Infarto pulmonar: signos que no debemos dejar pasar en TC de tórax sin contraste / Pulmonary infarction: the signs that we must not miss in chest CT without contrast

Resumen El infarto pulmonar (IP) resulta de la oclusión de las arterias pulmonares distales que generan isquemia, hemorragia y finalmente necrosis del parénquima pulmonar, siendo la causa más frecuente la embolia pulmonar (EP). El diagnóstico oportuno de IP permite el inicio precoz del tratamiento y el respectivo manejo de sostén, disminuyendo así la morbimortalidad asociada. El objetivo de esta revisión es remarcar la importancia de identificar aquellos signos, que en la tomografía computada (TC) sin contraste son altamente sensibles y específicos para el diagnóstico de IP. La TC de alta resolución constituye el método que más información aporta, pudiendo observar signos clásicos de IP como la opacidad en forma de cuña, opacidad con radiolucencia central y el signo del vaso nutricio; así como signos con alto valor predictivo negativo para IP, como la opacidad consolidativa con broncograma aéreo, sugestivo de otras patologías, ya sean infecciosas o tumorales.

Abstract Pulmonary infarction (PI) results from occlusion of the distal pulmonary arteries leading to ischemia, hemorrhage, and necrosis of the pulmonary parenchyma. The most common cause of pulmonary infarction is pulmonary embolism (PE). Early diagnosis of PI allows early initiation of treatment and supportive care, thus reducing the associated morbidity and mortality. This review aims to highlight the importance of identifying signs that are highly sensitive and specific for the diagnosis of PE even without IV contrast. High-resolution computed tomography (CT) is the method that provides the most information, as it observes classic signs of PI such as wedge-shaped opacity, central lucencies in peripheral consolidation, and the feeding vessel sign, as well as signs with high negative predictive value such as consolidating opacity with air bronchogram that are suggestive of other pathologies, whether infectious or tumoural.

Anatomia de A a Z - Desvendando a terminologia anatômica nas redes sociais: Relato de experiência / Anatomy from A to Z - Unraveling anatomical terminology on social networks: An experience report

Os termos médicos utilizados na morfologia eram provenientes de um nome próprio, com o intuito de homenagear os que descobriram ou apresentaram a estrutura anatômica, conhecidos como epônimos. Buscando unificar a linguagem anatômica e facilitar o processo de ensino, em 1989 foi criado o Comitê Federativo Internacional de Terminologia Anatômica (FICAT), cujo propósito era revisar os epônimos e atualizar a terminologia anatômica. Com o objetivo de apresentar os fundamentos e conhecimentos sobre a origem das terminologias anatômicas nas mídias sociais, a Liga Acadêmica de Anatomia da Universidade Federal de Alfenas (LAANAT/UNIFAL-MG), por meio do projeto de extensão "Anatomia de A a Z", divulgou conhecimentos científicos acerca da etimologia anatômica. Foram feitas postagens semanais no Instagram e no Facebook, a partir de publicações elaboradas pelos ligantes, supervisionadas pelos professores coordenadores e desenvolvidas no aplicativo Canva. Cada postagem seguiu sequen-cialmente as letras do alfabeto (de A a Z) e eram compostas da etimologia de duas estruturas anatômicas. Frente a uma análise de dados, observamos que em 23 publicações, alcançamos 712 curtidas, 194 compartilhamentos, 44 publicações salvas, 4739 contas alcançadas e 6608 impressões. A LAANAT promoveu, de forma clara e objetiva, a divulgação de conhecimentos das terminologias anatômicas ao público geral (AU).

