ABSTRACT

El síndrome de cordón umbilical corto es una anomalía poco común e incompatible con la vida que se asocia a defectos de la pared anterior del feto, cordón umbilical corto o ausente y anomalías de los miembros. Esta entidad es la más severa y más infrecuente entre los defectos de la pared anterior del abdomen, con una incidencia de 1 en 14 000 nacimientos. Se presenta el caso de un recién nacido de término, de sexo indeterminado, producto de primer embarazo, de parto abdominal. A las 28 semanas de gestación se diagnosticó un defecto en pared abdominal anterior y una imagen quística de columna vertebral por ultrasonografía. Al nacimiento se observaron los órganos abdominales expuestos, el cordón umbilical grueso, de 10 cm de longitud, eventración de intestinos e hígado y cifoescoliosis marcada, ausencia de genitales externos y de ano, un remanente de miembro inferior derecho y miembro inferior izquierdo completo con pie equinovaro. Se le dio apoyo ventilatorio y falleció a los 15 minutos de vida


Short umbilical cord syndrome is a rare and life-incompatible abnormality associated with fetal anterior wall defects, absent or short umbilical cord, and limb abnormalities. This entity is the most severe and rarest of anterior abdominal wall defects, with an incidence of 1 in 14,000 births. We present the case of a full-term newborn, of undetermined sex, product of first pregnancy, of abdominal delivery. At 28 weeks' gestation, an anterior abdominal wall defect and a cystic image of the spine were diagnosed by ultrasonography. At birth, the exposed abdominal organs, the thick umbilical cord, 10 cm in length, eventration of the intestines and liver and marked kyphoscoliosis, absence of external genitalia and anus, a remnant of the right lower limb and complete left lower limb with foot were observed. equinovarus. Ventilatory support was given and died at 15 minutes of life

ABSTRACT

La malrotación intestinal es un espectro de malformaciones, que incluye una gran variedad de alteraciones en el proceso de rotación y fijación del intestino. La ausencia completa de rotación intestinal, uno de los tipos de malrotación intestinal más frecuentes, puede presentarse como hallazgo asintomático o manifestarse clínicamente por un vólvulo del intestino medio. Sin embargo, incluso entre aquellos que se presentan con vólvulo del intestino medio, la clínica puede ser muy diferente, según el grado de isquemia y eventual necrosis intestinal. Se presentan dos casos clínicos de malrotación intestinal con vólvulo del intestino medio con presentaciones, imágenes, tratamientos y evoluciones muy disímiles. Se analizan los mismos a la luz de una revisión bibliográfica relevante al tema tratado, se sacan aprendizajes del manejo realizado y la evolución que presentaron, y se enfatizan los elementos de mayor jerarquía para optimizar el manejo de estos pacientes.


Intestinal malrotation is a spectrum of malformations that includes a great variety of alterations in the rotation and fixation process of the intestines. The total absence of intestinal rotation, one of the most frequents types of intestinal malrotation could present as an asymptomatic find or appear clinically as a midgut volvulus. However, even those that appear as midgut volvulus, could show quite different signs and symptoms according to the degree of ischemic insult and possible intestinal necrosis. Two clinical cases of intestinal malrotation with midgut volvulus with quite different presentations, images, treatments, and evolutions, are informed. The two cases are analyzed under a relevant bibliographic revision, knowledge is derived from the carried-out management and evolution, and elements for the future optimization of management are underlined.


A má rotação intestinal é um espectro de malformações, que inclui uma grande variedade de alterações no processo de rotação e fixação do intestino. A ausência completa de rotação intestinal, um dos tipos mais comuns de má rotação intestinal, pode se apresentar como um achado assintomático ou manifestar-se clinicamente como um volvo de intestino médio. Porém, mesmo entre aqueles que apresentam volvo de intestino médio, os sintomas podem ser muito diferentes, dependendo do grau de isquemia e eventual necrose intestinal. Dois casos clínicos de má rotação intestinal com volvo de intestino médio são apresentados com apresentações, imagens, tratamentos e evoluções muito diferentes. São analisados ​​à luz de uma revisão bibliográfica pertinente ao tema em questão, lições aprendidas com o manejo realizado e a evolução que apresentaram, e os elementos de maior hierarquia são enfatizados para otimizar o manejo desses pacientes.

ABSTRACT

La falla intestinal secundaria a síndrome de intestino corto en pediatría es una entidad poco frecuente, de alta morbimortalidad. Requiere de un equipo interdisciplinario para su abordaje, lo cual ha demostrado que disminuye la morbimortalidad y aumenta la posibilidad de que los pacientes logren la autonomía intestinal. Existe una falta de evidencia científica en diferentes abordajes de la patología. Consideramos necesario el desarrollo de esta Guía para el Manejo Clínico construida sobre la base de la metodología Delphi modificada, en la Asociación Argentina de Nutrición Enteral y Parenteral, por 16 expertos que se reunieron para discutir y consensuar los principales aspectos de tratamiento clínico. Se analizaron 4 aspectos: definiciones y epidemiología; nutrición enteral, nutrición parenteral; tratamientos farmacológicos y quirúrgicos,y criterios de derivación a centros de alta complejidad. Sin duda este documento será de utilidad para los pacientes, los profesionales y las instituciones, así como para los diferentes financiadores del sistema de salud.


