Caso de uma grávida com 38 anos, referenciada por ecocardiograma precoce (15 semanas) sugestivo de cardiopatia complexa parecendo tratar-se de truncus arteriosus com arco truncal direito. O teste genético de rastreio pré-natal não invasivo (NIPS) para as aneuploidias mais comuns havia dado um resultado considerado de baixo risco. Fez-se colheita de vilosidades coriónicas (BVC). O estudo por microarray é o teste genético recomendado nas gestações com anomalias ecográficas. Assim, pretende-se estabelecer uma relação causal entre as anomalias observadas no feto e uma alteração genética. N/A

Objective: The purpose of this study was to investigate the effects of different intervals between static stretching for hip adductor, quadriceps and hamstring muscles and resistance training in repetition performance. Method: Twenty-two trained men were submitted to the 10 repetition maximum test and retest for leg extension, leg curl and hip adduction exercises. Three protocols were conducted in a randomized design - PWI: resistance training immediately after static stretching; P15: fifteen-minute rest interval between static stretching and resistance training; P30: thirty-minute rest interval between static stretching and resistance training. Results: The total number of repetition [(sets*repetitions) + exercises] performed under P30 (84.55 ± 1.68) was significantly higher than P15 (79.73 ± 1.89) and PWI (68.09 ± 2.03), respectively. Significant differences were also found between P15 and P30. Conclusions: Therefore, 30-minute interval between static stretching and resistance exercises was needed to achieve greater repetition performance. Thus, static stretching for lower limbs may be avoided before a resistance training session. Resumen Objetivo: El objetivo de ese estudio fue investigar los efectos de distintas secuencias de estiramiento estático, en los músculos aductores de la cadera, cuádriceps e isquiotibiales y el entrenamiento de resistencia, en el rendimiento en repeticiones. Método: Veintidós hombres entrenados fueron sometidos a la prueba de 10 repeticiones máximas para ejercicios de extensión de piernas, flexión de piernas y aducción de cadera. Tres protocolos fueron realizados utilizando un diseño aleatorio: PSI: entrenamiento de resistencia realizado inmediatamente después del estiramiento estático; P15: intervalo de descanso de 15 minutos entre estiramiento estático y entrenamiento de resistencia; P30: intervalo de descanso de 30 minutos entre estiramiento estático y entrenamiento de resistencia. Resultados: El número total de repeticiones [(sets*repetición) + ejercicio], realizadas en P30 (84.55 ± 1.68) fue significativamente mayor que P15 (79.73 ± 1.89) y PSI (68.09 ± 2.03), respectivamente. También se observaron grandes diferencias entre P15 y P30. Conclusiones: Por lo tanto, se necesitó un intervalo de 30 minutos entre el estiramiento estático y los ejercicios de resistencia para lograr un mayor rendimiento en repeticiones. En este sentido, el estiramiento estático para miembros inferiores puede ser evitado antes de una sesión de entrenamiento de resistencia. Resumo Objetivo: O objetivo deste estudo foi investigar os efeitos de diferentes intervalos entre alongamento estático para os músculos adutores do quadril, quadríceps e isquiotibiais e o treinamento resistido no desempenho de repetições. Método: Vinte e dois homens treinados foram submetidos ao teste de 10 repetições máximas e reteste para os exercícios de extensão, e flexão de joelhos, e de adução do quadril. Três protocolos foram conduzidos em um desenho randomizado: PWI - treinamento resistido imediatamente após o alongamento estático; P15 - intervalo de descanso de 15 minutos entre alongamento estático e o treinamento resistido; P30 - intervalo de descanso de 30 minutos entre alongamento estático e o treinamento resistido. Resultados: O número total de repetição ([séries * repetições] + exercícios) realizada em P30 (84.55 ± 1.68) foi significativamente maior do que o P15 (79.73 ± 1.89) e PWI (68.09 ± 2.03), respectivamente. Diferenças significativas também foram encontradas entre P15 e P30. Conclusões: O intervalo de 30 minutos entre o alongamento estático e o exercício resistido foi necessário para alcançar maior desempenho no número de repetição. Assim, os alongamentos estáticos para membros inferiores podem ser evitados antes de uma sessão treinamento resistido.

Superior mesenteric vein aneurysms are an extremely rare clinical entity, with a variable clinical presentation and an unpredictable clinical course. The authors present the case of a 41 year old female with a saccular superior mesenteric vein aneurysm incidentally identified on abdominal CT scan. The patient was treated with surgical aneurismectomy with a vascular stapler, and the postoperative recovery was uneventful. She is clinically well two years after surgery. Os aneurismas da veia mesentérica superior são uma entidade clínica extremamente rara com uma apresentação clínica variável e um curso clínico difícil de prever. Os autores apresentam o caso clínico de uma doente de 41 anos a quem foi diagnosticado incidentalmente em TC abdominal um aneurisma sacular da veia mesentérica superior. A doente foi submetida a aneurismectomia com agrafadora vascular. O pós-operatório decorreu sem incidentes. A doente encontra-se clinicamente bem dois anos após a cirurgia.

