The Relationship between Anxiety Symptoms and Perceived Quality of Life among Caregivers of Children with Autism Spectrum Disorder in the Amazon.

The relationship between anxiety symptoms and perceived quality of life among caregivers of children with autism was verified. To assess perceived quality of life, the Short Form Healthy Survey Item was used; perception of anxiety symptoms was assessed using the Beck Anxiety Inventory. Eighty caregivers of children with autism participated, with 68.7% of caregivers being mothers. Of the total number of caregivers, 68.8% had a severe level of anxiety. Regarding perceived quality of life, they demonstrated greater impairment in limitation due to physical aspects, limitation due to emotional aspects, vitality, and pain. Caregivers with severe anxiety levels had a worse quality of life in the domains of pain (p = 0.012), social aspects (p < 0.001), limitation due to emotional aspects (p = 0.001), and mental health (p < 0.001). However, in the functional capacity domain, caregivers with a moderate level of anxiety had a better physical capacity score (p = 0.001). There was a negative correlation between the general anxiety score and the general physical (p = 0.029) and general emotional components of perceived quality of life (p < 0.001). It was found that caregivers of children with ASD have a high level of anxiety, which is a predictor of the perception of a worse quality of life.

Emotional Eating and Uncontrolled Eating as Risk Predictors for Disordered Eating Attitudes in Candidates for Bariatric Surgery Treated at a Public Hospital in the Amazon.

This study analyzes the eating behavior and factors associated with the presence of disordered eating attitudes in patients undergoing bariatric surgery. It is a cross-sectional, descriptive, and analytical study conducted at a hospital in the Amazon region of Brazil. The Disordered Eating Attitude Scale reduced version (DEAS-s) was used to assess the risk of eating disorders and the Three-Factor Eating Questionnaire (TFEQ-R21) was used to characterize eating behavior. A total of 205 patients participated, with a mean age of 37.5 ± 8.6 years. The majority of participants were female (93.7%; p < 0.001), and the mean BMI was 45.3 ± 6.7 kg/m2. It was found that cognitive restraint had the highest mean (52.6 ± 19.9; p < 0.001). As for the DEAS-s, the question with the highest mean response was "spending one or more days without eating or consuming only liquids to lose weight" (2.80 ± 1.99). Female participants had a higher score for emotional eating (p = 0.016). Disordered eating attitudes showed a correlation with emotional eating and uncontrolled eating. These results suggest that candidates for bariatric surgery may have susceptibility to eating disorders. The importance of a multidisciplinary team conducting monitoring during the preoperative period is highlighted.

Relationship between Determinants of Food Choices and Socioeconomic and Demographic Factors of Individuals with Hepatitis B and C in the Amazon Region.

Knowing the determinants of food choices allows the nutritionist to develop more assertive guidelines considering biopsychosocial factors to produce effective changes in eating practices. This cross-sectional, descriptive, and analytical study aimed to test the correlation between the determinants of food choices and the socioeconomic and demographic factors of individuals with hepatitis B and C. Patients with hepatitis B and/or C aged between 20 and 74 years were evaluated from August 2020 to August 2021. Their socioeconomic and demographic data and clinical data were collected, and The Eating Motivation Survey (TEMS) was applied. A total of 145 individuals were evaluated, with a mean age of 53.54 ± 12.14 years. There were positive weak correlations between gender (p2 = 0.193; p = 0.020) and age (p2 = 0.177; p = 0.033) with the scale "preference"; negative correlations between age and the scales "price" (p2 = -0.204; p = 0.014) and "emotion control" (p2 = -0.168; p = 0.044); negative correlations between education and the scales "convenience" (p2 = -0.172; p = 0.039) and "social norms" (p2 = -0.206; p = 0.013); and income showed a negative correlation with "price" (p2 = -0.208; p = 0.012) and a positive correlation with "weight control" (p2 = 0.186; p = 0.025). These findings contribute to the development of more realistic and feasible eating strategies that favor food autonomy.

Adherence to Online Nutritional Monitoring Was Associated with Better Food Habits in People with T1DM during the COVID-19 Pandemic in Brazil.

Until this moment, no research has been found that has assessed adherence to online nutritional monitoring by adults with Diabetes Mellitus Type 1 (T1DM) during the pandemic. This article aims to analyze the association between eating habits and adherence to nutritional online care by adults with T1DM during social distancing because of the COVID-19 pandemic in Brazil. A cross-sectional study was carried out in July 2020. An online form was used to collect sociodemographic data, financial status, eating habits, carrying out online nutritional monitoring, and adherence to social distancing. Pearson's chi-squared test was performed with adjusted residual analysis and binomial logistic regression analysis (p < 0.05). Out of the 472 adults, only 8.9% had consulted with a nutritionist. Doing nutritional monitoring online during social distancing was associated with a reduction in the consumption of ultra-processed foods (p = 0.021), eating more servings of fruit (p = 0.036), and doing carbohydrate counting (CC) more frequently (p = 0.000). Doing nutritional monitoring online increased adherence to carbohydrate counting by 2.57 times and increased the consumption of fruits by 0.423 times. Therefore, nutritional monitoring, even if performed remotely, can influence the acquisition and maintenance of healthier eating habits, in addition to assisting adherence to the practice of CC.

