Resumo Objetivo Traçar o perfil sociodemográfico dos agentes de combate a endemias (ACEs) dos municípios que compõem a microrregional de saúde de Itaúna, Minas Gerais; e apreender a percepção dos profissionais da vigilância entomológica sobre a doença de Chagas e serviços de saúde. Metodologia Aplicou-se um questionário semiestruturado aos ACEs e foi realizado um grupo focal com os coordenadores de endemias e digitadores. Resultados Dentre os ACEs, a maioria era do sexo feminino, entre 21 e 40 anos, com ensino médio, possuindo contrato de trabalho temporário há menos de 5 anos. Foi possível apreender: as más condições de trabalho dos ACEs, destacando-se a alta rotatividade e defasagem salarial; ausência de ações de promoção à saúde relacionadas à doença de Chagas; desarticulação entre a Atenção Primária à Saúde (APS) e Vigilância à Saúde (VS); e críticas às ações de controle da doença pós-processo de descentralização da saúde. Conclusões Há urgência na concretização da legislação inerente à natureza trabalhista e às condições de trabalho dos ACEs, bem como ao planejamento conjunto das ações de APS e VS, garantindo a atenção integral por meio de ações de promoção à saúde voltadas à população, focando especialmente a doença de Chagas, consolidando o SUS.

Abstract Objective To trace the sociodemographic profile of endemic disease combat agents (ACEs) in the municipalities that make up the health microregion of Itaúna, Minas Gerais; and apprehend the perception of entomological surveillance professionals about Chagas disease and health services. Methodology A semi-structured questionnaire was applied to the ACEs and a focus group was held with coordinators of endemic diseases and typists. Results Among the ACEs, the majority were female, between 21 and 40 years old, with high school education, with a temporary work contract for less than 5 years. It was possible to apprehend: the poor working conditions of the ACEs, highlighting the high turnover and wage gap; absence of health promotion actions related to Chagas disease; disarticulation between Primary Health Care (PHC) and Health Surveillance (HS); and criticism of disease control actions after the health decentralization process. Conclusions There is an urgent need to implement the legislation inherent to the labor nature and working conditions of the ACEs, as well as the joint planning of PHC and SV actions, guaranteeing comprehensive care through health promotion actions aimed at the population, focusing especially on Chagas disease, consolidating the SUS.

American Cutaneous Leishmaniasis in Eastern Minas Gerais: veiled reality of a neglected disease / Leishmaniose Tegumentar Americana no Leste de Minas Gerais: realidade velada de uma doença negligenciada

Objective: to analyze the notified and confirmed cases of ACL in a municipality in east Minas Gerais, from 2007 to 2020. Methods: a combined study was carried out as a cross-sectional and an ecological approach of time series type, using notified and confirmed ACL cases, from 2007 to 2020. Primary and secondary data were used. Data were analyzed using descriptive and inferential statistics (simple linear regression, T-test, Mann-Whitney, chi-square (χ2) at a 5% significance level). Results: a total of 219 cases were reported with a decreasing temporal trend, with a higher frequency observed for the cutaneous form (82.6%), age group 40 to 59 years (32.1%), black race (56.4%), and completed elementary school (47.7%). Individuals with the mucosal clinical form had lesions for a longer time, a greater chance of not progressing to cure, and used more vials of meglumine antimoniate when compared to patients with the cutaneous form. Conclusions: different correlations were observed between the variables studied and the profile of involvement described in the scientific literature, with the clinical form predominantly cutaneous and with a good prognosis.

Latin American surgical outcomes study: study protocol for a multicentre international observational cohort study of patient outcomes after surgery in Latin American countries.

Background: Reported data suggest that 4.2 million deaths will occur within 30 days of surgery worldwide each year, half of which are in low- and middle-income countries. Postoperative complications are a leading cause of long-term morbidity and mortality. Patients who survive and leave the hospital after surgical complications regularly experience reductions in long-term survival and functional independence, resulting in increased costs. With a high volume of surgery performed, there is a growing perception of the substantial impact of even minor enhancements in perioperative care. The Latin American Surgical Outcomes Study (LASOS) is an international, multicentre, prospective cohort study of adults submitted to in-patient surgery in Latin America aiming to provide detailed data describing postoperative complications and surgical mortality. Methods: LASOS is a 7 day cohort study of adults undergoing surgery in Latin America. Details of preoperative risk factors, intraoperative care, and postoperative outcomes will be collected. The primary outcome will be in-hospital postoperative complications of any cause. Secondary outcomes include in-hospital all-cause mortality, duration of hospital stay after surgery, and admission to a critical care unit within 30 days after surgery during the index hospitalisation. Results: The LASOS results will be published in peer-reviewed journals, reported and presented at international meetings, and widely disseminated to patients and public in participating countries via mainstream and social media. Conclusions: The LASOS may augment our understanding of postoperative complications and surgial mortality in Latin America. Clinical trial registration: NCT05169164.

