Responsabilidad Social Empresaria en su dimensión laboral
No full textA partir del presente trabajo me propuse hacer un análisis sobre la manera en que la responsabilidad social empresaria influye en el ámbito laboral, ya sea a partir de las propias políticas de contratación de las empresas, la promoción de la investigación científica y académica o la capacitación.
En este comentario analítico no se pretende hacer un estudio normativo de profundidad respecto de la responsabilidad social empresaria, sino enfocar la misma desde situaciones reales en las que las empresas influyen en la faz laboral, dándole un contraste normativ
O regime legal e a concessão de títulos de criador no México
No full textEste artículo analiza la implementación del régimen jurídico de protección de variedades vegetales en México y el proceso de concesión de los títulos de obtentor. Partimos de la caracterización de la agricultura mexicana presentando un panorama dicotómico: de un lado, la agricultura tradicional; de otro, la agricultura comercial. Como siguiente punto, la implementación del sistema de variedades vegetales como parte de los cambios en la economía en las décadas de 1980 y 1990, cuando el Estado dejó de intervenir en la actividad agrícola y acometió un proceso de liberalización comercial. Posteriormente, estudiamos la pieza fundamental de este cambio: los tratados internacionales que obligan a México a proteger las variedades vegetales y el Convenio Internacional para la Protección de Obtenciones Vegetales. También examinamos brevemente acuerdos en los que se limita la propiedad industrial, así como la regulación constitucional y su interpretación, que permitiría equilibrar los intereses de todas las partes implicadas. Después, revisamos el régimen jurídico de la Ley Federal de Variedades Vegetales y su Reglamento y ponemos énfasis en los límites a los derechos del obtentor, así como a la protección de la biodiversidad. Estudiamos la estructura administrativa involucrada en el procedimiento de concesión de los títulos de obtentor y, por último, dicho proceso desde la solicitud hasta la concesión del título de obtentor.This article analyses the implementation of the Legal Regime of protection of plant varieties in Mexico and the procedure of concession of title deeds. The starting point is the description of the Mexican agriculture offering a dichotomous panorama; traditional agriculture on one hand, and on the other, the commercial agriculture. It is followed by the study of the implementation of the plant variety system as part of the economy changes of the decade 1980 and 1990, period in which the Mexican State stops participating in the agricultural activity and undertakes a commercial discharge. Following with the study of one of the key elements of this change, the international trades that obligate Mexico to protect the plant varieties and The International Agreement for the Protection of the Plant Breeders. Briefly, the agreements in which the industrial property is limited is examined as well as its constitutional regulations and its interpretation that allows to balance the interests of all the involved parties. Following with a review of the Legal Regime the Federal Law of Plan Varieties and its Regulation. The limits of the Plant Breeders rights is emphasized, as well as the protection of the biodiversity. The administrative structure involved in the procedure of concession of plant breeders’ deeds and, the whole process, from the application to the obtention of the plant breeders’ deeds is studied.Este artigo analisa a implementação do regime jurídico de proteção de variedades vegetais no México e o processo de concessão de títulos de melhorista.

Chronic Kidney Disease and Arterial Stiffness: A Two-Way Path
No full textDisponible en: https://www.frontiersin.org/articles/10.3389/fmed.2021.765924/fullAbstract
The kidney-heart relationship has raised interest for the medical population since its vast and complex interaction significantly impacts health. Chronic kidney disease (CKD) generates vascular structure and function changes, with significant hemodynamic effects. The early arterial stiffening in CKD patients is a consequence of the interaction between oxidative stress and chronic vascular inflammation, leading to an accelerated deterioration of left ventricular function and alteration in tissue perfusion. CKD amplifies the inflammatory cascade's activation and is responsible for altering the endothelium function, increasing the vascular tone, wall thickening, and favors calcium deposits in the arterial wall. Simultaneously, the autonomic imbalance, and alteration in other hormonal systems, also favor the overactivation of inflammatory and fibrotic mediators. Thus, hormonal disarrangement also contributes to structural and functional lesions throughout the arterial wall. On the other hand, a rise in arterial stiffening and volume overload generates high left ventricular afterload. It increases the left ventricular burden with consequent myocardial remodeling, development of left ventricular hypertrophy and, in turn, heart failure. It is noteworthy that reduction in glomerular mass of renal diseases generates a compensatory glomerular filtration overdriven associated with large-arteries stiffness and high cardiovascular events. Furthermore, we consider that the consequent alterations of the arterial system's mechanical properties are crucial for altering tissue perfusion, mainly in low resistance. Thus, increasing the knowledge of these processes may help the reader to integrate them from a pathophysiological perspective, providing a comprehensive idea of this two-way path between arterial stiffness and renal dysfunction and their impact at the cardiovascular level.
Keywords: CKD progression; calcification; cardiovascular events; pulsatility; pulse wave velocity (PWV).