Intestinal failure secondary to short bowel syndrome in pediatrics, is a rare condition with high morbimortality. A follow up multidisciplinary team is necessary to minimize complications and optimize the intestinal rehabilitation. There are no gold standard guidelines for the management of this group of complex patients. The development of clinical guidelines may contribute for an adequate management of patients with intestinal failure and short bowel syndrome. This Clinical Guideline for the Management was developed by 16 experts based on modified Delphi methodology. The meetings were held at the Argentinian Association of Enteral and Parenteral Nutrition (Asociación Argentina de Nutrición Enteral y Parenteral); the topics analyzed were definitions, epidemiology, enteral and parenteral nutrition, pharmacological and surgical treatments, and criteria for referring patients to intestinal rehabilitation centers. The document is aimed to provide basic scientific knowledge for medical institutions, health providers, healthcare providers, patients and families.

ABSTRACT

OBJECTIVES: Ischemia and reperfusion (I/R) in the intestine could lead to severe endothelial injury, compromising intestinal motility. Reportedly, estradiol can control local and systemic inflammation induced by I/R injury. Thus, we investigated the effects of estradiol treatment on local repercussions in an intestinal I/R model. METHODS: Rats were subjected to ischemia via the occlusion of the superior mesenteric artery (45 min) followed by reperfusion (2h). Thirty minutes after ischemia induction (E30), 17β-estradiol (E2) was administered as a single dose (280 μg/kg, intravenous). Sham-operated animals were used as controls. RESULTS: I/R injury decreased intestinal motility and increased intestinal permeability, accompanied by reduced mesenteric endothelial nitric oxide synthase (eNOS) and endothelin (ET) protein expression. Additionally, the levels of serum injury markers and inflammatory mediators were elevated. Estradiol treatment improved intestinal motility, reduced intestinal permeability, and increased eNOS and ET expression. Levels of injury markers and inflammatory mediators were also reduced following estradiol treatment. CONCLUSION: Collectively, our findings indicate that estradiol treatment can modulate the deleterious intestinal effects of I/R injury. Thus, estradiol mediates the improvement in gut barrier functions and prevents intestinal dysfunction, which may reduce the systemic inflammatory response.

ABSTRACT

To study the effect of self-assembled nanoparticles from Shaoyao Gancao Decoction(SGD-SAN) on the encapsulation, in vitro release and intestinal absorption of the main components of Baishao. Particle size analysis and morphological observation were used to verify the formation of SGD-SAN in the decoction. The entrapment efficiency(EE) of SGD-SAN on the main components of Baishao was determined by ultrafiltration centrifugation. The dialysis bag method was used to study the in vitro release of the main components of Baishao with pH 6.8 phosphate buffer solution as the release media. Single-pass intestinal perfusion study was performed to investigate the effect of SGD-SAN on the absorption of the main components of Baishao. The results showed that there were nanoparticles in the SGD, and the particle sizes and PDI of SGD-SAN were about 200 nm and 0.38, respectively. SGD-SAN was irregularly spherical under transmission electron microscope(TEM). The EEs of albiflorin, paeoniflorin and benzoylpaeoniflorin in SGD-SAN were 33.78%±1.03%,33.61%±0.90%,88.53%±0.58%, respectively. The release characteristics of albiflorin, paeoniflorin and benzoylpaeoniflorin from SGD-SAN showed a slow-release effect on pH 6.8 phosphate buffer solution media. SGD-SAN could significantly enhance the absorption of albiflorin, paeoniflorin and benzoylpaeoniflorin in the ileum. The results of this study indicated that SAN could be formed during the mixed decoction of Baishao and Gancao, and SGD-SAN could encapsulate the components of Baishao, with a certain slow-release effect, and the formation of SAN facilitated the absorption of drugs in the ileum.

ABSTRACT

The present study is to investigate the absorption characteristics of the main components in Polygonum orientale extract in normal and isoproterenol-induced myocardial ischemia model rats with everted intestinal sac models. Intestinal sac fluid samples were collected in different part of intestine(duodenum, jejunum, ileum, colon) at different time after administration of different concentration of P. orientale extract(5.0,10.0, 20.0 mg·mL~(-1)). An UPLC-TQD method was employed for the determination of six components including orientin, isoorientin, vitexin, protocatechuic acid, kaempferol-3-O-β-D-glucoside and quercitrin in the intestinal sac samples. The absorption rate and cumulative absorption were calculated to analyze the intestinal absorption characteristics of six components in normal and myocardial ischemia model rats. The P-glycoprotein(P-gp) inhibitor was applied to investigate influence of intestinal absorption of six components in P. orientale extract. The results showed that the main absorption sites were concentrated on the duodenum at low concentration, while they were the colon at the medium concentration and the ileum at high concentration in control groups. In the condition of myocardial ischemia model, the main absorption sites focus on the ileum and jejunum at low concentration; the main absorption sites were in the ileum at the medium concentration and main absorption sites were the duodenum and ileum at high concentration. Compared with the normal group, the absorption rate and cumulative absorption of the six components significantly decreased in the model group. P-gp inhibitor markedly increased the absorption rate and cumulative absorption of six components in the model group, inferring that the 6 components may be the substrates of P-gp, and the mechanism needs further study. In this study, it is revealed that the six components of P. orientale extract can be absorbed into the intestinal sac, and it is an effective method to assess the intestinal absorption characteristics of P. orientale extract through everted intestinal sac model, providing data support for the clinical application and further development of P. orientale.

