ABSTRACT OBJECTIVE To evaluate the performance of tuberculosis control in Brazilian municipalities. METHODS This is an ecological study on Brazilian municipalities that notified at least four new cases of tuberculosis, with a minimum of one new case of pulmonary tuberculosis between 2015 and 2018. The municipalities were stratified according to the population in < 50 thousand, 50–100 thousand, 100–300 thousand, and > 300 thousand inhabitants, and the k-means method was used to group them within each population range according to the performance of six indicators of the disease. RESULTS A total of 2,845 Brazilian municipalities were included, comprising 98.5% (208,007/211,174) of new tuberculosis cases in the period. For each population range, three groups (A, B, and C) of municipalities were identified according to the performance of the indicators: A, the most satisfactory; B, the intermediates; and C, the least satisfactory. Municipalities in group A with < 100 thousand inhabitants presented results above the targets for laboratory confirmation (≥ 72%), abandonment (≤ 5%), and cure (≥ 90%), and comprised 2% of new cases of the disease. Conversely, municipalities of groups B and C presented at least five indicators with results below the targets – HIV testing (< 100%), contact investigation (< 90%), directly observed therapy (< 90%), abandonment (> 5%), and cure (< 90%) –, and corresponded to 66.7% of new cases of tuberculosis. In group C of municipalities with > 300 thousand inhabitants, which included 19 of the 27 capitals and 43.1% of new cases of tuberculosis, the lowest percentages of contact investigation (mean = 56.4%) and directly observed therapy (mean = 15.4%) were verified, in addition to high abandonment (mean = 13.9%) and low coverage of primary health care (mean = 66.0%). CONCLUSIONS Most new cases of tuberculosis occurred in municipalities with unsatisfactory performance for disease control. Expanding the coverage of primary health care in these places can reduce abandonment and increase the contact investigation and directly observed therapy.

RESUMO OBJETIVO Avaliar o desempenho no controle da tuberculose dos municípios brasileiros. MÉTODOS Estudo ecológico com municípios brasileiros que notificaram pelo menos quatro casos novos de tuberculose, com no mínimo um caso novo de tuberculose pulmonar entre 2015 e 2018. Os municípios foram estratificados de acordo com a população em < 50 mil, 50–100 mil, 100–300 mil e > 300 mil habitantes e foi utilizado o método k-médias para agrupá-los dentro de cada faixa populacional segundo desempenho de seis indicadores da doença. RESULTADOS Foram incluídos 2.845 municípios brasileiros abrangendo 98,5% (208.007/211.174) dos casos novos de tuberculose do período. Para cada faixa populacional identificou-se três grupos (A, B e C) de municípios segundo desempenho dos indicadores: A os mais satisfatórios, B os intermediários e C os menos satisfatórios. Municípios do grupo A com < 100 mil habitantes apresentaram resultados acima das metas para confirmação laboratorial (≥ 72%), abandono (≤ 5%) e cura (≥ 90%), e abrangeram 2% dos casos novos da doença. Por outro lado, os municípios dos grupos B e C apresentaram pelo menos cinco indicadores com resultados abaixo das metas – testagem HIV (< 100%), exame de contatos (< 90%), tratamento diretamente observado (< 90%), abandono (> 5%) e cura (< 90%) –, e corresponderam a 66,7% dos casos novos de tuberculose. Já no grupo C dos municípios com > 300 mil habitantes, que incluiu 19 das 27 capitais e 43,1% dos casos novos de tuberculose, encontrou-se os menores percentuais de exames de contatos (média = 56,4%) e tratamento diretamente observado (média = 15,4%), elevado abandono (média = 13,9%) e baixa cobertura da atenção básica (média = 66,0%). CONCLUSÕES Grande parte dos casos novos de tuberculose ocorreu em municípios com desempenho insatisfatório para o controle da doença, onde expandir a cobertura da atenção básica pode reduzir o abandono e elevar o exame de contatos e tratamento diretamente observado.

