Los resultados sugieren que las emociones de los colombianos hacia el presidente de la Republica cambian de manera significativa ante los decretos y/o decisiones públicas establecidas.

Abstract The participation of social media users in the political control of the public management of the President of Colombia due to regulatory decisions related to the arrival of COVID-19 has generated different emotional reactions. This research analyzes the citizens' feelings on Facebook regarding the management of the president of Colombia during pandemic times. 12.474 comments are extracted from the Colombia Presidency's official fan page, through data mining. Then a Machine Learning model is applied to classify the underlying sentiments in the data set. The results suggest that the Colombians' emotions towards the president of the Republic change significantly before the decrees and/or established public decisions.

ABSTRACT Both systemic lupus erythematosus and antiphospholipid syndrome are autoimmune diseases with thromboembolic potential, especially due to the presence of thrombogenic antibodies. The lung is a common place where a thrombus usually settles and generates a thromboembolism, sometimes with subsequent infarction and cavitation. There are few studies reporting cavitary pulmonary infarction in a patient with lupus associated with antiphospholipid syndrome. We present the case of a 24-year-old woman with general symptoms and cavitated right lung lesion. She was initially treated as tuberculous or fungal infection. Laboratory tests and images guided and diagnosed lupus associated with antiphospholipid syndrome, complicated by pulmonary thromboembolism that later became cavitated. The patient improved considerably with anticoagulants, corticosteroids, and cyclophosphamide.

RESUMEN Tanto lupus eritematoso sistémico como el síndrome antifosfolípido son enfermedades autoinmunes con potencial tromboembólico, sobre todo por la presencia de anticuerpos trombogénicos. El pulmón es un lugar común donde suele asentarse un trombo y generar una tromboembolia, a veces con posterior infarto y cavitación. Existen pocos estudios que informen un infarto pulmonar cavitado en un paciente con lupus asociado a síndrome antifosfolípido. Presentamos el caso de una mujer de 24 años con síntomas generales y lesión pulmonar derecha cavitada. Fue tratada inicialmente como infección tuberculosa o fúngica. La analítica y las imágenes orientaron y diagnosticaron lupus asociado a síndrome antifosfolípido, complicado con tromboembolismo pulmonar que luego pasó a cavitarse. La paciente mejoró considerablemente con anticoagulantes, corticoides y ciclofosfamida.

RESUMO O objetivo deste artigo é apresentar o caso de uma égua crioula colombiana de 15 anos com histórico de abortos e não obtenção de embrião, onde foi realizada avaliação do sistema genital externo e interno, ultrassonografia, citologia, cultura e biópsia endometrial realizados como métodos diagnósticos.; que relataram endometrite crônica de classificação II B, associada a edema tipo 4, estabelecendo prognóstico reservado para reprodução, após constatação de endometrite fúngica. O tratamento consistiu no uso de complexos vitaminicos, medicamentos biorreguladores, antifúngicos e antibióticos, nutracêuticos, minerais e lavagens intrauterinas. Após a medicação e três intervalos ovulatórios consecutivos, quatro embriões foram recuperados e transferidos com sucesso, dos quais três chegaram a termo, demonstrando assim a recuperação da função endometrial, graças à identificação dos microorganismos envolvidos e ao estabelecimento de terapia adequada. A endometrite é definida como a inflamação do endométrio, sendo considerada uma das principais causas de sub e infertilidade na égua, que geram perdas econômicas significativas, com incidência de 10 a 15 %. Existem diferentes etiologias, destacando-se a má conformação do perineo, útero abdominal, perda da atividade miometrial, número de montas, fatores moleculares e genéticos, além da presença de bactérias e fungos.

