The research has the purpose of analyzing social entrepreneurship in an intercultural key from the perspective and experience of the indigenous people, specifically the Arhuaco community, located in Colombia. It seeks to characterize business management as a collective confluence capable of subverting unfair relationships by equitable provisions; whenever actions are promoted in favor of managing well-being. The skills are based on the contributions of intercultural dialogue as coexistence mediated through words, tolerance, respect, ethical co-responsibility, by validating the cultural contributions that otherness presents. In this context, education is available as an opportunity by enabling the resources and skills of the best confluences. It is a study from the interpretive paradigm, articulated from an experiential introspective epistemic approach supported by the ethnographic method as a qualitative inquiry. [ABSTRACT FROM AUTHOR]

Colombia endured 70 years of internal conflict, but despite a peace agreement, violence continues to be significant in the post-conflict era. Violence degrades the health and well-being of affected populations and it engenders psychological distress. Little is known about the impact of violence on the mental health of sexual and gender minority populations in Colombia. This study aimed to examine the frequency and sources of violence among cisgender men who have sex with men (MSM) and transgender women and their association with depressive symptoms and substance use. We administered a survey to 942 MSM and 58 transgender women recruited using respondent-driven sampling. We estimated the relationship between mental health indicators and experiences of violence using stepwise logistic and linear regressions, controlling for income, education, age, race, and mistreatment for being effeminate when younger. Respondent-driven sampling adjusted prevalence of any type of violence was 60.9% for the total sample, 59.8% for MSM, and 75.1% for transgender women. Experiences of violence were significantly related to depressive symptoms, binge drinking and drug use for the MSM sample. Violence perpetrated by family members or acquaintances was associated with greater depressive symptoms, and violence perpetrated by partners and strangers was associated with increased binge drinking and drug use. These results provide significant evidence of the negative association of experiences of violence and the mental health of sexual and gender minority people, a vulnerable population in Colombia. This study addresses issues of diversity regarding sexual orientation and gender identity in a Latin American middle-income country. [ABSTRACT FROM AUTHOR]

Stevia cultivation is a viable agricultural activity in Colombia and the Caribbean region, which is based on the Morita II clone, representing a high risk of biotic and abiotic factors. For this reason, the morphoagronomic characterization of 25 clones from the germplasm collection at the University of Córdoba is important in order to group them according to their genetic affinity, and to identify and select those with the best agronomic advantages. For this purpose, 19 morphoagronomic descriptors were applied (11 quantitative and 8 qualitative); a dendrogram was performed using Ward's method to distinguish among groups and a multivariate analysis of principal components to identify the descriptors that contributed to variability. Two main components were identified, the first, contributing with 47,74% and the second with 21,67% of the total variation, supported by performance-related characters. Likewise, the identification of 6 late flowering clones, dry leaf production and erect growth habit, which is of interest to advance in genetic breeding programs in the species.

Given the high popularity that collective investment funds (cifs) have been gaining and their growing participation in the financial market, both in terms of the amount of investments and the number of investors, it is necessary to have tools that allow for adequate and timely identification of risks, in order to prevent an effect on the stability of the financial system. However, there is a lack of literature on early warnings for these funds, since most of the papers are focused on the banking sector. This document aims to develop an early warning indicator that allows the identification of cif vulnerabilities, with enough time of anticipation for policymakers to implement measures for their containment. In order to achieve this objective, a widely known early warning measure in the banking sector, such as the European Central Bank's Domestic Systemic Risk Indicator (d-SRI), will be adapted to the cif scenario in Colombia. The results obtained show that in the event of a shock of one standard deviation in the cif early warning indicator (iate fic), a drop of 1.4 percentage points in the quarterly growth of the fund's net value (fnv) is expected in the six months following the occurrence of the shock. The findings showed in this work represent an important advance in the detection of vulnerabilities of investment funds and can be of great help to policymakers in making decisions under scenarios of uncertainty in the future behavior of the cif industry.

