Factors associated with diet quality among Brazilian individuals with cardiovascular diseases.

BACKGROUND: An individual's dietary pattern contributes in different ways to the prevention and control of recurrent cardiovascular events. However, the quality of the diet is influenced by several factors. The present study aimed to evaluate the quality of the diet of individuals with cardiovascular diseases and determine whether there is an association between sociodemographic and lifestyle factors. METHODS: This is a cross-sectional study carried out with individuals with atherosclerosis (coronary artery disease, cerebrovascular disease or peripheral arterial disease) recruited from 35 reference centres for the treatment of cardiovascular disease in Brazil. Diet quality was assessed according to the Modified Alternative Healthy Eating Index (mAHEI) and stratified into tertiles. For comparing two groups, the Mann-Whitney or Pearson's chi-squared tests were used. However, for comparing three or more groups, analysis of variance or Kruskal-Wallis was used. For the confounding analysis, a multinomial regression model was used. p < 0.05 was considered statistically significant. RESULTS: In total, 2360 individuals were evaluated: 58.5% male and 64.2% elderly. The median (interquartile range [IQR]) of the mAHEI was 24.0 (20.0-30.0), ranging from 0.4 to 56.0 points. When comparing the odds ratios (ORs) for the low (first tertile) and medium (second tertile) diet quality groups with the high-quality group (third tertile), it was observed that there was an association between diet quality with a family income of 1.885 (95% confidence intervals [CI] = 1.302-2.729) and 1.566 (95% CI = 1.097-2.235), as well as physical activity of 1.391 (95% CI = 1.107-1.749) and 1.346 (95% CI = 1.086-1.667), respectively. In addition, associations were observed between diet quality and region of residence. CONCLUSIONS: A low-quality diet was associated with family income, sedentarism and geographical area. These data are extremely relevant to assist in coping with cardiovascular disease because they enable an assessment of the distribution of these factors in different regions of the country.

Surgical periodontal treatment of a patient with dentinal hypersensitivity after bariatric surgery: a case report.

The aim of this report is to present the clinical case of a patient with severe symptoms of dentinal hypersensitivity after bariatric surgery. A 40-year-old woman had a complaint of hypersensitivity in all teeth after bariatric surgery to treat morbid obesity. The patient had multiple sites of gingival recession associated with pain symptoms that were characteristic of dentinal hypersensitivity. Subepithelial connective tissue grafting was performed, using either coronal flap displacement techniques or a tunnel-type approach, at the sites of gingival recession and/or dentinal hypersensitivity. Surgery resulted in gains of keratinized mucosa and root surface coverage as well as regression of pain. Patients who undergo bariatric surgery should be monitored for development of oral health-related complications.

Nonalcoholic steatohepatitis in morbid obese patients: coffee consumption vs. disease severity.

INTRODUCTION: Obesity correlates with nonalcoholic fatty liver disease (NAFLD) and occurs in 90 to 100% of severely obese individuals (body mass index [BMI] > 35 kg/m2). Coffee consumption (CC) has been associated with reduced progression of fibrosis in both hepatitis C infection and NAFLD; however, this topic is still under discussion when this liver disease affects severely obese individuals. OBJECTIVE: To assess the association between CC, insulin resistance (IR) and histological NAFLD morbid obese patients. MATERIAL AND METHODS: Cross-sectional study, including obese individuals undergoing bariatric surgery, liver biopsy and histological diagnosis between September 2013 and August 2014. The patients were classified into 3 groups according to their weekly CC: 0- 239.9 mL; 240-2099.9 mL and ≥ 2100 mL. RESULTS: A total of 112 obese individuals were included (BMI = 41.9 ± 4.3 kg/m2), with a mean age of 34.7 ± 7.4 years; 68.6% were women. CC was reported by 72.3% of patients. There were no statistical significant differences between groups regarding the presence of IR (84.8% vs. 74.2% vs. 75.9%; p = 0.536). Progressively higher percentages of individuals with normal liver histology were observed (14.7% vs. 21.9% vs. 24.3%). NASH (65.7% vs. 70.3% vs. 57.5%) were observed among those who consumed greater coffee volumes (p = 0.812). In conclusion, obese individuals with elevated CC exhibited lower frequencies of NASH, although with no statistical significance in this sample.

