Psychosocial Working Conditions and Well-Being of Migrant Workers in Spain.

This study examines the relationship beween employment and psychosocial working conditions and well-being of native and migrant workers in the working population of Spain. Data from the 7th Spanish Survey of Working Conditions was used to conduct a confirmatory factor analysis (n = 8508) to identify the main latent variables that influenced well-being. Using structural equation modeling and multivariate analysis, we found different patterns and perceptions of well-being and working conditions in these two groups.

Recurrence of liver metastases from colorectal cancer and repeat liver resection.

Objective: The purpose of this study was to assess the resectability and effectiveness of repeat hepatectomy for relapsing liver metastases of colorectal origin in terms of morbidity, mortality, overall survival, and disease-free survival.

Methods: A retrospective study was performed on a prospective cohort of patients with colorectal liver metastases who underwent repeat surgery at Hospital Universitario San Cecilio, Granada (Spain), from March 2003 to June 2013. Primary outcome variables included survival and morbidity within 30 days post-surgery.

[Analysis of food intake and dietary habits in a population of adolescents in the city of Granada (Spain)].

Objectives: The main research objective was to analyze the intake of macronutrients and micronutrients in a population of adolescents. The purpose of the study was to verify a significant correlation between the habit of breafasting at home each morning and the nutritional status of the sample population.

Sample And Methodology: The sample population was composed of 100 adolescents, 12-15 years of age, who attended two public secondary schools in the city of Granada.

[Influence of nutritional status, hormones serum levels, and family history on breast cancer development].

Background: Several studies have analyzed the relation between obesity and the hormonal imbalances generated by overweight and a family history of breast cancer. All of these factors are potentially implicated in the early development of breast cancer.

Aim: To verify the existence of a significant relation between the nutritional status of breast cancer patients, their hormone serum levels (estrogens, prolactin, and progesterone), and the existence of a family history of breast cancer.

[Leptin: a peptide with therapeutic potential in the obese].

Obesity is the result of a positive balance between total energy intake and its catabolism. Although many factors are involved in the regulation of energy metabolism, the discovery of leptin led to energy homeostasis being investigated in greater depth. Since its identification, leptin has been considered important in the development of obesity, given its anorexigenic effect and influence on food intake and energy expenditure.
