Objetivo: determinar la tasa de detección de los adenomas (TDA) e identificar las indicaciones de colonoscopia que predicen su hallazgo.
Materiales y métodos: estudio de corte transversal. Se incluyeron pacientes mayores de 18 años sometidos a colonoscopia entre febrero y julio de 2020 en un centro especializado de Medellín, Colombia. Se estimó la TDA y se identificaron las indicaciones de colonoscopia, que se consideran predictores para el hallazgo de adenomas.
Resultados: la detección general de adenomas fue del 21 % (n = 992) y la TDA en la población de tamizaje fue del 25 %. El rango de 40 a 49 años aportó el 12 % del total de adenomas detectados y la población masculina tuvo mayor incidencia (OR 1,73; IC 95 % 1,25-2,38; p < 0,001). El antecedente personal de pólipos (OR 1,86; IC 95 % 1,25-2,78; p = 0,002) y la presencia de sangre oculta en heces (OR 2,67; IC 95 % 1,12-6,35; p 0,026) se consideran predictores para el hallazgo de adenomas. El uso de filtros LCI mostró mejores resultados en la detección de las lesiones (OR 1,43; IC 95 % 1,02-2,0).
Conclusiones: las indicaciones de la colonoscopia pueden predecir la probabilidad de detección de adenomas. El género masculino, el antecedente personal de pólipos, la presencia de sangre oculta en heces y la búsqueda de adenomas a partir de los 40 años son las variables que aumentan la probabilidad de encontrar adenomas. El uso de filtros LCI aumenta la detección de lesiones. La edad sugerida para el inicio del tamizaje de CCR es a partir de los 40 años.

Authors: Gaudenyi Tivadar , Mihajlović Milan 
Published: March 2022

The Carpathian Basin introduced in the geographical literature of the year 1921. However, after few clarifications it became in official use in 1947. It has been used in the context of landscape unit or physico-geographical entity mainly by the Central European geoscientists.
The Carpathian Basin bordered by the Alps, the Carpathians, the Dinaric Mountains and Šumadija Mountains. It represents the lowlands (and mountains which they encircled) as well as the slopes of mountains which faced to the lowlands.
After numerous multidisciplinary analysis (surface geology and roughness, orography, slope angles) the area of the Carpathian Basin delineated and presented. The analysis shown that the Carpathian Basin excludes the intramontane basins in the Carpathians and the Dinaric Mountains.

Alcoolismo em pacientes submetidos à cirurgia bariátrica: notas sobre a transferência da compulsão
Authors: Souza Antônio Augusto Mascarenhas de , Weber César Augusto Trinta 
Published: March 2022

Introdução: Ao longo da vivência clínica psiquiátrica nos deparamos muito com pacientes que após o tratamento cirúrgico para a obesidade desenvolvem transtornos relacionados ao álcool. Isso nos leva a questionar a existência ou não de um mecanismo de transferência da compulsão, o que antes era um transtorno alimentar passa a ser um transtorno aditivo. Objetivo: Investigar a associação do alcoolismo em pacientes submetidos à cirurgia bariátrica. Método: Revisão de literatura das produções científicas na modalidade textual de artigos, indexados na base de dados MEDLINE, por meio da ferramenta de busca livre PUBMED, realizada em junho de 2021, pelo uso das palavras-chave selecionadas segundo o Medical Subject Headings: alcoholism, bariatric surgery, substance use, drug use, addiction. Foram elegíveis 7 publicações para este estudo. Resultados: Os estudos revisados apresentaram resultados convergentes na associação entre pacientes submetidos à cirurgia bariátrica e alcoolismo. Ainda que as técnicas possam ser distintas, os transtornos relacionados ao álcool parecem estar mais relacionados à técnica de Bypass gástrico em Y de Roux. Conclusões: O alcoolismo em pacientes submetidos à cirurgia bariátrica está associado às complicações médicas pós-operatórias. Devemos levar em consideração a importância da necessidade de identificar os pacientes em risco de tais problemas, idealmente antes da cirurgia. Os dados revisados sugerem que tanto a cirurgia de Bypass gástrico em Y de Roux quanto o Sleeve gástrico, afetam dramaticamente a farmacocinética do álcool e causam uma provável transferência da compulsão (alimento X álcool) envolvendo o sistema de recompensa da via dopaminérgica mesolímbica. Devemos recomendar que os pacientes de alto risco ou pacientes com cirurgia de Bypass gástrico em Y de Roux) se abstenham do uso de álcool após a cirurgia bariátrica devido ao metabolismo alterado do álcool, bem como o potencial para transtornos por uso de álcool após a cirurgia.

Abstract
The Belayim Marine field, in the Gulf of Suez Egypt, presents many challenges to drilling operators. The most challenging section of the well is the 900-m, 16-in openhole containing a 13 5/8-in casing interval. The main risks in this section are the highly reactive salt layers in combination with high potential saltwater flow zones.
This interval is frequently drilled with a heavy 2.0-sg OBM to avoid saltwater influx during the drilling operations. Due to the mobility of the salt and unstable shale formations, the casing is run without centralizers to minimize the risks of not getting the casing to the desired section depth. Initially the interval was cemented using a 2.16-sg cement system with extended thickening time, both having the same 2.16-sg density. An external casing packer is used as an additional barrier in the event the cement placement does not achieve zonal isolation across the casing due to poor standoff.
After saltwater flow was observed at surface following the installation of the BOP, a detailed review of the casing and cementing design was performed to obtain a more robust procedure to avoid similar events in the future. Cement placement, operation design, and slurry properties were reviewed and optimized. The optimization was performed using details obtained from proprietary simulators as well as by optimizing the slurry properties in the laboratory. The cement operation design called for a single slurry scheme with very critical parameters, ensuring the cement will remain in the liquid phase to maintain applied pressure on the flow zone formations until the BOP is secured. The slurry design itself was revised and optimized in the laboratory providing right angle set along with good transition time to avoid any saltwater influx from formation fluids.
The optimized cement design and slurry properties have met all challenges. Furthermore, the new cement design in conjunction with the external casing packer succeeded in stopping the water flow influx and no similar events have occurred since the new cement operations design began being used in the field.

В современной практике инженерных расчетов все более востребованным и повсеместным становится применение численных методик. В статье дается подробный обзор наиболее перспективной и все более востребованной модели грунтов модели упрочняющегося грунта (Hardening soil model (HSM)). Также приводится краткий обзор грунтовых моделей, которые до сих пор широко используются в отечественной практике инженерных расчетов с применением численных методов, модели, которые являлись предшествующими по отношению к модели HSM, на которых собственно, она основана. Изучение математических моделей грунтов в численных расчетах является залогом корректного применения компьютерных программ, залогом от бездумного нажимания клавиш компьютера, а значит залогом повышения надежности и безопасности строительства зданий и сооружений, а также повышения экономической эффективности проектов строительства.
These days structural as well as geotechnical tasks usually being solved with the help of numerical analytical technics. The practice of using analytical methods based on linearelastic behavior assumptions become less and less popular or even outdated. Huge growth of computer numerical power gives opportunity for development and application of advanced and complicated nonlinear mathematical soil models. Understanding basics of soil mechanics and the constitutive mathematical models describing soils behavior are crucial for correct usage of fi niteelements software and computer analysis of geotechnical everyday tasks. One of the most popular soil model used these days in engineering practice is the hardening soil model (HSM) proposed by T. Shanz in 1999. The article gives a thorough review of the development of HS model which is based on linear MohrCoulomb model and hyperbolic DuncanChang model.
