ABSTRACT
BACKGROUND: The aim of this study was to describe the perception of dentists from the North macroregion of Minas Gerais, Brazil, users of telediagnosis in Oral Medicine, during the COVID-19 pandemic. MATERIAL AND METHODS: This is a cross-sectional and descriptive study. Data collection was carried out online, between May and October 2022. The information was transferred to the Statistical Package for the Social Sciences for Windows (SPPS)® version 24. RESULTS: The sample consisted of 255 dentists, predominantly female. Regarding perception, a significant percentage (47.8%) of respondents agreed that they would like to use telediagnosis frequently, more than half (60.6%) agreed that the technology is easy to use, only a small percentage (8.8%) needed technical support to use it and almost half (48.2%) mentioned the desire to continue using it after the pandemic. When asked if patients felt confident and comfortable when passing on information, more than half disagreed or remained neutral (58.4%), a similar result was found in relation to confidence in the application of the instrument by professionals. CONCLUSIONS: It is concluded that, during the pandemic, telediagnosis in Oral Medicine was an easy and adequate tool. However, professionals must be trained and prepared to be comfortable and ready for use.

OBJECTIVES: The objective of this study was to analyse the global burden of disease attributable to undernutrition and high body mass index (BMI) in Brazil and its 27 states, as well as its association with the socio-demographic index (SDI) from 1990 to 2019. STUDY DESIGN: This is an epidemiological time-series study. METHODS: This study analysed the undernutrition and high BMI estimated by the Global Burden of Disease study conducted from 1990 to 2019 for Brazil and its states, using the following metrics: absolute number of deaths, standardised mortality rate, and disability-adjusted life years (DALYs). This study also analysed the correlation between the percentage variation of mortality rates and SDI. RESULTS: A decrease in the number of deaths (-75 %), mortality rate (-75.1 %), and DALYS (-72 %) attributable to undernutrition was found in Brazil and in all regions. As regarding the high BMI, an increase in the number of deaths was found (139.6 %); however, the mortality rate (-9.7) and DALYs (-6.4 %) declined in all regions, except in the North and Northeast regions, which showed an increase. A strong correlation was identified between undernutrition and high BMI with SDI. CONCLUSION: Our study observed a double burden of malnutrition in Brazil, with a reduction in the burden of diseases due to malnutrition in Brazil and variation in the burden due to high BMI according to the socioeconomic status of the region. Public policies are necessary in order to guarantee the human right to a healthy and sustainable diet, together with food and nutrition security and a diminishing of social inequality.

PURPOSE OF REVIEW: This review summarizes the literature about the transition from psoriasis to psoriatic arthritis (PsA), focusing on musculoskeletal ultrasound (MSUS) for detecting subclinical inflammation and its role in diagnosis and triage of high-risk patients. RECENT FINDINGS: MSUS effectively detects subclinical musculoskeletal inflammation in patients with psoriasis; however, some of these lesions are non-specific and can be found in healthy individuals. Preliminary evidence suggest that subclinical sonographic findings may predict progression to PsA in psoriasis patients. MSUS can also improve referrals' accuracy and its integration in the PsA classification criteria may improve early PsA detection. MSUS is a valuable tool for detecting subclinical abnormalities in psoriasis patients, which indicate an increased likelihood of progressing to PsA. Its integration into referral protocols and clinical use could improve PsA diagnosis. We propose an MSUS-inclusive algorithm for PsA referrals and triage, which requires validation. The potential of early intervention in reducing PsA progression in psoriasis patients with subclinical inflammation remains to be established.

OBJECTIVES: The aim of this study was to analyse the trends of avoidable mortality in Brazil from 1990 to 2019 and its correlation with sociodemographic indexes (SDIs). STUDY DESIGN: Epidemiological mortality trends. METHODS: This study analysed data from the Global Burden of Disease database. The list of causes of avoidable death, as proposed by Nolte and McKee, was applied and included 32 causes. The current study used age-standardised mortality rates and the rates of change, in addition to a correlation analysis between avoidable death and the SDI. RESULTS: Mortality rates decreased from 343.90/100,000 inhabitants in 1990 to 155.80/100,000 inhabitants in 2019. Infectious diseases showed the largest decline in mortality rates, but notable decreases were also found for diarrhoeal diseases (-94.9%), maternal conditions (-66.5%) and neonatal conditions (-60.5%). Mortality rates for non-communicable diseases (NCDs) also decreased (-48%) but maintained a similar absolute number of deaths in 2019 compared with 1990. Decreased mortality rates were also found for ischaemic heart disease (-49.1%), stroke (-61.4%) and deaths due to adverse effects caused by medical treatments (-26.2%). Avoidable mortality rates declined in all of the 27 Brazilian states, and a high correlation was found between deaths and SDI (R = -0.74; P < 0.000001). CONCLUSIONS: A reduction in avoidable deaths was found throughout Brazil over the study period, although major regional inequalities were revealed. Richer states presented the best overall reduction in mortality rates. The biggest decreases in mortality were seen in maternal and paediatric infectious diseases in the poorest states due to the expansion of the Primary Health System and improvements in sanitation. Today, NCDs predominate and efforts should be made to formulate public policies for the prevention and control of NCDs.

