High-resolution 3-dimensional tomography may be a useful tool for understanding the anatomy of hiatal hernias and surgical planning of patients eligible for laparoscopic or robotic antireflux surgery.

BACKGROUND: 3D computed tomography (CT) has been seldom used for the evaluation of hiatal hernias (HH) in surgical patients. This study aims to describe the 3D CT findings in candidates for laparoscopic or robotic antireflux surgery or HH repair and compare them with other tests. METHODS: Thirty patients with HH and/or gastroesophageal reflux disease (GERD) who were candidates for surgical treatment and underwent high-resolution CT were recruited. The variables studied were distance from the esophagogastric junction (EGJ) to the hiatus; total gastric volume and herniated gastric volume, percentage of herniated volume in relation to the total gastric volume; diameters and area of the esophageal hiatus. RESULTS: HH was diagnosed with CT in 21 (70%) patients. There was no correlation between the distance EGJ-hiatus and the herniated gastric volume. There was a statistically significant correlation between the distance from the EGJ to the hiatus and the area of the esophageal hiatus of the diaphragm. There was correlation between tomographic and endoscopic findings for the presence and size of HH. HH was diagnosed with manometry in 9 (50%) patients. There was no correlation between tomographic and manometric findings for the diagnosis of HH and between hiatal area and lower esophageal sphincter basal pressure. There was no correlation between any parameter and DeMeester score. CONCLUSIONS: The anatomy of HH and the hiatus can be well defined by 3D CT. The EGJ-hiatus distance may be equally measured by 3D CT or upper digestive endoscopy. DeMeester score did not correlate with any anatomical parameter.

e-Seating - Aplicativo para apoiar o processo de avaliação e prescrição de cadeira de rodas e dispositivos de adequação postural: avaliação da experiência do usuário / e-Seating - Application to support evaluation and prescription process of wheelchairs and postural support devices: user experience evaluation

Objetivo: Avaliar a usabilidade do aplicativo e-Seating no estado de MVP, levando em consideração a experiência dos prescritores na prática clínica. Métodos: Foi utilizada a Design-Based Research (DBR) e a metodologia ágil Scrum com abordagem de desenvolvimento iterativo para aperfeiçoamento do e-Seating, considerando as avaliações dos usuários por um questionário de Experiência do Usuário - UEQ (sigla para User Experience Questionnaire) baseado em Schrepp, Hinderks e Thomaschewski. Foram realizados 3 testes com 17 profissionais prescritores de cadeira de rodas, sendo divididos para teste 1 com 6 profissionais, teste 2 com 5 e teste 3 com 6 profissionais. Os dados foram analisados por teste estatístico (teste t) e ferramenta de análise do UEQ. Resultados: Com a avaliação de experiência do usuário e aperfeiçoamento constante do e-Seating com base nas avaliações, conclui-se que o e-Seating teve maior aceitabilidade pelos prescritores que trabalham em locais privados e com profissionais autônomos do que com profissionais que atuam no setor público. Conclusão: O uso do App pode apoiar os profissionais de reabilitação no processo de prescrição de cadeira de rodas, ajudando a sistematizar e integrar as informações em toda jornada do paciente.

Objective: To evaluate the usability of the e-Seating application in the MVP state, taking into account the experience of prescribers in clinical practice. Methods: Design-Based Research (DBR) and agile Scrum methodology with an iterative development approach were used to improve e-Seating, considering user evaluations through a User Experience Questionnaire - UEQ based on Schrepp, Hinderks and Thomaschewski. Three tests were performed with 17 wheelchair prescribers, being divided into test 1 with 6 professionals, test 2 with 5 and test 3 with 6 professionals. Data were analyzed by statistical test (t test) and UEQ analysis tool. Results: With the evaluation of user experience and constant improvement of e-Seating based on the evaluations, it was concluded that e-Seating was more acceptable by prescribers who work in private places and with self-employed professionals than with professionals who work in the Public sector. Conclusion: The use of the App can support rehabilitation professionals in the wheelchair prescription process, helping to systematize and integrate information throughout the patient's journey.

An Automated Electronic System in a Motorized Wheelchair for Telemonitoring: Mixed Methods Study Based on Internet of Things.