Background: Medical residents' training in ultrasonography usually follows the recommendations of the American College of Emergency Physicians (ACEP), even though these do not provide specific technical guidelines. Adequate training is considered to require 25 practical iterations in the majority of ultrasound procedures. However, the effectiveness of this approach has not been verified experimentally. We set out to determine the number of repetitions required for an acceptable ultrasound procedure of the inferior vena cava (IVC), as an important and emerging ultrasound procedure in cardiology. Methods: Using three human models, each of eight medical residents in the Emergency Medicine (EM) Program at the Universidad del Rosario performed 25 iterations of the recommended procedure, with image quality evaluation by an EM physician expert in the technique. Logistic regression analysis was used to determine the lowest number of repetitions required to achieve an adjusted probability of success of 80 and 90 %, respectively. Results: We obtained 200 ultrasound images. The percentage success by each resident ranged from 52 to 96 %. There was no statistical significance in the relation between gender and success ( p = 0.83), but there was an association between year of residency and success ( p < 0.001). The average time taken for each procedure was 17.3 s (SD 8.1); there was no association between the time taken and either repetition number or image quality. We demonstrate that eleven repetitions are required to achieve acceptable image quality in 80 %, and that 21 repetitions are required to achieve acceptable image quality in 90 %. Conclusions: This is the first study to formally evaluate the effectiveness of recommended training in ultrasound techniques. Our findings demonstrate that training comprising 25 procedural repetitions is easily sufficient to achieve optimal image quality, and they also provide empiric knowledge toward elucidating the times and minimum repetitions needed to acquire and improve ultrasonographic technique in novice operators to a level which fulfills quality requirements for interpretation.

Objectives. We estimated HIV prevalence among men who have sex with men (MSM) and transgender women in Bogotá, Colombia, and explored differences between HIV-positive individuals who are aware and unaware of their serostatus. Methods. In this cross-sectional 2011 study, we used respondent-driven sampling (RDS) to recruit 1000 MSM and transgender women, who completed a computerized questionnaire and received an HIV test. Results. The RDS-adjusted prevalence was 12.1% (95% confidence interval [CI] = 8.7, 15.8), comparable to a previous RDS-derived estimate. Among HIV- positive participants, 39.7% (95% CI = 25.0, 54.8) were aware of their serostatus and 60.3% (95% CI = 45.2, 75.5) were unaware before this study. HIV-positive--unaware individuals were more likely to report inadequate insurance coverage, exchange sex (i.e., sexual intercourse in exchange for money, goods, or services), and substance use than other participants. HIV-positive--aware participants were least likely to have had condomless anal intercourse in the previous 3 months. Regardless of awareness, HIV-positive participants reported more violence and forced relocation experiences than HIV-negative participants. Conclusions. There is an urgent need to increase HIV detection among MSM and transgender women in Bogotá . HIV-positive--unaware group characteristics suggest an important role for structural, social, and individual interventions. [ABSTRACT FROM AUTHOR]

Background: Medicinal plant species contribute significantly to folk medicine in Colombia. However, few local studies have investigated whether species used are introduced or native and whether there is a difference in importance of native and introduced medicinal plant species. The aim of the present study was to describe the use of medicinal plants within two municipalities, Campo Hermoso and Zetaquira, both in the department of Boyacá, Colombia and to assess the importance of native and introduced plants to healers, amateur healers and local people. As local healers including amateur healers have no history of introduced species our working hypotheses (H1-2) were that H1: native and introduced medicinal plant species are of equal importance and H2: healers and amateur healers do not differentiate in their preferences between native and introduced medicinal plant species. Methods: Ten villages were included in the study. A combination of quantitative and qualitative methods was used including questionnaires, semi-structured interviews, in- depth interviews, and open talks. Voucher specimens were collected in home gardens and during field walks. For data analysis, we calculated use value indices and Jaccard index and tested for the above hypothesis using Spearman rank-correlation coefficients and Wilcoxon-Mann-Whitney tests. Results: Eighty medicinal plant species were described by locals as the most frequently used. Of these, 78 species were taxonomically identified, distributed within 41 families and 74 genera, which included 35 native species and 43 introduced. The highest valued families were: Asteraceae, Lamiaceae, Apiaceae, Rutaceae and Verbenaceae. The species ranked highest according to their Use Values, in both municipalities, were Mentha suaveolens Ehrh., Ambrosia cumanensis Kunth, and Verbena littoralis Kunth. Introduced species were more important than native ones in Zetaquira, while there was no difference in importance in Campo Hermoso. While healers relied most on the uses of native species, amateur healers were inclined to rely on introduced species. Medicinal plant administration in both municipalities follow the usual pattern: Leaves are used most commonly prepared by decoction or infusion and administrated orally. Conclusions: The high proportion of introduced plant species used in the local traditional medicines is similar to the results of a number of other ethnobotanical studies and emphasise the need for efforts to record and maintain traditional knowledge on native species.