OBJECTIVES: To analyse spatial-temporal changes and spatial association of homicide rates with violence, sociodemographic, public security and human rights indicators in Brazilian municipalities. STUDY DESIGN: An ecological study using homicide estimates from the Global Burden of Disease and population from the Brazilian Ministry of Health, 2000 to 2018. The explanatory variables come from the systems of mortality, notifications of violence and security, and the Brazilian Institute of Geography and Statistics. METHODS: Moran indices and maps identified clusters of high and low risk for homicides in three trienniums (p < 0.05). Multivariate linear and spatial regressions estimated explanatory factors' contributions for the last triennium. RESULTS: Municipalities with high rates of homicides (>34/100,000) doubled, reaching 21.5 %. Those rates were concentrated in big cities, and increased in smaller municipalities. Increases in critical areas were found in the Northeast and North regions: more than 40 % in the states of Sergipe, Bahia, Ceará, Rio Grande do Norte and Roraima. Decreases occurred in the Southeast and Midwest regions: more than 35 % in São Paulo and Rio de Janeiro states. The spatial model, with an 18.9 % higher R2 (0.706), showed a positive association for records of violence, Blacks, low-level education, municipalities >50,000 inhabitants and municipalities with homicide and municipal police. CONCLUSIONS: An increase in and the interiorisation of homicide risk areas in Brazil was observed, with displacement among regions (from the Southeast to the North/Northeast). The level of violence was the main explanatory factor for homicides. Territorial space proved to be important to understand and prevent lethal crime.

OBJECTIVES: The objective of this study was to identify Brazil's most critical garbage codes (GCs) reclassified to Chagas disease (ChD) in mortality data and their proportions. We also estimated the potential impact of misclassification on the number of deaths attributed to ChD. STUDY DESIGN: Population-based descriptive study. METHODS: We used the Mortality Information System (SIM; in Portuguese) data before and after routine GC investigation in 2015-2019 to evaluate ChD deaths detected among them. We identified priority GCs, which contributed more than 0.1 % to the percentage of total ChD deaths registered. Spearman's correlation was used to evaluate the association between the reclassification of priority GCs and ChD prevalence. Then, we applied the GC correction factors to estimate the number of deaths attributed to ChD. RESULTS: 22,154 deaths were reported as ChD in the study period. Among them, 1004 deaths originally listed as priority GCs were deaths reclassified to ChD after an investigation in the SIM final database. Unspecific cardiomyopathy (10.2 %), unspecific heart diseases (4.7 %), and heart failure (2.8 %) were GCs with the highest proportions of reclassification to ChD in Brazil. Higher ChD prevalence at the state level was associated with a higher proportion of GC deaths reclassified as ChD. When applying correction factors identified after investigation, we estimated an increase of 26.4 % in registered ChD deaths, mostly in states with higher endemicity. CONCLUSIONS: GCs might conceal deaths due to ChD, particularly in Brazil's states with higher endemicity. The approach suggested in this study may offer an alternative method for estimating ChD-related deaths in endemic countries.

The association between subclinical thyroid dysfunctions and autonomic modulation changes has been described by many studies with conflicting results. We aimed to analyze the association between subclinical hyperthyroidism (SCHyper), subclinical hypothyroidism (SCHypo), and heart rate variability (HRV) using the baseline from ELSA-Brasil. SCHyper and SCHypo were classified by use of medication to treat thyroid disorders, thyrotropin levels respectively above and under the reference range, and normal free thyroxine levels. For HRV, the participants underwent 10 min in supine position and the R-R intervals of the final 5 min were selected for analysis. We first used linear regression models to report crude data and then, multivariate adjustment for sociodemographic (age, sex, and race) and cardiovascular risk factors (hypertension, dyslipidemia, diabetes, smoking, body mass index, use of alcohol, and leisure physical activity) using the euthyroid group as reference. From 9270 subjects (median age, 50; interquartile range: 44-56), 8623 (93.0%) were classified as euthyroid, 136 (1.5%) as SCHyper, and 511 (5.5%) as SCHypo. Compared to euthyroid subjects, SCHyper participants presented significantly higher heart rate (68.8 vs 66.5 for euthyroidism, P=0.007) and shorter R-R intervals (871.4 vs 901.6, P=0.007). Although SCHyper was associated with lower standard deviation of NN interval (SDNN) (β: -0.070; 95% confidence interval (95%CI): -0.014 to -0.009) and low-frequency (LF) (β: -0.242, 95%CI: -0.426 to -0.058) compared to the euthyroid group, these differences lost significance after multivariate adjustment for confounders. No significant differences were found for HRV in SCHypo. No association was found between HRV and SCHyper or SCHypo compared to euthyroid subjects in this sample of apparently healthy subjects.

