Background: Rickettsiae are obligate intracellular Gram-negative bacteria that are the causative agent of rickettsioses and are spread to vertebrate hosts by arthropods. There are no previous reports of isolation of Rickettsia amblyommatis for Colombia. Methods: A convenience sampling was executed in three departments in Colombia for direct collection of adult ticks on domestic animals or over vegetation. Ticks were screened for the presence of Rickettsia spp. by real-time polymerase chain reaction (qPCR) amplifying the citrate synthase gene (gltA), and the positive sample was processed for isolation and further molecular characterization by conventional PCR. The absolute and relative frequencies were calculated for several tick species variables. All products from conventional PCR were further purified and sequenced by the Sanger technique. Representative sequences of 18 Rickettsia species were downloaded from GenBank. Consensus phylogenetic trees were constructed for the gltA, ompB, ompA, and htrA genes with 1000 replicates, calculating bootstrap values through the maximum likelihood method and the generalized time reversible substitution model in the MEGA 7.0 software program. Results: One female Amblyomma mixtum collected on vegetation was amplified by qPCR (gltA), indicating a frequency of 1.6% (1/61) for Rickettsia spp. infection. Sequence analysis of a rickettsial isolate from this tick in BLASTn showed 100% identity with gltA (340 base pairs [bp]), 99.87% for ompB (782 bp), 98.99% for htrA (497 bp), and 100% for ompA (488 bp) to R. amblyommatis. Concatenated phylogenetic analysis confirmed these findings indicating that the isolate is grouped with other sequences of Amblyomma cajennense complex from Panama and Brazil within the R. amblyommatis clade. Conclusions: This paper describes the isolation and early molecular identification of a R. amblyommatis strain from A. mixtum in Colombia. [ABSTRACT FROM AUTHOR]

Background: Paracoccidioidomycosis is a neglected tropical disease, endemic in several countries of South America including Colombia. We report a case of a patient with Chronic Multifocal Paracoccidioidomycosis with long-standing symptoms and a delayed diagnosis caused by several barriers to achieve it. We did a review of the papers published in Colombia about this disease, focusing in clinical data and eco-epidemiology with the finding of a lack of new information on this topic since the 2000 in our region.Case Presentation: We present a 54-year-old man, farmer in his youth, with a chronic ulcerated lesion in the lower lip similar to a lip carcinoma, a deforming lesion in the nose, and respiratory symptoms with emphysematous lung. Lip biopsy with silver methenamine stain revealed small and large budding yeasts that resembles a "mariner's wheel" confirming Chronic Multifocal Paracoccidioidomycosis. He was treated successfully but subsequently lost to follow up.Conclusions: It is very important to focus attention, reinforce the search and create networks for the study of neglected tropical diseases. The presented case illustrates a usual clinical presentation, but with a delayed diagnosis due to the difficulties that still occur in some regions like ours for the early recognition of a case of chronic multifocal paracoccidioidomycosis.

Background: Despite suicide's public health significance and global mental health awareness, current suicide prevention efforts show limited impact, posing a challenge for low- and middle-income countries. This study aimed to develop a dynamic simulation model that could be used to examine the potential effectiveness of alternative interventions for reducing youth mental health problems and suicidal behavior in Bogotá, Colombia. Methods: A system dynamics model was designed using a participatory approach involving three workshops conducted in 2021 and 2022. These workshops engaged 78 stakeholders from various health and social sectors to map key mental health outcomes and influential factors affecting them. A model was subsequently developed, tested, and presented to the participants for interactive feedback, guided by a moderator. Simulation analyses were conducted to compare projected mental health outcomes for a range of intervention scenarios with projections for a reference scenario corresponding to business-as-usual. Results: A total of 6670 suicide attempts and 347 suicides are projected among 7 − 17-year-olds from January 1, 2023, to early 2031 under the business-as-usual scenario. Mental health issues among 12 − 17-year-olds are projected to increase from 18.9% (2023) to 27.8% (2031), and substance use issues from 2.29 to 2.49% over the same period. School-based suicide prevention and gatekeeper training are the most effective strategies, reducing total numbers of suicide attempts and suicides by more than 20% (i.e., compared to business-as-usual). However, discontinuous funding significantly hinders these effective suicide prevention efforts. Conclusions: Systems modelling is an important tool for understanding where the best strategic financial and political investments lie for improving youth mental health in resource-constrained settings.