As duplicações do tubo digestivo são malformações congénitas raras que podem ocorrer em qualquer porção do tubo digestivo e que se apresentam habitualmente na primeira década de vida. Um número limitado de casos só é diagnosticado na idade adulta. O íleum é a localização mais frequente e o cólon a menos frequente. A apresentação clínica no adulto é bastante variável e inespecífica. Os autores apresentam três casos de duplicações intestinais em doentes adultas do sexo feminino, correspondendo a duplicação gástrica, do cego e do cólon descendente. Os exames imagiológicos pré-operatórios identificaram a presença de lesões quísticas. A laparotomia fez o diagnóstico de duplicação intestinal e a opção cirúrgica consistiu em ressecção das lesões. A raridade destas malformações e em particular a sua apresentação na idade adulta levam-nos à apresentação destes casos juntamente com uma revisão da literatura publicada sobre o tema. Alimentary tract duplications are uncommon congenital anomalies. They can occur anywhere in the gastrointestinal tract and usually present during the first decade of life. However, a smaller number of cases may remain unsuspected until adulthood. They are most common in the ileum and least common in the colon. Clinical presentation in adults is variable and nonspecific. The authors report three cases of alimentary tract duplication in three adult females, affecting the stomach, the caecum and the descending colon. Pre-operative imagiologic workout revealed cystic lesions. All patients were submitted to exploratory laparotomy in which the diagnosis of duplication was confirmed and the surgical strategy consisted in excision of the lesions. The rarity of this entity and particularly it’s presentation in the adulthood made us to present this cases along with a review of the published literature on this subject.

The purpose of this study was to investigate the acute hormonal response to resistance training sessions with different volumes in men.Ten recreationally trained men (24.5±7.6 years; 76.2±9.2 kg; 175.6±1.5 cm; 24.5±5.5 kg/m(-2)) participated in the study. All subjects completed two experimental protocols with different volumes. The first protocol consisted of 3 sets at 80% of 6 RM and the second protocol was 3 sets at 80% of 12 RM with 2 minutes rest between sets and exercises, separated by seven days between them. The exercise order used was: barbell bench press, leg press, machine front lat-pull down, leg curl, shoulder abduction and leg extension. The blood variables analyzed were: testosterone, growth hormone (GH), cortisol and testosterone/cortisol ratio (T:C) before (Pre) and immediately after (Post) each exercise session.The intra-groups comparison for testosterone and hGH revealed a significant increase in 80%-6RM and 80%-12RM. Cortisol levels was significantly higher in 80%-12RM and T:C ratio in 80% 6 RM when compared Pre and Post values. Inter-groups comparison showed higher hGH and cortisol levels and lower T:C ratio for 80% 12 RM. There was no statistically significant different between 80%-6RM and 80%-12RM for testosterone.The present study confirms that the volume of resistance training can be an important factor in the modulation of acute hormonal responses.

The molecular mechanisms of plant recognition, colonization, and nutrient exchange between diazotrophic endophytes and plants are scarcely known. Herbaspirillum seropedicae is an endophytic bacterium capable of colonizing intercellular spaces of grasses such as rice and sugar cane. The genome of H. seropedicae strain SmR1 was sequenced and annotated by The Parana´ State Genome Programme?GENOPAR. The genome is composed of a circular chromosome of 5,513,887 bp and contains a total of 4,804 genes. The genome sequence revealed that H. seropedicae is a highly versatile microorganism with capacity to metabolize a wide range of carbon and nitrogen sources and with possession of four distinct terminal oxidases. The genome contains a multitude of protein secretion systems, including type I, type II, type III, type V, and type VI secretion systems, and type IV pili, suggesting a high potential to interact with host plants. H. seropedicae is able to synthesize indole acetic acid as reflected by the four IAA biosynthetic pathways present. A gene coding for ACC deaminase, which may be involved in modulating the associated plant ethylene-signaling pathway, is also present. Genes for hemagglutinins/ hemolysins/adhesins were found and may play a role in plant cell surface adhesion. These features may endow H. seropedicae with the ability to establish an endophytic life-style in a large number of plant species.

The purpose of this study was to investigate the influence of different resistance exercise orders on the number of repetitions performed to failure and on the ratings of perceived exertion (RPE) in trained women. Twenty-three women with a minimum of 2 years of resistance training experience volunteered to participate in the study (age, 24.2 +/- 4.5 years; weight, 56.9 +/- 4.7 kg; height, 162.3 +/- 5.9 cm; percent body fat, 18.2 +/- 2.9%; body mass index, 22.2 +/- 2 kg x m(-2)). Data were collected in 2 phases: (a) determination of a 1 repetition maximum (1RM) for the leg-press (LP), bench press (BP), leg extension (LE), seated machine shoulder press (SP), leg curl (LC), and seated machine triceps extension (TE); and (b) execution of 3 sets, with 2-minute rest intervals between sets and exercises, until fatigue using 80% of 1RM in 2 exercise sequences of the exact opposite order--Sequence A: BP, SP, TE, LP, LE, and LC, and Sequence B: LC, LE, LP, TE, SP, and BP. The RPE (Borg CR-10) was accessed immediately after each sequence and analyzed using a Wilcoxon test. A 2-way analysis of variance with repeated measurements, followed by a post hoc Fisher least significant difference test where indicated was used to analyze the number of repetitions per set of each exercise during the 2 sequences. The RPE was not significantly different between the sequences. The mean number of repetitions per set was always less when an exercise was performed later in the exercise sequence. The data indicate that in trained women, performance of both large- and small-muscle group exercises is affected by exercise sequence.
