Meniscal integrity is a prerequisite for sustained knee joint health and prevention of meniscal degeneration is a main research goal. Cartilage-protective effects of selenium have been described, but little is known about the impact on the meniscus. We therefore investigated the influence of sodium selenite on meniscal explants under tumor necrosis factor-alpha (TNFα)-stimulated proinflammatory conditions. Meniscal explant disks (3 mm diameter × 1 mm thickness) were isolated from 2-year-old cattle and incubated with TNFα (10 ng/ml) and sodium selenite (low dose, LoD 6...

PURPOSE: The dose-response of radiochromic film has been shown to be dependent on the quality of the incident radiation, particularly at low energies. Difficulty therefore arises when a calibration is required for radiation of uncertain energy. This study investigates the ability of a recently published calibration method [see M. Tamponi et al., "A new form of the calibration curve in radiochromic dosimetry. Properties and results," Med. Phys. 43, 4435-4446 (2016)] to reduce the energy-dependence of radiochromic film...

Elderly trauma patients may be at increased risk for underassessment and inadequate pain control in the emergency department (ED). We sought to characterize risk factors for oligoanalgesia in the ED in elderly trauma patients and determine whether it impacts outcomes in elderly trauma patients. We included elderly patients (age ≥55 years) with Glasgow Coma Scale scores 13 to 15 and Injury Severity Score (ISS) ≥9 admitted through the ED at a Level I trauma center. Patient characteristics and outcomes were compared between those who reported pain and received analgesics medication in the ED (MED) and those who did not (NO MED)...

BACKGROUND: Arterial gas embolism (AGE) is a rare condition in the flying community most often only ever seen in flight while operating at high altitude or incidents involving hypobaric chambers. This article describes a severe case of AGE that occurred in a pilot of a fourth generation fighter aircraft at ground level. The environmental control system (ECS) malfunctioned, causing an overpressurized cockpit and a subsequent explosive decompression when the pilot opened the canopy to egress...

The Stratex Project is a high altitude balloon flight that culminated in a freefall from 41,422 m (135,890 ft), breaking the record for the highest freefall to date. Crew recovery operations required an innovative approach due to the unique nature of the event as well as the equipment involved. The parachutist donned a custom space suit similar to a NASA Extravehicular Mobility Unit (EMU), with life support system mounted to the front and a parachute on the back. This space suit had a metal structure around the torso, which, in conjunction with the parachute and life support assembly, created a significant barrier to extraction from the suit in the event of a medical emergency...

INTRODUCTION: Long-duration space explorations will involve significant communication delays that will likely impact individual and team outcomes. However, the extent of these impacts and the appropriate countermeasures for their mitigation remain largely unknown. This study examined the feasibility and acceptability of utilizing the International Space Station (ISS) as a research platform to assess the impacts of communication delays on individual and team behavior and performance. METHODS: For this study, 3 ISS crewmembers and 18 mission support personnel performed 10 tasks identified by subject matter experts as meeting study criteria, 6 tasks without a delay in communication and 4 tasks with a 50-s one-way delay...

INTRODUCTION: This paper investigates personality traits as potential factors for success in an astronaut selection by comparing personality profiles of unsuccessful and successful astronaut candidates in different phases of the ESA selection procedure. It is further addressed whether personality traits could predict an overall assessment rating at the end of the selection. METHODS: In 2008/2009, ESA performed an astronaut selection with 902 candidates who were either psychologically recommended for mission training (N = 46) or failed in basic aptitude (N = 710) or Assessment Center and interview testing (N = 146)...

INTRODUCTION: Flight-induced neck pain is common in high performance jet pilots, with incidents frequently attributed to high Gz flight maneuvers. The additional load of helmet-mounted night vision goggles (NVG) is believed to increase the risk, possibly from neck muscle strain in counteracting muscles. Hence, the aim was to investigate the effect of NVG on neck muscle strain as well as on the activity level distribution through a simulated flight session in air force pilots. METHODS: In this post hoc randomized crossover trial, four senior air force pilots each completed two identical 1...

INTRODUCTION: Although there are numerous studies that demonstrate that color vision deficient (CVD) individuals perform less well than color vision normal (CVN) individuals in tasks that require discrimination or identification of colored stimuli, there remains a need to quantify the relationship between the type and severity of CVD and performance on operationally relevant tasks. METHODS: Participants were classified as CVN (N = 45) or CVD (N = 49) using the Rabin cone contrast test, which is the standard color vision screening test used by the United States Air Force...

INTRODUCTION: Living in an isolated, confined environment (ICE) can induce conflict, stress, and depression. Computer-based behavioral health countermeasures are appealing for training and treatment in ICEs because they provide confidentiality and do not require communication with the outside environment. We evaluated the Virtual Space Station (VSS), a suite of interactive computer-delivered psychological training and treatment programs, at the Hawaii Space Exploration Analog and Simulation (HI-SEAS) III expedition...

PURPOSE: Diffusion-weighted imaging (DWI) and (18) F-fluorodeoxyglucose-positron emission tomography ((18) F-FDG-PET) independently correlate with malignancy in breast cancer, but the relationship between their structural and metabolic metrics is not completely understood. This study spatially correlates diffusion, perfusion, and glucose avidity in breast cancer with simultaneous PET/MR imaging and compares correlations with clinical prognostics. METHODS: In this Health Insurance Portability and Accountability Act-compliant prospective study, with written informed consent and approval of the institutional review board and using simultaneously acquired FDG-PET and DWI, tissue diffusion (Dt ), and perfusion fraction (fp ) from intravoxel incoherent motion (IVIM) analysis were registered to FDG-PET within 14 locally advanced breast cancers...

Arrangements between those who perform work and those who provide jobs come in many different forms. Standard work arrangements now exist alongside several nonstandard arrangements: agency work, contract work, and gig work. While standard work arrangements are still the most prevalent types, the rise of nonstandard work arrangements, especially temporary agency, contract, and "gig" arrangements, and the potential effects of these new arrangements on worker health and safety have captured the attention of government, business, labor, and academia...

PURPOSE: To develop a new method capable of directly measuring specific absorption rate (SAR) deposited in tissue using the thermoacoustic signal induced by short radiofrequency (RF) pulse excitation. THEORY: A detailed model based on the thermoacoustic wave generation and propagation is presented. METHODS: We propose a new concept for direct measurement of SAR, to be used as a safety assessment/monitoring tool for MRI. The concept involves the use of short bursts of RF energy and the measurement of the resulting thermoacoustic excitation pattern by an array of ultrasound transducers, followed by image reconstruction to yield the 3D SAR distribution...
