title: Association between disease activity and quality of life among patients with rheumatoid arthritis

description: Abstract The aim of this study is the association between the scores of disease activity, functional capacity and quality of life among patients diagnosed with rheumatoid arthritis, under clinical treatment at the Regional University Hospital of Campos Gerais - Wallace Thadeu de Mello and Silva. The sample was composed by volunteer patients, who freely underwent 3 research questionnaires. With the results of the survey, the disease activity score was correlated to the functional capacity and the quality-of-life scores. A mean of 3.87 and 1.2 was observed for the disease activity and the functional capacity scores, respectively, yet not achieving a correlation between those two variables. A strong correlation between the disease activity and the “functional capacity”, “general health status” and “mental health” domains was found. The lowest average observed corresponded to “physical limitation”, from the quality-of-life questionnaire. There was no statistically significant correlation between disease activity and functional capacity, although disease activity seems to affect the mental health, general health status and functional capacity of patients.

title: Motor and respiratory functions are main challenges to patients with multiple sclerosis

description: Abstract Introduction People with multiple sclerosis (MS) present wide and varied symptoms. Objective To investigate the impact of MS on subjects’ motor and respiratory functions. Methods One hundred one participants were enrolled in this study. The subjects had previous diagnosis of relapsing-remittent MS (n = 48) or presented no neurologic diseases (n = 53, control group). Assess-ments involved mobility (Timed Get Up and Go) and balance (Berg Balance Scale) tests. A force platform was used to evaluate postural stabilometry. Respiratory functions were assessed with a portable spirometer and a digital manovacuometer. Data analyses were carried out with Student´s t-tests, chi-square, and Pearson correlation index. Significance was set at 5%. Results Compared to control peers, participants with MS showed higher motor dysfunctions affecting mobility, balance, and postural stability. Spirometry indicated normal parameters for pulmonary flows and lung capacities in both groups. The manovacuometer, differently, pointed to a respiratory muscle weakness in 48% of participants with MS. Correlation analyses highlighted that respiratory functions are more associated to dynamic than to static motor tests. Conclusion Pathological changes in MS lead to motor dysfunction on mobility, balance and postural stability. Respiratory tests showed normal pulmonary flows and lung capacities in patients with MS, but with commitment of respiratory muscle strength. Respiratory functions were more impacted by dynamic tasks rather than static motor tasks.

title: Pediatric kidney transplant and cardiometabolic risk: a cohort study

description: Abstract Introduction: Patients with chronic kidney disease (CKD) are known to have increased cardiovascular risk but there are few data on the risk of pediatric kidney transplant recipients. We aimed to assess the impact of pre- and post-transplant overweight on allograft function and to characterize the evolution of several cardiovascular risk variables over time and their impact. Methods: A retrospective analysis of the records of 23 children/adolescents followed at a tertiary center after kidney transplant was conducted. Data on anthropometry and cardiometabolic variables were analyzed before transplant, six and 12 months after the transplant, and at the last follow-up visit. The impact of the variables on allograft function (glomerular filtration rate (GFR)) was estimated by creatinine-based revised Schwartz formula (Cr-eGFR) and was evaluated using nonparametric tests. Results: The 23 patients included in the study had a median age of 6.3 (4.4-10.1) years. Both systolic and diastolic BP z-score values significantly decreased between BMI groups [1.2 (-0.2 - 2.3) vs. 0.3 (-0.4 - 0.6), p=0.027 and 0.8 (-0.4 - 1.3) vs. 0.1 (-0.6 - 0.7), p=0.028, pre-transplant and at the final evaluation, respectively]. During follow-up, GFR values decreased (Cr-GFR: 68.9 (57.7-76.8) vs. 58.6 (48.9-72.9), p=0.033 at 6-months and at the end, respectively). Significant negative correlations between triglycerides and cystatin C-based eGFR (ρ=-0.47, p=0.028) and Cr-Cys-eGFR (ρ=-0.45, p=0.043) at the end of the study were found. Conclusion: Our study showed a high number of overweight children undergoing kidney transplant. A negative correlation between triglycerides and GFR was found, which highlights the importance of managing nutritional status and regular blood lipids evaluation after kidney transplant.

title: Acute and chronic changes in porcine rete mirabile after embolization with the Menox system: angiographic and histopathological analyses

description: Abstract Objective: To evaluate acute and chronic changes seen on angiographic and histopathological studies of porcine rete mirabile, comparing those treated with the Menox liquid embolic system (LES) and those treated with the Onyx LES. Materials and Methods: Five pigs, each weighing approximately 35 kg, were submitted to rete mirabile embolization under general anesthesia and fluoroscopic guidance, with the Menox LES or Onyx LES. Four animals were treated with the Menox LES and underwent cerebral angiography, followed by euthanasia, at 1, 30, 60, and 90 days after embolization. One animal was treated with the Onyx LES underwent the same procedures at 30 days after embolization. In a subsequent histopathological analysis, we compared the Menox LES and Onyx LES in terms of the acute and chronic changes observed. Results: We observed no significant changes in blood pressure, heart rate, or electrocardiographic parameters that could be attributed to the super-selective infusion of dimethyl sulfoxide or the Menox embolic agent. Fluoroscopy showed adequate material opacity, appropriate progression to the center of the rete mirabile and complete unilateral embolization. Microcatheters were uneventfully detached from the embolized nidus. We observed mild to moderate intravascular and extravascular inflammatory responses, without histological evidence of necrotizing arteritis. There were no adverse neurovascular events. Conclusion: The Menox LES appears to be safe and effective, as well as being apparently equivalent to the Onyx LES in terms of the postprocedure angiographic and histopathological findings.