Dietary Adequacy of Individuals with Cardiovascular Disease According to Clinical Guidelines in the Brazilian Cardioprotective Nutritional (BALANCE). / Adequação Alimentar de Indivíduos com Doença Cardiovascular Conforme Diretrizes Clínicas no Programa Alimentar Brasileiro Cardioprotetor.

BACKGROUND: Achieving nutritional goals established by scientific societies is a constant challenge and not always achieved. OBJECTIVE: To investigate the dietary adequacy of individuals with cardiovascular disease (CVD), participants in the Cardioprotective Brazilian Food Program residing in the Northeast region of Brazil, according to the recommendations of the Brazilian Society of Cardiology (SBC). METHODS: Cross-sectional analysis with data from the study implementing the Brazilian Cardioprotective Diet (DICA BR), which evaluated individuals with CVD treated in specialized cardiovascular health centers in eight states in the Northeast region. Food consumption was obtained by 24-hour dietary records and dietary adequacy followed SBC recommendations. Values of p < 0.05 were considered significant. RESULTS: 647 patients were studied, with a mean (standard deviation) age of 63.1 (9.4) years, 50.2% of whom were female. When evaluating food intake, a low adequacy of carbohydrates (52.3%), proteins (70.9%), lipids (38.8%), and fiber (22.4%) was observed. It was observed that the majority of women consumed a low-protein diet (59.2%) and the elderly had a greater inadequacy in carbohydrate consumption (52.6%). Regarding sodium intake, men had a higher intake (72.9%), while the elderly showed a 13% reduction. Furthermore, it was shown that men ate more fiber (28.1%) and individuals with higher education had a high consumption of saturated fatty acids (70.5%). CONCLUSIONS: Most individuals did not achieve the recommended dietary therapy goals for secondary cardiovascular prevention. The findings of the present study reinforce the need to implement structured strategies to encourage healthy eating habits in these individuals.

FUNDAMENTO: Alcançar as metas nutricionais estabelecidas pelas sociedades científicas é um desafio constante e nem sempre alcançado. OBJETIVO: Investigar a adequação alimentar de indivíduos com doença cardiovascular (DCV), participantes do Programa Alimentar Brasileiro Cardioprotetor residentes da região Nordeste do Brasil, segundo as recomendações da Sociedade Brasileira de Cardiologia (SBC). MÉTODOS: Análise transversal com dados do estudo de implementação da Dieta Cardioprotetora Brasileira (DICA BR) que avaliou indivíduos com DCV, atendidos em centros especializados em saúde cardiovascular em oito estados do Nordeste. O consumo alimentar foi obtido por recordatório alimentar de 24 horas e a adequação da dieta seguiu as recomendações da SBC. Foram considerados significantes valores de p < 0,05. RESULTADOS: Foram estudados 647 pacientes, com média (desvio padrão) de idade de 63,1 (9,4) anos, sendo 50,2% do sexo feminino. Na avaliação da ingestão alimentar, observou-se baixa adequação de carboidratos (52,3%), proteínas (70,9%), lipídios (38,8%) e fibras (22,4%). Observou-se que a maioria das mulheres consumia dieta hipoproteica (59,2%) e idosos tinham maior inadequação no consumo de carboidratos (52,6%). Em relação a ingestão de sódio, os homens apresentaram maior ingestão (72,9%), enquanto os idosos apresentaram redução de 13%. Além disso, foi demonstrado que os homens ingeriam mais fibras (28,1%) e indivíduos com maior escolaridade tinham um consumo elevado de ácidos graxos saturados (70,5%). CONCLUSÕES: A maioria dos indivíduos não alcançou as metas dietoterápicas preconizadas para prevenção cardiovascular secundária. Os achados do presente estudo reforçam a necessidade de implementação de estratégias estruturadas, a fim de estimular hábitos alimentares saudáveis nesses indivíduos.

Energy and nutrient intake by people with and without sarcopenia diagnosed by the European Working Group on Sarcopenia in Older People: a systematic review and meta-analysis.