The medical terms used in morphology were derived from proper nouns to honor those who discovered or presented the anatomical structure, known as eponyms. In 1989, anatomists founded the Federative International Program on Anatomical Terminologies (FICAT) to unify anatomical language and facilitate the teaching process by reviewing eponyms and updating nomenclature. Intending to present the fundamentals and knowledge about the origin of anatomical terminologies on social media, the Academic League of Anatomy at the Federal University of Alfenas (LAANAT/UNIFAL-MG), through the extension project "Anatomy from A to Z" disseminated scientific knowledge about anatomical etymology. Weekly posts were made on Instagram and Facebook, based on publications elaborated by the League members, supervised by the professors, and developed on the Canva application. Each post sequentially followed the letters of the alphabet (from A to Z) and consisted of the etymology of two anatomical structures. In analyzing the data, we observed that in 23 publications, we achieved 712 likes, 194 shares, 44 saved posts, 4739 reached accounts, and 6608 prints. LAANAT promoted, clearly and objectively, the dissemination of knowledge of anatomical terminologies to the general public

Molecular detection of SARS-CoV-2 in Argentina: Evaluation of alternative diagnostic tools for the decentralization of the diagnosis

Abstract The rocketing number of COVID-19 cases highlighted the critical role that diagnostic tests play in medical and public health decision-making to contain and mitigate the SARS-CoV-2 pandemic. This study reports the evaluation and implementation of different tests for the molecular detection of SARS-CoV-2 in the central region of Argentina. We evaluated 3 real time RT-PCR kits (GeneFinder COVID-19 Plus RealAmp Kit, DisCoVery SARS-CoV-2 RT-PCR Detection Kit and WGene SARS-CoV-2 RT Detection), 2 nucleic acid extraction methods [MagaBio plus Virus DNA/RNA Purification Kit II (BioFlux), 35-min vs. 9-min, a pre-analytical reagent (FlashPrep®) and 2 isothermal amplification tests (Neokit Plus and ELA CHEMSTRIP®). The order according to the best performance of the 3 real-time RT-PCR kits evaluated was: DisCoVery > GeneFinderTM> WGene. The 2 RNA extraction methods showed similar good results: MagaBio plus Virus RNA Purification Kit II (BioFlux) 9-min was selected due to its faster performance. FlashPrep® reagent showed excellent results to perform direct RNA detection. Isothermal amplification assays showed acceptable sensitivity and specificity values (>80%), except in samples with Ct> 30. Our data show optimal real time RT-PCR kits and alternative molecular methods for SARS-CoV-2 diagnostic. These alternative assays proved to be aceptable.

Alimentação fora do lar: análise do ambiente alimentar de shopping centers de Campo Grande, Mato Grosso do Sul, Brasil / Eating away from home: analysis of the food environment of shopping malls in Campo Grande, Mato Grosso do Sul, Brazil / Alimentación fuera del hogar: análisis del entorno alimentario de los centros comerciales de Campo Grande, Mato Grosso do Sul, Brasil

Objetivo: Caracterizar o ambiente alimentar dos shopping centersde Campo Grande/MS, tendo em vista, a relevância de analisar os produtos que estão disponíveis a este público bem como sua qualidade nutricional. Método: Foram avaliados 124 Unidades de Produção de Refeições (UPR) nos shopping centers, por observação direta do cardápio, bufê ou fachada. Para coleta de dados foi utilizado o instrumento NutritionEnvironmentMeasuresSurveyRestaurants (NEMS-R). As variáveis coletadas a partir do referido instrumento foram tipos de unidades, sistema de gestão, serviços de mesa, tipos de alimentos e bebidas disponíveis, facilitadores e barreiras ao consumo de alimentos saudáveis. Resultados: Foram encontrados 29,0% de restaurantes àla carte; 8,1% de restaurantes tipo autosserviço; 36,3% de lanchonetes e 26,6% dos demais (bares, sorveterias, carrinhos/quiosques). Em relação aos tipos de gestão 77,4% são franquias. Entre os alimentos mais comercializados destaca-se as bebidas açucaradas, acessível em 79,8% das unidades e doces/sobremesas em 50,0%. Grande parte das unidades avaliadas não apresenta facilitadores para a alimentação saudável, sendo que mais de 90,0% das unidades não ofereceram opções de porções reduzidas, trocas saudáveis e opções saudáveis para crianças. A maior barreira encontrada foi a oferta de porções maiores por um pequeno acréscimo de preço (63,7%). Conclusão: O ambiente alimentar encontrado pode dificultar o acesso aos alimentos saudáveis. Assim, sugere-se que políticas públicas de segurança alimentar e nutricional, sejam implementadas, de forma a promover o maior acesso aos alimentos saudáveis que contribuem para a melhoria da qualidade de vida da população.

