Esta obra aborda el tema de la Bioestadística, herramienta matemática que contribuye a la explicación del proceso salud-enfermedad, cuyos fenómenos están acompañados de gran variabilidad que debe ser medida y cuantificada. Con base en su experiencia académica e investigativa, los autores buscan contribuir a desmitificar las preconcepciones que tengan los lectores sobre la Bioestadística mediante un recorrido que parte de la Estadística descriptiva - desde la necesidad de planificar las mediciones que se van adelantar para explicar el procesos salud-enfermedad - hasta la aplicación de las etapas del método estadístico: Recolección y procesamiento de datos y presentación y análisis de la información.

Cerebro, mente y conciencia es un ensayo filosófico en el que el autor, tomando como referencia las investigaciones de la neurología, interpreta las funciones mentales y la conciencia dentro de la unidad biológica del sujeto viviente, como fenómenos procedentes de la actividad automática del cerebro, de las conexiones sinápticas, de los fluidos neuroquímicos y hormonales, y de la interacción de distintos grupos de neuronas y regiones cerebrales. En el desarrollo de este libro se han trazado las bases de una teoría novedosa para explicar los procesos de la conciencia a partir de la actividad...

El hospital neogranadino del siglo XVIII y principios del XIX es una institución compleja, atravesada por múltiples tensiones e intereses. En este momento de su historia es el escenario de diversos conflictos y debates surgidos a causa de la intensificación de la política regalista, de los particulares intereses económicos y políticos de la casa de Borbón, de la discusión entre algunos sectores ilustrados sobre el sentido de la caridad practicada en el hospital, y sobre la calidad de la ayuda brindada a los pobres enfermos y a otros grupos de población que a él concurrían.

Conventional agricultural practices are often contrary to human health and environmental conservation. Use of and exposure to pesticides in agricultural communities in tropical countries is a pressing public health problem and an important facet of environmental degradation. This research project was undertaken by documenting use and exposure behaviors among agricultural communities in San Cristobal, Antioquia (Colombia). The research questions were: (1) What are the primary factors associated with the use of pesticides and do those factors differ between pesticide users and agroecological adherents? (2) How do campesino pesticide users and agroecological adherents(non-pesticide users) differ in their attitudes and beliefs with regards to pesticide use and exposure? and (3) How do these factors influence campesinos‟ behaviors associated with pesticide use and exposure? I implemented qualitative and quantitative methods in this investigation. The qualitative approach was based on community participatory ethnographic research. The latter involved participant observation, interviews, and focus groups aimed at existing pesticides users and agroecological adherents. The quantitative approach used questionnaires to derive demographic information, scale-based evaluations of attitudes and beliefs, pesticides decision making, perceived confidence, and perceived control. Findings showed that the most relevant factors related to pesticide use and their categories included: a) individual: beliefs, attitudes and knowledge; b) interpersonal: family support and cultural acceptance of pesticide use; c) economic: fear of living within financially unviable constraints, market conditions and lack of economic support from the government; d) cultural: collective acceptance or tolerance of pesticide use and exposure and onset of negative reactions when stopping pesticide use; e) political: deficient regulations for controlling pesticide use control and adequate utilization of protective equipment. Pesticide users experienced the most apprehension regarding stopping pesticide use as they often believed pesticides allow them to obtain better crop yields and, therefore, higher monetary gains. Pesticide users lacked a positive attitude toward personal protectionequipment, regardless of the risks to which they may be exposed. Pesticide training was deficient in this population showing a clear need to improve safety conditions and training to reduce occupational hazards. Future studies should explore with greater detail these attitudes and beliefs so as to promote mid- to long-term public health interventions that directly address the sense of food and income insecurity found among the population of pesticides users, which blocks their transition into a non-pesticide scenario for agricultural production. Over the short-term, public health programs should continue to educate the population of pesticide users on the immediate risks of exposure. The decision making process surrounding pesticide use in the studied population was influenced by a variety of factors. Campesinos who were prone to use pesticides for their crops often exhibited diminished degrees of knowledge about adverse effects of pesticides on human health, believed pesticides are necessary for their crops, had negative attitudes about stopping pesticide use, had a strong family influence toward the use of pesticides, experienced economic fear of stopping pesticide use, cultivated flowers as their main source of income, expressed strong social acceptance of pesticide use, experienced negative community reactions when attempting to stop pesticide use, received government subsidies for pesticide use, and had never received any training on the use of required protective equipment. Campesinos who showed more proclivities towards the use of pesticides were convinced that pesticides are necessary for their crops as they guarantee substantial yields and larger specimens of the different crop varieties. They also exhibited low perceived control, low perceived confidence, and a low perception of adverse pesticide effects on human health and the natural environment. Future studies are required to fully comprehend the unique occupational health and safety needs of these campesinos. Additionally, future studies should be aimed at designing and introducing long-term, well-structured public health interventions to increase awareness about the harmfulness of pesticides on human and environmental health so as to promote a well-established behavioral change in relation to pesticides use reduction among these communities.

