The role of formalization and organizational trust as antecedents of ambidexterity: An investigation on the organic agro-food industry
This article investigates the influence of specific key organizational factors (i.e., enabling formalization, coercive formalization, and trust) as antecedents of ambidexterity. Moreover, we propose a new way of operationalizing ambidexterity, under a holistic vision, including the synergies between exploration and exploitation. The study has been developed in the Spanish organic agro-food industry; a total of 239 usable responses were received from two respondents from each company\u2014the general manager and the quality manager. The findings show that enabling formalization and organizational trust are positively related to ambidexterity, but contrary to our predictions, we found no evidence to show that coercive formalization is related to ambidexterity. In turn, we found different results for trust as a moderating factor on the types of formalization and ambidexterity
Subtenon carboplatin in the management of intraocular retinoblastoma
Purpose: To evaluate the efficacy of adjuvant subtenon carboplatin in the management of intraocular retinoblastoma. Methods: This study was conducted as a randomized, double-masked clinical trial. A diagnosis of intraocular retinoblastoma was made based on clinical examination, ultrasonography and orbital CT-scanning. The greatest basal dimension of the tumors was estimated in disc diameter (DD) by indirect ophthalmoscopy. Tumor thickness was determined by ultrasonography. Each eye was assigned to one of 10 blocks based on tumor stage (Reese-Ellsworth classification) and randomly received systemic chemotherapy alone (control group) or systemic chemotherapy plus 20mg subtenon carboplatin (case group). Indirect laser photocoagulation or cryotherapy was performed as additional treatment. Results: The study included 35 tumors in 17 eyes of 14 patients (19 tumors in 8 eyes in the control group and 16 tumors in 9 eyes in the case group). There was 57.22 and 61.73 decrease in tumor thickness in the control and case groups, respectively. This difference was not statistically significant (P=0.12). The decrease in greatest basal tumor dimension in the control group (47.32) was not significantly different from that in the case group (38.80). One eye (12.5) in the control group and 3 eyes (33.3) in the case group were enucleated. Conclusion: Adjuvant subtenon carboplatin does not seem to increase the efficacy of systemic chemotherapy in the treatment of intraocular retinoblastoma
Association between C-reactive protein with all-cause mortality in ELSA-Brasil cohort
Background: High-sensitive C-reactive protein (hsCRP) has been proposed as a marker of incident cardiovascular disease and vascular mortality, and it may also be a marker of non-vascular mortality. However, most evidence comes from either North American or European cohorts. The present proposal aims to investigate the association of high-sensitive C-reactive protein with the risk of all-cause mortality in a multi-ethnic Brazilian population
Methods: Cohort data from baseline (2008–2010) of 14 792 subjects participating in the Brazilian Longitudinal Study of Adult Health were used. HsCRP was assayed with Immunochemistry. The association of baseline covariates with all-cause mortality was calculated by Cox regression for univariate model and adjusted for different confounders after mean follow-up of 8.0 ± 1.1 years. The final model was adjusted for age, sex, self-rated race/ethnicity, schooling, health behaviours and prevalent chronic disease.
Results: The risk of death increased steadily by quartiles of hsCRP from 1.45 (95% Confidence Interval: 1.05, 2.01) in Quartile 2 to 1.95 (1.42, 2.69) in Quartile 4 compared to Quartile 1. Furthermore, the persistence of a significant graded association after the exclusion of deaths in the first year of follow-up suggests that these results are unlikely to be due to reverse causality. Finally, the hazard ratios were unaffected by the exclusion of participants that had self-reported past medical history for diabetes, cancer and chronic obstructive pulmonary disease.
