of Sicily, has long been a focus of archaeological research. Earlier excavations identified a large rectangular basin interpreted, by analogy with Carthage, as a ‘kothon’ or artificial inner harbour. Recent investigations of this feature, however, lead the author to a new interpretation. Rather than a harbour, the so-called ‘Kothon’ is revealed as a sacred freshwater pool at the centre of a monumental circular sanctuary hosting three large temples. The pool, watched over by a statue of Ba'al, also served as a surface for observing and mapping the movement of stars, as emphasised by the alignment of structures and features positioned around the sacred enclosure.

Digital marketing adalah salah satu cara pemasaran yang saat ini sedang diminati oleh para pelaku usaha, melalui digital marketing ini pelaku usaha bisa memasarkan produk hasil buatannya. Pelaku UMKM di Desa Muntung memproduksi snack atau makanan yang berbahan baku dari tepung terigu. Produk kembang jambu ini merupakan salah satu produk unggulan dan diminati oleh warga masyarakat di sekutar Desa Muntung. Pemasaran kembang jambu masih menggunakan pemasaran manual, seperti dititipkan di warung-warung terdekat, atau bahkan para pembeli datang langsung ke lokasi produksi kembang jambu tersebut. Hal inilah yang menjadikan Kelompok KKN Unnes yang berjumlah 13 orang untuk membantu para pelaku UMKM dalam teknik pemasarannya.  Ada 2  UMKM yang sudah berjalan lancar di Desa Muntung ini, namun masih disayangkan jika teknik pemasaran dan pengemasan masih tradisional. teknik pemasaran melalui digital marketing adalah salah satu upaya untuk meningkatkan produksi karena melalui digital marketing khalayak umum akan lebih tau produk-produk yang dijual terlebih jika memang produknya merupakan produk yang berkualitas. Sementara itu, dari hasil wawancara awal dengan pelaku usaha mikro produk makanan, baik produsen maupun retailer mengakui bahwa kemasan produk mempengaruhi citra produk. Namun pemahaman mereka tentang kemasan produk masih sangat minim. Menurut mereka kemasan hanya sekedar wadah dan pembungkus makanan agar tidak rusak. Permasalahan lain yaitu mereka tidak mempunyai kemampuan dana untuk mengemas produknya dengan baik. Dengan situasi persaingan semakin tajam, desain sebuah kemasan merupakan suatu nilai tambah, dapat berfungsi sebagai media promosi dan untuk menjaring konsumen.

Published: March 2022

El trabajo presenta una reflexión que intenta problematizar las disputas que se están desarrollando en el continente nuestroamericano a partir de la irrupción de varios gobiernos de derecha (Brasil, Ecuador, Uruguay) y otros que endurecieron su accionar frente a demanda de diversos grupos populares (Chile, Colombia). Dichos gobiernos se vieron robustecidos luego de la elección de Donald Trump en Estados Unidos (ésta fue marcada por la crisis del sistema capitalista del 2008). Esta doble situación llevó a estallidos sociales populares que buscan hacer retroceder las posiciones de derecha y al mismo tiempo están buscando convertirse en proyectos políticos que coloquen al ser humano en el centro, dejando de lado a la mercancía, las ganancias y al mercado por no considerarlas entidades sagradas

Environmental impacts of rare earth production
Authors: Zapp Petra , Schreiber Andrea , Marx Josefine , Kuckshinrichs Wilhelm
Published: March 2022

Rare earth elements (REEs) are important raw materials for green technologies. However, REE mining and production uses techniques that are often not environmentally sustainable. Life cycle assessment (LCA) is a well-recognized method for evaluating the environmental impacts of products and technologies. This article provides an overview of the environmental impacts based on published LCA results of primary REE production. Existing major REE deposits (Bayan Obo in China, Mountain Pass in the United States, Mount Weld in Australia, ion-adsorption deposits in several Chinese southern provinces) and currently possible production routes are compared. Alternative minerals, such as eudialyte, are also discussed. The article shows which environmental effects can be minimized by technology optimization and environmental safety strategies. Additionally, some of the environmental impacts discussed, may be difficult to mitigate, as they depend on the mineral type. Activities along the complex process chain of REEs production that have particularly high environmental impacts are identified.

