RESUMO
Issue: Cultural safety enhances equitable communication between health care providers and cultural groups. Most documented cultural safety training initiatives focus on Indigenous populations from high-income countries, and nursing students, with little research activity reported from low- and middle-income countries. Several cultural safety training initiatives have been described, but a modern competency-based cultural safety curriculum is needed. Evidence: In this article, we present the Competency-Based Education and Entrustable Professional Activities frameworks of the Faculty of Medicine at La Sabana University in Colombia, and illustrate how this informed modernization of medical education. We describe our co-designed cultural safety training learning objectives and summarize how we explored its impact on medical education through mixed-methods research. Finally, we propose five cultural safety intended learning outcomes adapted to the updated curriculum, which is based on the Competency-Based Education model. Implications: This article presents five cultural safety intended learning outcomes for undergraduate medical education. These learning outcomes are based on Competency-Based Education and the Entrustable Professional Activities framework and can be used by faculties of medicine interested in including the cultural safety approach in their curriculum.
RESUMO
BACKGROUND: Available research on the contribution of traditional midwifery to safe motherhood focuses on retraining and redefining traditional midwives, assuming cultural prominence of Western ways. Our objective was to test if supporting traditional midwives on their own terms increases cultural safety (respect of Indigenous traditions) without worsening maternal health outcomes. METHODS: Pragmatic parallel-group cluster-randomised controlled non-inferiority trial in four municipalities in Guerrero State, southern Mexico, with Nahua, Na savi, Me'phaa and Nancue ñomndaa Indigenous groups. The study included all pregnant women in 80 communities and 30 traditional midwives in 40 intervention communities. Between July 2015 and April 2017, traditional midwives and their apprentices received a monthly stipend and support from a trained intercultural broker, and local official health personnel attended a workshop for improving attitudes towards traditional midwifery. Forty communities in two control municipalities continued with usual health services. Trained Indigenous female interviewers administered a baseline and follow-up household survey, interviewing all women who reported pregnancy or childbirth in all involved municipalities since January 2016. Primary outcomes included childbirth and neonatal complications, perinatal deaths, and postnatal complications, and secondary outcomes were traditional childbirth (at home, in vertical position, with traditional midwife and family), access and experience in Western healthcare, food intake, reduction of heavy work, and cost of health care. RESULTS: Among 872 completed pregnancies, women in intervention communities had lower rates of primary outcomes (perinatal deaths or childbirth or neonatal complications) (RD -0.06 95%CI - 0.09 to - 0.02) and reported more traditional childbirths (RD 0.10 95%CI 0.02 to 0.18). Among institutional childbirths, women from intervention communities reported more traditional management of placenta (RD 0.34 95%CI 0.21 to 0.48) but also more non-traditional cold-water baths (RD 0.10 95%CI 0.02 to 0.19). Among home-based childbirths, women from intervention communities had fewer postpartum complications (RD -0.12 95%CI - 0.27 to 0.01). CONCLUSIONS: Supporting traditional midwifery increased culturally safe childbirth without worsening health outcomes. The fixed population size restricted our confidence for inference of non-inferiority for mortality outcomes. Traditional midwifery could contribute to safer birth among Indigenous communities if, instead of attempting to replace traditional practices, health authorities promoted intercultural dialogue. TRIAL REGISTRATION: Retrospectively registered ISRCTN12397283 . Trial status: concluded.
In many Indigenous communities, traditional midwives support mothers during pregnancy, childbirth, and some days afterwards. Research involving traditional midwives has focused on training them in Western techniques and redefining their role to support Western care. In Guerrero state, Mexico, Indigenous mothers continue to trust traditional midwives. Almost half of these mothers still prefer traditional childbirths, at home, in the company of their families and following traditional practices. We worked with 30 traditional midwives to see if supporting their practice allowed traditional childbirth without worsening mothers' health. Each traditional midwife received an inexpensive stipend, a scholarship for an apprentice and support from an intercultural broker. The official health personnel participated in a workshop to improve their attitudes towards traditional midwives. We compared 40 communities in two municipalities that received support for traditional midwifery with 40 communities in two municipalities that continued to receive usual services. We interviewed 872 women with childbirth between 2016 and 2017. Mothers in intervention communities suffered fewer complications during childbirth and had fewer complications or deaths of their babies. They had more traditional childbirths and fewer perineal tears or infections across home-based childbirths. Among those who went to Western care, mothers in intervention communities had more traditional management of the placenta but more non-traditional cold-water baths. Supporting traditional midwifery increased traditional childbirth without worsening health outcomes. The small size of participating populations limited our confidence about the size of this difference. Health authorities could promote better health outcomes if they worked with traditional midwives instead of replacing them.