CONTEXT: There is growing evidence that insufficient dietary intake is associated with sarcopenia. OBJECTIVE: In this systematic review and meta-analysis, the energy and nutrient intakes by people with and without sarcopenia were compared using only the European Working Group on Sarcopenia in Older People 2010 (EWGSOP1) and 2019 (EWGSOP2) consensus diagnostic criteria. DATA SOURCES: Only observational studies that compared energy and nutrient intake from food alone by individuals with and without sarcopenia were included. Studies were searched in the following databases: Embase, PubMed, Scopus, Web of Science, Lilacs, Ovid, and Scopus. The review followed the PRISMA checklist and submitted the protocol to PROSPERO. DATA EXTRACTION: Data were extracted by 2 authors independently. The methodological quality of the studies was assessed using the Newcastle-Ottawa scale. DATA ANALYSIS: A total of 8648 articles were identified and 12 were selected. Among individuals with sarcopenia, lower intakes of energy and some nutrients, mainly with antioxidant properties, were observed compared with those without sarcopenia. Meta-analyses showed that individuals with sarcopenia consume fewer calories/day than individuals without sarcopenia (n = 10 studies; standardized mean difference (SMD) -0.15; 95% confidence interval: -0.29, -0.01) diagnosed by EWGSOP1 and EWGSOP2. Individuals with sarcopenia consume less omega-3, folate, magnesium, phosphorus, selenium, zinc, and vitamins C, D, and E when compared with those without sarcopenia. CONCLUSION: The results of the present study suggest that insufficient intake of energy and nutrients with antioxidant potential may be associated with sarcopenia. SYSTEMATIC REVIEW REGISTRATION: PROSPERO registration no. CRD 42020195698.

Assessment of sleep and stress level in individuals with chronic pain.

Introduction: The experience of living with chronic pain allows for the appearance of changes in sleep patterns, mood, and stress levels. Objective: To describe the phases of stress and the quality of sleep in patients with chronic pain. Material and Methods: Cross-sectional study carried out at the pain clinic of the HUPES Complex, Salvador-Bahia. Data collection between March 2016 and November 2017. Instruments: Sociodemographic questionnaire, Numerical Pain Scale (EVN), Mini-Sleep Questionnaire (MSQ), and Stress Symptoms Inventory for LIPP adults (ISSL). Categorical variables were expressed by absolute and relative frequency and quantitative variables by means and standard deviation (SD). The comparison of categorical variables was performed using the chi-square test. Values of p<0.05 were considered statistically significant. Results: Mean age (standard deviation) of 50.0 (10) years, 89.6% of whom were female. Predominance of people with a partner, with religion, high school, and unemployed or removed by the INSS. They have severe sleep disorders, severe pain, and the presence of stress in the resistance phase. Most subjects reveal that they have improved with the treatment and have moderate self-esteem and personal satisfaction, despite the presence of anxious and depressive symptoms. Conclusion: Chronic pain has a very significant impact on life, increasing the level of stress, compromising and limiting daily activities, and showing more presence of anxious and depressive symptoms in people who suffer from chronic pain.

Prevalence of sarcopenia using different methods in patients with non-alcoholic fatty liver disease.

BACKGROUND: Sarcopenia is a clinical condition associated with several liver diseases and it includes non-alcoholic fatty liver disease (NAFLD) in its broad spectrum as steatosis, steatohepatitis and fibrosis. However, the criteria to define sarcopenia are diverse, and even those established in consensus have been discussed regarding their performance in making an accurate diagnosis. AIM: To evaluate the prevalence of sarcopenia, using different methods, in patients with NAFLD, and its association with clinical-anthropometric parameters. METHODS: This was an observational study of outpatients with NAFLD. Sarcopenia was defined by the European Working Group Consensus on Sarcopenia in Older People of 2010 (EWGSOP1) and 2018 (EWGSOP2). The skeletal muscle index was used to estimate muscle mass, handgrip strength was assessed using the dynamometer and physical performance by walking a distance of four meters at usual walking speed. The non-invasive fibrosis scores, fibrosis-4 (FIB-4) index and Aspartate aminotransferase to platelet ratio index (APRI), were used to assess the absence and presence of fibrosis. RESULTS: Fifty-seven individuals with NAFLD were evaluated, the mean age (SD) was 52.7 (11.3) years and 75.4% were female. Fibrosis assessed by FIB-4 and APRI was observed in 3.7% and 16.6% of patients with NAFLD, respectively. The diagnosis of sarcopenia was identified only by EWGSOP1 in 3.5% of NAFLD patients, and the prevalence of probable/pre-sarcopenia was higher using the EWGSOP2 consensus at 26.3%, when compared to 1.8% with EWGSOP1. Sarcopenia defined by EWGSOP1, was associated with grade I steatosis, but without overweight (P < 0.05). An association between sarcopenia and fibrosis was not observed (P > 0.05). EWGSOP2 showed a greater number of patients with probable sarcopenia, and who were overweight (12 (80.0%)), with a higher degree of steatosis [11 (73.3%) and presence of fibrosis (1 (6.7%), FIB-4 and 3 (20.0%), APRI] compared to EWGSOP1 [1 (100%), 0 (0.0%), 0 (0.0%), FIB-4 and 0 (0.0%), APRI, respectively]. CONCLUSION: The present study showed that sarcopenia in NAFLD was not predominant in patients without fibrosis, by both diagnostic methods. In addition, the prevalence of probable sarcopenia also depends on the method applied.

