RESUMEN
Influenza A viruses (IAV) impose significant respiratory disease burdens in both swine and humans worldwide, with frequent human-to-swine transmission driving viral evolution in pigs and highlighting the risk at the animal-human interface. Therefore, a comprehensive One Health approach (interconnection among human, animal, and environmental health) is needed for IAV prevention, control, and response. Animal influenza genomic surveillance remains limited in many Latin American countries, including Colombia. To address this gap, we genetically characterized 170 swine specimens from Colombia (2011-2017). Whole genome sequencing revealed a predominance of pandemic-like H1N1 lineage, with a minority belonging to H3N2 and H1N2 human seasonal-like lineage and H1N1 early classical swine lineages. Significantly, we have identified reassortant and recombinant viruses (H3N2, H1N1) not previously reported in Colombia. This suggests a broad genotypic viral diversity, likely resulting from reassortment between classical endemic viruses and new introductions established in Colombia's swine population (e.g. the 2009 H1N1 pandemic). Our study highlights the importance of a One Health approach in disease control, particularly in an ecosystem where humans are a main source of IAV to swine populations, and emphasizes the need for continued surveillance and enhanced biosecurity measures. The co-circulation of multiple subtypes in regions with high swine density facilitates viral exchange, underscoring the importance of monitoring viral evolution to inform vaccine selection and public health policies locally and globally.

Equine influenza is a viral disease caused by the equine influenza virus (EIV), and according to the WOAH, it is mandatory to report these infections. In Latin America and Colombia, EIV risk factors have not been analyzed. The objective of this research is to perform an epidemiological and molecular analysis of the EIV in horses with respiratory symptoms from 2020 to 2023 in Colombia. Molecular EIV detection was performed using RT-qPCR and nanopore sequencing. A risk analysis was also performed via the GEE method. A total of 188 equines with EIV respiratory symptoms were recruited. The positivity rate was 33.5%. The descriptive analysis showed that only 12.8% of the horses were vaccinated, and measures such as the quarantine and isolation of symptomatic animals accounted for 91.5% and 88.8%, respectively. The variables associated with the EIV were the non-isolation of positive individuals (OR = 8.16, 95% CI (1.52-43.67), p = 0.014) and sharing space with poultry (OR = 2.16, 95% CI (1.09-4.26), p = 0.027). In conclusion, this is the first EIV investigation in symptomatic horses in Colombia, highlighting the presence of the virus in the country and the need to improve preventive and control measures.

Seven novel porcine parvoviruses (nPPVs) (PPV2 through PPV8) have been described, although their pathogenicity and possible effects on porcine reproductive failure (PRF) are undefined. In this study, these nPPVs were assessed in gilts from Colombia; their coinfections with PPV1, PCV2, PCV3, PCV4, and PRRSV and an association between the nPPVs and the reproductive performance parameters (RPPs) in sows were determined. For this, 234 serum samples were collected from healthy gilts from 40 herds in five Colombian regions, and the viruses were detected via real-time PCR. The results confirmed the circulation of PPV2 through PPV7 in Colombia, with PPV3 (40%), PPV5 (20%), and PPV6 (17%) being the most frequent. Additionally, no PCV4 or PPV8 was detected. PPV2 to PPV7 were detected in concurrence with each other and with the primary PRF viruses, and these coinfections varied from double to sextuple coinfections. Additionally, the association between nPPVs and PRF primary viruses was statistically significant for the presence of PPV6 in PCV3-positive (p < 0.01) and PPV5 in PPRSV-positive (p < 0.05) gilts; conversely, there was a significant presence of PPV3 in both PCV2-negative (p < 0.01) and PRRSV-negative (p < 0.05) gilts. Regarding the RPPs, the crude association between virus detection (positive or negative) and a high or low RPP was only statistically significant for PCV3 and the farrowing rate (FR), indicating that the crude odds of a low FR were 94% lower in herds with PCV3-positive gilts. This finding means that the detection of PCV3 in gilts (PCV3-positive by PCR) is associated with a higher FR in the farm or that these farms (with positive gilts) have lower odds (OR 0.06, p-value 0.0043) of a low FR. Additionally, a low FR tended to be associated with the detection of PPV4 and PPV5 (p-value < 0.20). This study is important for establishing the possible participation of nPPVs in PRF.