Objective: To characterize the food environment of shopping centers in Campo Grande/MS, in view the relevance of analyzing the products that are available to this public as well as their nutritional quality. Method: A total of 124 restaurants were evaluated in the shopping malls, by direct observation of the menu, buffet orfacade. For date collection was used the instrument Nutrition Environment Measures Survey Restaurants (NEMS-R). The variables collected were types of units, management system, table services, types of food and drinks available, facilitators and barriers to healthy food consumption. Results: 29.0% of the evaluated restaurants were à la carte; 8.1% self- service; 36.3% snack bars and 26.6% were bars, ice cream parlors or stands/kiosks. Regarding the types of management, 77.4% were franchises. Among the most commercialized foods, sugary drinks stand out, accessible in 79.8% of the units and sweets / desserts in 50.0%. Most of the units evaluated do not have facilitators for healthy eating, and more than 90.0% of the units did not offer reduced portion options, healthy exchanges and healthy options for children.

Impact of Alcohol Consumption on Quality of Life, Depressive Mood and Metabolic Syndrome in Obstructive Lung Disease Patients: Analysis of Data from Korean National Health and Nutrition Examination Survey from 2014 and 2016 / 결핵및호흡기질환

Background@#The objective of this study was to investigate whether alcohol consumption might affect the quality of life (QOL), depressive mood, and metabolic syndrome in patients with obstructive lung disease (OLD). @*Methods@#Data were obtained from the Korean National Health and Nutrition Examination Survey from 2014 and 2016. OLD was defined as spirometry of forced expiratory volume in 1 second/forced vital capacity <0.7 in those aged more than 40 years. QOL was evaluated using the European Quality of Life Questionnaire-5D (EQ-5D) index. Patient Health Questionnaire-9 (PHQ-9) was used to assess the severity of depressive mood. Alcohol consumption was based on a history of alcohol ingestion during the previous month. @*Results@#A total of 984 participants with OLD (695 males, 289 females, age 65.8±9.7 years) were enrolled. The EQ-5D index was significantly higher in alcohol drinkers (n=525) than in non-alcohol drinkers (n=459) (0.94±0.11 vs. 0.91±0.13, p=0.002). PHQ- 9 scores were considerably lower in alcohol drinkers than in non-alcohol drinkers (2.15±3.57 vs. 2.78±4.13, p=0.013). However, multiple logistic regression analysis showed that alcohol consumption was not associated with EQ-5D index or PHQ-9 score. Body mass index ≥25 kg/m2, triglyceride ≥150 mg/dL, high-density lipoprotein <40 mg/dL in men and <50 mg/dL in women, and blood pressure ≥130/85 mm Hg were significantly more common in alcohol drinkers than in non-alcohol drinkers (all p<0.05). @*Conclusion@#Alcohol consumption did not change the QOL or depressive mood of OLD patients. However, metabolic syndrome-related factors were more common in alcohol drinkers than in non-alcohol drinkers.

Inhibitory Effect of Cinobufotalin on Macrophage Inflammatory Factor Storm and Its Mechanism / 中国实验血液学杂志