Fractured orbital wall reconstruction with an auricular cartilage graft or absorbable polyacid copolymer.

OBJECTIVE: The objective of the study was to compare the functional and aesthetic results of fractured orbital wall reconstruction with an auricular cartilage graft or absorbable polyacid copolymer. MATERIALS AND METHODS: Twenty patients with blow-out orbital fracture/orbital floor associated or not with the medial wall were assessed by the same craniofacial surgical group. All were evaluated preoperatively and postoperatively by an ophthalmologist for diplopia, enophthalmos, exophthalmos, sensitivity, ophthalmic reflexes, intraocular pressure, and visual field.The patients were subjected to a preoperative facial multislice computed tomographic scan, repeated 6 months after surgery. Eight patients underwent reconstruction with an auricular cartilage graft, and 12 patients, with blade absorbable polyacid copolymer. Subtarsal access was used for all patients. RESULTS: Two patients showed temporary ectropion, 1 in each group. All patients presented satisfactory ocular function, and all tests revealed good orbital delineation, orbital symmetry, periorbital sinus individualization, and reduction of blow-out. CONCLUSIONS: The blow-out orbital wall reconstruction can be performed with the use of an auricular cartilage or with a blade absorbable copolymer without differences regarding functional or aesthetic complications and sequelae.

The possible benefits of vitamin D in COVID-19.

Molecular studies have demonstrated the importance of the exacerbated immune response to SARS-CoV-2 infection, called the cytokine storm, in more severe COVID-19. The pathophysiology is complex and involves several homeostatic factors; among them, a deficit of vitamin D draws attention because of its high frequency in the population. Some evidence suggests that people with low serum vitamin D levels have worse outcomes, often requiring intensive care. This review analyzed the studies available in the global literature addressing the benefits of vitamin D in COVID-19, relating serum levels to the severity of the disease, and indicating vitamin D as a possible prophylactic and therapy in infection.

Influence of nutritional assistance on mortality by COVID-19 in critically ill patients.

BACKGROUND & AIMS: Evidence suggests the existence of an association between the institution of nutritional therapy and clinical outcomes in patients with critical COVID-19. Thus, the aim of this study was to evaluate the influence of nutritional assistance on COVID-19 mortality in patients admitted to intensive care units (ICU). METHODS: This is a subset of the cohort "Influence of nutritional therapy on clinical prognosis in patients with COVID-19: a multicenter retrospective cohort study". Clinical and nutrition assistance information (type of assistance, evaluation of anthropometric status, and time of introduction of nutritional therapy) and presence of diabetes, hypertension and previous respiratory disease were collected from electronic medical records. To evaluate the association between the variables of interest and mortality, the hazard ratio was estimated. RESULTS: We evaluated 153 critically ill patients ≥18 years old, affected by COVID-19, with a rate of mortality of 77.8%. Among non survivors 58.8% were female, 52.9% aged <65 years, 66.4% had arterial hypertension, 46.2% diabetes mellitus and 81.5% had an early onset of nutritional support. Initiation of nutritional therapy after 48 h (HR: 2.57; 95% CI: 1.57-4.20) and the presence of obesity (HR: 1.55; 95% CI: 1.04-2.31) were associated with higher mortality, even after adjustment for potential confounders. CONCLUSIONS: Our data suggests that the provision of early nutritional therapy should be prioritized, with greater attention directed to obese patients, and the nutritional assistance can contribute favorably to the clinical evolution and prognosis of critically ill patients with COVID-19.

