RESUMEN
INTRODUCTION: Health challenges in the 21st century underscore the need for adaptable and innovative approaches in public health. Academic institutions can and should contribute much more effectively to generate and translate scientific knowledge that will result in better programmes to improve societal health. Academic accountability to local communities and society requires universities to actively engage with local communities, understanding the context, their needs, and leveraging their knowledge and local experience. The Programme Science initiative provides a framework to optimize the scale, quality and impact of public health programmes, by integrating diverse approaches during the iterative cycle of research and practice within the strategic planning, programme implementation and programme management and evaluation. We illustrate how the Programme Science framework could be a useful tool for academic institutions to accomplish accountability to local communities and society through the experience of Project HOPE in Peru. DISCUSSION: Project HOPE applied the Programme Science framework to introduce HPV self-sampling into a women's health programme in Peru. Collaboration with local authorities and community members was pivotal in all phases of the project, ensuring interventions aligned with community needs and addressing social determinants of health. The HOPE Ladies-community women trained and empowered to promote and provide the HPV kits-crafted the messages used through the study and developed strategies to reach individuals and provided support to women's journey through health centres. By engaging communities in co-creating knowledge and addressing health inequities, academic institutions can generate contextually relevant and socially just scientific knowledge. The active participation of community women in Project HOPE was instrumental in improving service utilization and addressing barriers to self-sampling. CONCLUSIONS: The Programme Science approach offers a pathway for academic institutions to enhance their accountability to communities and society at large. By embedding researchers within public health programmes and prioritizing community engagement, academic institutions can ensure that research findings directly inform policy improvements and programmatic decisions. However, achieving this requires a realignment of research agendas and recognition of the value of community engagement. Establishing Programme Science networks involving academia, government and funding entities can further reinforce academic accountability and enhance the impact of public health programmes.

BACKGROUND: Educational settings are ideal for promoting mental well-being and resilience in children. The challenges of the COVID-19 pandemic made evident the important role that teachers and school counselors play in the mental health of their students. Therefore, it is imperative to develop and implement cost-effective interventions that allow them to identify and address mental health problems early, especially in post-armed conflict areas, to reduce the burden of mental disorders in this population. OBJECTIVE: This study aimed to adapt an existing patient-focused digital intervention called DIALOG+ from an adult clinical setting to an adolescent educational setting and to assess the feasibility, acceptability, and estimated effect of implementing this intervention as a tool for promoting quality of life, mental well-being, and resilience. METHODS: We conducted an exploratory mixed methods study in 2 public schools in postconflict areas in Tolima, Colombia. This study was conducted in 3 phases. In the adaptation phase, focus groups were conducted with students and teachers to identify changes required in DIALOG+ for it to be used in the school setting. The exploration phase consisted of an exploratory cluster randomized controlled trial. A total of 14 clusters, each with 1 teacher and 5 students, were randomly allocated to either the experimental (DIALOG+S) group or to an active control group (counseling as usual). Teachers in both groups delivered the intervention once a month for 6 months. Through screening scales, information was collected on mental health symptoms, quality of life, self-esteem, resilience, and family functionality before and after the intervention. Finally, the consolidation phase explored the experiences of teachers and students with DIALOG+S using focus group discussions. RESULTS: The changes suggested by participants in the adaptation phase highlighted the central importance of the school setting in the mental health of adolescents. In the exploratory phase, 70 participants with a mean age of 14.69 (SD 2.13) years were included. Changes observed in the screening scale scores of the intervention group suggest that the DIALOG+S intervention has the potential to improve aspects of mental health, especially quality of life, resilience, and emotional symptoms. The consolidation phase showed that stakeholders felt that using this intervention in the school setting was feasible, acceptable, and an enriching experience that generated changes in the perceived mental health and behavior of participants. CONCLUSIONS: Our results are encouraging and show that the DIALOG+S intervention is feasible and acceptable as a promising opportunity to promote well-being and prevent and identify mental health problems in the school context in a postconflict area in Colombia. Larger, fully powered studies are warranted to properly assess the efficacy and potential impact of the intervention and to refine implementation plans.