No full textDisponible en: https://www.sciencedirect.com/science/article/abs/pii/S1268773120302010?via%3DihubAbstract
Background: Ankle fractures are the most common traumatic bone injuries of the lower limb. Over 50% of ankle fractures occur at the syndesmosis level (type AO B). The goal of treatment is to achieve an anatomical reduction and appropriate stabilization. The present study aimed to evaluate the clinical-functional and radiological results, and complications of minimally invasive reduction and fixation technique for ankle fractures type AO B. The surgical technique also is detailed.
Material and methods: A prospective analysis of 451 patients undergoing surgery for type AO B displaced ankle fracture was performed. All patients were treated with minimally invasive surgery. The following times were recorded: time between trauma and osteosynthesis, hospitalization length, surgical time, and exposure time to fluoroscopy. Age and gender, mechanism of injury, and characteristics of fractures were recorded. For functional outcome, AOFAS score, VAS, and Weber score were used. Radiographic analysis was performed. The average follow-up was 112 months.
Results: Mean age was 48.2 years old. Average length of stay in hospital was 5.72 h. Mean duration of the surgery was 32.8 min. Average fluoroscopic exposure time during surgery was 9.25 s. Mean bone union time was 38.2 days. Weber's score was on average 1.5/24 points and the long-term follow-up AOFAS score was on average 97.5/100. Postoperative complications incidence was 2.7%.
Conclusions: Distal fibula fixation with the MIPO technique presented good functional outcomes and could be helpful in the avoidance of the complications associated with conventional open reduction and internal fixation. However, it needs more exposition to intraoperative fluoroscopy.
Level of evidence: II.
Keywords: Ankle fractures; Fibula; MIPO; Minimally invasive surgery.

Hepatitis B virus vaccine and chronic kidney disease. The advances
No full textDisponible en: https://www.revistanefrologia.com/es-linkresolver-hepatitis-b-virus-vaccine-chronic-S2013251421000432Abstract
Background: Hepatitis B is an important agent of liver disease in patients with chronic kidney disease and chronic HBV infection promotes the development of CKD in the adult general population. Patients with CKD have a suboptimal response to various vaccines, and it remains unclear how we boost the immune response of CKD patients to HB vaccine.
Study aims and design: We performed a narrative review to assess the mechanisms of lower immunogenicity of HBV vaccine in CKD population; multiple approaches to improve the response rate of CKD patients to HBV vaccine have been reported. This is a very important topic for nephrologists who often serve as primary case providers for patients with CKD.
Results: The recommended vaccine schedule for CKD patients including those on maintenance dialysis is based on recombinant vaccine, four doses (month 0,1,2, and 6; 40mcg each) by intramuscular route (deltoid muscle). According to RCTs or observational studies, some recombinant vaccines with adjuvants (i.e., HBV-AS02 and HBV-AS04) look promising. HBV-AS04 showed to give better seroprotection rates and durable immune response over extended follow-ups compared with licensed HBV vaccine in CKD patients. The seroprotection rate was 95% (97/102) and 82% (202/248) in pre-dialysis and dialysis patients, respectively, one month after completing vaccine schedule with HBV-AS04. HBV-AS02 was superior to licensed vaccine in terms of seroprotection rate, 76.9% vs. 37.6%.
Conclusions: We suggest adjuvanted recombinant (HBV-AS04) vaccine (0,1,2 and 3 months; 20 mcg each dose) and post vaccination testing of anti-HBs antibody after vaccination. Booster doses to patients whose anti-HBs titers fall below the seroprotection level (<10IU/mL) during the follow-up are appropriate. The patho-physiologic mechanisms responsible for the poor immunogenicity of HBV vaccine in CKD patients are under active investigation.
