Authors: Aljabab Mhanna A. , Algharbi Muteb , Huggare Jan , Bazargani Farhan 
Published: May 2021

ABSTRACT

Objectives
To explore whether there were any differences in orthodontic treatment need, treatment complexity, treatment time, or the number of visits between a group of children receiving early intervention (extraction of upper and lower deciduous canines) and an age- and condition-matched control group without intervention.

Materials and Methods
Patient records and study casts in the late mixed or early permanent dentitions of 46 subjects (20 from the extraction group and 26 from the control group) of an earlier prospective longitudinal study were retrieved. Orthodontic treatment need and complexity were assessed by the index of complexity, outcome, and need (ICON). Statistical calculations were performed by t-test for parametric outcome variables (treatment time, number of visits, and orthodontic treatment need) and Fisher exact test for the categorical variable (tooth extractions).

Results
There were no statistically significant differences between the groups in ICON scores of orthodontic treatment need (extraction group, mean score 59.8; control group, mean score 52.8), number of visits (mean of about 15 visits for both groups), or treatment time (extraction group, mean 21.5 months; control group, mean 20.3 months). The extraction of permanent teeth was more prevalent in the deciduous canine extraction group (59%) as compared with the control group (28%); however, this was not statistically significant (P = .07) but showed a tendency toward worsening the crowding and the future need of orthodontic extractions.

Conclusions
Early removal of deciduous primary canines will reduce neither the need for later orthodontic treatment nor its complexity, nor will it shorten the treatment time.

OBJECTIVEType 2 diabetes is an established risk factor for dementia. However, the roles of glycemic control and diabetic complications in the development of dementia have been less well substantiated. This large-scale cohort study aims to examine associations of longitudinal HbA1c levels and diabetic complications with the risk of dementia incidence among patients with type 2 diabetes.RESEARCH DESIGN AND METHODSData of eligible patients with diabetes, aged ≥50 years in the U.K. Clinical Practice Research Datalink from 1987 to 2018, were analyzed. Time-varying Cox regressions were used to estimate adjusted hazard ratios (HRs) and 95% CIs for dementia risk.RESULTSAmong 457,902 patients with diabetes, 28,627 (6.3%) incident dementia cases were observed during a median of 6 years’ follow-up. Patients with recorded hypoglycemic events or microvascular complications were at higher risk of dementia incidence compared with those without such complications (HR 1.30 [95% CI 1.22–1.39] and 1.10 [1.06–1.14], respectively). The HbA1c level, modeled as a time-varying exposure, was associated with increased dementia risk (HR 1.08 [95% CI 1.07–1.09] per 1% HbA1c increment) among 372,287 patients with diabetes with postdiagnosis HbA1c records. Similarly, a higher coefficient of variation of HbA1c during the initial 3 years of follow-up was associated with higher subsequent dementia risk (HR 1.03 [95% CI 1.01–1.04] per 1-SD increment).CONCLUSIONSHigher or unstable HbA1c levels and the presence of diabetic complications in patients with type 2 diabetes are associated with increased dementia risk. Effective management of glycemia might have a significant role in maintaining cognitive health among older adults with diabetes.

Abstract

OBJECTIVE
To evaluate whether mesenchymal stem cells (MSCs) can be safely administered IV to dogs with congestive heart failure (CHF) secondary to myxomatous mitral valve disease (MMVD) to improve cardiac function and prolong survival time.

ANIMALS
10 client-owned dogs with CHF secondary to MMVD.

PROCEDURES
Dogs with an initial episode of CHF secondary to MMVD were enrolled in a double-blind, placebo-controlled clinical trial. Five dogs in the MSC group received allogeneic Wharton jelly–derived MSCs (2 X 106 cells/kg, IV), and 5 dogs in the placebo group received a 1% solution of autologous serum (IV) for 3 injections 3 weeks apart. Cell-release criteria included trilineage differentiation, expression of CD44 and CD90 and not CD34 and major histocompatability complex class II, normal karyotype, and absence of contamination by pathogenic microorganisms. Patients were followed for 6 months or until death or euthanasia. Echocardiographic data, ECG findings, serum cardiac biomarker concentrations, CBC, and serum biochemical analysis results were obtained prior to and 4 hours after the first injection and every 3 months after the final injection.

RESULTS
Lymphocyte and eosinophil counts decreased significantly 4 hours after injection, and monocytes decreased significantly only in dogs that received an MSC injection. No significant differences were seen in the echocardiographic variables, ECG results, serum cardiac biomarker concentrations, survival time, and time to first diuretic drug dosage escalation between the 2 groups.

CONCLUSIONS AND CLINICAL RELEVANCE
This study showed that MSCs can be easily collected from canine Wharton jelly as an allogeneic source of MSCs and can be safely delivered IV to dogs with CHF secondary to MMVD.
Impact of specimen type on findings for bacterial composition within the intestinal tract of dogs and cats with and without chronic enteropathy
Authors: Summers Stacie C. , Galloni Allysa , Webb Craig B. 
Published: May 2021

Abstract

OBJECTIVE
To compare bacterial diversity and community composition among fecal, rectal swab, and colonic mucosal biopsy specimens from dogs and cats with and without chronic enteropathy (CE).