OBJECTIVE@#To investigate the inflammatory effects of Cinobufotalin on monocytes in resting state and macrophages in activated state and its molecular mechanism.@*METHODS@#THP-1 cells were stimulated with Phorbol 12-myristate 13-acetate to induce differentiation into macrophages. Lipopolysaccharides was added to activate macrophages in order to establish macrophage activation model. Cinobufotalin was added to the inflammatory cell model for 24 h as a treatment. CCK-8 was used to detect cell proliferation, Annexin V /PI double staining flow cytometry was used to detect cell apoptosis, flow cytometry was used to detect macrophage activation, and cytometric bead array was used to detect cytokines. Transcriptome sequencing was used to explore the gene expression profile regulated by Cinobufotalin. Changes in the significantly regulated molecules were verified by real-time quantitative polymerase chain reaction and Western blot.@*RESULTS@#1∶25 concentration of Cinobufotalin significantly inhibited the proliferation of resting monocytes(P<0.01), and induced apoptosis(P<0.01), especially the activated macrophages(P<0.001, P<0.001). Cinobufotalin significantly inhibited the activation of macrophages, and significantly down-regulated the inflammatory cytokines(IL-6, TNF-α, IL-1β, IL-8) released by activated macrophages(P＜0.001). Its mechanism was achieved by inhibiting TLR4/MYD88/P-IκBa signaling pathway.@*CONCLUSION@#Cinobufotalin can inhibit the inflammatory factors produced by the over-activation of macrophages through TLR4/MYD88/P-IκBa pathway, which is expected to be applied to the treatment and research of diseases related to the over-release of inflammatory factors.

Punicalagin inhibits hepatic lipid deposition in obese mice via AMPK/ACC pathway / 中国中药杂志

Hepatic lipid deposition is one of the basic manifestations of obesity, and nowadays pharmacological treatment is the most important tool. Punicalagin(PU), a polyphenol derived from pomegranate peel, is a potential anti-obesity substance. In this study, 60 C57BL/6J mice were randomly divided into a normal group and a model group. After establishing a model of simple obesity with a high-fat diet for 12 weeks, the successfully established rat models of obesity were then regrouped into a model group, an orlistat group, a PU low-dose group, a PU medium-dose group, and a PU high-dose group. The normal group was kept on routine diet and other groups continued to feed the high-fat diet. The body weight and food intake were measured and recorded weekly. After 8 weeks, the levels of the four lipids in the serum of each group of mice were determined by an automatic biochemical instrument. Oral glucose tole-rance and intraperitoneal insulin sensitivity were tested. Hemoxylin-eosin(HE) staining was applied to observe the hepatic and adipose tissues. The mRNA expression levels of peroxisome proliferators-activated receptor γ(PPARγ) and C/EBPα were determined by real-time quantitative polymerase chain reaction(Q-PCR), and the mRNA and protein expression levels of adenosine 5'-monophosphate-activated protein kinase(AMPK), anterior cingulate cortex(ACC), and carnitine palmitoyltransferase 1A(CPT1A) were determined by Western blot. Finally, the body mass, Lee's index, serum total glyceride(TG), serum total cholesterol(TC), and low-density lipoprotein cholesterol(LDL-C) levels were significantly higher and high-density lipoprotein cholesterol(HDL-C) levels were significantly lower in the model group as compared with the normal group. The fat deposition in the liver was significantly increased. The mRNA expression levels of hepatic PPARγ and C/EBPα and the protein expression level of ACC were increased, while the mRNA and protein expression levels of CPT-1α(CPT1A) and AMPK were decreased. After PU treatment, the above indexes of obese mice were reversed. In conclusion, PU can decrease the body weight of obese mice and control their food intake. It also plays a role in the regulation of lipid metabolism and glycometabolism metabolism, which can significantly improve hepatic fat deposition. Mechanistically, PU may regulate liver lipid deposition in obese mice by down-regulating lipid synthesis and up-regulating lipolysis through activation of the AMPK/ACC pathway.

