Feeding characteristics and growth among children with prenatal exposure to Zika virus with and without microcephaly in the microcephaly epidemic research group pediatric cohort.

OBJECTIVE: To describe the feeding characteristics and growth of children with prenatal exposure to Zika virus (ZIKV) from birth to 48 months. DESIGN: Using data from the prospective Microcephaly Epidemic Research Group Pediatric Cohort (MERG-PC), children without microcephaly born to mothers with evidence of ZIKV infection during pregnancy (ZIKV-exposed children without microcephaly) and children with Zika-related microcephaly were compared using repeated cross-sectional analyses within the following age strata: birth; 1 to 12; 13 to 24; 25 to 36; and 37 to 48 months. The groups were compared in relation to prematurity, birth weight, breastfeeding, alternative feeding routes, dysphagia and anthropometric profiles based on the World Health Organization Anthro z-scores (weight-length/height, weight-age, length/height-age and BMI-age). RESULTS: The first assessment included 248 children, 77 (31.05%) with microcephaly and 171 (68.95%) without microcephaly. The final assessment was performed on 86 children. Prematurity was 2.35 times higher and low birth weight was 3.49 times higher in children with microcephaly. The frequency of breastfeeding was high (> 80%) in both groups. On discharge from the maternity hospital, the frequency of children requiring alternative feeding route in both groups was less than 5%. After 12 months of age, children with microcephaly required alternative feeding route more often than children without microcephaly. In children with microcephaly, the z-score of all growth indicators was lower than in children without microcephaly. CONCLUSIONS: Children with Zika-related microcephaly were more frequently premature and low birth weight and remained with nutritional parameters, i.e., weight-for-age, weight-for-length/height and length/height-for-age below those of the children without microcephaly.

Is low phase angle a risk indicator for frailty and pre-frailty among community-dwelling older adults?

Studies investigating the association between the phase angle (PA) and frailty are scarce. The PA is considered a practical, low-cost, noninvasive measure for the early identification of this clinical condition. To investigate the association between PA and frailty/pre-frailty, nutritional and clinical aspects in older people. A cross-sectional study was conducted with 51 older people (≥ 60 years). PA was determined using bioelectrical impedance analysis. Frailty profile was determined using the criteria of unintentional weight loss, self-reported fatigue, slow gait speed, low grip strength and insufficient physical activity. Nutritional status was evaluated based on the body mass index and appendicular skeletal muscle mass index (ASMMI). Sarcopenia and sarcopenic obesity were also investigated. Sociodemographic data were collected through interviews. Prevalence of frailty/pre-frailty was 84.3%, with no difference between the sexes. The first tercile of the sample had a PA lower than 6º, which was considered low. No significant difference in PA was found between older people with or without frailty/pre-frailty. In the multiple linear regression analysis, age and ASMMI were shown to be potential independent predictors for PA. Age showed an inverse correlation with PA, while ASMMI showed a direct correlation. No association was found between PA and frailty or pre-frailty.

25-hydroxyvitamin D insufficiency and inflammation increase cardiovascular risk in older people.

PURPOSE: The objective of this study was to identify an association between serum levels of 25(OH) D, inflammation and cardiovascular disease risk in older adults. METHODS: This was a cross-sectional study, with older adults of both sexes, investigating variables on lifestyle, anthropometric assessments (weight, height, waist circumference, BMI), and systemic arterial hypertension (systolic blood pressure, SBP, and diastolic blood pressure DBP), serum levels of 25(OH)D, serum high-sensitive C-reactive protein (hs-CRP), serum lipid profile and fasting blood glucose. Cardiovascular disease risk was assessed using the global risk score for cardiovascular events, the Framingham criteria. RESULTS: The sample consisted of 124 participants, 50.8% of whom were at high risk for cardiovascular events. Older adults with 25(OH)D insufficiency presented higher levels of blood sugar (p < 0.01), LDL-c (p = 0.03) SBP (p < 0.01) and hs-CRP (p < 0.01). When grouped by serum concentrations hs-CRP, it was observed that higher hs-CRP levels were associated with higher blood glucose (p = 0.02), SBP (p = 0.04) and lower HDL-c concentrations (p = 0.02). It was also observed that 25(OH)D insufficiency increased the chance of a high risk for cardiovascular events by 2.8 times (OR = 2.80; p = 0.01), which with high hs-CRP concentrations increased to 4.75 times (OR = 4.75; p < 0.01). CONCLUSION: Low concentrations of 25(OH)D and the presence of inflammation in older adults are associated with a high risk for cardiovascular diseases.

Characterization of amputees at a large hospital in Recife, PE, Brazil.

