Comparação entre o Disease Activity Score-28 e o Juvenile Arthritis Disease Activity Score na artrite idiopática juvenil

Introduction: the assessment of the activity of rheumatoid arthritis and juvenile idiopathic arthritis is made by means of different tools, respectively DAS-28 and JADAS.Objective: To compare DAS-28 and JADAS with scores of 71, 27 and 10 joint counts in juvenile idiopathic arthritis.Method: A secondary analysis of a phase III placebo-controlled trial, testing safety and efficacy of abatacept was conducted in 8 patients with 178 assessment visits. Joint count scores for active and limited joints, physician's and parents'global assessment by 0-10 cm Visual Analog Scale, and erythrocyte sedimentation rate normalized to 0-10 scale, in all visits. The comparison among the activity indices in different observations was made through Anova or adjusted gamma model. The paired observations between DAS-28 and JADAS 71, 27 and 10, respectively, were analyzed by linear regression.Results: There were significant differences among individual measures, except for ESR, in the first four months of biological treatment, when five of the eight patients reached ACR-Pedi 30, with improvement. The indices of DAS-28, JADAS 71, 27 and 10 also showed significant difference during follow-up. Linear regression adjusted model between DAS-28 and JADAS resulted in mathematical formulas for conversion: [DAS-28 = 0.0709 (JADAS 71) + 1.267] (R-2 = 0.49); [DAS-28 = 0.084 (JADAS 27) + 1.7404] (R-2 = 0.47) and [DAS-28 = 0.1129 (JADAS-10) + 1.5748] (R-2 = 0.50).Conclusion: The conversion of scores of DAS-28 and JADAS 71, 27 and 10 for this mathematical model would allow equivalent application of both in adolescents with arthritis.

Use of the probability of stone formation (PSF) score to assess stone forming risk and treatment response in a cohort of Brazilian stone formers

Introduction: The aim was to confirm that PSF (probability of stone formation) changed appropriately following medical therapy on recurrent stone formers.Materials and Methods: Data were collected on 26 Brazilian stone-formers. A baseline 24-hour urine collection was performed prior to treatment. Details of the medical treatment initiated for stone-disease were recorded. A PSF calculation was performed on the 24 hour urine sample using the 7 urinary parameters required: voided volume, oxalate, calcium, urate, pH, citrate and magnesium. A repeat 24-hour urine sample was performed for PSF calculation after treatment. Comparison was made between the PSF scores before and during treatment.Results: At baseline, 20 of the 26 patients (77%) had a high PSF score (> 0.5). Of the 26 patients, 17 (65%) showed an overall reduction in their PSF profiles with a medical treatment regimen. Eleven patients (42%) changed from a high risk (PSF > 0.5) to a low risk (PSF < 0.5) and 6 patients reduced their risk score but did not change risk category. Six (23%) patients remained in a high risk category (> 0.5) during both assessments.Conclusions: The PSF score reduced following medical treatment in the majority of patients in this cohort.

Gestational protein malnutrition impairs c-myc and p63 protein expression, increases prostatic intraepithelial neoplasia incidence and prostatitis aggressiveness in adult male offspring subjected to hormonal handling

Background: Prostate cancer is the second most common cancer diagnosed in men; however its etiology remains unknown. Previous studies have shown that environmental adverse factors, such as maternal nutritional status during pregnancy, can influence fetal development and predispose people to diseases in adult life. The feeding of low-protein diets to pregnant rats result in fetal growth disturbance, androgen/estrogen unbalance and changes in the expression and sensibility of hormone receptors in male offspring. These alterations can promote permanent changes in androgen dependent organs, such as in the prostate. In this sense, we hypothesized that the hormonal unbalance that occurs during aging can lead to an increase in the susceptibility to prostatic disorders. Aim: To evaluate our hypothesis, malnourished male rat offspring were submitted to simultaneous estrogen and testosterone exposure in adulthood, to drive lesions in the rat ventral prostate gland (VP). Methods: 17 week-old Wistar rats (n=48) that received in utero normal protein diet (NP group, AIN93G=17% protein) or low protein diet (RP group, AIN93G modified=6% protein) were given implants with 17β-estradiol plus testosterone administration (NPH and RPH groups) for 17 weeks. The animals were killed at the age of 34 weeks and the VP were excised, weighted and processed for histopathological, immunohistochemical (Ki67, AR, p63, e-caderin, laminin, c-myc and GSTP), biochemical and ultrastructural analysis. Results: Both absolute and relative VP weight from NPH animals were about 30% higher than RPH. Serological data showed that estradiol levels were similar in both groups, but testosterone levels were lower in the RPH male offspring. The steroid hormone exposure in adult life promoted prostate lesions in both RPH and NPH offspring associated with reactive stroma. VP from RPH group exhibited heightened susceptibility to prostatic intraepithelial neoplasia (mainly cribriform and signet ring-cell patterns) and increased the incidence and aggressiveness of prostatitis. In this group, a higher proportion of basal cells, increased proliferation index, lower expression ofthe androgen receptor and increased focus of collagenous micronodules closely associated to epithelial neoplasias were also observed. Conclusion:These observations suggest that maternal protein restriction alters adult prostate response to androgen/estrogen handling and increases susceptibility to prostate diseases.

