13. Simple and fast process using hydrochloric acid for producing synthetic zinc-rich stevensite
Abstract In the last decades, clays have been used in sectors such as health and cosmetics. This requires products that are increasingly pure and present homogeneous properties, hardly found in natural clays. The use of synthetic clays can be a solution. For this, it is necessary to explore techniques for their production. The main focus of this study was to

14. Comparison between intravenous and intrathecal clonidine for postoperative analgesia of patients submitted to laparoscopic cholecystectomy: randomized clinical trial
Abstract Introduction and objectives: Alpha2 adrenergic agonists, such as clonidine, are used as adjuvants during anesthesia due to their analgesic, sedative, and cardiovascular effects. The objective of the present study was to compare the effect of clonidine administered intravenously and intrathecally on the postoperative pain score of patients undergoin

15. The Influence of the Platinum Weight Percentage in the Catalyst Formulation on the Performance of a High Temperature Ethanol Electroreformer Based on H3PO4 Doped Polybenzimidazole for Green Hydrogen Production
A vapor-fed high temperature proton exchange ethanol electroreformer has been developed based on the use of a H3PO4-doped polybenzimidazole membrane to produce green hydrogen. As a key parameter, this article describes the influence of platinum weight percent (wt.%) in the catalyst formulation from different commercial catalysts (20, 40, 60, 80 wt.% Pt/C and

16. Retrospective Evaluation of Platelet-Leukocyte Indices and Cardiac Surgical Outcomes in Acyanotic Heart Disease Patients with Pulmonary Hypertension (REPLICA-PH)
Abstract Introduction: Acyanotic congenital heart disease (ACHD) patients with pulmonary hypertension (PH) are prone to postoperative complications, and characterization of the risk profile continues to fail in identifying inflammatory predilection. Our objective is to investigate the role of platelet-leukocyte indices (neutrophil-lymphocyte ratio [NLR], pl

17. Text Messages to Promote Secondary Prevention after Acute Coronary Syndrome (IMPACS trial)
Abstract Background Short message service (SMS) to promote healthcare improves the control of cardiovascular risk factors, but there is a lack of evidence in low and middle-income countries, particularly after acute coronary syndromes (ACS). Objective This study aims to evaluate whether the use of SMS increases risk factor control after hospital discharg

18. Association of Anti-β1 and Anti-M2 Antibodies with Autonomic Nervous System Modulation in Patients with Chronic Chagas Cardiomyopathy
Abstract Background: Different immune mechanisms of myocardial damage involved in the pathophysiology of Chagas disease coexist with high titers of autoantibodies induced by T. cruzi . There are few studies in the literature about the adaptive role of anti-β1 and anti-M2 antibodies in chronic Chagas cardiomyopathy (CCC). Objectives: To evaluate the associ

19. Influence of unstable shoes on women with lumbopelvic postpartum pain: randomized clinical trial
ABSTRACT BACKGROUND: Back pain is a normal symptom during pregnancy and is expected to become worse beyond the first three months after childbirth. OBJECTIVES: To determine the effectiveness of wearing unstable shoes instead of conventional shoes, regarding pain intensity, low back mobility and stability, among women with lumbopelvic pain (LPP) during the

20. RE: Impact of COVID-19 on a urology residency program
ABSTRACT Introduction: Ureteroceles present a diagnostic and treatment challenge in adults (1). With an estimated prevalence of 1/500 to 1/4000, it is not uncommon for any urologist to encounter ureteroceles in clinical practice (2). The incidence of prolapsed ureteroceles in adults is unknown (3). Materials and Methods: We present an interesting case of a

22. Vegetarian Diets and Cardiovascular Risk in Women
Abstract Introduction: Vegetarian diets have favorable effects on cardiovascular risk, provided that they do not contain ultra-processed foods (UPF). Objective: To compare the metabolic profile, cardiovascular risk, body composition, and food consumption in vegan (VEG), lacto-ovo vegetarian (LOV), and omnivorous (OMNI) women. To verify the association betw

24. Potential Impact of the New American High Blood Pressure Guidelines on Hypertension Prevalence in a Primary Health Care Unit in Rio de Janeiro – the LapARC Study
Abstract Background The new American Heart Association guidelines for hypertension (HT) proposed a reduction of the diagnostic cut-off point, leading to a substantial increase in the prevalence of HT. Objectives To assess the prevalence of HT determined by the traditional criteria, the AHA criteria, and home blood pressure monitoring (HBPM) in a population
