ABSTRACT
Ethnobotany approached through ethnoeducation allows for the preservation of the cultural heritage of indigenous communities. In this way, the ethnobotanical knowledge of primary school students from the Paniquita Indigenous Community was recognized, regarding the cultural knowledge of medicinal plants and their significance in the conservation of the biocultural heritage. This research had a qualitative, ethnographic approach. The sample consisted of ten students who were part of a focus group, ethnobotanical walks, and participatory workshops with drawings since they stimulate students' creative and dynamic thinking and strengthen interculturality. Twenty-one plants were reported, which are used to relieve sore throats, headaches, and stomach aches, as well as to treat diarrhea and fever, to prevent flu, and as a purgative. All the medicinal plants mentioned grow in the community and are either cultivated or wild, which also shows the students' knowledge of the ir territory. These findings reflect the importance of ethno-education and ethnobotany at school and how historical reconstruction processes are generated from these settings, where indigenous ancestral knowledge is made visible.
La etnobotánica abordada desde la etnoeducación permite mantener el legado cultural de los pueblos originarios. De esta manera, se reconoció el conocimiento etnobotáni co de los estudiantes de primaria de la Comunidad Indígena Paniquita, sobre el conocimiento cultural de las plantas medicinales y su importancia para la conservación del patrimonio biocultural. La investigación tuvo un enfoque cualitativo y etnográfico. La muestra estuvo conformada por diez estudiantes que formaron parte de un grupo focal, caminatas etnobotánicas y talleres participativos con dibujos, ya que estimulan el pensamiento creativo y dinámico de los estudiantes y fortalecen la interculturalidad. Se reportaron 21 plantas que se utilizan para aliviar dolores de garganta, cabeza y estómago, así como para tratar la diarrea y la fiebre, para prevenir la gripe y como purgante. Todas las plantas medicinales mencionadas crecen en la comunidad y son cultivadas o silvestres, lo que también demuestra el conocimiento que los estudiantes tienen de su territorio. Estos hallazgos reflejan la importancia de la etnoeducación y la etnobotánica en la escuela y cómo se generan procesos de reconstrucción histórica desde estos escenarios, donde se visibiliza el conocimiento ancestral indígena.

This review presents advances in the implementation of high - throughput se quencing and its application to the knowledge of medicinal plants. We conducted a bibliographic search of papers published in PubMed, Science Direct, Google Scholar, Scopus, and Web of Science databases and analyzed the obtained data using VOSviewer (versi on 1.6.19). Given that medicinal plants are a source of specialized metabolites with immense therapeutic values and important pharmacological properties, plant researchers around the world have turned their attention toward them and have begun to examine t hem widely. Recent advances in sequencing technologies have reduced cost and time demands and accelerated medicinal plant research. Such research leverages full genome sequencing, as well as RNA (ribonucleic acid) sequencing and the analysis of the transcr iptome, to identify molecular markers of species and functional genes that control key biological traits, as well as to understand the biosynthetic pathways of bioactive metabolites and regulatory mechanisms of environmental responses. As such, the omics ( e.g., transcriptomics, metabolomics, proteomics, and genomics, among others) have been widely applied within the study of medicinal plants, although their usage in Colombia is still few and, in some areas, scarce.