ABSTRACT

"Target fishing" strategy was used to investigate the direct targets and mechanism of Shouhui Tongbian Capsules on relaxing bowel. Magnetic beads cross-linked with the chemical constituents from Shouhui Tongbian Capsules were prepared. The potential target proteins were captured from the total protein lysates of rat intestine using the beads. The captured proteins were further identified by LC-MS/MS, and the associated pathways were analyzed by Cytoscape. RESULTS:: showed that 138 potential target proteins were identified, which were involved in eight signaling pathways, including tricarboxylic acid cycle, pyrimidine metabolism, sulfur metabolism, fatty acid degradation, alanine/aspartate/glutamate metabolism, arginine/proline metabolism, valine/leucine/isoleucine degradation, and β-alanine metabolism. Taken together, Shouhui Tongbian Capsules may exert relaxing bowel effect by acting on multiple signaling pathways to promote intestinal gurgling, inhibit inflammation, as well as improve intestinal barrier function, intestinal water secretion, and intestinal flora.

ABSTRACT

The aim of this study was to analyze the parasitological tests of a population at a public hospital in Maceió-AL. A descriptive study was made between January and July of 2015 analyzing the parasitological tests of a population at a public hospital in Maceió-AL. Variables such as gender, age, positive tests, protozoan species, helminths species and parasitic associations were analyzed. Out of 1.581 tests, 806 (51%) tested positive. Regarding gender, 535 (67%) were from women. Helminths were the most predominant infections (63.94%), compared to protozoans (36.06%). The Helminths with the highest number of infections were: Ascaris lumbricoides (93.23%), Trichuris trichiura (2.32%) and Enterobius vermicularis (1.26%). Among protozoans, Endolimax nana and Entamoeba coli corresponded to78.09% and 15.91% respectively. Although non pathogenic, it suggests fecal contamination. According to the degree of parasitism, 84.0% were monoparasitism. It can be concluded that the number of positive tests for enteroparasites was high, mainly in men. The species A. lumbricoides was the main helminth detected, while E. nana was the main protozoan found in the tests. The age group between 24 and 59 years old was the one that had the highest amount of positive tests. The results observed strengthen the need for the implementation of prevention measures for intestinal parasitic infections.


Os estudos da ocorrência de parasitoses em laboratório são de grande relevância, pois os mesmos podem proporcionar informações necessárias no diagnóstico da infecção e avaliar o índice de infecção parasitária, principalmente dos países em desenvolvimento, constituindo um problema de saúde pública. Foram coletados dados de exames de fezes realizados no período de janeiro a julho de 2015 nos registros de exames coproparasitológicos de fezes, de um hospital universitário de Maceió-AL. Foram analisados 1.581 exames, realizados pelo método de Hoffmann, Pons e Janer. Foi possível verificar que 51% apresentaram positividade para um ou mais enteroparasitos, sendo 66% para o sexo feminino e 34% no sexo masculino. Predominaram-se as infecções causadas por helmintos, com 55%, seguido das infecções causadas por protozoários 45%. Os helmintos com maior frequência de detecção foram: Ascaris lumbricoides (50,14%), Trichuris trichiura (1,61%), Enterobius vermicularis (0,87%) e ancilostomídeos (0,87%). Dentre os protozoários, Endolimax nanae Entamoeba coli com 34,42% e 7,8% respectivamente, que embora comensais indiquem contaminação fecal. A faixa etária entre 6 e 11 anos apresentou maior número de indivíduos parasitados (2,1%). Quanto ao grau de parasitismo, houve uma predominância de 84% para monoparasitismo. Assim, conclui-se, que foi elevado o número positividade para enteroparasitos, com predominância de casos no gênero masculino. A espécie A. lumbricoides foi e helminto detectado, enquanto que, E. nana foi o principal protozoário. A faixa etária entre 6 a 11 anos foi a que apresentou maior número de casos positivos. Os resultados observados reforçam a necessidade da implantação de medidas de prevenção para as parasitoses intestinais.

ABSTRACT

Introduction: The decreasing prevalence of parasitosis from north to south in Argentina has led the scientific community to focus the epidemiological studies on the most vulnerable areas and, consequently, neglect the populations of Patagonia (South Argentina). The objectives of the present study were (i) to determine the prevalence of intestinal parasites in children and youth of Puerto Madryn (Chubut province, Patagonia), and (ii) to evaluate the parasitic infections found concerning socio-environmental factors and hygiene practices of the population. Materials and methods: Serial stool samples were processed using modified Ritchie and FLOTAC dual pellet techniques, and samples of anal swabs were examined by sedimentation. Socio-environmental variables and hygiene practices of the participants were surveyed using a semi-structured questionnaire. Results: Of all examined participants, 39.1% (68/174) were parasitized. A total of 6 parasite species were found and the most prevalent were Blastocystis sp (19.0%), Enterobius vermicularis (17.8%), and Giardia lamblia (6.3%). The risk of parasitosis and infection for Blastocystis sp was greater in participants who lived in houses without piped water (OR = 2.9 and OR = 3.2, respectively). The risk of infection for G. lamblia was positively associated with the lack of public waste collection service (OR = 5.6). Infection for E. vermicularis was higher in participants whose parents had a basic level of education (OR = 5.0). Conclusion: The parasitic infections observed reflect the environmental conditions of Patagonia and the need to focus studies on populations from peripheral areas to urban centers that are exposed to greater socio-economic vulnerability.


