RESUMEN Antecedentes. El índice de calidad del agua (ICA) es una herramienta práctica y útil para estimar la calidad de los cuerpos de agua, este método se ha utilizado en muchos países. Objetivos. Evaluar la calidad del agua de la cuenca del río Ayuquila-Armería, con base en dos categorías de posible uso del recurso agua, uso en riego agrícola, protección de la vida acuática y uso potable. Métodos. Se realizó el análisis de variables físicas y químicas, análisis de metales pesados y nutrientes y la caracterización de aniones y cationes; además se complementaron las variables con la utilización de un índice de integridad biótica basado en familias de macroinvertebrados acuáticos, para estimar la contaminación orgánica y la determinación de coliformes fecales, en los cuarenta sitios de muestreo a lo largo de la parte alta, media y baja de la cuenca. Resultados. De los cuarenta sitios, la calidad del agua para uso en riego agrícola presento rangos del ICA de condiciones regulares (35%), buenas (27.5%) y excelentes (37.5 %). En cuanto a la comparación realizada para la calidad del agua para protección de la vida acuática y uso potable, se encontró que ocho sitios (44.4%) presenta condiciones de mala calidad, otros ocho sitios (44.4%) presentan buena calidad y solo dos sitios (11.11%) una condición de calidad excelente. Conclusiones. Para el uso de agua en riego agrícola no se encuentra ningún sitio que presente mala calidad del recurso, además mediante la utilización de diferentes parámetros relacionados con la agricultura se puede asegurar que no existe riesgo de pérdida o daño en cultivos por utilizar el agua para irrigación. Para el caso de la calidad del agua en cuanto a la protección de la vida acuática y uso potable, en general la cuenca presenta malas condiciones. En este sentido los organismos acuáticos están sufriendo afectaciones tanto en su hábitat como en las condiciones fisicoquímicas que pueden menguar sus poblaciones, por otra parte, las comunidades humanas cercanas a los cauces hídricos serán más susceptibles a tener problemas relacionados con la salud.

ABSTRACT Background. The water quality index (ICA) is a practical and useful tool to estimate the quality of water bodies, this method has been used in many countries. Goals. Evaluate the water quality of the Ayuquila-Armería river basin, based on two categories of possible use of the water resource, use in agricultural irrigation, protection of aquatic life and drinking use. Methods. The analysis of physical and chemical variables, analysis of heavy metals and nutrients and the characterization of anions and cations were carried out; In addition, the variables were complemented with the use of a biotic integrity index based on families of aquatic macroinvertebrates, to estimate organic contamination and the determination of fecal coliforms, in the forty sampling sites along the upper, middle, and lower part. of the basin. Results. Of the forty sites, the quality of the water for use in agricultural irrigation presented ICA ranges of regular (35%), good (27.5%) and excellent (37.5%) conditions. Regarding the comparison made for the quality of water for the protection of aquatic life and drinking use, it was found that eight sites (44.4%) present poor-quality conditions, another eight sites (44.4%) present good quality and only two sites (11.11%) an excellent quality condition. Conclusions. For the use of water in agricultural irrigation, there is no site that presents poor quality of the resource, in addition, by using different parameters related to agriculture, it can be ensured that there is no risk of loss or damage to crops by using water for irrigation. In the case of water quality in terms of the protection of aquatic life and potable use, in general the basin presents poor conditions. In this sense, aquatic organisms are suffering effects both in their habitat and in the physicochemical conditions that can decrease their populations, on the other hand, human communities near watercourses will be more susceptible to health-related problems.