ABSTRACT The objective of this article is to present the case of a 15-year-old Colombian criollo mare with a history of abortions and no embryo obtaining, where the evaluation of the external and internal genital system, ultrasonography, cytology, culture and endometrial biopsy were performed as diagnostic methods; which reported chronic endometritis of classification II B, associated with type 4 edema, and establishing a reserved prognosis for reproduction, after verifying fungal endometritis. The treatment consisted of the use of vitamin complexes, bioregulatory medicine, antifungal and antibiotic therapy, nutraceuticals, minerals, and intrauterine washings. After the medication and three consecutive ovulatory intervals, four embryos were successfully recovered and transferred, of which three reached term, thus demonstrating the recovery of endometrial function, thanks to the identification of the microorganisms involved and the establishment of adequate therapy. And complemented. Endometritis is defined as inflammation of the endometrium, and is considered one of the main causes of sub and infertility in the mare, which generate significant economic losses, with an incidence of 10 to 15 %. There are different etiologies, highlighting the malconformation of the perineum, abdominal uterus, loss of myometrial activity, number of mounts, molecular and genetic factors, and the presence of bacteria and fungi.

ABSTRACT Background: Intersectoral health promotion initiatives in Chile to address obesity and non- communicable diseases have had a long history in Chile, but also a high degree of changes in their design, implementation, and financing. Aim: To analyze the “Choose a Healthy Lifestyle” enacted by Law 20,670 under Sabatier's “Advocacy Coalition Framework” (ACF), addressing the political discussion and its execution in the subsequent governing coalitions (2011-2022). Material and Methods: The ACF components are the following: external events, coalitions, policy subsystem (health promotion), and policy brokers. Policy change and learning occurs when a certain level of conflict exists between coalitions. We carried out a bibliographic and literature review, including history of the Law and notes in the media. Results: We identified two coalitions. The first is pro-individual freedom and aims to solve the problem with education and health promotion. The second one defines the problem as structural and related to social determinants and health inequity. The first coalition launched the “Choose Healthy Liferstyle” program in 2011 when they were in executive power. After criticism from the opposition and the participation of policy brokers, the Program was institutionalized with an intersectoral vision. The lack of permanent financing affected the continuity of the policy, especially after a change in the governing coalition. Conclusions: Law 20,670 falls within the ACF. However, policy learning slowed down because the problem involved social aspects, conflict between deep beliefs of both coalitions, and lack of permanent funding, thus affecting the continuity of the policy.

Antecedentes: Las iniciativas intersectoriales de promoción de salud en Chile han tenido una larga historia en el país, pero también un alto grado de cambios en su diseño, implementación y financiamiento. Objetivos: Analizar el “Sistema Elige Vivir Sano” (Ley 20.670) bajo el marco de “Coaliciones de Causa” (ACF), abordando la discusión política y su ejecución durante cambios de coaliciones gobernantes (2011-2022). Material y Métodos: Los componentes de ACF incluyen eventos externos, coaliciones, subsistema de políticas (promoción de salud) e intermediarios de políticas. El cambio y aprendizaje de políticas ocurre cuando existe cierto nivel de conflicto entre coaliciones. Realizamos una revisión de literatura, incluyendo historia de la Ley y notas en los medios de comunicación. Resultados: Identificamos dos coaliciones. La primera es pro-libertad individual y pretende resolver el problema con educación y promoción de la salud. La segunda es pro-determinantes sociales y define el problema como estructural. La primera coalición lanzó el programa “Elige Vivir Sano” en 2011 cuando estaban en el poder ejecutivo. Luego de las críticas de la oposición y la participación de intermediarios de políticas, el Programa se institucionalizó con una visión intersectorial. La falta de financiamiento permanente afecta la continuidad de la política, especialmente luego de un cambio en la coalición gobernante. Conclusiones: La Ley 20.670 se enmarca dentro de la ACF. Sin embargo, el aprendizaje de políticas se ralentizó porque el problema involucra aspectos sociales, conflicto entre creencias profundas de ambas coaliciones y falta de financiamiento permanente, afectando la continuidad de la política.