ANIMALS
9 healthy dogs, 8 dogs with CE, 8 healthy cats, and 9 cats with CE.

PROCEDURES
In a cross-sectional study design, fecal, rectal swab, and colonic mucosal biopsy specimens were obtained by colonoscopy from healthy dogs and dogs and cats with CE. Fecal and rectal swab specimens were collected from healthy cats. Genomic DNA was extracted, the 16S rRNA V4 gene region was amplified, and sequencing was performed by use of primers 515F to 806R on a paired-end platform.

RESULTS
For healthy dogs and dogs and cats with CE, bacterial diversity based on the Chao1 estimate of total species richness was higher for colonic mucosal biopsy specimens than for fecal specimens. Analysis of similarities by use of the Bray-Curtis dissimilarity index revealed that the bacterial communities captured in rectal swab specimens were similar to those captured in fecal specimens for healthy dogs and dogs with CE and similar to those captured in colonic mucosal biopsy specimens for both dog groups and cats with CE.

CONCLUSIONS AND CLINICAL RELEVANCE
Rectal swab and colonic biopsy specimens were successfully used to characterize the bacteriome of the intestinal tract in dogs and cats by 16S rRNA gene sequencing. Although the specimen types evaluated in this study were not interchangeable in results, rectal swab specimens were practical to collect from dogs and cats to study bacterial composition within the intestinal tract and may provide an alternative to colonic mucosal biopsy and fecal specimens.
A Review of Imaging and Sensing Technologies for Field Phenotyping

Published: May 2021

Abstract
Over the past few decades, food production has been sufficient. However, climate change has already affected crop yields around the world. With climate change and population growth, threats to future food production come. Among the solutions to this crisis, breeding is deemed one of the most effective ways. However, traditional phenotyping in breeding is time-consuming as it requires thousands and thousands of individuals. Mechanisms and structures of stress tolerance have a great variability. Today, bigger emphasis is placed on the selection of crops based on genotype information and this still requires phenotypic data. Their use is limited by insufficient phenotypic data, including the information on stress photosynthetic responses. The latest research seeks to bring rapid, non-destructive imaging and sensing technology to agriculture, in order to greatly accelerate the in-field measurements of phenotypes and increase the phenotypic data. This paper presents a review of the imaging and sensing technologies for the field phenotyping to describe its development in the last few years.

Published: May 2021

Abstract
The process of integration into the European Union (EU) requires from new member states significant efforts; not only harmonizing legislation but also respecting all posed standards. Among numerous issues, wastewater purification represents a significant request. To achieve the goal of discharging good-quality water into natural water bodies as recipients, various methods have been used. The method of constructed wetland (CW) is based on wastewater purification by using wetland plants. The method of CWs shows the best results for small settlements for up to 5,000 inhabitants and can be nicely integrated within the landscape of a plain where waterbodies’ banks are overgrown by wetland plants. Such facilities have been used for decades in the territory of the EU, and only a few have been built in the Republic of Serbia. Since the Republic of Serbia is a candidate country for the EU, there is a strong intention to take action focused upon solving wastewater purification from various sources. Therefore, this paper aims to examine favourable locations for CW installations within the rural area of the South Bačka District. Geographic information system was applied for examination of the basic spatial criteria (distance from the settlement, distance from water bodies, elevation, and land use). These were presented in separate maps and finally in one joint map of favourability for establishing CWs in the vicinity of 35 villages within the District. The obtained results have fulfilled the basic spatial preconditions, but further analyses should be conducted to precisely position the location of each CW concerning land ownership criterion.
Estimación de la carga máxima de sedimentos para la determinación de la formación de bancos de arena sobre el Río Cauca, Jamundí-Valle del Cauca
Authors: Paz Zúñiga Eduard 
Published: May 2021