Effect of acupuncture combined with infantile tuina on intestinal flora in children with tic disorders / 中国针灸

OBJECTIVE@#To observe the effect of acupuncture combined with infantile tuina on intestinal flora and its efficacy in children with tic disorders (TD), and to explore its mechanism.@*METHODS@#A total of 15 children with TD were recruited as an observation group and 10 healthy children as a healthy control group. Regulating spleen and stomach acupuncture combined with infantile tuina were received in the observation group. First, acupuncture was applied to Zhongwan (CV 12), Tianshu (ST 25), Guanyuan (CV 4), Hegu (LI 4), Zusanli (ST 36), etc., and then abdominal massage and other tuina techniques were applied, once a day, 6 times a week, 2 weeks as a course of treatment, a total of 2 courses of treatment were required. No intervention was given in the healthy control group. In the observation group, Yale global tic severity scale (YGTSS) score and TCM syndrome score were compared before treatment and after 1 and 2 courses of treatment. 16S rRNA sequencing technology was used to detect the intestinal flora in the healthy control group and before and after treatment in the observation group.@*RESULTS@#After 1 and 2 courses of treatment, the scores of YGTSS and TCM syndrome in the observation group were lower than those before treatment (P<0.01, P<0.05). Compared with the healthy control group, the number of operational taxonomic units (OTU) and indexes of Chao1, Sobs, Ace and Shannon were decreased in the observation group before treatment (P<0.05, P<0.01). Compared with before treatment, the number of OTU and indexes of Chao1, Sobs, Ace and Shannon were increased in the observation group after treatment (P<0.01, P<0.05). Compared with the healthy control group, the relative abundance of Firmicutes in the observation group before treatment was decreased (P<0.001), while the relative abundance of Bacteroidetes, Bacteroides and Erysipelatoclostridium was increased (P<0.001, P<0.05). Compared with before treatment, the relative abundance of Bacteroidetes in the observation group was decreased (P<0.001) after treatment, while the relative abundance of Actinobacteria, Bifidobacterium and Atopobium was increased (P<0.05, P<0.01).@*CONCLUSION@#Acupuncture combined with infantile tuina based on the principle of regulating spleen and stomach could effectively improve TD symptoms in children, which may be related to regulating the diversity of intestinal flora, increasing beneficial bacteria, maintaining intestinal microecological balance, and playing a role in improving neurological disorders.

Outcomes following anastomotic leak from rectal resections, including bowel function and quality of life

Purpose@#Anastomotic leak (AL) is an uncommon but potentially devastating complication after rectal resection. We aim to provide an updated assessment of bowel function and quality of life after AL, as well as associated short- and long-term outcomes. @*Methods@#A retrospective audit of all rectal resections performed at a colorectal unit and associated private hospitals over the past 10 years was performed. Relevant demographic, operative, and histopathological data were collected. A prospective survey was performed regarding patients’ quality of life and fecal continence. These patients were matched with nonAL patients who completed the same survey. @*Results@#One hundred patients (out of 1,394 resections) were included. AL was contained in 66.0%, not contained in 10.0%, and only anastomotic stricture in 24.0%. Management was antibiotics only in 39.0%, percutaneous drainage in 9.0%, operative abdominal drainage in 19.0%, transrectal drainage in 6.0%, combination of percutaneous drainage and transrectal drainage in 2.0%, and combination abdominal/transrectal drainage in 1.0%. The 1-year stoma rate was 15.0%. Overall, mean Fecal Incontinence Severity Instrument scores were higher for AL patients than their matched counterparts (8.06±10.5 vs. 2.92±4.92, P=0.002). Patients with an AL had a mean EuroQol visual analogue scale (EQ-VAS) of 76.23±19.85; this was lower than the matched mean EQ-VAS for non-AL patients of 81.64±18.07, although not statistically significant (P=0.180). @*Conclusion@#The majority of AL patients in this study were managed with antibiotics only. AL was associated with higher fecal incontinence scores in the long-term; however, this did not equate to lower quality of life scores.

