Authors: Tummalapalli Sri Lekha , Powe Neil R. , Keyhani Salomeh 
Published: July 2019

Background and objectives
Improving the quality of CKD care has important public health implications to delay disease progression and prevent ESKD. National trends of the quality of CKD care are not well established. Furthermore, it is unknown whether gaps in quality of care are due to lack of physician awareness of CKD status of patients or other factors.

Design, setting, participants, & measurements
We performed a national, serial, cross-sectional study of visits to office-based ambulatory care practices for adults with diagnosed CKD from the years 2006 to 2014. We assessed the following quality indicators: (1) BP measurement, (2) uncontrolled hypertension, (3) uncontrolled diabetes, (4) angiotensin-converting enzyme inhibitor or angiotensin receptor blocker use among patients with hypertension, (5) statin use if age ≥50 years old, and (6) nonsteroidal anti-inflammatory drug use. Using multivariable linear regression and chi-squared analysis, we examined the change in quality performance over time.

Results
Between 2006 and 2014, there were 7099 unweighted visits for patients with CKD representing 186,961,565 weighted visits. There was no difference in the prevalence of uncontrolled hypertension (>130/80 mm Hg) over time (46% in 2006–2008 versus 48% in 2012–2014; P=0.50). There was a high prevalence of uncontrolled diabetes in 2012–2014 (40% for hemoglobin A1c >7%). The prevalence of ACEi/ARB use decreased from 45% in 2006–2008 to 36% in 2012–2014, which did not reach statistical significance (P=0.07). Statin use in patients with CKD who were 50 years or older was low and remained unchanged from 29% in 2006–2008 to 31% in 2012–2014 (P=0.92).

Conclusions
In a nationally representative dataset, we found that patients with CKD had a high prevalence of uncontrolled hypertension and diabetes and a low use of statins that did not improve over time and was not concordant with guidelines.
Avoidance of Double Taxation in the Area of Income Tax in Latvia
Authors: Lazdiņš Jānis , Ketners Kārlis 
Published: July 2019

The article is dedicated to the experience of preventing double taxation in the Republic of Latvia, the area of income tax. This topic is made relevant by the tax reform implemented in 2018. Although the payment of income tax has been conceptually changed, the authors propose the thesis regarding a constant approach to prevention of double taxation, based on recommendations by the Organisation for Economic Co-operation and Development (hereinafter – OECD). In the framework of income tax reform, additional requirements have been integrated into regulatory enactments to eliminate the possibility of tax evasion.
Collateral in Public Register as a Security of Private Debt
Authors: Rozenfelds Jānis 
Published: July 2019

This article deals with approaches to establishment of the collateral. Registration in public registers is a precondition to establish a mortgage and a commercial pledge, where the first one is recorded in the Land Register, while the second – in the Register of Commercial Pledges. Unlike the mortgages, execution of rights to a commercial pledge depends not only on registration, but also on whether a pledgee has taken actual possession of property. Taking of possession has not been expressly set forth by Latvian laws. It is necessary to specify the moment in legal acts when the pledged property was actually taken into possession. The subject of a mortgage is immovable property. The subject of a commercial pledge is movable property. Immovable property cannot be the subject of a commercial pledge. Distinction between movable and immovable property may lead to a situation when a holder of the commercial pledge loses the collateral due to the fact that the subject of pledge, once moveable, has turned into immovable property. The collateral is also endangered by the fact that public reliability is not necessarily always attributed to all public registers in all situations. Legal regulation of the register of commercial pledges more corresponds with the principle of public reliability. This principle, however, is not clearly defined for land registers and is variously interpreted by courts, thus leaving negative influence upon the stability of pledge rights. It is highlighted in Latvian law that existence of the collateral depends on whether there is a claim secured by a pledge (accessoriness). Current practise differs from that in the interwar period in Latvia. The difference lies within such secured claims that cannot be executed by force due to the limitation period or other reasons. Such changes in practise have led to the situation when secured claims may not be executed in case of insolvency of a debtor if the creditor has been in default to apply his claim within the term set by the insolvency administrator.

