RESUMEN

Unintentional weight loss and Undernutrition are major problems among older people living in Long-Term Care Facilities (LTCF). Undernutrition manifests in LTCF particularly as weight loss and low Body Mass Index (BMI) and is associated with increased morbidity and mortality as well as with functional decline. There are many factors associated with poor nutritional status and affecting protein-energy intake and/or energy expenditure. These include age of 85 years or older, low nutrient intake, loss of ability to eat independently, swallowing and chewing difficulties, becoming bed-ridden, pressure ulcers, history of hip fracture, dementia, depressive symptoms and suffering from two or more chronic illnesses. Nutritional evaluation is an essential part of the Comprehensive Geriatric Assessment (CGA). This evaluation ranges from methods such as BMI to several validated tools such as Mini-Nutritional Assessment (MNA). After diagnosis, the management of undernutrition in LTCF requires a multidisciplinary approach which may involve dietary and environmental improvements and managing multiple co-morbidities, while avoiding polypharmacy as far as possible. Finally, the need for supplementation or artificial (tube) feeding may be considered taking into account the CGA and individual needs. This document presents a succinct review and recommendations of evaluation and treatment of undernutrition.

RESUMEN

A series of new cortexolone-related derivatives has been synthesized and investigated for potential anti-androgenic activity. Among the steroids evaluated, 9,11-dehydrocortexolone 17alpha-butyrate (CB-03-04) was the most promising one. The compound displayed a strong local antiandrogenic activity in hamster's flank organ test, and it was also found to be effective in the rat after subcutaneous injection. When compared to other well known androgen antagonists, the rank order of topical anti-androgenic activity in that test was: cyproterone acetate (CAS 427-51-0) > or = CB-03-04 > finasteride (CAS 98319-26-7) > flutamide (CAS 13311-84-7). In addition, the steroid had selective antigonadotropic activity, when injected into parabiotic rats, and was about as active as progesterone. The activity of CB-03-04 was ascribed mainly to its ability to compete with the stimulating effects of testosterone and dihydrotestosterone and, concurrently, to inhibit the gonadotropins hypersecretion. This bimodal mechanism of action could be predictive for the clinical usefulness of the steroid in the treatment of prostate cancer and benign prostate hypertrophy.

RESUMEN

The aim of this study was to investigate the antiandrogenic activity of a new monoester of cortexolone, cortexolone 17alpha-propionate (CAS 19608-29-8, CB-03-01). Although the compound displayed a strong local antiandrogenic activity in hamster's flank organ test, it did not exhibit antiandrogenic activity in rats after subcutaneous injection, nor did it affect gonadotropins hypersecretion when injected to parabiotic rats. As topical antiandrogen, the steroid resulted about 4 times more active than progesterone (CAS 57-83-0) and, when compared to known antiandrogen standards, it was about 3 times more potent than flutamide (CAS 13311-84-7), about 2 times more effective than finasteride (CAS 98319-26-7) and approximately as active as cyproterone acetate (CAS 427-51-0). Its pharmacological activity seemed to be primarily related to its ability to antagonistically compete at androgen receptor level; nevertheless its primary pharmacological target needs to be further investigated. Its topical activity, along with the apparent absence of systemic effects, anticipates this compound to have the potential of representing a novel and safe therapeutic approach for androgen-dependent skin disorders.
