Construcción de vivienda, correción monetaria y desarrollo nacional: Comentarios sobre el impacto del UPAC
Authors: Ternent James Anthony 
Published: January 2023

• Resumen: La construcción de vivienda no es un sector líder porque tiene elasticidades-precio e ingresos y nexos limitados con otros sectores; ésto es particularmente válido para vivienda de bajo costo. El empleo en el sector, herramienta importante de la política anticíclica es -sin embargo- inestable y de baja remuneración. La expansión en la construcción parece responder moderadamente a aumentos reales en el crédito y parece que no ha limitado el flujo de fondos hacia otros sectores; la vivienda, en Colombia, ha tenido una alta prioridad en los últimos lustros y el instrumento del crédito ha permitido traducir en demanda efectiva a una gran parte de la demanda latente. Ahora bien, en el país las corporaciones de ahorro y vivienda han descartado el financiamiento de vivienda popular, la que sería provista por la filtración de unidades existentes. En fin, cambiar sustancialmente o aun eliminar el sistema de indexación existente no sería fácil dados los intereses en juego. • Abstract: House construction is not a leading sector as shown by its low income and price elasticities and its limited ties with other sectors. This is particulary true for low cost housing. The sectors employment, an important tool when applying anti-cyclical policies, is, nevertheless, unstable and badly paid. An expansion on construction apparently responds moderately to real credit growth and seems not to have Iimited the flow of resources to other sectors. Housing, in Colombia, has had a high priority in the Iast years and credit, used as a policy instrument, has allowed the transformation of a latent demand into current demand. Now then, in the country the housing and savings corporations have discarded the financing of popular housing, which should be provided by leaks in existing units. That is, substantially changing even eliminating the existing indexation system would not be easy considering the different interests involved.
La teoría marxista del valor: Balance crítico de los debates recientes
Authors: De Vroey Michael 
Published: January 2023

• Resumen: La teoría económica marxista ha sufrido una grave crisis en los últimos años, lo que se manifiesta en el desacuerdo entre las varias líneas de interpretación. La teoría del valor es la base de la construcción analítica de Marx y este artículo presenta un panorama de las distintas versiones actuales -énfasis en la noción de trabajo abstracto o en la forma dineraria del valor-, en relación con la economía política del equilibrio. Al final se plantea que la ambigüedad teórica de Marx sólo podrá ser superada reconociendo el fracaso de mucha parte de su análisis y aceptando algunas pistas que el pensamiento heterodoxo moderno plantea: la idea de "separación" y su simétrica obligada, la economía monetaria. • Abstract: Marxist economic theory has gone through a severe crisis in the last few years. This crisis reveals itself in the disagreement between the different interpretations. The value theory, as Marx's analytical construction basis, is used in this article to present a panoramic view of the different current versions with an emphasis on the idea of abstract labor, where value takes a monetary form, in relationship to political economy and general equilibrium, or the neoricardian theory. The last part of the article, states that Marx theoretical ambiguity can only be overcome once the failure of some parts of its analysis recognized and it accepts certain clues stated in modern heterodox economic though, such as the idea of "separation" and its obliged symmetry monetary economics.
El "efecto calendario" y la especificación de un modelo de series de tiempo para la demanda de electricidad
Authors: Castaño Elkin 
Published: January 2023

Muchas de las series de tiempo tratadas en la práctica son observadas mensualmente y debido a que el número de veces que cada día de la semana ocurre varía con el mes, la serie puede estar afectada por la variación en los días comerciales. Algunas de estas series también pueden estar influenciadas por otros efectos de calendario tales como la Semana Santa y días de fiesta. El presente documento presenta una aplicación del método de Bell y Hillmer, basado en funciones de transferencia, para modelar los efectos por variaciones en los días comerciales y el efecto de la Semana Santa y el empleo del análisis de observaciones atípicas para detectar efectos calendario en la serie de demanda de energía eléctrica de las Empresas Públicas de Medellín. Se comparan los resultados con los del modelo que no considera dichos efectos.
Ley de Say" y "ley de Keynes": crisis y leyes en crisis
Authors: Posada Carlos Esteban 
Published: January 2023