Uso de estatinas melhora a proteção cardiometabólica promovida pelo treinamento físico em ambiente aquático: Um ensaio clínico randomizado / Statin use improves cardiometabolic protection promoted by physical training in an aquatic environment: A Randomized Clinical Trial

Resumo Fundamento: O uso de estatinas destaca-se como a terapia mais frequentemente utilizada para o tratamento de dislipidemias e pode ser considerado a intervenção farmacológica mais eficiente para a redução da lipoproteína de baixa densidade (LDL). Por outro lado, o treinamento físico pode ser considerado uma estratégia não farmacológica eficiente e segura para promover melhorias no perfil lipídico. No entanto, não se sabe qual seria a influência das estatinas nas adaptações lipídicas decorrentes do treinamento aquático em populações com dislipidemia. Objetivos: Analisar a influência do uso de sinvastatina nas adaptações lipídicas decorrentes do treinamento aeróbico em meio aquático e de resistência em mulheres idosas com dislipidemia. Métodos: Sessenta e nove mulheres idosas (66,13 ± 5,13 anos), sedentárias e dislipidêmicas, tanto não usuárias quanto usuárias de sinvastatina (20 mg e 40 mg), foram randomizadas nos 3 grupos seguintes: treinamento aeróbico em meio aquático (WA), treinamento de força em meio aquático (WR) e grupo controle (GC). A duração total das intervenções, para todos os grupos experimentais, foi de 10 semanas, com 2 sessões semanais. As análises bioquímicas foram realizadas antes do início das intervenções e repetidas após o final do ensaio. Foram utilizadas equações de estimativa generalizada para comparar esses dados, estabelecendo α = 0,05. Resultados: Na análise por intenção de tratar, as participantes medicadas demonstraram uma redução de magnitude maior do colesterol total (CT) (−3,41 a −25,89 mg.dl−1; p = 0,038), LDL (−5,58 a −25,18 mg.dl−1; p = 0,007) e da relação CT/HDL (−0,37 a −0,61; p = 0,022) quando comparadas às participantes não medicadas, essa redução sendo estatisticamente significativa apenas no grupo WR. Conclusões: O uso de estatina incrementa as adaptações promovidas pelo treinamento físico aquático no CT, nos níveis de LDL e na relação CT/HDL, sendo mais pronunciado após WR.

Abstract Background: Statin use is highlighted as the most commonly utilized therapy for the treatment of dyslipidemias and can be considered as the most efficient pharmacological intervention for low-density lipoprotein (LDL) reduction. On the other hand, physical training can be considered an efficient and safe non-pharmacological strategy to promote improvements in lipid profile. However, the influence of statins on lipid adaptations arising from water-based training in populations with dyslipidemia is not known. Objectives: To analyze the influence of simvastatin use on lipid adaptations arising from water-based aerobics and resistance training in elderly women with dyslipidemia. Methods: Sixty-nine elderly (66.13 ± 5.13 years), sedentary, and dyslipidemic women, both non-users and users of simvastatin (20 mg and 40 mg), were randomized into the following 3 groups: water-based aerobic training (WA), water-based resistance training (WR), and control group (CG). Total duration of interventions, for all experimental groups consisted of 10 weeks, with 2 weekly sessions. Biochemical analyses were performed before the beginning of the interventions and repeated after the end of the trial. Generalized estimating equations were used to compare these data, setting α = 0.05. Results: In intention-to-treat analysis, the medicated participants obtained a greater magnitude of decrease in total cholesterol (TC) (−3.41 to −25.89 mg.dl−1; p = 0.038), LDL (−5.58 to −25.18 mg.dl−1; p = 0.007) and TC/HDL ratio (−0.37 to −0.61; p = 0.022) when compared to the non-medicated participants, and this decrease was statistically significant only in the WR group. Conclusions: Statin use enhances the adaptations promoted by water-based physical training in CT, LDL levels, and CT/HDL ratio, and it is more pronounced after WR.

Platelet Reactivity and Coagulation Markers in Patients with COVID-19.

