College health providers' knowledge and confidence in addressing students' vaping: Evidence from a pilot study in New York State.

Objective: This study examines the knowledge and confidence of college healthcare providers in discussing vaping with their college student populations.

Methods: This is a mixed-methods descriptive study using a sequential-explanatory approach, consisting of a cross-sectional, online survey followed by qualitative interviews. Survey data was collected from 50 college health providers located at 26 colleges in the 64-campus State University of New York system.

Laser-assisted epicutaneous immunization to target human skin dendritic cells.

Dendritic cells (DC) are promising targets for immunotherapy of cancer. Clinically, immunization against cancer antigens by means of the most potent antigen-presenting cells, that is DC, remains an important treatment option in combination with the modern immune checkpoint approaches. Instead of adoptively transferring in vitro monocyte-derived DC, they can also be loaded in situ by antibody-mediated targeting of antigen.

A new trigemino-nociceptive stimulation model for event-related fMRI.

Functional imaging of human trigemino-nociceptive processing provides meaningful insights into altered pain processing in head and face pain diseases. Although functional magnetic resonance imaging (fMRI) offers high temporal and spatial resolution, most studies available were done with radioligand-positron emission tomography, as fMRI requires non-magnetic stimulus equipment and fast on-off conditions. We developed a new approach for painful stimulation of the trigeminal nerve that can be implemented within an event-related design using fMRI and aimed to detect increased blood-oxygen-level-dependent (BOLD) signals as surrogate markers of trigeminal pain processing.

Ultra-fast carotid CT-angiography: low versus standard volume contrast material protocol for a 128-slice CT-system.

Objectives: Noninvasive imaging is increasingly accepted for the evaluation of atherosclerotic disease of the carotid arteries. We sought to evaluate the feasibility of a low-contrast media volume protocol for carotid computed tomography angiography (CTA) using a 128-slice-spiral-computed tomography scanner with a gantry rotation time of 300 milliseconds.

Methods And Materials: Thirty consecutive patients underwent CTA for the evaluation of the carotid vessels, with a 128-section scanner.

[Dual-source CT: in vitro characterization of gallstones using dual energy analysis].

Purpose: Despite clinically available high-resolution CT, the detection and classification of gallstones remains a challenge in some cases. This pilot study examines whether noninvasive characterization of gallstones in vitro is possible using dual-energy analysis (DECT) of dual source CT datasets.

Materials And Methods: A total of 43 gallstones (0.

Transcranial sound field characterization.

In the scope of therapeutic ultrasound applications in the adult brain, such as sonothrombolysis in stroke, a better understanding of the intracranial acoustic properties during insonation through the temporal bone is warranted. Innovative ultrasound imaging techniques, like transcranial duplex sonography, may open new avenues to apply ultrasound for therapeutic purposes and to visually monitor the effect using the same device. The aim was to study the transcranial sound field aberrations and the changes of acoustic parameters, using a high-end duplex machine.

Transcranial ultrasound brain perfusion assessment with a contrast agent-specific imaging mode: results of a two-center trial.

Background And Purpose: The purpose of this study was to assess brain perfusion with an ultrasound contrast-specific imaging mode and to prove if the results are comparable between 2 centers using a standardized study protocol.

Methods: A total of 32 individuals without known cerebrovascular disease were included in the study. Perfusion studies were performed ipsilaterally in an axial diencephalic plane after intravenous administration of 0.

Operations on patients deemed "unfit for operation and anaesthesia": what are the consequences?

Background: The decision "patient unfit for anaesthesia and operation" is likely to cause a delay of the scheduled operation. This retrospective evaluation was done: 1) to determine the correctness of preoperative tentative diagnoses of coexisting diseases making anaesthesia and operation excessively risky in relation to the physician's training status; 2) to examine the question of whether preoperative medical management modified according to the anaesthesiologist's suggestions had a positive impact on the perioperative course.

Methods: The medical records of patients scheduled for elective non-cardiac surgery who were rated "unfit for operation and anaesthesia" were evaluated.

Prehospital point of care testing of blood gases and electrolytes - an evaluation of IRMA.

BACKGROUND: This study evaluated the feasibility of blood gas analysis and electrolyte measurements during emergency transport prior to hospital admission. RESULTS: A portable, battery-powered blood analyzer was used on patients in life threatening conditions to determine pH, pCO2, pO2, sodium, potassium and ionized calcium. Arterial blood was used for blood gas analysis and electrolyte measurements.