title: Premature newborn positionings and physiologic parameters – a randomized clinical study

description: Abstract Introduction Multiple studies have shown the effects of prone (PP), supine (SP) and kangaroo (KP) positions on clinical and physiological outcomes in preterm newborns, but none compared these three types of positioning between them. Objective To investigate the influence of these positionings on heart rate, respiratory rate, peripheral oxygen saturation (SpO2) and alertness status in clinically stable preterm newborns (NBs) admitted to a neonatal intensive care unit. Methods In a randomized clinical trial, clinically stable NBs with gestational ages from 30 to 37 weeks who were breathing spontaneously were allocated in three positioning groups: PP, SP and KP. Heart rate, breathing frequency, SpO2 and alertness status were evaluated immediately before and after 30 minutes of positioning. Results In all, 66 NBs were assessed (corrected age: 35.48 ± 1.94 weeks; weight: 1840.14 ± 361.09 g), (PP: n = 22; SP: n = 23; KP: n = 21). NBs in the PP group showed a significant improvement in peripheral SpO2 (97.18 ± 2.16 vs 95.47 ± 2.93 vs 95.57 ± 2.95, p = 0.03) compared with the SP and KP groups. Conclusion In clinically stable preterm NBs, the PP was associated with better peripheral oxygen saturation than the SP or KP. In addition, there was a reduction in heart rate within prone position group and in the KP group there was an increase in the number of NBs in the deep sleep classification.

title: Collaborative attitudes between pharmacists and physicians in Brazil

description: Abstract Pharmacist-physician collaboration is a strategy for optimizing patient care and improving health outcomes. Nevertheless, there is a lack of information in Brazil about collaborative practices among these professionals. The aim of this study was to measure collaborative attitude of pharmacists and physicians who were working together in a teaching hospital. A cross-sectional study was conducted from June 2018 to January 2019 with pharmacists and physicians working in a teaching hospital in Northeastern Brazil. These professionals were invited to provide responses to the Brazilian version of the “Scale of Attitudes Towards Pharmacist-Physician Collaboration” (SATP2C); their scores ranged between 16 and 64 points. The software Epi Info TM (version 3.5.4) was used for data analysis, and data were expressed in means. Forty-four professionals participated in this study. The mean age was 33.5 (DP = 7.1) years. More than half of participants were male (n = 25, 56.8%). The means from the SATP2C for pharmacists and physicians were 54.20 and 50.91, respectively, indicating good collaborative attitudes. There was no statistical difference between the mean scores of pharmacists and physicians. Participants showed a predisposition for collaborative teamwork. Future studies should focus on understanding the process by which collaboration translates into clinical practice.

title: EVALUATING PHYSICOCHEMICAL PROPERTIES OF MUTATED JATROPHA CURCAS SEED OILS AND THEIR FEASIBILITY AS NEW FEEDSTOCKS FOR BIODIESEL PRODUCTION

description: ABSTRACT The physicochemical properties of Jatropha curcas (JC) seed oils are related to the plant varieties and affect the biodiesel quality when it is used as feedstock. This work investigates the physicochemical properties and feasibility of mutated JC seed oil for biodiesel feedstock. Three mutated JC seed oils, from JC-150, JC-226 and JC-300, were successfully evaluated. The oil contents were determined by using gravimetry methods. The AV, FFA, IV and PV were determined by using titrimetric methods. Types of fatty acids were analyzed by using a GC-FID. The triacylglycerol (TAG) and PE compositions were determined by using a HPLC-ELSD. The results show that the oil contents of JC-150, JC-226 and JC-300 seeds were 48.3%, 45.8%, and 51.7%, respectively. The PE contents in JC-150, JC-226 and JC-300 were lower (approximately 33.4%, 46.9% and 96.4%) compared to the control. The oleic and linoleic acids were two main components of all samples, with compositions in the range 41.82-42.45% and 36.68-37.45%, respectively. The compositions of polyunsaturated and monounsaturated TAG were obtained in the range 71.60–76.22% and 19.62–24.53%, respectively. These results show that the properties of mutated JC seed oils meet with the requirements for biodiesel production.

title: Pharmacological blockade of protease-Activated Receptor 2 improves airway remodeling and lung inflammation in experimental allergic asthma

description: Abstract Protease-activated receptors (PARs) are metabotropic G-protein-coupled receptors that are activated via proteolytic cleavage of a specific sequence of amino acids in their N-terminal region. PAR2 has been implicated in mediating allergic airway inflammation. This study aims to study the effect of PAR2 antagonist ENMD1068in lung inflammation and airway remodeling in experimental asthma. Allergic lung inflammation was induced in sensitized BALB/c mice through intranasal instillations of ovalbumin (OVA), and mice were pretreated with ENMD1068 1 hour before each OVA challenge. Bronchoalveolar lavage fluid (BALF) was collected, and the lungs were removed at different time intervals after OVA challenge to analyze inflammation, airway remodeling and airway hyperresponsiveness. Ovalbumin promoted leukocyte infiltration into BALF in a PAR2-dependent manner. ENMD1068 impaired eosinophil peroxidase (EPO) and myeloperoxidase (MPO) activity in the lung parenchyma into BALF and reduced the loss of dynamic pulmonary compliance, lung resistance in response to methacholine, mucus production, collagen deposition and chemokine (C-C motif) ligand 5 expression compared to those in OVA-challenged mice. We propose that proteases released after an allergen challenge may be crucial to the development of allergic asthma in mice, and PAR2 blockade may be useful as a new pharmacological approach for the treatment of airway allergic diseases.