Factors associated with grazing behavior in candidates for bariatric surgery at a hospital in the Amazon.

Blackground: To assess grazing behavior and associated factors in candidates for bariatric surgery monitored at a public hospital that is a reference in the care of people with severe obesity. Methods: Cross-sectional analytical study, with candidates for bariatric surgery of both genders, treated in a public hospital in the Amazon. To assess grazing behavior, the Repetitive Eating Questionnaire was used, and to investigate patterns of eating behavior, the Three Factor Eating Questionnaire was used, which assesses: Emotional Eating, Cognitive Restriction and Uncontrolled Eating. Sociodemographic information was obtained through self-report and the description of medication use through the medical record. Body mass index (BMI) was also calculated by measuring weight and height. The SPSS program, v. 21.0 was used. The study was approved by the Research Ethics Committee. Results: A total of 205 participants were evaluated, with a mean age of 37.5 ± 8.6 years, the majority (93.7%) being women and the majority (59.5%) was not also using medication to lose weight. About 66.3% of the participants had compulsive grazing. The factor with the highest score was cognitive restriction (p < 0.001). Individuals who used weight loss drugs had higher scores in the cognitive restriction factor (p = 0.015) and lower scores for uncontrolled eating (p = 0.008), compulsive grazing (p = 0.021) and non-compulsive grazing (p = 0.034). Conclusion: Linear regression showed that emotional eating and uncontrolled eating were predictors of both compulsive grazing and non-compulsive grazing behavior. It was observed that grazing behavior, cognitive restriction, emotional eating and uncontrolled eating are present and correlated in the studied patients. In addition, the use of weight loss drugs seems to help reduce dysfunctional eating behaviors in patients with severe obesity.

Relationship between Eating Behavior, Quality of Life and Weight Regain in Women after Bariatric Surgery.

Individuals undergoing bariatric Surgery (BS) may have long-term weight regain. There is a need to investigate factors that may be related to this and if they can interfere with Quality of Life (QOL). This study aims to evaluate the relationship between eating behavior, perception of QOL, and weight regain in women after 24 months of bariatric surgery. This was a transversal study with 50 adult women residents in the city of Belém, Brazil. Sociodemographic, anthropometric, eating behavior (Three-Factor Eating Questionnaire­TFEQ-21) and perception of QOL (Item Short Form Healthy Survey­SF-36) data were collected. In 60% (n = 30) there was weight regain (≥15%), with a mean weight regain of 23.3% (±18.4). Emotional eating was the most frequent pattern (p = 0.047). Regarding QOL, the functional capacity and limitation due to physical aspects domains had a better perception (p < 0.0001). Women without weight regain showed a better perception of the functional capacity aspects (p = 0.007), limitation due to physical aspects (p = 0.044), social aspects (p = 0.048), and general physical components (p = 0.016) and also had an inverse association with the perception of QOL in physical components (p = 0.008). Patterns of eating behavior and weight regain can damage the perception of QOL, especially physical capacity. Long-term follow-up is essential to evaluate the behavior of people who have undergone BS in order to prevent weight regain and QOL damage.

Adherence to Carbohydrate Counting Improved Diet Quality of Adults with Type 1 Diabetes Mellitus during Social Distancing Due to COVID-19.

To control glycemic variability in people with Type 1 diabetes mellitus (T1DM), it is essential to perform carbohydrate counting (CC), a strategy that ensures better quality of life for these patients. Thus, this study aims to analyze potential factors associated with adherence to CC in adults with T1DM during social distancing due to COVID-19 in Brazil. This was a single cross-sectional study carried out in July 2020. An online form was used to collect sociodemographic and economic data on the purchasing of supplies and food, as well as social distancing. The Chi-square test was performed with adjusted residuals analysis and a binomial logistic regression analysis (p < 0.05). Of 472 adults, 37.71% reported performing CC in the same frequency as before social distancing. There was an association between performance of CC and the type of city (p = 0.027), family income (p = 0.000), use of financial emergency aid (p = 0.045), type of insulin administration and glycemic monitoring (p < 0.000), and cooking more (p = 0.012). Participants who maintained or reduced consumption of ultra-processed foods were 0.62 times more likely to adhere to CC (OR 0.626, 95% IC: 0.419−0.935) and participants who cooked more were 1.67 times more likely to adhere to CC (OR 1.67, 95% CI: 1.146−2.447). There are still people with T1DM who did not know about and did not use CC method, which highlights the need for diabetes education.

Correlation between Anxiety Symptoms and Perception of Quality of Life in Women with More Than 24 Months after Undergoing Bariatric Surgery.