Published: July 2019

Objetivo: el trasplante hepático es el tratamiento de elección para la falla hepática aguda y crónica. Los resultados en el trasplante hepático han mejorado en los últimos años, así que el objetivo de nuestro trabajo es comparar la experiencia de un centro en Colombia en dos períodos de tiempo diferentes.
Pacientes y métodos: estudio descriptivo retrospectivo donde se analizaron pacientes adultos con primer trasplante hepático en dos períodos; serie 1, entre 2004-2010 (241 pacientes); y serie 2, entre 2011-2016 (142 pacientes).
Resultados: la edad promedio fue de 54 años, el 57 % eran hombres y con un puntaje Model for End-stage Liver Disease (MELD) promedio de 20, sin cambios significativos en las características del donante y del receptor en los dos períodos. Las principales indicaciones de trasplante hepático fueron cirrosis por alcohol, cirrosis criptogénica y cirrosis por hepatitis autoinmune, con una disminución de los casos de hepatitis B y C en la serie 2. El 30 % de los pacientes tenía hepatocarcinoma. La supervivencia de los pacientes a 1 año fue de 81 % frente a 91 % y a 5 años fue de 71 % frente a 80 %, respectivamente. Las principales causas de muerte fueron: cáncer, enfermedad cardiovascular y sepsis. Existió un incremento significativo en las complicaciones biliares, sin diferencias en las complicaciones infecciosas, vasculares y el rechazo celular entre los dos períodos.
Conclusión: el trasplante hepático en este centro en Colombia se relaciona con excelentes resultados a corto y mediano plazo, con una mejoría significativa en la supervivencia de los pacientes en los últimos años y con resultados similares a los reportados en otros centros del mundo.

Authors: Castaño Llano Rodrigo , Puerta Díaz Juan Darío , Palacios Fuenmayor Luis José , Uribe Moreno Diego 
Published: July 2019

Antecedentes: la cirugía transanal endoscópica es un abordaje mínimamente invasivo recientemente descrito, que provee una exposición superior y permite el acceso a las lesiones del recto en toda su extensión. Además, provee un riesgo menor de compromiso de los márgenes de resección, menores tasas de recurrencia y una menor morbimortalidad en comparación con la escisión transanal convencional o las remociones endoscópicas. Objetivos: se pretende describir la experiencia inicial y los resultados con la cirugía transanal mínimamente invasiva (transanal minimally invasive surgery, TAMIS) en términos de resecciones completas y posibles complicaciones relacionadas con el procedimiento. Materiales y métodos: esta una serie de casos con un seguimiento prospectivo de los pacientes con TAMIS. Se analizaron los resultados de 27 pacientes intervenidos en varios centros de Medellín, Colombia, entre enero de 2012 y diciembre de 2016, realizados con cirugía laparoscópica monopuerto (single-port laparoscopic surgery, SILS) (21 casos) o el GelPOINT® Path (6 casos), junto con el apoyo de la óptica del laparoscopio (16 pacientes) y del endoscopio flexible (11 pacientes). Resultados: se realizaron 27 TAMIS en el mismo número de pacientes, 10 mujeres (37 %) y 17 hombres fueron evaluados. Se realizó un seguimiento a los pacientes durante aproximadamente 12 meses, en promedio 32 meses. La edad promedio fue de 68 años (52-83 años). El tamaño promedio del tumor fue de 5,3 cm (2-9 cm) y la distancia promedio desde el margen anal fue de 7 cm (5-9 cm) Las complicaciones posoperatorias se dieron en 6 casos (22 %) Una perforación rectal se corrigió por vía laparoscópica en el mismo acto quirúrgico y otra por la misma vía transanal. Una estenosis rectal se manejó con dilatación digital, y hubo un caso de sangrado rectal menor, uno de retención urinaria y un paciente presentó un cáncer rectal avanzado a los tres meses de la resección con margen microscópico positivo (4 %). No hubo reingresos. La mortalidad por la intervención fue nula. La patología operatoria reportó la presencia de adenoma de bajo grado en 3 casos (11 %), de alto grado en 11 (41 %), adenocarcinoma in situ en 6 (22 %), tumor neuroendocrino en 5 pacientes (18 %), 1 caso de fibrosis cicatricial (4 %) y 1 de leiomioma (4 %). Limitaciones: los resultados no son extrapolables a la población general debido al poco número de intervenciones y la ejecución limitada a solo dos autores. Conclusiones: en nuestra experiencia inicial, TAMIS es un procedimiento mínimamente invasivo con una baja morbilidad posoperatoria, es curativa para lesiones benignas y para pacientes seleccionados con cáncer temprano.

OBJECTIVE
Posttransplantation diabetes mellitus (PTDM) contributes to risk for cardiovascular morbidity and mortality in renal transplant recipients (RTRs). In the general population, consumption of a diet containing few fruits and vegetables predisposes to type 2 diabetes. The role of diet as a potential modifiable risk factor for PTDM has not been explored. Our focus was to investigate the prospective associations of fruit and vegetable intake with risk of PTDM in stable RTRs.

RESEARCH DESIGN AND METHODS
We included 472 adult RTRs who had a functioning graft ≥1 year. Fruit and vegetable intake was assessed by using a 177-item food frequency questionnaire. PTDM was defined according the American Diabetes Association’s diagnostic criteria for diabetes.

