Introduction: The incidence of cancer increases as age progresses. With aging, and with a chronic disease such as cancer, the prevalence of disease-related malnutrition (DRE), sarcopenia, cachexia and frailty increases. These are associated with mortality, toxicity due to antineoplastic treatment and post-surgical complications. In this article, the prevalence of DRE, sarcopenia and cachexia, the way to diagnose these situations in the daily clinic, their pathophysiology, their relationship with clinical prognosis, and the evidence on the effectiveness of medical nutrition treatment and multimodal therapy, with physical exercise as the main ally, are reviewed differentially in older patients. At the moment, there are few guidelines that refer only to the elderly patient, and until more studies are generated in this group of patients, the actions, in matters of nutrition, should be based on those already published in general oncology. If the elderly patient has malnutrition, and this can condition quality of life or clinical prognosis, medical nutrition therapy should progress, individually, from dietary advice to more complex forms of treatment such as oral supplementation, enteral nutrition or parenteral nutrition.

An immobilized chiral bifunctional iminophosphorane superbase organocatalyst has been developed and applied in a range of challenging enantioselective reactions. A unique feature of this novel catalytic system is that the final step creation of the iminophosphorane occurs at the point of immobilization. The utility of the immobilized catalyst system was demonstrated in the nitro-Mannich reaction of ketimines as well as the conjugate addition of high pKa 1,3-dicarbonyl pro-nucleophiles to nitrostyrene. Catalyst recycling was also demonstrated.

The design, synthesis, and development of a new class of modular, strongly basic, and tunable bifunctional Brønsted base/H-bond-donor organocatalysts are reported. These catalysts incorporate a triaryliminophosphorane as the Brønsted basic moiety and are readily synthesized via a last step Staudinger reaction of a chiral organoazide and a triarylphosphine. Their application to the first general enantioselective organocatalytic nitro-Mannich reaction of nitromethane to unactivated ketone-derived imines allows the enantioselective construction of β-nitroamines possessing a fully substituted carbon atom. The reaction is amenable to multigram scale-up, and the products are useful for the synthesis of enantiopure 1,2-diamine and α-amino acid derivatives.

The synthesis of a new chiral pyrrolidine has been performed using 2,3-O-isopropylidene-D-erythronolactol as a suitable starting material.

Objective: To assess if work-related activities represented a threatening situation for nursing personnel through the correlation between the level of usual anxiety (trait-anxiety) and the level of anxiety present during working hours (state-anxiety). As well as, to determine state-anxiety risk factors., Material and Methods: The state-trait-anxiety inventory was administered to 285 nurses of a health care institution chosen at random., Results: The correlation coefficient was 0.53 (CI 95% = 0.43, 0.60, p = 0.001), after controlling for age, marital status, number of children, workload, service, category, level of care, years of service and personal relationships. Negative personal relationships and = 1 year of service influenced the level of anxiety present during working hours (beta = -0.21, beta = -0.24, p = 0.001, respectively)., Conclusions: Work-related activities represented a threatening situation and contributed to anxiety. It is necessary to recognize anxiety work-related risk factors for developing coping strategies and preventing well-being damage.
