RESUMO
Trypanosoma cruzi (T. cruzi) causes Chagas, which is a neglected tropical disease (NTD). WHO estimates that 6 to 7 million people are infected worldwide. Current treatment is done with benznidazole (BZN), which is very toxic and effective only in the acute phase of the disease. In this work, we designed, synthesized, and characterized thirteen new phenoxyhydrazine-thiazole compounds and applied molecular docking and in vitro methods to investigate cell cytotoxicity, trypanocide activity, nitric oxide (NO) production, cell death, and immunomodulation. We observed a higher predicted affinity of the compounds for the squalene synthase and 14-alpha demethylase enzymes of T. cruzi. Moreover, the compounds displayed a higher predicted affinity for human TLR2 and TLR4, were mildly toxic in vitro for most mammalian cell types tested, and LIZ531 (IC50 2.8 µM) was highly toxic for epimastigotes, LIZ311 (IC50 8.6 µM) for trypomastigotes, and LIZ331 (IC50 1.9 µM) for amastigotes. We observed that LIZ311 (IC50 2.5 µM), LIZ431 (IC50 4.1 µM) and LIZ531 (IC50 5 µM) induced 200 µg/mL of NO and JM14 induced NO production in three different concentrations tested. The compound LIZ331 induced the production of TNF and IL-6. LIZ311 induced the secretion of TNF, IFNγ, IL-2, IL-4, IL-10, and IL-17, cell death by apoptosis, decreased acidic compartment formation, and induced changes in the mitochondrial membrane potential. Taken together, LIZ311 is a promising anti-T. cruzi compound is not toxic to mammalian cells and has increased antiparasitic activity and immunomodulatory properties.

BACKGROUND: Studies indicate that mental practice can be an adjuvant rehabilitation, improving motor functions. AIM: To synthesize the evidence on the intervention with the mental practice for the rehabilitation of the upper limb after stroke in the context of a dependent task. METHODS: The review was registered on the PROSPERO with protocol number: CRD42020166624. We searched the PubMed, Medline, Embase, Central, PEDro, and Web of Science from randomized clinical trials from 1975 to 2022. A literature review was conducted with 13 studies that synthesized findings on mental practice such as adjuvant rehabilitation in the recovery of the upper limb after stroke based on Fugl-Meyer Assessment (FMA) Motor and action research arm test (ARAT) scores. RESULTS: The sample size was 232 were part of the intervention group and 180 of the control group. The findings no showed results in favor of mental practice after stroke accordingly to ARAT and FMA Motor scores (P > 0.05). CONCLUSION: Current evidence does not support the use of the mental practice to increase the recovery of the upper limb after stroke, although the evidence is conflicting for some aspects of the technique.
RESUMO
Introduction Supracricoid laryngectomy (SCL CHEP) removes â¼ 70% of the larynx, resulting in structural rearrangement and modification of the swallowing mechanism, promoting chronic dysphagia. One of the consequences of this new physiology is the formation of pharyngeal residues that can increase the possibility of aspiration. The formation of residues after SCL CHEP, its functional consequences, and its influence on quality of life (QOL) is still poorly described in the literature. Objective To investigate and compare the association between self-reported QoL and objective assessments of swallowing function in patients undergoing SCL CHEP. Methods A cross-sectional study was performed from 2018 to 2020 in a reference service for head and neck surgery in Brazil. A total of 860 swallowing videofluoroscopy images were evaluated using the Penetration and Aspiration Scale (PAS) and Dynamic Imaging Grade of Swallowing Toxicity (DIGEST). Results In a group of 86 patients, there was a significant relationship between oncological staging and the global ( p < 0.001) and total ( p = 0.002) QoL domains. There was a negative correlation between the DIGEST scale and the emotional domain of the QoL protocol ( p = 0.045). The swallowing function proved to be relevant for QoL. Conclusion The PAS scale did not show any correlation with QoL. The functional performance of swallowing according to the DIGEST scale was coherent with the QOL scores. It is suggested that the residue may be a more relevant aspect for QoL than the aspiration, making DIGEST a promising tool in the assessment of dysphagic patients.