Muscle mass and cellular membrane integrity assessment in patients with nonalcoholic fatty liver disease.

OBJECTIVE: To evaluate the association between muscle mass depletion and compromising of the cell membrane integrity and clinical-anthropometric characteristics in patients with nonalcoholic fatty liver disease. METHODS: This observational study evaluated waist circumference, body mass index, and waist-to-height ratio in patients with nonalcoholic fatty liver disease. Skeletal mass index corrected by weight and impairment of cell membrane integrity were assessed using bioelectrical impedance analysis. RESULTS: In 56 patients, muscle mass depletion was observed in 62.5% and cell membrane impairment in 28.6%. The metabolic syndrome and elevated aspartate aminotransferase were the only clinical factors associated with mass depletion (p<0.05). The linear regression analysis showed association between skeletal mass index and waist-to-height ratio and waist circumference, after adjustments (p<0.05). The phase angle value was not different between those with and without mass depletion, and also it did not have correlation with skeletal mass index and clinical parameters (p>0.05). CONCLUSIONS: The prevalence of mass depletion and cell membrane impairment was higher in patients with nonalcoholic fatty liver disease. The muscle mass depletion was associated with central obesity, aspartate aminotransferase elevated, and metabolic syndrome; however, the phase angle is not associated with clinical and anthropometric data.

Anthropometric clinical indicators of visceral adiposity as predictors of nonalcoholic fatty liver disease.

OBJECTIVE: This study aims to evaluate the role of anthropometric clinical indicators of visceral adiposity as predictors of NAFLD, identifying the cutoff points based on gender. METHODS: This was a cross-sectional study conducted in patients with or without NAFLD. Waist circumference (WC), body mass index (BMI), waist-to-height ratio (WHtR), Conicity Index (C Index), and lipid accumulation product (LAP) were evaluated. RESULTS: A total of 107 individuals were evaluated, of which 46.7% were diagnosed with NAFLD. Individuals with NAFLD presented higher values of WC, BMI, C Index, LAP, and WHtR when compared with those without NAFLD (p<0.05). For the total sample, the indicators WC, BMI, WHtR, LAP, and C Index had an area under the receiver operator characteristic curve (AUC) above 0.87, with no difference in the prediction of NAFLD in both sexes. WHtR (AUC=0.934) was the indicator of visceral adiposity with the best discriminatory power for NAFLD, followed by LAP (0.919), WC (0.912), C Index (0.907), and BMI (0.877). CONCLUSIONS: The anthropometric clinical indicators of visceral adiposity showed high performance, especially the WHtR indicator, as NAFLD predictors.

Thyroid Hormone Levels During Hospital Admission Inform Disease Severity and Mortality in COVID-19 Patients.

Background: Illness severity in patients infected with COVID-19 is variable. Methods: Here, we conducted an observational, longitudinal, and prospective cohort study to investigate serum thyroid hormone (TH) levels in adult COVID-19 patients, admitted between June and August 2020, and to determine whether they reflect the severity or mortality associated with the disease. Results: Two hundred forty-five patients [median age: 62 (49-75) years] were stratified into non-critical (181) and critically ill (64) groups. Fifty-eight patients (23.6%) were admitted to the intensive care unit, and 41 (16.7%) died. Sixteen (6.5%) exhibited isolated low levels of free triiodothyronine (fT3). fT3 levels were lower in critically ill compared with non-critical patients [fT3: 2.82 (2.46-3.29) pg/mL vs. 3.09 (2.67-3.63) pg/mL, p = 0.007]. Serum reverse triiodothyronine (rT3) was mostly elevated but less so in critically ill compared with non-critical patients [rT3: 0.36 (0.28-0.56) ng/mL vs. 0.51 (0.31-0.67) ng/mL, p = 0.001]. The univariate logistic regression revealed correlation between in-hospital mortality and serum fT3 levels (odds ratio [OR]: 0.47; 95% confidence interval [CI 0.29-0.74]; p = 0.0019), rT3 levels (OR: 0.09; [CI 0.01-0.49]; p = 0.006) and the product fT3 × rT3 (OR: 0.47; [CI 0.28-0.74]; p = 0.0026). Serum thyrotropin, free thyroxine, and fT3/rT3 values were not significantly associated with mortality and severity of the disease. A serum cutoff level of fT3 (≤2.6 pg/mL) and rT3 (≤0.38 ng/mL) was associated with 3.46 and 5.94 OR of mortality, respectively. We found three COVID-19 mortality predictors using the area under the receiver operating characteristic (ROC) curve (AUC score): serum fT3 (AUC = 0.66), rT3 (AUC = 0.64), and the product of serum fT3 × rT3 (AUC = 0.70). Non-thyroidal illness syndrome (fT3 < 2.0 pg/mL) was associated with a 7.05 OR of mortality ([CI 1.78-28.3], p = 0.005) and the product rT3 × fT3 ≤ 1.29 with an 8.08 OR of mortality ([CI 3.14-24.2], p < 0.0001). Conclusions: This prospective study reports data on the largest number of hospitalized moderate-to-severe COVID-19 patients and correlates serum TH levels with illness severity, mortality, and other biomarkers to critical illness. The data revealed the importance of early assessment of thyroid function in hospitalized patients with COVID-19, given the good prognostic value of serum fT3, rT3, and fT3 × rT3 product. Further studies are necessary to confirm these observations.