Introducción: La prevalencia de parasitosis decreciente de norte a sur en la Argentina, ha llevado a la comunidad científica a enfocar sus estudios epidemiológicos hacia las zonas más vulnerables y desatender a las poblaciones de la Patagonia (sur de Argentina). Los objetivos del presente estudio fueron: determinar la prevalencia de parásitos intestinales en niños y jóvenes de Puerto Madryn (Chubut, Patagonia), y evaluar las infecciones parasitarias en relación con los factores socioambientales y las prácticas de higiene de la población. Materiales y métodos: Se procesaron muestras seriadas de materia fecal mediante las técnicas Ritchie modificada y FLOTAC dual pellet, y muestras de escobillado anal por sedimentación. Se relevaron las variables socioambientales y las prácticas de higiene de los participantes mediante cuestionarios semiestructurados. Resultados: El 39.1% (68/174) de la población analizada estuvo parasitado. Se halló un total de 6 especies parásitas, las más prevalentes de las cuales fueron Blastocystis sp (19.0%), Enterobius vermicularis (17.8%) y Giardia lamblia (6.3%). El riesgo de parasitosis y de infección por Blastocystis sp fue mayor en los participantes que no poseían agua de red (odds ratio [OR] = 2.9 y OR = 3.2, respectivamente). La infección por G. lamblia se asoció de manera positiva con la falta de recolección pública de residuos (OR = 5.6). La infección por E. vermicularis fue superior en los participantes con padres que tenían un nivel de estudios primario (OR = 5.0). Conclusión: Las infecciones parasitarias observadas reflejan las condiciones ambientales de la Patagonia y la necesidad de orientar los estudios a poblaciones periféricas de los centros urbanos, las cuales están expuestas a mayor vulnerabilidad socioeconómica

ABSTRACT

Given the importance of the Golden kingklip (Genypterus blacodes) as an alternative to the production of salmonid species for worldwide diversification of aquaculture this study researched the morpho-histology of the digestive canal, providing a uniform nomenclature and basic information to support their nutritional management in captive conditions. The objective was to describe the normal morphology of the digestive canal. Twelve wild specimens were collected and dissected. Samples of the esophagus, stomach, liver, pyloric blind and intestines were obtained. An anatomical and histological description was performed. The digestive canal presented a short tubular esophagus, a slightly dilated, J-shaped stomach and thick walls. The stomach had a cardiac region that ended in a pyloric sphincter from which the intestine of thin walls. The intestine presented an anterior, middle and posterior segment. The anterior region of the first segment of the middle intestine presented 4-5 pairs of pyloric cecum. The middle intestine represented approximately 30 % of the total length of the digestive canal, with a smaller diameter compared to the first segment. The posterior intestine was separated from the middle intestine by a thick and powerful sphincter. The liver was large and elongated, and located in the peritoneal cavity located to the left plane and ventral to the swim bladder. The gallbladder was located lateral to the hepatic anterior wolf. The bile duct led to the duodenal region of the anterior intestine. Ventrally, the rectum ended in the anus, located in front of the anal fin. In general, the histological structures were variable according to the segment studied, a mucous tunic was recognized that presented a simple columnar epithelium, a lamina propria composed of loose connective tissue, a muscular layer of the mucosa composed of smooth muscle tissue and a submucosal layer composed of loose connective tissue, a circular and longitudinal stratum of muscular tunic, which had striated musculature and an adventitial tunic composed of a simple squamous epithelium. In conclusion, Golden kingklip (Genypterus blacodes) presents a digestive system typical of a carnivorous benthic fish adapted to feed on fish and crustaceans.