BACKGROUND: Wheelchair positioning systems can prevent postural deficits and pressure injuries. However, a more effective professional follow-up is needed to assess and monitor positioning according to the specificities and clinical conditions of each user. OBJECTIVE: This study aims to present the concept of an electronic system embedded in a motorized wheelchair, based on the Internet of Things (IoT), for automated positioning as part of a study on wheelchairs and telemonitoring. METHODS: We conducted a mixed methods study with a user-centered design approach, interviews with 16 wheelchair users and 66 professionals for the development of system functions, and a formative assessment of 5 participants with descriptive analysis to design system concepts. RESULTS: We presented a new wheelchair system with hardware and software components developed based on coparticipation with singular components in an IoT architecture. In an IoT solution, the incorporation of sensors from the inertial measurement unit was crucial. These sensors were vital for offering alternative methods to monitor and control the tilt and recline functions of a wheelchair. This monitoring and control could be achieved autonomously through a smartphone app. In addition, this capability addressed the requirements of real users. CONCLUSIONS: The technologies presented in this system can benefit telemonitoring and favor real feedback, allowing quality provision of health services to wheelchair users. User-centered development favored development with specific functions to meet the real demands of users. We emphasize the importance of future studies on the correlation between diagnoses and the use of the system in a real environment to help professionals in treatment.

Cultural adaptation and validation of the Brazilian Portuguese version of the PROactive Physical Activity in COPD-clinical visit instrument for individuals with COPD.

OBJECTIVE: To adapt the PROactive Physical Activity in COPD-clinical visit (C-PPAC) instrument to the cultural setting in Brazil and to determine the criterion validity, test-retest reliability agreement, and internal consistency of this version. METHODS: A protocol for cultural adaptation and validation was provided by the authors of the original instrument and, together with another guideline, was applied in a Portuguese-language version developed by a partner research group from Portugal. The adapted Brazilian Portuguese version was then cross-sectionally administered twice within a seven-day interval to 30 individuals with COPD (57% were men; mean age was 69 ± 6 years; and mean FEV1 was 53 ± 18% of predicted) to evaluate internal consistency and test-retest reliability. Participants also completed the International Physical Activity Questionnaire (IPAQ), the modified Medical Research Council scale, the COPD Assessment Test, and Saint George's Respiratory Questionnaire to evaluate criterion validity. RESULTS: The C-PPAC instrument showed good internal consistency and excellent test-retest reliability: "amount" domain = 0.87 (95% CI, 0.73-0.94) and "difficulty" domain = 0.90 (95% CI, 0.76-0.96). Bland & Altman plots, together with high Lin's concordance correlation coefficients, reinforced that agreement. Criterion validity showed moderate-to-strong correlations of the C-PPAC with all of the other instruments evaluated, especially with the IPAQ (rho = -0.63). CONCLUSIONS: The Brazilian Portuguese version of the C-PPAC is a reliable and valid instrument for evaluating the experience of Brazilian individuals with COPD with their physical activity in daily life.

Spatial distribution and temporal trends of butyltin compounds (TBT, DBT & MBT) in short sediment cores of the SW Portuguese Shelf (western Iberian Margin, NE Atlantic).

Spatial patterns and temporal trends of the butyltin compounds tributyltin (TBT), dibutyltin (DBT), and monobutyltin (MBT) were investigated in a set of sediment samples collected along the SW Portuguese continental shelf. This region did not reach the Good Environmental Status (GES) in accordance with the Marine Strategy Framework Directive (MSFD) during a first evaluation carried out in 2012. Overall, MBT and DBT were the predominant organotin species detected, but high concentrations of TBT were found in and around disposal sites for dredge sludge derived from the dredging in navigation channels, harbours, and shipyard facilities of the Tagus and Sado estuaries. Although Portuguese regulations for monitoring sediment quality in relation to dredging activities consider only PAH, PCB and HCB, they also dictate that other organic contaminants such as butyltin compounds (BTs) should be monitored if suspicion of high values exists, but no action limits are defined for these (MAOTDR, 2007). Without action limits, the monitoring recommendation given in the regulations is not put into practice. Considering their toxicity, BT derivates should be integrated in the legislation, because they represent an environmental threat in the relocation of dredged material, especially when derived from harbour and shipyards areas. Based on this study, we recommend giving more attention to the amounts and impacts of BTs in sediments at dredged material disposal sites (DMDS) and their surroundings. Or even better, in order to be more efficient, monitoring should be done at the source of the dredged materials and not at the sink. In case it is not done, the monitoring of concentrations of TBT (and other BTs) in sediments and organisms, including imposex studies, at all Portuguese sites for disposal of dredged material receiving slightly to strongly contaminated dredged material must be developed.

Acute phase proteins levels in horses, after a single carbohydrate overload, associated with cecal alkalinization.

