This paper seeks to analyze in an objective way the circumstances and events that contributed to the 1985 Nevado del Ruiz catastrophe, in order to provide useful guidelines for future emergencies. The paper is organized into two principal parts. In the first part, an Anatomy of the catastrophe is developed as a step-by-step chronicle of events and actions taken by individuals and organizations during the period November 1984 through November 1985. This chronicle provides the essential background for the crucial events of November 13. This year-long period is broken down further to emphasize important chapters: the gradual awareness of the awakening of the volcano; a long period of institutional skepticism reflecting an absence of credibility; the closure of the credibility gap with the September 11 phreatic eruption, followed by an intensive effort to gird for the worst; and a detailed account of the day of reckoning. The second part of the paper, Retrospection, examines the numerous complicated factors that influenced the catastrophic outcome, and attempts to cull a few "lessons from Armero" in order to avoid similar occurrences in the future. In a nutshell, the government on the whole acted responsibly but was not willing to bear the economic or political costs of early evacuation or a false alarm. Science accurately foresaw the hazards but was insufficiently precise to render reliable warning of the crucial event at the last possible minute. Catastrophe was therefore a calculated risk, and this combination - the limitations of prediction/detection, the refusal to bear a false alarm and the lack of will to act on the uncertain information available - provided its immediate and most obvious causes. But because the crucial event occurred just two days before the Armero emergency management plan was to be critically examined and improved, the numerous circumstances which delayed progress of emergency management over the previous year also may be said to have

Catastrophic volcanic collapse: relation to hydrothermal processes.

PubMed

López, D L; Williams, S N

1993-06-18

Catastrophic volcanic collapse, without precursory magmatic activity, is characteristic of many volcanic disasters. The extent and locations of hydrothermal discharges at Nevado del Ruiz volcano, Colombia, suggest that at many volcanoes collapse may result from the interactions between hydrothermal fluids and the volcanic edifice. Rock dissolution and hydrothermal mineral alteration, combined with physical triggers such as earth-quakes, can produce volcanic collapse. Hot spring water compositions, residence times, and flow paths through faults were used to model potential collapse at Ruiz. Caldera dimensions, deposits, and alteration mineral volumes are consistent with parameters observed at other volcanoes.

Aedes albopictus is the second most important dengue virus vector in the Asian southeast after Aedes aegypti. Its entrance into the Americas occurred in 1985, and laboratory studies performed show its potential as a vector in this continent as well. In Colombia, this species has been reported in Leticia (Amazonas) in 1998 and Buenaventura (Valle del Cauca) in 2001. The latest discoveries show that this mosquito continues to advance toward the country's interior. To inform that the presence of A. albopictus is documented in the city of Cali, Valle del Cauca, Colombia. Since 2002, weekly sampling has been performed using larval traps located at seventeen stations. The identification of the A. albopictus species, was carried out in the Unidad de Entomología, Laboratorio de Salud Pública Departamental. These identifications were confirmed in the Entomology Laboratory at Universidad del Valle and the National Institute of Health in Bogotá. From April to June of 2006, larvae of A. albopictus were found in six sampling stations located between northwest and northeast of Cali, one of them in the suburban area of the Yumbo city. The control of A. aegypti and A. albopictus must be integrated into a single program. The surveillance in the cities and nearest departments must be intensified with the objective of limiting the advancement of A. albopictus.

Volcano-hazards Education for Emergency Officials Through Study Trip Learning—The 2013 Colombia-USA Bi-national Exchange

A central tenant of hazard communication is that colleagues with principal responsibilities for emergency planning and response sustain a 'long-term conversation' that builds trust, and increases understanding of hazards and successful protocols. This requires well maintained partnerships among a broad spectrum of officials who are knowledgeable about volcano hazards; credible within their communities; and who have personal and professional stake in their community's safety. It can require that volcano scientists facilitate learning opportunities for partners in emergency management who have little or no familiarity with eruption response. Scientists and officials from Colombia and the Cascades region of the United States recognized that although separated by geographic and cultural distance, their communities faced similar hazards from lahars. For the purpose of sharing best practices, the 2013 Colombia-USA Bi-national Exchange was organized by the US Geological Survey (USGS) and the Washington Emergency Management Division, with support from the US Agency for International Development (USAID). Nine Colombian emergency officials and scientists visited the U.S. to observe emergency response planning and protocols and to view the scale of a potential lahar disaster at Mount Rainier. Ten U.S. delegates visited Colombia to absorb best practices developed after the catastrophic 1985 eruption and lahars at Nevado del Ruiz. They observed the devastation and spoke with survivors, first responders, and emergency managers responsible for post-disaster recovery efforts. Delegates returned to their nations energized and with improved knowledge about volcanic crises and effective mitigation and response. In the U.S., trainings, hazard signage, evacuation routes and assembly points, and community websites have gained momentum. Colombian officials gained a deeper appreciation of and a renewed commitment to response planning, education, and disaster preparedness.

Vapor Discharges On Nevado Del Ruiz During The Recent Activity: Clues On The Composition Of The Deep Hydrothermal System And Its Effects On Thermal Springs

2015-12-01

The Nevado del ruiz volcano (NdR, 5321m asl), one of the most active in Colombia, threatens about 600,000 people. The existence of an ice cap and several streams channeling in some main rivers increase the risk of lahars and mudflows in case of unrest, as occurred during the November 1985 eruption, which caused 20,000 casualties. The involvement of the local hydrothermal system has also produced in the past phreatic and phreatomagmatic activity, as in 1985 and 1989. After more than 7 years of relative stability, since 2010, the still ongoing phase of unrest has produced two small eruption in 2012, and still maintains in high levels of seismicity and SO2 degassing. In October 2013, a sampling campaign has been performed on thermal springs and streamwater, located at 2600-5000 m asl, analyzed for water chemistry and stable isotopes. By applying a model of steam-heating, based on mass and enthalpy balances, we have estimated the mass rate of steam discharging in the different steam-heated springs. The composition of the hottest thermal spring (Botero Londoño) is probably representative of a marginal part of the hydrothermal system, having a temperature of 250°C and low salinity (Cl ~1500 mg/l), which suggest a chiefly meteoric origin, as also confirmed by the isotope composition retrieved for the hydrothermal water. The vapour discharged at the steam vent "Nereidas" (3600 m asl) is hypothesised to be separated from a high-temperature hyrothermal system. Based on its composition and on literature data on fluid inclusions, we have retrieved the P-T-X conditions of the deep hydrothermal system, as well as its pH and fO2. The vapour feeding Nereidas would separate from a byphasic hydrothermal system characterised by the follow parameters: t= 315°C, P=19 MPa, NaCl= 15 %, CO2 = 9%, and similar proportion between liquid and vapour. Considering also the equilibria involving S-bearing gases and HCl, we obtain pH=2, fO2 fixed by FeO-Fe2O3 buffer, and [Cl]=12000 mg/l. Changes

In this paper is presented a model that analyses the options to provide energy to an interconnected house in Lagos del Cacique, Bucaramanga, Colombia. Three power supplies were considered: photovoltaic, 1 kW wind turbine, and a 2.6kW gasoline generator, as well as a battery for energy storage. The variables considered for the sensitivity analysis correspond to the price of gasoline and the variation in loads. The simulation results suggest an optimal configuration of microgrids in generator-photovoltaic panel-battery. Sensitivity variables were specified in order to evaluate the effect of uncertainty. The simulation was done through the Homer software and the results of the combinations of sources are suggestions of the same.

Earth Observations taken by the Expedition 23 Crew

2010-04-23

ISS023-E-027737 (23 April 2010) --- Nevado del Ruiz volcano in Colombia is featured in this image photographed by an Expedition 23 crew member on the International Space Station. The large Nevado del Ruiz volcano (center) is located approximately 140 kilometers to the northwest of the capital city of Bogota and covers an area of over 200 square kilometers. Nevado del Ruiz is a stratovolcano – a type of volcano built from successive layers of lava, ash, and pyroclastic flow deposits – formed by magma generated above the boundary between the subducting Nazca and overriding South American tectonic plates. The historical record of eruptions extends back to 1570, but the most damaging eruption in recent times took place in 1985. On Nov. 13, 1985, an explosive eruption at the Arenas Crater (center) melted ice and snow at the summit of the volcano. This lead to the formation of mudflows (or lahars) that swept tens of kilometers down river valleys along the volcano’s flanks, resulting in the deaths of at least 23,000 people. Most of the fatalities occurred in the town of Armero which was completely inundated by lahars. Eruptive activity at Nevado del Ruiz may have occurred in 1994, but this is not confirmed. The volcano’s summit and upper flanks are covered by several glaciers that appear as a white mass surrounding the one-kilometer-wide Arenas Crater; meltwater from these glaciers has incised the gray to tan ash and pyroclastic flow deposits mantling the lower slopes. A well-defined lava flow is visible at lower right. This photograph was taken at approximately 7:45 a.m. local time when the sun was still fairly low above the horizon, leading to shadowing to the west of topographic high points.

Coping with volcanic hazards; a global perspective

Compared to some other natural hazards-such as floods, storms, earthquakes, landslides- volcanic hazards strike infrequently. However, in populated areas , even very small eruptions can wreak havoc and cause widespread devastation. For example, the 13 November 1985 eruption of Nevado del Ruiz in Colombia ejected only about 3 percent of the volume of ash produced during the 18 May 1980 eruption of Mount St. Helens. Yet, the mudflows triggered by this tiny eruption killed more than 25,000 people.

Time Average Field and Secular Variations of Pleistocene to Recent Lava Flows From the Ruiz-Tolima Volcanic Complex (Colombia)

2009-05-01

Thirty three Pleistocene to recent lava flows from the Ruiz-Tolima Volcanic Complex (Colombian Andes) have been sampled for time average field (TAF) and paleosecular variation studies. A total of 10 cores were drilled per flow (site) and stepwise AF demagnetization has been carried out. After principal component analysis and mean-site direction calculations, 29 sites (25 and 4 with normal and reverse polarity, respectively), with α95 < 5.5° were selected for further calculations. The overall mean direction among the sites (D = 1.8°, I = 6.3°, α95 = 5.6°) closely fits (at the 95% confidence level) the expected paleomagnetic direction (at the area of study) of a geomagnetic field composed primarily by a geocentric axial dipole with 5% axial quadrupole component (I = 5.72°), but also coincides with a simple GAD model. VGP scatter (13°) is similar to that expected from Model G (12.8°).

Centrolene notostictum Ruiz-Carranza Lynch,1991 is a glassfrog known from the Cordillera Oriental of Colombia-in the Departments of Boyacá, Cundinamarca, Norte de Santander and Santander (Frost 2017)-and the Venezuelan versant of the Sierra de Perijá (Rojas et al. 2012) from 1600 to 2440 masl. Although males have been found calling on the upper surface of the leaves of ferns and Heliconeaceae on the margins of a small fast-flowing stream (Rojas et al. 2012), no quantitative description of the advertisement call of C. notostictum is currently available. During fieldwork in the Galilea Natural Forest (on the western slope of Cordillera Oriental in the municipality of Villarrica, department of Tolima, Colombia) in 2016 and 2017, we found three vocalizing males of C. notostictum. Herein, we report the first geographic record of this species for the department of Tolima and describe its previously unknown advertisement call.

This study was conducted to determine Anopheles species composition and their natural infectivity by human Plasmodium in 2 localities with the highest malaria transmission in San Jose del Guaviare, Guaviare, Colombia. A total of 1,009 Anopheles mosquitoes were collected using human landing catches during 8 months in 2010. Anopheles darlingi was the most abundant (83.2%) followed by An. albitarsis s.l. (8.6%), Anopheles braziliensis (3.8%), An. oswaldoi s.l. (1%), and An. rangeli (0.3%). Anopheles darlingi showed the highest human biting rate, and it was found naturally infected with Plasmodium vivax VK210 (0.119%) using enzyme-linked immunosorbent assays. All species were collected biting both indoors and outdoors. Anopheles darlingi showed biting activity overnight with an indoor peak between 1200–0100 h. Therefore, we recommend that malaria prevention strategies focus on 1) insecticide-treated nets to reduce human–vector contact when people are most exposed and unprotected; 2) accurate diagnoses; 3) adequate treatment for patients; 4) more timely epidemiological notification; and 5) improved entomological surveillance.

Petrographic and Geochemical Characterization of the Cambumbia STOCK in Andean Central Cordillera, Colombia

NASA Astrophysics Data System (ADS)

Rojas Lequerica, S.; Jaramillo Mejía, J.; Concha Perdomo, A.

2012-12-01

The Cambumbia Stock is located on the western flank of the Central Cordillera of the northern Andes. The goals of this study were to petrographic and geochemically characterize the Cambumbia igneous body and to establish its petrogenetic history. 41 samples were collected, 28 for petrographic analysis and 14 for elementary chemical determination by ICP-MS. Petrographically the samples were classified as hornblende and pyroxene-gabbros varying to diorites, gabbronorites and tonalites, the rock texture varies from medium to coarse granular grain, with local microporfiritic texture. It was concluded from the major elements analysis that the samples correspond to the sub-alkaline series with low K content, mainly in the calc-alkaline series, within the gabbros and diorites fields. By using the SiO2 vs TiO2 (Jaramillo, 1980), Th/Yb vs Ta/Yb (Pearce, 1984) (Fig. 1) and Zr/117-Th-Nb/16 (Wood, 1979) diagrams it was determined that these rocks were generated in two geotectonic environments: one type MOR (extension) and other island arc (subduction, compression). Petrographic and geochemical comparisons between the rocks of Cambumbia Stock and Diorite and Gabbro El Pueblito (Giraldo, 2009) (located about 25 km to the north-west) may postulate a possible genetic link between them. Recently, a U/Pb age was obtained by the Universidad de Caldas in zircon in 2009 (not published data), yielded an age of 233.41 ± 3.4 Ma (Middle Triassic). This age is consistent with the global event of the extension and fragmentation of Pangea supercontinent. In addition, the mantle nature of the source and the petrogenetic evolution of the magmatic system were established.

Towards understanding the puzzling lack of acid geothermal springs in Tibet (China): Insight from a comparison with Yellowstone (USA) and some active volcanic hydrothermal systems

USGS Publications Warehouse

Nordstrom, D. Kirk; Guo, Qinghai; McCleskey, R. Blaine

2014-01-01

Explanations for the lack of acid geothermal springs in Tibet are inferred from a comprehensive hydrochemical comparison of Tibetan geothermal waters with those discharged from Yellowstone (USA) and two active volcanic areas, Nevado del Ruiz (Colombia) and Miravalles (Costa Rica) where acid springs are widely distributed and diversified in terms of geochemical characteristic and origin. For the hydrothermal areas investigated in this study, there appears to be a relationship between the depths of magma chambers and the occurrence of acid, chloride-rich springs formed via direct magmatic fluid absorption. Nevado del Ruiz and Miravalles with magma at or very close to the surface (less than 1–2 km) exhibit very acidic waters containing HCl and H2SO4. In contrast, the Tibetan hydrothermal systems, represented by Yangbajain, usually have fairly deep-seated magma chambers so that the released acid fluids are much more likely to be fully neutralized during transport to the surface. The absence of steam-heated acid waters in Tibet, however, may be primarily due to the lack of a confining layer (like young impermeable lavas at Yellowstone) to separate geothermal steam from underlying neutral chloride waters and the possible scenario that the deep geothermal fluids below Tibet carry less H2S than those below Yellowstone.

Classification and Space-Time Analysis of Precipitation Events in Manizales, Caldas, Colombia.

Suarez Hincapie, J. N.; Vélez, J.; Romo Melo, L.; Chang, P.

2015-12-01

Manizales is a mid-mountain Andean city located near the Nevado del Ruiz volcano in west-central Colombia, this location exposes it to earthquakes, floods, landslides and volcanic eruptions. It is located in the intertropical convergence zone (ITCZ) and presents a climate with a bimodal rainfall regime (Cortés, 2010). Its mean annual rainfall is 2000 mm, one may observe precipitation 70% of the days over a year. This rain which favors the formation of large masses of clouds and the presence of macroclimatic phenomenon as "El Niño South Oscillation", has historically caused great impacts in the region (Vélez et al, 2012). For example the geographical location coupled with rain events results in a high risk of landslides in the city. Manizales has a hydrometeorological network of 40 stations that measure and transmit data of up to eight climate variables. Some of these stations keep 10 years of historical data. However, until now this information has not been used for space-time classification of precipitation events, nor has the meteorological variables that influence them been thoroughly researched. The purpose of this study was to classify historical events of rain in an urban area of Manizales and investigate patterns of atmospheric behavior that influence or trigger such events. Classification of events was performed by calculating the "n" index of the heavy rainfall, describing the behavior of precipitation as a function of time throughout the event (Monjo, 2009). The analysis of meteorological variables was performed using statistical quantification over variable time periods before each event. The proposed classification allowed for an analysis of the evolution of rainfall events. Specially, it helped to look for the influence of different meteorological variables triggering rainfall events in hazardous areas as the city of Manizales.

Given the severity of the disease at national and global levels, new predictive methodologies need to be generated to facilitate decision-making in public health.  To characterize cases of dengue reported from 2009 to 2013 in Valle del Cauca department, Colombia, and to establish a methodology to develop endemic channels that can be applied to this event.  This was a retrospective descriptive study. Notification forms were used as a secondary database to characterize dengue cases from 2009 to 2013. Two endemic channels were developed, one using running means and the other through exponential smoothing.  Dengue in the department of Valle del Cauca showed a positive tendency, indicating that the number of cases had increased in the last five years. An important variation was observed that could be explained by a three-year cycle beginning in the first epidemiological period of the year.  The development of the dengue endemic channel for Valle del Cauca illustrates the importance of applying these monitoring methodologies to events of public health interest. As can be seen from the results, there were some years in which the number of cases was very low and others in which the epidemic reached very high levels.

Andean volcanism occurs within the Andean Volcanic Arc (AVA), which is the product of subduction of the Nazca Plate and Antarctica Plates beneath the South America Plate. The AVA is Earth's longest but discontinuous continental-margin volcanic arc, which consists of four distinct segments: Northern Volcanic Zone, Central Volcanic Zone, Southern Volcanic Zone, and Austral Volcanic Zone. These segments are separated by volcanically inactive gaps that are inferred to indicate regions where the dips of the subducting plates are too shallow to favor the magma generation needed to sustain volcanism. The Andes host more volcanoes that have been active during the Holocene (past 10 000 years) than any other volcanic region in the world, as well as giant caldera systems that have produced 6 of the 47 largest explosive eruptions (so-called "super eruptions") recognized worldwide that have occurred from the Ordovician to the Pleistocene. The Andean region's most powerful historical explosive eruption occurred in 1600 at Huaynaputina Volcano (Peru). The impacts of this event, whose eruptive volume exceeded 11 km3, were widespread, with distal ashfall reported at distances >1000 km away. Despite the huge size of the Huaynaputina eruption, human fatalities from hazardous processes (pyroclastic flows, ashfalls, volcanogenic earthquakes, and lahars) were comparatively small owing to the low population density at the time. In contrast, lahars generated by a much smaller eruption (<0.05 km3) in 1985 of Nevado del Ruiz (Colombia) killed about 25 000 people - the worst volcanic disaster in the Andean region as well as the second worst in the world in the 20th century. The Ruiz tragedy has been attributed largely to ineffective communications of hazards information and indecisiveness by government officials, rather than any major deficiencies in scientific data.

Gold-mining may play an important role in the maintenance of malaria worldwide. Gold-mining, mostly illegal, has significantly expanded in Colombia during the last decade in areas with limited health care and disease prevention. We report a descriptive study that was carried out to determine the malaria prevalence in gold-mining areas of Colombia, using data from the public health surveillance system (National Health Institute) during the period 2010-2013. Gold-mining was more prevalent in the departments of Antioquia, Córdoba, Bolívar, Chocó, Nariño, Cauca, and Valle, which contributed 89.3% (270,753 cases) of the national malaria incidence from 2010-2013 and 31.6% of malaria cases were from mining areas. Mining regions, such as El Bagre, Zaragoza, and Segovia, in Antioquia, Puerto Libertador and Montelíbano, in Córdoba, and Buenaventura, in Valle del Cauca, were the most endemic areas. The annual parasite index (API) correlated with gold production (R2 0.82, p < 0.0001); for every 100 kg of gold produced, the API increased by 0.54 cases per 1,000 inhabitants. Lack of malaria control activities, together with high migration and proliferation of mosquito breeding sites, contribute to malaria in gold-mining regions. Specific control activities must be introduced to control this significant source of malaria in Colombia. PMID:26814645

The expansion of the agricultural frontier in Colombia has exerted significant pressure on its aquatic ecosystems during the last few decades. In order to determine the impacts of different agricultural land uses on the biotic and abiotic characteristics of first and second order streams of La Vieja river watershed, we evaluated 21 streams located between 1,060 and 1,534 m asl in the municipalities of Alcalá, Ulloa, and Cartago (Valle del Cauca, Colombia). Seven streams were protected by native vegetation buffers, eight had influence of coffee and plantain crops, and six were influenced by cattle ranching. Habitat conditions, channel dimensions, water quality, and aquatic macroinvertebrates were studied in each stream. Streams draining cattle ranching areas had significantly higher dissolved solids, higher phosphorus, higher alkalinity, higher conductivity, and lower dissolved oxygen than those covered by cropland and forests. Coarse substrates and diversity of flow regimes were significantly higher in cropland and protected streams when compared to streams affected by cattle ranching, whereas the percent of silt and slow currents was significantly higher in the latter. A total of 26,777 macroinvertebrates belonging to 17 orders, 72 families and 95 genera were collected. The most abundant groups were Diptera 62.8%, (Chironomidae 49.6%, Ceratopogonidae 6.7%), Mollusca 18.8% (Hydrobiidae 7.2%, Sphaeriidae 9.6%) and Trichoptera 5.7% (Hydropsychidae 3.7%). The Ephemeroptera, Trichoptera, and Plecoptera orders, known for their low tolerance to habitat perturbation, had high abundance in cropland and forested streams, whereas Diptera and Mollusca were more abundant in those impacted by cattle ranching. Results indicate that streams draining forests and croplands have better physical and biological conditions than those draining pastures, and highlight the need to implement protective measures to restore the latter.

RESUMEN Introducción Las infecciones del tracto urinario (ITU) son frecuentes en la comunidad. Sin embargo, la información de aislamientos resistentes en este contexto es limitada en Latinoamérica. Este estudio tiene como objetivo determinar la prevalencia y los factores de riesgo asociados con ITU de inicio en la comunidad (ITU-IC) causadas por Escherichia coli productor de betalactamasas de espectro extendido (BLEE) en Colombia. Materiales y métodos Entre agosto y diciembre de 2011 se realizó un estudio de casos y controles en 3 instituciones de salud de tercer nivel en Colombia. Se invitó a participar a todos los pacientes admitidos a urgencias con diagnóstico probable de ITU-IC, y se les pidió una muestra de orina. En los aislamien-tos de E. coli se realizaron pruebas confirmatorias para BLEE, susceptibilidad antibiótica, caracterización molecular (PCR en tiempo real para genes bla, repetitive element palindromic PCR [rep-PCR], multilocus sequence typing [MLST] y factores de virulencia por PCR). Se obtuvo información clínica y epidemiológica, y posteriormente se realizó el análisis estadístico. Resultados De los 2.124 pacientes seleccionados, 629 tuvieron un urocultivo positivo, en 431 de estos se aisló E. coli, 54 fueron positivos para BLEE y 29 correspondieron a CTX-M-15. La mayoría de los aislamientos de E. coli productor de BLEE fueron sensibles a ertapenem, fosfomicina y amikacina. La ITU complicada se asoció fuertemente con infecciones por E. coli productor de BLEE (OR = 3,89; IC 95%: 1,10–13,89; p = 0,03). E. coli productor de CTX-M-15 mostró 10 electroferotipos diferentes; de estos, el 65% correspondieron al ST131. La mayoría de estos aislamientos tuvieron 8 de los 9 factores de virulencia analizados. Discusión E. coli portador del gen blaCTX-M-15 asociado al ST131 sigue siendo frecuente en Colombia. La presencia de ITU-IC complicada aumenta el riesgo de tener E. coli productor de BLEE, lo cual debe tenerse en cuenta para ofrecer

The complete genome sequence of a bipartite begomovirus (genus Begomovirus, family Geminiviridae) infecting yellow passion fruit (Passiflora edulis) in the state of Valle del Cauca (Colombia) has been determined. The complete DNA-A and DNA-B components were determined to be 2600 and 2572 nt in length, respectively. The DNA-A showed the highest nucleotide sequence identity (87.2 %) to bean dwarf mosaic virus (M88179), a begomovirus found in common bean crops in Colombia, and only 77.4 % identity to passion fruit severe leaf distortion virus (FJ972767), a begomovirus identified infecting passion fruit in Brazil. Based on its sequence identity to all other begomoviruses known to date and in accordance with the ICTV species demarcation criterion for the genus Begomovirus (≥91 % sequence identity for the complete DNA-A), the name passion fruit leaf distortion virus is proposed for this new begomovirus. To our knowledge, this is the first report of a bipartite begomovirus affecting passion fruit in Colombia and the second report of a geminivirus affecting this crop worldwide.

Site testing in Colombia : Identification of the least-worst places for optical telescopes

Pinzón, G.

2017-07-01

With the aim of identifying a set of least-worst sites for astronomical observations in Colombia we used a novel algorithm for the computation of the number of clear nights over an extended region covering Colombia and the western part of Venezuela. This algorithm compares the brightness temperatures of five years of GOES images with reference temperature values obtained from long-term records of monthly temperatures at ground and at heights of 8, 9 and 10 kilometers. Our predictions were validated with cloud cover information from the log-books of the Observatorio Nacional de Llano del Hato in Venezuela. Short and sporadic expeditions to four of those sites were also done from 2013 to 2015 in order to conduct measurements in-situ of temperature and humidity along the night, seeing, sky brightness and atmospheric extinction using basic instrumentation. The final conclusions have been derived solely on the basis of the actually visited sites. It was found that at Cañón del río Nevado the Seeing during the nights was more stable with rms=0.59'' and then a suitable and extended region (of almost 30 km) for the location of optical telescopes aimed to enhance astronomy research and outreach in the country.

As part of an institutional program sponsored by the Centre for Teaching Excellence at the Universidad del Norte, Barranquilla, Colombia, we developed an educational research study on two sessions of human anatomy in which we combined team-based learning (TBL) and the use of iPads. Study data included the TBL, assessments applied during the course, student's grades on mid-term examinations and students' perceptions of their experiences. Students reported a positive attitude toward the use of the TBL sessions, and the results showed a significant improvement in their learning between the first and second sessions. Significantly positive correlations (P < 0.05) were obtained between (a) the individual students' readiness test performance 1 and mid-term examination 1, (b) the individual readiness test performances from Session 1 to Session 2, and (c) the group readiness test performances from the first and second sessions. These results point to positive learning experiences for these students. Analyses of the students' reflections on their activities also pointed toward future challenges. © 2014 American Association of Anatomists.

Volcanic hazards and their mitigation: progress and problems

Tilling, R.I.

1989-01-01

A review of hazards mitigation approaches and techniques indicates that significant advances have been made in hazards assessment, volcano monioring, and eruption forecasting. For example, the remarkable accuracy of the predictions of dome-building events at Mount St. Helens since June 1980 is unprecedented. Yet a predictive capability for more voluminous and explosive eruptions still has not been achieved. Studies of magma-induced seismicity and ground deformation continue to provide the most systematic and reliable data for early detection of precursors to eruptions and shallow intrusions. In addition, some other geophysical monitoring techniques and geochemical methods have been refined and are being more widely applied and tested. Comparison of the four major volcanic disasters of the 1980s (Mount St. Helens, U.S.A. (1980), El Chichon, Mexico (1982); Galunggung, Indonesia (1982); and Nevado del Ruiz, Colombia (1985)) illustrates the importance of predisaster geoscience studies, volcanic hazards assessments, volcano monitoring, contingency planning, and effective communications between scientists and authorities. -from Author

Campomanesia lineatifolia Ruiz and Pav. (Myrtaceae) is a native edible species found in the Amazon Rainforest, commonly known as gabiroba. In Brazil, Campomanesia species are frequently used in traditional medicine for gastrointestinal disorders. The present study performed phytochemical analyses and determined both the in vitro antioxidant activity of the ethanolic extract of Campomanesia lineatifolia leaves (EEC) as well as its ethyl acetate fraction (EAFC). In this analysis, quercetin was used as a positive control. Gastroprotective activity was also investigated at different oral doses in two experimental models in rats - gastric lesion induced by ethanol and gastric lesion induced by indomethacin. In this analysis, cimetidine and sucralfate were used as positive controls. The area of gastric lesion underwent macroscopic and histomorphometric evaluations, while the mucus content was estimated by applying the periodic acid-Schiff stain. Oral acute toxicity was also assessed. Phytochemical studies revealed the presence of flavonoids and tannins. Catechin and quercitrin were isolated by bioguided chromatographic fractionation of EAFC. EEC and EAFC presented in vitro antioxidant activity. The oral administration of EEC and EAFC at doses 100-400 mg/kg (ethanol model) and at doses of 400-1200 mg/kg (indomethacin model) proved to be effective in preventing gastric ulcerations in rats. Pretreatment with EAFC (400mg/kg) significantly increased the gastric mucus content in the ethanol model. No animals died during the acute oral toxicology test. Results confirm the Brazilian ethnopharmacological use of Campomanesia lineatifolia as a gastroprotective agent and indicate that the anti-ulcer effect is most likely mediated by scavenging free radicals due to the polyphenol content and, at least in part, by increasing the mucus secretion and the mucosal defense. In addition, EEC and EAFC were found to be safe when applied to a 2000 mg/kg single oral dose. Copyright © 2011

This article describes Colombia's development of formal dentistry, its dental school system, curriculum, and dental licensure, and current issues in oral health care. In 1969, there were only 4 dental schools in Colombia; at this writing there are 21. Five dental schools are public and the other 16 are private. Nearly all classes are conducted in Spanish. Undergraduate pre-dental coursework is not a prerequisite for dental school in Colombia. To obtain licensure, Colombian dental students must complete 5 years of study in dental school, earn a diploma, and work for the government for 1 year. There are approximately 41,400 dentists in Colombia, and the number is increasing quickly. However, the unemployment rate among dentists is very high, even though graduation from dental school is extremely difficult. Although the 1,100:1 ratio of citizens to dentists is considered satisfactory, access to dental care is limited due to the high rate of poverty. PMID:20339245

This commentary aims to delineate the distinguishing features of conflict-induced internal displacement in the nation of Colombia, South America. Even as Colombia is currently implementing a spectrum of legal, social, economic, and health programs for “victims of armed conflict,” with particular focus on internally displaced persons (IDPs), the dynamics of forced migration on a mass scale within this country are little known beyond national borders.   The authors of this commentary are embarking on a global mental health research program in Bogota, Colombia to define best practices for reaching the displaced population and implementing sustainable, evidence-based screening and intervention for common mental disorders. Presenting the defining characteristics of internal displacement in Colombia provides the context for our work and, more importantly, conveys the compelling and complex nature of this humanitarian crisis. We attempt to demonstrate Colombia’s unique position within the global patterning of internal displacement. PMID:28228997

Interactions between frugivorous bats (Chiroptera: Phyllostomidae) and Piper tuberculatum (Piperaceae) in a tropical dry forest in Valle del Cauca, Colombia.

In any ecosystem, fruits are resources that vary in time and space as well as in nutritional content. Coexistence of species from a trophic guild depends on the division and use of resources. Therefore, the organisms that depend on them as a food source, tend to show a certain degree of specialization. This way, understanding the factors that influence the dynamics of seed dispersal is important for the regeneration and conservation of tropical ecosystems. Our aim was to determine variation in consumption of Piper tuberculatum by fruit bat assemblages in the village of Robles (Jamundí, Valle del Cauca, Colombia). P. tuberculatum is a resource used not only by wildlife but also by people in the village of Robles. Bats were captured in mist nets between June and November 2014, their feces were collected, and the length of the forearm, wing area, leg length and mass were recorded. At the Universidad del Valle seed laboratory, fecal samples were washed, and their content determined. Of the 14 species captured, Sturnira lilium, Carollia brevicauda, Carollia perspicillata and Artibeus lituratus showed signs of having consumed P. tuberculatum. Sturnira lilium was the main consumer of P. tuberculatum fruits, with the greatest number of consumption events of fruit from this plant species, whereas the other bats showed more diversified consumption events. The greatest niche overlap was recorded between C. brevicauda and C. perspicillata, species that showed similar sizes (i.e., wing area and forearm length) followed by S. lilium and C. perspicillata. In contrast, A. lituratus showed the least niche overlap with the other three fruit bats captured. In conclusion, Sturnira lilium showed an interaction Sturnira-Piper, which is the result of low Solanum availability, and this bat species was the largest consumer of P. tuberculatum in the region.

• Background and Aims The labellar papillae and trichomes of Maxillaria Ruiz & Pav. show great diversity. Although papillae also occur upon other parts of the flower (e.g. column and anther cap), these have not yet been studied. Labellar trichomes of Maxillaria are useful in taxonomy, but hitherto the taxonomic value of floral papillae has not been assessed. The aim of this paper is to describe the range of floral papillae found in Maxillaria and to determine whether papillae are useful as taxonomic characters. • Methods Light microscopy, histochemistry, low‐vacuum scanning and transmission electron microscopy. • Key Results A total of 75 taxa were studied. Conical papillae with rounded or pointed tips were the most common. The column and anther cap usually bear conical, obpyriform or villiform papillae, whereas those around the stigmatic surface and at the base of the anther are often larger and swollen. Labellar papillae show greater diversity, and may be conical, obpyriform, villiform, fusiform or clavate. Papillae may also occur on multiseriate trichomes that perhaps function as pseudostamens. Labellar papillae contain protein but most lack lipid. The occurrence of starch, however, is more variable. Many papillae contain pigment or act as osmophores, thereby attracting insects. Rewards such as nectar or a protein‐rich, wax‐like, lipoidal substance may be secreted by papillae onto the labellar surface. Some papillae may have a protective role in preventing desiccation. Species of diverse vegetative morphology may have identical floral papillae, whereas others of similar vegetative morphology may not. • Conclusions Generally, floral papillae in Maxillaria have little taxonomic value. Nevertheless, the absence of papillae from members of the M. cucullata alliance, the occurrence of clavate papillae with distended apices in the M. rufescens alliance and the presence of papillose trichomes in some species may yet prove to be useful.

Las medianas de las tasas de incidencia fueron 1.371 y 188 por 100.00 habitantes para malaria y dengue, respectivamente. Además, los casos de chikungunya fueron 774.831 desde su introducción en el 2014 y, los de Zika, 117.674 desde su aparición en 2015. En las zonas rurales predominaron las enfermedades parasitarias transmitidas por vectores como la malaria, las leishmaniasis y la enfermedad de Chagas. A nivel urbano, predominaron el dengue, el chikungunya y el Zika.Conclusiones. La transmisión en Colombia de estas enfermedades es persistente en las zonas urbanas y en las rurales, y de tipo endemoepidémico en los casos de malaria, dengue, leishmaniasis y enfermedad de Chagas. Dicha transmisión se ha dado de manera focalizada y con patrones variables de intensidad. Asimismo, se mantienen las condiciones que han favorecido la transmisión emergente de nuevas arbovirosis.

Internal displacement in Colombia: Fifteen distinguishing features.

This commentary aims to delineate the distinguishing features of conflict-induced internal displacement in the nation of Colombia, South America. Even as Colombia is currently implementing a spectrum of legal, social, economic, and health programs for "victims of armed conflict," with particular focus on internally displaced persons (IDPs), the dynamics of forced migration on a mass scale within this country are little known beyond national borders.   The authors of this commentary are embarking on a global mental health research program in Bogota, Colombia to define best practices for reaching the displaced population and implementing sustainable, evidence-based screening and intervention for common mental disorders. Presenting the defining characteristics of internal displacement in Colombia provides the context for our work and, more importantly, conveys the compelling and complex nature of this humanitarian crisis. We attempt to demonstrate Colombia's unique position within the global patterning of internal displacement.

Utilizing NASA EOS Data for Fire Management in el Departmento del Valle del Cauco, Colombia

In the last few years, fire incidence in Colombian wild areas has increased, damaging pristine forests into savannas and sterile lands. Fire poses a significant threat to biodiversity, rural communities and established infrastructure. These events issue an urgent need to address this problem. NASA Earth Observing System (EOS) can play a significant role in the monitoring fires and natural disasters. SERVIR, the Regional Visualization and Monitoring Network, constitutes a platform for the observation, forecasting and modeling of environmental processes in Central America. A project called "The GIS for fire management in Guatemala (SIGMA-I)" has been already conducted to address the same problem in another Latin American country, Guatemala. SIGMA-I was developed by the Inter-agency work among the National protected areas council (CONAP), National Forestry Institution (INAB), the National Coordinator for Disaster Reduction / National Forest Fire Prevention and Control System (CONRED/SIPECIF), and the Ministry of the Environment and National Resources (MARN) in Guatemala under the guidance and assistance of SERVIR. With SIGMA-I as an example, we proposed to conduct a similar project for the country of Colombia. First, a pilot study in the area of the watershed of the Cali River, Colombia was conducted to ensure that the data was available and that the maps and models were accurate. The proposed study will investigate the technical resources required: 1.) A fire map with a compilation of ignition data (hot spots) utilizing Fire Information for Resource Management System (FIRMS) derived from MODIS (Moderate Resolution Imaging Spectroradiometer) products MOD14 and MYD14 2.) A map of fire scars derived from medium resolution satellite data (ASTER) during the period 2003-2011 for the entire country, and a map of fire scar recurrence and statistics derived from the datasets produced. 3.) A pattern analysis and ignition cause model derived from a matrix of variables

Mental health law in Colombia has evolved over the past 50 years, in concert with worldwide recognition and prioritisation of mental healthcare. Laws and policies have become increasingly sophisticated to accommodate the ongoing transformations throughout Colombia’s healthcare system and improvements in mental health screening, treatment and supportive care. Mental health law and policy development have been informed by epidemiological data on patterns of mental disorders in Colombia. Colombia is distinguished by the fact that its mental health laws and policies have been formulated during a 60-year period of continuous armed conflict. The mental health of Colombian citizens has been affected by population-wide exposure to violence and, accordingly, the mental health laws that have been enacted reflect this feature of the Colombian experience.

Gómez-Duarte, Oscar G.

2014-01-01

Resumen Las cepas de E. coli patógenas intestinales son causas importantes de la enfermedad diarreica aguda (EDA) en niños menores de 5 años en América Latina, África y Asia y están asociadas a alta mortalidad en niños en las comunidades más pobres de África y el Sudeste Asiático. Estudios sobre el papel de las E. coli patógenas intestinales en la EDA infantil en Colombia y otros países de América Latina son limitados debido a la carencia de ensayos para detección de estos patógenos en los laboratorios clínicos de centros de salud. Estudios recientes han reportado la detección de E. coli patógenas intestinales en Colombia, siendo la E. coli enterotoxigénica la cepa más frecuentemente asociada a diarrea en niños menores de 5 años. Otros patógenos detectados en estos pacientes incluyen las E. coli enteroagregativa, enteropatógena, productora de toxina Shiga, y de adherencia difusa. Con base en estudios que reportan la presencia de E. coli productora de toxina Shiga y E. coli enteroagregativa en carnes y vegetales en supermercados, se cree que productos alimentarios contaminados contribuyen a la transmisión de estos patógenos y a la infección del huésped susceptible. Más estudios son necesarios para evaluar los mecanismos de transmisión, el impacto en la epidemiologia de la EDA, y las pautas de manejo y prevención de estos patógenos que afectan la población pediátrica en Colombia.

A hallmark of Colombia is population-wide exposure to violence. To understand the realities of mental health in Colombia requires attention to the historical context of 60 years of unrelenting armed conflict overlaid upon high rates of homicide, gang activity and prevalent gender-based and intra-familial violence. The number of patients affected by trauma is extremely large, and the population burden of alcohol misuse and illicit drug use is significant. These patterns have brought the subspecialties of trauma and addiction psychiatry to the forefront, and highlight the need for novel treatments that integrate psychotherapeutic and psychopharmacological modalities.