Many low- and middle-income countries are experiencing a rapid increase of overweight and obesity rates. Nonetheless, there are some concerns not only about the pace of the increase in overweight and obesity, but also about inequalities in their distribution across social groups. The main aims of this thesis were to: i) examine socioeconomic differences in overweight and obesity over the last decades among women of childbearing age in low- and middle- income countries; ii) determine the contribution of reproductive variables (e.g., parity, age at first birth, breastfeeding) to socioeconomic inequalities in overweight and obesity in low- and middle-income countries; and iii) assess the impact of recently adopted poverty reduction policies, namely conditional cash transfer programs (CCT) on determinants of child health and children´s nutritional status. Overall, the prevalence of overweight and obesity among women has increased in most low- and middle-income countries across all educational groups and occupational classes in the last two decade. Nonetheless, overweight and obesity trends have rapidly increased among less educated and lower occupational classes especially in North Africa/West and Central Asia (NWA), Sub-Saharan (SS) and Latin America and the Caribbean (LAC) region. For example, women working in agriculture and production sector had an annual increase in the prevalence of overweight/obesity ranged from 2.8% in LAC region to 3.7% in the SS region. In addition, women with lower age at first birth, high parity, and shorter duration of breastfeeding had an increased odds of overweight. Nonetheless, those reproductive factors did not play a key role in explaining differences in overweight by socioeconomic status and related trends. Finally, the CCT Familias en Accion was associated with significant higher BMI z-scores among children beneficiaries of this program; BMI-for-age z-scores (β=0.14, 95%CI 0.00, 0.27, p <0.05). These results suggest that in future years, the unequal distribution of body weight between and within societies likely contributes to perpetuate poverty and poor health as in high-income countries. In addition, poverty reduction policies such as CCT programs in a middle- income country such as Colombia have not been very successful in preventing overweight and obesity. Therefore, additional efforts specifically focused on preventing an increase in inequalities in overweight and obesity are needed, targeting mothers and children from low income households.