Introduction: Glaucoma is a leading cause of irreversible blindness. It is a prevalent disease worldwide, affecting â¼70 million people and expected to reach up to 112 million by 2040. Purpose: The aim of this study is to describe the implementation and initial experience of a telemedicine program to monitor glaucoma and glaucoma suspect patients in a large, integrated health care system during the COVID-19 pandemic. Methods: A retrospective chart review of established glaucoma or glaucoma suspect patients who participated in a telemedicine evaluation at the ophthalmic center of a large, Colombian health care system between June 2020 and April 2023 was conducted. Clinical and sociodemographic variables were analyzed. Generated clinical orders for additional testing, surgical procedures, follow-ups, and referrals, as well as changes in medical treatment, were evaluated. Results: A total of 11,034 telemedicine consults were included. The mean ± standard deviation age of this group was 63 ± 17.2 years and 67% were female. Of the patients who attended teleconsults, 49% were glaucoma suspects and 38.5% were followed with a diagnosis of open-angle glaucoma. After the consult, 25% of patients were referred to a glaucoma specialist, 40% had additional testing ordered, and 8% had a surgical procedure ordered, mainly laser iridotomy (409 cases). Almost a third of patients returned for subsequent telemedicine visits after the initial encounter. Despite some technical difficulties, 99.8% of patients attended and completed their scheduled telemedicine appointments. Conclusions: A telemedicine program aimed to monitor established glaucoma patients can be successfully implemented. Established patients within an integrated health care system have high adherence to the virtual model. Further research by health care institutions and government agencies will be key to expand coverage to additional populations. Clinical Trial Registration Number: CEIFUS 1026-24.

Propolis extracts have been widely studied due to their popularity in traditional medicine, presenting incredible biodiversity. This study aimed to analyze propolis extracts' phytochemical, physicochemical, and biological activities from four different biogeographic zones of the Huila region (Colombia). The raw material samples were collected by the scraping method and the ethanolic extracts (EEPs) were obtained by cold maceration with ethanol (96%). The physicochemical and sensory characterization was carried out according to the protocols recommended by the Brazilian Ministry of Agriculture and the main components of the EEPs were identified by LC-HRMS analysis. The determination of total phenols and flavonoids was carried out using colorimetric techniques. The antioxidant activity, cytotoxicity, and cell cycle regulation analyses in L929 and HGnF cells were evaluated using DPPH, Alamar Blue, and 7-amino actinomycin D (7-AAD) assays. The propolis samples presented an average yield of 33.1%, humidity between 1.6 and 2.8%, melting point between 54 and 62 °C, ashes between 1.40 and 2.19%, and waxes of 6.6-17.9%, respectively. The sensory characteristics of all samples were heterogeneous, complying with the quality specifications established by international standards. The polyphenolic and total flavonoid content was representative in the samples from Quebradon (255.9 ± 9.2 mg GAE/g, 543.1 ± 8.4 mg QE/g) and Arcadia (543.1 ± 8.4 mg GAE/g, 32.5 ± 1.18 g QE/g) (p < 0.05) that correlated with high antioxidant activity (Quebradon: 37.2 ± 1.2 µmol/g, Arcadia: 38.19 ± 0.7 µmol/g). In the chemical composition analysis, 19 compounds were characterized as phenolic acids and flavonoids, the most representative being chrysoeriol-O-methyl-ether, ellagic acid, and 3,4-O-dimethylcaffeic acid. Regarding biological activity, Quebradon and Arcadia propolis presented low toxicity with IC50 of 2.83 ± 2.3 mg/mL and 4.28 ± 1.4 mg/mL in HGnF cells, respectively, and an arrest of the cell cycle in the G2/M phase of 71.6% and 50.8% compared to the control (11.9%) (p < 0.05). In general, the results of this study contribute to the identification of valid quality criteria to evaluate Colombian propolis, contributing to its study and chemical and biological characterization as a source of raw material for industrial and pharmaceutical use. In addition, Quebradon and Arcadia propolis can be important sources of bioactive molecules for the development of new drugs.