Conclusions: Our study shows that hsCRP levels is associated with mortality in a highly admixed population, independently of a large set of lifestyle and clinical variables
Residuos agroindustriales su impacto, manejo y aprovechamiento
In the agroindustry, the matters are subject adaptation or transformation processes to provide added value through the implementation of unit operations to facilitate consumption, generating one of the major environmental concerns in our environment, the high production of waste. In some cases, these wastes are treated, to reduce the negative impact their emission, discharge or disposal could generate, making them a useful product and added value that solves a problem and generate additional income. In this review, we describe some research developed aimed at harnessing the waste generated in agribusiness.En la agroindustria, las materias primas son sometidas a procesos de adecuación o transformación para darle valor agregado, mediante la implementación de operaciones unitarias para facilitar su consumo; generando una de las principales problemáticas ambientales en nuestro medio, la alta producción de residuos. En algunos casos estos residuos son tratados; hasta reducir el impacto negativo que su emisión, vertimiento o disposición pudiera generar; convirtiéndolos en un producto útil y de mayor valor agregado que solucione una problemática y genere ingresos económicos adicionales. En esta revisión se describen algunas investigaciones desarrolladas tendientes al aprovechamiento de los residuos generados en las agroindustrias
Prediction of survival for patients with pemphigus vulgaris and pemphigus foliaceus: a retrospective cohort study
Early invasive vulvar squamous cell carcinoma arising in a woman with vulvar pemphigus vulgaris and systemic lupus erythematosus
Pemphigus vulgaris (PV) is an autoimmune blistering disease of the skin and mucous membranes. Genital involvement occurs when most other common sites are concurrently affected or are in remission. Systemic lupus erythematosus (SLE) is an autoimmune disease that may affect many parts of the body and the skin with occasional bullous lesions. Pemphigus vulgaris and SLE may be associated, albeit rarely. Here, we report the first case of a woman affected with SLE presenting with early invasive squamous cell carcinoma (SCC) arising from Pemphigus Vulgaris of the vulva
Professional development and sustainable development goals
Professional development is defined as a consciously designed systematic process that helps professionals to attain, utilize, and retain knowledge, skills, and expertise. It is simply a process of obtaining skills, qualifications, and experience that help in advancement in one’s career. In the field of education, it is defined as the process of improving staff skills and competencies needed to produce outstanding performance of students. It also refers to a process of improving an organization’s staff capabilities through access to education and training opportunities for better output. Professional
development can include a variety of approaches such as formal and informal education, vocational, specialized, or skill-based training, or advanced professional learning
Protective versus pathogenic anti-CD4 immunity: insights from the study of natural resistance to HIV infection
HIV-1 exposure causes several dramatic unbalances in the immune system homeostasis. Here, we will focus on the paradox whereby CD4 specific autoimmune responses, which are expected to contribute to the catastrophic loss of most part of the T helper lymphocyte subset in infected patients, may display the characteristics of an unconventional protective immunity in individuals naturally resistant to HIV-1 infection. Reference to differences in fine epitope mapping of these two oppositely polarized outcomes will be presented, with particular reference to partially or totally CD4-gp120 complex-specific antibodies. The fine tuning of the anti-self immune response to the HIV-1 receptor may determine whether viral exposure will result in infection or, alternatively, protective immunity
Diagnostic techniques for inflammatory eye disease: past, present and future: a review
Investigations used to aid diagnosis and prognosticate outcomes in ocular inflammatory disorders are based on techniques that have evolved over the last two centuries have dramatically evolved with the advances in molecular biological and imaging technology. Our improved understanding of basic biological processes of infective drives of innate immunity bridging the engagement of adaptive immunity have formed techniques to tailor and develop assays, and deliver targeted treatment options. Diagnostic techniques are paramount to distinguish infective from non-infective intraocular inflammatory disease, particularly in atypical cases. The advances have enabled our ability to multiplex assay small amount of specimen quantities of intraocular samples including aqueous, vitreous or small tissue samples. Nevertheless to achieve diagnosis, techniques often require a range of assays from traditional hypersensitivity reactions and microbe specific immunoglobulin analysis to modern molecular techniques and cytokine analysis. Such approaches capitalise on the advantages of each technique, thereby improving the sensitivity and specificity of diagnoses. This review article highlights the development of laboratory diagnostic techniques for intraocular inflammatory disorders now readily available to assist in accurate identification of infective agents and appropriation of appropriate therapies as well as formulating patient stratification alongside clinical diagnoses into disease groups for clinical trials