Dada la importancia del Congrio colorado (Genypterus blacodes) como alternativa a la producción de especies salmonídeas para la diversificación mundial de la acuicultura, el objetivo del presente estudio es describir la morfología normal del canal digestivo de esta especie, proporcionando una nomenclatura uniforme e información básica para apoyar su manejo nutricional en condiciones de cautiverio. Doce especímenes silvestres fueron colectados y disecados. Se obtuvo muestras del esófago, estómago, hígado, ciego pilórico e intestinos. Se realizó una descripción anatómica e histológica. El canal digestivo presentó un esófago tubular corto, un estómago ligeramente dilatado, con forma de J y paredes gruesas. El estómago presentaba una región cardíaca que terminaba en un esfínter pilórico desde el cual el intestino de paredes delgadas. El intestino presentaba un segmento anterior, medio y posterior. La región anterior del primer segmento del intestino medio presentó 4-5 pares de ciegos pilóricos. El intestino medio representó aproximadamente el 30 % de la longitud total del canal digestivo, con un diámetro menor en comparación con el primer segmento. El intestino posterior estaba separado del intestino medio por un esfínter grueso y poderoso. El hígado era grande y alargado, y ubicado en la cavidad peritoneal ubicado al plano izquierdo y ventral a la vejiga natatoria. La vesícula biliar se ubicó lateral al lobo anterior hepático. El ducto biliar desembocó en la región duodenal del intestino anterior. Ventralmente, el recto terminó en el ano, ubicado frente a la aleta anal. En general, las estructuras histológicas fueron variables según el segmento estudiado, se reconoció una túnica mucosa que presentaba un epitelio columnar simple, una lámina propia de la mucosa compuesta por tejido conectivo laxo, una capa muscular de la mucosa compuesta por músculo liso tejido y una capa submucosa compuesta de tejido conectivo laxo, un estrato circular y longitudinal de túnica muscular, que tenía musculatura estriada y una túnica adventicia compuesta por un epitelio plano simple. En conclusión, Congrio colorado (Genypterus blacodes) presenta un sistema digestivo típico de un pez bentónico carnívoro adaptado para alimentarse de peces y crustáceos.

ABSTRACT

ABSTRACT BACKGROUND: Intestinal constipation (IC) in patients with the digestive form of Chagas disease is one of the main reasons for seeking medical care. Population data indicate that the practice of physical activity improves gastrointestinal motility. OBJECTIVE: This study evaluated the bowel frequency and symptoms of constipation and their relationship with the level of physical activity in patients with and without Chagas disease. METHODS: Patients (n=120) of both genres, aged between 35 and 84 years, in which 50% (n=60) were in the Chagas group and 50% (n=60) were in the control group, were evaluated regarding the level of IC using the Constipation Assessment Scale (CAS) and regarding the level of physical activity using the International Physical Activity Questionnaire (IPAQ). RESULTS - Patients in the Chagas group classified as active (IPAQ 2) had higher proportion (P=0.0235) of moderate IC with severe abdominal distension (P=0.0159) and decreased evacuation frequency (P=0.0281) than the patients in the control group, considered to be very active (IPAQ 1). The sedentary lifestyle was greater (P=0.0051) in the Chagas group with duration, intensity and frequency of physical activity lower than the control group. The health perception in the Chagas group was regular for 46.7% (P=0.0035) and poor for 8.3% (P=0.0244). CONCLUSION: There is a lower risk of developing intestinal constipation in more active individuals, evidencing that the level of physical activity interferes with bowel frequency and symptoms of constipation in patients with and without Chagas disease. The level of physical activity and health perception were worse in the Chagas group, reinforcing the disease stigma, which should be modified by the training of health professionals who routinely attend these patients.


RESUMO CONTEXTO: A constipação intestinal (CI) em pacientes com a forma digestiva da doença de Chagas é uma das principais razões para procura de atendimento médico. Os dados populacionais indicam que a prática de atividade física melhora a motilidade gastrointestinal. OBJETIVO: Este estudo avaliou a frequência intestinal e os sintomas de constipação e sua relação com o nível de atividade física em pacientes com e sem doença de Chagas. MÉTODOS: Pacientes (n=120) de ambos os gêneros, com idades entre 35 e 84 anos, nos quais 50% (n=60) eram do grupo Chagas e 50% (n=60) do grupo controle, foram avaliados quanto ao nível da CI utilizando a Escala de Avaliação da Constipação (CAS) e o nível de atividade física utilizando o Questionário Internacional de Atividade Física (IPAQ). RESULTADOS: Os pacientes do grupo Chagas classificados como ativos (IPAQ 2) apresentaram maior proporção (P=0,0235) de CI moderada com distensão abdominal grave (P=0,0159) e frequência de evacuação diminuída (P=0,0281) do que os pacientes do grupo controle, considerados muito ativos (IPAQ 1). O estilo de vida sedentário foi maior (P=0,0051) no grupo Chagas com duração, intensidade e frequência de atividade física menor que o grupo controle. A percepção de saúde no grupo Chagas foi regular para 46,7% (P=0,0035) e ruim para 8,3% (P=0,0244). CONCLUSÃO: Existe menor risco de desenvolver constipação intestinal em indivíduos mais ativos, evidenciando que o nível de atividade física interfere na frequência intestinal e nos sintomas de constipação em pacientes com e sem doença de Chagas. O nível de atividade física e percepção de saúde foram piores no grupo Chagas, reforçando o estigma da doença, que deve ser modificado pela capacitação dos profissionais de saúde que atendem rotineiramente esses pacientes.