Abstract Aim of the study: Laparoscopic adhesiolysis in small bowel obstruction (SBO) is getting increasingly normal. In patients with multiple adhesive SBOs (MASBO), laparoscopic approaches might increase the risk of bowel injury due to the distended and potentially compromised small bowel. It remains a challenge to the surgeons, entails an interdisciplinary team, trying to achieve the least complications as possible. The study aimed to compare surgical outcomes of laparoscopic procedures (multi-port vs. single-port) in the management of MASBO. Patients and Methods: Comparative study of 68 patients with post-operative MASBO treated with Single-Port single incision laparoscopic surgery (SILS) and Multi-port Laparoscopic Surgery in two centers of Bogota, Colombia between January 2013 and June 2018. Results: All patients underwent laparoscopic management, 27 patients by SILS, and 41 patients by multi-port. The average surgical time in the multiport approach was 167 min versus SILS with 129 min. Laparoscopic intestinal resection was performed in 4.4% of patients, through multi-port using intracorporeal anastomosis. Mean hospital stay of 3.2 days for the SILS approach versus multi-port in 2.2 days. Conclusions: Both laparoscopic approaches, in MASBO treatment is feasible in qualified hands. Patient selection and medical judgment seem to be the most essential factors for a positive result.

Resumen Objetivos del estudio: Cada día es más frecuente la adherensiolisis laparoscópica en obstrucción del intestino delgado. En pacientes con obstrucciones debidas a múltiples adherencias del intestino delgado (OMAID), los abordajes laparoscópicos pueden incrementar el riesgo de daño de víscera hueca debido a la presencia de asas distendidas. Continúa siendo un reto para el cirujano, requiriendo un grupo interdisciplinario para disminuir las posibles complicaciones. Este estudio busca comparar los desenlaces de abordajes laparoscópicos (Multipuerto vs. monopuerto) en el manejo del OMAID. Pacientes y métodos: Se realizó un estudio de 68 pacientes con OMAID postoperatorio tratado con cirugía laparoscópica de monopuerto y múltipuerto en dos centros de Bogotá, Colombia entre enero de 2013 y junio de 2018. Resultados: Pacientes llevados a manejo laparoscópico, 27 por monopuerto y 41 por múltipuerto, con tiempo quirúrgico promedio de 129 y 167 minutos respectivamente. 4.1% de los pacientes requirieron resección intestinal, todas en pacientes con abordaje múltipuerto con anastomosis intracorpóreas. El tiempo medio de hospitalización fue de 3.2 días para monopuerto y 2.2 días para multipuerto. Conclusiones: Ambos abordajes laparoscópicos son factibles para el manejo del OMAID en manos calificadas. La selección del paciente y el juicio médico parecen ser factores fundamentales en el resultado positivo.

Abstract Objective: This study aimed to describe clinical outcomes of anterolateral thigh (ALT) and radial forearm flap in hypopharyngeal and esophageal reconstruction in a fourth level hospital in Bogotá, Colombia. Methods: This retrospective study included 38 patients who esophageal functional reconstruction using radial forearm or ALT flap at our center between February 2010 and December 2017. Results: Mean age was 51 years. About 80% of the included patients were females. Laryngoesophageal defects were present in 80%. Total circumferential reconstruction was required in 60% of patients. Brachial-radial grafts were performed in 26% and anterolateral thigh flaps in 74%. Overall, early complication rate was 30%, which 20% were fistulae (brachial-radial, 2.8%; ALT free flap, 8.3%). Late complications (20%) included stenosis and distal graft lumen obstruction. Only 10% of patients were unable to tolerate oral feeding and 50% of this patient needed permanent gastrostomy. Regarding oncological follow-up during the 24-month post-operative, no tumor recurrence was observed. Conclusions: Functional outcomes of reconstruction with brachial-radial and ALT flap were satisfying. Our findings suggest that ALT has a lower incidence of post-operative complications than radial forearm flap. The choice of the type of flap will depend on the size and location of the defect. Small and partially covered defects benefit from the use of a radial flap, and for larger and circumferential pharyngeal reconstructions with possible radiotherapy requirements, they benefit from an ALT flap.