Ujemne stopy procentowe a inwestycje w nieruchomości w świetle teorii Silvia Gesella
Authors: Mirowski Piotr
Published: March 2022

Objective: The article discusses a somewhat forgotten theory of the German economist Silvio Gesell concerning money free from interest, and even charged for its possession, i.e. the Gesell tax. The article presents the escape from money and whether investment in real estate is justified, as well as the limitations of such investment.Research Design & Methods: The author analyses the subject literature. The theoretical issues presented in S. Gesell’s source works were interpreted in the light of contemporary economic processes and theoretical studies on his work.Findings: One of the modern expressions of Gesell’s theory is negative nominal interest rates, which have become a contemporary policy tool. While until recently even the theoretical application of such a tool was rarely considered, it has now become an important consideration in the economic reality of many economies. The natural defence of those with savings is to flee money that is burdened with fees. Real estate investment is an alternative vehicle to cash, though it is not without its limitations.Implications / Recommendations: Negative nominal interest rates have become a monetary policy tool, and there are indeed conditions that justify their use. However, it is natural for those with free cash to run away from “taxed” negative cash flows into investments that will maintain the value of their capital. One such investment is investing in real estate, though it is not without its limitations.Contribution: The author discusses the Gesell tax, a rarely analysed theory that has a contemporary, practical expression. He links it with real estate, a subject that is widely discussed today.

Antropofagia en el arte de Adriana Varejão
Authors:   Universidad de Lodz, Kubiak Ewa
Published: March 2022

Adriana Varejão (born in 1964) is one of the most well-known contemporary Brazilian artists. Her artistic output include works made in various techniques; both paintings, installations and drawings. In her work, she holds a dialogue with the past, she is particularly interested in colonial history and racial diversity, which to this day constitute important aspects shaping modern Brazilian society. The article concerns one of the important motifs that have permanently become present in the artist’s work: anthropophagy. The analysis has covered both iconographic elements and formal aspects of the artist’s works, in which she refers to this motif. What cannot be ignored is a dialogue, which in this case is held with the modernist concept of anthropophagy defining the identity of the Brazilian culture, shaped in the avant-garde trend of artistic reflection in Brazil in the 1920s.
Memorias fotográficas: tres visiones de la Argentina posdictatorial
Authors:   Universidad de Buenos Aires, Fortuny Natalia
Published: March 2022

Recent photographic essays investigate and make visible the relationship with the traumatic past of the last and most ferocious Argentine dictatorship (1976- 1983). These post-dictatorial images work as photographic memories: artistic visual artifacts based on the resource of photography and in dialogue with a recent past. These images matter here not so much for their adaptation to a recorded event but for their particular construction, strategies and production processes of meaning. In this framework, it will be analyzed the works of three photographic artists. First, the photographs with which Helen Zout evokes the machines and death devices launched in the Clandestine Detention Centers by the last military dictatorship. Secondly, the reconstructed photos by Lucila Quieto, a photographer whose father, Carlos Quieto, was disappeared by the last Argentine military dictatorship, when Lucila was not yet born. Her photographic serie Archeology of the absence arose from the lack of photos with her father in the family album and the need to visually reconstruct an impossible moment. Finally, the work Calle 30 Nº1134 by photographer Hugo Aveta will open the question as to whether the remains of the past can be created – that is, invented.
Plastic-viscosity-based mix design and effect of limestone on self-compacting concrete
Authors: Mimoun Abdulkarim , Kulasegaram Sivakumar
Published: March 2022