Background: Cervical cancer patients in Colombia have a lower likelihood of survival compared to breast cancer patients. In 1993, Colombia enrolled citizens in one of two health insurance regimes (contributory-private insurance and subsidized- public insurance) with fewer benefits in the subsidized regime. In 2008, the Constitutional Court required the Colombian government to unify services of both regimes by 2012. This study evaluated the impact of this insurance change on cervical cancer mortality before and after 2012. Methods: We accessed 24,491 cervical cancer mortality records for 2006–2020 from the vital statistics of Colombia's National Administrative Department of Statistics (DANE). We calculated crude mortality rates by health insurance type and departments (geopolitical division). Changes by department were analyzed by rate differences between 2006 and 2012 and 2013–2020, for each health insurance type. We analyzed trends using join-point regressions by health insurance and the two time-periods. Results: The contributory regime (private insurance) exhibited a significant decline in cervical cancer mortality from 2006 to 2012, characterized by a noteworthy average annual percentage change (AAPC) of -3.27% (P = 0.02; 95% CI [-5.81, -0.65]), followed by a marginal non-significant increase from 2013 to 2020 (AAPC 0.08%; P = 0.92; 95% CI [-1.63, 1.82]). In the subsidized regime (public insurance), there is a non-significant decrease in mortality between 2006 and 2012 (AAPC − 0.29%; P = 0.76; 95% CI [-2.17, 1.62]), followed by a significant increase from 2013 to 2020 (AAPC of 2.28%; P < 0.001; 95% CI [1.21, 3.36]). Examining departments from 2013 to 2020 versus 2006 to 2012, the subsidized regime showed fewer cervical cancer-related deaths in 5 out of 32 departments, while 6 departments had higher mortality. In 21 departments, mortality rates remained similar between both regimes. Conclusion: Improvement of health benefits of the subsidized regime did not show a positive impact on cervical cancer mortality in women enrolled in this health insurance scheme, possibly due to unresolved administrative and socioeconomic barriers that hinder access to quality cancer screening and treatment.

Background: This study explores the impacts of attacks perpetrated in the context of armed conflict, to female health workers in three Colombian territories. Methods: We conducted a document review of the reports and databases of the Colombian Truth Commission, 17 in-depth semi-structured interviews with experts on the national and regional armed conflict and the medical mission, and 26 female health workers who were victims of attacks. Results: Experts and female health workers reported attacks to health activities, facilities, equipment, and personnel, including attacks to traditional doctors belonging to indigenous communities. The most frequent attacks were threats and retention of health personnel; theft of supplies and medicines; damage and use of infrastructure and means of transport for purposes other than health care; and hinderance of health service provision. The attacks occurred in a framework of structural violence that intersects with poverty, racism, and gender bias. The impacts of these attacks include gender-based violence, significant disruption of the lives of health workers, and physical, emotional, psychological, social, and economic effects on the victims and their families. The government response to protect victims and populations has been absent or insufficient. Conclusions: Attacks to health care were reported in all the studied territories obstructing adequate health care. Impacts of these attacks affect negatively the professional and personal life of the workers and are aggravated by structural violence and absent or little institutional response.

Background: Conflict and violence can impact on the mental health of children and young people, who are in a crucial stage of their personal growth. Not much is known about the provision of mental health care to young people in conflict-affected areas. Community-based care can be essential, as state-led services are often scarce in conflict contexts, like Colombia's Pacific region where this research was conducted. According to the WHO, such care is ideally provided in the form of a network of interconnected services, offered by different actors beyond the formal health sector. This article describes the relationship between the formal and community mental health systems in Colombia's Pacific region, and identifies ways of improving their interaction. Methods: Qualitative data were collected through 98 semi-structured interviews with community organisations, schools, international organisations and state institutions. These interviews aimed to identify the strategies used to promote young people's mental health and the interactions between the different providers. Boundary spanning theory was used to analyse how different actors and forms of mental health care provision could coordinate better. Results: Community organisations and schools use a wide array of strategies to attend to the mental health of children and young people, often of a collective and psychosocial nature. State institutions offer more clinically focused strategies, which are however limited in terms of accessibility and continuity. International organisations aim to strengthen state capacity, but often struggle due to high staff turnover. Although mental health care pathways exist, their effectiveness is limited due to ineffective coordination between actors. Conclusions: To make sure that the variety of strategies to improve young people's mental health effectively reach their beneficiaries, better coordination is needed between the different actors. Mental health care pathways should therefore integrate community organisations, while community connectors can help to manage the coordination between different actors and forms of clinical and psychosocial support.