Resumen Objetivo: Este estudio tuvo como objetivo describir los resultados clínicos del colgajo anterolateral de muslo y radial de antebrazo, para la reconstrucción hipofaríngea y esofágica en un hospital de cuarto nivel en Bogotá, Colombia. Métodos: Estudio retrospectivo inlcuyo 38 pacientes a los que se les realizó reconstrucción funcional esofágica con colgajo de antebrazo radial o anterolateral de muslo (ALT) entre febrero de 2010 y diciembre de 2017. Resultados: Edad media fue de 51 años. El 80% genero femeninp. Los defectos laringoesofágicos estuvieron presentes en el 80%. Se requirió reconstrucción circunferencial total en el 60% de los pacientes. Se realizaron injertos braquio-radiales en el 26% y colgajos anterolaterales de muslo en el 74%. La tasa global de complicaciones tempranas fue del 30%, de las cuales el 20% fueron fístulas (braquio-radial, 2,8%; colgajo libre de ALT, 8,3%). Las complicaciones tardías (20%) incluyeron estenosis y obstrucción de la luz del injerto distal. Solo el 10% de los pacientes no pudieron tolerar la alimentación oral y el 50% de este paciente necesitó gastrostomía permanente. En cuanto al seguimiento oncológico durante el postoperatorio de 24 meses, no se observó recidiva tumoral. Conclusión: Los resultados funcionales de la reconstrucción con colgajo braquio-radial y ALT fueron satisfactorios. Nuestros hallazgos sugieren que la ALT tiene una menor incidencia de complicaciones posoperatorias que el colgajo radial de antebrazo. La elección del tipo de colgajo dependerá del tamaño y la ubicación del defecto. Los defectos pequeños y parcialmente cubiertos se benefician del uso de un colgajo radial, y para reconstrucciones faríngeas más grandes y circunferenciales con posibles requisitos de radioterapia, se benefician de un colgajo ALT.

Resumen El trauma esofágico es un evento poco frecuente pero potencialmente mortal. Una perforación esofágica inadvertida puede ocasionar la rápida contaminación del cuello, el mediastino, el espacio pleural o la cavidad abdominal, lo cual puede resultar en sepsis o choque séptico. Las complicaciones y la mortalidad aumentan con el retraso en el diagnóstico o manejo definitivo, y la presencia de lesiones asociadas. El objetivo del presente artículo es describir la experiencia adquirida por el grupo de cirugía de Trauma y Emergencias (CTE) de Cali, Colombia en el manejo del trauma de esófago de acuerdo con los principios de la cirugía de control de daños. Las lesiones esofágicas deben sospecharse en todo trauma toraco-abdominal o cervical en el que el mecanismo o la trayectoria de la lesión lo sugieran. El paciente hemodinámicamente estable se debe estudiar con imágenes diagnósticas antes de la corrección quirúrgica del defecto, idealmente por medio de tomografía computarizada del cuello, tórax y abdomen con contraste endovenoso. Mientras que en el paciente hemodinámicamente inestable se debe explorar y controlar la lesión. El reparo primario es el manejo quirúrgico de elección, con la previa colocación de una sonda nasogástrica y el seguimiento postoperatorio estricto en la unidad de cuidado intensivo. Se propone un algoritmo de manejo quirúrgico que resulta fácil de seguir y adopta la premisa "Menos es Mejor" evitando realizar derivaciones esofágicas.

Abstract Esophageal trauma is a rare but life-threatening event associated with high morbidity and mortality. An inadvertent esophageal perforation can rapidly contaminate the neck, mediastinum, pleural space, or abdominal cavity, resulting in sepsis or septic shock. Higher complications and mortality rates are commonly associated with adjacent organ injuries and/or delays in diagnosis or definitive management. This article aims to delineate the experience obtained by the Trauma and Emergency Surgery Group (CTE) of Cali, Colombia, on the surgical management of esophageal trauma following damage control principles. Esophageal injuries should always be suspected in thoracoabdominal or cervical trauma when the trajectory or mechanism suggests so. Hemodynamically stable patients should be radiologically evaluated before a surgical correction, ideally with computed tomography of the neck, chest, and abdomen. While hemodynamically unstable patients should be immediately transferred to the operating room for direct surgical control. A primary repair is the surgical management of choice in all esophageal injuries, along with endoscopic nasogastric tube placement and immediate postoperative care in the intensive care unit. We propose an easy-to-follow surgical management algorithm that sticks to the philosophy of "Less is Better" by avoiding esophagostomas.