RESUMO
OBJECTIVE: To describe the correlation between the residues, their anatomical location and the presence of laryngotracheal penetration and aspiration in patients after supracricoid laryngectomy undergoing cricohyoidoepiglotopexy reconstruction. METHODS: This study included 70 patients treated by supracricoid laryngectomy with cricohyoidoepiglotopexy reconstruction in a referral national cancer hospital. The patients were submitted to swallowing videofluoroscopy, and the findings were classified by the penetration and aspiration scale. The images were described observing the presence or absence of residues and their anatomical location. RESULTS: The prevalence of penetration in this study was 68.6% and aspiration was 34.3%. An association was found between the presence of residue on the tongue (p=0.005), posterior pharyngeal wall (p=0.013), pyriform recesses (p=0.002), valecula (p=0.061), and laryngeal penetration. The residue in the upper esophageal sphincter (p=0.039) was associated with the occurrence of laryngotracheal aspiration. CONCLUSION: Patients undergoing supracricoid laryngectomy with cricohioidoepiglotopexy reconstruction have food residues in different anatomical regions after swallowing. Penetration was associated with the presence of residues on the base of the tongue and posterior pharyngeal wall. Aspiration was associated with the presence of residues in the upper esophageal sphincter.

PURPOSE: This study aimed to evaluate late and asymptomatic patients after open partial horizontal laryngectomy (OPHL), investigating the clinical-surgical and socio-demographic factors associated with aspiration and severe dysphagia. METHODS: One-thousand videofluoroscopic swallowing studies were performed in 100 asymptomatic patients in the late period after OPHL(median 6.5 years). Aspiration and severe dysphagia were, respectively, assessed by the Penetration-Aspiration scale (PAS) and by the Dynamic Imaging Grade of Swallowing Toxicity (DIGEST) classification. Associated factors were investigated by multivariate logistic regressions. RESULTS: 34% (95% CI 24.3-47.6%) of patients presented aspiration and 23% (95% CI 15.3-34.6%) had severe or life-threatening dysphagia (DIGEST grades 3-4). On logistic regression, the presence of aspiration was associated with lower preoperative serum albumin (odds ratio [OR]: 0.22; 95% CI 0.07-0.64; p = 0.005, for each 1 g/dL increment); a greater weight loss in early postoperative period (OR: 1.19, 95% CI 1.05-1.35; p = 0.008, for each 1 kg loss); older age at surgery (OR: 1.08; 95% CI 1.01-1.17, for each 1-year older); and with the presence of diabetes (OR: 5.16; 95% CI 1.09-27.47; p = 0.039). CONCLUSION: Deglutition abnormalities are frequent in asymptomatic patients later after OPHL. Older patients, with lower preoperative serum albumin levels, with greater postoperative weight loss, and with diabetes compose the clinical profile at risk for having worse swallowing function in the late period after OPHL.

Chagas disease causes more deaths in the Americas than any other parasitic disease. Initially confined to the American continent, it is increasingly becoming a global health problem. In fact, it is considered to be an "exotic" disease in Europe, being virtually undiagnosed. Benznidazole, the only drug approved for treatment, effectively treats acute-stage Chagas disease, but its effectiveness for treating indeterminate and chronic stages remains uncertain. Previously, our research group demonstrated that 4-thiazolidinones presented anti-T. cruzi activity including in the in vivo assays in mice, making this fragment appealing for drug development. The present work reports the synthesis and anti-T. cruzi activities of a novel series of 4-thiazolidinones derivatives that resulted in an increased anti-T. cruzi activity in comparison to thiosemicarbazones intermediates. Compounds 2c, 2e, and 3a showed potent inhibition of the trypomastigote form of the parasite at low cytotoxicity concentrations in mouse splenocytes. Besides, all the 2c, 2e, and 3a tested concentrations showed no cytotoxic activity on macrophages cell viability. When macrophages were submitted to T. cruzi infection and treated with 2c and 3a, compounds reduced the release of trypomastigote forms. Results also showed that the increased trypanocidal activity induced by 2c and 3a is independent of nitric oxide release. Flow cytometry assay showed that compound 2e was able to induce necrosis and apoptosis in trypomastigotes. Parasites treated with the compounds 2e, 3a, and 3c presented flagellum shortening, retraction and curvature of the parasite body, and extravasation of the internal content. Together, these data revealed a novel series of 4-thiazolidinones fragment-based compounds with potential effects against T. cruzi and lead-like characteristics.