ABSTRACT Death processes have been progressively transferred to hospital spaces due to biomedicalization and the use of technologies, generating important challenges for healthcare systems. The COVID-19 pandemic exposed the lack of unified criteria and principles for a dignified death in the hospital. This study corresponds to a narrative review using Higgins & Green's methodological framework as a reference. A systematized search was carried out with the question: What are the elements considered in the decision-making of hospital teams regarding access and use of life support technology and dying processes in adult critically ill patients? The searches conducted during October 2022 in MEDLINE/PubMed, Scopus, Science Direct, CINAHL, Biblioteca Virtual en Salud (BVS), Cochrane Library, and Scielo identified 1499 records for screening, and 148 were retrieved for full-text review. Eighty-four articles were included in the review, identifying seven categories. The evidence shows variability in decision-making associated with the clinical status of the patient, the criteria of the medical professional, added to structural elements of the health system and political-legal aspects. The literature recommends reflexive, dynamic, flexible, and individualized decision-making processes that consider the patient's preferences, clinical judgment, prognosis, and available resources. Communication, advance care planning, interdisciplinary discussions, external consultations, and the involvement of ethical committees are crucial throughout the process.

RESUMEN Los procesos de muerte han sido transferidos progresivamente a los espacios hospitalarios producto de la biomedicalización y el uso de tecnologías, generando importantes desafíos para los sistemas sanitarios. La pandemia por COVID-19 dejo al descubierto la falta de criterios unificados, y de principios para una muerte digna en el hospital. Este estudio corresponde a una revisión narrativa que utiliza como referencia el marco metodológico de Higgins & Green. Se realizó una búsqueda sistematizada con la pregunta: ¿Cuáles son los elementos considerados en la toma de decisiones de equipos hospitalarios respecto al acceso y uso de la tecnología de soporte vital y procesos de muerte en pacientes críticos adultos? Las búsquedas realizadas durante octubre de 2022 en MEDLINE/PubMed, Scopus, Science direct, CINAHL, Biblioteca Virtual en Salud (BVS), Cochrane Library y Scielo, identicaron1.499 registros para screening, 148 fueron recuperados para revisión en texto completo. 84 artículos fueron incluidos en la revisión, identificando siete categorías. La evidencia muestra variabilidad en la toma de decisiones asociada al estado clínico del paciente, al criterio del profesional médico, sumado a elementos estructurales del sistema sanitario y los aspectos político-legales. La literatura recomienda procesos de toma de decisiones reflexivos, dinámicos, flexibles e individualizados que consideren las preferencias del paciente, el juicio clínico, el pronóstico y los recursos disponibles. La comunicación, la planificación anticipada de los cuidados, los debates interdisciplinarios, las consultas externas y la participación de comités éticos son cruciales durante todo el proceso.

Resumen Se ha mostrado experimentalmente que cuando se deposita una gota en el centro de un sustrato con un gradiente axial de temperatura (más caliente en el centro), por efectos termocapilares se genera un flujo hacia afuera de modo que la gota evoluciona hacia un anillo cuyo radio crece con el tiempo. Al alcanzar un radio crítico, la línea de contacto se inestabiliza, mostrando suaves ondulaciones cuyas amplitudes crecen con el tiempo. Utilizando la aproximación de lubricación y adoptando adecuadas variables adimensionales, se obtiene una ecuación diferencial libre de parámetros que gobierna este tipo de flujo termocapilar. En este trabajo se presentan soluciones numéricas de dicha ecuación para estudiar en particular la etapa inestable. Se comparan los resultados experimentales con los obtenidos con las soluciones numéricas.

Abstrac It has been shown experimentally that when a drop is deposited at the center of a substrate with an axial temperature gradient (hotter in the center), thermocapillarity effects makes an outward flow to appear so that the drop evolves towards a ring whose radius increases with time. Upon reaching a critical radius, the contact line becomes unstable, showing gentle undulations whose amplitudes grow with time. Using the lubrication approximation and adopting appropriate dimensionless variables, a parameter-free differential equation is obtained that governs this type of thermocapillary flow. Numerical solutions of this equation are presented to study the unstable stage. Experimental results are compared with those obtained from the numerical solutions.