Introduction: Horses submitted to carbohydrate overload can develop laminitis due to changes in cecal pH and microbiota, followed by an increase in transmural absorption of luminal content, including bacterial toxins. In response to acute injury there is hepatic overproduction of several proteins known as acute phase proteins (APP). Few studies have evaluated protein fractionation to characterize the inflammatory response in acute laminitis. The aim of this study was to test the viability of an experimental model to induce acute laminitis, using a single carbohydrate overload, and the influence of a buffering solution on the development of the disease; also, study the kinetics of APP during acute laminitis, as well as the correlation between these proteins and clinical signs associated to this syndrome. Methods: Ten healthy horses were divided in a factorial and randomized way into four groups (n = 5): control group (CG), starch group (SG), buffer group (BG), and starch C buffer group (SBG). They were evaluated at seven times (T0h, T4h, T8h, T12h, T24h, T48h, and T72h), which included clinical evaluation and blood sample collection. Total serum protein and albumin concentrations were determined by colorimetry and the other APP by polyacrylamide gel electrophoresis containing sodium dodecyl sulfate and commercial ELISA kits. Data were analyzed by two-way ANOVA, followed by Tukey's test (p < 0.05). The correlation between clinical signs and APP were verified using the Pearson's correlation coefficient. Results and discussion: 40% of the animals from SG and 60% from SBG developed clinical laminitis. A single administration of buffer solution was not able to prevent clinical signs of laminitis. There was no difference between groups on total serum protein, albumin, serum amyloid A and C-reactive protein concentrations (p > 0.05). Transferrin, considered a negative APP, showed a positive response pattern in SG and SBG. Ceruloplasmin had a positive correlation with Obel grade, heart rate on animals from SGB and number of steps on horses submitted to starch overload (SG and SBG). Ceruloplasmin, α-1-antitrypsin and haptoglobin concentrations increased in SBG, suggesting an inflammatory response in animals of this group. Changes in clinical parameters were also more evident in the SBG, corroborating the protein fractionation findings.

RESUMO Objetivo: Adaptar o instrumento PROactive Physical Activity in COPD - clinical visit (C-PPAC) ao contexto cultural brasileiro e determinar a validade de critério, concordância da confiabilidade teste-reteste e consistência interna dessa versão. Métodos: Um protocolo de adaptação cultural e validação foi fornecido pelos autores do instrumento original e, juntamente com outra diretriz, foi aplicado em uma versão em português desenvolvida por um grupo de pesquisa parceiro de Portugal. A versão brasileira adaptada foi então aplicada transversalmente duas vezes, com intervalo de sete dias, em 30 indivíduos com DPOC (57% de homens; média de idade de 69 ± 6 anos; e média do VEF1 de 53 ± 18% do previsto) para avaliação da consistência interna e da confiabilidade teste-reteste. Os participantes também responderam ao International Physical Activity Questionnaire (IPAQ), à escala modificada do Medical Research Council, ao COPD Assessment Test e ao Saint George's Respiratory Questionnaire para avaliação da validade de critério. Resultados: O instrumento C-PPAC apresentou boa consistência interna e excelente confiabilidade teste-reteste: domínio "quantidade" = 0,87 (IC95%: 0,73-0,94) e domínio "dificuldade" = 0,90 (IC95%: 0,76-0,96). As disposições gráficas de Bland-Altman, juntamente com os altos coeficientes de correlação de concordância de Lin, reforçaram essa concordância. A validade de critério mostrou correlações moderadas a fortes do instrumento C-PPAC com todos os outros instrumentos avaliados, principalmente com o IPAQ (rho = −0,63). Conclusões: A versão brasileira do instrumento C-PPAC é uma ferramenta confiável e válida para avaliar a experiência de indivíduos brasileiros com DPOC em relação à sua atividade física na vida diária.

Do simple and quick functional tests reflect a more comprehensive test or physical activity in daily life in healthy young subjects? / Testes funcionais simples e rápidos refletem um teste mais abrangente ou atividade física na vida diária em jovens saudáveis? / ¿Los tests funcionales simples y rápidos reflejan un test más completo o actividad física en la vida diaria en jóvenes sanos?

ABSTRACT Considering the wide use of functional tests and that faster and simpler evaluations are preferable, this study aimed to verify the association between five protocols of simple functional tests (timed up and go [TUG], four-meter gait speed [4MGS] and sit-to-stand [STS] in five-repetitions [STS5rep], 30-seconds [STS30sec] and one-minute [STS1min] protocols) and the six-minute walk test (6MWT), as well as physical activity in daily life (PADL) in healthy young subjects. In this cross-sectional study, PADL was quantified by a pedometer validated for step counting and we considered the mean of seven consecutive days during the time awake. We assessed functional capacity by the TUG, 4MGS, STS5rep, STS30sec, and STS1min tests and the 6MWT. A total of 79 subjects without lung functional impairments were included (49% male, aged 28 [23-36] years). Performance of simple functional tests correlated with the 6MWT (0.23<r <0.56; P<0.05 for all) and the TUG test showed the best association (R2= 0.34). However, simple functional tests did not correlate with PADL (0.03< r <0.13; P>0.05 for all). The less time-consuming functional tests were weakly-moderately related to the 6MWT in healthy young subjects. The TUG showed the best association and explained up to 34% of the 6MWT. However, the 6MWT cannot be replaced by none of these simple functional tests. Finally, functional capacity showed no association with physical activity in daily life assessed by the pedometers in this population.