Purpose: To analyze the correlation between anxiety symptoms and perceived quality of life in women more than 24 months after undergoing bariatric surgery. Methods: Cross-sectional, descriptive and analytical study, carried out with women who underwent bariatric surgery after at least 24 months. To assess the level of anxiety symptoms, the Beck Inventory was used and to assess the perception of quality of life, the Item Short Form Healthy Survey was applied. Results: Of the 50 participants, 36.0% had reports indicative of moderate symptoms and 64.0% had severe symptoms of anxiety. The domains of quality of life that correlated with better perception were pain (p < 0.001), functional capacity (p = 0.013), general health status (p = 0.018), social aspects (p < 0.001), and mental health (p < 0.001). In linear regression, a significant inverse correlation was found between the general emotional component of quality of life and anxiety score (ß = −0.546; CI −1.419; −0.559; p < 0.001) and between the general physical component of quality of life and anxiety score (ß = −0.339; CI −0.899; −0.131; p = 0.010), both independent of weight regain and surgery time. Conclusions: It was observed that moderate to severe anxiety symptoms seem to interfere with the perception of quality of life, regardless of weight regain and surgery time.

Hepatitis C virus eradication on glycemic control and insulin resistance.

OBJECTIVE: To review data regarding the effects of hepatitis C virus eradication on glycemic control and insulin resistance. METHODS: This is an integrative literature review, carried out in the PubMed, SciELO, and Lilacs databases. Studies published in the past five years that were fully available, written in English or Portuguese, and have addressed the effects of eradication of the hepatitis C virus on glycemic control and insulin resistance were selected. RESULTS: Nine studies were selected. Among the results found, it was observed that there is no consensus on the effects of viral eradication on glycemic control and IR, as some authors show an eventual improvement in insulin resistance and glycemic control, while other studies indicate that there are no significant differences between the parameters evaluated after viral eradication. CONCLUSIONS: Although there is a relationship between hepatitis C virus infection and the development of insulin resistance and type 2 diabetes mellitus and recent advances in research, it was observed that there is no consensus on improving insulin resistance and glycemic control after antiviral treatment, probably due to methodological differences between studies. However, it emphasizes the need to guide people diagnosed with hepatitis C, regarding changes in lifestyle, encouragement of multidisciplinary monitoring, and control of other risk factors.

Behavioral Influence of Known Prognostic Markers on the Cardiologist's Decision following Acute Coronary Syndrome: the GRACE Score Paradox.

BACKGROUND: Behavioral scientists consistently point out that knowledge does not influence decisions as expected. GRACE Score is a well validated risk model for predicting death of patients with acute coronary syndromes (ACS). However, whether prognostic assessment by this Score modulates medical decision is not known. OBJECTIVE: To test the hypothesis that the use of a validated risk score rationalizes the choice of invasive strategies for higher risk patients with non-ST-elevation ACS. METHODS: ACS patients were consecutively included in this prospective registry. GRACE Score was routinely used by cardiologists as the prognostic risk model. An invasive strategy was defined as an immediate decision of the coronary angiography, which in the selective strategy was only indicated in case of positive non-invasive test or unstable course. Firstly, we evaluated the association between GRACE and invasiviness; secondly, in order to find out the actual determinants of the invasive strategy, we built a propensity model for invasive decision. For this analysis, a p-value < 0.05 was considered as significant. RESULTS: In a sample of 570 patients, an invasive strategy was adopted for 394 (69%). GRACE Score was 118 ± 38 for the invasive group, similar to 116 ± 38 for the selective group (p = 0.64). A propensity score for the invasive strategy was derived from logistic regression: positive troponin and ST-deviation (positive associations) and hemoglobin (negative association). This score predicted an invasive strategy with c-statistics of 0.68 (95%CI: 0.63-0.73), opposed to GRACE Score (AUC 0.51; 95%CI: 0.47-0.57). CONCLUSION: The dissociation between GRACE Score and invasive decision in ACS suggests that the knowledge of prognostic probabilities might not determine medical decision.

O nível de ansiedade, a renda e o acompanhamento psicológico podem influenciar na recorrência de peso corporal em mulheres submetidas a cirurgia bariátrica / Anxiety level, income and psychological monitoring can influence the recurrence of body weight in women submitted to bariatric surgery

