This study compared the outcomes of metastatic breast cancer in patients with imaging-diagnosed pseudocirrhosis with or without pHTN. Methods: The medical records from patients with metastatic breast cancer and pseudocirrhosis between 2005 and 2017 were retrospectively analyzed. Clinical pHTN was defined based on endoscopic evidence of esophageal or gastric varices. Results: Among 106 patients with pseudocirrhosis, 33 (31%) had de novo stage IV disease, and 66 (62%) had hormone receptor (HR)–positive and human epidermal growth factor receptor 2 (HER2)–negative breast cancer. In total, 81 (76%) had initial metastases in both hepatic lobes, 91 (86%) had 4 or more liver metastases, and 32 (30%) had pHTN. The median overall survival (OS) was 5 and 13 months in patients with and without pHTN, respectivel...

Therefore, it is important to interrelate the environment and economy to generate an environmental commitment by industries. Green accounting arises with the aims of providing quantitative and qualitative information on the company's environmental aspects. This paper describes the current state of green accounting in the leading mining companies in Colombia according to the Ministry of Energy and Mines of Colombia. Findings show that 80% of the selected mining companies integrate green accounting in their management system. However, the underlying procedures are not always put into practice. Therefore, accounting studies must lead to the development of an environmental accounting model and the implementation of mandatory regulations for green accounting.

Los datos obtenidos mostraron que las dosis antidepresivas 16, 32, 64 mg/kg (i.p.) presentan efecto analgésico y una respuesta ansiolítica, sin resultado significativo en el modelo de memoria espacial, pero con una disminución en la actividad realizada en la memoria de trabajo para la dosis de 64 mg/kg (i.p.). Esto evidencia que fluoxetina puede orientar mayor eficacia a dosis con efecto antidepresivo e indica un efecto analgésico y ansiolítico sin producir cambio en la actividad motora del ratón. La dosis máxima investigada provocó variación en su actividad motora lo cual permite concluir que ISRS "fluoxetina" tiene un posible efecto sedativo.

Taking into account the proved evidence that deficits in processing emotional information shows difficulties in executive functions and social behavior, the present work aims to compare the perceptual and dimensional similarities between the emotions transmitted by the faces (facial emotions) and those typically associated with two particular emotional contexts (offenders and non-offenders). To evaluate the contextual influence on emotional face categorization, the emotional recognition in 69 male young (35 offenders (17.22 ± 1.5 years) and 34 non-offenders (16.90 ± 1.56 years) from Barranquilla (Colombia) was analyzed. Experimental results displayed significant differences among the two groups, mainly focused in the recognition of anger and disgust faces. In this sense, the analysis of abovementioned data may lead to the development of more specific and cost-effective therapeutic treatments for offender population.

CP was the reply of the industry to the call for sustainable development as launched by the WCED (1987) and further elaborated in Rio's Agenda 21 (UN, 1992). During the past 25 years, the concept was put in practice. During this period it changed in scope, methods, and application area. This provided a deeper socio-economic impact to an idea that was originally launched to awaken industry on its environmental responsibilities. This paper provides a review of essentials that contributed to the fundamental changes in CP during the most recent quarter of a century. It takes off with a review of CP definitions illustrating the changes of the content. Changes in scope are exemplified with the increasing importance of "Corporate Social Responsibility" (CSR). This includes that post-modern companies have not only responsibilities on their economic performance and the environment, but should also act on issues including human rights and resources, business ethics, and community involvement. The links between CP and green and circular economy are indicated. The CP approach is increasingly applied outside the industry. CP for sustainable tourism is discussed in more detail but is only an example of the wider application in e.g. agriculture or health services.

This research aimed to study the acute effect of 400 mg of caffeine monohydrate on the psycho-physiological response and rifle marksmanship of warfighters during a close quarter combat simulation. We analysed parameter of heart rate, blood lactate, cortical arousal, state anxiety and marksmanship of 20 Spanish Army veteran warfighters before and after a close quarter combat simulation in a double-blind procedure, also a correlation analysis was conducted between all the study variables. Marksmanship of warfighters did not improve with the caffeine ingestion, but it produced an increase in blood lactate concentration (caffeine: 1.9 ± 0.5 vs. 9.2 ± 1.1 mmol.l; placebo: 1.8 ± 0.7 vs. 6.9 ± 2.2 mmol.l), cortical arousal (% of change: caffeine: 2.51; placebo: -1.96) and heart rate (caffeine: 80.0 ± 7.2...

Psychophysiological response and fine motor skills in high-altitude parachute jumps. High Alt Med Biol 18:392-399, 2017.-We analyzed the psychophysiological response and specific fine motor skill of an experienced jumper in HALO (high altitude low opening) and HAHO (high altitude high opening) parachute jumps. Eight HALO and eight HAHO jumpers were analyzed. They jumped at 5500 m, HALO jumpers opened the parachute at 500 m and HAHO jumpers at 4300 m of altitude. Before and after the jumps, parameters of muscle strength, cortical arousal, blood creatine kinase (CK) and glucose, blood oxygen saturation, rate of perceived exertion (RPE), and specific fine motor skills of an experienced jumper were assessed; during the jump, heart rate (HR), HR variability, and speed were evaluated. HALO and HAHO jumps produced a significant increase in CK, lactate, and RPE, ...

A sample of 373 participants was split into two groups and two experimental conditions (products with Swiss symbols and products without Swiss symbols). One group of participants rated the packaging without a Swiss flag and the other one rated the same packaging with a Swiss flag. A semantic differential scale and the Self-Assessment Manikin (SAM) were used to assess attitudes toward the products. Results confirm that there are differences between the two independent groups and that nationality has an effect on product perception and evaluation. Visual symbols such as a country flag can lead to a better product perception and evaluation. Finally, implications for research are discussed.

This sample has been calculated with 95% confidence and a 4.78% of sampling error. For this purpose a Likert Scale was designed to evaluate the components of practices, beliefs and feelings that people have against environmental conservation and sustainable use of water utilities and electrical energy. The results allow to identify that there are significant differences within the practices, beliefs and feelings related to proenvironmental behavior and consumption of public services of water and electrical energy, as well as direct and inverse statistically significant relationships were observed between the three levels attitudinal evaluation. These results are the basis for formulating policies to promote pro-environmental behavior oriented with the responsible and sustainable public services of water and electrical energy use. The responsible consumption of non-renewable resources must begin to intervene from the vital space, on the basis of the dynamics in the home with the assessment and development of pro-environmental practices of sustainable consumption of the household public services of water and electrical energy.