RESUMO Considerando o amplo uso de testes funcionais e que avaliações mais rápidas e simples são preferíveis, o objetivo deste estudo foi verificar a associação entre cinco protocolos de testes funcionais, a saber, timed up and go [TUG], 4-meter gait speed [4MGS] and sit to stand [STS] in 5-repetitions [STS5rep], 30-seconds [STS30sec] and 1-minute [STS1min] protocols e o teste de caminhada de 6 minutos (TC6min), bem como com a atividade física na vida diária (AFVD) em jovens saudáveis. Neste estudo transversal, a AFVD foi quantificada por um pedômetro validado para contagem de passos, e a média de sete dias consecutivos durante o tempo acordado foi considerada. A capacidade funcional foi avaliada pelo TUG, 4MGS, STS5rep, STS30sec, STS1min e TC6min. 79 pessoas sem comprometimento pulmonar foram incluídas (49% homens, idade média de 28 anos). O desempenho nos testes funcionais correlacionou-se com o TC6min (0,23< r <0,56; p<0,05 para todos) e o TUG apresentou a melhor associação (R²=0,34). Entretanto, os testes funcionais simples não se correlacionaram com a AFVD (0,03<r<0,13; p>0,05 para todos). Os testes funcionais de curta duração foram fracos, moderadamente relacionados ao TC6min em jovens saudáveis. O TUG apresentou a melhor associação e explicou até 34% do TC6min; no entanto, este não pode ser substituído por nenhum dos testes funcionais simples. Por fim, a capacidade funcional não se relacionou com a atividade física na vida diária avaliada pelos pedômetros nessa população.

RESUMEN Teniendo en cuenta el amplio uso de los tests funcionales y que son preferibles evaluaciones más rápidas y sencillas, el objetivo de este estudio fue verificar la asociación entre cinco protocolos de tests funcionales, a saber, timed up and go [TUG], 4-meter gait speed [4MGS] and sit to stand [STS] in 5-repetitions [STS5rep], 30-seconds [STS30sec] and 1-minute [STS1min] protocols y la prueba de caminata de 6 minutos (6MWT), con la actividad física de la vida diaria (AFVD) en jóvenes sanos. En este estudio transversal, la AFVD se cuantificó mediante un podómetro validado para el conteo de pasos, y se consideró el promedio de siete días consecutivos durante el tiempo acordado. La capacidad funcional se evaluó mediante TUG, 4MGS, STS5rep, STS30sec, STS1min y 6MWT. Se incluyeron a 79 personas sin afectación pulmonar (49% hombres, edad media 28 años). El desempeño en los tests funcionales se correlacionó con la 6MWT (0,23< r <0,56; p<0,05 para todos), y el TUG tuvo la mejor asociación (R²=0,34). Sin embargo, los tests funcionales simples no se correlacionaron con la AFVD (0,03<r<0,13; p>0,05 para todos). Los tests funcionales a corto plazo fueron insuficientes, moderadamente relacionados con la 6MWT en jóvenes sanos. El TUG mostró la mejor asociación y explicó hasta el 34% de la 6MWT, pero este no puede reemplazarse por ninguno de los tests funcionales simples. Por último, la capacidad funcional no se relacionó con la actividad física en la vida diaria evaluada por podómetros en esta población.

COMPLICATIONS AND LATE FOLLOW-UP OF SCOPINARO'S SURGERY WITH GASTRIC PRESERVATION: 1570 PATIENTS OPERATED IN 20 YEARS.

AIMS: Scopinaro-type biliopancreatic diversion (BPD-S) and its variations are the surgeries that offer the best immediate results in weight loss and regain in the late follow-up. It has a high rate of immediate complications and demands control with frequent laboratory tests. The aim of this study was to analyze the late postoperative complications of 1570 patients operated by biliopancreatic diversion with gastric preservation laparoscopic video with up to 20 years of postoperative follow-up. METHODS: In a follow-up period of up to 20 years, the clinical and surgical complications of 1570 patients with grade II or III obesity were evaluated who were operated on from 2001 to 2014 with the same team of surgeons. Clavien Dindo 11 classification was used for analysis and comparison. Laboratory tests and body mass index (BMI) were used in the analysis of late metabolic outcomes. RESULTS: On the one hand, complications in 204 patients were recorded (13%), and 143 patients (9.1%) were reoperated. On the other hand, 61 patients (29.9%), who had postoperative complications were clinically treated with good evolution in 9.2 years (95%CI 8.2-10.3), with a median of 9.5 years (95%CI 6.1-12.9). Gastroileal anastomosis ulcers occurred in 44 patients (2.8%). Patients with malnutrition, severe anemia, or chronic diarrhea were operated on with common loop elongation (n=64 - 4%), conversion to gastric diversion (n=29 - 5%), or reversal of surgery (n=10 - 0.6%). One death was registered throughout casuistry (0.06%). CONCLUSIONS: Metabolic result of DBP-S was considered excellent in most patients, even referring to changes in the frequency of bowel movements, loose stools, and unpleasant odor. Complications are usually serious and most of the patients require surgical treatment. Therefore, the biliopancreatic diversion of Scopinaro should be reserved for exceptional cases, as there are safer surgical alternatives with less serious side effects.