Located in the Central Cordillera (Colombian Andes), Nevado del Ruiz is a volcanic complex, topped by glaciers, rising 5,321 m above sea level. A relatively small explosive eruption from Ruiz's summit crater on November 13, 1985, generated an eruption column and sent a series of pyroclastic flows and surges across the volcano's ice-covered summit. Pumice and meltwater produced by the hot pyroclastic flows and surges swept into gullies and channels on the slopes of Ruiz as a series of lahars. Within two hours of the beginning of the eruption, lahars had traveled 100 km and left behind a wake of destruction: more than 25,000 people were killed (23,000 in the town of Armero and 2,000 in the town of Chinchiná), about 5,000 injured, and more than 5,000 homes destroyed along the Chinchiná, Gualí, and Lagunillas rivers.

Vinasse application to sugar cane fields. Effect on the unsaturated zone and groundwater at Valle del Cauca (Colombia).

Extensive application of vinasse, a subproduct from sugar cane plantations for bioethanol production, is currently taking place as a source of nutrients that forms part of agricultural management in different agroclimatic regions. Liquid vinasse composition is characterised by high variability of organic compounds and major ions, acid pH (4.7), high TDS concentration (117,416-599,400mgL(-1)) and elevated EC (14,350-64,099μScm(-1)). A large-scale sugar cane field application is taking place in Valle del Cauca (Colombia), where monitoring of soil, unsaturated zone and the aquifer underneath has been made since 2006 to evaluate possible impacts on three experimental plots. For this assessment, monitoring wells and piezometers were installed to determine groundwater flow and water samples were collected for chemical analysis. In the unsaturated zone, tensiometers were installed at different depths to determine flow patterns, while suction lysimeters were used for water sample chemical determinations. The findings show that in the sandy loam plot (Hacienda Real), the unsaturated zone is characterised by low water retention, showing a high transport capacity, while the other two plots of silty composition presented temporal saturation due to La Niña event (2010-2011). The strong La Niña effect on aquifer recharge which would dilute the infiltrated water during the monitoring period and, on the other hand dissolution of possible precipitated salts bringing them back into solution may occur. A slight increase in the concentration of major ions was observed in groundwater (~5% of TDS), which can be attributed to a combination of factors: vinasse dilution produced by water input and hydrochemical processes along with nutrient removal produced by sugar cane uptake. This fact may make the aquifer vulnerable to contamination. Copyright © 2015 Elsevier B.V. All rights reserved.

[Correlation analysis of surnames and Y-chromosome genetic heritage in 3 provinces of southwestern Colombia].

PubMed

Gómez, Alberto; Avila, Sandra J; Briceño, Ignacio

2008-09-01

In Colombia, surnames are characters usually passed to the children by the father, and they have been compared to neutral alleles associated with the Y-chromosome. Population frequencies were determined for 17 short tandem repeats (STR) DNA markers on the Y-chromosome to compare the two identity codes and define the correlation between haplotypes and surnames in each individual. DNA was extracted from blood samples from 308 male individuals in provinces of Valle del Cauca, Cauca and Nariño, all in southwestern Colombia. Sample DNA was analyzed with the commercial kit AmpFLSTR Yfiler (Applied Biosystems) and examined for the following 17 Y-chromosome STR markers: DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385a/b, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS635 and Y-GATA-H4. The frequencies of molecular haplotypes were associated with the surname reported by each individual, and a correlation table was constructed. Amerindian and European surnames were associated with the presence of allele DYS19/13, a characteristic of Amerindian populations. Allele frequencies were reported for each of the 17 STR markers in the southwestern region of Colombia-high genetic and haplotypic diversities were obtained. Approximately 40% of lineage inconsistencies were found when the molecular genotype was compared with the European or Amerindian surnames. Surnames must be used as population markers with reservation. The genetic evidence indicates that traditional genealogies based on surnames with or without documental support, may be inconsistant with their biological provenance.

Colombia's space policy: An analysis of six years of progress and challenges

Becerra, Jairo

2014-07-01

This paper analyzes Colombia's space policy: its successes, its failures and what it still needs to achieve. The paper examines the interaction among the different players, and how this policy contributes to economic and social development of the country. And postulates that, unless a real national plan of action, with specific milestones and budget as well as a managing agency are developed, this policy may be in danger of disappearing. The Colombian Space Commission (Comisión Colombiana del Espacio, or CCE) was created by Presidential Decree 2442 in 2006. It is a multi-sectorial entity, in charge of coordinating, planning, and leading in the implementation of national policies for the development and application of space technologies. The CCE was also charged with the drafting of plans and programs in this field. The CCE began with only a few members (15) and today is comprised of 47 members: 13 ministries, 4 administrative departments, another 21 governmental entities and 9 universities, the latter acting as consultants. The Vice-President of the Republic is the President of the CCE. These different actors gave great importance to the development of Colombia's space sector, and 6 years later, they are continuing support and development the country's space policy. This analysis takes into account three aspects: first, achieving the objectives of the CCE: the creation and development of a national space policy for Colombia; secondly, focussing on “target groups” and “end users”; and thirdly, the “outcomes” or achievements to date. Some conclusions are worth highlighting: first, the warm reception and support of the CCE by both the public and private sectors on high levels, but the poor knowledge of the national space policy by the Colombian people and the small and medium companies. Secondly, in the context of public policy [9], the strategic plan called “National Policy in regard to Space Activities”, is caught between two phases: the formulation

Malaria is currently one of the most serious public health problems in Colombia with an endemic/epidemic transmission pattern that has maintained endemic levels and an average of 105,000 annual clinical cases being reported over the last five years. Plasmodium vivax accounts for approximately 70% of reported cases with the remainder attributed almost exclusively to Plasmodium falciparum. A limited number of severe and complicated cases have resulted in mortality, which is a downward trend that has been maintained over the last few years. More than 90% of the malaria cases in Colombia are confined to 70 municipalities (about 7% of the total municipalities of Colombia), with high predominance (85%) in rural areas. The purpose of this paper is to review the progress of malaria-eradication activities and control measures over the past century within the eco-epidemiologic context of malaria transmission together with official consolidated morbidity and mortality reports. This review may contribute to the formulation of new antimalarial strategies and policies intended to achieve malaria elimination/eradication in Colombia and in the region. PMID:21881765

Isla del Coco lies at 5 degrees 32'N latitude, 87 degrees 04'W longitude and is the sole peak of the Cocos Ridge exposed above sea level. This isolated island formed approximately 2 million years ago. It rises 575 m above the surface of the sea and covers 46 km2 (Castillo et aI., 1988). Five hundred km to the NNE is Costa Rica; 630 km SSW are the Galapagos Islands; 650 km to the E is Isla Malpelo, Colombia; and approximately 8,000 km W lie the Line Islands. Costa Rica claimed Isla del Coco in 1832 and declared it a National Park in 1978. The area of the park was increased to include the adjacent waters 5 km offshore in 1984 and 25 km offshore in 1991.

Colombia Country Analysis Brief

EIA Publications

2016-01-01

Colombia is South America's largest coal producer, and the region's third-largest oil producer after Venezuela and Brazil. In 2015, Colombia was the world's fifth-largest coal exporter. The country is also a significant oil exporter, ranking as the fifth-largest crude oil exporter to the United States in 2015. A series of regulatory reforms enacted in 2003 makes the oil and natural gas sector more attractive to foreign investors led to an increase in Colombian oil and natural gas production. The Colombian government implemented a partial privatization of state oil company Ecopetrol (formerly known as Empresa Colombiana de Petróleos S.A.) in an attempt to revive its upstream oil industry.

The public health context of violence in Colombia.

Garfield, Richard; Llanten Morales, Claudia Patricia

Among the countries of the Americas, Colombia has the highest level of deaths due to homicides and armed conflict. The objective of this research was to combine and contrast information from various sources on deaths due to violence in Colombia in order to identify major trends in violence in the country and to compare those trends with those in other nations of the Americas. We drew together information from a wide array of sources, including the Government of Colombia, Colombian forensic institutions, nongovernmental organizations, and international research centers. We considered the impact of the violence on mortality as well as in such areas as nonfatal injuries, displacement of persons, and kidnappings. While there have been many deaths in Colombia directly related to military conflict, there have been many more deaths and injuries as an indirect result of war. The highest levels of deaths directly related to violence occurred during the 1990-1995 period. Although deaths due directly to armed conflict declined in the late 1990s, the related events of kidnappings and displacement did not. Efforts to reduce the violence-related suffering in Colombia must consider both direct and indirect causes of mortality as well as nonfatal outcomes such as kidnappings and displacement.

Abstract We describe a new subspecies of Pale-bellied Tapaculo Scytalopus griseicollis from the northern Eastern Cordillera of Colombia and Venezuela. This form differs diagnosably in plumage from described subspecies Scytalopus griseicollis griseicollis and Scytalopus griseicollis gilesi and from the latter in tail length. It is also differentiated non-diagnosably in voice from both these populations. Ecological niche modelling analysis suggests that the new subspecies is restricted to the Andean montane forest and páramo north of both the arid Chicamocha valley and the Sierra Nevada del Cocuy.

Perinatal asphyxia is one of the main causes of perinatal mortality and morbidity worldwide and it generates high costs for health systems; however, it has modifiable risk factors. To identify the risk factors associated with the development of perinatal asphyxia in newborns at Hospital Universitario del Valle, Cali, Colombia. Incident cases and concurrent controls were examined. Cases were defined as newborns with moderate to severe perinatal asphyxia who were older than or equal to 36 weeks of gestational age, needed advanced resuscitation and presented one of the following: early neurological disorders, multi-organ commitment or a sentinel event. The controls were newborns without asphyxia who were born one week apart from the case at the most and had a comparable gestational age. Patients with major congenital malformations and syndromes were excluded. Fifty-six cases and 168 controls were examined. Premature placental abruption (OR=41.09; 95%CI: 4.61-366.56), labor with a prolonged expulsive phase (OR=31.76; 95%CI: 8.33-121.19), lack of oxytocin use (OR=2.57; 95% CI: 1.08 - 6.13) and mothers without a partner (OR=2.56; 95% CI: 1.21-5.41) were risk factors for the development of perinatal asphyxia in the study population. Social difficulties were found in a greater proportion among the mothers of cases. Proper control and monitoring of labor, development of a thorough partograph, and active searches are recommended to ensure that all pregnant women have adequate prenatal care with the provision of social support to reduce the frequency and negative impact of perinatal asphyxia.

To assess the cost-effectiveness of prophylactic administration of Granulocyte Colony-Stimulating Factor (G-CSF) compared with no use of it, during the induction phase of chemotherapy in Adults with Acute Lymphoblastic Leukemia (ALL) in Colombia. A decision tree with a time horizon of 30 days was built under colombian health system perspective including only direct costs. The costs of procedures and medications were taken from official sources and an institution of national reference of oncology services. The safety and effectiveness data were taken from the literature and two Colombian cohorts with patients older than 15 years. The unit of outcome was the proportion of deaths avoided. Base-case results on a clinical trial indicate that using factor is a dominant strategy. The variable that most impacted the outcome was the incidence of febrile neutropenia. Considering a threshold of $22.228 USD in 80% of cases using factor was cost effective. However, the use of factor is not cost-effective for the country for incidences of febrile neutropenia > 48%. It was not possible to establish cost-effectiveness of pegfilgrastim because no information was found. As per Colombian data, the use of prophylactic factor under chemotherapeutic induction in adults with ALL, turns out to be not cost effective. The difference in the results suggests the need of a careful extrapolation of information from clinical trials (ideal world) for developing economic evaluations in Colombia.

This study examines the process of deglaciation of the Western Massif of Picos de Europa through field work, geomorphological mapping, sedimentary records and absolute datings of 14C. This massif has several peaks over 2,400 m a.s.l. (Peña Santa de Castilla, 2,596 m; Torre Santa María, 2,486 m; Torre del Mediu, 2,467 m). It is composed mainly by Carboniferous limestones. This area has been intensively affected by karstic dissolution, Quaternary glaciers and fluvio-torrential processes (Miotke, 1968; Moreno et al, 2010; Ruiz-Fernández et al, 2009; Ruiz-Fernández, 2013). At present day, periglacial processes are active at the highest elevations (Ruiz-Fernández, 2013). We have identified four main glacial stages regarding the deglaciation of the massif: (i) maximum advance corresponding to the Last Glaciation, (ii) retreat and stabilization after the maximum advance, (iii) Late Glacial, and (iv) Little Ice Age. Sedimentological studies also contribute data to the understanding of the chronological framework of these environmental changes. The datings of the bottom sediments in two long sequences (8 and 5.4 m) provided a minimum age of 18,075 ± 425 cal BP for the maximum advance stage and 11,150 ± 900 cal BP for retreat and stabilization in the phase following the maximum advance.

State of emergency medicine in Colombia.

Arbelaez, Christian; Patiño, Andrés

Colombia is an upper-middle-income country with a population of 45 million people and one of the best national healthcare and medical education systems in South America. However, its widely diverse and difficult terrains hinder healthcare delivery to rural areas, creating disparities in healthcare access and outcomes between the urban and rural settings. Currently, emergency medical care is overwhelmingly provided by general practitioners without residency training, who obtain specialty consultations based on the medical/surgical condition identified. A few emergency medicine (EM) residency programs have sprouted over the last two decades in renowned academic institutions in the largest cities, producing high-quality EM specialists. With the establishment of EM as a specialty in 2005 and increasing recognition of the specialty, there has been an increasing demand for EM specialists in cities, which is only slowly being met by the current residencies. The critical challenges for EM in Colombia are both, establishing itself as a well-recognized specialty - by increasing academic production and reaching a critical mass of and unity among EM specialists - and providing the highest quality and safest emergency care to the people of Colombia - by improving capacity both in emergency departments and in the regional and national emergency response systems. Historically, the establishment of EM as a strongly organized specialty in other countries has spanned decades (e.g., the United States), and Colombia has been making significant progress in a similar trajectory.

Nevado del Huila, Columbia

NASA Technical Reports Server (NTRS)

2007-01-01

Nevado del Huila Volcano in Colombia is actually a volcanic chain running north to south, capped by a glacier. With peaks ranging in height from 2,600 to 5,780 meters (8,530 to 18,960 feet), Nevado del Huila is a stratovolcano composed of alternating layers of hardened lava, solidified ash, and volcanic rocks. Its first recorded eruption occurred in the mid-sixteenth century. The long-dormant volcano erupted again in mid-April 2007. A few months before the eruption, the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite captured this image of Nevado del Huila, on February 23, 2007. In this image, the bright white area just east of the central summit is ice. Immediately west of the summit are bare rocks, appearing as blue-gray. West of those rocks, white reappears, but this patch of white results from clouds hovering in the nearby valley. In the east, the colors turn to brown (indicating bare rock) and bright green (indicating vegetation). ASTER photographed Nevado del Huila near the end of a long phase of quietude. On April 17, 2007, local authorities recorded seismic activity associated with rock fracturing on the volcano's central summit, according to the ReliefWeb Website. Activity intensified the following day with an eruption and mudflows, forcing thousands of nearby residents to evacuate. As the Associated Press reported, the eruption caused avalanches and floods that wiped away both houses and bridges. It marked the volcano's first recorded eruption since the Spanish colonized the area five centuries earlier.

To report trends in mortality from suicide in Colombia from 1985 to 2002 by sex, age group, and method, and determine the number of Years of Potential Life Lost (YPLL) to suicide during this period. Age- and sex-specific and age-adjusted crude mortality rates were calculated based on mortality and population information available from the official database of the Department of National Statistics Administration, Colombia. YPLL were estimated and adjusted for societal impact, age, and poor quality of mortality records. The results were tabulated according to codes X600-X849 and Y870 from the International Statistical Classification of Disease and Related Health Problems, 10th revision (ICD-10), and codes E950-E959 from the 9th revision (ICD-9). Suicide rates have been climbing in Colombia since 1998, particularly among young adults and males. The highest rates among males were in the age groups 20-29 years of age and over 70 years of age, and rates increased over time. Among females, the highest rates were recorded for the group 10-19 years of age. The YPLL rose in proportion with the increase in suicides, from 0.81% in 1981 to 2.20% in 2002. Among males, the most common methods used were firearms and explosives, hanging, and poison, with a relative increase in hanging; whereas among females, poison was most common. A rising trend in suicide rates in Colombia was confirmed, especially among the productive segment of the population, which has resulted in a marked increase in YPLL.

Hernández Carrillo, Mauricio; Gutiérrez Martínez, María Isabel

2013-09-01

To determine the association between family and social relationships and School Bullying (SB) among peers in public education institutions in four municipalities of the department of Valle del Cauca, Colombia, during 2009. A case-control study matched by sex and educational institution was carried out. The study population came from a secondary database provided by the Departof Health Secretaryhealth, which consisted of data gathered in a survey of schoolchildren enrolled in grades 6 to 11. The CISNEROS scale and the Family APGAR test were applied to measure outcome and exposure variables. A conditional logistic regression model was obtained to explain SB. It was found that schoolchildren living with a family where verbal and physical violence prevails, as well as in a hostile neighborhood, are more vulnerable to SB. The probability of being an SB victim is explained by: family dysfunction (OR=2.67; 95%CI, 1.05-6.82), verbal aggression at home (OR=2.81; 95%CI, 1.45-5.46), physical punishing parents (OR=2.53; 95%CI, 1.12-5.75), and neighbors who are physically aggressive to each other (OR=1.87; 95% CI, 1.00-3.56). The study confirmed that reported by Lopez, who suggested that victimization and school rejection in adolescence is related to factors outside the classroom, such as the quality of communication between parents and children. As regards family influence in the SB, Bowes indicates that a positive family atmosphere is significantly associated with the resilience of school victimization. Furthermore, being physically punished by parents generates low self-esteem in the schoolchild that leads to lack of self-protective attitudes to the attacks that occur within the school.

Two peculiar new species of Heteranthera Ruiz & Pavón (Pontederiaceae) from Brazil, with notes on inflorescence architecture in the family

PubMed Central

Pellegrini, Marco O. O.; Horn, Charles N.

2017-01-01

Abstract Two new and peculiar species of Heteranthera are herein described. Heteranthera catharinensis is unique in the genus due to its glomerulate, many-flowered inflorescences, in which the flowers are restricted to the base and apex of the cincinni. It also possesses the biggest flowers in the H. reniformis Ruiz & Pavón species complex, with glabrous perianth lobes, medial filament, and style. On the other hand, Heteranthera pumila is described as the smallest known species of Pontederiaceae, with its dwarf stature, petiolate leaves with especially diminute blades, inflorescences 1–2–(3)-flowered, peduncle densely covered with glandular hairs, basal bract with glandular hairs at base, and smooth seeds, rarely possessing 7–9 inconspicuous longitudinal wings. We present detailed descriptions, illustrations, comments, a distribution map, conservation assessments for the new species, and an identification key to the Brazilian species of Heteranthera s.l. Finally, we discuss inflorescence morphology and terminology in Pontederiaceae, characterizing it as thyrsoid. PMID:28794681

Homicide is a universal indicator of social violence with large public health consequences. To describe mortality by homicides and to analyze its trends and geographic distribution in Colombia between 1998 and 2012. We conducted a descriptive study of deaths by homicide in Colombia between 1998 and 2012 using official mortality databases and the population projections of the Departamento Administrativo Nacional de Estadística, DANE. We calculated age- and sex-specific mortality rates, and we analyzed the geographical distribution of mean-adjusted homicide mortality rates at municipal level. Between 1998 and 2012, 331,470 homicides were reported in Colombia. The mean crude rate was 51.5 per 100,000 inhabitants: 95.9 in men and 8.2 in women. Since 2003, a decrease in the number of deaths and rates was observed; 91.9% of the victims were men and the highest mortality rates were reported in the 20-29 years old group. The most frequently involved mechanism was the firearm: Eight of 10 homicides in men, and seven of 10 homicides in women. Out of 1,122 municipalities, 186 were in the highest quintile, accumulating 50.1% of all deaths. In Colombia, homicides have been one of the leading causes of death with a trend towards reduction since 2002. Its geographical distribution has been heterogeneous. To continue addressing this public health issue we must recur to multidisciplinary analytical methodologies for a better understanding of the phenomenon.

Testa, J M; Montoya-Lerma, J; Cadena, H; Oviedo, M; Ready, P D

2002-12-01

The identity of the sandfly vectors of Leishmania braziliensis in Valle del Cauca Department, Colombia, was originally given as Lutzomyia townsendi, but then changed to L. youngi, another member of the L. townsendi series (Verrucarum group) with isomorphic females. To identify members of this series in Valle del Cauca, we analyzed the nuclear gene elongation factor-alpha (EF-alpha) and the mitochondrial gene cytochrome b (Cyt b). DNA sequences from the L. verrucarum series (L. columbiana, L. evansi and L. ovallesi) were used as outgroups. Flies from two locations on the western cordillera of the Andes were identified as L. townsendi s.s., according to male morphology and distinctive gene lineages. In the third location, on the central cordillera of the Andes, most specimens were identified as belonging to a geographical population of L. youngi, according to male morphology, an EF-alpha lineage shared with L. youngi from the Venezuelan-type locality, and a distinctive Cyt b sub-lineage. All other specimens were identified as L. youngi with the introgressed Cyt b sequences of L. townsendi. Such interspecific introgression implies that vectorial traits and ecological associations may no longer be viewed as fixed properties of different morphospecies.

Southwestern Colombia and northern Ecuador were shaken by a shallow-focus earthquake on 12 December 1979. The magnitude 8 shock, located near Tumaco, Colombia, was the largest in northwestern South America since 1942 and had been forecast to fill a seismic gap. Thrust faulting occurred on a 280- by 130-kilometer rectangular patch of a subduction zone that dips east beneath the Pacific coast of Colombia. A 200-kilometer stretch of the coast tectonically subsided as much as 1.6 meters; uplift occurred offshore on the continental slope. A tsunami swept inland immediately after the earthquake. Ground shaking (intensity VI to IX) caused many buildings to collapse and generated liquefaction in sand fills and in Holocene beach, lagoonal, and fluvial deposits.

1950-01-01

The following report summarizes data acquired during 1942-45, in Colombia, by geologists and engineers of the Foreign Economic Administration, with whom the United States Geological Survey cooperated. Twenty-nine mineral commodities are considered, but the data for five of them are scant because they were of no interest to FEA personnel. Petroleum is not considered. Preliminary to a review of individual mineral commodities, resumes are given of the general geography and geology of Colombia and of the country's mining laws. The principal mineral commodities, besides petroleum, produced in Colombia are (1) emeralds, gold, platinum, and silver, mainly for export, and (2) barite, cement, clay, coal, gypsum, salt, sand and gravel, silica, and stone, mainly for the domestic market. A large number of other mineral commodities are known in "raw" prospects, some of which may eventually become productive. Their distribution and apparent potentialities, as of 1945, are given. Factors unfavorable to mining are the ruggedness of the terrain, the scarcity of outcrops, and the very high transportation costs.

To analyze successful national smokefree policy implementation in Colombia, a middle income country. Key informants at the national and local levels were interviewed and news sources and government ministry resolutions were reviewed. Colombia's Ministry of Health coordinated local implementation practices, which were strongest in larger cities with supportive leadership. Nongovernmental organizations provided technical assistance and highlighted noncompliance. Organizations outside Colombia funded some of these efforts. The bar owners' association provided concerted education campaigns. Tobacco interests did not openly challenge implementation. Health organization monitoring, external funding, and hospitality industry support contributed to effective implementation, and could be cultivated in other low and middle income countries.

Hepatozoonosis is a tick-borne disease whose transmission to dogs occurs by ingestion of oocysts infected ticks or feeding on preys infested by infected ticks. Until now, there is no previous report of molecular characterization of Hepatozoon sp. in dogs from Colombia. EDTA blood samples were collected from 91 dogs from central-western region of Colombia (Bogotá, Bucaramanga, and Villavicencio cities) and submitted to 18S rRNA Hepatozoon sp. PCR and blood smears confection. Phylogenetic analysis was used to access the identity of Hepatozoon species found in sampled dogs. From 91 sampled dogs, 29 (31.8%) were positive to Hepatozoon sp. (25 dogs were only positive in PCR, 1 was positive only in blood smears, and 3 were positive in both blood smears and PCR). After sequencing, the found Hepatozoon sp. DNA showed 100% of identity with Hepatozoon canis DNA isolates. The phylogenetic tree supported the identity of the found Hepatozoon sp. DNA, showing that the isolates from Colombia were placed in the same clade than other H. canis isolates from Venezuela, Spain, and Taiwan. This is the first molecular detection of H. canis in dogs from Colombia.

The prevalence of Prediabetes in Colombia is high, and despite being recognized and categorized in the main Medical Guidelines and included in the International Classification of Diseases in Colombia, knowledge and awareness of it is limited amongst healthcare professionals and in the community. Our expert group recommends that educational programs emphasize a global approach to risk which includes a recognition of the importance of prediabetes and its evaluation along with and other risk factors such as a family history of DM2, overweight and obesity, dislipidemia and hypertension. Studies conducted in Colombia demonstrate the value of the FINDRIS questionnaire as a tool to identify subjects at risk of prediabetes and DM2, and we recommend that it should be systematic applied throughout the country as part of government policy. Prediabetes progresses to DM2 at an annual rate of 10%, but it has also been shown that prediabetes is an independent risk factor for cardiovascular outcomes. On this basis, the Committee recommends that once prediabetes is detected and diagnosed, immediate management of the disease begins through lifestyle changes, with follow up assessments performed at 3 and 6 months. If the patient does not respond with a weight loss of at least 5% and if the HbA1C values ​​are not normalized, pharmacological management should be initiated with a metformin dose of 500 mg / day, increasing up to 1,500 - 1,700 mg / day, according to tolerance.

Dengue in Colombia is an important public health problem due to the huge economic and social costs it has caused, especially during the disease outbreaks.  To describe the behavior of dengue mortality in Colombia between 1985 and 2012.  We conducted a descriptive study. Information was obtained from mortality and population projection databases provided by the Departamento Administrativo Nacional de Estadística (DANE) for the 1985-2012 period. Mortality rates, rate ratios, and case fatality rates were estimated.  A total of 1,990 dengue deaths were registered during this period in Colombia. Dengue mortality rates presented an increasing trend with statistical significance between 1985 and 1998. Higher mortality rates were reported in men both younger than 5 years and older than 65 years. Between 1995 and 2012, category 1 to 4 municipalities reported the highest mortality rates. Case fatality rates varied during the period between 0.01% and 0.39%.  Dengue is an avoidable disease that should disappear from mortality statistics as a cause of death. The event is avoidable if the proposed activities from the Estrategia de Gestión Integrada (EGI)-Dengue are implemented and evaluated. We recommend encouraging the development of an informational culture to contribute to decision making and prioritizing resource allocation.

Estimate price and income elasticities of aggregate demand for cigarettes in Colombia, by controlling for structural market changes since the late 1990s, to identify policy opportunities for taxes that could improve public health and increase tax revenues. Measurement of aggregate demand for cigarettes using gross income reported on value-added tax returns submitted to Colombia's National Tax and Customs Office (DIAN is the acronym in Spanish) by the tobacco product manufacturing industry, subtracting exports. A quarterly time series was obtained for the period 1994-2014. The econometric estimation using two-stage least squares controls for price endogeneity and uses a set of dummy variables to control for structural changes in the market and in its regulation. Demand is, from a statistical standpoint, sensitive to price and to income. Price elasticity of demand is -0.78 and income elasticity is 0.61. Inelastic demand implies that it is possible, through cigarette excise taxes, to meet public health targets and increase revenues simultaneously. The results also suggest that the considerable increase in household income in Colombia in the first decade of the 21st century increased purchasing power, which, lacking an accompanying tax increase, promoted cigarette consumption, with negative effects on public health, and wasted an opportunity to increase tax revenues.

2014-03-01

The international literature on the presence of arsenic (As) in Latin America does not disclose the true magnitude of the presence of As in Colombia. In this paper, we summarize the literature on As occurrence in Colombia. The data reveal that As is present in matrices such as soil, sediments and water and in the food chain. Some of the As concentrations exceed the limits specified by national and international regulations. Arsenic higher concentrations are associated with mining regions (e.g., soils, up to 148 mg/kg; sediments, up to 1400 mg/kg) and agricultural areas (e.g., vegetables, up to 5.40 mg/kg; irrigation water, up to 255 μg/L), and underscore the potential human and environmental risks associated with the presence of As in the country. This review highlights the importance of focusing research on understanding the occurrence, origin and distribution of As in Colombia to better understand its environmental and public health impact.

2012-01-01

Introduction: Breastfeeding promotion is one of the most important strategies against infant mortality and to control child undernourishment. Despite policies and plans to promote and protect breastfeeding in Colombia, its practice is low and its duration is short. Objective: To propose an ecology framework to interpret and incorporate contextual, interpersonal, and individual factors associated with the practice of breastfeeding and duration. Thereby, the plans and policies addressed to promote and protect breastfeeding in Colombia could be reinforced. Conclusions: To implement an ecology framework for Breastfeeding in Colombia, it is necessary to identify the effect of contextual factors in the biggest cultural regions of Colombia, to recognize the limitations of Infant-Friendly Hospital Initiatives to improve exclusive breastfeeding duration, to execute prospective studies in order to identify factors associated with breastfeeding duration, to design and implement plans and policies based on comprehensive planning strategies of healthcare interventions, to develop appropriate and cost-effective extra-institutional strategies aimed at prolonging the duration of breastfeeding, and to implement more reliable breastfeeding surveillance systems.

Local magnitude scale for Valle Medio del Magdalena region, Colombia

NASA Astrophysics Data System (ADS)

Londoño, John Makario; Romero, Jaime A.

2017-12-01

A local Magnitude (ML) scale for Valle Medio del Magdalena (VMM) region was defined by using 514 high quality earthquakes located at VMM area and inversion of 2797 amplitude values of horizontal components of 17 stations seismic broad band stations, simulated in a Wood-Anderson seismograph. The derived local magnitude scale for VMM region was: ML =log(A) + 1.3744 ∗ log(r) + 0.0014776 ∗ r - 2.397 + S Where A is the zero-to-peak amplitude in nm in horizontal components, r is the hypocentral distance in km, and S is the station correction. Higher values of ML were obtained for VMM region compared with those obtained with the current formula used for ML determination, and with California formula. With this new scale ML values are adjusted to local conditions beneath VMM region leading to more realistic ML values. Moreover, with this new ML scale the seismicity caused by tectonic or fracking activity at VMM region can be monitored more accurately.

Deafness on the island of Providencia - Colombia: different etiology, different genetic counseling.

Lattig, M C; Gelvez, N; Plaza, S L; Tamayo, G; Uribe, J I; Salvatierra, I; Bernal, J E; Tamayo, M L

2008-01-01

Providencia is a small island located in the Caribbean Ocean, northwest of Colombia with an unusually high frequency of individuals with hearing loss (5 in 1,000) is present. The hearing loss in the island was characterized as non-syndromic autosomal recessive deafness accounting for 47% (8/17) of the deaf population, Waardenburg Syndrome (deafness associated with pigmentary anomalies) for 29% (5/17), and the remaining 24% (4/17) are cases of sporadic non-syndromic deafness. For appropriate genetic counseling a complete pedigree of families with deaf individuals was constructed. The 35delG mutation in GJB2 gene, which encodes connexin 26 (Cx26), is responsible for the deafness observed in the 8 individuals with autosomal recessive non-syndromic hearing loss. The deaf individuals with Waardenburg Syndrome and the sporadic cases did not have this mutation. Therefore, we present here an atypical case of an isolated community with at least two different genetic etiologies for deafness: non-syndromic genetic deafness caused by the 35delG mutation in the GJB2 gene and deafness associated with Waardenburg Syndrome not related to GJB2. In a small and isolated population, it is feasible to assume that the deafness is caused by the same factor; however, Providencia is an atypical case. Therefore, it is extremely important to define the exact etiology of deafness in each case, since different etiologies require different genetic counseling.

A new species of Espeletiopsis (Millerieae, Asteraceae) from Colombia

Diazgranados, Mauricio; Sánchez, Luis Roberto

2013-01-01

Abstract A new species of Espeletiopsis was found in two small páramos of Norte de Santander, Colombia. The species is named Espeletiopsis diazii honoring the contributions of Santiago Díaz-Piedrahita in recognition of his vast knowledge of the Compositae in Colombia. This is a very distinctive species, markedly different from most of the Espeletiopsis present in Colombia. The new species is closely related to Espeletiopsis caldasii and Espeletiopsis santanderensis, but differs in having (1–)4–6(–7) capitula, with very short peduncles, and capitula arranged in a compact or densely glomerate cyme. With a total distribution area of less than 75 km2, this species is probably critically endangered or imperiled. PMID:24399905

2010-01-01

Five Anopheles marajoara Galvão and Damasceno populations, representing diverse ecological conditions, were sampled throughout Colombia and analyzed using nine hypervariable DNA microsatellite loci. The overall genetic diversity (H = 0.58) was lower than that determined for some Brazilian populations using the same markers. The Caquetá population (Colombia) had the lowest gene diversity (H = 0.48), and it was the only population at Hardy–Weinberg equilibrium. Hardy–Weinberg disequilibrium in the remaining four populations was probably caused by the Wahlund effect. The assignment analyses showed two incompletely isolated gene pools separated by the Eastern Andean cordillera. However, other possible geographical barriers (rivers and other mountains) did not play any role in the moderate genetic heterogeneity found among these populations (FST = 0.069). These results are noteworthy, because this species is a putative malaria vector in Colombia. PMID:20810825

The phlebotomine sand fly Lutzomyia velezi sp.nov. was described and illustrated from male specimens collected by light trap in the Reserva Natural Cañon del Río Claro in the Central Cordillera of the Colombian Andes. The new species belongs to the series sanguinaria of the subgenus Helcocyrtomyia, which is represented in Colombia by Lutzomyia cirrita, Lutzomyia hartmanni, Lutzomyia sanguinaria, Lutzomyia scorzai, Lutzomyia sp. of Pichindé and Lutzomyia tortura. The new species can be differentiated from others of the subgenus by the combination of the following characteristics: long antennal ascoids, reaching level of the papilla, coxite with a single basal seta and fifth palpomere longer than or equal to the sum of the lengths of the third and fourth palpomeres.

Mental health service delivery following health system reform in Colombia.

PubMed

Romero-González, Mauricio; González, Gerardo; Rosenheck, Robert A

2003-12-01

In 1993, Colombia underwent an ambitious and comprehensive process of health system reform based on managed competition and structured pluralism, but did not include coverage for mental health services. In this study, we sought to evaluate the impact of the reform on access to mental health services and whether there were changes in the pattern of mental health service delivery during the period after the reform. Changes in national economic indicators and in measures of mental health and non-mental health service delivery for the years 1987 and 1997 were compared. Data were obtained from the National Administrative Department of Statistics of Colombia (DANE), the Department of National Planning and Ministry of the Treasury of Colombia, and from national official reports of mental health and non-mental health service delivery from the Ministry of Health of Colombia for the same years. While population-adjusted access to mental health outpatient services declined by -2.7% (-11.2% among women and +5.8% among men), access to general medical outpatient services increased dramatically by 46%. In-patient admissions showed smaller differences, with a 7% increase in mental health admissions, as compared to 22.5% increase in general medical admissions. The health reform in Colombia imposed competition across all health institutions with the intention of encouraging efficiency and financial autonomy. However, the challenge of institutional survival appears to have fallen heavily on mental health care institutions that were also expected to participate in managed competition, but that were at a serious disadvantage because their services were excluded from the compulsory standardized package of health benefits. While the Colombian health care reform intended to close the gap between those who had and those who did not have access to health services, it appears to have failed to address access to specialized mental health services, although it does seem to have promoted a

2012-01-01

Background Although Coragyps atratus has been used as a traditional therapy for patients with cancer, the scientific literature does not contain enough information on how this therapy is used or the mechanisms that explain this therapeutic practice. Objectives To understand the methods of use and the reasons given by patients and caregivers for the use of Coragyps atratus in cancer treatment. Methods This study used a qualitative design based on twenty in-depth interviews of patients with cancer or caregivers of patients with the disease. The analysis of the text was based on an inductive thematic approach. Results Resistance to disease and immune enhancement are properties attributed to Coragyps atratus when used for cancer treatment. The most recommended method of use is fresh blood ingestion, and the associated mechanism of action is transfer of immune factors to the individual who consumes it. Conclusions Use of Coragyps atratus as a treatment for cancer is a popular alternative therapy in Colombia. More studies are needed to understand the clinical effects of this intervention in cancer patients.

Toxicosis by Plant Alkaloids in Humans and Animals in Colombia

Diaz, Gonzalo J.

2015-01-01

Due to its tropical location, chains of mountains, inter-Andean valleys, Amazon basin area, eastern plains and shores on both the Atlantic and Pacific Oceans, Colombia has many ecosystems and the second largest plant biodiversity in the world. Many plant species, both native and naturalized, are currently recognized as toxic for both animals and humans, and some of them are known to cause their toxic effects due to their alkaloid content. Among these, there are plants containing the hepatotoxic pyrrolizidine alkaloids, neurotoxins such as the indolizidine alkaloid swainsonine and the piperidine alkaloids coniine and γ-coniceine and tropane alkaloids. Unfortunately, the research in toxic plants in Colombia is not nearly proportional to its plant biodiversity and the scientific information available is only very scarce. The present review aims at summarizing the scarce information about plant alkaloid toxicosis in animals and humans in Colombia. PMID:26690479

2010-03-01

The purpose of this paper is to use data from the Global Youth Tobacco Survey (GYTS) conducted in Bogotá, Colombia, in 2001 and 2007 to examine changes in tobacco use among youth 13-15 years of age. The current tobacco control effort in Bogotá will be accessed relative to Colombia ratifying the World Health Organization Framework Convention on Tobacco Control (WHO FCTC) in 2008. GYTS was implemented in public schools in Bogotá, Colombia, by the Colombian National Cancer Institute. Data were collected from students in classrooms using self-administered procedures. Between 2001 and 2007, ever having smoked cigarettes decreased along with exposure to secondhand smoke (SHS) at home, having an object with a tobacco logo on it, and having been offered free cigarettes by a tobacco company representative. Prevalence of current cigarette smoking did not change from 2001 to 2007 (32.9% and 29.9%). Exposure to pro-tobacco advertising increased, reaching 71.4%, and 73.4% respectively, in 2007. Having been taught about the harmful effects of tobacco use did not change over time. The government of Colombia ratified the WHO FCTC in 2008. However, Colombia has one of the highest levels of cigarette smoking among 13-15 year olds in the Region of the Americas. The tobacco control effort in Colombia has much work to do, including recognition that the levels of smoking among adolescents are already as high as those of adults. Future declines in tobacco use among adolescents in Bogotá will likely depend on development of a comprehensive tobacco control program.

Assessing natural hazards in NE Colombia using Sentinel-1 interferometry

The DIGENTI project (Digitaler Entscheidertisch für das Naturgefahrenmanagement auf Basis von Satellitendaten und VGI (Volunteered Geographic Information)) aims to assess the natural hazard threat to the Cesar and La Guajira departments of northeast Colombia as guidance for decision makers and disaster relief workers. As members of the DIGENTI project, we use Sentinel-1 synthetic aperture radar (SAR) interferometry to detect hillslope movements, delineate settlements, and monitor damage to urban areas. Our study area, located in the remote Serranía del Perijá mountain range on the border of Colombia and Venezuela, is mountainous, highly vegetated, and experiences high and spatially variable rainfall (between 1 and 4 m a-1). The remote nature of the region, coupled with the favorable conditions for mass movements and other hillslope instabilities, make it an ideal location to employ remote sensing techniques to monitor potential natural hazards. In the highly vegetated Serranía del Perijá mountain range, traditional damage proxy mapping is complicated by vegetation-related coherence loss between SAR scenes. Cross-referencing existing maps, we define regions of consistently high coherence as settled or urban areas. Using the spatial extent of settled or urban areas as a mask, we establish an algorithm to use coherence loss only in these regions as a damage proxy in urban areas where the local population will be most affected. Outside of settlements, hillslope instabilities and movements are quantified and mapped using a two-prong approach: (1) Horizontal ground displacement is be calculated by dense amplitude cross-correlation using the topsOffsetApp in the InSAR Scientific Computing Environment (ISCE). This allows the location, direction, and magnitude of mass movements and hillslope instabilities to be identified and mapped; (2) We use a timeseries of interferograms to quantify vertical ground deformation (e.g., as caused by landsliding) during the Sentinel-1

Herein we describe a new species, Tillancoccus koreguajae Caballero & Ramos, sp. n. (Hemiptera: Coccidae) from Colombia collected on sugarcane. Pinnaspis strachani (Cooley) is also recorded on sugarcane for the first time worldwide. An updated list of seven species of Coccomorpha on sugarcane in Colombia is provided, including information on its distribution, biology, and mutualistic ants for each species. Seven species of scale insects (Hemiptera: Coccomorpha) have been recorded previously on sugarcane, Saccharum officinarum L. (Poaceae) in Colombia: Pseudococcidae: Dysmicoccus boninsis (Kuwana), D. brevipes (Cockerell), Pseudococcus calceolariae (Maskell), Saccharicoccus sacchari (Cockerell); Coccidae: Pulvinaria elongata Newstead; Diaspididae: Duplachionaspis divergens (Green) and Serenaspis minima (Maskell). However, the record of S. minima in Colombia is considered doubtful as there are no voucher specimens from Colombia and because the distribution of this species is currently limited to the Australasian region. Pseudococcus calceolariae is present in Colombia but its record on sugarcane is also doubtful. A taxonomic key for the identification of scale insects on sugarcane in Colombia is provided.