OBJECTIVE: To investigate the association between aging and the functional aspects of swallowing (laryngeal penetration and laryngotracheal aspiration) in individuals who underwent supracricoid laryngectomy in the late period and without complaints. METHODS: A total of 70 patients, 56 (80%) aged >60 years and 14 (20%) <60 years, under outpatient follow-up, after cancer treatment and with no complaints of swallowing, performed functional evaluation using the swallowing videofluoroscopy. Image classification was performed using the penetration-aspiration scale developed by Rosenbek. The χ2 test and logistic regression were applied to associate the age categories to the outcomes (penetration and aspiration). RESULTS: Patients aged over 60 years had a higher prevalence of penetration (24.29%) and aspiration (48.57%) than patients aged under 60 years. In this sample, aspiration was associated with age. Patients aged over 60 years were more likely to present penetration (27% more) during swallowing than patients under 60 years. Patients aged over 60 years had an approximately four-fold greater probability of laryngotracheal aspiration than patients aged under 60 years. CONCLUSION: In patients without complaints of swallowing in the late postoperative period of supracricoid laryngectomy, there is a greater probability of laryngotracheal aspiration in elderly aged over 60 years than in individuals under 60 years.

RESUMO Objetivo: Investigar a associação entre o envelhecimento e os aspectos funcionais da deglutição (penetração laríngea e aspiração laringotraqueal) em indivíduos submetidos à laringectomia supracricóidea no período tardio e sem queixas. Métodos: Setenta pacientes, sendo 56 (80%) >60 anos e 14 (20%) <60 anos, em acompanhamento ambulatorial, após tratamento oncológico e sem queixas de deglutição, realizaram avaliação funcional por meio da videofluoroscopia da deglutição. A classificação das imagens foi realizada por meio da escala de penetração-aspiração desenvolvida por Rosenbek. O teste do χ2 e a regressão logística foram aplicados para associação das categorias de idade aos desfechos (penetração e aspiração). Resultados: Os pacientes com idade acima de 60 anos apresentaram maior prevalência de penetração (24,29%) e aspiração (48,57%) do que aqueles com idade inferior a 60 anos. Nesta amostra, a aspiração se mostrou associada à idade. Pacientes acima de 60 anos tiveram chance 27% maior de penetração durante a deglutição do que os com menos de 60 anos. Pacientes acima de 60 anos tiveram chance aproximadamente quatro vezes maior de aspiração laringotraqueal do que pacientes com menos de 60 anos. Conclusão: Em pacientes sem queixas de deglutição no pós-operatório tardio de laringectomia supracricóidea, há maior chance de aspiração laringotraqueal em idosos acima de 60 anos do que em indivíduos abaixo de 60 anos.

OBJECTIVE: Describe differences in pretreatment symptoms and the composition of symptom clusters in older patients with oral and oropharyngeal cancer. METHODS: In this cross-sectional study, quality of life (QoL) assessments for cancer patients (EORCT QLQ-C30 and QLQ-H & N35) were applied to 161 cases of oral and oropharyngeal cancer at the time of enrollment in an outpatient clinic. They were used to evaluate QoL-related symptoms reported by patients, according to their occurrence. To identify symptom clusters, an exploratory factor analysis (EFA) was performed, and the relationships between these clusters and independent variables were assessed with linear regression models. RESULTS: The most prevalent symptoms were pain (52%), worry (48%), and weight loss (44%). Five factors were extracted from the EFA, of which 3 were noteworthy. The dysphagia cluster was common to both cancer sites, although more frequent in oropharyngeal cancer patients, and included symptoms such as difficulty swallowing, pain, and weight loss. The psychological cluster included symptoms related to feeling worried, nervous, and depressed. The asthenia cluster, in addition to being age-related, may represent the advanced stage or progression of the disease. CONCLUSION: The dysphagia cluster loaded the most symptoms and was common to both cancers. In addition to pain (one of the main symptoms of the dysphagia cluster), psychological symptoms were also important in both groups of patients. Adequate and early control of these symptom clusters at diagnosis could favor better management of symptoms during treatment.
OBJETIVO: Descrever diferenças nos sintomas pré-tratamento e na composição de clusters de sintomas em pacientes idosos com câncer oral e orofaríngeo. METODOLOGIA: Neste estudo seccional, avaliações de qualidade de vida (QV) para pacientes com câncer (EORCT QLQ-C30 e QLQ-H & N35) foram aplicadas a 161 casos incidentes de câncer oral e orofaríngeo no momento da inscrição no ambulatório. Essas avaliações foram utilizadas para analisar os sintomas relatados pelos pacientes quanto à QV, de acordo com a ocorrência. Para identificar agrupamentos de sintomas, uma análise fatorial exploratória (AFE) foi realizada, e a relação entre esses agrupamentos de sintomas e variáveis independentes foi avaliada com modelos de regressão linear. RESULTADOS: Os sintomas mais prevalentes foram dor (52%), preocupação (48%) e perda de peso (44%). Cinco fatores foram extraídos do AFE, três dignos de nota. Embora mais relatado por pacientes orofaríngeos, o agrupamento de disfagia foi comum a ambos os locais de câncer e incluiu sintomas como dificuldade para engolir, dor e perda de peso. O agrupamento psicológico incluiu sintomas relacionados a sentir-se preocupado, nervoso e deprimido. O agrupamento da astenia, além de relacionado à idade, pode representar o estágio avançado ou progressão da doença. CONCLUSÕES: O cluster de disfagia carregou a maioria dos sintomas e foi comum a ambos os tipos de câncer. Além da dor, que era um dos principais sintomas desse cluster, os sintomas psicológicos também foram importantes em ambos os grupos de pacientes. O controle adequado e precoce desses grupos de sintomas no diagnóstico pode favorecer o melhor manejo dos sintomas durante o tratamento.