Circulating thyroid hormone levels in young pregnant rats and their fetuses: Effect of malnutrition

In order to evaluate some factors likely to be involved in the maternal and fetal growth impairment due to alimentary protein deficiency, the circulating levels of triiodothyronine (T 3) and thyroxine (T 4) were studied in 4 young (45-day-old) female rat groups: control and malnourished, both nonpregnant and pregnant; similarly schedules groups were studied using adult (100-day-old) rats. Circulating levels of T 4 were higher in nonpregnant, malnourished young rats in their corresponding controls. T 3 levels were higher in young malnourished animals and lower in adult malnourished animals, nonpregnant or pregnant, as compared to controls. Pups from young malnourished mothers showed significantly lower birth weights than those from controls. The present results suggest that there are age differences in thyroid function, as affected by protein-calorie malnutrition in pregnant and non-pregnant rats. On the other hand, the circulating thyroid hormone levels were not importantly affected by the mother dietary protein restriction under our experimental conditions.

Protein-energy malnutrition as a consequence of the hospitalization of gastroenterologic patients

The effects of the clinical and dietetics in patient managements on the protein-energy status of hospitalized patients were retrospectively (four yr) investigated in 243 adult (49 +/- 16 yr), male (168) and female (75) patients suffering from chronic liver diseases (42%), intestinal diseases with diarrhea (14%), digestive cancers (11%), chronic pancreatitis (10%), stomach and duodenum diseases (7%), acute pancreatitis (7%), primary protein-energy malnutrition (3%), esophagus diseases (3%), intestinal diseases with constipation 14 (2%) and chronic alcoholism (2%). The protein-energy nutritional status assessed by combinations of anthropometric and blood parameters showed 75% of protein energy malnutrition at the hospital entry mostly (4/5) in severe and moderate grades. The overall average of hospitalization was 20 +/- 15 days being the shortest (13 +/- 5,7 days) for esophagus diseases and the longest (28 +/- 21 days) for the intestinal diseases with diarrhea patients which also received mostly (42%) of the enteral and/or parenteral feedings followed by acute pacreatitis (41%) and digestive cancers (31%) patients. When compared to the entry the protein-energy malnutrition rate at the discharge decreased only 5% despite the increasing of 30% found on the protein-energy intake. The main improvement of the protein-energy nutritional status were attained to those patients showing protein-energy malnutrition milder degrees at the entry which belonged mostly to primary protein-energy malnutrition, acute pancreatitis and intestinal diseases with diarrhea diseases. The later two groups showed protein-energy nutritional status improvement only after the second week of hospitalization. The digestive cancers patients had their protein-energy nutritional status worsened throughout the hospitalization whereas it happened only in the first week for the intestinal diseases with diarrhea and chronic liver diseases patients, improving thereafter up to the discharge. The protein-energy nutritional status improvement found in few patients could be attributed to some complementary factors such as theirs mild degree of protein-energy malnutrition at entry and/or non-invasive propedeutics and/or enteral-parenteral feddings and/or longer hospitalization staying. The institutional causes for the unexpected lack of nutritional responses by the patients were probably the high demand for the few available beds which favour the hospitalization of the most severed patients and the university-teaching pressure for the high rotation of the available beds. Both often resulting in early discharging. In persisting the current physical area and attendance demand one could suggest an aggressive support early at the entry preceding and/or accompanying the more invasive propedeutical procedures.