ABSTRACT Dogs are considered to be the main domestic reservoir associated with the transmission of Leishmania (L.) infantum chagasi to humans in endemic areas of visceral leishmaniasis in America. However, little is known about the role of canines as a source of infection in endemic areas of nonulcerated cutaneous leishmaniasis (NUCL). Therefore, the objective of the present study was to investigate the role of dogs as a possible reservoir of the parasite in Southern Honduras. Dogs (n = 107) living with individuals affected by NUCL were clinically examined and biological material was collected for parasitological and immunological diagnosis. Most animals showed a healthy appearance and a few presented slight weight loss (64%), alopecia (7%), onychogryphosis (5%) and skin lesions (1%). The overall seroprevalence of Leishmania infection based on the DDP ® quick test and/or in-house ELISA serological test was 41%. The presence of the parasite’s DNA was confirmed in 94% of the dogs; however, the average parasite load in the buffy coat was low at 6.09 parasites/µL, ranging between 0.221 and 50.2. The skin of seropositive dogs examined by histopathology using paraffin sections stained by hematoxylin and immunohistochemistry did not show cutaneous lesions or parasite amastigotes. Based on the absence of parasites in the skin and the low parasite load detected in the buffy coat, it seems that the dog does not represent a good source of infection for the vector in the endemic area of NUCL transmission in Southern Honduras. Other domestic and/or wild animals should be investigated.

ABSTRACT: Hypotrichosis congenita is a significant disease in Hereford cattle in Uruguay and has been reported worldwide. However, the causal mutation KRT71 has only been recently identified. This communication describes the clinical, histopathological, trichographic, and genetic findings of KRT71-hypotrichosis congenita observed in Hereford calves from two commercial farms. Five affected newborn calves, born in a herd of 15 purebred Polled HF cows, were examined in Farm 1, and one weaned calf in Farm 2. Skin biopsies for histopathology, hair samples for trichogram, and blood samples for genotyping were obtained from affected and control calves and the sire bull and mother cows. Affected animals exhibited a light brown coat with sparse, thin, curly or woolly haircoat. Hypotrichotic skin was dry, erythematous, and scaly. Trichogram analysis revealed thin, fragmented, curly hairs with irregular macro-melanosome groups. The main histopathological findings included marked follicular dysplasia with vacuolation, abnormally large trichohyaline granules in Huxley’s layer, and multiple melanin aggregates in hair fragments, matrix cells, and dysplastic follicles. There were no histological lesions of dermatitis. DNA analysis confirmed that hypotrichotic calves were homozygous for the KRT71 mutation, while one control calf, the bull, and cows in Farm 2 were heterozygous carriers. In conclusion, hypotrichosis congenita in Hereford cattle due to the KRT71 mutation is a color dilution follicular dysplasia.

RESUMO: A hipotricose congênita é uma doença significativa em bovinos Hereford no Uruguai e tem sido relatada em todo o mundo. No entanto, a mutação causal KRT71 foi identificada apenas recentemente. Esta comunicação descreve os achados clínicos, histopatológicos, tricográficos e genéticos da KRT71-hipotricose congênita observada em bezerros Hereford de duas fazendas comerciais diferentes. Cinco bezerros recém-nascidos afetados, nascidos em um rebanho de 15 vacas puras Polled HF, foram examinados na Fazenda 1, e um bezerro desmamado na Fazenda 2. Biópsias de pele para histopatologia, amostras de pelo para tricograma e amostras de sangue para genotipagem foram obtidas de bezerros afetados e controle, bem como do touro e das vacas. Animais afetados apresentaram uma pelagem marrom clara com pelos esparsos, finos, crespos ou lanosos. A pele hipotricótica era seca, eritematosa e escamosa. A análise do tricograma revelou pelos finos, fragmentados e crespos, com grupos irregulares de macro-melanossomas. Os principais achados histopatológicos incluíram displasia folicular acentuada com vacuolização e grânulos tricohialinos anormalmente grandes na camada de Huxley e múltiplos agregados de melanina em fragmentos de cabelo, células da matriz e folículos displásicos. Não foram observadas lesões histológicas de dermatite. A análise de DNA confirmou que os bezerros hipotricóticos eram homozigotos para a mutação KRT71, enquanto um bezerro controle, o touro e as vacas da Fazenda 2 eram portadores heterozigotos. Em conclusão, a hipotricose congênita em bovinos Hereford devido à mutação KRT71 é uma displasia folicular de diluição de cor.