Multicomponent Quantum Mechanics/Molecular Mechanics Study of Hydrated Positronium.

We propose a model for solvated positronium (Ps) atoms in water, based on the sequential quantum mechanics/molecular mechanics (s-QM/MM) protocol. We developed a Lennard-Jones force field to account for Ps-water interactions in the MM step. The repulsive term was obtained from a previously reported model for the solvated electron, while the dispersion constant was derived from the Slater-Kirkwood formula. The force field was employed in classical Monte Carlo (MC) simulations to generate Ps-solvent configurations in the NpT ensemble, while the quantum properties were computed with the any-particle molecular orbital method in the subsequent QM step. Our approach is general, as it can be applied to other liquids and materials. One basically needs to describe the solvated electron in the environment of interest to obtain the Ps solvation model. The thermodynamical properties computed from the MC simulations point out similarities between the solvation of Ps and noble gas atoms, hydrophobic solutes that form clathrate structures. We performed convergence tests for the QM step, with particular attention to the choice of basis set and expansion centers for the positronic and electronic subsystems. Our largest model was composed of the Ps atom and 22 water molecules in the QM region, corresponding to the first solvation shell, surrounded by 128 molecules described as point charges. The mean electronic and positronic vertical detachment energies were (4.73 ± 0.04) eV and (5.33 ± 0.04) eV, respectively. The latter estimates were computed with Koopmans' theorem corrected by second-order self-energies, for a set of statistically uncorrelated MC configurations. While the Hartree-Fock wave functions do not properly account for the annihilation rates, they were useful for numerical tests, pointing out that annihilation is more sensitive to the choice of basis sets and expansion centers than the detachment energies. We further explored a model with reduced solute cavity size by changing the Ps-solvent force field. Although the pick-off annihilation lifetimes were affected by the cavity size, essentially the same conclusions were drawn from both models.

Laparoscopic appendicectomy without the use of disposable materials - a low-cost alternative - 1,552 cases operated in 20 years.

INTRODUCTION: Laparoscopic appendectomy does not have a single protocol on its technical systematization, access routes, and use of energy and staplers. The cost of disposable materials can prevent its widespread use. Alternatives to decrease cost can help disseminate the laparoscopic access to appendectomy. OBJECTIVE: to introduce a low-cost laparoscopic appendectomy method with good aesthetic results through the location of incisions; to show its viability through its application in 1,552 cases of laparoscopic appendectomy operated between 2000 and 2019 with three portals and very low-cost regarding materials used. METHODS: we applied three punctures - an umbilical one for the camera (5 or 10mm in diameter), a 10mm puncture in the right iliac fossa, and one 5mm puncture in the left iliac fossa. The materials used were permanent use trocars, grasping forceps, hook, scissors, and needle holder, without the need for any disposable device. RESULTS: 1.552 patients were operated between 2000 and 2019, 56.2% being female, mean age 32.66 years (9-93), average hospital stay of 1.74 days (1-10), and median of 1.2 days. CONCLUSION: the technique we describe uses three metallic trocars and four permanent instruments, in addition to a single cotton suture. It is, therefore, a very low-cost laparoscopic procedure. Its application has shown good results and low morbidity, which may become the preferred indication for laparoscopic surgery in the treatment of acute appendicitis.

