RESUMO

BACKGROUND: Colorectal cancer is the third most common type of cancer in Brazil, despite the availability of screening methods that reduce its risk. Colonoscopy is the only screening method that also allows therapeutic procedures. The proper screening through colonoscopy is linked to the quality of the exam, which can be evaluated according to quality criteria recommended by various institutions. Among the factors, the most used is the Adenoma Detection Rate, which should be at least 25% for general population. AIMS: To evaluate the quality of the screening colonoscopies performed in a quarternary private Brazilian hospital. METHODS: This is a retrospective study evaluating the quality indicators of colonoscopies performed at a private center since its inauguration. Only asymptomatic patients aged over 45 years who underwent screening colonoscopy were included. The primary outcome was the Adenoma Detection Rate, and secondary outcomes included polyps detection rate and safety profile. Subanalyses evaluated the correlation of endoscopic findings with gender and age and the evolution of detection rates over the years. RESULTS: A total of 2,144 patients were include with a mean age of 60.54 years-old. Polyps were diagnosed in 68.6% of the procedures. Adenoma detection rate was 46.8%, with an increasing rate over the years, mainly in males. A low rate of adverse events was reported in 0.23% of the cases, with no need for surgical intervention and no deaths. CONCLUSIONS: This study shows that high quality screening colonoscopy is possible when performed by experienced endoscopists and trained nurses, under an adequate infrastructure.

RESUMO

Rhenium complexes show great promise as anticancer drug candidates. Specifically, compounds with a Re(CO)3(NN)(py)+ core in their architecture have shown cytotoxicity equal to or greater than that of well-established anticancer drugs based on platinum or organic molecules. This study aimed to evaluate how the strength of the interaction between rhenium(I) tricarbonyl complexes fac-[Re(CO)3(NN)(py)]+, NN = 1,10-phenanthroline (phen), dipyrido[3,2-f:2',3'-h]quinoxaline (dpq) or dipyrido[3,2-a:2'3'-c]phenazine (dppz) and biomolecules (protein, lipid and DNA) impacted the corresponding cytotoxic effect in cells. Results showed that fac-[Re(CO)3(dppz)(py)]+ has higher Log Po/w and binding constant (Kb) with biomolecules (protein, lipid and DNA) compared to complexes of fac-[Re(CO)3(phen)(py)]+ and fac-[Re(CO)3(dpq)(py)]+. As consequence, fac-[Re(CO)3(dppz)(py)]+ exhibited the highest cytotoxicity (IC50 = 8.5 µM for HeLa cells) for fac-[Re(CO)3(dppz)(py)]+ among the studied compounds (IC50 > 15 µM). This highest cytotoxicity of fac-[Re(CO)3(dppz)(py)]+ are probably related to its lipophilicity, higher permeation of the lipid bilayers of cells, and a more potent interaction of the dppz ligand with biomolecules (protein and DNA). Our findings open novel avenues for rational drug design and highlight the importance of considering the chemical structures of rhenium complexes that strongly interact with biomolecules (proteins, lipids, and DNA).

RESUMO

Traditional monitoring of asian soybean rust severity is a time- and labor-intensive task, as it requires visual assessments by skilled professionals in the field. Thus, the use of remote sensing and machine learning (ML) techniques in data processing has emerged as an approach that can increase efficiency in disease monitoring, enabling faster, more accurate and time- and labor-saving evaluations. The aims of the study were: (i) to identify the spectral signature of different levels of Asian soybean rust severity; (ii) to identify the most accurate machine learning algorithm for classifying disease severity levels; (iii) which spectral input provides the highest classification accuracy for the algorithms; (iv) to determine a sample size of leaves that guarantees the best accuracy for the algorithms. A field experiment was carried out in the 2022/2023 harvest in a randomized block design with a 6x3 factorial scheme (ML algorithms x severity levels) and four replications. Disease severity levels assessed were: healthy leaves, 25 % severity, and 50 % severity. Leaf hyperspectral analysis was carried out over a wide range from 350 to 2500 nm. From this analysis, 28 spectral bands were extracted, seeking to distinguish the spectral signature for each severity level with the least input dataset. Data was subjected to machine learning analysis using Artificial Neural Network (ANN), REPTree (DT) and J48 decision trees, Random Forest (RF), and Support Vector Machine (SVM) algorithms, as well as a traditional classification method (Logistic Regression - LR). Two different input datasets were tested for each algorithm: the full spectrum (ALL) provided by the sensor and the 28 spectral bands (SB). Tests with different sample sizes were also conducted to investigate the algorithms' ability to detect severity levels with a reduced sample size. Our findings indicate differences between the spectral curves for the severity levels assessed, which makes it possible to differentiate between healthy plants with low and high severity using hyperspectral sensing. SVM was the most accurate algorithm for classifying severity levels by using all the spectral information as input. This algorithm also provided high classification accuracy when using smaller leaf samples. This study reveals that hyperspectral sensing and the use of ML algorithms provide an accurate classification of different levels of Asian rust severity, and can be powerful tools for a more efficient disease monitoring process.