INTRODUCTION: Recent evidence indicates that Maternal Supplementation with Long-Chain n-3 Fatty Acids During Pregnancy Substantially Mitigates Offspring's Asthma. Adding information regarding its cost-utility will undoubtedly allow its adoption, or not, in clinical practice guidelines. This research aimed to determine the cost-utility of LCPUFA supplementation in the third trimester of pregnancy to reduce the risk of wheezing and asthma in infants in Colombia. METHODS: A Markov model was formulated to estimate the cost and quality-adjusted life-years (QALYs) attributed to individuals with severe asthma in Colombia, with a time horizon of five years and a cycle length of two weeks. Probabilistic sensitivity analysis and a value of information (VOI) analysis were conducted to evaluate the uncertainties in the case base. Cost-utility was assessed at a willingness-to-pay (WTP) value of US$5180. All costs were adjusted to 2021 with a 5% annual discounting rate for cost and QALYs. RESULTS: The mean incremental cost of LCPUFA supplementation versus no supplementation was US-43.65. The mean incremental benefit of LCPUFA supplementation versus no supplementation was 0.074 QALY. The incremental cost-utility ratio was estimated at US$590.68 per QALY. The outcomes derived from our primary analysis remained robust when subjected to variations in all underlying assumptions and parameter values. CONCLUSION: Supplementation strategy supplementation with long-chain n-3 fatty acids during pregnancy is cost-effective in reducing the risk of developing asthma during childhood in Colombia.

The aim was to understand the way of life and self-care practices in mental health among adult male farmers living in a municipality in the Risaralda department, located in the coffee axis of Colombia, marked by a high incidence of suicides. An ethnographic study was conducted between March and December 2021, employing a combination of methods including interviews, participant observation, document review, and field diaries. Economic and social aspects undergoing transformations were identified, impacting gender roles, family dynamics, and caregiving possibilities for these men. By observing how men discuss their suffering and the resources available to address it, it can be concluded that mental health practices function more as self-care resources, while health services often provide symptom-based care, neglecting attentive listening. These findings are valuable for shaping services and life care strategies that align with the conditions of rural men in Colombia.
El objetivo fue conocer el modo de vida y las prácticas de autocuidado en salud mental de los hombres adultos campesinos, que viven en un municipio del departamento de Risaralda en el eje cafetero de Colombia con alta incidencia de suicidios. Entre marzo y diciembre de 2021, se realizó un estudio etnográfico, haciendo uso de una combinación de métodos: entrevistas, observación participante, revisión documental y diario de campo. Se identificaron aspectos económicos y sociales cuyas transformaciones han afectado los roles de género, las dinámicas familiares y las posibilidades de cuidado para los hombres. Al observar cómo los hombres hablan de su sufrimiento y de los recursos con que cuentan para atenderlo, puede concluirse que las prácticas de salud mental se encuentran más bien como recursos de autoatención y los servicios de salud ofrecen atención basada en síntomas del cuerpo, de modo que abandonan la escucha. Estos hallazgos son útiles para pensar servicios y estrategias de cuidado de la vida que se adapten a las condiciones de hombres campesinos en Colombia.

BACKGROUND: Mycosis fungoides is the most frequent form of cutaneous T-cell lymphoma. It is characterized by a chronic, slow, and progressive course, and is associated with mortality rates that depend on several factors, such as clinical staging. A median survival time of up to 13 months is found in patients with advanced stages that require more aggressive treatments, with greater toxicity and higher costs. In Latin America, few prognostic studies of the disease are available. OBJECTIVE: To determine the rate of progression from early stages (IA, IB, IIA) to more advanced stages (> IIB) in patients older than 18 years with mycosis fungoides treated at two medical centers in Colombia between January 1, 2010, and December 31, 2019. METHODS: Retrospective cohort study with a longitudinal design. RESULTS: 112 patients diagnosed with early mycosis fungoides were included. 56.2% were male (n = 63), with a median age of 53 years (IQR 43â67). The most frequent clinical variant was classic (67.9%; n = 76), followed by folliculotropic (16%; n = 18), and hypopigmented (10.7%; n = 12). The most common first-line treatment was NB-UVB phototherapy (27.7%; n = 31), followed by PUVA phototherapy (25.8%; n = 29%), and topical corticosteroids (25%; n = 28). The global rate of disease progression was 8% (n = 9), with an overall mortality of 12.5% (n = 14). STUDY LIMITATIONS: Its retrospective design and the lack of molecular studies for case characterization. CONCLUSIONS: Early mycosis fungoides is a disease with a good prognosis in most patients, with a progression rate of 8% (n = 9).