Introdução: A melhora nos sintomas de ansiedade após a cirurgia bariátrica pode não permanecer estável em longo prazo, favorecendo a adoção de comportamentos alimentares disfuncionais. Objetivo: Testar a correlação entre o nível de ansiedade e a recorrência de peso em mulheres no pós-operatório tardio de cirurgia bariátrica e metabólica. Métodos: Foram avaliadas 50 mulheres adultas com no mínimo 24 meses após a cirurgia bariátrica e metabólica. Foram coletados dados sociodemográficos (idade, renda e nível de escolaridade) e de acompanhamento psicológico. Foram aferidos dados antropométricos (peso e altura). Para avaliar o nível de sintomas de ansiedade, foi utilizado o Inventário de Beck. Resultados: Foi encontrada média de idade de 40,9±11,4 anos. Todas apresentavam sintomas de ansiedade moderados a graves. Aquelas que estavam sem acompanhamento psicológico apresentavam maior peso corporal (p=0,049) e maior recorrência de peso (p=0,040). Observou-se correlação positiva entre o escore de ansiedade e a recorrência de peso, e correlação negativa entre o escore de ansiedade e a renda familiar. No modelo de regressão linear, a correlação entre o escore de ansiedade com a recorrência de peso (B=0,276; IC 0,003;0,594; p=0,048) e a renda (B=-0,310; IC -0,004;0,000; p=0,027) permaneceu significativa. Contudo, ao adicionar a variável "tempo de cirurgia", observou-se perda de significância entre ansiedade e recorrência de peso (B=0,270; IC -0,040; -0,624; p=0,083), mas manteve-se a correlação com a renda (B=-0,310; IC -0,004;-0,000; p=0,029). Conclusões: Ressalta-se a importância de suporte financeiro no pós-operatório, pelos custos com o tratamento, além de manter o acompanhamento com a equipe multiprofissional em longo prazo.

Introduction: The improvement in anxiety symptoms after bariatric surgery may not remain stable in the long term, favoring the adoption of dysfunctional eating behaviors. Objective: To test the correlation between anxiety level and weight recurrence in women in the late postoperative period of bariatric and metabolic surgery. Methods: Fifty adult women with at least 24 months after bariatric and metabolic surgery were evaluated. Sociodemographic data (age, income and level of education) and psychological monitoring were collected. Anthropometric data (weight and height) were measured. To assess the level of anxiety symptoms, the Beck Anxiety Inventory was used. Results: A mean age of 40.9±11.4 years was found. All had moderate to severe anxiety symptoms. Those who were without psychological support had higher body weight (p=0.049) and greater recurrence of weight (p=0.040). There was a positive correlation between the anxiety score and body weight recurrence, and a negative correlation between the anxiety score and family income. In the linear regression model, the correlation between anxiety score and weight recurrence (B=0.276; CI 0.003; 0.594; p=0.048) and income (B=-0.310; CI -0.004; 0.000; p=0.027) remained significant. However, when adding the variable "surgery time", there was a loss of significance between anxiety and weight recurrence (B=0.270; CI -0.040; -0.624; p=0.083), but the correlation with income was maintained (B=-0.310; CI -0.004; -0.000; p=0.029). Conclusions: We emphasize the importance of financial support in the postoperative period, due to treatment costs, in addition to maintaining monitoring with the multidisciplinary team in the long term.

A Multivariate Model for Prediction of Obstructive Coronary Disease in Patients with Acute Chest Pain: Development and Validation.

BACKGROUND:: Currently, there is no validated multivariate model to predict probability of obstructive coronary disease in patients with acute chest pain. OBJECTIVE:: To develop and validate a multivariate model to predict coronary artery disease (CAD) based on variables assessed at admission to the coronary care unit (CCU) due to acute chest pain. METHODS:: A total of 470 patients were studied, 370 utilized as the derivation sample and the subsequent 100 patients as the validation sample. As the reference standard, angiography was required to rule in CAD (stenosis ≥ 70%), while either angiography or a negative noninvasive test could be used to rule it out. As predictors, 13 baseline variables related to medical history, 14 characteristics of chest discomfort, and eight variables from physical examination or laboratory tests were tested. RESULTS:: The prevalence of CAD was 48%. By logistic regression, six variables remained independent predictors of CAD: age, male gender, relief with nitrate, signs of heart failure, positive electrocardiogram, and troponin. The area under the curve (AUC) of this final model was 0.80 (95% confidence interval [95%CI] = 0.75 - 0.84) in the derivation sample and 0.86 (95%CI = 0.79 - 0.93) in the validation sample. Hosmer-Lemeshow's test indicated good calibration in both samples (p = 0.98 and p = 0.23, respectively). Compared with a basic model containing electrocardiogram and troponin, the full model provided an AUC increment of 0.07 in both derivation (p = 0.0002) and validation (p = 0.039) samples. Integrated discrimination improvement was 0.09 in both derivation (p < 0.001) and validation (p < 0.0015) samples. CONCLUSION:: A multivariate model was derived and validated as an accurate tool for estimating the pretest probability of CAD in patients with acute chest pain. FUNDAMENTO:: Atualmente, não existe um modelo multivariado validado para predizer a probabilidade de doença coronariana obstrutiva em pacientes com dor torácica aguda. OBJETIVO:: Desenvolver e validar um modelo multivariado para predizer doença arterial coronariana (DAC) com base em variáveis avaliadas à admissão na unidade coronariana (UC) devido a dor torácica aguda. MÉTODOS:: Foram estudados um total de 470 pacientes, 370 utilizados como amostra de derivação e os subsequentes 100 pacientes como amostra de validação. Como padrão de referência, a angiografia foi necessária para descartar DAC (estenose ≥ 70%), enquanto a angiografia ou um teste não invasivo negativo foi utilizado para confirmar a doença. Foram testadas como preditoras 13 variáveis basais relacionadas à história médica, 14 características de desconforto torácico e oito variáveis relacionadas ao exame físico ou testes laboratoriais. RESULTADOS:: A prevalência de DAC foi de 48%. Por regressão logística, seis variáveis permaneceram como preditoras independentes de DAC: idade, gênero masculino, alívio com nitrato, sinais de insuficiência cardíaca, e eletrocardiograma e troponina positivos. A área sob a curva (area under the curve, AUC) deste modelo final foi de 0,80 (intervalo de confiança de 95% [IC95%] = 0,75 - 0,84) na amostra de derivação e 0,86 (IC95% = 0,79 - 0,93) na amostra de validação. O teste de Hosmer-Lemeshow indicou uma boa calibração em ambas as amostras (p = 0,98 e p = 0,23, respectivamente). Em comparação com o modelo básico contendo eletrocardiograma e troponina, o modelo completo ofereceu um incremento na AUC de 0,07 tanto na amostra de derivação (p = 0,0002) quanto na de validação (p = 0,039). A melhoria na discriminação integrada foi de 0,09 nas amostras de derivação (p < 0,001) e validação (p < 0,0015). CONCLUSÃO:: Um modelo multivariado foi derivado e validado como uma ferramenta acurada para estimar a probabilidade pré-teste de DAC em pacientes com dor torácica aguda.