Abstract Background: Magnetic Resonance Imaging (MRI) of the prostate is a key diagnostic tool for identifying prostate carcinoma. The Prostate Imaging-Reporting and Data System (PI-RADS) scale is the standard system for interpreting these images. Standardizing and evaluating this scale is crucial for ensuring consistent and reproducible results. Objective: This study aims to assess both the interobserver and intraobserver agreement of the PI-RADS version 2.1. Material and methods: In this retrospective observational study, 129 prostate MRI scans from patients with suspected prostate cancer were evaluated. Three radiologists, each with different levels of experience, analyzed these scans at two separate times using the PI-RADS 2.1 scoring system. Both intraobserver and interobserver agreements were measured. Results: The study found substantial interobserver agreement (kappa > 0.6) across all categories, with category 5 showing the highest level of agreement. Intraobserver reproducibility was also high, with the highest kappa value reaching 0.856. Further analysis based on the radiologists’ years of experience revealed significant interobserver agreement in all instances. Conclusions: The PI-RADS 2.1 classification system demonstrates high reproducibility across different categories, particularly for lesions more likely to be clinically significant cancers. This underscores its reliability in varied diagnostic scenarios.

Resumen Antecedentes: La resonancia magnética (RM) de próstata es uno de los métodos diagnósticos para la identificación del carcinoma de próstata. La escala PI-RADS (Prostate Imaging and Reporting Data System) es el sistema usado para la interpretación de estas imágenes. Es importante, para su reproducibilidad, la estandarización y la evaluación de dicha escala. Objetivo: Determinar la concordancia inter- e intraobservador de la versión 2.1 del PI-RADS. Material y métodos: Estudio observacional retrospectivo, evaluando 129 RM de pacientes con sospecha de cáncer de próstata por tres radiólogos con diferentes años de experiencia y en dos momentos del tiempo, usando el puntaje PI-RADS 2.1. Se evaluó la concordancia intra- e interobservador. Resultados: La concordancia interobservador fue sustancial (kappa > 0,6) en todos los observadores, siendo la categoría 5 la de mayor acuerdo interobservador. Se observó una alta reproducibilidad intraobservardor, con la mayor kappa siendo de 0,856. Cuando se realizó el análisis según años de experiencia de los radiólogos, la concordancia interobservador fue significativa en todos los casos. Conclusiones: El sistema de clasificación PI-RADS 2.1 es reproducible para las diferentes categorías y aumenta la concordancia cuando se trata de lesiones con mayor probabilidad de cáncer clínicamente significativo.

RESUMEN Introducción: El suicidio es un complejo problema de salud pública global. La guía colombiana de práctica clínica es un insumo relevante para su prevención, diagnóstico y tratamiento. El objetivo es evaluar la calidad metodológica, la credibilidad y la aplicabilidad de la guía de práctica clínica colombiana sobre la conducta suicida. Métodos: Un grupo académico de 12 evaluadores se estandarizó para la valoración de la guía y sus recomendaciones mediante los instrumentos AGREE-II y AGREE-REX. Las valoraciones se dieron en el intervalo de 0,0-1,0, con 0,7 como punto de corte para apropiada calidad. Resultados: La valoración global del AGREE-II fue >0,7 en las dimensiones «alcance y objetivo» (0,86), «claridad de la presentación» (0,89), «aplicabilidad» (0,73) e «independencia editorial» (0,89). Los menores puntajes fueron para «participación de los implicados» (0,67) y «rigor en la elaboración» (0,69). Con el AGREE-REX los resultados en todas las dimensiones estuvieron por debajo de 0,70, lo cual indica menores calidad e idoneidad de uso. Conclusiones: El proceso de adopción de la guía colombiana sobre conducta suicida fue un proceso riguroso en lo metodológico, en tanto que las recomendaciones de práctica se valoraron como de baja aplicabilidad por el escaso sustento en evidencia local. Se requiere fortalecer la generación y la síntesis de evidencia en el país para dar más soporte y aplicabilidad a las recomendaciones de práctica.

