ABSTRACT Introduction: Distension of the rectum wall and subsequent momentary relaxation of the internal anal sphincter (IAS) trigger a reflex called the rectoanal inhibitory reflex (RAIR). This same rectal distension causes a reflex contraction of the external anal sphincter (EAS), responsible for conscious continence called rectoanal excitatory reflex (RAER). This set of reflexes are named sampling reflex. Objectives: The sampling reflex is necessary to initiate defecation or flatulence. The objective of this study is to evaluate the sampling reflex and its practical applicability as a manometric marker of the main defecation disorders. Methodology: This review followed the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) items. The development method consisted of searching for articles in the research platforms BVS, PubMed, Cochrane Library, SciELO and ScienceDirect and for the selection of articles the Rayyan Platform was used. The articles resulting from the search strategies were added to the platform and five collaborators were invited for the blind selection. Finally, 6 articles were included in the final review. Results: An intact sampling reflex allows the individual to facilitate discrimination between flatus and stool and to choose whether to discharge or retain rectal contents. On the other hand, an impaired sampling reflex can predispose an individual to incontinence. Therefore, it was observed that patients with defecation disorders had an impaired sampling reflex, since it was found that constipated patients have incomplete opening of the IAS, lower amplitude of RAIR and increase of RAER. Most incontinent patients present a failure in the recruitment of the EAS, a decrease in the RAER and an increase in the RAIR, in duration and amplitude.

ABSTRACT Purpose: To evaluate the viability of the porcine vas deferens as a realistic microsurgical training model for vasectomy reversal Methods: The model uses swine testicles (vas deferent), which are usually discarded in large street markets since they are not part of Brazilian cuisine. The spermatic cord was carefully dissected, and the vas deferens were isolated, measuring 10 cm in length. A paper quadrilateral with 5 cm2 was built to delimit the surgical training field. The objective of the model is to simulate only the microsurgical step when the vas deferens are already isolated. The parameters analyzed were: feasibility for reproducing the technique, patency before and after performing the vasovasostomy, cost of the model, ease of acquisition, ease of handling, execution time, and model reproducibility. Results: The simulator presented low cost. All models made were viable with a texture similar to human, with positive patency obtained in 100% of the procedures. The internal and external diameters of the vas deferens varied between 0.2-0.4 mm and 2-3 mm, respectively, with a mean length of 9 ± 1.2 cm. The total procedure time was 43.28 ± 3.22 minutes. Conclusions: The realistic model presented proved to be viable for carrying out vasectomy reversal training, due to its low cost, easy acquisition, and easy handling, and providing similar tissue characteristics to humans.

RESUMO O óleo de Caryocar villosum é usado na medicina popular amazônica para tratar dores e condições inflamatórias. Assim, avaliamos as propriedades antiinflamatórias e antinociceptivas do extrato etanólico obtido das cascas dos frutos desta espécie. Os testes de contorções induzidas por ácido acético, hiperalgesia mecânica induzida por carragenina, formalina, edema de pata induzido por carragenina e peritonite induzida por carragenina foram usados em camundongos. O extrato etanólico de C. villosum obtido das cascas dos frutos inibiu significativamente o número de contorções abdominais, a hiperalgesia mecânica e o tempo de lambida da pata na segunda fase do teste de formalina. Na dose de 300 mg kg-1, o extrato também reduziu significativamente o volume de edema formado na fase tardia e reduziu o recrutamento de leucócitos e neutrófilos na cavidade peritoneal, bem como os níveis de quimiocina CXCL1. Sugere-se que o extrato atenua o recrutamento de leucócitos por meio da inibição da ativação de CXCL1. A atividade antinociceptiva periférica ocorre por meio da modulação da via opioide pois o pré-tratamento com o extrato etanólico de C. villosum reverteu a antinocicepção induzida pela naltrexona.

ABSTRACT The oil of Caryocar villosum is used in Amazonian folk medicine to treat pain and inflammatory conditions. So, we assessed the anti-inflammatory and antinociceptive properties of the ethanolic extract obtained from the fruit peels of this species. The acetic acid-induced writhing, carrageenan-induced mechanical hyperalgesia, formalin, carrageenan-induced paw edema and carrageenan-induced peritonitis tests were used on mice. The C. villosum ethanolic extract significantly inhibited the number of abdominal writhes, mechanical hyperalgesia and paw licking time in the second phase of the formalin test. At a dose of 300 mg kg-1, the extract also significantly reduced the volume of edema formed in the late phase and reduced the recruitment of leukocytes and neutrophils in the peritoneal cavity, as well as CXCL1 chemokine levels. It is suggested that the extract attenuates the leukocyte recruitment by inhibiting the CXCL1 activation. The peripheral antinociceptive activity occured through opioid pathway modulation because pretreatment with C. villosum ethanolic extract reversed the naltrexone-induced antinociception.

ABSTRACT Introduction: One of the most critical complications in myelodysplastic syndromes (MDS) is the progression to acute myeloid leukemia (AML). The dynamics of clonal evolution in MDS and how acquired mutations can be used as biomarkers to track disease progression remains under investigation. Objective and method: Herein, we investigated the frequency of common myeloid clonal mutations (FLT3, NPM1, JAK2, IDH1 and IDH2) in 88 patients with MDS and 35 AML patients with myelodysplasia-related changes, followed at a single reference center in northeastern Brazil. Results: Overall, 9/88 (10%) ofthe MDSpatients and 9/35 (26%) of the secondary AML patients had at least one mutation. While the JAK2 V617F mutation was the most frequent in the MDS patients, the FLT3, NPM1, IDH1 and IDH2 mutations were more frequently found in the secondary AML group. Furthermore, there was a higher frequency of FLT3, NPM1, IDH1 and IDH2 mutations in MDS patients classified as high-risk subtypes than in those of lower risk. Conclusion: Despite the limited sample size, our data suggest that mutations in FLT3, NPM1, IDH1 and IDH2 genes could be potential biomarkers to detect early disease progression in MDS.