This study reports the occurrence of Pachycrepoideus vindemmiae (Rondani) (Hymenoptera: Pteromalidae) and Spalangia cameroni Perkins (Hymenoptera: Pteromalidae) as parasitoids of Ornidia obesa Fabricius (Diptera: Syrphidae) in poultry farms in Morrinhos, Goiás, state Brazil. Samples of chicken feces were collected at two weeks intervals and taken to the laboratory. The pupae were extracted by water flotation. Each pupa was placed in capsules of gelatin until the emergence of dipterous or their parasitoids. The parasitism percentage of P. vindemmiae and S. cameroni was 5.1 percent.
ABSTRACT
Endothelial function (EF) plays an important role in the onset and clinical course of atherosclerosis, although its relationship with the presence and extent of coronary artery disease (CAD) has not been well defined. We evaluated EF and the ST segment response to an exercise test in patients with a broad spectrum of CAD defined by coronary angiography. Sixty-two patients submitted to diagnostic catheterization for the evaluation of chest pain or ischemia in a provocative test were divided into three groups according to the presence and severity of atherosclerotic lesions (AL): group 1: normal coronaries (N = 19); group 2: CAD with AL <70 percent (N = 17); group 3: CAD with AL ¡Ý70 percent (N = 26). EF was evaluated by the percentage of flow-mediated dilatation ( percentFMD) in the brachial artery during reactive hyperemia induced by occlusion of the forearm with a pneumatic cuff for 5 min. Fifty-four patients were subjected to an exercise test. Gender and age were not significantly correlated with percentFMD. EF was markedly reduced in both groups with CAD (76.5 and 73.1 percent vs 31.6 percent in group 1) and a higher frequency of ischemic alterations in the ST segment (70.8 percent) was observed in the group with obstructive CAD with AL ¡Ý70 percent during the exercise test. Endothelial dysfunction was observed in patients with CAD, irrespective of the severity of injury. A significantly higher frequency of ischemic alterations in the ST segment was observed in the group with obstructive CAD. EF and exercise ECG differed among the three groups and may provide complementary information for the assessment of CAD.

INTRODUÇÃO: Os crescentes avanços tecnológicos desenvolvidos para o tratamento de distúrbios de condução cardíaca vêm proporcionando aos pacientes melhores condições de vida. As escalas de classificação funcional e questionários de qualidade de vida (QV) constituem uma forma suplementar de avaliação dos aspectos físicos, emocionais e funcionais dos pacientes. Entretanto, permanece a seguinte questão: existe correlação entre a classe funcional (CF) e a percepção da QV em usuários de marcapasso (MP)? OBJETIVO: O objetivo do estudo foi avaliar se existe correlação entre classe funcional (CF) e QV em portadores de MP cardíaco definitivo. MÉTODOS: Foram avaliados 14 usuários de MP. Para avaliar CF, foi utilizada a escala de atividade específica proposta por Goldman, e, com objetivo de avaliação da QV, foi aplicado o questionário Aquarel associado ao SF-36. Com o objetivo de verificar se existe correlação entre as variáveis, foi aplicado o teste de correlação de Spearman, considerando como significativo a< 0,05. Para a análise dos dados, foi utilizado Software SPSS for Windows versão 10.0. RESULTADOS: A CF correlacionou-se inversa e significativamente com a QV avaliada pelo Aquarel em seus três domínios: desconforto no peito (r= -0,666; p= 0,009); dispnéia (r= -0,604; p= 0,022) e arritmia (r= -0,550; p= 0,041). Já em relação ao SF-36, dos seus oito domínios, três estabeleceram uma correlação significativa com a CF: capacidade funcional (r= -0,745; p= 0,002); dor (r= -0,667; p= 0,009) e vitalidade (r= -0,591; p= 0,026). CONCLUSÃO: No presente estudo, encontrou-se correlação significativa entre CF e QV, sugerindo que as escalas de classificação funcional podem refletir aspectos da QV de portadores de MP.
INTRODUCTION: Growing technological progress in treating patients with heart conduction disturbances has provided such patients with better life conditions. Functional classification (FC) scales and quality of life (QOL) questionnaires are additional means for evaluating patients' physical, emotional and functional characteristics. However, the question remains as to whether there is any association between FC and perception of QOL among pacemaker users. OBJECTIVE: To evaluate whether there is any correlation between FC and QOL among definitive cardiac pacemaker users. METHOD: Fourteen pacemaker users were evaluated. To assess FC, the specific activity scale proposed by Goldman was used. To evaluate QOL, the Aquarel questionnaire was used in association with SF-36. The Spearman correlation test was applied to investigate whether there was any association between the variables, considering p< 0.05 to be significant. The SPSS for Windows software, version 10.0, was used for the data analysis. RESULTS: There was a significant negative correlation between FC and QOL through evaluation by Aquarel questionnaire in its three domains: chest discomfort (r= -0.666; p= 0.009); dyspnea (r= -0.604; p= 0.022); and arrhythmia (r= -0.550; p= 0.041). Among the eight domains of SF-36, three showed a significant correlation with FC: physical functioning (r= -0.745; p= 0.002); pain (r= -0.667; p= 0.009); and vitality (r= -0.591; p= 0.026). CONCLUSION: In the present study, a significant correlation was found between FC and QOL, thus suggesting that functional classification scales may reflect aspects of QOL among pacemaker users.