The impact of COVID-19 pandemic on mental health of adolescents are emerging and require particular attention in settings where challenges like armed conflict, poverty and internal displacement have previously affected their mental wellbeing. This study aimed to determine the prevalence of anxiety symptoms, depressive symptomatology, probable post-traumatic stress disorder and resilience in school-attending adolescents in a post-conflict area of Tolima, Colombia during the COVID-19. A cross-sectional study was carried out with 657 adolescents from 12 to 18 years old, recruited by convenience sampling in 8 public schools in the south of Tolima, Colombia, who completed a self-administered questionnaire. Mental health information was obtained through screening scales for anxiety symptoms (GAD-7), depressive symptomatology (PHQ-8), probable post-traumatic stress disorder (PCL-5) and resilience (CD-RISC-25). The prevalence observed for moderate to severe anxiety symptoms was 18.9% (95% CI 16.0-22.1) and for moderate to severe depressive symptomatology was 30.0% (95% CI 26.5-33.7). A prevalence of probable post-traumatic stress disorder (PTSD) of 22.3% (95% CI 18.1-27.2) was found. The CD-RISC-25 results for resilience had a median score of 54 [IQR 30]. These results suggest that approximately two-thirds of school-attending adolescents in this post-conflict area experienced at least one mental health problem such as anxiety symptoms, depressive symptomatology or probable PTSD during the COVID-19 pandemic. Future studies are of interest to establish the causal relationship between these findings and the impact of the pandemic. These findings highlight the challenge that schools have after pandemic to address the mental health of their students in order to promoting adequate coping strategies and implement prompt multidisciplinary interventions to reduce the burden of mental health problems in adolescents.

A π-conjugated polymer (PBQT) containing bis-(2-ethylhexyloxy)-benzo [1,2-b'] bithiophene (BDT) units alternated with a quinoline-vinylene trimer was obtained by the Stille reaction. The chemical structure of the polymer was verified by nuclear magnetic resonance (1H NMR), Fourier transform infrared (FT-IR), and mass spectroscopy (MALDI-TOF). The intrinsic photophysical properties of the solution were evaluated by absorption and (static and dynamic) fluorescence. The polymer PBQT exhibits photochromism with a change in absorption from blue (449 nm) to burgundy (545 nm) and a change in fluorescence emission from green (513 nm) to orange (605 nm) due to conformational photoisomerization from the trans to the cis isomer, which was supported by theoretical calculations DFT and TD-DFT. This optical response can be used in optical sensors, security elements, or optical switches. Furthermore, the polymer forms spin-coated films with absorption properties that cover the entire visible range, with a maximum near the solar emission maximum. The frontier molecular orbitals, HOMO and LUMO, were calculated by cyclic voltammetry, and values of -5.29 eV and -3.69, respectively, and a bandgap of 1.6 eV were obtained, making this material a semiconductor with a good energetic match. These properties could suggest its use in photovoltaic applications.

Non-alcoholic fatty liver disease (NAFLD) is a spectrum of fat-associated liver conditions that increase risk of cardiovascular disease and mortality. The diagnosis and clinical management of NAFLD remain a challenge for cardiologists. Our group performed a systematic review in PubMed of the relationship between NAFLD and cardiovascular disease, identifying 35 relevant articles. NAFLD is likely to be the liver's expression of metabolic syndrome and increases the risk of several cardiovascular diseases, including coronary artery disease, stroke, heart failure and electrical disorders, and chronic kidney disease. Echocardiography is a useful tool to check early subclinical abnormalities in heart structure and function linked to NAFLD progression, such as cardiac diastolic impairment or epicardial fat thickness. Currently, NAFLD is predominantly managed by lifestyle changes with the aim of weight loss, based on the Mediterranean diet and intense exercise training. Despite the lack of approved drugs for NAFLD, new potential treatments, mainly glucagon-like peptide-1 agonists or sodium-glucose cotransporter 2 inhibitors, could change cardiologists' approach to this pathology.