RESUMO

Background and study aims Recurrent biliary stent occlusion and tumor ingrowth remain a major concern among patients with malignant biliary obstruction (MBO) with significant impact on patient morbidity and survival. Intraductal radiofrequency ablation (RFA) has emerged as a promising treatment that seeks to extend stent patency. This study aimed to evaluate the impact of RFA on overall survival (OS) and stent patency among patients with unresectable MBO. Methods A comprehensive search of electronic databases was performed for randomized controlled trials (RCTs) comparing RFA plus biliary stent (RFA+S) versus biliary stent alone (S-alone). Outcomes assessed included overall survival, stent patency, and adverse events (AEs) with mean difference (MD) calculated from pooled proportions. Subgroup analyses were performed for hilar strictures and cholangiocarcinoma (CCA). Results Six RCTs (n=439 patients) were included and demonstrated improved survival among patients who received RFA+S (MD 85.80 days; 95% confidence interval [CI] 35.02-136.58; I 2 =97%; P <0.0009). The pooled MD for total stent patency was 22.25 days (95% CI 17.38-61.87; I 2 =97%; P =0.27). There was no difference in AEs between RFA+S vs S-alone ( P >0.05). On subgroup analyses, RFA+S was associated with improved stent patency (MD 76.73 days; 95% CI 50.11-103.34; I 2 =67%; P <0.01) and OS (MD 83.14 (95% CI 29.52-136.77; I 2 =97%; P <0.01] for CCA. For hilar strictures, stent patency was improved among patients with RFA+S [MD 83.71 days (95% CI 24.85-142.56; I 2 =84%; P <0.01]. Conclusions RFA+S improved OS in the treatment of MBO when compared with S-alone. Moreover, the RFA therapy prolonged stent patency in hilar strictures and CCA, with similar rates of AEs.

RESUMO

Acinetobacter spp. are one of the main pathogens responsible for healthcare-associated infections and are associated with high rates of morbidity and mortality globally, mainly because of their high capacity to present and develop resistance to antimicrobials. To identify species of the Acinetobacter and their resistance profiles from samples collected from hospitalized patients, health professionals and hospital environmental sources in the intensive care units of different public reference hospitals in Porto Velho City, Rondônia, Western Brazilian Amazon. Isolates were identified using microbiological and molecular techniques. The antimicrobial susceptibility profile was determined by disk diffusion. A total of 201 Acinetobacter spp. isolates were identified, of which 47.3% originated from hospital structures, 46.8% from patients and 6% from healthcare professionals. A. baumannii and A. nosocomialis were the most prevalent, with frequency of 58.7% and 31.8%, respectively. Regarding the susceptibility profile, it was observed that 56.3% were classified as multidrug-resistant and 76.2% of the samples belonging to A. baumannii were resistant to carbapenems. In contrast, 96.9% were susceptible to polymyxin B and 91.3% to doxycycline. The data presented here can be used to guide and strengthen the control of multidrug-resistant infections caused by Acinetobacter spp., in addition to improving providing information from a traditionally unassisted region of Brazil.