Diabetic Patients with Cardiovascular Disease Show More Metabolic Syndrome than Nondiabetic Patients: Multicentric Study in the Northeast of Brazil.

Background: Diabetes mellitus (DM) is associated with a higher prevalence of metabolic syndrome (MS) and cardiovascular mortality. However, few Brazilian studies evaluated MS in diabetic individuals with cardiovascular disease (CVD). Nevertheless, the objective of this study was to compare the prevalence of MS in cardiac patients with and without DM. Methods: Cross-sectional study of BALANCE Program Trial with patients with CVD, ≥45 years old, who had been attending specialized ambulatories on cardiovascular health, in eight states in the Northeast of Brazil. The components of MS were evaluated by following the criteria of National Cholesterol Education Program's Adult Treatment Panel III (NCEP ATP III) and Joint Interim Statement (JIS). In addition, there were investigated different indexes of abdominal obesity, variables related to lifestyle, and food intake. The statistical analysis included descriptive statistics and the Student's t-test, Mann-Whitney, and chi-squared tests for the comparison of groups. There were significant values of P < 0.05. Results: Six hundred forty-seven individuals were evaluated with average (standard deviation) age of 63.1 (9.3) years, being 50.5% females and 40.3% diabetic patients. When the groups of patients who were diabetic and the nondiabetic ones, the first showed higher percentage of obesity (38.5% vs. 23.2%, P < 0.001), of high waist circumference (84.8% vs. 71.9%; P < 0.001), higher waist-height ratio [0.6 (0.6-0.7) vs. 0.6 (0.5-0.6); P < 0.001], conicity index [1.35 (1.29-1.39) vs. 1.32 (1.27-1.38); P = 0.004], and prevalence of MS, because of the criteria of NCEP ATP III (98.8% vs. 80.4%; P < 0.001), as well as the criteria of JIS (99.2% vs. 89.3%; P < 0.001). The component of higher frequency was high blood pressure and/or hypertension (95.0%), followed by hypertriglyceridemia (93.0%). There were no differences regarding age, lifestyle, and food intake. Conclusions: Diabetic individuals with CVD showed more prevalence of MS and more abdominal obesity than nondiabetic individuals. ClinicalTrials.gov ID: NCT01620398.

Phase angle and metabolic parameters in severely obese patients.

INTRODUCTION: Introduction: obese patients present an inflammatory and metabolic profile that leads to oxidative stress and cellular damage. Phase angle is an indicator of cellular integrity and has been proposed as a prognostic parameter for changes in the metabolic profile. Objective: to investigate the possible association between phase angle and metabolic parameters in obese patients. Material and method: this was a cross-sectional study of adult obese patients who attended a specialized clinic between 2014 and 2016. All patients were ≥ 18 years of age, with a body mass index ≥ 35 kg/m2. All data were obtained from medical records and made part of the clinical protocol. Patients were divided into two groups using a cutoff point for phase angle, and the groups were compared using the Kruskal-Wallis or Chi-squared test for quantitative and categorical variables, respectively. Correlations were identified by Spearman's and Pearson's correlation analyses. All between-group differences were considered statistically significant at p ≤ 0.05. Results: a low phase angle was present in 30.5 % of the 141 patients enrolled in the study. We found an association between low phase angle and presence of hyperuricemia (p = 0.018) when adjusted for waist circumference, dysglycemia, arterial hypertension, and hyperuricemia. There was no correlation between phase angle and the components of body composition. Conclusions: there is an association of phase angle with uric acid levels, but not with other metabolic parameters.

