Article Abstract
Background: Regular and moderate exercise is beneficial for improving the efficiency of the heart, but high-intensity physical activity may result in cardiac changes.
Objectives: This study focuses on the identification of the differences in echocardiography and blood variables before exercise, as well as the genes associated with cardiac hypertrophy at rest and in response to graded exercise test.
Material And Methods: The study group was made up of 28 road cyclists. Echocardiographic parameters and blood pressure were measured before exercise tests (N = 28). Blood samples were collected at rest, at maximal exercise intensity in a graded bicycle test and after 15 min of recovery; afterwards, blood morphology was estimated and RNA was isolated. Analysis of the expression profile of genes was performed for randomly selected road cyclists using the microarray method.
Results: Echocardiographic results and blood parameters divided cyclists into two groups: with and without left ventricular hypertrophy (N = 14). Differences in the structure and function of the left ventricle cyclists with a similar level of training were observed (p < 0.05). Diastolic blood pressure and resting heart rate were significantly lower in subjects with left ventricular hypertrophy (p < 0.05). The myosin light chain 9 and interleukin-6 signal transducer gene expression were differentially regulated in cyclists with left ventricular hypertrophy compared to athletes with normal heart dimensions in response to intensive exercise.
Conclusions: We have found differences in echocardiography parameters, blood pressure, stroke volume and maximal power in the cyclists examined. These studies indicate the benefits of the recommended echocardiography measurements for professional endurance-athletes. The graded exercise altered the myosin light chain 9 and interleukin-6 signal transducer gene expression in the peripheral blood of road cyclists has also been found.

Is Intracranial Pressure Monitoring After Open Cranial Procedures Associated With Outcome?
J Surg Res
January 2025
Division of Trauma and Critical Care, Department of Surgery, Reading Hospital, West Reading, Pennsylvania. Electronic address:
Introduction: It is unclear if intracranial pressure monitoring (ICPM) after open cranial procedures (craniotomy or craniectomy) (OC) for traumatic brain injury is associated with mortality. We hypothesized that ICPM placed early after OC was associated with lower mortality compared to no ICPM or delayed ICPM placement.
Methods: Using 2020-2021 data from the American College of Surgeons Trauma Quality Improvement Program, patients ≥16 y from level 1 and 2 trauma centers who underwent OC were divided into two groups: ICPM placed within 72 h of OC (early) and no ICPM or ICPM placed after 72 h (none/delayed).
Vitreous cavity lavage with a bended-needle system for postoperative vitreous cavity hemorrhage.
Retina

Department of Ophthalmology, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences, Beijing, China.
Purpose: To present a novel bended-needle drainage system in vitreous cavity lavage (VCL) for postoperative vitreous cavity hemorrhage (POVCH).
Methods: This retrospective case series include all patients with POVCH who received VCL with the bended-needle drainage system at ophthalmology department of Peking Union Medical College Hospital from January 2022 to May 2024. Patients adopted a supine position that allows preparation and draping.
Rare Indocyanine-Induced Anaphylactic Shock During Deep Inferior Epigastric Artery Perforator Breast Reconstruction: A Case Report.

From the Department of Plastic and Reconstructive Surgery, Ewha Womans University College of Medicine, Mokdong Hospital, Seoul, Republic of Korea.
Indocyanine green (ICG) is a water-soluble green substance that is detectable through infrared cameras and emits greenish light. Approved for medical use in the 1950s, ICG has gained prominence as a real-time visualization tool. Widely recognized as a generally safe substance, ICG is applied in diverse fields.

Sanford Children's Hospital, Sioux Falls, South Dakota.
Background: Propofol is commonly used for pediatric MRIs to minimize patient movement. At our institution, intensivists typically administer a prophylactic 20 ml/kg saline bolus to maintain blood pressure (BP) during propofol sedation. This quality improvement project assessed whether a 10 ml/kg and a completely eliminated saline bolus are as effective as the standard 20 ml/kg bolus in completing pediatric propofol sedation and maintaining Mean Arterial Pressure (MAP).

Department of Women and Children's Health, School of Life Course and Population Sciences, Faculty of Life Sciences and Medicine, King's College London, London, United Kingdom.
Background: In 2017, the American College of Cardiology and American Heart Association (ACC/AHA) lowered blood pressure (BP) thresholds to define hypertension in adults outside pregnancy. If used in pregnancy, these lower thresholds may identify women at increased risk of adverse outcomes, which would be particularly useful to risk-stratify nulliparous women. In this secondary analysis of the SCOPE cohort, we asked whether, among standard-risk nulliparous women, the ACC/AHA BP categories could identify women at increased risk for adverse outcomes.