RESUMEN
Resumen Objetivo: describir un caso de trasplante hepático en un paciente con resultado positivo en la prueba del coronavirus del síndrome respiratorio agudo grave de tipo 2 (SARS-CoV-2) con éxito en el postrasplante temprano, pero que desarrolló complicaciones asociadas a la inmunosupresión y trombosis portal sin una trombofilia identificada en un centro de alta complejidad de un país latinoamericano. Descripción del caso: paciente de 48 años con diagnóstico de cirrosis hepática secundaria a esteatohepatitis no alcohólica (NASH) complicada por varios episodios de ascitis portal hipertensiva y encefalopatía hepática, ingresada para trasplante hepático ortóptico. En los exámenes iniciales tuvo una prueba positiva para SARS-CoV-2 y era asintomático respiratorio. El trasplante se realizó con éxito luego de la autorización del comité de infección. Después del primer mes posoperatorio presentó diarrea, ascitis y daño renal agudo. Los niveles de tacrolimus en el reingreso fueron superiores a 10 ng/mL y hubo una mejoría clínica significativa con la suspensión del fármaco. Finalmente, el paciente requirió retrasplante por trombosis de la vena porta y de las venas suprahepáticas, aunque no se identificó la etiología. Conclusión: se describe uno de los primeros informes de trasplante de hígado en un paciente con recuperación reciente de COVID-19 y pruebas persistentemente positivas. En el postrasplante temprano hubo una buena respuesta; sin embargo, luego del primer mes presentó complicaciones relacionadas con la inmunosupresión. Este caso también plantea la posible asociación entre el SARS-CoV-2 y el desarrollo de trombosis en la circulación portal hepática.
Abstract Objective: To describe a case of liver transplantation in a patient with a positive result in the severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) test with success in the early post-transplantation, but who developed complications associated with immunosuppression and portal vein thrombosis without thrombophilia identified at a tertiary referral center in a Latin American country. Case: A 48-year-old patient diagnosed with liver cirrhosis secondary to non-alcoholic steatohepatitis (NASH) complicated by several episodes of portal hypertension ascites and hepatic encephalopathy was admitted for orthoptic liver transplantation. On initial examinations, he had a positive test for SARS-CoV-2 and was asymptomatic in the respiratory tract. The transplant was carried out successfully after the authorization of the infection committee. After the first postoperative month, he presented with diarrhea, ascites, and acute kidney injury. Tacrolimus levels at readmission were more significant than 10 ng/mL, and there was a significant clinical improvement with drug discontinuation. Finally, the patient required re-transplantation due to thrombosis of the portal vein and suprahepatic veins, although the etiology was not identified. Conclusion: One of the first reports of liver transplantation in a patient with recent recovery from COVID-19 and persistently positive tests is described. In the early post-transplant, there was a good response; however, after the first month, he had complications related to immunosuppression. This case also posits the possible association between SARS-CoV-2 and the development of thrombosis in the hepatic portal circulation.
RESUMEN
A thunderclap headache (TCH) is defined as an excruciating headache which occurs abruptly like "thunder," reaches its maximum point in less than a minute, and should be considered a medical emergency. Below, we present the clinical case of a 49-year-old Colombian patient who developed a thunderclap headache as the initial sign of pituitary apoplexy. He progressed satisfactorily, with no evidence of sequelae, highlighting the early diagnosis of a potentially fatal entity. (Acta Med Colomb 2022; 47. DOI:https://doi.org/10.36104/amc.2022.2336).

RESUMEN
BACKGROUND: Patient and stakeholders' involvement in the development of mental health interventions is a central part of the research process as end-user's input can improve the design of patient-centered interventions. This is particularly important when developing interventions directed towards improving the mental health of children and adolescents. The rising prevalence of mental health disorders in this population requires special attention and the development of interventions that include them as active participants is crucial. OBJECTIVE: Our aim is to explore the perspectives and opinions of adolescents, parents, educators/youth workers, and clinicians regarding the appeal and usability of an existing patient-centered digital intervention (DIALOG+), which aims to improve quality of life. METHODS: As part of a broader study aiming to adapt and test DIALOG+, we conducted Online Focus Groups (OFGs) with adults and adolescents in two cities in Colombia. The existing DIALOG+ intervention was introduced to participants, followed by a structured discussion regarding the opinions and views of stakeholders. A framework approach was used to identify the main themes followed by content analysis to aid adaptation. RESULTS: We conducted 10 OFGs with a total of 45 participants. A positive feature highlighted by all groups was the innovation of including a digital intervention in a traditional medical visit. Additionally, participants considered that the active role that adolescents have when using the intervention empowers them. Barriers identified included concerns from clinicians related to the time required during consultations and confusion with terminology. Furthermore, additional domains that are particularly relevant for the adolescent population were suggested. CONCLUSIONS: Data obtained suggest that overall, the DIALOG+ intervention and supporting app are seen as innovative and appealing to adolescents as well as adult stakeholders. However, concerns raised about the availability of time to apply the intervention, the app interface and the language and terminology require modification.