Colombia has one of the longest running internal armed conflicts, which has significantly impacted the mental health of the population. This article is the first to present a national level mapping of the provision of mental health services to young people living in Colombia, through detailed review of documentation, interviews with key stakeholders and quantitative analysis of existing data on mental health and suicide. It explores the existing public mental health provision in the country, focussing on where mental health resources are concentrated and how these are implemented. We use this mapping to understand how the current mental health system in Colombia fits with international approaches to youth mental health. We show that whilst mental health policy is variously framed (biomedical, biosocial, psychologically or through human rights), Colombian policy clearly focusses on a differential approach. This differential approach shapes service provision to target support at those in need, consequently neglecting whole population level mental health support. This means that not all stakeholders were clearly articulated or included in policy and that key institutional stakeholders, such as the education sector, were not linked to implementation plans or activity. Policy approaches were also over-centralised with little cross-institutional collaboration. Youth were specifically missing from services, as was explicit understanding of the intergenerational effects and impact of conflict. This was exacerbated by unequal distribution of mental health care services concentrated in populous, urban areas away from conflict-affected regions. Suicide is the second most prevalent cause of death with 10% of population who were recorded as dying by violence, dying from completed suicide. Triangulation implies a strong relationship between suicide and poorer access to professional support in conflict-affected areas and suggests that international frameworks and policy approaches to supporting youth mental health have been insufficiently adapted for conflict and post conflict contexts.

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. [ABSTRACT FROM AUTHOR]

Background Malaria is a serious health problem in Colombia. This paper intends to analyse the frequency and tendencies of the disease in Colombia over the last 22 years. The researchers used the Box-Jenkins (ARIMA) methodology for the analysis of time series. Methods This descriptive study was done retrospectively by using the morbidity records of the Ministry of Health and of the System for the Monitoring of Public Health (SIVIGILA). The information about the population was obtained from the National Administrative Department of Statistics (DANE). The incidence rate according to age and sex was calculated from 1990 to 2011. Also, the Annual Parasite Index (API) for Plasmodium falciparum and for Plasmodium vivax was calculated. The mortality rates per year, from 1990 to 2011, were determined. Finally, the Box-Jenkins (ARIMA) methodology was used for the analysis of time series, grouped weekly. Information for ARIMA modelling was used from the year 2001. Results The total number of reported cases from 1990 to 2012 was 2,964,818 cases with an annual average of 134,764. In the period from 2001 to 2005 and from 2006 to 2011 a significant decrease of annual cases was observed. In general, a predominance of P. vivax over P. falciparum was observed. With respect to the API, it must be noted that there were peaks in 1994 in the departments of Guainía and Guaviare, and in 1998 in Guaviare and Chocó. The department of Antioquia showed a tendency towards a decrease of the API through the years. In the time series model there were no statistically significant seasonal patterns for the total number of cases of malaria. However, for P. falciparum the number of cases was statistically significant. Lastly, between 1990 and 2009, there were 1,905 deaths caused by malaria in Colombia with a significant tendency towards a decrease in deaths over those years. Plasmodium falciparum was more lethal than P. vivax. Conclusions In Colombia, the transmission of malaria occurs in an endemic and epidemic context, which keeps an unstable endemic transmission pattern. Several factors specific to a country such as Colombia encourage the dissemination and permanence of the illness. [ABSTRACT FROM AUTHOR]

Background: Colombia has experienced decades of conflict between the government and non-state actors. Attacks on healthcare have been a grave but regular facet of that violence. In response, the Misión Médica (MM) program was developed to support, protect, and defend healthcare. Sporadic violence continues, with many recent attacks perpetrated not by armed actors but by residents. Given the history of conflict and ongoing violence, we sought to capture the perspectives of both healthcare workers (HCWs) and community members (CMs) regarding the characteristics and impacts of attacks on health in Colombia to gain insight into how to better prevent violence and mitigate its impacts. Methods: A cross-sectional survey was conducted from January to March 2021 in seven departments in Colombia in regions that witnessed attacks on healthcare. Questionnaires were administered to HCWs and CMs via purposive sampling, probing their experiences with attacks on health with both closed and open-ended questions. The categorical responses were stratified by health worker vs. non-health worker and descriptively analyzed. Narrative responses were analyzed via a hybrid deductive/inductive thematic approach. Results: Seventy-three individuals participated in the study (36 HCWs and 37 cm). Approximately 77% of HCWs believed that attacks on healthcare impacted health outcomes while 68% of CMs did not see a direct connection between violence against healthcare and poor health outcomes. Awareness of the MM program was significantly different between HCWs (83.3%) and CMs (37.8%). The survey responses explored the characteristics of attacks on health, compounded impacts of violence on the health system, personal impacts, and perspectives on mitigation efforts. Conclusions: The study demonstrates that: (1) attacks on healthcare are context-dependent and require a local lens for mitigation and management; (2) both HCWs and CMs have critical perspectives that must be considered, (3) the impacts of violence against healthcare are complex and compounded and (4) that awareness of the legal protections of the Geneva Conventions must be combined with education on the health impacts for robust protection strategies. Critically, Both CMs and HCWs experience fear and psychosocial ramifications of these attacks, suggesting the need for stronger protections and resources to support the health workforce and the local community.