Insumos para manejo do Diabetes Tipo 1 durante o distanciamento social por COVID-19 no Brasil / Supplies for Type 1 Diabetes management during COVID-19 social distancing in Brazil

O estudo analisou fatores socioeconômicos associados à aquisição de insumos para manejo da glicemia por pessoas com Diabetes Mellitus tipo 1 durante o distanciamento social pela Pandemia de COVID-19 no Brasil. Pesquisa transversal com coleta de dados realizada durante 21 dias do mês de julho de 2020, com um formulário online sobre dados socioeconômicos e aquisição de insumos para monitorização glicêmica. Foi aplicado o teste Qui-Quadrado de Pearson com análise de resíduos ajustados (p<0,05). Participaram 472 adultos de ambos os sexos. Foram encontradas associações entre o tipo de aparelho utilizado para monitorização glicêmica (glicosímetro ou sistema Flash) e renda (p<0,000), escolaridade (p=0,007), macrorregiões (p=0,049) e tipo de cidade (p=0,043); entre aquisição de insulinas e renda (p<0,000), macrorregião (p=0,027) e tipo de bairro (p=0,003); entre aquisição de fitas reagentes e renda (p<0,000); entre aquisição de lancetas e renda (p=0,001), tipo de cidade (p=0,035) e de bairro (p=0,010); entre o uso de Sistema Flash e renda (p<0,000) e tipo de bairro (p=0,006). Os resultados expõem as desigualdades sociais na aquisição de insumos para manejo da glicemia por pessoas com Diabetes Tipo 1 durante a Pandemia no Brasil.

This study analyzed socioeconomic factors related with the acquisition of supplies for blood glucose management by people with Type 1 Diabetes Mellitus during social distancing due to the COVID-19 Pandemic in Brazil. This was a cross-sectional study with data collected during 21 days in July 2020, by an online form on socioeconomic data and acquisition of supplies for glycemic monitoring. This research applied Pearson's Chi-Squared test with adjusted residual analysis (p<0.05). 472 adults of both sexes participated. Relationships were found between the type of device used for blood glucose monitoring (glucometer or Flash system) and income (p<0.000), education (p=0.007), macro-regions (p=0.049), and type of city (p=0.043); between insulin acquisition and income (p<0.000), macro-region (p=0.027) and type of neighborhood (p=0.003); between acquisition of reagent strips and income (p<0.000); between acquisition of lancets and income (p=0.001), type of city (p=0.035) and neighborhood (p=0.010); between the use of Flash System and income (p<0.000) and type of neighborhood (p=0.006). The results expose the social inequalities in the acquisition of supplies for blood glucose management by people with Type 1 Diabetes during the Pandemic in Brazil.

Zero Calcium Score as a Filter for Further Testing in Patients Admitted to the Coronary Care Unit with Chest Pain.