The advantages of using self-compacting concrete (SCC) in comparison to traditional vibrated concrete are widely acknowledged. One of the key challenges in producing a consistent SCC mix lies in the ability to control its performance both in fresh and hardened states. Several methodologies are currently used for mix proportion design of SCC to achieve better quality and strength. In this work the consistency of a plastic-viscosity (PV)-based mix-proportioning method was investigated by exploring the fresh-state flow properties and hardened-state compressive strengths of SCC mixes produced using Portland limestone cement (PLC). SCC design mixes with target compressive strengths between 30 and 70 MPa were tested. It was found that while using the chosen PLC type, the mix-proportioning method based on estimation of PV failed to achieve the predicted compressive strength in the case of target mix strength of 60 MPa and above. The aim of this paper is to propose a procedure to mitigate this discrepancy by demonstrating that the quality and performance of the SCC produced using PV-based mix design can be influenced by the cement type used and this can also affect the target compressive strength achieved by the concrete mix.
Calculation of capacity of crusher with stops on a roll
Authors: Nikitin A. G. , Shabunov M. E. , Gerike P. B.
Published: March 2022

All industrial metallurgical enterprises produce and use milled materials obtained by crushing. In the global energy balance, the share of produced energy consumed for crushing is more than 5 %. This paper considers a scheme of the crusher with stops on a roll, the structure of which forms a complex stress state in a crushed piece under one­time action of normal and tangential stresses. It is shown that when generating a complex stress state in a fragmented piece of brittle material, the energy consumption is less by 30 – 40 % than when acting in a piece of linear normal stress. The authors developed a method for determining capacity of the drive electric motor of an energy-saving crusher with stop on a roll at design stage.

La “sociología de la desviación” omite las significacionescorporales y de género del uso de drogas. Finalmente, se describe el paradigma posmoderno o de “normalización”. Conclusiones. Es necesario articular la agencia individual a los condicionantes sociales; dar cuenta de la experiencia corporal y de género de las prácticas de consumo, en tanto dimensiones políticas de los (no) usos de drogas.

Authors: Vinasco Barco Jaime Andrés
Published: March 2022

Objetivo. Hacer una clasificación de los sujetos que adquieren el cannabis en los dispensarios legales de la ciudad de San Diego (California, Estados Unidos) para luego importarlo, difundirlo y/o comerciarlo en la ciudad de Tijuana (Baja California, México). Metodología. La estrategia de recolección de datos fue la observación participante y la entrevista semi-estructurada. Se trabajó con 21 sujetos de Tijuana que accedieron a los Medical Marijuana Dispensaries (MMDs) de San Diego durante los años 2014 a 2018. Resultados. Los importadores de cannabis se clasifican en a) Cannabis Importers by camaraderie, b) Cannabis Importers by self-supply, y c) Cannabis Importers by business. Conclusiones. Los sujetos que importan el cannabis de San Diego hacia Tijuana conforman un sistema alternativo de comercio, organización social y resolución de conflictos frente al acceso al cannabis. Este sistema es diferente al narcotráfico, la auto-provisión (autocultivo) y los sistemas que proveen los Estados.

Cannabis plantations as an aspect of population survival and as a public policy and security issue in the northeast region of Brazil
Authors: Fraga Paulo , Martins Rogéria
Published: March 2022

Based on historical and structural data, this article aims to discuss the cultivation of cannabis as a social and political issue in Brazil. The objective was to analyze the genesis of the issue of illegal plantations, its evolution, the governmental response and its consequences for public security and agricultural policies in the São Francisco Valley region, in the Northeast of Brazil. Qualitative methodologies were used with emphasis on the descriptive analysis of the phenomenon. The result is that the state steps that affected the environment, the Brazilian drug policy, the inefficient agricultural policy for the semi-arid region and the plantation eradication measures are directly and indirectly related to the continuation of the plantations as relevant economic and criminal activities.
The Tetrahydroevolution of Cannabis. A reference to production, refining and current presentation of Cannabis
Authors: Vinasco-Barco Jaime Andrés
Published: March 2022