INTRODUCCIÓN: Introducción: los pacientes obesos presentan un perfil inflamatorio y metabólico que provoca estrés oxidativo y daño celular. El ángulo de fase es un indicador de integridad celular que se ha propuesto como parámetro pronóstico de los cambios del perfil metabólico. Objetivo: investigar la posible asociación entre el ángulo de fase y los parámetros metabólicos en pacientes obesos. Material y método: este fue un estudio transversal de pacientes obesos adultos que asistieron a una clínica especializada entre 2014 y 2016. Todos los pacientes tenían ≥ 18 años de edad y un índice de masa corporal ≥ 35 kg/m2. Todos los datos se obtuvieron de los registros médicos y formaron parte del protocolo clínico. Los pacientes se dividieron en dos grupos usando un punto de corte para el ángulo de fase, y los grupos se compararon usando la prueba de Kruskal-Wallis o del chi cuadrado para las variables cuantitativas y categóricas, respectivamente. Las correlaciones se identificaron mediante el análisis de correlación de Spearman y el de Pearson. Todas las diferencias entre grupos se consideraron estadísticamente significativas si p ≤ 0.05. Resultados: se observó un ángulo de fase bajo en el 30,5 % de los 141 pacientes incluidos en el estudio. Encontramos una asociación entre el ángulo de fase bajo y la presencia de hiperuricemia (p = 0.018) cuando se ajustó para la circunferencia de la cintura, la disglucemia, la hipertensión arterial y la hiperuricemia. No hubo correlación entre el ángulo de fase y los componentes de la composición corporal. Conclusiones: el ángulo de fase presenta asociación con los niveles plasmáticos de ácido úrico pero no con otros parámetros metabólicos.

High Prevalence of AH in HIV Patients on ART, in Bahia, Brazil.

INTRODUCTION: The prevalence of arterial hypertension (AH) in HIV-patients is highly variable and its association with antiretroviral therapy (ART) is controversial. OBJECTIVE: To estimate the prevalence of AH and associated factors in HIV-patients on ART. METHODS: This cross-sectional study was conducted in HIV-patients attended in a referral center in Salvador, Brazil. We evaluated clinical, socio-demographic and anthropometric data. Student's ttests or Mann-Whitney's and Pearson's chi-square tests were used to compare the groups. Values of p <0.05 were considered significant. The variables that presented a value of p <0.20 were included in a logistic regression model. RESULTS: We evaluated 196 patients (60.7% male) with a mean age of 46.8 ± 11.7 years and a mean body mass index of 24.9 ± 5.3 kg / m2. The median elapsed time since HIV diagnosis and ART use was 11.8 (4.4 - 18.1) and 7.2 (2.7 - 15.3) years, respectively. The prevalence of AH was 41.8%. For individuals > 50 years old, there was a significant association between the increased abdominal circumference and AH and patients ≤ 50 years old presented significant association between AH and overweight, increased abdominal circumference and number of previous ART regimens. After multivariate analysis, age [OR:1.085; 95% CI 1,039 - 1,133], overweight [OR: 4.205; 95% CI 1,841 - 9,606], family history of AH [OR: 2.938; 95% CI 1,253 - 6.885], increased abdominal circumference [OR: 2.774; 95% CI 1.116 - 6.897] and life-time number of ART regimens used [OR: 3.842; 95% CI 1.307 - 11.299] remained associated with AH. CONCLUSION: AH was highly prevalent and was associated not only with classical risk factors for arterial hypertension, but also with specific ART regimens.

Non-alcoholic fatty liver disease in patients infected with human immunodeficiency virus: a systematic review.