Problem: The Colombian government provides health services grounded in the Western biomedical model, yet 40% of the population use cultural and traditional practices to maintain their health. Adversarial interactions between physicians and patients from other cultures hinder access to quality health services and reinforce health disparities. Cultural safety is an approach to medical training that encourages practitioners to examine how their own culture shapes their clinical practice and how to respect their patients' worldviews. This approach could help bridge the cultural divide in Colombian health services, improving multicultural access to health services and reducing health disparities. Intervention: In 2016, we conducted a pilot cultural safety training program in Cota, Colombia. A five-month training program for medical students included: (a) theoretical training on cultural safety and participatory research, and (b) a community-based intervention, co-designed by community leaders, training supervisors, and the medical students, with the aim of strengthening cultural practices related to health. Evaluation used the Most Significant Change narrative approach, which allows participants to communicate the changes most meaningful to them. Using an inductive thematic analysis, the authors analyzed the stories and discussed these findings in a debriefing session with the medical students. Context: Cota is located only 15 kilometers from Bogota, the national capital and biggest city of Colombia, so the small town has gone through rapid urbanization and cultural change. A few decades ago, inhabitants of Cota were mainly peasants with Indigenous and European traditions. Urbanization displaced agriculture with industrial and commercial occupations. One consequence of this change was loss of cultural health care practices and resources, for example, medicinal plants, that the community had used for centuries. Impact: A group of 13 final-year medical students (ten female and three male, age range 20-24) participated in the study. The medical students listed four areas of change after their experience: increased respect for traditional health practices to provide better healthcare; increased recognition of traditional practices as part of their cultural heritage and identity; a desire to deepen their knowledge about cultural practices; and openness to incorporate cultural practices in healthcare. Lessons Learned: Medical students reported positive perceptions of their patients' cultural practices after participating in this community-based training program. The training preceded a positive shift in perceptions and was accepted by Colombian medical students. To the best of our knowledge, this was the first documented cultural safety training initiative with medical students in Colombia and an early attempt to apply the cultural safety approach outside the Indigenous experience.

Objetivo. Identificar factores demográficos y clínicos asociados con la mortalidad por dengue grave en cinco de-partamentos de Colombia. Material y métodos. Análisis secundario de un estudio de casos y controles basado en pa-cientes admitidos de 2009 a 2013. Los casos fueron pacientes que murieron por dengue y los controles fueron pacientes con dengue grave sobrevivientes a la enfermedad. Se utilizó el procedimiento de Mantel-Haenszel para identificar los factores. Resultados. Analizando 58 casos y 121 controles, cuatro factores fueron asociados con la mortalidad por den-gue: administración hospitalaria de dipirona (RMa=6.38 IC95% 2.41-16.86) y de acetaminofén (RMa=0.25 IC95% 0.10-0.61), presencia de comorbilidad (RMa=3.52 IC95% 1.51-8.18) y consulta previa por el mismo padecimiento (RMa=3.99 IC95% 1.63-9.77). Conclusiones. La administración de dipirona en pacientes con dengue grave se asoció con un aumento del riesgo de mortalidad. Si se considera que la dipirona fue retirada del mercado en 20 países por sus efectos secunda-rios, se puede desaconsejar su uso en el manejo del dengue.

Adult T-cell leukemia/lymphoma, an aggressive T-cell neoplasm, is causally linked to human T-cell lymphotropic virus type 1 and based on this association has a distinct geographic distribution. In our United States-based practice, whose population is enriched for immigrants from human T-cell lymphotropic virus type 1 endemic areas, we have identified that a subset of adult T-cell leukemia/lymphoma, in the absence of human T-cell lymphotropic virus type 1 identification, are indistinguishable from other more common T-cell neoplasms. We retrospectively gathered serology results for anti-human T-cell lymphotropic virus type 1/2 antibody in patients diagnosed with T-cell neoplasms at our institution. A total of 220 human T-cell lymphotropic virus type 1/2 positive patients with T-cell neoplasms were identified; 199 (91%) were correctly classified as adult T-cell leukemia/lymphoma or provisionally as peripheral T-cell lymphoma (serology testing pending). Twenty-one cases (9%) were initially misclassified, including the following: 13 presenting with skin +/- peripheral blood involvement and misclassified as mycosis fungoides/Sezary syndrome; 7 with lymphomatous disease, absence of leukemic involvement, and diffuse CD30 expression, misclassified as ALK- negative anaplastic large-cell lymphoma; 1 thought to represent T-prolymphocytic leukemia with TCL-1 gene rearrangement and diffuse marrow involvement. We also present an example of adult T-cell leukemia/lymphoma, which mimicked lymphoepithelioid variant of peripheral T-cell lymphoma also with diffuse marrow involvement. A subset of adult T-cell leukemia/lymphoma can closely mimic a variety of other more common T-cell neoplasms. Due to its extreme clinicopathologic heterogeneity, identification of adult T-cell leukemia/lymphoma requires a high level of suspicion based on patient demographic alone, which should prompt anti-human T-cell lymphotropic virus type 1/2 serology testing in all T-cell neoplasms developing in patients of appropriate demographic. Absence of high level of suspicion, adult T-cell leukemia/lymphoma is easily misclassified.