INTRODUTION: COVID-19 is associated with an increased risk of thrombotic events. However, the contribution of platelet reactivity (PR) to the aetiology of the increased thrombotic risk associated with COVID-19 remains unclear. Our aim was to evaluate PR in stable patients diagnosed with COVID-19 and hospitalized with respiratory symptoms (mainly dyspnoea and dry cough), in comparison with a control group comprised of non-hospitalized healthy controls. METHODS: Observational, case control study that included patients with confirmed COVID-19 (COVID-19 group, n = 60) and healthy individuals matched by age and sex (control group, n = 60). Multiplate electrode aggregometry (MEA) tests were used to assess PR with adenosine diphosphate (MEA-ADP, low PR defined as < 53 AUC), arachidonic acid (MEA-ASPI, low PR < 86 AUC) and thrombin receptor-activating peptide 6 (MEA-TRAP, low PR < 97 AUC) in both groups. RESULTS: The rates of low PR with MEA-ADP were 27.5% in the COVID-19 group and 21.7% in the control group (OR = 1.60, p = 0.20); with MEA-ASPI, the rates were, respectively, 37.5% and 22.5% (OR = 3.67, p < 0.001); and with MEA-TRAP, the incidences were 48.5% and 18.8%, respectively (OR = 9.58, p < 0.001). Levels of D-dimer, fibrinogen, and plasminogen activator inhibitor 1 (PAI-1) were higher in the COVID-19 group in comparison with the control group (all p < 0.05). Thromboelastometry was utilized in a subgroup of patients and showed a hypercoagulable state in the COVID-19 group. CONCLUSION: Patients hospitalized with non-severe COVID-19 had lower PR compared to healthy controls, despite having higher levels of D-dimer, fibrinogen, and PAI-1, and hypercoagulability by thromboelastometry.

Residual neuromuscular blockade and late neuromuscular blockade at the post-anesthetic recovery unit: prospective cohort study.

INTRODUCTION AND OBJECTIVES: The use of neuromuscular blockers during surgery represented a landmark for anesthesiology. However, their use can prompt residual Neuromuscular Blockade (RNMB) and objective monitoring of neuromuscular function is crucial to warrant the recovery of muscle strength. The present study aimed to estimate the incidence of RNMB and late Neuromuscular Blockade (LNMB) at the Post-Anesthetic Recovery Unit (PACU). METHOD: The study included 85 patients, 43 of which received cisatracurium and 42 of which, rocuronium. The depth of the Neuromuscular Blockade (NMB) was assessed by Train Of Four (TOF). NMB reversal was performed with the administration of neostigmine and atropine.RNMB was defined when a patient presented TOF below 90% at the PACU. RESULTS: RNMB at the PACU was diagnosed in 39.5% and 40.5% of the patients receiving cisatracurium and rocuronium, respectively (p = 1.0). LNMB at the PACU was found in 32.6% and 16.7% of the patients receiving cisatracurium and rocuronium, respectively (p = 0.131). CONCLUSIONS: The incidence ofRNMB remains significant despite the use of intermediate-acting neuromuscular blockers and reversal agents. There was no statistically significant difference in the incidence of RNMB or LNMB in patients receiving cisatracurium or rocuronium. The use of objective NMB monitoring is effective for the diagnosis of RNMB, as well as for treatment management.

Acute moderate-intensity aerobic exercise promotes purinergic and inflammatory responses in sedentary, overweight and physically active subjects.

NEW FINDING: What is the central question of this study? How does moderate-intensity aerobic exercise affect the behaviour of purinergic enzymes in sedentary, overweight and physically active subjects? What is the relationship between purinergic and inflammatory responses triggered by exercise? What is the main finding and its importance? Moderate-intensity aerobic exercise modifies the activity of purinergic enzymes and the levels of nucleotides and nucleosides. These results are similar in subjects with different biological characteristics. 5'-Nucleotidase activity and adenosine levels are associated with inflammatory responses. This study suggests that a purinergic pathway is related to the inflammatory responses triggered by exercise. ABSTRACT: Purinergic signalling is a mechanism of extracellular communication that modulates events related to exercise, such as inflammation and coagulation. Herein, we evaluated the effects of acute moderate-intensity exercise on the activities of purinergic enzymes and plasma levels of adenine nucleotides in individuals with distinct metabolic characteristics. We analysed the relationship between purinergic parameters, inflammatory responses and cardiometabolic markers. Twenty-four healthy males were assigned to three groups: normal weight sedentary (n = 8), overweight sedentary (n = 8) and normal weight physically active (n = 8). The volunteers performed an acute session of moderate-intensity aerobic exercise on a treadmill at 70% of V̇O2peak ; blood samples were drawn at baseline, immediately post-exercise and at 1 h post-exercise. Immediately post-exercise, all subjects showed increases in ATP, ADP, AMP and p-nitrophenyl thymidine 5'-monophosphate hydrolysis, while AMP hydrolysis remained increased at 1 h after exercise. High-performance liquid chromatography analysis demonstrated lower levels of ATP and ADP at post- and 1 h post-exercise in all groups. Conversely, adenosine and inosine levels increased at post-exercise, but only adenosine remained augmented at 1 h after exercise in all groups. With regard to inflammatory responses, the exercise protocol increased tumour necrosis factor α (TNF-α) and interleukin 8 (IL-8) concentrations in all subjects, but only TNF-α remained elevated at 1 h after exercise. Significant correlations were found between the activity of 5'-nucleotidase, adenosine levels, V̇O2peak , triglyceride, TNF-α and IL-8 levels. Our findings suggest a purinergic signalling pathway that participates, at least partially, in the inflammatory responses triggered by acute moderate-intensity exercise. The response of soluble nucleotidases to acute moderate exercise appears to be similar between subjects of different biological profiles.