Moisture origin and transport processes in Colombia, northern South America

We assess the spatial structure of moisture flux divergence, regional moisture sources and transport processes over Colombia, in northern South America. Using three independent methods the dynamic recycling model (DRM), FLEXPART and the Quasi-isentropic back-trajectory (QIBT) models we quantify the moisture sources that contribute to precipitation over the region. We find that moisture from the Atlantic Ocean and terrestrial recycling are the most important sources of moisture for Colombia, highlighting the importance of the Orinoco and Amazon basins as regional providers of atmospheric moisture. The results show the influence of long-range cross-equatorial flow from the Atlantic Ocean into the target region and the role of the study area as a passage of moisture into South America. We also describe the seasonal moisture transport mechanisms of the well-known low-level westerly and Caribbean jets that originate in the Pacific Ocean and Caribbean Sea, respectively. We find that these dynamical systems play an important role in the convergence of moisture over western Colombia.

Geospatial-temporal distribution of Tegumentary Leishmaniasis in Colombia (2007–2016)

PubMed Central

Herrera, Giovanny; Pradilla, Iván; Vera, Mauricio

2018-01-01

Background Tegumentary Leishmaniasis (TL) is a neglected disease with worldwide distribution and considered a public health problem, especially in Latin America. In Colombia, the governmental epidemiological surveillance system (SIVIGILA) is responsible for collecting information on the presentation of cases of TL from each of the municipalities and departments. In absence of a study compiling and analyzing currently available metadata of TL in Colombia, this study describes the geospatial-temporal distribution of TL and identifies the regions of the country on which prevention measures should be established in order to control the disease. Methodology/Principal findings This is an exploratory descriptive analysis of the distribution of TL in Colombia. Information was collected on new cases of the disease during the years 2007–2016 from the Colombian reporting system (SIVIGILA). Incidence calculations were made based on population estimates by departments and biogeographical regions. Time evolution is shown in biennial maps. A 10-year series was analyzed, showing that the Amazon region is the most affected in terms of incidence, while the Andean region has the highest number of cases with a high variability among the departments that make it up. In those departments where there is a greater reported diversity of vector species, a large number of cases was observed. Conclusions/Significance Transmission dynamics of TL in Colombia in the past 10 years have been variable, with a greater concentration of cases in the central and southern departments. The present study contributes to improve the understanding of the patterns of distribution of TL in Colombia and can be a basis for future studies of impact evaluation of Health policies in the country and the region.

Organ for the biosynthesis of secondary metabolite is not always a place for its biosynthesis, even the same compound was synthesized in the different organs in different plants. Neolignan is a secondary metabolite, known as an imunostimulant, synthesized through shikimic acid pathway with the important precursor is chorismic acid. The compound was known to be accumulated in the roots, stems and leaves of Piper regnellii with the concentration varies depending on the type of neolignan. It has been investigated the accumulation of two compound neolignans (Pc-1 and Pc-2) isolated from the methanol extract of red betel leaf (Piper crocatum Ruiz & Pav.) in the leaves, stems, and flowers of red betel. Chromatographic methods used was Gas Chromatography-Mass Spectrometry (GC-MS). Chromatogram of GC-MS showed that the Pc-1 with purity of 100%, m/z 460.3 could be detected at the minute of 29.986, while the Pc-2 with purity of 96.681%, m/z 418.3 was detected at the minute of 29.495. The research was then continued to investigate the existence and accumulation of both compounds in leaves, stems, and flowers of red betel. The GC-MS chromatogram shows that Pc-1 and Pc-2 could be detected in the leaves, stem and flower with various concentration among plant organs. Moreover, leaves contained the highest concentration of Pc-1 and Pc-2 compared to other plant organs.

The aim of the present study was to estimate the economic impact of chikungunya virus (CHIKV) infection in Colombia from a societal perspective. We conducted a retrospective, bottom-up cost-of-illness study in clinically confirmed cases during the first chikungunya (CHIK) outbreak in Colombia in 2014. Direct and indirect costs were estimated per patient. Economic costs were calculated by the addition of direct costs (direct medical costs and out-of-pocket heath expenditures) and indirect cost as a result of loss of productivity. A total of 126 patients (67 children and 59 adults) with CHIK were included. The median of the direct medical cost in children was US$257.9 (interquartile range [IQR] 121.7-563.8), and US$66.6 (IQR 26.5-317.3) for adults. The productivity loss median expenditures reached US$81.3 (IQR 72.2-203.2) per adult patient. The median economic cost in adults as a result of CHIK was US$152.9 (IQR 101.0-539.6), of which 53.2% was a result of indirect costs. Out-of-pocket expenditures comprised 3.3% of all economic costs. Our study can help health decision makers to properly assess the burden of disease caused by CHIK in Colombia, an endemic tropical country. We recommend to strength the health information systems and to continue investing in public health measures to prevent CHIK. Copyright © 2018. Published by Elsevier Inc.

Self-mixing magma in the Ruiz Peak rhyodacite (New Mexico, USA): A mechanism explaining the formation of long period polytypes of mica

Pignatelli, I.; Faure, F.; Mosser-Ruck, R.

2016-12-01

The rhyodacite of Ruiz Peak Volcano (New Mexico, USA) is an exceptional rock because it contains both long period and short period polytypes of mica. Our petrographic study shows that this rhyodacite is characterized by numerous disequilibrium textures of phenocrysts (mica, amphibole, clinopyroxene, olivine and plagioclase) contained within both dark-grey and reddish coloured groundmass. The presence of two groundmasses, as well as of disequilibrium textures (reaction rims, resorption, dendritic, skeletal morphologies, etc.) suggests a complex magmatic history. These two types of groundmass are not due to a mixing of magmas but result from a degassing process during the magma ascent in the conduit. The disequilibrium textures are interpreted to be the result of small, short-lived convection cells in the magmatic chamber, which may allow crystal-crystal, crystal-spiral and spiral-spiral interactions to occur, leading to the formation of long period polytypes of mica. For the first time, the relationships between the crystallographic features of mica and the host-rock formation are underlined in this study. It follows that long period polytypes of mica can be considered markers of the complex history of magmas.

After the publication of the SISRA (CERESIS-1985) regional project, a unified catalog of seismic parameters and intensities for South America, researchers in historical seismicity have continued advancing on different scales in the area of this study of seismic hazard. The most important initiatives carried out in this area in Colombia and Venezuela can be grouped as follows: a) Reviews of destructive earthquakes in national and international historic archives, principally by Altez and FUNVISIS in Venezuela and Espinosa, Salcedo, and Sarabia et al in Colombia, leading to the preparation of seismologic catalogues, scientific and dissemination articles, reports, books, among others. b) Organization and systematization of historic information to develop public domain data bases and information, specifically the Historic Seismologic Teleinformation System in Venezuela, carried out between 2004 and 2008 under the coordination of Christl Palme and accessible on-line: http://sismicidad.ciens.ula.ve. As well, the "Historia Sísmica de Colombia 1550-1830" (Seismic History in Colombia 1550-1830) data base, in CD-ROM, by Espinosa Baquero (2003) and the historic seismicity information system of Colombia (Servicio Geológico Colombiano-Universidad Nacional de Colombia), published on the internet in 2012: http://agata.ingeominas.gov.co:9090/SismicidadHistorica/. c) Macroseismic studies for the development of intensity attenuation equations and the quantification and revaluation of basic historic earthquake parameters using isoseismal maps (Rengifo et al., Palme et al., Salcedo et al., among others) and procedures such as Boxer and Bakun & Wentworth (Palme et al., Dimaté, among others), which have produced significant changes in the parameters of some of the large earthquakes. d) Symposiums of researchers to promote interest and development in the discipline, including Jornadas Venezolanas de Sismología Histórica (Venezuelan Congress of Historical Seismology), held

Objective This article aims to analyze comparatively the national surveillance systems of water quality for human consumption (DWQS) of Brazil and Colombia, seeking to understand how practices are organized in these countries, along with their limits and possibilities. Methods The National Cross Comparison methodology was used with document analysis of secondary sources, with the purpose of discussing the similarities and differences between the two systems using the WHO’s Guidelines for Drinking Water Quality. Results The legal framework on DWQS in Brazil and Colombia was defined in the 70s and 80s, coinciding with the international visibility of this issue. Thereafter, DWQS practices in Brazil have been defined and organized in a national program, which has only recently started in Colombia. The current Brazilian and Colombian legislations show progress in technical elements that guide surveillance practices, such as the incorporation of risk assessment methodologies. The Colombian legislation defines the regulation of water supply services provision, which is not contemplated in Brazilian legislation. Elements such as decentralization, intersectionality, universality and right to information are included in the legislations of both countries, although further action on DWQS is needed. Conclusions Brazil and Colombia have similarities in the implementation of DWQS, despite being at different points in the implementation timeline. Actions on drinking-water quality surveillance are necessary to guarantee human rights related to the protection of the environment, such as universal access to drinking water, contributing to the promotion of health.

Heat flows were determined at 12 sites in four distinct areas between longitude 77?? and 80??W in eastern Panama and northwestern Colombia. Evidently, most of the region is underlain by mafic oceanic crust so that the crustal radiogenic component of heat flow is very small (??? 0.1 ??cal cm-2 sec-1). Low heat-flow values (??? 0.7 ??cal cm-2 sec-1) in northwestern Colombia may reflect thermal transients associated with shallow subduction. The normal values (??? 1) at about 78??W are consistent with the mean heat flow from the western Caribbean and the Gulf of Mexico. At 80??W, a fairly high value of 1.8 may define the easterly limit of thermal transients due to Cenozoic volcanic activity in Central America. ?? 1974.

2015-12-15

For more than two years, Corporación Nuevos Rumbos (Colombia) has been carrying out, in eight Colombian communities, a preventive system called Comunidades Que se Cuidan (CQC), an adaptation of Communities That Care (CTC), created at the University of Washington (Seattle), developed for more than 25 years in the United States of America and implemented in eight countries of America, Oceania, and Europe. The system is based on the public health approach, and the social development strategy for community empowerment. The core idea is to teach communities how to make decisions based on data regarding drugs and alcohol consumption and the identification of protective and risk factors, on the basis of the original survey validated in Colombia: these will allow communities to choose the best preventive interventions, tailored for each of them according to their needs. This paper describes the process of implementation of CQC in Colombia, its differences with CTC, the creation of Colombian cut-points, the main difficulties and how these were solved. CQC seems to be a preventive system with a wide potential applicability in other Latin American countries.

The objective of this study was to describe the network structure and factors associated with collaboration in two networks that promote physical activity (PA) in Brazil and Colombia. Organizations that focus on studying and promoting PA in Brazil (35) and Colombia (53) were identified using a modified one-step reputational snowball sampling process. Participants completed an on-line survey between December 2008 and March 2009 for the Brazil network, and between April and June 2009 for the Colombia network. Network stochastic modeling was used to investigate the likelihood of reported inter-organizational collaboration. While structural features of networks were significant predictors of collaboration within each network, the coefficients and other network characteristics differed. Brazil's PA network was decentralized with a larger number of shared partnerships. Colombia's PA network was centralized and collaboration was influenced by perceived importance of peer organizations. On average, organizations in the PA network of Colombia reported facing more barriers (1.5 vs. 2.5 barriers) for collaboration. Future studies should focus on how these different network structures affect the implementation and uptake of evidence-based PA interventions. Copyright © 2011 Elsevier Ltd. All rights reserved.

Preventing healthcare associated infections, especially for resistant microorganisms, is a priority. In Colombia, the surveillance of such events was started through a national pilot study. To describe the epidemiology of device-associated infections, bacterial resistance and antibiotic consumption patterns in institutions with intensive care units (ICU), 2011. Descriptive observational study in 10 health institutions from three Colombian provinces: Antioquia, Valle del Cauca, and Bogotá. Surveillance protocols were designed and implemented by trained health professionals in each hospital. A web tool was designed for data reporting and analysis. Infection rates, device-use percentages and antibiotics defined daily dose (DDD) were calculated. Bacterial resistance phenotypes and profiles were reported and analyzed using Whonet 5.6. The most common event was bloodstream infection (rate > 4.8/1000 catheter-days) followed by ventilator-associated pneumonia (VAP) and catheter-related urinary tract infection, showing a wide variability among institutions. A high consumption of meropenem in the ICU (DDD 22.5/100 beds-day) was observed, as well as a high carbapenem resistance (> 11.6%) and a high frequency of third generation cephalosporins resistance (> 25.6%) in Enterobacteriaceae in ICUs and hospitalization wards. The percentage of methicillin-resistant Staphylococcus aureus was higher in hospitalization wards (34.3%). This is the first experience in measuring these events in Colombia. It is necessary to implement a national surveillance system aimed at guiding governmental and institutional actions oriented to infection prevention and control, to resistance management and to the promotion of antibiotics rational use, along with a follow-up and monitoring process.

This paper reports on recent epidemiological observations in western Colombia, which further demonstrate the presence of naturally-occurring goitrogens contaminating water supplies in areas where goitre persists despite prolonged and continuous iodine supplementation. 'Prospective' and 'cross-sectional' studies in 41 localities where the populations have been on a uniform and adequate iodine supplementation for the last 10-20 years indicate that, in the endemia of western Colombia, environmental factors other than nutritional iodine deficiency are responsible for differences in goitre prevalence. Further epidemiological studies to determine the causal factors for the persistence of the endemia established a correlation between the sources of drinking water and goitre prevalence rates. Organic compounds containing sulfur with marked thionamide-like antithyroid activity were isolated from water supplying endemic goitre districts, and results are presented supporting the hypothesis that sedimentary rocks rich in organic matter are the main source of water-borne goitrogens. Bacteriological investigations showed that the presence of Klebsiella pneumoniae in drinking water and bacterial concentration were related significantly with goitre prevalence only in the presence of other variables, particularly the presence of sedimentary rocks. In the light of these epidemiological observations and experimental studies it may be concluded that, at present, endemic goitre in western Colombia is not due to nutritional iodine deficiency, but that water supplies are contaminated with sulfur-bearing organic compounds with thionamide-like antithyroid activity most probably deriving from sedimentary rocks rich in organic matter and that these compounds are the main factor underlying the endemia.

Suicide is a serious public health problem worldwide, affecting all population groups, regardless of age, gender, or area of residence. The aim of this investigation was to characterise the recorded suicides in Colombia, between the years 2000 and 2010, according to the variables of the person, time and place. Descriptive quantitative study with information from secondary sources, from the death certificates of deceased people by suicide registered with the National Bureau of Statistics. The behaviour of the deaths and mortality, were determined using the denominator population projections of Colombia and the Amazon, Andean, Atlantic Coast, Eastern Plains and Pacific regions. Descriptive measurements and mortality rates were calculated using these. A total of 24,882 suicides were recorded in the eleven years studied, with a mean of 6.2 people per day, which increased to 8.0 during holidays The mean age of death was 34.5 years (men 36.4, women 27.7), with male deaths (78.1%) and urban areas (66%) predominating. The greatest risk of dying from this cause was recorded in the Eastern Plains, in young adults and seniors, and residents in rural areas. Suicide rates in Colombia show a downward trend, with a mean of 5.3/100,000 inhabitants, and with an increased risk in men (3.7 times the risk in women, in young adults (9/100,000). A higher death rate was recorded in single people in the months of December and January, and at weekends. Copyright © 2015 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España.

OBJECTIVE: To investigate the relation between decentralization and equity of resource allocation in Colombia and Chile. METHODS: The "decision space" approach and analysis of expenditures and utilization rates were used to provide a comparative analysis of decentralization of the health systems of Colombia and Chile. FINDINGS: Evidence from Colombia and Chile suggests that decentralization, under certain conditions and with some specific policy mechanisms, can improve equity of resource allocation. In these countries, equitable levels of per capita financial allocations at the municipal level were achieved through different forms of decentralization--the use of allocation formulae, adequate local funding choices and horizontal equity funds. Findings on equity of utilization of services were less consistent, but they did show that increased levels of funding were associated with increased utilization. This suggests that improved equity of funding over time might reduce inequities of service utilization. CONCLUSION: Decentralization can contribute to, or at least maintain, equitable allocation of health resources among municipalities of different incomes. PMID:12751417

American cutaneous leishmaniasis (ACL) has been characterized as a zoonotic disease. However, peridomestic and domestic transmission have been recorded in at least nine countries in Central and South America. The present study was undertaken to identify the etiologic agent of a peridomestic epidemic of ACL in the Department of Tolima, Colombia. Leishmania isolates were obtained during the diagnosis of 56 patients with ACL who consulted the local leishmaniasis control program in three municipalities in Tolima. Species were identified using monoclonal antibodies and isoenzyme electrophoresis. A total of 53 (94.6%) of 56 isolates were identified as Leishmania (Viannia) guyanensis. Three isolates (5.4%) were identified as L. (V.) panamensis. Leishmania (V.) guyanensis is the probable etiologic agent of the largest epidemic of cutaneous leishmaniasis recorded in Colombia. This species has not previously been reported outside the Amazon and southeastern regions of Colombia, and has not been described in the peridomestic setting or linked with an epidemic.

A shore-based preliminary survey of marine ribbon worms (Nemertea) from the Caribbean coast of Colombia

Abstract A checklist of benthic ribbon worm species from the Caribbean coast of Colombia is presented, including synonyms, distributions, a photographic record, and the main morphologic characters of each species for a rapid identification. This is the first research focused broadly on nemerteans in Colombia. 54 specimens of nemerteans were hand-collected from the rocky littoral of two different localities, and identified according to personal experience and specialist literature. 13 species were found; of which 11 represent new records for the country. These species belong to eight different traditionally used families: Tubulanidae, Valenciniidae, Lineidae, Amphiporidae, Cratenemertidae, Emplectonematidae, Drepanophoridae and Ototyphlonemertidae. The most common and abundant species was Dushia atra. The biodiversity of nemerteans in Colombia seems to overlap with the nemertean fauna from Florida and Brazil, explained by the convergence of the North Brazil Current, Guiana Current, Caribbean Currents and the Panama-Colombia Contracurrent in the sampled region. The results of this work suggest that the Caribbean coast of Colombia is a region with a high diversity of nemerteans, and provide important taxonomic data for environmental assessments and future biological research.

Goldman, R

1987-04-01

2 male-only reproductive health clinics in Colombia are refuting the stereotype that Latin American men reject vasectomy as a threat to their machismo image and consider birth control to be a woman's responsibility. Over 1000 vasectomies were performed in the 2 clinics in Bogota and Medellin in 1986. The clinics are operated by PROFAMILIA and supported by the Association for Voluntary Surgical Contraception. Information about these male-only clinics is dispersed through radio announcements, magazine advertisements, and newspaper articles. The cost of services at these clinics is 50% less than services provided at other family facilities. These clinics demonstrate that Colombian men are willing to share family planning responsibilities if services are offered in a manner respectful of their needs. 3 additional male-only clinics are scheduled to open in Colombia in 1987.

Hepatitis E virus (HEV) is one of the main causes of acute viral hepatitis of enteric transmission. HEV has been detected in environmental samples in several countries from Europe and Asia, constituting a risk factor for waterborne infection. In Colombia, HEV has been identified in samples obtained from patients as well as from swine, but no environmental studies have been carried out. To determine if HEV is present in environmental waters, samples from the main source of drinking water plant and of wastewater system of eight municipalities and two villages of Antioquia state (North West Colombia), were collected between December 2012 and April 2014. The HEV genome was detected by RT-PCR in 23.3% (7/30) of the samples from the main source of drinking water plants and in 16.7% (5/30) from sewage. Viral concentrates obtained from three positive sewage samples were used to inoculate HepG2 cell cultures that were followed for one month; however, the viral genome was not detected in any cell culture. This study demonstrates the circulation of HEV in both source of drinking water plants and wastewater in Antioquia state, Colombia. The presence of HEV in environmental waters could be a risk for waterborne transmission in this population. The findings of the present study, together with the evidence of HEV circulation in human and swine in Colombia, should be consider by public health authorities for the development of surveillance programs and the inclusion of HEV infection diagnosis in the guidelines of viral hepatitis in the country. This is the first report of HEV in environmental samples in Colombia and the second one in Latin America. PMID:28520759

To quantify the magnitude and explain the trends and impact of death by homicide in Colombia and Mexico between 2000 and 2011 at the national level and by sex. Data were obtained from national homicide statistics (Departamento Administrativo Nacional de Estadística [DANE], Colombia; and Instituto Nacional de Estadística y Geografía [INEGI], Mexico). Standardized death rates and years of life lost (YLL) were calculated (the latter assuming zero mortality) in people 15–49 years old. In Colombia, between 2000 and 2002, deaths by homicide increased from 71.3 to 76.7 per 100 000 (7.5%); by 2011 this figure had fallen to 36.1. YLL in the same period increased to 0.58 years overall, reducing temporary life expectancy by one year in men and 0.1 years in women. Between 2002 and 2011, YLL was 0.45 years in both sexes: 0.83 in men and 0.07 in women. This decline occurred mainly in persons over 45 years of age. In Mexico, between 2000 and 2007, homicide rates fell from 10.8 to 8.2 per 100,000 and YLL dropped by 24%. Between 2008 and 2011, mortality and YLL increased significantly in both sexes (191.2% and 164.5%, respectively), reducing life expectancy by 0.39 years in men and 0.04 years in women. It was corroborated that there has been a decline in deaths by homicide in Colombia and a significant rise in Mexico after a period of continuous reduction. Numerous actions should be taken to continue reducing homicides in Colombia and to reverse the current trend in Mexico.

In this article we compare cooperation among Colombian and Swedish children aged 9–12. We illustrate the dynamics of the prisoner's dilemma in a new task that is easily understood by children and performed during a physical education class. We find no robust evidence of a difference in cooperation between Colombia and Sweden overall. However, Colombian girls cooperate less than Swedish girls. We also find indications that girls in Colombia are less cooperative than boys. Finally, there is also a tendency for children to be more cooperative with boys than with girls on average.

Advances in a study of sky quality for astronomical observations in Colombia

NASA Astrophysics Data System (ADS)

González-Díaz, D.; Pinzón, G.

2015-10-01

The aim of this study is to determine the sky quality in Colombia for astronomical observations in the optic. About 10,000 images in infrared (6.7 mu m and 10.7 mu m) were analyzed from the GOES meteorological satellites in three night times taken during a period of five years (2008 to 2014). A novel methodology was followed to determine how clear or covered was the sky in a given image. Meteorological data also were used from the weather stations network of the national meteorological institute, IDEAM. A correlation between threshold temperature and altitude was found for a historical data series of about 30 years. The results of the average percentage of nights with clear skies per year or clear sky fraction (CSF) were validated with the reports on the number of hours of astronomical observation from the logbooks of Llano del Hato Observatory in Merida-Venezuela, obtaining a cumulative percentage difference during the five years less than 10%. Annual cloud covering was computed over the whole country and it was classified the nights as clear or usable based on the definition of a quality factor.

The drink driving situation in Colombia.

PubMed

Castaño, Ramón

2012-01-01

To describe and analyze the drink driving situation in Colombia. The assessment was based on semistructured interviews of key stakeholders and analysis of secondary data. Road traffic crashes caused 5704 deaths and injured 39,318 people in 2010. The 3 main sources of crash data-forensic authorities, traffic authorities, and motor vehicle insurance agencies-provide different information about crashes, drivers, and victims, but they cannot be routinely merged. This together with the problem of identifying alcohol as the cause of a crash makes it difficult to estimate the role of drink driving in road crashes. In addition, reliable figures for the incidence of drink driving are not available from the random breath test programs because of sampling issues, underreporting, and missing data on negative results. However, it can be argued that alcohol plays a role in fatalities, because the proportion of crashes involving fatalities rises on weekends and between 12:00 a.m. and 05:59 a.m. when drink driving is likely to occur. Colombia has strict drink-drive laws that specify 3 levels of offense and sanctions (level I: 40- 99 mg/100 mL, level II: 100-149 mg/100 mL, and level III: 150 mg/100 mL or above). Drivers responsible for causing crashes with fatalities and injuries can be imprisoned under criminal law and sentences are increased by 50 to 100 percent if they test positive for alcohol. Enforcement includes random breath testing for alcohol, but its impact is weakened by the lack of a legal requirement to submit to a test and poor implementation of sanctions. There have been mass media campaigns against drink driving including one linked to a major enforcement initiative in 2008. However, there was a consensus that most campaigns were not focused sufficiently on increasing drivers' perceived risk of being caught. According to those interviewed, campaigns aimed at responsible consumption and the use of designated drivers appear to have had a growing positive effect, but

2010-07-01

Experimental efforts with fog collection in Colombia began eight years ago, and in recent papers we have suggested the implementation of operational fog collection as an alternative to meet water requirements in rural areas of the Andes Mountain Range. Since then, an increasing number of individuals from academia and environmental organizations in the country have shown a remarkable interest on this appropriate technology, and some started its exploration in a larger scale. In this work we describe the implementation process of the first operational fog collection project in Colombia and discuss its role in rural water supply, in environmental education issues and in the process of "social reintegration" of people who have been victims of forced displacement. Both the fog collection evaluation stage and construction and administration of the operational system involved the participation of the community of a rural village. The study zone, located in the Andes Mountains of the Valle del Cauca Department and with altitudes ranging from 2600 to 2800 meters a.s.l., has serious limitations in water availability. Eight standard fog collectors (SFC) were implemented and used during the period May/2008 - Feb/2009 in order to assess the water yield from fog. The best average monthly collection rate in the period of study was around 2.0 l.m-2.day-1. The constructed large fog collector (LFC), with a vertical collection surface of 25 m2, and the associated hydraulic system are currently managed and administered by the village inhabitants. The fog collection system benefits a rural school, and the water is mainly used in small-scale irrigation activities for horticultural crops and livestock development. The project has also brought positive impacts in the community organization, mainly comprising people who have been forced out of their rural homes by the country's nearly half-century old armed conflict. The system also allows agriculture- and environment-related issues to be

Describe and analyze the structural configuration of malaria in Colombia since 1960 to 2004 where the phenomena of persistence, resurgence and resistance as well as the main determinants associated to these phenomena. A comparative study of the history of malaria and its trend was conducted in Colombia since 1960-2004. Secondary and primary information about the frequency and spatial distribution of malaria was collected. The sub period were identified according to institutional transformation and malaria control strategies as well as the socioeconomic and sociopolitical conjuncture factors in the country. The structural and situational analyses of malaria in Colombia shown a steadily increase in morbidity from an average API 2,19 x 1 000 in 1960-74 to 8,92 by 1994-2004. Since the middle 70's there has been a considerable reduction of mortality. The malaria case relation P. vivax vs. P. falciparum is 3 to 5, respectively. The Annual Positive Sample Rate increased during the same study periods from 3.96% to 29.93%. Unfortunately the Annual Blood Examination Rate-ABER decreased by fewer than 5%, instead of increase to minimum required for detection of malaria. During the National Eradication Malaria Service the malaria decreased steadily by the first five years, unfortunately the disease present resurgence, persistence after the reduction of financial and technical support from international health agencies in the middle seventies. Nowadays, around 85% of the territory, mainly rural areas are endemic for malaria. In spite of the transformation of the health system and different strategies implemented against malaria, it continues being one of the priorities in the public health services of Colombia.

Colombia: reasons to create a national space agency

All modern nations are concerned with their independence, whether political, economic, or intellectual. That is why we support countries which are in the process of development becoming actively involved in the international space scene. Indeed, having limitations in industrial and technological exchange, we feel excluded today from key fields which hold promise for our future. The present moment is one of serious crises in Colombia's history. This paper thus proposes to demonstrate how the nation could, in an atmosphere free from fratricidal conflicts, exploit its space capabilities. We do not limit our focus to the scientific field, but also consider the social, economic and cultural aspects. The results of this research delineate how Colombia could start a new optimistic phase of its development, joining the international space programs within the framework of agreements among the regional governments in Latin America.

Income inequality is directly related to the mental health of the population. However, the relationship between income inequality and suicide rates in Colombia has still not been explored. To estimate the relationship between inequality and suicide rates in Colombia from 1994 to 2013. An ecological study was conducted, in which the correlation was estimated (Spearman) between inequality (Gini coefficient) and suicide rate between 1994 and 2013, according to official information available from the National Administrative Department of Statistics (DANE), and the National Institute of Forensic Science and Forensic Medicine. A Gini coefficient between 0.53 and 0.60 (median, 0.65 [interquartile range, 0.54-0.57]) was observed, and suicide rates were between 3.84 and 5.26 (median, 4.20 [4.08-4.86]). The correlation between inequality and suicide rates was positive and statistically significant (r=.70; p<.001). There is a positive association between economic inequality and suicide rate in Colombia. It is important to achieve greater equity in the distribution of income to reduce suicide rate in the country. Copyright © 2014 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España.

The known tick fauna of Colombia includes 58 species (15 Argasidae and 43 Ixodidae). To add to the knowledge of the biology of ticks in Colombia, hard ticks (Ixodidae) were collected from domestic animals or vegetation during 2014-2016 in 10 of Colombia's Departments. Ticks were identified to species through morphological examinations. Taxonomic identification was confirmed for some specimens by molecular methods, including phylogenetic analyses inferred from three tick genes (cytochrome c oxidase, 16S rDNA, second internal transcribed spacer). A total of 1745 tick specimens encompassing 8 species were collected. Overall, 5 tick species were recorded on cattle [Amblyomma dissimile, Amblyomma mixtum, Dermacentor nitens, Rhipicephalus microplus, Rhipicephalus sanguineus sensu lato (s.l.)], 5 on dogs (Amblyomma maculatum, Amblyomma ovale, Amblyomma varium, R. microplus, R. sanguineus s.l.), 3 on horses (A. mixtum, D. nitens, R. sanguineus s.l.), 3 on donkeys (A. mixtum, D. nitens, R. microplus), 1 on pig (D. nitens), and 2 from vegetation (A. mixtum, A. dissimile). This included the first records of A. mixtum from two Colombian Departments, indicating that the distribution of this tick in Colombia may be broader than currently known. Phylogenetic analyses confirmed that R. sanguineus s.l. specimens from 8 Departments belong to the "tropical species". Moreover, Colombian specimens of A. maculatum formed a large clade with GenBank sequences of A. maculatum and A. triste, although some Colombian specimens grouped with A. maculatum from the United States while others grouped with A. triste from Brazil. Significant polymorphisms were observed between specimens of A. ovale or D. nitens; for the former species, it is noteworthy that two distinct clades were observed. Our study provides new records for 8 tick species parasitizing domestic animals in Colombia, including species with veterinary and medical importance in the Neotropical region, such as R. microplus, R

Public policies in Colombia are inclined towards the well-being of the elderly, but this documental analysis concludes that the elderly Colombian is unprotected and defenseless against the obstacles and difficult situations due to the biological, political, social, economic and environmental conditions. This makes them vulnerable as it is a scheme that only benefits in cases of poverty and by being a member of the General Social Security in Health system, with transfer of obligations to the family, society and likewise the elderly.

Forecasting of Average Monthly River Flows in Colombia

NASA Astrophysics Data System (ADS)

Mesa, O. J.; Poveda, G.

2006-05-01

The last two decades have witnessed a marked increase in our knowledge of the causes of interannual hydroclimatic variability and our ability to make predictions. Colombia, located near the seat of the ENSO phenomenon, has been shown to experience negative (positive) anomalies in precipitation in concert with El Niño (La Niña). In general besides the Pacific Ocean, Colombia has climatic influences from the Atlantic Ocean and the Caribbean Sea through the tropical forest of the Amazon basin and the savannas of the Orinoco River, in top of the orographic and hydro-climatic effects introduced by the Andes. As in various other countries of the region, hydro-electric power contributes a large proportion (75 %) of the total electricity generation in Colombia. Also, most agriculture is rain-fed dependant, and domestic water supply relies mainly on surface waters from creeks and rivers. Besides, various vector borne tropical diseases intensify in response to rain and temperature changes. Therefore, there is a direct connection between climatic fluctuations and national and regional economies. This talk specifically presents different forecasts of average monthly stream flows for the inflow into the largest reservoir used for hydropower generation in Colombia, and illustrates the potential economic savings of such forecasts. Because of planning of the reservoir operation, the most appropriated time scale for this application is the annual to interannual. Fortunately, this corresponds to the scale at which hydroclimate variability understanding has improved significantly. Among the different possibilities we have explored: traditional statistical ARIMA models, multiple linear regression, natural and constructed analogue models, the linear inverse model, neural network models, the non-parametric regression splines (MARS) model, regime dependant Markovian models and one we termed PREBEO, which is based on spectral bands decomposition using wavelets. Most of the methods make

The present work is part of a process to create a Catalogue of the Freshwater Fishes of Colombia and consisted in the depuration and updating of the taxonomic and geographic components of the checklist of the freshwater fishes of Colombia. An exhaustive revision of the 1435 species recorded in 2008 was necessary to: 1. Add new species described since 2009 and species originally described from Colombia but inadvertently omitted in 2008; 2. Add new records of already described species; 3. Delete species whose presence in Colombia was not supported by voucher specimens in ichthyological collections; and 4. Revise the geographic distribution of the species listed in 2008. This process resulted in the following numbers: 1. Total number of freshwater fish species in Colombia: 1494; 2. Number of species recorded by hydrographic region - Amazon: 706, Orinoco: 663, Caribbean: 223, Magdalena-Cauca: 220, Pacific: 130; and 3. Number of endemic species: 374 (76% from the trans-Andean region). Updating the current checklist is a fundamental requirement to ensure its incorporation in the decision-making process with regard to the conservation of Colombian aquatic species and ecosystems, which are facing transformation processes as a result of activities such as mining, construction of hydroelectric plants, expansion of the agricultural frontier and subsequent deforestation, industrial and domestic pollution, development of waterways, introduction of exotic species, and climate change.

Rodríguez, Deysi Yasmin; Fernández, Francisco José; Acero Velásquez, Hugo

2003-01-01

Road traffic injuries are a leading public health problem in Colombia. Pedestrians are the most vulnerable road users, especially in the main urban centers of Bogotá, Medellin and Cali. Data analyzed in this report include official statistics from the National Police and the National Institute of Legal Medicine and Forensic Sciences for 1996-2000, and results of a study conducted at the National University of Colombia in 2000. Methods from the Highway Capacity Manual were used for determining physical and technical variables, and a Geographical Information System tool was used for the location and spatial analysis of the road traffic crashes. Pedestrians accounted for close to 32% of injuries and 40% of the deaths from road traffic crashes. The problem of road traffic crashes existed predominately in urban areas. In the main urban centers, pedestrians constituted nearly 68% of road traffic crash victims. The high level of risky road use behaviors demonstrated by pedestrians and drivers, and inadequate infrastructure for safe mobility of pedestrians in some sections of the road network were the main contributing factors. Major improvements were achieved in Bogotá following enhancements to the municipal transport system and other policies introduced since 1995. In conclusion, policies and programs for improving road safety, in particular pedestrian safety, and strengthening urban planning are top priority.

2011-01-01

The implementation of national EHR infrastructures has to start by a detailed definition of the overall structure and behavior of the EHR system (system architecture). Architectures have to be open, scalable, flexible, user accepted and user friendly, trustworthy, based on standards including terminologies and ontologies. The GCM provides an architectural framework created with the purpose of analyzing any kind of system, including EHR system´s architectures. The objective of this paper is to propose a reference architecture for the implementation of an integrated EHR in Colombia, based on the current state of system´s architectural models, and EHR standards. The proposed EHR architecture defines a set of services (elements) and their interfaces, to support the exchange of clinical documents, offering an open, scalable, flexible and semantically interoperable infrastructure. The architecture was tested in a pilot tele-consultation project in Colombia, where dental EHR are exchanged.

To study the epidemiology of Treponema pallidum (syphilis) among female sex workers (FSW) in Santa Fe de Bogotá, Colombia. A cross-sectional study was conducted. Participants were interviewed using a standardized questionnaire, which collected socio-demographic characteristics and risk behavior information. Blood samples were screened for syphilis using the VDRL test and the MHATP assay. The prevalence of syphilis was 10.3% (53/514). Adjusted risk factors significantly associated with syphilis were: age (linear increase), education (primary or no education), monthly income (or=4 years), number of clients per week (>or=22), main workplace (street), inconsistent (never) condom use in sex work, previous STI history, and use of illegal drugs. Effective health education programs for improving the level of knowledge of STI and the promotion of consistent condom use activities along with other appropriate harm reduction activities are urgently required among FSW in Colombia.

1996-01-01

Lutzomyia longipalpis, 15 other species of the genus Lutzomyia, and one species of Brumptomyia were collected in an endemic focus of cutaneous leishmaniasis in a river canyon 450 m above sea-level, in Rio Claro, Antioquia, Colombia. The presence of Lu. longipalpis is associated with the destruction of the primary forest and the development of new farmland and rural settlement in this region. The composition of species identified a different habitat for Lu. longipalpis in Colombia. Lu. yuilli and Lu. longipalpis were predominant (68.26%) followed by Lu. trapidoi, Lu. hartmani, Lu. triramula, Lu. panamensis, Lu. gomezi.

Objective To analyze successful national smokefree policy implementation in Colombia, a middle income country. Materials and methods Key informants at the national and local levels were interviewed and news sources and government ministry resolutions were reviewed. Results Colombia’s Ministry of Health coordinated local implementation practices, which were strongest in larger cities with supportive leadership. Nongovernmental organizations provided technical assistance and highlighted noncompliance. Organizations outside Colombia funded some of these efforts. The bar owners’ association provided concerted education campaigns. Tobacco interests did not openly challenge implementation. Conclusions Health organization monitoring, external funding, and hospitality industry support contributed to effective implementation, and could be cultivated in other low and middle income countries.

The influence of the tropical Pacific SST on precipitation in Colombia is examined using 341 stations covering the period 1979-2009. Through a Singular Value Decomposition (SVD) the two main coupled variability modes show SST patterns clearly associated with El Niño (EN) and El Niño Modoki (ENM), respectively, presenting great coupling strength with the corresponding seasonal precipitation modes in Colombia. The results reveal that, mainly in winter and summer, EN and ENM events are associated with a significant rainfall decrease over northern, central, and western Colombia. The opposite effect occurs in some localities during spring, summer, and autumn. The southwestern region of Colombia exhibits an opposite behaviour connected to EN and ENM events during years when both events do not coexist, showing that the seasonal precipitation response is not linear. The Partial Regression Analysis used to quantify separately the influence of the two types of ENSO on seasonal precipitation shows the importance of both types in the reconstruction process. The results obtained in this study establish the base for modeling and forecasting the seasonal precipitation in Colombia using the tropical Pacific SST associated with El Niño and El Niño Modoki. Keywords: Seasonal precipitation, Tropical Pacific SST, El Niño, El Niño Modoki, Singular Value Decomposition, Colombia.

While conflict-induced forced migration is a global phenomenon, the situation in Colombia, South America, is distinctive. Colombia has ranked either first or second in the number of internally displaced persons for 10 years, a consequence of decades of armed conflict compounded by high prevalence of drug trafficking. The displacement trajectory for displaced persons in Colombia proceeds through a sequence of stages: (1) pre-expulsion threats and vulnerability, (2) expulsion, (3) migration, (4) initial adaptation to relocation, (5) protracted resettlement (the end point for most forced migrants), and, rarely, (6) return to the community of origin. Trauma signature analysis, an evidence-based method that elucidates the physical and psychological consequences associated with exposures to harm and loss during disasters and complex emergencies, was used to identify the psychological risk factors and potentially traumatic events experienced by conflict-displaced persons in Colombia, stratified across the phases of displacement. Trauma and loss are experienced differentially throughout the pathway of displacement.

