title: Oral administration of eucalyptol reduces cell migration and pain-like behavior in zymosan-induced arthritis mice

description: Abstract Rheumatoid arthritis (RA) is an inflammatory disease that utilizes nonbiologic and biologic drugs for appropriate disease management. However, high cost, adverse effects, reduced effectiveness, and risk of infection have stimulated the search for safer and more efficacious therapeutic strategies. In the present study, we aimed to evaluate the anti-inflammatory and analgesic properties of eucalyptol in an experimental model of arthritis. Mice were administered zymosan or saline intra-articularly. One hour before the zymosan administration, the mice were treated with oral eucalyptol (200-400 mg/kg) and vehicle. Cell influx, neutrophils, lymphocytes, and monocytes were measured in joint exudates. Joint pain was assessed using paw-pressure tests. Orally administered eucalyptol (200 and 400 mg/kg) significantly reduced cell influx, as well as neutrophils, lymphocytes, and monocytes, when compared with the control. Eucalyptol at a dose of 400 mg/kg significantly reversed joint pain and demonstrated analgesic activity (60%); however, 200 mg/kg failed to alter joint pain. These results indicate that oral eucalyptol promotes anti-inflammatory and analgesic activity in mice subjected to zymosan-induced arthritis.

title: S-allyl Cysteine and Taurine revert peripheral metabolic and lipid profile in non-insulin-dependent diabetes mellitus animals: Combination vs Monotherapy

description: Abstract The present study was designed to evaluate the beneficial synergistic effects of S-allyl Cysteine (SAC) and Taurine (TAU) on hyperglycemia, lipid profile and renal damage markers in type 2 diabetes mellitus (T2DM) in rats. Experimental T2DM was developed by administering an intraperitoneal single dose of nicotinamide (NA; 230 mg/kg) and streptozotocin (STZ; 65 mg/ kg) in adult rats. Control and diabetic rats were treated with SAC (150 mg/kg); TAU (200 mg/ kg) or SAC and TAU (75+100 mg/kg) combination for four weeks. Measurements of traditional markers of kidney toxicity in serum, such as blood urea nitrogen (BUN), serum creatinine (Scr), and alkaline phosphatase (ALP), together with serum cholesterol/triglyceride such as serum total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and very low-density lipoprotein cholesterol (VLDL-C) may yield a snapshot of renal damage and lipid profile in NA/STZ-treated rats. The variation in levels of fasting blood glucose, glycosylated hemoglobin, insulin and lipid profile was significantly augmented in SAC/TAU treatment group. The diabetic group showed elevated renal injury markers in serum, which were decreased significantly by SAC/TAU treatment. Thus the results of the experiment clearly indicate the potential of the SAC/TAU combination in improving diabetic complications.

title: Using drug chemical structures in the education of pharmacology and clinical therapeutics key concepts

description: Abstract Medicinal chemistry made it possible for pharmacists to propose pharmacodynamics and pharmacokinetics explanations of many existing drugs. Moreover, medicinal chemistry education provides pharmacy students with a reasonable understanding of drug physicochemical properties, mechanism of action (MOA), side effects, metabolism and structure-activity relationship (SAR). This paper highlights the importance of these medicinal chemistry key elements in understanding other pharmacy core courses, mainly pharmacology and clinical therapeutics. Such elements can be utilized as a tool for pharmacists while training or counseling their patients on the use of their treatments. Different new examples from the literature have been incorporated in this paper to show how chemical structures of existing drugs can provide essential information about main concepts in the education of pharmacology and clinical therapeutics, and the key structural elements for the discovery and development of other same class drugs.

title: Acute Effects of Dietary Nitrate on Central Pressure and Endothelial Function in Hypertensive Patients: A Randomized, Placebo-Controlled Crossover Study

description: Abstract Background The diet’s inorganic nitrate (NO3–) may provide a physiological substrate for reducing nitrate (NO2–) to NO independent of the endothelium. Studies suggest that inorganic NO3– has beneficial effects on cardiovascular health. Objective This study evaluated the acute effects of 500 mL nitrate-rich beetroot juice (BRJ; containing 11.5mmol NO3–) on blood pressure and endothelial function in treated hypertensive patients. Methods A randomized, placebo-controlled, crossover study was conducted in treated hypertensive patients (n=37; women=62%) who underwent clinical and nutritional evaluation and assessment of central hemodynamic parameters and microvascular reactivity. The significance level was p&lt;0.05. Results The mean age was 59±7 years, and mean systolic and diastolic blood pressures were 142±10/83±9mmHg. There was a significant increase in the subendocardial viability ratio (SEVR; 149±25 vs. 165±30%, p&lt;0.001) and reduction in ejection duration (ED; 37±4 vs. 34±4%, p&lt;0.001) in the beetroot phase but no significant SEVR difference in the control phase. The % increase in perfusion (155 vs. 159 %, p=0.042) was significantly increased in the beetroot phase, which was not observed in the control phase. In the beetroot phase, the change in SEVR showed a significant correlation with the change in the area under the curve of post-occlusive reactive hyperemia (AUC-PORH) (r=0.45, p=0.012). The change in ED showed a significant correlation with the post-intervention perfusion peak (r=-0.37, p=0.031) and AUC-PORH (r=-0.36, p=0.046). Conclusions The acute ingestion of BRJ by hypertensive patients resulted in an improvement of endothelial function, which was associated with higher subendocardial viability and performance in myocardial contraction.