BACKGROUND: Limb amputation can be defined as a procedure that consists of separating a limb or a segment of a limb from the body. OBJECTIVES: To describe the profile of limb amputation procedures performed at a large hospital run by the state of Pernambuco (Brazil). METHODS: Cross-sectional descriptive and retrospective study conducted at a large hospital in the city of Recife, PE. Data were collected from the records of patients who underwent amputations during 2017. Records from patients who had had a limb amputation during 2017 were included, unless data were illegible or missing. RESULTS: A total of 328 procedures were performed on 274 patients, the majority of whom were male (57.7%). There was a predominance of lower limb amputations (64.2%), of non-traumatic causes (86.5%), and urgent treatment (96.4%). The majority of patients who underwent amputations remained in hospital for 11 to 25 days (32.1%). The study found that the majority of amputees were discharged (69.7%), although a proportion died. Deaths of lower limb amputees were primarily among elderly women in the age range of 60 to 90 years (76%), females (55%), and patients subjected to a single amputation (91%). CONCLUSIONS: The data observed in this study are alarming, particularly considering that many of these amputations could have been avoided, since they were caused by complications of diseases that can be prevented and controlled at healthcare services of a lower level of complexity and at a relatively low cost.

Prognostic value of hematological parameters in patients with acute myocardial infarction: Intrahospital outcomes.

BACKGROUND: The intensity of the inflammatory response and hemodynamic repercussion in acute myocardial infarction causing the presence in the peripheral circulation of nucleated red blood cells (NRBCs), increases in mean platelet volume (MPV) and neutrophil to lymphocyte ratio (NLR) are associated with a poorer prognosis. The aim of this study was to assess the role of these hematological biomarkers as predictors of all causes of mortality during the hospitalization of patients with acute myocardial infarction. METHODS: Nucleated red blood cells, mean platelet volume and neutrophil to lymphocyte ratio were measured daily during the hospitalization of the patients with acute myocardial infarction. We excluded patients younger than 18 years, on glucocorticoid therapy, with cancer or hematological diseases and those that were readmitted after hospital discharge. We performed a multiple logistic analysis to identify independent predictors of mortality. RESULTS: We included 466 patients (mean age 64.2 ± 12.8 years, 61.6% male). The prevalence of NRBCs in the sample was 9.1% (42 patients), with levels > 200/µL in 27 patients (5.8%). The mean MPV value was 10.9 ±0,9 and the mean NLR value was 3.71 (2,38; 5,72). In a multivariate analysis of serum NRBCs (HR 2.42, 95% CI: 1.35-4.36, p = 0.003), MPV (HR 2.97, 95% CI: 1.15-7.67, p = 0.024) and NLR (HR 5.02, 95% CI: 1.68-15.0, p = 0.004). The presence in the peripheral blood of NRBCs, increased in mean platelet volume and neutrophil to lymphocyte ratio were associated with higher mortality. CONCLUSIONS: Nucleated red blood cells, mean platelet volume and neutrophil to lymphocyte ratio are independent predictors of intrahospital mortality. Therefore, an important tool in intrahospital clinical surveillance.

Effectiveness of a Behavior Change Program on Physical Activity and Eating Habits in Patients With Hypertension: A Randomized Controlled Trial.

BACKGROUND: This study aimed to analyze the effect of a behavior change program, called Vida Ativa Melhorando a Saúde (VAMOS), on physical activity, eating habits, and quality of life in patients with hypertension. METHODS: A randomized controlled trial was carried out in 90 patients with hypertension (57.8 ± 9.9 y). They were randomly assigned to 2 groups: VAMOS group (n = 45) and control group (n = 45). The VAMOS group participated in a behavioral change program aimed at motivating changes in physical activity and nutrition behavior for 12 weeks. Physical activity, eating habits, quality of life, self-efficacy, and social support were evaluated at preintervention and postintervention. RESULTS: The control group increased sedentary time (407 ± 87 vs 303 ± 100 min/d; P < .05) and sedentary bouts (434 ± 86 vs 336 ± 98 min/d; P < .05) and reduced total physical activity (553 ± 87 vs 526 ± 86 min/d; P < .05). The VAMOS group improved the general healthy eating habits score (36.9 ± 6.6 vs 43.4 ± 5.8; P < .05) and quality of life (44% vs 92%; P < .05). CONCLUSION: The VAMOS program was effective in improving eating habits and quality of life in patients with hypertension.

Association Between Nutritional Status, Inflammatory Condition, and Prognostic Indexes with Postoperative Complications and Clinical Outcome of Patients with Gastrointestinal Neoplasia.