In this paper we investigate CO 2 emission scenarios for Colombia and the effects of implementing carbon taxes and abatement targets on the energy system. By comparing baseline and policy scenario results from two integrated assessment partial equilibrium models TIAM-ECN and GCAM and two general equilibrium models Phoenix and MEG4C, we provide an indication of future developments and dynamics in the Colombian energy system. Currently, the carbon intensity of the energy system in Colombia is low compared to other countries in Latin America. However, this trend may change given the projected rapid growth of the economy and the potential increasemore » in the use of carbon-based technologies. Climate policy in Colombia is under development and has yet to consider economic instruments such as taxes and abatement targets. This paper shows how taxes or abatement targets can achieve significant CO 2 reductions in Colombia. Though abatement may be achieved through different pathways, taxes and targets promote the entry of cleaner energy sources into the market and reduce final energy demand through energy efficiency improvements and other demand-side responses. The electric power sector plays an important role in achieving CO 2 emission reductions in Colombia, through the increase of hydropower, the introduction of wind technologies, and the deployment of biomass, coal and natural gas with CO 2 capture and storage (CCS). Uncertainty over the prevailing mitigation pathway reinforces the importance of climate policy to guide sectors toward low-carbon technologies.

Dengue has a seasonal behavior associated with climatic changes, vector cycles, circulating serotypes, and population dynamics. The wavelet analysis makes it possible to separate a very long time series into calendar time and periods. This is the first time this technique is used in an exploratory manner to model the behavior of dengue in Colombia.  To explore the annual seasonal dengue patterns in Colombia and in its five most endemic municipalities for the period 2007 to 2012, and for roughly annual cycles between 1978 and 2013 at the national level.  We made an exploratory wavelet analysis using data from all incident cases of dengue per epidemiological week for the period 2007 to 2012, and per year for 1978 to 2013. We used a first-order autoregressive model as the null hypothesis.  The effect of the 2010 epidemic was evident in both the national time series and the series for the five municipalities. Differences in interannual seasonal patterns were observed among municipalities. In addition, we identified roughly annual cycles of 2 to 5 years since 2004 at a national level.  Wavelet analysis is useful to study a long time series containing changing seasonal patterns, as is the case of dengue in Colombia, and to identify differences among regions. These patterns need to be explored at smaller aggregate levels, and their relationships with different predictive variables need to be investigated.

The Software Industry in the Coffee Triangle of Colombia

Cuesta, Albeiro; Joyanes, Luis; López, Marcelo

The so-called "Coffee Triangle" region is located in the Andean Region, in central Colombia, South America. This Andean Region is composed of the Departments of Caldas, Quindío and Risaralda. The Andean Region has been characterized by the production of coffee as a worldwide industry supported by high Quality and Research standards. These components have become the key bastions to compete in international markets. After the decline of the Coffee industry it is necessary to consider alternatives, supplemented by the success of the Software Industry at the global level. The strengthening of the Software Industry in the Coffee Triangle seeks to establish a productive alternative for regional growth in a visionary way, where knowledge, a fundamental input of the Software Industry, is emerging as one of the greatest assets present in this geographical area - Andean Region - of Colombia.

Abstract Introduction: The risk of developing breast and ovarian cancer is higher in families that carry mutations in BRCA1 or BRCA2 genes, and timely mutation detection is critical. Objective: To identify the presence of mutations in the Colombian population and evaluate two testing strategies. Methods: From a total universe of 853 individual blood samples referred for BRCA1 and BRCA2 typing, 256 cases were analyzed by complete direct sequencing of both genes in Myriad Genetics, and the remaining 597 cases were studied by partial sequencing based on founder mutations in a PCR test designed by ourselves ("Profile Colombia"). Results: We found 107 patients carrying deleterious mutations in this group of patients, 69 (64.5%) located in BRCA1, and 38 (35.5%) in BRCA2. Overall, we detected 39 previously unreported mutations in Colombia (22 in BRCA1 and 17 in BRCA2) and only 4 out of the 6 previously reported founder mutations. Sixty four out of 597 patients (10.7%) studied by "Profile Colombia" showed mutations in BRCA1 or BRCA2, and 41/256 patients (16%) showed mutations by complete BRCA1-BRCA2 sequencing. Conclusions: The spectrum of 44 different mutations in Colombia as detected in our study is broader than the one previously reported for this country. "Profile Colombia" is a useful screening test to establish both founder and new mutations (detection rate of 10.7%) in cases with family history of breast cancer. Complete sequencing shows a detection rate of 16.0%, and should complement the study of the genetic basis of this disease. PMID:29021639

Social effects of labour migration: the Colombia experience.

PubMed

Cely Martinez, J N

1989-06-01

Colombia has traditionally been classified as a net exporter of manpower. However, the US's restrictions on immigration and the economic crisis in Venezuela, Colombia's sister republic, have affected both the volume and composition of emigration. It could be initially concluded that despite domestic difficulties and external problems, favorable economic prospects explain the present reduced outflow of immigrants. On the basis of a sample survey of applications taken during the last 2 years, 94% of arrivals were classified as professionals and technicians; the remainder were administrative workers. This achievement (which contrasts with high levels of unemployment among Colombian professionals) reflects new technological innovations. It appears that while Colombia exports engineers, it imports engineering. Opinion surveys conducted among employers, migrants, and educational authorities show that costs are not fully compensated by the migrant's improved standard of living in the country of destination, even if he has sent remittances to his country of origin. Investments in education and training yield no returns to the country if the recipient emigrates. The advantages of emigration, identified in the same surveys, include 1) reduction in internal pressure on the labor market, 2) improvement in the incomes of those who do not emigrate, and 3) resolution of economic problems for migrants. The Social Economics Plan implemented by the current government indirectly affects migratory processes by focusing on: 1) eradication of poverty; 2) the National Rehabilitation Plan, by which regional growth is stimulated in poor and economically precarious districts; and 3) the Integral Rural Development Plan which aims to eradicate poverty and improve production and commercialization in small-holding areas. The author concludes that the effects of migration on social structures must be examined in depth.

Illegal drugs, anti-drug policy failure, and the need for institutional reforms in Colombia.

PubMed

Thoumi, Francisco E

2012-01-01

This paper is inspired by two anomalies encountered in the study of the illegal drugs industry. First, despite the very high profits of coca/cocaine and poppy/opium/heroin production, most countries that can produce do not. Why, for example, does Colombia face much greater competition in the international coffee, banana, and other legal product markets than in cocaine? And second, though illegal drugs are clearly associated with violence, why is it that illegal drug trafficking organizations have been so much more violent in Colombia and Mexico than in the rest of the world? The answers to these questions cannot be found in factors external to Colombia (and Mexico). They require identifying the societal weaknesses of each country. To do so, the history of the illegal drugs industry is surveyed, a simple model of human behavior that stresses the conflict between formal (legal) and informal (socially accepted) norms as a source of the weaknesses that make societies vulnerable is formulated. The reasons why there is a wide gap between formal and informal norms in Colombia are explored and the effectiveness of anti-drug policies is considered to explain why they fail to achieve their posited goals. The essay ends with reflections and conclusion on the need for institutional change.

The bionomics of sand flies (Diptera: Phlebotominae) was studied monthly for two consecutive years in alluvial gallery forests in the department of Casanare, Northeastern Colombia. A total of 2,365 specimens and 10 species were captured using CDC light traps and Shannon traps, and from diurnal resting places, and human landing collections. Lutzomyia fairtigi Martins (55%), Lutzomyia micropyga (Mangabeira) (20.9%), and Lutzomyia antunesi (Coutinho) (13.5%) were the predominant species in the region. Lutzomyia flaviscutellata and Lutzomyia panamensis, potential vectors of Leishmania in Colombia and neighboring countries, were also collected, but in low numbers. Lu. fairtigi is an endemic species to Colombia, and minimal data are available on its biology and distribution. The present study provides additional information about Lu. fairtigi, such as the diurnal activity displayed by females on cloudy days, the greater density during the rainy season (April to October), marked anthropophilia, and the presence of flagellates in the midgut of one female.

During the last 2 years, the Colombian government and the Nuevos Rumbos Corporation have been implementing an adapted version of the Communities That Care (CTC) prevention system, called Comunidades Que se Cuidan (CQC) in Spanish, for use in Colombia. This brief report presents the process of implementing CQC and identifies some of the main challenges and achievements of implementing the system in eight communities in Colombia. Preliminary results of a pilot study of CQC implementation in Colombia show that prevention system development, including a focus on measuring community risk and protection, can be established successfully in Latin American communities despite a lack of rigorously tested prevention programs and strategies. Moreover, mobilizing community coalitions toward science-based prevention, with a focus on examining local risk and protective factor data, can spur development and evaluation of prevention efforts in Latin America.

Physiological resistance of natural population of Aedes aegypti to insecticides contribute to the decreased efficacy of chemical control as a main control strategy during dengue outbreaks. The susceptibility status of Ae. aegypti was assessed for the carbamate propoxur, the adulticide malathion and the larvicide temephos on 13 natural populations of Ae. aegypti immature forms were taken from 8 Colombian localities. These included the following: Bucaramanga (1), Sabana de Torres (2), Girardot (2), La Mesa (2), Villavicencio (2), Puerto López (2), San José del Guaviare (1) and Florencia (1). Susceptibility tests mainly consisted of the standardized bioassay outlined by WHO (1981) and CDC bottles (1998). Colorimetric tests were undertaken to determine enzyme levels possibly responsible for the reduction of susceptibility to organophosphate and carbamate insecticides. All specimens demonstrated susceptibility to malathion and propoxur insecticides. Four of the 13 populations revealed susceptibility to the temephos larvicide. Seven of 11 populations showed a limited increase in values for nonspecific esterase enzymes. The Bucaramanga population was the only one which showed an increase in the cytochrome P450 monooxygenases enzymes. Neither population was found with modified acetilcolinesterase. The widespread susceptibility to organophosphates used as adulticides indicated that malathion, the most used insecticide in Colombia, remains effective in interrupting the transmission of dengue. Physiological resistance to insecticides occurring in communities of a single township proved to be a localized phenomenon.

This study aims to understand the migratory experience and the employment, work and health conditions of the returned migrants from Spain to Colombia. A qualitative study was conducted by means of 23 semi-structured interviews with Colombian returned migrant workers. Qualitative narrative content analysis was performed using Atlas.Ti software. Main findings are represented by nine categories emerged from the participants' discourses: (1) impact of the economic crisis on work and employment conditions in Spain, (2) economic crisis and return, (3) characteristics of returnees, (4) perception of the returnees about Colombia, (5) the role of social support networks, (6) employment and working conditions in Colombia, (7) health and wellbeing, (8) future plans and expectations, (9) the experience of being immigrant. Adjustment difficulties in participants are evidenced by the return migration process and the conditions of the social, political and economic system in Colombia. Return migration represents the reconfiguration of personal and working lives of this population. This situation requires the development of global policies and strategies in public health to facilitate the adaptation of these people.

Objective Maternal mortality reduction is a Millennium Development Goal. In Colombia, there is a large disparity in the maternal mortality ratio (MMR) between and into departments (states) and also between municipalities. We examined socioeconomics variables at the municipal and departmental levels which could be associated to the municipal maternal mortality in Colombia. Methods A multilevel ecology study was carried out using different national data sources in Colombia. The outcome variable was the MMR at municipal level in 2011 with multidimensional poverty at municipal and department level as the principal independent variables and other measures of the social and economic characteristics at municipal and departmental level were also considered explicative variables (overall fertility municipal rate, percentage of local rural population, health insurance coverage, per capita territorial participation allocated to the health sector, transparency index and Gini coefficient). The association between MMR and socioeconomic contextual conditions at municipal and departmental level was assessed using a multilevel Poisson regression model. Results The MMR in the Colombian municipalities was associated significantly with the multidimensional poverty (relative ratio of MMR: 3.52; CI 95%: 1.09-11.38). This association was stronger in municipalities from departments with the highest poverty (relative ratio of MMR: 7.14; CI 95%: 2.01-25.35). Additionally, the MMR at municipal level was marginally associated with municipally health insurance coverage (relative ratio of MMR: 0.99; CI 95%: 0.98-1.00), and significantly with transparency index at departmental level (relative ratio of MMR: 0.98; CI 95%: 0.97-0.99). Conclusion Poverty and transparency in a contextual level were associated with the increase of the municipal MMR in Colombia.

During pregnancy, the need for certain nutrients increases. This study assessed the prevalence and socio-demographic factors associated with dietary supplement use in a representative sample of pregnant women in Colombia. Data for this study were obtained from a cross-sectional, nationally representative survey (ENSIN, 2010). A total of 1856 pregnant women, 13-49 years of age, were recruited. The use of prenatal dietary supplements (Vitamins A, C or E) was treated as a binary outcome (used at some time or never sued during pregnancy when prescribed by a doctor) in multinomial analyses. Sociodemographic data and associated factors were assessed by computer-assisted personal interview technology. Of the sample, 1123 women (68.6%) reported taking prenatal dietary supplements at some stage during their pregnancy. Most users had a high socioeconomic level (79.5%), were in their third trimester of pregnancy (79.5%), were 30-49 years of age (74.0%), and lived in the central region of Colombia (73.8%). The multivariate logistic regression showed that third trimester of pregnancy (OR 6.2;95% CI 4.0 to 9.3), high educational level (OR 2.3; 95% CI 1.5 to 3.4), high socioeconomic level -SISBEN IV or more- (OR 2.0; 95% CI 1.4 to 2.8), residence in the Atlantic region (north) (OR 2.6; 95% CI 1.7 to 3.6), Eastern region (OR 2.0; 95% CI 1.3 to 3.1), central region (OR 2.6; 95% CI 1.7 to 3.9), Pacific region (west) (OR 1.5; 95% CI 1.0 to 2.3), and belonging to the mestizo (others) ethnic group (OR 1.2; 95% CI 1.0 to 2.6), were all associated with a higher probability of dietary supplement intake. The prevalence of prenatal dietary supplements in pregnant women in Colombia was found to be substantial. The variables significantly associated with their use were educational level, socioeconomic level, trimester of pregnancy, geographic level and ethnic group. These results indicate the necessity of implementing new health policies that guarantee uniform access to nutritional

Background The objective of this study is to report the costs of Chagas disease in Colombia, in terms of vector disease control programmes and the costs of providing care to chronic Chagas disease patients with cardiomyopathy. Methods Data were collected from Colombia in 2004. A retrospective review of costs for vector control programmes carried out in rural areas included 3,084 houses surveyed for infestation with triatomine bugs and 3,305 houses sprayed with insecticide. A total of 63 patient records from 3 different hospitals were selected for a retrospective review of resource use. Consensus methodology with local experts was used to estimate care seeking behaviour and to complement observed data on utilisation. Findings The mean cost per house per entomological survey was $4.4 (in US$ of 2004), whereas the mean cost of spraying a house with insecticide was $27. The main cost driver of spraying was the price of the insecticide, which varied greatly. Treatment of a chronic Chagas disease patient costs between $46.4 and $7,981 per year in Colombia, depending on severity and the level of care used. Combining cost and utilisation estimates the expected cost of treatment per patient-year is $1,028, whereas lifetime costs averaged $11,619 per patient. Chronic Chagas disease patients have limited access to healthcare, with an estimated 22% of patients never seeking care. Conclusion Chagas disease is a preventable condition that affects mostly poor populations living in rural areas. The mean costs of surveying houses for infestation and spraying infested houses were low in comparison to other studies and in line with treatment costs. Care seeking behaviour and the type of insurance affiliation seem to play a role in the facilities and type of care that patients use, thus raising concerns about equitable access to care. Preventing Chagas disease in Colombia would be cost-effective and could contribute to prevent inequalities in health and healthcare. PMID:19015725

Enhanced Orographic Tropical Rainfall: An Study of the Colombia's rainfall

Peñaranda, V. M.; Hoyos Ortiz, C. D.; Mesa, O. J.

2015-12-01

Convection in tropical regions may be enhanced by orographic barriers. The orographic enhancement is an intensification of rain rates caused by the forced lifting of air over a mountainous structure. Orographic heavy rainfall events, occasionally, comes along by flooding, debris flow and substantial amount of looses, either economics or human lives. Most of the heavy convective rainfall events, occurred in Colombia, have left a lot of victims and material damages by flash flooding. An urgent action is required by either scientific communities or society, helping to find preventive solutions against these kind of events. Various scientific literature reports address the feedback process between the convection and the local orographic structures. The orographic enhancement could arise by several physical mechanism: precipitation transport on leeward side, convection triggered by the forcing of air over topography, the seeder-feeder mechanism, among others. The identification of the physical mechanisms for orographic enhancement of rainfall has not been studied over Colombia. As far as we know, orographic convective tropical rainfall is just the main factor for the altitudinal belt of maximum precipitation, but the lack of detailed hydro-meteorological measurements have precluded a complete understanding of the tropical rainfall in Colombia and its complex terrain. The emergence of the multifractal theory for rainfall has opened a field of research which builds a framework for parsimonious modeling of physical process. Studies about the scaling behavior of orographic rainfall have found some modulating functions between the rainfall intensity probability distribution and the terrain elevation. The overall objective is to advance in the understanding of the orographic influence over the Colombian tropical rainfall based on observations and scaling-analysis techniques. We use rainfall maps, weather radars scans and ground-based rainfall data. The research strategy is

Martinez, Efrain; Duque, Patricia; Wolff, Marta

2007-03-02

The minimum postmortem interval can be estimated based on knowledge of the pattern of insect succession on a corpse. To use this approach requires that we take into account the rates of insect development associated with particular climatological conditions of the region. This study is the first to look at insect succession on decomposing carcasses in the high altitude plains (Paramo) in Colombia, at 3035 m above sea level. Five stages of decomposition were designated with indicator species identified for each stage: Callíphora nigribasis at the fresh stage; Compsomyiops verena at the bloated stage; Compsomyiops boliviana during active decay; Stearibia nigriceps and Hydrotaea sp. during advanced decay and Leptocera sp. for dry remains. A succession table is presented for carrion-associated species of the region, which can be used for estimating time since death in similar areas. Compsomyiops boliviana is reported for the first time in Colombia.

Bombus atratus bumblebees from Colombia that were caught in the wild and from breeding programs were screened for a broad set of bee pathogens. We discovered for the first time Lake Sinai Virus and confirmed the infection by other common viruses. The prevalence of Apicystis bombi, Crithidia bombi and Nosema ceranae was remarkably high. According to other studies the former two could have been co-introduced in South America with exotic bumble bees as Bombus terrestris or Bombus ruderatus. Given the fact that none of these species occur in Colombia, our data puts a new light on the spread of these pathogens over the South American continent. Copyright © 2015 The Authors.

A dengue fever surveillance study was conducted at three medical facilities located in the low-income district of San Javier in Medellin, Colombia. During March 2008 to 2009, 781 patients with fever regardless of chief complaint were recruited for acute dengue virus infection testing. Of the 781 tested, 73 (9.3%) were positive for dengue infection. Serotypes DENV-2 (77%) and -3 (23%) were detected by PCR. One patient met the diagnostic criteria for dengue hemorrhagic fever. Only 3 out of 73 (4.1%) febrile subjects testing positive for dengue infection were diagnosed with dengue fever by the treating physician. This study confirms dengue virus as an important cause of acute febrile illness in Medellin, Colombia, but it is difficult to diagnose without dengue diagnostic testing. PMID:24987421

Mitochondrial DNA (mtDNA) haplogroups in 1526 unrelated individuals from 11 Departments of Colombia

2013-01-01

The frequencies of four mitochondrial Native American DNA haplogroups were determined in 1526 unrelated individuals from 11 Departments of Colombia and compared to the frequencies previously obtained for Amerindian and Afro-Colombian populations. Amerindian mtDNA haplogroups ranged from 74% to 97%. The lowest frequencies were found in Departments on the Caribbean coast and in the Pacific region, where the frequency of Afro-Colombians is higher, while the highest mtDNA Amerindian haplogroup frequencies were found in Departments that historically have a strong Amerindian heritage. Interestingly, all four mtDNA haplogroups were found in all Departments, in contrast to the complete absence of haplogroup D and high frequencies of haplogroup A in Amerindian populations in the Caribbean region of Colombia. Our results indicate that all four Native American mtDNA haplogroups were widely distributed in Colombia at the time of the Spanish conquest. PMID:24130438

Knowledge, attitudes and practices of malaria in Colombia

PubMed Central

2014-01-01

Background Although Colombia has witnessed an important decrease in malaria transmission, the disease remains a public health problem with an estimated ~10 million people currently living in areas with malaria risk and ~61,000 cases reported in 2012. This study aimed to determine and compare the level of knowledge, attitudes and practices (KAP) about malaria in three endemic communities of Colombia to provide the knowledge framework for development of new intervention strategies for malaria elimination. Methods A cross-sectional KAP survey was conducted in the municipalities of Tierralta, Buenaventura and Tumaco, categorized according to high risk (HR) and moderate risk (MR) based on the annual parasite index (API). Surveys were managed using REDCap and analysed using MATLAB and GraphPad Prism. Results A total of 267 residents, mostly women (74%) were surveyed. Although no differences were observed on the knowledge of classical malaria symptoms between HR and MR regions, significant differences were found in knowledge and attitudes about transmission mechanisms, anti-malarial use and malaria diagnosis. Most responders in both regions (93.5% in MR, and 94.3% in HR areas) indicated use of insecticide-treated nets (ITNs) to protect themselves from malaria, and 75.5% of responders in HR indicated they did nothing to prevent malaria transmission outdoors. Despite a high level of knowledge in the study regions, significant gaps persisted relating to practices. Self-medication and poor adherence to treatment, as well as lack of both indoor and outdoor vector control measures, were significantly associated with higher malaria risk. Conclusions Although significant efforts are currently being made by the Ministry of Health to use community education as one of the main components of the control strategy, these generic education programmes may not be applicable to all endemic regions of Colombia given the substantial geographic, ethnic and cultural diversity.

Humanitarian IED clearance in Colombia

Hendrickx, J. M. H.; Molina, A.; Diaz, D.; Grasmueck, M.; Moreno, H. A.; Hernández, R. D.

2008-04-01

The development of Improvised Explosive Devices (IED's) by insurgents in Colombia is characterized by a quick response to counter IED measures. Many current IED's do not contain any metal parts and can have any shape or form. Due to the low metal content or the absence of any metal parts, sensors based on metal detection are not useful anymore. Due to the wide variety of sizes, shapes, and enclosure materials of current IED's, one and two-dimensional GPR sensors using a "library" of known shapes as well as acoustic sensors using material characteristic frequencies have become ineffective. Therefore, the Colombian experience strongly suggests that chemical sensors are the way for IED detection in soils since they do not depend on IED metal content, size, or shape but only on the presence of explosives, a necessary ingredient for any IED. Promising recently developed chemical sensors make use of semiconducting organic polymers (SOPs) such as FIDO and laser-induced breakdown spectroscopy (LIBS). Once an explosive has been detected, the IED needs to be identified and located. Therefore, there is a need for three-dimensional high resolution scans for identification of all subsoil features including rocks, roots, and IED's. The recently developed 3D-GPR (Ground Penetrating Radar) can map all features of the subsoil with a spatial resolution of about 2 cm or less. The objectives of this contribution are to inform about the IED problem in Colombia and how novel technologies may contribute to humanitarian IED clearance under humid tropical conditions.

The Atlas Lingüístico y Etnográfico de Colombia (Linguistic and Ethnographic Atlas of Colombia), known by "ALEC" is a compilation of popular speaking Spanish of the populations of Colombia; such research was carried out for more than fifty years. The result of this work is a collection of thematic maps organized in six volumes and its supplements in analog format. In that sense was created the project entitles "Interactive ALEC" which main objective is to develop a digital and interactive web version of the ethnographic and Linguistic Atlas of Colombia (1983) and its supplements. In this way the Corpus linguistics research group belonging to the Institute Caro y Cuervo and the research group NIDE of the Universidad Distrital "Francisco José de Caldas" have been working together in the design and development of the Atlas Web, that allows the visualization and consulting of the spatial information contained in the volume III of the analog ALEC Atlas, applying concepts of Geographical Information Systems and web cartography. Therefore, the objective of this paper is to show the process of design and development of the web prototype of the ALEC as a collection of static and dynamic maps, which show spatial information, combined with multimedia content, taking into account that in addition to all maps, the total compendium includes images, illustrations, photographs, audio and text comments. Likewise, the interactive ALEC is a good example of how to use geo-technology tools nowadays, because they are essential for the dissemination of geo linguistic information through internet, achieving more access and distribution of the Atlas web.

2014-08-01

Hantavirus pulmonary syndrome (HPS) is an often fatal rodent-borne zoonosis caused by any of at least 20 hantavirus genotypes distributed throughout the Americas. Although HPS has been documented in several bordering countries, it has not been reported in Colombia. Here we report seroconversion to a hantavirus in paired samples from a hospitalized patient with symptoms compatible with HPS from Montería, Córdoba Department, north-western Colombia. Tests for regionally endemic agents including Plasmodium, Leptospira, Salmonella, dengue virus, Brucella, Rickettsia, human immunodeficiency virus and hepatitis viruses were negative. Because the patient was enrolled in a clinical trial for hemorrhagic fevers conducted by the University of Córdoba, serum samples were collected on admission and at discharge. Testing using Sin Nombre virus ELISA showed IgG and IgM seroconversion between samples. The eventual finding of this first clinical case of hantavirus infection in Colombia is consistent with the high prevalence of hantavirus antibodies in humans in the region and the likely exposure of the patient to rodents. The clinical presentation was similar to that found in neighbouring Panama. Copyright © 2014 The Authors. Published by Elsevier Ltd.. All rights reserved.

To explore the variation in the spatial distribution of notified dengue cases in Colombia from January 2007 to December 2010 and examine associations between the disease and selected environmental risk factors. Data on the number of notified dengue cases in Colombia were obtained from the National Institute of Health (Instituto Nacional de Salud - INS) for the period 1 January 2007 through 31 December 2010. Data on environmental factors were collected from the Worldclim website. A Bayesian spatio-temporal conditional autoregressive model was used to quantify the relationship between monthly dengue cases and temperature, precipitation and elevation. Monthly dengue counts decreased by 18% (95% credible interval (CrI): 17-19%) in 2008 and increased by 30% (95% CrI: 28-31%) and 326% (95% CrI: 322-331%) in 2009 and 2010, respectively, compared to 2007. Additionally, there was a significant, nonlinear effect of monthly average precipitation. The results highlight the role of environmental risk factors in determining the spatial of dengue and show how these factors can be used to develop and refine preventive approaches for dengue in Colombia. © 2014 John Wiley & Sons Ltd.

2015-01-01

A systematic literature review was conducted to describe the epidemiology of dengue disease in Colombia. Searches of published literature in epidemiological studies of dengue disease encompassing the terms “dengue”, “epidemiology,” and “Colombia” were conducted. Studies in English or Spanish published between 1 January 2000 and 23 February 2012 were included. The searches identified 225 relevant citations, 30 of which fulfilled the inclusion criteria defined in the review protocol. The epidemiology of dengue disease in Colombia was characterized by a stable “baseline” annual number of dengue fever cases, with major outbreaks in 2001–2003 and 2010. The geographical spread of dengue disease cases showed a steady increase, with most of the country affected by the 2010 outbreak. The majority of dengue disease recorded during the review period was among those <15 years of age. Gaps identified in epidemiological knowledge regarding dengue disease in Colombia may provide several avenues for future research, namely studies of asymptomatic dengue virus infection, primary versus secondary infections, and under-reporting of the disease. Improved understanding of the factors that determine disease expression and enable improvement in disease control and management is also important. PMID:25790245

Objective. To describe the design of the SABE Colombia study. The major health study of the old people in Latin America and the Caribbean (LAC) is the Survey on Health, Well-Being, and Aging in LAC, SABE (from initials in Spanish: SAlud, Bienestar & Envejecimiento). Methods. The SABE Colombia is a population-based cross-sectional study on health, aging, and well-being of elderly individuals aged at least 60 years focusing attention on social determinants of health inequities. Methods and design were similar to original LAC SABE. The total sample size of the study at the urban and rural research sites (244 municipalities) was 23.694 elderly Colombians representative of the total population. The study had three components: (1) a questionnaire covering active aging determinants including anthropometry, blood pressure measurement, physical function, and biochemical and hematological measures; (2) a subsample survey among family caregivers; (3) a qualitative study with gender and cultural perspectives of quality of life to understand different dimensions of people meanings. Conclusions. The SABE Colombia is a comprehensive, multidisciplinary study of the elderly with respect to active aging determinants. The results of this study are intended to inform public policies aimed at tackling health inequalities for the aging society in Colombia. PMID:27956896

Camacho, Angela

2015-03-01

Physics in Colombia started to develop in the 70's as a research part of basic sciences with the acquisition, at that time, of large research equipments such as x-rays and EPR. Experimental work was soon supplemented by theoretical investigations, which led to the formation of research groups in condensed matter. In the early 80's existed such groups in five universities. In this report we present, after a short history of the main steps that guided the initial research subjects, the major areas already developed and the minor research groups that are in the stage of consolidation. Currently this type of work is done at least in 20 universities. We also show the actual numbers of researchers, publications, PhD students and laboratories discriminated in gender to complete an overview of Condensed Matter Physics in Colombia. Finally, we present a short review of the main theoretical issues that have been worked in the last decade focusing on low dimensional systems, their structural and optical properties

The sexual and reproductive rights of internally displaced women: the embodiment of Colombia's crisis.

Alzate, Mónica M

2008-03-01

As of 30 June 2006, more than 3.5 million Colombians are internally displaced persons (IDPs), the second largest IDP population in the world after that of Sudan. While most IDP studies treat the plight of internally displaced women (IDW) as an isolated phenomenon, this paper demonstrates that their situation reflects Colombia's chronic cultural, political and socio-economic crisis. This paper uses a sexual and reproductive rights framework to establish a connection between IDW and Colombia's culture of violence, discrimination and inequality. The effects of this culture of violence, discrimination and inequality are highlighted during a discussion of the rights to health, reproduction, privacy, physical integrity, education, and freedom from violence and sexual exploitation. This paper argues that a holistic understanding of Colombia's humanitarian emergency is essential to improving the lives of IDPs. It ends with some concrete, short-term recommendations to meet some of the needs of IDPs and other vulnerable populations.

The correct identification of the Anopheles species of the subgenus Nyssorhynchus is important because this subgenus includes the main malaria vectors in Colombia. This information is necessary for focusing a malaria control program. Geometric morphometrics were used to evaluate morphometric variation of 11 species of subgenus Nyssorhynchus present in Colombia and to distinguish females of each species. Materials and methods. The specimens were obtained from series and family broods from females collected with protected human hosts as attractants. The field collected specimens and their progeny were identified at each of the associated stages by conventional keys. For some species, wild females were used. Landmarks were selected on wings from digital pictures from 336 individuals, and digitized with coordinates. The coordinate matrix was processed by generalized Procrustes analysis which generated size and shape variables, free of non-biological variation. Size and shape variables were analyzed by univariate and multivariate statistics. The subdivision of subgenus Nyssorhynchus in sections is not correlated with wing shape. Discriminant analyses correctly classified 97% of females in the section Albimanus and 86% in the section Argyritarsis. In addition, these methodologies allowed the correct identification of 3 sympatric species from Putumayo which have been difficult to identify in the adult female stage. The geometric morphometrics were demonstrated to be a very useful tool as an adjunct to taxonomy of females the use of this method is recommended in studies of the subgenus Nyssorhynchus in Colombia.

Anopheles darlingi is an important vector of Plasmodium spp. in several malaria-endemic regions of Colombia. This study was conducted to test genetic variation of An. darlingi at a microgeographic scale (approximately 100 km) from localities in Córdoba and Antioquia states, in western Colombia, to better understand the potential contribution of population genetics to local malaria control programs. Microsatellite loci: nuclear white and cytochrome oxidase subunit I (COI) gene sequences were analyzed. The northern white gene lineage was exclusively distributed in Córdoba and Antioquia and shared COI haplotypes were highly represented in mosquitoes from both states. COI analyses showed these An. darlingi are genetically closer to Central American populations than southern South American populations. Overall microsatellites and COI analysis showed low to moderate genetic differentiation among populations in northwestern Colombia. Given the existence of high gene flow between An. darlingi populations of Córdoba and Antioquia, integrated vector control strategies could be developed in this region of Colombia. PMID:20595475

A recent report has shown that the phylogenetic origin of Helicobacter pylori based on multi-locus sequence typing (MLST) was significantly associated with the severity of gastritis in Colombia. However, the potential relationship between phylogenetic origin and clinical outcomes was not examined in that study. If the phylogenetic origin rather than virulence factors were truly associated with clinical outcomes, identifying a population at high risk for gastric cancer in Colombia would be relatively straightforward. In this study, we examined the phylogenetic origins of strains from gastric cancer and duodenal ulcer patients living in Bogota, Colombia. We included 35 gastric cancer patients and 31 duodenal ulcer patients, which are considered the variant outcomes. The genotypes of cagA and vacA were determined by polymerase chain reaction. The genealogy of these Colombian strains was analyzed by MLST. Bacterial population structure was analyzed using STRUCTURE software. H. pylori strains from gastric cancer and duodenal ulcer patients were scattered in the phylogenetic tree; thus, we did not detect any difference in phylogenetic distribution between gastric cancer and duodenal ulcer strains in the hpEurope group in Colombia. Sixty-six strains, with one exception, were classified as hpEurope irrespective of the cagA and vacA genotypes, and type of disease. STRUCTURE analysis revealed that Colombian hpEurope strains have a phylogenetic connection to Spanish strains. Our study showed that a phylogeographic origin determined by MLST was insufficient for distinguishing between gastric cancer and duodenal ulcer risk among hpEurope strains in the Andean region in Colombia. Our analysis also suggests that hpEurope strains in Colombia were primarily introduced by Spanish immigrants.

Madera, C A; Peña, M R; Mara, D D

2002-01-01

This paper discusses the applicability of effluent reuse in agriculture after treatment in a series of anaerobic, facultative and maturation ponds. The WSP system is located in Ginebra municipality, a small town in southwest Colombia. The total HRT is 12 days. Several samples of the final effluent were taken over a 55 day period and were analysed for E. coli, Streptococcus spp. and helminth eggs. Some additional grab samples were taken to determine the presence of pathogenic bacteria such as Salmonella spp. and Shigella spp. The results showed that the system was able to remove 4 log units of E. coli, 1 log unit of Streptococcus spp. and 100% of helminth eggs. Meanwhile, Salmonella spp. were detected in the effluent of the facultative pond whilst Shigella spp. were not detected in any sample. The main species of helminth eggs encountered were Taenia spp., Ascaris spp., Trichuris spp., Hymenolepis nana, H. diminuta and Enterobius vermicularis. Removal efficiencies were satisfactory despite the relatively short HRT. Nevertheless, WHO guidelines were slightly surpassed in the case of E. coli for unrestricted irrigation. The helminth egg value was always below the maximum WHO limit. Hence, this effluent can be safely used for restricted irrigation provided that field workers are protected from direct contact with wastewater given the presence of Salmonella spp. in the facultative pond effluent.

Influence of ENSO Modoki on Colombia Precipitation

2015-12-01

In recent years, multiple observations reported contrasting effects in climate patterns around the world, due to differential warming patterns in tropical regions of Pacific Ocean during ENSO warm and cold events. Several authors have proposedthe concept that these variations are part of a new type of El Niño-Southern Oscillation (ENSO) named as "Modoki". Using the classification of periods as Canonical or Modoki ENSO proposed by Tedeschi et al. (2013) we discriminatedthe quarterly mean values of precipitation in Colombia since 1975 to 2006 in order to analyze the rainfall behavior during El Niño Modoki (ENM) and La Nina Modoki (LNM), and contrast them with Canonical El Niño and La Niña (ENC-LNC) effects. The observations show that for the precipitation in Colombia, ENSO Modoki effects are different from Canonical ENSO effects, producing in general opposite climatic conditions between ENC and ENM, as well as between LNC and LNM. In other regions, the ENSO Modoki produces anomalies with the same sign that ENC, but with lower intensity. R. G. Tedeschi, I. F. Cavalcanti, and A. M. Grimm.

Phytophthora infestans, the causal agent of late blight in crops of the Solanaceae family, is one of the most important plant pathogens in Colombia. Not only are Solanum lycopersicum, and S. tuberosum at risk, but also several other solanaceous hosts (Physalis peruviana, S. betaceum, S. phureja, and S. quitoense) that have recently gained importance as new crops in Colombia may be at risk. Because little is known about the population structure of Phytophthora infestans in Colombia, we report here the phenotypic and molecular characterization of 97 isolates collected from these six different solanaceous plants in Colombia. All the isolates were analyzed for mating type, mitochondrial haplotypes, genotype for several microsatellites, and sequence of the internal transcribed spacer (ITS) region. This characterization identified a single individual of A2 mating type (from Physalis peruviana) for the first time in Colombia. All isolates had an ITS sequence that was at least 97% identical to the consensus sequence. Of the 97 isolates, 96 were mitochondrial haplotype IIa, with the single A2 isolate being Ia. All isolates were invariant for the microsatellites. Additionally, isolates collected from S. tuberosum and P. peruviana (64 isolates) were tested for: aggressiveness on both hosts, genotype for the isozymes (glucose-6-phosphate isomerase and peptidase), and restriction fragment length polymorphism fingerprint pattern as detected by RG57. Isolates from S. tuberosum were preferentially pathogenic on S. tuberosum, and isolates from P. peruviana were preferentially pathogenic on P. peruviana. The population from these two hosts was dominated by a single clonal lineage (59 of 64 individuals assayed), previously identified from Ecuador and Peru as EC-1. This lineage was mating type A1, IIa for mitochondrial DNA, invariant for two microsatellites, and invariant for both isozymes. The remaining four A1 isolates were in lineages very closely related to EC-1 (named EC-1.1, CO

Guillain-Barré syndrome (GBS) is a rapid-onset muscle weakness disease caused by the immune-mediated damage of the peripheral nervous system. Since there is an increase incidence of GBS cases in Latin America, particularly in Colombia, and most of them are currently preceded by Zika virus (ZIKV) infection, we aimed to assess the available evidence of the disease in Colombia through a systematic literature review. Out of 51 screened abstracts, only 16 corresponded to articles that met inclusion criteria, of which 15 were case reports or case series. A total of 796 cases of GBS were reported in the included articles. The majority of patients were males (66.8 %) and younger than 50 years old (94 %). An infectious disease before the onset of GBS was registered in 31 % of patients, with gastrointestinal or respiratory symptoms being the most frequently observed. In those cases in which electrodiagnostic tests were performed, the most common subphenotype was acute inflammatory demyelinating polyneuropathy (17 %). Death was reported in 15 % of patients. Data regarding GBS in Colombia is scant and heterogeneous. Taking into account the burden of the disease and the recent rise of GBS cases associated with ZIKV, a careful patient evaluation and a systematic collection of data are warranted. A form to data gathering is proposed.

The emerging vector of Chagas disease, Triatoma maculata (Hemiptera, Reduviidae), is one of the most widely distributed Triatoma species in northern South America. Despite its increasing relevance as a vector, no consistent picture of the magnitude of genetic and phenetic diversity has yet been developed. Here, several populations of T. maculata from eleven Colombia and Venezuela localities were analyzed based on the morphometry of wings and the mitochondrial NADH dehydrogenase subunit 4 (ND4) gene sequences. Our results showed clear morphometric and genetic differences among Colombian and Venezuelan populations, indicating high intraspecific diversity. Inter-population divergence is suggested related to East Cordillera in Colombia. Analyses of other populations from Colombia, Venezuela, and Brazil from distinct eco-geographic regions are still needed to understand its systematics and phylogeography as well as its actual role as a vector of Chagas disease. © 2016 The Society for Vector Ecology.