This work reports on the extraction and characterization of the behavior of starch from residues of several potato varieties (Criolla, Sabanera and Pastusa) of Colombian origin from the Andean region using different techniques and the evaluation of the effect of citric acid (CA) on the grain morphology. Additionally, films were produced with each one of the extracted starches and glycerol. Pastusa variety starch shows a higher granule size than the other varieties and Pastusa starch shows lower amylose content compared to Sabanera and Criolla. Criolla and Pastusa starches exhibit more thermal stability than Sabanera starch. Starch-glycerol films were also produced using the cast solving method. The films were mechanically analyzed by tensile test and the barrier properties were assessed by water vapor permeability (WVP). The tensile strength of the films varied in the 2.0-2.4 MPa range, while the elongation at break was comprised between 25 and 32 %. With regard to water vapor permeability, the obtained values fall within the 4-7 × 10-10 g m-1 s-1 Pa-1 range. It was observed that the thickness of the films and the protein content affected water vapor permeability, increasing this value at higher levels of thickness.

Length-weight relationships (LWR) and relative condition factor were described for species of deep-water crustaceans caught with bottom trawls in a depth range between 150 and 535 m during August and December of 2009, and March and May of 2010 in the Colombian Caribbean Sea. A linear regression was performed using the logarithmically transformed data to calculate the a and b coefficients of the LWR for 22 crustacean species corresponding to 13 families and 19 genera and three types of crustaceans (shrimp, crab, lobster). Six crustacean species showed a maximum total length greater than that reported in SeaLifeBase: Garymunida longipes (77.00 mm), Eunephrops bairdii (220.00 mm), Metanephrops binghami (197.46 mm), Penaeopsis serrata (149.00 mm), Polycheles typhlops (196.27 mm) and Pleoticus robustus (240.00 mm). A total of 11 species (50.0%) exhibited isometric growth, five species (22.7%) negative allometric and six species (27.3%) positive allometric. This study shows the first estimates of LWR for 12 species of deep-water crustaceans in the Colombian Caribbean Sea. We demonstrate for the first time that the growth parameters (intercept and slope) of the LWR varying significantly as a function of the body shape of crabs, lobsters and shrimps in deep-water crustaceans.

While the importance of interdisciplinary approaches is increasingly recognised in conservation, bridging knowledge systems across scales remains a fundamental challenge. Focusing on the Important Plant Areas (IPA) approach, we evaluate how complementing scientific and local knowledge can better inform the conservation of useful plants in Colombia. We worked in three municipalities to investigate knowledge on useful plant richness, species composition and use types, as well as perceptions on area-based plant conservation approaches. Participatory focus groups and ethnobotanical walks-in-the-woods were undertaken with local communities, while scientific data were represented by occurrence records from global data aggregators and digitised collections. A total of 1190 species with human uses were reported. Combining knowledge systems provided the richest understanding of useful plants but the relative contribution of each system varied between study areas, influenced by the history of scientific studies, socio-ecological context and study design. Meanwhile, local perceptions of how conservation areas should be selected differed from global IPA criteria. These results show that working with local communities can improve biological understanding for spatial conservation planning. Additionally, participatory approaches must move beyond community-based conservation and data collection, to inform the design of global conservation programmes.
RESUMEN: Si bien la importancia de los enfoques interdisciplinarios se reconoce cada vez más en la conservación, articular los sistemas de conocimiento a través de sus escalas sigue siendo un desafío fundamental. Centrándonos en el enfoque de Áreas Importantes para Plantas (AIP), evaluamos cómo la integración entre conocimiento científico y local puede mejorar la información para la conservación de las plantas útiles en Colombia. Trabajamos en tres municipios para investigar el conocimiento sobre la riqueza de plantas útiles, la composición de especies y los tipos de uso, así como las percepciones sobre los enfoques de conservación de plantas basados en áreas. Se llevaron a cabo grupos de enfoque participativos y caminatas etnobotánicas en el bosque con las comunidades, mientras que los datos científicos se representaron mediante registros de ocurrencia de agregadores de datos globales y colecciones digitalizadas. En total se reportaron 1.190 especies con usos humanos. La combinación de sistemas de conocimiento proporcionó la comprensión más rica de las plantas útiles, pero la contribución relativa de cada sistema varió entre las áreas de estudio, influenciada por la historia de los estudios científicos, el contexto socioecológico y el diseño del estudio. Por otra parte, las percepciones locales sobre cómo se deben seleccionar las áreas de conservación difirieron de los criterios globales de las AIP. Estos resultados muestran que trabajar con las comunidades locales puede mejorar la comprensión biológica para la planificación de la conservación espacial. Además, los enfoques participativos deben ir más allá de la recopilación de datos y la conservación basada en la comunidad, para instruir el diseño de programas de conservación global.