RESUMEN
Introduction: Understanding community women's relational and financial empowerment in social entrepreneurship could be the key to scaling up community-based human papillomavirus (HPV) self-sampling programs in low- and middle-income countries. The Hope Project, social entrepreneurship in Peru, trains women (Hope Ladies) to promote HPV self-sampling among other women in their communities. This study aims to evaluate the Hope Ladies' relational and financial empowerment after participating in the program. Materials and Methods: We evaluated the Hope Ladies' experiences of empowerment in social entrepreneurship using a parallel convergent mixed methods design. The Hope Ladies participated in semi-structured in-depth interviews (n = 20) and an eight-questions five-point Likert scale survey that evaluated their relational (n = 19)/financial (n = 17) empowerment. The interview and the survey questions were developed using three empowerment frameworks: Kabeer's conceptual framework, International Center for Research on Women's economic empowerment indicators, and the Relational Leadership Theory. Deductive content analysis was used to evaluate the interviews with pre-determined codes and categories of empowerment. Descriptive statistics were used to analyze the survey results. Qualitative and quantitative data were integrated through a cross-case comparison of emergent themes and corresponding survey responses during the results interpretation. Results: All Hope Ladies reported experiencing increased empowerment in social entrepreneurship. Interviews: The women reported challenges and improvement in three categories of empowerment: (1) resources (balancing between household and Hope Lady roles, recognition from the community as a resource, camaraderie with other Hope Ladies); (2) agency (increased knowledge about reproductive health, improved confidence to express themselves, and ability to speak out against male-dominant culture); and (3) achievement (increased economic assets, improved ability to make financial decisions, and widened social network and capital, and technology skills development). Survey: All (100%) agreed/totally agreed an increase in social contacts, increased unaccompanied visits to a healthcare provider (86%), improved confidence in discussing reproductive topics (100%), improved ability to make household decisions about money (57% pre-intervention vs. 92% post-intervention). Conclusions: The Hope Ladies reported improved relational and financial empowerment through participating in community-based social entrepreneurship. Future studies are needed to elucidate the relationship between empowerment and worker retention/performance to inform the scale-up of HPV self-sampling social entrepreneurship programs.

INTRODUCTION: Different organizations have recommended changes in life support in the COVID-19 pandemic, just when maintaining the competence in cardiopulmonary resuscitation is compromised because on-site training must be avoided. We developed a pilot teaching-learning experience to promote cardiopulmonary resuscitation skills acquisition in this situation. The aim of this study was to describe that tool and to analyze its usefulness. METHODS: The experience consisted of three phases: first, reviewing the scientific literature; second, defining written local recommendations and recording a short video simulating the initial attention to a cardiac arrest in this COVID-19 context; third, creating a test to be answered by hospital health professionals. RESULTS: The final sample was 121 subjects; 66.1% were women; the mean age was 45.8 years (SD = 10.24). Among them, 43% were doctors, 43% nurses, 4.1% nursing assistants, and 9.9% others. 89.3% participants had received prior training in life support. In the test, questions 1, 2, 5, 6, 7, and 8 were answered correctly by more than 80%; questions 3 and 4 were answered correctly by 57.9% and 41.3%, respectively. All participants expressed that the video helped them to refresh their knowledge and skills in life support. DISCUSSION: When on-site training is not possible, distance learning-as in our teaching-learning innovation because of the COVID-19 pandemic-may be a valid option to acquire/refresh cardiopulmonary resuscitation skills.