The role of volume and intensity on the association between physical activity and mental health among adolescents: a cross-sectional study / O papel do volume e da intensidade na associação entre atividade física e saúde mental em adolescentes: um estudo transversal

Abstract Objective: To analyze the association between volume and intensity of physical activity and mental health among adolescents. Methods: Cross-sectional study with 604 Brazilian adolescents. Data were assessed using a self-report questionnaire. The outcomes were suicidal ideation, suspicion of common mental disorders, and negative self-perception of mental health. The independent variables were leisure physical activity at low and moderate-to-vigorous intensities. Volume was analyzed in two ways: any volume (presence vs absence), and volume classified according to amount in minutes of weekly physical activity: inactive (0), low active (1-419), and high active (≥420). Poisson regression was performed to estimate prevalence ratios. Results: Any volume of moderate-to-vigorous physical activity was significantly associated with a lower prevalence ratio of all outcomes (PR 0.67 to 0.77). Compared to inactive adolescents, those who were classified as low active for moderate-to-vigorous intensity, presented a lower likelihood of having suicidal ideation, suspicion of common mental disorders, and negative self-perception of mental health (PR 0.70 to 0.76). Furthermore, high active adolescents in moderate-to-vigorous physical activity presented lower suicidal ideation and negative self-perception of mental health (PR 0.62 and 0.57). Conclusions: The promotion of moderate-to-vigorous intensity physical activity at any volume can benefit the mental health of adolescents, however, no association was evidenced for low intensity physical activity.

Resumo Objetivo: Analisar a associação entre o volume e intensidade da atividade física e a saúde mental de adolescentes. Métodos: Estudo transversal que envolveu 604 adolescentes brasileiros. Os dados foram coletados por meio de um questionário autorrelatado. Os desfechos foram ideação suicida, suspeita de transtornos mentais comuns e autopercepção negativa de saúde mental. A variável independente foi a atividade física em tempo livre nas intensidades leve e moderada a vigorosa. O volume foi analisado de duas formas: qualquer volume (presença vs. ausência); e de acordo com a quantidade de atividade física semanal em minutos — inativos (0), pouco ativos (1-419) e altamente ativos (≥420). A regressão de Poisson foi realizada para estimar as razões de prevalência (RP). Resultados: Qualquer volume de atividade física de intensidade moderada a vigorosa foi significativamente associado à menor razão de prevalência de todos os desfechos (RP 0,67 a 0,77). Comparados aos adolescentes inativos, aqueles que foram classificados como pouco ativos na intensidade moderada a vigorosa apresentaram menor probabilidade de ter ideação suicida, suspeita de transtornos mentais comuns e autopercepção negativa de saúde mental (RP 0,70 a 0,76). Da mesma forma, adolescentes altamente ativos na intensidade moderada a vigorosa apresentaram menor ideação suicida e autopercepção negativa de saúde mental (RP 0,62 e 0,57). Conclusões: A promoção de atividade física moderada a vigorosa em qualquer volume pode beneficiar a saúde mental de adolescentes, no entanto nenhuma associação foi evidenciada para a atividade física na intensidade leve.

Intestinal microbiome characterization of adult Brazilian men with psoriasis compared to omnivore and vegetarian controls

Abstract Background Psoriasis is a chronic inflammatory disease associated with systemic inflammation and comorbidities. Changes in the composition of the intestinal microbiome are involved in the pathogenesis of inflammatory diseases and metabolic syndrome. Characterizing the intestinal microbiome of patients with psoriasis may be relevant for the understanding of its clinical course and comorbidity prevention. Objective To characterize the intestinal microbiome of men with psoriasis compared to omnivore and vegetarian controls (without psoriasis). Method Cross-sectional study of 42 adult males: 21 omnivores with psoriasis; and controls: 14 omnivores and 7 vegetarian individuals. The characterization of the intestinal microbiome was performed by metagenomic analysis. Serum levels of lipopolysaccharide-binding protein (LPB) and C-reactive protein (CRP) were evaluated. Results The groups differed from each other regarding nutritional aspects and microbiome; individuals with psoriasis had a higher consumption of protein and lower consumption of fibers. Levels of LPB, CRP, and the Firmicutes/Bacteroidetes ratio were higher in the group with psoriasis than in the vegetarian group (p < 0.05). The genera Prevotella, Mogibacterium, Dorea, Bifidobacterium and Coprococcus, differed in the group with psoriasis compared to vegetarians; the genera Mogibacterium, Collinsella and Desulfovibrio differed from omnivores. A microbiome pattern linked to psoriasis (plsPSO) was identified, which was associated with higher LPB levels (rho = 0.39; p = 0.02), and lower dietary fiber intake (rho = −0.71; p < 0.01). Study limitations Only adult men were evaluated. Conclusion A difference was identified in the intestinal microbiome of adult men with psoriasis when compared to healthy omnivores and vegetarian controls. The identified microbiome pattern was correlated with dietary fiber intake and serum levels of LPB.

