title: The Relationship between Uric Acid/Albumin Ratio and Carotid Intima-Media Thickness in Patients with Hypertension

description: Abstract Background Hypertension causes subendothelial inflammation and dysfunction in resulting atherosclerosis. Carotid intima-media thickness (CIMT) is a useful marker of endothelial dysfunction and atherosclerosis. The uric acid to albumin ratio (UAR) has emerged as a novel marker for predicting cardiovascular events. Objective We aimed to investigate the association of UAR with CIMT in hypertensive patients. Methods Two hundred sixteen consecutive hypertensive patients were enrolled in this prospective study. All patients underwent carotid ultrasonography to classify low (CIMT &lt; 0.9 mm) and high (CIMT ≥ 0.9 mm) CIMT groups. The predictive ability of UAR for high CIMT was compared with systemic immune inflammation index (SII), neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and C-reactive protein/albumin ratio (CAR). A two-sided p-value &lt;0.05 was accepted as statistically significant. Results Patients with high CIMT were older and had higher UAR, SII, NLR, and CAR than low CIMT. Age, UAR, SII, NLR, and CAR, but not PLR, were associated with high CIMT. In multivariable analysis, age, CRP, SII, and UAR were independent predictors of high CIMT. The discrimination ability of UAR was higher than uric acid, albumin, SII, NLR, and CAR, and UAR had a higher model fit than those variables. UAR had higher additive improvement in detecting high CIMT than other variables, as assessed with net-reclassification improvement, IDI, and C-statistics. UAR was also significantly correlated with CIMT. Conclusion UAR might be used to predict high CIMT and might be useful for risk stratification in hypertensive patients.

title: A case of colonoscopy-induced Wunderlich's syndrome in a hemodialysis patient: coincidence or association?

description: Abstract Wunderlich syndrome, or spontaneous renal hemorrhage (SRH), is a rare condition encountered in patients undergoing chronic hemodialysis (HD) usually attributed to acquired cystic kidney disease (ACKD) among other causes. In the literature, colonoscopy is associated with splenic injuries, and renal hemorrhage has not been previously described. Management can range from conservative treatment to angiographic embolization or exploration and nephrectomy. Here we report an unusual case of a 54-year-old woman HD patient who presented with SRH within a few days of colonoscopy. The reason of SRH was rupture of an ACKD cyst. We assumed that colonoscopy was a provoking factor and elaborated hypotheses for its etiopathogenesis. The patient underwent successful left nephrectomy. The importance of this case lies in the fact that colonoscopy is not always an innocent procedure in HD patients, and could be complicated by renal cyst hemorrhage.

title: Decreased Serum Levels of Soluble Oncostatin M Receptor (sOSMR) and Glycoprotein 130 (sgp130) in Patients with Coronary Artery Disease

description: Abstract Background Oncostatin M (OSM) is a pleiotropic cytokine which, after arterial injury, has proven to be to be rapidly expressed. Objectives To correlate the serum levels of OSM, soluble OSM receptor (sOSMR), and soluble fraction of glycoprotein 130 (sgp130) in patients with coronary artery disease (CAD) with clinical parameters. Methods Levels of sOSMR and sgp130 were evaluated by ELISA and OSM by Western Blot, in patients with CCS (n=100), patients with ACS (n=70), and 64 control volunteers without clinical manifestations of the disease. P-values &lt; 0.05 were considered to be statistically significant. Results CAD patients exhibited significantly lower levels of sOSMR and sgp130 and higher levels of OSM when compared to the controls (both p &lt; 0.0001). Clinical analysis displayed, lower levels of sOSMR in men ([OR] = 2.05, p = 0.026), youth (OR = 1.68, p = 0.0272), hypertensives (OR = 2.19, p = 0.041), smokers (OR = 2.19, p = 0.017), patients that did not present dyslipidemia (OR = 2.32, p = 0.013), patients with Acute Myocardial Infarction [AMI] (OR = 3.01, p = 0.001) and patients not treated with statin (OR = 1.95, p = 0.031), antiplatelet agent (OR = 2.46, p = 0.005), inhibitors of calcium channels (OR = 3.15, p = 0.028), and antidiabetic drugs (OR = 2.97, p = 0.005). The levels of sOSMR were also correlated with gender, age, hypertension, and use of medications in multivariate analysis. Conclusions Our data suggest that the enhanced serum levels of OSM, and decreased levels of sOSMR and sGP130 in patients with cardiac injury may play an important role in the pathophysiological mechanism of the disease. Furthermore, lower levels of sOSMR were associated with gender, age, hypertension, and the use of medications.

title: Predictors of long length of hospital stay among elders admitted with seizures in a tertiary centre: a prospective study

description: ABSTRACT Population ageing is a global phenomenon, and life expectancy in Brazil is growing fast. Epilepsy is the third most important chronic neurological disorder, and its incidence is higher among elderly patients than in any other segment of the population. The prevalence of epilepsy is greater among inpatients than in the general population and it is related to long length of hospital stay (LOS), which is associated with hospital mortality and higher healthcare costs. Despite these facts, reports of elderly inpatients admitted with seizures and associated outcomes are scarce. Objective: To identify predictors of long LOS among elderly inpatients admitted with seizures. Methods: We prospectively enrolled elders admitted with epileptic seizures or who experienced seizures throughout hospitalization between November 2015 and August 2019. We analysed demographic data, neurological disorders, clinical comorbidities, and seizure features to identify risk factors. Results: The median LOS was 11 days, with an interquartile range (IQR) of 5-21 days. The frequency of long LOS (defined as a period of hospitalization ≥12 days) was 47%. Multivariate analysis showed there was an exponential increase in long LOS if a patient showed any of the following conditions: intensive care unit (ICU) admission (OR=4.562), urinary tract infection (OR=3.402), movement disorder (OR=5.656), early seizure recurrence (OR=2.090), and sepsis (OR=4.014). Conclusion: Long LOS was common among elderly patients admitted with seizures, and most predictors of long LOS found in this cohort might be avoidable; these findings should be confirmed with further research.

