Mental health of the staff of Unit Medicine of Family Number 73 during phase III to COVID-19

El impacto de la pandemia por Covid-19 va más allá de las manifestaciones clínicas de la enfermedad, ha cambiado radicalmente y en un breve periodo de tiempo el modo de vida en el mundo entero. Según datos de la Organización Mundial de la Salud, el 25% de la población padece algún trastorno mental y el 65% no recibe atención, así mismo, en situaciones de crisis, esto aumenta exponencialmente. El objetivo de este estudio ha consistido en analizar la salud mental del personal trabajador de la Unidad de Medicina Familiar Número 73 durante la fase III de la contingencia por Covid-19. Este estudio nos demuestra que al tener una mayor información acerca de la historia natural de la enfermedad y contar con herramientas diagnóstico-terapéuticas, el personal presenta menos alteraciones en su salud mental.The impact of the Covid-19 pandemic goes beyond the clinical manifestations of the disease, it has radically changed the way of life throughout the world in a short period of time. According to data from the World Health Organization, 25% of the population suffers from some mental disorder and 65% do not receive care; likewise, in crisis situations, this increases exponentially. The objective of this study was to analyze the mental health of the working staff of Family Medicine Unit Number 73 during phase III of the Covid-19 contingency. This study shows us that by having more information about the natural history of the disease and having diagnostic-therapeutic tools, the staff has fewer alterations in their mental health

Influence of the Synthesis Method on the Preparation Composites Derived from TiO2-LDH for Phenol Photodegradation

Three different TiO2 catalysts are prepared using different methods. MgAl-CO32− layered double hydroxides (LDH) were obtained by the sol-gel method. In the preparation of the composites, the three photocatalysts were combined with LDH following different methodologies. The composites were characterized using X-ray diffraction (XRD), specific surface area (SA), atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS). The influence of the synthesis method on the preparation of the composites was evaluated by analyzing their photocatalytic activity against phenol as a model organic pollutant under UV irradiation. The photocatalytic activity of the composites improves when the chemical interaction, determined by XPS, between the TiO2 and the LDH decreases. The same happens when the ratio of the anatase-rutile phases, determined by XRD, approaches optimum (80:20%). The effect of the composite concentration in the solution (0.5–2.0 g/L) was investigated, and the light-shielding phenomenon due to high composite concentration decreases the phenol photodegradation. The reduction of photocatalytic activity in reuse cycles is due to loss and partial deactivation of the material. The elimination of phenol is attributed primarily to the photocatalytic process due to the generation of ●OH radicals and to a lesser extent the adsorption process also present in the samples

West Nile Virus Survey of Birds, Horses, and Mosquitoes of the Pacific Coast, Southern Mexico

Abstract. Serology of West Nile virus vectors and non-human reservoirs was surveyed at Acapulco, Jose Azueta, and Ometepec, three Pacific Coast localities of Guerrero State, Mexico. The objectives of this study were to use enzyme-linked immnosorbent assay (ELISA) to assess West Nile virus antibodies of bird and equine serum samples and use reverse transcription of polymerase chain reaction (RT-PCR) to detect the virus in field-collected resting mosquitoes. Forty birds trapped using mist nets yielded 10% seroprevalence. Similarly, 18.6% of 102 equine blood samples had West Nile virus. In addition, 4,854 mosquitoes were caught using motorized backpack aspirators and grouped into 116 pools. Of the 16 species and seven genera, no mosquito was positive for West Nile virus. Our study demonstrated West Nile virus seroprevalence on resident birds and equines in Guerrero State, Mexico

Advances in Science No. 01

Esta publicación tiene la decidida intención de acercar la investigación que realiza la Universidad del Rosario de Bogotá, Colombia, a un gran número de lectores para mostrarles, desde el periodismo científico, el quehacer investigativo de la institución. Queremos presentarle al mundo, tal como lo dijo hace dos siglos uno de nuestros hijos más ilustres, Francisco José de Caldas, el sentido final del ejercicio de investigar: “[...] todo para bienestar de los hombres”.It is the explicit goal of this publication is to get research carried out by the Universidad del Rosario in Bogotá, Colombia to a large number of readers, showing them, through sci-ence journalism, the daily investigative work carried out at this institution. And we want the world to see it in the spirit of the ultimate meaning of the practice of research, just as it was expressed two centuries ago by one of our most illustrious sons, Francisco José de Caldas, who underlined that it is “all for the well-being of humankind.