INTRODUCTION: Diet-based interventions may be a culturally acceptable option to decrease mercury levels and thus prevent the adverse effects of this metal on population health. Selenium is an element present in Colombian geology that can act as a chelator, decreasing mercury concentrations in the human body. OBJECTIVE: To identify potentially useful selenium-rich foods to control the effects of mercury exposure among Afro-Colombians. MATERIALS AND METHODS: A cross-sectional study was carried out with 320 individuals from five municipalities of Chocó. They were asked about the frequency of consumption of selenium-rich foods, and their association with mercury concentrations in hair was estimated with multiple robust regression. RESULTS: Guava, whole wheat flour, strawberries, cow liver, spinach and yeast extract were the foods with higher consumption. Walnuts, whole wheat flour, and yeast extract were identified in multiple robust regression as foods to consider in future interventions. CONCLUSION: It is proposed that the banana juice, the pineapple colada, the borojó (Borojoa patinoi) sorbet, the cucas, and the enyucado are basic elements for a culturally acceptable intervention.
Introducción: Las intervenciones basadas en la dieta pueden ser una opción culturalmente aceptable para disminuir los niveles de mercurio y prevenir los efectos adversos de este metal en la salud de la población. El selenio es un elemento presente en la geología colombiana que puede actuar como quelante, disminuyendo las concentraciones de mercurio en el cuerpo humano. Objetivo: Identificar los alimentos ricos en selenio potencialmente útiles para controlar los efectos de la exposición a mercurio entre afrocolombianos. Materiales y métodos: Se realizó un estudio transversal con 320 individuos de cinco municipios del departamento del Chocó. Se les preguntó sobre la frecuencia de consumo de alimentos ricos en selenio y su asociación con las concentraciones de mercurio en cabello fue estimada con regresión múltiple robusta. Resultados: La guayaba, la harina de trigo integral, las fresas, el hígado de vaca, la espinaca y el extracto de levadura fueron los alimentos de mayor consumo. Las nueces, la harina de trigo integral y el extracto de levadura fueron identificados en regresión múltiple robusta como alimentos por considerar en futuras intervenciones. Conclusiones: Se propone que el jugo de plátano, la piña colada, el sorbete de borojó (Borojoa patinoi), las cucas, el enyucado y la sábida de plátano primitivo maduro son elementos básicos para una intervención culturalmente aceptable.

Intestinal parasites continue to be a public health problem in low- and middle-income countries. Broad use of anthelmintics during deworming programs is still necessary in many regions. However, description of the usage of these medications in general medical practice has been limited. The objective of this study was to determine the use of anthelmintic drugs and their indications in a group of Colombian patients. This was a descriptive study from a drug-dispensing database, identifying patients with prescriptions for anthelmintic drugs. A total of 381 cases were randomly selected, and their medical records were reviewed, analyzing sociodemographic, clinical, and pharmacological variables (indication of use). The lack of diagnosis registration or clinical manifestations of parasites was determined as a prescription without indication. In total, 50.9% (n = 194) of patients were female, and 67.4% of all patients were under 18 yr of age. The diagnosis of helminthiases was clearly stated in 114 (29.9%) patients, and only 4.2% (n = 16) of these had microbiological confirmation. The most commonly used anthelmintic drug was albendazole (70.4% of all prescriptions). The use of anthelmintics was not indicated in 266 cases (69.8%). Nutritional supplements or vitamin prescriptions were associated with using anthelmintics without indication (odds ratio: 2.25; 95% confidence interval: 1.26-4.03). A high proportion of patients lacked symptoms or diagnoses in their clinical records that supported the use of anthelmintic drugs.