RESULTS
During 5.2 years of follow-up, 52 RTRs (11%) developed PTDM. Fruit intake was not associated with PTDM (hazard ratio [HR] 0.90 [95% CI 0.79–1.03] per 2log g/day; P = 0.13), whereas vegetable intake was inversely associated with PTDM (HR 0.77 [95% CI 0.63–0.94] per 2log g/day; P = 0.009). Mediation analyses revealed that ±50% of the association between vegetable intake and PTDM was mediated by variations in key components of the metabolic syndrome (i.e., HDL cholesterol, triglycerides, and waist circumference) as determined by the National Cholesterol Education Program’s Adult Treatment Panel III Expert Panel.

CONCLUSIONS
In this study vegetable intake, but not fruit intake, was associated with lower risk of PTDM in RTRs, likely largely through beneficial effects on key components of the metabolic syndrome. These findings further support accumulating evidence that supports a recommendation of higher vegetable intake by RTRs.

Authors: Moghaddam Reihaneh Kardehi , Yazdan Navid Moshtaghi 
Published: July 2019

Abstract
The present research studied fault diagnosis of composite sheets using vibration signal processing and artificial intelligence (AI)-based methods. To this end, vibration signals were collected from sound and faulty composite plates. Using different time-frequency signal analysis and processing methods, a number of features were extracted from these signals and the most effective features containing further information on these composite plates were provided as input to different classification systems. The output of these classification systems reveals the faults in composite plates. The different types of classification systems used in this research were the support vector machine (SVM), adaptive neuro-fuzzy inference system (ANFIS), k-nearest neighbor (k-NN), artificial neural networks (ANNs), Extended Classifier System (XCS) algorithm, and the proposed improved XCS algorithm. The research results were reflective of the superiority of ANFIS in terms of precision, while this method had the highest process duration with an equal number of iterations. The precision of the proposed improved XCS method was lower than that of ANFIS, but the duration of the process was shorter than the ANFIS method with an equal number of iterations.

Published: July 2019

Abstract
The present study reports the linear elastic analysis of variable thickness functionally graded rotating disks. Disk material is graded radially by varying the volume fraction ratios of the constituent components. Three types of distribution laws, namely power law, exponential law and Mori–Tanaka scheme are considered on a concave thickness profile rotating disk, and the resulting deformation and stresses are evaluated for clamped-free boundary condition. The investigation is carried out using element based grading of material properties on the discretized elements. The effect of grading on deformation and stresses is investigated for each type of material distribution law. Further, a comparison is made between different types of distributions. The results obtained show that in a rotating disk, the deformation and stress fields can be controlled by the distribution law and grading parameter n of the volume fraction ratio.

Authors: Jagadeesh V. , Venkatasubbaiah K. , Lakshumu Naidu A. 
Published: July 2019

Abstract
Nowadays, natural fiber reinforced polymer composites are widely used because of their advantageous properties like minimum density, maximum specific strength, low cost and easy availability. Manufacturing of natural fiber composite is easy as compared to the conventional methods. In the present scenario, due to an increasing interest in environmental consciousness with greenhouse effect, various industries have initiated the use of eco-friendly materials and are replacing hazardous materials with such eco-friendly materials. The present work aims to determine the tensile strength of okra and jute fibers reinforced in Epoxy LY-556 and XIN-100IN Resins. Okra fibers are developed from the stem of the plant of the Malvaceae family. Their use as reinforcement in polymer composites requires the basic knowledge of their mechanical properties. Jute fibers are developed from the best jute plants. The conclusions are based on their mechanical properties and behavior.
Finite element model updating using Lagrange interpolation
Authors: Asma F. 
Published: July 2019

Abstract
In this paper, an iterative finite element model updating method in structural dynamics is proposed. This uses information matrices and element connectivity matrices to reconstruct the corrected model by reproducing the frequency response at measured degrees of freedom. Indicators have been proposed to quantify the mismodelling errors based on a development in Lagrange matrix interpolation. When applied on simulated truss structures, the model gives satisfactory results by detecting and quantifying the defaults of the initial model.

Load-carrying capacity of the GFRP and CFRP composite beams subjected to three-point bending test – numerical investigations
Authors: Banat Dominik 
Published: July 2019

Abstract
The subject of this article is the finite element method (FEM) simulation of the multi-layered rectangular composite beam subjected to three-point bending test. The study is focused on the composite beams made of glass or carbon fibre-reinforced laminates (glass fibre-reinforced polymer [GFRP] and carbon fibre-reinforced polymer [CFRP]) for which different laminate stacking were addressed. Three beam geometries with various length-to-thickness ratios included short beam shear (SBS) test, provided the beam is short relative to its thickness, which maximised the induced shear stresses. Simulation included the application of Tsai–Hill, Hoffman, Tsai–Wu, Hashin and Puck failure criteria to perform the composite beam failure analysis wherein the matrix and fibre failure were considered separately. Numerical failure studies also aimed to verify the beam failure modes and the participation of stress tensor elements in material failure.