Background: Self-efficacy alludes to personal competence in an individual's effectiveness when facing stressful situations. This construct has been related to different domains of the health field, finding that high levels of self-efficacy benefit human functioning and enhance well-being. Methods: The present study aimed to determine the psychometric properties of the self-efficacy scale for managing chronic diseases (SEMCD-S) by assessing factorial, convergent and divergent validity, reliability, and measurement invariance. Likewise, the comparison of self-efficacy according to socio-demographic characteristics was proposed by contrasting latent factors. An instrumental, transactional, descriptive, and non-experimental design study was carried out with the participation of 325 Colombian senior citizens. Results: The findings suggest that the scale has appropriate psychometric properties. The one-factor structure exhibited a satisfactory fit, the mean-variance extracted reported acceptable figures and the correlation analysis with other constructs supported this instrument's convergent and discriminant validity. Likewise, it was invariant to the different socio-demographic aspects examined, while the internal consistency figures were high. Differences in the means of the latent factors were only detected in the academic grade. In this case, older adults with a primary school level attained higher self-efficacy values than those who had completed high school or university studies. Conclusions: It is concluded that the self-efficacy scale for chronic disease management is a valid and reliable instrument that can be used in the Colombian context to measure and compare this construct.

Introduction: Colombia has 50,912,429 inhabitants, but only 50–70% of the population can effectively access health care services. The emergency room (ER) is a main contributor to the in-hospital care system since up to half of the admissions come through it. Telemedicine has become a tool to facilitate effective access to health care services, improve the timeliness of care, reduce diagnostic variability, and reduce costs associated with health. The aim of this study is to describe the experience of a Distance Emergency Care Program through Telemedicine (TelEmergency) to improve specialist access for patients at the Emergency Room (ER) in low- and medium-level care hospitals in Colombia. Methods: An observational descriptive study of a cohort including 1,544 patients during the program's first two years was conducted. Descriptive statistics were used to analyze the available data. The data are presented with summarized statistics of sociodemographic, clinical, and patient-care variables. Results: The study included a total of 1,544 patients, and the majority were adults between 60 and 79 years of age (n = 491, 32%). More than half were men (n = 832, 54%), and 68% (n = 1,057) belonged to the contributory health care regime. The service was requested from 346 municipalities, 70% (n = 1,076) from intermediate and rural settings. The most common diagnoses were related to COVID-19 (n = 356, 22%), respiratory diseases (n = 217, 14%), and cardiovascular diseases (n = 162, 10%). We observed 44% (n = 681) of local admissions either under observation (n = 53, 3%) or hospitalization (n = 380, 24%), limiting the need for hospital transfers. Program operation data revealed that 50% (n = 799) of requests were answered within two hours by the medical staff. The initial diagnosis was modified in 7% (n = 119) of the patients after being evaluated by specialists at the TelEmergency program. Conclusions: This study shows the operational data collected during the first two years after the implementation of the TelEmergency program in Colombia, the first of its kind in the country. Its implementation offered specialized timely management of patients at the ER in low- and medium-level care hospitals, where there is no availability of specialized doctors. [ABSTRACT FROM AUTHOR]

Mixed methods are essential in public health research and malaria control, because they allow grasping part of the complexity and diversity of the factors that determine health-disease. This study analyzes the mixed studies on malaria in Colombia, 1980–2022, through a systematic review in 15 databases and institutional repositories. The methodological quality was assessed with Mixed Methods Appraisal Tool (MMAT), STrengthening the Reporting of OBservational studies in Epidemiology (STROBE), and Standards for Reporting Qualitative Research (SRQR). The qualitative and quantitative findings were grouped into a four-level hierarchical matrix. The epidemiological profile of malaria morbidity, from traditional epidemiology, has been sustained by environmental problems, armed conflict, individual risk behaviors, and low adherence to recommendations from health institutions. However, the qualitative component reveals deeper causes that are less studied, of greater theoretical complexity, and that reflect challenges to design and implement health interventions, such as socioeconomic and political crises, poverty, and the neoliberal orientation in the malaria control policy; the latter reflected in the change in the role of the State, the fragmentation of control actions, the predominance of insurance over social assistance, the privatization of the provision of health services, the individualistic and economistic predominance of health, and low connection with popular tradition and community initiatives. The above confirms the importance of expanding mixed studies as a source of evidence to improve malaria research and control models in Colombia, and to identify the underlying causes of the epidemiological profile.