This article addresses an emerging issue in health care systems: the impact of judicial rulings on public policy regarding financing and delivery of health care services, and the attendant tensions, contradictions and questions. In Colombia, HIV/AIDS patients' use of a legal instrument called tutela, or writ of protection, has produced abundant jurisprudence and prompted health authorities to respond with decisions about HIV/AIDS service coverage that do not consider epidemiologic criteria and sustainability, introducing distortions in the health care system with respect to financing, priority-setting and universality.

In Colombia, the exploration, exploitation, transport, and processing of hydrocarbons since the beginning of the 20th century have caused great territory transformations and ecosystem degradation. These processes have impacted adversely the indigenous communities security, exposing their culture and, in some cases, their existence itself. Even though, facing oil and, in general, mineral exploitation, the rights of this population have changed historically and their autonomy and integrity is protected by the 1991 Constitution, the communities are still highly vulnerable to the intervention on the ecosystem they inhabit. The environmental degradation directly arisen from the oil exploitation activities and the colonization they have driven, has become a threat to the security of the communities whose territories and subsistence resources have been reduced. Colonization and the resulting natural resource pressure are mainly caused by the poverty of the country population that seek new lands to occupy and these two facts cause in turn the environmental degradation that impoverish the ethnic communities by affecting their living sources, thereby causing insecurity to the indigenous population. In addition, environmental degradation and territory reduction risk these human groups' culture by impacting their values, tradition, authorities and, in general, their way of living, and therefore turn into a threat to their security.

Hematology and blood chemistry tests constitute an easy-to-apply veterinary tool that evaluates an organism's systemic functioning and disease process by comparing the level of specific analytes against species norms. Such analyses help monitor marine mammals' health and nutritional status. Although reference values have been published for a few manatee populations, there are none for Antillean manatees (Trichechus manatus manatus) in Colombia. We aim to establish the reference values for hematology and serum chemistries for these manatees and determine if there are variations between individuals of different age groups and sex. Thus, we obtained whole blood and serum samples from 45 rehabilitated manatees from Colombia between 1992 and 2021. Complete Blood Count and Comprehensive Metabolic Panel values were calculated, and differences between age groups and sex were determined. Results were compared with published reference intervals of other Antillean manatee populations, Florida manatees (Trichechus manatus latirostris), and Amazonian manatees (Trichechus inunguis) from Brazil. We determined the reference intervals of hematology and serum chemistry for manatees in Colombia for different age and sex categories. No relevant clinical variations were found in hematological parameters due to sex. Marked differences were found between age groups, mainly among young animals with an expected faster metabolism. There were significant variations between hematological and blood chemistry values when the Colombian manatees were compared to manatees from Puerto Rico and Amazonian manatees from Brazil. Such variations are likely influenced by evolutionary history and environmental factors associated with differences in habitat salinity and diet. We recommend that future studies correlate these blood tests with specific panels. We further recommend conducting wild manatee health assessments as this information will yield essential data for species management schemes needed due to the multiple anthropogenic and environmental threats that manatees face today which put the Colombian manatee's health and ultimate survival at risk.

This work presents the floristic inventory of six areas of Tropical dry forest in Department of Atlántico and Bolívar. The localities studied are priority areas for biodiversity conservation, maintenance of environmental services, and protection of archaeological values, landscape and / or tourism. There were a total of 314 species distributed in 232 genera and 73 families. Leguminosae is the family most represented in this study, with 61 species and 37 genera, followed Malvaceae (17/14) and Bignoniaceae (16/14). The habit better represented in species richness was trees (44%), followed by shrubs (21%) and herbs (16%). Between all plant species recorded, 20 have been evaluated under IUCN's criterions, four of them, are included in the "endangered" category (EN): Aspidosperma polyneuron (carreto), Belencita nemorosa (calabacilla), Bulnesia arborea (guayacán) and Pachira quinata (ceiba roja). It is important to point out that 45 % of the plants have at least one known use in the region, which are linked with social, cultural and ecological process. [ABSTRACT FROM AUTHOR]

This study aimed to identify Top, Bottom, and Versatile sexual role identities and anal sex behavior profiles using latent class analysis in a sample of 942 sexual minority men living in Bogotá. A Versatile-insertive and receptive class (52.2%) was the most prevalent of the four resulting classes, whereas the least common was a class (1.7%) that did not use labels and had a low probability of anal sex. We examined whether identity and relational factors (i.e., sexual orientation, LGBT collective identity, and partner type) were associated with profiles. Gay identity was associated with versatile and receptive classes and bisexual identity was associated with insertive and versatile classes. LGBT collective identity was associated with the class characterized by Bottom identity and receptive positioning. Partner type was not associated with class membership, but versatile behaviors were more common among encounters with a main partner. Models using data at different timescales offered consistent patterns of behavior between the last encounter and the past three months, though the versatile class in the three-month model split into two classes based on frequency of versatile positioning. Findings highlight the relationship between sexual identity and positioning and can inform interventions for sexual health education and identity development.