RESUMO

INTRODUCTION: Adverse events (AE) after endoscopic retrograde cholangiopancreatography (ERCP) are not uncommon and post-ERCP acute pancreatitis (PEP) is the most important one. Thermal injury from biliary sphincterotomy may play an important role and trigger PEP or bleeding. Therefore, this study evaluated the outcomes of 2 electric current modes used during biliary sphincterotomy. METHODS: From October 2019 to August 2021, consecutive patients with native papilla undergoing ERCP with biliary sphincterotomy were randomized to either the pure cut or endocut after cannulation. The primary outcome was PEP incidence. Secondary outcomes included intraprocedural and delayed bleeding, infection, and perforation. RESULTS: A total of 550 patients were randomized (272 pure cut and 278 endocut). The overall PEP rate was 4.0% and significantly higher in the endocut group (5.8% vs 2.2%, P = 0.034). Univariate analysis revealed >5 attempts ( P = 0.004) and endocut mode ( P = 0.034) as risk factors for PEP. Multivariate analysis revealed >5 attempts ( P = 0.005) and a trend for endocut mode as risk factors for PEP ( P = 0.052). Intraprocedural bleeding occurred more often with pure cut ( P = 0.018), but all cases were controlled endoscopically during the ERCP. Delayed bleeding was more frequent with endocut ( P = 0.047). There was no difference in perforation ( P = 1.0) or infection ( P = 0.4999) between the groups. DISCUSSION: Endocut mode may increase thermal injury leading to higher rates of PEP and delayed bleeding, whereas pure cut is associated with increased intraprocedural bleeding without clinical repercussion. The electric current mode is not related to perforation or infection. Further RCT assessing the impact of electric current on AE with overlapping preventive measures such as rectal nonsteroidal anti-inflammatory drugs and hyperhydration are needed. The study was submitted to the Brazilian Clinical Trials Platform ( http://www.ensaiosclinicos.gov.br ) under the registry number RBR-5d27tn.

RESUMO

CONTEXT: Studies that analyze the temporal trend and spatial clustering of medical education indicators are scarce, especially in developing countries such as Brazil. This analysis is essential to subsidize more equitable policies for the medical workforce in the states and regions of Brazil. Thus, this study aimed to analyze the temporal trend and identify spatial clusters of medical education indicators in Brazil disaggregated by public and private education, states, and regions. METHODS: A time-series ecological study was conducted using data from the Higher Education Census of the Ministry of Education from 2010 to 2021. The study analyzed vacancy density indicators of active and former students/100,000 population, disaggregated by public and private education, 27 states, and 5 regions in Brazil. Prais-Winsten regression was used for trend analyses of indicators. Hot Spot Analysis (Getis-Ord Gi*) was used to identify spatial clusters of indicators. RESULTS: The number of medical schools increased by 102.2% between 2010 and 2021. A total of 366 medical schools offered 54,870 vacancies at the end of 2021. Vacancy density and active and former students increased significantly in the period, but this increase was greater in private institutions. Most states and regions showed an increasing trend in the indicators, with higher increase percentages in private than in public schools. Hot spot spaces changed over time, concentrated in the southeast, center-west, and north at the end of 2021. Medical education remains uneven in Brazil, with a low provision in regions with low socioeconomic development, academic structure, and health services, represented by regions in the north and northeast. CONCLUSIONS: There is a growing trend in medical education indicators in Brazil, especially in the private sector. Spatial clusters were found predominantly in the southeast, center-west, and north. These results indicate the need for more equitable medical education planning between the regions.

RESUMO

The World Health Organization (WHO) created the concept of Integrated Care for Older People and one of its constructs is intrinsic capacity (IC). The study aimed to carry out a screening with the tools designated by the WHO to assess the IC domains and whether they can be used as indicators for decision-making on integrated care for older people based on risk categorization. The interaction between the risk category and the domain scores was verified. One hundred and sixty three (163) community-dwelling older people of both genders were evaluated. Domains assessed: cognitive, psychological, vitality, locomotion, and sensory. Scores indicating a low, moderate and high risk were assigned to each domain. For all domains, there were individuals in all risk groups. Effect of risk on the domains: cognitive [χ2(2) = 134.042; p < 0.001], psychological [χ2(2) = 92.865; p < 0.001], vitality [χ2(2) = 129.564; p < 0.001], locomotion [χ2(2) = 144.101; p < 0.001], and sensory [χ2(2) = 129.037; p < 0.001]. Scores of the CI domains were affected by the risk category. There were individuals in all risk groups, demonstrating the importance of screening as a public health strategy, making it possible to know which risk category each elderly person belongs to and thus develop strategies in the short-, medium- and long-term.