ABSTRACT

The aim of this study was to evaluate in vitro the probiotic potential and absorption of Saccharomyces cerevisiae for the aflatoxin B1 in simulated fish intestinal tract conditions. Three yeast strains were used, two from brewery: S. cerevisiae RC1 and S. cerevisiae RC3 and one from a fish farming environment: S. cerevisiae A8L2. The selected yeasts were subjected to the following in vitro tests: homologous inhibition, self-aggregation, co-aggregation, antibacterial activity, gastrointestinal conditions tolerance and adsorption of AFB1. All S. cerevisiae strains showed good capability of self-aggregation and co-aggregation with pathogenic bacteria. All yeast strains were able to survive the gastrointestinal conditions. In acidic conditions, the factors (strain vs. time) had interaction (P=0.0317), resulting in significant variation among the strains tested in the time periods analyzed. It was observed that there was also interaction (P=0.0062) in intestinal conditions, with an increased number of cells in the 12-hour period for all strains tested. In the adsorption test, the A8L2 strain was statistically more effective (P<0.005) for both AFB1 concentrations evaluated in this study (10 and 25ng/mL). Thus, it was observed that the strains of S. cerevisiae have potential probiotic and adsorbent of AFB1.(AU)


Objetivou-se, com esta pesquisa, avaliar in vitro o potencial probiótico e adsorvente de Saccharomyces cerevisiae para aflatoxina B1 em condições simuladas do trato intestinal de peixes. Foram utilizadas três cepas de leveduras, sendo duas provenientes de cervejaria: S. cerevisiae RC1 e S. cerevisiae RC3, e uma de ambiente de piscicultura: S. cerevisiae A8L2. As leveduras selecionadas foram submetidas aos seguintes testes in vitro: inibição homóloga, autoagregação, coagregação, atividade antibacteriana, viabilidade às condições gastrointestinais e adsorção de AFB1. Todas as estirpes de S. cerevisiae mostraram boa capacidade de autoagregação e coagregação com bactérias patogênicas. Todas as estirpes de levedura foram capazes de sobreviver às condições gastrointestinais. Em condições ácidas, os fatores (cepa x tempo) tiveram interação (P=0,0317), resultando em variações significativas entre as cepas testadas nos períodos de tempo analisados. Observou-se que também houve interação (P=0,0062) em condições intestinais, havendo um aumento do número de células no período de 12h para todas as cepas avaliadas. No ensaio de adsorção, a estirpe A8L2 foi a mais eficaz estatisticamente (P<0,005), para as duas concentrações de AFB1 avaliadas neste estudo (10 e 25ng. mL-1). Dessa forma, conclui-se que as cepas de Saccharomyces cerevisiae possuem potencial probiótico e adsorvente de AFB1.(AU)

This study aimed to develop a guideline concerning the care directed toward an individual with an intestinal and/or urinary ostomy attending the Assistance Service for Ostomized Patients implemented at the Clinical Hospital of Uberlândia UFU, in order that such individuals be provided the means of self-care and thus improve their life quality. A bibliographical survey was performed on the theme, which focused on Guidelines Based on Evidence. The development of these guidelines was based on a bibliographical survey and took as its foundation the principles of Orem's self-care theory and the educational practices applied to pedagogy in health according to Paulo Freire's philosophy concerning liberating education, qualification and dialogue between the subject and the professional, which grants the possibility of aiding the family and patient to modify their lifestyles and be the agents of transformation, thus favoring the development of their autonomy. The printed educational material brings new information and knowledge to the ostomized patient.

ABSTRACT

Cystic fibrosis (CF) is an autosomal recessive disease caused by mutations in the gene encoding the cystic fibrosis transmembrane conductance regulator (CFTR). These mutations alter the synthesis, processing, function, or half-life of CFTR, the main chloride channel expressed in the apical membrane of epithelial cells in the airway, intestine, pancreas, and reproductive tract. Lung disease is the most critical manifestation of CF. It is characterized by airway obstruction, infection, and inflammation that lead to fatal tissue destruction, which causes most CF morbidity and mortality. This article reviews the pathophysiology of CF, recent animal models, and current treatment of CF.

ABSTRACT

BACKGROUND Visceral leishmaniasis (VL) is a tropical neglected disease with high associated rates of mortality. Several studies have highlighted the importance of the intestinal tract (IT) and gut microbiota (GM) in the host immunological defense. Data in the literature on parasite life cycle and host immune defense against VL are scarce regarding the effects of infection on the IT and GM. OBJECTIVES This study aimed to investigate changes observed in the colon of Leishmania infantum-infected hamsters, including alterations in the enteric nervous system (ENS) and GM (specifically, levels of bifidobacteria and lactobacilli). METHODS Male hamsters were inoculated with L. infantum and euthanised at four or eight months post-infection. Intestines were processed for histological analysis and GM analysis. Quantitative polymerase chain reaction (qPCR) was performed to quantify each group of bacteria: Bifidobacterium spp. (Bf) and Lactobacillus spp (LacB). FINDINGS Infected hamsters showed histoarchitectural loss in the colon wall, with increased thickness in the submucosa and the mucosa layer, as well as greater numbers of intraepithelial lymphocytes. Forms suggestive of amastigotes were seen inside mononuclear cells. L. infantum infection induced changes in ENS, as evidenced by increases in the area of colonic enteric ganglia. Despite the absence of changes in the levels of Bf and LacB during the course of infection, the relative abundance of these bacteria was associated with parasite load and histological alterations. MAIN CONCLUSIONS Our results indicate that L. infantum infection leads to important changes in the colon and suggest that bacteria in the GM play a protective role.