Resumo: O estudo teve com objetivos descrever as tendências na taxa de detecção de casos novos (TDCN) de hanseníase no Brasil em 2006-2017, global e por subgrupos, e analisar a evolução das características clínicas e terapêuticas dos pacientes, com ênfase nos casos diagnosticados com incapacidade física grau 2. Realizamos um estudo descritivo par analisar casos novos de hanseníase registrados no Sistema de Informação de Agravos de Notificação (SINAN), 2006-2017. Calculamos a TDCN de hanseníase por 100.000 habitantes (global e para indivíduos < 15 e ≥ 15 anos de idade) por sexo, idade, raça/etnicidade, área urbana/rural e macrorregião do Brasil e estimamos as tendências com o teste não paramétrico de Mann-Kendall. Analisamos as distribuições de casos de acordo com características clínicas relevantes ao longo do tempo. No Brasil, houve uma queda marcante na TDCN global, de 23,4/100.000 em 2006 para 10,3/100.000 em 2017; entre crianças < 15 anos, de 6,94 para 3,20/100.000. A queda foi consistente em todas a regiões brasileiras e em todas as categorias de raça/etnicidade. Até 2017, 70,2% dos casos eram multibacilares, 30,5% apresentavam incapacidades físicas grau 1 (G1D) ou grau 2 (G2D) ao diagnóstico e 42,8% não foram avaliados ao encerramento do tratamento ou alta; os casos com G2D ao diagnóstico foram detectados majoritariamente nas áreas urbanas (80%), e 5% dos casos faleceram durante o tratamento (devido à hanseníase ou por outras causas). Embora a frequência da TDCN da hanseníase tenha diminuído no Brasil entre 2006 e 2017 em todos os grupos avaliados, o número grande de casos com hanseníase multibacilar, incapacidades físicas ou sem avaliação adequada e entre crianças sugere a necessidade de reforçar o diagnóstico e tratamento oportunos para controlar a hanseníase no Brasil.

Abstract: Our study aims to describe trends in new case detection rate (NCDR) of leprosy in Brazil from 2006 to 2017 overall and in subgroups, and to analyze the evolution of clinical and treatment characteristics of patients, with emphasis on cases diagnosed with grade 2 physical disabilities. We conducted a descriptive study to analyze new cases of leprosy registered in the Brazilian Information System for Notificable Diseases (SINAN), from 2006-2017. We calculated the leprosy NCDR per 100,000 inhabitants (overall and for individuals aged < 15 and ≥ 15 years) by sex, age, race/ethnicity, urban/rural areas, and Brazilian regions, and estimated the trends using the Mann-Kendall non-parametric test. We analyzed the distributions of cases according to relevant clinical characteristics over time. In Brazil, there was a sharp decrease in the overall NCDR from 23.4/100,000 in 2006 to 10.3/100,000 in 2017; among children < 15 years, from 6.94 to 3.20/100,000. The decline was consistent in all Brazilian regions and race/ethnicity categories. By 2017, 70.2% of the cases were multibacillary, 30.5% had grade 1 (G1D) or 2 (G2D) physical disabilities at diagnosis and 42.8% were not evaluated at treatment completion/discharge; cases with G2D at diagnosis were mostly detected in urban areas (80%) and 5% of cases died during the treatment (leprosy or other causes). Although the frequency of leprosy NCDR decreased in Brazil from 2006 to 2017 across all evaluated population groups, the large number of cases with multibacillary leprosy, physical disabilities or without adequate evaluation, and among children suggest the need to reinforce timely diagnosis and treatment to control leprosy in Brazil.

Resumen Candida spp. es un agente etiológico importante en infecciones del tracto urinario, principalmente en población con terapia antimicótica de amplio espectro y con catéteres urinarios. Candida albicans es la especie más frecuente, pero otras especies han surgido como patógenos emergentes. En este trabajo se recolectaron aislamientos de Candida spp. de urocultivos de pacientes que consultaron en Dinamica IPS entre enero 2016 y noviembre 2017. Para estimar la frecuencia de las especies y observar los patrones de sensibilidad, se realizó la identificación fenotípica y su perfil de sensibilidad con el sistema comercial Vitek 2® (BioMérieux, Inc.), adicionalmente se evaluaron mediante análisis de las secuencia y filogenética ITS1-5.8S-ITS2. En el estudio se incluyeron 78 aislamientos de Candida spp. Las frecuencias de especies de Candida identificadas empleando las herramientas moleculares fueron: C. albicans (38,5%), C. tropicalis (23,1%), C. glabrata (21,8%), C. parapsilosis (10,3%), C. metapsilosis y C. krusei (2,5%) y C. guillermondi (1,3%). La identificación por métodos moleculares y por el sistema Vitek 2 fue: C. albicans (93,3%), C. glabrata (94,1%), C. tropicalis (83,3%), C. parapsilosis (75%) C. guilliermondii y C. krusei (100%). La sensibilidad de todos los aislamientos al fluconazol fue 93,6%.