BACKGROUND:: The accuracy of zero coronary calcium score as a filter in patients with chest pain has been demonstrated at the emergency room and outpatient clinics, populations with low prevalence of coronary artery disease (CAD). OBJECTIVE:: To test the gatekeeping role of zero calcium score in patients with chest pain admitted to the coronary care unit (CCU), where the pretest probability of CAD is higher than that of other populations. METHODS:: Patients underwent computed tomography for calcium scoring, and obstructive CAD was defined by a minimum 70% stenosis on invasive angiography. RESULTS:: In 146 patients studied, the prevalence of CAD was 41%. A zero calcium score was present in 35% of the patients. The sensitivity and specificity of zero calcium score yielded a negative likelihood ratio of 0.16. After logistic regression adjustment for pretest probability, zero calcium score was independently associated with lower odds of CAD (OR = 0.12, 95%CI = 0.04-0.36), increasing the area under the ROC curve of the clinical model from 0.76 to 0.82 (p = 0.006). Zero calcium score provided a net reclassification improvement of 0.20 (p = 0.0018) over the clinical model when using a pretest probability threshold of 10% for discharging without further testing. In patients with pretest probability < 50%, zero calcium score had a negative predictive value of 95% (95%CI = 83%-99%), with a number needed to test of 2.1 for obtaining one additional discharge. CONCLUSION:: Zero calcium score substantially reduces the pretest probability of obstructive CAD in patients admitted to the CCU with acute chest pain. (Arq Bras Cardiol. 2017; [online].ahead print, PP.0-0). FUNDAMENTO:: A acurácia do escore de cálcio coronário zero como um filtro nos pacientes com dor torácica aguda tem sido demonstrada na sala de emergência e nos ambulatórios, populações com baixa prevalência de doença arterial coronariana (DAC). OBJETIVOS:: Testar o papel do escore de cálcio zero como filtro nos pacientes com dor torácica admitidos numa unidade coronariana intensiva (UCI), na qual a probabilidade pré-teste de DAC é maior do que em outras populações. MÉTODOS:: Pacientes foram submetidos a tomografia computadorizada para quantificar o escore de cálcio, DAC obstrutiva foi definida por uma estenose mínima de 70% na cineangiocoronariografia invasiva. Um escore clínico para estimar a probabilidade pré-teste de DAC obstrutiva foi criado em amostra de 370 pacientes, usado para definir subgrupos na definição de valores preditivos negativos do escore zero. RESULTADOS:: Em 146 pacientes estudados, a prevalência de DAC foi 41% e o escore de cálcio zero foi demonstrado em 35% deles. A sensibilidade e a especificidade para escore de cálcio zero resultaram numa razão de verossimilhança negativa de 0,16. Após ajuste com um escore clínico com a regressão logística para a probabilidade pré-teste, o escore de cálcio zero foi preditor independente associado a baixa probabilidade de DAC (OR = 0,12, IC95% = 0,04-0,36), aumentando a área abaixo da curva ROC do modelo clínico de 0,76 para 0,82 (p = 0,006). Considerando a probabilidade de DAC < 10% como ponto de corte para alta precoce, o escore de cálcio aumentou a proporção de pacientes para alta precoce de 8,2% para 25% (NRI = 0,20; p = 0,0018). O escore de cálcio zero apresentou valor preditivo negativo de 90%. Em pacientes com probabilidade pré-teste < 50%, o valor preditivo negativo foi 95% (IC95% = 83%-99%). CONCLUSÃO:: O escore de cálcio zero reduz substancialmente a probabilidade pré-teste de DAC obstrutiva em pacientes internados em UCI com dor torácica aguda. (Arq Bras Cardiol. 2017; [online].ahead print, PP.0-0).

Incremental Prognostic Value of the Incorporation of Clinical Data Into Coronary Anatomy Data in Acute Coronary Syndromes: SYNTAX-GRACE Score.

BACKGROUND: When performing coronary angiography in patients with acute coronary syndrome (ACS), the anatomical extent of coronary disease usually prevails in the prognostic reasoning. It has not yet been proven if clinical data should be accounted for in risk stratification together with anatomical data. OBJECTIVE: To test the hypothesis that clinical data increment the prognostic value of anatomical data in patients with ACS. METHODS: Patients admitted with objective criteria for ACS and who underwent angiography during hospitalization were included. Primary outcome was defined as in-hospital cardiovascular death, and the prognostic value of the SYNTAX Score (anatomical data) was compared to that of the SYNTAX-GRACE Score, which resulted from the incorporation of the GRACE Score into the SYNTAX score. The Integrated Discrimination Improvement (IDI) was calculated to evaluate the SYNTAX-GRACE Score ability to correctly reclassify information from the traditional SYNTAX model. RESULTS: This study assessed 365 patients (mean age, 64 ± 14 years; 58% male). In-hospital cardiovascular mortality was 4.4%, and the SYNTAX Score was a predictor of that outcome with a C-statistic of 0.81 (95% CI: 0.70 - 0.92; p < 0.001). The GRACE Score was a predictor of in-hospital cardiac death independently of the SYNTAX Score (p < 0.001, logistic regression). After incorporation into the predictive model, the GRACE Score increased the discrimination capacity of the SYNTAX Score from 0.81 to 0.92 (95% CI: 0.87 - 0.96; p = 0.04). CONCLUSION: In patients with ACS, clinical data complement the prognostic value of coronary anatomy. Risk stratification should be based on the clinical-anatomical paradigm, rather than on angiographic data only.