Pentodontini is the most diverse tribe of Dynastinae (Coleoptera: Scarabaeidae), and most of the genera are restricted to a single biogeographic region. In this work, the taxonomic composition of the Pentodontini in Colombia was determined, and genera and species were diagnosed based on external morphology and male genitalia. Records of 1,580 specimens from 31 departments and 398 localities in Colombia were obtained from 24 species in the genera Bothynus Hope, Denhezia Dechambre, Euetheola Bates, Hylobothynus Ohaus, Oxyligyrus Arrow, Parapucaya Prell, Pucaya Ohaus, and Tomarus Erichson. Oxyligyrus cayennensis Endrödi, Tomarus cicatricosus (Prell), and T. pullus (Prell) are reported for the first time from Colombia. Pucaya punctata Endrödi is reduced to synonymy with Pucaya pulchra Arrow. Possible changes in the classification of Denhezia Dechambre are discussed. Dichotomous keys are provided for Colombian genera and species. Taxonomic descriptions and distribution maps are included for all species.

Colombia is a country of diverse geographic regions, some with mountainous terrain that can make access to urban areas difficult for individuals who live in remote areas. In 2005, a program was initiated to establish remote peritoneal dialysis (PD) centers in Colombia to improve access to PD for patients with end-stage renal disease who face geographic or financial access barriers. The present study was a multi-center cohort observational study of prevalent home PD patients who were at least 18 years of age and were being managed by one of nine established remote PD centers in Colombia over a 2-year period. Data were collected from clinical records, databases, and patient interviews. Patient survival, incidence of peritonitis, and rate of withdrawal from PD therapy were assessed. A total of 345 patients were eligible for the study. The majority (87.8%) of patients lived on one to two times a minimum monthly salary (equivalent to US$243 - US$486). On average, patients traveled 1.2 hours and 4.3 hours from their home to their remote PD center or an urban reference renal clinic, respectively. The incidence rate of peritonitis was 2.54 episodes per 100 patient-months of therapy. A bivariate analysis showed a significantly higher risk of peritonitis in patients who were living on less than one times a monthly minimum salary (p < 0.05) or who had a dirt, cement, or unfinished wood floor (p < 0.05). The 1-year and 2-year patient survival rates were 92.44% and 81.55%, respectively. The 1-year and 2-year technique survival rates were 97.27% and 89.78%, respectively. With the support of remote PD centers that mitigate geographic and financial barriers to healthcare, home PD therapy is a safe and appropriate treatment option for patients who live in remote areas in Colombia.

A systematic review of telemedicine projects in Colombia was conducted. We searched electronic databases, and also searched for relevant Internet websites. Each project manager was contacted by telephone to identify projects which had not actually been carried out. They were interviewed to request information about the projects they were managing, and whether they knew of other projects in Colombia. The search process identified 43 different projects, which were classified into two groups: telemedicine research initiatives and projects for providing health-care services via telemedicine. There were 32 projects which provided telemedicine services, of which 14 had been finished, 11 remained active, 4 were being implemented and no data were available about the state of the other 3. Health-care services had been provided using telemedicine to at least 550,000 patients. The projects had connected more than 650 health-care institutions, mainly in deprived areas of the country. Unfortunately, although many projects seem to have had a positive effect, none of them had been rigorously evaluated, and therefore in the absence of scientific evidence no general recommendations can be made. However, the methodology of the present study appears suitable for similar reviews of telemedicine in other developing countries.

[Colombia: what has happened with its health reform?].

PubMed

Gómez-Arias, Rubén Darío; Nieto, Emmanuel

2014-01-01

The health reform adopted in Colombia in 1993 was promoted by different agencies as the model to follow in matters of health policy. Following the guidelines of the Washington Consensus and the World Bank, the Government of Colombia, with the support of national political and economic elites, reorganized the management of health services based on market principles, dismantled the state system, increased finances of the sector, assigned the management of the system to the private sector, segmented the provision of services, and promoted interaction of actors in a competitive scheme of low regulation. After 20 years of implementation, the Colombian model shows serious flaws and is an object of controversy. The Government has weakened as the governing entity for health; private groups that manage the resources were established as strong centers of economic and political power; and violations of the right to health increased. Additionally, corruption and service cost overruns have put a strain on the sustainability of the system, and the state network is in danger of closing. Despite its loss of prestige at the internal level, various actors within and outside the country tend to keep the model based on contextual reforms.

Mud Flow - Slow and Fast

NASA Astrophysics Data System (ADS)

Mei, C. C.; Liu, K.-F.; Yuhi, M.

Heavy and persistent rainfalls in mountainous areas can loosen the hillslope and induce mud flows which can move stones, boulders and even trees, with destructive power on their path. In China where 70% of the land surface is covered by mountains, debris flows due to landslides or rainfalls affect over 18.6% of the nation. Over 10,000 debris flow ravines have been identified; hundreds of lives are lost every year [1]. While accurate assessment is still pending, mud flows caused by Hurr icane Mitch in 1998 have incurred devastating floods in Central America. In Honduras alone more than 6000 people perished. Half of the nation's infrastructures were damaged. Mud flows can also be the result of volcanic eruption. Near the volcano, lava and pyroclastic flows dominate. Further downstream solid particles become smaller and can mix with river or lake water, rainfall, melting snow or ice, or eroded soil, resulting in hyperconcentrated mud mixed with rocks. The muddy debris can travel at high speeds over tens of miles down the hill slopes and devastate entire communities. In 1985 the catastrophic eruption of Nevado del Ruiz in Colombia resulted in mud flows which took the life of 23,000 inhabitants in the town of Amero [2]. During the eruption of Mt. Pinatubo in Phillipnes in 1991, one cubic mile of volcanic ash and rock fragments fell on the mountain slopes. Seasonal rain in the following months washed down much of the loose deposits, causing damage to 100,000 villages. These catastrophes have been vividly recorded in the film documentary by Lyons [3].

This paper summarizes prevalence of Toxoplasma gondii in humans and animals and associated correlates of infection, clinical spectrum of disease in humans, and genetic diversity of T. gondii isolates from Colombia. Recent studies, especially in the states of Antioquia, Quindío and Cundinamarca, indicate that toxoplasmosis is a major public health problem. Approximately half of the women of child bearing age have T. gondii antibodies, and the clinical disease in congenitally infected children is more severe than in Europe. Limited studies indicate that the strains of T. gondii from Colombia are genetically and phenotypically different than in Europe and North America. However, epidemiological factors, such as the involvement of domestic and/or wild animals in transmission, the distribution of strain diversity by natural geographic regions, and the variation in risk factors between regions that are associated with human infection in Colombia, remain unknown. Areas of research for the future are outlined. This review should be of interest to biologists, veterinarians, physicians, and parasitologists.

From War on Drugs to War against Terrorism: modeling the evolution of Colombia's counter-insurgency.

Strategic and tactical planning for military intervention needs revision as the causes, methods, and means of conflict have evolved. Counter-insurgent engagement is one such intervention that governments, militaries, and non-governmental organizations seek to better understand. Modeling insurgencies is an acceptable means to gain insight into the various characteristics of asymmetric warfare to proffer prescriptive resolutions for mitigating their effects. Colombia's insurgency poses the challenge of assessing population behavior in a non-traditional revolutionary climate. Factors prevalent in traditional insurgency are not applicable in Colombia, specifically between the years 1993 and 2001 with the democratization of the drug cartels. The catastrophic events of September 11th reverberated in Colombia resulting in a new policy and strategy to the waging the counter-insurgency there. This research introduces a structured methodology to modeling the Colombian counter-insurgency incorporating qualitative assessment, mathematical representation, and a System Dynamics approach to represent the effects of the policy change.

Anopheles triannulatus s.l. is a species complex, however in Colombia its taxonomic status is unclear. This study was conducted to understand the level of genetic differentiation or population structure of specimens of An. triannulatus s.l. from northwestern and southeastern Colombia. Cytochrome oxidase subunit I (COI) and internal transcribed spacer (ITS2) sequence analyses suggested high genetic differentiation between the NW and SE populations. A TCS network and Bayesian inference analysis based on 814 bp of COI showed two main groups: group I included samples from the NW and group II samples from the SE. Two main ITS2-polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) patterns were found. Pattern I is present in both the NW and SE, and pattern II is found in the SE specimens. To further elucidate the taxonomic status of An. triannulatus s.l. in Colombia and how these COI lineages are related to the Triannulatus Complex species, the evaluation of immature stages, male genitalia, and additional mitochondrial and nuclear markers will be needed.

To describe the time trends of the incidence and mortality rates of oral cancer (OC) in Cali, Colombia between 1962-2007. Age-standardized (Segi's world population) incidence (ASIR) and mortality (ASMR) rates for oral cancer were estimated using data from the Population-based Cancer Registry of Cali, Colombia and from the database of the Municipal Secretary of Public Health (MSPH) respectively. Annual percentage change (APC) was used to measure the changes in rates over time. 1637 new cases of oral cancer were registered in the CPCR and the mean age upon diagnosis was 60 years. The ASIR decreased from 1962-2007 in men APC= 1.3 (IC95%:-2.0; -0.6) and women APC= -1.0 (IC95%: -1.7; -0.4).The ASMR decreased from 1984-2001 only in men, APC=2.8 (IC95%: -4.1; -1.5). There was a significant decrease in the incidence and mortality rates for OC in Cali, Colombia. The type of tumor associated to these changes was the squamous cell carcinoma.

Stroke is a primary cause of death and disability in upper-middle-income countries such as Colombia. Given the lack of comprehensive rehabilitation for stroke patients in Colombia, there is a need to assess longitudinal mental health problems poststroke in this region. To compare the course of mental health in stroke patients to healthy controls over the first year poststroke in Ibague, Colombia. Cross-sectional study. The Psychological Attention Center of Antonio Nariño University in Ibague, Colombia. Stroke patients (n = 50) and age- and gender-matched healthy controls (n = 50). Patients and controls completed self-report Spanish versions of demographic information, injury-related characteristics, and mental health questionnaires MAIN OUTCOME MEASUREMENTS: Outcomes assessed included mental health (depression, anxiety, and stress) at 3, 6, and 12 months poststroke. Hierarchical linear models suggested that stroke patients had worse depression and anxiety over time than controls (P < .001). Among patients, depression and anxiety decreased over time (P < .001), whereas stress increased over time (P < .01). The findings suggest that although anxiety and depression improved over time in stroke patients, their mental health remained significantly lower than that of controls. This is the first study to examine the course of mental health over the first year poststroke in Latin America, specifically in Ibague, Colombia. Despite the improvements in anxiety and depression over the first year poststroke, patient anxiety and depression were still worse in comparison to those in healthy controls. The current findings indicate a need for rehabilitation services in Colombia, especially targeting mental health issues. I. Copyright © 2017 American Academy of Physical Medicine and Rehabilitation.

For those confirmed Zika cases, there were nearly 20,000 (18.5%) suspected to be pregnant women, resulting in 157 confirmed cases of microcephaly in newborns reported by their health government agency. There is a clear under-estimation of the total number of cases and in addition no prior publications have been published to demonstrate the clinical aspects of the Zika infection in Colombia. We characterized one Zika presentation to be able to compare and contrast with other cases of Zika infection already reported in the literature. In this case report, we demonstrate congenital microcephaly at week 19 of gestation in a 34-year-old mother who showed symptoms compatible with Zika virus infection from Sincelejo, State of Sucre, in the Colombian Caribbean. Zika virus RNA was detected in the placenta using real-time reverse transcriptase polymerase chain reaction (RT-PCR). At week 25, the fetus weigh estimate was 770 g, had a cephalic perimeter of 20.2 cm (5th percentile), ventriculomegaly on the right side and dilatation of the fourth ventricle. At week 32, the microcephaly was confirmed with a cephalic perimeter of 22 cm, dilatation of the posterior atrium to 13 mm, an abnormally small cerebellum (29 mm), and an augmented cisterna magna. At birth (39 weeks by cesarean section), the head circumference was 27.5 cm, and computerized axial tomography (Siemens Corp, 32-slides) confirmed microcephaly with calcifications. We report a first case of maternal Zika virus infection associated with fetal microcephaly in Colombia and confirmed similar presentation to those observed previous in Brazil, 2015-2016.

Colombia an approach to create a national space agency

NASA Astrophysics Data System (ADS)

Arenales, O.

Space exploration is a great human adventure: culturally, scientifically, technologically and industrially. Since the earliest of times, civilizations have been united in their awe of, and inspiration by, the cosmos, as testified in particularly by the peoples and cultures of the Central and South American continent in pre- Columbian times. Today, space systems have become an essential tool for the scientific disciplines related to the knowledge of the universe, including our own planet and its close or its remote environment. The main objective of this research is to explain the way in which Colombia, rich in myths and secular legends connecting mankind to the universe, must in the present tackle the issue of its development of space activities. The context in which it could be carried out is also described, along with a perspective of the current state of science and technology in the space sector on a global scale. Any modern nation is concerned with its independence, whether political, economic, or intellectual. That is why we support the concept of countries in the process of development becoming actively involved in the international space scene. Indeed, having limitations in industrial and technological exchange, we feel excluded today from key fields for our tomorrow. This paper thus proposes to demonstrate how in a time that can be regarded as one of the most serious crises in its history, Colombia could, in an atmosphere free from fratricidal conflicts, exploit its space matter capabilities. We do not limit our focus to the scientific field, but also consider the social, economic and cultural aspects. The results of this research delineate how Colombia could start a new optimistic phas e of its development, joining the international space programs within the framework of agreements among the regional governments in Latin America.

The aim of this work was to detect and identify Rickettsia species in ticks collected in rural areas of Villeta, Colombia. Tick specimens were collected from domestic animals and walls of houses in five rural villages of Villeta town and from humans in Naranjal village (same town). Moreover, a flea collected from the same area was also processed. DNA was extracted and tested by conventional, semi-nested, and nested PCR reactions targeting rickettsial genes. In the ticks collected from humans from Naranjal village, a nymph of Amblyomma cajennense sensu lato was amplified using primers for ompA and sequenced (100% identity with "Candidatus Rickettsia amblyommii"). Last, three amplicons from the Ctenocephalides felis flea, corresponding to gltA, ompB, and 16S rRNA genes, showed high identity with R. felis (98.5%, 97.3%, and 99.2%, respectively) and "Candidatus Rickettsia asemboensis" (99.7% and 100%, respectively). To our knowledge, these results correspond to the first molecular detection in Colombia of "Candidatus Rickettsia amblyommii" and "Ca. Rickettsia asemboensis" in fleas.

Triatoma dimidiata is an important vector of Chagas disease in Central America and countries of northern South America. In Colombia, it has a wide geographical distribution with reported presence in 14 departments in the Andean, Caribbean, Eastern plains and Upper Magdalena regions, where it occupies different natural and artificial ecotopes. The species is considered a secondary vector in the transmission of Trypanosoma cruzi. Its presence in wild, peridomestic and intradomiciliary habitats in the Andean region, coupled with its ability to move between them, has allowed it to escape the control based on pyrethroids spraying, highlighting its importance in maintaining transmission of the parasite through the potential reinfestation of homes.Understanding the relation of T. dimidiata and its habitats, as well as the empowerment of communities, will contribute to the development of effective and lasting control systems.The purpose of this review was to describe the distribution, risk factors, ecology, entomological features and habitats of T. dimidiata populations in Colombia, and to propose alternative interventions in agreement with the specific characteristics of the species.

[Active euthanasia in Colombia and assisted suicide in California].

The institution of active euthanasia has been legal in Colombia since 2015. In California, the regulation on physician-assisted suicide will come into effect on January 1, 2016. The legal institution of active euthanasia is not accepted under the law of the United States of America, however, physician-assisted suicide is accepted in an increasing number of member states. The related regulation in Oregon is imitated in other member states. In South America, Colombia is not the first country to legalize active euthanasia: active euthanasia has been legal in Uruguay since 1932. The North American legal tradition markedly differs from the South American one and both are incompatible with the Central European rule of law. In Hungary and in most European Union countries, solely the passive form of euthanasia is legal. In the Benelux countries, the active form of euthanasia is legal because the supranational law of the European Union does not prohibit it. Notwithstanding, European Union law does not prescribe legalization of either the active form of euthanasia, or the physician-assisted suicide.

Security for whom? Stabilisation and civilian protection in Colombia.

Elhawary, Samir

2010-10-01

This paper focuses on three periods of stabilisation in Colombia: the Alliance for Progress (1961-73) that sought to stem the threat of communist revolution in Latin America; Plan Colombia and President Alvaro Uribe's 'democratic security' policy (2000-07) aimed at defeating the guerrillas and negotiating a settlement with the paramilitaries; and the current 'integrated approach', adopted from 2007, to consolidate more effectively the state's control of its territory.(1) The paper assesses the extent to which these stabilisation efforts have enhanced the protection of civilians and ultimately finds that in all three periods there has been a disconnect between the discourse and the practice of stabilisation. While they have all sought to enhance security, in actual fact, they have privileged the security of the state and its allies at the expense of the effective protection of the civilian population. This has not only led to widespread human rights abuses but also has undermined the long-term stability being pursued. © 2010 The Author(s).

2018-04-11

Reducing maternal mortality is a top priority in Latin American countries. Despite the progress in maternal mortality reduction, Brazil and Colombia still lag behind countries at similar levels of development. Using data from the Demographic Health Survey, this study quantified and compared, by means of concentration indices, the socioeconomic-related inequity in access to four key maternal health interventions in Brazil and Colombia. Decomposition analysis of the concentration index was used for two indicators - skilled attendance at birth and postnatal care in Brazil. Coverage levels of the four key maternal health interventions were similar in the two countries. More specifically, we found that coverage of some of the interventions (e.g. ante-natal care and skilled birth assistance) was higher than 90% in both countries. Nevertheless, the concentration index analysis pointed to significant pro-rich inequities in access in all four key interventions in both countries. Interestingly, the analysis showed that Colombia fared slightly better than Brazil in terms of equity in access of the interventions studied. Finally, the decomposition analysis for the presence of a skilled attendant at birth and postnatal care in Brazil underlined the significance of regional disparities, wealth inequalities, inequalities in access to private hospitals, and inequalities in access to private health insurance. There are persistent pro-rich inequities in access to four maternal health interventions in both Brazil and Colombia. The decomposition analysis conducted on Brazilian data suggests the existence of disparities in system capacity and quality of care between the private and the public health services, resulting in inequities of access to maternal health services.

TESTING MULTI-CRITERIA DECISION ANALYSIS FOR MORE TRANSPARENT RESOURCE-ALLOCATION DECISION MAKING IN COLOMBIA.

Castro Jaramillo, Hector Eduardo; Goetghebeur, Mireille; Moreno-Mattar, Ornella

2016-01-01

In 2012, Colombia experienced an important institutional transformation after the establishment of the Health Technology Assessment Institute (IETS), the disbandment of the Regulatory Commission for Health and the reassignment of reimbursement decision-making powers to the Ministry of Health and Social Protection (MoHSP). These dynamic changes provided the opportunity to test Multi-Criteria Decision Analysis (MCDA) for systematic and more transparent resource-allocation decision-making. During 2012 and 2013, the MCDA framework Evidence and Value: Impact on Decision Making (EVIDEM) was tested in Colombia. This consisted of a preparatory stage in which the investigators conducted literature searches and produced HTA reports for four interventions of interest, followed by a panel session with decision makers. This method was contrasted with a current approach used in Colombia for updating the publicly financed benefits package (POS), where narrative health technology assessment (HTA) reports are presented alongside comprehensive budget impact analyses (BIAs). Disease severity, size of population, and efficacy ranked at the top among fifteen preselected relevant criteria. MCDA estimates of technologies of interest ranged between 71 to 90 percent of maximum value. The ranking of technologies was sensitive to the methods used. Participants considered that a two-step approach including an MCDA template, complemented by a detailed BIA would be the best approach to assist decision-making in this context. Participants agreed that systematic priority setting should take place in Colombia. This work may serve as the basis to the MoHSP on its interest of setting up a systematic and more transparent process for resource-allocation decision-making.

Colombia, like many developing countries, has not committed resources to fight the AIDS problem. They have used the media for condom promotion and other sexually transmitted diseases. There have been 151 deaths caused by AIDS by the end of 1988; 344 cases are known, and 130 additional have tested positive to the virus. Health officials were reluctant to recognize the problem, thinking it was outside their country and that they would not be affected by it. Since then, they have tried to target high risk groups and educate them and assist with testing and counseling. There is a move to make the new drug zidovudine available, but few could afford its high price. The authorities have put transvestite prostitutes in jail and kept them for AIDS testing, but few woman prostitutes have been tested. Up until 1986, only 30% of the Red Cross blood bank supplies were being tested; now 80% are, although it comprises only about 40% of the total supply. Drugs are used heavily, but mostly smoked, in Colombia, yet there is some concern about increased use of needles. The majority of cases in Columbia have been homosexual and bisexual men, but prostitution among men and women is prevalent in large cities such as Bogota. Health officials state that education is the best deterrent, but must be perpetuated so people will be constantly reminded.

Contraceptive social marketing and community-based distribution systems in Colombia.

PubMed

Vernon, R; Ojeda, G; Townsend, M C

1988-01-01

Three operations research experiments were carried out in three provinces of Colombia to improve the cost-effectiveness of Profamilia's nonclinic-based programs. The experiments tested: (a) whether a contraceptive social marketing (CSM) strategy can replace a community-based distribution (CBD) program in a high contraceptive use area; (b) if wage incentives for salaried CBD instructors will increase contraceptive sales; and (c) whether a specially equipped information, education, and communication (IEC) team can replace a cadre of rural promoters to expand family planning coverage. All three strategies proved to be effective, but only the CSM system yielded a profit. Despite this, Profamilia discontinued its CSM program soon after the experiment was completed. Unexpected government controls regulating the price and sale of contraceptives in Colombia made the program unprofitable. As a result, family planning agencies are cautioned against replacing CBD programs with CSM. Instead, CBD programs might adopt a more commercial approach to become more efficient.

Analysing the fundamental methodological aspects which should be considered when drawing up calibration procedure for electro-medical equipment, thereby permitting international standard-based accreditation of electro-medical metrology laboratories in Colombia. NTC-ISO-IEC 17025:2005 and GTC-51-based procedures for calibrating electro-medical equipment were implemented and then used as patterns. The mathematical model for determining the estimated uncertainty value when calibrating electro-medical equipment for accreditation by the Electrical Variable Metrology Laboratory's Electro-medical Equipment Calibration Area accredited in compliance with Superintendence of Industry and Commerce Resolution 25771 May 26th 2009 consists of two equations depending on the case; they are: E = (Ai + sigmaAi) - (Ar + sigmaAr + deltaAr1) and E = (Ai + sigmaAi) - (Ar + sigmaA + deltaAr1). The mathematical modelling implemented for measuring uncertainty in the Universidad Tecnológica de Pereira's Electrical Variable Metrology Laboratory (Electro-medical Equipment Calibration Area) will become a good guide for calibration initiated in other laboratories in Colombia and Latin-America.

Bothrops punctatus (Chocoan forest lancehead) is a semi-arboreal pitviper species distributed in Panamá, Colombia, and Ecuador, whose human envenomation is poorly characterized. We describe two patients bitten by B. punctatus, whose most relevant clinical feature was the development of a severe coagulopathy with few local manifestations (mild edema without signs of necrosis) at the site of the bite. Patients quickly improved their clinical and laboratory abnormalities after polyvalent antivenom application. Copyright © 2016 Elsevier Ltd. All rights reserved.

NorTropical Warm Pool variability and its effects on the climate of Colombia

Much has been said about the effects of El Niño Southern Oscillation (ENSO) on oceanographic and climatic conditions in Colombia, but little is known about the influence of the Atlantic Warm Pool (AWP), which includes the gulf of Mexico, the Caribbean and the western tropical North Atlantic. The AWP has been identified by some authors as an area that influences the Earth's climate, associated with anomalous summer rainfall and hurricane activity in the Atlantic. The aim of this study was to understand the variation in the AWP and its effects on the climate of Colombia. An annual average of sea surface temperature (SST) was obtained from the composition of monthly images of the Spectroradiometer Moderate Resolution Imaging Spectroradiometer (MODIS), with resolution of 4 km, for one area that comprises the marine territory of Colombia, Panama, Costa Rica both the Pacific and the Caribbean, and parts of the Caribbean coast of Nicaragua, for the period between 2007 and 2013. The results suggest that warm pool is not restricted to the Caribbean, but it also covers a strip Pacific bordering Central America and the northern part of the Colombian coast, so it should be called the Nor-Tropical Warm pool (NTWP). Within the NTWP higher SST correspond to a marine area extending about 1 degree north and south of Central and out of the Colombian Caribbean coast. The NTWP also showed large interannual variability, with the years 2008 and 2009 with lower SST in average, while 2010, 2011 and 2013 years with warmer conditions, matching with greater precipitation. It was also noted that during warmer conditions (high amplitude NTWP) the cold tongue from the south Pacific has less penetration on Colombian coast. Finally, the results suggest a strong influence of NTWP in climatic conditions in Colombia.

2007-09-01

The social environment is an important determinant of population and individual health. However, its impact is often not considered in national health policies and generally its attributes are considered as constants. For this reason, contemporary health policies place greater emphasis on individual risk factors. Colombias position in the world ranking is described with respect to several social macro-determinants of health, previously characterized as components of class/welfare regime model. The exploratory study included all countries with comparable data including the following: (1) economic development [gross domestic product per capita adjusted for purchasing power parity], (2) income inequality [Gini coefficient], (3) social capital corruption perceptions index and generalized trust, and (4) political regime index of freedom. First, correlations between these macro-determinants were estimated, and second, the relationship between them and life expectancy at birth was explored. Finally, the position of Colombia in global context was determined. Important correlations occurred among the macro-determinants. Colombia tended to have intermediate to low positions in the global context in all macro-determinants, with the exception of gross domestic product per capita adjusted for purchasing power parity. The macro-determinant of population health with the highest potential of effecting improvement in health conditions is to modify income inequality.

Young adults 18 to 25 years old show the highest prevalence of marijuana use in Latin America. This study analyzes the changes in prevalence of marijuana use among university students in the Andean Community (Bolivia, Colombia, Ecuador, and Peru) from two studies carried out in 2009 and in 2012. Data were collected through representative two-stage samples of universities and students in the Andean Community. An online survey was administered using a standardized questionnaire. Prevalence was calculated for lifetime, past year, and past month. Marijuana was the most widely used illicit substance consumed among university students, in 2009 and in 2012. Past month prevalence among university students in 2009 in Colombia was 5.27%, in Peru 1.00%, in Ecuador 1.68%, and in Bolivia 0.76%. Past month prevalence in 2012 in Colombia was 7.14%, in Ecuador 3.67%, in Peru 1.62%, and in Bolivia 1.45% in 2012. Among university students in the Andean Community, past month prevalence increased among both males and females between 2009 and 2012 in most countries. Marijuana continues to be the most commonly used illicit drug in Latin American countries. Increases in prevalence among young adults could have important implications for national drug policy.

To support the geodynamics research at the northwestern corner of South America, GEORED, the acronym for "Geodesia: Red de Estudios de Deformación" has been adopted for the Project "Implementation of the National GNSS Network for Geodynamics" carried out by the Colombian Geological Survey, (SGC), formerly INGEOMINAS. Beginning in 2007, discussions within the GEORED group led to a master plan for the distribution of the base permanent GPS/GNSS station array and specific areas of interest for campaign site construction. The use of previously identified active faults as preferred structures along which stresses are transferred through the deformational area led to the idea of segmentation of the North Andes within Colombia into 20 tectonic sub-blocks. Each of the 20 sub-blocks is expected to have, at least, three-four permanent GPS/GNSS stations within the block along with construction of campaign sites along the boundaries. Currently, the GEORED Network is managing 46 continuously including: 40 GEORED GPS/GNSS continuously operating stations; 4 GNSS continuously operating stations provided by the COCONet (Continuously Operating Caribbean GPS Observational Network) Project; the Bogotá IGS GPS station (BOGT), installed in 1994 under the agreement between JPL-NASA and the SGC; and the San Andres Island station, installed in 2007 under the MOU between UCAR and the SGC. In addition to the permanent installations, more than 230 GPS campaign sites have been constructed and are being occupied one time per year. The Authority of the Panama Canal and the Escuela Politecnica de Quito have also provided data of 4 and 5 GPS/GNSS stations respectively. The GPS data are processed using the GIPSY-OASIS II software, and the GPS time series of daily station positions give fundamental information for both regional and local geodynamics studies. Until now, we have obtained 100 quality vector velocities for Colombia, 23 of them as part of the permanent network. The GPS/GNSS stations

Suicides are one of the main public health issues globally. Objective: To analyze the trends and impact of suicide mortality in Colombia and México between 2000 and 2013, nationally, by sex and age groups. Materials and methods: Mortality vital statistics from the Colombian Departamento Administrativo Nacional de Estadística and the Mexican Instituto Nacional de Estadística y Geografía were used. We conducted a descriptive and cross sectional study for which we calculated standardized mortality rates and years of life lost in people between 0 and 100 years of age. Results: In Colombia, the suicide mortality rate decreased between 2000 and 2013 for both sexes (28% for men and 38% for women); an opposite trend was observed in México (with an increase of 34% for males and 67% for females). In 2013, the years of life lost in Colombia were 0,32 among men and 0,15 among women, with a decreasing trend since 2000, whereas in México a level of 0,42 was observed in men and 0,2 in women, with an increasing trend since 2000. The age groups where suicides had a bigger impact were those of men 15 to 49 years of age in both countries, while suicides were more uniformly distributed among women between 15 and 84 years of age.  Suicide mortality increased gradually in México, whereas in Colombia an opposite trend was observed. Suicides can be prevented, so it is fundamental to implement public health policies focused on timely identification, comprehensive prevention strategies and the study of associated risk factors.

Managing water scarcity in the Magdalena river basin in Colombia.An economic assessment

NASA Astrophysics Data System (ADS)

Bolivar Lobato, Martha Isabel; Schneider, Uwe A.

2014-05-01

Key words: global change, water scarcity, river basin In Colombia, serious water conflicts began to emerge with the economic development in the 70ies and 80ies and the term "water scarcity" became a common word in this tropical country. Despite a mean annual runoff of 1840 mm, which classifies Colombia as a water rich country, shortfalls in fresh water availability have become a frequent event in the last two decades. One reason for the manifestation of water scarcity is the long-held perception of invulnerable water abundance, which has delayed technical and political developments to use water more efficiently. The Magdalena watershed is the most important and complex area in Colombia, because of its huge anthropogenic present, economic development and increasing environmental problems. This river basin has a total area of 273,459 km2, equivalent to 24% of the territory of the country. It is home to 79% of the country's population (32.5 million of inhabitants) and approximately 85% of Gross Domestic Product of Colombia is generated in this area. Since the economic development of the 1970s and 1980s, large changes in land cover and related environmental conditions have occurred in the Magdalena basin. These changes include deforestation, agricultural land expansion, soil degradation, lower groundwater and increased water pollution. To assess the consequences of geophysical alteration and economic development, we perform an integrated analysis of water demand, water supply, land use changes and possible water management strategies. The main objective of this study is to determine how global and local changes affect the balance between water supply and demand in the Magdalena river basin in Colombia, the consequences of different water pricing schemes, and the social benefits of public or private investments into various water management infrastructures. To achieve this goal, a constrained welfare maximization model has been developed. The General Algebraic Modeling

Leishmaniases are tropical zoonotic diseases, caused by kinetoplastid parasites from the genus Leishmania. New World (NW) species are related to sylvatic cycles although urbanization processes have been reported in some South American Countries such as Colombia. Currently, few studies show the relative distribution of Leishmania species related to cutaneous Leishmaniasis (CL) in South America due to the lack of accurate surveillance and public health systems. Herein, we conducted a systematic estimation of the Leishmania species causing CL in Colombia from 1980 to 2001 via molecular typing and isoenzymes. A total of 327 Leishmania isolates from humans, sandflies and reservoirs were typed as L. panamensis 61.3% (201), L. braziliensis 27.1% (88), L. lainsoni 0.6% (2), L. guyanensis 0.9% (3), L. infantum chagasi 4% (12), L. equatoriensis 0.6% (2), L. mexicana 2.1% (8), L. amazonensis 2.8% (9) and L. colombiensis 0.6% (2). This is the first report of two new Leishmania species circulating in Colombia and suggests the need to convince the Colombian government about the need to deploy and standardize tools for the species identification to provide adequate management to individuals suffering this pathology.

Leishmaniases are tropical zoonotic diseases, caused by kinetoplastid parasites from the genus Leishmania. New World (NW) species are related to sylvatic cycles although urbanization processes have been reported in some South American Countries such as Colombia. Currently, few studies show the relative distribution of Leishmania species related to cutaneous Leishmaniasis (CL) in South America due to the lack of accurate surveillance and public health systems. Herein, we conducted a systematic estimation of the Leishmania species causing CL in Colombia from 1980 to 2001 via molecular typing and isoenzymes.

2018-02-01

Fluxes of continental runoff and sediments as well as downstream deposition of eroded soils have severely altered the structure and function of fluvial and deltaic-estuarine ecosystems. The Magdalena River, the main contributor of continental fluxes into the Caribbean Sea, delivers important amounts of water and sediments into Cartagena Bay, a major estuarine system in northern Colombia. Until now, trends in fluvial fluxes into the bay, as well as the relationship between these tendencies in fluvial inputs and associated upstream changes in the Magdalena catchment, have not been studied. Here we explore the interannual trends of water discharge and sediment load flowing from the Magdalena River-Canal del Dique system into Cartagena Bay during the last three decades, forecast future scenarios of fluxes into the bay, and discuss possible connections between observed trends in fluvial inputs and trends in human intervention in the Magdalena River basin. Significant upward trends in annual runoff and sediment load during the mid-1980s, 1990s, and post-2000 are observed in the Magdalena and in the Canal del Dique flowing into Cartagena Bay. During the last decade, Magdalena streamflow and sediment load experienced increases of 24% and 33%, respectively, compared to the pre-2000 year period. Meanwhile, the Canal del Dique witnessed increases in water discharge and sediment load of 28% and 48%, respectively. During 26 y of monitoring, the Canal del Dique has discharged 177 Mt of sediment to the coastal zone, of which 52 Mt was discharged into Cartagena Bay. Currently, the Canal drains 6.5% and transports 5.1% of the Magdalena water discharge and sediment load. By 2020, water discharge and sediment flux from the Canal del Dique flowing to the coastal zone will witness increments of 164% and 260%, respectively. Consequently, sediment fluxes into Cartagena Bay will witness increments as high as 8.2 Mt y- 1 or 317%. Further analyses of upstream sediment load series for 21

Typhoid Fever in nineteenth-century Colombia: between medical geography and bacteriology.

PubMed

García, Mónica

2014-01-01

This paper analyses how the Colombian medical elites made sense of typhoid fever before and during the inception of bacteriological ideas and practices in the second half of the nineteenth century. Assuming that the identity of typhoid fever has to be understood within the broader concerns of the medical community in question, I show how doctors first identified Bogotá's epidemics as typhoid fever during the 1850s, and how they also attached specificity to the fever amongst other continuous fevers, such as its European and North American counterparts. I also found that, in contrast with the discussions amongst their colleagues from other countries, debates about typhoid fever in 1860-70 among doctors in Colombia were framed within the medico-geographical scheme and strongly shaped by the fear of typhoid fever appearing alongside 'paludic' fevers in the highlands. By arguing in medico-geographical and clinical terms that typhoid fever had specificity in Colombia, and by denying the medico-geographical law of antagonism between typhoid and paludic fevers proposed by the Frenchman Charles Boudin, Colombian doctors managed to question European knowledge and claimed that typhoid fever had distinct features in Colombia. The focus on paludic and typhoid fevers in the highlands might explain why the bacteriological aetiology of typhoid fever was ignored and even contested during the 1880s. Anti-Pasteurian arguments were raised against its germ identity and some physicians even supported the idea of spontaneous origin of the disease. By the 1890s, Pasteurian knowledge had come to shape clinical and hygienic practices.

Background Malaria remains a serious problem in Colombia. The number of malaria cases is governed by multiple climatic and non-climatic factors. Malaria control policies, and climate controls such as rainfall and temperature variations associated with the El Niño/Southern Oscillation (ENSO), have been associated with malaria case numbers. Using historical climate data and annual malaria case number data from 1960 to 2006, statistical models are developed to isolate the effects of climate in each of Colombia's five contrasting geographical regions. Methods Because year to year climate variability associated with ENSO causes interannual variability in malaria case numbers, while changes in population and institutional control policy result in more gradual trends, the chosen predictors in the models are annual indices of the ENSO state (sea surface temperature [SST] in the tropical Pacific Ocean) and time reference indices keyed to two major malaria trends during the study period. Two models were used: a Poisson and a Negative Binomial regression model. Two ENSO indices, two time reference indices, and one dummy variable are chosen as candidate predictors. The analysis was conducted using the five geographical regions to match the similar aggregation used by the National Institute of Health for its official reports. Results The Negative Binomial regression model is found better suited to the malaria cases in Colombia. Both the trend variables and the ENSO measures are significant predictors of malaria case numbers in Colombia as a whole, and in two of the five regions. A one degree Celsius change in SST (indicating a weak to moderate ENSO event) is seen to translate to an approximate 20% increase in malaria cases, holding other variables constant. Conclusion Regional differentiation in the role of ENSO in understanding changes in Colombia's annual malaria burden during 1960–2006 was found, constituting a new approach to use ENSO as a significant predictor of the

The banana moko disease, caused by the bacterium Ralstonia solanacearum, is one of the most important phytopathological problems of the banana agribusiness in tropical countries. In Uraba and Magdalena (Colombia), the main exporting regions of banana in Colombia, this disease causes a destruction estimated in 16.5 ha/year. The bacterium presents an extremely high level of genetic variation that affects control measures. This is the first study of its variation in Colombia and was done with AFLP molecular markers on a population of 100 isolates from banana plants, soils and "weeds". The high level of genetic diversity, with Nei and Shannon indexes of h=0.32 and I=0.48, respectively, and the AMOVA, showed that this population is subestructured (Fst=0.66): the host is the main factor of differentiation. Even so, previous tests show that all varieties have pathogenicity on Musa.

Objective In the 1970s, OCPs and IUDs were the most popular contraceptive methods in Colombia. According to data from the most recent Demographic and Health Survey (DHS), sterilization has become the most common form of birth control in Colombia. This study aims to examine the characteristics of Colombian women desiring long-acting contraception. Methods This study uses the 2005 and 2010 Colombian DHS dataset. Women who choose long-acting contraception were divided into those using female sterilization and those using long-acting reversible contraception (LARC). A multivariate logistic regression model was used to compare demographic and social determinants of contraceptive choice among reproductive age women seeking long-acting contraception between the years 2005 and 2010. Results Among women using a long-acting contraceptive method in 2010, compared to 2005, women were significantly more likely to be sterilized (1.14 OR, 95% CI 1.09-1.18) and less likely to use LARC (0.88 OR, 95% CI 0.85-0.92). Of women seeking long-acting contraception, those exposed to a family planning provider were less likely to undergo sterilization (0.54 OR, 95% CI 0.51-0.58) and more likely to use LARC (1.84 OR, 95% CI 1.73-1.96). When compared to all contraceptive users, younger women and women with less than two children were more likely to use LARC than sterilization. Conclusion Between 2005 and 2010, an increase in the proportion of contracepting women being sterilized in Colombia occurred. Our findings suggest that exposure to a family planning provider and appropriate contraceptive counseling appears to be key determinants of long-acting contraceptive choice. To improve use of long-acting, effective contraception, efforts should be made to increase access to family planning providers.

Case-control studies of cervical intra-epithelial neoplasia grade III (CIN III) and of invasive cervical cancer were carried out in Spain and Colombia to assess the relationship between cervical cancer and 6 common sexually transmitted agents (STAs). The CIN-III studies included 525 cases and 512 controls matched for age and for the place of recruitment; the invasive-cancer studies included 373 histologically confirmed cases of squamous-cell carcinoma and 387 age-stratified controls selected randomly from the populations that generated the cases. Antibodies to Chlamydia trachomatis, Neisseria gonorrhoeae, Treponema pallidum, herpes simplex virus type II (HSV-2) and cytomegalovirus (CMV) were tested in 88% of the women. Cervical scrapes were examined for HPV DNA in 63% of the women using a polymerase-chain-reaction assay (PCR). Among controls, the highest antibody prevalence was to CMV (96.5%), followed by HSV-2 (31.4%) and C. trachomatis (23.3%). For all STAs, the sero-prevalence was markedly higher in Colombia than in Spain both for cases and for controls. After adjustment for the presence of HPV DNA, C. trachomatis was the only STA associated with CIN III in both countries; Spain and Colombia. In both countries, the risk of CIN III increased with increasing of C. trachomatis antibody titers. Among Spanish women, an increase in risk of invasive carcinoma was found for those with antibodies to N. gonorrhoeae; those with antibodies to HSV-2 and those with antibodies to C. trachomatis. These associations were present only in HPV-DNA-negative women. Among HPV-DNA-positive women, none of the STAs considered were associated with cervical neoplasia. Our findings could be interpreted as indicating that past infections with HSV-2, N. gonorrhoeae and C. trachomatis are surrogate markers of HPV, but because HPV DNA may have escaped detection, we cannot exclude that these STAs are also of separate etiological significance.