Epstein-Barr virus (EBV) -associated follicular lymphoma is only rarely reported. Herein, we report the largest series analyzing prevalence and clinicopathologic characteristics of EBV-associated follicular lymphoma occurring in unselected cases. Out of 382 analyzed cases, 10 EBV-positive follicular lymphomas were identified (prevalence=2.6%, 95% confidence interval 1.3-4.0%). All EBV-positive follicular lymphomas showed EBV-encoded small RNA-positive lymphoma cells present in a follicular distribution. Of these, eight also had tissue available for testing of expression of latent membrane protein 1 (LMP1), out of which six (75%) were positive. There was a significant association with grades 3A-3B follicular lymphoma (P<0.0001) and CD30 expression (P=0.0002). EBV-positive follicular lymphomas were otherwise morphologically and immunophenotypically indistinguishable from EBV-negative cases of similar grade. Nine of the EBV-positive follicular lymphomas occurred in patients with no known history of immunosuppression, while one patient had a history of hydroxychloroquine administration for Sjögren's syndrome. The mean age in the EBV-positive and -negative follicular lymphomas was 56 (range 31-83 years) and 49 years (range 25-92 years), respectively, with no statistically significant difference. Seven of the patients with EBV-positive follicular lymphoma had additional biopsies from different time points available for review, all of which showed progression of disease in the form of progression of tumor grade. Five of these progressed to diffuse large B-cell lymphoma, one of which had tissue available for testing and was EBV-positive. Our findings suggest that EBV infection may have a role in lymphomagenesis and/or disease progression in a subset of follicular lymphomas, thereby expanding the spectrum of recognized EBV-associated B-cell lymphomas.

The presence of >5% blasts at "day 14" (D14), in patients undergoing induction chemotherapy for acute myeloid leukemia (AML) is problematic. It is unclear if a second course of chemotherapy for early persistent disease will alter outcome in these patients. We conducted a retrospective study of AML patients undergoing induction chemotherapy where diagnostic, interim (around day 14), and recovery (days 21-42) bone marrow (BM) evaluations were available for review. Of the 113 patients included in the final analysis, 99 (87.6%) achieved CR at hematologic recovery. At D14, 90 patients (79.6%) had <5% blasts and of these, 87 (96.7%) ultimately achieved CR. At D14, Twenty-three (20.4%) patients had residual leukemia (>5% blasts). Of these, 11 (47.8%) received a second course of chemotherapy (double induction [DI]) and 12 (52.2%) were observed until count recovery (single induction [SI]). No significant difference in CR rates was observed between these two groups (58.3% DI group vs. 45.5% SI group, P value = 0.684). In our analysis, D14 BM evaluation did not uniformly identify patients with primary induction failure. To unequivocally determine the value of a D14 marrow assessment in AML, prospective studies in the context of large cooperative group trials are required. Considering our findings and similar reports from others, we propose that D14 marrow assessment should be individualized, and that other factors, such as cytogenetics and early peripheral blood blast clearance should be considered, to identify patients most likely to benefit from interim disease assessment during AML induction therapy.

UNLABELLED: Clinical presentation and histopathology of autoimmune hepatitis (AIH) and primary sclerosing cholangitis (PSC) overlap syndrome (OS) are similar, but their management is different. We conducted a pediatric retrospective cross-sectional study of 34 patients with AIH and PSC. AIH had female predominance (74%) and was lower in PSC (45%). There was a trend toward higher frequency of blacks in PSC/OS (55%) compared to Caucasians (36%) and Hispanics (9%), but not race differences in AIH. Inflammatory bowel disease (IBD) was present in 75% of PSC/OS. Plasma cells were not specific for AIH (found in 42% of PSC). Concentric fibrosis was not reliable for PSC as was found in 46% of AIH. CONCLUSION: A combination of clinical history, laboratory tests, imaging studies and liver biopsy are required to confirm and properly treat AIH and PSC. Liver biopsy should be used to grade severity and disease progression, but cannot be used alone to diagnose these conditions.