The aim of this study is to describe and relate nutritional and inflammatory status and prognostic indexes with postoperative complications and clinical outcome of patients with gastrointestinal malignancies. Twenty-nine patients were evaluated; nutritional assessment was carried out by subjective and objective parameters; albumin, pre-albumin, C-reactive protein (CRP), and alpha-1-acid glycoprotein (AGP) were determined. To assess prognosis, the Glasgow scale, the Prognostic Inflammatory Nutritional Index (PINI), and CRP/albumin ratio were used; the clinical outcomes considered were hospital discharge and death. A high Subjective Global Assessment (SGA) score was associated with the occurrence of postoperative complications: 73% of the patients with postoperative complications had the highest SGA score, but only 6% of those without postoperative complications had the highest SGA score (P < 0.001). Greater occurrence of death was observed in patients with a high SGA score, low serum albumin, increased CRP, PINI > 1, and Glasgow score 2. There was a positive correlation between weight loss percentage with serum CRP levels (P = 0.002), CRP/albumin (P = 0.002), PINI (P = 0.002), and Glasgow score (P = 0.000). This study provides evidence that the assessment of the nutritional status and the use of prognostic indexes are good tools for predicting postoperative complications and clinical outcome in patients with gastrointestinal neoplasia.

Effect of diethylcarbamazine on chronic hepatic inflammation induced by alcohol in C57BL/6 mice.

Some pharmacological studies showed that diethylcarbamazine (DEC) interferes with the arachidonic acid metabolism, acting as an anti-inflammatory drug. The chronic alcohol consumption activates the hepatic inflammatory response associated to T-cell activation and overproduction of pro-inflammatory cytokines. The present work analyzed the anti-inflammatory effect of DEC on hepatic cells of alcoholic mice. Thirty-two male C57BL/6 mice were equally divided in the following groups: (a) control group (C), which received only water, (b) DEC-treated group, which received 50 mg/kg for 12 day (DEC50), (c) the alcoholic group (EtOH), submitted to only alcohol and (d) the alcohol-DEC treated group (EtOH50), submitted to alcohol plus DEC treatment after the induction of chronic alcoholism for 5 weeks. Biochemical analyses were performed and liver fragments were processed for light microscopy, transmission electron microscopy, immunohistochemical and western blot. The level of AST increased significantly in alcoholic group whereas a significant reduction of serum AST was detected in the EtOH50 group. Histological and ultrastructural analysis of alcoholic group showed evident hepatocellular damage, which was strikingly reduced in the alcoholic DEC-treated group. Immunohistochemistry results revealed highly expression of inflammatory markers as MDA, NF-κB, TNF-α, IL-6, VCAM and ICAM by the hepatic cells of the EtOH group; however no immunoreactivity for any of these cytokines was detected after DEC treatment. Western blot analyses showed increased MCP-1 and iNOS expression in EtOH group, which was significantly inhibited by DEC treatment. According to the present results, DEC can be a potential drug for the treatment of chronic inflammation induced by chronic alcoholism.

Effect of maternal diet rich in omega-6 and omega-9 fatty acids on the liver of LDL receptor-deficient mouse offspring.

BACKGROUND: Omega-6 fatty acids are important to fetal development. However, during gestation/lactation, these fatty acids may contribute toward the development of fat tissue. Omega-9 fatty acids are associated with a reduction in serum lipids and protection from liver disease. OBJECTIVES: The present study investigated the effect of the maternal intake of omega-6 and omega-9 in hypercholesterolemic mothers on the liver of the offspring. METHODS: LDL receptor-deficient mice were fed a diet rich in either omega-6 (E6D) or omega-9 (E9D) for 45 days prior to mating and until the birth of the offspring, evaluating the effect on the offspring liver in comparison to a standard diet (STD). RESULTS: Mothers fed with the E6D experienced an increase in total cholesterol (TC) and the offspring exhibited an increase in TC, hepatic triglycerides (TG), and CC-chemokine ligand (CCL)2/monocyte chemoattractant protein (MCP)-1 as well as a reduction in HDL. Histological analysis on this group revealed steatosis, leukocyte infiltrate, and increased CCL2/MCP-1 expression. The ultrastructural analysis revealed hepatocytes with lipid droplets and myofibroblasts. The offspring of mothers fed the standard diet exhibited low serum TC, but microvesicular steatosis was observed. The offspring of mothers fed the E9D exhibited lower serum and hepatic TG as well as higher LDL in comparison to the other diets. The histological analyses revealed lower steatosis and leukocyte infiltrate. CONCLUSIONS: The findings suggest that hypercholesterolemic mothers with a diet rich in omega-6 fatty acids predispose their offspring to steatohepatitis, whereas a diet rich in omega-9 has a protective effect.