ABSTRACT Introduction: Suicide is a complex, global public health problem. The Colombian clinical practice guideline provides relevant input for its prevention, diagnosis and treatment. The objective was to evaluate the methodological quality, credibility and applicability of the Colombian clinical practice guideline for suicidal behaviour. Methods: An academic group of 12 evaluators was established to assess the guide and its recommendations in a standardised way, using the AGREE-II and AGREE-REX instruments. The evaluations were given in the range of 0.0-1.0 with 0.7 as a cut-off point for appropriate quality. Results: The global assessment of the AGREE-II was greater than 0.7 in the dimensions: "scope and objective" (0.86), "clarity of presentation" (0.89), "applicability" (0.73) and "editorial independence" (0.89). The lowest scores were for "participation of those involved" (0.67) and "rigour in preparation" (0.69). With the AGREE-REX, the results in all dimensions were below 0.70, which indicates lower quality and suitability for use. Conclusions: The adoption process of the Colombian guideline for suicidal behaviour was a rigorous methodological process, while the practice recommendations were valued as of low applicability due to low support in local evidence. It is necessary to strengthen the genera-tion and synthesis of evidence at the national level to give greater support and applicability to the practice recommendations.

ABSTRACT Introduction: With the introduction of minimally invasive cardiac surgery, more commonly cases of lung herniation are starting to appear. Acquired lung hernias are classified as postoperative, traumatic, pathologic, and spontaneous. Up to 83% of lung hernias are intercostal. Herein, we describe patients presenting with intercostal lung hernias following minimally invasive cardiac surgery at a single center in Medellín, Colombia. Methods: We conducted a retrospective search of all patients presenting with intercostal lung hernias secondary to minimally invasive cardiac surgery at our clinic in Medellín since the beginning of our program, from 2010 to 2022. Mini-sternotomies were excluded from our study. We reviewed the incision type and other possible factors leading to intercostal lung hernia development. We also describe the approach taken for these patients. Results: From 2010 up until 2022, 803 adult patients underwent minimally invasive cardiac surgeries through a mini-thoracotomy. At the time of data retrieval, nine patients presented with intercostal lung hernias at the previous incision site. Five hernias (55%) were from right 2nd intercostal parasternal mini-thoracotomies for aortic valve surgeries. Four hernias (45%) were from right 4th intercostal lateral mini-thoracotomies for mitral valve surgeries. Our preferred repair technique is a video-assisted thoracoscopic mesh approach. Conclusion: Minimally invasive cardiac surgical approaches are becoming more routine. Proper wound closure is critical in preventing lung hernias. Additionally, timely diagnosis and opportune hernia surgery using video-assisted thoracoscopic mesh repair can prevent further complications.

This work studied the cyclic spherical contact behavior of plasma nitrided (N) and nitrocarburized (NC) AISI 321 steel. The temperature and exposition time were 400 and 500 °C for 6 h in each treatment. A superficial hardness between ~10 (NC 400 °C) and ~17 GPa (NC 500 °C) was found by instrumented indentations; moreover, plastic and total work of indentation were analyzed. In cyclic spherical contact assessment, a critical load was first determined by applying tests between 100 and 1000 N. Next, cyclic tests were conducted with three subcritical loads (120, 150, and 180 N) and up to 105 cycles. A detrimental effect of treatment temperature was observed, 500 °C treatments presented worse failures than 400 °C, which is explained by the decomposition of expanded austenite. Between 400 °C treatments, nitrocarburizing presented a better performance, its higher plastic work of indentation is associated with a better energy absorption capacity.