El siguiente artículo es una divagación en el campo de la relevancia y de las limitaciones de dos grandes "leyes" de la Macroeconomía; así como también del enfoque teórico que dominó la transición entre tales leyes. A pesar de que el tema de este artículo es bastante amplio, su tratamiento en estas páginas es muy simplificado. Se concluye que, un esquema ecléctico en materia doctrinal, que integre en forma lógica los aportes de las teorías clásica y keynesiana al tema del crecimiento y de las crisis, tiene mayor poder explicativo de la evolución económica de los principales países capitalistas en los años 70 que cualquier esquema clásico o keynesiano que intentase una interpretación doctrinalmente 'pura" de este asunto. De aquí surge, probablemente, la conveniencia de un conocimiento crítico de las "leyes" de Say de Keynes.

Authors: Bogotá Galarza Blanca Lyda , Cardona Quintero Fernán Alonso 
Published: January 2023

El presente artículo se propone establecer las implicaciones tributarias de la implementación del proyecto BEPS 2.0 de la Organización para la Cooperación y Desarrollo, OCDE, firmado por Colombia el 01 de julio de 2021. Para tal efecto, se aborda de manera general el estado actual de la implementación del plan BEPS de la OCDE para luego emprender los aspectos generales del proyecto BEPS 2.0 y las posibles implicaciones tributarias de su implementación en Colombia.

Dicho proyecto aborda los retos de la digitalización de la economía y cuenta con dos (2) pilares, a saber:

Pilar 1: se basa en asegurar una distribución más justa de las utilidades y derechos impositivos entre los países con relación a los grupos multinacionales, no solo con las compañías que prestan servicios digitales automatizados sino también empresas orientadas al consumidor.

Pilar 2: contempla imponer una tarifa efectiva de al menos 15% en los países en que operen las multinacionales, para con ello lograr que los países puedan proteger sus bases gravables.

En este contexto, se analizó los trabajos realizados por la Organización para la Cooperación y Desarrollo Económico, OCDE, de la cual Colombia es parte desde el 30 de mayo de 2018, y los cambios regulatorios en el sistema tributario colombiano.

Published: January 2023

El Síndrome de Burnout se considera una respuesta patológica al estrés en el trabajo que trae consecuencias en la salud y bienestar de los trabajadores modernos. La presente investigación tiene como objetivo conocer las implicaciones que el Síndrome de Burnout tiene en los contadores públicos independientes de las Pymes de la ciudad de Cúcuta durante la pandemia del Covid-19. Los métodos y técnicas usadas fueron de carácter exploratorio, descriptivo, con trabajo de campo, con la aplicación de una encuesta de selección múltiple con escala de Likert que incluyó el Malash Burnout Inventory, MBI, a una muestra de 85 contadores públicos independientes. Los resultados indican que hay un nivel alto de Burnout para el agotamiento y despersonalización y una baja realización personal, indicando un alto estrés al que se ven expuestos los contadores públicos. Como conclusión, se deben buscar estrategias para prevenir y mitigar los efectos del Burnout.
El derecho al retracto y sus inconsistencias dentro del ordenamiento jurídico colombiano
Authors: Sanabria Vélez Maria Alejandra 
Published: January 2023