Abstract Candida spp is an important etiologic agent in urinary tract infections, mainly in patients in broad-spectrum antifungal therapy, with urinary catheters. Candida albicans is the most frequent specie; but other species have arised as emerging pathogens. In this study, isolates of Candida spp. of urine cultures from patients who consulted in Dinamica IPS between January 2016 and November 2017 were evaluated. To estimate the frequency of the species and to observe the sensitivity patterns, the phenotypic identification and its sensitivity profile was performed employed the Vitek 2® commercial system. (BioMérieux, Inc) In addition the isolates were evaluated by sequence analysis and phylogenetics ITS1-5.8S-ITS2. This study included 78 isolates of Candida spp. The frequencies of Candida species identified using the molecular tools were: C. albicans (38.5%), C. tropicalis (23.1%), C. glabrata (21.8%), C. parapsilosis (10.3%), C. guillermondi (1.3%) and C. metapsilosis and C. krusei (2.5%). The identification by molecular methods and by Vitek 2 system were: C. albicans (93.3%), for C. glabrata (94.1%), C. tropicalis (83.3%), C. parapsilosis (75%) and 100% for C. guilliermondii and C. krusei.. fluconazole sensitivity of all isolates was 93.6%

Resumen Introducción. El exceso de adiposidad es considerado como el factor de riesgo más importante para la presión arterial alta (PAA) en niños y adolescentes. Objetivos. Explorar la asociación entre PAA y sobrepeso (SP) y obesidad abdominal (OA), mediada por condición física cardiorrespiratoria (CFC), y analizar el efecto combinado de la adiposidad excesiva y la CFC en la PAA en una muestra de escolares de Montería, Colombia.

Se evaluó la presión arterial, los indicadores antropométricos y la condición física; las mediciones fueron realizadas por personal capacitado mediante el uso de protocolos e instrumentos estandarizados. La asociación de PAA con condición física y adiposidad fue analizada a través de modelos de regresión logística. Resultados. Se encontró una asociación entre PAA y SP, OA y baja CFC. La inclusion de la CFC en el modelo no atenuó la asociación entre PAA y SP y entre PAA y OA. Los adolescentes con mayor adiposidad y baja CFC fueron más propensos a presentar PAA que aquellos con menor adiposidad y alta CFC. Además, se observó que la presencia de adiposidad excesiva y baja CFC aumenta el riesgo de desarrollar PAA. Conclusión. La PAA es una condición prevalente en niños y adolescentes de Montería, además se encontró una asociación estádisticamente significativa entre PAA y SP, OA, y baja CFC, por lo que es necesario que en el país se implementen estrategias que promuevan hábitos saludables en escolares y permitan reducir la tasa de incidencia de PAA en esta población.

Abstract Introduction: Excess adiposity is considered the most important risk factor for high blood pressure (HBP) in children and adolescents. Objectives: To explore the association between HBP and overweight (OW) and abdominal obesity (AO), mediated by cardiorespiratory fitness (CRF). To analyze the combined effect of excess adiposity and CRF on HBP among a sample of school-aged children from Montería, Colombia. Materials and methods: Cross-sectional study conducted in a sample of 546 adolescents aged between 11 and 18 years from 14 randomly selected schools in Montería. Blood pressure, anthropometric, and fitness measures were evaluated by trained personnel using standardized protocols and instrumentation. The association of HBP with fitness and fatness was analyzed using logistic regression models. Results: HBP was associated with OW, AO and low CRF. The inclusion of CRF in this model did not attenuate the association between HBP and OW and between HPB and AO. Adolescents with higher adiposity and low CRF were more likely to have HBP compared with those with lower adiposity and high CRF. Moreover, it was found that excess adiposity and low CRF had an additive effect on the risk for HBP among the sample. Conclusion: HBP is a prevalent condition in children and adolescents from Montería, Colombia. HBP is significantly associated with OW, AO, and low CRF; therefore, it is necessary to implement initiatives to promote healthy habits aimed at this population in order to reduce the incidence rate of HBP in Colombian adolescents.