ABSTRACT Bycatch species are as important as target species in the challenge of comprehensive fishery management. This is especially the case for vulnerable species such as elasmobranchs in offshore areas of the Colombian Pacific Ocean (CPO), for which information is scarce and long-term databases are used. Therefore, this study aimed to characterize the bycatch in tuna purse-seine fishery with an elasmobranch species approach using fishery data from 2000 to 2019. A total of 59 bycatch species were identified, including 27 bony fishes, 22 elasmobranchs, two mollusks, four sea turtles, and four dolphins. The total bycatch percentage was 20.8%, with elasmobranchs accounting for less than 5%. Fish aggregating devices (FADs) and class 6 vessels recorded the highest percentage of bycatch. Bony fish bycatch was mainly obtained from the border of Ecuador until 4° N across the CPO. Elasmobranchs were captured throughout the CPO, showing differences by vessel class and fishing method. The silky shark Carcharhinus falciformis was the most caught species. Elasmobranch spatial abundance and capture hotspots showed the highest values towards the northern coast, in offshore areas of Gorgona Island, southwards in offshore areas, and around Malpelo Island. FADs captured the highest number of bycatch species compared with other fishing methods, such as Tuna Associated with Dolphins (DEL), Natural Floating Objects (NAT), and Tuna not Associated (NoAs). Management recommendations for bycatch species in this fishery are provided in the CPO. management CPO , (CPO) longterm long term used Therefore purseseine purse seine 200 2019 5 identified 2 fishes mollusks turtles dolphins 208 20 8 20.8% 5% (FADs 4 method coast Island methods DEL, DEL (DEL) NAT, NAT (NAT) NoAs.

ABSTRACT Objectives. To assess the frequency of symptoms in patients with Oropouche fever and compare them with those observed in patients with dengue and other arboviral diseases. Methods. A systematic review was conducted following the MOOSE and PRISMA reporting guidelines. The review included studies on acute clinical manifestations in patients with Oropouche fever. Searches were conducted in PubMed, Virtual Health Library, Cochrane Library, and Google Scholar up to September 2024. The symptoms of Oropouche fever were compared to those of dengue and other arboviral diseases. Certainty of evidence was assessed using the GRADE approach. Results. A total of 23 studies covering 3648 patients with Oropouche fever were included. The most frequent symptoms in patients with Oropouche virus infection were fever (97%) and headache (86%). There was no difference in frequency of fever or headache between patients with Oropouche and dengue. However, odynophagia (28%) and abdominal pain (15%) were more frequent in Oropouche than in dengue, with odds ratios (ORs) of 3.20 and 2.50, respectively. Myalgia (69%) and arthralgia (57%) were less frequent in Oropouche fever than in dengue. Conclusions. Fever and headache are common in Oropouche virus infection, but do not help discriminate it from dengue. However, odynophagia and abdominal pain are more frequent in patients with Oropouche fever, while myalgia, arthralgia, and rash are more prevalent in dengue. These findings may aid in differential diagnosis in areas of arboviral co-circulation. Further studies on the recurrence and duration of symptoms are needed to improve diagnostic strategies.

RESUMO Objetivos. Avaliar a frequência de sintomas em pacientes com febre do Oropouche e compará-los aos observados na dengue e em outras arboviroses. Métodos. Revisão sistemática, com base nas diretrizes MOOSE e PRISMA, incluindo estudos sobre manifestações clínicas agudas em pacientes com febre do Oropouche. A busca incluiu as bases de dados PubMed, Biblioteca Virtual em Saúde, Cochrane Library e Google Scholar e recuperou documentos publicados até setembro de 2024. Os sintomas da febre do Oropouche foram comparados com os da dengue e de outras arboviroses, e a certeza foi avaliada usando a abordagem GRADE. Resultados. Foram incluídos 23 estudos com 3 648 pacientes com a febre do Oropouche. Os sintomas mais frequentes nesses pacientes foram febre (97%) e cefaleia (86%). Não houve diferença na frequência de febre e cefaleia entre os pacientes com febre do Oropouche e com dengue. No entanto, a odinofagia (28%) e a dor abdominal (15%) foram mais frequentes na febre do Oropouche que na dengue (razões de chances de 3,20 e 2,50, respectivamente). Mialgias (69%) e artralgias (57%) foram menos frequentes em pacientes com febre do Oropouche que em pacientes com dengue. Conclusões. Febre e cefaleia são comuns na febre de Oropouche, mas não ajudam a diferenciá-la da dengue. Por outro lado, odinofagia e dor abdominal são mais frequentes nos pacientes com febre do Oropouche, ao passo que mialgia, artralgia e exantema são mais prevalentes na dengue. Esses achados podem ajudar no diagnóstico diferencial em áreas de cocirculação de arbovírus. São necessários mais estudos sobre a recorrência e a duração dos sintomas para aprimorar as estratégias de diagnóstico.

