Comunicación, sentido y vida cotidiana

La pregunta por la vida cotidiana, su estructura, su funcionamiento, no es una novedad en el ámbito de las ciencias sociales. Se han ocupado de esta problemática pensadores de la talla de Heller, Habermas, Goffman, Freiré, Wolf, por citar sólo algunos. Diferentes enfoques, teorías y preocupaciones han derivado en un vasto campo de estudio que observa y rescata lo que era considerado como "materiales secundarios", indagando cómo los pequeñísimos actos cotidianos realzan temas muy importantes (Wolf, 1979). En el campo de la comunicación cobran fuerza en cantidad y calidad, a partir de 1980 (Fuentes, 1991) los estudios que abordan diferentes aspectos de la cotidianidad para indagar por ejemplo, en un cambio de perspectiva, no ya lo que los medios hacen a la gente, sino lo que la gente hace con y a partir de los medios, haciendo aparecer en primer plano al actor de la comunicación.ITESO, A.C

Demographics and serological profile of blood donors who opt for the confidential unit exclusion in a blood bank in Sao Paulo, Brazil

Blood transfusion is still an irreplaceable therapeutic modality, widely applied to medical care. Clinical interviews and laboratory testing for transfusion-transmitted infections (TTI) are routinely performed to prevent TTI among the recipients. However, there is still a residual risk of TTI, and some blood banks have adopted the confidential unit exclusion (CUE) as an additional safety strategy. In this study, we investigated the demographic characteristics and laboratory results of the screening of TTI among blood donors who opted for the CUE, compared to blood donors who did not opt for the CUE. In this study, we included 32,261 blood donations collected in a single blood bank in Sao Paulo, Brazil. A very small proportion of donors (0.25%) opted for the CUE. They were mainly single males and were more likely to have HBV, syphilis, and other positive results in the combined screening for TTI, in comparison with those who did not opt for the CUE. This difference was statistically significant in both the univariable and the multivariable analysis adjusted for age, gender , marital status and years of schooling. Our findings highlight that CUE may be a useful tool to improve the safety for blood recipients, but its efficiency is context-dependent

Cognitive stimulation as alternative treatment to improve psychological disorders in patients with mild cognitive impairment

(1) Background: Mild cognitive impairment is becoming one of the most common clinical manifestations affecting older people. For this reason, developing non-pharmacological strategies to help improve or maintain the physical condition of patients with mild dementia has become a priority. Therefore, the objective of this study is to provide evidence about the effects of a cognitive stimulation program on cognitive performance, anxiety, depression, and quality of life in people with mild cognitive impairment (MCI) and aged > 70. (2) Methods: This study is a randomized clinical trial. A total of 72 elderly people with MCI participated: 35 in the control group who did not receive any intervention and 36 in the experimental group who received a cognitive stimulation program for 12 weeks. Cognitive performance, depression, anxiety and health-related quality of life (HRQoL) were measured using the Mini-Mental State Examination (MMSE), the Yesavage Geriatric Depression Scale, the Hamilton Rating Scale, and the SF-12, respectively. (3) Results: In the experimental group, significant results were obtained on cognitive performance, depression, anxiety and general health, emotional role, social functioning, vitality, mental health and mental component summary domains of the SF-12. (4) Conclusions: a cognitive stimulation program of 12 weeks improves cognitive performance, anxiety, depression, and HRQoL in people with MCI aged > 70