OBJECTIVE: To evaluate the prevalence of nonalcoholic fatty liver disease (NAFLD) in patients with HIV/AIDS. METHODS: The systematic review included articles indexed in MEDLINE (by PubMed), Web of Science, IBECS, and LILACS. Studies eligible included the year of publication, diagnose criteria of NAFLD and HIV, and were published in English, Portuguese, or Spanish from 2006 to 2018. The exclusion criteria were studies with HIV-infection patients and other liver diseases. Two reviewers were involved in the study and applied the same methodology, according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). RESULTS: One hundred and sixteen papers were selected, including full articles, editorial letters, and reviews. Twenty-seven articles were excluded because they did meet the inclusion criteria. A total of 89 articles were read, and 13 were considered eligible for this review. Four case series used imaging methods to identify NAFLD, and nine included histology. The prevalence of NAFLD in HIV-patients ranged from 30%-100% and, in nonalcoholic steatohepatitis (NASH), from 20% to 89%. A positive association between dyslipidemia, insulin resistance, and body mass index was observed. There was no agreement between the studies that evaluated the relationship between antiretroviral drugs and NAFLD. CONCLUSION: This systematic review showed a high prevalence of NAFLD in HIV-patients, which was associated with metabolic risk factors. The possible association between antiretroviral therapy and NAFLD needs further studies.

Metabolic Syndrome in HIV-patients in Antiretroviral Therapy.

INTRODUCTION: The global prevalence of metabolic syndrome (MS) among people living with HIV/AIDS varies from 20% to 33%. OBJECTIVE: to estimate the prevalence of metabolic syndrome and associated factors in a group of HIV-infected patients on antiretroviral therapy. METHODS: This is a cross-sectional study with HIV-infected patients from a reference center in Bahia, Brazil. We evaluated clinical, socio-demographic and anthropometric data. MS was defined according to the guidelines of International Diabetes Federation. RESULTS: We evaluated 152 patients with mean age of 47.3±11.6 years, 59.2% male. The main comorbidities detected were diabetes (3.3%) hypertriglyceridemia (9.3%) and metabolic syndrome (MS,38.2%). Patients with MS were predominantly women (55.2% vs 31.9%; p=0.005), older [52.1 (10.4) vs 44.3 (11.3); p<0.001], and had overweight (74.1% vs 23.4%; p<0.001). After multivariate analysis MS remained associated with age (OR = 1.076; 95% CI: 1.030 - 1.125), female sex (OR = 2.452; 95% CI: 1.114 - 5.374) and family history of hypertension (OR = 3.678; 95% CI: 1.431 - 9.395). CONCLUSION: Almost half of the HIV-infected patients in Bahia presents with MS which seems to be driven by classical risk factors.

Association Between Cardiovascular Risk Factors and 25(OH)D Levels in Obese Patients.

Background: Obesity is associated with lower levels of 25-hydroxyvitamin D [25(OH)D] and higher cardiovascular risk related to metabolic syndrome (MetS). Our purpose was to investigate if there is an association between levels of 25(OH)D and the components of MetS in an obese sample. Methods: This cross-sectional study enrolled obese patients referred for bariatric surgery in a specialized clinic. Secondary data were gathered as follows: glycemic and lipid profiles, 25(OH)D, anthropometric parameters, and clinical and sociodemographic information. The results were presented as means (standard deviations) or medians and interquartile intervals or absolute and relative frequencies. The patients were divided into three groups based on 25(OH)D terciles for analysis and were compared using ANOVA, Kruskal-Wallis or chi-squared tests. The correlations were calculated by Spearman's or Pearson's correlation tests. Results: We studied 299 patients, with the majority being women (74.9%). The patients' average (SD) age and 25(OH)D level were 36 (9) years and 25.8 (7.5) ng/mL, respectively. There was no association between vitamin D and MetS or its components. A progressive decrease in total cholesterol, low-density lipoprotein cholesterol (LDL-c), and nonhigh-density lipoprotein cholesterol (HDL-c) was observed as the serum vitamin D level increased, although only the latter reached statistical significance (P = 0.033). The correlation analysis showed a negative linear association between 25(OH)D and total cholesterol (r = -0.157; P = 0.047), 25(OH)D and LDL-c (r = -0.164; P = 0.038), and 25(OH)D and non-HDL-c (r = -0.176; P = 0.026). Conclusions: There was a negative correlation between 25(OH)D levels and the atherogenic profile but none with the MetS.