RESUMEN
Austrian syndrome corresponds to the triad of meningitis, pneumonia, and endocarditis caused by Streptococcus pneumoniae, there is no global or local incidence given the infrequency of entity. Scarce cases are published in Latin America, with none of them in Colombia. A case of Austrian syndrome by penicillin-resistant S. pneumoniae in an immunocompetent patient is presented. Aortic valve is the most frequent site involved in Austrian syndrome; this patient had an unusual localization of the vegetation on the right coronary artery ostium. The prognosis is poor with a mortality rate of 30% or higher, this patient survived despite systemic complications. Vaccination status impacts in prevention and severity of cases because responsible serotypes are often included in available vaccines. The patient had a serotype covered by available vaccines; however, her vaccination status was unknown. Thus, we present the first case reported in Colombia of Austrian syndrome by a penicillin-resistant S. pneumoniae, in a patient with no identified comorbidities or toxicological history, with a successful evolution.
RESUMEN
La cromoblastomicosis es una micosis subcutánea crónica de presentación clínica heterogénea que afecta principalmente a poblaciones de escasos recursos, lo que sumado al acceso limitado a los servicios de salud condiciona el retraso en el diagnóstico y tratamiento, ocasionando secuelas físicas graves. Se describe el caso de un hombre de 50 años con lesiones cutáneas verrugosas y cicatriciales de 30 años de evolución en la extremidad inferior y mano izquierda, además en cara en los últimos cinco años. Se realizó el diagnóstico de cromoblastomicosis de presentación multifocal y clínica mixta, con examen directo e histopatología compatibles, y cultivo para hongos positivo para Fonsecaea pedrosoi. Se indicó tratamiento oral con itraconazol y seguimiento clínico. Reconocer esta entidad es crucial para un diagnóstico y tratamiento oportunos, con el fin de evitar secuelas físicas y estigmatización secundaria. Se debe fortalecer en la atención primaria el reconocimiento de patologías desatendidas y de incidencia subestimada en Colombia, con una presentación multifocal mixta atípica y de un tiempo de evolución prolongado. El examen directo KOH es un herramienta accesible y económica en los primeros niveles de atención que puede contribuir al enfoque diagnóstico.
Chromoblastomycosis is a chronic subcutaneous mycosis with heterogeneous clinical presentation. It mainly affects low-income populations, which added to limited access to health services delays diagnosis and treatment, causing serious physical sequelae. We describe the case of a 50-year-old man with warty and cicatricial skin lesions of 30 years of evolution, at the level of left lower limb and left hand, with face involvement in the last five years. A diagnosis of chromoblastomycosis with multifocal and mixed clinical presentation was made, based on compatible direct examination and histopathology, and positive fungal culture for Fonsecaea pedrosoi. Oral treatment with itraconazole and clinical followup were stablished. Recognizing this entity is crucial for timely diagnosis and treatment, to avoid physical sequelae and secondary stigmatization. Primary health care should be strengthened for the recognition of neglected diseases whose incidence is underestimated in Colombia, with an atypical mixed multifocal presentation and a long evolution time. The KOH direct examination is an accessible and economical tool in the first levels of care that can contribute to the diagnostic approach.