The function of the sense of taste is usually confined to the ability to perceive the flavor of food to assess and use the nutrients necessary for healthy survival and to discard those that may be harmful, toxic, or unpleasant. It is almost unanimously agreed that the perception of bitter taste prevents the consumption of toxins from plants, decaying foods, and drugs. Forty years ago, while practicing medicine in a rural area of the Colombian Amazon, I had an unexpected encounter with the Inga Indians. I faced the challenge of accepting that their traditional medicine was effective and that the medicinal plants they used had a real therapeutic effect. Wanting to follow a process of learning about medicinal plants on their terms, I found that, for them, the taste of plants is a primary and fundamental key to understanding their functioning. One of the most exciting results was discovering the therapeutic value of bitter plants. The present review aims to understand whether there is any scientific support for this hypothesis from the traditional world. Can the taste of plants explain their possible therapeutic benefit? In the last 20 years, we have made novel advances in the knowledge of the physiology of taste. Our purpose will be to explore these scientific advances to determine if the bitter taste of medicinal plants benefits human health.
RESUMO
INTRODUCTION: Cultural safety, interculturality and antiracism are crucial concepts in addressing health disparities of minority and diverse groups. Measuring them is challenging, however, due to overlapping meanings and their highly contextual nature. Community engagement is essential for evaluating these concepts, yet the methods for social inclusion and protocols for participation remain unclear. This review identifies experimental studies that measure changes resulting from culturally safe, intercultural or antiracist healthcare. The review will describe outcomes and additional factors addressed in these studies. METHODS AND ANALYSIS: The study focuses on epidemiological experiments with counterfactual comparisons and explicit interventions involving culturally safe, intercultural or antiracist healthcare. The search strategy covers PubMed, CINAHL, Scopus, Web of Science, ProQuest, LILACS and WHO IRIS databases. We will use critical appraisal tools from the Joanna Briggs Institute to assess the quality of randomised and non-randomised experimental studies. Two researchers will screen references, select studies and extract data to summarise the main characteristics of the studies, their approach to the three concepts under study and the reported effect measures. We will use fuzzy cognitive mapping models based on the causal relationships reported in the literature. We will consider the strength of the relationships depicted in the maps as a function of the effect measure reported in the study. Measures of centrality will identify factors with higher contributions to the outcomes of interest. Illustrative intervention modelling will use what-if scenarios based on the maps. ETHICS AND DISSEMINATION: This review of published literature does not require ethical approval. We will publish the results in a peer-reviewed journal and present them at conferences. The maps emerging from the process will serve as evidence-based models to facilitate discussions with Indigenous communities to further the dialogue on the contributing factors and assessment of cultural safety, interculturality and antiracism. PROSPERO REGISTRATION NUMBER: CRD42023418459.

Introduction: The Muisca Indigenous people in Cota, Colombia, has committed to reviving and strengthening their traditional culture, including the ancestral knowledge associated with their traditional medicine. Objective: To explore the occurrence of traditional medicine and factors associated with its use among the Muisca people in Cota, Colombia. Methods: A participatory cross-sectional study applied a questionnaire to 471 Muisca mothers who had at least one child over 10 in April 2019. The 44 questions inquired demographic, social, and cultural factors of participants and their knowledge, use and practice of traditional medicine. We used the Mantel-Haenszel procedure to measure the associations using Odds Ratio and 95% confidence intervals. Results: 66.2% (312/471) of the mothers knew at least three cases of traditional diseases; 56.8% (267/470) had and used medicinal plants; 15.8% (73/462) had practiced traditional self-care for flu, menstruation and postpartum; and 11.8% (54/458) reported that they had gone to midwives, bonesetters and healers. Four factors had a significant association (p < 0.05) with traditional medicine: consumption of three traditional foods; having traditional gardens and plants; living within the reservation; and parents born in a municipality of indigenous influence. Conclusions: The study showed that the permanence of traditional medicine is strongly associated with traditional food, agricultural vocation and the possession and use of medicinal plants. The results suggest that the strategy for the recovery of traditional medicine could focus on promoting a stronger link between indigenous identity, territory, food and health.
Introducción: La población del Resguardo Indígena Muisca de Cota, Colombia, se encuentra en un proceso de fortalecimiento cultural. Ahora busca la recuperación de sus saberes ancestrales relacionados con la medicina tradicional. Objetivo: Explorar la ocurrencia de la medicina tradicional y factores asociados con su vigencia en el resguardo indígena Muisca de Cota, Colombia. Métodos: Estudio transversal participativo con los miembros del resguardo. Para este estudio se aplicó en abril de 2019 un instrumento de 44 preguntas a 471 madres de familia que tenían por lo menos un hijo mayor de diez años. A través de él se indagaron algunos factores demográficos, sociales y culturales. Además, se plantearon preguntas relacionadas con conocimiento, uso y práctica de medicina tradicional. Usamos el procedimiento de Mantel-Haenszel para establecer las asociaciones mediante el Odds ratio e intervalos de confianza del 95%. Resultados: El 66,2% (312/471) de las madres conocía al menos tres casos de enfermedades tradicionales, el 56,8% (267/470) tenía y usaba plantas medicinales, el 15,8% (73/462) practicaba cuidados tradicionales de la gripa, la menstruación y el puerperio, y el 11,8% (54/458) reportó que han acudido a parteras, sobanderos y curanderos. El consumo de tres alimentos tradicionales, la tenencia de huertos y plantas tradicionales, tener la vivienda dentro del resguardo y padres nacidos en un municipio de influencia indígena, fueron los principales factores asociados con la prevalencia de la medicina tradicional (p < 0,05). Conclusiones: El estudio mostró que la permanencia de la medicina tradicional está fuertemente asociada a la alimentación tradicional, a la vocación agrícola y a la tenencia y uso de plantas medicinales. Los resultados sugieren que la estrategia de recuperación de la medicina tradicional podría enfocarse en promover un mayor vínculo entre identidad indígena, territorio, alimentación y salud.