RESUMO - RACIONAL - A derivação biliopancreática tipo Scopinaro (DBP-S) e suas variações são as cirurgias que oferecem os melhores resultados imediatos na perda de peso e de reganho de peso no acompanhamento tardio. Apresenta índice elevado de complicações imediatas e demanda controle laboratorial frequente. OBJETIVOS - Analisar as complicações pós-operatórias tardias de 1.570 pacientes operados por derivação biliopancreática com preservação gástrica videolaparoscópica com até 20 anos de acompanhamento pós-operatório. MÉTODOS - Foram avaliadas as complicações clínicas e cirúrgicas, no acompanhamento tardio de até 20 anos, de 1.570 pacientes com obesidade grau II ou III, operados no período de 2001 a 2014, por uma mesma equipe de cirurgiões. A classificação de Clavien Dindo 11 foi empregada para análise e comparação. Exames laboratoriais e índice de massa corpórea (IMC) foram utilizados na análise dos resultados metabólicos tardios. RESULTADOS - Foram registradas complicações em 204 pacientes (13%), e 143 (9,1%) foram reoperados. Por outro lado, 61 pacientes (29,9%), no período de 9,2 anos (IC 95% 8,2-10,3), com mediana de 9,5 anos (IC 95% 6,1-12,9), que tiveram complicações pós-operatórias foram tratados clinicamente, com boa evolução. A úlcera de anastomose gastroileal ocorreu em 44 pacientes (2,8%). Os pacientes com desnutrição, anemia grave ou diarreia crônica foram operados com alongamento da alça comum (n=64 - 4%), conversão para bypass gástrico (n=29 - 5%) ou reversão da cirurgia (n=10 - 0,6%). Foi registrado um óbito ao longo de toda a casuística (0,06%). CONCLUSÕES - O resultado metabólico da DBP-S foi considerado excelente na maioria dos pacientes, mesmo referindo-se a alteração da frequência de evacuações, fezes amolecidas e com odor desagradável. As complicações são geralmente graves e a maioria demanda tratamento cirúrgico. Portanto, a derivação biliopancreática de Scopinaro deve ser reservada a casos excepcionais, pois existem alternativas cirúrgicas mais seguras e com efeitos colaterais menos graves.

RESUMO Introdução: a apendicectomia videolaparoscópica não tem protocolo único sobre sistematização técnica, vias de acesso, uso de energia e grampeadores. O custo de materiais descartáveis pode inviabilizar o emprego mais generalizado. Alternativas para diminuir o custo podem ajudar a disseminar o acesso laparoscópico para a realização de apendicectomia. Objetivo: introduzir um método para realizar a apendicectomia videolaparoscópica de baixo custo e visando bom resultado estético por meio da localização das incisões; mostrar a viabilidade por meio de aplicação em 1.552 casos de apendicectomia videolaparoscópica operados entre 2000 e 2019 com três portais, de muito baixo custo em insumos utilizados. Métodos: três punções - uma punção umbilical para introdução da câmera (de 5 ou 10mm de diâmetro), uma punção de 10mm em fossa ilíaca direita e uma punção em fossa ilíaca esquerda de 5mm. Os materiais utilizados - trocartes, pinças de apreensão, gancho, tesoura e porta-agulhas são de uso permanente, sem necessidade de qualquer material descartável. Resultados: foram operados 1.552 pacientes entre 2000 e 2019, sendo 56,25% do sexo feminino, média de idade de 32,66 anos (9 a 93 anos), tempo médio de internação de 1,74 dias (1 a 10 dias) e mediana de 1,2 dias. Conclusão: a técnica que descrevemos utiliza três trocartes metálicos e quatro instrumentos permanentes, além de um único fio de algodão. Trata-se, portanto, de procedimento laparoscópico de muito baixo custo. A aplicação demonstrou bons resultados e baixa morbidade, podendo tornar-se rotina a indicação preferencial da vídeocirurgia no tratamento da apendicite aguda.

Evaluation of ApaI and FokI polymorphism of VDR gene and functional characterization in patients with fibromyalgia / Avaliação do polimorfismo ApaI e FokI do gene VDR e caracterização funcional em pacientes com fibromialgia

Abstract Introduction: Fibromyalgia (FM) is a syndrome of unknown origin characterized by several symptoms, and although its pathogenesis has not been completely elucidated, it seems to be related to inflammatory path-ways and neurochemical changes in the brain. Objective: To evaluate the association between BsmI, ApaI and FokI polymorphisms of the vitamin D receptor (VDR) gene, their polymorphisms, and clinical variables in women with and without FM. Methods: This is a case-control study composed of a group of 53 women with FM and another with 40 women without the disease. The McGill Pain Questionnaire, Fibromyalgia Impact Questionnaire, Pain Visual Analogue Scale and the sit-up test were applied. Real-time PCR was performed to analyze the ApaI and FokI polymorphism. Results: There was a statistical association between race, comorbidity and FM, where 78.4% of the individuals were white and had FM (p < 0.002) and 96.1% had some comorbidity (p < 0.001). Seventy-six point five percent (76.5%) of patients with FM underperformed in the sit-up test (p < 0.001). There was also an association between the genotypic and allele frequencies of the VDR and FM gene Apal and FokI polymorphisms (p < 0.001). In the VDR gene ApaI polymorphism, the CC genotype exhibited a higher frequency in women with FM, the C allele for the Apal polymorphism was 3.33 times more likely, and the FokI polymorphism was 10.9 times more likely to develop FM (p < 0,0001). Conclusion: Women with C allele for ApaI polymorphism are 3.33 times more likely to have FM (95%CI = 1.58-7.02; p = 0.0024), and in FokI polymorphism, the prevalence of T allele is 10.9 times greater (95% CI = 4.76-25.38; p < 0.0001). No significant associations were found in relation to BsmI polymorphism and frequency alleles (p = 0.062 and p = 0.078, respectively).