2014-01-01

The in vitro susceptibilities of 30 isolates of Plasmodium vivax to a number of antimalarials (chloroquine [CQ], mefloquine, amodiaquine, quinine, and artesunate [AS]) were evaluated. The isolates came from the region of Urabá in Colombia, in which malaria is endemic, and were evaluated by the schizont maturation test. The 50% inhibitory concentration (IC50) was 0.6 nM (95% confidence interval [CI], 0.3 to 1.0 nM) for artesunate, 8.5 nM (95% CI, 5.6 to 13.0 nM) for amodiaquine, 23.3 nM (95% CI, 12.4 to 44.1 nM) for chloroquine, 55.6 nM (95% CI, 36.8 to 84.1 nM) for mefloquine, and 115.3 nM (95% CI, 57.7 to 230.5 nM) for quinine. The isolates were classified according to whether the initial parasites were mature or immature trophozoites (Tfz). It was found that the IC50s for chloroquine and artesunate were significantly different in the two aforementioned groups (P < 0.001). The IC50s of CQ and AS were higher in the isolates from mature Tfz (CQ, 39.3 nM versus 17 nM; AS, 1.4 nM versus 0.3 nM), and 10% of the isolates showed lower susceptibilities to one of the antimalarial drugs, 13.3% to two antimalarial drugs, and 3.3% to more than three antimalarial drugs. It should be highlighted that despite the extensive use of chloroquine in Colombia, P. vivax continues to be susceptible to antimalarials. This is the first report, to our knowledge, showing in vitro susceptibilities of P. vivax isolates to antimalarials in Colombia. PMID:25114141

2010-05-01

Significant coral reef decline has been observed in Colombia during the last three decades. However, due to the lack of monitoring activities, most of the information about health and changes was fragmentary or inadequate. To develop an expanded nation-wide reef-monitoring program, in 1998 INVEMAR (Instituto de Investigaciones Marinas y Costeras: "Colombian Institute of Marine and Coastal Research") designed and implemented SIMAC (Sistema Nacional de Monitorco de Arrecifes Coralinos en Colombia: "National Monitoring System of Coral Reefs in Colombia") with the participation of other institutions. By the end of 2003 the SIMAC network reached more than twice its initial size, covering ten reef areas (seven in the Caribbean and three in the Pacific), 63 reef sites and 263 permanent transects. SIMAC monitoring continued without interruption until 2008 and should persist in the long-term. The SIMAC has a large database and consists basically of water quality measurements (temperature, salinity, turbidity) and a yearly estimation of benthic reef cover, coral disease prevalence, gorgonian density, abundance of important mobile invertebrates, fish diversity and abundance of important fish species. A methods manual is available in the Internet. Data and results of SIMAC have been widely circulated through a summary report published annually since 2000 for the Colombian environmental agencies and the general public, as well as numerous national and international scientific papers and presentations at meetings. SIMAC information has contributed to support regional and global reef monitoring networks and databases (i.e. CARICOMP, GCRMN, ReefBase).

In Colombia, the main vectors of Trypanosoma cruzi, the causative agent of Chagas disease, are Rhodnius prolixus and Triatoma dimidiata. T. dimidiata is present in the east region of Colombia as domestic, peridomestic, and sylvatic populations, resulting in difficulties for its control. A cost-effective way to prioritize houses for treatment is to stratify houses based on risk factors. In this study, risk factors were evaluated for potential associations with domicile infestation of T. dimidiata. There was an increased likelihood of domestic infestation associated with the presence of mixed roofs (odds ratio [OR] = 36.14, 95% confidence interval [95% CI] = 12.21-106.97), cats (OR = 3.94, 95% CI = 1.36-11.38), rock piles (OR = 5.28, 95% CI = 1.64-16.98), and bushes with height above 10 m (OR = 11.21, 95% CI = 2.08-60.45). These factors could be used to target surveillance and control of T. dimidiata to houses with an increased risk of being infested. © The American Society of Tropical Medicine and Hygiene.

2013-09-01

Recognition of seismogenic zones in geographical regions supports seismic hazard studies. This recognition is usually based on visual, qualitative and subjective analysis of data. Spatial pattern recognition provides a well founded means to obtain relevant information from large amounts of data. The purpose of this work is to identify and classify spatial patterns in instrumental data of the South West Colombian seismic database. In this research, clustering tendency analysis validates whether seismic database possesses a clustering structure. A non-supervised fuzzy clustering algorithm creates groups of seismic events. Given the sensitivity of fuzzy clustering algorithms to centroid initial positions, we proposed a methodology to initialize centroids that generates stable partitions with respect to centroid initialization. As a result of this work, a public software tool provides the user with the routines developed for clustering methodology. The analysis of the seismogenic zones obtained reveals meaningful spatial patterns in South-West Colombia. The clustering analysis provides a quantitative location and dispersion of seismogenic zones that facilitates seismological interpretations of seismic activities in South West Colombia.

The latest seismological equipment and data processing instrumentation installed at the Colombia Seismological Network (RSNC) are described. System configuration, network operation, and data management are discussed. The data quality and the new seismological products are analyzed. The main purpose of the network is to monitor local seismicity with a special emphasis on seismic activity surrounding the Colombian Pacific and Caribbean oceans, for early warning in case a Tsunami is produced by an earthquake. The Colombian territory is located at the South America northwestern corner, here three tectonic plates converge: Nazca, Caribbean and the South American. The dynamics of these plates, when resulting in earthquakes, is continuously monitored by the network. In 2012, the RSNC registered in 2012 an average of 67 events per day; from this number, a mean of 36 earthquakes were possible to be located well. In 2010 the network was also able to register an average of 67 events, but it was only possible to locate a mean of 28 earthquakes daily. This difference is due to the expansion of the network. The network is made up of 84 stations equipped with different kind of broadband 40s, 120s seismometers, accelerometers and short period 1s sensors. The signal is transmitted continuously in real-time to the Central Recording Center located at Bogotá, using satellite, telemetry, and Internet. Moreover, there are some other stations which are required to collect the information in situ. Data is recorded and processed digitally using two different systems, EARTHWORM and SEISAN, which are able to process and share the information between them. The RSNC has designed and implemented a web system to share the seismological data. This innovative system uses tools like Java Script, Oracle and programming languages like PHP to allow the users to access the seismicity registered by the network almost in real time as well as to download the waveform and technical details.

2014-03-01

Malpelo Island is located 380km off the mainland continental coast of Colombia, in the Pacific Ocean. Several geological, ecological, and zoological studies, both marine and terrestrial, have been conducted in this island. Despite some marginal comments on some publications, no single specific survey has been devoted to botany so far. In order to make a floristic inventory of the terrestrial flora of this island, three field trips were made in 2010 to collect vascular plants, mosses, and lichens, as well as data on their distribution within the island. We collected and identified 25 species of lichens, two species of vascular plants and one moss. Lichens were the most diverse group found, including records of four new genera (Endocarpon, Fuscidea, Lecanographa and Verrucaria) and 13 new species for Colombia. The high lichen richness on Malpelo might be explained by their efficient form of asexual reproduction (soredia and isidia), that may have facilitated their transport to the island by migrating birds or wind. Once on the island, it is possible that lichens persist by being chemically protected against herbivores. The great number of new generic and species records for Colombia is explained by the low number of studies in saxicolous lichens conducted so far in the country, particularly on coastal areas and remote islands. Only two species of vascular plants were collected, a grass, Paspalum sp., and a fern, Pityrogramma calomelanos, and both of them correspond to new determinations for Malpelo. A moss species previously reported but with no positive identification was collected and identified as Octoblepharum albidum. Other species previously reported, for example, some species of shrubs, were not observed. The low number of vascular plants is probably due to a combination of soil conditions and herbivory by land crabs. This study is the first complete inventory of the flora of Malpelo and is a starting and reference point for future comparisons among islands in

Characteristics of Trypanosoma cruzi infection were studied in a rural area of the eastern plains of Colombia. Using enzyme-linked immunosorbent assay and indirect fluorescent-antibody tests, the infection was determined in 11.6% of the inhabitants of 142 dwellings. During 6 months of community surveillance, in 42.3% dwellings, 609 triatomines were collected (597 Rhodnius prolixus and seven, three, one, and one of Panstrongylus geniculatus, Psammolestes arturi, Eratyrus mucronatus, and Triatoma maculata, respectively). Rhodnius prolixus was found in 80% peridomiciliary Attalea butyracea palms examined with baited traps, and its infection with T. cruzi was 30% and 38.5% in dwellings and palms, respectively. Trypanosoma cruzi was isolated in five of 35 triatomines and in one of 24 dogs. The blood of domestic and wild animals was identified in triatomines collected in the intradomicile and in palms. These results support the extension of the wild cycle of T. cruzi to human dwellings and the characterization of a new scenario for transmission in Colombia. PMID:26728765

PubMed

Echeverri, Oscar

2008-09-01

This is a succinct analysis of the circular relationship between health and development and the changes occurring over recent decades regarding health care services production and delivery that have resulted in a new paradigm. From the late 1970s through the 1980s, three major, worldwide shifts occurred that changed health care services in Colombia and in other Latin American countries: the privatization of government entities, the commodification of health care services, and the failure of the Soviet model. Health care system reform in Colombia, considered by some experts to be a model, is an example of health care commodification that, 15 years later, has not achieved the coverage, nor the equity, nor the efficiency, nor the quality, that it should have. More so than the market, the problem has been with the market entities that seek disproportionate profits. A solution for this situation is to appeal to nonprofit organizations for the purchase and sale of health care services.

Seismic anisotropy and slab dynamics from SKS splitting recorded in Colombia

NASA Astrophysics Data System (ADS)

Porritt, Robert W.; Becker, Thorsten W.; Monsalve, Gaspar

2014-12-01

The Nazca, Caribbean, and South America plates meet in northwestern South America where the northern end of the Andean volcanic arc and Wadati-Benioff zone seismicity indicate ongoing subduction. However, the termination of Quaternary volcanism at ~5.5°N and eastward offset in seismicity underneath Colombia suggest the presence of complex slab geometry. To help link geometry to dynamics, we analyze SKS splitting for 38 broadband stations of the Colombian national network. Measurements of fast polarization axes in western Colombia close to the trench show dominantly trench-perpendicular orientations. Orientations measured at stations in the back arc, farther to the east, however, abruptly change to roughly trench parallel anisotropy. This may indicate along-arc mantle flow, possibly related to the suggested "Caldas" slab tear, or a lithospheric signature, but smaller-scale variations in anisotropy remain to be explained. Our observations are atypical globally and challenge our understanding of the complexities of subduction zone seismic anisotropy.

Anemia affects approximately 25% of school-aged children (SAC—aged 5.00–14.99 years) globally. We determined in three countries the prevalence and determinants of anemia in SAC. Data on sociodemographics, inflammation and nutrition status were obtained from the 2006 Mexican National Nutrition Survey, the 2003-6 US National Health and Nutrition Examination Surveys, and the 2010 Encuesta Nacional de Nutrición Situación Colombia. In the US, vitamin A and iron deficiency (ID) were available only for girls aged 12.00–14.99 years to which our analysis was limited. Associations were evaluated by country using multivariable logistic regression adjusting for confounders and complex survey design. The prevalence of anemia and ID were: Mexico 12% (ID 18%), n = 3660; US 4% (ID 10%), n = 733; and Colombia 4% (ID 9%), n = 8573. The percentage of anemia associated with ID was 22.4% in Mexico, 38.9% in the US and 16.7% in Colombia. In Mexico, anemia was associated with ID (adjusted OR: 1.5, p = 0.02) and overweight (aOR 0.4, p = 0.007). In the US, anemia was associated with black race/ethnicity (aOR: 14.1, p < 0.0001) and ID (aOR: 8.0, p < 0.0001). In Colombia, anemia was associated with black race/ethnicity (aOR: 1.6, p = 0.005), lowest socio-economic status quintile (aOR: 1.8, p = 0.0005), ID (aOR: 2.7, p < 0.0001), and being stunted (aOR: 1.6, p = 0.02). While anemia was uniformly associated with iron deficiency in Mexico, Columbia, and the United States, other measured factors showed inconsistent associations with anemia. Additional data on anemia determinants in SAC are needed to guide interventions. PMID:27347992

An analysis of hydrologic variability in Colombia shows different seasonal effects associated with El Niño/Southern Oscillation (ENSO) phenomenon. Spectral and cross-correlation analyses are developed between climatic indices of the tropical Pacific Ocean and the annual cycle of Colombia's hydrology: precipitation, river flows, soil moisture, and the Normalized Difference Vegetation Index (NDVI). Our findings indicate stronger anomalies during December-February and weaker during March-May. The effects of ENSO are stronger for streamflow than for precipitation, owing to concomitant effects on soil moisture and evapotranspiration. We studied time variability of 10-day average volumetric soil moisture, collected at the tropical Andes of central Colombia at depths of 20 and 40 cm, in coffee growing areas characterized by shading vegetation ("shaded coffee"), forest, and sunlit coffee. The annual and interannual variability of soil moisture are highly intertwined for the period 1997-1999, during strong El Niño and La Niña events. Soil moisture exhibited greater negative anomalies during 1997-1998 El Niño, being strongest during the two dry seasons that normally occur in central Colombia. Soil moisture deficits were more drastic at zones covered by sunlit coffee than at those covered by forest and shaded coffee. Soil moisture responds to wetter than normal precipitation conditions during La Niña 1998-1999, reaching maximum levels throughout that period. The probability density function of soil moisture records is highly skewed and exhibits different kinds of multimodality depending upon land cover type. NDVI exhibits strong negative anomalies throughout the year during El Niños, in particular during September-November (year 0) and June-August (year 0). The strong negative relation between NDVI and El Niño has enormous implications for carbon, water, and energy budgets over the region, including the tropical Andes and Amazon River basin.

The prevalence of Toxoplasma gondii in free-ranging chickens is a good indicator of the prevalence of T. gondii oocysts in the soil because chickens feed from the ground. The prevalence of T. gondii in 77 free-range chickens (Gallus domesticus) from Colombia, South America was determined. Antibodies to T. gondii were assayed by the modified agglutination test (MAT), and found in 32 (44.4%) of 72 chickens with titers of 1:5 in 4, 1:10 in 3, 1:20 in 1, 1:40 in 1, 1:80 in 8, 1:160 in 8, 1:320 in 3, and 1:640 or higher in 4. Hearts and brains of 31 seropositive chickens were pooled and bioassayed in mice. Tissues from 32 (16+16) seronegative chickens were pooled and fed to two, T. gondii-free cats, and tissues from nine chickens without matching sera were fed to one T. gondii-free cat. Feces of cats were examined for oocysts. T. gondii oocysts were excreted by a cat that was fed tissues of 16 seronegative chickens. T. gondii was isolated by bioassay in mice from 23 chickens with MAT titers of 1:20 or higher. All infected mice from 16 of the 23 isolates died of toxoplasmosis. Overall, 82 (81.1%) of 101 mice that became infected after inoculation with chicken tissues died of toxoplasmosis. Genotyping of these 24 isolates using polymorphisms at the SAG2 locus indicated that seven T. gondii isolates were Type I, 17 were Type III, and none was Type II. Phenotypically, T. gondii isolates from chickens from Colombia were similar to isolates from Brazil but different from the isolates from North America; most isolates from chickens from Brazil and Colombia were lethal for mice whereas isolates from North America did not kill inoculated mice. Genetically, none of the T. gondii isolates from Colombia and Brazil was SAG2 Type II, whereas most isolates from chickens from North America were Type II. This is the first report of genetic characterization of T. gondii isolates from Colombia, South America.

Abstract Background Trends in distribution of S. pneumoniae capsular serotypes are associated with the introduction of pneumococcal conjugate vaccines (PCV) among population. In Colombia, 10-valent PCV (PCV10) has been included in the national vaccination program since 2011. As a part of the pneumococcal surveillance network (SIREVA), Colombia has gathered data of serotype distribution since 1993. The aim of this work is to determine the effect of PCV10 introduction on non-coverage serotypes by PCV10 in Colombia, specifically, the effect on 6A, 19A and 3 serotypes. Methods Information was obtained from the national surveillance program since 1993 to 2016 in children under 5 years. The isolates came from sterile sites (blood, cerebrospinal fluid, pleural fluid, articular and peritoneal fluids). All the isolates were serotyping by National Institute of Health. An interrupted time series analysis was performed to determine the effect of the PCV10 introduction on the 6A, 19A and 3 serotypes (ARIMA model). Results Serotyping was performed in 4683 isolates. The annual proportion trend of the 6A, 19A and 3 serotypes remained constant until 2012. An increase of double in the serotype proportion trends was observed after 2012 (Figure). The interrupted time-series analysis showed a positive effect of the PCV10 introduction on trends of 19A and 3 serotypes, with coefficients 20.92 (P = 0.00, ARIMA(2,0,1)) and 6.32 (P = 0.00, ARIMA(2,1,1), respectively. There was no significant effect on 6A serotype trend. Conclusion The introduction of PCV10 in the national vaccination program in Colombia, affected the distribution of PVC 13 capsular types non included in the PCV 7 and PCV 10 in children under 5 years. This information emphasizes the importance to surveillance the changes in serotype distributions to guide prevention strategies in children under 5 years in Colombia.

The Arribalzagia Series of the Anopheles Subgenus comprises morphologically similar species or members of species complexes which makes correct species identification difficult. Therefore, the aim of this work was to discriminate the morphospecies of the Arribalzagia Series present in Colombia using a multilocus approach based on ITS2, COI and CAD sequences. Specimens of the Arribalzagia Series collected at 32 localities in nine departments were allocated to seven species. Individual and concatenated Bayesian analyses showed high support for each of the species and reinforced the previous report of the Apicimacula species Complex with distribution in the Pacific Coast and northwestern Colombia. In addition, a new molecular operational taxonomic unit-MOTU was identified, herein denominated near Anopheles peryassui, providing support for the existence of a Peryassui species Complex. Further, the CAD gene, just recently used for Anopheles taxonomy and phylogeny, demonstrated its power in resolving phylogenetic relationships among species of the Arribalzagia Series. The divergence times for these species correspond to the early Pliocene and the Miocene. Considering the epidemiological importance of some species of the Series and their co-occurrence in malaria endemic regions of Colombia, their discrimination constitutes an important step for vector incrimination and control in the country.

Designing and validating instruments for identifying public health problems in some zoological parks in Colombia, thereby allowing them to be evaluated. Four instruments were designed and validated along with the participation of five zoos. The instruments were validated regarding appearance, content, sensitivity to change, reliability tests and determining the tools' usefulness. An evaluation scale was created which assigned a maximum of 400 points, having the following evaluation intervals: 350-400 points meant good public health management, 100-349 points for regular management and 0-99 points for deficient management. The instruments were applied to the five zoos as part of the validation, forming a base-line for future evaluation of public health in them. Four valid and useful instruments were obtained for evaluating public health in zoos in Colombia. The five zoos presented regular public health management. The base-line obtained when validating the instruments led to identifying strengths and weaknesses regarding public health management in the zoos. The instruments obtained generally and specifically evaluated public health management; they led to diagnosing, identifying, quantifying and scoring zoos in Colombia in terms of public health. The base-line provided a starting point for making comparisons and enabling future follow-up of public health in Colombian zoos.

This study examined the connections between family dynamics and the mental health of caregivers of youth with spinal cord injuries/disorders (SCI/D) caregivers from Colombia, South America. It was hypothesized that lower family functioning would be associated with poorer caregiver mental health. A cross-sectional study of self-report data collected from caregivers through the Hospital Universatario Hernando Moncaleano Perdomo in Neiva, Colombia. Thirty caregivers of children with SCI/D from Nevia, Colombia who were a primary caregiver for ≥3 months, providing care for an individual who was ≥6 months post-injury/diagnosis, familiar with the patient's history, and without neurological or psychiatric conditions. Caregivers' average age was 41.30 years (SD = 10.98), and 90% were female. Caregivers completed Spanish versions of instruments assessing their own mental health and family dynamics. Family dynamics explained 43.2% of the variance in caregiver burden and 50.1% of the variance in satisfaction with life, although family dynamics were not significantly associated with caregiver depression in the overall analysis. Family satisfaction was the only family dynamics variable to yield a significant unique association with any index of caregiver mental health (satisfaction with life). If similar findings emerge in future intervention research, interventions for pediatric SCI/D caregivers in Colombia and other similar global regions could benefit from including techniques to improve family dynamics, especially family satisfaction, given the strong potentially reciprocal connection between these dynamics and caregiver mental health. The degree of disability resulting from SCI/D can vary greatly depending on the severity and level of the lesion, though permanent impairment is often present that profoundly impacts both physical and psychological functioning. Very little is known about the impact of pediatric SCI/D in developing countries, despite the high rates of

Association between economic growth and injury mortality among seniors in Colombia.

Injuries among seniors are recognised as an important public health problem not only in developed countries but also in middle-income countries. There is ample epidemiological literature that relates economic growth to the reduction of infectious and childhood diseases. Less evidence exists to document if economic growth alone is enough to reverse the increasing trends of injury mortality and morbidity among seniors in a middle-income country. To investigate the association between economic growth and injury deaths among older people in Colombia. Using data from Colombia, 1979-2006 (n=28), time-series models were used to ascertain if the variation over time in injury mortality among seniors is related to short-term oscillations in economic performance. Four empirical specifications usually used in the analysis of such data were implemented. Models were run by type of injury and gender. A negative but moderate effect of economic growth was found on injury deaths among older people. The reported elasticity was between -0.98 and -1.26. Men benefit from economic growth more than women. Economic growth seems to reduce traffic injuries, suicides and homicides. A positive association was also found between falls and growth in gross domestic product. The results indicate a non-homogeneous association between economic growth and injury deaths among seniors in Colombia. This association is usually stronger in a negative direction among children and younger adults. Although more research is needed to understand the causal relationship between economic growth and injury, the association found may suggest that economic growth may not be sufficient to reverse injury deaths among older people; therefore, additional health policies need to be in place to reduce mortality due to preventable injuries in seniors.

The 1906 Colombia-Ecuador earthquake induced both strong seismic motions and a tsunami, the most destructive earthquake in the history of the Colombia-Ecuador subduction zone. The tsunami propagated across the Pacific Ocean, and its waveforms were observed at tide gauge stations in countries including Panama, Japan, and the USA. This study conducted slip inverse analysis for the 1906 earthquake using these waveforms. A digital dataset of observed tsunami waveforms at the Naos Island (Panama) and Honolulu (USA) tide gauge stations, where the tsunami was clearly observed, was first produced by consulting documents. Next, the two waveforms were applied in an inverse analysis as the target waveform. The results of this analysis indicated that the moment magnitude of the 1906 earthquake ranged from 8.3 to 8.6. Moreover, the dominant slip occurred in the northern part of the assumed source region near the coast of Colombia, where little significant seismicity has occurred, rather than in the southern part. The results also indicated that the source area, with significant slip, covered a long distance, including the southern, central, and northern parts of the region.[Figure not available: see fulltext.

Eulerian 3-D chemistry transport models (CTM) have been widely used for the study of air quality in urban environments, becoming an essential tool for studying the impacts and dynamics of gases and aerosols on air quality. However, their use in Colombia is scarce, especially in medium-sized cities, which are experimenting a fast urban growth, increasing the risk associated with possible air pollution episodes. In the densely populated medium-sized Andean city of Manizales, Colombia - a city located on the western slopes of the central range of the Andes (urban population 368000; 2150 m.a.s.l), there is an influence of the active Nevado del Ruiz volcano, located 28 km to the southwest. This natural source emits daily gas and particle fluxes, which could influence the atmospheric chemistry of the city and neighboring towns. Hence, the zone presents a unique combination of anthropogenic and volcanic sulfur gas emissions, which affects SO2 dynamics in the urban area, influencing also in the formation of acid rain phenomenon in the city. Therefore, studies analyzing the relative contribution of anthropogenic and volcanic emission could contribute with a deep understanding about causes and dynamics of both acid rain phenomenon and ambient SO2 levels in Manizales. This work aimed to analyze the influence of anthropogenic (on-road vehicular and industrial point-sources) and volcanic sulfur emissions in SO2 atmospheric chemistry dynamics, evaluating its possible effects on acid rain profiles. Ambient SO2 levels and day-night rain samples were measured and used to analyze results obtained from the application of the fully-coupled on-line WRF-Chem model. Two high-resolution simulations were performed during two dry and wet one-week periods in 2015. Analysis of SO2 dispersion patterns and comparison with SO2 observations in the urban area were performed for three different scenarios in which natural and anthropogenic emissions were simulated separately. Results suggest that

Predicted altitudinal shifts and reduced spatial distribution of Leishmania infantum vector species under climate change scenarios in Colombia.

Visceral leishmaniasis (VL) is caused by the trypanosomatid parasite Leishmania infantum (=Leishmania chagasi), and is epidemiologically relevant due to its wide geographic distribution, the number of annual cases reported and the increase in its co-infection with HIV. Two vector species have been incriminated in the Americas: Lutzomyia longipalpis and Lutzomyia evansi. In Colombia, L. longipalpis is distributed along the Magdalena River Valley while L. evansi is only found in the northern part of the Country. Regarding the epidemiology of the disease, in Colombia the incidence of VL has decreased over the last few years without any intervention being implemented. Additionally, changes in transmission cycles have been reported with urban transmission occurring in the Caribbean Coast. In Europe and North America climate change seems to be driving a latitudinal shift of leishmaniasis transmission. Here, we explored the spatial distribution of the two known vector species of L. infantum in Colombia and projected its future distribution into climate change scenarios to establish the expansion potential of the disease. An updated database including L. longipalpis and L. evansi collection records from Colombia was compiled. Ecological niche models were performed for each species using the Maxent software and 13 Worldclim bioclimatic coverages. Projections were made for the pessimistic CSIRO A2 scenario, which predicts the higher increase in temperature due to non-emission reduction, and the optimistic Hadley B2 Scenario predicting the minimum increase in temperature. The database contained 23 records for L. evansi and 39 records for L. longipalpis, distributed along the Magdalena River Valley and the Caribbean Coast, where the potential distribution areas of both species were also predicted by Maxent. Climate change projections showed a general overall reduction in the spatial distribution of the two vector species, promoting a shift in altitudinal distribution for L

Essential oils (EOs) are widely used as biopesticides and to control bacterial infections. This study describes the ability of six EOs isolated from plants cultivated in Colombia to perform as repellents against Ulomoides dermestoides and as quorum sensing (QS) inhibitors. EOs from Aloysia triphylla, Cymbopogon nardus, Lippia origanoides, Hyptis suaveolens, Swinglea glutinosa and Eucalyptus globulus were repellents classified as Class IV, IV, IV, III, II, and II, respectively, whereas the commercial repellent IR3535 only reached Class II after 2 h exposure. All EOs presented small, but significant inhibitory properties against the QS system in Escherichia coli (pJBA132) at 25 μg/mL after 4 h exposure. These data suggest evaluated EOs from Colombia are sustainable, promising new sources of natural repellents and could be important as anti-quorum sensing molecules.

The people of Tumaco-La Tolita culture inhabited the borders of present-day Colombia and Ecuador. Already extinct by the time of the Spaniards arrival, they left a huge collection of pottery artifacts depicting everyday life; among these, disease representations were frequently crafted. In this article, we present the results of the personal examination of the largest collections of Tumaco-La Tolita pottery in Colombia and Ecuador; cases of Down syndrome, achondroplasia, mucopolysaccharidosis I H, mucopolysaccharidosis IV, a tumor of the face and a benign tumor in an old woman were found. We believe these to be among the earliest artistic representations of disease.

In some countries the misuse and diversion of prescribed opioid analgesic is increasing considerably, but there is no official data regarding the situation in Colombia. The aim of this study was to identify all dependent to opioid analgesics legally prescribed patients that were treated in a University Hospital in Medellin, Colombia during 4 years and to characterize this population. Observational study in a University Hospital in Medellin, Colombia, searching for patients with ICD-10 codes related with opioid related disorders, adverse events or pain and treated between January 2011 and December 2014. Sixty patients with opioid dependence according to DSM-IV criteria were found from 3332 clinical charts reviewed. The median age was 43 years. Although all patients met the DSM-IV criteria, 33 % of patients were wrongly diagnosed by other ICD-10 codes. Almost all patient (88 %) initiated opioids after medical prescription although the adherence to pain scale was low (25 %). The median time of consumption was 48 months. Tramadol was the opioid more frequently used by patients, followed by morphine and oxycodone. A statistically significant higher consumption of other psychotropic substances was observed in male than female (P = 0.005 by Fisher's test). After be diagnosed, 55 % of patients gone a methadone-based replacement therapy. Legally prescribed opioid dependence was belatedly diagnosed in 60 patients in a University hospital, after prolonged use of drugs to treat chronic pain and with low adherence to pain scale or guidelines. This is the first report in Colombia.

By 2016, tobacco industry provided the only illicit trade estimates in Colombia and used these to discourage tax increases since the 1990s. To establish the viability of a threefold hike in the excise tax, policy makers needed unbiased estimates of the illicit cigarette. To estimate the size of illicit cigarette trade in five Colombian cities (63% of the market), analyse characteristics of smokers of illicit cigarettes and compare market share results with one industry-funded survey. Street cross-sectional survey with smokers' self-report on consumption pattern, last purchase information and direct observation of smoker's packs. Sampling frame: smokers, men and women, 12 years old or older, all income levels, resident in five Colombian cities (Bogotá, Medellín, Cali, Cartagena and Cúcuta) with 1 733 316 smokers in 2013. Sample size 1697, simple random sample by city, sampling weights based on age groups and cities. Confidence level 95%, margin of error 3.5% for Bogotá and Medellín and 5% for the other three cities. Data collection period: 24 August-14 September 2016. Illicit cigarettes represent 3.5% of consumption in the five cities, a much lower estimate than the industry data. There are significant differences across cities, with Bogotá at the bottom (1.5%) and Cúcuta at the top (22.8%). The low overall penetration of illicit cigarettes in Colombia indicates that the industry's warnings against tax increases are not justified. The limited importance of tax levels as determinant of consumption of illicit cigarettes is also suggested by the differences across cities, all of them with the same tax regime. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Congenital malaria in Urabá, Colombia

PubMed Central

2011-01-01

Background Congenital malaria has been considered a rare event; however, recent reports have shown frequencies ranging from 3% to 54.2% among newborns of mothers who had suffered malaria during pregnancy. There are only a few references concerning the epidemiological impact of this entity in Latin-America and Colombia. Objective The aim of the study was to measure the prevalence of congenital malaria in an endemic Colombian region and to determine some of its characteristics. Methods A prospective, descriptive study was carried out in the mothers who suffered malaria during pregnancy and their newborns. Neonates were clinically evaluated at birth and screened for Plasmodium spp. infection by thick smear from the umbilical cord and peripheral blood, and followed-up weekly during the first 21 days of postnatal life through clinical examinations and thick smears. Results 116 newborns were included in the study and 80 umbilical cord samples were obtained. Five cases of congenital infection were identified (four caused by P. vivax and one by P. falciparum), two in umbilical cord blood and three in newborn peripheral blood. One case was diagnosed at birth and the others during follow-up. Prevalence of congenital infection was 4.3%. One of the infected newborns was severely ill, while the others were asymptomatic and apparently healthy. The mothers of the newborns with congenital malaria had been diagnosed with malaria in the last trimester of pregnancy or during delivery, and also presented placental infection. Conclusions Congenital malaria may be a frequent event in newborns of mothers who have suffered malaria during pregnancy in Colombia. An association was found between congenital malaria and the diagnosis of malaria in the mother during the last trimester of pregnancy or during delivery, and the presence of placental infection.

2002-04-01

A lymphocystis-like condition produced hemorrhagic lesions over the bodies of pacora Plagioscion surinamensis (Bleeker) (Perciformes: Sciaenidae) held in freshwater aquaculture in northern Colombia and increased their sensitivity to handling stress. This disease eliminated this fish from a project evaluating its aquaculture potential. Lymphocystis disease is assumed to be less damaging to the host. This condition requires more study and histological evaluation.

Poisoning due to pesticides is an important public health problem worldwide due its morbidity and mortality. In Colombia, there are no exact data on mortality due to pesticide poisoning. To estimate the trend of mortality rate due to pesticide poisoning in Colombia between 1998 and 2011. We carried out a descriptive analysis with the database reports of death as unintentional poisoning, self-inflicted intentional poisoning, aggression with pesticides, and poisoning with non-identified intentionality, population projections between 1998 and 2011, and rurality indexes. Crude and age-adjusted mortality rates were estimated and trends and Spearman coefficients were evaluated. A total of 4,835 deaths were registered (age-adjusted mortality rate of 2.38 deaths per 100,000 people). Mortality rates were higher in rural areas, for self-inflicted intentional poisoning, in men and in age groups between 15 and 39 years old. The trend has been decreasing since 2002. Municipality mortality rates due to unintentional poisoning and aggression correlated significantly with the rurality index in less rural municipalities. Mortality rates due to pesticide poisoning presented a mild decrease between 1998 and 2011. It is necessary to adjust and reinforce the measures conducive to reducing pesticide exposure in order to avoid poisoning and reduce mortality.

Describe changes in the population structure of Colombia's municipalities in relation to internal displacement in response to armed violence. A descriptive ecological study was carried out. Secondary sources were consulted, taken from the Consolidated Registry of Displaced Population and from the National Administrative Department of Statistics, to calculate expulsion and reception rates for population displaced by violence from 2002 to 2010. Based on these rates, four groups were created of municipalities in the extreme quartile for each rate during the entire period, which were classified as high expulsion, low expulsion, high reception, and low reception. Subsequently, population pyramids and structure indicators were constructed for each group of municipalities for two comparative reference years (1985 and 2010). Municipalities with high expulsion or reception rates experienced a slower epidemiological transition, with lower mean ages and aging indices. The high expulsion group had the least regression, based on the Sundbärg index. In the high reception group, the masculinity ratio decreased the most, especially among the economically active population, and it had the highest population growth. Population dynamics in Colombia have been affected by armed violence and changes in these dynamics are not uniform across the country, leading to important social, economic, and cultural consequences. This study is useful for decision-making and public policy making.

Barriers to Diagnosis Access for Chagas Disease in Colombia

Chagas disease is the leading cause of nonischemic cardiomyopathy in Latin America. Timely access to diagnosis and trypanocidal treatment and preventive tools for millions of infected people continues to be a challenge. The purpose of this study was to identify potential barriers for the diagnosis of Chagas disease in Colombia from the perspective of healthcare providers. Using a simultaneous mixed-methods study design, we analyzed trends in access to screening and diagnosis for Chagas disease in Colombia and assessed the national barriers to access. The main barriers to access at the national level included a limited governmental public health infrastructure for the diagnosis of Chagas disease and limited physician awareness and knowledge of the disease. Data indicate that 1.5% of total expected cases based on national prevalence estimates were reported. Few public health laboratories have the capacity to perform complementary tests for the diagnosis of Chagas disease and almost 6 months elapse between the requests of the tests and the confirmation of the disease. This study shows that infected people must overcome a number of barriers to achieve diagnosis. Reducing barriers to early diagnosis of Chagas disease is an important goal in the fight against the disease. PMID:29568648

Assessing the impact of subsidized healthcare insurance on access to cervical cytology in Medellin, Colombia. Propensity score matching (PSM) was used with 2008 Life Quality Survey in Colombia figures to obtain a control group comparable to a treatment group. This involved using stratification estimates, the k-nearest-neighbor algorithm and kernel density for calculating impact size Access to cytology for 19 to 49 year-old women having subsidized healthcare insurance were 2.2 % to 2.9 % lower compared to women who did not have any healthcare insurance. Estimates were not statistically significant for women over 50 years-old. Women lacking healthcare insurance having increased access to cytology could be explained by charities or social programs aiding the population lacking healthcare insurance.

2012-01-01

Fishes at Isla del Coco National Park, Costa Rica, were surveyed as part of a larger scientific expedition to the area in September 2009. The average total biomass of nearshore fishes was 7.8 tonnes per ha, among the largest observed in the tropics, with apex predators such as sharks, jacks, and groupers accounting for nearly 40% of the total biomass. The abundance of reef and pelagic sharks, particularly large aggregations of threatened species such as the scalloped hammerhead shark (up to 42 hammerheads ha-1) and large schools of jacks and snappers show the capacity for high biomass in unfished ecosystems in the Eastern Tropical Pacific. However, the abundance of hammerhead and reef whitetip sharks appears to have been declining since the late 1990s, and likely causes may include increasing fishing pressure on sharks in the region and illegal fishing inside the Park. One Galapagos shark tagged on September 20, 2009 in the Isla del Coco National Park moved 255km southeast towards Malpelo Island in Colombia, when it stopped transmitting. These results contribute to the evidence that sharks conduct large-scale movements between marine protected areas (Isla del Coco, Malpelo, Galápagos) in the Eastern tropical Pacific and emphasize the need for regional-scale management. More than half of the species and 90% of the individuals observed were endemic to the tropical eastern Pacific. These high biomass and endemicity values highlight the uniqueness of the fish assemblage at Isla del Coco and its importance as a global biodiversity hotspot.

Lahars at Cotopaxi and Tungurahua Volcanoes, Ecuador: Highlights from stratigraphy and observational records and related downstream hazards: Chapter 6

USGS Publications Warehouse

Mothes, Patricia A; Vallance, James W.

2015-01-01

Lahars are volcanic debris flows that are dubbed primary when triggered by eruptive activity or secondary when triggered by other factors such as heavy rainfall after eruptive activity has waned. Variation in time and space of the proportion of sediment to water within a lahar dictates lahar flow phase and the resultant sedimentary character of deposits. Characteristics of source material and of debris eroded and incorporated during flow downstream may strongly affect the grain-size composition of flowing lahars and their deposits. Lahars borne on the flanks of two steep-sided stratocones in Ecuador exemplify two important lahar types. Glacier-clad Cotopaxi volcano has been a producer of primary lahars that flow great distances downstream. Such primary lahars include those of both clast-rich and matrix-rich composition—some of which have flowed as far as 325 km to the Pacific Ocean. Cotopaxi's last important eruption in 1877 generated formidable syneruptive lahars comparable in size to those that buried Armero, Colombia, following the 1985 eruption of Nevado del Ruiz volcano. In contrast, ash-producing eruptive activity during the past 15 years at Tungurahua volcano has generated a continual supply of fresh volcaniclastic debris that is regularly remobilized by precipitation. Between 2000 and 2011, 886 rain-generated lahars were registered at Tungurahua. These two volcanoes pose dramatically different hazards to nearby populations. At Tungurahua, the frequency and small sizes of lahars have resulted in effective mitigation measures. At Cotopaxi 137 years have passed since the last important lahar-producing eruption, and there is now a high-risk situation for more than 100,000 people living in downstream valleys.

A mediated modelling approach to promote collaborative learning in Andean rural micro-catchments in Colombia

2013-04-01

In rural catchments of developing countries water-related diseases, due to land use patterns (agriculture and livestock), microbial pollution, inadequate sanitation systems, access to water of poor quality, and lack of institutional support are common problems which disproportionally affect poor and vulnerable people. This research aims at developing a system dynamic model to improve the understanding of the macro and micro factors that influence human health and environmental health in rural micro-catchments in Valle del Cauca, Colombia. In this catchment livelihoods for most people depend on agriculture, particularly coffee. The research uses a mediated modeling approach, in which different stakeholders in modeling sessions, develop a STELLA model that allows them to identify relations between the economic, social and environmental factors and driving forces over the performance of their system. Stakeholders jointly develop the model structure in sessions facilitated by the researcher and the data required is gathered using secondary information from the different relevant institutions and primary information from field surveys that cover socioeconomic and environmental aspects that has not been previously collected by any institution or organization (i.e. household survey, stream water survey, and drinking water survey). Representation and understanding of their system will allow the stakeholders to test the effect of different management strategies in the micro-catchment and their associated socioeconomic, environmental and human health outcomes.