RESUMO

Major depressive disorder (MDD) etiology is still not completely understood, and many individuals resist the traditional treatments. Chronic exposure to stressful events can contribute to development and progression and be involved in biological changes underlying MDD. Among the biological mechanisms involved, inflammatory changes and oxidative balance are associated with MDD pathophysiology. Quetiapine, a second-generation antipsychotic, induces a better therapeutic response in individuals refractory to traditional treatments. The main objectives of this research were as follows: to evaluate the effect of chronic mild stress (CMS) on depressive-like behaviors, oxidative stress, and inflammation in adult rats; to evaluate the possible antidepressant, antioxidant, and anti-inflammatory effects of quetiapine. The animals were submitted to CMS protocols. At the end of the CMS, the animals were submitted to a chronic treatment for 14 days with the following drugs: quetiapine (20 mg/kg), imipramine (30 mg/kg), and escitalopram (10 mg/kg). At the end of the treatments, the animals were evaluated in the open field tests, anhedonia (splash test), and forced swimming. The animals were euthanized after the behavioral tests, and serum samples were collected. Myeloperoxidase (MPO) activity and interleukin-6 (IL-6) levels were analyzed. CMS induced an increase in depressive-like behaviors, and quetiapine significantly reduced these behaviors. MPO activity and IL-6 levels increased in the serum of animals submitted to CMS. Quetiapine significantly reduced MPO activity and IL-6 levels. These results corroborate other evidence, indicating that chronic stress is a relevant phenomenon in the etiology of depression and suggesting that quetiapine induces an antidepressant effect because it reduces oxidative and inflammatory mechanisms.

RESUMO

OBJECTIVES: Endoscopic vacuum therapy (EVT) possesses a unique mechanism of action providing a less invasive alternative for the management of transmural gastrointestinal defects (TGID). This study evaluates the efficacy and safety of a novel homemade EVT (H-EVT) for the treatment of TGID. METHODS: Retrospective multicenter study including patients who underwent H-EVT for TGID between January 2019 and January 2022. Main outcomes included technical and clinical success as well as safety outcomes. Subgroup analyses were included by defect location and classification. Logistic regression analyses were performed to determine predictors for successful closure. RESULTS: A total of 144 patients were included. Technical success was achieved in all patients, with clinical success achieved in 88.89% after a mean of 3.49 H-EVT exchanges over an average of 23.51 days. After excluding 10 cases wherein it was not possible to achieve negative pressure, successful closure occurred in 95.52% of patients. Time to clinical success was less for defects caused by endoscopic (hazard ratio [HR] 0.63; 95% confidence interval [CI] 0.33-1.20) compared to surgical procedures and for patients with simultaneous intracavitary and intraluminal H-EVT placement (HR 0.70; 95% CI 0.55-0.91). Location and classification of defect did not impact clinical success rate. Simultaneous placement of both an intraluminal and intracavitary H-EVT (odds ratio 3.08; 95% CI 1.19-7.95) was a significant predictor of clinical success. Three device-related adverse events (2.08%) occurred. CONCLUSIONS: The use of the H-EVT is feasible, safe, and effective for the management of TGID.

RESUMO

OBJETIVO: Avaliar o efeito de uma intervenção educativa no conhecimento dos profissionais de saúde acerca da prevenção de infecção de pele em lesões por queimaduras em crianças e adolescentes internados em um centro de tratamento de queimados. MÉTODO: Trata-se de um estudo de intervenção quase-experimental com abordagem quantitativa, desenvolvido no período de agosto de 2022 a janeiro de 2023. Participaram do estudo profissionais de todos os turnos que estavam de plantão no momento da intervenção, previamente agendada. Os dados da pesquisa foram coletados por meio de entrevistas individuais, utilizando-se um instrumento composto por questões fechadas. Para a análise dos dados, utilizaram-se números e porcentagens e o teste estatístico McNemar para amostras pareadas, considerando o nível de significância de 5%. RESULTADOS: Houve melhora no conhecimento dos profissionais após a intervenção imediata se comparada ao pré-teste com nível de significância, entre eles: conceito de choque séptico (p=0,004), conceito de sepse (p=0,012), critério para a identificação de sepse no paciente queimado (p=0,002) e situações impeditivas de ato cirúrgico precoce (p=0,001). Após três meses da intervenção, notou-se que não houve retenção desse conhecimento pela equipe multiprofissional. CONCLUSÕES: Salienta-se a importância da educação permanente em saúde para os profissionais. Estas ações, além de melhorar o conhecimento, contribuem para o aprimoramento da qualidade e segurança da assistência à saúde com ações pautadas na prevenção de infecção de pele em queimadura.


