    Mental Health in Chilean Higher Education Students During the COVID-19 Pandemic: A Longitudinal Study
    (2024) Garcia, Felipe E.; Andrades, Mariela; Kilmer, Ryan P.; Rodriguez, Fernando; Lucero, Cibelle; Diaz, Zamira
    Objective: The COVID-19 pandemic has required important changes in the lifestyles and quality of life of higher education students, generating emotional distress. This study sought to evaluate a predictive model of emotional distress and positive mental health through measures of posttraumatic stress symptoms (PTSS) and posttraumatic growth (PTG) in Chilean higher education students during the pandemic. Method: To this end, 502 students (67.8% female), aged 18-44 years, were surveyed at two time points during the pandemic, separated by 6 months. Potential predictors included emotional regulation strategies, perceived social support, sociodemographic characteristics, factors related to the pandemic, and students' experiences related to online classes. Results: Findings indicated that PTSS levels were generally stable across the two time points, but PTG levels increased. In addition, emotional regulation strategies (suppression, cognitive reappraisal), perceived social support, and female gender predicted both PTSS and PTG 6 months later; students' number of hours of screen time for school also influenced PTG. Conclusions: Findings enhance understanding of the processes contributing to PTSS and PTG in higher education students. The need to improve quality of life and mental health in higher education students, including individual- and institutional-level strategies, is discussed.

    Replenishment of type VII collagen and re-epithelialization of chronically ulcerated skin after intradermal administration of allogeneic mesenchymal stromal cells in two patients with recessive dystrophic epidermolysis bullosa
    (INFORMA HEALTHCARE, 2010) Conget, Paulette; Rodriguez, Fernando; Kramer, Susanne; Allers, Carolina; Simon, Valeska; Palisson, Francis; Gonzalez, Sergio; Yubero, Maria J.
    In animal models it has been shown that mesenchymal stromal cells (MSC) contribute to skin regeneration and accelerate wound healing. We evaluated whether allogeneic MSC administration resulted in an improvement in the skin of two patients with recessive dystrophic epidermolysis bullosa (RDEB; OMIM 226600). Patients had absent type VII collagen immunohistofluorescence and since birth had suffered severe blistering and wounds that heal with scarring. Vehicle or 0.5x10