The relationship between inflammation, dyslipidemia and physical exercise: from the epidemiological to molecular approach

Dyslipidemia and inflammation are frequently found in some diseases, such as obesity, type 2 diabetes mellitus, and cancer cachexia. Recent literature has identified that lipids have a pivotal role in the activation of inflammatory pathways, increasing the production of inflammatory cytokines, mainly tumor necrosis factor alpha, interleukin 6 and 1β. On the other hand, cytokines can promote disruption of lipid metabolism, in special cholesterol reverse transport, which is linked to development of atherosclerosis. With this in mind, acute and chronic exercise trainings have been pointed as important tools to counteract both dyslipidemia symptoms and systemic inflammation. Moreover, physical activity has been recommended in the prevention/treatment of the above mentioned outcomes by important health organizations around the world, mainly because it costs less and generates fewer side effects than isolated medicine. Despite the well-documented capacity of acute and chronic exercise training to counteract sustained disease-related immunometabolism, we have chosen to take a look from a current perspective in molecular pathways and in the field of epidemiology. The aim of the present review was therefore to discuss the results of dyslipidemia and inflammatory conditions with acute and chronic exercise training, which underlies the field of molecular pathways and epidemiology. The mechanisms underlying the response to the treatment are considered.

The glasgow prognostic score. An useful tool to predict survival in patients with advanced esophageal squamous cell carcinoma

To evaluate the usefulness of the Glasgow Prognostic Score (GPS) in patients with esophageal carcinoma (EC). A total of 50 patients with EC were analyzed for GPS, nutritional and clinicopathologic parameters. Patients with CRP ≤ 1.0mg/L and albumin ≥ 3.5mg/L were considered as GPS=0. Patients with only CRP increased or albumin decreased were classified as GPS=1 and patients with CRP > 1.0mg/L and albumin < 3.5mg/L were considered as GPS=2. GPS of 0, 1 and 2 were observed in seven, 23 and 20 patients, respectively. A significant inverse relationship was observed between GPS scores and the survival rate. The survival rate was greatest in patients with GPS= 0 and significantly higher than those from patients with GPS=1 and GPS=2. Minimum 12-month survival was observed in 71% patients with GPS=0 and in 30% patients with GPS=1. None of the patients with GPS=2 survived for 12 months. A significant relationship between CRP or albumin individually and the survival rate was observed. No significant relationship among nutritional, clinic pathological parameters and survival was found. Glasgow Prognostic Score is an useful tool to predict survival in patients with esophageal carcinoma.

Inhibition of diethylnitrosamine-initiated alcohol-promoted hepatic inflammation and precancerous lesions by flavonoid luteolin is associated with increased sirtuin 1 activity in mice

Chronic and excessive alcohol consumption is an established risk for hepatic inflammation and carcinogenesis. Luteolin is one of the most common flavonoids present in plants and has potential beneficial effects against cancer. In this study, we examined the effect and potential mechanisms of luteolin supplementation in a carcinogen initiated alcohol-promoted pre-neoplastic liver lesion mouse model. C57BL/6 mice were injected with diethylnitrosamine (DEN) [i.p. 25 mg/kg of body weight (BW)] at 14 days of age. At 8 weeks of age mice were group pair-fed with Lieber-DeCarli liquid control diet or alcoholic diet [ethanol (EtOH) diet, 27% total energy from ethanol] and supplemented with a dose of 30 mg luteolin/kg BW per day for 21 days. DEN-injected mice fed EtOH diet displayed a significant induction of pre-neoplastic lesions, a marker associated with presence of steatosis and inflammation. Dietary luteolin significantly reduced the severity and incidence of hepatic inflammatory foci and steatosis in DEN-injected mice fed EtOH diet, as well the presence of preneoplastic lesions. There was no difference on hepatic protein levels of sirtuin 1 (SIRT1) among all groups; however, luteolin supplementation significantly reversed alcohol-reduced SIRT1 activity assessed by the ratio of acetylated and total forkhead box protein O1 (FoXO1) and SIRT1 target proliferator-activated receptor gamma, coactivator 1 alpha (PGC1α). Dietary intake of luteolin prevents alcohol promoted pre-neoplastic lesions, potentially mediated by SIRT1 signaling pathway.