Objective To describe functional and quality of life results after extended supratracheal laryngectomy. Methods In the period from September 2009 to January 2018, 11 male subjects were submitted to extended supratracheal laryngectomy. Swallowing abilities were assessed through videofluoroscopy and the clinical scale Functional Communication Measures of Swallowing. The voices were classified by means of the perceptual-auditory analysis Consensus Auditory-Perceptual Evaluation of Voice. All subjects completed a self-assessment questionnaire for voice and swallowing. Results Aspiration was found in four patients and all presented stasis in different structures. All subjects in this study were exclusively orally fed and hydrated. In the evaluation of quality of life in swallowing, patients had mean >80 in all areas (83.47 mean of scores). The general degree and the presence of roughness were the highest means present in Consensus Auditory-Perceptual Evaluation of Voice (37.81 and 49.36, respectively). The mean of 33.36 (±22.56) had little impact on quality of life under the perspective of vocal aspects. Conclusion After supratracheal laryngectomy, swallowing was sufficiently restored and the quality of life was satisfactory. The voice presents severely impaired quality and preserved oral communication, with low impact on the activities of daily living. All individuals who maintained two cricoarytenoid units presented better functional results in swallowing and voice.

RESUMO Objetivo Descrever os resultados funcionais e de qualidade de vida após a laringectomia supratraqueal alargada. Métodos No período de setembro de 2009 a janeiro de 2018, 11 indivíduos do sexo masculino foram submetidos à laringectomia supratraqueal alargada. As habilidades de deglutição foram avaliadas por meio da videofluoroscopia e da escala clínica Functional Communication Measures . As vozes foram classificadas por análise perceptivo-auditiva da Consensus Auditory-Perceptual Evaluation of Voice . Todos os voluntários preencheram um questionário de autoavaliação para voz e deglutição. Resultados A aspiração foi encontrada em quatro pacientes, e todos apresentaram estase em diferentes estruturas. Todos os sujeitos deste estudo apresentavam alimentação e hidratação exclusivas por via oral. Na avaliação da qualidade de vida na deglutição, os pacientes demonstraram médias >80 em todas as áreas (83,47 média dos escores). O grau geral e a presença de rugosidade foram os maiores escores médios na avaliação perceptivo-auditiva da voz (37,81 e 49,36 consecutivamente). A média de 33,36 (±22,56) demonstrou pouco impacto na qualidade de vida sob a perspectiva dos aspectos vocais. Conclusão Após a laringectomia supratraqueal, a deglutição foi suficientemente restaurada, e a qualidade de vida foi satisfatória. A voz apresenta qualidade gravemente comprometida com comunicação oral preservada, demonstrando baixo impacto nas atividades da vida diária. Todos os indivíduos que mantiveram duas unidades cricoaritenóideas apresentaram melhores resultados funcionais na deglutição e na voz.