Protective Effects of Fuziline on Dobutamine-Induced Heart Damage in Mice

ABSTRACT Introduction: Fuziline is one of the many antioxidants currently being tested to treat cardiac damage. In our study, histopathological and biochemical effects of fuziline were investigated in mice with dobutamine-induced heart damage in vitro. Methods: Thirty-two adult male BALB/c mice, average weight of 18-20 g, were randomly divided into four groups - Group 1 (sham, n=8), Group 2 (control, dobutamine, n=8), Group 3 (treatment 1, dobutamine + fuziline, n=8), and Group 4 (treatment 2, fuziline, n=8). Biochemical parameters and total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI) values were measured. Interleukin 1 beta (IL-1β), NLR family, pyrin domain containing protein 3 (NLRP3), 8-hydroxy-deoxyguanosine (8-OHDG), gasdermin D (GSDMD), and galectin 3 (GAL-3) levels were analyzed by enzyme-linked immunosorbent assay method, and histopathological examination of heart tissues was performed. Results: When dobutamine + fuziline and fuziline groups were compared, troponin-I (P<0.05), NLRP3 (P<0.001), GSDMD (P<0.001), 8-OHDG (P<0.001), IL-1β (P<0.001), and GAL-3 (P<0.05) were found to be statistically significant. TOS level was the highest in the dobutamine group (P<0.001) and TAS level was the highest in the fuziline group (P<0.001). OSI level was statistically significant between the groups (P<0.001). In histopathological examination, focal necrosis areas were smaller in the dobutamine + fuziline group than in the dobutamine group, and cardiac myocytes were better preserved. Conclusion: Fuziline markedly reduced cardiac damage and pyroptosis in mice with dobutamine-induced heart damage by lowering the levels of GSDMD, 8-OHDG, IL-1β, and GAL-3. It also prevented necrosis of cardiac myocytes in histopathological evaluation.

Detección clonal de cepas parentales de streptococcus agalactiae Lehmann y Neumann por amplificación aleatoria de ADN polimórfico / Clonal detection of streptococcus agalactiae Lehmann and Neumann parental strains by random amplification of polymorphic DNA

RESUMEN Streptococcus agalactiae (SGB) produce infecciones invasivas en neonatos siendo la transmisión materna la más frecuente. Estudios epidemiológicos utilizan técnicas moleculares que evalúan la diversidad genética, entre ellas la de amplificación aleatoria de ADN polimórfico (RAPD) que resulta ser accesible, sensible y utiliza cebadores arbitrarios para amplificar segmentos polimórficos de ADN mediante PCR. El objetivo fue determinar la relación clonal entre aislamientos de SGB recuperados de madres y sus respectivos recién nacidos. Se estudiaron por RAPD cuatro parejas de aislamientos de SGB obtenidos de hisopados vagino-rectales de madres y de hemocultivos de sus neonatos. Se utilizaron los cebadores OPS11, OPB17 y OPB18 para seleccionar uno con capacidad de discriminar entre cepas no relacionadas genéticamente. Se utilizó la fórmula de Hunter-Gaston que establece el índice de discriminación (D), cuando D>0,90 se considera que los aislamientos pertenecen a clones diferentes. Los perfiles de amplificación para los ocho aislamientos, empleando independientemente cada cebador, permitieron calcular un D=1 para OPS11, y D=0,84 para OPB17 y OPB18. Por lo tanto, OPS11 fue seleccionado para el estudio de la relación clonal de los aislamientos, encontrándose perfiles de amplificación similares por RAPD para cada par de cepas madre-recién nacido. Se observaron diferentes perfiles de amplificación entre los pares de cepas madre-recién nacido, lo que revela la discriminación entre cepas no relacionadas, resultados confirmados por electroforesis en campo pulsante (PFGE). Estos resultados indican transmisión vertical para cada caso estudiado y robustez del cebador OPS11. Se encontraron condiciones apropiadas del ensayo de RAPD, lo que es útil para estudios epidemiológicos.