In Colombia, Law 1480/2011, that establishes the consumer statute, includes several benefits for consumers which do not include exhaustive criteria that limit the exercise of their rights; therefore, this statute may violate the principle of Pacta Sunt Servanda. This law contains some prerogatives that exceed the consumption relationship, since it incorporates legal loopholes that violate the rights of producers and suppliers in Colombia. For example, absence of parameters and solid limits to allow differentiation between a consumption relationship and a business relationship. Notwithstanding the foregoing, the aim of this article is to discuss the withdrawal right and its consequences.
This article studies whether the right of withdrawal contained in article 47 of Law 1480 of 2011 is aligned with other provisions of the Colombian legal system, and if this power blurs the autonomy of the will of the parties. Finally, it proposes some criteria that may be used by the legislator, to regulate more adequately the right of withdrawal.
Validation of Spinal Cord Injury Sensory Deficit Model with Head-Fixed Rat

Published: January 2023

Background/Objective: Numerous studies have reported restoring motor function through spinal cord stimulation in a rodent spinal cord injury model; however, replicating sensory information through spinal cord stimulation has not been thoroughly tested.We have previously trained rats to detect artificial sensations which lead to the question if this can be generated in a spinal cord injured rat. Our study begins to address this question by first validating a spinal cord injury model to test. Our hypothesis is if a decrease in the percent correct response compared to pre-procedure is observed, then this will verify sensory loss in this dorsal column lesion model of spinal cord injury.
Methods: We use sensory detection in a head-fixed rat to verify a spinal cord injury sensory deficit model. We begin by placing a water-deprived rat into a custom-made head-fix set up where two water spouts are placed in front of the rat. Vibration stimuli is applied to the hind paw via a vibration motor set at 200 hz ± 50 hz. The rat is trained to associate stimulus with left spout and no stimulus with right spout. Correct percent response is recorded and once rat demonstrates detection, the rat undergoes a dorsal column hemi-section procedure. Post procedure, the rat will be placed back in the head-fix set up to repeat the behavioral experiment.
Results: Thus far, only habituation training has been completed with the rat. The following steps include detection training, dorsal column hemi section, and re doing the detection training to measure a difference in correct response rate.
Conclusion and Potential Impact:This is a crucial step for spinal cord injury research as this confirms sensory loss and will allow further testing to restore sensation. After validation, we can begin testing to restore sensation using stimulation of the spinal cord.
HLA-E and HLA-G Co-expression in Porcine Endothelial Cells Attenuates Human Natural Killer Cells degranulation
Authors: Farag Kristine , Cross-Najafi Arthur , Wilmes Danielle , Kundu Debjyoti , Zhang Wenjun , Ekser Burcin , Li Ping 
Published: January 2023

Background: Xenotransplantation offers a prospective solution to organ shortage. The elimination of major xenoantigens in pig cells prevents hyperacute xenograft rejection (HXR), driven by preformed antibodies. However, acute xenograft rejection (AXR), driven by immune cell activation,continues to be a barrier in pig-to-human xenotransplantation. Natural killer (NK) cells, with inhibitory and activating receptors, play unique roles in AXR by promoting graft rejection or tolerance. NK cell tolerance occurs naturally in utero where human leukocyte antigen (HLA)-E and HLA-G are present. Expressing HLA-E/G in xenografts may provide immune protection from human NK cell cytotoxicity.
Methods: This study aims to demonstrate the use of HLA class I molecules in inducing human NK cell tolerance. 5-gene-knock-out (5GKO) porcine endothelial cells (pECs) were transfected with HLA-E and HLA-G genes. Transfected cells were stained with HLA-E and/or HLA-G antibody. HLA class I expressing 5GKO cells were isolated by flow sorter. Genetically modified pECs were co-cultured with human peripheral blood mononuclear cells (PBMCs) for E:T ratio of 10:1 for 2 hours. PBMCs were collected and stained with fluorochrome-conjugated antibodies. NK cell degranulation was accessed by the percentage of CD107a expression in the CD3-CD56+population. Co-localization of HLA-E and HLA-G on pECs was imaged by immunofluorescence microscopy and quantified by Image-Pro.
Results: 5GKO pEC lines expressing HLA-E, HLA-G, and co-expressing HLA-E and HLA-G were successfully established. Co-expression of HLA-E and HLA-G in 5GKO pECs reduced human NK cell degranulation by 50% compared to the 21% reduction achieved with 5GKO alone (p<0.0001). Co-localization intersection of 5GKO.HLA-E.HLA-G with stimulated PBMCs was not significantly different than when cultured with media (0.067 vs. 0.059, p=0.57).
Conclusion and Impacts: Co-expression of HLA-E and HLA-G in 5GKO pECs significantly reduced human NK cell degranulation, compared to 5GKO.HLA-E, 5GKO.HLA-G, and 5GKO pECs. However, co-localization of HLA-E and HLA-G didn’t change when cultured with stimulated PBMCs. This study provides insight into the interactions between HLA molecules that promote an immunotolerant phenotype.
Analysis of Girls Inc.’s Redefining Beauty Curriculum in the Prevention of Eating Disorders
Authors: Farris Kelsey , Messmore Niki , Stone Jade 
Published: January 2023