Mozambique is one of the four African countries which account for over half of all malaria deaths worldwide, yet little is known about the parasite genetic structure in that country. We performed P. falciparum amplicon and whole genome sequencing on 2251 malaria-infected blood samples collected in 2015 and 2018 in seven provinces of Mozambique to genotype antimalarial resistance markers and interrogate parasite population structure using genome-wide microhaplotyes. Here we show that the only resistance-associated markers observed at frequencies above 5% were pfmdr1-184F (59%), pfdhfr-51I/59 R/108 N (99%) and pfdhps-437G/540E (89%). The frequency of pfdhfr/pfdhps quintuple mutants associated with sulfadoxine-pyrimethamine resistance increased from 80% in 2015 to 89% in 2018 (p < 0.001), with a lower expected heterozygosity and higher relatedness of microhaplotypes surrounding pfdhps mutants than wild-type parasites suggestive of recent selection. pfdhfr/pfdhps quintuple mutants also increased from 72% in the north to 95% in the south (2018; p < 0.001). This resistance gradient was accompanied by a concentration of mutations at pfdhps-436 (17%) in the north, a south-to-north increase in the genetic complexity of P. falciparum infections (p = 0.001) and a microhaplotype signature of regional differentiation. The parasite population structure identified here offers insights to guide antimalarial interventions and epidemiological surveys.

Background: Acute intermittent porphyria (AIP) is an uncommon metabolic disease, being the most common of the acute porphyrias. The most frequent symptom is acute abdominal pain, although can be accompanied by seizures, neuro-psychiatric alterations or symmetrical motor neuropathies, which in some patients can progress to respiratory musculature paralysis. Objective: To describe an atypical presentation of acute porphyria to be considered as differential diagnoses in abdominal pain. Clinical case: We present a case of a patient with AIP, presenting acute abdomen, seizures, later developed neuropsychiatric compromise and symmetrical motor neuropathy, and was admitted to mechanical ventilation. Due to the severity of the neurological involvement, he received hemin arginate, presenting with transient hypertransaminemia, an adverse event not previously reported. The evolution was favorable, with mechanical ventilation and hospital discharge withdrawn. Conclusions: The diagnosis of AIP should be considered in cases of acute abdominal pain associated with neurological and/or psychiatric symptoms, particularly young women. The administration of hemin is considered the standard of treatment, and even late could have beneficial effects.
Introducción: la porfiria aguda intermitente (PAI) es una enfermedad metabólica infrecuente, siendo la más común de las porfirias agudas. El síntoma más frecuente es el dolor abdominal agudo, aunque también pueden acompañarse de convulsiones, alteraciones neuro-psiquiátricas o neuropatías motoras simétricas, y que en algunos pacientes puede progresar a la parálisis de la musculatura respiratoria. El objetivo de este trabajo es describir una forma atípica de presentación de una porfiria aguda, a fin de considerar como diagnósticos diferenciales en dolor abdominal. Caso clínico: paciente con PAI, que presenta abdomen agudo, convulsiones, posteriormente compromiso neuro-psiquiátrico y neuropatía motora simétrica, ingresando a ventilación mecánica. Por la gravedad del compromiso neurológico recibió arginato de hemina, cursando con hipertransaminemia transitoria, evento adverso no reportado previamente. La evolución fue favorable, retirándosele la ventilación mecánica y el alta hospitalaria. Conclusiones: se debe considerar el diagnóstico de PAI en casos de dolor abdominal agudo asociado a síntomas neurológicos y/o psiquiátricos, particularmente en mujeres jóvenes. La administración de hemina es considerada el estándar de tratamiento, y aun en forma tardía podría tener efectos beneficiosos.

Malakoplakia is a rare granulomatous inflammatory disorder. Its diagnosis depends on histopathological findings; however, high-quality literature regarding proper medical/surgical treatment is lacking. A 38-year-old diabetic female patient was admitted to the emergency room with a history of lower gastrointestinal hemorrhage. Colonoscopy revealed a lesion in the descending colon, and abdominal computed tomography revealed a splenic flexure mass involving the lower pole of the spleen and upper pole of the left kidney. Biopsies confirmed the diagnosis of malakoplakia. After completing antibiotic treatment, a restaging computed tomography revealed a discrete mass increase; hence, the patient underwent laparoscopic en bloc colectomy and partial nephrectomy. Postoperatively, the patient developed a pancreatic fistula, which was successfully treated with percutaneous drainage and antibiotics. The presence of pathognomonic Michaelis-Gutmann inclusions on histopathology is frequently reported as the key to diagnosing malakoplakia. Herein, we present a successful, minimally invasive surgical treatment for colonic malakoplakia.
