In this article the authors attempted to analyze the arguments for considering diabetes as a work-related disease. An overview of literature has been done out of articles published in the years 1980-2016, with the use of combination of key words referring to employment, workplace, and diabetes. The PubMed database was the source of data. The authors indicate that the following arguments are in favor of diabetes being recognized as a work-related disease: diabetes is not an occupational disease, it is not directly related to the work environment or the way the work is performed, but there are observed adverse effects of occupational work-related nuisances, such as night shift work, long work hours, job strain or workplace standing time, which influence its development and course...

PURPOSE: Short-echo-time proton MR spectra at 7T feature nine to 10 distinct macromolecule (MM) resonances that overlap with the signals of metabolites. Typically, a metabolite-nulled in vivo MM spectrum is included in the quantification`s prior knowledge to provide unbiased metabolite quantification. However, this MM model may fail if MMs are pathologically altered. In addition, information about the individual MM peaks is lost. In this study, we aimed to create an improved MM model by parameterization of the in vivo MM spectrum into individual components, and to use this new model to quantify free induction decay MR spectroscopic imaging (FID-MRSI) data...

PURPOSE: 1.5T gradient echo-based R2∗ estimates are standard-of-care for assessing liver iron concentration (LIC). Despite growing popularity of 3T, echo time (TE) limitations prevent 3T liver iron quantitation in the upper half of the clinical range (LIC ⪆20 mg/g). In this work, a 3D radial pulse sequence was assessed to double the dynamic range of 3T LIC estimates. THEORY AND METHODS: The minimum TE limits the dynamic range of pulse sequences to estimate R2∗...

INTRODUCTION: Sexual dysfunctions are well-known side effects of selective serotonin reuptake inhibitor (SSRI) use. Altered libido, erectile dysfunction, vaginal dryness, ejaculatory disorders, and orgasmic problems are frequently reported by patients treated with SSRIs. Moreover, these antidepressant-emergent sexual dysfunctions do not always resolve after discontinuation of the medication and can persist indefinitely. These complaints are termed post-SSRI sexual dysfunctions (PSSD)...

INTRODUCTION: Erectile dysfunction (ED) is an important health concern that can significantly affect a man's psychosocial well-being. ED has traditionally been considered a disease of old age; however, contemporary evidence suggests a growing incidence of ED in men younger than 40 years. The process of achieving an erection is multifaceted; there are many potential mechanisms that can be disrupted. It is critical to identify the specific causes of ED before proceeding with potentially costly and invasive therapeutic options...

INTRODUCTION: Transport operators seeking to operate outside prescriptive fatigue management regulations are typically required to present a safety case justifying how they will manage the associated risk. This paper details a method for constructing a successful safety case. METHODS: The method includes four elements: 1) scope (prescriptive rules and operations affected); 2) risk assessment; 3) risk mitigation strategies; and 4) monitoring ongoing risk. A successful safety case illustrates this method...

Torin K Clark, Laurence R Young
BACKGROUND: Increased gravito-inertial acceleration, or hypergravity, such as produced in a centrifuge or in an aircraft coordinated turn, causes humans to systematically overestimate their roll tilt in the dark. This is known as the "G-excess" illusion. We have previously modified a mathematical observer model of dynamic orientation perception to replicate these illusory tilt perceptions. This modified model also made a novel, previously untested, prediction that humans would underestimate acute roll tilt in reduced gravitational environments (hypogravity)...

BACKGROUND: The few prior studies of time perception underwater have reached contradictory conclusions as to how, and if, time perception becomes distorted when submerged. The current paper expands upon this limited data by describing two studies of prospective time production in scuba divers. METHODS: Study 1 (N = 32) compared performance on a 30-s interval time production task in deep water (35 m-42 m/∼115-138 ft) with a shallow water control (3-12 m/∼10-39 ft)...

In the space environment, the traditional radioprotective principles of time, distance, and shielding become difficult to implement. Additionally, the complex radiation environment inherent in space, the chronic exposure timeframe, and the presence of numerous confounding variables complicate the process of creating appropriate risk models for astronaut exposure. Pharmaceutical options hold tremendous promise to attenuate acute and late effects of radiation exposure in the astronaut population. Pharmaceuticals currently approved for other indications may also offer radiation protection, modulation, or mitigation properties along with a well-established safety profile...

General aviation includes all civilian aviation apart from operations involving paid passenger transport. Unfortunately, this category of aviation holds a lackluster safety record, accounting for 94% of civil aviation fatalities. In 2014, of 1143 general aviation accidents, 20% were fatal compared with 0 of 29 airline mishaps in the United States. Herein, research findings over the past 30 yr will be reviewed. Accident risk factors (e.g., adverse weather, geographical region, post-impact fire, gender differences) will be discussed...