Resumo Introdução: A fibromialgia (FM) é uma síndrome de origem desconhecida caracterizada por diversos sintomas, e embora sua patogênese não tenha sido completamente elucidada, parece estar relacionada às vias inflamatórias e alterações neuroquímicas no cérebro. Objetivo: Avaliar a associação entre os polimorfismos BsmI, ApaI e FokI do gene do receptor da vitamina D (VDR), seus polimorfismos e variáveis clínicas em mulheres com e sem FM. Métodos: Trata-se de um estudo caso-controle composto por um grupo de 53 mulheres com FM e outro com 40 mulheres sem a doença. Foram aplicados o Questionário de Dor de McGill, Questionário de Impacto da Fibromialgia, Escala Visual Analógica da Dor e o teste de sentar. A PCR em tempo real foi realizada para analisar o polimorfismo ApaI e FokI. Resultados: Houve associação estatística entre raça, comorbidade e FM, onde 78,4% dos indivíduos eram brancos e apresentavam FM (p < 0,002) e 96,1% tinham alguma comorbidade (p < 0,001). Setenta e seis vírgula cinco por cento (76,5%) dos pacientes com FM tiveram desempenho inferior no teste de abdominais (p < 0,001). Também houve associação entre as frequências genotípicas e alélicas dos polimorfismos Apal e FokI do gene VDR e FM (p < 0,001). No polimorfismo ApaI do gene VDR, o genótipo CC apresentou maior frequência em mulheres com FM, o alelo C para o polimorfismo Apal foi 3,33 vezes mais provável, e o polimorfismo FokI teve 10,9 vezes mais chance de desenvolver FM (p < 0,0001). Conclusão: Mulheres com alelo C para polimorfismo ApaI têm 3,33 vezes mais chance de ter FM (IC 95% = 1,58-7,02; p = 0,0024), e no polimorfismo FokI, a prevalência do alelo T é 10,9 vezes maior (IC 95% = 4,76-25,38; p < 0,0001). Não foram encontradas associações significativas em relação ao polimorfismo BsmI e alelos de frequência (p = 0,062 e p = 0,078, respectivamente).

ntrodução: Avaliar os parâmetros de qualidade da água é fundamental para a vigilância em saúde pública e o direcionamento de ações de prevenção de doenças no âmbito populacional. Objetivo: Realizar a análise dos dados de vigilância de parâmetros químicos, físicos e microbiológicos para avaliação da qualidade da água de consumo humano no estado do Amazonas, com base no Sistema de Informação de Vigilância da Qualidade da Água para Consumo Humano (Sisagua). Método: Estudo exploratório-descritivo baseado em pesquisa quantitativa para a análise da vigilância da qualidade da água de consumo humano e de parâmetros químicos, físicos e microbiológicos nas amostras de água no estado do Amazonas, no período de 2016 a 2020. Testes estatísticos não paramétricos foram realizados para comparar diferenças na proporção de cada categoria e adequação de acordo com a microrregião geográfica. Resultados: As microrregiões do interior apresentam menor proporção de municípios com registro de informações sobre a qualidade da água. As amostras da microrregião da capital apresentaram menor teor de cloro residual livre, maior concentração de fluoreto, e valores superiores para coloração aparente e turbidez. As análises de tendências evidenciaram melhorias nos parâmetros para cor aparente em amostras obtidas na microrregião de capital e, para cloro residual livre, coliformes totais e Escherichia coli em amostras de água coletadas no interior. Conclusões: Houve diferenças no percentual de inadequações dos parâmetros das amostras avaliadas de acordo com a localidade. Ressalta-se a necessidade de melhorias na gestão da vigilância da qualidade da água, no que se refere ao olhar atento para as ações de análise e fiscalização no estado do Amazonas.

Introduction: The evaluation of water quality parameters is fundamental for public health and disease prevention in the population. Objective: To perform an analysis of surveillance data of chemical, physical, and microbiological parameters to evaluate the quality of water for human consumption in the State of Amazonas, based on the Information System of Water Quality Surveillance for Human Consumption (Sisagua). Method: An exploratory-descriptive study based on quantitative research was carried out to analyze the quality of human consumption water and chemical, physical, and microbiological parameters, measured in water samples in the State of Amazonas, from 2016 to 2020. Nonparametric statistical tests were performed to compare differences in the proportion of each category and adequacy according to the geographic microregion. Results: Inland micro-regions have a lower proportion of municipalities with data recording of water quality parameters. The water samples from the microregion of the capital presented lower free residual chlorine content, higher fluoride concentration, and higher values for apparent color and turbidity. Trend analyses showed improvements in parameters for apparent color in samples obtained in the capital microregion and, for free residual chlorine, total coliforms and Escherichia coli in water samples collected in the interior of Amazonas. Conclusions: There were differences in the profile of chemical, physical, and microbiological parameters of the samples evaluated according to the locality. The need for improvements in the management of water quality surveillance is emphasized, especially related to looking carefully at the actions of analysis and supervision in the State of Amazonas.