title: Development and psychometric properties of the Cognitive Distortions Questionnaire for Adolescents (CD-Quest-T)

description: Abstract Introduction The Cognitive Distortions Questionnaire (CD-Quest) is an instrument that identifies logical errors or cognitive distortions and is used in trial-based cognitive therapy (TBCT). However, it had previously only been available for adults. Objectives To develop and validate a version of the CD-Quest for teens (CD-Quest-T) aged 11 to 17 years and test its psychometric properties. Method A total of 299 schoolchildren participated in the investigation. After content validity was assessed, the language was adapted for the target age group, and the length of the instrument was reduced to eight items (from the initial 15). Five cognitive therapists analyzed the content and structure of the items. Finally, to investigate the construct validity of the CD-Quest-T, the instrument was divided into a full scale and two subscales, which measure the frequency of the distortions and the intensity attributed to them, respectively. Results The overall internal consistency of the scale was α = 0.77, whereas subscale indices were α = 0.75 for the frequency scale and α = 0.73 for the intensity scale. Results from exploratory factor analysis and concurrent validity analysis indicated that the CD-Quest-T items have good psychometric properties and generate scores reliably. Conclusion The psychometric properties of the CD-Quest-T demonstrate its adequacy for measurement of cognitive distortions in adolescents.

title: Membranoproliferative glomerulonephritis: current histopathological classification, clinical profile, and kidney outcomes

description: Abstract Introduction: Membranoproliferative glomerulonephritis (MPGN) is a rare glomerular disease with a variable prognosis. A new classification based on the presence or absence of immunoglobulins and complement deposits in immunofluorescence microscopy (IF) of kidney biopsy has recently been proposed. The objectives of the study were to determine and compare the clinical, laboratory, and histopathological characteristics of those with primary or secondary MPGN, reclassify the primary ones based on IF findings, and evaluate kidney outcomes. Methods: This was an observational retrospective cohort study carried out in a single center (UNIFESP), based on the data collected from medical records of patients followed from 1996 to 2019. Results: Of 53 cases of MPGN, 36 (67.9%) were classified as primary and 17 (32.1%) as secondary MPGN. Most patients were hypertensive (84.9%) and had edema (88.7%) and anemia (84.9%); 33 (91.7%) patients classified as primary MPGN were reclassified as immune-complex-mediated and 3 (8.3%) as complement-mediated. The secondary MPGN group had hematuria more frequently (p &lt;0.001) and a higher prevalence of deposits of IgG (p = 0.02) and C1q (p = 0.003). Regarding the outcome, 39% of the patients achieved partial or complete remission. Lower initial serum albumin and higher initial 24-hour proteinuria were factors associated with worst renal prognosis. Conclusions: According to the new histological classification, the vast majority of MPGN cases were classified as being mediated by immune complexes. There were few differences between primary and secondary MPGN in relation to their clinical and laboratory characteristics.

title: SOIL COVER IS STRATEGIC TO REMEDY EROSION IN SANDY SOILS

description: ABSTRACT Sandy-textured soils are naturally more vulnerable to the erosion process and their exploitation, although possible, is often performed inappropriately, favoring its degradation. In this context, this study aimed to classify the rainfall erosivity in a region of sandy soils to identify critical situations of soil and water loss and also correlate it with rainfall data to assess whether there is temporal dependence of this variable using geostatistical techniques. The potential for alternative and sustainable production systems to be used in regions with sandy soils was also analyzed. Historical data of precipitation in the study region were analyzed to determine the average monthly and annual erosivity indices, which were classified and its temporal dependence was assessed by applying geostatistics. NDVI data from satellite images were used to investigate the soil cover pattern in different production systems. Geostatistics was adequate for the analysis of rainfall erosivity, which showed moderate to strong temporal dependence. It was classified between strong and very strong and was highly dependent on precipitation, with events of higher erosion potential between October and March in the studied region. The vicious circle of degradation of sandy soils, such as those of the Bolsão region of Mato Grosso do Sul, Brazil, can be modified by adopting alternative and sustainable production systems that value the maximization of soil cover.

title: Translation and cross-cultural adaptation to Brazilian Portuguese of two brief screening tools for youth at risk of psychosis: the Prodromal Questionnaire (PQ-16) and the PRIME-Screen

description: Abstract Introduction Prodromal characteristics of psychosis have been described for more than a century. Over the last three decades, a variety of studies have proposed methods to prospectively identify individuals (and youth in particular) who are at high risk of developing a psychotic disorder. These studies have validated various screening instruments and made them available in several languages. Here, we describe the translation into Brazilian Portuguese and cross-cultural adaptation of two such screening tools – the Prodromal Questionnaire-16 (PQ-16) and the Prevention through Risk Identification, Management, and Education (PRIME)-Screen. Method Two bilingual native speakers of Brazilian Portuguese translated the questionnaires from English. A native English speaker then performed back-translations into English. These back-translated versions were submitted to the original authors. They provided feedback and later approved the final versions. Results After translation and cross-cultural adaptation, no items needed to be changed in the adapted PQ-16 and four items were revised in the PRIME-Screen. After the peer-review process, we included two suggestions in the PQ-16 to facilitate use of the tool in our cultural and social contexts. The PRIME-Screen did not need further changes. Conclusion These new instruments can help screen Brazilian Portuguese-speaking patients who are at risk of psychosis in primary care.