Resumen La lesión de la mucosa asociada a cristales es un cuadro clínico importante en un subconjunto de pacientes urémicos a los que se les administran resinas de intercambio catiónico como el sulfonato de poliestireno sódico (Kayexalate) y sevelamer para el tratamiento de la hiperpotasemia y la hiperfosfatemia, respectivamente. La necrosis colónica en estos pacientes es rara, pero puede estar asociada a una lesión gastrointestinal mortal, con una tasa de mortalidad del 33%. Los secuestrantes de ácidos biliares son otro tipo de resina que teóricamente son biológicamente inertes. Se presentan dos casos de colitis asociada a cristales. El primer paciente tenía antecedentes de múltiples intervenciones quirúrgicas y patologías del tracto gastrointestinal, y estaba en manejo con colestiramina. Se realizó una sigmoidectomía en la que se encontraron varios focos de cristales. El segundo paciente tenía antecedente de enfermedad renal crónica que requirió el uso de Kayexalate y se presentó al servicio de urgencias con una hemorragia grave del tracto gastrointestinal inferior. Se realizó una colectomía parcial en la que se detectaron cambios morfológicos relacionados con el depósito de cristales. Las resinas pueden producir un amplio espectro de lesiones mortales de la mucosa, por lo que el diagnóstico precoz es fundamental para disminuir la mortalidad y mejorar el pronóstico. Sin embargo, es incierto si el consumo de colestiramina y Kayexalate, así como el depósito de sus cristales en el tracto gastrointestinal son el factor causal de la lesión de las mucosas. Por tanto, la presencia de resinas debería ayudar a establecer el diagnóstico correcto y el tratamiento médico oportuno para evitar resultados nocivos.

Abstract Crystal-associated mucosal injury is a crucial clinical picture in a subset of uremic patients who are given cation exchange resins such as sodium polystyrene sulfonate (Kayexalate) and sevelamer to treat hyperkalemia and hyperphosphatemia, respectively. Colonic necrosis in these patients is rare but may be associated with fatal gastrointestinal injury, with a mortality rate of 33%. Bile acid sequestrants are another type of resin that is theoretically biologically inert. Two cases of colitis associated with crystals are presented. The first patient had a history of multiple surgeries and pathologies of the gastrointestinal tract and was treated with cholestyramine. A sigmoidectomy was performed in which several crystal foci were found. The second patient had a history of chronic kidney disease requiring Kayexalate and attended the emergency department with severe lower GI bleeding. A partial colectomy was performed in which morphological changes related to the deposit of crystals were detected. Resins can cause a broad spectrum of malignant mucosal lesions, so early diagnosis is essential to reduce mortality and improve prognosis. However, it is uncertain whether the consumption of cholestyramine and kayexalate, as well as the deposition of their crystals in the GI tract, are the causative factor of mucosal damage. Therefore, resins should help establish the correct diagnosis and prompt medical treatment to avoid harmful results.

Abstract Background: Vulvar diseases are common in the general population and have a negative impact on the quality of life. Objectives: To describe our experience as dermatologists in the management of vulvar dermatosis consultations. Methods: A retrospective observational study was conducted with patients who attended monographic vulvar consultations over a 5-year period. Clinical information was obtained from the patient’s charts. Results: 148 women were studied. Their mean age was 43.24 years (standard deviation: 15.15 years), with ages ranging from 4 months to 80 years. 53.4% of patients took between 2 and 5 years to seek medical attention for the first time. The most frequent diagnosis was lichen sclerosus (41.9%), irritative eczema of the vulva (14.9%), and lichen simplex chronicus (10.1%). 83.8% reported anogenital itching, 66.2% pain, and 45.9% dyspareunia. The most frequently prescribed treatment was ultra-potent topical corticosteroids (clobetasol propionate; 41.2%). Patients with lichen sclerosus were significantly older than those who presented with any of the other diseases. No differences were found in terms of either the time of disease evolution or in symptom presentation. Study limitations: Retrospective study. Vulvar diseases with an infectious cause are usually managed in primary care, therefore, were not included. All patients were recruited from a single private hospital which limits the comparisons with the public health system. Conclusions: Vulvar diseases frequently occur and are associated with high morbidity. It is essential to promote the development of specific vulvar consultations in hospitals. Specialties such as dermatology, gynecology, urology, or physiotherapy must be part of these units.