Background: Although traditional and cultural health practices are widely used in Colombia, physicians are not trained to address intercultural tensions that arise in clinical practice. Cultural safety encourages practitioners to examine how their own culture shapes their clinical practice and to respect their patients' culture. It requires inviting patients of non-dominant cultures to co-design culturally safe health care. We co-designed a curriculum for cultural safety training of Colombian health professionals. Methods: A sequential-consensual qualitative study defined the learning objectives of the curriculum. Semi-structured questionnaires and focus groups explored the opinions of traditional medicine users, medical students, and intercultural health experts to inform the content of the curriculum. Deliberative dialogue between key intercultural health experts settled the academic content of the curriculum. A member-checking strategy modified and approved the final version. Results: Seven traditional medicine users, six medical students, and four intercultural health experts participated in the study. The stakeholders defined five learning objectives: (a) culturally unsafe practices: acknowledge the intercultural tensions and its consequences; (b) cultural awareness: examine their attitudes, beliefs, and values, and how they shape their professional practice; (c) cultural humility: listen and learn from the patients' traditional practices; (d) cultural competence: describe current pedagogical approaches to address intercultural tensions; and (e) cultural safety: discuss with patients to reach an agreement on their treatment. Conclusion: This study integrated the perspectives of different stakeholders and proposed new applications of cultural safety that are relevant to other countries. Researchers and educators can use these results to inform future cultural safety initiatives.
Contexte: Bien que les pratiques traditionnelles et culturelles en matière de santé soient largement utilisées en Colombie, les médecins ne sont pas formés pour faire face aux tensions interculturelles qui peuvent surgir dans le contexte clinique. La sécurité culturelle encourage les praticiens à s'interroger sur les façons dont leur propre culture influence leur pratique clinique et à respecter la culture de leurs patients. Elle exige qu'ils invitent leurs patients de cultures non dominantes à co-concevoir des soins de santé culturellement sûrs. Nous avons co-conçu un programme de formation en sécurité culturelle pour les professionnels de santé colombiens. Méthodes: Les objectifs d'apprentissage du programme ont été définis sur la base d'une étude qualitative séquentielle-consensuelle. Par le biais de questionnaires semi-structurés et de groupes de discussion, nous avons exploré les opinions d'utilisateurs de la médecine traditionnelle, d'étudiants en médecine et d'experts en santé interculturelle dans le but de définir le contenu du cursus de façon éclairée. Son contenu académique a été finalisé à la suite d'un dialogue délibératif entre les principaux experts en santé interculturelle. Une vérification par les membres a permis de modifier et d'approuver la version finale. Résultats: Sept utilisateurs de la médecine traditionnelle, six étudiants en médecine et quatre experts en santé interculturelle ont participé à l'étude. Les parties prenantes ont défini cinq objectifs d'apprentissage : (a) pratiques culturellement non sécuritaires : reconnaître les tensions interculturelles et leurs conséquences; (b) prise de conscience culturelle : examiner leurs attitudes, croyances et valeurs, et la manière dont elles façonnent s pratiques professionnelles; (c) humilité culturelle : écouter et apprendre des pratiques traditionnelles des patients; (d) compétence culturelle : décrire les approches pédagogiques actuelles sur la question des tensions interculturelles; et (e) sécurité culturelle : discuter avec les patients pour parvenir à un terrain d'entente sur leur traitement. Conclusion: Cette étude intègre les perspectives de différentes parties prenantes et propose de nouvelles applications de la sécurité culturelle qui seraient également pertinentes dans d'autres pays. Les chercheurs et les enseignants peuvent utiliser ces résultats pour alimenter des initiatives futures en matière de sécurité culturelle.
RESUMO
INTRODUCTION: The prevalence of childhood asthma has increased in recent years. The World Health Organization has called for conducting research exploring the role of traditional medicine and medicinal plants in respiratory disease control. OBJECTIVE: To identify the relationship between the prevalence of childhood asthma and traditional care of the respiratory system, including cultivation and use of medicinal plants. METHODS: We conducted an observational, analytic, case-control study that included children 2 to 14 years old who used official health services in eight municipalities near Bogota between 2014 and 2015. Cases were children diagnosed with asthma. We randomly selected the controls among the remaining patients of the same healthcare facilities. We applied an 18-question survey. The Mantel-Haenszel procedure identified significant associations using 95% confidence intervals. RESULTS: We surveyed the caretakers of 97 cases and 279 controls in eight municipalities. Some 23.4% (88/376) and 37.9% (142/375) reported using traditional remedies for fever control and common cold management, respectively. 8.8% (33/376) reported following traditional care during a common cold, 30.4% (114/375) reported growing medicinal plants at home, and 45% (166/369) reported using medicinal plants for health purposes in their household. Multivariate analysis showed that having and using medicinal plants at home is associated with a lower reporting of asthma (odds ratio 0.49; 95% confidence interval: 0.25 to 0.99). CONCLUSIONS: Cultivating and using medicinal plants at home is associated with a lower reporting of childhood asthma. Researchers should consider the therapeutic, environmental, and cultural properties of medicinal plants to prevent respiratory diseases.
INTRODUCCIÓN: La prevalencia de asma infantil ha aumentado en los últimos años. La Organización Mundial de la Salud invita a buscar evidencia científica en las medicinas tradicionales y el uso de plantas medicinales, como contribución al control de las enfermedades respiratorias. OBJETIVOS: Identificar la relación entre prevalencia de asma infantil y cuidados respiratorios tradicionales, incluyendo el cultivo y uso de plantas medicinales. MÉTODOS: Estudio observacional, analítico con diseño de casos y controles en niños (de 2 a 14 años) atendidos por servicios estatales de salud en ocho municipios vecinos a Bogotá durante 2014 y 2015. Fueron casos quienes recibieron diagnóstico de asma y se seleccionaron los controles aleatoriamente entre los demás usuarios de las mismas instituciones. Aplicamos un cuestionario con 18 preguntas. La prueba de Mantel-Haenszel identificó asociaciones significativas usando el Odds ratio e intervalos de confianza del 95%. RESULTADOS: Encuestamos a los acudientes de 97 casos y 279 controles en ocho municipios. El 23,4% (88/376) reportó el uso de remedios caseros para controlar la fiebre y el 37,9% (142/375) para manejar la gripe. El 8,8% (33/376) reportó cumplir con todos los cuidados del frío durante la gripe; 30,4% (114/375) tiene plantas medicinales sembradas en su vivienda y 45% (166/369) reportó uso de plantas medicinales para el cuidado de la salud en el hogar. El análisis multivariado mostró que la tenencia y uso de plantas medicinales en la vivienda se asoció con menor reporte de asma (Odds ratio: 0,49; intervalo de confianza 95%: 0,25 a 0,99). CONCLUSIONES: Cultivar y usar plantas medicinales en los hogares está asociado con menor reporte de asma infantil. Conviene considerar las propiedades terapéutica, ambiental y cultural de las plantas medicinales para la prevención de enfermedades respiratorias.