Abstract Endozoochory refers to the ingestion of fruits by animals and their release through faeces as it plays an important role in maintaining ecosystems. This study aimed to evaluate the effect of cumbaru fruit ingestion by tapirs on cumbaru seed germination. In latrines, fruits ingested and excreted by the animals were collected among tapir faeces. The collected material was taken to the laboratory and placed in a germination chamber and greenhouse. Fruit ingestion and its subsequent defection propitiated a higher germination rate and germination vigor compared to non-ingested fruit grown in a germination chamber and greenhouse. The results in the greenhouse showed that the latrines (decomposing organic matter) have different thermal conditions (higher temperature), in relation to the external environment, which probably accelerated the germination processes. Evaluation of seedlings grown in a greenhouse and germination chamber indicated that growth in the greenhouse was better due to humic and fulvic acids, which are common stimulants of seed germination and seedling growth. Therefore, tapirs can be considered good fruit dispersers and inducers of cumbaru seeds germination.

Objective. Propose a list of congenital anomalies with corresponding codes in the tenth revision of the International Classification of Diseases (ICD), aiming at application in the scope of health surveillance. Methods. In December 2019, the following sources were searched: ICD-10, ICD-11, abnormalities monitored by three surveillance programs, and a database of rare diseases (Orphanet). The Abnormalities were extracted from these data sources, processed based on the ICD-10 and compiled with manual review. Results. 898 codes were identified, of which 619 (68.3%) were in Chapter XVII of ICD-10. Of the 279 codes in other chapters, 19 were exclusive of the ICD-11 search, 72 of the surveillance programs, 79 of the Orphanet and 36 of the ICD-10 search for terms. Conclusion. The codes contained in chapter XVII of ICD-10 do not capture the totality of congenital anomalies, indicating the need of adopting of an expanded list.

Abstract Knowledge of environmental conditions for seed germination and seedling formation of forest species is essential. The objective of this work is to evaluate the germination of Callisthene major seeds under laboratory conditions using six different temperatures (20, 25, 30, 35, 20-30 and 25-35 °C) and germitest paper (on and between paper). A completely randomized design was used with four replicates of 25 seeds per experimental unit. The variables evaluated were germination (%), germination speed index (GSI), average germination time (AGT) in days and normal seedlings. The results indicated that the species has a high germination index (above 94%) for all tested substrates and temperatures; however, the highest germination vigor (GSI and AGT) was obtained by alternating the temperature between 25-35 °C with the substrate on paper.

Abstract Paper aims To shed light on how knowledge is shared between companies during a collaborative new product development (NPD) process. Originality It is the first study of different knowledge sharing levels for each stage of the NPD process in an inter-organizational context. Research method A research framework was created based on the literature. Guided by this framework, an in-depth case study was performed in a multinational company analyzing the knowledge sharing with the company’s supplier during a collaborative NPD process. Main findings Different levels of knowledge sharing were found at each stage of the NPD process. Implications for theory and practice The results complement previous works demonstrating that this phenomenon should not be considered as a binary state. By clearly presenting how knowledge sharing occurs at each phase of the NPD process, managers can be prepared and correctly implement tools to support NPD teams from both buyer and supplier companies.

RESUMO Racional: O desfecho satisfatório na abordagem cirúrgica da obesidade deve contemplar, além da perda de peso, alteração significativa nas comorbidades preexistentes e na qualidade de vida dos pacientes. Objetivo: Avaliar a qualidade de vida no pós-operatório tardio de pacientes submetidos à cirurgia de gastrectomia vertical por videolaparoscopia. Métodos: Foi aplicado o questionário "Bariatric Analysis and Reporting Outcome System" (BAROS) em pacientes submetidos à gastrectomia vertical por videolaparoscopia. Resultados: Foram avaliados 47 pacientes, entre 21 e 60 anos de idade. O IMC médio antes da operação era 43,06±5,87 kg/m². A média percentual de redução do excesso de peso após foi de 85,46±23,6%.

Conclusão: A perda de peso foi fundamental para a melhoria na qualidade de vida e proporcionou resolução ou a melhora clínica em todas as comorbidades investigadas.

ABSTRACT Background: Mesenteric ischemia is a challenging diagnosis. Delay in diagnosis can lead to extent bowel necrosis and poor outcomes. Ischemia and reperfusion syndrome plays an important role in this scenario. Aim: To access effects of different post-conditioning cycles on mesenteric ischemia-reperfusion syndrome. Method: Twenty-five rats were assigned into five groups: Sham, used to establish normal parameters; control group, submitted to mesenteric ischemia for 30 min; in groups GP3, GP1 and GP30, ischemia was followed by post-conditioning protocol, which consisted of 1 cycle of 3 min (GP3), 3 cycles of 1 min (GP1) or 6 cycles of 30 s (GP30), respectively. Ileum samples were harvested after one hour of reperfusion. Intestinal mucosal injury was evaluated through histopathological analysis. Results: The average of mesenteric injury degree was 0 in the sham group, 3.6 in the control group, 3.4 in GP3, 3.2 in GP1, and 3.0 in GP30; villous length average was 161.59 in sham group, 136.27 in control group, 135.89 in GP3, 129.46 in GP1, and 135.18 in GP30. Was found significant difference between sham and other groups (p<0.05); however, there was no difference among post-conditioning groups. Conclusion: Post-conditioning adopted protocols were not able to protect intestinal mucosa integrity after mesenteric ischemia and short term reperfusion.