RESUMEN La pandemia por el nuevo coronavirus denominado SARS-CoV-2 plantea retos sin precedentes en la atención de la salud. Entre ellos se cuenta el aumento en los casos de delirium. La enfermedad grave por SARS-CoV-2, COVID-19, tiene vulnerabilidades comunes con el delirium y produce alteraciones en órganos como el pulmón o el cerebro, entre otros, que tienen potencial para precipitar el trastorno mental; de hecho, este puede ser la primera manifestación de la infección, antes de la fiebre, el malestar general, la tos o las alteraciones respiratorias. Está ampliamente sustentado que el delirium incrementa la morbilidad y la mortalidad de quienes lo padecen durante una hospitalización, por lo que se debe buscar activamente para realizar las intervenciones pertinentes. Ante la ausencia de evidencia sobre el abordaje del delirium en el contexto de la COVID-19, se elaboró este consenso sobre tres aspectos fundamentales: diagnóstico, tratamiento no farmacológico y tratamiento farmacológico, en pacientes ingresados en el hospital general. El documento contiene recomendaciones sobre uso sistemático de herramientas diagnósticas, cuándo hospitalizar al paciente con delirium, la aplicación de acciones no farmacológicas dentro de las restricciones que impone la COVID-19 y la utilización de antipsicóticos teniendo en cuenta los efectos secundarios más relevantes y las interacciones farmacológicas.

ABSTRACT The pandemic caused by the new coronavirus named SARS-CoV-2 poses unprecedented challenges in the health care. Among them is the increase in cases of delirium. The severe SARS-CoV-2 disease, COVID-19, has common vulnerabilities with delirium and produces alterations in organs such as the lungs or the brain, among others, which have the potential to trigger the mental disorder. In fact, delirium may be the first manifestation of the infection, before fever, general malaise, cough or respiratory disturbances. It is widely supported that delirium increases the morbidity and mortality in those who suffer from it during hospitalization, so it should be actively sought to carry out the relevant interventions. In the absence of evidence on the approach to delirium in the context of COVID-19, this consensus was developed on three fundamental aspects: diagnosis, non-pharmacological treatment and pharmacological treatment, in patients admitted to the general hospital. The document contains recommendations on the systematic use of diagnostic tools, when to hospitalize the patient with delirium, the application of non-pharmacological actions within the restrictions imposed by COVID-19, and the use of antipsychotics, taking into account the most relevant side effects and pharmacological interactions.

Resumen Se llevó a cabo un estudio bianual en un área protegida del Sistema serrano de Ventania donde la estepa pampeana y las cabeceras de los arroyos mantienen las condiciones cercanas a las naturales. Se analizó la composición y la estructura del ensamble de Chironomidae (Insecta: Diptera) en dos arroyos prístinos y su relación con las variables fisicoquímicas. Se identificaron 15444 especímenes, correspondientes a 37 especies distribuidas en 4 subfamilias. El ensamble presentó una estructura más similar a las reportadas para los arroyos de la región Andina o extra Andina, que la de otras áreas de la región pampeana. Orthocladiinae presentó la mayor riqueza taxonómica y densidad, mientras que Podonominae las menores. Chironominae estuvo mejor representada aguas abajo, presentando géneros con distribución amplia. De los 5 géneros de Podonominae reportados en la región Andina-Patagónica, 3 de ellos (Podonomus Philippi, ParochlusEnderlein y Podonomopsis Brundin) fueron colectados. La presencia de Podonomus y Podonomopsis representa el registro de menor altitud para ambos géneros. Las variables fisicoquímicas difirieron entre las estaciones, y la conductividad fue la única que mostró un gradiente altitudinal. Las especies que prevalecieron en los sitios pedemontanos, correlacionaron positivamente con la conductividad. Con pocas excepciones, las especies recolectadas se registraron en otoño y primavera. En el arroyo Toro, la densidad fue significativamente mayor en la primavera del segundo año. Nuestro estudio aporta información de base sobre la ecología y la sistemática de un grupo de insectos ampliamente utilizado en estudios de biomonitoreo de ambientes acuáticos, lo cual resulta muy importante para respaldar la importancia de preservar esta área.