ABSTRACT Objective. To evaluate the influence of lutropin alfa (recombinant human LH, r-hLH) administered at 12 and 24 h post progesterone device withdrawal (CIDR) on the response of hours to onset of estrus (OE), ovulatory rate (OR), unfertilized oocytes (UNO), transferable embryos (TE), quality 1 embryos (Q1E) and plasma LH levels, in a pFSH-based superovulation protocol in Pelibuey sheep. Materials and methods. Eighteen Pelibuey sheep were used and randomly distributed into three groups (n=6): T1 (200 mg FSHp-Folltropin®); T2 (200 mg FSHp + 75 IU r-hLH at 12 h post CIDR withdrawal) and T3 (200 mg pFSH + 75 IU r-hLH at 24 h post CIDR withdrawal). Results. No significant differences were found between OE and OR. UNO was higher (p<0.05) in T2 (5.0±2.3) compared to T1 (0.8±0.6) and T3 (1.3±0.7). The number of Q1E was higher (p<0.05) in T3 (3.1±1.1) compared to T1 (1.1±0.3) and T2 (0.6±0.5) and for TE was higher (p<0.05) for T3 (6.6±0.9) relative to T2 (2.0±1) and T1 (4.0±0.6). Conclusions. The application of r-hLH 24 h after removal of CIDR increases plasma LH levels, in effect, decreasing the amount of UNO, improving the quantity and quality of TE in Pelibuey sheep.

Abstract Introduction: In Mexico, cardiac rehabilitation (CR) as an interdisciplinary intervention with therapeutic impact in patients with heart disease is growing. There is the need to know actual conditions of CR in our country. Objectives: The objective of this National Registry is to follow-up those existing and new CR units in Mexico through the comparison between the two previous registries, RENAPREC-2009 and RENAPREC II-2015 studies. This is a descriptive study focused on diverse CR activities such as assistance training, and certification of health professionals, barriers, reference, population attended, interdisciplinarity, permanence over time, growth prospects, regulations, post-pandemic condition, integrative characteristics, and scientific research. Results: Data were collected from 45 CR centers in the 32 states, 75.5% are private practice units, 67% are new, 33% were part of RENAPREC II-2015, and 17 have continued since 2009. With a better distribution of CR units along the territory, the median reference of candidates for CR programs is 9% with a significant reduction into tiempo of enrollment to Phase II admission (19 ± 11 days). Regarding to previous registries, the coverance of Phases I, II, and III is 71%, 100%, and 93%, respectively; and a coverance increases in evaluation, risk stratification, and prescription, more comprehensive attendance and prevention strategies. Conclusions: CR in Mexico has grown in the past 7 years. Even there is still low reference and heterogeneity in specific processes, there are strengths such as interdisciplinarity, scientific professionalization of specialists, national diversification, and an official society that are consolidated over time.

RESUMO Geralmente, a classificação taxonômica das sementes de cacau foi feita pela relação teobromina/cafeína por cromatografia líquida de alto desempenho (HPLC). No entanto, esta técnica envolve determinações laboriosas e demoradas; assim, a espectroscopia atenuada de infravermelho de reflexão total (ATR-FTIR) é uma ferramenta valiosa, eficaz e rápida para analisar a composição química dos produtos alimentares. Neste estudo, o objetivo era examinar o potencial da ATR-FTIR combinado com ferramentas quimiométricas como a análise de componentes principais (PCA), a análise discriminante linear (LDA), e a análise menos regressiva quadrada parcial (PLS-DA) examinada para a discriminação entre as variedades de cacau Trinitario e Forastero definidas pelas medições de teobromina e cafeína via HPLC. As variedades de cacau foram avaliadas pela análise por HPLC de 36 amostras de grãos de cacau secos para a relação teobromina/cafeína. Além disso, os espectros ATR-FTIR foram analisados em regiões de infravermelhos médios (MIR), e os sinais associados à teobromina e à cafeína foram identificados e analisados através dos modelos LDA e PLS-DA. Os modelos LDA e PLS-DA proporcionaram uma discriminação satisfatória do cacau, fornecendo valores de capacidade de previsão global de 98.2 ± 1.8% e 96.1 ± 2.4%, respectivamente. Os resultados mostram o potencial da técnica de espectroscopia ATR-FTIR para uma diferenciação fiável, rápida e fácil das amêndoas de cacau secas. Geralmente teobrominacafeína .