ABSTRACT

PURPOSE: Alterations in the intestinal microbiota in early life affects the development of atopic dermatitis (AD) in humans. This study aimed to further investigate the effects of gut dysbiosis in early life in an ovalbumin (OVA)-induced mouse model of AD. METHODS: The AD mouse model was developed by serial OVA sensitization and mice were treated with an antibiotic cocktail in their drinking water for 2 weeks before primary sensitization. Probiotics (Lactobacillus rhamnosus, 1 × 10⁹ CFU) or 100 µL of fresh fecal supernatant were orally administered daily from 1 week before the first sensitization until the end of the study. RESULTS: The AD mice which received antibiotics had significantly aggravated phenotypes, including clinical score, transepidermal water loss, and histopathology, compared to those treated with healthy feces or probiotics. Total systemic immunoglobulin E production and skin interleukin (IL) 4 levels were significantly increased in the antibiotic-treated mice compared to the other groups. Antibiotic treatment also increased the levels of IL17 and group 3 innate lymphoid cells (ILC3) in the gut and significantly suppressed the production of short-chain fatty acids (SCFAs) and decreased the number FOXP3⁺ cells. CONCLUSIONS: Our results suggest that the status of the gut microbiota in early life in the mouse may play a crucial role in AD development through intestinal SCFA production through regulate the numbers of CD4⁺IL17⁺/CD4⁺FOXP3⁺ regulatory T cells and ILC3s.

ABSTRACT

ABSTRACT Background: The use of probiotics positively modifies the composition and function of intestinal flora, improving the quality of intestinal anastomosis. Aim: To evaluate the impact of probiotic use on intestinal anastomosis of rats. Method: Thirty-six adult male Wistar rats (Rattus norvegicus albinus, Rodentia Mammalia) were used, with body weight ranging from 220-320 g. The animals were housed and acclimated individually in boxes receiving water and ration ad libitum. After initial acclimatization, the control group received perioperative ration ad libitum for 12 days (seven preoperatively and five postoperatively) associated with the maltodextrin formula at a dose of 250 mg/day in isocaloric and isovolumetric form. Likewise, the probiotic group received oral supplementation of probiotics dose of 250 mg/day, associated with isocaloric and isovolumetric diet. The probiotic chosen for this study was composed of strains (doses 1x109 CFU/g)12 Lactobacillus paracasei LPC-37, Bifidobacterium lactis HN0019, Lactobacillus rhamnosus HN001 and Lactobacillus acidophilus NCFM. Probiotics or placebo were administered orally with the aid of a dosimeter spatula. Both groups underwent two colostomies, one in the right colon and the second in rectosigmoid, followed by reanastomosis with eight separate 6-0 mononylon stitches. The sacrifice took place on the fifth day. The parameters evaluated included tensile strength, histology and collagen densitometry. Results: The rate of intestinal fistula for the control and probiotic groups were, respectively, 22.22% and 11.11% (p=0.6581).Perioperative supplementation with probiotics increased collagen deposition of types I and III (p<0.0001), improved maximum traction force and maximum rupture force, p=0.0250 and p=0.0116 respectively, fibrosis area (p<0.0001), and area of the inflammatory infiltrate (p=0.0115). Conclusions: The use of probiotics had a positive impact on the quality of intestinal anastomosis.


RESUMO Racional: A utilização de probióticos modifica positivamente a composição e função da flora intestinal melhorando a qualidade da anastomose intestinal. Objetivo: Avaliar o impacto da utilização de probióticos na anastomose intestinal de ratos. Método: Foram utilizados 36 ratos Wistar (Rattus norvegicus albinus, Rodentia Mammalia), machos adultos, com peso corporal variando entre 220 e 320 g. Os animais foram alojados e aclimatados individualmente em caixas recebendo água e ração ad libitum. Após aclimatação inicial, o grupo controle recebeu perioperatoriamente ração ad libitum por 12 dias (sete no pré-operatório e cinco no pós-operatório) associado à fórmula de maltodextrina na dose de 250 mg/dia de forma isocalórica e isovolumétrica. Na semana que precedeu o procedimento cirúrgico (período de sete dias) e no pós-operatório (por cinco dias), os ratos do grupo estudo receberam suplementação via oral de probióticos dose de 250 mg/dia, associado à dieta isocalórica e isovolumétrica. O probiótico utilizado era composto pelas cepas (doses 1x109 UFC/g)12 Lactobacillus paracasei LPC-37, Bifidobacterium lactis HN0019, Lactobacillus rhamnosus HN001 e Lactobacillus acidophilus NCFM. A administração de probiótico ou placebo foi realizada via oral, com auxílio de espátula com dosímetro. Os dois grupos foram submetidos à duas colostomias, uma em cólon direito e outra em retossigmóide, seguido de reanastomose com oito pontos separados de mononylon 6-0. O sacrifício ocorreu no quinto dia. Os parâmetros avaliados incluíram força tênsil, histologia e densitometria do colágeno. Resultados: A taxa de fístula intestinal para os grupos controle e probiótico foram, respectivamente, 22,22% e 11,11% (p=0.6581). A suplementação peroperatória com probióticos aumentou a deposição de colágeno dos tipos I e III (p<0.0001), melhorou a força máxima de tração e força máxima de ruptura, p=0,0250 e p= 0,0116 respectivamente, área de fibrose (p<0.0001), e área do infiltrado inflamatório (p=0.0115). Conclusões: A utilização de probióticos impactou positivamente na qualidade da anastomose intestinal.