Resumen Introducción: la sepsis se diagnostica en más de 60% de los adultos mayores (AM) en el mundo. Estos AM con frecuencia presentan multimorbilidad y alguno de los síndromes geriátricos, llevando a discapacidad física, cognitiva y psicosocial, lo cual produce altos costos para los sistemas de salud, resultando en un problema grave de salud pública. Objetivo: identificar el impacto de la multimorbilidad y los síndromes geriátricos en la morta lidad de AM hospitalizados por sepsis en una unidad geriátrica de agudos a 30 días de su ingreso. Material y métodos: estudio observacional, analítico de casos y controles anidado en una cohorte. Resultados: se analizaron 238 pacientes con edad media de 83.15±7.12 años, 52.1% fueron mujeres y el 99% tenían al menos una comorbilidad, la mortalidad a 30 días fue 34%. La infección urinaria fue la causa principal de hospitalización (42.9%), obteniendo un aislamiento microbio-lógico en 43.3% de los casos, siendo la Escherichia coli el agente causal más frecuente (46.6%). La regresión logística múltiple mostró que la enfermedad renal crónica (OR 2.1 IC 95% 1.1-4.8; p=0.037), el delirium (OR 3.1 IC 95% 1.6-5.8; p=0.001) y la discapacidad (índice de Barthel <60; OR 3.4 IC 95% 1.5-7.5; p=0.002) se asociaron de manera significativa con la mortalidad a 30 días desde el ingreso a la unidad geriátrica de agudos en paciente con sepsis. Conclusión: en los AM hospitalizados por sepsis, la multimorbilidad, la enfermedad re nal crónica y los síndromes geriátricos representados por delirium y discapacidad fueron los predictores de mortalidad a 30 días.

Abstract Introduction: sepsis is diagnosed in more than 60% of older adults (OAs) worldwide. These OAs often have multimorbidity and one of the geriatric syndromes, leading to physical, cognitive and psychosocial disability with consequently high healthcare costs, resulting in a serious public health problem. Objective: to determine the impact of multimorbidity and geriatric syndromes on the 30-day mortality rate of OAs hospitalized for sepsis in an acute geriatric unit Materials and methods: an observational, analytical, nested case-control study. Results: 238 patients with a mean age of 83.15±7.12 were analyzed; 52.1% were women and 99% had at least one comorbidity; the 30-day mortality was 34%. Urinary tract infection was the main cause of hospitalization (42.9%), with microbiological isolation achieved in 43.3% of cases and Escherichia coli being the most common causal agent (46.6%). Multiple logistic regression showed that chronic kidney disease (OR 2.1 95% CI 1.1-4.8; p=0.037), delirium (OR 3.1 95% CI 1.6-5.8; p=0.001) and disability (Barthel index <60; OR 3.4 95% CI 1.5-7.5; p=0.002) were significantly related to 30-day mortality in patients with sepsis admitted to an acute geriatric unit. Conclusion: in OAs hospitalized for sepsis, multimorbidity, chronic kidney disease and geriatric syndromes (represented by delirium and disability) were the predictors of 30-day mortality.

Su tratamiento continúa constituyendo un reto, dada la persistencia del pobre control, especialmente en países como Colombia. Objetivo: Mostrar la evidencia disponible respecto al tratamiento actualizado de la HTA y la elección certera de los agentes antihipertensivos acorde con la individualidad de cada paciente. Asimismo, consolidar y comparar el efecto hipotensor de cada agente antihipertensivo más usado. Metodología: Se realizó una búsqueda avanzada con los términos DeCS y MeSH: hipertensión, agentes antihipertensivos, hipertensión esencial y terapia combinada, en los motores de búsqueda PubMed, Clinical Key, Lilacs, Scielo. Un total de 109 artículos se seleccionaron para elaborar en la presente revisión de la literatura. Conclusiones: La individualización del manejo de la HTA lleva al reconocimiento de los distintos fenotipos, la presencia de complicaciones, el examen físico, el género y la raza como puntos fundamentales para elegir el agente antihipertensivo más adecuado que permita alcanzar las metas de control y propenda por la reducción y prevención de las complicaciones derivadas de un control no óptimo.
Abstract Introduction: Systemic arterial hypertension (HT) constitutes the main risk factor for cardiovascular morbidity and mortality at a global level, affecting all ages regardless of gender and ethnicity. Its treatment continues to be a challenge, given the persistence of poor control, especially in countries like Colombia. Objective: To show the available evidence regarding the updated treatments of HT and the correct choice of antihypertensive agents according to the individual needs of each patient. Likewise, to consolidate and compare the hypotensive effect of the most used antihypertensive agents. Methodology: An advanced search was carried out with the terms DeCS and MeSH: Hypertension, antihypertensive agents, Essential Hypertension and Combination Therapy through the search engines PubMed, Clinical Key, Lilacs, Scielo. A total of 109 articles were selected to prepare the present literature review. Conclusions: An individualized hypertension treatment plan leads to the recognition of the different phenotypes, the presence of complications, the gender, and race, which are fundamental aspects to consider when choosing the appropriate antihypertensive agents. These findings allow for the achievement of the desired blood pressure target and leads to reduction and prevention of complications derived from suboptimal control.