OBJECTIVE: To evaluate the effect of an educational intervention on the knowledge of health professionals about the prevention of skin infections in burn injuries in children and adolescents admitted to a burn treatment center. METHODS: This is a quasi-experimental intervention study with a quantitative approach, developed from August 2022 to January 2023. Professionals from all shifts who participated in the study were on duty at the time of the previously scheduled intervention. Research data were collected through individual interviews, using an instrument composed of closed questions. For data analysis, numbers and percentages and the McNemar statistical test for paired samples were used, considering a significance level of 5%. RESULTS: There was an improvement in professionals' knowledge after the immediate intervention compared to the pre-test with a level of significance, including: concept of septic shock (p=0.004), concept of sepsis (p=0.012), criterion for the identification of sepsis in burn patients (p=0.002) and situations that prevent early surgery (p=0.001). Three months after the intervention, it was noted that there was no retention of this knowledge by the multidisciplinary team. CONCLUSIONS: The importance of continuing health education for professionals is highlighted. These actions, in addition to improving knowledge, contribute to improving the quality and safety of health care with actions aimed at preventing skin infections in burns.

RESUMO

The industrial seed treatment (IST) of soybeans is an economically recommended technique in agricultural production, providing protection against pests and initial pathogens. However, the real effects of pesticides about the quality of soybean seeds are still little known, since the adoption of the system is still recent by soybean farmers. The objective of this work was to evaluate the physiological quality of soybean seeds, treated or not, with insecticide/ fungicide new mixtures and stored for 240 days in a non-controlled and controlled environment. The completely randomized design was used, distributed in a 5 x 2 x 6 factorial scheme with four replications. The plot treatments consisted of soybean seeds belonging to the cultivar M - 7739 IPRO, treated with six different insecticide/ fungicide mixtures {(Cruiser®); (Amulet®); (MaximAdvanced®); (Cruiser®+ MaximAdvanced®); (MaximAdvanced® + Amulet®); (untreated control)}, stored in two environments {(laboratory ­ without control and cold room ­ with control (10 ± 2 ºC,45± 2% UR)} for eight months of storage with five evaluation times (0; 60; 120; 180 and 240days). The following tests were carried out: water content, germination, first count, seedling length and seedling dry mass. It was found that the chemical treatments negatively affect the germination potential of seeds, especially after 120 days of storage, regardless of the environment.Thiamethoxamand Thiamethoxam + Metalaxil; Tabendazole; Fludioxonil after storage provided the biggest reductions in seed viability and vigor after 240 days of storage. The cold room environment provides better conditions for the conservation of the germinative potential of soybean seeds.