Abstract A two-year study was conducted in a conservation area of the Ventania hill system where the Pampean grassy steppes and their headwater springs maintain conditions close to natural ones. The composition and the structure of Chironomidae (Insecta: Diptera) along two short hill pristine streams and their relationship with the physicochemical variables were analyzed. A total of 15444 individuals belonging to 37 species of four subfamilies were identified. An assemblage structure more similar to those described for Andean or Argentine extra-Andean hill streams than to those of the surrounding Pampas was observed. Orthocladiinae showed the highest and Podonominae the lowest taxonomic richness and density. Chironominae was best represented downstream by genera with wide distribution. From the five Podonominae genera reported in the Andean-Patagonic region, three of them (Podonomus Philippi, Parochlus Enderlein and PodonomopsisBrundin) were collected. The presence of Podonomus and Podonomopsis represent the reports at lower altitudes for both genera. The physicochemical variables differed between seasons, and only water conductivity showed an altitudinal gradient. Those species prevailing in piedmont sites correlated positively with conductivity. With few exceptions, the species collected were recorded in both seasons. In Toro stream, density was significantly highest in Spring of the second year. This study provides the ecological and systematic baseline knowledge of an insect group widely used in biomonitoring of aquatic environments, to provide biological information that supports the importance of preserving this area.

Resumo Objetivo Estimar a prevalência de níveis inadequados de vitamina D e seus fatores associados para mulheres em idade fértil no Brasil. Métodos Uma revisão sistemática foi realizada (última atualização em maio de 2020). As meta-análises foram realizadas usando o inverso da variância para o modelo fixo com cálculo de proporção sumarizada por transformação arco-seno duplo de Freeman-Tukey. A qualidade metodológica e de reporte foi avaliada usando a ferramenta do Joanna Briggs Institute para estudos de prevalência. Resultados Nossa revisão identificou 31 estudos, compreendendo 4.006 participantes. Todos os estudos apresentaram pelo menos uma limitação, principalmente devido ao uso de amostra de conveniência e tamanho amostral pequeno. As prevalências gerais de deficiência, insuficiência e deficiência de vitamina D foram 35% (intervalo de confiança, IC 95%: 34-37%), 42% (IC 95%: 41-44%) e 72% (IC 95%: 71-74%), respectivamente. Conclusão Embora a magnitude da prevalência de níveis inadequados de vitamina D seja incerta, a evidência sugere que presença de deficiência ou insuficiência de vitamina D em mulheres em idade reprodutiva pode causar problemas moderados a graves.

Abstract Objective To estimate the prevalence of inadequate vitamin D level and its associated factors for women of childbearing age in Brazil. Methods A systematic reviewwas conducted (last updatedMay 2020).Meta-analyses were performed using the inverse-variance for fixed models with summary proportion calculation by Freeman-Tukey double arcsine. Reporting and methodological quality were assessed using the Joanna Briggs Institute tool for prevalence studies. Results Our review identified 31 studies, comprising 4,006 participants. All the studies had at least one weakness, mainly due to the use of convenience sampling and small sample size. The overall prevalence of vitamin D deficiency, insufficiency, and both deficiency and insufficiency were 35% (confidence interval, 95%CI: 34-37%), 42% (95%CI: 41-44%), and 72% (95%CI: 71-74%), respectively. Conclusion Although the magnitude of the prevalence of inadequate levels of vitamin D is uncertain, the evidence suggests that presence of vitamin D deficiency or insufficiency in women of reproductive age can cause moderate to severe problems.