Abstract Recurrent adnexal torsion is a rare gynecological emergency. We report a case of recurrent ipsilateral adnexal torsion in a woman with polycystic ovaries, previously submitted to a laparoscopic plication of the utero-ovarian ligament. Due to the recurrence after the plication of the utero-ovarian ligament, the authors performed a laparoscopic oophoropexy to the round ligament, which is an underreported procedure. The patient was asymptomatic for 1 year, after which she had a new recurrence and needed a unilateral laparoscopic adnexectomy. Since then, she regained the quality of life without any gynecological symptoms. Oophoropexy to the round ligament may be considered when other techniques fail or, perhaps, as a first option in selected cases of adnexal torsion, as it may allow the prevention of recurrence without increasing morbidity while preserving the adnexa.
Resumo A torção anexial recorrente é uma emergência ginecológica rara. Os autores descrevem um caso de torsão anexial unilateral recorrente em uma paciente com síndrome de ovário policístico, previamente submetida a plicatura do ligamento utero-ovárico por laparoscopia. Nesta circunstância, os autores decidiram realizar uma ooforopexia laparoscópica ao ligamento redondo, uma técnica pouco descrita na literatura. A paciente manteve-se assintomática durante 1 ano, período após o qual teve nova recorrência, tendo-se decidido realizar uma anexectomia laparoscópica unilateral. Desde então, ela recuperou a qualidade de vida sem qualquer sintoma ginecológico. A ooforopexia ao ligamento redondo é uma técnica que deverá ser considerada quando outras falham e, em casos selecionados de torsão anexial recorrente, poderá ser considerada a primeira abordagem, para prevenir a recorrência e preservar o anexo.

Recurrent adnexal torsion is a rare gynecological emergency. We report a case of recurrent ipsilateral adnexal torsion in a woman with polycystic ovaries, previously submitted to a laparoscopic plication of the utero-ovarian ligament. Due to the recurrence after the plication of the utero-ovarian ligament, the authors performed a laparoscopic oophoropexy to the round ligament, which is an underreported procedure. The patient was asymptomatic for 1 year, after which she had a new recurrence and needed a unilateral laparoscopic adnexectomy. Since then, she regained the quality of life without any gynecological symptoms.Oophoropexy to the round ligament may be considered when other techniques fail or, perhaps, as a first option in selected cases of adnexal torsion, as it may allow the prevention of recurrence without increasing morbidity while preserving the adnexa.
A torção anexial recorrente é uma emergência ginecológica rara. Os autores descrevem um caso de torsão anexial unilateral recorrente em uma paciente com síndrome de ovário policístico, previamente submetida a plicatura do ligamento utero-ovárico por laparoscopia. Nesta circunstância, os autores decidiram realizar uma ooforopexia laparoscópica ao ligamento redondo, uma técnica pouco descrita na literatura. A paciente manteve-se assintomática durante 1 ano, período após o qual teve nova recorrência, tendo-se decidido realizar uma anexectomia laparoscópica unilateral. Desde então, ela recuperou a qualidade de vida sem qualquer sintoma ginecológico.A ooforopexia ao ligamento redondo é uma técnica que deverá ser considerada quando outras falham e, em casos selecionados de torsão anexial recorrente, poderá ser considerada a primeira abordagem, para prevenir a recorrência e preservar o anexo.

BACKGROUND: Diabetes mellitus patients (DM) have more severe progression of atherosclerotic disease than non-diabetic (NDM) individuals. In situ inflammation and oxidative stress are key points in the pathophysiology of atherosclerosis, a concept largely based on animal model research. There are few studies comparing inflammation and oxidative stress parameters in medium-sized arteries between DM and NDM patients. A fragment of the internal mammary artery used in coronary artery bypass grafting (CABG) will be employed for this purpose OBJECTIVE: To assess the expression of inflammatory markers tumor necrosis factor-α, transforming growth factor-ß1, nuclear factor kappa B, the enzymes superoxide dismutase, and catalase in the vascular wall of the arterial graft used in CABG, comparing DM and NDM patients RESULTS: The present study will add information to the vascular degenerative processes occurring in diabetic patients.

Pancreatic metastases are rare; they account for only 2% of all pancreatic malignancies and usually occur when associated with a disseminated metastatic disease. Solitary pancreatic metastases are even less frequent, and there are few reports regarding surgical resection. We report the case of a 77-year-old female patient diagnosed with a single cephalo-pancreatic metastasis of renal cell carcinoma, 16 years after a total nephrectomy. The patient underwent successful pancreaticoduodenectomy, and the diagnosis was confirmed. A subsequent positron emission tomography (PET) scan showed disease relapse, and tyrosine kinase inhibitor treatment with sunitinib was initiated. After 1 year and 4 months, the PET-computed tomography scan showed a complete radiologic response.
