AI Article Synopsis
- The study aimed to investigate how gender impacts the hemodynamic response (blood pressure and heart rate) during anesthesia induction and intubation in young adults.
- Participants included 83 healthy individuals aged 20-30, randomized into three groups with varying doses of anesthetics.
- Results showed that women had lower systolic and diastolic blood pressure compared to men, particularly before and after intubation, indicating gender-related differences in hemodynamic responses to anesthesia.
Article Abstract
Study Objectives: To determine whether gender affects the hemodynamic response to anesthesia induction and intubation in young adults.
Design: Randomized clinical trial.
Setting: University hospital.
Patients: 83 healthy patients, aged 20 to 30 years, scheduled for orthopedic, plastic, and general surgery.
Interventions: Patients were randomly allocated to one of three groups: Anesthesia was induced with fentanyl 1.5 microg/kg and thiopental 3 mg/kg in Group 1 (n = 28, men) and Group 2 (n = 28, women), or fentanyl 1.5 microg/kg and thiopental 2 mg/kg in Group 3 (n= 27, women) and maintained with enflurane 1% in N2O-O2 throughout the observational period. Three minutes after induction, direct laryngoscopy and intubation were performed.
Measurements: Noninvasive systolic (SBP) and diastolic (DBP) blood pressures, and heart rate (HR) were recorded before induction (baseline), immediately before intubation, immediately after intubation, and then every 1 minute for 5 minutes after intubation.
Results: SBP, DBP, and HR did not differ between men and women at baseline. However, SBP and DBP were lower in women than in men (p < 0.05) and immediately before intubation and at overall time points after intubation. There were no significant differences noted in SBP, DBP, and HR between Groups 2 and 3. When compared with baseline values, SBP and DBP were decreased in women, whereas only DBP was decreased in men immediately before intubation (p < 0.05). The increase in SBP was more prolonged in men after intubation.
Conclusions: Pressor response is different in women than men, suggesting the difference of the response might result from the gender differences.

Physiological effects of hand grip and cold pressor tests in young Saudi adults.

The risk of cardiovascular disease differs among various ethnic groups, highlighting disparities in cardiovascular health among different populations. While multiple studies from other countries have looked at changes in physiological parameters during autonomic function tests like isometric handgrip and cold pressor tests, no correlational research has been done in Saudi Arabia. This lacuna underscores the importance of examining the relationship between cardiorespiratory parameters in young Saudi Arabian individuals during these tests.

Objective: This study explores the associations between various sleep durations and metabolic health indices, including systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol levels, high-density lipoprotein (HDL) cholesterol, and waist circumference.
Methods: Data from the National Health and Nutrition Examination Survey (NHANES) 2021 to 2023, were analyzed. MANOVA and Bonferroni-adjusted ANOVAs were conducted to examine the relationships between sleep duration (sleep deprivation (≤5 h), short sleep (5-7 h), recommended sleep (7-9 h), and long sleep (>9 h)) and metabolic health indices.
Objective: Aim: To investigate the effects of exercise training on heart rate and blood pressure in soccer players of different skill levels.
Patients And Methods: Materials and Methods: 693 soccer players with different sports qualifications were studied. Heart rate (HR) and blood pressure (BP) were measured at rest at the beginning of the preparatory phase of the training cycle.
Impact of cariprazine on body weight and blood pressure among adults with bipolar I disorder, schizophrenia, or major depressive disorder in a real-world setting.

AbbVie, North Chicago, IL, USA.
Background: Atypical antipsychotics are a common treatment for serious mental illness, but many are associated with adverse effects, including weight gain and cardiovascular issues, and real-world experience may differ from clinical trial data. Cariprazine has previously demonstrated a favorable safety and tolerability profile in clinical trials. Here, we evaluated the effects of cariprazine on body weight and blood pressure for bipolar I disorder (BP-I), schizophrenia, or as adjunctive treatment for major depressive disorder (MDD) using real-world data.

To explore the effects of obstructive sleep apnea (OSA) on nocturnal changes in blood pressure (BP), we enrolled 2037 participants who underwent polysomnography (PSG) between 2019 and 2020 and examined BP changes before and after sleep. BP was measured in the evening and the following morning using an electronic wrist sphygmomanometer in the supine position. The severity of OSA was determined by PSG and graded based on the apnea/hypopnea index (AHI).