La estimación de la carga máxima de sedimentos sobre el lecho de río permite determinar las zonas de acumulación y posterior formación de bancos de arena, en este artículo se presentan los resultados de la estimación de la carga máxima de sedimentos sobre el lecho del Río Cauca. La zona de estudio se caracteriza por presentar un gradiente bajo y de forma sinusoidal, además de una climatología tropical de solo dos estaciones, donde se tienen temporadas de lluvia en la que se da el transporte, seguidas de calurosas épocas de verano donde se acumula el material de arrastre sobre el lecho del río, características suficientes para la formación de bancos de arena. Se partió de estudios realizados en ríos con características fluviales y topográficas muy parecidas a las de la zona de estudio, los cuales, a partir de la aplicación de modelos matemáticos a los valores de pixel de las fotografías aéreas del río, permitieron el reconocimiento de cauce y formación de bancos de arena sobre el lecho. Para el cálculo de transporte de sedimentos o carga de fondo se utilizó la relación de Meyer- Peter & Muller (Ferguson, 2008) y la función de Shields, Church (2006), modelos que dependen de las características topográficas del lecho del río. Se utilizó el modelo digital de elevación obtenido del procesamiento fotogramétrico, así mismo, se estableció un tamaño de grano de 4mm y una velocidad virtual de 1.3 m/s, para el reconocimiento definitivo del lecho se optó por las funciones de potencia y tensión de corte o erosión Lorang et al. (2005). Los resultados obtenidos mostraron que el Río Cauca tiene gran capacidad de acumulación, al igual que de transporte de sedimentos, se destacaron zonas de acumulación, que para el año de estudio presentaban un potencial para la formación de bancos de arena, los que a la fecha continúan siendo explotados, los resultados de carga de fondo, formación de bancos de arena y reconocimiento del lecho de río, mostraron coherencia entre sí, permitiendo tener validez en los resultados, para un río de las características estudiado.
Flowshop scheduling with machine deterioration based on job sequences
Authors: Ruiz-Torres Alex , Rosas Jose Ablanedo , Jurburg Daniel 
Published: May 2021

This paper addresses the two-machine permutation flowshop problem with deterioration. The objectives are minimizing the makespan and the average tardiness. Jobs have a baseline process time in each machine and have a due date. The actual time to process a job depends on the machine performance level at the start of each job, which is a function of the previously processed jobs and their wear/deterioration effect on the machine. The article proposes multiple heuristics and a comprehensive set of experiments. The results indicate that as a group, the heuristics generate solutions that are very close to the optimal for both criteria. Furthermore, no heuristic approach is dominant for all experimental conditions, thus heuristic selection to solve practical problems should be based on the specific problem characteristics.
Ilse Fusková. Cuerpo, estética y memoria cuir
Authors: Bidaseca Karina , Nuñez Lodwick Lucia 
Published: May 2021

Este trabajo se propone indagar en el artivismo de Ilse Fusková, referente histórico del feminis-mo lesbiano de Buenos Aires, a partir de la teoría del archivo. El cuerpo vivo de la artista y su obra son el archivo de nuestra historia feminista y disidente. Apelamos a la construcción de una memoria cuir y colectiva frente a la deshistorización de las grandes narrativas que tendieron al borramiento de las disidencias sexuales, cuyas vivencias en la región fueron atravesadas por la violencia política y las represiones estatales. Ergo este texto es una apuesta a la reivindicación de la experiencia estético-poético-política de los cuerpos insumisos.

La sistematización en Trabajo Social y la epistemología feminista del punto de vista. Diálogos sobre la producción de conocimiento sustentada en experiencias
Authors: Parola Ruth Noemí , Linardelli Maria Florencia 
Published: May 2021

El presente artículo discute sobre la sistematización desde una óptica singular: la perspectiva de la epistemología feminista del punto de vista, por su proximidad con algunas inquietudes que nos planteamos en Trabajo Social. Se trata de un análisis en el que los procedimientos propios del trabajo teórico de las ciencias sociales son acompañados por nuestras experiencias de investigación, docencia y sistematización en el campo del Trabajo Social. El argumento central de artículo sostiene que, desde una posición epistemológica feminista, el desapego y la distancia más que una prueba de objetividad y validez resultan de un prejuicio cientificista. La subjetividad no es vista como un obstáculo, sino como elemento constitutivo de la producción de conocimiento. Así, uno de los rasgos distintivos de la sistematización de experiencias -quien reflexiona e interpreta es el/la protagonista que experimenta- deja de ser un obstáculo para su validez y relevancia, para convertirse en una posibilidad de aportar un punto de vista singular: la perspectiva de quienes con su práctica cotidiana se insertan en un escenario que, a la vez, pretenden conocer y abordar reflexivamente. En las conclusiones destacamos que algunas características de la sistematización de experiencias que han sido consideradas problemáticas para la producción de conocimiento, pueden comprenderse como potencialidades si dejamos de lado las perspectivas androcéntricas.

Published: May 2021

El presente artículo contiene los resultados de la Sistematización de la Experiencia del Proyecto de Asesoría Familiar: “Reconocimiento de los derechos humanos del Adulto Mayor en dos familias residentes en Cali y Valledupar”. Se desarrolló durante los meses de febrero a noviembre del año 2017, a través de un proceso participativo con las familias S. P. en Valledupar y C. V. en Cali, para alcanzar el reconocimiento familiar y social de los adultos mayores como sujeto de derechos, fomentando su participación y realzando sus recursos y competencias, desde una perspectiva de derechos humanos y del apoyo intergeneracional.
Ahora bien, la construcción del proyecto se realizó por medio de la integración de aportes de la Investigación Acción Participativa y la Metodología del Marco Lógico; la implementación fue ejecutada en escenarios de asesoría familiar desde un Enfoque Sistémico en el que emergieron dos ejes fundamentales: la participación social y la corresponsabilidad. Finalmente, en los resultados fue predominante el importante papel que ejerce la familia para que los adultos mayores sean reconocidos como sujetos de derecho.