Comparative Analysis Using Pulsed-Field Gel Electrophoresis Highlights a Potential Transmission of Salmonella Between Asymptomatic Buffaloes and Pigs in a Single Farm.

Buffaloes and pigs play an important epidemiological roll in the Salmonella infection cycle, and asymptomatic animals can act as key component in the dissemination of the disease by horizontal, vertical, and cross-species transmission. Our study aimed and was able to confirm evidences of a cross-species transmission of Salmonella Agona between asymptomatic buffaloes and pigs. Also, we described Salmonella infection within the pig production phases, involving serotypes Agona, Senftenberg and Schwarzengrund. Rectal samples were collected from Jafarabadi buffaloes (n = 25) and Piau pigs (n = 32), located on a single farm. Salmonella Agona was isolated from lactating buffaloes, gilts, pregnant sows, and weaned pigs, Salmonella Schwarzengrund from lactating sows and Salmonella Senftenberg from gilts, pregnant sows, lactating sows, and weaned pigs. Pulsed-field Gel Electrophoresis protocol (PFGE) was performed and revealed four different profiles. Profile 1 (Salmonella Agona), isolated from a pregnant sow, a gilt and two lactating buffaloes, revealed a indistinguishable PFGE pattern, confirming evidences of potential cross-species transmission. Profile 2 (Salmonella Agona), 3 (Salmonella Senftenberg), and 4 (Salmonella Schwarzengrund), isolated from pigs, revealed important indistinguishable PFGE patterns, evidencing Salmonella infection within the pig production phases. Considering the epidemiological relevance of buffaloes and pigs in the cycle of Salmonella infection, confirmation of a potential cross-species transmission of Salmonella Agona and potential Salmonella infection within the pig production phases highlights the importance of the correct establishment of preventive health strategies in farms, in special the importance of avoiding contact between buffaloes and pigs, since cross-species transmission can occur, increasing the risk of spreading the disease.

Avaliação dos indicadores de aquisição, disponibilidade e adequação nutricional da cesta básica de alimentos brasileira / Assessment of the indicators of purchasing, availability, and nutritional adequacy of the Brazilian basic food basket

Resumo O objetivo deste estudo foi avaliar a evolução dos custos para aquisição da cesta básica associados ao poder aquisitivo do salário mínimo, além de mensurar a disponibilidade per capita nos domicílios brasileiros dos alimentos que compõem a cesta básica. Também foram avaliadas a adequação da composição nutricional e a qualidade da dieta baseada no consumo diário de itens da cesta básica. Os resultados obtidos apontam a existência de períodos de elevação de preços para aquisição dos itens da cesta básica, assim como a incapacidade do salário mínimo para o custeio para tais provisões alimentares. Foi verificado que as dietas baseadas no consumo dos itens da cesta básica apresentam quantidade de energia e sódio superiores às recomendações para indivíduos adultos, além de apresentar quantidades insuficientes de cálcio, potássio e vitamina A. A avaliação da qualidade das dietas apontou baixa quantidade de frutas, vegetais, cereais na dieta composta pelos itens das cestas básicas, sendo constatado excesso energético proveniente de gorduras e açúcar de adição. Diante de tais evidências, recomenda-se revisão da composição das cestas básicas para atendimento de requisitos nutricionais básicos em alimentação para população brasileira.

Abstract The scope of this study was to assess the evolution of costs for purchasing the basic food basket associated with the purchasing power of the minimum wage, besides measuring the availability per capita in Brazilian households of the items comprised in the food basket. Additionally, adequacy of the nutritional composition and diet quality based on daily consumption of food basket items was evaluated. The results obtained indicate the existence of periods of price increase for the acquisition of the food basket items, as well as the inability of the minimum wage to meet the cost of such food supplies. It was verified that the diets based on the consumption of food basket items have a higher calorie and sodium content than the recommendations for adults, as well as insufficient amounts of calcium, potassium, and vitamin A. The evaluation of the quality of the diets indicated low amounts of fruit, vegetables, cereals in the diet consisting of the items of the food baskets, with excess calories from fats and added sugar being verified. In view of such evidence, a review of the composition of the food baskets is recommended in order to meet basic nutritional requirements in food for the Brazilian population.