Abstract Background: Alopecia areata is an autoimmune disease that produces non-scarring hair loss around the body. Gene variants of the cytotoxic T-lymphocyte antigen 4 (CTLA4) gene, a negative regulator of T-cell response, have been associated with a predisposition to autoimmune diseases in different populations; however, the involvement of these genetic variants in the development of AA is controversial. Objective: The present study evaluated the potential association of two CTLA4 gene variants with alopecia areata in a Mexican population. Methods: We genotyped +49AG (rs231775) and CT60 (rs3087243) variants in 50 AA patients and 100 healthy control participants through PCR-RFLP. Results: No statistical difference was observed for either of the gene variants regarding allele or genotype frequencies between AA patients and the controls when the parameters of family/personal history of autoimmune diseases or gender were considered (p > 0.05). Study limitations: Small sample size of patients and the data were obtained from Northeast Mexico population. Conclusion: The genetic variants rs231775 and rs3087243 of the CTLA4 gene are not a risk factor for the development of alopecia areata in the analyzed Mexican population.

ABSTRACT Intestinal malrotation is a congenital anomaly of intestinal rotation and fixation, diagnosed infrequently in adulthood. We report the presence of intestinal malrotation in a previously asymptomatic adult patient with changes in bowel habit in the last 6 months after a colonoscopy is performed with evidence of a polyp in the cecum, after resection presenting acute abdominal pain in the left iliac fossa that allows imaging to confirm the diagnostic.

RESUMEN La malrotación intestinal es una anomalía congénita de la rotación y fijación intestinal, diagnosticada de forma infrecuente en la edad adulta. Se presenta un caso de malrotación intestinal en un paciente adulto previamente asintomático con cambios en el hábito intestinal en los últimos 6 meses al que se le realiza una colonoscopia ambulatoria con la evidencia de un pólipo en el ciego, posterior a su resección presenta dolor abdominal agudo en fosa ilíaca izquierda que permite la realización de estudios imagenológicos que confirman el diagnóstico.

Resumen En ecología una de las preguntas más importantes es: ¿cuáles son los factores ambientales que explican la alta diversidad de especies de plantas en los bosques tropicales? En este trabajo, se estudiaron las comunidades de palmas y su relación con los nutrientes del suelo en dos localidades del Chocó biogeográfico. Específicamente, se investigó: (1) cómo varían los nutrientes del suelo entre las dos localidades; (2) cuál es la relación entre los nutrientes del suelo y la composición florística de palmas; (3) cuáles son los nutrientes más importantes que explican la variación en la composición florística de las comunidades de palmas; y (4) cómo varía la abundancia de las especies dominantes de sotobosque y de dosel a lo largo del gradiente de concentración de los nutrientes más importantes. Se realizaron 20 transectos de 500 x 5 m (5 ha), en los cuales se identificaron y contaron todos los individuos de palmas en sus diferentes estadios de crecimiento. Las muestras de suelo se tomaron en cada uno de los transectos a los 0 , 250 y 500 m. Los cationes (Al, Ca, Mg, K, P) se extrajeron con la técnica Mehlich-III y las concentraciones se analizaron con espectrometría de emisión con plasma de acoplamiento inductivo (ICP-OES). La concentración de macronutrientes se relacionó con la composición florística mediante el test de Mantel, el test parcial de Mantel, regresiones lineales y escalamiento multidimensional no métrico (NMDS). Se encontraron 9 158 individuos y 33 especies de palmas en las 5 ha cubiertas por los transectos. La composición florística presentó una correlación positiva y significativa con los nutrientes del suelo (rM = 0.63-0.69) y con la distancia geográfica entre los transectos (rM = 0.71-0.75), mientras que las variables edáficas mostraron una alta correlación con la distancia geográfica (rM = 0.72). Asimismo, se encontró una débil relación significativa entre la fertilidad del suelo y la abundancia de palmas de sotobosque, pero ninguna con las palmas del dosel. Nuestros resultados demuestran que los suelos juegan un papel importante en la composición de las comunidades de palmas a escalas locales en la región del Chocó, y que los suelos más pobres y ricos en fósforo presentan la mayor diversidad de palmas.