ABSTRACT Generally, the taxonomic classification of cocoa beans is based on the theobromine/caffeine ratio determined using high-performance liquid chromatography (HPLC). However, this technique involves laborious and time-consuming calculations. Attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy is a valuable, effective, and rapid tool for analyzing the chemical composition of food products. The objective of this study was to examine the potential of ATR-FTIR combined with chemometric tools such as principal component analysis (PCA), linear discriminant analysis (LDA), and partial least squares regression-discriminant analysis (PLS-DA) to discriminate between the Trinitario and Forastero dry bean cocoa varieties defined by theobromine and caffeine measurements via HPLC. The cocoa varieties were evaluated using HPLC analysis of 36 dry cocoa bean samples to determine the theobromine/caffeine ratio. Moreover, ATR-FTIR spectra were analyzed in the mid-infrared (MIR) region, and signals associated with theobromine and caffeine were identified and analyzed using the LDA and PLS-DA models. The LDA and PLS-DA models allowed the satisfactory differentiation between cocoa varieties, providing overall prediction capacity values of 98.2 ± 1.8% and 96.1 ± 2.4%, respectively. The results show the potential of ATR-FTIR spectroscopy for the reliable, fast, and easy differentiation of dried cocoa beans. Generally theobrominecaffeine highperformance high performance .

Abstract Introduction: Pregnancy represents a period of increased demand for thyroid hormones. Thyroid function evaluation is indicated during preconception/pregnancy, particularly if there is previous thyroid pathology or residence in a place with iodine deficiency. Iodine supplementation is safe in the presence of a normal value of thyroid stimulating hormone (TSH) and in the absence of thyroid pathology. Moreover, this evaluation allows early detection of thyroid dysfunction, minimizing the clinical risk in pregnancy. The aim of this study is to evaluate the performance in primary care regarding the evaluation of thyroid function, iodine supplementation and approach to thyroid pathology in pregnancy. Material and Methods: This study was analytical, observational and cross-sectional. The sample consists of pregnant women followed in four primary health care units, whose children were born between February 2019 and January 2020. Results: Of the 264 pregnant women included, 34.8% had a preconception consultation. A percentage of 90.9% of the pregnant women had no history of thyroid pathology. The TSH was measured in 49.6% and it was prescribed iodine supplementation in 89.2%. Three cases of hypothyroidism and one of hyperthyroidism were diagnosed. Most of the pregnant women with previous pathology was referred to the hospital, except for one woman with goiter. Conclusion: In primary care the approach to thyroid dysfuntion should be systematized and standardized given the particularities of, namely, iodine supplementation and hospital referral. Pre-conception consultation is essential in cases of previous known pathology. It would be desirable to have an updated national guideline to standardize procedures in this area.

