ABSTRACT Purpose To analyze the learning curve regarding complication rates of transrectal prostate biopsy (TRPB) versus transperineal prostate biopsy (TPPB), using real time software-based magnetic resonance imaging ultrasound (MRI-US) fusion techniques, along with first year experience of transperineal approach. Materials and Methods retrospective unicentric cohort study at a quaternary care hospital. Medical records of all consecutive patients that underwent TPPB between March 2021 and February 2022, after the introduction of MRI-US fusion device, and those who underwent TRPB throughout the entire years of 2019 and 2020 were analyzed. All complications that occurred as consequences of the procedure were considered. Descriptive statistics, Chi-squared and Fisher tests were used to describe complications and compare the two groups. Results A total of 283 patients were included in the transperineal group and 513 in the transrectal group. The analysis of a learning curve for the transperineal method showed lower complications rates comparing the first six months of TPPB procedures (group 1); The complication rate for TPPB was lower than that of TRPB (55.1% versus 81.9%, respectively; p<0.01). TPPB showed specifically lower rates of hematuria (48.8% versus 66.3%;p<0.001) and rectal bleeding(3.5% versus 18.1%; p<0.001). There were no cases of prostatitis after transperineal biopsies and three cases (0.6%) after transrectal procedures. Conclusions We evidenced the learning curve for performing the transperineal biopsy, with a lower rate of complications for the experienced team, after 142 cases after 6 months of practice. The lower complication rate of TPPB and the absence of infectious prostatitis imply a safer procedure when compared to TRPB.

Resumo: O objetivo deste artigo foi identificar o papel da liberalização do comércio de alimentos na segurança alimentar tomando como base dados científicos da literatura internacional e visando elucidar pontos positivos ou negativos. Uma revisão sistemática foi realizada nas bases Web of Science e Scopus no período de 2015 a 2019. Foram identificados dezesseis trabalhos, observando os critérios de inclusão e exclusão estabelecidos. Foi possível constatar que a literatura sobre o tema em questão permanece ambígua, não havendo consenso sobre os reais ganhos ou perdas. A natureza e a magnitude do efeito da liberalização na segurança alimentar dependem de vários fatores, como o grau de adaptabilidade dos pobres às mudanças nas condições econômicas; o grau de exposição dos países às importações de alimentos; a presença de condições iniciais favoráveis; as medidas de acompanhamento; e o horizonte temporal considerado na pesquisa.

Abstract: This paper aimed to identify in the international literature on food security the scientific results about the role of trade liberalization in the same. A systematic review was used in the Web of Science and Scopus databases from 2015 to 2019. It was identify 16 studies according the inclusion and exclusion criteria. It was found that the literature on the issues in question remains ambiguous, with no consensus on the real gains or losses. The nature and magnitude of the effect of liberalization on food security depends on several factors, such as: the degree of adaptability of the poor to changes in economic conditions; the degree of exposure of countries to food imports; the presence of favorable initial conditions; accompanying measures; and the time horizon considered in the research.

ABSTRACT CROPWAT is a model that uses water balance to study the water factor and productivity in production systems. In this sense, this study aimed to calibrate the CROPWAT for modeling rainfed and irrigated soybean production systems. Climate and soil data from a soybean-producing region in the south of Mato Grosso do Sul, Brazil, were used to implementing simulations in nine agricultural years, and crop shortfalls were calculated and compared with reference data. Statistical indices were applied to evaluate the performance of the model in its calibration. For validation, two field trials with 12 cultivars were implemented under irrigation and rainfed and the mean productivity in each water management was compared with the CROPWAT estimate by Student’s t-test. Accuracy (r) was 0.976 (“very strong”), precision (r2) was equivalent to 95.3%, and the indices of agreement (d) and performance (c) were considered excellent (0.95 and 0.93, respectively) in the calibration. Validation demonstrated that the hypothesis that CROPWAT correctly estimated soybean productivity under irrigated and rainfed systems cannot be rejected at 1 or 5% significance levels.

Abstract The oil from the fruit of peach palm or Pupunha (Bactris gasipaes) is an example of a material with low-cost and good antioxidant capacity. However, Conventional methods for measuring oil content are time-consuming, labor-intensive and use toxic chemicals. In this sense, the aim of this study was evaluated fast and non-destructive spectroscopy methods, such as Near Infrared (NIR) and Time-Domain Nuclear Magnetic Resonance (TD-NMR) (CPMG and ROSE pulse sequences), to quantify the oil content in pupunha flours collected in the amazon forest. For this, 93 samples were used and the results showed three distinct levels of oil in the samples: high, medium and low oil content. Furthermore, the determination coefficient (R2) reached values of 0.92, 0.92 and 0.70 for NIR, TD-NMR (ROSE) and TD-NMR (CPMG), respectively. Therefore, the NIR and TD-NMR (ROSE) methods demonstrate a higher prediction efficiency, with the NIR achieving 100% classification of the samples.