ABSTRACT

ABSTRACT Background: Intestinal diversions have revolutionized the treatment of morbid obesity due to its viability and sustained response. However, experimental studies suggest, after these derivations, a higher risk of colon cancer. Aim: To analyze the histological and immunohistological changes that the jejunojejunal shunt can produce in the jejunum, ileum and ascending colon. Method: Twenty-four male Wistar rats were randomly divided into two groups, control (n=12) and experiment (n=12) and subdivided into groups of four. Nine weeks after the jejunojejunal shunt, segmental resection of the excluded jejunum, terminal ileum and ascending colon was performed. Histological analysis focused on the thickness of the mucosa, height of the villi, depth of the crypts and immunohistochemistry in the expression of Ki-67 and p53. Results: Significant differences were found between the experiment and control groups in relation to the thickness of the mucosa in the jejunum (p=0.011), in the ileum (p<0.001) and in the colon (p=0.027). There was also a significant difference in relation to the height of the villus in the ileum (p<0.001) and the depth of the crypts in the jejunum (p0.001). The results indicated that there is a significant difference between the groups regarding the expression of Ki-67 in the colon (p<0.001). No significant differences were found between the groups regarding the expression of Ki-67 in the jejunum and ileum. In the P53 evaluation, negative nuclear staining was found in all cases. Conclusion: The jejunojejunal deviation performed in the Roux-in-Y gastrojejunal bypass, predispose epithelial proliferative effects, causing an increase in the thickness of the mucosa, height of the villi and depth of the crypts of the jejunum, ileum and ascending colon.


RESUMO Racional: As derivações intestinais revolucionaram o tratamento da obesidade mórbida pela sua viabilidade e resposta sustentada. Porém, estudos experimentais sugerem, após estas derivações, risco maior de câncer de cólon. Objetivo: Analisar as alterações histológicas e imunoistológicas que a derivação jejunojejunal possa produzir no jejuno, íleo e cólon ascendente. Método: Foram utilizados 24 ratos Wistar machos randomicamente divididos em dois grupos, controle (n=12) e experimento (n=12) e subdivididos em grupos de quatro. Nove semanas após a derivação jejunojejunal procedeu-se a ressecção segmentar do jejuno excluso, íleo terminal e cólon ascendente. Análise histológica focou na espessura da mucosa, altura dos vilos, profundidade das criptas e a imunoistoquímica na expressão do Ki-67 e p53. Resultados: Foram encontradas diferenças significativas entre os grupos experimento e controle em relação à espessura da mucosa no jejuno (p=0,011), no íleo (p<0,001) e no cólon (p=0,027). Também houve diferença significativa em relação à altura dos vilos no íleo (p<0,001) e profundidade das criptas no jejuno (p<0,001). Os resultados indicaram que existe diferença significativa entre os grupos em relação à expressão do Ki-67 no cólon (p<0,001). Não foram encontradas diferenças significativas entre os grupos em relação à expressão do Ki-67 no jejuno e no íleo. Na avaliação do P53, foi encontrada coloração nuclear negativa em todos os casos. Conclusão: O desvio realizado na derivação gastrojejunal em Y-de-Roux, predispõem efeitos proliferativos epiteliais, causando aumento da espessura da mucosa, altura dos vilos e profundidade das criptas do jejuno, íleo e cólon ascendente.

ABSTRACT

Since drug-resistant nematodes became a common problem in sheep and goat industries, alternative methods using natural products have emerged as a viable and sustainable anthelmintic treatment option. Here, the in vitro effect of essential oil extracted from Lippia gracilis Schauer was assessed on the hatching process of nematodes recovered from naturally infected goats. Essential oil at concentrations of 0.08% (0.008 µL/mL), 0.12% (0.012 µL/mL), and 0.16% (0.016 µL/mL) was able to induce an average inhibition of 74.7, 84 and 93%, respectively. The effective concentration required to inhibit egg hatching in 50% of eggs (EC50) was 0.03452%. Therefore, essential oil of L. gracilis showed promisor in vitro anthelmintic results against egg-hatching of goat gastrointestinal nematodes.(AU)


Como os nematoides resistentes a drogas se tornaram um problema comum nas indústrias de ovinos e caprinos, métodos alternativos que utilizam produtos naturais surgiram como uma opção de tratamento anti-helmíntico viável e sustentável. Aqui, o efeito in vitro do óleo essencial extraído de Lippia gracilis Schauer foi avaliado no processo de eclosão de nematoides recuperados de caprinos naturalmente infectadas. O óleo essencial nas concentrações de 0,08% (0,008 µL/mL), 0,12% (0,012 µL/mL), e 0,16% (0,016 µL/mL)foi capaz de induzir uma inibição média de 74,7, 84 e 93%, respectivamente. A concentração efetiva necessária para inibir a eclosão de ovos em 50% dos ovos (CE50) foi de 0,03452%. Portanto, o óleo essencial de L. gracilis apresentou resultados anti-helmínticos in vitro promissores contra a eclosão de nematódeos gastrintestinais de caprinos.(AU)