Accuracy of gestalt perception of acute chest pain in predicting coronary artery disease.

AIM: To test accuracy and reproducibility of gestalt to predict obstructive coronary artery disease (CAD) in patients with acute chest pain. METHODS: We studied individuals who were consecutively admitted to our Chest Pain Unit. At admission, investigators performed a standardized interview and recorded 14 chest pain features. Based on these features, a cardiologist who was blind to other clinical characteristics made unstructured judgment of CAD probability, both numerically and categorically. As the reference standard for testing the accuracy of gestalt, angiography was required to rule-in CAD, while either angiography or non-invasive test could be used to rule-out. In order to assess reproducibility, a second cardiologist did the same procedure. RESULTS: In a sample of 330 patients, the prevalence of obstructive CAD was 48%. Gestalt's numerical probability was associated with CAD, but the area under the curve of 0.61 (95%CI: 0.55-0.67) indicated low level of accuracy. Accordingly, categorical definition of typical chest pain had a sensitivity of 48% (95%CI: 40%-55%) and specificity of 66% (95%CI: 59%-73%), yielding a negligible positive likelihood ratio of 1.4 (95%CI: 0.65-2.0) and negative likelihood ratio of 0.79 (95%CI: 0.62-1.02). Agreement between the two cardiologists was poor in the numerical classification (95% limits of agreement = -71% to 51%) and categorical definition of typical pain (Kappa = 0.29; 95%CI: 0.21-0.37). CONCLUSION: Clinical judgment based on a combination of chest pain features is neither accurate nor reproducible in predicting obstructive CAD in the acute setting.

Cooking habits and food choices of individuals with Type 1 Diabetes Mellitus during the pandemic of COVID-19 / Hábito de cozinhar e escolhas alimentares de indivíduos com Diabetes Mellitus Tipo 1 durante a pandemia de COVID-19

ABSTRACT Objective To verify the association between cooking habits, socioeconomic data, and food choices of individuals with Type 1 Diabetes Mellitus during the pandemic of COVID-19. Methods Transversal study with individuals with Type 1 Diabetes Mellitus carried out in July 2020. Socioeconomic data and information about social distancing and food practices were collected with an online form. The research was approved by the university's Ethics and Research Committee (Process number 4.147.663). Results Out of the 472 participants, 50.9% reported that they have been cooking more during the pandemic. An association between cooking more and having a university degree (p<0.000) was observed. Not being able to comply with social distancing rules because of work necessities was associated with not cooking (p=0.006). Cooking more during the quarantine was associated with eating less than five meals per day (p=0.04), having an appropriate consumption of fruits (p=0.02) and vegetables (p=0.04), and increased water intake (p=0.01). Conclusion In Brazil, the habit of cooking during the pandemic may represent an increase in domestic work, reinforced by social inequalities. Therefore, comprehending the cooking habits and food choices of people with diabetes may widen the perspectives of health professionals involved in the treatment of the disease and contribute to the elaboration of public policies that take the country's inequalities into account. We emphasize the importance of investing in policies that encourage the development of culinary skills, as well as the habit of cooking as part of the actions of Food and Nutrition Education.

RESUMO Objetivo Verificar associação entre o hábito de cozinhar, dados socioeconômicos e escolhas alimentares de indivíduos com Diabetes Mellitus tipo 1 durante a pandemia de COVID-19. Método Estudo transversal realizado com indivíduos com Diabetes Mellitus tipo 1 durante julho de 2020. A partir de um formulário on-line foram coletados dados socioeconômicos, demográficos, informações sobre o distanciamento social e práticas alimentares durante a quarentena. A pesquisa foi aprovada pelo Comitê de Ética em Pesquisa (parecer 4.147.663). Resultados Dos 472 participantes, 50,9% relataram estar cozinhando mais durante a quarentena. Observou-se uma associação entre cozinhar mais e ter ensino superior (p<0,000). Não estar realizando distanciamento social porque precisava trabalhar esteve associado a não cozinhar (p=0,006). Quanto à alimentação, cozinhar mais durante a quarentena estava associado a consumir menos de cinco refeições ao dia (p=0,04), ter consumo adequado de frutas (p=0,02) e hortaliças (p=0,04) e ter aumentado a ingestão de água (p=0,01). Conclusão No Brasil, o hábito de cozinhar durante a pandemia pode representar um aumento do trabalho doméstico, ocasionado pelas desigualdades sociais. Portanto, compreender esse hábito e as escolhas alimentares de pessoas com diabetes, pode ampliar a visão dos profissionais de saúde envolvidos no tratamento e contribuir com a elaboração de políticas públicas que levem em consideração as desigualdades do país. Ressaltamos a importância do investimento em políticas que estimulem o desenvolvimento das habilidades culinárias, bem como do hábito de cozinhar no âmbito das ações de Educação Alimentar e Nutricional.

