Objective: This meta-analysis sought to investigate if IVUS-guided PCI (IVUS-PCI) can improve outcomes compared to standard PCI and CABG in patients with multivessel CAD.
Background: Coronary artery disease (CAD) is traditionally revascularized by either percutaneous coronary intervention (PCI) or coronary artery bypass (CABG) with a historical benefit of CABG over PCI in multivessel CAD. Intravascular ultrasound-guided PCI (IVUS-PCI) may improve outcomes compared to angiography alone.
Blast-related mild traumatic brain injury (blast-mTBI) can result in a spectrum of persistent symptoms leading to substantial functional impairment and reduced quality of life. Clinical evaluation and discernment from other conditions common to military service can be challenging and subject to patient recall bias and the limitations of available assessment measures. The need for objective biomarkers to facilitate accurate diagnosis, not just for symptom management and rehabilitation but for prognostication and disability compensation purposes is clear.

Perivascular spaces (PVS) are a key part of the glymphatic system which supports brain waste clearance, preferentially during sleep. Visible PVS on clinical magnetic resonance imaging have been previously observed in patients with neurodegenerative diseases and animal neurotrauma models.

Exposure to repetitive mild traumatic brain injuries is associated with persistent behavioural, cognitive, emotional and neurological symptoms later in life. Identifying neurophysiological changes associated with mild traumatic brain injury exposure, in the absence of present-day symptoms, is necessary for detecting future neurological risk.

Individuals who completed at least one year of varsity collegiate football were eligible to participate in this observational cohort study (n = 48; aged 36-41 years; 79.2% white/Caucasian; 12.

Gameplay characteristics, including player position and session type, may contribute to these relationships but have not been prospectively examined. The current study aimed to determine if an association exists between head impact biomechanics and physical load metrics.

The link between cumulative subconcussive blasts on short- and long-term neurological impairment is largely understudied. Neurodegenerative diseases such as brain dysfunction, cognitive decline, mild cognitive impairment, and dementia may develop with chronic exposures.

Hypopituitarism is an mTBI sequela; however, few studies have examined this phenomenon in those with an mTBI history. This cross-sectional study of Special Operations Forces combat soldiers aimed 1) to relate anterior pituitary gland volumes (actual and normalized) to insulin-like growth factor 1 (IGF-1) concentrations, 2) to examine the effect of mTBI history on anterior pituitary gland volumes (actual and normalized) and IGF-1 concentrations, and 3) to measure the odds of demonstrating lower anterior pituitary gland volumes (actual and normalized) or IGF-1 concentrations if self-reporting mTBI history.

Studies of former athletes at early-midlife are limited. We investigated the association between RHI exposure and gray matter (GM) structure, as well as moderating factors, among former athletes in early-midlife.

We have developed oxygen filled microbubbles, SE61 for localized, ultrasound-triggered oxygen delivery to hypoxic tumors prior to radiation therapy. Microbubbles, created by sonication, have a shell composed of D-α-Tocopherol polyethylene glycol 1000 succinate (TPGS) and sorbitan monostearate. Preliminary studies in mice with breast tumor xenographs showed that increases in oxygen partial pressure levels lasted less than 3 min, which is insufficient for most clinical applications.

Objective: To compare BFA with standard pharmacologic interventions to treat patients in the emergency department (ED) with low back pain.
Methods: We conducted a nonblinded randomized controlled trial of a convenience sample of adults presenting to an urban tertiary care ED with a chief complaint of low back pain.
Context: The first men's wrestling National Collegiate Athletic Association (NCAA) Championship was sponsored in 1928; since then, participation has increased.
Background: Continued study of wrestling injury data is essential to identify areas for intervention based on emerging trends.
Methods: Exposure and injury data collected in the NCAA Injury Surveillance Program during 2014-2015 through 2018-2019 were analyzed.
Context: Football is among the most popular collegiate sports in the United States, and participation in National Collegiate Athletic Association (NCAA) football has risen in recent years.
Background: Continued monitoring of football injuries is important for capturing the evolving burden of injuries in NCAA football. The purpose of this study was to describe the epidemiology of football-related injuries among men's NCAA football players during the 2014-2015 through 2018-2019 academic years.
Context: The National Collegiate Athletic Association has supported men's baseball championships since 1947. Since its inception, the number of participating teams and athletes has considerably expanded.
Background: Frequently conducting injury surveillance of collegiate baseball athletes is essential for identifying developing temporal patterns.
Identifying the associations between head impact biomechanics and clinical recovery may inform better head impact monitoring procedures and identify athletes who may benefit from early treatments aimed to enhance recovery. The purpose of this study was to test whether head injury biomechanics are associated with clinical recovery of symptom severity, balance, and mental status, as well as symptom resolution time (SRT) and return-to-participation (RTP) time. We studied 45 college American football players (n = 51 concussions) who sustained an incident concussion while participating in a multi-site study.

Repetitive mTBI may increase the risk of developing long-term neurological sequelae. Identifying changes in neuroinflammatory biomarkers before chronic conditions emerge could serve as preliminary evidence of developing neuropathology.

We report a case of peripherally inserted central catheter (PICC) migration and perforation of the left internal jugular vein in a home health setting in an 80-year-old female. A left sided PICC was placed for treatment of diverticulitis following hospital discharge. She complained of sudden onset left sided neck pain immediately after starting an infusion of vancomycin.

Historically, J and J studies have emphasized 2 and 3-bond couplings, yet J couplings exhibit significantly larger variations. Moreover, recent improvements in experimental measurement and data processing methods have made J data more available.

This behavior has been rationalized in terms of packing density at the hydrocarbon tails, with COOH hydrogen bonding considered to be invariant among different acids. A recent ambiguity involving the COOH conformation between two crystal structures of lauric acid suggests that COOH structure and hydrogen bonding may play a role in these differences.