ABSTRACT. Wooden breast myopathy (WB) strongly affects the poultry industry mainly in terms of consumers rejection and economical loses, due to morphological changes in broiler muscle tissue and consequently low meat quality. The aim of this study is to evaluate the histomorphometry of muscle fibers of breast fillets of broilers with severity levels of WB myopathy. The histological evaluation considered 30 samples of the pectoralis major muscle and the level of WB myopathy (ten normal fillets, ten moderate fillets, and ten severe fillets). Fillets with a severe level of WB present low average fiber number, high average fiber diameter, low percentage of fibers with diameter of less than 20 µm, low percentage of fibers with diameter between 20 and 40 µm, and high percentage of fibers with diameter between 40 and 70 µm. Fiber cross-sectional area is greater in fillets affected by moderate and severe WB. Thus, fillets with a severe level of WB damage the muscle fiber structure and contribute more severely to the degenerative processes of breast meat.

ABSTRACT The objective of this study was to determine the energy values and metabolizability of different lipid sources in the diet of Japanese quail at the laying phase. The quail were distributed in a completely randomized design with ten replications of seven poultry per treatment, totaling six treatments: basal feed (control) and basal feed containing 10% soybean oil, corn oil, canola oil, sunflower oil, and poultry fat. The values of nitrogen-corrected apparent metabolizable energy (AMEn) and the metabolizability coefficient (MC%) were evaluated. No significant difference was found between the different lipid sources for AMEn (kcal/kg) and MC (%). The value of metabolizable energy corrected for nitrogen for soybean oil was 8,790 kcal/kg; 8,773 kcal/kg for corn oil; 8,784 kcal/kg for canola oil; 8,788 kcal/kg for sunflower oil; and 8,681 kcal/kg for poultry fat in laying Japanese quail. The digestibility coefficients were 93.88% for soybean oil, 93.53% for corn oil, 93.32% for canola oil, 93.74% for sunflower oil, and 93.06% for poultry fat.

Abstract This study aims to evaluate the residual effect of different lipid sources in the diet of Japanese quails (Coturnix japonica) in the rearing phase on the performance and egg quality in the initial phase of egg-laying. In the first stage, 400 Japanese quails aged 21 days were used, being distributed in a completely randomized experimental design, with five treatments and ten replicates of eight birds/replicate Treatments consisted of basal ration (BR) with 2.5% soybean oil; BR with 2.5% corn oil; BR with 2.5% cottonseed oil; BR with 2.5% sunflower oil; and BR with 2.5% canola oil. At 42 days, maintaining the initial design, all quails received a basal ration with soybean oil, in order to evaluate the residual effect of the previous phase on the performance and egg quality in the initial phase of egg-laying (43 - 84 days). The different lipid sources did not affect the performance of quails in the initial phase of production. For egg quality, yolk height, yolk diameter, yolk index, gravity, and Haugh unit (HU) showed better results in the treatment using sunflower oil. There was a residual effect of the use of lipid sources of vegetable origin in the rearing phase diet of Japanese quails on egg quality traits. Lipid sources from soybean, corn, cottonseed, canola, and sunflower seeds can be used as energy sources in the rearing diet of egg-laying quails for not being harmful to their initial performance. The longevity in egg production of quails fed with different lipid sources in the rearing phase was similar.