2004-10-01

The Circum-Pacific, and particularly the Central and South America, subduction zones are complex structures that are subject to frequent, large-magnitude earthquakes, volcanic activity, tsunamis, and geological hazards. Among these natural hazards, earthquakes produce the most significant social and economic impacts in Latin America, and the subduction zones therefore demand constant vigilance and intensive study. The American continent has witnessed serveral earthquakes that rank among the most destrive in the world. Earthquakes such as the ones that occurred in Colombia-Ecuador [Mw = 8.9, 1906], Chile [Mw = 9.6, 1960; Mw = 8.9, 1995], Mexico [Mw = 9.6, 1985], and Peru [Mw = 8.0, 2001], as well as a number of destuctive events related to crustal fault systems and volcanic eruptions [e.g., Soufrière, El Ruiz, Galeras, ect.], have produced significant human and economic loss.The latent seismic hazards in the Caribbean, and Central and South America demand from the regional Earth sciences community accurate models to explain the mechanisms of these natural phenomena.

Reassessment of Colombia's tropical glaciers retreat rates: are they bound to disappear during the 2010-2020 decade?

NASA Astrophysics Data System (ADS)

Poveda, G.; Pineda, K.

2009-12-01

Clear-cut evidences of global environmental change in Colombia are discussed for diverse hydro-climatic records, and illustrated herein for increasing minimum temperature and decreasing annual maximum river flows records. As a consequence, eight tropical glaciers disappeared from the Colombian Andes during the 20th century, and the remaining six have experienced alarming retreat rates during the last decade. Here we report an updated estimation of retreat rates in the six remaining glacierized mountain ranges of Colombia for the period 1987-2007, using Landsat TM and TM+ imagery. Analyses are performed using detailed pre-processing, processing and post-processing satellite imagery techniques. Alarming retreat rates are confirmed in the studied glaciers, with an overall area shrinkage from 60 km2 in 2002, to 55.4 km2 in 2003, to less than 45 km2 in 2007. Assuming such linear loss rate (~3 km2 per year), for the near and medium term, the total collapse of the Colombian glaciers can be foreseen by 2022, but diverse physical mechanisms discussed herein would exacerbate the shrinkage processes, thus prompting us to forecast a much earlier deadline by the late 2010-2020 decade, long before the 100 years foreseen by the 2007 IPCC Fourth Assessment Report. This forecast demands detailed monitoring studies of mass and energy balances. Our updated estimations of Colombia's glacier retreat rates posse serious challenges for highly valuable ecosystem services, including water supply of several large cities and hundreds of rural settlements along the Colombian Andes, but also for cheap and renewable hydropower generation which provides 80% of Colombia's demand. Also, the identified changes threaten the survivability of unique and fragile ecosystems like paramos and cloud forests, in turn contributing to exacerbate social unrest and ongoing environmental problems in the tropical Andes which have been identified as the most critical hotspot for biodiversity on Earth.

Introduction Environmental factors contribute with 16% of the burden of disease in Colombia. A main obstacle in implementing national and regional environmental and occupational health policies is the limited knowledge on the local ability to study and control the impact of harmful exposures on health. Objective To identify needs for research and training in environmental and occupational health in Colombia. Materials and methods We conducted a three-round hybrid Delphi study. A group of environmental and occupational health Colombian experts (n=16) from government agencies, universities, and research centers was recruited to participate in the study. Expert’s opinions on research and training needs were gathered through online questionnaires, followed by an in-person meeting. The percentage of agreement and the coefficient of variation were used to measure consensus. Results Air pollution and chemical products were considered the most important environmental and occupational exposures, due to their significant impact on chronic non-communicable diseases, such as respiratory diseases, cardiovascular diseases, and cancer. Research on the effects of outdoor air pollution on cardiovascular and respiratory diseases was considered of the greatest importance. Priority training areas included environmental and occupational health risk assessment, exposure modeling, advanced statistical methods, urban planning, occupational safety and hygiene, and epidemiology and toxicology. Conclusions These findings provide a valuable input for the definition and implementation of national environmental and occupational health policies and for the development of a regional hub aimed at strengthening the capacity for research and training in Colombia.

Tropical dry forests (TDFs) have been defined as a single biome occurring mostly in the lowlands where there is a marked period of drought during the year. In the Neotropics, dry forests occur across contrasting biogeographical regions that contain high beta diversity and endemism, but also strong anthropogenic pressures that threaten their biodiversity and ecological integrity. In Colombia, TDFs occur across six regions with contrasting soils, climate, and anthropogenic pressures, therefore being ideal for studying how these variables relate to dry forest species composition, successional stage and conservation status. Here, we explore the variation in climate and soil conditions, floristic composition, forest fragment size and shape, successional stage and anthropogenic pressures in 571 dry forest fragments across Colombia. We found that TDFs should not be classified solely on rainfall seasonality, as high variation in precipitation and temperature were correlated with soil characteristics. In fact, based on environmental factors and floristic composition, the dry forests of Colombia are clustered in three distinctive groups, with high species turnover across and within regions, as reported for other TDF regions of the Neotropics. Widely distributed TDF species were found to be generalists favored by forest disturbance and the early successional stages of dry forests. On the other hand, TDF fragments were not only small in size, but highly irregular in shape in all regions, and comprising mostly early and intermediate successional stages, with very little mature forest left at the national level. At all sites, we detected at least seven anthropogenic disturbances with agriculture, cattle ranching and human infrastructure being the most pressing disturbances throughout the country. Thus, although environmental factors and floristic composition of dry forests vary across regions at the national level, dry forests are equally threatened by deforestation, degradation

DEL red blood cells (RBCs) type as D- by routine serologic methods and are transfused routinely, without being identified as expressing a very weak D antigen, to D- recipients. DEL RBCs are detected only by adsorption and elution of anti-D or by molecular methods. Most DEL phenotypes have been reported in population studies conducted in East Asia, although DEL phenotypes have been detected also among Caucasian individuals. Approximately 98 percent of DEL phenotypes in East Asians are associated with the RHD*DEL1 or RHD*01EL.01 allele. The prevalence of DEL phenotypes has been reported among D- Han Chinese (30%), Japanese (28%), and Korean (17%) populations. The prevalence of DEL phenotypes is significantly lower among D- Caucasian populations (0.1%). Among the 3-5 percent of African individuals who are D-, there are no reports of the DEL phenotype. Case reports from East Asia indicate that transfusion of DEL RBCs to D- recipients has been associated with D alloimmunization. East Asian immigrants constitute 2.1 percent of the 318.9 million persons residing in the United States, and an estimated 2.8 percent are blood donors. Using these statistics, we estimate that 68-683 units of DEL RBCs from donors of East Asian ancestry are transfused as D- annually in the United States. Given the reports from East Asia of D alloimmunization attributed to transfusion of DEL RBCs, one would expect an occasional report of D alloimmunization in the United States following transfusion of DEL RBCs to a D- recipient. If such cases do occur, the most likely reason that they are not detected is the absence of active post-transfusion monitoring for formation of anti-D.

Without ongoing surveillance systems to assess tobacco product demand and exposure levels, many low and middle income countries monitor smoking via periodic cross-sectional surveys. In this article, we seek to update estimates for the prevalence of adult smoking in Colombia and contribute additional information useful for tobacco control initiatives. Data are from the 2003 Colombian National Study of Mental Health (NSMH). A national probability sample of 4,426 adults (age 18-65) was assessed via a computer-assisted interview. An estimated 49% of the adult population had smoked at least once in their lifetimes; one in three adults (31%) had smoked regularly. Nearly half of regular smokers had been able to quit (44%; 95% CI= 40-48). Several personal and smoking related characteristics were associated with failing to quit: being a younger age, employed as compared to being a homemaker, and a history of daily use. Quitters and non-quitters were equivalent with respect to sex, educational status, and age of smoking onset. In conclusion, our findings describe the characteristics of regular smokers in Colombia and identify subgroups of non-quitters that may help guide tobacco control activities. PMID:18006241

2007-10-22

Fourteen years after the reform to Colombia's health system, the promises of universality, improved equity, efficiency, and better quality of care have not materialized. Remote areas remain underserved and access to care very limited. Recognizing teleconsultation as an effective way to improve access to health care and health information, a noncommercial open-access Web-based application for teleconsultation called Doctor Chat was developed. The objective was to report the experience of the Center for Virtual Education and Simulation eHealth (Centro de Educación Virtual y Simulación e-Salud) with open-access Web-based asynchronous teleconsultation for consumers in Colombia. A teleconsultation service in Spanish was developed and implemented in 2006. Teleconsultation requests were classified on three axes: (1) the purpose of the query, (2) the specialty, and (3) the geographic area of the query. Content analysis was performed on the free-text queries submitted to Doctor Chat, and descriptive statistics were gathered for each of the data categories (name, email, city, country, age, and gender). From September 2006 to March 2007, there were 270 asynchronous teleconsultations documented from 102 (37.8%) men and 168 (62.2%) women. On average, 1.4 requests were received per day. By age group, the largest number of requests (n = 80; 30%) were from users 24-29 years, followed by users (n = 66; 24%) 18-23 years. Requests were mainly from Colombia (n = 204; 75.6%) but also from Spain (n = 17; 6.3%), Mexico (n = 11; 4.1%), and other countries. In Colombia, 137 requests (67.2%) originated in Bogotá, the nation's capital, 25 (12.4%) from other main cities of the country, 40 (19.7%) from intermediate cities, and 2 (0.7%) from remote areas. The purpose of the majority of requests was for information about symptoms, health-related problems, or diseases (n = 149; 55.2%) and medications/treatments (n = 70; 25.9%). By specialty, information was most requested for gynecology and

In malaria-endemic regions of Latin America, little is known about malaria in pregnancy. To characterize the clinical and laboratory findings of maternal infection, we evaluated 166 cases of pregnant women infected with Plasmodium spp. in a prospective study conducted in northwestern Colombia during 2005–2006. A total of 89.8% (149 of 166) had fever or a history of fever in the past 48 hours, 9.0% (15 of 166) had severe malaria, of which 66.7% was caused by Plasmodium vivax and 33.3% by P. falciparum. Hepatic dysfunction was the main complication (9 of 15) observed. The proportion of severe cases was similar for both species (P = 0.41). In malaria-endemic areas of Colombia, malaria in pregnancy has a broad clinical spectrum. In pregnant women, P. vivax infection frequently leads to organ-specific complications. PMID:23897991

The prevalence of cervical intraepithelial neoplasia (CIN) and the association of CIN with prostitution was examined in Oviedo, a region in Spain with low incidence of cervical cancer, and in Cali, Colombia, where the incidence of cervical cancer is 6-10 times higher. In Oviedo, the study included 758 prostitutes attending a sexually transmitted diseases clinic and 1203 nonprostitutes attending a family-planning clinic. In Cali, 775 prostitutes and 1795 nonprostitutes attending health centers were included. Seropositivity to common sexually transmitted agents was investigated in Spanish prostitutes. No significant difference was found in the prevalence of CIN between Oviedo and Cali in both prostitutes (2.5 versus 1.8%) and nonprostitutes (1.2 versus 1.1%). Prostitutes had a 2-fold increased risk of CIN as compared to nonprostitutes; in Spain, the prevalence odds ratio (POR) was 2.3 and the 95% confidence interval (CI) was 1.1-4.5, and, in Colombia, POR was 1.8 and the 95% CI was 0.9-3.5. Among prostitutes in Oviedo, human immunodeficiency virus (HIV) prevalence was 4.9% and HIV-positive prostitutes showed a high risk of CIN as compared to HIV-negative prostitutes (POR, 12.7; 95% CI, 3.9-40.9); 76% of HIV-positive prostitutes were i.v. drug users and showed an increased seroprevalence of other sexually transmitted diseases. HIV-negative prostitutes did not show any increased risk of CIN (POR, 1.2; 95% CI, 0.5-2.8). These results show that among nonprostitutes the prevalence of CIN was not statistically different between the two cities in Spain and Colombia; prostitutes were at moderate increased risk compared to nonprostitutes in both cities.(ABSTRACT TRUNCATED AT 250 WORDS)

Three of the seven species that comprise the pia series of the Lutzomyia verrucarum group have been recorded in Colombia, including L. pia, L. limafalcaoae and L. emberai. The aim of this paper is to report the occurrence of an anthropophilic morphospecies of the pia series in the country. Sand flies were collected with a mouth aspirator on protected human bait in a secondary forest in the municipality of Envigado, department of Antioquia. The entomological survey was performed from 18:00 to 22:00 hours in June and December, 2004. Captured specimens were identified as L. tihuiliensis, which can be distinguished easily from other species of the pia series by its basally pigmented pleura, the length of the labro-epipharynx, (3)350 microm, and the length of the second palpomere, (3)170 microm. In addition to the previous characters, the sand flies collected exhibit a longer common sperm duct than the individual ducts with the ratio of the lengths of the common/individual ducts (3)2. The finding of L. tihuiliensis raises to 21 the number of species of the Lutzomyia verrucarum group recorded to date in Colombia, including two endemic species of the pia series. From a biogeographical point of view, the presence of four species of the pia series in Colombia is of great interest for the study of the origin of the taxon.

Rickettsioses caused by Rickettsia felis are an emergent global threat. Historically, the northern region of the province of Caldas in Colombia has reported murine typhus cases, and recently, serological studies confirmed high seroprevalence for both R. felis and R. typhi. In the present study, fleas from seven municipalities were collected from dogs, cats, and mice. DNA was extracted and amplified by polymerase chain reaction (PCR) to identify gltA, ompB, and 17kD genes. Positive samples were sequenced to identify the species of Rickettsia. Of 1,341 fleas, Ctenocephalides felis was the most prevalent (76.7%). Positive PCR results in the three genes were evidenced in C. felis (minimum infection rates; 5.3%), C. canis (9.2%), and Pulex irritans (10.0%). Basic Local Alignment Search Tool (BLAST) analyses of sequences showed high identity values (> 98%) with R. felis, and all were highly related by phylogenetic analyses. This work shows the first detection of R. felis in fleas collected from animals in Colombia. PMID:23878183

Land Degradation needs biophysical and socioeconomic research approaches to understand the processes that alter the natural ecosystems by the human societies. Both approaches are relevant also to achieve the development of the societies and reach the sustainability of the land management (Escadafal et al., 2015; Jafari and Bakhshandehmehr, 2016). The opinion of the citizens, their perception of the land degradation and the chances we have to built more sustainable management and societies is less researched than other topics such as soil erosion, climate change, water contamination or lost of biodiversity (Francos et al., 2016; Keesstra et al., 2016; Martínez Murilloet al., 2016; Muñoz Rojas et al., 2016; Ruiz-Fernández et al, 2016; ). Forest fires are part of the Earth System since the plant colonization of the continents, fire is present in all the human societies and fire contributed to shape ecosystems. However, a negative opinion about the fire is found in many modern societies (Marques et al., 2015; Assefa and Hans-Rudolf, 2016; Orchard et al., 2016; Pereira et al., 2016). Forest fires are not a new issue in the Mediterranean due to the traditional use for grazing, agriculture or hunting, but the wildfires are generalized since the abandonment of the land in the last century. The lost of rural population and the mechanisation resulted in a vegetation recovery that triggered large wildfires in the whole North Mediterranean since the 1970´s. The perception of the forest fires by the citizens is very negative in El Massís del Caroig. Since 2012 until 2015 a questionnaire was applied to 188 stakeholders in the region and the results demonstrate that the prescribed fires are negative for any group of the society and they reject the use of prescribed fires. Fire is seen as a problem.

Aquatic Ecological Index based on freshwater (ICE(RN-MAE)) for the Rio Negro watershed, Colombia. Available indices to assess the ecological status of rivers in Colombia are mostly based on subjective hypotheses about macroinvertebrate tolerance to pollution, which have important limitations. Here we present the application of a method to establish an index of ecological quality for lotic systems in Colombia. The index, based on macroinvertebrate abundance and physicochemical variables, was developed as an alternative to the BMWP-Col index. The method consists on determining an environmental gradient from correlations between physicochemical variables and abundance. The scores obtained in each sampling point are used in a standardized correlation for a model of weighted averages (WA). In the WA model abundances are also weighted to estimate the optimum and tolerance values of each taxon; using this information we estimated the index of ecological quality based also on macroinvertebrate (ICE(RN-MAE)) abundance in each sampling site. Subsequently, we classified all sites using the index and concentrations of total phosphorus (TP) in a cluster analysis. Using TP and ICE(RN-MAE), mean, maximum, minimum and standard deviation, we defined threshold values corresponding to three categories of ecological status: good, fair and critical.

Active school transport (AST) is a recommended strategy to promote physical activity (PA) and prevent overweight (OW) in school-aged children. In many developing countries, such as Colombia, this association has not been well characterized. To determine the association between AST and weight status in a representative sample of adolescents from Montería, Colombia. Participants were 546 adolescents (278 boys) aged 11 to 18 years old from 14 randomly selected schools in Montería, Colombia in 2008. The PA module of the Global School Health Survey (GSHS-2007) was used to determine the prevalence of AST. To identify OW, participants were classified according to CDC 2000 criteria (BMI ≥ 85th percentile). Association between AST and OW was determined by binomial logistic regression. Odds ratios adjusted for age, sex, location of school, compliance with PA, and screen time recommendations showed that adolescents who reported AST had a significantly lower likelihood to be OW compared with adolescents who reported nonactive transportation (OR = 0.5, 95% CI 0.3-0.8, P < .05). These results support the importance of AST as a useful PA domain with potential implications for overweight prevention, in rapidly developing settings. Further epidemiologic and intervention studies addressing AST are needed in the region.

2015-03-05

To analyze trends in mortality in Argentina, Chile, Colombia and Mexico, between 2000 and 2011, by sex and 5-year age groups (between 20 and 79 years of age). Mortality vital statistics and census data or projected population estimates were used for each country. Age-specific mortality rates and the years of life lost were calculated. Among the countries analyzed, Mexico had the highest mortality rate and lost the most years of life due to diabetes. Between 2000 and 2011, Mexicans lost an average of 1.13 years of life, while Colombia (0.24), Argentina (0.21) and Chile (0.18) lost considerably fewer life years. In general, deaths from diabetes were higher in men than in women except in Colombia. Nearly 80% of years of life lost due to diabetes occurred between 50 and 74 years of age in the four countries. Diabetes is a huge challenge for Latin America, especially in Mexico where mortality due to diabetes is accelerating. Even though the proportion of deaths due to diabetes in Argentina, Chile and Colombia is smaller, this disease figures among the main causes of death in these countries. Copyright © 2014 SESPAS.

Transmission of Zika virus (ZIKV) was first detected in Colombia in September 2015. As of April 2016, Colombia had reported over 65,000 cases of Zika virus disease (ZVD). We analysed daily surveillance data of ZVD cases reported to the health authorities of San Andres and Girardot, Colombia, between September 2015 and January 2016. ZVD was laboratory-confirmed by reverse transcription-polymerase chain reaction (RT-PCR) in the serum of acute cases within five days of symptom onset. We use daily incidence data to estimate the basic reproductive number (R0) in each population. We identified 928 and 1,936 reported ZVD cases from San Andres and Girardot, respectively. The overall attack rate for reported ZVD was 12.13 cases per 1,000 residents of San Andres and 18.43 cases per 1,000 residents of Girardot. Attack rates were significantly higher in females in both municipalities (p < 0.001). Cases occurred in all age groups with highest rates in 20 to 49 year-olds. The estimated R0 for the Zika outbreak was 1.41 (95% confidence interval (CI): 1.15–1.74) in San Andres and 4.61 (95% CI: 4.11–5.16) in Girardot. Transmission of ZIKV is ongoing in the Americas. The estimated R0 from Colombia supports the observed rapid spread. PMID:27452806

Climatic Forcing on Black Sigatoka Disease of Banana Crops in Urabá, Colombia

Bananas are widely the most consumed fruit in the world and Colombia is one of the major producers and exporters of bananas worldwide. We analyzed the climatic forcing agents on banana crops in the Urabá region, the largest banana producer in Colombia. Although this crop is harvested continuously throughout the entire year, it exhibits climate driven seasonality. Black Sigatoka Disease (BSD) has been the most important threat for banana production worldwide. BSD attacks plant leaves producing small spots of dead material. When BSD is not treated, it can grow enough to damage the entire leaf, reducing both growth and developmental rates which may result in the loss of the plant. BSD is caused by Mycosphaerella fijiensis. This fungus is dispersed by wind with its inoculation occurring when there is water on the leaf. Thus, climatic variables such as wind, relative humidity of air (RH) and leaf wetness duration (LWD) all affect phenological phases of the banana crop (suckering, growing, flowering and harvesting). This study was carried out at the Cenibanano Experimental Plot located in Carepa (Urabá, Colombia) during 2007-2012. We used phytopathologic and weather data from the Cenibanano database along with climatic data from the North American Regional Reanalysis (NARR). BSD was diagnosed using the Biological Forecasting method. Results show that rainfall drives both plant and disease development rate. During wet periods the Foliar Emission Rate exceeds rates measured during dry periods. Although wetness is a positive factor for fungal reproduction (and BSD), it also heightens the chance for the plant to create more foliar tissue to fight against BSD. Hence, during wet periods the Severity Index of BSD is reduced in relation to dry periods. This effect was also observed at the inter-annual scale of the El Niño - South Oscillation (ENSO) phenomenon. During the ENSO warm/cold phase (El Niño/La Niña) rainfall anomalies in Colombia were observed as negative

It focuses on those urban-emanating forces that provide rural people with a perspective of 'city' life. The impact of such things as the construction (or improvement) of roads, the role of the media, return visits by ex-villagers, and the urban visiting of country people [is] discussed in terms of social urbanization. This presentation renews the call for eschewing bipolar models for studying migration/urbanization in favor of a broader and more holistic perspective.

Human behavior plays a key role in the dynamics of dengue transmission. However, research on the relationship between human movement and dengue transmission within endemic countries is limited. From January 2008 to December 2011, the authors of this study conducted a retrospective analysis of imported dengue infections in Bogotá, Colombia. Bogotá is a vector-transmission-free city that is also the capital district and most populated municipality in Colombia. The study revealed that 1) Bogotá inhabitants acquired dengue infection in diverse localities throughout the country but the largest proportion of cases (35.6%) were contracted at popular tourist destinations in dengue-endemic areas near Bogotá (<200-km radius from city limits), and 2) the number of imported dengue cases increased after major holidays, a transmission pattern not seen in dengue-endemic areas, where disease incidence correlates with rainy periods. It is therefore recommended that physicians consider the effect of travel when diagnosing their patients' illnesses, especially outside dengue-endemic areas where diagnosis of the disease can be challenging due to its nonspecific symptoms. The study also showed that analysis of dengue cases imported to regions free of vector transmission can generate an evidence-based model for characterizing the impact of human movement on the spread of diseases like dengue in countries where they are endemic.

Yellow fever is a neglected tropical disease, thus, knowing the trends in mortality from this disease in Colombia is an important source of information for decision making and identifying public health interventions. To analyze trends in yellow fever mortality in Colombia during the 1998-2009 period and the differences in the morbidity and mortality information sources for the country, which affect indicators such as the lethality one. This is a descriptive study of deaths by yellow fever according to the Departamento Administrativo Nacional de Estadística and the incidence of the disease according to the Instituto Nacional de Salud . We used secondary sources of information in the calculation of proportions of socio-demographic characteristics of the deceased and epidemiological measures of lethality, incidence and mortality from yellow fever by department of residence of the deceased. Yellow fever deaths occur primarily in men of working age residing in scattered rural areas, who were members of the regimen vinculado, and who were living in the eastern, southeastern, northern and central zones in the country. We observed inconsistencies in the reports that affect the comparative analysis. The inhabitants of the departments located in national territories and Norte de Santander have an increased risk of illness and death from yellow fever, but this information could be underestimated, according to the source of information used for its calculation.

The medication is dispensed by the company Audifarma S.A. to hospitals and clinics around Colombia. Data were classified according to the taxonomy of the National Coordinating Council for Medication Error Reporting and Prevention (NCC MERP). The data analysis was performed using SPSS 22.0 for Windows, considering p-values < 0.05 significant. there were 9 062 medication errors in 45 hospital pharmacies. Real errors accounted for 51.9% (n = 4 707), of which 12.0% (n = 567) reached the patient (Categories C to I) and caused harm (Categories E to I) to 17 subjects (0.36%). The main process involved in errors that occurred (categories B to I) was prescription (n = 1 758, 37.3%), followed by dispensation (n = 1 737, 36.9%), transcription (n = 970, 20.6%) and administration (n = 242, 5.1%). The errors in the administration process were 45.2 times more likely to reach the patient (CI 95%: 20.2-100.9). medication error reporting systems and prevention strategies should be widespread in hospital settings, prioritizing efforts to address the administration process.

Objective: This study sought to measure burden of disease and identifies health priorities from the Disability Adjusted Life Years (DALYs) indicator. Methods: This is the first study on burden of disease for a department in Colombia by using a standardized methodology. By using the DALYs indicator, burden of disease was identified in the department of Nariño according to the guidelines established by the World Health Organization. Results: The DALYs in the Department of Nariño highlight the emergence of communicable, maternal, perinatal, and nutritional diseases during the first years of life; of accidents and lesions among youth, and non-communicable diseases in older individuals. Also, accidents and lesions are highlighted in men and non-communicable diseases in women. Conclusions: This study is part of the knowledge management process in the Departmental Health Plan for Nariño - Colombia 2012-2015 and contributes to the system of indicators of the 2012 ten-year public health plan. This research evidences that communicable diseases generate the biggest part of the burden of disease in the Department of Nariño, that DALYs due to non-communicable diseases are on the rise, and that accidents and lesions, especially due to violence are an important cause of DALYs in this region, which is higher than that of the country.

Triatoma dimidiata (Hemiptera: Reduviidae) is a secondary vector of Trypanosoma cruzi in Colombia and represents an important epidemiological risk mainly in the central and oriental regions of the country where it occupies sylvatic, peridomestic, and intradomestic ecotopes, and because of this complex distribution, its distribution and abundance could be conditioned by environmental factors. In this work, we explored the relationship between T. dimidiata distribution and environmental factors in the northwest, northeast, and central zones of Colombia and developed predictive models of infestation in the country. The associations between the presence ofT. dimidiata and environmental variables were studied using logistic regression models and ecological niche modeling for a sample of villages in Colombia. The analysis was based on the information collected in field about the presence ofT. dimidiata and the environmental data for each village extracted from remote sensing images. The presence of Triatoma dimidiata(Latreille, 1811) was found to be significantly associated with the maximum vegetation index, minimum land surface temperature (LST), and the digital elevation for the statistical model. Temperature seasonality, annual precipitation, and vegetation index were the variables that most influenced the ecological niche model ofT. dimidiata distribution. The logistic regression model showed a good fit and predicted suitable habitats in the Andean and Caribbean regions, which agrees with the known distribution of the species, but predicted suitable habitats in the Pacific and Orinoco regions proposing new areas of research. Improved models to predict suitable habitats forT. dimidiata hold promise for spatial targeting of integrated vector management. © The American Society of Tropical Medicine and Hygiene.

[Paper on sterilization in the family planning programs of Colombia: a national debate].

PubMed

Rizo, A; Roper, L

1986-01-01

During 1984, family planning became the object of heated public debate in Colombia. In particular, considerable controversy surrounded the practice of sterilization. In Colombia in 1980, 49% of married women were practicing family planning. The main protagonist has been Profamilia, an IPPF affliate, which runs clinics and advisory services throughout Colombia. Sterilization is performed quite extensively on men of at least 28 years and women of 25 with 3 living children. Further activities of Profamilia include community distribution and social marketing programs. Many of the health facilities used are those of the Ministry of Public Health. The Minister of Health responded to criticism levelled by the Catholic church and others by instituting an investigation into alleged practices of mass sterilization. Profamilia declared publicy that sterilization was performed only under certain conditions, after waiting periods, and under no circumstances with coersion. Various groups including medical associations publicy supported Profamilia. Although recognizing the need for families to be limited in size, religious and other commentators suggested that sterilization was often presented as a solution to family ills, and that it represented foreign involvement in Colombian social policy. The opposing opinions were that church-supported natural family planning was not an effective enough strategy. The ministry has resolved to invoke more stringent screening of women desiring sterilization to include natural family planning in its programs, and to deal with international organizations only on the ministry level. The number of sterilizations has diminished. The controversy helped to expose political weaknesses of Profamilia's programs (e.g. the use of monetary incentives; lack of supervision).

To estimate economic impact resulting from increased biologics use for treatment of rheumatoid arthritis (RA) and Crohn's disease (CD) in Argentina, Brazil, Colombia, and Mexico. The influence of increasing biologics use for treatment of RA during 2012-2022 and for treatment of CD during 2013-2023 was modeled from a societal perspective. The economic model incorporated current and projected medical, indirect, and drug costs and epidemiologic and economic factors. Costs associated with expanded biologics use for RA were compared with non-expanded use in Argentina, Brazil, Colombia, and Mexico. A similar analysis was conducted for CD in Brazil, Colombia, and Mexico. Accounting for additional costs of biologics and medical and indirect cost offsets, the model predicts that expanded use of biologics for patients with RA from 2012 to 2022 will result in cumulative net cost savings of ARS$2.351 billion in Argentina, R$9.004 billion in Brazil, COP$728.577 billion in Colombia, and MXN$18.02 billion in Mexico; expanded use of biologics for patients with CD from 2013 to 2023 will result in cumulative net cost savings for patients with CD of R$0.082 billion in Brazil, COP$502.74 billion in Colombia, and MXN$1.80 billion in Mexico. Indirect cost offsets associated with expanded biologics use were a key driver in reducing annual per-patient net costs for RA and CD. Future economic projections are limited by the potential variance between projected and actual future values of biologic prices, wages, medical costs, and gross national product for each country. Increasing biologics use to treat RA and CD may limit cost growth over time by reducing medical and indirect costs. These findings may inform policy decisions regarding biologics use in Argentina, Brazil, Colombia, and Mexico.

Colombia (South America) has six small glaciers (total glacierized area of 45 Km2); their geographical location, close to zero latitude, makes them very sensitive to climate changes. An extensive monitoring program is being performed since 2006 on two glaciers, with international cooperation supports. This presentation summarizes the results of glacier changes in Colombia and includes the latest results obtained within the CATCOS Project - Phase 1 (Capacity Building and Twinning for Climate Observing Systems) signed between Colombia and Switzerland, and within the Joint Mixte Laboratory GREAT-ICE (IRD - France), with the application of LiDAR technology and GPR-based ice thickness measurements at Conejeras Glacier. Conejeras Glacier (Lat. N. 4° 48' 56"; Long. W. 75° 22' 22"; Alt. Max. 4915m.; Alt. Min. 4730m. Area 0.2 Km2) is located on the north-western side of Santa Isabel Volcano. This glacier belongs to global glacier monitoring network of the World Glacier Monitoring Service (WGMS-ID: 2721). The surface mass balance is calculated monthly using the direct glaciological method. Between April 2006 and May 2014, Conejeras Glacier showed a cumulative loss of -21 m w.e. The CATCOS Project allowed to improve the glacier monitoring system in Colombia with two main actions: (1) a terrestrial laser scanner survey (RIEGL VZ-6000 terrestrial laser scanner, property of Universities of Lausanne and Fribourg); and (2) ice thickness measurements (Blue System Integration Ltd. Ice Penetrating Radar of property of IRD). The terrestrial laser-scanning survey allowed to realize an accurate digital terrain model of the glacier surface with 13 million points and a decimetric resolution. Ice thickness measurements showed an average glacier thickness of 22 meters and a maximum of 52 meters.

High genetic structure and low mitochondrial diversity in bottlenose dolphins of the Archipelago of Bocas del Toro, Panama: A population at risk?

The current conservation status of the bottlenose dolphin (Tursiops truncatus) under the IUCN is ‘least concern’. However, in the Caribbean, small and localized populations of the ‘inshore form’ may be at higher risk of extinction than the ‘worldwide distributed form’ due to a combination of factors including small population size, high site fidelity, genetic isolation, and range overlap with human activities. Here, we study the population genetic structure of bottlenose dolphins from the Archipelago of Bocas del Toro in Panama. This is a small population characterized by high site fidelity and is currently heavily-impacted by the local dolphin-watching industry. We collected skin tissue samples from 25 dolphins to study the genetic diversity and structure of this population. We amplified a portion of the mitochondrial Control Region (mtDNA-CR) and nine microsatellite loci. The mtDNA-CR analyses revealed that dolphins in Bocas del Toro belong to the ‘inshore form’, grouped with the Bahamas-Colombia-Cuba-Mexico population unit. They also possess a unique haplotype new for the Caribbean. The microsatellite data indicated that the Bocas del Toro dolphin population is highly structured, likely due to restricted movement patterns. Previous abundance estimates obtained with mark-recapture methods reported a small population of 80 dolphins (95% CI = 72–87), which is similar to the contemporary effective population size estimated in this study (Ne = 73 individuals; CI = 18.0 - ∞; 0.05). The combination of small population size, high degree of genetic isolation, and intense daily interactions with dolphin-watching boats puts the Bocas del Toro dolphin to at high risk of extinction. Despite national guidelines to regulate the dolphin-watching industry in Bocas del Toro and ongoing educational programs for tour operators, only in 2012 seven animals have died due to boat collisions. Our results suggest that the conservation status of bottlenose dolphins in

Contending medical ideologies and state formation: the nineteenth-century origins of medical pluralism in contemporary Colombia.

PubMed

Sowell, David

2003-01-01

This article addresses the encounter between contending medical ideologies in nineteenth-century Colombia. The first era of medical pluralism, in colonial Latin America, developed from the imposition of Hispanic medicine on existing indigenous medical systems through an imperial structure. This produced a "colonial medical spectrum" incorporating various medical ideologies that came under attack by practitioners of scientific medicine in the 1800s. As scientific physicians gained privileged access to state resources, they undertook partially successful campaigns to deny Hispanic, homeopathic, and other medical systems the right to be practiced. As the state authorized scientific medicine, other practices became "popularized," thereby laying the foundation for the medical pluralism of contemporary Colombia that juxtaposes "academic" and "traditional" medicines.

A new species of small-eared shrew from Colombia and Venezuela (Mammalia: Soricomorpha: Soricidae: Genus Cryptotis)

USGS Publications Warehouse

Woodman, N.

2002-01-01

Populations of small-eared shrews inhabiting the northern Cordillera Oriental of Colombia and adjoining Venezuelan highlands in the vicinity of Paramo de Tama have been referred alternatively to Cryptotis thomssi or Cryptotis meridensis. Morphological and morphometrical study of this population indicates that it belongs to neither taxon, but represents a distinct, previously unrecognized species. I describe this new species as Cryptotis tamensis and redescribe C. meridensis. Recognition of the population at Paramo de Tama as a separate taxon calls into question the identities of populations of shrews currently represented only by single specimens from Cerro Pintado in the Sierra de Perija, Colombia, and near El Junquito in the coastal highlands of Venezuela.

Trends in reproductive behavior among young single women in Colombia and Peru: 1985-1999.

2003-11-01

Using "calendar" data for single women aged 15-24 from successive Demographic and Health Surveys (DHS) conducted in Colombia and Peru during the 1990s, we document trends, year by year, in sexual activity, the use of contraceptives, and subsequent reproductive outcomes. We provide evidence of the important and hitherto largely untapped potential of DHS calendar data to draw complete sexual and reproductive profiles when data from various surveys are integrated. Over the period 1985-1999, young single women in both Colombia and Peru became sexually active at younger ages. The use of contraceptives, especially the use of condoms, increased but did not fully offset the rise in sexual activity, and thus the incidence of premarital conceptions rose among young single women. In both countries, sharp declines occurred in the proportion of premaritally conceived births that were reported as being wanted.

Preliminary bioelectrical impedance analysis (BIA) equation for body composition assessment in young females from Colombia

A previous study showed that reported BIA equations for body composition are not suitable for Colombian population. The purpose of this study was to develop and validate a preliminary BIA equation for body composition assessment in young females from Colombia, using hydrodensitometry as reference method. A sample of 30 young females was evaluated. Inclusion and exclusion criteria were defined to minimize the variability of BIA. Height, weight, BIA, residual lung volume (RV) and underwater weight (UWW) were measured. A preliminary BIA equation was developed (r2 = 0.72, SEE = 2.48 kg) by stepwise multiple regression with fat-free mass (FFM) as dependent variable and weight, height and impedance measurements as independent variables. The quality of regression was evaluated and a cross-validation against 50% of sample confirmed that results obtained with the preliminary BIA equation is interchangeable with results obtained with hydrodensitometry (r2 = 0.84, SEE = 2.62 kg). The preliminary BIA equation can be used for body composition assessment in young females from Colombia until a definitive equation is developed. The next step will be increasing the sample, including a second reference method, as deuterium oxide dilution (D2O), and using multi-frequency BIA (MF-BIA). It would also be desirable to develop equations for males and other ethnic groups in Colombia.

Correlation between malaria incidence and prevalence of soil-transmitted helminths in Colombia: an ecologic evaluation.

Recent studies have suggested an association between the soil-transmitted helminth infections and malaria incidence. However, published evidence is still insufficient and diverging. Since 1977, new ecologic studies have not been carried out to explore this association. Ecologic studies could explore this correlation on a population level, assessing its potential importance on public health. The aim of this evaluation is to explore the association between soil-transmitted helminths prevalence and malaria incidence, at an ecologic level in Colombia. Using data from the National Health Survey, which was carried out in 1980 in Colombia, we calculated Spearman correlation coefficients between the prevalence of: Ascaris lumbricoides, Trichuris trichiura and hookworm, with the 1980 malaria incidence data of the same year provided from the Colombian Malaria National Eradication Service. A robust regression analysis with least trimmed squares was performed. Falciparum malaria incidence and Ascaris lumbricoides prevalence had a low correlation (R²= 0.086) but this correlation was stronger into the clusters of towns with prevalence of Ascaris lumbricoides infection above 30% were only included (R²= 0.916). This work showed an ecologic correlation in Colombia between malaria incidence and soil-transmitted helminths prevalence. This could suggest that either there is an association between these two groups of parasites, or could be explained by the presence of common structural determinants for both diseases.

We describe results of cooperative work that advanced volcanic monitoring and risk reduction. The USGS-USAID Volcano Disaster Assistance Program (VDAP) was initiated in 1986 after disastrous lahars during the 1985 eruption of Nevado del Ruiz dramatizedthe need to advance international capabilities in volcanic monitoring, eruption forecasting and hazard communication. For the past 28 years, VDAP has worked with our partners to improve observatories, strengthen monitoring networks, and train observatory personnel. We highlight a few of the many accomplishments by Latin American volcano observatories. Advances in monitoring, assessment and communication, and lessons learned from the lahars of the 1985 Nevado del Ruiz eruption and the 1994 Paez earthquake enabled the Servicio Geológico Colombiano to issue timely, life-saving warnings for 3 large syn-eruptive lahars at Nevado del Huila in 2007 and 2008. In Chile, the 2008 eruption of Chaitén prompted SERNAGEOMIN to complete a national volcanic vulnerability assessment that led to a major increase in volcano monitoring. Throughout Latin America improved seismic networks now telemeter data to observatories where the decades-long background rates and types of seismicity have been characterized at over 50 volcanoes. Standardization of the Earthworm data acquisition system has enabled data sharing across international boundaries, of paramount importance during both regional tectonic earthquakes and during volcanic crises when vulnerabilities cross international borders. Sharing of seismic forecasting methods led to the formation of the international organization of Latin American Volcano Seismologists (LAVAS). LAVAS courses and other VDAP training sessions have led to international sharing of methods to forecast eruptions through recognition of precursors and to reduce vulnerabilities from all volcano hazards (flows, falls, surges, gas) through hazard assessment, mapping and modeling.

2014-01-01

Characterizing and contrasting the current state of affairs concerning patients' rights-associated accreditation standards in a sample of drug-addiction treatment centers in Colombia. This was mixed methodology research (i.e. descriptive and hermeneutic); a pilot sample of 21 drug-addiction treatment centers in Colombia was used for determining the current state of patients' rights accreditation standards. The possible relationship or independence between categorical variables was evaluated by using Fisher's exact test (0.05 significance level). A contrasting documentary review was made at the same time. Drug-addiction treatment centers provided more information for families (95 %) than patients (90 %) or minors (81 %). Possible barriers to gaining access for treatment were being HIV positive (29 %), being part of the LGTB population (14 %) and being female (10 %); religion and ethnicity were not seen as grounds for discrimination or treatment barriers. The patients' rights standards group coincided with Colombia's accreditation system and Joint Commission standards; however, the latter accreditation entity has made significant progress regarding a specific manual for drug-addiction treatment centers. The centers assessed in Colombia had made advances regarding accrediting patients' rights, but such standards require revision for being adapted to international developments and specific matters involved in treating addicts and the specific conditions for institutions dealing with such treatment.