OBJECTIVES: Collate published evidence of factors that affect maternal health in Indigenous communities and contextualise the findings with stakeholder perspectives in the Mexican State of Guerrero. DESIGN: Scoping review and stakeholder fuzzy cognitive mapping. INCLUSION AND EXCLUSION: The scoping review included empirical studies (quantitative, qualitative or mixed methods) that addressed maternal health issues among Indigenous communities in the Americas and reported on the role or influence of traditional midwives before June 2020. The contextualisation drew on two previous studies of traditional midwife and researcher perspectives in southern Mexico. RESULTS: The initial search identified 4461 references. Of 87 selected studies, 63 came from Guatemala and Mexico. Three small randomised trials involved traditional midwives. One addressed the practice of traditional midwifery. With diverse approaches to cultural differences, the studies used contrasting definitions of traditional midwives. A fuzzy cognitive map graphically summarised the influences identified in the scoping review. When we compared the literature's map with those from 29 traditional midwives in Guerrero and eight international researchers, the three sources coincided in the importance of self-care practices, rituals and traditional midwifery. The primary concern reflected in the scoping review was access to Western healthcare, followed by maternal health outcomes. For traditional midwives, the availability of hospital or health centre in the community was less relevant and had negative effects on other protective influences, while researchers conditioned its importance to its levels of cultural safety. Traditional midwives highlighted the role of violence against women, male involvement and traditional diseases. CONCLUSIONS: The literature and stakeholder maps showed maternal health resulting from complex interacting factors in which promotion of cultural practices was compatible with a protective effect on Indigenous maternal health. Future research challenges include traditional concepts of diseases and the impact on maternal health of gender norms, self-care practices and authentic traditional midwifery.