Background: Eating disorders are commonly diagnosed psychiatric disorders in adolescents. Because of the severity of disease and difficulty of treatment, means of prevention are important. Girls Inc. is a national non-profit organization that delivers evidence-based programming for people identifying as girls. Their four-week summer camp includes curriculum for building relationships, economic and media literacy, body image, and self-esteem. Here, the Girls Inc. curriculum “Redefining Beauty” is evaluated for efficacy of changing attitudes and behaviors correlated with development of eating disorders.
Methods: Pre-and-post curriculum self-report surveys were administered to 11-14-year-olds (n=28) at the Girls Inc. summer camp. Group C1 consisted of 11-12 year-olds and C2 were 13-14 year-olds. All participants present for the camp the day of surveying were included in the study. Likert scales were used to assess body image and self -esteem. Collins Child Female Scale determined dissonance between current and ideal body image. Data was also collected regarding the use of dieting and exercise to lose weight.
Results: No significant differences were found. In a Likert scale question on body satisfaction, there was no significant difference between pre-and post-curriculum answers (X2(t-1.7056, p=0.1036)). Body dissonance was measured to have no significant difference between pre-and post-curriculum answers (Paired t-test(t=0.8467, p=0.4077)). In a question asking if participants have been on a diet, 41.4% answered yes. This data was compared between two groups, and no significant difference was found (X2(z=0.1357, p=0.7125)) .
Conclusion: This research can be used to aid Girls Inc. and similar programs in updating or creating eating disorder prevention curriculum. Because research has shown that increasing self-esteem and improving body image leads to decreased risk of developing eating disorders, it is important that curriculum aimed at preventing eating disorders is measured for its success in improving these factors.
Effects of kidney disease and dietary inulin treatment on transcellular phosphorus transporters
Authors: Fonseca Austin , Wilson Hannah , Chen Neal X. , Moe Sharon M. , Biruete Annabel 
Published: January 2023