RESUMEN
Biosecurity protocols (BP) and good management practices are key to reduce the risk of introduction and transmission of infectious diseases into the pig farms. In this observational cross-sectional study, survey data were collected from 176 pig farms with inventories over 100 sows in Colombia. We analyzed a complex survey dataset to explore the structure and identify clustering patterns using Multiple Correspondence Analysis (MCA) of swine farms in Colombia, and estimated its association with Influenza A virus detection. Two principal dimensions contributed to 27.6% of the dataset variation. Farms with highest contribution to dimension 1 were larger farrow-to-finish farms, using self-replacement of gilts and implementing most of the measures evaluated. In contrast, farms with highest contribution to dimension 2 were medium to large farrow-to-finish farms, but implemented biosecurity in a lower degree. Additionally, two farm clusters were identified by Hierarchical Cluster Analysis (HCA), and the odds of influenza A virus detection was statistically different between clusters (OR 7.29, CI: 1.7,66, p = < 0.01). Moreover, after logistic regression analysis, three important variables were associated with higher odds of influenza detection: (1) "location in an area with a high density of pigs", (2) "farm size", and (3) "after cleaning and disinfecting, the facilities are allowed to dry before use". Our results revealed two clustering patterns of swine farms. This systematic analysis of complex survey data identified relationships between biosecurity, husbandry practices and influenza status. This approach helped to identify gaps on biosecurity and key elements for designing successful strategies to prevent and control swine respiratory diseases in the swine industry.
RESUMEN
INTRODUCTION: Although more than half of the world's population is already vaccinated, the appearance of new variants of concern puts public health at risk due to the generation of new immunogens against the virus as a crucial and relevant strategy in the control of these new variants. METHODS: A preclinical study used a potential vaccine candidate (RBD, SARS-CoV-2). Four groups of BALB/c mice were used, a control group, an adjuvant group, a group inoculated with one dose of RBD subunit protein, and the fourth group inoculated with two doses of RBD subunit protein. RESULTS: No inflammatory or cellular changes were shown in the mice's anatomopathological evaluation. Higher kinetics and 75% seroconversion were obtained in the mice inoculated with two doses of RBD (Pâ¯<â¯0.0001). CONCLUSIONS: The application of two doses of the RBD vaccine candidate in BALB/c mice proved safe and immunogenic against SARS-CoV-2.

Background: Tick-borne diseases (TBD) and dirofilariosis are currently not under surveillance in most Latin American countries. In addition, there is a significant lack of studies describing the current situation in most endemic areas, including Colombia. Therefore, seroprevalence studies are crucial for understanding the epidemiology of these vector-borne diseases. Methods: A serosurvey for TBD and dirofilariosis among 100 dogs was carried out in the municipality of Pereira, located in the Coffee-Triangle region, Colombia. Samples were tested using a rapid assay test system (SNAP® 4Dx®); based on an enzyme immunoassay technique' screening for antibodies to Anaplasma phagocytophilum/platys (sensitivity 99.1%)' Borrelia burgdorferi s.l. (98.8%), and Ehrlichia canis/ewingii (96.2%) by using specific antigens and checking for Dirofilaria immitis antigen based on specific antibodies (99.2%). Bivariate analyses were performed on Stata®14, significant p < 0.05. Findings: Global seroprevalence to the selected vector-borne pathogens was 74% (95%CI 65-83%). The highest seroprevalence was found for E. canis/ewingii (74%), followed by A. phagocytophilum/platys (16%). Seropositivity for Borrelia spp. and Dirofilaria spp. was 0%. All Anaplasma spp. seropositive dogs showed co-detection of Ehrlichia spp. (16%). Seroprevalence was significantly higher among dogs from families of lower socioeconomic status/level (I, 86%), followed by level II (74%), and III (36%) (p = 0.001). All dogs exhibiting anorexia (12%) were invariably seropositive (100%) (p = 0.029). Seroprevalence was higher among those showing mucocutaneous paleness (95%) compared to those without paleness (68%) (p = 0.013) (OR = 9.3; 95%CI 1.18-72.9). There was high variability in seroprevalence through the studied areas, ranging from 0% (La Libertad Park) up to Combia, Cesar Nader, Las Brisas and Saturno localities (100%) (p = 0.033). Interpretation: Given the high seroprevalence obtained in an area with documented ticks, there is a potential risk of zoonotic transmission to humans. Further seroprevalence studies in humans are needed to assess the prevalence of infections. Poverty is highly associated with these tick-borne pathogens in Pereira, as shown in the present study.