Background: The Colombian armed conflict has left millions of victims and has restricted access to different services provided by the government, especially for people with disabilities. This article studies the barriers faced by the victim population with disabilities when they want to access the health system in the department of Meta, Colombia, and offers a perspective from the experiences of people with disabilities who have been victims of the armed conflict in the country. Methods: To carry out this qualitative study, focus groups were conducted to capture the experiences and feelings of this population in the context of violence and high conflict. Results: The results show the barriers encountered by the victim population with disabilities, their families, and their caregivers when they want to access medical or health services. Conclusions: Many problems affect the population with disabilities and the victim population in Colombia today. The Colombian government has not been able to establish adequate policies to eliminate or even reduce access to services such as health, education, housing, and social protection. Key message: • The population with disabilities who have been victims of the armed conflict in Colombia find more significant barriers to accessing health services than people without disabilities due to various situations of exclusion in the provision and accessibility of medical services. • In the department of Meta, the population with disabilities who have been victims of the armed conflict manifest being vulnerable and lacking protection from the Colombian government. • Colombia, to date, has not been able to fully implement national and international agreements that guarantee respect for the human rights of people with disabilities. • It is essential that both national and local governments implement policies and actions so that the victim population with disabilities can access health, education, and social protection services.

Background: Cultural safety training, whereby health professionals learn to reflect on their own culture and to respect the cultural identity of patients, could address intercultural tensions in health care. Given the context of their medical education, however, medical students might perceive such training to be dull or even unnecessary. Game jams, collaborative workshops to create and play games, are a potentially engaging learning environment for medical students today. How medical students learn while making games is poorly documented. This study describes the characteristics of educational games created by participants in a cultural safety game jam and the concepts they used to create games. Methods: As part of a trial, 268 Colombian medical students divided into 48 groups participated in an eight-hour game jam to create a prototype of an educational game on cultural safety. In this qualitative descriptive study, we reviewed the description of the games uploaded by participants, including the name, objective, game narrative, rules, rewards, penalties, and pictures. An inductive thematic analysis collated their descriptions. Results: The game descriptions illustrated the characteristics of the educational games and the aspects of the cultural safety concept that the students used to create games. Medical students situated cultural safety within a continuum with culturally unsafe actions at one end and cultural safety at the other end. Although not familiar with game design, the students designed prototypes of basic educational games including game dynamics, game scenarios, learning objectives, and pedagogical strategies. Conclusion: The findings of this study could help researchers and educators to understand how medical students learn from game design and the kind of games that game jam participants can create without previous game design skills.

Background: Resistance to anti-malarial drugs is associated with polymorphisms in target genes and surveillance for these molecular markers is important to detect the emergence of mutations associated with drug resistance and signal recovering sensitivity to anti-malarials previously used. Methods: The presence of polymorphisms in genes associated with Plasmodium falciparum resistance to chloroquine and sulfadoxine-pyrimethamine was evaluated by Sanger sequencing, in 85 P. falciparum day of enrollment samples from a therapeutic efficacy study of artemether–lumefantrine conducted in 2018–2019 in Quibdo, Colombia. Samples were genotyped to assess mutations in pfcrt (codons 72–76), pfdhfr (codons 51, 59, 108, and 164), and pfdhps genes (codons 436, 437, 540, and 581). Further, the genetic diversity of infections using seven neutral microsatellites (NMSs) (C2M34, C3M69, Poly α, TA1, TA109, 2490, and PfPK2) was assessed. Results: All isolates carried mutant alleles for pfcrt (K76T and N75E), and for pfdhfr (N51I and S108N), while for pfdhps, mutations were observed only for codon A437G (32/73, 43.8%). Fifty samples (58.8%) showed a complete neutral microsatellites (NMS) profile. The low mean number of alleles (2 ± 0.57) per locus and mean expected heterozygosity (0.17 ± 0.03) showed a reduced genetic diversity. NMS multilocus genotypes (MMG) were built and nine MMG were identified. Conclusions: Overall, these findings confirm the fixation of chloroquine and pyrimethamine-resistant alleles already described in the literature, implying that these drugs are not currently appropriate for use in Colombia. In contrast, mutations in the pfdhps gene were only observed at codon 437, an indication that full resistance to sulfadoxine has not been achieved in Choco. MMGs found matched the clonal lineage E variant 1 previously reported in northwestern Colombia. [ABSTRACT FROM AUTHOR]