Coffee is one of the most important agricultural products in Colombia. To date, small-scale Colombian coffee growers have developed this activity with a simple infrastructure and random use of water that generates harmful by-products to the water resource mainly in the stage of separation of the mucilage. The coffee mucilage wastewater (CMW) is composed of high organic loads and its impact on water sources is due to its high load of nutrients such as nitrogen (N), phosphorus (P), and chemical oxygen demand (COD) values of over 25,000 mg/L. However, there is no consensus on what treatment can be used, especially whether it is accessible to coffee producers. Thus , the aim of this study consisted of assessing the performance of the combination of a carbon filter (CF) as pretreatment and vertical flow wetland (VFW) as a Natural-based Solution (NbS). The results show a reduction of more than 85% of COD, 96% of total solids, and UV254 close to 94%. It was remarkable that both treatments are appropriate for waters with a high concentration of solids. Finally, it can be concluded that CF + VFW is a feasible technology to treat the coffee wastewater from small communities of coffee producers.

BACKGROUND: The use of complementary and alternative medicines (CAM) among cancer patients varies greatly. The available data suggest an increasing use of CAM over time and a higher prevalence in low- and middle-income countries. However, no reliable data are available from Latin America. Accordingly, we examined the prevalence of CAM use among cancer patients from six Colombian regions. METHODS: We conducted a survey on cancer patients attending comprehensive cancer centres in six capital cities from different regions. The survey was designed based on a literature review and information gathered through focus groups on CAM terminology in Colombia. Independent random samples of patients from two comprehensive cancer centres in every city were obtained. Patients 18 years and older with a histopathological diagnosis of cancer undergoing active treatment were eligible. The prevalence of CAM use is reported as a percentage with the corresponding confidence interval. CAM types are reported by region. The sociodemographic and clinical characteristics of CAM users and non-users were compared using Chi square and t tests. RESULTS: In total, 3117 patients were recruited. The average age 59.6 years old, and 62.8% were female. The prevalence of CAM use was 51.7%, and compared to non-users, CAM users were younger, more frequently women, affiliated with the health insurance plan for low-income populations and non-Catholic. We found no differences regarding the clinical stage or treatment modality, but CAM users reported more treatment-related side effects. The most frequent types of CAM were herbal products, specific foods and vitamins, and individually, soursop was the most frequently used product. Relevant variability between regions was observed regarding the prevalence and type of CAM used (range: 36.6% to 66.7%). The most frequent reason for using CAM was symptom management (30.5%), followed by curative purposes (19.5%). CONCLUSIONS: The prevalence of CAM use among cancer patients in Colombia is high in general, and variations between regions might be related to differences in cultural backgrounds and access to comprehensive cancer care. The most frequently used CAM products and practices have little scientific support, suggesting the need to enhance integrative oncology research in the country.

Cancer survival has significantly increased during the past few decades, making survivorship care a key element of cancer control and posing several challenges for long-term care in low- and middle-income countries (LMIC). Most survivorship care guidelines emphasize the potential role of primary care physicians and the need for comprehensive care, with a preference for patient-centered over disease-centered approaches. However, guidelines developed in high-income countries are not always suitable for LMIC, where a shortage of oncology workforce, deficient training in primary care, and low access to comprehensive centers frequently induce undertreatment and a lack of follow-up. Despite universal health insurance coverage, Colombia has fragmented cancer care with deficient survivorship care, given its focus on relapse surveillance without integration of supportive care and comorbidity management, in addition to unequal access for low-income populations and distant regions. Using the breast cancer framework, we describe the development of a guideline for survivorship care on the basis of a risk approach and the proper integration of oncology specialists and family physicians. We used a three-phase process to develop recommendations for disease control (disease-centered review), interventions aimed at improving patients' quality of life (patient-centered review), and care delivery (delivery model review). We deem our proposal suitable for middle-income countries, which represents an input for more standardized survivorship care in these settings.