RESUMEN
Staphylococcus aureus remains a pathogen of high concern in public health programs worldwide due to antibiotic resistance and emergence of highly virulent strains. Many phytochemicals have demonstrated activity against S. aureus and other Gram-positive bacteria, but the minimum inhibitory concentration (MIC) values comparable to commonly used antibiotics are needed. In the present study, bio-guided fractionation of the ethanol extract of seeds of Mammea americana L. (Calophyllaceae) throughout the antibacterial activity, against S. aureus strains that are sensitive and resistant to methicillin, led to the isolation of four coumarins identified as mammea B/BA, mammea B/BC, mammea A/AA cyclo D and mammea A/AA cyclo F, and a mixture of mammea B/BA cyclo F plus mammea B/BD cyclo F. The extract inhibited the growth of S. aureus with MIC values of 2-4 µg/ml and Mammea B/BA (MaBBA) presented MIC values in a range between 0.5 and 1.0 µg/ml in six methicillin-sensitive strains and eight methicillin-resistant strains evaluated. We consider MaBBA the most potent of all mammea coumarins reported to date, according to the literature review carried out at the time of writing of this article. Toxicity assessment in vivo against the nematode Caenorhabditis elegans and in vitro against human fibroblasts of the extract and the compound MaBBA indicated that both had low toxicity.
RESUMEN
Background: Chagas cardiomyopathy (CC) increases cardiovascular mortality associated with congestive heart failure (CHF), ventricular arrhythmias (VA), and sudden cardiac death (SCD). Different imaging techniques have been tested to assess disease progression and cardiac risk in individuals with Chagas disease (ChD). In this systematic review, we evaluated the accuracy in detecting cardiac complications in CC patients using cardiac magnetic resonance (CMR) and speckle tracking echocardiography (STE). Methods: A search was done on PubMed, Cochrane, and Embase for studies in humans over 18 years of age with ChD. Demographic data, research methodology, imaging parameters, and cardiac outcomes were extracted, and study quality was assessed, resulting in a narrative description. Results: Twelve studies with 1124 patients were analyzed. One study discovered a contractility pattern by STE. Four studies assessed the identification of Early Cardiac Impairment (ECI) and VA risk, respectively, while three studies evaluated the risk of SCD. Global Longitudinal Strain (GLS) identified patients with ECI (-18.5 ± 3.4% non-fibrosis vs -14.0 ± 5.8% fibrosis, p = 0.006 and -18 ± 2% non-fibrosis vs -15 ± 2% fibrosis, p = 0.004). The amount of fibrosis > 11.78% or in two or more contiguous transmural segments were markers for VA risk. GLS and the amount of fibrosis were found to be predictors of SCD. Conclusions: STE may be considered a screening technique for identifying the subclinical status of CHF. CMR using Late Gadolinium Enhancement (LGE) is considered a relevant parameter for stratifying patients with ChD who are at risk of SCD. Fibrosis and GLS can be used as markers to categorize patients at risk for arrhythmias.