Comparison of ACUITY and CRUSADE Scores in Predicting Major Bleeding during Acute Coronary Syndrome.

BACKGROUND: The ACUITY and CRUSADE scores are validated models for prediction of major bleeding events in acute coronary syndrome (ACS). However, the comparative performances of these scores are not known. OBJECTIVE: To compare the accuracy of ACUITY and CRUSADE in predicting major bleeding events during ACS. METHODS: This study included 519 patients consecutively admitted for unstable angina, non-ST-elevation or ST-elevation myocardial infarction. The scores were calculated based on admission data. We considered major bleeding events during hospitalization and not related to cardiac surgery, according to the Bleeding Academic Research Consortium (BARC) criteria (type 3 or 5: hemodynamic instability, need for transfusion, drop in hemoglobin ≥ 3 g, and intracranial, intraocular or fatal bleeding). RESULTS: Major bleeding was observed in 31 patients (23 caused by femoral puncture, 5 digestive, 3 in other sites), an incidence of 6%. While both scores were associated with bleeding, ACUITY demonstrated better C-statistics (0.73, 95% CI = 0.63 - 0.82) as compared with CRUSADE (0.62, 95% CI = 0.53 - 0.71; p = 0.04). The best performance of ACUITY was also reflected by a net reclassification improvement of + 0.19 (p = 0.02) over CRUSADE's definition of low or high risk. Exploratory analysis suggested that the presence of the variables 'age' and 'type of ACS' in ACUITY was the main reason for its superiority. CONCLUSION: The ACUITY Score is a better predictor of major bleeding when compared with the CRUSADE Score in patients hospitalized for ACS.

Does C-reactive protein add prognostic value to GRACE score in acute coronary syndromes?

BACKGROUND: The incremental prognostic value of plasma levels of C-reactive protein (CRP) in relation to GRACE score has not been established in patients with acute coronary syndrome (ACS) with non-ST segment elevation. OBJECTIVE: To test the hypothesis that CRP measurements at admission increases the prognostic value of GRACE score in patients with ACS. METHODS: A total of 290 subjects, consecutively admitted for ACS, with plasma material obtained upon admission CRP measurement using a high-sensitivity method (nephelometry) were studied. Cardiovascular outcomes during hospitalization were defined by the combination of death, nonfatal myocardial infarction or nonfatal refractory angina. RESULTS: The incidence of cardiovascular events during hospitalization was 15% (18 deaths, 11 myocardial infarctions, 13 angina episodes) with CRP showing C-statistics of 0.60 (95% CI = 0.51-0.70, p = 0.034) in predicting these outcomes. After adjustment for the GRACE score, elevated CRP (defined as the best cutoff point) tended to be associated with hospital events (OR = 1.89, 95% CI = 0.92 to 3.88, p = 0.08). However, the addition of the variable elevated CRP in the GRACE model did not result in significant increase in C-statistics, which ranged from 0.705 to 0.718 (p = 0.46). Similarly, there was no significant reclassification of risk with the addition of CRP in the predictor model (net reclassification = 5.7 %, p = 0.15). CONCLUSION: Although CRP is associated with hospital outcomes, this inflammatory marker does not increase the prognostic value of the GRACE score.

Prognostic value of TIMI score versus GRACE score in ST-segment elevation myocardial infarction.

BACKGROUND: The TIMI Score for ST-segment elevation myocardial infarction (STEMI) was created and validated specifically for this clinical scenario, while the GRACE score is generic to any type of acute coronary syndrome. OBJECTIVE: Between TIMI and GRACE scores, identify the one of better prognostic performance in patients with STEMI. METHODS: We included 152 individuals consecutively admitted for STEMI. The TIMI and GRACE scores were tested for their discriminatory ability (C-statistics) and calibration (Hosmer-Lemeshow) in relation to hospital death. RESULTS: The TIMI score showed equal distribution of patients in the ranges of low, intermediate and high risk (39 %, 27 % and 34 %, respectively), as opposed to the GRACE Score that showed predominant distribution at low risk (80 %, 13 % and 7%, respectively). Case-fatality was 11%. The C-statistics of the TIMI score was 0.87 (95%CI = 0.76 to 0.98), similar to GRACE (0.87, 95%CI = 0.75 to 0.99) - p = 0.71. The TIMI score showed satisfactory calibration represented by χ2 = 1.4 (p = 0.92), well above the calibration of the GRACE score, which showed χ2 = 14 (p = 0.08). This calibration is reflected in the expected incidence ranges for low, intermediate and high risk, according to the TIMI score (0 %, 4.9 % and 25 %, respectively), differently to GRACE (2.4%, 25% and 73%), which featured middle range incidence inappropriately. CONCLUSION: Although the scores show similar discriminatory capacity for hospital death, the TIMI score had better calibration than GRACE. These findings need to be validated populations of different risk profiles.