BACKGROUND: Although focus groups are a valuable qualitative research tool, face-to-face meetings may be difficult to arrange and time consuming. This challenge has been further compounded by the global COVID-19 pandemic and the subsequent lockdown and physical distancing measures implemented, which caused exceptional challenges to human activities. Online focus groups (OFGs) are an example of an alternative strategy and require further study. At present, OFGs have mostly been studied and used in high-income countries, with little information relating to their implementation in low- and middle-income countries (LMICs). OBJECTIVE: The aim of this study is to share our experiences of conducting OFGs through a web conferencing service and provide recommendations for future research. METHODS: As part of a broader study, OFGs were developed with adults and adolescents in Colombia during the COVID-19 pandemic. Through a convenience sampling method, we invited eligible participants via email in two different cities of Colombia to participate in OFGs conducted via Microsoft Teams. Researcher notes and discussion were used to capture participant and facilitator experiences, as well as practical considerations. RESULTS: Technical issues were encountered, but various measures were taken to minimize them, such as using a web conferencing service that was familiar to participants, sending written instructions, and performing a trial meeting prior to the OFG. Adolescent participants, unlike their adult counterparts, were fluent in using web conferencing platforms and did not encounter technical challenges. CONCLUSIONS: OFGs have great potential in research settings, especially during the current and any future public health emergencies. It is important to keep in mind that even with the advantages that they offer, technical issues (ie, internet speed and access to technology) are major obstacles in LMICs. Further research is required and should carefully consider the appropriateness of OFGs in different settings.
RESUMEN
Resumen La coagulación intravascular diseminada es un proceso sistémico caracterizado por la activación generalizada de la coagulación, que tiene el potencial de causar trombosis vascular, hemorragia y falla orgánica. En raras ocasiones, las anomalías vasculares, como el aneurisma aórtico abdominal, pueden desencadenar coagulación intravascular diseminada crónica. Los aneurismas aórticos grandes, su disección y su expansión son factores de riesgo. En estos casos predominan los síntomas subclínicos y la coagulopatía solo se identifica mediante pruebas de laboratorio. Existe evidencia limitada basada en la experiencia de series de casos de coagulación intravascular diseminada crónica como complicación en pacientes con aneurisma aórtico abdominal. Además, la duración y la respuesta terapéutica a la heparina no se conocen bien, principalmente en los pacientes con manejo conservador. Se considera un desafío diagnóstico y terapéutico debido a la baja frecuencia de presentación. A continuación, se describen las características clínicas y paraclínicas, así como el tratamiento, de un paciente con aneurisma aórtico abdominal asociado con coagulación intravascular diseminada crónica.
Abstract Disseminated intravascular coagulation is a systemic process characterized by the widespread activation of coagulation with the potential for causing vascular thrombosis, hemorrhage and organ failure. Rarely, vascular anomalies like abdominal aortic aneurysm can trigger chronic disseminated intravascular coagulation. Large aortic aneurysms, dissection and expansion are risk factors. In these cases, subclinical symptoms predominate and coagulopathy is only identified by laboratory tests. Nowadays there is limited evidence based on experience from case series of chronic disseminated intravascular coagulation as complication in patients with abdominal aortic aneurysm. Furthermore, duration and therapeutic response with heparin therapy are not well known, mainly in those patients with conservative management. It is considered a diagnostic and therapeutic challenge due to the low presentation frequency. The clinical characteristics, laboratory and treatment of a patient with abdominal aortic aneurysm associated with chronic disseminated intravascular coagulation are described below.