Resumo Introdução: A gravidez representa um período de maior necessidade de hormonas tiroideias. A avaliação da função tiroideia está indicada na pré-conceção/gravidez, nomeadamente se houver patologia prévia da tiroide ou residência em local com défice de iodo. Na ausência de patologia tiroideia e havendo um valor normal de hormona tiroestimulante (TSH), é seguro iniciar suplementação com iodo. Além disso, esta avaliação permite deteção precoce de disfunção tiroideia, minimizando o risco clínico na gravidez. O objetivo deste trabalho é avaliar a atuação nos cuidados primários, relativa à avaliação da função tiroideia, à suplementação com iodo e abordagem de patologia da tiroide na gravidez. Material e Métodos: Estudo analítico, observacional e transversal. A amostra é constituída por grávidas seguidas em consulta de saúde materna em quatro Unidades de Saúde Familiar, cujos filhos nasceram entre fevereiro/2019 e janeiro/2020. Resultados: Das 264 grávidas incluídas, verificamos que 34,8% realizou consulta pré-concecional. Na amostra estudada, 90,9% das gestantes não apresentavam antecedentes de patologia tiroideia, tendo sido doseada a TSH em 49,6% e instituída suplementação com iodo em 89,2%. Foram diagnosticados três hipotiroidismos e um hipertiroidismo. As grávidas com patologia prévia foram referenciadas à consulta hospitalar, à exceção de uma mulher com bócio. Conclusão: A avaliação da disfunção tiroideia deve ser sistematizada na prática clínica pelas particularidades na sua abordagem, nomeadamente na suplementação de iodo e na referenciação hospitalar. A consulta de pré-conceção é essencial nos casos de patologia prévia. Seria desejável uma norma atualizada e que uniformizasse procedimentos nesta área.

Abstract The treatment of ocular tuberculosis (TB) remains controversial worldwide. The development of guidelines for ocular TB can facilitate the approach and management of these patients. These guidelines should be developed regionally, considering the local TB epidemiology. The objectives of this consensus are: to initiate an interdisciplinary discussion about the epidemiology, pathophysiology, clinical presentation, diagnosis, workup and treatment of patients with ocular TB, to establish a treatment algorithm and define which patients should be treated in Chile and how and, to analyze and discuss the published data regarding chemoprophylaxis for patients with latent TB who need to start immunosuppressive treatment due to inflammatory ocular conditions.

Resumen Introducción: El tratamiento de la tuberculosis (TB) ocular es un tema que genera controversia en el mundo. Para el correcto manejo de estos pacientes, es necesario el desarrollo de guías que consideren la epidemiología de la TB ocular en cada nación. El objetivo de este consenso fue discutir de forma interdisciplinaria la epidemiología, fisiopatología, clínica, diagnóstico, estudio y tratamiento de los pacientes con TB ocular, para establecer un algoritmo de tratamiento y proponer qué pacientes deben ser tratados en Chile y con qué tratamiento. Además, se establecieron acuerdos para efectuar quimioprofilaxis de los pacientes con TB latente que tienen indicación de tratamiento inmunosupresor por enfermedades inflamatorias oculares.

Resumen: Esta investigación tiene como objetivo realizar un análisis comparativo del crecimiento y cobertura del sistema de transporte público colectivo urbano de la ciudad de Manizales (Colombia) en los años 2010, 2015 y 2021. Se aplican modelos geoestadísticos como base metodológica, complementados con análisis de cobertura y cambio relativo de la oferta. Los resultados muestran que la valoración de accesibilidad tiene un incremento en tiempo de viaje entre los años 2010 y 2015, evidenciando un estancamiento en la expansión del sistema de transporte. Se observa un salto importante en la cobertura de transporte público entre el 2015 y 2021, este salto se podría argumentar por las intervenciones viales generadas en la ciudad. Se concluye que las dinámicas de cobertura y acceso ofertadas por un sistema de transporte público colectivo urbano pueden verse afectadas por las dinámicas de crecimiento urbano si no se realizan intervenciones sustanciales y pertinentes.

Abstract: The primary goal of this research study is to perform a comparative analysis of the growth and coverage of the urban public transport system in the city of Manizales (Colombia) between the years 2010, 2015, and 2021. Geostatistical models are applied as a methodological basis, complemented with coverage and supply change analyses. The results show an increase in travel time between 2010 and 2015, suggesting stagnation in the expansion of the transportation system. There is a significant leap in public transport coverage between 2015 and 2021, which may be explained by transport infrastructure improvements in the city. It is concluded that the dynamics of coverage and access offered by an urban public transport system may be affected by the dynamics of urban growth if substantial and relevant interventions are not made.