RESUMEN
Este documento está centrado en determinar qué variables afectan los incentivos que tienen los delincuentes al cometer sus ciberdelitos, e identificar si la legislación actual está diseñada teniendo en cuenta la tipificación de las conductas y las herramientas de los entes encargados de capturar los criminales. Se busca entender los principales factores que incentivan la ciberdelincuencia en el país, teniendo en cuenta el contexto de la ciberdelincuencia para el 2019 en Colombia, y con ello, el comportamiento de los delincuentes informáticos en la prepandemia. Con la Ley 1273 de 2019, encargada de tipificar los delitos informáticos en Colombia, se revisarán los datos reportados de delitos informáticos y se compararán con los casos e indicadores de delitos de hurto calificado, con el fin de determinar la relación de estos dos delitos, que son relevantes para las entidades y han sido interiorizados por las entidades policivas en su estudio y lucha anticriminal desde hace mucho tiempo. Una vez definida teóricamente la eficiencia de las entidades apoderadas en la lucha contra los delitos informáticos, se propone una función de beneficios económicos de la ciberdelincuencia adaptada para el caso colombiano, determinando las variables que mejor explican esta función. Al final de este ejercicio académico, mediante un análisis de sensibilidad, se señala qué aspectos de política pública se deben considerar como prioritarios, teniendo en cuenta los incentivos económicos para los ciberdelincuentes y la efectividad de la Ley 1273 de 2009.
This paper is focused on determining which variables affect the incentives that criminals have when committing cybercrime, and identify whether the current legislation is designed taking into account the criminalization of behaviors and the tools of the entities in charge of catching criminals. It seeks to understand the main factors that encourage cybercrime in the country, taking into account the context of cybercrime for 2019 in Colombia, and with it, the behavior of cybercriminals in the pre-pandemic. With Law 1273 of 2019, in charge of criminalizing computer crimes in Colombia, the reported data of computer crimes will be reviewed and compared with the cases and indicators of qualified theft crimes, in order to determine the relationship of these two crimes, which are relevant for the entities and have been internalized by the police entities in their study and anti-crime fight for a long time. Once the efficiency of the entities empowered in the fight against cybercrime has been theoretically defined, a function of economic benefits of cybercrime adapted to the Colombian case is proposed, determining the variables that best explain this function. At the end of this academic exercise, through a sensitivity analysis, it is pointed out which aspects of public policy should be considered as a priority, taking into account the economic incentives for cybercriminals and the effectiveness of Law 1273 of 2009.

Antecedentes: El trauma ocular secundario a deportes y actividades recreativas, incluyendo el paintball, es cada vez más frecuente, dejando secuelas a nivel anatómico y funcional irreversibles y en la mayoría de los casos podría prevenirse con el uso de dispositivos de protección ocular. Objetivo: Describir las características de los pacientes con diagnóstico de trauma ocular por paintball en el Hospital de San José entre 2010 y 2018. Materiales y métodos: Estudio retrospectivo. Se revisaron historias clínicas de pacientes con diagnóstico de trauma ocular por paintball entre los años 2010-2018. Resultados: Trece pacientes con diagnóstico de trauma ocular por paintball; nueve eran hombres y cuatro mujeres, con rango de edad de 9-58 años. La agudeza visual posterior al tratamiento en la mayoría mejoró con respecto a la visión inicial. La mayoría tuvo compromiso de segmento anterior y posterior y ocho requirieron manejo quirúrgico para restablecer la anatomía ocular. Conclusión: Las lesiones oculares por trauma con bolas de paintball generan secuelas importantes con mal pronóstico visual y anatómico. La recuperación de la agudeza visual depende de la extensión y severidad del trauma, pudiendo recuperarla en casos leves.
Background: Ocular trauma secondary to sports and recreational activities, including paintball, is very frequent, leaving irreversible anatomical and functional sequelae, in the most cases could be prevented with the use of eye protection. Objective: To describe the characteristics of patients diagnosed with paintball eye trauma at the Hospital de San José between 2010 and 2018. Materials and methods: Retrospective study, we reviewed the medical records of patients diagnosed with paintball eye trauma between the years 2010-2018. Results: Thirteen patients diagnosed with paintball eye trauma; nine were men and four were women, with an age range of 9-58 years. Visual acuity after treatment in the majority improved with respect to initial vision. Most had anterior and posterior segment involvement and eight required surgical management to restore ocular anatomy. Conclusion: Eye injuries due to paintball trauma generate important sequelae with poor visual and anatomical prognosis. The recovery of visual acuity depends on the extent and severity of the trauma, being able to recover it in mild cases