Malaria-Related Anemia in Patients from Unstable Transmission Areas in Colombia

Lopez-Perez, Mary; Álvarez, Álvaro; Gutierrez, Juan B.; Moreno, Alberto; Herrera, Sócrates; Arévalo-Herrera, Myriam

2015-01-01

Information about the prevalence of malarial anemia in areas of low-malaria transmission intensity, like Latin America, is scarce. To characterize the malaria-related anemia, we evaluated 929 malaria patients from three sites in Colombia during 2011–2013. Plasmodium vivax was found to be the most prevalent species in Tierralta (92%), whereas P. falciparum was predominant in Tumaco (84%) and Quibdó (70%). Although severe anemia (hemoglobin < 7 g/dL) was almost absent (0.3%), variable degrees of non-severe anemia were observed in 36.9% of patients. In Tierralta, hemoglobin levels were negatively associated with days of illness. Moreover, in Tierralta and Quibdó, the number of previous malaria episodes and hemoglobin levels were positively associated. Both Plasmodium species seem to have similar potential to induce malarial anemia with distinct cofactors at each endemic setting. The target age in these low-transmission settings seems shifting toward adolescents and young adults. In addition, previous malaria experience seems to induce protection against anemia development. Altogether, these data suggest that early diagnosis and prompt treatment are likely preventing more frequent and serious malaria-related anemia in Colombia. PMID:25510719

The objective of this research was to examine the association between income inequality and high blood pressure in Colombia. Using a nationally representative Colombian sample of adults, and data from departments and municipalities, we fit sex-stratified linear and logistic multilevel models with blood pressure as a continuous and binary variable, respectively. In adjusted models, women living in departments with the highest quintile of income inequality in 1997 had higher systolic blood pressure than their counterparts living in the lowest quintile of income inequality (mean difference 4.42mmHg; 95%CI: 1.46, 7.39). Women living in departments that were at the fourth and fifth quintile of income inequality in 1994 were more likely to have hypertension than those living in departments at the first quintile in the same year (OR: 1.56 and 1.48, respectively). For men, no associations of income inequality with either systolic blood pressure or hypertension were observed. Our findings are consistent with the hypothesis that income inequality is associated with increased risk of high blood pressure for women. Future studies to analyze pathways linking income inequality to high blood pressure in Colombia are needed.

Cancer incidence estimates at the national and district levels in Colombia.

PubMed

2006-01-01

To estimate national and district cancer incidence for 18 major cancer sites in Colombia. National and district incidence was estimated by applying a set of age, sex and site-specific incidence/mortality ratios, obtained from a population-based cancer registry, to national and regional mortality. The work was done in Bogotá (Colombia) and Lyon (France) between May 2003 and August 2004. The annual total number of cases expected (all cancers but skin) was 17 819 in men and 18 772 in women. Among males the most frequent cancers were those of the prostate (45.8 per 100 000), stomach (36.0), and lung (20.0). In females the most frequent were those of the cervix uteri (36.8 per 100 000), breast (30.0), and stomach (20.7). Districts with the lowest death certification coverage yielded the highest incidence rates. In the absence of national population-based cancer registry data, estimates of incidence provide valuable information at national and regional levels. As mortality data are an important source for the estimation,the quality of death certification should be considered as a possible cause of bias.

DNA barcoding for identifying synanthropic flesh flies (Diptera, Sarcophagidae) of Colombia.

The first step for a successful use of any insect as indicator in forensic sciences is providing a precise taxonomic identification at species level. Due to morphology-based identification of Sarcophaginae flies (Diptera, Sarcophagidae) is often difficult and requires strong taxonomic expertise, their use as forensic indicators has been limited. Consequently, molecular-based approaches have been accepted as alternative means of identification. Thus, we aimed testing the efficiency of the barcode region of the mitochondrial cytochrome oxidase subunit I (COI) gene for identification of synanthropic flesh flies of several species of the genera Peckia, Oxysarcodexia, Ravinia, and Tricharaea collected in Colombia. The 645-bp fragment of COI was amplified and aligned (215 parsimoniously informative variable sites). We calculated Kimura two-parameter genetic distances and reconstruct a Neighbor-Joining phylogenetic tree. Our Neighbor-Joining tree recovered all species as monophyletic, and confirmed a new species of the genus Ravinia as also indicated by the interspecific genetic divergences and morphological observations. We obtained a 100% of identification success. Thus, the COI barcodes showed efficiency as an alternative mean of identification of species of flesh flies collected on decaying organic matter in Colombia. Copyright © 2018 Elsevier B.V.

Until 2006, legal induced abortion was completely banned in Colombia. Few facilities are equipped or willing to offer abortion services; often adolescents experience even greater barriers of access in this context. We examined post abortion care (PAC) and legal induced abortion in two large public hospitals. We tested the association of hospital site, procedure type (manual vacuum aspiration vs. sharp curettage), and age (adolescents vs. women 20 years and over) with service type (PAC or legal induced abortion). Retrospective cohort study using 2010 billing data routinely collected for reimbursement (N=1353 procedures). We utilized descriptive statistics, multivariable logistic regression and predicted probabilities. Adolescents made up 22% of the overall sample (300/1353). Manual vacuum aspiration was used in one-third of cases (vs. sharp curettage). Adolescents had lower odds of documented PAC (vs. induced abortion) compared with women over age 20 (OR=0.42; 95% CI=0.21-0.86). The absolute difference of service type by age, however, is very small, controlling for hospital site and procedure type (.97 probability of PAC for adolescents compared with .99 for women 20 and over). Regardless of age, PAC via sharp curettage is the current standard in these two public hospitals. Both adolescents and women over 20 are in need of access to legal abortion services utilizing modern technologies in the public sector in Colombia. Documentation of abortion care is an essential first step to determining barriers to access and opportunities for quality improvement and better health outcomes for women. Following partial decriminalization of abortion in Colombia, in public hospitals nearly all abortion services are post-abortion care, not induced abortion. Sharp curettage is the dominant treatment for both adolescents and women over 20. Women seek care in the public sector for abortion, and must have access to safe, quality services. Copyright © 2014.

Poveda, E.; Monsalve, G.; Vargas-Jimenez, C. A.

2013-05-01

We have investigated crustal thickness beneath the Northern Andes with the teleseismic receiver function technique. We used teleseismic data recorded by an array of 18 broadband stations deployed by the Colombian Seismological Network, and operated by the Colombian Geological Survey. We used the primary P-to-S conversion and crustal reverberations to estimate crustal thickness and average Vp/Vs ratio; using Wadati diagrams, we also calculated the mean crustal Vp/Vs ratio around stations to further constrain the crustal thickness estimation. In northern Colombia, near the Caribbean coast, the estimated crustal thickness ranges from 25 to 30 km; in the Middle Magdalena Valley, crustal thickness is around 40 km; beneath the northern Central Cordillera, the Moho depth is nearly 40 km; at the Ecuador-Colombia border, beneath the western flank of the Andes, the estimated thickness is about 46 km. Receiver functions at a station at the craton in South East Colombia, near the foothills of the Eastern Cordillera, clearly indicate the presence of the Moho discontinuity at a depth near 36 km. The greatest values of crustal thickness occur beneath a plateau (Altiplano Cundiboyacense) on the Eastern Cordillera, near the location of Bogota, with values around 58 km. Receiver functions in the volcanic areas of the south-western Colombian Andes do not show a systematic signal from the Moho, indicating abrupt changes in Moho geometry. Signals at stations on the Eastern Cordillera near Bogota reveal a highly complex crustal structure, with a combination of sedimentary layers up to 9 km thick, dipping interfaces, low velocity layers, anisotropy and/or lateral heterogeneity that still remain to be evaluated. This complexity obeys to the location of these stations at a region of a highly deformed fold and thrust belt.

The lymphocytic choriomeningitis virus is an Old World arenavirus that infects Mus musculus, and can cause congenital hydrocephalus, chorioretinitis and multisystemic failure in transplant human recipients. Although the disease has not been clinically diagnosed in Colombia yet, there have been reports of infection with the Pichindé virus in rodents from Cauca and Valle del Cauca departments, and with the Guanarito virus in rodents from Córdoba department. To identify the lymphocytic choriomeningitis virus from Mus musculus captured in the municipality of Sincelejo. We evaluated 80 samples of plasma by ELISA using antigen from lymphocytic choriomeningitis virus. Additionally, a nested RT-PCR was performed to seropositive and seronegative samples for the S-segment. We found a 10% seroprevalence (8/80) and the viral genome was detected in 16 brain samples; the alignment (BLAST) and the phylogenetic analysis (MrBayes, version 3.2.2) confirmed the presence of the lymphocytic choriomeningitis virus. The results indicated that human infection with the lymphocytic choriomeningitis virus in humans could occur in the urban area of Sincelejo, although no cases have been reported so far.

This study evaluated primary care attributes of patient-centered care associated with the public perception of good quality in Brazil, Colombia, Mexico and El Salvador. We conducted a secondary data analysis of a Latin American survey on public perceptions and experiences with healthcare systems. The primary care attributes examined were access, coordination, provider-patient communication, provision of health-related information and emotional support. A double-weighted multiple Poisson regression with robust variance model was performed. The study included between 1500 and 1503 adults in each country. The results identified four significant gaps in the provision of primary care: not all respondents had a regular place of care or a regular primary care doctor (Brazil 35.7%, Colombia 28.4%, Mexico 22% and El Salvador 45.4%). The communication with the primary care clinic was difficult (Brazil 44.2%, Colombia 41.3%, Mexico 45.1% and El Salvador 56.7%). There was a lack of coordination of care (Brazil 78.4%, Colombia 52.3%, Mexico 48% and El Salvador 55.9%). Also, there was a lack of information about healthy diet (Brazil 21.7%, Colombia 32.9%, Mexico 16.9% and El Salvador 20.8%). The public's perception of good quality was variable (Brazil 67%, Colombia 71.1%, Mexico 79.6% and El Salvador 79.5%). The primary care attributes associated with the perception of good quality were a primary care provider 'who knows relevant information about a patient's medical history', 'solves most of the health problems', 'spends enough time with the patient', 'coordinates healthcare' and a 'primary care clinic that is easy to communicate with'. In conclusion, the public has a positive perception of the quality of primary care, although it has unfulfilled expectations; further efforts are necessary to improve the provision of patient-centered primary care services in these four Latin American countries. © The Author 2016.

The aim of this study was to investigate the characteristics and performance of transient evoked oto-acoustic emission (TEOAE) hearing screening in newborns in Colombia, and analyze all possible variables and factors affecting the results. An observational, descriptive and retrospective study with bivariate analysis was performed. The study population consisted of 56,822 newborns evaluated at the private institution, PREGEN. TEOAE testing was carried out as a pediatric hearing screening test from December 2003 to March 2012. The database from PREGEN was revised, and the protocol for evaluation included the same screening test performed twice. Demographic characteristics were recorded and the newborn's background was evaluated. Basic statistics of the qualitative and quantitative variables, and statistical analysis were obtained using the chi-square test. Of the 56,822 records examined, 0.28% were classed as abnormal, which corresponded to a prevalence of 1 in 350. In the screened newborns, 0.08% had a major abnormality or other clinical condition diagnosed, and 0.29% reported a family history of hearing loss. A prevalence of 6.7 in 10,000 was obtained for microtia, which is similar to the 6.4 in 10,000 previously reported in Colombia (database of the Latin-American Collaborative Study of Congenital Malformations - ECLAMC). Statistical analysis demonstrated an association between presenting with a major anomaly and a higher frequency of abnormal results on both TEOAE tests. Newborns in Colombia do not currently undergo screening for the early detection of hearing impairment. The results from this study suggest TEOAE screening tests, when performed twice, are able to detect hearing abnormalities in newborns. This highlights the need to improve the long-term evaluation and monitoring of patients in Colombia through diagnostic tests, and to provide tests that are both sensitive and specific. Furthermore, the use of TEOAE screening is justified by the favorable cost

Towards a community mental health care for people with schizophrenia in Colombia.

2016-08-01

Mental health care based on the community has shown to be effective and successful for the health care service to people with severe mental disorders such as schizophrenia, evidence that is less clear in the health care system in Colombia, where weaknesses are present, both for prevention and rehabilitation, although national guidelines give importance to the social context in relation to the disease. As a contribution to the discussion on providing care for people living with schizophrenia, a topic review was conducted with the aim of identifying experiences in community mental health care services, in relation to their relevance to these people at the national level. Articles were searched on Scientific Electronic Library Online (SciELO) Medline with Full text, Science Direct and documents of the World Health Organization, Pan American Health Organization and the Colombian Ministry of Health and Social Protection. Few experiences in community care for people with schizophrenia in Colombia were found and given its importance to public health worldwide, a call for attention is made towards the construction and implementation of these models in the Colombian context.

Aedes albopictus is widely distributed around the world. Its introduction to the Americas occurred in 1985 and it is considered a potential vector of dengue viruses and one of the principal vectors of chikungunya virus. In Colombia, this species was reported for the first time in Leticia (Amazonas) in 1998, followed by Buenaventura (Valle del Cauca) in 2001, Barrancabermeja (Santander) in 2010, and Medellín (Antioquia) in 2011. So far, this species has been reported in ten departments of the country. Objective: To report the finding of A. albopictus in the city of Istmina, Chocó, and its implications for public health. Materials and methods: In January 2015, we conducted an inspection of immature stages of Aedes spp. in breeding sites in the neighborhoods of San Agustín, Santa Genoveva and Subestación in Istmina, Chocó. The immature stages collected in this municipality were identified at the Unidad de Entomología of the Laboratorio de Salud Pública Departamental de Chocó, and confirmed by the Laboratorio de Entomología, Red Nacional de Laboratorios, Instituto Nacional de Salud, in Bogotá. In January 2015, twelve A. albopictus larvae were found in the breeding sites located in Subestación and San Agustín neighborhoods. The occurrence of A. albopictus in the municipality of Istmina underlines the importance of strengthening continuous entomological surveillance strategies at national and local levels in the country, especially in Istmina and its surrounding municipalities.

AIM: To examine the presence of human papillomavirus (HPV) in esophageal squamous cell carcinoma (ESCC) specimens collected from Colombia and Chile located in the northern and southern ends of the continent, respectively. METHODS: We examined 47 and 26 formalin-fixed and paraffin-embedded ESCC specimens from Colombia and Chile, respectively. HPV was detected using GP5+/GP6+ primer pair for PCR, and confirmed by Southern blot analysis. Sequencing analysis of L1 region fragment was used to identify HPV genotype. In addition, P16INK4A protein immunostaining of all the specimens was conducted. RESULTS: HPV was detected in 21 ESCC specimens (29%). Sequencing analysis of L1 region fragment identified HPV-16 genome in 6 Colombian cases (13%) and in 5 Chilean cases (19%). HPV-18 was detected in 10 cases (21%) in Colombia but not in any Chilean case. Since Chilean ESCC cases had a higher prevalence of HPV-16 (without statistical significance), but a significantly lower prevalence of HPV-18 than in Colombian cases (P = 0.011) even though the two countries have similar ESCC incidence rates, the frequency of HPV-related ESCC may not be strongly affected by risk factors affecting the incidence of ESCC. HPV-16 genome was more frequently detected in p16 positive carcinomas, although the difference was not statistically significant. HPV-18 detection rate did not show any association with p16 expression. Well-differentiated tumors tended to have either HPV-16 or HPV-18 but the association was not statistically significant. HPV genotypes other than HPV-16 or 18 were not detected in either country. CONCLUSION: HPV-16 and HPV-18 genotypes can be found in ESCC specimens collected from two South American countries. Further studies on the relationship between HPV-16 presence and p16 expression in ESCC would aid understanding of the mechanism underlying the presence of HPV in ESCC. PMID:17036393

Phylogenetic reconstruction of dengue virus type 2 in Colombia

PubMed Central

2012-01-01

Background Dengue fever is perhaps the most important viral re-emergent disease especially in tropical and sub-tropical countries, affecting about 50 million people around the world yearly. In Colombia, dengue virus was first detected in 1971 and still remains as a major public health issue. Although four viral serotypes have been recurrently identified, dengue virus type 2 (DENV-2) has been involved in the most important outbreaks during the last 20 years, including 2010 when the fatality rate highly increased. As there are no major studies reviewing virus origin and genotype distribution in this country, the present study attempts to reconstruct the phylogenetic history of DENV-2 using a sequence analysis from a 224 bp PCR-amplified product corresponding to the carboxyl terminus of the envelope (E) gene from 48 Colombian isolates. Results As expected, the oldest isolates belonged to the American genotype (subtype V), but the strains collected since 1990 represent the American/Asian genotype (subtype IIIb) as previously reported in different American countries. Interestingly, the introduction of this genotype coincides with the first report of dengue hemorrhagic fever in Colombia at the end of 1989 and the increase of cases during the next years. Conclusion After replacement of the American genotype, several lineages of American/Asian subtype have rapidly spread all over the country evolving in new clades. Nevertheless, the direct association of these new variants in the raise of lethality rate observed during the last outbreak has to be demonstrated. PMID:22405440

Inequities in access to health care in different health systems: a study in municipalities of central Colombia and north-eastern Brazil

PubMed Central

2014-01-01

Introduction Health system reforms are undertaken with the aim of improving equity of access to health care. Their impact is generally analyzed based on health care utilization, without distinguishing between levels of care. This study aims to analyze inequities in access to the continuum of care in municipalities of Brazil and Colombia. Methods A cross-sectional study was conducted based on a survey of a multistage probability sample of people who had had at least one health problem in the prior three months (2,163 in Colombia and 2,167 in Brazil). The outcome variables were dichotomous variables on the utilization of curative and preventive services. The main independent variables were income, being the holder of a private health plan and, in Colombia, type of insurance scheme of the General System of Social Security in Health (SGSSS). For each country, the prevalence of the outcome variables was calculated overall and stratified by levels of per capita income, SGSSS insurance schemes and private health plan. Prevalence ratios were computed by means of Poisson regression models with robust variance, controlling for health care need. Results There are inequities in favor of individuals of a higher socioeconomic status: in Colombia, in the three different care levels (primary, outpatient secondary and emergency care) and preventive activities; and in Brazil, in the use of outpatient secondary care services and preventive activities, whilst lower-income individuals make greater use of the primary care services. In both countries, inequity in the use of outpatient secondary care is more pronounced than in the other care levels. Income in both countries, insurance scheme enrollment in Colombia and holding a private health plan in Brazil all contribute to the presence of inequities in utilization. Conclusions Twenty years after the introduction of reforms implemented to improve equity in access to health care, inequities, defined in terms of unequal use for equal need

This essay presents an analysis of the evolution of environmental health management in Colombia, covering the period from the introduction of the Colombian Healthcare Code (1979) to laws 99 and 100 in 1993 and the introduction of Environmental Health Policy in Bogotá DC (2011). It proposes a conceptual model for environmental health management at three levels: proximal (physical, chemical and biological setting), intermediate (natural and cultural environment) and distal (economic, political and social structures). Relevant aspects of environmental health policy in Bogotá are analysed based on the proposed model.

The incrimination of sand flies belonging to verrucarum species group in the leishmaniasis transmission underscores the need for a detailed information on the geographical distribution of these species. The current listing adds 34 new records that extend significantly the knowledge of the geographical distribution of the verrucarum group in Colombia. The most important new records pertain to Lutzomyia spinicrassa in the tropical dry forest of the Atlantic coast, Lutzomyia ovallesi in the Orinoco and Amazon River watersheds regions of Colombia, and the sympatric occurrence of Lutzomyia spinicrassa and Lutzomyia quasitownsendi in the eastern chain of the Andes mountains. Additionally, the municipal and altitudinal distributions are compiled for 19 new species recorded for Colombia. The series townsendi of the verrucarum group generally restricted to premontane and lower montane zones based on distribution data on Lutzomyia longiflocosa, L. quasitownsendi, Lutzomyia sauroida, L. spinicrassa, Lutzomyia torvida, Lutzomyia townsendi and Lutzomyia youngi. The series verrucarum is distributed from the tropical lowland to the montane zones, and includes species with wide geographical range (Lutzomyia evansi, Lutzomyia columbiana, L. ovallesi, Lutzomyia nuneztovari, Lutzomyia nevesi), and species of highly endemic distribution (Lutzomyia andina, Lutzomyia disiuncta, Lutzomyia moralesi, Lutzomyia antioquiensis). Members of the series pia (Lutzomyia pia, Lutzomyia limafalcaoae) and the series serrana (Lutzomyia serrana) occur from the tropical lowlands to the lower montane zones. The altitudinal divergences may be intrinsically tied to speciation process, especially as it relates to the climatic and geologic events that have affected the flora and fauna of the Andean region.

Among congenital craniofacial anomalies, orofacial clefts (OFCs) are the most common. Global prevalence is 2 in 1000 and in Colombia, 1 in 700. Our goal was to describe cleft palate (CP) prevalence and cleft lip with or without cleft palate (CL±P) from 2001 to 2015 in Bogota and Cali, Colombia. Using the ECLAMC case-control design method, information was obtained from the Congenital Anomalies Monitoring and Surveillance Programs in Bogota and Cali. We describe the prevalence of cases classified into the following groups: isolated, polymalformed, and syndromic. The proportion of cases and controls was 1:4. Data were analyzed using frequency distribution and Student t test to compare means and 95% confidence intervals (CIs). We identified 529 OFC cases and 2116 controls from 448,930 births: a rate of 11.8 per 10,000 (CI = 10.80-12.83). From the total cases, 73% were identified with CL/CP compared to 27% with CP. Males had higher CL±P (59%) prevalence, whereas the highest neonatal mortality was observed among polymalformed cases (7%). The most common anomaly identified among our cases was cleft lip without isolated cleft palate (58%). We found that OFCs are linked to birthweight, size, and gestational age and higher parity with statistically significant differences in all variables compared to controls. OFC is a highly prevalent anomaly in Colombia, with a range of maternal and infant differences across case subgroups. The identification of important OFC subgroups that follow certain patterns of prevalence may prove useful to primary and tertiary care facilities with the goal of reducing further disability.

We analyzed the frequency of four mitochondrial DNA haplogroups in 424 individuals from 21 Colombian Amerindian tribes. Our results showed a high degree of mtDNA diversity and genetic heterogeneity. Frequencies of mtDNA haplogroups A and C were high in the majority of populations studied. The distribution of these four mtDNA haplogroups from Amerindian populations was different in the northern region of the country compared to those in the south. Haplogroup A was more frequently found among Amerindian tribes in northern Colombia, while haplogroup D was more frequent among tribes in the south. Haplogroups A, C and D have clinal tendencies in Colombia and South America in general. Populations belonging to the Chibcha linguistic family of Colombia and other countries nearby showed a strong genetic differentiation from the other populations tested, thus corroborating previous findings. Genetically, the Ingano, Paez and Guambiano populations are more closely related to other groups of south eastern Colombia, as also inferred from other genetic markers and from archeological data. Strong evidence for a correspondence between geographical and linguistic classification was found, and this is consistent with evidence that gene flow and the exchange of customs and knowledge and language elements between groups is facilitated by close proximity.

ABSTRACT Colombia, South America is currently transitioning to post-conflict status following 6 decades of armed conflict. The population has experienced extensive exposures to potentially traumatic events throughout the lifespan. Sources of trauma exposure include the prolonged armed insurgency, narco-trafficking violence, urban gang violence, violent actions of criminal bands, intra-familial violence, gender-based violence, and sex trafficking. Exposure to potentially traumatic events is related to a variety of psychiatric outcomes, in particular, posttraumatic stress disorder. Given this context of lifetime trauma exposure, socio-demographic patterns of posttraumatic stress disorder were explored in a sample of residents of Medellin, Colombia, the nation's second largest city and a nexus for multiple types of trauma exposure.

To assess the long-term clinical and economic impact of integrated pump/CGM technology therapy as compared to multiple daily injections (MDI), for the treatment of type 1 diabetes (T1D) in Colombia. The CORE Diabetes Model was used to simulate a hypothetical cohort of patients with T1D. Mean baseline characteristics were taken from a clinical study conducted in Colombia and a healthcare payer perspective was adopted, with a 5% annual discount rate applied to both costs and outcomes. The integrated pump/CGM improved mean life expectancy by 3.51 years compared with MDI. A similar increase occurred in mean quality-adjusted life expectancy with an additional 3.81 quality-adjusted life years (QALYs). Onset of diabetes-related complications was also delayed as compared to MDI, and mean survival time free of complication increased by 1.74 years with integrated pump/CGM. Although this increased treatment costs of diabetes as compared to MDI, savings were achieved thanks to reduced expenditure on diabetes-related complications. The estimated incremental cost-effectiveness ratio (ICER) for SAP was Colombian Pesos (COP) 44,893,950 (approximately USD$23,200) per QALY gained. Improved blood glucose control associated to integrated pump/CGM results in a decreased incidence of diabetes-related complications and improves life expectancy as compared to MDI. Using recommended thresholds from the World Health Organization and previous coverage decisions about health technologies in Colombia, it is a cost-effective alternative to MDI for the treatment of type 1 diabetes in Colombia.

Candida auris is a multidrug-resistant yeast associated with hospital outbreaks worldwide. During 2015-2016, multiple outbreaks were reported in Colombia. We aimed to understand the extent of contamination in healthcare settings and to characterize the molecular epidemiology of C. auris in Colombia. We sampled patients, patient contacts, healthcare workers, and the environment in four hospitals with recent C. auris outbreaks. Using standardized protocols, people were swabbed at different body sites. Patient and procedure rooms were sectioned into four zones and surfaces were swabbed. We performed whole-genome sequencing (WGS) and antifungal susceptibility testing (AFST) on all isolates. Seven (41%) of the 17 people swabbed were found to be colonized. C. auris was isolated from 37/322 (12%) environmental samples. These were collected from a variety of items in all four zones. WGS and AFST revealed that although isolates were similar throughout the country, isolates from the northern region were genetically distinct and more resistant to amphotericin B (AmB) than the isolates from central Colombia. Four novel non-synonymous mutations were found to be significantly associated with AmB resistance. Our results show that extensive C. auris contamination can occur and highlight the importance of adherence to appropriate infection control practices and disinfection strategies. Observed genetic diversity supports healthcare transmission and a recent expansion of C. auris within Colombia with divergent AmB susceptibility.

Colombia: A source of hydrocarbons for the world

Colombia progressively has become attractive to those exploring for oil. The policy established by the government in 1974 has attracted large-, medium-, and small-sized companies to come to the country in search for petroleum and gas reserves in the 780,000 km[sup 2] which encompass its 13 sedimentary basins. The dynamics with which association contracts can be signed with the state company Ecopetrol, has been a decisive factor in the success of its oil policy, a success reflected in the existence of over 90 contracts in force and the involvement of more than 40 foreign oil companies in operations in Colombia.more » Historically, exploration was carried out to search for hydrocarbons in known zones and in pursuit of traditional structures, which brought both, great discoveries and resounding failures. State of the art in exploration has permitted a better understanding of the geological phenomena which have led to the accumulation of hydrocarbons. Ecopetrol has begun to explore with the new [open quotes]play concepts[close quotes] taking into account aspects never before considered, weighing risk factors against the possibility of discovering important quantities of hydrocarbons in [open quotes]frontier regions.[close quotes] These new ideas allow the construction of geological models before deciding to drill. This [open quotes]new focus[close quotes] is based on global geological analogies.

To date, no research has been published on the health related quality of life (HRQOL) and mental health of children with spinal cord injury and disorders (SCI/D) in Latin America, although limited previous research in Western countries has demonstrated the debilitating and chronic nature of these conditions in children. The aim was to examine the connections between HRQOL and mental health in children with SCI/D from Neiva, Colombia. Thirty children (8- 17 years) were recruited from the Hospital Universatario Hernando Mocaleano Perdomo in Neiva, Colombia. Participants completed self-report measures administered verbally by trained research staff. A correlation matrix generally suggested that higher HRQOL was robustly associated with better mental health. A series of multiple regressions found that HRQOL explained 50.5% of the variance in children's depression, 31.5% of the variance in worry, and 41.9% of the variance in social anxiety. Within these regressions, emotional and social functioning were uniquely associated with depression, and emotional functioning was uniquely associated with social anxiety. This is the first published study to examine psychosocial outcomes in children with SCI/D in Latin America, and its findings suggest that future research and interventions for children with SCI/D in Colombia - and possibly in other regions of Latin America - would benefit from emphasizing emotional and social functioning.

Gender equity and health sector reform in Colombia: mixed state-market model yields mixed results.

PubMed

Ewig, Christina; Bello, Amparo Hernández

2009-03-01

In 1993, Colombia carried out a sweeping health reform that sought to dramatically increase health insurance coverage and reduce state involvement in health provision by creating a unitary state-supervised health system in which private entities are the main insurers and health service providers. Using a quantitative comparison of household survey data and an analysis of the content of the reforms, we evaluate the effects of Colombia's health reforms on gender equity. We find that several aspects of these reforms hold promise for greater gender equity, such as the resulting increase in women's health insurance coverage. However, the reforms have not achieved gender equity due to the persistence of fees which discriminate against women and the introduction of a two-tier health system in which women heads of household and the poor are concentrated in a lower quality health system.

[Users' and community leaders' perceptions of their capacity to influence the quality of health care: case studies of Colombia and Brazil].

PubMed

Delgado-Gallego, María Eugenia; Vázquez, María Luisa

2009-01-01

Health system reforms in Colombia and Brazil introduced policies that promote social participation in health care quality control. The objective of this paper was to analyze users' and leaders' perceptions of their capacity to achieve changes in the countries' health services. An exploratory and descriptive qualitative study was performed with individual interviews and focus groups of users and leaders in Colombia and Brazil. Most informants perceived themselves as having the capacity to induce changes to improve the quality of health services. They attributed this capacity primarily to internal factors related to their participatory behavior, plus only one external factor, the availability of institutional participatory spaces. The lack of capacity to influence change was only related to passive attitudes and fear of retaliation in Colombia. The existence of a population with high self-perceived capacity to achieve change appears as a potential factor to be strengthened, while institutional democratic space needs to improve in order to enhance the effectiveness of social participation in health policies.

Cutaneous leishmaniasis causes a high disease burden in Colombia, and available treatments present systemic toxicity, low patient compliance, contraindications, and high costs. The purpose of this study was to estimate the cost-effectiveness of thermotherapy versus Glucantime in patients with cutaneous leishmaniasis in Colombia. Cost-effectiveness study from an institutional perspective in 8133 incident cases. Data on therapeutic efficacy and safety were included, calculating standard costs; the outcomes were disability adjusted life years (DALYs) and the number of patients cured. The information sources were the Colombian Public Health Surveillance System, disease burden studies, and one meta-analysis of controlled clinical trials. Incremental cost-effectiveness was determined, and uncertainty was evaluated with tornado diagrams and Monte Carlo simulations. Thermotherapy would generate costs of US$ 501,621; the handling of adverse effects, US$ 29,224; and therapeutic failures, US$ 300,053. For Glucantime, these costs would be US$ 2,731,276, US$ 58,254, and US$ 406,298, respectively. With thermotherapy, the cost would be US$ 2062 per DALY averted and US$ 69 per patient cured; with Glucantime, the cost would be US$ 4241 per DALY averted and US$ 85 per patient cured. In Monte Carlo simulations, thermotherapy was the dominant strategy for DALYs averted in 67.9% of cases and highly cost-effective for patients cured in 72%. In Colombia, thermotherapy can be included as a cost-effective strategy for the management of cutaneous leishmaniasis. Its incorporation into clinical practice guidelines could represent savings of approximately US$ 10,488 per DALY averted and costs of US$ 116 per additional patient cured, compared to the use of Glucantime. These findings show the relevance of the incorporation of this treatment in our country and others with similar parasitological, clinical, and epidemiological patterns.

Casalla, Robin; Scheffrahn, Rudolf; Korb, Judith

2016-01-01

Abstract A new species of drywood termite (Kalotermitidae), Cryptotermes colombianus, is described and new records for Cryptotermes cylindroceps and Cryptotermes mangoldi are presented from the Caribbean coast of Colombia. Cryptotermes colombianus is described from two soldiers and genetic sequences. This unusual species differs noticeably from other regional Cryptotermes species for its weak and inconspicuous definition of the frontal and genal horns and its acute angle of the frons with respect to the vertex. Cryptotermes colombianus clustered with species from the Ethiopian and Oriental region and it is closely related to Cryptotermes havilandi. Cryptotermes cylindroceps is widely distributed along the Colombian Caribbean coast, commonly associated with dead wood in mangrove habitats. It also is commonly found in wooden furniture, constituting an important household pest. Cryptotermes mangoldi is reported from the Caribbean mainland for the first time. With these new records, there are now five Cryptotermes species for Colombia, including the pest species Cryptotermes brevis and Cryptotermes dudleyi. This new description raises the numbers of Neotropical Cryptotermes to a total of 34 species, of which 2 are fossils, 4 introduced, and 28 endemic. PMID:27408575

Describe the socio-demographic characteristics of anophthalmic patients examined at specialized centers of four cities in Colombia to know the different causes of eyeball loss. A transversal retrospective study was done of 511 medical records from the specialized practices of four cities in Colombia. Socio-demographic data of patients who were seen between January 2011 and December 2013 were compiled. SOFA Statistics software v1.4.6 was used for this analysis. An analysis throughout the measures of central tendency for numerical variables was developed, and the descriptive statistics were used for the categorical variables. Almost 63% of the data belonged to male patients. Eyeball loss was more frequent in patients over 40 years of age. Fifty-one percent of the patients suffered eyeball loss due to traumatic causes, 40.2% due to pathological causes, and 4.6% due to congenital anomalies. The most frequent specific causes were glaucoma (19%), ocular cancer (15.4%), and home accidents (11,2%). Around 60% of the anophthalmic patients belonged to low socioeconomic level. It is important to highlight that more than half of the analyzed anophthalmia cases originated in some type of trauma; this means that they could be considered potentially avoidable losses. Complications deriving from glaucoma became the most frequent cause of anophthalmia in the pathological origin group, which suggests a reflection regarding the strategies of early detection of the disease and access to proper treatment. It is also showed the need to develop an efficient system to manage information.

Introducción. La detección temprana del riesgo de problemas emocionales y del comportamiento en niños puede contribuir al desarrollo de estrategias que promuevan la salud mental desde la primera infancia. En Colombia no existe una herramienta validada para dicha detección.Objetivos. Seleccionar, adaptar y establecer la validez de criterio de una escala de tamización de problemas emocionales y del comportamiento en niños menores de seis años.Materiales y métodos. A partir de una revisión de la literatura y un consenso de expertos, se seleccionó la herramienta Early Childhood Screening Assessment (ECSA). Posteriormente, se llevó a cabo su adaptación lingüística y se determinó la validez de criterio mediante una curva de características de recibidor-operador (Receiver Operating Characteristic, ROC), y se la comparó con el cuestionario Child Behavior Checklist (CBCL 1,5-5). En el estudio participaron 206 cuidadores de niños entre el año y medio y los seis años de edad de la ciudad de Tunja y el municipio de Sopó.Resultados. La puntuación del ECSA presentó una buena correlación con la puntuación t total del CBCL 1,5-5 (ro de Spearman=0,75; p<0,01). La escala ECSA tuvo una sensibilidad de 86 % y una especificidad de 82 % al establecer un punto de corte de 24 para la población estudiada.Conclusión. En este primer estudio de adaptación y validación de la versión en español de la escala ECSA, se detectaron buenos valores de sensibilidad y especificidad para la tamización de problemas emocionales y del comportamiento en la primera infancia.

Sand flies include a group of insects that are of medical importance and that vary in geographic distribution, ecology, and pathogen transmission. Approximately 163 species of sand flies have been reported in Colombia. Surveillance of the presence of sand fly species and the actualization of species distribution are important for predicting risks for and monitoring the expansion of diseases which sand flies can transmit. Currently, the identification of phlebotomine sand flies is based on morphological characters. However, morphological identification requires considerable skills and taxonomic expertise. In addition, significant morphological similarity between some species, especially among females, may cause difficulties during the identification process. DNA-based approaches have become increasingly useful and promising tools for estimating sand fly diversity and for ensuring the rapid and accurate identification of species. A partial sequence of the mitochondrial cytochrome oxidase gene subunit I (COI) is currently being used to differentiate species in different animal taxa, including insects, and it is referred as a barcoding sequence. The present study explored the utility of the DNA barcode approach for the identification of phlebotomine sand flies in Colombia. We sequenced 700 bp of the COI gene from 36 species collected from different geographic localities. The COI barcode sequence divergence within a single species was <2% in most cases, whereas this divergence ranged from 9% to 26.6% among different species. These results indicated that the barcoding gene correctly discriminated among the previously morphologically identified species with an efficacy of nearly 100%. Analyses of the generated sequences indicated that the observed species groupings were consistent with the morphological identifications. In conclusion, the barcoding gene was useful for species discrimination in sand flies from Colombia.

The hydro-climatology of Colombia exhibits strong natural variability at a broad range of time scales including: inter-decadal, decadal, inter-annual, annual, intra-annual, intra-seasonal, and diurnal. Diverse applied sectors rely on quantitative predictions of river discharges for operational purposes including hydropower generation, agriculture, human health, fluvial navigation, territorial planning and management, risk preparedness and mitigation, among others. Various methodologies have been used to predict monthly mean river discharges that are based on "Predictive Analytics", an area of statistical analysis that studies the extraction of information from historical data to infer future trends and patterns. Our study couples the Empirical Mode Decomposition (EMD) with traditional methods, e.g. Autoregressive Model of Order 1 (AR1) and Neural Networks (NN), to predict mean monthly river discharges in Colombia, South America. The EMD allows us to decompose the historical time series of river discharges into a finite number of intrinsic mode functions (IMF) that capture the different oscillatory modes of different frequencies associated with the inherent time scales coexisting simultaneously in the signal (Huang et al. 1998, Huang and Wu 2008, Rao and Hsu, 2008). Our predictive method states that it is easier and simpler to predict each IMF at a time and then add them up together to obtain the predicted river discharge for a certain month, than predicting the full signal. This method is applied to 10 series of monthly mean river discharges in Colombia, using calibration periods of more than 25 years, and validation periods of about 12 years. Predictions are performed for time horizons spanning from 1 to 12 months. Our results show that predictions obtained through the traditional methods improve when the EMD is used as a previous step, since errors decrease by up to 13% when the AR1 model is used, and by up to 18% when using Neural Networks is combined with the

An active search for Mycobacterium leprae drug resistance was carried out, 243 multibacillary patients from endemic regions of Colombia were included from 2004 to 2013 in a surveillance program. This program was a World Health Organization initiative for drug resistance surveillance in leprosy, where Colombia is a sentinel country. M. leprae DNA from slit skin smear and/or skin biopsy samples was amplified and sequenced to identify mutations in the drug resistance determining region (DRDR) in rpoB, folP1, gyrA, and gyrB, the genes responsible for rifampicin, dapsone and ofloxacin drug-resistance, respectively. Three isolates exhibited mutations in the DRDR rpoB gene (Asp441Tyr, Ser456Leu, Ser458Met), two in the DRDR folP1 gene (Thr53Ala, Pro55Leu), and one isolate exhibited mutations in both DRDR rpoB (Ser456Met) and DRDR folP1 (Pro55Leu), suggesting multidrug resistance. One isolate had a double mutation in folP1 (Thr53Ala and Thr88Pro). Also, we detected mutations outside of DRDR that required in vivo evaluation of their association or not with drug resistance: rpoB Arg505Trp, folP1 Asp91His, Arg94Trp, and Thr88Pro, and gyrA Ala107Leu. Seventy percent of M. leprae mutations were related to drug resistance and were isolated from relapsed patients; the likelihood of relapse was significantly associated with the presence of confirmed resistance mutations (OR range 20.1–88.7, p < 0.05). Five of these relapsed patients received dapsone monotherapy as a primary treatment. In summary, the current study calls attention to M. leprae resistance in Colombia, especially the significant association between confirmed resistance mutations and relapse in leprosy patients. A high frequency of DRDR mutations for rifampicin was seen in a region where dapsone monotherapy was used extensively. PMID:27706165