The pentavalent antimonial (Sb5+) meglumine is the drug of choice for the treatment of cutaneous leishmaniasis (CL) in Brazil. Although the cardiotoxicity of high-dose, long-term Sb5+ therapy is well known, the use of low-dose, short-term meglumine has been considered to be safe and relatively free from significant cardiac effects. In order to investigate the cardiotoxicity of low-dose, short-term therapy with meglumine in cutaneous leishmaniasis, 62 CL patients treated with meglumine were studied. A standard ECG was obtained before and immediately after the first cycle of treatment (15 mg Sb5+ kg-1 day-1). The electrocardiographic interpretation was carried out blindly by two investigators using the Minnesota Code. There were no significant differences in qualitative ECG variables before and after meglumine treatment. However, the corrected QT interval was clearly prolonged after antimonial therapy (420.0 vs 429.3 ms, P<10-6). QTc augmentation exceeded 40 ms in 12 patients, 7 of whom developed marked QTc interval enlargement (500 ms) after meglumine therapy. This previously unrecognized cardiac toxicity induced by short-term, low-dose antimonial therapy has potentially important clinical implications. Since sudden death has been related to QTc prolongation over 500 ms induced by high-dose antimonial therapy, routine electrocardiographic monitoring is probably indicated even in CL patients treated with short-term, low-dose meglumine schedules. Until further studies are conducted to establish the interactions between pentavalent antimonials and other drugs, special care is recommended when using meglumine in combination with other medications, in particular with drugs that also increase the QTc interval

A forma indeterminada da doença de Chagas é definida pela presença de infecção pelo Trypanosoma cruzi na ausência de manifestações clínicas, radiológicas e eletrocardiográficas de acometimento cardíaco ou digestivo. Pacientes na forma indeterminada podem apresentar anormalidades cardiovasculares significativas à propedêutica mais avançada. Entretanto, a validade do conceito de forma indeterminada tem sido reafirmada, pela simplicidade diagnóstica e benignidade do prognóstico. Na prática clínica, dificuldades diagnósticas são freqüentes, relacionadas à subjetividade e ao significado incerto de achados clínicos, eletrocardiográficos e radiológicos. Adicionalmente, o prognóstico na forma indeterminada não é uniformemente bom: após cinco a 10 anos, postula-se que um terço dos pacientes evoluirão para a forma cardíaca. A morte súbita, uma complicação rara, pode ser a primeira manifestação da doença. É necessária uma reavaliação do conceito de forma indeterminada, com redefinição dos critérios diagnósticos e da conduta terapêutica. A estratificação do risco individual, através de métodos clínicos e não-invasivos, pode permitir o reconhecimento de grupos de risco aumentado, passíveis de intervenções terapêuticas. Como o tratamento etiológico pode prevenir o aparecimento da cardiopatia, seu papel no manejo da forma indeterminada deve ser reavaliado.
The indeterminate form of Chagas' disease is defined by the absence of clinical, radiological and electrocardiographic manifestations of cardiac or digestive involvement in Trypanosoma cruzi chronic infected persons. When submitted to advanced cardiovascular tests, these patients may present significant abnormalities. However, the indeterminate form concept was reaffirmed as valid, since diagnostic criteria are simple and prognosis is benignant. In clinical practice, diagnostic difficulties are frequent, related to subjectivity and uncertain meaning of clinical, electrocardiographic and radiological findings. Moreover, indeterminate form prognosis is not equally good: after five to 10 years, a third of patients will have cardiopathy. Sudden death, a rare complication, may be the first manifestation of Chagas' disease. It is necessary to reappraise indeterminate form concept, redefining diagnostic criteria and therapeutic management. Clinical and noninvasive evaluation may allow individual risk stratification; therapeutic interventions may be beneficial in high risk groups. Since etiologic treatment may prevent cardiopathy, its role in indeterminate form management must be reassessed.
