Mild Cognitive Impairment (MCI) is a heterogeneous condition between normal aging and dementia. Upon neuropsychological testing, MCI can be divided into four groups: singledomain amnestic MCI (sd-aMCI), multiple-domain amnestic MCI (md-aMCI), single-and multiple-domain non-amnestic MCI (sd-naMCI, md-naMCI). Some controversy exists about whether the risk of progression to Alzheimer's disease (risk-AD) is increased in all MCI subtypes. We meta-analyzed the risk-AD for four MCI groups using random-effects metaregression with the Hierarchical Robust Variance Estimator and sample size, criterion for objective cognitive impairment, length of follow-up and source of recruitment as covariates. From a pool of 134 available studies, 81 groups from 33 studies (N = 4,907) were metaanalyzed. All the studies were rated as having a high risk of bias. aMCI is overrepresented in studies from memory clinics. Multivariate analyses showed that md-aMCI had a similar risk-AD relative to sd-aMCI, whereas both sd-naMCI and md-naMCI showed a lower risk-AD compared to sd-aMCI. The risk-AD was significantly associated with differences in sample sizes across studies and between groups within studies. md-aMCI had a similar risk-AD relative to sd-aMCI in studies from memory clinics and in studies in the community. Several potential sources of bias such as blindness of AD diagnosis, the MCI diagnosis approach and the reporting of demographics were associated with the risk-AD. This work provides important data for use in both clinical and research scenarios.

El presente trabajo tiene como objetivo principal identificar el impacto que existe dentro de las empresas turísticas de Bahías de Huatulco, Oaxaca, los usos y costumbres que se encuentran arraigados en los colaboradores que ahí se desempeñan. Lo anterior, definido a través de la importancia que ellos mismos le otorgan al ejercicio de estas actividades culturales derivadas de las comunidades de procedencia y al mismo tiempo reflejado en la cultura organizacional de las empresas. A partir de aquí, el artículo propone, de acuerdo a la teoría de Geert Hofstede, identificar la plataforma correspondiente a la orientación a largo plazo del destino en general y determinar cuál es la importancia que se le otorga a los usos y costumbres, de igual forma se podrá identificar si esta práctica se ve reflejada en el servicio brindado.
