Spiritual well-being, distress and quality of life in Hispanic women diagnosed with cancer undergoing treatment with chemotherapy.

OBJECTIVE: Previous studies have examined whether spiritual well-being is associated with cancer outcomes, but minority populations are under-represented. This study examines associations of baseline spiritual well-being and change in spiritual well-being with change in distress and quality of life, and explores potential factors associated with changes in spiritual well-being among Hispanic women undergoing chemotherapy. METHODS: Participants completed measures examining spiritual well-being, distress, and quality of life prior to beginning chemotherapy and at weeks 7 and 13. Participants' acculturation and sociodemographic data were collected prior to treatment. Mixed models were used to examine the association of baseline spiritual well-being and change in spiritual well-being during treatment with change in distress and quality of life, and to explore whether sociodemographic factors, acculturation and clinical variables were associated with change in spiritual well-being. RESULTS: A total of 242 participants provided data. Greater baseline spiritual well-being was associated with less concurrent distress and better quality of life (p < 0.001), as well as with greater emotional and functional well-being over time (p values < 0.01). Increases in spiritual well-being were associated with improved social well-being during treatment, whereas decreases in spiritual well-being were associated with worsened social well-being (p < 0.01). Married participants reported greater spiritual well-being at baseline relative to non-married participants (p < 0.001). CONCLUSIONS: Greater spiritual well-being is associated with less concurrent distress and better quality of life, as well as with greater emotional, functional, and social well-being over time among Hispanic women undergoing chemotherapy. Future work could include developing culturally targeted spiritual interventions to improve survivors' well-being.

Depression, Anxiety, and Social Environmental Adversity as Potential Modulators of the Immune Tumor Microenvironment in Breast Cancer Patients.

Background: Mounting data suggest that exposure to chronic stress is associated with worse breast cancer outcomes. This study aimed to explore the impact of social environmental adversity (SEA, e.g., child abuse, crime, sexual, and physical violence), depressive symptomatology, and anxiety on immune cell infiltration into the breast tumor microenvironment. Methods: Participants (n = 33) completed a series of surveys assessing depression and anxiety symptoms, adverse childhood events (ACE), and trauma history. Tumor-associated macrophages (CD68+), B cells (CD19+), and T cells (CD3+) were identified by immunohistochemical analyses of formalin-fixed paraffin-embedded tumor samples and quantified. Spearman rank tests were used to explore the relationships between the variables studied. Results: Exposure to SEA was high (ACE = 72%, exposure to crime = 47%, and exposure to physical/sexual assault = 73%) among participants. Moreover, 30% reported a comorbid history of depression and ACE; 39% reported one or more traumatic events, and clinically significant depression symptomatology, while 21% reported trauma history and significant anxiety symptomatology. Increased tumor-infiltrating B cells were significantly correlated with exposure to crime, anxiety symptoms, and exposure to an ACE. The ACE plus anxiety group presented the highest infiltration of B cells, T cells, and macrophages. Conclusion: These findings support a role for SEA, anxiety symptoms, and depression as potential modulators of the immune tumor microenvironment in breast cancer.

Experimental model standardizing polyvinyl alcohol hydrogel to simulate endoscopic ultrasound and endoscopic ultrasound-elastography.

BACKGROUND: Endoscopic ultrasound (EUS) and endoscopic ultrasound elastography (EUS-E) simulation lessens the learning curve; however, models lack realism, diminishing competitiveness. AIM: To standardize the mechanical properties of polyvinyl alcohol (PVA) hydrogel for simulating organs and digestive lesions. METHODS: PVA hydrogel (Sigma Aldrich, degree of hydrolysis 99%) for simulating EUS/EUS-E lesions was investigated in Unidad de Investigación y Desarrollo Tecnológico at Hospital General de México "Dr. Eduardo Liceaga", Mexico City. We evaluated physical, contrast, elasticity and deformation coefficient characteristics in lesions, applying Kappa's concordance and satisfaction questionnaire (Likert 4-points). RESULTS: PVA hydrogel showed stable mechanical properties. Density depended on molecular weight (MW) and concentration (C). PVA bblocks with the greatest density showed lowest tensile strength (r = -0.8, P = 0.01). Lesions were EUS-graphically visible. Homogeneous and heterogeneous examples were created from PVA blocks or PVA phantoms, exceeding (MW2 = 146000-186000, C9 = 15% and C10 = 20%) with a density under (MW1 = 85000-124000, C1 = 7% and C2 = 9%). We calculated elasticity and deformation parameters of solid (blue) areas, contrasting with the norm (Kappa = 0.8; high degree of satisfaction). CONCLUSION: PVA hydrogels were appropriate for simulating organs and digestive lesions using EUS/EUS-E, facilitating practice and reducing risk. Repetition amplified skills, while reducing the learning curve.

Rapid sequence modification in the highly polymorphic region (HPR) of the hemagglutinin gene of the infectious salmon anaemia virus (ISAV) suggests intra-segmental template switching recombination.

The ISAV has a genome composed of eight segments of (-)ssRNA, segment 6 codes for the hemagglutinin-esterase protein, and has the most variable region of the genome, the highly polymorphic region (HPR), which is unique among orthomyxoviruses. The HPR has been associated with virulence, infectivity and pathogenicity. The full length of the HPR is called HPR0 and the strain with this HPR is avirulent, in contrast to strains with deleted HPR that are virulent to varying degrees. The molecular mechanism that gives rise to the different HPRs remains unclear. Here, we studied in vitro the evolution of reassortant recombinant ISAV (rISAV) in Atlantic salmon head kidney (ASK) cells. To this end, we rescued and cultivated a set of rISAV with different segment 6-HPR genotypes using a reverse genetics system and then sequencing HPR regions of the viruses. Our results show rapid multiple recombination events in ISAV, with sequence insertions and deletions in the HPR, indicating a dynamic process. Inserted sequences can be found in four segments of the ISAV genome (segments 1, 5, 6, and 8). The results suggest intra-segmental heterologous recombination, probably by class I and class II template switching, similar to the proposed segment 5 recombination mechanism.

Estudio transversal de los determinantes del trabajo infantil en Cartagena, año 2007 / Estudo transversal dos determinantes do trabalho infantil em Cartagena, ano 2007 / Transversal study of determinants of child labor in Cartagena, year 2007

El trabajo infantil constituye una problemática compleja que tiene importantes repercusiones en las reservas de capital humano, en la salud de los niños y niñas, y en la persistencia de la pobreza. Nuestro principal objetivo en este artículo es dilucidar sus determinantes en la ciudad de Cartagena a través de la estimación de un modelo probit bivariado, con el cual analizamos conjuntamente las decisiones de trabajo y de asistencia escolar. Los resultados muestran que el trabajo infantil y la asistencia escolar son actividades excluyentes, siendo los determinantes más robustos de estas decisiones la educación del jefe de hogar, y la pobreza. Entre otros determinantes se encuentran las restricciones crediticias, la proximidad física a las escuelas y la tasa de ocupación de las personas adulta.

Child labor is a complex issue with crucial consequences in human capital reserve, children´s health and persistence of poverty. The main aim of this article is to elucidate its determinants in Cartagena through the estimation of a bivariate probit model, which allows analyzing joint decision of schooling attendance and child labor. The findings show that schooling attendance and child labor are exclusives, being the most important determinants the education of the head of household and poverty. Among other determinants they were found credit restrictions, proximity to schools and the occupancy rate of the adults.