ABSTRACT Streptococcus agalactiae (GBS) causes invasive infections in newborns, being the most frequent the maternal transmission. Epidemiological studies use molecular techniques that assess genetic diversity, including random amplification of polymorphic DNA (RAPD) that is found to be accessible, sensitive and uses arbitrary primers to amplify polymorphic segments of DNA by PCR. The objective was to determine the clonal relationship between GBS strains recovered from mothers and their respective newborns. Four pairs of GBS isolates obtained from vaginal-rectal swabs of mothers and blood cultures of their newborns were studied with RAPD. Primers OPS11, OPB17 and OPB18 were used to select one with the ability to discriminate between non-genetically related strains. The Hunter-Gaston formula that establishes the discrimination index (D) was used; when D>0.90, it is considered that the isolates belong to different clones. The amplification profiles for the eight isolates, using each primer independently, allowed to calculate a D=1 for OPS11, and D=0.84 for OPB17 and OPB18. Therefore, OPS11 was selected for the study of the clonal relationship of the isolates, and similar amplification profiles were found by RAPD for each mother-newborn pair of GBS isolates. Different amplification profiles were observed between pairs of mother-newborn strains, which reveals the discrimination between unrelated strains, confirmed by pulsating field electrophoresis (PFGE). These results indicated vertical transmission for each studied case and robustness of the OPS11 primer. Appropriate conditions of the RAPD trial were found, which is useful for epidemiological studies.

Escrofuloderma en paciente pediátrico / Scrofuloderma in a pediatric patient

La tuberculosis (TB) cutánea es una forma rara de tuberculosis extrapulmonar y puede tener diversas manifestaciones clínicas. La afectación cutánea puede producirse como resultado de inoculación exógena, diseminación contigua desde un foco de infección, o mediante la propagación hematógena desde un foco distante 1. Las formas multibacilares de localización cutánea siguen siendo, con mucho, las más comunes en los niños 2. La tuberculosis cutánea representa sólo el 1-2% de las formas extrapulmonares de TB. Se clasifica en varias variantes, y la escrofulodermia es una forma de tuberculosis endógena. Afecta a personas de todas las edades, sin embargo, los niños, los adolescentes y los ancianos se ven muy afectados, debido a la incapacidad inmunológica para contener la infección por micobacterias. La escrofulodermia puede presentarse de forma aislada o coexistir con formas pulmonares y diseminadas de TB. Se presenta como nódulos eritematosos que se fistulizan y descargan material caseoso y purulento 3. Los exámenes patológicos revelan abscesos, necrosis y granulomas de tipo tuberculoide (3). La correlación clínica, biológica, patológica y, a veces, la progresión con el tratamiento antibacilar son la clave del diagnóstico 2

Cutaneous tuberculosis (TB) is a rare form of extrapulmonary tuberculosis that can have diverse clinical manifestations. Cutaneous involvement may occur as a result of exogenous inoculation, contiguous dissemination from a focus of infection, or by hematogenous spread from a distant focus (1). Multibacillary forms of cutaneous localization remain by far the most common in children (2). Children and the elderly are greatly affected due to immunological inability to contain the mycobacterial infection. Scrofuloderma can occur in isolation or coexist with pulmonary and disseminated forms of TB. It presents with erythematous nodules that fistulize and discharge caseous and purulent material (3). Anatomopathological examinations reveal abscesses, necrosis and tuberculoid granulomas (3). Clinical, biological, pathological correlation and sometimes progression with antibacillary treatment are the key to diagnosis (2)