Materiales y métodos: Estudio analítico, experimental, longitudinal y prospectivo. Los frutos cerezo y tumbo se recolectaron en las regiones de Cusco, Moquegua y Arequipa. La técnica de Folin-Ciocalteu fue empleada para determinar el contenido de fenoles, y el cloruro de aluminio se utilizó para calcular los flavonoides. La actividad antioxidante se evaluó mediante las técnicas Ferric Reducing Ability of Plasma (FRAP), 2,2-difenil-picril-hidrazil (DPPH) y sustancias reactivas al ácido tiobarbitúrico (TBARS). Para estudiar el efecto hepatoprotector de las frutas, utilizamos ratas albinas que se clasificaron en un grupo control negativo, un grupo control positivo y cuatro grupos experimentales. Resultados: La mayor concentración de fenoles totales y flavonoides se encontró en el tumbo de la región Cusco (Quechua) (fenoles totales: 584,94 ± 134,62 mg EAG / 100 g y flavonoides :445,62 ± 7,94 mg EQ / 100 g). Para el radical DPPH, el valor IC50 del tumbo de la región Arequipa (Yunga) fue 0,41 ± 0,01 mg / mL. El tumbo de la región Cusco (Quechua) mostró el valor FRAP más alto (8,38 ± 0,32 mmol Fe2 + / 100 g). El cerezo de la región de Arequipa (Yunga) presentó la mayor concentración de fenoles totales (181,81 ± 34,1 mg EAG / 100 g) y flavonoides (205,18 ± 77,8 mg EQ / 100 g). El cerezo de Arequipa (Yunga) mostró una actividad antioxidante significativa al DPPH (2,1 ± 0,01 mg / mL), mientras que la capacidad antioxidante del cerezo de la región Cusco (Quechua), evaluada con la técnica FRAP, alcanzó un valor de 1,59 ± 0,2 mmol Fe2+/100 g. Las diferencias observadas fueron estadísticamente significativas. El tumbo mostró un mejor efecto hepatoprotector que el cerezo. Conclusiones: El tumbo de la región Cusco (Quechua) es una fuente importante de compuestos antioxidantes y muestra una elevada capacidad antioxidante (FRAP), mientras que el cerezo de la región Arequipa (Yunga) tiene un alto contenido de compuestos antioxidantes y una mayor capacidad antioxidante (DPPH).
Objective: To determine the content of bioactive compounds and antioxidant capacity of the banana passionfruit (Passiflora mollissima) and black cherry (Prunus serotina). Materials and methods: An analytical, experimental, longitudinal and prospective study. The black cherries and banana passionfruits were collected in the Cusco, Moquegua and Arequipa regions. The content of phenols and flavonoids were determined using the Folin-Ciocalteu reagent and aluminum chloride method, respectively. The antioxidant activity was evaluated using the ferric reducing ability of plasma (FRAP), 2,2-diphenyl-1-picryl-hydrazyl (DPPH) and thiobarbituric acid reactive substance (TBARS) techniques. Albino rats classified into a negative control group, a positive control group and four experimental groups were used to study the hepatoprotective effect of the fruits. Results: Banana passionfruits from the Cusco region (Quechua) showed the highest concentration of total phenols (584.94 ± 134.62 mg GAE/100 g) and flavonoids (445.62 ± 7.94 mg QE/100 g). Concerning the DPPH radical, the IC 50 value of banana passionfruits from the Arequipa region (Yunga) was found to be 0.41 ± 0.01 mg/mL. Banana passionfruits from the Cusco region (Quechua) showed the highest FRAP value (8.38 ± 0.32 mmol Fe2+/100 g). Black cherries from the Arequipa region (Yunga) had the highest concentration of total phenols (181.81 ± 34.1 mg GAE/100 g) and flavonoids (205.18 ± 77.8 mg QE/100 g). They also showed a significant antioxidant activity regarding the DPPH (2.1 ± 0.01 mg/mL), while the antioxidant capacity of black cherries from the Cusco region (Quechua), which was evaluated with the FRAP method, achieved a value of 1.59 ± 0.2 mmol Fe2+/100 g. The observed differences were statistically significant. Banana passionfruits showed a better hepatoprotective effect than black cherries. Conclusions: Banana passionfruits from the Cusco region (Quechua) are an important source of antioxidant compounds and show a high antioxidant capacity (FRAP), while black cherries from the Arequipa region (Yunga) have a high content of antioxidant compounds and a higher antioxidant capacity (DPPH).
RESUMEN
Abstract This case series describes the clinical and paraclinical findings in two young men with bilateral peripheral facial palsy or facial diplegia during the convalescent period of leptospirosis, who recovered neurologically without sequelae. This highlights the role of spirochetes in the development of an atypical and rare variant of Guillain-Barré syndrome. (Acta Med Colomb 2021; 46. DOI:https://doi.org/10.36104/amc.2021.1947).
