1. Effects of lidocaine and esmolol on hemodynamic response to tracheal intubation: a randomized clinical trial
Abstract Introduction and objectives: Although lidocaine is widely used to prevent cardiovascular changes resulting from laryngoscopy and orotracheal intubation, it is still unclear whether there are more efficacious drugs. This study aimed to compare the beta-blocker esmolol with lidocaine regarding the effects on hemodynamic response after orotracheal int

2. Learning Curve in Left Ventricular Assist Device Implantation: Low Volumes Do Not Equate Bad Outcomes
ABSTRACT Introduction: Most implantations of left ventricular assist devices (LVAD) are performed in low-volume centers. This study aimed to evaluate the procedural learning curve of HeartMate II (HM2) implantations by comparing outcomes between two time periods in a low-volume center. Methods: All 51 consecutive patients undergoing HM2 implantation betwee

3. Maintenance of plasma glucose variability after an acute session of aerobic exercise despite changes in insulin and glucagon-like peptide-1 levels in type 2 diabetes
ABSTRACT Objective: The present study aimed to evaluate glucose variability and hormonal responses during and after an aerobic exercise session performed after breakfast in type 2 diabetes patients treated with metformin. Materials and methods: In this quasi-experimental study individuals underwent clinical and laboratory evaluations and maximal exercise t

4. Continuous clonidine infusion: an alternative for children on mechanical ventilation
SUMMARY OBJECTIVE: This study aimed to assess the clonidine infusion rate in the first 6 h, as maintenance dose (first 24 h), and in the pre-extubation period (last 24 h), as well as the cumulative dose of other sedatives and the hemodynamic response. METHODS: This is a retrospective cohort study. RESULTS: Children up to the age of 2 years who were admitt

5. The effect of 1-mg versus 3-mg granisetron on shivering and nausea in cesarean section: a randomized, controlled, triple-blind, clinical trial
Abstract Introduction: Intra- and postoperative nausea, vomiting and shivering are mentioned as the most common problem following spinal anesthesia. The aim of this study is to compare two different doses of granisetron to control the shivering, nausea, and vomiting caused by spinal anesthesia in women undergoing cesarean section (C/S). Method: This study

6. Comparison between dexmedetomidine and fentanyl bolus in attenuating the stress response to laryngoscopy and tracheal intubation: a randomized double-blind trial
Abstract Background and objectives: Laryngoscopy and tracheal intubation lead to a sympathoadrenal response. We compared the efficacy of dexmedetomidine with fentanyl bolus to attenuate this response. Methods: One hundred patients admitted for routine surgical procedures under general anesthesia were enrolled in this double blind, randomized, controlled st

7. Home-Based Resistance Training in Heart Diseases: Don't Stop the Music, your Muscles are still Listening
Abstract Background: Nasal mucociliary clearance (NMC) responds to autonomic activity through exercise. However, there is a gap in the literature on how NMC responds to resistance exercise. Objective: To evaluate the acute effects of resistance tube exercise on NMC and the autonomic nervous system in smokers. Methods: Clinical trial was performed with 18

9. A single session of low-volume high-intensity interval and moderate-intensity continuous exercise elicits a transient reduction in ghrelin levels, but not in post-exercise energy intake in obese men
ABSTRACT Objective: This study investigated the acute effects of high-intensity interval (HIIE) and moderate-intensity continuous (MICE) exercise on ghrelin levels in obese men. Subjects and methods: A total of 10 obese men (age 27.6 ± 1.8 years, body mass index 35.4 ± 4.5 kg/m², body fat 39.9 ± 2.1%) performed two exercise sessions in a randomized ord

10. Hypotension and Bradycardia Produced by Transthoracic Application of Low-Intensity Ultrasound Therapy in Hearts of Healthy Rats - A Preclinical Study
Abstract Objective: To investigate the cardiovascular effects produced by transthoracic application of low-intensity pulsed ultrasound therapy (LIPUST). Methods: Three-month-old male Wistar rats (± 300 g, N=16) were randomly allocated in two groups, namely SHAM (control group, faked procedures) and UST (animals treated with LIPUST). These animals, under a

11. Electrocardiographic Abnormalities in Hypertension Models
Abstract Background: Hypertensive condition can lead to abnormalities in heart structure and electrical activity. The electrocardiogram (ECG) is a recording of the electrical activity of the heart and widely used to diagnose and detect heart problem. Objective: We conducted a comparative ECG analysis between two hypertension models (L-NAME and SHR) and the

12. Characterization of the intestinal graft in a swine hypotensive after brain death model
Abstract Purpose: To establish a hypotensive brain death pig model and observe the effects of hypotension on small bowel donors. Methods: The hypotensive brain death model was produced using the modified intracranial water sac inflation method in ten domestic crossbred pigs. Effects of hypotensive brain death on small bowel tissue morphology were evaluated