Purpose: We assessed the association between sexual orientation and gender identity change efforts (SOGICE) experiences and lifetime suicide morbidity among sexual and gender minority (SGM) groups in Colombia. Methods: A sample of 4160 SGM Colombian adults responded to an online cross-sectional survey. We used binary logistic regression to assess the relationship between SOGICE and suicide morbidity for the overall sample and stratified by SGM group. Results: We found a high prevalence of suicidal ideation (56%), suicide planning (54%), suicide attempt (25%), and SOGICE experiences (22%). There were significant differences in the prevalence of suicide morbidity and SOGICE experiences across SGM groups, with transgender men and gender nonbinary participants being generally most at risk. SOGICE experiences were associated with 69% increased odds of suicidal ideation, 55% increased odds of suicide planning, and 76% increased odds of suicide attempt. Stratified analyses by SGM group showed that the association of SOGICE experiences with suicide morbidity varied by SGM group, and it was particularly detrimental for cisgender sexual minority men. Conclusions: Suicide morbidity among SGM adults in Colombia is high, with rates that are 8-22 times higher than in the general population. SOGICE experiences further exacerbate suicide risk. The study findings highlight the need to design and implement policies affirming diverse sexual orientation and gender identities in Colombia and to ban SOGICE practices. These findings also highlight the importance of recognizing the variability within SGM groups and the need to examine these groups separately rather than treating them as a monolithic group.

Using a community-based participatory approach, we developed a film to promote HIV testing among young men who have sex with men (MSM) in Bogotá. Using a 5-step process to develop the intervention, we conducted 11 focus groups with MSM (n = 141) to receive community feedback at each step. To evaluate the intervention we recruited 300 young MSM to complete a baseline survey in December 2017. Between February-June 2018, 63 participants watched the film and completed a post-viewing survey, which showed the intervention was acceptable for the target population. Between August-December 2018, 48 MSM who watched the film and 47 who did not (control group) completed a follow-up survey. To obtain preliminary evidence of the efficacy of the intervention, we assessed the main effect of time (baseline vs. follow-up) and the interaction between time and group (intervention vs. control) on HIV testing uptake and intentions, and knowledge of HIV transmission dynamics and HIV-related rights. Knowledge of HIV rights increased from baseline to follow-up in the intervention group only. HIV Knowledge increased for both groups. HIV testing intentions increased significantly more for non-gay-identified men in the intervention group, but the overall effect of the intervention was not significant. Testing uptake did not change.

Objective: To establish the clinical, pathological and microbiological association of Helicobacter pylori in gastric biopsies in a population of the department of Caldas (Colombia)., Materials and Methods: We included 72 patients, who were referred for digestive endoscopy to the San Marcel clinic in the city of Manizales during the second half of 2015; two biopsies of the antrum and two of the body of the stomach were taken for histopathological study and microbiological culture. Data were submitted to descriptive and relational statistical procedures., Results: H. pylori was found in 47.2% by histological analysis and 26.4% by microbiological culture, with predominance in the female sex. Epigastralgia is the main reason for consultation associated with H. pylori infection., Conclusion: we found an association between the reason for consultation, female sex, microbiological culture and histological presence of H. pylori. Age was associated with established endoscopic diagnosis. The culture presented a high specificity (84.2%) and a low sensitivity (38.2%), compared to the histopathological finding.

This study used mixed methods to examine characteristics related to HIV testing among men who have sex with men (MSM) in Bogotá, Colombia. A sample of 890 MSM responded to a computerized quantitative survey. Follow-up qualitative data included 20 in-depth interviews with MSM and 12 key informant interviews. Hierarchical logistic set regression indicated that sequential sets of variables reflecting demographic characteristics, insurance coverage, risk appraisal, and social context each added to the explanation of HIV testing. Follow-up logistic regression showed that individuals who were older, had higher income, paid for their own insurance, had had a sexually transmitted infection, knew more people living with HIV, and had greater social support were more likely to have been tested for HIV at least once. Qualitative findings provided details of personal and structural barriers to testing, as well as inter-relationships among these factors. Recommendations to increase HIV testing among Colombian MSM are offered.
