Sustaining work ability amongst female professional workers with long COVID.

Background: Long COVID (LC) compromises work ability (WA). Female worker WA has been more adversely impacted than WA in men. Exploration of lived experiences could elucidate the WA support required.

Induced defenses as a management tool: Shaping individuals to their environment.

Many prey species can adjust morphology to reduce predation risk in response to predator cues. Enhancing prey defenses using predator cues may improve survival of cultivated species and enhance species restoration efforts, but assessment of such benefits at industrially relevant scales is needed. We examined how raising a model foundation species, oysters (Crassostrea virginica), under commercial hatchery conditions with cues from two common predator species can improve survival across a variety of predator regimes and environmental conditions.

What workers can tell us about post-COVID workability.

Background: The apparent functional impact of post-COVID-19 syndrome has workability implications for large segments of the working-age population.

Aims: To understand obstacles and enablers around self-reported workability of workers following COVID-19, to better guide sustainable workplace accommodations.

Methods: An exploratory online survey comprising quantitative and qualitative questions was disseminated via social media and industry networks between December 2020 and February 2021, yielding usable responses from 145 workers.

HIV-Associated Vacuolar Myelopathy and HIV-Associated Dementia as the Initial Manifestation of HIV/AIDS.

HIV-associated vacuolar myelopathy (HIV-VM) is the most common cause of spinal disease in HIV/AIDS. HIV-VM causes progressive spastic paraparesis, sensory ataxia, and autonomic dysfunction. It is a progressive myelopathy that shares features with subacute combined degeneration seen in vitamin B12 deficiency as well as other neurological diseases and can occur synchronously with HIV-associated dementia (HAD).

Turbidity interferes with foraging success of visual but not chemosensory predators.

Predation can significantly affect prey populations and communities, but predator effects can be attenuated when abiotic conditions interfere with foraging activities. In estuarine communities, turbidity can affect species richness and abundance and is changing in many areas because of coastal development. Many fish species are less efficient foragers in turbid waters, and previous research revealed that in elevated turbidity, fish are less abundant whereas crabs and shrimp are more abundant.

The value of involvement from the perspective of service users and carers engaged in practitioner education: not just a cash nexus.

This paper presents qualitative findings emergent from a participatory action research (PAR) study focused on developing service user and carer involvement in a university setting. The involvement of these experts by experience in practitioner education for health and social care, and nursing in particular, is now an international phenomenon. Adhering to the philosophy and practices of PAR, the project and the writing of this paper have been collectively produced.

Review of preventative behavioural interventions for dermal and respiratory hazards.

Background: No previous systematic review of the evidence base has been undertaken to help occupational health professionals understand how to reliably lower the instance of occupational ill-health through reducing risk-taking behaviour.

Aims: To evaluate the effectiveness and processes of occupational-based behavioural interventions for workers exposed to dermal and respiratory hazards.

Methods: A systematic review was conducted.

Evidence, theory and context: using intervention mapping to develop a worksite physical activity intervention.

Background: The workplace is an ideal setting for health promotion. Helping employees to be more physically active can not only improve their physical and mental health, but can also have economic benefits such as reduced sickness absence. The current paper describes the development of a three month theory-based intervention that aims to increase levels of moderate intensity physical activity amongst employees in sedentary occupations.

Clinical database development: characterization of EEG phenotypes.

We propose development of evidence-based methods to guide clinical intervention in neurobehavioral syndromes based on categorization of individuals using both behavioral measures and quantification of the EEG (qEEG). Review of a large number of clinical EEG and qEEG studies suggests that it is plausible to identify a limited set of individual profiles that characterize the majority of the population. Statistical analysis has already been used to document "clusters" of qEEG features seen in populations of psychiatric patients.

Metacarpal shaft fractures: the effect of shortening on the extensor tendon mechanism.

Spiral and oblique metacarpal shaft fractures frequently develop shortening through the fracture site. The acceptable amount of fracture shortening has not been well established. The goal of this study was to elucidate the acceptable limits of metacarpal shaft fracture shortening in a cadaver model by assessing the magnitude of the metacarpophalangeal (MCP) joint extensor lag produced.

Information in magnetic resonance images: evaluation of signal, noise and contrast.

The assessment of diagnostic image quality for MRI is considered. The assessment of three key image quality determinants is addressed: signal, noise and contrast. There is a distinction between random noise evaluation, for the calculation of the SNR, and structured noise evaluation for the assessment of image artefacts.

The modification of the RF field distribution of surface coils by weakly conducting saline samples.

The modification of the RF field distribution of a surface coil, which is brought about by both loading and skin effect conditions arising from the proximity of weakly conducting saline samples, is demonstrated. A procedure for the calibration of the depth of the spectral acquisition region in depth-pulse localized in vivo spectroscopy is shown to be acceptable.

An evaluation of the effect of fasting on the exercise-induced changes in pH and Pi/PCr from skeletal muscle.

The changes in the response of skeletal muscle to maximal dynamic exercise were investigated in going from a fasted state to a refed state by means of 31P NMR spectroscopy. It was found that in the fasted state, exercise-induced changes in Pi/PCr and in pH were both inhibited, in comparison with those in the refed state.

A proton NMR relaxation evaluation of a model of brain oedema fluid.

Using CSF/protein solutions as models of vasogenic extracellular fluid, the concentration dependences of longitudinal and transverse proton relaxation rates have been measured at 37 degrees C and 100 MHz for the serum proteins, albumin, IgG, a 2.8:1 mixture of albumin and IgG and human serum itself. These measurements have been used to determine the sensitivity of proton relaxation rates to the amount and the type of the protein in oedema fluid, and to establish the significance of both of these factors in relation to a separation of vasogenic from cytotoxic oedema.

Covalent binding of a fluorinated 2-nitroimidazole to EMT-6 tumors in Balb/C mice: detection by F-19 nuclear magnetic resonance at 2.35 T.

A hexafluorinated 2-nitroimidazole (CCI-103F) has been synthesized and its properties as a hypoxic cell binder investigated. The drug has a plasma half-life of 90 min in Balb/C mice and a tumor-to-plasma ratio of 0.8.

The influence of oxygenation on the 19F spin-lattice relaxation rates of fluosol-DA.

The spin-lattice relaxation rates (1/T1) were measured at 94.1 MHz for six peaks in the 19F NMR spectrum of the perfluorochemical blood substitute fluosol-DA, which contains a mixed emulsion of perfluorodecalin and perfluorotripropylamine. Each of these rates increased linearly with the percentage of oxygen dissolved in the emulsion.