O tratamento industrial de sementes (TIS) de soja é uma técnica economicamente recomendada na produção agrícola, proporcionando proteção contra pragas e patógenos iniciais. No entanto, os reais efeitos dos agrotóxicos sobre a qualidade das sementes de soja ainda são pouco conhecidos, visto que a adoção do sistema ainda é recente pelos sojicultores. Objetivou-se com este trabalho avaliar a qualidade fisiológica das sementes de soja, tratadas ou não, com novas misturas de inseticidas/fungicidas, e armazenadas por 240 dias, em diferentes ambientes. O delineamento experimental utilizado foi inteiramente casualizado, distribuído em esquema fatorial 5 x 2 x 6, com quatro repetições. Os tratamentos das parcelas foram constituídos de sementes de soja pertencentes à cultivar M ­ 7739 IPRO, tratadas com seis diferentes misturas produtos de inseticida/fungicida {(Cruiser® - Tiametoxam ­ 200 mL + Bio Cromo ­ 100 mL); (Amulet® - Fipronil - 100 mL + Bio Cromo ­ 100 mL); (MaximAdvanced® - Metalaxil-M; Tabendazol; Fludioxonil ­ 100 mL + Bio Cromo ­ 100 mL ); (Cruiser® - Tiametoxam ­ 200 mL + MaximAdvanced® - Metalaxil-M; Tiabendazol; Fludioxonil ­ 100 mL + Bio Cromo ­ 100mL ); (MaximAdvanced® - Metalaxil-M; Tabendazol; Fludioxonil ­ 100 mL + Amulet® - Fipronil - 100 mL + BioCromo ­ 100mL); (controle não tradada)}, armazenadas em dois ambientes {(laboratório ­ sem controle e câmara fria ­ com controle (10 ± 2 ºC,45± 2% UR)} durante oito meses de armazenamento, com cinco tempos de avaliações (0; 60; 120; 180 e 240dias). Os seguintes testes foram realizados: teor de água, germinação, primeira contagem, comprimento das plântulas, massa seca de plântulase índice de velocidade de emergência. Verificou-se que o ambiente de câmara fria proporciona melhores condições para a conservação do potencial germinativo das sementes de soja. Os tratamentos químicos interferem negativamente no potencial germinativo das sementes, sobretudo após 120 dias de armazenamento, independente do ambiente. Tiametoxam e Tiametoxam + Metalaxil; Tabendazol; Fludioxonil após o armazenamento proporcionaram as maiores reduções da viabilidade e vigor das sementes após 240 dias de armazenamento. O ambiente de câmara fria proporciona melhores condições para a conservação do potencial germinativo das sementes de soja.

RESUMO

BACKGROUND: The present study aimed to evaluate the effects of hot smoking and liquid smoke on process yield, physicochemical properties, microbiological parameters, fatty acid profile, benzo(a)pyrene levels, and sensory profile of Pantanal yacare tail fillets. The fillets were subjected to two types of smoking processes: hot smoking and liquid smoke flavoring. RESULTS: The process yield of liquid-smoked fillets was higher (69.8%) compared to hot-smoked fillets (58.0%). All fillets were with good microbiological quality and low benzo(a)pyrene levels and were well accepted by consumers. The hot-smoked fillets and the liquid-smoked fillets presented 456.2 and 589.7 g kg-1 moisture, 262.3 and 263.7 g kg-1 crude protein, 218 and 85 g kg-1 total lipids, and 26.0 and 20.9 g kg-1 ash, respectively. The major fatty acids identified in the smoked tail fillets were palmitic, stearic, oleic, and linoleic acids. CONCLUSION: The liquid-smoked fillets had lower lipid content, and higher process yield because of lower losses; thus, they proved to be more advantageous and practical to obtain than the hot-smoked fillets. © 2022 Society of Chemical Industry.

RESUMO

INTRODUCTION: To investigate the influence of a training of mobility, gait speed and postural balance of pelvic floor muscles (PFM). METHODS: A single-arm clinical trial study was approved and registered at the Brazilian Clinical Trials Registry (RBR-4rxhd4). Eighteen women over the age of 60 with pelvic floor dysfunction complaints were subjected to 10 sessions of functional electrical stimulation and digital palpation of PFM. Mobility and gait speed were evaluated by the Timed up and Go and the 10-m walk tests respectively. Standing balance was evaluated using a force plate. RESULTS: No significant differences were found in mobility, gait speed, and standing balance. PFM contraction worsened mobility, gait speed, and standing balance performance. CONCLUSIONS: The training protocol enhanced PFM strength and endurance, but the improved ability to recruit PFM did not positively affect balance, mobility, and gait speed.

RESUMO

Endoscopic ultrasound (EUS)-guided therapeutic procedures have become increasingly common in clinical practice. The development of EUS-guided fine needle aspiration cytology led to the concept of interventional EUS. However, it carries a considerable risk of adverse events (AEs), which occur in approximately 23% of the procedures performed for the drainage of pancreatic fluid collections and 2.5-37.0% of those performed for drainage of the biliary tract. Although the vast majority of AEs occurring after EUS-guided drainage are mild, a deep understanding of such events is necessary for their appropriate management. Because EUS-guided drainage is a novel procedure, there have been few studies of the topic. To our knowledge, this is the first narrative review that focuses on the management and resolution of AEs occurring after EUS-guided drainage of pancreatic fluid collections or the biliary tract. We also include an explanatory video.