Abstract One of the most important questions in ecology is: which are the environmental factors that explain the high plant diversity of tropical forests? We studied the floristic composition of palm communities and their relationship to soil nutrients in two localities of the Chocó region to understand (1) how soil nutrients vary between the two localities; (2) what is the relationship between soil nutrients and palm floristic composition; (3) what are the most important nutrients that explain the variation in floristic composition of palm communities; and (4) how does the abundance of the most exuberant understory and canopy palm species vary along the concentration gradient of the most important nutrients? We established 20 transects (5 x 500 m) and identified all palm individuals of all growth stages. Soil samples were taken at each transect at the beginning, middle, and end. Macronutrients (Al, Ca, Mg, K, P) were extracted with the Mehlich-III technique and their concentrations were analyzed by inductively coupled plasma emission spectrometry (ICP-OES). We used Mantel test, partial Mantel tests, linear regressions, and non-metric multidimensional scaling to determine if the concentration of nutrients was related to the floristic composition. We found a total of 9 158 individuals and 33 species of palms in the 5 ha covered by our transects. Floristic composition had a positive and significant correlation with soil nutrients (rM = 0.63-0.69) and with geographical distance between transects (rM= 0.71-0.75), whereas the soil nutrients were highly correlated with geographical distance (rM = 0.72). We also found a small, yet significant, relationship between soil fertility and the abundance of understory palms, but no relationship with canopy palms. Our results demonstrate for the first time that soils play an important role in the composition of palm communities at local scales in the Chocó region, and that infertile and phosphorus-rich soils have the highest palm diversity.

It was synthesized nine polyoxygenated chalcones with a potential and safe use as antioxidant, antimicrobial and anti-inflammatory therapies. Chalcones obtained by Claisen-Schmidt condensation were studied as antioxidant, inhibitors of human 5-lipoxygenase, antifungal, antibacterial and antibiotic resistance modifiers. Two chalcones with catecholic moieties were able to strongly decrease the minimum inhibitory concentration (MIC) of methicillin against methicillin-resistant Staphylococcus aureus, increase the antiradical activity and significantly inhibit the human 5-lipoxygenase. Only one of these chalcones was active synergistically with methicillin. Chalcones with methoxyl substituents at different positions displayed the best activities against Cryptococcus neoformans. Only one chalcone showed good activity against the plant pathogenic bacteria Pseudomonas syringae whose half maximal inhibitory concentration (IC50) value (2.5 µg mL-1) was similar to that observed with the antibiotic streptomycin (2.9 µg mL-1). These simple chalcones have safe potential uses in antioxidant, antimicrobial and anti-inflammatory therapies.

Abstract: Background: Vitiligo is characterized by a lack of pigmentation in the skin. To date, there are no studies that analyze the changes in gene expression in the skin of vitiligo patients in response to narrow-band ultraviolet B (nb-UVB) phototherapy treatment. Objective: Explore the usefulness of new generation RNA sequencing in the identification of gene expression changes in the skin of vitiligo patients treated with nb-UVB phototherapy. Methods: Four skin biopsies (4mm in diameter) were collected from 45 Mexican vitiligo vulgaris patients, 2 specimens before and 2 after treatment with nb-UVB phototherapy, obtained from pigmented and non-pigmented tissue. RNA extracted from the biopsies was analyzed using the Illumina TruSeq Targeted RNA Expression protocol to study the expression of genes that participate in pathways of skin homeostasis. The 2 groups were compared using Student's t-test and the Mann-Whitney U-test. Results: The expression analysis identified differences in 12 genes included in this study after comparing the samples obtained before and after treatment: 5 genes involved in skin pigmentation, 2 genes involved in apoptosis, 2 genes involved in cell survival, 2 genes involved in oxidative stress responses and 1 gene involved in signal transduction mechanisms (p<0.05). Study limitations: The small size of skin biopsies limits the amount of RNA obtained, the number of genes to be analyzed and the use of conventional techniques such as RT-qPCR. Conclusion: We demonstrated usefulness of new generation RNA sequencing in the identification of gene expression changes, in addition to identifying new targets in the study of vitiligo.