Objective: To refer the main processes of production, refinement and current presentation of cannabis. Methodology: An observation of the processes of production, refining and presentation of cannabis in crops, laboratories and clinics in California (United States) and Baja California (Mexico) was made. Findings: Three dimensions are proposed to refer to the current cannabis production, refining and presentation processes: 1) The neo-cannabis production: A cannabis production characterized by fast and higher yields, 2) The neo-refining of cannabis: An extreme use of cannabis characterized by different methods that extract its main components, and 3) The neo-presentation of cannabis: A contemporary presentation of cannabis in new and plural commercial forms. Conclusions: Cannabis has had a development in recent decades that is far superior to the development of the plant throughout its existence. The name tetrahydroevolution of cannabis is suggested for this process.
Violencia sexual y reproductiva hacia mujeres que se inyectan drogas en la frontera norte de México. ¿La frontera de los derechos?
Authors: Ospina-Escobar Angélica
Published: March 2022

Objetivo: evidenciar las experiencias de violencia que enfrentan mujeres usuarias de drogas inyectables residentes en Ciudad Juárez, México. Metodología: se analizan 14 entrevistas en profundidad recolectadas por la autora durante el 2013 en espacios de trabajo sexual y en instalaciones de organizaciones de la sociedad civil. Resultados: los datos muestran que la superposición de las condiciones de género, pobreza y uso de drogas sobreexpone a las mujeres entrevistadas a vivir experiencias de violencia de todo tipo, desde la violencia sexual hasta la separación de sus hijos e hijas. Conclusiones: es necesario la formulación de políticas de drogas con perspectiva de género que atienda las necesidades particulares de las mujeres, en especial aquellas dirigidas a la elaboración del trauma y la deconstrucción de expectativas de género. Sensibilizar a personal de salud en reducción de daños y derechos humanos de personas con uso problemático de drogas es fundamental para mejorar la calidad de los servicios que se ofrecen a mujeres con uso problemático de drogas.

Cannabis medicinal y recreativo: una hermenéutica crítica de las nociones de salud y enfermedad relativas al consumo de marihuana
Authors: Lynch Fernando
Published: March 2022

Se plantea una lectura hermenéutica crítica de las nociones de salud y enfermedad implicadas en la prohibición de las drogas psicoactivas, de entre las cuales la marihuana constituye un caso paradigmático. Se observa que, según su raigambre religiosa, la noción de salud subyacente a la prohibición reside en el ideal de completa sobriedad inherente a la lógica abstencionista. Se destaca que el concordante presupuesto naturalista del diagnóstico de enfermedad, en tanto confiere todo el poder a la substancia, conlleva consecuencias de-subjetivantes. Ejemplificando el caso con la legalización del consumo medicinal de cannabis, se concluye considerando la siguiente paradoja: mientras en estos casos se acepta que la marihuana es un medicamento, por cuanto se ha producido su aprobación social generalizada, por el contrario, en tanto su consumo recreativo no conlleva una utilidad manifiesta, terapéutica en particular, sigue siendo considerado una práctica viciosa, una conducta enfermiza que sigue ameritando su condena social.

Authors: Basílico Daiana , Sapienza Cinthia , Rosa Marina , Jeifetz Vanesa
Published: March 2022

Objetivo: estudiar el estado de aplicación de la ley argentina 26.657, respecto a personas con uso problemático de drogas. Metodología: estudio cualitativo, exploratorio-descriptivo llevado a cabo entre octubre 2018 y octubre 2019. Entrevistas semidirigidas a profesionales de la salud de hospitales generales y de efectores de primer nivel de atención, del Área Metropolitana de Buenos Aires. Resultados: habitualmente no se considera a las personas con consumos problemáticos como pacientes de salud mental, presentando dificultades para la accesibilidad a los tratamientos. Conclusión: existen prácticas aisladas en concordancia con la ley, pero falta una mayor incorporación y sistematización de estas. Hay una ausencia de políticas públicas que acompañen la implementación de esta ley, entre ellas falta de recursos materiales y humanos. Es necesario un cambio de paradigma en quienes gestionan las instituciones, asisten a las personas con uso problemático de drogas y en los propios usuarios del sistema de salud.