PURPOSE: To determine the effect of an online Workplace Vocal Health and Low Stress Levels (WVHLS) Promotion Program implemented in a Colombian university during COVID-19 pandemic. METHODS: This research was a quasi-experimental study. Twenty-nine professors participated in this study within two groups: (1) intervention group (n=17) or (2) non-intervention group (n=12). Participants in the intervention group took part in four virtual sessions about how to improve vocal health and strategies to reduce stress levels during their homeworking and online classes. Teachers filled in a questionnaire including questions about working conditions, work-related stress, and the voice functioning (including the Vocal Fatigue Index-VFI). They also recorded a voice sample of a sustained vowel on two separate occasions (before and after the follow-up). RESULTS: At the end of the follow-up, there was a tendency to reduce Factor 1 of VFI in the intervention group. Although, all participants had a longer MPT at the end of the study compared with the baseline measures, males in the intervention group had longer MPT compared with other participants. CONCLUSION: Our results suggest a positive effect of a WVHLS promotion program on reducing vocal fatigue perception measured by means of the Vocal Fatigue Index and improving coordination and control of breathing speech measured MPT. These changes at the end of the follow-up may indicate that holistic programs that include voice care recommendations, breathing exercises, vocal warm-up, cold-down and laryngeal relaxation vocal exercises, and stress management may be beneficial for reducing work-related stress and voice symptoms among professors.

BACKGROUND: Sarcopenia is a condition associated with aging and multiple medical conditions such as CKD and hypovitaminosis D. METHODS: An observational cross-sectional study was carried out, based on patients registered in a database of specialized nephrology consultation in the city of Manizales, Colombia. 101 patients over 18 years of age who had stage 3 or 4 CKD were included. RESULTS: The frequency of sarcopenia was 10.9%. No relationship was found between sarcopenia alone and serum vitamin D levels. However, when sarcopenia was categorized as severe there was a direct relationship with hypovitaminosis D. There was also a direct relationship between dynapenia and hypovitaminosis D. In addition, patients who had serum vitamin D levels above 40 ng/ml had better muscle performance, and, consequently, probably a lower risk of frailty. CONCLUSION: When patients, within their treatment, received vitamin D supplementation, no effect on muscle performance was observed.

The insertion of circular economy principles into the essential oil (EO) production chain aims to reduce waste generation and make integral use of harvested plant material. Higher profits from integral use with reduced waste generation contribute to the eventual use of the EO value chain as an alternative to illicit crops in Colombia (mostly coca). In this study, Java-type citronella (Cymbopogon winterianus) and palmarosa (C. martinii) plant materials were used in two consecutive processes to obtain EOs and extracts. The residual biomass after EO distillation was subjected to ultrasound-assisted hydroethanolic extraction to afford extracts that contained bioactive compounds. Citronella and palmarosa were distilled with typical EO yields (1.0 ± 0.1% for citronella; 0.41 ± 0.06% for palmarosa; n = 5) either through hydrodistillation assisted by microwave radiation or through steam distillation, and their composition (determined via GC/FID/MS analysis) and physicochemical parameters fell within their ISO standard specifications. The concentration of citronellal, the major compound of citronella oil, was 500 ± 152 mg/g. Geraniol, the main component of palmarosa oil, was found at 900 ± 55 mg/g. The citronella and palmarosa hydroalcoholic extracts (4-11% yield) were analyzed with UHPLC-ESI-Orbitrap-MS, which permitted the identification of 30 compounds, mainly C-glycosylated flavones and hydroxycinnamic acids. Both extracts had similar antioxidant activity values, evaluated using the ABTS+â and ORAC assays (110 ± 44 µmol Trolox®/g extract and 1300 ± 141 µmol Trolox®/g extract, respectively).