Resumo A pesquisa foi conduzida com objetivo de avaliar o efeito residual de diferentes fontes lipídicas na dieta de codornas japonesas (Coturnix japonica) na fase de recria sob o desempenho e a qualidade de ovos na fase inicial de postura. Na primeira etapa foram utilizadas 400 codornas japonesas com idade de 21 dias, as aves foram distribuídas em tratamentos seguindo um delineamento inteiramente casualizado com dez repetições, de oito aves, em cinco tratamentos: ração basal (RB) com 2,5% de óleo de soja, RB com 2,5 % de óleo de milho, RB com 2,5% de óleo algodão, RB com 2,5% de óleo de girassol e RB com 2,5% de óleo de canola. Aos 42 dias mantendo o delineamento inicial, todas aves receberam ração basal com óleo de soja, para que fosse avaliado o efeito residual da fase anterior sobre o desempenho e a qualidade dos ovos na fase inicial de postura (43 - 84 dias). As diferentes fontes lipídicas não afetaram o desempenho das aves na fase inicial de produção. Para a qualidade dos ovos, os parâmetros de altura, diâmetro e índice de gema, gravidade e UH foram melhores no tratamento com utilização de óleo de girassol. Houve efeito residual da utilização de fontes lipídicas de origem vegetal na dieta em fase de recria de codornas japonesas sobre as características da qualidade dos ovos. As fontes lipídicas oriundas das sementes de soja, milho, algodão, canola e girassol podem ser utilizadas como ingredientes energéticos na dieta de recria de codornas poedeiras por nâo serem prejudiciais ao desempenho inicial das aves. A longevidade na produção dos ovos das aves alimentadas com diferentes fontes lipídicas na fase de recria foi semelhante.

ABSTRACT Pulmonary aspiration of gastric residues during anesthesia is a potentially fatal complication for which no specific treatment is available. The primary way to prevent its occurrence in the context of elective surgeries is adherence to fasting protocols. However, some clinical conditions can prolong the gastric emptying time, and the risk of aspiration may exist despite adequate fasting. Recognizing the risk factors for gastroparesis allows the adoption of preventive methods and is the primary way to reduce morbidity and mortality from pulmonary aspiration. In this scenario, the anesthesiologist can investigate the gastric content by using ultrasound, adjust the anesthetic technique, and even postpone elective surgeries. Here, we describe incidental computed tomography finding of solid contents in the stomach of a patient without prior identification of the risk factors for gastroparesis. The patient underwent elective renal nodule ablation under general anesthesia after fasting for 9 hours. During the procedure, solid contents in the stomach were noted on computed tomography. Subsequently, it was discovered that the patient had been using semaglutide for 6 days and had not disclosed this information. Semaglutide use may represent a new and significant risk factor for anesthesia-related pulmonary aspiration. Until studies provide information on the appropriate perioperative management of patients using semaglutide, anesthesiologists need to adopt preventive measures to avoid aspiration. Awareness of this potential association and open communication among patients, physicians, and anesthesia teams are essential for enhancing patient safety.

ABSTRACT. The objective is to evaluate the effects of the inclusion of yerba mate in the diet on the yield and quality of chicken meat stored frozen for 120 days after slaughter. The birds were distributed in a completely randomized design, with four treatments, and eight replications with 25 birds each. The treatments consisted of providing a basal diet with 1, 2, 4, and 6 g kg-1 of ground dehydrated Yerba mate. At slaughter, temperature, pH, and carcass yield were measured. 120 days after meat freezing, measurements of pH, colorimetry, cooking weight loss (CWL), shear force, and water retention capacity were estimated. The parameters evaluated after slaughter showed regression effects on breast and drumstick temperature. Breast temperature showed a decreasing linear effect (R2=0.61). For the variable thigh temperature, there was a negative quadratic effect (R2=0.66). The quality characteristics of breast and drumstick evaluated 120 days after freezing showed an increasing linear effect of drumstick CWL (R2=0.38). Yerba mate can be included in up to 6 g kg-1 in chicken feed without changing pH, color, and meat tenderness after 120 days of freezing, maintaining carcass and cut yields.

Abstract This study aims to describe a case series of patients who underwent thoracic duct embolization (TDE) to treat traumatic iatrogenic chylothorax (TIC). Three patients were included: Case #1, a 49-year-old woman with follicular lymphoma developed a TIC following video-assisted thoracoscopic surgery to resect a solid right paravertebral mass and was treated with TDE using microcoils and N-butyl cyanoacrylate (NBCA) glue. Case #2, a 68-year-old man with cardiac amyloidosis developed a TIC following heart transplantation and was treated with TDE using microcoils and ethylene vinyl alcohol copolymer. Case#3: A 6-year-old patient with congenital heart disease developed a TIC following a Fontan procedure and was treated with TDE using NBCA glue. All lesions were identified during lymphangiography and TDE was successfully performed in all cases. TDE is a safe and valuable technique that provides minimally invasive treatment for TCI.

A EDT é uma técnica segura e valiosa, que pode oferecer um tratamento minimamente invasivo em casos de QI.