Adrenocortical carcinoma: Retrospective analysis of the last 22 years.

BACKGROUND: Adrenocortical carcinoma (ACC) is a rare disease with a poor prognosis. The clinical experience acquired, even from a small number of cases, has improved understanding of this condition. The purpose of this study is to characterize patients with ACC followed up at a Portuguese reference center over the past 22 years. METHODS: Retrospective analysis of clinical records of patients with histopathological diagnosis of ACC followed up from 1992 to 2014. RESULTS: The study sample consisted of 22 patients, 20 of them female. Eleven patients were in stage II, four in stage III, and five in stage IV; 13 patients had functioning lesions. Adrenalectomy was performed in 20 patients, with complete tumor resection in 90% of the cases. During follow-up, eight patients experienced recurrence of local disease, and 12 distant metastases. Fourteen patients received mitotane, 35.7% (n=5) as adjuvant therapy and 64.3% (n=9) after recurrence; therapeutic plasma mitotane levels were achieved in 70% of patients. Stage III patients who received adjuvant therapy had longer survival time (13.5 vs. 2.5 months). Two patients were given chemotherapy associated to mitotane. Median survival was 11 months (0-257 months); it was slightly longer in younger patients or patients with non-functioning tumors. Six patients are still alive, four of them with no evidence of disease. CONCLUSION: Despite the overall poor prognosis, some patients with ACC may have a long survival time. Although complete tumor removal remains the only potentially curative treatment, diagnosis at a younger age, presence of non-functioning tumors, and mitotane treatment also seemed to be associated to longer survival in our patients.

Tratamento do hiperesplenismo por embolizaçäo esplênica em uma paciente com câncer de ovário para possibilitar a administraçäo de quimioterapia antineoplásica / Treatment of hyperplenism in patient with ovarian cancer to allow chemotherapy

O hiperesplenismo é uma síndrome caracterizada por esplenomegalia que, por sua vez, produz um quadro de anemia, leucopenia, trombocitpenia ou qualquer combinaçäo destas citpenias no contexto de uma medula óssea normal ou hiperplásica. Estas citopenias, por definiçäo, se corrigem com a esplenectomia. o quadro de leucopenia, anemia e/ou trombocitopenia decorrentes do hiperesplenismo é especialmente preocupante em pacientes oncológicos. Nestes pacientes, o hiperesplenismo muitas vezes se constitui em um fator limitante à administraçäo de doses terapêuticas de drogas quimioterápicas mielotóxicas. Apresentamos aqui um caso de uma paciente de 61 anos com esplenomegalia à doença de Caroli e portadora de cistoadenocarcinoma seroso papilífero invasivo estádio III (FIGO), cuja quimioterapia foi complicada por pancitopenia prolongada. O mielograma revelou uma medula óssea hipercelular sem evidência de alteraçöes mielodisplásicas ou megaloblásticas compatível com a presença de hiperesplenismo. Com a condiçäo clínica precária desta paciente precluia a esplenectomia, procedeu-se à embolizaçäo parcial esplênica (EPE) que resultou em melhora importante e prolongada dos seus níveis hematimétricos. Pudemos, assim, administrar quimioterapia antineoplásica para esta paciente sem a ocorrência de mielosupressäo importante. Concluímos, portanto, que a embolizaçäo esplênica é uma alternativa para casos de pacientes com câncer e necessidade de quimioterapia e com pancitopenia intensificada pela presença de hiperesplenismo.