Abstract: Dengue is a widely spread vector-borne disease. Dengue cases in the Americas have increased over the last few decades, affecting various urban spaces throughout these continents, including the tourism-oriented city of Girardot, Colombia. Interactions among mosquitoes, pathogens and humans have recently been examined using different temporal and spatial scales in attempts to determine the roles that social and ecological systems play in dengue transmission. The current work characterizes the spatial and temporal behaviours of dengue in Girardot and discusses the potential territorial dynamics related to the distribution of this disease. Methods: Based on officially reported dengue cases (2012–2015) corresponding to epidemic (2013) and inter-epidemic years (2012, 2014, 2015), space (Getis-Ord index) and space-time (Kulldorff’s scan statistics) analyses were performed. Results: Geocoded dengue cases (n = 2027) were slightly overrepresented by men (52.1%). As expected, the cases were concentrated in the 0- to 15-year-old age group according to the actual trends of Colombia. The incidence rates of dengue during the rainy and dry seasons as well as those for individual years (2012, 2013 and 2014) were significant using the global Getis-Ord index. Local clusters shifted across seasons and years; nevertheless, the incidence rates clustered towards the southwest region of the city under different residential conditions. Space-time clusters shifted from the northeast to the southwest of the city (2012–2014). These clusters represented only 4.25% of the total cases over the same period (n = 1623). A general trend was observed, in which dengue cases increased during the dry seasons, especially between December and February. Conclusions: Despite study limitations related to official dengue records and available fine-scale demographic information, the spatial analysis results were promising from a geography of health perspective. Dengue did not show linear association with poverty or with vulnerable peripheral spaces in intra-urban settings, supporting the idea that the pathogenic complex of dengue is driven by different factors. A coordinated collaboration of epidemiological, public health and social science expertise is needed to assess the effect of “place” from a relational perspective in which geography has an important role to play. Resumen: El dengue es una enfermedad trasmitida por vectores ampliamente distribuida. En las últimas décadas el dengue ha aumentado en América, afectando diferentes espacios urbanos del continente incluyendo la ciudad turística de Girardot, Colombia. La interacción entre mosquitos, patógenos y humanos se ha examinado usando diferentes escalas espaciales y temporales para determinar la función que tienen los sistemas sociales y ecológicos en la transmisión del dengue. Este trabajo caracteriza el comportamiento espacial y temporal del dengue en Girardot y discute el potencial que tienen las dinámicas territoriales en la distribución de esta enfermedad. Métodos: Se realizaron análisis espaciales (Índice Getis-Ord) y espaciotemporales (Estadística de Kulldorff) utilizando los reportes oficiales de casos de dengue (2012-2015), los cuales corresponden a periodos epidémicos (2013) e interepidémicos (2012, 2014, 2015). Resultados: Dentro de los casos georreferenciados (n = 2027) hubo una representación ligeramente mayor de hombres (52.1%). Según lo esperado, de acuerdo a las tendencias actuales en Colombia, los casos se concentraron en la población de 0 a 15 años. El índice de Getis-Ord fue significativo para las tasas de incidencia de dengue en periodo de lluvia y periodo de sequía, al igual que para los años de estudio (2012, 2013 and 2014). Se identificaron conglomerados locales en toda la ciudad, sin embargo, estos se agruparon en la parte suroeste de la ciudad en diferentes condiciones residenciales. Los conglomerados espaciotemporales se desplazaron del noreste hacia el suroeste de la ciudad (2012–2014). Estos conglomerados espaciotemporales representan solo el 4.25% del total de casos del periodo (n = 1623). Se identificó una tendencia general de aumento de casos durante la época de sequía, especialmente entre diciembre y febrero. Conclusiones: A pesar de las limitaciones relacionadas a los registros oficiales de casos de dengue y la información demográfica disponible, los resultados fueron promisorios desde la perspectiva de la geografía de la salud. El dengue no mostró una relación lineal con la pobreza o con espacios periféricos vulnerables en espacios intraurbanos. Esto apoya la idea que el complejo patogénico del dengue comprende múltiples factores. Se requiere de una colaboración coordinada entre la epidemiología, la salud pública y las ciencias sociales para evaluar el efecto que tiene el “lugar” desde una perspectiva relacional donde la geografía tiene un rol importante a desempeñar.

Este estudio plantea una nueva perspectiva en la evaluación de las afasias y, en general, de las patologías del lenguaje, una perspectiva caracterizada por la búsqueda de una lógica en la experiencia específicametne humana del decir. Dicha lógica incluye, de manera paradójica, entre sus fundamento el no decir o el decir más tarde. Inhibición y atención orientada a meta son consideradas habitualmente como efectos propios de estados conscientes, pero al menor por lo que al lenguaje se refiere dichos efectos se manifiestan también en niveles preconscientes.