Abstract A 100-year-old male patient was admitted with a ruptured abdominal aortic aneurysm due to type IA endoleak. Given the proximity of the ruptured site to the superior mesenteric artery (SMA) and renal arteries, a ChEVAR was indicated. Catheterization of the target visceral vessels was a challenging procedural step because of an intensely tortuous thoracic aorta. This hostile aortic anatomy also inhibited exchange for a super stiff guide-wire and selective cannulation with the diagnostic catheter was repeatedly lost when guidewire exchange was attempted. To overcome this issue, a 5 x 40 mm balloon catheter was placed 3cm into the target arteries. The balloon was then inflated below the nominal pressure limit enabling safe exchange for a super stiff guidewire and placement of three 90-cm long 7Fr guiding sheaths. The procedure was thus safely performed with deployment of an aortic extension and the bridging stents.

Resumo Um paciente de 100 anos foi diagnosticado com um aneurisma de aorta abdominal roto por um endoleak 1A. Pela proximidade do ponto de ruptura com a artéria mesentérica superior (AMS) e as artérias renais, um ChEVAR foi indicado. A cateterização das artérias-alvo foi um passo desafiador pela intensa tortuosidade da aorta torácica. Essa anatomia aórtica hostil também impediu a troca por um fio-guia extra-rígido, e a cateterização seletiva foi repetidamente perdida quando a troca de fio-guia foi tentada. Para superar essa dificuldade, um cateter balão 5mm x 40mm foi posicionado nas artérias-alvo. O balão foi, então, insuflado abaixo da pressão nominal, permitindo uma troca segura do fio-guia por um fio-guia extra-rígido e o posicionamento de três bainhas longas 7Frx 90cm. Assim, o procedimento foi executado de forma segura, com o implante de uma extensão aórtica e dos stents recobertos.

ABSTRACT Objective To describe the clinical, bronchoscopic, diagnostic, and therapeutic aspects between children and adults. Methods This retrospective study compared the clinical and bronchoscopic characteristics of adults and children who underwent bronchoscopy for suspected foreign body aspiration. Data on sex, outpatient or emergency origin, bronchoscopy results, characteristics of the aspirated foreign body, and complications were analyzed. Results In total, 108 patients were included in the analysis, with foreign body aspiration diagnosed in 69% of patients (30 children and 44 adults). In 91% of patients, there was a clinical history suggestive of aspiration. The mean age of the adults was 65.89 (±19.75) years, and that of the children was 2.28 (±1.78) years. Most of the children were under 3 years of age (80%), while adults were mostly 70 years of age or older (54.5%). Emergency care was more common among children than adults. The most common foreign bodies found in both age groups were organic bodies, primarily seeds. The most frequent locations of foreign bodies were the lobar bronchi in adults and the main bronchi in children. Flexible bronchoscopy is the primary method for diagnosis and treatment. Transient hypoxemia occurred particularly frequently in children (5%). Conclusion Foreign body aspiration, particularly that involving seeds, is more common in the extremes of age. A clinical history suggestive of aspiration is crucial in determining the need for bronchoscopy, which should be performed as early as possible. Flexible bronchoscopy is an effective and safe diagnostic technique.

ABSTRACT Objective To describe the radiological characteristics of hepatocellular carcinoma (HCC) lesions that achieved a complete response following drug-eluting bead transarterial chemoembolization (DEB-TACE) preceding liver transplantation. Methods This single-center case-control study enrolled patients with hepatocellular carcinoma who underwent neoadjuvant DEB-TACE therapy, were followed up with contrast-enhanced magnetic resonance imaging or computed tomography, and were successively evaluated according to the modified Response Evaluation Criteria in Solid Tumors. The HCCs were divided into two groups based on their diameter (Group A: ≤3cm; Group B: 3cm). Viability was assessed using the Kaplan-Meier method according to tumor size categories. The relationship between tumor variables was analyzed using bivariate Cox regression. Results Three-hundred and twenty-eight patients with 667 hepatocellular carcinomas who underwent their first DEB-TACE session were enrolled. A total of 105 hepatocellular carcinomas in 59 patients exhibited complete response after the initial DEB-TACE session and were divided into Group A (92 HCCs) and Group B (13 HCCs). The diameter in Group A decreased significantly compared to the pre-procedure size until the second assessment (p<0.001), with no subsequent reduction in diameter, despite maintaining a complete response. In Group B, the reduction in diameter remained significant compared with the initial value until the sixth imaging evaluation (p=0.014). The average reduction was 45.1% for Group B and a maximum of 14.9% in Group A. Conclusion HCCs >3cm exhibited a greater reduction in size and a longer time to recurrence. HCCs ≤3cm had a shorter relapse time. The recurrence rates were similar. These findings may aid in planning for liver transplantation.