INTRODUCTION: The Paris System (TPS) for reporting urine cytology was developed for standardization of diagnosis focusing on the detection of high-grade urothelial carcinoma (HGUC). Probably the most challenging task for TPS is to provide criteria for the atypical urothelial cell (AUC) category. The TPS criteria for AUC include increased nuclear/cytoplasmic (N/C) ratio (>0.5) and 1 of the 3 minor criteria including nuclear hyperchromasia (NH), coarse chromatin (CC) and irregular nuclear membrane (INM). We evaluated TPS-AUC diagnostic value and investigated whether other morphologic parameters can improve its criteria. MATERIALS AND METHODS: Urine samples with diagnoses of AUC collected during a 6-month period were re-reviewed. Data captured included N/C ratio >0.5, NH, CC, INM, and 2 additional criteria including enlarged nuclear size (ENS) and the presence of nucleolus (N). ENS was considered when the nucleus was 2 times larger than the urothelial cell or 3 times larger than lymphocyte. RESULTS: By applying the TPS-AUC criteria, the rate of atypia diagnosis reduced in comparison to Pre-TPS (9% versus 13%, P = 0.02). Among the AUC minor criteria, NH was the best criterion with the highest interobserver agreement (IOA) and correlation with HGUC (k = 0.342, r = 0.61, P < 0.001) and strong PPV (93.6%). ENS had the highest PPV (95.8%) and, after NH, had the highest IOA and correlation with HGUC (k = 0.29, r = 0.52, P < 0.001). CONCLUSION: TPS improves the diagnostic value of urine cytology, particularly in cases with atypia. ENS is a strong criterion for increasing the diagnostic value of AUC and potentially can improve TPS performance as a minor criterion.

For more than a decade, flow cytometry-based automated haematology analysers have been studied for malaria diagnosis. Although current haematology analysers are not specifically designed to detect malaria-related abnormalities, most studies have found sensitivities that comply with WHO malaria-diagnostic guidelines, i.e. ≥ 95% in samples with > 100 parasites/µl. Establishing a correct and early malaria diagnosis is a prerequisite for an adequate treatment and to minimizing adverse outcomes. Expert light microscopy remains the 'gold standard' for malaria diagnosis in most clinical settings. However, it requires an explicit request from clinicians and has variable accuracy. Malaria diagnosis with flow cytometry-based haematology analysers could become an important adjuvant diagnostic tool in the routine laboratory work-up of febrile patients in or returning from malaria-endemic regions. Haematology analysers so far studied for malaria diagnosis are the Cell-Dyn®, Coulter® GEN·S and LH 750, and the Sysmex XE-2100® analysers. For Cell-Dyn analysers, abnormal depolarization events mainly in the lobularity/granularity and other scatter-plots, and various reticulocyte abnormalities have shown overall sensitivities and specificities of 49% to 97% and 61% to 100%, respectively. For the Coulter analysers, a 'malaria factor' using the monocyte and lymphocyte size standard deviations obtained by impedance detection has shown overall sensitivities and specificities of 82% to 98% and 72% to 94%, respectively. For the XE-2100, abnormal patterns in the DIFF, WBC/BASO, and RET-EXT scatter-plots, and pseudoeosinophilia and other abnormal haematological variables have been described, and multivariate diagnostic models have been designed with overall sensitivities and specificities of 86% to 97% and 81% to 98%, respectively. The accuracy for malaria diagnosis may vary according to species, parasite load, immunity and clinical context where the method is applied. Future developments in new haematology analysers such as considerably simplified, robust and inexpensive devices for malaria detection fitted with an automatically generated alert could improve the detection capacity of these instruments and potentially expand their clinical utility in malaria diagnosis.

OBJECTIVES: This study explored motivation dynamics of medical students engaging with traditional medicine in Colombia. METHODS: We conducted a qualitative descriptive study as part of a larger participatory research effort to develop a medical education curriculum on cultural safety. Four final-year medical students participated in a five-month program to strengthen knowledge of traditional medicinal plants with schoolchildren in Cota, a municipality outside Bogota with a high proportion of traditional medicine users. Students and schoolteachers co-designed the program aimed to promote the involvement of school children with traditional medicine in their community. The medical students shared written narratives describing what facilitated their work and discussed experiences in a group session. Inductive thematic analysis of the narratives and discussion derived categories of motivation to learn about traditional medicine. RESULTS: Five key learning dynamics emerged from the analysis: (1) learning from/with communities as opposed to training them; (2) ownership of medical education as a result of co-designing the exercise; (3) rigorous academic contents of the program; (4) lack of cultural safety training in university; and (5) previous contacts with traditional knowledge. CONCLUSIONS: We identified potential principles for engaged cultural safety training for medical students. We will use these in our larger training program. Our results may be relevant to other researchers and medical educators wanting to improve the interaction of medical health professionals in multicultural settings with people and communities who use traditional medicine. We expect these professionals will be better prepared to recognize and address intercultural challenges in their clinical practice.