title: Overview of general surgery medical residency programs and prerequisite program in basic surgical area in Brazil: Historical review and update

description: ABSTRACT Objective: to describe vacancy regulation process by adding, describing the panorama of the General Surgery Residency Program (PRMCG) and the Basic Surgical Prerequisites Program (PRACB). Method: descriptive, quali-quantitative, cross sectional study conducted from document analysis from National Commission of Medical Residency (CNRM). Results: in 2018, after evaluation of the General Surgery Services for adequacy of the number of vacancies (DS), the PRACB was instituted as a modality of access to surgical specialties until definitive change in the time of the formation of the general surgeon for three years, in 2022. In the first addition of vacancies in 2018, 127 PRMCG were authorized with 736 vacancies of R1 and 290 PRACB (2 years) with 1.286 vacancies offered for R1. In the second addition in 2021, 423 PRM were authorized with 1.564 R1 vacancies in PRMCG. Discussion: the regulation of the offer of vacancies for the formation of specialties in Brazil should align the evaluation of practice scenarios with the profile of skills. The PRACB modality was instituted for a certain time for budgetary preparation and practice scenarios until the complete transition to training in 3 years. Conclusion: Brazil by 2018 was the only country to grant the Board Certification to General Surgeon with only 2 years of training. After a transitional period the same analysis methodology for adding and regulating vacancies was applied to services.

title: Pharmacists’ Educational Training and Professional Activities at the Municipal Level of the Brazilian National Health System

description: Abstract Brazilian pharmacists’ education and training aims to prepare them for the various activities they will undertake during professional practice, especially in the national health system (SUS). By using an exploratory transversal study based on a validated questionnaire, we have characterized the educational and training background of pharmacists working in SUS municipal units in Ribeirão Preto, State of São Paulo (SP), Brazil, and the frequency with which these professionals carry out several activities. Pharmacists working in these municipal outpatient units (N=44) graduated between 1981 and 2014 (56.8% of them graduated from public state or federal institutions), are predominantly female (84%), and are aged 25-57 years; 34% of these pharmacists have a “Generalist” degree, and 90.9% attended postgraduate programs, mostly specialization (75%). All the pharmacists pointed out the need for continuing education. The frequency with which they carry out activities varies, but those involving direct contact with patients predominate. Consultations, therapeutic follow-up, case discussions, and health promotion activities take place only occasionally. We concluded that pharmacists who work in the municipality of Ribeirão Preto, SP, are very much involved with dispensing, but not with health education or pharmacotherapeutic follow-up, so investing in education and training in these areas is necessary.

title: Impact of telemedicine on metabolic control and hospitalization of peritoneal dialysis patients during the COVID-19 pandemic: a national multicentric cohort study

description: Abstract Introduction: The coronavirus-19 pandemic threatens the lives of all people, but results in higher mortality rates for patients with end-stage kidney disease (ESKD) including those on peritoneal dialysis (PD). Telemedicine was the main alternative to reduce exposure to the virus, but it was introduced in the Brazil without proper training. Objective: To investigate the impact of telemedicine on metabolic control, peritonitis rates, and hospitalization in PD patients during the pandemic. Methods: This was a retrospective multicenter cohort study. We included all adult patients on chronic PD from 9 clinics selected by convenience during the pandemic. The outcomes of interest were measured and compared between before and after switching to telemedicine using repeated measure analysis and multilevel Poisson regression. Results: The study included 747 patients with a mean age of 59.7±16.6 years, of whom 53.7% were male and 40.8% had diabetes. Biochemical parameters including hemoglobin, potassium, phosphate, calcium, and urea serum levels did not change significantly after transition to telemedicine. There was no association between telemedicine and peritonitis rates. In contrast, hospitalization rates increased significantly in the telemedicine period. The incidence rate ratio (IRR) for hospitalization in the telemedicine period was 1.54 (95%CI 1.10-2.17; p 0.012) and 1.57 (95%CI 1.12-2.21; p 0.009) in the mixed-effects Poisson regression before and after adjustment for the presence of confounders. Admissions for hypervolemia and infections not related to PD doubled after transition to telemedicine. Conclusion: The implementation of telemedicine without proper training may lead to an increase in adverse events in PD patients.