Introduction: Chronic Kidney Disease – mineral bone disorder (CKD-MBD) is marked by biochemical abnormalities, bone alterations, and vascular calcifications. We recently showed that the fermentable fiber inulin lowered circulating phosphorus. Our objective was to determine the effect of dietary inulin on the expression of intestinal phosphate transporters.
Methods: Starting at 22 weeks of age ((~ 50% normal GFR) and for 8-or-10 weeks, normal littermates (NL) and Cy/+ male rats (CKD) were fed a 0.7% phosphorus, casein-based diet without or with 10%-inulin (CKD+IN); At euthanasia (30 or 32 weeks, ~30-to-15% normal GFR), mucosa from duodenum, jejunum, and ileum was collected for intestinal transporter expression (NaPi2b, PiT1, PiT2, NHE3) via qPCR. Data was analyzed via 2-way ANOVA.
Results: CKD animals developed hyperphosphatemia at 32 weeks, but CKD+IN lowered circulating phosphorus. NaPi2b was expressed highest in the jejunum, followed by the duodenum, but not ileum. At 32 weeks, NaPi2b was lower in CKD and CKD+IN in the duodenum and jejunum compared to NL (p<0.05). PiT1 was expressed in all three intestinal segments. Duodenal PiT1 expression was increased in the CKD group compared to NL and CKD+IN (p<0.05), but the expression was unchanged in the jejunum or ileum. PiT2 expression was consistent across all three segments. Duodenal PiT2 expression decreased in CKD and CKD+IN compared to NL (p<0.05). NHE3 expression were highest in jejunum. From 30-to-32 weeks, NL had increased duodenal NHE3 expression (p<0.05), but expression was similar between CKD and CKD+IN in jejunum and ileum.
Conclusions: CKD alters intestinal phosphate transporters, but a 10% Inulin diet did not affect their expression in the small intestine. Lowering circulating phosphorus may be related to improvements in gastrointestinal microbiota, reduction of uremic toxins, and possibly phosphorus transport in the cecum and colon. Furthermore, the effect of inulin on paracellular phosphate absorption in CKD should be explored.
Micronutrient supplementation in pregnancy: a KAP survey with healthcare consultants in India

Published: January 2023

Background: Maternal nutrition during pregnancy is a serious public health issue as it negatively impacts women and their children. The most commonly used nutritional interventions during pregnancy are folic acid and omega-3 fatty acid (n-3 FA). This survey aimed to evaluate the knowledge, attitude and perception towards folic acid, n-3 FA and other supplementation amongst healthcare practitioners (HCPs).
Methods: A close-ended questionnaire-based survey was distributed among obstetricians-gynaecologists and HCPs overlooking pregnant and lactating women between July and September 2022 in India. An excel based survey analysis was performed once the survey completed.
Results: A total of 500 valid questionnaires were collected. Only 55% of them recommended n-3 FA, whereas 45% did not recommend as they believed that the typical Indian diet provides enough n-3 FA and supplements are not necessary. The majority (58.91%) of prescribers prescribed n-3 FA to all pregnant women, followed by older women with a history of abortion and high-risk pregnancy. Both eicosapentaenoic acid and docosahexaenoic acid were favoured in clinical practice. In addition, 56.8% of HCPs recommended folic acid at a dose of 5 mg/day for patients with a bad obstetric history, while 43.2% of HCPs recommended folic acid at a dose of 1 mg/day.
Conclusions: Supplements and adequate nutrition can reduce the likelihood of poor maternal and foetal outcomes in high-risk pregnancies. Nutritional supplementation is a cost-effective and safe risk-reduction method, given the high prevalence of pregnancy complications. However, more knowledge dissemination on n-3 FA supplements, folic acid and micronutrients is essential.

Background: Volar Barton fractures of distal radius almost always require a surgical fixation. Near anatomical reduction and a stout fixation is imperative for good outcome. The present study aimed at studying the outcome of open reduction and internal fixation with volar locking plate for volar Barton fractures.
Methods: The present study included 25 patients with volar Barton fractures of distal radius presenting to the orthopaedic department who were managed with volar locking plate. The minimum follow-up period was 12 months. Wrist movements were recorded and outcome was studied using modified mayo wrist score at final follow-up.
Results: The mean modified mayo wrist score at final follow-up was 88.47±15.3. Excellent to good outcome was observed in 80% of the patients. None of the patients had a poor outcome. Clinically significant movements were observed at wrist at final follow-up. Superficial wound infection was the most common complication and deep infection was seen in two patients and both of them needed early implant removal at three months. Hypertrophic scar at surgical incision site was observed in two patients but did not bother the patients. Two patients needed a stellate ganglion block and physiotherapy for complex regional pain syndrome (CRPS) and both responded well.
Conclusions: Open reduction and internal fixation (ORIF) with volar locking plate provides stout fixation in volar Barton fractures and allows early physiotherapy and rehabilitation of wrist. The results are predictably good in most patients with minimal complications rates.