Indigenous communities in Latin America and elsewhere have complex bodies of knowledge, but Western health services generally approach them as vulnerable people in need of external solutions. Intercultural dialogue recognises the validity and value of Indigenous standpoints, and participatory research promotes reciprocal respect for stakeholder input in knowledge creation.As part of their decades-long community-based work in Mexico's Guerrero State, researchers at the Centro de Investigación de Enfermedades Tropicales responded to the request from Indigenous communities to help them address poor maternal health. We present the experience from this participatory research in which both parties contributed to finding solutions for a shared concern. The aim was to open an intercultural dialogue by respecting Indigenous skills and customs, recognising the needs of health service stakeholders for scientific evidence.Three steps summarise the opening of intercultural dialogue. Trust building and partnership based on mutual respect and principles of cultural safety. This focused on understanding traditional midwifery and the cultural conflicts in healthcare for Indigenous women. A pilot randomised controlled trial was an opportunity to listen and to adjust the lexicon identifying and testing culturally coherent responses for maternal health led by traditional midwives. Codesign, evaluation and discussion happened during a full cluster randomised trial to identify benefits of supporting traditional midwifery on maternal outcomes. A narrative mid-term evaluation and cognitive mapping of traditional knowledge offered additional evidence to discuss with other stakeholders the benefits of intercultural dialogue. These steps are not mechanistic or invariable. Other contexts might require additional steps. In Guerrero, intercultural dialogue included recovering traditional midwifery and producing high-level epidemiological evidence of the value of traditional midwives, allowing service providers to draw on the strengths of different cultures.

Head and neck carcinomas with basaloid features can be diagnostically challenging. A common diagnostic issue is the distinction between a basaloid squamous cell carcinoma (bSCC) and a basal cell carcinoma (BCC) of cutaneous origin. This is particularly true in small biopsy specimens where classic architectural and histologic features may be difficult to appreciate. A specific diagnosis is essential because of significant differences in clinical outcome and therapeutic management. Ten resection cases of bSCC and BCC of the head and neck were selected based on primary location and the classic morphologic features that characterize these 2 entities. The following immunohistochemical markers were evaluated: epithelial membrane antigen (EMA), Ber-EP4, CD44, Bcl2, androgen receptor, SOX2, and p16. The strongest statistically significant differences in staining patterns were for EMA, p16, and SOX2. EMA was positive in all bSCCs and negative in all BCCs. SOX2 was positive in all bSCCs and in only 3 out of 10 BCCs. Staining was weak and peripheral in the SOX2-positive BCCs. p16 was positive in 8 out of 10 bSCCs and negative in all BCCs. We conclude that bSCC and BCC of the head and neck can be readily distinguished by a limited panel consisting primarily of EMA, and supported by SOX2 and p16.

Frozen section telepathology interpretation experience has been largely limited to practices with locations significantly distant from one another with sporadic need for frozen section diagnosis. In 2010, we established a real-time nonrobotic telepathology system in a very active cancer center for daily frozen section service. Herein, we evaluate its accuracy compared to direct microscopic interpretation performed in the main hospital by the same faculty and its cost-efficiency over a 1-year period. From 643 (1,416 parts) cases requiring intraoperative consultation, 333 cases (690 parts) were examined by telepathology and 310 cases (726 parts) by direct microscopy. Corresponding discrepancy rates were 2.6% (18 cases: 6 [0.9%] sampling and 12 [1.7%] diagnostic errors) and 3.2% (23 cases: 8 [1.1%] sampling and 15 [2.1%] diagnostic errors), Pâ¯=â¯.63. The sensitivity and specificity of intraoperative frozen diagnosis were 0.92 and 0.99, respectively, in telepathology and 0.90 and 0.99, respectively, in direct microscopy. There was no correlation of error incidence with postgraduate year level of residents involved in the telepathology service. Cost analysis indicated that the time saved by telepathology was $19,691.00 over 1 year of the study period, whereas the capital cost for establishing the system was $8,924.00. Thus, real-time nonrobotic telepathology is a reliable and easy-to-use tool for frozen section evaluation in busy clinical settings, especially when frozen section service involves more than one hospital, and it is cost-efficient when travel is a component of the service.
