Estudio limnológico de varios sistemas lóticos y lénticos aledaños a la reserva Yotoco Valle del Cauca, Colombia

Este trabajo es un estudio limnológico básico de cinco cuerpos de agua de la cuenca alta del río Cauca. Dos de ellos fueron ambientes lénticos (la laguna de Sonso y el embalse Calima) y tres fueron lóticos (el río Calima y las quebradas La Berreadera y El Boleo). Se ubican en los municipios de Buga, Yotoco y Calima en el Valle del Cauca, Colombia. Los muestreos se hicieron los días 15 y 16 de octubre de 2016. Como principal objetivo se buscó caracterizar cada uno de los lugares de muestreo en cuanto a sus variables morfológicas, fisicoquímicas y biológicas, por medio de la evaluación de distintas variables, tanto in situ como en laboratorio. Todo lo anterior permitió determinar las características generales y algunas específicas de las condiciones actuales de cada ecosistema acuático evaluado. Tales particularidades podrían ser relevantes en estudios de línea base, impacto ambiental, bioindicación y concientización ambiental

Familial hypercholesterolaemia in children and adolescents from 48 countries: a cross-sectional study

Background: Approximately 450 000 children are born with familial hypercholesterolaemia worldwide every year, yet only 2·1% of adults with familial hypercholesterolaemia were diagnosed before age 18 years via current diagnostic approaches, which are derived from observations in adults. We aimed to characterise children and adolescents with heterozygous familial hypercholesterolaemia (HeFH) and understand current approaches to the identification and management of familial hypercholesterolaemia to inform future public health strategies. Methods: For this cross-sectional study, we assessed children and adolescents younger than 18 years with a clinical or genetic diagnosis of HeFH at the time of entry into the Familial Hypercholesterolaemia Studies Collaboration (FHSC) registry between Oct 1, 2015, and Jan 31, 2021. Data in the registry were collected from 55 regional or national registries in 48 countries. Diagnoses relying on self-reported history of familial hypercholesterolaemia and suspected secondary hypercholesterolaemia were excluded from the registry; people with untreated LDL cholesterol (LDL-C) of at least 13·0 mmol/L were excluded from this study. Data were assessed overall and by WHO region, World Bank country income status, age, diagnostic criteria, and index-case status. The main outcome of this study was to assess current identification and management of children and adolescents with familial hypercholesterolaemia. Findings: Of 63 093 individuals in the FHSC registry, 11 848 (18·8%) were children or adolescents younger than 18 years with HeFH and were included in this study; 5756 (50·2%) of 11 476 included individuals were female and 5720 (49·8%) were male. Sex data were missing for 372 (3·1%) of 11 848 individuals. Median age at registry entry was 9·6 years (IQR 5·8-13·2). 10 099 (89·9%) of 11 235 included individuals had a final genetically confirmed diagnosis of familial hypercholesterolaemia and 1136 (10·1%) had a clinical diagnosis. Genetically confirmed diagnosis data or clinical diagnosis data were missing for 613 (5·2%) of 11 848 individuals. Genetic diagnosis was more common in children and adolescents from high-income countries (9427 [92·4%] of 10 202) than in children and adolescents from non-high-income countries (199 [48·0%] of 415). 3414 (31·6%) of 10 804 children or adolescents were index cases. Familial-hypercholesterolaemia-related physical signs, cardiovascular risk factors, and cardiovascular disease were uncommon, but were more common in non-high-income countries. 7557 (72·4%) of 10 428 included children or adolescents were not taking lipid-lowering medication (LLM) and had a median LDL-C of 5·00 mmol/L (IQR 4·05-6·08). Compared with genetic diagnosis, the use of unadapted clinical criteria intended for use in adults and reliant on more extreme phenotypes could result in 50-75% of children and adolescents with familial hypercholesterolaemia not being identified. Interpretation: Clinical characteristics observed in adults with familial hypercholesterolaemia are uncommon in children and adolescents with familial hypercholesterolaemia, hence detection in this age group relies on measurement of LDL-C and genetic confirmation. Where genetic testing is unavailable, increased availability and use of LDL-C measurements in the first few years of life could help reduce the current gap between prevalence and detection, enabling increased use of combination LLM to reach recommended LDL-C targets early in life

Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat

Trabajos de grado en Comunicación, resúmenes analíticos 2012-2015

Se entiende el sistema de investigación como el proceso integrado mediante el cual asignaturas y proyectos de investigación institucional posibilitan la realización de ejercicios de investigación por parte de los estudiantes del Programa de Comunicación de la Pontificia Universidad Javeriana Cali. El sistema plantea la interacción entre las asignaturas del núcleo de formación (asignaturas teóricas, talleres, y de gestión) y las asignaturas que contribuyen a la formulación, escritura y realización del trabajo de grado en la Carrera de Comunicación; tales asignaturas son: Métodos de investigación en comunicación (300CMG051), Proyecto de grado (300CMG015) y Trabajo de grado (300CMG018). Del tránsito por este sistema de investigación se espera que los estudiantes consoliden competencias para el abordaje crítico de fenómenos sociales, donde la comunicación puede ofrecer una vía interpretativa, analítica o resolutiva. Asimismo, se espera que la participación activa de los estudiantes en los proyectos institucionales de investigación permita la consecución de una comunidad académica activa, participativa y reflexiva en torno al lugar que tiene la comunicación en la comprensión de la vida social en la ciudad, la región, el país y el mundo. Este proceso es agenciado por el grupo de investigación Procesos y Medios de Comunicación de la Pontificia Universidad Javeriana Cali. A continuación se presenta una breve descripción del grupo y sus líneas

Voces de la gestión territorial. Estrategias complementarias para la conservación de la biodiversidad en Colombia

Colombia es un país con una alta riqueza biológica y cultural, tan diverso en su territorio como en las estrategias de conservación que en él se implementan. Sin embargo, muchas de estas estrategias no se han dado a conocer lo suficiente, lo que hace difícil su articulación a los procesos de gestión y ordenamiento del territorio. Existen algunos avances en su identificación como los ejercicios que se han realizado en los sistemas regionales de áreas protegidas para recopilar la información sobre estrategias complementarias de conservación en sus jurisdicciones, la articulación que realizan organizaciones privadas para identificar las iniciativas de conservación voluntaria por parte de la sociedad civil y el trabajo realizado por comunidades campesinas, indígenas y afrodescendientes para visibilizar sus áreas de conservación. Este libro, por lo tanto, tiene como objetivo visibilizar experiencias de conservación y gestión de la biodiversidad, diferentes a las áreas protegidas, teniendo en cuenta que el Convenio de Diversidad Biológica a través de la Meta Aichi 11 introduce el concepto de otras medidas efectivas de conservación basadas en áreas (OMEC) o áreas conservadas como instrumentos para lograr sistemas de conservación más completos, representativos y efectivamente gestionados (UNEP CDB, 2010). Esperamos sea un aporte para llenar un vacío de conocimiento acerca de dichas estrategias, mostrando sus principales características, los diferentes tipos de gobernanza con los que cuentan, sus mecanismos de implementación, fortalezas y debilidades, aprendizajes y cómo estos pueden ser aplicados a la gestión de la biodiversidad en el territorio.Servicios ecosistémicosGobernanzaManejo de territoriosDeforestación de bosquesPérdida y degradaciónEcosistemasComunidades localesConservación de la biodiversida
